Existential psychotherapy

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Existential_therapy

Existential psychotherapy is a form of psychotherapy based on the model of human nature and experience developed by the existential tradition of European philosophy. It focuses on concepts that are universally applicable to human existence including death, freedom, responsibility, and the meaning of life. Instead of regarding human experiences such as anxiety, alienation and depression as implying the presence of mental illness, existential psychotherapy sees these experiences as natural stages in a normal process of human development and maturation. In facilitating this process of development and maturation existential psychotherapy involves a philosophical exploration of an individual's experiences while stressing the individual's freedom and responsibility to facilitate a higher degree of meaning and well-being in his or her life.

Background

The philosophers who are especially pertinent to the development of existential psychotherapy are those whose works were directly aimed at making sense of human existence. For example, the fields of phenomenology and existential philosophy are especially and directly responsible for the generation of existential therapy.

The starting point of existential philosophy (see Warnock 1970; Macquarrie 1972; Mace 1999; van Deurzen and Kenward 2005) can be traced back to the nineteenth century and the works of Søren Kierkegaard and Friedrich Nietzsche. Their works conflicted with the predominant ideologies of their time and committed to the exploration of reality as it can be experienced in a passionate and personal manner.

Søren Kierkegaard (1813–1855)

Soren Kierkegaard (1813–1855) protested vehemently against popular misunderstanding and abuse of Christian dogma and the so-called 'objectivity' of science (Kierkegaard, 1841, 1844). He thought that both were ways of avoiding the anxiety inherent in human existence. He had great contempt for the way life was lived by those around him and believed truth could only be discovered subjectively by the individual in action. He felt people lacked the courage to take a leap of faith and live with passion and commitment from the inward depth of existence. This involved a constant struggle between the finite and infinite aspects of our nature as part of the difficult task of creating a self and finding meaning. As Kierkegaard lived by his word, he was lonely and much ridiculed during his lifetime.

Friedrich Nietzsche (1844–1900)

Friedrich Nietzsche (1844–1900) took this philosophy of life a step further. His starting point was the notion that God is dead, that is, the idea of God was outmoded and limiting (Nietzsche, 1861, 1874, 1886). Furthermore, the Enlightenment—with the newfound faith in reason and rationality—had killed or replaced God with a new Truth that was perhaps more pernicious than the one it replaced. Science and rationality were the new "God," but instead took the form of a deity that was colder and less comforting than before. Nietzsche exerted a significant impact upon the development of psychology in general, but he specifically influenced an approach which emphasized an understanding of life from a personal perspective. In exploring the various needs of the individual about the ontological conditions of being, Nietzsche asserted that all things are in a state of "ontological privation," in which they long to become more than they are. This state of deprivation has major implications for the physiological and psychological needs of the individual.

Edmund Husserl (1859–1938)

While Kierkegaard and Nietzsche drew attention to the human issues that needed to be addressed, Edmund Husserl's phenomenology (Husserl, 1960, 1962; Moran, 2000) provided the method to address them rigorously. He contended that natural sciences assume the separateness of subject and object and that this kind of dualism can only lead to error. He proposed a whole new mode of investigation and understanding of the world and our experience of it. He said that prejudice has to be put aside or 'bracketed,' for us to meet the world afresh and discover what is absolutely fundamental, and only directly available to us through intuition. If people want to grasp the essence of things, instead of explaining and analyzing them, they have to learn to describe and understand them.

Max Scheler (1874-1928)

Max Scheler (1874-1928) developed philosophical anthropology from a material ethic of values ("Materielle Wertethik") that opposed Immanuel Kant's ethics of duty ("Pflichtethik"). He described a hierarchical system of values that further developed phenomenological philosophy. Scheler described the human psyche as being composed of four layers analogous to the layers of organic nature. However, in his description, the human psyche is opposed by the principle of the human spirit. Scheler's philosophy forms the basis of Viktor Frankl's logotherapy and existential analysis.

Martin Heidegger (1889–1976)

Martin Heidegger (1889–1976) applied the phenomenological method to understanding the meaning of being (Heidegger, 1962, 1968). He argued that poetry and deep philosophical thinking could bring greater insight into what it means to be in the world than what can be achieved through scientific knowledge. He explored human beings in the world in a manner that revolutionized classical ideas about the self and psychology. He recognized the importance of time, space, death, and human relatedness. He also favored hermeneutics, an old philosophical method of investigation, which is the art of interpretation.

Unlike interpretation as practiced in psychoanalysis (which consists of referring a person's experience to a pre-established theoretical framework), this kind of interpretation seeks to understand how the person himself/herself subjectively experiences something.

Jean-Paul Sartre (1905–1980)

Jean-Paul Sartre (1905–1980) contributed many other strands of existential exploration, particularly regarding emotions, imagination, and the person's insertion into a social and political world.

The philosophy of existence, on the contrary, is carried by a wide-ranging literature, which includes many authors, such as Karl Jaspers (1951, 1963), Paul Tillich, Martin Buber, and Hans-Georg Gadamer within the Germanic tradition and Albert Camus, Gabriel Marcel, Paul Ricoeur, Maurice Merleau-Ponty, Simone de Beauvoir and Emmanuel Lévinas within the French tradition (see for instance Spiegelberg, 1972, Kearney, 1986 or van Deurzen-Smith, 1997).

Others

From the start of the 20th century, some psychotherapists were, however, inspired by phenomenology and its possibilities for working with people.

  • Otto Rank (1884–1939), an Austrian psychoanalyst who broke with Freud in the mid-1920s, was the first existential therapist.
  • Ludwig Binswanger, in Switzerland, also attempted to bring existential insights to his work with patients, in the Kreuzlingen sanatorium where he was a psychiatrist.
    • Much of his work was translated into English during the 1940s and 1950s and, together with the immigration to the USA of Paul Tillich (1886–1965) (Tillich, 1952) and others, this had a considerable effect on the popularization of existential ideas as a basis for therapy (Valle and King, 1978; Cooper, 2003).
  • Rollo May (1909–1994) played an important role in this, and his writing (1969, 1983; May et al., 1958) kept the existential influence alive in America, leading eventually to a specific formulation of therapy (Bugental, 1981; May and Yalom, 1985; Yalom, 1980).
  • Viktor Frankl (1905–1997) was possibly the individual most responsible for spreading existential psychology throughout the world. He was invited by over 200 universities worldwide and accomplished over 80 journeys to North America alone, first invited by Gordon Allport at Harvard University.
  • In Europe, after Otto Rank, existential ideas were combined with some psychoanalytic principles and a method of existential analysis was developed by Medard Boss (1903–1990) (1957a, 1957b, 1979) in close co-operation with Heidegger.
  • In France, the ideas of Sartre (1956, 1962) and Merleau-Ponty (1962) and of some practitioners (Minkowski, 1970) were important and influential, but no specific therapeutic method was developed from them.

Development

Development in Europe

The European School of existential analysis is dominated by two forms of therapy: Logotherapy, and Daseinsanalysis. Logotherapy was developed by psychiatrist Viktor E. Frankl. Frankl was heavily influenced by existential philosophy, as well as his own experience in the Nazi concentration camps of World War II. The three main components to Logotherapy are Freedom of Will, which is the ability to change one's life to the degree that such change is possible, Will to Meaning, which places meaning at the center of well-being, and Meaning in Life, which asserts the objectivity of meaning. The primary techniques of Logotherapy involve helping the clients to identify and remove any barriers to the pursuit of meaning in their own lives, to determine what is personally meaningful, and to then help patients effectively pursue related goals.

Daseinsanalysis is a psychotherapeutic system developed upon the ideas of Martin Heidegger, as well as the psychoanalytic theories of Sigmund Freud, that seeks to help the individual find autonomy and meaning in their "being in the world" (a rough translation of "Dasein").

Development in Britain

Britain became a fertile ground for further development of the existential approach when R. D. Laing and David Cooper, often associated with the anti-psychiatry movement, took Sartre's existential ideas as the basis for their work (Laing, 1960, 1961; Cooper, 1967; Laing and Cooper, 1964). Without developing a concrete method of therapy, they critically reconsidered the notion of mental illness and its treatment. In the late 1960s, they established an experimental therapeutic community at Kingsley Hall in the East End of London, where people could come to live through their 'madness' without the usual medical treatment. They also founded the Philadelphia Association, an organization providing an alternative living, therapy, and therapeutic training from this perspective. The Philadelphia Association is still in existence today and is now committed to the exploration of the works of philosophers such as Ludwig Wittgenstein, Jacques Derrida, Levinas, and Michel Foucault as well as the work of the French psychoanalyst Jacques Lacan. It also runs some small therapeutic households along these lines. The Arbours Association is another group that grew out of the Kingsley Hall experiment. Founded by Joseph Berke and Schatzman in the 1970s, it now runs a training program in psychotherapy, a crisis center, and several therapeutic communities. The existential input in the Arbours has gradually been replaced with a more neo-Kleinian emphasis.

The impetus for further development of the existential approach in Britain has primarily come from the development of some existentially based courses in academic institutions. This started with the programs created by Emmy van Deurzen, initially at Antioch University in London and subsequently at Regent's College, London and since then at the New School of Psychotherapy and Counseling, also located in London. The latter is a purely existentially based training institute, which offers postgraduate degrees validated by the University of Sheffield and Middlesex University. In the past few decades, the existential approach has spread rapidly and has become a welcome alternative to established methods. There are now many other, mostly academic, centers in Britain that provide training in existential counseling and psychotherapy and a rapidly growing interest in the approach in the voluntary sector and the National Health Service.

British publications dealing with existential therapy include contributions by these authors: Jenner (de Koning and Jenner, 1982), Heaton (1988, 1994), Cohn (1994, 1997), Spinelli (1997), Cooper (1989, 2002), Eleftheriadou (1994), Lemma-Wright (1994), Du Plock (1997), Strasser and Strasser (1997), van Deurzen (1997, 1998, 2002), van Deurzen and Arnold-Baker (2005), and van Deurzen and Kenward (2005). Other writers such as Lomas (1981) and Smail (1978, 1987, 1993) have published work relevant to the approach, although not explicitly 'existential' in orientation. The journal of the British Society for Phenomenology regularly publishes work on existential and phenomenological psychotherapy. The Society for Existential Analysis was founded in 1988, initiated by van Deurzen. This society brings together psychotherapists, psychologists, psychiatrists, counselors, and philosophers working from an existential perspective. It offers regular fora for discussion and debate as well as significant annual conferences. It publishes the Journal of the Society for Existential Analysis twice a year. It is also a member of the International Federation of Daseinsanalysis, which stimulates international exchange between representatives of the approach from around the world. An International Society for Existential Therapists also exists. It was founded in 2006 by Emmy van Deurzen and Digby Tantam and is called the International Community of Existential Counsellors and Therapists (ICECAP).

Development in Canada

New developments in existential therapy in the last 20 years include existential positive psychology and meaning therapy. Different from the traditional approach to existential therapy, these new developments incorporate research findings from contemporary positive psychology.

Existential positive psychology can reframe the traditional issues of existential concerns into positive psychology questions that can be subjected to empirical research. It also focuses on personal growth and transformation as much as on existential anxiety. Later, existential positive psychology was incorporated into the second wave of positive psychology.

Meaning therapy (MT) is an extension of Frankl's logotherapy and America's humanistic-existential tradition; it is also pluralistic because it incorporates elements of cognitive-behavioral therapy, narrative therapy, and positive psychotherapy, with meaning as its central organizing construct. MT not only appeals to people's natural desires for happiness and significance but also makes skillful use of their innate capacity for meaning-seeking and meaning-making. MT strikes a balance between a person-centered approach and a psycho-educational approach. At the outset of therapy, clients are informed of the use of meaning-centered interventions appropriate for their predicaments because of the empirical evidence for the vital role of meaning in healing and thriving. MT is a comprehensive and pluralistic way to address all aspects of clients' existential concerns. Clients can benefit from MT in two ways: (1) a custom-tailored treatment to solve their presenting problems, and (2) a collaborative journey to create a preferred better future.

View of the human mind

Existential therapy (of the American, existential-humanistic tradition) starts with the belief that although humans are essentially alone in the world, they long to be connected to others. People want to have meaning in one another's lives, but ultimately they must come to realize that they cannot depend on others for validation, and with that realization, they finally acknowledge and understand that they are fundamentally alone. The result of this revelation is anxiety in the knowledge that our validation must come from within and not from others.

Existential therapy is based on a theory of mind, and of psychology. In existentialism, personality is based on choosing to be, authentically, the real you, given an understanding based on a philosophical idea of what a person is. Therefore, practical therapeutic applications can be derived given a theory of personality, emotion, and “the good life.”

This leads to practical therapeutic applications like dealing with personal choices in life that lead to personal happiness. Personal happiness based on a concept of yourself as having the freedom of directing your life and making necessary changes (so to speak, a radical freedom). So, a full philosophical understanding of existentialism is basic to methods implemented for emotional and life changes. That is, a background in philosophy is basic to existential therapy.

Philosophical issues of the self, personality, philosophy of mind, meaning of life, personal development are all fundamentally relevant to any practical therapeutic expectations.

Psychological dysfunction

Because there is no single existential view, opinions about psychological dysfunction vary.

For theorists aligned with Yalom, psychological dysfunction results from the individual's refusal or inability to deal with the normal existential anxiety that comes from confronting life's "givens": death, freedom, isolation, and meaninglessness.

For other theorists, there is no such thing as psychological dysfunction or mental illness. Every way of being is merely an expression of how one chooses to live one's life. However, one may feel unable to come to terms with the anxiety of being alone in the world. If so, an existential psychotherapist can assist one in accepting these feelings rather than trying to change them as if there is something wrong. Everyone has the freedom to choose how they are going to exist in life; however, this freedom may go unpracticed. It may appear easier and safer not to make decisions that one will be responsible for. Many people will remain unaware of alternative choices in life for various societal reasons.

The good life

Existentialism suggests that it is possible for individuals to face the anxieties of life head on, embrace the human condition of aloneness and to revel in the freedom to choose and take full responsibility for their choices. They can aim to take control of their lives and steer themselves in any direction they choose. There is no need to halt feelings of meaninglessness but instead to choose and focus on new meanings for the living. By building, loving and creating, life can be lived as one's own adventure. One can accept one's own mortality and overcome the fear of death. Although the French author Albert Camus denied the specific label of existentialist in his novel, L'Etranger, the novel's main character, Meursault, ends the novel by doing just this. He accepts his mortality and rejects the constrictions of society he previously placed on himself, leaving him unencumbered and free to live his life with an unclouded mind. Also, Gerd B. Achenbach has refreshed the Socratic tradition with his own blend of philosophical counseling, as has Michel Weber with his Chromatiques Center in Belgium.

The strictly Sartrean perspective of existential psychotherapy is generally unconcerned with the client's past, but instead, the emphasis is on the choices to be made in the present and future. The counselor and the client may reflect upon how the client has answered life's questions in the past, but attention ultimately shifts to searching for a new and increased awareness in the present and enabling a new freedom and responsibility to act. The patient can then accept that they are not special and that their existence is simply coincidental, or without destiny or fate. By accepting this, they can overcome their anxieties and instead view life as moments in which they are fundamentally free.

Four worlds

Existential thinkers seek to avoid restrictive models that categorize or label people. Instead, they look for the universals that can be observed cross-culturally. There is no existential personality theory which divides humanity into types or reduces people to part components. Instead, there is a description of the different levels of experience and existence with which people are inevitably confronted. The way in which a person is in the world at a particular stage can be charted on this general map of human existence (Binswanger, 1963; Yalom, 1980; van Deurzen, 1984).

In line with the view taken by van Deurzen, one can distinguish four basic dimensions of human existence: the physical, the social, the psychological, and the spiritual.

On each of these dimensions, people encounter the world and shape their attitude out of their particular take on their experience. Their orientation towards the world defines their reality. The four dimensions are interwoven and provide a complex four-dimensional force field for their existence. Individuals are stretched between a positive pole of what they aspire to on each dimension and a negative pole of what they fear. Binswanger proposed the first three of these dimensions from Heidegger's description of Umwelt and Mitwelt and his further notion of Eigenwelt. The fourth dimension was added by van Deurzen from Heidegger's description of a spiritual world (Überwelt) in Heidegger's later work.

Physical dimension

On the physical dimension (Umwelt), individuals relate to their environment and the givens of the natural world around them. This includes their attitude to the body they have, to the concrete surroundings they find themselves in, to the climate and the weather, to objects and material possessions, to the bodies of other people, their own bodily needs, to health and illness and their mortality. The struggle on this dimension is, in general terms, between the search for domination over the elements and natural law (as in technology, or in sports) and the need to accept the limitations of natural boundaries (as in ecology or old age). While people generally aim for security on this dimension (through health and wealth), much of life brings a gradual disillusionment and realization that such security can only be temporary. Recognizing limitations can deliver a significant release of tension.

Social dimension

On the social dimension (Mitwelt), individuals relate to others as they interact with the public world around them. This dimension includes their response to the culture they live in, as well as to the class and race they belong to (and also those they do not belong to). Attitudes here range from love to hate and from cooperation to competition. The dynamic contradictions can be understood concerning acceptance versus rejection or belonging versus isolation. Some people prefer to withdraw from the world of others as much as possible. Others blindly chase public acceptance by going along with the rules and fashions of the moment. Otherwise, they try to rise above these by becoming trendsetters themselves. By acquiring fame or other forms of power, individuals can attain dominance over others temporarily. Sooner or later, however, everyone is confronted with both failure and aloneness.

Psychological dimension

On the psychological dimension (Eigenwelt), individuals relate to themselves and in this way create a personal world. This dimension includes views about their character, their past experience and their future possibilities. Contradictions here are often experienced regarding personal strengths and weaknesses. People search for a sense of identity, a feeling of being substantial and having a self.

But inevitably many events will confront them with evidence to the contrary and plunge them into a state of confusion or disintegration. Activity and passivity are an important polarity here. Self-affirmation and resolution go with the former and surrender and yielding with the latter. Facing the final dissolution of self that comes with personal loss and the facing of death might bring anxiety and confusion to many who have not yet given up their sense of self-importance.

Spiritual dimension

On the spiritual dimension (Überwelt) (van Deurzen, 1984), individuals relate to the unknown and thus create a sense of an ideal world, an ideology, and a philosophical outlook. It is there that they find meaning by putting all the pieces of the puzzle together for themselves. For some people, this is done by adhering to a religion or other prescriptive worldview; for others, it is about discovering or attributing meaning in a more secular or personal way. The contradictions that must be faced on this dimension are often related to the tension between purpose and absurdity, hope and despair. People create their values in search of something that matters enough to live or die for, something that may even have ultimate and universal validity. Usually, the aim is the conquest of a soul or something that will substantially surpass mortality (as in having contributed something valuable to humankind). Facing the void and the possibility of nothingness are the indispensable counterparts of this quest for the eternal.

Research support

There has not been a tremendous amount of research on existential therapy. Much of the research focuses on people receiving therapy who also have medical concerns such as cancer. Despite this, some studies have indicated positive efficacy for existential therapies with certain populations. Overall, however, more research is needed before definitive scientific claims can be made.

Genetically modified plant

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Genetically_modified_plant

Genetically modified plants
have been engineered for scientific research, to create new colours in plants, deliver vaccines, and to create enhanced crops. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors. Many plant cells are pluripotent, meaning that a single cell from a mature plant can be harvested and then under the right conditions form a new plant. This ability is most often taken advantage by genetic engineers through selecting cells that can successfully be transformed into an adult plant which can then be grown into multiple new plants containing transgene in every cell through a process known as tissue culture.

Research

Much of the advances in the field genetic engineering has come from experimentation with tobacco. Major advances in tissue culture and plant cellular mechanisms for a wide range of plants has originated from systems developed in tobacco. It was the first plant to be genetically engineered and is considered a model organism for not only genetic engineering, but a range of other fields. As such the transgenic tools and procedures are well established making it one of the easiest plants to transform. Another major model organism relevant to genetic engineering is Arabidopsis thaliana. Its small genome and short life cycle makes it easy to manipulate and it contains many homologs to important crop species. It was the first plant sequenced, has abundant bioinformatic resources and can be transformed by simply dipping a flower in a transformed Agrobacterium solution.

In research, plants are engineered to help discover the functions of certain genes. The simplest way to do this is to remove the gene and see what phenotype develops compared to the wild type form. Any differences are possibly the result of the missing gene. Unlike mutagenisis, genetic engineering allows targeted removal without disrupting other genes in the organism. Some genes are only expressed in certain tissue, so reporter genes, like GUS, can be attached to the gene of interest allowing visualisation of the location. Other ways to test a gene is to alter it slightly and then return it to the plant and see if it still has the same effect on phenotype. Other strategies include attaching the gene to a strong promoter and see what happens when it is over expressed, forcing a gene to be expressed in a different location or at different developmental stages.

Ornamental

Some genetically modified plants are purely ornamental. They are modified for flower color, fragrance, flower shape and plant architecture. The first genetically modified ornamentals commercialised altered colour. Carnations were released in 1997, with the most popular genetically modified organism, a blue rose (actually lavender or mauve) created in 2004. The roses are sold in Japan, the United States, and Canada. Other genetically modified ornamentals include Chrysanthemum and Petunia. As well as increasing aesthetic value there are plans to develop ornamentals that use less water or are resistant to the cold, which would allow them to be grown outside their natural environments.

Conservation

It has been proposed to genetically modify some plant species threatened by extinction to be resistant invasive plants and diseases, such as the emerald ash borer in North American and the fungal disease, Ceratocystis platani, in European plane trees. The papaya ringspot virus (PRSV) devastated papaya trees in Hawaii in the twentieth century until transgenic papaya plants were given pathogen-derived resistance. However, genetic modification for conservation in plants remains mainly speculative. A unique concern is that a transgenic species may no longer bear enough resemblance to the original species to truly claim that the original species is being conserved. Instead, the transgenic species may be genetically different enough to be considered a new species, thus diminishing the conservation worth of genetic modification.

Crops

Genetically modified crops are genetically modified plants that are used in agriculture. The first crops provided are used for animal or human food and provide resistance to certain pests, diseases, environmental conditions, spoilage or chemical treatments (e.g. resistance to a herbicide). The second generation of crops aimed to improve the quality, often by altering the nutrient profile. Third generation genetically modified crops can be used for non-food purposes, including the production of pharmaceutical agents, biofuels, and other industrially useful goods, as well as for bioremediation.

There are three main aims to agricultural advancement; increased production, improved conditions for agricultural workers and sustainability. GM crops contribute by improving harvests through reducing insect pressure, increasing nutrient value and tolerating different abiotic stresses. Despite this potential, as of 2018, the commercialised crops are limited mostly to cash crops like cotton, soybean, maize and canola and the vast majority of the introduced traits provide either herbicide tolerance or insect resistance. Soybeans accounted for half of all genetically modified crops planted in 2014. Adoption by farmers has been rapid, between 1996 and 2013, the total surface area of land cultivated with GM crops increased by a factor of 100, from 17,000 square kilometers (4,200,000 acres) to 1,750,000 km2 (432 million acres). Geographically though the spread has been very uneven, with strong growth in the Americas and parts of Asia and little in Europe and Africa. Its socioeconomic spread has been more even, with approximately 54% of worldwide GM crops grown in developing countries in 2013.

Food

The majority of GM crops have been modified to be resistant to selected herbicides, usually a glyphosate or glufosinate based one. Genetically modified crops engineered to resist herbicides are now more available than conventionally bred resistant varieties; in the USA 93% of soybeans and most of the GM maize grown is glyphosate tolerant. Most currently available genes used to engineer insect resistance come from the Bacillus thuringiensis bacterium. Most are in the form of delta endotoxin genes known as cry proteins, while a few use the genes that encode for vegetative insecticidal proteins. The only gene commercially used to provide insect protection that does not originate from B. thuringiensis is the Cowpea trypsin inhibitor (CpTI). CpTI was first approved for use cotton in 1999 and is currently undergoing trials in rice. Less than one percent of GM crops contained other traits, which include providing virus resistance, delaying senescence, modifying flower colour and altering the plants composition. Golden rice is the most well known GM crop that is aimed at increasing nutrient value. It has been engineered with three genes that biosynthesise beta-carotene, a precursor of vitamin A, in the edible parts of rice. It is intended to produce a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A. a deficiency which each year is estimated to kill 670,000 children under the age of 5 and cause an additional 500,000 cases of irreversible childhood blindness. The original golden rice produced 1.6μg/g of the carotenoids, with further development increasing this 23 times. In 2018 it gained its first approvals for use as food.

Biopharmaceuticals

Plants and plant cells have been genetically engineered for production of biopharmaceuticals in bioreactors, a process known as Pharming. Work has been done with duckweed Lemna minor, the algae Chlamydomonas reinhardtii and the moss Physcomitrella patens. Biopharmaceuticals produced include cytokines, hormones, antibodies, enzymes and vaccines, most of which are accumulated in the plant seeds. Many drugs also contain natural plant ingredients and the pathways that lead to their production have been genetically altered or transferred to other plant species to produce greater volume and better products. Other options for bioreactors are biopolymers and biofuels. Unlike bacteria, plants can modify the proteins post-translationally, allowing them to make more complex molecules. They also pose less risk of being contaminated. Therapeutics have been cultured in transgenic carrot and tobacco cells, including a drug treatment for Gaucher's disease.

Vaccines

Vaccine production and storage has great potential in transgenic plants. Vaccines are expensive to produce, transport and administer, so having a system that could produce them locally would allow greater access to poorer and developing areas. As well as purifying vaccines expressed in plants, it is also possible to produce edible vaccines in plants. Edible vaccines stimulate the immune system when ingested to protect against certain diseases. Being stored in plants reduces the long-term cost as they can be disseminated without the need for cold storage, do not need to be purified, and have long term stability. Also being housed within plant cells provides some protection from the gut acids upon digestion; the cost of developing, regulating and containing transgenic plants is high, leading to most current plant-based vaccine development being applied to veterinary medicine, where the controls are not as strict.

Ethnocentrism

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Ethnocentrism
Polish sociologist Ludwig Gumplowicz is believed to have coined the term "ethnocentrism" in the 19th century, although he may have merely popularized it.

Ethnocentrism in social science and anthropology—as well as in colloquial English discourse—means to apply one's own culture or ethnicity as a frame of reference to judge other cultures, practices, behaviors, beliefs, and people, instead of using the standards of the particular culture involved. Since this judgment is often negative, some people also use the term to refer to the belief that one's culture is superior to, or more correct or normal than, all others—especially regarding the distinctions that define each ethnicity's cultural identity, such as language, behavior, customs, and religion. In common usage, it can also simply mean any culturally biased judgment. For example, ethnocentrism can be seen in the common portrayals of the Global South and the Global North.

Ethnocentrism is sometimes related to racism, stereotyping, discrimination, or xenophobia. However, the term "ethnocentrism" does not necessarily involve a negative view of the others' race or indicate a negative connotation. The opposite of ethnocentrism is cultural relativism, a guiding philosophy stating that the best way to understand a different culture is through their perspective rather than judging them from the subjective viewpoints shaped by one's own cultural standards.

The term "ethnocentrism" was first applied in the social sciences by American sociologist William G. Sumner. In his 1906 book, Folkways, Sumner describes ethnocentrism as "the technical name for the view of things in which one's own group is the center of everything, and all others are scaled and rated with reference to it." He further characterized ethnocentrism as often leading to pride, vanity, the belief in one's own group's superiority, and contempt for outsiders.

Over time, ethnocentrism developed alongside the progression of social understandings by people such as social theorist Theodore W. Adorno. In Adorno's The Authoritarian Personality, he and his colleagues of the Frankfurt School established a broader definition of the term as a result of "in group-out group differentiation", stating that ethnocentrism "combines a positive attitude toward one's own ethnic/cultural group (the in-group) with a negative attitude toward the other ethnic/cultural group (the out-group)." Both of these juxtaposing attitudes are also a result of a process known as social identification and social counter-identification.

Origins and development

The term ethnocentrism derives from two Greek words: "ethnos", meaning nation, and "kentron", meaning center. Scholars believe this term was coined by Polish sociologist Ludwig Gumplowicz in the 19th century, although alternate theories suggest that he only popularized the concept as opposed to inventing it. He saw ethnocentrism as a phenomenon similar to the delusions of geocentrism and anthropocentrism, defining Ethnocentrism as "the reasons by virtue of which each group of people believed it had always occupied the highest point, not only among contemporaneous peoples and nations, but also in relation to all peoples of the historical past."

Subsequently, in the 20th century, American social scientist William G. Sumner proposed two different definitions in his 1906 book Folkways. Sumner stated that "Ethnocentrism is the technical name for this view of things in which one's own group is the center of everything, and all others are scaled and rated with reference to it." In the War and Other Essays (1911), he wrote that "the sentiment of cohesion, internal comradeship, and devotion to the in-group, which carries with it a sense of superiority to any out-group and readiness to defend the interests of the in-group against the out-group, is technically known as ethnocentrism." According to Boris Bizumic, it is a popular misunderstanding that Sumner originated the term ethnocentrism, stating that in actuality, he brought ethnocentrism into the mainstreams of anthropology, social science, and psychology through his English publications.

Several theories have been reinforced through the social and psychological understandings of ethnocentrism including T.W Adorno's Authoritarian Personality Theory (1950), Donald T. Campbell's Realistic Group Conflict Theory (1972), and Henri Tajfel's Social identity theory (1986). These theories have helped to distinguish ethnocentrism as a means to better understand the behaviors caused by in-group and out-group differentiation throughout history and society.

Ethnocentrism in social sciences

William Graham Sumner

In social sciences, ethnocentrism means to judge another culture based on the standard of one's own culture instead of the standard of the other particular culture. When people use their own culture as a parameter to measure other cultures, they often tend to think that their culture is superior and see other cultures as inferior and bizarre. Ethnocentrism can be explained at different levels of analysis. For example, at an intergroup level, this term is seen as a consequence of a conflict between groups; while at the individual level, in-group cohesion and out-group hostility can explain personality traits. Also, ethnocentrism can helps us to explain the construction of identity. Ethnocentrism can explain the basis of one's identity by excluding the outgroup that is the target of ethnocentric sentiments and used as a way of distinguishing oneself from other groups that can be more or less tolerant. This practice in social interactions creates social boundaries, such boundaries define and draw symbolic boundaries of the group that one wants to be associated with or belong to. In this way, ethnocentrism is a term not only limited to anthropology but also can be applied to other fields of social sciences like sociology or psychology. Ethnocentrism may be particularly enhanced in the presence of interethnic competition, hostility and violence. On the other hand, ethnocentrism may negatively influence expatriate worker's performance.

A more recent interpretation of ethnocentrism, which expands upon the work of Claude Lévi-Strauss, highlights its positive dimension. Political sociologist Audrey Alejandro of the London School of Economics argues that, while ethnocentrism does produce social hierarchies, it also produces diversity by maintaining the different dispositions, practices, and knowledge of identity groups. Diversity is both fostered and undermined by ethnocentrism. Ethnocentrism, for Alejandro, is therefore neither something to be suppressed nor celebrated uncritically. Rather, observers can cultivate a 'balanced ethnocentrism', (individual self worth) allowing themselves to be challenged and transformed by difference whilst still protecting difference.

Anthropology

The classifications of ethnocentrism originate from the studies of anthropology. With its omnipresence throughout history, ethnocentrism has always been a factor in how different cultures and groups related to one another. Examples including how historically, foreigners would be characterized as "Barbarians". These trends exist in complex societies, e.g., "the Jews consider themselves to be the 'chosen people', and the Greeks defend all foreigners as 'barbarians'", and how China believed their country to be "the centre of the world". However, the anthropocentric interpretations initially took place most notably in the 19th century when anthropologists began to describe and rank various cultures according to the degree to which they had developed significant milestones, such as monotheistic religions, technological advancements, and other historical progressions.

Most rankings were strongly influenced by colonization and the belief to improve societies they colonized, ranking the cultures based on the progression of their western societies and what they classified as milestones. Comparisons were mostly based on what the colonists believed as superior and what their western societies have accomplished. Victorian era politician and historian Thomas Macaulay once claimed that "one shelf of a Western library" had more knowledge than the centuries of text and literature written by Asian cultures. Ideas developed by Western scientists such as Herbert Spencer, including the concept of the "survival of the fittest", contained ethnocentric ideals; influencing the belief that societies which were 'superior' were most likely to survive and prosper. Edward Said's concept of Orientalism represented how Western reactions to non-Western societies were based on an "unequal power relationship" that the Western world developed due to its history of colonialism and the influence it held over non-Western societies.

The ethnocentric classification of "primitive" were also used by 19th and 20th century anthropologists and represented how unawareness in cultural and religious understanding changed overall reactions to non-Western societies. 19th-century anthropologist Edward Burnett Tylor wrote about "primitive" societies in Primitive Culture (1871), creating a "civilization" scale where it was implied that ethnic cultures preceded civilized societies. The use of "savage" as a classification is modernly known as "tribal" or "pre-literate" where it was usually referred as a derogatory term as the "civilization" scale became more common. Examples that demonstrate a lack of understanding include when European travelers judged different languages based on the fact that they could not understand it and displayed a negative reaction, or the intolerance displayed by Westerners when exposed to unknown religions and symbolisms. Georg Wilhelm Friedrich Hegel, a German philosopher, justified Western imperialism by reasoning that since the non-Western societies were "primitive" and "uncivilized", their culture and history was not worth conserving and thus should welcome Westernization.

Anthropologist Franz Boas saw the flaws in this formulaic approach to ranking and interpreting cultural development and committed himself to overthrowing this inaccurate reasoning due to many factors involving their individual characteristics. With his methodological innovations, Boas sought to show the error of the proposition that race determined cultural capacity. In his 1911 book The Mind of Primitive Man, Boas wrote that:

It is somewhat difficult for us to recognize that the value which we attribute to our own civilization is due to the fact that we participate in this civilization, and that it has been controlling all our actions from the time of our birth; but it is certainly conceivable that there may be other civilizations, based perhaps on different traditions and on a different equilibrium of emotion and reason, which are of no less value than ours, although it may be impossible for us to appreciate their values without having grown up under their influence.

Together, Boas and his colleagues propagated the certainty that there are no inferior races or cultures. This egalitarian approach introduced the concept of cultural relativism to anthropology, a methodological principle for investigating and comparing societies in as unprejudiced a way as possible and without using a developmental scale as anthropologists at the time were implementing. Boas and anthropologist Bronisław Malinowski argued that any human science had to transcend the ethnocentric views that could blind any scientist's ultimate conclusions.

Both had also urged anthropologists to conduct ethnographic fieldwork to overcome their ethnocentrism. To help, Malinowski would develop the theory of functionalism as guides for producing non-ethnocentric studies of different cultures. Classic examples of anti-ethnocentric anthropology include Margaret Mead's Coming of Age in Samoa (1928), which in time has met with severe criticism for its incorrect data and generalisations, Malinowski's The Sexual Life of Savages in North-Western Melanesia (1929), and Ruth Benedict's Patterns of Culture (1934). Mead and Benedict were two of Boas's students.

Scholars generally agree that Boas developed his ideas under the influence of the German philosopher Immanuel Kant. Legend has it that, on a field trip to the Baffin Islands in 1883, Boas would pass the frigid nights reading Kant's Critique of Pure Reason. In that work, Kant argued that human understanding could not be described according to the laws that applied to the operations of nature, and that its operations were therefore free, not determined, and that ideas regulated human action, sometimes independent of material interests. Following Kant, Boas pointed out the starving Eskimos who, because of their religious beliefs, would not hunt seals to feed themselves, thus showing that no pragmatic or material calculus determined their values.

Causes

Ethnocentrism is believed to be a learned behavior embedded into a variety of beliefs and values of an individual or group.

Due to enculturation, individuals in in-groups have a deeper sense of loyalty and are more likely to following the norms and develop relationships with associated members. Within relation to enculturation, ethnocentrism is said to be a transgenerational problem since stereotypes and similar perspectives can be enforced and encouraged as time progresses. Although loyalty can increase better in-grouper approval, limited interactions with other cultures can prevent individuals to have an understanding and appreciation towards cultural differences resulting in greater ethnocentrism.

The social identity approach suggests that ethnocentric beliefs are caused by a strong identification with one's own culture that directly creates a positive view of that culture. It is theorized by Henri Tajfel and John C. Turner that to maintain that positive view, people make social comparisons that cast competing cultural groups in an unfavorable light.

Alternative or opposite perspectives could cause individuals to develop naïve realism and be subject to limitations in understandings. These characteristics can also lead to individuals to become subject to ethnocentrism, when referencing out-groups, and black sheep effect, where personal perspectives contradict those from fellow in-groupers.

Realistic conflict theory assumes that ethnocentrism happens due to "real or perceived conflict" between groups. This also happens when a dominant group may perceive the new members as a threat. Scholars have recently demonstrated that individuals are more likely to develop in-group identification and out-group negatively in response to intergroup competition, conflict, or threat.

Although the causes of ethnocentric beliefs and actions can have varying roots of context and reason, the effects of ethnocentrism has had both negative and positive effects throughout history. The most detrimental effects of ethnocentrism resulting into genocide, apartheid, slavery, and many violent conflicts. Historical examples of these negative effects of ethnocentrism are The Holocaust, the Crusades, the Trail of Tears, and the internment of Japanese Americans. These events were a result of cultural differences reinforced inhumanely by a majority group who thought of themselves as superior. In his 1976 book on evolution, The Selfish Gene, evolutionary biologist Richard Dawkins writes that "blood-feuds and inter-clan warfare are easily interpretative in terms of Hamilton's genetic theory." Simulation-based experiments in evolutionary game theory have attempted to provide an explanation for the selection of ethnocentric-strategy phenotypes.

The positive examples of ethnocentrism throughout history have aimed to prohibit the callousness of ethnocentrism and reverse the perspectives of living in a single culture. These organizations can include the formation of the United Nations; aimed to maintain international relations, and the Olympic Games; a celebration of sports and friendly competition between cultures.

Effects

A study in New Zealand was used to compare how individuals associate with in-groups and out-groupers and has a connotation to discrimination. Strong in-group favoritism benefits the dominant groups and is different from out-group hostility and/or punishment. A suggested solution is to limit the perceived threat from the out-group that also decreases the likeliness for those supporting the in-groups to negatively react.

Ethnocentrism also influences consumer preference over which goods they purchase. A study that used several in-group and out-group orientations have shown a correlation between national identity, consumer cosmopolitanism, consumer ethnocentrism, and the methods consumers choose their products, whether imported or domestic. Consumer Ethnocentrism in which beliefs held by consumers in which they determine which they determine what foreign goods to consume. A study based on the study of consumers was used to determine that Chinese, we skeptical about purchasing product from Japan, due to the deaths created by World War II. Ethnocentrism not only causes effects upon a product

Ethnocentrism and racism

Ethnocentrism is usually associated with racism. However, as mentioned before, ethnocentrism does not necessarily implicate a negative connotation. In European research, the term racism is not linked to ethnocentrism because Europeans avoid applying the concept of race to humans; meanwhile, using this term is not a problem for American researchers. Since ethnocentrism implicated a strong identification with one's in-group, it mostly automatically leads to negative feelings and stereotyping to the members of the outgroup, which can be confused with racism. Finally, scholars agree that avoiding stereotypes is an indispensable prerequisite to overcome ethnocentrism; and mass media play a key role regarding this issue. The differences that each culture possess causes could hinder one another leading to ethnocentrism and racism. A Canadian study established the differences among French Canadian and English Canadian respondents based on products that would be purchased due to ethnocentrism and racism. Due to how diverse the world has become, society has begun to misinterpret the term cultural diversity, by using ethnocentrism to create controversy among all cultures.

Effects of ethnocentrism in the media

Mass media plays an important role in our current society. We are constantly exposed to media content every day. Researchers had found that ethnocentrism is dysfunctional in communication and similar fields because the lack of acceptance of other cultures leads to the creation of barriers for people of different backgrounds to interact with each other. The presence of ethnocentrism in media content creates an issue in the exchange of messages in the communication process. The media industry is dominated by the Global North, so Western ethnocentrism tends to be exposed in the media. This can be seen in the predominance of Western content in TV shows, film, and other forms of mass media. Some shows tend to depict foreign cultures as inferior or strange in contrast to their own culture.

Film

Aladdin from Disney as an example of ethnocentrism

Cinema has been around in our society since the beginning of the 20th century, and it is an important tool made to entertain and/or educate the viewer. Western companies are usually the leaders of the film industry. Thus, it is common to be exposed to content based on Westerners' point of view. Examples of ethnocentrism are constantly seen in films, whether intentionally or unintentionally. An example of this can be seen on the American animated film Aladdin by Disney in 1992; the opening song of the movie is "Arabian Nights", it is mentioned in the lyrics that "it's barbaric, hey, but it's home," which had caused debates among the audience because it could lead to thinking that the Arabic culture is barbaric. Examples like this are numerous, featuring in many Hollywood films. Experts in the field propose that a way of overcoming ethnocentrism is to avoid the use of stereotypes in films. Therefore, the presence of ethnocentrism in cinema leads to stereotypical images of cultures that differ from the creators'. Another film example is a 2018 film named "Crazy Rich Asians", based on the book by Kevin Kwan.

Social media

A considerable number of people are exposed to social media, whose purpose is to encourage interaction among users. Social media has become a reliant source, to be able to interact among others across the world. The most common and popular social media platforms are Facebook, Instagram, Twitter, Snapchat, YouTube, and TikTok. Social media tends to play a positively constructive role within a society in which it educates, guides/entertain the public, and the bring more awareness towards other cultures by illustrating how each one is different from one another. Even though social media can produce positive outcomes within ethnocentrism, there are also negatives in which it allows for other cultures to judge one another and create controversy. Someone who is ethnocentric may hinder the exchange of information by diminishing the interest of interacting with people from other cultures.

Introgression

From Wikipedia, the free encyclopedia
Introgressive phylogenetic clade
A phylogenetic model of introgressive hybridization; the hybrid zone of the two species' lineages is shown in blue, with each horizontal line representing an individual introgressive event.

Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may take many hybrid generations before significant backcrossing occurs. This process is distinct from most forms of gene flow in that it occurs between two populations of different species, rather than two populations of the same species.

Introgression also differs from simple hybridization. Simple hybridization results in a relatively even mixture; gene and allele frequencies in the first generation will be a uniform mix of two parental species, such as that observed in mules. Introgression, on the other hand, results in a complex, highly variable mixture of genes, and may only involve a minimal percentage of the donor genome.

Definition

Introgression or introgressive hybridization is the incorporation (usually via hybridization and backcrossing) of novel genes or alleles from one taxon into the gene pool of a second, distinct taxon. This introgression is considered 'adaptive' if the genetic transfer results in an overall increase in the recipient taxon's fitness.

Ancient introgression events can leave traces of extinct species in present-day genomes, a phenomenon known as ghost introgression.

Source of variation

Introgression is an important source of genetic variation in natural populations and may contribute to adaptation and even adaptive radiation. It can occur across hybrid zones due to chance, selection or hybrid zone movement. There is evidence that introgression is a ubiquitous phenomenon in plants and animals, including humans, in which it may have introduced the microcephalin D allele.

It has been proposed that, historically, introgression with wild animals is a large contributor to the wide range of diversity found in domestic animals, rather than multiple independent domestication events.

Introgressive hybridization has also been shown to be important in the evolution of domesticated crop species, possibly providing genes that help in their expansion into different environments. A genomic study from New York University Abu Dhabi Center for Genomics and Systems Biology showed that domesticated date palm varieties from North Africa show introgressive hybridization of between 5–18% of its genome from the wild Cretan palm Phoenix theophrasti into Middle East date palms P. dactylifera. This process is also similar to the evolution of apples by hybridization of Central Asian apples with the European crabapple. It has also been shown that indica rice arose when Chinese japonica rice arrived in India about ~4,500 years ago and hybridized with an undomesticated proto-indica or wild O. nivara, and transferred key domestication genes from japonica to indica.

Examples

Humans

There is strong evidence for the introgression of Neanderthal genes and Denisovan genes into parts of the modern human gene pool.

Birds

The Mallard duck is possibly the world's most capable bird to hybridise with other duck species, often to the point of the loss of genetic identity of these species. For example, feral mallard populations have significantly reduced wild populations of the Pacific black duck in New Zealand and Australia through cross-breeding.

Butterflies

One important example of introgression has been observed in studies of mimicry in the butterfly genus Heliconius. This genus includes 43 species and many races with different color patterns. Congeners exhibiting overlapping distributions show similar color patterns. The subspecies H. melpomene amaryllis and H. melpomene timareta ssp. nov. overlap in distribution.

Using the ABBA/BABA test, some researchers have observed that there is about 2% to 5% introgression between the pair of subspecies. Importantly, the introgression is not random. The researchers saw significant introgression in chromosomes 15 and 18, where important mimicry loci are found (loci B/D and N/Yb). They compared both subspecies with H. melpomene agalope, which is a subspecies near H. melpomene amaryllis in entire genome trees. The result of the analysis was that there is no relation between those two species and H. melpomene agalope in the loci B/D and N/Yb. Moreover, they performed the same analysis with two other species with overlapping distributions, H. timareta florencia and H. melpomene agalope. They demonstrated introgression between the two taxa, especially in the loci B/D and N/Yb.

Finally, they concluded their experiments with sliding-window phylogenetic analyses, estimating different phylogenetic trees depending on the different regions of the loci. When a locus is important in the color pattern expression, there is a close phylogenetic relationship between the species. When the locus is not important in the color pattern expression, the two species are phylogenetically distant because there is no introgression at such loci.

Domestic species

Introgression can have a significant impact between wild and domestic populations of animals. This includes household pets, as seen in cats or in dogs.

Plants

Introgression has been observed in several plant species. For instance, a species of iris from southern Louisiana has been studied by Arnold and Bennett (1993) regarding the increased fitness of hybrid variants.

Fish

Espinasa et al. found that introgression between a surface-dwelling members of Astroblepus and a troglomorphic species, Astroblepus pholeter, resulted in the development of previously lost traits in offspring, such as distinct eyes and optic nerves.

Introgression line

An introgression line (IL) is a crop species that contains genetic material artificially derived from a wild relative population through repeated backcrossing. An example of a collection of ILs (called an IL-Library) is the use of chromosome segments from Solanum pennellii (a wild species of tomato) that was introgressed into Solanum lycopersicum (the cultivated tomato). The lines of an IL-library usually cover the complete genome of the donor. Introgression lines allow the study of quantitative trait loci, but also the creation of new varieties by introducing exotic traits.

Lineage fusion

Lineage fusion between two species to form a hybrid lineage.
Lineage fusion on a phylogenetic tree; individual introgression events within the hybrid zone (blue) are shown as horizontal lines. Hybrids are produced before the lineages fuse, but rejoin one of the two lineages. Neither species A nor B remains extant in the area of interest.

Lineage fusion is an extreme variant of introgression that results from the merging of two distinct species or populations. This eventually results in a single population that displaces or replaces the parental species in the region. Some lineage fusion occurs soon after two taxa diverge or speciate, especially if there are few reproductive barriers between lineages. It is not strictly necessary for the two lineages to be closely related, but rather have the ability to produce viable offspring.
