Congenitally Blind

The present study examined specific defense mechanisms involved in perceptions of congenitally blind and sighted respondents. The Defense Mechanism Inventory was given 30 blind and 30 sighted subjects, randomly selected. One-way analyses of variance on specific defenses indicated nonsignificant differences between the groups who tended to show comparable patterns of ego defenses. Findings suggest any discrepancies in perception between such groups are not likely based on differences in the use of various defense mechanisms as measured by the Defense Mechanism Inventory.

This paper describes the use of the Defense Mechanism Test as an aid in helping to assess senior executives in four areas: for selection, development, career strategy, and crisis intervention. The origins of this test, developed to measure the defense mechanisms used to protect the individual from stress, are described. The paper shows how it was used to predict the capacity of trainee fighter pilots to withstand stress and its later application to other stressful occupations. Finally, some ideal types of the test are shown followed by four real test profiles, two of them with their associated histories.

Self Image

In The Sense of an Ending, Julian Barnes portrays the mysterious workings of the human mind as it distorts facts towards the end of a self-image that one can live with. The protagonist in the novel deploys certain psychological defense mechanisms in order to protect himself from feelings of anxiety, only to experience even more profound anxiety due to his excessive use of them. The significance of the present paper lies in its novel view of the book. So far, the critique on the novel has mainly been focused on the workings of time on memory; however, the present paper investigates how psychological defense mechanisms blur the protagonist’s perception of reality and distort his memories. This paper also attempts to attract scholarly interest in the study of psychological defense mechanisms in the study of The Sense of an Ending which has so far been to the best of our knowledge overlooked

Excessive Nutrients

In pancreaticβcells, mitochondrial metabolism translates glucose sensing into signals regulating insulin secretion. Chronic exposure ofβcells to excessive nutrients, namely, glucolipotoxicity, impairsβ-cell function. This is associated with elevated ROS production from overstimulated mitochondria. Mitochondria are not only the major source of cellular ROS, they are also the primary target of ROS attacks. The mitochondrial uncoupling protein UCP2, even though its uncoupling properties are debated, has been associated with protective functions against ROS toxicity. Hormesis, an adaptive response to cellular stresses, might contribute to the protection againstβ-cell death, possibly limiting the development of type 2 diabetes. Mitochondrial hormesis, or mitohormesis, is a defense mechanism observed in ROS-induced stress-responses by mitochondria. Inβcells, mitochondrial damages induced by sublethal exogenous H2O2can induce secondary repair and defense mechanisms. In this context, UCP2 is a marker of mitohormesis, being upregulated following stress conditions. When overexpressed in nonstressed naïve cells, UCP2 confers resistance to oxidative stress. Whether treatment with mitohormetic inducers is sufficient to restore or ameliorate secretory function ofβcells remains to be determined.

A story becomes interesting because of the existence of the characters’ conflicts. This research objectives were to investigate the conflicts and defense mechanisms in Audrey Turner, the main character of Finding Audrey novel written by Sophie Kinsella. This research was conducted in qualitative method by using narrative research design. The collected data were identified, categorized, and analyzed based on literature and psychology perspectives of Islam’s (2016) theory and defense mechanisms by Cramer (2006). The findings show that person vs him/herself as the internal conflict is found 52 times (67.5%). The first external conflict found is person vs person which appears 23 times (29.9%) It is followed by person vs society and person vs nature conflicts, each of which appears once only (1.3%). Three kinds of defense mechanisms are found as well. The denial defense mechanisms are found 72 times (54.1%) whereas projection and identification are each found as many as 48 times (36.1%) and 13 times (9.8%). It means that  Audrey, as the main character, mostly faces conflicts against her own self and feels of fears affected from her anxiety disorder and people around her. To deal with her conflicts, Audrey mostly uses denial as a defense mechanism to protect herself.

And Behavior

The purpose of psychological protection is to maintain the integrity of the "self-concept" of the individual by protecting his consciousness from negative traumatic experiences, fear of failure, anxiety or uncertainty in their actions. The authors who studied this phenomenon in sports note that the psychological protection of the athlete - is a system of mechanisms and methods of mental self-regulation of consciousness and behavior of the individual in extreme mental conditions. Psychological defense mechanisms are manifested in students as a regulatory system that is activated in a situation of internal or external conflict. Based on it, students often show such a defense mechanism as substitution, regression, and compensation. Considering the manifestation of protective mechanisms in boys and girls, we obtained the following indicators: reactive formations (73% in girls and 51% in boys) and projection (73% in girls and 54% in boys) (p <0.05); in boys prevails: suppression (65% in boys and 45% in girls) and intellectualization (69% in boys and 56.1% in girls) (p <0.05). We found differences in the choice of the dominant mechanism of psychological protection by swimming students. The leading mechanism in the studied contingent is substitution, and the least preferred is suppression. The study identified the manifestation of the main mechanisms of psychological protection in students who swim and analyzed certain types of protection with a description of the specific features of the system of protective mechanisms and the level of their impact depending on gender differences.

Defensive Activity

Flavoring compounds of plants play a significant role in plant defense mechanism. Compound responsible for strong sour tamarind flavor has been isolated and identified from Methanol fraction of tamarind leaves (TrMF). Chromatographic and spectral analyses of TrMF revealed the compound to be methyl 2,3,4- trihydroxyhexanoate. This compound showed a strong antioxidant activity as well as strong antimicrobial activity. It showed significant antioxidant activity with Ic50 value of 2.5μg/ml whereas tert-butyl-1-hydroxytoluene and ascorbic acid revealed 26.0μg/ml and 5.0μg/ml, respectively. It also revealed strong inhibitory activity against Aspergellosis disease-causing fungi namely; Aspergillus fumigatus, Aspergillus tamarii and Aspergillus niger at all concentrations. Streptococcus aureus and Escherichia coli were much more sensitive to methyl-trihydroxy-hexanoate at all concentrations than Pseudomonas aeruginosa. This pure compound exhibited concentration dependent inhibitory and stimulatory activity on rice seeds germination and seedling growth. It showed strong inhibitory activity up to 62.5ppm concentration and below this concentration the effect was stimulatory. Methyl- trihydroxyhexanoate exhibited wide range of defensive activity against microbes and crop seeds and also possesses potent antioxidative activity. Thus play an important role in plant defense mechanism and can be utilized as a valuable source of bio-herbicides and pesticides.

Defense mechanisms are mental operations that function outside of awareness. In this sense, they operate in the unconscious mind. Such mechanisms were first identified by Sigmund Freud in connection with psychopathology but later were understood to be part of normal everyday functioning. Defenses serve the purpose of protecting the individual from excessive anxiety and loss of self-esteem. Defense mechanisms have been found to change with age, based on the complexity of the mental operations involved. Once a child understands how a defense mechanism functions, the mechanism tends to be used less frequently and a cognitively more complex mechanism is adopted.

Population Performance

ABSTRACT Organisms are prone to different stressors and have evolved various defense mechanisms. One such defense mechanism is priming, where a mild preceding stress prepares the organism toward an improved stress response. This improved response can strongly vary, and primed organisms have been found to respond with one of three response strategies: a shorter delay to stress, a faster buildup of their response or a more intense response. However, a universal comparative assessment, which response is superior under a given environmental setting, is missing. We investigate the benefits of the three improved responses for microorganisms with an ordinary differential equation model, simulating the impact of an external stress on a microbial population that is either naïve or primed. We systematically assess the resulting population performance for different costs associated with priming and stress conditions. Our results show that independent of stress type and priming costs, the stronger primed response is most beneficial for longer stress phases, while the faster and earlier responses increase population performance and survival probability under short stresses. Competition increases priming benefits and promotes the early stress response. This dependence on the ecological context highlights the importance of including primed response strategies into microbial stress ecology.
