A Preliminary Study of Negative Self-Beliefs in Anorexia Nervosa: A Detailed Exploration of Their Content, Origins and Functional Links to “Not Eating Enough” and Other Characteristic Behaviors

Objective: The study explored the semantic content and origins of negative self-beliefs, and their functional links to “not eating enough” and other behaviors, in participants with anorexia nervosa (AN). Method: Fifteen women meeting DSM-IV criteria for AN were compared with 17 dieting and 18 non-dieting women matched on age and number of years of education. The main outcome measure was a semi-structured interview. Results: Six themes were identified in the beliefs of participants with AN. These were, in order of decreasing frequency, powerlessness (present in all but three AN participants), failure, defectiveness, unattractiveness, worthlessness and emptiness. Importantly, powerlessness and failure beliefs were consistently present independent of Beck Depression Inventory-II scores. The negative early life experiences associated with these beliefs had high distress and responsibility ratings. Participants with AN reported that they employed specific behaviors, particularly ‘not eating enough,’ and ‘placating others,’ to try to reduce the cognitive and emotional impact of their negative self-beliefs. Discussion: The findings are discussed in relation to the role of powerlessness and the function of “not eating enough” in cognitive theory and therapy for AN.

Caring for the Involuntarily Hospitalized Adolescent: The Issue of Power in the Nurse-Patient Relationship

TOPIC: The power relations between involuntarily hospitalized adolescents and their caregivers from the viewpoint of theory development in nursing and the concept of medicalization. PURPOSE: To contribute to the development of nursing theories that can guide nursing care of involuntarily hospitalized adolescents by examining the power relations between the adolescents and their caregivers. SOURCES: Published literature in medical sociology, and nursing and psychiatric ethics. Nursing and psychiatric literature, in which Michel Foucault's theories are used to explicate the disciplinary power of psychiatry. CONCLUSIONS: To empower involuntarily hospitalized adolescents nurses must both recognize the inevitable power imbalance and seek guidance from the egalitarian ideals of nursing. Nurses can draw from postmodern thinkers who dismiss the idea that one theory can explain human relationships.     

A reaction route graph analysis of the electrochemical hydrogen oxidation and evolution reactions

The reaction route (RR) graph approach recently developed by us for complex, non-linear kinetic mechanisms is applied to the hydrogen oxidation and evolution reactions. A corresponding RR graph is constructed and translated into an equivalent electrical circuit network by associating each elementary step with a characteristic resistance for the steady-state case and considering the overall reaction as a power source. It is further shown that the steady-state kinetics of the reaction can be investigated employing the conventional methods of the electrical network theory. Using a set of rate constants for the hydrogen evolution reaction (her) in alkaline solutions from the literature, the dominant RRs are identified and simplified mechanisms and kinetics derived.

对《诸病源候论》毒邪症状界定的分析

《诸病源侯论》论毒邪篇幅之多,明目之清,发前人所未发,打破传统束缚,注重临床实际。如其提出毒邪判断要以阴阳为纲;毒邪向内为病重,向外为病轻;赤白为轻,青紫黑为重;过肘膝为重,以及伤肠胃心肝脾肾均有不同的症状特征,提示了六淫从化于毒,毒邪与六淫有不同表现等问题,值得一读。
