Taboo search by successive confinement: surveying a potential energy surface.

A taboo search for minima on a potential energy surface (PES) is performed by means of confinement molecular dynamics: the molecular dynamics trajectory of the system is successively confined to various basins on the PES that have not been sampled yet. The approach is illustrated for a 13-atom Lennard-Jones cluster. It is shown that the taboo search radically accelerates the process of surveying the PES, with the probability of finding a new minimum defined by a propagating Fermi-like distribution.

Underestimation of subfertility among relatives when using a family history: taboo bias.

Family history is widely used in clinical practice and research in order to study genetic aspects of disorders in general, and is recommended as a tool in the assessment of male subfertility. Unfortunately, little is known about the validity of this tool. In this survey, we sent questionnaires to 474 randomly selected men aged 25-40 years in order to collect data on subfertility among them and their relatives. A nonresponder study was also conducted in order to evaluate selection bias. A personal interview was also performed with some respondents in order to gauge how well the data corresponded with questionnaires that were returned. Two hundred forty-three men (51.3%) completed the questionnaire. The responders reported a significantly lower prevalence of subfertility among their relatives than among themselves. Among brothers, the reported prevalence was about 5 times lower (ie, 3.6%) than among responders (15.3%). The nonresponder study and personal interviews showed that these differences were not caused by a selective response to the survey or by the use of a questionnaire instead of a personal interview. We conclude that subfertility among relatives is severely underestimated through the use of family history, probably because of the taboo of discussing subfertility. Knowledge of subfertility may spread selectively within families, causing substantial misclassification. Therefore, researchers and clinicians should be aware that an inquiry of family history is likely to lead to underestimation of subfertility among relatives.

Taboo topics in addiction treatment. An empirical review of clinical folklore.

This article reviews 11 taboo topics, that is, research findings that question traditional assumptions and teachings of addiction treatment. These topics include: (1) the lack of empirical support for the Minnesota Model; (2) questions about the necessity of Alcoholics Anonymous for maintaining abstinence; (3) the existence of spontaneous remission; (4) the detrimental aspects of labeling; (5) the value of addicted individuals' self-reports; (6) the lack of empirical support for the addictive personality concept; (7) cue exposure as an underutilized intervention; (8) the interactional nature of motivation; (9) the value of smoking cessation in early recovery; (10) the overuse of the addiction concept; and (11) the lack of empirical support for the disease concept of codependency. Misconceptions arise due to the lack of communication between disciplines and the experiential bias of current addiction treatment modalities. Emphasis is placed on the importance of empiricism in order to advance the addiction field beyond faith and supposition.

Is male homosexuality still a cultural taboo for kidney donation?

BACKGROUND: Among the so-called social risk behaviors, male homosexuality is probably one of the most interesting and difficult taboos. Because of changing attitudes of the general population toward irregular sexual behaviors, often considered as markers of unhealthy life styles, there is a need to reconsider at least the most important one-homosexuality. METHODS: A semistructured questionnaire included opinions on homosexuality with respect to kidney donation: Would you consider a male homosexual as a kidney donor? If you were on dialysis, would you accept a kidney from a homosexual donor? This instrument was administered to various groups of the general public and caregivers: high school students (Liceo Classico: 59 students, median age 18 years; Istituto Tecnico: n=108, median age 17); first and fourth year of medical school (n=77, age 19; 46, age 22); continuing medical education (n=44, age 32); third year of nursing school (n=31, age 23); "senior citizen university" (n=51, age 63). RESULTS: Male homosexuality was well accepted for kidney donation (71.6% yes, 9.6% no, 18.8% uncertain/blank). However, the opinions were different among the groups with male students of a technical institute showing discrimination against male homosexuals. In the univariate analysis, opinions differed according to age, gender, and belonging to the health care team. In the multivariate analysis, the latter was the strongest predictor (P<.01). The specific threats for the health are not well known, even among the caregiver population. CONCLUSION: It is difficult to define the role of homosexuality among the so-called social risk behaviors. Negative attitudes existed in some subsets of the population.

The psychology of the unthinkable: taboo trade-offs, forbidden base rates, and heretical counterfactuals.

Five studies explored cognitive, affective, and behavioral responses to proscribed forms of social cognition. Experiments 1 and 2 revealed that people responded to taboo trade-offs that monetized sacred values with moral outrage and cleansing. Experiments 3 and 4 revealed that racial egalitarians were least likely to use, and angriest at those who did use, race-tainted base rates and that egalitarians who inadvertently used such base rates tried to reaffirm their fair-mindedness. Experiment 5 revealed that Christian fundamentalists were most likely to reject heretical counterfactuals that applied everyday causal schemata to Biblical narratives and to engage in moral cleansing after merely contemplating such possibilities. Although the results fit the sacred-value-protection model (SVPM) better than rival formulations, the SVPM must draw on cross-cultural taxonomies of relational schemata to specify normative boundaries on thought.

[Sexuality--a taboo topic?].

Looking at the media one might believe there are no sexual taboos. On the contrary: People hardly discuss their own sexual experiences and behaviour. This applies in equal measure to day-to-day clinical and medical practice, although many studies definitely underline that patients do need information and counselling. The present contribution highlights a few fundamental aspects when treading on such delicate ground and provides helpful pointers.

An additional facet of the incest taboo: a protection of the mating-strategy template.

It is suggested that sexual intercourse between adult males and girls tends to distort an inherent mating-strategy template: female choice of mating partner. The distortion seems to have long-range consequences in the form of myriad psychopathologies, which, in turn, reduce the afflicted individuals' chances for normative marriage and parenting profiles. In addition, a similar dynamic would hypothetically result from adult-male to boy incest. It is suggested that to minimize the chances of adult-child sexual intercourse, incest taboos have historically been reinforced and extended to nonparental adults, especially men, beyond the immediate nuclear family.

Four taboos that may limit the success of psychotherapy.

Painful though it may be, it must be accepted as fact that psychotherapy has a lower success rate than it should. Whatever questions we therapists raise about the validity of research in psychotherapy, whatever the problems in defining success, whatever the arguments about therapeutic outcome studies, we are stuck with a great deal of evidence which indicates that between one-third and two-thirds of patients do not benefit from treatment (Bergin, 1971; Eysenck, 1952, 1966; Garfield et al., 1971). In contrast, behavior modifiers and those using physical treatments such as psychosurgery claim rates of improvement and success which sometimes exceed 90 percent (Baily et al., 1973; Hunter-Brown, 1972; Paul, 1965; Rachman, 1971). This paper examines four current practices which may contribute to our failure. These practices are linked to taboos and examined with a view toward understanding both the functions they serve and the limits they impose on therapeutic effectiveness.

Taboos and clinical research in West Africa.

Moral principles or the rules of conduct are based in the society. If the purpose of ethics in research is to take into consideration the needs and the rights of the experimental subject, his social milieu must then largely determine the ethical considerations of a projected study. The inability to comprehend such rights may often be due to ignorance, disease and his societal values. Blood letting, biopsy and post-mortem examinations may so conflict with local beliefs that so called 'consent' to these is much more than a surrender of the rights of the individual. It is difficult to conform with the highest principles of ethics in research in any uniform society. It is more so when the many variables are further complicated by cultural demands and social taboos. The best custodians of ethical standards must relate intimately with the norms of the local population.

Parenting beliefs and practices of opiate-addicted parents: concealment and taboo.

The lifestyle associated with opiate dependence, including drug taking, the buying and selling of drugs, and contact with other drug users, carries potential risks for the safety and well-being of children of drug-using parents. Based on a qualitative interview study conducted with 50 opiate-dependent parents in Dublin, Ireland, the parenting beliefs and practices in relation to children's exposure to drugs and the associated lifestyle are described. Parents saw their lifestyle as potentially risky for their children and their families. The most common strategy adopted by parents was to conceal their drug-related activities and maintain a strict family taboo about these activities. Intervention programmes should be offered to support effective family communication about parental drug dependence.

"Totem and Taboo" in a latency boy.

Against the background of Freud's "Totem and Taboo" the case of a seven-year-old boy is discusses, focusing on his identification with a cat. Guided by Freud's dialectic thinking and his discussion of the phenomena of patriarchy and matriarchy, one is led to contemplate the totemism of a matriarchally oriented boy. The attempt to understand this child's pathology is based upon the concept of the specificity of a developmental phase. In the light of anthropological data, clinical phenomena are evaluated ontogenetically, in analogy with the recapitulation hypothesis.

[Care during postpartum "confinement." Beliefs and taboos in a group of puerperal women].

In our milieu, postpartum confinement is surrounded by cultural manifestations and taboos which are based on natural, supernatural, and social interpretations. This work has identified the meanings attributed to self-care by puerperae under the theoretical framework of culture. The subjects were women soon after childbirth who attended health units with their children for routine procedures. The results showed that the beliefs revealed a symbolic power in the infrastructure of conducts and behaviors of these women in relation to manifestations and care during the postpartum stage. It is important that health professionals incorporate the values and beliefs of women soon after childbirth into their practice, thus sharing the knowledge involving puerperium and favoring the critical understanding of reality and the promotion of health for mothers and their children.

Taboo and Malay tradition.

According to Malinowski there are no peoples, however primitive, without religion and magic; nor are there any societies lacking either in the scientific attitude or in science (Blumberg 1963). Magic and taboo are resorted to when through the normal use of science, or rational techniques, man is unable to control unpredictable events important to him. Where there is difficulty in predicting the outcome of behaviour, where the results of action are not consonant with effort, where there are great limitions on man's knowledge of vital issues, magical techniques are employed--in short, where circumstances of life are uncertain, uncontrolled and unknown. Magic and animism are systems of thought which give not only the explanation of a single phenomenon, but make it possible to comprehend the totality of the world from one point, as a continuity. Of the three systems of thought--animistic, religious and scientific--animism is perhaps the most consistent and the most exhaustive, the one which explains the world in its entirety.

[Urinary incontinence--taboo during postmenopause].

Urinary incontinence affects 30-60% of all women in the postmenopause. More and more women want to remove the taboo attached to incontinence, because they do not accept the reduction in quality of life, social and domestic activities. Detrusor instability (urge incontinence) and/or urethral sphincter incompetence (genuine stress incontinence) are the principal mechanisms, which lead to involuntary urine loss in older women. It is quite evident that additional factors as hypoestrogenism and urogenital atrophy influence urinary incontinence. Since in the postmenopause urge incontinence combined with urogenital atrophy its found predominantly, pharmacologic therapy with anticholinergic drugs and estrogen replacement are generally effective. Surgical therapy should be restricted to older women with genital prolapse and/or stress incontinence. In genuine stress incontinence, estrogen replacement therapy can lead to subjective improvement, but urodynamic parameters do not change objectively.

[Violence, desire and death. Reflections on 3 taboos in psychiatry].

UNLABELLED: Few studies have assessed the links of violence, desire and death with psychiatry in a scientific way. Doctors are nonetheless regularly confronted with these situations which are particularly difficult to manage. It is not evident that psychiatrists are properly prepared to deal with them. This paper proposes an original analysis of the scientific literature related to violence, desire and death, and compares the attitudes of European and American doctors. RESULTS: 1) Violence: there is definitely a relationship between violence and mental disorder. Psychiatrists are particularly at risk of being assaulted by patients, especially at the beginning of their carrier (almost 50%). Violence also includes verbal and non-verbal threats, particularly in the emergency department. Psychiatrists are poorly trained to deal with this. 2) Desire: desire is widespread in psychiatry, and can lead to sexual contact between the patient and the therapist in 7 to 10% of cases. The outpatient setting carries the greater risk. Professional associations unanimously disapprove of such conduct but the ethics of posttermination sexual contact remains controversial. Sexual harassment of female doctors by patients is another form of desire (and of violence). Psychiatrists are also poorly trained to deal with desire. 3) Death: acute death occurs in psychiatry (e.g., suicide, substance intoxication and withdrawal, delirium, neuroleptic malignant syndrome, anorexia nervosa, dementia, lethal catatonia), and there is also a link between mental disorder and a higher incidence of natural mortality. Psychiatrists may thus be confronted with death, and the inpatient setting carries the greater risk. They are nonetheless poorly trained in thanatology. DISCUSSION: Psychiatric residents need better training to manage violence, desire and death. Poor training results in their exposure to dangerous situations and in inappropriate reactions. Acute management and primary prevention are needed. Acute management should include a collegiate approach, in order to avoid being the "target" of the patient or his/her family. Primary prevention comes through the breaking of the taboos which are still too frequent in Europe, even though the situation is different from the USA. It is important to lay down limits between psychiatry and violence, desire and death. Those situations should before all be better understood, and thereby research in this field have to be stimulated. The holding of consensus conferences in Europe is also important. CONCLUSION: There is an intimate relationship between violence, desire, death and psychiatry. This relation is too often neglected, as the poor training of psychiatrists underlines. The nature of the patient-doctor relationship have to be redefined according to those considerations.

Dietary intakes and food taboos of lactating women in a South Indian community.

The diets of women, studied at regular intervals in the first year of lactation, showed that food taboos adversely affected the daily intake of energy, protein and some nutrients in the first month. Despite the poor intakes, the women breastfed their babies successfully and the weight gained by the babies in the early months was satisfactory. Breast feeding continued until the next pregnancy. Most women believed lactation prevented conception.

[Demographic consequences of genetic load: a model of the origin of the incest taboo].

The prohibition of copulations among near relatives may raise the fitness of population. This effect being irregular and insignificant for a distinct generation, becomes apparent in evolutionary time intervals through the natural selection of populations with incest-taboo. The "characteristic selection time" theta depends on typical population size, genetic damage and the mean rate of population growth. The estimation obtained for theta permit us to assert that the model describes the phenomenon of "socio-cultural selection" in prehistory. The model shows the demographic specificity of small populations. The problem of the number of consanguineous marriages is considered in detail. New explanation for deviation of the observed frequency of consanguineous marriages from classical estimations is proposed.
