The role of values in the scientific process is widely debated. But evidence and values cannot be neatly separated. Instead, values infuse the entire scientific process, starting with the choice of research questions. Research avenues are selected based on prior beliefs about the workings of the world. In fact, informally assigned prior probabilities and normalizing constants play an essential role in distinguishing causes from correlations and ignoring irrelevant associations that would otherwise be suggested by raw data. But since these initial probabilities often have a heterogeneous pedigree – often not all that went into their formation is known or knowable – it becomes difficult to cleanly separate evidence from values. At the same time, this reality does not undermine science’s unique status in generating knowledge. This is because it is not the evidence per se generated by science, but rather the method by which science generates it, that justifies science’s privileged role.  相似文献

Socioculturally influenced interpretations of mental illness play decisive roles on the time and choice of treatment. These often result in significant delays before patients present at the psychiatric services, with consequent worsening of the prognosis. The aim was to assess the association between sociocultural factors, choice of treatment and treatment delay among patients with schizophrenia. A cross-sectional study of 360 patients with schizophrenia, without previous contact with any statutory psychiatric services, was done. Of this, 75.8% of the participants had visited traditional/faith healers as the first treatment option and have attributed schizophrenia to magico-supernatural causation, despite 70.0% of the participants being educated, while 24.2% of them believed in the natural causation of the illness and presented early to psychiatric hospital. There is a need for community-based psychiatric services that would have mental health education as one of their core mandates; and collaborations with traditional and faith-based healers aimed to reduce delay in their facilities.  相似文献

Substantial investments in health-care have ensured the widespread availability of allopathic medical services across the United Arab Emirates (UAE). However, in spite of this accessibility traditional healers (Mutawa) continue to play a significant, albeit, unofficial role in the UAE's health sector. Citizens routinely consult traditional healers for problems that might, from a western biomedical perspective, be considered psychiatric conditions. This qualitative study explores traditional healers' conceptualisations of mental health problems, discussing their perspectives on phenomenology, aetiology, intervention and outcome. Notably, traditional healers distinguished between biomedical illness and states they attributed to demonological or metaphysical causes. The Islamic spiritual narrative was central to discussions of aetiology, intervention and outcome. Greater integration of traditional healers within the UAE's mental health-care services would, in many cases, improve patient experience and outcomes.  相似文献

This article presents information on the development and initial validation of the 16-item Response to Intervention (RTI) Beliefs Scale. The scale is designed to measure the extent to which educators working in schools hold beliefs consistent with the tenets of RTI. The authors administered the instrument to 2,430 educators in 62 elementary schools in the fall of 2007 and 2,443 educators in 68 elementary schools in the spring of 2008. Exploratory, single-level confirmatory, and multilevel confirmatory factor analysis procedures were used to examine construct validity. Results supported a correlated 3-factor model (Academic Abilities and Performance of Students with Disabilities, Data-Based Decision Making, and Functions of Core and Supplemental Instruction) at both the school and educator levels of analysis. Furthermore, the factor scores derived from the model demonstrated significant, positive relations to RTI implementation. Reliability estimates for two of the three factor scores exceeded.70. Implications for research on educator beliefs and implementation of RTI as well as implications for school psychologists supporting RTI implementation are discussed.  相似文献

This study aimed to explore health professionals' views and practice regarding the provision of information about health-protective behaviors (e.g., exercise, alcohol consumption, diet) during genetic consultation for breast cancer. Ten genetic counselors participated in three focus groups, and seven medical specialists were interviewed in a focus group or individually. Data was analyzed using the constant comparative method. Findings suggested that health professionals held differing, often opposing, views about the value of health-protective behaviors for women at increased risk of breast cancer. The content and extent of information provided about health-protective behaviors varied widely, and participants expressed a need to form consensus regarding information provision both within and across clinics. The main barriers to providing information regarding health-protective behaviors included the lack of research evidence regarding the impact of these factors and higher priority of other information need to be provided in the limited consultation time. Participants generally did not consider it their role to promote health-protective behaviors, and were concerned about the psychological impact of providing information about behavioral risk factors during genetic consultations.  相似文献

Social and ethical dimensions of nanoscale science and engineering research   总被引:1,自引:0,他引:1  
Continuing advances in human ability to manipulate matter at the atomic and molecular levels (i.e. nanoscale science and engineering) offer many previously unimagined possibilities for scientific discovery and technological development. Paralleling these advances in the various science and engineering subdisciplines is the increasing realization that a number of associated social, ethical, environmental, economic and legal dimensions also need to be explored. An important component of such exploration entails the identification and analysis of the ways in which current and prospective researchers in these fields conceptualize these dimensions of their work. Within the context of a National Science Foundation funded Research Experiences for Undergraduates (REU) program in nanomaterials processing and characterization at the University of Central Florida (2002–2004), here I present for discussion (i) details of a “nanotechnology ethics” seminar series developed specifically for students participating in the program, and (ii) an analysis of students’ and participating research faculty’s perspectives concerning social and ethical issues associated with nanotechnology research. I conclude with a brief discussion of implications presented by these issues for general scientific literacy and public science education policy.  相似文献

Abstract: Since the 1982 publication of Aldo Carotenuto's book, A Secret Symmetry: Sabina Spielrein Between Jung and Freud, there has been renewed interest in the life and work of Sabina Spielrein. She was Jung's first psychoanalytic case at the Burghölzli Hospital in 1904, and was referred to several times in The Freud/Jung Letters. Spielrein recovered, enrolled in medical school, and went on to become a Freudian analyst. Her most famous paper, published in 1912, ‘Destruction as a cause of coming into being’, was referred to by Freud in 1920 in relation to his Death Instinct theory. In the few Freudian publications on this controversial theory since 1920, Spielrein's contribution is consistently omitted. Jung also neglected to refer to her ‘Destruction’ paper in his early 1912 version of ‘Symbols of transformation’, even though he had edited her paper and had promised to acknowledge her contribution. He did refer extensively to Spielrein's first paper, her medical thesis, ‘On the psychological content of a case of schizophrenia’, published in 1911, as yet unpublished in English. In her paper Spielrein sought to understand the psychotic delusions of Frau M, a patient at the Burghölzli, much in the style of Jung's ‘Psychology of dementia praecox’ (1907). The purpose of this paper is to explore to what extent Spielrein's Frau M paper, and its companion ‘Destruction’ paper, make an original contribution to both Jung and Freud's emerging theories on the possible creative versus destructive outcomes of neurotic or psychotic introversion, culminating in Jung's concept of the ‘collective unconscious’ (1916) and Freud's concept of a ‘Death instinct’ (1920).  相似文献

Investigated whether three self-system beliefs, fear of abandonment, coping efficacy, and self-esteem, mediated the relations of stressors and caregiver–child relationship quality with concurrent and prospective internalizing and externalizing problems in a sample of children who had experienced parental death in the previous 2.5 years. The cross-sectional sample consisted of 340 children ages 7–16 and their surviving parent/current caregiver; the longitudinal analyses employed a subset of this sample that consisted of 100 children and their parents/caregivers who were assessed at three time points. A multirater, multimethod measure of caregiver–child relationship quality and a multirater measure of children's mental health problems were used. The cross-sectional model supported a mediational relation for fear of abandonment, coping efficacy, and self-esteem. The three-wave longitudinal model showed that fear of abandonment at Time 2 mediated the relation between stressors at Time 1 and internalizing and externalizing problems at Time 3. Implications of these findings for understanding the development of mental health problems in parentally bereaved children and designing interventions for this at-risk group are discussed.

In many communities, supplying water and sanitation is a huge task, and the fact that these essential services can be carried out by the private sector is a debated issue. This article presents an exploratory study aimed to identify the range of motives for collective action shared by activists of the Italian Movement for ‘Public Water’. In‐depth interviews were conducted with 28 activists and were qualitatively analysed. Five main motivational categories emerged: defending the right to water, preserving community ties, opposing to the Government and ‘water sellers’, preserving the environment and money interests. Each motive is based on a specific representation of the issue of water and privatization process. Findings provide further support for the importance of moral convictions and sense of community in collective action development and suggest a critical reconsideration of the role played by collective efficacy. The results are discussed in the framework of the psychosocial literature on collective action and community psychology perspectives on participatory processes.
