Selected AbstractsA CRITICAL EXAMINATION OF THE SUITABILITY AND LIMITATIONS OF PSYCHOLOGICAL TESTS IN FAMILY COURTFAMILY COURT REVIEW, Issue 2 2007Steven K. Erickson Psychologists are frequently consulted by the courts to provide forensic evaluations in a variety of family court proceedings. As part of their evaluations, psychologists often use psychological tests to assess parents, guardians, and children. These tests can have profound effects on how psychologists arrive at their opinions and are often cited in their reports to the court. However, psychological tests vary substantially in their suitability for these purposes. Most projective tests in particular appear to possess little scientific merit for evaluations within family court proceedings. Despite these serious limitations, expert testimony derived from evaluations using both projective and objective tests is often admitted uncontested. This article reviews the psychometric properties of psychological tests that are widely used in family court proceedings, cautions against their unfettered use, and calls upon attorneys to inform themselves of the limitations of evaluations that incorporate these tests. [source] The Delphi technique: myths and realitiesJOURNAL OF ADVANCED NURSING, Issue 4 2003Catherine Powell BNSc PhD RGN RSCN RHV Aim.,To outline the key concepts and principles of the Delphi technique. Methods.,Reference is made to a selection of studies that illustrate a variety of methodological interpretations. Drawing on Heshusius's concept of ,goodness criteria', particular emphasis is given to the question of scientific merit and means of evaluation. Conclusion.,Although the technique should be used with caution, it appears to be an established method of harnessing the opinions of an often diverse group of experts on practice-related problems. [source] GEOMETRICAL, THERMAL AND MECHANICAL PROPERTIES OF OLIVE FRUITSJOURNAL OF FOOD PROCESS ENGINEERING, Issue 2 2010MOHAMAD I. AL-WIDYAN ABSTRACT In Mediterranean countries, olive trees play a significant economical role. Knowledge of olive fruits properties is essential for the efficient handling of the product and optimizing oil yield. The lack of such knowledge at the local level triggered this study in an attempt to report the fruit's chemical composition and some major engineering properties. Established procedures were followed in conducting the measurements and calculations on fruit samples. The study examined four major varieties of olive fruits, including Spanish, Black Spanish, improved Nabali and Nabali Baladi for their chemical composition and other properties, including geometrical, thermal and frictional properties. Thermal properties, including thermal conductivity, heat capacity and thermal diffusivity, ranged from 0.41 to 0.47 W/(m·K), 2.35 to 2.39 kJ/(kg·K) and 2.88 × 10,7to 2.779 × 10,7 m2/s, respectively. The geometrical properties of the Spanish and Black Spanish were quite similar except for roundness and sphericity. Similar results were found for improved Nabali and Nabali Baladi. The properties of weight, density and packing coefficient ranged from 2.22 to 8.60 g, 890 to 1,230 kg/m3 and 0.43 to 0.52, respectively. The fruit's static friction coefficient over mild steel, aluminum and softwood surfaces ranged from 0.20 to 0.30, 0.21 to 0.29 and 0.22 to 0.33, respectively. PRACTICAL APPLICATIONS In Jordan and other Mediterranean countries, olive fruits are produced in large quantities every season. They are very widely used as pickled fruits or are processed in mills to extract their oil. Despite the fact that fruit properties are a necessary prerequisite for the efficient handling and processing of fruits, literature search indicated the lack of a comprehensive study of scientific merit that reports on the engineering properties of olive fruits. In addition, it is established that knowledge of the fruit properties leads to optimized handling and processing and results in knowledge-based development of all processes and equipment that deal with the fruits. The practical merit of this study stems from the fact that it reports on the key properties of a major product (olive fruits) that has social, cultural and economical significance throughout a whole region and is expanding throughout the globe. [source] Effects of Obesity on PregnancyJOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 2 2008Shelia A. Smith ABSTRACT Objectives:, To examine physiologic and psychological outcomes associated with maternal obesity in pregnancy and patterns of pregnancy weight gain. To identify effective interventions for maternal obesity. Data sources and study selection:, Search of obesity and pregnancy research conducted over the past 10 years using CIHAHL, Medline ERIC, and PyscInfo databases. Studies including the following keywords were included in the review: obesity, weight gain, body image, pregnancy weight gain, pregnancy obesity complications, preeclampsia and gestational diabetes. Articles were included based on scientific merit and research outcomes. Data synthesis and conclusions:, Maternal obesity is a serious condition that significantly impacts not only mothers' health but also the health and future of their children. It is paramount that all levels of health care providers be aware of consequences of obesity and be knowledgeable of effective interventions. No effective long-term interventions have been demonstrated to prevent or control obesity during pregnancy. The paucity of published results of pregnancy and postpartum interventions to address weight gain in pregnancy suggests the need for more community and individualized based intervention studies, especially focusing on long-term effects. [source] Evaluating Acute Musculoskeletal ComplaintsJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 5 2001Mary Jo Goolsby EdD Clinical practice guidelines (CPG) are now widely available summarizing large amounts of scientific evidence and providing specific recommendations for the evaluation, diagnosis, and management of varied health problems. In order to take advantage of the available CPGs in clinical practice, providers must be aware of their existence and be able to critique them for scientific merit and relevance to specific clinical settings. This ongoing series is designed to provide a brief review of a different CPG each month. This month, the CPG reviewed addresses the evaluation of an extremely common set of complaints: musculoskeletal symptoms. The document emphasizes the importance of a thorough history and physical for these presentations and indicates when specific diagnostic studies and/or consultations are warranted. [source] Utopianism in psychology: The case of Wilhelm ReichJOURNAL OF THE HISTORY OF THE BEHAVIORAL SCIENCES, Issue 2 2002Petteri Pietikainen Ph.D. research fellowArticle first published online: 8 APR 200 This article examines utopian elements in Wilhelm Reich's writings in his American phase (1939,1957) in order to illustrate utopian sources of dynamic psychology. Although there are scholars who have used the term "psychological utopia" and applied it to individual thinkers (Reich, Marcuse, Fromm) and to specific psychological disciplines (psychoanalysis, behaviorism, cognitive psychology), the term itself has remained elusive and vague. Furthermore, there have been few attempts to systematically examine utopian elements in twentieth-century psychology in general and the basic assumptions of psychological utopianism in particular. While pointing out that Reich's orgonomic theories have no scientific merit, this article argues for the relevancy of his ideas for understanding the nature of utopianism in dynamic psychology. © 2002 Wiley Periodicals, Inc. [source] Psychosocial adjustment of siblings of children with cancer: a systematic reviewPSYCHO-ONCOLOGY, Issue 8 2010Melissa A. Alderfer Abstract Objectives: To promote a broader understanding of the psychosocial impact of childhood cancer on siblings, a systematic review was undertaken. Directions for future research are proposed and clinical strategies are suggested for addressing the needs of these children. Methods: Searches of Medline, PsycINFO and CINAHL revealed 65 relevant qualitative, quantitative, or mixed methods' papers published between 1997 and 2008. These papers were rated for scientific merit and findings were extracted for summary. Results: Siblings of children with cancer do not experience elevated mean rates of psychiatric disorders, but a significant subset experiences post-traumatic stress symptoms, negative emotional reactions (e.g. shock, fear, worry, sadness, helplessness, anger, and guilt), and poor quality of life in emotional, family, and social domains. In general, distress is greater closer to time of diagnosis. School difficulties are also evident within 2 years of diagnosis. Qualitative studies reveal family-level themes such as loss of attention and status as well as positive outcomes including increased sibling maturity and empathy. Conclusions: Research regarding siblings of children with cancer continues to be methodologically limited. The conclusions of qualitative and quantitative studies differ considerably. We propose a research agenda to propel this field forward including greater attention to alterations in normative development (as opposed to psychiatric conditions), development of more appropriate quantitative measures, examination of potential moderators of adaptation, and use of prospective longitudinal designs. Siblings of children with cancer are a psychosocially at-risk group and should be provided with appropriate supportive services. Copyright © 2009 John Wiley & Sons, Ltd. [source] PHILOSOPHY IN FRAGMENTS: CULTIVATING PHILOSOPHIC THINKING WITH THE PRESOCRATICSMETAPHILOSOPHY, Issue 5 2009DANIEL SILVERMINTZ Abstract: This article presents a strategy for introducing Presocratic thought to students in a manner that is both engaging and relevant. The first section addresses students' reactions to the claim that the Presocratics were the first philosophers. The second section considers how the fragmentary state of Presocratic thought does not hinder its comprehension. The third section proposes a classroom exercise for testing the scientific merits of each of the Presocratic theories. The final section proposes the use of a mock trial as a means of applying the materialist approach introduced by the Presocratics to contemporary debates about free will and determinism.
