Selected AbstractsDo Premarital Education Programs Really Work?FAMILY RELATIONS, Issue 3 2010A Meta-analytic Study Previous studies (J. S. Carroll & W. J. Doherty, 2003) have asserted that premarital education programs have a positive effect on program participants. Using meta-analytic methods of current best practices to look across the entire body of published and unpublished evaluation research on premarital education, we found a more complex pattern of results. We coded 47 studies and found that premarital education programs do not improve relationship quality/satisfaction when unpublished studies are included in the analysis, although studies that follow couples past the honeymoon stage to detect prevention effects are rare. In contrast, premarital education programs appear to be effective at improving couple communication, with studies that employed observational measures rather than self-report measures producing large effects. Still, given the mixed, modest results, there is ample room and a real need to improve the practice of premarital education. [source] Occurrence and life history correlates of vocal duetting in North American passerinesJOURNAL OF AVIAN BIOLOGY, Issue 1 2008Lauryn Benedict Vocal duetting, where two birds produce temporally coordinated vocalizations, has been reported in a taxonomically and geographically diverse set of avian species. Researchers have suggested a number of potential correlates of duetting, including long term monogamy, year-round territory defense and sexual plumage monomorphism. Because the majority of duetting species are tropical, they have been the focus of the most comprehensive studies to date. There is, therefore, a real need for data regarding avian duets in temperate species. I used the recently completed Birds of North America species reports to examine the frequency, evolutionary origins and potential life history correlates of duetting behavior in North American passerines. "Duetting" behavior was reported in 7% of species from 12 avian families, likely representing 17 separate evolutionary origins. Duetting species showed apparent long term monogamy and year-round territoriality at frequencies more than double those of non-duetting passerines: 65% of duetting species were long term monogamous, compared to 27% of non-duetting species, and 50% of duetting species defended the same territory throughout the year, compared with only 11% of non-duetting species. Duetting and non-duetting species showed statistically indistinguishable frequencies of sexual plumage monomorphism. Comparative analyses of duetting species and their sister taxa revealed that the shift to duetting is accompanied by a gain of long term monogamy and year-round territoriality more often than it is associated with a loss of those traits. This study provides intriguing summary evidence that selective factors promoting duetting may be associated with a sedentary, monogamous lifestyle, and may operate similarly across taxonomic groups. Furthermore, vocal duetting may be considerably more common among temperate-zone species than previously recognized. [source] Clinical (Nonforensic) Application of Ethyl Glucuronide Measurement: Are We Ready?ALCOHOLISM, Issue 6 2010Peter Jatlow Ethyl glucuronide (EtG) and ethyl sulfate (EtS) are minor metabolites of ethanol. Multiple studies have documented that, depending upon the amount of alcohol consumed, they can be measured in biological fluids for hours to days after the parent compound can no longer be detected. Testing for the presence of EtG, in a manner analogous to urinary drug abuse screening, has largely been restricted to forensic and law enforcement situations. Despite a real need for an objective and possibly quantitative marker of ethanol exposure for use in conjunction with outpatient clinical trials and treatment programs, measurement of these metabolites has seen only limited clinical application. The barriers to more extensive clinical use of EtG/EtS testing, particularly misleading assay results that can occur as a consequence of inadvertent exposure to nonbeverage ethanol-containing substances, are reviewed and put into perspective. Additional information needed to develop guidelines for optimal clinical utilization of EtG/EtS measurements is discussed. [source] The Liquidity Demand for Corporate Property InsuranceJOURNAL OF RISK AND INSURANCE, Issue 2 2006Arthur Hau This article suggests that liquidity may be an important reason for a corporation to purchase property insurance. A model of a risk-neutral producer facing an endogenously determined risk of property damage under an output contract that penalizes underproduction is formulated to exemplify such a real need of liquidity. Under the output contract, the producer may purchase full unfavorable property insurance even when postloss financing is available. Surprisingly, the conclusion may still hold when the cost of postloss financing equals that of long-term capital, provided that the rate of underproduction penalty is sufficiently high. Similar conclusions apply when postloss financing is replaced by planned internal reserve (self-insurance) that may be invested in the short run at an interest rate that is lower than the long-term cost of capital. When the capital market is perfect, however, the holding of planned internal reserve eliminates the purchase of actuarially unfavorable property insurance. [source] Managing innovation in an emerging sector: the case of marine-based nutraceuticalsR & D MANAGEMENT, Issue 4 2007Jayaram K. Sankaran Biotechnology is turning a traditionally low-tech industry (food) into a high-tech industry (functional food/nutraceuticals). There is a real need to enhance managerial understanding by clarifying the nature of innovation processes in the functional food industry, including the role of research and development (R&D) and collaboration. The present investigation focuses on a particular segment of the functional food industry, viz. marine-based nutraceuticals. We find that various hurdles thwart the fullest realization of the business potential of marine bio-actives in the pharmaceutical space. However, the innovation of commercially viable marine-based nutraceuticals/cosmeceuticals is yet possible if the extraction route for supply is a feasible fallback option, should industrial-scale synthesis prove elusive. Effectiveness in innovation is facilitated by the collaboration of various disciplines including epidemiology, traditional/folkloric medicine, aquaculture/fermentation, natural products chemistry, toxicology, and relevant strands of medical, pharmacological, and clinical research. In this regard, the inter-disciplinary field of ethno-pharmacology rises to prominence. Universities and government research institutes may be well positioned to drive such collaboration and reap the benefits from problem definition in addition to problem solving. Toward this end, the findings from the present study are integrated into a phased approach toward the innovation of commercially viable marine-based nutraceuticals that is targeted at entrepreneurs in this field. [source] Dangerous and severe parenting disorder?CHILD ABUSE REVIEW, Issue 4 2003Personality disorder, new legal proposals, parenting Abstract The Government has proposed new legal measures for the management of people with personality disorders who are dangerous to others. In this paper, it is argued that there is no reason why these proposed measures should not apply to those individuals with personality disorders who are parents and present a severe risk of harm to their own children. New measures that provided a legal and clinical framework for the provision of assessment and possible therapy for personality disordered parents who pose a risk to their children would ful,l a real need which is not being met.

Krebs First page of article [source] Adapting the logical basis of tests for Hardy-Weinberg Equilibrium to the real needs of association studies in human and medical geneticsGENETIC EPIDEMIOLOGY, Issue 7 2009Katrina A. B. Goddard Abstract The standard procedure to assess genetic equilibrium is a ,2 test of goodness-of-fit. As is the case with any statistical procedure of that type, the null hypothesis is that the distribution underlying the data is in agreement with the model. Thus, a significant result indicates incompatibility of the observed data with the model, which is clearly at variance with the aim in the majority of applications: to exclude the existence of gross violations of the equilibrium condition. In current practice, we try to avoid this basic logical difficulty by increasing the significance bound to the P -value (e.g. from 5 to 10%) and inferring compatibility of the data with Hardy Weinberg Equilibrium (HWE) from an insignificant result. Unfortunately, such direct inversion of a statistical testing procedure fails to produce a valid test of the hypothesis of interest, namely, that the data are in sufficiently good agreement with the model under which the P -value is calculated. We present a logically unflawed solution to the problem of establishing (approximate) compatibility of an observed genotype distribution with HWE. The test is available in one- and two-sided versions. For both versions, we provide tools for exact power calculation. We demonstrate the merits of the new approach through comparison with the traditional ,2 goodness-of-fit test in 2×60 genotype distributions from 43 published genetic studies of complex diseases where departure from HWE was noted in either the case or control sample. In addition, we show that the new test is useful for the analysis of genome-wide association studies. Genet. Epidemiol. 33:569,580, 2009. © 2009 Wiley-Liss, Inc. [source] Family involvement in perioperative nursing of adult patients undergoing emergency surgeryJOURNAL OF CLINICAL NURSING, Issue 2 2001Eija Paavilainen PhD ,,The purpose of this study was to describe how adult patients undergoing emergency surgery experience family centredness in perioperative nursing practice. The central aim was to generate knowledge to be used while developing the practice, education and management of perioperative nursing. ,,Data were collected using a questionnaire with emergency surgical patients in five regional hospitals in Southern Finland. The number of distributed questionnaires was 132. The response rate was 85% (n=112). ,,The results were mainly described as frequencies and percentages. The open-ended sections of the answers were analysed using qualitative content analysis. The findings from the open-ended questions were used for deepening and complementing the quantitative description of the results. ,,In the preoperative phase, ascertaining the family situation and informing the family member chosen by the patient were not achieved systematically. Family situation was also rarely examined in the intraoperative and postoperative phases, although it is central to coping after surgery, especially in home care. ,,The results support the view of earlier research about the importance of individuality of patients and their families during the perioperative care process and hence enhance the endeavour to develop nursing based on families' real needs. [source] Assessment of hidden and future customer needs in Finnish business-to-business companiesR & D MANAGEMENT, Issue 4 2001Hannu Kärkkäinen The development of new products should be based on the needs expected to exist even several years ahead , at the moment of market introduction and during the whole lifecycle of the product. To develop successful new products in the toughening business environment, companies should be able to surpass customers' expectations and to assess emerging customer needs proactively. Early, thorough understanding of the customer's real needs, including the assessment of hidden and future customer needs and requirements, plays a very important role in the successful development of new products. The purpose of our paper is to study the assessment of new (hidden and future) customer needs for product development in Finnish business-to-business companies. We have carried out a survey in 93 Finnish business-to-business companies and SBUs to study their common problems in the assessment of unrecognized customer needs and potentially effective ways in clarifying new customer needs and dealing with important problems. On the basis of the results, we propose several possible ways to facilitate the assessment of unrecognized customer needs. [source] The learning credit card: A tool for managing personal development,BRITISH JOURNAL OF EDUCATIONAL TECHNOLOGY, Issue 2 2008Nick Rushby This is the report of a five month study, undertaken by Sundridge Park Training Technologies in association with Guildford Educational Services to assess the potential of smart card technology to support learning and the management of learning. The study had two strands,the state of the art of the technology and its potential for supporting, delivering and managing learning. In addition to a study of the literature and extensive discussions with people using smart cards, potential users of smart card and visionaries, the project team developed two illustrative systems using cards to store personal data relating to education and training. The term ,smart card' is often used loosely to describe three different types of card, each of which is similar in general shape and size to a traditional credit card. These are: memory cards, laser cards,and true smart cards incorporating a processor and memory. This study has been concerned with memory cards and smart cards. The focus for smart card applications has been predominantly financial: there are relatively few applications in education or training. A notable exception is the large scale project at the University of Bologna which uses smart cards to manage the progress and achievements of a large number of students in the Department of Electronics. The two illustrative systems provided valuable experience of using memory cards and smart cards in quasi-real education and training applications. They highlighted the problems of limited memory capacities and confirmed the high level of user acceptance reported by other trials. We can expect considerable advances in the technology of both memory cards and smart cards over the next months and years. The memory capacities of both types of cards will increase many-fold and the unit costs will fall as large quantities of cards are produced for financial applications. Education and training applications will benefit from this expanding market. The major surprise from the study was the level of interest in the work and the enthusiasm expressed by almost all of those who came to hear of it. The general level of awareness of smart card technology was found to be low. However, the requirement for a system which will enable individuals to manage and own their learning on an extended timescale was generally recognised. Some of the possible applications for smart cards and memory cards in education and training had emerged before the official start of the study and it is clear that the technology is potentially pervasive. The project team and those consulted identified a wide range of possible applications both in education and in training. These focussed on assessment, personal course planning and management, identification of relevant learning opportunities, and the ownership of learning. It was felt that, over the next few years, smart cards are very likely to be in common use as credit cards for financial applications. Therefore, their use for education and training should be planned now. The recommendations from the study are that: More detailed studies are needed to find out how smart cards and memory cards could be used by different organisations in a fully operational system; Standards should be established for smart card applications in education and training, similar to those governing financial applications; Applications should be developed after the standards have been established. To be convincing, these should take a case study approach with small pilot studies in a variety of contexts and must follow real needs rather than attempt to drive them; The case studies would then form the basis for a campaign to increase awareness of smart cards and their potential for education and training, together with a programme for building an infrastructure to support the proposed systems. The public sector should fund the task of developing standards and providing interfaces with existing educational systems and projects to demonstrate the feasibility of various applications. Since educational standards have a European dimension, the European Community may be a source of support for work in the area of standards. At the same time, private sector funding should be sought for skill development and career development systems in industry and in education. The Training Agency itself should consider the application of smart card technology to the control and management of the Youth Training Scheme (YTS). [source] | |||||||||||||||||||
