An important step in the statistical problem-solving process is the selection of the appropriate statistical procedure for the real-world situation under analysis. A decision-tree term project has been found to be an effective teaching device to help MBA students understand this step. The project requires the students to construct a decision-tree structure, which, through a series of questions and responses, will lead from the statement of a statistical question to the appropriate sampling distribution to use in addressing the question.  相似文献

Abstract

The author, a professor in the field of communication, describes his contrasting experiences with publishing an open access society journal and advising a regional association in regards to turning over publication of its journal to a major commercial publishing firm. Using his experience of producing an open access journal as a foundation, he argues for the intrinsic importance of establishing credibility and exercising personal care in the production and maintenance of a journal. The author argues that current efforts by some societies to increase access to their journals through outsourcing to commercial publishers may be counterproductive to the fundamental goal of disseminating knowledge.  相似文献

Couples' cognitions about marriage and their communication patterns have both been found to be highly associated with marital distress. To examine the relationships among marital cognitions, communication, and marital adjustment, we had a sample of 387 community couples complete three self-report measures: the Dyadic Adjustment Scale, the Inventory of Specific Relationship Standards, and the Communication Patterns Questionnaire. Results indicated that the correlation of communication with marital adjustment is higher for women with more relationship-focused standards than for women with less relationship-focused standards; this interaction does not occur for men. The implications of the interaction and the gender difference as well as the importance of teaching communication skills, and working with associated cognitions are discussed.  相似文献

从高本汉最早的著作开始就把中国音韵学和方言田野调查紧密地结合起来。在中古音的构拟和间接的上古音研究方面,方言资料是相当重要的角色。早期的方言田野调查以字音为主,后来认识到俗传词才是探索方言历史的关键。  相似文献

Age-specific rates of particular disability types are important for planning purposes and are a valuable input to estimates and projections of populations with different disabilities. However, survey estimates of schedules of disability rates display evidence of sampling variability and sub-national disability schedules are often unavailable for reasons of disclosure protection. This paper develops and evaluates a method to smooth sampling variability in national schedules of disability using a technique that has applicability to sub-national estimation of age-specific disability rates. Relational models are used to adjust the limiting long-term illness schedule for England (Census 2001) to represent different disability schedules (Health Survey for England 2000/2001) smoothing sampling fluctuations. For hearing disability a simple Brass relational model involving two parameters provides a good fit. For other disability types a modified version of the Ewbank relational model with three parameters is required. This paper illustrates that relational models can accurately capture the relationship between age-specific rates of limiting long-term illness and various disability types.  相似文献

By the year 2030, it is projected that one in every three Americans will be 55-years-old or older. This age group is by far thefastest growing segment of the population. With the growing number of older adults, the importance of understanding aging and common disorders of laterlife is essential. In particular, anxiety anddepression are among the most common problems in older adults. However, differentiating anxiety and depression at the mood, symptom, and syndromal levels has been a long-standing problem in psychopathology research. In addition to a growing need for research, clinicians will also need to take an active role in the development and implementation of treatment as the population of older adults increases. In particular, mental health service providers must become informed about the economic implications for older adults as the structure of health insurance continues to change.  相似文献

Most research on human sexuality has focused on long-term pairbonds and one-night stands. However, growing evidence suggests there are relationships that do not fit cleanly into either of those categories. One of these relationships is a “booty-call relationship.” The purpose of this study was to describe the sexual and emotional nature of booty-call relationships by (a) examining the types of emotional and sexual acts involved in booty-call relationships and (b) comparing the frequency of those acts in booty-call relationships to one-night stands and serious long-term relationships. In addition, the manner in which sociosexuality is associated with the commission of these acts was also examined. Demonstrative of booty-call relationships’ sexual nature was individuals’ tendency to leave after sex and infrequent handholding. In contrast, the romantic nature of booty-call relationships was demonstrated through the frequency of acts like kissing. The results suggest the booty-call relationship is a distinct type of relationship situated between one-night stands and serious romantic relationships.  相似文献
