Spatial statistics has a rich tradition in earth, economic, and epidemiological sciences and has potential to affect the study of couples as well. When applied to couple data, spatial statistics can model within‐ and between‐couple differences with results that are readily accessible for researchers and clinicians. This article offers a primer in using spatial statistics as a methodological tool for analyzing dyadic data. The article will introduce spatial approaches, review data structure required for spatial analysis, available software, and examples of data output.  相似文献

We investigate use of empirical and exponential empirical likelihood, and Hotelling and James statistics, to test the null hypothesis of equal population means based on two independent samples of data on the simplex. We perform an extensive numerical study using data simulated from various distributions on the simplex. The results, taken together with practical considerations regarding implementation, support the use of bootstrap-calibrated James statistic.  相似文献

Problem

Although the World Health Organization and American Academy of Pediatrics recommend exclusive breastfeeding for the first six months, only 22% of U.S. mothers do so. Mothers’ perceived insufficient milk (PIM) is the primary reason for breastfeeding discontinuation globally. There are two changeable causes of PIM: (1) mothers’ misinterpretation of their infant’s behavior, and (2) mothers’ lack of confidence in their ability to breastfeed.

Aim

The purpose of this study was to evaluate the short-term effect of a home-based intervention designed to prevent and/or reduce PIM.

Methods

A mixed-methods, single-group, pretest-midtest-posttest design was used for evaluating a home-based breastfeeding program. The program was implemented during three 1.0- to 1.5-h home intervention sessions at 6, 13, and 27 days postpartum, delivered to 14 dyads of breastfeeding mothers and their full-term singleton infants.

Findings

We found significant increases over time in mothers’ sensitivity to infant behavior and breastfeeding self-efficacy as well as significant decreased attribution of infant crying to PIM. Exit interviews indicated that the program was accepted by participating mothers.

Discussion

This is the first intervention study that has directly targeted the causes of PIM. The home-based intervention has the potential to add to maternal competencies both in correctly assessing their infants’ behavior, thereby preventing erroneous attribution of infant behavior to PIM, as well as simultaneously bolstering maternal confidence in breastfeeding skills.

Conclusion

By building maternal competencies, the home-based intervention has a longer-range potential to prevent breastfeeding discontinuation. Further evaluation is warranted.  相似文献

It has been noted that adolescents may be more susceptible to pathological gambling. Not only is it usually illegal, but it appears to be related to high levels of problem gambling and other delinquent activities such as illicit drug taking and alcohol abuse. This paper examines risk factors not only in adolescent gambling but also in videogame playing (which shares many similarities with gambling). There appear to be three main forms of adolescent gambling that have been widely researched. Adolescent gambling activities and general risk factors in adolescent gambling are provided. As well, the influence of technology on adolescents in the form of both videogames and the Internet are examined. It is argued that technologically advanced forms of gambling may be highly appealing to adolescents.  相似文献

PERT techniques logically arrange all related tasks involved in completing a major process. Tasks can be examined in relationship to each other and one can determine whether—and, if so, by how much—changes in the length of time to perform one task affect overall completion time. When applied to the export process, PERT techniques allow one to examine trade-offs between alternatives such as air and water shipping; and to calculate values of accelerating each task.  相似文献

Many of the cost functions associated with depot location algorithms assume an overall demand for a fixed period, usually one year. This paper describes an investigation into the effect of high seasonality within such demand figures on the optimal location of storage facilities. The preliminary results indicate that a more flexible approach for certain products could be worthwhile.  相似文献

In an ecosystem of management journals dominated by US heavyweights, the British Journal of Management (BJM) assumes a unique role. There is no other European business and management journal of the standing and stature of this journal that seeks both to be multidisciplinary and to appeal to a general readership of business and management scholars. This is a tribute to the efforts of previous editorial teams. At the same time, the journal faces the challenge of remaining relevant both to the immediate British Academy of Management community and to the wider scholarly one, while raising its own game in pioneering and leading debates, and in global esteem.  相似文献

Against the backdrop of several concerning reports which have noted growing socio-religious conservatism and intolerance amongst Indonesia youth, this study examined how school-aged Indonesian young people navigate encounters with religious difference in their everyday lives. Recognising the significance of religious and citizenship education curricula, the research included classroom observations and interviews with 20 religiously-diverse Indonesian young people in three purposively selected high schools in Jakarta. The paper reveals that participants in all three schools agreed that religious studies and their personal religious frameworks were central to their approaches toward religious tolerance. However, their lived everyday experiences of rubbing shoulders with religious ‘others’, expanded upon and critiqued the narrowness and rigidity of these frameworks and showed greater religious inclusivity. Through this analysis the paper integrates prior work on ‘lived religion’ and ‘lived citizenship’ to fuse a ‘lived religious citizenship’ concept, arguing that this adds depth to both fields by recognising that religion cannot be separated from the experience of being a citizen. A focus on lived religious citizenship provides a deeper account of individual identity and highlights the importance of qualitative studies focused on the living out of religion and citizenship.  相似文献
