A generalized neighbor design relaxes the equality condition on the number of times two treatments as neighbors in the design. In this article, we have considered the construction of some classes of generalized neighbor designs with block size k=3 by using the method of cyclic shifts. The distinguishing feature of this construction method is that the properties of a design can easily be obtained from the sets of shifts instead of constructing the actual blocks of the design. A catalog of generalized neighbor designs with block size k=3 is compiled for v∈{5,6,…,18} treatments and for different replications. We provide the reader with a simpler method of construction, and in general the catalog that gives an open choice to the experimenter for selecting any class of neighbor designs.  相似文献

Abstract

Many social workers are expected to work with individuals and families who are dealing with life-limiting illnesses, yet during their university education they may not have been exposed to materials that address issues related to death and dying. The Social Work Department of University of New England in Armidale, Australia designed and delivered a palliative care teaching and learning session using publicly funded online materials. Themes emerging from questionnaire and focus group data analysis included appreciation for the importance and emotional demands of the materials, sensitivity and flexibility among educators who ideally have work experience in the field, expanding presence of social work philosophy in curriculum materials and exploring spirituality, and examining culture-informed practice in greater depth. Among the implications is the need for concerted efforts to teach about death and dying using high quality accessible materials, while ensuring social work values and approaches are reflected in the content.  相似文献

The economic-history literature of eighteenth-century British America is rich in its quantitative measures of staple production, output prices and demography, but relatively thin in its analysis of input prices. This paper addresses one aspect of this gap by, for the first time, applying a hedonic regression technique to land sales in Britain's most important colony. The results indicate that land values increased over the course of the late eighteenth century, despite economic challenges such as the American Revolution and a series of punishing hurricanes in the 1780s. The model estimates that values reached their peak in 1800, only to decline during the first decade of the nineteenth century.  相似文献

This paper explores the developmental stages and phases of a new blended learning social work course at a rural Australian university. The background to the development of the discipline will be presented, with an exploration of the challenges and outcomes of designing an interactive online environment for a single cohort of on-campus and distance students. Themes explored cover engaging students, motivation, acculturation and facilitation. The paper concludes with the presentation of data from wave one of a longitudinal survey to ensure student expectations are being met, while at the same time providing an accredited programme of study.  相似文献

A group of 209 married, fecund women in rural Bangladesh were studied prospectively for 24 months from 1969 to 1971 to define some of the biological and sociological factors relating to fertility performance. These women were selected from a larger study population of 112,000 that had been followed with a daily house-to-house vital registration programme since 1966. The selected women were interviewed bi-weekly and were asked questions about menstruation, pregnancy, lactation, husband's occupational absences, and monthly urine tests for pregnancy were taken. The results for 193 non-contracepting women revealed that the seasonal pattern of births previously observed in this population could be associated with a corresponding seasonal pattern of conceptions and that this was due to a seasonal trend in fecundability. The highest conception rates were in the coolest months of the year. Post-partum lactational amenorrhoea was very prolonged, averaging 17 months for women with a surviving child. The appearance of the first post-partum menstrual flow (onset of ovulation) also had a seasonal trend which could not be adequately explained. The median waiting time to conception, once menstruation had resumed was eight months. This interval was influenced by seasonal fluctuations, as well as by the age of women and by husbands' absences. The foetal wastage rate was 15·0 per 100 conceptions, with 62 per cent of the foetal losses occurring during the second month of gestation. Overall, the average birth interval was 33 months, with the prolonged lactational amenorrhoea accounting for almost 45 per cent of this interval.   相似文献

Background

Perinatal mortality remains a major international problem responsible for nearly six million stillbirths and neonatal deaths.

Objectives

To estimate the perinatal mortality rate in Sana’a, Yemen and to identify risk factors for perinatal deaths.

Methods

A community-based prospective cohort study was carried out between 2015 and 2016. Nine-hundred and eighty pregnant women were identified and followed up to 7 days following birth. A multi-stage cluster sampling was used to select participants from community households’, residing in the five districts of the Sana’a City, Yemen.

Results

Total of 952 pregnant women were tracked up to 7 days after giving birth. The perinatal mortality rate, the stillbirth rate and the early neonatal mortality rate, were 89.3 per 1000, 46.2 per 1000 and 45.2 per 1000, respectively. In multivariable analysis older age (35+ years) of mothers at birth (Relative Risk = 2.83), teenage mothers’ age at first pregnancy (<18 years) (Relative Risk = 1.57), primipara mothers (Relative Risk = 1.90), multi-nuclear family (Relative Risk = 1.74), mud house (Relative Risk = 2.02), mothers who underwent female genital mutilation (Relative Risk = 2.92) and mothers who chewed khat (Relative Risk = 1.60) were factors associated with increased risk of perinatal death, whereas a positive mother’s tetanus vaccination status (Relative Risk = 0.49) were significant protective factors against perinatal deaths.

Conclusion

Rates of perinatal mortality were higher in Sana’a City compared to perinatal mortality at the national level estimated by World Health Organization. It is imperative there be sustainable interventions in order to improve the country’s maternal and newborn health.  相似文献

This paper seeks to provide empirical evidence on the efficacy of three important governance mechanisms (auditors, directors, and institutional shareholders) in constraining aggressive financial reporting, proxied by abnormal accruals. It also examines the effects of the Sarbanes–Oxley Act (SOX) on their efficacy. Using a sample of US firms audited by the Big 5 (4) auditors between 2000 and 2004, we document a positive relation between abnormal accruals (our proxy for financial reporting aggressiveness) and auditors’ economic dependence on their clients. Furthermore, we find that this relation is driven by firms with weak non-auditor governance mechanisms before and after the enactment of SOX. The results suggest that aggressive financial reporting occurs only when multiple governance mechanisms ‘fail’. More specifically, such type of reporting requires that a highly dependent auditor operates in a ‘poor’ governance setting. Thus, the paper underscores the importance of strong governance in constraining aggressive financial reporting. Moreover, our results suggest that governance regulation (such as SOX) is not a substitute for strong governance mechanisms and thus caution against the over reliance on SOX-type legislation in other parts of the world.  相似文献

Governance ensures a wide range of desirable values including efficiency, productivity, participation, transparency, and accountability. The wide scope and overambitious demands of governance make it difficult to conceptualize and operationalize. Despite huge investments in time and resources, developing countries seldom succeed in establishing good governance. Based on the experience of Hong Kong, this article argues that many of the desired values of governance can be attained through effective design and the implementation of public management reforms. Public management cannot serve as an alternative for governance, but reforms in this area can help update and adjust institutional structures, processes, and practices in developing countries; they help to ensure the benefits of the desired values of governance without undertaking enormous risks. However, the size of a country and the nature of its political system will influence the degree of success in establishing governance.  相似文献
