Two-dimensional balanced sampling plans excluding contiguous units

A balanced sampling plan excluding contiguous units (or BSEC for short) was first introduced by Hedayat, Rao and Stufken in 1988. These designs can be used for survey sampling when the units are arranged in one-dimensional ordering and the contiguous units in this ordering provide similar information. In this paper, we generalize the concept of a BSEC to the two-dimensional situation and give constructions of two-dimensional BSECs with block size 3. The existence problem is completely solved in the case where lambda = 1.

Predictors of cheating behavior at a university: A lesson from the psychology of work

The present study investigated students' behavior across academic departments to establish how personality, demographic, educational, attitudinal, and climate (both psychological and departmental) predicted self-reported cheating behavior at a university, Participants were 107 students from a variety of academic disciplines, The results explain 50.5% of the variability in self-reported cheating behavior in terms of demographic (male, school education qualifications), departmental climate, and individual differences (Lie and Neuroticism scales), We concluded that an expanded theoretical perspective (utilizing a wide range of person and situation variables) explained more variability than would otherwise be explained from any single perspective, and that findings from the literature of integrity at work generalize to educational settings. Finally, we discuss the limitations and implications of this research.

Motherhood plans among young Australian women - Who Wants children these days?

Fertility rates in the developed world have been below replacement level for 25 years, and it is often assumed that this results from deliberate, unconstrained individual choice. Data from 7448 childless women aged 22 to 27, participating in the Australian Longitudinal Study on Women's Health, indicate that 9 per cent aspire to childlessness, with 72 per cent wanting I or 2 children and 19 per cent more. Differences in psychological functioning disappear after adjustment for socioeconomic variables. Women wanting 1 or 2 children also want paid work, while those wanting many children generally have traditional aspirations. Policy-makers need to consider strategies that support women to negotiate motherhood and paid work.
