OBJECTIVES Ambulance workers are regularly exposed to call-outs, which are potentially psychologically traumatic. The ability to remain objective and make adaptive appraisals during call-outs may be beneficial to this at-risk population. This pilot study investigated the links between cognitive appraisals, objectivity and coping in ambulance workers. METHODS Forty-five ambulance workers from ...

Cardiac conduction is mediated by gap junction channels that are formed by connexin (Cx) protein subunits. The connexin family of proteins consists of more than 20 members varying in their biophysical properties and ability to combine with other connexins into heteromeric gap junction channels. The mammalian heart shows regional differences both in connexin expression profile and in degree of e...

OBJECTIVE To characterize the impact of widespread inventory management policies on stock-outs of essential drugs in Zambia's health clinics and develop related recommendations. METHODS Daily clinic storeroom stock levels of artemether-lumefantrine (AL) products in 2009-2010 were captured in 145 facilities through photography and manual transcription of paper forms, then used to determine his...

Precise control of the mitotic cell cycle is a critical feature of eukaryotic life. In humans, mutations in cell cycle regulatory genes lead to the uncontrolled cell proliferation and tumor formation associated with the most dreaded of all diseases, cancer. E2F transcription factors are key components of an elaborate mechanism of cell cycle control in higher eukaryotes. For example, the promote...

A useful tool for distributed systems development is a time-outs manager. A time-outs manager is a software system that manages lists of “timeouts,” that is, objects that postpone a certain function call by a given amount of time. This feature may prove to be useful, as it allows transforming time-based events into nontime-based ones. A typical example is a time-out that on expiring sends an al...

Design of structures needs to cater to key requirements of safety and weight. To achieve these requirements, smooth flow of stresses and optimum factor of safety at all points in the structure are necessary. However, presence of cut outs becomes a necessary feature in the structures which obstruct the flow of stresses and there will be local concentration of stresses near the cut outs which nee...

This article presents an analysis of study loss in a three year longitudinal study of 1816 employees at two Danish shipyards, one of which closed just before the start of the study. The aim of the study was to elucidate the health consequences of a company closedown and the subsequent job loss. The study population responded to an identical questionnaire in 1983, 1984 and 1985. The participatio...

Virus takes the actin express V iruses typically hitchhike around the cytoplasm on microtubules. Ohkawa et al. reveal that one type of virus can travel within the cell using actin fi laments. Once baculoviruses break into a cell, they need a lift to the nucleus so their genetic material can be copied. However, these viruses don’t require microtubules for the journey. Ohkawa et al. investigated ...

This research applies data mining techniques to give a picture of the interaction of performance variables such as between stock-outs and store attributes, and stock-outs and other variables including store sales, income and demographic data, as well as various aspects of inventory management data. This research uses three data mining techniques: multiple ordinary-least-squares (OLS) regression...

The existence of two distinct visual pathways in the primate brain is a persistent theme for evolutionary, neurophysiological, motor control and neuropsychological research. As one of the most widely cited results in cognitive neuroscience, this distinction has survived decades of critical analysis under different guises (e.g. ambient vs. focal or visuomotor vs. cognitive). However, the interpl...
