Effects of the Interaction Between Reaction Component of Personal Need for Structure and Role Perceptions on Employee Attitudes in Long-Term Care for Elderly People

This study examined the interaction of reaction component of personal need for structure (reaction to lack of structure, RLS) and role perceptions in predicting job satisfaction, job involvement, affective commitment, and occupational identity among employees working in long-term care for elderly people. High-RLS employees experienced more role conflict, had less job satisfaction, and experienced lower levels of occupational identity than did low-RLS employees. We found individual differences in how problems in roles affected employees' job attitudes. High-RLS employees experienced lower levels of job satisfaction, job involvement, and affective commitment, irrespective of role-conflict levels. Low-RLS employees experienced detrimental job attitudes only if role-conflict levels were high. Our results suggest that high-RLS people benefit less from low levels of experienced role conflicts.

Do multinationals really prefer to enter culturally distant countries through greenfields rather than through acquisitions? The role of parent experience and subsidiary autonomy.

Prior research has argued that multinational enterprises (MNEs) prefer to enter culturally distant countries through greenfields rather than through acquisitions, since acquisitions in such countries are costlier to manage. This argument contains two hidden assumptions: (1) the additional costs of acquisitions in culturally distant countries are the same for all MNEs; and (2) such acquisitions have no benefits over their greenfield counterparts. In this paper we relax these two assumptions by arguing that an MNE's preference for greenfields in culturally distant countries depends on its international and host-country experience, and on the level of autonomy it plans to grant the focal subsidiary. Analyzing 171 wholly owned greenfield investments and full acquisitions made by Dutch MNEs in 35 countries, we find that these MNEs prefer to enter culturally distant countries through greenfields, but that this preference is lower when they have little international experience, or plan to grant the focal subsidiary considerable autonomy in marketing.

First report of the use of a saxitoxin-protein conjugate to develop a DNA aptamer to a small molecule toxin

Saxitoxin (STX) is a low molecular weight neurotoxin mainly produced by certain marine dinoflagellates that, along with its family of similarly related paralytic shellfish toxins, may cause the potentially fatal intoxication known as paralytic shellfish poisoning. Illness and fatality rates are low due to the effective monitoring programs that determine when toxins exceed the established regulatory action level and effectuate shellfish harvesting closures accordingly. Such monitoring programs rely on the ability to rapidly screen large volumes of samples. Many of the screening assays currently available employ antibodies or live animals. This research focused on developing an analytical recognition element that would eliminate the challenges associated with the limited availability of antibodies and the use of animals. Here we report the discovery of a DNA aptamer that targets STX. Concentration-dependent and selective binding of the aptamer to STX was determined using a surface plasmon resonance sensor. Not only does this work represent the first reported aptamer to STX, but also the first aptamer to any marine biotoxin. A novel strategy of using a toxin-protein conjugate for DNA aptamer selection was successfully implemented to overcome the challenges associated with aptamer selection to small molecules. Taking advantage of such an approach could lead to increased diversity and accessibility of aptamers to low molecular weight toxins, which could then be incorporated as analytical recognition elements in diagnostic assays for foodborne toxin detection. The selected STX aptamer sequence is provided here, making it available to any investigator for use in assay development for the detection of STX.

Managing state-owned enterprises in an age of crisis:An analysis of irish experience

As with all aspects of public management, the control, financing, and regulation of state-owned enterprises (SOEs) are matters subject to changing international trends and domestic political imperatives. The effects of the global financial crisis (GFC) on the ownership, financing, and role of SOEs are still unfolding, but undoubtedly will be heavily influenced by a new era of public sector reforms principally designed to reassert central political controls, as well as by fiscal pressures to balance state budgets. In this regard, the Irish experience is instructive, with the findings from two datasets being used here to examine various modes of state enterprise control and their corresponding autonomy. Significantly, there has been considerable variety within and across the SOE sector, demonstrating the need for more detailed understanding of how SOEs are managed. © 2011 Taylor & Francis.

Primary irsi stromal cyst:A report of 17 cases

Objective: To describe clinical characteristics, management, and complications of primary iris stromal cysts. Design: A retrospective review. Results: Seventeen consecutive patients with primary iris stromal cysts were found. Nine (52%) patients were diagnosed under age 10 years (range, 1 day-7 years), and eight (47%) patients were diagnosed after age 10 years (range, 14-71 years). Overall, the cyst appeared unilaterally as a solitary clear translucent mass dissecting the iris stroma in all cases. The children with a primary iris stromal cyst demonstrated a more aggressive course than teenagers or adults. In children, the cyst obstructed the visual axis in eight cases (88%), requiring treatment such as aspiration, cryotherapy, and resection. In seven children, multiple treatments were necessary. Ultimate control of the cyst was achieved in all cases using techniques of needle aspiration (with or without cryotherapy) in three cases and using resection in five cases. Primary iris stromal cysts in teenagers and adults necessitated intervention in only two cases (25%). Conclusion: Primary iris stromal cysts can occur in children, teenagers, and adults. In children, primary stromal iris cysts appear to have a more aggressive clinical course, often requiring several treatments for globe and vision preservation.
