Toxicological and histopathological effects of hydramethylnon on Atta sexdens rubropilosa (Hymenoptera: Formicidae) workers

The leaf-cut ants are important agricultural pest, because they can cause intense defoliation in plants and destroy large areas cultivated. Although there are several works for the control of these insects by examining the toxicity of natural chemical compounds on various species of ants, few are focused on analyses of morphological changes caused in the affected organs. The aim of this study was to evaluate the effects of hydramethylnon on Atta sexdens rubropilosa workers through toxicological bioassays and morphological analysis of the post-pharyngeal glands, midgut, and Malpighian tubules of these ants. Hydramethylnon dissolved either in acetone (HA) or in a mixture of acetone and soy oil (HAO) was added to the artificial diet at a concentration of 200 μg/mL. The workers fed daily with the diet containing hydramethylnon showed higher mortality than the controls, especially when HAO was used. Moreover, light and electron microscopy revealed morphological alterations in the midgut and Malpighian tubules of workers treated with HA, whereas alterations of the post-pharyngeal glands were observed in the HAO-treated group. These results indicated that the presence of soy oil provided an alternate route for the ingestion of the formicide's active ingredient and corroborated previous studies that suggested a role for the post-pharyngeal glands in lipid metabolism. Our findings suggest that the oil may carry hydramethylnon to the gland lumen, resulting in lower quantity of the active ingredient in the intestinal lumen and Malpighian tubules that explains the lower degree of morphological alterations in these structures in the workers treated with HAO. These results may provide insight into the toxicological effects of hydramethylnon on leaf-cutting ants and the use of vegetable oil as an adjuvant in baits to control ants. © 2012 Elsevier Ltd.

A heuristic algorithm based on multi-assignment procedures for nurse scheduling

This paper tackles a Nurse Scheduling Problem which consists of generating work schedules for a set of nurses while considering their shift preferences and other requirements. The objective is to maximize the satisfaction of nurses' preferences and minimize the violation of soft constraints. This paper presents a new deterministic heuristic algorithm, called MAPA (multi-assignment problem-based algorithm), which is based on successive resolutions of the assignment problem. The algorithm has two phases: a constructive phase and an improvement phase. The constructive phase builds a full schedule by solving successive assignment problems, one for each day in the planning period. The improvement phase uses a couple of procedures that re-solve assignment problems to produce a better schedule. Given the deterministic nature of this algorithm, the same schedule is obtained each time that the algorithm is applied to the same problem instance. The performance of MAPA is benchmarked against published results for almost 250,000 instances from the NSPLib dataset. In most cases, particularly on large instances of the problem, the results produced by MAPA are better when compared to best-known solutions from the literature. The experiments reported here also show that the MAPA algorithm finds more feasible solutions compared with other algorithms in the literature, which suggest that this proposed approach is effective and robust. © 2013 Springer Science+Business Media New York.

The meaning of evidence-based management to brazilian senior nurse leaders

Purpose: The study objective was to understand the meaning of evidence-based management for senior nurse leaders in accredited, public hospitals in the State of Sao Paulo, Brazil. Design and Method: A phenomenological approach was used to analyze interviews conducted with 10 senior nurse leaders between August 2011 and March 2012. The analytic method was developed by the Brazilian phenomenologist, Martins. Findings: Senior nurse leaders described how they critically appraise many sources of evidence when making managerial decisions. They emphasized the importance of working with their teams to locally adapt and evaluate best evidence associated with managerial decision making and organizational innovations. Their statements also demonstrated how they use evidence-based management to support the adoption of evidence-based practices. They did not, however, provide specific strategies for seeking out and obtaining evidence. Notable challenges were traditional cultures and rigid bureaucracies, while major facilitators included accreditation, teamwork, and shared decision making. Conclusions: Evidence-based management necessitates a continuous process of locating, implementing, and evaluating evidence. In this study leaders provided multiple, concrete examples of all these processes except seeking out and locating evidence. They also gave examples of other leadership skills associated with successful adoption of evidence-based practice and management, particularly interdisciplinary teamwork and shared decision making. Clinical Relevance: This study demonstrates senior nurse leaders' awareness and utilization of evidence-based management. The study also suggests what aspects of evidence-based management need further development, such as more active identification of potential, new organizational innovations. © 2013 Sigma Theta Tau International.

Domestic Workers in Jamaica

This paper addresses how and why domestic workers in Jamaica are disenfranchised, with particular emphasis on the law’s inability to combat their exploitation in the labour force. My starting point is an online newspaper article entitled “Coping as a Domestic Helper”, which was based on a study investigating the living standard and coping strategies of minimum wage earners. In Jamaica domestic workers fall into three main categories - the residential worker, the non-residential weekly worker and the daily worker. Domestic workers are undervalued and their plight is especially grievous because they are characterized by a number of features that combine to have an exponentially negative effect on their social worth.
