Exercise of essential competencies for midwifery care by nurses in Sao Paulo, Brazil

General objective: to analyse the exercise of essential competencies for midwifery care by nurses and/or midwives in the public health system of Sao Paulo (eastern zone), Brazil. Specific objectives: to develop a profile of the public health institutions and of the nurses and/or midwives who care for women before, during and following child birth; to identify the activities performed in providing such care, as well as their frequency; and to specify the possible obstacles or difficulties encountered by them when exercising their competencies. Design: a descriptive and exploratory research design , using a quantitative approach. Setting: the study was conducted in all public health services of Sao Paulo (eastern zone), Brazil, namely 59 basic health-care units and six hospitals, during the period of October 2006-December 2007. Participants: the study population consisted of 272 nurses and/or midwives who provide care for pregnant women and newborns at the primary health-care units and maternity hospitals of the public health system. Participants comprised 100% of hospital nurse coordinators (n = 6), 61% of hospital maternity nursing and/or midwifery staff (n = 62) and 64% (n = 204) of nursing and/or midwifery staff working at primary health-care units. Methods and findings: the data collection was based on a single form given to the coordinators and two questionnaires, one handed out to antenatal and postnatal nursing and/or midwifery staff and another handed out to labour and birth nursing and/or midwifery staff. The results showed that nurses and/or midwives providing care for women during pregnancy, labour, birth and the postnatal period did not put the essential competencies for midwifery care into practice, because they encountered institutional barriers and personal resistance, and lacked protocols based on best practice and on the exercise of essential competencies needed for effective midwifery care. Key conclusions: the model of care in the public health services of Sao Paulo (eastern zone) is based much more on hierarchical positions than on professional competencies or on there commendations of the scientific community. As a result, health authorities need to review their midwifery policies to improve maternal-infant care by nurses and/or midwives in order to ensure the implementation of best midwifery practice. Practical implications: the results of this study support actions to improve the quality of care delivered to women and their families, while integrating nursing and midwifery care in Sao Paulo, Brazil.

Changes in inflammatory mediators following eccentric exercise of the elbow flexors

The aims of this study were to examine the plasma concentrations of inflammatory mediators including cytokines induced by a single bout of eccentric exercise and again 4 weeks later by a second bout of eccentric exercise of the same muscle group. Ten untrained male subjects performed two bouts of the eccentric exercise involving the elbow flexors (6 sets of 5 repetitions) separated by four weeks. Changes in muscle soreness, swelling, and function following exercise were compared between the bouts. Blood was sampled before, immediately after, 1 h, 3 h, 6 h, 24 h (1 d), 48 h (2 d), 72 h (3 d), 96 h (4 d) following exercise bout to measure plasma creatine kinase (CK) activity, plasma concentrations of myoglobin (Mb), interleukin (IL)-1 beta, IL-1 receptor antagonist (IL-1ra), IL-4, IL-6, IL-8, IL-10, IL-12p40, tumor necrosis factor (TNF)-alpha, granulocyte colony-stimulating factor (G-CSF), myeloperoxidase (MPO), prostaglandin E-2 (PGE(2)), heat shock protein (HSP) 60 and 70. After the first bout, muscle soreness increased significantly, and there was also significant increase in upper arm circumference; muscle function decreased and plasma CK activity and Mb concentration increased significantly. These changes were significantly smaller after the second bout compared to the first bout, indicating muscle adaptation to the repeated bouts of the eccentric exercise. Despite the evidence of greater muscle damage after the first bout, the changes in cytokines and other inflammatory mediators were quite minor, and considerably smaller than that following endurance exercise. These results suggest that eccentric exercise-induced muscle damage is not associated with the significant release of cytokines into the systemic circulation. After the first bout, plasma G-CSF concentration showed a small but significant increase, whereas TNF-alpha and IL-8 showed significant decreases compared to the pre-exercise values. After the second bout, there was a significant increase in IL-10, and a significant decrease in IL-8. In conclusion, although there was evidence of severe muscle damage after the eccentric exercise, this muscle damage was not accompanied by any large changes in plasma cytokine concentrations. The minor changes in systemic cytokine concentration found in this study might reflect more rapid clearance from the circulation, or a lack of any significant metabolic or oxidative demands during this particular mode of exercise. In relation to the adaptation to the muscle damage, the anti-inflammatory cytokine IL-10 might work as one of the underlying mechanisms of action.

On heuristic and linear models of judgment: Mapping the demand for knowledge

Research on judgment and decision making presents a confusing picture of human abilities. For example, much research has emphasized the dysfunctional aspects of judgmental heuristics, and yet, other findings suggest that these can be highly effective. A further line of research has modeled judgment as resulting from as if linear models. This paper illuminates the distinctions in these approaches by providing a common analytical framework based on the central theoretical premise that understanding human performance requires specifying how characteristics of the decision rules people use interact with the demands of the tasks they face. Our work synthesizes the analytical tools of lens model research with novel methodology developed to specify the effectiveness of heuristics in different environments and allows direct comparisons between the different approaches. We illustrate with both theoretical analyses and simulations. We further link our results to the empirical literature by a meta-analysis of lens model studies and estimate both human andheuristic performance in the same tasks. Our results highlight the trade-off betweenlinear models and heuristics. Whereas the former are cognitively demanding, the latterare simple to use. However, they require knowledge and thus maps of when andwhich heuristic to employ.

The conclusion of the deduction of taste in the dialectic of the power of judgment aesthetic in Kant

In this paper, it is argued that only in the section on dialectic in the Critique of Judgment does Kant reach a definitive and conclusive version of deduction, after discovering the concept of the supersensible. In the section on the deduction of pure aesthetic judgments, Kant does not satisfactorily explain the critical distinction between the sensible nature of humanity and the supersensible nature of human reason presupposed in the concept of universal communicability. While the concept of the supersensible illustrates this distinction, it is only through this concept that Kant that can justify the specific possibility of claiming subjective validity in taste. The priority of the solution found in the dialectic is illustrated not only by a comparative analysis of the two sections, but also by a historical reconstruction of the process of the formation of the work, which shows that the first formulation of the concept of validity coincides with the use of the concept of the supersensible.

The community museum: a space for the exercise of communal power

This paper discusses two key elements in the field of museums: a summary of the concept of the community museum, on the one hand, and, on the other, a proposal as to how this concept is put into practice, especially in the early stages of the creation of the museum, when the social basis for the project is being established. We will discuss how the community museum combines and integrates complex processes aimed at strengthening the community as a collective subject, asserting its identity, improving its quality of life and building alliances between communities. In the second part, which has a methodological focus, we will discuss how the museum is born out of community aspirations to strengthen its identity and integrity, the initial process of consensus-building, the roles of different agents, both internal and external to the community, as well as some factors that foster or prevent community appropriation. To conclude we will emphasize the potential of community museum networks as a strategy to generate a broader field of action, in which communities can exercise greater autonomy, by collectively developing and appropriating projects of regional and even international scope.

Cognitive Comparative Advantage and the Organization of Work: Lessons from Herbert Simon's Vision of the Future

In a marvelous but somewhat neglected paper, 'The Corporation: Will It Be Managed by Machines?' Herbert Simon articulated from the perspective of 1960 his vision of what we now call the New Economy the machine-aided system of production and management of the late twentieth century. Simon's analysis sprang from what I term the principle of cognitive comparative advantage: one has to understand the quite different cognitive structures of humans and machines (including computers) in order to explain and predict the tasks to which each will be most suited. Perhaps unlike Simon's better-known predictions about progress in artificial intelligence research, the predictions of this 1960 article hold up remarkably well and continue to offer important insights. In what follows I attempt to tell a coherent story about the evolution of machines and the division of labor between humans and machines. Although inspired by Simon's 1960 paper, I weave many other strands into the tapestry, from classical discussions of the division of labor to present-day evolutionary psychology. The basic conclusion is that, with growth in the extent of the market, we should see humans 'crowded into' tasks that call for the kinds of cognition for which humans have been equipped by biological evolution. These human cognitive abilities range from the exercise of judgment in situations of ambiguity and surprise to more mundane abilities in spatio-temporal perception and locomotion. Conversely, we should see machines 'crowded into' tasks with a well-defined structure. This conclusion is not based (merely) on a claim that machines, including computers, are specialized idiots-savants today because of the limits (whether temporary or permanent) of artificial intelligence; rather, it rests on a claim that, for what are broadly 'economic' reasons, it will continue to make economic sense to create machines that are idiots-savants.

A costing exercise of provision of prevention of HIV transmission from mother to child services in Vietnam

Objectives. This dissertation focuses on estimating the cost of providing a minimum package of prevention of mother-to-child HIV transmission (PMTCT) in Vietnam from a societal perspective and discussing the issues of scaling-up the minimum package nationwide. ^ Methods. Through collection of cost-related data of PMTCT services at 22 PMTCT sites in 5 provinces (Hanoi, Quang Ninh, Thai Nguyen, Hochiminh City, and An Giang) in Vietnam, the research investigates the item cost of each service in minimum PMTCT packages and the actual cost per PMTCT site at different organizational levels including central, provincial, and district. Next, the actual cost per site at each organizational level is standardized by adjusting for HIV prevalence rate to arrive at standardized costs per site. This study then uses the standardized costs per site to project, by different scenarios, the total cost to scale-up the PMTCT program in Vietnam. ^ Results. The cost for HIV tests, infant formula, and salary of health workers are consistently found to be the biggest expenditures in the PMTCT minimum package program across all organizational levels. Annual cost for drugs for prophylaxis treatment, operating and capital, and training costs are not substantial (less than 5% of total costs at all levels). The actual annual estimated cost for a PMTCT site at the central level is nearly VND 1.9 billion or US$ 107,650 (exchange rate US$ 1 = VND 17,500) while the annual cost for a provincial site is VND 375 million or US$ 21,400. The annual cost for a district site is VND 139 million (∼US$ 8,000). ^ The estimated total annual cost to roll out the PMTCT minimum package to the 5 studied provinces is approximately US$ 1.1 million. If the PMTCT program is to be scaled-up to 14 provinces until 2008 and up to 40 provinces through the end of 2010 as planned by the Ministry of Health, it would cost the health system an approximate annual amount of US$ 2.1 million and US$ 5.04 million, respectively. The annual cost for scaling-up the PMTCT minimum package nationwide is around US$ 7.6 million. Meanwhile, the total annual cost to implement PMTCT minimum packages to achieve PMTCT national targets in 2010 (providing counseling service to 90% of all pregnant women; 60% of them will receive HIV tests and 100% of HIV (+) mother and their newborn will receive prophylaxis treatment) would be US$ 6.1 million. ^ Recommendations. This study recommends: (1) the Ministry of Health of Vietnam should adjust its short-term national targets to a more feasible and achievable level given the current level of available resources; (2) a detailed budget for scaling-up the PMTCT program should be developed together with the national PMTCT action plan; (3) the PMTCT scaling-up plan developed by the Ministry of Health should focus on coverage of high prevalence population and quality of services provided rather than number of physical provinces reached; (4) exclusive breastfeeding strategy should be promoted as part of the PMTCT program; and (5) for a smooth and effective rolling out of PMTCT services nationwide, development of a national training plan and execution of this plan must precede any other initiations of the PMTCT scaling-up plan. ^
