Nursing performance in the policy transfer of directly observed treatment of tuberculosis

Objective Analyzing the policy transfer of directly observed treatment of tuberculosis from the perspective of nursing. Method This is a descriptive study with qualitative approach, which had 10 nurses of the Family Health Strategy in São Paulo as subjects. The interviews were carried out between May and June 2013, and were adopted the technique of thematic content analysis and the referential of policy transfer. Results On the signification of this treatment, are related the senses of disciplinary monitoring, the bond and approximation to the context of patients’ lives. Operationally, nurses, community health agents and nursing technicians stand out as agents of implementation of this policy, developing multiple actions of user embracement. The nurse is evidenced as an educator in health, leader in the family health team, and capable of creating emotional bond with users. Conclusion It was found that the innovations proposed in the treatment are incipient in the daily work of nurses.

Decision-Making in Social Enterprises: Exploring the Link between Employee Participation and Organizational Commitment

This article studies the influence of the procedural justice resulting from participation in decision-making on employees' affective commitment in social enterprises. It also examines whether any potential link between participation and commitment is due to social exchange, as is the case with for-profit companies. The study is based on data from employees of French work integration social enterprises. The results confirm the positive relationship between procedural justice and affective commitment and the mediating role of perceived organizational support and leader-member exchanges. Managerial recommendations are then given to best maintain or increase employees' involvement in the decision-making processes of social enterprises.

Aplicação da Teoria de decisão na optimização do custo de transporte público colectivo de passageiros em Mindelo - Renovar ou manter frota existente. - Estudo de caso da TRANSCOR-SV, S.A -

Com um mundo dos negócios cada vez mais dinámico, os gestores têm a necessidade de serem capazes de tomar decisões que garantam o acompanhamento dessas mudanças. Para isso, precisam ter à sua disposição um conjunto de ferramentas e técnicas de gestão de auxílio ao processo de tomada de decisão. Neste contexto, foi desenvolvido o estudo da teoria de decisão, cuja premissa é determinar o valor esperado das decisões alternativas, em situações de incerteza e risco. Tendo em conta o objetivo de verificar a viabilidade da aplicação desta teoria aos custos do transporte público colectivo de passageiros, apresentamos o estudo de caso na Transcor-SV, SA, líder do mercado em São Vicente, onde recolhemos os dados, através da aplicação de uma entrevista e documentos fornecidos pela empresa. Com estes dados, aplicámos a metodologia baseada nas teorias de decisão. With a business world increasingly dynamic, the managers need to be able to make decisions that ensure the monitoring of these changes. For this, they must have at their disposal a set of tools and management techniques to assist their making decision. In this context, we developed the study of theories of decision, whose premise is to determine the expected value of alternative decisions in situations of uncertainty and risk. Having regard to the objective of verifying the viability of the application this theory to the cost of collective public transport of passengers, we present the case study on Transcor-SV, SA, market leader in São Vicente, where we collect information through the application of an interview and documents supplied by the company. With these data, we applied the methodology based on the theories of the decision.

Endogenous price leadership

We consider a linear price setting duopoly game with di®erentiatedproducts and determine endogenously which of the players will lead andwhich will follow. While the follower role is most attractive for each firm, we show that waiting is more risky for the low cost firm so that,consequently, risk dominance considerations, as in Harsanyi and Selten(1988), allow the conclusion that only the high cost firm will choose towait. Hence, the low cost firm will emerge as the endogenous price leader.

Secreted glutamic protease rescues aspartic protease Pep deficiency in Aspergillus fumigatus during growth in acidic protein medium.

In an acidic protein medium Aspergillus fumigatus secretes an aspartic endoprotease (Pep) as well as tripeptidyl-peptidases, a prolyl-peptidase and carboxypeptidases. In addition, LC-MS/MS revealed a novel glutamic protease, AfuGprA, homologous to Aspergillus niger aspergillopepsin II. The importance of AfuGprA in protein digestion was evaluated by deletion of its encoding gene in A. fumigatus wild-type D141 and in a pepΔ mutant. Either A. fumigatus Pep or AfuGprA was shown to be necessary for fungal growth in protein medium at low pH. Exoproteolytic activity is therefore not sufficient for complete protein hydrolysis and fungal growth in a medium containing proteins as the sole nitrogen source. Pep and AfuGprA constitute a pair of endoproteases active at low pH, in analogy to A. fumigatus alkaline protease (Alp) and metalloprotease I (Mep), where at least one of these enzymes is necessary for fungal growth in protein medium at neutral pH. Heterologous expression of AfuGprA in Pichia pastoris showed that the enzyme is synthesized as a preproprotein and that the propeptide is removed through an autoproteolytic reaction at low pH to generate the mature protease. In contrast to A. niger aspergillopepsin II, AfuGprA is a single-chain protein and is structurally more similar to G1 proteases characterized in other non-Aspergillus fungi.

Vaccinia virus produces late mRNAs by discontinuous synthesis.

We describe the unusual structure of a vaccinia virus late mRNA. In these molecules, the protein-coding sequences of a major late structural polypeptide are preceded by long leader RNAs, which in some cases are thousands of nucleotides long. These sequences map to different regions of the viral genome and in one instance are separated from the late gene by more than 100 kb of DNA. Moreover, the leader sequences map either upstream or downstream of the late gene, are transcribed from either DNA strand, and are fused to the late gene coding sequence via a poly(A) stretch. This demonstrates that vaccinia virus produces late mRNAs by tagging the protein-coding sequences onto the 3' end of other RNAs.

Endogenous price leadership

We consider a linear price setting duopoly game with differentiated products and determine endogenously which of the players will lead and which will follow. While the follower role is most attractive for each firm, we show that waiting is more risky for the low cost firm so that, consequently, risk dominance considerations, as in Harsanyi and Selten (1988), allow the conclusion that only the highcost firm will choose to wait. Hence, the low cost firm will emerge as the endogenous price leader.

Country asymmetries, endogenous product choice and the speed of trade liberalization

In a world with two countries which differ in size, we study theimpact of (the speed of) trade liberalization on firms' profitsand total welfare of the countries involved. Firms correctlyanticipate the pace of trade liberalization and take it intoaccount when deciding on their product choices, which areendogenously determined at the beginning of the game. Competitionin the marketplace then occurs either on quantities or on prices.As long as the autarkic phase continues, local firms are nationalmonopolists. When trade liberalization occurs, firms compete in aninternational duopoly. We analyze trade effects by using twodifferent models of product differentiation. Across all thespecifications adopted (and independently of the price v. quantitycompetition hypothesis), total welfare always unambiguously riseswith the speed of trade liberalization: Possible losses by firmsare always outweighed by consumers' gains, which come under theform of lower prices, enlarged variety of higher average qualitiesavailable. The effect on profits depends on the type of industryanalyzed. Two results in particular seem to be worth of mention.With vertical product differentiation and fixed costs of qualityimprovements, the expected size of the market faced by the firmsdetermines the incentive to invest in quality. The longer the periodof autarky, the lower the possibility that the firm from the smallcountry would be producing the high quality and be the leader in theinternational market when it opens. On the contrary, when trade opensimmediately, national markets do not play any role and firms fromdifferent countries have the same opportunity to become the leader.Hence, immediate trade liberalization might be in the interest ofproducers in the small country. In general, the lower the size of thesmall country, the more likely its firm will gain from tradeliberalization. Losses from the small country firm can arise when itis relegated to low quality good production and the domestic marketsize is not very small. With horizontal product differentiation (thehomogeneous good case being a limit case of it when costs ofdifferentiation tend to infinity), investments in differentiationbenefit both firms in equal manner. Firms from the small country do notrun the risk of being relegated to a lower competitive position undertrade. As a result, they would never lose from it. Instead, firms fromthe large country may still incur losses from the opening of trade whenthe market expansion effect is low (i.e. when the country is very largerelative to the other).

Endogenous Stackelberg leadership

We consider a linear quantity setting duopoly game and analyzewhich of the players will commit when both players have the possibility todo so. To that end, we study a 2-stage game in which each player caneither commit to a quantity in stage 1 or wait till stage 2. We show thatcommitting is more risky for the high cost firm and that, consequently,risk dominance considerations, as in Harsanyi and Selten (1988), allowthe conclusion that only the low cost firm will choose to commit.Hence, the low cost firm will emerge as the endogenous Stackelberg leader.

Growth accounting in items of turbulence and death: efficiency, technology, capital accumulation and human capital 1929-1950

We employ a non-parametrical approach to growth accounting (Data Envelopment Analysis,DEA) to disentangle the proximate sources of labour productivity growth in 41 nationsbetween 1929 and 1950 by decomposing productivity growth into four components:technological change; efficiency catch-up (movements towards the production frontier),capital accumulation and human capital accumulation. We show that efficiency catch-upgenerally explains productivity growth, whereas technological change and factoraccumulation were limited and distorted by the effects of war. War clearly hamperedefficiency. Moreover, an unbalanced ratio of human capital to physical capital (a gap to thetechnological leader) was crucial for efficiency catching-up.

Leadership and individual differences: at the cusp of a renaissance

In this introductory editorial, we provide a brief overview of the history of individual difference research in leadership. We explain the major challenges that trait research faced, and why it was revived primarily because of methodological advancements. Next, we argue that leadership individual difference research is at a cusp of a renaissance. We explain why we are at this cusp and what researchers should do reify the renaissance in terms of theoretical extensions of trait models, the application of robust methodological advancements, and the development of process models linking distal (i.e., traits) predictors to proximal predictors (e.g., behaviors, skills, attitudes), and the latter to leader outcomes. We then summarize the papers we accepted for the special issue, and conclude with an optimistic note for leadership individual difference research.

Predictors of leadership: The usual suspects and the suspect traits

In this chapter, I review literature on traits (i.e., individual differences) and their links to leader outcomes. I present an integrated model, the ascription-actuality trait theory, to explain two routes to leader outcomes that stem from traits: the route that objectively matters and the route that appears to matter but objectively may not. I discuss the history of trait research and provide criteria by which we should judge the validity of trait models. Finally, I review trait models that are the most predictive of leadership outcomes and identify those that are non-starters.

Charting Our Own Course: Today’s Challenges, Tomorrow’s Opportunities, December 2008

The Office of Energy Independence presents Iowa’s second annual energy independence plan, which highlights accomplishments achieved thus far and makes recommendations for the coming year. This plan shows that Iowa has made significant progress in building the foundation for reaching energy independence in just the past year. Continued investment and further efforts will enable Iowa to push toward even greater advances, while creating new jobs and diversifying local economies. With those aims in mind, the state has been investing extensively in the new energy economy. One important example is the Iowa Power Fund, an annual appropriation from the Iowa General Assembly administered by the Office of Energy Independence. In less than one year, the Office has received more than 160 project applications totaling more than $308 million in requests. The projects approved thus far will help advance Iowa’s wind and solar industries, foster new energy efficiency practices, and develop the bio fuels industry for a more economically and environmentally sustainable future. Iowa’s position as a leader in the new energy economy is dependent on the success of the Power Fund, and on the success of this plan. This plan clearly states that Iowa must boldly pursue a strong position in the emerging energy economy worldwide.

Characterisation of two soluble metalloexopeptidases in the protozoan parasite Leishmania major.

Two soluble exopeptidases were identified in promastigotes of Leishmania major, using an iodinated model tetrapeptide (LIAY) as substrate. Similar activities were also detected in L. major amastigotes and in different species of Leishmania promastigotes. A carboxy- and an aminopeptidase activity were resolved and isolated by anion exchange and gel permeation chromatographies. A single polypeptide of 62 kDa co-purified with the aminopeptidase activity. Optimum pH was neutral for the carboxypeptidase and neutral to alkaline for the aminopeptidase. Both activities were able to hydrolyse a dipeptide substrate (YL), and were inhibited by 20 microM bestatin and 200 microM 1,10-phenanthroline, but not by leupeptin, iodoacetamide and a range of other inhibitors. These results strongly suggest that both enzymes are metalloexopeptidases and thus represent a novel class of soluble peptidases in Leishmania.
