The early twentieth century constituted the heyday of the ‘breadwinner–homemaker’ household, characterized by a high degree of intra-household functional specialization between paid and domestic work according to age, gender, and marital status. This article examines the links between formal workforce participation and access to resources for individualized discretionary spending in British working-class households during the late 1930s, via an analysis of household leisure expenditures. Leisure spending is particularly salient to intra-household resource allocation, as it constitutes one of the most highly prioritized areas of individualized expenditure, especially for young, single people. Using a database compiled from surviving returns to the Ministry of Labour's national 1937/8 working-class expenditure survey, we examine leisure participation rates for over 600 households, using a detailed set of commercial leisure activities together with other relevant variables. We find that the employment status of family members other than the male breadwinner was a key factor influencing their access to commercial leisure. Our analysis thus supports the view that the breadwinner–homemaker household was characterized by strong power imbalances that concentrated resources—especially for individualized expenditures—in the hands of those family members who engaged in paid labour.

The cornicle secretion of Myzus persicae reared on artificial diet only elicits an alarm response in plant-reared conspecifics after the young aphids have been transferred to plants for 7days. Acetate in the form of 0.32% sodium acetate has been added to the diet as an early step in synthesis of the alarm pheromone, (E)-β-farnesene (EBF). The cornicle secretion of diet-reared aphids then elicits an alarm response. However, there is no difference in internal EBF concentration between plant- and diet-reared aphids. Puncturing aphids, either plant- or diet-reared, with a pin shows that both can elicit an alarm response, whereas it is reduced by half with diet-reared individuals. Although there is no significant difference in the concentration of EBF produced, the total amount in diet-reared aphids is increased by acetate in the diet to a level similar to that in plant-reared individuals: the size of aphids reared on an acetate-supplemented diet is increased and comparable with the size of those that are plant-reared. Bioassays with a range of EBF concentrations show a high threshold for the alarm response. It is concluded that the different size of aphids reared on plants and standard diet results in them secreting, respectively, above and below the response threshold.

This article investigates fiscal policy responses to the Great Recession in historical perspective. We explore general trends in the frequency, size and composition of fiscal stimulus as well as the impact of government partisanship on fiscal policy outputs during the four international recessions of 1980-81, 1990-91, 2001-02 and 2008-09. Encompassing 17-23 OECD countries, our analysis calls into question the idea of a general retreat from fiscal policy activism since the early 1980s. The propensity of governments to respond to economic downturns by engaging in fiscal stimulus has increased over time and we do not observe any secular trend in the size of stimulus measures. At the same time, OECD governments have relied more on tax cuts to stimulate demand in the two recessions of the 2000s than they did in the early 1980s or early 1990s. Regarding government partisanship, we do not find any significant direct partisan effects on either the size or the composition of fiscal stimulus for any of the four recession episodes. However, the size of the welfare state conditioned the impact of government partisanship in the two recessions of the 2000s, with Left-leaning governments distinctly more prone to engage in discretionary fiscal stimulus and/or spending increases in large welfare states, but not in small welfare states.

O último mês trouxe poucas novidades sobre o desempenho e, consequentemente, sobre as perspectivas da economia brasileira para o curto prazo. Com isso, nosso cenário básico continua apresentando perspectivas mornas, com alterações marginais em relação às projeções que apresentamos no Boletim de abril. Resumidamente, estas indicam para o ano um PIB de 1,8% e uma inflação um pouco acima do teto da meta.

Ethics on scientific research is approached and often discussed in several areas of knowledge connected to health. In the Administration area there are very few studies which approach the topic of ethics on research. The present paper tried to fill in this gap in the production of knowledge about the topic, investigating how the ethical principles found in the literature and in the codes of conduct are noticed and taken into account in Administration research activities developed by acting researchers in Administration Post Graduation Programs. Theoretically speaking, the study was based mainly on the approaches by Creswell (2007) and Bell and Bryman (2007), which discuss the research ethical principles. Methodologically speaking it was all about an exploratory kind of study, with qualitative research approach. Upon data collection, personal interviews were made aiming at its depth and focus groups were formed. The first stage had interviews with four experienced researchers who took part on a teaching and researching event and on the second stage we used the focus group technique. The focus groups were done in four college institutions along with the post graduation programs in Administration in the states of Rio Grande do Norte, Paraíba and Pernambuco, in Brazil. The results suggest the existence of general principles and parameters for the scientific research recommended in the literature and on official resolution. However, in the Administration area, there are only a few recommendations of good practices when it comes to submitting articles for scientific publications but we found no guidance with ethical principles and parameters which cover all the activities in the scientific research and which specifically meet the research particularities in Administration. The main ethical dilemma pointed by the researchers refers to ethical questions which arise at the time of data collection and on disclosing the results. Most researchers do not know the guidelines and the ethical norms on ethics about research that we have in our country neither do they send in their projects to the research ethics committee. When dilemma arises, they decide the ethical question based on their values and common sense. These elements confirm the thesis that the researcher s procedure in the research activities in Administration is predominantly signed by personal values or by common sense and less by ethical principles, whether by not knowing the normative instruments related to ethics or by disagreeing with any disciplining rules on ethical behavior in the research

Endocrine disruption, in particular disruption by estrogen-active compounds, has been identified as an important ecotoxicological hazard in the aquatic environment. Research on the impact of endocrine disrupting compounds (EDCs) on wildlife has focused on disturbances of the reproductive system. However, there is increasing evidence that EDCs affect a variety of physiological systems other than the reproductive system. Here, we discuss if EDCs may be able to affect the immune system of fish, as this would have direct implications for individual fitness and population growth. Evidence suggesting an immunomodulatory role of estrogens in fish comes from the following findings: (a) estrogen receptors are expressed in piscine immune organs, (b) immune gene expression is modulated by estrogen exposure, and (c) pathogen susceptibility of fish increases under estrogen exposure.

To cite this article: Schroeder V, Kohler HP. New developments in the area of factor XIII. J Thromb Haemost 2013; 11: 234-44. Summary.  Coagulation factor (F)XIII is best known for its role in fibrin stabilization and cross-linking of antifibrinolytic proteins to the fibrin clot. From patients with congenital FXIII deficiency, it is known that FXIII also has important functions in wound healing and maintaining pregnancy. Over the last decade more and more research groups with different backgrounds have studied FXIII and have unveiled putative novel functions for FXIII. FXIII, with its unique role as a transglutaminase among the other serine protease coagulation factors, is now recognized as a multifunctional protein involved in regulatory mechanisms and construction and repair processes beyond hemostasis with possible implications in many areas of medicine. The aim of this review was to give an overview of exciting novel findings and to highlight the remarkable diversity of functions attributed to FXIII. Of course, more research into the underlying mechanisms and (patho-)physiological relevance of the many described functions of FXIII is needed. It will be exciting to observe future developments in this area and to see if and how these interesting findings may be translated into clinical practice in the future.
