The effects of gender segregation at the establishment level: an empirical analysis using a panel of matched employer-employee data

This paper studies the relationship between segregation of women across establish- ments and the wages of males and females. To investigate this issue empirically we use a panel of matched employer-employee data from Brazil. Various longitudinal models are used to assess the wage impact of establishment gender segregation. Overall, the results indicate that the e ect of establishment female proportion on the wages of males and females is negative. We also compare these longitudinal results with cross-section estimates, which are the usual ones obtained in the related literature. This com- parison suggests that unmeasured, time-invariant worker- and establishment-speci c e ects are correlated with the establishment female composition.

Cyclicality of SME Lending and Government Involvement in Banks

Recent regulatory efforts aim at lowering the cyclicality of bank lending because of its potential detrimental effects on financial stability and the real economy. We investigate the cyclicality of SME lending by local banks with vs. without a public mandate, controlling for location, size, loan maturity, funding structure, liquidity, profitability, and credit demand-side factors. The public mandate is set by local governments and stipulates a deviation from strict profit maximization and a sustainable provision of financial services to local customers. We find that banks with a public mandate are 25 percent less cyclical than other local banks. The result is credit supply-side driven and especially strong for savings banks with high liquidity and stable deposit funding. Our findings have implications for the banking structure, financial stability and the finance-growth nexus in a local context.

Which strategies can an educational business, such as a kindergarten in Germany, develop to foster employee engagement?

Which strategies can an educational business, such as a Kindergarten in Germany, develop to foster employee engagement? The goal of this master thesis is to identify effective and viable measures to engage employees, that could be potentially implemented in a Kindergarten in Germany. The literature concerning the notion of employee engagement is so inconsistent that even studies about the subject fail to find one common definition and have to acknowledge the variety of existing definitions (IES, 2014, p.52-53). This reflects the youth of the concept, which has only been partially studied by academics and practitioners in recent years. The literature gap about employee engagement concerns many aspects, among which small companies and educational businesses, in particular those focusing on early child development. Considering the low levels of employee engagement in Germany combined with the absence of studies on educational organizations focusing in early child development this master thesis studies engagement in German Kindergärten(s). This master thesis is divided in two parts consisting of a literature review and a case study. The literature review allows to follow the evolution of the concept along the years, while the case study focuses on assessing employee engagement in Montessori Kindergärten(s) in Munich & elaborating potential measures to increase engagement levels. Double sided research was undertaken for this case study. On the one hand a quantitative research was performed, through a survey, in order to uncover which strategies would be viable to foster employee engagement. On the other hand a qualitative research was undertaken, consisting in an internship in a Kindergarten, in order to shed light on how to do so. Findings in the quantitative research indicate overall engagement levels average to low. Results related to specific statements bring out the originality of the educational sector, which is in some aspects intrinsically engaging, similarly to the medical field (Seijts & Crim, 2006). Furthermore low engagement levels led to a conversely high number of positives responses to potential engagement strategies suggesting their potential effectiveness. Findings in the qualitative research are coherent with qualitative results and complement them

Um estudo exploratório sobre a Employee Value Proposition (EVP) no mercado de seguros brasileiro

As práticas da gestão de recursos humanos acompanham a evolução na gestão do capital humano das organizações. As atividades de marketing voltadas à marca corporativa prestam serviço essencial e estratégico na identificação, formatação e divulgação da marca do empregador. Juntas as duas áreas passam a desempenhar papel solidário na atração de profissionais qualificados, reforçando e propagando a identidade corporativa aos potenciais candidatos através da EVP. A EVP, a Marca do Empregador e a Reputação do Empregador se relacionam através das práticas de recrutamento e seleção, que é área de RH que primeiro mantem contato com os potenciais candidatos e inicia a construção do contrato psicológico com o novo empregado. A marca do empregador, como a imagem da organização, é utilizada para atrair, reter e engajar as pessoas e tem a EVP como seu núcleo central. Neste estudo se identifica a prática de recrutamento e seleção como a principal conexão teórica entre a EVP, a marca do empregador e a reputação do empregador e se identifica que oportunidade como a dimensão da EVP mais relevantes para o público estudado.

Involvement of serotoninergic receptors in the anteroventral preoptic region on hypoxia-induced hypothermia

Hypoxia causes a regulated decrease in body temperature (Tb). There is circumstantial evidence that the neurotransmitter serotonin (5-HT) in the anteroventral preoptic region (AVPO) mediates this response. However, which 5-HT receptor(s) is (are) involved in this response has not been assessed. Thus, we investigated the participation of the 5-HT receptors (5-HT(1), 5-HT(2), and 5-HT(7)) in the AVPO in hypoxic hypothermia. To this end, Tb of conscious Wistar rats was monitored by biotelemetry before and after intra-AVPO microinjection of methysergide (a 5-HT(1) and 5-HT(2) receptor antagonist, 0.2 and 2 mu g/100 nL), WAY-100635 (a 5-HT(1A) receptor antagonist, 0.3 and 3 mu g/100 nL), and SB-269970 (a 5-HT(7) receptor antagonist, 0.4 and 4 mu/100 nL), followed by 60 min of hypoxia exposure (7% O(2)). During the experiments, the mean chamber temperature was 24.6 +/- 0.7 degrees C (mean +/- SE) and the mean room temperature was 23.5 +/- 0.8 degrees C (mean +/- SE). Intra-AVPO microinjection of vehicle or 5-HT antagonists did not change Tb during normoxic conditions. Exposure of rats to 7% of inspired oxygen evoked typical hypoxia-induced hypothermia after vehicle microinjection, which was not affected by both doses of methysergide. However, WAY-100635 and SB-269970 treatment attenuated the drop in Tb in response to hypoxia. The effect was more pronounced with the 5-HT7 antagonist since both doses (0.4 and 4 mu g/0.1 mu L) were capable of attenuating the hypothermic response. As to the 5-HT(1A) antagonist, the attenuation of hypoxia-induced hypothermia was only observed at the higher dose. Therefore, the present results are consistent with the notion that 5-HT acts on both 5-HT(1A) and 5-HT7 receptors in the AVPO to induce hypothermia, during hypoxia.

Cultura organizacional e desempenho dos colaboradores :um estudo exploratório no setor hoteleiro

This work focuses on the relationship between organizational culture and quality culture in the hotel sector of NATAL/RN with respect to employee performance. The themes organizational culture and quality have been the research focus of administration theorists and a constant concern of professional managers, since the Japanese demonstrated effective forms or western management. In this study, the Competing Values Model (C.V.M.) (Quinn e Cameron, 1996; Quinn, 1998; Santos, 1998, 2000; Teixeira, 2001), which was tested on north-American organizations and considered a high value academic and professional instrument, was applied. The model maps the organizational culture on a profile with four elements: clan, adhocracy, market and hierarchy. The C.V.M., associated with the taximetrics created by Cameron (which classifies quality culture in for levels: status quo, error detection, error prevention and perpetual creative quality) has been related with organizational performance. In this study, these two models are used jointly and tested in the hotel sector. The results indicate that the strongest element of the profile is clan, which is characterized by internal focus, participation and people involvement, followed by the adhocracy element, which has an external focus, emphasizes flexibility and is characterized by dynamic enterprising and creativity. Regarding the level of the culture s quality in the hotel, the highest level, that of perpetual improvement and creativity, which attempts to enchant and to surprise the clients, was most frequently cited, followed by the error detection level, which has as its goal to discover and correct mistakes, trying, consequently, to reduce waste. The results suggest that employee performance as measured on some indicators is related to elements of the organizational culture profile and quality level

Involvement of nitric oxide in the gastroprotective effects of an aqueous extract of Pfaffia glomerata (Spreng) Pedersen, Amaranthaceae, in rats

The plants belonging to Pfaffia genus are used in folk medicine to treat gastric disturbances. This study examined the effects of an aqueous extract of Pfaffia glomerata (Spreng) Pedersen (AEP) on the gastrointestinal tract. Wistar rats were pretreated orally (p.o.) with the AEP (125, 250, 500 and 1000 mg.kg(-1)) before induction of ulcers by hypothermic restraint stress (HRS, 3 h restraint stress at 4 degreesC), ethanol (ET, 70%; 0.5 ml/animal; p.o.) or indomethacin (IND, 20 mg.kg(-1); s.c.). Control animals received water (C) or ranitidine (60 mg.kg(-1)) p.o. The AEP protected rats against HRS and ET-induced ulcers, but was not able to protect the gastric mucosa against IND-induced ulcers. When injected into the duodenal lumen, the AEP reduced total acidity and both basal and histamine-stimulated acid secretion in pylorus-ligated rats. In addition, gastric secretion from AEP-treated animals exhibited increased concentrations of nitrite and nitrate. Treatment of animals with L-NAME (120 mg.kg(-1), p.o.) prevented both the reduction of total acidity and the increase in NO, levels promoted by AEP treatment. In conclusion, AEP effectively protected the gastric mucosa and inhibited gastric acid secretion in rats, probably by involving the histaminergic pathway and an enhanced production of nitric oxide in the stomach.

Sex Trade Involvement in São Paulo, Brazil and Toronto, Canada: Narratives of Social Exclusion and Fragmented Identities

An extensive international literature has been developed regarding the risk trajectories of sex trade-involved children and youth. This literature has not, however, substantially incorporated the narratives of youths regarding their experiences. In this article, the contemporary literature on child and youth sex trade-involvement is reviewed and the findings of a qualitative analysis of the narratives of 14 youth from São Paulo, Brazil and 58 youth from Toronto, Canada are presented. Substantial similarities were found between the groups of narratives with respect to abusive and unstable home experiences, pathways into the sex trade, social exclusion, and the impacts of the sex trade on physical and mental health. Key areas of divergence included the roles of poverty and drug use in entering the sex trade. The implications of shared experiences of social exclusion and fragmented identity across differing sociocultural contexts for policy and intervention are discussed.

Structural modeling and mutational analysis of yeast eukaryotic translation initiation factor 5A reveal new critical residues and reinforce its involvement in protein synthesis

Eukaryotic translation initiation factor 5A (eIF5A) is a protein that is highly conserved and essential for cell viability. This factor is the only protein known to contain the unique and essential amino acid residue hypusine. This work focused on the structural and functional characterization of Saccharomyces cerevisiae eIF5A. The tertiary structure of yeast eIF5A was modeled based on the structure of its Leishmania mexicana homologue and this model was used to predict the structural localization of new site-directed and randomly generated mutations. Most of the 40 new mutants exhibited phenotypes that resulted from eIF-5A protein-folding defects. Our data provided evidence that the C-terminal alpha-helix present in yeast eIF5A is an essential structural element, whereas the eIF5A N-terminal 10 amino acid extension not present in archaeal eIF5A homologs, is not. Moreover, the mutants containing substitutions at or in the vicinity of the hypusine modification site displayed nonviable or temperature-sensitive phenotypes and were defective in hypusine modification. Interestingly, two of the temperature-sensitive strains produced stable mutant eIF5A proteins - eIF5A(K56A) and eIF5A(Q22H,L93F)- and showed defects in protein synthesis at the restrictive temperature. Our data revealed important structural features of eIF5A that are required for its vital role in cell viability and underscored an essential function of eIF5A in the translation step of gene expression.

Sporothrix schenckii lipid inhibits macrophage phagocytosis: Involvement of nitric oxide and tumour necrosis factor-alpha

The role of cell-wall compounds in the immune response to sporotrichosis is unknown. The effect of cell-wall compounds and exoantigen obtained from Sporothrix schenckii in macrophage/fungus interaction was analysed with respect to nitric oxide (NO) and tumour necrosis factor-alpha (TNF-alpha). The lipid compound of the cell wall plays an important role in the pathogenesis of this mycosis and was found to inhibit the phagocytic process and to induce high liberation of NO and TNF-alpha in macrophage cultures in the present study. This is a very interesting result because it is the first report about one compound of the fungus S. schenckii that presents this activity.

Involvement of the midbrain periaqueductal gray 5-HT1A receptors in social conflict induced analgesia in mice

Recent results from our laboratory have shown that 30-bites social conflict in mice produces a high-intensity, short-term analgesia which is attenuated by systemically injected 5-HT1A receptor agonists, such as BAY R 1531 (6-methoxy-4-(di-n-propylamino)-1,3,4,5-tetrahydrobenz(c,d)indole hydrochloride) and gepirone. The present study investigated the effects of these drugs, as well as the 5-HT1A receptor antagonist WAY 100135 (N-tert-butyl-3-(4-(2-methoxyphenyl)piperazine-1-yl)-2-phenylpropanamide) injected into the midbrain periaqueductal gray matter of mice on 30-bites analgesia. Four to five days after guide-cannula implantation, each mouse received microinjection of gepirone (30 nmol/0.2 mu l), BAY R 1531 (10 nmol/0.2 mu l), WAY 100135 (10 nmol/0.2 mu l), saline (0.9% NaCl) or vehicle (saline + 4% Tween 80) 5 min before either an aggressive (30 bites) or a non-aggressive interaction. Nociception was assessed by the tail-flick test made before as well as 1, 5, 10 and 20 min after social interaction. The full 5-HT1A receptor agonist BAY R 1531 blocked, whereas, WAY 100135 and gepirone intensified 30-bites analgesia, Neither non-aggressive interaction, per se, nor the three compounds given after this type of social interaction significantly changed nociception. These results indicate that 5-HT1A receptors in the periaqueductal gray inhibit analgesia induced by social conflict in mice. (C) 1998 Elsevier B.V. B.V.
