Women and the University Presidency: Increasing Equity in Leadership

Women remain underrepresented in university presidential positions (American Council on Education, 2017). In this narrative study, eight women presidents of Carnegie Classified public doctoral granting universities were interviewed to understand how they navigated a routeto the position. Findings indicate that perceptions of gender,and opportunities for professional development, complicated the presidential path for women. Also, building leadership capacity was noted as important to sustaining and increasing women leaders in higher education

Cosmic anisotropy with Reduced Relativistic Gas

The dynamics of cosmological anisotropies is investigated for Bianchi type I universe filled by a relativistic matter represented by the reduced relativistic gas model (RRG), with equation of state interpolating between radiation and matter. Previously it was shown that the interpolation is observed in the background cosmological solutions for homogeneous and isotropic universe and also for the linear cosmological perturbations. We extend the application of RRG to the Bianchi type I anisotropic model and find that the solutions evolve to the isotropic universe with the pressureless matter contents.Comment: 18 pages, 4 figures.

Piloting VAKE (Values and Knowledge Education) in the Education for Practice of Nurses.

Imagine the following situation: You are a nurse for elderly people, going to the homes of your patients. A female patient tells you on our first visit after hospital discharge following a hip fracture surgery that she does not want to be at home, because she is not well enough to be alone and she needs therapy with oxygen in permanent basis until she recovers from a respiratory temporary infection situa¬tion. This kind of situations is the starting point for an educational sequence that ad-dresses both values (here: life, human dignity, respect, loneliness) and knowledge (different medical treatments, legal rules, etc.). The example shows how intensely interrelated the values and the facts are. Based on this example we introduce the constructivist didactical tool VaKE (Values and Knowledge Education) that permits to combine both issues, and present a pilot study using this method in the education of nurses.Tempus/LLAF; VAKEinfo:eu-repo/semantics/publishedVersio

The Demographic Transition and the Sexual Division of Labor

This paper presents a theory where increases in female labor force participation and reductions in the gender wage-gap are generated as part of a single process of demographic transition, characterized by reductions in mortality and fertility. The paper suggests a link between changes in mortality and transformations in the role of women in society that has not been identified before in the literature. Mortality reductions affect the incentives of individuals to invest in human capital and to have children. Particularly, gains in adult longevity reduce fertility, increase investments in market human capital, increase female labor force participation, and reduce the wage differential between men and women. Child mortality reductions, though reducing fertility, do not generate this same pattern of changes. The model reconciles the increase in female labor market participation with the timing of age-specific mortality reductions observed during the demographic transition. It generates changes in fertility, labor market attachment, and the gender wage-gap as part of a single process of social transformation, triggered by reductions in mortality.

Effects of selenium supplementation on cattle anti-rabies humoral immune response and levels of serum selenium and cortisol

This study evaluated the effect of different concentrations of selenium (Se) supplementation on cattle anti-rabies humoral immune response, serum Se concentrations and cortisol levels. Sixty uncastrated male Nelore calves from 10 to 12 months grazing on Brachiaria decumbens forage were studied. The animals were assigned to one of four groups (n = 15 each), which received non-supplemented diets (Gc) or supplemented with daily and individual Selenium ( Se) concentrations of 3.6 mg (G(3.6)), 5.4 mg (G(5.4)) or 6.4 mg (G(6.4)). The calves were immunized on day 0 with one dose of commercial liquid inactivated rabies vaccination. on days 15, 30, 60, 90 and 120, the cattle underwent the same stressing procedures used for vaccination in the corral. Cattle blood samples were collected after vaccination and stressing procedures to determine serum Se levels, rabies antibody titers and serum cortisol. Se levels were also determined in forage samples collected from the paddocks in which the cattle were held. Se concentration in B. decumbens was 0.04 mg of Se/kg dry matter. Baseline Se levels obtained on day 0 were higher in Gc than in G(5.4) and G(6.4) (P = 0.005). Serum Se levels decreased in Gc throughout the experiment (P < 0.004), increased in G(3.6) (P < 0.000) and G(5.4) (P < 0.000) and were kept high from day 60 on in group G(6.4) (P < 0.002). Rabies antibody titers did not differ among control and supplemented groups. However, 120 days after vaccination rabies antibody titers were kept above protective levels (>= 0.5 UI/mL) only in group G(3.6) (P < 0.00002), whereas they dropped in the other groups (P < 0.05). Serum cortisol levels did not differ among the experimental groups (P = 0.79), reached peak levels on day 90 and returned close to baseline levels on day 120. Se and cortisol levels were not markedly correlated. Serum cortisol and rabies antibody titers were correlated only in group G(6.4), on day 60 (R = 0.513; P = 0.05) and 120 (R = 0.644; P = 0.009). Serum Se and rabies antibody titers were correlated only in group G(6.4), on day 60 (R = -0.580; P = 0.023). In conclusion: a) the profile of Se variation is different among groups receiving different concentrations of this element; b) the supplementation dosage of 3.6 mg Se/animal/day is efficient to treat/prevent marginal Se deficiency; c) individual supplementation with daily concentrations of 3.6 mg Se enhances the maintenance of rabies antibody titers in cattle; d) individual supplementation with daily concentrations of 3.6; 5.4 and 6.4 mg Se are ineffective in reducing serum cortisol; e) repeated cattle handling in corrals stress animals that adapt to these procedures, although serum cortisol does not return to baseline levels by 120 days; and f) the stress generated by repeated management in cattle in the corral does not diminish antibody titers after vaccination against rabies

Biologia e potencial de Doru luteipes no controle de Spodoptera frugiperda.

0 trabalho foi realizado no Centro Nacional de Pesquisa de Milho c Sorgo (CNPMS), em Sete Lagoas, MG, tendo como objetivo conhecer a biologia e o potencial de Doru luteipes (Scudder, 1876) como predador de ovos e larvas do Spodoptera frugiperda (J.E. Smith, 1797), em condições de laboratório. Estudou-se também, em condições do campo, o efeito do diversos inseticidas sobre o predador. Dos estudos bioecológicos, observou-se que as posturas possuem, em média, 26,6 ovos, e o período de incubação é do 7,31 dias. A fase ninfal variou de 37,1 a 50,1 dias, conforme o tratamento, e a fase adulta, de 83,2 dias para individuos alimentados com ovos, a 143 dias para individuos alimentados com larvas. 0 inseto mostrou urn bom potencial como predador de S. frugiperda, apresentando um consumo diário na fase ninfal de 12, 10 e 8 larvas, conforme estas foram oferecidas isoladamente, com folhas do milho ou com dieta. Na fase adulta, o consumo foi na mesma sequência da anterior, de 21, 19 e 10 larvas. Com relação aos inseticidas testados, os produtos permethrin, deltamethrin e methomyl foram eficientes no controle de S. frugiperda, e praticamente não afetaram o predador. Com base nos resultados, conclue-se que D. luteipes, em condições do laboratório, apresentou-se eficiente no controle de S. frugiperda e possui grande potencial para utilizado no controle deste inseto em milho, em condições do campo
