Gender differences in first-year College students’ academic expectations

Based on a multidimensional definition of academic expectations (AEs), the authors examine students’ AE component scores across countries and genders. Two samples (343 Portuguese and 358 Spanish students) completed the Academic Perceptions Questionnaire (APQ) six months after enrolling in their universities. Factorial invariance was ensured across countries and genders, allowing us to study AEs using the APQ for both genders and in both countries. No significant differences in factor means were found between countries, indicating that AEs are not an obstacle to student mobility. Gender differences were found in some AE factor means, Training for employment, Personal and social development, Student mobility, Political engagement and citizenship, and Social pressure, with males exhibiting higher scores. Because these differences are not supported by most literature in this domain, further studies are needed to clarify the causes of women’s lower expectations and, therefore, risk of adaptation difficulties.

Evolução da população do fungo nematófago Pochonia chlamydosporia -isolado PcMR, após inoculação, no solo e na raiz do tomateiro cultivado em estufa

O fungo Pochonia chlamydospoia é um potencial agente de controlo biológico dos nemátodes-das-galhas-radiculares. Com este trabalho, pretendeu-se avaliar a eficácia de inoculações de clamidósporos no solo, no estabelecimento de uma população do fungo no solo e na raiz de tomateiro em estufa com níveis de densidade iguais ou superiores aos considerados como necessários para um eficaz controlo dos nematodes-das-galhas-radiculares. Ao longo de dois anos de ensaio, fórum efetuadas inoculações do isolado PcMR e avaliada a densidade de fungo no solo e na raiz, As inoculações efetuadas permitiram estabelecer uma população de P. chlamydosporia no solo e atingir os valores de densidade pretendidos. No entanto, os valores pretendidos para colonização da raiz pelo fungo foram atingidos apenas no primeiro ano. Foi igualmente demonstrada a capacidade do fungo em se manter no solo durante longos períodos de tempo mesmo na ausência de cultura e em condições adversas de humidade e temperatura. /ABSTRACT: Pochonia chlamydosporia is a potential root-knot nematode biological control agent. The aim of this work was to evaluate the effectiveness of chlamydospore inoculations at the soil, for the establishment at both soil and greenhouse tomato root, of a fungus population in density levels equal or superior to those considered as needed for an effective control of root-knot nematode. Along two years, several inoculations using the Portuguese isolate PcMR were made and the density of fungus at the soil and roots studied. These inoculations allowed the establishment of a population of P. chlamydosporia at the soil and achieve the desired density values. However, only in the first year of assay, the desired values of root colonization by fungus were achieved. lt was also demonstrated that P. chlamydosporia can survive for itself at the soil for a long period of time even in the absence of plant culture and in adverse moist and temperature conditions.
