Determinants of Receptivity Towards Entomophagy among Young Adults

This research focuses on understanding the factors influencing the acceptance of entomophagy in Morelia, Michoacán. The study involves a survey aimed at two distinct groups of young adults aged 18 to 29 (control and experimental), a demographic known for being open to evolving food preferences. The results revealed interesting differences in preferences between individuals who have and have not tried insect-based foods. Surprisingly, the price did not emerge as a dominant influencing factor. The study suggests entomophagy can be a viable and accepted dietary option when relevant information is easily accessible, potentially reducing neophobia levels.

111. LIF REGULATION OF EPITHELIAL CELL FUCOSYLTRANSFERASE EXPRESSION IN MOUSE ENDOMETRIUM DURING EARLY PREGNANCY

Fucosyltransferase (FUT) enzymes are key regulators of glycosylated structures mediating embryo attachment to uterine epithelial cells at implantation. The identity of local regulatory signals is unknown. We have previously shown that macrophage co-culture significantly increases epithelial cell FUT2 and FUT4 mRNA expression in vitro, and the effect of co-culture is replicated with macrophage conditioned media. We aimed to define the identity of macrophage-secreted agents active in regulating FUT expression in mouse uterine epithelial cells, and to investigate the importance of macrophages for FUT expression in vivo. FUT1, FUT2, and FUT4 mRNAs were measured by qRT-PCR and data was normalised to β-actin mRNA in mouse uterine epithelial cells after culture with cytokines known to be secreted by macrophages. mRNA was also quantified in luminal epithelium laser-microdissected from mouse uterus on day 4 after mating with intact males or seminal vesicle deficient (SVX) males, to induce normal or depleted uterine macrophage populations respectively. Lectin staining on day 4 pc was quantified using ImageJ software in an alternate model of transient, systemic macrophage ablation following diphtheria toxin administration to CD11b-DTR transgenic mice. Epithelial FUT2 mRNA expression was specifically enhanced in vitro by addition of rLIF (2 ng/ml) (mean relative expression ± SEM, control 100 ± 5.6; rLIF 162.1 ± 11.5). Depletion of macrophages by mating with seminal vesicle deficient males reduced epithelial FUT2 mRNA expression on day 4 pc (intact 100 ± 9.1; SVX 73.5 ± 8.6). Depletion of macrophages in the CD11b-DTR mouse model caused a 30% reduction in the expression of the resulting glycoprotein epitope (α1,2 fucose) as observed by intensity of endometrial epithelial UEA-1 staining (control 100 ± 10; CD11b-DTR 72 ± 9) 24 hr post diphtheria toxin administration. In conclusion, these data demonstrate that endometrial epithelial FUT2 mRNA synthesis in preparation for embryo implantation is mediated via LIF and potentially other factors secreted from macrophages recruited during the inflammatory response to insemination. Uterine macrophage abundance and phenotype may thus be a determinant of receptivity to implantation.

Determinants of Receptivity to Expatriate Assignment

This study is an empirical investigation of receptivity to expatriate assignment in culturally similar and dissimilar environments. The theoretical underpinnings of the study emerge from a model of the expatriate adjustment process which views the determinants as anticipatory adjustment variables antecedent to actual adjustment. Vertical individualism, career distance and corporate career policy along with role clarity and economic development as moderators were found to significantly explain willingness to relocate to culturally similar environments. Economic development, corporate family policy and career distance were significant predictors of mobility to culturally dissimilar environments. The proposed model for culturally similar environments substantially improves explanatory power over an existing model. Implications of the study in conjunction with predictors from the domestic mobility and international adjustment literature are discussed.

POSSIBLE DETERMINANTS OF TEACHER RECEPTIVITY TO EVALUATION

This paper summarizes two exploratory case studies of teachers' perceptions about their receptivity to evaluation and about possible determinants of this receptivity. The first study explores relationships of receptivity to teacher controllability of evaluated behaviors. It surveys perceptions of elementary school teachers and suggests the existence of a strong positive relationship in activities associated with motivating students. The study also offers a discussion of the significance of controllability as a possible determinant of receptivity. The second study extends the investigation of the relationship between receptivity and controllability. It surveys perceptions of secondary school teachers. Specifically, it explores relationships between receptivity and controllability over two kinds of decision: those associated with teaching activities and those associated with evaluation of these activities. The study also explores the effect on the above relationships of trust and confidence which teachers have in the expertise of their evaluators. The former two relationships are found to be positive. The first, but not the second, is found to be affected by trust and confidence. Selected implications of the findings are offered.
