Postgraduate boundary crossings?

This Special Issue: Crossing Philosophical, Cultural and Geographic Boundaries in Educational Scholarship?: Postgraduate Experiences arose out of an invited panel of postgraduate speakers at the 42nd Philosophy of Education Society of Australasia Conference, held 7–10 December 2012 in Chiayi, Taiwan. The wider conference theme of “Crossing Boundaries” generated lively discussions about what such encounters and experiences might mean in the broader sphere of education; while the postgraduate speakers were invited to address their personal experience of boundaries during doctoral study. The central thrust of this invitation was to consider the extent to which such boundaries could (or should) be crossed through postgraduate experiences, and to gain a deeper appreciation of what this might mean for scholars who venture – physically and/or philosophically – outside of familiar terrain. The papers that comprise this issue provide associated cross-cultural, cross-country and cross-philosophical narratives, reflections and interrogations of their experiences in this regard. In doing so the authors provide a rich landscape through which to consider boundary crossing as an opportunity to expand on knowledge and/or to appreciate ones own position through encounters with ‘other’. Such crossings (or attempts to cross) presented significant challenges to these students, as they reveal in this issue. Their insights highlight the point that crossing philosophical, cultural and geographic boundaries is often a difficult relationship between all three, and, that there are costs involved. Such profoundly confronting experiences of crossing (or not crossing) are not necessarily bridges to be traversed as much as a means of confronting boundaries through which students might gain important insights – about themselves as persons of culture, scholars and members of a global society that is characterized by difference. This complex encounter – for all its pleasure and pain – is, evident through every paper in this issue, and sets the scene for important 21st century dialogues concerning diversity and difference in education

Communicating Across Cultures

[Excerpt] Communication is the key to so many things a steward does, and good communication skills are something experienced stewards develop. But even experienced stewards have special challenges when the communication is between people of different cultures

Implicit Motives Across Cultures

In recent years, methodological and substantial progress has been made in the field of cross-cultural studies on implicit motives. We propose that cross-cultural studies on implicit motives are indispensable to understand universal and culture-specific variations in individuals’ mental processes and behavior. It is assumed that implicit motives represent the first motivational system to be shaped in a human being’s ontogeny and that they have far-reaching consequences for individuals’ development, their feelings and actions in everyday life across different cultural groups. Applying psychometrically sound measurements cross-culturally, researchers have revealed a number of universal relationships between implicit motives and psychological and behavioral correlates. Despite these promising advancements, fundamental work still needs to be done with respect to the developmental antecedents of motives and behavioral correlates, particularly focusing on affiliation and power, which have received much less attention compared to the achievement motive. We conclude that if we want to do a better job at predicting behavior both within and across cultural groups, we need to supplement our typical reliance on explicit measures with implicit measures of motivation, beliefs, and values

Regulating Sin Across Cultures

Using text analysis, this study compares the alcohol advertising strategy in Ukraine and the United States within the context of regulatory, historical, cultural, and economic factors. Results showed that Ukrainian magazine ads contained a larger number of violations than the American ads, which complied with the letter of the law, if not the spirit. The message strategies also told different cultural stories that reflect the different ideologies for the two countries, which means that specialized advertising approaches are needed for each country. American ads situate alcohol as part of normal life, whereas Ukrainian ads demonstrate conspicuous consumption and celebrate the change to a market economy. They must not only sell the product but also teach Ukrainians how to be part of the consumer culture

Growth Hormone (GH)-Releasing Peptide Stimulation of GH Release from Human Somatotroph Adenoma Cells: Interaction with GH-Releasing Hormone, Thyrotropin- Releasing Hormone, and Octreotide.

The synthetic hexapeptide GH-releasing peptide (GHRP; His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) specifically stimulates GH secretion in humans in vivo and in animals in vitro and in vivo via a still unknown receptor and mechanism. To determine the effect of GHRP on human somatotroph cells in vitro, we stimulated cell cultures derived from 12 different human somatotroph adenomas with GHRP alone and in combination with GH-releasing hormone (GHRH), TRH, and the somatostatin analog octreotide. GH secretion of all 12 adenoma cultures could be stimulated with GHRP, whereas GHRH was active only in 6 adenoma cultures. In GHRH-responsive cell cultures, simultaneous application of GHRH and GHRP had an additive effect on GH secretion. TRH stimulated GH release in 4 of 7 adenoma cultures; in TRH-responsive cell cultures there was also an additive effect of GHRP and TRH on GH secretion. In 5 of 9 adenoma cultures investigated, octreotide inhibited basal GH secretion. In these cell cultures, GHRP-induced GH release was suppressed by octreotide. In 5 of 5 cases, the protein kinase-C inhibitor phloretin partly inhibited GHRP-stimulated GH release, but not basal GH secretion. In summary, GH secretion was stimulated by GHRP in all somatotroph adenomas investigated, indicating that its unknown receptor and signaling pathway are expressed more consistently in somatotroph adenoma cells than those for GHRH, TRH, and somatostatin. Our data give further evidence that GHRP-stimulated GH secretion is mediated by a receptor different from that for GHRH or TRH, respectively, and that protein kinase-C is involved in the signal transduction pathway. Because human somatotroph adenoma cell cultures respond differently to various neuropeptides (GHRH, TRH, somatostatin, and others), they provide a model for further investigation of the mechanism of action of GHRP-induced GH secretion

Cities and Cultures

We investigate the existence of wage premium due to cultural diversity across US cities. Using census data from 1970 to 1990, we find that at the urban level richer diversity is systematically associated with higher average nominal wages for white US-born males. We measure cultural diversity in a city using the variety of languages spoken by city-residents. While the positive correlation between wages and diversity survives a battery of robustness checks, it seems to be larger once foreign cultures have been assimilated. Finally, instrumental variable estimation hints at causation going from diversity to wages. Comparing real and nominal wages across cities, we interpret these results as evidence that diversity enhances productivity.Cultural diversity, Productivity, Wages, Metropolitan areas

Characterization of Human Pituitary Adenomas in Cell Cultures by Light And Electron Microscopic Morphology And Immunolabeling

The morphology and hormone production of pituitary adenoma cell cultures were compared in order to highlight their characteristic in vitro features. Cell suspensions were prepared from 494 surgical specimens. The 319 viable monolayer cultures were analyzed in detail by light microscopy and immunocytochemistry within two weeks of cultivation. Some cultures were further characterized by scanning, transmission and immunogold electron microscopy. The viability and detailed in vitro morphology of adenoma cells were found to be characteristic for the various types of pituitary tumors. The sparsely granulated growth hormone, the corticotroph and the acidophil stem cell adenomas provided the highest ratio of viable cultures. Occasionally, prolonged maintenance of cells resulted in long-term cultures. Furthermore, a variety of particular distributions of different hormone-containing granules were found in several cases. Both light microscopic and ultrastructural analyses proved that the primary cultures of adenoma cells retain their physiological features during in vitro cultivations. Our in vitro findings correlated with the routine histopathological examination. These results prove that monolayer cultures of pituitary adenoma cells can contribute to the correct diagnosis and are valid model systems for various oncological and neuroendocrinological studies

Connecting Dream Networks Across Cultures

Many species dream, yet there remain many open research questions in the study of dreams. The symbolism of dreams and their interpretation is present in cultures throughout history. Analysis of online data sources for dream interpretation using network science leads to understanding symbolism in dreams and their associated meaning. In this study, we introduce dream interpretation networks for English, Chinese and Arabic that represent different cultures from various parts of the world. We analyze communities in these networks, finding that symbols within a community are semantically related. The central nodes in communities give insight about cultures and symbols in dreams. The community structure of different networks highlights cultural similarities and differences. Interconnections between different networks are also identified by translating symbols from different languages into English. Structural correlations across networks point out relationships between cultures. Similarities between network communities are also investigated by analysis of sentiment in symbol interpretations. We find that interpretations within a community tend to have similar sentiment. Furthermore, we cluster communities based on their sentiment, yielding three main categories of positive, negative, and neutral dream symbols.Comment: 6 pages, 3 figure
