Rather, ecological variables are necessary to examine structural, contextual, and sociological effects on human behavior and disease development. Schwartz, 1994 b, p. 823 Many attempts have been made to define (e.g., Rohner, 1984) and then to measure culture. Given the classic definition of culture provided by Kroeber and Kluckhohn (1952), this mapping has usually been made by using values. The most widely known value mapping is the work of Hofstede (1980), whose four value dimensions of Individualism-Collectivism, Power Distance, Uncertainty Avoidance, and Masculinity-Femininity are used as organizing and explanatory constructs in many disciplines. Tapping values salient to Chinese people, the Chinese Culture Connection (1987) has identified one additional dimension to the Hofstede four: Confucian Work Dynamism, or short-term versus long-term orientation (Hofstede, 1991). All five dimensions of culture-level values have provided the conceptual impetus for numerous cross-cultural studies. Several major cross-cultural projects have been conducted subsequent to Hofstede's (1980) groundbreaking work. With his theory-derived value survey, Schwartz (1994 a) has identified seven culture-level dimensions, namely, Conservatism, Intellectual Autonomy, Affective Autonomy, Hierarchy, Egalitarian Commitment, Mastery, and Harmony. Smith, Dugan, and Trompenaars (1996) have identified two reliable value dimensions at the cultural level from their analysis of managerial values: Egalitarian Commitment versus Conservatism, and Utilitarian Involvement versus Loyal Involvement. Smith and Bond (1998, Ch. 3) concluded that these different value surveys have produced convergent results, lending support to the validity of the cultural dimensions originally identified by Hofstede (1980). Recently, House and his associates (2003) have orchestrated a major project to identify cultural dimensions across 62 countries. A distinctive feature of this multicultural project is that values associated with leadership were measured concurrently with ideal and actual leadership behaviors. The House team has identified nine culture-level dimensions:

Based on a deductive, culturally decentered approach, new items were generated to improve the reliability of the original Social Axioms Survey, which measures individuals’ general beliefs about the world. In Study 1, results from 11 countries support the original five-factor structure and achieve higher reliability for the axiom dimensions as measured by the new scale. Moreover, moderate but meaningful associations between axiom and Big-Five personality dimensions were found. Temporal change of social axioms at the culture level was examined and found to be moderate. In Study 2, additional new items were generated for social complexity and fate control, then assessed in Hong Kong and the United States. Reliability was further improved for both dimensions. Additionally, two subfactors of fate control were identified: fate determinism and fate alterability. Fate determinism, but not fate alterability, related positively to neuroticism. Other relationships between axiom and personality dimensions were similar to those reported in Study 1. The short forms of the axiom dimensions were generally reliable and correlated highly with the long forms. This research thus provides a stronger foundation for applying the construct of social axioms around the world.

Educators in medical schools around the world are presently experimenting with innovative ways of using web-based learning to supplement the existing teaching and learning process. We have recently used a popular open-source course management system (CMS) called the modular object-oriented dynamic learning environment (Moodle) to construct an online site (DPhysiol) to facilitate our face-to-face teaching of physiology to a group of first-year students in the Bachelor of Medicine and Bachelor of Surgery program. The integration of the Moodle site into our teaching was assessed using online log activity, student examination marks, and feedback from students. The freely available Moodle platform was simple to use, helped to effectively deliver course materials, and has features that allowed cooperative learning. Students who used the CMS throughout their academic year and commented favorably regarding its use as a complement to the face-to-face classroom sessions. The group of students used the CMS obtained significantly higher scores in the final examination compared with the previous class that did not use the CMS. In addition, there was a significant correlation between student participation and performance in online quizzes and their final examination marks. However, students' overall online usage of the CMS did not correlate with their examination marks. We recommend Moodle as a useful tool for physiology educators who are interested in integrating web-based learning into their existing teaching curriculum.

Purpose:To study the effects of varying lipid concentrations, lipid and oil ratio, and the addition of propylene glycol and lecithin on the long-term physical stability of nanostructured lipid nanocarriers (NLC), skin hydration, and transepidermal water loss. Methods: The various NLC formulations (A1-A5) were prepared and their particle size, zeta potential, viscosity, and stability were analyzed. The formulations were applied on the forearms of the 20 female volunteers (one forearm of each volunteer was left untreated as a control). The subjects stayed for 30 minutes in a conditioned room with their forearms uncovered to let the skin adapt to the temperature (22°C ± 2°C) and humidity (50% ± 2%) of the room. Skin hydration and skin occlusion were recorded at day one (before treatment) and day seven (after treatment). Three measurements for skin hydration and skin occlusion were performed in each testing area. Results: NLC formulations with the highest lipid concentration, highest solid lipid concentration, and additional propylene glycol (formulations A1, A2, and A5) showed higher physical stability than other formulations. The addition of propylene glycol into an NLC system helped to reduce the particle size of the NLC and enhanced its long-term physical stability. All the NLC formulations were found to significantly increase skin hydration compared to the untreated controls within 7 days. All NLC formulations exhibited occlusive properties as they reduced the transepidermal water loss within 7 days. This effect was more pronounced with the addition of propylene glycol or lecithin into an NLC formulation, whereby at least 60% reduction in transepidermal water loss was observed. Conclusion: NLCs with high lipid content, solid lipid content, phospholipid, and lecithin are a highly effective cosmetic delivery system for cosmetic topical applications that are designed to boost skin hydration.
