The globalization in business and tourism becomes crucial more and more for the economical sustainability of local communities. In the presence of an epidemic outbreak, there must be such a decision on the policy by the host community as whether to accept visitors or not, the number of acceptable visitors, or the condition for acceptable visitors. Making use of an SIRI type of mathematical model, we consider the influence of visitors on the spread of a reinfectious disease in a community, (...) especially assuming that a certain proportion of accepted visitors are immune. The reinfectivity of disease here means that the immunity gained by either vaccination or recovery is imperfect. With the mathematical results obtained by our analysis on the model for such an epidemic dynamics of resident and visitor populations, we find that the acceptance of visitors could have a significant influence on the disease’s endemicity in the community, either suppressive or supportive.

Despite its uniform appearance, the cerebellar cortex is highly heterogeneous in terms of structure, genetics and physiology. Purkinje cells (PCs), the principal and sole output neurons of the cerebellar cortex, can be categorized into multiple populations that differentially express molecular markers and display distinctive physiological features. Such features include action potential rate, but also their propensity for synaptic and intrinsic plasticity. However, the precise molecular and genetic factors that correlate with the differential physiological properties of PCs remain elusive. In this (...) article, we provide a detailed overview of the cellular mechanisms that regulate PC activity and plasticity. We further perform a pathway analysis to highlight how molecular characteristics of specific PC populations may influence their physiology and plasticity mechanisms. (shrink)

In response to the growing needs of proficient English speakers, the Taiwan Ministry of Education officially included English in standard elementary school curriculum since 2001. English courses at elementary level were extended from the fifth grade to the third grade since the fall of 2005. It is significant to examine whether the educational reform has positively affected students? learning attitudes. Through focus group interviews and questionnaire survey at six elementary schools, this study explores students? attitudes towards learning English and ways (...) of instruction. Results indicate that students generally have strong interests in English?speaking people and desire to spend time in English?speaking places. A majority of students enjoy learning English through games, and compliments from teachers or parents boost their learning motivation. The finding also reveals that English education in Taiwan seems to have directed students towards a narrow viewpoint of foreign cultures since many students associate foreigners with English?speaking people only. Finally, many students experience learning English at cram schools, which indicates the important role cram schools play in students? extracurricular learning. (shrink)

The current major models of coexistence of species on the same resources are briefly summarized. It is then shown that analysis of supposedly competitive systems in terms of the physical four dimensions of phase-space is sufficient to understand the causes for coexistence and for competitive exclusion. Thus, the multiple dimensions of niche theory are reduced to factors which define the magnitudes of the phase-spatial system, in particular the boundaries of population spaces and of periods of activity. Excluding possible cooperative interaction (...) between consumers, it appears that coexistence of species on thesame kind of limiting resource is possible only in cases of compartmentalization either in space, or in time, of resource consumption, i.e. if each consumer species disposes of a separate resource supply. Three criteria were found to be decisive for successful compartmentalization (i.e. for coexistence): 1. the vector of the resource flow; 2. relative mobility between consumers and resource units; 3. dependence or independence of resource flow on previous consumption. The traditional terminology of niche theory and of competition theory in general proved to be inadequate for analytical treatment of problems of coexistence. (shrink)

The argument is put forward that genetic mutations are viable then only, when the changed pattern of growth and/or metabolism is accommodated by the taxon-specific biochemistry of the organisms, i.e. by adaptive, somatic/physiological plasticity. The range of somatic plasticity under changing environmental conditions, therefore, has a certain predictive value for the kind of mutations that are likely to be viable.

The potential for the occurrence of multiple-role relationships is increased when professors also consult with athletic teams on their campuses. Such multiple-role relationships have potential ethical implications that are unclear and largely unexplored, and consultants may find multiple-role relationships both difficult to deal with and unavoidable. Therefore, the purpose of this study was to explore the nature of teacher-practitioner multiple-role relationships. Participants (N = 35) were recruited from Association for the Advancement of Applied Sport Psychology (AAASP) certified consultants (CCs) who (...) were also affiliated with a university (N = 68). All participants completed a 28-item survey exploring the incidence and relevant issues pertaining to multiple-role relationships. Chi-square analyses revealed that licensed mental health practitioners (i.e., psychologists and counselors) were more likely than nonlicensed AAASP CCs to believe that multiple-role relationships were never appropriate in sport psychology, 2(1, N = 30) = 12.80, p < .001, and to have never taken part in a multiple-role relationship, 2(1, N = 33) = 12.44, p < .001. Independent samples t tests revealed that mental health practitioners also reported that they would have higher levels of concern for both the practitioner, t(30) = -2.77, p = .009, and the client, t(30) = -2.50, p = .018, in such a relationship.

Nikolai Zhinkin’s review of Ernst Cassirer is so far the earliest document of the discussion in Russia about Cassirer’s conception of myth and his theory of symbolic forms. The text is published from Zhinkin’s archive. Zhinkin here notes a reorientation of Neo-Kantianism that reveals its hidden relativism and stands as a symptom of its downfall.
