Code-Switching and Competition: An Examination of a Situational Response

Code switching is primarily a linguistic term that refers to the use of two or more languages within the same conversation, or same sentence, to convey a single message. One field of linguistics, sociocultural linguistics, is broad and interdisciplinary, a mixture of language, culture, and society. In sociocultural linguistics, the code, or language that is selected, can be triggered by a social situation or setting in which the speaker is placed. Code-switching can also apply to behavior. In physical education, teachers may communicate in the language of sport. When teaching a competitive activity in physical education class, the environment changes, becomes competitive, and the teachers often code switch and switch instructional choices unconsciously. This article examines the occurrence of code-switching during competitive activities.     

Graduateness: an empirical examination of the formative function of university education

The formative merits of university education are at risk of being reduced from graduateness in the sense of broad academic cultivation to professional training with a strong emphasis on employability. The difficulty in opposing this trend is the absence of a clear framework for academic cultivation. The aim of this study is to construct a model that uses the formative function of university education as a starting point, that distinguishes graduateness from employability, and that integrates theories on reflective thinking, scholarship, moral reasoning and lifelong learning. This approach offers the possibility of making use of insights from established theoretical traditions in the study of the intellectual development of students. For this study, a questionnaire was developed to investigate graduateness, or intellectual cultivation, among students in a research university. Structural equation modelling revealed that the expected structure was confirmed by the data. Reflective thinking has the strongest influence on lifelong learning; however, scholarship and moral citizenship are also important elements.     

Interference and auditory short-term memory in the bottlenosed dolphin

Interference in auditory short-term memory in the bottlenosed dolphin,Tursiops truncatus (Montagu), was studied using a delayed matching-to-sample task. At each trial, one of two sample sounds, chosen randomly, was projected underwater for 4 sec and then, after a variable delay interval, both sounds were presented. A response to the sound matching the initial sample was reinforced. Correct matching was significantly reduced following short intervals between trials in combination with long delays after the sample (proactive interference), or when a near continuous irrelevant sound was inserted into the delay interval (retroactive interference). There was rapid habituation to interference if the irrelevant sound was short in duration relative to the delay interval. For both proactive and retroactive interference, the errors were predominantly responses to the sample sound appropriate to the prior trial rather than to the current trial, indicating that memory for the relative recency of events (temporal memory) was degraded by interference. When interference was deleted or minimized, temporal memory remained nearly perfect over 30-sec delay intervals, the longest tested. The importance of distinguishing between temporal memory and nontemporal, or event, memory in different forms of the delayed matching task was emphasized.     

Screening for lead poisoning in urban school children of southern India using capillary and venous blood samples

Our study aimed at comparing lead and zinc protoporphyrin (ZPP) levels in capillary and venous blood samples in a small population and to employ an easier method of sample collection for a major screening program in school children in major Indian cities. An awareness program on lead and its effects was conducted in two different schools. A total of thirty urban school children from South India, with an age group between 4–12 years consented for dual blood sampling and reported for the study. Venous and capillary blood samples were obtained simultaneously. Blood lead and zinc protoporphyrin (ZPP) levels were estimated using ESA Lead Analyzer and Haematofluorometer respectively. A significant correlation between capillary and venous ZPP (r=0.98) and lead (r=0.99) was observed. Rank sum test showed that there is no statistically significant difference between capillary and venous ZPP (P=0.891) and lead (P=0.672) values. This pilot study recommends that screening for lead may be done using capillary blood samples since significant correlation is observed between capillary and venous blood measurements. Obtaining samples using this mode is a non-invasive, less expensive, quick and easy method in children. Appropriately performed capillary sampling may be considered as an acceptable alternative to venipuncture for screening of blood for lead poisoning both in children and adults.     

Gender organization of schooling and television viewing among early adolescents: a test of two alternative hypotheses

In this analysis, single‐sex and mixed schools are compared in terms of pupils' television viewing habits, the latter factor being considered as an indicator of a pupil's sense of educational responsibilities. It was hypothesized that the presumably lower levels of television watching among girls attending single‐sex schools could be explained by school climate factors pertaining to adolescent subculture values and/or to the pedagogic approaches of a predominantly female staff. Use was made of data from 68 academic‐type secondary schools in Flanders (Belgium). Of these schools, 25 were mixed and 43 were single‐sex (21 girls', and 22 boys' schools). Respondents were third‐year pupils: 3370 girls and 3057 boys, aged 14 and 15 years. A multilevel analysis (HLM) was performed controlling for parental socio‐economic status, curriculum enrolment, school residency and school mean SES. The results mainly indicate that the differential effect of single‐sex and coeducational schools on girls' TV watching habits may be partially accounted for by factors associated with pedagogic approaches by the predominantly female staff in girls' schools, but not at all by norms related to the adolescent subculture.     

Faculty Incentives for Online Course Design, Delivery, and Professional Development

This quantitative study investigated the types and frequency of incentives for online instruction at non-profit institutions of higher education with an established teaching and learning development unit. While up to 70 % of institutions offer incentives, this support is not universal and varies by incentive type and purpose.
