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. 相似文献

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. 相似文献

This study was conducted to find out the level of oxidative stress and effect of supplementation of vitamin C, D and Calcium
on levels of SOD, serum and urinary fluoride in children residing in endemic fluorosis area. For this the fluoride belt of
Jaipur district was selected. The parameters selected were Super oxide dismutase, serum fluoride and urinary fluoride. The
study was conducted on one hundred children, selected from four areas (25 from each area) consuming water containing 1.2,
2.4, 5.6 and 13.6 mg/l of fluoride. Drinking water fluoride, serum and urinary fluoride were measured by Ion selective electrode
method. Serum SOD by Xanthine oxidase method using kit of Ransod (kit cat. No. SD125). The post treatment values showed a
significant reduction in serum fluoride and SOD. Urinary fluoride levels increased significantly in post treatment stage.
The results revealed a normal SOD levels in all groups but an increasing trend was observed with increasing fluoride concentration.
Treatment with Calcium, Vitamin D and Vitamin C showed a significant reduction in serum fluoride and SOD and increase in urinary
fluoride. A high positive correlation between pretreatment and post treatment group was observed in serum fluoride, SOD and
urinary fluoride (P < 0.05). The study indicated an increasing oxidative stress in cases of fluorosis with increasing drinking
water fluoride concentration. Treatment with Calcium, Vitamin D and Vitamin C resulted a significant reduction in serum fluoride
and SOD and increase in urinary fluoride. 相似文献

Folate and cobalamin (Vitamin B12) are two essential micronutrients involved in one-carbon metabolism, which affects heart disease, neural tube defects and
cancer. Methylenetetrahydrofolate reductase, the key enzyme involved in one carbon metabolism produces methyl tetrahydrofolate
from methylene tetrahydrofolate, which in turn donates methyl group to homocysteine to generate methionine. There exist two
common low function polymorphic variants of the methylenetetrahydrofolate reductase gene involving nucleotides 677 C→T and
1298 A→C, which are associated with hyperhomocysteinemia. These polymorphisms are also linked with increased risk for certain
cancers such as breast cancer and at the same time providing a protective effect on colorectal cancer. In this case control
study, we have evaluated levels of folic acid, vitamin B12 and homocysteine in patients with colorectal cancer. Folate and homocysteine levels did not differ significantly between
the two groups; however an increasing trend was noticed with increase in homocysteine levels. Vitamin B12 levels were increased in cases compared to control group. 相似文献

This review presents a conceptual framework and supporting evidence that links impaired motor control after sport-related concussion(SRC)to increased risk for musculoskeletal injury.Multiple studies have found that athletes who are post-SRC have higher risk for musculoskeletal injury compared to their counterparts.A small body of research suggests that impairments in motor control are associated with musculoskeletal injury risk.Motor control involves the perception and processing of sensory information and subsequent coordination of motor output within the central nervous system to perform a motor task.Motor control is inclusive of motor planning and motor learning.If sensory information is not accurately perceived or there is interference with sensory information processing and cognition,motor function will be altered,and an athlete may become vulnerable to injury during sport participation.Athletes with SRC show neuroanatomic and neurophysiological changes relevant to motor control even after meeting return to sport criteria,including a normal neurological examination,resolution of symptoms,and return to baseline function on traditional concussion testing.In conjunction,altered motor function is demonstrated after SRC in muscle activation and force production,movement patterns,balance/postural stability,and motor task performance,especially performance of a motor task paired with a cognitive task(i.e.,dual-task condition).The clinical implications of this conceptual framework include a need to intentionally address motor control impairments after SRC to mitigate musculoskeletal injury risk and to monitor motor control as the athlete progresses through the return to sport continuum. 相似文献

Key points
- Early career researchers (ECRs) consider journals the central form of communication – but are concerned about pressure to publish.
- ECRs want to share but currently accept the closed publishing system because of the need to build a traditional reputation.
- ECRs know – and appear to care – little about publishers but trust them as publishing and reviewing facilitators.
- Editors are criticized for not managing peer review with better selection of reviewers.
- Megajournals are not seen as the future journal form and criticized for lack of selectivity.
- ECRs want open access/science in principle but are circumspect about their contribution to it.
- ResearchGate is a key force for change as ECRs consider it a mainstay communication and reputation platform.

A bstract . In this essay, Chaya Herman explores the interaction between two powerful global dynamics that have affected educational institutions and society at large: one is neoliberalism, with its attendant notions of marketization and managerialism; the other is the resurgence of ethnic and religious, often fundamentalist, communities in the search for identity. The essay is based on a larger research project that explores the profound effects of the ideological and managerial restructuring process in Johannesburg's Jewish community schools, the broader context for which has been South Africa's transformation to democracy. Herman suggests that these two dynamics are synergetic forces and that their accumulated effect has the power to shift the discourse of the community toward ghettoization and toward the creation of a homogenous community founded on a narrowly defined common identity. 相似文献
