In the Name of Diversity: Education and the Commoditization and Consumption of Race in the United States

In exploring the relationship between cultural capital, symbolic violence and the diversification of the curriculum the notion of commoditization of race in higher education is developed. The term first and foremost emphasizes how students from “disadvantaged” racialized communities remain significantly under-represented at selective universities and colleges. Commoditization of race in higher education is also concerned with the potentially unequal terms of exchange between racialized communities, whose experiences and collective struggles are increasingly embodied in novels, poetry, non-fictional works, ethnographies, academic discourses, and programs of study, and the educational benefits associated with diversity at 4-year institutions accorded predominantly to white student bodies. In doing so, the paper demonstrates that race-based segregation initiated at the neighborhood and public school levels continues to inhibit racialized students from receiving quality higher education opportunities. Based on an analysis of the economic obstacles disproportionately affecting Black communities, the paper concludes by reiterating that unless selective universities and colleges are prepared to significantly enhance quality educational opportunities for students of color, even the most sincere expressions of support for affirmative action, multiculturalism and diversity will likely legitimate, rather than challenge, racial inequality in the foreseeable future.

Effects of low volume isometric leg press complex training at two knee angles on force-angle relationship and rate of force development

This study compared knee angle-specific neuromuscular adaptations after two low-volume isometric leg press complex training programmes performed at different muscle lengths. Fifteen young males were divided into two groups and trained three times per week for 6 weeks. One group (n?=?8) performed 5–7 sets of 3 s maximum isometric leg press exercise, with 4?min recovery, with knee angle at 85°?±?2° (longer muscle-tendon unit length; L-MTU). The other group (n?=?7) performed the same isometric training at a knee angle of 145°?±?2° (180°^?=?full extension; shorter muscle-tendon unit length; S-MTU). During the recovery after each set of isometric exercise, participants performed two CMJ every minute, as a form of complex training. Maximum isometric force (MIF) and rate of force development (RFD) were measured over a wide range of knee angles. Countermovement jump (CMJ) performance and maximum half-squat strength (1RM) were also assessed. Training at S-MTU induced a large increase of MIF (22–58%, p?p?p?=?0.001). In contrast, training at L-MTU, resulted in a moderate and similar (≈12.3%, p?=?0.028) improvement of force at all knee angles. CMJ performance and 1RM were equally increased in both groups after training by 10.4%?±?8.3% and 7.8%?±?4.7% (p?相似文献   

Facilitation of licking by response-contingent electric shock

Licking behavior of rats maintained by lick-contingent water reinforcement, produced electric shocks under three conditions. Shock occurred 1 sec before, simultaneous with, or 1 sec after water reinforcement. Rates of licking rose above prepunished levels at .2-, .4-, and .6-mA intensities but were suppressed at .8 mA for all three groups. Facilitation and suppression effects were the same for the three pairing conditions. Discriminative and elicited functions of shock did not appear to account for this facilitative effect.     

Promoting general metacognitive awareness

I describe two aspects of metacognition, knowledge of cognition and regulation of cognition, and how they are related to domain-specific knowledge and cognitive abilities. I argue that metacognitive knowledge is multidimensional, domain-general in nature, and teachable. Four instructional strategies are described for promoting the construction and acquisition of metacognitive awareness. These include promoting general awareness, improving self-knowledge and regulatory skills, and promoting learning environments that are conducive to the construction and use of metacognition.     

Measurement Error, Multidimensionality, and Scale Shrinkage: A Reply to Yen and Burket

Yen and Burket (1997) provided a critical analysis of the work by Camilli (1988) regarding scale shrinkage, and suggested that shrinkage in vertical equating cannot be understood apart front multidimensionality. In this response, select research on reliability, multidimensionality and scale shrinkage are reviewed. These perspectives are then integrated with issues of practical importance to educators.     

Relation of psycholinguistic development to imaginative play of disadvantaged preschool children

The relation of imaginative play to psycholinguistic development was investigated in a sample of disadvantaged preschool children. The children were assigned to high and low play groups based on their level of play organization. The high play group was significantly more mature in overall psycholinguistic development than the low play group. Further analyses revealed that while the groups did not vary in Auditory Reception, the high play group earned more advanced scores on the Auditory-Vocal Association and Verbal Expression tasks that did the low play group. Moreover, the high play group engaged in more task-relevant speech during play than did the low play group, although the groups did not differ in amount of task-irrelevant speech. The role of psycholinguistic, cognitive, and environmental factors in the development and organization of imaginative play was discussed.     

The relative contribution of training intensity and duration to daily measures of training load in professional rugby league and union

ABSTRACT

This study examined the relative contribution of exercise duration and intensity to team-sport athlete’s training load. Male, professional rugby league (n = 10) and union (n = 22) players were monitored over 6- and 52-week training periods, respectively. Whole-session (load) and per-minute (intensity) metrics were monitored (league: session rating of perceived exertion training load [sRPE-TL], individualised training impulse, total distance, BodyLoad?; union: sRPE-TL, total distance, high-speed running distance, PlayerLoad?). Separate principal component analyses were conducted on the load and intensity measures to consolidate raw data into principal components (PC, k = 4). The first load PC captured 70% and 74% of the total variance in the rugby league and rugby union datasets, respectively. Multiple linear regression subsequently revealed that session duration explained 73% and 57% of the variance in first load PC, respectively, while the four intensity PCs explained an additional 24% and 34%, respectively. Across two professional rugby training programmes, the majority of the variability in training load measures was explained by session duration (~60–70%), while a smaller proportion was explained by session intensity (~30%). When modelling the training load, training intensity and duration should be disaggregated to better account for their between-session variability.
