The Politics of Illegal Immigration,Bilingual Education,and the Commodity of the Post-Technological Society

With the increasing number of undocumented workers entering the United States and the costs associated with educating their children, bilingual education may soon become the target of opponents of illegal immigration. Furthermore, recent leftist shifts in Latin American governments have provided an impetus for an educated biliterate population that can build bridges with these countries. This will promote safety for all who live within the Americas, protecting them from acts of aggression and terrorism while promoting commerce and shared progress.     

The effect of an intervention to improve newly qualified teachers’ interpersonal style,students motivation and psychological need satisfaction in sport-based physical education

Recent developments in self-determination theory research in the educational setting (e.g., Reeve, Deci, & Ryan, 2004), suggest that teachers’ interpersonal style should be considered as consisting of three dimensions: autonomy support, structure and interpersonal involvement. Based on this theoretical proposition, the purpose of the present study was to test the effects of a training program for three physical education newly qualified teachers on the aforementioned teachers’ overt behaviors and students’ psychological needs satisfaction, self-determined motivation and engagement in sport-based physical education. After a baseline period of four lessons, the teachers attended an informational session on adaptive student motivation and how to support it. The training program also included individualized guidance during the last four lessons of the cycle. Results revealed that from pre- to post-intervention: (1) teachers managed to improve their teaching style in terms of all three dimensions, and (2) students were receptive to these changes, as shown by increases in their reported need satisfaction, self-determined motivation and engagement in the class.     

Elongated unique DNA strand deposition on microstructured substrate by receding meniscus assembly and capillary force

Ordered deposition of elongated DNA molecules was achieved by the forced dewetting of a DNA solution droplet over a microstructured substrate. This technique allows trapping, uncoiling, and deposition of DNA fragments without the need of a physicochemical anchoring of the molecule and results in the combing of double stranded DNA from the edge of microwells on a polydimethylsiloxane (PDMS) substrate. The technique involves scanning a droplet of DNA solution caught between a movable blade and a PDMS substrate containing an array of microwells. The deposition and elongation appears when the receding meniscus dewets microwells, the latter acting here as a perturbation in the dewetting line forcing the water film to break locally. Thus, DNA molecules can be deposited in an ordered manner and elongated conformation based solely on a physical phenomenon, allowing uncoiled DNA molecules to be observed in all their length. However, the exact mechanism that governs the deposition of DNA strands is not well understood. This paper is an analysis of the physical phenomenon occurring in the deposition process and is based on observations made with the use of high frame/second rate video microscopy.     

Research and Learning Information Resources

Founded in 1970 , with a mission of accessibility , flexibility , and affordability , the Community College of Vermont ( CCV ) has a unique decentralized organization . CCV serves more than 7 , 000 students - primarily adults studying part - time annually through a network of 12 learning centers across the state , without owning any real estate and without any full - time faculty . After becoming Vermont's second largest college in the 1980's , CCV inaugurated a "virtual campus," an integrated voice / data wide - area network , which has fostered communication and creativity in both the academic and administrative arenas . One of Vermont's five state colleges , CCV offers credit courses , non - credit workshops , certificates and associate degree programs in a wide range of subjects . As an open - admissions institution , CCV supports its students through computerized skills assessments , developmental courses and workshops , and a very successful skill - building course Dimensions of Learning. In recent years , the college has developed strong partnerships with state agencies and businesses to help foster lifelong learning for Vermont's workforce and has forged transfer agreements with many four - year colleges .     

The sensorium and fleshy schools

As places of learning, schools inevitably foreground cognition. Neglected in schools and in the literature is the body, often an inconvenience or barrier to learning rather than a site of perception and understanding. Where the body is considered, it is primarily concerned with pedagogy and children rather than analysing the broad range of embodied experience: teachers' sensuous experience is side-lined; classrooms are central, with toilets and staffrooms and corridors usually ignored; policy and architecture largely unconsidered. Furthermore, ironically, the focus in the literature also foregrounds the body within its contribution to cognition rather than centring the fleshy experience of sensing. This paper therefore addresses these omissions and focuses on the sensorium—movement, the haptic, hearing, smell/taste and visual—providing a framework to analyse the truly embodied experience of the school environment. It argues that as well as being culturally bound, the sensorium is delineated and encoded within the educational ideology and architecture of schools, prescribed by senior leaders to manage and police the flesh within their school walls.     

Repeated high-intensity exercise in professional rugby union

Abstract

The aim of the present study was to describe the frequency, duration, and nature of repeated high-intensity exercise in Super 14 rugby union. Time–motion analysis was used during seven competition matches over the 2008 and 2009 Super 14 seasons; five players from each of four positional groups (front row forwards, back row forwards, inside backs, and outside backs) were assessed (20 players in total). A repeated high-intensity exercise bout was considered to involve three or more sprints, and/or tackles and/or scrum/ruck/maul activities within 21 s during the same passage of play. The range of repeated high-intensity exercise bouts for each group in a match was as follows: 11–18 for front row forwards, 11–21 for back row forwards, 13–18 for inside backs, and 2–11 for outside backs. The durations of the most intense repeated high-intensity exercise bouts for each position ranged from 53 s to 165 s and the minimum recovery periods between repeated high-intensity exercise bouts ranged from 25 s for the back row forwards to 64 s for the front row forwards. The present results show that repeated high-intensity exercise bouts vary in duration and activities relative to position but all players in a game will average at least 10 changes in activity in the most demanding bouts and complete at least one tackle and two sprints. The most intense periods of activity are likely to last as long as 120 s and as little as 25 s recovery may separate consecutive repeated high-intensity exercise bouts. The present findings can be used by coaches to prepare their players for the most demanding passages of play likely to be experienced in elite rugby union.     

Shyness and Trajectories of Functional Network Connectivity Over Early Adolescence

High shyness during early adolescence is associated with impaired peer relationships and risk for psychiatric disorders. Little is known, however, about the relation between shyness and trajectories of brain development over early adolescence. The current study longitudinally examined trajectories of resting‐state functional connectivity (rs‐fc) within four brain networks in 147 adolescents. Subjects underwent functional magnetic resonance imaging at three different time points, at average ages 10.5 (range = 7.8–13.0), 11.7 (range = 9.3–14.1), and 12.9 years (range = 10.1–15.2). Multilevel linear modeling indicated that high shyness was associated with a less steep negative slope of default mode network (DMN) rs‐fc over early adolescence relative to low shyness. Less steep decreases in DMN rs‐fc may relate to increased self‐focus in adolescents with high shyness.     

An analysis of the validity of the three-mile run as a field test of aerobic capacity in college males

The purpose of the present investigation was to examine the concurrent and construct validity of the three-mile (4.83 km) run as a field test of aerobic capacity. Subjects included 109 college-aged males whose three-mile run time (M = 1310.31 +/- 184.48 s) was measured. Fifty of the subjects were given a maximal treadmill stress test, and their peak oxygen consumption (VO2peak) (M = 54.23 +/- 7.08 ml.kg-1.min-1) was measured. The three-mile run was conducted on an outdoor 0.25 mile (0.425 km) track, and split times were recorded each 110 yds (100.32 m) for the first and last laps and total time was recorded for laps 2 through 11. The correlation coefficient between the run time and VO2peak was -.58, indicating only moderate concurrent validity for the run as a field test for aerobic capacity. A factor analysis conducted on the split time data revealed a three-factor structure of a stable pace phase, an initial sprint, and a final sprint with the stable pace factor accounting for most of the common factor variance (69%). The three-mile run time was used to discriminate successfully between two known groups of subjects in aerobic capacity. These data provide a degree of support for the construct validity of the three-mile run as a field test of aerobic capacity.
