IF GEOGRAPHY IS HISTORY,WHAT HAPPENS TO COMMUNITY COLLEGES?

With the approach of ubiquitous access to distributed learning resources, the old regional basis for community colleges is rapidly evaporating. In order to survive as vibrant and relevant institutions, we will be challenged to re-think the nature and purpose of our institutions and to develop new services for our students and the communities we serve. These new services will augment and extend our traditional roles and will be firmly based on the enduring values of the community college movement. But distributed learning programs and courses are expensive to develop. If colleges are to fully deliver on distributed learning's promise of increased access and flexibility, then we will need to learn to both compete and collaborate at the same time.

Accuracy of pacing during breaststroke swimming using a novel pacing device,the Aquapacer™

Generally, swimmers pace themselves using their own judgement and the poolside clock during swimming training, fitness testing protocols or scientific investigation. The Aquapacer? is a new pacing device that can be used to pace the swimming speed or stroke rate of the swimmer. The aims of this study were to determine if breaststroke swimmers could pace accurately during submaximal swimming using a poolside clock (Study 1) and the Aquapacer? (Study 2), at swimming speeds at, just above and just below maximal 200 m time-trial speeds (using the Aquapacer?, Study 3) and under three different race pacing conditions (using the Aquapacer?, Study 4). Between 8 and 15 male national or club standard 200 m breaststroke swimmers participated in each of the studies. The swimmers in Study 2, despite being less well trained than the swimmers in Study 1 and part of a more heterogeneous group in terms of swimming performance, repeatedly demonstrated less random error in pacing, suggesting that the Aquapacer? may be preferable to the poolside clock when swimmers are being required to pace accurately. The Aquapacer? also enabled swimmers to pace accurately at racespecific swimming speeds (until fatigue precluded them from holding pace) (Study 3), and through a change in pace at race-specific speeds (Study 4), which suggests that it may be of use in entraining racing strategies.     

Chronic weight control impacts on physiological function and bone health in elite jockeys

Abstract

The aim of this study was to evaluate the impact of weight restrictions on physiological function and bone health in a group of horse racing jockeys. Twenty-seven elite male jockeys participated in this study (17 flat jockeys; 10 national hunt jockeys). Participants completed a range of measurements including anthropometry, hydration analysis, bone mineral density assessment, and musculoskeletal screening. Fifty-nine percent of flat and 40% of national hunt jockeys showed osteopenia in one or more of the total body, hip or spine scans. Mean urine-specific gravity (Usg) values revealed moderate dehydration on a non-race day (Usg = 1.022 ± 0.005 and 1.021 ± 0.007 for flat and national hunt jockeys respectively). Analysis of a number of flat jockeys (n = 11) revealed marked dehydration on an official race day (Usg = 1.028 ± 0.005). Sixty-four percent of participants reported a current injury at the time of assessment. Our results reveal some worrying trends within this population. Further research is required to examine the effects of current weight control practices typically used by jockeys on both physiological and cognitive function as well as health and performance.     

Measurement procedures affect the interpretation of metatarsophalangeal joint function during accelerated sprinting

Abstract

The metatarsophalangeal joint (MPJ) is a significant absorber of energy in sprinting. This study examined the influence of MPJ axis choice and filter cut-off frequency on kinetic variables describing MPJ function during accelerated sprinting. Eight trained sprinters performed maximal sprints along a runway. Three-dimensional high-speed (1000 Hz) kinematic and kinetic data were collected at the 20 m point. Three axis definitions for the five MPJs were compared. MPJ moments, powers and energies were calculated using different filter cut-off frequencies. The more anatomically appropriate dual axis resulted in less energy absorbed at the MPJ compared to the oblique axis which also absorbed less energy compared to the perpendicular axis. Furthermore, a low cut-off frequency (8 Hz) substantially underestimated MPJ kinematics, kinetics and the energy absorbed at the joint and lowered the estimate of energy production during push-off. It is concluded that a better understanding of MPJ function during sprinting would be obtained by using an oblique or anatomically appropriate representation of the joint together with appropriate kinematic data sampling and filtering so that high frequency movement characteristics are retained.

Testing Injustice: Examining the Consequential Validity of edTPA

In this case study, we examine the consequential validity of using edTPA in a social justice-oriented, urban teacher preparation program. According to the developers of edTPA, a primary purpose is to support teacher candidate learning, yet our analysis suggests that edTPA does not support learning when used during student teaching. Our 16 participants, who are primarily teacher candidates of color and many first-generation college students, and who all passed edTPA, unanimously indicated that edTPA increased their mental and financial stress, which they linked to design elements including high stakes, standardization, and external scoring. Participants also critiqued the construct of teaching represented in edTPA, arguing that dispositions and a social justice orientation are missing and that edTPA is more about following procedures than supporting candidate learning. Moreover, edTPA encouraged inequitable practices, including focusing on high-achieving classes and selecting curricula based on scoring procedures instead of student need. Overall, our analysis indicates that there is not strong consequential validity evidence to support the use of edTPA as an assessment during student teaching, particularly in social justice-oriented programs, yet suggests edTPA could be a useful tool if stakes and proceduralism are reduced and scoring is conducted locally.     

Cognate Awareness in French Immersion Students: Contributions to Grade 2 Reading Comprehension

Cognate awareness is the ability to recognize the cognate relationship between words in two etymologically related languages. The current study examined the development of cognate awareness and its contribution to French (second language) reading comprehension among Canadian French immersion children. Eighty-one students were tested at the end of Grade 1 and again at the end of Grade 2. Children were administered a cognate awareness task in French, in which they were asked to decide whether a French word had a cognate in English. Overall, performance on the cognate awareness task was significantly above chance at both time points, and it improved overtime. Thus, for the majority of the participants, cognate awareness was evident as early as first grade. Regressions revealed that cognate awareness measured in Grades 1 and 2 made a significant contribution to Grade 2 French reading comprehension, beyond multiple controls. The results of the study suggest that cognate awareness is a unique aspect of second-language reading comprehension in young bilingual children.     

The Development of Adolescents' Emotional Stability and General Self-Concept: The interplay of parents,peers, and gender

Gender differences associated with the development of adolescents' sense of general self-concept (confidence and self-worth) and emotional stability (calmness, freedom from anxiety, and depression) were investigated using a sample of 655 adolescents (mean age 16 years). Relationships with parents were important for males' emotional stability but not females' and so this finding challenges the belief that adolescent males are more concerned with establishing independence from parents than females. The research also challenges the notion that adolescent boys are less interested in close personal peer relationships than girls. Same sex and opposite sex peer relationships were more influential in the formation of adolescents' emotional stability than parental relationships. A reciprocal relationship was revealed between general self-concept and emotional stability. Comparing these results with results obtained on the same students 18 months previously (aged 14.5 years), demonstrates that adolescents increasingly transfer their emotional attachment from parents to peers in a process called individuation.     

Non-national museum attendances in the UK. Part 2: counting them in

ABSTRACT

This is the second of two papers that together present an interim report on a study of visit numbers to UK regional and local museums. It identifies trends in museum visiting between 1891 and 2015 within the context of socio-economic change, and discusses the principle causes of annual variances (sometimes of substantial magnitude) at a local level. It suggests that changes in visit levels are generally within the control of a museum rather than the consequence of external influences, and questions how far the experience of the period since 2001 is comparable with what has gone before.
