An Ecological Perspective of Latina/o College Student Ethnicity

Although Latinos are the largest minority population in the United States and the largest minority population on American campuses, there is little research concerning Latino college student ethnic identity. This study incorporates an ecological model to examine the levels of influence of different settings and backgrounds of Latino college students. The findings show that Latinos from different countries of origin and within the same countries of origin identify their ethnic identity differently depending on several factors including generation, immigration status, country of origin, language preferences, and discrimination.     

Absorption of creatine supplied as a drink, in meat or in solid form.

We examined the plasma concentration curve obtained over 6 h after the ingestion of 2 g of creatine (Cr) (equivalent to 2.3 g Cr x H2O) contained in meat or in solution in five non-users of creatine supplements. Peak plasma creatine concentration was lower after the ingestion of meat but was maintained close to this for a longer period. Measurements of the area under the plasma concentration curve indicated approximate bioequivalence of creatine contained in meat with the same dose supplied in a solution. In a separate study, we examined the plasma concentration time curve after ingestion of solid Cr x H2O. Creatine ingested as a lozenge (crushed in the mouth and swallowed) or as a crystalline suspension in ice cold water resulted in a 20% lower peak concentration and 30-35% smaller area under the plasma creatine concentration curve than the same dose administered in solution. Despite a possibly lower bioavailability, 2.3 g Cr x H2O supplied in either solid form was nonetheless sufficient to raise the plasma concentration five- to six-fold in individuals with a mean body mass of 75.6 kg. We conclude that creatine administered as meat or in solid form is readily absorbed but may result in slightly lower peak concentrations than when the same dose is ingested as a solution.     

Longitudinal monitoring of power output and heart rate profiles in elite cyclists

Abstract

Power output and heart rate were monitored for 11 months in one female ([Vdot]O_2max: 71.5 mL · kg^?1 · min^?1) and ten male ([Vdot]O_2max: 66.5 ± 7.1 mL · kg^?1 · min^?1) cyclists using SRM power-meters to quantify power output and heart rate distributions in an attempt to assess exercise intensity and to relate training variables to performance. In total, 1802 data sets were divided into workout categories according to training goals, and power output and heart rate intensity zones were calculated. The ratio of mean power output to respiratory compensation point power output was calculated as an intensity factor for each training session and for each interval during the training sessions. Variability of power output was calculated as a coefficient of variation. There was no difference in the distribution of power output and heart rate for the total season (P = 0.15). Significant differences were observed during high-intensity workouts (P < 0.001). Performance improvements across the season were related to low-cadence strength workouts (P < 0.05). The intensity factor for intervals was related to performance (P < 0.01). The variability in power output was inversely associated with performance (P < 0.01). Better performance by cyclists was characterized by lower variability in power output and higher exercise intensities during intervals.     

How linguistically‐informed are phonics programmes?

Successive UK government policies have strengthened the phonics element of the National Curriculum for English in England. The policies have included inviting publishers to submit completed self‐assessments of their systematic phonics programmes. The self‐assessment criteria focus on what is deemed to be ‘high‐quality provision’, as defined in the Independent Review of the Teaching of Early Reading chaired by Jim Rose. The programmes whose self‐assessments were judged to be accurate by small panels of independent evaluators have been subsequently listed on a central government website. The authors have acted as independent evaluators in this process and, between them, had the opportunity to inspect the content of over 100 phonics programmes. They have noted that many of these programmes (most of which did not meet the Rose criteria) contained numerous linguistic inaccuracies, particularly in relation to the English spelling system and its grapheme‐phoneme correspondences. The existence, number and range of these errors jeopardise policy implementation and National Curriculum delivery and pose risks for the quality of teaching and learning. The article suggests some reasons for these findings in related published debates and in policy documents, and that phonics programmes need to be more linguistically‐informed. The article concludes with some implications for practice.     

Effects of novelty-reducing preparation on exploratory behavior and cognitive learning in a science museum setting

The purpose of this study was to examine the relationships between (a) novelty and exploratory behavior, (b) novelty and cognitive learning, and (c) exploratory behavior and cognitive learning in science museums. Sixty-four sixth-grade public school students participated in a posttest-only control group design. The control group received a treatment designed to decrease the novelty of a field trip setting through a vicarious exposure while the placebo group received an informative but not novelty-reducing treatment. Both groups then visited the field site where they were videotaped. Statistical analyses were conducted on both dependent variables with socioeconomic status and academic achievement as covariates, novelty-reducing preparation as the independent variable, and gender as moderator variable. Exploratory behavior was shown to be positively correlated with cognitive learning. Significant differences were detected for exploratory behavior. For both dependent variables, gender by treatment group interaction was significant with novelty-reducing preparation shown to be highly effective on boys but having no effect on girls.     

Learning pathways between and within vocational and higher education: towards a typology?

Promotion by governments of the provision of pathways for learners and the principle of seamlessness in post-compulsory education over the past decade may be perceived as both positive and problematic. Seamlessness can provide considerable choice and yet can readily lead to uncertainty and indecision. A number of studies have drawn attention to the phenomenon of indirect transfer, where the movement of tertiary students is not linear but involves several moves within and between sectors. This paper explores patterns in such movements and proposes a typology of five learning pathways. The research involved in-depth interviews held with 69 students in South Australia who had experienced both vocational and higher education sectors. Such research can help educators and researchers understand more fully the experiences in and reasons for moving within and between various pathways. It can also assist policymakers and institutional planners with insights into how best to fashion relationships between sectors and tailor policies and services that help learners navigate through education systems.
