How times change: Secondary teachers' job satisfaction and dissatisfaction in 1962 and 2007

In this article we explore the level of job satisfaction and the sources of job dissatisfaction for 210 secondary school teachers in southwest England and compare our results with the results from a similar study published in 1962. Using anonymous questionnaires, we asked 210 secondary teachers in southwest England (63% female) to rate their level of job satisfaction and to rate 16 sources of job dissatisfaction that we adapted from the 1962 study. Teachers in 2007 rated their job satisfaction significantly lower and ordered the sources of job dissatisfaction significantly differently than did teachers in 1962. Whereas teachers in 1962 were most concerned with external sources of job dissatisfaction (e.g. salary, condition of buildings and equipment and poor human relations), teachers in 2007 expressed the most concern about factors relating to teaching itself (e.g. time demands and pupils' behaviour). The changes in sources of dissatisfaction hold true for male and female teachers, with no difference in rankings according to years of teaching experience.     

Contrast in usage of FCAT‐approved anatomical terminology between members of two anatomy associations in North America

Almost 12 years since the publishing of Terminologia Anatomica (TA) by the Federative Committee on Anatomical Terminology (FCAT), there has yet to be a unified adoption of FCAT‐recommended anatomical terms by North American anatomists. A survey was sent to members of the Human Anatomy & Physiology Society (HAPS) to compare the frequency of FCAT term usage with a previous study involving the American Association of Anatomists (AAA). The HAPS differed from AAA in being composed mostly of biologists (56.5%) who teach anatomy with only 18.3% of respondents having terminal degrees in anatomy. The survey included the same 25 sets of synonymic names for selected gross anatomical structures or related terms used for the AAA survey. Overall results indicate that the FCAT preferred term had the highest frequency of usage in only 40.0% of the survey questions, demonstrating 4% lower compliance than AAA respondents. Compliance with FCAT preferred terms ranged from 92.2% to 1.7% usage. When compared with AAA anatomists, there were reversals in predominant usage between FCAT and non‐FCAT terms for six sets of anatomical structures: HAPS respondents predominantly used non‐FCAT terms for adrenal gland (88.7%), antecubital fossa (57.4%), patellar tendon (65.2%), ligamentum capitis femoris (36.5%), while preferring the FCAT anterior circumflex humeral artery (45.2%) and anterior/posterior preferred over ventral/dorsal (41.7%). Almost 54% of HAPS anatomists were not familiar with the FCAT, nearly 21% higher than the AAA. Anat Sci Educ 3:25–32, 2010. © 2009 American Association of Anatomists.     

History effects on induced and operant variability

Two experiments evaluated history effects on induced and operant variability. College students typed three-digit sequences on a computer keyboard. Sequence variability was induced (by no reinforcement or variation- independent reinforcement) or reinforced (by variation- or repetition-dependent reinforcement). Conditions with induced and operant variability were presented according to a reverse between-groups design. In Experiment 1, we examined transitions from the variation or repetition contingencies to no reinforcement, and vice versa. In Experiment 2, the variation or repetition contingencies were followed or preceded by variation-independent reinforcement. The results showed that (1) a history of no reinforcement impaired operant variability learning; (2) induced variability levels were higher and lower after a history of reinforcement for variation and repetition, respectively; (3) repetition was more easily disrupted by no reinforcement and independent reinforcement than was variation; and (4) response variability and stability were a function of past and current reinforcement conditions. These results indicate that reinforcement history influences both induced and operant variability levels.     

Moving PISA Results into the Policy Arena: Perspectives on Knowledge Transfer for Future Considerations and Preparations

Evidence-based policies, decisions, and practices are highly valued and underachieved in the international mathematics and science education reforms. Many in the mathematics and science education research communities lament the lack of influence that research results have on the education profession, schools, and teaching. Academic research done in isolation of end-users—with the faint hope that teachers, politicians, and bureaucrats will access and utilise these results to inform curriculum, assessment, and instruction and to influence public policy—has not worked. Some funding agencies require dissemination of research and development results to the broader political and education communities; therefore, applicants agree to these requirements without fully realizing the breadth of these demands. However, to achieve such knowledge transfer requirements, researchers need to become more (a) aware of the needs, players, and processes of ‘speaking truth to power’; (b) active in knowledge transfer and influencing public policy; and (c) alert to values and normative premises of the policy makers. This article outlines the essential principles, barriers within the academic community, international efforts, and future considerations for knowledge transfer regarding international assessments. Specific articles on PISA 2000, 2003, and 2006 included in this special issue are used to illustrate these insights into verification of curricular influences, educational opportunity and equality, regional comparisons, and direct influence on policy.     

Effectiveness of school‐based psychotherapy: A meta‐analysis of dissertation research

A meta‐analysis was conducted with 65 school‐based psychotherapy and counseling dissertations over the last 10 years (1998–2008) to assess if a file‐drawer problem (i.e., studies conducted but not published that, as a whole, have different results than studies in the same area published) exists in the school‐based outcome literature. An overall mean effect size of 0.44 was found for 73 treatment interventions. This effect size is comparable to Prout and DeMartino's 1986 meta‐analysis conducted with published school‐based studies and approximately half a standard deviation smaller than Prout and Prout's 1998 meta‐analysis of school‐based intervention studies. A bias does appear to exist but seems to be smaller than the bias found in the general child and adolescent psychotherapy outcome literature. Most of the dissertation studies evaluated group interventions and used a cognitive–behavioral or skills training intervention. Skills training and interventions with elementary‐school students yielded the largest effect sizes. Comparisons of the current study with previous school‐based intervention meta‐analyses are discussed as are suggestions for future research. © 2010 Wiley Periodicals, Inc.     

Protective effects of photobiomodulation against resistance exercise-induced muscle damage and inflammation in rats

We investigated whether low-level laser therapy (LLLT) prior to or post resistance exercise could attenuate muscle damage and inflammation. Female Wistar rats were assigned to non-LLLT or LLLT groups. An 830-nm DMC Laser Photon III was used to irradiate their hind legs with 2J, 4J, and 8J doses. Irradiations were performed prior to or post (4J) resistance exercise bouts. Resistance exercise consisted of four maximum load climbs. The load work during a resistance exercise bout was similar between Control (non-LLLT, 225 ± 10 g), 2J (215 ± 8 g), 4J (210 ± 9 g), and 8J (226 ± 9 g) groups. Prior LLLT did not induce climbing performance improvement, but exposure to 4J irradiation resulted in lower blood lactate levels post-exercise. The 4J dose decreased creatine kinase and lactic dehydrogenase levels post-exercise regardless of the time of application. Moreover, 4-J irradiation exposure significantly attenuated tumor necrosis factor alpha, interleukin-6, interleukin-1β, cytokine-induced neutrophil chemoattractant-1, and monocyte chemoattractant protein-1. There was minor macrophage muscle infiltration in 4J-exposed rats. These data indicate that LLLT prior to or post resistance exercise can reduce muscle damage and inflammation, resulting in muscle recovery improvement. We attempted to determine an ideal LLLT dose for suitable results, wherein 4J irradiation exposure showed a significant protective role.     

Effects of inspiratory muscle training in professional women football players: a randomized sham-controlled trial

This study was conducted to determine the effects of inspiratory muscle training (IMT) on respiratory and peripheral muscles oxygenation during a maximal exercise tolerance test and on repeated-sprint ability (RSA) performance in professional women football players. Eighteen athletes were randomly assigned to one of the following groups: SHAM (n = 8) or IMT (n = 10). After a maximal incremental exercise test, all participants performed (on a different day) a time-to-exhaustion (Tlim) test. Peripheral and respiratory muscles oxygenation by near-infrared spectroscopy, breath-by-breath ventilatory and metabolic variables, and blood lactate concentration were measured. The RSA test was performed on a grass field. After a 6 week intervention, all athletes were reevaluated. Both groups showed increases in inspiratory muscles strength, exercise tolerance and RSA performance, however only the IMT group presented lower deoxyhemoglobin and total hemoglobin blood concentrations on intercostal muscles concomitantly to an increased oxyhemoglobin and total hemoglobin blood concentrations on vastus lateralis muscle during Tlim. In conclusion, these results may indicate the potential role of IMT to attenuate inspiratory muscles metaboreflex and consequently improve oxygen and blood supply to limb muscles during high-intensity exercise, with a potential impact on inspiratory muscle strength, exercise tolerance and sprints performance in professional women football players.
