Positive teacher–student relationships go beyond the classroom,problematic ones stay inside

The authors voice teachers' perceptions of their interpersonal experiences with students in both positive and problematic relationships. Interview data from 28 teachers were examined by coding utterances on teacher and student interactions. Results indicate that teachers defined the quality of the relationship mostly by the level of communion (friendly vs. hostile), instead of by the level of agency (in control vs. powerless). Analyses of mentioned teacher and student behavior show a friendly interactional pattern for positive relationships and a hostile pattern for problematic ones. In teachers' perceptions, positive and problematic relationships also differed in context where encounters take place and topic of talk. Contrary to interactions in problematic relationships, encounters in positive relationships were mostly situated outside the classroom context and conversations during these encounters covered a wide range of topics. Implications for teacher education programs are discussed.     

Effect of different swim caps on the assessment of body volume and percentage body fat by air displacement plethysmography

Isothermal air trapped in scalp hair generates an underestimation of body volume when it is measured by air displacement plethysmography. The aim of this study was to examine the effect of wearing different types of swim caps on the measurement of body volume and percentage body fat by air displacement plethysmography. It was hypothesized that wearing a silicone swim cap would more thoroughly compress scalp hair compared with a lycra swim cap, yielding higher estimates of body volume and percent body fat. Thirty female participants aged 25.7 ± 6.4 years were measured in random order when wearing no swim cap, a lycra swim cap or a silicone swim cap. For the no-cap versus lycra cap condition, the mean bias for body volume was -0.579 ± 0.380 litre (limits of agreement: -1.340 to 0.181 litre) and for percent fat -4.9 ± 3.1% fat (limits of agreement: -11.2 to 1.3% fat) (P < 0.05). For the silicone versus lycra condition, the mean bias for body volume was 0.137 ± 0.099 litre (limits of agreement: -0.062 to 0.335 litre) and for percent fat 1.2 ± 0.9% fat (limits of agreement: -0.5 to 2.9% fat) (P < 0.05). In conclusion, attention should be paid to optimal compression of isothermal air trapped in scalp hair when using air displacement plethysmography. The present results suggest that this compression may be more thorough when wearing a silicone swim cap.     

Cognitive Methods in Counselor Training

With the renewed interest in the role of cognition in counselor training, numerous studies examining this phenomenon have emerged. This article reviews existing literature relevant to cognitive issues in training. The effects of various cognitive attributes such as conceptual level and cognitive style are discussed. Similarly, the impact of various cognitive training strategies on trainee performance are examined, such as modification of trainee cognitions to enhance skill generalization and cognitive restructuring techniques to alter maladaptive cognitions of trainees. In addition, methodological issues that have served to limit research activity are addressed. Brief recommendations are offered for future research and training efforts.     

How Should Quality Management be Taught?

Assessment of the power performance of racing cyclists

A 30‐s ‘all‐out’ power protocol was studied in four groups of racing cyclists including internationals (n = 8), Category 1 (n = 10), Category 2 (n = 15) and Category 3 (n = 11). Following warm‐up each subject completed five trials interspersed by 3 min of low intensity exercise on an ergowheel racing cycle ergometry system at a power output of 15 W kg^–1 body weight, generated at 130 rev min^–1. Temporal indices of performance included delay time (DT) to achieve the power criterion, total time (TT) of the maintenance of the power criterion and the ratio of TT/DT. ‘Explosive’ leg strength was assessed from a vertical jump. The results indicated that international and Category 1 cyclists had lower DT (2.2 ± 0.1s and 2.1 +0.0s, respectively; P<0.05), higher TT (28.1 ±0.7s and 27.0+0.7s, respectively; P<0.05) and elevated TT/DT (12.8 and 12.9, respectively; P<0.01). ‘Explosive’ leg strength was also higher (P<0.05) in the internationals than in the other groups of cyclists. The protocol provides a sport‐related method for the assessment of short term endurance performance ability in racing cyclists which may be of value in identifying the anaerobic capability of individual cyclists.     

Kindergarten child care experiences and child achievement and socioemotional skills

Young children's experiences outside of both home and school are important for their development. As women have entered the labor force, child care has become an increasingly important context for child development. Child care experiences prior to school entry have been well-documented as important influences on children's academic and socioemotional development. However, less is known about the importance of non-parental, out-of-school care for young school-age children's development. Using a nationally representative sample of kindergartners (n = 16,888), this study examined the relationship between child care experiences during the kindergarten year and children's academic and socioemotional skills. Given that the amount of time available for child care is by definition related to the type of kindergarten a child attends, differences in the relationship between child care and child development were explored separately by full- and part-day kindergarten. Results showed that across both types of kindergarten, more hours of center care during the kindergarten year were associated with small improvements in math test scores for all children. Any center child care during the kindergarten year was associated with increased problem behavior and decreased prosocial skills, even after accounting for a large number of confounding factors. Differences by family income and child gender were also investigated. Implications for policy and practice are discussed.     

Linking theory and practice: teacher research in history and geography classrooms

The impact of scholarly research in education on the educational practice in secondary school is low. Academics examine problems that teachers in school perceive as irrelevant, want to publish in peer-reviewed journals instead of disseminate their work, and aim at generalizing insights rather than improving school practice. Teacher research might be a way to link educational academic research and teaching practice aiming at furthering professionalism in teaching, improving teaching practice and extending the knowledge base on teaching and learning. Four experienced secondary school teachers systematically investigated their classes, guided by a supervisor. Their materials as well as formal and informal communication with their supervisor and with each other were analysed. Related to their research projects, these teachers reported significant changes in their understanding of student learning and their teaching. They took different perspectives on teaching, looked at alternative solutions for problems, and reflected more deeply on their own teaching as well as teaching of their colleagues. Although each of them published an article in a peer-reviewed journal, they reported difficulties with extending the knowledge base on teaching and learning. Not only did they rarely share results with their colleagues in school because they were perceived as external researchers, they also struggled with writing journal articles and coping with peer reviews. We discuss the value of situated generalization as one of the implications and discuss how teacher research could lead to a new in-between research practice, linking theory and practice, and researchers and teachers.     

Validity of acute phase proteins and trace metals as adjuncts in viral hepatitis A and B

The level of seven acute phase proteins was estimated together with copper and zinc in two groups of 15 children each suffering from hepatitis A (HAV) or Hepatitis B (HBV). The mean concentration of α-1 antitrypsin, α-2 macroglobulin, ceruloplasmin, C3 and copper was increased uniformly in both the types of viral hepatitis. α-1 acid glycoprotein, haptoglobin and zinc levels were decreased in both the infections. A significant decrease in albumin level was observed in HAV while the decrease was not significant in HBV. All the paramenters were repeated after one month on the day of discharge following the disappearance of clinical signs and symptoms wherein the haptoglobin level returned to normal in HAV. No change was observed in the level of other acute phase proteins. The level of the trace elements returned to normal. The observed increase in the levels of acute phase proteins at the onset does not seem to have any significant relation to the subsequent course of the disease. However, the level of acute phase proteins and other biochemical parameters may indicate a delayed biochemical recovery phase in conjunction with the underlying hepatic pathological changes in the course of viral hepatitis in spite of clinical recovery.
