Examining the structure of vocational interests in Turkey in the context of the personal globe model

The structural validity of the Personal Globe Inventory-Short (PGI-S: Tracey in J Vocat Behavi 76:1–15, 2010) was examined in a Turkish sample of high school and university students. The PGI-S measures eight basic interest scales, Holland’s (Making vocational choice, Prentice-Hall, Englewood Cliffs, 1997) six types, Prediger’s (J Vocat Behav 21:259–287, 1981) people/things, data/ideas dimensions, and prestige. After adapting the original PGI-S items into Turkish (PGI-S-T), the inventory was administered to high school students (N = 605) and university students (N = 359). The fit of Holland’s RIASEC and the PGI eight type model were examined separately using the randomization test of hypothesized order relations. Results indicated a strong fit for both the eight type and the RIASEC model. Expected significant differences were found between PGI-S-T subscales across gender and age. The results support the structural validity of the adapted PGI-S-T in a Turkish sample.     

The generalizability of student ratings of instructors: Item specificity and section effects

A number of recent studies have used generalizability theory to examine the dependability of student ratings of instruction. This study extends this line of research by examining the consistency of ratings between different sections of a course taught in a given semester by the same instructor, and by comparing the performance of global- and attribute-type instructor rating items. Five samples of physics instructors, varying in size from 5 to 12 instructors, were rated by their students on a form containing two global and eight attribute items. Each instructor taught two sections of a course. The study found that the section effect was small (ratings of instructors were consistent across different sections of the same course), and that the generalizability of ratings was substantially influenced by item specificity. For summary purposes, one global item seemed sufficient.     

Effects of auditory perception training on reading achievement

This study investigated the effect of an auditory training programme with backward readers who were also deficient in one or more auditory perceptual subskills. Thirty subjects were randomly assigned to one of three groups. The experimental group received a nine hour taped programme devised by the experimenter and designed to teach the skills of auditory discrimination, memory, analysis and synthesis and auditory-visual integration. The comparison group listened to stories on tape for the same duration as the experimental group, while the third group served as a control merely being tested at the beginning and at the end of the experiment. It was found that although the training programme significantly improved the performance of the experimental group over the other two groups on a total auditory perceptual test, there was no corresponding improvement in reading, on word recognition or comprehension tests. The particular auditory subskills which appeared amenable to training were auditory discrimination (rhyme) and auditory synthesis (blending and closure).     

Action learning as invigoration

The present account of action learning describes its adoption for pragmatic reasons by the University of the Third Age (U3A). The reason for the existence of this movement is the education of retired people. The account seeks to explain why the action learning method spread from one local U3A to another and across it to other local U3As. The case is that the directness of action and its power to involve people brought action learning a following among persons so that they could carry out specific activities even though the persons concerned would never have heard of the term action learning. The successful use of the method fed through into the users' minds and brought about a mode of thought, one which unconsciously was capable of extension into an outlook that could be applied to a variety of situations. Thus two types of learning took place: that between U3As and that within U3As.     

Do primary students understand how pregnancy can occur? A comparison of students in Jakarta,West Java,West Nusa Tenggara and South Sulawesi,Indonesia

In Indonesian primary schools, sex education is implicitly integrated into various related subjects, such as science, biology, social studies and religion. The technical facts of ovulation and sperm are mentioned in biology, although little or no connection is made between this process and sexual intercourse. By the end of primary school, therefore, children are likely to have a poor understanding of how pregnancy can occur. Given that young girls at this age have already experienced or will soon experience menarche, and given the increasing trend towards delaying the age at marriage in Indonesian society, this lack of knowledge places young people at risk of various negative consequences, including unwanted pregnancy. In this paper, we investigate the level of understanding regarding human reproduction amongst 1762 students attending the last year of primary school, distributed across 32 different schools in Indonesia. Despite the fact that all schools follow a national curriculum, our results reveal widespread variability in the students' comprehension of how pregnancy can occur. In particular, students attending Islamic religious schools and those in less developed provinces of Indonesia appear to have a much poorer understanding of the link between sexual intercourse and conception.     

Comparative aerodynamics of synthetic badminton shuttlecocks

Badminton synthetic shuttlecocks are known to have significantly different aerodynamic behaviours compared to feathered shuttlecocks due to the difference in designs and use of materials. Given the fragility of avian feathers used for feathered shuttlecocks and the constantly increasing cost of purchase, the interest to assess the current synthetic shuttlecock design as a feasible alternative has re-emerged. The single-piece injection-moulded synthetic shuttlecock has been the mainstream design for the past 50 years; however, little evidence has supported that the design mimics the aerodynamics of feathered shuttlecocks. Recently, a two-part skirt design has emerged proclaiming to have surpassed its synthetic predecessor in regard to matching the aerodynamics of feathered shuttlecocks. In the current study, two different synthetic designs (injection-moulded vs two-part skirt) were benchmarked against a feathered shuttlecock. A wind tunnel test was conducted between 30 and 145 km/h. The drag coefficients of both synthetic shuttlecocks were similar to the feathered shuttlecock up to 105 km/h. Thereafter, the drag coefficient of the injection-moulded design dropped from 0.62 to 0.5 and showing no signs of levelling at speeds over 105 km/h, while the coefficient for two-part skirt design stabilised at approximately 0.55. It was concluded that the two-part skirt design better mimicked the aerodynamics of the feathered shuttlecock.     

Adolescent risk factors for child maltreatment

We investigate adolescent risk factors, measured at both early and late adolescence, for involvement in child maltreatment during adulthood. Comprehensive assessments of risk factors for maltreatment that use representative samples with longitudinal data are scarce and can inform multilevel prevention. We use data from the Rochester Youth Development Study, a longitudinal study begun in 1988 with a sample of 1,000 seventh and eighth graders. Participants have been interviewed 14 times and, at the last assessment (age 31), 80% were retained. Risk factors represent 10 developmental domains: area characteristics, family background/structure, parent stressors, exposure to family violence, parent–child relationships, education, peer relationships, adolescent stressors, antisocial behaviors, and precocious transitions to adulthood. Maltreatment is measured by substantiated reports from Child Protective Services records. Many individual risk factors (20 at early adolescence and 14 at later adolescence) are significantly, albeit moderately, predictive of maltreatment. Several developmental domains stand out, including family background/structure, education, antisocial behaviors, and precocious transitions. In addition, there is a pronounced impact of cumulative risk on the likelihood of maltreatment. For example, only 3% of the youth with no risk domains in their background at early adolescence were involved in later maltreatment, but for those with risk in 9 developmental domains the rate was 45%. Prevention programs targeting youth at high risk for engaging in maltreatment should begin during early adolescence when risk factors are already at play. These programs need to be comprehensive, capable of addressing the multiple and interwoven nature of risk that is associated with maltreatment.
