Perceptions of elementary teachers on the instructional leadership role of school principals

In this research, elementary school principals＇ instructional leadership behavior was evaluated based on the perceptions of elementary school teachers. The research is believed to contribute to the development of instructional leadership behavior of elementary school principals for the development of school organization. A ＂semi-structured interview technique＂, one of the qualitative research methods in the literature was used in the research. The study group was made up of elementary school teachers working in Nigde, Turkey, during the 2008-2009 academic year. For the study sample, one teacher from each school was selected at random, resulting in group of twenty elementary school teachers. Based on the content analysis, five themes of instructional leadership behavior were found. These themes are： （1） determination of the school＇s purpose; （2） management of instruction; （3） evaluation of students; （4） support to teachers; and （5） creation of a regular learning-teaching environment.     

Age-related differences in acceleration, maximum running speed, and repeated-sprint performance in young soccer players

We investigated age-related differences in the relationships among acceleration, maximum running speed, and repeated-sprint performance in 61 highly trained young male soccer players (Under 14, n = 14; Under 16, n = 22; Under 18, n = 25). We also examined the possible influence of anthropometry (stature, body mass, fat-free mass) and biological maturation (age at peak height velocity) on performance in those three sprint-running qualities. Players were tested for 10-m sprint (acceleration), flying 20-m sprint (maximum running speed), and 10 × 30-m sprint (repeated-sprint performance) times. Correlations between acceleration, maximum running speed, and repeated-sprint performance were positive and large to almost perfect (r = 0.55-0.96), irrespective of age group. There were age-based differences both in absolute performance in the three sprint-running qualities (Under 18 > Under 16 > Under 14; P < 0.001) and when body mass and fat-free mass were statistically controlled (P < 0.05). In contrast, all between-group differences disappeared after adjustment for age at peak height velocity (P > 0.05). The large correlations among acceleration, maximum running speed, and repeated-sprint performance in all age groups, as well as the disappearance of between-group differences when adjusted for estimated biological maturity, suggest that these physical qualities in young highly trained soccer players might be considered as a general quality, which is likely to be related to qualitative adaptations that accompany maturation.     

Quantitative Assessment of Expression of Lactate Dehydrogenase and its Isoforms 3 and 4 may Serve as Useful Indicators of Progression of Gallbladder Cancer: A Pilot Study

We have studied the expression of lactate dehydrogenase and its isoforms in gall bladder cancer, cholelithiasis and chronic cholecystitis. Quantitative and qualitative assays of lactate dehydrogenase and its various isoforms were carried out in the blood sera of patients and healthy controls along with parallel estimation of various liver function test enzymes. Statistical analysis was done using the software Graph Pad Prism. Significantly high expression of lactate dehydrogenase along with alkaline phosphatase and total bilirubin (P ≤ 0.05) was observed in all the three clinical conditions as compared to controls. LDH showed an increasing trend from stage I to stage IV of GBC indicating a significant positive association with the disease progression. The levels of LDH 3 and 4 isoforms appeared significantly more elevated in GBC than cholelithiasis or chronic cholecystitis. We suggest that a careful estimation of total LDH and its isoforms 3 and 4 alone or along with alkaline phosphatase and total bilirubin during different clinical stages, like chronic cholecystitis, cholelithiasis and GBC, may prove to be a potentially useful biomarker in the prognostic management of gall bladder diseases, specifically GBC.     

Physical Education Curriculum Reform in Finland

The Finnish education system has received worldwide attention due to the top academic performance of Finnish school students. Physical education, as an integral part of the Finnish education curriculum, potentially contributes to the overall success. The purpose of this article is to summarize Finnish physical education reform during the past decades and to review and critique recent literature that has examined the effectiveness of Finnish physical education programs. This review concludes that physical education has a solid foundation in Finnish schools and that it enjoys strong support in Finnish society. Although physical education contact time has diminished across four decades, the current basic education reform has begun to allocate more time and funding for elementary and middle school physical education. The literature review, however, revealed limited evidence on the effectiveness of physical education programs. In the future, robust studies are needed to provide evidence of the effectiveness of physical education. It is likely that with rigorous research evidence, the current efforts to allocate more time for physical education should be more easily justified and supported.     

Use of on-line databases by faculty members and research scholars of Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), New Delhi (India): A survey

The study is focused on finding out the level of use of on-line databases by faculty members and research scholars of the Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), Delhi (India). Both are Central Universities and are funded by the University Grants Commission (UGC). A well-structured questionnaire was administered to faculty members and research scholars of the JNU and JMI to collect data regarding the use of on-line database. The survey reveals that all of the faculty members and research scholars are aware of the availability of on-line databases and largely use them for reference purposes in their research work and studies. The degree of usefulness and utilization of on-line databases is high among the universities' faculty members and research scholars. The survey further reveals that the respondents from both universities are aware of the search options for accessing on-line databases. It is also found that a large number of respondents of JNU and JMI are using field searching and Boolean operators to access information from on-line databases.     

Electronic information sharing in local government authorities: Factors influencing the decision-making process

Local Government Authorities (LGAs) are mainly characterised as information-intensive organisations. To satisfy their information requirements, effective information sharing within and among LGAs is necessary. Nevertheless, the dilemma of Inter-Organisational Information Sharing (IOIS) has been regarded as an inevitable issue for the public sector. Despite a decade of active research and practice, the field lacks a comprehensive framework to examine the factors influencing Electronic Information Sharing (EIS) among LGAs. The research presented in this paper contributes towards resolving this problem by developing a conceptual framework of factors influencing EIS in Government-to-Government (G2G) collaboration. By presenting this model, we attempt to clarify that EIS in LGAs is affected by a combination of environmental, organisational, business process, and technological factors and that it should not be scrutinised merely from a technical perspective. To validate the conceptual rationale, multiple case study based research strategy was selected. From an analysis of the empirical data from two case organisations, this paper exemplifies the importance (i.e. prioritisation) of these factors in influencing EIS by utilising the Analytical Hierarchy Process (AHP) technique. The intent herein is to offer LGA decision-makers with a systematic decision-making process in realising the importance (i.e. from most important to least important) of EIS influential factors. This systematic process will also assist LGA decision-makers in better interpreting EIS and its underlying problems. The research reported herein should be of interest to both academics and practitioners who are involved in IOIS, in general, and collaborative e-Government, in particular.     

Improving Design Understandings and Skills through Enhanced Metacognition: Reflective Design Journals

The main aim of this study was to investigate and discover whether going through the process of reflection by keeping reflective design journals (RDJ) enhances architecture students’ metacognition and whether this enhanced metacognition improves their design understandings and skills. The study was a mixed‐methods design and utilised content analysis method to identify the metacognitive actions of the participants. The study also investigated participants’ attitudes towards RDJs and their views regarding the effect of enhanced metacognition on their design understandings and skills. Twenty college students registered to an undergraduate course offered by the department of Architecture participated in the research. The findings of the study revealed that by writing in their RDJs, participants were able to progressively enhance their metacognitive skills and performed several metacognitive actions by using the four main metacognitive strategies: awareness, organisation and planning, monitoring, and evaluation. The results also disclosed that participants found RDJ keeping exceptionally effective and stated that their enhanced metacognition improved their design understanding and abilities.     

Children of the sug: a study of the daily lives of street children in Khartoum, Sudan, with intervention recommendations

OBJECTIVES: The study examines street children's daily lives in Khartoum, Sudan to recommend ways to improve their conditions and to successfully assist them off the streets. METHODS: In 2000-2001, eight researchers conducted participant observation for 7 weeks; 20 groups of children engaged in role-plays and drawing activities; over 500 children participated in qualitative group and individual interviews; and 872 current and former street children were surveyed. RESULTS: Approximately half of children were 14 years old or younger. Daily life focused on eating, sucking glue-soaked rags, obtaining money, and sometimes movies or games; many children valued their freedom and relatively abundant food on the streets. Boys engaged in odd jobs, and sometimes theft, begging, or sex work. Girls had fewer work opportunities and primarily obtained money through begging and sex work. Almost half of children saw their families weekly. Children belonged to same-sex groups of common geographic origin, which shared food, shelter, and care when sick; boys' group leaders could be both protectors and aggressors. Most girls had a boyfriend who financially assisted and protected her. Girls frequently were raped by street boys, police, or other men. Children feared routine capture, beating and incarceration by authorities. Former street children were housed in large camps where abuse was common, or costly small residencies. CONCLUSIONS: Street-based services to improve children's health and safety are urgently needed. Re-integration programs may help large numbers of children voluntarily and permanently leave the streets. Advocacy campaigns and collaborative efforts with the police, judiciary and legislature should be intensified. PRACTICE IMPLICATIONS: The paper highlights important challenges facing street children in Khartoum, and provides specific recommendations for how they might be better assisted while on the streets and successfully helped off of the streets through community re-integration, rather than current (1) large-scale beating and incarceration by government authorities, or (2) small-scale and costly residential housing by NGOs. The findings have already been used in a sustained advocacy campaign that has resulted in a number of positive legislative changes for street children, such as parliamentary endorsement of a new bill that improves street children's legal status.
