Physical activity (PA) is important in ensuring a healthy population. It is dependent on various socio-demographic (SD) factors, such as age, gender, employment and marital status. A limited number of studies have investigated the relationship between SD factors and PA but research exploring this relationship from the perspective of gated and non-gated neighbourhoods is scarcer. Therefore, the objective of this study is to investigate the relationship between SD factors and PA variables in gated and nongated neighbourhoods in Karachi Pakistan. Results of the independent sample t-test and Pearson chi-square showed that young and single people do more sports activities in gated neighbourhoods. Women, unemployed people and public transport users walk more in non-gated neighbourhoods. In conclusion, future neighbourhoods should have more pedestrian friendly areas and a larger number of PA facilities, rather than building more walls and gates. 相似文献

Objective
To determine the prevalence of five forms of abuse/neglect during childhood and adolescence in a group of schizophrenic patients with a history of violence.Methods
Twenty-eight patients hospitalized in a highly secured psychiatric unit were included. Abuse and neglect during patients’ growth were evaluated with the childhood trauma questionnaire (CTQ). History of substance abuse (consumption of cannabis, and/or alcohol, and/or heroin, and/or cocaine during the year that preceded the hospitalization), incarceration, and death of a close parent were also collected.Results
We found that 46.4% of patients experienced at least 1 form of abuse and/or neglect during childhood and 21.4% of them had experienced more than 2 forms of abuse and/or neglect. The 2 most frequent forms of neglect and abuse were physical abuse (39.3%) and emotional neglect (17.9%). History of substance abuse was found for cannabis (57.1%), alcohol (57.1%), and cocaine and/or heroin (35.7%). We found that 42.8% of patients had 1 close relative who had died during their growth and that 41.6% of these deaths were violent.Conclusion
It appears important to systematically search for and assess a history of abuse and neglect during growth in schizophrenic patients with a history of violence, in order to offer specific treatments for this group of patients. 相似文献44.
We investigated Iranian secondary-school English teachers’ interpersonal behaviour with a validated culturally-adaptive Iranian version of the Questionnaire on Teacher Interaction. Data were collected from 971 Iranian secondary-school students (398 students participated in the pilot study and 573 students in the main study) and 55 Iranian secondary-school English teachers (23 teachers participated in the pilot study and 32 in the main study). The construction of the instrument started with an open-ended questionnaire followed by semi-structured interviews to prepare items for the questionnaire. Next, expert judgement, pilot administration of the questionnaire and statistical analyses ensured its reliability and construct validity before final administration of the questionnaire to the main participants followed. The study supported the validity and reliability of the questionnaire and confirmed its usability in the Iranian secondary-school context. Furthermore, the results indicated that the students perceived their English teachers as being Tolerant and Authoritative, showing higher degrees of friendship, leadership and understanding behaviour and relatively low levels of uncertain and dissatisfied behaviour. The results showed a discrepancy between students’ perceptions of actual and ideal teacher interpersonal behaviour. Also students’ perceptions of their actual teachers’ interpersonal behaviour were significantly different from those of the teachers’ self-perceptions. One important implication of this study is that the QTI can be used in secondary-school contexts as a valuable feedback instrument to encourage teachers to reflect on their performance and improve their interpersonal behaviour as a part of their professional development. 相似文献

This paper gives the rationale and a draft outline for a framework for education to teach epistemic insight into schools in England. The motivation to research and propose a strategy to teach and assess epistemic insight followed research that investigated how students and teachers in primary and secondary schools respond to big questions about the nature of reality and human personhood. The research revealed that there are pressures in schools that dampen students’ expressed curiosity in these types of questions and limit their developing epistemic insight into how science, religion and the wider humanities relate. These findings prompted the construction of a framework for education for students aged 5–16 designed to encourage students’ expressed interest in big questions and develop their understanding of the ways that science interacts with other ways of knowing. The centrepiece of the framework is a sequence of learning objectives for epistemic insight, organised into three categories. The categories are, firstly, the nature of science in real world contexts and multidisciplinary arenas; secondly, ways of knowing and how they interact; and thirdly, the relationships between science and religion. Our current version of the Framework is constructed to respond to the way that teaching is organised in England. The key principles and many of the activities could be adopted and tailored to work in many other countries. 相似文献

Progress in education in Afghanistan since the fall of the Taliban has been described as ‘fragile, limited in reach, depth and uncertainty of sustainability' [UNICEF. 2013. Basic Education and Gender Equality: Afghanistan. United Nations International Children's Emergency Fund. http://www.unicef.org/afghanistan/education_2206.htm]. This is particularly true for Afghan women participating in higher education, within a culture that remains resistant to women's education. This article documents the views and attitudes of Afghan women who have sought to gain a higher education, within a context where only 5% of the Afghan population attends university, and less than 20% of university students are female [The World Bank. 2013. World Development Indicators: Poverty Headcount Ratio at National Poverty Lines. The World Bank Group. http://data.worldbank.org/country/afghanistan]. It is an attempt to listen to the voices of Afghan women to ascertain what they see as the best ways to improve their educational outcomes. Findings illustrate that while progress has been made in enabling a small percentage of women to pursue higher education, there are still significant and enduring obstacles for Afghan women seeking such a path. 相似文献

In the present work, the potential of acaricidal activity of chamomile flowers' extract was studied against engorged Rhipicephalus annulatus tick under laboratory condition. For this purpose, the engorged females of Rhipicephalus annulatus were exposed to two-fold serial dilutions of chamomile flowers' extract (0.5%, 1.0%, 2.0%, 4.0% and 8.0%) using "dipping method" in vitro. The engorged ticks were immersed in different plant dilutions (five ticks for each dilution) for 1 min and they were imme-diately incubated in separate Petri dishes for each replicate at 26 °C and 80% relative humidity. Mortality rate for each treatment was recorded 5 d after incubation. The mortality rate caused by different dilutions of chamomile flowers' extract ranged from 6.67% to 26.7%, whereas no mortality was recorded for non-treated control group. The mass of produced eggs varied from 0.23 g (in 8.0% solution) to 0.58 g (in control), with no statistical differences between the treatments and control (P>0.05). Also the chamomile flowers' extract in highest concentration used (8.0%) caused 46.67% failure in egg laying in engorged females while no failure was observed for non-treated control group. Macroscopic observations indicated that in effective concentrations of plant (4.0% and 8.0%), patchy hemorrhagic swelling appeared on the skin of treated ticks. The results presented for the first time in this study imply that chamomile may be considered as a promising plant for biocontrol of cattle fever tick disease in the field condition. 相似文献

This paper examines the discourses and modes of representation embodied in educational historiography from the 1970s to the present and their implications for intellectual identity construction in SA. The paper shows how the theoretical foundations of the liberal and Afrikaner nationalist discourses, which vacillated between race and ethnicity, shifted to social class and gender in radical and neo‐Marxist discursive formations of the 1980s. It highlights how the decline of radical scholarship has resulted in a synthesis of constructivist and postmodernist discourses that privilege nation‐building, identity and cultural diversity after apartheid within a predominantly neo‐liberal paradigm. It argues that the transition to post‐apartheid education came to be thought about within a horizon of possibilities different from the rigid paradigmatic tradition of the short‐lived neo‐Marxist school of the 1970s and 1980s. 相似文献

Detection of proteins and nucleic acids is dominantly performed using optical fluorescence based techniques, which are more costly and timely than electrical detection due to the need for expensive and bulky optical equipment and the process of fluorescent tagging. In this paper, we discuss our study of the electrical properties of nucleic acids and proteins at the nanoscale using a nanoelectronic probe we have developed, which we refer to as the Nanoneedle biosensor. The nanoneedle consists of four thin film layers: a conductive layer at the bottom acting as an electrode, an oxide layer on top, and another conductive layer on top of that, with a protective oxide above. The presence of proteins and nucleic acids near the tip results in a decrease in impedance across the sensing electrodes. There are three basic mechanisms behind the electrical response of DNA and protein molecules in solution under an applied alternating electrical field. The first change stems from modulation of the relative permittivity at the interface. The second mechanism is the formation and relaxation of the induced dipole moment. The third mechanism is the tunneling of electrons through the biomolecules. The results presented in this paper can be extended to develop low cost point-of-care diagnostic assays for the clinical setting. 相似文献

The evolvable multiprocessor (EvoMP), as a novel multiprocessor system-on-chip (MPSoC) machine with evolvable task decomposition and scheduling, claims a major feature of low-cost and efficient fault tolerance. Non-centralized control and adaptive distribution of the program among the available processors are two major capabilities of this platform, which remarkably help to achieve an efficient fault tolerance scheme. This letter presents the operational as well as architectural details of this fault tolerance scheme. In this method, when a processor becomes faulty, it will be eliminated of contribution in program execution in remaining run-time. This method also utilizes dynamic rescheduling capability of the system to achieve the maximum possible efficiency after processor reduction. The results confirm the efficiency and remarkable advantages of the proposed approach over common redundancy based techniques in similar systems. 相似文献
