When considering the management of student behaviour issues, a substantial body of literature, as well as logical common sense, points to the advantages of whole school policy over the individual efforts of teachers. Less is known, however, about the direct or indirect role school leadership plays in the development of well-implemented whole school behaviour management (WSBM) systems and policy in primary schools. This article explores elements of leadership practice likely to promote well-implemented WSBM, using an initial framework developed from related literature and applying it in a study of primary schools. The sample comprised 52 staff members from 31 government and non-government primary schools in 5 states and territories of Australia. Data were obtained from interviews which sought to gather information about how well each school’s WSBM was implemented. Results confirmed the theorised framework of leadership practices that encourage well-implemented WSBM. The article concludes with implications for future research and school leadership. 相似文献

In this paper, using the energy concept, the control of traffic flow by traffic lights on an over-saturated single intersection is addressed. By regarding the flow entry of vehicles as the energy stored in the system, we show that the dissipative system theory can be applied. As a result, a state feedback control law is found in terms of the solution of an associated dissipation equation that renders the system non-accumulative, i.e., to get out of the over-saturation situation. The results of the simulations indicate that our control strategy guarantees a high degree of control benefit. 相似文献

A growing number of studies have demonstrated that purpose in life is associated with positive outcomes among adolescents and young adults. The college years represent an important period of both personal and professional growth, including purpose in life. Supportive relationships may play a critical role in the identification and pursuit of purpose. Relationships with mentors, for example, have been linked with purpose among adolescents. The present study examined whether mentoring relationships were linked with purpose among college students (N = 194) from three institutions across the United States. Both aspects of quality (relational health) and quantity (i.e., number of mentors) were examined as predictors of purpose. Students who had at least one mentor reported higher levels of purpose compared to students with no mentors. Among students with at least one mentor, quality of mentoring was significantly associated with a greater commitment to purpose, while the number of mentors was not associated with commitment to purpose. Results are discussed in the context of practical applications regarding student success and purpose formation in higher education settings. 相似文献

Counterspaces for women of color in STEM higher education: Marginal and central spaces for persistence and success 下载免费PDF全文
Counterspaces in science, technology, engineering, and mathematics (STEM) are often considered “safe spaces” at the margins for groups outside the mainstream of STEM education. The prevailing culture and structural manifestations in STEM have traditionally privileged norms of success that favor competitive, individualistic, and solitary practices—norms associated with White male scientists. This privilege extends to structures that govern learning and mark progress in STEM education that have marginalized groups that do not reflect the gender, race, or ethnicity conventionally associated with STEM mainstream success, thus necessitating spaces in which the effects of marginalization may be countered. Women of color is one such marginalized group. This article explores the struggles of women of color that threaten their persistence in STEM education and how those struggles lead them to search out or create counterspaces. It also examines the ways that counterspaces operate for women of color in STEM higher education, particularly how they function as havens from isolation and microaggressions. Using a framework of Critical Race Theory (CRT) and intersectionality theory and drawing on interview data from 39 women of color about their STEM higher education experiences, we describe five ways in which counterspaces operate: in peer‐to‐peer relationships; mentoring relationships; national STEM diversity conferences; STEM and non‐STEM campus student groups; and STEM departments. Whereas most research has discussed counterspaces as racially or ethnically homogeneous social groups of peers at the margins, our research found that counterspaces vary in terms of the race/ethnicity, gender, and power levels of participants. We found that counterspaces can be physical settings, as well as conceptual and ideological. Additionally, we identified counterspaces both at the margins and at the center of STEM departments. Thus, our research expands the existing understanding of the types and functions of counterspaces and broadens the definition of what locations can be and should be considered counterspaces. © 2017 The Authors.

Developed in response to concerns that too few students were enrolling and succeeding in postsecondary education, early college high schools are small schools that blur the line between high school and college. This article presents results from a longitudinal experimental study comparing outcomes for students accepted to an early college through a lottery process with outcomes for students who were not accepted through the lottery and enrolled in high school elsewhere. Results show that treatment students attained significantly more college credits while in high school, and graduated from high school, enrolled in postsecondary education, and received postsecondary credentials at higher rates. Results for subgroups are included. 相似文献

ABSTRACT Athlete Biological Passport (ABP) is an indirect approach, implemented by WADA, aimed at detecting blood manipulation based on abnormal changes in haematological markers. Cases report the use of hyperhydration as masking method during anti-doping urine sample collection which could potentially mask suspicious fluctuations on ABP profiles. This study investigated the hyperhydration effect on haemoglobin concentration, reticulocyte percentage and OFF-hr score (an algorithm based on haemoglobin concentration and reticulocyte percentage), with and without recombinant human erythropoietin (rHuEPO) administration. A five-week clinical study performed; Baseline and rHuEPO Phase. Water and a sports drink were used as hyperhydration agents. To examine the hyperhydration effect on the normal ABP profile per volunteer, hyperhydration was implemented at 0, 24 and 48 hours during the baseline. During the rHuEPO phase, volunteers received Epoetin beta (3000 IU) with hyperhydration to be implemented at 0, 24 and 48 hours after drug administration. Blood and urine samples were collected and analysed according to WADA guidelines. No significant effect on ABP markers was observed due to hyperhydration at any time during the study. Pre- and post-hyperhydration data were not statistically different compared to individual baseline data. In conclusion, hyperhydration does not affect the ABP haematological markers under the examined conditions. 相似文献

In Canada’s first-ever strategy, international education (IE) is linked to immigration policy with international students (IS) recruited as ‘ideal’ immigrants. This paper engages in policy sociology and Ball's concepts of 'policy as text' and 'policy as discourse' (10). It follows three stages of critical policy discourse analysis. The first a simple tally of the most commonly used words/phrases in the Strategy; the second analyses it using Van Leeuwen’s framework and the third presents results from a study on the perception and experiences of IS, exposing the gap between policy rhetoric and practice. The paper concludes that critical discourse analysis is a powerful tool to uncover policy values/ideologies, identify legitimation strategies and reveal perpetuation of power relations/status quo within Canadian society. 相似文献

In this paper we examine the leadership and management of multi-university collaborations funded by national teaching grants. The paper commences with a review of literature relating to stages of project development, key operational issues, impediments to collaboration and the leadership and management of teaching grant collaborations. Finally, we explore critical success factors in teaching grant collaborations from three perspectives – those of leader, manager and team member. 相似文献
