Research has shown that both historically and currently there has been sex-differentiated staffing in American public schools, with a disproportionate number of female teachers at the elementary level. Concern long has been expressed regarding the impact this might have on the sex-role development of American children and the perpetuation of stereotypic staffing patterns. This article supports the hypothesis that psychologically androgynous individuals might be more likely than masculine or feminine individuals to base teaching level choice upon individual preference without regard for its stereotype as more appropriate for one sex than the other. Data collected from preservice teachers at Washington State University support this hypothesis. It was found that while feminine females were more apt to choose the elementary teaching level, masculine males were more apt to choose secondary teaching. In comparison, androgynous preservice teachers of both sexes were as likely to choose the elementary as secondary teaching level.  相似文献

The word “empowerment” is associated with several different and fundamentally inadequate paradigms. This paper presents an alternative, empowering view of empowerment. The essence of empowerment is increasing the behavior potential of persons, individually and in groups and organizations. Behavior potential is not some abstract concept of “what a person might do if” Instead, it is the totality of behaviors that are actually available to a given person in a given environment. These behaviors do not occur in a vacuum; behavior potential is the intersection of the person's behavioral productions with the organization's expectations and permissions. An individual is empowered to the extent that he or she possesses a rich repertoire of behaviors and is expected and permitted to make full use of this repertoire by the organization.  相似文献

It is clear from the extant literature that gender inequities exist in a myriad of ways in science classrooms. Past research, however, has been conducted solely from researchers' observations and has neglected to investigate students' awareness of and reactions to their own experiences. Hence, this study focused on students' perceptions of gender differences in instructional activity and talk about that activity in physics and honors physics classes. Data analysis showed that although teachers may be unaware of gender inequities, students of both sexes are not unaware of such inequities. Females explained their fears of offering their opinions and participating in activities like labs and small-group or whole-class discussions. Differential language patterns were found for males and females, particularly when discussion was structured and rewarded for refutation. Explanations are offered for these disparities and suggestions are given for addressing gender bias in science classrooms. It has been well documented that science classrooms are not gender fair (Bazler & Simonis, 1991; Bianchini, 1993; Tobin, 1988). Teachers, texts, and the forms of instruction they perpetuate contribute to gender inequities in science instruction. For example, research tracing changes in science textbooks over time has shown that current texts have failed to eliminate barriers to women in science (Bianchini, 1993). Science textbooks are criticized for their unequal treatment of genders, with illustrations, photos, and texts of males far outnumbering those of females, despite the approximate 50/50 male/female ratio of our population (Bazler & Simonis, 1991). In addition to the proclivity of science textbooks to favor males, researchers speculate that the tendency for boys to achieve higher than girls in science may be a result of more opportunity to engage in academic tasks (Tobin & Garnett, 1987). Their behavior shows that teachers have differential expectations for students' responses in activities like teacher-led discussion. In teacher-led, whole-class discussion, boys are spoken to more frequently and are asked more higher-order questions (Becker, 1991; Hall & Sadler, 1982). Teachers in science classrooms elaborate more on males' responses than females' responses in large-group discussion of scientific concepts (Jones & Wheatley, 1990). © 1996 John Wiley & Sons, Inc.  相似文献

The roles and functions of 52 school psychologists from Iowa and Tennessee were examined. A multivariate analysis of variance (MANOVA) was used to test differences between reported time spent on prereferral, assessment, intervention, consultation, and curriculum-based assessment. Significant differences were found for the time spent in all areas. A second one-way MANOVA was used to test the differences between the two groups in reported actual time spent and desired time spent. A significant difference was found for consultation. A third MANOVA was utilized to test the differences between the two groups' desired time spent on the five variables. A significant difference was found for curriculum-based assessment. The results suggest that school psychologists in Tennessee and Iowa occupy different roles. School psychologists in Tennessee reported spending the majority of their time on assessment activities, whereas the Iowa sample balances their time between the five functions. The Iowa role exemplifies alternative functions for school psychologists. The Tennessee role is oriented more toward the refer, test, place model.  相似文献

Britain’s exit from the European Exchange Rate Mechanism in 1992 and the Second Iraq War in 2003 are two infamous examples of disastrous policy, but governments blunder all the time – whatever party is in power. Infrastructure projects overrun. The aims and techniques of different departments clash. Scandals erupt among officials and politicians. Controversies stymie attempts at agreement and consensus. But why exactly do these failures happen? Are they more or less widespread than in the private sector? And can studying British governments’ decision-making across the twentieth century improve it in the future? In his May 2018 inaugural lecture, Professor O'Hara recommended a slow, deliberative, transparent, democratic and above all humble and sensitive approach in order to avoid another Black Wednesday or ruinous war – an approach in contrast to the populist tone of much recent debate.  相似文献

The popularity and viewership of Nollywood films have expanded across African and Western cities especially those with considerable Diaspora population. This study seeks to investigate whether watching Nollywood films is likely to lead to cross-cultural transmission of Nigeria’s cultural heritage to audience members in South Africa. Data for the study were collected using observation and surveys with Likert-type scales involving participants from a South African college. Results show that watching Nollywood films was significant in increasing participants’ knowledge and appreciation of Nigerian culture. Observed patterns indicate that a small portion of participants could mimic or reproduce some common Nigerian expressions and exclamations while a negligible percentage of participants could actually speak a smattering of Igbo, one of Nigeria’s three major languages.  相似文献

This article examines the development of hacking and cybersecurity software packages as commodities, based on an international political economy of vendors and clients operating in the interstices of international law. Offensive hacking and defensive cybersecurity tools offer new means for surveillance of critics, journalists, and human rights workers, especially in corrupt or authoritarian political systems. The article provides a case study of the Hacking Team, an international “cybersecurity” firm offering spyware and surveillance systems to government security agencies, which was itself hacked and “doxed” in 2015. The leak of documents contributes new knowledge of an international political economy for software products, which exploits the digital rights of targets and which could further undermine general Internet security.  相似文献

The forward skating start is a fundamental skill for male and female ice hockey players. However, performance differences by athlete’s sex cannot be fully explained by physiological variables; hence, other factors such as skating technique warrant examination. Therefore, the purpose of this study was to evaluate the body movement kinematics of ice hockey skating starts between elite male and female ice hockey participants. Male (n = 9) and female (n = 10) elite ice hockey players performed five forward skating start accelerations. An 18-camera motion capture system placed on the arena ice surface captured full-body kinematics during the first seven skating start steps within 15 meters. Males’ maximum skating speeds were greater than females. Skating technique sex differences were noted: in particular, females presented ~10° lower hip abduction throughout skating stance as well as ~10° greater knee extension at initial ice stance contact, conspicuously followed by a brief cessation in knee extension at the moment of ice contact, not evident in male skaters. Further study is warranted to explain why these skating technique differences exist in relation to factors such as differences in training, equipment, performance level, and anthropometrics.  相似文献

Understanding factors that motivate young athletes to continue participation in sport can help key stakeholders cultivate an environment that fosters long-term participation. This investigation sought to determine the performance and participation factors that influenced continued participation in junior cricket. Administration-level data were collected each annual season across a seven-year period by a community-level junior cricket association in Australia and analysed to identify the performance and participation-based predictors of player retention. All players were males aged <16 years. Players were categorised according to whether they remained in (or departed from) the association at the end of each playing season. A multivariate logistic regression model with a stepwise variable selection was employed to identify significant independent predictors of player retention. The number of innings batted and overs bowled were significant participation-related contributors to junior cricket player retention. Performance factors such as the number of wickets taken and the number of runs scored also significantly influenced player retention. Finally, team age group, the number of previous seasons played and age were also significant factors in player retention. This demonstrates that sufficient opportunity for children to participate in the game and expression of skills competence are key factors for retention in cricket.  相似文献
