Efforts to professionalize counseling practice have yielded extraordinary benefits to counselors. However, professionalization
has also caused counselors to adopt strict definitions of their education, practices, and ethics. In order to combat the ideological
insularity brought on by professionalization, several marginalized ideas are considered. The implications of these ideas and
ways to overcome ideological insularity are discussed. 相似文献

The high school grade point average (GPA) is often adjusted to account for nominal indicators of course rigor, such as “honors” or “advanced placement.” Adjusted GPAs—also known as weighted GPAs—are frequently used for computing students’ rank in class and in the college admission process. Despite the high stakes attached to GPA, weighting policies vary considerably across states and high schools. Previous methods of estimating weighting parameters have used regression models with college course performance as the dependent variable. We discuss and demonstrate the suitability of the graded response model for estimating GPA weighting parameters and evaluating traditional weighting schemes. In our sample, which was limited to self‐reported performance in high school mathematics courses, we found that commonly used policies award more than twice the bonus points necessary to create parity for standard and advanced courses. 相似文献

In an attempt to produce more news stories, faster and on different platforms, the national Danish Broadcasting Corporation, DR, has introduced a new workflow. This new workflow is based on principles and practices known internally as “the news engine,” and it has brought with it changes in regards to both the news products, the news processes and the individual news producers. This article is based on newsroom observations, interviews with employees and content analyses, and it shows how the practice of journalism at DR News has been altered in several ways after the implementation of the news engine. The changes in DR News have become the inspiration for other television stations, and the study concludes by discussing how this particular workflow affects the profession of journalism. Rather than a proletarianization of the profession, this study points to a polarization where some journalists experience a deskilling and a decrease in autonomy, while others experience an increase in autonomy as part of a process of reskilling and multiskilling. 相似文献

Scholars in diverse fields of inquiry have identified the need to expand individual-based information seeking and behavior models and systems to incorporate social as well as collaborative dimensions. However, the research areas of Social Information Seeking (SIS) and Collaborative Information Seeking (CIS) have been largely disconnected from one another despite a few notable attempts to study them under one umbrella. Researchers in these communities have recently realized the value of bringing SIS and CIS together for two main reasons: often it is impossible to separate social and collaborative dimensions in a project; and by considering these two aspects of information seeking, we may be able to support human information behavior in ways not previously possible. A brief synthesis of work in the domains of SIS and CIS is presented here. Then, an integrated view is presented to consider Social and Collaborative Information Seeking (SCIS) as an intersection and extension of SIS and CIS. Benefits of this approach are discussed and the integrated view is used as the basis to present a research agenda that outlines opportunities and challenges unique to SCIS. 相似文献

Organizational performance is highly influenced by how employees envision the future. To date, many scholars have emphasized the importance of an overarching future vision that unites all stakeholders, while acknowledging the presence of divergent perspectives among members. This variety in perspectives may be further complicated in organizations undergoing great stress and where the leadership has not defined and promoted a future vision to guide the content of the images of its members. Little study has explored the various types of future organizational images that exist or the nature of those images. We explore these concerns via a case study of an airline in the midst of a dramatic fight for survival. The findings both confirm the existence of multiple views for the company's future and delineate their general characteristics through a typology of imagery. We conclude with a language to use to differentiate those images for future research and offer practical implications for managing multiple future organizational images to mobilize energy and enhance performance in a more unified direction. 相似文献

The purpose of this study was to evaluate the role of rotation axes during a tennis serve. A motion capture system was used to evaluate the contribution of the potential axes of rotation (minimum inertia axis, shoulder-centre of mass axis and the shoulder-elbow axis) during the four discrete tennis serve phases (loading, cocking, acceleration and follow through). Ten ranked athletes (International Tennis Number 1–3) repeatedly performed a flat service aiming at a target on the other side of the net. The four serve phases are distinct and thus, each movement phase seems to be organised around specific rotation axes. The results showed that the limbs’ rotational axis does not necessarily coincide with the minimum inertia axis across the cocking phase of the tennis serve. Even though individual serving strategies were exposed, all participants showed an effect due to the cocking phase and changed the rotation axis during the task. Taken together, the results showed that despite inter-individual differences, nine out of 10 participants changed the rotation axis towards the minimum inertia and/or the mass axis in an endeavour to maximise external rotation of the shoulder to optimally prepare for the acceleration phase. 相似文献

In 3 studies we investigated 3- through 6-year-olds' knowledge of thinking and feeling by examining their understanding of how emotions can change when memories of past sad events are cued by objects in the current environment. In Study 1, 48 4-, 5-, and 6-year-olds were presented with 4 illustrated stories in which tocal characters experience minor sad events. Later, each story character encounters a visual cue that is related to one of his or her previous sad experiences. Children were told that the character felt sad and they were asked ot explain why. Study 1 suggested considerable competence as well as substantial development in the years between 4 and 6 in the understandings of the influence of mental activity on emotions. Studies 2 and 3 more systematically explored preschoolers' understanding of cognitive cuing and emotional change with difterent types of situations and cues. Across these 2 studies, 108 3-, 4-, and 5-year-olds listened to illustrated stories that featured story characters who each experienced a sad event and swho were later exposed to a related cue. Children were not only asked to explain why the characters suddenly felt sad, but in some stories, they were also asked to predict and explain how another character, who was never at the past sad event, would feel. Results of studies 2 and 3 showed an initial understanding of cognitive cuing and emotion in some children as young as 3, replicated and extended the evidence for significant developmental changes in that understanding during the preschool years, and revealed that the strenght and consistency of preschoolers' knowledge of cognitive cuing and emotion was affected by whether cues were the sme, or only similar to, parts of the earlier events. 相似文献
