Based on data collected through a complex survey of science and engineering PhD graduates from a UK research-based university, this paper examines the different types of careers and to what extent different types of competences acquired from doctoral education are regarded as valuable in the different career types. The results show that employment outside the conventional technical occupations is the main destination for the survey respondents. This career type is not only successful at retaining its members, but is also the destination of the other career types. Moreover, different types of competences from doctoral education are regarded as relatively more valuable in different career types: knowledge directly tied to subject areas is regarded as more valuable in academia/public research; both knowledge directly tied to subject areas (but more general type of knowledge rather than specialist knowledge in PhD topics) and the more general and transferable skills are regarded as valuable in technical positions in manufacturing; and the general and transferable skills are regarded as more valuable in employment outside the conventional technical occupations. In absolute terms, general analytical skills and problem solving capability acquired from doctoral education are perceived as valuable in all three career types. 相似文献

In this paper, the problem of stability analysis for neural networks with time-varying delays is considered. By the use of a newly augmented Lyapunov functional and some novel techniques, sufficient conditions to guarantee the asymptotic stability of the concerned networks are established in terms of linear matrix inequalities (LMIs). Three numerical examples are given to show the improved stability region of the proposed works. 相似文献

Blood viscosity has been considered as one of important biophysical parameters for effectively monitoring variations in physiological and pathological conditions of circulatory disorders. Standard previous methods make it difficult to evaluate variations of blood viscosity under cardiopulmonary bypass procedures or hemodialysis. In this study, we proposed a unique microfluidic device for simultaneously measuring viscosity and flow rate of whole blood circulating in a complex fluidic network including a rat, a reservoir, a pinch valve, and a peristaltic pump. To demonstrate the proposed method, a twin-shaped microfluidic device, which is composed of two half-circular chambers, two side channels with multiple indicating channels, and one bridge channel, was carefully designed. Based on the microfluidic device, three sequential flow controls were applied to identify viscosity and flow rate of blood, with label-free and sensorless detection. The half-circular chamber was employed to achieve mechanical membrane compliance for flow stabilization in the microfluidic device. To quantify the effect of flow stabilization on flow fluctuations, a formula of pulsation index (PI) was analytically derived using a discrete fluidic circuit model. Using the PI formula, the time constant contributed by the half-circular chamber is estimated to be 8 s. Furthermore, flow fluctuations resulting from the peristaltic pumps are completely removed, especially under periodic flow conditions within short periods (T < 10 s). For performance demonstrations, the proposed method was applied to evaluate blood viscosity with respect to varying flow rate conditions [(a) known blood flow rate via a syringe pump, (b) unknown blood flow rate via a peristaltic pump]. As a result, the flow rate and viscosity of blood can be simultaneously measured with satisfactory accuracy. In addition, the proposed method was successfully applied to identify the viscosity of rat blood, which circulates in a complex fluidic network. These observations confirm that the proposed method can be used for simultaneous measurement of viscosity and flow rate of whole blood circulating in the complex fluid network, with sensorless and label-free detection. Furthermore, the proposed method will be used in evaluating variations in the viscosity of human blood during cardiopulmonary bypass procedures or hemodialysis. 相似文献

This paper describes an assessment of a web‐based interview simulation designed to teach empathetic helping skills. The system includes an animated character acting as a client and responses designed to recreate a simulated role‐play, a common assessment method used for teaching these skills. The purpose of this study was to determine whether learning gains found in previous evaluations would transfer to students needing similar skill sets but in different areas of study. Findings indicate a positive trend in learning gains across both areas of study (human services and counselling) with no significant differences in skill acquisition. Developers of the system conclude that the system is effective in the general training of empathetic helping skills regardless of the students' area of study. 相似文献

Attention-deficit/hyperactivity disorder (ADHD) and learning disabilities (LD) are the most commonly diagnosed childhood disorders,
and they frequently co-occur with each other. It has been found that students with comorbidity of ADHD and LD experience more
difficulties in school. Even though the research interests in the comorbidity of ADHD and LD are increasing, there are inconsistent
results in research studies and insufficient understanding of the comorbidity of ADHD and LD. This study attempts to grasp
the progress of the studies in the comorbidity of ADHD and LD in Korea and to suggest the future directions for following
research. A total of 90 studies published between 1987 and 2009 are examined. First, we analyze the studies that examined
the learning problems of ADHD and then identify the characteristics of the learning problems in ADHD group. Afterwards, we
investigate the studies that dealt with the attention problems of LD and then discuss the characteristics of the attention
problems in LD group. Third, we identify the differences between ADHD and LD and synthesize the research findings. Finally,
we analyze the studies conducted in conjunction with the comorbidity of ADHD and LD. On lightening the research of the comorbidity
on three aspects, we find the research trend in Korea and provide the implications for future studies on the comorbidity of
ADHD and LD. Furthermore, we suggest that it is important to identify comorbid conditions at the early stage, and it is necessary
to conduct multidisciplinary research and international comparison research. 相似文献

This study employed the uses and gratification approach to investigate how journalists perceive relational satisfaction with the public on Twitter, specifically the associations between journalists’ motivations to use Twitter, their Twitter use, and their relational satisfaction with the public. Through a survey of South Korean journalists, this study revealed that journalists’ motivations for Twitter use are positively related to their job-related activities on Twitter (e.g., posting/sharing their news and interacting with audience), which consequently influences perceived relational satisfaction with the public. The findings provide new insight into an increasingly important part of the public’s engagement and news/information flows in the digital media environment. This study expands upon the literature by analyzing how journalists’ motivations for using Twitter and their job-related activities on Twitter are associated with relational satisfaction with the public. 相似文献

This paper examines the video-based pedagogical practices of Terry (pseudonym), a head coach of a professional junior academy squad. Data were collected through 6 in-depth, semi-structured interviews and 10 field observations of Terry’s video-based coaching in situ. Three embracing categories were generated from the data. These demonstrated that Terry’s video-based coaching was far from apolitical. Rather, Terry strategically used performance analysis technologies to help fulfil various objectives and outcomes that he understood to be expected of him within the club environment. Kelchtermans’ micropolitical perspective, Callero’s work addressing role and Groom et al.’s grounded theory were primarily utilised to make sense of Terry’s perceptions and actions. The findings point to the value of developing contextually grounded understandings of coaches’ uses of video-based performance analysis technology. Doing so could better prepare coaches for this aspect of their coaching practice. 相似文献

AbstractThis paper explores the migration of female basketball players from Taiwan to China. Governance theory is adopted as the framework in this study to analyze the phenomenon of players’ migration and to understand how it was shaped over the years. The empirical work draws on a qualitative approach, which is based on a review of documentary materials and semi-structured interviews; coding and analysis were undertaken with a content analysis approach in order to investigate the decision-making processes and their consequences for the players’ migration. The feature of systematic governance for the development of women’s basketball has been revealed in this study. Stakeholders with personal interests caused the downturn of women’s basketball development in Taiwan, and it eventually led to the players’ migration abroad. Through the lens of governance theory, it has been revealed that a number of factors – namely, political, financial, personal, socio-economic, and cultural – all intertwine with one another dynamically to influence the female players’ decision to move abroad. This finding broadens the scope for the research of Taiwanese athletes’ migration to China, extending the focus from only business or industry to other aspects, thereby highlighting the fact that the subject is more complex than previously understood. 相似文献
