PhD students’ work conditions and study environment in university- and industry-based PhD programmes
During the last 10 years, new models of funding and training PhD students have been established in Denmark in order to integrate industry into the entire PhD education. Several programmes have been conducted where it is possible to co-finance PhD scholarships or to become an employee as an industrial PhD in a company. An important question is what impact these new conditions will have on the PhD students’ training, work conditions and study environment. In this article, the new type of programmes will be presented together with data analysis of PhD students’ work conditions and study environment in various programmes mainly based on a research project from 2006. The results of this study show no significant difference between PhD students in a traditional university PhD programme and PhD students in an industrial programme concerning working environment. However, the study shows significant differences in the intercultural dimension, where foreign PhD students are significantly more satisfied with their study environment compared with Danish PhD students. In general the workload is very high and the environment is stressful for all PhD students. 相似文献

This study utilized early reading assessment data from a randomized trial of 210 urban and rural schools in Texas to examine
contextual effects on risk prediction in first and second grade. The primary objective was to examine the roles of (a) individual
differences, (b) the grade 1 classroom, and (c) the pairing of first and second grade teachers in determining grade 2 outcomes
in word reading and fluency. A second objective was to investigate whether the administration format of the assessment (paper,
paper plus desktop, handheld plus desktop) or the level of teacher support (web mentoring, no mentoring) moderated the prediction.
These moderator variables proved not to be significant. Subsequent analyses found that a combination of student pretest and
mean of pretest classroom was a better predictor than student pretest alone. Additionally, the effect of student scores varied
by teacher-pair. On average, intraclass correlations (ICCs) ranged from 6% to 17%. Differences in ICCs at the classroom level
were much greater than at the school level, and differences in urban schools were twice that of rural schools. 相似文献

This paper presents a novel mega-Hz-level super high frequency zero-voltage soft-switching converter for induction heating power supplies. The prominent advantage of this topology is that it can absorb both inductive and capacitive parasitic components in the converter. The switch devices operate in a zero-voltage soft-switching mode. Consequently, the high voltage and high current spikes caused by parasitic inductors or capacitors oscillation do not occur in this circuit, and the high power loss caused by high frequency switching can be greatly reduced. A large value inductor is adopted between the input capacitor and the switches, thus, this novel converter shares the benefits of both voltage-type and current-type circuits simultaneously, and there are no needs of dead time between two switches. The working principles in different modes are introduced. Results of simulation and experiments operated at around 1 MHz frequency verify the validity of parasitic components absorption and show that this convener is competent for super high frequency applications. 相似文献

This paper studies the social talk of high school students in online discussion forums. On-task talk has generally been assessed as valuable discussion because it contributes directly to productive learning. Off-task conversation, on the other hand, is often regarded as useless and a waste of time. Should this social talk indeed be regarded as an off-task activity? Is social talk such as greeting, excusing, comforting and sharing personal feelings irrelevant to learning? This study analyzes threads and argues that social talk is interwoven with on-task talk. It is interesting to note that a substantial quantity of off-task messages served the latent function of guiding group discussion toward making progress in solving collaborative problems in a subtle and indirect manner. The power of “soft talk” embedded in off-task social conversation is explored and fully discussed. 相似文献

We examined the associations between components of temperament and children’s word and pseudo-word reading skills, in a school-age
sample using a within-family internal-replication design. We estimated the statistical prediction of word and pseudo-word
reading in separate regression equations that included the main effects of, and two-way interaction between, Surgency and
Effortful Control. Children with better Effortful Control scores showed better reading skills. Surgency was unrelated to reading
skills, but moderated the effect of Effortful Control. The positive association between reading skills and Effortful Control
was present only for children who were low in Surgency. Thus, reading achievement in school-age children is optimized by strong
Effortful Control, but these processes may be disrupted for those children who are high in Surgency. 相似文献

This study was designed to identify characteristics of family functioning that relate to suicide potential in an outpatient
adolescent population. Participants included 51 adolescents between the ages of 14 and 18 who were involved in outpatient
counselling. The Family Environment Scale and the Suicide Probability Scale were used to assess adolescents’ perception of
family social climate and degree of suicide risk respectively. Results revealed significant correlations between suicide risk
and family systems characterized by heightened conflict and lower levels of cohesion, independence, and organization. A stepwise
multiple regression analysis suggested that organization (related to clarity and structure in family activities and responsibilities)
was the strongest predictor of suicide risk. Implications for research and practice are considered. 相似文献

Relational transgressions are emotionally difficult for those who directly experience the transgression. Less is known about how transgressions affect those located within the personal network of a relational transgression victim. This study explored how network members engaged in support marshaling in response to another’s transgression experience. Results indicate that some participants marshaled support, citing four reasons for their actions: perceived insufficiency, camaraderie, personal ramifications, and personal values. We explore these reasons for marshaling support and discuss them within the broader context of support marshaling and relational transgressions. 相似文献

The logs of four universities using the OhioLINK journal system were evaluated for a period of fifteen months using deep log analysis methods in order to compare and contrast the information seeking behaviour of their users. Large differences were found, especially between the research and teaching universities. Methodological problems associated with making the comparisons are discussed in some detail especially in terms of defining online sessions. 相似文献
