Abstract The focus of this paper is an examination of mentorship relationships developed as a result of six students’ participation in a local community science centre sponsored through an NSERC/CRYSTAL project. Each year, a number of students participate in after‐school activities sponsored by the community science centre. Much of this work involves a one‐to‐one approach, with a middle years or high school student working with a professor partner. The professor acts as a mentor to the student, facilitating learning in a manner not always feasible within a school setting with large class sizes. For some students this research may be the basis of a science fair project; for others if is simply a study based on individual interest. Mentored students were interviewed about the nature of that mentorship, with the goal of describing the experience from the students’ perspective. Questions focused on the student's experience of working with a mentor, including how the mentorship relationship was formed, what the importance of the voluntary nature of mentoring was, what the benefits and challenges of working with a mentor were, how the mentorship relationship affected the level of content knowledge the student gained, and what effect the mentoring relationship had on the student's continuing interest in science. The mentorship program offers students the opportunity to work within a developing community of practice. 相似文献

Stereotype formation may be based on the exaggeration of real group differences (category accentuation) or the misperception of group differences that do not exist (illusory correlation). This research sought to account for both phenomena with J. K. Kruschke's (1996, 2001, 2003) attention theory of category learning. According to the model, the features of majority groups are learned earlier than the features of minority groups. In turn, the features that become associated with a minority are those that most distinguish it from the majority. This second process is driven by an attention-shifting mechanism that directs attention toward group-attribute pairings that facilitate differentiation of the two groups and may lead to the formation of stronger minority stereotypes. Five experiments supported this model as a common account for category accentuation and distinctiveness-based illusory correlation. Implications for the natures of stereotype formation, illusory correlation, and impression formation are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Responds to R. E. Erard's comments (see record 2009-13007-011) on the current authors' original article (see record 2008-12151-002) which reviewed a number of studies that identified cultural differences in the use and effect of different types of social support among Asians and Asian Americans and European Americans. Essentially, in his comment, Erard denied the validity of research examining cultural differences. The authors strongly believe that the issues concerning within-culture variation do not nullify the importance of conducting research on culturally based psychological and behavioral patterns.

The paper describes the research of fault activation in terms of the Central Asia area, analyzes the time and spatial regularities
of this process and probable disturbers for metastability of the fault-and-block crust medium in real time as well as the
potential influence of the disturbance sources on the stability of rock masses under mining. 相似文献

The present research surveyed a group of editors and editorial board members of personality and social psychology journals to examine the practice of psychological science in their field. Findings demonstrate that (a) although personality and social researchers tend to use many of the same approaches, methods, and procedures, they nonetheless show average differences in each of these domains, as well as in their overarching theoretical aims and perspectives; (b) these average differences largely conform to social and personality researchers’ stereotypes about each subgroup; (c) despite their methodological and philosophical differences, the 2 subgroups study many of the same research topics; and (d) the structure of social–personality research practices can be characterized as having 2 independent factors, which closely correspond to L. J. Cronbach’s (1957) correlational and experimental “streams of research.” (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Users and providers of recycled water in Queensland, Australia, were canvassed to ascertain concerns about recycled water quality and directions for applied research. Some 79% of respondents had concerns about recycled water quality including microbiological components, such as viruses, parasites and bacteria, salinity related components, aggregate components, such as pH and solids, nutrients, organic components, including pesticides and endocrine disruptors, as well as quality variability. Relative differences in the proportion of concern for some quality characteristics were observed between the areas of different population density with those from the low population areas being more concerned than those from medium or high areas. Some users and providers observed changes in recycled water quality during distribution including nutrients, chlorine, solids, colour and odour. Some 52% of providers and 19% of current users propose to expand their usage and 30% of non-users propose to commence doing so in the next 5 years. Recycled water quality characteristics identified for applied research included microbiological components, organic components, nutrients and salinity. 相似文献

Electromagnetic tracking systems are a common component of many virtual reality installations. Their accuracy, however, suffers
from the distortions of the electromagnetic field used in calculating the tracker sensor’s position. We have developed a tracker
calibration technique based on a neural network that effectively compensates for the errors in both tracked location and orientation.
This case study discusses our implementation of the calibration algorithm and compares the results with traditional calibration
methods. 相似文献
