BEDLOAD TRANSPORT IN A POOL-RIFFLE SEQUENCE OF A COASTAL ALASKA STREAM1

ABSTRACT: A Helley-Smith pressure differential bedload sampler was used to measure bedload transport at consecutive riffle sections of a riffle-pool-riffle sequence on Bambi Creek, a small (154 ha), second-order stream on Chichagof Island, Alaska, during four storms over a 2-year period. Maximum bedload transport rate measured was 4920 kg/h at a streamflow of 2.35 m³/s corresponding to a storm having a 5-year return interval. Transport of larger sediment (> 8 mm) varied systematically with streamflow at the two sampling locations. At flows up to approximately bankfull, transport of large sediment was greatest at the upstream site; at flows above bankfull, transport of large sediment was greatest at the downstream site. The net import of large sediment to the pool during moderate stormflows and net export of large sediment from the pool during flows above bankfull may be related to a “convergence” or “reversal” of competence between the upstream riffle and subsequent pool at flows approximating bankfull stage. Cross-sections monitored within the study reach indicate that stormflows resulted in net filling of the riffle sections and net scour of the pool; periods of low streamflow resulted in net scour of the riffles and net filling of the pooL     

690V变频器在造纸厂的应用

在大型造纸厂经常会遇到使用200~1 000 k W变频电动机的情况。因为0.38 k V电机生产工艺的原因不可能做到很大功率,而中压(10 k V,6 k V)的变频器因为价格、安全与稳定性的原因也有其缺陷,所以0.69 k V这个电压等级的变频器就有了用武之地。     

“We can keep the fire burning”: building action competence through environmental justice education in Uganda and Germany

The global dimensions of climate change necessitate a response that takes national differences – social, economic, geographic, and cultural – into account. Action-oriented education has a key role to play in advancing citizen engagement in a culture of sustainability. This paper describes research conducted with one such education programme, Youth Leading Environmental Change (YLEC), which operates in six countries and engages university-aged youth in discussion and practice related to global sustainability, systems thinking, and environmental justice. YLEC aims to advance four key competencies; this paper focuses on the goal of action competence, which involves acquiring knowledge, reflecting on experience in the context of one’s values, envisioning alternative futures, and acting individually and collectively to advance those alternatives. The present article examines the impacts of YLEC on environmental action competence in two of the countries involved in this research: Uganda and Germany. In-depth interviews were conducted with participants in both countries to examine the development of action competence during and after the programme. Findings suggest that outcomes differed in each country, reflective of participants’ different lived experiences. YLEC effectively built on the conditions faced in each country to accompany youth to a higher level of awareness and action. These findings have implications for environmental education programmes striving to work with multiple nations and diverse participants.     

Asian Americans and workplace discrimination: The interplay between sex of evaluators and the perception of social skills

In two role‐playing scenarios, we investigate how White male and female evaluators perceive an Asian American versus White job candidate on the dimensions of competence and social skills and how these perceptions affect evaluators' decisions in hiring and promotion. Specifically, Study 1 examines how the perceptions of competence and social skills affect Asian (versus White) college graduates' chance of obtaining a non‐technical (versus technical) position, and Study 2 tests how these perceptions affect Asians' probability of promotion relative to Whites'. Our findings suggest that female evaluators were less likely to select Asian than White candidates into positions involving social skills and were less likely to promote Asian than White candidates into these types of positions. Furthermore, female evaluators' perception that Asians were less socially skilled than Whites mediated both of these decisions. This paper contributes to the understanding of workplace discrimination of Asian Americans. Copyright © 2012 John Wiley & Sons, Ltd.     

Using self‐determination theory to understand the relationship between calling enactment and daily well‐being

This paper contributes to the calling literature by using self‐determination theory—a theory that makes distinctions between different types of motivation—in order to gain a better understanding of how enacting a calling may relate both positively and negatively to well‐being. We use a daily diary method novel to the calling field and a sample with a distinctive calling, Church of England clergy. We expect daily calling enactment to relate positively to daily well‐being via more autonomous forms of motivation (intrinsic and identified motivation) and negatively via less autonomous forms (introjected motivation). Furthermore, we consider how the relationship between calling enactment and motivation may be moderated by perceived competence. The hypotheses were tested using multi‐level structural equation modeling. There was strong support for calling enactment relating positively to well‐being, and this relationship was fully mediated by intrinsic and identified motivation; the hypothesized negative pathway, from calling enactment, to introjected motivation, to well‐being, was not supported. However, perceived competence was found to moderate some of the relationships between calling and the motivation types, where calling enactment is linked to lower introjected motivation at high levels of competence.

The effect of economic consequences on social judgment and choice: Reward interdependence and the preference for sociability versus competence

Competence and sociability (warmth) are fundamental dimensions of social judgment in organizations. However, these qualities are frequently seen as negatively related, with mixed evidence on which is more important. In three studies (N = 993), we investigated the effects of reward interdependence on the preference for sociability versus competence. We predicted that reward interdependence would elicit a more instrumental, calculative mindset, which in turn, would lead individuals to value competence more. Study 1 surveyed working adults who were in actual work groups and found that those who worked in more (vs. less) reward interdependent environments were more likely to think instrumentally and calculatively when considering potential colleagues. This mindset, in turn, was associated with a greater tendency to value competence over sociability. Studies 2 and 3 used an experimental design and found that when people imagined or anticipated working in a situation in which their economic outcomes depended in part on others, they were more likely to adopt an instrumental focus and choose a “competent jerk” over a “lovable fool.” These results call into question a vast social judgment literature that has made claims about the importance of sociability and related constructs without considering the context, and particularly the reward interdependence, often inherent in organizational contexts.
