Detection of biomass change in a Norwegian mountain forest area using small footprint airborne laser scanner data

Different approaches for estimation of change in biomass between two points in time by means of airborne laser scanner data were tested. Both field and laser data were collected at two occasions on 52 sample plots in a mountain forest in southeastern Norway. In the first approach, biomass change was estimated as the difference between predicted biomass for the two measurement occasions. Joint models for the biomass at both occasions were fitted using different height and density variables from laser data as explanatory variables. The second approach modelled the observed change directly using the change in different variables extracted from the laser data as explanatory variables. In the third approach we modelled the relative change in biomass. The explanatory variables were also expressed as relative change between measurement occasions. In all approaches we allowed spline terms to be entered. We also investigated the aptness of models for which the residual variance was modeled by allowing it to be proportional to the area of the plot on which biomass was assessed. All alternative models were initially assessed by AIC. All models were also evaluated by estimating biomass change on the model development data. This evaluation indicated that the two direct approaches (approach 2 and 3) were better than relying on modeling biomass at both occasions and taking change as the difference between biomass estimates. Approach 2 seemed to be slightly better than approach 3 based on assessments of bias in the evaluation.     

The client as learner and the clinician as teacher: Working with an educational lens

This article highlights the social worker's role as educator and how that role relates to clinical practice. The educational component of practice is not grounded in a substantial theoretical, research, or practice literature, and yet teaching is a nascent role for most clinicians. For the most part, the educational aspects of clinical practice have languished, at least from a theoretical perspective, in the shadow of therapy. In this paper we advocate for developing and articulating the clinician/teacher role in order to support effective use of the learning relationship as a dynamic and necessary means for assisting clients in managing life transitions, developmental challenges, and adversity. We propose the use of an educational lens derived from the fields of education, developmental psychology, and cognitive science, to provide perspective from which the client is viewed as learner, and the client‐work relationship is seen as an educational transaction. We highlight the transformative power of educational transactions that we think are as significant as primary caregiving, and also provide a working definition of education as it is used in clinical teaching‐learning relationships. And finally, we elaborate on the range of purposes education may serve in social work practice.     

Voluntary Associations Within the Local Political Context: How Characteristics of the Organizations and the Local Governments Influence Perceptions of Success

A cornerstone of democracy is the capacity of citizens to influence political decisions either through elections or by making their will known in the periods between elections. The aim of the present study is twofold: (1) to explore what factors inherent of the voluntary associations that determine the perceived success in their attempts to influence policy and (2) to investigate what role the composition of the local government have on the perceived success. This study is based on a survey conducted among 404 local voluntary associations in four different municipalities in Sweden. The results show that the frequency contacts influence perceived success positively, while the level of civic engagement of the voluntary associations affected the perceived success negatively. Having a heterogeneous local government also contributed positively to the perceived success to influence policy.

The Use of Adventure Therapy Techniques by Clinical Social Workers: Implications for Practice and Training

Adventure therapy, an experiential intervention that combines outdoor, adventure based activities and group process, is used in direct practice by clinical social workers; however, it is unclear to what extent clinical social workers are actually utilizing these techniques. This research project surveyed a random sample of clinical social workers and examined in greater depth how they are utilizing adventure therapy programming with different clients in various treatment settings, as well as what type of education and training they received for engaging in these practices. A random sample of 646 clinical social workers in NASW responded to the survey, and more than 1/3 of this sample (35.1 %) reported the use of adventure based activities for therapeutic purposes in their social work practice. However, few of the social workers reported formal education or training in the use of adventure therapy, highlighting the need for more attention in both educational and clinical settings to proper instruction around this growing intervention.     

EAT,DWELL, ORIENT

Through a comparative analysis of Julie and Julia and Ginger and Ganesh, this paper examines a pair of culinary texts, similarly organized, that turn to digital media in order to build a narrative about a year-long experiment with food. Through this juxtaposition of two very similar texts, the essay sets in motion a debate about how Asian Americanist critique can open an important window into understanding this sub-genre of Internet-based writing. Though my analysis remains critical of the latent racial implications of each text, I am not denigrating the value of either text or dismissing the potential that either text has to articulate female subjectivity through the lens of the culinary. Rather, my interest in these particular texts derives from wanting to make sense of how texts by avowed feminists who make use of the Internet in order to construct a form of gendered solidarity that ostensibly crosses lines of age, race and class, might also produce familiar Orientalist orthodoxies that continue to marginalize communities of colour, particularly women of colour, in ways that mark a deep anxiety about the position of the middle-class white feminist in the contemporary racial moment.     

Fatigue effects of noise on aeroplane mechanics

Abstract

Subjective fatigue and reaction time performance were measured in a group of 24 aeroplane mechanics, during 1 week of high noise exposure and 1 week of low noise exposure. Subjective ratings were collected before and after each work day. On the last day of each week subjects also completed a reaction time task before and after work. The mechanics felt more sleepy and less energetic during the high noise week. This effect was most evident towards the end of the day and there was a build-up of the effect during the week. Reaction times were prolonged during the high noise week. Possible confounding factors are discussed and found to be less likely explanations of the effects.     

Mutuality in leader–subordinate empowerment expectation: Its impact on role ambiguity and intrinsic motivation

Drawing on leader role set theory, we examine the relationship between the congruence of leaders' and subordinates' empowerment expectations and subordinates' experiences of role ambiguity and intrinsic motivation. Based on cross-level polynomial regression analysis using 168 subordinates and 33 leaders, the results indicated that the relationship between congruence and role ambiguity and intrinsic motivation vary depending on whether leaders misevaluate subordinate empowerment expectations, as well as whether the expectations match. Specifically, subordinates had low role ambiguity and low intrinsic motivation when leaders' and subordinates' empowerment expectations matched at low levels and when leaders underestimated subordinates' empowerment expectations. However, subordinates had low role ambiguity and high intrinsic motivation when expectations matched at high levels. Furthermore, role ambiguity was high and intrinsic motivation was low when the leaders overestimated subordinates' empowerment expectations. Theoretical and practical implications are discussed.     

Supporting the Participation of Disabled Children and Young People in Decision‐making

Increasing children's and young people's participation in decisions, about their own care and about service development, is a policy priority. Although in general participation is increasing, disabled children are less likely to be involved than non‐disabled children and it is unclear to what extent children with complex needs or communication impairments are being included in participation activities. This article presents research exploring factors to support good practice in participation and discusses policy and practice implications.
