Microbial control of diamondback moth,Plutella xylostella L. (Lepidoptera: Yponomeutidae) using bacteria (Xenorhabdus nematophila) and its metabolites from the entomopathogenic nematode Steinernema carpocapsae

Cells and cell-free solutions of the culture filtrate of the bacterial symbiont, Xenorhabdus nematophila taken from the entomopathogenic nematode Steinernema carpocapsae in aqueous broth suspensions were lethal to larvae of the diamondback moth Plutella xylostella. Their application on leaves of Chinese cabbage indicated that the cells can penetrate into the insects in the absence of the nematode vector. Cell-free solutions containing metabolites were also proved as effective as bacterial cells suspension. The application of aqueous suspensions of cells of X. nematophila or solutions containing its toxic metabolites to the leaves represents a possible new strategy for controlling insect pests on foliage.     

Building strong foundations for educational achievement: Language assessments in early childhood education for deaf and hard of hearing children

It is widely accepted that assessment plays a role in monitoring the development of young children with special needs in early intervention/early childhood settings. The process of assessing young children's language skills often looks for delays within a solid language foundation. However, many children who are deaf or hard of hearing (DHH) may not have a solid language foundation to assess, leading to inaccurate assessment. When we reframe how we assess language skills in children who are DHH, we ensure the assessment provides a comprehensive picture of the child's language development. It is important to modify language assessment tools where necessary while ensuring the assessment stays reliable and valid. It is critical to use multiple assessment tools to monitor the child's progress, including standardized assessments and assessment tools normed for DHH populations. Finally, it is crucial to monitor the child's skills in each language that they are using, regardless of which language is used most often. We explain why each of these factors needs to be considered in the assessment of young children who are DHH, will discuss the challenges of assessing this population, and will provide solutions to some of the challenges of assessing language skills in of young children who are DHH.     

Transforming University Practice Through ICT – Integrated Perspectives on Organizational,Technological, and Pedagogical Change

The article focuses on the use of information and communication technology (ICT) for strengthening and transforming university practice in line with the social and technological conditions of the new ideas for interactive universities. The purpose is to use ICT as a change-agent in order to establish new practices – new pedagogical methods, new methods for collaboration and new forms of interplay between physical and virtual learning environments. The article is based on an ongoing case in which both the authors have been engaged: the IT Innovation project (ITI) and E-learning Lab North Jutland (ELL) at Aalborg University in Denmark. The article presents the different initiatives and strategies for innovation of the university and subsequently discusses the work in the perspective of organizational learning and planning theory.     

Disciplinary exclusion: wicked problems in wicked settings

This paper uses Rittel and Webber’s categorisation of wicked problems in order to interrupt discourses around school behaviour. Each of the 10 characteristics suggested by Rittel and Webber are examined using the English education system as a vehicle by which to consider and interrogate their complexity. This endeavour is crucial as although the characteristics of wicked problems naturally overlap, the cannot, and should not, be conflated if we wish to understand how different facets of a wicked problem shed light, and create shadows, that impact on all members of a school community. That school communities can be wicked settings adds nuance to the complexity of the problems that we face when educating students whose behaviours challenge the norms of their educational environment.     

Employee mistreatment and muted voices in the culturally diverse workplace

This study examines mistreatment through the perspectives of employees with different cultural backgrounds and positions in order to understand the ways in which some voices are muted and others are privileged. Mistreatment is interactional, distributive, procedural, or systemic abuse of employees taking place at both interpersonal and institutional levels on the basis of cultural diversity. Narrative analysis of semi-structured interviews with employees of a large research and development organization revealed three types of muted narratives used to respond to mistreatment (muted-but-engaged, angrily disengaged, and resigned) as well as one type of privileged response. The narratives provided evidence of two processes by which voices became muted: repeated silencing over time and silencing through ambiguity of policies.     

LEARNERS’ DEMANDS AND EXPECTATIONS FOR SPACE IN A UNIVERSITY LIBRARY: OUTCOMES FROM A SURVEY AT LOUGHBOROUGH UNIVERSITY1

In this era of e-learning, open-learning and distance learning in the electronic environment, it is interesting to note that library physical space is being given much consideration and thought in higher education institutions. If space is to be provided in an appropriate and welcoming manner, then it is imperative to develop a better understanding of learners’ expectations and needs. In order to provide this intelligence, a major user survey was undertaken at Loughborough University Library in March 2006 of learners’ perceptions of library space. Different kinds of space are provided in the Loughborough University Library, including large group study areas, group study rooms, individual carrels, silence subject floors and personal computer suites. Aspects explored in the survey were how often different library spaces were used as well as the important factors identified when choosing specific space. A further focus was to identify the reasons why library space was used (as well as not used). Further examinations took place of learners’ perceptions of the different space categories. This paper presents the outcomes of the survey (which benefited from over 400 responses). The survey has provided invaluable insight into such issues as noisy versus quiet learning, nature of personal computer access in libraries, importance levels of different factors (such as physical environment and access to library staff) and the role of print (books and journals) in library space. The paper concludes by describing how the survey results have influenced Loughborough University Library future space use. The wider implications for the sector will also be described.     

Patterns of Nonverbal Adaptation in Supportive Interactions

This study seeks initial evidence for the patterns of nonverbal adaptation predictive of emotional improvement after a troubles talk conversation. A total of 128 dyads composed of two unacquainted individuals engaged in a 5-minute conversation about a stressful event, and the nonverbal behaviors of both the supportive listener and discloser were coded for immediacy. We detected a general pattern of matching between interlocutors, which was positively associated with disclosers’ reported emotional improvement above and beyond listener immediacy. Importantly, we found primary support for a discloser-matching model whereby emotional improvement is a function of disclosers matching highly immediate listeners but no support for a listener-matching model whereby emotional improvement is a function of listeners matching disclosers to signal empathy.     

Centralising space: the physical education and physical activity experiences of South Asian,Muslim girls

This paper explores the physical education (PE) and physical activity experiences of a group of South Asian, Muslim girls, a group typically marginalised in PE and physical activity research. The study responds to ongoing calls for research to explore across different spaces in young people's lives. Specifically, I draw on a ‘middle-ground’ approach, using Hill Collins' matrix of domination and the notion of intersectionality. These concepts offer the possibility to explore the kinds of settings (physical, social and cultural) in which girls undertake PE and physical activity, how these spaces influence experience and how the girls navigate these spaces. The study is based in a large, urban, co-educational, secondary school in Yorkshire, England (95% of the students are from minority ethnic communities, 91% are Muslim and 63% live in the top 10% most deprived neighbourhoods in the country). Data generation involved three phases: observations, creating research artefacts in focus groups and in-depth interviews. The findings reveal the diverse ways the girls are physically active. They also demonstrate a complexity to their involvement which is contingent upon space, discourses and people. For example, discourses of competition, ability and peers are more significant within PE; whilst family, religion and culture feature beyond this context. The paper concludes by acknowledging the girls' heterogeneity and agency in the ways they strategically navigate spaces in their quest to be physically active on their terms.
