This study aimed to explore teachers' learning processes through a hybrid cross-cultural lesson study (LS) because little is known about the learning process through this novel and promising LS approach.

This cross-cultural LS lasted over six months focusing on developing a research lesson (RL) related to linear functions/equations by addressing a commonly concerned student learning difficulty. The data collected were lesson plans, videos of RLs, cross-culture sharing meetings and post-lesson study teacher interviews. A cultural-history activity theory (CHAT) perspective (Engeström, 2001) was used as a theoretical and analytical framework, and contradictions were viewed as driving forces of teachers' learning. The data were analyzed to identify contradictions and consequent teachers' learning by resolving these contradictions.

The results revealed four contradictions occurring during the hybrid cross-cultural LS that are related to the preferred teaching approach, culturally relevant tasks, making sense of the specific topic and enactment of the RL. By addressing these contradictions, the participating teachers perceived their learning in cultural beliefs, pedagogical practice and organization of the lesson.

This study details teachers' collaborative learning processes through hybrid cross-cultural LS and provides implications for effectively conducting cross-cultural LS. However, how the potential learning opportunity revealed from this case could be actualized at a larger scale in different cultures and the actual impact on local practices by adapting effective practices from another culture are important questions to be investigated further.

This study expands teacher learning through cross-cultural LS by focusing on contradictions cross-culturally as driving forces.

Volunteers at child helplines play an important role in providing support for children, so keeping them satisfied during encounters is crucial to continue helping children. The purpose of this study is to understand how children’s perceptions of instrumental and emotional support (partner effects) influence volunteer encounter satisfaction, and whether this effect is moderated by a volunteer’s previous encounter experience and levels of interpersonal and service-offering adaptiveness.

The sample consisted of 377 dyads of 116 volunteers and 377 children from online service encounters at a child helpline. Questionnaires were used to measure satisfaction, support and volunteer adaptiveness. A multilevel model was estimated to test the hypothesized moderation effects.

This study revealed that the instrumental support partner effect positively influenced volunteer encounter satisfaction. This relationship was stronger when the previous encounter was less satisfying or for volunteers with higher interpersonal, but not higher service-offering, adaptiveness. Negative effects on the relationship between the emotional support partner effect and volunteer encounter satisfaction were found after a less satisfying previous encounter or for volunteers with higher interpersonal adaptiveness.

This study contributes to the services and volunteerism literature by providing a unique perspective on the interpersonal influence between volunteers and children during service encounters. In the context of child helplines, this paper illustrates how volunteer encounter satisfaction is a function of the intricate interplay between children’s perceptions of the service encounter and volunteers’ perceptions of previous experiences and their adaptiveness.

Drawing on paradox theory, this study explores how ambidextrous sustainability relates to organisational performance in hybrid organisations represented by Swedish municipal housing corporations, and how this relationship is contingent on the organisational structure of these organisations.

The study relies on the data collected from Swedish municipal housing corporations. These data sources consist of a survey sent to the management team members in Swedish municipal housing corporations, financial and non-financial archival data on these corporations, interviews with the management team and board members, and observations of meetings involving the management team and board of directors at a Swedish municipal housing corporation. Quantitative data of the study were analysed using descriptive statistics, correlation analysis and linear multiple regression analysis. Qualitative data were analysed employing deductive thematic analysis and were used to illustrate and discuss the results of the quantitative analysis.

The quantitative findings show that ambidextrous sustainability, i.e. the alignment between an explorative orientation and an exploitative orientation towards sustainability, has a weakly positive relationship with financial performance and a positive relationship with social performance in hybrid organisations represented by Swedish municipal housing corporations. The study further shows that a high level of the structural element “connectedness” weakened the relationship between the ambidextrous sustainability and financial performance of the organisation in the study. In contrast, a lower level of connectedness reinforced and strengthened this relationship. Our qualitative material illustrates how the quantitative findings could be explained by the interaction between the board of directors and the management team of these hybrid organisations.

The study shows how ambidextrous sustainability, employed for conceptualisation of the sustainability strategy in hybrid organisations, represented by Swedish municipal housing corporations, can impact on facets of performance (i.e. financial, social and environmental) differently. The study further highlights the importance of organisational structures in these relationships in a hybrid context.

This paper examines the theoretical issues and research themes of business and management impact. Our empirical setting is the UK Research Excellence Framework 2014 (REF 2014) and the focus is on the nature of research impact. Stakeholders, including Governments, now expect academic outputs to translate to real world benefits beyond the narrow bibliometric type metrics.

Despite decades of academic literature devoted to business and management research impact, current theories cannot explain the apparent disconnect between academic, economic and societal practice. Adopting a UK Business and Management perspective to frame our investigation, we consider the highly contested rhetorical question – What are the current themes and impacts of Business and Management research?

We propose a definition for research impact and consider its measurement. Then, using the 410 Impact Case Studies submitted to REF 2014 #x2013; Unit of Assessment 19, business and management, we examine how high impact unfolds. The implications for business and management research impact from the perspectives of economic, knowledge and responsibility impacts are considered.

This paper introduces a new heuristic algorithm that aims to solve the military route vulnerability problem, which involves assessing the vulnerability of military cargo flowing over roads and railways subject to enemy interdiction.

Graph theory, a heuristic and a binary integer program are used in this paper.

This work allows transportation analysts at the United States Transportation Command to identify a relatively small number of roads or railways that, if interdicted by an enemy, could disrupt the flow of military cargo within any theater of operation.

This research does not capture aspects of time, such as the reality that cargo requirements and enemy threats may fluctuate each day of the contingency.

This work provides military logistics planners and decision-makers with a vulnerability assessment of theater distribution routes, including insights into which specific roads and railways may require protection to ensure the successful delivery of cargo from ports of debarkation to final destinations.

This work merges network connectivity and flow characteristics with enemy threat assessments to identify militarily-useful roads and railways most vulnerable to enemy interdictions. A geographic combatant command recently used this specific research approach to support their request for rapid rail repair capability.
