Assessing oral presentation performance
Authors: Van Ginkel Stan , Laurentzen Ramona , Mulder Martin , Mononen Asko , Kyttä Janika , Kortelainen Mika J. 
Published: May 2017

Purpose
The purpose of this paper is to design a rubric instrument for assessing oral presentation performance in higher education and to test its validity with an expert group.

Design/methodology/approach
This study, using mixed methods, focusses on: designing a rubric by identifying assessment instruments in previous presentation research and implementing essential design characteristics in a preliminary developed rubric; and testing the validity of the constructed instrument with an expert group of higher educational professionals (n=38).

Findings
The result of this study is a validated rubric instrument consisting of 11 presentation criteria, their related levels in performance, and a five-point scoring scale. These adopted criteria correspond to the widely accepted main criteria for presentations, in both literature and educational practice, regarding aspects as content of the presentation, structure of the presentation, interaction with the audience and presentation delivery.

Practical implications
Implications for the use of the rubric instrument in educational practice refer to the extent to which the identified criteria should be adapted to the requirements of presenting in a certain domain and whether the amount and complexity of the information in the rubric, as criteria, levels and scales, can be used in an adequate manner within formative assessment processes.

Originality/value
This instrument offers the opportunity to formatively assess students’ oral presentation performance, since rubrics explicate criteria and expectations. Furthermore, such an instrument also facilitates feedback and self-assessment processes. Finally, the rubric, resulting from this study, could be used in future quasi-experimental studies to measure students’ development in presentation performance in a pre-and post-test situation.
Exercise and work-family conflict: a field experiment
Authors: Clayton Russell W. , Thomas Christopher H. , Schaffer Bryan S. , Stratton Micheal , Garrison Ellen , Mathews Leah Greden 
Published: May 2017

Purpose
Recent research along with anecdotal evidence suggests that exercise may play a role in mitigating perceptions of work-family conflict (WFC). However, the temporal effects related to this relationship have been ignored. The purpose of this paper is to address this issue by testing for the effects of acute and long-term exercise on the work-family interface.

Design/methodology/approach
Employed females (N=46) were randomly assigned to a treatment (exercise) or control group (no exercise) and data were gathered at three points in time, over four weeks. Linear Mixed Model processes were conducted.

Findings
The authors found that there is a statistically significant long-term exercise effect on strain-based work interference with family and family interference with work.

Research limitations/implications
The sample was restricted to sedentary females, was predominantly white/Caucasian, and held white-collar jobs, limiting the generalizability of the findings.

Practical implications
Results from the current study suggest that exercise assists individuals in managing the work-family interface. While this is not a broad-sweeping call for all employers to offer on-site exercise facilities, the authors suggest that employers consider offering accommodations to individuals seeking to utilize exercise as a way to reduce WFC and general stress.

Originality/value
This is the first empirical study that examines the temporal impact of exercise on the work-family interface.
A useful shift in our perspective: integrating social movement framing into social marketing
Authors: Daellenbach Kate , Parkinson Joy 
Published: May 2017

Purpose
The elaboration of framing in social movement theory offers a different perspective than is typically taken in social marketing. This paper explores how social marketing may benefit from this alternate lens.

Design/methodology/approach
The construction, features and processes associated with collective action frames in social movements are examined and explored via two social causes: obesity and disaster preparation.

Findings
A social movement perspective on framing highlights the need to better understand variations in how groups may perceive a problem and its solutions. It suggests a range of considerations and options in constructing and participating in the development of collective action frames, which are suggested to benefit social marketing initiatives and, thus, society.

Research limitations/implications
Further research in societal well-being and the meso-level of social change should consider adopting a social movement framing perspective. A list of questions is provided to guide future research.

Practical implications
Mobilising a group into action is often a necessary and effective step in realising social change. The questions raised in social movement framing will equip practitioners and researchers with greater understanding of the issue, the context and potential solutions, ultimately to encourage positive social movements and social benefit.

Originality/value
While calls have been made for broader perspectives in social marketing, little attention has been given to social movements. This paper offers a way forward with respect to framing.
Practice-theoretical possibilities for social marketing: two fields learning from each other
Authors: Spotswood Fiona , Chatterton Tim , Morey Yvette , Spear Sara 
Published: May 2017

PurposeThis paper aims to introduce key concepts from practice theory (PT) to the social change agenda and draw on the unique contributions of the social marketing field. PT has underpinned a growing stream of research in pro-environmental studies seeking to reduce impacts of particular behaviours, but it remains theoretical. By drawing on social marketing’s applied roots, this paper introduces a practice-theoretical intervention planning process (P-TIPP) which frames the unique contribution of social marketing in behaviour change and foregrounds practice- not individual-level change.Design/methodology/approachThe P-TIPP draws on the total process planning model, introducing the concept of “practice as entity” and “practice as performance” to frame intervention planning tasks. The process locates the contribution of social marketing within a transdisciplinary framework which emphasises transforming collective conventions.FindingsThis is a conceptual paper, but the possibility for PT to make a significant contribution to the world of social marketing is outlined.Research limitations/implicationsP-TIPP is untested. Also, practices can be difficult to identify and somewhat abstract. Finally, it can be challenging to introduce the approach to policy, funding and practitioner procedures.Practical implicationsThe implications of P-TIPP are that social change interventions are devised, underpinned and planned using insights from PT, such as the way behavioural patterns fit into broader understandings of practice. The subsequent social change agenda will be inherently transdisciplinary, sustainable and reduce focus on individual power to change.Originality/valueThis paper is a first attempt at exploring what PT, and social marketing can learn from each other for the future effectiveness of social change activity.
Topology optimization-based design method of dual-band antennas
Authors: Wang Qi , Gao Renjing , Liu Shutian , Liu Chuan 
Published: May 2017

Purpose
Recent development of wireless communication devices dictates that miniaturization, multi-functions and high integration are the important factors for antenna structures. This has resulted in the requirement of antennas with dual or multi-frequency operations. Although the dual-band antennas can be achieved through the experience-based configuration selection with the parameter adjustment, it is still a challenging problem to design an antenna with specific dual-frequency operations effectively. The purpose of the paper is to develop an effective design method to guide the design of antennas with specific dual-frequency operations.

Design/methodology/approach
The topology optimization is carried out through the material distribution approach, where the patch of the antenna is taken as the design domain. The optimization formulation is established with maximizing the minimum antenna efficiency at the target frequencies. The sensitivity of the antenna efficiency with the design variables is derived, and the optimization problem is solved by a gradient-based algorithm.

Findings
Based on the proposed design method, an example of a patch antenna design for specific dual-frequency operations is presented. The performance of the designed antenna is cross-verified by experimentation, where the reflection coefficients (S11) obtained by simulation and experiment show a good agreement. The simulation and the experimentation of the designed antenna show that two operational bands are optimized to occur around the target frequencies, which confirms the effectiveness of the proposed design method.

Originality/value
This paper presents a topology optimization-based design method for patch antennas operating at dual specific frequencies.
A symplectic Runge-Kutta method for the analysis of the tethered satellite system
Authors: Xu Nuan Fang , Deng Zi-Chen , Wang Yan , Zhang Kai 
Published: May 2017

Purpose
The purpose of this paper is to study the dynamic vibrations of the tethered satellite system (TSS).

Design/methodology/approach
The energy principle and the variational approach are used to establish the dynamic equations of the TSS. By introducing new generalized coordinates, the equations are transformed into the Hamiltonian system. Then, the symplectic Runge-Kutta (SRK) method is used to solve the canonical equations.

Findings
The influence of the tether length on the dynamic behavior of the TSS is very important.

Originality/value
The dynamic responses of the TSS are obtained by using the SRK method.
WIL and business graduate skill transfer to workplace
Authors: Sangwan Shweta , Garg Shalini 
Published: May 2017

Purpose
The purpose of this paper is to understand MBA skill transfer, employability and how work-integrated learning (WIL) can help in ensuring the availability of employable managers after the completion of MBA. India faces a major crisis in terms of finding employable workforce despite its huge population. The paper explores the question of employability. It focuses on how WIL can be used to facilitate transfer of skills, which ultimately leads to a more employable workforce.

Design/methodology/approach
Existing research was studied to establish linkages between WIL and skill transfer. The existing skill gaps in MBA education, which lead to unemployable business graduates, were also revealed.

Findings
The literature studied suggests that there is a positive impact of obtaining an MBA degree on the employability of business graduates. However, there is no concrete evidence to show that the impact is big enough to cover the cost and time spent on pursuing the degree. The paper also reveals the various types of WIL modules being followed by some universities to improve skill transfer and to ensure that graduates are work-ready.

Research limitations/implications
Though the question of employability poses a serious threat to the Indian education as well as the industry, little has been done to assess the ways in which the graduates can be made employable. WIL is also being practiced in a very narrow sense and only by institutes of repute. WIL is being practiced in certain countries and the Indian business schools can use these programmes as a guide.

Originality/value
The paper studies the question of employability from the point of view of the Indian economy and educational institutions. It draws from the experiences of other countries in trying to include WIL into the degree programme to facilitate skill transfer.
Visual cues and innovation adoption among bottom of the pyramid consumers
Authors: Hasan Md Rajibul , Lowe Ben , Rahman Mizan 
Published: May 2017

Purpose
This paper aims to explore how visual comprehensibility of a product can affect innovation adoption among the bottom of the pyramid (BOP) consumers in Bangladesh.

Design/methodology/approach
This is an exploratory qualitative study based on interviews with eight managerial respondents involved in the design and marketing of innovative products targeted at BOP consumers in Bangladesh and three respondents who are consumers of these products.

Findings
One key finding from this research, in comparison to innovation adoption research in developed contexts, is the distinct importance that BOP consumers attach to visual cues in learning about and understanding a new product.

Practical implications
This research provides guidance for private and public sector organisations selling products and services to BOP consumers explaining the role of visual cues in generating better product comprehension. It also identifies the role of social relations in facilitating the adoption of new products within this segment.

Social implications
By enhancing the adoption of so-called pro-poor innovations, this research can assist in bringing about positive social change and developmental benefits in this burgeoning segment of the market.

Originality/value
This is one of the first studies to consider innovation adoption of pro-poor innovations in BOP markets and one of the first studies to collect data on the role of visual comprehensibility for consumers in BOP markets.
Brand adoption by BoP retailers
Authors: Sinha Piyush Kumar , Gupta Suraksha , Rawal Saurabh 
Published: May 2017

Purpose
The purpose of this paper is to develop a framework to understand how bottom of the pyramid (BoP) retailers adopt brands who sell to a very different set of customers and are served through long indirect channels.

Design/methodology/approach
In this study, 60 retailers belonging to different villages of Central and North Gujarat were interviewed. The interviews were audio recorded, transcribed and analyzed. A grounded theory-based analysis was carried out.

Findings
The analysis brought out six criteria used by the retailers in selecting brands with demand for the brand as the most dominant factor. Other criteria included brand adoption by other retailers, profitability, influence of wholesaler/distributor and packaging.

Originality/value
Previous studies with regard to brand adoption by retailers have focused on large retailers who are approached directly by the brands. There is a lack of studies on how BoP retailers adopt brands. Most studies have approached the subject from a distribution perspective of reaching these markets.
Management control facing the challenges of overall performance
Authors: Travaillé Denis , Naro Gérald 
Published: May 2017

Purpose
This paper aims to focus on the role of management control function in the strategies of corporate social responsibility adopted by companies. Since the years 1980/1990, multidimensional models appeared that give an integrated or balanced representation of performance. In parallel, facing the challenges of sustainable development (SD) and taking them into account in the management of companies, the concept of overall performance has developed. But, at the same time, research based on neo-institutional sociology suggests on the contrary the existence of a loose coupling between a management control oriented towards the search for legitimacy and the internal practices of management control.

Design/methodology/approach
The study took place between 2010 and 2015. In 2010, the authors conducted a primary exploratory survey of a sample of 40 management controllers. The study was continued in 2015 by a survey of 60 management accountants. The questionnaires were administered electronically. Sorting and cross-sorting, along with tests of independence based on the χ2 test, were carried out.

Findings
The results of the surveys have allowed us to observe the absence of significant links between proactive strategies displayed by companies in SD and the missions and instruments of management control. These latter would focus solely on measurement, monitoring and reporting of an exclusively economic and financial performance.

Research limitations/implications
This is an exploratory study among French controllers. This study could be deepened by an international survey of a larger sample and by case studies with different managers involved in SD steering.

Practical implications
The study highlights the need to involve management controllers in steering SD.

Social implications
While the literature in management control highlights the role of management accountants in the strategic alignment of SD, this study has shown the weakness of this role.

Originality/value
The article shows the weak involvement of management controllers in the implementation of SD, while the latter would want to become more involved in the steering of SD.
Functional traits of tropical trees and lianas explain spatial structure across multiple scales
Authors: Clark Adam Thomas , Detto Matteo , Muller‐Landau Helene C. , Schnitzer Stefan A. , Wright S. Joseph , Condit Richard , Hubbell Stephen P. 
Published: May 2017

AbstractDispersal and density dependence are major determinants of spatial structure, population dynamics and coexistence for tropical forest plants. However, because these two processes can jointly influence spatial structure at similar scales, analysing spatial patterns to separate and quantify them is often difficult.Species functional traits can be useful indicators of dispersal and density dependence. However, few methods exist for linking functional traits to quantitative estimates of these processes that can be compared across multiple species.We analysed static spatial patterns of woody plant populations in the 50 ha Forest Dynamics Plot on Barro Colorado Island, Panama with methods that distinguished scale‐specific differences in species aggregation. We then tested how these differences related to seven functional traits: growth form, dispersal syndrome, tree canopy layer, adult stature, seed mass, wood density and shade tolerance. Next, we fit analytically tractable spatial moment models to the observed spatial structure of species characterized by similar trait values, which allowed us to estimate relationships of functional traits with the spatial scale of dispersal, and the spatial scale and intensity of negative density dependence.Our results confirm that lianas are more aggregated than trees, and exhibit increased aggregation within canopy gaps. For trees, increased seed mass, wood density and shade tolerance were associated with less intense negative density dependence, while higher canopy layers and increased stature were associated with decreased aggregation and better dispersal. Spatial structure for trees was also strongly determined by dispersal syndrome. Averaged across all spatial scales, zoochory was more effective than wind dispersal, which was more effective than explosive dispersal. However, at intermediate scales, zoochory was associated with more aggregation than wind dispersal, potentially because of differences in short‐distance dispersal and the intensity of negative density dependence.Synthesis. We develop new tools for identifying significant associations between functional traits and spatial structure, and for linking these associations to quantitative estimates of dispersal scale and the strength and scale of density dependence. Our results help clarify how these processes influence woody plant species on Barro Colorado, and demonstrate how these tools can be applied to other sites and systems.
Neighbourhood effects determine plant–herbivore interactions below‐ground
Authors: Huang Wei , Zwimpfer Elias , Hervé Maxime R. , Bont Zoe , Erb Matthias 
Published: May 2017

Abstract

Plant neighbours can strongly influence the interactions between herbivores and focal plants, for instance by providing food of different quality (consumptive effects) or by changing the behaviour and metabolism of the herbivore and the focal plant without being consumed (non‐consumptive effects). Determining the species‐specific contributions of consumptive and non‐consumptive effects is important to understand the ecophysiological mechanisms which underlie neighbourhood effects.

We quantified the impact of nine different grassland plant species on the interaction between Taraxacum officinale and the root‐feeding insect Melolontha melolontha. We investigated the contribution of consumptive and non‐consumptive effects to the observed patterns, and evaluated the impact of neighbouring plants on the growth and physiology of T. officinale upon M. melolontha attack.

Melolontha melolontha growth was strongly affected by the presence of different neighbouring species. The three grass species increased larval growth when growing with T. officinale, with Poa pratensis having a synergistic effect in the mixture compared to both monocultures. The forb Centaurea stoebe reduced larval growth when growing with T. officinale or alone. The other five species had no measurable impact on larval performance. Based on these results, P. pratensis and C. stoebe were selected for further experiments.

Diet‐mixing experiments showed that P. pratensis increased M. melolontha growth when offered together with T. officinale, while C. stoebe suppressed it. When feeding was restricted to artificial diet, larval growth was not changed by the presence of P. pratensis or C. stoebe. However, when feeding was restricted to T. officinale, larval growth was increased by both heterospecific neighbours. Biomass and primary metabolism of T. officinale under attack by M. melolontha was also altered by the presence of C. stoebe and P. pratensis. Together, these results show that consumptive and non‐consumptive effects can explain the positive effect of P. pratensis. In contrast, the negative effect of C. stoebe is likely driven exclusively by intoxication.

Synthesis. The performed experiments suggest that different combinations of consumptive and non‐consumptive effects are likely to contribute to the diversity of neighbourhood effects in nature. Furthermore, they show that neighbourhood effects are important factors in below‐ground plant–insect interactions.
Enabling Social Identity Interaction: Bulgarian Migrant Entrepreneurs Building Embeddedness into a Transnational Network
Authors: Stoyanov Stoyan 
Published: May 2017

AbstractBulgarian migrant entrepreneurs (MEs) approaching diaspora networks (i.e. ethnic spaces in host countries) provides a unique context for exploring the processes by which peripheral actors achieve embeddedness. The study considers how in‐group social norms and expectations influence out‐group candidates’ network standing. The integration of the social identity perspective with embeddedness research allows the identification of the sequence of intergroup actions and the circulation of identity signals between groups. Traditionally, the social identity perspective focuses on the act of constructing identity through positively stereotyping in‐groups and negatively stereotyping out‐groups. Nevertheless, an empirical study of 12 cases of Bulgarian MEs indicates that the circulation of identity signals that facilitate inter‐group comparison can result in complementarity and brokerage. The study suggests the existence of a novel strategy (i.e. social circulation), to add to already known social identity strategies (i.e. social mobility, social creativity and social change). In contrast to previous constructs, the new one does not occur at the expense of either in‐groups’ or out‐groups’ identity. Thus, it adopts an integrative logic, currently missing from the social identity perspective.
