Authors: Ribeiro Ana Paula Lima , Carneiro João de Deus Souza , De Melo Ramos Thaís , Patterson Laura , Pinto Sandra Maria
Published: June 2018

Purpose

The buying process is affected by many aspects, in which consumer’s age is certainly an important feature to be considered. The purpose of this paper is to evaluate the influence of packaging and labeling of Requeijão cheese on the purchasing behavior of different age groups of consumers in order to obtain marketing information that aid in increasing sales of Requeijão cheese.

Design/methodology/approach

Three focus groups were created, each one composed of ten participants. The first group was aged 18-30 years old, the second group included people aged 31-50, and the third group participants were aged between 51 and 70 years old. Requeijão cheese labeling and packaging was presented to all groups to facilitate a discussion. A moderator asked participants in the three groups about the factors on the packaging and labeling of Requeijão cheese that influence their desire to purchase. Seven final themes were analyzed by thematic analysis: packaging, color and images on label, information, lid, price and brand.

Findings

The factors of greatest importance that influenced purchasing for the first and second group were glass packaging and color labels. Groups 2 and 3 preferred a packaging size of 250 g, an aluminum cap protected with a plastic cap, information, and affordable prices. Group 1 demonstrated high interest in 220 g packaging, metal lid and brands. Group 3 preferred plastic packaging. All groups were attracted by images on labels related to the product origin. The results from this study may be advantageous for creating marketing strategies to increase sales of Requeijão cheese and similar milk products that are sold in comparable ways.

Practical implications

Concept and attitudes toward packaging and labeling have changed in modern times. The present study demonstrates how consumers of different age groups have divergent opinions about packaging and labeling of Requeijão cheese, factors that have huge influences in the purchasing of this product. The results from this study will aid in creating marketing strategies to increase sales of Requeijão cheese and similar milk products that are sold in similar conditions. The findings will also assist manufactures in creating bonds with costumers once packaging and labeling might be produced in accordance with the preference of each age group of consumers, and consequently makes the visual aspects of packaging more attractive to them.

Originality/value

This study collected information about the most features in packaging and labeling of Requeijão cheese that attract consumers in the food buying process. There are many companies that sell Requeijão cheese. Then, it is necessary to understand the needs of consumers in relation to packaging and labeling of similar products, to make it more competitive in the market and to meet the expectations of consumers in order to create bond with them.

Authors: Siddique Muhammad Hussnain , Qamar Muhammad Usman , Hayat Sumreen , Aslam Bilal , Nadeem Habibullah , Hussain Sabir , Saqalein Muhammad , Saeed Javeria , Muzammil Saima
Published: June 2018

Purpose

The purpose of this paper is to evaluate the prevalence and antibiograms of bacteria isolated from various fresh fruit juices at a local market in Faisalabad.

Design/methodology/approach

Fresh fruit juice samples (n=125) were randomly collected using aseptic technique. Each sample (10 mL) was serially diluted with 90 mL of sterile peptone water, from 1×10−1 to 1×10−5. Each dilution was then used to inoculate nutrient agar by surface spread plating. Aerobic colony counts (ACCs) were determined by colony counting. The isolates were sub-cultured on blood and MacConkey agar. Preliminary identification was achieved on the basis of colony morphology and culture characteristic, and confirmed by API® 20E, 20NE, and API® Staph testing. Antimicrobial susceptibility testing was carried out using the Kirby-Bauer disk diffusion assay, per CLSI 2015 guidelines.

Findings

The mean ACC ranged from 2.0×106 CFU/mL to 4.93×106 CFU/mL, with the highest ACC determined for orange juice. Overall, 153 polymicrobial were identified in 125 samples; 103 of these were Gram-negative rods (GNR) and 28 were Gram-positive cocci (GPC). Escherichia coli (n=38), Klebsiella pneumoniae (n=32) and Pseudomonas aeruginosa (n=24) were the predominant GNR; Staphylococcus aureus (n=28) was the predominant GPC. Antibiogram analysis revealed that all GNR were resistant to ampicillin. However, most E. coli isolates were resistant to ceftazidime (72.4 percent of isolates), and ceftriaxone and cefepime (68.9 percent), while most K. pneumoniae isolates were resistant to cefepime (72 percent) and ceftriaxone (64 percent). All S. aureus isolates were resistant to penicillin, while most (64 percent) were resistant to piperacillin; the most effective drugs against bacteria were vancomycin and imipenem.

Practical implications

The findings suggest that the local government regulatory food and public health authorities should take immediate emergency measures. Appropriate surveillance studies and periodic monitoring of food items should be regularly performed to safeguard public health.

Originality/value

The current study revealed the prevalence of multidrug-resistant bacteria in freshly prepared fruit juices sold by local street vendors.
Crisis, sectoral and geographical factors: financial dynamics of Italian cooperatives
Authors: Fusco Floriana , Migliaccio Guido
Published: June 2018

Purpose

The purpose of this paper is to analyze the financial structure of Italian cooperatives in the period before and during the crisis (2004-2013), in relation to two discriminating factors. At this end, it focuses on two research questions: What financial dynamics the Italian cooperatives have involved before, during and after the 2008 crisis, that is, in the decade 2004/2013? Are there statistically differences between business sectors and geographic area?

Design/methodology/approach

Secondary data on AIDA database have been used. The financial structure is assessed using two ratios: the financial leverage ratio and quick ratio. The final sample consists of 1,446 cooperatives. The trend and exploratory analysis, analysis of variance and Tukey-Kramer post-hoc test have been used.

Findings

The financial structure of cooperatives has not been substantially affected by the crisis in any geographic area and business sector, by virtue of resilience of their business model. Moreover, these two factors produce statistically significant differences in the financial structure of cooperatives.

Research limitations/implications

The study takes into account only the cooperatives that survived the crisis, so, presumably, the strongest. Moreover, another and more ratios should be considered at the end to have a more complete view on the financial dynamics.

Originality/value

The literature on resilience of cooperatives is still not very rich. Moreover, this work analyses and integrates aspects and approaches that are not usually considered together.
Muslim minority women in Western Thrace: any room for transformative learning?
Authors: Panitsides Eugenia , Kiouka Eirini Andromachi
Published: June 2018

Purpose

The purpose of this paper is to gain meaningful insights in the learning background, experiences and potential of Muslim minority women in Western Thrace.

Design/methodology/approach

Qualitative data were obtained through 12 semi-structured interviews, which underwent a three-level qualitative analysis, following the “grounded theory” methodology.

Findings

It was depicted that Muslim minority women in Western Thrace are susceptible to patriarchal gender norms governed by stereotypes that restrict women to reproductive and caring roles and deprive them of the fundamental human right to education. Although the data suggest that learning in adulthood evidently bears some transformative dynamic, the limited adult learning experiences of some interviewees in this study are far from accounting for any substantial transformation at the personal or community level.

Research limitations/implications

Subjectivity, biased responses and a limited sample are among research limitations, impeding the generalization of the results and calling for further investigation.

Originality/value

The originality of the study stems from providing a difficult to reach sample of underprivileged women with the opportunity to express their views and perceptions as regards education and learning, drawing on the identification of specific areas for potential interventions in order to transform their lives and communities.
Collaborative innovation: catalyst for a destination’s event success
Authors: Schofield Peter , Crowther Phil , Jago Leo , Heeley John , Taylor Scott
Published: June 2018

Purpose

This paper aims to contribute to theory concerning collaborative innovation through stakeholder engagement with reference to Glasgow City Marketing Bureau’s (GCMB’s) management strategies, which represent UK best practice in events procurement, leveraging and destination branding.

Design/methodology/approach

The research adopts a case study design to facilitate an in-depth evaluation of the destination marketing organisation’s (DMO’s) critical success factors. Multiple perspectives on GCMB’s collaborative innovation are achieved through semi-structured interviews with senior managers from the bureau, key stakeholders and other DMOs.

Findings

GCMB’s success results from long-term, extensive, collaborative engagement, a unique institutional structure and sustained political and financial support through to transformational leadership, strategic event selection and targeted marketing through “earned” distribution channels.

Research limitations/implications

The study takes a single case study approach and focusses on GCMB’s event-led branding strategy. Given the importance but relative neglect of long-term inter-personal relationships in collaborative innovation, future research should focus on the development of social capital and adopt a longitudinal perspective.

Practical implications

The paper provides insights into the collaborative innovation process with a range of stakeholders, which underpins GCMB’s events strategy and its leveraging of the city brand. In particular, the study highlights the need for entrepreneurial leadership and the development of long-term relationships for effective engagement with stakeholders.

Originality/value

Previous research has focussed on outcomes and neglected pre-requisites and the process of collaborative innovation between destination stakeholders. This study examines this issue from the perspective of a successful DMO and presents a conceptual framework and new engagement dimensions that address this gap in knowledge.
Over- and under-estimation of risks and counteractive adjustment for cold chain operations
Authors: Guo Shin-Ming , Wu Tienhua , Chen Yenming J.
Published: June 2018

Purpose

This study proposes the use of cumulative prospect theory (CPT) to predict over- and under-estimation of risks and the counteractive adjustment in a cold chain context. In particular, the purpose of this paper is to address the importance of the socio-demographic characteristics of an individual in influencing risk attitude and the analysis of measurable risk probability.

Design/methodology/approach

This study uses CPT as the basis to develop a decision analysis model in which the two functions of value editing and probability weighting are nonlinear to adequately determine the flexible risk attitudes of individuals, as well as their prospects with numerous outcomes and different probabilities. An experiment was conducted to obtain empirical predictions, and an efficient Markov Chain Monte Carlo algorithm was applied to overcome the nonlinearity and dimensionality in the process of parameter estimation.

Findings

The respondents overweigh the minor cold chain risks with small probabilities and behave in a risk-averse manner, while underweighting major events with larger ones, thereby leading to risk-seeking behavior. Judgment distortion regarding probability was observed under risk decision with a low probability and a high impact. Moreover, the findings indicate that factors, such as gender, job familiarity and confidentiality significantly influence the risk attitudes and subjective probability weighting of the respondents.

Research limitations/implications

The findings fit the framework of CPT and extend this theory to deal with human risk attitudes and subjective bias in cold chains. In particular, this study enhances the literature by providing an analysis of cold chain risk from both the human decision-making and managerial perspectives. Moreover, this research determined the importance of the socio-demographic characteristics of an individual to explain the variability in risk attitudes and responses.

Practical implications

Managers must consider the issues of flexible risk attitude and subjective judgment when making choices for risk mitigation strategies. Given the focus on counteractive adjustment for over- and under-estimated risk, firms could evaluate cold chain risk more accurately, and thereby enhance their resilience to risky events while reducing the variability of their performance.

Originality/value

The current study is the first to materialize the phenomena of over- and under-estimation of cold chain risks, as well as to emphasize the different characteristics for loss aversion and judgment distortion at the individual level.
Integrated behavioral health care for Karen refugees: a qualitative exploration of active ingredients
Authors: Esala Jennifer J. , Hudak Leora , Eaton Alyce , Vukovich Maria
Published: June 2018

Purpose

The purpose of this paper is to explore the “active ingredients” of integrated behavioral health care (IBHC) from the perspective of Karen refugee participants in an IBHC intervention.

Design/methodology/approach

This paper is based on in-depth, semi-structured interviews with participants (n=40) who have received an IBHC intervention for one year. These qualitative data are supplemented by descriptive quantitative data from those same participants.

Findings

This research suggested that IBHC increased awareness and access to behavioral health services, and that IBHC may be especially amenable to treating complex health conditions. The research also found that IBHC provided a point of regular contact for patients who had limited time with their primary care providers, which helped to enhance access to and engagement with health care.

Practical implications

IBHC has the potential to meet the complex needs of Karen resettled refugees living in an urban setting in the USA.

Originality/value

IBHC is a promising approach to help meet the mental health needs of refugees in the USA. There are, however, gaps in knowledge about the “active ingredients” of IBHC. This paper helps fill these gaps by studying how IBHC works from the perspective of a group of Karen refugees; these are critical perspectives, missing in the literature, which must be heard in order to better address the complex conditions and needs of resettled refugees.

A robotic boring system for intersection holes in aircraft assembly
Authors: Guo Yingjie , Dong HuiYue , Wang Guifeng , Ke Yinglin
Published: June 2018

Purpose

The purpose of this paper is to introduce a robotic boring system for intersection holes in aircraft assembly. The system is designed to improve the boring quality and position accuracy of the intersection holes.

Design/methodology/approach

To improve the boring quality of intersection holes, a robot posture optimization model is established. The target of the model is to maximize the robot stiffness and the variate is location of the robot on the guideway. The model is solved by the iterative IKP algorithm based on the Jacobian matrix. To improve the position accuracy of intersection holes, a robot positioning accuracy compensation method is introduced. In the method, a laser tracker is used to measure the actual position and orientation of the boring bar. Combined with the desired position and orientation, the error can be obtained and compensated.

Findings

In practical case of the robotic boring system, the robot stiffness is effectively improved and the surface roughness of intersection holes achieves a grade of Ra0.8. Besides, the robot end achieves a position accuracy of 0.05 mm and an orientation accuracy of 0.05°.

Practical implications

The robotic boring system has been applied successfully in one of the aircraft assembly projects in northwest China.

Originality/value

The robotic boring system can be applied for machining intersection holes in an aircraft assembly. With the robot posture optimization method and accuracy compensation method, the boring quality and position accuracy of the intersection holes can be guaranteed.
An optimized artificial neural network for human-force estimation: consequences for rehabilitation robotics
Authors: Khoshdel Vahab , Akbarzadeh Alireza
Published: June 2018

Purpose

This paper aims to present an application of design of experiments techniques to determine the optimized parameters of artificial neural networks (ANNs), which are used to estimate human force from Electromyogram (sEMG) signals for rehabilitation robotics. Physiotherapists believe, to make a precise therapeutic exercise, we need to design and perform therapeutic exercise base on patient muscle activity. Therefore, sEMG signals are the best tool for using in therapeutic robots because they are related to the muscle activity. Using sEMG signals as input for therapeutic robots need precise human force estimation from sEMG. Furthermore, the ANN estimator performance is highly dependent on the accuracy of the target date and setting parameters.

Design/methodology/approach

In the previous studies, the force data, which are collected from the force sensors or dynameters, has widely been used as target data in the training phase of learning ANN. However, force sensors or dynameters could measure only contact force. Therefore, the authors consider the contact force, limb’s dynamic and time in target data to increase the accuracy of target data.

Findings

There are plenty of algorithms that are used to obtain optimal ANN settings. However, to the best of our knowledge, they do not use regression analysis to model the effect of each parameter, as well as present the contribution percentage and significance level of the ANN parameters for force estimation.

Originality/value

In this paper, a new model to estimate the force from sEMG signals is presented. In this method, the sum of the limb’s dynamics and the contact force is used as target data in the training phase. To determine the limb’s dynamics, the patient’s body and the rehabilitation robot are modeled in OpenSim. Furthermore, in this paper, sEMG experimental data are collected and the ANN parameters based on an orthogonal array design table are regulated to train the ANN. Taguchi is used to find the optimal parameters settings. Next, analysis of variance technique is used to obtain significance level, as well as contribution percentage of each parameter, to optimize ANN’s modeling in human force estimation. The results indicate that the presented model can precisely estimate human force from sEMG signals.
Force sensing drill jig for robotic assisted drilling
Authors: Bendemra Hamza , Al Khawli Toufik , Anwar Muddasar , Swart Dewald , Stefanini Cesare
Published: June 2018

Purpose

The purpose of this paper is to present a novel force sensing jig for robot-assisted drilling used to drill holes for the fastening of floating nut plates in aircraft assembly.

Design/methodology/approach

The paper describes the drill jig, which consists of a parallel gripper, peg-in-hole pins and a back-plate with a recess where a Polydimethylsiloxane cone is placed on top of a force sensor. As the jig approaches the part, the force sensor registers the applied force until it reaches steady state, which indicates full contact between the jig and the part. The peg-in-hole pins then lock into a pre-existing hole, which provides a mechanical reference, and the support plate provides back support during drilling.

Findings

Positional accuracy and the repeatability of the system were successfully placed within the specification for accuracy and repeatability (0.1 mm tolerance and 0.2 mm tolerance, respectively).

Practical implications

The drill jig can be integrated into existing robot drilling solutions and modified for specific applications. The integration of the force sensor provides data for engineers to monitor and analyze forces during drilling. The design of the force sensing drill jig is particularly suited to industrial prototype robot drilling end-effectors for small and medium manufacturers.

Originality/value

The key novelties of this drilling jig are in the compact assembly, modular design and inclusion of force sensing and back support features.
Trainers’ responses to errors matter in trainees’ learning from errors: evidence from two studies
Authors: Zhao Bin , Seifried Jürgen , Sieweke Jost
Published: June 2018

Purpose

Learning from errors is important for employees, particularly at early stages of their career. The purpose of this paper is to examine the influence of perceived trainer responses to errors on trainee learning from errors in a workplace setting. In Study 1, the authors test a model that examines the associations between perceived trainer responses to errors and trainee learning from errors, which are mediated by affective-motivational adaptivity. In Study 2, the authors further hypothesize that the link between perceived trainer responses and affective-motivational adaptivity is moderated by perceived error climate.

Design/methodology/approach

The authors test the hypotheses using data from 213 Swiss apprentices (Study 1) and 1,012 German apprentices (Study 2) receiving dual vocational training.

Findings

Study 1 suggests that negative trainer reaction impedes trainee learning from errors by impairing trainees’ affective-motivational adaptability. Trainer tolerance of errors and trainer support following errors were not related to trainee learning from errors. Study 2 indicates that perceived error climate is an important boundary condition that affects the relationship between trainer responses and trainee learning from errors.

Originality/value

This study contributes to research on learning from errors in three ways. First, it enriches the understanding regarding the role of trainers in enhancing learning from errors in organizations. Second, it extends research on learning from errors by investigating the interaction effects between perceived trainer responses and error climate. Third, it refines knowledge about the role of positive affect in learning from errors. Findings of this study also offer practical insights to trainers and managers regarding what they should do to encourage trainee learning from errors.
Emotional intelligence and authentic leadership: a meta-analysis
Authors: Miao Chao , Humphrey Ronald H. , Qian Shanshan
Published: June 2018

Purpose

Authentic leadership is a popular leadership construct that stimulates considerable scholarly interest and has received substantial attention from practitioners. Among different individual difference variables, there has been a growing interest in studying the connection between emotional intelligence (EI) and authentic leadership; nevertheless, most of the existing literature on this relation was atheoretical and the results for this relation were mixed. Thus, the purpose of this paper is to clarify the relation between EI and authentic leadership.

Design/methodology/approach

A meta-analysis was conducted to examine the relation between EI and authentic leadership and the moderators that affect this relation.

Findings

The results of the present study indicated that: EI is significantly and positively related to authentic leadership (overall EI:

ρ

ˆ

=
0.49

; ability EI:

ρ
¯

ˆ

=
0.08

; self-report EI:

ρ
¯

ˆ

=
0.52

; mixed EI:

); self-report EI and mixed EI have larger associations with authentic leadership than ability EI has; and the relation between EI and authentic leadership does not differ between male-dominated and female-dominated studies.

Originality/value

The present study couches the relation between EI and authentic leadership in theories and identifies important moderators for this relation which explain the heterogeneity in effect sizes for this relation across studies.
Accounting for environmental costs as an instrument of environmental controlling in the company
Authors: Taygashinova Kusnikamal , Akhmetova Alfiya
Published: June 2018

Purpose

The purpose of this paper is study the peculiarities of environmental controlling in the context of the implementation of the sustainable development strategy and the systematization of methods, functions and tools, as well as consideration of the possibility of applying environmental controlling methods in the organization through the consideration of environmental costs.

Design/methodology/approach

The authors solved the following problems. The authors defined the essence of the concept of “environmental controlling;” conducted an analysis of methods, functions and instruments of environmental controlling; investigated the possibility of accounting for environmental costs as an instrument of environmental controlling; and systematized approaches of using the tool of accounting for environmental costs at enterprises.

Findings

The approaches to accounting for environmental costs differ in the degree of integration into the existing accounting system and in the frequency of accounts handling (one-time or regular). One-time solutions to accounting for environmental costs (e.g. environmental design calculations) are calculations conducted independently of traditional accounting. Their advantage lies in the fact that they can be formed and used without affecting the existing cost accounting system. However, they generate additional costs and generally receive less recognition than integrated solutions. Accounting for environmental costs is an integrated part of the existing and regularly conducted accounting system.

Research limitations/implications

Accounting of environmental costs has broad prospects for use in enterprises as an environmental controlling instrument for the improvement of management efficiency and quality.

Originality/value

Accounting for environmental costs is necessary as an instrument of environmental controlling in order to obtain information on the enterprise interdependencies between costs, revenues, consumption of raw materials and energy as well as environmental protection measures. In addition, the consideration of environmental costs can serve companies as a source for the identification of the potential to reduce the cost of output products.
Organizational change in a scenario of political upheaval and economic crisis: a Brazilian case
Authors: Juliboni Marcela Chacur , Garibaldi de Hilal Adriana Victoria
Published: June 2018

Purpose

This paper aims to enhance the understanding of organizational change (OC) and the main critical factors to change.

Design/methodology/approach

A single case study was conducted in a large company with operations in Brazil by means of 21 in-depth interviews. A qualitative perspective was applied to scrutinize the data collected.

Findings

Main critical factors, such as commitment and trust, represent pieces of a puzzle that, when put together in a constructive way, draw a path to successful implementation of a change initiative. On the one hand, a country crisis poses as an obstacle to build change initiative credibility. On the other hand, an economic downturn may represent a retention mechanism. This study allowed the authors to draw a diagram with four groups of people based on their engagement with the organization change initiatives and on their seniority. In brief, the company is in a vicious circle. It is prisoner of a negative loop that causes a destructive effect in the change process, and it does not allow them to think out of the box and explore creative alternatives to face the company challenges.

Research limitations/implications

The research presents a few limitations regarding the chosen method and, also, country and company scenario where the research took place.

Practical implications

The results have implications for human resources development (HRD) scholars and practitioners in the planning and implementation of OC-related initiatives.

Originality/value

This paper contributes to OC literature and practitioners by showing the importance of credibility in change initiatives to achieve their successful implementation. This study also supports the strong relationship among main critical factors to change. Finally, the company is locked in a negative loop that stifles the successive attempts to successfully implement the change initiatives.
“Peer effects” in capital structure decision of Chinese firms-empirical investigation based on Chinese a-share listed firms
Authors: Zhong Tianli , Zhang Tianyu
Published: June 2018

Purpose

The purpose of this paper is to identify if peer firms’ capital structure decision plays a role in determining focal firms’ capital structure decision, despite the fact that correlated effects can also lead to co-movement of financing behavior among firms from the same industry (i.e. industry-specific capital structure).

Design/methodology/approach

Instead of using relative measurement (of individual outcome variable over industry variable) as in previous work, this paper borrows the linear-in-means model and, after controlling for potential endogeneity problems, directly identifies the existence of peer effects with coefficient estimation. To deal with correlated effects, additional empirical investigations such as test of heterogeneity in direction and scale, social multiplier identification test and instrumental regression test based on another instrumental variable (that is less influenced by correlated effects) are performed.

Findings

Using data from Chinese listed firms, this paper, for the first time, identifies the presence of peer effects in capital structure and debt maturity decision. Further investigations show that first, focal firms react asymmetrically to peer firms’ debt adjustment of different direction and scale. Second, social multiplier, a unique attribute of peer effects, is identified in the leverage choices. Third, the significant correlation of capital structure decision remains even if we use another “correlated effects-immune” instrument. All these results point to the fact that peer effects, rather than correlated effects, play a significant role in determining capital structure.

Practical implications

The empirical results of this paper provide strong evidence that firms, driven by motivations such as either learning or competition, will actively react to peers’ financial decisions. As the bridge between individual firms and the industry, social multiplier can be fully taken advantage of to induce positive spillover of good management practices and prohibit inefficient decisions from spreading.

Originality/value

This paper theoretically and empirically introduces peer effects – a well-acknowledged social concept – into capital structure decision of Chinese listed firms, thus both complementing the traditional capital structure theory and providing an empirical paradigm for peer effects research.
Setting the research agenda for measuring sustainability performance – systematic application of the world café method
Authors: Silva Samanthi , Guenther Edeltraud
Published: June 2018

Purpose

The purpose of this paper is to first present potential areas of research for measuring sustainability performance that emerged in a joint researcher–practitioner workshop at the 19th Environmental and Sustainability Management Accounting Network Europe Conference, organized in cooperation with the World Business Council for Sustainable Development. Second, the methodology applied to gain these insights, the world café approach, is critically reviewed.

Design/methodology/approach

The applied method, a world café approach, facilitates collaborative dialogue and was used in the workshop to uncover underlying research themes. A generalized process flow diagram for a world café is presented, highlighting critical aspects that can guide researchers considering the use of the world café method. The results are structured by means of the 5 W (who, what, where, when, why) and 2 H (how) questions, also known as the elements of circumstance.

Findings

Key topics discussed by conference attendees are identified and an overview of potential areas of research are established concerning “measuring sustainability performance”, with a topical focus on impact measurement and value of sustainability. Furthermore, based on the topics identified by practitioners and researchers, this paper develops a list of questions that can guide future research. Finally, the world café method as a means of generating insights into complex topics such as sustainability performance is evaluated.

Practical implications

The list of research questions identified in this paper can serve as guidance for researchers for selecting relevant, practice-oriented research topics. The value of the world café method as an approach to facilitating the generation of participatory and collaborative insights was confirmed for sustainability management. The generalized process flow diagram can act as a starting point when considering the world café method for facilitating large transdisciplinary groups.

Social implications

The world café is a method for facilitating practitioners and researchers exchange, and thereby presents an opportunity for spanning the research–practice gap. By bringing practitioners and researchers together to identify research areas, future research is more likely to have positive social implications.

Originality/value

The paper presents a recent interpretation of future research gained from a large number of sustainability professionals, including practitioners and researchers, by bringing them together using a world café. The world café is a valuable method for a collaborative set-up with immediate feedback loops, which encourages dialogue, in contrast to surveys or individual interviews, on future developments in the field.
Annual chronotypes functionally link life histories and life cycles in birds
Authors: Karagicheva Julia , Rakhimberdiev Eldar , Saveliev Anatoly , Piersma Theunis
Published: June 2018

Life‐history responses to ecological selection pressures can be described by a slow–fast life‐history axis. Along this axis, fast‐living animals usually invest in high breeding output, whereas slow‐living ones prioritize their own survival.

Birds may solve the trade‐off between reproduction and survival by optimizing their seasonal schedules. Breeding early tends to facilitate reproductive success, whereas breeding late increases the chances to survive. On the basis of this argument, short‐ and long‐lived birds should benefit from initiating spring activities earlier and later, respectively.

The timing of seasonal activities, all else being equal, depends on the architecture of endogenous circannual clocks. Particularly, the length of the circannual period relative to the 365‐day environmental year either facilitates the anticipation of seasonal activities (in case of periods shorter than 365 days) or represents a responsive mode (when periods are longer than 365 days). The two alternatives will be manifested by early or late annual chronotypes, respectively.

We hypothesize that in birds, annual chronotype will correspond with position on the “pace‐of‐life scale.” Species with low survival probability, and thus a poor chance of breeding in a next season, should show early annual chronotypes facilitated by circannual‐clock periods shorter than 365 days. In contrast, species with high survival rates should benefit from relatively long circannual periods.

We predicted that circannual‐period lengths should correlate positively with species‐specific adult annual survival rates. Using published data for 16 wild bird species, we confirmed the predicted correlation. In our analysis, we accounted for the possible metabolic nature of circannual clocks, a correlation between rate of metabolism and survival, and phylogenetic relationships.

On the basis of our finding, we propose that evolutionary responsive circannual clocks help birds cope with temporal variation in the environment in ways that are most appropriate for their life‐history and life‐table attributes.

Personalities influence spatial responses to environmental fluctuations in wild fish
Authors: Villegas‐Ríos David , Réale Denis , Freitas Carla , Moland Even , Olsen Esben M.
Published: June 2018

Although growing evidence supports the idea that animal personality can explain plasticity in response to changes in the social environment, it remains to be tested whether it can explain spatial responses of individuals in the face of natural environmental fluctuations. This is a major challenge in ecology and evolution as spatial dynamics link individual‐ and population‐level processes.

In this study, we investigated the potential of individual personalities to predict differences in fish behaviour in the wild. Specifically, our goal was to answer if individual differences in plasticity of space use to sea surface temperature could be explained by differences in personality along the reactive–proactive axis.

To address this question, we first conducted repeated standard laboratory assays (i.e., open‐field test, novel object test and mirror stimulation test) to assess the personality type of 76 wild‐caught Atlantic cod (Gadus morhua). Next, we released the fish back into the sea and monitored their spatial behaviour over large temporal (16 months) and spatial (a whole fjord) scales, using high‐resolution acoustic tracking.

We demonstrate that (a) cod personality traits are structured into a proactive–reactive syndrome (proactive fish being more bold, exploratory and aggressive), (b) mean depth use of individuals is mainly driven by sea temperature and (c) personality is a significant predictor of home range changes in the wild, where reactive, but not proactive, individuals reduced their home range as sea temperature increased.

These findings expand our understanding of the ecological consequences of animal personality and the mechanisms shaping spatial dynamics of animals in nature.
The Apotheosis of the Rule of Law
Authors: Loughlin Martin
Published: June 2018

In 1885 A.V. Dicey identified the rule of law as a key principle of British constitutional law. Presenting it both as a product of English common law method and an expression of classical liberalism, Dicey's concept lingered on into the twentieth century but mainly as a contentious ideological doctrine or simply as a vague rhetorical slogan. During the last fifty years, however, the concept has been revived, recrafted, relocated and reified. The rule of law has become a universal trope, albeit with a range of contestable meanings. This article traces this development, showing how it has been converted into a phrase of considerable political potency not only domestically but also in the international arena.
Insect declines and agroecosystems: does light pollution matter?

Drastic declines in insect populations, ‘Ecological Armageddon’, have recently gained increased attention in the scientific community, and are commonly considered to be the consequence of large‐scale factors such as land‐use changes, use of pesticides, climate change and habitat fragmentation. Artificial light at night (ALAN), a pervasive global change that strongly impacts insects, remains, however, infrequently recognised as a potential contributor to the observed declines. Here, we provide a summary of recent evidence of impacts of ALAN on insects and discuss how these impacts can drive declines in insect populations in light‐polluted areas. ALAN can increase overall environmental pressure on insect populations, and this is particularly important in agroecosystems where insect communities provide important ecosystem services (such as natural pest control, pollination, conservation of soil structure and fertility and nutrient cycling), and are already under considerable environmental pressure. We discuss how changes in insect populations driven by ALAN and ALAN itself may hinder these services to influence crop production and biodiversity in agricultural landscapes. Understanding the contribution of ALAN and other factors to the decline of insects is an important step towards mitigation and the recovery of the insect fauna in our landscapes. In future studies, the role of increased nocturnal illumination also needs to be examined as a possible causal factor of insect declines in the ongoing ‘Ecological Armageddon’, along with the more commonly examined factors. Given the large scale of agricultural land use and the potential of ALAN to indirectly and directly impact crop production and biodiversity, a better understanding of effects of ALAN in agroecosystems is urgently needed.

The aim of the study was to investigate the location of motor neuron somata of geniohyoid muscle in rat. Nine Sprague‐Dawley rats were used in this study. Operations were performed under general anaesthesia. Nembutal sodium, 40 mg per kg intraperitoneally was used for anaesthesia. 0.02 to 0.05 ml of 30% horseradish peroxidase (Sigma Type VI) solution in normal saline was injected into the exposed right geniohyoid muscle. After 48 hr, the animals were fixed by perfusion through left ventricle of heart, first by 100 ml normal saline and then with 500 ml of 1.25% glutaraldehyde and 1% paraformaldehyde in 0.1 M phosphate buffer, pH 7.4, at room temperature, and finally with 500 ml of 10% sucrose in the same buffer at 4°C. The medulla oblongata and first cervical segment of spinal cord were removed, kept in 10% sucrose in above phosphate buffer at 4°C for 24 hr. Thereafter, their serial transverse sections were cut in a cryostat at a thickness of 60 μm. The sections were treated according to tetramethyl benzidine (TMB)‐horseradish peroxidase (HRP) method. HRP‐labelled neuron somata were observed at the following sites: (a) In ventral part of right main hypoglossal nucleus in upper two‐thirds of the closed part of medulla oblongata. (b) In ventrolateral subnucleus of hypoglossal nucleus in lower third of closed part of medulla oblongata. (c) At spinomedullary junction, they were located in dorsomedial part of right ventral grey column; a few were also seen here scattered on right side of central canal and among corticospinal fibres.
Ovulation induction in polycystic ovary syndrome

Published: June 2018

The objective of this narrative review was to suggest a rational order of treatment choices in anovulatory women with polycystic ovary syndrome (PCOS), for whom a multitude of treatment options exist. In obese/overweight women with PCOS the importance of weight reduction should be stressed. Inositol, a dietary supplement with a documented effect on ovulation and without adverse effects in the doses recommended, may be suggested. Additional first‐line medical alternatives include insulin sensitizers, selective estrogen receptor modulators, and aromatase inhibitors. Of these, the aromatase inhibitor letrozole and the combination of clomiphene citrate and metformin have the highest rates of ovulation and live birth. Second‐line treatments are ovarian electrocautery and low‐dose follicle‐stimulating hormone stimulation. Controlled ovarian stimulation with in vitro fertilization, should be considered the last option as it carries a significant risk of ovarian hyperstimulation syndrome in patients with PCOS.
