Towards a pragmatic use of statistics in ecology
Authors: Castilho Leonardo , Prado Paulo Inácio 
Published: July 2018

AbstractAlthough null hypothesis testing (NHT) is the primary method for analyzing data in many natural sciences, it has been increasingly criticized. Recently, a new method based on information theory (IT) has become popular and is held by many to be superior for many reasons, not least because is enables researchers to properly assess the strength of the evidence that data provide for competing hypotheses. Many studies have compared IT and NHT in the context of model selection and stepwise regression, but a systematic comparison of the most simple but realistic uses of statistics by ecologists is still lacking. We used computer simulations to compare how both methods perform in four basic test designs (t-test, ANOVA, correlation tests, and multiple linear regression). Performance was measured by the proportion of simulated samples for which each method provided the correct conclusion (power), the proportion of detected effects with a wrong sign (S-error), and the mean ratio of the estimated effect to the true effect (M-error). We also checked if the p-value from significance tests correlated to a measure of strength of evidence, the Akaike weight. In most cases both methods performed equally well. The concordance is explained by the monotonic relationship between p-values and evidence weights in simple designs, which agree with analytic results. Our results show that researchers can agree on the conclusions drawn from a data set even when they are using different statistical approaches. By focusing on the practical consequences of inferences, such a pragmatic view of statistics can promote insightful dialogue among researchers on how to find a common ground from different pieces of evidence. A less dogmatic view of statistical inference can also help to broaden the debate about the role of statistics in science to the entire path that leads from a research hypothesis to a statistical hypothesis.
Motives for buying local, organic food through English box schemes
Authors: Hashem Shadi , Migliore Giuseppina , Schifani Giorgio , Schimmenti Emanuele , Padel Susanne 
Published: July 2018

Purpose
The purpose of this paper is to explain the growing interest of English consumers in local organic food sold through box schemes, by providing insights into the motives of customers of such schemes and examining the relationship with their awareness about problems of the agro-food system.

Design/methodology/approach
A mixed methods approach combined in-depth interviews with 22 box scheme customers with a quantitative survey of 416 consumers, analysed by means of principal component analysis and an ordered logit model.

Findings
Consumers of small local organic box schemes in England are both altruistically and hedonistically motivated. This includes a strong political motivation to change the current food system, as shown by the strong influence of an anti-globalisation factor and wanting to support small farmers. They perceive local organic food as a more environmentally sustainable alternative to the mainstream food system. The box schemes offer consumers a practical alternative by providing high quality products combined with convenience illustrating the importance of the latter also in local food shopping. This reinforces the possibility to successfully combining the attributes of “local” and “organic”.

Research limitations/implications
The study was conducted in only one country (England) with about 400 consumers of ten organic farmer-led box schemes. It was based on a self-selecting sample of consumers of such schemes, which included a large proportion of females and people with high level of education. Further research is needed to validate the results.

Originality/value
This study is the first academic study investigating the main factors affecting consumers’ choice to purchase local organic food through a number of English box schemes. It identifies that such consumers are ethically and politically motivated and show some differences compared with the general literature on organic food consumption.
Corporate social responsibility in the mining industry: an exploration of host-communities’ perceptions and expectations in a developing-country
Authors: Amos Gideon Jojo 
Published: July 2018

PurposeThe purpose of this paper is to explore how and what drives corporate social responsibility (CSR) in host communities of mining companies in developing countries.Design/methodology/approachTo address this knowledge gap, this paper used Ghana as a test case and conducted 24 in-depth interviews with participants drawn from mining host communities.FindingsThe paper discovered that while CSR is broadly understood and encompasses six thematic categories in the mining host communities, there are emphases on philanthropic and environmental responsibilities. Contrary to the evidence found in other studies, this paper discovered that CSR rhetoric plays a more positive/significant role than so far explored in CSR research, as it incentivizes the host communities to push for the fulfilment of their CSR expectations and/or CSR initiatives proposed by mining companies.Research limitations/implicationsQuantitative studies are needed to strengthen the findings from the present paper.Practical implicationsBecause developing countries share similar socio-economic and geo-political realities, the findings of this paper may be applicable not only for CSR advocates, but also for policy-makers in developing countries.Originality/valueThe paper provides new inputs from a developing country perspective to the current debate about the CSR performance of the extractive industry.
Employees shaping their own jobs: how to enable job crafting?
Authors: Menachery Thomas J. 
Published: July 2018

Purpose
The purpose of this study is to review the latest developments in the area of job crafting and provide guidelines on how to enable job crafting.

Design/methodology/approach
The concept of job crafting is examined through a review, and the author gives his insights on the conditions to be created to enable job crafting.

Findings
In job crafting, individual employees and groups of employees customize their jobs by changing perceptions, tasks, and interactions related to their jobs in ways that would lead to work engagement and job satisfaction. Job crafting behavior is positively linked to engagement, work performance, job satisfaction, and employees’ well-being. Organizations can benefit by enabling job crafting to supplement top-down traditional job design approaches, thereby facilitating continuous improvement of jobs and innovation.

Originality/value
The different ways in which employees shape their jobs are examined, and guidelines on how to enable job crafting are elucidated.

Authors: Alrawadieh Zaid , Dincer Mithat Zeki , Istanbullu Dincer Fusun , Mammadova Parvin 
Published: July 2018

PurposeTravelers’ narratives disseminated online about destination experiences are an important source of information for measuring the performance of tourist destinations and understanding travelers’ perceptions, behaviors and expectations. Drawing on data from travel narratives, the purpose of this study is to examine the destination image of Istanbul as revealed in Western travel blogs. In addition, this study aims to identify the demographic characteristics of travelers who are more likely to engage in destination blogging activities.Design methodology/approachA deductive content analysis approach was used on a sample of travel blog entries retrieved from TravelPod.com. Based on the dimensions and attributes of destination image identified by Beerli and Martín (2004), a coding scheme was established to guide the coding process.FindingsThe findings suggest that the online destination image of Istanbul is generally positive. Specifically, the destination is mainly appreciated for its cultural and historical heritage, as well as for its tourist infrastructure. However, the findings also highlight some issues that concern Western travelers, such as safety and traffic congestion.Originality/valueThis study is timely as it explores the online destination image of a key destination in a period of instability. The findings are expected to offer insights for destination management organizations in Turkey on how Western travelers view Istanbul as a tourist destination. These insights are also important to help policymakers and tourism destination marketers design effective strategies.
Obstetric complications and delays in seeking emergency care in poor settings of northern India
Authors: Khan Nizamuddin 
Published: July 2018

Purpose
Huge gap exists between demand and supply of seeking health care leads to remain high maternal mortality in rural areas of Uttar Pradesh, India. The purpose of this paper is to make an effort in this direction.

Design/methodology/approach
This paper draws on Three Delays Model to understand the reasons behind poor maternal health outcomes among 964 currently married women aged 15–34, given birth in last two years preceding the survey including six case studies in poor settings of Northern India.

Findings
Receiving minimum four antenatal care and identifying the severity of obstetric complications during pregnancy was quite low (7 and 34 per cent, respectively). Major delay in seeking care in district was decision delay (average four days) followed by arranging transportation (average 4 hours) and start treatment within an hour after reaching health facility. Health services and trained human resources are mainly concentrated at towns and poor supply of drugs and equipment in labour room is always in demand at primary level in the district in area. Delays in decision making, travel and treatment compounded by ignorance of obstetric complications and poor healthcare infrastructure are the major contributing factors of maternal deaths in the district in area.

Originality/value
Interventions to improve timely seeking of medical care for obstetric complications may need to more effectively target husbands and family members rather than women. Strengthening of primary and secondary level facilities and timely referral to tertiary level care can play a crucial role in improving obstetric care in the district in rural areas.

Authors: Zhang Gangqiang , Zeng Xiangqiong , Ren Tianhui , Heide Emile van der 
Published: July 2018

Purpose
The purpose of this paper is to investigate the tribological performance of graphene oxide (GO) sheets as water-based lubricant additive when ultra-high molecular weight polyethylene (UHMWPE) plates slid against 316L stainless steel ball using a reciprocating tribometre.

Design/methodology/approach
The factors influencing the tribological performance were considered, including the viscosity of the GO dispersion, normal load, sliding velocity and the roughness of UHMWPE. The surface microstructure and properties of UHMWPE were studied by means of scanning electron microscopy, laser confocal microscopy, Raman spectroscopy and contact angle measurements.

Findings
The results revealed that the GO dispersion reduced friction and sliding-wear. The surface images of the wear UHMWPE plates indicated that GO sheets were prone to adsorption on the surface and form a thin physical tribofilms at the substrate.

Originality/value
Based on the experimental findings for the evolution of the microstructure morphology and the development of subsurface cracks, less debris and cracking can be observed in the UHMWPE plates lubricated by GO dispersion.
Cameroonian perspectives on entrepreneurship: discovering subcultural heterogeneity
Authors: Valliere Dave 
Published: July 2018

Purpose
This paper aims to explore cultural attitudes and beliefs about entrepreneurship in the southwestern region of Cameroon. This study also identifies the existence of subcultural variations with important implications for the development of entrepreneurial activities in Cameroon.

Design/methodology/approach
The paper uses the hybrid qualitative/quantitative Q methodology to survey and analyze a purposively diverse sample of individuals and thereby discover subcultural structures and patterns to the attitudes and beliefs that exist in Cameroonian culture.

Findings
This study discovers three distinct subcultures that differ significantly in their attitudes and beliefs about entrepreneurship. These subcultures can neither be predicted from commonly used national measures of cultures, such as those of Hofstede, nor are they directly attributable to regional effects.

Research limitations/implications
The author calls into question the continuing use of national culture as a construct in explaining and predicting entrepreneurial activities, through discovery of subcultures at odds with national measures. Further research should be undertaken to assess the prevalence within Cameroonian society of the three widely different subcultures identified here.

Practical implications
This paper highlights the importance of incorporating subcultural variations in attitudes and beliefs (whether regional, tribal or other) in the development and implementation of public policies to affect national entrepreneurship.

Originality/value
The paper applies a novel methodology to qualitatively explore the subjective variations in the meaning and value of entrepreneurship in Cameroonian society, and to quantitatively develop a structure or typology to these variations.
Why do firms centralise their strategic decision-making during crisis? A qualitative study
Authors: Bakonyi Zoltan 
Published: July 2018

PurposeAlthough decentralisation during crisis is more beneficial in the long run, still economic downturn increases the probability of centralisation. The purpose of this paper is to understand the sub-micro reasons of centralisation during recession.Design/methodology/approachTo answer the research question, a qualitative methodology was applied based on interviews with senior managers of six English and seven Hungarian manufacturing companies.FindingsIn the time of crisis, companies centralise because they would like to gain efficiency. The short-term advantages of concentration of authority (such as whole company focus, easier communication and higher decision speed) override its longer term downsides such as less innovation and flexibility.Practical implicationsCost cutting-driven centralisation can always generate faster results than a hazardous sales increase-driven decentralisation. A rapid centralisation can seem a safer and better choice than a stronger innovative capability of which results can be harvested only in the future. If companies centralise in the time of crisis and delegate during prosperity, adaptation to economic cycles can be crucial. This can gain competitive advantage if the companies can perceive economic situation and restructure their authority better than their competitors.Originality/valueThe paper would like to contribute to the quantitative-dominated literature with a descriptive, qualitative study analysing the root causes of change in concentration of authority.
Unintended human-personal self-destruction: can we save ourselves?
Authors: Hiwaki Kensei 
Published: July 2018

PurposeThis paper aims to explain the modern unintended human-personal self-destruction and the importance of diverse society-specific holistic cultures (“native cultures”) and social value systems as the remedy.Design/methodology/approachThis paper is a viewpoint, as both the explanation and the proposed remedy are based on the present author’s historical, theoretical and normative considerations.FindingsFirst, the author’s interpretation of pre-modern to modern Western societies reveals that some important pre-modern Western values are given to the modern era as part of the market value system. Second, some Mercantilist ideas have strong influences on Classical economic theory and methodology. Third, the modern Western value system – the market value system – corresponds to the Core Synergism of Modern Civilization or the complex driving force of Modern Civilization.Social implicationsThis paper is designed to facilitate reflection on the excessive emphasis on economic/market values.Originality/valueThe present author’s normative framework for social value system (“integral harmony”) is used for explaining a likely remedy of the unintended human-personal self-destruction. Also, for solving the human-personal predicament, this article integrates native culture, balance and harmony into economic thinking to promote sustainable development for a viable human future. Concluding remarks provide a summary for clarification of the remedy.
Dietary inflammatory index in relation to obesity and body mass index: a meta-analysis
Authors: Kord Varkaneh Hamed , Fatahi Somaye , Tajik Somaye , Rahmani Jamal , Zarezadeh Meysam , Shab-Bidar Sakineh 
Published: July 2018

PurposeStudies investigating the association between dietary inflammatory index (DII) and body mass index (BMI) have led to inconsistent findings. Therefore, to decisively conclude, this paper aims to clarify the relationship between DII and obesity by performing meta-analysis.Design/methodology/approachPubMed, Scopus and Google Scholar were searched up to July 2017 using key words selected from Medical Subject Headings and other related keywords to identify all relevant articles. In total, 22 articles were entered into the meta-analysis; 22 studies compared the mean of BMI among subjects with highest versus the lowest DII and 4 studies had data on the hazard risk (HR) or odds ratio (OR) for obesity.FindingsA meta-analysis on included studies indicated a significant association on either mean differences (MD) in BMI (MD = 0.811; 95 per cent CI: 0.365-1.256;p: 0.0001) or obesity OR (OR: 1.310; 95 per cent CI: 1.144-1.500;p= 0.000) by comparing the highest and lowest DII categories. Between-study heterogeneity was high (Cochrane Q test,p< 0.001, I2= 98.1 per cent, df = 21, τ2= 0.9273), and only dietary assessment methods could explain the source of heterogeneity in which 24-h dietary recalls were homogeny (I2= 8.4 per cent, df = 2,p= 0.335).Originality/valueThe results of the present meta-analysis suggest that adherence to high DII score increased BMI and obesity. More prospective studies in different populations are needed to better clarify this relation.
The information literacy and continuous professional development practices of teachers at a Jewish Day School
Authors: Cogan Aviel , Martzoukou Konstantina 
Published: July 2018

Purpose
The purpose of this study is to investigate how in-service teachers within the context of an American Jewish day school perceive, practice and develop Information Literacy (IL) as a sociocultural practice and through Continuing Professional Development (CPD). A research gap exists in relation to empirical studies which examine sociocultural IL practices and the CPD learning experiences of in-service teachers within the professional environment of their work. Two emergent and compatible frameworks for investigating teachers’ IL practices and CPD in context are identified and discussed within that context: the sociocultural approach and the interactive CPD model.

Design/methodology/approach
The research adopted an interpretivist phenomenological perspective. Semi-structured in-depth interviews were conducted with six teachers to explore their IL experiences. Questions addressed the participants’ previous background, the working culture of the school, approaches to learning and developing new knowledge, sources and methods of obtaining work-related information, IL practices and the differences between IL and CPD practices.

Findings
Although teachers value the role of IL in their professional lives and they have confidence in their performance of it, they remain confounded by the IL terminology. Within the teachers’ everyday working environment, the primacy of social and embodied information and the centrality of information sharing demonstrated the social and experiential nature of learning and the significance of contextualisation to IL development. The study found IL, CPD and learning to be inseparable, as they intersected within a single, organic situated learning practice of becoming an expert in context.

Originality/value
This study makes valuable contributions to theory by supplying empirical evidence of sociocultural IL practices, linking the currently disparate scholarships on IL, CPD and learning and providing suggestions for future research. In addition, the study demonstrates alternative avenues for developing teachers’ IL and offers recommendations for supporting their CPD.
Family bliss or blitz? Parents’ and children’s mixed emotions towards family holidays
Authors: Gram Malene , Therkelsen Anette , Larsen Jacob Roesgaard Kirkegaard 
Published: July 2018

Purpose
This paper aims to explore mixed emotions experienced by parents and children on holiday, how they are dealt with and how they influence the way “family” is “staged” and “done”.

Design/methodology/approach
This paper draws on 24 qualitative interviews with Danish parents and a questionnaire study reporting answers from 66 Danish children (11-15-year-old).

Findings
Problems external and internal to the family are identified and the latter are associated with more unease particularly among parents. This paper shows that parents invest significant narrative efforts in transcending gaps between ideals and practices. Also children are aware of the gaps between ideals and practices; they seem more matter-of-fact, however, regarding critical aspects of holidays.

Research limitations/implications
The informants of the study solely represent two-parent hetero-sexual families of Danish origin, and so inclusion of a wider range of families would have added interesting perspectives. Furthermore, children’s perspectives on critical holiday incidents need further research.

Practical implications
Creators of family holiday products and marketing should present a more nuanced imagery taking a more diverse approach to what “family” on holiday looks like. They could take up the challenge of depicting a broader range of family situations, also showing less harmonious moments, using humour, and showing opportunities for some “alone time” for both parents and children should relational overload happen. Also occasional “wifi-free” moments seem to be much appreciated by all family members, and development of offline family experiences would seem to strike a chord.

Social implications
The contemporary paradigm of intensive parenting along with strong ideals for family holidays make it essential for parents to narratively deal with and legitimize and transform less happy moments. To take pressure off contemporary families, it is important to bring to the fore the less glossy aspects of family holidays.

Originality/value
The originality of this paper is to illustrate the strong efforts applied by families to keep up a certain front to be the family that “ought to be” by nurturing and narrating positive emotions in relation to family holidays. The inclusion of children’s voices gives insights into children’s annoyance with parents’ rowing, relational overload and parents’ occasional lack of attention to children, for example through parental use of mobile phones during holiday togetherness.
