Why do they do that? Motives and dimensions of family firms’ CSR engagement
Authors: Izzo Maria Federica , Ciaburri Mirella 
Published: September 2018

PurposeThis paper aims to explore the role of socioemotional wealth (SEW) in family firms’ (FFs) corporate social responsibility (CSR) engagement and practices. The authors draw on the notion of “Socioemotional endowment” (Gomez-Mejiaet al., 2010), to interpret how the different dimensions of the FIBER model impact on the instrumental, moral or relational motives that push companies toward CSR.Design/methodology/approachThe authors develop an integrated framework that analyzes motives of CSR practices (distinguishing between moral, instrumental and relational ones) and dimensions of FF’ SEW. The idea is that it is not possible to analyze the CSR attitude of FFs without distinguishing among the five dimensions of SEW (family control and influence; identification of family members with the firm; binding social ties; emotional attachment; and renewal of family bonds to the firm through dynastic succession).FindingsThe authors posit that FFs are particularly likely to engage in instrumental, moral or relational CSR practices depending on the FIBER dimension that they consider as primary reference point to achieve the goal of preserving SEW. In particular, out of the five FIBER dimensions, relational and instrumental motives appear to be more present in firms’ priority, when they deal with CSR activities.Originality/valueMost of the literature on CSR and FFs concentrates on the differences between family and non-family firms (non-FFs) in approaching social responsible practices. Instead of debating whether FFs are more or less socially responsible than non-family organizations, the authors add to this literature by arguing that it is much more relevant to analyze which approach family firms (as an heterogeneous group) are more likely to adopt in relation to CSR. In so doing, they contribute to FFs studies on sustainability, by demonstrating that CSR engagement can be differently influenced and interpreted through the five dimensions of the FIBER model.
Sustainable tourism certification in the African hotel sector
Authors: Spenceley Anna 
Published: September 2018

Purpose
The purpose of this paper is to review the current status of certification and certified hotels on the African continent, and to discuss the implications for mainstreaming sustainable tourism on the continent.

Design/methodology/approach
The research design focused on a literature review and an online survey. The survey was used to consult stakeholders on options for incentives, and future interventions, which was distributed to 80 stakeholders from the government, certification bodies, intergovernmental agencies and NGOs. The survey resulted in 41 complete responses from 18 countries.

Findings
The study identified nine African certification programs, and nine international certification programs operating in Africa. Collectively, the African and international certification programs have certified at least 715 accommodation facilities in 19 African countries, against their environmental, social and economic criteria. So only a very small proportion of all hotels in Africa have been certified (certainly less than 3.4 per cent) and that these are patchily distributed across the continent. A number of incentives have been used in Africa, including marketing and promotion; interest free loans for new technologies; preferential inclusion in tour itineraries; free or discounted application processes; and technical support. Consultees suggested that hotels were generally motivated to seek certification to: promote their achievements to environmentally conscious clients and avoid negative criticism, and save money by conserving resources. However, hotels do not understand the financial benefits of sustainable practices.

Research limitations/implications
Research limitations include the modest sample size. For the purposes of this research, there was a greater emphasis in targeting a modest number of key respondents who could provide expert opinions on the topic, rather than a more extensive sample size of lower quality.

Practical implications
Practical implications include recommendations of incentives and approaches to mainstream tourism certification in Africa. These include promoting programmes and their returns on investment more broadly, promoting market advantage for certified accommodation (i.e. preferential marketing or concession terms) and the value of integrating sustainability criteria into national and regional quality-rating standards.

Originality/value
This is the first study of its kind to analyse certification on the African continent, which was presented at the Climate Change Summit (COP22) in Morocco in 2016 and the BEST EN Think Tank XVII in June 2017.
What justification is there for including the mass suicide of Jonestown as part of a Guyana dark tourism narrative in 2025?
Authors: Sinclair Donald 
Published: September 2018

Purpose
The Jonestown massacre of 1978 was the largest such event in modern history; it assumes the status of a prototype in many discussions of cult dynamics and mass suicide. This paper aims to make the case that Jonestown should be memorialised and made into a dark tourism attraction.

Design/methodology/approach
This paper is principally the outcome of secondary research conducted over a number of years on the theme of dark tourism. The paper also benefited from direct interviews and conversations with political and ex-military personnel in Guyana who were in some way involved with Jonestown.

Findings
The research establishes that Jonestown remains a matter of great sensitivity and even national embarrassment, with many in the tourism sector reluctant to highlight what they regard as a very negative association, in the market, of Guyana with Jonestown and Jonestown only.

Practical implications
Expressed in context, the paper discusses the place of Jonestown in dark tourism and proposes an operational formula by which the semiotic of Jonestown, as contained in the tourist narrative, transforms tourism into catharsis.

Originality/value
For the author, Jonestown is tourism-imperative because not much longer after that apocalyptic event, the “Jonestown massacre” became a reference in the discourse on dark tourism. Jonestown is too large and archetypal an event to escape research and discussion of its place in the realm of dark tourism. This paper therefore explores, from both theoretical and policy perspectives, the ways in which the narratives of dark tourism can serve to expiate guilt by confronting it and therefore still deserve a place in the tourism imaginary of 2025. As such, the paper should be of value to not only scholars and researchers but also those engaged in tourism planning and destination management.

Published: September 2018

Abstract

The introduction of a non‐native species frequently has adverse direct effects on native species. The underlying mechanisms, however, often remain unclear, in particular where native and invasive species are taxonomically similar.

We found evidence of direct competitive interactions between a globally distributed invasive species (the Pacific oyster, Magallana gigas) and its native counterpart (the European oyster, Ostrea edulis). We also discovered that the competitive outcome differed between different habitat types and orientation by identifying context‐dependent responses driven by environmental conditions and stress (i.e. intertidal compared to subtidal habitats; and vertical versus horizontal substratum). This is particularly important because the European oyster is threatened, or in decline, throughout most of its range, and restoration efforts are underway in many regions.

We combined experimental manipulations and stable isotope analysis (SIA) to identify the direct effects of competition and the mechanisms by which the invasive and native species compete. We identified negative effects of the invasive species on the native oyster, but these were limited to the subtidal habitat (lower stress environment) and determined by substratum orientation (habitat structure). Crucially, we found that effects of the invasive species on the native species were not always negative and under certain conditions (e.g. on vertical substrata) were positive. Shifts in isotopic niches of both species when co‐occurring, alongside mixing models, indicate that exploitative competition for food is most likely to underpin niche partitioning between both species.

We have identified different foraging strategies under different contexts, and our findings highlight the importance of exploitative competition as a driving mechanism behind the co‐occurrence of two seemingly functionally similar consumers. The combination of experimental manipulations with SIA is a powerful tool, and we illustrate how this approach should be incorporated, into multiple environmental contexts at appropriate scales, to more accurately predict impacts of the spread of invasive species on native communities.
Are there missed opportunities for occupational therapy for people with dementia? An audit of practice in Australia

Published: September 2018

Background/aimRandomised trials have demonstrated that occupational therapy can delay functional decline, improve quality of life and increase leisure participation in people with dementia. However, surveys conducted with occupational therapists suggest that clinical practice does not reflect the type of intervention shown to be effective in research studies. Case note audits can be used to quantify practice and demonstrate how and where provision of care could improve without the potential bias associated with self‐report.MethodA total of 87 occupational therapy case notes were audited from different service contexts in two states in Australia. The case notes were reviewed against criteria including duration of service, assessments conducted and interventions used. Descriptive statistics were used to present the data and examine associations between intervention, age of the person with dementia and whether or not the person lived alone.ResultsServices tended to be short‐term with an average of 2.1 consultations per referral. The most common assessments related to home safety, falls risk and function. Intervention most commonly focussed on referrals to other services, environmental modification advice and assistive device prescription.ConclusionThis audit reveals that current occupational therapy practice for people with dementia focusses on assessment and management of risk and is usually limited to a couple of consultations. Future work should seek to evaluate if such approaches to care are effective for people with dementia.

Published: September 2018

SummarySmall eukaryotes (0.2–20 μm cell‐size) represent a significant fraction of the microbial plankton community in shelf waters of NW‐Spain. The community composition of small eukaryotes living at the surface and at the base of the photic zone was analysed by means of 18S rDNA high‐throughput sequencing on a circa‐monthly basis over a 23 months period. Ostreococcus was the most abundant taxon in surface waters, showing marked peaks in read abundance in spring and late summer, while Syndiniales dominated at the base of the photic zone. A well‐defined seasonal pattern of community composition, linked to the succession of the dominant taxa, was found in surface waters. Seasonality was less apparent at the base of the euphotic zone. Temporal changes in abiotic factors significantly correlated with changes in community composition in surface (r = 0.71) and at the base of the photic zone (r = 0.38). Changes in community composition significantly correlated with changes in community function‐related variables (including biomass, primary production and respiration) only in surface water (r = 0.36). Co‐occurrence network analyses revealed 45 significant interspecies associations among the 50 most abundant taxa with highly connected OTUs belonging to cryptophyceans. The network topology, with small‐world characteristics, suggests a stabilizing role of biotic interactions to environmental disturbance.
Assessing Consumer and Producer Preferences for Animal Welfare Using a Common Elicitation Format
Authors: Latacz‐Lohmann Uwe , Schreiner Julia Anette 
Published: September 2018

AbstractWe assess pig farmers’ willingness‐to‐accept (WTA) higher farm animal welfare (FAW) standards and consumers’ willingness‐to‐pay (WTP) for thus enhanced standards. The analysis is based on discrete choice experiments with nearly identical choice sets for both farmers (N=140) and consumers (N=554). Based on preference estimates from a random parameter logit (RPL) model, supply and demand curves for high‐welfare pork in Germany are estimated and market equilibria are derived for alternative levels of FAW. We find that estimates of consumer WTP are significantly positive for all FAW attributes: consumers value more surface space per pig, more bedding and manipulable material, less surgical interventions and shorter transportation times. In contrast, our model revealed significant producer WTA estimates only for surface area per pig and the amount of bedding material on offer, but not for the other FAW attributes. Farmers who expect to continue farming and engage in direct marketing are more likely to adopt higher FAW standards. Male consumers and those who find price more important than brand, origin or taste are less likely to buy high‐welfare pork, as are consumers who never purchase organic meat products. Market simulations for high‐welfare pork indicate increasing divergence between demand and supply with rising FAW standards. We estimate a market share of 44.6% for pork produced in compliance with an entry‐level FAW programme with standards only slightly above the legal minimum. Programmes with more demanding standards are estimated to gain much smaller market shares.

AimsThe aims of the current study were: (i) to examine the prescribing of preventative medication in a cohort of people with advanced lung cancer on hospital admission and discharge across different healthcare systems; and (ii) to explore the factors that influence preventative medication prescribing at hospital discharge.MethodsA retrospective cohort study was conducted across two centres in the UK and the US. The prescribing of preventative medication was examined at hospital admission and discharge for patients who died of lung cancer. A zero‐inflated negative binomial regression model was used to examine the association between preventative medications at discharge and patient‐ and hospital‐based factors. The classes of preventative medication prescribed included were: vitamins and minerals, and antidiabetic, antihypertensive, antihyperlipidaemic and antiplatelet medications.ResultsIn the UK site (n = 125), the mean number of preventative medications prescribed was 1.9 [standard deviation (SD) 1.7) on admission, and 1.7 (SD 1.7) on discharge, and in the US site (n = 191) the mean was 2.6 (SD 2.2) on admission and 1.9 (SD 2.2) on discharge. The model found a significant association between the number of preventative drugs prescribed on admission and the number on discharge; it also found a significant association between the total number of drugs prescribed on discharge and the number of preventative medications on discharge. Other indicators related to patient and hospital factors were not significantly associated with the number of preventative medications supplied on discharge.ConclusionsThe use of preventative medication was common in lung cancer patients, despite undergoing discharge. Patient‐ and hospital‐based factors did not influence the prescribing of preventative medication.

Published: September 2018

AbstractThe main purpose of our study was to examine whether autonomous training through the use of technologies could be associated with improvements in selective attention, visuospatial short‐term memory and visuospatial processing in students with Down Syndrome (DS). In addition, our study aimed to analyse how the improvements in selective attention and visuospatial short‐term memory tasks could predict improvements in visuospatial processing. Twenty‐six children and adolescents with DS who belong to specialized schools for ID participated in the study. Three different mobile applications, Bubbles (selective attention), Pairs and Learn (visuospatial short‐term memory) and Tangram (visuospatial processing) developed by Smile and Learn were used during a three‐month period by the students. The results showed significant improvements through training in both, Pairs and Learn and Tangram, whereas there was no significant improvement in Bubbles. The results also showed that Pairs and Learn performance could predict a 36% variance in Tangram one. Cognitive and educational implications of these results are discussed.
Understanding the relationship between levels of mobile technology use in high school physics classrooms and the learning outcome
Authors: Zhai Xiaoming , Zhang Meilan , Li Min , Zhang Xuejie 
Published: September 2018

AbstractMobile technology has been increasingly adopted in science education. We generally assume that more innovative use of mobile technology leads to a greater learning outcome. Yet, there is a lack of empirical research to support this assumption. To fill in the gap, we drew upon data from 803 high school students who had used mobile devices for five months in physics classrooms. Using the SAMR model (ie, Substitution, Augmentation, Modification, and Redefinition), we distinguished their uses into two levels: Substitution (replacing traditional instructional approach with mobile technology without functional improvement), and augmentation (enhancing instruction with affordances provided by mobile technology). Using Hierarchical Linear Modeling analysis, we found that the augmentation level of use was positively correlated with the physics learning outcome, but the substitution level of use was not. We further identified four sub‐types of uses within the augmentation level. We found that after‐school remediating activities and student–teacher displaying activities were positively correlated with student physics achievement, but teacher‐assigned activities had no significant correlation and learning aid activities had a negative correlation with the learning outcome. This study provided empirical evidence to support the assumption that a higher level of mobile technology use may be related to a greater learning outcome and that the impact of mobile technology may be determined by multiple factors such as who initiates the use and whether the use enhances or distracts students' knowledge construction.

AbstractAnaplasia may be identified in a subset of tumors with a presumed pilocytic astrocytoma (PA) component or piloid features, which may be associated with aggressive behavior, but the biologic basis of this change remains unclear. Fifty‐seven resections from 36 patients (23 M, 13 F, mean age 32 years, range 3–75) were included. A clinical diagnosis of NF1 was present in 8 (22%). Alternative lengthening of telomeres (ALT) was assessed by telomere‐specific FISH and/or CISH. A combination of immunohistochemistry, DNA sequencing and FISH were used to study BRAF, ATRX, CDKN2A/p16, mutant IDH1 p.R132H and H3‐K27M proteins. ALT was present in 25 (69%) cases and ATRX loss in 20 (57%), mostly in the expected association of ALT+/ATRX‐ (20/24, 83%) or ALT‐/ATRX+ (11/11, 100%). BRAF duplication was present in 8 (of 26) (31%). H3‐K27M was present in 5 of 32 (16%) cases, all with concurrent ATRX loss and ALT. ALT was also present in 9 (of 11) cases in the benign PA precursor, 7 of which also had ATRX loss in both the precursor and the anaplastic tumor. In a single pediatric case, ALT and ATRX loss developed in the anaplastic component only, and in another adult case, ALT was present in the PA‐A component only, but ATRX was not tested. Features associated with worse prognosis included subtotal resection, adult vs. pediatric, presence of a PA precursor preceding a diagnosis of anaplasia, necrosis, presence of ALT and ATRX expression loss. ALT and ATRX loss, as well as alterations involving the MAPK pathway, are frequent in PA with anaplasia at the time of development of anaplasia or in their precursors. Additionally, a small subset of PA with anaplasia have H3‐K27M mutations. These findings further support the concept that PA with anaplasia is a neoplasm with heterogeneous genetic features and alterations typical of both PA and diffuse gliomas.
