Understanding relationship quality in hospitality services
Authors: Sanchez-Franco Manuel J. , Cepeda-Carrion Gabriel , Roldán José L. 
Published: February 2019

Purpose
The purpose of this paper is to analyze the occurrence of terms to identify the relevant topics and then to investigate the area (based on topics) of hospitality services that is highly associated with relationship quality. This research represents an opportunity to fill the gap in the current literature, and clarify the understanding of guests’ affective states by evaluating all aspects of their relationship with a hotel.

Design/methodology/approach
This research focuses on natural opinions upon which machine-learning algorithms can be executed: text summarization, sentiment analysis and latent Dirichlet allocation (LDA). Our data set contains 47,172 reviews of 33 hotels located in Las Vegas, and registered with Yelp. A component-based structural equation modeling (partial least squares (PLS)) is applied, with a dual – exploratory and predictive – purpose.

Findings
To maintain a truly loyal relationship and to achieve competitive success, hospitality managers must take into account both tangible and intangible features when allocating their marketing efforts to satisfaction-, trust- and commitment-based cues. On the other hand, the application of the PLS predict algorithm demonstrates the predictive performance (out-of-sample prediction) of our model that supports its ability to predict new and accurate values for individual cases when further samples are added.

Originality/value
LDA and PLS produce relevant informative summaries of corpora, and confirm and address more specifically the results of the previous literature concerning relationship quality. Our results are more reliable and accurate (providing insights not indicated in guests’ ratings into how hotels can improve their services) than prior statistical results based on limited sample data and on numerical satisfaction ratings alone.
Leaving Lake Wobegon: firearm-related education and training for medical and mental health professionals is an essential competence
Authors: Pirelli Gianni , Gold Liza 
Published: February 2019

PurposeFirearm-involved violence and suicide in the USA, often collectively referred to as “gun violence,” has been labeled a public health problem and an epidemic, and even an endemic by some. Many lawmakers, community groups, mainstream media outlets and professional organizations regularly address gun-related issues and frequently associate firearm violence with mental health. As a result, these groups often set forth positions, engage in discussions and promote policies that are at least partially based on the widely held but incorrect assumption that medical and mental health professionals are either inherently equipped or professionally trained to intervene with their patients and reduce gun deaths. The paper aims to discuss this issue.Design/methodology/approachFurthermore, notable proportions of medical and mental health professionals self-report a level of comfort engaging in firearm-specific interventions that is often disproportionate to their actual education and training in the area. This type of overconfidence bias has been referred to as the Lake Wobegon Effect, illusory superiority, the above average effect, the better-than average effect or the false uniqueness bias. While medical and mental health professionals need to serve on the front line of firearm-involved violence and suicide prevention initiatives, the vast majority have not actually received systematic, formal training on firearm-specific issues.FindingsTherefore, many lack the professional and cultural competence to meet current and potential future in regard to addressing gun violence. In this paper, the authors discuss empirical studies that illustrate this reality and a novel model (i.e. the Know, Ask, Do framework) that medical and mental health professionals can use when firearm-related issues arise. In addition, the authors set forth considerations for clinicians to develop and maintain their professional and cultural competence related to firearms and firearm-related subcultures.Originality/valueThis paper provides empirical and conceptual support for medical and mental health programs to develop formal education and training related to guns, gun safety and gun culture. A framework is provided that can also assist medical and mental health professionals to develop and maintain their own professional and cultural competence.
The relativity of theory: applying theories of social psychology to illuminate the causes of the abuse of older people in care homes
Authors: Moore Steve 
Published: February 2019

PurposeThrough the lens afforded by two theories drawn from the discipline of social psychology, the purpose of this paper is to explain the evident continuing abuse of adults at risk living in care homes by the staff who should be looking after them.Design/methodology/approachBy considering existing theories and research into the reasons why vulnerable adults are abused the paper proposes the relevance of other extant theories on the degradation of moral restraint and dehumanisation of victims, and on the social psychology of intergroup relations, to the perpetration of abuse.FindingsThe paper demonstrates how theories that explain the psychology of human behaviour in certain circumstances may be usefully applied to the inveterate social problem of the abuse of vulnerable adults living in care homes.Practical implicationsThe paper offers the opportunity for the reader to consider how these theories of social psychology may be applied to explain and guide remedies to the persistent levels of abuse in English care homes, abuse that continues despite government oversight of care provided to adults who may be at risk by virtue of the activities of the statutory regulator and health and social care commissioners, and the interventions of safeguarding personnel.Originality/valueThis is a conceptual paper from which future research and theorising may arise to better understand the most fundamental causes of the abuse of older people in care homes in order to develop feasible and effective measures to overcome it.
Matching-up celebrities’ brands with products and social causes
Authors: Santos Ana Luisa , Barros Filipa , Azevedo António 
Published: February 2019

PurposeBeyond traditional brand endorsement, many celebrities have in recent years decided to launch their own product lines, which may be used to promote their own celebrity brand. Which product categories or social causes match a celebrity’s brand personality? This study aims to investigate the antecedents of celebrity–product degree of fit and willingness to pay (WTP)/make a donation in different scenarios. The manipulation of the scenarios aims to capture the role of celebrity attributes, perceived personality profiles, product involvement and acceptance of social causes.Design/methodology/approachIn total, 335 respondents answered an online questionnaire with a factorial plan corresponding to 20 different matching scenarios: five celebrities/perceived personalities (Emma Watson, Jennifer Lawrence, Kim Kardashian, Natalie Portman and Scarlet Johansson) × four types of branding scenarios (a lipstick for low involvement; a watch for high involvement; an eco-foundation for “high social acceptance” and vodka for “low social acceptance/controversial”).FindingsScarlett Johansson obtained the highest degree of fit, both for launching her own brand of lipstick or a watch. Kim Kardashian had the best degree of fit for launching her own vodka brand, while Emma Watson’s attributes confirmed that she would be seen as the ideal founder of an eco-foundation. Significant predictors of WTP/make a donation were assessed by multiple linear regression for each type of product.Practical implicationsThe paper provides recommendations that may help guide celebrity brand managers through the celebrity–product matching process.Social implicationsCelebrity branding in relation to social causes is also discussed in this paper.Originality/valueThis study explores a gap found in the literature as it explores the product match-up hypotheses within a celebrity branding context and moreover extends this investigation to social causes and products with different degrees of involvement and social acceptance.
A network view of entrepreneurial cognition in corporate entrepreneurship contexts
Authors: Thomas Nobin , Randolph Angela , Marin Alejandra 
Published: February 2019

PurposeResearch in entrepreneurial cognition has called for a better understanding of interactions between contextual variables and cognitive processes. Based on previous work done on organizational learning and social networks, the purpose of this paper is to propose a formal model in which information acquisition, distribution and interpretation are tested as a function of cognition-based trust, perceived expertise and tie strength between organizational members in two different corporate entrepreneurship (CE) types.Design/methodology/approachThe authors conduct a quantitative analysis based on network data in two companies located in India. Special procedures known as quadratic assignment procedure and multiple regression quadratic assignment procedure were used to run the correlations and multiple regressions, respectively. The authors complement this analysis with interviews and qualitative information to build a rich description in each of these cases.FindingsThe results indicate moderate support for the model. The evidence suggests that between both types of CE types, domain redefinition requires higher levels of tie strength, trust and perceived expertise. Sustained regeneration shows moderate significant results in tie strength, and cognition-based trust.Originality/valueThe authors combined insights on social network and organizational cognitive processes to analyze interactions between context and cognition. The authors were also able to compare two different companies. The authors found consistent results regarding tie strength, but the authors also found differences between both companies, which suggest that different CE types tend to require different dynamics between context and cognitive processes.
Financial indicators, informational environment of emerging markets and stock returns
Authors: Takamatsu Renata Turola , Lopes Fávero Luiz Paulo 
Published: February 2019

Purpose
The purpose of this paper is to evaluate the influence of the informational environment on the relevance of accounting information in companies traded in stock exchanges of emerging markets.

Design/methodology/approach
For this purpose, the authors calculated indicators based on figures derived from the financial statements and variables that sought to capture the influence of the economic and institutional environment. The sample consisted of publicly traded companies from 20 countries classified as emerging by Standard & Poors. Macroeconomic information was obtained through the International Country Risk Guide database. The analysis period ranged from 2004 to 2013, excluding missing data, variables considered as outliers, besides the exclusion of data from companies that presented negative equity.

Findings
It was observed that the financial variables presented signs consistent with the literature, except for the price-to-book variable and the asset change variable. The inclusion of variables related to the accounting informational environment offered evidence that the more opaque the accounting environment in the country, the lesser the ability of the profits to portray the variations of stock returns. The variable that captured the adoption of international standards was consistent with expectations, i.e. the adoption of international standards would increase the quality of accounting information, showing a positive signal. Moreover, the variable aggressiveness of the earnings was statistically significant and negative, consistent with the literature.

Research limitations/implications
The variables earnings smoothing and aversion to losses did not show the expected behaviour though, highlighting the possible limitations of these proxies used to capture the opacity of the earnings.

Originality/value
When institutional moderators were included, it was observed that the adoption of the IFRS standards positively affected the relationship, which is more relevant when the accounting figures were under its aegis. Recently, countless nations’ transition to international accounting standards has been justified by the need to use high-quality reporting standards. The research sought to contribute to strengthen this dimension, presenting evidence that the dummy variable included to capture the adoption of international standards had a positive effect on the relationship.

Published: February 2019

AbstractAntimicrobial agents have been used for eradication of Cutibacterium (formerly Propionibacterium) acnes that is an exacerbation factor of the skin disease acne vulgaris. However, the use of antibiotics is associated with an increased risk of promoting the emergence of resistant bacteria and leading to skin dysbiosis. Traditional Japanese Kampo medicines, such as Keigairengyoto, are used to treat acne. However, there is incomplete understanding regarding their functional mechanism in treatment of acne. In this study, we examined the antimicrobial and anti‐lipase activity of the Kampo medicines used empirically for acne treatment. Three oral medicines, Keigairengyoto, Seijoboufuto and Jumihaidokuto, were found to inhibit the growth of C. acnes and decrease the lipase activity. Especially, Keigairengyoto caused remarkable decrease of bacterial lipase activity. Furthermore, topical medicines such as Shiunko and Chuoko significantly decreased the lipase activity in a dose‐dependent manner, without inhibiting C. acnes growth. The topical medicines were found to inhibit the expression of gehA, which codes for extracellular lipase. Our results indicate that Shiunko and Chuoko have potential as effective acne therapeutic agents, especially because they do not promote the emergence of antimicrobial‐resistant bacteria and skin dysbiosis.
Fish culling reduces tapeworm burden in Arctic charr by increasing parasite mortality rather than by reducing density‐dependent transmission

Published: February 2019

Abstract

Two common Dibothriocephalus (formerly Diphyllobothrium) tapeworm species were significantly reduced by experimental culling of their fish host Arctic charr (Salvelinus alpinus) in a subarctic lake.

Between 1984 and 1991, funnel traps were used to cull ~35 metric tons of Arctic charr, reducing charr density by ~80%. As charr densities decreased, tapeworm prevalence and then intensity also declined over the following three decades, with D. dendriticus (formerly dendriticum) responding faster than D. ditremus (formerly ditremum). The two main hypotheses for how culling a host can decrease parasitism are reductions in parasite transmission due to reduced host density and reductions in parasite survival through increases in host mortality rates.

We found little evidence that charr density was the main driver for reduced parasite transmission. Instead, decreased survivorship in charr, initially, through fishing‐induced changes in charr age structure, and later through increased predation rates by brown trout, led to increased parasite mortality. Although brown trout, which increased significantly after fish culling, are also hosts, they are often too big for the final host birds to eat, thus becoming parasite sinks.

Synthesis and applications. Fish populations with heavy parasite burdens constitute a management problem. Our results show how fish culling can indirectly reduce transmitted parasites through increased parasite mortality. Managing overcrowded fish populations by culling can produce two desirable outcomes: an increase in fish growth rates and reduced parasite burdens.
Children’s attitudes towards peers with learning disabilities – the role of perceived parental behaviour, contact experiences and self‐efficacy beliefs
Authors: Hellmich Frank , Loeper Marwin Felix 
Published: February 2019

Children with special educational needs often feel lonely in classrooms, are less accepted by their classmates and have fewer friendships. Their classmates’ positive attitudes towards them are important for their social participation in inclusive classrooms. According to the theory of social referencing, children’s attitudes towards peers with special educational needs are influenced by the role model behaviour of their parents. Therefore, we examined the relevance of children’s perceptions of parental behaviour in terms of their attitudes towards peers with learning disabilities. This was done by investigating N = 753 children’s attitudes, depending on their perceptions of parental behaviour towards peers with special educational needs, their contact experiences and their self‐efficacy beliefs concerning their interpersonal skills. The results indicate that their attitudes are predicted by their perceptions of parental behaviour, their contact experiences and their self‐efficacy beliefs. The effect of perceived parental behaviour on children’s attitudes is mediated by their self‐efficacy beliefs.
The UK Domestic Gas Electricity (Tariff Cap) Act: Re‐regulating the Retail Energy Market
Authors: Ioannidou Maria , Mantzari Despoina 
Published: February 2019

AbstractThe UK retail energy market has witnessed multiple regulatory interventions since its liberalisation almost two decades ago. Such interventions reached their peak with the enactment of the UK Domestic Gas Electricity (Tariff Cap) Act in July 2018. The Act puts in place a requirement on the independent regulator, the Office of Gas and Electricity Markets (Ofgem), to set an absolute price cap on poor value tariffs. As such, it signals a repudiation of the overarching paradigm of consumer empowerment that has informed regulatory remedies to date. Rather than advocating for a different paradigm, this article highlights the difficulties inherent in reconciling price caps – both practically and conceptually – with the competitive process and consumer empowerment. It also discussses other instruments, not necessarily exhausted in retail price regulation, that can render affordable energy prices, without sacrificing consumer empowerment.

ObjectiveMitochondrial disease is a disorder of energy metabolism that affects 1 in 4300 adults in the UK. Pregnancy is associated with physiological demands that have implications for energy metabolism. We were interested to know how pregnancy was affected in women with mitochondrial disease, particularly those with the most common pathogenic mutation m.3243A>G.DesignRetrospective case‐comparison study.Population/SettingSixty‐seven women with genetically confirmed mitochondrial disease from the UK Mitochondrial Diseases Cohort and 69 unaffected women participated.MethodsParticipants answered questionnaires regarding each of their pregnancies. Patients were divided into two groups according to genetic mutation, with those harbouring m.3243A>G comprising a single group.Main outcome measuresPregnancy‐related complications, mode of delivery, gestational age and birthweight of newborns.ResultsOf 139 live births in the comparison group, 62 were in the m.3243A>G group and 87 were in the ‘all other mutations’ group. Pregnancies of women with the m.3243A>G mutation had significantly more gestational diabetes (odds ratio [OR] = 8.2, 95% CI 1.3–50.1), breathing difficulties (OR = 7.8, 95% CI 1.0–59.1) and hypertension (OR = 8.2, 95% CI 3.1–21.5) than the comparison group. Only half of the pregnancies in the m.3243A>G group had normal vaginal delivery, with emergency caesarean section accounting for 24.2% of deliveries. Babies were born significantly earlier to mothers harbouring m.3243A>G with 53.3% of them preterm (<37 weeks). These babies were also more likely to require resuscitation and admission.ConclusionWomen who carried the m.3243A>G mutation appeared to be at higher risk of complications during pregnancies, caesarean section and preterm delivery than the unaffected women or those with other forms of mitochondrial disease.Tweetable abstractPregnant women with mitochondrial disease – m.3243A>G mutation – are at greatly increased risk of complications and preterm delivery.
An Overview of Zoonotic Disease Outbreaks and its Forensic Management Over Time
Authors: Serrano Isa , Gomes Diana , Ramilo David , Rebelo Maria Teresa , da Fonseca Isabel Pereira , Moreira Anabela , Oliveira Manuela 
Published: February 2019

AbstractMost emerging or re‐emerging infections are vector‐borne or zoonotic and can be disseminated worldwide by infected humans or animals. They are a major public health problem and cause a great impact on economy. Zoonotic outbreaks began to be characterized in the 90s, after the creation of Europol and the FBI. Such investigations are carried by forensic pathologists and other specialists to determine whether an outbreak is natural or deliberate. This review will discuss ten zoonotic outbreaks nonrelated to wars focusing on forensic management. In conclusion, some points should be highlighted in the management of a zoonotic outbreak: (i) its diagnosis and detection by forensic pathologists and the coordination of efforts between other specialists are key factors; (ii) communication guidelines and an efficient healthcare system are crucial for any emergency response; (iii) biosafety of all specialists involved must be guaranteed.

Published: February 2019

AbstractThe retrogradation properties of lotus seed starch (LS) blended with the hydrocolloids arabic gum (AG), carrageenan (CG), guar gum (GG), and xanthan (XN) were investigated undergoing an autoclaving–cooling treatment, a model for starch retrogradation acceleration. Compared with LS alone, LS–AG showed the increases in syneresis, tan δ (more solid‐like behavior), bound water content and immobile water content, molecular weight, the intensity at 480 cm−1 in Raman spectra and the ratio of absorbance 1047 cm–1/1022 cm–1 (R1047/1022) in FT–IR spectra. The results suggested that the addition of AG tended to promote the starch retrogradation, which was related to the increased molecular migration of free water, interactions of molecular starch chains, and the formation of ordered structures. The addition of CG, GG, or XN significantly decreased the syneresis, tan δ, the intensity at 480 cm−1, and R1047/1022 values of LS, indicating the prevention of LS retrogradation. The effects of CG and XN on starch retrogradation mainly resulted from competition for water and the increased viscosity, as well as the coating effect on starch. The dominant viscosity of GG was the main factor that influenced starch retrogradation. These results showed not all hydrocolloids would retard starch retrogradation under autoclaving–cooling treatment, for which fine structures altered by different hydrocolloids were the key factors.Practical ApplicationEffects of hydrocolloids on the retrogradation of lotus seed starch were investigated undergoing an autoclaving–cooling treatment. The results will help guide the production and development of starchy foods having desirable properties by specific hydrocolloids during autoclaving–cooling process, especially to control starch retrogradation.
