A Flexible Approach to Semantic Annotation Systems for Web Content

In this paper we propose a flexible approach that supports heterogeneous requirements on systems for the semantic annotation of web content. The flexibility of the approach originates from a model based on the definition of abstract events, which captures at the logical level the main interactions occurring in a system for combined management of ontologies and web content. Application-specific semantics is then provided operationally as an assignment of handlers to these events. While the abstract events are rather coarse-grained to reduce prior commitment, preconditions on the handlers express application-specific distinctions based on contextual information associated with each specific event. Although the possibility to define completely new handlers guarantees the generality of our approach, we foster convention over configuration by providing a set of default handlers, which can be customized by filling their extension points. The use of customizable handlers, whether or not the default ones, reduces the development effort and guarantees consistent user experience despite evolving requirements. A comprehensive framework for semantic annotation of web content has been realized and will be hereafter introduced. Copyright © 2015 John Wiley & Sons, Ltd.     

Adolescents' sustainability concerns and reasons for not consuming sustainably

Many consumers report being concerned about sustainability but they do not necessarily consume in a sustainable manner. Understanding why this occurs is vital to encouraging sustainable consumption practices. Understanding the phenomenon in relation to adolescents is particularly important. In addition to being a significant segment of current consumers, adolescents are learning consumption habits and preferences that they will carry into adulthood. This research contributes to the domain by fulfilling two research objectives. The first objective was to develop and use a scale for measuring adolescents' sustainability concerns (ASC). The second objective was to identify and examine adolescents' reasons for not consuming sustainably. The research used a three‐stage multi‐method design that included small group interviews and two online surveys with adolescents aged 12 to 17 years. The ASC scale that we produced identifies 14 key sustainability concerns across the dimensions of environment, well‐being and society. The reasons for not consuming sustainably varied across these dimensions. For example, the most frequently reported reasons in the environmental dimension included cost and convenience whereas peer pressure and hedonic preferences were the dominant reasons for well‐being. More broadly, three groups of reasons for unsustainable consumption emerged. These included (i) limited application of sustainability concerns across consumption; (ii) deviating from concerns due to competing priorities; and (iii) limiting or eliminating personal responsibility. The contributions of this research have theoretical, methodological and practical implications for consumer researchers, social marketers and policy makers.     

Domestic Violence Against Rural Women in Colombia: The Role of Labor Income

This paper analyzes the effect of women’s earnings on domestic violence in rural Colombia during the period 2009–2013. To this end, it builds an indicator of domestic violence against women at the municipal level, based on the number of visits of women who attended health facilities where a report on suspected domestic violence was issued by their physician, which overcomes the bias introduced by self-reporting victims. Results indicate that greater income generation by women in rural areas in most economic activities (coffee, fruits, commerce, and industry) decreases domestic violence, while in services, the opposite occurs. The latter could be the result of the mainly menial jobs women perform in this sector, which may be undervalued in their homes, thus making them more vulnerable. The study also finds that improvements in the municipality’s economic activity and access to education contribute to the reduction of domestic violence against women.     

Can the Retailer’s ICT Enhance the Impact of Service Recovery Efforts on Customer Satisfaction?

Abstract

Service recovery remains a topic of considerable interest for both academics and practitioners. This paper aims to explore the relations between recovery efforts and causal attributions, satisfaction, and both conventional and online word-of-mouth, as well as the moderating role of information and communication technologies (ICT) on the relationship between retailer’s efforts and satisfaction with the service recovery. On a sample of 336 retail customers who experienced service failure, we use SEM and multigroup analysis. As a result of the data analysis, there is evidence supporting the positive impact of attributions and recovery efforts on satisfaction, and the influence of the latter on both conventional and online word-of-mouth. Furthermore, the moderating influence of technology in the “recovery efforts-satisfaction” relationship is evidenced. Practical implications for retail managers and further research are presented.     

Integrating embeddedness with dynamic capabilities in the internationalisation of fashion retailers

The paper presents an integration of the theoretical approaches of embeddedness and dynamic capabilities. Based on in-depth interviews with key informants of international fashion retail companies we show that dynamic capabilities enhance different types of embeddedness at different levels. Generic dynamic capabilities of adaptability and knowledge management play a role as they affect retailer-specific capabilities and societal, network and territorial forms of embeddedness. Integrating the two theoretical approaches provides new and deeper understanding of the nature of retail internationalization.     

Exploring social change through social media: The case of the Facebook group Indignant Citizens

This study examines the role of social media in facilitating the network of a social movement, the novel forms of exchange networks that are fashioned by participants of this movement and the drivers and effects of individuals’ engagement therein. Specifically, using the lens of political consumerism, we look at the movement of self‐described Indignant Citizens in Greece to reveal the underlying motivations for participants to engage in this social movement, the dynamics of their engagement and the ways in which Indignant Citizens’ online presence enables identity expression, community building and social change. We draw on interpretive analysis of findings from eight focus groups with members of Indignant Citizens. The findings reveal how this movement and the shared identity developed amongst its members empower our participants by giving them a voice and engage them in role mobilization, drive specific actions towards the conceptualization of a shared utopia and provide them with a platform to organize action and employ desired practices for the co‐creation of useful and gratifying exchanges.

Tourist preferences for rural house stays: Evidence from discrete choice modelling in Spain

Although the appeal of rural houses for tourists lies mainly in the natural surroundings and their intrinsic rural characteristics, there are other factors which are also important such as their size, type of building, quality of equipment, services and activities offered. To evaluate the tourists' preferences for these potential or effective attributes, a stated preference experiment was conducted in the Northwest area of the Region of Murcia and the data are analysed using discrete choice modelling methodology. Consistent specifications for multinomial logit and mixed logit models that consider variations in tastes within tourists' preferences are found. The results could be of use to promoters and owners of rural houses when planning marketing and promotional campaigns or when taking effective investment decisions.     

Nutrient consumption and household income in rural Mexico

We estimate the income elasticity for a variety of macro- and micronutrients using a sample of poor rural households in Mexico. The nutrient-income elasticity is estimated using both parametric and semiparametric methods. A special focus is placed on the nonlinearity of the relationship between nutrient intake and income and on measurement error and endogeneity issues. One major finding is that income elasticity for calories is close to zero when we control for measurement error issues. For some nutrients, namely fats, vitamin A and C, calcium, and heme iron, we find a sizeable positive income elasticity robust to the choice of the estimator and percentiles at which it is evaluated. These nutrients are also those for which we find the largest deficiency in our sample. In addition, we find that for the poorest households in our sample, the deficiency of total energy, protein, and zinc is not accompanied by a positive income elasticity.     

Investment rigidity and policy measures

This paper assesses the impacts of decoupled government transferson production decisions of a sample of Kansas farms. Our empiricalanalysis is based on a reduced-form application of the dualmodel of investment under uncertainty developed by Sckokai,which is extended to a consideration of irregularities in thecapital stock adjustment cost function. To do so we adopt thethreshold regression methods proposed by Hansen. The econometricresults support the existence of three regimes characterisedby different economic behaviour. Our analysis suggests thatin a dynamic setting that allows for irregularities in the capitaladjustment cost function, decoupled transfers can have a powerfulinfluence on production decisions. The dynamics of the stockof capital cause this influence to grow over time.
