AbstractBackgroundSpecies tree estimation is challenging in the presence of incomplete lineage sorting (ILS), which can make gene trees different from the species tree. Because ILS is expected to occur and the standard concatenation approach can return incorrect trees with high support in the presence of ILS, “coalescent-based” summary methods (which first estimate gene trees and then combine gene trees into a species tree) have been developed that have theoretical guarantees of robustness to arbitrarily high amounts of ILS. Some studies have suggested that summary methods should only be used on “c-genes” (i.e., recombination-free loci) that can be extremely short (sometimes fewer than 100 sites). However, gene trees estimated on short alignments can have high estimation error, and summary methods tend to have high error on short c-genes. To address this problem, Chifman and Kubatko introduced SVDquartets, a new coalescent-based method. SVDquartets takes multi-locus unlinked single-site data, infers the quartet trees for all subsets of four species, and then combines the set of quartet trees into a species tree using a quartet amalgamation heuristic. Yet, the relative accuracy of SVDquartets to leading coalescent-based methods has not been assessed.ResultsWe compared SVDquartets to two leading coalescent-based methods (ASTRAL-2 and NJst), and to concatenation using maximum likelihood. We used a collection of simulated datasets, varying ILS levels, numbers of taxa, and number of sites per locus. Although SVDquartets was sometimes more accurate than ASTRAL-2 and NJst, most often the best results were obtained using ASTRAL-2, even on the shortest gene sequence alignments we explored (with only 10 sites per locus). Finally, concatenation was the most accurate of all methods under low ILS conditions.ConclusionsASTRAL-2 generally had the best accuracy under higher ILS conditions, and concatenation had the best accuracy under the lowest ILS conditions. However, SVDquartets was competitive with the best methods under conditions with low ILS and small numbers of sites per locus. The good performance under many conditions of ASTRAL-2 in comparison to SVDquartets is surprising given the known vulnerability of ASTRAL-2 and similar methods to short gene sequences.
Crystal structure ofrac-(3aR*,9aS*)-4,4,4-trichloro-1,2,3,3a,4,9a-hexahydro-4λ5,9λ4-cyclopenta[4,5][1,3]tellurazolo[3,2-a]pyridine

The title compound, C10H12Cl3NTe, crystallizes with two crystallographically independent molecules (AandB) in the asymmetric unit. In each case, the coordination around the Te atom is distorted square-pyramidal, with the equatorial plane composed of the three Cl atoms and the C atom of the pyridinium ring. The Te atom is displaced from the mean-square plane by 0.1926 (7) and 0.1981 (8) Å, in moleculesAandB, respectivly, away from the apical C atom. The bond lengths from the Te atom to the two Cl atoms arrangedtransto each other [2.5009 (7)/2.5145 (7) and 2.5184 (7)/2.5220 (8) Å in moleculesAandB, respectivly] are substantially shorter than the third Te—Cl distance [2.8786 (7) and 2.8763 (7) Å in moleculesAandB, respectivly]. The 1,3-tellurazole ring is almost planar (r.m.s. deviations of 0.042 and 0.045 Å in moleculesAandB, respectivly). The cyclopentane rings in both moleculesAandBadopt envelope conformations with the carbon atom opposed to the (Te)C—C(N) bond as the flap. In the crystal, molecules form centrosymmetric 2 + 2 associatesviaTe...Cl interactions [3.3993 (7) and 3.2030 (7) Å]. As a result of these secondary interactions, the Te atom attains a strongly distorted 5 + 1 octahedral environment. Further, the 2 + 2 associates are bound by weak C—H...Cl hydrogen bonds into a three–dimensional framework.
Antecedents of attitudes toward the website
Authors: Alcántara-Pilar Juan Miguel , Del Barrio-García Salvador 
Published: July 2015

Purpose
– The purpose of this paper is to analyze the moderating role of the cultural dimensions of long-term orientation (LTO) and individualism (IND) on the relationships between satisfaction online, message involvement (MI) and perceived usefulness (PU) of the web site on attitude toward the web site.

Design/methodology/approach
– The authors chose a between-subjects experimental design, using culture (Spanish vs British) as the independent variable. Two versions of a web site for a fictitious tourist destination were created – one written in Spanish and the other in English. The sample comprised 491 users.

Findings
– The findings indicate that the LTO dimension moderates the relationship between satisfaction online and PU on attitude toward the web site. The relationships between MI and attitude toward the web site could not be confirmed.

Research limitations/implications
– The main limitation of this study is the comparison of only two cultures, Spain vs the UK.

Practical implications
– The key implication is that if marketers and web site designers can better understand how national cultural differences moderate the attitude formation and change process among tourists, this will enable them to market their destinations and services more effectively. National cultural differences explain the differences found in the effect of satisfaction and PU on attitude toward the web site.

Originality/value
– This study is one of the few analyzing the moderating effect of LTO and IND on three antecedents of attitude toward the web site. The original cultural values established by Hofstede (2001) were tested among the present sample to establish the extent to which they remain true today. To create an authentic browsing scenario for the experiment, a web site was specially designed for a fictitious tourist destination, with its own domain name (buyada.org). Subjects were invited to browse the site freely while carrying out the task assigned to them. This approach contributed added value to the research by simulating the real behavior of tourists who are faced with a range of choices when putting together a tourism package for a given destination.
Brand personality and purchase intention
Authors: Toldos-Romero María de la Paz , Orozco-Gómez Ma. Margarita 
Published: July 2015

Purpose
– The purpose of this paper is to analyze the effects of brand personality dimensions on purchase intention. Furthermore, the brand personality dimensions are compared to study the differences between users and non-users of 12 brands.

Design/methodology/approach
– An estimated 400 undergraduate students participated. They were given a questionnaire divided into two sessions (six brands of think products in one session and six brands of feel products in another session). In the end, 313 participants completed the questionnaire on the six brands of think products, and 320 completed the questionnaire on the six brands of feel products.

Findings
– Multiple regression analysis revealed that Hipness/Vivacity, Success, Sincerity and Sophistication brand personality dimensions are significant predictors of purchase intention. In addition, Domesticity/Emotionality and Professionalism also explain purchase intention but with a negative weight. The results are also broken down into product categories. Compared with non-users of the brands, the users rate the brands higher in all the brand personality dimensions.

Practical implications
– This paper should prove useful to marketing practitioners to understand how Mexican customers perceive their brands and those of their competitors and, therefore, to understand what competitors of these brands can do to increase purchase intention.

Originality/value
– The results found regarding purchase intention are important, as they can be used to identify those personality brand dimensions that appear to be most important in explaining consumer preferences.
Conceptualising the influence of the cultural orientation of Latin Americans on consumers’ choice of US brands
Authors: Gaur Sanjaya S. , Bathula Hanoku , Diaz Carolina Valcarcel 
Published: July 2015

Purpose– The purpose of this study is to identify the main cultural factors that influence Latin American consumers’ intentions to purchase US brands. Although culture and cultural orientation have been well researched in international business and marketing literature, there is a lack of research on the relationship between consumers’ cultural orientation and their bias towards foreign and domestic products.Design/methodology/approach– The paper reviews the extant literature with a particular emphasis on the key constructs of consumer ethnocentrism, consumer xenocentrism, conspicuous consumption and consumers’ national characteristics. Based on this review, the authors propose a conceptual model showing the influence of cultural orientation on the selection of US brands in Latin America.Findings– The review of the literature shows that previous studies support the proposition of cultural orientation and preferences for foreign versus domestic products among Latin American consumers. Accordingly, in their conceptual framework, the authors posit that consumer ethnocentrism negatively influences the selection of US brands, while xenocentrism does the opposite. Conspicuous consumption is posited as moderating the influence of consumer xenocentrism on purchase intentions of the US brands. On the other hand, national characteristics of consumers in Latin America are posited as moderating the influence of both consumer ethnocentrism and consumer xenocentrism on the selection of US brands.Practical implications– The authors also present important theoretical and practical implications that contribute to the growing body of research on consumer acculturation and country of origin effects, providing a better interpretation of consumer behaviour in the context of international and domestic markets.Originality/value– This study fills a significant gap in the understanding of the impact of cultural orientation and conspicuous consumption on selection of US brands in Latin America. Its conceptual framework can provide the basis for future empirical studies and also improve understanding of emerging markets.
Critical characteristics for the implementation of mass-customized services
Authors: Vidor Gabriel , Medeiros Janine Fleith de , Fogliatto Flavio Sanson , Tseng Mitchel M. 
Published: July 2015

Purpose
– This paper aims to propose a method to determine which mass customization (MC) characteristics should be prioritized in mass-customized service design.

Design/methodology/approach
– Looking at manufacturing MC systems and conducting a literature review, it is not possible to observe a methodological step to define customized service design as the one we propose in this work. Results show a systematic classification of MC characteristics based on MC enablers and service enablers. These enablers are related by a quality function deployment (QFD) matrix and rewritten using a reverse QFD procedure.

Findings
– In the end, it was possible to determine which characteristics should be prioritized in mass-customized services.

Research limitations/implications
– Two case studies were performed: one with an electric power supplier and another one with a university.

Practical implications
– It shows that despite easy customization, organization is not always interest in service features customization. The explanation in these two cases is customization cost, which compared to the benefit does not seem advantageous for the organization.

Originality/value
– This paper creates a methodology to design a first phase in customized services in Latin American services and that is the original contribution.
Subsidiary strategy processes in Latin America
Authors: Ljung Anna , Pahlberg Cecilia 
Published: July 2015

Purpose– The purpose of this paper is to discuss how network relationships, with business as well as with non-business actors, affect each other and have an impact on strategy processes in subsidiaries in Latin America.Design/methodology/approach– A qualitative approach is used in which a new strategy in a European multinational company (MNC) is studied at the subsidiary level in Brazil and Argentina. The authors discuss why the strategic processes are so different within the same MNC. During 2009-2011, 50 interviews were conducted with respondents in Latin America and at headquarters.Findings– The results point to the importance of including relationships with both business and non-business actors to understand the subsidiary strategy processes. The authors suggest that such processes can be explained by interdependent relationships in a wider network context characterised by commitment and trust, leading to increased legitimacy among the actors involved.Practical implications– Managers need to invest in relationships not only with business counterparts but also with non-business actors, as they are interdependent and vital for the strategy development.Originality/value– Relationships between firms and actors such as governments and civil society are still under-researched, although they are essential, especially in emerging economies. The paper puts focus on network relationships in strategy research and contributes to the development of business network theory by extending the network to also include relationships with such non-business actors and relate it to strategy processes. There is also a contribution to research on corporate social responsibility activities with a specific focus on Latin America.
The effects of gender differences on the use of annotatable multimedia e-readers
Authors: Liu Yi-Fan , Hwang Wu-Yuin , Chen Sherry 
Published: July 2015

Purpose
– This paper aims to examine how gender differences influence students’ reactions to the use of the annotatable multimedia e-reader (AME). To reach this aim, we develop an AME where various annotation tools are provided to help students learn English in-class and after-class.

Design/methodology/approach
– An empirical study was conducted with 63 fifth-grade students from an elementary school. A pre-test and post-test were used to identify their prior knowledge and learning achievement, respectively. A questionnaire was applied to identify participants’ perceptions towards the AME.

Findings
– The results show that students’ post-test scores are significantly related to after-class behaviour, instead of in-class behaviour. Females prefer to use the text annotation and teachers’ voice, but it is voice annotation that is beneficial to improve their learning achievement. Conversely, males prefer to use the text-to-speech only, but it is text annotation that is helpful to improve their learning achievement. Additionally, the ease of use affects males’ intention to use the AME to learn English after-class while it has no effects on females.

Originality/value
– This study not only shows the importance of gender differences but also demonstrates the essence of after-class learning behaviour. More importantly, a framework is proposed to support designers to develop e-readers that can accommodate the preferences of females and males.

Published: July 2015

Purpose– The purpose of this study is to present a model for influential factors on customer loyalty in public libraries and its evaluation in public libraries of western Iran.Design/methodology/approach– This research is a correlation study and uses a questionnaire as a data gathering tool. The statistical population consists of all members of public libraries in western Iran. The final data analysis was carried out using 467 completed questionnaires and data were analysed using SPSS19 and AMOS19 software.Findings– The findings of this study showed that perceived value has the largest influence on customer loyalty with a factor of 0.451. The second most influential factor is customer satisfaction with a factor of 0.214. Three predictor variables are the effect of the services, controlling the provided information and library as a location, which had the highest influence on perceived value of libraries’ customers. The findings also showed that perceived value with meaningfulness level ofp< 0.001 and a value of 0.316 has the most influence on libraries’ customer satisfaction.Originality/value– Identifying and improving the influential factors on customer loyalty in public libraries can increase the customer return rate of these libraries. Public library managers of Iran, especially in western Iran, can use the findings of this study to improve the influential factors on customer loyalty in libraries under their care.

A cross-cultural comparison of concepts in computer science education
Authors: Zendler Andreas , McClung O. William , Klaudt Dieter 
Published: July 2015

Purpose– The development of a K-12 computer science curriculum based on constructivist principles needs to be informed by knowledge of content and process concepts that are central to the discipline of computer science. The paper aims to discuss this issue.Design/methodology/approach– Taking a cross-cultural approach and using an experimental design (a SPF-2•15×16 split-plot design), this study compares the combinations of content and process concepts identified as important in Germany with those considered relevant in the US context.Findings– First, the combinations of content and process concepts identified in the German context can be generalized to the US context. Second, it is possible to identify combinations of content and process concepts in the US context that are also important in the German context. Third, content and process concepts identified in the two contexts can be integrated to generate a broader perspective that is valid for both contexts.Practical implications– The results can be used for consolidating available curricular drafts for computer science as a teaching subject at school of the type available in many. The present findings are of great relevance for research-based approaches to the pre- and in-service education of computer science teachers. The methodological approach taken is important in efforts to consolidate curricular models of computer science education, as have been initiated by the Bologna process in Europe and by the organizations Association for Computing Machinery, Association for Information Systems, and Institute of Electrical and Electronic Engineers-Computer Society in the USA.Originality/value– Results show that competence areas of central concepts identified in the two contexts can be integrated to generate a broader perspective that is valid for both contexts.
“The tablet is on the table!” The need for a teachers’ self-hetero-eco technological formation program
Authors: Freire Maximina Maria 
Published: July 2015

Purpose– The Federal Government has begun distributing tablets to teachers in public schools in Brazil. However, no preparation was provided to guide professionals on how to use them for pedagogical purposes. As a result, teachers have been carrying tablets around or leaving them alone on their classroom tables. Considering this situation, the purpose of this paper is to discuss the possibility of adopting a ternary conception of formation processes – the self-hetero-eco formation process – to help teachers learn how to use tablets for educational purposes; and on the potential of such a process to congregated teachers in the joint creation and maintenance of a Didactic Digital Material/App Data Bank.Design/methodology/approach– Theoretically, this paper is grounded on complexity principles (Morin, 2008, 2010), and especially on the studies made by Moraes (2007), Freire (2009) and Freire and Leffa (2013).Findings– The movement of perceiving each teacher as responsible for his/her formation (personalization), interacting with others to expand possibilities, co-constructing knowledge to reach co-formation (socialization), and interacting with the environment with/from which s/he learns (ecoligization) will reveal the self-hetero-eco technological formation process which may help teachers create steady links amongst themselves at school and resolve many difficult situations such as the need to overcome the lack of technological skills to use tablets. Besides that, the idea of joining teachers together and jointly creating and maintaining a Didactic Digital Material/App Data Bank may not only impact on the use of the tablet itself but also on interpersonal relationships, intensifying respect, companionship and friendship, among other important ties that help bind people together.Originality/value– This paper presents an innovative formation concept which is not based on time development, but which is based on the agents involved in the process and in the environment where the formation takes place. This concept is based on complexity and seems to be more attuned to the features of the contemporary world.
Future vision
Authors: Rogerson Simon 
Published: July 2015

Purpose
– The purpose of this paper is to review the world of information and communications technology (ICT) from its early days to the near future. The aim is to consider how successfully academia, industry and government have worked together in delivering ethically acceptable ICT which is accessible to those who might benefit from such advances. The paper concludes with suggestions of a fresh approach for the future.

Design/methodology/approach
– The paper draws upon evidence from the history of computers, funded research projects, professional bodies in the field, the ETHICOMP conference series and reported ICT disasters. The author uses his experience as both an ICT practitioner and an academic in the ICT ethics field to synthesise the evidence so providing a foundation on which to build an outline global action plan.

Findings
– The paper lays out the findings that there has been much detailed observation and analysis of the ethical challenges surrounding ICT but the transformation of this into widespread practical positive action remains elusive. It explores why progress has been difficult.

Originality/value
– This review of the interconnecting landscapes of practical ICT, funded research and the ICT ethics community is new. The attempt to demonstrate what progress has been made and to identify the underlying factors which influence progress are valuable to future generations working in this area. The concluding suggestions for action offer a starting point for entering the next phase of ICT ethics.
