ABSTRACTAncient DNA studies have revolutionised the study of extinct species and populations, providing insights on phylogeny, phylogeography, admixture and demographic history. However, inferences on behaviour and sociality have been far less frequent. Here, we investigate the complete mitochondrial genomes of extinct Late Pleistocene cave bears and middle Holocene brown bears that each inhabited multiple geographically proximate caves in northern Spain. In cave bears, we find that, although most caves were occupied simultaneously, each cave almost exclusively contains a unique lineage of closely related haplotypes. This remarkable pattern suggests extreme fidelity to their birth site in cave bears, best described as homing behaviour, and that cave bears formed stable maternal social groups at least for hibernation. In contrast, brown bears do not show any strong association of mitochondrial lineage and cave, suggesting that these two closely related species differed in aspects of their behaviour and sociality. This difference is likely to have contributed to cave bear extinction, which occurred at a time in which competition for caves between bears and humans was likely intense and the ability to rapidly colonise new hibernation sites would have been crucial for the survival of a species so dependent on caves for hibernation as cave bears. Our study demonstrates the potential of ancient DNA to uncover patterns of behaviour and sociality in ancient species and populations, even those that went extinct many tens of thousands of years ago.
Rapid dynamics of cell-shape recovery in response to local deformations
Authors: Haase Kristina , Shendruk Tyler N. , Pelling Andrew E. 
Published: May 2016

ABSTRACTIt is vital that cells respond rapidly to mechanical cues within their microenvironment through changes in cell shape and volume, which rely upon the mechanical properties of cells’ highly interconnected cytoskeletal networks and intracellular fluid redistributions. While previous research has largely investigated deformation mechanics, we now focus on the immediate cell-shape recovery response following mechanical perturbation by inducing large, local, and reproducible cellular deformations using AFM. By continuous imaging within the plane of deformation, we characterize the membrane and cortical response of HeLa cells to unloading, and model the recovery via overdamped viscoelastic dynamics. Importantly, the majority (90%) of HeLa cells recover their cell shape in < 1s. Despite actin remodelling on this time scale, we show that cell recovery time is not affected by load duration nor magnitude. To further explore this rapid recovery response, we expose cells to cytoskeletal destabilizers and osmotic shock conditions, which exposes the interplay between actin and osmotic pressure. We show that the rapid dynamics of recovery depend crucially on intracellular pressure, and provide strong evidence that cortical actin is the key regulator in the cell-shape recovery processes, in both cancerous and non-cancerous epithelial cells.
Applying threshold concepts to finance education
Authors: Hoadley Susan , Wood Leigh N , Tickle Leonie , Kyng Tim 
Published: May 2016

Purpose– The purpose of this paper is to investigate and identify threshold concepts that are the essential conceptual content of finance programmes.Design/methodology/approach– Conducted in three stages with finance academics and students, the study uses threshold concepts as both a theoretical framework and a research methodology.Findings– The study identifies ten threshold concepts in finance that are clearly endorsed by finance academics. However, the extent to which students are explicitly aware of the threshold concepts in finance is limited.Research limitations/implications– As well as informing further research into the design and delivery of finance programmes, the findings of the study inform the use of threshold concepts as a theoretical framework and a research methodology. The study does not explore the bounded, discursive, reconstitutive and liminal aspects of threshold concepts. Implications include the lack of recognition of more modern concepts in finance, and the need for input from industry and related disciplines.Practical implications– The threshold concepts in finance provide the starting point for finance educators in the design and delivery of finance programmes. In particular, the threshold concepts in finance need to be made more explicit to students.Social implications– Using the threshold concepts in finance as well as the other findings of this study to inform to finance curriculum design and delivery is likely to achieve better quality educational outcomes for finance students as well as better prepare them for professional finance roles.Originality/value– The finance curriculum is under researched and for the first time this study identifies the threshold concepts in finance to inform the design of finance programmes.
Threshold concepts in business school curriculum – a pedagogy for public trust
Authors: Bajada Christopher , Jarvis Walter , Trayler Rowan , Bui Anh Tuan 
Published: May 2016

Purpose– The purpose of this paper is to explore some of the implications for curriculum design by operationalizing threshold concepts and capabilities (TCC) in subject delivery. The motivation for undertaking this exploration is directly related to addressing public concerns for the business school curriculum.Design/methodology/approach– Apost factoanalysis of a compulsory subject in finance that is part of an Australian business degree and the impact on a subsequent finance subject.Findings– Customary approaches to granting part-marks in assessing students, (fractionalising) understanding of content can mean students pass subjects without grasping foundational concepts (threshold concepts) and are therefore not fully prepared for subsequent subjects.Research limitations/implications– Students passing subjects through fractionalization are poorly equipped to undertake deeper explorations in related subjects. If replicated across whole degree programs students may graduate not possessing the attributes claimed for them through their qualification. The implications for undermining public trust and confidence in qualifications are profound and disturbing.Practical implications– The literature has exposed risks associated with operationalizing threshold through assessments. This highlights a risk to public trust in qualifications.Originality/value– Operationalizing threshold concepts is an underexplored field in curriculum theory. The importance of operationalizing customary approaches to assessments through fractionalising marks goes to the legitimacy and integrity of qualifications granted by higher education. Operationalizing assessments for TCC presents profound, inescapable and essential challenges to the legitimacy of award granting institutions.
Threshold concepts and pedagogic representation
Authors: Meyer Jan H.F. 
Published: May 2016

Purpose
– The purpose of this paper is to present a brief exposure to the development of the threshold concepts framework (TCF), the intention being to illuminate for interested readers a broader landscape of research activity than that perhaps conveyed by the individual contributions to this special edition.

Design/methodology/approach
– There is first an account of how the notion of a “threshold concept” was presented by Meyer and Land in their seminal 2003 paper, and a clarification of some terminology used by them at that time to describe the (confusing for some) “characteristics” of such a concept. A discursive account, with examples, follows on how analyses for, and of, threshold concepts might proceed, and how findings might provoke a reappraisal of associated learning and teaching practices. Towards this end a contemporary pedagogical perspective is introduced based on the construct of integrated threshold concept knowledge (ITCK) as proposed by Meyer and Timmermans (2016). Reference to a detailed case study illustrates the practical dynamics of generating ITCK; specifically in the context of a third-year engineering course embedding the threshold of “critical flow”. Activities and processes, transferable to other discipline contexts, are described that yield particular elements of ITCK (different constituent “types of knowledge”) in relation, in this case, to “critical flow”. A final consideration is the “representation” of “critical flow” for pedagogical purposes in the form of a metacognitive activity for learning and formative assessment purposes that is, again, adaptable to other discipline contexts.

Findings
– There are no specific findings in this paper as its purpose is to provide a condensed review of the development of the TCF.

Originality/value
– This value of this paper is that it provides a contemporary expert exposure to the development of the TCF by the originator of the notion of a threshold concept.
ACTVOD-futures workshop – a generic structure for a one-day futures workshop
Authors: Lauttamäki Ville 
Published: May 2016

Purpose
This paper introduces a generic structure for a futures workshop, developed especially to be used in brief practically oriented foresight projects. Based on experiences of tens of dozens of workshops where this method has been used, this paper aims to inform and educate practitioners of futures studies on the method and discuss its characteristics.

Design/methodology/approach
The design of the ACTVOD workshop method was influenced by the need to have a futures workshop design that would encourage creativity and allow for the hosting of a futures workshop in a rather short amount of time. ACTVOD takes advantage from several theoretical insights and methods within futures studies. It combines elements from heuristic problem-solving, scenario workshops (focus on finding action plans towards desired future) and soft systems methodology.

Findings
ACTVOD is a rather easy and time-efficient way of producing and collecting good-quality insights on the future and bringing those insights to a practical level. Major challenges using it relate to the transition between workshop stages and on reporting, which relies heavily on participants' activity.

Originality/value
This is the first time the characteristics of the ACTVOD workshop method are thoroughly introduced in an academic journal. Learning of the method would be useful for practitioners of participatory futures studies methods, especially those who are frequently invited to facilitate short workshops for varying audiences.
The influence of trust and perceived playfulness on the relationship commitment of hospitality online social network-moderating effects of gender
Authors: Li Chi-Hua , Chang Chun-Ming 
Published: May 2016

PurposeFrom the commitment–trust theory angle, this study aims to understand why members of social network sites (SNSs) are willing to build a relationship commitment with hospitality SNSs, engage in online word-of-mouth (WOM) and show a willingness to repurchase. This paper proposes a model to express the relationship commitment and gender as a moderator in the relationship.Design/methodology/approachThe interviews of a formal survey were selected by a purposive sampling method, and an online questionnaire survey was conducted in Taiwan. This study used the partial least square method to conduct structural equation modeling analysis.FindingsThe findings suggest that trust and perceived playfulness of the hospitality community have positive influences on relationship commitment, and also that the relationship commitment has a positive influence on online WOM and willingness to repurchase. This analysis provides strong support for the view that gender exerts a significant moderating role on our model relationships.Practical implicationsSNSs aspiring to stand out in the highly competitive internet environment must cultivate consumers’ trust and relationship commitment, and develop strategies to retain community members, as well as strengthen the safeguard personal information and the playfulness of activities. SNSs that launch relationship marketing activities should encourage community members to spread positive WOM through various activities.Originality/valueThis study combined the commitment–trust theory and technology acceptance model. It aimed to develop a theory-based model of relationship commitment in the hospitality SNSs’ context. Both trust and perceived playfulness are positively related to commitment; they are essential and important elements of successful hospitality SNSs. The gender difference plays a vital role in determining individuals’ behavior intention in the hospitality SNSs, as females and males have different decision-making processes.

Authors: Huang Jun , Li Weiwen , Qiu Canhua , Yim Frederick Hong-kit , Wan Junbao 
Published: May 2016

PurposeThe purpose of this paper is to draw on the theory of servant leadership to examine the influence of chief executive officer (CEO) servant leadership on firm performance in the hospitality industry. It examined the mediating role of the service climate and the moderating role of competitive intensity in the relationship between CEO servant leadership and firm performance.Design/methodology/approachMultiple regression was used to analyze multi-wave, multi-source data from 92 hotels in China. A moderated path analysis was used to test the moderating effects.FindingsCEO servant leadership positively influenced firm performance via the service climate in the hospitality industry. Competitive intensity strengthened the direct effect of the service climate on firm performance, and the indirect effect of CEO servant leadership on firm performance via service climate.Research limitations/implicationsThe findings offer managerial insights into CEO succession, service management and human resource management.Originality/valueThis is one of the first studies to investigate how and when CEO servant leadership might shape firm outcomes in the hospitality industry. Theoretically, the findings enrich our understanding of how CEO leadership might shape firm-level outcomes.
Attitudinal similarities and differences of hotel frontline occupations
Authors: Robinson Richard N.S. , Kralj Anna , Solnet David J. , Goh Edmund , Callan Victor J. 
Published: May 2016

Purpose
The purpose of this study is to identify across a number of workplace variables the similarities and differences in attitudes between three key frontline hotel worker groups: housekeepers, front office employees and food and beverage front-of-house staff.

Design/methodology/approach
A qualitative study was conducted using 25 semi-structured interviews with frontline workers employed in full-service hotels across Eastern Australia. Analysis was augmented through the Leximancer® software package to develop relational themes in the aggregation and disaggregation of the occupations.

Findings
Although work/life balance was a common theme across the three occupations, several distinct attitudinal differences emerged, in particular regarding perceptions of one occupational group towards another.

Practical implications
This study highlights the importance of hotel managers being cognisant of occupational differences and collecting data capable of assisting in the identification of these differences. Several practitioner relevant recommendations are made.

Originality/value
This exploratory study challenges assumptions regarding a “pan-industrial” hospitality occupational community and applies an emerging qualitative software package to highlight occupational differences and relational perceptions.
Does leader-member exchange enhance performance in the hospitality industry?
Authors: Wang Chung-Jen 
Published: May 2016

PurposeThis paper aims to integrate leader–member exchange (LMX), creativity and performance research and to develop a model to investigate the relationships among LMX, task motivation, creativity and performance in the hospitality industry.Design/methodology/approachStructural equation modeling (SEM) with bootstrap estimation was conducted with a sample of 312 leader–employee dyadic data from international tourist hotels in Taiwan.FindingsThe results revealed that LMX positively affected performance and creativity. Most important of all, task motivation was found to mediate the relationship between LMX and creativity, while both task motivation and creativity were found to mediate the relationship between LMX and performance.Research limitations/implicationsWith efforts to combine research variables into a unified theoretical model, this study is the first in the field of hospitality research which explores the two-path mediating effects of these relationships in an integrated SEM framework. More specifically, this study provides a synthesized perspective with bootstrap analyses to broaden hotel research with regard to LMX and examine its influences on employees’ creativity and performance.Practical implicationsThe results of this study suggest that human resource departments in hotel companies should provide training programs for supervisors and employees to enhance their reciprocal relationships, and establish reward mechanisms to encourage the development of more creative services at work.Originality/valueThis study added to the literature with its use of a non-Western sample, and extended the prior research in the context of the hospitality industry. Overall, the conclusions provide empirical evidence in an integrated model that task motivation can strengthen the influence of LMX on creativity and can also nourish the influence of creativity on employee performance.

A serious game-based solution to prevent bullying
Authors: Raminhos Cátia , Cláudio Ana Paula , Carmo Maria Beatriz , Gaspar Augusta , Carvalhosa Susana , Candeias Maria de Jesus 
Published: May 2016

Purpose
The purpose of this paper is to present a Serious Game with the main purpose of inducing attitude changes as a way to prevent bullying, in a target audience of young people between 10 and 12 years old.

Design/methodology/approach
The rationale for prevention is: first, to help victims of these aggressive episodes to acquire or improve competencies in avoiding or dealing with future real bullying situations; and second, to promote empathy toward the victims in bystanders. A back office application complements the game, providing substantial assistance to psychologists while using the game with patients in therapy or in research work.

Findings
Both components, the game and the back office, were evaluated with volunteers. The user study leads the authors to the conclusion that the current version of the game holds good potential in bullying prevention: the young people that played the game in a continuous time span, at the end of this testing process, have expressed improvements in their bullying prevention strategies. The back office application, a distinctive feature of the solution when compared to other similar bullying prevention solutions, was positively assessed by the psychologists who tested it.

Originality/value
The game deals with strong social features, such as number of friends and invitations to social events (e.g. a birthday party), to which young people give much importance. Additionally, it offers a variability of scenarios and consequences of actions, taking into account the user’s performance in the game. The main factors that makes the presented solution stand out in comparison with other similar bullying prevention solutions are mainly the following: It includes a back office application to assist therapists with data management features; the role of the player in the game can be chosen according to his own profile; it is possible to play even outside a therapy session (e.g. at home); and it is a portable solution.

Authors: Mousannif Hajar , Sabah Hasna , Douiji Yasmina , Oulad Sayad Younes 
Published: May 2016

PurposeThis paper aims to provide a roadmap for organizations to build big data projects and reap the most rewards out of their data. It covers all aspects of big data project implementation, from data collection to final project evaluation.Design/methodology/approachIn each stage of the proposed roadmap, we introduce different sets of information and communications technology platforms and tools to assist IT professionals and managers in gaining a comprehensive understanding of the methods and technologies involved and in making the best use of them. The authors also complete the picture by illustrating the process through different real-world big data projects implementations.FindingsBy adopting the proposed roadmap, companies and organizations willing to establish an effective and rewarding big data solution can tackle all implementation challenges in each stage of their big data project setup: from strategy elaboration to final project evaluation. Their expectations of privacy and security are also baked, in advance, into the big data project design.Originality/valueWhile technologies to build and run big data projects have started to mature and proliferate over the last couple of years, exploiting all potentials of big data is still at a relatively early stage. The value of this paper consists in providing a clear and systematic methodology to move businesses and organizations from an opinion-operated era where humans’ skills are a necessity to a data-driven and smart era where big data analytics plays a major role in discovering unexpected insights in the oceans of data routinely generated or collected.
