Purpose Expert Cloud as a new class of cloud systems enables its users to request and share the skill, knowledge and expertise of people by employing internet infrastructures and cloud concepts. Since offering the most appropriate expertise to the customer is one of the clear objectives in Expert Cloud, colleague recommendation is a necessary part of it. So, the purpose of this paper is to develop a colleague recommender system for the Expert Cloud using features matrices of colleagues. Design/methodology/approach The new method is described in two phases. In the first phase, all possible colleagues of the user are found through the filtering mechanism and next features of the user and possible colleagues are calculated and collected in matrices. Six potential features of colleagues including reputation, expertise, trust, agility, cost and field of study were proposed. In the second phase, the final score is calculated for every possible colleague and then top-k colleagues are extracted among users. The survey was conducted using a simulation in MATLAB Software. Data were collected from Expert Cloud website. The method was tested using evaluating metrics such as precision, accuracy, incorrect recommendation and runtime. Findings The results of this study indicate that considering more features of colleagues has a positive impact on increasing the precision and accuracy of recommending new colleagues. Also, the proposed method has a better result in reducing incorrect recommendation. Originality/value In this paper, the colleague recommendation issue in the Expert Cloud is pointed out and the solution approach is applied into the Expert Cloud website.

Purpose – Expert Cloud as a new class of Cloud systems provides the knowledge and skills of human resources (HRs) as a service using Cloud concepts. Task scheduling in the Expert Cloud is a vital part that assigns tasks to suitable resources for execution. The purpose of this paper is to propose a method based on genetic algorithm to consider the priority of arriving tasks and the heterogeneity of HRs. Also, to simulate a real world situation, the authors consider the human-based features of resources like trust, reputation and etc. Design/methodology/approach – As it is NP-Complete to schedule tasks to obtain the minimum makespan and the success of genetic algorithm in optimization and NP-Complete problems, the authors used a genetic algorithm to schedule the tasks on HRs in the Expert Cloud. In this method, chromosome or candidate solutions are represented by a vector; fitness function is calculated based on several factors; one point cross-over and swap mutation are also used. Findings – The obtained results demonstrated the efficiency of the proposed algorithm in terms of time complexity, task fail rate and HRs utilization. Originality/value – In this paper the task scheduling issue in the Expert Cloud and improving pervious algorithm are pointed out and the approach to resolve the problem is applied into a practical example.

Purpose This paper aims to trace the tectonic effects of openings as Heideggerian “built-things”. Design/methodology/approach This study has been organized in two phases. The first phase attempts to set up the theoretical framework through exploring the links between Heidegger’s notion of “built-thing” and contemporary tectonic discourses on dialectics between the values of matheme (construction, technology) and poetics (representation, meaning) to identify the key indicators in tectonic effects of openings. Accordingly, as the term “tectonic effects” is concerned with feelings and emotions that tectonics may evoke in people, the author searches for the indicators based on the poetic aspects of tectonic values and applies them within the phenomenological method implemented in the second phase of the research to explore the indicators in the designated case of the “Çavuşoğlu house”. Findings The results of this study indicate the significance of ontological nexus between tectonics as “poetic revealing” and the ability of the “built-thing” to generate tectonic effects within the embodied experience of dwellers. In fact, an opening can generate ontological tectonic effects in space only if it is brought about through a truthful build-dwell process which responds in a poetic way to the daily-life needs of the dwellers. The tangible examples of this fact are evident in the openings of the Çavuşoğlu house. Originality/value The theory of tectonics of openings as a separate “built-thing”, which is put forward in the present study, is a subject that has not been sufficiently studied so far and has the potential to be developed through further research. In light of this, the theoretical results of this study can contribute to tectonic thinking during the design process.

Purpose The purpose of this study is to investigate the level of understanding of Muslim students about Istihalah. It compares the understanding of students of various departments about Istihalah and changes in their knowledge after a workshop. Design/methodology/approach The study is conducted in two phases. In the first phase, a comparison is made between students of three departments: Islamic studies, business studies and food sciences. These departments were selected using purposive sampling. In the second phase, students with a lack of awareness about Istihalah were given a one-day training workshop on the concept of Istihalah. Data were collected through a personally administrated questionnaire. Findings The results of the first phase revealed that students from business studies and food sciences were not familiar with the concept and application of Istihalah, whereas students from Islamic studies were well-aware of it. The findings of the second phase revealed that after the provision of training (workshop), students were at par with the students of Islamic studies. All the students were further willing to know about Istihalah and its implications in their personal and professional lives. Originality/value The main contribution of this study is to highlight the area where information about Islamic concepts should be disseminated and applied.

Purpose – The purpose of this paper is to describe the development and evaluation of CanSpeak which is an open-source speech interface for users with dysarthria of speech. The interface can be customized by each user to map a small number of words they can speak clearly to commands in the computer system, thereby adding a new modality to their interaction. Design/methodology/approach – The interface was developed in two phases: in the first phase, the authors used participatory design to engage the users and their community in the customization of the system, and in the second phase, we used a more focussed co-design methodology during which a user of the system became a co-designer by directly making new design decisions about the system. Findings – The study showed that it is important to include assistive technology users and their community in the design and customization of technology. Participation led to increased engagement, adoption and also provided new ideas that were rooted in the experience of the user. Originality/value – The co-design phase of the project provided an opportunity for the researchers to work closely with a user of their system and include her in design decisions. The study showed that by employing co-design new insights into the design domain can be revealed and incorporated into the design that might not be revealed otherwise.

Purpose – The purpose of this paper is to identify the elements of a LinkedIn profile that hiring professionals focus on most, and then examine LinkedIn profiles in terms of these identified elements across different industries. Design/methodology/approach – The methodology was comprised of two phases. In the first phase, researchers interviewed hiring professionals to determine their usage of LinkedIn. In the second phase, LinkedIn group member profiles from three industries – HR, sales/marketing and industrial/organizational (I/O) psychology – were compared on the 21 variables identified in Phase 1 (n=288). Findings – χ2 and ANOVA tests showed significant differences with respect to ten of the LinkedIn variables in how people presented themselves across the three groups. There were also several gender differences found. Research limitations/implications – A general limitation was the use of a qualitative research approach. A limitation of Phase 1 was that only a small sample of New York City-based hiring professionals was interviewed. Perhaps a wider, more diverse sample would have yielded different variables. In terms of Phase 2, it is possible that just utilizing the second connections of the researchers limited the generalizability of findings. Practical implications – User unwillingness to fully complete the LinkedIn profile suggests that it may not have replaced the traditional resume yet. Sales/marketing professionals were more likely than HR and I/O psychology professionals to complete multiple aspects of a LinkedIn profile. Women were also less likely than men to provide personal information on their profiles. Originality/value – Most of the empirical research on social networking sites has focussed on Facebook, a non-professional site. This is, from the knowledge, the first study that systematically examined the manner in which people present themselves on LinkedIn – the most popular professional site used by applicants and recruiters worldwide.

Purpose The purpose of this paper is to analyze how family ownership influences the strength of the board’s monitoring function in companies’ decisions regarding the assurance of sustainability reports. Design/methodology/approach The international sample consists of 536 companies operating in more stakeholder-oriented countries during the period 2007-2014. The paper proposes alternative logit models of analysis using the random-effects estimator. Findings The results provide evidence that a firm’s sustainability assurance and its choice of accounting professionals as higher quality assurers are positively associated with board size and independence. The main result is the positive impact of family businesses on these assurance issues. The paper evidences the greater orientation toward sustainability issues of family businesses. Furthermore, it verifies the greater impact of board size on family firms’ assurance demand. Originality/value This study sheds some light on the unexplored topic of sustainability assurance in family firms. One of the differentiating aspects with respect to previous studies is the consideration of the moderating factor of family property. This study also contributes to the understanding of family firms’ demand for assurance and its practitioners, and the literature’s focus on its determinants.

Purpose The purpose of this paper is to examine the motivations of social entrepreneurs. It explores the case of the Gathering in Ireland in 2013, when against a backdrop of recession, the national Government encouraged individuals and communities to organize events and invite the Diaspora to visit Ireland as a way of helping the country to revitalize. Some 5,000 events took place across the country during the year, and this paper examines this in the context of social entrepreneurship. Three research questions are posed: Who were these tourism and social entrepreneurs who organized events as a result of the Gathering? What motivated them to engage in these activities? Will this social entrepreneurship activity be maintained beyond 2013 and how has it been impacted by the Gathering? Design/methodology/approach The empirical research was conducted in two counties in Ireland, Co. Kerry and Co. Westmeath. The research tools used were key informant interviews, a survey of event organizers and focus groups. Findings Key findings show that the Gathering has resulted in the emergence of new social entrepreneurs, but it has also had a positive impact on those who had run their events before, as it made them be more strategic in the way they planned and ran their event and also resulted in them thinking about these events in terms of tourists rather than just the local community. They also developed new skills which will aid their future development. It is clear that social entrepreneurs can play a fundamental role in the development of tourism destinations, and this is an important topic for researchers in tourism to be concerned about. Originality/value The originality of this paper lies in the fact that it addresses the issue of motivation of social entrepreneurs and challenges us to think more about how these types of entrepreneurs identify the problem that they will address. Furthermore, this case shows that the motivation for such action can be prompted by a national strategy, rather than as the literature heretofore represented it as an innate motivation that materialized and developed within particular individuals.

Purpose Organizational leaders and human resource professionals affirm that to have (and keep) an effective workforce, understanding one’s employees is critical. Thus, understanding the differences between employees of different age groups is important. Simultaneously, studies have demonstrated the significant positive impact appreciation has on the functioning of organizations. When team members feel truly valued, numerous positive benefits result, including lower staff turnover, less absenteeism, higher customer ratings and greater profitability. Design/methodology/approach Because individuals prefer to be shown appreciation in different ways and prior research has shown some age differences, this study examined how appreciation preferences differ across seven employee age groups. Over 190,000 individuals completed an online assessment based on the five languages of appreciation, which identifies employees’ preferred ways of receiving appreciation. The respondents were separated into seven age groups, from 19 years old and younger to 70 years old and above. Findings The results of an analysis of variance found that there were significant differences across groups. Although the patterns of preferences were largely the same across many groups, post hoc analyses found both the youngest and oldest age groups differed from employees in their 30s with regards to their desire for quality time. Additionally, older employees were extremely low in their desire for tangible gifts. Originality/value As the proportion of employees shifts from older to younger groups of employees, these results raise important implications for organizations’ approaches regarding how appreciation and other motivators should be adjusted for different groups of employees.

Purpose This paper aims to discuss additive manufacturing (AM) in the context of applications for musical instruments. It examines the main AM technologies used in musical instruments, goes through a history of musical applications of AM and raises the questions about the application of AM to create completely new wind instruments that would be impossible to produce with conventional manufacturing. Design/methodology/approach A literature research is presented which covers a historical application of AM to musical instruments and hypothesizes on some potential new applications. Findings AM has found extensive application to create conventional musical instruments with unique aesthetics designs. It’s true potential to create entirely new sounds, however, remains largely untapped. Research limitations/implications More research is needed to truly assess the potential of additive manufacturing to create entirely new sounds for musical instrument. Practical implications The application of AM in music could herald an entirely new class of musical instruments with unique sounds. Originality/value This study highlights musical instruments as an unusual application of AM. It highlights the potential of AM to create entirely new sounds, which could create a whole new class of musical instruments.
