Volunteer-based organizations are dependent on volunteers to meet the goals of the organization. Identifying and training volunteers as leaders of the organization is one way to increase positive social change in their community. However, there is limited literature investigating the outcomes of providing leadership training to volunteers. This case study determined participants’ perceptions of a volunteer leadership training experience compared to observations of the actual leadership training. A focus group revealed three themes that were both supported and refuted by observations of the training: (a) the need for refreshers and follow-up trainings, a disconnect between understanding leadership concepts and applying them in the volunteer scenario, and the transfer of for-profit skills and experience to the non-profit setting.

Librarians and information professionals increasingly need to deal with copyright issues in their work, however evidence suggests that they can lack confidence and often refer queries to a dedicated copyright specialist. The purpose of this paper is to explore the professional experiences of copyright of a group of academic librarians in the UK, with a view to devising appropriate copyright education strategies.

The research was conducted using phenomenography, which is a qualitative approach from education. Data were collected though group interviews to explore the variation of experience. Four categories of description were devised which are placed in an outcome space.

There were four qualitatively distinct ways that librarians experience copyright in their professional lives, including viewing it as a problem, as complicated, as a known entity and as an opportunity. The variations in experience relate to a variety of factors such as the librarians’ role, ideology, level of experience, context and with whom they might be dealing.

This is the first study of this nature, building on quantitative findings from a multinational survey. It concludes that librarians need to be taught about copyright in a way that acknowledges and addresses the challenges so that they can view it as empowering and as part of wider information literacy initiatives.

Non-profit and volunteer-based organizations are tasked with meeting the needs of their communities with limited resources. Today, more than ever, these organizations are stretched to their limits increasing the workload for paid staff. Training volunteers to lead the volunteer efforts is one way to spread the workload throughout the organization. Although there are guidelines for leadership development in for-profit organizations, there is limited literature pertaining to specific competencies and skills volunteer leaders in non- profit and volunteer-based organizations should possess. This study, employing Delphi methodology, was conducted with volunteer directors in the community to identify leadership competencies for volunteer leaders. At the conclusion of three rounds of iteration, 42 competencies were identified.

The purpose of this paper is to present findings from a multinational survey on copyright literacy of specialists from libraries and other cultural institutions.

This paper is based on a multinational survey of copyright literacy competencies of Library and Information Science (LIS) professionals and those who work in the cultural heritage sector (archives and museums), conducted in 13 countries, namely Bulgaria (BG), Croatia (CR), Finland (FI), France (FR), Hungary (HU), Lithuania (LT), Mexico (MX), Norway (NO), Portugal (PT), Romania (RO), Turkey (TR), UK and USA in the period July 2013-March 2015. An online survey instrument was developed in order to collect data from professionals regarding their familiarity with, knowledge and awareness of, and opinions on copyright-related issues.

Findings of this study highlight gaps in existing knowledge of copyright, and information about the level of copyright literacy of LIS and cultural sector professionals. Also attitudes toward copyright learning content in academic education and continuing professional development training programs are investigated.

This study aimed to address a gap in the literature by encompassing specialists from the cultural institutions in an international comparative context. The paper offers guidance for further understanding of copyright in a wider framework of digital and information literacy; and for the implementation of copyright policy, and the establishment of copyright advisor positions in cultural institutions. The recommendations support a revision of academic and continuing education programs learning curriculum and methods.

The purpose of this study is to investigate benefits tourist seek when visiting a nature-based tourism destination to develop a benefit segmentation framework.

The study used quantitative research methods, with 400 self-administered survey administered to a sample of 400 tourists visiting the Kruger, Panorama, and Lowveld areas in Mpumalanga.

Cluster analysis produced two benefit segments. Binary logistic regression benefits that emerged from the cluster analysis were statistically significant predictors of the attractions tourists visited and the activities in which they participated during their stays in Mpumalanga. Factor-cluster analysis and binary logistic regression results were used to develop a benefit segmentation framework as a marketing planning tool.

The study was only based on Mpumalanga Province and therefore, the results cannot be generalised. The study was conducted over one season, the Easter period

The proposed benefit segmentation framework provides a tool that destination management organisations can use to plan effectively for marketing.

Effective marketing may lead to increased tourism growth which can have a multiplier effect on the destination.

This article is based on a master’s study conducted in Mpumalanga and results are presented on this paper.

Wheel‐terrain interaction has hardly been taken into consideration in the process of conventional mobile robot design, but its importance has been reflected increasingly towards these categories of mobile robots in rough sandy terrain or obstacle‐dense ground, as the first performance index in this situation is the trafficability of robot whose propulsion is uniquely generated by wheel‐terrain interaction. Consequently, it is valuable to find an optimized design method when the terrain and robot itself are regarded simultaneously. The purpose of this paper is to present a novel and reasonable design approach to mobile robot in sandy terrain.

Leading to some conflicted performance indices of robot, terramechanics describes the non‐linear characteristics in wheel‐terrain interaction mathematically, therefore, trade‐offs must be implemented to get a proper solution by multi‐objective optimization (MOO). In this paper, a five‐wheeled drive and five‐wheeled steering (5WD5WS) reconfigurable mobile robot is taken as demonstration with taxonomy of total‐symmetrical, partial‐symmetrical and asymmetrical prototypes. After function modeling, the MOO is carried out via iSIGHT‐FD using NCGA (Neighborhood Cultivation Genetic Algorithm) to minimize the mass, wheel resistance and maximize the static stability simultaneously.

After MOO, a compact and light weighted asymmetrical prototype is obtained with better trafficability, and other prototypes can produce diversified configurations to meet specific requirements. Significantly reduced masses (about 17 kg) enhance the grade‐ability when robot is in rough terrain. Performed real‐world experiments have also verified these prototypes.

The paper presents a new design approach for a mobile robot which focuses on both robot and terrain simultaneously with respect to conflicted factors. To unveil the insight relation of these factors, MOO is an effective tool to get a trade‐offs prototype.

The purpose of this paper is to assess the prevalence and nature of presentation of unipolar depression in individuals with Down syndrome (DS).

The PRISMA (2009) checklist for systematic review was followed where possible.

Eight studies were included in the qualitative synthesis from a total of 634 records identified. The quality of the studies was then assessed: the studies all scored either 5 or 6 out of 6. The incidence of depression ranged between studies from 5 to 13 per cent. It was found that depression is more common in DS than the general intellectual disability population; this on a background of mental ill health of all causes being less common in DS. It was suggested that, excluding organic disorders, depression is the most common psychiatric problem in DS. In terms of the nature of depression, the evidence was less clear. Various “vegetative” and biological symptoms were observed, with no fixed pattern. There was evidence for withdrawal symptoms and psychosis.

The small number of studies included in this review, and their heterogeneity, highlights the need for further original research in this field.

An increased awareness of the frequency of depression in individuals with DS will aid in a timely diagnosis, therefore reduce psychiatric morbidity. Clinicians should be aware of the varied presentation, with no clear clinical picture, in order to maintain a high index of suspicion in an individual presenting with “atypical” symptoms.

This review has provided preliminary evidence that depression may be the most commonly experienced psychiatric disorder in DS.

Previous studies have found that abusive supervision undermines employees' work motivation and attitudes, namely work engagement and job satisfaction. However, less is known about the mechanisms by which abusive supervision negatively relates to employees' work engagement and job satisfaction. Drawing on conservation of resources theory, this study examines employee silence as a mediating mechanism linking abusive supervision to employees' work engagement and job satisfaction.

Survey data were collected from a sample of 233 full-time employees of a large hotel service company in Taiwan. Structural equation modeling analyses were conducted to test the hypotheses.

The results showed that abusive supervision has a positive association with employee silence. Moreover, the results showed that employee silence mediates the negative associations of abusive supervision with employees' work engagement and job satisfaction.

The results suggest that organizational managers should provide supervisors with leadership interventions to prevent the occurrence of abusive supervision. Furthermore, organizational managers should provide employees with opportunities to voice their concerns through the use of organizational communication and participation, which can reduce employee silence and subsequently foster employee engagement and satisfaction at work.

This study advances our understanding of how abusive supervision results in poor work motivation and attitudes among employees. This contributes to the literature by identifying employee silence as a suitable mediating mechanism linking the negative associations of abusive supervision with employees' work engagement and job satisfaction.

The purpose of this quantitative study was to investigate Penn State Extension 4-H volunteer leaders’ leadership development needs and preferred delivery methods for leadership development. The participants were 147 volunteer leaders who attended Penn State Extension Annual 4-H Leader Forum and filled out the survey. We found that the overall mean score for leadership skills needs among volunteer leaders was 4.33 (SD =.45). Volunteers’ overall leadership skills needs do not differ based on volunteer gender, level of education, age, and previous volunteer experience. The preferred delivery methods of leadership development for Penn State Extension 4-H volunteer leaders were workshop and in-service training. Leadership education is critical in advancing volunteers’ skills and preparing them to delivery well-developed, state of the art contemporary leadership education programs.

The purpose of this paper is to show how particle scale simulation of industrial particle flows using DEM (discrete element method) offers the opportunity for better understanding of the flow dynamics leading to improvements in equipment design and operation.

The paper explores the breadth of industrial applications that are now possible with a series of case studies.

The paper finds that the inclusion of cohesion, coupling to other physics such fluids, and its use in bubbly and reacting flows are becoming increasingly viable. Challenges remain in developing models that balance the depth of the physics with the computational expense that is affordable and in the development of measurement and characterization processes to provide this expanding array of input data required. Steadily increasing computer power has seen model sizes grow from thousands of particles to many millions over the last decade, which steadily increases the range of applications that can be modelled and the complexity of the physics that can be well represented.

The paper shows how better understanding of the flow dynamics leading to improvements in equipment design and operation can potentially lead to large increases in equipment and process efficiency, throughput and/or product quality. Industrial applications can be characterised as large, involving complex particulate behaviour in typically complex geometries. The critical importance of particle shape on the behaviour of granular systems is demonstrated. Shape needs to be adequately represented in order to obtain quantitative predictive accuracy for these systems.
