Elastohydrodynamic lubrication of circular contacts at pure squeeze motion with micropolar lubricants
Authors: Chu Li Ming , Lin Jaw-Ren , Chang Yuh-Ping , Wu Chung-Chun 
Published: November 2016

Purpose
This paper aims to explore pure squeeze elastohydrodynamic lubrication (EHL) motion of circular contacts with micropolar lubricants under constant load. The proposed model can reasonably calculate the pressure distributions, film thicknesses and normal squeeze velocities during the pure squeeze process.

Design/methodology/approach
The transient modified Reynolds equation is derived in polar coordinates using micropolar fluids theory. The finite difference method and the Gauss–Seidel iteration method are used to solve the transient modified Reynolds equation, the elasticity deformation equation, load balance equation and lubricant rheology equations simultaneously.

Findings
The simulation results reveal that the effect of the micropolar lubricant is equivalent to enhancing the lubricant viscosity. As the film thickness is enlarged, the central pressure and film thickness for micropolar lubricants are larger than those of Newtonian fluids under the same load in the elastic deformation stage. The greater the coupling parameter (N), the greater the maximum central pressure. However, the smaller the characteristic length (L), the greater the maximum central pressure. The time needed to achieve maximum central pressure increases with increasing N and L.

Originality/value
A numerical method for general applications was developed to investigate the effects of the micropolar lubricants at pure squeeze EHL motion of circular contacts under constant load.

Authors: Arsić Dušan , Lazić Vukić , Mitrović Slobodan , Džunić Dragan , Aleksandrović Srbislav , Djordjević Milan , Nedeljković Branislav 
Published: November 2016

Purpose
The purpose of this study is to show which filler metal is the best for hard facing. Because the quality of the surface layer has a great influence on the working life of parts, the purpose was to extend the working life of parts exposed to intensive wear. The tested hard-faced models were made of low carbon steel to save the expensive base metal and to analyze the possibilities of extending the service life of existing structural parts.

Design/methodology/approach
Samples were prepared from plates hard faced with various filler metals. Samples were then subjected to experimental testing – testing of tribological properties and hardness and microstructure. Testing was done in conditions similar to real ones – with a sliding speed of 0.25, 0.5 and 1 m/s and with a load of 50, 75 and 100 N and in most rigorous dry conditions. Research was done by using a combination of experimental and theoretical approaches.

Findings
The paper shows the results of the experimental testing of four different filler metals aimed for hard facing of parts exposed to highly intensive wear. Results shown that CrWC 600 alloy is the most favorable filler metal for hard facing of parts such as those of construction mechanization and those subjected to intensive abrasive wear at stone mines.

Practical implications
All obtained results are real and fully applicable, as there is a huge industrial need for these types of technologies. With the application of these technologies, beside money savings, the working life of parts can be significantly extended.

Originality/value
The research presented in this paper was conducted because of the lack of results from this area in Serbia and because of the necessity for application of obtained results in companies for road maintenance and stone excavation in the region of Šumadija, Serbia.
Experimental study of the tribological properties of an elevator’s brake linings
Authors: Durak Ertugrul , Yurtseven Hakan Ali 
Published: November 2016

Purpose
This paper aims to design and manufacture a wear-test rig performing reciprocating movement that is more relevant to the elevator brake system. Also, a sample test result that was conducted in this experimental set-up is presented to evaluate the tribological properties of the brake linings of the elevator system that are activated in emergencies.

Design/methodology/approach
The brake linings are some of the most important security elements in elevators. The friction and wear properties of these brake linings have great importance for both safety and comfort. Elevator brake linings are often used in conjunction with guided rails under dry and boundary lubrication conditions. Therefore, friction coefficient and wear types occurring in the brake linings may be different. The tribological properties of the brake lining material in the literature are generally identified using a pin-on-disc wear-tester. The pin is contacted by rotating a disc in this wear-test rig. However, as the brake linings and guide rails do not have a reciprocating movement (linear translational motion) on each other, this wear-test rig is not suitable for brake linings and guide rails in the elevator system.

Findings
A sample test result that was conducted in this experimental set-up is presented to evaluate the tribological properties of the brake linings of the elevator system that are activated in emergencies. In these experiments, three different brake lining materials that are widely used in the elevator car guide rails in Turkey were tested under different speeds and loads.

Originality/value
The paper provides information about how to evaluate the tribological properties of the brake linings of the elevator system that are activated in emergencies. Also, it offers practical help for the manufacturer and researcher in the elevator sector.
Evaluation of hotel website contents: existence-importance analysis
Authors: Salem Islam El Bayoumi , Čavlek Nevenka 
Published: November 2016

Purpose
The purpose of this study is twofold: it aims to examine hotel website features by conducting a content analysis and it analyses customers’ viewpoints about the importance of the contents of hotel websites. The study involves a quantitative method of measurement and evaluation of the information provided by hotel websites. It tries to evaluate the richness of definite and ample information dimensions, which as a whole constitutes the information services offered through the website.

Design/methodology/approach
The study is based on two pillars: all five-star hotel chains (113 hotels) in Egypt as the population frame to evaluate the contents of their websites; and a sample of 406 customers selected to examine the customers’ views on the importance of the contents of hotel websites. This study proposes a quantitative evaluation frame of all dimensions provided by hotel websites which is developed, tested and validated.

Findings
The study has revealed important findings that can help hotel managers to adjust the information on the websites to be more efficient and customer-oriented.

Research limitations/implications
Because of the chosen research approach, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed frame again in further studies.

Practical implications
The study includes implications for the development of hotel website evaluation from the perspective of two sides, hotel managers and customers, by using a unique quantitative evaluation model.

Originality/value
This research has for the first time combined statements from the perspective of two sides – hotel managers and customers.
High tech meets high touch in upscale hotels
Authors: Brochado Ana , Rita Paulo , Margarido Ana 
Published: November 2016

Purpose
This paper presents an analysis of the impact of current technologies on customer experiences in upscale hotels and assesses the potential of the latest technologies for enhancing customers’ stay.

Design/methodology/approach
A two-step approach was applied in this study. The qualitative phase included an examination of upscale hotel websites, interviews with hotel managers and an internet search regarding the latest technological innovations in hotels. In the quantitative stage, a questionnaire was developed for hotel guests, generating a sample of 310 valid completed questionnaires.

Findings
The results reveal that hotel guests value digital involvement in their hotel experience. Moreover, business travellers and younger generations give greater importance to latest technologies.

Originality/value
This study analyses the most innovative technologies, providing guidance for hoteliers wishing to upgrade or implement new technologies. Based on the findings, hoteliers can achieve greater differentiation by offering the most important and latest technology to guests, enhancing their experience and attracting new customers, which can potentially lead to increased revenues. The study’s results are also important because they include the perceptions of both managers and customers.
Tourists’ intention to give permission via mobile technology in Thailand
Authors: Erawan Theera 
Published: November 2016

Purpose
The purpose of this paper is to examine tourist behavior regarding changes in privacy issues and the advent of mobile technology, based on theoretical foundations and empirical testing.

Design/methodology/approach
A conceptual framework was developed based on a “three-pronged approach” to cross-validate results from both qualitative (literature reviews and expert interviews) and quantitative (field survey) approaches. Structural equation modeling was used to test the conceptual framework and hypotheses.

Findings
According to the findings, tourists perceived advertising via mobile technology as an informative source. New findings emerged apart from the literature in which advertising value was found to drive attitude, perceived behavioral control and subjective norms. Moreover, tourists’ intention to give permission via mobile technology was driven by advertising value via attitude and subjective norms.

Research limitations/implications
This study is limited to Thailand tourism context. Further, conceptual framework generalization should be taken into account as future research in other considerable context.

Practical implications
The results provide useful information for both government and tourism-related businesses in planning effective marketing communications strategies.

Originality/value
The conceptual framework in this study was developed based on theoretical foundations, along with both quantitative and qualitative methodologies (that is, using a “three-pronged approach”). This study is among the first in Thailand tourism context that demonstrated an extension of the academic perspective by integrating two important theoretical foundations.
Dementia: towards a perceptual control theory perspective
Authors: McEvoy Phil , Eden John , Morris Lydia , Mansell Warren 
Published: November 2016

Purpose
The purpose of this paper is to explore the psychosocial experiences of people living with dementia using a perceptual control theory (PCT) perspective.

Design/methodology/approach
Conceptual paper.

Findings
The paper suggests that people with dementia may control their perceptions by using four modes of control: control, automatic, passive observation and imagination.

Research limitations/implications
The paper highlights how a perceived sense of “too little” or “too much” control can create psychological and emotional distress, as people with dementia seek to respond to the changing contextual circumstances of their lives. However, more work needs to be done to develop specific PCT informed strategies that may serve the goal of helping people who are living with dementia to maximise their functioning and alleviate their distress.

Originality/value
The potential benefits of adopting a PCT perspective to understand the experiences of people living with dementia have only been explored in a relatively superficial way. This paper is a first attempt to develop a more considered analysis.
Quality in residential care: exploring residents’, family members’, managers’ and staff perspectives
Authors: Jaye Chrystal , Tordoff June , Butler Mary , Hale Beatrice , McKechnie Roz , Robertson Linda , Simpson Jean 
Published: November 2016

Purpose
The purpose of this paper is to explore the indicators of quality in care for people working and living in aged residential care (ARC) settings.

Design/methodology/approach
This research was conducted using an ethnographic design in two distinct ARC facilities in a New Zealand city, a large facility with residential, dementia and hospital level care, and a small family owned facility providing residential care only. In total, 50 hours of observational data were collected, and semi-structured interviews were conducted with 21 people, including managers, careworkers, nurses, family members and residents. These data were thematically analysed using the constant comparative method.

Findings
The main indicators of quality for staff, family and residents included: a home-like, friendly and safe environment; good medical and personal care; respect for the residents; and good staff. Participants also acknowledged the need for adjustments by residents to living in aged care; and the challenges of caring for increasingly frail residents.

Originality/value
Findings support the growing recognition of a need for resident-centred approaches to ARC that are reflected in government policy and regulatory apparatus. Managers in ARC facilities must balance adherence with health and safety standards, and providing an environment where their residents can enjoy a meaningful life that has purpose and value.
“Are you going to come and see us again soon?” An intergenerational event between stroke survivors and school-children
Authors: Lane Kathleen 
Published: November 2016

Purpose
A one-hour intergenerational event held at an infant school in Norfolk, England, aimed to increase the citizenship experience of young children and their awareness of what it means to live with stroke, and to address social isolation or self-confidence in communicating among stroke survivors with aphasia. It was also intended to gauge whether this activity might provide a basis for future research. The paper aims to discuss these issues.

Design/methodology/approach
Four community-dwelling stroke survivors with aphasia were recruited. In total, 12 pupils aged six and seven were selected by their Year 2 teacher and head-teacher. At the event, participants sat in groups of one adult and three pupils and engaged in writing, hand-tracing and talking about pictures. The author circulated among the groups to facilitate engagement.

Findings
All participants enjoyed interacting together in the activities. The pupils gained insights into the stroke survivors’ lived experience and wanted them to return to “see us again soon”; the adults valued being in the “real world” and practising their conversation in activities different from their usual routines. Feedback indicated the value of the engagement and that participants welcomed similar intergenerational opportunities. The author will develop a research application exploring enablers, barriers and benefits of this type of engagement.

Originality/value
The event gave a rare opportunity for stroke survivors with aphasia to participate in intergenerational activities and for children to engage with vulnerable older adults. It demonstrated the value of interactions in which learning and insights are obtained on both sides. It also provided evidence that pursuing research in this field is feasible.
Facilitating organizational learning through agent-based modeling and simulation experimentation
Authors: Baškarada Saša , Chandran Arvind , Shokr Mina , Stewart Christopher 
Published: November 2016

Purpose
In addition to requiring high absorptive capacity, contemporary organizations operating in highly dynamic and complex environments also require the ability to create knowledge internally, within the organization. While the organizational learning (OL) literature has produced a plethora of theories and frameworks, there has been relatively little empirical research on specific mechanisms for internal knowledge generation. Accordingly, this paper aims to answer calls for more research on mechanisms for internal generation of organizational knowledge.

Design/methodology/approach
This paper is an in-depth case study in the Australian Defence Organisation (ADO).

Findings
The paper presents a cyclical eight-stage knowledge generation process and demonstrates how agent-based modeling and simulation (ABMS) may be used to facilitate OL.

Originality/value
By detailing an in-depth case study of an ABMS mechanism for internal knowledge generation in the ADO, this paper provides a novel and relevant contribution to the OL literature.
Attitudes towards ageing and their impact on health and wellbeing in later life: an agenda for further analysis
Authors: Robertson Guy 
Published: November 2016

Purpose
The purpose of this paper is to provide a high-level overview of a substantial body of research on the impact that negative attitudes towards ageing have on the health and wellbeing outcomes of people in later life and to highlight the need for a more interdisciplinary approach towards older people’s wellbeing.

Design/methodology/approach
The paper draws from an initial analysis of over 70 peers reviewed and published studies on the psychosocial impact of negative stereotypes about ageing.

Findings
There is overwhelming evidence that the way in which people think about ageing can have a very significant adverse impact on a wide array of health and wellbeing outcomes. This research evidence is largely unknown, nor operationalised, within the field of health and social care policy or service development.

Practical implications
The fact that beliefs and attitudes can have such a profound impact on health and wellbeing outcomes suggests the possibility of psychosocial interventions to address them in order to improve older people’s experience of later life. There is a need for a much more interdisciplinary research agenda to take these findings forward.

Social implications
The evidence suggests the need for a much more rigorous and comprehensive approach to addressing the effects of socially constructed ageist attitudes.

Originality/value
Whilst the research itself is not new, the originality of this paper is its attempt to bring data from a different discipline into the health and social care ambit and thereby extend the knowledge base and create the possible conditions for the development and application of new psychosocial interventions to improve the lives of older people.
Doing memory work with older men: the practicalities, the process, the potential
Authors: Blake Vic , Hearn Jeff , Barber Randy , Jackson David , Johnson Richard , Luczynski Zbyszek 
Published: November 2016

Purpose
The purpose of this paper is to describe the process of setting up and participating in a collective memory work group of older men, with a focus on the making and unmaking of older men and masculinities through age, ageing, gender, gendering, and other intersections.

Design/methodology/approach
Participant review and reflection on collective of memory work group of older men.

Findings
Memory work is located in relation to related but different forms of writing and group work, emphasizing how in this method everyone becomes a writer, an author, a listener, a reader, a discussant, and a commentator. This provides a novel way to explore the constructions and intersections of ageing, gender, men, and masculinities.

Social implications
The potential of memory work, both for working with older men, and more generally is outlined. Key issues are: genuine and collective commitment to substantive change, not just at a personal level, but also at wider social/political/cultural levels; willingness to trust in the other members of the group, an issue that may be difficult for some men; and commitment for caring for one another especially in their moments of greatest vulnerability.

Originality/value
There is little, if any, other writing on this approach to ageing, men, and masculinities. The paper is therefore of great value, and may stimulate wider application of this approach.
“Something to get out of bed for”: creative arts for a happily ageing population
Authors: Cann Paul 
Published: November 2016

Purpose
The purpose of this paper is to relate the growing body of evidence about the impact of creative arts on the health and well-being of older people to the debate about active ageing, prevention and demographic change.

Design/methodology/approach
It draws on a range of researched examples in order to illustrate the impact of three different art forms – singing, dance and visual arts – on health and well-being.

Findings
The evidence exists in increasing volume and diversity that creative arts not only improve personal feelings of well-being but also key physiological measures. The arts are increasingly recognised as playing a major potential role in the delivery of health and social care interventions. Greater recognition and action are needed from policy makers, commissioners and care providers in health and social care that the arts are not a marginal and elitist avenue but a mainstream tool supporting older people to remain active, healthy and independent. Importantly, they represent a powerful source of motivation, agency and confidence.

Social implications
It argues that creative arts should become an integral and more prominent part of ageing policy. The evidence exists in increasing volume and diversity that creative arts not only improve personal feelings of well-being but also key physiological measures. The arts are increasingly recognised as playing a major potential role in the delivery of health and social care interventions. Greater recognition and action are needed from policy makers, commissioners and care providers in health and social care that the arts are not a marginal and elitist avenue but a mainstream tool supporting older people to remain active, healthy and independent. Importantly, they represent a powerful source of motivation, agency and confidence.

Originality/value
An important research challenge remains, namely to plot cause (arts intervention) and effect (reduced demand on health and care services), if the creative arts are to occupy a central place in commissioning investment at a time of acute financial stringency in the public sector.
Meeting the housing needs of older people: the key to better care and a more integrated society?
Authors: Watts Tony 
Published: November 2016

Purpose
The purpose of this paper is to highlight the need for a longer term view of how to address the needs of older people for suitable housing.

Design/methodology/approach
The author draws from his experience of meetings and discussions with numerous older people through his national and regional roles in the ageing sector.

Findings
There is a need to hear the voice of older people, to emphasise “rightsizing” rather than “downsizing”, to create self-supporting communities rather than building houses, to focus on care and repair services and finally to ensure that all new homes are built to enable occupiers to age in place.

Originality/value
The author draws on extensive experience of involvement in the older people’s movement to provide a challenging analysis of the housing situation as it affects older people.
