Predicting the likelihood of voiced complaints in the self-service technology context

There is considerable evidence to suggest that consumer dissatisfaction with self-service technologies is widespread. However, there has been little conceptual or empirical scrutiny of the likelihood that consumers will complain to an organization (likelihood of voice) in this context. This study contributes to the service domain by testing empirically a model of the antecedents of consumers' likelihood of voice in unsatisfactory encounters with self-service technologies. A model is tested that combines established antecedents of voice, such as likelihood of voice success, and those that have not yet been considered, including self-service technology powerlessness and need to vent. The results support the proposed model in general. Theoretical and managerial implications of the findings are discussed.

Getting your life back on track after stroke : a phase II multi-centered, single-blind, randomized, controlled trial of the Stroke Self-Management Program vs. the Stanford Chronic Condition Self-Management Program or standard care in stroke survivors

Background Self-management is seen as a primary mechanism to support the optimization of care for people with chronic diseases such as symptomatic vascular disease. There are no established and evidence-based stroke-specific chronic disease self-management programs. Our aim is to evaluate whether a stroke-specific program is safe and feasible as part of a Phase II randomized-controlled clinical trial.
Methods Stroke survivors are recruited from a variety of sources including: hospital stroke services, local paper advertisements, Stroke South Australia newsletter (volunteer peer support organization), Divisions of General Practice, and community service providers across Adelaide, South Australia. Subjects are invited to participate in a multi-center, single-blind, randomized, controlled trial. Eligible participants are randomized to either;
• standard care,
• standard care plus a six week generic chronic condition self-management group education program, or,
• standard care plus an eight week stroke specific self-management education group program.
Interventions are conducted after discharge from hospital. Participants are assessed at baseline, immediate post intervention and six months.
Study Outcomes The primary outcome measures determine study feasibility and safety, measuring, recruitment, participation, compliance and adverse events.
Secondary outcomes include:
• positive and active engagement in life measured by the Health Education Impact Questionnaire,
• improvements in quality of life measured by the Assessment of Quality of Life instrument,
• improvements in mood measured by the Irritability, Depression and Anxiety Scale,
• health resource utilization measured by a participant held diary and safety.

Conclusion The results of this study will determine whether a definitive Phase III efficacy trial is justified.

Analyzing international travelers' profile with self-organizing maps

It is generally agreed that knowledge is the most valuable asset to an organization. Knowledge enables a business to effectively compete with its competitors. In the tourism context, an in-depth knowledge of the profile of international travelers to a destination has become a crucial factor for decision makers to formulate their business strategies and better serve their customers. In this research, a self-organizing map (SOM) network was used for segmenting international travelers to Hong Kong, a major travel destination in Asia. An association rules discovery algorithm is then utilized to automatically characterize the profile of each segment. The resulting maps serve as a visual analysis tool for tourism managers to better understand the characteristics, motivations, and behaviors of international travelers.

Governing the working population : knowledge, self and power in workplace health programs

This paper reports a case study of a workplace health programme in an international information technology company. Discourse analysis was used to identify how specific forms of knowledge create understandings of health and influence power relations between employee and organization. These forms of knowledge are shown to make employee health both visible and invisible in particular ways. Workplace health discourse encourages the employee to take responsibility for self-assessment and behaviour adjustment to become healthier employees. This is shown to be an ethical project which results in the alignment of personal and corporate goals.

In vitro response to functionalized self-assembled peptide scaffolds for three-dimensional cell culture

Nanomaterials are rich in potential, particularly for the formation of scaffolds that mimic the landscape of the host environment of the cell. This niche arises from the spatial organization of a series of biochemical and biomechanical signals. Self-assembling peptides have emerged as an important tool in the development of functional (bio-)nanomaterials; these simple, easily synthesized subunits form structures which present the properties of these larger, more complex systems. Scaffolds based upon these nanofibrous matrices are promising materials for regenerative medicine as part of a new methodology in scaffold design where a "bottom-up" approach is used in order to simulate the native cellular milieu. Importantly, SAPs hold the potential to be bioactive through the presentation of biochemical and biomechanical signals in a context similar to the natural extracellular matrix, making them ideal targets for providing structural and chemical support in a cellular context. Here, we discuss a new methodology for the presentation of biologically relevant epitopes through their effective presentation on the surface of the nanofibers. Here, we demonstrate that these signals have a direct effect on the viability of cells within a three-dimensional matrix as compared with an unfunctionalized, yet mechanically and morphologically similar system. © 2014 Wiley Periodicals, Inc.

Iran and the Shanghai cooperation organization : ideology and realpolitik in Iranian foreign policy

The Islamic Republic of Iran has pursued full membership in the Shanghai Cooperation Organisation (SCO). In doing so, Iran has appeared to be unfazed by the prospect of allying with Russia and China, two countries which have systematically suppressed their Muslim minorities for decades. Similarly, the SCO's Central Asian member states are led by individual leaders who are generally believed to rule in spite of their populations. As a result, Iran's eagerness to join the SCO may appear to contradict its self-promoted image as the champion of Muslim interests, but in reality it sits nicely within its overarching enmity for the USA. Indeed, the SCO is seen as a geopolitical counterweight to the USA. For Iran, this geopolitical opportunity overrides ideological imperatives, with the gap between ideology and geopolitics most evident under the presidency of Mahmoud Ahmadinejad.

Self-assembled peptide nanostructures for the fabrication of cell scaffolds

The fabrication of artificial scaffolds that effectively mimic the host environment of the cell have exciting potential for the treatment of many diseases in regenerative medicine. In particular, appropriately designed scaffolds have the capacity to support, replace, and mediate the transplantation of therapeutic cells in order to regenerate damaged or diseased tissues. To achieve these goals for regeneration, the engineering of an environment structurally similar to the native extracellular matrix (ECM) is necessary in order to closely match the chemical and physical conditions found within the extracellular niche. Recently, self-assembled peptide (SAP) hydrogels have shown great potential for such biological applications due to their inherent biocompatibility, propensity to form higher order structures, rich chemical functionality and ease of synthesis. Importantly, it is possible to control the organization and properties of the target materials as the chemical structure is determined by amino acid sequence. Here, the development of SAP hydrogels as functional cell scaffolds and useful tools in tissue engineering is reviewed.

Do cognitive, language, or physical impairments affect participation in a trial of self-management programs for stroke?

BACKGROUND: Research studies may have limited generalizability when survivors of stroke with physical, language, or cognitive impairments are excluded. AIMS: To assess whether presence of cognitive, language, or global impairments affects participation in self-management programs.

METHODS: Stroke survivors were recruited in South Australia from seven hospitals or via advertisements into a randomized controlled trial (1:1:1 ratio) of a Stroke Self-Management Program, the Stanford chronic condition self-management program, or standard care. Impairment status was measured using: Cognistat (cognition), Frenchay Aphasia assessment (language), modified Rankin Score (mRS; where score 3-5 = global disability).

PRIMARY OUTCOMES: participation (i.e. booked, accessed, and completed a program (defined as attending ≥ 50% of sessions)) and safety (i.e. adverse events). Outcomes were compared by impairment status. RESULTS: Among 315 people screened 143/149 eligible were randomized (median age 71 years; 41% male; with impairments: 62% cognitive, 34% language, 64% global disability). Participation did not differ by cognitive or language impairment status (cognitive 75%, no cognitive 68%, p = 0.54; language 78%, no language 69%, p = 0.42). However, participation did vary by global impairment status (global disability 61%, no disability 96%, p < 0.001). Participants with cognitive impairment experienced more adverse events (severe n = 9 versus no cognitive impairment n = 1).

CONCLUSION: Survivors of stroke with cognitive, language, or global impairments are able to participate in self-management programs and should be included in these types of research studies or programs. Reduced participation by those with global disability and the possibility of more adverse events in people with cognitive impairments needs to be considered.
