Investigating the educational value of social learning networks: a quantitative analysis
Authors: Dafoulas Georgios , Shokri Azam 
Published: November 2016

Purpose
The emergence of Education 2.0 enabled technology-enhanced learning, necessitating new pedagogical approaches, while e-learning has evolved into an instrumental pedagogy of collaboration through affordances of social media. Social learning networks and ubiquitous learning enabled individual and group learning through social engagement and social distribution of knowledge. Nevertheless, these developments have not been supported with extensive studies focusing on quantifying the impact of technology-enhanced learning on students’ progress and achievement. The purpose of this paper is to investigate how a quantitative overview of Facebook’s influence on students’ progress can be incorporated in a proposed e-moderation model of teaching and learning.

Design/methodology/approach
The approach is based on extending Salmon’s (2003) e-moderation model, which provides an emphasis on the theoretical perspectives that support socially situated learning environments of social networks such as Facebook. The findings revealed that students’ grades were positively influenced by the complementary use of Facebook on their courses of study.

Findings
The use of a social learning network also triggered a significant increase in student participation in learning activities delivered over Facebook.

Research limitations/implications
The main research limitations were due to the fact that a single social network was chosen for conducting the experiments. Furthermore, the investigation was narrowed down to a selected range of sessions offered to college and university students as part of their course.

Originality/value
The paper’s contribution is twofold, as it offers an original set of guidelines for conducting social learning network experiments and provides valuable quantifiable findings on the educational value of such networks.
Morocco in the era of eco-urbanism
Authors: Barthel Pierre-Arnaud 
Published: November 2016

Purpose
Environmental urbanism is reflected for the last years in the design of urban megaprojects. This trend is spreading in Morocco to the point that it is considered as the leading player in this emerging field across North Africa. The purpose of this paper is to advance the twofold hypothesis that these specific urban projects are on the one hand tools of capitalism and on the other hand leverage for clear change in the global management project process compared to non-eco-projects. In addition to these two hypotheses, the lack of environmental regulations at the national level and the copy and paste of international standards are serious limits of the approach at the local scale.

Design/methodology/approach
Drawing on an in-depth case study (Benguérir “green town”) and interviews conducted from 2012 to 2014, the paper will aim to build up a critical and operational research on emerging eco-megaprojects in Morocco.

Findings
The paper provides empirical insights and confirms the connection between capitalistic megaprojects and environmental urbanism in Morocco. However, it partially rejects the hypothesis that this new trend opens up dramatic change in the making of projects. This study case points sharp limitations and mismatches between virtuous environmentalism and reality on the ground: the problem of adjusting projects to urban policies, a lack of coordination and trust between local officials and developers, excessive reliance on standards and labels, conformity of developers with the international doxa of urban sustainability. However, eco-urbanism can give birth to better integrated and sustainable projects than “mainstream” urbanism when strongly related to local financial, technical and economic capacities of end users and stakeholders in North Africa.

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

Practical implications
Recommandations are proposed to improve principles in eco-urbanism in Morocco and beyond in North Africa.

Social implications
The skills of residents are a source of education to be tapped into and developed further for eco-projects.

Originality/value
This paper provides an “in situ” analysis of the preparation and implementation of eco-projects in Africa and the national and local adaptations of the internationally promoted eco-city.
Practice education: A snapshot from Australian university programmes
Authors: Gustafsson Louise , Brown Ted , McKinstry Carol , Caine Anne‐Maree 
Published: November 2016

Background/aimPractice education is an integral component of the learning process for occupational therapy students. The dramatic increase in Australian occupational therapy programmes and students enrolled over the last decade is placing exponential demands on universities and practice education providers to meet accreditation and registration requirements. This study aimed to explore practice education from the perspectives of Australian occupational therapy university programmes.MethodsA purpose‐designed survey was emailed to the heads of all Australian occupational therapy programmes. The survey gathered qualitative and quantitative data on courses offered, number of students, practice education hours and models, practice education administration and funding, and challenges for stakeholders. All data were summarised and are presented descriptively.ResultsResponses were received from 21 (95.5%) Australian university occupational therapy programmes, with a total enrolment of 5569 undergraduate and 659 graduate‐entry masters students. Practice education hours were predominantly in the later years of study and used an apprenticeship model for supervision. There was a trend for observation, simulation and service‐learning experiences to be placed in the early years of programmes. Participants reported that the increasing student numbers presented difficulties within the changing clinical contexts. There was a call to re‐examine the 1000‐hour requirement for practice education.ConclusionPractice education is a critical issue for Australian occupational therapy. Increasing student numbers place mounting financial and resource demands on education programmes and practice education providers. There is a need for a national, collaborative approach to develop guidelines and processes to ensure sustainability relating to practice education.
Novel CT‐guided biopsy of isolated perineural spread of adenoid cystic carcinoma along the trigeminal nerve masquerading as chronic trigeminal neuropathy
Authors: Yong Xian Zhang Eric , Dillon Jonathan , Smith Paul , Salinas‐La Rosa Cesar , Jhamb Ashu 
Published: November 2016

SummaryThe differential diagnoses for chronic peripheral neuropathy are broad and diagnosing a cause can be challenging. We present a case of isolated perineural spread of adenoid cystic carcinoma to the trigeminal nerve involving skull base foramina and Meckel's cave in the setting of chronic trigeminal neuropathy and no known prior malignancy. Computed tomography‐guided core (CT) needle biopsy was needed to arrive at a diagnosis and a novel approach was required to obtain tissue from the trigeminal nerve lesion at foramen ovale.
Employer Organizations and Labour Immigration Policy in Australia and the United Kingdom: The Power of Political Salience and Social Institutional Legacies
Authors: Wright Chris F. 
Published: November 2016

AbstractThis article examines employer organizations and labour immigration policy in Australia and the United Kingdom. Drawing on 102 elite interviews, it analyses employer organizations’ preferences and influence over recent reforms. The article builds on Culpepper's arguments relating to the significance of political salience and identifies the importance of various institutional factors, particularly social institutions, in shaping employer organizations’ decisions and engagement with the policy process. Political salience and social institutional legacies are critical for explaining why employer organizations played a central role in driving labour immigration reforms in Australia and a marginal role in the UK. Large intakes of workers from the European Union, which sustained immigration as a high salience issue and fuelled the Brexit campaign, also influenced the strategies of UK employer organizations.

Published: November 2016

BackgroundFamily members of individuals with early psychosis (EP) play critical roles in their engagement with EP services, but family member experiences of those roles are insufficiently understood.MethodsWe conducted semi‐structured interviews with 18 family members of individuals enrolled in EP services during the Recovery After an Initial Schizophrenia Episode‐Implementation Evaluation Study (RAISE‐IES study), to better understand their experiences engaging with EP specialty care and their roles in client engagement in services.ResultsFamily members described diverse experiences with the interplay among distress regarding their loved one's illness, uncertainty engaging with programme staff and highly valued facets of the clinical programme. These included ongoing family outreach and support, frequent communication from staff, programme flexibility and individualization of care. They also described varied and stressful complexities involved in providing practical assistance and encouragement to support their loved one's engagement in care. Competing responsibilities, time and resource limitations, and the intricacy of providing support while fostering autonomy impacted their roles and experiences.ConclusionsGiven key family roles for most EP clients, understanding family members’ highly individual experiences and responding to them in tailored ways is necessary to best support families in helping their loved ones engage in care and recovery as well as navigate their own worry and stress. Recommendations for engaging and supporting family members are highlighted.
Sea lamprey avoid areas scented with conspecific tissue extract in Michigan streams

Published: November 2016

AbstractThree in‐stream experiments were conducted to determine whether sea lamprey, Petromyzon marinus L., tissue extract (alarm cue) and 2‐phenylethylamine hydrochloride (PEA HCl, a putative predator cue) influenced the distribution of migrating adult sea lamprey. Experiments evaluated sea lamprey movement when an odour was applied to (1) a tributary of a larger stream; and (2) half of a stream channel. Fewer sea lamprey entered the tributary and side of the river scented with sea lamprey tissue extract compared to the control treatment. Sea lamprey did not avoid the tributary and side of the river scented with PEA HCl. A final laboratory experiment found no difference in the avoidance response of sea lamprey to PEA HCl mixed with river water vs PEA HCl mixed with water from Lake Huron. As such, the lack of sea lamprey response to PEA HCl in the stream was unlikely to have been caused by the presence of the river water. Rather, the difference between laboratory and field results may be attributed to the complexity of the physical environment.
Advertising and Competition for Market Share between a New Good Producer and a Remanufacturer
Authors: Batabyal Amitrajeet A. , Beladi Hamid 
Published: November 2016

Abstract
We study the strategic interaction between a new good producer and a remanufacturer who use advertising campaigns to compete for a dominant share of the market for a certain good. Each firm chooses one of three possible strategies for running its advertising campaign. The two rival firms care only about capturing a dominant share of the relevant market. Hence, if a firm expects to capture dominant market share with probability p є [0, 1], then its payoff in the game we study is also p. Our analysis leads to four results. First, we provide the normal form representation of the game between the new good producer and the remanufacturer. Second, we specify the game in matrix form. Third, we indicate what happens at each stage of the elimination of strictly dominated strategies. Finally, we show that the iterated elimination of strictly dominated strategies yields a clear and unique prediction about the outcome of the advertising game.

Published: November 2016

AbstractSr2Si5N8:Eu2+ nitride phosphors application for light emitting diodes were synthesized for the first time using less‐expensive and air‐stable entire oxides raw materials, SrCO3, SiO2, and Eu2O3, through a carbothermal reduction and nitridation (CTRN) route. The reaction dynamic processes of the CTRN route and the phase components, photoluminescent properties, quantum efficiency as well as thermal stability for the resultant Sr2Si5N8:Eu2+ phosphors were investigated in detail. High‐crystalline pure Sr2Si5N8:Eu2+ red‐emitting phosphor with acceptant luminescent performances could be obtained through finely controlling addition amount of carbon reductant agent and carefully removing the residual carbon without oxidation damage. An economic route is outlined in this work for the synthesis of nitride phosphors using cost‐effective entire oxides raw materials, thereby driving the development and practical application of nitrides phosphors.

Published: November 2016

Aims and objectivesTo test the effectiveness of a six‐month senior elastic band exercise programme on the self‐perceived health status and sleep quality of older adults living in community settings.BackgroundHealth issues common among older adults living in community settings include poor physical and mental health conditions and sleep quality. Engagement in appropriate exercise programmes facilitates alleviating these health issues among older adults.DesignA quasi‐experimental design was applied. A convenience sample of older adults was drawn from six senior‐citizen activity centres in southern Taiwan. Participants were assigned to either an experimental group (three centres,n = 97) or a control group (three centres,n = 102) based on the senior‐citizen activity centres they attended.MethodsThe participants in the experimental group carried out the Senior Elastic Band exercise programme for six months (three times per week and 40 minutes per session) in addition to their daily activities. The participants in the control group maintained their daily activities. The participants’ self‐perceived health status and sleep quality were examined at the baseline, three‐month interval and six‐month interval.ResultsIn total, 169 participants completed the six‐month study: 84 constituted the experimental group and 85 constituted the control group. At the three‐month interval, the participants in the experimental group had greater improvements in self‐perceived physical health, overall sleep quality, sleep latency and sleep duration compared with those in the control group; these significant changes continued throughout the six‐month study.ConclusionsThe Senior Elastic Band exercise programme showed promising effects in improving the self‐perceived physical health and sleep quality of older adults living in community settings.Relevance to clinical practiceHealthcare professionals can incorporate the Senior Elastic Band exercise programme as one of the health promotion activities for older adults living in community settings.

SummaryIrregular 24 h light/dark cycles with night‐time light exposure and a low amplitude are disruptive for sleep, mood and circadian rhythms. Nevertheless such lighting conditions are quite common in medical care facilities. A controlled clinical trial among 196 cardiology ward patients (mean age 66.5 ± 13.1 years SD) investigated how a patient room lighting intervention affects sleep, appraisal and mood across hospitalization. Patients were either assigned to a standardly‐lit room or to a room with an interventional lighting system offering a dynamic 24 h light/dark cycle with low nocturnal light exposure and 2 h of bright light (1750 lux) during daytime. Measures included wrist actigraphy and questionnaires assessing alertness, sleep quality, anxiety, depression and lighting appraisal. The median length of hospitalization was 5 days in both study arms. Subjective scores on sleep, alertness, anxiety and depression did not differ between arms. Lighting appraisal in intervention rooms was better as compared to standardly‐lit rooms, both in patients (P < 0.001) and staff (P < 0.005). Actigraphic sleep duration of patients improved by 5.9 min (95% CI: 0.6–11.2; P = 0.03 intervention × time effect) per hospitalization day with interventional lighting instead of standard lighting. After 5 days of hospitalization, sleep duration in the lighting intervention rooms increased by 29 min, or a relative 7.3%, as compared to standardly‐lit rooms. A 24 h lighting system with enhanced daytime brightness and restricted nocturnal light exposure can improve some aspects of appraisal and objective sleep in hospital patients. More clinical research is needed to establish the best lighting strategy to promote healing and wellbeing within healthcare settings.
Multi‐Objective Mathematical Programming Approach to Construction Laborer Assignment with Equity Consideration
Authors: Yi Wen , Wang Shuaian 
Published: November 2016

AbstractConstruction laborer assignment is the assignment of laborers in a team to the tasks for a daily work in a construction project. This study proposes a mathematical programming approach to examine the optimal construction laborer assignment problem with the objectives of productivity and occupational health and safety while considering equity between laborers. Several linearization techniques are presented to transform the mathematical programming model into a mixed‐integer linear program, which can be solved by off‐the‐shelf mixed‐integer linear solvers. The proposed model is applied to extensive numerical experiments and the results show that the mathematical programming approach outperforms a conventional heuristic by over 10% in terms of job completion time. This implies considerable overhead, equipment, and manpower savings for the construction industry.

Published: November 2016

SummarySurveillance of candidemia is essential to monitor trends in species distribution and change in the incidence and antifungal resistance. In this study, we aimed to investigate prevalence, resistance rates, antifungal utilization and costs. A 6‐year retrospective analysis of the data belonging to patients with candidemia hospitalized between 2010 and 2016 was performed. The annual usage of fluconazole and caspofungin and the usage of these antifungals in different units were described in defined daily doses (DDD) per 1000 patient days. In total, 351 patients of candidemia were included. Median age of the patients was 45 (0‐88) and 55.1% of them were male. Overall, 48.1% of the candidemia episodes (169/351) were due to C. albicans, followed by C. parapsilosis (25.1%), C. glabrata (11.7%). Length of hospital stay was longer with a median of 20 days among patients with non‐albicans candidemia. Presence of a central venous catheter was found to be an associated risk for candidemia caused by non‐albicans strains. Annual incidence of candidemia increased from 0.10 to 0.30 cases/1000 patient days. Antifungal use was increased over years correlated with the cost paid for it. The policy against candidemia should be specified by each institution with respect to candidemia prevalence, resistance rates, antifungal use and costs.

Published: November 2016

SummaryThe combination of dabrafenib and trametinib is a standard of care for the management of BRAF mutant metastatic melanoma. Clinical trials excluded patients with end‐stage kidney disease (ESKD), and as such, no data are available regarding the safety, efficacy and pharmacokinetics of these drugs in such patients. Here, we present the case of a 78‐yr‐old male patient with ESKD managed with haemodialysis (HD), treated with dabrafenib and trametinib at reduced doses. The patient has had a partial response, and this response continues at 9 months since our last follow‐up without any dose escalation. Treatment was complicated by the development of diarrhoea, attributed to trametinib, necessitating temporary cessation of trametinib. Pharmacokinetic profiling of dabrafenib was undertaken, and its metabolites were similar pre‐ and post‐dialysis and comparable to those in patients with normal renal function. Moreover, HD did not lower the plasma concentration of dabrafenib or trametinib. It is feasible to administer dabrafenib, in combination with trametinib, to patients with ESKD undergoing HD.
The association between grandparental investment and grandparents' happiness in Finland

Published: November 2016

AbstractThere is a lack of studies analyzing the association between grandparental investment and grandparents' happiness. Using nationally representative data from the Generational Transmissions in Finland project (sample n = 2,152 older adults), this study explores (a) whether grandparenthood is associated with self‐evaluated happiness, (b) whether there is an association between grandparental investment (measured by contact frequencies with grandchildren) and a grandparent's self‐perceived happiness, and (c) whether differences in the associations between grandparental investment and happiness vary according to the gender and lineage of a grandparent. Our results show that just being a grandparent is not associated with self‐evaluated happiness among older Finns. However, a positive association was found in the case of maternal grandmothers' investment and happiness.
Religious Symbols
Authors: Whistler Daniel 
Published: November 2016

AbstractIn this essay, I survey the different uses of the concept of the symbol at play in the philosophy of religion. Considering that historically theories of the symbol have frequently had significant religious presuppositions and implications, I suggest that one might expect that the symbol would play a significant role in current research. This is not the case, however, since the very specific metaphysical, linguistic and theological premises that have traditionally informed much theorisation of the symbol tend to be unpopular today. The main exception is Peircean symbolics which has recently been re‐appropriated by a variety of philosophical fields, including philosophy of religion. To open up further contexts for contemporary deployments of the symbol, I look to contemporary public and legal debates concerning the right to wear religious symbols as an area of research unjustly neglected by philosophers of religion: much of the inchoate conceptual work being done in the legal cases themselves would naturally feed into academic philosophical discussion of the symbol.
