Using case vignettes as the research method, this article analyzes the operations of a large number of these companies and presents a set of building blocks that are useful for generating the business models of SES companies. An examination of the successes and failures in the practices of SES companies provides a number of managerial recommendations.
Demand side management in smart grid: A laboratory-based educational perspective
Authors: Pattanaik P Akash , Sahoo NC , Mishra S
Published: January 2019

Demand side management is an important operational aspect of smart grid focusing on cost and efficiency optimisation by load management and control. With growing power demand and shortage of energy resources, it is necessary to educate people on the benefits of demand side management. In the present Electrical Engineering curriculum, demand side management is also being taught as a core topic in power system courses. Hands-on laboratory sessional in demand side management will definitely assist the students in their understanding of the working principles and implementation challenges of demand side management. In this paper, a small-scale laboratory prototype demand side management system has been implemented and is being used in power system laboratory work for Electrical Engineering students at IIT Bhubaneswar (India). In this demand side management prototype system, a Central Energy Management Unit, interfaced with all load/energy control units at each customer end, is used for centralised load scheduling control. A data-entry circuit is used at each customer end for prior transmission of load scheduling request. For wireless data communication among various units, a Global System for Mobile communication is adopted. The laboratory setup consists of few loads, ARDUINO microcontrollers, relay modules, current sensors, MATLAB interface (at Central Energy Management Unit end) and Global System for Mobile communication modules. The learning performance/efficiency of the students has been evaluated by the students’ responses to a questionnaire before and after the experiment being conducted by them and it has been found to be noteworthy highlighting the educative efficacy of the well-designed experiment on demand side management.
A Comparative Analysis of Collaborative Environmental Management of Natural Resources in Sub-Saharan Africa: A Study of Cameroon and South Africa
Authors: Musavengane Regis , Tantoh Henry Bikwibili , Simatele Danny
Published: January 2019

In Africa, rural communities thrive on social capital and tend to have a number of commonalities that force them to share natural, physical and social resources. It has been a trend in sub-Saharan Africa to have either formal or informal collaborative management agreements to manage common pool resources (CPRs) to accommodate different actors and interests. This paper draws lessons from past and contemporary collaborative schemes in Cameroon and South Africa to enhance the practice and governance processes of natural resources in sub-Saharan Africa in order to promote sustainable development. Using research methods inspired by the tradition of participatory research to collect field-based data and complemented by reflections on previous and existing studies, the paper highlights the importance and benefits of participatory democracy as opposed to representational democracy in co-management of natural resources in rural spaces. It further discusses the need to redefine the roles of national and local governments, the youths and women in ensuring effective participation and the essence of unifying the judicial and culture. To guarantee sustainability of collaborative community-based natural resources, the paper emphasises the role and importance of youth and women empowerment. These issues have been discussed within the broader sustainability discourse.
Modeling the robotic manipulation of woven carbon fiber prepreg plies onto double curved molds: A path-dependent problem
Authors: Krogh Christian , Glud Jens A , Jakobsen Johnny
Published: January 2019

This paper investigates the behavior of woven prepreg plies being placed on a weakly double curved mold by a robot. It is essential that the draped configuration is free from wrinkles. The baseline is a virtual draping environment that can plan and simulate robot draping sequences. It consists of a kinematic mapping algorithm for obtaining target points for the grippers on the mold surface. A simple motion planner is used to calculate the trajectories of the grippers. Here, two conceptually different draping strategies are employed. Finally, the two generated draping sequences are simulated using a transient, non-linear finite element model and compared w.r.t. their predicted wrinkle formations. Material data are obtained by means of tension, bias-extension and cantilever tests. The numerical examples show that the virtual draping environment can aid in developing the automatic draping system but that the generation of feasible draping sequences is highly path dependent and non-trivial.
The failure mechanism and energy-absorbing characteristics of composite thin-walled C-channels subject to low-speed axial compression
Authors: Zhenyu Feng , Jiang Xie , Shanshan Song , Haolei Mou , Xuan Su , Xuehan Zhang
Published: January 2019

To analyze the failure mechanism and energy-absorbing characteristics of composite thin-walled C-channels subject to the low-speed axial compression, 12 groups of T700/MTM28 specimens with three different layer numbers and four different layups were fabricated and tested. The failure modes and load–displacement curves were observed, and then the effects of layer numbers and layups on failure mechanism and energy-absorbing characteristics were further analyzed based on the crashworthiness indicators, such as peak crushing force ( Fmax), mean crushing force ( Fmean), specific energy absorption ( SEA) and crushing force efficiency ( CFE). The results show that for the C-channels with 0° ply, overall instability occurs, which results in a reduction of SEA. The C-channels with 0°/90° ply, ± 45° ply and 45°/90°/−45°/0° ply exhibit the stable progressive crushing progress with the local buckling failure mode, consisting of local buckling, fiber breakage, matrix cracks, delamination and corner cracking. Besides, the SEA of C-channels with 45°/90°/−45°/0° ply increases with the increasing of layer numbers, and the C-channels with 45°/90°/−45°/0° ply have greater potential for the design and application of energy-absorbing structures.
Having Control Over and Above Situations: The Influence of Elevated Viewpoints on Risk Taking
Authors: Jami Ata
Published: January 2019

This article examines how consumers’ exposure to the viewpoint of high versus low vertical position changes their risk-taking behavior. The author proposes that consumers’ views of scenery from a high physical elevation induce an illusory sense of control, which in turn intensifies risk taking. Multiple studies show that exposure to the viewpoint of high vertical positions increases risk taking in both laboratory settings (Studies 1a, 1b, and 1c) and real settings (Study 4). In addition, the author demonstrates that an illusory sense of control mediates the effect of an elevated viewpoint on risk taking (Study 2) and that the effect of elevation on risk taking is attenuated when people use a low-level mental construal to process visual information (Study 3).
Speaking for “Free”: Word of Mouth in Free- and Paid-Product Settings
Authors: Bond Samuel D. , He Stephen X. , Wen Wen
Published: January 2019

This research examines drivers of consumer word of mouth (WOM) in free-product settings, revealing fundamental differences with traditional, paid-product settings. The authors build and investigate a theoretical model that highlights two unique characteristics of free products (reciprocity motivation and diminished adoption risk) and considers their implications for WOM sharing. Results of a retrospective survey, two controlled experiments, and an analysis of more than 5,000 mobile apps at Google Play and Apple’s App Store reveal that consumers are generally more likely to share their opinions of free products than paid products, because of feelings of reciprocity toward the producer. However, this difference is reduced when prior consumer WOM is low in volume and highly disperse, signaling greater adoption risk. These findings contribute to nascent understanding of free-product marketing while offering new insights for catalyzing consumer WOM.
Institutional Voids and Organization Studies: Towards an epistemological rupture
Authors: Bothello Joel , Nason Robert S. , Schnyder Gerhard
Published: January 2019

In this essay, we critique the usage of the term ‘institutional void’ to characterize non-Western contexts in organizational studies. We explore how ‘conceptual stretching’ of institutional voids – specifically, the theoretical and geographic expansion of the concept – has led not only to poor construct clarity, but also pejorative labelling of non-Western countries. We argue that research using this term perpetuates an ethnocentric bias by deifying market development and overlooking the richness and power of informal and non-market institutions in shaping local economic activity. We call for an ‘epistemological rupture’ to decolonize organizational scholarship in non-Western settings and facilitate contextually grounded research approaches that allow for more indigenous theorization.
Using the LM3 method to evaluate economic impacts of an on-line retailer of local food in an English market town
Authors: Mitchell Andrew , Lemon Mark
Published: January 2019

The paper presents a case study of an on-line retailer of locally sourced food and drink to explore its local economic impacts on an English East Midland market town. The analysis is based on the LM3 survey method which tracks the value of an investment for a local economic area. While the findings suggest a positive impact, the reliability of third round data is disputed, and generates approximations rather than precise indicators of added economic value. In acknowledgement of this limitation, two approaches to working with round three data are compared. The paper concludes with recommendations for using this method in future research, as well as suggestions that might inform the development of a local or regional sustainable and resilient economic development policy framework.
Queue Spillback and Demand Uncertainty in Dynamic Network Loading
Authors: Boyles Stephen D. , Ruiz Juri Natalia
Published: January 2019

In the field, queue spillback contributes substantially to urban congestion. Therefore, most dynamic network loading models either explicitly include spillback, or frame a failure to model spillback as an unfortunate consequence of mathematical or computational tractability that should be relaxed in future work. Although models with spillback are undeniably more realistic, they are also less robust to errors in input demand. We show that when there is high uncertainty in input demand, excluding spillback can actually reduce error by reducing sensitivity to demand errors. Our demonstrations include a small network that can be solved analytically, and dynamic user equilibrium on two real-world networks representing Austin, TX, and San Antonio, TX. We conclude that model realism must be carefully balanced against the accuracy of the input parameters, and the sensitivity of the model to any such errors in these inputs.
Clinical leadership in reducing risk: Managing patient airways
Authors: Brown N. Shira , Chirico John , Hollidge Melanie , Randall Jill
Published: January 2019

Niagara Health, a multi-site hospital organization, has developed a multimodal, comprehensive strategy to manage patients with a Difficult Airway (DA) in a non-operative setting. The Difficult Airway Pathway (DAP) is an evidence-based strategy aimed to train staff to reduce critical events. The DAP initiative aligns with the LEADS framework for change management and includes an annual review of reported critical incidents and an Enterprise Risk Management (ERM) Assessment Summary, with the goal to “create a regional systematic approach to support personnel, equipment and education.” The guiding vision is: “Right people, Right equipment, Right timing: No failed airway.” Preliminary evaluation suggests the strategy reduces morbidity and mortality of difficulty airway incidents outside the operating room.
Key driving factors for product and service innovations in UK university spin-offs
Authors: Baines Ning , Smith Helen Lawton
Published: January 2019

University spin-offs (USOs) are an important firm class since they constitute an economically important sub-group of high-tech start-up firms: they have, consequently, engendered many academic studies. However, what the firms deliver by way of innovation in the form of new products and services has largely been missing from the academic entrepreneurship literature. By adopting a mixed research methodology of in-depth interviews and a survey, this study highlights key factors associated with the success of product and service development by USO firms in the United Kingdom – such as understanding customer needs, networks, clear market analysis, applications of technology, and the vision, mission and value of the company. The findings resonate with various studies in innovation management on the key elements of product and service performance predictors. The article also helps to fill a gap in the academic entrepreneurship literature by providing an understanding beyond the success factors in setting up USOs. The study should therefore raise the awareness of and benefit various actors (e.g. academic entrepreneurs and technology transfer offices) with regard to the provision of the activities and skills required to develop products and services successfully.
The response of two-wheeler tires to three-body wear phenomena by experimental simulation of off-road terrains
Authors: Pai Dayananda , Pai Anand , Kumar Saahil , Deb Anubhav
Published: January 2019

The operation of two wheelers frequently encounters off-road terrain comprising loose particles of sand and soil, which setup three-body abrasive wear phenomena affecting the tire life. To evaluate the response of two-wheeler tires on such terrains, the dry abrasive wear behavior of two-wheeler tires was experimentally determined using a three-body wear test apparatus. Three different mixtures of sand and granite dust of varying grit size, 100, 200, and 300 µm, were employed to represent the abrasive cluster, typical of the varying roughness on off-road terrains. Taguchi’s L27 (33) orthogonal array was applied to analyze the specific wear rate as a response to three parameters—load, speed, and road roughness—separately for front and rear two-wheeler tires. Variation of hardness and wear pattern observation for the front and rear tires were carried out to oversee the surface deterioration. A numerical model based on abrasive grit-tire surface interaction was developed for comparison with the experimental results.
The European Company: Original expectations and deficiencies of implementation
Authors: Keller Berndt , Rosenbohm Sophie
Published: January 2019

We address the failures of the implementation of the European Company Directive and their far-reaching consequences, and discuss options for necessary amendments and improvements. We present empirical data on the characteristics of European companies and their distribution across EU Member States, and discuss major unexpected results of transposition and implementation as well as many evident problems. We then develop options for amendments, including definition of structural changes, mandatory introduction of employee involvement and extension of the ‘before and after’ principle. Finally, we analyse the history of the review process and explain why amendments have not and will most likely not be introduced despite obvious failures and deficiencies.
Environmental footprint of small-scale, historical mining and metallurgy in the Swedish boreal forest landscape: The Moshyttan blast furnace as microcosm
Authors: Myrstener Erik , Biester Harald , Bigler Christian , Lidberg William , Meyer-Jacob Carsten , Rydberg Johan , Bindler Richard
Published: January 2019

The history of mining and smelting and the associated pollution have been documented using lake sediments for decades, but the broader ecological implications are not well studied. We analyzed sediment profiles covering the past ~10,000 years from three lakes associated with an iron blast furnace in central Sweden, as an example of the many small-scale furnaces with historical roots in the medieval period. With a focus on long-term lake-water quality, we analyzed multiple proxies including geochemistry, pollen and charcoal, diatom composition and inferred pH, biogenic silica (bSi), visible near-infrared spectroscopy (VNIRS)-inferred lake-water total organic carbon (LW-TOC), and VNIRS-inferred sediment chlorophyll (sed-Chl). All three lakes had stable conditions during the middle Holocene (~5000 BCE to 1110 CE) typical of oligo-dystrophic lakes: pH 5.4–5.6, LW-TOC 15–18 mg L−1. The most important diatom taxa include, for example, Aulacoseira scalaris, Brachysira neoexilis, and Frustulia saxonica. From ~1150 CE, decreases in LW-TOC, bSi, and sed-Chl in all three lakes coincide with a suite of proxies indicating disturbance associated with local, small-scale agriculture, and the more widespread use of the landscape in the past (e.g. forest grazing, charcoal production). Most important was a decline in LW-TOC by 30–50% in the three lakes prior to the 20th century. In addition, the one lake (Fickeln) downstream of the smelter and main areas of cultivation experienced a shift in diatom composition (mainly increasing Asterionella formosa) and a 0.6 pH increase coinciding with increasing cereal pollen and signs of blast furnace activity. The pH did not change in the other two lakes in response to disturbance; however, these lakes show a slight increase (0.3–0.5 pH units) because of modern liming. LW-TOC has returned to background levels in the downstream lake and remains lower in the other two.

Published: January 2019

Background

Lupus nephritis (LN) is a major determinant of mortality in systemic lupus erythematosus (SLE). Here we evaluated the association between complete renal response (CR) and mortality in LN.

Methods

We retrospectively analyzed the cases of 172 of 201 patients with LN for whom data on the therapeutic response at 6 and 12 months after induction therapy were available. The patients underwent a renal biopsy at Nagasaki University Hospital and community hospitals in Nagasaki between the years 1990 and 2016. We determined the CR rates at 6 and 12 months after induction therapy initiation and evaluated the predictive factors for CR and their relationship with mortality. We performed univariate and multivariable competing risks regression analyses to determine the factors predictive of CR. The patients' survival data were analyzed by the Kaplan–Meier method with a log-rank test.

Results

The median follow-up duration after renal biopsy was 120 months (interquartile range: 60.3–191.8 months). The 5-, 10-, 15- and 20-year survival rates of our cohort were 99.3, 94.6, 92.0 and 85.4%, respectively. During follow-up, nine patients (5.2%) died from cardiovascular events, infection, malignancy and other causes. The multivariate analysis revealed that the following factors were predictive of CR. At 6 months: male gender (odds ratio (OR) 0.23, 95% confidence interval (CI) 0.08–0.65, p = 0.0028), proteinuria (g/gCr) (OR 0.83, 95% CI 0.71–0.97, p = 0.0098) and index of activity (0–24) (OR 0.84, 95% CI 0.71–0.99, p = 0.0382). At 12 months: male gender (OR 0.25, 95% CI 0.09–0.67, p = 0.0043) and index of activity (0–24) (OR 0.82, 95% CI 0.69–0.98, p = 0.0236). The Kaplan–Meier analysis showed that compared to not achieving CR at 12 months, achieving CR at 12 months was significantly correlated with the survival rate (OR 0.18, 95% CI 0.04–0.92, p = 0.0339).

Conclusions

Our results suggest that the survival rate of patients with LN is associated with the achievement of CR at 12 months after induction therapy, and that male gender and a higher index of activity (0–24) are the common predictive factors for failure to achieve CR at 6 and 12 months.
Targeting MicroRNA-21 Suppresses Gastric Cancer Cell Proliferation and Migration via PTEN/Akt Signaling Axis
Authors: Zhou Hao , Liu Hongyan , Jiang Miao , Zhang Shaoren , Chen Junfeng , Fan Xiaoming
Published: January 2019

MicroRNA plays a pivotal role in various human cancers, especially in human gastric cancer. In the present study, we evaluated the effect of microRNA-21 (miR-21) on the gastric cancer cell proliferation, migration, apoptosis and the related signaling cascades. Here, we showed that down-regulation of miR-21 markedly reduced gastric cancer cell proliferation (AGS and NCI-N87 cells) in a time dependent manner. Moreover, our findings revealed that silencing miR-21 dramatically blocked gastric cancer cell migration and movement, which might be related to down-regulation of vimentin expression. We also found that down-regulation of miR-21 promoted cell apoptosis and repressed cell cycle progression. Further investigation showed that down-regulation of miR-21 significantly increased phosphatase and tensin homolog (PTEN) protein expression level, but not transcription level (mRNA level), which in turn decreased Akt phosphorylation at Thr308 and Ser473. Collectively, our results uncover that miR-21 targets PTEN/Akt signaling pathway and regulates cell proliferation, migration and apoptosis in human gastric cancer cells. Our findings may provide a therapeutic target for treatment of human gastric cancer.

Published: January 2019

Despite the increase in methodological sophistication and complexity of models being tested for international student adjustment to universities in the United States (U.S.), researchers often do not test or control for salient demographic differences between students, including their educational status (i.e., graduate or undergraduate) and country in which they graduated high school. The current study was designed to examine whether demographic variables are associated with a range of social outcomes. Participants ( N = 245) from 23 U.S. colleges and universities completed a survey in Fall 2017. Undergraduate students reported having a higher number of close friends at their institution than did graduate students; however, they also reported a lower sense of belonging than did graduate students. Students who graduated from high school in the United States reported less social support from international students at university. Implications for students and for future research are provided.
Transnational Higher Education and the Factors Influencing Student Decision-Making: The Experience of an Irish University
Authors: Dowling-Hetherington Linda
Published: January 2019

Increasingly, universities have been engaging in transnational higher education (TNE), and such activity provides students with an additional study option. While much is already known about the TNE activities of universities in larger countries, such as Australia and the United Kingdom, very little is known about universities from smaller countries, such as Ireland. This article examines an Irish university with international branch campuses in Hong Kong, Singapore, and Sri Lanka. The results of a survey exploring the factors that influenced students’ choice of location, institution, and program and conducted among three cohorts of students over a 2-year period are presented. The results suggest that, above all other factors, the university’s international ranking and the accreditations and rankings of its Business School are particularly influential in students’ decision-making process. This finding highlights a potential exposure in terms of the scale of the institution’s student recruitment and revenue streams should it ever experience a decline in its rankings or international reputation.
Affordance-based altruistic robotic architecture for human–robot collaboration
Authors: Imre Mert , Oztop Erhan , Nagai Yukie , Ugur Emre
Published: January 2019

This article proposes a computational model for altruistic behavior, shows its implementation on a physical robot, and presents the results of human–robot interaction experiments conducted with the implemented system. Inspired from the sensorimotor mechanisms of the primate brain, object affordances are utilized for both intention estimation and action execution, in particular, to generate altruistic behavior. At the core of the model is the notion that sensorimotor systems developed for movement generation can be used to process the visual stimuli generated by actions of the others, infer the goals behind, and take the necessary actions to help achieving these goals, potentially leading to the emergence of altruistic behavior. Therefore, we argue that altruistic behavior is not necessarily a consequence of deliberate cognitive processing but may emerge through basic sensorimotor processes such as error minimization, that is, minimizing the difference between the observed and expected outcomes. In the model, affordances also play a key role by constraining the possible set of actions that an observed actor might be engaged in, enabling a fast and accurate intention inference. The model components are implemented on an upper-body humanoid robot. A set of experiments are conducted validating the workings of the components of the model, such as affordance extraction and task execution. Significantly, to assess how human partners interact with our altruistic model deployed robot, extensive experiments with naïve subjects are conducted. Our results indicate that the proposed computational model can explain emergent altruistic behavior in reference to its biological counterpart and moreover engage human partners to exploit this behavior when implemented on an anthropomorphic robot.
Evaluation of Rescue Thrombolysis in Cardiac Arrest Secondary to Suspected or Confirmed Pulmonary Embolism
Authors: Summers Katherine , Schultheis Jennifer , Raiff Doug , Dahhan Talal
Published: January 2019

Background: Pulmonary embolism (PE) is the associated cause of unexplained cardiac arrest in 5% to 13% of patients. Although thrombolytic agents have been studied, patient outcomes during cardiac arrest are lacking. Objective: The purpose of this study was to describe outcomes of patients who received thrombolytic therapy during cardiac arrest for suspected or confirmed PE. Methods: This retrospective review included adults who received alteplase or tenecteplase during cardiac arrest for suspected or confirmed PE. The primary end point was incidence of survival to hospital discharge, whereas secondary end points included a description of dosing strategies of thrombolytic therapy, the incidence of return of spontaneous circulation (ROSC), the occurrence of minor or major bleeding, and intensive care unit and hospital lengths of stay. Results: Of the 22 patients included in the study, 3 patients (13.6%) survived to hospital discharge, and ROSC was obtained in 11 patients (50%). Three patients had confirmed PE prior to cardiac arrest, with the remaining 19 patients having a documented suspicion for PE. The most frequent dosing strategy was alteplase 100 mg given via intravenous push (13 of 22 patients; 59%). One minor and no major bleeding events occurred. Conclusion and Relevance: Medical advances in PE management continue to evolve; yet the role of thrombolytic therapy in PE-related cardiac arrest remains unclear, with low overall rates of survival. These findings add to the relatively small body of evidence and highlight that optimal dosing remains unknown in this setting.
Underemployment and Meaningful Work: The Role of Psychological Needs
Authors: Kim Taewon , Allan Blake A.
Published: January 2019

Underemployment is a global problem that is increasing in the context of recovering economic recessions and insecure job markets. In this context, vocational psychologists can play a unique role by determining the processes by which underemployment relates to aspects of work well-being, such as meaningful work. Therefore, the goal of this study was to examine the relation between underemployment and meaningful work as well as to investigate potential mediators of this relation. Specifically, with a sample of 351 working adults in the United States, we investigated how underemployment related to the meaningful work via the self-determination needs of autonomy, competence, and relatedness. Partially supporting hypotheses, underemployment was negatively related to autonomy and relatedness but positively related to competence. In turn, autonomy and competence were positively related to meaningful work, whereas relatedness was unrelated to meaningful work. These results offer insights into how underemployment might affect the meaningfulness of work and how employers and practitioners can help underemployed workers.

Published: January 2019

Rita Levi-Montalcini was an extraordinary personality and with her profession she made a tremendous contribution to humanity. Doctor, Nobel laureate for medicine, neuroscientist, she contributed, thanks to her research, to improve the knowledge of the nervous system. She discovered the nerve growth factor, which is applied in various fields of neurology, concerning neurodegenerative diseases. She also studied, in relatively newer years, the mechanisms of neuroinflammation. This last is a research that has been developing in recent years and is based on the predominantly anti-inflammatory properties of endogenous substances that able to act not only on diseases of the nerves, neuropathies, on the nerve roots, and radiculopathies but also on migraine and other non-neurological diseases. Her long life was full of positive and negative events. Born in a Jewish family, she lived her life as a young woman through war, Nazi deportations, and the Holocaust. Despite the difficulties, she found time to do research in the medical field, organizing research laboratories with other scholars. She had a difficult life, interspread with pain, destruction, extermination of human beings but also rewarded by scientific discoveries. A “small” woman but a great neuroscientist.
Multimethod Assessment of Attention, Executive Functions, and Motor Skills in Children With and Without ADHD: Children’s Performance and Parents’ Perceptions
Authors: Bünger Anette , Urfer-Maurer Natalie , Grob Alexander
Published: January 2019

Objective: We examined whether children with attention-deficit/hyperactivity disorder (ADHD) differ from children without ADHD in attention, executive functions, and motor skills and whether measures of parents’ perceptions and children’s performance reveal comparable results. Method: About 52 children with ADHD and 52 children without ADHD aged 6 to 13 years completed performance-based measures of attention, executive functions, and motor skills. Parents completed questionnaires to rate their children’s skills. Results: Parent questionnaires but not performance-based measures revealed higher inattention and lower executive function skills in children with ADHD compared to controls. For motor skills, both measurement methods revealed lower mean values and a higher number of children showing an impairment in the ADHD group. Parent-reported difficulties but not performance-based measures were related to the presence of an ADHD diagnosis. Conclusion: Our findings suggest that considering both parent questionnaires and performance-based measures will lead to a comprehensive picture of a child’s strengths and difficulties.

Authors: Köseoglu Mehmet Ali , Okumus Fevzi , Putra Eka Diraksa , Yildiz Mehmet , Dogan Ismail Cagri
Published: January 2019

The purpose of this article is to analyze the conceptual structure of lodging-context research. In this regard, 2,632 articles published between 1990 and 2016 were analyzed utilizing network analyses. We find that the knowledge domain of lodging has been expanding, with greater focus on the business and economic activities of hotels. As the network density is low, lodging as a field is at a relatively early growth level and it is open for multidisciplinary collaborations. Articles related to strategy, marketing, and human resource management are relatively mature and well developed. However, some areas such as resource-based view, and cruise business still remain undeveloped and immature. Moreover, as one of the first studies in this field, this work provides an inclusive evaluation of the results, limitations, and suggestions for future research.
‘We are all herd animals’: Community and organizationality in coworking spaces
Authors: Blagoev Blagoy , Costas Jana , Kärreman Dan
Published: January 2019

This article develops an understanding of coworking spaces as organizational phenomena. Based on an ethnography of betahaus in Berlin, we demonstrate how coworking spaces not only provide a sense of community but also pattern the work activities of their members. We theorize this finding by drawing on the emergent literature on organizationality. Our contribution is twofold. First, we challenge current understandings of coworking spaces as neutral containers for independent work. Instead, we show how coworking incorporates the disposition of becoming organizational. That is, coworking spaces can frame and organize work and may even provide a basis for collective action. Second, we add to research on organizing outside traditional organizations by drawing attention to the complex and shifting interplay of formal and informal relationships in such settings. In doing so, we inform current debates about new forms of organization and organizing.
Regional integration and growth: New empirical evidence from WAEMU
Authors: Ogbuabor Jonathan E. , Anthony-Orji Onyinye I. , Ogbonna Oliver E. , Orji Anthony
Published: January 2019

This study provides a pioneer analysis of the growth effect of WAEMU integration at the econometric level, unlike the extant literature that relied on descriptive analysis of the sub-region’s trade statistics. The study used robust instrumental variables system GMM regression in the framework of a cross-country growth model and annual panel data for the period 2000 to 2015. Contrary to the widely held view that regional economic integration fosters economic growth of the participating countries, we did not find any empirical support for a positive growth impact of WAEMU integration in West Africa, which may be due to a variety of factors that mainly point to the characteristics of the WAEMU economies. However, the results indicate that foreign direct investment (FDI), institutional quality, capital, labour and the initial real per capita GDP are important drivers of growth in the sub-region. Interestingly, the results further indicate that FDI and institutional quality are the channels through which WAEMU integration may impact on growth in West Africa. The study therefore concludes that policy reforms towards improved institutions and increased FDIs will enhance economic growth in West Africa.
The future of capitalism: Trends, scenarios and prospects for the future
Authors: Delanty Gerard
Published: January 2019

The article provides a framework for thinking about how the question of the future of capitalism might be addressed. One of the problems resides in the very definition of capitalism and of what its defining features consist of and whether we should be talking about ‘capitalist society’ or the ‘capitalist economy’ or some kind of post-capitalist condition. Following Polanyi, Castoriadis and Habermas, it is argued that capitalism and democracy together constitute the defining dynamics of modernity and that the resulting tensions will provide momentum for the main circuits of potential change. Five scenarios for looking at the future are discussed. These will form the main substance of the article: varieties of capitalism, systemic crises of capitalism, catastrophic collapse, low growth capitalism and post-capitalism. In conclusion, it is argued that there are various possibilities that can be understood in terms of transitions, breakdown or transformation, but a likely future trend will be less the end of capitalism than the harnessing of ‘super-capitalism’ and that there are limits to the accumulation of capital.

He is the author of several books on Marx and Marxism, including The Young Hegelians and Karl Marx; Karl Marx: His Life and Thought; Karl Marx: Selected Writings; Marx before Marxism; and Marxism and Religion. He has also published a biography of Simone Weil, books on the political implications of Christianity, and a lengthy article on contract law and marriage. He lectures widely around the world on these topics, frequently in China, and in 2018 addressed a conference in Nairobi on religion and world peace. In this interview, or conversation, with Larry Ray and Iain Wilkinson, in July 2018, David discusses the origins of his interest in Marx, the development Marx’s thought and his critique of the Hegelians, Marx’s critical method, Marx and religion, Marx on Russia, the role of violence in social change, the relevance of Marx’s work today, and offers comments on some recent biographies. David has spent much of his intellectual career engaging with the meaning and legacy of Marxism and these reflections should generate reflection and debate on the significance of Marx and the possibilities of radical political change today.

Objectives. Distracted driving is a major public health issue in the United States. In response to requests from high school students participating in a university-based initiative, the authors describe the collaborative development and implementation of a curriculum designed to address distracted driving behaviors among students in four high-needs school districts in the northeastern United States. Method. The curriculum integrates current statistics on distracted and drowsy driving and three interactive learning stations: driving while distracted, walking while distracted, and driving while drowsy. Pre- and postsurveys were conducted to collect student driving data, assess student satisfaction with the program, and assess their likelihood of speaking up as a passenger in a high-risk situation. Results. The majority of students reported that they learned new information and would recommend the program to others. A Wilcoxon signed-rank test showed that students were more likely to speak up as a passenger with a distracted or drowsy driver (p < .001) after the program. Conclusion. This experience demonstrates a voluntary, multidisciplinary, university-based collaboration in the development of a novel public health education initiative. Based on the success of this phase, school districts elected to participate in Train the Trainer sessions to continue the program within their local high-needs school district.
The Visual Experience of Accessing Captioned Television and Digital Videos
Authors: Butler Janine
Published: January 2019

The increase in video-based communication has made different caption styles more apparent to audiences, including hearing viewers who watch social media videos with colorful open captions. To explore how viewers respond to a variety of caption styles, this article shares findings from three focus group discussions with twenty deaf and hard-of-hearing college students. This article begins by discussing the accessibility of captioned television and digital media and how captions can influence the viewing experience. This article then analyzes deaf and hard-of-hearing focus group participants’ statements about their viewing experiences, reception practices, and critiques of aesthetic and accessible caption styles. The analysis of viewers’ feedback reveals how the tension between various approaches to captions contributes to the reshaping of television and online media: a reshaping in which captions are coming to the forefront of the viewing experience for deaf, hard-of-hearing, and hearing viewers.
Caregiver Burden and Desire for Institutional Placement—The Roles of Positive Aspects of Caregiving and Religious Coping
Authors: Fields Noelle L. , Xu Ling , Miller Vivian J.
Published: January 2019

Based on stress coping theory, this study investigated whether and how positive aspects of caregiving (PAC) and religiosity buffered the association between caregiving burden and desire to institutionalize (DTI). Secondary data (N = 637) were drawn from the baseline assessment of the Resources for Enhancing Alzheimer’s Caregiver Health II project. Descriptive analysis, bivariate correlation, and multiple linear regressions were conducted. The results indicated that higher levels of caregiver burden, daily care bother, and Revised Memory and Behavioral Problem Checklist bother were all significantly associated with higher level of DTI. Both PAC and religious coping were negatively associated with DTI; however, only PAC was significant. Only the interaction between daily care bother and religious coping was significant, which indicated that the harmful effect of daily care bother on DTI was significantly buffered among those who have religiosity. Study findings have important implications for policy makers and for providers who serve dementia family caregivers.

Effect of Specific Over Nonspecific VR-Based Rehabilitation on Poststroke Motor Recovery: A Systematic Meta-analysis
Authors: Maier Martina , Rubio Ballester Belén , Duff Armin , Duarte Oller Esther , Verschure Paul F. M. J.
Published: January 2019

Background. Despite the rise of virtual reality (VR)-based interventions in stroke rehabilitation over the past decade, no consensus has been reached on its efficacy. This ostensibly puzzling outcome might not be that surprising given that VR is intrinsically neutral to its use—that is, an intervention is effective because of its ability to mobilize recovery mechanisms, not its technology. As VR systems specifically built for rehabilitation might capitalize better on the advantages of technology to implement neuroscientifically grounded protocols, they might be more effective than those designed for recreational gaming. Objective. We evaluate the efficacy of specific VR (SVR) and nonspecific VR (NSVR) systems for rehabilitating upper-limb function and activity after stroke. Methods. We conducted a systematic search for randomized controlled trials with adult stroke patients to analyze the effect of SVR or NSVR systems versus conventional therapy (CT). Results. We identified 30 studies including 1473 patients. SVR showed a significant impact on body function (standardized mean difference [SMD] = 0.23; 95% CI = 0.10 to 0.36; P = .0007) versus CT, whereas NSVR did not (SMD = 0.16; 95% CI = −0.14 to 0.47; P = .30). This result was replicated in activity measures. Conclusions. Our results suggest that SVR systems are more beneficial than CT for upper-limb recovery, whereas NSVR systems are not. Additionally, we identified 6 principles of neurorehabilitation that are shared across SVR systems and are possibly responsible for their positive effect. These findings may disambiguate the contradictory results found in the current literature.
Photochemical Tissue Bonding Technique for Improving Healing of Hand Tendon Injury

Published: January 2019

Purpose. We utilized a novel approach of combined photochemical tissue bonding (PTB) and human amniotic membrane (HAM) to improve hand tendon repair and also evaluated its efficacy. Methods. Subei chickens underwent surgical transection of the flexor digitorum profundus tendons and repair by (1) SR (standard Kessler suture; n = 24; 6-0 prolene) and (2) HAM/PTB (n = 24), where a section of HAM was stained with 0.1% Rose Bengal, wrapped around the ruptured tendon and bonded with 532 nm light (0.5 W/cm2, 200 J/cm2). Total active motion, gross appearance, extent of adhesion formation, biochemical properties, and inflammatory cells of the repaired tendon were evaluated on days 3, 7, 14, and 28 postoperatively. Results. PTB strongly bonded HAM with flexor digitorum profundus tendon surface. No significant difference was observed between the tensile properties of either group on all postoperative time points. The joint activities and the adhesion formation levels were significantly better in the HAM/PTB group compared with those in the SR group on day 14. Histological examination revealed drastically reduced number of inflammatory cells in the HAM/PTB group than in the SR group on days 7 and 14 after surgery. Conclusions. These findings revealed that PTB sealing of HAM around the tendon repair site provided considerable benefits for hand tendon repair by eliminating technical difficulties and obvious contraindications. Thus, this novel procedure has considerable benefits in repairing hand tendon damage.
