Broadband unidirectional behavior of electromagnetic waves based on transformation optics
Authors: Zang XiaoFei , Zhu YiMing , Ji XueBin , Chen Lin , Hu Qing , Zhuang SongLin 
Published: January 2017

AbstractHigh directive antennas are fundamental elements for microwave communication and information processing. Here, inspired by the method of transformation optics, we propose and demonstrate a transformation medium to control the transmission path of a point source, resulting in the unidirectional behavior of electromagnetic waves (directional emitter) without any reflectors. The network of inductor-capacitor transmission lines is designed to experimentally realize the transformation medium. Furthermore, the designed device can work in a broadband frequency range. The unidirectional-manner-based device demonstrated in this work will be an important step forward in developing a new type of directive antennas.

Published: January 2017

AbstractGallium-based Ga–Sb–S sulfide glasses was elaborated and studied. A relationship between the structure, composition, and optical properties of the glass has been established. The effects of the introduction of Ga on the structure using infrared and Raman spectroscopies and on the Er3+-doped IR emission have been discussed. The results show that incorporation of Ga induced the dissociation of [SbS3] pyramids units and the formation of tetrahedral [GaS4] units. The dissolved rare earth ions are separated around the Ga–S bonding and the infrared emission quenching are controlled. Moreover, continuous introduction of Er ions into the glass forms more Er–S bonds through the further aggregation surrounding the [GaS4] units. In return, the infrared emission intensity decreased with excessive Er ion addition. This phenomenon is correlated with the recurrence concentration quenching effect induced by the increase of [GaS4] units.
UNUSUAL SEROUS RETINAL DETACHMENT IN A PATIENT WITH WALDENSTROM MACROGLOBULINEMIA: A CASE REPORT
Authors: Lin Albert B. , Sheyman Alan T. , Jampol Lee M. 
Published: January 2017

Background/Purpose:
To report an unusual appearance of severe bilateral serous detachments in a patient with Waldenstrom macroglobulinemia.

Methods:
A case report of a Fifty-six–year-old female patient with Waldenstrom macroglobulinemia.

Results:
A patient with Waldenstrom macroglobulinemia presented with serous retinal detachments at the time of diagnosis with Waldenstrom. The patient's IgM levels remained abnormally elevated in the initial stages of her disease course, leading to dramatic ocular findings and images on optical coherence tomography. Chemotherapy was initiated and IgM levels slowly declined, with some improvement in macular fluid as IgM normalized.

Conclusion:
Waldenstrom macroglobulinemia may lead to dramatic retinal pathology if IgM levels remain elevated. Prompt chemotherapy and reduction of immunoglobulin levels should be undertaken to preserve retinal architecture.
Mutation of a palmitoyltransferase ZDHHC18-like gene is responsible for the minute wing mutation in the silkworm (Bombyx mori)

Published: January 2017

AbstractPulpal- and adult-stage minute wing (mw) mutants of the silkwormBombyx morihave much smaller wings than those of the wild type. Herein, we report the genetic and molecular mechanisms underling the formation of the minute wing. Fine mapping and positional cloning revealed that a palmitoyltransferaseZDHHC18-likegene (BmAPP）was responsible for themwmutation. CRISPR/Cas9 screening of theBmAPPgene in wild-type embryos revealed that a significant proportion of adults had themwmutation. In anmwmutant strain, u11, a 10-bp insertion in the promoter of a novel gene resulted in low-level translation of a protein belonging to the DHHC family. A PiggyBac-based transgenic analysis showed that the promoter induced the expression of aBmAPPgene promoter in the wild type but not themwmutant. These findings indicate that functional deletion of this gene promoter accounts for themwmutation in silkworm. The possibility thatBmAPPgene is involved in Hippo signalling pathway, an evolutionarily conserved signaling pathway that controls organ size, is discussed.
Employability and job search behavior
Authors: Yizhong Xie , Lin Zhibin , Baranchenko Yevhen , Lau Chi Keung , Yukhanaev Andrey , Lu Hailing 
Published: January 2017

PurposeGraduate employability is a key concern for many observers particularly at a time when education is increasingly available for the masses. The purpose of this paper is to examine the impact of graduate perceived employability on job search by integrating theory of planned behavior and to identify how job search self-efficacy, subjective norms, intention and intensity change over time.Design/methodology/approachData were collected from a six-wave survey study with a sample of Chinese university graduating students.FindingsResults show that perceived employability has a positive and significant effect on job search self-efficacy, attitude, intention and intensity; and that all the repeated measuring variables (except job search attitude) decreased over time.Practical implicationsThe study is useful for educators, employers and prospective students. It prompts discussion of reforms in the curriculum to increase graduate awareness of the complexity of the job search process and existing opportunities. The study could also help to explain how job search behavior changes over time.Originality/valueThe findings carry implications for both higher education research and the measures of improving graduate employability. The study fills the gap in the literature by integrating employability and the theory of planned behavior into one framework in order to analyze the process of Chinese university graduates’ job search behavior.
Customers’ perceived website service quality and its effects on e-loyalty
Authors: Jeon Myunghee Mindy , Jeong Miyoung 
Published: January 2017

Purpose
This study aims to examine determinants of perceived website quality and associations among consequences of perceived website quality. Adopting the framework of loyalty development, causal links are investigated among the website quality, customers’ perceived service quality, their satisfaction, return intention and loyalty in the context of the lodging industry.

Design/methodology/approach
An online field survey is conducted with internet bookers. A confirmatory factor analysis and a parameter estimate analysis using structural equation modeling are adopted to analyze the data.

Findings
The progression of the phases of loyalty proceeds in a linear fashion on a lodging website. Mediation effects of customer satisfaction and return intention are detected. Moderation effects of gender were also detected in the relationships among website service quality and consequences of website service quality.

Research limitations/implications
Caution is advised in generalizing findings of this study due to convenience sampling, although findings of the study do confirm results of previously conducted studies.

Practical implications
This study provides practical tips for website development for hospitality management to understand the e-loyalty formation process so that appropriate marketing strategies can be established to accommodate the type and degree of individual customer’s loyalty as well as gender-specific expectations from prospective customers.

Originality/value
This study demonstrates that customer loyalty formation in both physical and online environments has identical processes in the context of the lodging industry. The male group, compared to the female group, appears to be more sensitive in perceiving the effects of functionality of a lodging website, tends to develop customer satisfaction when perceiving website service quality and inclines to develop customer loyalty when having return intention.
Mediation of job embeddedness and satisfaction in the relationship between task characteristics and turnover
Authors: Ferreira Aristides I. , Martinez Luis F. , Lamelas José Pereira , Rodrigues Rosa I. 
Published: January 2017

PurposeEmployees’ turnover intention is a key problem that hotel managers face daily. This is partially explained by the inevitability of performing tasks with little significance and low identity. This study aims to understand how job embeddedness and job satisfaction could lessen the undesirable effect of task characteristics on turnover intentions.Design/methodology/approachA sample of 525 employees operating in 46 Portuguese hotels was used in this study. The questionnaire included demographic variables and four reliable instruments used to measure job satisfaction, job characteristics, job embeddedness and turnover intentions. The study used a multilevel statistical approach considering both the individual and the hotel levels of analysis.FindingsThrough multilevel statistics, the findings suggest that both at the individual level and the hotel level of analysis, job satisfaction and job embeddedness fully mediated the relationship between different task characteristics (significance and identity) and turnover intentions.Research limitations/implicationsDespite a possible absence of common method variance, due to the confirmatory factor analysis, social desirability bias may exist because of the self-reported nature of the survey.Practical implicationsManagers should increase the perceived costs of employees leaving the hotel by introducing training programs and plans for career development. Also, to increase job embeddedness, managers should also rethink the organizational dynamics of this industry.Originality/valueThis research provides empirical evidence of the antecedents and mediators of employees’ intentions to leave the hotel industry both at the individual and at the hotel level (multilevel approach).

Authors: Vasudev Kamini , Lamoure Joel , Beyaert Michael , Dua Varinder , Dixon David , Eadie Jason , Husarewych Larissa , Dhir Ragu , Takhar Jatinder 
Published: January 2017

Purpose
Research has shown that academic detailing (AD), which includes repeated in-person educational messages in an interactive format in a physician’s office, is among the most effective continuing medical education (CME) forms for improving prescribing practices and reducing drug costs. The purpose of this paper is to investigate AD’s feasibility and acceptability as an educational tool among psychiatrists and its ability to facilitate positive changes in antipsychotic prescribing.

Design/methodology/approach
All psychiatrists practicing in Southwestern Ontario, Canada were invited to participate. Participants (32/299(10.7 percent)) were provided with two educational sessions by a healthcare professional. Participants evaluated their AD visits and completed a pre- and post-AD questionnaire measuring various prescribing practice aspects.

Findings
A total of 26 out of 32 (81.3 percent) participants completed the post-AD evaluation; most of them (61.5 percent, n=16) felt that AD gave noteworthy information on tools for monitoring side-effects and 50.0 percent (n=13) endorsed using these in practice. In total, 13 participants (50.0 percent) felt that the AD sessions gave them helpful information on tools for documenting polypharmacy use, which 46.2 percent (n=12) indicated they would implement in their practice. No significant differences were found between participants’ pre- and post-assessment prescribing behaviors.

Practical implications
There is great need for raising AD program’s awareness and improving physician engagement in this process locally, provincially and nationally.

Originality/value
To the authors’ knowledge, this is the first AD program in Canada to target specialists solely. Participant psychiatrists accepted the AD intervention and perceived it as a feasible CME method.
Institutional sustainable purchasing priorities
Authors: Pullman Madeleine , Wikoff Robin 
Published: January 2017

Purpose
This purpose of this paper is to understand the environmental impacts of stakeholder-driven sustainable purchasing policies in institutional settings.

Design/methodology/approach
The research is framed using stakeholder and life cycle assessment (LCA) theories. The study uses a multi-method approach. Starting with interviews to understand the breadth of sustainability issues and significant food purchases facing institutional purchasing managers, the authors subsequently perform LCA of these various policies using the most popular food item in different categories.

Findings
From the interview results, the authors found that food purchasers focus predominately on cost, thus, are committed to food and packaging reduction. They are driven to buy local foods based on their consumer stakeholders but share their commitment to buying local products if the cost is appropriate. In the LCA of popular food items in multiple scenarios, avoiding food waste of various forms had significantly higher carbon emissions savings than packaging reduction or transportation minimizing (buy local) strategies.

Research limitations/implications
The sample relied solely on the perceptions of institutional purchasing managers in university dining services. Future research should involve collecting data from other stakeholder groups such as the customers themselves, institutional leaders, and in other types of institutional settings such as hospitals and government agencies.

Practical implications
The research provides managers with insights concerning the trade-offs between different sustainability objectives. In particular, findings show that reducing waste related animal protein has a bigger impact on environmental performance than many other popular sustainability objectives such as buying local or reducing packaging waste.

Social implications
The paper focuses on the purchasing trade-offs of buying local vs national food products, different packaging solutions, and food waste generation. These decisions offer some social benefits (improve the economic situation for local farms vs consolidated food producers) as well as multiple environmental benefits.

Originality/value
The paper presents new findings on the sustainability purchasing priorities of stakeholders in institutional food settings and subsequent LCA of those policies to show which might have the most environmental impact.
Variables affecting the market demand of sport lottery sales in China
Authors: Zhou Liangjun , Zhang James J. 
Published: January 2017

PurposeThe purpose of this paper is to examine the market demand of sport lottery in China from the following perspectives: available types and varieties of sport lottery, number of retail outlets, public welfare funds, promotion costs, per capita income, and population.Design/methodology/approachAs the earliest province of issuing the sales of sport lottery and having one of the largest sales volumes in China, Guangdong Province was chosen for conducting the current study. Data were obtained from 14 sport lottery administration and distribution centers and statistics bureaus of 14 corresponding municipal cities. Multiple regression analysis was used.FindingsMultiple regression analyses revealed that number of retail outlets, promotion cost, per capita income, and public welfare funds were positively (p<0.05) predictive of sport lottery sales; however, available types and varieties of sport lottery were not found to be significantly (p>0.05) related to total sport lottery sales. The findings are discussed in the context of theories and practices in the marketing and administration of sport lottery sales in China.Research limitations/implicationsSimilar studies are suggested to be conducted in provinces and regions beyond Guangdong Province.Originality/valueThis study combined socioeconomic characteristics of the population, lottery game characteristics and management factors for the first time.
Innovation for development and poverty reduction: an integrative literature review
Authors: Pansera Mario , Martinez Fabien 
Published: January 2017

PurposeThe purpose of this paper is to develop a critical analysis of the innovation discourse, arguing that a more contextualised understanding of the challenges of innovation for development and poverty reduction in low-income economies will help the authors’ to unravel new development opportunities and provide alternatives to conventional capitalist paths to innovation.Design/methodology/approachThe authors offer an integrative review of the literature addressing the topic of innovation emerging from within developing countries. Because existing innovation models are generally presented in ways that reflect practices and thought patterns inherent to the industrialised world, a literature review that offers an initial conceptualisation and synthesis of the literature to date on the theme of innovation from within developing countries provides for a more valuable contribution than a reconceptualization of existing models.FindingsThe paper highlights different narratives of innovation, how they emerge and what are their implications. The authors outline a research agenda for generating new knowledge about innovation capabilities in what is generally known as the developing world.Originality/valueThis paper shows that the recent evolution of the discourse of development is increasingly intertwined with elements that originated in other discursive worlds. The last three decades of innovation research have been characterised by a “cross-pollination” between different disciplines: development studies, science and technology studies, business management and organisation studies. By reviewing major research works conducted by scholars in these disciplines, this paper weds literature that heretofore have remained largely isolated from each other. The key innovation narratives that the study unveils – e.g. inclusive growth, bottom of the pyramid, grassroots innovation – address major questions of concern to these academic scholars around the political and socio-technical aspects that influence a firm’s capacity to innovate in the context of developing countries.
Should pharmaceutical companies engage in corporate social responsibility?
Authors: Min Maung , Desmoulins-Lebeault Francois , Esposito Mark 
Published: January 2017

PurposeThe purpose of this paper is to investigate whether corporate social responsibility (CSR) really adds value to corporate financial performance (CFP) in the pharmaceutical industry. Most pharmaceutical companies currently practice CSR by taking a “triple bottom line” approach of environmental, social, and economic strategies to manage their businesses and produce an overall positive impact.Design/methodology/approachA survey was developed based on professional experience, Carroll’s construct, the study’s hypotheses, and industry studies. The survey, composed of 45 questions using a seven-point Likert scale, was conducted among pharmaceutical professionals to evaluate whether CSR affects performance. Responses totaling 140, including 20 companies, were coded, taking into account the respondent’s corporate position and firm size.FindingsSurvey respondents strongly agreed that CSR adds value to CFP and should be viewed as a long-term investment. CSR programs should be implemented regardless of company size. CSR is effective because it invests in stakeholder management, such as with customers, government, investors, and activists, creating positive relationships which improve reputation and profitability.Research limitations/implicationsThis perception study shows the need for further quantitative analysis of CSR and CFP metrics specific to the pharmaceutical industry.Practical implicationsCSR programs should be implemented regardless of company size, and sheer size does not dictate whether CSR programs can be successful. This paper also sheds light on potential managerial implications that originate from these findings that may help pharmaceutical companies manage their scarce resources more effectively.Social implicationsIn today’s competitive economic environment, where increasingly stakeholders including investors scrutinize pharmaceutical firms’ environmental and social performance, CSR is a crucial strategy. The findings can help corporate managers make strategic CSR decisions to optimize benefits for their organization.Originality/valueWhile numerous studies have addressed the link between CSR and corporate performance across industries, definitive studies have not examined the pharmaceutical industry.
A comparison of cognitive flexibility and metalinguistic skills in adult good and poor comprehenders
Authors: Cartwright Kelly B. , Bock Allison M. , Coppage Elizabeth A. , Hodgkiss Melinda D. , Nelson Marisa Isaac 
Published: January 2017

Good and poor comprehenders exhibit different profiles of cognitive abilities, despite comparable decoding skills. Recent work suggests that executive functions, particularly cognitive flexibility, may underlie poor comprehenders' difficulties in childhood and adulthood. However, metalinguistic skills that enable readers to reflect on various aspects of print may also contribute to poor comprehenders' difficulties. We examined metalinguistic abilities (graphophonemic and syntactic) and cognitive flexibility (graphophonological–semantic and syntactic–semantic) in 24 good and 24 poor adult comprehenders, matched on age‐appropriate non‐word decoding skill and general cognitive ability. Groups differed significantly on graphophonemic awareness, syntactic awareness, and both measures of cognitive flexibility after verbal ability and word identification were controlled. Differences in cognitive flexibility remained significant even when relevant metacognitive skills were controlled. These data demonstrate additional cognitive differences between good and poor comprehenders that can inform theory and practice.What is already known about this topic:

Deficits in executive functions contribute to poor comprehenders' difficulties in childhood and adulthood.
Child and adolescent poor comprehenders are also lower in metalinguistic skills.
What this paper adds:

Adult good and poor comprehenders, matched on general cognitive ability and age‐appropriate non‐word decoding, differed significantly on syntactic and graphophonemic awareness, even when verbal ability and word identification were controlled.
Groups also differed significantly on cognitive flexibility, even when verbal ability and word identification were controlled.
Good and poor comprehenders' differences in cognitive flexibility remained significant when metalinguistic awareness was controlled; however, differences in metalinguistic awareness were attenuated when cognitive flexibility was controlled.
Implications for theory, policy, or practice:

Findings underscore the importance of metalinguistic awareness and executive functions, particularly cognitive flexibility, to understanding adult poor comprehenders' difficulties.
Findings suggest that models of reading comprehension, such as the simple view, should be adjusted to include variables, like cognitive flexibility, that contribute to comprehension beyond decoding and verbal ability.
Findings may have clinical utility for identification of poor comprehenders because cognitive flexibility can easily be assessed with brief measures.
