Retargeting: an unrecognized consideration in endonuclease-based gene drive biology
Authors: Scharenberg Andrew M. , Stoddard Barry L , Monnat Raymond J , Nolan Anthony 
Published: November 2016

AbstractThere is intense interest surrounding the use of gene editing nucleases in gene drive systems to control agricultural insect pests and insect vectors of infectious diseases such as malaria, dengue and Zika virus. While gene drive systems offer immense promise for the beneficial modification of deleterious insect populations, their unique mechanism of action also raises novel safety concerns and regulatory issues. A recent US National Academies of Science report provides a list of potential regulatory issues associated with implementation of homologous recombination (HR)-mediated gene drive systems, based on the premise that all such systems would exhibit similar biological behaviors. Here we examine how HR-mediated gene drive systems based on different gene editing nuclease platforms could be affected by mutations that occur during host cell transcription, genome replication, and, in conjunction with gene editing nuclease activity, during HR-mediated gene drive. Our analysis suggests that the same feature that makes RNA-guided nucleases such attractive research tools—their ease of reprogramming by alterations to their guide RNA components—might also contribute to increased rates of retargeting that could influence the long term behavior of RNA-guided gene drive systems. Predictability of behavior over time is an issue that should be addressed by in-depth risk assessment before field testing of organisms incorporating nuclease-mediated gene drives.
A way to increase K-SURE’s export insurance recoveries through arbitration by subrogation
Authors: Ahn Keon-Hyung , Kim Pil-Joon 
Published: November 2016

Purpose
The purpose of this paper is to utilize the concept of arbitration by subrogation as a means to increase recoveries of indemnities paid out to exporters or any financial institutions by K-SURE, an export credit agency of Korea, against possible non-payment or breach of obligations from the buyer or the buyer’s country. It looks into the possibility of K-SURE and KCAB reactivating its 2004 MOU to give more jurisdictional protection to K-SURE’s indemnities recovery transactions.

Design/methodology/approach
This paper first introduces a brief elucidation about export insurance provided by K-SURE and the necessity of arbitration in the export insurance, and a summary of a subrogation arbitration case referred to the KCAB by K-SURE in 2005. Cognizant of the 2004 MOU between K-SURE and KCAB, as well as the foreign and domestic developments in arbitration, the paper then analyzes legal principles of subrogation by insurer, as well as domestic and overseas precedents on the matters of assignment of claim and arbitration by subrogation.

Findings
While it appears that there is still no universally recognized authority nor established court precedents applying arbitration by subrogation, the authors discovered that similar to Korea, most of leading courts in the world have consistently held that the assignee can request and be requested for arbitration pursuant to the arbitration agreement contained in the assigned contract. The paper concludes that the K-SURE now can be admitted as a party having proper standing in the arbitration proceedings so long as the specific claim right under the contract which includes the arbitration agreement is assigned to the K-SURE.

Originality/value
This paper suggests a possible plan to increase recoveries in export insurance. The outcome of the research is expected to enhance the arbitration system on the back of increasing numbers of arbitration related to export insurance, to improve the balance sheet of K-SURE and ultimately, to help the Korean economy by collecting export insurance recoveries which will lead to saving Korean people’s tax.
Struggles in the WTO’s dispute settlement procedures: focused on the US power dominance
Authors: Kwon Youngmin 
Published: November 2016

Purpose
The purpose of this paper is to investigate differences among member groups, with more detailed division of groups than the existing literatures, during the WTO’s dispute settlement procedures.

Design/methodology/approach
Trade disputes requested through the WTO’s DSU regimes up until 2011 were statistically described and analyzed using logit regression models.

Findings
Despite capacity gaps, developing nations have encountered stronger legal challenges from the US and, although without much capacity gaps, similar patterns of litigation rivalries between the US and other advanced countries, with the exception of the EU, have been also found during dispute settlements in the WTO regimes.

Research limitations/implications
Although the DSU procedures themselves might not be biased for/against certain member groups, there has been some evidence of the struggles of weaker opponent groups of the US during the actual litigation processes.

Originality/value
Power dominances of the US against developing nations as well as developed nations, other than the EU, have been neglected in many previous researches on the topic with a simple developed-developing dichotomy classification.
Supply chain information sharing: challenges and risk mitigation strategies
Authors: Huong Tran Thi Thanh , Childerhouse Paul , Deakins Eric 
Published: November 2016

Purpose
The purpose of this paper is to investigate how managers perceive risks associated with sharing information with trading partners, and how they attempt to mitigate them.

Design/methodology/approach
In this exploratory New Zealand study, qualitative research was conducted involving semi-structured interviews with boundary spanning managers who are responsible for inter-organizational interfaces. Multiple case studies in different industries are used to highlight managers’ perceptions of risks in data exchange process throughout the supply network, and their underlying reasoning.

Findings
Managers perceive several types of risks when exchanging information across external supply chain interfaces, and adopt different approaches to handling them. The research also reinforces the vital role played by interpersonal relationships and trust as key enablers of inter-organizational cooperation.

Research limitations/implications
The findings are based on a small sample of 11 case companies based in a single New Zealand province, thereby potentially restricting generalizability. Future work could usefully extend the sample size in order to investigate the correlations between firm sizes, levels of trust, and degrees of data integration within particular industry sectors.

Practical implications
The findings will help managers understand and evaluate different types of risks in the data exchange process, and enable them to make better decisions that enhance information sharing and supply chain performance.

Originality/value
Perceived information sharing risks are peculiar to the individual actors, and as such need to be mitigated through changes to their socially constructed perceptions. This work extends the literature on understanding the various dimensions of inter-organizational information sharing.
Audit committee impact on the quality of financial reporting and disclosure
Authors: Salehi Mahdi , Shirazi Mohammadamin 
Published: November 2016

Purpose
The purpose of this study is to shed further light on the characteristics of an audit committee (AC) and its probable relationship with the quality of financial reporting and disclosure. Based on the findings of extant research that there are different factors that may have implications for the AC’ effectiveness, the authors posit an association between the aforementioned financial aspects and AC presence.

Design/methodology/approach
The authors test their hypotheses by performing panel data analysis on a sample of 100 companies listed on the Tehran Stock Exchange (TSE) during 2013-2014. The tests were conducted by using Eviews software.

Findings
Examining previously tested characteristics of an AC, the authors indicate that the number of AC meetings held during fiscal year is negatively associated with the quality of corporate disclosure, whereas AC expertise and size are positively associated with the quality firm’s financial disclosure. Their findings are also indicative of a non-significant relationship between other AC attributes and financial reporting quality (FRQ) except for AC independence, which is positively associated with FRQ. Finally, they provide some evidence that the size of a firm positively affects the quality of its financial reporting and disclosure.

Research limitations/implications
Although the study has been thoroughly considered and cautiously planned, some limitations have yet arisen. Initially, this research was conducted in an Iranian setting where the formation of ACs is on the verge of regulation; therefore, the data utilized for the study only contains the two-year period of ACs’ statutory activity. In addition, a lack of consensus on the precise measures of an AC’s effectiveness could be considered as a restrictive factor.

Originality/value
The authors’ study contributes to the AC literature by providing empirical evidence of an association between ACs’ different attributes and financial aspects in a newly regulated environment like the TSE. The results provided in this paper could be fruitful for auditors, regulators, institutional investors and policymakers.
Job satisfaction and organizational commitment
Authors: Valaei Naser , Rezaei Sajad 
Published: November 2016

PurposeThe aim of this study is to examine the structural relationship between Spector’s nine job satisfaction facets (supervision, nature of the work, communication, contingent rewards, co-worker, fringe benefits, payment, promotion and operating procedures), organizational commitment facets (normative commitment, affective commitment and continuance commitment) and the influence of employees’ years of experience on satisfaction and commitment relationships. Owing to the nature of the industry, employee satisfaction, retention and commitment in Information and Communications Technology-Small and Medium-sized Enterprise (ICT-SME) is a matter of great concern.Design/methodology/approachA total of 256 valid questionnaires were collected among employees of Information and Communications Technology-Small and Medium-sized Enterprises (ICT-SMEs) to evaluate the measurement and structural model using partial least squares path modelling approach.FindingsThe findings indicate that payment, promotion, fringe benefits, co-worker, communication, operating procedures and nature of the work are positively associated with affective commitment. Furthermore, payment, promotion, fringe benefits, supervision, contingent rewards, operating procedures and nature of the work have a positive relationship with normative commitment. Considering employees’ years of experience as a categorical moderating variable, the results of partial least squares multi-group analysis show how the discrepancies between employees’ years of experience influence their level of commitment.Originality/valueThis study reveals that employees’ affective and normative commitments are positively associated and their continuance commitment is contingent upon their affective commitment, and not normative commitment. There are only three factors, i.e. promotion, fringe benefits and operating procedures, that are conductive to employees’ continuance commitment. Contributions, implications and limitations of the study are discussed.
Exploring the facilitators and mediators of workforce agility: an empirical study
Authors: Muduli Ashutosh 
Published: November 2016

Purpose
Recognizing that very less number of research has been conducted on workforce agility, the current research aimed to examine the impact of organizational practices in the form of organizational learning and training, compensation, involvement, team work and information system (IS) on workforce agility. Influenced by the “Black Box” approach, the study also examined the role of psychological empowerment as a mechanism mediating the relationship between organizational practices and workforce agility.

Design/methodology/approach
The study has been conducted in selective Indian industries, representing manufacturing and service sector across public and private sectors. Quantitative and qualitative data have been collected from both executives and non-executives through reliable instruments validated in Indian context. Data have been analyzed using descriptive analysis, canonical correlation analysis and multiple regression.

Findings
Findings that organizational practices significantly related to workforce agility prove that organizational practices are capable of improving the agile attributes and behavior of the workforce. In detail, team work has the greatest influence on workforce agility, followed by Reward system, employee involvement, organizational learning and training and ISs. Further, the study result also proved the mediating role of psychological empowerment between organizational practices and workforce agility.

Practical implications
Organizations are to design practices related to organizational learning and training, compensation, involvement, team work and IS and implement them efficiently and effectively to enable agility within the workforce, as an agile workforce can only respond proactively to a volatile, uncertain, complex and ambiguous business environment. Further, the result also suggests that managers should design the organizational practices capable of enhancing psychological empowerment, as the combination can deliver better workforce agility.

Originality/value
The research is useful considering very less number of research on workforce agility.

Authors: Tumbare Michael J. , Makwarimba Peter 
Published: November 2016

Purpose
The purpose of this paper is to communicate and share experiences with other dam designers, operators and maintenance officers arising from the rehabilitation of the Osborne Dam outlets, pursuant to informing future dam outlet designs and rehabilitation of similar dam outlets.

Design/methodology/approach
This paper documents and utilizes actual events that occurred before and during the rehabilitation of the outlets. Some solutions applied were unique, with resultant innovative engineering designs being decided on site. Realizing that a descriptive research format would best serve the sharing of experiences of the outlets’ rehabilitation, the case study approach was selected. Before commencement of the rehabilitation works, the different operational problems that had been identified, photographed and documented by the dam’s operating staff were verified by the dam owner’s engineers, technicians and consultants. Visual and photographic verification was done using divers for areas under water. Literature review was conducted so as to learn from solutions employed elsewhere. A physical model of the solution considered the best way to keep the intake tower dry was made and tested.

Findings
The outlets’ rehabilitation works, taking 12 months to complete at a total cost of US$5 million, involved installation of new service gates, replacement of the sleeve valves, refurbishment of the butterfly valves and provision of dewatering pumps.

Originality/value
This paper offers unique experiences and lessons for dam designers and other dam operation and maintenance officers while contributing to the body of knowledge of outlet works rehabilitation.

Online Disaster Management: Applicability of the European Data Protection Framework and Its Key Principles
Authors: Jasmontaite Lina , Dimitrova Diana 
Published: November 2016

AbstractThe availability of applications that could be used by first responders and citizens in emergency situations has been constantly increasing over the past years. This trend is predetermined by the fact that various applications facilitate situational awareness and optimize data exchange between multiple actors. Yet the use of new technologies should be considered in the context of the applicable legal framework. Therefore, in this contribution, we discuss the applicability of the European data protection framework and its key principles related to online disaster management, and in particular, the processing of personal data when responding to disasters. The contribution provides examples of issues arising from the use of mobile apps.
