AbstractIn addition to acting as photoprotective compounds, carotenoids also serve as precursors in the biosynthesis of several phytohormones and proposed regulatory signals. Here, we report a signaling process derived from carotenoids that regulates early chloroplast and leaf development. Biosynthesis of the signal depends on ζ-carotene desaturase activity encoded by the ζ-CAROTENE DESATURASE (ZDS)/CHLOROPLAST BIOGENESIS5 (CLB5) gene in Arabidopsis thaliana. Unlike other carotenoid-deficient plants, zds/clb5 mutant alleles display profound alterations in leaf morphology and cellular differentiation as well as altered expression of many plastid- and nucleus-encoded genes. The leaf developmental phenotypes and gene expression alterations of zds/clb5/spc1/pde181 plants are rescued by inhibitors or mutations of phytoene desaturase, demonstrating that phytofluene and/or ζ-carotene are substrates for an unidentified signaling molecule. Our work further demonstrates that this signal is an apocarotenoid whose synthesis requires the activity of the carotenoid cleavage dioxygenase CCD4.

Abstract
High salinity causes growth inhibition and shoot bleaching in plants that do not tolerate high salt (glycophytes), including most crops. The molecules affected directly by salt and linking the extracellular stimulus to intracellular responses remain largely unknown. Here, we demonstrate that rice (Oryza sativa) Salt Intolerance 1 (SIT1), a lectin receptor-like kinase expressed mainly in root epidermal cells, mediates salt sensitivity. NaCl rapidly activates SIT1, and in the presence of salt, as SIT1 kinase activity increased, plant survival decreased. Rice MPK3 and MPK6 function as the downstream effectors of SIT1. SIT1 phosphorylates MPK3 and 6, and their activation by salt requires SIT1. SIT1 mediates ethylene production and salt-induced ethylene signaling. SIT1 promotes accumulation of reactive oxygen species (ROS), leading to growth inhibition and plant death under salt stress, which occurred in an MPK3/6- and ethylene signaling-dependent manner in Arabidopsis thaliana. Our findings demonstrate the existence of a SIT1-MPK3/6 cascade that mediates salt sensitivity by affecting ROS and ethylene homeostasis and signaling. These results provide important information for engineering salt-tolerant crops.
Weaving a web of control
Authors: Ladva Puja , Andrew Jane 
Published: June 2014

Purpose– The purpose of this paper is to explore the relationship between management controls and the work-life balance (WLB) of junior accountants working in four multinational accounting firms using semi-structured interviews.Design/methodology/approach– The authors interviewed junior accountants, asking them about their firms’ time budgeting process, their views on organisational culture and their experience of WLB.Findings– Time budgeting controls and the dominant discourses of “efficiency” and “career” form a web of control within these firms that sustain the long-hours culture. Drawing on the work of Foucault, the authors argue that the web of control is particularly strong because it is not imposed externally by a clearly identifiable source of power. Instead, the interviews revealed how junior accountants actively produce the web of control in order to secure their identity. This is particularly apparent when they speak of their career.Research limitations/implications– This research sheds light on the relationship between management controls and WLB. Management controls are effective in large multinational accounting firms because they work through the emergent identity of young professionals.Originality/value– The link between management control systems and WLB has received little attention from accounting academics. This research offers important insights into the way management control systems and organisational culture may impact the lived experience of WLB within multinational accounting firms.
The rise and fall of the UK operating and financial review
Authors: Rowbottom N. , Schroeder M.A.S. 
Published: June 2014

Purpose– The purpose of this paper is to analyse the controversial repeal of legislation requiring UK companies to disclose an Operating and Financial Review (OFR). After a lengthy period of consultation and the preparation of a reporting standard, legislation was passed in March 2005 requiring UK listed companies to disclose a separate statement of management commentary, an OFR. In November 2005 the Chancellor unexpectedly and controversially announced the repeal of the OFR during a speech to the largest business lobbying group in the UK.Design/methodology/approach– The analysis draws upon internal, private governmental documents prepared by the Treasury ministry to brief the Chancellor, publicly disclosed as a result of a legal challenge against the repeal decision.Findings– The paper describes how Treasury officials were motivated to seek deregulatory opportunities in order to gain political support for their head, Prime Minister-in-waiting, Gordon Brown. The analysis reveals how the repeal of the OFR was identified as an example of corporate deregulation, and how this perception proved to be misplaced following the reaction to the repeal decision which led to the government reinstating many OFR requirements in an enhanced Business Review in 2006.Originality/value– The paper draws on the conception of “3-D” power to analyse how a political ideology prevalent in the pre-financial crisis environment came to influence accounting technology with unexpected consequences. Using data rarely disclosed in the public domain, it illuminates the “black boxed” processes underlying regulatory decision making. The paper details how the Treasury were politically motivated to influence corporate reporting policy in the absence of concerted political lobbying, and why this episode of government intervention led to an unanticipated regulatory outcome.
Polarisation in political Twitter conversations
Authors: Gunnarsson Lorentzen David 
Published: June 2014

Purpose– The purpose of this paper is to describe and analyse relationships and communication between Twitter actors in Swedish political conversations. More specifically, the paper aims to identify the most prominent actors, among these actors identify the sub-groups of actors with similar political affiliations, and describe and analyse the relationships and communication between these sub-groups.Design/methodology/approach– Data were collected during four weeks in September 2012, using Twitter API. The material included 77,436 tweets from 10,294 Twitter actors containing the hashtag #svpol. In total, 916 prominent actors were identified and categorised according to the main political blocks, using information from their profiles. Social network analysis was utilised to map the relationships and the communication between these actors.Findings– There was a marked dominance of the three main political blocks among the 916 most prominent actors: left block, centre-right block, and right-wing block. The results from the social network analysis suggest that while polarisation exists in both followership and re-tweet networks, actors follow and re-tweet actors from other groups. The mention network did not show any signs of polarisation. The blocks differed from each other with the right-wingers being tighter and far more active, but also more distant from the others in the followership network.Originality/value– While a few papers have studied political polarisation on Twitter, this is the first to study the phenomenon using followership data, mention data, and re-tweet data.
Global social media, local context
Authors: Cheng Yu-Chung , Chen Pai-Lin 
Published: June 2014

Purpose
– Social media connect individuals in different geographical location and allow people of different political and cultural backgrounds to discuss and participate in events that occur in distant corners of the globe. But, this does not suggest that social media promote homogeneous globalization. Rather, the local and its interactions with the global or regional views remain a powerful force in the realm of social media. The purpose of this paper is to take on the local/global factors in the social media service Twitter and analyzed the keyword-captured Chinese language tweets relating to the 2012 presidential election in Taiwan.

Design/methodology/approach
– Language code usage was used to sort out the community origins of Chinese language tweets relating to the election, given that distinct types and codes of Chinese characters are used within each political border. Community-specific patterns of communication were identified by cross-correlating language styles, tweeting frequency and participating users. Social network analysis was used to further characterize the local factors in the global social media.

Findings
– The authors found that the language styles and character types can be used to identify the regions to which the users belong. The authors were able to identify community-specific patterns of communication and reconstruct a social network that exhibits local characteristics.

Originality/value
– The results demonstrate that language code can be used to identify the community origin of Chinese tweets. This will enable fine-grain content-based analysis of the Chinese language social media.
Understanding the role of networking in organizations
Authors: Gibson Carter , H. Hardy III Jay , Ronald Buckley M. 
Published: June 2014

Purpose– The purpose of this paper is to review and synthesize research and theory on the definition, antecedents, outcomes, and mechanisms of networking in organizations.Design/methodology/approach– Descriptions of networking are reviewed and an integrated definition of networking in organizations is presented. Approaches for measuring and studying networking are considered and the similarities and differences of networking with related constructs are discussed. A theoretical model of the antecedents and outcomes of networking is presented with the goal of integrating existing networking research. Mechanisms through which networking leads to individual and organizational outcomes are also considered.Findings– Networking is defined as goal-directed behavior which occurs both inside and outside of an organization, focussed on creating, cultivating, and utilizing interpersonal relationships. The current model proposes that networking is influenced by a variety of individual, job, and organizational level factors and leads to increased visibility and power, job performance, organizational access to strategic information, and career success. Access to information and social capital are proposed as mechanisms that facilitate the effects of networking on outcomes.Originality/value– Networking is held to be of great professional value for ambitious individuals and organizations. However, much of the research on networking has been spread across various disciplines. Consequentially, consensus on many important topics regarding networking remains notably elusive. This paper reviews and integrates existing research on networking in organizations and proposes directions for future study. A comprehensive definition and model of networking is presented and suggestions to researchers are provided.
Keeping the peace
Authors: L. Kisamore Jennifer , W. Liguori Eric , Muldoon Jeffrey , Jawahar I.M. 
Published: June 2014

Purpose– The purpose of this paper is to investigate the interaction between self-reported proactive personality, competence, and interpersonal conflict in the prediction of supervisor ratings of organizational citizenship behaviors directed at individuals (OCBI) and organizations (OCBO).Design/methodology/approach– Data were obtained from 165 full-time subordinate-supervisor dyads. Employees self-reported personality and control variable information in wave 1 and competence and interpersonal conflict information in wave 2. Data regarding employee OCB performance were collected from supervisors in wave 3.Findings– Results suggest that OCBs are performed less frequently in stressful circumstances but that proactive personality appears to assuage the effects of stress. Significant two- and three-way interactions suggest the interplay of personal and situational characteristics are more complex in predicting OCBO than OCBI, likely due to its more distal nature.Practical implications– Results of the current study suggest steps managers may want to take to increase employee performance of OCBs, specifically, selecting proactive individuals, creating training programs to bolster employees’ competence, and minimizing interpersonal conflict at work.Originality/value– The current study confirms and extends extant research. The current study goes beyond previous work to consider a more complex interaction of factors that are related to employee engagement in OCBs.
Product recalls and product-harm crises
Authors: Tariq Anwar Syed 
Published: June 2014

Purpose– The aim of this study is to investigate and analyze product recalls and product-harm crises in the US toy industry, which is a major area in marketing and firms' competitiveness.Design/methodology/approach– By using longitudinal data from the US Consumer Product Safety Commission (CPSC), the paper uses content analysis to compare and contrast toy recalls, product hazards and country of origin issues of 721 toy recalls in the US market between 1974 and 2008, covering 270 million recalled toys.Findings– Findings of this work reveal that most of the recalled toys were manufactured in China, although a wide variety of toy brands were designed in the USA. Major hazards of toy recalls included choking, lead poisoning, aspiration, fire/burn and other injuries.Research limitations/implications– The study relied on the CPSC's data that seemed representative of the toy industry in the US market, but missed other markets of Europe and Asia. Also, there was availability of detailed data in sub-categories of the toy industry.Practical implications– The paper provides useful academic and managerial implications that can help us understand the issues of product recalls and product-harm crises.Social implications– Toys are one of the most widely available products in the world; the industry is a $50 billion industry and has transformed itself from a small-scale business sector into a well-established industry.Originality/value– This investigation is particularly important in the areas of firm-specific competitiveness, business ethics and regulatory and societal issues.
The role of the upper echelon in the value chain management
Authors: Agnihotri Arpita 
Published: June 2014

Purpose– The purpose of this study was to analyze the impact of top management teams on firms' value chain action intensity and value chain activity heterogeneity.Design/methodology/approach– The study was conducted from an emerging market perspective. The sample was based on the secondary data collected from three fast-growing industries in India: automobile, pharmaceutical and fast-moving consumer goods over the three-year period from 2009 to 2012. The Panel Poisson and Tobit regression have been used to conduct this study.Findings– Drawing upon the upper echelon theory, the author found that a top management team's educational level, functional heterogeneity and total organizational tenure influence value chain action intensity and value chain activity heterogeneity.Originality/value– The author introduces the concept of value chain action intensity and value chain action heterogeneity and investigates the role of the upper echelon in influencing intensity and heterogeneity.
Competitiveness of Spanish foreign subsidiaries
Authors: Miravitlles Paloma , Guitart-Tarrés Laura , Nuñez-Carballosa Ana 
Published: June 2014

Purpose
– The purpose of this study was to approach issues such as what type of value chain activities are carried on by the subsidiaries of multinationals located in Spain, where and how their resources and capabilities are generated and how these are transferred within the multinational. Creating resources and capabilities within a subsidiary of a multinational company enables it to gain competitiveness and therefore greater power of decision within the corporation.

Design/methodology/approach
– This research conducts a descriptive analysis of the value chain in Spanish subsidiaries. A population of 1,072 firms has been identified. To gather primary data, a questionnaire was designed based on international value chain and resources and capabilities literature.

Findings
– Analysis of the data gathered from 125 subsidiaries has enabled researchers to map out the profile of the value chain in these companies. The results indicate that the principal source of resources and capabilities is the subsidiary itself. Moreover, the experience built up over time is basic to the creation of skills in all the activities in the value chain.

Practical implications
– This is a matter of the subsidiaries identifying new opportunities to attain a new position or broaden their existing one.

Social implications
– Subsidiaries should benefit from favourable local policies to help them develop and strengthen their capabilities to obtain major international competitiveness.

Originality/value
– Although numerous studies assess the country's foreign direct investment flows, works concentrating on the presence of foreign capital in Spain are scarce. The growing interest in the international literature on the subsidiary as a unit of analysis makes this study interesting.
How to recover trust in the banking industry? A game theory approach to empirical analyses of bank and corporate customer relationships
Authors: Dahlstrom Robert , Nygaard Arne , Kimasheva Maria , M. Ulvnes Arne 
Published: June 2014

Purpose– Trust is a crucial element of a viable banking industry. In the corporate market though, the characteristics of the relationships between each corporate customer and the bank is a double-sided problem. Both parties might trust the other or choose to behave opportunistically. The paper aims to discuss these issues.Design/methodology/approach– The authors have analyzed the effects of inter-organizational trust and opportunism on the perception of risk. The paper presents a structural equations model based on a prisoner's dilemma logic to analyze the unique effects of trust between corporate customers and their banks and its corporate customers.Findings– The results based on 252 bank – corporate bank customers relationships reveal an intriguing mixed strategy between trust from one party and opportunism from the other.Research limitations/implications– The implication is that mutual trust seems to reduce the perception of risk in the market while bank opportunism significantly escalates perceived risk. The analyses also show that when the corporate customer trusts the bank, perceived risk is significantly reduced.Practical implications– The findings emphasize the role of relationship marketing in the banking industry.Originality/value– Despite the fact that inter-organizational trust is a crucial dyadic variable, few empirical studies have previously analyzed both sides of the relationship. This investigation is a preliminary analysis of how both sides of the same relationship affects the outcome. When trust erodes from one side of the relationship, it may lead to the same process on the other side of the relationship.
Making quality improvement programs more effective
Authors: Shaw-Taylor Yoku 
Published: June 2014

Purpose
– In the past 25 years, and as recent as 2011, all external evaluations of the Quality Improvement Organization (QIO) Program have found its impact to be small or difficult to discern. The QIO program costs about $200 million on average to administer each year to improve quality of healthcare for people of 65 years or older. The program was created to address questionable quality of care. QIOs review how care is provided based on performance measures. The paper aims to discuss these issues.

Design/methodology/approach
– In 2012, the author supported the production of quarterly reports and reviewed internal monitoring and evaluation protocols of the program. The task also required reviewing all previous program evaluations. The task involved many conversations about the complexities of the program, why impact is difficult to discern and possible ways for eventual improvement. Process flow charts were created to simulate the data life cycle and discrete event models were created based on the sequence of data collection and reporting to identify gaps in data flow.

Findings
– The internal evaluation uncovered data gaps within the program. The need for a system of specification rules for data conceptualization, collection, distribution, discovery, analysis and repurposing is clear. There were data inconsistencies and difficulty of integrating data from one instance of measurement to the next. The lack of good and reliable data makes it difficult to discern true impact.

Practical implications
– The prescription is for a formal data policy or data governance structure to integrate and document all aspects of the data life cycle. The specification rules for governance are exemplified by the Data Documentation Initiative and the requirements published by the Data Governance Institute. The elements are all in place for a solid foundation of the data governance structure. These recommendations will increase the value of program data.

Originality/value
– The model specifies which agency units must be included in the governance authority and the data team. The model prescribes in detail a data governance model to address gaps in the life cycle. These prescriptive measures will allow the program to integrate all of its data. Without this formal data governance structure, the QIO program will be undetermined by the persistent lack of good data for monitoring and evaluation.
Moving to patient reported collection of race and ethnicity data
Authors: Berry Carolyn , A. Kaplan Sue , Mijanovich Tod , Mayer Andrea 
Published: June 2014

Purpose– The purpose of this paper is to examine the feasibility of collecting standardized, patient reported race and ethnicity (RE) data in hospitals, and to assess the impact on data quality and utility.Design/methodology/approach– Part of a larger evaluation that included a comprehensive assessment. Sites documented RE data collection procedures before and after program implementation. Primary data collected through qualitative interviewing with key respondents in ten hospitals to assess implementation. Nine hospitals provided RE data on the same patients before and after implementation new data collection procedures were implemented to assess impact.Findings– Implementation went smoothly in nine of ten hospitals and had substantial effects on the hospital staff awareness on the potential for disparities within their hospitals. New procedures had minimal impact on characterization of readmitted patients.Practical implications– This study demonstrated that it is feasible for staff in a diverse group of hospitals to implement systematic, internally standardized methods to collect self-reported RE data from patients.Originality/value– Although this study found little impact patients’ demographic characterizations, other benefits included greater awareness of and attention to disparities, uncovering small pockets of minorities, and dramatically increased RE data use in quality improvement efforts.
