ABSTRACTBackground:Hyperbilirubinemia is a common neonatal problem. The present study aimed to investigate the effect of ursodeoxycholic acid in reducing indirect hyperbilirubinemia of infants under phototherapy.Methods:This double‐blind randomized clinical trial was conducted on neonates with jaundice, who had received phototherapy in the hospitals affiliated with the Shiraz University of Medical Sciences in 2013. A total of 80 neonates were enrolled in the study and were randomly divided into 2 groups. The intervention group (n = 40) with indirect hyperbilirubinemia received 10 mg · kg−1 · day−1 divided every 12 hours Ursobil (capsule 300 mg) in addition to phototherapy, whereas the control group (n = 40) received only phototherapy. Total bilirubin levels were measured every 12 hours until reaching <10 mg/dL, and then phototherapy was disrupted. The duration of phototherapy was measured. The 2 groups were compared regarding total bilirubin levels at different time points and duration of phototherapy using the generalized estimating equation (GEE) test.Results:The mean of total bilirubin in the intervention group was 12 ± 1.6, 10 ± 1.1, and 9.8 ± 0.2 mg/dL 12, 24, and 48 hours after the beginning of phototherapy, respectively. On the contrary, these measures were 14.4 ± 1.3, 12.5 ± 1.4, and 10.1 ± 1.1 mg/dL in the control group, respectively, (P < 0.05). The mean time required for phototherapy to decrease the bilirubin level to <10 mg/dL was 15.5 ± 6 and 44.6 ± 13.3 hours in the case and the control group, respectively, (P = 0.001).Conclusions:Ursodeoxycholic acid had additive effect with phototherapy in neonates with indirect hyperbilirubinemia. This drug also reduced the time period needed for phototherapy and, consequently, decreased the hospitalization period.
Stable eusociality via maternal manipulation when resistance is costless
Authors: González-Forero Mauricio 
Published: May 2015

AbstractIn many eusocial species, queens use pheromones to influence offspring to express worker phenotypes. While evidence suggests that queen pheromones are honest signals of the queen’s reproductive health, here I show that queen’s honest signaling can result from ancestral maternal manipulation. I develop a mathematical model to study the coevolution of maternal manipulation, offspring resistance to manipulation, and maternal resource allocation. I assume that (1) maternal manipulation causes offspring to be workers against offspring’s interests; (2) offspring can resist at no direct cost, as is thought to be the case with pheromonal manipulation; and (3) the mother chooses how much resource to allocate to fertility and maternal care. In the coevolution of these traits, I find that maternal care decreases, thereby increasing the benefit that offspring obtain from help, which in the long run eliminates selection for resistance. Consequently, ancestral maternal manipulation yields stable eusociality despite costless resistance. Additionally, ancestral manipulation in the long run becomes honest signaling that induces offspring to help. These results indicate that both eusociality and its commonly associated queen honest signaling can be likely to originate from ancestral manipulation.

Abstract
Dormancy is a complex evolutionary trait that temporally prevents seed germination, thus allowing seedling growth at a favorable season. High-throughput analyses of transcriptomes have led to significant progress in understanding the molecular regulation of this process, but the role of posttranscriptional mechanisms has received little attention. In this work, we have studied the dynamics of messenger RNA association with polysomes and compared the transcriptome with the translatome in dormant and nondormant seeds of Arabidopsis (Arabidopsis thaliana) during their imbibition at 25°C in darkness, a temperature preventing germination of dormant seeds only. DNA microarray analysis revealed that 4,670 and 7,028 transcripts were differentially abundant in dormant and nondormant seeds in the transcriptome and the translatome, respectively. We show that there is no correlation between transcriptome and translatome and that germination regulation is also largely translational, implying a selective and dynamic recruitment of messenger RNAs to polysomes in both dormant and nondormant seeds. The study of 5′ untranslated region features revealed that GC content and the number of upstream open reading frames could play a role in selective translation occurring during germination. Gene Ontology clustering showed that the functions of polysome-associated transcripts differed between dormant and nondormant seeds and revealed actors in seed dormancy and germination. In conclusion, our results demonstrate the essential role of selective polysome loading in this biological process.
Relationship between the maturity of supply chain process management and the organisational life cycle
Authors: Souza Rodrigo Paiva , Guerreiro Reinaldo , Oliveira Marcos Paulo Valadares 
Published: May 2015

Purpose
– The purpose of this paper is to investigate the relationship between the maturity level of supply chain process management (SCPM) and the company’s organisational life cycle (OLC).

Design/methodology/approach
– Based on a theoretical review, a questionnaire was developed to measure the maturity level of SCPM and the OLC. Data from 228 companies operating in Brazil were collected to assess the association between variables by using correspondence analysis technique.

Findings
– Among the key findings, evidences of a relationship between the maturity level of SCPM and the company’s OLC could be highlighted. In addition, it was found that the maturity level of SCPM has no significant relationship with the age or size of a company but it is related to the capabilities inherent to the SCPM.

Research limitations/implications
– Measurement of SCPM and the OLC was based on the managers’ perceptions about the actual configuration of their firms. Accordingly, there is a certain level of subjectivity inherent to those models. The study is valid for companies operating in Brazil and might not be applicable for other countries.

Practical implications
– This study increases awareness about the influence of organisational issues, such as the decision model, power hierarchy or governance structure, in the development of SCPM maturity. Such issues must be addressed to develop SCPM.

Social implications
– Management and control of organisational issues might help to develop the maturity of SCPM, so the service level of companies, in order to deliver high quality services to society. Still, further research is required in the social area.

Originality/value
– The paper tried to analyse the relationship of two well established models where this link was overlooked in the past. It was not found in literature similar investigation.
A conceptual framework of RFID adoption in retail using Rogers stage model
Authors: Bhattacharya Mithu 
Published: May 2015

Purpose– The purpose of this paper is to develop a research model that links Radio Frequency Identification (RFID) adoption issues with established technology adoption stages suggested by Rogers theory of diffusion of innovation (DOI). The research model proposed in this study suggests that RFID adoption in retail industry progresses in different stages.Design/methodology/approach– A mixed methodological perspective is used in this research. Key research issues were identified from a systematic content analysis of trade and academic articles in the first phase.Findings– Data collected from Delphi study is used to test the propositions. It confirms key research issues associated with different adoption stages. Finally, it also confirms that the stages (knowledge, persuasion, design and decision, and implementation) influence RFID adoption decision.Research limitations/implications– The propositions that are developed in the model can be used in future studies for further development. More relevant items should be added to measure each variable. It can also allow future researchers and practitioners to take a more comprehensive approach to look at RFID adoption process as a whole and thus focus on relevant issues across all adoption stages.Practical implications– The research model can provide insights to practitioner to make more informed RFID adoption decisions.Originality/value– Rogers stage model is very important for technology diffusion studies but is not explored much. There is limited research on understanding the overall RFID adoption process. This study is an attempt to bridge that gap and draw attention toward future research in that direction. The research model that is developed links RFID research with existing research in the area of DOI.
What is the biggest question in CSR research?
Authors: Ahen Frederick , Zettinig Peter 
Published: May 2015

Purpose– Corporate social responsibility (CSR) is an issue-oriented substantive domain. Nevertheless, there are countless socio-economic, medico-techno-scientific, environmental and ethical philosophical questions that are far from being settled. In pursuit of a more desirable and sustainable future, this work problematizes current corporate responsibility (CR) research, education and practice.Design/methodology/approach– This contribution provides a critical perspective on the future of CR research and practice and offers a way forward based on theoretical prescience.Findings– The paper delineates a taxonomy of typical crises, categorized asburning, existential, overlookedandneglected crises. This taxonomy can be used as a tool for all forms of scenario analysis, empirical work and policymaking. This allows various futures issues to be given targeted interventions, assigned a focal theory, or allocated differentiated resources and appropriate time and space depending on their technical nature and the institutional context within which the issues unfold.Social implications– This paper argues that CR research risks losing steam despite its near ubiquitous nature and the major contributions hitherto made. Nevertheless, when problems are strategically thought out in the light of the taxonomy above, they provide promising avenues for insightful research and value-creating practice to meet the expectations of both business and society.Originality/value– A profound chasm exists between CR practice and rhetoric. This void is particularly stark when we consider the interface between science and technology and developing economies. This paper explores desirable futures for CR while analyzing what is possible and probable.
Cave wall to internet, storytelling, the ancient learning art
Authors: Beamish Gerry , Beamish Jonathan 
Published: May 2015

Purpose
– The purpose of this paper is to show the value of storytelling in developing organisational culture and values, facilitating change and accelerating learning.

Design/methodology/approach
– The paper looks at why storytelling is important and how it has survived and adapted to changing technologies.

Findings
– Storytelling is crucial in bridging the knowledge/action gap that is at the centre of most management, change and learning problems. The fact that oral storytelling has survived so many changes in technology is testament to its value but more recent research has underlined the scientific reasons for its success.

Originality/value
– A story is the only way to activate parts in the brain so that a listener turns the story into their own ideas and experience. In terms of influencing there is nothing more powerful than people thinking that the idea is their own. When people believe the idea is their own they put all their energies behind implementing it thus reinforcing culture/values and facilitating learning and change.
Corporate psychopathy: deviant workplace behaviour and toxic leaders – part one
Authors: Cheang Henry S. , Appelbaum Steven H. 
Published: May 2015

Purpose– Increasingly, it is recognized that (larger) organizations have many employees who present with corporate psychopathy (i.e. a milder version of antisocial personality disorder (APD)). Importantly, such a disorder contributes to the presence of deviant workplace behaviour. Organizations must therefore adapt its practices to both identify and manage employees who either present with, or have tendencies towards, corporate psychopathy. As a means of developing a guiding framework for organizational adaptation, the purpose of this two-part paper is to offer two reviews of relevant research. The first revolves around the body of knowledge regarding corporate psychopathy and the primary, established behavioural method of identifying its presence; the second is a brief review on physiological measures that can complement current gold standards.Design/methodology/approach– A range of published empirical and practitioner research articles were reviewed to elaborate on APD and corporate psychopathy; showcase the efficacy of the currently most accepted method of detecting psychopathic behaviour – the Psychopathy Checklist (PCL) and; highlight physiological methods of detecting psychopathic tendencies which may complement usage of the PCL – electroencephalography, measurement of galvanic skin responses, and electromyography.Findings– Deviant workplace behaviours cause losses of billions of dollars across all business organizations, and much of this behaviour stems from corporate psychopaths in positions of leadership; the PCL, while useful, can nonetheless yield sharp differences in the identification of psychopathy across different administrators of the test; measures of physiological states show good reliability in discriminating psychopathic persons from non-psychopathic persons. Based on these findings, the authors propose guidelines for how to identify and mitigate the effects of corporate psychopathy for organizations.Research limitations/implications– The proposed guidelines must be tested in an empirical paper to measure their effectiveness.Practical implications– The paper suggests an overall framework that may help leaders and organizational development practitioners identify the major factors which may be considered to safeguard against the potentially detrimental conduct of corporate psychopaths in their organizations.Social implications– This paper highlights the need to identify and ward against the presence of corporate psychopaths. There needs to be guidelines for organizations on how to identify and mitigate the effects of corporate psychopathy for organizations.Originality/value– The suggestion of integrating physiological methods of detection with the PCL, as well as urging proactive education of all employees as the symptoms and effects of corporate psychopathy, is the novel contribution of the paper.
Economic sustainability of ground mounted photovoltaic systems: an Italian case study
Authors: Campisi Domenico , Morea Donato , Farinelli Elisa 
Published: May 2015

Purpose
– The purpose of this paper is to evaluate the expected cost of a large-sized photovoltaic (PV) system (= 1 MW) in reaching grid parity, not taking into account any type of government incentives (now quite uncommon in industrialized countries). A PV system located in Southern Italy will be the subject of this assessment.

Design/methodology/approach
– The paper presents the case of a 1 MW ground-mounted PV system. The data regarding solar radiation on the surface of the modules and the relative solar diagrams were simulated and reported using PVSYST® 5.21 software. To evaluate the profitability and solvency of the project, a number of factors were taken into consideration: profitability indicators of net present value and internal rate of return, the debt service coverage indicators of debt service cover ratio and loan life cover ratio and their mean annual values (annual debt service cover ratio and annual loan life cover ratio, respectively). A sensitivity analysis with respect to the most critical element (weighted average cost of capital) gave strength to the results.

Findings
– The achievement of grid parity for 200 kW PV systems is happening globally in areas with higher irradiation, but it clearly refers to residential utilities and is not applicable to large systems. The case study considers a power plant (= 1 MW) to assess the total cost that it would need to have to be economically advantageous.

Research limitations/implications
– This is an assessment made using a case which, given an average irradiance value in the area and the energy produced, can be used in all countries lying in the temperate zone. For other areas, a scaling coefficient would be needed.

Practical implications
– The paper is useful for understanding the order of cost, which must catch up to PV technology to make investments in power plants profitable in the absence of government incentives. It is also helpful for those who make government policies so that these may propose possible incentives commensurate with the actual difference between the value of the technology and the value of the investment. The study is also useful for a possible comparison with a system sharing the same characteristics (size, energy production) for off-grid use and customers.

Originality/value
– The study can be a valuable support for government policies to incentivate PV systems that contribute to a reduction of greenhouse gases and that help contain climate change. The case study represents a real case taken directly from a real project. This case study and its sustainable features have not been previously presented in a scientific journal.
From environmentalism to corporate environmental accountability in the Nigerian petroleum industry
Authors: Hassan Aminu , Kouhy Reza 
Published: May 2015

Purpose– The purpose of this paper is to explore firm–stakeholder environmental accountability relationship in the Nigerian oil and gas industry.Design/methodology/approach– The paper develops, from the interdisciplinary literature, a normative framework that links the dominant environmentalism paradigm to the business-firm-causality environmental philosophy. The link is underpinned by the theory of stakeholder identification and salience to enable the identification and evaluation of the importance placed on each environmental stakeholder group by oil and gas companies in the Nigerian oil and gas sector.Findings– This paper submits that three factors, originating from how these companies identify and classify green stakeholders, lead to little and unimpressive efforts to effectively discharge environmental accountability. These factors include weak, legal powers of regulatory environmental stakeholders; non-recognition of the host communities as powerful environmental stakeholders; and non-recognition of the Nigerian public as legitimate environmental stakeholders.Social implications– Underestimating the importance of some key, environmental stakeholders and the weak powers of regulatory environmental stakeholders leads to limited commitments to environmental accountability by oil and gas companies operating in Nigeria. Inevitably, this results in persistent conflict, violence, destruction of the oil companies’ properties and other various forms of unrest common in the Niger Delta.Originality/value– The paper develops a unique normative framework from the relevant literature in environmental ethics, environmental management and environmental accounting that are used to evaluate firms-stakeholder environmental accountability relationship.
Investigation on the effectiveness of ABC algorithm for hydrothermal energy management considering emission aspects
Authors: Moorthy V , Sangameswararaju P , Ganesan S , Subramanian S 
Published: May 2015

Purpose– The purpose of the paper is to solve hydrothermal scheduling (HTS) problem for energy-efficient management by allocating the optimal real power outputs for thermal and hydroelectric generators.Design/methodology/approach– HTS can be formulated as a complex and non-linear optimization problem which minimizes the total fuel cost and emissions of thermal generators subject to various physical and operational constraints. As the artificial bee colony algorithm has proven its ability to solve various engineering optimization problems, it has been used as a main optimization tool to solve the fixed-head HTS problem.Findings– A meta-heuristic search technique-based algorithm has been implemented for hydrothermal energy management, and the simulation results show that this approach can provide trade-off between conflict objectives and keep a rapid convergence speed.Originality/value– The proposed methodology is implemented on the standard test system, and the numerical results comparison indicates a considerable saving in total fuel cost and reduction in emission.
Integrate inconsistent and heterogeneous data based on user feedback
Authors: Lu Lihua , Zhang Hengzhen , Gao Xiao-Zhi 
Published: May 2015

Purpose
– Data integration is to combine data residing at different sources and to provide the users with a unified interface of these data. An important issue on data integration is the existence of conflicts among the different data sources. Data sources may conflict with each other at data level, which is defined as data inconsistency. The purpose of this paper is to aim at this problem and propose a solution for data inconsistency in data integration.

Design/methodology/approach
– A relational data model extended with data source quality criteria is first defined. Then based on the proposed data model, a data inconsistency solution strategy is provided. To accomplish the strategy, fuzzy multi-attribute decision-making (MADM) approach based on data source quality criteria is applied to obtain the results. Finally, users feedbacks strategies are proposed to optimize the result of fuzzy MADM approach as the final data inconsistent solution.

Findings
– To evaluate the proposed method, the data obtained from the sensors are extracted. Some experiments are designed and performed to explain the effectiveness of the proposed strategy. The results substantiate that the solution has a better performance than the other methods on correctness, time cost and stability indicators.

Practical implications
– Since the inconsistent data collected from the sensors are pervasive, the proposed method can solve this problem and correct the wrong choice to some extent.

Originality/value
– In this paper, for the first time the authors study the effect of users feedbacks on integration results aiming at the inconsistent data.
