Business user impact on information system projects
Authors: Eichhorn Bradford , Tukel Oya 
Published: April 2018

PurposeThere are differing views and results in the literature regarding whether the user’s participation has a positive or negative impact, if any, on the success of an information system (IS) project. The purpose of this paper is to develop a comprehensive model with four main hypotheses to test the relationships between seven constructs using survey data conducted in the USA.Design/methodology/approachThe authors develop a structural equation model (SEM) with four constructs defining the activities the user participates in and three constructs defining user satisfaction as a measure of project success. As such, the proposed SEM is the most comprehensive among the models offered in the literature to date, and includes, for the first time, a presentation requirement construct as a specific system requirement for possible user participation.FindingsThe authors find that a business user’s participation in functional requirements benefits project outcome, whereas business users should not participate in gathering presentation requirements unless they are experienced middle managers.Research limitations/implicationsThis study surveyed many industries across the USA and provided a solid statistical base for analysis. Future research should consider exploring IS projects in other countries since various cultures can differ in how they approach to such projects. Additionally, industries are known to have dissimilar needs; therefore, a study exploring specific industries would add to the available research.Practical implicationsThe authors find that when the general business user participates in certain activities that relate to presentation of the system, his/her involvement negatively impacts the project success. However, if that business user is a middle manager, he/she has a positive impact on the project success. Similarly, when the business user participates in managing the projects, that involvement negatively impacts the project outcome (although the amount of negative impact is relatively small). These results should have an influence on the way the IS project managers allocate business resources to activities, and their decisions regarding whether and where the business users participate.Social implicationsThe authors expect higher levels of business user satisfaction on IS projects if they are allocated to a limited subset of project activities that has a positive impact on project outcomes.Originality/valueThe authors believe these findings contribute to this research domain considerably since they are based on a large sample size on a new comprehensive model of business users that can be generalized across industries. The separation of business requirements into functional and presentation requirements has suggested that there are differing impacts to the project depending on the type of business user involved.
An integrated model for allocation and leveling of human resources in IT projects
Authors: Celkevicius Roberto , Russo Rosaria F.S.M. 
Published: April 2018

PurposeThe purpose of this paper is to propose an integrated model for allocation and leveling of human resources in IT projects.Design/methodology/approachA single case study was conducted in a large company of IT outsourcing services, which were assessed the management of 14 projects. The survey was conducted through interviews with project managers, and digital files and internal documents of the organization related to these projects.FindingsIn the analysis, it was identified that the critical path is not identified in all projects, and even when this happens, resources are not allocated in the first tasks in that path. A committee controls the allocation of resources with the assessment of skills, but there is no control of all resource constraints.Research limitations/implicationsThe main limiting factors for this study are: use of data of one company in the IT industry, making it difficult to generalize the model for other sectors companies; it was noted during interviews that the project managers interviewed do not always know in detail all the company’s processes for allocation and resource leveling, due to the large number of processes and different management activities of these professionals.Practical implicationsA model and actions for this implementation was proposed, such as training for the use of the technique of critical path; allocation and leveling done simultaneously; decisions of the management committee based on information of availability, key skills, holidays, days off of human resources; development of a software tool that integrates this information, generating graphical interfaces that are not provided by project management software with the use of an allocation factor.Social implicationsThe characteristics of the proposed model, as well as the use of the allocation factor, can help managers to validate their allocation models and leveling of human resources in an integrated manner.Originality/valueThe study explains that the granularity of analysis of resource allocation increases by decomposition of the duration of each activity in fixed time segments. It is suggested to use the mathematical concept of the allocation factor (Fa).
Microfinance and microenterprise performance in Indonesia: an extended and updated survey
Authors: Atmadja Adwin Surja , Sharma Parmendra , Su Jen-Je 
Published: April 2018

PurposeThe purpose of this paper is to address the small, women micro-entrepreneur dominated and heterogeneity limitations of the Atmadjaet al.(2016) study. The sample is much larger, includes more men and is more heterogeneous, which allows deeper insights and more meaningful explanation of the relationship between microfinance and microenterprise performance in the case of Indonesia, including the effects of gender, lending scheme and money separation.Design/methodology/approachThis study used a survey of 556 respondents across five microcredit providers in the city of Surabaya using an updated instrument. Ordered probit is used to analyse data.FindingsMicrofinance may not matter for microenterprise performance in the case of Indonesia. Additionally, microcredit schemes (individual vs group) and gender may also not matter for performance, but money separation might have some influence.Practical implicationsNon-financial factors such as human capital, spousal involvement, and money separation should be considered as important factors for improving microenterprise business performance in Indonesia, with less focus on microcreditper se.Originality/valueThis study provides further evidence that microfinance may not matter for microenterprise performance in the case of Indonesia, a populous middle income country with a very long history of microfinance.
The impact of remittances on Sudan’s economic growth: does the exchange rate matter?
Authors: Awad Atif , Sirag Abdalla 
Published: April 2018

PurposeThe purpose of this paper is to investigate the presence of the Dutch disease hypothesis through examining the remittance-growth nexus using annual data for Sudan covering the period 1977-2015. The paper seeks to answer the following critical questions: what is the impact of remittance on Sudanese economy? How exchange rate influences the impact of remittance on growth? To what extent the impact of remittance on growth differs between the short and long run.Design/methodology/approachThe paper employs the autoregressive distributive lag (ARDL) technique because of its several advantages.FindingsThe ARDL results show evidence against the existence of such a hypothesis. More specifically, the results show that over time, due to the structured nature of the economy, remittances may affect economic growth negatively through several mechanisms including the depreciation rather than the appreciation of the exchange rate.Originality/valueAfter 2011 and the secession of South Sudan, Sudan lost more than 80 per cent of foreign exchange revenues which reflected in the sharp gap between the official rate and the parallel exchange rate equal to 150 per cent. To lessening this gap, the attention was given to expatriates to encourage them to transfer their remittances through official channels. Since remittance and exchange rate mechanism may affect growth positively or negatively, no study addressed this possibility. This is the first empirical study in this matter that considers both the temporary and the permanent impacts.
Chinese consumers’ willingness to pay for rice
Authors: Xu Pei , Su Hang , Lone Todd 
Published: April 2018

Purpose
China’s expanded rice imports offer a profitable business opportunity for both domestic and international grain marketers. The purpose of this paper is to analyze the impact of select variables on Chinese consumers’ rice choices, specifically focusing on country-of-origin, price, organic, brand, freshness, and taste. The study concludes with suggestions for domestic and international rice marketers to help them develop more efficient rice marketing plans.

Design/methodology/approach
This study developed a conditional logit model to analyze survey data gathered from Chongqing and Chengdu, two of China’s largest rice consumption cities.

Findings
Chinese consumers are price sensitive in their rice choices. Country-of-origin is the most imperative factor affecting rice selection for lower food expense consumers but branded rice attracts the attention of higher food expense consumers. Furthermore, these higher food expense consumers are willing to pay a small premium of $0.22 for a pound of organic rice.

Research limitations/implications
A general trend in demand for organic rice from higher food expense consumers was identified, and this trend predicts a profitable market for organic rice sellers. However, these research findings are geographically limited and may only represent a consumption trend from the two sampled cities rather than all of China.

Originality/value
The study concludes with meaningful recommendations to rice marketers to aid in developing profitable market entrance strategies to China.
Compensation for harm caused by nuclear installations: what’s the damage?
Authors: Lee Robert , Stech Radek 
Published: April 2018

Purpose
This paper aims to explain the changes to the liability regime for nuclear installations before reviewing the traditional heads of damage under the 1965 Act. It argues that while there is some welcome clarification of what amounts to an “occurrence” in the purposes of the 1965 Act, disappointingly, little has been done to clarify how concepts of personal injury and property damage under the Act sit alongside traditional tort notions leaving the law highly dependent on earlier, but not always consistent, case law. The paper then goes on to consider the impact of the new categories of compensation, introduced by the Order, evaluating the extent to which these draw upon EU law structures for environmental impairment liability. Again, it questions whether this approach will achieve sufficient clarity and certainty.

Design/methodology/approach
This paper is a desk-based legal research.

Findings
This study is a discussion of statutory material and case law.

Originality/value
This paper is a first in-depth treatment of changes to liability principles in the Nuclear Installations Act 1965.
Sanokondu
Authors: Busari Jamiu , Chan Ming-Ka , Dath Deepak , Matlow Anne , Meschino Diane de Camps 
Published: April 2018

Purpose
This paper aims to describe the evolution of Sanokondu, highlighting the rationale, achievements and lessons learnt from this initiative. Sanokondu is a multinational community of practice dedicated to fostering health-care leadership education worldwide. This platform for health-care leadership education was conceived in 2014 at the first Toronto International Summit on Leadership Education for Physicians (TISLEP) and evolved into a formal network of collaborators in 2016.

Design/methodology/approach
This paper is a case study of a multinational collaboration of health-care leaders, educators, learners and other stakeholders. It describes Sanokondu’s development and contribution to global health-care leadership education. One of the major strategies has been establishing partnerships with other educational organizations involved in clinical leadership and health systems improvement.

Findings
A major flagship of Sanokondu has been its annual TISLEP meetings, which brings various health-care leaders, educators, learners and patients together. The meetings provide opportunities for dialog and knowledge exchange on leadership education. The work of Sanokondu has resulted in an open access knowledge bank for health-care leadership education, which in addition to the individual expertise of its members, is readily available for consultation. Sanokondu continues to contribute to scholarship in health-care leadership through ongoing research, education and dissemination in the scholarly literature.

Originality/value
Sanokondu embodies the achievements of a multinational collaboration of health-care stakeholders invested in leadership education. The interactions culminating from this platform have resulted in new insights, innovative ideas and best practices on health-care leadership education.
Turning the Titanic: physicians as both leaders and managers in healthcare reform
Authors: Grady Colleen Marie , Hinings C.R. (Bob) 
Published: April 2018

Purpose
Physicians are instrumental in healthcare reform and their capacity to employ both leadership and management skills can affect change at all levels. This paper aims to present the challenges and opportunities for physicians in influencing system change and discuss how the two different but complementary skill sets may enable them to contribute to transformation of healthcare.

Design/methodology/approach
This is a conceptual paper and represents the viewpoints of both authors while incorporating current evidence through the literature.

Findings
Healthcare reform is important and underway in many Canadian provinces, yet it is difficult to achieve change. Leadership and management skills differ although these differences are often subtle in language. Physicians both lead and manage in the healthcare system; their capacity to do both is an advantage for healthcare reform.

Originality/value
This paper represents the opinions of both authors and is considered original as a conceptual paper.
Can leader “humility” spark employee “proactivity”? The mediating role of psychological empowerment
Authors: Chen Yanhong , Liu Baowei , Zhang Li , Qian Shanshan 
Published: April 2018

PurposeThe purpose of this paper is to investigate the effect of humble leadership on employee proactive behavior. The authors propose that such effect is mediated by psychological empowerment, and identification with leader moderates the intervening role of psychological empowerment in the humble leadership-employee proactive behavior relationship.Design/methodology/approachData were collected from 286 subordinate-supervisor dyads from 4 industries in Northern China. Hierarchical linear modeling analyses were applied to test the research model.FindingsHumble leadership has a significantly positive effect on employee proactive behavior, and this effect is mediated by psychological empowerment. Furthermore, the identification with leader moderates the mediated relationships between humble leadership and employee proactive behavior via psychological empowerment.Research limitations/implicationsOne limitation is that the data were collected cross-sectionally. Further research could conduct longitudinal research to retest the hypotheses. The present research has a number of implications. First, the authors extend humble leadership research. Second, the authors also contribute to humble leadership literature by addressing the lack of attention paid to the explanatory mechanism linking humble leader behavior to follower outcomes. Third, the authors provide a new insight into the boundary condition of humble leadership.Practical implicationsManagers should demonstrate more humble behaviors in their leading process to influence employees’ psychological empowerment and proactive behavior. In addition, managers should provide employees with sincere care in relation to work and life issues to produce employees’ identification with leader.Social implicationsHumility is a modifiable trait that individuals can increase dramatically by practice. Humble behavior is more accessible and easier to cultivate, contrary to the stable trait of humility. Besides, our results confirmed the individuals with the virtue of humility are most likely to succeed. Thus, humble behaviors should be highly advocated and encouraged in our society.Originality/valueThis research extends humble leadership research by constructing and verifying the theoretical model of humble leader behavior and employee proactive behavior and by demonstrating the value of humble leader behavior in a non-Western context, and identifies the different roles of psychological empowerment and identification with leader on employee proactive behavior.
A more accurate solution of nonlinear conservative oscillator by energy balance method
Authors: Molla Md Helal Uddin , Razzak Md Abdur , Alam M.S. 
Published: April 2018

Purpose
The purpose of this paper is to present an analytical approximate technique to solve nonlinear conservative oscillator based on the He’s energy balance method (improved version recently presented by Khan and Mirzabeigy). The method is illustrated by solving double well Duffing oscillator.

Design/methodology/approach
The Duffing equation with a double-well potential (with a negative linear stiffness) is an important model of a mass particle moving in a symmetric double well potential. This form of the equation also appears in the transverse vibrations of a beam when the transverse and longitudinal deflections are coupled (Thompsen, 2003).

Findings
The approximate solutions obtained by the present technique have good agreement with the numerical solution and also provide better results than other existing methods.

Originality/value
The results are more accurate than those obtained by other existing methods. The relative errors obtained by the present paper are less than those obtained by other existing methods. Therefore, the present technique is very effective and convenient for solving nonlinear conservative oscillator.
Maintenance of Remission in antineutrophil cytoplasm antibody‐associated vasculitides
Authors: Guillevin Loïc , Terrier Benjamin 
Published: April 2018

AbstractThe classification of the systemic vasculitides has been controversial for several decades. The Chapel Hill consensus Conference definitions originally developed in 1994, but revised and extended in 2012 are now widely accepted. The American College of Rheumatology (ACR) criteria were first published in 1990, are now generally accepted to be out of date and new criteria are needed. More recently the classical division of the ANCA vasculitides using clinical phenotype has come under scrutiny with evidence from epidemiological, genetic and outcome studies that perhaps these conditions should be classified on the basis of ANCA specificity into PR3‐ANCA positive and MPO‐ANCA positive groups. The traditional distinction between giant cell arteritis and Takayasu arteritis has been questioned and some recent studies of GCA have included patients with only extra‐cranial disease. The Diagnostic and Classification Criteria of Vasculitis study (DCVAS) will provide new validated classification criteria for the systemic vasculitides.
Bone marrow as a target organ of systemic lupus erythematosus: analysis of cases with myelofibrosis
Authors: Üsküdar Cansu Döndü , Üsküdar Teke Hava , Işiksoy Serap , Korkmaz Cengiz 
Published: April 2018

AbstractAimCytopenia in the course of systemic lupus erythematosus (SLE) may be due to multiple factors. In this study, we aimed primarily to evaluate the detailed results of bone marrow (BM) biopsies of SLE patients, secondly to determine the myelofibrosis (MF) frequency and thirdly to compare BM morphologic findings as well as the clinical and laboratory parameters between groups (with MF and without MF) in cytopenic SLE patients.MethodsWe retrospectively analyzed 224 SLE patients’ files. Patients were divided into two groups according to whether they had MF or not. Concurrent SLE organ involvements, medical therapy and detailed BM findings were recorded.ResultsForty‐five (20%) of 224 SLE patients were found to have undergone BM biopsy due to cytopenia. Four patients were excluded (two drug‐induced cytopenia, one lymphoma, one insufficient BM biopsy samples). While MF was detected in 29 (70.7%) of the 41 patients, 12 patients did not have MF. Between the two groups, no differences were identified in terms Systemic Lupus Erythematosus Disease Activity Index, BM cellularity, or BM dysplastic changes (P = 0.788, P = 0.672 and P = 0.494, respectively). In the SLE‐associated MF group, 27 patients responded to immunosuppressive therapy and corticosteroids, but two patients were unresponsive. The response time was longer for the SLE‐associated MF group compared to the without MF group (3.3 ± 3.1 months vs. 1.7 ± 1.2 months, P = 0.091). Correlation analysis revealed that increased degree of BM fibrosis delayed the response time (r = 0.471, P = 0.002).ConclusionsMF is common in SLE patients. SLE‐associated MF as an additional factor for cytopenia in SLE patients may lead to delayed response to appropriate therapy, which may be dependent on the increased grade of BM fibrosis.
Applying a Developmental Framework to the Self‐Regulatory Difficulties of Young Children with Prenatal Alcohol Exposure: A Review
Authors: Reid Natasha , Petrenko Christie L. M. 
Published: April 2018

Prenatal alcohol exposure (PAE) can be associated with significant difficulties in self‐regulatory abilities. As such, interventions have been developed that focus on improving varying aspects of self‐regulation for this population. The application of a multilevel theoretical framework that describes the development of self‐regulation during early childhood could further advance the field. First, this framework could assist in elucidating mechanisms in the trajectories of early adjustment problems in this population and, second, informing the development of more precise assessment and interventions for those affected by PAE. The aims of the current review were to provide an overview of the self‐regulatory framework proposed by Calkins and colleagues (e.g., Calkins, 2007; Calkins and Fox, 2002); examine the self‐regulatory difficulties that are commonly experienced during infancy (i.e., 0 to 2 years) and early childhood (i.e., 3 to 8 years) in children with PAE in the context of the developmental framework; and describe how the framework can inform the development of future assessment and intervention provision for young children with PAE. The application of a developmental framework, such as proposed by Calkins and colleagues, allows for a systematic and theoretically driven approach to assessment and intervention programs for young children with PAE.
Genome‐wide association study confirms that the chromosome Z harbours a region responsible for rumplessness in Hongshan chickens
Authors: Wang Q. , Pi J. , Shen J. , Pan A. , Qu L. 
Published: April 2018

SummaryRumplessness in Hongshan chickens has been reported as a novel sex‐linked characteristic. Re‐sequencing data suggest that a pseudogene on the Z chromosome, LOC431648, is affiliated with this phenotype. In this study, we chose 23 rumpless and 25 normal Hongshan chickens to localize the potential variation by means of a genome‐wide association study using a high density microarray. A region on the Z chromosome was found to be closely associated with rumplessness in Hongshan chickens. The region, located in gene LINGO2, was approximately 3 Mb away from pseudogene LOC431648. The function of this gene has not yet been studied in birds. Differential expression of the candidate genes in the tail feather follicles was not detected by q‐PCR, which suggests that the rumplessness trait could be attributed to other genetic mechanisms.
