The successive differentiation computer-assisted method for solving well-known scientific and engineering models
Authors: Khuri Suheil , Wazwaz Abdul-Majid 
Published: September 2018

Purpose
Ordinary differential equations (ODEs) are widely used in the engineering curriculum. They model a spectrum of interesting physical problems that arise in engineering disciplines. Studies of different types of ODEs are determined by engineering applications. Various techniques are used to solve practical differential equations problems. This paper aims to present a computational tool or a computer-assisted technique aimed at tackling ODEs. This method is usually not taught and/or not accessible to undergraduate students. The aim of this strategy is to help the readers to develop an effective and relatively novel problem-solving skill. Because of the drudgery of hand computations involved, the method requires the need to use computers packages. In this work, the successive differentiation method (SDM) for solving linear and nonlinear and homogeneous or non-homogeneous ODEs is presented. The algorithm uses the successive differentiation of any given ODE to determine the values of the function’s derivatives at a single point, mostly x = 0. The obtained values are used to construct the Taylor series of the solution of the examined ODE. The algorithm does not require any new assumption, hence handles the problem in a direct manner. The power of the method is emphasized by testing a variety of models with distinct orders, with constant and variable coefficients. Most of the symbolic and numerical computations can be carried out using computer algebra systems.

Design/methodology/approach
This study presents a computational tool or a computer-assisted technique aimed at tackling ODEs. This method is usually not taught and/or not accessible to undergraduate students. The aim of this strategy is to help the readers to develop an effective and relatively novel problem-solving skill. Because of the drudgery of hand computations involved, the method requires the need to use computers packages.

Findings
This method is applied to a variety of well-known equations, such as the Bernoulli equation, the Riccati equation, the Abel equation and the second-order Euler equation, some with constant and variable coefficients. SDM handles linear and nonlinear and homogeneous or nonhomogeneous ODEs in a direct manner without any need to restrictive conditions. The method works effectively to the Volterra integral equations, as will be discussed in a coming work.

Originality/value
The method can be extended to a wide range of engineering problems that are modeled by differential equations. The method is simple and novel and highly accurate.
Line managers’ influence on employee usage of a web-based system for occupational health management
Authors: Frykman Mandus , Lundmark Robert , von Thiele Schwarz Ulrica , Villaume Karin , Hasson Henna 
Published: September 2018

Purpose
The purpose of this paper is to investigate line managers’ influence on employee usage of a web-based system for occupational health management.

Design/methodology/approach
Questionnaires were used to measure line managers’ transformational leadership at baseline and their change-supportive managerial activities during weeks 16–52. Employee initial (weeks 16–52) and sustained (weeks 53–144) use of the web-based system was measured by extracting their frequency of logins to the system from electronic records. Data were collected from six white-collar organizations from 2011 through 2013. Mixed Poisson regressions were used to analyze the influence of transformational leadership and change-supportive managerial activities on employee usage.

Findings
As predicted, line managers’ change-supportive activities influenced the employees’ initial and sustained use of the system. Line managers’ transformational leadership had no direct effect on employees’ use of the system, however transformational leadership was indirectly associated with employees’ initial and sustained use of the system through line managers’ change-supportive activities.

Originality/value
The study adds to the understanding of the role line managers’ play during the implementation of occupational health interventions. The findings suggest that the line managers’ change-supportive activities directed toward the intervention are important for employees’ initial and sustained use of the system. The influence of transformational leadership was indirect, suggesting that line managers may need to direct their leadership behaviors toward the intervention to facilitate implementation.
Biased decisions on IT outsourcing: how vendor selection adds value
Authors: Das Arindam , Grover Dimple 
Published: September 2018

Purpose
This paper aims to investigate the unconscious aspects of information technology (IT) outsourcing decisions.

Design/methodology/approach
The researchers extend the current literature and existing knowledge on the economic aspects of outsourcing decisions in a study on human behaviour and decision-making. Some vulnerabilities related to decision-making on outsourcing have been identified and mechanisms to address these vulnerabilities have been proposed.

Findings
Although IT outsourcing is a widely accepted practice, the vulnerabilities that result from unconscious bias can outweigh the supposed economic gains. However, with support from research in psychology, it is possible to minimize bias and ensure positive value creation when engaging in outsourcing.

Originality/value
The authors argue for a multi-disciplinary approach, for decision-making on outsourcing, that integrates the psychological elements of decision-making with economic value-creation logic. The proposed practitioner-oriented approach is used in conjunction with traditional approaches to decision-making. Specifically, it addresses the uncertainties that may occur when interpreting and inferring information that influences outsourcing decisions.
An appraisal on barriers to implement lean in SMEs
Authors: Yadav Vinod , Jain Rakesh , Mittal Murari Lal , Panwar Avinash , Sharma Milind Kumar 
Published: September 2018

PurposeGlobal competition has intensified pressure on small- and medium-sized enterprises (SMEs) to implement lean. Recently, the debate has converged to the role of lean implementation barriers (LIBs). The purpose of this paper is to contribute to this debate by exploring the LIBs in SMEs through three case studies.Design/methodology/approachA case study approach was employed followed by interpretive structural modelling (ISM) to model the interrelationship among the LIBs.FindingsThis study reveals that lack of management commitment, leadership and resources are the key barriers to lean implementation in SMEs in India. Furthermore, poor communication between different levels of the organisation and inadequate dissemination of the knowledge of lean benefits also creates hindrance in lean implementation. Managerial implications of the identified barriers for lean implementation in SMEs have been discussed.Originality/valueThe research regarding lean implementation in SMEs is scarce. This study is the first attempt of its kind to identify the lean barriers in a small industry setup through mathematical analysis.
Capital spending in local government
Authors: Rivenbark William C. , Afonso Whitney , Roenigk Dale J. 
Published: September 2018

Purpose
The purpose of this paper is to understand the impact of the Great Recession on the capital assets being depreciated and the capital assets condition ratio for the governmental activities of the government-wide financial statements, while identifying possible socioeconomic and financial variables that help explain capital investment behavior in local government.

Design/methodology/approach
Based on capital spending from fiscal year 2005–2006 (FY06) to fiscal year 2012–2013 (FY13) for the governmental activities of 471 North Carolina municipalities as reported on their government-wide financial statements, the authors use a fixed effects model to test our two hypotheses.

Findings
The authors find that most municipalities consistently invested in capital assets before, during, and after the Great Recession but were not able to maintain pace with depreciation. The authors also find that the capital assets being depreciated is affected by numerous socioeconomic and financial variables, while the capital assets condition ratio is not.

Research limitations/implications
The study continues to build on previous research, demonstrating that different results are produced when the analysis is based on local data rather than sub-national data.

Practical implications
An implication from our study that expands across research and practice is that capital investment and capital value are two different dimensions of capital management in local government, which drives research in terms of how this multidimensional concept is specified and drives practices in terms of how this multidimensional concept is approached within annual capital budgets and capital improvement programs.

Originality/value
The study represents one of the first studies that focuses on capital spending in local government based on data from the government-wide financial statements.
Executive ethical decisions initiating organizational culture and values
Authors: Bridges Eileen 
Published: September 2018

Purpose
Ethical decisions determine which individuals and/or groups benefit, and which suffer. Such decisions by executives impact front-line providers directly and customers indirectly; they are important because repercussions in service interactions feel personal. The purpose of this paper is to fill an important gap in the service literature by exploring how high-level executives make ethical decisions, creating values and culture within an organization; the results include testable propositions.

Design/methodology/approach
The research used a grounded theory approach, wherein high-level executives in successful service organizations responded through in-depth interviews. Complete interview transcripts were analyzed using standard qualitative methodology, including open coding to better understand and categorize the data, axial coding to seek out crucial relationships between concepts, and selective coding to develop research propositions.

Findings
Data analysis revealed two groups of interviewees, one more outcome-oriented in decision making and the other more process-oriented. The organizations led by more outcome-oriented executives have strong family-like (or paternalistic) cultures, whereas the organizations led by more process-oriented executives value adaptability and diversity.

Research limitations/implications
The executives interviewed are quite successful; therefore, it is not possible to make inferences about unsuccessful executives or those leading poorly performing organizations. Propositions developed relate that process-oriented executives use both analytical measures and intuition in decision making, whereas outcome-oriented respondents rely more heavily on analytical measures.

Practical implications
Service executives apparently make ethical decisions while focusing either on processes or on outcomes; members of these two groups use different evaluative criteria to identify a successful decision. Decisions relating to people within the organization are perceived by the executives to be especially salient, apparently owing to interpersonal interaction in services.

Social implications
There are inherent social implications when ethical decisions are made, because these decisions determine which individuals or groups benefit, and which suffer.

Originality/value
This research is among the first to interview high-level service executives about their ethical decision making when their choices define culture and values within their organizations. Findings offer a new look at how differences between executives that focus on processes and those that focus on outcomes may shape organizational cultures and lead to consideration of different criteria in making and evaluating decisions.
Zygophyllum albumaqueous extract reduces glycemia and ameliorates lipid profile and oxidative damage in hypercholesterolemic-diabetic rats
Authors: Bahlil Yasmina , Krouf Djamil , Taleb-Dida Nawal 
Published: September 2018

PurposeThis paper aims to study the effects ofZygophyllum album(Za) (Z. album) in hypercholesterolemic-diabetic rats.Design/methodology/approachMale Wistar rats (n= 36) weighing 200 ± 10 g, consumed an experimental diet containing 20 per cent casein were divided into three groups (n= 12). The first group consumed the diet enriched with 1 per cent cholesterol (CH), the second group is rendered diabetic by intraperitoneal injection of streptozotocin (STZ) (35 mg/kg body weight) (D) (DM). The third group is hypercholesterolemic and STZ-induced diabetic (CH-DM); each group was subdivided into two groups (n= 6), non-treated groups (CH, DM and CH-DM) and treated groups supplemented with 1 per centZ. albumlyophilized aqueous extract (CH-Z, DM-Z and CH-DM-Z).FindingsIn CH-DM group,Z. albumdecreases glycemia (−15 per cent) and inversely increases insulinemia (+28 per cent) and Homeostasis Model Assessment of Insulin Resistance (+19 per cent). In liver, total cholesterol (TC) and triacyglycerols (TAG) levels were reduced by −57 per cent and −29 per cent, respectively. In plasma, TC concentration was increased by +20 per cent, whereas those of TAG level were lowered by −56 per cent. Lecithin cholesterol acyl transferase and paraoxonase 1 activities were raised by +45 and +59 per cent, respectively. Inversely, thiobarbituric acid reactive substance levels were lowered significantly in liver, heart, kidney and adipose tissue (p< 0.05). Superoxide dismutase activity was enhanced in liver (+54 per cent), heart (+36 per cent), kidney (+45 per cent) and adipose tissue (59 per cent). Liver glutathione peroxidase (GSH-Px) activity was enhanced by +38 per cent and heart activities of GSH-Px, and glutathione reductase (GSSH-Red) were increased by +25 and +18 per cent. In kidney, GSH-Px activity was reduced by −26 per cent; in reverse, GSSH-Red activity was increased by +14 per cent. In adipose tissue, GSH-Px and GSSH-Red activities were augmented by +35 and +15 per cent.Originality/valueThese results suggest thatZ. albumaqueous extract has antihyperglycemic and antihyperlipemic actions. Also,Z. albumprotects against tissue oxidative damage; therefore, it can help to prevent cardiovascular complications of diabetes combined with hypercholesterolemia.
Implementing accessibility initiatives at the Michigan State University Libraries
Authors: Schroeder Heidi M. 
Published: September 2018

Purpose
This paper aims to describe a variety of accessibility initiatives implemented at the Michigan State University (MSU) Libraries to better support persons with disabilities who want to use and access library services and resources.

Design/methodology/approach
By using two campus accessibility policies to help expand and improve its accessibility efforts, the MSU Libraries implemented accessibility purchasing procedures for e-resources; drafted a five-year accessibility plan, which launched an extensive multi-year staff accessibility training plan and detailed plans for content accessibility and accessibility investment; dedicated additional library staff positions and time to accessibility; drafted an accessibility statement and website documentation; established an in-house remediation service; increased library web page and collection remediation; and began leading efforts related to vendor e-resource accessibility in the Big Ten Academic Alliance library consortium.

Findings
As a result of these many accessibility initiatives, the MSU Libraries has thought strategically about and taken action on constantly improving its accessibility in a variety of areas; provided or hosted 29 staff accessibility training sessions; implemented new accessibility positions, roles and services; and helped influence and improve library e-resource accessibility, especially through its leadership in the Big Ten library consortium.

Originality/value
Most libraries strive to provide welcoming access to information and library services for all users, including persons with disabilities, but resources and literature on comprehensive accessibility initiatives in academic libraries are somewhat limited. The library accessibility initiatives implemented by a large, academic research library shared in this paper will hopefully contribute to the much-needed library and information science literature on this topic.
EBSCO information services usability study on accessibility
Authors: Power Jill A. 
Published: September 2018

Purpose
Last spring, EBSCO Information Services conducted a usability study with several students with visual impairments. The goal was to understand how these students conduct research and identify areas for improvement of EBSCO Discovery Service™ such that it would meet the needs of all potential users. EBSCO Discovery Service™ provides users with means of accessing all of an institution’s internal (library) and external (database vendors) information resources through a single search. The purpose of this paper is to outline the findings of this research and the applicability to the design of any online resource.

Design/methodology/approach
Using the Bentley University’s user experience lab to facilitate the study and the Carroll Center for the Blind in Newton, Massachusetts, for recruitment of college students, EBSCO solicited feedback on how students conduct research on the Web in general, as well as their experience using EBSCO’s discovery service. The study involved a structured interview with eight visually impaired students from the Boston area, who had recently been enrolled in a college course. The students were also asked to complete certain tasks using the discovery service and report out as they completed each activity.

Findings
The findings demonstrated that for the most part, students with visual impairments engaged in research on the Web and within the discovery service in a similar manner to sighted students. They used the same standard search sites, expected the same layout conventions for results’ lists and filters and wanted easily savable full-text documents. Main differences involved their ability to navigate in a similar way to sighted users. Elements that one could skip over quickly as a sighted user were more of a hindrance to those relying on a screen reader. Additionally, improved descriptions for graphics, functions and form fields were noted as opportunities for improvement. For those with low vision, using screen magnifiers, modal boxes and hover features or other unexpected changes on the site proved to be challenging.

Research limitations/implications
This study focused only on students with visual disabilities. There are many other print disabilities that were not explored such as color blindness, cognitive disabilities or learning disabilities. All the students were in their 20s and had experience conducting research and using library or research-related search sites. Many of the findings highlighted areas of improvement that would benefit all students.

Originality/value
A study on students with visual disabilities using assistive technologies as they completed research tasks on a discovery system has not been studied before. Guidelines and audits do not provide a complete picture as to whether a website is fully accessible. It is only by working with actual users that insight into what it means to create a truly accessible experience can be gained.
Postformalism and affect in research: autoethnography, truth and estrangement
Authors: Earhart Robert 
Published: September 2018

Purpose
This paper aims to investigate learning, relatedness and ethics in research as question of personal responsibility. Positivist and postformalist approaches to research are considered in light of the perspectives and experiences of the researchers themselves.

Design/methodology/approach
These questions are considered through an autoethnography of postformalism based on the doctoral research of the author.

Findings
The conclusion of this work is that research inclusive of affect, reflexivity and the context in which the research takes place, allows for insights into organizational ethics that would otherwise not be possible. However, these approaches come at a personal and professional risk for the researcher. Truly authentic postformalist research demands a degree of hazard for the researcher, becoming both a way of living and an ethical choice.

Originality/value
This paper addresses the ongoing debate concerning the use of first-person research, in general, which has not received a warm welcome as a “serious” form of research, especially in the more conventional methodological circles. The conclusions open up new considerations for first-person methods, such as autoethnography.
e-Waste trading zones and the economy of greening
Authors: Stowell Alison F. , Brigham Martin 
Published: September 2018

PurposeIn the context of the environmental impacts caused due to the increasing volumes of discarded technologies (e-Waste), this paper aims to critically evaluate whether environmental policy, the Waste of Electronic and Electrical Equipment (WEEE) legislation in particular can contribute to a shift in logic from neoliberal growth to green growth.Design/methodology/approachDrawing upon empirical research, this paper shows how three computer waste organisations evolve through the imbrication of pre- and post-policy logics in collaborative and heterogeneous ways to create an “economy of greening”.FindingsExtending the concept of a fractionated trading zone, this paper demonstrates the heterogeneous ways in which computer sourcing is imbricated, providing a taxonomy of imbricating logics. It is argued that what is shared in a fractionated trading zone is a diversity of imbrications. This provides for a nuanced perspective on policy and the management of waste, showing how post-WEEE logics become the condition to continue to pursue pre-WEEE logics.Research limitations/implicationsThis research focuses on three organisations and the EU 2003 and UK 2006 versions of the WEEE legislation.Practical implicationsThe research findings have important implications, more specifically, for how e-Waste policy is enacted as an “economy of greening” to constitute managerial and organisational adaptation needed to create a sustainable economy and society.Originality/valueThis paper’s contribution is threefold. First, theoretically, the literature on trading zones and imbrication is extended by considering how they can complement one another. Our focus on imbrication is a “zooming in” on the managerial and organisational implications and dynamics of a trading zone. Second, the literature on imbrication is added to by identifying a diverse range of imbricating logics that can be used to discern a more nuanced understanding of the translated effects of policy. Last, these ideas are ground in a relevant empirical context – that of e-waste management in the UK, providing a deeper knowledge, over time, of specific actors’ translations of policy into organisational practices.
