Robust calibration of hierarchical population models for heterogeneous cell populations
Authors: Loos Carolin , Hasenauer Jan 
Published: July 2019

AbstractCellular heterogeneity is known to have important effects on signal processing and cellular decision making. To understand these processes, multiple classes of mathematical models have been introduced. The hierarchical population model builds a novel class which allows for the mechanistic description of heterogeneity and explicitly takes into account subpopulation structures. However, this model requires a parametric distribution assumption for the cell population and, so far, only the normal distribution has been employed. Here, we incorporate alternative distribution assumptions into the model, assess their robustness against outliers and evaluate their influence on the performance of model calibration in a simulation study and a real-world application example. We found that alternative distributions provide reliable parameter estimates even in the presence of outliers, and can in fact increase the convergence of model calibration.HighlightsGeneralizes hierarchical population model to various distribution assumptionsProvides framework for efficient calibration of the hierarchical population modelSimulation study and application to experimental data reveal improved robustness and optimization performance
Refugees’ inclusion at work: a qualitative cross-level analysis
Authors: Knappert Lena , van Dijk Hans , Ross Veerle 
Published: July 2019

Purpose
Refugees’ inclusion at work is critical for the individual, for employers and for the receiving societies. Yet, refugees are often disadvantaged in working life or are being excluded from the labor market altogether. The purpose of this paper is to examine barriers and facilitators to refugees’ inclusion at work at the individual, organizational and country level, and pay particular attention to how the three levels relate to each other in shaping inclusion and exclusion of refugees at work.

Design/methodology/approach
The authors conducted 18 interviews with employed refugees, employers and experts from governmental and non-governmental institutions in the Netherlands.

Findings
Based on the theoretical structure, 13 themes emerged from the interview material – 5 themes at the individual level, 4 at the organizational level and 4 at the country level. The authors also found indicators for an interplay of barriers and facilitators across levels.

Research limitations/implications
This is a small study conducted in the Netherlands, providing several starting points for future research.

Practical implications
The authors provide recommendations for refugees, employers and policy makers aimed at addressing barriers and leveraging facilitators of refugees’ inclusion at work.

Originality/value
The organizational level, which diversity research has shown to affect minority group members’ inclusion at work, is rarely taken into account in refugee research. Based on the cross-level analysis, the authors identify patterns of interplay between the three levels and provide a relational framework of refugees’ inclusion at work.
Disruptive technologies and career transition strategies of middle-skilled workers
Authors: Chen Quan , Wang Jing-An , Ou Ruiqiu , Sun Junhua , Chang Li-Chung 
Published: July 2019

Purpose
Disruptive technologies often disrupt the careers of middle-skilled workers. The purpose of this paper is to investigate career transition strategies of middle-skilled workers that partially continue or expand their careers under the condition of disruptive technologies.

Design/methodology/approach
This paper established a conceptual framework of career transition strategies for middle-skilled workers by integrating the existing studies of disruptive technologies, technological trajectory transition, boundaryless and protean careers, and careers as repositories of knowledge.

Findings
The authors proposed three types of career transition strategies to partially prolong middle-skilled workers’ careers, namely, industry-oriented transition strategy which refers to a transfer to other occupations in the original industry, technology-oriented transition strategy which refers to a transfer to occupations with original technical skills in other industries, and comprehensive transition strategy which refers to a transfer to other occupations in the related industries. Further, this paper discusses the external conditions and individual competencies for each career transition strategy, and timing for implementing a career transition strategy from the perspective of the technology life cycle.

Originality/value
This paper focused on sustainable careers of middle-skilled workers under the condition of disruptive technologies, which received very little attention from the current literature. The findings also suggested for middle-skilled workers to develop a sustainable or long-term career in the current era of many disruptive technologies. The findings may also imply on how firms and government should contribute to help workers on handling scenarios of technological disruption.
Role context change and actionable career knowledge for practicing managers
Authors: Laud Robert , Arevalo Jorge , Johnson Matthew 
Published: July 2019

PurposeThe purpose of this paper is to examine the relevancy of traditional managerial role frameworks as perceived by practicing managers, and to identify emerging role requirements or skills required for career success.Design/methodology/approachA mixed-methods approach was conducted including survey research, empirical analysis and semi-structured consensual qualitative research interviews with 259 managers from 200 organizations.FindingsThis study demonstrates a widening gap between entrenched organization role constructs and emerging practice-driven role skills. The empirical analysis indicated little to moderate relevancy of traditional role constructs by practicing managers while follow-up interviews revealed new role requirements driven by contemporary market realities and changing managerial motivations. The findings suggest that inclusion of new practice-driven role requirements or skills are likely to be mutually beneficial and influence career success.Research limitations/implicationsThe findings may limit the ability to generalize without further comparative analysis in similar/dissimilar economies.Practical implicationsIndividuals will benefit by the inclusion of revised role requirements and policies that are designed to support employee-driven needs and “employability” skills that are more consistent with a careerist orientation. The organization will also benefit by having a more highly skilled workforce in key areas of competitive advantage including networking, innovation and opportunity identification.Originality/valueThe value of this examination is twofold. First, it extends the understanding of the diminishing relevancy of traditional managerial roles within a context of major global and social transformation. Second, it underscores the growing importance of “employability” skill sets and capabilities for managerial career aspirants facing new market realities.
The importance of horizontal fit of university student jobs for future job quality
Authors: I.J.M. Van der Heijden Beatrice , Le Blanc Pascale M. , Hernandez Ana , Gonzalez-Roma Vicente , Yeves Jesus , Gamboa Juan P. 
Published: July 2019

Purpose
The purpose of this paper is to gain a better understanding of the antecedents of the quality of graduates’ jobs when they enter the job market after university graduation.

Design/methodology/approach
Survey data collected from 173 Spanish bachelor and master’s degree university graduates at two time points (two months before and six months after graduation, approximately) were analyzed by means of path analysis.

Findings
A moderated mediation model was tested, where the relationship between the horizontal fit (HF) between the university degree subject and the student’s job and the quality of the graduate’s job after graduation is mediated by self-perceived employability and moderated by the time devoted to a student job. Results showed that the relationship between HF and job quality was partially mediated by self-perceived employability. However, contrary to the proposed hypothesis, this relationship did not depend on the time devoted to a student job.

Originality/value
This study contributes to improving the understanding about how and why university students’ work experience is related to the quality of their jobs as fresh graduates.
Physis, thaumazein and policy thinking: on another “time” to think educational policy
Authors: Chua Jude 
Published: July 2019

Purpose
The purpose of this paper is to suggest that the mechanics of the neoliberal mindset is governed paradigmatically by a peculiar notion of “time,” which leads, in turn, to a kind of amoral consequentialism that projects meaninglessly and amorally into the future. The author proposes, in comparison, the pre-modern and ancient sense of the temporal which has the potential to yield moral insights for guiding policy thinking.

Design/methodology/approach
The author employs a philosophical approach and historical approach. The authors analyze philosophically the notion of the temporal in the consequentialist neoliberal agency, and draws on continental, ancient and medieval philosophical sources of temporality to develop an alternative.

Findings
The author argues that a rich notion of the temporal can be retrieved from medieval sources. This notion of the temporal is located in our experience of changing embodied beings, or physis, and gives rise to thuamazein or awe, which shows moral insights. The latter is a valuable source of guidance in policy thinking.

Research limitations/implications
This paper also suggests that epistemological commitment to an authority as numbers, feeding a policy as numbers, needs to be challenged. This paper does not draw on empirical data but nevertheless aspires to develop a thoughtful conceptual case on behalf of its conclusions.

Practical implications
A moral, neoliberal consequentialism is harmful to professional agencies. This paper offers a different way to think policy that puts what truly matters in front of us.

Social implications
Neoliberalism breeds the terrors of performativity that forgets what as a society we need to aim for on behalf of happiness, and instead drives us to compete without restraint after particular quantitative achievements. By challenging this paradigm, it is possible to offer policy thinking a different set of conceptual tools with which to think ourselves out of this performative irrationality.

Originality/value
This paper retrieves a medieval notion of time that is related with the showing of moral insights, opposed to amoral neoliberal consequentialism. In this way, there is a proposal of an alternative to neoliberalism, and not merely the worry of its damaging effects. It is also an original developmental study of Heidegger’s retrieval of ancient philosophy’s sense of temporality and its connection with ethics in the light of the resources in medieval philosophy.
The social representation of success in IT projects
Authors: Joia Luiz Antonio , Melon Marcela 
Published: July 2019

PurposeThe purpose of this paper is to unveil the perception of information technology (IT) professionals in Brazil regarding the success of IT projects.Design/methodology/approachBy using the social representation theory and the words evocation technique, data were collected from IT professionals in Brazil, being subsequently processed so as to identify the central nucleus of the social representation of the success of IT projects for IT professionals in Brazil.FindingsIT professionals in Brazil perceive the central core of the social representation of the success of IT projects as formed by “satisfaction” and “scope.” Furthermore, while a considerable amount of IT professionals in Brazil still consider cost, quality and time as relevant factors for the success of IT projects, they do not consider them the most important factors. Moreover, these professionals overlook the financial dimension of the success of IT projects.Research limitations/implicationsErrors of inference may have been made during the categorization of the words evoked. Furthermore, the sample adopted refers exclusively to IT professionals in Brazil, which limits the universality of the work.Practical implicationsOrganizations and project management associations must take into account the utmost importance of customer satisfaction for the success of IT projects. Besides, these associations must develop IT project success criteria that account for the financial, business and strategic impact of the success of IT projects in organizations.Originality/valueIT project success is perceived by IT professionals in Brazil merely from the adherence to scope and customer satisfaction dimensions, leaving aside the importance of project profitability and the strategic impacts of same in the performance of organizations, as well as their future.
Self-efficacy and employee job performance
Authors: Na-Nan Khahan , Sanamthong Ekkasit 
Published: July 2019

PurposeRelationship between self-efficacy (SE) and employee job performance (EJP) is of vital importance for organizations but remains unclear. A more comprehensive understanding demonstrated that perceived workplace support (PWS), motivation to transfer (MT) and transfer of training (TT) had mediating effects on the relationship between SE and EJP. The paper aims to discuss these issues.Design/methodology/approachEmpirical data were garnered from 250 alumni of the Engineering Faculty, Rajamangala University of Technology Thanyaburi, Thailand through a questionnaire requesting 62 answers. A research outline was proposed, with structural equation modeling utilized to test the framework, determine the direct influence of SE on EJP and also any indirect influences on EJP through PWS, MT and TT variables.FindingsSE increased EJP through enhancing PWS, MT and TT. In addition, PWS, MT and TT were determined as partial mediator factors of SE on EJP.Originality/valueEmpirical evidence was presented as two mechanisms that helped to explain the effect of SE on EJP. To enhance EJP, organizations should consider contributions associated with SE, PWS, MT and TT when designing and implementing transfer training for effective EJP.
Tool life prediction by RSM for cryogenic milling of inconel 718
Authors: Abdul Halim Nurul Hayati Binti , Che Haron Che Hassan , A. Ghani Jaharah , Azhar Muammar Faiq 
Published: July 2019

Purpose
The purpose of this study is to present the tool life optimization of carbide-coated ball nose milling inserts when high-speed milling of Inconel 718 under cryogenic CO2 condition. The main aims are to analyze the influence level of each cutting parameter on the tool life and to identify the optimum parameters that can lengthen the tool life to the maximum.

Design/methodology/approach
The experimental layout was designed using Box–Behnken RSM where all parameters were arranged without combining their highest and lowest values of each factor at the same time. A total of 29 milling experiments were conducted. Then, a statistical analysis using ANOVA was conducted to identify the relationship between the controlled factors on tool life. After that, a predictive model was developed to predict the variation of tool life within the predetermined parameters.

Findings
Results from the experimental found that the longest tool life of 22.77 min was achieved at Vc: 120 m/min, fz: 0.2 mm/tooth, ap: 0.5 mm and ae: 0.2 mm. ANOVA suggests the tool life of 23.4 min can be reached at Vc: 120.06 m/min, fz: 0.15 mm/tooth, ap: 0.66 mm and ae: 0.53 mm. All four controlled factors have influenced the tool life with the feed rate and radial depth of cut (DOC) as the major contributors. The developed mathematical model accurately represented the tool life at an average error of 8.2 per cent when compared to the actual and predicted tool life.

Originality/value
These experimental and statistical studies were conducted using Box–Behnken RSM method under cryogenic CO2 condition. It is a proven well-known method. However, the cooling method used in this study is a new technique and its effects on metal cutting, especially in the milling process of Inconel 718, has not yet been explored.

Library and information science and sustainable development: a structured literature review
Authors: Meschede Christine , Henkel Maria 
Published: July 2019

Purpose
Awareness on and importance of sustainability in all aspects of our lives is becoming more and more important. The question arises, how – not if – scientists can contribute to a sustainable development. As information plays an important role for development, information scientists should be included in this debate. However, is there a sustainable information science or an information science of sustainability? The purpose of this paper is to perform a mapping of publications in library and information science (LIS) directly dealing with sustainability and sustainable development.

Design/methodology/approach
A structured literature review was conducted, enhanced by bibliometric analyses. For this purpose, 102 LIS journals and conferences were considered. The authors identified 81 publications dealing with sustainability and sustainable development and analyzed the concrete contents and methodological approaches of these.

Findings
A large proportion of articles could be found dealing with sustainable development and libraries. Other publications focus on information and communication technology or information systems. Only few articles deal with further topics like government, urban development or scientific output.

Research limitations/implications
Sustainability and sustainable development are complex topics. This work only considers literature whose title or keywords contain the string sustainab*.

Originality/value
The presented work helps to get an overview on sustainability research and activities in the LIS field and additionally, potential research gaps may be identified. The authors call for more research in this area and concrete ideas to help develop a sustainable future.
Information seeking abroad: an everyday-life study of international students
Authors: Hertzum Morten , Hyldegård Jette Seiden 
Published: July 2019

Purpose
The purpose of this paper is to investigate how four international students at a Danish university cope with their study-related and everyday information needs, behaviorally as well as affectively, and how their information seeking blends with their cross-cultural adaptation.

Design/methodology/approach
Each of the four participants contributed ten diaries and took part in three interviews during the first semester of their stay.

Findings
International students’ information needs and seeking behavior are shaped by their host university but also by cross-cultural, personal and situational issues. While the cross-cultural issues set international students apart from domestic students, the personal and situational issues create individual differences that call for more individually tailored support. The studied international students lacked information about both study-related and everyday issues. These two types of issues were intertwined and experienced as equally stressful. However, study-related information needs were more important, whereas everyday information needs were more difficult to resolve. In addition, participants tended to feel on their own when it came to finding needed information, but studying abroad also had elements of personal growth in meeting life’s challenges.

Research limitations/implications
More participants are needed to investigate how international students’ information seeking evolves over time.

Originality/value
This study contributes detailed information about international students’ study-related and everyday information seeking during their first semester abroad. The study has implications for everyday-life studies of international students’ information behavior and the international classroom in general.
Influences of technological attributes on sourcing of manufacturing technologies in developing countries
Authors: Cabrera Rony , González Domingo 
Published: July 2019

Purpose
As part of a new focus on a better balance of investment in innovation activities in developing countries, this study aims to understand the effects of technological attributes (technological complexity and type of technology) on manufacturing technology sourcing (whether firms choose either internal development or external sources).

Design/methodology/approach
Multiple-case studies were conducted in the Peruvian manufacturing sector.

Findings
The authors found that, across Peruvian manufacturing firms, they develop a certain manufacturing technology related to their capabilities. However, when the total cost of acquisition is lower than internal costs of developing technologies, they will choose external sources, regardless of their capabilities and complexity of the technology. In addition, analysis of the type of technology indicated that the pursuit of simultaneous exploration and exploitation occurs when firms use external sources rather than internal.

Research limitations/implications
This study has the limitation that data have been collected years after the decision-making process; the results are based solely on the authors’ analysis using the case of Peruvian industry, and they do not track the impact on the performance of manufacturing technology decisions.

Practical implications
The findings have important implications for technology managers of South American manufacturing firms that are decision makers in the sourcing of new manufacturing technologies.

Originality/value
The results of this study provide literature with insights into technology sourcing strategy in developing countries and the importance of progress in transitioning to technological innovation and catchup.
