Security capability and logistics service provider selection: an adaptive choice study
Authors: Williams Zachary , Garver Michael S. , Richey Jr Robert Glenn 
Published: May 2019

PurposeThe influence of security practices is increasingly common in the supply chain management and logistics literature. However, an under-researched area exists within the logistics service provider (LSP) selection process. The purpose of this paper is to introduce a security capability into the LSP selection process. Specifically, this research seeks to understand partner willingness to compensate and collaborate with service providers that possess a security capability.Design/methodology/approachAdaptive choice modeling is adopted to assess the influence of a security capability in the LSP selection process. This study represents the first use of this method in supply chain management and logistics research. Cluster analysis is also performed to uncover specific buyer segments along with traditional regression-based significance testing and counting analysis.FindingsThe findings indicate that security can have an important influence on the LSP selection process. In particular, the findings note a willingness to pay for a security capability in LSP selection. Applying segmentation techniques to the findings, three LSP buying segments are determined, each placing different importance and value on LSP capabilities.Practical implicationsThis research notes an ongoing provider deficiency in security offerings. Partner firms sometimes maintain a cost focus, but others show a willingness to pay higher prices for access to partners with a security capability. Key practitioner findings include the need to include security with other traditional selection variables. The study walks the researcher and manager through the development of segments based on LSP capabilities.Originality/valueThis manuscript investigates logistic service provider selection. The authors detail an advanced form of conjoint analysis, adaptive conjoint modeling, for first time consideration. Additionally, this is the first study to integrate security into the LSP selection process. This is also the first study to identify a willingness to pay for a security capability.
Strategic scenario analysis combining dynamic balanced scorecards and statistics
Authors: Supino Enrico , Barnabè Federico , Giorgino Maria Cleofe , Busco Cristiano 
Published: May 2019

Purpose
The purpose of this paper is to explore the way in which system dynamics (SD) can enhance some key success factors of the balanced scorecard (BSC) model and support decision-makers, specifically in analyzing and evaluating the results of hypothetical scenarios. Moreover, the paper aims to emphasize the role played by statistics not only in validating the SD-based BSC, but also in increasing managers’ confidence in the model reliability.

Design/methodology/approach
The paper presents a case study, developed according to an action research perspective, in which a three-step approach to the BSC implementation was followed. Specifically, the first step requires the development and implementation of a “traditional” BSC, which is refined and transformed into a simulation SD model in the second step. Last, the SD-based BSC is combined with statistics to develop policy making and scenario analysis.

Findings
The integration of BSC and SD modeling enables the development of a comprehensive approach to strategy formulation and implementation and, more importantly, provides a more reliable basis upon which to build and test sound cause-and-effect relationships, within a specific BSC. This paper exemplifies how an SD-based BSC can be used – and perceived reliable – to evaluate different scenarios and mutually exclusive policy effects in a multidimensional approach. In particular, this study illustrates how to forecast and depict trends for financial and non-financial indicators over the simulation period, with reference to three different scenarios.

Originality/value
This paper contributes to the ongoing debate on the BSC by exploring whether a combination of SD and statistics may enhance the BSC system’s advantages and facilitate its implementation process and use for decision-making and scenario analysis.
The influence of ERP system usage on agile capabilities
Authors: Almahamid Soud 
Published: May 2019

PurposeSynthesising theories of enterprise resource planning (ERP), psychological empowerment and agile capabilities, the purpose of this paper is to build and test a novel theoretical model linking ERP system usage with agile capabilities via users’ psychological empowerment in Jordanian commercial banks.Design/methodology/approachA questionnaire was developed to collect the relevant data based on the extant literature. The population of this study consisted of all ERP system users working at Jordanian commercial banks in Amman City. The questionnaire was circulated to a purposive sample of actual users of ERP systems for two reasons. First, it was not possible to obtain a list of actual ERP users in each bank, for security and privacy reasons. Second, actual users of ERP systems are the most relevant source of information.FindingsThe results revealed that ERP system usage has a significant positive impact on both agile capabilities and users’ psychological empowerment. The results also showed that users’ psychological empowerment has a significant positive impact on agile capabilities. In addition, the results provide empirical evidence that users’ psychological empowerment plays a mediating role between ERP system usage and all agile capabilities except responsiveness. Furthermore, by adding users’ psychological empowerment to the original research model, the study demonstrates a good predictive relevance for agile capabilities.Research limitations/implicationsThe study only focuses on Jordanian commercial banks; it is a cross-sectional study; and the study data were subjective, reflecting respondents’ opinion on specific time.Practical implicationsPractitioners struggle to ensure high levels of ERP usage by target users, to achieve implementation success and to achieve expected benefits. More often, practitioners have focused on the ERP system project team, vendors and technical issues, but have ignored the human side of the implementation process. Hence, they have failed to acknowledge the role of psychological empowerment in ERP system acceptance and success. Practitioners are advised to promote the ERP system as a facilitation and empowerment tool for users rather than a means of surveillance and control. Moreover, practitioners can avoid high rates of ERP failure in the adoption and post-adoption stages by changing the aim of the ERP system introduction from increasing efficiency and visibility to enhancing users’ psychological empowerment. Practitioners can leverage agile capabilities to respond to changes in the business environment by ensuring healthy psychological empowerment for all ERP users to use the system to its full capacity and to exchange information between functional units in real time. Practitioners must ensure users’ psychological readiness to use the system before the system goes live.Originality/valueThe study developed and tested a new research model using the SmartPLS approach in a novel context.
The role of relational norms in linking inter-partner learning and IT co-sourcing performance
Authors: Hsu Shu-Mei , Chou Tzu-Chuan , Lee Gwo-Guang , Kuo Ren Zong 
Published: May 2019

PurposeThe purpose of this paper is to identify the antecedent factors that foster and sustain the development of relational norms from a social exchange process perspective and articulates the mediating effect of relational norms on the relationship between inter-partner learning (IL) and IT co-sourcing performance.Design/methodology/approachA total of 197 usable questionnaires were returned from 1,000 Taiwan enterprises. Results from a partial least squares method supported the hypothesis that relational norms serve as dependent variable (to IL) and independent (mediating) variable (to IT co-sourcing performance).FindingsThe empirical results show that IL positively effects partnership identity and collaboration, while both significantly mediate the effects of IL on IT co-sourcing performance.Research limitations/implicationsThe research implications confirm that the relational norms which IT co-sourcing parties must include both attitudes and behavior simultaneously, and that IT co-sourcing will not produce good performance without both parties developing shared attitudes and collaborative behavior.Practical implicationsRelational norms can play a critical mediation role to help ensure that both parties reach their common goals successfully and prevent the risk of their effort to cooperate together falling apart. Therefore, project managers have to take account of the importance of relational norms on inter-organizational cooperation or strategic alliances.Originality/valueThis study creates opportunities for further cross-disciplinary studies of inter-firm co-sourcing project especially with regard to relational norms and knowledge sharing.
Adoption, adaptation, and use of mobiles by university students: a Central American example
Authors: Aguirre Juan , Chaves Sindy , Burban Karen 
Published: May 2019

Purpose
The purpose of this paper is to identify the actual uses of smartphones for university students while they are in the university, whether in the classroom or outside, to facilitate the use of mobile technologies in the university and in classroom activities.

Design/methodology/approach
The site was the main campus of a university with a population of 10,000 undergraduate students; a convenience sample of 370 students was estimated for 246 usable surveys, with 95% confidence interval and 6.12 percent error. The proposed conceptual framework is based on the unified theory of technology acceptance. The instrument was developed on the basis of the literature and it was validated through a qualitative–quantitative process. The data were collected fact-to-face and the analysis consisted of the estimation of a general profile, mean and standard deviation and the development of the ordinal logistic regression model to test the hypothesis. Minitab 16 was the program used for the calculations.

Findings
The instrument was found to be acceptable with a 0.90 α. The uses associated with the academic activities are: p8_1 search what I do not understand in the class, p5_1 read digital books, pdf and other documents, p9_1 study, p11_1 share course information and p2_1 take photos of class blackboard and another type of materials. For non-academic uses, the uses were: p14 calendar, p4 listening to music, p9 telephone calls and p7 interacting with new students. The adaptation of mobiles to university education has to harmonize students’ use, professors’ objections and institutional concerns; therefore, four elements are needed before a decision is made: professors’ training, teaching material development, infrastructure adaptation and a sound plan.

Research limitations/implications
The selection of students was a convenience sample; therefore, the results cannot be extrapolated beyond the sample.

Practical implications
The study clarifies the traditional idea popular in the area, that is, students use the mobile only for entertainment, and suggests ways to managerially deal with the issue in an orderly fashion, by investing in human capital, infrastructure and electronic teaching tools.

Originality/value
The value is that the findings provide some ideas regarding the uses of smartphones for university students while they are in the university; such information can be used to orient strategies to develop educational uses of the smartphone.
Twofold relationship dynamics of supplier’s knowledge sharing
Authors: Suh Taewon , Jung Jae C. , Zank Gail M. , Arend Richard J. 
Published: May 2019

PurposeAssuming that supplier knowledge can either strengthen the partnership by nurturing the commitment and trust between partners or allow the buyer to be more calculative, this study aims to propose two types of knowledge sharing in supplier relationship – a type benefiting the partnership and another privately benefiting only one partner.Design/methodology/approachUsing structural equation modeling and a surveyed dataset from 352 buyer–supplier partnerships, this study tested the research model of dual mechanism, where two types of knowledge sharing co-exist and have opposite effects on partnership longevity.FindingsThis study found that the two types of knowledge sharing create divergent effects on partnership continuation. For a buyer firm developing supplier knowledge, its supplier firm reciprocates by sharing knowledge with the buyer. While relation-specific knowledge promotes partnership longevity through developing trust, institutionalized knowledge hampers partnership longevity.Research limitations/implicationsFindings overall indicate that knowledge plays a more instrumental role in sharing knowledge in a buyer–supplier relationship, and alternative forces simultaneously work in the partnership. Although this study explicates two mediating mechanisms for the effect of supplier knowledge, there remain many unknown aspects of the effect.Practical implicationsFrom the buyer’s perspective, it is possible its institutionalized knowledge can facilitate its relationship with a current supply chain partner so that it can gain more benefits from the relationship. From the supplier’s perspective, caution should be exercised in selecting the type of knowledge to share.Social implicationsThis study may have a broad impact on public policy by theorizing and testing why some partnerships last longer/shorter than others in association with the dynamics of the relationship initiated by one’s relational knowledge and the other’s knowledge sharing.Originality/valueWhat this study contributes to involves the theorizing and testing the effects of the dual mechanism of knowledge sharing on partnership longevity. This study provides an example of a private investment in knowledge that is reciprocated with each type of knowledge – benefiting the partner and also benefiting the focal buyer firm.
Follower emotional intelligence
Authors: Rajesh J. Irudhaya , Prikshat Verma , Shum Paul , Suganthi L. 
Published: May 2019

PurposeThe purpose of this paper is to understand the impact of transformational leadership (TL) on follower emotional intelligence (EI) and examine the potential mediation role played by follower EI in the relationship between TL and follower outcomes (i.e. growth satisfaction in the job and job stress (JS)).Design/methodology/approachData were obtained through survey using questionnaire collected from 908 employees who worked across six different sectors, i.e. manufacturing, IT, healthcare, hospitality, educational and public services in Southern India. The mediation model proposed in this study was tested using structural equation modelling and bootstrapping method.FindingsThe relationship between TL and Follower EI was significant. Follower EI was found to partially mediate the relationship between TL and followers’ growth satisfaction in job. Contrary to expectations, the follower EI did not significantly predict JS in this study and hence the follower EI did not mediate in the proposed model. However, follower EI and growth satisfaction in the job jointly mediated the relationship between TL and follower JS fully.Research limitations/implicationsSelf-report bias about supervisors’ TL behaviours and followers’ own EI assessment and collection of data from the mono-source (subordinate self-report) might have impacted the results of this study. Moreover, some items were negatively worded and reverse coded as cognitive speed bumps to restrain the respondent’s tendency to rush through answering the survey questionnaire.Practical implicationsThis study established a partial and joint mediation of follower EI on the relationship between TL and follower outcomes. Basing on these findings, this study highlights the need for the practitioners to better understand the importance of EI training for the leaders in the organisations for obtaining better outcomes in the followers.Social implicationsThe study establishes the fact that the attunement of transformational leaders’ EI and follower EI help leaders as well as followers to guide their behaviour towards positive outcomes.Originality/valueThis study is among the first to examine the impact of TL on follower EI and the potential mediation of follower EI between TL and follower outcomes. From a theoretical perspective, this study is one step closer to fully understand the intervening process between TL and follower outcomes.
Do latex and resin canals spur plant diversification? Re‐examining a classic example of escape and radiate coevolution
Authors: Foisy Michael R. , Albert Loren P. , Hughes Daniel W. W. , Weber Marjorie G. 
Published: May 2019

AbstractThe association between increased lineage diversification rates and the evolution of latex and resin canals is widely cited as a paradigmatic example of Ehrlich and Raven’s ‘escape‐and‐radiate’ hypothesis of co‐evolution. However, it has been over a quarter‐century since the original study, and updates to phylogenetic comparative methods, plant molecular systematics, and phenotypic data warrant a reassessment of this classic finding.We gathered data on latex and resin canals across 345 families and 986 genera of vascular plants and conducted a multi‐scale test of the association between these traits and lineage diversification rates. At a broad scale (across clades), we used sister‐clade comparisons to test whether 28 canal‐bearing clades had higher net diversification rates than their canal‐lacking sister clades. At a finer scale (within clades), we used ancestral state reconstructions and phylogenetic models of lineage diversification rates to examine the relationship between trait evolution and the timing of diversification rate shifts in two better‐characterized clades – Araceae and Papaveraceae.At both scales of our analyses we found poor support for the predicted relationship between diversification and the evolution of latex and resin canals. Follow‐up analyses clarified that the qualitative change between our results and those of the Farrell et al.’s classic study is not the result of different phylogenetic comparative methods. Instead, the differences are attributable to updates to plant systematic hypotheses and new data on laticifers and resin canal presence/absence.Synthesis.Our updated study reveals that there is no longer strong evidence for latex or resin canals as general, consistently replicable drivers of species diversity across plants. However, we cannot rule out a relationship in all groups. We therefore argue that theoretical and empirical work aimed at understanding ecological factors that condition ‘escape‐and‐radiate’ dynamics will allow for more nuanced tests of the hypothesis in the future.
Macroevolutionary patterns in overexpression of tyrosine: An anti‐herbivore defence in a speciose tropical tree genus, Inga (Fabaceae)

Abstract

Plant secondary metabolites are a key defence against herbivores, and their evolutionary origin is likely from primary metabolites. Yet for this to occur, an intermediate step of overexpression of primary metabolites would need to confer some advantage to the plant. Here, we examine the evolution of overexpression of the essential amino acid, L‐tyrosine and its role as a defence against herbivores.

We examined overexpression of tyrosine in 97 species of Inga (Fabaceae), a genus of tropical trees, at five sites throughout the Neotropics. We predicted that tyrosine could act as an anti‐herbivore defence because concentrations of 4% tyrosine in artificial diets halved larval growth rates. We also collected insect herbivores to determine if tyrosine and its derivatives influenced host associations.

Overexpression of tyrosine was only present in a single lineage comprising 21 species, with concentrations ranging from 5% to 20% of the leaf dry weight. Overexpression was pronounced in expanding but not in mature leaves. Despite laboratory studies showing toxicity of L‐tyrosine, Inga species with tyrosine suffered higher levels of herbivory. We therefore hypothesize that overexpression is only favoured in species with less effective secondary metabolites. Some tyrosine‐producing species also contained secondary metabolites that are derived from tyrosine: tyrosine‐gallates, tyramine‐gallates and DOPA‐gallates. Elevated levels of transcripts of prephenate dehydrogenase, an enzyme in the tyrosine biosynthetic pathway that is insensitive to negative feedback from tyrosine, were found only in species that overexpress tyrosine or related gallates. Different lineages of herbivores showed contrasting responses to the overexpression of tyrosine and its derived secondary metabolites in their host plants.

Synthesis. We propose that overexpression of some primary metabolites can serve as a chemical defence against herbivores, and are most likely to be selected for in species suffering high herbivory due to less effective secondary metabolites. Overexpression may be the first evolutionary step in the transition to the production of more derived secondary metabolites. Presumably, derived compounds would be more effective and less costly than free tyrosine as anti‐herbivore defences.
Current status of prison privatization research on American prisons and jails
Authors: Gaes Gerald G. 
Published: May 2019

Research SummaryPrivate companies manage 8.4% of the U.S. prison population and 5.4% of the jail population. On average, the costs and quality of privatized facilities seem to be about the same as publicly operated prisons, but the lack of high‐quality studies limits a strong inference. Although states with increases in prison privatization have lower public‐sector costs, this may be a result of strong cost controls, not of their level of privatization. An increase in recidivism seems to occur for people placed in private facilities. This assertion is based on the findings of several studies in which regression controls are used and on only one study in which a strong counterfactual design is applied. Finally, there is no evidence that prison privatization was responsible for the dramatic growth in incarceration that peaked in 2009.Policy ImplicationsBecause many jurisdictions will continue to use privately operated facilities, it is incumbent on them to create monitoring mechanisms to ensure high‐quality services and efficient use of resources. In this article, I suggest many ways in which research findings can contribute to a better assessment of prison and jail performance promoting accountability for both the private and the public sector.
