An inhibitor of apoptosis (SfIAP) interacts with SQUAMOSA promoter binding protein (SBP) transcription factors that exhibit pro-cell death characteristics
Authors: Kessens Ryan , Sorensen Nicholas , Kabbage Mehdi 
Published: February 2018

AbstractDespite the functional conservation of programmed cell death (PCD) across broad evolutionary distances, an understanding of the molecular machinery underpinning this fundamental program in plants remains largely elusive. This is despite its critical importance to development, homeostasis, and proper responses to stress. Progress in plant PCD has been hindered by the fact that many core regulators of animal PCD are absent in plant genomes. Remarkably, numerous studies have shown that the ectopic expression of animal anti-PCD genes in plants can suppress cell death imposed by many stresses. In this study, we capitalize on the ectopic expression of an insect inhibitor of apoptosis (SfIAP) to identify novel cell death regulators in plants. A yeast two-hybrid assay was conducted using SfIAP as bait to screen a tomato cDNA library. This screen identified several transcription factors of the SQUAMOSA promoter binding protein (SBP) family as potential SfIAP binding partners. We confirmed this interaction in vivo for our top two interactors, SlySBP8b and SlySBP12a, using coimmunoprecipitation. Interestingly, overexpression of SlySBP8b and SlySBP12a induced spontaneous cell death in Nicotiana benthamiana leaves. Overexpression of these two transcription factors also induced the accumulation of reactive oxygen species and enhanced the growth of the necrotrophic pathogen Alternaria alternata. Fluorescence microscopy confirmed the nuclear localization of both SlySBP8b and SlySBP12a, while SlySBP12a was also localized to the ER membrane. These results support a pro-death role for SlySBP8b and SlySBP12a and provide potential targets that can be utilized to improve stress tolerance in crop plants.HighlightsSBP transcription factors SlySBP8b and SlySBP12a from tomato interact with an insect inhibitor of apoptosis protein (SfIAP). Both exhibit pro-cell death characteristics while SlySBP12a activity may be regulated through ER membrane tethering.AbbreviationsPCDprogrammed cell deathIAPinhibitor of apoptosisBIRbaculovirus IAP repeatRINGreally interesting new geneFB1fumonisin B1SBPSQUAMOSA promoter binding proteinROSreactive oxygen species35Scauliflower mosaic virus 35S promoterHAhemagglutininYFPyellow fluorescent proteinDAB3,3’-DiaminobenzidineQIS-Seqquantitative interactor screen sequencingCLSMconfocal laser scanning microscopyDHEdihydroethidiumNLSnuclear localization signalTMDtransmembrane domainERendoplasmic reticulumHRhypersensitive responseMTTFmembrane-tethered transcription factor
Integrated dynamic vendor selection and order allocation problem for the time dependent and stochastic data
Authors: Aggarwal Remica , Singh Surya Prakash , Kapur P.K. 
Published: February 2018

PurposeIn this paper, vendor selection and order allocation problem is considered for a buyer dealing in multiple products to be supplied by multiple vendors. Each product has an associated lead time with stochastic demand having stochastic capacity for each vendor across entire time period. Uncertainties related to costs which are further influenced by the periodically changing incremental quantity discounts offered by various vendors. The purpose of this paper is to find an optimal trade-off of vendor selection and order allocation in the presence of uncertainties involving multiple conflicting objectives such as cost minimization, service level/quality level maximization and delivery lead time minimization concurrently.Design/methodology/approachVendor selection problem considered here has a multi-objective optimization design subject to a set of demand, capacity and quantity discount based constraints. These constraints as well as uncertainty related to lead time have been handled using chance constraint approach. The problem is titled as “integrated dynamic vendor selection problem (IDVSP).” The proposed multi-objective IDVSP is solved using both non-pre-emptive goal programming (GP) and weighted sum aggregate objective function (AOF) technique.FindingsFindings indicate goal achievement for different objectives from both non-pre-emptive GP and AOF procedure. While the goals are satisfactorily achieved as per the target values for cost and lead time, quality/service level was somewhat compromised in order to find an appropriate trade off.Originality/valueThe research work is original as it integrates dynamic as well as stochastic (uncertain) nature of supply chain simultaneously coupled with the concept of incremental quantity discounts on lot sizes.
Does board demographic diversity influence firm performance? Evidence from Indian-knowledge intensive firms
Authors: Kagzi Muneza , Guha Mahua 
Published: February 2018

PurposeIn the wake of inconsistent findings between board diversity and firm performance, the purpose of this paper is to advance the research by examining the linear and non-linear nature of the relationship between board demographic diversity (gender, age, tenure, and education) and firm performance in Indian knowledge-intensive firms (KIFs).Design/methodology/approachThis study uses a panel data set of top KIFs in India that is listed in National Stock Exchange’s Top-200 list for the period 2010-2014.FindingsResults indicate that there exists a positive linear relationship between the overall board demographic diversity index (board gender, age, tenure, and education) and firm performance. Among the effects of individual board diversity variables, the authors have found that board age diversity positively whereas education diversity negatively influences firm performance. Furthermore, gender diversity and tenure diversity do not significantly influence the firm performance.Research limitations/implicationsThis study is based on the following demographic factors: gender, age, tenure, and level of education. The authors did not include other demographic variables such as nationality and language.Practical implicationsThis research would help knowledge-intensive companies in designing their corporate boards. The results indicate that companies should have more diverse boards to enhance firm performance.Originality/valueTo the best of the authors’ knowledge, this is the first research to examine the effect of the overall board diversity index and individual board demographic diversity indices (gender, age, education, and tenure) on firm performance in the context of KIFs in India.
Sustainability assessment in manufacturing organizations
Authors: Sangwan Kuldip Singh , Bhakar Vikrant , Digalwar Abhijeet K. 
Published: February 2018

PurposeThe purpose of this paper is to develop a sustainability readiness assessment model and a sustainability assessment model for manufacturing organizations.Design/methodology/approachThe proposed models have been developed using resource-based theory along the integrated supply chain. The models are based on resources sustainability (people, money, material, energy, infrastructure, water, and air), critical factors of sustainability (product, process and policies), sustainability dimensions (environment, economic, and social), and life cycle sustainability (integrated supply chain).FindingsThe paper presents an integrated assessment system which includes: product life cycle, resources, critical factors (product, process, and policy), key performance indicators, and their interrelationship with sustainability dimensions. The three critical factors and all the important resources required by a manufacturing organization along the integrated supply chain are identified. The readiness assessment model is user friendly and effective to guide the managers to identify the weak areas of sustainability.Research limitations/implicationsThe proposed model for readiness assessment is tested and in an automotive manufacturing organization but the sustainability assessment model is conceptual and it requires validation by implementing the same in an organization to understand its effectiveness.Practical implicationsThe readiness assessment model can help the top management to decide whether the organizational orientation is correct to improve sustainability. The easy to use models can be used by the decision/policy makers and independent bodies to assess, compare and benchmark the products, processes or organizations and thus affect public policies and attitudes.Originality/valueThis study has developed, for the first time, a sustainability readiness assessment model. The resource-based theory has been applied along the integrated supply chain.
Burden or blessing in disguise: interactions in supply chain complexity
Authors: Dittfeld Hendryk , Scholten Kirstin , Van Donk Dirk Pieter 
Published: February 2018

Purpose
While systems theory explicitly considers interactions as part of a system’s complexity, supply chain complexity (SCC) is mostly conceptualized and measured as a linear summation of several aspects. The purpose of this paper is to challenge the general understanding by explicitly investigating interactions between and across different types (detail and dynamic) and levels (plant, supply chain, environment) of SCC.

Design/methodology/approach
An exploratory multiple case study methodology is adopted drawing on in-depth semi-structured interviews with respondents from eight manufacturing plants in the food processing industry.

Findings
On the one hand, it is found that different types add and increase overall SCC. On the other hand, the study also shows the opposite: interactions between detail and dynamic complexity can reduce the overall SCC experienced. Additionally, the findings highlight the specific food processing characteristics such as the variability of quality and quantity of raw materials that underlie interactions between types and levels of SCC.

Originality/value
This study adds to theory by empirically showing that interactions across and between types and levels do not automatically increase, but might also reduce SCC. As such, the findings contribute new detail to the concept of SCC: aspects of complexity do not necessarily add up linearly. Additionally, this study is one of the first to demonstrate how specific contextual aspects from the food processing industry relate to SCC.

PurposeThis paper aims to examine the relationship between psychiatry and occupational therapy in Ireland through a case study of the development of the occupational therapy department in St. Patrick’s Hospital, Dublin, from 1935 to 1969. Patronage by psychiatrists was an important factor in the professionalisation of occupational therapy internationally.Design/methodology/approachDocumentary sources and oral history interviews were analysed to conduct an instrumental case study of occupational therapy at St. Patrick’s Hospital from 1935 to 1969.FindingsThe research identified key individuals associated with the development of occupational therapy at St. Patrick’s Hospital, including psychiatrist Norman Moore, occupational therapy worker Olga Gale, occupational therapist Margaret Sinclair, and social therapist Irene Violet Grey. Occupational therapy was considered by the hospital authorities to be “an important part in the treatment of all types of psychiatric illness” (Board Meeting Minutes, 1956). It aimed to develop patient’s self-esteem and facilitate social participation. To achieve these objectives, patients engaged in activities such as dances, arts and crafts, and social activities.Originality/valueThis study has highlighted the contributions of key individuals, identified the links between occupational therapy and psychiatry, and provided an insight into the development of the profession in Ireland prior to the establishment of occupational therapy education in 1963. Occupational therapy practice at St. Patrick’s Hospital from 1935 to 1969 was congruent with the prevailing philosophy of occupational therapy internationally, which involved treatment through activities to enhance participation in society.

Authors: Malik Subhash , Tewari Puran Chand 
Published: February 2018

Purpose
The purpose of this paper is to deal with the formation of performance modeling and maintenance priorities for the water flow system (WFS) of a coal-based thermal power plant.

Design/methodology/approach
The system consists of five subsystems, i.e. condenser, condensate extraction pump, Low Pressure Heater, deaerator and boiler feed pump. The Chapman-Kolmogorov equations are generated on the basis of transition diagram and further solved recursively to obtain the performance modeling with the help of normalizing condition using Markov approach.

Findings
Availability matrices are formed with the help of different combinations of failures and repair rates of all subsystems. The performance of all subsystems is evaluated in terms of availability level achieved in availability matrices and plots of failure rates and repair rates of various subsystems. The maintenance priorities of various subsystems of WFS are decided on the basis of repair rate.

Originality/value
The adoption of both performance modeling and maintenance priorities decision by the management of thermal power plant will result in the enhancement of system availability and reduction in maintenance cost.
Efficiency and productivity performance of zakat funds in Algeria
Authors: Djaghballou Chams-Eddine , Djaghballou Mohamed , Larbani Mousa , Mohamad Azhar 
Published: February 2018

Purpose
The purpose of this study is to examine the efficiency and productivity performance of zakat funds managed by Directorates of Religious Affairs and Endowments (DRAE) in Algeria.

Design/methodology/approach
In this study, the authors employ data envelopment analysis and measure Malmquist Productivity Index for DRAE’s input and output data spanning from 2003 to 2013.

Findings
The authors find that total factor productivity has increased sharply for all zakat funds, mainly due to a technical rather than efficiency change. Further decomposition of the efficiency change into its pure technical and scale efficiency components suggests that the pure efficiency is a more important source of efficiency change than the scale efficiency component, meaning that zakat funds rely on technical aspects to gain efficiency.

Originality/value
The findings of this study are expected to contribute considerably to the existing knowledge on the operating performance of zakat funds in Algeria.
A maturity assessment model for manufacturing systems
Authors: Vivares Jorge A. , Sarache William , E. Hurtado Jorge 
Published: February 2018

PurposeAssessment of manufacturing systems provides a baseline for manufacturing strategy (MS) formulation. The purpose of this paper is to develop and propose a maturity assessment model for manufacturing systems (MAMMS). The MAMMS provides a maturity index, in order to establish manufacturing system performance on five possible levels: preinfantile, infantile, industry average, adult, and world class manufacturing.Design/methodology/approachThree main steps were taken: MAMMS design; maturity-level assessment in two companies; and MAMMS validation. Based on an action-research process, several research tools, such as surveys, expert panels, and immersion in two manufacturing companies, were used.FindingsBy integrating 79 variables into a maturity index, the maturity level for two manufacturing companies was obtained. Considering three main components (competitive priorities, manufacturing levers, and manufacturing’s strategic role), the analyzed companies showed a performance at the average industry level. According to participants, the MAMMS is a valuable tool to support decision making in MS.Practical implicationsEmpirical evidence supports the relevance of the proposed MAMMS and its practical usefulness. In particular, the maturity index identifies strengths and weaknesses in the manufacturing system, providing a baseline from which to deploy MS.Originality/valueThe literature review shows a lack of contributions regarding maturity models, particularly, the non-existence of maturity assessment models for manufacturing systems. The proposed MAMMS is a valuable tool to support decision making in MS. Also, this paper contributes to understanding the action-research paradigm, for further research in operations management.
Effects of customer experience across service types, customer types and time
Authors: Roy Subhadip 
Published: February 2018

PurposeThis study aims to investigate the relevance of customer experience quality (EXQ) across three different aspects. It compares the effect of EXQ on customer attitudes for hedonic vs utilitarian services; regular vs new customers; and new customers if they revisit or become regular customers.Design/methodology/approachThe study uses a survey design with structured questionnaires and established scales. Part of the data is collected using a longitudinal survey. Factor analysis and structural equation modeling are used as analytical techniques.FindingsMajor findings indicate a stronger effect of EXQ on consumer attitudes for a hedonic service. The effect of EXQ is found to be different on attitude variables for new and existing customers. A temporal change is observed for the new customers when they become regular.Research limitations/implicationsThe findings emphasize on the differential effect of EXQ depending on the service type and customer type. The findings also support the temporal nature of customer experience.Practical implicationsThe findings emphasize on the role of customer experience in retaining customers. The findings further imply that a service provider should consider the effect of experience both during and post-consumption for better service delivery and growth.Originality/valueThe novelty of the study lies in the comparison of the effects of experience across different service types. In addition, longitudinal exploration of changing effects of customer experience is tested for the first time as per the author’s knowledge.

Authors: Lwoga Edda Tandi , Sife Alfred Said 
Published: February 2018

Purpose
The purpose of this paper is to assess whether quality antecedents and individual characteristics can influence faculty members’ continued usage intention of electronic resources (e-resources) in selected public universities in Tanzania.

Design/methodology/approach
A total of 204 faculty members participated in the study from three public universities in Tanzania. The study used structural equation modelling, ANOVA and t-tests to perform analyses.

Findings
Better educated and middle-aged faculty members with a wide experience of using e-resources are more likely to continue using e-resources. Information quality had positive relationship with continued usage intention of e-resources while service quality had indirect impact to continued usage intention through information quality and system quality.

Originality/value
Based on the DeLone and McLean information systems success model, this study integrates quality factors (information, service and system quality) and individual characteristics as antecedents to the continued usage intention of e-resources. The study comprehensively documents empirical findings on impacts of quality factors and individual characteristics on e-resources in a developing country. The study reveals results that are useful for enhancing usage of e-resources by faculty in other institutions with similar conditions.

Published: February 2018

PurposeDiscovering the research topics and trends from a large quantity of library electronic references is essential for scientific research. Current research of this kind mainly depends on human justification. The purpose of this paper is to demonstrate how to identify research topics and evolution in trends from library electronic references efficiently and effectively by employing automatic text analysis algorithms.Design/methodology/approachThe authors used the latent Dirichlet allocation (LDA), a probabilistic generative topic model to extract the latent topic from the large quantity of research abstracts. Then, the authors conducted a regression analysis on the document-topic distributions generated by LDA to identify hot and cold topics.FindingsFirst, this paper discovers 32 significant research topics from the abstracts of 3,737 articles published in the six top accounting journals during the period of 1992-2014. Second, based on the document-topic distributions generated by LDA, the authors identified seven hot topics and six cold topics from the 32 topics.Originality/valueThe topics discovered by LDA are highly consistent with the topics identified by human experts, indicating the validity and effectiveness of the methodology. Therefore, this paper provides novel knowledge to the accounting literature and demonstrates a methodology and process for topic discovery with lower cost and higher efficiency than the current methods.
