Abstract
Purpose
The purpose of this paper is to present a model that can be used to simulate the photopolymerization process in micro‐stereolithography (SL) in order to predict the shape of the cured parts. SL is an additive manufacturing process in which liquid photopolymer resin is cross‐linked and converted to solid with a UV laser light source. Traditional models of SL processes do not consider the complex chemical reactions and species transport occurring during photopolymerization and, hence, are incapable of accurately predicting resin curing behavior. The model presented in this paper attempts to bridge this knowledge gap.
Design/methodology/approach
The chemical reactions involved in the photopolymerization of acrylate‐based monomers were modeled as ordinary differential equations (ODE). This model incorporated the effect of oxygen inhibition and diffusion on the polymerization reaction. The model was simulated in COMSOL and verified with experiments conducted on a mask‐based micro‐SL system. Parametric studies were conducted to investigate the possibilities to improve the accuracy of the model for predicting the edge curvature.
Findings
The proposed model predicts well the effect of oxygen inhibition and diffusion on photopolymerization, and the model accurately predicts the cured part height when compared to experiments conducted on a mask‐based SL system. The simulated results also show the characteristic edge curvature as seen in experiments.
Research limitations/implications
A triacrylate monomer was used in the experiments conducted, so results may be limited to acrylate monomers. Shrinkage was not considered when comparing cured part shapes to those predicted using COMSOL.
Originality/value
This paper presents a unique and a pioneering approach towards modeling of the photopolymerization reaction in micro‐SL process. This research furthers the development of patent pending film micro‐SL process which can be used for fabrication of custom micro‐optical components.

Abstract
Purpose
The purpose of this paper is to identify the targets, strategies, and topics of deception employed in the workplace among part‐time service workers.
Design/methodology/approach
A taxonomy of deception strategies is used to content analyze 259 narrative accounts of part‐time student employees over two work shifts using Cohen's kappa to measure interrater reliability. Chi‐square analysis is used to determine significant differences between deception strategies and deception targets.
Findings
Employees overwhelmingly concealed information and lied primarily to supervisors and customers. Employees deceived in order to cover or protect emotions, evade work, cover mistakes or policy violations, and mislead customers in order to increase sales, commission, or gratuities.
Research limitations/implications
Determining the most salient strategies employed becomes clearer if the deception account describes or reveals the employee's motivation to deceive. Future research should consider motivation of the deceiver and might compare the deception strategies of part‐time and full‐time employees of varying levels of skill, organizational commitment, and role conflict.
Practical implications
This study provides rich examples of the ethically compromising situations in which young workers find themselves, discusses the impact of workplace structures on deception and the importance of socializing young workers on honest organizational practices.
Originality/value
As young workers enter the workforce they are confronted with opportunities to deceive and they do so for a wide variety of reasons. Little work has been done within the organizational context investigating the most common deception strategies employed or the contextual factors influencing the use of deception among full‐time employees much less young, part‐time employees.

Abstract
Purpose
This paper aims to examine the direct and indirect effects of the use of electronic markets (e‐markets), access to online data and trading partner collaboration on operational performance.
Design/methodology/approach
This study involved survey data from 233 Australian firms. Data were provided by members of the Chartered Institute of Purchasing and Supply Australia, who reflected upon relevant practices and performances of their firms. Structural equation modeling was used to analyze the data.
Findings
The results show that whilst all three direct effects are non‐significant, when the indirect effects are taken into account, the total effects are significant in strength. This suggests that use of e‐markets, access to online data and collaboration with trading partners, when taken in isolation, are not as effective as could be expected. However, when these factors are implemented together, their value and impact becomes significant.
Research limitations/implications
The study is limited to Australian firms.
Practical implications
The results highlight that investments in information and communication technology must be deployed in an holistic manner, for example, by combining use of web‐based applications and market mechanisms with effective data sharing and collaboration, if they are to produce significant improvements in operations.
Originality/value
While e‐markets may have been viewed as a mechanism for reducing the costs of inputs and/or as a new demand channel, this study establishes that more value can be extracted when this technology is viewed and exploited in a more strategic manner. E‐markets should be used in concert with access to data and collaboration with trading partners who are able to exploit the opportunities for mutual benefit.

Abstract
Purpose
The purpose of this paper is to replicate and extend earlier work on product gender perceptions.
Design/methodology/approach
The methodology tested six hypotheses, using nearly 500 respondents. The hypotheses were investigated using a survey approach with validated scales. Likert‐type data were analyzed using appropriate statistical measures.
Findings
Analysis of the data demonstrated that product gendering is still prevalent. In addition, males were more likely than females to purchase gender‐congruent products; that individuals with a greater desire for product‐self‐congruence used products as a form of self‐concept; that individuals reared in non‐traditional households were less focused on gender congruence; that less traditional individuals were less focused on gender congruence; and that those who sought gender congruence were more likely to seek gender cues in the marketing mix.
Research limitations/implications
The product selection was based on a previous study and the sample was non‐random. Both of these decisions could be questioned.
Practical implications
These research results will allow one to understand whether social change during the past decade has altered product gender perceptions and to explore the degree to which consumers seek congruence between their own gender orientations and perceived product gender. This knowledge could be very important to consumer goods marketers making product design and promotional decisions.
Originality/value
The paper examines gender congruence in a maturing Generation Y, a generation second in size only to the Baby Boomers and one of significant market importance. It also provides the first substantive new data on this subject in over a decade.

Abstract
Purpose
The aim of this paper is explore consequences of ambivalence and ambiguity on self‐concept, decision‐making, and quality of interrelationships between management and employees in one for‐profit organisation.
Design/methodology/approach
Data were re‐read to reveal that organisational members were constantly engaged in the process of changing their perceptions of “who” and “what” were “good” and “bad” in reaction to environmental change impacts.
Findings
The paper finds that philosophically, “splitting” is an age‐old form of decision‐making; psychodynamically, “splitting” is not necessarily a signal to a pathology but instead is merely an initiator of ambiguity and ambivalence that leverages change; from a change management perspective, “splitting” can reinforce polarisation that can impede the desire to engage in continual change; and predictions and perceptions of change consequences underscore both the quality and quantity of “splitting” in regard to polarisation. “Splitting” is an integral defense and offense change mechanism that occurs in all decision‐making, so practical implications are that its affects on self and other concepts need to be understood. To establish equalising and non‐polarised interrelationships between “employer” and “worker” and to negate the line between management and employee, exercises in recognition of mutual causation such as servant leadership practises can be introduced.
Originality/value
Unparalleled synthesis of seemingly divergent theoretical and practical studies, this paper is a valuable ontological and epistemological tool for ongoing investigation into complexity theory, including self and other organisation.

This paper seeks to propose a methodology to measure the extent of collaboration between apparel retailers and manufacturers in the apparel retail industry in India.
Abstract
Purpose
This paper seeks to propose a methodology to measure the extent of collaboration between apparel retailers and manufacturers in the apparel retail industry in India.
Design/methodology/approach
The proposed model for measuring collaboration considers variables like top management commitment, information sharing, trust among supply chain partners, long‐term relationships and risk and reward sharing. Level of collaboration is measured using graph theory.
Findings
The survey results confirmed the validity of the proposed collaboration index for measuring collaboration. The findings also show that the collaboration index is positively associated with operational performance.
Research limitations/implications
Future research could consider larger sample sizes and cover other industrial sectors.
Practical implications
Supply chain partners will be able to measure the extent of their collaboration and seek improvement in their performance. This approach helps to compare organizations in terms of their collaboration capability.
Originality/value
This paper contributes to the literature by introducing an index for measuring the extent of supply chain collaboration. This measure can be used by any participant (member) in a supply chain to determine the level of collaboration and seek improvement.

Abstract
Purpose
The importance and criticality of sustainable development goals is witnessed by 195 member countries. For its full-fledged adoption and implementation, it needs to be understood by masses and political leaders are critical agents those engage diverse communities through social media such as twitter. Therefore, in this study focuses on how political leaders can influence the sustainable development goals through Twitter.
Design/methodology/approach
This study examines the social media conversations of political leaders on Twitter. Social media analytics methods such as sentiment mining, topic modelling and content analysis-based methods have been used.
Findings
The findings indicate that most political leaders are primarily discussing the sustainable development goals (SDGs) “partnership for goals” and “peace, justice and strong institutions”. Many other goals such as “clean water and sanitation”, “life below water”, “zero hunger”, “no poverty” and “educational quality” are not being focused on.
Research limitations/implications
This study offers implications in terms of collective decision making and the role of policy makers towards the goals of promoting SDGs. The authors highlight how political leaders need to involve key stakeholders in this journey.
Originality/value
This study scores and provides a cohort-specific prioritization of the leadership within these countries with regard to SDGs, which could be beneficial to the society.

Abstract
Purpose
Seeks to test the relative importance of various drivers of information‐technology‐related performance, and compare these drivers in the context of using established and emerging technologies. Established technologies include those generally promoted as the European Article Numbering (EAN) system (electronic data interchange (EDI), barcoding, etc.), while the emerging ones are based on the use of the internet.
Design/methodology/approach
A survey was designed based on previous research and a series of case studies conducted within the membership of EAN Australia. The method of analysis employed was structural equation modelling based on data collected from 553 members of the EAN organisation in Australia.
Findings
Use of technology enabling business‐to‐business (B2B) e‐commerce was found to provide a potential source of performance improvement, but such improvement is shown to be more a function of the process by which strategy is formulated, and organisational capability, than of the technologies per se. The adoption and use of emerging technologies (such as the internet) are not subject to the same restrictions and impediments traditionally associated with established technologies. Therefore, organisations will find emerging internet‐based technologies easier to implement and to use, but this will not necessarily mean that they will improve performance as a result. Performance will still be determined by effective strategy formulation, a clear understanding and knowledge of the technologies, appropriate application, and prudent change management.
Research limitations/implications
This research has been conducted in Australia, and restricted to the membership of the EAN organisation. This membership is largely representative of the fast‐moving consumer goods (FMCG) industry. Whether such results would be consistent in other countries and industries would need to be verified through further research.
Originality/value
Develops and tests an integrated model linking strategy formulation, knowledge, capability, use of technology and performance. Provides valuable insight into why and how technology implementations can be configured for success.

Abstract
The American Institute of Certified Public Accountants and the Accounting Education Change Commission have mandated the adoption of 150 semester hours for accounting students and as a prerequisite for taking the CPA examination. More than 40 states have already adopted the 150‐hour requirement. Proponents of the change have argued that accounting education has to change from a knowledge‐based education to a process‐oriented programme and develop a process of inquiry and a desire for life‐long learning in the students. They hope to effect changes to result in improved intellectual, communication, and interpersonal skills, and a better understanding of the broad picture in a business. It is argued here that although the mandate may have been well‐intentioned but knowingly or unknowingly the authors have chosen to ignore the most essential component, i.e. what does it take to teach the students for success in the accounting profession? It is argued that the missing link is primarily trained and versatile teachers, followed with the lacking prerequisites for the students and their parents. Furthermore, no consideration has been given to the additional cost involved for the students and their parents and the question of commensurate job opportunities for those involved.
