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

In this chapter, the authors examine the use of deceit to drive routine emergence. The authors do so by tracing the relationship among deceit, roles, and routine dynamics in the context of Romeo pimps and the women they lure into sex trafficking. Previous research has focused on routine participants openly negotiating their roles and expected interactions during the (re) creation of routines. In contrast, this study shows how Romeo pimps use deceit to control the co-constitution of roles and increasingly coercive actions of the “Romeo pimp routine” – a process of premeditated routine emergence designed to entrap the women. The authors contribute to the literature on routine dynamics by emphasizing the unexplored influence of deceit on the interplay between roles and routines. Bringing deception to center stage in routine dynamics highlights the importance of linking actors and actions to motivations that exist behind the veil of transparently observable behavior.

Abstract

Purpose: This chapter examines how healthcare technologies (electronic medical records, personal cell phones, and pagers) help manage patient care work to accelerate processes of communication and blur boundaries between work time and non-work time, thereby revealing dynamics of power as indicated through temporal capital, or the amount of time under an individual’s control.

Method: The data were collected from 35 in-depth semistructured interviews of health practitioners, which included 26 physicians, 7 nurses, and 2 administrators.

Findings: Communication technologies fulfill promises of temporal autonomy and efficiency, but not without cost, particularly as it intersects with organizational/institutional power structures and non-work-related social factors such as pre-existing technological literacy and proficiency. The blurring of work and non-work time gives practitioners perceived higher quality of life while also increasing temporal flexibility and autonomy. The higher up one is in the relevant hierarchy, the more control one has over one’s own time, resulting in higher levels of temporal capital. The power hierarchies serve to complicate the potential recuperation of temporal capital by communication technologies.

Implications: This study uses a critical cultural perspective that takes into consideration structures of institutional power hierarches impact temporal organization through the use of communication technologies by health practitioners. Practitioner-facing research is particularly crucial given the high rates of burnout within the profession and concerns around the well-being of health practitioners, and autonomy and control over one’s time is a factor in work and life satisfaction.

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

Although there is great potential for diversity, library and information science (LIS) is a relatively homogenous profession. Increasing the presence of librarians of color may help to improve diversity within LIS. However, recruiting ethnic minorities into LIS has proven to be difficult despite various initiative including scholarships, fellowships, and locally focused programs. The central questions explored in this research can be divided into two parts: (1) Why do ethnic minorities choose librarianship as a profession? (2) What would motivate members of minority groups to join a profession in which they cannot see themselves?

The research was conducted through semi-structured, qualitative interviews of 32 ethnic minority students from one of four ethnic minority groups (African American, Asian American, Hispanic/Latino, and Native American) currently enrolled in an LIS graduate program. Eleven themes emerged from the data: libraries, librarians, library work experience, LIS graduate program, career plans and goals, education and family, support, mentors, ethnicity and community, acculturation, and views of diversity.

The findings seem to support many assumptions regarding expectations and career goals. The findings related to libraries, librarians, mentors, and support illustrate that many recruitment initiatives are starting in the right place. However, the most noteworthy findings were those that centered on identity, acculturation, and diversity because they dealt with issues that are not often considered or discussed by many in the profession outside of ethnic minority organizations.

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.
