Abstract
Purpose
The purpose of this research is to examine the relationship between coaching leadership and employees' taking charge while incorporating the mediating role of work meaningfulness and the moderating role of challenge-hindrance stressor.
Design/methodology/approach
A total of 355 pairs of effective samples were collected through a two-stage supervisor-subordinate paired survey. Four hypotheses were tested using hierarchal regression analysis and bootstrapping method.
Findings
The findings show that coaching leadership is positively related to taking charge, and work meaningfulness positively mediates the coaching leadership-taking charge relationship; high challenge stressors and high hindrance stressors weaken the positive effect of coaching leadership on work meaningfulness respectively; challenge stressors and hindrance stressors further moderate the indirect relationship of coaching leadership and taking charge through work meaningfulness.
Originality/value
This study provides a new perspective for organizations to activate employees' taking charge, thereby enriching the antecedents of taking charge. By incorporating challenge-hindrance stressor framework, this study also provides answers to when coaching leadership will be less effective.

Abstract
Purpose
The purpose of this paper is to explore the relationship between challenge-hindrance stressors and employees’ career initiative while incorporating the mediating role of positive affect and the moderating role of job autonomy.
Design/methodology/approach
Five proposed hypotheses were tested using path analysis with two waves of data collected from 136 part-time MBA students.
Findings
The findings show that challenge stressors indirectly facilitate career initiative, whereas hindrance stressors indirectly inhibit career initiative, both with positive affect as mediators. Job autonomy enhances the direct relationship between positive affect and career initiative, as well as the indirect relationships among challenge/hindrance stressors, positive affect and career initiative.
Originality/value
The study brings a new perspective to understanding why an employee conducts career initiative, thereby widening the scope of the antecedents of career initiative. The study discloses positive affect as the mediator that transmits the opposite effects from challenge-hindrance stressors to career initiative. It also identifies job autonomy as an important boundary condition for positive affect to exert its influence on career initiative, as well as challenge-hindrance stressors that influence career initiative via positive affect.

Abstract
Purpose: Drawing on research in crime and media studies, this research examines media images and stereotypes of criminals within the popular television crime drama series Bones. Methodology/approach: All 24 episodes of Season 9 were examined. Through a content analysis offender gender, race, age, offense type, and motive were examined. Findings: This research revealed that most of the images do not reflect the reality of crime and criminals. Gendered and racialized images were revealed. While male minorities’ victimization was more accurately portrayed, White females were cast in the stereotype as the emotional offender and minority females’ criminality was portrayed as similar to male criminals.

Abstract
Over the past few years, the electronic media, as represented by the internet version of print media and independent blogs of journalists, has become a major player in the coverage of incidents related to violence against women. While this has brought forward issues of violence and specifically rape prominently into the public sphere, the media portrayal of women has often been as victims or victims who are somehow responsible for the violence against them. Such portrayal has been repeatedly challenged by feminists. Using data from 572 national and international English media reports for a six-month period (from December 2012 to April 2013) the coverage of the protests about the 2012 case of gang rape and eventual death of Jyoti Singh Pandey in India’s capital city, New Delhi, is examined in this chapter. Drawing from past research, three main frames are discerned in the portrayal of women in the reports: mainstreaming gender, endangered woman, and the ungendered woman. Media portrayals of these three frames by three broadly categorized actors most prominently covered by the media reports are analyzed: activists, state representatives or political actors, and ordinary citizens. The findings suggest that while some reports allude to women’s agency and rights particularly when they cover feminist activists, women’s agency is marginalized in the debates around safety and protection for women when other actors (such as state representatives or political actors, and ordinary citizens) are considered. Indian women’s rights have been reduced to passive messages negating the broader politics of the contemporary women’s movement.

Abstract
Purpose: This study explored technology-mediated abuse (TMA) by looking at the influence of topic exposure via education (in/formal), media (non/fictional), and personal experiences (self/close others) in shaping public knowledge, understandings, and perceptions of TMA.
Methodology: Community-sampled respondents (N = 551; n = 235 men, 263 women; aged 18–81 years, M = 27.42, SD = 12.31) reported their TMA awareness and topic exposure (n = 110; 20% of the total sample indicated prior exposure).
Findings: Results indicated TMA knowledge, understanding, and perceptions varied by prior sources of topic exposure. This suggests that TMA is a crime varying in public awareness and perceived repercussions.
Research limitations: Open-ended responses, although ideal for exploratory studies such as this one, limit the scope and power of quantitative analyses. Future work should test the current study’s conclusions in a generalizable, random sample via closed-item surveys.
Originality/value: Present findings elucidate which societal forces and education types are best suited for helping people understand TMA in all its complexity. Such understanding allows for practical considerations of the comparative in/effectiveness of formal curriculum and media in shaping cognitions regarding TMA victimization.

Abstract
Purpose
The purpose of this paper is to introduce an interval finite element method (IFEM) to simulate the temperature field of mass concrete under multiple influence uncertainties e.g. environmental temperature, material properties, pouring construction and pipe cooling.
Design/methodology/approach
Uncertainties of the significant factors such as the ambient temperature, the adiabatic temperature rise, the placing temperature and the pipe cooling are comprehensively studied and represented as the interval numbers. Then, an IFEM equation is derived and a method for obtaining interval results based on monotonicity is also presented. To verify the proposed method, a non-adiabatic temperature rise test was carried out and subsequently simulated with the method. An excellent agreement is achieved between the simulation results and the monitoring data.
Findings
An IFEM method is proposed and a non-adiabatic temperature rise test is simulated to verify the method. The interval results are discussed and compared with monitoring data. The proposed method is found to be feasible and effective.
Originality/value
Compared with the traditional finite element methods, the proposed method taking the uncertainty of various factors into account and it will be helpful for engineers to gain a better understanding of the real condition.

Abstract
Purpose
In the last decade, cloud manufacturing (CMfg) has attracted considerable attention from academia and industry worldwide. It is widely accepted that the design and analysis of cloud manufacturing architecture (CMfg-A) are the basis for developing and applying CMfg systems. However, in existing studies, analysis of the status, development process and internal characteristics of CMfg-A is lacking, hindering an understanding of the research hotspots and development trends of CMfg-A. Meanwhile, effective guidance is lacking on the construction of superior CMfg-As. The purpose of this paper is to review the relevant research on CMfg-A via identification of the main layers, elements, relationships, structure and functions of CMfg-A to provide valuable information to scholars and practitioners for further research on key CMfg-A technologies and the construction of CMfg systems with superior performance.
Design/methodology/approach
This study systematically reviews the relevant research on CMfg-A across transformation process to internal characteristics by integrating quantitative and qualitative methods. First, the split and reorganization method is used to recognize the main layers of CMfg-A. Then, the transformation process of six main layers is analysed through retrospective analysis, and the similarities and differences in CMfg-A are obtained. Subsequently, based on systematic theory, the elements, relationships, structure and functions of CMfg-A are inductively studied. A 3D printing architecture design case is conducted to discuss the weakness of the previous architecture and demonstrate how to improve it. Finally, the primary current trends and future opportunities are presented.
Findings
By analyzing the transformation process of CMfg-A, this study finds that CMfg-A resources are developing from tangible resources into intangible resources and intelligent resources. CMfg-A technology is developing from traditional cloud computing-based technology towards advanced manufacturing technology, and CMfg-A application scope is gradually expanding from traditional manufacturing industry to emerging manufacturing industry. In addition, by analyzing the elements, relationships, structure and functions of CMfg-A, this study finds that CMfg-A is undergoing a new generation of transformation, with trends of integrated development, intelligent development, innovative development and green development. Case study shows that the analysis of the development trend and internal characteristics of the architecture facilitates the design of a more effective architecture.
Research limitations/implications
This paper predominantly focuses on journal articles and some key conference papers published in English and Chinese. The reason for considering Chinese articles is that CMfg was proposed by the Chinese and a lot of Chinese CMfg-A articles have been published in recent years. CMfg is suitable for the development of China’s manufacturing industry because of China’s intelligent manufacturing environment. It is believed that this research has reached a reliable comprehensiveness that can help scholars and practitioners establish new research directions and evaluate their work in CMfg-A.
Originality/value
Prior studies ignore the identification and analysis of development process and internal characteristics for the current development of CMfg-A, including the main layers identification of different CMfg-As and the transformation process analysis of these main layers, and in-depth analysis of the inner essence of CMfg-A (such as its elements, relationships, structure and functions). This study addresses these limitations and provides a comprehensive literature review.

Abstract
This study examines the relationship between fashion leadership, clothing deprivation and satisfaction of Hong Kong young consumers. A survey was carried out with 309 university students and 228 working young people in Hong Kong. Factor analysis with varimax rotation was used to group various attributes into different factors related to clothing deprivation and satisfaction. Hirschman and Adcock's (1978) measure was adopted to classify subjects into various fashion groups. ANOVA followed by Scheffe's procedure was applied to detect differences in clothing deprivation and satisfaction between different fashion groups. The implications of the findings to fashion retailers are discussed.
