Abstract

Purpose

Longitudinal facial cracks (LFC) are one of the major defects occurring in the continuous-casting stage of thin slab caster using funnel molds. Longitudinal cracks occur mainly owing to non-uniform cooling, varying thermal conductivity along mold length and use of high superheat during casting, improper casting powder characteristics. These defects are difficult to capture and are visible only in the final stages of a process or even at the customer end. Besides, there is a seasonality associated with this defect where defect intensity increases during the winter season. To address the issue, a model-based on data analytics is developed.

Design/methodology/approach

Around six-month data of steel manufacturing process is taken and around 60 data collection point is analyzed. The model uses different classification machine learning algorithms such as logistic regression, decision tree, ensemble methods of a decision tree, support vector machine and Naïve Bays (for different cut off level) to investigate data.

Findings

Proposed research framework shows that most of models give good results between cut off level 0.6–0.8 and random forest, gradient boosting for decision trees and support vector machine model performs better compared to other model.

Practical implications

Based on predictions of model steel manufacturing companies can identify the optimal operating range where this defect can be reduced.

Originality/value

An analytical approach to identify LFC defects provides objective models for reduction of LFC defects. By reducing LFC defects, quality of steel can be improved.

Abstract

Purpose

The purpose of this paper is to draw on scientific models in conceptualising the evolutionary bases of contemporary behaviours, and make cross‐species comparisons, to account for male managerial activities in situ in health organizations.

Design/methodology/approach

In the animal world, males of many species display in order to induce females to mate. Such lekking behaviour involves inter alia, strutting, puffing out, catching attention via the use of ornamental physical characteristics, exhibiting gaudily‐coloured body parts, singing or splashing, and other courting and wooing strategies. The paper applies these behavioural repertoires as an explanatory device for male‐dominant organizational lekking in a set of contemporary settings. It draws on six studies of managerial talk, appearance and behaviour in order to do so.

Findings

Within the organizational lek male managers display mainly by power dressing, positioning, and exercising power and influence via verbal and behavioural means. Social and religious mores prohibit overt sexual coupling in organizations but lekking for other rewards is nevertheless pursued by male managers. The paper explores this managerial patterning, compares it to the lekking behaviour of other species, and discusses points of comparison and departure. It shows how male managers display within various sub‐habitats, and discusses the central issues of appearance, tasks and work assignment, physical interaction structure, and talk and physiognomy.

Practical implications

Understanding what makes people tick via deep explanations than are customarily rendered is a vital contribution of scholarship to the practical world of management.

Originality/value

The evolutionary bases of contemporary behaviours, and cross‐species accounts, may prove useful paradigms for other theorists and empiricists in organizational studies, and could encourage the development of a new field that might be labeled evolutionary organizational behaviour.

Abstract

Lesbian, gay and bisexual (LGB) employees constitute one of the largest, but least studied, minority groups in the workforce. This article examines what we know, and what we need to know, about the career and workplace experiences of this understudied population. The construct of sexual identity is defined, followed by a review of the research on sexual orientation in the workplace. Then an analysis of the differences between LGB employees and other stigmatized groups is presented. Three unique challenges facing LGB employees are identified, and conceptual models are developed that explain underlying processes. Finally, career theories are critically analyzed, and an identity-based longitudinal theory of LGB careers is presented.

Abstract

Three events of significance to this country took place in 1899 – the British Food Journal was launched, Australia retained the Ashes, and the Boer War hostilities commenced. If challenged on the order of their importance, cricketers and Empire‐builders may be excused their preference. However, looking at it purely from the standpoint of pro bono publico, the dispassionate observer must surely opt for the birth of a certain publication as being ultimately the most beneficial of the three.

Abstract

Purpose

The emotional labor of headteachers and teachers is complex. The purpose of this paper is to explore the relevance of the use of the Mayer-Salovey-Caruso Emotional Intelligence test (MSCEIT) (Mayer, Caruso & Salovey, 2000) when assessing the emotional intelligence of headteachers as part of an investigation which aimed to reveal the ways in which female secondary school leaders were emotionally intelligent and whether it was possible to test for emotional intelligence.

Design/methodology/approach

Seven female headteachers’ MSCEIT reports are investigated. Semi-structured interviews were held pre- and post-test to explore the headteachers’ emotional labor. In addition, teachers serving under the headteachers were interviewed.

Findings

The accuracy of the MSCEIT is questioned, rather than taking the results at face value, attention is given to its content, language and cultural differences. The MSCEIT originates from the USA and is used globally. The findings of this investigation suggest it is possible the MSCEIT represents a deficit model due to the test takers’ interpretation of nuanced language. The findings show a disparity in relation to MSCEIT scores and self-reported emotional responses.

Research limitations/implications

Although the sample size is small and therefore cannot claim generalization from the findings, the use of emotional intelligence tests should be used with caution. Emotional responses are best understood through life experience as the headteachers attach retrospective meaning to their leadership actions.

Originality/value

Headteachers’ work is multifaceted because emotion is integral to the processes of teaching and learning. The emotional labor of headteachers and teachers impacts and has relevance to their roles as educational landscapes continue to shift.
