Abstract
In this chapter, we review empirical research evidence on the relationship between stressors and catecholamines (i.e., adrenaline and noradrenaline) and cortisol. With respect to acute stressors, both laboratory and field research have shown that the exposure to stressors leads to an increase in catecholamine and cortisol levels. With respect to more chronic stressors, research evidence is less consistent. Chronic mental workload was found to be related to elevated adrenaline levels. With respect to cortisol responses the interaction between workload and other variables seems to play a role. Empirical studies suggest that chronic stressors affect the responsivity to acute stressors. Research showed that after the exposure to stressors catecholamine and cortisol recovery is delayed.

Abstract
The idea that a significant portion of what consumers do, feel, and think is driven by automatic (or “implicit”) cognitive processes has sparked a wave of interest in the development of assessment tools that (attempt to) capture cognitive processes under automaticity conditions (also known as “implicit measures”). However, as more and more implicit measures are developed, it is becoming increasingly difficult for consumer scientists and marketing professionals to select the most appropriate tool for a specific research question. We therefore present a systematic overview of the criteria that can be used to evaluate and compare different implicit measures, including their structural characteristics, the extent to which (and the way in which) they qualify as “implicit,” as well as more practical considerations such as ease of implementation and the user experience of the respondents. As an example, we apply these criteria to four implicit measures that are (or have the potential to become) popular in marketing research (i.e., the implicit association test, the evaluative priming task, the affect misattribution procedure, and the propositional evaluation paradigm).

Abstract
Purpose
Focusing on 420 women employed within the woman-dominated health care sector, the purpose of this paper is to investigate how any variation in their total workload (TWL) in terms of paid and unpaid work relate to various subjective health complaints (SHC) (n=420) and the neuroendocrine stress marker cortisol (n=68).
Design/methodology/approach
The authors explored how any variation in their TWL in terms of paid and unpaid work related cross-sectionally to SHC (n=420), and the neuroendocrine stress marker cortisol (n=68).
Findings
Hierarchical regression analyses showed that stress of unpaid work was most strongly related to diurnal variations in cortisol. Both stress of paid and unpaid work as well as TWL stress, but not hours spent on TWL, were related to SHC.
Practical implications
Taken together, objective measures of hours spent on various TWL domains were unrelated to outcome measures while perceptions of having too much TWL and TWL stress were linked to both cortisol and SHC, i.e. how individuals perceive a situation seem to be more important for health than the actual situation, which has implications for research and efforts to reduce individual TWL.
Originality/value
This study is unique in showing that unpaid work and perceptions having too much TWL relate to stress markers in women working in the public health care sector.

Abstract
Purpose
The purpose of this paper is to develop and validate a measure of job insecurity climate by: first, testing whether job insecurity climate and individual job insecurity are two separate constructs; and second, investigating the relative importance of individual job insecurity and job insecurity climate in predicting work-related and health-related outcomes.
Design/methodology/approach
Data were collected by questionnaires in a simple stratified random sample of 1,380 white-collar workers in Sweden. The response rate was 56 percent.
Findings
Confirmatory factor analyses showed that job insecurity climate was distinct from individual job insecurity. Four separate ridge regression analyses showed that qualitative job insecurity climate was a significant predictor of demands, work-family conflict, psychological distress, and poor self-rated health and that quantitative job insecurity climate predicted demands and work-family conflict.
Research limitations/implications
The study is based on self-reports, which may involve common method bias. The cross-sectional study design limits the possibility to make causal inferences regarding the relationship between job insecurity climate and outcomes.
Practical implications
Future studies may consider measuring job insecurity climate in line with a referent-shift model. Work environment surveys in organizations that include measures of individual job insecurity and job insecurity climate can provide practitioners with a fuller picture of the psychosocial work environment.
Originality/value
The present study adds to previous research by introducing a new approach to measuring and conceptualizing job insecurity climate.

Abstract
This paper is an empirical analysis of first-price sealed-bid procurement auctions in Sweden, with and without combinatorial bidding. The data comprises procurement auctions of identical contracts (road resurfacing) with identical bidders conducted under the same time period (2009-2011) in two different regions in Sweden. Given the comparison of the suppliersʼ offered price per tons of asphalt, we cannot reject the hypothesis of identical distribution of standalone bids generated in both types of auction. The distribution of package bids within the combinatorial format is significantly lower than the distribution of standalone bids within the non-combinatorial format, suggesting substantial cost reduction of allowing package bidding. Also, within the combinatorial format, our analysis of data indicates higher costs when packages are predetermined by the purchaser rather than chosen freely by the suppliers.

Abstract
Purpose
Research internships are integral components of undergraduate programs that nurture students' skill sets. However, the current trend of these internships adopting a direct apprenticeship model, often termed “cookbook” laboratory sessions, falls short of cultivating 21st-century skills. Therefore, this study proposes an innovative Outcomes-directed Research Internship Model (ODRIM) designed to enhance research competencies.
Design/methodology/approach
This study introduces a pioneering research internship model by integrating the course-based undergraduate research experience (CURE) framework with principles rooted in outcomes-based education (OBE). To evaluate its effectiveness and compare it with traditional research internship models (TRIMs), a two-group pretest-posttest design was utilized. Statistical analysis was performed on data collected from 66 participants to assess their research competencies.
Findings
The results revealed a significant positive difference in utilizing the tailored innovative ODRIM track (pre-mean = 17.525, post-mean = 19.875; p = 0.009) compared to the TRIM track (pre-mean = 19.769, post-mean = 19.615; p = 1.000) in enhancing overall student research competency. Specifically, this innovative internship model notably enhanced students’ abilities in conducting research, showcasing technical skills, collaborating within teams, and disseminating research outcomes, encompassing the composition of research articles and reports.
Originality/value
This tailored approach to the “Research Internship” encourages a harmonious blend of hands-on, inquiry-based learning and clear, measurable learning goals. It not only cultivates an immersive and thorough research experience to improve students’ research competencies, but also guarantees a concentrated alignment with predetermined research learning objectives.

Abstract
IN accurate performance calculations it is usual to calculate the two curves for the horse‐power required and available (against the path velocity), especially in the case where the individual engine and airscrew characteristics are to be considered. With the principles applied in this article it is recommended to use instead the rising and sinking speeds respectively. Here only the sinking‐speed part of the problem is to be studied. It is well known that the calculation of the curves for the horse‐power required or the sinking speed involves considerable labour, especially when the calculations must be repeated for different heights and for different alternatives or assumptions according to the design and aerodynamic qualities of the aeroplane.

Abstract
The preponderance of studies that rely on self-report for both independent (e.g. stressors) and dependent (e.g. well-being) variables is often deplored, as it creates problems of common method variance, which may lead to inflated, or even spurious, correlations and predictions. It is sometimes suggested that alternative measures should yield more “objective” information on the phenomena under investigation. We discuss this issue with regard to: (a) observational measures of working conditions; (b) physiological measures of strain; and (c) event-based “self-observation” on a micro-level. We argue that these methods are not necessarily “objective.” Like self-report, they are influenced by a plethora of factors; and measurement artifacts can easily be produced. All this can make their interpretation quite difficult, and the conclusion that lack of convergence with self-report automatically invalidates self-report is not necessarily warranted. Especially with regard to physiological measures, one has to keep in mind that they refer to a different response level that follows its own laws and is only loosely coupled with psychological responses. Therefore, replacement is not a promising way to get more reliable estimates of stressor-strain relationships. We argue instead that each method contains both substantive and error variance, and that a combination of various methods seems more auspicious. After discussing advantages and pitfalls of observational, physiological, and self-observational measures, respectively, we report empirical examples from our own research on each of these methods, which are meant to illustrate both the advantages and the problems associated with them. They strengthen the overall conclusion that there is no “substitute” for self-report (which often is necessary to be able to interpret data from other methods, most notably physiological ones). They also illustrate that collecting such data is quite cumbersome, and that a number of conditions have to be carefully considered before using them, and we report some problems we encountered in this research. Altogether, we conclude that self-report measures, if carefully constructed, are better than their reputation, but that the optimal way is to complement them with other measures.

Abstract
Purpose
The purpose of this paper is to identify the determinants of perceived work-related stress among public sector managers.
Design/methodology/approach
A general questionnaire-based survey of managers at all managerial levels in Danish organizations concerning the content of their job and the way it is practiced (n=1,500, response rate 72 per cent) are applied. For the purpose of this paper only specific information related to the perception of work stress among public sector managers is analyzed (n=400).
Findings
The perception of stress are influenced by factors like gender, managerial level, work load, the influence on own job situation, if they have children living at home as well as the percentage of work-at-home.
Research limitations/implications
In a general survey work stress is one among a larger number of issues. This fact may influence the validity of the information – in a positive as well as a negative way. However, the findings point to issues which call for more in-depth analyses.
Practical implications
The identified significant determinants influencing the perception of stress point to issues where preventive initiatives can be taken.
Social implications
Since work-related stress may cause absence from work it may influence production and the health system. If preventive measures can be taken a positive impact on the economy may be the result.
Originality/value
Work-related stress has been studied before. But little focus has been given to the public sector and especially managers. Furthermore, including a variety of potential explanatory determinants such a work-life balance, psycho-social work characteristics, gender and managerial level – as well as the potential interaction between them – give a detailed platform for the analyses.

Abstract
Presents the second in a series of two articles tracing the saga of the organizational culture literature from the organization development model through to the recent interest in total quality management (TQM), forming a link between the three concepts. It is argued that, while TQM has separate origins from the culture movement, the two fields have recently converged with the idea that to achieve “excellence” and “quality”, it is necessary either to change or work with the culture of an organization. Following on from the first article which dealt with literature that was mainly of academic interest, such as concepts and methods of study, diagnosis and measurement, reviews the literature that heralds and then reflects the growing interest in utilitarianism. This literature is concerned with attempts to study, implement and measure culture change, and with the emerging relationship between culture and TQM.
