Supervisor humor and employee job performance: A moderated mediation model of work enjoyment and suspicion of the supervisor
Authors: Gkorezis Panagiotis 
Published: August 2020

AbstractSupervisor humor has been shown to be related to various employee outcomes. In this vein, prior research has demonstrated the positive role of supervisor humor in increasing employee job performance. However, little is known about the mediating and moderating mechanisms that explain this relationship. Addressing this gap, the present study develops and tests a moderated mediation model by highlighting work enjoyment as a mediator and suspicion about the supervisor as a moderator. Results from a sample of 190 employees working in a large retail organization showed that work enjoyment mediates the relationship between supervisor humor and subordinates’ job performance and, further, that this indirect effect is dependent upon suspicion of the supervisor.
Invektivität und Geschichtswissenschaft. Konstellationen der Herabsetzung in historischer Perspektive – ein Forschungskonzept
Authors: Schwerhoff Gerd 
Published: August 2020

Zusammenfassung
Angesichts populistischer Feindsetzungen und digitaler Hassreden ist gegenwärtig die Wahrnehmung weit verbreitet, in einem Zeitalter der Schmähung und Herabwürdigung zu leben. Der Beitrag nimmt die historischen Dimensionen des Themas in den Blick und plädiert für das neue Konzept der „Invektivität“ als Instrument umfassender Analyse. Nachdem er existierende Anknüpfungspunkte in den Geschichts- und Kulturwissenschaften durchmustert hat, skizziert er Grundzüge dieses Konzeptes. Invektivität soll – jenseits einzelner Gattungsbezeichnungen – jene Aspekte von Kommunikation bezeichnen (ob mündlich oder schriftlich, ob gestisch oder bildlich), die dazu geeignet sind, Personen oder Gruppen herabzusetzen, zu verletzen oder auszugrenzen. Dabei wird der Schlüssel für die Bedeutungen invektiver Kommunikation nicht in der Motivation einzelner Sprecher gesucht; vielmehr konstituieren sie sich, modellhaft gesprochen, im Kraftfeld einer triadischen Konstellation von Akteuren und werden entscheidend vom jeweiligen Kontext sowie von der Anschlusskommunikation bestimmt. Diese Beobachtung und weitere im Beitrag aufgeführte Charakteristika von Invektivität führen zu dem Schluss, dass Invektivität in Geschichte und Gegenwart enorme gesellschaftliche Funktionen entfaltet. Das betrifft nicht nur ihr offenkundig destruktives Potential, sondern auch ihre produktive, gruppen- und gesellschaftsbildende Kraft. Im letzten Teil des Beitrages wird das Konzept exemplarisch an einem Arbeitsfeld der Geschichtswissenschaft erprobt, nämlich im Hinblick auf die Person Martin Luthers und das Problem der Öffentlichkeit im Reformationszeitalter.
Gerechter Lohn oder „Bourgeois-Sinecure“? Die Debatte um die Gewinnbeteiligung des Aufsichtsrats um 1900
Authors: Selgert Felix 
Published: August 2020

Zusammenfassung
Im Deutschen Kaiserreich existierten um die Jahrhundertwende hohe Lohnungleichheiten. Eine kleine Gruppe von Spitzenverdienern, ein Prozent der Lohnempfänger, beanspruchte im ersten Jahrzehnt des 20. Jahrhunderts fast ein Fünftel der gesamten Lohnsumme für sich. Zu dieser Gruppe gehörten auch viele Aufsichtsräte von Aktiengesellschaften. Diese Lohnungleichheiten blieben den Zeitgenossen nicht verborgen und erreichten um die Jahrhundertwende den Reichstag. Dort entspann sich im Kontext der Steuerdebatten der 1900er Jahre eine Debatte um soziale Gerechtigkeit. Politiker des Zentrums und der konservativen Reichsparteien kritisierten Aufsichtsratsentschädigungen, weil diese ohne Arbeitsleistung zustande kämen. Insbesondere in den Augen der Zentrumspolitiker gefährdete dies den Zusammenhalt der Gesellschaft. Liberale Politiker verteidigten die Spitzeneinkommen dagegen, indem sie auf das Haftungsrisiko und die hohe Arbeitsbelastung der Aufsichtsräte hinwiesen. Die vor allem von der Zentrumspartei propagierte Norm der sozialen Gerechtigkeit fand Eingang in wirtschaftspolitische Maßnahmen, die auf die Beschränkung der Aufsichtsratsvergütungen abzielten. In der Praxis scheinen diese Maßnahmen jedoch keine Wirkung entfaltet zu haben. Die empirische Untersuchung der Vergütungen von Aufsichtsräten anhand eines großen Unternehmensdatensatzes zeigt, dass viele Aktiengesellschaften die beabsichtigte Vergütungsbeschränkung durch die Einführung neuer Vergütungsformen umgingen. Wertvorstellungen in Bezug auf Lohnungleichheiten beeinflussten somit durchaus politischen Gestaltungswillen, hatten aber kaum Einfluss auf die Praxis der Lohngestaltung von Spitzenmanagern.
Mixed Reality based Collaboration for Design Processes

Published: August 2020

AbstractDue to constantly and rapidly growing digitization, requirements for international cooperation are changing. Tools for collaborative work such as video telephony are already an integral part of today’s communication across companies. However, these tools are not sufficient to represent the full physical presence of an employee or a product as well as its components in another location, since the representation of information in a two-dimensional way and the resulting limited communication loses concrete objectivity. Thus, we present a novel object-centered approach that compromises of Augmented and Virtual Reality technology as well as design suggestions for remote collaboration. Furthermore, we identify current key areas for future research and specify a design space for the use of Augmented and Virtual Reality remote collaboration in the manufacturing process in the automotive industry.
Communicating Robotic Help Requests

Published: August 2020

Abstract
In this paper we report results from a web- and video-based study on the perception of a request for help from a robot head. Colored lights, eye-expressions and politeness of the used language were varied. We measured effects on expression identification, hedonic user experience, perceived politeness, and help intention. Additionally, sociodemographic data, a ‘face blindness’ questionnaire, and negative attitudes towards robots were collected to control for possible influences on the dependent variables. A total of n = 139 participants were included in the analysis. In this paper, the focus is placed on interaction effects and on the influence of covariates. Significant effects were found for the interaction of LED lighting and eye-expressions and for language and eye-expressions on help intention. The expression identification is significantly influenced by the interaction of LED lighting and eye-expressions. Several significant effects of the covariates were found, both direct and from interaction with independent variables. Especially the negative attitudes towards robots significantly influence help intention and perceived politeness. The results provide information on the effect of different design choices for help requesting robots.

AbstractThe purpose of this article is to review the literature regarding the relationships between alexithymia, fibromyalgia (FM), and psychological distress among adolescents. Google Scholar and databases were searched using alexithymia, fibromyalgia, psychological distress, and adolescent keywords. Studies that examine the relationship between alexithymia and fibromyalgia and the contribution of psychological distress on this relationship among adolescents are lacking. However, based on previous studies on adult samples and theoretical background, there are possible relationship between alexithymia and fibromyalgia as well as possible mediating effect of psychological distress on this relationship in adolescents. Further studies are recommended to examine the relationships between alexithymia, fibromyalgia, and psychological distress among adolescents.
Estimating the area under a receiver operating characteristic curve using partially ordered sets
Authors: Zamanzade Ehsan , Wang Xinlei 
Published: August 2020

Abstract
Ranked set sampling (RSS), known as a cost-effective sampling technique, requires that the ranker gives a complete ranking of the units in each set. Frey (2012) proposed a modification of RSS based on partially ordered sets, referred to as RSS-t in this paper, to allow the ranker to declare ties as much as he/she wishes. We consider the problem of estimating the area under a receiver operating characteristics (ROC) curve using RSS-t samples. The area under the ROC curve (AUC) is commonly used as a measure for the effectiveness of diagnostic markers. We develop six nonparametric estimators of the AUC with/without utilizing tie information based on different approaches. We then compare the estimators using a Monte Carlo simulation and an empirical study with real data from the National Health and Nutrition Examination Survey. The results show that utilizing tie information increases the efficiency of estimating the AUC. Suggestions about when to choose which estimator are also made available to practitioners.
Catalytic combustion of propane on Pd-modified Al–La–Ce catalyst – from reaction kinetics and mechanism to monolithic reactor tests and scale-up

Abstract
A propane combustion catalyst was prepared by supporting of Pd on optimized multiphase composition, containing Al2O3, La2O3 and CeO2 aiming for possible application in catalytic converters for abatement of propane in waste gases. The catalyst characterization has been made by N2- physisorption, XRD, SEM/EDX, TEM and XPS. The obtained values for reaction order towards propane and oxygen are 0.57 and 0.14, respectively. The negative reaction order towards the water vapour (−0.26) shows an inhibition effect of the water molecules. According to the kinetics model calculations, the reaction pathway over Pd-modified La–Ce catalyst proceeds most probably through Langmuir–Hinshelwood mechanism with adsorption of propane and oxygen on different types of sites, dissociative adsorption of oxygen, whereupon water molecules compete with propane molecules for one and the same type of adsorption sites. For practical evaluation of the synthesized material, a sample of Pd/Al2O3–La2O3–CeO2, supported on rolled Al-containing stainless steel (Aluchrom VDM®) to form a single monolithic channel was prepared and tested. Two-dimensional heterogeneous models were used to simulate the propane combustion from laboratory reactor to full-scale adiabatic monolithic converter for ensuring an effective abatement of propane emissions.

AbstractWhey is a high strength waste product of cheese manufacture. Anaerobic digestion of cheese allows pollution potential reduction and simultaneously energy production. Organic loading rate (OLR) is an important operating variable for anaerobic digestion (AD) process related to system stability, waste treatment capacity and biogas production. The actual OLR depends on the types of wastes (i.e., content of chemical oxygen demand [COD]) fed into a digester. In this paper, the effect of OLR on the AD process of the raw cheese whey in a semi-continuous up-flow system is studied experimentally and with numerical simulations using a simple dynamical model calibrated with experimental data. The digester operation was performed for 90 days, doubling the OLR every 30 days, from OLR of 2.5–10 gCOD L−1 d−1. Experimental results show that the increase in OLR favors the production of biogas. However, the proportion of methane may decrease. The highest methane yield and the most considerable substrate degradation were obtained at OLR of 5 gCOD L−1 d−1 and 10 gCOD L−1 d−1, respectively. The proposed mathematical model is used to describe the dynamic behavior of key variables as COD, volatile fatty acids (VFA) and methane production. A good fit between the variables estimated by the mathematical model and experimental data was obtained, reaching determination coefficients (R2) greater than 0.8. Therefore, this model might be beneficial in predicting the maximum methane production rate and the maximum OLR that could be used without risking the AD process stability.

Published: August 2020

Abstract
It was hypothesized that inhibition zone of an essential oil (EO) in a Petri dish might be relevant to its diffusion coefficient (DC) into agar medium, which may be calculated from the Fick’s diffusion. Antibacterial activities of cumin, dill weed, fennel, ginger and oregano EOs were evaluated against Campylobacter jejuni and Campylobacter coli. DCs, zeta potential and droplet sizes of EOs were measured. The inhibition zones of EOs had in accordance with DCs whereas they had a reverse relation with droplet size. The measured DCs were in the range of 0.82–1.50 × 10−12 m2 s−1. The effective DC of EOs calculated from the total flux exhibited good correlations with measured DCs. Outcomes of this study may provide a pre-assessment for the antimicrobial activity of any EOs from its DC. Furthermore, it may help to understand the studies on how EOs pass through a bacterium cell and show antimicrobial effects.

Published: August 2020

Abstract

Objectives
Clinical practice is a major component of nursing education wherein significant learning takes place. Nursing students experience stress in clinical practice which can have a negative impact on their learning. Guided by Lazarus and Folkman’s theory of stress and coping, this study explored nursing students’ perceptions of and experiences with coping with stress in clinical practice.

Methods
Semi-structured interviews were conducted with ten undergraduate nursing students. Qualitative content analysis was used to analyze the data.

Results
The themes of: Learning about self, Knowing self, Value of social support, and Relationships with clinical instructors reflect participants’ descriptions of coping with stress. Students cognitive and behavioral strategies, including reflection, help them understand their stress and decide how to reduce its effects.

Conclusions
Supportive and respectful relationships are essential for a student to learn and cope effectively with stressful situations. Implications for improving the clinical instructor’s role to enhance students’ coping with stress in clinical practice are discussed.
Global exponential stability analysis of anti-periodic solutions of discontinuous bidirectional associative memory (BAM) neural networks with time-varying delays
Authors: Fu Xiangying , Kong Fanchao 
Published: August 2020

Abstract
This paper is concerned with a class of bidirectional associative memory (BAM) neural networks with discontinuous activations and time-varying delays. Under the basic framework of differential inclusions theory, the existence result of solutions in sense of Filippov solution is firstly established by using the fundamental solution matrix of coefficients and inequality analysis technique. Also, the boundness of the solutions can be estimated. Secondly, based on the non-smooth Lyapunov-like approach and by construsting suitable Lyapunov–Krasovskii functionals, some new sufficient criteria are given to ascertain the globally exponential stability of the anti-periodic solutions for the proposed neural network system. Furthermore, we have collated our effort with some previous existing ones in the literatures and showed that it can take more advantages. Finally, two examples with numerical simulations are exploited to illustrate the correctness.
Language, employability and positioning in a Danish integration programme
Authors: Lønsmann Dorte 
Published: August 2020

AbstractIn many European countries, integration policies focus on getting refugees quickly into the labour market. In order to accomplish this, refugees in Denmark are placed in work internships. Based on fieldwork in an integration programme that combines mandatory Danish language classes with so-called “language internships”, where refugees do work internships for the purpose of learning Danish at work, the present study takes a critical look at discourses and positionings related to refugee access to the Danish labour market. The study finds clear evidence of an employability discourse which emphasises individual responsibility for employment while downplaying structural factors. Paradoxically, the employability discourse positions the refugees on the one hand as unemployable because of their lack of Danish language competence and hence as marginalised and relatively powerless. On the other hand, in this same discourse, they are repeatedly positioned as agents responsible for creating their own opportunities, including employment opportunities, while the language internships are constructed as a means of gaining employment and being able to leave the unemployment system. By investigating acts of positioning by participants in the integration programme and comparing them with discourses on language, work and integration in Denmark, the study concludes that despite intentions about the internships leading to employment and thus empowerment, the language internships lead to decapitalisation and marginalisation for the refugee participants.
Validation of the 8th lung cancer TNM classification and clinical staging system in a German cohort of surgically resected patients
Authors: Taber Samantha , Pfannschmidt Joachim 
Published: August 2020

Abstract

Objectives
The updated 8th edition of the tumor, node, metastases (TNM) classification system for non-small cell lung cancer (NSCLC) attempts to improve on the previous 7th edition in predicting outcomes and guiding management decisions. This study sought to determine whether the 8th edition was more accurate in predicting long-term survival in a European population of surgically treated NSCLC patients.

Methods
We scanned the archives of the Heckeshorn Lung Clinic for patients with preoperative clinical stages of IIIA or lower (based on the 7th edition), who received surgery for NSCLC between 2009 and 2014. We used pathologists’ reports and data on tumor size and location to reassign tumor stages according to the 8th edition. We then analyzed stage specific survival and compared the accuracy of the two systems in predicting long-term survival. We excluded patients with neoadjuvant treatment, incomplete follow-up data, tumor histologies other than NSCLC, or death within 30 days of surgery.

Results
The final analysis included 1,013 patients. Overall five-year survival was 47.3%. The median overall survival (OS) was 63 months (range 1–222), and the median disease-free survival (DFS) was 50 months (0–122). The median follow-up time for non-censored patients was 84 months (range 60–122).

Conclusions
We found significant survival differences between the newly defined stages 1A1, 1A2 and 1A3 (previously 1A). We also found that the 8th edition of TMN classification was a significantly better predictor of long-term survival, compared to the 7th edition.

Wie beeinflusst die Generationszugehörigkeit das Teilen von Wissen in Unternehmen?
Authors: März Sophie , Seo DongBack , Womser-Hacker Christa 
Published: August 2020

Zusammenfassung
Das Teilen von Wissen ist für die heutige Informationsgesellschaft eine der wichtigsten Herausforderungen. Um ein erfolgreiches und innovatives Agieren zum Beispiel in Unternehmen zu ermöglichen, ist eine kontinuierliche Strategie im Umgang mit Wissen und Information unerlässlich. Diese ist abhängig von gutem Wissensmanagement und vor allem von der Bereitschaft, Wissen zu teilen. Da Altersdiversität und damit einhergehende Generationenkonflikte den unternehmerischen Alltag stark prägen, wird in dieser Arbeit auf die Unterschiede zwischen jüngeren und älteren Arbeitnehmern1 eingegangen. Wie können verschiedene Altersgruppen motiviert werden, ihr Wissen zu teilen? Welche Umstände sollten vermieden werden, damit keine Hürden entstehen? Um diesen Fragen nachzugehen, wurde eine Umfrage in deutschen Unternehmen mit einer Rücklaufquote von 236 Personen durchgeführt. Diese veranschaulicht, dass ältere Mitarbeiter mehr dazu tendieren, ihr Wissen zu teilen als ihre jüngeren Kollegen. Vor allem die Befürchtung, sich zu blamieren und Fehler zu machen, scheint der jüngeren Generation Probleme zu bereiten. Für Unternehmen ist es wichtig, Unterschiede und Gemeinsamkeiten zu erkennen, um Strategien und Instrumentarien zu entwickeln, die eine gelungene Interaktion verschiedener Altersgruppen ermöglichen.

Vaccines and the Armed Forces: There “AIN’T” NO “Anti-vaxxers” in the Military
Authors: Rosen Richard 
Published: August 2020

Abstract
As many of you may remember from your first-year Tort and Constitutional Law courses, courts recognize the right of competent adults to refuse medical treatment, even if necessary to save their lives; this generally includes the right to refuse immunizations from diseases, particularly if the vaccine has not yet been approved by the Food & Drug Administration. As you also undoubtedly know, servicemembers are different. To maintain the strength and readiness of the armed forces, military personnel must undergo necessary medical treatment. Otherwise, if they become casualties to disease or other treatable disabilities, servicemembers become burdens on their units, and their jobs must be assumed by others—often leaving their units short-handed. Their illnesses or disabilities thus affect the ability of their units to accomplish their missions and may jeopardize the safety and lives of their fellow servicemembers. Indeed, until World War II, the majority of combat deaths in military units engaged in combat were due to infectious diseases rather than direct combat injuries.
