Perceived Workplace Gender Discrimination and Employee Consequences: A Meta-Analysis and Complementary Studies Considering Country Context
Authors: Triana María del Carmen , Jayasinghe Mevan , Pieper Jenna R. , Delgado Dora María , Li Mingxiang
Published: June 2018

We draw on relative deprivation theory to examine how the context influences the relationship between employees’ perceptions of gender discrimination and outcomes at work using a meta-analysis and two complementary empirical studies. Our meta-analysis includes 85 correlations from published and unpublished studies from around the world to assess correlates of perceived workplace gender discrimination that have significant implications for employees. We extend relative deprivation theory to identify national differences in labor laws and cultural norms as contextual factors that affect the threshold for feeling deprived and moderate the relationship between perceived workplace gender discrimination and employee outcomes. Findings show that perceived gender discrimination is negatively related to job attitudes, physical health outcomes and behaviors, psychological health, and work-related outcomes (job-based and relationship-based). Correlations between perceived workplace gender discrimination and physical health outcomes and behaviors were stronger in countries with more broadly integrated labor policies and stringently enforced labor practices focused on promoting gender equality. Correlations were also stronger in countries with more gender-egalitarian cultural practices across multiple employee outcomes of perceived workplace gender discrimination. Further, results from two complementary studies (one employee survey and one experiment) supported the meta-analytic findings and provided evidence of the relative deprivation rationale central to our theory. Implications for research and practice include the need to consider the influence of the country context in organizational decisions to prevent and address gender discrimination and its consequences for employees and ultimately, for employers.
Remaking the set: innovation and obsolescence in television’s digital future
Authors: Chirumamilla Padma
Published: June 2018

In this article, I examine how television’s shifting presence in an unfamiliar venue – the repair shop – is illustrative of a broader tension between rhetorics of innovation and obsolescence. Investigating the nature of this tension, I argue, is crucial for understanding how television is changing in India. Through interviews with small-town and rural television repairmen in south India, and an ethnographic study of a small-town television repair shop, I explore how studying the television as a material object with a distinct life outside the walls of the home and the experiences of the individual viewer can open up new veins of analysis for scholars of television, both in India and elsewhere. Furthermore, I argue that the technological instability on display in the repair shop challenges persistent notions of a technologically empowered ‘digital’ future that have been promulgated by state governments in India.
Deep Time and Secular Time: A Critique of the Environmental ‘Long View’
Authors: Skrimshire Stefan
Published: June 2018

The Anthropocene concept allows human history to be imagined within the temporal framework of planetary processes. Accordingly, some environmentalists increasingly favour massively lengthening the temporal horizons of moral concern. Whilst there are defensible reasons for doing so, I wish to take issue with the ‘secular time’ perspective underlying some such approaches. To make my case, I present, in the first section, two recent manifestations of the long view perspective: a) ‘deep future’ narratives in popular climate science and futurism; b) the ideas behind the Long Now Foundation. In the second section, I apply a critical lens to these perspectives via classic analyses of secular time by Charles Taylor, Hannah Arendt and Giorgio Agamben. I conclude by suggesting that these post-secular critiques should be considered alongside recent approaches to the Anthropocene and the ‘geological turn’ from new materialist perspectives.
Seventeenth-Century Pamphlets as Constituents of a Public Communications Space: A Historical Critique of Public Sphere Theory
Authors: Verhoest Pascal
Published: June 2018

A public sphere in which people can freely discuss worldly affairs is arguably an essential building block of deliberative democracies. As a theoretical and historical concept, however, the public sphere concept is far from unequivocal. This article reviews Habermasian public sphere theory and particularly his failure, according to critics, to establish the ‘bourgeois public sphere’ as an historical category. It provides a more realistic historical account that helps to reframe contemporary conceptions of the public sphere. It argues that the 17th century’s culture of pamphleteering created the space for a proto-public sphere, characterized as a complex network of discursive practices mixing commercial doggerel, state-sponsored propaganda and reasoned argument. These practices were part of contradictory but mutually constitutive processes in the context of religious and political struggles that coincided with the gestation of parliamentary democracy.
Science Artisans and Open Science Hardware
Authors: Kera Denisa
Published: June 2018

Open science hardware (OSH) are prototypes of laboratory instruments that use open source hardware to extend the purely epistemic (improving knowledge about nature) and normative (improving society) ideals of science and emphasize the importance of technology. They remind us of Zilsel’s 1942 thesis about the artisanal origins of science and instrument making that bridged disciplinary and social barriers in the 16th century. The emphasis on making, tinkering, and design transcends research, reproducibility, and corroboration in science and pushes to the forefront educational, emancipatory, and aesthetic and exploratory uses. I will use two recent projects, OpenDrop electrowetting platform and Open Source Estrogen that make but also reflect OSH’s playful, expressive, and performative strategies and define the present practices as “artisanal science.” These hybrid and ambiguous practices bridge divides between present disciplines and skills but they also define science as an everyday activity directly connected to the private and public interests of the citizens. To describe this epistemic and normative ambiguity of artisanal science, I employ Hannah Arendt’s 1958 critique of homo laborans and homo faber and claim that science artisans (citizen scientists, geeks, makers, and hackers) offer an alternative to professionalization of science as practiced in the university and R&D laboratories. Science artisans design and build instruments to engage in civic “vita activa” over instruments but also leisurely “otium” outside of the work and science labor. OSH in this sense empowers individuals and communities to explore new connections between scientific practices, public actions, and private interests (leisure). The science artisans strive for and explore sovereignty, dignity, and freedom in an age immersed in science and technology controversies by bridging the divides between art, science, engineering, and humanities.

Published: June 2018

Diagnosing cancer during pregnancy is uncommon. Although pregnancies with concomitant malignancies have been reported, urological tumours are possibly the most rarely identified tumours during pregnancy. Renal cell carcinoma appears to be the most common urological malignancy during pregnancy. In this case report, we discuss successful management of a patient who was diagnosed with renal cell carcinoma during the antenatal period.

Authors: Xu Wenbo , Zhao Yang , Nian Shiyan , Feng Lei , Bai Xuejing , Luo Xuan , Luo Feng
Published: June 2018

Objective

To investigate the importance of controlling confounding factors during binary logistic regression analysis.

Methods

Male coronary heart disease (CHD) patients (n = 664) and healthy control subjects (n = 400) were enrolled. Fourteen indexes were collected: age, uric acid, cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol, apolipoprotein A1, apolipoprotein B100, lipoprotein a, homocysteine, total bilirubin, direct bilirubin, indirect bilirubin, and γ-glutamyl transferase. Associations between these indexes and CHD were assessed by logistic regression, and results were compared by using different analysis strategies.

Results

1) Without controlling for confounding factors, 14 indexes were directly inputted in the analysis process, and 11 indexes were finally retained. A model was obtained with conflicting results. 2) According to the application conditions for logistic regression analysis, all 14 indexes were weighed according to their variances and the results of correlation analysis. Seven indexes were finally included in the model. The model was verified by receiver operating characteristic curve, with an area under the curve of 0.927.

Conclusions

When binary logistic regression analysis is used to evaluate the complex relationships between risk factors and CHD, strict control of confounding factors can improve the reliability and validity of the analysis.
“House Arrest” or “Developmental Arrest”? A Study of Youth Under House Arrest
Authors: Chamiel Elad , Walsh Sophie D.
Published: June 2018

Studies have examined the potential benefits and risks of alternative forms of detention, such as house arrest, for adults but, despite its growing use, little research has examined the implications of house arrest for juveniles. The current research examined the experience of 14 adolescents under house arrest. Six main themes were identified in the narratives of the participants: the experience of detention, daily schedule and utilization of time, emotions and self-reflection, relationships with peers, relation to parents and supervisor(s), and contact with professionals. Findings emphasized the potential developmental dangers of house arrest at the critical stage of adolescence. Yet, analysis also showed that the period of house arrest has the potential to be a period of positive changes, and can be used for successful rehabilitation.
How Accurately Can We Measure from Video? Practical Considerations and Enhancements of the Camera Calibration Procedure
Authors: Laureshyn Aliaksei , Nilsson Mikael
Published: June 2018

The accuracy of position measurements from videos depends greatly on the quality of the camera calibration model parameters. This paper investigates how such factors as camera height and the selection of calibration points affect the quality of the final calibration model. A series of controlled experiments were performed in traffic or similar-to-traffic environments, in which the accuracy of measurements from videos was compared with measurements taken with other tools. To enhance the calibration process, a multi-camera approach is suggested that utilizes the information about “common points” – points seen on several cameras but with unknown world coordinates. The performed tests showed that calibration quality can greatly benefit from this approach. The paper is addressed primarily to traffic researchers developing their own video-based tools for road user observations.
3-D Data Processing to Extract Vehicle Trajectories from Roadside LiDAR Data
Authors: Sun Yuan , Xu Hao , Wu Jianqing , Zheng Jianying , Dietrich Kurt M.
Published: June 2018

High-resolution vehicle data including location, speed, and direction is significant for new transportation systems, such as connected-vehicle applications, micro-level traffic performance evaluation, and adaptive traffic control. This research developed a data processing procedure for detection and tracking of multi-lane multi-vehicle trajectories with a roadside light detection and ranging (LiDAR) sensor. Different from existing methods for vehicle onboard sensing systems, this procedure was developed specifically to extract high-resolution vehicle trajectories from roadside LiDAR sensors. This procedure includes preprocessing of the raw data, statistical outlier removal, a Least Median of Squares based ground estimation method to accurately remove the ground points, vehicle data clouds clustering, a principle component-based oriented bounding box method to estimate the location of the vehicle, and a geometrically-based tracking algorithm. The developed procedure has been applied to a two-way-stop-sign intersection and an arterial road in Reno, Nevada. The data extraction procedure has been validated by comparing tracking results and speeds logged from a testing vehicle through the on-board diagnostics interface. This data processing procedure could be applied to extract high-resolution trajectories of connected and unconnected vehicles for connected-vehicle applications, and the data will be valuable to practices in traffic safety, traffic mobility, and fuel efficiency estimation.
Examining Head-Down Time in Transportation: Case Study in Single-Pilot General Aviation Operations
Authors: Wilkins Sara A.
Published: June 2018

The “head-down time” problem refers to the potential inability of an operator (e.g., pilot, car driver, or train driver) to divide his or her attention optimally between the primary visual field (e.g., out the window) and an auxiliary tool (e.g., visual display screen). This problem has become an important safety concern in road, rail, and air traffic environments. To improve transportation safety, researchers are applying technology to minimize head-down time. One of these emerging technologies is a pilot-oriented cognitive assistant called the Digital Copilot. The Digital Copilot is a working prototype that provides contextual information and aviation related reminders to the pilot in a timely manner. However, the effects of using this cognitive assistant on the pilot had not been evaluated. This research uses a cognitive task modeling software, called Cogulator, to model a pilot’s expected thoughts and actions and compare them across two different environments: one using the Digital Copilot and one using three different electronic flight bags (EFBs) without cognitive assistance. This study examines how effectively the cognitive assistant can manage mental effort, simplify tasks, and decrease head-down time during preparation for the approach phase of flight for the following five tasks: determine weather frequency, determine communication frequency, review and follow a checklist, determine if the tower is open, and determine the preferred landing runway. Results show that the Digital Copilot provides: time savings in all tasks except for determining weather frequency; savings in head-down time for all tasks; and working memory load savings, or no change, for all tasks.
A Load-Testing Program on Large-Diameter (66-Inch) Open-Ended and PSC-Instrumented Test Piles to Evaluate Design Parameters and Pile Setup
Authors: Haque Md. Nafiul , Abu-Farsakh Murad Y. , Nickel Chris , Tsai Ching , Rauser Jesse , Zhang Zhongjie
Published: June 2018

This paper presents the results from a pile load testing program for a bridge construction project at Chalmette, Louisiana. The load testing includes three 66-in. spun-cast post-tensioned open-ended cylinder piles and one 30-in. square prestressed concrete (PSC) pile driven at four different locations along the bridge site in clayey-dominant soil. Both cone penetration tests and soil borings/laboratory testing were used to characterize the subsurface soil conditions. All test piles (TP) were instrumented with strain gauges to measure the load distribution along the length of the TPs and to measure the side and tip resistances, separately. Dynamic load tests (DLT) were performed on all TPs at different waiting periods after pile installations to quantify the amount of setup (i.e., increase in pile resistance with time). Case Pile Wave Analysis Program (CAPWAP®) analyses were performed on the DLT data to calculate the resistance distributions along the TPs. A static load test was performed only on the PSC pile and statnamic load tests (SNLT) were conducted on both pile types. Design parameters such as the total stress adhesion factor, α, and the effective stress coefficient, β, were back-calculated. The α values ranged from 0.41 to 0.86, and the β values ranged from 0.13 to 0.29. The load test results showed that SNLT overestimated the tip resistance as compared with dynamic and static load tests. Moreover, the pile tip resistance was almost constant during the testing period, and setup was mainly attributed to increase in pile side resistance with time.
Analysis of Asphalt Oxidation by Means of Accelerated Testing and Environmental Conditions
Authors: Villegas-Villegas Rafael E. , Baldi-Sevilla Alejandra , Aguiar-Moya José Pablo , Loria-Salazar Luis
Published: June 2018

The chemical changes that occur to asphalt with oxidation include an increase in oxygen content, as well as the unsaturation of the molecules. This change raises the polarity and stiffness of the material. As a consequence, the elastic response increases, altering its rheology. These transformations are essential to determine pavement performance during its service life. However, the characterization of these chemical and rheological processes cannot be completed because of the inefficiency of current procedures that simulate asphalt oxidation. For this reason, the objective of this study is to characterize asphalt oxidation fundamentally and to relate the observed changes in the materials’ mechanical response. To achieve this goal, a representative group of asphalt samples has been exposed to environmental oxidation, and alternatively to thermal and ultraviolet aging in the laboratory. The samples were characterized chemically and rheologically before the start of the experiment. It was possible to find a correlation between the content of specific chemical species in the material and their mechanical behavior at low and intermediate temperatures. In addition, the present study helps to understand the oxidation phenomena, and helps verify the ineffectiveness of traditional aging techniques, so that they can be modified to simulate the environmental process better.
Three times in the wake: A narrative experience of sensory-anthropology in oceanic outer-places
Authors: Brugidou Jeremie , Clouette Fabien
Published: June 2018

Three times thrown into the wake of ocean incursions. Three times brutally awakened. A semi-fictional anthropologist stumbles in media res upon three different depths or decompression stops, of res in media: (a) at several thousand metres below sea level in a nuclear submarine; (b) at sea level on a fishing trawler; and, finally, (c) deep blue diving at night along a safety line guiding military rescue divers towards a sunken trawler. This is both an essay in individuation and an exploration of associated milieus, inspired by a body of work concerning social constructs of the sea, ocean biopolitics and the oceanization of thought. However, rather than building through theory, we chose to compose through storytelling and body experiment, using interviews and ethnographic materials we collected in 2016. Part dream state, part insomnia, part night work, the narrative deals with our increasingly industrialized mode of existence, affecting our sensory relations to ‘environments’ such as the ocean, but also our sleep and ‘attention’, and the relevance of the ‘anthropocene’ once at sea. Is there anything left of the ‘human’ or the ‘(s)cene’ (terrestrial paradigm) in the movements of the swell and the darkness of the deep?

Published: June 2018

Introduction:

In developing a model of palliative care, the attitudes, needs, and requirements of its beneficiaries recognizing the limited remaining life expectancy need to be met. We aimed to map and compare these issues at the end of life in the groups of patients with advanced cancer and elderly individuals.

Materials and Methods:

The prospective study based on the analysis of semistructured interviews was conducted. Fifty individuals aged older than 85 and 50 incurable patients with advanced cancer were studied. Transcripts of interviews were analyzed qualitatively (the interviews were divided into logically completed themes, and the compliance of each with one of the levels of Abraham Maslow pyramid was determined) and quantitatively (data comparisons of 2 groups were tested in bivariate analysis using Pearson χ2 or Fisher exact test. Two-sided significance tests were used; P value of <.05 was deemed significant).

Results:

It was assumed that 120 themes were relevant to a certain level of Maslow pyramid. Their comparison showed small differences in the narratives of the patients with advanced cancer and elderly individuals aged 85 and older—concerning the past, present, and future terms of lives. In studied themes explicitly prevail the stories that are consistent with satisfaction of the upper levels of the hierarchy of needs and demands of Maslow: social relation (belonging), love, esteem, and transcendence.

Conclusion:

The attitudes, needs, and requirements at the end of life of the people are basically similar, regardless of what determined the sense of limitation of the remaining life—incurable disease or advanced age.
Inpatient Palliative Care Consultations From a Canadian Clinical Teaching Unit
Authors: Maddison André R. , Malik Shiraz , Smaggus Andrew
Published: June 2018

Inpatient palliative care consultation has been demonstrated to improve quality of life as well as decrease hospital readmissions, intensive care unit transfers, and hospital costs for people with a life limiting illness. The clinical teaching units (CTUs) at London Health Sciences Centre (LHSC) routinely admit patients with noncurable cancer as well as end-stage heart, lung, liver, or kidney disease. However, the use of inpatient palliative care consultations for CTU patients remains unexamined. We conducted a descriptive study of all patients referred from LHSC CTU from both University and Victoria hospital to inpatient palliative care over a 1-year period from August 2013 to July 2014. The purpose of this study was to characterize the population and identify possible areas for quality improvement. In a 1-year period, 638 patients were referred from CTU to the inpatient palliative care consultation service. Of referrals, 55% died during their admission. Based on data collected, we conclude that many patients are referred early in their admission to CTU and patients are referred for a variety of noncancer diseases, suggesting knowledge and appreciation of the benefit of early palliative care consultation for malignant and nonmalignant disease. However, when further analyzed, there is indication that patients with noncancer diagnoses are referred statistically significantly later than those with a cancer diagnosis. The CTUs are sites of core medical training, and therefore, it is imperative that we model early integration of palliative care in order to continue to improve care of patients at end of life.
Boys Are Victims, Too: The Influence of Perpetrators’ Age and Gender in Sexual Coercion Against Boys
Authors: Miller Jacqueline A. , Smith Edward A. , Caldwell Linda L. , Mathews Catherine , Wegner Lisa
Published: June 2018

Sexual coercion among adolescent boys in South Africa is an underresearched topic despite the frequency of such events. Although quantitative research has illuminated the prevalence of sexual coercion toward boys, it has provided little understanding of the context of sexual coercion for adolescent boys. Given the often severe consequences of sexual coercion, it is important to further understand these experiences to inform prevention efforts. The current study aims to provide a more nuanced understanding of the context of sexual coercion. Data come from the baseline assessment for a translational research evaluation of a school-based intervention. The current study focuses on a subset of early and middle adolescent boys who reported experiencing sexual coercion ( n = 223). Analyses examine boys’ reports of their perpetrators’ characteristics and details about the sexual coercion encounter. Logistic regression is used to examine how coercion tactics used by the perpetrator differs depending on the perpetrator’s age and gender. Eighth-grade boys were most likely to report that their perpetrator was a similar-aged female and that perpetrator’s age played a particularly important role in what tactics were used. Adult perpetrators were more likely to use physical force, threaten them, harass them electronically, and drink or use drugs at the time. Results provide important insight into boys’ experiences of sexual coercion that have implications for both future research and intervention efforts. Although much research is needed on the topic, intervention programs should recognize that both male and female adolescents can be victim and perpetrator.

Published: June 2018

Lack of social support has shown to be a major risk factor for poor health, mortality, and dementia. We analyzed what factors drive the likelihood of having restricted social networks and to what extent those factors then influence the risk of developing dementia. Our results from the Leipzig Longitudinal Study of the Aged (LEILA75+) indicate that older age (odds ratio [OR]: 1.04) and living with other people (OR: 2.12) was associated with a greater likelihood of having a restricted social network. A better cognitive status (OR: 0.84) was associated with a smaller likelihood of having a restricted social network. The risk of developing dementia over the follow-up period was significantly higher among individuals with restricted (hazard ratio: 2.11) than with integrated social networks. Our findings suggest that integrating elderly individuals in the wider community is a crucial indicator for dementia risk.
Between Kinship and Commerce: Fiduciaries and the Institutional Logics of Family Firms
Authors: Harrington Brooke , Strike Vanessa M.
Published: June 2018

In this study we explore how the institutions of kinship and commerce are integrated within family businesses. Previous research shows that family firms’ characteristic synthesis of institutional logics often unravels during intergenerational successions; however, it remains unclear how this process can be arrested, or by whom. Through inductive analysis, we offer a novel insight: outside advisors can act as surrogates for family in this integrative role. Specifically, we identify fiduciaries—professionals with special client obligations—as key actors in preserving family firms’ viability as commercial enterprises and kinship groups. Our findings contribute to theories of family businesses, professions, and institutions.
Analysis of the surface roughness for novel magnetorheological finishing of a typical blind hole workpiece
Authors: Sirwal Sohaib Ahmad , Singh Anant Kumar
Published: June 2018

In modern high-performance machinery, parts which are highly finished and dimensionally accurate play a vital role. Surface finish enhances characteristics like wear, corrosion, pitting, and oxidation resistance of the surfaces. A novel magnetorheological polishing process using permanent magnets is developed to finish the internal cylindrical and bottom surfaces of the blind hole cylindrical workpiece. The process is capable of finishing the internal cylindrical and flat bottom surfaces of tubular and nontubular-shaped blind hole workpiece. Finishing of blind hole surfaces finds extensive application in dies and automotive components such as automobile actuators, cylinder body, valve seats, etc. In this study, two different tools for finishing the internal and flat bottom surfaces of blind hole cylindrical workpiece have been developed. The causal factor for material removal in the form of microchips is abrasive wear. The present study focuses on the calculation of forces acting on abrasive particles and mathematical modeling and simulation of the surface roughness. The performance of both newly developed tools for finishing the cylindrical blind hole mild steel workpiece is evaluated. After 275 finishing cycles, the Ra values improved by 55.2% in the internal cylindrical ferromagnetic workpiece and by 53.33% after 75,000 cycles on the flat surface of ferromagnetic blind hole workpiece. The theoretical and experimental values of the surface roughness are found to be consistent. The experimental surface roughness values of blind hole internal cylindrical surfaces are within 6.26% of the theoretical values, whereas in finishing the blind hole bottom surface it is found within 7.9% of the theoretical values.
Application of pulse width modulation and by-pass valve control for increasing energy efficiency of pneumatic actuator system

Published: June 2018

Control of a pneumatic actuator using pulse width modulation (control) represents a good alternative for control of pneumatic actuator that uses proportional valve. Important advantage of pulse width modulation control is fewer consumption of compressed air. In addition, air consumption can be further reduced by the use of inter-chamber cross flow (chamber by-passing). This article discusses joint application of pulse width modulation and by-pass chamber control on the example of pneumatic rodless cylinder which is controlled by programmable logic controller. Saving of compressed air was experimentally determined, as well as the influence of inter-chamber cross flow on the quality of the control. With this application of pulse width modulation and by-pass valve control, pneumatic actuator system shows that 30% of energy can be saved under the same working conditions in comparison to the traditional pulse width modulation control system.
Olfactory Ensheathing Cells for Spinal Cord Injury
Authors: Yao R. , Murtaza M. , Velasquez J. Tello , Todorovic M. , Rayfield A. , Ekberg J. , Barton M. , St John J.
Published: June 2018

Olfactory ensheathing cells (OECs) are glia reported to sustain the continuous axon extension and successful topographic targeting of the olfactory receptor neurons responsible for the sense of smell (olfaction). Due to this distinctive property, OECs have been trialed in human cell transplant therapies to assist in the repair of central nervous system injuries, particularly those of the spinal cord. Though many studies have reported neurological improvement, the therapy remains inconsistent and requires further improvement. Much of this variability stems from differing olfactory cell populations prior to transplantation into the injury site. While some studies have used purified cells, others have used unpurified transplants. Although both preparations have merits and faults, the latter increases the variability between transplants received by recipients. Without a robust purification procedure in OEC transplantation therapies, the full potential of OECs for spinal cord injury may not be realised.
Those Numbered Days: An Autoethnography on Living and Dying with a Cancer Patient
Authors: Nath Suman
Published: June 2018

Doing research on cancer patients often involves painful journeys through the processes of involvement and detachment with research settings and participants. It is a self-transforming event to see close cared for people die. Yet frequently these experiences remain unreported in academic writing. The present article attempts to depict the narratives of attachment in the context of terminal illness and detachment as a consequence of death of the research participant, Jabbar, to reflect on such a journey. It focuses on the formation of a relationship beyond the boundaries of the purposes of research to reflect on two related issues, first, the nature of attachments and relationship building that goes in parallel to the formal dimensions of the research, and second, emotions, self-transformation and contextual embeddedness of doing research with terminally ill cancer patients.
Contested industrial democracy discourses in transnational companies. The case of the ArcelorMittal European Social Dialogue Group
Authors: González Begega Sergio , Köhler Holm-Detlev , Aranea Mona
Published: June 2018

This article discusses the potential of European transnational company agreements for developing industrial democracy at European company level. It describes the experience of the ArcelorMittal European Social Dialogue Group, established in 2009 through a European transnational company agreement as an innovative channel for trade union involvement in corporate decision-making. The conceptual framework draws on a cross-national comparison of industrial democracy discourses in two European countries, Germany and Spain. A qualitative approach based on semi-structured interviews with trade union representatives and management is used to identify divergent national discourses of employee voice giving rise to common misunderstandings of industrial democracy at European level. The findings illustrate the persisting communication challenges faced by trade unions when engaging in employee representation structures at transnational company level. The article also shows that trade union representatives are able to adapt their national discourses on industrial democracy under the influence of European practice.
Dynamical response identification of a class of nonlinear hysteretic systems
Authors: Carboni Biagio , Lacarbonara Walter , Brewick Patrick T , Masri Sami F
Published: June 2018

The experimental dynamical response of three types of nonlinear hysteretic systems is identified employing phenomenological models togheter with the Differential Evolutionary algorithm. The mass–spring–damper system is characterized by hysteretic restoring forces provided by assemblies of shape memory and steel wire ropes subject to flexure or coupled states of tension and flexure. The energy dissipation due to phase transformations and inter-wire friction and the stretching-induced geometric nonlinearities give rise to different shapes of hysteresis cycles. The mechanical device subject to strong seismic excitations is investigated in its ultimate limit state whereby inelastic strains are induced in the steel wires together with a global nonsymmetric response of the system. The targeted dynamical characterization of the hysteretic oscillator up to its ultimate limit state has a special meaning when the device is employed in the field of vibration control. The dynamical response is identified exploiting the measurements of the oscillating mass relative displacement and inertia force that must be balanced, at each time instant, by the overall restoring forces provided by the mechanism. The restoring force is assumed to be the sum of different contributions such as a cubic nonsymmetric elastic force and a nonsymmetric hysteretic force modeled according to a modified version of the Bouc–Wen model. The parameters are identified minimizing the difference between the numerical and the experimental restoring force histories. High levels of accuracy are achieved in the identification with mean square errors lower than 2%.
Bridging Analysis and Action

Published: June 2018

This article calls for recognition of ways in which feminisms have, do, and can inform social justice work in technical and professional communication (TPC)—even social justice work that is not explicitly feminist. The authors distill some areas of feminist TPC scholarship that are relevant to future social justice work: (a) epistemological contributions, ways of knowing and methods for discovering them and (b) reclamations of dominant topics, groundwork laid by feminist research on technology and science. They close with nine recommendations to inspire scholars with specific ways to use feminist methodologies and theories to enhance social justice scholarship.
Five-Factor Personality Traits and RIASEC Interest Types: A Multivariate Meta-Analysis
Authors: Hurtado Rúa Sandra M. , Stead Graham B. , Poklar Ashley E.
Published: June 2018

Determining the relationships between five-factor model (FFM) personality dimensions and Realistic, Investigative, Artistic, Social, Enterprising, and Conventional (RIASEC) types is important for counselors and clients during the career choice process. There have been mixed findings regarding this relationship, necessitating this research. The purpose of this study was to determine the relationship between the FFM and RIASEC interest types employing a multivariate meta-regression meta-analysis. Thirty-four studies with 43 independent samples comprising 19,872 participants were employed. Moderator variables included mean age, country of sample, publication year, and FFM and RIASEC Measurement Scales. Estimated correlations between FFM and RIASEC scores ranged from −.08 to .36 suggesting that personality and interests are more distinct constructs than previously thought. FFM Measurement Scales and RIASEC scores by country of sample are important moderating variables in the FFM-RIASEC relationship. The findings have important implications for counseling and research.
Sickness Absence Recommendation Among Outpatients With ADHD and Comorbidity: A Latent Class Analysis
Authors: Trantou Aikatarini , Carlsen Hanne K. , Anderson Christina , Steingrimsson Steinn
Published: June 2018

Objective: Determine sickness absence recommendation (SAR) prevalence for treatment-seeking patients with ADHD depending on comorbidity. Method: Population-based patient chart review of ADHD outpatients aged 19 to 29 years. The outcome, SAR, included both available financial benefit forms; activity compensation and sickness benefit. Latent class analyses (LCA) of demography and psychiatric comorbidities were performed both with and without SAR as an outcome variable. Results: Overall, 38% received SAR. Latent classes ranged from a from a small class of only females with personality disorders where all had SAR to larger groups characterized by lower comorbidity where 15% to 29% had SAR. In between these extremes were other classes of (a) neurodevelopmental disorders, for example, autism diagnosis or intellectual disabilities, and (b) high rate of anxiety disorder, where SAR rates ranged 46% to 65%. Conclusion: Treatment-seeking ADHD patients can be categorized into clinically relevant subgroups providing opportunities to structure rehabilitation efforts to the individuals’ needs.

Published: June 2018

Objectives:

Despite being approved and effective, steroids, and especially dexamethasone intravitreal implants, still have a poorly-defined role in management of diabetic macular edema. In order to overcome some of the limitations in current recommendations, a group of experts met to define consensus on some of the most controversial issues on the use of dexamethasone intravitreal implants in daily management of diabetic macular edema.

Methods:

A Delphi-based approach was utilized to develop clinically relevant statements applicable to routine treatment settings. A Steering Committee composed of four experts formulated 30 relevant statements, which were voted upon by a panel of 40 ophthalmologists/retinal specialists from across Italy.

Results:

Dexamethasone intravitreal implants were considered to be a valid first-line alternative to treatment with an anti–vascular endothelial growth factor agent and should be the first choice in pseudophakic and vitrectomized patients. A Pro Re Nata regimen was felt to be appropriate for retreatment with dexamethasone intravitreal implants while a 6-month waiting period was not considered suitable. Among steroid treatments, dexamethasone intravitreal implants were considered to have the best ocular tolerability. In patients with persistent macular edema after the loading-phase treatment with an anti–vascular endothelial growth factor, consensus was reached that clinicians should consider switching therapy to dexamethasone intravitreal implants. Moreover, dexamethasone intravitreal implants can reduce the treatment burden for individuals who are not able to cope with the more intensive treatment regimen required by anti–vascular endothelial growth factor therapy.

Conclusions:

While further studies are needed, this survey provides some key recommendations for clinicians treating diabetic macular edema that may be useful when choosing dexamethasone intravitreal implants in daily practice.

The purpose of this study was to investigate the physiological and mental health effects caused by exposure to low-frequency noise in typical control rooms and office-like areas. The participants were 35 male students who were exposed to noise at levels of 55, 65, 70, and 75 dBA. The N-back test was used at three cognitive performance loads (low workload ( n = 1), medium workload ( n = 2), and high workload ( n = 3) to evaluate working memory simultaneously in an air conditioning chamber in four sessions with a constant level. The electroencephalography, electrocardiogram, and electrooculography were measured using Nexus 4 by Bio traces software (Mind Media Co.). For evaluation of mental fatigue, fatigue visual analog scale, and psycho-physiological indices were also used. The results showed that the losses of physiological and mental health were rapidly increased with exposure to noise levels of 65–75 dBA. The results showed that mental fatigue significantly affected heart rate, low- to high-frequency ratios, and electroencephalogram indices such as theta, alpha, as well as eye activities and working memory. The findings confirmed that the mental fatigue caused by low-frequency noise significantly impacted the employees’ psycho-physiological and working memory responses. Implementation of the effective interventions to overcome employees’ mental fatigue in typical control rooms and office-like areas can improve the health and acoustic comfort and, consequently, the cognitive performance.
Tourism, the environment, and energy policies

Published: June 2018

This article examines the impact of tourism development on carbon dioxide (CO2) emissions for Organization for Economic Co-operation and Development (OECD) countries by particularly exploring the role of energy markets in the environment–tourism relation. We find that tourism growth raises more CO2 emissions in the future, and that greater CO2 emissions return a lagged and negative impact on tourism development. Our empirical results suggest that an improvement in energy efficiency simultaneously benefits the sustainability of both tourism development and the environment.
Remapping the teacher knowledge-base of language teacher education: A Vietnamese perspective
Authors: Van Canh Le
Published: June 2018

Situated in the Vietnamese context, this article argues that rather than sideline knowledge of learners in favour of subject matter knowledge and pedagogical content knowledge as the basis of the knowledge base of LTE, prominence should be given to knowledge of learners if teachers’ competence to teach responsively is desired.
Academic English as standard language ideology: A renewed research agenda for asset-based language education
Authors: MacSwan Jeff
Published: June 2018

The author situates language education policy and scholarship on Academic English within the broader historical context of standard language ideology, the view that the language variety of socio-economic elites is intrinsically more complex than other varieties. It is argued that the current predominant focus on the nature of school language gives the impression that school language alone can express complex ideas or use complex grammar, leaving little conceptual space for leveraging children’s home language varieties. The author calls for a return to historical commitments to an asset-based approach to school and home language differences in mainstream language education research.
Development of acoustic target strength near-field equation for underwater vehicles

Published: June 2018

For modern weapon systems, the most important factor in survivability is detection capability. Acoustic target strength is a major parameter of the active sonar equation. The traditional target strength equation used to predict the re-radiated intensity for the far field is derived with a plane-wave assumption. In this study, a near-field target strength equation was derived without a plane-wave assumption for a polygonal plate. The target strength equation for polygonal plates, which is applicable to the near field, is provided by the Helmholtz–Kirchhoff formula that is used as the primary equation for solving the re-radiated pressure field. A generalized definition of the sonar cross section is suggested that is applicable to the near field. In comparison experiments for a cylinder, the target strength equation for polygonal plates in near field was executed to verify the validity and accuracy of the analysis. In addition, an underwater vehicle model was analyzed with the developed near-field equation to confirm various parameter effects such as distance and frequency.
