Do participation structures affect workers’ voice?

Employees’ democratic right to participate is a core element of Nordic labour market models exercised both through representative and indirect participation as well as individual and direct participation. This article analyses representative participation and whether the form it takes matters: Is local trade union representatives’ assessment of influence at company level dependent on whether meetings with management are formal or informal? The question is important because institutional arrangements are on the decline in several European countries. Weaker trade unions and trade union representatives, due to falling unionisation rates, could affect strategic decisions by management when it comes to inviting trade union representatives into decision-making forums. Furthermore, individual-oriented management concepts may be strengthening this trend, in turn challenging the Nordic labour market models at company level. These issues are addressed through power resource perspectives by examining how such resources affect local trade union representatives’ capacity to influence decisions.
Prevalence and Risk Factors of Problematic Internet Use among Hungarian Adult Recreational Esports Players

Background: Esports are highly prevalent in modern culture, particularly among young people, and are a healthy hobby for the majority of users. However, there is a possible link between video gaming (including esports) and problematic internet use (so-called internet addiction, IA), mostly involving adolescents. Methods: Here we present an online survey focusing on the prevalence and risk factors of internet addiction among adult esports players. Demographics included age, gender, family type, type of work, working years and daily internet use. Medical conditions associated with IA such as smoking, alcohol and drug intake, hypertension, diabetes, ischemic heart disease, musculoskeletal pain and history of depression were also recorded. Results: Overall, 2313 players including 176 females (7.6%) and 2137 males (92.4%) participated in our online survey. Age distribution was the following: 18–25 years 90.3% (2088/2313), 26–35 years 7.95% (184/2313), 36–45 years 0.86% (20/2313), 46–55 years 0.82% (19/2313), 56–62 years 0.04% (1/2313) and 62 years or older 0.04% (1/2313). Internet addiction was detected in 19.9% of players (461/2313) based on the Problematic Internet Use Questionnaire. In a multivariate analysis internet addiction was significantly associated with age between 18 and 25 (OR: 1.675, p = 0.002), being single (OR = 1.505, p = 0.014), internet use > 6 h daily (OR = 4.338, p < 0.001), having < 3 children (OR: 2.037, p = 0.023) and having secondary employment (OR = 1.789, p = 0.037). Regular alcohol intake (OR = 18.357, p < 0.001) and history of depression (OR= 5.361, p = 0.032) were also strongly correlated with IA. Conclusion: This is the first study from Hungary investigating the prevalence and risk factors of internet addiction among adult esports players. One out of five adult gamers suffered from IA. Our study also draws attention to increased risk within this group and risk factors such as younger age, family status and type of employment.
Power factor control using brushless doubly fed reluctance machines

The brushless doubly-fed machine (BDFM) allows the use of a partially rated inverter in many variable speed applications with limited speed variations. In its induction machine form (BDFIM), however, the BDFM has significant rotor losses and poor efficiency due to the cage rotor design. A reluctance version of the BDFM, the brushless doubly-fed reluctance machine (BDFRM), ideally has no rotor losses, and therefore offers the potential for greater efficiency and simpler control compared to the BDFIM. A theoretical study of this interesting machine is very important in order to gain a thorough understanding of its unusual operation, control features and compromises between optimal performance and the size of the inverter and the machine. This paper specifically concentrates on power factor control properties of the machine and trade-offs with other control objectives such as maximum torque per inverter ampere and minimum copper losses. To date this kind of analysis has not appeared in the literature.
Regional trade agreements and agricultural trade: An analysis of Zimbabwe’s agricultural trade flows

Abstract The main aim of the study was to assess the impact of Economic Partnership Agreement (EPA) and Southern African Development Community Free Trade Area (SADC-FTA) on Zimbabwe’s agricultural trade flows. Results highlight that Zimbabwe’s membership in EPA initiated in 2012, enhanced the country’s agricultural trade flows by 307.96%. Membership in SADC-FTA initiated in 2008 has enhanced the country’s agricultural trade flows by 437.09%. Other independent variables including exchange rates and GDP negatively impacted the country’s agricultural trade flows. From the empirical findings, it is critical for the government to conduct impact assessments.
A REVIEW ON: SPINAL CORD INFECTIONS

This article consists of infections of the vertebral body, intervertebral disc, ligaments and para-vertebral gentle tissues, epidural space, meninges and subarachnoid space, and the spinal cord. A huge variety of infective organisms can be implicated and the incidence of some, drastically tuberculosis, is growing because of multiplied immune compromised and different factors. Imaging performs a key position in early prognosis of those diseases, which can be extreme and probably life-threatening Infection can also additionally be received by the hematogenous route by infection from contiguous systems or from direct inoculation. Of to be had imaging techniques, CT and MRI provide the clinically most valuable strategies of comparing all the systems probably involved in infection. Although many signs are non-specific, indication is given of in which appearances increase strong suspicion of contamination. The quantity of the inflammatory procedure is well evaluated by imaging, particular lying phrases of severity and morbidity of medical sequelae, which can also additionally be severe. Early research is obligatory and as MRI currently has the key function in research, it must be employed at an early degree of medical suspicion.
A Novel iOS Data Donation Approach: Automatic Processing, Compliance, and Reactivity in a Longitudinal Study

For social scientists who are interested in understanding smartphone-usage patterns, as well as the causes and effects of smartphone use, it is crucial to get accurate estimates of smartphone and app usage. For this reason, we present a novel data donation approach based on screen video recordings of information provided by the iOS Battery Section. In this paper, we describe the Python script that can be used to process the data automatically. Moreover, we tested accuracy of the script, feasibility of the data collection method, as well as compliance and reactivity of the approach among a sample of 93 University students who participated in a 7-day mobile diary study. The findings of the study show that the approach works well, is very feasible and that the script resulted in accurate smartphone use data. Moreover, findings show that compliance rates were rather high, and no substantial signs of reactivity to the method occurred (i.e., participants did not change their smartphone behavior substantially while participating in this study). We therefore hope that the presented approach will encourage future researchers to use this or similar approaches to gain accurate smartphone use data in an ethical way.
Understanding emojis: Cultural influences in interpretation and choice of emojis

ABSTRACT Emojis have been widely used in computer-mediated communication. This study examined how cultural identification with individualism and collectivism influences Americans’ interpretations and choices of emojis commonly used in South Korea. We also investigated the moderating effects of intercultural communication competence (ICC) and emotional intelligence (EI). Results from a sample of college students in the U.S. (N = 369) showed that the identification with individualism and collectivism played a significant role in interpreting and selecting appropriate emojis. Moreover, ICC and EI significantly moderated the relationships. These findings enhance understanding of cross-cultural differences in understanding emojis in CMC.
Selective Decomposition of Waste Rubber from the Shoe Industry by the Combination of Thermal Process and Mechanical Grinding

A major challenge in waste rubber (WR) industry is achieving a high sol fraction and high molecular weight of recycled rubber at the same time. Herein, the WR from the shoe industry was thermo-mechanically ground via the torque rheometer. The effect of grinding temperature and filling rate were systematically investigated. The particle size distribution, structure evolution, and morphology of the recycled rubber were explored by laser particle size analyzer, Fourier transform infrared spectroscopy (FTIR), sol fraction analysis, gel permeation chromatography (GPC), differential scanning calorimeter (DSC), and scanning electron microscope (SEM). The results indicate that the thermo-mechanical method could reduce the particle size of WR. Moreover, the particle size distribution of WR after being ground can be described by Rosin’s equation. The oxidation reaction occurs during thermal-mechanical grinding. With the increase of the grinding temperature and filling rate, the sol fraction of the recycled WR increases. It is also found that a high sol fraction (43.7%) and high molecular weight (35,284 g/mol) of reclaimed rubber could be achieved at 80 °C with a filling rate of 85%. Moreover, the obtained recycled rubber compound with SBR show a similar vulcanization characteristics to pure SBR. Our selective decomposition of waste rubber strategy opens up a new way for upgrading WR in shoe industry.
Cell Membrane Discharge Model Enlightened Robust Attitude Maneuvering Control for Flexible Spacecraft

Under model parametric uncertainties and external disturbances in space,this study investigates attitude maneuvering control for large angle rapid maneuvering and fast stable of flexible spacecraft.A cell membrane discharge model enlightened robust attitude maneuvering control law is designed.To cope with the existing model parametric uncertainties and external disturbances,a robust attitude maneuvering controller is proposed based on the nonlinear and coupled characteristics of flexible spacecraft.The problem of jump of attitude which will excite the elastic vibration mode during large angle maneuver of flexible spacecraft is studied.By using dynamics model of cell membrane discharge,an improved robust attitude maneuvering controller is proposed.When the errors of model parametric uncertainties and external disturbances are bounded,it is proved that the closed-loop system is uniformly ultimately bounded.Finally,by using the control parameters properly,the control performance can be improved and the control energy can be reduced.The simulation results demonstrate the effectiveness of the proposed robust controller.
Insights Into Mechanisms of Oriented Division From Studies in 3D Cellular Models

In multicellular organisms, epithelial cells are key elements of tissue organization. In developing tissues, cellular proliferation and differentiation are under the tight regulation of morphogenetic programs, that ensure the correct organ formation and functioning. In these processes, mitotic rates and division orientation are crucial in regulating the velocity and the timing of the forming tissue. Division orientation, specified by mitotic spindle placement with respect to epithelial apico-basal polarity, controls not only the partitioning of cellular components but also the positioning of the daughter cells within the tissue, and hence the contacts that daughter cells retain with the surrounding microenvironment. Daughter cells positioning is important to determine signal sensing and fate, and therefore the final function of the developing organ. In this review, we will discuss recent discoveries regarding the mechanistics of planar divisions in mammalian epithelial cells, summarizing technologies and model systems used to study oriented cell divisions in vitro such as three-dimensional cysts of immortalized cells and intestinal organoids. We also highlight how misorientation is corrected in vivo and in vitro, and how it might contribute to the onset of pathological conditions.
Beneficial In Vitro Effects of a Low Myo-Inositol Dose in the Regulation of Vascular Resistance and Protein Peroxidation under Inflammatory Conditions

Oxidative stress induces functional changes in arteries. Therefore, the effect of myo-inositol, a possible anti-inflammatory/antioxidant agent was studied on human plasma and rat thoracic arteries. Aortic rings from male Wistar rats (3 months of age) were incubated with myo-inositol (1, 10 and 100 μM, 120 min) and analyzed using the gas chromatography (GC) method. In another experiment, aortic rings were protected first with myo-inositol (1 µM, 60 min) and then subjected to a thromboxane receptor agonist (U-46619, 0.1 nM, 60 min). Therefore, these four groups under the following conditions were studied: (i) the control in the vehicle; (ii) myo-inositol; (iii) the vehicle plus U-46619; (iv) myo-inositol plus U-46619. The hemostatic parameters of human plasma and an H2O2/Fe2+ challenge for lipid and protein peroxidation were also performed. Myo-inositol was not absorbed into the pre-incubated aortic rings as measured by the GC method (0.040 µg/mg, p ≥ 0.8688). The effect of myo-inositol was more significant in the impaired arteries due to U-46619 incubation, which resulted in an improved response to acetylcholine (% Emax: 58.47 vs. 86.69), sodium nitroprusside (logEC50: −7.478 vs. −8.076), CORM-2 (% Emax: 44.08 vs. 83.29), pinacidil (logEC50: −6.489 vs. −6.988) and noradrenaline (logEC50: −7.264 vs. −6.525). This was most likely a possible response to increased nitric oxide release (×2.6-fold, p < 0001), and decreased hydrogen peroxide production (×0.7-fold, p = 0.0012). KCl-induced membrane depolarization was not modified (p ≥ 0.4768). Both the plasma protein carbonylation (×0.7-fold, p = 0.0006), and the level of thiol groups (×3.2-fold, p = 0.0462) were also improved, which was not significant for TBARS (×0.8-fold, p = 0.0872). The hemostatic parameters were also not modified (p ≥ 0.8171). A protective effect of myo-inositol was demonstrated against prooxidant damage to human plasma and rat thoracic arteries, suggesting a strong role of this nutraceutical agent on vasculature which may be of benefit against harmful environmental effects.
Diffusion tensor imaging metrics in diagnosis of HTLV‐1‐associated myelopathy

In the diagnosis of HTLV‐1‐associated myelopathy (HAM), while magnetic resonance imaging (MRI) is essential to exclude other diseases, its power is limited regarding HAM diagnosis, as only 30% of affected patients present with spinal cord atrophy. Diffusion tensor imaging (DTI) may enable the detection of damage in the white matter microstructure. Here, we quantitatively assess spinal cord damage using DTI and evaluate conventional MRI parameters of the spinal cord in HTLV‐1‐infected individuals.
Variation in the density and body size of a threatened foundation species across multiple spatial scales

Population characteristics (e.g. density and body sizes) of foundation species can affect their own persistence and provisioning of ecosystem functions. Understanding the drivers of population characteristics of foundation species at multiple spatial scales is therefore critical for maximizing ecosystem functions of restored habitats. We analyzed variation in population characteristics (densities, 95th percentile, and median lengths of live oysters) of the Sydney rock oyster, Saccostrea glomerata, on remnant oyster reefs at regional scales (among three estuaries) along an approximately 250 km of coastline in New South Wales, Australia. We then analyzed how population characteristics were further related to spatial attributes at smaller spatial scales including within‐patches (rugosity, distance to patch‐edge, and elevation), whole‐patches (size and shape), and among‐patch (connectivity) within each estuary. The densities and body sizes of S. glomerata were related to spatial attributes occurring within‐patch (e.g. elevation), whole‐patch (e.g. shape), and landscape (i.e. connectivity) scales, but these relationships varied among estuaries. The greatest variation in oyster density and size occurred at regional scales, suggesting that processes acting at larger spatial scales (e.g. water quality and/or climate) set the context for smaller scale influences on oyster characteristics. Our results highlight the potential importance of incorporating site‐specific, spatial attributes in the design of restored oyster reefs to maximize ecosystem services and functions provided by restoration efforts.
Impact of Frailty on the Relationship between Blood Pressure and Cardiovascular Diseases and Mortality in Young-Old Adults

The optimal blood pressure (BP) target in older people according to frailty status remains uncertain. This article investigates how frailty affects the association between BP and cardiovascular diseases or mortality, specifically in young-old adults. A retrospective cohort was created for 708,964 older adults with a uniform age of 66 years. The association between BP and myocardial infarction (MI), stroke, or mortality was analyzed using Cox proportional hazards models. The Timed Up and Go test (TUG) was used as a measure of physical frailty. Mean follow-up was 6.8 years, detecting 38,963 (5.5%) events. There was a linear association between increasing systolic BP (SBP) or diastolic BP (DBP) and increased risk of incident MI and stroke, compared to the reference BP (SBP, 110–119 mmHg or DBP, 80–89 mmHg). The risk patterns with high BP remained similar in each TUG group (<10, 10–14, or ≥15 s). A similar pattern of increased risks was found in those who took antihypertensive drugs and who did not, however they were more pronounced in those who did not. The findings support the need to achieve the same BP target in young-old adults with or without frailty to lower the risk of MI, stroke, and mortality.
Entertainment Spending and Capturing Value from Innovation in Chinese Firms

ABSTRACT This study examines how Chinese firms capture value from their innovations. We propose that relationship-building through business entertainment may be helpful. In particular, wining and dining key stakeholders, including clients, suppliers, distributors, and government officials, can help firms gain access to complementary resources necessary for commercializing their innovations, facilitating capturing value from innovations. However, business entertainment is less effective in regions with relatively developed market-supporting institutions, including factor markets and legal institutions. The analysis results of archival data and data from a World Bank survey of Chinese firms support all the above arguments. 摘要 本研究考察了中国企业是否可以通过商务招待的方法促进其创新产品的商业化并获取价值。 我们假设通过商务招待（主要指宴请活动）与利益相关者，包括客户、供应商、分销商和政府官员--建立关系，可以帮助企业获得将其创新商业化所需的互补资源，促进从创新中获取价值。 但是，在要素市场和法律制度等市场支持机构相对发达的地区，商务招待效果较差。 通过对中国上市公司制造型企业在2009-2017数据的分析，以及世界银行对中国企业的调查数据的分析，我们发现结果支持上述所有论点。
The effect of institutional investors’ site visits: evidence on corporate cash holdings

ABSTRACT This study examines the impact of institutional investors’ site visits (SVs) on corporate cash holdings by using a unique dataset of SVs in China during the period of 2012–2019. We find that SVs significantly increase the level of cash holdings, and the result remains robust after addressing endogeneity concerns and selection bias. The positive impact of SVs on cash holding is more pronounced if a firm has a lower information quality, confirming that SVs facilitate information distribution between managers and investors and thus allowing more cash holding. Further analyses show that firms rely greatly on equity issues and internal cash flows for cash savings, and SVs increase the value of cash for shareholders. Collectively, our findings suggest a new effect of institutional investors’ site visits.
Epidemiology of atlas fractures in the United States: A 20-year analysis

Introduction: Fractures of the atlas represent a large portion of cervical spine trauma in the geriatric population. With an aging and more active population, it is expected that the number of patients sustaining atlas fractures is increasing. However, epidemiologic data regarding the incidence of atlas fractures in large populations are scarce. The aim of this study was to investigate the incidence and demographic characteristics of patients with fractures of the atlas in the United States (US) over the last 20 years. Materials and Methods: This descriptive epidemiology study retrospectively analyzed the National Electronic Injury Surveillance System database to identify cases of atlas fractures presenting to US Emergency Departments (EDs) from 2001 to 2020. Annual and overall numbers of fractures and fracture incidence rates, patient demographics (age, gender, race), and injury characteristics (mechanism, associated injuries) were analyzed. Incidence rates are expressed as the number of fractures per million at-risk person-years. Patients were split into four different age groups for comparisons (<18, 18–64, 65–79, 80+ years). Results: An estimated 38,092 cases of acute atlas fractures were identified, representing 11.1% of all cervical fractures and corresponding to an overall incidence rate of 6.2. Slightly more than half (54%) occurred in females and the mean age was 71 years. Overall, a majority (64%) of cases occurred in patients > 70 years old. There was substantial increase in incidence rate with age (<18 years: 0.7; 18–64 years: 2.6; 65–79 years: 17.1; 80 + years: 71.8). The most common injury mechanism was a low-energy fall (74%). Overall, only 42% of atlas fractures were isolated injuries, with 58% of patients sustaining at least one concomitant injury and 48% sustaining at least one additional fracture. Accounting for population growth yielded a significantly increasing incidence over the study period from 1.7 in 2001 to 13.4 in 2020 (annual percent increase = 11, P < 0.00001). Disproportionately large increases in incidence rates were observed in the oldest patient groups. Conclusions: Atlas fractures occur in older patients and are often associated with concomitant injuries to the head and spine. These types of fractures are increasing in the US, especially among the elderly. The annual incidence increased nearly 700% over the course of the study period and in 2020 was over 13 per million overall. In elderly patients >80 years old, the most recent annual incidence rate was over 157 per million.
Birefringence of Thin Uniaxial Polymer Films Estimated Using the Light Polarization Ellipse

A simple method for determining the linear birefringence of the thin layers based on the determination of the orientation of the polarization ellipse of totally polarized light is proposed and it is applied to PVA thin foils. Theoretical notions and the experimental procedure are described. The linear birefringence of polymer thin foils with different degrees of stretching is determined and the applicability of the method is discussed.
