The impact of relational demography and communication apprehension on follower perceptions of leader–follower relationships in the hospitality industry

The paper aims to clarify the multivariate effects of follower communication apprehension (CA) and demographic dissimilarity on follower perceptions of the leader–follower relationship quality (i.e. measured by leader–member exchange (LMX) theory). This study examined the possible mediating effects of follower CA on the relationship between demographic dissimilarity and LMX. ,Research was collected from self-report ratings of one member of the dyad; several proactive techniques were utilized to reduce common method variance in the development and administration of the survey instrument. In total, 260 (N = 260) full-time hospitality industry employees participated in the study. ,The results of this study indicate demographic dissimilarity has minimal effect on LMX and CA. However, the results indicated that follower CA was negatively related to follower perceptions of LMX quality. In addition, the results indicated that tenure working with the supervisor was negatively related to follower CA and positively related to follower perceptions of LMX quality. ,Research results may lack generalizability, and causality cannot be confirmed. Future studies utilizing longitudinal designs and/or data collected from each member of the dyad may provide support for current findings. ,This paper includes implications for understanding how situational characteristics influence follower CA and perceptions of LMX to encourage supervisors to increase communication with new subordinates, especially during the organizational acculturation process, thus reducing turnover. Furthermore, the significant relationship between age dissimilarity and CA offers practical implications for managing and celebrating generational differences in the workplace and bridging the gap between generations by maximizing communication between supervisors and subordinates. Communication is an essential consideration in the hospitality industry linked to creativity, relationship building and enhanced service experiences. Ultimately, this paper provides guidance for leaders to build sustainable, positive relationships with subordinates through more effective communication and build more inclusive service-based organizations. ,This paper contributes to communication and leadership management practices by addressing four major problems: (1) limited research on situational characteristics that inhibit LMX quality, (2) limited research on communication variables as antecedents to LMX, (3) minimal research on the relationship between CA and LMX and (4) non-existent research on CA as a mediating variable in the relationship between demographic dissimilarity and LMX.
Reproductive Factors and Breast Cancer Prognosis: The Possible Role of Cesarean Delivery

Objective: To evaluate the possible associations between tumor pathological characteristics and reproductive factors in women with breast cancer, including method of child delivery. Materials and Methods: Patients diagnosed as breast cancer between January 2012 and April 2013 in Ankara University Hospitals who had at least one full term pregnancy were included. Data upon pathological prognostic features of tumors and reproductive history of patients were obtained from patient files. Results: 434 patients with breast cancer were included. Mean age at the time of breast cancer diagnosis was 49.2±10.7 years. History of at least one cesarean delivery was present in 17% of the patients (n=75). Axillary lymph node positivity was related to younger age at first full-term pregnancy (p=0.018), and higher number of parities (p=0.001) in estrogen receptor positive (ER+) breast cancer patients. Although extracapsular invasion was related to shorter time interval since last parity to cancer diagnosis in the whole population (p=0.029), this association disappeared when patients were categorized according to ER status. However, in ER+ patients, history of cesarean delivery was associated with extracapsular invasion (p=0.023). Also, our findings indicated that patients with history of cesarean delivery were diagnosed with breast cancer at younger ages, and after a shorter time interval since last parity (p<0.001). Tumor size (p=0.001), grade (p=0.046), axillary lymph node positivity (p=0.001), lymphovascular invasion (p<0.001), and shorter duration of time since last parity to breast cancer diagnosis (p=0.029) were indicators of metastatic disease. Conclusion: Our findings indicate that history of cesarean delivery may be associated with poor prognosis in ER+ patients with breast cancer.
The Environmental Impact of Ecological Intensification in Soybean Cropping Systems in the U.S. Upper Midwest

Introducing cover crops is a form of ecological intensification that can potentially reduce local, regional and global environmental impacts of soybean cropping systems. An assessment of multiple environmental impacts (global warming potential, eutrophication, soil erosion and soil organic carbon variation) was performed on a continuous soybean system in the U.S. upper Midwest. Four sequences were assessed and compared: a soybean cropping system with winter camelina, field pennycress, or winter rye as cover crop, plus a control (sole soybean). Cover crops were interseeded into standing soybean in Year 1, while in Year 2 soybean was relay-cropped into standing camelina or pennycress. Rye was terminated before sowing soybean. When compared with the control, sequences with cover crops showed lower eutrophication potential (4–9% reduction) and soil erosion (5–32% reduction) per ha year−1, in addition to a lower global warming potential (3–8% reduction) when the cover crop was not fertilized. However, when the economic component was included in the assessment, and the results expressed per USD net margin, the sequences with cover crops significantly reduced their performance in all categories of impact considered. A further optimization of field management for camelina and pennycress is recommended to make the cropping system more sustainable.
Organizational Politics and Job Satisfaction: Mediation and Moderation of Political Skills

The research examined the impact of moderation and mediation of political skill on organizational politics and job satisfaction. It applied a quantitative method. The population was 240 employees from the middle to top management in local government offices. With purposive sampling, 86 respondents working in the Regional Government Work Unit of Ternate City were involved in the survey. The research used a hierarchical regression analysis as a statistical analysis and IBM SPSS statistics Version 24. The results show that political skill strengthens the relationship between organizational politics and job satisfaction. Then, political skill also fully mediates the relationship between organizational politics and job satisfaction.
Projections of river floods in Europe using EURO‐CORDEX, CMIP5 and CMIP6 simulations

A large ensemble of hydroclimatic simulations is used to simulate the occurrence of river floods over Europe in a climate change context. A river routing model derived from a distributed hydrological model (CHyM) is forced with 44 EURO‐CORDEX, 13 CMIP5 and 7 CMIP6 simulations to assess the effects of climate change on the flood magnitude under two different scenarios. The impact of climate change is evaluated using a 100‐year return period discharge indicator (Q100). Results show a decrease in magnitude of Q100 flood events over the Mediterranean, Scandinavia and north eastern Europe. This latter signal appears particularly robust and in contrast to the projected mean flow signal, which is shown to increase by the end of the century in response to increased mean precipitation. The reduction of snow accumulation during winter induced by a large increase of late winter temperatures is the main reason behind the decrease of floods over the North Eastern regions. An opposite signal is projected over Great Britain, Ireland, Northern Italy and Western Europe, where a robust signal of flood magnitude increase is evident, being driven by an increase of extreme precipitation events. All these simulations are intended for use in impact assessment studies towards the development of suitable response options.
Enhancement of Multimodal Traffic Safety in High-Quality Transit Areas

C S U T R A N S P O R T A T I O N C O N S O R T I U M Walking and cycling provide immense health and environmental benefits. However, pedestrians and bicyclists are highly vulnerableon roadways. While numerous studies consider infrastructure facilities such as intersections, sidewalks, and bike lanes, there is a lack of sufficient research devoted to safety analysis regarding traffic accidents surrounding transit stations. Transit stations, which serve as the important modal interface for pedestrians and bicyclists, must be examined to improve safety.
Adaptive-Hybrid Harmony Search Algorithm for Multi-Constrained Optimum Eco-Design of Reinforced Concrete Retaining Walls

In the optimum design of reinforced concrete (RC) structural members, the robustness of the employed method is important as well as solving the optimization problem. In some cases where the algorithm parameters are defined as non-effective values, local-optimum solutions may prevail over the existing global optimum results. Any metaheuristic algorithm can be effective to solve the optimization problem but must give the same results for several runs. Due to the randomization nature of these algorithms, the performance may vary with respect to time. The essential and novel work done in this study is the comparative investigation of 10 different metaheuristic algorithms and two modifications of harmony search (HS) algorithm on the optimum cost design of RC retaining walls constrained with geotechnical and structural state limits. The employed algorithms include classical ones (genetic algorithm (GA), differential evaluation (DE), and particle swarm optimization (PSO)), proved ones on structural engineering applications (harmony search, artificial bee colony, firefly algorithm), and recent algorithms (teaching–learning-based optimization (TLBO), flower pollination algorithm (FPA), grey wolf optimization, Jaya algorithm (JA)). The modifications of HS include adaptive HS (AHS) concerning the automatic change of algorithm parameters and hybridization of AHS with JA that is developed for the investigated problem. According to the numerical investigations, recent algorithms such as TLBO, FPA, and JA are generally the best at finding the optimum values with less deviation than the others. The adaptive-hybrid HS proposed in this study is also competitive with these algorithms, while it can reach the best solution by using a lower population number which can lead to timesaving in the optimization process. By the minimization of material used in construction via best optimization, sustainable structures that support multiple types of constraints are provided.
Reverse Engineering in Accounting-Based Equity Valuation Part I: A Fundamentalist Perspective and a New Model Approach

This paper serves as the first in a two-part discussion on existing applications and empirical study of reverse engineering (RE) in accounting-based equity valuation from the perspective of a fundamental investor. Despite a history of over 80 years, the literature on RE shows a no clear consensus on the modeling, conceptualization and operationalization of the technique. In the first part, we derive a new assessment framework for applied RE in accounting-based equity valuation from the perspective of a fundamental investor. Based on the framework, we find that there is no approach to reverse engineering that sufficiently fulfils the needs of fundamental investors in the literature. In search for a remedy, we derive a model based on the Ohlson (1995) model that is tailored to reverse engineering and complements a more extensive fundamental analysis. The second part applies the theoretical framework to stock screening based on fundamentals and market expectations, focusing on characteristics of quality and cheapness. That said, the two parts of the series belong together and we recommend them to be regarded accordingly.
Recreational Drug use and Risk of HIV Infection Among Young Men Who Have Sex with men: A Cross-Sectional Study in Tianjin, China

Background- Recreational drug use among young men who have sex with men (YMSM) was a public health issue of worldwide concern. Evidence had shown the relevance between recreational drug use and human immunodeficiency virus (HIV) infection. This study aimed to investigate the current prevalence state of recreational drug use among YMSM in Tianjin, discern the characteristics of YMSM who used recreational drugs or not and examine the interaction effect of recreational drug use and unprotected anal intercourse (UAI) on HIV infection.Methods- In 2018, a cross-sectional study was conducted in Tianjin, China. The snowball sampling method was used to recruit YMSM. Participants were recruited from gay bars, gay bathhouses, social network sites (WeChat, QQ, gay chat website), gay apps and peer referrals. Structured questionnaires were used to collect data.Results- A total of 1075 YMSM met the eligibility criteria and were included in the study eventually. The overall HIV prevalence was 4.3% (46/1075). Of all the recreational drugs involved in this study (rush poppers, methamphetamine, capsule No.0), rush poppers (406/517,78.5%) were the most popular among YMSM in Tianjin. Compared with non-drug users, drug users were more likely to have first sex earlier, be bisexual, be male sex worker (MSW), have a higher education level, seek sex partners through physical venues, engage in UAI, have sexually transmitted infection (STI), and receive HIV testing. Moreover, recreational drug use and UAI were associated with the increased risk of HIV infection [adjusted OR:3.6 (95%CI: 1.7-7.6) and 4.9 (95%CI: 2.2-10.4), respectively]. There was additive interaction of recreational drug use and UAI on HIV infection [relative excess risk due to interaction (RERI): 6.949 (95%CI: 0.011‐13.887); attributable proportion due to interaction (AP): 0.809 (95%CI: 0.578‐1.039)]. Conclusions- Recreational drug use was common and correlated with HIV infection among YMSM in Tianjin. There was an urgent need to build novel targeted HIV prevention strategies to discern and reduce recreational drug use among YMSM in China.
Consonance Preferences Within an Unconventional Tuning System

Recently, Bowling, Purves, and Gill (2018a), found that individuals perceive chords with spectra resembling a harmonic series as more consonant. This is consistent with their vocal similarity hypothesis (VSH), the notion that the experience of consonance is based on an evolved preference for sounds that resemble human vocalizations. To rule out confounding between harmonicity and familiarity, we extended Bowling et al.’s (2018a) procedure to chords from the unconventional Bohlen-Pierce chromatic just (BPCJ) scale. We also assessed whether the association between harmonicity and consonance was moderated by timbre by presenting chords generated from either piano or clarinet samples. Results failed to straightforwardly replicate this association; however, evidence of a positive correlation between harmonicity and consonance did emerge across timbres following post hoc exclusion of chords containing intervals that were particularly similar to conventional equal-tempered dyads. Supplementary regression analyses using a more comprehensive measure of harmonicity confirmed its positive association with consonance ratings of BPCJ chords, yet also showed that spectral interference independently contributed to these ratings. In sum, our results are consistent with the VSH; however, they also suggest that a composite model, incorporating both harmonicity as well as spectral interference as predictors, would best account for variance in consonance judgments.
Emotion work as a source of employee well- and ill-being: the moderating role of service interaction type

ABSTRACT This study presents a framework for classifying service occupations based on the type of interaction between employees and customers to clarify the mixed relationships between emotion work and well-being. Drawing on the challenge-hindrance stressor literature, we propose that positive emotion requirements are a challenge stressor for almost all service providers, while negative emotion requirements and emotion-rule dissonance are only challenge stressors in certain service contexts. Data from 33 independent samples comprising 7,075 employees showed that all emotion work variables were positively related to emotional exhaustion. In line with expectations, only positive emotion requirements were consistently and positively linked to personal accomplishment. Service interaction type measured by expert ratings was used to test under what circumstances negative emotion requirements and emotion-rule dissonance are challenge stressors with positive consequences. Results revealed that negative emotion requirements were positively related to personal accomplishment when interactions were highly complex and employees were highly required to identify with customers. When interactions were standardized and of low complexity, when service providers were substitutable, and when there was no need to identify, there were negative relationships. For emotion-rule dissonance, positive relationships emerged when employees engaged in standardized interactions, were substitutable, but needed to identify with customers.
Semi‐Monthly Lunar Tide Oscillation of foF2 in Equatorial Ionization Anomaly (EIA) Crests During 2014–2015 SSW

We investigate the ionospheric responses to the 2014–2015 sudden stratospheric warming (SSW) event in winter and summer hemisphere by using ionosondes distributed in Equatorial Ionization Anomaly (EIA) crests. Daily mean value of foF2 at each station shows obvious semimonthly lunar tide (∼14.5‐day period) modulation from lower to higher latitude in both hemispheres during SSW period. Besides, lunar tide modulation in summer hemisphere is later than that in winter hemisphere, which can be explained by the planetary wave penetrating across the equator from winter to summer hemisphere. In addition, lunar semidiurnal tide extracted from foF2 presents evident enhancement after warming onset. Our results demonstrate the quasi 16‐day periodic oscillations in F region of EIA crests are caused by the enhanced lunar tide in dynamo wind of mesosphere and lower thermosphere region, which is due to the disturbances in the zonal mean wind distribution in connection with SSW.
Statistical Tolerance Analysis of 3D-Printed Non-Assembly Mechanisms in Motion Using Empirical Predictive Models

Fused Deposition Modelling (FDM) enables the fabrication of entire non-assembly mechanisms within a single process step, making previously required assembly steps dispensable. Besides the advantages of FDM, the manufacturing of these mechanisms implies some shortcomings such as comparatively large joint clearances and geometric deviations depending on machine-specific process parameters. The current state-of-the-art concerning statistical tolerance analysis lacks in providing suitable methods for the consideration of these shortcomings, especially for 3D-printed mechanisms. Therefore, this contribution presents a novel methodology for ensuring the functionality of fully functional non-assembly mechanisms in motion by means of a statistical tolerance analysis considering geometric deviations and joint clearance. The process parameters and hence the geometric deviations are considered in terms of empirical predictive models using machine learning (ML) algorithms, which are implemented in the tolerance analysis for an early estimation of tolerances and resulting joint clearances. Missing information concerning the motion behaviour of the clearance affected joints are derived by a multi-body-simulation (MBS). The exemplarily application of the methodology to a planar 8-bar mechanism shows its applicability and benefits. The presented methodology allows evaluation of the design and the chosen process parameters of 3D-printed non-assembly mechanisms through a process-oriented tolerance analysis to fully exploit the potential of Additive Manufacturing (AM) in this field along with its ambition: ‘Print first time right’.
Combined Management can Decrease Blood Pressure: A Health-seeking Behaviors Investigation among Hypertensive Patients in Urban Communities in China

Background: Hypertensive patients can freely choose the informal medical facilities such as pharmacies, community health service centers, and cardiology clinics in secondary or tertiary hospitals, as the routine places for medical treatment in China at present. It is not clear the proportion, influencing factors and the effects on blood pressure (BP) of different health-seeking behaviors among hypertensive patients in urban communities. The aim of the study is to investigate the health-seeking behaviors and the effect on BP of different health-seeking behaviors among hypertensive patients in urban communities in China.Methods: A cross-sectional survey of hypertension was conducted in urban communities in Chengdu. 437 hypertensive patients seeking medical help regularly were sequentially enrolled to fill out the questionnaire on health-seeking behaviors.Results: The average age was 67.1±7.5 years. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 144.2±17.9 mmHg and 75.4±10.4 mmHg, respectively, and the control rate of BP was 41.0%. Among the hypertensive patients investigated, 5.2% of which chose the informal medical facilities, 62.8% chose the community health service center, 21.5% chose the cardiology clinics in secondary or tertiary hospitals, and 10.5% chose both community health service center and cardiology clinics as the usual places for medical treatment. There were statistical differences in education levels, proportions of home BP monitoring, establishing chronic disease archives in community, medication compliance and side effects of drugs among the four groups. The SBP was 150.9 ±19.8, 145.1±18.0, 143.8±17.5 and 136.3±15.1 mmHg (P=0.007) in the four groups respectively and it was significantly lower in the combined management group than in the other three groups. The control rate of BP was 23.8%, 39.4%, 43.0% and 54.8% (P=0.100), respectively. Compared with patients choosing the informal medical facilities, patients in the combined management group had significant higher BP control rate (OR = 3.679, P = 0.035). Conclusions: Combined management with both community health service center and higher-level hospitals can decrease BP.
Modeling and Simulation Techniques Used in High Strain Rate Projectile Impact

A series of computational models and simulations were conducted for determining the dynamic responses of a solid metal projectile impacting a target under a prescribed high strain rate loading scenario in three-dimensional space. The focus of this study was placed on two different modeling techniques within finite element analysis available in the Abaqus software suite. The first analysis technique relied heavily on more traditional Lagrangian analysis methods utilizing a fixed mesh, while still taking advantage of the finite difference integration present under the explicit analysis approach. A symmetry reduced model using the Lagrangian coordinate system was also developed for comparison in physical and computational performance. The second analysis technique relied on a mixed model that still made use of some Lagrangian modeling, but included smoothed particle hydrodynamics techniques as well, which are mesh free. The inclusion of the smoothed particle hydrodynamics was intended to address some of the known issues in Lagrangian analysis under high displacement and deformation. A comparison of the models was first performed against experimental results as a validation of the models, then the models were compared against each other based on closeness to experimentation and computational performance.
