Liberal versus conservative distrust: A construal-level approach to dissimilarity in the workplace.

The dramatic rise in political polarization and aggravation of race relations are prominent in the United States. While dissimilarity to others is thought to undermine trust, I challenge the assumption that dissimilarity does so uniformly in the workplace where cross-party and cross-race interactions are structurally induced. Leveraging construal-level theory, I theorize that deep- versus surface-level differences with a coworker interact with ideology to activate higher versus lower construals of trustworthiness, prompting liberals and conservatives to distrust their coworkers in different ways. For liberals, I argue that perceived political dissimilarity undermines perceived person trustworthiness (a higher level/abstract construal, capturing one's trustworthiness generally as a person in the world) and disclosure. For conservatives, I argue that perceived racial dissimilarity undermines perceived role trustworthiness (a lower level/concrete construal, capturing one's trustworthiness specifically in their job) and reliance. Study 1 (a proof of concept) and Study 2 (a longitudinal, dyadic field study) utilize inductive theory-building and exploratory analyses. Studies 3a, 3b(i), and 3b(ii) (three preregistered experiments) support my hypotheses: Liberals tend to view politically dissimilar coworkers as less trustworthy people in the world and refrain from disclosures, while conservatives tend to view racial outgroup coworkers as less trustworthy in their jobs and refrain from reliance. Given liberal and conservative employees' roles in the calcification of political and racial group cleavages, respectively, organizations must determine whether both forms of bias should be addressed-indeed, racial bias is socially unacceptable, whereas political bias is widely tolerated-and, if so, whether interventions should target employees based on ideology.

A Model to Explore how Communal Traits Affects Stay Intent Amongst Taiwanese Nurses.

AimsThis study discusses the model built to explore low levels of communal traits’ influence on nurses’ stay intent.BackgroundThe high turnover rate and low stay intent amongst Taiwan's nurses is a serious issue. One reason for the low stay intent is nurse-to-nurse interpersonal conflict. Surface-level difference, such as low levels of communal traits, may be an important antecedent factor. Previous studies have found that this type of conflict can frequently arise in female-to-female relationships.DesignThis was quantitative, cross-sectional research using a questionnaire survey.Method249 registered nurses participated in the survey, which employed convenience sampling. The data was collected from January 10th 2020 to February 10th 2020. Results/Findings: We found that nurses with low levels of communal traits become frustrated, creating psychological need thwarting and decreasing stay intention. Belonging perception appears to weaken this. In addition, autonomy and relatedness of need thwarting but not competence mediates the relationship between frustration experience and stay intent. Unlike in past studies, this was not found to be an exclusively female phenomenon.ConclusionImproving belonging perception may be the answer to overcoming negative outcomes caused by surface-level difference in the nursing profession. However, why surface-level difference has a negative influence remains a question that needs to be further explored. In addition, Taiwanese nursing managers in this low status and relationship-oriented nursing culture should also focus on improving frontline nurses’ confidence and self-conceptualizations.

Using semantics to scale up evidence-based chemical risk-assessments.

BackgroundThe manual processes used for risk assessments are not scaling to the amount of data available. Although automated approaches appear promising, they must be transparent in a public policy setting.ObjectiveOur goal is to create an automated approach that moves beyond retrieval to the extraction step of the information synthesis process, where evidence is characterized as supporting, refuting, or neutral with respect to a given outcome.MethodsWe combine knowledge resources and natural language processing to resolve coordinated ellipses and thus avoid surface level differences between concepts in an ontology and outcomes in an abstract. As with a systematic review, the search criterion, and inclusion and exclusion criterion are explicit.ResultsThe system scales to 482K abstracts on 27 chemicals. Results for three endpoints that are critical for cancer risk assessments show that refuting evidence (where the outcome decreased) was higher for cell proliferation (45.9%), and general cell changes (37.7%) than for cell death (25.0%). Moreover, cell death was the only end point where supporting claims were the majority (61.3%). If the number of abstracts that measure an outcome was used as a proxy for association there would be a stronger association with cell proliferation than cell death (20/27 chemicals). However, if the amount of supporting evidence was used (where the outcome increased) the conclusion would change for 21/27 chemicals (20 from proliferation to death and 1 from death to proliferation).ConclusionsWe provide decision makers with a visual representation of supporting, neutral, and refuting evidence whilst maintaining the reproducibility and transparency needed for public policy. Our findings show that results from the retrieval step where the number of abstracts that measure an outcome are reported can be misleading if not accompanied with results from the extraction step where the directionality of the outcome is established.

Hydrothermal synthesis of WO3 film on rough surface to analyze methanol gas at room temperature

In this paper, we synthesized WO3 thick films on a rough and smooth glass substrate by hydrothermal method and then heated to a temperature of 400-degree Celcius. Characteristic techniques such as XRD and SEM analysis were sequenced to determine the crystallite size and grain composition of the finished samples, respectively. We have discussed the results of the Rietveld refinement made using MAUD to determine useful information regarding the atomic sites, mesh parameters, and micro-stresses in the sample. Subsequently, FTIR analysis has been performed to note the critical bond vibrations associated with the material. AFM studies have also been included to determine the pore sizes and understand the surface-level differences between WO3 films on rough and smooth substrates. The room temperature gas sensing mechanism was then discussed in the presence of humidity with methanol, ethanol, and benzene along with most of the targeted gases with different selective parameters at atmospheric pressure. We have tried to develop a theory incorporating the anomalous observation for the methanol gas sensing experiment and explained the future scope of this work.

Analysis of Printed Circuit Boards strains using finite element analysis and digital image correlation

This paper investigates the use of digital image correlation (DIC) and finite element analysis for strain measurement on Printed Board Circuits (PCBs). Circuit boards (PCBs) are designed to mechanically support and electrically connect an electronic component assembly. Due to screw assemblies, the surface level differences on which the PCB is placed, the process of assembling the electronic components induces a certain state of stress and deformation in the PCB. The main components affected are microprocessors due to the way they are glued to PCBs with BGA - Ball grid arrays (BGA). Digital Image Correlation (DIC) is a full-field contactless optical method for measuring displacements and strain in experimental testing, based on the correlation of images taken during test. The experimental setup is realized with Dantec Q-400 system used for image capture and Istra 4D software for image correlations and data analyses. The maximum level of the obtained strain is compared with the allowable limit. Finite element analysis (FEA) is a numerical method of analysis for stresses and strain in structures of any given geometry.

Moving past sporadic eruptions, discursive killing, and running amok: recognizing the convergence of the serial and spree killer

PurposeRapid sequence homicide offenders (RSHOs), formerly spree killers, are an understudied population due to the confusion surrounding their classification in relation to serial murderers. The paper aims to discuss this issue.Design/methodology/approachAn exploratory, comparative analysis of 56 RSHOs and 60 serial murderers was conducted on US-based data from 2014 to 2018 derived from the Consolidated Serial Homicide Offender Database to determine similarities and differences between the cohorts.FindingsRSHOs and serial murderers are similar in that they often kill their victims using a singular method, have limited mobility, kill a similar number of victims both known and unknown to them and are both supremely motivated by domestic anger. There is an inverse relationship between serial murderers and RSHOs: as one group increases in prevalence the other decreases.Practical implicationsIn order to divert men into more pro-social activities, attention must be dedicated to increasing mental health services that provide them with the tools to diffuse their hatred and couple that with effective gun control strategies and ways to enhance the compromised anger management skills of a generation of volatile men.Originality/valueAcademicians have been hesitant to juxtapose these offenders but based this conclusion on surface-level differences. A reimagining of these categorical structures is needed. The once clear delineation between these cohorts may continue to shrink and synchronize until one subsumes the other.

Faultlines as the “Earth’s Crust”: The Role of Team Identification, Communication Climate, and Subjective Perceptions of Subgroups for Global Team Satisfaction and Innovation

Distributed teams in organizations are ubiquitous, use digital technologies extensively, and have the potential to be innovative due to the level of diversity of their members, but they face many challenges. Demographic differences can often result in the activation of team faultlines (overlap of surface-level differences), leading to formation of subgroups and negative impacts on group outcomes. This study examines the relationships between faultlines and their outcomes to discover how certain team processes mitigate the negative effects of dormant faultlines on team outcomes in globally distributed teams. The analysis of a survey of 165 global team members representing 27 teams in a multinational high-tech organization demonstrated that psychologically safe communication climate (PSCC) and team identification moderated the relationship between faultlines and perceived subgroups. Specifically, in teams with low PSCC and identification, dormant faultlines predicted an increase in perception of subgroups. The findings also indicate that perceived subgroups moderate the relationship between dormant faultlines and team satisfaction. When subgroups are less perceived by team members, faultlines predict an increase in satisfaction.

WHAT SINAMA LANGUAGE IS THIS? LANGUAGE FEATURES AND SIMPLE METHODS TO HELP THE NON-LINGUIST NAVIGATE THE SINAMA LANGUAGES AND DIALECTS

The Sama have proven over and over again difficult to classify. Non-Sama have called them Badjaw, Samal, and Siyamal. Some Sama have refused to identify with the name Sama and call themselves only by the name of their places of origin. Others have found benefit to identify with the names given them by outsiders. Others have blended in with the Tausug people. As the Sama people have spread across the Philippines and Malaysia, Sama groups may experience reduced contact with other once neighboring or intermingled Sama groups. This paper gives practical though imperfect litmus test examinations that are of use to a cultural observer or those of Sama heritage in identifying which language and dialect of Sinama a conversant or text is written in. The paper focuses on giving meaning to four Sama-Badjaw language classifications and identifying surface level differences that exist among these languages as well as helping to pinpoint various dialects and under which language classification they fit best. The four languages are Northern, Central, Western, and Southern Sinama. Differences in vowel sounds, pronoun usage, language affixation and vocabulary are used to identify language category as well as give insight into what dialect of a language is being spoken. The paper is intentionally abbreviated and simplified in order to make it possible for non-linguists and even those with very simple knowledge of Sinama to make use of its findings. Keywords: Sama, Sinama languages, Sinama dialects

Experimental determination of strain distribution on Printed Circuit Boards using Digital image correlation

The paper investigates the use of digital image correlation (DIC) for strain measurement on Printed Board Circuits (PCBs). Digital Image Correlation (DIC) is a full-field contactless optical method for measuring displacements and strain in experimental testing, based on the correlation of the digital images taken during test. This method is used to measure strain of the surfaces of materials and structures subjected to various stresses (such as mechanical stresses or thermal stresses).So, this method is used according to the documentation for a variety of applications such as: large deformation measurements, crack analysis, stress strain curves (σ-ε) for new materials, constructions - to evaluate certain displacements and cracks, measurement of strain caused by temperature variations.Circuit boards (PCBs) are designed to mechanically support and electrically connect an electronic component assembly. Due to screw assemblies, the surface level differences on which the PCB is placed, the process of assembling the electronic components induces a certain state of stress and deformation in the PCB. The main components affected are microprocessors due to the way they are glued to PCBs with BGA - Ball grid arrays (BGA).To determine the strain on PCBs, the actual measurement method uses strain gages. This method allows determining the strain only at certain points. The Digital Image Correlation method provides full field strain field. The experimental setup is realized with Dantec Q-400 system used for image capture and Istra 4D software for image correlations and data analyses. The maximum level of the obtained strain is compared with the allowable limit.

Evaluating ontology coverage and internal structure to better align patients with clinical trials

ABSTRACTRecruiting patients for a clinical trial is a time‐consuming activity that can delay recruiting and the reporting of clinical trial results. Ontologies can be used to align the inclusion criteria of a clinical trial with candidate patients but such an approach requires that (a) the concepts within an ontology adequately cover patient characteristics that are likely to be used in a clinical trial; (b) the quantitative similarity scores decline gracefully patient characteristics become less suited to the trial protocol; and (c) the alignment must be robust despite surface level differences in how eligibility features are described. The concepts are extracted from grant proposals and eight archetype breast cancer patients are mapped as matching a breast cancer clinical trial protocol does. The Medical Subject Heading (MeSH) and National Cancer Institute Thesaurus (NCIt) are evaluated with respect to coverage, connectivity, standard similarity properties and the granularity of rankings.

Combining the Stock Unearthing Method and Structure-from-Motion Photogrammetry for a Gapless Estimation of Soil Mobilisation in Vineyards

In vineyards, especially on steep slopes like the Ruwer-Mosel Valley, Germany, soil erosion is a well-known environmental problem. Unfortunately, some enterprises and farmers are not aware of how much soil is being lost and the long-term negative impacts of soil erosion. The non-invasive technique of the stock unearthing method (SUM) can be used for a quick assessment of soil erosion in vineyards. SUM uses the graft union as a reference elevation for soil surface changes since the time of plantation commencement, which is modelled with the help of a geographic information system. A shortcoming of SUM is that the areas between the pair-vine cross sections are not surveyed, hence it is not accurate enough to identify erosion hot-spots. A structure-from-motion (SfM) photogrammetric technique is adopted to complement SUM to fill this data gap. Combining SUM (only measuring the graft unions) and SfM techniques could lead to an improved, easy and low-cost method with a higher accuracy for estimation of soil erosion based on interpolation by projection, and contact and gapless measuring. Thus, the main aim of this paper was to map the current soil surface level and to improve the accuracy of estimation of long-term soil mobilisation rates in vineyards. To achieve this goal, the TEPHOS (TErrestrial PHOtogrammetric Scanner), a static five camera array, was developed on a 20 m2 plot located in a steeply sloping vineyard of the Ruwer-Mosel Valley, Trier, Germany. A total soil mobilisation of 0.52 m3 (9.14 Mg ha yr−1) with soil surface level differences in excess of 30 cm in the 40 years since plantation commencement were recorded. Further research is, however, needed to reduce the number of photos used for the point cloud without loss of accuracy. This method can be useful for the observation of the impacts of other factors in vineyards, such as tillage erosion, runoff pathway detection or the trampling effect on soil erosion in vineyards.

Stem cell-like populations and immunoregulatory molecules in periodontal granulation tissue.

Determine the presence of mesenchymal stem cells (MSCs) in healthy periodontal tissue and periodontal granulation tissue (GT) and explore associations between immuno-regulatory molecules and selected subgingival microorganisms. Mesenchymal stem cells were isolated, propagated and characterised by flow cytometry from a region of healthy gingival tissue and inflamed GT of 10 systemically healthy non-smokers with chronic periodontitis. Tissue levels of immunoregulatory molecules were determined by qPCR and Gingival Crevicular Fluid (GCF) levels by ELISA. Subgingival plaque levels of periodontal pathogens were determined by qPCR RESULTS: Cells with MSC-properties were isolated from both inflamed GT and healthy gingival (G) tissue. A pro-inflammatory process predominated in GT which was partly reflected in GCF and putative periodontal pathogens were higher at diseased sites. However, there was no significant difference in surface levels of mesenchymal (CD90, CD73, CD146, CD271, STRO-1), endothelial (CD105, CD106), hematopoietic (CD34, CD45) and embryonic (SSEA-4) stem cell markers between MSCs isolated from GT and G tissue. Periodontal lesions, albeit inflamed, retain healing potential as inferred by the presence of MSC-like cells with similar immunophenotypic characteristics to those found in healthy periodontal tissue. Therefore, there might be merits for healing in preserving sufficient GT in-situ during periodontal surgery.

Hybrid passive control system of TLD and TMD for seismic response mitigation of Tall Buildings

Using Tuned liquid damper is one of the passive control methods in structures. The system consists of some water tanks that are installed at the highest level of structure. The water turbulence created inside them is used to reduce the seismic oscillation of structure. Therefore, the damper characteristics (tank size and depth of water in it) should be selected in such a way that the frequency of water in the reservoir is tuned with the frequency of structural vibrations. The controlling force to reduce the structural vibrations is created by the pressure difference caused by the difference in surface levels of the liquid in the end chambers which acts as a shear force at the bottom of tanks. It is required to obtain the water surface level at different times to calculate the controlling force caused by tuned liquid dampers. In the present study, the parameters of damper have been simultaneously minimized by Genetic Algorithm (GA) method and based on single-purpose function (displacement of the top story) and multi-purpose functions (displacement and acceleration of the top story). Optimal Pareto Front objective functions are utilized to achieve optimal responses. A 20-story building has been investigated as a numerical example to carry out this study. In this study the comparisons between TLD system and TMD system, i.e. integrated TLD-TMD system is made with the application of Genetic Algorithms. The author codes all the numerical solutions and Genetic Algorithm program.

Modeling of Wind Effects on Stratified Flows in Open Channels: A Model for the Istanbul Strait (Bosphorus)

Stratified flows in open channels arise as a result of density or surface level differences. If the channel is connected to a basin at one or both ends, strong winds originating from the basin cause the “wind setup” effect that increases the water level at the entrance of the channel. On the other hand, along the channel, persistent winds in the upper layer flow direction lead to an increase of the drift velocity and to a decrease in upper layer flow depth. The Istanbul Strait (Bosphorus) connecting the Black and the Marmara Seas, is characterized by a stratified flow caused by the surface level and salinity difference between these basins, consisting of a southward upper layer flow and a northward lower layer flow. Along the strait, there are three hydraulic control points; the north sill, a midway contraction reach and the south sill. Under wind effects, the northern and southern entrances of the strait behave as an estuary whereas the midway reach to the south of the contraction acts as as an open channel. In winter, when the sea level difference is relatively low, the wind setup due to southerly winds may cause a blockage and even reversal of the upper layer flow. On the other hand in spring when there is excessive river discharge, northerly winds increase the influx of Black Sea waters into the strait and may lead to a blockage of the lower layer. We claim that strong northerly winds may cause a decrease of the upper layer depth beyond the contraction and we propose a simple model for its estimation in terms of the wind and water flow speeds.

How sensory-motor systems impact the neural organization for language: direct contrasts between spoken and signed language.

To investigate the impact of sensory-motor systems on the neural organization for language, we conducted an H215O-PET study of sign and spoken word production (picture-naming) and an fMRI study of sign and audio-visual spoken language comprehension (detection of a semantically anomalous sentence) with hearing bilinguals who are native users of American Sign Language (ASL) and English. Directly contrasting speech and sign production revealed greater activation in bilateral parietal cortex for signing, while speaking resulted in greater activation in bilateral superior temporal cortex (STC) and right frontal cortex, likely reflecting auditory feedback control. Surprisingly, the language production contrast revealed a relative increase in activation in bilateral occipital cortex for speaking. We speculate that greater activation in visual cortex for speaking may actually reflect cortical attenuation when signing, which functions to distinguish self-produced from externally generated visual input. Directly contrasting speech and sign comprehension revealed greater activation in bilateral STC for speech and greater activation in bilateral occipital-temporal cortex for sign. Sign comprehension, like sign production, engaged bilateral parietal cortex to a greater extent than spoken language. We hypothesize that posterior parietal activation in part reflects processing related to spatial classifier constructions in ASL and that anterior parietal activation may reflect covert imitation that functions as a predictive model during sign comprehension. The conjunction analysis for comprehension revealed that both speech and sign bilaterally engaged the inferior frontal gyrus (with more extensive activation on the left) and the superior temporal sulcus, suggesting an invariant bilateral perisylvian language system. We conclude that surface level differences between sign and spoken languages should not be dismissed and are critical for understanding the neurobiology of language.

Experimental Investigation on the Effect of Container Geometry Change to Liquid Sloshing

Liquid sloshing is any motion of free liquid surface inside its container. Sloshing may generate hydrodynamics loads that can be dangerous to structural integrity and stability of moving container. In this study, liquid sloshing in cubical and cylindrical containers with similar characteristic length were investigated. The containers with liquid inside were excited sinusoidally by using an electrodynamics shaker while the free liquid surface level change was captured by using high speed camera. The highest free liquid surface level difference obtained for cylindrical and cubical containers were compared. Results show that cylindrical containers produce less liquid sloshing and thus more suitable to be used for liquid transportation.

Decision Making in the Reward and Punishment Variants of the Iowa Gambling Task: Evidence of “Foresight” or “Framing”?

Surface-level differences in the reward and punishment variants, specifically greater long-term decision making in the punishment variant of the Iowa Gambling Task (IGT) observed in previous studies led to the present comparison of long-term decision making in the two IGT variants (n = 320, male = 160). It was contended that risk aversion triggered by a positive frame of the reward variant and risk seeking triggered by a negative frame of the punishment variant appears as long-term decision making in the two IGT variants. Apart from the frame of the variant as a within-subjects factor (variant type: reward and punishment), the order in which the frame was triggered (order type: reward–punishment or punishment–reward), and the four types of instructions that delineated motivation toward reward from that of punishment (reward, punishment, reward and punishment, and no-hint) were hypothesized to have an effect on foresighted decision making in the IGT. As expected, long-term decision making differed across the two IGT variants suggesting that the frame of the variant has an effect on long-term decision making in the IGT (p < 0.001). The order in which a variant was presented, and the type of the instructions that were used both had an effect on long-term decision making in the two IGT variants (p < 0.05). A post hoc test suggested that the instructions that differentiated between reward and punishment resulted in greater foresight than the commonly used IGT instructions that fail to distinguish between reward and punishment. As observed in previous studies, there were more number of participants (60%) who showed greater foresight in the punishment variant than in the reward variant (p < 0.001). The results suggest that foresight in IGT decision making is sensitive to reward and punishment frame in an asymmetric manner, an observation that is aligned with the behavioral decision making framework. Benefits of integrating findings from behavioral studies in decision neuroscience are discussed, and a need to investigate cultural differences in the IGT studies is pointed out.

Understanding the effects of substantive responses on trust following a transgression

Four experiments were conducted to investigate the implications of ‘substantive’ responses for the repair of trust following a violation and the cognitive processes that govern how and when they are effective. These studies examined two forms of substantive responses, penance and regulation, that represent different categories of trust repair attempts. The findings from Studies 1–3 suggest that both can be effective to the extent that they elicit the crucial mediating cognition of perceived repentance. Data from Study 2 revealed that trustors saw signals of repentance as more informative when the transgression was due to a lapse of competence than due to a lapse of integrity. Study 4 compared these substantive responses to apologies (a non-substantive response) and revealed that, despite their surface-level differences, they each repaired trust through ‘perceived repentance.’ The paper offers an integrative framework for understanding the relationships among a range of trustor responses.
