Superior Short Circuit Performance of 1.2kV SiC JBSFETs Compared to 1.2kV SiC MOSFETs

The high-temperature switching performance of a 1.2kV SiC JBSFET is compared with a 1.2kV SiC MOSFET using a clamped inductive load switching circuit representing typical H-bridge inverters. The switching losses of the SiC MOSFET are also evaluated with a SiC JBS Diode connected antiparallel to it. Measurements are made with different high-side and low-side device options across a range of case temperatures. The JBSFET is observed to display a reduction in peak turn-on current – up to 18.9% at 150°C and a significantly lesser turn-on switching loss – up to 46.6% at 150°C, compared to the SiC MOSFET.
Personality Resources and Work Motivation: A Beneficial Synergy

Purpose. The paper aims to show the motivational function of personality resources in the organizational context. Based on the Personality Potential model (Leontiev, 2011) and Self-Determination Theory (SDT), we hypothesized that personality resources facilitate productive motivation and engagement with the work environment, resulting in positive outcomes for the individual, as well as for the organization. We aimed to explore three research questions: 1) whether personality resources positively predict autonomous motivation and negatively predict controlled motivation, 2) whether work motivation mediates the effects of personality resources on well-being outcomes, and 3) whether personality resources and work motivation have synergistic effects on workplace well-being outcomes. Study design. We used data from two samples of employees of a Russian production enterprise using across-sectional design (Study 1, N = 4,708) and a longitudinal design with a two-year interval between measurements (Study 2, N = 372). The participants completed measures of personality resources (hardiness, dispositional optimism, generalized self-efficacy, tolerance for ambiguity), work motivation, and well-being outcomes (life satisfaction, job satisfaction, work-life balance, work engagement, organizational commitment). Findings. A single dimension of personality resources emerged as apositive predictor of autonomous motivation and a negative predictor of controlled motivation, bothin the cross-sectional and in the longitudinal perspective. The change in well-being outcomes was mainly explained by autonomous motivation at Time 1. Using a moderated mediation model, we found that work motivation partially mediated the effects of personality resources on well-being outcomes and exhibited the theoretically predicted interaction effects on work-life balance, job satisfaction, and organizational commitment. Value of the results. The results are in line with the hypothesis about the motivating function of personality resources.
Farm exit, wellbeing and autonomy: a quantitative analysis of exited farmers in Australia

ABSTRACT In many developed countries, the number of farmers working in commercial agriculture continues to decline with more likely to leave in the future. The act of farming and autonomy of farming work are central to farmers’ identity. Although loss of autonomy when exiting farming may pose a threat to identity and reduce farmer wellbeing, these are notable gaps in existing social research. This article retrospectively examines farmer autonomy and wellbeing in a sample of 412 Australian exited farmers. Regression modelling showed those who reported lost autonomy when leaving farming reported consistently lower levels of wellbeing than those who did not lose autonomy. Supports that assist farmers to maintain their autonomy during and after exiting the occupation may help to protect against stresses associated with farm exit and improve wellbeing outcomes for exited farmers.
Developing Sustainable Ultra High Strength Concrete Mixtures Using Spent Foundry Sand

This study presents the development of ultra high strength concrete (UHSC) that has been made more sustainable by using both local materials from central Texas and spent foundry sand (FS) from the metal casting industry, which has also been obtained locally. This study first describes various trial mixtures tested as well as the specimen preparation techniques investigated that led to the final UHSC-FS mixtures. The developed mixtures were proportioned with local constituents to increase the sustainable impact of the material by reducing emissions due to shipping as well as making UHSC more affordable to a wider variety of applications. The final mixture design constituents were: river sand, locally available type I/II cement, silica fume, and spent FS, which was obtained from a local steel casting company. Multiple variables were investigated, such as the aggregate type and size, concrete age (7, 14, and 28-days), the curing regimen, and the water-to-cement ratio (w/cm) to optimize a UHSC mixture that used local materials and FS. This systematic development revealed that heat curing the specimens in a water bath at 50 oC (122 oF) after demolding and then dry curing at 200 oC (392 oF) two days before testing with a w/cm of 0.20 at 28-days produced the highest compressive strengths. Once an optimum UHSC mixture was identified a partial replacement of the fine aggregate with FS was completed at 10%, 20%, and 30%. The results showed an increase of compressive strength performance at 10% replacement, followed by no change at 20%, and finally a slight decrease at 30%. Developing this innovative material with local materials and FS ultimately produces a novel sustainable construction material, reduces the costs, and produces mechanical performance similar to prepackaged, commercially, available construction building materials.
Comparison of Response Scales as Measures of Indoor Environmental Perception in Combined Thermal and Acoustic Conditions

Response scales are widely used to assess the personal experience of sensation and perception in built environments, and have a great impact on the quality of the responses. The purpose of this study was to investigate the effects of response scales on human sensation and perception in moderate indoor environments. Four different response scales were compared under three room temperatures (19.0 °C, 24.5 °C, and 30.0 °C) and five acoustic stimuli (ambient noise, 42 and 61 dBA × water sounds and traffic noise): a bipolar seven-point scale according to ISO 10551:1995, a unipolar 11-point scale according to ISO/TS 15666:2003, these two scales combined for each sensory comfort assessment, and a bipolar visual analogue scale. The degree of relative differentiation based on indoor physical factors made no significant difference across the four response scales. Therefore, the effects of physical factors on human response could be assessed by using any of the four scales tested in this study, with a statistical significance at P < 0.05 in moderate environments. The choice of response scale would depend not only on the type of physical stimulus but also on the question of sensation or perception. The reliability of each response scale was different according to the subjective attributes. The bipolar visual analogue scale was subjectively preferred by the respondents.
Individual Creativity and Organizational Innovation: Can We Reconcile Creativity with Management Control Systems?

Organizations often rely on management control systems to stimulate individual creativity and organizational innovation. However, organizations face a serious problem using formal controls to stimulate creativity because extrinsic motivation (motivation induced by external rewards, such as monetary incentives) can sometimes crowd out intrinsic motivation (motivation linked to intrinsic satisfaction in performing a task) to be creative. Still, formal control systems are necessary to coordinate individuals’ creative activities with others, especially when many individuals work interdependently on complex and large projects. We shed light on this management control dilemma by reviewing early and recent studies and examine empirical evidence. We call for further research on how management control systems can stimulate creativity in a manner consistent with organizations’ best interests.
Comparison of Dengue Transmission in Lowland and Highland Area: Case Study in Semarang and Malang, Indonesia

Dengue is a potentially lethal mosquito-borne disease, regarded as the most dangerous disease in the world. It is also a major health issue in tropical and subtropical countries. Environmental characteristics and sociocultural are factors which play a role in the spread of dengue. Different landscape structure such as lowland and highland areas are possible to give different infection rate on dengue transmission. Semarang and Malang are densely populated areas in Java, which are selected to be our study areas. A mathematical model (SIR-UV) is adapted to describe dengue transmission. Spiral dynamic optimization is applied to convert monthly data to weekly in Malang and estimate the infection rate that minimized the deviation between dengue data and simulation. This method produces a good fitting to the data. We compare the pattern of dengue cases from the simulation in both cities. Furthermore, we identify seasonal variations of the cases via Fourier series of the infection rate. We also investigate the correlation between humidity, infection rate, and dengue cases in Semarang and Malang. It reveals that humidity influences infection rate in 1-3 weeks later and the infection rate produces dengue cases in the next four weeks.
Linking employees’ affective commitment and knowledge sharing for an increased customer orientation

Purpose Building on the attitude–behavior relationship model, this study aims to contribute to customer orientation literature by suggesting that service employees’ commitment (i.e. personal attitude) affects their customer orientation via the effect of their participation in knowledge sharing with colleagues (i.e. employees’ behavior). Design/methodology/approach The empirical analysis has been developed around survey data, collected from 165 service workers of Italian museums. The hypotheses are tested through the SPSS PROCESS macro plugin. Findings Drawing on the importance of human capital to tourism organizations, this study illustrates that affective commitment has a positive and significant influence on employees’ customer orientation, and that this relationship is fully mediated by knowledge-sharing behaviors. Practical implications As attitudes are more stable than behaviors, the findings suggest that managers of tourism organizations implement appropriate selection and recruitment techniques, together with adequate involvement and empowerment activities, to identify and support individuals whose attitudes fit the organizational goals. Originality/value Acknowledging the contribution that workers can give to service organizations’ success, this paper enriches the understanding of the mechanisms that underlie the relationship between employees’ attitudes and their orientation toward the customer. Building on the cognitive dissonance theory, it adds to extant research on the individual antecedents of employees’ customer orientation by shedding light on the attitude–behavior relationship in tourism organizations.
Lateral facies variations in the Triassic Dachstein platform: A challenge for cyclostratigraphy

The Triassic Dachstein platform limestone at Steinernes Meer, Salzburg, Austria, includes 611 m of limestone with 222 peritidal cycles overlain by 273 m of subtidal, non‐cyclic and weakly cyclic limestone. Cycle patterns include both shoaling and deepening upward, symmetrical, truncated, and couplets without a depth vector. Beds are laterally discontinuous, and cycle bounding surfaces are laterally variable in the studied strata. Of 558 subtidal and intertidal beds measured, 121 (21.7%) disappear laterally. An additional 73 beds (13.1%) show significant (>10%) lateral variations in thickness. Mean thickness variation is 49%. Both lateral variations and terminations appear to lack a spatial vector. Disappearances toward the inferred platform interior (west) total 10% of the beds. East, toward the platform margin, 11.6% of the beds disappear. Thickness changes occur in 6.5% of beds in each direction. The lack of lateral continuity of beds precludes a simple allocyclic forcing model and is consistent with a non‐eustatic component to stratification. Erosion of intertidal intervals is the process that can be most readily documented. Non‐uniform rates of production, transport and distribution of sediments, superposed on stratigraphic sequences driven by eustasy, probably also contributed to the complex cycle patterns recorded in the Dachstein. Such composites of autocyclic and extrabasinal factors should not be uncritically interpreted as exclusive records of orbital forcing. Lateral discontinuities and thickness variations would also produce inaccuracies in spectral analysis of thickness patterns, typically conducted in search of ‘Milankovich frequencies’, as well as in construction of Fischer plots to analyse long‐period oscillations in accommodation. Any section subjected to cycle analysis should be examined for lateral changes, to the extent permitted by the exposures, in order to produce the most complete (composite) section possible.
Novel Symmetric Modular Hybrid Multilevel Inverter With Reduced Number of Semiconductors and Low-Voltage Stress Across Switches

In this paper, by using a modular hybrid structure, a new topology for symmetric multilevel inverters (MLIs) with a small number of semiconductors and low voltage stress across switches is proposed. Despite many other topologies, this topology can inherently produce negative and zero levels without using the H-bridge. The voltage stress across a particular switch of the proposed MLI is inversely proportional to the switching frequency of that switch in a voltage period. The proposed structure is based on two types of modules, that is, the f-module and the e-module. The e-module uses a capacitive voltage divider to double the number of nonzero levels. The voltages of the capacitors are approximately balanced without complex control methods. The basic structure of the proposed topology is formed by connecting the f-module and the e-module in series with each other, and the cascaded topology is developed by cascading multiple f-modules with an e-module. To investigate the proposed topology and prove its practicability, simulation results obtained using MATLAB/Simulink, analysis of the capacitor voltages, and experimental results are presented. A comparative study is also performed to show the merit of the new MLI over other topologies.
Adverse Health Effects Associated with Long-term Exposure to Fine Particulate Matter at Levels below 12 µg/m3

Background: Ambient PM2.5 was ranked the eighth leading risk for mortality in 2017, with a total of 2.94 million associated deaths globally. Numerous studies have reported associations between long-term exposure to PM2.5 and adverse health effects across a broad range of PM2.5 concentrations. However, there is little research on the effect of concentrations below the annual PM2.5 National Ambient Air Quality Standards (NAAQS) of 12 μg/m3. Objective: Our objective was to assess the association between the levels of ambient PM2.5 below NAAQS and chronic obstructive pulmonary disease (COPD), asthma, myocardial infraction (MI) as captured by hospital admissions; emergency department visits; and mortality. Methods: We conducted a cross-sectional study on 2014 data from 265 counties of 27 States of the United States (US) retrieved from the Environmental Public Health Tracking Network (EPHTN) of the Centers for Disease Control and Prevention (CDC). We used linear and multiple linear regression models to assess the association using SAS software. Results: At levels below 12 μg/m3, controlling for heat index, a 1-unit change in annual PM2.5 concentrations was linked with an increase of 2.97 (95%CI: 1.32, 6.69)-unit in COPD hospitalizations, a decrease of 0.95 (95%CI: 0.90, 0.99)-unit in COPD EDV, an increase of 2.75 (95%CI: 1.21, 6.23)-unit in asthma hospitalizations, and an increase of 2.83 (95%CI: 1.34, 5.93)unit in asthma EDV. Additionally, long-term exposure to PM2.5 was still associated with some outcomes when concentrations were gradually lowered to level below a 9 μg/m3 threshold. Conclusion: Our results showed the association between long-term exposure to PM2.5 and COPD, asthma, and MI for PM2.5 levels below 12.0 μg/m3. Our findings provide evidence of increase health risk below current regulatory standards. Adverse Health Effects Associated with Long-term Exposure to Fine Particulate Matter at Levels below 12 μg/m3

Securing the blue: political ecologies of the blue economy in Africa

The Blue Economy concept is being embraced enthusiastically in Africa, both internally and externally. However, this new framing creates and calls for new understandings of how actors and places relate to one another, control, and create meaning and value. Thus, understanding the ocean - and its conceptual and material fabric - in this context, is a matter of political ecology, raising a number of questions that extend across geographies, spatio-temporalities, and political actors, both human and more-than-human. In this article, we flesh out these questions. An understanding of historical efforts to legally secure oceanic space can help contextualize the emergent African blue economy, one which we propose rests predominantly on the notion of 'security. ' We demonstrate how resources are economically, environmentally, and politically 'secured' as they are first constructed as economic objects of accumulation, then militarized as matters of geopolitical security, and finally controlled through technologies of monitoring, surveillance, and resistance. The 'security' of the blue growth agenda and its effects operates across different temporal and spatial dimensions and are realized in different ways across the continent as explored in the six articles in this Special Section. Keywords : blue economy, deep sea mining, political ecology, oceanic space, security
Mind on Breathing: The Effects of a Mindfulness Breathing Exercise on Academic Engagement

Author(s): Cornell, Benjamin | Advisor(s): Johnson, Austin | Abstract: The Mind-on-Breathing (MOB) intervention is a mindfulness-breathing exercise that aims to help promote student academic engagement (AE) and reduce off-task behaviors (OFT). MOB is designed from simple, shared technical features common to meditation, mindfulness, and breathing-related exercises that can be implemented in one-on-one settings with minimal training and no monetary cost. Using a multiple baseline design, the effects of MOB on student academic engagement and off-task behaviors were investigated with a sample of three 5th grade students. Systematic Direct Observation (SDO) was used to collect data on academic engagement and off-task behaviors using momentary time sampling and partial-recording, respectively. Results were interpreted using visual analysis as well as nonparametric effect size estimates (i.e., Percent of nonoverlapping data; PND; Scruggs, Mastrodieri, a Casto, 1987, Tau U; Parker, Vannest, Davis, a Sauber, 2011). Data suggested that MOB was effective for all three participants in increasing academic engagement and reducing off-task behaviors. Implications for interpreting results within a behavioral framework for implementation in a multitiered system of supports (MTSS) are provided.
A Meta-Analysis of Interpersonal and Organizational Workplace Deviance Research

Workplace deviance research has expanded rapidly over the past decade. Despite the expansive body of research available, we have an incomplete understanding of the measurement, magnitude, and direction of relationships within workplace deviance’s nomological network. We draw from 235 empirical samples of data (k = 235, N = 66,990) to conduct random-effects meta-analyses of interpersonal (k = 156, N = 42,239) and organizational (k = 206, N = 60,008) workplace deviance research so we can build the solid foundation necessary to advance the conversation in this literature. We use an exploratory meta-analytic approach and the horizontal contrasting method of theory elaboration to provide a nuanced understanding of the relationship between interpersonal and organizational deviance (ρ = .67, k = 110, N = 30,426) as well as determine the magnitude and generalizability (i.e., external validity) of relationships within their nomological networks. We find some evidence of differences (i.e., heterogeneity) in the measurement and magnitude of relationships across contexts. Overall, we conduct a state-of-the-art meta-analysis that leverages contemporary meta-analytic techniques and the extensive body of empirical workplace deviance research available to improve our understanding of the measurement of workplace deviance and relationships within its nomological network. Our study instigates new debates about the completeness of our understanding of workplace deviance and provides the empirical building blocks necessary for this literature to reach its unrealized potential.
Lower Eocene Footprints from Northwest Washington, USA. Part 1: Reptile Tracks

Lower Eocene fluvial strata in the Chuckanut Formation preserve abundant bird and mammal tracks. Reptile trace fossils include footprints from a small turtle (ichnogenus Chelonipus), and several Crocodylian trackways that consist of irregularly spaced footprints associated with linear tail drag marks. The latter trackways represent “punting” locomotion, where a submerged Crocodylian used intermittent substrate contacts to provide forward motion of their neutrally buoyant bodies. Two adjacent sandstone blocks preserve Crocodylian trace fossils that are named herein as a new ichnogenus and ichnospecies Anticusuchipes amnis. Two other Crocodylian trackways lack sufficient detail for ichnotaxonomic assignment.
