Direct and indirect effects of crime-related media consumption on public confidence in the police

This study explores the potential links between crime-related media consumption and confidence in the police based on the instrumental and expressive models. Drawing on data from a large sample of South Koreans, direct and indirect effects of crime-related media consumption on perceptions of police are examined using a regression-based multiple mediation analysis. Results showed that while there is no direct effect of media consumption on confidence in the police, crime-related media consumption is significantly and negatively associated with public confidence in the police via perceived incivilities and fear of crime. This study suggests that the police should make a constant effort to develop strategies to enhance communication with the public

Simultaneous VLBI Astrometry of H2O and SiO Masers toward the Semiregular Variable R Crateris

We obtained, for the first time, astrometrically registered maps of the 22.2 GHz H2O and 42.8, 43.1, and 86.2 GHz SiO maser emission toward the semiregular b-type variable (SRb) R Crateris, at three epochs (2015 May 21, and 2016 January 7 and 26) using the Korean Very-long-baseline Interferometry Network. The SiO masers show a ring-like spatial structure, while the H2O maser shows a very asymmetric one-side outflow structure, which is located at the southern part of the ring-like SiO maser feature. We also found that the 86.2 GHz SiO maser spots are distributed in an inner region, compared to those of the 43.1 GHz SiO maser, which is different from all previously known distributions of the 86.2 GHz SiO masers in variable stars. The different distribution of the 86.2 GHz SiO maser seems to be related to the complex dynamics caused by the overtone pulsation mode of the SRb R Crateris. Furthermore, we estimated the position of the central star based on the ring fitting of the SiO masers, which is essential for interpreting the morphology and kinematics of a circumstellar envelope. The estimated stellar coordinate corresponds well to the position measured by Gaia

An examination of the shadow of sexual assault hypothesis among men and women in South Korea

Using a South Korean sample from 2010 National Crime Victim Survey (NCVS), the current research examined the gender differences of fear of four different types of crime testing the shadow of sexual assault thesis, which asserts that sexual assault operates as a master offense for females. The current study provides insight into the robustness of the shadow hypothesis by controlling for various covariates (e.g., perceptions of the neighborhood and crime-related media consumption) that have been often omitted in this line of literature. Results show that the largest difference in fear between males and females was the fear of sexual assault, and based on coefficient comparison tests, fear of sexual assault was a stronger predictor of fear of other crimes among males than among females. The current study calls for future research to disentangle the shadow of sexual hypothesis in different settings and to conduct more studies specifically on men’s fear of crime

The Influence of Grain Size on the Mechanical Damping Behavior of Aluminum

An understanding of the fundamental correlation between grain size and material damping is crucial for the successful development of structural components offering high strength and good mechanical energy absorption. With this regard, we fabricated aluminum sheets with grain sizes ranging from tens of microns down to 60 nm and investigated their tensile properties and mechanical damping behavior. An obvious transition of the damping mechanism was observed at nanoscale grain sizes, and the underlying causes by grain boundaries were interpreted

The Effect of Task-Oriented Activities Training on Upper-Limb Function, Daily Activities, and Quality of Life in Chronic Stroke Patients: A Randomized Controlled Trial

This randomized controlled study aimed to investigate the effects of 8-week task-oriented activities of daily living (T-ADL) training on upper limb functions, activities of daily living (ADL), and quality of life (QoL) in chronic stroke patients. The 33 patients were randomly assigned to the T-ADL training or conventional occupational therapy (OT) group. The respective interventions were provided for 45-min a day, five times a week for eight weeks. To compare the upper-limb function before and after the intervention, the manual function test (MFT), box and block test (BBT), and grasp power test were performed; to compare the level of ADL performance, the modified-Barthel index (MBI) was measured. To evaluate QoL, stroke-specific QoL was measured. There was a significant group-by-time interaction in the affected side MFT score and both sides of BBT scores, but no significant interaction was found in the unaffected side MFT score, ADL, and QoL. Both groups showed a significant main effect of time in their ADL and QoL after the intervention (p < 0.001). The results of this study indicate that the eight-week T-ADL training has a positive effect on upper limb functions and gross manual dexterity, and both T-ADL training and conventional OT are effective in improving ADL and QoL in chronic stroke patients

Wearable Inertial Sensor-Based Hand-Guiding Gestures Recognition Method Robust to Significant Changes in the Body-Alignment of Subject

The accuracy of the wearable inertia-measurement-unit (IMU)-sensor-based gesture recognition may be significantly affected by undesired changes in the body-fixed frame and the sensor-fixed frame according to the change in the subject and the sensor attachment. In this study, we proposed a novel wearable IMU-sensor-based hand-guiding gesture recognition method robust to significant changes in the subject’s body alignment based on the floating body-fixed frame method and the bi-directional long short-term memory (bi-LSTM). Through comparative experimental studies with the other two methods, it was confirmed that aligning the sensor-fixed frame with the reference frame of the human body and updating the reference frame according to the change in the subject’s body-heading direction helped improve the generalization performance of the gesture recognition model. As a result, the proposed floating body-fixed frame method showed a 91.7% test accuracy, confirming that it was appropriate for gesture recognition under significant changes in the subject’s body alignment during gestures

Role conflict, entrepreneurial identity, and academic entrepreneurship: the effects of immigration status

University scientists have been strongly encouraged by administrators to engage in academic entrepreneurship (AE), via patenting, licensing, and startup formation. AE is a key aspect of the rise of “entrepreneurial universities” as discussed by (Guerrero & Urbano, Journal of Technology Transfer, 37(1), 43–74, 2012). We examine the relationship between role conflict and scientists’ propensity to engage in AE. Our model starts with the realization that academics contemplating AE struggle with multiple identities as scientists and entrepreneurs and different roles. We hypothesize that foreign-born scientists are more adept at developing an entrepreneurial identity and managing role conflict, which makes them more likely to engage in AE than their domestic counterparts. Our empirical results, based on data from 391 scientists at 25 US research universities, confirm that foreign-born scientists are well-positioned for AE and that engagement in AE mediates the positive impact of foreign-born status on entrepreneurial identity. The results imply that a more open immigration policy will generate higher levels of AE

Assessing differences between university and federal laboratory postdoctoral scientists in technology transfer

While there are numerous studies of university technology transfer, there have been relatively few studies of technology transfer at federal labs. Moreover, studies of university technology transfer have focused on faculty, not post-doctoral scientists. They have also ignored identity and sensemaking theories in organizational behavior, which are relevant in the context of technology transfer. We fill these gaps by examining differences between university post-doctoral scientists and federal lab post-doctoral scientists, in terms of how they engage in technology transfer. Our qualitative analysis is based on extensive interviews of post-doctoral scientists and their supervisors/principal investigators (PIs) at two major research universities and four large federal labs. We find that federal lab scientists are more influenced by mission-driven research and their sense of public service, as compared to university scientists who are motivated more by curiosity-driven research. These motivational differences may constitute significant barriers to technology transfer in federal labs. As compared to their university counterparts, federal lab scientists appear to experience more cognitive dissonance in pursuing commercialization of their research and have more sophisticated resolution strategies for dealing with such dissonance. We also find that PIs at federal labs are not highly incentivized to engage in technology transfer. We discuss additional research needs, as well as the managerial and training implications of our findings
