Supervisor support and work engagement: The mediating role of psychological safety in a post-restructuring business organisation

The present study aimed to examine employee perceptions of supervisor support, psychological safety, and work engagement in a restructuring mining organisation. Participants were 253 employees of a South African mining organisation (male = 65%; African = 57%; skilled supervisory technicians = 44%; and employees with 10–15 years’ experience = 23%). They completed self-report measures of supervisor support, psychological safety, and work engagement. Following structural equation modelling, results indicated that employee perception of improvement in supervisor support enhance both psychological safety and work engagement amongst retained employees. The results further indicated psychological safety to mediate the relationship between supervisor support and work engagement, thereby confirming the importance of psychological safety amongst retained employees. Psychological safety and work engagement would be important to workforce adaptation with business organisation restructuring.
Subjective knowledge and health consciousness influences on health tourism intention after the COVID-19 pandemic: A prospective study

We aimed to predict health tourism intention after the COVID-19 pandemic, which has made people more cautious about their health status. Our study participants comprised 369 people from Chengdu, China, who completed an online survey on health consciousness, subjective knowledge, perceived usefulness of health tourism, perceived behaviour control, and health tourism intention with COVID-19 mitigation measures (females = 218; age range = 18 to more than 65 years). We utilised hierarchical multiple regression and Structure Equation Modelling to predict health tourism intention from perceived usefulness of health tourism and perceived behaviour control. The results revealed that health consciousness and subjective knowledge predicted perceived usefulness of health tourism while perceived usefulness of health tourism predicted health tourism intention. Perceived behaviour control mediated the relationship between perceived usefulness of health tourism and health tourism intention partially. These findings suggest that people’s tourism intention under the COVID-19 mitigation appears to be influenced by how they perceive the usefulness of health tourism, based on their subjective knowledge and health consciousness.
Implementing the pyramid model in a turnaround elementary school

Abstract Intervention efforts in turnaround elementary schools in the U.S. have focused on academic interventions, missing the important link between students’ social emotional competence and academic outcomes. The current study describes implementation of a multi-tiered approach to support young students’ social emotional competence in an urban turnaround elementary school primarily serving students of color. Details regarding how the approach was rolled out in the school’s early childhood classrooms are offered. Lessons learned are described and discussed as part of large-scale efforts to turn around chronically underperforming urban elementary schools through a focus on improving young children’s social emotional competence.
Cultivable Microbiota Associated with Gold Ore from the Rozália Gold Mine, Hodruša-Hámre, Slovakia

Abstract Microorganisms actively participate in biogeochemical cycles of various elements in the environment, including gold. To explore the core microbiota associated with gold ore, this study examined the bacterial composition of mined rock from the Rozália gold mine (two subsurface samples from the gold mine and one from the heap of mined ore) using a cultivation approach. Cultivation analyses showed the occurrence of bacteria with colony forming units (CFU) ranging from 2.18 × 105 to 3.16 × 105 per 1 gram of dry ore material, and the data analysis indicates that the type of cultivation medium used significantly influences the observed biodiversity of cultivable bacteria. Cultivated members of the microbial community were identified using a combination of MALDI-TOF MS and 16S rRNA gene sequencing. The cultivable microbiota of gold-bearing ore samples was predominantly composed of the phylum Proteobacteria. Identification of 473 isolates revealed the presence of 4 dominant genera: Rhizobium, Microbacterium, Pseudomonas, and Acinetobacter, which together accounted for 89% of the gold ore-associated cultivated bacteria. These results are consistent with previous studies on the microbiota of gold mines and suggest that these genera constitute the core microbiota of gold ore.
Can selling traditional food increase food sovereignty for First Nations in northwestern Ontario (Canada)?

Abstract The disparity between rates of food insecurity experienced in households across Canada (8.3%) and in Indigenous households specifically (nearly half) is alarming. Many previous studies have demonstrated the physical, spiritual, mental, social and emotional benefits of consuming traditional foods (primarily wild animal food sources and wild edible plants), yet many Indigenous peoples in northern Ontario feel they do not have access to enough of them. Our research engaged in conversation with sixteen participants from four different First Nations communities in northern Ontario to explore the potential application of Greenland’s “Country Food Market” (CFM) as a model to increase accessibility of traditional food while maintaining community sovereignty over the resource. In this model, full-time hunters are financially sustained through selling their harvest at local markets. While participants were curious about the potential an economy around traditional food could have for improving access, this was tempered by cultural ethics, teachings and laws which instruct hunters to share their food and by concerns of resource overexploitation. As our research confirms, conversations and actions must move away from a binary approach to the question—either to sell or not to sell—and move toward a diverse range of economic models that center Indigenous peoples’ sovereignty.
Embedding parental input in instruction of SWPBS behavioral expectations for African American students

Abstract Schoolwide Positive Behavior Support, a framework for remediating and preventing student problem behaviors and supporting schools, has demonstrated a reduction in office disciplinary referrals (ODRs) among student groups. However, African American students are still overrepresented in ODRs. This study extended a prior study that explored parents’ perceptions of schoolwide expectations. The previous study resulted in the development of a social skill curriculum to embed parental input within the meaning of the expectations as one way to build cultural responsiveness. Specifically, authors aimed to examine the effects of the social skill curriculum on the nonadherence to classroom expectations of K-1 African American students’ using multiple-probes across participants design. Results indicated improved adherence to behavioral expectations across participants. Implications for research and practice are provided.
Promoted Media Coverage of Court Decisions: Media Gatekeeping of Court Press Releases and the Role of News Values

ABSTRACT The present study focuses on the effect of court press releases on media gatekeeping, a field that has remained largely uninvestigated to date. Using original data on the German Federal Constitutional Court, the study analyzes when court press releases are reported on in the media. Certain news values (e.g., conflict, political power, continuity/familiarity) are assumed to increase the probability that a press release will be reported on in the news. By using an automated content analysis approach, this study assesses whether 584 press releases were reported on in German newspapers over a period of eight years (2010–2018). Only press releases that promote decisions are used as they are the official information subsidies that the Court disseminates to the public through the media. Findings indicate that only 18% of press releases are reported on in the news. Furthermore, the news values of conflict and political power are found to have no influence on the success of a press release, while press releases that promote decisions with an oral hearing are more likely to be picked up by journalists. Hence, issues that are familiar to the public are more likely to be covered.
Anxiety and depression among Egyptians during COVID-19 pandemic: A cross sectional study

We conducted a cross-sectional study among 1 040 Egyptian adults (female = 56.0%; mean age = 28.8 years, SD = 7.7 years, age range 21–70 years) to assess their anxiety and depressive symptoms two weeks after the partial lockdown due to COVID-19 outbreak in Egypt. Additionally, we explored possible risk factors related to the emergence of these symptoms. The participants completed COVID-19-related questions, the Patient Health Questionnaire, and the Generalised Anxiety Disorder scale. Multiple logistic regression analysis indicated that females were more likely to develop anxiety and depression symptoms compared to males. Moreover, participants who reported following the news about COVID-19 for the whole day were 4.2 times more likely to develop anxiety and depression. Fearing stigma and worries about the nature of sanitary isolation were associated with anxiety and depression.
What’s (The) News? Reassessing “News Values” as a Concept and Methodology in the Digital Age

ABSTRACT This themed issue provides a comprehensive overview of journalism scholarship that variously builds on, develops, and re-examines the conceptual and methodological framework of “news values” research in the digital age. As such, it purports to demonstrate, explore and reflect on its distinctive merits and limitations, both actual and potential, as a distinctive approach to understanding ideas, practices, and experiences of “newsworthiness”, and indeed “news”, in the contemporary media environment and society, where the vectors of change affecting “news” production, circulation and use have been manifold. In doing so, the special issue brings together contemporary conceptual, methodological and/or empirical studies that variously contribute to the outlined research agenda. It does so by presenting scholarly work (1) situated across the constituent dimensions of news values analysis, articulating interactions between material, cognitive, social, and discursive perspectives; (2) considering the diversity of news actors and normative conceptions that make up the fragmented field of journalism; (3) crossing disciplinary boundaries within the heterogenous domain of journalism studies by integrating theoretical perspectives and exploring multi-method approaches; and/or (4) engaging digital media(technologies) or tools either as an object of study or a methodological approach.
A new strategy to toughen NbCr2 Laves phase

A new strategy to toughen NbCr2 Laves phase was proposed, in which ductile Cr and Nb solid solutions were incorporated by accelerating solute segregation within NbCr2 matrix using external applied pulsed electric current. A dense bulk consisting of ultrafine NbCr2 grains with abundant Cr and Nb solid solutions along the grain boundaries was produced by spark plasma sintering using monolithic NbCr2 starting powders. The formation of Cr and Nb solid solutions was attributed to the enhanced atomic transport, which facilitated the mobility of dislocations and the selective Joule heating. The fracture toughness of the sample achieved 11.3 MPa·m1/2, which was 9.4 times the as-cast NbCr2 (1.2 MPa·m1/2) and thus can be regarded as a new toughening mechanism.
Three-dimensional printed biodegradable poly(l-lactic acid)/(poly(d-lactic acid) scaffold as an intervention of biomedical substitute

ABSTRACT In biomedical application, the fabrication of biodegradable scaffolds using 3D printing technology has vastly increased to accommodate the complex structure of substitutes. In this study, PLLA and PDLA were hot-melt extruded for the 3D printing of PLLA/PDLA scaffolds. The incorporation of PDLA into the PLLA has enhanced the hydrophobicity and mechanical properties of the scaffolds. The degraded PLLA/PDLA scaffolds were observed to retain its chemical functionalities. Less crack formation, less acidity of the degraded solution, higher percentages of remaining weight, greater average molecular weight, and higher crystallinity percentages were recorded on the higher PDLA composition after the degradation analysis.

Academic attitude and subjective norms effects on international doctoral students’ academic performance self-perceptions: A moderated-mediation analysis of the influences of knowledge- seeking intentions and supervisor support

This study aimed to examine the relationship between international students’ academic attitude and subjective norms on the one hand, and academic self-perception on the other hand in the context of student’s perception of their knowledge- seeking intention and supervisor support. We gathered survey data from 415 international doctoral students from six top-tier universities in China (male = 61.4%; female= 38.6%; age range = 26 to 46 and above). The students were from the following regions: Asia 45.5%, Africa 40%, Europe 9.4 %, and America 5.1%. These students’ majors were engineering and technology (39.8 %), business, management, and economics (33.7%), and social sciences (26.5 %). Moderated-mediated analysis indicated higher knowledge-seeking intention to mediate the relationship between students’ academic attitude and subjective norms, and their academic performance self-perceptions. Higher self-rated supervisor support scores moderated the influences of academic attitude and subjective norms on the students’ academic performance self-perceptions. Student development and support programs should seek to support international students’ knowledge- seeking behaviours and supervisor access, enhancing their success with doctoral studies.
3-D analytical model for bending stiffness of thick-walled composite hollow shaft

In this paper, the Layer-wise theory was improve based on the alternate characteristics of layer angle of composite hollow shaft. The ±φi laminate was considered as the minimum mechanical analysis element, which can effectively simplify the stress coupling in mechanical analytical method. On this foundation, a 3-D analytical method of bending stiffness for thick-walled composite hollow shaft was derived. The CFRP hollow shaft specimens made of same dimensions but different laminate were used for bending test. Then, the bending stiffness calculated by theory of beams, 2-D analytical method, 3-D analytical model and experiment were compared. All the results show that the 3-D analytical model predicts the bending stiffness of thick-walled composite hollow shaft more precisely than the theory of beams and analytical method, and agree well with experimental results. And the 3-D analytical model can reflect the influence of stacking sequence on the bending stiffness of the composite hollow shaft.
Mapping methods of research on consumer engagement with brands on social media: A literature review

Consumer-brand engagement on social media is a widely studied research topic with high relevance for marketing practitioners. However, the discipline is affected by a conceptual divergence and limited understanding of applicable research methods. The purpose of this article is to review the extant empirical research in the marketing literature that investigates consumer engagement with brands on social media, provide an overview of the research methods employed, and suggest implications for future research. Through systematic review of 66 published studies, this article aims to explore what methods are used to empirically investigate consumer engagement with brands on social media and asks how these methods have evolved over time. The study categorises the current research and demonstrates the evolution of research methods and themes from 2011 until 2019. This literature review revealed three observations: (a) low methods’ diversity, (b) dominant reliance on visible social media metrics and (c) negative aspects of consumer brand engagement as an emerging theme. The insights developed and the observed trends can be helpful in shaping future research and practice in the field of consumer brand engagement.
Analysis and evaluation of temperature field and experiment for magnetorheological fluid testing devices

When a large amount of heat is produced during the operation of a MRF (magnetorheological fluid) testing device, the temperature of the device will increase, which will in turn affect the characteristics of the MRF. Exploring the temperature field characteristics of the MRF yield stress testing device is necessary to improve the accuracy of the device. In this study, first, the yield stress testing device is designed, and then its temperature field model, including enameled wire and assembly gap, is established. Second, simulation software is used to simulate the temperature field change. Finally, a test platform is developed to test the simulation results, especially for two factors, namely, thermal conductivity of the coil winding and assembly gap, which demonstrate considerable influence. Comprehensive thermal conductivity and assembly clearance are determined, and the optimum temperature field of the device for measuring yield stress is resulted.
Investigating Visual Crowding of Objects in Complex Real-World Scenes

Visual crowding, the impairment of object recognition in peripheral vision due to flanking objects, has generally been studied using simple stimuli on blank backgrounds. While crowding is widely assumed to occur in natural scenes, it has not been shown rigorously yet. Given that scene contexts can facilitate object recognition, crowding effects may be dampened in real-world scenes. Therefore, this study investigated crowding using objects in computer-generated real-world scenes. In two experiments, target objects were presented with four flanker objects placed uniformly around the target. Previous research indicates that crowding occurs when the distance between the target and flanker is approximately less than half the retinal eccentricity of the target. In each image, the spacing between the target and flanker objects was varied considerably above or below the standard (0.5) threshold to either suppress or facilitate the crowding effect. Experiment 1 cued the target location and then briefly flashed the scene image before participants could move their eyes. Participants then selected the target object’s category from a 15-alternative forced choice response set (including all objects shown in the scene). Experiment 2 used eye tracking to ensure participants were centrally fixating at the beginning of each trial and showed the image for the duration of the participant’s fixation. Both experiments found object recognition accuracy decreased with smaller spacing between targets and flanker objects. Thus, this study rigorously shows crowding of objects in semantically consistent real-world scenes.
Abnormal event detection algorithm based on dual attention future frame prediction and gap fusion discrimination

Abstract. Rapid and accurate detection of crowd abnormal events, such as stampedes and violent attacks in public places, has great research significance and application value. Due to the diversity and uncertainty of abnormal events, almost all existing methods tackle the problem by minimizing the reconstruction errors of training data, which cannot guarantee a larger reconstruction error for all abnormal events. According to the idea that “normal events can be predicted, abnormal events cannot be predicted,” we proposed a future frame prediction-based anomaly detection algorithm. First, the generative adversarial network (GAN) is trained by the normal videos to predict normal future frames. Then, it can determine the existence of abnormal events by identifying the difference between the ground truth and predicted video frame. In the design of the GAN, the attention module is introduced to improve the prediction level of the network. At the same time, the optical flow information is added for motion constraint to improve the constraint ability on the appearance characteristics. In the testing stage, the appearance gap and optical flow gap between the ground truth and the predicted video frame are fused to determine whether the frame is abnormal. The experimental results on the datasets of CUHK Avenue, UCSD, and ShanghaiTech show that the proposed algorithm is superior to that of the current mainstream anomaly detection algorithms.
Investigating the Diel Occurrence of Odontocetes around the Maui Nui Region Using Passive Acoustic Techniques1

Abstract: The distribution of odontocetes on a daily scale is largely driven by bottom-up processes that in turn influence foraging opportunities. Environmental variables such as bathymetry may help indicate productive foraging regions and serve as useful tools when assessing dolphin spatial and temporal patterns. To begin to understand daily spatial patterns of different odontocete species relative to heterogeneous benthic habitat, passive acoustic monitoring was conducted near an understudied basin of the Hawaiian Islands, the Maui Nui region (Maui, Lāna‘i, Kaho‘olawe, Moloka‘i). Results showed that the acoustic activity of smaller species was stronger at night than day, particularly closer to shelf waters. In contrast, the acoustic activity of less common larger species tended not to follow a diel pattern, except at sites of a moderate proximity to shelf waters. These findings support previous research showing that smaller odontocetes, such as spinner dolphins (Stenella longirostris), track and feed upon the daily vertically migrating mesopelagic boundary community at night, while larger odontocetes, such as false killer whales (Pseudorca crassidens), may forage across most of the region during both the day and night. This information will help inform best management practices that account for interspecies variation in use of the Maui Nui basin.
