Dynamic Systems and Applications 22 (2013) 371-384 COMBINED EFFECTS FOR A STATIONARY PROBLEM WITH INDEFINITE NONLINEARITIES AND LACK OF COMPACTNESS

 −∆u − λu = k(x)u − h(x)u, if x ∈ Ω u > 0, if x ∈ Ω u = 0, if x ∈ ∂Ω , where λ ∈ R, Ω ⊂ R , N ≥ 3 is a bounded open set with smooth boundary, the functions h, k ∈ L(Ω) are nonnegative and 1 < p < q. For λ ∈ R in a neighborhood of the first eigenvalue of the Laplace operator in H 0 (Ω), they obtained the solvability of problem (1.1), as well as corresponding multiplicity properties, under various assumptions on h and k. More exactly, they proved existence, nonexistence and multiplicity results depending on λ and according to the integrability properties of the ratio k(x)/h(x). The work of Alama and Tarantello was carried on by Chabrowski [9] who obtained similar results for the problem
Direct and Stress-Buffering Effects of COVID-19-Related Changes in Exercise Activity on the Well-Being of German Sport Students

Maintaining or initiating exercise activity in the COVID-19 pandemic may act as a buffer against the observed stress-related deterioration in well-being, with emotion regulation (ER) discussed as a possible moderator. Therefore, the present study investigated the interaction between stress, exercise activity (EA), and ER on mood. In an online survey, 366 German sports science students (56% women, Mage = 23.04, SD = 2.87) reported their stress levels (general and COVID-19-specific), mood (energy, valence, calmness), EA before and during the pandemic, and use of ER strategies in spring 2020. Pandemic-related change in EA was calculated as residual change. Due to gender differences in mental health and EA, the main and interaction effects were tested in twelve hierarchical regression analyses, separately for men and women. Overall, EA significantly decreased during the pandemic and was positively associated with energy in both men and women. ER was positively associated with women’s energy, but negatively with all three mood dimensions in men. Only one three-way interaction appeared significant: in the case of high stress, low levels of EA and high use of ER were associated with the greatest deteriorations in energy in men. Our findings suggest that EA may buffer deteriorations in energy in men with high stress and difficulties in ER.

Fzcperimental data from the Great Dun Fell Cloud Experiment 1993 were used to investigate interactions between soluble gases and cloud droplets. Concentrations of HzOz, SOz, CH,COOH, HCOOH, and HCHO were monitored at different sites within and downwind of a hill cap cloud and their temporal and spatial evolution during several cloud events was investigated. Significant differences were found between in-cloud and out-of-cloud concentrations, most of which could not be explained by simple dissolution into cloud droplets. Concentration patterns were analysed in relation to the chemistry of cloud droplets and the gas/liquid equilibrium. Soluble gases do not undergo similar behaviour: CH,COOH simply dissolves in the aqueous phase and is outgassed upon cloud dissipation; instead, SO2 is consumed by its reaction with H202. The behaviour of HCOOH is more complex because there is evidence for in-cloud chemical production. The formation of HCOOH interferes with the odd hydrogen cycle by enhancing the liquid-phase production of Hz02. The HzOz concentration in cloud therefore results from the balance of consumption by oxidation of SOz, in-cloud production, and the rate by which it is supplied to the system by entrainment of new air into the clouds. 6 1997 Elsevier Science Ltd.

Children's perceptions of the factors that led to their enrolment in advanced, middle-school science

Toward the end of 6th grade, some bright and highly motivated science-oriented Israeli students and their parents are required to make a decision: whether or not to enrol in a non-mandatory advanced science programme for 7th graders (≈12 year olds) upon entering middle-school. In other words, for many students, entry into the STEM pipeline begins at an earlier age than previously reported and, to date, reasons for doing so are unknown. The aim of this study was to identify and model the factors that contributed to enrolment. Data collected from 7th graders in three Israeli middle-schools (N = 615) included selfefficacy and interest in STEM learning, perceived parental encouragement to learn STEM, perceived peer interest in STEM, recollections of STEM learning in primary schools and participation in informal STEM programmes. Path analysis showed that ‘self-efficacy’, ‘parents’, ‘peers’ and ‘participation’ directly predicted enrolment. Self-efficacy mediated the effects of environmental variables on academic choice. The significant effect of participation in informal STEM programmes points toward an even earlier entry into the STEM pipeline. Quantitative content analysis was used to categorise the reasons for enrolling in the advanced science programmes (N = 179). Unexpectedly, students overwhelmingly cited practical importance (‘utility value’) vis-à-vis short, medium and long-term goals. ARTICLE HISTORY Received 3 February 2020 Accepted 23 July 2020

Effect of Capital Strengthening, Education, and Health on Poverty Status in the City of Sawahlunto

This study aims to reveal and analyze the effect of capital strengthening, education, and health programs on poverty status in Sawahlunto City. The population in this study were the poor in the city of Sawahlunto which were spread over 4 (four) districts, namely 1) Talawi District, 2) Barangin District, 3) Lembah Segar District and 4) Silungkang District totaling 871 families. The number of samples in this study were 96 families. Sampling is done based on Random Sampling with the sampling technique "Cluster Random Sampling" because it has different characteristics. The data analysis used in this research is logistic regression analysis. The results of the study found that the strengthening of capital, education and health both partially and simultaneously had a significant effect on the poverty status of the people in the city of Sawahlunto. Providing business capital, improving education and providing health services that are not burdensome for the poor is one solution to cutting the cycle of poverty. With the availability of business capital, high education and good health, the quality of human resources will be better, so that productivity will increase which will have implications for increasing income and improving the family economy. So that the status of poverty in the city of Sawahlunto can be reduced and the community can get out of the poverty line, it is recommended that the Sawahlunto city government make improvements in providing business capital, improve the quality of human resources by organizing and providing better education and increasing the degree of public health by providing services more equitable health.
Maternal Anxiety, Infant Stress, and the Role of Live-Performed Music Therapy during NICU Stay in The Netherlands

Having an infant in the neonatal intensive care unit (NICU) elicits maternal anxiety, which may hamper parent−child bonding. We performed a prospective cohort study to describe anxiety in mothers of infants born before 30 weeks of gestation during NICU stay in The Netherlands, and investigated the influence of infant stress and gestational age. Second, we performed a randomized-controlled live-performed music therapy trial (LPMT trial) to investigate whether music therapy applied to the infant alleviated maternal anxiety. The relation between infant stress, gestational age, and maternal anxiety was measured in 45 mother−infant dyads, using the Neonatal Infant Stressor Scale and the State-Trait Anxiety Inventory (STAI). The effect of LPMT on anxiety was assessed in 21 mothers whose infants were assigned to either LPMT (n = 12) or waitlist (n = 9). Mothers completed the STAI before and after this period. Maternal anxiety decreased over time in all mothers, and was strongly related with infant stress (r = 0.706, p < 0.001), but not with gestational age. Anxiety scores decreased by 12% after LMPT, and increased by 1% after a waitlist period (p = 0.30). Our results indicate that LPMT in the weeks after birth may accelerate the reduction of maternal anxiety. Further research should focus on the effects on mother−child bonding.
Characterizing Adversarial Transferability via Gradient Orthogonality and Smoothness

Transferability is an intriguing property of adversarial examples. In this work we aim to ﬁrst understand the sufﬁcient conditions of transfer-ability. A theoretical analysis yields two lower bounds for transferability based on data distribution similarity and model gradient similarity. We then prove an upper bound on transferability for low risk classiﬁers based on gradient orthogonality and smoothness. We demonstrate that under the condition of gradient orthogonality, smoother classiﬁers guarantee lower transferability. Finally, based on our theoretical analysis of transferability, we propose a simple yet effective strategy to train a robust ensemble with low transferability by enforcing model smoothness and gradient orthogonality between base models.
Multigene phylogeny and taxonomic revision of American shrimps of the genus Cryphiops Dana, 1852 (Decapoda, Palaemonidae) implies a proposal for reversal of precedence with Macrobrachium Spence Bate, 1868

Abstract The freshwater shrimp genus Cryphiops Dana, 1852 has a disjunct distribution in North (Mexico) and South (Brazil, Chile) America, and is composed of only six species. The current classification of genera in the Palaemonidae is controversial, based on variable morphological characters, and still far from a clear definition. Cryphiops differs from the speciose genus Macrobrachium Spence Bate, 1868 only by the absence of the hepatic spines on the carapace. Previous studies with a limited dataset suggested the necessity to link morphology and phylogeny to create an internal rearrangement in the genus to resolve the paraphyletic status. Through a molecular phylogenetic approach, the evolutionary relationships are inferred based on four (mitochondrial and nuclear) genes, among all recognized species of Cryphiops and, in combination with a taxonomic revision, a rearrangement in the systematics of the genus is suggested. The absence of hepatic spines on the carapace, the only character used to separate the genus Cryphiops, is subjective and should be considered as a homoplasy. This implies that Cryphiops and Macrobrachium are subjective synonyms and, because the latter genus is much more diverse and widely known, with several economically important species, to avoid confusion and disturbance in nomenclatural stability and keep universality, a proposal for the priority of the older synonym (Cryphiops) to be partially suppressed in favor of maintaining the prevailing use of the younger synonym (Macrobrachium) is presented. As the species of Cryphiops should be accommodated in the genus Macrobrachium, new names to replace three preoccupied specific names that, by this action, resulted to be secondary homonyms are offered.
Severe Acute Respiratory Syndrome by COVID-19 in pregnant and postpartum women

Abstract Objectives: to evaluate the morbidity and mortality profile and factors associated with death due to severe acute respiratory syndrome (SARS) by COVID-19 in pregnant and postpartum women. Methods: this is a quantitative and retrospective research that analyzed the SIVEP-gripe Database (Influenza Epidemiological Surveillance Information System), from 01/01/2020 to 04/01/2021. All pregnant women and postpartum women diagnosed with SARS caused by COVID-19 in the State of Minas Gerais were included. After the descriptive analysis of the hospitalizations profile, the association between different exposure variables and the occurrence of death was evaluated. Results: of the 227 records obtained, 94.3% required hospitalization. Among hospitalizations in the Intensive Care Unit, 29.8% used invasive ventilatory support. Fifteen deaths were recorded. The most frequent clinical manifestations were: cough and fever; the predominant comorbidities were cardiovascular disease and diabetes mellitus. The variables “ICU stay”, “use of ventilatory support” and “heart disease” were associated with the occurrence of deaths. Conclusions: hospitalization was necessary for most pregnant women with SARS and the presence of previous heart disease increased the risk of death. Knowing the SARS morbidity and mortality profile is important in the definition of public health strategies aimed at reducing the impacts of COVID-19 during pregnancy and the puerperium.
Practicing Religion during a Pandemic: On Religious Routines, Embodiment, and Performativity

This article aims to investigate how the COVID-19 pandemic has affected the religious lifestyles of practicing female Roman Catholics in Belgium. I explore how these Catholic believers manage to stay in touch with their faith and faith community in times of crisis when physical and real-life contact is very limited. In this article, I draw on in-depth interviews conducted via Zoom, carried out in the framework of my current ethnographic research project. The empirical results show how Catholic women grappled with the multiple lockdowns during the last year and a half, and how the lockdowns led to severe changes in their religious practices and routines. Many believers had to find alternative possibilities and modalities in order to preserve continuity with their religious pre-COVID-19 lives. Throughout the article, I intend to map their practices and strategies. I will argue that inquiring how religion and religious practices are performed during a pandemic can contribute to the flourishing and timely scholarship on digital and online religion and it also provides us with further insights in the performativity, materiality, and embodiment of religion.
Internalization of Entrepreneurial Values on Written Batik Craftsmen in Creating Business Independence

This research examines the implementation of the entrepreneurial values internalization, its benefits, and impacts in establishing business independence in the written batik industry. The internalization of entrepreneurial values needs to be instilled in batik craftsmen to maintain their business. It helps individuals develop a creative, resilient, unyielding, honest, and good personality. This was a case study that utilized a qualitative approach design. The research data was extracted using key and supporting informants, specifically business owners and employees and customers. The snowball sampling technique was used to collect the informant data. Furthermore, data analysis involved reduction, display, verification, and drawing conclusion, while triangulation was used to determine the validity of data sources and methods. The results showed that business owners and employees implement entrepreneurial values, including responsibility, knowledge of personal abilities, good personality, creativity, innovation, and courage to take risks. The internalization of entrepreneurial values implanted and implemented fosters creativity and innovation in creating new batik motifs. Creativity and innovation are the main keys to business independence, which is essential for
Nonlinear double-beam system dynamics

Abstract: Double-beam model is considered in many investigations both theoretical and typically engineering ones. One can find different studies concerning analysis of such structures behaviour, especially in the cases where the system is subjected to dynamic excitations. This kind of model is successfully considered as a reliable representation of railway track. Inclusion of nonlinear physical and geometrical properties of rail track components has been justified by various computational studies and theoretical analyses. In order to properly describe behaviour of real structures their nonlinear properties cannot be omitted. Therefore a necessity to search appropriate analytical nonlinear models is recognized and highlighted in published literature. This paper presents essential extension of previously carried out double-beam system analysis. Two nonlinear factors are taken into account and parametrical analysis of the semi-analytical solution is undertaken with special emphasis on different range of parameters describing nonlinear stiffness of foundation and layer between beams. This study is extended by preliminary discussion regarding the dynamic effects produced by a series of loads moving along the upper beam. A new solution for the case of several forces acting on the upper beam with different frequencies of their variations in time is presented and briefly discussed.
Readiness to Implement Digital Learning

WHO announced the Covid-19 as Global Pandemic in early 2020? This condition immediately urged universities to migrate their instructional process to fully online learning as a result of the suggestion of physical distancing. This situation indeed results in the shock of the culture of learning and teaching. Following its shock, of course, questions arise related to the readiness of higher education in implementing fully online learning. This study aims to measure the readiness of lecturers and students of the Faculty of Economics, Universitas Negeri Medan (Unimed), in implementing digital learning. This study investigates the readiness from the normative belief perspectives. Normative belief is one of the critical antecedents of behavioral intention, as explained in The Theory of Planned Behavior [1]. The respondents of this study were lecturers and students at the Faculty of Economics, Unimed. This study uses simple random sampling to select the sample. With the snowball technique, this study collected 226 responses. 85 respondents were a lecturer, and 141 was a student. Data collection was carried out with an electronic questionnaire designed with 5-Likert scales. This study examines the differences of responses between lecturers and students as well as between men and women to avoid response bias. The results of this study indicate that lecturers and students have firm beliefs regarding their readiness to migrate learning activities to the online platform. Likewise, the findings of this study also indicate nervousness in the migration. The results of this study provide challenges for learning researchers and Education technology to produce recommendations for learning models that are suitable for implementing quality learning on digital platforms. The same challenge is faced with universities and regulators to develop best practices in teaching practices and regulations that urge innovation in teaching practices.
Quadrupole noise generated from a low-speed aerofoil in near- and full-stall conditions

Abstract In this paper, direct numerical simulations are performed for low-speed flows past a NACA0012 aerofoil at high incidence angles. The aim is to investigate the significance of quadrupole noise generated due to separated shear layers, in comparison to dipole noise emanating from the aerofoil surface. The two different noise components (dipole and quadrupole) are calculated by using the Ffowcs Williams & Hawkings method in two different approaches: one with a solid surface and another with a permeable surface. The quadrupole noise is then estimated approximately by taking the relative difference between the two. The current study provides detailed comparisons between the quadrupole and dipole noise components at various observer locations in a wide range of frequencies. The comparisons are also made in terms of Mach number scaling, which differs significantly from theoretical predictions and changes rapidly with frequency. Additionally, pre-, near- and full-stall conditions are cross-examined, which reveals significant differences in the quadrupole contributions, including changes in the major source locations and frequencies. It is found that the inclusion of the quadrupole sources gives rise to the predicted noise power level at all frequencies (varying between 2 and 10 dB for an observer above the aerofoil) compared to the dipole-only case. The quadrupole contribution is far from negligible even at the low subsonic speeds (Mach 0.3 and 0.4) when aerofoil stall occurs.
Retrospective analysis of the role of cyclin E1 overexpression as a predictive marker for the efficacy of bevacizumab in platinum-sensitive recurrent ovarian cancer

The relative benefit of bevacizumab in ovarian cancer (OC) patients is greater the more the disease becomes platinum-resistant. Among other mechanisms of action, antiangiogenic agents may induce homologous recombination deficiency. Cyclin E1 (CCNE1) overexpression is a proposed marker of platinum resistance and is mutually exclusive with deficiency in homologous recombination. In this study, we evaluated the predictive value of CCNE1 expression with regard to the efficacy of bevacizumab. We retrospectively evaluated data from patients with platinum-sensitive recurrent OC who were treated with chemotherapy (CT) plus bevacizumab (Bev group) or CT alone (CT group) at a tertiary cancer centre from 2005 to 2017. The two groups were paired according to histology, platinum-free interval (PFI) and number of previous treatment lines. Progression-free survival (PFS) was compared between groups by log rank test and Cox regression. A total of 124 patients were included, with 62 in each group. The groups were well balanced regarding histology, PFI and number of previous treatment lines. Median PFS (mPFS) was 19.5 months for the Bev group versus 16.0 months for CT group (p = 0.150). By multivariate analysis, the HR for PFS was 2.25 (95% CI: 1.10–4.60) for CCNE1 overexpression. The benefit of bevacizumab was larger in the subgroups of patients with PFI 6–12 months (mPFS 18.6 versus 10.4 months, p = 0.002) and CCNE1 overexpression (mPFS 16.3 versus 7.0 months, p = 0.010). In conclusion, CCNE1 overexpression and PFI may suggest which patients will receive the greatest benefit from bevacizumab. These data, if confirmed by other studies, could help better select patients for antiangiogenic therapy.
Examining Non-Native English Speaking Academics’ Communication Apprehension in International Academic Meetings: A Turkish Context

This study aims to investigate the sources of communication apprehension in foreign language experienced by Turkish academics working at state universities (e.g., nonnative speakers of English) in international academic meetings and their perceptions towards this matter. As the sample of the study, 44 (20 females and 24 males) participants were selected from voluntary academics from two universities. Using the quantitative research design, the data were collected by the Foreign Language Anxiety Scale (Horwitz, Horwitz, & Cope, 1986) and Personal Communication Fear Scale (McCroskey, 1982). The results indicated that although female participants have higher levels of FLA than male participants, there were no significant differences by genders.
