CAIRNS: The Cluster And Infall Region Nearby Survey III. Environmental Dependence of H-alpha Properties of Galaxies

We investigate the environmental dependence of star formation in cluster virial regions and infall regions as part of CAIRNS (Cluster And Infall Region Nearby Survey), a large spectroscopic survey of the infall regions surrounding nine nearby rich clusters of galaxies. Our long-slit spectroscopy yields estimates of star formation rates in environments from cluster cores to the general large-scale structure. The fraction of galaxies with current star formation in their inner disks as traced by H-alpha emission increases with distance from the cluster and converges to the ``field'' value only at 2-3 virial radii, in agreement with other investigations. However, among galaxies with significant current star formation (EW[Ha]geq2\AA), there is no difference in the distribution of EW[Ha] inside and outside the virial radius. This surprising result, first seen by Carter et al., suggests that (1) star formation is truncated on either very short timescales or only at moderate and high redshifts or (2) that projection effects contaminate the measurement. The number density profiles of star-forming and non-star-forming galaxies indicate that, among galaxies projected inside the virial radius, at least half of the former and 20% of the latter are ``infall interlopers,'' galaxies in the infall region but outside the virial region. The kinematics of star-forming galaxies in the infall region closely match those of absorption-dominated galaxies. This result shows that the star forming galaxies in the infall regions are not interlopers from the field and excludes one model of the backsplash scenario of galaxy transformation. Finally, we quantify systematic uncertainties in estimating the global star formation in galaxies from their inner disks.Comment: 25 pages, 21 figures, accepted for publication in A

SITUATIONAL ANALYSIS OF COLLEGE OF EDUCATION STUDENTS`MOTIVATION TO PARTICIPATE IN SPORTING ACTIVITIES IN GHANA

COVID-19 disrupted education and school sports which resumed after the pandemic. This study explores motivational factors influencing college students' participation in sports after the pandemic with reference to gender. The study employed a rigorous descriptive methodology and simple random sampling, with four hundred (400) college student-athletes. Principal Component Factor Analysis (PCFA) identified distinct motivational factors driving student sports engagement. Mean calculations revealed the most influential factors promoting sports re-engagement. The results indicated intrinsic motivation as the foremost factor, followed by the facility and equipment factor. To determine if gender differences exist in relation to motivation to partake in sports, an independent sample t-test was used. Male students showed slightly higher intrinsic motivation and lower facility and equipment motivation than female students. Conversely, female students exhibited higher motivation regarding facilities and equipment, but greater amotivation and external regulation compared to males. It was recommended that promotion and intervention strategies consider barriers and tailor interventions to specific needs to reduce participants' limitations to sports participation.  Article visualizations

Assessing the Factors that Motivate Keep Fit Club Members in the Cape Coast Metropolis to Engage in Physical Fitness Related Activities

The purpose of this study was to conduct descriptive survey to investigate factors that motivate keep fit club members in the Cape Coast Metropolis of Ghana to engage in physical fitness related activities. Data was collected from a sample size of 100 respondents. Data was analyzed using descriptive statistics. It was revealed that most members in the Clubs keep fit mainly because of health reasons. It was recommended that keep fit clubs should find ways of helping their members to measure their improvement while keeping fit. They should learn more activities in other to vary their exercises.

Incorporating Policymaker Costs and Political Competition into Rent-Seeking Games

We incorporate policymaker costs of supplying rents and variable intensities of competition among rent seekers into the standard rent-seeking game. By incorporating these aspects, the game has greater verisimilitude to the lobbying process. The first aspect captures the fact that in rent-seeking contests there is a positive probability that neither firm will obtain the rent. The second aspect captures the fact that firms seeking different rents still must compete for policymakers\u27 resources. We find that lobbying expenditures, rent-seeking profits, and rent dissipation depend on the intensity of competition and the value of the rent relative to policymaker costs. For example, if the value of the rent is sufficiently high relative to policymakers\u27 costs, an increase in the intensity of political competition will increase lobbying expenditures; otherwise, expenditures fall as competitive intensity increases. In addition, the model establishes pure-strategy equilibria with underdissipation where only mixed-strategy equilibria exist in the standard model

Evaluation of Physical Fitness Related Practices of Keep Fit Club Members in the Cape Coast Metropolis of Ghana

The purpose of this study was to conduct descriptive survey of practices of physical fitness activities among keep fit club members in the Cape Coast Metropolis of Ghana. The study sought to find out the related physical fitness activities practices keep fit club members in question engage in to show the basic principles they need to keep fit. A sample of 100 respondents was selected for the study. The instrument used to collect data was questionnaire. Data was analyzed using descriptive statistics. It was revealed that most of the physical exercises are not common to some instructors of keep fit clubs. Some members of keep fit clubs don’t know the importance of some other practices like enough rest and regular check on their health. Also, members only treated minor injuries themselves. Most members think body composition is more important than cardiovascular development and are aware of health importance of keeping fit. It was recommended that they should learn more activities in other to vary their exercises. The issue of diet control must also be emphasized and resting as well. The duration of physical fitness activities must at least travel beyond 30 minutes. Regularity of keeping fit must also be looked at.

Level of Computer Literacy of Barangay Officials of Tandaay, Nabua, Camarines Sur: Basis for Community Extension Program

This study aims to determine the level of computer literacy of the barangay officials in Tandaay as the basis for a community extension program. Purposive sampling was used as a sampling technique to determine the respondents. With that, a total of 37 elected and appointed barangay officials comprised the study respondents. This study is a descriptive-correlational research that made use of a checklist questionnaire to gather the data. The frequency and percent distribution, weighted mean, order ranking method, and chi-square test of independence were used to interpret the collected data. The findings revealed that the elected and appointed barangay officials are “Somewhat Unaware” in terms of computer navigation skills and online communication skills. For Microsoft Office skills and computer troubleshooting skills, the respondents are found to be “Unaware”. For the factors affecting the respondents’ level of computer literacy, the result revealed that the respondents “Agree” that the indicators in computer navigation skills, Microsoft Office skills, online communication skills and computer troubleshooting skills affect their computer literacy, especially their willingness to learn and use the computer. Moreover, there is a significant difference between the respondent’s profile and their level of awareness in computer literacy. As an output, the researchers proposed an intervention plan to improve the computer literacy of the respondents. This intervention plan is a basic computer learning workshop designed and aligned based on the results of the survey

BRCA2 polymorphic stop codon K3326X and the risk of breast, prostate, and ovarian cancers

Background: The K3326X variant in BRCA2 (BRCA2*c.9976A>T; p.Lys3326*; rs11571833) has been found to be associated with small increased risks of breast cancer. However, it is not clear to what extent linkage disequilibrium with fully pathogenic mutations might account for this association. There is scant information about the effect of K3326X in other hormone-related cancers. Methods: Using weighted logistic regression, we analyzed data from the large iCOGS study including 76 637 cancer case patients and 83 796 control patients to estimate odds ratios (ORw) and 95% confidence intervals (CIs) for K3326X variant carriers in relation to breast, ovarian, and prostate cancer risks, with weights defined as probability of not having a pathogenic BRCA2 variant. Using Cox proportional hazards modeling, we also examined the associations of K3326X with breast and ovarian cancer risks among 7183 BRCA1 variant carriers. All statistical tests were two-sided. Results: The K3326X variant was associated with breast (ORw = 1.28, 95% CI = 1.17 to 1.40, P = 5.9x10- 6) and invasive ovarian cancer (ORw = 1.26, 95% CI = 1.10 to 1.43, P = 3.8x10-3). These associations were stronger for serous ovarian cancer and for estrogen receptor–negative breast cancer (ORw = 1.46, 95% CI = 1.2 to 1.70, P = 3.4x10-5 and ORw = 1.50, 95% CI = 1.28 to 1.76, P = 4.1x10-5, respectively). For BRCA1 mutation carriers, there was a statistically significant inverse association of the K3326X variant with risk of ovarian cancer (HR = 0.43, 95% CI = 0.22 to 0.84, P = .013) but no association with breast cancer. No association with prostate cancer was observed. Conclusions: Our study provides evidence that the K3326X variant is associated with risk of developing breast and ovarian cancers independent of other pathogenic variants in BRCA2. Further studies are needed to determine the biological mechanism of action responsible for these associations
