It was recommended that educators and policymakers need to focus on nurturing, developing and fostering students' resilient abilities through targeted interventions and teaching strategies.

Adoption of International Public Sector Accounting Standards and Financial Reporting Quality in Universities in Rivers State

In spite of the adoption of International Public Sector Accounting Standards (IPSAS) in Nigeria, it appears that significant progress has not been made by public sector organisations in its implementation. The purpose of this study was to investigate the extent to which the adoption of IPSAS has influenced financial reporting quality in universities in Rivers State. Cross sectional survey research design was used for the study and the area of the study was Rivers State, Nigeria. The population of the study was 37 senior Accounting Personnel from the three universities studied. The entire population of 37 was used as sample, hence census was employed for the study. The instrument used for the collection of data was a self-structured questionnaire developed using a four-point rating scale of Very High Extent, High Extent, Moderate Extent and Low Extent. The instrument was validated by two Business Educators and one Measurement and Evaluation expert, all from the Faculty of Education, Rivers State University. The reliability of the instrument was determined using the test re-test method; this was done through the Pearson Product Moment Correlation Coefficient (PPMCC) and a reliability coefficient of 0.96 was obtained. Data was analysed using mean and standard deviation while the hypothesis was tested using one-way Analysis of Variance. Based on the results of the study, it was found that the adoption of international public sector accounting standards has influenced financial reporting quality in universities in Rivers State albeit to a moderate extent. The study further found that there was significant difference in the mean score of Senior Accounting Personnel in the three universities on the extent to which financial performance, financial position and cash flow standards have influenced financial reporting quality in universities in Rivers State. The study concludes that universities in Rivers State are still at an elementary stage of the adoption of IPSAS in the preparation of financial statements and as such the quality of their financial statements cannot be reasonably assured. One recommendation made, amongst others, was that Accounting Personnel of universities in Rivers State, especially those handling Final Accounts, should be made to undergo thorough training on IPSAS to enhance their financial reporting skills; the training should be practical and not theory-based and experts who have been involved in the successful implementation of IPSAS should champion the process.

Evaluating Gait with Force Sensing Insoles 6 Months after Anterior Cruciate Ligament Reconstruction: An Autograft Comparison.

Aberrant knee mechanics during gait 6 months after anterior cruciate ligament reconstruction (ACLR) are associated with markers of knee cartilage degeneration. The purpose of this study was to compare loading during walking gait in QT, bone-patellar tendon-bone (BPTB), and hamstring tendon (HT) autograft patients 6 months post-ACLR using loadsol single sensor insoles, and to evaluate associations between loading and patient reported outcomes. 72 patients (13-40 years) who underwent unilateral, primary ACLR with BPTB, QT, or HT autograft completed treadmill gait assessment, the International Knee Documentation Committee (IKDC) survey and the ACL-Return to Sport after Injury (ACL-RSI) survey 6 ± 1 months post-ACLR. Ground reaction forces were collected using loadsols. Limb symmetry indices (LSI) for peak impact force (PIF), loading response instantaneous loading rate (ILR), and loading response average loading rate (ALR) were compared between groups using separate ANCOVAs. Survey scores were compared between groups using one-way ANOVAs. The relationships between IKDC, ACL-RSI, and LSIs were compared using Pearson's product moment correlation coefficients. There were no significant differences between graft sources for LSI in PIF, ILR, ALR, nor impulse. Patient-reported knee function was significantly different between graft source groups with the BPTB group reporting the highest IKDC scores; however, there was no significant difference between groups for ACL-RSI score. There were no significant associations between IKDC score, ACL-RSI score, and biomechanical symmetry among any of the graft source groups. Autograft type does not influence PIF, ILR, ALR, or impulse during walking 6 months post-ACLR. Limb symmetry during gait is not strongly associated with patient reported outcomes regardless of graft source. Loadsols appear to be a suitable tool for use in the clinical rehabilitation setting.

Tertiary Agricultural Students’ Proclivity to Use Social Media for Improving Learning Outcomes During the COVID-19 Pandemic Era in Oyo State, Nigeria

The COVID-19 pandemic caused significant disruptions in the higher education industry, leading to program closures and delays. Institutions were asked to adopt Web 2.0 teaching methods, including Social Media (SM), for engagement and multitasking. Despite this, educational institutions are yet to harness SM’s potential to improve learning outcomes among students. Hence, this study investigated students’ proclivity to use social media for improving learning outcomes during the COVID-19 pandemic era in Oyo State, Nigeria. A multi-stage sampling procedure was used to select a total of 210 respondents. Data were collected quantitatively through questionnaires on respondents' socioeconomic characteristics, knowledge, learning outcomes, and proclivity to use SM. Data were analyzed using frequency count, percentage, mean, Pearson Product Moment Correlation, and linear regression at α0.05. Respondents’ average age was 23.96±3.52 years, majority (61.1%) were female, single (90.9%), and Christians (74.5%). Most (68.8%) students depended on their parents/guardians for their source of income, with an average monthly income of #30,418.27±56322.51. Majority (66.8%) had high knowledge of SM usage and learning outcomes (61.1%). Most (53.4%) indicated a high proclivity to use SM for improving learning. Students’ proclivity to use SM was not significantly correlated with their knowledge of use (r=0.025) while age (β=-0.287) contributed to their proclivity to use SM. Students are more willing to use SM for improved learning outcomes in Oyo State, Nigeria. The government and policymakers should create guidelines and recommendations for educators on how to integrate social media platforms into their teaching methods to improve learning outcomes.

Background: A survey to identify factors affecting the cooperation of children with autism spectrum disorder (ASD) in Indonesia is crucial for enhancing this group’s dental care, oral health, and overall quality of life. However, limited culturally relevant instruments hinder such research. Purpose: This study aims to determine the essential domain needed to design a questionnaire instrument that can predict the cooperativity of children with ASD during dental procedures. Methods: Based on the literature and existing questionnaires, the newly developed questionnaire underwent forward–back translation, before being thoroughly reviewed by an expert committee. The response format, content, and question clarity were evaluated. A cross-sectional study with 30 parents of children with ASD was randomly conducted to test the questionnaire. The validity of each question was measured by the Pearson product-moment correlation coefficient, while its reliability was assessed by Cronbach’s alpha. Results: Each question within the domain showed varying degrees of validity: reading ability (r = 0.658), daily communication (r = 0.541), involvement in social activity (r = 0.360), daily self-care ability (r = 0.506), emotional status (r = 0.426), sensory responsiveness (r = 0.615), language comprehension (r = 0.362), and permission to be touched on the head at a barbershop (r = 0.458). The questions were found to be reliable (Cronbach’s alpha, r = 0.645 > 0.306). Conclusion: As prediction tools for assessing the cooperativity of children with ASD during dental procedures, the questionnaire should include the following items: communication and reading abilities, daily self-care, social activity, emotional status, sensory responsiveness and permission to be touched on the head at a barbershop.

Understanding Peer Sexual Norms, Attitudes, and Pressure: Correlates of Risky Sexual Behaviours among Secondary School Adolescents in Anambra State, Nigeria

Aims: Sexual behaviour initiation often takes place throughout adolescence and is typically linked to engaging in unprotected sexual practices and other high-risk sexual behaviours. This research investigated the correlation between peer sexual behaviour, sexual attitudes, pressure to engage in sexual activity, and sexual risk behaviours among secondary school adolescents in Anambra State. Methodology: The study was carried out with a correlational research approach. The research included 1,200 individuals from a population of 19,048 SS2 teenagers in public secondary schools. Cronbach's Alpha statistics were used to evaluate the internal consistency of three scales: the Brief Sexual Attitudes Scale (BSAS), the Pressure to Have Sex Questionnaire (PTHSQ), and the modified Sexual Risk Behaviour Scale (SRBS). The reliability coefficients for the Adolescent Sexual Behaviour Index (ASBI) were 0.86, 0.96, and 0.80, respectively. The reliability index of the ASBI was determined using Kuder Richardson statistics, resulting in a coefficient of 0.86. The data was obtained by directly administering the instruments and processed using the Statistical Package for Social Sciences (SPSS). Pearson Product Moment Correlation is a statistical measure that quantifies the strength and direction of the linear relationship between two variables. Coefficients were used to address the research enquiries, while the null hypotheses were examined using a t-test to determine significant association. Results: The results indicated a weak positive association between the sexual conduct of peers, sexual attitudes, and pressure to engage in sexual activity, and sexual risk behaviours among secondary school teenagers in Anambra State. Furthermore, the findings demonstrated a notable association between these variables and the sexual risk behaviours of secondary school adolescents in Anambra State. Conclusion: Based on these data, it was determined that there is a weak positive link between peer sexual behaviour, sexual attitude, peer pressure to engage in sexual activity, and unsafe sexual behaviours among secondary school teenagers in Anambra State. Given this information, it is advisable for school administrators to establish health initiatives aimed at assisting young people in adopting enduring sexual habits that promote their overall health and well-being. These practices should also aim to minimise their susceptibility to HIV and other sexually transmitted diseases.

Examining posttraumatic growth among Turkish family caregivers of cancer patients

Cancer is a deadly disease that affects millions of people worldwide and is a source of great difficulty, stress, and trauma not only for patients but also for their caregivers. The physical and emotional suffering that patients experience by patients can lead their caregivers to cope with constant anxiety, sadness, and uncertainty. Moreover, during the cancer treatment process, caregivers must make a great effort to meet the needs of patients and support them. This situation may negatively affect the quality of life and psychological health of cancer patients’ caregivers and may lead them to experience trauma. The aim of this cross-sectional study was to examine posttraumatic growth’s relationship with age, the transformative power of suffering, and hope in family caregivers of cancer patients. Participants consisted of 314 Turkish family caregivers of cancer patients (73.2% women; Mage = 39.89 years) selected by using convenience sampling method. Participants answered a data collection tool consisting of a demographic information form, the Posttraumatic Growth Inventory, Trait Hope Scale, and Transformative Power of Suffering Scale. Data were analyzed using descriptive statistics, the Pearson product-moment correlation coefficient analysis, simple mediation analysis, and moderated mediation analysis. The results of this study revealed that hope mediated the association between the transformative power of suffering and posttraumatic growth in family caregivers of cancer patients, whereas age moderated this relationship. Psychosocial support programs for cancer caregivers could benefit from incorporating interventions that explore the transformative potential of suffering and cultivate hope. Tailoring these interventions to address the specific needs of different age groups may enhance their effectiveness. Future researchers should investigate the factors associated with posttraumatic growth in caregivers across diverse cultures, age ranges, and cancer diagnoses.

Research on signal denoising algorithm based on ICEEMDAN eddy current detection

This study addresses the challenges of non-stationarity and significant background noise interference in eddy current detection signals by proposing a noise reduction method based on Improved Complete Ensemble Empirical Mode Decomposition with Adapted Noise (ICEEMDAN). The process commences with the signal being decomposed using Improved Complete Ensemble Empirical Mode Decomposition with Adapted Noise into a finite number of Intrinsic Mode Functions (IMFs). Each Intrinsic Mode Function is then evaluated for the presence of high-frequency noise using a Power Spectral Density (PSD) analysis. The high-frequency noise present in the Intrinsic Mode Functions is then reduced using Normalized Least Mean Squares (NLMS) before being reconstructed with the remaining Intrinsic Mode Functions. Subsequently, the reconstructed signals are subjected to another round of decomposition using Improved Complete Ensemble Empirical Mode Decomposition with Adapted Noise. The Pearson Product Moment Correlation Coefficient (PPMCC) is utilised to calculate the correlation between the Intrinsic Mode Functions within each layer, retaining those with a strong correlation to further attenuate noise. Ultimately, the local maxima judgement method selectively amplifies defect signals by assessing changes in peak and valley degrees, thereby improving the signal-to-noise ratio of the eddy current detection signal. The experimental results demonstrate that, in comparison to the use of only the conventional Improved Complete Ensemble Empirical Mode Decomposition with Adapted Noise and Normalized Least Mean Squares denoising methods, the proposed method increases the Signal-to-Noise Ratio (SNR) by 1.08 dB and 2.31 dB, respectively, and decreases the Mean Square Error (MSE) by 106.9 and 223.9, respectively. The false alarm rate for stainless steel welded tubes with defects is 1.4%, while the false alarm rate for stainless steel welded tubes without defects is 0.4%.

Is Selfie Taking Behavior Beneficial for the Mental Wellbeing of Young Adults?

The purpose of the present study was to investigate whether selfie taking behavior is beneficial for the mental well-being of young adults and to investigate the difference in psychological issues among people who like to take selfies and those who don’t. Two hundred participants were recruited in this study following convenience sampling technique. The Depression scale, Bangla version of the Self- Esteem scale, and Bangla version of the General Health Questionnaire -12 were used as instruments in this study. This study used t-test and Pearson Product Moment Correlation for analyzing data. Results showed that selfie taking behavior is negatively correlated with depression score which means more selfie taking leads to fewer depressive symptoms. It was also found that people who like to take selfies and post selfies more on social media have shown less depressive symptoms, better self-esteem and less psychological distress than the people who don’t like to take and post selfies. The results can be taken to indicate that people who like to take or post selfies more exhibit a better state of mental well-being and less psychological issues. Dhaka Univ. J. Biol.
