Authors: Percy-Campbell Jessica , Buchan Jacob , Chu Charlene , Bianchi Andria , Hoey Jesse , S. Khan Shehroz
Published: September 2024

Smart Home Technologies (SHTs) have recently become popular for a variety of purposes, including healthcare, entertainment, and convenience, among others. While SHT manufacturers promise to provide a range of services relating to home security, health and wellness, automated domestic tasks, entertainment, and beyond, user perceptions vary widely in terms of benefits and drawbacks. Moreover, surveillance studies researchers have warned against normalizing technologies that may exacerbate uneven power dynamics between users and household members, marketing companies, insurance brokers, law enforcement, and others. Through an analysis of the interdisciplinary literature stemming from computer science and engineering, gerontology, the social sciences, and related fields, we explore the extent to which these potential risks and related concerns are reflected upon by smart home users. This scoping review aims to explore SHT user perceptions of privacy attitudes, the purposes of smart home surveillance, risks and benefits, and impacts on home safety. Through our review of sixty-eight relevant studies, we found that many smart home users reported satisfaction over perceived benefits such as an increased sense of safety and home security. Many others displayed limited understandings of data collection practices or expressed privacy concerns. Nonetheless, SHT usage prevailed among these users. Others report a perceived trade-off between privacy and other factors, such as convenience, and some may have resorted to privacy cynicism, a coping mechanism for dealing with ubiquitous surveillance. In order to better understand SHT adoption trends despite concerns, exploring the conflict between user perceptions of privacy, understanding of SHT data collection purposes, risks and benefits, and home safety, is essential.

Published: September 2024

For adult teeth with necrosis or apical periodontitis, regenerative endodontics provides a useful alternative to standard endodontic treatment. This review focuses on the pediatric endodontic considerations in the application of regenerative therapy for immature permanent teeth. A thorough literature search was conducted in the MEDLINE database using the keywords "pediatric, regenerative, therapy, endodontics, immature, permanent, and teeth" to find relevant publications published between 2017 and 2024. Additionally, Google Scholar was used to find and access pertinent scientific publications using the appropriate search terms. Various inclusion criteria were applied to select the articles for review. The selected articles were published between 2020 and 2024 and included discussions on several specific elements. Topics covered include the criteria for case selection for regenerative endodontics. Overall, the existing evidence indicates that using regenerative endodontic techniques to treat adult permanent teeth with apical periodontitis or necrosis may successfully lead to the resolution of apical translucencies and the absence of clinical signs and symptoms. With slight modifications to the clinical procedure, regenerative dentistry methods can be effectively applied to specific cases, such as those involving a small apical foramen, decreased blood supply, and a lack of growth factors. However, additional research is required to determine the optimal conditions for achieving successful treatment outcomes.

Objective: This study aimed to determine how common hepatobiliary complications were in children with sickle cell disease (SCD).
Methods: This was a retrospective descriptive study conducted at a single tertiary health care center, King Saud Medical City, Pediatric Hospital, Riyadh, from April 2023 to April 2024. Patient recruitment was done by reviewing the medical records. All pediatric patient cases under 14 years, with SCD in both genders were included without specifying any race or ethnic characteristic.
Results: A total of 143 patient cases with SCD were included in the hospital database. More than half of them were males. Hepatobiliary complications were observed in 19.5% of patients with SCD, cholelithiasis occurred in 26 (18.2%), cholangiopathy (bile duct stenosis) occurred in 3 (2.1%), and only one patient had acute hepatic sequestration (AHS). Biliary complication (cholelithiasis) was significantly associated with age and raised alanine aminotransferase (ALT) (p-value 0.042). Raised ALT was associated significantly with age, hemoglobin (Hb) level, and AHS. Total bilirubin > 2 mg/dl (> 34 micro mol/l) and direct bilirubin > 1 mg/dl (> 17 micro mol/l) were observed in 26.9% and 61.5% of patients who had cholelithiasis, respectively, low Hb in 46.2% and low platelet in 30.8%.
Conclusion: Hepatobiliary complications were observed in less than one-fifth of patients with SCD. The most common complication observed was cholelithiasis, rare complications were cholangiopathy and AHS.
A Review on the Impact of Teenage Pregnancy on Students’ Academic Performance
Authors: Ejuchegahi A. Angwaomaodoko
Published: September 2024

Teenage pregnancy has been reported to be rampant among secondary (high) school girls across the world, especially in developing countries. Low self-esteem, poor social-economic standards, poor parenting and peer influence, lack of age-appropriate sex education and poor knowledge of the apparent use of contraceptives are among the leading causes of teenage pregnancy. Teenage pregnancy has become a global concern as a result of its multifaceted consequences on the girl child and the general society. The primary aim of this study is to evaluate the impact of teenage pregnancy on the academic performance of students. Teenage pregnancy has overwhelming detrimental impacts on the academic achievement of the girl child. It has been listed as a major factor responsible for the majority of school dropouts by female students. It is characterized by low self-esteem, isolation and psychological effects, which may make the pregnant student skip classes and miss assignments, projects and exams, resulting in poor academic performance, which may ultimately lead to the student dropping out of school. The study recommends that deliberate efforts should be made by society to prevent teenage pregnancy, and if teenage students get pregnant, efforts should be made to improve their mental health and self-esteem. They should be given adequate support and not be isolated or thrown out of school.

Published: September 2024

To complete activities in any company setting effectively, monitoring and assessment systems are required. Despite having qualified personnel, a clear goal and vision, financial stability, and good governance processes, some local NGOs were having management issues or even risking closure. Recently, several initiatives have realized a greater need for monitoring and assessment. NGOs in developing nations, such as Kenya, face a variety of issues that have not yet been handled. This study was interested in ascertaining the influence of stakeholder involvement on the performance of monitoring and evaluation systems among NGOs operating in Turkana, Kenya's Loima Sub-County. The theory of change and open system theory served as the foundations of the research study. A descriptive study design with a survey approach involving questionnaire distribution was used. 97 participants were chosen at random from a pool of 129 people using the stratified random selection technique. Also, senior managers' interviews targeting 5 managers from the NGOs with over ten staff and a focus group discussion involving a participant from each of the 14 NGOs with the M&E staff provided more qualitative data. For validity, the study used the content validity index test whereby CVI of 0.7 and above indicated that the instrument items were valid. To assess the correctness and uniformity of the data, a Cronbach alpha test was performed; an accuracy of 0.7 indicated that the instruments used were adequate. All data-related operations, such as coding, sorting, tidying up, and editing, were carried out in order to perform statistical analysis using the SPSS program version 24. The study's findings demonstrated that the inclusion of stakeholders significantly increased the efficiency of M&E systems amongst NGOs operating in Loima (r=.685, p =.000). The research advises the management of the organization to set up safety precautions for M&E systems and to make sure they were strictly followed. To increase effectiveness, NGOs should think about including participants at every step of the project. The researcher recommends conducting additional research to determine the variables influencing the set-up of M&E Systems, even if it was not the main topic of this academic paper.

Authors: Abdiaziz Haji Bare  , Dr. Charles Nyamweya
Published: September 2024

In the present-day business environment, characterized by a faster communication system, managers of a firm cannot afford to engage in unethical practices because of the detrimental effect it can have on a firm but also the negative publicity that it will create and the consequent effect on the value. Ethical leadership provides a pragmatic methodology for influencing organizations' stakeholders, thus harvesting desirable and sustainable organizational outcomes. This is because ethical leaders demonstrate ethical conduct through their actions and also promote such ethical conduct among their followers. The study sought to examine the influence of ethical leadership on corporate governance in commercial banks in Nakuru East Sub-County, Kenya. The specific objectives of the study were to establish the influence of ethical human resource practices on corporate governance in commercial banks in Nakuru East Sub-County, Kenya; Cross-sectional research design was adopted. The target population comprised of all the 28 commercial banks in Nakuru East Sub-County. A sample of 12 banks was selected using stratified techniques, and then a sample of 108 bank employees will be sampled purposively. Data from the bank employees was collected using questionnaires. The researcher used the Statistical Package for Social Sciences (SPSS) software version 22 to measure the correlation analysis and highlight the relationship between the success of ethical leadership and corporate governance in the listed commercial banks in Nakuru East Sub-County, Nakuru. Descriptive statistics involved the use of absolute and relative (percentages) frequencies, measures of central tendency and dispersion (mean and standard deviation, respectively). Frequency tables and graphs were used to present the data for easy comparison. The study uncovered significant findings regarding the nexus between ethical leadership practices and corporate governance in commercial banks within Nakuru East Sub-county. Notably, ethical human resource practices were found to exert a substantial impact on historical governance. The regression analysis affirmed a robust relationship between ethical leadership variables and corporate governance. The study recommends targeted enhancements in training programs, policy revisions, and stakeholder engagement. These findings contribute valuable insights to the ongoing discourse on ethical leadership in the banking sector, offering practical implications for bolstering corporate governance in financial institutions.

Authors: Humphrey M. Njuki  , Elvis Kiano  , Lucy Rono
Published: September 2024

Against the background of the deleterious impacts of fossil fuel power generation, considerable attention has been given to developing renewable and clean sources of energy. Over the past few decades, geothermal energy has increased significantly across the world due to its low impact on climatic change. Although it is considered one of the most promising sources of renewable and clean energy, it is not exempt from environmental and social well-being drawbacks. In this study, we evaluate the external cost of electricity generated by geothermal power plants in Kenya. Both survey data and secondary data were used. The analysis was conducted using externality valuation and welfare maximization approaches, and the research hypotheses were tested using a negative binomial regression model. The results of both survey data and secondary data analysis show that geothermal power generation is attributed to negative environmental, public health, and socio-economic impacts as a result of emissions and sitting. Overall, the geothermal power generation annual external cost ($/2022) was determined to be $ 162,330.75 with the following distribution: Environmental at $ 90,905.22, Public health at $ 42,206.00, and Socio-economic at $ 29,219.53. Equally, the geothermal power generation marginal social cost ($/2022) was determined to be 0.02 $cents/kWh with the following distribution: Marginal Private Cost (MPC) at 0.02 $cents/kWh, and Marginal External Cost (MEC) at 0.000045 $cents/kWh. The established marginal social cost (MSC) (i.e. Σ MPC+MEC) was 0.02 ($cents/kWh). This is less than the established social marginal benefit (SMB) of 0.089 ($ cents/kWh); hence, we conclude that the burden of social welfare loss is insignificant, making geothermal power a sustainable energy source.

Authors: Lestari Juliana Tri , Sujiono Eko Hadi , Arsyad Muhammad
Published: September 2024

Planetary Boundary Layer (PBL) dipengaruhi oleh proses transfer momentum, energi, dan material antara PBL dengan lapisan permukaan. Variabel Surface fluxes meliputi Sensible heat flux (SHF) dan Latent heat flux (LHF) juga digunakan dalam mengukur tingkat transport pada proses ini. Namun, struktur PBL yang sangat kompleks menjadikan PBL sulit untuk diamati dan diidentifikasi. Fenomena Madden-Jullian Oscillation (MJO) di wilayah tropis turut andil pada kondisi atmosfer seperti pada lapisan PBL. Sehingga penelitian ini dilakukan untuk mendeskripsikan profil SHF/LHF dan PBL pada periode Madden-Julian Oscillation (MJO) kuat dan lemah di Makassar dan sekitarnya serta menganalisis hubungan antara keduanya. Penentuan ketinggian PBL dilakukan menggunakan metode Bulk Richardson Number (Rib) dan penentuan SHF dan LHF dengan metode bulk aerodinamic. SHF saat MJO kuat dan lemah pukul 12.00 UTC memiliki nilai lebih besar dibandingkan nilai pukul 00.00 UTC. Ketinggian rata-rata PBL lebih tinggi pukul 00.00 dibandingkan pukul 12.00 UTC dengan nilai sebesar 686,8 m dan 591,3 m berturut-turut. Rata-rata tahunan ketinggian PBL berkisar antara 470-1100 m. Rata-rata maksimum terjadi pada musim peralihan I (MAM) pukul 00.00 UTC, sedangkan minimumnya pada peralihan 2 (SON) pukul 12.00 UTC. Selain itu ketinggian PBL saat MJO kuat dan lemah tidak memiliki hubungan terhdap nilai SHF/LHF di Makassar dan sekitarnya.

Dampak perubahan iklim telah menjadi isu strategis yang mengancam kepentingan nasional dan lingkungan, terutama dalam konteks Tana Toraja di wilayah tropis Indonesia. Proses perubahan iklim yang dipengaruhi oleh faktor alamiah dan aktivitas manusia telah menyebabkan peningkatan suhu udara global dan anomali iklim. Risiko bencana alam, terutama terkait dengan curah hujan, seperti banjir, longsor, dan penyebaran penyakit, semakin meningkat. Pemerintah Indonesia perlu merancang strategi pembangunan daerah dengan rendah emisi gas rumah kaca dan mengendalikan deforestasi. Penelitian ini menggunakan metode kualitatif deskriptif dan data dari Stasiun Meteorologi Pongtiku Toraja selama 2000-2019 untuk menganalisis pola perubahan iklim dan dampak El-Nino Southern Oscillation (ENSO) di Tana Toraja. Temuan penelitian menunjukkan penurunan suhu udara rata-rata tahunan, peningkatan kelembapan udara, dan perubahan pola curah hujan menjadi tipe iklim ekuatorial. Dampak ENSO terhadap suhu udara, kelembapan, dan curah hujan bersifat variatif. Prediksi menunjukkan penurunan curah hujan, tetapi analisis gabungan menunjukkan kenaikan rata-rata 4.5% per tahun hingga 2029.

The Gorontalo fault is an active fault and is the main source of earthquakes in Gorontalo Province. A strong and destructive earthquake that has occurred in Gorontalo Province was on November 16, 2008 with a magnitude of 7.4 Mw. As one of the disaster mitigation efforts, a research was conducted to identify the type of Gorontalo fault. Data used from global gravity model plus (GGMplus) as free air anomaly data and shuttle radar topography mission (SRTM2Gravity) as modern terrain correction data that rely on full-scale topographic gravity data. These data are used to calculate the complete Bouguer anomaly data. The complete Bouguer anomaly data was subjected to spectrum analysis to obtain the depth of regional and residual anomalies and to separate regional and residual anomalies using the upward continuation method. On the residual anomaly, second vertical derivative (SVD) analysis was conducted to determine the type of Gorontalo fault. The inversion result of 3D model of gravity anomaly shows Gorontalo fault with medium and low density contrast. Based on the SVD analysis, the Gorontalo fault is a turun fault. This geological structure is considered to be a potential source of natural disasters in the Gorontalo region.

Published: September 2024

Percutaneous Coronary Intervention (PCI) is one of the essential methods for Acute Coronary Syndrome (ACS) treatment, but this procedure has serious complications. Early loading dose statin has a favorable prognostic impact on patients undergoing PCI. However, this effect is still unclear.Objective: To evaluated the effect of loading high-intensity statin on Major Adverse Cardiac Events (MACE) before PCI in patients with ACS. Methods: Randomized controlled trials were conducted using databases from  CENTRAL, PubMed, Science Direct, and British Medical Journal. Then, titles, abstracts, and full texts were screened using the inclusion criteria to filter out irrelevant studies. Quality assessments were undertaken using the Jadad scale, and the results were narratively synthesized and presented in tables. Results: Seven studies were included in this systematic review after screening 1037 records. Four studies demonstrated a statistically significant reduction in MACE in the groups that received loading dose atorvastatin or rosuvastatin before PCI, compared with the comparator groups (p < 0.05). Conclusion: Loading high-intensity statin before PCI seems to be highly effective in reducing MACE in patients with ACS.
