A Study of the Relationship between the Quality of Social Support System and Drug Use among Street Children in Starehe Sub-County, Nairobi County Kenya

The study aimed at examining the relationship between the quality of the social support system and drug use among street children in Starehe Sub-County, Nairobi County Kenya. The specific objectives of the study were to: explore the relationship between psychosocial health and drug use among street children and the relationship between the quality of social support system and drug use among street children in Starehe Sub-County, Nairobi County Kenya. This study adopted the correlational research design. Data were collected from 100 street children. These were sampled using cluster and simple random sampling techniques from a target population of 30,000 in Starehe Sub-County of Nairobi County. In addition, data was collected from purposively sampled four officials from the Starehe Children's Office, eight officials of NGO/FBO operating in the sub-county, 1 sub-county administrator, and 4 ward administrators from the Sub-County. The qualitative data collected using questionnaires were analyzed using descriptive statistics like mean, percentage, and frequencies, as well as inferential statistics such as Pearson correlation and regression analysis. The findings obtained were presented using charts and tables. The qualitative data collected using interviews were analyzed thematically. The findings were then presented in prose. The findings show that the independent variables are psychosocial health and quality of social support. Pearson correlation showed that there was a significant relationship between drug use and all the independent variables (psychosocial health, r=0.503, p<0.05 and quality of social support system, r=0.538, p<0.05. The findings show that the measures put in place to enhance the mental health of street children made had significant influences on their drug use. Strengthening the existing social support systems meant that street children could get the support needed to steer them away from drug use. The study recommends that it is important to promote the social support systems in the Starehe sub-county. There is also a need to provide street children with homes to reduce exposure to stressful conditions that could lead to mental health problems.
Optimization of Real Power Loss and Voltage Stability Index for Distribution Systems with Distributed Generation

Integrating Distributed Generation (DG) units into distribution systems can have an impact on the voltage profile, power flow, power losses, and voltage stability. In this paper, a new methodology for DG location and sizing are developed to minimize system losses and maximize voltage stability index (VSI). A proper allocation of DG has to be determined using the fuzzy ranking method to verify best compromised solutions and achieve maximum benefits. Synchronous machines are utilized and its power factor is optimally determined via genetic optimization to inject reactive power to decrease system losses and improve voltage profile and VSI. The Augmented Lagrangian Genetic Algorithm with nonlinear mixed-integer variables and Non-dominated Sorting Genetic Algorithm have been implemented to solve both single/multi-objective function optimization problems. For proposed methodology effectiveness verification, it is tested on 33-bus and 69-bus radial distribution systems then compared with previous works.
Characteristics of dementia family caregivers who use paid professional in-home respite care

ABSTRACT Caring for a person living with dementia (PLWD) can be challenging, making support services like respite important. Of the types of respite, research on paid professional in-home care specific to family caregivers of PLWD is limited. This study aimed to identify characteristics of dementia caregivers using paid in-home respite. A self-administered online survey (N = 98) examined use of in-home respite. Measures assessed depressive symptoms, burden, and self-rated health. Analyses included descriptive statistics and qualitative coding. Most respondents utilized weekly schedules of in-home respite with a moderate correlation between dependency and hours of respite. Caregivers’ self-reported average health, depressive symptoms, and mild-to-moderate burden. The majority of users had lowered perceived stress, were satisfied with services, and indicated the importance of in-home respite during a pandemic. Future research should assess changes in use of paid in-home respite services and overall landscape of respite options for dementia caregivers.
A History of the Relationship Between Interest Rate and Profit Rate in Heterodox Approaches

Abstract This article seeks to understand, compare, discuss and systematize the theories on the causal relationship between the rate of interest and the rate of profit, as proposed by various authors, while highlighting their similarities and differences. One group of authors asserts that the rate of interest determines the rate of profit, and thus the distribution of income, while a second argues that once the distribution is determined, it is the rate of profit that governs the rate of interest. This attempt to analyze and systematize the main approaches forms a significant first step in understanding contemporary finance.
Cirsilineol Inhibits the Proliferation of Human Prostate Cancer Cells by Inducing Reactive Oxygen Species (ROS)-Mediated Apoptosis

Cirsilineol has been reported to exhibit anticancer effects against several human cancer cell lines. The present study was designed to evaluate the anticancer effects of cirsilineol against the human DU-145 prostate cancer cells. The results showed that cirsilineol suppressed the proliferation of DU-145 cancer cells in a dose-dependent manner with minimal cytotoxic effects against the normal cells. The IC50 of cirsilineol was found to be 7 μM and 110 μM against prostate cancer DU-145 and normal HPrEC prostate cells, respectively. Acridine orange and ethidium bromide (AO/EB) staining showed that cirsilineol induced apoptosis in DU-145 prostate cancer cells. The Annexin V/PI staining further confirmed the induction of apoptosis in DU-145 cells. The western blot analysis showed that cirsilineol suppressed the expression of Bax and upregulated the expression of Bcl-2 in prostate cancer DU-145 cells. Moreover, cirsilineol caused a dose-dependent increase in reactive oxygen species (ROS) levels in prostate cancer. Wound healing and Transwell assays showed that cirsilineol inhibits migration and invasion of DU-145 prostate cancer cells. Summing up, the results suggest that cirsilineol suppresses the proliferation of prostate cancer cells and may prove to be a beneficial lead molecule for the development of chemotherapy for prostate cancer.
Effectiveness of psychodynamic-oriented counselling intervention in reducing psychological distress in university students seeking help

ABSTRACT The outcome of a psychodynamic counselling intervention for students seeking psychological help at a university counselling centre in Italy was evaluated by examining its effect on clinical symptoms of the students. The intervention consisted of four counselling sessions and a later three-month follow-up session. The sample (N = 160) was drawn from a population of 360 university students. An in-treatment group (n = 86) was compared to a waiting-list comparison group (n = 74). Post-test measures were administered one month after baseline for each group. The psychodynamic counselling intervention was found to be a valid method to reduce psychopathological symptoms and to improve psychological adjustment among university students.
Pregnancy outcomes and contraceptive use in women with rheumatoid arthritis

Rheumatoid arthritis (RA) is a common chronic autoimmune disorder that has a female predominance and commonly affects women of childbearing age, it is shown to remit during pregnancy in most studies and improve in about half of the patients when assessed with objective disease activity measurements. To assess the pregnancy outcomes in women with rheumatoid arthritis prior and after diagnosis and compare it with women with no chronic illness. To evaluate contraceptive practices and correlated contraceptive method efficacy with use of concomitant rheumatic medications. (Methotrexate, leflunomide). A total of 100 female patients diagnosed with rheumatoid arthritis according to ACR/EULAR 2010 classification criteria were compared with apparently healthy female controls matching in age in this case- control study. Data was collected by questionnaires and interview. The questionnaires included demographic data and pregnancy outcomes, mode of delivery, contraceptive methods used by patients with the current use of methotrexate and leflunomide. The mean age for the patients and controls were 38.4+5.1 and 36.7+4.5 years respectively. The live births significantly decreased in female patients with rheumatoid arthritis in compare with controls and before diagnosis (p 0.010, p 0.002 respectively).
The Consecutive 3-month Length Increment to Predict Early Linear Growth Failure

AIM: This study aimed to assess the consecutive 3-month length increment thresholds, by the first 6 months, to predict stunted at the age of 6 months. METHODS: We analyzed data from the Bogor Longitudinal Study on Child Growth and Development in West Java, Indonesia. A total of 635 free of stunting at birth children were analyzed in this study. Early linear growth faltering, as the dependent variable, was the stunted at 6 months of age. The four thresholds of the consecutive 3-month length increment were considered in predicting stunted at the age of 6 months. The thresholds were a consecutive 3-month length increment below 25th percentile, 15th percentile, and 5th percentile of the WHO Child Growth Velocity Standard. The 4th threshold was generated from the Bogor Longitudinal Study sample and determined using receiver operating characteristic analysis. The sensitivity, specificity, PPV, and NPV of the thresholds were calculated. RESULTS: Among the thresholds, the 25th percentile of the WHO Child Growth Velocity Standard generates the highest sensitivity. The ability of the 25th percentile threshold to correctly identify children who had stunting at 6 months of age is 56.7%. However, the children whose experience a consecutive 3-month length increment below 15th percentile had highest risk to become stunted at the age of 6 months, adjusted by sex, birthweight, and birth length. CONCLUSION: A consecutive 3-month length increment could be beneficial as a tool in identifying infants at high risk of early linear growth failure in stunted prevalent population.

Peritoneal dialysis after failed kidney transplantation; a case series with review of the literature

Kidney transplantation is a definite treatment for end-stage renal disease (ESRD). However, management of allograft dysfunction has remained a major challenge and some patients return to dialysis after renal transplantation. Studies showed that peritoneal dialysis (PD) results in a higher chance of survival and a lower risk of delayed allograft dysfunction compared to hemodialysis (HD). For this reason, this study explored the initiation of PD in six patients with renal allograft dysfunction in Tabriz Imam Reza hospital (referral PD center). This case reported the results of PD and incremental PD among these patients with failed kidney transplantation. Creatinine and hemoglobin levels, duration of starting PD, PD exchange, PD modality, immunosuppressive drugs mortality rate and urine volume were evaluated during the study. In conclusion, although re-transplantation is a gold standard therapy in failed kidney transplant patients, PD or incremental PD could be a suitable and home-based modality for preserving renal function and urine output in these patients.
A Comparison Between Neoadjuvant Chemotherapy and Neoadjuvant Chemoradiotherapy in Treating Esophageal Carcinoma: A Study at a Tertiary Care Cancer Center in Suburban India

Background and objective Esophageal carcinoma remains a disease associated with high mortality rates among patients even after receiving treatment. Management with surgery alone offers a five-year survival of only 20%. Hence adjuvant and neoadjuvant therapies were instituted to treat this condition along with surgery. Neoadjuvant chemoradiotherapy (NACRT) followed by surgery is currently the standard of care. Neoadjuvant chemotherapy (NACT) is also recommended by some authors as a method of adequate care. There is a scarcity of studies in the literature comparing NACRT with NACT. In light of this, we employed the criteria of pathological response as a primary endpoint to compare the effectiveness of NACT and NACRT in treating esophageal carcinoma. Materials and methods A total of 50 patients with esophageal cancer having Eastern Cooperative Oncology Group (ECOG) scores 0-2 with cancer stages cT2-T4a, cN0-N1, and cM0 were enrolled. The patients were further classified into two groups of 25 each. While one group received chemotherapy using inj. paclitaxel and carboplatin (NACT group), the other was managed with inj paclitaxel and carboplatin as well as 42 Gy of fractionated irradiation (NACRT group). Six weeks after the last dose of radiation or three weeks after chemotherapy, they were evaluated and offered transthoracic esophagectomy (TTE). Results Squamous cell carcinoma was found in 39 (78%) cases and 11 (22%) cases had adenocarcinoma. Pathologically complete or near-complete responses were seen in 42% of patients in the NACRT group and 22% in the NACT group. Conclusion While NACT and NACRT are both effective therapies for esophageal cancers, NACRT offers better tumor regression compared to NACT. Given the higher rates of complete or near-complete response in the NACRT group, NACRT is likely to offer higher overall survival rates than NACT.
Coherent Structures in Taylor-Couette Flow: Experimental Investigation

Taylor-Couette flow is defined as the flow confined between two coaxial cylinders which can rotate independently. Several different flow states can be observed in the gap between the cylinders by changing the rotation speeds and the rotating directions of the cylinders. The aim of this thesis is to investigate the previously reported change of torque values with the rotation speeds of the cylinders and to study its relation to coherent turbulent flow structures. The flow structures are investigated using tomographic PIV, which is a fully volumetric measurement method that resolves all three velocity components. Different flow states, and their contribution to the Reynolds stresses are revealed. Initially, the Taylor-Couette setup was used to investigate the spatial resolution of tomographic PIV, by exploiting the fact that the power input to the system, as determined from the torque measurements and the cylinder rotation speed, is balanced by the viscous dissipation rate, which can be computed using the measured velocities. Next, time-resolved tomographic PIV measurements were performed at fully turbulent flow to demonstrate the capability of the measurement system and the flow geometry to study dynamic events in turbulence. Turbulent flow with an approximately zero mean velocity was created by rotating the cylinders in opposite directions with the same wall velocities. Using this idea, the observation times of the flow structures could be increased by an order of magnitude as compared to similar studies in turbulent boundary layers. Finally, the connection between turbulent flow structures and the change of the torque was made by using tomographic PIV. In order to compute the contribution of the large and the smaller-scale structures to the torque, the instantaneous flow was decomposed into the large and the smaller-scale motions by filtering. The Reynolds stresses associated with these structures indicate that the orientational change of the structures may be the mechanism responsible for the reported change of the torque scaling.
REMARKS ON THE FRACTAL DIMENSION OF BI-SPACE GLOBAL AND EXPONENTIAL ATTRACTORS

Bi-spaces global and exponential attractors for the time continuous dynamical systems are considered and the bounds on their fractal dimension are discussed in the context of the smoothing properties of the system between ap- propriately chosen function spaces. A unifled analytic semigroup approach to abstract parabolic equations is described and applications to the sample prob- lems are given. Sunto. In questo lavoro sono considerate le nozioni di attrattori globali ed espo- nenziali \bi-spaces" per sistemi dinamici continui, e discusse limitazioni relative alla loro dimensione frattale in spazi di funzioni opportuni. Inoltre, viene pre- sentato un approccio uniflcato per lo studio di problemi parabolici astratti, nella teoria dei semigruppi analitici, ed alcuni esempi sono mostrati. 1. Introductory notes Attractors for the dynamical systems governed by partial difierential equations in inflnite dimensional Banach spaces have been considered by several authors within past few decades; see (3, 8, 11, 16, 18, 28, 1, 10, 12, 14, 21) and references therein. A general approach leading to the description of their topological dimension have essentially been developed, allowing to obtain much of the relevant information about the asymptotic behavior of the systems corresponding to a number of physical equations in both Hilbert and Banach function space setting. In this article we reconstruct the results of (1, 3, 11, 12) concerning the bi-spaces global and exponential attractors and provide simultaneously certain bounds on their fractal dimension, which are a straightforward consequence of the smoothing properties of the dynamical system acting between appropriately chosen function spaces. These mentioned properties are known to be typical for problems that fall into a class of abstract parabolic equations in Banach spaces. Since the latter class contains many relevant physical equations, it is reasonable to describe the speciflc 'dissipative and smoothing mechanism' that leads to the existence of the global and exponential attractors and provides the bounds on their fractal dimension within the unifled analytic semigroup approach of (17).
Traditional farmers’ pig trait preferences and awareness levels toward reproductive biotechnology application in Zambia

Objective: This study assessed traditional farmers’ preferences for indigenous pigs and their awareness levels toward reproductive biotechnology. Materials and Methods: This cross-sectional, descriptive study employed a mixed-methods concurrent triangulation design with a pragmatic approach. For quantitative data collection, a randomly selected sample size of 622 respondents was interviewed using a structured questionnaire. A semi-structured interview guide was used in seven focus group discussions (FGDs) for qualitative data. For quantitative data, descriptive statistics were used to find out how often something happened, and chi-square tests were used to look for relationships. For qualitative data, thematic analysis was used. Results: The majority (66.9%) of respondents were female, and they had largely (64.8%) attended a primary level of education. A slight majority (43.1%) of the respondents were 30–45 years old. Most respondents (65.1%) were low-income earners (below K500). Incidentally, the majority (74.1%) of respondents had low awareness of reproductive biotechnologies. Respondents’ awareness levels were associated with gender (p < 0.001), education (p < 0.001), income (p < 0.01), and not age (p > 0.05). With regard to trait preference, a total of seven indigenous pig traits were reportedly preferred, of which disease resistance (25.9%) and litter size (23.8%) were the most preferred. From FGDs, participants valued indigenous pigs, citing many preferred traits, of which disease resistance and litter size were the most emphasized traits. Some participants were aware of many reproductive biotechnologies and their perceived advantages. However, they were more familiar with artificial insemination, heat detection methods, and synchronization. Conclusions: The majority of respondents had low awareness of reproductive biotechnologies. Respondents’ awareness was associated with sociodemographic characteristics. The identified indigenous pig traits preferred by traditional farmers included adaptive and productive traits.
Needs Analysis of Problem-Based Learning Models in Boarding School: A Preliminary Research

This study aimed to find out how the description of the need for the development of problem-based learning models in Islamic boarding schools in the subjects of Social Sciences. This research is the initial phase in research and development (R & D) devoted to studying needs analysis with a qualitative approach. Data were collected using several instruments such as interviews, observations, and document analysis. Furthermore, the data were analyzed qualitatively by using content analysis techniques. The results showed the teachers and students at the As'adiyah Islamic Boarding School, especially MTs. As’adiyah Putra 1 Sengkang showed that students' ability in the field of Social Science studies still needed methods that we’re able to improve their learning achievement so that they could exceed the Minimum Completeness Criteria. They need innovation in the development of problem-based learning models to replace conventional methods that have been used in Islamic boarding schools.
Mining Large Open Online Learning Networks: Exploring Community Dynamics and Communities of Performance

Online learning communities are becoming increasingly popular as they are known to support collaborative dialogue and knowledge building. Previous studies have typically focused on small, closed learning communities from an individual, static, and aggregated perspective. This research aims to advance our understanding of open and large online learning networks by exploring and characterizing community level dynamics and communities of performance. To achieve this goal, we mined a large open online learning network of over 30,000 students and approximately one million posts. First, we analyzed overall community network development by building temporal social networks. Subsequently, we studied sub-community dynamics using community detection algorithms, and, following that, investigated the interaction between community dynamics and communities of performance using best colleague correlation and Kruskal-Wallis test. Results found that large open online learning communities begin with a very large network having numerous small sub-communities. These communities consist of students who are similar in performance with strong links. The overall network size gradually shrinks, as does the number of sub-communities, and these communities evolve over time for their membership formulation with students who are more different in performance with weaker ties. Theoretical, practical, and methodological implications are then discussed. This study pushed the online learning community research to examine large and open networks by taking a more community-based and dynamic view of investigation.
