The Influence of Customer Retention Practices on Performance of Micro and Small Agro-processing Enterprises in Tanzania
Authors: Nnko Eliakira 
Published: February 2023

Customer retention practices are considered as derivers to accelerate firm performance in highly competitive business environment. However, scanty literature exists on agro-processing MSEs in developing economies. This study was carried out in Dar es Salaam, Arusha and Morogoro regions to examine the relationship between customer retention practices and performance of agroprocessing micro and small enterprises (MSEs). The study employed quantitative research approach and a cross-sectional research design. Proportionate stratified sampling was used to select a sample of 302 MSEs. A self-administered questionnaire was used to collect data from these firms. Structural Equation Modelling (SEM) was used to analyse the relationship between customer retention practices and firm performance. Firm performance was found to be positive and significantly influenced by assessment to customers, analysis of competitors, response to customer needs, inter-functional coordination practices and employees behavioural practices. Business-supplier relational practices posited positive relationship with the firm performance. The findings suggest that customer retention practices are influential determinants of the performance. This implies that owner-managers of agro-processing MSEs who wish to improve the performance of their firms should put emphasis on understanding the needs of their customers, analyse the actions and behaviours of competitors, appropriately coordinate internal functions of their firms and manage employees behaviours towards customers to ensure sufficient response to needs of the customers, and they should maintain positive relationship with the suppliers of raw materials. Likewise, practitioners and policy makers should appreciate the role of customer retention practices when designing policies, trainings and support services for MSEs.
Single and Competitive Removal of Pb(II) in the Presence of Ni(II) using Polyacrylamide Grafted Rice Husk

Published: February 2023

In a quest to find efficient adsorbents for metal ions, studies on various adsorbents for metals have been of interest since the past several decades. The present study is focused on the removal of Pb (II) ions from aqueous solution using poly acrylamide grafted rice husk by batch studies. Industrial waste waters generally contain metals present as mixtures, therefore the effect of Ni (II) on the removal of Pb(II) from mixtures of Pb(II)+Ni(II) ions has also been investigated. The adsorbent has been prepared by the treatment of rice husk with acrylamide in the presence of N,N-methylene bis acrylamide and potassium persulphate. The adsorbent has been characterised by infrared spectral studies. Maximum adsorption obtained is 93% at pH 5, metal ion concentration 300mg/L in 180mins at 298K. Isotherm analyses show that both Langmuir and Freundlich isotherm models are best obeyed. The process is endothermic and spontaneous in nature and follows pseudo first order kinetics. Intraparticle diffusion also occurs but is not the rate determining step. Application of Langmuir competitive model for the binary system shows that adsorption of Pb(II) has been supressed by presence of Ni(II) ions. Studies suggest that the adsorbent is effective and can find industrial applicability.

Authors: Salawu F. B. , Otori A. A. , Mohammed K. , Mathew J. T. 
Published: February 2023

The subject of this study was to optimize the transesterification parameters of biodiesel produced from sword bean (C. gladiate) using Response Surface Methodology (RSM). Four transesterification parameters (Reaction temperature 55 0C, Catalyst concentration 0.4 wt%, Methanol to oil ratio 4:1 and reaction time 60 min) were optimized. Data obtained revealed that the optimum reaction conditions for the transesterification of C. gladiata seed oil resulted in 92.88% biodiesel yield. Multiple regression analysis produced a quadratic polynomial equation for methylester and a linear relationship was recorded between the observed and predicted value (R2 = 0.9647) with a significant molar ratio and temperature. The interaction terms of methanol to oil, molar ratio and temperature with reaction time exhibited a positive effect on the methylester yield. The response surface methodology was found to be a suitable technique for optimizing transesterification process and producing biodiesel that meets the ASTM standard.
Circulation of the Silesian Political Elite - Case Study
Authors: Cukier-Syguła Monika 
Published: February 2023

This paper is aimed to investigate the exchange index of the Silesian political elite in cities with county rights from the 2002 election through five elections until 2018. The author’s deliberations on the political elite exchange are based on the political elite circulation theory presented by Vilfredo Pareto. The key research question to be answered in this paper is: What is the exchange index of the local political elite’s representatives in cities with county rights in the Silesian province (PL “województwo” [voivodeship] – a local government administration unit in Poland).
A regression analysis was carried out to test the influence of the year of the term of office and city on the political elite’s exchange level. The list of councillors was transformed into a database using a Python algorithm. Further data operations (diagram plotting, model calculation) were performed in the R 4.0.5 statistical environment (R Core Team, 2020). The analyses proved that the observed values of the political elite exchange index were close to the mean or distributed homogenously around it. Chorzów was the only exception for which the political elite exchange index was significantly lower than the mean for each year. The mean index of “political elite exchange” was higher in 2002 than in other years, while the expected means of 2006, 2010, and 2014 differ insignificantly. The analyses revealed a relatively stable composition of the elites. The summary contains conclusions and recommendations.

Published: February 2023

Pendahuluan: Satpam dengan kerja gilir berisiko mengalami insomnia. Berdasarkan studi oleh Didi Purwanto tahun 2005 pada pekerja pabrik semen Citeureup–Bogor, prevalensi insomnia mencakup 48,1% pada pekerja gilir dan mencapai hampir dua kali lebih tinggi dibandingkan pekerja non gilir. Tujuan penelitian ini adalah untuk mengetahui prevalensi insomnia dan faktor–faktor yang meningkatkan risiko kejadian insomnia pada satpam dengan kerja gilir di PT. X.
Metode: Desain penelitian menggunakan potong lintang yang dianalisis secara analitik, melibatkan 107 satpam dengan kerja gilir. Pengambilan data menggunakan beberapa kuesioner, yaitu kuesioner Sleep Hygiene Index, kuesioner Stress Diagnostic Survey, kuesioner Insomnia Rating Scale-KSPBJ, serta wawancara menggunakan instrumen MINI.
Hasil: Prevalensi insomnia pada satpam dengan kerja gilir di PT. X adalah 81,9%. Hasil analisis statistik menunjukkan sikap higiene tidur buruk meningkatkan risiko terjadinya insomnia hampir 10 kali lebih tinggi dibandingkan dengan sikap higiene tidur baik (OR=9,820, 95%IK=1,185–81,413). Usia lebih tua, masa kerja lebih lama, pola kerja gilir iregular dan stres kerja sedang-tinggi tidak terbukti meningkatkan risiko kejadian insomnia pada satpam dengan kerja gilir (p>0,05).
Diskusi: Saran bagi satpam yang menjalani kerja gilir yaitu dapat menerapkan sikap higiene tidur dengan baik. Bagi manajemen PT. X, disarankan penyuluhan berkala setiap tiga bulan sekali mengenai gangguan kesehatan akibat kerja gilir terutama insomnia dan evaluasi kesehatan pada satpam yang mengalami insomnia setiap satu hingga tiga bulan sekali.

Published: February 2023

The aims of this study are: 1) to identify and analyze the implementation of bsps program policies in poverty alleviation in tibawa district; 2) to find out what are the factors that determine the success of implementing the bsps program policy in poverty alleviation in tibawa district
This study uses a research conducted using a qualitative approach while the type of research used in this thesis research is qualitative descriptive research.
The results of this study indicate that: 1) the implementation of the bsps program policy in poverty reduction in tibawa district has not run optimally. In measuring the success of the implementation of the bsps policy, it can be seen from 3 indicators, namely: a) it is seen that the planning has been carried out optimally; b) the implementation of the bsps program has been running but is not yet optimal. One of the non-optimal programs of this bsps is the absence of a clear soup. In addition, the availability of materials also affects the implementation of the bsps program. The availability of materials provided by suppliers or material stores is limited or does not match the demand for goods needed by the recipient community of the bsps program. In addition, the price of materials that are suddenly expensive so that they are not in accordance with the drpb and rab that have been made by the recipients of the bsps program; c) judging from the supervision process has been carried out properly. Supervision is carried out in a preventive and repressive manner. Preventive supervision is carried out before the start of an activity or before the occurrence of financial expenditures for bsps assistance. Meanwhile, repressive supervision is carried out by evaluating financial and operational accountability report documents. This inadequacy can be seen from the fact that there are still some people who do not fully understand and utilize the bsps assistance funds according to their designation; 2) the factors that determine the implementation of the bsps program policy in poverty reduction in tibawa district consist of resources, communication, and disposition
Early and delayed suture adjustments after adjustable suture strabismus surgery: a randomized controlled trial
Authors: Abdelmonem Ahmed Adel , Awadein Ahmed , Genidy Mahmoud Mohamed M , Abdelhalim Ahmed Shawkat , Abdelaziz Sahar Torky A 
Published: February 2023

Background: Adjustable sutures increase the success rate of strabismus surgery. However, the optimal timing of postoperative suture adjustment remains controversial. This trial was aimed at comparing the surgical outcomes and pain scores of early or 2 – 4 h and delayed or 24 h postoperative suture adjustment in adult patients undergoing strabismus surgery.
Methods: An open-label, prospective, randomized, comparative interventional study was performed in consecutive adult patients scheduled for eye muscle surgery. Patients were randomized into two groups: the early group, with suture adjustment 2 – 4 h postoperatively, and the delayed group, with suture adjustment 24 h postoperatively. Subjective pain scores during the adjustment were also analyzed. The angles of misalignment at 1 and 3 months and the success rate at 3 months postoperatively were compared.
Results: Forty-five (90%) patients completed the follow-up, including 23 (92%) in the early adjustment group and 22 (88%) in the delayed adjustment group, with a mean (standard deviation) age of 25.6 (9.5) years and a male-to-female ratio of 46.7:53.3. Thirty patients (66.7%) had exotropia, and 15 (33.3%) patients had esotropia. Both groups had comparable baseline characteristics (all P > 0.05). The mean pain scores during adjustment did not differ significantly between groups (P > 0.05). The postoperative angles of alignment were comparable between the groups before suture adjustment and at the 1- and 3-month follow-ups (all P > 0.05). The success rate in the early adjustment group was slightly higher (87.0% versus 63.6%), but the difference was not statistically significant (P > 0.05). The success rate was comparable between the groups in patients with esotropia or exotropia (both P > 0.05).
Conclusions: Although the early adjustment group had a slightly higher success rate, the difference was not significant. Both groups had comparable subjective pain scores during adjustment. Future clinical trials should be performed different time intervals for postoperative suture adjustment, and subjective and objective outcomes, such as diplopia and stereopsis, should be compared between patients with a first strabismus surgery and those who underwent reoperation. This could better resolve the persistent controversy related to the optimal time for suture adjustment.

Published: February 2023

Background: In patients with type 2 diabetes mellitus, the development of diabetic retinopathy (DR) correlates positively with elevated serum chemerin levels. This study was aimed at investigating the probable association between the serum chemerin level and the development of DR in patients with type 1 diabetes mellitus (T1DM).
Methods: In this cross-sectional study, we included Egyptians and classified them into four groups: group 1, including healthy individuals; group 2, including patients with T1DM without DR; group 3, including patients with T1DM with non-proliferative DR (NPDR); and group 4, including patients with T1DM with proliferative DR (PDR). The assessment included best-corrected distance visual acuity assessment, slit-lamp biomicroscopy, funduscopy, fundus fluorescein angiography, and macular ocular coherence tomography. Fasting blood samples were obtained from all participants to measure serum chemerin, glycated hemoglobin (HbA1c), total cholesterol, triglyceride, and creatinine levels. Serum chemerin levels were compared among the groups, and their correlations with age, duration of diabetes, HbA1c, total cholesterol, triglyceride, and creatinine levels were analyzed.
Results: We recruited 209 participants, including 46 healthy individuals in group 1, 52 patients (T1DM and no DR) in group 2, 61 patients (T1DM and NPDR) in group 3, and 50 patients (T1DM and PDR) in group 4, with comparable mean ages and sex ratios among groups. The diabetes duration, body mass index, HbA1c, total cholesterol, triglyceride, and serum chemerin levels differed significantly among the groups (all P < 0.001), whereas the creatinine level did not (P > 0.05). The serum chemerin level was significantly higher in group 4 than in groups 3 and 2, in group 3 than in group 2, and in groups 3 and 4 than in group 1 (all P < 0.001). However, it was comparable between groups 1 and 2 (P > 0.05). It correlated with the duration of T1DM and HbA1c, total cholesterol, triglyceride, and creatinine levels but not with age.
Conclusions: Patients with T1DM with DR showed higher serum chemerin levels than those with T1DM without DR or healthy individuals. Serum chemerin levels were higher in those with PDR than in those with NPDR. Thus, serum chemerin levels are a potential biomarker of the development and severity of DR in patients with T1DM. Nevertheless, future diagnostic accuracy studies are required to confirm these potential applications.
