Getting to know Kelvin
Authors: Lagmay Alfredo Mahar Francisco
Published: December 2023

During Pinatubo’s eruption in 1991, a tall whitebearded man stood in the Mayor’s office of Olongapo. Surrounded by a throng of terrified men and sacs of foreign mail, he spoke in English and Ilocano, advising everyone to remain calm as Pinatubo vented its fury. D This was the first time I saw Kelvin Rodolfo. He was 54 years of age and I was 25. That single encounter with Kelvin forever changed my life from a Geologist to a Volcanologist. He did not do anything out of his ordinary self to make this impression. He was just there when it mattered, and simply spoke his science in his usual passionate way. It took a decade before I really came to know him, when he became an adjunct faculty member at the National Institute of Geological Sciences, University of the Philippines; his office merely three rooms away. He would visit U.P. annually for a few months to work with Dr. Siringan and some other colleagues in the department. As I regarded him as an iconic figure, he seemed difficult to approach. But an Oxfam funded research work at the lake of Pinatubo changed all that, enabling me to work with Kelvin and break through his intimidating facade. It turns out he is a gentle, humorous and sensitive man.

PERILAKU INDIVIDU DALAM PRAKTIK SENJANGAN ANGGARAN: APAKAH KARENA FAKTOR TEKANAN ATASAN (OBEDIENCE PRESSURE) DAN LOCUS OF CONTROL?
Authors: Umyana Ayu
Published: December 2023

Praktik senjangan anggaran dapat timbul karena adanya masalah agensi dalam hubungan antara manajemen dengan pihak prinsipal yang menimbulkan adanya konflik kepentingan. Penelitian ini berusaha memberikan bukti empiris apakah tekanan ketaatan (obedience pressure) dan locus of control menjadi salah faktor yang mendorong seseorang melakukan senjangan anggaran. Obedience pressure merupakan tekanan yang datang dari pihak atasan kepada staf atau bawahan. Locus of Control dimana dalam kondisi dibawah tekanan-tekanan tertentu individu akan kehilangan kemampuan untuk menentukan nasib mereka sendiri dan cenderung berperilaku mengikuti perintah yang diberikan oleh atasan dan bahkan perilaku tersebut bertentangan dengan nilai-nilai dan keyakinan individu itu sendiri. Penelitian ini menggunakan desain eksperimen 2x2 between-subject untuk menguji tingkat ketaatan dan locus of control seseorang dalam praktik senjangan anggaran. Hasil penelitian ini menyimpulkan bahwa tekanan kepatuhan/ketaatan yang datang dari atasan dapat mempengaruhi perilaku seseorang untuk melakukan praktik senjangan anggaran. Seseorang yang tidak mendapat tekanan dari atasan menunjukkan 2,2 kali lebih mungkin untuk tidak melakukan senjangan anggaran. Sementara itu, seseorang yang mendapat tekanan dari atasan 0,454 kali lebih mungkin untuk tidak melakukan senjangan anggaran. Sementara itu, locus of control tidak mempengaruhi perilaku seseorang untuk melakukan senjangan anggaran. Jika dibandingkan antara seseorang dengan locus of control internal dan seseorang dengan locus of control eksternal, individu dengan locus of control eksternal 1,2 kali lebih mungkin untuk melakukan senjangan anggaran dibanding individu dengan locus of control internal. Seseorang dengan locus of control eksternal 0,820 kali lebih mungkin untuk tidak melakukan senjangan anggaran dibanding individu dengan locus of control internal.

Work life balance merupakan prinsip hidup seimbang antara kehidupan pribadi dan pekerjaan. Sebagai pegawai, seorang Aparatur Sipil Negara juga penting untuk menerapkan prinsip work life balance. Aparatur sipil negara wajib mengabdikan diri kepada negara dan rakyat Indonesia, siap ditempatkan dimana saja, siap dimutasi kapanpun dan dimanapun. Dalam pengabdiannya, Aparatur Sipil Negara juga diberikan hak-hak, salah satu hak umum yang dimiliki seorang Aparatur Sipil Negara adalah mendapatkan hak cuti tahunan. Penelitian ini bertujuan untuk melihat bagaimana penerapan work life balance di sektor publik dengan meninjau kembali implementasi atas pemberian cuti tahunan dan pola mutasi pegawai di sektor publik. Adapun metode yang digunakan dalam penelitian ini adalah scoping review/ literatur reviu. Hasil penelitian menemukan bahwa pemberian hak cuti tahunan dan pelaksanaan mutasi pegawai di sektor publik belum ideal, diantaranya persetujuan cuti tahunan yang masih cukup sulit didapatkan oleh para Aparatur Sipil Negara dan pola mutasi yang masih berdasarkan seniority system dan spoiled system. Hasil penelitian ini diharapkan menjadi bahan masukan bagi para pengambil kebijakan dalam menyusun dan mengkaji ulang peraturan yang berkaitan dengan hak cuti dan mutasi Aparatur Sipil Negara.

Challenges of Imaging Obese Patients in General Radiography: A Qualitative Systematic Review to Guide the Training and Practice in Zambia
Authors: Bwanga Osward , Bwalya Mubanga
Published: December 2023

Background: Obese patients are increasingly being referred for medical imaging examinations across the world. Obese patients require a modified standard of care to compensate for challenges caused by both technical and psychological issues related to their weight and body habitus. There have been research studies conducted on this issue, but no systematic review has brought the findings of these studies together to inform training and practice.

 Aim: This study was aimed at synthesising primary studies on the challenges faced by radiographers and radiography students in imaging obese patients to guide the training and practice in Zambia.

Methods: This qualitative systematic review was conducted using the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) guidelines. Two databases (PubMed and ScienceDirect) were systematically searched to identify relevant literature. This was supplemented by other sources: radiography journals, grey literature, and cited references. Data from the included studies were assessed for quality, extracted, and synthesised using thematic analysis.

Results: Five studies were identified and included in this review. Following data analysis, four themes related to challenges faced in imaging obese patients in general radiography emerged: difficulties in communicating without causing psychosocial distress, manual handling risks, limitation of the equipment, and difficulties in positioning and determining the exposure factors for diagnostic radiographic images.

 Conclusion: This review provides an in-depth understanding of the challenges faced by radiographers and radiography students in imaging obese patients. Strategies to enhance radiography training and practice have been identified to help educators and radiographers.
The association of Primary biliary cholangitis and Graves’ disease coupled with management challenges: a case report of a 36-year-old black Zambian female patient.
Authors: Mpisa Sydney , Sinkala Edford , Kawana Wamundila , Kamanga Brown
Published: December 2023

The occurrence of other autoimmune conditions in primary biliary cholangitis (PBC) patients is documented in literature and thyroid disease is such an example. Such cases are however rarely seen in the African setting and particularly in Zambia. Here we report a case of a 36-year-old black Zambian female patient who was diagnosed with PBC in 2014 at the University Teaching Hospital(UTH), Lusaka, Zambia. She was lost to follow-up until November 2020 when she presented with a flare of PBC. During the flare the patient reported a 2-weeks history of pruritus, fatigue, passing dark urine and pale stools, coupled with progressive weight loss. Examination revealed moist skin, scleral jaundice, generalised scratch marks, wasting with a body mass index (BMI) of 15kg/m2, a small goitre with a bruit heard over it and fine tremors. She did not have proptosis, finger clubbing or cervical lymphadenopathy or pretibial myxoedema. File review showed no prior goitre. Ultrasound of the neck confirmed the homogenous thyroid gland with increased vascularity. Blood tests revealed a suppressed thyroid stimulating hormone (TSH) (<0.005Uiu/ml) elevated free triiodothyronine (FT3) (10.9pmol/l) and elevated free thyroxine (FT4) (53.4pmol/l). TSH receptor antibodies were also elevated. The clinical features and blood tests led to the confirmation of Graves’ disease in a patient with PBC. Our patient was subsequently started on carbimazole, propranolol and continued ursodeoxycholic acid with great clinical response to treatment of both the PBC and Graves’ disease.

Our patient managed to gain weight within six months of commencement of Graves’ hyperthyroidism treatment, with her BMI improving to normal, at 22.6 Kg/m2. One year into her treatment she developed agranulocytosis likely from the carbimazole which was subsequently stopped resulting in her thyroid hormones going up again. The patient could not take propylthiouracil (PTU) in view of the liver disease as such radio-active iodine (which is not readily available) was the only feasible option.

Our case report contributes to the body of knowledge that PBC tends to coexist with autoimmune thyroid disease and should be looked out for with a high index of suspicion especially in patients with PBC who report weight loss despite doing well on PBC therapy.  We also seek to highlight the challenges in management and follow up of such patients in low resource setting. Although PBC is not so common in Black Africans, it should be suspected in patients who present with cholestatic jaundice especially in young female patients.

Authors: Chongo Billiat , Ngulube Chese , Mwansa Marjorie , Sashi Dominic , Mwiinga Fair Banji
Published: December 2023

Introduction: People with Osteoarthritis (OA) of the hip and knee have difficulties in performing basic activities of daily living. These problems arise from disturbed biomechanics, pain and loss of range of motion. Both pain and stiffness prevent deep knee flexion, a movement that is important in the use of both the toilet and the bathing facilities. The aim of this study was to determine the challenges faced by patients with osteoarthritis of the hip and knee in using their bathrooms in Lusaka, Zambia.

Methods: A cross sectional, descriptive quantitative study was done. The study was conducted at the University Teaching Hospital in the Department of Physiotherapy. Fifty six participants with hip or knee osteoarthritis were recruited in the study. Portions of the ICF were used to determine the level of difficulty in using both the bathtub for bathing and the toilet. A visual analogue scale and manual goniometer were used to measure the intensity of pain and range of motion respectively. Data were analysed using SPSS version 25.0. Chi Square test was used to determine if there was a relationship between severity of pain and the ranges of motion in the hip and knee at the significance level of 0.05.

Results: Participants in this study had a mean age of 53.39 years (SD=9.210). Majority were females (79%) and 21% males. The participants had mild problems with (52%, n=29) followed by moderate problems with bathing (32%, n=18). More than half of the participants had moderate problems (55% while a few (7%) had severe problems with toileting. During bathing and toileting, 80% and 62% of the participants experienced moderate to severe pain in the knee and hip respectively. There were significant associations between the severity of pain and the ranges of motion in hip flexion, hip extension and knee flexion (P = 0.01, 0.001 and 0.02).

Conclusion: Patients with OA of the knee and the hip have moderate to severe challenges with bathing and toileting. Pain may be the main factor contributing to the challenges in bathing and toileting. Physiotherapy needs to take the bathing and toileting facilities into account when managing patients with OA of the knee and hip.
Effects of angiotensin receptor blockers and angiotensin-converting enzyme inhibitors on respiratory Mucin-5ac, Mucin-C5b and Forkhead box protein-A2 of a hamster tracheal mucosa.
Authors: Mubbunu Lumamba , Mwaanga Edwell , Hang'ombe Bernard , Siziya Seter , Simukoko Humphrey

Background: Respiratory mucosal surface is continuously exposed to inhaled pathogens, and a protective layer of secreted mucus acts as the first line of defense against infection through a mechanism called mucociliary clearance. Mucus hypersecretion can negatively affect mucociliary clearance. Although ARBs and ACEIs are associated with induction of cough and angioedema as their side effects, no studies were found that show the effects of these drugs on Mucin-5ac, Mucin-5b, and Forkhead box protein A2. Mucin-5ac and mucin-5b are the main mucins in respiratory mucus and the viscoelasticity properties of respiratory mucus depends on them.
Methods: This study used a hamster as an animal model to investigate the effects of ARB and ACEI on respiratory mucin-5ac, mucin-5b, and Forkhead box protein A2. Enalapril and Losartan were used as representative drugs for ACEIs and ARBs, respectively. The concentrations of mucin-5ac, mucin-5b, and Forkhead box protein a2 were measured using ELISA. Dunnet’s t-test was used to analyze the results.
Results: Enalapril and Losartan increased mucin-5ac and mucin-5b, but the increase was not significant compared to the control (p > 0.05). However, enalapril and Losartan decreased the concentration of Forkhead box protein a2, but the decrease was not significant compared to the control (p > 0.05).
Conclusions: The study found that, administration of enalapril or losartan did not have a significant effect on the concentration of Mucin-5ac, Mucin-5b, and Forkhead box protein A2. Therefore, the administration of these drugs will not reduce mucociliary clearance of the respiratory tract through the impairment of mucus production.

Control of the Hyperbolic Ill-posed Cauchy \\[6pt]Problem by Controllability
Authors: B. Guel Bylli André , Tao Sadou , Sawadogo Somdouda
Published: December 2023

The main purpose of this paper is the control of the hyperbolic ill-posed Cauchy problem. To do this, we adapt to the present case the controllability method previously introduced in the stationary case (Bylli 2023). So we interpret the problem as an inverse problem, and therefore a controllability problem. This point of view induces a regularization method that makes it possible, on the one hand, to characterize the existence of a regular solution to the problem. On the other hand, this method makes it possible to obtain a singular optimality system for the optimal control, without using any additional assumption, such as that of non-vacuity of the interior of the sets of admissible controls, an assumption that many analyses have had to use.

Recent Ornithological Literature from the Caribbean: 2017
Authors: Latta Steven C.
Published: December 2023

An annual feature of the Journal of Caribbean Ornithology, thiscolumn alerts readers to recent ornithological literature fromthe Caribbean basin that has appeared elsewhere. Most of thesearticles appeared in 2017, although a few that we missed in 2016are also summarized below. We would also like to include anyunpublished theses or other reports that may be difficult to findin more universally available abstract services. We invite readersof the Journal of Caribbean Ornithology to alert our compiler,Steven Latta, to other articles that should be highlighted in thissection. Our hope is that by providing these summaries we willincrease the exchange of knowledge among Caribbean ornithologistsand conservationists.

Human resources (HR) is a crucial aspect that determines the effectiveness of an organization. Therefore, organizations need to pay attention to the turnover rate within their companies. This research aims to determine the effects of job stress and organizational climate on turnover intention, mediated by job satisfaction. The sample of this study consists of 200 employees from a housing development company scattered across the city of Bandar Lampung. Data collection was carried out through a questionnaire using probability sampling techniques and processed using Structural Equation Modeling (SEM) with the assistance of AMOS software. The results of the study show that job stress has a positive and significant impact on the turnover of employees in the housing development company in Bandar Lampung, while organizational climate has a negative and significant impact on employee turnover. Job satisfaction mediates the effects of job stress on turnover intention, and job satisfaction also mediates the effects of organizational climate on turnover intention. Companies can offer mental well-being support programs, open communication channels for all employees, periodically evaluate the workload of employees, and conduct interviews with employees regarding the primary reasons for the desire to leave the company. Purpose: The aim of this research is to determine the effects of job stress and organizational climate on turnover intention, mediated by job satisfaction. Patients and methods: The sample of this research consists of 135 employees from a housing development company in Bandar Lampung. Data collection was carried out through a questionnaire based on the simple random sampling method, with the sampling technique being probability sampling. Results: The results of the study show that job stress has a positive and significant impact on the turnover of employees in the housing development company in Bandar Lampung, while organizational climate has a negative and significant impact on employee turnover. Job satisfaction mediates the influence of job stress on turnover intention, and job satisfaction also mediates the effects of organizational climate on turnover intention. Conclusion: Companies can offer mental well-being support programs, open communication channels for all employees, periodically evaluate the workload of employees, and conduct interviews with employees regarding the primary reasons for the desire to leave the company.
