Patterns and Surgical Outcomes of Primary Brain Tumors Managed at a Tertiary Hospital in Arusha, Tanzania: a Cross-sectional Analysis

Purpose: The epidemiology of brain tumors varies globally between different countries and there is observed poor outcomes in lower- and middle-income countries. Our aim is to analyze the clinicopathological pattern of intracranial tumors in our setting and their post-surgical outcomes. Methods: This is a retrospective study. Data was obtained from clinical records of patients with intracranial tumors treated at our neurosurgery unit between 2019 and 2020. Only patients with primary brain tumors who underwent surgical intervention were included. Analysis was done to identify factors associated with patient outcomes (mortality/survival and performance status). Results: 39 patients with primary brain tumors underwent surgery (adults 72.8%, males 53.8%, mean age 35.8years). Gliomas (46.2%) comprised the most common tumor diagnosis overall and craniopharyngiomas were the most common tumors in pediatric patients (27.3%). Most patients (83.3%) had a poor performance status before surgery. Gross tumor resection (25.6%) was low and few patients (31.4%) underwent adjuvant therapy. 30-day mortality rate (10.3%) and one year mortality rate (46.2%) were high. Pediatric patients had a much worse outcome (46.2% mortality rate compared to 25% in adults, and 80% with poor performance status) as did males (38.1% mortality rate compared to 27.8% in females). Gliomas accounted for majority (69.2%) of the deaths. Conclusion: Delayed presentation and poor access to adjuvant therapies are important contributors of the high mortality and abandonment of treatment. Inadequate long-term follow-up is a hinderance to optimal neurooncological care in our setting.
Burnout among the Directors of the Internal Medicine Residency Training Program in Saudi Arabia

Overview: Burnout and depression symptoms are extremely common among internal medicine physicians including program directors. Burnout is defined as work-related syndrome characterized by emotional exhaustion, depersonalization and a sense of reduced personal accomplishment. Nearly 50% of physicians experience burnout. Hence, this increasing problem has a major impact on a director’s physical and mental health, thereby not only causing danger to the physician’s health but also affecting a patient’s health and putting a strain on the healthcare system. Methods: This was a descriptive, cross-sectional study conducted from March 2018 to October 2019. There are more than 60 training centers offering internal medicine programs all around the Kingdom of Saudi Arabia. This study was approved by the Quality Committee, which follows the Scientific Council for Internal Medicine at Saudi Commission of Health Specialties. All participants were informed about the study objectives and confidentiality of survey re -sponses, and they provided informed consent. Results: Among 40 program directors who participat-ed in this survey, (85%) were stressed out. Moreover, 27.5% expressed lack of support from the hospital’s administration, 23.1% claimed that the department head interfered with the training process, 30% were frustrated with their uncooperative colleagues, and 82.5% denied receiving any financial benefit other than training allowance. Finally, 95% were satisfied with their performance as program directors. Conclusion: Similar to other physician groups, program directors experience burnout. Nevertheless, more studies should be conducted to better understand stress and its possible causes. Further, such investigations can help identify the reasons behind the lack of support, in addition to protection of program director’s encouragement.
Exploring Adversity And The Potential For Growth Among Female Ironman Competitors

Over the years, only a handful of researchers have systematically examined the experiences of female triathletes (e.g. Cronan & Scott, 2008). Therefore, the purpose of the current study was to explore adversity and the potential for growth among female Ironman competitors. By looking at empowerment, athletic potential, and growth through adversity, the goal was to gain a clearer understanding of how female athletes utilize adversity to grow into empowered athletes and achieve their athletic potential. Seven female Ironman athletes were interviewed using Interpretive Phenomenological Analysis (IPA); IPA is centered on exploring peoples’ lived experiences, the meaning of their experiences, and how they make sense of their experiences (Smith, 2011). Participants averaged 49.8 years of age and had been involved in triathlons for roughly 13 years. All participants self-identified as middleto upper-class and Christian; in addition, six self-identified as Caucasian and one as Asian. Six participants were married, six had children, and one was widowed. Results revealed three main themes (a) experiences of adversity; (b) lessons learned; and (c) warrior spirit. As more women enter the Ironman world, continued discussion pertaining to what growth through adversity means as well as what empowerment means is important (Lewis & Ridge, 2005; McGannon, Curtin, Schinke, & Schweinbenz, 2012; Miller & Brown, 2005).
WITH LARGE DEFORMATIONS VIA QUASI-CONFORMAL MAPS

Registration, which aims to ﬁnd an optimal one-to-one correspondence between diﬀerent data, is an important problem in various ﬁelds. This problem is especially challenging when large deformations occur. In this paper, we present a novel algorithm to obtain diﬀeomorphic image or surface registrations with large deformations via quasi-conformal maps. The basic idea is to minimize an energy functional involving a Beltrami coeﬃcient term, which measures the distortion of the quasi-conformal map. The Beltrami coeﬃcient eﬀectively controls the bijectivity and smoothness of the registration. Using the proposed algorithm, landmark-matching diﬀeomorphic (1-1 and onto) registrations between images or surfaces can be eﬀectively obtained, even with a large deformation or large number of landmark constraints. The proposed algorithm can also be extended to a hybrid registration model, called Q-Fibra , which combines landmark and intensity (such as image intensity or surface curvature) information to obtain a more accurate registration. Experiments have been carried out on both synthetic and real data. Results demonstrate the eﬃcacy of the proposed algorithm to obtain diﬀeomorphic registrations between images or surfaces.
Teachers' Feedback: Influence on First Year Social Studies Students' Motivation towards New Normal Learning in Leyte Normal University

Motivation serves as an integral part of a student's learning process. It is considered as the driving force of students in achieving good quality performances and results from the academic tasks brought by the school as it gives students the opportunity to learn efficiently and effectively. One great factor that could influence students’ motivation is through the feedback that teachers give to their students. Teachers’ feedback is vital as it lets students adjust to their best learning by reflecting on their progress and strategies. However, because of the Covid-19 pandemic, new normal learning has been implemented which became a great challenge to the teaching and learning process and imposed issues on feedback and motivation. This qualitative research is a descriptive case study which aims to know what feedback teachers provide to students and describe how this feedback influences their motivation to learn in the new educational setting. Results have indicated that teachers’ feedback, specifically positive feedback, enhances student motivation to learn in the new normal. On the contrary, when there is a negative or no feedback at all given, students feel demotivated and would resort to self-motivation. These findings suggest that teachers’ feedback has a direct influence on students’ motivation to learn depending on the quality of the feedback given. With this premise, teachers and the institution must develop effective ways to improve teachers’ skills in delivering efficient feedback practices as it would help in enhancing students’ academic performance and improves students’ motivation to learn.

THE IMPACT OF AUDIT QUALITY ON THE FINANCIAL PERFOMANCE OF LISTED COMPANIES IN RUSSIA

: This research is aimed to aid in the development of a more efficient and professional function and image of internal audit in Russian enterprises. Shareholders should recognize the function of the internal audit in a company that safeguards their interests as one of the most essential management control systems. Corporate management should find ways to make Internal Audit a totally autonomous managerial function that will make it more efficient. Management might improve the company's performance by following recommendations. In Russia where businesses want to acquire reputation among local and global investors, such research on the relationship between audit quality and financial performance are quite significant. The purpose of this study was to assess experimentally the financial performance of companies in Russia for audit quality. First, we reviewed the relevant literature in this work. Then, a description of data and methodology explanation was given. To conclude, the results and the analysis were presented and the thoughts were concluded.
Does the Self‐Myofascial Release Affect the Activity of Selected Lower Limb Muscles of Soccer Players?

Abstract Myofascial therapy has already become one of the basic forms of treatment of the locomotor system. One form of the therapy is Self-Myofascial Release, in which external force is applied to the body with the help of special rollers (foam rolling, FR). The aim of the study was to investigate the direct effect of Self-Myofascial Release of hamstring muscles using a foam roller on the bioelectric activity of selected muscles (biceps femoris and gluteus maximus) during squats. The study involved 40 male soccer players, who were randomly divided into two groups: experimental and control. The tests used did not show significant differences in the analyzed variables before the experiment (baseline measurement p > 0.05), while significant intergroup differences appeared for subsequent measurements, both for reference MVC values (p < 0.01 - for % gluteus maximus MVC, p < 0.001 - for % biceps femoris MVC) and for raw EMG values (p < 0.01 gluteus maximus and p < 0.001 - for % 0.0001 for biceps femoris). The use of self-myofascial release within the hamstring muscles leads to changes in the electrical potential of the muscles of the lower limb.
Revealing the mystery of persistent smell loss in Long COVID patients

COVID-19 is hopefully approaching its end in many countries as herd immunity develops and weaker strains of SARS-CoV-2 dominate. However, a new concern occurs over the long-term effects of COVID-19, collectively called “Long COVID”, as some symptoms of the nervous system last even after patients recover from COVID-19. This review focuses on studies of anosmia, i.e., impairment of smell, which is the most common sensory defect during the disease course and is caused by olfactory dysfunctions. It remains mysterious how the olfactory functions are affected since the virus can't invade olfactory receptor neurons. We describe several leading hypotheses about the mystery in hope to provide insights into the pathophysiology and treatment strategies for anosmia.
SIMULATION OF HEAT TRANSFER AND METAL FLOW IN WIRE-BASED ELECTRO BEAM ADDITIVE MANUFACTURING

The urgency of mathematical model development for wire-based electron-beam additive manufacturing process analysis is shown. The procedure of solving heat equation for metal in the solid phase and the Navier-Stokes equations in the liquid phase, based on the use of the finite-difference method and the predictor-corrector procedure is described. An algorithm for numerical approximation of free melt surface motion, using the concept of the volume of fluid (VOF), is described as well. A numerical algorithm for surface tension force calculating is proposed. The model described above was realized as a program in the Microsoft Visual Studio environment. Series of computational experiments were carried out to calculate metal flow during deposition with the use of 316L steel wire. The results of experiments are compared with experimental data.
ORGANIZATIONAL INNOVATION STRATEGIES: THE VALUE CO-CREATION STRATEGY (VCS) MODEL

Challenged with market competition, firms can effectively connect innovative research and development, marketing activities, and design resources by using a value co-creation method. After a pilot case study was completed and preliminary models were established, this study proceeded with 2 questionnaire surveys. The first questionnaire survey investigated the co-creation strategies of firms in marketing, innovation, and design. A total of 278 valid questionnaires were recovered. A second survey was conducted 1.5 years after new product launch to identify the NPD performance of the 278 sample firms. Eventu-ally, a total of 242 valid questionnaires were recovered. The main findings in this study are presented as follows: a) A value co-creation strategy (VCS) conceptual model was proposed in response to innovation, marketing, and design co-creation strategies and NPD performance. b) A partial least squares method was used to examine the VCS model. The results show favorable fitness between the VCS model and questionnaire survey observation data, indicating that the VCS model has application value. c) The innovation, marketing, and design co-creation strategies of an enterprise affected NPD performance. In addition, through comprehensive co-creation strategies, these strategies and approaches affected NPD performance. The co-creation strategies in the VCS model were independent variables and mediating variables to NPD performance. Firms can reference the approaches proposed in this study to efficiently develop products and services on the basis of their organizational resources and market advantages and continually win market shares.
On the Effects and Boundaries of Awe and Humor Appeals for Pro-Environmental Engagement

Awe, a self-transcendent emotion often triggered by vast nature panoramas, is likely to stimulate pro-environmental action. We examined whether appealing to awe could promote perceived risk of climate change, support for low-carbon policies, and intentions to perform pro-environmental behaviors. Given conversations around comedy as a strategy for communicating climate change, we also tested whether appealing to humor, another positive emotional experience, could have similar effects. In a preregistered experiment with a national sample of U.S. adults, we found that awe appeals increased all outcomes measured. The parody-based humor appeals strengthened belief in climate change and perceived risk. These findings demonstrate awe-inspiring messages can increase several pro-environmental outcomes and parody can increase belief-oriented outcomes. For outcomes where the effects of the awe appeals depended on individuals’ political affiliation, effects were strongest for Republicans.
Innovation and profitability following antitrust intervention against a dominant platform: The wild, wild west?

Drawing on research on competitive repositioning, we examine how an antitrust intervention against a dominant technology platform prompts changes in competition in an ecosystem, in turn influencing complementor and platform performance. In particular, we argue that sparking new opportunities for complementors by weakening a dominant platform’s market power can drive increases in innovation but dampen the viability of the platform ecosystem by reducing profits. Using a novel dataset on enterprise infrastructure software from 1998 to 2004 and a difference-in-differences design using matching and synthetic controls, we examine the relationship between the U.S. Department of Justice’s antitrust intervention against Microsoft (dominant enterprise server platform) and subsequent innovation and profitability by infrastructure applications firms (enterprise complementors). The data show that innovation—measured by citation-weighted patents—is increased following the antitrust intervention. However, profitability is reduced. The counterintuitive finding is that antitrust intervention benefits ecosystems in the form of innovation but may threaten the financial viability of some of the very firms it is meant to help. Our results contribute to understanding links between competition and innovation, and the opportunities and threats related to dominant platforms in their ecosystems.
ORGANISATIONAL CLIMATE AND ITS EFFECT ON EMPLOYEES' JOB SATISFACTION AND COMMITMENT

The need to embrace the rising changes in the employment market place has made organisations to strive for committed employees and the absence of such breeds deficiency in job satisfaction and employees' commitment. The study was aimed at examining the effects of organisational climate and its effects on employee's job satisfaction and commitment of selected tertiary institutions in North Central, Nigeria. This study adopted a primary means of data gathering and a close ended questionnaire was designed to gather information. The study population was 3184 and a sample of 314 was taken out of a population with the aid of Krejcie and Morgan (1970) Table of Sample. Hence, this study revealed that organisational climate does have significant effect on job satisfaction and employees' commitment to job. Additionally, this study concludes that organisational climate through the adoption of reward, teamwork, training and development and autonomy has positive effects on commitment of academic staff. Lastly, this study recommends that universities in Nigeria especially in the North Central must ensure that adequate attention is given to organisational climate through reward, teamwork, training and development and autonomy to academic staff in order for employees to achieve impactful job satisfaction and commitment which will in turn affect the overall performance of the Institutions.
Ethnic diversity and firm performance: Evidence from India

We examine if the financial performance of firms in India depends on the level of ethnic diversity in the state or district in which they operate. Thus, using data on 1,199 listed firms in the materials, industrial and information technology sectors in India, we examine the impact of ethnic diversity on various measures of firm financial performance. Based on indices of fractionalization calculated for 15 states and 74 districts in which these firms operate, we find evidence of negative effects of ethnic diversity on firm performance. These results are robust to endogeneity and alternative ways of measuring diversity.
INTERNATIONAL ISLAMIC ECONOMIC SYSTEM CONFERENCE (I- i ECONS 2021) Sustainable Growth Rate for Malaysian Public-Listed Shariah-Compliant Companies: Does Financing Behaviour Matter?

We aim to investigate the firm factors affecting the sustainable growth rate by segregating the different situations on financing behaviour of Malaysian public-listed Shariah-compliant companies. We use Structural Equation Model (SEM) of the STATA software for the analysis of 181 Shariah compliant companies in Malaysia over the period of 2007 to 2016. Based on the results, target leverage and target dividend policy exists in Malaysian Public-listed Shariah-compliant firms. After identifying the matrix financing behaviour of capital structure and dividend policy, this research then continues the empirical research and found that profitability is significantly positive relationship with sustainable growth rate for all types of matrix financing behaviour. While, firm size is significantly positive with sustainable growth rate only in Matrix 1 (over-levered and over-paying) and 4 (under-levered and under-paying). Moreover, company’s efficiency is significantly positive with sustainable growth rate in Matric 3 (over-levered and under-paying) but significantly negative in Matrix 1(over-levered and over-paying) and 2 (under-levered and over-paying). Capital structure and dividend policy are negatively significant relationship with sustainable growth rate in Matrix 3 (over-levered and under-paying) and 4 (under-levered and under-paying). This results will assist management teams in terms of which area should give priority to improve firm’s sustainable growth rate and make the firms successful in the future. This research provide new evidence concerning on matrix financing behaviour by applying the analysis using STATA software. In addition, the research provides additional knowledge in the existing literature by focusing on the issues of financing behaviour and sustainable growth rate in the context of Malaysian public-listed Shariah-compliant firms.
TRAINING SPECIFIC FUNCTIONAL, NEURAL AND HYPERTROPHIC 3 ADAPTATIONS TO EXPLOSIVE- VS. SUSTAINED-CONTRACTION STRENGTH 4 TRAINING 5 EXPLOSIVE- VS. SUSTAINED-CONTRACTION STRENGTH TRAINING

30 Training specificity is considered important for strength training, although the functional and 31 underpinning physiological adaptations to different types of training, including brief 32 explosive contractions, are poorly understood. This study compared the effects of 12-wks of 33 explosive-contraction (ECT, n =13) vs. sustained-contraction (SCT, n =16) strength training vs. 34 control (CON, n =14) on the functional, neural, hypertrophic, and intrinsic contractile 35 characteristics of healthy young men. Training involved 40 isometric repetitions (x3/wk): 36 contracting as fast and hard as possible for ~1 s (ECT); or gradually increasing to 75% of 37 maximum voluntary torque (MVT) before holding for 3 s (SCT). Torque and EMG during 38 maximum and explosive contractions, torque during evoked octet contractions, and total 39 quadriceps muscle volume (QUADS VOL ) were quantified pre- and post-training. MVT 40 increased more after SCT than EST (23 vs. 17%; effect size [ES]=0.69), with similar 41 increases in neural drive, but greater QUADS VOL changes after SCT (8.1 vs. 2.6%; ES=0.74). 42 ECT improved explosive torque at all time points (17-34%; 0.54≤ES≤0.76) due to increased 43 neural drive (17-28%), whereas only late-phase explosive torque (150 ms, +12%; ES=1.48) 44 and corresponding neural drive (18%) increased after SCT. Changes in evoked torque 45 indicated slowing of the contractile properties of the muscle-tendon unit after both training 46 interventions. These results showed training-specific functional changes that appeared to be 47 due to distinct neural and hypertrophic adaptations. ECT produced a wider range of 48 functional adaptations than SCT, and given the lesser demands of ECT this type of training 49 provides a highly efficient means of increasing function. 50 51 52 53
