Workplace wellbeing among health care workers providing HIV services in primary care in Johannesburg: a mixed methods study

Background Burnout among Health Care workers (HCWs) impacts on provider-patient relations and quality of care. Anova Health Institute (Anova) is a large South African non-profit organization and PEPFAR/USAID implementing partner. We conducted a study among HCWs providing HIV-related services in primary care settings in Johannesburg, South Africa, to examine levels of burnout, understand factors affecting workplace wellbeing, and explore strategies to prevent burnout. Methods We used a sequential mixed-method approach. Data were collected between February and April 2022. The first phase consisted of a survey using the Maslach Burnout Inventory Human Services Survey (MBI-HSS) to measure levels of burnout. We then interviewed a subset of survey participants to understand the experiences that may affect wellbeing. We used descriptive statistics to quantify burnout rates for each MBI dimension (emotional exhaustion, personal accomplishment, and depersonalization). Qualitative data analysis was guided by the Job Demands-Resources Framework that explores the interactions between demands and resources in the workplace. Results Survey findings (n = 194) revealed that although depersonalization rates were low at 6%, 21% of participants had high emotional exhaustion and 24% reported low professional accomplishment. Less than half (41%, n = 80) had scores in the high category for any one of the three MBI-HSS dimensions. The MBI-HSS dimensions differed significantly by type of work and job title. Roving positions (HCW working in more than one health facility) were more likely to experience higher emotional exhaustion and lower professional accomplishment. Qualitative findings (n = 25) indicate that a number of job demands, including high workload, inadequate mental health support, and challenging relationships with stakeholders, had a negative effect on HCWs’ wellbeing. However, finding meaningfulness in their work, working as a team, and practicing autonomy were experienced as resources that reduced the negative effect of these demands. Conclusion While measured burnout syndrome rates were low, various experiences negatively impacted at least one in five HCW. We identified key resources that provided buffering against workplace stressors. We recommend that as well as addressing key drivers of burnout, access to these resources should be fostered, for example by strengthening interventions that offer recognition, and promoting team interactions through social activities and support groups.
An Overlapped Sub-array Hybrid Beamforming Architecture with Successive Interference Cancellation and Water-filling in Massive MIMO Systems

Over the years, wireless communication has significantly improved the data rate of mobile users. The key drive behind this success is the technological advancement in wireless communication. In the physical layer, hybrid beamforming has revolutionized the way signal reaches the user by constructively adding the signal at the destination thus improving the performance. Many researchers works have proposed different algorithms to solve for optimal hybrid beamforming. However, there is no single algorithm that can achieve both high spectral efficiency and energy efficiency at the same time. This work proposes a hybrid algorithm that combines successive interference cancellation and water filling and applies this algorithm in overlapped sub-array architecture (OSA). The former can successfully optimize for analog precoding in a subarray environment as it eliminates the interference between the successive sub-arrays. While the latter can allocate the power in each data stream proportionally, thus improving the spectral efficiency. The simulation results show that the proposed algorithm with OSA can achieve a near optimal performance in comparison to fully connected hybrid beamforming (FCH) and significantly larger performance in comparison to partially connected hybrid beamforming (PCH). Moreover, the proposed algorithm achieves 89.2% energy efficiency in comparison to PCH architecture. These results show that an OSA system with the proposed algorithm provides a better tradeoff between achieved spectral efficiency (SE) and energy efficiency (EE).
Analysis of Electrothermal Homogenization for the Fast and Accurate Modeling of Windings in Power Electronics Magnetic Components

This article deals with the electrothermal characterization of multi-turn windings in the magnetic components of power electronics (PEs) converters (inductors and transformers). The ever higher frequencies and smaller PE components demand the fast and accurate power loss computation for an optimal design accounting for severe electrothermal constraints. Homogenization techniques prove indispensable. Works on both electromagnetic and thermal homogenization exist but mainly consider both physics independently. We aim at studying the interaction of the strongly coupled systems when applying homogenization techniques. As test case, we consider a 2-D EI-planar inductor with two different multi-turn copper windings.
Breast Ultrasound Images Augmentation and Segmentation Using GAN with Identity Block and Modified U-Net 3+

One of the most prevalent diseases affecting women in recent years is breast cancer. Early breast cancer detection can help in the treatment, lower the infection risk, and worsen the results. This paper presents a hybrid approach for augmentation and segmenting breast cancer. The framework contains two main stages: augmentation and segmentation of ultrasound images. The augmentation of the ultrasounds is applied using generative adversarial networks (GAN) with nonlinear identity block, label smoothing, and a new loss function. The segmentation of the ultrasounds applied a modified U-Net 3+. The hybrid approach achieves efficient results in the segmentation and augmentation steps compared with the other available methods for the same task. The modified version of the GAN with the nonlinear identity block overcomes different types of modified GAN in the ultrasound augmentation process, such as speckle GAN, UltraGAN, and deep convolutional GAN. The modified U-Net 3+ also overcomes the different architectures of U-Nets in the segmentation process. The GAN with nonlinear identity blocks achieved an inception score of 14.32 and a Fréchet inception distance of 41.86 in the augmenting process. The GAN with identity achieves a smaller value in Fréchet inception distance (FID) and a bigger value in inception score; these results prove the model’s efficiency compared with other versions of GAN in the augmentation process. The modified U-Net 3+ architecture achieved a Dice Score of 95.49% and an Accuracy of 95.67%.

While the “ social determinants of health ” view compels us to explore how social structures shape health outcomes, it often ignores the role individual agency plays. In contrast, approaches that focus on individual choice and personal responsibility for health often overlook the in ﬂ uence of social structures. Amartya Sen ’ s “ capabilities ” framework and its derivative the “ health capabilities ” (HC) approach attempts to accommodate both points of view, acknowledging that individuals function under social conditions over which they have little control, while also acting as agents in their own health and well-being. This paper explores how economic, social, and cultural resources shape the health capability of people with diabetes, focusing speci ﬁ cally on dietary practices. Health capability and agency are central to dietary practices, while also being shaped by immediate and broader social conditions that can generate habits and a lifestyle that constrain dietary behaviors. From January 2011 to December 2012, we interviewed 45 people with diabetes from a primary care clinic in Ontario (Canada) to examine how their economic, social, and cultural resources combine to in ﬂ uence dietary practices relative to their condition. We classi ﬁ ed respondents into low, medium, and high resource groups based on economic circum-stances, and compared how economic resources, social relationships, health-related knowledge and values combine to enhance or weaken health capability and dietary management. Economic, social, and cultural resources conspired to undermine dietary management among most in the low resource group, whereas social in ﬂ uences signi ﬁ cantly in ﬂ uenced diet among many in the medium group. High resource respondents appeared most motivated to maintain a healthy diet, and also had the social and cultural resources to enable them to do so. Understanding the in ﬂ uence of all three types of resources is critical for constructing ways to enhance health capability, chronic disease self-management, and health. (cid:1) 2013 The Authors.

Workload Orchestration in Multi-Access Edge Computing Using Belief Rule-Based Approach

Multi-access Edge Computing (MEC) is a standard network architecture for edge computing, which is proposed to handle enormous computation demands from emerging resource-intensive and latency-sensitive applications and services as well as accommodate Quality of Service (QoS) requirements for ever-growing users through computation offloading. Since the demand of end-users is unknown in a rapidly changing dynamic environment, processing offloaded tasks in a non-optimal server can deteriorate QoS due to high latency and increasing task failures. In order to deal with such a challenge in MEC, a two-stage Belief Rule-Based (BRB) workload orchestrator is proposed to distribute the workload of end-users to optimum computing units, support strict QoS requirements, ensure efficient utilization of computational resources, minimize task failures, and reduce the overall service time. The proposed BRB workload orchestrator decides the optimal execution location for each offloaded task from User Equipment (UE) within the overall MEC architecture based on network conditions, computational resources, and task requirements. EdgeCloudSim simulator is used to conduct comprehensive simulation experiments for evaluating the performance of the proposed BRB orchestrator in contrast to four workload orchestration approaches from the literature with different types of applications. Based on the simulation experiments, the proposed workload orchestrator outperforms state-of-the-art workload orchestration approaches and ensures efficient utilization of computational resources while minimizing task failures and reducing the overall service time.
Shielding eﬀectiveness measurements and uncertainty estimation for textiles by a VNA-based free space transmission method

A free-space transmission method has been used for reliable shielding eﬀectiveness measurement of the easily available textile materials. Textiles with three diﬀerent yarn densities were studied for their shielding eﬀectiveness with the help of a vector network analyzer and laboratory calibrated two X-band horn antennas. The expressions of uncertainty estimation have been derived in accordance with the present free-space measurement setup for the calculated SE values. The measurements have shown that an electromagnetic energy can be maximum shielded up to 16.24 dB with measurement uncertainty less than 0.21 dB in 8.2 to 12.4 GHz range by a 160.85 μ m textile. Thus, a thin textile with a high density can have higher shielding and this property mainly depends on its intrinsic structure, frequency range and thickness. This study promises the potential applications of such materials as a very cost eﬀective shielding material at microwave frequencies with some modiﬁcations.
Comparative Study About Different Doses of Remimazolam in Short Laparoscopic Surgery: A Randomized Controlled Double-Blind Trial

Objective To study the efficacy and safety of different doses of remimazolam used for induction and maintenance in short laparoscopic surgery. Methods A randomized controlled trial was conducted between May 2021 and May 2022 on patients underwent laparoscopic surgery for 30 minutes to an hour. Based on the drug used and the infusion rate, included patients were allocated into the Low-group of remimazolam (using a constant infusion rate of 6.0 mg/kg/h for induction and the rate of 1 mg/kg/h for maintenance), the Median-group (9.0 mg/kg/h for induction, 2 mg/kg/h for maintenance), the High-group (12.0 mg/kg/h for induction, 3.0 mg/kg/h for maintenance), and the Propofol group. The postoperative extubation time was used as the primary outcome. Results A total of 192 patients were included in the study, with 47, 48, 48, and 49 patients in the Low-, Median-, High-, and Propofol group, respectively. There was a significant difference in postoperative extubation time, with the High-group having the highest duration of 15.21±2.34 minutes compared to the Median-group (13.17±1.71 minutes, p<0.001), Low- group (12.72±1.31 minutes, p<0.001), and the Propofol group (12.24±1.23 minutes, p<0.001). No significant difference was found between the Low-group and the Propofol group, while the Median-group still showed higher postoperative extubation time compared to the Propofol group (p=0.008). Conclusion Compared to propofol, total intravenous induction and maintenance with high and median dosages of remimazolam may prolong postoperative extubation time. Remimazolam can be safely used for induction and maintenance at various doses while not increasing the likelihood of adverse events.
Decadal-scale variability and global warming affect spring timing and forest growth across the western Great Lakes region

The Great Lakes region of central North America has warmed by 1–2 degrees Celsius on average since pre-industrial times, with the bulk of warming occurring in winter and spring. Within the continental interior, the multi-decadal warming trend is modulated by long-range teleconnections to centers of ocean-atmosphere variability in the North Paci�c and high Arctic, which affect atmospheric dynamics across the mid-latitude. Variability in spring temperatures affects regional ecosystems by altering growing season length and growth phenology, and different ecotypes and species may exhibit unique or diverging responses to climatic changes. Determining the relative in�uence of natural ocean-atmosphere variability versus the ‘secular’ warming trend on spring temperatures is necessary to estimate the range of potential ecological responses to future warming scenarios. This study examines shifts in Great Lakes climate by evaluating the role of warming and major ocean atmosphere climate patterns on interannual variability and multi-decadal trends in spring climatology in long observational records and leading modes of ocean-atmosphere circulation over the Arctic and North Paci�c. From the analysis of climatology, this study also measures the sensitivity of regional forests to variation and trend in temperature using long-term growth records from tree-rings and satellite data. Using a modeling approach designed to test for regime shifts in time series data, this research shows that mid-continent spring climatology is strongly in�uenced by winter phases-changes in the North Paci�c, and that regional forests show a strengthening response to the trend in spring climate during the last half-century.
DEEP LEARNING FOR DOCUMENT CLUSTERING: A SURVEY, TAXONOMY AND RESEARCH TREND

Information is stored in several forms such as pictures, web pages, sound and video, but 80% is stored as a text. Quick searching for a specific text document depends totally on the accuracy of the classification of the document's subject with a similar group of documents. This process is called documents clustering. Recently, deep learning techniques have achieved distinguish results in solving the problems facing documents clustering such as complex semantics and high dimensionality. This paper aims to examines a comprehensive review related to documents clustering, and survey the recent work in document clustering using deep learning methods . The proposed taxonomy represents knowledge that helps researchers to understand and follow up previous works in this area, and developing or creating new methods and a comparative analysis was made between popular dataset, performance metrics, deep learning frameworks and library used in deep learning clustering documents.
Municipios y gestion forestal en el tropico Boliviano

This book looks at the role of municipal governments in lowland Bolivia in forest management since passage of a popular participation law in 1994 and a new forestry law in 1996. It covers issues related to logging, protected area management, land use planning, indigenous territories, and non-timber forest products. Most of the book consists of nine case studies of specific municipalities or groups of municipalities. The book concludes that decentralisation has opened new opportunities for more equitable access to forest resources and their benefits, but that local people's capacity to take advantage of these opportunities varies. Initial indications point to both positive and negative effects on natural resource management, but it remains too early to determine whether the net impact of decentralisation on forests will be positive or negative.

Contribution to the Synthesis, Characterization, Separation and Quantification of New N-Acyl Thiourea Derivatives with Antimicrobial and Antioxidant Potential

The present study aimed to synthesize, characterize, and validate a separation and quantification method of new N-acyl thiourea derivatives (1a–1o), incorporating thiazole or pyridine nucleus in the same molecule and showing antimicrobial potential previously predicted in silico. The compounds have been physiochemically characterized by their melting points, IR, NMR and MS spectra. Among the tested compounds, 1a, 1g, 1h, and 1o were the most active against planktonic Staphylococcus aureus and Pseudomonas aeruginosa, as revealed by the minimal inhibitory concentration values, while 1e exhibited the best anti-biofilm activity against Escherichia coli (showing the lowest value of minimal inhibitory concentration of biofilm development). The total antioxidant activity (TAC) assessed by the DPPH method, evidenced the highest values for the compound 1i, followed by 1a. A routine quality control method for the separation of highly related compounds bearing a chlorine atom on the molecular backbone (1g, 1h, 1i, 1j, 1m, 1n) has been developed and validated by reversed-phase high-performance liquid chromatography (RP—HPLC), the results being satisfactory for all validation parameters recommended by the ICH guidelines (i.e., system suitability, specificity, the limits of detection and quantification, linearity, precision, accuracy and robustness) and recommending it for routine separation of these highly similar compounds.
Prevalence of Hypocortisolemia in Patients with Sepsis or Septic Shock (The HIS Study) Presenting to the Emergency Department

Abstract Background: Cortisol response to stressors (hypothalamic–pituitary–adrenal axis, autonomic nervous system, and immune system) plays a vital role in maintaining stable metabolic homeostasis. This study was done to assess the prevalence of hypocortisolemia in patients presenting to ED with sepsis and/or septic shock. Methods: This prospective observational study was done from July 2020 to April 2021. Serum cortisol levels were measured in patients with sepsis and septic shock, and their clinical and laboratory profile was categorized, coded, and analyzed. Results: Ninety-eight patients were included, of which serum Cortisol <10 μg/dl was noted in 7 (7.2%) patients. The cohort’s mean age was 52.9 (SD: 15.3) years with a male predominance (n-61; 62.2%). Most common presenting complaint was fever (n-52; 53.1%), followed by abdominal pain (n-24; 24.5%), and breathing difficulty (n-14; 14.3%). Systolic blood pressure <90 mmHg and tachycardia were seen in 63 patients (64.3%). Assessment of diet and native medication use did not demonstrate a predisposition to hypocortisolemia. The median (IQR) arterial lactate values were lower in the hypocortisolemic group: 2.2 (1.2–2.5) as compared to the non-hypocortisolemic group: 3.7 (2.2–8.0). Patients with septic shock without hypocortisolemia were noted to have a higher mean lactate level (2.6 ± 1.3 Vs 5.4 ± 3.9) and lower platelet counts compared to those with low cortisol levels. Patients with normal cortisol levels (n-38; 38.8%) still had low ACTH values. Conclusion: The prevalence of hypocortisolemia was lower when compared to other Indian studies. Diet and native medication use do not predispose Indians to hypocortisolemia.
Quantitative aspects of relative growth and sexual dimorphism in Protoceratops

The Upper Cretaceous Djadochta Formation of Mongolia has yielded a remarkable ontogenetic series of skulls and skeletons of the primitive ceratopsian dinosaur, Protoceratops andrewsi. Twenty-four skulls in the collection of the American Museum of Natural History are subjected to formal biometric analysis for the first time. Allometric coefficients are calculated for 40 variables. Characters of the frill are found to be very variable, and ontogenetic changes in the arrangement of the adductor muscles presumed to originate from it cannot be interpreted as improving or even maintaining the functional constancy of the masticatory system. A definitive determination of sexual dimorphism was permitted by principal coordinates analysis, and measurements of the frill play a prominent part in the dimorphism, verifying that in its development the frill has considerably more significance than simply serving as a site of origin of masticatory muscles. The sample consists of 8 juveniles, 8 males and 7 females, with one individual indeterminate; males and females apparently attained about the same size.
