The Effect of Union Activities on Employee’s Performance: A Case Study at the Bawku Presbytarian Hospital

The Labour Act 2003, Act 651 serves as guide to help foster a harmonious relationship between management and employees. It is paramount to acknowledge the significant role that Union activities have played. Amongst them are; bargaining on behalf of employees, bringing industrial harmony among employees and employers, serving as a guide and direction for employees to direct their grievances and many more. The study was to find out the impact of union activities on the performance of employees. The specific objectives of the study were: To identify the main strategies used by trade unions to protect the interest of members, To find out the benefits associated with joining trade unions and, To find out the effects of trade unions on workers performance. The significance of the study was to find out the socioeconomic good of workers at the Bawku Presbyterian Hospital and help unveil the problems associated with trade unions and its impact on their performance. The researchers through questionnaires used 70 respondents from the Bawku Presbyterian hospital who are members of Health Service Workers Union. Out of the findings 64% of the health workers said trade unions help workers to get their demands. The methodology used for the study was descriptive in nature. The findings of this study corroborate that of other researches that union activities have effect on workers performance at the workplace. Union activities have impact on the performance on work. This implies that it sounds appropriate for employers to put in place enough structure. Through that, industrial action will be reduced. Base on concrete satisfactory measures, it will be very difficult for workers to embark on strike action.
Tension-Based Optical Coherence Elastography: Mapping the Micro-Scale Strain Tensor Resulting From Tensile Loading

Many load-bearing tissues, e.g., tendon, ligament, and muscle, are primarily subjected to tensile loading. Characterizing the micro-scale mechanical properties of these tissues under tensile loading can help to improve our understanding of the link between tissue mechanics and tissue function. Optical coherence elastography (OCE) maps the three-dimensional (3-D) micro-scale mechanical properties of tissue and has shown promise in many applications. However, demonstrations of tensile loading in OCE, i.e., tension-based OCE, are limited and are typically not sensitive to mechanical heterogeneity in the submillimeter range. In this paper, we present a tension-based OCE technique to image the micro-scale strain tensor in tissue under tensile loading. We use a complex cross-correlation method to measure 3-D displacement and propose segmentation-aided multi-directional weighted least squares method to map the strain tensor in samples that contain non-solid regions. We validate our technique using finite element analysis and demonstrate close correspondence with experimental results using a phantom containing a circular cut-out. We demonstrate tension-based OCE on ex vivo bovine tendon tissue, co-registered with histology, revealing that the microstructural heterogeneity of tissue can result in large local strain in tensor components other than that along the direction of the applied load.
Impact of the industrial activity on groundwater quality (case of study: El-Kalitoussa Region Northeast Algeria)

: The contamination of groundwater by toxic compounds even in low concentrations can compromise the exploitation of the resource for long periods. This work is in this theme. Indeed, the objective of this study is the determination of the impact of some heavy metals on the quality of water resources generated by the discharges of some industrial units in the region of El-Kalitoussa. The results obtained have identified the real threat of industrial pollution on the receiving environment (wells, boreholes and lake). However, the state of contamination of groundwater by heavy metals has been achieved by processing analytical results according to a methodology mono and bidimensional using computer tools. This metallic pollution is highlighted by an abnormally high average content in the majority of the analyzed water points for iron, lead and nickel. While copper has an average concentration at the tolerance limit. However, the highest concentrations of heavy metals measured show that the closer the wells and boreholes are to industrial waste, the more vulnerable they become to possible contamination.
Inequalities for mixed projection bodies

Mixed projection bodies are related to ordinary projection bodies (zonoids) in the same way that mixed volumes are related to ordinary volume. Analogs of the classical inequalities from the Brunn-Minkowski Theory (such as the Minkowski, Brunn-Minkowski, and Aleksandrov-Fenchel inequalities) are developed for projection and mixed projection bodies
Hospital Practices for Respiratory Isolation for Patients With Suspected Tuberculosis and Potential Application of Prediction Models

Hospitalized persons with suspected pulmonary tuberculosis (PTB) are placed in airborne isolation to prevent nosocomial infection, as recommended by the Centers for Disease Control and Prevention (CDC). There is significant evidence that clinicians overuse this resource due to an abundance of caution when confronted with a patient with possible PTB. Many researchers have developed predictive tools based on clinical and radiographic data to assist clinicians in deciding which patients to place in respiratory isolation. We assessed the isolation practices for an urban hospital serving a large immigrant population and then retrospectively applied seven previously derived prediction models of isolation of PTB to our population. Our current clinical practice results in 76% of patients with PTB being placed in isolation on admission. However, 208 patients without PTB were placed in isolation unnecessarily for a total of 584 days. Four models had sensitivities greater than 90%, and two models had sensitivities of 100%. The use of these models would have potentially saved more than 150 days of patient isolation per year.
Mental health of recently arrived male refugees in Germany reporting sexual violence

ABSTRACT Conflict-related sexual violence (CRSV) is one of the most severe and stigmatizing human rights violations. The recognition of men and boys as targets of sexual violence is a rather recent development. In the present study data on experiences of sexual violence as well as mental health outcomes were analysed in recently arrived male refugees (N = 392) in Germany. Almost one third of the men interviewed (n = 128; 32.7%) reported having experienced sexual violence. Compared to male refugees without experiences of sexual violence, male refugee survivors showed higher prevalence rates of PTSD. Moreover, some differences were found between the subgroups on the single symptoms level, indicating higher severity in those affected by sexual violence, including negative alterations in cognition/mood, suicidal ideation, and nervousness or shakiness inside. The findings provide initial data on prevalence of sexual violence and related mental health outcomes in male refugees newly arrived in Germany and emphasize the significance of sexual violence as a risk factor for different mental health outcomes. This provides clear implications for health care professionals that could aid them in better identifying those affected. Finally, further research is urgently needed that takes a closer, more differentiated look at sexual violence in male refugee populations.
Fine-Scale Structures of the Evershed Effect Observed by the Solar Optical Telescope aboard Hinode

The small-scale structure of the Evershed effect is being studied using data obtained by the Spectropolarimeter and the Broadband Filter Imager of the Solar Optical Telescope aboard Hinode. We find that the Evershed flow starts at the leading edge of inwardly migrating bright penumbral grains, and turns to nearly a horizontal flow preferentially in the dark lanes of the penumbra. A number of small elongated regions that have an upward motion of 1 km s 1 are found in the deep photosphere distributed over the penumbra. They are cospatial with bright grains and have relatively horizontal magnetic fields. A number of patches having a strong downward motion associated with the opposite magnetic polarity from the sunspot are also found in the mid and outer penumbra. They could be identified as foot points of the Evershed flow channels, though the identification of individual pairs is not straightforward. Our results provide strong support for some recent findings from ground-based high-resolution observations, and are in general agreement with the well-known picture of the uncombed structure of the penumbra, in which the penumbrae consist of rising flux tubes carrying nearly horizontal Evershed flows embedded in more vertical background magnetic fields.
The Effect of Principal Transformational Leadership, Work Ethics and Achievement Motivation on the Performance of Junior High School Teachers in Balangan Regency

This study attempts to describe and analyze the direct and indirect effects of Achievement Motivation as an intermediary variable in the correlation between the Principal's Transformational Leadership, Work Ethic, and teacher performance. The population of 203 junior high school teachers in Balangan Regency is sampled using proportionate random sampling to get a sample of 176 individuals. This research analysis employed descriptive and inferential SPSS 22 statistics. Using a questionnaire, information was gathered about Transformational Leadership of Principals (48 items), Work Ethics (35 items), Motivation for Achievement (30 items), and Teacher Performance (26 things). (1) The principal's transformational leadership, the teacher's work ethic, the teacher's success motivation, and the teacher's performance all fall into the "high" category, as indicated by the study's findings. The principal transformational leadership has a direct impact on teacher work ethic, teacher achievement motivation, and teacher performance. (3) There is an indirect effect of the principal's transformational leadership, teacher work ethic, and teacher achievement motivation on teacher performance.
Worst-Case Analysis of Digital Control Loops with Uncertain Input/Output Timing

Benchmark Proposal: The implementation of digital control systems in complex multicore or distributed real-time systems results in non-deterministic input/output timing. Such timing deviations typically lead to degraded performance or even instability, which in turn may jeopardize safety goals. We present the problem of proving worst-case guarantees for given input/output timing bounds as a benchmark for the verification of hybrid dynamical systems.
Role of S100A8/A9 in Platelet–Neutrophil Complex Formation during Acute Inflammation

Acute respiratory distress syndrome (ARDS) due to pulmonary infections is associated with high morbidity and mortality. Upon inflammation, the alarmin S100A8/A9 is released and stimulates neutrophil recruitment mainly via binding to Toll-like receptor 4 (TLR4). TLR4 is also expressed on platelets, which modulate the immune response through direct interaction with leukocytes. In a murine model of Klebsiella pneumoniae-induced pulmonary inflammation, global S100A9 deficiency resulted in diminished neutrophil recruitment into the lung alveoli and neutrophil accumulation in the intravascular space, indicating an impaired neutrophil migration. A lack of TLR4 on platelets resulted in reduced neutrophil counts in the whole lung, emphasising the impact of TLR4-mediated platelet activity on neutrophil behaviour. Flow cytometry-based analysis indicated elevated numbers of platelet–neutrophil complexes in the blood of S100A9−/− mice. Intravital microscopy of the murine cremaster muscle confirmed these findings and further indicated a significant increase in neutrophil–platelet complex formation in S100A9−/− mice, which was reversed by administration of the S100A8/A9 tetramer. An in vitro bilayer assay simulated the murine alveolar capillary barrier during inflammation and validated significant differences in transmigration behaviour between wild-type and S100A9−/− neutrophils. This study demonstrates the role of S100A8/A9 during platelet–neutrophil interactions and neutrophil recruitment during pulmonary inflammation.
The turbulent interstellar medium and pressure-bounded molecular clouds

The existence of turbulence throughout the interstellar medium suggests that an appropriate value for the average pressure may be P/K larger than about 10,000. Negative-index polytropic models of interstellar clouds in equilibrium with an external medium at these pressures are predicted to have sizes, line widths, masses, and size-line width and size-density relations in good agreement with those observed and inferred for dark clouds. Thus these observed features of interstellar clouds do not require that they be completely self-gravitating or 'virialized' in the commonly used sense. 41 references.
Age-Associated Changes in Proximal Femur Morphology Affect Femoral Component Sizing in Cementless Hip Arthroplasty

Background In cementless hip arthroplasty, the femoral component should obtain firm fixation within the endosteal bone and achieve adequate reconstruction of hip joint biomechanics simultaneously. Previous anatomical studies described age-related changes of the proximal femoral canal, such as canal widening, which theoretically necessitates the use of larger stem sizes in elderly patients. This study examines a potential association between patients’ age at surgery and the implant size of a cementless femoral component. Material and methods A total of 13,423 primary hip arthroplasties with a single cementless stem registered in the Dutch Arthroplasty Register (LROI) were included. Patient characteristics (ie patients’ age, sex, height and weight at time of surgery) and femoral component size were derived. A one-way ANCOVA was used to compare the mean stem size between age groups, and multivariable linear regression analysis was used in order to investigate to which extent ageing impacted stem size. Results Each subsequent age- group (ten-year intervals) had a significantly larger mean stem size than the prior age- group. Multivariable linear regression analysis revealed that age is positively correlated with stem size and that this correlation is more prominent in females than in males (beta = .046, P < .001 and beta = .028, P < .001 respectively). Interpretation Implant size is positively correlated with age, in particular in females and independently from investigated anthropometric characteristics. The present study endorses that the femoral canal morphology is related to patients’ characteristics such as age and sex. The morphology will subsequently influence implant sizing and therefore may have biomechanical and clinical implications.
Cognitive and behavioral processes predict anxiety and depression in patients with pulmonary hypertension

Abstract Emotional and psychological difficulties cannot fully be explained by disease‐related factors in people with pulmonary hypertension (PH). This study examined the relationship between anxiety, depression, demographic, objective and subjective PH factors, and self‐reported cognitive and behavioral processes, which have been associated with mood in clinical and nonclinical samples. This is a secondary analysis of baseline data from 77 adults with PH who took part in a randomized controlled trial of a self‐help intervention targeting anxiety in PH. Participants completed self‐report measures including: demographic (age, gender, ethnicity, education, employment) and clinical questionnaire (PH diagnosis, functional class, years since diagnosis), depression (PHQ‐9), anxiety (GAD‐7), health‐related quality of life (emPHAsis‐10), dyspnea (D12), and cognitive and behavioral processes (CBP‐Q) scale. Data were analyzed using correlational and regression analyses. Overall, 70% and 63% of participants scored above the clinical cut off for anxiety and depression, respectively. Demographics were not associated with anxiety or depression. PH‐related factors were correlated with depression but not anxiety. A multiple regression analysis suggested dyspnea and cognitive processes significantly predicted anxiety whereas behavioral processes were not a unique predictor. In contrast, dyspnea and behavioral processes predicted depression whereas cognitive processes did not. While a body of evidence exists demonstrating people with PH are more likely to experience anxiety and depression, less is known about factors that cause and maintain these disorders. Findings highlight the significance of subjective factors that could be a target for screening and psychological treatments for emotional difficulties, such as cognitive behavioral therapy.
Changes and Associations Between Gait Biomechanics and Knee Inflammation After Aspiration and Glucocorticoid Injection for Knee Osteoarthritis

Although knee inflammation is thought to adversely affect joint function in patients with knee osteoarthritis (OA), the effects of reducing knee inflammation on gait biomechanics and strength are unknown. Our objectives were to compare ultrasound (US) measures of knee inflammation, gait biomechanics, knee extension and flexion strength, and pain before and after knee aspiration and glucocorticoid injection, and to explore associations among changes.
The Association between the North Atlantic Oscillation and the Southern Oscillation in the Northern Hemisphere

Abstract The North Atlantic Oscillation (NAO) and Southern Oscillation (SO) are compared from the standpoint of their association with Northern Hemisphere winter mean distributions of sea-level pressure (SLP) and 500 mb height. The NAO and SO are associated with significant SLP differences over much of the hemisphere except for Siberia and western North America. Significant SLP and 500 mb height differences occur in the NAO over the Atlantic Ocean and near Baja California, while in the SO they occur over the Pacific Ocean, India and the western Atlantic. Only over the latter region do large pressure and height variations consistently occur in the extremes of both oscillations; these are also associated with winter temperature variability over the southeastern United States. For example, during winter 1982–83, when the two oscillations simultaneously reached extremes, the NAO was associated with record December warmth east of the Mississippi River, but during January and February the SO dominated the heigh.
Impact of mutations on pregnancy outcome in patients with myeloproliferative neoplasms

The impact of driver and other somatic mutations on pregnancy outcomes is unknown. The purpose of this study was to report the management and outcome of pregnancies in a cohort of myeloproliferative neoplasms (MPN) patients, particularly to evaluate the impact of somatic mutations. The cohort included consecutive patients with MPN who had a least one confirmed pregnancy. The primary outcome was live births. Secondary outcomes were thrombotic and major bleeding events. Between 2010 and 2021, 29 pregnancies occurred in 24 individuals with MPN. Aspirin was used in 24 cases (83%) and interferon alfa in five (17%). There were 24 live births (83%). There were three thrombotic events, two antepartum and one postpartum. Miscarriages and thrombotic events occurred in JAK2‐mutated and triple negative, but not CALR‐mutated, MPN. Additional somatic mutations were rare, and there were no apparent associations with pregnancy loss or complications. While JAK2 V617F is associated with an increased risk of thrombosis, its impact on pregnancy outcome has been inconsistently reported. The association between triple negative MPN and adverse pregnancy outcome has not previously been reported. While limited by small numbers, this study underscores the importance of describing driver and other mutations to direct optimal antenatal care in individuals with MPN.
Immunohistochemical Markers of the Epithelial-to-Mesenchymal Transition (EMT) Are Related to Extensive Lymph Nodal Spread, Peritoneal Dissemination, and Poor Prognosis in the Microsatellite-Stable Diffuse Histotype of Gastric Cancer

Simple Summary The epithelial-to-mesenchymal transition (EMT) is a biological process in which epithelial cells transform into mesenchymal-like cells that are capable of invasion, migration, and metastasis. EMT-positive diffuse gastric cancer shows a strong association with extensive lymph nodal metastases, advanced pTNM stage, peritoneal dissemination, chemo-resistance, and poor prognosis. E-cadherin, CD44, and ZEB-1 are cheap immunohistochemical markers of the EMT phenotype. Within the Lauren diffuse histotype, EMT status identifies two different phenotypes (EMT− and EMT+) with distinct clinico-pathological and prognostic characteristics. Abstract Background: Although the prognostic value of the epithelial-to-mesenchymal transition (EMT) in gastric cancer has been reported in several studies, the strong association with the diffuse type may represent a confounding factor. Our aim is to investigate potential correlations among EMT status, tumor advancement, and prognosis in diffuse gastric cancer. Methods: Between 1997 and 2012, 84 patients with microsatellite-stable (MSS) diffuse-type tumors underwent surgery. The EMT phenotype was assessed with the E-cadherin, CD44, and zinc finger E-box binding homeobox 1 (ZEB-1) immunohistochemical markers. Results: Forty-five out of 84 cases (54%) were EMT-positive; more advanced nodal status (p = 0.010), pTNM stage (p = 0.032), and vascular invasion (p = 0.037) were observed in this group. The median numbers of positive nodes (13 vs. 5) and involved nodal stations (4 vs. 2) were higher in the EMT-positive group. The cancer-related survival time was 26 months in EMT-positive cases vs. 51 in negative cases, with five-year survival rates of 17% vs. 51%, respectively (p = 0.001). The EMT status had an impact on the prognosis of patients with <70 years, R0 resections, or treatment with adjuvant chemotherapy. Tumor relapses after surgery and peritoneal spread were significantly higher in the EMT-positive tumors. Conclusions: EMT status, when assessed through immunohistochemistry, identified an aggressive phenotype of MSS diffuse-type tumors with extensive lymph nodal spread, peritoneal dissemination, and worse long-term outcomes.
Gathering Giizhik in a changing landscape

Giizhik (gee-zhick; Northern white cedar; Thuja occidentalis ) maintains essential roles in Anishinaabe teachings, ceremony, and lifeways. Anishinaabeg at Bahweting and Gnoozhekaaning have adaptively gathered Giizhik through millennia of change. Over the last century, Giizhik have declined in abundance across their range and future declines are projected due to climate-driven change. Anishinaabe gatherers maintain relationships with Giizhik forests across a gradient of Giizhik dominance; with these relationships and knowledges, gatherers offer important alternatives in forest management planning and practice. The Sault Ste. Marie Tribe of Chippewa Indians at Bahweting, Bay Mills Indian Community at Gnoozhekaaning, and Giizhik gatherers from each community are pursuing forest relations based on Anishinaabe lifeways and relationalities. We describe gathering practices and changes through time based on group discussions and semi-structured interviews with 25 Anishinaabe gatherers and tribal natural resource staff. Spiritual and physical relationships among Anishinaabeg and Giizhik were discussed within the contexts of our original instructions (guidance defining respectful kin relations in this moral universe, handed down through the generations since time immemorial), settler colonialism, and forest management. This work builds upon the concepts of relationalities and collective continuance in the context of Anishinaabe forest relationships. We offer suggestions on ways of respecting and protecting forest communities by putting forest management into the context of forest relationalities.
