Authors: Sibomana Jean Pierre , Ndayambaje Irénée
Published: July 2024

The professional development and performance of teachers in Kicukiro District are very important to ensuring quality education. Despite the responsibilities outlined in the Teachers' Act, including attendance at classes, lesson planning, and student assessment, the report found that there are gaps, particularly in relation to absenteeism and planning. These problems are a threat to student achievement and school performance and show a great need for research and strategies to improve teacher performance. The aim of this study is to examine previous implementations of professional development programs, assess their impact on teaching skills, teaching methods, and subject knowledge, and identify potential barriers to their effective implementation. Through a descriptive correlational research design, primary data were collected through questionnaires, and secondary data were collected through document analysis by selecting 15 principals and 435 teachers. Data analysis included descriptive statistics, correlation, and analysis using SPSS version 22.0. The correlation analysis of the variables showed a significant relationship between the different factors. For example, there is a significant positive relationship between teacher training and effective teaching practices (r = 0.611, p < 0.01), students’ performance (r = 0.940, p < 0.01), and teacher professional growth (r = 0.890, p < 0.01). Likewise, undergraduate and short courses are positively correlated with effective teaching (r = 0.598, p < 0.01), student performance (r = 0.552, p < 0.01), and teacher professional growth (r = 0.550, p < 0.01). Continuing professional development (CPD) has a significant positive relationship with effective teaching practices (r = 0.732, p < 0.01), student engagement (r = 0.431, p < 0.01), and teacher professional growth (r = 0.469, p < 0.01). In addition, seminars were positively correlated with effective teaching methods (r = 0.255, p < 0.01), student performance (r = 0.496, p < 0.01), and teacher professional growth (r = 0.521, p < 0.01). These results indicate that these training and development activities are associated with improved teaching practices, student outcomes, and teacher professional growth. Finally, the research highlighted the importance of CPD for teachers and their job satisfaction. The research recommended that the government should invest in supporting teachers and schools in providing the training and resources that are needed for teacher development, hence the performance.
Modelling Herbivory Impacts on Vegetation Structure and Productivity

Published: July 2024

Abstract. Animal herbivory can have large and diverse impacts on vegetation and hence on the state and function of ecosystems. Despite this, quantitative understanding of vegetation responses to consumption of green leaf tissue by herbivores is currently lacking and presents a critical gap. More and more species are becoming endangered or extinct, whereas ecosystem restoration and rewilding are also increasingly moving into the focus of the scientific community. The large-scale impacts of changes in herbivore abundance on ecosystem function have yet to be investigated. Process-based modelling can help to quantify how animals affect important processes, such as ecosystem carbon cycling. To do so, we linked the dynamic global vegetation model LPJ-GUESS with the Madingley model, a model of multi-trophic functional diversity. This implementation allows us to simulate feedbacks between the availability of green vegetation biomass, herbivory and the whole trophic chain and vice versa. In the coupled model system, we see an overall reduction in ecosystem productivity, leaf area index and carbon mass, compared to the stand-alone version of LPJ-GUESS. The impact of herbivory is most prominently visible in the boreal ecosystems. We evaluated LPJ-GUESS output against remote sensing datasets and flux measurements and find that the coupled LPJ-GUESS/Madingley model preserves LPJ-GUESS’s ability to predict realistic biome distributions and carbon pools.
Advances in conceptual modelling of the variable nature of Dansgaard-Oeschger events

Published: July 2024

Abstract. This study introduces a novel dynamical systems model designed to capture the highly non-periodic nature of Dansgaard-Oeschger (DO) events. Such events are difficult to model adequately due to their variable durations — some lasting around a century, while others span multiple millennia — and the occurrence of short precursor events that precede the longer DO events despite similar boundary climate conditions. Utilizing a simplified two-equation framework derived from the Stommel model, our approach integrates an internal control parameter which acts as a feedback parameter on the Antarctic Bottom Water (AABW) formation. Through both analytical and numerical methods, we establish a suitable parameter domain within which the newly adjusted models can accurately replicate the paleoclimatic records of DO events as described by summary statistics derived from ice-core data. The analysis also shows that without the novel control parameter, the model does not have a suitable parameter domain in which it can reproduce the wide range of event characteristics seen in the ice-core record. The study provides new insights into the underlying mechanisms driving these highly significant climate phenomena and the necessary timescale in which they are forced, by allowing the new model's parameters to vary through time. This allows our model to achieve unprecedented precision in capturing a realistic sequence of DO events with timing characteristics matching those of the observational record. This refined model not only enhances our understanding of the DO cycles but also demonstrates the potential of simple dynamical systems to simulate complex climate interactions.
Control of spatio-temporal variability of ocean nutrients in the East Australian Current
Authors: Jeffers Megan , Chapman Chris , Sloyan Bernadette M. , Bostock Helen
Published: July 2024

Abstract. The East Australian Current (EAC), the South Pacific's southward flowing western boundary current, dominates the marine environment of the east coast of Australia. Upwelling of deep EAC nutrient rich water into the oligotrophic surface waters is very important for maintaining upper ocean productivity. However, the role of EAC dynamics in upper ocean nutrient variability and resulting productivity is poorly understood. In this study we use physical and biogeochemical data collected from 2012–2022 to improve understanding of the variability of the nutrients in the upper water column at ~27° S, a subtropical region strongly influenced by EAC. The 10-year data set shows that there is a seasonal increase in nutrient concentrations in the upper water column (0–200 m) in the Austral spring (September–November) and autumn (March–May), and a minimum in winter (June–August). We also find that the nutrient concentrations in the upper water column are influenced by the position of the EAC jet. Two main modes of variability in the EAC’s position are identified: an inshore mode with jet flowing along the continental slope and; an offshore mode with the current core detached from the continental slope and flowing over the adjacent abyssal plain. The position of the EAC jet influences the location of upwelling of nutrient-rich water at depth (>200 m). For the EAC inshore mode, cooler, nutrient-rich waters are restricted to the area of the continental shelf and slope that is inshore of the EAC. The offshore mode exhibits a wider distribution of nutrient-rich waters over both the inshore shelf and slope and, offshore abyssal Tasman Sea. Our analysis highlights the important interactions between nutrient concentrations and distribution and the highly variable EAC, which has implications for primary production, fisheries, and the biological carbon pump.

Abstract. Based on the ongoing large climatic and environmental changes and the history of science coordination in Svalbard leading to the development of Svalbard Integrated Arctic Earth Observing System (SIOS), we present an overview of the current gaps in knowledge and infrastructure based on a synthesis of the recommendations presented in the annual State of Environmental Science in Svalbard (SESS) reporting of SIOS. Recommendations from the first 4 years of SESS reporting represent the point of view of the wide scientific community operating the large observing system implemented in Svalbard (SIOS) since 2018 and aim to identify the scientific potential to further develop the observing system. The recommendations are bottom-up inputs for a continuous process that aims to accomplish the vision and mission of SIOS: optimizing, integrating and further developing the observing system in an Earth system science (ESS) perspective. The primary outcome of the synthesis work is the evidence that ESS in SIOS has, during the first 4 years of operation, naturally developed from individual scientists or smaller groups of scientists to larger disciplinary international groups of scientists working together within the different environments (the atmosphere, the cryosphere, and marine and terrestrial environments). It is clear that strategic efforts towards interdisciplinarity are necessary for operating fully at ESS scale in Svalbard. As Svalbard is experiencing the largest ongoing warming in the Arctic and worldwide, SIOS is in a unique position to perform a full-scale study of all processes impacting ESS dynamics and controlling the water cycle using all parts of the SIOS observation network, with a large potential for increasing the understanding of key mechanisms in the Earth system. We also identify the potential to upscale Svalbard-based observations collected in SIOS to pan-Arctic and global scales, contributing to full-scale ESS.

Abstract. Comprehensive large sample hydrological datasets, particularly the CAMELS datasets (Catchment Attributes and Meteorology for Large-sample Studies), have advanced hydrological research and education in recent years. These datasets integrate extensive hydrometeorological observations with landscape features, such as geology and land use, across numerous catchments within a national framework. They provide harmonised large sample data for various purposes, such as assessing the impacts of climate change or testing hydrological models on a large number of catchments. Furthermore, these datasets are essential for the rapid progress of data-driven models in hydrology in recent years. Despite Germany's extensive hydrometeorological measurement infrastructure, it has lacked a consistent, nationwide hydrological dataset, largely due to its decentralised management across different federal states. This fragmentation has hindered cross-state studies and made the preparation of hydrological data labour-intensive. The introduction of CAMELS-DE represents a step forward in bridging this gap. CAMELS-DE includes 1555 streamflow gauges with hydro-meteorological time series data covering up to 70 years (median length of 46 years and a minimum length of 10 years), from January 1951 to December 2020. It includes consistent catchment boundaries with areas ranging from 5 to 15,000 km2 along with detailed catchment attributes covering soil, land cover, hydrogeologic properties and data about human influences. Furthermore, it includes a regionally trained Long-Short Term Memory (LSTM) network and a locally trained conceptual model that were used as quality control and that can be used to fill gaps in discharge data or act as baseline models for the development and testing of new hydrological models. Given the large number of catchments, including numerous relatively small ones (617 catchments < 100 km2), and the time series length of up to 70 years (156 catchments), CAMELS-DE is one of the most comprehensive national CAMELS datasets available and offers new opportunities for research, particularly in studying long-term trends, runoff formation in small catchments and in analysing catchments with strong human influences.
Shallow-landslide stability evaluation in loess areas according to the Revised Infinite Slope Model: a case study of the 7.25 Tianshui sliding-flow landslide events of 2013 in the southwest of the Loess Plateau, China

Abstract. The occurrence of shallow loess landslides induced by prolonged heavy rainfall is prevalent in loess-dominated regions, often leading to property damage, human casualties, and sediment pollution. Developing an accurate prediction model for shallow landslides in loess areas is crucial for effective landslide mitigation. In 2013, prolonged heavy rains from 19–25 July triggered mass sliding-flow loess landslides in Tianshui, China. Landslide data, along with the characteristics of the sliding-flow loess landslides, were obtained through extensive field investigations and remote sensing interpretations. The sliding-flow loess landslide event demonstrated clustering, high density, small areas, and long travel distance. The depth of the sliding surface is correlated with the saturated layer resulting from rainfall infiltration; it is typically less than 2 m deep and negatively correlated with slope steepness. Based on the common characteristics of shallow loess landslides, the mechanisms involved in the sliding-flow landslide are proposed. The Revised Infinite Slope Model (RISM) was introduced using an equal differential unit method to address deficiencies when the safety factor remains constant or increases with increasing slope greater than 40°, as calculated using the Taylor slope infinite model. The relationship between the critical depth and the slope of the shallow loess landslide was determined. The intensity–duration (I–D) prediction curve of the rainfall-induced shallow loess landslides for different slopes was constructed and combined with the characteristics of rainfall infiltration for use in forecasting regional shallow loess landslides. Additionally, the influence of loess strength on the shallow loess landslide stability was analyzed. The shallow loess landslide stability responds to slope and cohesion but is not sensitive to the internal friction angle.

Published: July 2024

This study aims to investigate the effect of flood on polio vaccination coverage among children aged 0-2 years in Pakistan, with a particular emphasis on the impact of floods on vaccination rates in both urban and rural areas, male and female, families of varying sizes, families with educated and uneducated heads, and the socio-economic status of households. The study utilized household-level data from the Pakistan Social and Living Standards Measurement surveys conducted between 2004-05 and 2014-15. Difference-in-Differences (DID) analysis and inverse probability of treatment weighting (IPTW) were employed, treating the flood as a quasi-natural experiment. The flood in 2010 in Pakistan disrupted polio vaccination coverage significantly; particularly in rural areas and among households led by uneducated parents. During the flood, 135 out of 1000 children aged 0-2 years were not fully vaccinated against poliovirus, and this number varied across different regions and family sizes with 171 fewer children per 1000 fully vaccinated during the flood in rural flooded areas. The adverse effects persisted for several years, with disparities observed based on parental education, gender, and household assets. Despite some recovery, the decline in polio immunization coverage remained significant in the years following the flood, especially in large families and impoverished households. Disparities based on gender, socioeconomic status, parental education, and family size were evident. Regardless of global efforts to combat polio, natural disasters like floods pose significant challenges to immunization programs, emphasizing the need for targeted interventions and improved disaster preparedness in vulnerable regions.

Renewable energies stand out as fundamental solutions to address climate change, providing environmental benefits and promoting energy independence. However, renewable plants face challenges such as intermittency, initial costs, and visual effects on the surroundings. The GEDERlab is an innovative energy hub developed at the Universitat Politècnica de València (UPV) that integrates four renewable energies (solar, wind, biogas, and hydraulic) to tackle these challenges. The main objective is only to optimize complementarity among energies but also to develop strategies for efficient storage and optimal management. This project goes beyond research and it aims to become a replicable model at the municipal level. Therefore, the results are extrapolated to a rural municipality in the Valencian Community, to improve energy efficiency, promote circular economy principles and utilize waste as resources. So, in this paper, the components of the energy hub GEDERlab, their integration, and the control system are described to encourage the integration of renewable energy resources.
Thermoelectric generator for energy production from renewable sources
Authors: R. Mecke  , P. Kußmann
Published: July 2024

Thermoelectric generators (TEG) produce electrical energy from a temperature difference between the cold and hot side of TEG modules (Seebeck effect); in principle, they can be used at temperature differences greater than 3 K [1]. Thermoelectric energy generation is primarily known for supplying self-sufficient sensors or in exhaust systems of motor vehicle internal combustion engines [2], where high temperature differences of up to 700 K are used. In this paper, basic investigations are carried out in order to expand the power range of thermoelectric energy generation and their potential for the energy transition. To this end, the area of application should be expanded to include medium and small temperature differences. The output characteristic of a TEG module has a power maximum, which increases quadratically with the temperature difference and linearly with the module area. At a temperature difference of 40 K, an output of 250 W/m2 can be generated. A solar module can generate 150 W/m2 in full sunlight; this output is only available for 12 % of the year given the 1000 full-load hours of sunshine that are usual in our latitudes. A continuous thermoelectric energy source could provide energy all year. Under optimal conditions, an annual usage time of 5000 hours and a service life of 10 years, electricity production costs of around 10 Cents/kWh can be expected [3]. This price is quite comparable to other renewable energy sources (photovoltaics, wind).
Power quality and efficiency functionalities for a three-level Dynamic Voltage Restorer on low voltage grids

Published: July 2024

Back-to-back PWM inverter based bidirectional dynamic voltage restorers (DVR) may have worse efficiency than mechanical or SCR based solutions, but they are able to provide a continuously variable voltage in series with the grid. As the injected waveform does not need to be sinusoidal, additional features may also be implemented in software. In this paper it is shown that the compensation of voltage harmonics, flicker, and even voltage transients are all possible to some extent. The power required for the series voltage injection does not need to originate from the same phase where it is injected. Drawing power from the less problematic phases can also be used to increase the voltage symmetry on the unregulated side of the device. It is shown in the paper, that at partial load the complete deactivation of one phase in the active rectifier stage can not only help with asymmetry, but can also increase the efficiency of the system. A method is proposed for the seamless transfer in the active rectifier stage from 3-phase to 2-phase operation and back. It is also shown in the paper, that phase deactivation and electronic bypass of the injection transformer is possible in the output stage as well. The three level half bridge circuit configuration enables this without additional components.

The Muslim Culinary in Ho Chi Minh City
Authors: Phan Tu Anh
Published: July 2024

Ḥalāl food is a common feature in Muslim lives across the world. In Muslim quarters of Ho Chi Minh City, Vietnam, locally-made food products are self-recognized as ḥalāl by the community. Ḥalāl food self-recognition is a tradition that exists within closed Muslim communities based on a process of production and consumption standardized by Muslims alone. However, the urban culinary scene has changed as the Vietnamese government issued policies for enhancing the tourism industry and exhorting Muslim enterprises to produce their typical local products. Using qualitative research methods in combination with document analysis, this article shows the sophisticated and varied culinary trade techniques of the Muslim market in Ho Chi Minh City and Southern Vietnam. Products that are not ḥalāl or that falsely claim to be ḥalāl have been introduced to the market. As a result, the involvement of the local Muslim community in the manufacturing process of these ḥalāl-standardized goods is analysed and examined to prevent the products from falsely claiming to be ḥalāl as well. Cultural aspects of the local Muslim community in food processing of ḥalāl products are often applied in creating tourist products in Muslim neighbourhoods. This research also argues that the market economy in Vietnam brings profits for the country, yet is also challenging for Muslims to produce and consume ḥalāl food.

Rapid Eye Movement (REM) sleep disorder is a parasomnia in which physical activity is present when a state of atonia should be manifest instead. The activity may vary from verbal behaviors (eg. talking or shouting) to more extreme motor behaviors (eg. moving in bed, fighting, standing, moving about, and falling). Men and older individuals are more likely to present with REM disassociation sleep disorders. REM sleep disorders can be a prodrome of a Parkinsonian disorder or Lewey body pathology [1].

A 55 year hypertensive man presented with shortness of breath, productive cough and loss of weight. To rule out underlying malignancy, he underwent F-18 FDG PET/CT which showed bronchiectatic changes and tree-in bud nodules in bilateral lung fields with no definitive of evidence of metabolically active disease to suggest malignancy. There was no organomegaly and pulmonary to aorta ratio was also normal (0.73). However, diffuse FDG uptake was seen in the right ventricle which is uncommon due to less muscular mass in comparison to the left ventricle. The serum NT- pro BNP was raised to 265 pg/ml (upper limit less than 125 pg/ml) confirming heart failure.

Introduction: Pericarditis is a common cause of chest pain. It has many etiologies, which are classified into infectious and non-infectious causes. The majority of cases follow a benign course. Case summary: A 66-year-old female presented with pleuritic chest pain following a febrile illness. She was diagnosed with acute idiopathic pericarditis, and standard treatment was initiated. In the following weeks she returned to the hospital multiple times due to unresolved symptoms. Pericardiocentesis was done and cultures from the fluid grew Listeria monocytogenes. CT scan uncovered metastatic pancreatic malignancy. Rapid symptom resolution was observed following the initiation of appropriate antibiotic treatment. Discussion: While most cases of pericarditis follow a benign course, the presence of high-risk features warrants a thorough investigation. In cases resistant to standard treatment, less common causes of pericarditis should be sought.

We examine the type and magnitude of negative externalities stemming from “zombie” firms in the Greek economy, focusing on investment, employment and productivity. For this purpose, we use a panel dataset of Greek firms broken down by size and sector of economic activity for the period 2002-2021. A descriptive analysis reveals a high positive correlation in the trends between non-performing business loans and the number of zombie companies in the Greek economy over the last twenty years. Through quantitative analysis, significant direct and indirect effects emerge from the degree of density of zombie firms at the total economy and sectoral levels. First, healthy firms outperform zombie firms in terms of investment growth, employment growth and productivity levels. Second, a high concentration of capital in zombie firms negatively affects the rate of investment growth of healthy firms in specific sectors of economic activity. Third, a high concentration of capital in zombie firms forces healthy firms to increase their overall productivity in order to survive. Fourth, a high concentration of capital in zombie firms prevents the reallocation of capital to more productive investments across firms and sectors of activity. Finally, younger and larger companies generally perform better in terms of investment and employment growth, and productivity levels. Overall, a faster resolution of zombie firms and non-performing corporate loans, both on and off bank balance sheets, allows a more efficient allocation of resources and can boost investment, employment and growth rates in the Greek economy in the medium to long term.

Published: July 2024

Introduction

The pectoralis major (PM) muscle is the largest and most superior muscle of the anterior chest wall. The PM plays an important role in flexion, adduction, and internal rotation of the arm. The pectoralis major’s size, strength, and anatomical location make it an excellent candidate in transfer surgeries due to its ability to restore balancing forces that may be lost in scapular winging and subscapularis tears. Each of these injuries and pathologies involves the PM muscle in some way, and careful consideration of its anatomy and physiology is necessary. This review article aims to provide a comprehensive overview of the anatomy, physiology, and surgical considerations of the pectoralis muscle with a specific focus on the surgical techniques involving the muscle.

Methods

A comprehensive literature search using a combination of the following terms: pectoralis major, rupture, transfer, chronic subscapularis tear, pectoralis surgery, anatomy, scapular winging, and long thoracic nerve anatomy. There were no limitations with regards to article type or publishing date, but article language was limited to only English.

Conclusion

The pectoralis muscle is an important muscle when it comes to function of the upper extremity primarily or through transfer procedure. Injuries and impairments of the pectoralis major or other muscles of the upper extremity can significantly impact an individual’s quality of life, limiting their ability to perform activities of daily living. A thorough understanding of anatomical, functional, and surgical purposes of the pectoralis muscle is crucial for achieving optimal outcomes and avoiding complications.
Zamach na życie Prezydenta Rzeczypospolitej Polskiej
Authors: Kosmaty Piotr
Published: July 2024

The article addresses some issues related to a particular criminal law-based protection of the President of the Republic of Poland. In view thereof analyzed was art. 134 of the Penal Code which criminalizes any behavior aimed at attempting the life of the President of the Republic of Poland. As the Author has it, the keynote of this provision is, first of all, ensuring a particular criminal law-based protection of the Office of the President who plays the crucial role in guaranteeing the law and order as well as national security. One of the chief guarantor of a streamlined and undisturbed operation of the State organism is the President of the Republic of Poland, perceived not as a specific person but as a subject who personifies the Majesty of the Republic of Poland. An attempt on the life of the person who holds the President’s office may mean the inception of both internal and external destabilization of the country. At the same time, the Author of the article does not deny that the provision also strengthens the protection of life and health of that person, acknowledging, however, that this is an auxiliary subject matter of protection. Moreover, the author believes that the legislator ought to supplement the issues under analyzing in order to penalize any and all behaviors with attributes which imply the preparations for the crime – viz. an attempt on the life of the President of the Republic of Poland, as the authors of the penal code of 1932 did.

The protection of nature and the environment, the preservation of the diversity of ecosystems without jeopardizing their integrity, and their sustainable development are important for sustainability. The Acarlar Floodplain is an extraordinary tourism and recreation area in terms of its ecological and landscape features. In the Acarlar Floodplain, which has recently become an important tourist destination, it is important to determine the attractions for daily recreation without neglecting the conservation value. The aim of this study is to identify suitable areas for hiking and birdwatching in the region using the weighted overlay method. The results show that most of the region is restricted areas for targeted activities, especially birdwatching, due to the different conservation status of Acar Longoz. The 1st degree suitable areas for hiking activities cover 226 ha and 4169 ha fall under the 2nd degree suitable category. The 1st degree suitable areas for birdwatching cover 16 ha, while the 2nd degree suitable areas cover 487 ha. The results provide essential inputs and an exemplary scientific methodology for the development of the current ecotourism project and wetland management plans.

With the increasing shift toward sustainable development and heightened societal scrutiny, companies are placing greater emphasis on environmental, social, and governance (ESG) disclosures. This study investigates the association between ESG disclosures and financial performance among companies listed on the Saudi Stock Exchange, focusing on how board characteristics influence this relationship. By analyzing a sample of Saudi-listed firms, the research assesses the impact of ESG disclosures, as well as their individual environmental, social, and governance components, on key financial performance indicators: Return on Assets (ROA), Return on Equity (ROE), and Earnings Per Share (EPS). The findings reveal a positive association between overall ESG disclosures and financial performance metrics. Environmental disclosures are particularly effective in enhancing ROA, social disclosures positively affect ROE, and governance disclosures significantly improve EPS. Additionally, the study highlights how board characteristics—such as ownership, size, and independence—moderate the relationship between ESG disclosures and financial performance. Specifically, board ownership has a positive moderating effect, while the impacts of board size and independence vary depending on the financial metric in question. These results emphasize the importance of ESG disclosures in influencing financial performance and underscore the significant role of board governance in strengthening this relationship. The study provides valuable insights from the Saudi context, offering both theoretical and practical implications for policymakers, investors, and corporate managers aiming to optimize ESG practices and enhance financial outcomes.
