El presente estudio tiene como propósito analizar la evaluación de los aprendizajes en estudiantes centrada en el desarrollo de competencias en ciencias naturales, se desarrolla en el nivel de educación básica secundaria en instituciones públicas de la localidad tres del municipio de Santa Marta, departamento del Magdalena (Colombia). La investigación se ubica en el paradigma cualitativo interpretativo, de tipo descriptiva y responde al método fenomenológico. Para la recolección de información se utilizaron dos técnicas: entrevista semiestructurada y grupo focal, por lo cual se aplicaron un guion de preguntas abiertas y una guía predeterminada, respectivamente. Los autores que sustentan el estudio: Mosquera (2020), Maestre (2017), Raven (2018), Rodríguez, Mendoza y Cargua  (2019), Amor, y Serrano (2018), Zornoza-Gallego y Vercher (2021).  El análisis de los datos se hizo a través de la triangulación de éstos, en torno a las subcategorías: concepción, características, estrategias metodológicas y las integradoras, evaluación sumativa y formativa, correspondiente a la categoría evaluación de los aprendizajes centrada en el desarrollo de competencias. Los resultados dan cuenta de algunas debilidades y falencias en el personal docente relacionadas con la poca claridad y escasos conocimientos sobre nociones evaluativas de aprendizajes por competencias. Como conclusión se determinó que existe mayores privilegios para aplicar la evaluación cuantitativa más que la cualitativa, lo que dificulta la evaluación del proceso evaluativo, en el área de ciencias naturales. Se recomendó abrir espacios de diálogos, esencialmente entre los directivos docentes y docentes del área de ciencias naturales y la participación de otros educadores interesados en la temática.
Kinship and Community Responses in the wake of the COVID-19 Pandemic.
Authors: Gilbert Tanwie Talom
Published: March 2024

Commonly referred to as ‘the most important health challenge of our times’, the Corona Virus has had devastating consequences and brought untold sufferings to communities and families around the world. A true example of a global problem, the effects of the corona virus has penetrated every community; big and small, rich or poor, necessitating wide ranging measures and interventions aimed at curbing the spread of the disease. While the World health organization (WHO) has coordinated unified efforts at the global stage, countries have put in place national strategies to deal with the rapid spread of the COVID-19. Prevailing socio-political conditions in Cameroon; the ongoing Anglophone crisis and the instability in the Northwest and Southwest regions of the country greatly dampened the rather timid response of the government of Cameroon to the outbreak of the pandemic. Businesses, non-governmental organizations, villages and individuals have been called into action to provide assistance to complement government efforts in the fight against the pandemic. One such responses has come from Nkwen ‘sons and daughters’ residing both in Cameroon and abroad. The paper assesses the conception, framing, and effectiveness of this community intervention and highlights the role of remittances and strong kinship ties in the fight against covid-19 in the Nkwen village of Bamenda, and Cameroon in general.

Automated design of deep neural networks using performance predictor has become a hot topic in current research. Neural architecture search (NAS) methods can be used to enable automatic design of neural network structures by defining different search spaces, search strategies, or optimization strategies. Evolutionary computation by many researchers as the search strategy for NAS, which is called evolutionary NAS (ENAS) . However, ENAS is time-consuming in evaluating the performance of network structures, which hinders the development of ENAS. Therefore, predicting network architecture performance using performance predictor can improve ENAS search speed and save computational resources. This paper summarizes several ENAS methods that utilize performance predictor, and discusses an outlook on search space, search strategies, and the future directions of ENAS assisted by performance predictor.

Mountains, provide crucial water resources for the development of human society, are the water towers of the world. However, mountain water resources have undergone marked changes in recent decades, posing a threat to sustainable human development. Based on long-term hydrological, meteorological, and related environmental data, this study analyzes the evolving patterns of water resources in China's mountains over the past 50 years using trend analysis methods. The results indicate that surface water resources in China's major mountains have undergone noticeable changes over the past 50 years, with varying trends among different mountains. The Qinghai-Tibet Plateau and Tianshan regions show an overall increasing trend in surface water resources, while the Hengduan Mountains, Taihang Mountains, Qinling Mountains, Changbai Mountains, and Yunnan-Guizhou Plateau have witnessed decreasing trends to varying degrees. Furthermore, there are differences in the primary processes influencing surface water resource changes across various mountains. For example, climate change plays a predominant role in driving surface water resource changes in the high-altitude Qinghai-Tibet Plateau and Tianshan region, while human-related activities exert a stronger impact on surface water resource changes in other mountains. To address the challenges brought about by changes in China's mountain surface water resources, it is crucial to take into full consideration the unique natural environments and social systems of each mountain.
Research on Regional Equity in China􀆳s Large-Scale Selection Examinations:A Study Centered on Imperial Examinations and the National College Entrance Examination(NCEE)
Authors:   The Centre for Imperial Examination and Examination Studies, SUN Yiyuan
Published: March 2024

The imperial examination and the college entrance examination both belong to China􀆳s large-scale selection and examination system, and have played important roles in different historical periods. Before the Sui and Tang dynasties, the sense of regional fairness was initially reflected in the form. of "rural election", but after the establishment of the imperial examination system, the problem of regional fairness gradually worsened and reached its peak in the Ming and Qing dynasties, with the emergence of the split-scroll system and the system of taking scholars from different provinces. On the contrary, when the modern college entrance examination was restored, the differences in higher education enrollment opportunities were mainly due to family background and urban/rural origins, and in the early 21st century, such differences began to be reflected at the regional level, and still exist today, for reasons that include both history and reality. On this basis, we adopt a perspective integration approach to compare the similarities and differences between the imperial examination and the college entrance examination in terms of regional equity, and put forward two suggestions for the reform. of the college entrance examination, which are to set a minimum admission ratio for the disadvantaged regions in terms of external support, and to improve the quality of the higher educationresources in the disadvantaged regions in terms of internal development, in order to gradually solve the problem of regional equity in terms of higher education enrollment opportunities in our country.

Authors:   School of Education and Psychological Science, FENG Jianmin
Published: March 2024

Confucianism has always been the main content of the ancient imperial examinations, and the types and scope of the examination of classics have had a significant role in inducing scholars to study the classics. In the Ming and Qing dynasties, the imperial examinations adopted the mode of selecting one of the five classics as the special classics examination, which not only had a long institutional origin and historical evolution, but also produced the system of marking the classics in the implementation of the operation. In order to better select officials and maintain the feudal rule, based on the numerous disadvantages derived from the long-term operation of the special scripture test, the Qing court adopted the reform. of the mode of trying classics, changing the special scripture test for the five classics and test. This reform. and adjustment of this trial mode has an important and unique historical mirror value for promoting the comprehensive reform. of the college entrance examination in the new era.

The role of high-performance work systems and resilience in employee well-being in the pharmaceutical industry of Ghana
Authors:   , Hanu Charles Ata Kwakuv
Published: March 2024

In a business environment characterised by incessant disruptions, organisations must adopt a system of human resource practice that will enhance employee ambidexterity and employee and organisational resilience, which will eventually culminate in employee well-being. Grounded in the job-demand resource theory (JD-R), this study examines the role of high-performance work systems and resilience in employee wellbeing within the pharmaceutical industry in Ghana. Specifically, the study seeks to examine the effects of a high-performance work system on employee resilience, individual ambidexterity, and organisational resilience; and to establish the influence of employee resilience and ambidexterity on organisational resilience. Further, the study seeks to determine the role of organisational resilience in the relationship between high-performance work systems, employee resilience, employee ambidexterity, and employee well-being; and to develop a management framework for the improved implementation of high-performance. The research follows the explanatory sequential mixed-method approach. The quantitative phase constitutes the dominant part of the mixed method. The quantitative data was based on 324 employees within the Pharmaceutical Manufacturers Association of Ghana. The respondents were sampled using a simple random technique. The qualitative data was generated from 12 participants, who were purposefully sampled, through semi-structured interviews. The quantitative data were analysed using SmartPLS, while the qualitative data was analysed using a thematic method with the aid of Nvivo, a computerised software for analysing qualitative data. Subsequently, the quantitative and qualitative data were integrated during the discussions of the outcomes. The results from the quantitative data reveal that nine out of the twelve hypotheses were confirmed. A high-performance work system was found to be positively and significantly related to employee and organisational resilience, exploitation and exploration ambidexterity. The outcomes also indicate that exploitative ambidexterity positively and significantly predicts organisational resilience. However, employee resilience and exploration ambidexterity do not. Finally, the results confirm the mediating role of organisational resilience in the relationship between HPWS, exploitation ambidexterity and employee well-being. Most of the qualitative data provides support for, and explains, the statistical outcomes. This study contributes to the literature on employee well-being by applying the jobdemand-resources theory to investigate the effect of high-performance work systems, employee resilience and individual ambidexterity, and organisational resilience, on well-being. The study proposes a management framework and recommends managerial practices that will enjoin pharmaceutical manufacturers’ managers to enhance their organisations’ resilience and the well-being of their employees.

Published: March 2024

The problematic of integration and social inclusion appears to be highly crucial issue under the prism of societal introduction of children and adolescents possessing refugee/forcibly displacement backgrounds. Besides acute accompanying depression, PTSD, other psycho-emotional disorders related directly to previous traumatic experiences (war, armed conflicts, political, economical insecurity/instability, persecution of an individual, discrimination, degrading treatment etc). The necessity to distinguish specific factors of integration/social inclusion of minors with refugee/forcible displacement backgrounds was posed drastically, once the Russian full-scale invasion on the territory of Ukraine took place on February 24, 2022. The war caused a massive influx of Ukrainian refugees/forcibly displaced persons to the territory of particularly European Union. Among newcomers, there is more than 50% of children/adolescents of different age groups. Under the prism of understanding specific features of going through transitional age in case of all ordinary minors, we have decided to lead a research on development of the antisocial personality disorder in case of minor refuge seekers on the territory of the EU, by bringing as an example actually Ukrainian youth. On the basis of our current research, we have distinguished main differences between ordinary transitional period and IDP in children/adolescents with refugee/forcible displacement backgrounds), as well as provided main reasons, which may cause the development of the analyzed disorder in minors in general.

The theme of Cossacks in Shcherbytskyi's work
Authors: Prysiazhniuk Yurii
Published: March 2024

Soviet heritage in Ukraine is not only monuments to Lenin and cultural stereotypes, but also infrastructure and industry. The fact that Ukraine is still a space state is also a Soviet legacy. It is obvious that the complexity and ambiguity of the Soviet past should call for more reflections on various topics related to the USSR. For example, in studies of the "Soviet" period, the modernization approach is practically not used, many topics remain outside the attention of researchers, the main focus is only on negative experiences (repressions, Holodomor, Russification). This is often a criticism not only of the Bolsheviks, but actually of the entire leftist idea and a kind of negative discrediting advance for future leftist organizations and parties in Ukraine. In addition, "Soviet" is often evaluated as something static, non-dynamic, purely negative. But the Soviet Ukraine of Kaganovich and Kosior is not the Soviet Ukraine of Shelest and Shcherbytskyi. There were changes in the average life expectancy of citizens of the republic and the structure of the family. At the same time, the process of Russification of the population intensified, one of the greatest man-made disasters in the history of mankind occurred, and the oppression of dissidents continued.

The elements of the mathematical analysis course occupy a significant place in the school mathematics course. When teaching the elements of mathematical analysis, students acquire a mathematical apparatus that can be effectively used in solving many problems of mathematics, physics and engineering. The use of mathematical analysis methods makes it possible to solve a number of problems, the solution of which is impossible or difficult by elementary methods. Note that the possibilities of mathematical analysis methods are not limited to such tasks. Thus, the language of derivatives and integrals allows us to formulate many laws of nature strictly. In addition, the use of elements of mathematical analysis in solving problems of school mathematics allows you to learn more deeply the basic concepts of the theory being studied. But school textbooks and textbooks pay little attention to these issues. This article also examines the proof of identities using mathematical analysis methods. The article is relevant for specialists, teachers, students, students involved in school mathematics.

Published: March 2024

У статті представлена реалізація об’єктної моделі системи «Інтернет-бронювання готелю» за допомогою середовища StarUML. Досліджуються важливі аспекти використання зовнішніх платформ для розміщення послуг та бронювання готельних номерів, що дозволяють графічно візуалізувати, специфікувати та документувати системи для ефективного розвитку програмного забезпечення. Розробка програмних застосунків різноманітного призначення пов’язана з використанням об’єктно-орієнтованого підходу, який полягає у декомпозиції інформаційних систем на класи – шаблони, на основі яких створюються однотипні екземпляри – і побудові з них ієрархії з використанням відношень композиції та успадкування. З поширенням об’єктно-орієнтованих мов програмування постала необхідність у використанні єдиної уніфікованої мови моделювання (англ. Unified Modeling Language; UML). Об’єктноорієнтована мова UML стала загальновизнаним стандартом (ISO/IEC 19501:2005), який дозволяє описувати структури програмних продуктів та бізнес-процеси. Її використання забезпечує зрозумілість для кожного фахівця, запобігає формуванню двозначностей чи неточностей. Крім цього, уніфіковану мову моделювання легко адаптувати під конкретну задачу [1]. UML є графічною мовою, яку можна використовувати й на папері, і з використанням CASE-засобів (зокрема, Microsoft Visio). За допомогою UML можна детально описати систему, починаючи розробку з концептуальної моделі з її бізнес-функціями та процесами, а також описати особливості реалізації системи, такі як класи, програмне забезпечення системи, схему бази даних. Використовуючи UML, ми також можемо розробляти складні системи швидко і якісно. Сама мова – це, по суті, нотація, яка активно використовується методом для опису розробок. Нотація являє собою збірку графічних об'єктів, що використовуються в моделях [2].

Published: March 2024

Пропонується варіант оцінки достовірності та ефективності використання математичної моделі щодо забезпечення безпеки об’єкту критичної інфраструктури, який включає три етапи. Перший – визначення величини статистичної ймовірності щодо забезпечення безпеки об’єкту, що охороняється, першої (засобів виявлення небезпеки) та другої (засобів знищення небезпеки) групами, яка є відношенням числа збитих повітряних ударних засобів до загального числа засобів, що беруть участь у терористичному впливі. Другий – визначення величини статистичної ймовірності щодо забезпечення безпеки об’єкту, що охороняється, третьою групою що відповідає за засоби ліквідації наслідків, у разі настання небезпеки, яка є відношенням нормативного проміжку часу реакції до наслідків небезпеки приведеного к фактичному часу. Третій – обчислення статистичної ймовірності щодо забезпечення безпеки об’єкту критичної інфраструктури, що охороняється, яка визначатиметься сумою двох перших статистичних ймовірностей. Зростання обчисленої статистичної ймовірності щодо забезпечення безпеки об’єкту критичної інфраструктури, що охороняється, говорить про збільшення ефективності оптимізаційних заходів на об’єкті, що охороняється, а зменшення, навпаки, про зниження їх ефективності.

The aim of the article is to present the factors that influence the quality of effective people management in a team. The characteristics of a “good” manager and the ways and techniques of his work and contact with employees were presented. Attention was drawn to the problems of remote work. Due to the relatively new situation in companies caused by the pandemic, this problem has not yet been sufficiently described in the literature, which makes this topic extremely important. The article also presents the results of a survey conducted in one of the manufacturing companies regarding the evaluation of managers by employees. Based on the obtained research results, it was found that the most important things for employees are responsibility, impartiality and adequate remuneration for the results achieved. Authority is important in a manager’s work, as it influences the effectiveness of people management and increases the accuracy of decisions made. According to the respondents, having authority depends on the knowledge and skills of the manager, and it is strengthened by an objective approach, good organization and work planning.

Published: March 2024

A cirurgia de catarata em pacientes com doenças reumatológicas representa um desafio clínico devido à complexidade e à possível influência das condições reumatológicas no desfecho cirúrgico. As doenças reumatológicas, como artrite reumatoide, lúpus eritematoso sistêmico e espondilite anquilosante, podem afetar a saúde ocular, aumentando o risco de complicações perioperatórias e impactando os resultados visuais pós-operatórios. Além disso, o manejo perioperatório desses pacientes requer uma abordagem multidisciplinar para otimizar os resultados. Objetivo: Avaliar os desfechos da cirurgia de catarata em pacientes com doenças reumatológicas, explorando as taxas de complicações, a eficácia da intervenção e fatores associados aos resultados visuais. Metodologia: A revisão foi realizada de acordo com as diretrizes do PRISMA. Foram pesquisadas as bases de dados PubMed, Scielo e Web of Science para artigos publicados nos últimos 10 anos. Os descritores utilizados foram "cataract surgery", "rheumatologic diseases", "complications", "visual outcomes" e "perioperative management". Os critérios de inclusão foram estudos que relataram resultados de cirurgia de catarata em pacientes com doenças reumatológicas, escritos em inglês, espanhol ou português. Os critérios de exclusão foram estudos com amostras heterogêneas que não permitiam a análise específica desses pacientes, relatos de caso e revisões narrativas. Resultados: Destacou-se uma maior incidência de complicações perioperatórias, como edema macular cistoide e uveíte, em pacientes com doenças reumatológicas. No entanto, a cirurgia de catarata foi geralmente considerada segura e eficaz nessa população, especialmente quando o manejo perioperatório era adequado. Fatores como o controle da inflamação e o uso de terapia imunossupressora foram associados a melhores resultados visuais pós-operatórios. Conclusão: A cirurgia de catarata em pacientes com doenças reumatológicas apresenta desafios específicos, mas é geralmente segura e eficaz quando realizada com uma abordagem multidisciplinar e um cuidadoso manejo perioperatório. Mais pesquisas são necessárias para entender completamente os determinantes dos resultados visuais nessa população e otimizar a gestão clínica.
The cryostratigraphy of thermo-erosion gullies in the Canadian High Arctic demonstrates the resilience of permafrost

Abstract. Thermo-erosion gullies (TEGs) are one of the most common forms of abrupt permafrost degradation. They generally form in ice-wedge polygonal networks where the interconnected troughs can channel runoff water. Although TEG can form within a single thawing season, it takes them several decades for their complete stabilization. While the inception of TEGs has been examined in several studies, the processes of their stabilization remain poorly documented, especially the ground ice patterns that form following permafrost aggradation in stabilizing TEGs. For this study, we investigated the impacts of two TEGs in the Canadian High Arctic (Bylot Island, NU, Canada) on ground ice content, cryostratigraphic patterns, and geomorphology to examine permafrost recovery following thermal erosion in ice-wedge polygonal tundra. We sampled 17 permafrost cores from two TEGs – one still active (since 1999) and one stabilized (>100 years old) – to describe the surface conditions, interpret the cryostratigraphic patterns, and characterize the state of permafrost after TEG stabilization. We observed that although the TEG caused discernable cryostratigraphic patterns, ground ice content and active layer thickness of the TEGs were comparable to measurements made in undisturbed conditions. We also noted that once stabilized, TEGs permanently (at the Anthropocene scale) alter landscape morphology and hydrological connectivity. We concluded that although the formation of a TEG has profound effects on the short/medium term and leaves near permanent geomorphological and hydrological scars in periglacial landscapes, on the long term, High Arctic permafrost can recover and return to geocryological conditions similar to those pre-dating the initial disturbance. This suggests that in stable environmental conditions undergoing natural variability, permafrost can persist longer than the geomorphological landforms in which it forms.

Abstract. During multiple field campaigns, small quasi-spherical ice crystals, commonly referred to as frozen droplets (FDs), and their aggregates (frozen droplet aggregates (FDAs)), have been identified as the predominant habits in the upper regions of deep convective clouds (DCCs) and their associated anvils. These findings highlight the significance of FDs and FDAs for understanding the microphysics and radiative properties of DCCs. Despite the prevalence of FDs and FDAs at the tops of DCCs where they directly contribute to cloud radiative forcing, the detailed single-scattering properties (e.g., scattering-phase function P11 and asymmetry parameter g) of FDs and FDAs remain highly uncertain. This uncertainty is mainly due to insufficient in situ measurements and the resolution of cloud probes, which hinder the development of idealized shape models for FDs and FDAs. In this study, two shape models, the Gaussian random sphere (GS) and droxtal (DX), are proposed as possible representations for the shapes of in-situ measured FDs and FDAs. A total of 120 individual models of GSs and 129 models of DXs were generated by varying their shapes. Furthermore, by attaching these individual models in both homogeneous or heterogeneous manners, three different types and a total of 315 models of FDAs were created: (1) aggregates of GSs; (2) aggregates of DXs; and (3) combinations of GSs and DXs which are called habit mixtures (HMs). The P11 and g of the developed models were calculated using a geometric optics method at a wavelength of 0.80 μm and then compared with those obtained using a Polar Nephelometer (PN) during the CIRCLE−2 field campaign to assess the models. Both individual component ice crystals (i.e., either GS or DX) and homogeneous component aggregates (i.e., either aggregates of GSs or aggregates of DXs) showed substantial differences compared with the PN measurements, whereas the P11 of the HMs was found to match most accurately the in situ measured P11, reducing the differences to 0.87 %, 0.88 %, and 5.37 % in the forward, lateral, and backward scattering regions, respectively. The g of the HMs was found to be 0.80 which falls within the range of the PN measurement (0.78 ± 0.04). The root mean square error for the HM was minimized to a value of 0.0427. It was shown that the novel HMs developed in this study demonstrated better performance than in previous research where HMs were developed indirectly by weighting the calculated P11 of shape models to interpret in situ measurement. The result of this study carries important implications for enhancing the calculation of single-scattering properties of DCCs.
Flash flood detection via copula-based intensity–duration–frequency curves: evidence from Jamaica

Abstract. Extreme rainfall events frequently cause hazardous floods in many parts of the world. With growing human exposure to floods, studying conditions that trigger floods is imperative. Flash floods, in particular, require well-defined models for the timely warning of the population at risk. Intensity–duration–frequency (IDF) curves are a common way to characterize rainfall and flood events. Here, the copula method is employed to model the dependence between the intensity and duration of rainfall events flexibly and separately from their respective marginal distribution. Information about the localization of 93 flash floods in Jamaica was gathered and linked to remote-sensing rainfall data, and additional data on location-specific yearly maximum rainfall events were constructed. The estimated normal copula has Weibull and generalized extreme value (GEV) marginals for duration and intensity, respectively. Due to the two samples, it is possible to pin down above which line in the intensity duration space a rainfall event likely triggers a flash flood. The parametric IDF curve with an associated return period of 216 years is determined as the optimal threshold for flash flood event classification. This methodology delivers a flexible approach to generating rainfall IDF curves that can directly be used to assess flash flood risk.
