Multi-domain Anomalous Relationships in Heterogeneous Temporal Data
Authors: Ale Tolulope , Janeja Vandana
Published: December 2023

The Arctic region is crucial to global climate stability. However, recent years have witnessed periods of extreme snow and ice melt, with rising temperatures that double the global average. These are not isolated events. They are the result of intricate interconnections across distinct domains. The challenge, therefore, lies not in understanding these individual domains, such as temperature, and radiation, but in decoding the inter-domain relationships inducing these polar anomalies. To address this, our study presents a novel framework aimed at mining these inter-domain relationships to explain such anomalies and the relationship across time series features comprehensively. These features may be selected from the same or different domains. Such anomalous relationships across features could help detect interesting phenomena such as extreme snow melt, and cloud cover and help identify time periods of interest when such relationships are more prevalent. We extracted the anomalous intervals in each domain using the Poisson Distribution model of rSatScan, then leveraged the concept of Direct Overlap and Proximity of anomalies to identify the direct and time-delayed temporal association (delayed correlation) between anomalies across features. The concept helps us understand how events in one domain may be associated with events in another domain during specific time periods using association rule mining. We evaluated our approach using ERA5 reanalysis data, and validated the identified anomalies against ground truth and evaluated the strength of the generated association rules using metrics like confidence and lift. Notably, several of our identified rules were consistent with findings confirmed by domain experts.
Tear Fluid as a Matrix for Biomonitoring Environmental and Chemical Exposures
Authors: Amini Parshawn , Okeme Joseph
Published: December 2023

Purpose: Environmental exposure to hazardous chemicals have been linked to many detrimental health effects. It is critical to have effective biomonitoring methods to monitor the levels of these chemicals in humans to better evaluate key environmental exposures that increase the risk of chronic disease and death. Traditional biomonitoring utilizing blood and urine is limited due to the specialized skills and invasiveness of collecting these fluid samples. The systematic review focuses on the tear fluid, which is largely under-researched, as promising alternative to these traditional fluids. The objective is to evaluate the practicability of using human tear fluid for biomonitoring environmental exposures, highlighting potential pitfalls and opportunities.
Recent finding: Tear fluid biomonitoring represents a promising method for assessing exposures, as participants can conveniently collect tear fluid samples from the comfort of their home. Tear fluid uniquely interfaces with the external environment at the air-tear interface, providing a surface for airborne chemicals to diffuse into the ocular environment and interact with biomolecules. Tear fluid also contains molecules from the internal environment that have travelled from the blood to tears by crossing the blood-tear barrier. Our review shows that tear fluid can be used to identify hazardous chemicals from the external and environment environments and to differentiate between different exposure groups.
Summary: The review provides a critical analysis of the current state of knowledge in tear-based biomonitoring and draws attention to the promise of using the method for noninvasively increasing access to exposure assessment. The method will become acceptable for routine use as more individual and inter lab studies focus on broadly identifying and quantify exposure markers in tears, understanding factors that influence reliability of the method and standardizing the tear fluid method.
Constraining dark matter with gravitational waves from supermassive black hole binaries using Cassini data
Authors:   , Daniel Matthias
Published: December 2023

Supermassive black hole binaries (SMBHBs) are among the most powerful known sources of gravitational waves (GWs). Accordingly, these systems could dominate the stochastic gravitational wave background (GWB) in the micro- and millihertz frequency range. The time until the merger of two SMBHs in the nucleus of a galaxy can be shortened through dynamical friction due to the presence of dark matter (DM) spikes around the SMBHs. To calculate the orbital evolution of individual SMBHBs within the Newtonian approximation, the SMBHBpy code is developed. This work confirms that the GW signals from SMBHBs with DM spikes can be clearly distinguished from those without any matter. Making use of the upper limit on the characteristic strain of the GWB derived from the data of the Cassini spacecraft mission in 2001/2002, a lower limit on the matter density around SMBHBs is derived in this study. The result is subsequently compared with the theoretical density profiles for cold dark matter and self-interacting dark matter spikes.
Ways of expressing emotional reactions as a communicative practice of social media users
Authors: Solomenko Lina
Published: December 2023

Introduction. The current martial law in Ukraine for 1.5 years now requires a study of indirect ways of communication between Ukrainians in the absence of a permanent telephone connection, interruptions in Internet connection, and, accordingly, an urgent need to use the possibilities of online communication with a delayed response.
Relevance and purpose. One of the simplest and most convenient communication practices in social networks and messengers is to mark an emotional reaction, which can be used even in the absence of an Internet connection in a delayed mode. Therefore, it is necessary to study the question of what purpose and how consciously Ukrainian social media users use this communication practice. In view of this, the purpose of our article is to find out the peculiarities of using graphic images to indicate emotional reactions of social media users as a communicative practice, in particular in the current conditions of the full-scale invasion of Russia.
Methodology. To achieve this goal, we used the following methods: searching for scientific sources on the topic of sign-visual communication and analyzing them, describing ways to indicate emotional reactions of users of social networks and messengers, a survey by questioning the target audience (Ukrainians aged 16 and older, divided into 6 age groups who use social networks and messengers) using a Google form that allowed them to choose three answers and/or add their own answer.
Results. The study found that the purpose of using likes for more than 85% of Ukrainian users is to support the author of the post (joy, sympathy, etc.). At the same time, almost 60% of respondents approach the process of marking a post deliberately and consciously.
Conclusions. The novelty of the study is that for the first time an attempt was made to establish the purpose and nature of the use of likes as a communication practice by Ukrainian users of social networks and messengers. The potential significance of the research results lies in the need to conduct educational work on the use of various graphic signs to denote the entire range of emojis within a particular social network or messenger. Prospects for further research are to study other communication practices of Ukrainians within social networks and messengers.
Models of the use of Artificial Intelligence in the context of life practices of Ukrainian youth
Authors: Ryzhko Olena , Krainikova Tetiana , Krainikov Eduard
Published: December 2023

Introduction. Artificial intelligence (AI) technology penetrates into the life practices of young people. At the same time, a problem arises: young people in society, given their psychophysiological features, are the layer, on the one hand, the most adaptable to technologies, and on the other hand, the most vulnerable to them.
Relevance and purpose. AI gives young people a new communicative experience, new grounds for the formation of the Self, new ways of integration into society (or reintegration), which applies not only to the modern world, but also to the future world (education, production, politics, culture). The purpose of the research is to identify the main behavior patterns of young people associated with the use of AI and to determine the specifics of its influence on the life practices of young people.
Methodology. The research methodology is based on theoretical approaches to the study of information society, media audience, media dependence, technical determinism, diffusion of innovations, etc. In September 2023, a preliminary online survey “Artificial Intelligence in Youth Communications” was conducted (66 respondents aged 17–21).
The results. According to the research results, 79% of respondents have experience using AI, but mostly for specific tasks and not systematically. Based on the survey data, six behavioral models of Ukrainian youth related to the use of artificial intelligence were derived and described: 1) “AI as a tool for learning and work”; 2) “AI as a reference source”; 3) “AI as a tool of computer art”; 4) “AI as interlocutor and advisor”; 5) “AI as a tool for finding ideas, planning”; 6) “Not using AI and technophobia”. 21% of respondents do not use AI chats, are not familiar with their functionality and even have signs of technophobia. Currently, AI is not the main way of communication for young people. Young people prefer live communication, as it provides an opportunity to receive empathy and tactile interaction.
Conclusions. AI is a common component of young people’s media consumption. Life practices of young people are highly mediatized, and the use of AI is becoming multitasking. This indicates that in the future, young people are likely to use AI and cyber-reality more and more actively.
Occurrence of Antibiotics in Aqueous Matrices: An Outlook about the Situation in Brazil
Authors: Lima Karla , de Jesus Jany , Nogueira Raquel
Published: December 2023

This review presents data regarding the occurrence of antibiotics in several aqueous matrices in Brazil reported in the last twelve years (from 2010 to 2022). Despite limited research on the topic, Brazil has the highest number of published data on antibiotics in surface water (SW) among Latin American countries. However, these studies primarily focused on the southern and southeastern regions, providing an incomplete picture of antibiotic occurrence in the aquatic environment of the country. Data from 24 papers show the detection of 23 antibiotics in 5 aquatic matrices, including drinking water, ranging from 0.13 ng L-1 to 37.30 μg L−1. Occurrence in SW was the most reported, and sulfamethoxazole was the antibiotic most prevalent and concentrated in this matrix (7112.4 ng L-1). Besides the fact that antibiotics are only partially removed in sewage treatment plants, in Brazil, only 55.8% of the sewage generated is collected, and 80.8% of the collected sewage is treated, which aggravates the release of antibiotics to the aquatic environment. This poses a significant concern due to potential harm to non-target organisms and antibioticresistant bacteria proliferation, worsening global antimicrobial resistance. Given this scenario, regular monitoring to assess the presence of antibiotics and resistant bacteria is crucial, enabling timely interventions and appropriate mitigation measures.

Published: December 2023

Diffuse large B cell lymphoma (DLBCL) is main subtype of primary thyroid lymphoma and can be histologically transformed from a low-grade B-cell lymphoma. The characteristics and treatment guidelines of these particular DLBCL have not been fully established. The mainstay of treatment of primary thyroid DLBCL is multimodality treatment with chemotherapy and radiotherapy. Meanwhile, surgery can be considered only for diagnosis or alleviation of airway compressive symptoms.A 57-year-old female visited our outpatient clinic for recently enlarged long-held anterior neck mass. A thyroid mass compressing the airway and esophagus was identified on imaging, which was diagnosed as MALT lymphoma by excisional biopsy. After staging, the patient underwent total thyroidectomy with regional lymph node dissection for treatment of stage IIE MALT lymphoma and relieving airway compromise symptoms. The final diagnosis was DLBCL transformed from MALT Lymphoma, and chemotherapy was additionally performed. We report this rare experience with a review of literature.

Published: December 2023

Pilomatricoma is characterized by a semi-transparent epidermis, especially pigmented pilomatricoma, containing melanocytes in basaloid cells, which are dark and purple, resembling vessel-derived skin masses. If the vascularity at doppler ultrasound is high before surgery, it may be misdiagnosed.A 10-year-old female patient visited our clinic because of a mass in the right ear triangular fossa. Ultrasonography was performed, and a vascular-origin tumor was suspected because of the high vascularity. The excised mass was diagnosed as pigmented pilomatricoma by a pathologist.Pilomatricoma is mistaken for other masses owing to its various phenotypes. A misdiagnosis can lead to misdirected strategies which can cause delayed treatment and can result in an increase in the size of the pilomatricoma, making the sequalae of surgery more complicated. For proper treatment, careful examination and evaluation are required before surgery.

Published: December 2023

Squamous cell carcinoma of the lip is a common malignant tumor originating from oral cancer. However, unlike other areas, the lips hold significant functional and aesthetic importance as a part of the face. As a result, a tailored approach based on the tumor's size, type, and location is essential. The Karapandzic flap is especially suitable for reconstructing lesions located on the lip, particularly when the size of the cancer is large and other surgical treatments like free flaps are not feasible. It allows for extensive resection beyond the size of the lower lip. In this case, considering the patient's overall condition, successful reconstruction of the lower lip was achieved using the Karapandzic flap.
Migración rural, urbana e internacional hacia Ciudad Sahagún, Hidalgo (México), durante el proceso de industrialización por sustitución de importaciones, 1952-1982
Authors: Olvera Aguilar Jorge
Published: December 2023

En este artículo se brinda un análisis en torno a la migración —tanto interna como internacional— de trabajadores industriales, técnicos y empleados de confianza hacia un polo de desarrollo industrial, Ciudad Sahagún, Hidalgo (México), entre 1952 y 1982, en una tipología de tres clases de migrante: rural, urbano y extranjero. Se emplea una metodología cualitativa y cuantitativa, que ayuda, como herramienta, a entender dicho fenómeno migratorio durante la industrialización por sustitución de importaciones. El estudio tiene como valor un mejor entendimiento y conocimiento, en términos históricos, de las migraciones internas hacia las ciudades industriales durante la segunda mitad del siglo XX en México. Como limitante, tiene la escasez de fuentes primarias para abordar de mejor forma el tema de investigación. Se concluye que la migración local, nacional e internacional hacia Ciudad Sahagún entre 1952 y 1982, si bien generó ciertos conflictos socioculturales y laborales entre los tres grupos migratorios, también brindó las oportunidades de desarrollo económico-laboral que permitieron que por más de tres décadas ese centro industrial y sus empresas generaran tecnologías y productos para la movilidad y el desarrollo del país, mediante la fabricación de carros de ferrocarril, motores, autobuses, tractores y automóviles.
The cascade effect: Are the U.S. economy and global stock markets vulnerable to the collapse of First Republic Bank?
Authors: Omar Abdullah Bin , Akeel Hatem , Khoj Haitham
Published: December 2023

Following the collapse of Silicon Valley Bank and Signature Bank, First Republic Bank collapsed and is considered the second-largest bank failure in U.S. history. These bank runs can have a cascading or contagion effect on other large banks, and U.S. banking crises can flare up again. We examine the effect of the First Republic bank run on top U.S. banks, U.S. stock indices, and global stock indices using standard event study methodology. We report abnormal returns and cumulative abnormal returns for the event day (t = May 01, 2023) and the 10-day event window (t-5 to t+5), respectively, using data from the 120-day estimation window. The results indicate that on the event day, only JP Morgan Bank's returns were negative, while other banks acted as safe havens for investors. No significant change in returns on the event day is observed for U.S. sector indices (except for the healthcare sector) and global stock exchanges, except for the European and Chinese markets. During the event window, the occurrence of the event significantly affects bank returns after the event date, but no significant effect is found before the event date. Similarly, the healthcare and transportation sectors are more affected than other sectors, while the U.S. and Canadian stock markets seem to be more susceptible to the bank run. Overall, the results suggest that the U.S. government should take decisive initiatives to stop the ripple effect and protect the entire financial system.
Theoretical Approaches in Russia to Understanding the Legal Nature of Legal Relations in the XIX – early XX Centuries: Historical and Legal Aspects
Authors: Andreev Yu. N.
Published: December 2023

Relevance. As is known, legal relations play a significant role in law enforcement, legal protection, satisfaction of the vital interests of individuals and legal entities. The study of legal relations, the elucidation of their legal essence, role and place in the system of legal means remains an urgent problem in legal science, despite the long historical development of the doctrine of legal relations in the general theory of law and civil law. In modern jurisprudence, many researchers consider the concept of "legal relationship" as: public relations regulated by the rule of law; legal form of public (actual) relationship; the unity of the legal form and material content. The author of the article set the task to analyze in the historical and legal aspect the scientific views of Russian scientists on legal relations in the 19th early 20th centuries. in order to form their position on the designated topic.

The purpose of the study: to find out in the historical and legal aspect the scientific views of Russian scientists of the 19th early 20th centuries. about legal relations, their subjective and object compositions, content.

Research objectives: to identify the legal approaches of domestic researchers of law of the specified period to understanding the legal nature, subjects, objects and content of legal relations.

Methodology. In the course of the study of the designated topic, such general scientific and private scientific research methods as historical-legal, logical, formal-legal, system-structural and comparative-legal methods were used.

Results. Based on the analysis of the theoretical conclusions of well-known pre-revolutionary lawyers, it was revealed that a significant part of legal researchers considered legal relations as actual relations regulated by the norms of objective law, and the elements of legal relations are subjects, objects, legal rights and corresponding duties. It has been established that there are legal relations as ideal legal models of behavior of subjects of law, and specific legal relations that arise on the basis of legal facts with the participation of specific interested subjects of law, endowed with subjective rights and legal obligations regarding certain objects rights.

Conclusions. Legal relations are social relations settled on the basis of the norms and principles of Russian law, reflecting the unity of the legal form and legal and factual content, with the participation of individuals and legal entities, public legal entities.

Published: December 2023

En Colombia no se ha estudiado ampliamente la función polinizadora de las especies de abejas locales ni los recursos florales de las especies de arvenses y flora asociada al cultivo de aguacate que estas utilizan. Como contribución en este campo, el libro presenta los resultados de cuatro años de investigación en regiones productoras del departamento del Cauca. En particular, se evidencia que conservar los visitantes florales y las abejas polinizadoras locales e introducidas, mediante la preservación de plantas de arvenses y de flora nativa, no solo favorece la polinización en el cultivo, sino que además contribuye a resguardar la diversidad, abundancia y conservación de los polinizadores y enemigos naturales de los insectos plaga. Por lo tanto, identificar las especies de abejas y las plantas de las cuales se nutren constituye un aporte significativo para su conservación y multiplicación, al tiempo que propicia el desarrollo de sistemas productivos de aguacate sustentables y con mejores rendimientos.

BACKGROUND

COVID-19 mitigation behaviors, such as wearing masks, maintaining social distancing, and practicing hand hygiene, have been and will remain vital to slowing the pandemic.

OBJECTIVE

This study aims to describe the period prevalence of consistent mask-wearing, social distancing, and hand hygiene practices during the peak of COVID-19 incidence (August-December 2020) and just before COVID-19 vaccine availability, overall and in demographic subgroups.

METHODS

We used baseline survey data from a nationwide household probability sample to generate weighted estimates of mitigation behaviors: wearing masks, maintaining social distancing, and practicing hand hygiene. Weighted logistic regression explored differences in mitigation behaviors by demographics. Latent class analysis (LCA) identified patterns in mitigation behaviors.

RESULTS

Among 4654 participants, most (n=2727, 58.6%) were female, were non-Hispanic White (n=3063, 65.8%), were aged 55 years or older (n=2099, 45.1%), lived in the South (n=2275, 48.9%), lived in metropolitan areas (n=4186, 89.9%), had at least a bachelor’s degree (n=2547, 54.7%), had an income of US $50,000-$99,000 (n=1445, 31%), and were privately insured (n=2734, 58.7%). The period prevalence of consistent mask wearing was 71.1% (sample-weighted 95% CI 68.8-73.3); consistent social distancing, 42.9% (95% CI 40.5-45.3); frequent handwashing, 55.0% (95% CI 52.3-57.7); and frequent hand sanitizing, 21.5% (95% CI 19.4-23.8). Mitigation behaviors were more prevalent among women, older persons, Black or Hispanic persons, those who were not college graduates, and service-oriented workers. LCA identified an optimal-mitigation class that consistently practiced all behaviors (n=2656, 67% of US adults), a low-mitigation class that inconsistently practiced all behaviors (n=771, 20.6%), and a class that had optimal masking and social distancing but a high frequency of hand hygiene (n=463, 12.4%).

CONCLUSIONS

Despite a high prevalence of COVID-19 mitigation behaviors, there were likely millions who did not consistently practice these behaviors during the time of the highest COVID-19 incidence. In future infectious disease outbreak responses, public health authorities should also consider addressing disparities in mitigation practices through more targeted prevention messaging.

Abstract: The main objective of the project is Heartbeat Sensor is an electronic device that is used to measure the heart rate i.e. speed of the heartbeat. Monitoring body temperature, heart rate and blood pressure are the basic things that we do in order to keep us healthy. In order to measure the body temperature, we use thermometers and a sphygmomanometer to monitor the Arterial Pressure or Blood Pressure. Our idea is to design a Heart Rate Monitor System using Arduino and Heartbeat Sensor. You can find the Principle of Heartbeat Sensor; working of the Heartbeat Sensor and Arduino based Heart Rate Monitoring System using a practical heartbeat Sensor. Monitoring heart rate is very important for athletes, patients as it determines the condition of the heart (just heart rate). There are many ways to measure heart rate and the most precise one is using an Electrocardiography. But the more easy way to monitor the heart rate is to use a Heartbeat Sensor. It comes in different shapes and sizes and allows an instant way to measure the heartbeat
Upper bounds on key rates in device-independent quantum key distribution based on convex-combination attacks
Authors: Łukanowski Karol , Balanzó-Juandó Maria , Farkas Máté , Acín Antonio , Kołodyński Jan
Published: December 2023

The device-independent framework constitutes the most pragmatic approach to quantum protocols that does not put any trust in their implementations. It requires all claims, about e.g. security, to be made at the level of the final classical data in hands of the end-users. This imposes a great challenge for determining attainable key rates in device-independent quantum key distribution (DIQKD), but also opens the door for consideration of eavesdropping attacks that stem from the possibility of a given data being just generated by a malicious third-party. In this work, we explore this path and present the convex-combination attack as an efficient, easy-to-use technique for upper-bounding DIQKD key rates. It allows verifying the accuracy of lower bounds on key rates for state-of-the-art protocols, whether involving one-way or two-way communication. In particular, we demonstrate with its help that the currently predicted constraints on the robustness of DIQKD protocols to experimental imperfections, such as the finite visibility or detection efficiency, are already very close to the ultimate tolerable thresholds.

Authors: Ибрагимов Руслан , Королёв Евгений
Published: December 2023

В статье представлены результаты исследований влияния природы суперпластификаторов на фазовый состав цементного камня, твердевшего 1 и 28 сут. в нормально-влажностных условиях. Установлено, что активация портландцемента в аппарате вихревого слоя снижает содержание непрогидратированных минералов портландцементного клинкера. Количество продуктов гидратации цементного камня, твердевшего в течении дних суток, полученных традиционным образом, убывает при введении добавок: С-3→ SP10→ MF. Совместный помол исследуемых добавок с портландцементом в аппарате вихревого слоя способствует повышению количества продуктов гидратации на 4–35 % в зависимости от вида добавки, и по эффективности их увеличения располагается в ряду: С-3→ SP10→ MF. На первые сутки твердения прочность цементного камня в значительной степени зависит от характеристик кристаллов в цементном камне, при этом прочность цементного камня увеличивается при уменьшении величины приведённого размера блока-мозаики всех идентифицированных фаз цементного камня.

Published: December 2023

В статье рассматриваются факторы, влияющие на целесообразность многоэтажного деревянного строительства в России. На основе анализа зарубежного опыта выделяются возможные тенденции развития архитектуры многоэтажных деревянных гражданских зданий. Выявлены препятствия и недостатки на пути становления данного архитектурно-строительного направления. С одной стороны, актуальность строительства многоэтажных деревянных гражданских зданий обусловлена государственной поддержкой, богатыми традициями деревянного зодчества, необходимостью использования продукции предприятий лесопромышленного комплекса на внутреннем рынке, экологическими, гигиеническими, экономическими, архитектурно-художественными преимуществами. С другой стороны, нельзя отрицать скепсис и опасения в вопросе при-менения древесины в жилых и общественных зданиях высотой пять и более этажей. Цель данной статьи – поднять вопрос о актуальности, целесообразности и перспективах применения древесины в современном гражданском строительстве в России.
INFLUENCIAS DE LAS CLAVES INTERPRETATIVAS DE LA JURISPRUDENCIA CONSTITUCIONAL ESPAÑOLA EN CHILE EN MATERIA DE DERECHO ADMINISTRATIVO Y ADMINISTRACIÓN PÚBLICA
Authors: Camacho Cépeda Gladys
Published: December 2023

El artículo tiene por objeto encontrar el eco de la jurisprudencia constitucional española en la jurisprudencia del Tribunal Constitucional chileno. La constitución española de 1977 es una referencia para las cartas políticas aprobadas con posterioridad. Esta influencia no se ha restringido a la redacción de normas jurídicas, sino que incluye la interpretación que el Tribunal Constitucional español ha hecho de las disposiciones constitucionales. Este trabajo analiza esa influencia en el Tribunal Constitucional chileno, a través del estudio de sentencias chilenas que citan las decisiones del Tribunal Constitucional español. Se plantea que, dados los lazos históricos que ambos países comparten, no debe sorprender la influencia de la jurisprudencia constitucional española en Chile en temas relativos al Derecho administrativo y la administración pública.

Published: December 2023

Poor women in Indonesia are vulnerable to various economic problems. This research was conducted to reveal and analyze how batik craftswomen in Indonesia who live in poverty must have a dual role in supporting their families. This research was conducted using a qualitative method with an explanatory design model. The data was collected through in-depth interviews with various informants and direct observation of batik activities carried out by women in several regions in Indonesia. Document collection is also carried out on other relevant data sources and references. The results show that batik craftswomen in Indonesia who are in poor conditions have tried to improve their quality of life through excessive roles. Apart from being housewives, these women also earn a living by working in more than one field, such as farming and batik. However, the income from these multiple jobs does not make them free from poverty because the income from batik is low and not feasible. This insufficient income is used to fulfill their own needs and the needs of their husbands and children. Even though they have multiple jobs, batik craftswomen are still in poor economic conditions.

Authors: Gulab Fozia
Published: December 2023

This study explored the perceptions of administrators, teachers and students of secondary schools in Karachi-Pakistan regarding the strategies adopted by the schools to exhibit care for the learning of students. This qualitative multisite case study was conducted with schools under the administration and management of Christians and Ismailies.   A semi-structured interview guide was used as a tool for data collection purposes. The data were transcribed and coded for the construction of themes.  Themes such as teacher preparation and performance, communication with parents, a learning-conducive environment, curricula supporting activities and continuous professional development were constructed from the data analysis. The study findings reveal that schools have adopted various strategies to facilitate and support students' learning. However, the primary focus seems to be on cognitive development, often at the expense of paying adequate attention to physical, social, and emotional development. Hence the study suggests that assumed and expressed needs of students in areas other than the cognitive domain should be considered pivotal by the school for a safe and peaceful society. The study also suggests that the application of care in a practical sense is the need of the times and should be made a systemic reality for all schools in Pakistan.
