Antecedents of Travel Advisories on Performance of the Hotel Industry in Kenya: A Case of Five-Star Hotels in Nairobi County

Purpose: The general objective of this study was to examine the antecedents of travel advisories on the performance of the hotel industry in Kenya by focusing on five-star hotels in Nairobi County. The specific objectives that guided the study were to examine the effect of political instability advisory, pandemic advisory and terrorism advisory on the performance of five-star hotels in Nairobi County. Methodology: The explanatory research design was employed in this study. The population of this study were the managers of five-star hotels in Nairobi County and were 426 in total. A stratified sample technique was employed in the study, while Simple Random Sampling (SRS) was used to select samples from each study stratum. The Yamane formula was applied is selecting 206 respondents who made the sample size of the study. The study used primary data that was gathered using self-administered and structured questionnaires. These questionnaires were pilot tested for reliability, and were distributed electronically for data collection. Descriptive and inferential analyses were applied during analysis and both tables and figures were used to display the findings. Findings: The results of the study showed that guest safety was a significant element for guests when choosing a destination to visit. Correlation analysis revealed that there existed a significant and negative statistical association between political instability advisory and hotel performance. The regression coefficients showed that a unit increase in political instability advisory provided resulted in a 37.7% decrease in performance of five-star hotels in Nairobi County. The outcome of the study indicated that hotels observed precipitous declines in occupancy rates during the COVID-19 pandemic. Correlation analysis showed that there existed a significant and negative statistical association between pandemic advisory and hotel performance. Regression coefficients indicated that a unit increase in pandemic advisory provided resulted in a 57.7% decrease in performance of five-star hotels in Nairobi County. The findings of the study revealed that a lack the resources had turned the attention of terrorists to target luxury hotels. Correlation analysis demonstrated that there existed a significant and negative statistical association between terrorism advisory and hotel performance. The study concludes that political incidents had a serious effect on the hotels’ performance compared to natural disasters since guest safety was a significant element when choosing a destination to visit. Unique Contribution to Theory, Policy and Practice: The study recommends the managers of five-star hotels in Nairobi County use available media both digital and traditional to provide factual information to their potential guests during times of political unrest. They need to create flexible corporate policies that would allow them to face new circumstances.

Ethical issues after the earthquake in Turkey: A qualitative study on nurses' perspectives.

After natural disasters, the urgent need for survival and rescue operations for those trapped in the rubble results in a heightened demand for healthcare services. Nurses are pivotal in addressing the consequences of such calamities. Nurses operating in critical conditions encounter numerous challenges, including safety issues and ethical quandaries. The ethical considerations primarily revolve around the limitations, duties, and modified norms of care administered by nurses during disasters, presenting both significant and complex challenges. The study was designed to elucidate the nature and essence of nurses' care experiences and to offer an in-depth depiction of the ethical dilemmas while attending to individuals injured in the earthquake. A descriptive phenomenological design was used in this research. A total of 16 nurses who worked for at least 7 days in field hospitals in any of the earthquake regions after the 2023 earthquake in Turkey participated in the research. The research was conducted between March 13 and March 20, 2023. Data were collected by face-to-face interview method with a semistructured form. The steps of Colaizzi's phenomenological method were used to analyze the qualitative data. The study involved a group of 16 Turkish nurses, aged between 20 and 36 years. Through data analysis, four primary themes, 14 subthemes, and 25 codes were identified. The principal themes derived from the interviews included "humanitarian duties," "non-adherence to ethical principles," "respect for the injured," and "medical errors." In this intricate process, it becomes paramount to enhance support for nurses in the domains of management, education, and psychosocial assistance, thereby nurturing their individual and professional acumen, commitment, and ethical sensitivity. Refining the guidelines and professional standards that encapsulate the principles to be adhered to by nurses in disaster scenarios, coupled with providing comprehensive training in both medical and ethical competencies, represents a significant avenue for advancement. Focused training on crisis management will enable nurses to render ethically informed decisions and bolster their professional proficiency. Natural disasters, including earthquakes, pose significant ethical challenges for healthcare professionals, especially nurses who play a pivotal role in delivering care during these emergencies. Issues such as resource allocation and triage, the duty of care and ensuring continuity of care, informed consent and communication, cultural sensitivity, and providing psychosocial support are critical ethical considerations for nursing policies in earthquake situations. Addressing these ethical issues in nursing policies related to earthquakes is crucial for maintaining the integrity of healthcare delivery, preserving public trust, and ensuring the well-being of both the injured and healthcare providers during times of crisis.

Study on the Damage Characteristics of Red Sandstone Foundation Under Rainfall Infiltration in the Red-Bed Area of the Sichuan Basin—Taking Zhongjiang County as an Example

The Sichuan Basin in China is one of the most concentrated areas of red beds in China. In the red-bed area, abundant rainfall can easily cause natural disasters, such as landslides, mudslides, collapses, and subsidence. This has had a great impact on the safety of people and property and sustainable modernization in the area. Zhongjiang County of Sichuan Province is a typical red-bed area, and red sandstone is one of the main foundation rocks in this area. Under the influence of rainfall, the strength of red sandstone foundation easily decays, causing disasters such as house collapse. Therefore, in order to explore the influence of rainfall on the mechanical properties of red sandstone, this paper takes the red sandstone in Zhongjiang County, Sichuan Province, China, as the research object and conducts acoustic-emission uniaxial compression experiments under different water contents. The strength characteristics, instability precursor characteristics, fracture types, and damage characteristics of red sandstone in different water-bearing states are obtained. The abovementioned results provide a reference for the Zhongjiang County Government to consider the impact of rainfall on the red sandstone foundation during modernization and emergency management.

The measurement of agricultural disaster vulnerability in China and implications for land-supported agricultural resilience building

Climate change has recently induced an increase in natural disasters worldwide, which has affected agriculture, a sector highly sensitive to climatic alterations. The paper measures agricultural disaster vulnerability of China in the period 2000–2020 by establishing vulnerability assessment system, and examines how agricultural infrastructure correlates with agricultural disaster vulnerability by constructing grey relational analysis model. Research results indicate that China's agricultural disaster vulnerability presents an overall decreasing trend during the research period. This is mainly attributed to the decreased disaster exposure and increased adaptability to disaster. Spatially, the agricultural disaster vulnerability in the northeastern, central and southwestern regions of China is higher than other regions. Agricultural transportation and communication infrastructure are found to be more influential to agricultural disaster vulnerability followed by irrigation and power facilities. Implications are proposed to enhance agricultural resilience to climate disasters in China.

Being a nurse during an earthquake that affected ten provinces: A qualitative study on experiences and expectations.

This study was conducted to determine the professional experiences and future expectations of nurses working in the most damaged areas during the first two weeks of the 2023 Turkey earthquake. The increase in the frequency and severity of disasters in recent years has strongly shown that nurses must be prepared to respond to all disasters. To prepare for disasters that require a multifaceted approach, the experiences of nurses serving in disasters should not be ignored. A hermeneutic phenomenological approach was used in this research. The study included 18 nurses who worked in the first two weeks of the disaster. Data were collected through semistructured in-depth interviews between April and May 2023. Four themes were identified from the analysis of the data: (1) personal challenges, (2) organizational challenges, (3) nursing during the disaster, and (4) expectations. The results showed that nurses needed psychosocial support intervention skills in disasters and that their psychological preparation and knowledge levels for disasters were insufficient. In addition, the study revealed that organizational preparation was inadequate and that all these factors affected nursing care. The knowledge and skills that nurses need for professional disaster management can be provided by updating undergraduate education, in-service training procedures, and related policies. Considering that ideal disaster management is possible with a multidisciplinary team, it is recommended that national disaster policies be reviewed.

Does drought increase intimate partner violence? Evidence from India

India has a high prevalence of intimate partner violence (IPV) against women. IPV has been observed to increase during natural disasters. Many studies have attempted to unravel the effect of drought on IPV; however, the evidence remains mixed. There is a gap in such studies in the Indian context, and this study seeks to fill this gap. We used data from the National Family Health Survey-4 (NFHS-4) (2015 – 2016) and NFHS-5 (2019 – 2021) to examine the effect of drought caused by the failure of the northeastern monsoon (NEM) in 2016 – 2018. Our analysis included data from 19 states and Union Territories of India (N = 34,590) in a difference-in-differences setup to evaluate the effect of the NEM drought on IPV. Exposure to the NEM drought was positively associated with physical violence (PV) and emotional violence, with results significant at the 95% and 99% confidence levels, respectively. A subsample analysis of rural and urban populations revealed that drought is significantly associated with an increase in sexual violence in urban areas, whereas it correlates with PV in rural areas. Additionally, exposure to drought is linked to a considerable rise in the controlling behavior of partners, for example, “He (is/was) jealous or angry if you (talk/talked) to other men,” “he (does/did) not permit you to meet your female friends).” These findings call for a two-fold policy action: providing support in the form of wage employment programs, subsidies, and other financial assistance during drought periods to help households cope with financial stress and implementing awareness programs aimed at changing partners’ mindsets, thereby reducing controlling behaviors in marriages.

RETROSPECTIVE ANALYSIS OF DESIGNING ANTI-CORRUPTION ACTS AT DIFFERENT LEVELS OF INTERNATIONAL LEGAL ANTI-CORRUPTION

It has been established that international legal countermeasures against corruption are carried out at three levels: global (by the United Nations, the Organization for Economic Cooperation and Development, the World Bank, etc.); regional integration (Council of Europe, European Union, other integration associations); bilateral intergovernmental and interagency cooperation. There is no coordination of directions and means of combating corruption between them. Therefore, international anti-corruption activities at all three levels developed not only in different directions, but also in many ways spontaneously. It has been proven that the wide participation of international organizations in the fight against corruption and the variety of anti-corruption legal means used by them contribute to the concentration and coordination of the efforts of states in the fight against corruption. Another positive effect of the acts of international organizations is also noted: drawing the attention of civil society to the tasks of combating corruption, they significantly strengthen the potential for their full solution. On the other hand, the variety of subjects and legal forms of international legal anti-corruption often create legal conflicts between acts operating in this area. Such collisions create, for example, different approaches to defining the concept of corruption. It is noted that the concepts of designing anti-corruption acts, based on the ideas and methods of system design of complex technological processes and objects, are more and more widely used in the law-making practice of international organizations and states of the modern world. Their influence on the legal regulation of social relations is increasing, confirming that at the current stage of socio-economic, technological, informational development, the complication of social relations, the rapid increase in their quantitative parameters and indicators, the growing danger of man-made and natural disasters, the introduction of system design becomes impossible. It is gradually displacing the maximally ineffective under such conditions practices of «industry», «fragmentary», «point», «situational» legal regulation. It has been established that the systematic design of anti-corruption acts primarily involves conducting comprehensive studies of law-making initiatives. In the course of such studies, all factors that may affect the intended sphere (object) of legal regulation must be analyzed; the opinions, positions, and evaluations of not only regulatory and control-supervisory state bodies, but also potential participants in the projected legal relations should be taken into account.

Perceptions of preschoolers and parents on forest pollution

IntroductionAn examination of preschool children’s perceptions and attitudes towards the environment and forests has recently been conducted. However, little research has focused on preschool children’s and their parents’ perceptions of clean and dirty forests. Investigating these perceptions is essential to increase children’s interest in and sensitivity to the environment, thereby fostering their development as responsible individuals who protect the natural world.MethodsThis study aimed to address this knowledge gap by examining the perceptions of clean and dirty forests held by 40 5–6-year-old students and 40 parents, randomly selected from two preschools: one attended by children from high socioeconomic families and the other by children from low socioeconomic families, in a Mediterranean coastal city in southwestern Turkey. A semi-structured questionnaire was used to collect sociodemographic information and perceptions of clean and dirty forests. Additionally, drawing sheets were distributed to the students to illustrate their concepts of clean and dirty forests.ResultsThe results indicated that individuals with higher educational levels had more complex and conscious perceptions of clean forests. Children considered abstract concepts, such as supernatural forces and fossil fuels, while parents focused on awareness and conservation status. Conversely, parents and children with lower levels of education tended to concentrate on more concrete and everyday factors, such as litter and natural disasters. Individuals with higher socioeconomic status generally associated forest cleanliness with conscious behaviors and conservation, whereas those with lower socioeconomic status linked it more with polluting factors.DiscussionThis investigation provides valuable insights into the management and control of local forests by incorporating the perspectives of children and their parents, promoting responsible and sustainable tourism practices.

Examining the relationship between religious volunteering and mental health screeners among firefighters

ABSTRACT Firefighters experience a high level of traumatic incidents in their work. This high level of exposure puts them at risk for trauma-related symptoms. These trauma symptoms include PTSD, suicide risk, alcohol misuse, and depression, and anxiety. Furthermore, repeated exposure has been found to lead to desensitization, flashbacks, irritability, and PTSD. Exposure to natural disasters may also impact ecospirituality. A survey was designed to include the Life Events Checklist, PHQ-9, GAD-7, PCL-5, and the SBQ-R. This survey was administered to firefighters from Northwest Florida in the fall of 2020 and spring of 2021. Participants were found to have higher levels of PTSD, anxiety, depression, and suicidal risk than the general population. Participants were further asked about their volunteering for religious organization activity. A significant relationship was found between volunteering for religious organization and mental health screeners. Religious volunteering predicted lower levels of PTSD symptoms, depression, and anxiety. The effect size was small.

The Impact of the WTO Agricultural Agreement on Developing Countries

Abstract: Agricultural insurance, as an agricultural risk management tool to disperse agricultural risks, compensate farmers' losses and safeguard agricultural production, has become an indispensable part of the agricultural security system in various countries. However, due to the high cost of agricultural insurance, many countries provide financial subsidies for agricultural insurance. This paper introduces the help of agricultural insurance subsidies to countries in World Trade Organization (WTO), summarizes the main features and inadequacies of relevant WTO rules, and analyzes the existing problems of agricultural insurance subsidies from four aspects based on the practice of American agricultural insurance subsidies. The main conclusions of this paper include: first, the rules of agricultural insurance subsidy are limited and the classification is not clear, which seriously harms the agricultural development of developing countries; second, income insurance and natural disaster insurance in premium subsidies are regarded as "green box" tools, which need to meet certain conditions, otherwise there is still the possibility of being regarded as "amber box" tools; third, the current WTO rules on agricultural insurance subsidies are more conducive to the development of developed countries, but the agricultural insurance subsidies in developing countries lag behind and are difficult to implement, and the rules on agricultural insurance subsidies urgently need to be improved. Fourth, the double standards of developed countries and developing countries have caused differences in the classification of agricultural insurance subsidies. Finally, the thesis puts forward some suggestions on the compliance development of China's agricultural insurance subsidies under the framework of WTO rules.

Evaluating the impact of rational emotive behavior therapy on post-traumatic stress in farmers with experiences of natural disaster.

This study was necessary due to the increasing number of cases of natural disasters such as flood, air pollution, erosion, etc in Nigeria, particularly in the Abia state, as well as the accompanying psychological and health issues affecting individuals within families and society as a whole. The study aimed to examine the impact of rational emotive behavior therapy on farmers' post-traumatic stress (PTS) in Abia State, Nigeria. A randomized control trial was conducted in Abia state, with a sample size of 118 farmers with experiences of natural disasters. Two assessments were conducted before the treatment, immediately after the treatment, and 2 months later to evaluate PTS and irrational beliefs among the farmers. The treatment involved a self-developed PTS-focused rational emotive behavior therapy manual, consisting of 12 sessions lasting 60 minutes each, delivered by counseling psychologists trained in rational emotive behavior and family therapies. Data from the pretest, posttest, and follow-up test were analyzed using chi-square, percentage, partial eta squared, and analysis of covariance statistical tools. The results showed no significant gender differences in the socioeconomic status, employment, and debt status of the participants. The rational emotive behavior therapy was effective in reducing PTS caused by the flood among farmers. Gender did not have a significant moderating effect on farmers' experiences with PTS. The study suggested that family health specialists and rational-emotive therapists collaborate with local authorities to provide career counseling services to farmers and establish community-based rational emotive institutes in each state of Nigeria.

Drowning Prevention should be a Public Health Issue in Nepal

Nepal is prone to a range of natural disasters; earthquakes being the most widely recognised one. However, many people are at risk of drowning as the floodings in the autumn of 2024 showed, but this is not recognised enough as a serious public health risk in Nepal. Drowning relates to everyday activities such as bathing and swimming and should be treated as a social and public health problem. The United Nations, particularly the World Health Assembly, has called its member states for accelerating action on drowning prevention. This mini review paper considered literature covering drowning in children in Nepal and Bangladesh over the past decade. It outlines some of the key drowning risks and the need for active prevention with reference to some tested drowning prevention interventions in neighbouring countries in South Asia. Many of such interventions have been designed and implemented in Bangladesh, a densely populated countries with a load of water. It has one of the highest rates of drowning, especially among children in the world. Next, the paper highlights some on-going research in this field, especially our newly started research project in Bangladesh, which is aimed at the prevention of drowning in children under two. Finally, the paper concludes with some of the lessons Nepal can learn in this area from its neighbours.

Prevalence, Correlates, and Impacts of Displacement Because of Natural Disasters in the United States From 2022 to 2023.

Objectives. To quantify the prevalence, correlates, and impacts of displacement because of natural disasters in the United States. Methods. We pooled data across 10 independent survey samples from the Census Bureau Household Pulse Survey from December 2022 to September 2023. Survey questions asked about displacement from home because of natural disasters, duration of displacement, and impacts of disasters. Results. In our weighted sample of 213 234 003 adults, 3 166 500 (1.5%) reported displacement in the past year because of a natural disaster. People of color, sexual and gender minority populations, and those with lower incomes, disabilities, or unfavorable social determinants of health (SDOH) such as food insecurity were more likely to report displacement. Long-term displacement was more common with fires compared with other disasters. Disaster impacts, including food and water shortage, electricity loss, unsanitary conditions, feeling isolated, and experiencing scams, were more common among people of color and individuals with lower education or income. Conclusions. Many people in the United States, particularly from health disparity populations, are displaced because of natural disasters. Addressing SDOH and other vulnerability factors may help improve disaster preparedness and mitigate postdisaster impacts. (Am J Public Health.

Application of Geographic Information System (GIS), for Crisis Management

Natural disasters have always existed as a natural phenomenon throughout the life of the earth. The occurrence of natural disasters such as floods, earthquakes, storms, etc. in most cases have destructive effects on human settlements and heavy casualties on their residents. It has destroyed the buildings and infrastructures of such areas and imposed unfortunate economic and social consequences on cities and countries. Despite many scientific advances, mankind is still not able to prevent and resist these natural events. Natural disaster management and sustainable development are considered an integrated issue today. Due to limited resources, real development will not be possible without integration with disaster reduction programs. Earthquakes as a natural phenomenon do not have adverse results by themselves. What makes this phenomenon a disaster is the lack of prevention and lack of preparation to deal with its consequences. Therefore, one of the most necessary measures is to apply "principles of crisis management". Crisis management measures can be summarized in three parts: 1. Prevention, 2. Response, and 3. Reconstruction. Therefore, the title is the most important discussion in the strategy of reducing the effects of earthquakes. In this research, we seek to find the best location for crisis management support bases in Malair City, which first identified the effective factors and criteria in the location of relief centers during a crisis. Then, the AHP model was used to determine the importance and value of each criterion and effective elements in the decision, and a questionnaire was designed and distributed among experts and specialists. In the next step, the weight of each of the decision criteria and elements was determined using the hierarchical analysis process method and Expert Choice software. Then, using the field method, figures of the studied area were updated and prepared. In the next step, all information layers were converted to raster in the geographic information system (GIS). Finally, using the Index overlay method, the layers were combined. Three locations were suggested as the best locations for crisis management support bases in Malayer City. Among them, two options, one in the eastern part of the city on Molvi Street, and the other in the southern part of the city on Motahari Street, have been proposed as the best options. In terms of accessibility, they are in a good position. An option, that has a lower score, is located in the southeastern part of the city on Sheikh Kilini Street.

Machine Learning for Improving Renewable Energy: Integrating Solar Power for Continuous Operation of Smart Sensors During Natural Calamities

This research tackles the critical issue of ensuring reliable data collection during natural disasters, such as floods, by calibrating and integrating smart sensors with renewable energy systems. Natural disasters often disrupt power supplies, posing significant challenges to the continuous operation and data availability of these sensors. To address this challenge, the study proposes leveraging renewable solar energy as a sustainable and reliable power source for smart sensors. By incorporating solar energy systems, the framework guarantees that sensors remain operational even in extreme conditions, ensuring that crucial environmental data is consistently accessible for rescue and recovery efforts. The research introduces an innovative approach that employs renewable energy to sustain the functionality of smart sensors during disasters. The framework includes models designed to manage uncertainties in disaster scenarios and optimize energy use for sensor operation. Additionally, the machine learning forecasting tool Prophet is utilized to improve the accuracy of predictions related to energy consumption and sensor performance. Prophet’s strength in handling time series data and generating reliable forecasts is vital for this application.

Under which conditions do extreme events support a paradigm shift? Studying focusing events during two centuries of Swiss flood risk management

Extreme weather events affect many areas around the world. How a country or region reacts to it can take many forms. In this article, we concentrate on policy responses, as typically found in laws, acts, or strategies. Recent research in climate change adaptation or environmental governance concluded that the degree of severity of extreme events is a crucial indicator that policy action should be taken. The event alone is a necessary, but insufficient condition for policies to be introduced. In this context, we ask: Which conditions must be at stake so that an extreme event is able to deploy its focal power and induce policy introduction or change? To answer this question, we studied more than two centuries of flood risk management in Switzerland. We relied on qualitative and quantitative data, as well as process tracing techniques, to relate event characteristics, media, political, and policy contexts to policy change in flood risk management. Results indicate that two conditions made floods turn into focusing events and support paradigm shift: high economic damage and a policy subsystem’s actor constellation favorable to change. We are convinced that our results are also replicable for other natural disasters and other countries than only Switzerland.

A comprehensive review of climate information systems in the arid and semi-arid lands (ASALs) of Kenya for enhanced decision-making process

The reality of climate change has had far-reaching effects on climate and weather patterns globally. High carbon emissions have resulted in wildfires causing migration and death from natural disasters such as droughts, floods, and strong winds. Climate change has also led to reduced crop and livestock farming yields, and worsening incidences of hunger and famine. The use of climate information systems (CIS) in the Arid and Semi-Arid regions of Kenya has not been extensively reviewed. This study reviews the use of CIS in Kenya's Arid and Semi-Arid Lands (ASALs) to improve decision-making and adapt to climate change. We reviewed past and present research on Kenya's ASAL counties’ smallholder farmers’ CIS use. National and international attempts to develop early warning systems through CIS to help stakeholders and end users make farm-level decisions were reviewed. Kenya leads Eastern African countries in emphasizing CIS to reduce climate change's effects on sustainable agriculture. In ASAL countries, the gap between CIS information and its applicability for smallholder farmers’ farm-level decisions, low finance, weak infrastructure, and limited capability are major issues. Limited indigenous knowledge integration and the absence of regular updates and end-user co-development were also noted. Despite these obstacles, CIS can improve decision-making, catastrophe risk management, and socioeconomic growth in these places. Tailored CIS solutions are essential to address the specific needs of smallholder farmers in ASAL regions. Improved coordination and leveraging newer technologies are crucial for effective CIS implementation.

13 Child maltreatment in Canada in the time of COVID-19: Experiences of child protection teams

Abstract Background At the onset of the COVID-19 pandemic, there were many fears regarding the effect on children’s wellbeing – specifically with regards to increased exposure to violence and potential for abuse and neglect within their homes. Early experiences of child protect teams (CPT) in the literature from one Canadian tertiary care center revealed a number of adaptations in their child abuse programs such as a move toward virtual assessments. Objectives Our descriptive study seeks to understand the perspectives, practices, and experiences of child protection teams in Canada during the COVID-19 pandemic with regards to: clinical practice, interactions with child welfare organizations and the justice system, team modes of operating and medical education. These lessons can be applied to child maltreatment and neglect clinical practice in the event of future pandemics, natural disasters, and to provide care to rural areas of Canada. Design/Methods Using a web-based, bilingual, mixed methods survey, we asked both quantitative and open-ended qualitative questions to members of CPTs across Canada. Thematic analysis was completed on qualitative responses. We received a total of 11 responses. Results Respondents unanimously reported a decrease in referrals during the COVID-19 pandemic. 64% endorsed the use of new virtual tools. Virtual tools were used to collaborate amongst members of the CPT as well as with external partners (such as child welfare and justice system). Interestingly, there was minimal adaptation of these tools in patient-facing contexts. 57% of respondents foresee these tools to continue being used in a post-COVID-19 context, and 71% see relevance of these tools for use in rural contexts. Respondents reported that virtual clinical discussions changed the way medical education and case discussion in child maltreatment was delivered. Conclusion These findings describe not only the adaptation of child protection teams to the pandemic, but also robust changes to clinical practice, interactions with partner organizations and the justice system, team modes of operating and medical education in child maltreatment and neglect in Canada.

High-Efficiency Microwave Wireless Power Transmission via Reflective Phase Gradient Metasurfaces and Surface Wave Aggregation.

Microwave Wireless Power Transfer (MWPT) technology is crucial for emergency power supply during natural disasters and powering off-grid equipment. Traditional antenna arrays, however, suffer from low energy capture efficiency, difficult impedance matching, complex synthetic networks, and intricate manufacturing processes. This paper introduces a microwave energy receiver design utilizing Reflective Phase Gradient Metasurfaces (R-PGMs) and surface wave energy convergence technology. The design leverages the effective plane wave-to-surface wave conversion capability of R-PGMs to transform incident microwave energy into a surface wave mode, which is then efficiently harvested using a circular energy convergence array before being output to a coupling port. By optimizing R-PGM parameters, an ideal 60° phase gradient distribution is achieved, facilitating the focus of surface wave energy via dispersion characteristics. These components are integrated into a hybrid antenna array, complemented by a matched energy output port structure. Numerical simulations show that this array can efficiently convert microwave energy from plane waves to surface waves, achieving a conversion efficiency of 85.32% and a collection efficiency of 68.26%. Experimental results corroborate these findings, with peak energy collection efficiency reaching 64.68% at 5.8 GHz and an RF-DC conversion efficiency of 42%, confirming the design's efficacy. Compared to conventional methods, this design simplifies the system by avoiding complex combining networks and significantly enhances the efficiency of microwave MWPT.

Integrating Science, Technology, Engineering, and Mathematics (STEM) into Indigenous Education for Sustainability: The Development and Implementation of a Curriculum Based on Disaster Prevention for Young Children

There are differences between Western mainstream culture and traditional Indigenous culture in the way they address sustainable development. The spirit of sustainability has been emphasized and practiced by Indigenous cultures for hundreds or even thousands of years, but it is increasingly disappearing over time due to the threat of natural disasters. It is necessary to recover this practice of sustainable development from its roots in traditional Indigenous knowledge. This study considers the possibility and utility of incorporating science, technology, engineering, and mathematics (STEM) into Indigenous education for sustainability, a topic that has not been addressed by other studies. Based on a literature review, the proposed framework and content for this study focus on Indigenous disaster prevention. The specific topic was chosen to be most relevant to young Indigenous children. STEM indicators from the US next-generation science standards (NGSS) were referenced to create the proposed STEM teaching objectives, which were designed to be specifically appropriate for Indigenous curricula and teaching activities. Additionally, the cultural curriculum model was adopted to reform the Indigenous curriculum and teaching model by utilizing the transformation and social action approaches. Finally, the five-stage learning cycle was used as the framework to implement the curriculum, intertwined with the principles of the spiral curriculum, to co-construct an instructional example of Indigenous education for sustainability for future reference.
