This paper analyses carbon emissions and value-added embodied in trade between two large developed countries, South Korea and the United States, during 2000-2014. Using multi-regional input-output (MRIO) tables, our analysis reveals that carbon emissions and value-added embodied in exports grew by 19% and 101% for South Korea but shrank by 43% and 7% for the United States. As a result, South Korea experienced a 40% increase in net carbon exports and 243% increase in net valueadded exports. At the industry level, the primary drivers of changes in carbon exports were electricity and basic materials. The majority of industries in witnessed improvements in carbon intensities suggesting improved environmental efficiency. While both countries achieved a decoupling of carbon emissions from value-added exports, substantial year-to-year and sectoral variations were observed. Finally, structural decomposition analysis indicates that domestic supply-side factors played a role in decreasing emissions whereas foreign demand-side factors contributed to emissions increases. In line with the main findings, various implications for policy and future research are discussed. [ABSTRACT FROM AUTHOR]

Background: A joint statement from two federal agencies in the United States calls for coordination and collaboration between programs serving families of infants and toddlers who are at risk or developmentally delayed or disabled U.S. Department of Education and U.S. Department of Health and Human Services. Policy guidance: Joint statement on collaboration and coordination of the MIECHV and IDEA Part C programs. (2017). Individuals with Disabilities Education Act. ED/HHS Joint Guidance Document: Collaboration and Coordination of the Maternal, Infant, and Early Childhood Home Visiting Program and the Individuals with Disabilities Education Act Part C Programs. Young Native American children living on tribal lands in this country are currently eligible for two federal programs associated with these agencies which overlap in mission and implementation. Purpose: This paper outlines potential strategies for creating a more seamless system of services for tribal families involving more centralized intake processes and procedures, cross training of staff to work across programs, and adopting more unifying approaches to program implementation. Conclusion: A streamlined system of services will result in interventions that better support family and child outcomes while reducing duplication of services, consolidating the limited number of qualified professionals available to provide services, and increasing convenience and cultural attunement of services to Native American families currently participating in both programs.

BACKGROUND: With the continuous improvement and progress of the magnetically controlled growing rod technology in the field of the treatment of spinal deformities, numerous studies have been put into this field, but the main research status, hot spots, and development trends are not clear enough. OBJECTIVE: Based on bibliometrics, this paper discusses the quality and quantity of articles in the field of using magnetically controlled growing rods to treat spinal deformities from different countries, aiming to clarify the global development trend of magnetically controlled growing rods and evaluate the research productivity, research trends, and research hotspots in the world. METHODS: The articles published from 1998 to 2023 were retrieved mainly based on the Web of Science database. CiteSpace 5.8 and VOSviewer 1.6.19 software were used to analyze the data and generate a visual knowledge map. The following parameters were evaluated for all studies: the total number of published papers, centrality, h index, the contribution of countries, authors, and journals, and the trend and hot spots were explored through the analysis of co-citation, highly cited literature, and literature keyword explosion. RESULTS AND CONCLUSION: (1) Finally, 138 articles were included. From 2009 to 2020, the number of published articles in this field gradually increased. The United States has the largest number of articles (53, 37.32%), and the United States has the highest h index and centrality of articles. (2) The results of keyword analysis showed that: the top ten keywords, such as early-onset scoliosis, surgery, complications, and so on, objectively and truly reflected the current situation and hot spots of magnetically controlled growing rod in the field of spinal deformity treatment. In recent years, the research focus in this field is the treatment failure caused by risk factors such as the pull-out of the magnetically controlled growing rod, implantation failure, and rod fracture, the accurate use of the corresponding medical classification, the monitoring and treatment of complications such as quality of life and cerebral palsy. (3) The co-citation results showed that: combined with the innovative and effective research of the magnetically controlled growing rod technology, the classification application of spinal deformity and the monitoring and treatment of related complications may be the research trend in this field. (4) Many highly cited articles further emphasized the therapeutic effect of magnetically controlled growing rod technology, providing an effective new idea and technical support for the field of spinal deformity correction. (5) The results of literature keyword explosion analysis demonstrate that the risk factors, medical classification, quality of life, and cerebral palsy of the application of magnetically controlled growing rods may become the research frontier in this field. (6) It can be seen that the application of magnetically controlled growing rod technology in the classification of spinal deformities and the in-depth study of related complications are the development trend in this field, but to further understand the effectiveness and safety of magnetically controlled growing rod technology in the treatment of spinal deformities, we still need long-term follow-up evidence. The overall research level of this field has steadily improved in recent years, but there are also problems such as the small number of high-quality articles and the unbalanced development of research in various regions.

Inadequate sleep is an on-going risk to the health and mission readiness of U.S. Armed Forces, with estimates of sleep problems high above U.S. civilian populations. Intervening early in the career of active duty Air Force personnel (or "Airmen") with education and the establishment of healthy behaviors may prevent short and long term-detriments of sleep problems. This paper describes the results of a qualitative study seeking to understand the facilitators and barriers to achieving good sleep in a technical training school during the first year of entry into the United States Air Force. Using the social ecological framework and content analysis, three focus groups with Airmen were conducted to explore themes at the individual, social, environmental, and organizational/policy level. Overall, results indicated a cohort motivated to achieve good sleep, and also struggling with a number of barriers across each level. This paper highlights opportunities for population health interventions during technical training aimed at supporting Airmen in developing healthy sleep behaviors early in the course of their career.

Background: Dengue virus (DENV) is endemic to many parts of the world and has serious health and socioeconomic effects even in high-income countries, especially with rapid changes in the climate globally. We explored the literature on dengue vector control methods used in high-income, city settings and associations with dengue incidence, dengue prevalence, or mosquito vector densities. Methods: Studies of any design or year were included if they reported effects on human DENV infection or Aedes vector indices of dengue-specific vector control interventions in high-income, city settings. Results: Of 24 eligible sources, most reported research in the United States (n = 8) or Australia (n = 5). Biocontrol (n = 12) and chemical control (n = 13) were the most frequently discussed vector control methods. Only 6 sources reported data on the effectiveness of a given method in reducing human DENV incidence or prevalence, 2 described effects of larval and adult control on Aedes DENV positivity, 20 reported effectiveness in reducing vector density, using insecticide, larvicide, source reduction, auto-dissemination of pyriproxyfen and Wolbachia, and only 1 described effects on human-vector contact. Conclusions: As most studies reported reductions in vector densities, rather than any effects on human DENV incidence or prevalence, we can draw no clear conclusions on which interventions might be most effective in reducing dengue in high-income, city areas. More research is needed linking evidence on the effects of different DENV vector control methods with dengue incidence/prevalence or mosquito vector densities in high-income, city settings as this is likely to differ from low-income settings. This is a significant evidence gap as climate changes increase the global reach of DENV. The importance of community involvement was clear in several studies, although it is impossible to tease out the relative contributions of this from other control methods used. Author summary: Dengue virus is present in many parts of the world and has serious health and socioeconomic effects even in high-income countries, especially with rapid changes in the climate globally. In this study, we explored the literature on dengue vector control methods used in high-income, city settings and associations with number of human dengue infections, and the density of mosquitoes. We found 24 papers with relevant results. Most of these described studies in the United States or Australia. Most were about various forms of biological or chemical control of the mosquitoes. Few papers discussed effects on human dengue infection. We were unable to draw any clear conclusions on how effective mosquito control methods were as we could identify little research on this subject in this specific setting. More research is needed on this topic, particularly as climate change will make more areas of the world vulnerable to dengue infection. [ABSTRACT FROM AUTHOR]

TEACHER leadership , *SCHOOL improvement programs , *TEACHING - Abstract
Given discourse across the globe on school reform and the importance of teachers' work to school improvement, teacher leadership represents an opportunity to re-imagine school cultures, and to consider a range of factors that impact the teaching profession and contribute to overall school improvement. Based on a qualitative inquiry of 24 teacher leaders across two country contexts (Jamaica and the United States) and using the metaphor of 'awakening the sleeping giant', we argue that teacher leadership is an untapped phenomenon and a necessity for 21st century school improvement. Within this paper we draw on the teacher leaders' stories to provide an understanding of the power and resources residing in the domain of teachers' work. Through the findings we showcase that there are elements of teacher leadership that transcend specific school and country contexts based on school structure and historical precedents. The findings presented in this paper also highlight that teachers' work is highly political and that historical precedents related to power and gender created differences in how teacher leadership has been perceived and enacted. The paper closes with a discussion about the cross-cultural 'truths" that emerged and the implications for teachers' work and school improvement. [ABSTRACT FROM AUTHOR]

Most critics focus on the pain and suffering of the first-generation Vietnamese immigrants depicted in Lan Cao's Monkey Bridge. This paper explores how Cao strategically uses the philosophy of karma in Vietnamese Buddhism to provide a method for alleviating their suffering in this novel. It argues that she employs karma to investigate the origins of the adversity and trauma experienced by the first-generation Vietnamese immigrants, including the pro-American attitude of the early Vietnamese authorities during the Vietnam War, the imperialistic actions of the United States, and the resulting karmic consequences. In addition, they demonstrate, through actions like forming "hui", a way to change their fate and heal their trauma for later generations of Vietnamese immigrants, emphasizing positive transformation of karma. This paper suggests that the Buddhist philosophy of karma provides an effective strategy for Vietnamese American immigrants to reflect on the Vietnam War, overcome adversity, and heal their own trauma.

The canopy height model (CHM) derived from LiDAR point cloud data is usually used to accurately identify the position and the canopy dimension of single tree. However, local invalid values (also called data pits) are often encountered during the generation of CHM, which results in low-quality CHM and failure in the detection of treetops. For this reason, this paper proposes an innovative method, called "pixels weighted differential gradient", to filter these data pits accurately and improve the quality of CHM. First, two characteristic parameters, gradient index (GI) and Z-score value (ZV) are extracted from the weighted differential gradient between the pit pixels and their eight neighbors, and then GIs and ZVs are commonly used as criterion for initial identification of data pits. Secondly, CHMs of different resolutions are merged, using the image processing algorithm developed in this paper to distinguish either canopy gaps or data pits. Finally, potential pits were filtered and filled with a reasonable value. The experimental validation and comparative analysis were carried out in a coniferous forest located in Triangle Lake, United States. The experimental results showed that our method could accurately identify potential data pits and retain the canopy structure information in CHM. The root-mean-squared error (RMSE) and mean bias error (MBE) from our method are reduced by between 73% and 26% and 76% and 28%, respectively, when compared with six other methods, including the mean filter, Gaussian filter, median filter, pit-free, spike-free and graph-based progressive morphological filtering (GPMF). The average F1 score from our method could be improved by approximately 4% to 25% when applied in single-tree extraction. [ABSTRACT FROM AUTHOR]
