Residential wood heat in the US: Results of a survey investigating user behavior and operation of wood heating appliances

Wood is used as a source of primary and secondary heat by millions of people in the US, but many wood stoves emit levels of particulate matter that negatively impact human health and the environment. Modern wood stoves are designed to pass emissions testing required by regulatory bodies and manufacturers may be hindered in their ability to design for the variability of real-world use. User behavior can strongly impact wood heater emissions, and learning about how they are used in real life could inform the future design of cleaner-burning wood heaters. In this study a survey was performed to investigate the habits, needs, and challenges surrounding residential wood heating in the US. Common user characteristics and behaviors are investigated in categories covering heating technology, fuel use and preference, user behavior, and operation. The data collected from 210 completed survey responses can be used to support and refute anecdotal understandings of wood stove use. Results from this study cover wood heater ages and the presence or lack of catalysts. Fuel provenance, type, seasoning, and storage practices are discussed, along with the ways that respondents learned how to use their stoves and their operational practices including reloading, cold start behavior, and use of air controls. The information presented in this paper can be used to inform industry and regulatory groups as to how people use their wood heaters and highlights areas for potential future research.

‘학교 안 전문적 학습공동체’ 특성 분석 및 활성화 방안 모색: 광주광역시 초등학교 중심

Objectives In this study, we analyzed effective cases of teacher professional learning communities in Gwangju's elementary schools to identify common characteristics and explore activation strategies. Methods This study used a systematic approach to explore the characteristics and enhancement strategies of PLCs in schools. It involved analyzing cases and teacher reflections through open coding, and conducting in-depth interviews with experienced PLC teachers. The findings led to strategies for improving and activating PLCs in the school setting. Results Key traits of school-based PLCs include voluntary participation, teamwork, communication, shared learning, and practical application. To activate PLCs, enhance teacher enthusiasm and awareness, and promote peer sharing. Schools should foster shared values, improve leadership support, and encourage innovation. Conclusions School-based PLCs foster a positive cycle where collaborative research and practice drive teaching changes and boost teacher engagement. For this cycle to thrive, individual teacher efforts must be supported by school-level systems and practical policies from the education office.

Facies variations in gravelly cyclic steps deposited from turbidity currents: Miocene fan delta front deposits compared with a modern active fan delta, central Japan

AbstractGravelly cyclic steps formed by turbidity currents have recently been widely recognised in the geological record. However, the comparison between modern and ancient gravelly cyclic steps remains challenging. In this study, the facies variations of gravelly cyclic steps deposited from turbidity currents in an outcrop of Miocene fan delta front deposits in central Japan are compared with the geomorphic evolution of analogous cyclic steps on the active fan delta front in modern geological systems. These cyclic steps share common characteristics in setting, grain size and dimensions, allowing direct comparison between ancient and modern examples. Repeat bathymetric surveys of the modern Kurobe River fan delta have revealed various types of upslope migrating bedforms interpreted as cyclic steps. Most of these are short‐lived due to erosion of thalwegs by powerful surge‐type turbidity currents triggered by slope failures or burial of thalwegs by deposition, possibly from river‐fed hyperpycnal flows. Such erosion and burial events occur annually on the fan delta front, resulting in compensational cycles. Sedimentary facies of the Miocene fan delta front deposits include conglomerate with a gently upslope dipping erosional base, backset‐stratified sandstone and foreset‐stratified sandstone, which are interpreted as deposits of hydraulic jumps in high‐density turbidity currents in scours on the stoss sides of cyclic steps. Parallel‐stratified conglomerate sandstone is an additional component. Although previous facies models of gravelly cyclic steps have focussed on deposits on stoss sides, a comparison of modern and ancient examples suggests that facies on the lee sides could be parallel‐stratified conglomerate sandstone and undulating bedforms, reflecting supercritical flow conditions. The present study also suggests that hyperpycnal and surge‐type high‐density turbidity currents may deposit different types of facies and play different roles in the construction and destruction of cyclic steps. The present study has significant implications for facies models of gravelly cyclic steps.

Crisis management from a relational perspective: an analysis of interorganizational transboundary crisis networks

Abstract Although transboundary crises have gained relevance in an increasingly interdependent world, our understanding of the relational dynamics governing these phenomena remains limited. This paper addresses this knowledge gap by identifying common characteristics across interorganizational transboundary crisis networks and drivers of tie formation in successful structures. For this purpose, it applies descriptive Social Network Analysis and Exponential Random Graph Models to an original dataset of three networks. Results show that these structures combine elements of issue networks and policy communities. Common features include moderately high centralization, reciprocated ties, core-periphery structures, and the popularity of international organizations. Additionally, successful networks display smooth communication between NGOs and international organizations, whereas unsuccessful networks have fewer heterophilous interactions. Transitivity seems to play a role in network success too. These findings suggest that crisis networks are robust structures that reconcile bridging and bonding dynamics, thereby highlighting how evidence from relational studies could guide transboundary crisis management.

Tree-based analysis of longevity predictors and their ten-year changes: a 35-Year mortality follow-up

BackgroundPrior studies on longevity often examine predictors in isolation and rely solely on baseline information, limiting our understanding of the most important predictors and their dynamic nature. In this study, we used an innovative regression tree model to explore the common characteristics of those who lived longer than their age and sex peers in 35-years follow-up. We identified different pathways leading to a long life, and examined to how changes in characteristics over 10 years (from 1979 to 1989) affect the findings on longevity predictors.MethodsData was obtained from the “Tampere Longitudinal Study on Ageing” (TamELSA) in Finland. Survey data was collected in 1979 from 1056 participants aged 60–89 years (49.8% men). In 1989, a second survey was conducted among 432 survivors from the 1979 cohort (40.2% men). Dates of death were provided by the Finnish Population Register until 2015. We employed an individual measure of longevity known as the realized probability of dying (RPD), which was calculated based on each participant’s age and sex, utilizing population life tables. RPD is based on a comparison of the survival time of each individual of a specific age and sex with the survival time of his/her peers in the total population. A regression tree analysis was used to examine individual-based longevity with RPD as an outcome.ResultsThis relative measure of longevity (RPD) provided a complex regression tree where the most important characteristics were self-rated health, years of education, history of smoking, and functional ability. We identified several pathways leading to a long life such as individuals with (1) good self-rated health (SRH), short smoking history, and higher education, (2) good SRH, short smoking history, lower education, and excellent mobility, and (3) poor SRH but able to perform less demanding functions, aged 75 or older, willing to do things, and sleeping difficulties. Changes in the characteristics over time did not change the main results.ConclusionThe simultaneous examination of a broad range of potential predictors revealed that longevity can be achieved under very different conditions and is achieved by heterogeneous groups of people.

Categorization of mHealth Coaching Technologies for Children or Adolescents With Type 1 Diabetes: Systematic Review.

Managing type 1 diabetes in children and adolescents can be difficult for parents, health care professionals, and even patients. However, over the last decades, the quality of services provided to patients with diabetes has increased due to advances in IT. This study aims to comprehensively document the range of IT tools used in the management of diabetes among children and adolescents, with a focus on identifying the technologies most commonly used based on their frequency. In addition, the study aims to explore relevant methodologies for developing diabetes technology and provide valuable information to developers by delineating essential phases of the design process. The literature search was focused on MEDLINE (PubMed), Web of Science, and Google Scholar for relevant studies. Keywords such as "type 1 diabetes," "adolescents," "kids," "mHealth," "children," and "coaching" were combined using Boolean operators. The inclusion criteria were open access, English-language papers published between 2012 and 2023 focusing on patients younger than 18 years and aligned with our research goal. The exclusion criteria included irrelevant topics and papers older than 18 years. By applying the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method, 2080 studies were recognized, and after selection, 33 papers were agreed upon between the researchers. Four primary categories were defined: types of IT, methodology identification, purpose identification, and feature determination. Among these, mobile health (mHealth) apps emerged as the predominant type of information, garnering 27 mentions. In particular, user-centered design was identified as the most prevalent methodology, cited 22 times. The primary purpose of self-monitoring blood glucose values was mentioned 20 times, while patient education was the highest among common characteristics, with 23 mentions. Based on our research, we advocate for developers to focus on creating an mHealth app that integrates gamification techniques to develop innovative diabetes management solutions. This app should include vital functionalities such as blood glucose monitoring, strategies to improve hemoglobin A1c levels, carbohydrate tracking, and comprehensive educational materials for patients and caregivers. By prioritizing these features, developers can enhance the usability and effectiveness of the technology, thereby better supporting children or adolescents with diabetes in their daily management endeavors.

Prevalence and factors associated with the perpetration and victimization of teen dating violence: A systematic review and meta-analysis protocol

Dating violence is a global health problem that affects adolescents physically, psychologically and sexually. During adolescence, there is a high prevalence and negative consequences in both perpetration and victimization, which can vary according to culture, but maintain common characteristics in traditional societies. Factors associated with the perpetration and victimization of gender-based violence among adolescents include gender inequality, discrimination, substance use, parental neglect, peer influence and exposure to family violence. Despite modern criticisms of gender expectations, traditional views that legitimize violence persist. In this sense, the collection of global data on the prevalence and factors associated with dating violence among adolescents could favour comparative studies between Western and Eastern cultures and is fundamental for informing public policies in a globalized world. It is hoped that the results will contribute to expanding scientific knowledge in the area, as well as helping managers and the academic community to target resources, identify risk groups and promote gender equality from adolescence onwards. In this sense, this study aims to globally assess the prevalence and factors associated with the perpetration and victimization of dating violence among adolescents. It is hoped that the results will expand scientific knowledge in this area.

Flawed Fatherhoods in the Cinema of Jaime Rosales: The Father’s Unmet Gaze

Since his beginnings, Jaime Rosales has directed seven feature films: The Hours of the Day (2003), Solitary Fragments (2007), Tiro en la cabeza (A Shot in the Head) (2008), Dream and Silence (2011), Beautiful Youth (2014), Petra (2018) and Wild Flowers (2022). In his films, the maternal-filial bond becomes the strongest factor in the lives of his characters, but in almost all of his films this bond is treated in parallel with paternal-filial relationships –which this research focuses on. Rosales portrays various models of fatherhood, some clearly failed and others in the light of positive construction. This study aims to analyse, through qualitative and filmic analysis, the design and evolution of these characters, to search for a pattern of fatherhood with common characteristics, to determine if it is a personal theme in the films of Rosales, and to investigate cinematographic resources that specifically make an original portrait of fatherhood. In this sense, we discover that in Rosales’ cinema, the father’s gaze hardly meets that of the son, daughter, or couple, and for this, the director uses various visual strategies such as polyvision, the subjective shot, or panoramic shots to ensure that these gazes, in fact, almost never meet.

The Role of Audiovisuals in Counter-Framing Dynamics: A Longitudinal Experiment on Causal Responsibility Attribution

ABSTRACT Opposing the interpretation of a societal problem with a countering framing is a common characteristic of the democratic discourse. While studies on the dynamics of such counter-framing situations point largely toward recency effects, it remains mostly unclear which characteristics of the initial frame influence these recency effects. Taking current developments in news reporting into account—the trend toward audio and audiovisual news—this study suggests that news framed and presented in textual and audio and audiovisual modalities can attenuate recency effects in counter-framing environments. Building upon the long-standing research strand of responsibility framing and theories of multimodal learning, the findings of this longitudinal probability-sample experiment indicate that the recency effects of frames largely endure even if the initial frame is presented in a multi-modality mode.

8684 Lifetime Duration of Amenorrhea Is Associated With Monetary Decision-Making and Hedonic Eating In Females With a Low-Weight Eating Disorder

Abstract Disclosure: F. Plessow: None. M. Wronski: None. M. Rogers: None. M.G. Turley: None. E.R. Golden: None. M. Slattery: None. J.J. Thomas: None. E.A. Lawson: None. M. Misra: None. K.T. Eddy: None. Background: Low estrogen levels and oligomenorrhea are common characteristics in females with a low-weight eating disorder (LWED). In animal models, estrogen status is associated with neural activity in dopaminergic reward pathways affecting reward processing and decision-making. Whether a similar link exists in humans is unknown but important to understand, as reduced reward-driven behavior and an increased delay of gratification driving decision-making hinder recovery from a LWED. To fill this knowledge gap, we studied the relationship between lifetime duration of amenorrhea and hedonic eating and monetary decision-making in a group of females with a LWED. We hypothesized that longer lifetime duration of amenorrhea is associated with reduced hedonic food intake and a smaller delay discounting rate (indicating an increased delay of gratification) in females with a LWED (independent of age and illness severity). Methods: Fifty-six females with a LWED (mean age±SD: 19.84±2.98 years, range: 13.6-23.5 years) and 34 female healthy controls (HC; 19.08±2.41 years, 13.4-22.2 years) underwent a menstrual history to determine the number of missed menses since menarche, Eating Disorder Examination (EDE) to assess ED psychopathology, anthropometric measurements to calculate body mass index (BMI), Cookie Taste Test as a laboratory-based assessment of reward-related eating beyond satiety, and a monetary Delay Discounting Task to determine their delay discounting rate. Between-group differences were tested using Mann-Whitney U-tests, and associations between duration of amenorrhea and caloric intake at the Cookie Taste Test and delay discounting rate in the LWED group were examined using partial Spearman correlations adjusted for age and BMI as a marker for illness severity. Results: By study design, females with a LWED had a lower BMI (17.97±2.16 vs. 21.71±2.57 kg/m2, U=1,802.50, p<0.001, r=0.75) and more pronounced ED psychopathology (EDE Global Score: 2.38±2.50 vs. 0.00±0.00, U=22.50, p<0.001, r=0.83) than HC. They had missed 16.50±22.64 menses since menarche. When controlling for age and BMI, longer lifetime duration of amenorrhea was correlated with lower caloric intake in the Cookie Taste Test (rs=-0.34, p=0.011) and a smaller delay discounting rate indicating an increased delay of gratification (rs=-0.40, p=0.004). Conclusions: This is the first demonstration that lifetime duration of amenorrhea is associated with hedonic food intake and monetary decision-making in females with a LWED, pointing towards a potential role of cumulative estrogen status in reward processing and decision-making in this population. Future research avenues include investigating whether estrogen replacement can increase reward responsiveness and reduce delay of gratification to promote a faster recovery from a LWED.

Comparison analysis of circulating hemocytes in decapod crustaceans

Hemocytes are the primary immune cells of crustaceans. Few comparison studies have been done among different crustaceans and some key parameters of circulating hemocytes have not been investigated. Here, we compared the circulating hemocytes in six decapod crustaceans, Cherax quadrinatus, Procambarus clarkii, Penaeus vannamei, Penaeus monodon, Eriocheir sinensis, and Scylla paramamosain. Although the hemocytes of different species vary in size, they share common morphological characteristics. Based on their morphological features, circulating hemocytes can be basically classified into granular cells (GCs), semi-granular cells (SGCs), and hyaline cells (HCs). In the six decapods analyzed in this study, the proportion of GCs varied from 10 % to 30 %. P. vannamei, P. monodon, and P. clarkii had fewer GCs in circulation than the other three species. Correspondingly, proliferation was detected only in a small portion of cells in P. vannamei, P. monodon, and P. clarkii under physical conditions. The hemocyte renewal rates for P. clarkii, E. sinensis, and C. quadrinatus were 6.1 %, 5.1 %, and 1.5 % per day, while no steady new hemocyte production was found in S. paramamosain within six days. These data give a general picture of the similarities and differences of circulating hemocytes in decapods and provide a base for an in-depth study of their immune system.

Acute Idiopathic Blind Spot Enlargement and Multiple Evanescent White Dot Syndrome

Acute idiopathic blind spot enlargement syndrome (AIBSES) and Multiple evanescent white dot syndrome (MEWDS) are diseases that fall within the same spectrum. They share common characteristics such as affecting young and middle-aged individuals, being mostly unilateral, causing damage to the outer layers of the retina, and leading to blind spot enlargement in the visual field. In AIBSES, lesions are more frequently located in areas adjacent to the optic disc, whereas in MEWDS, they are observed around the central and peripheral vascular arcades. Unlike MEWDS, in AIBSES, visual field improvement is not expected over time. Multimodal imaging methods, including optical coherence tomography, fundus autofluorescence, fundus fluorescein angiography, and indocyanine green angiography, play an important role in diagnosis and follow-up. In both conditions, the optic nerve can appear normal, but it can also be seen with slightly blurred boundaries and edema, and it should be considered in the differential diagnosis of optic neuropathy.

7147 A Retrospective Evaluation of Biochemical and Clinical Criteria of Permanent Hypoparathyroidism After Total Thyroidectomy and Their Associated Outcomes

Abstract Disclosure: D.G. Su: None. S. Tsou: None. W. Shen: None. Q. Duh: None. C. Graves: None. I. Suh: None. Background: Postoperative hypoparathyroidism (hypoPT) is the most common complication of total thyroidectomy and carries long-term morbidity. However, reported incidences vary widely due to nonstandardized measurement practices and absence of a universally accepted definition. This study aims to evaluate various definitions of hypoPT and to identify influencing factors such as diagnosis and operative duration. Methods: We performed a retrospective analysis of patients with a diagnosis of hypoPT (ICD-9: E20, E20.0, E20.8, E20.9, E89.2) between January 2012 and January 2019 at a single large academic institution, and only included those who had underwent a total thyroidectomy six months prior. Definitions based on low parathyroid hormone (PTH) values (PTH < 10 pg/mL), low calcium levels (corrected calcium [Ca] < 8.5 mg/dL or ionized Ca [iCa] < 1.1 mmol/L), and postoperative supplementation (elemental calcium or vitamin D) were evaluated at 6 and 12 months postoperatively. Postoperative hypocalcemic symptoms were graded by disease severity (based on the presence of numbness/paresthesia, muscle spasms/aches, and Chvostek/Trousseau signs). Patient demographics, operative and pathological characteristics, and use of parathyroid autotransplantation were recorded. Results: Of 879 patients with hypoPT ICD-9 diagnoses, 124 (14%) underwent a total thyroidectomy and were included. Our cohort was 64% female with a median age of 52.9 years. Fifty-one patients (41%) had low PTH levels, 49 (39%) had low calcium levels, and only 26 (21%) had both low PTH and calcium. Of 94 patients (76%) with hypocalcemic symptoms, 68 (73%) required long-term calcium or vitamin D supplementation. Twenty-eight (22.6%) patients had either an ED visit or readmission for hypocalcemia postoperatively. One hundred seven patients (86%) had a pathologic diagnosis of malignancy, of which 37% had extrathyroidal extension, 25% vascular invasion, and 36% positive margins. Those who underwent parathyroid autotransplantation (33%) were less likely to meet biochemical definition of hypoPT (p = 0.0312). Dosage of calcium/vitamin D supplementation did not correlate with symptom grade. Conclusions: Postoperative hypocalcemic symptoms and long-term calcium/vitamin D supplementation were the most common characteristics found in our permanent hypoPT cohort. However, substantial heterogeneity in defining postoperative hypoPT exists, with no definition capturing the full spectrum of affected patients. Further research is necessary to develop reliable diagnostic criteria or biomarkers for hypoPT prediction and management. Presentation: 6/2/2024

Study on territory-wide application of low noise road surface in Hong Kong

Hong Kong is one of the metropolitan cities in the world, with highly concentrated road network system and densely populated developments. At times, it is inevitable to build residential buildings near noisy roads, and traffic noise is one of the environmental problems affecting the locals. The Government strives to pre-empt traffic noise issue through planning new road projects or new residential developments. Concerning traffic noise from existing roads, the Government has implemented noise mitigation measures, for instance, to resurface existing roads with Low Noise Road Surface (LNRS) materials, retrofitting of noise barrier or enclosure, to alleviate traffic noise impact. Moreover, the Government is continuously developing and trialing different LNRS materials such as Polymer Modified Stone Mastic Asphalt (PMSMA6) on roads in Hong Kong, which aims for wider application of LNRS. To explore the feasibility and effectiveness of the wider application of LNRS on local roads, the Government has recently conducted a territory-wide study on the application of LNRS on local roads in Hong Kong. This paper attempts to share the common local road characteristics of applying LNRS material and the latest technical findings, such as the effect on population exposure, of the territory-wide study in Hong Kong.

Adaptation to space conditions of novel bacterial species isolated from the International Space Station revealed by functional gene annotations and comparative genome analysis

BackgroundThe extreme environment of the International Space Station (ISS) puts selective pressure on microorganisms unintentionally introduced during its 20+ years of service as a low-orbit science platform and human habitat. Such pressure leads to the development of new features not found in the Earth-bound relatives, which enable them to adapt to unfavorable conditions.ResultsIn this study, we generated the functional annotation of the genomes of five newly identified species of Gram-positive bacteria, four of which are non-spore-forming and one spore-forming, all isolated from the ISS. Using a deep-learning based tool—deepFRI—we were able to functionally annotate close to 100% of protein-coding genes in all studied species, overcoming other annotation tools. Our comparative genomic analysis highlights common characteristics across all five species and specific genetic traits that appear unique to these ISS microorganisms. Proteome analysis mirrored these genomic patterns, revealing similar traits. The collective annotations suggest adaptations to life in space, including the management of hypoosmotic stress related to microgravity via mechanosensitive channel proteins, increased DNA repair activity to counteract heightened radiation exposure, and the presence of mobile genetic elements enhancing metabolism. In addition, our findings suggest the evolution of certain genetic traits indicative of potential pathogenic capabilities, such as small molecule and peptide synthesis and ATP-dependent transporters. These traits, exclusive to the ISS microorganisms, further substantiate previous reports explaining why microbes exposed to space conditions demonstrate enhanced antibiotic resistance and pathogenicity.ConclusionOur findings indicate that the microorganisms isolated from ISS we studied have adapted to life in space. Evidence such as mechanosensitive channel proteins, increased DNA repair activity, as well as metallopeptidases and novel S-layer oxidoreductases suggest a convergent adaptation among these diverse microorganisms, potentially complementing one another within the context of the microbiome. The common genes that facilitate adaptation to the ISS environment may enable bioproduction of essential biomolecules need during future space missions, or serve as potential drug targets, if these microorganisms pose health risks.17AcJHQ5oWAqHhb9n7GQHSVideo

The Quest for Balance: Historical Background of Türkiye-Africa Relations

The potential and problems in Africa have attracted the attention of several actors, including Türkiye, to the continent. This article aims to contribute to the debates surrounding this interest by analyzing common characteristics of Africa-oriented policies. In particular, this analysis focuses on the key parameters that shaped Türkiye’s initiatives through a historical perspective. We argue that the Turkish policy toward Africa revolves around several concepts. Our analysis of Türkiye’s Africa policy decision-making is structured around several guiding principles: a bipartisan approach, maintaining an autonomous policy, a rational and pragmatic approach, as well as mutual affirmation. To examine policy priorities across different periods, primary sources such as parliamentary minutes, election programs, and diplomats’ memoirs were analyzed, alongside periodicals from the Ministry of Foreign Affairs. The consistent principles of Türkiye’s Africa policy include bipartisan support across governments, autonomous decision-making, and a rational, pragmatic focus on economic diplomacy. Mutual recognition and respect for African sovereignty have also been essential, resulting in a positive reception and growing partnerships with African nations.

Spatio-temporal characteristics of heavy precipitation events observed over the last decade on the eastern French Mediterranean coastal area

Study regioneastern part of the French Mediterranean coastal area. Study focusThis work focuses on the heavy precipitation events that have affected the eastern part of the French Mediterranean coastal area over the last decade and the river discharges associated with these events. The aim is to make a throughout analysis of the spatio-temporal characteristics of heavy precipitation events, and to evaluate whether a high flow event is associated with them when looking at river discharges on affected catchments. New hydrological insights for the regionBased on radar-based precipitation grids, 158 heavy precipitation events (HPEs) affected the study area over the period 2007–2020. In addition, 65 % of HPEs were associated with a high flow event (HFE) on one or more gauged catchments. Results show that HPEs were more frequent during the beginning of summer and autumn. A large portion of autumn and winter HPEs were associated with a HFE. Looking at the spatio-temporal characteristics of the HPEs, their mean duration was 20 hours, with 42 % of the events lasting less than 6 hours. Some common characteristics among the HPEs that caused HFEs were identified: all HPEs lasting more than 30 hours and all HPEs with catchment precipitation accumulation above 150 mm were associated with a HFE.

The modified artificial cohort method for three dominant pelagic copepods in the northern North Pacific revealed species-specific differences in the optimum temperature

The most concerning recent ocean changes in temperature issues are known as marine heat waves. Under these conditions, it is important to evaluate the effects of temperature on zooplankton. In this study, we investigated the growth rates of three dominant copepod species (Eucalanus bungii, Metridia pacifica, and Neocalanus plumchrus) in the northern North Pacific under three different temperature conditions (3, 7, and 11°C) using an artificial cohort method. Experimental conditions for 42 hour incubations were set to light intensity and photoperiod corresponding to 50 m depth. The dissolved oxygen solubility after rearing ranged from 69.2% to 102.1%, suggesting sufficient conditions for copepod growth. Chlorophyll a increased in 83% of the experiments, indicating that the food conditions were sufficient for the copepods. The mean proportion of dead specimens evaluated using neutral red was 10.2%, corresponding with the reported values in the field. Thus, it can be concluded that the laboratory-rearing conditions used in this study provided sufficient food, and the only effect evaluated would be that of the three different temperatures. Since the developmental time for each stage is longer than the rearing period, it is important to conduct experiments with a large number of individuals to obtain accurate growth rate results. The specific growth rates of E. bungii and M. pacifica increased with increasing temperature. In contrast, N. plumchrus showed the highest growth rate under moderate water temperature conditions. In terms of weight units (dry, carbon, and nitrogen), the carbon weight-specific growth rates were higher than those of the other two units, a common characteristic of the three species. This reflected lipid accumulation during the late copepodite stages. The interspecies differences in growth rate responses to water temperature reflect species-specific differences in temperature tolerance or the optimum temperature for each species. As E. bungii and M. pacifica reproduce near the surface layer through income breeding, their temperature tolerance or optimum temperature is expected to be high. However, because the reproduction of N. plumchrus occurs in the cold deep layer by using capital breeding, its temperature tolerance and optimum temperature would be lower than those of the former two species.

Implementing the Infectious Diseases Society of America Antimicrobial Stewardship Core Curriculum: Survey Results and Real-World Strategies to Guide Fellowship Programs.

The Infectious Diseases Society of America (IDSA) developed the Core Antimicrobial Stewardship (AS) Curriculum to meet the increasing demand for infectious diseases (ID) providers with AS expertise. Notable diversity in implementation approaches has been observed among ID fellowship programs using the curriculum. We sought to describe individual approaches and develop a curriculum implementation roadmap. We surveyed ID fellowship programs that had previously implemented the IDSA Core AS curriculum. The survey included questions regarding program characteristics, curriculum participants and presentation format, resources and barriers, and implementation strategies. Commonly reported program features were summarized in the context of the self-reported implementation strategies. Implementation guides were developed based on the most common characteristics observed. Of 159 programs that had purchased the curriculum, 37 responded, and 34 (21%) were included in the analysis. The curriculum was primarily taught by AS physicians (85%) and AS pharmacists (47%). The most common conference structure was a longitudinal conference series (32%), and eLearning was the most common presentation format. Limited AS faculty time (76%) and limited first-year fellow availability (62%) were frequently reported as barriers, and dedicated AS curricular time was a resource available to most programs (67%); implementation guides were created for these 3 program features. Programs reported a variety of implementation barriers and resources, with several common themes emerging, allowing for the development of tailored curriculum planners for 3 commonly observed program characteristics. This work will equip fellowship programs with curriculum implementation strategies and guide future enhancements of the IDSA Core and Advanced AS curricula.
