Discovery of a one-sided radio filament of PSR J0538+2817 in S147: escape of relativistic PWN leptons into surrounding supernova remnant?

ABSTRACT We report the discovery of a faint radio filament near PSR J0538+2817 in the NVSS, CGPS, and the Rapid ASKAP Continuum Survey data. This pulsar is plausibly associated with the supernova that gave rise to the Spaghetti nebula (Simeis 147). The structure is one-sided and appears to be almost aligned (within 17 degrees) with the direction of the pulsar’s proper motion, but in contrast to the known cases of pulsar radio tails, it is located ahead of the pulsar. At the same time, this direction is also approximately (within 5 degrees) perpendicular to the axis of the extended non-thermal X-ray emission around the pulsar. No X-ray or optical emission is detected from the filament region, although the end point of the radio filament appears to be adjacent to a filament of Hα emission. We speculate that this structure might represent a filament connecting pulsar wind nebula (PWN) with the ambient interstellar medium filled with relativistic electrons escaping the pulsar nebula, i.e. a radio analogue of X-ray filaments of Guitar and Lighthouse PWNs and filaments of non-thermal radio emission in the Galactic Centre.

Evaluating the extent and impact of the extreme Storm Gloria on Posidonia oceanica seagrass meadows

Extreme storms can trigger abrupt and often lasting changes in ecosystems by affecting foundational (habitat-forming) species. While the frequency and intensity of extreme events are projected to increase under climate change, its impacts on seagrass ecosystems remain poorly documented. In January 2020, the Spanish Mediterranean coast was hit by Storm Gloria, one of the most devastating recent climate events in terms of intensity and duration. We conducted rapid surveys of 42 Posidonia oceanica meadows across the region to evaluate the extent and type of impact (burial, unburial and uprooting). We investigated the significance of oceanographic (wave impact model), geomorphological (latitude, depth, exposure), and structural (patchiness) factors in predicting impact extent and intensity. The predominant impact of Storm Gloria was shoot unburial. More than half of the surveyed sites revealed recent unburial, with up to 40 cm of sediment removed, affecting over 50 % of the meadow. Burial, although less extensive, was still significant, with 10–80 % of meadow cover being buried under 7 cm of sediment, which is considered a survival threshold for P. oceanica. In addition, we observed evident signs of recently dead matte in some meadows and large amounts of detached drifting shoots on the sea bottom or accumulated as debris on the beaches. Crucially, exposed and patchy meadows were much more vulnerable to the overall impact than sheltered or continuous meadows. Given how slow P. oceanica is able to recover after disturbances, we state that it could take from decades to centuries for it to recoup its losses. Seagrass ecosystems play a vital role as coastal ecological infrastructure. Protecting vulnerable meadows from anthropogenic fragmentation is crucial for ensuring the resilience of these ecosystems in the face of the climate crisis.

Surprising diversity of stink bugs (Hemiptera: Pentatomoidea) in a Brazilian ocean beach drift: results of a rapid survey

The insect drift is a natural phenomenon characterized by the passive movement of insects through air or water currents, which influences their dispersal. The phenomenon of insect drift in ocean beaches represents one of the best-known cases. One of the prominent insect group associated with ocean beach drifts is the Heteroptera, commonly known as true bugs, stink bugs, and water bugs. In this brief communication, we present the diversity of stink bugs (Pentatomoidea) obtained from a rapid survey on an insect drift event at Campeche Beach, Florianópolis, Brazil. The survey was conducted on December 02, 2021, along a transect of ~550 meters in the shoreline. A total of 363 individuals were collected. From these, 35 species, 29 genera, and three families were identified. Two species represent undescribed taxa. We found several species that can be considered rare in entomological collections, such as Copeocoris truncaticornis (Stål, 1865) (Hemiptera: Pentatomidae), Capivacius bufo Distant, 1883 (Hemiptera: Pentatomidae), Curatia denticornis Stål, 1864 (Hemiptera: Pentatomidae), and Tibilis subconspersa Stål, 1860 (Hemiptera: Pentatomidae), as well as economically important species such as Diceraeus furcatus (Fabricius, 1775) (Hemiptera: Pentatomidae), Thyanta perdidor (Fabricius, 1794) (Hemiptera: Pentatomidae), and Piezodorus guildinii (Westwood, 1837) (Hemiptera: Pentatomidae). Our results underscore the significance of beach drift events, as they provide valuable opportunities to investigate the hidden diversity within particular taxa, bringing new data while unveiling unknown species. Moreover, the presence of two undescribed species reinforces the importance of researching and documenting drift phenomena for taxonomic purposes, shedding light on insect migration and dispersion patterns.

A Three-Month Internship in the Field of Family Medicine: an Inevitable Shortcut to Training the Human Resources Needed for the Family health Program

The family physician program in Iran was initially implemented in rural areas in 2005 and later expanded to cover urban communities up to 20,000 population(1). In this program, the family physician team serves as the first point of contact for patients within the healthcare system, and the family physician, as the central element of this team, requires competency in various medical and interpersonal areas. However, this program faced challenges that led to inconsistencies in the training of the required workforce. Efforts to strengthen the training of family physicians included introducing programs leading to certification and modular courses. Despite these efforts, challenges such as lengthy training schedules and uncertain outcomes, as well as limited acceptance, led to a lack of appeal for the general physicians(2). Despite the changes in the national general medical education program, in order to address this issue and to announce it in 2017, a national survey was conducted in 2021 to assess the extent of using the capacities of this national educational program to increase the presence of medical students in the healthcare fields. Severe weaknesses in the use of these capacities and the establishment of a family medicine internship program (optional or mandatory) were still observed. In such a way that only 37% of the educational programs of medical schools showed signs of a maximum one-month presence of interns in the field of family medicine (3). The General Medical Education Secretariat of the Ministry of Health began to address and diagnose this problem from the same year. After numerous expert meetings, using the six-element Carnegie model for educational change (4), it moved towards establishing family medicine internships as relatively long-term programs. In the first phase of these changes, it took action to implement a three-month internship in family medicine at 15 medical universities in the country. The elements of the Carnegie six-element model include: identifying problems with a user-centered approach, focusing on performance change, viewing the entire system as a factor in creating the current situation, determining success indicators and measurement methods, regular research for system improvement, and accelerating learning through the formation and enhancement of networked communities(4). Now, nine months after the announcement of these changes in leading universities, a rapid survey conducted at 15 universities shows that the situation of using family medicine educational field has visibly changed. Not only independent one-month family medicine internship programs have been launched in over 90% of these universities, but also more than 60% of these universities report the implementation of two to three-month independent family medicine internships and a range of changes in educational programs for medical students' participation in family medicine even before they start their internship. This rapid pace of change, in conditions where medical universities are facing financial and human resource shortages, indicates the suitability of the change model used to implement changes in the educational program. Certainly, this path has not been without its challenges, including issues such as a lack of physical space and human resources in the field of healthcare, a shortage of faculty members among family medicine, community medicine, and even trained family physicians for education, the high volume of traditional block-based internship programs, the need for an integrated and unified curriculum for a three-month family medicine internship, misinterpretation by some senior university officials regarding the training program in the healthcare system and its comparison to hospital-based training programs, the absence of a defined payment system for family physicians collaborating in education, and the lack of an efficient referral system in most universities involved, as reported by 15 participating universities in the intervention program. However, considering the serious determination of the Ministry of Health and Medical Education to launch an urban family health program and the urgent need for capable personnel to carry out this important task, it seems that, based on the recent rapid survey results, the implemented changes have been able to achieve acceptable results in the short term. According to the implemented planning, it appears that a unified family medicine internship program will be established in all medical universities of the country from the beginning of the 2024 April.

Health Care Trainees' and Professionals' Perceptions of ChatGPT in Improving Medical Knowledge Training: Rapid Survey Study.

ChatGPT is a powerful pretrained large language model. It has both demonstrated potential and raised concerns related to knowledge translation and knowledge transfer. To apply and improve knowledge transfer in the real world, it is essential to assess the perceptions and acceptance of the users of ChatGPT-assisted training. We aimed to investigate the perceptions of health care trainees and professionals on ChatGPT-assisted training, using biomedical informatics as an example. We used purposeful sampling to include all health care undergraduate trainees and graduate professionals (n=195) from January to May 2023 in the School of Public Health at the National Defense Medical Center in Taiwan. Subjects were asked to watch a 2-minute video introducing 5 scenarios about ChatGPT-assisted training in biomedical informatics and then answer a self-designed online (web- and mobile-based) questionnaire according to the Kirkpatrick model. The survey responses were used to develop 4 constructs: "perceived knowledge acquisition," "perceived training motivation," "perceived training satisfaction," and "perceived training effectiveness." The study used structural equation modeling (SEM) to evaluate and test the structural model and hypotheses. The online questionnaire response rate was 152 of 195 (78%); 88 of 152 participants (58%) were undergraduate trainees and 90 of 152 participants (59%) were women. The ages ranged from 18 to 53 years (mean 23.3, SD 6.0 years). There was no statistical difference in perceptions of training evaluation between men and women. Most participants were enthusiastic about the ChatGPT-assisted training, while the graduate professionals were more enthusiastic than undergraduate trainees. Nevertheless, some concerns were raised about potential cheating on training assessment. The average scores for knowledge acquisition, training motivation, training satisfaction, and training effectiveness were 3.84 (SD 0.80), 3.76 (SD 0.93), 3.75 (SD 0.87), and 3.72 (SD 0.91), respectively (Likert scale 1-5: strongly disagree to strongly agree). Knowledge acquisition had the highest score and training effectiveness the lowest. In the SEM results, training effectiveness was influenced predominantly by knowledge acquisition and partially met the hypotheses in the research framework. Knowledge acquisition had a direct effect on training effectiveness, training satisfaction, and training motivation, with β coefficients of .80, .87, and .97, respectively (all P<.001). Most health care trainees and professionals perceived ChatGPT-assisted training as an aid in knowledge transfer. However, to improve training effectiveness, it should be combined with empirical experts for proper guidance and dual interaction. In a future study, we recommend using a larger sample size for evaluation of internet-connected large language models in medical knowledge transfer.

Life-time HIV testing among people who inject drugs in Iran: results from the National Rapid Assessment and Response survey.

HIV testing is recommended for people who inject drugs (PWID). The aim of this study was to determine the prevalence of lifetime HIV testing among PWID and to better understand the predictors for HIV testing in a convenience sample across Iran. This study is a secondary analysis of Iran's National Rapid Assessment and Response survey conducted between October 2016 and March 2017. Analysis includes the 999 people who reported injecting drugs across the capital cities of 21 provinces. Data were collected by using the venue-based application of the Time Location Sampling (TLS) frame. Chi-square tests were used to examine the difference between HIV testing across different quantitative variables. Logistic regression was used to determine the predictors of life-time HIV testing. Analysis was performed using STATA V.12 software with a significance level of 95%. Most participants were male (n = 902, 93.50%), and over half (n = 555, 59.17%) were older than 35 years old. About one-third, (n = 326, 38%) of people interviewed were single and another one-third (n = 251, 29%) reported being divorced. Over two-thirds of participants (n = 678, 69.78%) in this study reported lifetime HIV testing. The results from a multiple variable logistic regression showed people with a university education were more likely to have been previously tested for HIV than illiterate people (OR = 18.87, 95%CI 2.85-124.6, value of p = 0.002). Those individuals who reported ever receiving methadone treatment were 2.8 times more likely to have been tested for HIV than individuals without methadone treatment experience (OR = 2.89, 95%CI 1.53-5.42, value of p < 0.001). Needle syringe sharing in last month, was negatively associated with life-time HIV testing (OR = 0.29, 95%CI 0.17-0.48, value of p < 0.001). Despite Iran's wide availability and access to counseling services for HIV testing in key populations, the proportion of PWID being tested for HIV could be improved. Developing effective strategies to increase people's understanding and awareness of the importance of and need for HIV prevention and familiarity with HIV testing sites is an essential step in increasing HIV testing for this population. Studies on more recent HIV testing are required to better assess and understand the frequency of HIV testing among PWID in Iran.

An integrated infoveillance approach using google trends and Talkwalker: Listening to web concerns about COVID-19 vaccines in Italy

An infodemic is an information epidemic capable of compromising public health. This manuscript proposes an infoveillance method suitable for listening to web concerns on health to develop adequate infodemiological responses based on the World Health Organization indications. In particular, the case of COVID-19 vaccinations in Italy was investigated. Web interest and concern in COVID-19 vaccines over the past week (January 8–14, 2023) was investigated via the websites Google Trends and Talkwalker by searching for appropriate keywords. Thanks to the analysis of related queries and topics, it was possible to determine and examine the most debated topics relating to specific side effects. Emotional reactions regarding COVID-19 vaccines have been negative in varying percentages between 40 and 70 %, depending on the topic discussed. Feelings of alarm, derision, doubt, and anger were common (about 60 %). The concerns were mainly about the effectiveness against recent COVID-19 variants and alleged side effects such as sudden death, tumors, myocarditis, prion disease, and high ferritin. The most used media among those scrutinized was Twitter (over 90 % of interactions). The male audience participated more and showed more negativity than the female one. The age groups mainly involved were the under-45s. This research discussed the combined use of Google Trends and Talkwalker to conduct rapid infoveillance surveys. The results found showed that the web public has many doubts about COVID-19 vaccines, including the appearance of very rare or unproved side effects. Based on the WHO infodemic management strategy, it is essential that this or similar approaches are adopted by health and government authorities to listen to the community and calibrate appropriate infodemiological responses aimed at preserving public health.

Initiation Patterns and Transitions Among Adults Using Stimulant Drugs: Latent Transition Analysis.

The fourth wave of the drug overdose epidemic in the United States includes increasing rates of stimulant-involved overdose. Recent studies of transitions leading to stimulant misuse have shown complex patterns that are not universally applicable because they have isolated individual populations or individual behaviors. A comprehensive analysis of transitions between behaviors and the associations with present-day problematic drug use has not been conducted. This study aims to determine whether adults from the general population who use stimulants initiate use through a heterogeneous combination of behaviors and quantify the association between these typologies with present-day problematic drug use. Individuals who have reported use of any stimulant in their lifetime were recruited from the 2021 Survey of Nonmedical Use of Prescription Drugs Program, a nationally representative web-based survey on drug use, to participate in a rapid follow-up survey about their past stimulant use. Individuals were asked which stimulants they used, the reasons for use, the routes of administration, and the sources of the stimulant. For each stimulant-related behavior, they were asked at what age, between 6 and 30 years, they initiated each behavior in a 6-year time window. A latent transition analysis was used to characterize heterogeneity in initiation typologies. Mutually exclusive pathways of initiation were identified manually by the researchers. The association of these pathways with present-day problematic drug use was calculated using logistic regression adjusted by the current age of the respondent. From a total of 1329 participants, 740 (55.7%) reported lifetime prescription stimulant use and 1077 (81%) reported lifetime illicit stimulant use. Three typologies were identified. The first typology was characterized by illicit stimulant initiation to get high, usually via oral or snorting routes and acquisition from friends or family or a dealer (illicit experimentation). The second typology was characterized by low, but approximately equal probabilities of initiating 1-2 new behaviors in a time window, but no singular set of behaviors characterized the typology (conservative initiation). The third was characterized by a high probability of initiating many diverse combinations of behaviors (nondiscriminatory experimentation). The choice of drug initiated was not a strong differentiator. Categorization of pathways showed those who were only in an illicit experimentation status (reference) had the lowest odds of having severe present-day problematic drug use. Odds were higher for a conservative initiation-only status (odds ratio [OR] 1.84, 95% CI 1.14-2.94), which is higher still for those moving from illicit experimentation to conservative initiation (OR 3.50, 95% CI 2.13-5.74), and highest for a nondiscriminatory experimentation status (OR 5.45, 95% CI 3.39-8.77). Initiation of stimulant-related use behaviors occurred across many time windows, indicating that multiple intervention opportunities are presented. Screening should be continued throughout adulthood to address unhealthy drug use before developing into full substance use disorders.

Characterizing Pulsars Detected in the Rapid ASKAP Continuum Survey

We present the detection of 661 known pulsars observed with the Australian SKA Pathfinder (ASKAP) telescope at 888 MHz as part of the Rapid ASKAP Continuum Survey (RACS). Detections were made through astrometric coincidence and we estimate the false alarm rate of our sample to be ∼0.5%. Using archival data at 400 and 1400 MHz, we estimate the power-law spectral indices for the pulsars in our sample and find that the mean spectral index is −1.78 ± 0.6. However, we also find that a single power law is inadequate for modeling all the observed spectra. With the addition of flux densities between 150 MHz and 3 GHz from various imaging surveys, we find that up to 40% of our sample show deviations from a simple power-law model. Using Stokes V measurements from the RACS data, we measured the circular polarization fraction for 9% of our sample and find that the mean polarization fraction is ∼10% (consistent between detections and upper limits). Using the dispersion-measure-derived distance, we estimate the pseudo-luminosity of the pulsars and do not find any strong evidence for a correlation with the pulsars’ intrinsic properties.

Spatially Intensive Patterns of Water Clarity in Reservoirs Determined Rapidly With Sensor‐Equipped Boats and Satellites

AbstractOptical water quality affects the quantity and spectral composition of underwater light available to photoautotrophs along with light reflected off the water surface. In reservoirs, prominent gradients for optical water quality and clarity measures occur between inlets and outlets, allowing rapid surveys of ecosystem structure across diverse conditions along with tests of relationships between in situ and remotely sensed water indices. We used a sensor‐equipped boat in a clay‐rich subtropical drinking water reservoir to examine continuous spatial patterns of water clarity and the relationship between in‐lake turbidity and normalized difference turbidity index (ndti) from Sentinel 2 imagery acquired on the same date. Over the 62.3 km boat path, surface turbidity varied between 14 and 85 NTU (mean = 30), with highest values in shallower water near the main inlet. Results indicated a strong linear relationship between sensor turbidity and lab‐determined turbidity. A positive relationship between the satellite turbidity index and in‐lake turbidity, combined with a negative exponential relationship between Secchi depth and turbidity, provided a basis for predicting water clarity metrics continuously over the entire lake surface. In this turbid water body, predicted Secchi depth and turbidity over the whole lake had means of 0.22 m and 54 NTU, with 75% of the lake area &lt;0.29 m and &gt;26 NTU. Pursuit of general relationships involving optical properties of water from high‐speed, data‐intensive spatial surveys and remotely sensed surface reflectance facilitates further development of spatially explicit models of aquatic systems.

Factors Related to Employer Health Insurance Contribution During COVID-19 Epidemic in Indonesia

The COVID-19 pandemic impacted all sectors of the world, including business. In fact, the employer faced a collapse, and many employees were determined. Another issue is health insurance, which might change before and during the pandemic. The objective of this study was to examine the factors associated with the employer’s contribution to health insurance during COVID-19. The secondary data, “Rapid Gender Assessment Survey 2021”, was used on 239 employees in Indonesia. The dependent variable in this study was employer contribution to health insurance during the pandemic (yes or no) and the main independent variable was employer contribution before the pandemic. Other sociodemographic variables were also included in the model as controls. This study used univariate, bivariate, and multivariate (binary logistic regression). The result of this study revealed that employers who contributed to health insurance before the pandemic tend to contribute again to health insurance during the pandemic. This study also reviews the legal law, including regulations about national health insurance and employment. The government’s intention is needed to ensure the rights of employees are well realized.

Digital Strategies to Enhance Cultural Heritage Routes: From Integrated Survey to Digital Twins of Different European Architectural Scenarios

This paper focuses on a research project for the acquisition and post-production of digital data to create informative virtual representations and digital twins of different European Cultural Heritage sites. The goal was to establish a reliable database for a multi-scalar web platform, also accessible through extended reality (XR) tools. This initiative aims to support the promotion and management of cultural and historical monuments within the context of European Cultural Routes supported by the Council of Europe. The project involves different case studies spanning European geographic regions, such as the Upper Kama in Russia, the Valencian Routes of Jaime I in Spain, and the Gdańsk fortresses in Poland. The methodology employed in this effort primarily relies on integrated rapid survey techniques. Unmanned aerial vehicles (UAVs) and simultaneous localization and mapping (SLAM) technologies were used for data collection. These methods contribute to the creation of accurate 3D databases and models that transform the cultural routes into a digital format accessible via an informative platform. The actions presented in this paper are part of the European project “PROMETHEUS”, which is funded by the Horizon 2020 program of the European Union. The project involves collaboration between universities and enterprises, fostering inter-sectoral cooperation. Various techniques such as photographic archives, census analysis, and scan-to-BIM (building information modeling) processes are employed to develop this method further. In fact, the ultimate goal of the project is to establish a framework that can be replicated in other cultural contexts, enhancing the digital documentation and valorization of heritage sites.

Ultraluminous quasars at high redshift show evolution in their radio-loudness fraction in both redshift and ultraviolet luminosity

ABSTRACT We take a sample of 94 ultraluminous, optical quasars from the search of over 14 486 deg2 by Onken et al. in the range 4.4 &amp;lt; redshift &amp;lt; 5.2 and match them against the Rapid ASKAP Continuum Survey (RACS) observed on the Australian Square Kilometre Array Pathfinder (ASKAP). From this most complete sample of the bright end of the redshift ∼5 quasar luminosity function, there are 10 radio continuum detections, of which eight are considered radio-loud quasars. The radio-loud fraction for this sample is 8.5 ± 2.9 per cent. Jiang et al. found that there is a decrease in the radio-loud fraction of quasars with increasing redshift and an increase with increasing absolute magnitude at rest frame 2500 Å. We show that the radio-loud fraction of our quasar sample is consistent with that predicted by Jiang et al.,extending their result to higher redshifts.

Non-engineering house damage after the February 25th, 2022 West Pasaman Earthquake

The earthquake that occurred on February 25, 2022 with a magnitude of M6.2 in West Pasaman Regency, West Sumatera has resulted in many losses such as casualties and damages to infrastructure, especially residential buildings. To determine the level of damage to community houses due to the earthquake, a rapid visual assessment survey was conducted with the National Agency for Disaster Countermeasure (BNPB) and 100 Civil Engineering students. The Method used in this survey is based on the Public Work Minister Regulation, which categorizes the damaged houses into 3 categories, namely light, moderate and heavy damage. Based on the results of the assessment, the damage generally occurred on the walls and structural elements of the houses. The damages is caused by human error factors such as lack of planning, poor construction implementation, site selection and selection of quality building materials that were not in accordance with earthquake safe house building standards. One of the efforts to overcome the problem of the damage is to strengthen the house using a ferrocement layer. The level of buildings damage based on the distance from the earthquake center and the implementation of retrofitting on the damaged houses are also discussed in this paper.

Estimation and mapping of soil texture content based on unmanned aerial vehicle hyperspectral imaging

Soil texture is one of the important physical and natural properties of soil. Much of the current research focuses on soil texture monitoring using non-imaging geophysical spectrometers. However there are fewer studies utilizing unmanned aerial vehicle (UAV) hyperspectral data for soil texture monitoring. UAV mounted hyperspectral cameras can be used for quickly and accurately obtaining high-resolution spatial information of soil texture. A foundation has been laid for the realization of rapid soil texture surveys using unmanned airborne hyperspectral data without field sampling. This study selected three typical farmland areas in Huangshui Basin of Qinghai as the study area, and a total of 296 soil samples were collected. Data calibration of UAV spectra using laboratory spectra and field in situ spectra to explore the feasibility of applying laboratory soil texture models directly to field conditions. This results show that UAV hyperspectral imagery combined with machine learning can obtain a set of ideal processing methods. The pre-processing of the spectral data can obtain high accuracy of soil texture estimation and good mapping effect. The results of this study can provide effective technical support and decision-making assistance for future agricultural land planning on the Tibetan Plateau. The main innovation of this study is to establish a set of processing procedures and methods applicable to UAV hyperspectral imagery to provide data reference for monitoring soil texture in agricultural fields on the Tibetan Plateau.

An outbreak of the invasive macroalgae Rugulopteryx okamurae in Alicante Bay and its colonization on dead Posidonia oceanica matte

We report the first occurrence of Rugulopteryx okamurae in Alicante Bay, the northernmost location in the Iberian Mediterranean where this species was detected. Collected specimens were studied using a morphological and molecular approach. A rapid assessment survey was conducted to assess its presence and abundance in the nearest beach-cast and infralittoral areas. The highest abundance was found over dead P. oceanica matte, occupying an important extension in the bay. We found detached fragments of R. okamurae dispersed by local hydrodynamics, accumulating on some tourist beaches in the region. The potential suitability of the Mediterranean for its spread necessitates monitoring programs to study its variation over time and potential impacts on native biota.

Informal modes of social support among residents of the rural American West during the COVID-19 pandemic.

During the first year of the COVID-19 pandemic, federal spending to government safety net programs in the U.S. increased dramatically. Despite this unparalleled spending, government safety nets were widely critiqued for failing to fully meet many households' needs. Disaster research suggests that informal modes of social support often emerge during times of disruption, such as the first year of the pandemic. However, use of formal government programs and informal support are rarely examined relative to each other, resulting in an incomplete picture of how households navigate disaster impacts and financial shocks. This study compares estimates of informal social support to formal government program use in the rural U.S. West, drawing on data from a rapid-response survey fielded during the summer of 2020 and the 2021 Annual Social and Economic Supplement of the Current Population Survey (CPS-ASEC). We find that informal social support systems were, on aggregate, used almost as extensively as long-standing government programs. Our findings highlight the critical role of person-to-person assistance, such as sharing financial resources, among rural households during a disruptive disaster period. Routine and standardized data collection on these informal support behaviors could improve future disaster research and policy responses, especially among rural populations.

Trends and status of rabbit production and research in Zambia

Rabbit production has the potential to help alleviate poverty levels through job creation, income from the sales of rabbits and their products, and a supply of nutritional food, given its urban and peri-urban functionality. However, not much is known about rabbit production and productivity in Zambia. This study is a rapid survey to document rabbit production systems, management practices and provide estimates of rabbit productivity in Lusaka, Zambia. Three production systems (extensive, semi-intensive, and intensive) were determined given the following criteria: breeds and number reared, housing provided, feed supplied, management practices and marketing of rabbits and by-products. Most producers practiced extensive production system, rearing few local and crossbred rabbits fed mostly vegetables, and housing was made of locally available wood materials and or on deep litter. The intensive production system, however, involved purebreds such as New Zealand White (NZW), Chinchilla (CH), California White (CA), Dutch (DU) and Flemish Giant (FG) and their crosses, with numbers ranging between 50 and 100 breeding animals raised in individual metal cages fed hay and pelleted concentrate feed. Mortality was lower given the conducive environment and high management practices that reduced contact with faecal droppings and allowed urine to be collected for sale. The semi intensive production system lies in the middle and is pivotal to improving productivity in the rabbit industry. Mean performances reported were litter size at birth (3.3, 5.2, 6.4), litter weight at birth (105g, 225g, 410g), litter size at weaning (1.9, 4.1, 5.7), litter weaning weight (650g, 1955g, 3256g) and average mature weight (1510g, 2120g, 2825g) for the extensive, semi intensive and intensive productions systems accordingly. The two major challenges were the limited source of breeding animals, which predisposes the sector to a high level of inbreeding and inadequate veterinary care, leading to a high mortality of over 30%. The government is encouraged to develop a national rabbit development programme that will address the above-mentioned challenges.

Pengaruh Penyuluhan CTPS terhadap Peningkatan Pengetahuan Siswa Sekolah Dasar di Kelurahan Sei Mati Medan Labuhan

One of the goals of sustainable development (SDGs) in the next 15 years is to overcome health problems that are still found in society today. One of the indicators of Clean and Healthy Living Behavior is Hand Washing with Soap (CTPS) which is a behavior of washing hands using soap to prevent various diseases. There are still many people who think that CTPS is not important, just as they only wash their hands when their hands are dirty. The purpose of this study was to determine whether there was an effect of CTPS counseling on increasing the knowledge of elementary school students in Sei Mati Village, Medan Labuhan. The data collection method used in this study is the WHO rapid survey method with a cross sectional approach, namely research that is carried out in one time only. The type of research used is descriptive quantitative research. By using a one group pretest and posttest design. The subject of this research is the fourth grade elementary school students in Sei Mati Village. Sampling was carried out using the PPS (Probability Proportional to Size) method and Accidental Sampling as many as 210 students. Based on the research results obtained through the results of the pretest and post-test showed a significant level value of p = 0.000 &lt;0.05, it was concluded that there was a difference between the knowledge of the counseling respondents before and after the counseling. With the hope that students can have an awareness of the importance of conducting CTPS activities to prevent the occurrence of various diseases, especially in children

An evaluation of truncated birth histories for the rapid measurement of fertility and child survival

BackgroundFull birth histories (FBHs) are a key tool for estimating fertility and child mortality in low- and middle-income countries, but they are lengthy to collect. This is not desirable, especially for rapid turnaround surveys that ought to be short (e.g., mobile phone surveys). To reduce the length of the interview, some surveys resort to truncated birth histories (TBHs), where questions are asked only on recent births.MethodsWe used 32 Malaria Indicator Surveys that included TBHs from 18 countries in sub-Saharan Africa. Each set of TBHs was paired and compared to an overlapping set of FBHs (typically from a standard Demographic and Health Survey). We conducted a variety of data checks, including a comparison of the proportion of children reported in the reference period and a comparison of the fertility and mortality estimates.ResultsFertility and mortality estimates from TBHs are lower than those based on FBHs. These differences are driven by the omission of events and the displacement of births backward and out of the reference period.ConclusionsTBHs are prone to misreporting errors that will bias both fertility and mortality estimates. While we find a few significant associations between outcomes measured and interviewer’s characteristics, data quality markers correlate more consistently with respondent attributes, suggesting that truncation creates confusion among mothers being interviewed. Rigorous data quality checks should be put in place when collecting data through this instrument in future surveys.
