Research connects health outcomes to hazard exposures but often neglects the nature of the exposure or repeated events.
Methods
We undertook a cross-sectional study (N = 1,094) from a representative sample in the Houston Metropolitan Statistical Area (HMSA). Respondents were recruited using Qualtrics panels, targeting individuals reflecting the population of the HMSA. Physical composite scores (PCS) were calculated using the SF-12v2.
Results
Among the hazards (hurricanes, flooding, tornadoes, chemical spills, industrial fires), only chemical spills showed a dose-response: physical health scores declined significantly with repeated exposures. This decline persisted after multiple linear regression. Covariates including sex, race, age, education, and chemical exposure affected PCS, but chemical spill exposure remained the most significant, negatively affecting PCS even after adjusting for other factors (coef =–2.24, 95% CI, –3.33 to –1.15).
Conclusion
Grasping the effects of hazards, especially repeated ones, can guide emergency management in mitigation, recovery, and preparedness efforts.
Globally, women experience poverty at disproportionate rates to men, with the situation being worse for Indigenous women and women of colour. Social security systems are one avenue for income redistribution that can alleviate poverty. However, such systems are themselves embedded within and produced by unequal social relations, meaning they can also serve to perpetuate and exacerbate social inequalities. This is exemplified under neoliberal welfare reforms, which have disproportionate negative impacts for women across the world (e.g. increased poverty and stigma, reduced health/wellbeing, and more). Again, this is particularly the case for Indigenous women and women of colour.
In this article, we offer an intersectional feminist analysis of an intensive form of neoliberal welfare conditionality, Australia’s ‘compulsory income management’ program (CIM). CIM quarantines social security incomes onto cashless bank cards to restrict expenditure to ‘approved’ items. Drawing on interviews and surveys with 170 individuals who have personally experienced CIM, we show that it has myriad negative impacts that are especially borne by (Indigenous) women. These are not, we argue, unintended policy impacts, but are instead symptomatic of the gendered and racialised violence that is woven into patriarchal capitalism more broadly. Thus, the experience of CIM holds lessons for welfare states internationally.
The previously unindexed laboratory X-ray powder diffraction data of mosapride dihydrogen citrate dihydrate, an API used to stimulate gastrointestinal motility, has been recorded at room temperature. Using these data, the crystal structure of this API has been refined in space group P21/c (No. 14) with a = 18.707(4) Å, b = 9.6187(1) Å, c = 18.2176(4) Å, β = 114.164(1)°, V = 2990.74(8) Å3, and Z = 4. The structure of this material corresponds to the phase associated with CSD Refcode LUWPOL determined at 93 K. The Rietveld refinement, carried out with TOPAS-Academic, proved the single nature of the sample and the quality of the data recorded.
To ensure whether spaced education, which increases long-term knowledge retention, could be integrated into auditor competency assessment.
Design:
Quality improvement project.
Setting:
Academic, freestanding children’s hospital.
Participants:
Hand hygiene (HH) auditors.
Intervention:
We enrolled trained HH auditors in an online spaced-education platform to assess mastery of knowledge, delivering 46 unique questions at spaced intervals followed by rationale; we retired questions after 3 correct answers. An e-mailed 10-item survey gauged participant satisfaction with the program. The Wilcoxon signed-rank test was used to compare change in median knowledge score from first to final attempt.
Results:
A total of 12,120 questions were attempted by 126 auditors, and 49 (39%) completed the entire course. Median knowledge score increased significantly by 10.5 percentage points (IQR 4–15) between first and final attempts (P < 0.001). Thirty auditors (27%) responded to the survey. The majority agreed the number and complexity of questions were appropriate (57% and 67%, respectively). Eighty-seven percent reported the platform easy to navigate, and 77% agreed adequate time was provided for completion. Free-text suggestions included delivering fewer questions at a narrower spacing interval over a shorter time frame because of competing work demands.
Conclusions:
Auditor knowledge of HH indications and technique is critical to ensuring data validity. A spaced-education competency program improved HH auditor knowledge in the short term. Completion rate was low, and some participants expressed a desire for fewer questions over a shorter time frame. This study offers insight into ways to optimize spaced education as a potential tool for HH competency assessment.
Patients undergoing maintenance hemodialysis face heightened vulnerability during disasters like tropical cyclones, yet there is sparse research on their treatment-related challenges and countermeasures. This scoping review aims to highlight the issues maintenance hemodialysis patients encounter following tropical cyclones.
Methods
A systematic scoping review of 19 articles from 2000 to 2023 was conducted, evaluating eligibility against predefined criteria.
Results
Hemodialysis patients encounter substantial challenges during and after tropical cyclones in the United States, Puerto Rico, Australia, and Taiwan. Thematic analysis identified 3 themes related to “challenges” (Hemodialysis health-related challenges, socially relevant challenges, and challenges of management inefficiencies). “Recommendations” comprised 4 themes and 4 phases across the “mitigation phase” (fortifying healthcare infrastructure and mobilizing community-focused risk mitigation initiatives), “preparedness” (emergency plan development, training, and patient education), “response” (activation of emergency plans and providing emergency healthcare services), and “recovery” (intersectoral collaboration for recovery and rebuilding).
Conclusion
This scoping review underscores challenges confronted by patients undergoing maintenance hemodialysis post-tropical cyclones, highlighting the urgent need for targeted strategies to ensure the continuity of dialysis care during and after such disasters.
A high-resolution numerical simulation of an air–water turbulent upward bubbly flow in a pipe is performed to investigate the turbulence characteristics and bubble interaction with the wall. We consider three bubble equivalent diameters and three total bubble volume fractions. The bulk and bubble Reynolds numbers are $Re_{bulk}= u_{bulk} D/\nu _w = 5300$ and $Re_{bub}= (\langle u_{bub}\rangle - u_{bulk}) d_{eq}/\nu _w = 533\unicode{x2013}1000$, respectively, where $u_{bulk}$ is the water bulk velocity, $\langle u_{bub}\rangle$ is the overall bubble mean velocity, $D$ is the pipe diameter and $\nu _w$ is the water kinematic viscosity. The mean water velocity near the wall significantly increases due to bubble interaction with the wall, and the root-mean-square water velocity fluctuations are proportional to $\bar {\psi }(r)^{0.4}$, where $\bar {\psi } (r)$ is the mean bubble volume fraction. For the cases considered, the bubble-induced turbulence suppresses the shear-induced turbulence and becomes the dominant flow characteristic at all radial locations including near the wall. Rising bubbles near the wall mostly bounce against the wall rather than slide along the wall or hang around the wall without collision. Low-speed streaks observed in the near-wall region in the absence of bubbles nearly disappear due to the bouncing bubbles. These bouncing bubbles generate counter-rotating vortices in their wake, and increase the skin friction by sweeping high-speed water towards the wall. We also suggest an algebraic Reynolds-averaged Navier–Stokes model considering the interaction between shear-induced and bubble-induced turbulence. This model provides accurate predictions for a wide range of liquid bulk Reynolds numbers.
In 1975, the Ugandan state established an Economic Crimes Tribunal to investigate and penalize smuggling, hoarding, overcharging, and other commercial malfeasance. In the coming years, innumerable Ugandans were arrested and charged with contravening the state's economic regulations. Prior observers have seen this as another instance of a capricious state, but in this article, I demonstrate the popular investment in economic regulation. Ugandans demanded better stewardship of money and things because they were aghast at the ungovernable world of commodities. For one thing, the inaccessibility of so-called “essential commodities” — sugar and salt, preeminently — impeded ethical expectations surrounding social reproduction, hospitality, and masculine respectability. More troubling, essential commodities were not completely unavailable; rather, they were available on exclusionary and confusing terms. Relative deprivation was more upsetting than absolute scarcity because it offended a sense of consumptive entitlement. As a result, it was not only the state that accused citizens of economic crimes. There were widespread accusations in which allegation and denunciation circulated among neighbors, families, and bureaucrats in an urgent effort to discipline commodities and people.
Postcolonial governments often restrict the market alienability of land rights for various policy reasons. One policy aims to treat all citizens equivalently and safeguard vulnerable social communities equally, as an unrestrained land market could allow one affluent social group to buy out one that is less affluent. Another policy is to set a standard that is easy to apply in the same way in every case, as a bright-line rule banning land alienation is simpler to administer than a standard that requires case-by-case considerations. Today, in Ethiopia, such laws face opposition from proponents of a free market economy and private property rights. Thus, international development institutions and influential Ethiopians are spearheading an ambitious reform to Ethiopia’s post-socialist law that bans land alienability, arguing that the law has impeded social and economic progress. This article shows, however, that the legal ban has never prevented land transfers. Many people have utilized legal constructs such as gifts, bequests, loans, and leases to sell their land. Such transfers have circumvented the ban amidst aggressive land expropriation by the state and other agents. These intricate local and national dynamics undercut the misleading sense of regularity created by the inalienability law, raising serious questions about the persistent demand by international development institutions to privatize land rights and create land markets through law reform without paying close attention to the lived experiences at the local level.
Many Organization for Economic Co-operation and Development countries invest heavily in labor-market programs to prolong careers. Although active labor-market programs have frequently been evaluated, less is known about passive programs supporting unemployed seniors financially. We focus on the latter by investigating the hiring opportunities of candidates who partake in a regime that ensures dismissed seniors a company supplement alongside regular unemployment benefits. Therefore, we conduct a scenario experiment in which genuine recruiters evaluate fictitious candidates who have spent varying durations unemployed in regimes with and without the company supplement. Because recruiters evaluate candidates' hireability and productivity perceptions, we can identify underlying mechanisms. Overall, we find no evidence of employer-side stigma hindering the re-employment of seniors unemployed in the program. Conversely, longer-term unemployed even benefit from this regime because it mitigates regular stigmatization of long-term unemployment, especially for men. Specifically, recruiters judge them more mildly – particularly regarding flexibility – when they receive the supplement and still apply.
One of the most recognizable cases of preimplantation genetic diagnosis (PGD) is X-linked diseases. Diagnosis of fetal sex is essential for couples who are known to be at risk of some X-linked disorders. The objective of this study was to discriminate between female (XX) and male (XY) embryos by detecting sex chromosomes-specific sequences in spent culture medium and comparing these results to PGD/CGH array results. It may open new window for the development of a non-invasive PGD method. 120 Embryo’s spent media from Day 3 and Day 5 embryos were collected. Modified phenol-chloroform solution was used for DNA extraction from spent media. Sex determination was performed using SRY, TSPY and AMELOGENIN evaluation through quantitative polymerase chain reaction (q-PCR) method. IBM SPSS and MedCalc were used for statistical analyses to compare sex determination of embryos by spent medium with PGD/CGH array results. Culture time was demonstrated to increase the DNA amount among day 5 embryos culture medium samples. Non-invasive PGD by means of spent culture medium gave a sensitivity, specificity, positive predictive value and negative predictive value of 100% for sex determination. Results of sex determination using spent medium by q-PCR were consistent with the results of PGD/CGH array. Improvements in cell-free DNA extraction and PCR amplification procedures provide us an effective method to perform a PGD test without biopsy in the future, especially about X-linked diseases.
Federal law prohibits deceiving the public by falsely marking an item as patented. The “false marking” prohibition has been enforced primarily by private lawsuits on behalf of the United States, with the party plaintiff and the government splitting the penalty. When a court decision dramatically increased the potential recovery for false marking claims, lawyers pounced immediately, filing more cases per week than had previously been filed in years. Indeed, many lawyers who did not previously work on patent cases joined the fray. Within two years, Congress eliminated this type of false marking suit and terminated all pending cases. Using empirical data, interviews with lawyers, legislative history, litigation documents, and news sources, this article tells the instructive history of false marking litigation. This history shows that the supply of private enforcement—lawsuits by private parties to enforce laws in the public interest—is sensitive to market forces. It also shows that, even when concentrated interests encourage Congress to cut back on private enforcement, Congress does not move as quickly as the bar. This matters because once Congress authorizes private enforcement, the maintenance of that system depends on judges and lawyers interpreting private enforcement statutes.
Lower limb rehabilitation robots based on linkage-based mechanisms have recently drawn significant attention in the field due to their numerous advantages. The control of previously proposed linkage-based gait rehabilitation robotic orthoses has been achieved using constant speed control without consideration for the interaction forces. However, such an approach can be harmful to people with stroke since the level of disability varies among individuals, and it may cause potential injuries when excessive force is applied by the robot. To overcome this limitation and improve the rehabilitation process, it is necessary to recognize the force exerted by the person during walking and adjust the robot’s assistive torque accordingly, to provide synchronized motion. Thus, in this work, a human-cooperative approach based on a stiffness control strategy for the six-bar linkage-based gait rehabilitation robot is presented. The proposed methodology can serve as a solid foundation for developing a human-cooperative approach for linkage-based lower limb rehabilitation robotic orthoses. The control was validated and tested with eight healthy human subjects. As a result, customized robotic assistance with this mechanism can be provided during training to meet the individual needs of stroke patients, which can lead to increased engagement and contribution, thus improving treatment outcomes.
Hydrogen is playing an increasingly important role in China's energy and climate policy, with significant implications for the development of a global hydrogen industry. However, China's approach to the regulation of hydrogen, and, in particular, the role of local authorities in promoting hydrogen refuelling stations and fuel cell vehicles, has so far received limited scholarly attention. This article aims to contribute to the literature on hydrogen regulation and to the transnational environmental law scholarship on decentralization by examining how China promotes hydrogen at the national and local levels. The case of China shows how, in jurisdictions with a sufficient degree of decentralization, local initiatives can play a key role in driving the development of hydrogen. By testing different approaches to hydrogen regulation, local experimentation helps to manage the uncertainties associated with this new energy source. At the same time, China's experience confirms the ‘environmental federalism’ theory on the importance of regulatory harmonization to reduce transaction costs and local protectionism. As the Chinese government develops its national regulatory approach on hydrogen, it has the opportunity to take into account both local and international experience and engage with other major economies in an effort to promote an internationally harmonized regulatory landscape.
The number of test translations and adaptations has risen exponentially over the last two decades, and these processes are now becoming a common practice. The International Test Commission (ITC) Guidelines for Translating and Adapting Tests (Second Edition, 2017) offer principles and practices to ensure the quality of translated and adapted tests. However, they are not specific to the cognitive processes examined with clinical neuropsychological measures. The aim of this publication is to provide a specialized set of recommendations for guiding neuropsychological test translation and adaptation procedures.
Methods:
The International Neuropsychological Society’s Cultural Neuropsychology Special Interest Group established a working group tasked with extending the ITC guidelines to offer specialized recommendations for translating/adapting neuropsychological tests. The neuropsychological application of the ITC guidelines was formulated by authors representing over ten nations, drawing upon literature concerning neuropsychological test translation, adaptation, and development, as well as their own expertise and consulting colleagues experienced in this field.
Results:
A summary of neuropsychological-specific commentary regarding the ITC test translation and adaptation guidelines is presented. Additionally, examples of applying these recommendations across a broad range of criteria are provided to aid test developers in attaining valid and reliable outcomes.
Conclusions:
Establishing specific neuropsychological test translation and adaptation guidelines is critical to ensure that such processes produce reliable and valid psychometric measures. Given the rapid global growth experienced in neuropsychology over the last two decades, the recommendations may assist researchers and practitioners in carrying out such endeavors.
CO2 release rates from soils via soil respiration play an important role in the carbon budget of terrestrial ecosystems. Though the roles of soil temperature and moisture on soil respiration are well recognised, less is known about how their effects vary across different land-cover types. This study looked at the interactive effects of land-cover change and microclimate on temporal patterns of soil respiration in a montane forest-grassland-plantation mosaic in a highly diverse but climatically sensitive ecosystem in the tropical Western Ghats of India. Across all vegetation types, soil respiration rates were highest during south-west monsoon (June–October), when root growth, litter decomposition and microbial activity are relatively high and were lowest during the summer. Among vegetation types, soil respiration rates were higher in grasslands compared to non-native pine plantations, whereas that of forest and invasive wattle (Acacia mearnsii) plantations were intermediate between grasslands and pine plantations. The decline in respiration rates following conversion from grasslands to pine plantations could be due to relatively lower microbial activity, soil temperatures and, subsequently, slower litter decomposition. In addition, the sensitivity of soil respiration to changes in temperature and moisture differed between different vegetation types. Across all vegetation types, respiration was largely insensitive to changes in soil temperature when moisture levels were low. However, when soil moisture levels were high, respiration increased with temperature in grassland and wattle patches, decreased in the case of pine plantations and remained largely unchanged in shola forests. Our results suggest that changes in aboveground vegetation type can significantly affect soil C cycling even in the absence of any underlying differences in soil type.
