The impact of flooding on aquatic ecosystem services

Flooding is a major disturbance that impacts aquatic ecosystems and the ecosystem services that they provide. Predicted increases in global flood risk due to land use change and water cycle intensification will likely only increase the frequency and severity of these impacts. Extreme flooding events can cause loss of life and significant destruction to property and infrastructure, effects that are easily recognized and frequently reported in the media. However, flooding also has many other effects on people through freshwater aquatic ecosystem services, which often go unrecognized because they are less evident and can be difficult to evaluate. Here, we identify the effects that small magnitude frequently occurring floods (\u3c 10-year recurrence interval) and extreme floods (\u3e 100-year recurrence interval) have on ten aquatic ecosystem services through a systematic literature review. We focused on ecosystem services considered by the Millennium Ecosystem Assessment including: (1) supporting services (primary production, soil formation), (2) regulating services (water regulation, water quality, disease regulation, climate regulation), (3) provisioning services (drinking water, food supply), and (4) cultural services (aesthetic value, recreation and tourism). The literature search resulted in 117 studies and each of the ten ecosystem services was represented by an average of 12 ± 4 studies. Extreme floods resulted in losses in almost every ecosystem service considered in this study. However, small floods had neutral or positive effects on half of the ecosystem services we considered. For example, small floods led to increases in primary production, water regulation, and recreation and tourism. Decision-making that preserves small floods while reducing the impacts of extreme floods can increase ecosystem service provision and minimize losses

From Servitude to Freedom: Gender, Labor, and Domestic Relations

In the sugar parishes of Louisiana, enslaved people endured high mortality rates and declining populations at the height of the harsh slave regime in the mid-twentieth century. This resulted from regional disease, brutal working conditions, and a skewed sex ratio where enslaved men consistently outnumbered enslaved women. Following emancipation, freedwomen attempted to rebuild their families and community amid the tumultuous environment that defined the sugar parishes. This thesis utilizes Freedmen\u27s Bureau records, American Missionary Association correspondence, census data, and local newspapers to argue that freedwomen sought to gain control over their labor, bodies, relationships, and children in the postbellum era as they were legally free from slavery\u27s constraints. By building upon both Richard Follett\u27s and John Rodrigue\u27s studies of Louisiana\u27s sugar parishes, this thesis places African American women\u27s experiences at the forefront of the region\u27s historiography, where women have been noticeably absent. Through an analysis of labor complaints and domestic disputes filed by freedwomen in the 1860s, this study illustrates that freedwomen were active participants in the transition from slavery to freedom in Louisiana\u27s sugar country

Public Responsiveness to Victim\u27s Recommendations in Their Sentencing Decisions: Role of Victim\u27s Race, Victim Impact Statement and Judge\u27s Instructions

A total of 191 participants completed the 2 (Race of victim: African American, Caucasian) x 2 (Content of Victim Impact Statement (VIS): Sentence Recommendation Only, Both Sentence Recommendation and Harm Statement) x 2 (Jury Guidelines for VIS: No guidance, Explicit instructions to weigh the harm statement with other aggravating and mitigating factors) between subjects factorial design study. The study assessed the relationship between the victim\u27s race (African-American or Caucasian), the content of victim impact statements, and the judge\u27s guidelines/instructions for interpreting/using the Victim Impact Statement (VIS) in the sentencing phase of a defendant\u27s trial for burglary and aggravated battery. The results revealed race of the victim and judge\u27s instructions had no impact on sentencing, or on the goals of sentencing as hypothesized. However, type of VIS was found to have significant effects on sentencing, goals of sentencing, as well as on the participants\u27 perceptions of the victim. Finally, limitations and directions for future research are discussed

Corals of the genus Porites are a locally abundant component of the epibiont community on mangrove prop roots at Calabash Caye, Turneffe Atoll, Belize

Mangroves are generally regarded as inhospitable for corals, but recent reports suggest they provide ecological refuge for some species. We surveyed diverse mangrove habitats on Turneffe Atoll, Belize, documenting 127 colonies of Porites divaricata (Thin Finger Coral) along 1858 m of mangrove prop roots at Calabash Caye and a much more diverse coral assemblage at Crooked Creek. At Calabash, corals were highly clumped, and varied widely in size and morphology, including large well-arborized colonies, encrusting forms with few branches, and new recruits with no branches, suggesting an age-structuredpopulation exhibiting extensive morphological plasticity. The data described here contributeto an emerging picture of mangroves as potentially critical habitat for many Caribbeancoral species.Accepted manuscrip

Test Characteristics of Urinary Lipoarabinomannan and Predictors of Mortality among Hospitalized HIV-Infected Tuberculosis Suspects in Tanzania.

Tuberculosis is the most common cause of death among patients with HIV infection living in tuberculosis endemic countries, but many cases are not diagnosed pre-mortem. We assessed the test characteristics of urinary lipoarabinomannan (LAM) and predictors of mortality among HIV-associated tuberculosis suspects in Tanzania. We prospectively enrolled hospitalized HIV-infected patients in Dar es Salaam, with ≥2 weeks of cough or fever, or weight loss. Subjects gave 2 mLs of urine to test for LAM using a commercially available ELISA, ≥2 sputum specimens for concentrated AFB smear and solid media culture, and 40 mLs of blood for culture. Among 212 evaluable subjects, 143 (68%) were female; mean age was 36 years; and the median CD4 count 86 cells/mm(3). 69 subjects (33%) had culture confirmation of tuberculosis and 65 (31%) were LAM positive. For 69 cases of sputum or blood culture-confirmed tuberculosis, LAM sensitivity was 65% and specificity 86% compared to 36% and 98% for sputum smear. LAM test characteristics were not different in patients with bacteremia but showed higher sensitivity and lower specificity with decreasing CD4 cell count. Two month mortality was 64 (53%) of 121 with outcomes available. In multivariate analysis there was significant association of mortality with absence of anti-retroviral therapy (p = 0.004) and a trend toward association with a positive urine LAM (p = 0.16). Among culture-negative patients mortality was 9 (75%) of 12 in LAM positive patients and 27 (38%) of 71 in LAM negative patients (p = 0.02). Urine LAM is more sensitive than sputum smear and has utility for the rapid diagnosis of culture-confirmed tuberculosis in this high-risk population. Mortality data raise the possibility that urine LAM may also be a marker for culture-negative tuberculosis

Workplace Safety Concerns among Co-workers of Responder Returning from Ebola-Affected Country

We surveyed public health co-workers regarding attitudes toward a physician who returned to New Hampshire after volunteering in the West African Ebola outbreak. An unexpectedly large (18.0%) proportion of staff expressed discomfort with the Ebola responder returning to work. Employers should take proactive steps to address employee fears and concerns

World Peace and Gender Equality: Addressing UN Security Council Resolution 1325’s Weaknesses

The year 2020 marks the twentieth anniversary of the passage of United Nations Security Council Resolution (“UNSCR”) 1325, the most important moment in the United Nations’ efforts to achieve world peace through gender equality. Over the past several decades, the international community has strengthened its focus on gender, including the relationship between gender and international peace and security. National governments and the United Nations have taken historic steps to elevate the role of women in governance and peacebuilding. The passage of UNSCR 1325 in 2000 foreshadowed what many hoped would be a transformational shift in international law and politics. However, the promise of gender equality has gone largely unrealized, despite the uncontroverted connection between treatment of women and the peacefulness of a nation. This Article argues for the first time that to achieve international peace and security through gender equality, the United Nations Security Council should transition its approach from making recommendations and suggestions to issuing mandatory requirements under Chapter VII of the U.N. Charter. If the Security Council and the international community believe gender equality is the best indicator of sustainable peace, then the Security Council could make a finding under Article 39 with respect to ‘a threat to the peace’—States who continue to mistreat women and girls pose a threat to international peace and security. Such a finding would trigger the Security Council’s mandatory authority to direct States to take specific actions. In exercising its mandatory authority, the Security Council should organize, support, and train grassroots organizations and require States to do the same. It should further require States to produce a reviewable National Action Plan, detailing how each State will implement its responsibilities to achieve gender equality. The Security Council should also provide culturally sensitive oversight on domestic laws which may act as a restraint on true gender equality

Enhanced recovery pathways improve early outcomes and reduce length of stay in primary hip and knee arthroplasty: A systematic review of randomized controlled trials

Background: Enhanced Recovery After Surgery (ERAS) protocols represent an evidence-based approach to perioperative care, though evidence from randomized controlled trials in primary hip and knee arthroplasty remains limited. Objective: This systematic review aims to synthesize evidence from randomized controlled trials (RCTs) comparing ERAS protocols with standard care for primary hip and knee arthroplasty. Methods: Four databases were searched following PRISMA guidelines. RCTs comparing ERAS protocols with standard care for primary hip or knee arthroplasty were included. Primary outcome was length of stay (LOS), with secondary outcomes including patient-reported outcomes, functional measures, and complications. Results: Five RCTs (710 patients) met inclusion criteria. ERAS pathways reduced LOS by an average of 4.7 days compared to standard care. Patients in ERAS protocols demonstrated superior early functional recovery, particularly in the first postoperative week, with improved performance in mobility tests and daily activities. Patient-reported outcomes generally favoured ERAS protocols, though measurement heterogeneity limited synthesis. No studies reported increased complications with ERAS implementation. The role of multidisciplinary teams, particularly nurse coordinators, was identified as an important for protocol success. Conclusion: This systematic review of RCTs provides strong evidence that ERAS pathways reduce length of stay following primary hip and knee arthroplasty without compromising patient outcomes or safety. While ERAS protocols were associated with improved early functional recovery, heterogeneity in assessment methods limits definitive conclusions
