Increasingly, public discourse occurs on social media including about national parks, but how much of it is relevant to park management and what topics/events cause debate? Using a case study approach, we conducted a content and sentiment analysis of tweets about seven South African national parks (Table Mountain, Karoo, Addo Elephant, Pilanesberg, West Coast, Tsitsikamma and Golden Gate Highlands) posted over 14 months on Twitter to assess what topics were discussed for which parks, by whom, when, what emotions were expressed and how such information could be useful for management. Most of the discourse (70% of 10,292 tweets) related to management, including tweets about biodiversity (34%), tourism (27%), natural attractions (17%) as well as crime and safety (10%). Most Tweeters were South African (60%) with other Tweeters from other countries in Africa (4%), the USA (12%) or UK (7%). Although the 2% of accounts from news and conservation organisations had massive followings, most tweets were from individuals, were mainly positive and included emotions such as anticipation and trust. Peaks in tweets often related to specific events in the parks reported in the news. Our study revealed that despite issues with Twitter, such as geographic bias, shortcomings with search terms and short texts, park authorities could consider monitoring Twitter to better understand the interests and opinions of local and international communities. Managers could also use Twitter to monitor reactions to specific events in parks, disseminating information to stakeholders and responding to contentious issues.Invasive species and their establishment in new areas have significant impacts on the ecological, economic, and social well-being of our planet. Wild pigs (Sus scrofa) are one of the world's most formidable invasive species, particularly in the United States. They cause significant damage to agriculture and ecosystems, and can transmit diseases to livestock, wildlife, and people. There is an inherent social dimension to the issue of wild pigs due in part to the fact that people hunt them. Hunting contributes to both the control and spread of this species. The objectives of this study were to 1) determine hunters' overall tolerance for wild pigs; and 2) identify what factors predict hunters' tolerance. Results obtained from a survey of Texas hunters in 2019 indicated that 83% of hunters had a low level of tolerance for wild pigs, with approximately 63% preferring to see the population reduced and 20% preferring to see the population completely removed. Fourteen percent preferred that wild pig numbers remain the same, and 2% preferred to see numbers increase. Results from regression analysis indicated that approximately 53% of the variance in tolerance for wild pigs was explained by motivations and preferences for hunting wild pigs, level of concern for wild pig damage, and overall attitudes toward wild pigs. Results of this research are useful in expanding current knowledge about human tolerance for wildlife, including those species that are non-native and invasive, and in identifying important factors affecting how hunters perceive and interact with wild pigs. Study findings are also helpful in informing the development of effective and socially acceptable management plans for wild pigs, as well as communication efforts aimed at influencing hunters' attitudes and behaviors in the wild pig management context.This study presents the analysis of airborne gamma-ray spectrometry and aeromagnetic data to delineate the distribution of the radioactive elements and determine their anomalous zones, subsurface structures controlled mineralized zones, and 3D magnetic inversion to give a full view of basement relief. According to statistical treatment of airborne gamma-ray spectrometry measurements, the highest values of potassium and equivalent thorium associated with Nakhiel Formation are 3.2% and 12.8 ppm respectively. Meanwhile, the equivalent uranium associated with phosphate beds attains 19.1 ppm. The spatial distribution of the relatively high concentrations of eU, eU/K and eU/eTh are recorded in adjacent areas in Upper Cretaceous deposits as > 12, 25 ppm and 5 ppm for eU, eU/K and eU/eTh, respectively. According to field measurements, the highest values of eU associated with phosphate beds and black Shale are 117 ppm and 20 ppm respectively. Meanwhile, the highest value of potassium associated with Quaternary sediments is 2.9%. Moreover, the highest value of eTh associated with Taref Formation is 16.2 ppm. The geochemical studies of collected samples from the anomalous zones showed the presence of secondary uranium in addition to rare earth elements. Meanwhile, the black shale trace elements are measured and showed high concentrations of tungsten. The magnetic data analysis is performed using tilt derivative and 3D magnetic modeling methods. Most of the deduced structures are trending in NW-SE, and NE-SW directions. The depths to the basement rocks are ranged from 0.475 km to 1.07 km below the ground surface.Gadani shipbreaking area, Pakistan, is the world's third largest shipbreaking unit. However, to date, only a few studies on the environmental impacts of the industry, including mercury (Hg) pollution, have been conducted. To address this, concentrations of total Hg (HgT) and methylmercury (MeHg) were measured in surface sediments collected from the Gadani shipbreaking area as well as a local reference area. The highest concentrations of HgT and MeHg (median ± interquartile range) were detected in samples from the beach at the yard zone (HgT 270 ± 230 μg kg-1, MeHg 0.65 ± 0.69 μg kg-1), followed by sediment samples from the inter/sub-tidal zone where ships are dismantled (HgT 20 ± 5.8 μg kg-1, MeHg 0.043 ± 0.016 μg kg-1). These concentrations were on average 4-50 and 3-30 times greater than the concentrations of HgT and MeHg, respectively, observed in the reference area. CAPSULE Elevated concentrations of total and methylated mercury observed in the Gadani Shipbreaking area sediments.

There is insufficient evidence of the association between oophorectomy and depression.

A nationwide medical records database of South Korea was used to investigate incidence rate ratios (IRRs) of major depressive disorder before and after oophorectomy (n=36,284) using a self-controlled case series design. Outcomes before and after hysterectomy (n=25,415) were identified to compare with those around oophorectomy.

In all oophorectomy and hysterectomy groups, the risk of depression was increased before and after surgery, peaking immediately before or after the operation, with no significant difference in the pattern of the results according to type of surgery. Sunitinib mw In the bilateral oophorectomy group, the IRR was increased between 2-3 months before the surgery, peaking immediately before surgery at 1.39 (95% CI 1.30-1.49, p < .0001), and remained heightened for one-year postexposure. Subgroup analyses performed according to ovarian cancer, age group, and hormone replacement therapy produced results similar to those of the main outcome.
