Effects of Recreational Camping on the Environmental Values of National Parks in Sri Lanka.

Camping is a popular activity in the contemporary nature-based tourism domain and rapidly gaining momentum as a key recreational activity in Sri Lanka's national parks (NPs). Recreational uses such as camping in natural areas can induce significant and often localised resource impacts that can affect soil, vegetation, wildlife and water, with the severity of such impacts varying according to the intensity of use. Hence, monitoring of the biophysical conditions of campsites has become an important component in the reserve management agenda in many places, especially in developed countries.

One Health, "Disease X" & the challenge of "Unknown" Unknowns.

The emergence of SARS-CoV-2 and its rapid spread globally emphasizes the ever-present threat of emerging and re-emerging infectious diseases. In this review, the pathogen pyramid framework was utilized to identify the "unknown unknowns" associated with the emergence and rapid transmission of novel infectious disease agents. Given that the evolutionary origin of most of the emerging infectious disease agents can be traced to an animal source, we argue the need to integrate the "One Health" approach as a part of surveillance activities.

Research priorities for control of zoonoses in South Africa.

Background: Zoonoses pose major threats to the health of humans, domestic animals and wildlife, as seen in the COVID-19 pandemic. Zoonoses are the commonest source of emerging human infections and inter-species transmission is facilitated by anthropogenic factors such as encroachment and destruction of wilderness areas, wildlife trafficking and climate change. South Africa was selected for a 'One Health' study to identify research priorities for control of zoonoses due to its complex disease burden and an overstretched health system.

Scoping Recreational Disturbance of Shorebirds to Inform the Agenda for Research and Management in Tropical Asia.

In addition to scoping the impacts of the four most reported sources of recreational disturbance on shorebirds, this study also advances the concept of Tropical Asia (TA) to collectively describe tourist destinations in the ecologically and geopolitically diverse part of the planet that incorporates the tourism megaregion of South and Southeast Asia. At a time of growing global concern about the rapid decline of shorebird populations, many governments in TA are embracing and capitalising on the exponential growth in demand for coastal recreation and tourism across the region. This political response is partly driven by efforts to deliver economic development, aligned to the United Nations Sustainable Development Goals, in order to secure the livelihoods of people living in less developed coastal areas.

COVID-19 in Africa: care and protection for frontline healthcare workers.

Medical staff caring for COVID-19 patients face mental stress, physical exhaustion, separation from families, stigma, and the pain of losing patients and colleagues. Many of them have acquired SARS-CoV-2 and some have died. In Africa, where the pandemic is escalating, there are major gaps in response capacity, especially in human resources and protective equipment.

Collision metastasis of prostatic adenocarcinoma and urothelial carcinoma of the bladder.

The incidence of concomitant prostate adenocarcinoma found in patients with muscle-invasive bladder carcinoma is not uncommon, reaching up to 21%-28%. However, the presence of collision metastasis involving prostate cancer and bladder cancer within the same lymph node is exceedingly rare, with only 5 cases reported to date in the literature. We report a case of collision metastasis of prostate adenocarcinoma and urothelial carcinoma of the bladder in a 73-year-old man who underwent cystoprostatectomy with bilateral pelvic lymph node dissection for high-grade muscle-invasive urothelial carcinoma.

Characterization and outcomes of local treatment for primary bladder lymphoma: A population-based cohort analysis.

Introduction: Primary bladder lymphoma (PBL) is rare, representing 0.2% of extranodal lymphoma and less than 1% of all tumors originating in the bladder. Since the initial description of the disease, low-grade mucosa-associated lymphoid tissue (MALT) lymphoma has been reported as the most common subtype while high-grade disease was thought to represent only 20% of the reported cases.

Data from a survey to determine visitor attitudes and knowledge about the provisioning of wild dolphins at a marine tourism destination.

In the Austral summer of 2014-2015 we surveyed visitors at the popular marine tourism destination of Koombana Bay, Bunbury, Western Australia to investigate resident and visitor attitudes towards the provisioning of the wild dolphins and their knowledge about the legal, social and environmental repercussions arising from the unregulated provisioning of the dolphins. We report the data collected in our survey along with our preliminary statistical analyses and the survey instrument we utilized to collect the data.

Population Dynamics of Owned, Free-Roaming Dogs: Implications for Rabies Control.

Background: Rabies is a serious yet neglected public health threat in resource-limited communities in Africa, where the virus is maintained in populations of owned, free-roaming domestic dogs. Rabies elimination can be achieved through the mass vaccination of dogs, but maintaining the critical threshold of vaccination coverage for herd immunity in these populations is hampered by their rapid turnover. Knowledge of the population dynamics of free-roaming dog populations can inform effective planning and implementation of mass dog vaccination campaigns to control rabies.

Primary bladder lymphoma, diffuse large B-cell type: Case report and literature review of 26 cases.

Primary lymphoma of the urinary bladder is exceedingly rare, representing 0.2% of all extranodal non-Hodgkin's lymphoma. Although Matsuno et al.

Upper extremity muscle volumes and functional strength after resistance training in older adults.

Aging leads to a decline in strength and an associated loss of independence. The authors examined changes in muscle volume, maximum isometric joint moment, functional strength, and 1-repetition maximum (1RM) after resistance training (RT) in the upper extremity of older adults. They evaluated isometric joint moment and muscle volume as predictors of functional strength.

An unexpected co-crystal with a variable degree of order: 1:1 rac-1,2-cyclohexanediol/triphenylphosphine oxide.

A 1:1 co-crystal of rac-trans-1,2-C(6)H(10)(OH)(2) and (C(6)H(5))(3)PO has been found that is unusual because there are no strong interactions between the two kinds of molecules, which are segregated into layers. Furthermore, neither pure rac-1,2-cyclohexanediol (CHD) nor pure triphenylphosphine oxide (TPPO) has any obvious packing problem that would make the formation of inclusion complexes likely. The TPPO layers are very much like those found in two of the four known polymorphs of pure TPPO.

The English Lexicon Project.

The English Lexicon Project is a multiuniversity effort to provide a standardized behavioral and descriptive data set for 40,481 words and 40,481 nonwords. It is available via the Internet at elexicon.wustl.

Solid-state compounds of stereoisomers: cis and trans isomers of 1,2-cyclohexanediol and 2,3-tetralindiol.

The phases of 1,2,3,4-tetrahydro-2,3-naphthalenediol (or 2,3-tetralindiol) and of 1,2-cyclohexanediol have been investigated. The structure of a very stable 1:1 compound (or co-crystal) of the cis and trans isomers of 2,3-tetralindiol, the existence of which has been known for nearly a century, has finally been determined. No evidence of any analogous compound between the cis and trans isomers of 1,2-cyclohexanediol has been found.

Developmental, crosslinguistic perspectives on visual word recognition.

In this paper, we argue that a complete understanding of language processing, in this case word-recognition processes, requires consideration both of multiple languages and of developmental processes. To illustrate these goals, we will summarize a 10-year research program exploring word-recognition processes in Korean adults and children. We describe the particular issue to which this research is directed (the relationship between print and the sound system of the language), and describe the characteristics of the Korean writing system that are relevant to this issue.

The influence of phonological neighborhood on visual word perception.

In the research reported here, we investigated the influence of phonological neighborhood density on the processing of words in the visual lexical decision task. The results of the first experiment revealed that words with large phonological neighborhoods were verified more rapidly than words with small phonological neighborhoods. In the second experiment, we replicated this effect with a more tightly controlled set of stimuli.

Semantic and phonological influences on the processing of words and pseudohomophones.

In two experiments, we investigated the relationship between semantics and phonology in the lexical decision task. In the first experiment, lexical decisions to words with large semantic neighborhoods were faster than those to words with sparse semantic neighborhoods. Conversely, this effect of semantic neighborhood was reversed for pseudohomophones (e.

Semantic neighborhood effects on the recognition of ambiguous words.

The effect of semantic neighborhood on the processing of ambiguous words was examined in two lexical decision experiments. Semantic neighborhood was defined in terms of semantic set size and network connectivity. In Experiment 1, the variables of semantic set size, network connectivity, and ambiguity were crossed.
