What's a Weed? Knowledge, Attitude and Behaviour of Park Visitors about Weeds.

ABSTRACT: Weeds are a major threat to biodiversity globally degrading natural areas of high conservation value. But what are our attitudes about weeds and their management including weeds in national parks? Do we know what a weed is? Do we consider weeds a problem? Do we support their management? Are we unintentionally spreading weeds in parks? To answer these questions, we surveyed visitors entering a large popular national park near the city of Brisbane, Australia. Park visitors were knowledgeable about weeds; with >75% correctly defining weeds as 'plants that grow where they are not wanted'. About 10% of the visitors, however, provided their own sophisticated definitions. This capacity to define weeds did not vary with people's age, sex or level of education. We constructed a scale measuring visitors' overall concern about weeds in parks using the responses to ten Likert scale statements. Over 85% of visitors were concerned about weeds with older visitors, hikers, and those who could correctly define weeds more concerned than their counterparts. The majority think visitors unintentionally introduce seeds into parks, with many (63%) having found seeds on their own clothing. However, over a third disposed of these seeds in ways that could facilitate weed spread. Therefore, although most visitors were knowledgeable and concerned about weeds, and support their control, there is a clear need for more effective communication regarding the risk of visitors unintentionally dispersing weed seeds in parks.

Project description:BackgroundCoronavirus disease 19 (COVID-19) is currently a global health threat and public health emergency of international concern. Africa is the last continent to be hit by this pandemic and the population is still prone to misconceptions and may not take it seriously. In developing countries including Ethiopia, where trained human resources and equipment for the treatment of COVID-19 are scarce, working on prevention of the viral spread should be a priority as a feasible intervention strategy. The aim of this study was to determine the level of knowledge, attitude, practice (KAP) towards COVID-19 and its prevalence among hospital visitors.MethodsHealth institution based cross sectional study was conducted among 513 hospital visitors who are recruited by using simple random sampling technique at Ataye district hospital, Northeast Ethiopia from June 3, 2020 to August 10, 2020. A pre-tested structured questionnaire was used to obtain information related to socio-demographic characteristics, knowledge (11 questions), attitude (9 questions) and practice (9 questions). Oro-pharyngeal specimen was collected by trained healthcare provider and processed in a molecular laboratory. After extraction of viral nucleic acid, the Real-time fluorescent polymerase chain reaction (RT-PCR) kit was used for detecting novel coronavirus (2019-nCoV). Data was analyzed using bi-variable and multivariable logistic regression model with 95% CI (confidence interval). From the bi-variable analysis, variables having a P-value <0.25 were retained into multivariable analysis. From the multivariable analysis, variables with a P-value <0.05 was declared as associated factors.ResultsMajority (72.9%) of the study participants were male; and most were urban dwellers. From the total study participants, 17 (3.3%) were found to be infected with the virus. The magnitude of low-level of knowledge was 4.9%; and of the analyzed risk factors, female gender, age (category less than 16 years and category between 16 and 65 years), and usual alcohol drinking habit had statistically significant association with low level knowledge. The proportion of study participants who had low level of practice was 75/513 (14.62%). Family size, age category between 16 and 65 years, and low-level knowledge were associated with low-level practice.ConclusionLimited number of study participants had high-level knowledge and practice towards COVID-19; while majority of the study candidates demonstrated moderate level of knowledge and practice. Good knowledge, positive attitude and good practice can be a guarantee for the prevention and control of COVID-19. Hence, various measurements to combat the pandemic should be taken by different stakeholders including the community members, religious leader, health professionals and others.

Project description:BackgroundCoronavirus disease 2019 (COVID-19) is currently the critical health problem of the globe, including Ethiopia. Visitors of healthcare facilities are the high-risk groups due to the presence of suspected and confirmed cases of COVID-19 in the healthcare setting. Increasing the knowledge, attitude, and practices towards COVID-19 prevention among hospital visitors are very important to prevent transmissions of the pandemic despite the lack of evidence remains a challenge in Ethiopia. Therefore, this study was designed to investigate the status of knowledge, attitude, and preventive practice towards COVID-19 and associated factors among hospital visitors in South Gondar Zone Hospitals, Northwest Ethiopia.MethodsA facility-based cross-sectional study design was employed during August 1 to 30, 2020 from randomly selected 404 adult hospital visitors in South Gondar Zone Hospitals, Northwest Ethiopia. The data was collected using interviewer-administered questionnaire. The outcome of this study was good or poor knowledge, positive or negative attitude and good or poor preventive practice towards COVID-19. Three different binary logistic regression models with 95% CI (Confidence interval) was used for data analysis. For each mode, bivariable analysis (crude odds ratio [COR]) and multivariable analysis (adjusted odds ratio [AOR]) was used during data analysis. From the bivariable analysis, variables with a p-value <0.25 were retained into the multivariable logistic regression analysis. From the multivariable logistic regression analysis, variables with a significance level of p-value <0.05 were taken as factors independently associated with knowledge, attitude and preventive practices towards COVID-19.Main findingsAbout 69.3% of the respondents had good knowledge, 62.6% had a positive attitude, and 49.3% had good preventive practice towards the prevention of COVID-19. We found that factors significantly associated with good knowledge about COVID-19 were educational status who can read and write (AOR = 2.78; 95%CI: 1.18-6.56) and college and above (AOR = 6.15; 95%CI: 2.18-17.40), and use of social media (AOR = 2.96; 95%CI: 1.46-6.01). Furthermore, factors significantly associated with a positive attitude towards COVID-19 includes the presence of chronic illnesses (AOR = 5.00; 95%CI; 1.71-14.67), training on COVID-19 (AOR = 3.91; 95%CI: 1.96-7.70), and peer/family as a source of information (AOR = 2.45; 95%CI: 1.06-5.63). Being a student (AOR = 7.70; 95%CI: 1.15-15.86) and participants who had a good knowledge on COVID-19 (AOR = 4.49; 95%CI: 2.41-8.39) were factors significantly associated with good practice towards COVID-19.ConclusionWe found that knowledge, attitude, and preventive practices towards prevention of COVID-19 among adult hospital visitors were low. Therefore, we recommended that different intervention strategies for knowledge, attitude and preventive practices are urgently needed to control the transmission of COVID-19 among adult hospital visitors. Health education of those who could not read and write about COVID-19 knowledge issues and advocating use of social media that transmit messages about COVID-19 are highly encouraged to increase the good knowledge status of adult hospital visitors. Furthermore, providing training about COVID-19 prevention methods and using various sources of information about COVID-19 will help for improving positive attitude towards COVID-19 prevention, whereas for increasing the status of good preventive practices towards COVID-19, improving the good knowledge about COVID-19 of adult hospital visitors are essential.

Project description:Purpose: This study is designed to identify genes and processes that are differentially regulated in corn when it is grown with or without weeds through the entire critical weed free period (to V8) or when weeds were removed early in the critical weed free period (at V4) and the plants were allowed to recover until V8. Methods: Corn was grown as described above in field plots near Brookings SD in 2007 and 2008 and RNA was extracted from the top-most leaf tips from four plants per treatment plot. Unidirectional cDNA illumina sequencing libraries were constructed for each sample (pooled leaf tips from the given plot), and were sequenced (some samples were paired end sequenced and some were single end sequenced - all 100 bases for PE and SE reads), quality trimmed, and analyzed using the Tuxedo suite of programs for SE reads of the forward read libraries for each sample. Results: We identified a small number of genes that were differentially expressed in both years. More importantly, gene set enrichment analysis of the data determined that weeds, when present through the critical weed free period impacted phytochrome signaling, defense responses, photosynthetic processes, oxidative stress responses, and various hormone signaling processes. When weeds were removed at V4 and the plants allowed to recover until V8, the weeds still imprinted impacts on phytochrome signaling, oxidative stress, and defense responses. Thus, it appears that weeds presence through the early portion of the critical weed free period, even after removal, induced processes that reduce corn growth and yield that lasted at least through V8. Conclusions: This study represents the first investigation of the impact of the lasting effects of weeds during the early critical weed free period on the transcriptome of corn, and provides additional data on the impact of weeds through the critical weed free period that augments and confirms much of what was observed in similar microarray studies.

Project description:Urban park managers are tasked with maintaining ecological function and quality of parks while also meeting visitor preferences. The purpose of this study was to better understand how managers currently manage vegetation in parks of Portland, Oregon. Twenty-one urban park manager interviews were completed regarding 15 parks, which included natural-passive use, recreational-active use, and multi-use park types. Responses were coded for themes and patterns of meaning. Mixed methods were used to evaluate the urban park manager interview data in the context of visitor interview and plant community composition data collected at the same parks. Nonmetric multidimensional scaling ordinations were used to identify urban park manager and visitor perspectives correlated with different park types and their vegetation. Across park types, managers discussed maintenance as a favorite aspect of plant management, while ecosystem management was often described by managers of natural-passive use parks. Some managers indicated that they would make no changes to plant management, but the majority provided detailed recommendations such as enhancing maintenance, increasing staffing, adding plants, updating infrastructure, and improving plant species selection. There are opportunities to better meet the preferences of both managers and visitors by continuing to maintain large trees and trail/path vegetation for accessibility, removing invasive/harmful plants, and improving plant selection to include those that are heartier, more colorful, produce flowers, and are disease resistant, climate adapted, and provide habitat for a variety of species. While urban park managers discussed how they incorporated visitor preferences and accessibility in plant management, they also described limitations such as funding, staff resources, and undesirable visitor behaviors. Increased communication and collaboration among governmental agencies, non-profit organizations, and community members, as well as continued investment in park management and interdisciplinary mixed methods research have the potential to enhance the many ecological and social benefits of urban parks.
