Effects of Flowering Mode and Pollinator Sharing on Reproductive Success in Natural Hybrid of Two Epimedium(Berberidaceae)Species

Mediated by pollenflow,natural hybridization is deemed a crucial factor that propels speciation infloral plants.Despite the fact that the diversity of Epimedium species is concentrated mainly in Southwestern China,the poten-tial impact of interspecific pollination on natural hybridization has yet to be empirically scrutinized.To explore this,we studied theflowering period and the visitors offlowers in three frequently overlapping Epimedium species at Jinchengshan National Forest Park,located in Nanchong,Sichuan Province.Additionally,we performed a ser-ies of pollination experiments to examine breeding systems and hybrid compatibility.Morphologically,Epime-dium pubescens and Epimedium wushanense are clearly distinct and easily recognizable byflower morphology,while the putative hybrid is morphologically intermediate between them.Our observation revealed that E.pub-escens and E.wushanense had 15 days of overlapping anthesis.Both species are self-incompatible and require pol-linator services for successful reproduction.Although their pollinators differ in quantity and species,Lasioglossum sp.(Hymenoptera:Halictidae)visited all three species.Artificial pollination revealed no breeding barriers among the three species,and the resulting hybrid seeds exhibited fertility.The overlapping time offlowering,commonfloral visitors,and compatibility of hybrids may be important factors contributing to successful interspecific pol-lination and speciation for natural hybrid species of E.pubescens and E.wushanense.Consequently,the role of potential interspecific pollination is crucial for hybrid speciation and the evolutionary dynamics of Epimedium species.

A system-integrated approach for the design of tourist areas at the local level under changing conditions:A case study in the Altay Mountains

The existing approaches for the design of tourist areas often lead to limited flexibility in project implementation.To realize a more flexible approach,in this study,we formulated a model for planning and designing tourist areas at the local level.Moreover,specific tools for analyzing tourist areas and ensuring sustainable development under changing conditions were developed.This study was conducted in two tourist regions,Biryuzovaya Katun tourist complex and Belokurikha destination(including Belokurikha City with Belokurikha 2 Gornaya tourist complex and surrounding areas),in the Altay Mountains.We employed the recreation opportunity spectrum and proposed a system-integrated programming approach for the design of tourist areas at the destination and site levels.The key of this approach was the collection and analysis of current spatial data,including the spatial distribution of attractions and visitor flows.We constructed heat maps using video recording and unmanned aerial vehicle(UAV)observation data.Moreover,we analyzed the video stream using an image-analyzing framework You Only Look Once(YOLO)v5 software.The heat map of visitor flows based on video recording data in the Andreevskaya Sloboda museum of Belokurikha 2 Gornaya tourist complex allowed us to highlight the most attractive sites in this area and classify them into one of three types:points of functional concentration,points of transitional concentration,and points of attractions.The heat maps in Biryuzovaya Katun tourist complex,created using UAV observation data,allowed us to determine the spatiotemporal patterns of visitor flows and tourists’preferences throughout the day within four time intervals:09:00-12:00,13:00-14:00,14:00-15:00,and 16:00-18:00(LST).The maximum visitor flow density occurred from 16:00 to 18:00 in the beach area of the artificial lake.A comparison between the visitor-concentrated sites and the current facilities provided insights into the demand for attractions and facilities and the lacking areas.Heat maps are useful in analyzing the land use at the site level,while zoning based on the recreation opportunity spectrum can be used to design tourist areas at the destination level.The proposed methods for analyzing the use of tourist areas contribute to the development of adaptive tourism design.

Segmentation by domestic visitor motivation: Changbai Mountain Biosphere Reserve, China

Protected areas have become important tourism products that promoted as attractions by the tourism industry. Taking the Changbai Mountain Biosphere Reserve in Northeast China as a case, this study addresses visitor needs as a basis for developing a tourism strategy aimed at enhancing tourist opportunities at this reserve. A factor-cluster approach was employed to identify visitor segment profiles based on their visit motivations. Through random sampling, a pencil-and-paper questionnaire in Chinese language was collected from 637 domestic tourists in the study area. A principal components analysis of motivations revealed eight motivational factors, and four distinct groups of tourists – Nature travelers, Cultural landscape tourists, Food & shopping enthusiasts, and Eclectic adventurers – were identified. Understanding the differences in these visitor segments will help the management authority effectively analyze nature reserve attributes and provide alternative activities and services to tourists. Finally, within the dual framework of market segmentation and destination management some management recommendations and marketing implications are suggested.

An analysis of first-time and repeat visitors to Korean national parks from 2007 and 2013

This paper examined visitors to Bukhansan National Park in Korea based on first-time and repeat visitation. Bukhansan National Park is Korea's most heavily visited national park with annual visitation of six million visitors in 2015. Data used in this article were collected on-site in the park in 2007 and 2013 by the Korea National Park Service(KNPS).The study variables included socio-demographics,travel behavior, motivation, and satisfaction with park attributes, services and facilities. Data were analyzed by each study year for first-time and repeat visitors.Results showed significant differences for both firsttime and repeat visitors on several socio-demographic,travel behavior, and motivation variables within each study year. For satisfaction with park attributes,facilities and services, first-time visitors were significantly different from repeat visitors on seven variables for both years. Implications are given regarding programs and services to improve visitor satisfaction and sustain the natural, cultural and historical resources at Bukhansan National Park and other national parks in Korea. Future research suggestions are provided to learn more about visitor characteristics, standards of quality and preferences in the national parks.

Modeling visitor use on high elevation mountain trails: An example from Longs Peak in Rocky Mountain National Park, USA

Increasing use on mountain summits has both social and ecological implications.High numbers of visitors climbing mountain summits can be a safety issue,particularly in areas where terrain or elevation leads to queueing that may cause time delays.Estimating visitor use levels at site specific locations en route to summits is needed to understand the potential benefits and impacts of visitor use in these locations.However,it can be difficult to obtain reliable and robust data to estimate use and develop statistical relationships because of the remote and harsh climates on mountain summits,as well as the financial and personnel requirements involved to collect the data in remote locations.In 2015,data were collected on the higher stretches of the Keyhole Route on Longs Peak in Rocky Mountain National Park,USA(RMNP)to better understand use levels near the summit and to explore potential statistical relationships to trailhead use data that are relatively easy to collect.Strong statistical relationships from robust regression analyses were found between trailhead use counts and daily and hourly use totals on the"Homestretch"which is a final section of the Keyhole Route.Additionally,a strong statistical relationship was found between total daily use and maximum hourly use on the Homestretch.The results suggest that trailhead counts are an accurate and reliable means from which to estimate use levels on upper portions of the Keyhole route.Moreover,this research demonstrates the usefulness of an approach using proxy variables to estimate visitor use along remote peaks where data collection can be difficult.These types of data can elucidate various options and decisions for park management teams who are charged with deciding if and how to manage high use areas.

Violence against health care staff by patient’s visitor in general hospital in Greece: Possible causes and economic crisis

This study examined the types of violence experienced by physicians, nurses and nurse assistants in various departments by patients’ visitors. Few studies have focused on patients’ visitors’ violence against nurses or physicians in general hospitals and various departments in the beginning of economic crisis in Greece. A total of 250 health care staff—physicians, nurses, nurses’ assistants—took part in a questionnaire-based study. A majority of respondents had experienced some forms of violence (verbal, psychological, physical and sexual). The most frequently reported incident was verbal violence followed by psychological violence. Violation of visiting hours and long waiting periods were among the most common causes of violence. Associations were found between workplace violence and demographics and types of wards. Nurses identified economic crisis to be the major cause of violence. The most significant finding is the high rate of workplace violence caused by patients’ visitors due to economic crisis and the fact that we found no statistically significant differences in the prevalence of violence among different health professionals.

Agglomerative Approach for Identification and Elimination of Web Robots from Web Server Logs to Extract Knowledge about Actual Visitors

In this paper we investigate the effectiveness of ensemble-based learners for web robot session identification from web server logs. We also perform multi fold robot session labeling to improve the performance of learner. We conduct a comparative study for various ensemble methods (Bagging, Boosting, and Voting) with simple classifiers in perspective of classification. We also evaluate the effectiveness of these classifiers (both ensemble and simple) on five different data sets of varying session length. Presently the results of web server log analyzers are not very much reliable because the input log files are highly inflated by sessions of automated web traverse software’s, known as web robots. Presence of web robots access traffic entries in web server log repositories imposes a great challenge to extract any actionable and usable knowledge about browsing behavior of actual visitors. So web robots sessions need accurate and fast detection from web server log repositories to extract knowledge about genuine visitors and to produce correct results of log analyzers.

Culturally Sensitive Medical Care and Nursing Support: A Study of the Concerns of Foreign Visitors to Japan

Background: Considering the development of international transportation in modern societies, nursing care needs to be sensitive to the cultures and customs of patients from other countries. The purpose of this study is to determine, from the perspective of culturally sensitive nursing support, the cultural practices that foreigners consider important when they visit a Japanese hospital for check-ups or hospitalization. Methods: A survey was completed by 110 foreign participants at a shrine in Kyoto City. The purpose of the survey was to evaluate the concerns of foreign visitors regarding Japanese medical providers, caused by cultural differences such as customs of daily life. The statistical analyses were performed using descriptive statistics as well as cross-tabulation, chi-square, and Fisher’s exact tests. Results: After grouping participants by continent, the top concerns observed in all groups about visiting a Japanese hospital were accessibility to and cost of medical care. First, as for medical facilities, participants from North and South America (North and South American) and Europe (Europeans) were significantly more concerned than those in Asia (Asians) (P P P P P Conclusion: Nurses need opportunities to learn and understand differences in cultures. If nurses have opportunities to learn cultural differences as well as to experience caring for foreign patients, their competencies in culturally sensitive nursing support will improve over time. It can be said that this is an issue not only in Japan but also in all other countries.

The Spatial Variability and Temporal Dynamics of Soil Properties as Affected by Visitors’ Pressure in an Urban Park

Soil properties and their tempo-spatial heterogeneity, affected by visitors’ pressure, season and soil depth, were studied in an urban park in Tel-Aviv. Soil was sampled twice yearly in wet and dry seasons. In each season soil was sampled from areas exposed to differing levels of visitors’ pressure (VP), and designated “no VP (Control)”, “High VP” and “Low VP”. The soil samples were taken from two depths. For each soil sample, moisture, organic matter and soluble-ion contents, pH, and electrical conductivity were determined. It was found that different properties were differently affected by VP, seasonal dynamics and soil depth: organic matter content, penetration depth and sodium concentration were the most sensitive to VP;Soil moisture did not respond to VP, but sharply reflected seasonal changes;Calcium and organic matter contents were significantly affected by the soil depth. The sensitivity of soil properties to VP increased from March to July, and the upper soil layer was more sensitive to seasonal dynamics and VP than the deeper layer. Some soil properties exhibited “spotty” patterns;others a “frontal” one. Organic matter content was completely controlled by VP at both depths and in both seasons, and could be used as an indicator of soil status in recreation areas. Visitors’ activities included trampling and other anthropogenic factors that enhanced the spatial changes and seasonal dynamics of soil properties. Based on these measurements the intensity of soil degradation and dynamics was evaluated and used to describe the soil status in an urban park.

The Potential of Foodservice Operations at Visitor Attractions in Ghana

The success of a tourist attraction embeds in the provision of foodservice facilities that has the potential to offer the visitor experiences demanded at the sites. In an attempt to explore the relationships between visitor attractions and foodservice in Ghana, this paper provides evidences from an investigation conducted at six selected visitor attractions at various destinations. Due to the paucity of published data on the concept under investigation, this study included two phases： qualitative followed up with a quantitative research. However, the second one, which was based on a survey involving international and domestic visitors （528）, is the main focus of this paper. The information gathered in phase one informed the design for the visitors＇ survey, whose data were analyzed through the Statistical Product and Service Solutions （SPSS）. Findings from the study showed a high demand for foodservices at all attractions. Collaborations among formally trained staff and informal or traditional foodservice outlets to develop local cuisines at visitor attractions offer the potential to positively support the tourism industry in Ghana as well as those of other African countries seeking to develop the tourism sectors of their economies. This paper may also be of interest to the relevant and international bodies such as UNWTO, UNDP, and UNEP who seek to promote the development of sustainable practices.
