This study aims to analyze the effect of variety of selection to web browsing and e- impulse buying for consumer Bukalapak in Kebumen Regency. Variable independent in this study variety of selection, variable dependent e-impulse buying, and variable intervening web browsing. This study confirm two types of web browsing occur: utilitarian browsing and hedonic browsing. Consumer Bukalapak in Kebumen Regency completed a total 100 questionnaires using Google Form. Data analyze was conducted using Path analysis and SPSS 22.0. In a structural model, variety of selection has a possitive effect on utilitarian browsing and hedonic browsing. Additionally, utilitarian browsing has a negative effect on e-impulse buying. In particular, the factor variety of selection haven’t direct effect on e-impulse buying, but have indirect effect to e-impulse buying with mediate hedonic browsing.

Full textAbstract:
Goats browsing in a tropical deciduous forest (TDF) obtain a large proportion of their diet from a large number of plant species. Nevertheless, the goat’s feed resource selection has not been studied in such an ecosystem. This study aimed to determine whether goats browsing in a TDF display active feed resource selection. Two browsing sites were used (A = 2.2 ha and B = 2.6 ha). The effective availability (g) of all plant species available was measured for each site using 10 m × 20 m exclusion quadrants. Three non-pregnant adult goats (34.9 ± 2.4 kg liveweight) with browsing experience were observed using the continuous bite monitoring method to determine their respective dry matter intake. The selection of different plants was determined using the Jacobs’ selection index (JSI). The goats’ dry matter intake per day was 723 and 310.8 g for Sites A and B, respectively. At both browsing sites, the plant with the highest biomass availability was Gymnopodium floribundum (75.5% and 49.3% for Sites A and B, respectively). Nevertheless, the plant species most actively selected by goats were Eragrostis ciliaris at Site A (JSI = 0.99, P < 0.05) and Mimosa bahamensis at Site B (JSI = 0.96, P < 0.05). Some plant species were not consumed at Sites A and B (three and five species, respectively). In conclusion, feed resource selection was not associated with the biomass availability of the plants selected or refused. Goats were able to show active feed resource selection in the TDF, and this could change according to the characteristics of the browsing site.

Full textAbstract:
The two main ways to search for information in electronic document collections are by using free-text retrieval search engines or browsing information that has been organized into predefined organizational structures. However, each of these approaches has limitations. Using word or phrase search, users are faced with a compromise between overly broad searches returning an excessive amount of information or overly narrow searches that may fail to return relevant information. Browsing organizational structures is dependent on the user's knowledge of the structures, and a user may find it difficult to refine searches. This paper introduces a user interface based approach to the browsing of hierarchically organized information entities that avoids these problems by allowing the incremental narrowing down of a set of search results and by pruning the organizational structure after each user selection to show the consequences of the selection. The effect is to present to the user at all times only that part of the organizational structure that will lead to a nonnull selection. The approach is called no zero match (NZM) browsing. The paper presents the computational basis of NZM browsing before describing a trial implementation of the approach and presenting three case studies, which represent common search situations in an engineering context.

Full textAbstract:
Abstract Browsing of seedlings by white-tailed deer (Odocoileus virginianus) can make natural and artificial forest regeneration difficult. Few mathematical models predict deer browsing within and between sites, giving managers only landscape-level characteristics, such as deer population levels and yearly snowfall measurements, to determine where deer-protective measures should be installed. This study described browsing patterns and assessed influence of vegetational characteristics on browsing. Predictive models were developed using overstory and understory measurements, and browsing reconstructions of individual seedlings within eight eastern white pine (Pinus strobus) plantations in northern Minnesota. Results indicated that deer concentrate browsing on terminal leaders in shorter seedlings, shifting to laterals as seedlings approach browsing height limits (140 cm).Damage models were site-specific. The vertical and horizontal distribution of understory vegetation and the presence of alternative food sources influenced the probability of browsing. Future models should incorporate these measures as well as browse selection patterns, landscape-level characteristics,and past deer activity. North. J. Appl. For. 16(2):96-102.

Full textAbstract:
Increased ungulate browsing alters the composition of plant communities and modifies forest ecosystems worldwide. Ungulates alter their diet following changes in availability of plant species; however, we know little about how browse selection and plant community composition change with different stages of deer establishment. Here, we provide insight into this area of study by combining multiple approaches: comparison of the understory plant community, analysis of records of browsing damage, and DNA barcoding of sika deer feces at 22 sites in forests in northern Japan varying in when deer were first established. The coverage of vegetation and number of plant species were only lower at sites where deer were present for more than 20 years, while the difference in plant coverage among deer establishment years varied among plant species. Deer diet differed across establishment years, but was more affected by the site, thereby indicating that food selection by deer could change over several years after deer establishment. Plant life form and plant architecture explained the difference in plant coverage across establishment years, but large variability was observed in deer diet within the two categories. Integrating these results, we categorized 98 plant taxa into six groups that differed in vulnerability to deer browsing (degree of damage and coverage). The different responses to browsing among plant species inferred from this study could be a first step in predicting the short- and long-term responses of forest plant communities to deer browsing.

Full textAbstract:
We investigated the selection criteria of moose, Alces alces (L., 1758), feeding on two willow species, Salix phylicifolia L. and Salix myrsinifolia Salisb., and whether these willows respond chemically. We correlated winter twig browsing with the concentrations of primary and secondary plant compounds in twigs and new leaves. Furthermore, we investigated 12 specific phenolics in twigs of S. phylicifolia. During winter, moose browsed twigs with low concentrations of phenolic compounds. Additionally, we found significant negative correlations between browsing and the concentration of 7 of the 12 specific phenolic compounds in S. phylicifolia. Most importantly, even though ours was a field study and had many potential sources of variation, a multivariate analysis revealed that these specific phenolics predicted 47% of the variation in moose browsing. The two willows reacted in different chemical ways to moose browsing, but both showed signs of defensive response in early spring and compensation growth in summer. Our data demonstrate the importance of plant secondary chemicals for feeding behaviour of moose and underline the importance of working at a species level in studies of plantanimal interactions, especially with the chemically heterogeneous willows.

Full textAbstract:
Given school librarians promote reading and assist students in the self-selection of texts, this case study examines youth information-seeking practices, specifically book selection, within the context of a genrefied fiction collection. It examines how sixth grade students interacted with the collection along with their teachers’ perceptions of the collection’s recent genrefication. Data includes observation and video recording of 16 sixth grade students’ browsing activity during four checkout times, interviews with eight students, and survey responses from eight classroom teachers. Findings include that students used prior knowledge of genre for beginning book selection, preferred browsing with a peer and were more likely to leave with a book when they did, and tended to browse across genres even when coming to the library with a particular genre in mind. Classroom teachers viewed genrefication as a means for supporting students as readers, and appreciated that the library’s organization reinforced their curricular goals around teaching the concept of genre.

Full textAbstract:
Mountain hares (Lepus timidus) in Scandinavia are classified as Near Threatened in the Norwegian and Swedish Redlists. This is due to a possible population decline witnessed during the last decades in Scandinavia. Competition between large herbivores and mountain hares is one of several hypotheses that has been put forward to explain this decline. In a cafeteria trial we investigate the effects of previous moose (Alces alces) winter browsing on the food selection (i.e., biomass consumed, bites per minute and bitediameter) of downy birch (Betula pubescens) and goat willow (Salix caprea) by captive mountain hares. We find that mountain hares do not differentiate among previous browsing levels of downy birch, but have larger bite diameters of goat willow earlier browsed by moose, compared to non-browsed plants. Thus, effects of moose on mountain hare winter food quality seem to be limited. We highlight the need for studies focusing on (1) qualitative effects of moose browsing using wild mountain hares in a natural experimental design, and (2) quantitative effects of moose browsing on available mountain hare forage at a landscape scale during winter.

Ten years ago the working group “Forest and Wildlife” of the Swiss Forestry Society described the situation at the time regarding forest and game in Switzerland. Since then data collection and evaluation methods for assessing browsing damage, but also forest and wildlife management concepts have evolved. A selection of the many activities in this field are presented in this article, namely the cantonal overviews of Cantons Glarus, Schwyz and Berne, the surveys on browsing intensity on indicator plots in Cantons St. Gallen, Glarus, Zurich, Schwyz and in the Bernese Oberland, as well as the Forest and Wildlife Reports and the Silver Fir Action Program of Canton Grisons. Furthermore the results of the Effor2 pilot program “forest and wildlife” and of the studies on the development of natural regeneration and the behaviour of wild ungulates in areas damaged by storm Lothar are presented, together with results from the 3rd National Forest Inventory. The results show: the proportion of forest area in the cantons with intolerable browsing damage seldom exceeds 25%. Browsing problems are more frequent in game protection areas. According to the 3rd National Forest Inventory browsing intensity has increased in Switzerland, but decreased in the Plateau. A diminution of the browsing intensity is also shown by the the surveys on indicator plots in Cantons St. Gallen, Glarus, Zurich, Schwyz and in the Bernese Oberland. In some regions one has succeeded in avoiding a loss of stem numbers due to browsing, even concerning the particularly vulnerable silver fir. This however remains the exception rather than the rule. This is the reason why Canton Grisons has launched the Silver Fir Action Program.

Journal of Animal Science 99, Supplement_3 (October 8, 2021): 79. http://dx.doi.org/10.1093/jas/skab235.143.
Full textAbstract:
Abstract Oak-hickory (Quercus spp. and Carya spp.) recruitment and regeneration are negatively impacted by non-natives species. Goats can provide an initial control of non-native vegetation; however, browsing behavior and preference should be studied before their introduction in the forest. Our objective was to analyze goats’ browsing behavior and preference in an eastern oak-hickory forest. We hypothesized that browsing behavior and preference are dependent on browse biomass composition and grazing duration. This study was conducted in Coshocton, Ohio, and contained two units with nine experimental plots each. Vegetation was surveyed during the summer of 2019 for biomass composition. Cluster analyses were performed using species identity and biomass. Vegetation nutritional analysis including fiber, protein, and sugar was completed. Two stocking rate densities were implemented: high (1,019 goat×day×ha-1) and low (509×goat×day×ha-1). Goats browsed for four or two days for a total of 36 days. Continuous observation was implemented to determine browsing behavior. Forage selectivity was measured using Jacob’s Selectivity Index (JSI). A linear mixed model was calculated using clusters, species, and/or grazing duration (fixed effect), experimental plots (random effect), and JSI (dependent variable). Spicebush (Lindera benzoin), multiflora rose (Rosa multiflora Thunb.), privet (Ligustrum spp.), and oriental bittersweet (Celastrus orbiculatus Thunb.) composed more than 70% of goats’ diet. Species identity, including nutritional components and physical defense mechanisms, was the most important factor in browsing selectivity. Goats preferred spicebush and privet and avoided multiflora irrespective clusters (P 0.001). In the first two days of browsing, goats favored spicebush and privet, avoided multiflora, and had a neutral preference for bittersweet (P-value 0.001). In the last two days, privet was selected and other species had a neutral selection (P 0.001). Goats will target spicebush and privet and avoid multiflora; therefore, an extended browsing period is recommended. Future studies should evaluate the effect of chemical defense mechanisms on browsing.

Full textAbstract:
Rapid and unprecedented ecological change threatens the functioning and stability of ecosystems. On coral reefs, global climate change and local stressors are reducing and reorganizing habitat-forming corals and associated species, with largely unknown implications for critical ecosystem functions such as herbivory. Herbivory mediates coral–algal competition, thereby facilitating ecosystem recovery following disturbance such as coral bleaching events or large storms. However, relationships between coral species composition, the distribution of herbivorous fishes and the delivery of their functional impact are not well understood. Here, we investigate how herbivorous fish assemblages and delivery of two distinct herbivory processes, grazing and browsing, differ among three taxonomically distinct, replicated coral habitats. While grazing on algal turf assemblages was insensitive to different coral configurations, browsing on the macroalga Laurencia cf. obtusa varied considerably among habitats, suggesting that different mechanisms may shape these processes. Variation in browsing among habitats was best predicted by the composition and structural complexity of benthic assemblages (in particular the cover and composition of corals, but not macroalgal cover), and was poorly reflected by visual estimates of browser biomass. Surprisingly, the lowest browsing rates were recorded in the most structurally complex habitat, with the greatest cover of coral (branching Porites habitat). While the mechanism for the variation in browsing is not clear, it may be related to scale-dependent effects of habitat structure on visual occlusion inhibiting foraging activity by browsing fishes, or the relative availability of alternate dietary resources. Our results suggest that maintained functionality may vary among distinct and emerging coral reef configurations due to ecological interactions between reef fishes and their environment determining habitat selection.

Full textAbstract:
Regeneration of northern white-cedar ( Thuja occidentalis L.) is often deficient after harvesting in mixedwood stands growing on mesic sites even where browsing pressure is low. We compared the effectiveness of silviculture treatments on early regeneration of white-cedar after single-tree selection cutting (25% of basal area removed), shelterwood seed cut (50% of basal area removed), and group selection cutting (gaps of 625 m2) in three yellow birch ( Betula alleghaniensis Britt.) – softwood uneven-aged stands in Quebec, Canada. Three years after harvesting, the combination of factors that maximized abundance of white-cedar seedlings was single-tree selection cutting with artificial seeding on exposed mineral seedbeds (68.8% of plots with the presence of white-cedar). Early growth of planted white-cedar seedlings (40 cm tall) and biomass production were proportional to light availability, i.e., best under group selection cutting (mean height increment = 14.8 cm/year, mean root collar diameter increment = 3.0 mm/year). Browsing pressure has regional impacts depending on herbivore occupancy of the area. Our study was conducted near the northern limit of white-tailed deer ( Odocoileus virginianus (Zimmerman, 1780)), and deer were locally absent, while snowshoe hare ( Lepus americanus Erxleben, 1777) did not have a consistent effect on seedling abundance and early survival, limiting height growth only during the first year following planting.

Full textAbstract:
In this paper, the prediction of over-the-top service quality is discussed, which is a promising way for mobile network engineers to tackle service deterioration as early as possible. Currently, traditional mobile network operation often takes appropriate remedial measures, when receiving customers’ complaints about service problems. With the popularity of over-the-top services, this problem has become increasingly serious. Based on the service perception data crowd-sensed from massive smartphones in the mobile network, we first investigated the application of multi-label ReliefF, a well-known method of feature selection, in determining the feature weights of the perception data and propose a unified multi-label ReliefF (UML-ReliefF) algorithm. Then a feature-weighted multi-label k-nearest neighbor (ML-kNN) algorithm is proposed for the key quality indicators (KQI) prediction, by combining the UML-ReliefF and ML-kNN together in the learning. The experimental results for web browsing service show that UML-ReliefF can effectively identify the most influential features of the data and thus, lead to better performance for KQI prediction. The experiments also show that the feature-weighted KQI prediction is superior to its unweighted counterpart, since the former takes full advantage of all the features in the learning. Although there is still much room of improvement in the precision of the prediction, the proposed method is highly potential for network engineers to find the deterioration of service quality promptly and take measures before it is too late.

Full textAbstract:
It has recently been argued that the probable high cost of travel for sauropod dinosaurs would have made exploiting high forage energetically attractive, if this reduced the need to travel between food patches. This argument was supported by simple calculations. Here, we take a similar approach to evaluate the energetics of foraging close to the ground. We predict that small extensions of the neck beyond the minimum required for the mouth to reach the ground bring substantial energetic savings. Each increment of length brings a further saving, but the sizes of such benefits decrease with increasing neck length. However, the observed neck length of around 9 m for Brachiosaurus (for example) is predicted to reduce the overall cost of foraging by 80 per cent, compared with a minimally necked individual. We argue that the long neck of the sauropods may have been under positive selection for low foraging (instead of, or as well as, exploitation of high foraging), if this long neck allowed a greater area of food to be exploited from a given position and thus reduced the energetically expensive movement of the whole animal.

We evaluated the effect of browsing experience, nutritional quality and secondary compounds of forage resources, and the interaction between these factors on the selection and intake of goats in a cafeteria trial. Twelve juvenile Criollo goats from 7 to 9 months of age, weighing 22 ± 3 kg, were divided into two groups: (a) browser goats group (n = 6, BG), and (b) naïve goats group (n = 6, NG), formed according to their previous browsing experience (with and without, respectively). Animals were housed in individual pens. The cafeteria experiment lasted 21 days considering pen adaptation, foliage adaptation, and measurements, which included the selection index (SI) of experimental forage resources (Chesson’s alpha) and their dry matter intake (DMI/Kg0.75), using a multiple Latin square design. Furthermore, correlation and regression analyses were used to assess the relationship between the aforementioned factors. The NG did not show any selection pattern, while the BG selected Piscidia piscipula and Senegalia gaumeri (p = 0.0002). The BG consumed smaller amounts of secondary compounds compared to NG (p = 0.0001). In the BG, the flavonoids affected negatively their selection (R2 = 97.51, p = 0.0001), while the DMI was affected by in vitro DM digestibility and flavonoids (R2 = 99.85; p = 0.0001). For the NG, the crude protein and organic matter contents were associated with DMI, but none had a significant relationship with SI. The BG selected and consumed forages with suitable nutritional quality avoiding those with high content of secondary compounds such as flavonoids. Conversely, NG did not show a clear pattern for their selection or intake.

Full textAbstract:
Mediterranean forest rangelands offer an important feed source for goats. Concerns about grazing strategies and management schemes in order to ensure the rangeland sustainability of Southern Mediterranean forest have revived interest in the foraging behavior of goats. This study was conducted to investigate the seasonal changes of feeding behavior of grazing goats in the Southern Mediterranean forest rangeland of Northern Morocco during two consecutive years beginning in 2016. The direct observation method was used to compare diet composition, intake rate, and diet selectivity of goats during three seasons (spring, summer, and fall). Bite mass of each plant species selected by goats was estimated using hand-plucked simulation. The optimal foraging theory was used as a tool to explain the goats foraging decisions. Bite mass range was extremely wide and varied seasonally. The goats’ diet was largely composed of Cistus spp., Lavandula stoechas, Quercus spp., and Myrtus communis. The result shows that the smaller the bite mass, the higher the biting rate, leading to increased short term intake rates. The selection of various plant species during fall and summer enlarged the diet diversity of goats. As expected, goats preferred trees and some shrubs despite their low availability. Consequently, the most available species is not necessarily the most positively selected. Particular high and positive selection of Quercus suber was observed over seasons. The outcomes confirm the high adaptability and ability of goats to select a woody species across seasons. Knowledge about forage availability and the feeding behavior of goats could be used as the first guide for rangeland managers to ensure herd and forest sustainability.

We propose an interactive video browsing tool for supporting content management and selection in postproduction. The approach is based on a process model for multimedia content abstraction. A software framework based on this process model and desktop and Web-based client applications are presented. For evaluation, we apply two TRECVID style fact finding approaches (retrieval and question answering tasks) and a user survey to the evaluation of the video browsing tool. We analyze the correlation between the results of the different methods, whether different aspects can be evaluated independently with the survey, and if a learning effect can be measured with the different methods, and we also compare the full-featured desktop and the limited Web-based user interface. The results show that the retrieval task correlates better with the user experience according to the survey. The survey rather measures the general user experience while different aspects of the usability cannot be analyzed independently.

Abstract The aim of this study is to analyze the reasons behind users’ selection of news results on the news aggregator website, Google News, and the role that news factors play in this selection. We assume that user’s cognitive elaboration of users influences their news selection. In this study, a multi-method approach is used to obtain a complete picture of the users’ news selection reasoning: an open survey, a closed survey, and a content analysis of screen recording data. The results were determined from online news selection of 90 news results from 47 users on Google News. Different news values could be identified as relevant for selection: time-referenced news factors and news factors of social significance were shown to be more important than the news factors of deviance. News cues (presence of a picture, position of a news result, source) were identified as selection reasons regardless of the level of cognitive elaboration during the online browsing process.

"Influence of Strip Clearcuts, Deer Exclusion and Herbicide on Initial Sapling Recruitment in Northern Hardwood Forests." Forests 13, no. 7 (July 21, 2022): 1149. http://dx.doi.org/10.3390/f13071149.
Full textAbstract:
Sapling recruitment in hardwood forests is often suppressed by overstory shade, interspecific competition, and browsing pressure from white-tailed deer (Odocoileus virginianus Zimmerman). In some northern hardwood stands, these three interacting factors may cause persistent recruitment failure of the dominant canopy species, sugar maple (Acer saccharum Marsh.), into the sapling size class. In this study, we compared initial (two-year) sugar maple and hophornbeam (Ostrya virginiana ((Mill.) K. Koch) seedling and sapling recruitment in strip clearcuts to strip selection cuts, with combinations of herbicide and deer exclosures, in a northern hardwood forest with limited sugar maple sapling recruitment. We found that sugar maple sapling recruitment was higher in exclosures, particularly in strip clearcuts. Moreover, mixed models predicted that exclosures in strip clearcuts with herbicide tended to benefit sugar maple sapling recruitment, especially when the pre-treatment density was less than ~1500 stems ha−1. Sapling density of hophornbeam was also promoted in exclosure plots but was negatively affected by herbicide. Graminoid and Rubus spp. cover was also limited by herbicide following harvest, potentially alleviating constraints on future sugar maple sapling recruitment. Our findings indicate that sugar maple sapling recruitment in strip clearcuts is similar to strip selection cuts unless browsing pressure and interspecific competition are also alleviated.

Full textAbstract:
The co-evolved relationship between the chemical composition of plants and herbivory is fundamental in understanding diet selection of herbivores and their impacts on plants and ecosystems. However, the impact of plant secondary chemistry on mammalian herbivory is not fully understood. We investigated seasonal influences of phenolics with low molecular weight (e.g., flavonoids, salicylates) and plant morphology of the tea-leaved willow (Salix phylicifolia L.) on moose (Alces alces (L., 1758)) foraging. We analysed the relationship of different phenolic compounds in twigs and browsing in winter, and in leaves and the degree of leaf stripping in summer, and the role of plant morphology. In winter, higher concentrations of phenolics, e.g., myricetin-related compounds (belonging to the flavonoids), had a negative impact on herbivory by moose. This impact was not associated with a single compound but instead seemed to be more a result of synergistic or additive effects of different compounds. In contrast, the models for summer browsing showed a pronounced effect of plant morphology. Our analyses reveal differences in the relative importance of phenolics of low molecular weight and plant morphology on diet selection between seasons. These findings are relevant for understanding feeding decisions and mechanisms deterring mammalian herbivores known for shaping the vegetation on the ecosystem level.

In this paper we consider the problem of effective browsing of collections of images. In particular, we address those situations where it is necessary to find a limited number of images satisfying certain criteria, as well as the very common case in which the user, not having a clear idea about what to search, needs to explore the entire picture database to identify what he or she simply likes. The approaches we propose try to find good trade-offs between browsing time and quality of the exploration. The article has a twofold purpose: on the one hand, it presents a selection of the new image display methods we have developed in the last years, which differentiate from those considered to date by the Information Visualization community; on the other hand, it illustrates the results obtained through comparative tests performed on a subset of the developed display modes, with the main aim to prove the feasibility of their use as substitutes for the usual "grid" arrangement.

Full textAbstract:
Scale dependence is a fundamentally important topic in ecology because it determines whether results can be generalized over different spatial scales. We studied the relationship between forage consumption by moose ( Alces alces (L., 1758)) and forage availability across six nested spatial scales in south-central Sweden. By using multiple regression, we concluded that the amount of available forage was the best single variable explaining absolute consumption, irrespectively of scale. Forage species diversity, site productivity, and moose density were also important for predicting forage consumption, but their effects differed across the different spatial scales. A multiple regression including forage availability, moose density, site productivity, and forage diversity explained between 31% and 49% of the variation in forage consumption. The importance of a moose index as an explanatory variable decreased with increasing spatial scale, whereas the importance of site productivity increased. According to model selection based on Akaike's information criterion, the same model was ranked highest at the four smallest spatial scales, whereas the top-ranked models at the two largest spatial scales differed. Furthermore, the relationship between consumption and forage availability changed from underutilization at small scales to proportional use at the home range level. Thus, for a comprehensive understanding of moose browsing in relation to food resources, we conclude that a multi-scale approach is necessary.

Full textAbstract:
Vertical selection is the task of selecting the most relevant verticals to a given query in order to improve the diversity and quality of web search results. This task requires not only predicting relevant verticals but also these verticals must be those the user expects to be relevant for his particular information need. Most existing works focused on using traditional machine learning techniques to combine multiple types of features for selecting several relevant verticals. Although these techniques are very efficient, handling vertical selection with high accuracy is still a challenging research task. In this paper, we propose an approach for improving vertical selection in order to satisfy the user vertical intent and reduce user’s browsing time and efforts. First, it generates query embeddings vectors using the doc2vec algorithm that preserves syntactic and semantic information within each query. Secondly, this vector will be used as input to a convolutional neural network model for increasing the representation of the query with multiple levels of abstraction including rich semantic information and then creating a global summarization of the query features. We demonstrate the effectiveness of our approach through comprehensive experimentation using various datasets. Our experimental findings show that our system achieves significant accuracy. Further, it realizes accurate predictions on new unseen data.

In order to ensure the quality of resource recommendation and solve the problems of low recommendation accuracy, long recommendation time, and high data loss rate in the process of resource recommendation in traditional methods, a personalized recommendation system of English teaching resources based on the multi-K nearest neighbor regression algorithm is designed. According to the overall architecture of the personalized recommendation system of teaching resources, this study designs the resource browsing function module, teaching resource detailed page recommendation module, and teaching resource database. Based on the basic idea of the multi-K nearest neighbor regression algorithm, in order to avoid the loss of important data in English teaching resource recommendation and reduce the data loss rate, a missing data reconstruction algorithm of English teaching resources is proposed. Finally, the path interest of student users is considered from the selection of browsing path and access time to realize the personalized recommendation of English teaching resources. The experimental results show that the system has high resource recommendation accuracy, short recommendation time, and low data loss rate.

Full textAbstract:
Research Highlights: Regenerating northern white-cedar (Thuja occidentalis L.) is challenging throughout much of its range. This study attempts to relate differences in natural regeneration to stand- and seedbed-level factors. Background and Objectives: Lack of regeneration of northern white-cedar is often attributed to overbrowsing by white-tailed deer (Odocoileus virginianus Zimmerman) because white-cedar is a preferred winter browse species. However, there are many other factors that may contribute to regeneration failure for white-cedar including its specific seedbed requirements and competition from other, often faster-growing trees and shrubs. Materials and Methods: We surveyed five mature white-cedar stands in Wisconsin, USA that have had little to no management in the past 50+ years to find stem densities of natural white-cedar regeneration in three height classes. We also collected data at each stand on potential predictor variables including overstory attributes, competitive environment, seedbed, and browsing by deer. We used model selection to create separate models to predict stem density of each white-cedar regeneration height class. Results: None of the measures of deer browsing used in this study were found to be associated with white-cedar regeneration. Soil pH, competition from other seedlings and saplings, and stem density of white-cedar in the overstory were found to be potentially associated with white-cedar regeneration. Conclusions: While browsing by deer is likely a factor affecting white-cedar regeneration in many areas, this study highlights the challenge of quantifying deer browse effects, as well as showing that other factors likely contribute to the difficulty of regenerating white-cedar.

Full textAbstract:
Abstract:This study tested the hypothesis that the black rhinoceros browses more on termitaria than off termitaria vegetation due to elevated soil and foliar nutrient levels on termitaria. We investigated the role of termitaria in providing nutrient-rich forage for the black rhinoceros, by comparing the preference (selection ratio) for vegetation occurring on and off termitaria, and then testing its relationship with foliar nutrient concentrations. Soil nutrients, bite intensity, tree species diversity, vegetation density, canopy cover and basal area were also surveyed on and off termitaria. We sampled 25 termite mounds together with their corresponding control plots in Chipinge Safari Area, Zimbabwe. Soil and foliar N, P, K, Ca and Na concentrations were greater on termitaria than off termitaria, with approximately twice the concentration of these nutrients. Browse preference followed the between-site differences in soil and foliar nutrient concentrations, with higher selection ratios and bite intensities for vegetation on termitaria than off termitaria. Diospyros quiloensis was the most preferred browse species whilst Combretum imberbe, Kigelia africana and Strychnos innocua were the least. In conclusion, the black rhino preferred vegetation on termitaria to that in the surrounding matrix, and utilization of vegetation can be influenced by the soil substrate on which tree species grow.

Full textAbstract:
The study analysed a 15-years experiment focusing on the effect of silvicultural treatment (increment thinning) and red deer browsing on the structure and regeneration processes of common yew (Taxus baccata L.) on a series of four permanent experimental plots in the Nature Reserve Pavelcovo. The reserve Pavelcovo is an age-differentiated natural forest with a typical two-layer structure. The fragmented upper layer is formed of common beech, silver fir, sycamore, Norway maple,Wych elm, common ash and European larch. The lower layer,which is relatively continuous, is formed primarily of common yew. Concerning forest typology, a major part of the reserve was classified to Fagetum tiliosum. The analysis of the effect of the thinning from above with negative selection confirmed a significant increment of yew crown diameters. Concerning the damage on yews with DBH over 2 cm by red deer browsing, a positive correlation was observed: with the increasing breastheight diameter, the share of yew trees damaged by barking increased. Red deer at the present counts becomes a serious factor disturbing natural regeneration processes of yew and causing its gradual decline in the forest ecosystems under investigation. The analysis of the efficiency of a thinning from above on the improvement of ecological conditions for seed germination, establishment, survival and growth of yew seedlings showed that in case of a continuous lower layer, the amount of the transmitted light is insufficient and is one of the principal causes of the auto-reduction of this tree species. A better survival of yew would require an intervention into the lower yew layer mainly through a sanitary selection.

Full textAbstract:
Coral reef resilience is greatly influenced by herbivory. There is a need to identify key fish species fulfilling this critical function in biogeographically distinct regions. This experimental in situ study investigated fish herbivory in coral reefs of the lower Gulf of Thailand characterized by a considerably low herbivorous fish biomass and diversity, but high live coral and low macroalgal cover. This provided an intriguing situation for macroalgal browsing research. Visual census techniques assessed the abundance of local herbivorous fish species, and filmed single-choice assays using the macroalga Turbinaria evaluated mass-standardized bites (ms-bites) and biomass removal. Multiple-choice assays offering four locally abundant macroalgae identified specific biomass removal and ms-bites to uncover selection and avoidance patterns of observed fish species. The rabbitfish Siganusvirgatus constituted only 39% of herbivore biomass but accounted for 90% of ms-bites. In multiple-choice assays, fishes took most (61%) bites on Sargassum, followed by Padina (28%) and Turbinaria (11%), while Lobophora was avoided. S. virgatus exhibited the most generalized browsing pattern of all species observed. Coinciding with recent studies, our findings suggest that S. virgatus plays a key functional role in reefs characterized by low diversity of herbivores and low functional redundancy.

Internet-related electricity consumption is rising rapidly as global Internet users spend more than 6.5 h per day online. Open source ad blockers have the potential to reduce the time and thus electricity spent using computers by eliminating ads during Internet browsing and video streaming. In this study, three open source ad blockers are tested against a no-ad blocker control. Page load time is recorded for browsing a representative selection of the globally most-accessed websites, and the time spent watching ads on videos is quantified for both trending and non-trending content. The results show that page load time dropped 11% with AdBlock+, 22.2% with Privacy Badger, and 28.5% with uBlock Origin. Thus, uBlock Origin has the potential to save the average global Internet user more than 100 h annually. The energy conserved if everyone in the United States used the open source ad blocker would save over 36 Americans lives per year if it were to offset coal-fired electricity generated-based pollution. In the United States, if all Internet users enabled Privacy Badger on their computers, Americans would save more than $91 million annually. Globally, uBlock Origin could save consumers more than $1.8 billion/year. Open source ad blockers are a potentially effective technology for energy conservation.

Abstract We examined spring and summer use of woody browse by white-tailed deer (Odocoileus virginianus) in forest gaps created by group selection timber harvest in a South Carolina bottomland hardwood forest during 1995 and 1996. Percent available twigs browsed, relative abundance, and relative use were calculated for each species with more than 50 twigs sampled. We used chi-square analysis to rate species as preferred, proportional, or low use. Total percent browsed was low in both years (2.5% in 1995; 3.0% in 1996). In 1995, 6 species were rated as high use, 4 species as proportional use, and 10 species as low use. In 1996, 6 species were rated as high use, 7 as proportional use, and 9 as low use. Species ratings generally were in agreement with other food habits studies in the Southeast. Preferred browse species included red maple (Acer rubrum), winged elm (Ulmus alata), greenbrier (Smilax spp.), and black willow (Salix nigra). The low rates of browsing probably were due to low use of the study area by deer during the growing season. Deer browsing likely had little impact on regeneration of most species in this bottomland hardwood forest. South. J. Appl. For. 23(2):78-82.

Agroforestry systems (mosaics of woodlands, rangelands and croplands) managed for red deer rearing and hunting constitute a profitable and increasing form of land usage in Mediterranean Spain since the 1960s. As a consequence, stocking rates have increased dramatically and are now frequently over 50 individuals/km2. That situation has created a new problem of sustainability for that new type of agroforestry systems. This paper analyses the selection of woody species by red deer and the effect of that species on Mediterranean shrublands at the Montes de Toledo range in central Spain. Selection indexes were measured for 33 woody species by comparing percentages of utilization (browsing) with percentages of availability. Phillyrea angustifolia, Arbutus unedo and Quercus faginea showed the highest selection indexes while Thymus mastichina, Daphne gnidium and Pinus pinea showed the lowests ones. Food preferences showed no significant variation with different red deer stocking rates. The effect of red deer stocking rates around 35 individuals/km2 on woodlands and shrublands seems to be over the sustainability level even though sown pastures and croplands are available for red deer populations within the study area.

Full textAbstract:
The recent development of three dimensional (3D) display technologies has resulted in a proliferation of 3D video production and broadcasting, attracting a lot of research into capture, compression and delivery of stereoscopic content. However, the predominant design practice of interactions with 3D video content has failed to address its differences and possibilities in comparison to the existing 2D video interactions. This paper presents a study of user requirements related to interaction with the stereoscopic 3D video. The study suggests that the change of view, zoom in/out, dynamic video browsing, and textual information are the most relevant interactions with stereoscopic 3D video. In addition, we identified a strong demand for object selection that resulted in a follow-up study of user preferences in 3D selection using virtual-hand and ray-casting metaphors. These results indicate that interaction modality affects users’ decision of object selection in terms of chosen location in 3D, while user attitudes do not have significant impact. Furthermore, the ray-casting-based interaction modality using Wiimote can outperform the volume-based interaction modality using mouse and keyboard for object positioning accuracy.

Full textAbstract:
Background The internet has caused the explosive growth of medical information and has greatly improved the availability of medical knowledge. This makes the internet one of the main ways for residents to obtain medical information and knowledge before seeking medical treatment. However, little has been researched on how the internet affects medical decisions. Objective The purpose of this study was to explore the associations between internet behaviors and medical decisions among Chinese adults aged 18 or over, including whether to go to the hospital and which level of medical institution to choose. Methods With the adult residents (≥18 years old) in 12 regions including urban and rural areas taken as the research objects, the differences in medical choices of adults with various characteristics were analyzed, and generalized linear mixed models were adopted to analyze the longitudinal data of the China Health Nutrition Survey from 2006 to 2015. Results Adult groups with different ages, genders, education levels, regions, places of residence, severities of illness and injury, years of suffering from hypertension, and history of chronic diseases showed diverse medical decisions, and the differences were statistically significant (P<.05). After controlling for these potential confounding factors and taking self-care as the reference, the probability of Chinese adults who participated in online browsing activities selecting hospital care was 0.82 (95% CI 0.69-0.98; P=.03) times that of residents who did not participate in online browsing activities. In terms of medical institution choices, adults who participated in online browsing activities were 1.86 (95% CI 1.35-2.58; P<.001) times more likely to opt for municipal medical treatment than primary care. However, the effect of online browsing on the selection probability of county-level hospitals was not significant compared with primary hospitals (P=.59). Robust analysis verified that accessing the internet had a similar effect on Chinese adults’ medical decisions. Conclusions Chinese adults who use the internet are a little less likely to go to the hospital than self-care. The internet has broken down the barriers to obtain knowledge of common diseases and thus has a slight substitution effect of self-care on hospital care. Internet use may increase the probability of adults going to municipal hospitals. The rising tendency of visiting high-level medical institutions may be consequently exacerbated due to knowledge monopoly of severe and complicated diseases that is difficult to eliminate, and the increase in inconsistent and incomplete medical information online will blur the residents’ cognitive boundary of common diseases and severe diseases. Exploring the substantive impact of the internet on medical decision making is of great significance for further rational planning and utilization of the internet, in order to guide patients to appropriate medical institution.

Full textAbstract:
Social media sites such as Twitter contain large amounts of user contributed messages for a wide variety of real-world events. While some of these "event messages" might contain interesting and useful information (e.g., event time, location, participants, opinions), others might provide little value (e.g., using heavy slang, incomprehensible language) to people interested in learning about an event. Techniques for effective selection of quality event content may therefore help improve applications such as event browsing and search.In this paper, we explore approaches for finding representative messages among a set of Twitter messages that correspond to the same event, with the goal of identifying high quality, relevant messages that provide useful event information. We evaluate our approaches using a large-scale dataset of Twitter messages, and show that we can automatically select event messages that are both relevant and useful.

Online reviews exert significant influence on the sale and purchase of any product. They not only play a prominent role in the selection of hotels but are also eye openers for the hotel managers because they expose problem areas which need dire attention for the upgradation of quality. Browsing big data from multiple online platforms to find reviews is a time-consuming task. Consequently, Business intelligence is a field which collects and analyses data for customers and managers. This study analyses reviews of 7 hotels in Islamabad through the Social mention tool which gives a visual representation of the strength, sentiment,passion, and reach of each. Multi modal Sentiment Analysis theory has been applied to identify the nature of the reviews. The major findings reveal sentiment analysis of the hotels’ reviews from social media. There search helps individuals in decision making and selection of hotels; and guides the management staff for rectification.

E-bussiness has grown rapidly in the last decade and massive amount of data on customer purchases, browsing pattern and preferences has been generated. Classification of electronic data plays a pivotal role to mine the valuable information and thus has become one of the most important applications of E-bussiness. Support Vector Machines are popular and powerful machine learning techniques, and they offer state-of-the-art performance. Rough set theory is a formal mathematical tool to deal with incomplete or imprecise information and one of its important applications is feature selection. In this paper, rough set theory and support vector machines are combined to construct a classification model to classify the data of E-bussiness effectively.

Full textAbstract:
The influence of opening size on gap cohort biomass was examined in uneven-aged hemlock-hardwood forests in northeastern Wisconsin by sampling 36 canopy gaps ranging from 5 to 800 m2 in area and from 3 to 55 years of age. The standing crop of whole-tree aboveground biomass per hectare was greater in multiple-tree gaps than single-tree gaps of similar age. However, biomass production approached an asymptote at fairly small opening sizes, and 400800 m2 group selection openings did not have significantly more biomass per unit area than small multiple-tree gaps (80100 m2). Similarly, mean tree dimensions, recent height growth increments, and basal area increments for most species of gap trees approached an asymptote at an opening size of approximately 100 m2. As opening size increased, yellow birch (Betula alleghaniensis Britton) superseded eastern hemlock (Tsuga canadensis (L.) Carrière) as the species with greatest relative biomass. The selection system appears to be a viable alternative to the even-aged shelterwood system in hemlock forests where browsing pressure is not excessive, but use of group selection may require additional treatments to ensure that some gaps >100 m2 are captured by hemlock.

Full textAbstract:
This study intended to know Iberian wild goat Capra pyrenaica Schinz, 1838 feeding strategy in two proximate mountains it recently recolonized, Gerês and Amarela (Peneda-Gerês National Park, PGNP, Portugal). For that purpose we studied species dietary composition using faecal diet microhistological determinations and also its diet selection. Albeit wild goat exhibited an intermediate browse - graze behaviour in the two areas, grazing was more pronounced in Gerês while browsing in Amarela. Both areas presented a dietary shift in spring consisting in an increase on the consumption and preference for graminoids. This feeding strategy extended through summer only in Amarela. Results obtained are congruent with wild goat generalist feeding behaviour in other regions of the Iberian Peninsula and suggest that species feeding strategy in PGNP respond to spatial patterns of resources, specifically of graminoids, and to livestock stocking rates and management.
