Cultivated land is the most important strategic resource to ensure food security.The newly constructed quality classification system of cultivated land resources considers the cultivated land health index for the first time.How the new classification and grading index system and the quality classification results of cultivated land resources to effectively guide the preparation of municipal land space planning has become a key research direction.This paper expounds the overall design idea for quality classification of cultivated land resources and classification index system.Taking Chongzuo City as an example,through the analysis of the quality classification results of cultivated land resources in the study area,using GIS spatial analysis and factor pairwise comparison method,this paper explores the application ideas and methods of quality classification research results of cultivated land resources in the formulation of cultivated land retention target,the delineation of dominant areas of cultivated land protection,the delineation of three control lines,the comprehensive improvement of land,and ecological restoration zoning in the municipal land space planning. 展开更多

In this paper some selected items of changes in the human resources in Polish agriculture at the beginning of 2 Ist century were presented, especially the questions of employment and education of the rural areas population, including farmers. The employment, as the first of the issues, was presented against the changes in the EU and the stable but non-revolutionary character of changes in Polish agriculture was underlined. To illustrate the connections between the process of changes in agriculture and the level of education some statistic data were shown. The disproportion in education level between the urban and the rural population was exposed with the emphasis on poor education of the farmers. The author also discussed the further prospects of human resources changes in the rural area to 2035. At the same time the importance of education in the process of raising the standard of life and work of people in the rural areas was stressed. 展开更多

The membership of every target and the mathematic model of multi-level fuzzy comprehensive assessment are set up by using fuzzy theories and means in this study.Tourism resources of main scenic spots areas in Laiyuan County of Hebei Province are evaluated and classified by applying the model.The results of evaluation indicate that 10 of these scenic spots such as Baoziwo and Qingyunfeng are grade A,and 6 of them such as Yunpan Valley and Xianrenqiao are grade B.The peak forest scenic area in the Baishishan Geological Park and Shipuxia Scenic Area are grade A,and Jumayuan Scenic Area is grade B.Furthermore,suggestions are put forward based on the scientific and feasible development of tourism resources. 展开更多

This paper mainly discusses leadership soft skills, which comprise of collaboration or teamwork, communication skills, initiative, leadership ability, people development or coaching, personal effectiveness or personal mastery, planning and organizing, and presentation skills. Leaders need to be masters of soft skills because leadership is determined by those who can demonstrate their ability to drive an organization toward excellence and results. The aim of this paper is to contribute to the body of knowledge and literature in leadership soft skills for educational leaders in higher education institutions. In addition, this paper also provides exposure to administrators to understand the importance of leadership soft skills besides highlighting the two relevant models. Furthermore, it also provides an advantage to administrators in developing high quality interpersonal relationships with the people who they associate with in promoting positive working environment. Leadership soft skills can be seen as providing a vital contribution for organizations and administrators in the process of developing of quality human resource. 展开更多

Conventional resource provision algorithms focus on how to maximize resource utilization and meet a fixed constraint of response time which be written in service level agreement(SLA).Unfortunately,the expected response time is highly variable and it is usually longer than the value of SLA.So,it leads to a poor resource utilization and unnecessary servers migration.We develop a framework for customer-driven dynamic resource allocation in cloud computing.Termed CDSMS(customer-driven service manage system),and the framework’s contributions are twofold.First,it can reduce the total migration times by adjusting the value of parameters of response time dynamically according to customers’profiles.Second,it can choose a best resource provision algorithm automatically in different scenarios to improve resource utilization.Finally,we perform a serious experiment in a real cloud computing platform.Experimental results show that CDSMS provides a satisfactory solution for the prediction of expected response time and the interval period between two tasks and reduce the total resource usage cost. 展开更多

High male mating effort and high variation in female quality select for male mate choice, which may be expressed as differential investment of reproductive effort based on female value. Male reproductive effort includes investment in direct contest competition with rival males for access to females, yet variation in male-male contest behavior is rarely examined in the context of male mate choice. We examine such male response to variation in female body size, reproductive state, and female-specific ornamentation in the striped plateau lizard, Sceloporus virgatus. We housed lizards in trios of 2 size-matched males and one female for 5 days, such that all 3 lizards were physi- cally isolated and the males could see the female but not each other. We then placed males simultaneously into the female's cage and scored the interaction. Male-male aggression was not significantly affected by female body size, reproductive state, nor ornament color, but was influenced by ornament size which reliably signals the phenotypic quality of the female and her off- spring. In the presence of larger-ornamented females, males engaged in more male-male aggressive display behavior more quickly, and performed fewer high-intensity contact behaviors but were equally likely to escalate to this riskier level of fighting. Our data suggest that males adjust their energetic investment during intrasexual competitive interactions in response to variation in the contested female which, assuming males gain direct or indirect benefits from their strategic allocation of reproductive effort, fits the modern understanding of male mate choice. 展开更多

The benefits of dominance may not come without costs,particularly for males.For example,the“immunocompetence handicap hypothesis”states that males with enhanced mating success allocate resources to enhance reproductive output at a cost to their current health,whereas the“resource quality hypothesis”predicts that high-ranking males may benefit from increased reproduction and good health.Whereas the predictions from each have been well tested in captive animals and in a variety of highly social primates,fewer studies have been carried out in free-living,facultatively social animals.Using adult male yellow-bellied marmots(Marmota flaviventer),we evaluated predictions of these hypotheses by examining the relationship between social rank and 2 health indicators—fecal glucocorticoid metabolite(FCM)levels,and neutrophil/lymphocyte(N/L)ratios—after accounting for variation explained by age,body mass,and seasonality.We found that higher-ranking males tended to have a lower N/L ratio(reflecting good health)than lower-ranking individuals,whereas FCM levels were not significantly related to rank.In addition,heavier male marmots had lower N/L ratios,whereas body mass was not associated with FCM levels.We also found that older adult males had lower FCM levels(reflecting less physiological stress)but higher N/L ratios than younger adults.Finally,we found that FCM levels decreased as the active season progressed and FCM levels were associated with the time of the day.Overall,our results suggest that socially-dominant male marmots enjoyed better,not worse health in terms of lower N/L ratios. 展开更多
