从黄山市看旅游发展模式转型的必然性与实施策略

旅游发展模式对旅游业的发展质量有重大影响,在不同的发展阶段应该选用不同的发展模式.黄山市现行数量增长型发展模式已经导致以下弊端：资源配置效率降低,旅游企业经济效益下滑;过度追求接待规模,往往造成生态环境恶化;无限制地扩大接待量,必然导致游客评价度降低：乡村旅游的低水平开发,无法给村民带来预期的经济收益与社会进步.黄山市必须分阶段推行效益增长型发展模式,其实施策略包括：第一,以科学合理的规划为指导,提高资源的配置效率;第二,以世界一流旅游目的地建设为目标,完善旅游产品体系,深度发掘旅游资源的经济价值：第三,进一步发挥屯溪的中心城市作用,提高黄山市旅游产业的集聚程度;第四,构建新型空问竞合模式,通过区域合作提升旅游目的地的影响力与竞争力.     

披文仰贤 观字赏心——赏读明代状元赵秉忠《山其山集·自叙》

明代状元赵秉忠的《山其山集.自叙》用作者的草体手书印制。本文对《自叙》用正楷按原文转行排版,详加注释,译成现代文,并根据作者当时的处境和遭遇,对《自叙》的内容进行了探幽索隐的尝试。     

企业员工隐性知识交流能力评价模型

为评价企业员工隐性知识交流能力,提出隐性知识交流能力评价模型。首先,通过问卷调查获得企业员工隐性知识流转情况,并据此建立隐性知识流转网络。其次,根据隐性知识流转网络以及Page Rank算法的基本思想建立隐性知识交流能力评价模型。在该模型中,能经常与别人交流的员工,交流能力强;与交流能力强的人交流,自身的交流能力也会提升;每个人用于知识交流的精力是有限的;每个人不会把所有的隐性知识分享给别人。最后讨论分析模型的解。     

高师“初等数论＂课程改革探讨

“初等数论”是高师院校数学专业的一门传统专业选修课,在中小学各级数学竞赛、组合数学、密码学等方面都有广泛应用,是一门重要的数学专业课程。但近几十年来,数论课无论教材内容还是教学方法变化都不大,为了适应当前中小学和高校课改的需要,我们有必要对该课进行出一些改革探讨。本文从教学内容和教学方法上分析了传统的数论教学中存在的不足,然后提出了针对性的改革措施。     

Enhancing young children's arithmetic skills through non-intensive,computerised kindergarten interventions: A randomised controlled study

Children in kindergarten were randomly assigned to adaptive computerised counting or comparison interventions, or to a business-as-usual control group. Children in both intervention groups, including children with poor calculation skills at the start of the intervention, performed better than controls in the posttest. However the effects of training held in grade 1, playing serious counting games improving number knowledge and mental arithmetic performances, and playing serious comparison games, only enhanced the number knowledge proficiency in grade 1. The value of these short periods of intensive gaming in kindergarten are discussed as a look-ahead approach to enhance arithmetic proficiency.

An efficient page ranking approach based on vector norms using sNorm(p) algorithm

In the whole world, the internet is exercised by millions of people every day for information retrieval. Even for a small to smaller task like fixing a fan, to cook food or even to iron clothes persons opt to search the web. To fulfill the information needs of people, there are billions of web pages, each having a different degree of relevance to the topic of interest (TOI), scattered throughout the web but this huge size makes manual information retrieval impossible. The page ranking algorithm is an integral part of search engines as it arranges web pages associated with a queried TOI in order of their relevance level. It, therefore, plays an important role in regulating the search quality and user experience for information retrieval. PageRank, HITS, and SALSA are well-known page ranking algorithm based on link structure analysis of a seed set, but ranking given by them has not yet been efficient. In this paper, we propose a variant of SALSA to give sNorm(p) for the efficient ranking of web pages. Our approach relies on a p-Norm from Vector Norm family in a novel way for the ranking of web pages as Vector Norms can reduce the impact of low authority weight in hub weight calculation in an efficient way. Our study, then compares the rankings given by PageRank, HITS, SALSA, and sNorm(p) to the same pages in the same query. The effectiveness of the proposed approach over state of the art methods has been shown using performance measurement technique, Mean Reciprocal Rank (MRR), Precision, Mean Average Precision (MAP), Discounted Cumulative Gain (DCG) and Normalized DCG (NDCG). The experimentation is performed on a dataset acquired after pre-processing of the results collected from initial few pages retrieved for a query by the Google search engine. Based on the type and amount of in-hand domain expertise 30 queries are designed. The extensive evaluation and result analysis are performed using MRR, [email protected], MAP, DCG, and NDCG as the performance measuring statistical metrics. Furthermore, results are statistically verified using a significance test. Findings show that our approach outperforms state of the art methods by attaining 0.8666 as MRR value, 0.7957 as MAP value. Thus contributing to the improvement in the ranking of web pages more efficiently as compared to its counterparts.

各代状元在官场的发展空间——历代状元遭际考索之二

各代状元在官场的发展空间是很不相同的:状元宰相比例最高的是宋,最低的是唐;状元高官比例最高的是宋,最低的是五代;状元被淹没比例最高的是五代,最低的是清。综之,宋代状元在官场的发展空间最为广阔。
