Kernel density estimation under negative superadditive dependence and its application for real data

In this paper, the kernel density estimator for negatively superadditive dependent random variables is studied. The exponential inequalities and the exponential rate for the kernel estimator of density function with a uniform version, over compact sets are investigated. Also, the optimal bandwidth rate of the estimator is obtained using mean integrated squared error. The results are generalized and used to improve the ones obtained for the case of associated sequences. As an application, FGM sequences that fulfil our assumptions are investigated. Also, the convergence rate of the kernel density estimator is illustrated via a simulation study. Moreover, a real data analysis is presented.     

What are you thinking? Acculturation as an activating event for negative evaluative beliefs among Latinos/as

Negative evaluative beliefs and other cognitive structures have been tied to psychological distress across various populations but have not been sufficiently incorporated into acculturation models. The current study examines the relationships between acculturation and various activating events and mediating sources of support related to negative evaluative beliefs among people of Mexican descent (N = 319). Overall, model variables explained 26% of the variance in negative evaluative beliefs. Acculturation, marital commitment, and social capital associated with friends were negatively related to negative evaluative beliefs. Conversely, single relationship status, marital reward value, psychosocial stressors, and bridging social capital were positively related, and likely serve as activating events for negative evaluative beliefs. Identifying mechanisms related to psychological distress as well as supportive structures may help in constructing interventions that will address the specific needs of different groups. Future research should continue to explore appraisal and associated beliefs in acculturation models to understand why acculturative experiences may become stressful.     

Modeling stereotypes and negative self‐stereotypes as a function of interactions among groups with power asymmetries

Stereotypes is one of the most researched topics in social psychology. Within this context, negative self‐stereotypes pose a particular challenge for theories. In the current work, we propose a model that suggests that negative self‐stereotypes can theoretically be accounted for by the need to communicate in a social system made up by groups with unequal power. Because our theory is dynamic, probabilistic, and interactionist, we use a computational simulation technique to show that the proposed model is able to reproduce the phenomenon of interest, to provide novel accounts of related phenomena, and to suggest novel empirical predictions. We describe our computational model, our variables' dynamic behavior and interactions, and link our analyses to the literature on stereotypes and self‐stereotypes, the stability of stereotypes (in particular, gender and racial stereotypes), the effects of power asymmetries, and the effects of intergroup contact.

“末位淘汰”浅析

末位淘汰制是绩效考核的一种制度。本文从一个较全面的角度,指出末位淘汰制的根本目的和积极作用,分析其负面效应,重点探讨应慎用此制度并指出实施中应注意的问题。     

网络负面问题及伦理思考

网络文明的到来给人类的政治、经济、文化教育、社会生活方式等带来了深刻的变化,同时也带来了诸如信息欺诈、黄色泛滥、信息安全受损、网民人格异化等网络负面问题.产生网络负面问题的伦理根源是网络自身的特点弱化了传统伦理的约束力;网络空间的道德冲突使网民陷入道德相对主义之中;网络法律和道德建设的滞后使网络负面问题有可乘之机;网民自我宣泄和自我表现的心理要求促使了网络负面问题的形成.加强网络法制建设、整合传统伦理资源、扬弃西方网络伦理理论、强化网民的内在道德自觉,是消除网络负面行为的有效途径.     

广告语言中的修辞手法

广告语言属于文学性语言,在广告语言的创作中,需要调动各种修辞手法使语言增加魅力,吸引受众。消极修辞以其平易质朴的特点能产生强烈的艺术感染力,积极修辞更是以其审美惊奇感和审美惊奇感给受众以极大的冲击力。积极修辞有多种修辞手法,都可以在广告语言中得到合理运用,在很多广告语言中则需要综合运用多种修辞手法,以加强表达效果,如比喻、比拟、夸张、借代、对偶、仿词等。     

负面清单制度的国际经验及其对上海自贸区的启示

负面清单作为上海自贸区改革一大亮点,体现了我国开始着手建立高标准的投资规则。国外的负面清单制度已发展得较为成熟,无论是多边协定NAFTA,或是各双边协定,其负面清单模式都可为上海自贸区的建设提供经验和启示。在上海自贸区负面清单模式推行中,应对重点行业实施重点保护,将负面清单制度化,使经济开放与经济安全相平衡,使宏观经济管理与微观经济自由相平衡,使立法与司法制度相结合。     

手机游戏产业繁荣背后社会负面效应的规避

伴随智能手机的逐渐普及,手机游戏产业日益成为数字娱乐文化产业中的主力军。由于国内手机游戏用户数量大、年龄低的特点,以及智能手机使手机游戏呈现出游戏载体智能化、游戏软件多样化、厂商利益链条化、政府监管复杂化等新特点,手机游戏产业存在游戏软件安全性、合法性以及游戏内容健康性等社会负面问题。为使手机游戏产业健康发展,制作商应把效益与文化建设相融合;用户提高安全意识,家长转变对游戏的态度,重视但不过分夸大游戏的负面效应;政府制定游戏分级制度、加大对公益类、教育类游戏软件开发的支持、保护手机游戏软件知识产权,争取把手机游戏产业打造成文化产业链中新的“金蛋”。     

对行政诉讼调解制度的冷思考

行政诉讼调解制度对当下中国的行政诉讼法发展有着不可忽视的消极作用,它将行政诉讼的目的定位为解决纠纷,淡化了行政诉讼保护相对人合法权益的目的,妨碍了行政诉讼独特的宪政功能的发挥,并导致了行政法规则在诉讼中的模糊化,使行政诉讼所承担的对行政法的告示、指引、预测、教育等作用无从发挥,行政违法的责任也随之淡化。而学界肯定行政诉讼调解制度的理由如行政裁量权的存在、中国无讼厌讼传统、外国存在相关制度等,均无法成立。由此,中国在当下不应建立行政诉讼调解制度。
