感知易用性会影响网络游戏中虚拟商品的使用意愿么?——感知有用性和玩家神经质的作用

基于技术接受模型考察了网络游戏中虚拟商品感知易用性对其使用意愿的影响,以及感知有用性、玩家神经质在其中的作用。采用虚拟商品使用意愿问卷、感知易用性问卷、感知有用性问卷和大五人格量表神经质分量表对559名有过网络游戏经验的大学生进行调查。结果显示:(1)虚拟商品的感知易用性可显著正向预测使用意愿;感知有用性在两者间起中介作用;(2)虚拟商品感知有用性的中介作用受到玩家神经质的调节:对于低神经质的玩家,该间接效应显著;而对于高神经质的玩家,该间接效应不显著。

Selecting a new technology strategy using multiattribute,multilevel decision trees

Research indicates that selecting a strategy to best exploit a new technology is a complex decision-making process. The task involves making a series of decisions with multiple alternatives, each to be evaluated by multiple criteria whose values have high levels of uncertainty. This paper presents a methodology for modelling a new technology decision using decision trees and an optimizing algorithm. A problem of a mining company considering the adoption of new technology is used to illustrate the decision-making task and modelling methodology. A numerical solution to the case demonstrates the potential of the optimizing technique in strategy selection.     

A multi-objective mathematical programming problem with fuzzy relation constraints

In this study we discuss the problem of multi-objective mathematical programming with constraints defined by ‘max-min’ composite fuzzy relation equations. Since the feasible region is normally non-convex, the properties of the efficient points of a non-convex feasible region under multi-objectives are investigated and illustrated by examples. The necessary and sufficient conditions are proposed and proved. To facilitate decisions, a procedure that transforms these efficient points of an interval-valued decision space into a constant-valued decision space is proposed when the level of confidence is given by a decision maker. Then the transformed problem becomes a multi-attribute decision problem that can be evaluated by Yager's method to find the optimal alternative.     

The Role of Professional Training Experiences and Manualized Programs in ABA Providers’ Use of Parent Training With Children With Autism

Parent training, in which providers teach parents intervention strategies to promote their children’s skill acquisition and/or behavior management, is considered a best practice in the treatment for children with autism spectrum disorder (ASD) and yet is underutilized in community settings. The present study examined the role of training experiences and manual use in promoting the use of parent training by community providers who serve children with ASD. Applied behavior analysis (ABA) providers (N = 1,089) from across the United States completed self-report questionnaires online. The total number of professional training experiences related to parent training significantly predicted the extensiveness of providers’ use of parent training. Receiving supervision in parent training, being trained in a specific parent training approach, taking a course related to parent training, and participating in self-guided learning (e.g., webinar) were unique predictors of parent training extensiveness. While only 15% of ABA providers used manualized parent training programs, using a manual was also a unique predictor of parent training extensiveness. Parallel multiple mediator analyses demonstrated that family-, provider-, and organization-level barriers all partially mediated the relationship between number of training experiences and parent training extensiveness; only provider- and organization-level barriers mediated the relationship between manual use and parent training extensiveness. Recommendations for training and supporting providers at the pre-service and in-service levels are discussed as a means of increasing access to parent training for children with ASD in community settings.     

Toward law–gospel harmony in Lutheran theology and ethics

Lutheran antipathy toward the law is harmful to Christian ethics. This antipathy arises from the false notion that law and gospel are opposed. However, the Lutheran Confessions show that law–gospel distinction does not necessarily imply law–gospel opposition. When law and gospel are properly defined, they interrelate harmoniously within a multiperspectival model of Christian ethics. Moreover, the third use of the law then emerges as the basic and primary use.     

Facilitating Adolescent Well‐Being: A Review of the Challenges and Opportunities and the Beneficial Roles of Parents,Schools, Neighborhoods,and Policymakers

Adolescents face exceptional challenges and opportunities that may have a lifelong impact on their consumption and personal and societal well‐being. Parents, community members (schools and neighborhoods), and policymakers play major roles in shaping adolescents and influencing their engagement in consumption behaviors that are either developmentally problematic (e.g., drug use and unhealthy eating) or developmentally constructive (e.g., academic pursuits and extracurricular activities). In this article, we discuss two main topics: (a) the challenges and opportunities that characterize adolescence, based primarily on research in epidemiology and neuroscience, and (b) the ways that parents, community members, and policymakers can facilitate positive adolescent development, based on research from many disciplines including marketing, psychology, sociology, communications, public health, and education. Our goal is to summarize the latest scientific findings that can be used by various stakeholders to help adolescents navigate this turbulent period and become well‐adjusted, thriving adults.     

孤独感和手机成瘾的关系:一项元分析

孤独感与手机成瘾均是当下生活中较为常见的现象, 诸多研究基于不同的理论视角探讨了两者间的内在联系, 但研究结果却存在很大分歧。为明确两者之间的整体关系, 以及产生分歧的原因, 对检索后获得的121项研究(124个效应值)使用随机效应模型进行了元分析。结果发现:孤独感与手机成瘾存在中等程度的正相关(r = 0.25, 95% CI = [0.23, 0.27]); 两者的相关性受被试年龄群体的调节, 成年人群体中的相关系数显著高于青少年群体, 但两者的相关性不受性别、孤独感和手机成瘾测量工具的影响。结果表明孤独感与手机成瘾关系密切, 支持了补偿性网络使用理论和自我调节缺陷模型。未来应加强纵向研究或实验研究进一步揭示孤独感与手机成瘾的作用方向。     

Development of rules and strategies: balancing the old and the new

The experiments described in the lead articles replicate findings from previous studies of development of knowledge about balance scales, add several new findings, and raise four key questions: (a) How can rule use best be assessed? (b) How can we reconcile systematic use of rules with variable use of strategies? (c) When do children begin to use rules? and (d) How do children generate new rules? In this Reflection, we summarize current understanding of development of knowledge about balance scales and consider each of the four questions.
