动态主机配置协议是缓解互联网中IP地址可分配数量不足、提高主机配置管理效率的重要技术手段,被广泛应用在各种园区网络组建中,是计算机专业学生必须掌握的一项网络工程实践技能。针对物理实验设备上进行动态主机配置协议研究与分析可操作性差、不利于实验教学的问题,分析了动态主机配置协议的基本工作过程和3种常用的配置实现方式;在企业网络仿真平台上设计网络场景进行实验仿真,以基于中继的DHCP服务为例给出实验仿真的详细过程。实验过程与分析表明,在虚拟平台下进行实验教学的方式可以更好地加深学生对动态主机配置协议原理的理解与实践技能的掌握,是一种有效的实验教学方式。  相似文献

Recent training efforts designed to strengthen student argumentation skills and decrease verbally aggressive tendencies have yielded mixed results (Rancer et al., 1997, 2000). Inherent in these efforts is the belief that an individual's use of verbal aggression is implicitly related to law argumentative behavior and a weak system for generating arguments (Infante, 1988). As an extension of this research, we examined the relationships among trait‐like argumentativeness (Infante & Rancer, 1982), trait‐like verbal aggressiveness (Infante & Wigley, 1986) (VA), and Wheeless, Preiss, and Gayle's (1997) construct of informational reception apprehension (IRA). Results indicated that two IRA factors, listening anxiety and intellectual inflexibility, were significant predictors of both aggressive communication traits. Further, both IRA factors accounted for greater variance in trait‐like argumentativeness than in trait‐like VA. Implications of these findings as they relate to Infante's (1987) “argumentative skill deficiency model,” as well as suggestions for future research are discussed.  相似文献

Four measures of affective orientation: awareness of affect as information, posses‐sion of positive feelings, and expression of positive and negative emotions were employed to examine the relationships between functional males’ and females’ affective orientations and the level of verbal abuse reported in their relationships. Females reported having higher levels of affective awareness on all four measures of affective orientation. Contrary to expectations, males’ and females’ awareness of affect as information to guide interactions and positive feelings were not associated with reported verbal abuse. Males’ and females’ expressions of negative emotions, however, were significantly negatively associated with verbal abuse in the relationships. Males’ positive emotional expressiveness was significantly negatively associated with self‐reported verbal abuse in the relationship. Functional males and females reported experiencing similar levels of verbal abuse within their relationships.  相似文献

Resumen

En este trabajo nos proponemos revisar la teoría de Luria en torno a la regulación verbal y otros campos afines de la relación lenguaje-pensamiento, según la perspectiva soviética iniciada por Vygotsky. En esta revisión se pretende efectuar un análisis detallado de las variables que están presentes en el proceso de regulación, y explicar cómo éstas se relacionan entre sí. Para alcanzar tal objetivo se incide en los siguientes aspectos: la doble vertiente cognitiva y motivational del habla reguladora; las funciones que cumplen los componentes del habla egocéntrica y/o reguladora (Vygotsky, Wertsch); y, por último, el origen de los factores activadores del habla, procedentes del estadio impulsivo y de los esquemas afectivos y de comunicación. Esta revisión se completa con la sistematización del proceso de regulación en un conjunto, que incluye las variables implicadas y un análisis de las mismas. A partir de ahí se pasa a comprobar los acuerdos y desacuerdos existentes entre las investigaciones soviéticas y occidentales; y a tratar de dar explicación de los resultados contradictorios en base a nuestra sistematización del proceso regulador, por el que, pensamos, es posible predecir la conducta a seguir por el niño en la realización de distintos tipos de tarea.  相似文献

The acknowledgement that educational achievement is highly dependent on successful reading development has led to extensive research on its underlying factors. A strong argument has been made for a causal relationship between reading and phoneme awareness; similarly, causal relations have been suggested for reading with short-term memory and rhyme awareness alike. Here a meta-analysis is presented that seeks to determine spuriousness in these factors' relationships with reading by examining each factor's unique predictive value. The results show that phoneme awareness is the strongest unique predictor. Since the meta-analysis is based on concurrent data, it is unsuited to enlighten time-order relationships, but longitudinal and experimental studies both support the notion of a causal relationship between phoneme awareness and reading, in contrast to rhyme awareness and verbal short-term memory.  相似文献

Abstract

Research examining problem representations of individuals during task performance is advancing our understanding of information processing and expertise in a variety of sports. However, few studies using similar methodology have been conducted on individuals of various competitive standards in one domain in similar contexts. This study examined problem representations of adult advanced beginners and entry-level professionals accessed during singles tennis competition (n = 12). These groups were selected to represent players with performance skills that were different from those studied previously (i.e. adult beginners and varsity players). Immediate recall and planning interviews were conducted between points during singles tennis competition. Players competed within their respective expertise groups. Verbal reports were transcribed verbatim and concepts were scored according to a model of protocol structure. Several multivariate analyses of variance were conducted on rank scores for measures of concept content and structure using the L-statistic. Entry-level professionals exhibited more advanced problem representations than advanced beginners regardless of interview type. These findings together with those of previous research suggest adaptations in long-term memory profiles with increases in performance skills. For example, beginners lacked action plan and current event profiles because they generated goals and reiterated game events during both interviews. Advanced beginners, who had better performance skills than beginners, exhibited rudimentary action plan profiles and deficient current event profiles because they generated and monitored several detailed actions related to the current context during recall interviews and generated only a few goals during planning interviews. In contrast, varsity players and professionals processed tactical information in the current context and beyond denoting the existence of both action plan and current event profiles. Varsity players, with inferior performance skills than professionals, exhibited fewer and less associated tactical concepts than professionals during both interviews.  相似文献

Abstract

Before completing a team-based dart-throwing activity, 80 undergraduates were randomly assigned to one of three pre-performance self-talk conditions: (a) self-talk statements that focused upon one's personal capabilities, (b) self-talk statements emphasizing the group's capabilities, or (c) a control condition where neutral statements were implemented. Participants in all conditions subsequently rated their confidence in their own (i.e. self-efficacy) as well as their team's (i.e. collective efficacy) capabilities, before carrying out the task. Overall, self-efficacy, collective efficacy, and performance indicators were all greatest for individuals who practised self-talk focusing on the group's capabilities, as opposed to individual-focused and neutral conditions. Findings are considered with respect to their novel theoretical contribution to the social cognition literature and their implications for fostering efficacy perceptions and team performance.  相似文献
