Appraisal models of intercultural communication apprehension among sojourners     

Rong Ma  Dale Hample 《Journal of International and Intercultural Communication》2018,11(3):192-215

We used R. S. Lazarus’ (Emotion and Adaptation. Oxford: Oxford University Press, 1991) appraisal theory of emotions to propose a theoretical model of anxiety, upon which we built two empirical models centering on intercultural communication apprehension (ICA), distinguished by timing. We tested the models in three samples: Chinese in the US (N?=?268), US Americans who studied abroad (N?=?419), and US Americans in the US (N?=?515). The models achieved good fit. The results showed that during an anticipated or actual intercultural interaction, people had multiple, potentially conflicting goals. The goal-related appraisals of the situation resulted in emotional reactions, such as ICA, as well as coping strategies. ICA and coping further influenced people’s immediacy behaviors and the intention to interact. Our empirical models supported the utility of the theoretical framework for all three samples, and provided advice for practitioners to improve sojourners’ time abroad.  相似文献   

The effects of attentional focus instructions on punching velocity and impact forces among trained combat athletes     

Israel Halperin  Dale W. Chapman  David T. Martin  Chris Abbiss 《Journal of sports sciences》2017,35(5):500-507

Research indicates that instructing athlete’s to focus on bodily movements (internal focus of attention [IFA]) may hinder performance, whereas instructing them to focus on the movement outcome (external focus of attention [EFA]) often enhances performance. Despite the importance of instructions in striking combat sports, limited research has examined the influence of IFA and EFA on performance in well-trained combat athletes. This study investigated the effects of different instructional cues on punching velocity (m · s^?1) and normalised impact forces (N · kg^?1) among intermediate (n = 8) and expert (n = 7) competitive boxers and kickboxers. Athletes completed three rounds of 12 maximal effort punches delivered to a punching integrator on three separate days. Day one was a familiarisation session with only control instructions provided. In the following two days athletes randomly received IFA, EFA or control instructions prior to each of the three rounds. Athletes punching with EFA were 4% faster and 5% more forceful than IFA (P < 0.05), and 2% faster and 3% more forceful than control (P < 0.05). Furthermore, experts punched 11% faster and with 13% greater force compared with intermediate athletes (P < 0.05). EFA led to a positive effect on punching performance and should be favoured over IFA and control instructions.  相似文献

Heart rates of high school physical education students during team sports, individual sports, and fitness activities     

Laurson KR  Brown DD  Cullen RW  Dennis KK 《Research quarterly for exercise and sport》2008,79(1):85-91

This study examined how activity type influenced heart rates and time spent in target heart rate zones of high school students participating in physical education classes. Significantly higher average heart rates existed for fitness (142 +/- 24 beats per minute [bpm]) compared to team (118 +/- 24 bpm) or individual (114 +/- 18) activities. Similar results occurred for the percentage of activity time spent within a target heart rate zone (fitness 81.7 +/- 15.9%, individual 68.4 +/- 30.5%, and team 60.6 +/- 30.5%). Boys attained higher heart rates during team activities, while female students had higher rates during individual activities indicating male and female adolescents respond differently to activity types. The highest mean heart rates were observed during fitness activities.  相似文献   

The development of an innovation: the case of porvair     

Michael Gibbons  Dale Littler 《Research Policy》1979,8(1):2-25

Economists and management “scientists” tend to adopt a rationalistic, “black box” approach to the treatment of technological innovation, with decisions to invest in innovation being viewed as climactic acts and with the significant impact of risk and uncertainty often being disregarded. This paper examines an alternative analytical perspective: that a least the early development of technological innovation is a process of incremental decision making where managerial responses are affected by the consequences of previous decisions and by alterations in external information. The development of the “poromeric” Porvair discussed here illustrates the considerable risks that have to be borne when undertaking radical innovation, and the nature of the uncertainties, the interdependency between them and the manner in which they persist, in this case even beyond the commercialization of the new product.  相似文献

Genome-Wide Polygenic Scores Predict Reading Performance Throughout the School Years     

Saskia Selzam  Philip S. Dale  Richard K. Wagner  John C. DeFries  Martin Cederlöf  Paul F. O’Reilly 《Scientific Studies of Reading》2017,21(4):334-349

It is now possible to create individual-specific genetic scores, called genome-wide polygenic scores (GPS). We used a GPS for years of education (EduYears) to predict reading performance assessed at UK National Curriculum Key Stages 1 (age 7), 2 (age 12) and 3 (age 14) and on reading tests administered at ages 7 and 12 in a UK sample of 5,825 unrelated individuals. EduYears GPS accounts for up to 5% of the variance in reading performance at age 14. GPS predictions remained significant after accounting for general cognitive ability and family socioeconomic status. Reading performance of children in the lowest and highest 12.5% of the EduYears GPS distribution differed by a mean growth in reading ability of approximately two school years. It seems certain that polygenic scores will be used to predict strengths and weaknesses in education.  相似文献   

Facial Similarity Mitigates the Persuasive Effects of Source Bias: An Evolutionary Explanation for Kinship and Susceptibility to Influence     

Adam S. Richards  Dale Hample 《Communication monographs》2016,83(1):1-24

This research examined how the interaction between a source's facial similarity to message targets and communicated bias affects audience persuadability. We used an evolutionary explanation to hypothesize that biased sources would elicit less favorable attitudes than unbiased sources for dissimilar sources, but that this difference would be absent for similar sources. Predictions were supported by results from a 2 (facial similarity) × 2 (source bias) experiment, in which an unrecognizable percentage of participants' photographs (n = 94) was digitally morphed with a source's face to act as a kinship cue. Further, structural equation modeling demonstrated a direct effect of facial similarity on attitude independent of mediation by source liking and appraisals, providing further evidence that susceptibility to influence from facially similar sources may have evolutionary origins.  相似文献
