When Legitimizing a Request Increases Compliance: The Legitimizing Object Technique

Earlier research reported that using pictures in a fundraising request increases donations by legitimizing the solicitation. The present study tested the effectiveness of a solicitation for money made in the street when an object that legitimated the request was present or not. Male confederates asked passersby for money to buy a stamp while either holding or not holding an envelope in one hand. With a high effect-size, it was reported that the presence of the envelope increased compliance with the request. The legitimation of the request associated with the presence of the envelope is used to explain the results.     

Supervisor Support in the Work Place: Legitimacy and Positive Affectivity

Abstract

The authors tested 3 hypotheses regarding supervisor support in the work place. The validation hypothesis predicts that when employees are supported by their coworkers and the larger organization, they also receive more support from their supervisors. The positive affectivity hypothesis predicts that employees with positive dispositions receive more supervisor support because they are more socially oriented and likable. The moderation hypothesis predicts a joint multiplicative effect between validation and positive affectivity. An assessment of the hypotheses among a sample of 1,882 hospital employees in Korea provided strong support for the validation and moderation hypotheses.     

Evaluation of a preliminary method to examine antecedent and consequent contributions to noncompliance

We evaluated a preliminary method for examining the antecedent and consequent contributions to noncompliance exhibited by two children with disabilities. In Phase 1, we assessed whether noncompliance was a result of a skill deficit. For one participant, we then conducted a functional analysis to determine the variables maintaining noncompliance in Phase 2. In Phase 3, we conducted a treatment evaluation to increase compliance for each participant. We identified the antecedent and consequent variables responsible for noncompliance and developed an effective intervention for both participants.

Applying the extended theory of planned behaviour to predict Chinese people's non‐remunerated blood donation intention and behaviour: The roles of perceived risk and trust in blood collection agencies

Against the backdrop of critical clinical blood shortage in China in recent years, the present research extends the theory of planned behaviour by incorporating two constructs potentially of importance in influencing non‐remunerated blood donation behaviour, namely perceived risk and individual trust in blood collection agencies to predict Chinese people's non‐remunerated blood donation intention and behaviour. A survey was conducted to measure variables of the theory of planned behaviour, and other variables such as experience of non‐remunerated blood donation, perceived risk and individual trust in blood collection agencies. Data to assess non‐remunerated blood donation behaviour were collected via phone interviews. Results of the path analysis are as follows. Subjective norm, perceived behavioural control and individual trust in blood collection agencies are all positively associated with attitudes toward non‐remunerated blood donation, explaining 46.9% of the variance in this variable. Perceived risk is negatively associated with blood donation intention, while subjective norm and attitudes toward non‐remunerated blood donation are both positively associated with blood donation intention. Together, the three variables account for 28.4% of the variance in donation intention. Both having a positive association with non‐remunerated blood donation behaviour, the combination of blood donation intention and donation experience explains 42.8% of its variance.     

对高血压诊治的现象与本质的关系反思——聚焦血压变化与心脑肾血液灌注量的关系

高血压和低血压都存在急性状态和慢性状态,在急性状态,高血压表现为血流高灌注,低血压表现为血流低灌注;而在慢性状态,高血压和低血压则表现出共同的特点——血流低灌注。血压数值只是个表面现象,重要的是透过血压数值的变化去探究血压变化背后的病理生理改变,尤其是血压变化与重要脏器血液灌注量多少的关系,治疗的最终目的是维持人体脏腑器官一定的血流量,而不是仅仅满足于发现并治疗患者所表现出来的血压数值。     

Extensions of the Johnson-Neyman Technique to Linear Models With Curvilinear Effects: Derivations and Analytical Tools

The past decade has witnessed renewed interest in the use of the Johnson-Neyman (J-N) technique for calculating the regions of significance for the simple slope of a focal predictor on an outcome variable across the range of a second, continuous independent variable. Although tools have been developed to apply this technique to probe 2- and 3-way interactions in several types of linear models, this method has not been extended to include quadratic terms or more complicated models involving quadratic terms and interactions. Curvilinear relations of this type are incorporated in several theories in the social sciences. This article extends the J-N method to such linear models along with presenting freely available online tools that implement this technique as well as the traditional pick-a-point approach. Algebraic and graphical representations of the proposed J-N extension are provided. An example is presented to illustrate the use of these tools and the interpretation of findings. Issues of reliability as well as “spurious moderator” effects are discussed along with recommendations for future research.     

情绪和框架效应对个体捐赠决策影响的实验研究

本研究采用双因素被试间实验具体考察了特定即时情绪和框架效应对于捐赠决策的影响,结果发现存在显著的主效应和交互作用。悲伤情绪能够增加捐赠者的捐赠意愿,快乐情绪会降低捐赠者的捐赠意愿;损失框架能够增加捐赠者的捐赠意愿,幸存框架会降低捐赠者的捐赠意愿;快乐情绪的捐赠者的捐赠决策受框架效应的影响要弱于中性情绪和悲伤情绪的捐赠者,捐赠者在幸存框架下的捐赠决策受情绪的影响比在损失框架下受情绪的影响更小。     

Validation of the Multidimensional Blood/Injury Phobia Inventory: Evidence for a Unitary Construct

The Multidimensional Blood/Injury Phobia Inventory (MBPI) was developed from a theoretical framework to characterize a broad range of feared stimuli and phobic reactions associated with this pathology. The MBPI consists of 40 items that cross 4 types of stimulus content (injections, hospitals, blood, injury), 5 types of phobic responses (fear, avoidance, worry, fainting, disgust), and a self versus other focus. This study reports on administration of the MBPI to 558 undergraduates, 9 of whom had blood/injury phobia. The instrument had a Cronbach's alpha of .91 and demonstrated good concurrent validity, convergent validity, and discriminant validity. One large factor emerged in an unrotated principal components analysis, suggesting that blood/injury phobia is a unitary psychometric construct. Exploratory factor analyses revealed a 6-factor solution defined by stimulus content domains and fainting, each of which may be important to consider clinically when assessing the unique concerns of treatment-seeking individuals.     

实验室检验失血与医源性贫血——ICU的潜在危机

所有的住院患者均需采血进行实验室检测,而ICU中的危重患者则更为频繁。有很多原因促使医生开立检验单,以明确疾病的诊断和治疗,但由此而产生的失血却往往易被忽视。病情的危重程度和器官功能障碍程度是检验失血量的主要影响因素,但同时采血技术、检验分析仪性能以及医生开立检验单的目标和规范性等欠佳会增加血液标本的浪费。积极地进行规范的医疗管理和实验室仪器设备的改进等,在满足患者病情治疗需要的前提下尽量降低检验性失血,需要全社会的努力。     

Religion and the decision to donate organs: Exploring the potential role of religious leaders

The two‐step flow model of communication (Katz, 1957 ) suggests opinion leaders obtain critical information from the mass media and, in turn, communicate this information to interpersonal contacts such as friends, family and co‐workers. It is suggested that religious leaders (RLs) may serve as opinion leaders on the topic of organ donation by debunking donation myths, promoting donation during worship services, or communicating the benefit of donation to families faced with the opportunity to participate in living or cadaveric donation. The current study examined the personal knowledge, experiences, and willingness to communicate about organ donation in a sample of RLs (N = 59) in Rochester, New York. Structured interviews were conducted in summer and fall of 2009 with a random sample of RLs. Results indicate a disparity between RLs' expressed personal support for donation and their engagement in donor registration. Approximately one‐quarter of RLs have spoken about donation during a religious service and many indicate their knowledge is not sufficient to discuss organ donation in detail. Results elaborate on how RLs may be trained to serve as opinion leaders in the promotion of organ donation. Copyright © 2010 John Wiley & Sons, Ltd.     

Mental Models: An Alternative Evaluation of a Sensemaking Approach to Ethics Instruction

In spite of the wide variety of approaches to ethics training it is still debatable which approach has the highest potential to enhance professionals' integrity. The current effort assesses a novel curriculum that focuses on metacognitive reasoning strategies researchers use when making sense of day-to-day professional practices that have ethical implications. The evaluated trainings effectiveness was assessed by examining five key sensemaking processes, such as framing, emotion regulation, forecasting, self-reflection, and information integration that experts and novices apply in ethical decision-making. Mental models of trained and untrained graduate students, as well as faculty, working in the field of physical sciences were compared using a think-aloud protocol 6 months following the ethics training. Evaluation and comparison of the mental models of participants provided further validation evidence for sensemaking training. Specifically, it was found that trained students applied metacognitive reasoning strategies learned during training in their ethical decision-making that resulted in complex mental models focused on the objective assessment of the situation. Mental models of faculty and untrained students were externally-driven with a heavy focus on autobiographical processes. The study shows that sensemaking training has a potential to induce shifts in researchers' mental models by making them more cognitively complex via the use of metacognitive reasoning strategies. Furthermore, field experts may benefit from sensemaking training to improve their ethical decision-making framework in highly complex, novel, and ambiguous situations.     

Catching With Both Hands: An Evaluation of Neural Cross-Talk and Coordinative Structure Models of Bimanual Coordination

Kelso, Southard, and Goodman (1979) and Marteniuk and MacKenzie (1980) have each proposed a different theoretical model for bimanual coordination. In the model of Kelso et al., a close temporal relationship between the hands in a bimanual task is predicted, even when each hand is required to move different distances. In Marteniuk and MacKenzie's model, separate motor commands are issued so that each limb will arrive simultaneously at the specified movement endpoint, leading to low temporal associations between limbs. In most previous work on bimanual coordination, manual aiming tasks with differing constraints have been used by subjects in individual studies. In this study, the usefulness of existing models for predicting performance in a real-world catching task in which the required movement pattern was constrained by ball flight characteristics was examined. Eleven university students caught tennis balls with both hands in the following 3 conditions: Condition 1. Ball projected to the right shoulder area (left hand moved a greater distance than the right); Condition 2. Ball projected to center of the chest area, (both hands moved same distance); and Condition 3. Ball projected to left shoulder area (right hand moved a greater distance). Kinematic data (time to peak velocity, movement initiation time) indicating significant cross-correlations between the left and right limbs in all 3 conditions concurred with the data of Kelso et al. (1979) on manual aiming. Timing appeared to be an essential variable coordinating bimanual interceptive actions. Although the limbs moved at different speeds when each was required to move different distances, times to peak velocity showed strong associations, suggesting the presence of a coordinative structure.     

A Priestly Approach to Environmental Theology: Learning to Receive and Give Again the Gifts of Creation

Abstract : A priestly sensibility is here presented as a way to characterize humanity's place in creation. Sacrifice, asceticism, and gratitude are described as three distinct and practical modalities of a priestly life that contribute to the care and celebration of creation. While a priestly understanding is often associated with Orthodox environmental theology, it has the potential to inform environmental theology broadly construed.     

Using a Sharp Instrument to Parse Apart Strategy and Consistency: An Evaluation of PPT and Its Assumptions

Potential Performance Theory (PPT) is a general theory for parsing observed performance into the underlying strategy and the consistency with which it is used. Although empirical research has supported that PPT is useful, it is desirable to have more information about the bias and standard errors of PPT findings. It also is beneficial to know the effects of violations of PPT assumptions. The authors present computer simulations that evaluate bias and standard errors at varying levels of strategy, consistency, and number of trials per participant. The simulations show that, when the assumptions are true, there is very little bias and the standard errors are low when there are moderate or large numbers of trials per participant (e.g., N = 50 or N = 100). But when the independence assumption is violated, PPT provides biased findings, although the bias is quite small unless the violations are large.     

Adherence to antiretroviral therapy for pediatric HIV infection: review of the literature and recommendations for research

This review described and compared empirical investigations of adherence to pediatric antiretroviral therapy (ART) and predictors/correlates of adherence with regard to methodology and outcome. Thirteen empirical studies of children's adherence to ART, conducted between the years 1981 and 2002 were identified. Investigations varied by age of participant, drug therapy regimen, method of adherence assessment, and by the reporting of predictors/correlates of adherence. Conclusions from the literature are limited by the lack of common sample characteristics and adherence assessment methodologies. Nevertheless, consistent with much of the pediatric adherence literature, adherence to antiretroviral medications among children and adolescents appears to be frequently suboptimal. Few investigations identified predictors/correlates of adherence, but these appear generally similar to those found in adult samples. Recommendations for future investigations are proposed.     

The Link: An Alternative Educational Program in the Netherlands to Reengage School-Refusing Adolescents With Schooling

Facets of school life affect the development and maintenance of school refusal (SR). These facets will warrant attention during intervention for SR. This paper considers a range of school-related factors associated with SR, grouped according to five domains of school climate. It also describes school-based interventions for SR in the form of alternative educational programs (AEPs). The paper then presents the Link, an AEP for Dutch adolescents with SR. The Link offers an educational setting that addresses school-related factors associated with SR. After participation in the Link, adolescents are helped to return to a more typical educational setting. Based on a review of 30 case files, we provide an account of adolescents who have participated in the Link. Often, these adolescents displayed chronic and severe SR, met criteria for anxiety or depressive disorders, and were diagnosed with an autism spectrum disorder. The Link process is illustrated via a case vignette. Thereafter, the role of AEPs in the treatment of SR is discussed.     

Experience With a Linguistic Variant Affects the Acquisition of Its Sociolinguistic Meaning: An Alien-Language-Learning Experiment

How do speakers learn the social meaning of different linguistic variants, and what factors influence how likely a particular social–linguistic association is to be learned? It has been argued that the social meaning of more salient variants should be learned faster, and that learners' pre-existing experience of a variant will influence its salience. In this paper, we report two artificial-language-learning experiments investigating this. Each experiment involved two language-learning stages followed by a test. The first stage introduced the artificial language and trained participants in it, while the second stage added a simple social context using images of cartoon aliens. The first learning stage was intended to establish participants' experience with the artificial language in general and with the distribution of linguistic variants in particular. The second stage, in which linguistic stimuli were accompanied by images of particular aliens, was intended to simulate the acquisition of linguistic variants in a social context. In our first experiment, we manipulated whether a particular linguistic variant, associated with one species of alien in the second learning phase, had been encountered in the first learning phase. In the second experiment, we manipulated whether the variant had been encountered in the same grammatical context. In both cases we predicted that the unexpectedness of a new variant or a new grammatical context for an old variant would increase the variant's salience and facilitate the learning of its social meaning. This is what we found, although in the second experiment, the effect was driven by better learners. Our results suggest that unexpectedness increases the salience of variants and makes their social distribution easier to learn, deepening our understanding of the role of individual language experience in the acquisition of sociolinguistic meaning.
