Abstract. In a repeated-measures experimental study, we examined how evidence type influences police investigators’ beliefs about (a) suspect’s culpability and (b) reliability of incriminating evidence. South Korean detectives ( N = 202) read four crime reports including general information about a crime and a suspect. In the general case information, one piece of critical and several pieces of noncritical evidence collected during the investigation were presented. Officers read four simulated reports of crimes, and in each report, they were given one piece of evidence linking the suspect to the crime. We manipulated the critical evidence identifying the suspect with four evidence types: CCTV, DNA, fingerprint, and eyewitness testimony. We found that evidence type influenced detectives’ judgments about suspect’s culpability and evidence reliability, such that when eyewitness (vs. CCTV, DNA, fingerprint) evidence was given as critical evidence, officers were more likely to think that the suspect was less culpable and that the evidence was less reliable. Theoretical and legal implications of these results are discussed.

The Impact

This experimental study sought to examine the impact of four indicators of active learning (i.e., elaborated feedback, group work, situated learning, and videos and pictures in classroom instruction) on the enhancement of Saudi students’ various motivational constructs (i.e., self-efficacy, task value, and effort expenditure) and English achievement. Participants were 289 university students, and the data were collected at three time points: Time 1 (before the intervention), Time 2 (in the middle of the intervention), and Time 3 (after the intervention). The findings of repeated measures ANOVA and follow-up t-tests revealed that the intervention had small impacts on all the variables at Time 2 (in the middle of the intervention). However, at Time 3 (after the intervention), the intervention had small impacts on effort expenditure and task value, a moderate impact on academic achievement, and a large impact on self-efficacy. In general, the evidence obtained provides important implications for educational practices and further research development.

Moderating Role

PurposeThis paper aims to investigate the impact of different types of corporate social responsibility (CSR; i.e. value-creating CSR, promotional CSR and philanthropic CSR) on consumer responses and the moderating role of corporate competence.Design/methodology/approachThe authors tested the hypotheses by using two empirical studies – a survey and an experimental study. The evidence is generated based on generalized linear model repeated-measures ANOVAs for the survey study and two-way factorial ANOVAs for the experimental study.FindingsThe findings show that in general, consumers respond to value-creating CSR more favorably than to philanthropic CSR or promotional CSR. In addition, corporate competence moderates consumers’ responses to different types of CSR in such a way that promotional CSR is more likely to have the desired effects when carried out by low-competency rather than by high-competency firms, whereas value-creating CSR is more effective for high-competency firms than for low-competency ones. Philanthropic CSR works equally in both types of firms.Research limitations/implicationsThis research answers a long-term call to study the differential consumer effects of various CSR types. It also identifies perceived corporate competence, an important consumer-based corporate factor, as a potential moderator of consumers’ response to CSR types.Practical implicationsArmed with the findings, companies can choose CSR practices that fit with their company characteristics. This research offers important and specific managerial implications to firms with different company profiles on their CSR choices.Originality/valueGiven that today’s managers are faced with the challenge of selecting desirable CSR activities from a group of options, the authors answered the call by studying the differential effects of a wide array of CSR choices and provide important practical guidance to managers. For the first time in the literature, the study also investigates the potential interactive effects between specific CSR types and corporate competence on consumer reactions. This inquiry bears significant relevance to the ongoing discussions concerning whether and how company characteristics generate influences on the outcomes of CSR strategies.

The Impact

Purpose: Fitness testing is common within physical education, but there has been considerable debate about the pedagogical purpose and potential psychological implications of this practice. The aim of this study was to conduct a pilot experimental study to determine the impact of traditional fitness testing approaches on the body image, self-esteem, mood, and attitudes toward fitness testing of a sample of Australian students. Method: Fifty-one students in Grades 7–10 completed a questionnaire before and after their usual two traditional fitness testing classes at their school. Results: Repeated-measures analysis of variance revealed there were no significant differences from T1 to T2 on body image, self-esteem, or mood scores. However, there were significant differences observed over time, for participants aged over 15 years, whose self-esteem, social self-esteem subscale, and attitudes toward fitness testing scores, decreased from T1 to T2. Conclusion: This study provides initial evidence that older students may experience a decline in self-esteem due to fitness testing.

The goal of the present study is to investigate whether the comprehension of oligosemic, i.e. culturally-specific (CS) idioms is raised with awareness of underlying conceptual metaphors (CMs) as seems to be the case with idioms motivated by metaphors (CM idioms). An experimental study was conducted involving the metaphor-aware Experimental group and the Control group which was unaware of the existence of CMs. Metaphoric awareness was achieved through brief 15 minute-long lessons on metaphor and underlying motivation. The Control participants were given general information on figurative language in order to ensure equality of input. The instrument containing 35 items was administered to both groups whereas the Experimental group was also provided the underlying CM motivation. An ANOVA test for repeated measures was used to compare CM data to CS data. There was a statistically significant effect of motivation on idiom comprehension, F(1,77)=67.203, p=.000 which suggests that CM idioms are better understood than CS idioms. The t-test results for the CS idioms indicate there is a significant difference between the Control and the Experimental group when it comes to the comprehension of CS idioms in favor of the Experimental participants; it seems the comprehension of CS idioms is raised with metaphoric awareness.

Exchanger Tube

The current study experimentally investigates the heat transfer augmentation on the novel axial corrugated heat exchanger tube in which the spring tape is introduced. Air (Pr = 0.707) is used as a working fluid. In order to augment the thermohydraulic performance, a corrugated tube with inserts is offered. The experimental study is further extended by varying the important parameters like spring ratio (y = 1.5, 2.0, 2.5) and Reynolds number (Re = 10 000–52 000). The angular pitch between the two neighboring corrugations and the angle of the corrugation is kept constant through the experiments at β = 1200 and α = 600 respectively, while two different corrugations heights (h) are analyzed. While increasing the corrugation height and decreasing the spring ratio, the impact of the swirling effect improves the thermal performance of the system. The maximum thermal performance is obtained when the corrugation height is h = 0.2 and spring ratio y = 1.5. Eventually, correlations for predicting friction factor (f) and Nusselt number (Nu) are developed.

Objective: This study examined the influence of physicians’ recommendations and gender on the decision-making process in a preference-sensitive situation. Methods: N = 201 participants were put in a hypothetical scenario in which they suffered from a rupture of the anterior cruciate ligament (ACL). They received general information on two equally successful treatment options for this injury (surgery vs. physiotherapy) and answered questions regarding their treatment preference, certainty and satisfaction regarding their decision, and attitude toward the treatment options. Then participants watched a video that differed regarding physician’s recommendation (surgery vs. physiotherapy) and physician’s gender (female vs. male voice and picture). Afterward, they indicated again their treatment preference, certainty, satisfaction, and attitude, as well as the physician’s professional and social competence.Results: Participants changed their treatment preferences in the direction of the physician’s recommendation (P<.001). Decision certainty (P<.001) and satisfaction (P<.001) increased more strongly if the physician’s recommendation was congruent with the participant’s prior attitude than if the recommendation was contrary to the participant’s prior attitude. Finally, participants’ attitudes toward the recommended treatment became more positive (surgery recommendation: P<.001; physiotherapy recommendation: P<.001). We found no influence of the physician’s gender on participants’ decisions, attitudes, or competence assessments.Conclusion: This research indicates that physicians should be careful with recommendations when aiming for shared decisions, as they might influence patients even if the patients have been made aware that they should take their personal preferences into account. This could be particularly problematic if the recommendation is not in line with the patient’s preferences.
