College Students’ Perceptions of and Responses to Academic Dishonesty: An Investigation of Type of Honor Code,Institution Size,and Student–Faculty Ratio

College students (n = 928) from small, medium, and large institutions with either a modified or no honor code were presented with cheating scenarios and asked to rate how dishonest they perceived the behavior to be and the likelihood that they would report it. No main effects were found for institution size or type of honor code. Student–faculty ratio was not correlated with responses to the cheating scenarios. Students from modified honor code schools perceived more severe punishments for cheating and understood the reporting process better than students from non–honor code schools. Implications for modified honor code systems are discussed.     

Depressive symptoms in Friedreich ataxiaSíntomas depresivos en la ataxia de Friedreich

Background/Objective: Almost no attention has been paid to depression in Friedreich ataxia (FRDA), a highly disabling cerebellar degenerative disease. Our aim was to study the presence and the profile of depressive symptoms in FRDA and their relationship with demographic-disease variables and cognitive processing speed. Method: The study groups consisted of 57 patients with a diagnosis of FRDA. The Beck Depression Inventory-II was used to assess symptoms of depression. Speed of information processing was measured with a Choice Reaction time task. Results: The mean BDI score for patients was significantly higher than the mean score in the general population. Twenty one percent of participants scored in the moderate/severe range. A Cognitive-Affective score and a Somatic-Motivational score was calculated for each patient. Patients’ scores in both dimensions were significantly higher than the scores in the general population. Demographic and disease variables were not related with symptoms of depression, except for severity of ataxia. Depressive symptoms predict cognitive reaction times. The greater proportion of variance was explained by the Cognitive-Affective dimension. Conclusions: Our data show that both somatic-motivational and cognitive affective symptoms of depression are frequent in individuals with FRDA. In addition, depressive symptoms may influence cognition, especially, the cognitive and affective symptoms.     

Time course analyses of orthographic and phonological priming effects during word recognition in a transparent orthography

In opaque orthographies, the activation of orthographic and phonological codes follows distinct time courses during visual word recognition. However, it is unclear how orthography and phonology are accessed in more transparent orthographies. Therefore, we conducted time course analyses of masked priming effects in the transparent Dutch orthography. The first study used targets with small phonological differences between phonological and orthographic primes, which are typical in transparent orthographies. Results showed consistent orthographic priming effects, yet phonological priming effects were absent. The second study explicitly manipulated the strength of the phonological difference and revealed that both orthographic and phonological priming effects became identifiable when phonological differences were strong enough. This suggests that, similar to opaque orthographies, strong phonological differences are a prerequisite to separate orthographic and phonological priming effects in transparent orthographies. Orthographic and phonological priming appeared to follow distinct time courses, with orthographic codes being quickly translated into phonological codes and phonology dominating the remainder of the lexical access phase.     

"The W and M are mixing me up": use of a visual code in verbal short-term memory tasks

When normal participants are presented with written verbal short-term memory tasks (e.g., remembering a set of letters for immediate spoken recall) there is evidence to suggest that the information is re-coded into phonological form. This paper presents a single case study of MJK whose reading follows the pattern of phonological dyslexia. In short-term memory tasks MJK does not phonologically re-code written materials but, it is argued, uses a visual code. There are three main lines of evidence for this, (a) MJK tends to substitute visually similar items for one another, (b) her performance is better with visual than auditory stimuli, and (c) she is able to remember numbers (e.g., 8) better than written words (e.g., eight). Investigation of short-term memory in others with phonological dyslexia is warranted.     

Essential ethics — embedding ethics into an engineering curriculum

Ethical decision-making is essential to professionalism in engineering. For that reason, ethics is a required topic in an ABET approved engineering curriculum and it must be a foundational strand that runs throughout the entire curriculum. In this paper the curriculum approach that is under development at the Padnos School of Engineering (PSE) at Grand Valley State University will be described. The design of this program draws heavily from the successful approach used at the service academies — in particular West Point and the United States Naval Academy. As is the case for the service academies, all students are introduced to the “Honor Concept” (which includes an Honor Code) as freshmen. As an element of professionalism the PSE program requires 1500 hours of co-op experience which is normally divided into three semesters of full-time work alternated with academic semesters during the last two years of the program. This offers the faculty an opportunity to teach ethics as a natural aspect of professionalism through the academic requirements for co-op. In addition to required elements throughout the program, the students are offered opportunities to participate in service projects which highlight responsible citizenship. These elements and other parts of the approach will be described.

Idealism or Pragmatism? An Operational Code Analysis of Yitzhak Rabin andShimon Peres

This study quantitatively measured the operational codes of Yitzhak Rabin and Shimon Peres according to the Verbs in Context System (VICS) devised by Walker, Schafer, and Young (1998). Rabin's and Peres's basic propensities regarding the nature and conduct of foreign policy were then compared through analyses of variance, both to each other and across time. Three main trends were found in the results. First, both leaders' conception of their political environment changed over time, from basically conflictual in the 1970s to essentially neutral in the 1990s. Second, the remainder of Rabin's operational code, including a surprisingly strong predisposition to approach politics in a cooperative manner, was generally constant across time. Third, unlike Rabin, several other components of Peres's operational code underwent acute fluctuations, seemingly in response to the perceived different situational context. On the basis of these results and the operational code construct in general, a typology was created that classifies leaders according to their predisposition to pursue either cooperative or conflictual strategies and their level of responsiveness to their political environment.     

Reliability in the context of the experiment: A commentary on two articles by Birkimer and Brown

Two sources of variability must each be considered when examining change in level between two sets of data obtained by human observers; namely, variance within data sets (phases) and variability attributed to each data point (reliability). Birkimer and Brown (1979a, 1979b) have suggested that both chance levels and disagreement bands be considered in examining observer reliability and have made both methods more accessible to researchers. By clarifying and extending Birkimer and Brown's papers, a system is developed using observer agreement to determine the data point variability and thus to check the adequacy of obtained data within the experimental context.     

A graphical judgmental aid which summarizes obtained and chance reliability data and helps assess the believability of experimental effects

Interval by interval reliability has been criticized for "inflating" observer agreement when target behavior rates are very low or very high. Scored interval reliability and its converse, unscored interval reliability, however, vary as target behavior rates vary when observer disagreement rates are constant. These problems, along with the existence of "chance" values of each reliability which also vary as a function of response rate, may cause researchers and consumers difficulty in interpreting observer agreement measures. Because each of these reliabilities essentially compares observer disagreements to a different base, it is suggested that the disagreement rate itself be the first measure of agreement examined, and its magnitude relative to occurrence and to nonoccurrence agreements then be considered. This is easily done via a graphic presentation of the disagreement range as a bandwidth around reported rates of target behavior. Such a graphic presentation summarizes all the information collected during reliability assessments and permits visual determination of each of the three reliabilities. In addition, graphing the "chance" disagreement range around the bandwidth permits easy determination of whether or not true observer agreement has likely been demonstrated. Finally, the limits of the disagreement bandwidth help assess the believability of claimed experimental effects: those leaving no overlap between disagreement ranges are probably believable, others are not.
