Treatment of chronic global aphasia with a nonverbal communication system

Four chronic global aphasics were treated with Blissymbols (C. K. Bliss, 1965, Semantography-Blissymbolics, Sydney: Semantography Pub.). As soon as possible the therapeutic communication was based solely on the use of the symbols. Three patients seemed to benefit from therapy. In one case therapy had to be discontinued because of massive perseveration. In one patient expression of needs relied solely on the use of the symbols. In another, expressive speech could be restored to such an extent that communication by the use of symbols was discontinued.     

Integrating velocity,time, and distance information: A developmental study

The development of understanding the relationships between velocity, time, and distance was investigated in three tasks. In each task, values of two dimensions were given, and 5-year-olds, 10-year-olds, and adults had to infer values of the third dimension. These inferences were made in all age groups. The integration rules were found to depend upon age and task. In the distance = time × velocity task, all age groups obeyed the normative multiplication rule. In the time = distance ÷ velocity task, the two older age groups obeyed the normative division rule, but the 5-year-olds shifted to a simpler subtraction rule. In the velocity = distance ÷ time task, which was the most difficult, the two older age groups simplified to use of a subtraction rule, and the 5-year-olds simplified even further to use of a distance-only rule. The knowledge level revealed for young children contrasts sharply with results from previous studies using Piagetian choice tasks, which apparently investigate selective attention to one dimension rather than conceptual understanding of relations.     

Postdecisional preference for decision-relevant information as a function of the competence of its source and the degree of familiarity with this information

Three experiments are reported concerning the determinants of postdecisional preferences for decision-relevant information. Two factors were considered: the competence of the source of the information and the degree of prior familiarity with the contents of the information. The first two experiments showed that the competence of the source of decision-supporting information affected the desirability of reading both types of information, whereas the competence of the source of decision-opposing information had very little effect on the desirability of reading either type. In the third experiment, the effects of giving subjects access to prior information supporting or opposing their view on their preferences for further information were investigated under conditions in which the number of choices of this later information were either limited or unlimited. The effects of prior information on choices of decision-supporting information were identical regardless of whether the total amount of information available was limited or unlimited: Less decision-supporting information was chosen when subjects had previously been exposed to decision-supporting information than when they had not, and this difference was greater when they had not previously been exposed to decision-opposing information. However, the choices of decision-opposing information under unlimited choice conditions increased with the amount of decision-supporting information previously read, but decreased with the amount of decision-opposing information previously read. The processes that underlie the choices of information under conditions in which several types are available are discussed.     

A characterization of stochastic independence by association,with an application to random utility theory

A characterization of stochastic independence in terms of association of random variables is given. The result is applied to yield a simple proof of the Sattath-Tversky inequality without continuity assumptions.     

Lesions of the basal ganglia, thalamus, and deep white matter: Differential effects on language functions

Forty-five patients with unilateral demarcated vascular lesions in the basal ganglia, the thalamus and the deep white matter were investigated with an "aphasia battery." Patients with basal ganglia lesions performed worse than both other groups in tests of articulation, syntax, and lexical functions. The deficit of patients with basal ganglia lesions on all expressive language modalities was lateralized to the left hemisphere. Patients with left thalamic lesions showed impairments of speech fluency and in the Token Test. Patients with white matter lesions alone showed no effect of laterality in tests of language functions. The results are discussed on the basis of a recent theory of the participation of the deep nuclei in language processing.     

WAYS OF DISCOURSE AND WAYS OF LIFE

In book X of the Republic, Plato famously reports “a quarrel between poetry and philosophy.” The present essay examines this quarrel in book X, along with other relevant parts of the Republic, by understanding “philosophy” and “poetry” as rival ways of life and rival ways of discourse. The essay first explains why, in Plato’s view, poetic discourse weakens one’s power to reason and is at odds with philosophic discourse. Then it shows how poetic discourse is bound up with a way of life that champions the value of freedom. Such a life forms a contrast with the philosophic life, which is marked more by stability and unity than by freedom. The quarrel, however, is not a simple antagonism. The essay hence concludes by discussing why, despite the opposition between the two, philosophy cannot do without poetry.     

Perceived ethical leadership: Its moderating influence on employees’ organisational commitment and organisational citizenship behaviours

This study investigated the extent to which employees’ perception of ethical leadership moderated their organisational commitment and organisational citizenship behaviour. A non-probability purposive sample (N = 839; females = 32%) of employees in a railway organisation in the Democratic Republic of Congo (DRC) participated in the study. They completed the following measures: the Organisational Commitment Scale (OCS), the Organisational Citizenship Behaviour Questionnaire (OCBQ) and the Ethical Leadership Scale (ELS). Stepwise hierarchical regression analysis was utilised to determine the influence of employees’ perceptions of the relationships between their self-reported organisational commitment and organisational citizenship behaviour. The results indicated employee perceptions of the integrity, fairness and honesty aspects of ethical leadership to explain their affective, continuance and normative aspects of organisational commitment and organisational citizenship behaviour. The results also showed that employee perceptions of high ethical leadership influenced their willingness to engage in positive organisational commitment such as psychological attachment, work continuance, normative commitment and also their organisational citizen behaviours such as altruism, conscientiousness, courtesy and civic virtue. By implication, leaders with high ethical conduct have the potential to positively stimulate the commitment of employees towards supporting the organisational values and mission.     

Workplace ethics culture and work engagement: The mediating effect of ethical leadership in a developing world context

This study examined the mediating effect of ethical leadership on the relationship between workplace ethics culture and work engagement among employees in a railway transport organisation in the Democratic Republic of the Congo (DRC). The sample consisted of permanently employed staff in a railway organisation in the DRC (n = 839; females = 32%). The employees were required to complete the Ethical Leadership Scale (ELS), the Ethical Corporate Virtue model (ECV) and the Utrecht Work Engagement Scale (UWES). Mediating regression analyses were conducted to predict work engagement from workplace ethics culture, partialling out ethical leadership. The results show that workplace ethics culture had a significantly positive effect on work engagement. The results further indicated that workplace ethics culture, through the mediation of perceived ethical leadership, had a significantly positive effect on the work engagement dimensions of vigour, dedication and absorption. The findings provide evidence that ethical leadership plays a crucial role in shaping workplace ethics culture and employees’ level of work engagement in an emerging country work setting.     

Sociocultural Predictors of Physical Appearance Concerns among Adolescent Girls and Young Women from China

This research assessed the extent to which sociocultural predictors of body dissatisfaction implicated in Western studies extend to the prediction of physical appearance concerns among young women and adolescent girls in Southwest China. In Study 1, 408 Chinese university-age women completed measures of fatness concern (FC), facial appearance concerns (FAC), sociocultural influence (i.e., appearance pressure, comparison, teasing), and demographics. In hierarchical regression analyses, appearance pressure and comparison predicted both FC and FAC, independent of other factors. In Study 2, effects of appearance pressure and comparison were replicated among middle school (n = 346) and high school (n = 563) girls. Together, findings suggest that appearance pressure and social comparison correspond with specific body image concerns of young females in China.     

Forensic psychology in the Czech republic

The article discusses the field of Forensic Psychology in Czech Republic. It concentrates upon the successes and stagnations of the field, which can be attributed to the political and historical development of the country. After a brief historical background and demographic information, the article introduces the history and structure of the police force and prison service. The article then moves on to discuss the history and publication development of the field of Forensic Psychology and its use in practice. It characterizes the field from its beginnings between the two wars, to the activities of the Research Institute of Penology from 1967 to1980 and the years following the political change of 1989. The article concludes with the law framework within which the field operates. Based upon this summary of the situation in Czech republic, the author makes an assessment of the status of Forensic Psychology in Czech republic, especially in terms of conducting research for the practice.
