Expected car use reduction in response to structural travel demand management measures

Selecting the appropriate travel demand management (TDM) measures aiming to reduce the environmental problems associated with private transportation demands a thorough understanding of the behavioral consequences of different measures. In this scenario based study, the expected car use reduction in response to one push measure (i.e. raised tax on fossil fuel), one pull measure (i.e. improved public transport), and a combination of the two measures were analyzed. The aim was to compare the expected car use reduction in response to the different TDM measures, the car use reduction strategies used to achieve this reduction, and factors important for the expected car use reduction (i.e. background factors, internal motivational factors (general intention and personal norm), and perceived personal impact of the measure). In a two step between-subject design, a sample of car users first answered a pre-questionnaire and subsequently three groups of car users (N = 274) each evaluated one of the TDM measures. Results demonstrated that the combined measure led to larger expected car use reduction compared to the measures evaluated individually and the reduction was mainly expected to be made by means of trip chaining and changing travel mode. Moreover, internal motivational factors, such as personal norm or general intention, and the perceived impact of the measure, were found to be important for the expected car use reduction in response to the TDM measures.     

Faith, Premarital Sex and Relationships: Are Church Messages in Accordance with the Perceived Realities of the Youth? A Qualitative Study in KwaZulu–Natal, South Africa

Since religious messages on life style have a strong impact in South Africa, it is important to assess how they relate to the situation for young people at risk of HIV infection. Nine focus group discussions were conducted with youth (n = 62), aged 13–20 years, from the Roman Catholic Church, the Lutheran Church, and the Assemblies of God. Young people were ambivalent toward sexual contacts since these generally were expected to be part of a relationship even though the church condemns premarital sex. Girls perceived the moral norms to concern them more than the boys for whom sexual needs were more accepted. These moral barriers lead to lack of information about protection and may increase the risk of HIV. The realities young people facing should be a major concern for the faith communities.     

Freedom – the abyssal ground of Freudian psychoanalysis

Freedom is an a priori condition for the way in which Freudian psychoanalysis thematizes the development, the structure and the dynamics of our psychic life; the human psyche is essentially constituted by freedom. What this really means is that psychoanalysis lacks a foundation or ground – both as a psychological science and as a kind of clinical treatment. Freedom is the abyssal ground of psychoanalysis.     

Perceptions of unfairness in allocations between multiple recipients

This paper introduces a new model to explain perceptions of unfairness in resource allocations between multiple recipients. The model yields several novel predictions, all confirmed in a series of new empirical tests. For instance, while much prior research focuses on the differences between the judge’s share and others’ shares, we argue that people also care about differences between others’ shares. In particular, the presence of a single loser increases perceptions of unfairness. We also study individual variation in sensitivity to the single-loser dimension. Most centrally, we offer empirical support for the existence – indeed the prevalence – of ostraphobics, individuals with an acute sensitivity to being “ostracized” as a sole loser. We show that ostraphobics perceive unfairness more strongly than other types, are higher in need to belong and fear of negative evaluation, and are more prone to a heretofore unrecognized type of preference reversal with respect to fairness.     

Residual differences in language processing in compensated dyslexics revealed in simple word reading tasks

Using regional cerebral blood flow as an index of cerebral activity we studied dyslexic and control subjects during simple word reading tasks. The groups were pre-tested for reading skill and the dyslexic group had a lower reading performance but could read and comprehend standard texts. The aim was to elucidate differences in the cerebral activation pattern during reading. The tasks were simple enough that performance differences between the groups could be excluded. We found specific differences between the two groups that were dependent on the language task. When the visual route for language information was used, minor qualitative differences were found between the groups pertaining to the dominant hemisphere. Increasing the complexity of the task by using pseudowords activated the left frontal region more in the dyslexic group than in the control group. A similar effect was seen in a minor region in extrastriate lateral occipital cortex (BA 19). This finding indicates that the dyslexics used areas in these regions that the controls did not. On the other hand, the dyslexics activated less in the right angular gyrus, right dorsolateral prefrontal cortex, and in the right pallidum. Reading skill correlated with the level of activity in the right frontal cortex. We conclude, that cerebral activation pattern elicited by reading is different in dyslexics compared to controls in spite of an almost complete functional compensation.     

Perception of vocal effort and distance from the speaker on the basis of vowel utterances

The sound pressure level of vowels reflects several nonlinguistic and linguistic factors: distance from the speaker, vocal effort, and vowel quality. Increased vocal effort also involves the emphasis of higher frequency components and increases in F0 and F1. This should allow listeners to distinguish it from decreased distance, which does not have these additional effects. It is shown that listeners succeed in doing so on the basis of single vowels if phonated, but not if whispered, and that they compensate for most of the between-vowel variation in level. The results obtained when listeners had to estimate vocal effort as well as distance suggest that an analysis of an utterance takes place at an early stage in auditory processing, before memories of episodes are stored.     

Communicative development in Swedish children 16-28 months old: the Swedish early communicative development inventory--words and sentences

To describe the development of words and sentences in Swedish children 16-28 months old, 900 parental reports on 336 children were analyzed. Subjects were randomly selected from the national birth register, and there was a response rate of 88%. The assessments were made using the Swedish Early Communicative Development Inventory--words and sentences (SECDI--w&s). Age-based norms for productive vocabulary, pragmatic skills, grammar skills, and maximum length of utterance (MaxLU) were determined. We describe the development of feedback morphemes, semantic categories, and single words and tasks. Correlation across measures was significant, and especially strong between vocabulary size and grammar skills. Optimized positive predictive values were high for 25 to 28 month predictions (71%-88%), and vocabulary scores were found to be of particular predictive importance. No significant gender differences were detected. The clinical relevance of the instrument is discussed.     

Depth motion sensitivity functions

Functions reliably describing perception of motion in depth have been established experimentally by using psychophysical methods of size and distance estimations and threshold measurements. The stimuli were generated with a new hybrid technique yielding an image refresh rate of 1667 Hz. In this way it was possible to generate rapid expansions and contractions of the moving checkerboard pattern constituting the stimulus for depth motion perception. The results showed that perceived size constancy as well as depth impression varied with oscillation frequency. Under the conditions of slow motions (oscillation frequencies around 2 Hz), perfect size constancy was obtained. Above that limit, size constancy systematically decreased, and with oscillation frequencies of about 5 Hz the perceived size constancy was close to zero when small-sized patterns were used. Under the conditions of wide field stimulation (when the pattern subtended 66 degrees of visual angle), the cut-off limit increased to 16 Hz. Since the perception of depth motion amplitudes as well as perceived velocities of the visual object are related to perceived size constancy, the findings have certain implications for theoretical explanations of depth motion perception.

Postmodern society and social networks: open and anticipation dialogues in network meetings

Network therapy flourished in the U.S. during the 1970s, but has since dwindled there and begun to find new applications in Europe, especially in the Nordic countries. State social and healthcare systems, in developing deep vertical expertise, seems to build up a need for complementary horizontal expertise. The latest theories of sociology are used to analyze the need for networking, with the focus on language and dialogue as specific form. Two approaches developed in crisis service for psychotic patients (Open Dialogue) and in consultation for stuck cases in social care (Anticipation Dialogues), are dealt with. What becomes essential seems no longer to be the therapeutic method itself but the ability to see the polyphonic nature of clients' reality. In this respect, language--and dialogue as a specific form of being in language--as the focus of treatment, makes the practical forms of different approaches secondary.
