Travel behavior changes and responses to advanced traveler information in prolonged and large-scale network disruptions: A case study of west LRT line construction in the city of Calgary

The objective of this study was the investigation of travel behavioral effects of the reduction in traffic capacity resulting from the construction of the West LRT (Light Rail Transit) line in the city of Calgary, Alberta, Canada. Travelers’ responses to real-time information providing traffic updates and advisory detours due to lane/road closures were also examined. The West LRT alignment extends approximately 8.2 km from downtown into the city’s southwest. Many road closures took place in the vicinity of the LRT line construction zones, inducing significant delays to traffic. Data on travelers’ behavioral responses and responses to real-time information were obtained by conducting a survey on a sample of users of the main road affected by the construction. The survey also investigated the effects of West LRT line construction on drivers’ daily commutes, including increases in travel times, mode choices, alternate route choices, and selection of sources of information on traffic conditions. A significant change in the selection of transportation mode was caused by West LRT construction. Throughout the construction period, there was a decrease in the percentage of respondents who reported private vehicles as their first choice and an increase in the percentage of respondents who preferred public transit as their first and second choices. Radio was found to be the most preferred source for traffic updates and detour advice, followed by variable message signs (VMS). The findings of the en-route information model showed that driving experience, employment status, travel time and purpose, and desire for pre-trip information had significant effects on traveler’s rerouting decisions after getting en-route information through VMS. The results from this study are of interest for understanding behavioral changes for the purposes of traffic management, mitigation schemes and design of advanced traveler information systems in response to network disruptions.     

Longitudinal Changes in Memory Performance and Processing Speed in Old Age abstract Keywords

The speed theory of cognitive aging posits that an age-related slowing of processing speed leads to impairments in higher order cognitive functions, such as memory. However, only few studies have examined the relationship between longitudinal changes in processing speed and longitudinal changes in memory performance. In the present study, data of 474 older adults (T1: 59–65 years) from the Interdisciplinary Longitudinal Study on Adult Development (ILSE) were used to investigate whether changes in speed and in memory were associated over a 4-year period. Performance changes in both constructs were analyzed using latent change factor models. Results show that latent changes in processing speed and latent changes in memory performance correlated with 0.61. This association is considerably lower than what would have been expected from cross-sectional data. Our longitudinal results suggest that although speed changes explain a substantial proportion of variance in memory changes, additional explanatory factors must be taken into consideration.     

Lay Perceptions of Psychotherapists in South Africa

The study investigated South African layperson perceptions of psychotherapists. Participants were 10 males and 25 females (Whites = 23, Blacks = 10, Coloreds = 2; age range 20 to 59). Semi structured interviews were used to study expectations, attitudes and stereotypical beliefs and behavior towards psychotherapists. Laypersons perceived psychotherapists negatively, and would personally not want any assistance from psychotherapists.     

Influencing value priorities and increasing well-being: The effects of reflecting on intrinsic values

A four-week experimental study (N?=?113) examined the effects of reflecting on intrinsic values. In the experimental group, participants learned about the distinction between intrinsic (e.g. having close relationships) and extrinsic (e.g. being popular) values, wrote about two personal intrinsic values, and then reflected on these values weekly for four weeks. In the control group, participants completed parallel exercises related to the daily details of their lives. Results revealed that participants in the intrinsic values group experienced greater well-being immediately following the written reflection than participants in the control group. Four weeks later, the more engaged participants felt in the reflection exercises, the more they prioritized intrinsic over extrinsic values and the greater their well-being. These effects occurred only for participants in the intrinsic values condition. The implications for changing value priorities and improving well-being are discussed.     

Implementing climate equity: the case of Europe

For over two decades, international environmental equity – the fair and just sharing of the burdens associated with environmental changes – has been the subject of much debate by philosophers, activists and diplomats concerned about climate change. It has been manifested in many international environmental agreements, notably the Framework Convention on Climate Change and the Kyoto Protocol. The question arises as to whether it is being put into practice in this context. Are the requirements of international environmental equity merely words and principles in international instruments, or are they having a practical effect on the policies of state governments? This article aims to start answering these questions. It examines whether the European Union (EU) and its member states are sharing the burdens of climate change. The article introduces equity in the context of the climate change agreements and looks at some normative and practical considerations. It suggests that Europe has been a leader on international equity in the climate change negotiations over the last decade, and it points to what European states and the EU have done to take on some of the burdens of climate change. Europe's actions are briefly assessed from practical and normative perspectives. Europe is doing more than any other part of the world to address climate change and to share the burdens associated with it. Nevertheless, Europe is not doing as much to address this problem as it can and should do. Both practical and normative imperatives demand more urgent action by Europe to implement climate equity.     

Introduction: Attaining a New Stage

The current issue of The Journal of Adult Development addresses one of the threads of adult development, namely stage and stage change. There are four major forms of adult developmental study that can be identified: positive adult development, directionless change, stasis, and decline. The first of the four forms, positive adult developmental processes, is divided into at least six areas of study: hierarchical complexity (orders, stages), knowledge, experience, expertise, wisdom, and spirituality. The topic of this special issue, stage and stage change, is therefore part of the study of positive adult developmental processes. Finally, the manner in which these topics are studied both in this special issue and elsewhere can be characterized in terms of three broad classifications (Commons & Bresette, 2000, Commons & Miller, 1998) for the acquisition of knowledge and the verification of truth in general. These classifications include analytic, experiential, and empirical means to reach truth.

A Quality Life in the Shadow of Terrorism

After the demise of the Soviet Union, many individuals felt a sigh of relief as fear was leaving them. Yet, over the years, counselors have seen a new fear—terrorism—demonstrated in drive-by shootings, hate crimes, and now, weapons of mass destruction. In helping clients deal with this all-too-real phenomenon, a reframing process is in order, one that views our lives not in permanence, but as constant change. Much needless suffering is due to clinging to permanent belief systems, which, in reality, are impermanent. Many clients I have worked with have found effective ways not only to deal with, but to flourish in whatever life brings, via a self-Being relationship.     

论庄存与的《公羊》学

庄存与的《公羊》学虽然受到赵《春秋属辞》的影响 ,但主要限于治学体例 ,而在治学立场上 ,二者其实有根本的歧异。庄存与克服了赵以策书之体说《春秋》的倾向 ,并注重《春秋》例辞背后的立场。这点直接上承汉代《公羊》学。不过 ,庄氏《春秋》学在某些具体的事例解释上与汉代《公羊》学也有差异。庄氏的特点在于对《春秋》变辞的引申与发挥 ,并补充了汉代《公羊》学未曾论述的诸多方面 ,为后人理解《公羊》大义提供了新的线索。     

Preconscious defence analysis, memory and structural change

Beginning with the ways in which the use of the couch lends 'depth to the surface' (Erikson, 1954), I explore the topography of the inter - and intra subjective psychoanalytic situation and process. I suggest that defences are not by definition unconscious but rather can be observed operating at conscious and preconscious levels, particularly under these conditions. A focus on preconscious disavowal provides a window on what has become unconscious repression. As a result of eliciting and then verbalising the operation of such defences with regard to anxieties in the here-and-now transference, declarative memories of increasingly specific childhood fantasies and events begin to hold sway over unmanageable procedural remnants from the analysand's past. With this may even come the possibility of neuronal regeneration, the more generalisable enhancement of declarative and symbolic functions and the sense of identity with which these are associated. Herein may lie one enduring therapeutic effect of the 'talking cure' - putting feelings into words - as one among a variety of psychotherapeutic modalities.
