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.     

Integration of motion parallax with binocular disparity specifying different surface shapes

We investigated the interaction between motion parallax and binocular disparity cues in the perception of surface shape and depth magnitude by the use of the random dot stimuli in which these cues specified sinusoidal depth surfaces undulating with different spatial frequencies. When ambiguous motion parallax is inconsistent with unambiguous disparity cue, the reasonable solution for the visual system is to convert the motion signal to the flow on the surface specified by disparity. Two experiments, however, found that the visual system did not always use this reasonable solution; observers often perceived the surface specified by a composite of the two cues, or the surface specified by parallax alone. In the perception of this composite of the two cues, the apparent depth magnitude increased with the increase of the depth magnitude specified by both cues. This indicates that the visual system can combine the depth magnitude information from parallax and disparity in an additive fashion. The interference with parallax by disparity implies that the parallax processing is not independent of the disparity processing.     

儒家伦理思想与当代中国道德体系建设

儒家伦理思想作为中华民族道德传统的主干,一直深深地、普遍地影响着人们的思想观念和行为选择,对中华民族的道德追求、行为方式和人格塑造都产生了重大影响。儒家“仁爱”的道德原则及其道德规范体系,以及关于职业道德、家庭道德和社会公德的思想和要求,都是社会主义道德建设的宝贵资源。我们应当坚持批判继承其原则和方法,摒弃其消极因素,吸取、弘扬其积极因素,这对于当今中国道德体系的建设是十分重要的。     

Science and Religion: Getting Ready for the Future

I explore three challenges for the current dialogue between science and religion: the challenges from hermeneutics, feminisms, and postmodernisms. Hermeneutics, defined as the practice and theory of interpretation and understanding, not only deals with questions of interpreting texts and data but also examines the role and use of language in religion and in science, but it should not stop there. Results of the post‐Kuhnian discussion are used to exemplify a wider range of hermeneutical issues, such as the ideological potential of scientific concepts, the dynamics of interdisciplinarity, and the significance of the socioeconomic situatedness of science and religion. Feminist research analyzes the consequences of the interplay of masculine, feminine, and gender typologies in religion and science. Examples from the history of science as well as current scientific conceptualizations indicate that beliefs in the inferiority of woman form part of our inherited scientific, religious, and metaphysical framework. It is argued that postmodernism in its most constructive form shares the best fruits of modernity, especially of the Enlightenment, while avoiding some of its most serious mistakes. In conclusion, reflecting on the three publics engaged in the dialogue between science and religion—academe, religious communities, and societies—I offer constructive suggestions and critical observations concerning the future of this dialogue.     

How To Engage With Experimental Practices? Moderate Versus Radical Constructivism

A central question in constructivist studies of science is how the analyst should deal with the material objects handled by scientific practitioners in laboratories. Representatives of ‘radical constructivism’ such as Knorr-Cetina and Latour have gone furthest in exploring the role of these ‘non-humans’ but have also maneuvered themselves in untenable positions due to a fatal conflation of different meanings of the term ‘construction’. The epistemological and ontological commitments of ‘moderate constructivism’ especially of the Strong Program defended by Barnes and Bloor, are more suitable for dealing with the task at hand. While radical constructivists treat the domains of nature and human society as largely coterminous, an alternative ontology stresses that natural reality is never fully absorbed into the world of culture but only interacts with the latter at localizable interfaces such as practices and artifacts. This perspective promises a more relaxed relationship with current forms of scientific realism. This revised version was published online in August 2006 with corrections to the Cover Date.

Exploring changes during life and career design dialogues

This article describes the processes of change that occur during career counseling based on the ‘making oneself self’ model (Guichard, 2008; Guichard, 2009). This counseling intervention process forms part of the more general paradigm of life designing (Savickas et al., 2009). The main goal for this counseling is fostering “reflexivity” of individuals with regard to their investment in their various spheres of life. Three career counseling interviews were conducted using both methods of dialogues for life and career design dialogues (LCDD) and self-confrontation (Larsen, Flesaker, & Foundation, 2008; Valach, Michel, Dey, & Young, 2002). Each interview is described with a focus on the changes perceived by the interviewees in relation to their initial reason for consulting as well as on their dialogues with the counselor, who facilitated these changes and provided support for them. The analysis of the dialogues suggests the existence of a three-step evolution supporting the changes. On the basis of these data, the discussion examines the reflexive approach in its theoretical, methodological and practical dimensions.     

The influence of satisfaction and promotability on the relation between career adaptability and turnover intentions

This study examined the relation between career adaptability (CA), promotability, and career satisfaction (CS), and their impacts on turnover intentions (TI). Eight hypotheses were proposed. Based on data collected from a sample of 431 employees in Macau, career adaptability was significantly and positively related to both promotability and CS after controlling for the influences of demographic variables including age, gender, education and tenure. CA, promotability and CS were also significantly and negatively linked to TI. The results further revealed that promotability and CS mediated the effect of CA on TI. The study contributed new insights that may inform career development and retention of employees. Practical implications on how to retain employees were discussed.     

Symposium Introduction: Reflexivity in Life Designing Interventions

This article introduces the Symposium on Reflexivity in Life Design Interventions. Eight articles report studies of counseling processes and client operations during life design interventions as well as client feedback during subsequent Interpersonal Process Recall interviews. The Symposium concludes with comments on and discussion of the studies.     

Reflection and reflexivity during life-design interventions: Comments on Career Construction Counseling

The 8 articles in the Symposium advanced understanding of “Reflexivity in Life-Design Interventions”. This discussion highlights distinctions between reflection and reflexivity, as well as their relation to first-order and second-order change. Then the contributions of the Symposium authors are organized using four phases of narrative counseling: symbolic representation, reflective self-examination, reflexive new realizations, and revisioning career identity. The discussion concludes by organizing the diverse terms the authors used to name these four phases into a uniform format.
