Direct Outcome

The subject of liquid crystals is a fascinating one. The involvements of the subject, representing, some would say, a ‘fourth state of matter’, range from the highly theoretical to the highly technical, and its investigators in both academic and industrial institutions belong to disciplines as distinct as chemistry, physics, electrical and electronic engineering, applied physics, and biology. The strong tempo of research in the subject today is of course a direct outcome of the technological applications of liquid crystals in electro-optical display devices and temperature-sensing devices. Successes in these areas have, however, arisen only through the closest of collaborations among research and industrial scientists from such different disciplines. After a suitable introduction, progress to date in the area of applications will be traced, with emphasis upon the critical role of interdisciplinary collaboration. Given its continuation in the face of growing competition, some techno­logical prospects for the future will be examined.

Over Time

In this article, we contribute to a processual understanding of knowledge integration in interdisciplinary collaboration by foregrounding the role of dialogue in dealing with epistemic uncertainty. Drawing on an ethnographic study of collaboration among scientists involved in developing a highly novel bioreactor, we suggest that knowledge integration is not a homogeneous process but requires switching between different knowledge integration practices over time. This is particularly notable in the case of ‘epistemic breakdowns’ – deeply unsettling events where hitherto-held understandings of the nature of problems appear unworkable. In such cases, it is not sufficient to deal solely with coordination issues; collaborators need to find ways to address generative knowledge integration processes and to venture, collectively, into the unknown. We demonstrate how this generative quest of knowledge integration is achieved through a dialogical process of drawing and testing new distinctions that allows actors to gradually handle the epistemic uncertainty they face.

The Relationship

This contribution towards the subject is limited to three of its aspects—namely, the possible aetiological role of inherited predisposition and psychogenic factors (mainly environmental to which the patient is still exposed), the relationship between late endogenous depression and the symptoms of cerebrovascular changes, and prognosis. On the face of it, prognosis of course must ultimately depend on that of the cerebrovascular disorder but apparently hereditary and environmental factors play a more significant role. Inherited predisposition is here assessed in terms of constitutional and personality factors.

The success of a business in the face of competition is inextricably linked to the ability of a transformational leader to foster a climate of creativity in the workplace. This study presents the findings of an analysis of the role of transformational leaders in fostering a climate of creativity in organizations. Multiple regression analysis is used to analyze data collected from respondents who are randomly selected from employees at several companies and then processed using the SmartPLS application. The researcher developed an instrument for the variables transformational leadership and climate of creativity based on several instruments used in previous research. The findings indicate that there is a strong correlation between transformational leadership and a climate of creativity, implying that transformational leadership plays a critical role in fostering creativity in the workplace.

Media Event

This contribution relates recent theoretizations of media events with the emotion theory in order to get a better picture of what role emotions play in these events. Critical view toward media events helps to understand the limitations of the claims made by those who established this concept 30 years ago: Rather than instances magically integrating society, media events are seen as struggles over the meaning in the contested media field where by far not every winning meaning enhances societal integration. Additionally, psychology and sociology of emotion gives a necessary foundation for the concise theory of emotions in the media events and guides the empirical inquiry into the subject by suggesting that research should focus on the arousing rhetoric as well as narratives interpreting this arousal and turning it into the specific emotion. The analyzed media event – political scandal – very well exemplifies the theoretical argument made in regard to media events, demonstrates the power of emotions in establishing particular versions of reality and illustrates what I call the recursive logic of media events: the fact that their meaning is established at the very end of their occurrence, whereas their event-ness is implied at the beginning with the intensive arousal attracting everyone's attention.

How do faces with social-cultural identity affect bilingual language control? We approach this question by looking at the switch cost patterns and reversed language dominance effect, which are suggested to reflect bilingual language control mechanisms, in the absence (i.e., baseline context) or presence of faces with socio-cultural identity (Asian or Caucasian). In separate blocks, the face matched (i.e., congruent context) or mismatched (i.e., incongruent context) the language to be spoken. In addition, cue preparation time was manipulated to be long (Experiment 1) or short (Experiment 2). In both experiments, a unique asymmetric switch cost with larger costs for L2 was observed in the congruent context as compared with the baseline and incongruent contexts. Furthermore, the reversed language dominance effect was not modulated across contexts. These results suggest a critical role of contextual faces in modulating local but not global language control. Thus, bilingual language control changes flexibly within an environment that includes faces with socio-cultural identity.

Memory Constraints

The role of prediction during sentence comprehension is widely acknowledged to be very critical in SOV languages. Robust clause-fi?nal verbal prediction and its maintenance have been invoked to explain eff?ects such as anti-locality and lack of structural forgetting. At the same time, there is evidence that these languages avoid increased preverbal phrase complexity due to working-memory constraints. Given the critical role of prediction in processing of SOV languages, in this work, we study verbal predictions in Hindi (an SOV language) to investigate its robustness and fallibility using a series of completion studies. Analyses of verbal completions based on grammaticality (grammatical vs ungrammatical) as well as their syntactic property (in terms of verb class) show, as expected, frequent grammatical completions based on effective use of preverbal nouns and case-markers. However, there were also high instances of ungrammatical completions. In particular, consistent errors were made in conditions with 3 animate nouns with unique/similar case-markers. These errors increased in the face of adjuncts of di?ffering complexity following the preverbal nouns. The grammatical and ungrammatical completions show that native speakers of Hindi posit structures with at most 2 verbal heads and 5 core verbal relations, thus highlighting an upper bound to verbal prediction and its maintenance in such con?figurations. A rating study con?firmed that certain errors found in completion tasks can lead to grammatical illusions. Further, a detailed analysis of the completion errors in such cases revealed that the parser ignores the complete preverbal nominal features of the input and instead selectively reconstructs the input based on their frequency in the language to form illicit parses at the expense of globally consistent parses. Together, the results show that while preverbal cues are eff?ectively employed by the parser to make clause ?final structural predictions, the parsing system breaks down when the number of predicted verbs/relations exceeds beyond a certain threshold. In effect, the results suggests that processing in SOV languages is susceptible to center-embeddings similar to that in SVO languages. This highlights the over-arching influence of working-memory constraints during sentence comprehension and thereby on the parser to posit less complex structures.

Group 5

To any observer of Pakistani society and economy over the last 40 years four questions pose themselves with repeated persistence year after year, survey after survey, census after census, decade after decade. They are: the proportion aged less than 15 years of age, the reported age group 5-9, the masculinity ratio, female illiteracy and innumeracy. There are two other features of the Pakistani data situation that ought to be taken into account during any consideration of these data and their collection. They are: the innocence of vital registration systems, and the ineffectiveness of family planning programmes. The first four questions received little attention through the backstopping offered by international agencies, from the subject-matter units in the Federal Bureau of St.atistics (PBS), and from the analysts in such research institutions as the PIDE. There seems to be no awareness of the critical role of women's literacy and numeracy in the reorganization plans of the Ministry of Women's Development [MWD (1989, 1989a)]. The relevant concerns in WD publications are modest [e.g., WD (1980)]. The last two questions

The range of validity of two models for nonlocal nonlinear optics in Nematic Liquid Crystals (NLC) is studied. Particularly the influence of the optical power and the initial position of the beam over its trajectory is studied when launching the beam with an offset in a planar cell. The main difference between both models is the dependence of the orientational angle with the optical field, either linear or nonlinear. The results demonstrate the critical role of the nonlinearity in the propagation of nematicons in NLC planar cells.
