AbstractFor many years, both academia and industry have been interested in increasing the efficiency of idea- generation meetings. Alex Osborne's (1953) rules for brainstorming are an early attempt to do so, and have extensively been used in engineering design, however their effectiveness has been questioned with recent research, and a need for fundamental research to establish which practices are useful arises. This study is an attempt in investigating linguistic abstraction in idea-generation meetings, in order to establish whether any best practices can be distilled from the language used. Engineering design group meetings were recorded and transcribed, and was analysed using a coding framework which was developed for analysing linguistic categories as well as the ideas that were generated during those meetings. More particularly, the study investigates the average abstractness/concreteness of speech throughout the duration of the meetings, as well as the switching between abstract and concrete language and vice versa while comparing idea-related discourse and non-idea related discourse switching. The coding framework proposed is considered robust enough to carry out further work.

Distributed leadership as a new scenario of educational leadership has become a popular topic in the contemporary world. Many notable researchers and members of the discourse community have contributed significantly to its development. However, little attention has paid to its effectiveness. Hence, the main purpose of this article is to analyze the existing evidence for the effect of principal’s leadership practice on students’ academic achievement from a distributed perspective. To do so, a systematic search of academic databases was conducted and 68 references spanning from the year 2001 to 2018 were selected and systematically reviewed. Due consideration was given to their concepts of distributed leadership practice, principal’s role, and students’ academic achievement. The findings of this article show that distributed leadership has positive and indirect effect on students’ academic achievement and the role of principal is indispensable. Nevertheless, there is little emperical evidence, a lack of universal accepted patterns and best practices of distributed leadership which strains further investigation. On the basis of evidence currently available, it seems reasonable to recommend scholars, policy developers, and practitioners to recognize the role of principal on distributed leadership and its best practices.

The Impact

Interacting with example products is an essential and widely practiced method in engineering design, yet little information exists on how the representation (pictorial or physical) or interaction a designer has with an example impacts design creativity. This is problematic because without this knowledge we do not understand how examples affect idea generation or how we can effectively modify or develop design methods to support example usage practices. In this paper, we report the results of a controlled study with first year engineering design students (N = 89) developed to investigate the impact of a designer's interaction with either a two-dimensional (2D) pictorial image or a three-dimensional (3D) product (through visual inspection or product dissection activities) and the resulting functional focus and creativity of the ideas developed. The results of this study reveal that participants who interacted with the physical example produced ideas that were less novel and less functionally focused than those who interacted with the 2D representation. Additionally, the results showed that participants who dissected the product produced a higher variety of ideas than those that visually inspected it. These results contribute to our understanding of the benefits and role of 2D and 3D designer-product interactions during idea development. We use these findings to develop recommendations for the use of designer-product interactions throughout the design process.

Engineering idea generation plays a vital role in the development of novel products. Prior studies have shown that designers fixate to the features of example solutions and replicate these features in their ideas. This type of fixation acts as a major hindrance in idea generation, as it restricts the solution space where designers search for their ideas. Building upon the study by Linsey et al. [2010, “A Study of Design Fixation, Its Mitigation and Perception in Engineering Design Faculty,” ASME Trans. J. Mech. Des., 132, 041003], this study hypothesizes that designers fixate to example features and this fixation can be mitigated using certain defixation materials including alternate representations of the design problem. To investigate this, the experiment conducted by Linsey et al. [2010] with engineering design faculty is replicated with novice designers. Participants generate ideas for a design problem in three groups: one group working with a fixating example, a second group working with the same example along with alternate representations of the design problem and a control group. The obtained results show that both the novice designers and design faculty fixate to the same extent, whereas the defixation materials have differential effect on the two groups. This result indicates that design researchers need to be very careful in developing methods and guidelines that are formulated and tested with studies on novice designers. The effectiveness of such measures may vary with the level of expertise of the designer.

SummaryThe role of intravascular coagulation in the production of the generalized Shwartzman phenomenon has been evaluated. The administration of endotoxin to animals prepared with Thorotrast results in activation of the coagulation mechanism with the resultant deposition of fibrinoid material in the renal glomeruli. Anticoagulation prevents alterations in the state of the coagulation system and inhibits development of the renal lesions. Platelets are not primarily involved. Platelet antiserum produces similar lesions in animals prepared with Thorotrast, but appears to do so in a manner which does not significantly involve intravascular coagulation.The production of adrenal cortical hemorrhage, comparable to that seen in the Waterhouse-Friderichsen syndrome, following the administration of endotoxin to animals that had previously received ACTH does not require intravascular coagulation and may not be a manifestation of the generalized Shwartzman phenomenon.

By decentring our reading of Hamlet, Stoppard’s tragicomedy questions the legitimacy of centres and of stable frames of reference. So Liliane Campos examines how Stoppard plays with the physical and cosmological models he finds in Hamlet, particularly those of the wheel and the compass, and gives a new scientific depth to the fear that time is ‘out of joint’. In both his play and his own film adaptation, Stoppard’s rewriting gives a 20th-century twist to these metaphors, through references to relativity, indeterminacy, and the role of the observer. When they refer to the uncontrollable wheels of their fate, his characters no longer describe the destruction of order, but uncertainty about which order is at work, whether heliocentric or geocentric, random or tragic. When they express their loss of bearings, they do so through the thought experiments of modern physics, from Galilean relativity to quantum uncertainty, drawing our attention to shifting frames of reference. Much like Schrödinger’s cat, Stoppard’s Rosencrantz and Guildenstern are both dead and alive. As we observe their predicament, Campos argues, we are placed in the paradoxical position of the observer in 20th-century physics, and constantly reminded that our time-specific relation to the canon inevitably determines our interpretation.

One might assume that the desire to help (here described as Want) is the essential driver of helping declarations and/or behaviors. However, even if desire to help is low, helping behavior may still occur if the expectancy regarding the perceived effectiveness of helping is high. We tested these predictions in a set of three experimental studies. In all three, we measured the desire to help (Want) and the Expectancy that the aid would be impactful for the victim; in addition, we manipulated Expectancy in Study 3. In Studies 1 and 3, we measured the participants’ declaration to help while in Study 2, their helping behavior was examined. In all three studies, we used variations of the same story about a victim. The results supported our hypothesis. Thus, the studies help to tease apart the determinants of helping behavior under conditions of lowered desire to do so, an issue of great importance in public policymaking.

Interest in wisdom in the cognitive sciences, psychology, and education has been paralleled by conceptual confusions about its nature and assessment. To clarify these issues and promote consensus in the field, wisdom researchers met in Toronto in July of 2019, resolving disputes through discussion. Guided by a survey of scientists who study wisdom-related constructs, we established a common wisdom model, observing that empirical approaches to wisdom converge on the morally-grounded application of metacognition to reasoning and problem-solving. After outlining the function of relevant metacognitive and moral processes, we critically evaluate existing empirical approaches to measurement and offer recommendations for best practices. In the subsequent sections, we use the common wisdom model to selectively review evidence about the role of individual differences for development and manifestation of wisdom, approaches to wisdom development and training, as well as cultural, subcultural, and social-contextual differences. We conclude by discussing wisdom’s conceptual overlap with a host of other constructs and outline unresolved conceptual and methodological challenges.

Based on analysis of two case studies in the Canton of Bern, this article examines the question of knowledge transfer from history to transport policy and planning in the recent past in Switzerland. It shows that for several reasons, direct knowledge transfer did not occur. In particular, historians have seldom become actively involved in transport planning and policy discourses, probably partly because the academic system offers no incentive to do so. However, historical knowledge has certainly influenced decision-making processes indirectly, via personal reflection of the actors in the world of practice or through Switzerland's strongly developed modes of political participation. Because the potential for knowledge transfer to contribute to better policy solutions has not been fully utilized, we recommend strengthening the role of existing interfaces between science and policy.

Tis paper aims to describe the syntax of the constructions that present the verbal extensions {-ik-} and {-uk-} and their allomorphs in Shimakonde, a Bantu language classifed as P23 in the Guthrie classifcation (GUTHRIE 1967-71). Tis language is spoken in the northern regions of Mozambique and Tanzania. Tese verbal extensions are reported in literature under the labels of stative, impositive, pseudo-passive, neuter, and quasi-passive (DOKE, 1947; SATYO, 1985; MCHOMBO, 1993; DUBINSKY SIMANGO, 1996; BENTLEY KULEMEKA, 2001; LIPHOLA, 2001; NGUNGA, 2004; KHUMALO, 2009; LEACH, 2010; LANGA, 2013). Te addition of the {-ik-} or {-uk-} morphemes to the verb structure usually demotes or suppresses the external argument, turning a basically transitive predicate into an intransitive one. Tis paper aims to investigate in Shimakonde if alternations from a dyadic to a monadic predicate, through the use of one of the aforementioned morphemes, are instances of the phenomenon known in literature as causative/ anticausative alternation (HASPELMATH, 1987, 1993; LEVIN RAPPAPORT HOVAV, 1992, 1995; NAVES, 1998, 2005; VAN HOUT, 2004; OLIVEIRA, 2011; KALLULLI, 2007). In order to do so, I analyze the grammatical role of this morpheme with two Shimakonde native consultants from different Mozambique districts (Mocimboa da Praia and Montepuez). Te feldwork activities consisted of translations of sentences from Portuguese to Shimakonde, testing the grammaticality of the proposed sentences. In order to examine the data that were collected, I adopted the Alexiadou, Anagnostopoulou and Schäfer (2006) refnement of the verbal categories by Levin Rappaport Hovav (1992, 1995). One of the results obtained is that the verbal extensions display an atelic reading (giving rise to stative interpretation) or a telic reading (giving rise to anticausative or passive interpretation). To account for the different interpretations in these constructions, I propose distinct associations between Asp head and Voice head in accordance with Kratzer (1996), Pylkkänen (2002), van Hout (2004), and Oliveira (2010).

This chapter examines the role of the judiciary with regard to the Convention on the Rights of Persons with Disabilities (CRPD). It considers the relationship which the judiciary have or appear to perceive themselves as having with the CRPD and explores some of the factors seemingly prompting courts to refer to it. The first section reflects on: whether judges are able to choose to refer to the Convention or have a legal duty to do so; the significance of the fact that the CRPD is international law; and whether judges appear to see themselves merely as domestic actors, or as agents or trustees of the CRPD. The second section explores whether judges are referring to the CRPD in response to arguments raised before the court or doing so of their own volition. Also considered are the relevance of amicus curiae interventions; reasons for referral related to the domestic legal system; and the role of particularly engaged individuals.
