Manner of Obtainment as a relative in a family of resultative constructions

The present paper examines the syntactic and semantic properties of a group of constructions which carry an idiomatic interpretation of obtainment. In Polish and German, the constructions under consideration consist of a verb with a directional particle followed by an object NP, as exemplified in (1a)-(1b). (1a) Adam wynurkował starego buta. (Polish) Adam wy- snorkeled old shoe. ‘Adam found an old shoe while snorkeling.’ (1b) Michael erboxte sich den Titel. (German) Michael er- boxed REFL the title. ‘Michael boxed his way to the (championship) title.’ Sentences containing these constructions will be assumed to have the same basic interpretation “Subject obtains/produces Object by V-ing”. A constructional analysis of the constructions will be proposed, as they pose licensing problems and their interpretation cannot be accounted for in terms of the individual conceptual structures of the lexical items composing the sentence. Unlike most accounts of verb particle constructions based on implicit or explicit assumptions of straightforward semantic composition, the present study proposes an analysis under which the semantic structure of verb particle combinations is not a compositional function of the verb and the particle/prefix alone. It is argued that the construction comes with its own subcategorization frame (separate from that carried by the verb) which is motivated by the meaning of the construction and its corresponding constructional subevent. Additionally, a crosslinguistic correlation will be shown to hold between a language’s ability to express event conflation (Talmy 1985, 2000) and the occurrence of some form of the construction in that language. This will be taken as an indication of the resultative nature of those types of directional phrases which involve the semantic interpretation of boundary crossing.

The role of microcomputer-based laboratory display in supporting the construction of new understanding in kinematics

Teachers' failure to utilise MBL activities more widely may be due to not recognising their capacity to transform the nature of laboratory activities to be more consistent with contemporary constructivist theories of learning. This research aimed to increase understanding of how MBL activities specifically designed to be consistent with a constructivist theory of learning support or constrain student construction of understanding. The first author conducted the research with his Year 11 physics class of 29 students. Dyads completed nine tasks relating to kinematics using a Predict-Observe-Explain format. Data sources included video and audio recordings of students and teacher during four 70-minute sessions, students' display graphs and written notes, semi-structured student interviews, and the teacher's journal. The study identifies the actors and describes the patterns of interactions in the MBL. Analysis of students' discourse and actions identified many instances where students' initial understanding of kinematics were mediated in multiple ways. Students invented numerous techniques for manipulating data in the service of their emerging understanding. The findings are presented as eight assertions. Recommendations are made for developing pedagogical strategies incorporating MBL activities which will likely catalyse student construction of understanding.

Skill development for innovative procurement environments in construction

The construction industry should be a priority to all governments because it impacts economically and socially on all citizens. Sector turnover in industrialised economies typically averages 8-12% of GDP. Further, construction is critical to economic growth. Recent Australian studies estimate that a 10% gain in efficiency in construction translates to a 2.5% increase in GDP Inefficiencies in the Australian construction industry have been identified by a number of recent studies modelling the building process. They have identified potential savings in time of between 25% and 40% by reducing non-value added steps in the process. A culture of reform is now emerging in the industry – one in which alternate forms of project delivery are being trialed. Government and industry have identified Alliance Contracting as a means to increase efficiency in the construction industry as part of a new innovative procurement environment. Alliance contracting requires parties to form relationships and work cooperatively to provide a more complete service. This is a significant cultural change for the construction industry, with its well-known adversarial record in traditional contracting. Alliance contracts offer enormous potential benefits, but the Australian construction industry needs to develop new skills to effectively participate in the new relationship environment. This paper describes a collaborative project identifying skill needs for clients and construction professionals to more effectively participate in an increasingly sophisticated international procurement environment. The aim of identifying these skill needs is to assist industry, government, and skill developers to prepare the Australian construction workforce for the future. The collaborating Australian team has been fortunate to secure the Australian National Museum in Canberra as its live case study. The Acton Peninsula Development is the first major building development in the world awarded on the basis of a joint alliance contract.
