AbstractThe paper argues that syntax is motivated by the need to avoid combinatorial search in parsing and semantic ambiguity in interpretation. It reports on a case study for the emergence and sharing of first-order phrase structures in a population of agents playing language games. First-order phrase structures combine words into phrases but do not yet generalise to hierarchical or recursive phrases. To study why human languages exhibit phrase structure, a series of strategies for creating and sharing linguistic conventions are examined, starting from a lexical strategy without syntax and then studying the use of groups, n-grams and patterns. Each time we show in which way a strategy improves on the computational complexity of the previous on.

This paper discusses on the rules of Noun Phrase (NP) in Mandailing language. The objectives are firstly to structurally examine the phrase structure rules (PSR) of NP in Mandailing language and to investigate the constituents of each rules in NP. The method is descriptive qualitative with a case study. The data taken from the native speakers of Mandailing language through interviewing. The data are the utterances of Mandailing language in daily conversation. The analysis is based on the use of X-Bar theory, to see how NPs in Mandailing language are hierarchically governed and presented in tree diagram. Thus, the findings showed that there are five major rules of NP in Mandailing language, (a) single noun as headword, (b) pre-modifier preceedes head noun, (c) post-modifiers follows head noun, (d) head noun between pre-modifier and post-modifier, and (e) complex NP with coordinative conjunction. Also, there is found particle na to relate NP with the complement such as AP. To summarize, Mandailing language has similar patterns of word order with Indonesia language. Overall, this research gives contribution to provide a deep understanding in studying morphosyntactic in linguistics especially phrase structures beyond the effort on exploring and revitalizing a regional language in Indonesia.

The 1960S

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
