The principle of least effort within the hierarchy of linguistic preferences: external evidence from English

The thesis is an investigation of the principle of least effort (Zipf 1949 [1972]). The principle is simple (all effort should be least) and universal (it governs the totality of human behavior). Since the principle is also functional, the thesis adopts a functional theory of language as its theoretical framework, i.e. Natural Linguistics. The explanatory system of Natural Linguistics posits that higher principles govern preferences, which, in turn, manifest themselves as concrete, specific processes in a given language. Therefore, the thesis’ aim is to investigate the principle of least effort on the basis of external evidence from English. The investigation falls into the three following strands: the investigation of the principle itself, the investigation of its application in articulatory effort and the investigation of its application in phonological processes. The structure of the thesis reflects the division of its broad aims. The first part of the thesis presents its theoretical background (Chapter One and Chapter Two), the second part of the thesis deals with application of least effort in articulatory effort (Chapter Three and Chapter Four), whereas the third part discusses the principle of least effort in phonological processes (Chapter Five and Chapter Six). Chapter One serves as an introduction, examining various aspects of the principle of least effort such as its history, literature, operation and motivation. It overviews various names which denote least effort, explains the origins of the principle and reviews the literature devoted to the principle of least effort in a chronological order. The chapter also discusses the nature and operation of the principle, providing numerous examples of the principle at work. It emphasizes the universal character of the principle from the linguistic field (low-level phonetic processes and language universals) and the non-linguistic ones (physics, biology, psychology and cognitive sciences), proving that the principle governs human behavior and choices. Chapter Two provides the theoretical background of the thesis in terms of its theoretical framework and discusses the terms used in the thesis’ title, i.e. hierarchy and preference. It justifies the selection of Natural Linguistics as the thesis’ theoretical framework by outlining its major assumptions and demonstrating its explanatory power. As far as the concepts of hierarchy and preference are concerned, the chapter provides their definitions and reviews their various understandings via decision theories and linguistic preference-based theories. Since the thesis investigates the principle of least effort in language and speech, Chapter Three considers the articulatory aspect of effort. It reviews the notion of easy and difficult sounds and discusses the concept of articulatory effort, overviewing its literature as well as various understandings in a chronological fashion. The chapter also presents the concept of articulatory gestures within the framework of Articulatory Phonology. The thesis’ aim is to investigate the principle of least effort on the basis of external evidence, therefore Chapters Four and Six provide evidence in terms of three experiments, text message studies (Chapter Four) and phonological processes in English (Chapter Six). Chapter Four contains evidence for the principle of least effort in articulation on the basis of experiments. It describes the experiments in terms of their predictions and methodology. In particular, it discusses the adopted measure of effort established by means of the effort parameters as well as their status. The statistical methods of the experiments are also clarified. The chapter reports on the results of the experiments, presenting them in a graphical way and discusses their relation to the tested predictions. Chapter Four establishes a hierarchy of speakers’ preferences with reference to articulatory effort (Figures 30, 31). The thesis investigates the principle of least effort in phonological processes, thus Chapter Five is devoted to the discussion of phonological processes in Natural Phonology. The chapter explains the general nature and motivation of processes as well as the development of processes in child language. It also discusses the organization of processes in terms of their typology as well as the order in which processes apply. The chapter characterizes the semantic properties of processes and overviews Luschützky’s (1997) contribution to NP with respect to processes in terms of their typology and incorporation of articulatory gestures in the concept of a process. Chapter Six investigates phonological processes. In particular, it identifies the issues of lenition/fortition definition and process typology by presenting the current approaches to process definitions and their typology. Since the chapter concludes that no coherent definition of lenition/fortition exists, it develops alternative lenition/fortition definitions. The chapter also revises the typology of phonological processes under effort management, which is an extended version of the principle of least effort. Chapter Seven concludes the thesis with a list of the concepts discussed in the thesis, enumerates the proposals made by the thesis in discussing the concepts and presents some questions for future research which have emerged in the course of investigation. The chapter also specifies the extent to which the investigation of the principle of least effort is a meaningful contribution to phonology.

Perceção dos enfermeiros sobre as competências de supervisão clínica

Introdução: A evolução da ciência e tecnologia, as mudanças no seio das organizações de saúde, as novas e emergentes filosofias de cuidados, exigem dos profissionais de saúde uma participação ativa na formação dos seus pares, tendo o processo de supervisão clínica uma importância relevante. Objetivos: Identificar a perceção dos enfermeiros tutores especialistas sobre as competências do supervisor clínico na área de saúde infantil e pediatria. Métodos: Estudo qualitativo exploratório descritivo, fenomenológico, numa amostra de dez enfermeiros tutores dos serviços da área de pediatria do Hospital Dr. Nélio Mendonça, SESARAM. Recorremos à entrevista semiestruturada e áudio gravada. Efetuámos análise de conteúdo ao “corpus” de todas as entrevistas, com definição de subcategorias e indicadores. Resultados:. Emergiu a categoria competências do supervisor clínico e as subcategorias mais referenciadas foram as caraterísticas pessoais com 38% de unidade de registo e as competências profissionais (25,7%). Nos aspetos relevantes em saúde infantil e pediatria destacaram-se também as competências pessoais e profissionais com 40,4% cada. O principal fator facilitador da supervisão foi o ser um processo estruturado (21,6%), e o dificultador foi o deficit no relacionamento interpessoal (21,7%). No global houve mais unidades de registo relacionadas com os aspetos dificultadores. Conclusão: Conscientes das perceções dos supervisores numa área tão específica como é a área de saúde infantil e pediatria, pensamos que este estudo poderá contribuir para melhorar a qualidade do processo supervisivo na enfermagem. É necessário o esforço conjunto entre o supervisor e supervisionado, melhorando os processos mediados entre as instituições e os atores, onde proliferam a partilha de saberes, experiências e objetivos profissionais. Palavras-chave: Supervisor, Mentor, Supervisor clínico, Enfermagem, Supervisão.

Language Outcomes of the Play and Language for Autistic Youngsters (PLAY) Project Home Consultation model—An Extended Analysis

The current study is a post-hoc analysis of data from the original randomized control trial of the Play and Language for Autistic Youngsters (PLAY) Home Consultation program, a parent-mediated, DIR/Floortime based early intervention program for children with ASD (Solomon, Van Egeren, Mahone, Huber, & Zimmerman, 2014). We examined 22 children from the original RCT who received the PLAY program. Children were split into two groups (high and lower functioning) based on the ADOS module administered prior to intervention. Fifteen-minute parent-child video sessions were coded through the use of CHILDES transcription software. Child and maternal language, communicative behaviors, and communicative functions were assessed in the natural language samples both pre- and post-intervention. Results demonstrated significant improvements in both child and maternal behaviors following intervention. There was a significant increase in child verbal and non-verbal initiations and verbal responses in whole group analysis. Total number of utterances, word production, and grammatical complexity all significantly improved when viewed across the whole group of participants; however, lexical growth did not reach significance. Changes in child communicative function were especially noteworthy, and demonstrated a significant increase in social interaction and a significant decrease in non-interactive behaviors. Further, mothers demonstrated an increase in responsiveness to the child’s conversational bids, increased ability to follow the child’s lead, and a decrease in directiveness. When separated for analyses within groups, trends emerged for child and maternal variables, suggesting greater gains in use of communicative function in both high and low groups over changes in linguistic structure. Additional analysis also revealed a significant inverse relationship between maternal responsiveness and child non-interactive behaviors; as mothers became more responsive, children’s non-engagement was decreased. Such changes further suggest that changes in learned skills following PLAY parent training may result in improvements in child social interaction and language abilities.

Structures familiales, encadrement communautaire et survie des enfants. Une recherche en milieu rural malien

The influence of the family environment on child survival is difficult to study using retrospective data, especially in contexts where family structures are complex and where children are mobile. Data from a follow-up survey in rural Mali (1976-2009) are used here to address this question. Several indicators are constructed to test the effect of family structures on child mortality: morphology of the domestic group, availability of family resources, the child's place in the family and the presence of his or her parents. Bivariate and multivariate analyses find no difference in child mortality across different family environments. This finding suggests that the family and social networks still play a powerful role in regulating and managing risks of unequal treatment and care of children

Foster Fathers: their experiences and contributions to fostering

The paper reports some of the findings of an exploratory study which looks at foster fathers’ experiences of fostering and discusses their routes into foster care and their perspectives on their roles and tasks. The study collected quantitative and qualitative data by approaching all foster fathers registered with a single independent fostering agency based in southeast England. They were asked about their personal and professional attributes, and their experiences of and views concerning the role of foster father. The study discusses the foster fathers’ motivation to foster, and argues that what they see as its positives and drawbacks, and how it fits into their own family lives, are all relevant to improving service recruitment, delivery and retention. The study produced some evidence about the distinctive and positive contribution which foster fathers see themselves making to the lives of the children they foster. Further research is needed to refine our knowledge of what this contribution may be. Such knowledge could potentially develop our understanding of the roles of fathers in child development more generally as well as fine-tuning practice in matching what particular placements have to offer to the needs of individual children.

A dimensão preventiva da intervenção precoce : intervenção psicomotora na creche

O presente relatório tem como principal objetivo apresentar a caracterização do estágio realizado na Equipa Móvel de Desenvolvimento Infantil e Intervenção Precoce (EMDIIP) no âmbito da promoção do desenvolvimento infantil de crianças em contexto de creche, ao longo do segundo ano do mestrado em Reabilitação Psicomotora. Toda a intervenção psicomotora foi planeada consoante os resultados das avaliações formais, das observações informais de cada criança e das preocupações e dificuldades enunciadas pela Educadora de Infância da creche tendo sempre em conta as práticas recomendadas da Intervenção Precoce. Para além das sessões de psicomotricidade realizadas em grupo e individualmente, foi desenvolvido um trabalho de formação parental, com o intuito de promover as interações familiares e divulgar informação sobre o desenvolvimento normal das crianças, e um ajustamento do contexto da sala Arco-Íris. A psicomotricidade revelou ser uma ferramenta essencial na promoção do desenvolvimento infantil não só na sua vertente (re)educativa e terapêutica mas também na sua vertente preventiva.

Crianças e jovens em acompanhamento na Comissão de Proteção de Crianças e Jovens Almada

O presente trabalho tem como principal objetivo caraterizar o acompanhamento processual realizado até à aplicação de medida de acolhimento residencial em crianças/jovens com processo de promoção e proteção em Almada. Para tal, através da elaboração de uma grelha de análise, composta por dados sociodemográficos e aspetos referentes à situação de perigo das crianças/jovens, procedeu-se à consulta de 82 processos na CPCJ de Almada. Os resultados obtidos indicam que há uma predominância de rapazes aos quais foi aplicada tal medida, sendo que na totalidade da amostra a maioria iniciou o processo de promoção e proteção em vigor entre os 10 e os 13 anos, seguindo-se a faixa etária entre os 14 e os 17 de idade. Quanto às tipologias de perigo, encontramos a negligência como a mais comum, tendo as situações de perigo sido sinalizadas maioritariamente por familiares próximos. No que diz respeito ao contexto familiar, verificamos que estas crianças/jovens estavam inseridas predominantemente num agregado monoparental feminino, tendencialmente caraterizado por conflitos relacionais e ausência de suporte familiar, factos que constituíram fatores de decisão para aplicação da medida de acolhimento residencial. No que diz respeito ao acompanhamento dos processos, constatamos que a CPCJ de Almada realizou várias diligências envolvendo vários dos intervenientes participantes na situação de perigo em que a criança/jovem se encontrava, assim como cooperações frequentes com as entidades que conhecem a família. Sugere-se, futuramente, o estudo do impacto da aplicação e execução da medida de acolhimento residencial e do consequente processo de institucionalização de tais crianças/jovens.

The development of selective copying: children’s learning from an expert versus their mother

This study tested the prediction that, with age, children should rely less on familiarity and more on expertise in their selective social learning. Experiment 1 (N=50) found that 5- to 6-year-olds copied the technique their mother used to extract a prize from a novel puzzle box, in preference to both a stranger and an established expert. This bias occurred despite children acknowledging the expert model’s superior capability. Experiment 2 (N=50) demonstrated a shift in 7-to 8-year-olds towards copying the expert. Children aged 9- to 10-years did not copy according to a model bias. The findings of a follow-up study (N=30) confirmed that, instead, they prioritized their own – partially flawed – causal understanding of the puzzle box.
