Las estrategias de inserción internacional de los Gobiernos Regionales frente a los acuerdos de integración económica: estudio de caso Nuevo León – TLCAN 2003-2009

La internacionalización de los Gobiernos Locales o las regiones es un fenómeno que día a día está tomando una dimensión y magnitud mayor a nivel internacional. Han sido la globalización, la descentralización y la participación en acuerdos de integración económica los incentivos que impulsan a las regiones a buscar un status y un espacio de participación internacional en temas económicos, ambientales, culturales y de cooperación. En ese sentido la motivación de este Estudio de Caso es analizar el proceso a través del cual Nuevo León logró impulsar la internacionalización de su territorio en el periodo 2003-2009 a partir de la entrada en vigencia del Tratado de Libre Comercio de América del Norte.

Lean construction: Arenas of enactment, models of diffusion and the meaning of 'leanness'

The existing literature on lean construction is overwhelmingly prescriptive with little recognition of the social and politicised nature of the diffusion process. The prevailing production-engineering perspective too often assumes that organizations are unitary entities where all parties strive for the common goal of 'improved performance'. An alternative perspective is developed that considers the diffusion of lean construction across contested pluralistic arenas. Different actors mobilize different storylines to suit their own localized political agendas. Multiple storylines of lean construction continuously compete for attention with other management fashions. The conceptualization and enactment of lean construction therefore differs across contexts, often taking on different manifestations from those envisaged. However, such localized enactments of lean construction are patterned and conditioned by pre-existing social and economic structures over which individual managers have limited influence. Taking a broader view, 'leanness' can be conceptualized in terms of a quest for structural flexibility involving restructuring, downsizing and outsourcing. From this perspective, the UK construction industry can be seen to have embarked upon leaner ways of working in the mid-1970s, long before the terminology of lean thinking came into vogue. Semi-structured interviews with construction sector policy-makers provide empirical support for the view that lean construction is a multifaceted concept that defies universal definition.

Letterforms for handwriting and reading: print script and sanserifs in early twentieth-century England

This essay is about letterforms and typography in reading books for young children and how they were influenced by the teaching of handwriting in the early decades of the twentieth century. I examine the contributions made by infant teachers to typography and book design and draw particular attention to the print script movement and the gradual introduction of sanserif typefaces in reading books. I suggest that the use of sanserifs in reading books for young children is one of their first appearances for continuous text. Although the influence of print script on the teaching of handwriting may have had some undesirable effects, I suggest that it indirectly contributed to some innovations in book design.

The effects of age, enactment, and cue-action relatedness on memory for intentions in the Virtual Week task

The current study investigated the influence of encoding modality and cue-action relatedness on prospective memory (PM) performance in young and older adults using a modified version of the Virtual Week task. Participants encoded regular and irregular intentions either verbally or by physically performing the action during encoding. For half of the intentions there was a close semantic relation between the retrieval cue and the intended action, while for the remaining intentions the cue and action were semantically unrelated. For irregular tasks, both age groups showed superior PM for related intentions compared to unrelated intentions in both encoding conditions. While older adults retrieved fewer irregular intentions than young adults after verbal encoding, there was no age difference following enactment. Possible mechanisms of enactment and relatedness effects are discussed in the context of current theories of event-based PM.

Is prospective memory enhanced by cue-action semantic relatedness and enactment at encoding?

Benefits and costs on prospective memory performance, of enactment at encoding and a semantic association between a cue-action word pair, were investigated in two experiments. Findings revealed superior performance for both younger and older adults following enactment, in contrast to verbal encoding, and when cue-action semantic relatedness was high. Although younger adults outperformed older adults, age did not moderate benefits of cue-action relatedness or enactment. Findings from a second experiment revealed that the inclusion of an instruction to perform a prospective memory task led to increments in response latency to items from the ongoing activity in which that task was embedded, relative to latencies when the ongoing task only was performed. However, this task interference ‘cost’ did not differ as a function of either cue-action relatedness or enactment. We argue that the high number of cue-action pairs employed here influenced meta-cognitive consciousness, hence determining attention allocation, in all experimental conditions.

Adobe Bickham Script Greek typeface

Design support for typeface design: collaborative work commissioned by Adobe, Inc. Published 2011. The original Bickham typeface was based on the hands of the 18th century writing master George Bickham. The ornate script represented the apogee of the art of formal writing with a steel nib, and defined the visual style for decorated, formal documents. In 2010 Adobe revised and extended the typeface, with the express purpose of making it a showcase for OpenType technology, demonstrating the visual importance of using different glyph forms in different contexts, employing contextual substitution rules. Although Bickham had published a single example of a Greek style, it was a standalone exercise, never intended to match the Latin. The key challenge was to identify historical records for appropriate Greek writing, preferably by writers familiar with the language, adapt them for digital typography and the particularities of contextual substitution, in a manner that would not make the Greek a ‘second-class citizen’. Research involved uncovering and analysing appropriate contemporary and later writing examples to identify both the range of writing styles of the period, and the manner of joining letters in written Greek with both pointed pens and broad nibs. This work was essential to make up for the comparative lack of relevant material by Bickham, as well as investigating the possible range of stylistic variants that were approved for the final typeface, which attempted to emulate a written texture through complex substitutions. This aspect of the work is highly original for implementing a substantial number of contextual alternates and ligatures. These were reviewed in the context of use, bringing together an analysis of occurring letter combinations and patterns, and the design of stylistic alternates to imitate natural handwriting.

New wine into old skins: the enactment of literacy policy in Singapore

To better comprehend how educational reforms and classroom practice interconnect, we need to understand the epistemic environments created for learning, as well as the pedagogical activities and the modes of classroom discourse related to these activities. This article examines how a particular innovation in English literacy, Strategies for English Language Learning and Reading (STELLAR), has been implemented in Singapore. Outlining the broader curriculum initiatives, current literacy policy landscape and pedagogical effect of classroom discourse, we look at how English language teachers in grades 1 and 2 interpret the STELLAR curriculum. Situated within the larger international zeal of educational reform, Singapore presents a rich case for the study of policy–pedagogy initiatives, literacy instruction and cultural values. Adding to the existing policy enactment research, this investigation provides an opportunity to probe both the prospects and limitations of policy implementation associated with centralised educational structures, examination-oriented systems and societal cultural frameworks.

Sticking to the script? The co-production of Neighbourhood Planning in England

Efforts to engage with communities in spatial planning have been criticised as being tokenistic, vehicles for co-option or designed to promote neo-liberal agendas. The introduction of neighbourhood planning (NP) in England under the Localism Act (2011) is claimed by proponents to be a step change in the way that local communities are involved in planning their own areas. However, little empirical evidence has yet emerged to substantiate such claims, or provide details about the practices and experiences of NP. The paper highlights that there are numerous parties involved in the co-production of Neighbourhood Development Plans and there are numerous instances where ideas, policies and priorities that emerge from within neighbourhoods are being ‘rescripted’ to ensure conformity to a bounded form of collaboration.

Enhancing prospective memory in mild cognitive impairment: the role of enactment

Prospective memory (PM) is a fundamental requirement for independent living which might be prematurely compromised in the neurodegenerative process, namely in mild cognitive impairment (MCI), a typical prodromal Alzheimer's disease (AD) phase. Most encoding manipulations that typically enhance learning in healthy adults are of minimal benefit to AD patients. However, there is some indication that these can display a recall advantage when encoding is accompanied by the physical enactment of the material. The aim of this study was to explore the potential benefits of enactment at encoding and cue-action relatedness on memory for intentions in MCI patients and healthy controls using a behavioral PM experimental paradigm. Method: We report findings examining the influence of enactment at encoding for PM performance in MCI patients and education-matched controls using a laboratory-based PM task with a factorial independent design. Results: PM performance was consistently superior when physical enactment was used at encoding and when target-action pairs were strongly associated. Importantly, these beneficial effects were cumulative and observable across both a healthy and a cognitively impaired lifespan as well as evident in the perceived subjective difficulty in performing the task. Conclusions: The identified beneficial effects of enacted encoding and semantic relatedness have unveiled the potential contribution of this encoding technique to optimize attentional demands through an adaptive allocation of resources strategies. We discuss our findings with respect to their potential impact on developing strategies to improve PM in AD sufferers.

Instrumentalização do Propagar MOO com ferramentas de planejamento do uso da água e de análise da simulação através da utilização da linguagem Pascal Script

A simulação é uma das ferramentas mais utilizadas para a aplicação da análise sistêmica nos mais diversos estudos. Ao longo do tempo, vários modelos foram desenvolvidos para representar sistemas de recursos hídricos, utilizando a simulação. Dentre esses modelos, está o Propagar MOO, que simula a propagação de vazões em uma bacia hidrográfica, submetida à decisões operacionais de suprimento de demandas e de operação de reservatórios, introduzidas pelo usuário através de rotinas escritas na linguagem de programação Pascal Script. A utilização eficiente dessas rotinas permite ao usuário ampliar a capacidade e flexibilidade do modelo na representação de um sistema hídrico. Com o objetivo de contribuir na ampliação da flexibilidade do modelo Propagar MOO e de sua aplicabilidade à modelagem de sistemas de recursos hídricos em geral, bem como facilitar o estudo da linguagem de programação Pascal Script e motivar os profissionais da área no desenvolvimento de novas rotinas aplicadas ao modelo, foram implementadas, através do presente trabalho, rotinas genéricas contendo estratégias de planejamento do uso da água e de operação de reservatórios, bem como ferramentas para analisar seus resultados. Para ampliar essa contribuição, foi aprimorada a possibilidade de simulação da geração de energia hidrelétrica em pontos de uma rede hidrográfica, com a criação de novas ferramentas para esse fim, na estrutura interna do modelo. Por fim, para que o próprio usuário pudesse construir ferramentas para auxiliar na verificação dos resultados obtidos nas simulações, esse estudo apresenta a implementação de rotinas de uso geral para servir como exemplos de ferramentas de análise de dados.
