DEMOGRAFÍA AMBIENTAL: ¿CÓMO EXPLICAR EL CRECIMIENTO POBLACIONAL A PARTIR DEL ENFOQUE DE LAS FUERZAS MEDIADORAS?

El interés por comprender e interpretar los vínculos entre población y ambiente se constituyó internacionalmente en materia pública a partir de los años sesenta, cuando la posición ambientalista reconoce la necesidad de analizar la presión ejercida por las poblaciones humanas sobre el medio natural. Este campo de estudio se vuelve considerablemente  más complejo en la década de 1990, sobresaliendo las discusiones que en torno a dicha problemática plantearon las conferencias internacionales de población y ambiente. El presente estudio analiza el enfoque de las fuerzas mediadoras como perspectiva a partir de la cual se ha abordado la relación entre la dinámica demográfica y ambiental para explicar que el crecimiento poblacional per se no es la causa primera, ni el impacto más importante de la degradación ambiental. ABSTRACT Interest in understanding and interpreting the relationship between population and environment became an international public concern at the beginning of the 1960’s when  environmentalists recognized the need to analyze the pressure human population puts on  the environment. This field turned into a more complex study area in the ‘90’s decade, mostly because of the increase in discussions around the environmental and population problematic. The aim of this research is to analyze the meditational forces as trigger perspectives, from which the demography dynamics and environmentalist relationship have been understood. This perspective suggests that population growth per se is neither the primary cause nor the most important aspect of environmental degradation.

PROBLEMATIZATION OF REZEPTION STUDIES ON THE SEMIOLINGUISTIK THEORIE

Over the past decades the Discourse Analysis (DA) has attempted to solve articulation problems between the psycho-sociological dimensions of the subjects involved in the language act and the linguistic dimensions that characterize this act. Likewise, it has been a systematic challenge for Humanities to establish a conceptual link between the plans of actor and the psychosocial framework that encompasses it. The results of this endeavour have revealed, however, that the psycho-sociological dimension had been underexploited in DA, since the individuals involved in this instance (Communicating Subject and Interpreting Subject) are abstract and imagined constructs based on their recovered identities, purposes in the act of communication and socially consolidated practices.

Addressing bullying and cyberbullying in schools: Translating theory into practice

Overviews of research are clear that bullying occurs in every school, and that there are significant negative physical and mental health outcomes associated with it (Beaty and Alexeyev, 2008; Carter, 2011). As such, it is imperative to develop successful intervention strategies to help students cope with bullying, including the emergent form of cyberbullying. Research suggests, however, that students have a very limited repertoire of strategies for dealing with bullying generally (Owens, Shute, and Slee, 2004). In this paper the authors outline what is currently known about bullying, including cyberbullying, its impact on students, how theory can assist in developing interventions to assist and support students to cope with bullying, and some of the implications for schools.

Translating vision research into policy and practice to improve visibility, and hence safety, of road workers at night

This case study report describes the stages involved in the translation of research on night-time visibility into standards for the safety clothing worn by roadworkers. Vision research demonstrates that when lights are placed on the moveable joints of the body and the person moves in a dark setting, the phenomenon known as “biological motion or biomotion” occurs, enabling rapid and accurate recognition of the human form although only the lights can be seen. QUT was successful in gaining funding from the Australian Research Council for a Linkage grant due to the support of the predecessors of the Queensland Department of Transport and Main Roads (TMR) to research the biomotion effect in on-road settings using materials that feature in roadworker clothing. Although positive results were gained, the process of translating the research results into policy, practices and standards relied strongly on the supportive efforts of TMR staff engaged in the review and promulgation of national standards. The ultimate result was the incorporation of biomotion marking into AS/NZS 4602.1 2011. The experiences gained in this case provide insights into the processes involved in translating research into practice.

The naturally imperfect form : investigations of the application of digital sculpting methods - extracted art : incorporating and translating ‘found art’ into the medium of digital sculpture

This dissertation analyses how physical objects are translated into digital artworks using techniques which can lead to ‘imperfections’ in the resulting digital artwork that are typically removed to arrive at a ‘perfect’ final representation. The dissertation discusses the adaptation of existing techniques into an artistic workflow that acknowledges and incorporates the imperfections of translation into the final pieces. It presents an exploration of the relationship between physical and digital artefacts and the processes used to move between the two. The work explores the 'craft' of digital sculpting and the technology used in producing what the artist terms ‘a naturally imperfect form’, incorporating knowledge of traditional sculpture, an understanding of anatomy and an interest in the study of bones (Osteology). The outcomes of the research are presented as a series of digital sculptural works, exhibited as a collection of curiosities in multiple mediums, including interactive game spaces, augmented reality (AR), rapid prototype prints (RP) and video displays.

Translating vision research into policy and practice to improve the visibility, and hence safety, or road workers at night

The process of translating research into policy and practice is not well understood. This paper uses a case study approach to interpret an example of translation with respect to theoretical approaches identified in the literature. The case study concerns research into “biological motion” or “biomotion”: when lights are placed on the moveable joints of the body and the person moves in a dark setting, there is immediate and accurate recognition of the human form although only the lights can be seen. QUT was successful in gaining Australian Research Council funding with the support of the predecessors of the Queensland Department of Transport and Main Roads (TMR) to research the biomotion effect in road worker clothing using reflective tape rather than lights, and this resulted in the incorporation of biomotion marking into AS/NZS 4602.1 2011. The most promising approach to understanding the success of this translation, SWOV’s “knowledge utilisation approach” provided some insights but was more descriptive than predictive and provided “necessary but not sufficient” conditions for translation. In particular, the supportive efforts of TMR staff engaged in the review and promulgation of national standards were critical in this case. A model of the conclusions is presented. The experiences gained in this case should provide insights into the processes involved in effectively translating research into practice.

Theatre, social media and spectatorship : translating commentary, critique and controversy across media

The occasional ArtsHub article asking spectators to show respect for stage by switching all devices off notwithstanding, in the last few years we have witnessed an clear push to make more use of social media as a means by which spectators might respond to a performance across most theatre companies. Mainstage companies, as well as contemporary companies are asking us to turn on, tune in and tweet our impressions of a show to them, to each other, and to the masses – sometimes during the show, sometimes after the show, and sometimes without having seen the show. In this paper, I investigate the relationship between theatre, spectatorship and social media, tracing the transition from print platforms in which expert critics were responsible for determining audience response to today’s online platforms in which everybody is responsible for debating responses. Is the tendency to invite spectators to comment via social media before, during, or after a show the advance in audience engagement, entertainment and empowerment many hail it to be? Is it a return to a more democratised past in which theatres were active, interactive and at times downright rowdy, and the word of the published critic had yet to take over from the word of the average punter? Is it delivering distinctive shifts in theatre and theatrical meaning making? Or is it simply a good way to get spectators to write about a work they are no longer watching? An advance in the marketing of the work rather than an advance in the active, interactive aesthetic of the work? In this paper, I consider what the performance of spectatorship on social media tells us about theatre, spectatorship and meaning-making. I use initial findings about the distinctive dramaturgies, conflicts and powerplays that characterise debates about performance and performance culture on social media to reflect on the potentially productive relationship between theatre, social media, spectatorship, and meaning making. I suggest that the distinctive patterns of engagement displayed on social media platforms – including, in many cases, remediation rather than translation, adaptation or transformation of prior engagement practices – have a lot to tell us about how spectators and spectator groups negotiate for the power to provide the dominant interpretation of a work.

The use of headings and marginal notes in interpreting Queensland legislation : appearances can be deceptive

This article considers the rules relating to the use of marginal notes and headings in interpreting Queensland legislation, both in its original form and in reprinted legislation. It also examines the application of the principles of construction as to the use of section headings in the interpretation of provisions of the Criminal Code 1899 (Qld). Finally, it suggests that amendments should be made to the Acts Interpretation Act 1954 (Qld) in order to clarify the position as to the status of marginal notes and headings in statutory interpretation.

Literacy assessment that counts : mediating, interpreting and contesting translocal policy in a primary school

In Australia, as in many western education systems over the last two decades, discourses of accountability and performativity have reshaped education policy that has in turn reorganised the work of school leaders and teachers. One of the effects of this reorganisation is increased attention to the production, analysis and display of student achievement data. In this paper we examine in detail a sequence of the production and reading of literacy assessment data in a small Catholic school. Our analysis uses institutional ethnography’s concept of the ‘active text’, the text as occurring in a specific place and time even as it is articulated to social relations beyond its immediate context. Through this process we learn from those involved how their everyday work brings into being formalised, textually authorised processes in a local site that ensure the school meets accountability requirements while enabling teachers to resist standardisation of literacy teaching and assessment.

China's "Responsible Protection" concept : re-interpreting the Responsibility to Protect (R2P) and military intervention for humanitarian purposes

This article assesses the extent to which the recently formulated Chinese concept of “Responsible Protection” (RP) offers a valuable contribution to the normative debate over R2P’s third pillar following the controversy over military intervention in Libya. While RP draws heavily on previous proposals such as the original 2001 ICISS report and Brazil’s “Responsibility while Protecting” (RwP), by amalgamating and re-packaging these earlier ideas in a more restrictive form the initiative represents a new and distinctive interpretation of R2P. However, some aspects of RP are framed too narrowly to provide workable guidelines for determining the permissibility of military intervention for civilian protection purposes, and should therefore be clarified and refined. Nevertheless, the Chinese proposal remains significant because it offers important insights into Beijing’s current stance on R2P. More broadly, China’s RP and Brazil’s RwP initiatives illustrate the growing willingness of rising, non-Western powers to assert their own normative preferences on sovereignty, intervention and global governance.

Interpreting and comparing risks in the presence of competing events

Competing events are common in medical research. Ignoring them in the statistical analysis can easily lead to flawed results and conclusions. This article uses a real dataset and a simple simulation to show how standard analysis fails and how such data should be analysed

Interpreting scratch assays using pair density dynamics and approximate Bayesian computation

Quantifying the impact of biochemical compounds on collective cell spreading is an essential element of drug design, with various applications including developing treatments for chronic wounds and cancer. Scratch assays are a technically simple and inexpensive method used to study collective cell spreading; however, most previous interpretations of scratch assays are qualitative and do not provide estimates of the cell diffusivity, D, or the cell proliferation rate,l. Estimating D and l is important for investigating the efficacy of a potential treatment and provides insight into the mechanism through which the potential treatment acts. While a few methods for estimating D and l have been proposed, these previous methods lead to point estimates of D and l, and provide no insight into the uncertainty in these estimates. Here, we compare various types of information that can be extracted from images of a scratch assay, and quantify D and l using discrete computational simulations and approximate Bayesian computation. We show that it is possible to robustly recover estimates of D and l from synthetic data, as well as a new set of experimental data. For the first time, our approach also provides a method to estimate the uncertainty in our estimates of D and l. We anticipate that our approach can be generalized to deal with more realistic experimental scenarios in which we are interested in estimating D and l, as well as additional relevant parameters such as the strength of cell-to-cell adhesion or the strength of cell-to-substrate adhesion.

A roadmap for interpreting the literature on vision and driving

Over the past several decades there has been a sharp increase in the number of studies focused on the relationship between vision and driving. The intensified attention to this topic has most likely been stimulated by the lack of an evidence basis for determining vision standards for driving licensure and a poor understanding about how vision impairment impacts driver safety and performance. Clinicians depend on the literature on vision and driving to advise visually impaired patients appropriately about driving fitness. Policy makers also depend on the scientific literature in order to develop guidelines that are evidence-based and are thus fair to persons who are visually impaired. Thus it is important for clinicians and policy makers alike to understand how various study designs and measurement methods should be interpreted so that the conclusions and recommendations they make are not overly broad, too narrowly constrained, or even misguided. We offer a methodological framework to guide interpretations of studies on vision and driving that can also serve as a heuristic for researchers in the area. Here, we discuss research designs and general measurement methods for the study of vision as they relate to driver safety, driver performance, and driver-centered (self-reported) outcomes.

Criteria for interpreting kimberlite as coherent: Insights from the Muskox and Jericho kimberlites (Nunavut, Canada)

The Jurassic Muskox and Jericho kimberlites (Northern Slave Province, Nunavut, Canada) contain a variety of facies exhibiting different geometries, contact relationships, internal organisation, country rock abundance and olivine shapes, although many have similar matrix/groundmass mineralogies and textures. Five facies are examined that either have characteristics consistent with coherent rocks in general (i.e. intrusive and extrusive non-fragmental rocks) or are mineralogically and texturally similar to kimberlite described as coherent (or apparent coherent). Three facies are interpreted as coherent on the basis of: (1) geological setting, (2) apparent-porphyritic texture, (3) sharp contacts with fragmental kimberlite, (4) relative abundance of elongate and unbroken olivine crystals and (5) paucity of country rock xenoliths, while the remaining two facies are interpreted as fragmental on the basis of: (1) the gradational contacts with demonstrably fragmental kimberlite, (2) relative abundance and range of sizes of country rock lithic clasts and (3) numerous broken olivine crystals. Comparisons are made with coherent and apparent-coherent kimberlite from the literature. Our three coherent facies are similar to literature reported coherent kimberlite dykes hosted in country rock (CKd) in terms of internal organisation, low abundance of country rock xenoliths, and apparent-porphyritic texture. Conversely, our two fragmental facies share attributes with previously described pipe-filling coherent and apparent-coherent kimberlite (CKpf) in terms of geometry, internal organisation and abundance of country rock xenoliths. We conclude that CKd and most CKpf, although similar in matrix/groundmass mineralogy and texture, can be distinguished on the basis of internal organisation, country rock lithic clast abundance, texture (e.g. apparent-porphyritic texture) and possibly olivine crystal shapes and suggest that fragmental kimberlite is more common than reported.
