Extraction of reflected events from sonic-log waveforms using the Karhunen-Loève transform
Authors: Li Junxiao , Innanen Kristopher A. , Tao Guo
Published: June 2017

Sonic-reflection logging, a recently developed borehole geophysical scheme, is in principle capable of providing a clear view of outside the well bore. In this type of acoustic well logging, a key technical obstacle is that the reflected wave signal is almost entirely obscured by the directly arriving P-, S-, and Stoneley wave modes. Effective extraction of these reflection signals from the full acoustic waveforms is therefore a critical data-processing step. We have examined the use of the Karhunen-Loève (KL) transform, combined with a band-limiting filter, as a technique for the extraction of reflections of interest from a mixture with directly arriving wave modes of much higher amplitude. Under the assumption that large energy (squared-amplitude) differences exist between each wave component, the direct Stoneley wave, S-wave, and the P-wave are eliminated sequentially by subtracting the most significant principal components, after which the remaining signal is seen to be dominated by reflected events. Thereafter, the extracted reflections can be used in migration to provide interpretable images of the structures outside the borehole. Synthetic data are used to develop and justify our procedure for subtraction of appropriate KL principal components. Laboratory data are used to demonstrate in detail the suppression of unwanted modes. For comparison, the multiscale slowness-time-coherence method is applied to extract reflections from the same data set. The procedure is exemplified on a field data case with attention paid in particular to the consequences to imaging of near-borehole structures.
Computerised cognitive–behavioural therapy for adults with intellectual disability: randomised controlled trial
Authors: Cooney Patricia , Jackman Catherine , Coyle David , O'Reilly Gary
Published: June 2017

Background

Despite the evidence base for computer-assisted cognitive–behavioural therapy (CBT) in the general population, it has not yet been adapted for use with adults who have an intellectual disability.

Aims

To evaluate the utility of a CBT computer game for adults who have an intellectual disability.

Method

A 2 × 3 (group × time) randomised controlled trial design was used. Fifty-two adults with mild to moderate intellectual disability and anxiety or depression were randomly allocated to two groups: computerised CBT (cCBT) or psychiatric treatment as usual (TAU), and assessed at pre-treatment, post-treatment and 3-month follow-up. Forty-nine participants were included in the final analysis.

Results

A significant group x time interaction was observed on the primary outcome measure of anxiety (Glasgow Anxiety Scale for people with an Intellectual Disability), favouring cCBT over TAU, but not on the primary outcome measure of depression (Glasgow Depression Scale for people with a Learning Disability). A medium effect size for anxiety symptoms was observed at post-treatment and a large effect size was observed after follow-up. Reliability of Change Indices indicated that the intervention produced clinically significant change in the cCBT group in comparison with TAU.

Conclusions

As the first application of cCBT for adults with intellectual disability, this intervention appears to be a useful treatment option to reduce anxiety symptoms in this population.
Queer Postmodern Practices: Sex and Narrative inGravity’s Rainbow
Authors: Franco Marie
Published: June 2017

Offering a queer reading of Gravity’s Rainbow, this project reevaluates the sexual politics and narrative poetics at work in Thomas Pynchon’s paradigmatic postmodernist novel. Moving beyond a thematic reading of sexuality, the article articulates the unacknowledged theoretical similarities between postmodernist ontological instability and queer resistances to teleology. Building on the theoretical work of Brian McHale and Lee Edelman, I argue that Pynchon’s representations of sadomasochism in Gravity’s Rainbow become a destabilizing narrative force that queers Pynchon’s poetics. With a focus on Margherita Erdmann’s sexual practice, this revisionary reading of gender and female sexuality in Pynchon complicates previous criticism, which has largely condemned the heteromasculinity of high postmodernism and elided the power of female sexual agency in such texts.

Pathogenic helminths in the past: Much ado about nothing
Authors: Mulder Christian
Published: June 2017

Despite a long tradition on the extent to which Romanisation has improved human health, some recent studies suggest that Romanisation in general, and Roman sanitation in particular, may not have made people any healthier, given that in Roman times gastrointestinal parasites were apparently widespread, whilst in the present day such parasites rarely cause diseases. Unfortunately, this novel claim neglects the empirical evidence that worldwide infections in over 1.5 billion people are caused by ubiquitous foodborne nematodes. Therefore, many may wonder if fossil remains of soil-transmitted helminths have been reported in ancient sanitation infrastructures. Beneficial access to improved sanitation should always be prioritized, hence how can historical sanitation efforts have ever been harmful? In this short article, a strong plea for caution is given, asking for an augmented nematological record and showing that there is not any evidence against Roman sanitation, neither in the past nor in the present.

Published: June 2017

For successful development serious support is required most new scientific directions at the level of the state. In 2007 nanotechnologies got in the group of such perspective directions. After almost ten years there is a need to assess the pace of industry development and efficient use of budget funds. When searching for information placed in the public domain, the authors faced the problem of its closeness. As a result, the analysis was built on the data of Federal Service of State Statistics and statements of JSC «RUSNANO» for 2010–2015 years, in particular, we studied the dynamics of devised and used nanotechnology, nanotechnology industry in output production, and distribution enterprises producing nanoproducts for subjects of the Russian Federation. The executed research allows to say that the nanoindustry in the Russian Federation in the period from 2010 to 2015 was developed, but the growth rate is constantly decreasing. The economic crisis that has evolved over the years 2014–2016 showed the ability of enterprises to ensure the development of the nanoindustry in a difficult situation.

Cooperation of Russia and China in the global financial system
Authors: Аккузина  , Akkuzina Maria
Published: June 2017

The article considers cooperation of Russia and China in the financial and trading platforms, which annually is steadily increasing in extent, especially in terms of sanctions imposed on Russia by the European countries. Chinese policy is aimed at liberalization of currency transactions, which creates favorable conditions for the development of monetary cooperation between Russia and China. Trend of Russian-Chinese cooperation appear to be quite optimistic: Chinese banks increase the size of trade financing and limits of loans that they provide to Russian banks. According to experts, for further mutually beneficial cooperation in the financial sector, the priorities should be: raising funds for Chinese investors in Russia due to host a variety of fixed income Russian securities, which are denominated in rubles.
Not Just a Fad: Optimal Sequencing in Mobile In-App Advertising
Authors: Sun Zhen , Dawande Milind , Janakiraman Ganesh , Mookerjee Vijay
Published: June 2017

In this paper, we address the challenge faced by ad networks in managing the fading ads (or fads) shown to an end user during a session of a mobile application (app). A fad is an ad that disappears if the user does not interact with it for some length of time. The withdrawn ad could be replaced by another ad. The goal of the ad network is to determine the sequence of fads shown to the user in an ad space to maximize the expected revenue generated over the user’s app session. Mobile in-app advertising is uniquely suited for the sequencing of fads because user sessions are typically longer (than web sessions), and a single ad is displayed at any given point in time. We consider two factors that affect the probability of a click on an ad during a session: (i) the sojourn effect, the influence of the passage of time, and (ii) the exposure effect, the influence of the number of prior exposures of the ad to the user during that session. We provide simple and optimal policies for the ad-sequencing problem when either of these two effects dominates. For the general case in which both effects are significant, we offer a provably near-optimal heuristic policy. The following two enhancements to the basic sequencing problem are also analyzed: (a) consideration of both click ads (which generate revenue for the ad network only through clicks) and display ads (which generate revenue only through exposures) and (b) the presence of a constraint imposed by the publisher (i.e., the owner of the app) that the expected revenue in each time slot exceeds a certain threshold.

First pass metabolism
Authors: Robertson Deborah
Published: June 2017

In this article in the series of ‘bite sized’ pharmacology, we will look at the concept of first pass metabolism. All drugs given by the oral route undergo a degree of first pass metabolism either in the gut or the liver, with some drugs being destroyed before they reach the systemic circulation. This pharmacokinetic process affects the bioavailability of drugs administered by this route and is an important consideration for the prescriber. Knowledge of first pass metabolism can assist the prescriber when deciding on doses and dose schedules to ensure that patients receive their medications at the correct dosing, by the correct route for optimum therapeutic effect. It also helps the prescriber understand why dose adjustments are made for some drugs when switching the route of administration from oral and why some drugs cannot be given by the oral route.
From context to subject: The poetics and politics of creating and exhibiting artworks in the National Museum of China
Authors: Yin Tongyun
Published: June 2017

Prior to its renovation and reopening in 2011, the National Museum of China, originally the Museum of Chinese History and the Museum of Chinese Revolution sharing the same building structure, has been the official trustee and the authoritative voice of Chinese history since 1949. However, in the past five years, the Museum has significantly shifted its focus from history to art as the pace of the nation’s socioeconomic transition accelerated, a tendency summarized in its mission to transform the Museum into the “largest art and history museum” in the world. Based on the studies of the exhibitions held at the Museum in the past few decades, this paper examines the transformation of the exhibitionary practices of the NMC first through the lens of artworks created by official commissions in Socialist China and by reconstructing cultural relics into ‘Chinese art’ in post-Socialist China. Then, it analyses the altering interpretative narratives and presentational approaches used to exhibit artworks against the nation’s rapidly changing social-cultural and economic contexts. The article aims to analyse the changing roles played by art to foster and uphold shifting discourses to justify the Party-State’s political legitimation and promote cultural nationalism for nation-building. It further reveals how power, politics and ideology operate in exhibitions in contemporary China.
Between global models and local resources: Building private art museums in Shanghai’s West Bund
Authors: Zennaro Giulia
Published: June 2017

Increasingly, the establishment of museums has developed as a strategy for improving local attractiveness and economy. Recently, in China, art museums – often in private form – have witnessed a rapid development. However, despite enhanced governmental support, some of these new art endeavours still face challenges in their operation. I argue that a major factor contributing to these obstacles can be found in the relation between local governments’ ambitions to design museums similarly to other world-renowned ones (isomorphism) and the availability of local resources and expertise. In particular, my case study on the Long Museum and the Yuz Museum (in the Shanghai West Bund) shows how focusing on the achievement of globally favoured aesthetic standards vis-à-vis local resources to enhance the credibility of these new undertakings (legitimacy) has occasionally obstructed organizational efficiency, specifically in this case, of the museums’ function to store and display art.

Large area nanoimprint by substrate conformal imprint lithography (SCIL)
Authors: Verschuuren Marc A. , Megens Mischa , Ni Yongfeng , van Sprang Hans , Polman Albert
Published: June 2017

Releasing the potential of advanced material properties by controlled structuring materials on sub-100-nm length scales for applications such as integrated circuits, nano-photonics, (bio-)sensors, lasers, optical security, etc. requires new technology to fabricate nano-patterns on large areas (from cm2 to 200 mm up to display sizes) in a cost-effective manner. Conventional high-end optical lithography such as stepper/scanners is highly capital intensive and not flexible towards substrate types. Nanoimprint has had the potential for over 20 years to bring a cost-effective, flexible method for large area nano-patterning. Over the last 3–4 years, nanoimprint has made great progress towards volume production. The main accelerator has been the switch from rigid- to wafer-scale soft stamps and tool improvements for step and repeat patterning. In this paper, we discuss substrate conformal imprint lithography (SCIL), which combines nanometer resolution, low patterns distortion, and overlay alignment, traditionally reserved for rigid stamps, with the flexibility and robustness of soft stamps. This was made possible by a combination of a new soft stamp material, an inorganic resist, combined with an innovative imprint method. Finally, a volume production solution will be presented, which can pattern up to 60 wafers per hour.
Design of a Miniaturized X-Band Diplexer Based on Novel One-Third-Mode Substrate Integrated Resonator Filters
Authors: Zhang Hao , Kang Wei , Wu Wen
Published: June 2017

In this paper, a miniaturized diplexer designed with two novel one-third-mode substrate integrated resonator (OTMSIR) filters has been presented. The one-third triangular resonator cavity with two transmission zeros (TZs) and two transmission poles is investigated. TZs are implemented by taking cross couplings of lower order modes in this design. The diplexer is then obtained by integrating two different sizes of OTMSIR filters with a common T-junction structure. A X-band diplexer operating at 10 GHz and 11.5 GHz is designed on a substrate with a dielectric constant of 3.55 to verify the above design concept. This novel structure features more compact size, better transmission performance, higher out of band rejection and easier integration compared with other circuits. A good agreement is obtained between the simulations and the measured results.
Capital Valuation, What is it and Why does it Matter? Insights from Austrian Capital Theory
Authors: Lewin Peter
Published: June 2017

The ability to rationally evaluate time-consuming productive activities is what distinguishes capitalism from alternative social systems. Capital-accounting provides the framework for such evaluations that allow decision-makers to calculate the relative values to them of alternative productive activities. In this paper I show how insights from Austrian Capital Theory help to understand this process of evaluation. Austrian economics stresses that evaluation is an essentially subjective process. Entrepreneurs’ estimates of future earnings, which depend on the consumers’ subjective evaluations of the produced products, will vary and they must compete for productive resources in a dynamic trial and error social process. Entrepreneurial evaluations, nevertheless, can be described in terms of familiar financial concepts that encapsulate both the capital-value and the duration of any contemplated business venture. Value and time are the two essential dimensions of dynamic business valuation. I examine these concepts with a view to describing that social process, using what can be known and what needs to be imagined. I conclude that there is no silver bullet formula or method to evaluate a business that would give an objectively correct answer – obviously not, or else we would not have need of a competitive market process – but there
The effect of TiO2 component on the properties of acrylic and urea-aldehyde resins under accelerated ageing conditions

Synthetic resins were introduced in paintings conservation during the 1930s, as an alternative to natural resins, due to their superior resistance to degradation. Their composition usually includes a small amount of additives, such as titanium dioxide. The objective of this work is to study the effect of TiO2 additive on the durability of Paraloid B72 (acrylic resin) and Laropal A81 (urea-aldehyde condensation polymer), both used in art conservation, against photochemical degradation. A methodology involving separating particulate TiO2 from the organic fraction of the resins has been applied, followed by accelerated ageing of the resins in their commercial (C) and modified (M, i.e. after TiO2 removal) has been implemented. The morphological characteristics of resin films were examined through scanning electron microscopy (SEM). Chemical changes, colour properties and photo-chemical stability of the resins were studied with FTIR, UV-Vis absorption spectroscopy and spectro-colorimetry. The results showed a considerably different behaviour between the C and M states of both materials. In particular, C-Paraloid B72 collapses after prolonged irradiation, but within a certain time frame it appears to be relatively stable; on the other hand, C-Laropal A81 is considerably destabilized in comparison to its M state. It can be suggested that TiO2 acts as a UV-blocker for the underlying pigment layers, at the expense of resins’ stability.
Effect of Primary Rocket Jet on Thermodynamic Cycle of RBCC in Ejector Mode
Authors: Lin Binbin , Pan Hongliang , Shi Lei , Ye Jinying
Published: June 2017

Thrust augmentation in ejector mode is important to improve engine performance so as to enable more propulsion applications of RBCC. Usually, the internal flow-path is configured mainly for combustion organization in ramjet and scramjet modes, thus the RBCC performance in ejector mode will mainly depend on the primary rocket operating parameters and jet expansion state. Considering such restrictions and requirements on the primary rocket, this paper studies the effects of the primary rocket jet on the thermodynamic cycle performance of ejector mode, in which incoming air is dominated by ejector-suction by the primary rocket jet at low flight Mach numbers. It is found that the engine performance in ejector mode will be improved by increasing the primary rocket chamber pressure and nozzle expansion ratio. Furthermore, for better design of primary rocket, primary rocket chamber pressure should be maximized on the basis of ensuring a complete expansion of primary rocket to the ambient pressure at the design point of flight conditions after 3-D CFD simulations for a full flow-path of RBCC including fore-airframe and aft-airframe of a flight vehicle. The results of 3-D numerical simulations show that the bypass ratio and specific impulse increase by 35.5 % and 12.5 % respectively at sea-level static condition.

Heart failure (HF) is a debilitating and life-threatening condition, with 5-year survival rate lower than breast or prostate cancer. It is the leading cause of hospital admission in over 65s, and these admissions are projected to rise by more than 50% over the next 25 years. Transthoracic echocardiography (TTE) is the first-line step in diagnosis in acute and chronic HF and provides immediate information on chamber volumes, ventricular systolic and diastolic function, wall thickness, valve function and the presence of pericardial effusion, while contributing to information on aetiology. Dilated cardiomyopathy (DCM) is the third most common cause of HF and is the most common cardiomyopathy. It is defined by the presence of left ventricular dilatation and left ventricular systolic dysfunction in the absence of abnormal loading conditions (hypertension and valve disease) or coronary artery disease sufficient to cause global systolic impairment. This document provides a practical approach to diagnosis and assessment of dilated cardiomyopathy that is aimed at the practising sonographer.
Feasibility of physiologist-led stress echocardiography for the assessment of coronary artery disease
Authors: Khan Jamal N , Griffiths Timothy , Fatima Tamseel , Michael Leah , Mihai Andreea , Mustafa Zeeshan , Sandhu Kully , Butler Robert , Duckett Simon , Heatlie Grant
Published: June 2017

Background

Physiologist-led stress echocardiography (PLSE) services provide potential for expansion of SE services and increased productivity for cardiologists. There are however no published data on the feasibility of PLSE. We sought to assess the feasibility, safety and robustness of PLSE and cardiologist-led stress echocardiography (CLSE) for coronary artery disease (CAD) assessment.

Methods

Retrospective analysis of 898 patients undergoing PLSE or CLSE for CAD assessment using exercise or dobutamine stress over 24 months. PLSE involved 2 cardiac physiologists (exercise) or 1 physiologist plus 1 cardiac nurse (dobutamine). A cardiology registrar was present in the echocardiography department during PLSE in case of medical complications. CLSE involved 1 physiologist and 1 trainee cardiologist who analysed the study and reviewed findings with an imaging cardiologist. Sixteen-segment wall motion scoring (WMS, WMSI) analysis was performed. Feasibility (stressor, image quality, proportion of completed studies, agreement with imaging cardiologist analysis) and safety (complication rate) were compared for PLSE and CLSE.

Results

The majority of studies were CLSE (56.2%) and used dobutamine (68.7%). PLSE more commonly used exercise (69.2%). Overall, 96% of studies were successfully completed (>14 diagnostic segments in 98%, P = 0.899 PLSE vs CLSE). Commencement of PLSE was associated with an increase in annual SE’s performed for CAD assessment. Complication rates were comparably very low for PLSE and CLSE (0.8% vs 1.8%, P = 0.187). There was excellent agreement between PLSE and CLSE WMS interpretation of 480 myocardial segments at rest (κ = 0.87) and stress (κ = 0.70) and WMSI (ICCs and Pearson’s r >0.90, zero Bland–Altman mean bias).

Conclusion

This to our knowledge is the first study of the feasibility of PLSE. PLSE performed by well-trained physiologists is feasible and safe in contemporary practice. PLSE and CLSE interpretation of stress echocardiography for CAD agree very closely.
El buen vivir y la crítica del universalismo abstracto
Authors: Cruz Edwin
Published: June 2017

Este artículo reconstruye la crítica que desde el proyecto del VBBV se puede plantear al universalismo abstracto encarnado en el discurso del desarrollo. El argumento central es que el VBBV se constituye como una alternativa a la crisis ambiental y civilizatoria contemporánea que, frente al universalismo abstracto del discurso desarrollista, reivindica un diálogo intercultural para construir relaciones de complementariedad y convivencia entre seres humanos y entre éstos y la naturaleza. En primer lugar, se examina el desarrollo como un ejemplo de universal abstracto. En las tres partes siguientes se estudian las críticas que el VBBV plantea a la concepción lineal de la historia, a la concepción antropocéntrica e instrumental de la naturaleza y al carácter colonial del discurso del desarrollo.

Published: June 2017

During ongoing proteomic analysis of the soybean (Glycine max (L.) Merr) germplasm collection, PI 603408 was identified as a landrace whose seeds lack accumulation of one of the major seed storage glycinin protein subunits. Whole genomic resequencing was used to identify a two-base deletion affecting glycinin 5. The newly discovered deletion was confirmed to be causative through immunological, genetic, and proteomic analysis, and no significant differences in total seed protein content were found to be due to the glycinin 5 loss-of-function mutation per se. In addition to focused studies on this one specific glycinin subunit-encoding gene, a total of 1,858,185 nucleotide variants were identified, of which 39,344 were predicted to affect protein coding regions. In order to semiautomate analysis of a large number of soybean gene variants, a new SIFT 4G (Sorting Intolerant From Tolerated 4 Genomes) database was designed to predict the impact of nonsynonymous single nucleotide soybean gene variants, potentially enabling more rapid analysis of soybean resequencing data in the future.

Aim. To investigate the antibacterial properties of the fl owers of melliferous plants on the cultures isolated from honeycombs affected by foulbrood. Methods. Microbiological, cultural-morphological, biochemical, electron- microscopic, statistical. Results. Antibacterial effect on the Melissococcus pluton 8.1 strain was demonstrated by the fl ower extracts of 14 plant species and that on Bacillusaspecies – by the fl ower extracts of 27 plant spe- cies blossoming in the early spring. Conclusions. To study bee colonies affected by foulbrood, it is possible to use the properties of such nectariferous plants as Lamium album, Acer campestre, Prunus tomentosa, Allium cepa, Tagetes patula, Spiraea japonica, Achillea millefolium, Calluna vulgaris, Mentha piperita, Tilia cordata, Centaurea jacea, Lysimachia nummularia. The results of the experiments on the culture of microorganisms, isolated from the honeycombs of the bee colonies affected by foulbrood, demonstrated that these plants could be effective for the
prevention and treatment of bacterial bee diseases.
Influence of abiotic factors on photosynthesis and production process of different winter wheat varieties
Authors: Guliaev B. , Huliaieva H. , Patyka V.
Published: June 2017

Aim. The investigation of photosynthesis and production process in winter wheat varieties, different in their grain productivity, its connection to the active surface area of the root system in optimal conditions, under drought and mineral nutrition defi ciency. Methods. Physiological, biochemical, gas exchange analysis, statisti- cal methods. Results. It was demonstrated that different conditions of mineral nutrition and soil drought have impact on the intensity of photosynthesis, photo- and dark respiration, the content of pigments in the fl ag leaf of winter wheat plants; the results obtained testify to the interrelation of these indices to the active surface area of the root system and grain productivity of winter wheat varieties, different in potential grain productivity. Conclusions. It was determined that under drought the photosynthetic apparatus of a highly productive winter wheat variety Smuhlianka demonstrated higher stability compared to the photosynthetic apparatus of the vari- ety Myronivska
808, moderately resistant to drought conditions. At the same time, highly intensive varieties of winter wheat, Favorytka and Smuhlianka, had a larger active surface area of the root system and chlorophyll content in leaves, compared to Myronivska 808 plants, notable for their lower grain productivity. It was deter- mined that there was considerable reliable correlation between the intensity of fl ag leaf photorespiration and the active surface area of the root system in winter wheat plants of varieties Myronivska 808 and Smuhlianka (r = 0.805). Considerable correlation (r = 0.878) was found between the intensity of fl ag leaf photorespiration in the heading-blossoming phase and the sum of chlorophylls in these leaves. It was determined that the index S r act × chlorophyll may be used to estimate the active surface area of the root system with the error of up to 3.8 % for fi ve winter wheat varieties.

A partir de estudo teórico e de uma análise situacional, almeja discutir as relações entre educação patrimonial, processos identitários e reelaboração das demarcações simbólicas tomando como elemento reflexivo a situação do tombamento histórico realizado em Antônio Prado, RS, no final da década de 1980, e seus desdobramentos pedagógicos e sociais na atualidade.
Mulheres, investigação de paternidade e justiça: cotidiano e provas (Belém, 1920-1940)
Authors: Campos Ipojucan Dias
Published: June 2017

O artigo possui como proposta de análise perceber como algumas mulheres e filhos adultos das décadas iniciais do século XX, na cidade de Belém, se articularam tanto no cotidiano quanto no bojo do judiciário para provarem paternidade; assim as interpretações giraram em torno de tramas e lutas de mulheres que constituíram famílias ditas à época “espúrias”, às margens do ato solene. Em conformidade, para estes encaminhamentos tomou-se como argumento a concepção de que o tempo de vida sob um mesmo teto sempre se demonstrou princípio indispensável aos que impetravam, aos impetrados, às testemunhas e aos juízes das demandas, porque era em seu interior (no do tempo de convivência) que se buscavam comprovar contatos íntimos e consequentes nascimentos que por razões várias (de o pai ser casado com outra mulher, por exemplo) os impúberes não foram registrados. Nesta seara, é de bom alvitre considerar que as(os) solicitantes em “nada” se sustentavam no desejo de possuir o sobrenome do pretendido genitor, mas sim no de resolver necessidades materiais, as quais poderiam ser “contornadas” por meio de herança e pensão alimentícia.

Reflexões acerca do cotidiano de mulheres trabalhadoras rurais “boias frias” na cultura canavieira do interior paulista
Authors: BEZERRA ANTONIO ALVES
Published: June 2017

Este artigo reflete acerca das experiências de lutas vivenciadas por mulheres trabalhadoras rurais “boias-frias”que atuaram na cultura canavieira no oeste paulista,nos primórdios do século XXI. Por meio da História Oral e dos estudos de gênero enquanto categoria de análise, evidencia a maneira pelas quais essas trabalhadoras percebem e explicam a sua segregação no mundo do trabalho e a exploração do capitalismo implementado em larga escala no setor sucroalcooleiro a partir dos anos de 1960. Além disso, o artigo discorre sobre os registros, nas memórias dessas mulheres, das transformações no campo, e sobre suas perspectivas de futuro no universo do trabalho rural em constante modificação. Utilizando essa metodologia de pesquisa, são explicitadas algumas das interfaces que marcaram as experiências de vida e de lutas das trabalhadoras rurais cortadoras decana das Usinas Nova América e Maracaí (complexos sucroalcooleiros alocados na região de Assis, interior paulista).As reflexões do artigo partem da análise das falas das trabalhadoras,entrevistadas à luz de referenciais teóricos, em busca de se compreender as interfaces de suas experiências de lutas e sobrevivência,tanto no campo dos canaviais, quanto no espaço do lar, problematizando os diferentes contextos dos eu cotidiano,com base no reconhecimento de que são sujeitos sociais e históricos.
Un centro cívico o el réquiem del patrimonio urbano costarricense
Authors: Muñoz Muñoz Marcela
Published: June 2017

Resumen Se ofrece una honra póstuma a la arquitectura pública de la capital costarricense, San José, como modelo de ciudad nacional. Por medio del estudio de una discusión legislativa se aborda la conveniencia de dotar al país de un centro cívico nacional, la cual favorece la [in]comprensión de un urbanismo incipiente, anterior a 1970, década en la cual se consolida el derecho urbanístico. Mediante el símil del réquiem, la historia del derecho urbanístico reclama la inutilidad de soluciones jurídicas por salvar valiosas edi caciones que vieran la luz en la conformación del Estado Nacional, durante los siglos XIX y XX. El afán de modernidad de Costa Rica requiere que el derecho urbanístico halle nuevas formas de entender el patrimonio urbano. Abstract This article offers a posthumous honor for public architecture of the Costa Rican capital, San José, as a national model of a city. The study of the discussion contained in certain legislative acts around the convenience to give the country a National Civic Center, [do not] favors the understanding of an emerging Urban Planning before 1970’s, the “legal” decade for the Urban Law. By using the analogy of the requiem, the History of Urban Law demands the futility of legal solutions to save valuable buildings that were born in the formation of the National State, during the 19th and 20th centuries. The Costa Rica ́s quest for modernity claims for new ways where Law can understand Urban Heritage.
Viabilidad para la implementación de estrategias de renovación urbana en Costa Rica
Authors: Chavarría Núñez Dania
Published: June 2017

ResumenEn los últimos años se han realizado en Costa Rica algunos esfuerzos para desarrollar normativa urbana que facilite la intervención dentro de las ciudades existentes, con el fin de revitalizar los centros urbanos y atraer nuevamente a la población que por diversas causas renunció a vivir en la ciudad. Las estrategias de Renovación Urbana han desempeñado un papel importante en las transformaciones socio-espaciales que han experimentado muchas ciudades del mundo, las cuales incorporan herramientas novedosas para intervenir dentro del entorno construido y contemplan una serie de instrumentos que permiten corregir las tendencias negativas que genera el modelo de ciudad dispersa, y a su vez devolver la funcionalidad y el atractivo a sectores estratégicos con el fin de construir un nuevo modelo de ciudad más sostenible e inclusiva. El presente artículo tiene como propósito analizar las posibilidades que existen en el país para implementar estrategias de renovación urbana, tomando como marco base la legislación urbana existente. Con el fin de evidenciar este supuesto se analiza la normativa vigente y se pone en evidencia como dicha legislación faculta a los municipios para ejercer competencias en la planificación urbana y el ordenamiento de su territorio. Se da un énfasis particular a la viabilidad para desarrollar e implementar estrategias de renovación urbana en la escala local, la cual se fundamenta en la Ley de Planificación urbana 4240 y se fortalece con los avances más recientes que se han dado en el país en materia de actualización normativa.AbstractIn Costa Rica, in recent years, efforts have been made to develop urban regulations to facilitate intervention within existing cities, with the aim of revitalizing urban centers and attracting the population that for a number of reasons has renounced living in the city. Urban renewal strategies have played an important role in the socio-spatial transformations that have been experienced in those cities around the world which incorporate creative tools to intervene within the built environment and contemplate a series of instruments that allow to correct the negative tendencies generated by the model of dispersed city and at the same time return the functionality and appeal to¡ strategic sectors in order to build a new model of a more sustainable and inclusive city.The purpose of this article is to analyze the possibilities that exist, based on existing urban legislation in the country, to implement strategies of urban renewal. In order to test this assumption, the current legislation is analyzed, evidencing the degree to which it empowers municipalities to exercise its prerogatives in urban planning and the organization of their territory. Particular emphasis is given to the feasibility of developing and implementing urban renewal strategies at the local scale, which is based on the Ley de Planificación Urbana N° 4240 and is strengthened by the most recent advances inthe country in terms of normative update.
