Cooperativas de vivienda: experiencia en Uruguay
Authors: Cabrera Melisa
Published: February 2019

El objetivo de la presente ponencia es exponer los principales lineamientos del modelo de cooperativa de vivienda en cesión de uso. Al hablar del acceso a la vivienda, como una necesidad básica que nos atraviesa a todas, aparece como una opción relevante pensar la resolución de esta necesidad a través de propuestas colectivas. Es a partir de esto que interesa presentar distintas experiencias que se vienen desarrollando desde hace varios años en distintos países, que promueven un modelo colectivo de acceso a la vivienda, mediante la gestión cooperativa, y que priman el derecho al goce y al uso de la vivienda, por sobre la especulación que hace de la misma como bien mercantilizado.

Published: February 2019

Diabetes mellitus (DM) is a chronic metabolic disorder. Streptozotocin is a naturally occurring cytotoxic chemical, particularly toxic to the pancreas and insulin producing beta cells in mammals and induces diabetes. Glimepiride is a second generation sulfonylurea, used as second-line or add-on treatment options for type 2 diabetes. Fenugreek (Trigonellafoenum graecum) seeds have been documented as a traditional plant treatment for diabetes. Soluble dietary fiber of Fenugreek significantly improved oral glucose tolerance in diabetic rats. It also exerts anti-diabetic effects mediated through the inhibition of carbohydrate digestion and absorption and the enhancement of peripheral insulin action. Most herbal remedies can interact with allopathic drugs resulting in altered activity and toxicity. At the same time, herbal remedies might produce the same kind of effects as the drug produce. Current published research information on herb-drug interactions is scanty. So, the aim of this study was to investigate the possible interaction between conventional drug used for the management of diabetes; (Glimepiride) and a traditional herbal remedy; Fenugreek aqueous extract in Streptozotocin induced diabetic male albino rats. In conclusion, combination therapy induces better hematological, biochemical effects and improves the oxidative stress biomarkers and antioxidant enzymes. Histological studies showed better results on some organ functions. The results emphasize the benefit of using the combination of Fenugreek seeds aqueous extracts as supportive complementary anti-diabetic therapy.
Neurobiological Differences Between Aggression and Agitation in Persons with DementiaAffiliation
Authors: Volicer Ladislav
Published: February 2019

Background
Controversy exists about definition of agitation and especially about inclusion of aggression as a part of agitation in people with dementia.

Methods: Papers describing neurobiological indices related to behavioral symptoms of dementia were reviewed. Papers comparing indices in persons exhibiting aggression and persons exhibiting agitation were selected for this review.

Results
The survey found seven papers which compared neuroanatomical indices and three papers which compared neurochemical indices. The neuroanatomical indices differentiating agitation and aggression included changes in brain perfusion, sizes of brain areas, distribution of neurofibrillary tangles, and white matter changes. The neurochemical indices differentiating agitation and aggression included relationships with neurotransmitter variables and the cell count in the locus coeruleus.

Conclusion
Despite the small number of papers and some methodological problems, the presented information clearly indicates that aggression and agitation are two distinct unrelated syndromes in persons with dementia.
The Public Work of Identity Performance: Advocacy and Dissent in Teachers’ Open Letters
Authors: Garahan Katie L.
Published: February 2019

In the rhetoric of contemporary federal education reform, public school teachers are often blamed for and championed as solutions to educational problems. Representations of teachers as heroic and blameworthy are an integral component of a neoliberal rationality apparent in education reform since the publication of the Reagan administration’s A Nation at Risk, as they allow political actors to promote individual solutions to systemic issues that affect student achievement. After briefly exploring the rhetoric of reform, this essay focuses on the ways teachers negotiate the discourses that implicate their profession. To do so, I analyze a corpus of 18 open letters written and published online by current and former public school teachers in protest of policy and/or specific political actors. I argue that authors of these open letters leverage their professional identities to protest and articulate alternatives to seemingly pervasive neoliberal logics inherent in contemporary education reform. In turn, I maintain that analyzing vernacular exchanges, such as teachers’ protest discourse, is imperative to understanding the material consequences of education policy as well as the full discursive space of policymaking.
Scientist Citizens: Rhetoric and Responsibility in L’Aquila
Authors: Pietrucci Pamela , Ceccarelli Leah
Published: February 2019

In this essay, we analyze the public communication debacle before the 2009 L’Aquila earthquake that led to the infamous trial of the “L’Aquila Seven.” Examining the trial transcripts to extract norms regarding the proper role of scientists in society, we conclude that the first verdict interpellated the figure of the responsible scientist citizen who is expected to perform rhetorical citizenship when communicating with a lay public, while the second assumed a distinction between public and technical spheres that absolves scientists from responsibility to their fellow citizens and reduces their role to performance of an expertise divorced from rhetoric. Tracing the civic outcomes of these conflicting norms, we identify three missed opportunities during the prequake discourse in which the scientists failed to correct statements that they, and only they, knew to be flawed. To prevent future communicative debacles that arise from a dangerous separation of scientists and laypeople, we argue that scientists need to come to see themselves as scientist citizens, experts who take on the civic responsibility of clearly communicating their knowledge to their fellow citizens when such sharing is necessary to the public good.

Published: February 2019

Debt policy is a decision made by a company to obtain funds from outside parties to meet the operational needs of the company. Recent economic development encourages compa-nies to continue to expand their business in order to survive and gain better corporate value. To develop the business, a company needs more funds. And when the funds are not enough, the company will perform debt policy. However, debt policy can be risky and therefore the company should carry out operational activities effectively in order to avoid the risks. This study aims to determine the effect of institutional ownership, managerial ownership, profitability, free cash flow, firm size and corporate growth on debt policy. The data used in this study are secondary data, that is, the financial reports of mining sector companies listed on the Indonesia Stock Exchange 2011-2015. The research is using purposive sampling method consisting of 59 data. Analysis techniques used in this study are classical assumptions and multiple regression analysis. The results show that institutional ownership and profitability have negative effect on debt policy, and free cash flow has positive effect on debt policy, while, managerial ownership, firm size, and corpo-rate growth have no effect on debt policy. The implication of this study is for investors to notice that the debt policy taken by mining companies is influenced by the number of shares owned by the institution, return on equity, and the amount of free cash flow.

Published: February 2019

National road management is not optimal and inefficient, the indications can be seen from the number of early damage cases of the road construction found. Indeed, natural damage to road construction is unavoidable but it becomes a problem if the damage occurs not long after the road product is handed over to the road manager or the government. Then the next question can arise whether the phenomenon of early pavement damage will cause harm to both road users and the government.This study aims to show the thinking framework of financial consequences and apply it through a model due to the occurrence of premature damage. Referring to the concept of benefit value that is represented by road conditions over the life of the service, then roads that have been damaged before their construction ends will result in losses due to loss of benefits. Based on this concept, a simulation was conducted using a national road data. Simulation results show that there is an estimated financial loss due to the occurrence of early damage. For early damage with a condition value of loss of 36 then the estimated loss is Rp 458,257,899.41 per kilometer. Estimated average loss per kilometer for each loss of one unit of condition value is Rp 12,72,386.09. The results of this study also show that roads that do not suffer early damage do not cause losses or losses are zero.

Sustainability is an effort to build an infrastructure by considering the environmental impacts that occur. Concrete production as a construction material that commonly used in infrastructure development is one contributor to carbon dioxide (CO2) emissions. CO2 is produced from the calcination process in the manufacture of cement, burning of fossil fuels, and electrical energy used. More specifically by reviewing the calcination process on cement making, it has evaluated the consumption of cement in concrete production. The Life Cycle Assessment (LCA) is an environmental impact evaluation in terms of the life cycle of a product, wherein this paper, using the cradle-to-cradle scope, LCA is used as a method to evaluate cement consumption in concrete production to concrete waste management by taking concrete waste at Construction Laboratory and Materials Diponegoro University, Semarang for the case study. The results of the evaluation stated that the use of geopolymer concrete with fly ash as a substitute for cement could reduce up to 80% CO2 emissions with concrete strength 75% larger than conventional concrete. And for the concrete waste management, Construction Laboratory and Materials Diponegoro University reused concrete cylinder waste as a substitute material to build the retaining wall.

Moisture content of tomato (Licopersicon esculentum Mill.) is very high, so easily damaged due to physical impact, enzyme and microbes activity. Further processing is necessary in order to improve shelf life, one way is drying method. This work studied the effect of foaming agent and cake thickness in tomato drying using tray dryer at various temperatures. Foaming agent is used to convert the material into foam, so that the drying temperature can be set relatively low to preserves color, aroma and nutrient composition of the material. The tray dryer is used, because it is simple and the operation cost is relatively cheap. In this work, tomatoes were sliced, crushed for 10 minutes using blender, separated from the seeds and residues with a 60 mesh sieve, and then mixed with dextrin and foaming agent Tween 80 each by 5% weight respectively. Each mixture was blended for 10 minutes. The tray dryer was filled with hot air at 2.0 m/sec with temperature variation of 40, 50, 60 and 70ºC and cake thickness variation of 2 and 4 mm. The results obtained, drying at 50° C is faster than 40º C, while 50 to 70º C is relatively the same. The thicker the cake, the slower the drying time. Performance of foaming agent Tween 80 compared to chemical foaming agent is a natural egg white powder. Drying with a foaming agent Tween 80 faster than egg white powder. Keywords: cake thickness; foaming agent; tomato; tray dryer

Detection of inhomogeneity by the observation of the surface of the material simulating biological tissues
Authors: Kmiecik Barbara , Detyna Jerzy
Published: February 2019

This paper presents a research which involves the observation of the movement of points presented on a material surface under the influence of mechanical extortion. Tests were performed using two 15 mm silicone layers, one of which contained 1 mm thick elements of nitrile-butadiene rubber. Analysed materials were structurally heterogeneous tissue phantoms. Test results that were obtained indicated that the developed method allows detecting inhomogeneity and its approximate location, what may be used in pathological state prevention.

In many industries and processes, heat exchangers are of vital importance as they are used to transfer heat from one fluid to another. These fluids can be corrosive to heat exchangers, which are usually made of metallic materials. This paper illustrates that corrosion is an important problem in the operation of heat exchangers in many environments, for which no straightforward answer exists. Corrosion failures of heat exchangers are common, and corrosion often involves high maintenance or repair costs. In this review, an overview is given of what is known on corrosion in heat exchangers. The different types of corrosion encountered in heat exchangers and the susceptible places in the devices are discussed first. This is combined with an overview of failure analyses for each type of corrosion. Next, the effect of heat transfer on corrosion and the influence of corrosion on the thermohydraulic performances are discussed. Finally, the prevention and control of corrosion is tackled. Prevention goes from general design considerations and operation guidelines to the use of cathodic and anodic protection.
Preparation of mineral bound particleboards with improved fire retardant and smoke suppression properties based on a mix of inorganic adhesive
Authors: Yang Kai , Li Xingong
Published: February 2019

An inorganic adhesive mix consisting of MgO, MgCl2, Na2SiO3, Na3PO4 was used to prepare mineral bound particleboard (mbPB) without formaldehyde emission and with excellent fire retardant and smoke suppression properties. The mechanical properties, interior microstructure, fire retardancy and smoke suppression behavior of the mbPB was investigated based on scanning electron microscopy (SEM) and cone calorimetric observations. The results showed that the presence of massive hydrates of the inorganic adhesive covers the mbPB particles, which are responsible for the positive effects. The effective smoke suppression was accompanied by an essential carbon monoxide (CO) and carbon dioxide (CO2) decrement in the gaseous effluents. The mbPBs are suitable as indoor material for wall, floor, and furniture as fire retardant and smoke suppressive materials.
Trans self-identification and the language of neoliberal selfhood: Agency, power, and the limits of monologic discourse
Authors: Zimman Lal
Published: February 2019

Sociocultural linguists share with transgender communities a strong interest in the power of individuals to assert agency over linguistic patterns. For trans people, a key principle of activism isgender self-determination, which treats each individual as the ultimate authority on their own gender identity. This article explores some of the ways gender self-determination and self-identification surface in transgender people’s linguistic practices. Three particular manifestations are highlighted: gendered identity labels, third person pronouns, and body part terminology. The observations offered on these subjects are based on a series of ethnographic projects carried out from 2006–2016 in transgender communities across several metropolitan areas in the United States and in online spaces frequented by trans people. However, the analysis goes beyond mere description by treating this kind of individualized linguistic agency as the product of cultural practice rather than an asocial given. Such a perspective introduces questions concerning why this form of agency arose in the time and place that it has. This article frames gender self-identification as an enactment of neoliberal personhood, in which individuals are framed as the driver of their destiny. What the ideology of neoliberal agency obscures, however, is that agency is not an equally distributed resource.

Objective

To examine the association between maternal diseases and congenital heart defects (CHDs) and to evaluate whether those associations vary with corresponding medication use.

Methods

A multi-hospital case-control study conducted from February 2010 to December 2014 analysed 916 controls and 1236 cases. Participating mothers were asked whether they suffered from influenza, common cold, herpes and threatened abortion or had used corresponding medication during the periconception period or the early pregnancy period. We used a random-effects logistic regression model to compute the odds ratios (ORs), adjusted odds ratios (AORs) and 95% confidence intervals (CIs) while controlling for potential confounders.

Results

Compared with the results for mothers with no exposure, there were significant associations between maternal diseases with medication non-use and CHDs in the aggregate, including influenza (AOR, 1.83; 95% CI, 1.13–2.95), common cold (AOR, 2.05; 95% CI, 1.60–2.64) and herpes (AOR, 7.00; 95% CI, 2.15–22.84). There was no significant association between medication users and offspring with any subtype of CHDs, except that maternal common cold with medication use slightly increased the risk of the specific subtype, namely, isolated cardiac defects. However, an association was observed between maternal threatened abortion and medication and isolated cardiac defects (AOR, 1.33; 95% CI, 1.01–1.75).

Conclusion

Maternal influenza, common cold, herpes and threatened abortion from 3 months before pregnancy through the first trimester were associated with an increased risk of congenital heart disease in offspring. The teratogenic effect of these conditions may be attenuated by medication use, except for threatened abortion.

Las interrogativas hipotéticas conquéinvariable en español: Un tipo de interrogativas parciales marcadas
Authors: Reig Alamillo Asela
Published: February 2019

Este trabajo analiza y describe, a partir de datos procedentes de corpora orales del español de España, la construcción interrogativa hipotética (¿Qué vienes, mañana?), un tipo de construcción interrogativa no descrita hasta el momento. Esta construcción sirve al hablante para realizar una pregunta parcial y presentar, al mismo tiempo, una posible respuesta que se infiere del contexto discursivo. Se trata de una pregunta parcial formalmente marcada: es encabezada por un pronombre interrogativo invariablequé, independientemente de la función sintáctica del constituyente interrogado; presenta un mínimo contenido presupuesto en la interrogación – típicamente, solo el contenido verbal –; e incluye una hipótesis respecto a la respuesta posible a la pregunta, típicamente inferida del discurso previo o del contexto discursivo inmediato.
