BACTERIAL EXOPOLYSACCHARIDE-MEDIATED SYNTHESIS OF SILVER NANOPARTICLES AND THEIR APPLICATION ON BACTERIAL BIOFILMS
Authors: Margaret Galvez Adrianne , Mae Ramos Kimberly , Julianne Teja Alexis , Baculi Ronan
Published: February 2019

The development of multi-drug-resistant bacteria and their biofilm formation capabilities has decreased the effectiveness of antibiotics and other antimicrobial agents. Silver nanoparticle (AgNP) is currently being explored as an alternative strategy in countering biofilm-related infections. In this study, AgNP was biosynthesized using the extracted exopolysaccharide (EPS) from two obligate alkaliphilic bacteria, Bacillus krulwichiae M2.5 and Bacillus cellulosilyticus M4.1, isolated from a hyperalkaline spring in Zambales, Philippines. The samples exhibited an absorption peak at around 420 nm corresponding to the surface plasmon resonance of AgNPs as shown by UV-Vis analysis. The Fourier transform infrared (FTIR) spectroscopy spectra revealed functional groups in the EPS such as hydroxyl and carboxyl involved in the reduction of Ag+ to AgNP. Scanning electron microscopy (SEM) coupled with energy dispersive X-ray (EDX) spectroscopy showed stable irregular and spherical AgNPs with an average size of 25.88 ± 10.49 nm and 23.99± 8.43 nm for B. krulwichiae M2.5 EPS-AgNP and B. cellulosilyticus M4.1 EPS-AgNP, respectively. The biosynthesized AgNPs significantly inhibited the biofilm formation of Pseudomonas aeruginosa, Klebsiella pneumoniae and Staphylococcus aureus in a dose-dependent manner as determined by microtiter plate assay. However, the results showed a reduced inhibitory effect of the synthesized AgNPs on established biofilms indicating the need for higher AgNP concentration. This study demonstrates that EPS from bacteria adapted to alkaline conditions can be used for efficient AgNP biosynthesis with potential biomedical applications.

Published: February 2019

The use of herbicides has become a potential tool in modern agriculture to get rid of weeds menace, but unknowingly the indiscriminate application of herbicides has resulted in adverse effects on the morphological, physiological and biochemical characteristics of crop plants. Herbicide effect of triazine herbicide (solo applied, or in combinations with regulators of polyamine biosynthesis: γ-aminobutyric acid, propylenediamine and salicyl acid) and quantitative parameters of spring barley (variety Kompakt) was evaluated under simulative conditions of hydroponic experiments under light platform. The experiment was carried out in hydroponics under light platform with linear fluorescent lamp at Department of chemistry SUA Nitra, where 9 pots was used with 24 barley grains/per pot of variety Kompakt and 5.5 litres of mineral solution, which were prepared from stock solutions containing optimal content of macro-elements (K, P, N, Ca, Mg) and micro-elements (B, Mn, Cl, Zn, S, Cu, Mo, Fe) for plants. At hydroponic experiment short-time negative effect of triazine herbicide at formation of biomass and root system and more significant negative influence at the amount of formed fresh biomass and root system were observed. Our experiments after foliar treatment of barley plants with herbicide confirm minimal short-time negative effect of mentioned herbicide. It indicates lowering of the amount of retained water in roots. Regulators of polyamine biosynthesis in hydroponics reduced inhibitory effect of tested pesticide on formation of organic matter, while their influence was manifested on amount of produced fresh biomass and root matter than on amount of dry matter. The most suitable doses of 100 g.ha-1 degradation product putrescine - GABA (γ-amino-butyric acid) and 59.2 g.ha-1 degradation product spermidine and spermine - DAP (1,3- propylendiamine) were used on elimination of negative effects of triazine herbicide in barley.

The paper is focused on monitoring of the content of selected elements (Al, Cd, Cu, Hg, Pb, Se and Zn) in three species of edible mushrooms: Cantharellus cibarius Fr., Suillus luteus (L.) Roussel and Imleria badia (Fr.) Vizzini from three areas in Slovakia (Prašice, Bobrov and Dobroč). Qualitative and quantitative determination of the observed elements was performed by ICP-OES and/or CV-AAS.
All results were statistically evaluated at both descriptive and differential analysis level. Due to the fact that picking and subsequent consumption of edible wild mushrooms is popular in Slovakia, the data obtained were evaluated and compared to tolerable weekly intakes defined by WHO. Based on the content of the monitored elements, PTWI values were not exceeded in any of the species from the studied sites. In some cases, however, specific content values, especially Al, but also Cd and Hg were exceeded compared to the average concentrations of elements in mushrooms from uncontaminated areas. In general, it can be stated that regular and long-term consumption of the mushrooms does not pose any health risk to the consumers.

Authors: Cox Joanne E. , Harris Sion Kim , Conroy Kathleen , Engelhart Talia , Vyavaharkar Anuradha , Federico Amy , Woods Elizabeth R.
Published: February 2019

BACKGROUND:

Teen mothers often present with depression, social complexity, and inadequate parenting skills. Many have rapid repeat pregnancy, which increases risk for poor outcomes. We conducted a randomized controlled trial of a parenting and life skills intervention for teen mothers aimed at impacting parenting and reproductive outcomes.

METHODS:

Teen mothers were recruited from a teen-tot clinic with integrated medical care and social services. Participants were randomly assigned 1:1 to receive (1) teen-tot services plus 5 interactive parenting and life skills modules adapted from the Nurturing and Ansell-Casey Life Skills curricula, delivered by a nurse and social worker over the infant’s first 15 months or (2) teen-tot services alone. A computerized questionnaire was self-administered at intake, 12, 24, and 36 months. Outcomes included maternal self-esteem, parenting attitudes associated with child maltreatment risk, maternal depression, life skills, and repeat pregnancy over a 36-month follow-up. We used generalized linear mixed modeling and logistic regression to examine intervention effects.

RESULTS:

Of 152 invited, 140 (92%) participated (intervention = 72; control = 68). At 36 months, maternal self-esteem was higher in the intervention group compared with controls (P = .011), with higher scores on preparedness for mothering role (P = .011), acceptance of infant (P = .008), and expected relationship with infant (P = .029). Repeat pregnancy by 36 months was significantly lower for intervention versus control participants.

CONCLUSIONS:

A brief parenting and/or life skills intervention paired with medical care for teens and their children has positive effects on maternal self-esteem and repeat pregnancy over 36 months.
Microporous Polysaccharide Hemosphere Absorbable Hemostat (AristaAH®) in Re-Operative Cardiac Surgical Procedures
Authors: Bruckner Brian A , Loebe Matthias
Published: February 2019

Patients undergoing re-operative cardiac surgical procedures present a great challenge with regard to obtaining hemostasis in the surgical field. Adhesions are ever-present and these patients are often on oral anti-coagulants and platelet inhibitors. As part of a well-planned surgical intervention, a systematic approach to hemostasis should be employed to decrease blood transfusion requirement and improve patient outcomes. Topical hemostatic agents can be a great help to the surgeon in achieving surgical field hemostasis and are increasingly being employed. Our approach, to these difficult patients, includes the systematic and planned use of AristaAH, which is a novel hemostatic agent whose use has proven safe and efficacious in our patient population.
Una caracterización de los predios del borde urbano-rural de Bogotá D.C., desde sus variables catastrales
Authors: Rodríguez Beltrán Carlos Alberto
Published: February 2019

El presente trabajo contribuye a caracterizar los predios del borde urbano-rural (BUR) de Bogotá D. C., mediante el análisis de la información de la base catastral con corte al año 2015 de 73.868 predios ubicados en un buffer de 400 metros, es decir, 200 metros a lado y lado de la línea de borde de la ciudad. A cada uno de los predios se le analizaron 23 variables (10 continuas y 13 categóricas), mediante un análisis multivariado, el cual buscaba explicar el grado de relación existente entre estas y su correspondencia con la reglamentación del uso del suelo. Entre los principales resultados se evidencia que los predios rurales ubicados en el borde son cada vez más urbanos como consecuencia del tamaño de área, del valor del metro cuadrado del terreno, de su área construida y/o la afectación por amenazas de remoción en masa, situación que se manifiesta especialmente en las localidades de Usme, Ciudad Bolívar, Suba, Bosa y Usaquén. Se confirma que el avance de las características urbanas sobre el territorio rural de Bogotá es una realidad, pues las variables catastrales esperadas en los predios rurales (mayor tamaño, menor precio, menores áreas construidas, menores riesgos) adquieren características urbanas justo en las áreas de contacto, situación que no solo transforma el territorio, sino que consume los espacios rurales e introduce nuevos usos, propios de las ciudades. Se reflexiona sobre la necesidad de tener un instrumento de planeación para las áreas de borde urbano-rural, tal como se tiene para el territorio rural (unidades de planeamiento rural) o para el territorio urbano (unidades de planeamiento zonal).
Characteristics of genetic mineralogy of pyrite and quartz and their indicating significance in the Gaosongshan Gold Deposit, Heilongjiang Province, NE China
Authors: Geng Huiqing , Gu Xuexiang , Zhang Yongmei
Published: February 2019

The Gaosongshan epithermal gold deposit in Heilongjiang, Northeast China, is hosted by the Lower Cretaceous intermediate-basic volcanic rocks. Three auriferous quartz veins including eleven gold orebodies were all discovered in tectonoclastic zones. Genetic mineralogy study including the thermoelectricity, rare earth elements and trace elements of pyrite and rare earth elements of quartz were carried out. Thermoelectric conductive type of pyrite is mainly N-P type. Calculating the thermoelectric parameters XNP and denudation percentage γ of pyrites from orebodies 1-I, 2-II and 2-IV, suggests that gold orebodies are all eroded to their middle-lower parts. The variable range of Co concentrations (51.3-264.0ppm) and Ni concentrations (68.9-258.0ppm) and Co: Ni ratio (0.31-1.90), together with relatively small Sr/Ba ratio in ore-bearing pyrites (0.11-0.50), supports a hydrothermal origin of mineralization at Gaosongshan gold deposit. Compared with volcanic rocks, the chondrite-normalized REE patterns of ore-bearing pyrites and quartz are all LREE enriched with similar ΣLREE/ΣHREE ratio ranging from 7.37-13.68 in ore-bearing pyrites, 4.74-15.37 in ore-bearing quartz and no Ce anomalies. δEu values in ore-bearing pyrites and quartz are 0.65-1.66 (average=0.93) and 0.66-1.62 (average=1.03), respectively. δEu values of volcanic rocks are 0.86­1.07 (average 0.94), suggesting no obvious negative Eu anomalies. Similar REE characteristics of ore-bearing pyrites and quartz and volcanic rocks, together with previous oxygen and hydrogen isotope studies of quartz, suggest that the ore-forming fluids of the Gaosongshan gold deposit were mainly magmatic origin which was associated with andesitic magma and was partly mixed with atmospheric water. Comparing trace elements characteristics of ore-bearing pyrites with volcanic rocks, together with previous S isotopic studies, it is concluded that the ore-forming materials were derived from the surrounding rocks. Slight changes of Y/Ho (23.80­27.28), Zr/Hf (35.41­47.83), Nb/Ta (10.96­18.52) in ore-bearing pyrites indicate that the ore-forming fluid system is relatively stable during the ore-forming process.
Full waveform inversion in time and frequency domain of velocity modeling in seismic imaging: FWISIMAT a Matlab code
Authors: Singh Sagar , Kanli Ali Ismet , Mukhopadhyay Sagarika
Published: February 2019

This paper investigates the capability of acoustic Full Waveform Inversion (FWI) in building Marmousi velocity model, in time and frequency domain. FWI is an iterative minimization of misfit between observed and calculated data which is generally solved in three segments: forward modeling, which numerically solves the wave equation with an initial model, gradient computation of the objective function, and updating the model parameters, with a valid optimization method. FWI codes developed in MATLAB herein FWISIMAT (Full Waveform Inversion in Seismic Imaging using MATLAB) are successfully implemented using the Marmousi velocity model as the true model. An initial model is obtained by smoothing the true model to initiate FWI procedure. Smoothing ensures an adequate starting model for FWI, as the FWI procedure is known to be sensitive on the starting model. The final model is compared with the true model to review the number of recovered velocities.

Juventudes e educação: invisibilidades e emergências no percurso histórico brasileiro
Authors: Barros Lucian Da Silva
Published: February 2019

O objetivo deste artigo é discutir a temática das juventudes e sua relação com a educação, adotando como recorte as concepções existentes a respeito desse período da vida no percurso histórico brasileiro. Como metodologia optou-se pela revisão da literatura, com o levantamento de pesquisas e discussões correlatas. Após a análise levantou-se a discussão de que, embora os jovens apareçam na cena social, eles são sempre vistos (ou quase não vistos) como sujeitos incompletos, imaturos irresponsáveis e, assim, desacreditados. São nomeados genericamente, o que torna ausente suas diferenças, divergências e multiplicidades. Considerou-se que um trabalho de percepção das diversidades (conhecimentos, tempo linguagens) que ultrapasse as noções universais descritas para os jovens é necessário para fazer emergir novas concepções que possibilitem a juventude brasileira ser sujeito de sua própria história. A educação e a escola, ao passo que reproduzem o modelo e a visão fragmentada desse período da vida, também são capazes de contribuir para a construção de novos significados do ser jovem, nos quais a diferenças e a alteridade sejam valorizados. Nesse campo a ação educativa assume importante papel, pois possibilita a ressignificação da concepção social a respeito da juventude, produzindo novos sentidos que deem lugar à transformação social.
Batas Hak Suami dalam Memperlakukan Istri Saat Nusyuz dan Sanksi Pidananya
Authors: Saoki Saoki
Published: February 2019

This study wants to answer two problems: first, the limit where the husband’s rights treat his nuzuz wife; and second, the provision of criminal sanction for the husband who goes beyond the limit of such rights. This research uses the normative research approach. Hopefully, through this approach it can be seen the limit of the husband’s rights in threatening his nuzuz wife and the criminal sanction for the husband who goes beyond the limit of such rights. The result of the research concludes that Islam gives the boundary to the husband’s rights toward his nuzuz wife: first, the persuasive right and physical sanction through the media of mentoring. The next step is through ‘bed separation’ and then physical sanction in the way of beating that does not hurt and injure; second, the right not to give the maintenance; and third is a divorce right. The husband’s action in implementing his rights that exceeds the limit of physical sanctions such as physical violence to hurt, injure, and harm, or psychological violence such as intimidation that causes severe trauma, according to KUHP and Undang-Undang no. 24 tahun 2004, can be subject to criminal sanction.
[Studi ini ingin menjawab dua permasalahan. Pertama, Sampai di mana batasan hak-hak suami dalam memperlakukan istri yang nusyuz. Kedua, bagaimana ketentuan sanksi pidana bagi suami yang melampaui batas-batas haknya tersebut. Penelitian ini menggunakan pendekatan (teori) normatif research. Diharapkan melalui pendekatan ini dapat diketahui batasan hak-hak suami dalam memperlakukan istri yang nusyuz dan sanksi pidana bagi suami yang melampaui batas-batas haknya. Hasil penelitian menyimpulkan bahwa Islam memberi batasan hak suami pada istri yang sedang nusyuz; pertama, hak persuasif dan sanksi fisik melalui tahapan pemberian nasehat, lalu tahap berikutnya melalui pisah ranjang, lalu kemudian sanksi fisik melalui cara memukul yang tidak sampai menyakiti bahkan mencederai atau melukai, yang bersifat mendidik dan memberi pelajaran. Kedua, hak tidak memberi nafkah, dan ketiga hak talak. Tindakan suami dalam menggunakan hak sanksi fisik yang melebihi batas seperti adanya kekerasan fisik yang menyakiti, melukai atau mencederai, atau kekerasan psikis seperti intimidasi yang menimbulkan trauma berat, menurut KUHP dan UU No. 23 Tahun 2004, tindakan suami tersebut dapat dikenai sanksi pidana.]
‘Iddah Dan Ihdad Bagi Wanita Karir
Authors: Susilo Edi
Published: February 2019

The concept of ‘iddah and ihdad in Islamic jurisprudence that has been running so far requires women to shy away from the social interaction and the avoidance of activities that may attract the attention of men, such as preening, ornate, and so on. They are regarded to mediate the appearance of the prohibited wedding on the waiting period („iddah). It is very collide with the present fact about the career women which demand them to work hard, always look attractive, and keep the interaction with the opposite sex. These factors encourage them to have an outdoor activity to support their financial result and career. The clash between the concept of fiqh and the current condition of the career women becomes the object of the discussion. Consideration that can change the legal status of ‘iddah and ihdad when collides with the issue of career women is a consideration hajah and darurah. In addition, the legal settlement of the career women can be said to be more applicable, effective, and humane. This paper will examine about ‘iddah and ihdad for the career women through the lens of maqasid al-shari’ah so the concept of Islamic jurisprudence can still be applied in contemporary era without negating the rights of the individual and social.
[Konsep ‘iddah dan ihdad dalam fiqh yang telah dijalankan selama ini, mengharuskan wanita untuk menghindar dari interaksi sosial serta menghindar dari aktifitas yang dapat menarik perhatian laki-laki, semisal bersolek, berhias, dan sebagainya karena dianggap dapat menjadi perantara munculnya pernikahan pada masa ’iddah yang hukumnya dilarang. Hal ini sangat berbenturan dengan fakta kekinian tentang wanita karir yang menuntut wanita bekerja ekstra untuk memenuhi kebutuhan hidup yang mengharuskan wanita ini untuk selalu berpenampilan menarik serta menjaga interaksi dengan siapapun termasuk lawan jenis sehingga tertuntut untuk selalu beraktifitas keluar rumah, hal ini ditujukan untuk menunjang hasil finansial dan karirnya. Dua fakta mengenai benturan konsep fiqh dengan kondisi kekinian yang dalam hal ini adalah wanita karir, menjadi objek pembahasan yang menarik untuk kemudian dicarikan solusinya. Pertimbangan yang dapat merubah hukum ‘iddah dan ihdad ketika berbenturan dengan masalah wanita karir adalah pertimbangan hajat dan d}arurat mengingat efektifitas hajat dan d}arurat sehingga penyelesaian hukum „iddah dan ihdad bagi wanita karir dapat dikatakan lebih aplikatif, efektif dan humanis untuk era kekinian dengan pertimbangan hajat dan darurat. Tulisan ini akan mengkaji tentang ‘iddah dan Ihdad Bagi Wanita Karir melalui kacamata maqasid ash-Shari’ah sehingga konsep fiqh masih dapat diaplikasikan di era kekinian tanpa meniadakan hak-hak individu dan sosial.]
Makna Kedewasaan dalam Perkawinan
Authors: Gufron Muhammad
Published: February 2019

In a marriage, the bridegroom’s maturity is one of the considerations of many parties especially for the state official. Maturity should be owned by each spouse since it is deemed necessary to determine the happiness of the family. However, in term of law itself provides many different provisions concerning with the minimum age of consent, it has no mutual understanding about the agreed boundary between one law and another. Because of that, this paper further examines the meaning of maturity according to law and custom. The study is carried out to find the meaning of maturity in a marriage that is expected to contribute to the policy makers of law. Because of that, the author uses a juridical, philosophical, and sociological perspective in viewing the meaning of maturity in a marriage. Legally, a person can perform the marriage if his/her age has already reached the limit prescribed by law. In sociological sense, the bridegroom is supposed to understand the social responsibility. It can surely lead the family to the goodness and responsibility to community at large in maintaining peace through household. While the philosophical aspect of maturity hopes that the bridegroom is quite ready to face the challenge. In addition, it is expected that the emerging wisdom of the maturity can help to illuminate and make everything in their life as a lesson for the next action
[Dalam suatu perkawinan, kedewasaan para mempelai menjadi salah satu pertimbangan banyak pihak, terutama penyelenggara negara. Kedewasaan pasangan dipandang perlu dimiliki setiap pasangan yang hendak menikah karena nantinya akan menentukan kebahagiaan rumah tangga. Namun, dari sisi undang-undang sendiri, banyak memberikan ketentuan yang berbeda-beda tentang batas usia dewasa, tidak ada kesepakatan batasan antara undang-undang yang satu dengan yang lain. Untuk itu, tulisan ini mengkaji lebih jauh makna kedewasaan itu dengan melihat makna kedewasaan menurut undang-undang dan adat masyarakat. Telaah ini dilakukan untuk menemukan makna kedewasaan dalam perkawinan sehingga diharapkan dapat memberi sumbangan kepada pembuat kebijakan perundang-undangan. Karena itu, penulis menggunakan perspektif yuridis, filosofis, dan sosiologis dalam melihat makna kedewasaan dalam perkawinan. Secara yuridis, Seseorang dapat melaksanakan perkawinan apabila usianya telah mencapai batas-batas yang telah ditentukan oleh undang-undang perkawinan. Kedewasaan dalam arti sosiologis menghendaki agar mempelai paham seutuhnya tanggung jawab sosial. Tentunya dapat membimbing keluarga pada kebaikan dan bertanggung jawab terhadap masyarakat secara luas dalam memelihara ketentraman melalui rumah tangga. Sedangkan kedewasaan dalam aspek filosofis mengharapkan agar para mempelai menjadi pribadi yang utuh dalam menghadapi tantangan hidup dalam rumah tangga, baik yang bersifat semu maupun nyata. Selain itu, diharapkan pula kebijaksanaan yang muncul dari kedewasaan tersebut dapat membantu menerangi dan menjadikan segala hal dalam hidup sebagai pelajaran bagi setiap tindakan yang akan dilakukan selanjutnya.]
Flows of communication and ‘influentials’ in Twitter: A comparative approach between Portugal and Spain during 2014 European Elections
Authors: Amaral Inês , Zamora Rocío , Grandío María del Mar , Noguera José Manuel
Published: February 2019

The research about the concept of influence on Twitter is still underdeveloped. This work is a theoretical and empirical approach on how politicians are engaging with citizens and/or journalists, and how these social conversations are framed under specific topics and users. The idea of new influentials on political communication in the new media ecosystem, as some studies found (Dang-Xuan et al, 2013), can offer empirical pursuit of the suggested ‘two-step flow model’ as applied to the agenda-setting process (Weimann et al., 2007) in the case of the microblogging for campaigning online.
Following the recent research about how politicians try to reach their potential audience (Vaccari and Valeriani, 2013; 2013a), this paper analyses the social conversations on Twitter driven by politicians, the main topics in these political conversations and the kind of flows of communication (direct or indirect) between politicians, journalists and citizens. This research explores the differences and similarities about influence on Twitter during European elections in two countries with similar political and economic contexts: Portugal and Spain.
Identities in Flux: An Analysis to Photographic Self-Representation on Instagram
Authors: Caldeira Sofia P
Published: February 2019

Based on a review of literature and on a content analysis of nearly 12,000 photographs from 104 Instagram's users, this paper analyses the uses of photography as a self-representational device, comparing traditional vernacular usages with the new practices that emerged on Instagram. It seeks to understand the motivations underlying Instagram's uses, particularly focusing on its identitary functions, that helps to create visual self-representations in online environments. Identitary construction is understood as an active performance, in which each user is their own author, inventing and re-inventing themselves at each moment, in a continuous flux of imagetic creation that expresses a sense of identity open to constant reinvention. This paper explores not only the creation of selfies, a practice analogous to the self-portrait, but also the parallel strategies used to avoid the discomfort often caused by direct self-representation.
El debate de la actualidad periodística española en Twitter: Del corporativismo de periodistas y políticos al activismo ciudadano
Authors: López-Meri Amparo , Casero-Ripollés Andreu
Published: February 2019

La información periodística adquiere una nueva dimensión en redes sociales como Twitter. Desde esta plataforma, los ciudadanos debaten y condicionan asuntos hasta ahora reservados a los medios de comunicación. Los periodistas ya no se limitan únicamente a informar. Los políticos disponen de un nuevo canal para comunicarse directamente con los votantes. También los movimientos sociales aprovechan la viralidad de Twitter para denunciar los abusos cometidos por el poder. Para evaluar el alcance de estos cambios en el periodismo y la comunicación política, este artículo examina las estrategias que cada tipo de usuario despliega en Twitter, mediante las metodologías del análisis de contenidos y el estudio del encuadre aplicadas a los casos de #ArdeValencia (incendios forestales de Valencia) y #25N (elecciones de Cataluña). Ambos hashtags aluden a hechos ocurridos en España en 2012. Los resultados muestran que los actores tradicionales en la esfera pública, como periodistas y políticos, tienden a autopromocionarse sin interactuar con terceros, mientras que los colectivos ciudadanos parecen interesados en fiscalizar a la clase política, al menos durante las campañas electorales. Además, se advierte el uso partidista de la etiqueta #ArdeValencia para desacreditar al Gobierno valenciano.

El advenimiento de Internet y las herramientas de la web social ha propiciado cambios en las relaciones sociales; cambios a los que la Administración Pública no es ajena. .
En aras de una Administración más abierta, donde el ciudadano usuario de la red exige una participación más activa en la Res Pública, cobra sentido el concepto de transparencia. Una noción que propone una nueva relación entre la Administración y la ciudadanía.
El acceso a la información que posibilita Internet, no obstante, debe ser medible. En este sentido, la transparencia necesita parámetros y clasificaciones para su cuantificación o, al menos, posibilidad de ser medida villa kota bunga.
Estudio propone un ranking de trasparencia de los ayuntamientos con más de 30.000 habitantes de la Eurorregión Galicia - Norte de Portugal. Así, la muestra está conformada por un total de 44 websistes: 32 municipios lusitanos y 12 españoles.
La ficha de análisis valoró la información aportada sobre los miembros de la cámara y órganos de gobierno, información el propio ayuntamiento (con especial interés en la transparencia económica) y las formas de comunicación que ejerce la casa consistorial tanto en su website como en redes sociales.
El análisis se realizó durante el mes de marzo de 2015, periodo carente de comicios electorales en ambos países.
El resultado ha sido un ranking que permite comparar la transparencia de los ayuntamientos, desglosando las puntuaciones obtenidos en los apartados que conformaron la ficha de análisis.

Intergenerational and collaborative use of tablets: «in-medium» and «in-room» communication and interaction
Authors: Amaro Ana Carla , Oliveira Lidia , Veloso Ana Isabel
Published: February 2019

This study is anchored on two fundamental ideas: i) promoting intergenerational solidarity, relations and communication is a key factor for social development in an aging world; and ii) understand how different generations interact with and around digital media and technology is crucial to reconfigure design methods, so we may enhance intergenerational communication, learning and understanding. In particular, we aim to study how tablet’s devices and applications are jointly and collaboratively used by older adults/grandparents and (grand)children and the perceived impact that those interactions may have on: i) intergenerational relationships; ii) children and older adult’s digital literacy; and iii) attitude towards the other. For this purpose, semi-structured interviews and exploratory studies will be conducted, in the context of which «Joint Media Engagement» (Takeuchi & Stevens, 2011) sessions between selected cases of older adults and children (with and without parental relations) will be promoted, in order to observe, describe and characterize their «in-medium» (Takeuchi & Stevens, 2011) and «in-room» (Stevens, Satwicz & McCarthy, 2008) activities and interactions. We expect to be able to propose a set of guidelines for the design of contents for tablets, intended for intergenerational and collaborative use by older adults and/or grandparents and children and/or grandchildren.
A Construção Mediática da Corrupção Política. Opinião e Informação sobre os casos BPN, Freeport e Face Oculta nos noticiários televisivos portugueses
Authors: Figueiras Rita
Published: February 2019

Este artigo pretende contribuir para um melhor conhecimento acerca do modo como os comentadores abordaram nos noticiários televisivos do prime-time dos canais generalistas portugueses três dos casos de corrupção mais mediatizados nos últimos anos em Portugal: os casos BPN, Freeport e Face Oculta. Analisamos os temas, atores, tom e estilo dos comentários sobre os casos de corrupção e aferimos a conexão entre a narrativa do comentário e a da cobertura jornalística sobre os mesmos casos.

O estudo permitiu concluir que a cobertura noticiosa foi o expectável ponto de partida dos comentários, mas em sede da opinião identificámos a produção de uma narrativa muito diferente da noticiosa. Os comentadores ordenaram e relevaram os factos de modo distinto e construíram uma narrativa conflitual, consubstanciada em tons negativos sobre o que entenderam ser o comportamento desadequado dos atores envolvidos. Propuseram uma versão dos acontecimentos em cuja narração encontramos histórias personificadas sobre a luta de poder nas e entre as mais altas instâncias das esferas política, judicial e de regulação portuguesas.

No dia 12 de maio de 2016 o Senado Federal brasileiro aprovou a abertura do processo de impeachment contra a presidente da República, Dilma Rousseff. Os programas jornalísticos, que há meses faziam a cobertura da crise política, noticiaram os desdobramentos da histórica votação. Este artigo, que tem como objeto um desses programas – o Jornal Nacional, da Rede Globo – faz uma análise de conteúdo (Bardin, 1977) da edição apresentada no dia em que a presidente caiu. O objetivo geral é interpretar como o afastamento foi noticiado. O objetivo particular é analisar o telejornal à luz dos conceitos de jornalismo (Traquina, 2005), gêneros jornalísticos (Beltrão, 1969, 1976, 1980) e ética (Bucci, 2004).
El conflicto Palestino–Israelí en la prensa española: la cobertura de la Operación Margen Protector en ABC y La Vanguardia
Authors: Rodríguez Esperanza María-Soledad , Humanes María-Luisa
Published: February 2019

Durante el desarrollo de uno de los episodios del conflicto palestino – israelí tuvo lugar la Operación Margen Protector, que atrajo la atención de la prensa hacia uno de los conflictos internacionales más largos de la historia. Esta investigación se centra en la cobertura que dos periódicos españoles dedicaron a este hecho: ABC y La Vanguardia. A través un análisis de contenido cuantitativo se pudo analizar aspectos tales como la presencia y la relevancia que le otorgaron a la contienda, así como aspectos como la presentación de sus protagonistas y el uso de las fuentes.
Tras esto, se llegó a la conclusión de que, a pesar de pequeñas diferencias en el estilo de ambos medios, la cobertura y la relevancia fueron similares en ambas cabeceras.
Em busca do sentido da vida: a perspectiva de estudantes de Vedanta sobre “uma vida de yoga”
Authors: Bastos Cecilia
Published: February 2019

Resumo: Este artigo analisa os significados de se tornar devoto, segundo a tradição de ensinamento Vedanta, e algumas implicações decorrentes deste tipo de experiência vivenciada pelos interlocutores. Baseia-se no trabalho de campo realizado junto a um grupo de estudantes de Vedanta não dualista que vive na cidade do Rio de Janeiro. Os significados desse aprendizado serão retratados, assim como sua implicação sobre o estilo de vida do grupo. Além disto, questões como trajetória do indivíduo ocidental, desencantamento espiritual e perda fundamental do sentido de viver serão discutidas, com a finalidade de análise a respeito do tipo de religiosidade praticado pelo grupo pesquisado e, em última instância, de contribuir para o entendimento do(s) significado(s) de ser “religioso” ou “espiritualizado” na modernidade.
Posiciones discursivas sobre sexualidad, deseo y placer sexual en jóvenes estudiantes chilenos y mexicanos
Authors: Tinoco Karla Alejandra Contreras , Silva-Segovia Jimena
Published: February 2019

Resumen En este artículo buscamos comprender los significados sobre sexualidad, deseo y placer sexual de jóvenes heterosexuales, estudiantes, de entre 15 y 19 años, de Ocotlán, México y Antofagasta, Chile. Si bien geográficamente distantes, al estar situados en Latinoamérica, ambos emplazamientos comparten elementos socioculturales como: feminidad asociada al modelo mariano; cultura occidental de hegemonía masculina; procesos de colonización europea; religiosidad influyente en la familia y la vida sexual; y peso preponderante del neoliberalismo. La metodología fue cualitativa, con perspectiva pos/decolonial y feminista. La recolección de datos se efectuó con entrevistas y grupos de conversación. Realizamos análisis de inferencias discursivas. Entre los hallazgos, encontramos que en los dos contextos emergen posiciones discursivas de tipo esencialistas sexuales, sexistas, mercantilistas, románticas y contrasexuales.
“Eu tenho que te contar um negócio”: gestão da soropositividade no contexto dos relacionamentos afetivo-sexuais de jovens vivendo com HIV
Authors: Agostini Rafael , Maksud Ivia , Franco Túlio
Published: February 2019

Resumo Com o avanço da terapêutica, crianças infectadas pelo HIV começaram a chegar à adolescência e a se relacionar afetiva e sexualmente. O diagnóstico, no entanto, torna-se um marco na trajetória dos sujeitos, estabelecendo novas teias de relações e processos sociais. Neste trabalho buscamos refletir - a partir de uma perspectiva socioantropológica - sobre discursos e práticas (re)produzidos e agenciados por jovens infectados pelo HIV por transmissão mãe-bebê na gestão de sua condição sorológica no contexto dos relacionamentos afetivo-sexuais. Partindo da construção de narrativas através de entrevistas abertas, analisamos os significados atribuídos à convivência com a doença na vida cotidiana, com ênfase na importância do vínculo no processo de revelação, nas estratégias de (não) uso de preservativo e na preocupação de infectar outras pessoas. Trazemos também ao debate as preocupações quanto ao estigma, os planos para a vida reprodutiva e o lugar dos parceiros na gestão do cuidado.
Viewpoint: Human-in-the-loop Artificial Intelligence
Authors: Zanzotto Fabio Massimo
Published: February 2019

Little by little, newspapers are revealing the bright future that Artificial Intelligence (AI) is building. Intelligent machines will help everywhere. However, this bright future may have a possible dark side: a dramatic job market contraction before its unpredictable transformation. Hence, in a near future, large numbers of job seekers may need financial support while catching up with these novel unpredictable jobs. This possible job market crisis has an antidote inside. In fact, the rise of AI is sustained by the biggest knowledge theft of the recent years. Many learning AI machines are extracting knowledge from unaware skilled or unskilled workers by analyzing their interactions. By passionately doing their jobs, many of these workers are shooting themselves in the feet.

In this paper, we propose Human-in-the-loop Artificial Intelligence (HitAI) as a fairer paradigm for AI systems. Recognizing that any AI system has humans in the loop, HitAI will reward these aware and unaware knowledge producers with a different scheme: decisions of AI systems generating revenues will repay the legitimate owners of the knowledge used for taking those decisions. As modern Merry Men, HitAI researchers should fight for a fairer Robin Hood Artificial Intelligence that gives back what it steals.

Background

This study characterizes the tumor-immune microenvironment in pretreatment, localized anal squamous cell carcinoma (ASCC), including two markers that have not previously been studied in ASCC: indoleamine 2,3 dioxygenase 1 (IDO1) and human leukocyte antigen (HLA) class I.

Materials and Methods

Retrospective review identified 63 patients with ASCC receiving definitive chemoradiation between 2005 and 2016 with pretreatment tissue available. Immunohistochemistry was used to quantify cluster of differentiation 8 (CD8), programmed cell death protein 1, programmed death-ligand 1, HLA class I, and IDO1. Cox proportional hazards models evaluated associations between outcomes and immune markers, controlling for clinical characteristics.

Results

With a median follow-up of 35 months, 3-year overall survival was 78%. The only marker found to have a robust association with outcome was tumor IDO1. In general, the percentage of tumor cells expressing IDO1 was low (median 1%, interquartile range 0%–20%); however, patients with >50% of tumor cells expressing IDO1 had significantly worse overall survival (hazard ratio [HR] 4.7, p = .007) as well as higher local recurrence (HR 8.6, p = .0005) and distant metastasis (HR 12.7, p = .0002). Tumors with >50% IDO1 were also more likely to have the lowest quartile of CD8 infiltrate (<40 per high-power field, p = .024).

Conclusion

ASCC has a diverse immune milieu. Although patients generally do well with standard therapy, IDO1 may serve as a prognostic indicator of poor outcome and could help identify a patient population that might benefit from IDO-targeted therapies.
Seismic performance of infilled RC frames with steel corrugated shear walls
Authors: Feng Ningning , Wu Changsheng , Cao Pingzhou
Published: February 2019

This paper presents experimental and analytical investigations of infilled reinforced concrete (RC) frames with steel corrugated shear walls. In the experimental study, two 1/3-scale, one-bay, two-storey specimens were constructed and tested under cyclic load reversals. One specimen was bare, for comparison. Properties affecting seismic performance, such as strength and stiffness of the two specimens, were investigated. However, owing to the inherent complexity of the infilled RC frame and the unique features of the steel corrugated shear walls, the experimental investigation was not sufficient to fully explain the influence of several parameters. Therefore, an analytical investigation based on finite-element models using ANSYS was conducted. Validation of the finite-element models against the experimental results showed good agreement. Critical parameters influencing the behaviour of steel corrugated shear walls, such as thickness and orientation of corrugated sheets, were varied, and the effects on seismic behaviour discussed.
Trade Exposure and the Evolution of Inflation Dynamics
Authors: Gilchrist Simon , Zakrajsek Egon
Published: February 2019

The diminished sensitivity of inflation to changes in resource utilization that has been observed in many advanced economies over the past several decades is frequently linked to the increase in global economic integration. In this paper, we examine this "globalization" hypothesis using both aggregate U.S. data on measures of inflation and economic slack and a rich panel data set containing producer prices, wages, output, and employment at a narrowly defined industry level. Our results indicate that the rising exposure of the U.S. economy to international trade can indeed help explain a significant fraction of the overall decline in responsiveness of aggregate inflation to fluctuations in economic activity. This flattening of the U.S. Phillips curve is supported strongly by our cross-sectional evidence, which shows that increased trade exposure significantly attenuates the response of inflation to fluctuations in output across industries. Our estimates indicate that the inflation-output tradeoff is about three times larger for low-trade intensity industries compared with their high-trade intensity counterparts.
Cuidado de crianças em acolhimento institucional: relações afetivas e dimensão temporal
Authors: Lemos Isabela Cristina , Da Silva Roselaine Berenice Ferreira
Published: February 2019

O presente artigo parte de uma pesquisa qualitativa que objetivou conhecer a relação da profissional cuidadora com os bebês e as crianças pequenas que se encontram em uma instituição de acolhimento localizada no interior do Rio Grande do Sul. Procurou-se enfocar as percepções das profissionais sobre o seu trabalho com bebês e crianças pequenas, em relação aos aspectos afetivos e do cuidado. Os instrumentos utilizados foram as entrevistas semiestruturadas com as cuidadoras que trabalham com a faixa etária do zero aos três anos e observações do cotidiano institucional. Os dados coletados foram analisados pela análise de conteúdo sendo construídas duas categorias de análise. A primeira aponta para um aspecto da relação evidenciado pelas cuidadoras, as rupturas frequentes e a percepção de fracasso, no que diz respeito a sua relação com os bebês e crianças pequenas. Aponta-se um possível sofrimento emocional nessas profissionais e enquanto possibilidade de defender-se apresentam atitudes mais distantes afetivamente. Esse outro ponto é discutido na segunda categoria, que expõem questões da dimensão temporal e das impossibilidades percebidas pelas profissionais frente ao estabelecimento de relações mais próximas com os bebês e crianças pequenas. Entretanto, outras falas sugerem possibilidades no cotidiano do abrigo nos momentos em que as cuidadoras conseguem reconhecer singularidades de cada bebê e criança pequena dentro deste contexto coletivo de cuidado. Aponta-se a importância de seguir pensando e refletindo nesses encontros que acontecem nas instituições de acolhimento, para que estes sejam marcados por relações afetivas significativas e de qualidade.
