Perceptions of the Diabetes Online Community’s Credibility, Social Capital, and Help and Harm: Cross-Sectional Comparison Between Baby Boomers and Younger Adults
Authors: Litchman Michelle L , Edelman Linda S
Published: April 2019

Background

The use of online health communities such as the diabetes online community (DOC) is growing. Individuals who engage in the DOC are able to interact with peers who have the same medical condition. It is not known if older adults are perceiving the DOC differently compared with younger adults.

Objective

The purpose of this study was to explore and understand how the DOC is perceived in terms of social capital, source credibility, and help and harm. The findings from this study will shed light on how users of different age groups (baby boomers and younger adult counterparts) perceive DOC use.

Methods

This study represents a subset of participants from a larger study of DOC users. Baby boomers and younger adults with diabetes were recruited from the DOC to participate in a cross-sectional survey. Demographics, electronic health use (reasons to join the DOC, DOC intensity, DOC engagement, internet social capital, and help or harm from the DOC), source credibility, health-related quality of life, and diabetes self-care data were collected. We examined the differences between baby boomer and younger adult responses.

Results

The participants included baby boomers (N=76) and younger adult counterparts (N=102). Participants scored their diabetes health care team (mean 33.5 [SD 8]) significantly higher than the DOC (mean 32 [SD 6.4]) with regard to competence (P<.05) and trustworthiness (diabetes health care team mean 36.3 [SD 7.1]; DOC mean 33.6 [SD 6.2]; P<.001). High bonding and bridging social capital correlated with high DOC intensity (r=.629; P<.001 and r=.676; P<.001, respectively) and high DOC engagement (r=.474; P<.01 and r=.507; P≤.01, respectively). The greater majority (69.8%) reported the DOC as being helpful, and 1.8% reported that the DOC had caused minor harm. Baby boomers perceived DOC credibility, social capital, help, and harm similarly to their younger adult counterparts.

Conclusions

Baby boomers are using and perceiving the DOC similarly to younger adults. DOC users find the DOC to be credible; however, they scored their health care team higher with regard to competence and trustworthiness. The DOC is beneficial with low risk and may augment current diabetes care.
Transformasi Kultural Menuju Demokrasi Substansial

“ Demokrasi diyakini telah membawa perubahan politik dan kultural. Namun, sebenarnya masyarakat telah mempunyai tradisi yang sesuai dengan prinsip demokrasi tersebut. Nilai-nilai demokrasi seperti menghargai pendapat orang lain, toleransi, dan keterbukaan, terus hidup laten di kalangan akar rumput. Kondisi tersebut menunjukkan potensi akar rumput sebagai agen pembaruan menuju masyarakat transformatif secara kultural ke arah demokratisasi sepertinya jauh lebih besar, dibandingkan dengan kelas menengah. Ini artinya, budaya politik kalangan akar rumput yang bertingkah laku politik yang bersih justru perlu ditiru oleh kalangan elite politik. Tingkah laku politik yang bersih akan menghasilkan budaya politik yang menjunjung tinggi nilai kejujuran sebagaimana yang ditunjukkan oleh kalangan akar rumput pada level komunitas RT-RW justru perlu ditiru oleh elite politik pada level politik nasional.”Kata Kunci: transformasi, agen, akar rumput

“ Pancasila sebagai dasar negara telah mendapat tempat di hati para pemimpin bangsa ini. Sebaliknya, pancasila belum mendapat tempat dalam kehidupan bersosial dan berpolitik bangsa ini. Konflik sosial, politik masih terjadi dibawah kepakan sayap Pancasila, masalah muncul ketika Pancasila dipahami sebagai instrumen negara, tetapi belum menjadi paham negara. Hal ini ditunjukkan dengan berbagai ritualitas Pancasila yang belum menyentuh keyakinan berbangsa dan bernegara masyarakat. Oleh sebab itu, diperlukan upaya menggeser pemahaman Pancasila dari bentuk instrumental dengan sekadar menghafal sila Pancasila, menuju bentuk kontestasi dengan terlibat dalam “arena” Pancasila.’Kata Kunci : Pancasila, Ideologi, Kontestasi, Cultural Studies
Membaca Ulang Kultur Kepolisian Negara Republik Indonesia (Sebuah Refleksi Kritis Dari Dalam)
Authors: Ratmono Barito Mulyo
Published: April 2019

Pelekatan stigma terhadap kultur Polri oleh masyarakat masih terjadi, meskipun telah dilakukan reformasi struktural dan instrumental. Polri kerap memperdebatkan bahwa bukan kultur organisasinya yang tidak baik, melainkan ada sebagian aktor Polri yang memiliki perilaku bertentangan dengan nilai, norma, dan simbolisasi normatif kultur Polri (Tri Brata dan Catur Prasetya). Namun perilaku tersebut terus menerus diproduksi melintasi ruang dan waktu sehingga mereproduksi struktur yang merupakan metafora dari kultur Polri yang tidak baik.Penelitian dilakukan sejak Februari 2011 sampai Oktober 2012 dengan menggunakan pendekatan kualitatif dan metode etnografi kritis, yaitu mengeksplorasi fenomena sosial melalui penyajian bentuk-bentuk kontradiksi dari berbagai gagasan serta aktivitas yang mengkonstruksi kultur Polri saat ini. Informan yang dilibatkan sebanyak empatpuluh satu orang meliputi empat wilayah penelitian, yaitu: Mabes Polri, Akademi Kepolisian, Sekolah Polisi Negara Purwokerto, dan Polda Jawa Tengah. Data pendukung diperoleh dari foto, film, dokumen sejarah Polri, serta kliping koran yang memuat pemberitaan Polri (2009-2011). Data dikumpulkan melalui wawancara mendalam, pengamatan kegiatan pendidikan di Akpol dan SPN serta kegiatan kepolisian di jajaran Polda Jawa Tengah. Teori yang digunakan terdiri dari teori strukturasi (Giddens), teori hegemoni (Gramsci), dan teori kritis self reflextion (Habermas).Ada tiga temuan dari hasil penelitian: (1) konstruksi struktur kultur organisasi tidak dilaksanakan dengan baik di pabrik aktor Polri dengan indikasi adanya kebijakan memutasikan aktor yang menyimpang ke pabrik aktor Polri, fenomena kontradiksi posisi aktor pendidik, konfigurasi pengetahuan profesionalisme tugas lebih banyak terdapat dalam narasi kurikulum dibandingkan gugus pengetahuan kultur normatif Polri, ada beberapa perkataan di lembaga pendidikan pembentukan yang memiliki makna tertentu dan dapat mempengaruhi kesadaran para calon aktor dalam memunculkan gagasan dan perilaku sebagai aktor Polri; (2) ada praktik hegemoni absolut dan hegemoni ala Gramsci dalam relasi antar aktor Polri yang bertarung dalam arena praktik-praktik kepolisian; dan (3) adanya struktur pertarungan kepentingan dan motivasi dalam konstruksi kultur Polri, yaitu pertarungan gagasan dan tindakan yang sesuai dan tidak sesuai dengan nilai, norma, dan simbolisasi normatif Polri.Disimpulkan bahwa belum membaiknya kultur Polri hingga saat ini dikarenakan telah ada proses produksi yang cacat di pabrik aktor Polri, adanya penyalahgunaan jabatan dan kewenangan melalui proses hegemoni serta pertarungan kepentingan antar aktor Polri. Oleh karena itu, direkomendasikan perubahan kultur Polri harus dimulai dari lembaga pendidikan dan satuan kewilayahan secara bersamaan melalui proses hegemoni untuk menanamkan gagasan dan tindakan yang sesuai dengan nilai, norma, dan simbolisasi normatif kultur Polri.
Transformasi Habitus Pada Komunitas Penerima Zakat
Authors: Puspitasari Dewi Cahyani
Published: April 2019

Pengelolaan zakat yang dilakukan oleh organisasi pengelola zakat (OPZ) mengalami transformasi signifikan sejak pengelolaan zakat tahun 1990-an. Kondisi ini berupa pola distribusi zakat beralih dari ranah amal sosial keagamaan menuju ranah pemberdayaan pengembangan ekonomi. Penelitian ini bermaksud melihat dan memetakan kecenderungan 2 (dua) OPZ dalam mengimplementasikan program pendampingan zakat produktif. Setelah memetakan posisi kedua OPZ tersebut dapat diperoleh deskripsi pola pendampingan yang mengacu pada interpretasi lembaga mengenai zakat produktif. Hasil penelitian menunjukkan bahwa mekanisme transformasi habitus diperoleh dari kegiatan pendampingan yang dilakukan OPZ pada komunitas penerima zakat (dhuafa). Dari pola pendampingan inilah yang kemudian dhuafa melakukan reproduksi pengetahuan dan reproduksi habitus untuk memunculkan praktik sosial berupa ‘habitus baru’. Bentuk habitus baru ini ada pada 2 (dua) aspek yaitu habitus zakat dan habitus produktif. Implikasi transformasi habitus ini masih dominan pada level individu belum pada level kelompok (komunitas). Adanya transformasi habitus tersebut juga berimplikasi pada kondisi kemandirian komunitas.Kata-kata Kunci : Organisasi Pengelola Zakat (OPZ), Transformasi Habitus dan Pendampingan Komunitas .
Konstruksi Media Terhadap Perempuan Terlibat Kasus Korupsi dalam Tayangan Televisi

Published: April 2019

Artikel ini memfokuskan pada konstruksi media-televisi terhadap perempuan yang terlibat kasus tindak pidana korupsi. Dalam sepuluh tahun terakhir fenomena perempuan masuk dunia politik pemerintahan semakin meningkat, tetapi sekaligus juga diikuti oleh semakin banyaknya perempuan yang terjerat perkara korupsi. Pertanyaan pokok yang ingin dijawab dalam penelitian ini adalah bagaimana media massa mengkonstruksi perempuan terlibat korupsi melalui produksi dan reproduksi wacana yang dilakukan lewat ekspose pemberitaannya. Studi ini menggunakan metode analisis wacana kritis dari Norman Faircloug. Konstruksi media terhadap perempuan terlibat korupsi lebih banyak dibelokan ke isu irotis, domistik, dan suka glamour, bukan pada substansi masalah korupsi itu sendiri. Proses domestikasi oleh media ini mengindikasikan bahwa di ranah politik masih merupakan ranah laki-laki. Konteks sosial budaya akan fenomena tersebut merujuk bahwa dalam masyarakat ternyata masih patriarkis, sehingga jika ada perempuan aktivis politik mengalami kasus politik, media pun kemudian mengkonstruksi perempuan tidak beranjak dari sektor domistik. Produksi wacana seperti itu terus-menerus dilakukan televisi, terlebih lagi ketika mengambil momentum perempuan yang terkena kasus tindak pidana korupsi. Implikasi lebih lanjut, televisi semakin menegaskan dan meneguhkan bahwa ranah politik bukanlah ranah perempuan, melainan laki-laki.

Published: April 2019

Consumer interest in the source of their food, its environmental footprint, and the impact of diet on health has supported the growth of the grass-finished beef (GFB) industry. Studies have concluded that GFB has distinct nutritional differences from conventionally-finished beef. As the GFB industry continues to expand, it is vital to continue to explore the nutritional complexities and variation in the product. To achieve this, a survey of grass-finishing production systems throughout the USA was conducted, and beef finished on the participating farms was analyzed for its nutritional composition, including fatty acid (FA), mineral and fat-soluble vitamin contents. Samples were analyzed from 12 producers and annual production capacity of farms ranged from 25 to 5,000 cattle, with a mean age of cattle at harvest of 26.8 ± 2.30 mo. An array of finishing diets included grazing exclusively in perennial pasture, incorporating annual forage crops, and feeding a variety of harvested forages with supplementation of non-starch feed byproducts. Beef muscle tissue FA content was analyzed by gas chromatography-mass spectrometry (GC–MS). The mean ratio of omega-6 (n-6) to omega-3 (n-3) FA in samples varied significantly by producer, ranging from 1.80 to 28.3 (P < 0.0001), with an overall sample set median of 4.10. A selection of minerals including iron, magnesium, and potassium were analyzed by ICP emission spectroscopy and mineral content significantly differed by producer for all minerals (P < 0.001). Mean α-tocopherol and β-carotene content was 610.6 µg/100 g beef and 32.2 µg/100 g, respectively. The amount of these antioxidants also varied between producers (P < 0.0001), but tended to be greater in beef finished solely on fresh forages. This survey indicates that commercially available GFB can vary in nutritional composition due to the diverse practices used to grass-finish cattle.

Published: April 2019

En la región central de México existen zonas con extensos afloramientos de rocas calcáreas plegadas formando sistemas montañosos con intenso desarrollo cárstico. El abastecimiento de agua en esta región se logra en una parte importante de acuíferos controlados por el sistema cárstico. Aquí se analiza el flujo subterráneo entre la localidad Joya de Luna (en una parte elevada de montaña) y Guaxcamá topográficamente más baja, para determinar si existe conexión entre ambas zonas y comprobar si el agua infiltrada en la parte alta se capta en la parte baja en aprovechamientos como manantiales. Se propone un método novedoso para identificar la conectividad hidráulica entre la zona de recarga y de descarga en un sistema cárstico y fracturado utilizando granos de polen como trazadores, denominada Metodología Polínica Ambiental (MEPAM). Para contrastar y examinar la viabilidad de este método se emplearon datos isotópicos de deuterio y oxígeno-18; se empleó además el exceso de deuterio como un factor para el análisis hidrogeológico. Se documentó el tipo de familias o especies existentes en la zona de recarga Joya de Luna y en la zona de descarga en Guaxcamá, mediante la colecta de polen directamente de la flor en un radio de 5 km con respecto a cada punto de muestreo de agua de las zonas de recarga-descarga y se generó una base de datos con 41 especies polínicas para la caracterización morfológica. Posteriormente se hizo una recolecta de 135 muestras de agua subterránea con granos de polen suspendidos en cinco norias en la zona de recarga y diez manantiales en la zona de descarga. El análisis de especies mostró que granos de polen de las especies de Zea mays, Avena sativa, Cicer arietinum y Quercus sp., característicos solo de la zona de recarga, se presentaban en las muestras de agua de la zona de descarga. Los resultados polínicos fueron congruentes con los obtenidos a partir de datos isotópicos y permitieron identificar dos rutas con conexión hidráulica, denominadas G1 y G2. Para cada una de estas rutas se estableció la conexión hidráulica entre muestras de la zona de recarga y muestras de la zona de descarga. En ambas zonas se presentaron granos de Zea mays, Avena sativa, y Cicer arietinum. El polen de la familia Quercus sp., propio de la zona montañosa, se detectó en las muestras de tres puntos de la zona de recarga y siete puntos de la zona de descarga.
A study on Moscow region sand pits’ plants properties for the restoration of sand pits vegetation
Authors: Dabbagh Alaa
Published: April 2019

Processes of plant regeneration and restoration of destroyed ecosystems, naturally occurring, in such areas are very slow. Considering sand pits as a man-made form of relief necessitates a comprehensive study of the features of sand pits vegetation, which helps stop the movement of sandy slopes, stabilize sands, and land reclamation. We have studied the slopes of the northern and southern exposition in some sand quarries (Zvenigorodsky, Dzerzhinsky, Ramensky (GOK), Lytkarinsky, Lyzlovo). Geobotanical descriptions, performed according to a standard method on the experimental areas of 5×5 square meters, are the basis of our work. The article shows that all the 93 species which we have found in the surveyed area were species of vascular plants. In this case the number of species is not only determined by the smooth running development of the landscape (taking into account the fact that the interference was rude and had a man-made factors), but by other factors such as steep slopes, light, moisture, and richness of the soil. The projective cover of sand pits constitutes 20-30 % which, in general, is a typical characteristic of sandy terrain [3]. Plants overwhelming majority in the spectrum of life forms according to K. Raunkiaer, are Hemicryptophytes, which is typical for the phytocoenosis of the Central Russia. It can be noted that the Chamaephytes are absent in most quarries, except for Dzerzhinsky. According to the classification of life forms by I.G. Serebryakov, sand slopes are dominated by herbaceous perennial polycarpics, among which long and short rhizome plants and tap rooted plants are in majority. Meadow plants are dominant in ecological-coenotic group. This group consists of fully developed plants, only, under conditions of good lighting. The rate of adventive species is low.

Authors: Sukiasyan Astghik Rafikovna
Published: April 2019

The antioxidant activity of an annual plant Maize Zea of the Armenian population, which grew in various soil-climatic regions of Armenia, was studied. Antioxidant activity by four biochemical parameters was evaluated, the quantitative changes of which under conditions of simulated drought (mild and severe) were determined. Maize Zea of the inbred line B73 was used as the biological control in the experiments. During the experiments, it was found that the Hushakert plant samples have an increased concentration of malonic dialdehyde and flavonoids. In the biological material of corn from Teghut, high concentration values for the restoration of iron and polyphenols by antioxidants are established. The increase in drought from a moderate to the severe biological control of B73 as well as from Armenian maize samples caused the activation of an antioxidant protection system in all four indices was established. This makes it possible to expand the use of maize as a plant indicator, and can be considered as functional foods, as they are a good source of natural antioxidants.

Experimentally determining the effects of water droplets collision when mixing aerosol with gas flow at different heating temperatures
Authors: Vysokomornaya Olga , Shlegel Nikita , Strizhak Pavel
Published: April 2019

The article presents the results of experimental studies of the collisions characteristics for water droplets in an aerosol at its entry into the air counter flow. The temperature of the latter ranged from 20?C to 500?C. Experiments were also carried out with the flow of combustion products having a temperature of 800- 850?C. The initial dimensions (radii) of the droplets in the aerosol were 50-1000 ?m. Visualization of the droplet motion in the counter flow of air and combustion products required the use of a hollow cylinder made of quartz glass with a height of 1 m and an internal diameter of 0.15 m, a cross-correlation complex and optical methods (particle image velocimetry, particle tracking velocimetry, interferometric particle imaging). The characteristics of the droplet interaction (size, velocity, total surface area of the liquid before and after) were controlled using a high-speed video camera and tracking algorithms in the TEMA AUTOMOTIVE software package. The main modes of drops interaction have been identified: bounce, coagulation, scatter, and breakup. The statistical information database has been obtained to describe the interaction modes using diagrams, taking into account the ratio of the sizes of colliding drops, velocities of their motion, and an angle between trajectories of motion. The influence of gas temperature on the probabilistic criteria of droplet collisions, as well as the integral criterion characterizing the change in the liquid surface area due to the intensification of droplet collisions in the gas medium has been established.

Published: April 2019

The moisture content of oil-filled transformers insulation paper that is a cellulose-containing material comprises 8% to 10% of moisture by weight at ambient temperature and it is highly important to decrease the moisture content for effective use of a transformer. Vapor phase drying is more effective method for drying the insulation paper of the transformer as compared with other conventional methods due to less cycle time and energy consumption. The purpose of this paper is to design a solvent operated drying chamber in which drying of the insulation paper of oil filled transformer carried out. The approach of the present paper is to develop a numerical model to reduce the cycle time of the drying process. The unsteady flow, heat, and mass transfer phenomena were simulated by using CFD solver. Theoretical studies and a numerical model were conducted over thermal calculation in the drying process using solvent at different pressures. Theoretical calculations were used to validate the numerical model. Drying chamber was optimized by using response surface methodology. The result of the study showed that drying cycle time was decreased almost 14.3% with the new design. Furthermore, when the solvent was used instead of air as a heat carrier, the drying cycle time was reduced.
Thermal properties of directionally oriented polymer fibrous materials as a function of fibre arrangement at mesoscopic level
Authors: Stankovic Snezana , Popovic Dusan , Poparic Goran
Published: April 2019

Thermal properties of directionally oriented fibrous materials have been investigated in this research with the purpose of considering the influence of fibre arrangement at mesoscopic level. The range of various distributions of fibres in the fibrous materials was obtained by applying different twist intensity during spinning of cotton fibres. From various twisted cotton yarns the knitted fabrics were produced under controlled conditions, so as to obtain as similar as possible constructions. This made possible to obtain the heterogeneity of the porous fibrous structures coming from the mesoscopic level. Thermal conductivity and heat transfer coefficient of the materials were investigated. The results obtained indicate the arrangement of fibres (or their compactness, orientation and migration), which, in turn, was determined by twist intensity (mesoscopic scale), as the key factor influencing thermal properties. Yarn compactness and fibre migration, determined by lateral forces imposed by the twist inserted in yarn, affected variations in structural parameters of the knitted fabrics, and thus influenced their thermal properties. Fibre orientation manifested itself in surface geometry of the yarn was also proved to have a considerable influence on heat transfer properties.
Magnetohydrodynamic free convection of non-Newtonian power-law fluids over a uniformly heated horizontal plate
Authors: Bahmani Alireza , Kargarsharifabad Hadi
Published: April 2019

The MHD free convection flow of non-Newtonian power-law fluids over a horizontal plate subjected to a constant heat flux is studied. The results are presented for various values of the three influential parameters, i. e. the generalized Hart?mann number, the generalized Prandtl number, and the non-Newtonian power-law viscosity index. Increasing the Hartmann number increases the thermal boundary-layer thickness and the surface temperature and consequently decreases the wall skin friction and Nusselt number. A lower generalized Prandtl number results in a larger skin friction coefficient and higher wall temperature as well as thicker thermal boundary-layer. The viscosity index is predicted to influence the flow conditions depending on the value of generalized Hartmann number. At high generalized Prandtl number numbers, by decreasing non-Newtonian power-law index, the wall skin friction, temperature scale, and thermal boundary-layer thickness are increased and the Nusselt number is decreased, while the opposite trend is observed for low generalized Prandtl number. A general correlation for the Nusselt number is derived using the numerical results
Thermal applications of hybrid phase change materials: A critical review
Authors: Tariq Syeda , Ali Hafiz , Akram Muhammad
Published: April 2019

Phase change materials (PCM) with their high latent heat capacity have a great ability to store energy during their phase change process. The PCM are renowned for their applications in solar and thermal energy storage systems for the purpose of heating and cooling. However, one of the major drawbacks of PCM is their low thermal conductivity due to which their charging and discharging time reduces along with the reduction in energy storage capacity. This reduction in the energy storage capacity of PCM can be improved by producing organic-inorganic hybrid form-stable PCM, with the combination of two or more PCM together to increase their energy storage capacity. Nanoparticles that possess high thermal conductivity are also doped with these hybrid PCM (HPCM)to improve the effectiveness of thermal conductivity. This paper presents a short review on the applications of HPCM in energy storage and building application. Apart from this a short section of applications of composite PCM (CPCM) is also reviewed with discussions made at the end of each section. Results from the past literature depicted that the application of these HPCM and CPCM enhanced the energy storage capacity and thermal conductivity of the base PCM and selection of a proper hybrid material plays an essential role in their stability. It is presumed that this study will provide a sagacity, to the readers, to investigate their thermophysical properties and other essential applications.
Wettability transition modes of aluminum surfaces with various micro/nanostructures produced by a femtosecond laser
Authors: Liu Weijian , Cai Mingyong , Luo Xiao , Chen Changhao , Pan Rui , Zhang Hongjun , Zhong Minlin
Published: April 2019

The wettability transition of hierarchical micro/nanostructure metal surfaces over time shows huge potential to fabricate the superhydrophilic and superhydrophobic surfaces without chemical coating. Although a large number of studies have reported the transition phenomenon on structured metal surfaces, the knowledge of which kind of micro/nanostructure contributes significantly to the acceleration or inhabitation of transition processes is still limited. In this article, the authors fabricated three kinds of typical micro/nanostructures with different topography features on aluminum surfaces by a femtosecond laser. The authors then systematically studied the relationship between the micro/nanostructures and the transition modes in ambient air. The results show that all structured surfaces show superhydrophilic nature initially but then become hydrophobic even superhydrophobic over time. The surfaces with regular microstructures hybrid with nanoripples and a few nanoparticles can achieve superhydrophobicity quickly, 27–30 days. Especially, these structures can realize superhydrophobicity within only 2 h if the low temperature heat treatment is performed on them in ambient air. In addition, the surfaces with regular deep microstructures hybrid with nanoripples and abundant nanoparticles can maintain superhydrophilicity for the longest time and show slow wettability transition mode due to the slower adsorption processes. These results may provide an aid to further understanding the wettability transition modes of different micro/nanostructures in ambient air and fabricating stable superhydrophobic and superhydrophilic surfaces without adding chemical coating.

Published: April 2019

Este texto visa compreender como os professores do ensino médio concebem a profissão docente, a partir de seu papel na (re) configuração do currículo escolar. As análises são resultados de uma pesquisa sobre a centralidade do papel dos professores no trabalho com jovens de uma escola de ensino médio na periferia do Rio de Janeiro. Os dados foram produzidos através da aplicação de questionários aos professores da escola (69) e aos alunos do último ano (341), realização de entrevistas gestores (4) e professores indicados pelos alunos (4), além de observação das aulas (60 horas). Compreende-se que as concepções dos professores sobre os objetivos do ensino médio direcionam a escolhas curriculares, orientam as suas práticas pedagógicas e (re) configuram a própria profissão. Identifica-se professores com novas abordagens curriculares que adotam uma prática reflexiva e contextualizada. Esses docentes rompem com o ciclo de repetições curriculares, construindo uma nova cultura de ensino marcada por uma concepção profissional da docência e por um papel catalisador do professor. O texto se estrutura sobre quatro eixos: entre os objetivos da escola e a cultura do ensino; a influência da formação e da experiência sobre o exercício da docência; O que ensinar? Da seleção dos conteúdos à contextualização da aprendizagem; o "jogo de concepções" entre professores de ensino médio. Conclui-se que o professor é um grande artífice da construção curricular que se materializa nas escolas. Daí a importância de se construir currículo com a escola e seus sujeitos e não para a escola.

Capital and land constraints encourage parties to establish mutually supportive and profitable cooperative relationships, then manifested in the form of an agreements, one of them by Build, Operate, and Transfer Agreement (BOT). The possibility of a problem in the BOT agreement is quite large, for example when a BOT agreement is in progress, the Land Owner has a debt and can’t afford to pay the debt, then the land owner can be declared bankrupt based on the Commercial Court’s verdict. One of the cases is the bankruptcy of PT. X (as a land owner) in 2014, 21 years before the verdict, which is 1993, PT. X had a BOT agreement with PT. Y (as a builder).

The main issues in this thesis are: 1. Are the buildings and the golf courses built by the builder above the debtor’s land which is bound with BOT agreement which the debtor is declared bankrupt before the transfer, including in bankrupt assets?; and 2. What are the legal protection for the builder as the BOT receiver due to the bankruptcy of land owner? This research is a normative legal research uses statute approach, conceptual approach, and case approach.

The results of this research is the buildings and all the facilities which are built by the builder are not including in bankrupt assets because Indonesian Land Law adheres to the principle of horizontal separation, so as long as no transfer has occurred the land owner only has the land, the buildings and all things which are built by builder belong to the builder. The legal protection for the builder as the BOT receiver due to the bankruptcy of the land owner are the curator can continue the BOT agreement based on Article 36 Law of Bankruptcy and Suspension of Obligation for Payment of Debts, make a novation, and the builder can file a compensation and then will become a concurrent creditor.
Formulasi Pertanggungjawaban Pidana Korporasi Dengan Adanya Peraturan Mahkamah Agung No. 13 Tahun 2016

The development of the concept of corporation not only had a positive impact but also followed by the development of crimes that could be done using corporations or also called corporate crime. Many laws and regulations that have accommodated corporation as legal subjects that can be asked for corporate criminal responsibility have not been followed by regulations governing procedures or procedures for examining corporations as perpetrators of criminal acts. This is very necessary because of the differences in characteristics between corporate crime and other conventional crimes. Responding to legal requirements that have been very urgent and there are distinct challenges for law enforcers because of the different treatment, then the Supreme Court issues Supreme Court Rules No. 13 of 2016. The problem regarding the procedure for corporate sentencing involved in criminal offenses is not only talking about material law but also about formal law or its procedural law. One of the aims and objectives of its formation is to fill the vacuum of criminal procedural law which until now has not regulated the procedures for handling corporations that carry out criminal cases. Supreme Court Rules No. 13 of 2016 is a legal rule aimed at assisting law enforcement officials in handling criminal cases with corporate actors and/or their administrators. This then became one form of thinking that could be the basis for assisting in the formation of criminal procedural laws governing corporations.
El guerrero y el técnico. Albano Harguindeguy y su relato sobre la represión y los desaparecidos (Argentina, 1976-2012)
Authors: Vera Canelo Paula
Published: April 2019

El artículo analiza la palabra pública de Albano Harguindeguy sobre la represión de la última dictadura civico-militar argentina y sobre los desaparecidos, entre 1976 y 2012. Para ello, recurre a los ejes conceptuales que Feld y Salvi (2016) proponen para abordar las declaraciones de los represores. En primer lugar, el trabajo identifica las características del relato público de Harguindeguy: qué dijo y qué no pudo dejar de decir sobre la represión y los desaparecidos. En segundo lugar, analiza el vínculo que construyó hacia ese relato, en términos de su propia responsabilidad y la de las Fuerzas Armadas: arrepentimiento, justificación, reivindicación, etc. Por último, explica cuáles fueron las principales condiciones de posibilidad de este relato: las posiciones desiguales que ocupó Harguindeguy entre 1976 y 2012, el tránsito de la dictadura a la democracia, y los vaivenes entre impunidad y justicia propios de la escena argentina de los últimos treinta y cinco años.
The comparative method for policy studies: the thorny aspects
Authors: Dogaru Cruceanu Tatiana-Camelia
Published: April 2019

Over the past decades, the comparative method has attracted the attention of the theorists, and studies based on this approach have increased in applied policy research. In their daily and strategically policy decisions, the decision makers from local, regional and national levels use more and more the comparative research methods, especially due to interlinked relationship and the need for bench learning and benchmarking practices. The comparative method allows the actors to analyse other experiences, and thus to take decisions more efficient. This is a normal, an inevitable situation, when the unit of analysis is a country, a field of matters or a process where researchers compare cases from empirical or theoretical point of view. The purpose of this paper is to provide a critical view on the capacity of comparative method to foster knowledge in policy studies. The intention is to see and to explore the utility of comparative method for policy studies and policy analysis, since a new approach “evidence-based policymaking” arise, emphasising the importance of using evidence from other political and policy systems.

The paper presents the use of phase change material (PCM) in window application that was studied in the framework of the ERA-NET-LAC Project “Solar Hybrid Translucent Component for Thermal Energy Storage in Buildings” (SOLTREN). Increase of energy savings in buildings is the main aim of this study. To achieve the aim, it has been decided to create a theoretical model of the impact of the PCM on the characteristics of the window and, at the next stage, to experimentally test the model. Paraffin has been chosen as the most suitable and available material as PCM. Pure paraffin has high transparency in liquid phase, and dull white colour in solid phase. The paper shows results of total transmittance and absorption spectra for different thicknesses of paraffin with a melting temperature of 35°C, as well as absorption of the glass sample with PCM at different angles of incidence of light.
Jewish Swimming and Sports Club Bar Kochba Bratislava – the Most Successful Sports Club of Slovakia in the Interwar Period
Authors: Bučka Peter
Published: April 2019

In this article, the author deals with the foundation, development, results and reasons of disappearance of the most successful sports club in the interwar era; the Jewish swimming and sports club Bar Kochba Bratislava. After the birth of Czechoslovakia, sports in Slovakia could develop on a national basis. Large national minorities had the same possibilities. To eliminate the risk of misusing sports for political purposes, sport representatives decided to organise it on the ethnic principle instead of the regional one. Thanks to this a wide variety of national sports organisations were established, including some Jewish ones. Even though Jews constituted only 2.01% of the population in the interwar period in today’s territory of Slovakia (Bergerová, 1992: 108), they succeeded not only in sports but in other areas of social life as well.

Terra firma-forme dermatosis (TFFD) or Duncan’s dirty dermatosis is a bizarre, acquired, and idiopathic dermatosis. It is characterized by its asymptomatic, yellowish, or brownish dirt-like lesions, resistant to usual washing with soap and water, but disappearing when rubbed with 70% ethyl alcohol or isopropyl alcohol. Swabbing with alcohol is both diagnostic and therapeutic means for this disorder. We present two boys, aged 14 and 11, with asymptomatic brownish, dirt-like lesions on the chest and forearms, respectively. Skin lesions were continuously present for more than a month. Both of the patients had usual hygiene habits. The diagnosis of TFFD was confirmed by rubbing with 70% ethyl alcohol which led to disappearance of the lesions. TFFD often causes much concern in patients and parents of affected children. Since its clinical picture is similar to some other dermatoses, the disease can be misdiagnosed. Therefore, it is important to recognize this dermatosis in dermatological and pediatric practice in order to explain the benign nature of the disease to patients and to avoid unnecessary diagnostic tests.
