Published: December 2021

Найбільш ефективним засобом зниження рівнів електричних, магнітних та електромагнітних полів широкого частотного діапазону у виробничих та побутових умовах є їх екранування. Але у реальних умовах потребують корекції і інші фізичні фактори. Показано, що найбільш критичними з них є акустичний шум та аероіонний склад повітря. Це обумовлює необхідність здійснювати нормалізацію фізичних факторів на комплексній основі. Застосування у якості матриці для електромагнітного екрана пінолатексу і наповнювача з залізорудного концентрату дозволяє знизити рівні електромагнітних полів і акустичного шуму до нормативних значень. Навіть, для частотних смуг 31,5 Гц та 63 Гц за товщини екрана 10 мм індекси зниження шуму складають 15-20 дБ. Для частот 6-8 кГц цей показник складає 40-45 дБ, що прийнято для більшості виробничих умов. При цьому коефіцієнти екранування магнітних полів промислової частоти та електромагнітних полів ультрависоких частот відповідають нормативним вимогам. Показано, що головним фактором деіонізації повітря є електростатичні заряди, які накопичуються на полімерних повітрях, яке до того ж є причиною спрямованого руху дрібнодисперсного пилу. Перевагою латексу є відсутність електризації поверхні, що дозволяє застосувати його для облицювання поверхонь великих площ. При цьому він має пружні модулі, близькі за значеннями до модулів матеріалів, які традиційно застосовуються для шумопоглинання. Найефективнішим методом нормалізації та підтримання на нормативному рівні концентрацій аероіонів обох полярностей є застосування пристроїв штучної іонізації повітря. Для рівномірного розподілу аероіонів у об’ємі приміщень застосовують розсіюючі екрани. Перевагою екранів з латексу є відсутність часткового поглинання іонів під час розсіювань. Запропонований підхід з нормалізації рівнів електромагнітних полів акустичного шуму та концентрацій аероіонів, разом із застосуванням систем клімат-контролю дозволяє підтримувати на нормативному рівні увесь комплекс фізичних факторів виробничого середовища. Це найбільш актуально для приміщень об’єктів критичної інфраструктури (головних щитів керування, диспетчерських тощо)

Metadata in the Digital Library
Authors: Gartner Richard
Published: December 2021

The range of metadata needed to run a digital library and preserve its collections in the long term is much more extensive and complicated than anything in its traditional counterpart. It includes the same 'descriptive' information which guides users to the resources they require but must supplement this with comprehensive 'administrative' metadata: this encompasses technical details of the files that make up its collections, the documentation of complex intellectual property rights and the extensive set needed to support its preservation in the long-term. To accommodate all of this requires the use of multiple metadata standards, all of which have to be brought together into a single integrated whole.

Metadata in the Digital Library is a complete guide to building a digital library metadata strategy from scratch, using established metadata standards bound together by the markup language XML. The book introduces the reader to the theory of metadata and shows how it can be applied in practice. It lays out the basic principles that should underlie any metadata strategy, including its relation to such fundamentals as the digital curation lifecycle, and demonstrates how they should be put into effect. It introduces the XML language and the key standards for each type of metadata, including Dublin Core and MODS for descriptive metadata and PREMIS for its administrative and preservation counterpart. Finally, the book shows how these can all be integrated using the packaging standard METS. Two case studies from the Warburg Institute in London show how the strategy can be implemented in a working environment.

The strategy laid out in this book will ensure that a digital library's metadata will support all of its operations, be fully interoperable with others and enable its long-term preservation. It assumes no prior knowledge of metadata, XML or any of the standards that it covers. It provides both an introduction to best practices in digital library metadata and a manual for their practical implementation.
The Characterization of Stratigraphic Play in Middle Baong Sand for Hydrocarbon Prospecting in Offshore North Sumatera Basin
Authors: Nurhasan A.
Published: December 2021

Pertamina EP is operating a small block in Offshore North Sumatera Basin where a couple of the fields are producing gas and condensate from the Belumai Carbonate. However, the wells production is depleting and several delineation wells are unable to find additional reserves, it is important to find a new play within the block. Few discoveries in the Middle Baong Sand (MBS) reservoir suggested a promising stratigraphic play to be explored, but it requires more detailed characterization of the reservoir extent. The Malacca strait-sourced MBS consists of several deposited sand packages during a mega sequence. The term MBS might represent a deltaic environment from a transgressive system tract of some marine shore bar or a basin floor fan. Each system has a distinct character (thickness, net to gross ratio, distribution) that must be evaluated before proposing an exploration well. The depositional environment and reservoir distribution are interpreted and modeled using regional 2D seismic and high-quality 3D seismic. Paleo-bathymetric interpretation from well samples shows a good correlation with the palinspastic reconstruction. The result shows that the Pertamia EP working area is located in the shore bar depositional environment. Seismic attributes are used to delineate reservoir distribution within the working block and well logs are used to constrain prospective sand bodies and water zones identification. Furthermore, source rock maturation and migration path and hydrocarbon occurrence from the discovery wells have been evaluated for hydrocarbon prospecting and risking. This study suggests a promising lead for hydrocarbon exploration in the study area and opens up a new opportunity for an underexplored play.
Analytical method to accurately estimate overpressure magnitude: The case study from Indonesia's Tertiary basins
Authors: Ramdhan A. M.
Published: December 2021

The most widely used overpressure estimation method is empirical method such as Eaton’s method. The nature of the empirical method is that it may work well in one area, but it may not work in other areas. In this paper, we try to develop more analytical approach to estimate overpressure, with the basis on understanding of overpressure generation. We then try to apply this method in Indonesia’s Tertiary basins, and it gives sensible results. The overpressure generating mechanism is analysed by direct inspection and comparison of sonic (and resistivity) vs density log responses to overpressure. From this step, we can understand whether overpressure is caused by disequilibrium compaction, unloading, or both. In the case that overpressure is generated by disequilibrium compaction mechanism, simple velocity-effective stress relation or equivalent depth method gives good match between estimated and measured pore pressure. If disequilibrium compaction and unloading contribute to overpressure, two steps are required to estimate overpressure magnitude. The first step is to analyse log response due to disequilibrium compaction and calculate disequilibrium compaction overpressure magnitude by methods as discussed above. The second step is to calculate the contribution of disequilibrium compaction and unloading to overpressure, based on effective stress history that has ever been experienced by sediments. By applying this two steps procedure, overpressure magnitude can be estimated accurately.
Redefining Reservoir Architecture of Hydrocarbon-Bearing Ngrayong Formation in Banyu Urip Area:New Insights to Unravel Hidden Potential in East Java Basin
Authors: Ahdyar L. O
Published: December 2021

Results of Banyu Urip (BU) carbonate exploration, appraisal and development drillings revealed the existence of hydrocarbon-contained in Serravallian deep-water clastic reservoir on top of the primary BU carbonate reservoir. This clastic reservoir is equivalent to the Ngrayong Formation in East Java Basin which is widely known as a mature exploration target and consists of a wide range of depositional environment from fluvio-deltaic (northern part of the Basin) to basin floor (southern part of the basin) with various reservoir quality. However, after a century of exploration activities in East Java Basin, commercial discoveries in the Ngrayong Formation are still considered insignificant (approximately 330 MMboe) (Mazied et al. 2016). This probably due to complex reservoir architecture posted high uncertainty of its reservoir presence, distribution, and quality as well challenging on their dynamic aspects such as un-known hydrocarbon connectivity, un-even contacts and low-deliverability. This paper will present new insights and the potential of Ngrayong clastic opportunity in BU area based on static and dynamic data including BU wells, newly reprocessed 3D seismic data, conventional core and thin sections, as well as integrated geologic and geophysical analyses. Integration of the available dataset suggest the presence of stacked deep water channels and deep water lobes systems. The distribution of stacked channels and lobes seem to be more predictive and widespread, hence providing a better understanding of its reservoir distribution. Furthermore, well data indicates approximately total of 100m net stacked clastic reservoirs consist of mixed carbonate-clastic materials, and have good reservoir pressure connectivity with the carbonate reservoir underneath. This mixed clastic-carbonate system in Ngrayong Formation is diagenetically-altered, and this diagenesis process plays as an important roles in modifying reservoir quality. Although carbonate cement and diagenetic overprint impose challenging reservoir quality prediction, a dissolution creates better reservoir quality, generates excess permeability and produces high flow reservoir. Detail study of reservoir architecture and diagenesis process are critical to better assess volumetric and development opportunity. These key components will open up new paradigm and essential for successful of Ngrayong Formation exploration in East Java Basin in order to contribute to the country’s energy demand.
New perspectives on the source rock facies of the Andaman Trough, offshore North Sumatra based on the latest onshore oil sampling and analysis
Authors: Ariyono D.
Published: December 2021

The Andaman sub-basin, located offshore Aceh Indonesia, is considered to be one of Indonesia’s most underexplored basins, despite its proximity to the giant gas and condensate fields of Arun, NSO A, NSO J and South Lhok Sukon, where in excess of 6 MMboe has been produced to date. The understanding of the Petroleum System in the offshore Andaman Trough, has historically been challenged by poor imaging of the basin architecture and limited penetration and retrieval of source rock intervals and hydrocarbon fluids for analysis. Mubadala Petroleum, as operator of the Andaman I PSC, conducted a geological field study to collect multiple oil samples from fourteen (14) onshore traditional wells across the Bireun and Aceh Timur Administrative District (Figure 1). Those samples were analyzed in laboratory for their physical properties and parameters derived from those analyzes where integrated to fully characterize oils produced in the onshore Aceh area and establish the organofacies and maturity of their source facies precursors. The results were then used as calibration for the analysis and subsurface modeling of the offshore petroleum system of the Andaman sub-basin. Previous authors have postulated that Late Oligocene to Early Miocene marine shales were the main source rocks for oil in the Andaman Trough. Oil samples collected onshore as part of this study however, were sourced by peak to late mature oil-prone lacustrine source rock facies, yielding high API (42.7 – 50.8°), low pour point, low sulphur, and low wax content fluids. Integration of these findings with the upgraded tectono-stratigraphic framework provided by the 2019 MC3D survey, reprocessed multi-vintage 2D, and reinterpretation of biostratigraphic analysis, has enabled the delineation of a postulated Paleogene lacustrine source rock facies in the Andaman Trough. This model does not preclude the potential of other source rock facies to be present and active within the Andaman Trough, including the gas-prone fluvial Eocene-Oligocene Parapat Formation, but it supports the possibility that oil may have been generated in the Andaman Trough.
Mechanism of Gravity-Driven Deformation Using Sandbox Modeling: A Case Study of The Tarakan Sub-Basin, East Kalimantan
Authors: Sapiie B.
Published: December 2021

Based on the observations of subsurface and bathymetric maps, various structural patterns are observed in the Tarakan Basin, especially in the Tarakan and Tidung Sub-basins. One of the hypotheses put forward in this study that the gravity-driven mechanism is responsible to generate the normal faults system and folds -thrust belt in the offshore Tarakan Basin. We conducted an integrated study using palinspatic reconstructions of several seismic sections and an analogue-sandbox modeling to observe and explain this gravity-driven. The deformation modeling, which is controlled by gravity requires special conditions that can trigger the movement. The three main parameters that cause gravity deformation to occur are lithology, loading, and slope. In the case of the Tarakan Basin, modeling was carried out by referring to the results of 2D-seismic palinspatic reconstructions. Besides, the additional information as a basis for modeling is also based on the current topographic and bathymetric data. The tectonic reconstruction is used as a reference for paleo-stress data. In theory, one of the factors determining the occurrence of this mechanism is the presence of detachment. This detachment manifests the over-pressure fluid anomaly in the rock, such as over-pressure shale and salt layers. To simulate the conditions that may closely be like the behavior in this detachment, bead materials were selected in the sandbox modeling. Twenty-two experiments were conducted to test the bead as the materials in this modeling, and more than thirty experiments were carried out to model this case. From more than ten realizations, the model with the closest results to seismic interpretation and palinspastic analyses were chosen. From the results of experiments that have been conducted, the development of thrust faults related to the development of normal faults. This evidence is in line with the deformation of gravity-driven mechanism.
Carbonate Pore System Characterization, a Study Case from Drowning Cap Sequence in VITA Field, ExxonMobil Block Cepu Limited (EMCL)
Authors: Dewi V.T
Published: December 2021

Carbonate rocks are known as one of the principal reservoir rocks in the world due to their good porosity and permeability. However, the heterogeneity of carbonate reservoir quality is difficult to predict. Variability of diagenetic processes overprinting carbonate depositional texture has resulted in a complex carbonate pore system. As a consequence, this complexity results in a harder reservoir characterization and also a discrepancy between actual and model properties, that leads to a harder history match in reservoir simulation. By presenting a study case from the Drowning Cap Sequence in the VITA Reservoir Block Cepu, this paper will present a comprehensive approach which focusing on characterization of a carbonate pore system for optimum geomodel, simulation and surveillance. This approach utilized static data of 100 ft total of cores, ±500 thin sections, well, and image logs. The study has resulted in definition of four Carbonate Reservoir Rock Types (RRT) which were clustered using the analysis of carbonate dominant pore types and the porosity-permeability relationship. Results revealed that there are 4 RRTs observed as follows: (1) RRT 1 – Touching Vugs-dominated, with high porosity and permeability, (2) RRT 2 – Interparticle- and Moldic-dominated, with moderate to high porosity value and lower permeability than RRT 1, (3) RRT 3 – Microfracture-dominated, with very low porosity value and low to moderate permeability, and (4) RRT 4 – Minimum Dissolution, with very low porosity and permeability value, lower than RRT 3. Each RRT was integrated with well and image logs to understand its characteristics and behavior. Ultimately, all data were integrated, analyzed and successfully captured carbonate reservoir quality variation, distribution and depositional evolution along with overprinted diagenetic processes vertically and laterally. This approach successfully captured carbonate heterogeneity which ultimately will be useful to develop better geological and reservoir simulation models after being integrated with dynamic data and observations.
Refined karst feature and fault identification through integrated wave field separation and imaging of Diffraction energy
Authors: Alay R.
Published: December 2021

In this abstract, a case study from offshore Indonesia is showcased with examples emphasizing integrated wave field separation methods with the objective of diffraction imaging towards refined karst feature and fault identification. For imaging optimally all diffraction energy, pre-migration and post-migration methods have been integrated. The dataset and examples in this abstract are in a complex geological setting in a very shallow water environment, with a subsurface that is characterized by large carbonate pinnacles containing large amount of karst features with thinning and thickening carbonate layers. For the purpose of refined imaging of diffraction energy only, the total wave field has been separated into specular reflections and diffractions prior to migration and these have been integrated with existing post-migration wave field separation methods. Both the pre-migration and post-migration wave field separation methods have their advantages and disadvantages and is discussed later in this abstract. Diffraction energy, in general is much lower in amplitude than the specular reflections and separately imaging these, unveils higher resolution small scale geological features such as karst features and faults complementing the total wave field PSDM data. With existing industry available methods applying wave field separation in either pre-migration or post-migration stage, limitations have been observed, and therefore we propose in this abstract to integrate both methods and take advantage of the improvements showcased with examples throughout the abstract.
Optimizing Borehole Images to Predict Porosity in New Discovery Limestone Minahaki Formation Pia-001 Exploration Well Matindok Block Central Sulawesi
Authors: Guspudin B.
Published: December 2021

PIA-001 exploration well is located 4 km away from Donggi Gas Field, Central Sulawesi. The objective of the well is to unlock the hydrocarbon potential in Minahaki Formation. However, this is not an easy task to do. Minahaki Formation is mainly comprised of heterogeneous limestone facies, in which the primary and secondary porosity varies from facies to facies at different scales. Moreover, the diagenesis processes, such as dissolution and cementation alter each facies differently. These are the factors that introduce high uncertainty in the porosity distribution and estimation in Minahaki Formation. The conventional method to predict porosity utilizes conventional logs such as density, neutron and sonic log. However, this method is not suitable to be used in heterogeneous limestone. Its low vertical sampling rates relative to the porosity distribution, fails to predict accurately the porosity and productivity potential of these complex reservoirs. Hence, porosity needs to be generated using other type of data. The ideal data to tackle this complexity is by using electrical borehole image log which was logged within water based mud. This data is in high resolution and cover 360-degree view of borehole wall. On top of that, by using the newly developed carbonate textural and porosity estimation method, the porosity as well as the productivity potential can be accurately generated. This carbonate textural and porosity computation method has been performed in PIA-001 Well. It is observed that the secondary porosity in PIA-001 well comprises of vugs connected to fractures, vugs connected to bed boundary and connected vugs with some isolated vugs, with the total porosity ranges from 10-20%. Generally, this porosity trend shows good correlation with the porosity result from routine core analysis. Besides that, the porosity as well as the connectivity from this method is used to assist the DST interval selection. Based on this study, it can be concluded that electrical borehole image contributes to significant improvement in heterogeneous limestone porosity estimation. The porosity result also shows a good correlation with the porosity from routine core analysis and flow potential from DST Test. It is suggested to perform the same analysis to improve the success ratio in exploration well with the same reservoir challenges.

Published: December 2021

This article highlights some of the tensions that exist for Hmong people who identify as lesbian, gay, bisexual, transgender, and queer (LGBTQ). It uncovers differences and similarities found between the experiences of queer Hmong youth and the larger population of queer youth living in the United States. Despite the perception that a traditional Hmong culture holds no place for queer Hmong Americans, individuals are finding spaces for acceptance and slowly moving the larger Hmong community to a place of understanding and tolerance. A vital part of this movement was Shades of Yellow (SOY), an organization that supported queer Hmong from its inception in 2005 until the group disbanded in June 2017. The life stories of three of its members inform this study, offering a more nuanced look at the experiences of queer Hmong youth living in the Midwest.

Farmers’ Subsistence in Indonesian Rice Farming
Authors: Utami Anisa , Harianto Harianto
Published: December 2021

Along with the importance of the rice industry in the agricultural sector and rural development in Indonesia, it arguably requires the understanding of whether rice farmers have been experiencing changes in their agricultural practices. Within the existing literature, it is commonly found that most farmers in developing countries are characterized as subsistence farmers. This paper aims to explore what factors affecting the degree of farmers’ subsistence in the Indonesian rice industry. To this end, this study employed regression analysis using data from the national agricultural survey in 2014. The empirical results find that both the characteristics of farm households and rice on-farm characteristics have statistically significant effects on the farmers’ decision whether to commercialize or become subsistence. In addition, the farm gate price is also found to have a statistically significant effect, but the effect is found to be relatively small. In general, this study suggests that subsistence farming in the Indonesian rice industry is still significant though many literatures have emphasized the existence of structural change in the agricultural system in Indonesia.

“Como quem partilha uma alegria”
Authors: Fernandes Márcio Luiz , Koller Felipe Sérgio , Luz Neto João Pedro da
Published: December 2021

Na exortação apostólica Evangelii Gaudium, o Papa Francisco traça uma relação de clara interdependência entre a missão evangelizadora da comunidade eclesial e a experiência de alegria que ela realiza na fé em Jesus Cristo. Este trabalho apresenta contribuições da teologia de Alexander Schmemann, em For the Life of the World, e da filosofia de Fabrice Hadjadj, em O paraíso à porta, que podem enriquecer a recepção desse documento programático do pontificado de Francisco. Nesse percurso, individuamos quatro pontos de convergência entre a visão dos dois autores: a redescoberta da dimensão eucarística da alegria, enquanto experiência de um dom que se prolonga como ação de graças; a dimensão pascal, que atravessa o mal e a dor fecundando-os sem negá-los; a dimensão epifânica, como olhar que permite reconhecer no cotidiano a proximidade do mistério; e a dimensão transformadora, enquanto gratuidade que se transborda em um serviço verdadeiramente desinteressado.
O anúncio de Jesus e alguns elementos para a teologia da missão no contexto latino-americano
Authors: Mikuszka Gelson Luiz
Published: December 2021

Refletimos o anúncio de Jesus, pensando em alguns elementos para uma teologia da missão mais compreensível para o contexto latino-americano, acessível e aliada aos dinamismos dos contextos eclesiais de hoje, de modo a anunciar a fé cristã nos tempos atuais. Dois elementos básicos norteiam nossa reflexão. Primeiro, as reflexões de José Comblin, que pondera sobre uma teologia da missão gerida pela teologia do Espírito e focada na realidade latino-americana. Segundo, o anúncio da mensagem de Jesus contemporanizado na realidade presente, cujo perfil social se apresenta líquido, de fortes tensões sociopolíticas, econômicas e sanitárias e que requer uma ação junto às pessoas inseridas nesta realidade, carentes de respostas concretas para sua vida.
Sentidos de esperanza en pandemia. Entrevistas cualitativas en investigación social
Authors: Méndez Fierros Hugo , Soto Curiel Jesús Adolfo
Published: December 2021

La pandemia significó en muchos sentidos y en situaciones particulares, una ruptura de los esquemas de comunicación en la vida cotidiana. La imposición de encierro y confinamiento, el cierre de las fronteras entre países, el cubrebocas que impide la salida del sonido oral. Los procesos de intercambio comunicacional cara a cara con quienes viven fuera del hogar se imposibilitaron. Por ello, las motivaciones centrales de este proyecto de investigación fueron recuperar, en términos prácticos, los espacios de comunicación cara a cara a través de entrevistas semiestructuradas. Escuchar, documentar, organizar, sistematizar y pensar los sentidos de esperanza en pandemia a través de la recuperación discursiva de las emociones sociales en un contexto de fronteras geográficas y simbólicas. En este libro los lectores podrán encontrar las representaciones de cooperación humana y esperanza en tiempos de pandemia, que once agentes de diversos ámbitos de la realidad social fronteriza bajacaliforniana, construyeron entre marzo y octubre del 2020.
Activity of isolated specific bacteriophage in treatment of chronic osteomyelitis induced by multiple drug resistance Pseudomonas aeruginosa in Rabbits
Authors: Sarhan Sarhan Rashid
Published: December 2021

This study was conducted to find out the possibility of using the Pseudomonas aeruginosa specific-bacteriophage as an alternative to antibiotics in treatment of chronic osteomyelitis in rabbits by injection of Pseudomonas aeruginosa suspension in tibia. The current study included an isolation of bacteriophage from sewage water by using agar overlay method and also an isolation of the bacteria from patients suffering from post-traumatic bone infection. The second experiment was in-vivo evaluation of phage activity in treatment of chronic osteomyelitis in rabbits. All animals of infected groups with Pseudomonas aeruginosa before treatment exhibited histopathological changes after 35 days of infection, the infected groups showed chronic osteomyelitis represented by sever chronic inflammatory cells infiltrates mainly lymphocytes, and macrophages and hemorrhage between bone trabeculae, also some sections showed extensive fibrosis in the marrow spaces. The treated group with P. aeruginosa specific – bacteriophage (1.5 ×107) PFU/ml for 10 days showed early repair elucidated by presence whorls of chondrocytes, and also the presence of multiple osteoblasts indicated bone formations. Also the presence of extensive fibrosis in the marrow space with present of osteoblasts indicated bone formations and repair.
Nanone interactions in antibody of living systems

One of the facts about how nanoparticle assemble and act is revealed using carbon value in biomolecule of living system here. This is how the biomolecules interact to bring about a micro or even macro level interaction in system of interest. This study shows micro level understanding can be better utilized from carbon analysis at nano level. I plan to extend this phenomena of change from nano to micro for building large scale applications in human nature. Applications include corrections in both at sequence and structure level for permanent recovery of defective one, adding flavor to the existing biomolecule for faster delivery or recovery etc. I have demonstrated here the active role played by carbon and all. This might be extended to another system of setup where new applications yet to be created. One can extend this phenomena of change from nano to large scale one.
Pitääkö vaieta, saako syyllistää?
Authors: Lyytimäki Jari , Pihkala Panu
Published: December 2021

Mikä on paras tapa viestiä kestävyyskysymyksistä? Tässä katsauksessa tarkastellaan kestävyysmurrokseen liittyvää viestintää erityisesti ilmastoviestinnän näkökulmasta. Ilmastoviestintää on arvosteltu ihmisiä liikaa tai tarpeettomasti pelottelevaksi ja syyllistäväksi. Katsauksessa perustellaan viimeaikaisesta kotimaisesta ilmastokeskustelusta otettujen esimerkkien avulla, miksi tällainen arvostelu on pääosin perusteetonta. Katsauksen päätelmänä on, että syyllisyys on hyödyllinen tunne, jota ei ole syytä karttaa, vaan jota tulee rakentavasti hyödyntää ilmasto- ja kestävyysviestinnässä.
Elinkeinotoiminnan käytännöt ja reilun siirtymän mahdollisuudet Portugalin supistuvalla maaseudulla
Authors: Kovanen Sunna
Published: December 2021

Tämä tutkimus tarkastelee reilun siirtymän mahdollisuuksia supistuvan maaseudun kontekstissa, jossa siirtymäpolitiikan haasteiksi tunnistetaan supistumisen kokemukset ja niiden kapitalosentriset tulkinnat. Siirtymän mahdollisuuksia tutkitaan ekologiseen ja sosiaaliseen kestävyyteen pyrkivän elinkeinotoiminnan käytäntöjen sekä aluekehityksen vakiintuneiden instituutioiden näkökulmasta. Tutkimus kysyy, miten ekososiaalinen elinkeinotoiminta voi edistää reilua siirtymää supistuvan maaseudun oloissa ja millaisia jännitteitä ekososiaalisen elinkeinotoiminnan ja aluekehityksen instituutioiden välillä ilmenee, kun kapitalosentrismiä haastavat poliittiset käytännöt valtavirtaistuvat. Empiirisesti tutkimus koskee kolmen elinkeinotoimijan työtä Alentejon alueella Portugalissa. Tutkimusaineisto on kerätty laadullisten teemahaastattelujen, fokusoidun etnografian ja dokumenttianalyysin avulla vuoden 2019 aikana. Ekososiaalinen elinkeinotoiminta voi edistää reilua siirtymää kiinnittämällä nuoria, koulutettuja aktiiveja sekä globaalin kansalaistoiminnan verkostoja maaseudun paikallistalouteen ja -yhteisöihin. Samanaikaisesti elinkeinotoimijoiden haasteena on vastata puuttuvien peruspalveluiden ja toimeentulon tarpeeseen. Siinä onnistuessaan ne voivat tarjota pitkäjänteisen, tilanteisen oppimisen paikkoja taloudellisen vastuun ja kestävän hyvinvoinnin toteuttamisesta maaseudun arjessa. Tämä mahdollisuus jää toistaiseksi institutionalisoituneen kapitalosentrisen aluekehityksen kehyksessä huomaamatta, missä kehityksen ongelma määrittyy suhteellisen taantumisen kautta. Talouden supistuminen kriisin johdosta voi edesauttaa ekososiaalisten elinkeinojen skaalautumista, mutta nopea kasvu voi riskeerata niiden vakauden ja kestävyyden.
Mitä on tekeillä pienessä puutarhassa?
Authors: Kaartinen Miina
Published: December 2021

Artikkelissa pohditaan sosiaalityön tehtävää ekologisten kriisien aikakaudella lahtelaisen yhteisöpuutarhaprojektin kautta. Yhdistämällä kulttuurintutkimusta ekososiaalisen ja yhteisöllisen sosiaalityön teoreettisiin keskusteluihin, kysytään miten paikallinen yhteisöpuutarha voi auttaa kuvittelemaan tulevaisuuden sosiaalityötä. Aineiston muodostavat kirjoittajan kokemukset kansalaislähtöisen yhteisöpuutarhan perustamisesta ja projektin parissa työskentelemisestä keväästä 2019 kevääseen 2020. Autoetnografinen analyysi osoittaa, kuinka sosiaalityölle olennaisia valtakamppailuja käydään moninaisissa arkisissa käytännöissä ja näin ollen potentiaalisia vaikuttamisen paikkoja on tarjolla runsaasti myös vakiintuneiden työ- ja ajattelutapojen ulkopuolella. Puutarhaprojekti liitetään artikkelissa osaksi pohjoismaista yhdyskuntatyön perinnettä, ja tarkemmin sieltä löytyvää ruohonjuuritason sosiaalityötä. Artikkeli ehdottaa ruohonjuuritason sosiaalityötä työotteeksi ja käsitteeksi, jonka avulla lähteä osaltaan toteuttamaan siirtymää kohti ekohyvinvointivaltiota.

Studi in onore di Willy Cingano per il suo 70° compleanno
Authors: Prodi Enrico Emanuele , Vecchiato Stefano
Published: December 2021

The volume collects thirty-six essays honouring Ettore (‘Willy’) Cingano, Professor of Greek Language and Literature at Ca’ Foscari University of Venice. Current and former colleagues, students, and friends have contributed new studies on various aspects of Classical antiquity to celebrate his seventieth birthday. The work consists of seven main sections, mirroring and complementing Willy’s research interests. We start with the subjects to which Willy has contributed the most during his career, early Greek hexameter poetry (chapters 2-6: Calame, Coward, Currie, Meliadò, Sider) and lyric, broadly intended (chapters 7-15: Spelman, Cannatà Fera, Le Meur, Prodi, Tosi, Vecchiato, Hadjimichael, D’Alessio and Prauscello, de Kreij). Next come tragedy (Lomiento, Dorati), Hellenistic and later Greek poetry (Perale, Hunter, Bowie, Franceschini), historiographical and other Greek prose (Andolfi, De Vido, Gostoli, Cohen-Skalli, Kaczko), Latin poetry (Barchiesi, Garani, Mastandrea, Mondin), and finally linguistics and the history of scholarship, ancient and modern (Benuzzi, Cassio, Giangiulio, Guidorizzi, Tribulato). The volume is bookended by a collection of translations from medieval and modern Greek poetry (Carpinato) and a reflection on the dynamic aspect of the sublime (Schiesaro).

Fato e maledizione nell’Antigonedi Sofocle
Authors: Dorati Marco
Published: December 2021

The paper analyses the presence and function of curses in Sophocles’Antigone. In particular, it explores the interaction that the introduction of predetermined elements into the plot of the tragedy creates with the pre-existing fate. Scarcely relevant on the level of the actual development of events, the curse nevertheless plays a significant role on the semantic level.
