Wintering Areas, Migratory Connectivity and Habitat Fidelity of Three Declining Nearctic- Neotropical Migrant Swallows
Authors: Imlay Tara Leah , Hobson Keith A. , Roberto-Charron Amélie , Leonard Marty L.
Published: October 2018

Conservation efforts directed at population declines for migratory animals must consider threats occurring at different stages often separated by vast distances. Furthermore, connectivity between populations and fidelity of individuals to specific habitats during the annual cycle are also important considerations. Avian aerial insectivores are experiencing steep population declines in North America, and those declines may be driven, in part, by conditions on the wintering grounds. Here, using geolocators (2 species; 4 individuals) and stable isotope (δ2H, δ13C and δ15N) measurements of feathers (3 species; 841 individuals), we identified approximate winter areas, and assessed migratory connectivity and among-year winter habitat fidelity for three aerial insectivores (Bank Swallow Riparia riparia, Barn Swallow Hirundo rustica and Cliff Swallow Petrochelidon pyrrhonota) that breed in northeastern North America. All three species of swallows are declining in this region. Our results, largely from the stable isotope analysis, suggest that these species likely winter throughout the Cerrado, La Plata Basin, and the Pampas, in South America. These most likely areas were similar among years (2013-2016) for Bank and Cliff Swallows, but varied for Barn Swallows (2014-2016). We found weak migratory connectivity for all three species, and, with one exception, weak habitat fidelity among years for individuals. For individual Barn Swallows captured in two or more years, we found high repeatability in δ13C values, suggesting some fidelity to similar habitats among years. The most likely wintering areas for these species coincide with large areas of South America experiencing high rates of land-use change.
Immigration, Incest and Post-Nationality in Krys Lee’s “The Believer”
Authors: Owen Jean
Published: October 2018

This article explores the idea of a drifting house, a house with no fixed coordinates, a concept that is central to an understanding of immigration. It can also describe what Anaïs Nin referred to as a house of incest, which means that under such a roof, all traditional familial boundaries are mobilised, either being crossed or absent to begin with. This is the situation for Jenny and her father in Krys Lee’s short story, “The Believer,” from her debut book Drifting House (2012). After her mother murders a delivery boy and is incarcerated in a high-security psychiatric facility, Jenny and her father become dislocated from their life as immigrants to the United States. Eventually, daughter and father take a road trip to visit Jenny’s mother and then drive on to Las Vegas, where their life as immigrants began and where they will now cross the ultimate boundary. Very few women writers have addressed the emotive theme of incest from the position of a daughter’s willingness to participate or even initiate the sexual encounter. Krys Lee twins immigration with incest to draw significant parallels between the two situations. In doing so, she demonstrates how the European and Korean past remains relevant to post-national literature.
Aliens in an Alien World: The Portrayal of the Aliens and Humans in the Man Who Fell to Earth by Nicholas Roeg and Under the Skin by Jonathan Glazer
Authors: Suppia Alfredo , Mazierska Ewa
Published: October 2018

The article examines The Man Who Fell to Earth by Nicholas Roeg and Under the Skin by Jonathan Glazer, comparing them with each other and their respective literary originals (hypotexts), in order to establish how aliens and humans are represented in these films and how these representations reflect their respective ideologies. The authors argue that while Roeg’s film, in common with its original, uses the story of Newton to criticise corporate capitalism, Glazer’s film plays down the political aspect of the film, concerning industrial farming and exploitation of the underclass by the political elites, pertaining to neoliberalism, to focus on the problems of identity.

Approximation of Information Divergences for Statistical Learning with Applications
Authors: Stehlík Milan , Somorčík Ján , Střelec Luboš , Antoch Jaromír
Published: October 2018

In this paper we give a partial response to one of the most important statistical questions, namely, what optimal statistical decisions are and how they are related to (statistical) information theory. We exemplify the necessity of understanding the structure of information divergences and their approximations, which may in particular be understood through deconvolution. Deconvolution of information divergences is illustrated in the exponential family of distributions, leading to the optimal tests in the Bahadur sense. We provide a new approximation of I-divergences using the Fourier transformation, saddle point approximation, and uniform convergence of the Euler polygons. Uniform approximation of deconvoluted parts of I-divergences is also discussed. Our approach is illustrated on a real data example.
Inheritance Patterns of Coat Colouration and Horn Number in Jacob Sheep
Authors: McEwan N.R. , Anjola O.A.
Published: October 2018

The allele for black coat colour is dominant relative to the allele for lilac in Jacob sheep and is affected by a single gene locus. The percentage of this colouration, as opposed to white fleece, across the body has a heritability value of 0.255. The mode of inheritance for horn number in these animals is less clear, with neither the trait for 2 horns, nor for 4 horns being totally dominant, based on crosses of 2 x 2-horned parents and 4 x 4-horned parents; although in these examples the majority of lambs had the same number of horns as their parents. However, when one parent had 2 horns and the other had 4 horns, the gender of the 4-horned parent appeared to influence the frequency of 4-horned offspring; 77% of lambs born to a 4-horned dam being 4-horned, but only 50% when the 4-horned parent was the sire. These data suggest evidence for sex-limiting factors being involved in determining the number of horns in this breed.
The Garrison of the Roman Fort at Porolissum (Dacia). The Analysis of the Tile-Stamps
Authors: Oprean Coriolan Horatiu
Published: October 2018

The author is dealing with the tile-stamps found in the Roman auxiliary fort at Porolissum attempting to establish which of the many units recorded on tile-stamps stayed in garrison at Porolissum. The author of the present article is arguing his own hypothesis on the subject, based on his own excavations at Porolissum and on all the data gathered from the scientific literature. He finally proposes two tables and a graph that correlate all the information on the troops known from the tile-stamps and stone inscriptions, establishing which of them were in garrison at Porolissum and which were only temporarily attached for building activity. At the same time he sets in chronological order the tile-stamps, demonstrating that the three units which built the headquarters building and the gates of the fort (coh III, L VII GF, L III G) were brought to the Porolissum area late in Hadrian‘s reign, to build in stone the fort and other military facilities in the limes area of Porolissum. The permanent garrison of the fort was composed during the 2nd century AD of two infantry auxiliary units, cohors I Brittonum and cohors V Lingonum, while a third one, numerus Palmyrenorum was probably lodged in a smaller fort situated 500 m away, on the Citera Hill. In the third century, cohors V Lingonum was still there, cohors I Brittonum also for Caracalla‘s time (even not recorded by any later inscription, but, at the same time, not attested in another fort), while the smaller Citera Hill fort was out of use and the numerus Palmyrenorum Porolissensium was moved inside the big fort from Pomet Hill. The author is concluding that the garrison of the military site Porolissum was not changed during the Roman rule in Dacia, all the other tile-stamps found belonging to units brought mainly during the 2nd century to built the military facilities of this strengthened sector of the frontier.
Reading Problems: Literacy and the Dynamics of Thought
Authors: Bell Jeffrey A.
Published: October 2018

In this article, we address the problem of predication, or the problem of connecting conceptual predicates to the sets of properties and attributes that correspond to these predicates. We take as our starting point Mark Wilson’s work, especially “Predicate meets Property,” and add to it a metaphysics of problems that one finds in the work of Gilles Deleuze. This enables us to understand the relationship between a predicate and the set of properties in terms of the relationship between a solution to a problem. The advantage of this approach is that it helps to illuminate the key issues involved in contemporary work on human reasoning. We sketch some of these advantages by looking to recent work on literacy and how literacy affects the capacity to engage in formal reasoning.
Heidegger, the Given, and the Second Nature of Entities
Authors: Bounds Graham
Published: October 2018

In this paper I draw from Martin Heidegger’s phenomenology of the 1920s to outline some basic features of his theory of intentionality that I believe have not been fully appreciated or utilized, and that allow for both novel and fruitful interventions in questions about meaning, the relationship between mind and the world, and epistemic justification, principally as they appear in John McDowell’s synoptic project in Mind and World. I argue that while elements of McDowell’s picture are ultimately unsatisfying and problematic, much of his conceptual framework can and should be put into dialogue with Heidegger’s, and that in so doing we make available powerful resources for amending the McDowellian account. Moreover, these emendations have attractive implications for his distinctive desiderata. In particular, they provide original conceptions of normativity’s place in nature, of the boundaries of the space of reasons, and of the relationship between the answerability of thought both to the world and to human beings as a rational community.
The Illusion of Agency as a Mark of Ultimacy
Authors: Nicholson Hugh
Published: October 2018

This essay proposes that action unaccompanied by the usual feeling of conscious agency constitutes a “mark of ultimacy.” Characteristically religious statements of “agentless action” find support in social psychological and cognitive scientific research that calls into question the intuitive belief that conscious thought causes action. An awareness of the limits of our powers of will lies at the the core of those limit experiences that provide the context for the meaningfulness of religious language.
Hermeneutics of Resistance in Marion’s Phenomenology of Givenness
Authors: Șandru Adrian-Răzvan
Published: October 2018

My goal in this paper is to investigate the role of the subject in Jean-Luc Marion’s phenomenology aided by his interpretation of the Kantian categories in ‟Being Given” and ‟In Excess”. I shall relate Marion’s hypothetical saturation of the Kantian categories to the suspension of the I-identity. The inner mechanism of this suspension will be shown to consist in a critical resistance to an excessive intuition that is defined by a failed attempt at the conceptualizing of intuitions. This failure shall manifest the saturated phenomenon as a counter-experience. The critical resistance to an excessive intuition acts as a temporary activity of the subject leading to its role as interpreter inscribed in an infinite hermeneutic. Based on this I argue that Marion’s subject is not destroyed by an excessive intuition but is only called upon to investigate a phenomenon from a multitude of perspectives. I hold this to be of the essence for Marion, as it explains the possibility of interpreting and experiencing the given as a given during the encounter with the given in which both the subject as well as the given become manifest. I shall argue thus that the recourse to Kant further clarifies Marion’s account of a critical, resistant subject. However, this does not mean that I am arguing for Kant’s categories, but that I hold them to have an important explanatory role for Marion’s phenomenology.

Diurnal variation of steroid hormones and their reference intervals using mass spectrometric analysis
Authors: Parikh T P , Stolze B , Ozarda Y , Jonklaas J , Welsh K , Masika L , Hill M , DeCherney A , Soldin S J
Published: October 2018

Objective

Accurate measurement of steroid hormones remains challenging. Mass spectrometry affords a reliable means for quantitating steroid profiles accurately. Our objective was to establish and define (1) the extent of diurnal fluctuations in steroid concentrations that potentially necessitate strict adherence to time of sample acquisition and (2) time-dependent steroid reference intervals.

Design

Nine steroid markers were examined in couplets in males and females.

Methods

Using isotope dilution high-performance liquid chromatography–tandem mass spectrometric (LC–MS/MS) analysis, we developed a multi-steroid profile requiring only a minimal volume of serum (0.1 mL). Couplet (AM and PM) measurements of steroid hormones for 120 healthy females (F) and 62 healthy males (M) were obtained. Patients were recruited from several participating centers.

Results

The following diurnal values were noted to be significantly different in both females and males: cortisone, cortisol, corticosterone, 11 deoxycortisol (11 DOC), androstenedione, 17a-hydroxyprogesterone (17 OHP) and dehydroepiandrosterone (DHEA). Testosterone was only found to have significant diurnal variance in males. Progesterone showed no significant difference in AM and PM values for either groups and thus may provide an internal control.

Conclusions

When diagnosing endocrine disorders, it is imperative to acknowledge the 24-h diurnal variation of the biochemical steroid markers. We highlight the importance of standardization of collection times and appropriate implementation of reference intervals.

Precis

We identify diurnal fluctuations in steroid concentrations with time of day and emphasize the importance of adhering to firm time of sample acquisition.

Authors: Omidpanah Neda , Jalilian Negin , Vaisi-Raygani Asad , Sadeghi Masoud , Mozaffari Hamid Reza
Published: October 2018

Background: Myocardial infarction (MI) is one of the most common cardiovascular diseases. It accounts for about half of death cases in Iran. The objective of this study was to compare the activity of butyrylcholinesterase (BChE) and acetylcholinesterase (AChE) enzymes in serum and saliva of the MI patients compared to the healthy controls.
Methods: Serum and salivary BChE and AChE levels were measured immediately following MI, and then 24 and 72 hours later. Four mL of blood and two mL saliva were collected for this purpose. These measurements were also collected in 30 healthy controls. The enzymes were assayed using spectrophotometry.
Results: The activity of salivary AChE in the MI patients was lower than that of the healthy controls right after, 24 hours, and 72 hours following MI. However, serum AChE did not show a significant difference between the two groups. The activity of serum BChE in the MI patients was lower than that of the healthy controls right after, 24 hours, and 72 hours following MI. However, salivary BChE did not show a significant difference between the two groups.
Conclusion: The activity of salivary AChE decreased in the MI patients compared to the healthy controls, which can be a marker to diagnose MI in the future.

Seleksi Parameter Pembentuk Indeks Kualitas Perairan untuk Pengembangan Budidaya Laut: Studi Kasus Perairan Teluk Sinabang, Aceh
Authors: - Erlania , Radiarta I Nyoman , Haryadi Joni
Published: October 2018

Indeks Kualitas Perairan (Water Quality Indices/WQI) telah dikembangkan dan digunakan untuk menganalisis dan menginterpreasikan kondisi perairan, namun implementasi secara spesifik pada budidaya laut masih belum banyak dilakukan. Penelitian ini bertujuan untuk menganalisis parameter penting pembentuk WQI dalam penentuan kesesuaian perairan untuk pengembangan budidaya laut di perairan Teluk Sinabang, Aceh. Nilai pengukuran parameter kualitas perairan yang terkumpul sebanyak 63 titik pengamatan untuk data in situ, dalam proses analisis statistik direduksi menjadi 20 titik pengamatan berdasarkan jumlah data ek situ. Parameter yang diukur meliputi suhu, pH, DO, TDS, konduktivitas, BOD, N total, nitrat, nitrit, amonium, P total, dan ortofosfat. Penghitungan nilai WQI dilakukan dengan tiga pendekatan, yaitu: (1) berdasarkan seluruh parameter (WQIobj); (2) parameter hasil seleksi menggunakan principal component analysis/PCA (WQImin-x); dan (3) parameter kunci yang dipilih menurut kebutuhan aktivitas budidaya laut secara umum (WQImin-aq). Hasil penelitian menunjukkan bahwa nilai WQImin yangpaling mendekati nilai WQIobj (72,67) adalah WQImin-2 (69,75) dan diikuti oleh WQImin-aq (60,19).Hal inimenunjukkan bahwa parameter yang membangun WQImin-2 dan WQImin-aq sudah cukup mewakili untuk menggambarkan kondisi perairan Teluk Sinabang. Kedua nilai WQImin yang diperoleh berdasarkan beberapa parameterterseleksi mengindikasikan bahwa nilai tersebut secara umum dapat digunakan untuk mengetahui kelayakan suatu perairan untuk pengembangan budidaya laut. Kondisi perairan Teluk Sinabang tergolong baik (level II) berdasarkan nilai WQIobj dan sedang (level III) berdasarkan kedua WQImin, yang mengindikasikan bahwa aktivitas budidaya masih dapat dilakukan pada perairan tersebut dengan memperhatikan aspek kelestarian lingkungan perairan.

Rumput laut merupakan salah satu primadona produksi perikanan budi daya di Indonesia. Ektensifikasi lokasi budi daya rumput laut telah menyebar sampai ke pulau-pulau terdepan Indonesia. Perluasan kawasan ini harus didukung oleh ketersediaan data dan informasi yang akurat tentang kesesuaian perairan lokasi budi daya. Penelitian ini bertujuan untuk melakukan analisis spasial kesesuaian dan daya dukung perairan untuk pengembangan budi daya rumput laut di Kabupaten Simeulue, Aceh. Penelitian dilaksanakan pada Agustus 2015, dan berlokasi di tiga teluk besar yaitu Teluk Sibigo, Teluk Dalam, dan Teluk Sinabang. Analisis spasial kesesuaian lahan dilakukan dengan sistem informasi geografis berdasarkan multi criteria evaluation dengan menggabungkan tiga submodel yaitu fisik dan geografi, kualitas air, dan sosial infrastruktur. Daya dukung kawasan dihitung dengan pendekatan kapasitas unit budi daya di perairan tersebut. Hasil analisis menunjukkan bahwa ketiga teluk memiliki potensi pengembangan dengan luasan yang bervariasi: 159 ha (Teluk Sibigo), 808 ha (Teluk Dalam), dan 684 ha (Teluk Sinabang). Perhitungan daya dukung menunjukkan bahwa Teluk Dalam mempunyai kapasitas yang terluas yaitu 494,7 ha. Pemanfaatan kawasan secara maksimal dapat mencapai produksi berkisar antara 723-3030 ton/siklus tanam. Kesesuaian lahan (zonasi) dan daya dukung perairan yang dihasilkan dalam penelitian ini dapat dijadikan landasan penting mendukung penerapan budi daya perikanan yang berbasis ekosistem.

Tarım sektörünün stratejik bir öneme sahip olduğu yaygın olarak kabul edilmektedir. Artan nüfusun gıda ihtiyacının karşılanması, gıda güvenliğinin sağlanması ve doğal kaynakların korunması gibi hususlar tarım sektörünün önemini artırmaktadır. Tarım sektörünün bu özelliği tarımsal arz güvenliğinin garanti altına alınmasını zorunlu kılmaktadır. Bu zorunluluk tarım sektörünün devlet tarafından öncelikli sektör olarak kabul edilip, uygun politikalarla desteklenmesini gerektirmektedir. Çalışmanın amacı tarımın stratejik önemine ve arz güvenliğinin sağlanması gerekliliğine dikkat çekmektir. Bu amaç çerçevesinde tarım sektörüne yönelik devlet müdahalesinin genel özellikleri ortaya koyularak, küresel düzeyde tarım politikalarındaki değişimin Türkiye tarım politikalarına yansımaları değerlendirilmiştir. Küresel ölçekte de gözlendiği gibi, Türkiye’de tarımsal üretim önemli ölçüde piyasalaştırılmıştır. Piyasalaşmaya bağlı olarak gıda ve arz güvenliğine ilişkin önemli sorunların var olduğu gözlenmektedir. Bu nedenle tarımsal arz güvenliğini sağlanma yönelik politika değişikliklerinin stratejik biçimde ele alınarak uygulamaya sokulması kaçınılmazdır.

The objective of the study was to investigate the behavior of leaf transpiration (E) and stomatal conductance (Gs) of sugarcane in function of photosynthetically active radiation (PAR) and vapour-pressure deficit (VPD), and to correlate with the different water potential of plants (Ψpd). This experiment was conducted in the experimental area of the Faculty of Agricultural Engineering/UNICAMP, where was installed a parcel of sugarcane, RB867515 variety was installed, and a infrared gas analyzer - IRGA LI6400XT was used in hourly scale. Based on the results, it is concluded that the values of E and Gs are positively correlated with the weather conditions and with the availability of water in the soil. Keywords: Gas Exchange, leaf water potential, photosynthetically active radiation.

SMARTIRRIGATION: REMOTE MANAGEMENT SYSTEM FOR LOCALIZED IRRIGATION AND ASPERSION

 

 

2 ABSTRACT

 

The non-rational use of irrigation systems generates waste of water and electricity. Thus, the present work illustrates the process of developing a Web System (SmartIrrigation) to remotely manage localized irrigation and sprinkler systems. To feed the system, the user inserts information of the days of the week, sectors and schedules that he / she should work, with unlimited number of schedules registered. As main results we have a system that follows good practices of IHC (Human-Computational Interface); energy saving, efficient use of water; and the convenience of the user to manage the system.

Travelling waste water screen sizing and performance, UK
Authors: Pavlov Viktor
Published: October 2018

Travelling screens have been used in the UK waste water industry for several decades and are widely renowned for their high solids capture ratio, robust design, reliable cleansing and relatively low operating and maintenance cost. However, achieving optimal performance of these screens is subject to their adequate sizing and control, combined with regular monitoring of their performance and proactive maintenance. Analysis of the photographic evidence and data gathered during a 3 months’ screen trial carried out in the UK by United Utilities at an operational waste water site revealed some key factors that could adversely affect the screen performance. It also prompted further critical analysis of the current design guidance and practices, which allowed making recommendations for improving the methods of sizing, control and maintenance of this type of screens. This resulted in some generalised conclusions being drawn which could be applied to other similar types of screens.
Hydraulic conductivity from piezocone on-the-fly: a numerical evaluation
Authors: Monforte L. , Arroyo M. , Gens A. , Carbonell J. M.
Published: October 2018

Permeability is important in many geotechnical applications. The current (cone penetration test that gathers piezometer data (CPTu)) practice to obtain permeability values relies on dissipation tests, which are frequently slow and only linked to permeability through compressibility measures. On-the-fly methods offer an alternative approach in which permeability is directly linked to CPTu penetration measurements. Several on-the-fly methods have been proposed and their applicability and relative advantages are not fully clear. Numerical effective stress simulation of CPTu testing is used here to explore in a simplified but realistic setting the relative merits of different on-the-fly methods. It is found that for partly drained materials, the original simpler relation between cone metrics and normalised permeability works reasonably well. A continuous generalisation of Elsworth and Lee method to the full permeability range is proposed, noting the connection to the backbone normalised pore-pressure curve that describes the partly drained transition of cone penetration. The importance of an undrained limit beyond which the method produces large errors is emphasised.
Properties of strain-hardening cement composites with superabsorbent polymer particles

Published: October 2018

Strain-hardening cement composites (SHCCs), characterised by strain-hardening and multiple cracking behaviours under direct tension, are generally recognised as ductile and durable construction materials. The effect of the addition of superabsorbent polymer (SAP) particles and curing condition on the mechanical performance and microstructure of binary cement-based SHCC material using ordinary cement and fly ash as the cementitious binder was investigated in this study. Three different SHCCs were designed and mixed; the SHCC mixtures were reinforced with 2% polyvinyl alcohol (PVA) fibres by volume and 1% SAP was added to one SHCC mixture. The mixtures were subjected to compressive, flexural and direct tensile tests. The sealing and healing of cracks after direct tensile tests were also monitored by a microscope. The experimental results showed that the use of fine SAP particles led to an improvement in the mechanical properties of the binary cement-based SHCC material even under air curing. The multiple cracking, ductility and crack sealing were also improved by introducing 1% SAP particles. It is thus concluded that the addition of SAP may be an effective method to improve the sustainability of binary cement-based SHCC materials.

Published: October 2018

Precast concrete sandwich panels (PCSPs) have been extensively used as a facade wall in buildings to improve thermal efficiency. The connectors that link the two concrete wythes are mainly used for in-plane shear transfer. In this study, two cross-shaped glass-fibre-reinforced polymer connectors with different section areas are proposed, with the aim of achieving optimal performance and easy construction in PCSPs. First, the pull-out and shear capacities of the connectors were evaluated. Then four PCSPs and two reinforced concrete solid panel counterparts were fabricated and tested under out-of-plane static loads in order to evaluate their flexural behaviour. The parameters investigated included the connector section area and spacing. Moreover, two-dimensional finite-element (FE) analysis was conducted to reproduce the test. The results indicate that: (a) the proposed connectors can provide considerable performance in terms of anchorage and shear capacity; (b) the failure mode of the PCSP specimens was governed by connector failure; (c) the degree of composite action in terms of ultimate strength can be obviously enhanced by increasing the connector section area and/or reducing its spacing; and (d) based on a comparison with the test results, the proposed FE model can predict the flexural behaviour of the tested PCSPs.
Macrocell corrosion mechanisms of prestressing strands in various concretes

Published: October 2018

This paper investigates the mechanisms of corrosion of seven-wire strands and the reasons for failures in detecting corrosion at early stages. As per ASTM G109 and ACI 222 R-01, a 1-year study on chloride-induced corrosion of seven-wire prestressing strands embedded in various concretes was conducted. The type of corrosion current circuits in the prismatic specimens with one top and two bottom strands was investigated. Unlike solid rebars, the concrete resistivity had a limited role on the type of corrosion circuits in strand systems, with a high probability of corrosion occurring between different wires in the top strand itself. This may be due to the flower-like geometry and the complex corrosion mechanisms within the top strand. It is recommended to perform other electrochemical measurements on the top strand – prior to making conclusions. Also, until about 6% corrosion loss is reached, the rust will fill the interstitial space between the seven wires and will not exert expansive stresses on the surrounding concrete. Hence, no staining/cracking will be visible on the concrete surface – a serious structural safety issue – necessitating frequent chloride/corrosion condition assessment of prestressed-concrete structures.
Briefing: Modular integrated construction for high-rise buildings
Authors: Pan Wei , Hon Chi Keung
Published: October 2018

This briefing paper presents the modular integrated construction (MiC) approach drawing on the literature, the theories of modularisation and production and pioneering practices. MiC is a game-changing approach introduced in Hong Kong focusing on high-density, high-rise building construction, to transform fragmented site-based construction into integrated value-driven production with the opportunity to realise enhanced quality, productivity, safety and sustainability. Wide-ranging benefits from this approach are speculated, but significant challenges co-exist. A systems framework of MiC adoption scenarios is provided with success strategies.

Authors: Duarte Meirelayne Borges
Published: October 2018

Introdução: De acordo com as Diretrizes Curriculares Nacionais, o egresso do Curso de Medicina deverá ter formação generalista, humanista, crítica e reflexiva, com senso de responsabilidade social e compromisso com a cidadania, como promotor da saúde integral do ser humano. Diversas doenças são estigmatizadas na nossa sociedade contemporânea, o que resulta em deterioração da identidade social, agravamento das limitações funcionais e redução das possibilidades de reabilitação. Objetivo: Relatar a experiência da abordagem do Estigma Social das Doenças no Curso de Medicina. Metodologia: Após sensibilização com um documentário sobre o estigma social da hanseníase, seguida por breve exposição dialogada sobre o tema, os discentes de três turmas do quarto semestre do Curso de Medicina (50 alunos/turma) foram convidados a elaborar mídias audiovisuais combatendo o estigma social de quaisquer doenças estigmatizadas, para divulgação nas redes sociais. Resultados: Os discentes se revelaram bastante sensibilizados com o tema, partilhando suas impressões e alguns depoimentos sobre o estigma vivenciado por si mesmos e por seus familiares portadores de doenças estigmatizantes.Todas as 30 equipes de 5 alunos aderiram à proposta, de caráter facultativo, sendo produzidas 30 mídias (flyers ou vídeos) que, através das redes sociais, poderão ajudar à sociedade a desconstruir o estigma social das doenças. Conclusão: A metodologia utilizada mostrou-se eficaz na sensibilização dos estudantes de Medicina sobre o tema e culminou na produção de mídias audiovisuais, veiculáveis nas redes sociais, como estratégia de redução do estigma social das doenças e promoção do reconhecimento da cidadania e da dignidade humana dos portadores de tais doenças.
