FÚTBOL, PRENSA E IDENTIDADES NACIONALES EN ESPAÑA, 1975-2017
Authors: Simón Juan Antonio
Published: April 2019

O objetivo desta pesquisa foi analisar o papel desempenhado pelo futebol como meio para a construção, configuração e fortalecimento das identidades nacionais na Espanha entre 1975 e 2017. No âmbito metodológico, revisaram-se a bibliografia e as principais revistas e jornais espanhóis, tanto de esportes quanto de informação geral desse período. Os principais resultados obtidos nos mostram como a imprensa reescreveu as várias narrativas sobre a identidade nacional espanhola desde os últimos anos, tornando-se a ferramenta ideal para associar certos estereótipos e mitos à seleção espanhola e aos principais clubes de futebol. Do mesmo modo, a relação entre o futebol e a imprensa também desempenhou um papel fundamental na criação e transformação dos discursos identitários na Catalunha e no País Basco durante as últimas décadas.

O objetivo do presente estudo foi conhecer a influência que a mídia tem sobre a construção das subjetividades corporais dos futuros professores de Educação Física (EF). Participaram oito futuros professores (cinco homens e três mulheres). A foto-elicitação foi utilizada como técnica de análise e as entrevistas foram usadas como instrumentos de coleta de dados. Os resultados refletiram como a maneira de conceber o assunto da EF é claramente condicionada pelo protótipo do corpo do professor. É o músculo nos homens e o delgado e definido nas mulheres o mais valorizado, algo que está associado ao modelo ideal exaltado na mídia. Eles reconhecem que o corpo é sua ferramenta de trabalho e sua maneira de se apresentar a outros. Enfatizamos a importância de analisar o corpo a partir de uma abordagem pedagógica ligada à criação da identidade profissional dos futuros professores.

The mobile ad-hoc networks (MANET) are those whose nodes have mobility, energy restriction and operate simultaneously as end systems and router. One of the main problems found in MANETs is the occurrence of selfish nodes, which are those that refuse to route packets for other nodes. To address the issue of selfish nodes in MANETs and improve the flow of traffic in these networks, this paper proposes an extension to the OLSR protocol, based on Fuzzy logic, called OLSR Fuzzy Cost (OLSR -FC). Using the NS-2 simulator, the OLSR-FC proposal was compared to other extensions of OLSR protocol (e.g., OLSR-ETX, OLSR-ML e OLSR-MD) concerning the performance metrics: packet loss, end-to-end delay, Jitter, power consumption, routing overhead and throughput. The results showed that OLSR-FC obtains better performance than the evaluated extensions, avoiding selfish nodes and selecting routes whose links have little packet losses.

Authors: Sultan Asriana , Ida Nur , Ismail Isriany
Published: April 2019

Ketoprofen is included in the Class II of Biopharmaceutical Classification System (BCS) which has low solubility. Low solubility will affect the dissolution rate and the dissolved concentration, so the absorption and bioavailability are low as well. Several studies have been conducted to improve the solubility and the dissolution of drugs from these group, such as by solid dispersion system. This study aims to determine the effect of polyvinyl alcohol (PVA) on the dissolved concentration of ketoprofen in solid dispersion and in physical mixture, and to decidethe optimum formula.Solid dispersion and physical mixture of ketoprofen - PVA were formulated with the ratio of 1:1, 1:2 and 1:4, and then compared with the standard ketoprofen. Evaluation of solid dispersion was performed by the intervention test of PVA as a matrix on the maximum wavelength of standard ketoprofen using a UV-Vis spectrophotometer and the dissolution test in artificial gastric fluid media without pepsin using a basket stirrer at pH ± 1,2, the temperature of 37 ± 0.5ºC, and device speed of 50 rpm. The sample was collected at 10, 20, 30, 45, and 60 minutes. The amount of dissolved ketoprofen was determined by a UV-Vis spectrophotometer at a wavelength of 260 nm. The results showed that there was no shifting on maximum wavelength point in both solid dispersions and physical mixtures. The dissolved ketoprofen concentration that was represented in solid dispersion was greater than in physical mixture and standard ketoprofen. The highest dissolved ketoprofen concentration was indicated in solid dispersion formula with the ratio of 1:1.
Review: Metode Peningkatan Kecepatan Disolusi Dikombinasi Dengan Penambahan Surfaktan

Published: April 2019

Dissolution and solubility rates are very important parameters in designing a pharmaceutical dosage form, especially for oral drug administration. Oral drugs that have low dissolution rates often require high doses loading to improve the absorption and effectiveness  in order to achieve therapeutic concentration. The increasing of drug dose is a less safe alternative solution, therefore researchers have developed physics, chemistry, and other modification  in order to increase dissolution rate. These methods such as salt formation, prodrug formation, particle size reduction (micro-crystallization), co-grinding, crystal modification, micellar solubilization and complex formation, solid dispersion and self emulsifying. This review paper will focus on different methods that will be compared with the present of surfactant in these methods. The present of surfactants was able to overcome the limitation of each methods with a mechanism for reducing surface tension, micellar formation, reducing contact angle and increasing of wetting behaviour. Therefore, the present of surfactant in modification of drug dosage form could be considered to increase dissolution rate in order to achieve therapeutic effect.

Published: April 2019

Lycopene is a carotenoid group easily damaged due to the oxidation process (light, oxygen and temperature) and isomerization during storage. This damage can be minimized by microencapsulation processes. The objective of this study was to develop novel microencapsulation of lycopene extracts from tomato fruit by solvent evaporation method using ethyl cellulose as wall materials and to select the optimum formulation. Three microcapsule formulations were prepared containing the ratio of lycopene and ethyl cellulose (L:ES) of 1:1, 1:2 and 1:3. The morphology of the microcapsules was analysed by optical microscopy and scanning electronic microscopy. The encapsulation efficiency, particle size, recovery yield and moisture content were also examined. The result showed that all microcapsule formula were aggregated and irregular in shape with encapsulation efficiency of 6.13- 19.43%, moisture content of 1,63- 7,52%, recovery yield of 81-98,12% and particle size of 46,2-86µm. Microcapsule with a ratio 1:3 (L:ES) was the most optimum formula based on a maximum encapsulation efficiency than the others
Inline weld depth measurement for high brilliance laser beam sources using optical coherence tomography
Authors: Schmoeller Maximilian , Stadter Christian , Liebl Stefan , Zaeh Michael F.
Published: April 2019

As a result of the rapidly growing importance of applications in electro mobility that require a precisely defined laser weld depth, the demand for inline process monitoring and control is increasing. To overcome the challenges in process data acquisition, this paper proposes the application of a novel sensor concept for deep penetration laser beam welding with high brilliance laser sources. The experiments show that optical coherence tomography (OCT) can be used to measure the weld depth by comparing the distance to the material surface with the distance to the keyhole bottom measured by the sensor. Within the presented work, the measuring principle was used for the first time to observe a welding process with a highly focused laser beam source. First, a preliminary experimental study was carried out to evaluate the influence of the angle of incidence, the material, and the weld joint geometry on the quality of the sensor signal. When using a multimode fiber laser with a focus diameter of 320 μm, the measurements showed a distinct behavior for aluminum and copper. The findings about the measurement signal properties were then applied to laser beam welding with a single-mode fiber laser with a spot diameter of only 55 μm. The spot diameter of the OCT measuring beam was about 50 μm and thus only slightly smaller than that of the single-mode processing beam. A wide variety of tests were carried out to determine the limits of the measurement procedure. The results show that the application of OCT allows inline monitoring of the weld depth using both a multimode and a highly focused single-mode laser beam. In addition, various influences on the signal were identified, e.g., the material-specific melt pool dynamics as well as several characteristic reflection and absorption properties.
Investigation on the effect of laser remelting for laser cladding nickel based alloy
Authors: Zhao Yanzhe , Sun Jie , Guo Kai , Li Jianfeng
Published: April 2019

Laser cladding is a recently developed additive manufacturing technique, which is widely used in remanufacturing and sustainable manufacturing fields. However, the surface roughness of laser cladding layer often fails to meet the tribological functions and assembly requirements. In order to improve the surface finish quality of laser cladding, various techniques such as manual polishing, grinding, abrasive blasting, and chemical polishing were adopted. However, these methods have certain disadvantages, such as secondary positioning and polluting the environment. Laser remelting is an eco-friendly technology, which is based on remelting of a thin surface layer and can improve surface quality without the secondary positioning. In this paper, the high-power continuous-wave carbon dioxide laser was first used for preparing laser cladding layer of nickel-based alloy and then used for laser remelting process. Design of experiments based on orthogonal arrays was employed for optimization of process parameters. Both surfaces of laser cladding and laser remelting, as well as the cross-sectional subsurface, were analyzed to investigate the variation of surface roughness. Scanning electron microscopy and energy dispersive spectrometer were used to analyze the microstructure of the remelted sample. It was shown that the average surface roughness of laser cladding layer was reduced more than 2 μm after laser remelting process. Microstructure and microhardness of laser remelting zone were investigated in order to examine the thermal effect of laser remelting processing on the laser cladding layer. It can be induced that laser remelting process is an effective method to improve the surface quality of laser cladding.
Laser metal deposition strategies for repairing flat and notched substrates made of Ni-based single crystalline superalloys

Published: April 2019

Laser metal deposition, or laser cladding, has been applied to repair and manufacture turbine blades as well as other superalloy components. In some cases, these applications can lower parts manufacturing and maintenance costs, or even increase engine efficiency; therefore, they attract considerable interest from the aerospace industry. However, the single crystalline (SX) repair of Ni-based superalloy parts is still a technology under development. Recent works aimed to understand the solidification phenomena present in a laser-formed melt pool or to achieve SX depositions through epitaxial solidification computational modeling. Here, to attain high SX depositions on flat and notched substrates without the need of such sophisticated methods, a previously developed design of experiments (DoE) for laser remelting was used to produce SX clad tracks. New data related to this DoE are presented, describing its characteristics and possible improvement. Furthermore, a remolten clad track extracted from the DoE was used as a basis to three cladding strategies applied on flat (010) substrates. From such depositions, one strategy was chosen to also be applied on a (110) substrate, yielding insights on the interaction between substrate orientation, cladding strategy, and track parameterization adequacy. The depositions were evaluated through electron backscatter diffraction mapping and profiling, as well as oriented-to-misoriented observation. Finally, the clad tracks’ disposition of a successful SX deposition was used to determine a notch profile. The notch profile was then machined into a substrate, simulating a crack repair, and filled accordingly. This extrapolation from flat to notch was based on simple geometrical considerations and resulted in an SX notch fill. Therefore, showing evidence that the sequence of considerations taken is a promising approach to define notch geometry for SX repair. The cladding strategies evaluated, the verified DoE, and the approach taken for notch filling may be of use to researchers and engineers when planning more sophisticated procedures that aim the repair of Ni-based SX components.

Perjudian adalah suatu bentuk patologi sosial. Perjudian menjadi ancaman yang nyata atau potensiil terhadap norma-norma sosial sehingga bias mengancam berlangsungnya ketertiban sosial. Dengan demikian perjudian dapat menjadi penghambat pembangunan nasional yang beraspek material-spiritual. Oleh karena itu perjudian harus ditangani dengan cara rasional. Salah satu usaha yang rasional tersebut adalah dengan pendekatan kebijakan penegakan serta proses penindakan terhadap pelaku hukum pidana. Permasalahan yang dihadapi yaitu apakah kebijakan hukum pidana di Indonesia yang ada saat ini telah memadai dalam rangka menangani kasus perjudian dan bagaimana proses penyidikan hukum pidana. Serta bagaimana proses penanganan hukum pidana di masa yang akan dating untuk menangani tindak pidana perjudian. Metode penelitian yang digunakan adalah deskriptif kualitatif, yaitu dengan mengkaji atau menganalisis data sekunder yang berupa bahan-bahan hukum sekunder dengan memahami hukum sebagai perangkat peraturan atau norma-norma positif di dalam system perundang-undangan yang mengatur mengenai kehidupan manusia.

Tingkat partisipasi masyarakat menjadi salah satu satu tolak ukur keberhasilan pelaksanaan Pemilu. Pada PILKADA serentak tahun 2018 di 171 daerah di Indonesia,tercatat partisipasi pemilih mencapai 73,24 % dari jumlah DPT yang lebih kecil dibanding partisipasi pemilih Pilkada tahun 2017 yang mencapai 74 %. (sumber : data KPU RI).

Berbagai cara dilakukan untuk mendongkrak tingkat partisipasi masyarakat termasuk Pemilih Remaja (pemilih pemula). Mengajak kaum milenial lebih aktif dalam Pemilu membutuhkan metode dan pendekatan yang tepat hingga mampu meningkatkan partisipasi mereka dalam Pemilu, salah satunya melalui pendidikan demokrasi dan HAM yang menjadi bagian pembelajaran Pendidikan Kewarganegaraan.Penelitian ini bertujuan mengetahui seberapa besar dampak perolehan Pendidikan kewarganegaraan terhadap peningkatan partisipasi pemilih remaja pada Pemilu.

Dari penelitian yang dilakukan terhadap 200 orang pemilih remaja di 3 Sekolah Menengah Atas dan 2 Perguruan Tinggi di Kota Medan, menunjukkan adanya dampak (pengaruh) yang signifikan pendidikan kewarganegaraan terhadap peningkatan partisipasi pemilih remaja dalam Pemilu. Penelitian mengambil studi kasus pada Pemilihan Gubernur dan Wakil Gubernur Sumatera Utara Tahun 2018 ini menunjukkan terdapat hubungan antara variabel Pendidikan Kewarganegaraan dengan tingkat Partisipasi Pemilih Remaja dan memiliki korelasi yang kuat. Terdapat koefisien 0,659 dan termasuk ke dalam korelasi kuat (karena nilainya lebih dari 0,5) maka tanda pada koefisien korelasi adalah positif, artinya semakin baik Pendidikan Kewarganegaraan yang diterima oleh Pemilih Remaja (Pemula) maka tingkat Partisipasinya juga akan semakin tinggi.

OBJECTIVE

To evaluate long-term outcomes and identify factors associated with death or the need for revision surgery in dogs with permanent tracheostomies (PTs).

DESIGN

Retrospective cohort study.

ANIMALS

69 client-owned dogs that received a PT between January 2002 and June 2016 at 1 of 4 veterinary teaching hospitals.

PROCEDURES

Medical records were reviewed, and data extracted included signalment, history, clinical signs, radiographic and laryngeal examination findings, presence of esophageal abnormalities, date and reason for receiving a PT, postoperative complications, cause of death, and survival time. Dogs surviving < 2 weeks after receiving a PT were excluded.

RESULTS

Major complications occurred in 42 of 69 (61%) dogs, with aspiration pneumonia (13 [19%]), skinfold occlusion (13 [19%]), and stoma stenosis (12 [17%]) being most common. Revision surgery was performed in 24 of 69 (35%) dogs, most commonly because of stoma stenosis or skinfold occlusion (9/24 [38%] each). Brachycephalic dogs were more likely (OR, 3.5; 95% confidence interval, 1.2 to 10.2) to require revision surgery than were nonbrachycephalic dogs. The overall median survival time was 1,825 days, and dogs that received corticosteroids before receiving a PT, had tracheal collapse, or were older had shorter survival times.

CONCLUSIONS AND CLINICAL RELEVANCE

Results of the present study indicated that creation of a PT was a viable treatment option for obstructive upper airway diseases in dogs and that long-term survival after receiving a PT was possible; however, a PT may not reduce the risk of aspiration pneumonia in dogs.

Uma movimentação cultural punk de forte inclinação ao anarquismo surgiu na década de 1990 na cidade de São Paulo, o chamado anarcopunk, em que atuou expressivo contingente de mulheres e no qual houve, em consequência de sua politização, a fomentação da militância feminista e de perspectivas pró-feminismos. Tais aspectos estão expressos em letras de músicas de duas das bandas que compunham o cenário anarcopunk e, posteriormente, raw punk na capital paulista: Pós-Guerra e Luta Armada. Partiremos da apreciação do cenário no qual se inseriam as bandas citadas, objetivando a investigação de alguns aspectos do contexto histórico em que essas bandas atuaram, pensando a identidade punk feminina que se apresenta em duas canções selecionadas.

Energy expenditure and dietary intake of female collegiate tennis and soccer players during a competitive season
Authors: Yli-Piipari Sami
Published: April 2019

This study examined energy
expenditure, dietary behavior, and energy balance of female tennis and soccer
student-athletes during a competitive season. A sample of 18 (Mage=19.86±1.35 years)
Division I female collegiate student-athletes (5 tennis and 13 soccer players)
were followed for four days, i. e., during one game/match, two practice
sessions, and one recovery day. Physical activity was assessed with
accelerometers and dietary behavior with daily food logs. Daily energy
expenditure for the game/match, practice, and rest days was 2,848±304kcal,
2,622±248kcal, and 1,833±959kcal, respectively, with a statistically
significant main effect (F[2,16]=82.291,
p<.001, η2=.91). Daily
dietary intake ranged from 1,833±959 to 1849±371kcal, with no significant
interaction between different days. There were no sport specific differences in
energy expenditure or dietary behaviors. Athletes consumed 4.30±2.07 g/kg
carbohydrates, 1.57±.98 g/kg protein, and 1.27±.80 g/kg fats daily. There was a
significant main effect in dietary intake (F[2,16]=7.311,
p=.006, η2=.48), with a difference
between game/match and recovery days (t[17]=3.83,
p=.001, d=1.19). This study showed a negative energy balance among female
student-athletes. The findings indicate that the lack of carbohydrate intake
during game/match days contributed to this energy deficit.

Published: April 2019

This investigation examined the interactive effect of body-weight
(BW) exercises and vibration on cardiometabolic responses. Fourteen subjects performed
a BW exercise protocol with (BW+V) and without (BW‒V) vibration in a randomized
order. The BW exercise protocol consisted of three circuits of eight
calisthenics-based exercises including prisoner squat, push-up, isometric
squat, reverse dip, lunge, flutter kicks, isometric lunge, and T push-up. Vibratory
frequency and amplitude were set at 40 Hz and 4 mm, respectively. Oxygen uptake
(VO2), heart rate (HR), expired ventilation (VE), and
blood lactate [La] were determined during the protocol and 30-minute recovery. The
mean VO2 reached 48% and 50% of VO2max and the mean HR
reached 80% and 83% of HRmax in BW‒V and BW+V, respectively. During the
protocol, while the mean VE was greater (p=.031) in BW+V than BW‒V,
no differences were seen for VO2 and HR between the two conditions. During
recovery, while mean VO2 was greater (p=.002) in BW+V than BW-V, no
differences were seen for VE and HR between the two conditions. [La]
values were significantly elevated but remained similar between the two
conditions. Exercise-specific VO2 was higher during the prisoner
squat (p=.003) and isometric squat (p=.042) in BW+V than BW‒V, while no differences
in VO2 were observed for all other exercises. Performing three
circuits of eight BW exercises in a rapid-and-intense manner produced a
sufficient increase in cardiometabolic responses. Metabolic potentiation
associated with combining vibration with BW exercises seemed to be influenced
by how the exercises were carried out on a vibration plate.

Udang vaname  merupakan salah satu jenis udang yang banyak dibudidayakan di Indonesia. Udang ini banyak digemari dan memiliki nilai ekonomis yang cukup tinggi, bahkan menjadi primadona dari Indonesia. Akan tetapi, kegiatan budidaya udang menghadapi permasalahan terkait faktor lingkungan, penyakit, pertumbuhan yang lambat, serta kematian massal. Hal ini berakibat menurunkan tingkat produktivitas udang vaname. Salah satu pendekatan alternatif yang dapat dilakukan untuk mengatasi permasalahan tersebut yaitu dengan penambahan prebiotik pada pakan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan prebiotik yang berbeda pada pakan terhadap pertumbuhan udang vaname (Litopanaeus vannamei). Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) yaitu dengan 4 perlakuan dan 3 ulangan, perlakuannya adalah Kontrol K ( pakan  tanpa  prebiotik), P1 (pakan pellet dengan penambahan prebiotik ubi  2%), P2 (pakan pellet dengan penambahan prebiotik kentang 2%), P3 ( pakan pellet dengan penambahan prebiotik ubi 1% dan  kentang 1%). Data yang diperoleh dianalisa menggunakan analysis of variance (ANOVA) dengan tingkat signifikan 5%. Hasilnya menunjukkan bahwa tidak ada perbedaan yang signifikan antara perlakuannya untuk tingkat laju pertumbuhan spesifik, bobot mutlak, rasio konversi pakan, dan pertumbuhan mutlak.

Penelitian ini bertujuan untuk mendeteksi dan mengkuantifikasi jumlah bakteri penghasil enzim fitase dari saluran pencernaan ikan nila. Ada dua jenis sample yang digunakan, yakni ikan yang dibudidaya dan ikan liar. Hasil penelitian menunjukkan bakteri penghasil enzim fitase hanya dapat dideteksi dari saluran pencernaan ikan budidaya. Sedangkan, pada saluran pencernaan ikan nila liar tidak ditemukan adanya kelompok bakteri penghasi enzim tersebut. Dari total jumlah bakteri yang bersimbiosis dengan saluran pencernaan ikan nila dibudidaya (7.8 x 107 CFU/g), jumlah bakteri penghasil enzim fitase sebanyak 2.6 x 106 CFU/g atau sekitar 3.31%. Hasil penelitian ini mengkonfirmasi adanya bakteri penghasil enzim fitase di saluran pencernaan ikan nila budidaya. Uji lanjut untuk mengetahui kuantitas enzim fitase yang dihasilkan di saluran pencernaan sangat diperlukan untuk mengetahui jumlah asam fitat maksimum yang dapat dicerna. Selain itu, bakteri tersebut harus diidentifikasi untuk dapat mengetahui sumbernya.

An Interspecies Internet? Thinking and Acting Feminist - Animal Rights Discourse Online
Authors: Jones Rebecca
Published: April 2019

As contemporary feminist discourse continues to utilize online and digital media and technologies as platforms and tools for debate and information sharing, the reality of who -and what - has access and makes contributions to this discourse is changing. The perception of online and digital communication and debate as accessible, intersectional and democratizing forces has also meant that the conceived relationship between theoretical discourse and feminist praxis in a global forum has been made more mutable, and the distinctions between what is theory and what is praxis have become more blurred. Whether we regard digital media as trans or post-human, disembodied or decentralized, it does at least represent a form of conversation that blurs the boundaries of how we communicate, who (and what) is considered to have subjectivity, the impact of geographical location and embodiment and corporeality. These have also underpinned feminist animal rights and feminist vegetarian/vegan discourse, especially around our feminist understanding of what it means to be human. This paper references feminist vegetarian, feminist-vegan and ecofeminist theory alongside theoretical work from animal studies across a range of disciplines to analyze feminist intersections with animal rights and veganism. In doing this I hope to offer an introduction to how online context influences feminist animal rights discourse. By considering this topic through a lens of ecofeminist and vegetarian/vegan feminist theory, what we think about when we think about ‘the animal’, and an examination of the role and function of digital media in feminist discourse, this paper offers some reflections on the online contribution being made to feminist animal rights and vegan discourse, and how digital media are shaping and influencing this discourse and its wider impact.

Developments and advancements in the ICT environment has led to high increase in electronic commerce. Cyber contractual disputes also emerge rapidly and this challenge the traditional consumer protection systems in terms of redressal and remedies. To protect consumers rights and interests, ADR mechanisms can be used which can overcome the difficulties confronted in the traditional litigation process. Dispute resolution in internet contracts can take place online either entirely or partly. There are various mechanisms available to resolve disputes which can protect disputants’ interests and rights absolutely. As the cyber environment usage continues to expand, it is utmost important to design effective mechanisms for resolving online commercial disputes because traditional adjudicatory process can be time consuming, expensive and may raise jurisdictional problems. Though the current trends and practice in the field of online dispute resolution exists, it appears that there are various aspects relating to which are yet to be clarified. This article aims to present a national and international scientific literature review on the models of Dispute Resolution mechanisms, discusses the use of Alternative dispute resolution systems (including ODR), types of procedure and mechanisms adapted for dealing with commercial disputes in India. It also looks into the international frameworks available with redressal systems and its effectiveness in dealing with cross border disputes.

Authors: Muhammad Dr. Nasiruddeen
Published: April 2019

The maritime industry had for long, recognized the relevance and significance of arbitration as a method of dispute resolution. The industry has been utilizing quasi-ad-hoc mechanism in conducting its arbitrations. Of recent, the industry is witnessing a phenomenal shift from the traditional quasi –ad-hoc mechanism to institutional mechanisms whereby special administrative centers dedicated to the resolution maritime disputes are being established to administer the dispute resolution. Recently, the government of Dubai in the United Arab Emirates, pursuant to Decree No (14) of 2016 had established Emirates Maritime Arbitration Center with the objective of settling local and international maritime disputes using alternative dispute resolution methods. The paper investigates the two approaches of ad-hoc vs institutionalism of administering dispute settlement in the maritime industry from a tailored analytical tool of ‘access to arbitration’ mirrored on the well-established legal principle of access to justice.

Published: April 2019

En este artículo se analizan los impactos en la accesibilidad territorial en Andalucía de las actuaciones en carreteras planificadas por la Consejería de Fomento y Vivienda de la Junta de Andalucía. Para ello, se ha desarrollado una herramienta informática basada en Sistemas de Información Geográfica, y se han calculado una serie de indicadores de accesibilidad y cohesión territorial. Para llevar a cabo el análisis de los efectos del Plan de Infraestructuras para la Sostenibilidad del Transporte en Andalucía, se han contemplado dos escenarios: uno sin las actuaciones previstas y otro con todas las actuaciones planeadas implementadas. También se han estudiado los efectos de dicho plan sobre la accesibilidad a hospitales, universidades y centros logísticos, así como las mejoras inducidas por cuatro importantes actuaciones concretas. Los resultados muestran mejoras significativas, como una reducción media en los tiempos de viaje del 3,6%, y que las actuaciones del plan de infraestructuras potencian la cohesión territorial.
