Authors: Basok B.I. , Baseyev E.T.
Published: September 2018

The communal heat power engineering of Ukraine and its main area - the heat supply of the settlements of Ukraine - is the main consumer of primary energy resources (more than 60% of the total energy balance of the country, mainly imported natural gas). At the same time, this sector has the greatest potential for energy saving if measures and mechanisms are used to increase the efficiency of energy use, first of all with energy supply in buildings (thermal losses here reach up to 40%). Low energy efficiency of heat supply is the main reason for high tariffs for the consumer of housing and communal services and the challenge of social tension. Increasing energy efficiency is a basic condition for national economic, environmental and social stability, a requirement for the safety of life and a guarantee of the entire national security of the country. An overview of technological, organizational and socio-economic innovations for increasing energy efficiency of buildings is presented. Innovative equipment and technologies for increasing the energy efficiency of buildings and innovative engineering systems for their energy supply have been carried out at ITTP NAS of Ukraine. The method of determination of energy efficiency indicators of buildings, enclosing structures of buildings and the practice of conducting energy audits with the use of such diagnostic center measures as demonstration building of the "zero energy" constructed on the territory of ITT of NAS of Ukraine with energy supply from renewable energy sources (heat of soil, insolation, wind). Such a demonstration facility serves as a scientific and methodological center for training students of heat energy specialties, as well as the training of specialists involved in the development of energy efficient energy supply technologies for buildings and their energy audit. On the problems of increasing energy efficiency of the building sector in the near future, the main objectives of scientific research, subjects of fundamental, applied research, subjects, methods and tools of such research were determined.
The Equality of Women
Authors: Hatcher John
Published: September 2018

The Bahá’í teachings simultaneously assert the equality of men and women while advocating in some cases distinct duties according to gender. Since the Bahá’í Faith also teaches that religious convictions should be examined by the “standards of science,” this ostensible paradox invites careful study. At the heart of the response to this query is the Universal House of Justice statement that “equality between men and women does not, indeed physiologically itcannot, mean identity of functions.” To appreciate and to accept this thesis that there can be gender distinction, even insofar as the assignment of fundamental tasks is concerned, without any attendant diminution in the role of women, we must turn to statements in the Bahá’í writings about the complementary relationship between men and women. Through a careful consideration of this principle, we can discover how there can indeed be gender distinction without inequality in status or function.
Translating the Bahá’í Writings
Authors: Volker Craig
Published: September 2018

Although the difficulties of translating the holy Word are recognized, Bahá’í institutions have always stressed the importance of translation. No approach to biblical or quranic translation corresponds completely to the Bahá’í ideal, just as no former religious leader combined Shoghi Effendi’s unique dual role as Guardian and translator. Bahá’í institutions have defined the most salient theoretical issues relating to Bahá’í translation. In translating the Bahá’íwritings, faithfulness to the original text is paramount. This is defined as reflecting the beauty of the original and accurately conveying the concepts of the original. Consultation is an integral part of the translation process, and translations of scripture are seen as a tool for education. Bahá’í translators today face a number of practical problems caused by a lack of resources, cultural differences, and linguistic underdevelopment.
The medial wall of the cavernous sinus. Part 1: Surgical anatomy, ligaments, and surgical technique for its mobilization and/or resection
Authors: Truong Huy Q. , Lieber Stefan , Najera Edinson , Alves-Belo Joao T. , Gardner Paul A. , Fernandez-Miranda Juan C.
Published: September 2018

OBJECTIVE

The medial wall of the cavernous sinus (CS) is often invaded by pituitary adenomas. Surgical mobilization and/or removal of the medial wall remains a challenge.

METHODS

Endoscopic endonasal dissection was performed in 20 human cadaver heads. The configuration of the medial wall, its relationship to the internal carotid artery (ICA), and the ligamentous connections in between them were investigated in 40 CSs.

RESULTS

The medial wall of the CS was confirmed to be an intact single layer of dura that is distinct from the capsule of the pituitary gland and the periosteal layer that forms the anterior wall of the CS. In 32.5% of hemispheres, the medial wall was indented by and/or well adhered to the cavernous ICA. The authors identified multiple ligamentous fibers that anchored the medial wall to other walls of the CS and/or to specific ICA segments. These parasellar ligaments were classified into 4 groups: 1) caroticoclinoid ligament, spanning from the medial wall and the middle clinoid toward the clinoid ICA segment and anterior clinoid process; 2) superior parasellar ligament, connecting the medial wall to the horizontal cavernous ICA and/or lateral wall of the CS; 3) inferior parasellar ligament, bridging the medial wall to the anterior wall of the CS or anterior surface of the short vertical segment of the cavernous ICA; and 4) posterior parasellar ligament, which anchors the medial wall to the short vertical segment of the cavernous ICA and/or the posterior carotid sulcus. The caroticoclinoid ligament and inferior parasellar ligament were present in most CSs (97.7% and 95%, respectively), while the superior and posterior parasellar ligaments were identified in approximately half of the CSs (57.5% and 45%, respectively). The caroticoclinoid ligament was the strongest and largest ligament, and it was typically assembled as a group of ligaments with a fan-like arrangement. The inferior parasellar ligament was the first to be encountered after opening the anterior wall of the CS during an interdural transcavernous approach.

CONCLUSIONS

The authors introduce a classification of the parasellar ligaments and their role in anchoring the medial wall of the CS. These ligaments should be identified and transected to safely mobilize the medial wall away from the cavernous ICA during a transcavernous approach and for safe and complete resection of adenomas that selectively invade the medial wall.

OBJECTIVE

The epileptogenic zones in some patients with temporal lobe epilepsy (TLE) involve regions outside the typical extent of anterior temporal lobectomy (i.e., “temporal plus epilepsy”), including portions of the supratemporal plane (STP). Failure to identify this subset of patients and adjust the surgical plan accordingly results in suboptimum surgical outcomes. There are unique technical challenges associated with obtaining recordings from the STP. The authors sought to examine the clinical utility and safety of placing depth electrodes within the STP in patients with TLE.

METHODS

This study is a retrospective review and analysis of all cases in which patients underwent intracranial electroencephalography (iEEG) with use of at least one STP depth electrode over the 10 years from January 2006 through December 2015 at University of Iowa Hospitals and Clinics. Basic clinical information was collected, including the presence of ictal auditory symptoms, electrode coverage, monitoring results, resection extent, outcomes, and complications. Additionally, cases in which the temporal lobe was primarily or secondarily involved in seizure onset and propagation were categorized based upon how rapidly epileptic activity was observed within the STP following seizure onsets: within 1 second, between 1 and 15 seconds, after 15 seconds, and not involved.

RESULTS

Fifty-two patients underwent iEEG with STP coverage, with 1 STP electrode used in 45 (86.5%) cases and 2 STP electrodes in the other cases. There were no complications related to STP electrode placement. Of 42 cases in which the temporal lobe was primarily or secondarily involved, seizure activity was recorded from the STP in 36 cases (85.7%): in 5 cases (11.9%) within 1 second, in 5 (11.9%) between 1 and 15 seconds, and in 26 (61.9%) more than 15 seconds following seizure onset. Seizure outcomes inversely correlated with rapid ictal involvement of the STP (Engel class I achieved in 25%, 67%, and 82% of patients in the above categories, respectively). All patients without ictal STP involvement achieved seizure freedom. Only 4 (11.1%) patients with STP ictal involvement reported auditory symptoms.

CONCLUSIONS

Ictal involvement of the STP is common even in the absence of auditory symptoms and can be effectively detected by the STP electrodes. These electrodes are safe to implant and provide useful prognostic information.
Elucidating the kinetics of sodium fluorescein for fluorescence-guided surgery of glioma
Authors: Folaron Margaret , Strawbridge Rendall , Samkoe Kimberley S. , Filan Caroline , Roberts David W. , Davis Scott C.
Published: September 2018

OBJECTIVE

The use of the optical contrast agent sodium fluorescein (NaFl) to guide resection of gliomas has been under investigation for decades. Although this imaging strategy assumes the agent remains confined to the vasculature except in regions of blood-brain barrier (BBB) disruption, clinical studies have reported significant NaFl signal in normal brain tissue, limiting tumor-to-normal contrast. A possible explanation arises from earlier studies, which reported that NaFl exists in both pure and protein-bound forms in the blood, the former being small enough to cross the BBB. This study aims to elucidate the kinetic binding behavior of NaFl in circulating blood and its effect on NaFl accumulation in brain tissue and tumor contrast. Additionally, the authors examined the blood and tissue kinetics, as well as tumor uptake, of a pegylated form of fluorescein selected as a potential optical analog of gadolinium-based MRI contrast agents.

METHODS

Cohorts of mice were administered one of the following doses/forms of NaFl: 1) high human equivalent dose (HED) of NaFl, 2) low HED of NaFl, or 3) pegylated form of fluorescein. In each cohort, groups of animals were euthanized 15, 30, 60, and 120 minutes after administration for ex vivo analysis of fluorescein fluorescence. Using gel electrophoresis and fluorescence imaging of blood and brain specimens, the authors quantified the temporal kinetics of bound NaFl, unbound NaFl, and pegylated fluorescein in the blood and normal brain tissue. Finally, they compared tumor-to-normal contrast for NaFl and pegylated-fluorescein in U251 glioma xenografts.

RESULTS

Administration of NaFl resulted in the presence of unbound and protein-bound NaFl in the circulation, with unbound NaFl constituting up to 70% of the signal. While protein-bound NaFl was undetectable in brain tissue, unbound NaFl was observed throughout the brain. The observed behavior was time and dose dependent. The pegylated form of fluorescein showed minimal uptake in brain tissue and improved tumor-to-normal contrast by 38%.

CONCLUSIONS

Unbound NaFl in the blood crosses the BBB, limiting the achievable tumor-to-normal contrast and undermining the inherent advantage of tumor imaging in the brain. Dosing and incubation time should be considered carefully for NaFl-based fluorescence-guided surgery (FGS) of glioma. A pegylated form of fluorescein showed more favorable normal tissue kinetics that translated to higher tumor-to-normal contrast. These results warrant further development of pegylated-fluorescein for FGS of glioma.

Published: September 2018

OBJECTIVE

Pituitary adenomas often invade the medial wall of the cavernous sinus (CS), but this structure is generally not surgically removed because of the risk of vascular and cranial nerve injury. The purpose of this study was to report the surgical outcomes in a large series of cases of invasive pituitary adenoma in which the medial wall of the CS was selectively removed following an anatomically based, stepwise surgical technique.

METHODS

The authors’ institutional database was reviewed to identify cases of pituitary adenoma with isolated invasion of the medial wall, based on an intraoperative evaluation, in which patients underwent an endoscopic endonasal approach with selective resection of the medial wall of the CS. Cases with CS invasion beyond the medial wall were excluded. Patient complications, resection, and remission rates were assessed.

RESULTS

Fifty patients were eligible for this study, 15 (30%) with nonfunctional adenomas and 35 (70%) with functional adenomas, including 16 growth hormone–, 10 prolactin-, and 9 adrenocorticotropic hormone (ACTH)–secreting tumors. The average tumor size was 2.3 cm for nonfunctional and 1.3 cm for functional adenomas. Radiographically, 11 cases (22%) were Knosp grade 1, 23 (46%) Knosp grade 2, and 16 (32%) Knosp grade 3. Complete tumor resection, based on intraoperative impression and postoperative MRI, was achieved in all cases. The mean follow-up was 30 months (range 4–64 months) for patients with functional adenomas and 16 months (range 4–30 months) for those with nonfunctional adenomas. At last follow-up, complete biochemical remission (using current criteria) without adjuvant treatment was seen in 34 cases (97%) of functional adenoma. No imaging recurrences were seen in patients who had nonfunctional adenomas. A total of 57 medial walls were removed in 50 patients. Medial wall invasion was histologically confirmed in 93% of nonfunctional adenomas and 83% of functional adenomas. There were no deaths or internal carotid artery injuries, and the average blood loss was 378 ml. Four patients (8%) developed a new, transient cranial nerve palsy, and 2 of these patients required reoperation for blood clot evacuation and fat graft removal. There were no permanent cranial nerve palsies.

CONCLUSIONS

The medial wall of the CS can be removed safely and effectively, with minimal morbidity and excellent resection and remission rates. Further follow-up is needed to determine the long-term results of this anatomically based technique, which should only be performed by very experienced endonasal skull base teams.
El portavoz del aperturismo moderado: el protagonismo discreto del Ya durante la Transición Española
Authors: Tulloch Christopher D.
Published: September 2018

En este artículo se analiza uno de los aspectos menos estudiados sobre la relación entre la prensa española y la Transición: el papel del diario católico Ya, líder de ventas entre los rotativos madrileños a la hora de producirse el cambio democrático. En el panorama periodístico de la época, Ya ocupa un lugar singular: está desligado de la prensa del Movimiento, no pertenece a la tradición monárquica de ABC ni La Vanguardia y se encuentra a una distancia ideológica notable de la nueva prensa postfranquista representada por El País. A través de un análisis de contenido de más de 600 editoriales de la época, este artículo demuestra cómo este diario conservador navegó entre las aguas turbulentas del momento y cómo se enfrentó al desafío de apostar por la vía reformista, el aperturismo político y las nuevas reglas del juego democrático sin perder el sentido de moderación y la apuesta centrista que le caracterizaba.

Published: September 2018

El impacto de los comentarios en redes sociales con relación a crisis alimentarias es un objeto de estudio reciente, cuyos efectos hay que seguir. En esta investigación se analiza el caso de la carne roja y sus presuntos efectos cancerígenos con el objetivo de determinar el seguimiento en Facebook y Twitter y el carácter de los comentarios (positivos, neutros o negativos). La agencia internacional para la investigación del cáncer (dependiente de la OMS) presentó el 26 de octubre de 2015 un informe donde se evaluaba la carcinogenicidad del consumo de carne incluyéndola en el grupo 2A. Esta noticia estuvo presente en las redes sociales, principalmente en Facebook y Twitter, las más utilizadas en España en ese momento. Por ello, se utiliza la metodología cualitativa de análisis de sentimiento en esas redes sociales y las publicaciones relacionadas con la noticia. Se buscaron las publicaciones del 26 de octubre al 26 de noviembre de 2015 y se utilizaron hashtags específicos (“carne roja” y “OMS”) para centrar la búsqueda. Las publicaciones se clasificaron en positivas, neutras o negativas. También se valoraron las reacciones de los otros usuarios en cada publicación mediante un análisis estadístico cuantitativo. Se analizaron 391 publicaciones en Twitter y 33 en Facebook. En la primera red social, se encontraron publicaciones en todo el periodo de tiempo acotado; en Facebook, solo en la mitad del tiempo. El 57,6% de las publicaciones de Facebook presentan una intencionalidad neutra, el 27,3% negativa y el 15,1% positiva. En Twitter, 47,6% son neutras, 39,6% negativas y 12,8% positivas. El seguimiento de otros usuarios a las publicaciones estudiadas no fue estadísticamente significativo. La apreciación de los usuarios cambia con el paso del tiempo, pasando de comentarios negativos y neutros a neutros y positivos hasta que solo quedaron información objetiva. También se observa una falta de comunicación entre las entidades oficiales y los usuarios de estas redes.

Published: September 2018

Sebagian  wilayah di kota Banjarmasin tergenang air apabila turun hujan dengan curah yang tinggi, itu diakibatkan kurang berfungsinya saluran drainase dan sungai. Dimana banyak saluran-saluran drainase di kota Banjarmasin ini dipenuhi banyak sampah, sedangkan kendala untuk sungai tidak berbeda jauh dengan kendala drainase, banyak dipenuhi sampah serta kondisi eksisting yang tidak sebanding dengan volume air yang ada dan dipengaruhi oleh bangunan-bangunan rumah penduduk yang menjorok ke bibir sungai.

Tujuan dalam penelitian ini adalah untuk menganalisa kondisi eksisting empat sungai di Kecamatan Banjarmasin Tengah yang sudah ada.

Berdasarkan hasil penelitian ke-4 sungai, di dapat Sungai Tatas Qsal(1) 2.931 > Qaliran+hujan(1) 2.816, Sungai Teluk Dalam dengan Qsal(2) 3.082 > Qaliran+hujan(2) 3.027, Sungai Skip Lama dengan Qsal(3) 0.447 >  Qaliran+hujan(3) 0.300, dan Sungai Skip Lama dengan Qsal(4)  0.447 > Qaliran+hujan(4) 0.287. Maka dapat diketahui ke-4 sungai dapat menampung debit yang ada, tetapi masih terjadi potensi peluapan pada waktu pasanga dan hujan, yang diakibatkan oleh adanya penyumbatan oleh sampah dan endapan di beberapa tempat sehingga mempengaruhi pengalirannya, sedangkan pada musim hujan menjadi tempat untuk pembuangan akhir drainase di sekitar sungai tersebut.

An electromagnetic acoustic transducer (EMAT) design using an air-cored solenoid coil as a pulsed electromagnet is proposed for the high-temperature non-contact monitoring of metal processing, and the operation of a prototype device is confirmed at temperatures ranging from room temperature to 700 °C. The coil generates a biasing magnetic field that allows the device to overcome the Curie temperature limitations of conventional EMATs. Pulse-echo measurements on carbon steel are made at high temperatures, and the superposition of the nth compression method is used as a signal processing technique to confirm that the shear wave velocity decreases with increasing temperature, and it is verified that the EMAT can operate at high temperature.

The International Space Station (ISS) has been regarding as a laboratory for experiments in numerous microgravity science discipline. However, the microvibration has a serious impact on science experiments on the ISS as well as existing electromagnetic actuators could not satisfy the requirement of good linearity needed for large stroke of low frequency vibration isolation platforms. This paper aims to design a maglev actuator with good linearity, which could be applied to microgravity vibration isolation platforms. Based on the principle of Lorentz force and self-demagnetization effect, the structural form and preliminary design indices of the actuator were presented. In order to minimize the weight and heat consumption of its coil, parametric design was carried out and multi-objective optimization was adopted for it. Moreover, to investigate the dynamic characteristics of the actuator, system identification was performed to obtain a mathematical model of its control channel, which has good fitting degree of the time and frequency domain signals. Therefore, the result provides an important basis for structural optimal design of the actuator for microgravity vibration isolation system.

Authors: Tang Yan-Ru
Published: September 2018

The optimum conditions of complex color reaction between Mg2+ and arsenazo-III (ASA-III) in the presence of polyvinyl alcohol were studied. In the medium of pH 10.0 ammonia-ammonium chloride, Mg2+ and ASA-III form a 1:2 purple complex and the maximum absorption peak is at 574 nm. At this wavelength, the absorbance (A) is linearly related with the concentration of Mg2+ over the range of 0.1–2.5 μg/mL and its equation: A = 0.4969 C (μg/mL)+0.0634, with a regression coefficient of 0.9993. The apparent molar absorption coefficient of method is 1.35×104 L·mol–1·cm–1 and its detection limit is 76 ng/mL. Appropriate amount of polyvinyl alcohol can make sensitivity of the determination of magnesium increase 10.1%. The method was used to determine magnesium in potato and salt samples. The recovery of the standard addition was 99.6%–100.5%. The relative standard deviation was less than 5% for thirteen replicate determinations. The reliability of this method has been certified by parallel determination against atomic absorption spectrometric method.

Published: September 2018

To study the photosensitivity of furocoumarins to proteins, we choose imperatorin (Imp) and Cysteine (Cys), the most active amino acid in proteins, as the experimental subjects. We used UV light to irradiate Imp, Cys and their mixture separately and dedicated from the MS that Cys was weakly oxidized to Cystine, while strongly oxidized to dithiiodipropionic acid hydrate, di-(α-hydroxy-β-dithio sulfoxide) propionic acid, di-(α-keto-β-thithian sulfone) propionic acid and Cystine sulfone disodium salt. The characteristic absorption wavelength of Imp and the mixture were red shifted from 303 nm to 312 nm. This is due to the leaving of isopentenyl moiety at Imp and the lactone bond cleavage under UV light. HPLC analysis showed that two new substances were generated under UV irradiation, and the retention time was 6.3 and 23.4 min respectively. High-resolution MS analysis showed that UV light firstly induced hydrolysis of the lactone, removal of the isopentenyl group in Imp and deamination, dehydrogenation, oxidation of the Cys, and then Imp and its photochemical products chemically reacted with Cys. The product at 6.3 min was purified by a semi-preparative HPLC and successively analyzed by MS and NMR spectroscopy, identified that it was 8-hydroxypsoralen.

Stunting is caused by three factors, involving individuals’ food intake, birth weight, and health condition; the quality and quantity of food nutrition, human resources, number and family structure, parenting, health care, and services; and environmental factors that include social infrastructure, educational services and health services.This aimed to find the relationship between mothers’ education level and exclusive breastfeeding toward the toddlers’ stunting in South Sulawesi Province 2015 based on the report of secondary data analysis on Nutrition Status (PSG) 2015.This research used 2015 PSG data with observational design. The samples in this research were toddlers in 3 cities or regency in South Sulawesi Province with the highest stunting event rate, they were Jeneponto (300 toddlers), Pangkep (300 toddlers) and Tana Toraja (298 toddlers). Secondary data were taken from PSG report of 2015. The nutrition status was measured by anthropometry. Mothers’ education level and exclusive breastfeeding data were obtained by asking respondents using PSG 2015 questionnaires. To find out the relationship of two variables, it was conducted yate's correlation test using SPSS program. The data were presented in the form of frequency distribution tables and narration.The results showed that the prevalence of stunting was 44%. The proportion of lower educated mothers was 56.5%, while exclusive breastfeeding was quite high at 94.8%. Mothers with less education (27.7%) had stunting children, while 27.3% well-educated mothers have normal children and there was a significant relationship between mother education level and stunting on toddlers (p = 0,001). The stunting was found on toddlers who are not exclusively breastfed (0.9%) and exclusively breastfed (43.1%), and there was a significant relationship between exclusive breastfeeding and stunting incidence in toddlers (p = 0.000).

Published: September 2018

Recently, an increasing number of rare-earth-based equiatomic quaternary compounds have been reported as promising novel spintronic materials. The rare-earth-based equiatomic quaternary compounds can be magnetic semiconductors (MSs), spin-gapless semiconductors (SGSs), and half-metals (HMs). Using first-principle calculations, we investigated the crystal structure, density of states, band structure, and magnetic properties of a new rare-earth-based equiatomic quaternary Heusler (EQH) compound, ScFeRhP. The results demonstrated that ScFeRhP is a HM at its equilibrium lattice constant, with a total magnetic moment per unit cell of 1 μB. Furthermore, upon introduction of a uniform strain, the physical state of this compound changes with the following transitions: non-magnetic-semiconductor-(NMS) → MS → SGS → HM → metal. We believe that these results will inspire further studies on other rare-earth-based EQH compounds for spintronic applications.

Motion Freeze (MF), which integrates 100% of the signal of each respiratory phase in four-dimensional positron emission tomography (4D-PET) images and creates the MF-PET, is capable of eliminate the influences induced by respiratory motion and dispersing from three-dimensional PET (3D-PET) and 4D-PET images. In this study, the effectiveness of respiratory gated radiotherapy applying MF-PET (MF-Plan) in lung cancer patient was investigated and compared with three-dimensional intensity modulated radiotherapy (3D-Plan) and routine respiratory gated radiotherapy (4D-Plan) on the impact of target volume and dosimetry. Thirteen lung cancer patients were enrolled. The internal target volumes were generated with 40% of maximum standardized uptake value. The 3D-Plan, 4D-Plan, and MF-Plan were created for each patient to study the radiation to the targets and organs at risk. MF-Plans were associated with significant reductions in lung, heart, and spinal cord doses. The median reductions in lung V20, lung mean, heart mean doses, and spinal cord maximum dose compared with 3D-Plans were improved. When compared with 4D-Plans, the median reductions in lung V20, lung mean dose, heart mean dose, and spinal cord maximum dose were improved. Our results indicate that the MF-Plan may improve critical organ sparing in the lung, heart, and spinal cord, while maintaining high target coverage.

Governments these days are demanding better Smart City technologies in order to connect with citizens and understand their demands. For such governments, much needed information exists on social media where members belonging to diverse groups share different interests, post statuses, review and comment on various topics. Aspect extraction from this data can provide a thorough understanding of citizens’ behaviors and choices. Also, categorization of these aspects can better summarize societal concerns regarding political, economic, religious and social issues. Aspect category detection (ACD) from people reviews is one of the major tasks of aspect-based sentiment analysis (ABSA). The success of ABSA is mainly defined by the inexpensive and accurate machine-processable representation of the raw input sentences. Previous approaches rely on cumbersome feature extraction procedures from sentences, which adds its own complexity and inaccuracy in performing ACD tasks. In this paper, we propose an inexpensive and simple method to obtain the most suitable representation of a sentence-vector through different algebraic combinations of a sentence’s word vectors, which will act as an input to any machine learning classifier. We have tested our technique on the restaurant review data provided in SemEval-2015 and SemEval-2016. SemEval is a series of global challenges to evaluate the effectiveness of disambiguation of word sense. Our results showed the highest F1-scores of 76.40% in SemEval-2016 Task 5, and 94.99% in SemEval-2015 Task 12.
Foreign Workers and the Wage Distribution: What Does the Influence Function Reveal?
Authors: Choe Chung , Van Kerm Philippe
Published: September 2018

This paper draws upon influence function regression methods to determine where foreign workers stand in the distribution of private sector wages in Luxembourg, and assess whether and how much their wages contribute to wage inequality. This is quantified by measuring the effect that a marginal increase in the proportion of foreign workers—foreign residents or cross-border workers—would have on selected quantiles and measures of inequality. Analysis of the 2006 Structure of Earnings Survey reveals that foreign workers have generally lower wages than natives and therefore tend to haul the overall wage distribution downwards. Yet, their influence on wage inequality reveals small and negative. All impacts are further muted when accounting for human capital and, especially, job characteristics. Not observing any large positive inequality contribution on the Luxembourg labour market is a striking result given the sheer size of the foreign workforce and its polarization at both ends of the skill distribution.
Raising Semantics-Awareness in Geospatial Metadata Management
Authors: Fugazza Cristiano , Pepe Monica , Oggioni Alessandro , Tagliolato Paolo , Carrara Paola
Published: September 2018

Geospatial metadata are often encoded in formats that either are not aimed at efficient retrieval of resources or are plainly outdated. Particularly, the quantum leap represented by the Semantic Web did not induce so far a consistent, interlinked baseline in the geospatial domain. Datasets, scientific literature related to them, and ultimately the researchers behind these products are only loosely connected; the corresponding metadata intelligible only to humans, duplicated in different systems, seldom consistently. We address these issues by relating metadata items to resources that represent keywords, institutes, researchers, toponyms, and virtually any RDF data structure made available over the Web via SPARQL endpoints. Essentially, our methodology fosters delegated metadata management as the entities referred to in metadata are independent, decentralized data structures with their own life cycle. Our example implementation of delegated metadata envisages: (i) editing via customizable web-based forms (including injection of semantic information); (ii) encoding of records in any XML metadata schema; and (iii) translation into RDF. Among the semantics-aware features that this practice enables, we present a worked-out example focusing on automatic update of metadata descriptions. Our approach, demonstrated in the context of INSPIRE metadata (the ISO 19115/19119 profile eliciting integration of European geospatial resources) is also applicable to a broad range of metadata standards, including non-geospatial ones.
