If everything is syntax, why are words so important? An a-morphous but non-lexicalist approach
Authors: Mendívil-Giró José-Luis 
Published: July 2019

AbstractThis paper presents the hypothesis that words (and not morphemes) are the minimal units of connection between sound and meaning in human languages. Such a proposal implies the definition of the word as a categorized syntactic derivation that is linked in memory to a representation in the sensorimotor system. The main implications of the hypothesis are the following: (i) A non-lexicalist model is compatible with the phenomena of lexical integrity and lack of productivity that motivate lexicalist models. (ii) It can be concluded that bound morphemes (roots and affixes) are neither syntactic nor conceptual entities, but purely morphophonological ones. Morphemes are side effects of linguistic change operating as resources to optimize the processing and memorization of words. And (iii) a neo-constructionist conception of words is made compatible with a paradigmatic morphology.
Acid-mediated N-iodosuccinimide-based thioglycoside activation for the automated solution-phase synthesis of α-1,2-linked-rhamnopyranosides
Authors: Kohout Victoria R. , Pirinelli Alyssa L. , Pohl Nicola L. B. 
Published: July 2019

Abstract

Carbohydrate structures are often complex. Unfortunately, synthesis of the range of sugar combinations precludes the use of a single coupling protocol or set of reagents. Adapting known, reliable bench-chemistry reactions to work via automation will help forward the goal of synthesizing a broad range of glycans. Herein, the preparation of di- and tri-saccharides of alpha 1→2 rhamnan fragments is demonstrated using thioglycoside donors with the development for a solution-phase-based automation platform of commonly used activation conditions using N-iodosuccinimide (NIS) with trimethylsilyl triflate. Byproducts of the glycosylation reaction are shown to be compatible with hydrazine-based deprotection conditions, lending broader functionality to this method as only one fluorous-solid-phase extraction step per coupling/deprotection cycle is required.
Retreatment of a Print Damaged by Excessive Sodium Borohydride Bleaching
Authors: Müller Emily M. K. , Henniges Ute , Brückle Irene 
Published: July 2019

Abstract
An etching that was visibly damaged as a result of previous bleaching with a 5.6 % aqueous sodium borohydride solution underwent retreatment involving washing to stabilize the embrittled paper and to remove potentially present bleaching residues. During a final immersion in a dilute calcium hydrogen carbonate solution administered for deacidification, an unexpected and severe blistering occurred that is explained as a recurrence of previous bleaching-related blistering. The blisters were laid down. The treatment concluded with a consolidation of the bleach-damaged paper surface using a 0.5 % gelatine solution applied by misting.
A status review of terpenes and their separation methods
Authors: Ben Salha Ghada , Abderrabba Manef , Labidi Jalel 
Published: July 2019

Abstract
Terpenes or terpenoids are extracted or steam distilled for the recovery of the essential oils of specific fragrant plants. These steam distillates are used to create fine perfumes, to refine the flavor and the aroma of food and drinks, and to produce medicines from plants (phytopharmaca). In recent years, consumers have developed an increasing interest in natural products, as most of these terpenoids have been identified as high value chemicals in food, cosmetic, pharmaceutical, biotechnology, and industrial crops. Extensive chemical techniques and biological tests have led to the identification, biological characterization, and extraction of major components that are of wide interest, especially to the cosmetic and industrial recovery of selective terpenes. The current status of the knowledge of their general structure, functions, and bioactive properties and the methods for their separation are covered in this review.
The Connection between the Averted Infections Ratio and the Rate Ratio in Active-control Trials of Pre-exposure Prophylaxis Agents
Authors: Dunn David T. , Glidden David V. 
Published: July 2019

Abstract
The design and analysis of active-control trials to evaluate experimental HIV pre-exposure prophylaxis (PrEP) agents pose serious statistical challenges. We recently proposed a new outcome measure, the averted infections ratio (AIR) – the proportion of infections that would be averted by using the experimental agent rather than the control agent (compared to no intervention). The main aim of the current paper is to examine the mathematical connection between AIR and the HIV incidence rate ratio, the standard outcome measure. We also consider the sample size implications of the choice of primary outcome measure and explore the connection between effectiveness and efficacy under a simplified model of adherence.
Existential and locative constructions in Mandarin Chinese

AbstractDespite previous studies (cf. among others Huang 1987. Existential sentences in Chinese and (in)definiteness. In Eric J. Reuland & Alice G.B. Ter Meulen (eds.),The representation of (In)definiteness, 226–253. Cambridge, Mass.: MIT Press; Li, Yen-Hui Audrey. 1990.Order and constituency in Mandarin Chinese. Dordrecht: Kluwer; Li, Yen-Hui Audrey. 1998. Two types of existential sentences.Illinois Papers in Linguistics26. 175–191; Pan, Haihua. 1996. Imperfective aspectzhe, agent deletion, and locative inversion in Mandarin Chinese.Natural Language and Linguistic Theory14(2). 409–432), the defining characteristics of existential sentences in Chinese (including potential equivalents oflocative inversionin English) have remained controversial. This is shown to be due to the failure to acknowledge the existence of two different constructions, theexistential construction(ExC) ‘Ø V DP’ where a sentence-initial phrase indicating location (PlaceP) is not required, on the one hand, and thelocative construction(LoC) with an obligatory PlaceP, on the other: ‘PlaceP V DP’. Only the ExC can serve as a diagnostic context for unaccusative verbs, whereas the LoC allows for a wide range of verbs, including a subset of unergative verbs. Furthermore, two types of LoC need to be distinguished, depending on the type of aspect (perfective aspect -levs imperfective aspect-zhe), giving rise to different semantics. Both have, however, in common that the PlaceP occupies the subject position (SpecTP), not the topic position, and that it is merged in SpecTP, not moved there, as evidenced by the systematic lack of a corresponding source structure with the PlaceP in postverbal position.
An interface analysis of marked copular constructions: The case of there-sentences
Authors: Ramaglia Francesca 
Published: July 2019

AbstractThis paper proposes an interface account of existential sentences, in which the examination of the semantic, morphosyntactic, discourse and prosodic properties of these and related constructions is aimed to explore the similarities and differences with other types of IS-marked copular structures. In particular, a structural parallelism is proposed between existentials and clefts, as well as between (inverted) locatives and (inverted) pseudoclefts. In the analysis of existential constructions, the investigation of the Definiteness Effect reveals the need for a distinction acrossthere-sentences; in particular, the interface properties of the relevant structures suggest that different analyses should be provided for existential and presentationalthere-sentences, which present crucial formal asymmetries at various levels of analysis.
Interaction of a Spreading Mantle Plume Head and the Ancient Lithosphere: Studying Mantle Xenoliths in Basalts and Lamprophyre Diatremes of Western Syria
Authors: Sharkov E.V. , Bogatikov O.A. 
Published: July 2019

Abstract
—Our study of mantle xenoliths in the Cretaceous lamprophyre diatremes and late Cenozoic plateau basalts of western Syria has shown that the ancient lower crust that existed in the Cretaceous and was composed of garnet granulites and eclogite-like rocks was replaced by mantle peridotites in the late Cenozoic. We conclude that the heads of the local (secondary) plumes of the present-day Afro-Arabian thermochemical mantle plume responsible for the regional basaltic magmatism reached the basement of the ancient upper sialic crust, where they spread, leading to a displacement of the mafic lower crust.
Seismic-Moment Tensor of Earthquakes in Azerbaijan for 2012–2015
Authors: Yetirmishli G.J. , Kazimova S.E. , Kazimov I.E. 
Published: July 2019

Abstract
—Seismic-moment tensor solutions for earthquakes in Azerbaijan for 2012–2015 have been calculated with a new method by full waveform inversion of broadband data from modern digital seismic stations and processed statistically. The results are used to model main faulting elements in the region, to correlate the seismicity and fault patterns, and to compile a map of fault plane orientations for large events. The principal compression stress (P) directions are NW to SE in the Zaqatala area and N–S in the Sheki area but then gradually change clockwise toward NE–SW in the Caspian Sea. The directions of principal extension are mainly NE–SW and N–S within the zone where the Kura basin is subsiding beneath the Great Caucasus.
Ground-Penetrating Radar for Studies of Peatlands in Permafrost

Published: July 2019

Abstract
—Ground-penetrating radar (GPR) profiling is applicable to study peatlands and swampy areas in permafrost but have some limitations in summer time. Theoretical calculations and field experiments show that estimating attenuation of electromagnetic waves is required for planning GPR survey. GPR data acquired with a 300 MHz antenna fail to resolve reflections from below the permafrost if the thaw/permafrost boundary is deeper than 1.5 m and the attenuation coefficient is 0.7, as in water-saturated peat. GPR data allow high-resolution lithological division of permafrost and provide reliable constraints on the depths to interfaces and physical properties of the ground. Thus, GPR can fully or partly substitute for the time- and labor-consuming direct measurements. The inferences have been confirmed by field results.
A Comparative Analysis of Catholic Educational Concepts: the Case of Jesuit and Fr. Luigi Giussani’s Concepts
Authors: Labokas Juozapas 
Published: July 2019

Currently, value-based education occupies a leading position within the contemporary academic discourse on education. Catholic education holds a decent share in this overall discussion. This is partly due to the growing number of Catholics in Africa and Asia as well as globalization and secularization processes. Considering this fact, the philosophical underpinnings of Catholic education, its identity issues, and future perspectives are gaining more and more attention from the academic audience worldwide. In this study, an attempt was made to examine and compare two different concepts of Catholic education, one of Italian Catholic priest Fr. Luigi Giussani and that of the Jesuits. The research was aimed at analyzing and evaluating the similarities and differences of these concepts, revealing their interrelation. The analysis showed that these educational concepts have only slightly different goals and use different wording to define their aims. This situation is preconditioned by different historical-cultural contexts and experiences. In conclusion, Jesuit education tends to stress academic achievements and a value-based education approach, while Giussani’s concept emphasizes an interest in showing the importance and meaning of human reality and value education through its verification according to real-life needs. This allows to categorize Jesuit education as more traditionally-Catholic oriented while viewing Giussani’s concept as more suitable for Western secularized societies, which are not or less familiar with such notions as fate, religion, Christianity, God, etc. Despite the fact that these concepts employ different educational methods and approaches and have only slightly different goals, their interrelationship can be described as complementary rather than differentiated or competing.

OBJECTIVES:
We examined demographic characteristics and birth outcomes of infants with neonatal abstinence syndrome (NAS) and their mothers in Canada.

METHODS:
This retrospective, population-based, descriptive cross-sectional study of mother-infant dyads included all singleton live births in Canada (excluding Quebec), from 2005–2006 to 2015–2016 (N = 2 881 789). Demographic characteristics, NAS, and neonatal and maternal morbidities were identified from delivery hospitalization data (including diagnostic codes). The main composite outcomes were maternal and neonatal mortality and/or severe morbidity, including death and potentially life-threatening conditions in the mother and the infant, respectively. Logistic regression yielded adjusted odds ratios (aORs) and 95% confidence intervals (CIs).

RESULTS:
The study included 10 027 mother-infant dyads with NAS. The incidence of NAS increased from 0.20% to 0.51%. Maternal mortality was 1.99 vs 0.31 per 10 000 women in the NAS group versus the comparison group (aOR = 6.53; 95% CI: 1.59 to 26.74), and maternal mortality and/or severe morbidity rates were 3.10% vs 1.35% (aOR = 2.21; 95% CI: 1.97 to 2.49). Neonatal mortality was 0.12% vs 0.19% (aOR = 0.28; 95% CI: 0.15 to 0.53), and neonatal mortality and/or severe morbidity rates were 6.36% vs 1.73% (aOR = 2.27; 95% CI: 2.06 to 2.50) among infants with NAS versus without NAS.

CONCLUSIONS:
NAS incidence increased notably in Canada between 2005–2006 and 2015–2016. Infants with NAS had elevated severe morbidity, and their mothers had elevated mortality and severe morbidity. These results highlight the importance of implementing integrated care services to support the mother-infant dyad during childbirth and in the postpartum period.

Objetivo: determinar a sobrecarga do cuidado e sua associação com a rede de apoio social e estresse emocional do cuidador principal do idoso atendido no serviço de atenção domiciliar.Metodologia: estudo quantitativo e analítico realizado com 94 idosos e seus respectivos cuidadores. Quanto à coleta de dados, para o idoso foram utilizados os instrumentos deperfil sociodemográfico e morbidades, Mini Exame do Estado Mental, índice de Katz, escala de Lawton e Brody; e para o cuidador, o instrumento de perfil sociodemográfico, escala de sobrecarga de Zarit, Self-Reporting Questionnaire e instrumento de medida da rede e apoio social.Resultados: verificou-se predomínio de idosos do sexo feminino, idade superior a 80 anos, casados e com escolaridade de 1 a 4 anos. Os cuidadores principais são do sexo feminino,menores de 60 anos, casados, escolaridade de 9 a 12 anos; a maioria era filha do idoso e viviam com ele. Observouse uma associação entre a sobrecarga do cuidador e a dependência do idoso para as atividades instrumentais da vida diária, o estresse emocional e o domínio “interação social”.Conclusão: cuidar de idosos pode gerar sobrecarga quando o cuidador principal está sob estresse, não possui uma rede social de apoio e o idoso é dependente, portanto, o profissionalprecisa traçar um plano de cuidados para o binômio idoso-família.

Published: July 2019

Salah satu dari ketentuan hukum jinayah dalam hukum Islam adalah bahwa siapapun yang mencuri harta orang lain maka pelakunya diberi sanksi hukuman yaitu hukuman had potong tangan seperti yang dijelaskan dalam ayat 38 dari surat al-Maidah di atas. Kemudian yang pelaksanaannya dijelaskan dalam hadits-hadits Rasul Saw. Dengan demikian penetapan had potong tangan bagi pencuri tujuannya adalah untuk memberikan jaminan kemaslahatan terhadap harta manusia dari kerusakan, kehancuran dan dari kepemilikan yang tidak dibenarkan Islam dari pihak lain
MANGALEHEN TUOR: Fenomena Living Hadis dalam Adat Mandailing
Authors: Khairani Lanna 
Published: July 2019

Tuor merupakan sebutan mahar pernikahan dikalangan masyarakat Mandailing dan Angkola, dimana seorang laki-laki wajib memberikan tuor kepada calon perempuan yang akan dinikahi. Namun sebagian orang, yakni pemuda yang akan menikah tuor bisa menjadi penghalang dikarenakan ketiadaan atau ketidak sanggupan untuk memenuhi permintaan keluarga perempuan karena ekonomi laki-laki yang rendah. Di adat Mandailing tuor bisa tinggi dikarenakan dilihat dari segi status perempuan yaitu pendidikannya, keturunannya dan lain sebagainya. Tujuan dari penelitian ini adalah pertama, mengetahui pelaksanaan pemberian tuor, Kedua untuk mengetahui pandangan masyarakat tentang tradisi pemberian tuor. Ketiga untuk mengetahui nilai hadis yang terkandung dalam tradisi tuor dalam adat Mandailing. Jenis penelitian lapangan (field research) yang bersifat deskriptif kualitatif, sedangkan teknik pengumpulan data dilakukan dengan cara observasi, wawancara dan dokumentasi. Penelitian ini dapat disimpulkan: pertama, dalam hal sejarah, tuor telah ada sejak masa raja-raja Mandailing. Kedua, dalam pelaksanaan tuor dimulai sebelum hari H pernikahan, Ketiga,landasan masyarakat Mandailing dalam memberikan tuor, mereka berdalil kepada hadis-hadis tentang mahar. Dampak negatif tradisi tuor dalam adat Mandailing, dapat membatalkan pernikahan, pernikahan tertunda, Walimatul ’ursy hanya dilaksanakan satu pihak, nikah lari, dapat memberatkan seorang laki-laki untuk menikah. Sedangkan segi positifnya ialah untuk menghindari terjadinya perceraian, adanya tanggung jawab orang tua terhadap anak-anaknya,dan lain sebagainya.
