AbstractFine particulate matter (PM2.5) mainly originates from combustion emissions. On-road transportation is considered one of the primary sources of PM2.5 emission. The relationship between on-road transportation and PM2.5 concentration varies temporally and spatially, and the estimation for this variation is important for policymaking. Here, we reveal the quantitative association of PM2.5 concentration with on-road transportation by the spatial panel Durbin model and the geographical and temporal weighted regression. We find that 6.17 billion kilometres (km) per km2 on-road transportation increase is associated with a 1-μg/m3 county-level PM2.5 concentration increase in the contiguous United States. On-road transportation marginally contributes to PM2.5, only 1.09% on average. Approximately 3605 premature deaths are attributed to PM2.5 from on-road transportation in 2010, and about a total of 50,223 premature deaths ascribe to PM2.5 taking 6.49% from 2003 to 2016. Our findings shed light on the necessity of the county-level policies considering the temporal and spatial variability of the relationship to further mitigate PM2.5 from on-road transportation.

This book aims to shed light on core questions relating to language and society, language and conflict, and language and politics, in relation to a changing Middle East. While the book focuses on Arabic, it goes way beyond a purely linguistic analysis by bringing to the fore a set of pressing questions about the relationship between Arabic and society. For example, it touches on the development of language policy via an examination of administrative mandates (top-down) in contrast to grassroots initiatives (bottom-up); the deeper layers of the linguistic landscape that highlight the connection between politics, conflict, identity, road signs and street names; Arabic studies and Arabic identity and the myriad ways countries deal simultaneously with globalisation while also seeking to strengthen local and national identity, and more.

ResumenEn este trabajo analizamos las relaciones entre tomas de tierras y Estado, en elAlto Valle de Río Negro en Argentina. En un contexto general de especulacióninmobiliaria, por la que se encarecen los precios de alquileres y terrenos, y depolíticas de vivienda selectivas y acotadas, los sectores populares acceden aun espacio en la ciudad mediante tomas de tierras. Frente a estos conflictos,el Estado, en sus diferentes niveles y poderes, despliega una forma deintervención basada en la criminalización de las luchas por tierra y vivienda.Al mismo tiempo, el poder ejecutivo nacional crea la Secretaría de Acceso alHábitat, para posibilitar la intervención política orientada a la regularizaciónde los asentamientos. Sin embargo, esta intervención tiende a reinscribir laproblemática habitacional en el campo político, para reducirla a un conflicto“entre partes”, eludiendo la responsabilidad estatal.Desde un enfoque metodológico cualitativo, seleccionamos como referenteempírico el caso del asentamiento de Villa Obrera en Fiske, Menuco (Gral.Roca), y las técnicas de recolección de datos se basan en fuentes secundarias,como expedientes judiciales y normativa, y en fuentes primarias como son losrelatos de los protagonistas mediante entrevistas individuales y colectivas.Palabras clave: tomas de tierras, Estado, criminalización de los conflictos.Conflicts caused by land occupation and modesof State intervention: analysis of an experience ofAlto Valle in Río Negro (Argentina)AbstractThis paper analyzes the relationship between State and land occupation,at Alto Valle in Río Negro, Argentina. In a general context of real estatespeculation, where rents and land prices are expensive, and a policy ofselective and limited housing, popular sectors can have access to a spacein the city through land occupation. In front of these conflicts, the Statein its different levels and powers, displays a form of intervention basedon the criminalization of struggles for land and housing. At the sametime, the national executive creates the Secretariat of Access to Habitat,oriented to allow political intervention for the regularization of settlements.However, this intervention tends to re-register the housing problems in thepolitical arena, reducing it to a conflict “between parties” and eluding theresponsibility of the State.From a qualitative methodological approach, we selected as empirical referencethe case of the settlement of Villa Obrera in Fiske, Menuco (GeneralRoca). The techniques of data collection are based on secondary sources, suchas policy and legal records, and primary sources as the stories of protagoniststhrough individual and collective interviews.Keywords: land occupation, State, criminalization of conflicts.Conflitos sobre ocupações de terras e modos deintervenção do estado: análise de uma experiênciado Alto Valle do Rio Preto (Argentina)ResumoEste trabalho analisa as relações entre a posse de terra e o Estado, no AltoValle do Rio Preto, na Argentina.

Information sharing is a ubiquitous social behavior. What causes people to share? Mentalizing, or considering the mental states of other people, has been theorized to play a central role in information sharing, with higher activity in the brain’s mentalizing system associated with increased likelihood to share information. In line with this theory, we present novel evidence that mentalizing causally increases information sharing. In three pre-registered studies (n = 400, 840, and 3500 participants), participants who were instructed to consider the mental states of potential information receivers indicated higher likelihood to share health news compared to a control condition where they were asked to reflect on the content of the article. Certain kinds of mentalizing were particularly effective; in particular, considering receivers’ emotional and positive mental states, led to the greatest increase in likelihood to share. The relationship between mentalizing and sharing was mediated by feelings of closeness with potential receivers. Mentalizing increased feelings of connectedness to potential receivers, and in turn, increased likelihood of information sharing. Considering receivers’ emotional, positive, and inward-focused mental states was most effective at driving participants to feel closer with potential receivers and increase sharing. Data provide evidence for a causal relationship between mentalizing and information sharing and provide insight about the mechanism linking mentalizing and sharing. Taken together, these results advance theories of information sharing and shed light on previously observed brain-behavior relationships.

الملخّص يتناول البحث علاقة الفطرة بالشريعة في التفكير الإسلامي، وما تطرحه هذه العلاقة سواء على مستوى بيان الجوانب المتعلقة بخَلْق الإنسان وما فُطِر عليه ابتداء، وهذا البعد يمثّل الجانب التكوني في مفهوم الفطرة، أو على المستوى المتعلق بالشريعة وفطريتها، أي أنها جارية وفق ما يدركه العقل وتشهد به الفطرة، وهذا البعد يمثّل الجانب التشريعي الذي يطرحه مفهوم الفطرة. لقد زخرت أغلب الكتابات بتناول جانبا واحدا مما يتيحه أو يعكسه مفهوم الفطرة، لكن البحث في العلاقة التناسبية بين الفطرة والشريعة، وما يتيحه هذا النظر المتلازم بين المفهومين على مستوى الإمكانات المتعلقة بقدرات الإنسان الفطرية في فهم وتعقّل الخطاب الشرعي والأحكام التكليفية، والوقوف على غاياته ومقاصده، يبقى في حاجة إلى البحث والاستقصاء. ولذلك تأتي هذه الدراسة لتسليط الضوء على الجانب التشريعي والتكويني في علاقة الشريعة بالفطرة، باعتبارهما نظامين متلازمين يتيحان فهم طبيعة الشريعة وأحكامها ومقاصدها من جهة، وتحديد جوهر وماهية الإنسان الفطرية وإمكاناته في تعقّل هذه الشريعة من جهة ثانية.                  الكلمات المفتاحية: الفطرة، الشريعة، الدين، التكاليف، العقل. Abstract This research addresses the relationship between premordial human nature (fitrah) and Islamic law (SharÊÑah) within the frame of Islamic thought, while exploring the questions it raises at two levels. The first level explains the aspects related to the creation of man and what has initially been bestowed upon him, which represents the evolutionary aspect of the concept of fiÏrah. The second level is related to SharÊÑah and its nature, which evolves according to what is percieved by reason and witnessed by fiÏrah; this represents the legislative aspect presented by the concept of fiÏrah. The majority of studies to date address a single aspect of the illustrations of the concept of fiÏrah. However, research on the dialectic relationship between fiÏrah and SharÊÑah and what its relevant concurrent view provides at the level of potentials related to human innate capacities in understanding and realizing SharÊÑah discourse and mandatory provisions as well as understanding its objectives  remains scarce and requires further research and investigation. Therefore, this study intends to shed light on the legislative and evolutionary aspects of the relationship between SharÊÑah and fiÏrah as two interconnected systems that allow for the understanding of the nature of SharÊÑah, its provisions and purposes, as well as identifying the essence of human innate nature and its potential in perceiving SharÊÑah. Keywords: human nature (fiÏrah), Islamic law (SharÊÑah), religious mandates (TakÉlif), religion, intellect (ÑAqal).

A number of clinical studies have revealed that there is an association between major depression (MD) and gastroesophageal reflux disease (GERD). Both the diseases are shown to affect a large proportion of the global population. More advanced studies for understanding the comorbidity mechanism of these two diseases can shed light on developing new therapies of both diseases. To the best of our knowledge, there has not been any research work in the literature investigating the relationship between MD and GERD using their miRNA biomarkers. We adopt a phylogenetic analysis to analyze their miRNA biomarkers. From our analyzed results, the association between these two diseases can be explored through miRNA phylogeny. In addition to evidence from the phylogenetic analysis, we also demonstrate epidemiological evidence for the relationship between MD and GERD based on Taiwan biobank data.

Lactate is a product of anaerobic glycolysis, used in animal research as an indicator of muscle fatigue. Therefore, it has been used as an indicator of cattle response to long distance transportation. The aim of this study was to assess the relationship of L-lactate concentrations measured using a Lactate Scout+ analyzer and a traditional lactate assay colorimetric kit. Blood samples were collected by venipuncture from 96 steers (Black or Red Angus × Hereford/Simmental and Black or Red Angus × Charolais; 247 ± 38.2 kg BW) prior to loading (LO1) and after 36 h of transport, and prior to reloading and after an additional 4 h of road transportation, and on d 1, 2, 3, 5, 14, and 28 after transport. The Lactate Scout+ analyzer strip was dipped in blood at the time of sampling, while blood samples were collected into sodium fluoride tubes for use in the colorimetric analysis. Pearson correlations were calculated to assess the strength of the relationship between the experimental methods for the quantification of L-lactate concentrations. The magnitude and direction of the correlation, and the level of statistical significance varied over the observed time points, ranging from r = −0.03 (p = 0.75; LO1) to r = 0.75 (p < 0.0001; d 3). The correlation for the pooled data was weak but statistically significant (r = 0.33, p < 0.0001). Based on the low magnitude of the correlation due to variability across sampling time points in this study, the Lactate Scout+ analyzer is not a suitable alternative to a lab-based assay (considered the gold standard) for measuring L-lactate in transported cattle.

Abstract Blood metabolites are used to assess a variety of animal conditions for veterinary diagnosis and research. Concentration of metabolites in blood can be measured using a commercially-available lab-based assay or in real-time using a handheld device developed to be more time- and cost-effective than the lab-based method. Lactate is a product of anaerobic glycolysis, used in animal research as an indicator of muscle fatigue. Therefore, it has been used as an indicator of cattle response to long distance transportation. The aim of this study was to assess the relationship of L-lactate concentrations measured using a Lactate Scout+ analyzer (Lactate Scout, EFK Diagnostics, Barleben, Germany) and a lactate assay colorimetric kit (Lactate Assay Kit, Cell Biolabs Inc., San Diego, CA). Blood samples were collected by venipuncture from 96 steers (245 ± 35.7 kg BW) prior to (L1) and after 36 h, and prior to and after an additional 4 h of road transportation, and on d 1, 2, 3, 5, 14, and 28 after transport. The Lactate Scout+ analyzer strip was dipped in blood at the time of sampling, while blood samples were collected into sodium fluoride tubes for use in colorimetric analysis. Pearson correlations were calculated to determine the relationship between the experimental methods for the quantification of L-lactate concentrations. The strengths and levels of statistical significance of the correlation varied over the observed time points, r = -0.03, P = 0.75 (L1) to r = 0.75, P = &lt; 0.0001 (d 3). The correlation for the pooled data was weak but statistically significant (r = 0.33, P &lt; 0.001). Based on the experimental results, the Lactate Scout+ analyzer is not a suitable alternative to a lab-based assay for measuring L-lactate in transported cattle, due to variability across sampling time points and weak correlation with the traditional enzymatic method.

Abstract Four chronicles written by Alberto Blest Gana between April and May 1862 in the newspaper La voz de Chile, months before the publication of his novel Mariluán, shed light on the close relationship between his production as chronicler and writer. Among the various faits divers discussed in the columns, the issue of a Mapuche delegation’s arrival in Santiago to hold a parlamento with the government about border disputes arises. The oscillating attitude of the chronicler in the face of otherness and his prejudiced comments, which are at the same time full of doubts and perplexities, serve as an incentive for his composing a utopian fiction. This article aims to examine the connections in the relationship between Blest Gana chronicler and novelist to expand the reading possibilities of Mariluán.

Object The authors explored the relationship among the duration of external ventricular drainage, revision of external ventricular drains (EVDs), and cerebrospinal fluid (CSF) infection to shed light on the practice of electively revising these drains. Methods In a retrospective study of 199 patients with 269 EVDs in the intensive care unit at a major trauma center in Australasia, the authors found 21 CSF infections. Acinetobacter accounted for 10 (48%) of these infections. Whereas the duration of drainage was not an independent predictor of infection, multiple insertions of EVDs was a significant risk factor. Second and third EVDs in previously uninfected patients were more likely to become infected than first EVDs. An EVD infection was initially identified a mean of 5.5 ±0.7 days postinsertion (standard error of the mean); these data—that is, the number of days—were normally distributed. Conclusions This pattern of infection is best explained by EVD-associated CSF infections being acquired by the introduction of bacteria on insertion of the drain rather than by subsequent retrograde colonization. Elective EVD revision would be expected to increase infection rates in light of these results, and thus the practice has been abandoned by the authors' institution.

Programmed cell death or type I apoptosis has been extensively studied and its contribution to the pathogenesis of disease is well established. However, autophagy functions together with apoptosis to determine the overall fate of the cell. The cross talk between this active self-destruction process and apoptosis is quite complex and contradictory as well, but it is unquestionably decisive for cell survival or cell death. Autophagy can promote tumor suppression but also tumor growth by inducing cancer-cell development and proliferation. In this review, we will discuss how autophagy reprograms tumor cells in the context of tumor hypoxic stress. We will illustrate how autophagy acts as both a suppressor and a driver of tumorigenesis through tuning survival in a context dependent manner. We also shed light on the relationship between autophagy and immune response in this complex regulation. A better understanding of the autophagy mechanisms and pathways will undoubtedly ameliorate the design of therapeutics aimed at targeting autophagy for future cancer immunotherapies.
