#1
John Hannigan
Despite covering around 70 percent of the earth's surface, the ocean has long been ignored by sociology or treated as merely an extension of land-based systems. Increasingly, however, oceans are assuming a higher profile, emerging both as a new resource frontier, a medium for geopolitical rivalry and conflict, and a unique and threatened ecological hot spot. In this article, I propose a new sociological specialty area, the "sociology of oceans" to be situated at the interface between environmental sociology and traditional maritime studies...

Odorant binding proteins (OBPs) and chemosensory proteins (CSPs) of arthropods are thought to be involved in chemical recognition which regulates pivotal behaviors including host choice, copulation and reproduction. In insects, OBPs and CSPs located mainly in the antenna but they have not been systematically characterized yet in Bemisia tabaci which is a cryptic species complex and could damage more than 600 plant species. In this study, among the 106,893 transcripts in the head assembly, 8 OBPs and 13 CSPs were identified in B...

Online social networks have transformed the way in which humans communicate and interact, leading to a new information ecosystem where people send and receive information through multiple channels, including traditional communication media. Despite many attempts to characterize the structure and dynamics of these techno-social systems, little is known about fundamental aspects such as how collective attention arises and what determines the information life-cycle. Current approaches to these problems either focus on human temporal dynamics or on semiotic dynamics...

Cytochrome b (Cytb, EC 1.10. 2.2) is the only cytochrome coded by mitochondrial DNA and involved in electron transport in the mitochondrial respiratory chain. In this study, characterization of cytb protein was identified on fifty-four insect protein sequences, from different orders. According to the conserved motifs obtained with MEME and MAST tools, eight motifs were common to all insects. The structural and functional analyses of 16 selected insects from different orders were performed with ProtParam, Compute PI, SOPMA, SignalP 4...

The genome annotation and identification of gene function depends on conserved biochemical activity. However, in the cell, proteins with the same biochemical function can participate in different cellular pathways and cannot complement one another. Similarly, two proteins of very different biochemical functions are put in the same class of cellular function; for example, the classification of a gene as an oncogene or a tumour suppressor gene is not related to its biochemical function, but is related to its cellular function...

Data from approximately 140 articles and reports published since 2000 on drinking, alcohol use disorder (AUD), correlates of drinking and AUD, and treatment needs, access, and utilization were critically examined and summarized. Epidemiological evidence demonstrates alcohol-related disparities across U.S. racial/ethnic groups. American Indians/Alaska Natives generally drink more and are disproportionately affected by alcohol problems, having some of the highest rates for AUD. In contrast, Asian Americans are less affected...

Peroxidases (PRXs) are widely existed in various organisms and could be divided into different types according to their structures and functions. Specifically, the Class III Peroxidase, a plant-specific multi-gene family, involves in many physiological processes, such as the metabolism of auxin, the extension and thickening of cell wall, as well as the formation of lignin. By searching the pear genome database, 94 non-redundant PRXs from Pyrus bretschneideri (PbPRXs) were identified. Subsequently, analysis of phylogenetic relationships, gene structures, conserved motifs, and microsynteny was performed...

BACKGROUND: A physician is frequently unable to distinguish bacterial from viral infections. ImmunoXpert is a novel assay combining three proteins: tumour necrosis factor-related apoptosis-inducing ligand (TRAIL), interferon gamma induced protein-10 (IP-10), and C-reactive protein (CRP). We aimed to externally validate the diagnostic accuracy of this assay in differentiating between bacterial and viral infections and to compare this test with commonly used biomarkers. METHODS: In this prospective, double-blind, international, multicentre study, we recruited children aged 2-60 months with lower respiratory tract infection or clinical presentation of fever without source at four hospitals in the Netherlands and two hospitals in Israel...

Physicochemical processes that take place at the oil-water interface of an epoxy-amine emulsion polymerisation system influence the properties and structural morphology of the polymeric microparticles formed. Investigating these processes, such as the transport of monomers across the liquid/liquid interface brings new understanding which can be used to tune polymeric morphology. Two different approaches are used to provide new insights on these processes. Microelectrochemical measurements at expanding droplets (MEMED) is used to measure the transfer of amine from an organic phase comprised of epoxide and amine into an aqueous receptor phase...

Is cultural evolution needed to explain altruistic selfsacrifice? Some contend that cultural traits (e.g. beliefs, behaviors, and for some "memes") replicate according to selection processes that have "floated free" from biology. One test case is the example of suicide kamikaze attacks in wartime Japan. Standard biological mechanisms-such as reciprocal altruism and kin selection-might not seem to apply here: The suicide pilots did not act on the expectation that others would reciprocate, and they were supposedly sacrificing themselves for country and emperor, not close relatives...

This paper investigates wealth disparities among first-generation immigrants using data from the 2012 Survey of Financial Security. We apply logistic and linear regression models to estimate disparities in homeownership and household equivalent net worth by immigrant status, region of origin, and time since arrival. By focusing on immigrant families from different regions who entered Canada at different points in time, this research applies theories related to assimilation, human capital, and structural barriers to wealth...

In much of the academic debate on the integration of Muslims into Western liberal democracies, Islam is often treated as one or the sole independent variable in the lives of Muslims. Offering to view Islam-or the understanding of Islam among Muslims-as the dependent variable, The Muslim Question in Canada discusses the influence of socioeconomic forces in shaping the Muslim immigrants' opinions, modes of thinking, and even interpretations of their faith. Drawing on this general approach, which is introduced and developed in the book using a variety of both quantitative and qualitative data, this article focuses on a school of thought within the Islamic jurisprudence known as fiqh al-aqalliyyat al-Muslema (the jurisprudence of Muslim minorities)...

Emre Sefer, Carl Kingsford
Diffusion through graphs can be used to model many real-world processes, such as the spread of diseases, social network memes, computer viruses, or water contaminants. Often, a real-world diffusion cannot be directly observed while it is occurring - perhaps it is not noticed until some time has passed, continuous monitoring is too costly, or privacy concerns limit data access. This leads to the need to reconstruct how the present state of the diffusion came to be from partial diffusion data. Here, we tackle the problem of reconstructing a diffusion history from one or more snapshots of the diffusion state...

Carotenoid cleavage oxygenases (CCOs) are a family of dioxygenases, which specifically catalyze the cleavage of conjugated double bonds in carotenoids and apocarotenoids in plants. In this study, genome-wide analysis of CCO genes in pepper plants was performed using bioinformatic methods. At least 11 members of the CCO gene family were identified in the pepper genome. Phylogenetic analysis showed that pepper and tomato CCO genes could be divided into two groups (CCDs and NCEDs). The CCD group included five sub-groups (CCD1, CCD4, CCD7, CCD8, and CCD-like)...

Richard Potvin
La chirurgie de la cataracte a toujours consisté à extraire le cristallin opacifié de l'œil pour le remplacer par une lentille artificielle. Cette intervention rend la vision du patient plus nette, sans pour autant corriger l'erreur de réfraction, c'est-à-dire la nécessité de porter des lunettes ou des lentilles cornéennes après l'opération. Les instruments diagnostiques et chirurgicaux modernes permettent désormais de corriger ces erreurs de réfraction au moment de l'opération, ce qui a fait émerger une nouvelle notion, celle de la chirurgie réfractive de la cataracte...

Starting as an Internet meme, the homosexually themed gao-ji discourse recently became popular among Chinese urban youth in describing intimate relationships among heterosexual men. Positioned within a body of scholarship on the interplay between language, homophobia, and the construction of heteromasculinity, this article suggests that the gao-ji discourse manifests a form of male homosociality, through which new boundaries of Chinese heteromasculinity may be renegotiated. Based on qualitative interviews with college students, the article first tracks the genealogy of the gao-ji discourse in the wake of China's booming Internet culture...
