Application of multifractal analysis to segmentation of water bodies in optical satellite images
Authors: San Martin Victor Manuel , Figliola Alejandra 
Published: November 2017

In this paper we study the characteristics of multifractal spectra obtained for remote sensing images through the coarse theory and proposed a method for segmentation of water bodies based on it.In first place, spectra of self-similar images created with Iterated Function Systems are calculated and compared with their statistical spectra. Then, optical remote sensing images are studied, emphasizing the differences between their spectra and those obtained for synthetic images. Punctually, attention is focused on the concavity of real image spectra and on its interpretation in terms of the analyzed images. This lead us to the proposition of a segmentation method for water bodies.The method is tested and the results are compared with water masks of the regions under study. Comments are made about the limitations of the proposed method.

Management of Abnormally Invasive Placenta: One-center Experience
Authors: Penzhoyan Grigoriy , Novikova Vladislava 
Published: November 2017

ABSTRACT

Aim
To present one-center experience of the management of abnormally invasive placenta (AIP).

Materials and methods
This was a retrospective cohort study of clinical cases of abnormally invasive placenta (the AIP) in Perinatal Center (PC), which is part of General Hospital— Regional Clinical Hospital N2 of Krasnodar city, in the period from 2014 to August 2016.

Results
The total number of childbirth for the period was 24 078, and AIP was diagnosed in 0.17%. The average age of women was 31.5 ± 0.8 years. About 97.5% were multiparous women and 85% women in the previous pregnancy had childbirth by cesarean section (CS): One CS—41.18%, two—32.35%, and three—23.53%. An AIP was first diagnosed in pregnancy at 11 to 39 weeks of pregnancy by ultrasound or magnetic resonance imaging (MRI). Cesarean section performed in the conditions of the X-ray operating of the endovascular department. The relative risk (RR) for accurate diagnosis of AIP by ultrasound was 1.789 ± 0.709 [95% confidence interval (CI) 0.446–7.186], and for MRI RR was 0.944 ± 0.142 (95% CI 0.715–1.246). At CS, in 85% of women balloon dilatation of the iliac vessels was performed, in 15%, uterine artery embolization (UAE), and in 72.5%, metroplasty. In 15% of women with AIP were the cause of hysterectomy without adnexa. The total blood loss was 1152.56 ± 107.67 (4,000–35,000) mL or 15.539 ± 1.7374 (5,0000–58,330) mL/kg. Maximum blood loss was in women with placenta previa and its localization in the area of the scar on the uterus that required a hysterectomy.

Conclusion
Despite increasing incidence of AIP, it is possible to prevent massive blood loss during delivery by combined treatment using radiological endovascular procedures for devascularization of the lower pelvis. Early diagnosis of placental abnormalities with regionalized approach in perinatal health makes it possible not only to preserve the women's reproductive health and fertility but also to minimize postpartum hemorrhage.

Effect of Areca Nut Consumption on Hypoxia-inducible Factor-1 Alfa Expression in Patients with Oral Squamous Cell Carcinoma
Authors: Agarwal Kiran , Chauhan Anju , Prasad Jitender , Mehra Pravesh , Kumar Shilpa , Pahuja Bindiya K , Ahirwar Ashok K 
Published: November 2017

ABSTRACT

Introduction
Oral squamous cell carcinoma (OSCC) is a major health problem in Southeast Asia, including India. Areca nut chewing is a major health hazard in India, which has been implicated in the etiology of OSCC. Hypoxia-inducible factor-1 (HIF-1) is a major transcription factor involved in adaptation under hypoxic condition, a common finding in solid tumors. The present study was conducted to evaluate the effect of different habits including areca nut chewing on HIF-1 expression in patients with OSCC.

Materials and methods
It was a hospital-based observational case-control study. The study comprised 50 histologically proven cases of OSCC and 50 healthy controls. The HIF-1α level was measured by commercially available enzyme-linked immunosorbent assay (ELISA) in the blood samples. The data were analyzed using Statistical Package for the Social Sciences (SPSS) software version 20.

Results
The HIF-1α levels were found significantly higher in the patients with areca nut consumption in addition to other addictive habits. Isolated influence could not be discerned as there was only one patient who gave history of only areca nut chewing.

Conclusion
Our findings prove that HIF-1α expression is upregulated by areca nut chewing, which leads to worse prognosis. This calls for widespread awareness programs regarding the deleterious effects of areca nut chewing among the general population.

Study of Insulin Resistance in Women with Preeclampsia
Authors: Sonagra Amit D , Makandar Asmabi , Biradar Shivaleela M , Deba Zahoorunissa 
Published: November 2017

ABSTRACT

Introduction
The root cause of preeclampsia is placental ischemia due to impaired trophoblastic invasion in the uterine spiral arterioles. Ischemic placenta liberates various inflammatory mediators that cause widespread endothelial dysfunction leading to insulin resistance (IR). Increased IR in pregnant females can further lead to high occurrence of maternal and fetal complications.

Objectives
To compare and evaluate the role of measuring IR among women with preeclampsia and normal pregnancy.

Materials and methods
A total of 35 women with preeclampsia and 35 women with normal pregnancy were included in the study as cases and controls, respectively. Fasting plasma glucose (FPG) and fasting plasma insulin (FI) were measured and IR indices, such as FPG to FI ratio (FGIR), quantitative insulin sensitivity check index (QUICKI), and log FI were calculated. Unpaired Student's t-test was used for comparison. Statistical analysis was done using Statistical Package for the Social Sciences (SPSS) version 17.0.

Results
The mean FI and log FI were significantly higher while QUICKI and FGIR were significantly lower in cases when compared with controls (p < 0.001).

Conclusion
As disease advances, IR increases. There is increased risk of maternal and fetal complications in presence of increased IR. Screening of all hypertensive pregnancies for IR and timely intervention may help to improve outcome.

Effect of Gestational Age and Birth Weight on Serum Creatinine in the First Week of Newborn Life
Authors: Ayyala Vijaya L , Devabathina Narendra , Gurappagari Prakash 
Published: November 2017

ABSTRACT

Introduction
Serum creatinine concentration in health is essentially a function of muscle mass. We designed a prospective study to know the influence of gestational age and birth weight on creatinine in the first week of life.

Materials and methods
A total of 218 neonates were enrolled during a 2-year study period (May 2014—April 2016) at Kamineni Hospitals, Hyderabad, India. The study group was categorized based on gestational age [very preterm (VPT), preterm (PT), and term] and birth weight [very low birth weight (VLBW), low birth weight (LBW), and normal birth weight (NBW)]. The serum creatinine was assayed on the day of delivery in the mother and on days 0, 3, 5, and 7 in the neonates. The method of estimation of serum creatinine was by the modified kinetic Jaffe's reaction.

Results
Serum creatinine was high in the VPT neonates (28—33 weeks of gestational age) and VLBW neonates (<1.5 kg) on day 0. An increase in mean serum creatinine was recorded on day 3 in VPT and VLBW neonates. Mean neonatal serum creatinine in all the subgroups based either on gestational age or birth weight decreased on day 7.

Conclusion
The serum creatinine in the first week of a newborn should be interpreted cautiously as the kidneys are in the process of maturation. High serum creatinine in neonates with insignificant muscle mass is a reflection of maternal serum creatinine coupled with an immature kidney.

The Effect of Middle School Music Ensemble Participation on the Relationship Between Perceived School Connectedness, Self-Reported Bullying Behaviors, and Peer Victimization
Authors: Rawlings Jared R. 
Published: November 2017

Abstract
The purpose of this study was to examine the effect of middle school music ensemble participation on the relationship between school connectedness, bullying perpetration, and peer victimization. Participants (N = 470) selected for this study attended 2 middle schools located in central Illinois and voluntarily responded to the questionnaire by self-reporting demographic information, including their enrollment in a music course, and their behaviors as perpetrators and victims. Data were secured from a large-scale, 2-year randomized clinical trial funded by the Centers for Disease Control and Prevention (no. CE3240). Results indicated that nonensemble students in this sample perpetrate aggressive behaviors, on average, more frequently than do music ensemble students. While participant self-reports of bullying behaviors were relatively low, their perceptions of school connectedness were relatively high. Multiple-group structural equation modeling analyses demonstrated that a stronger negative association between perceptions of school connectedness and cyberbullying perpetration exist for music ensemble students than for adolescents not enrolled in a school-based music ensemble. Included are implications for the better support of preservice and in-service music teachers with regard to bullying in schools, alongside recommendations for continued examination of adolescent musicians’ levels of school connectedness and suggestions for future research.
Music Practice Instruction in Middle School Instrumental Ensembles: An Exploratory Analysis
Authors: Prichard Stephanie 
Published: November 2017

Abstract
The purpose of this study was to investigate the impact of music practice instruction on middle school band and orchestra students’ practice behaviors. Participants received 4 weeks of practice strategy instruction. Prior to, and following the intervention, self-reported practice strategy lists (N = 136) and video of individual practice sessions (n = 35) data were collected from 7th- and 8th-grade band and orchestra students. Self-reported data were coded and analyzed using descriptive statistics. More than 23 hours of video data (participants’ independent practice sessions) were analyzed using a practice frames evaluation scheme. Video data were further analyzed using an observational measure of self-regulation. Analyses revealed that participants identified and employed significantly more practice strategies following the intervention. Although repetition was the most commonly observed practice strategy overall, posttest practice sessions included more strategic forms of repetition (e.g., repetition of shorter sections and whole-part-whole repetition). Video analysis further revealed that following practice strategy instruction, participants exhibited significantly fewer and longer practice frames as well as more varied practice objectives. Weak relationships emerged between participants’ practice behaviors and their overall degree of self-regulation. Implications for classroom practice and future research are discussed.
Hillbilly Horror and the New Racism: Rural and Racial Politics in Orange Is the New Black
Authors: Scott Jessica 
Published: November 2017

Abstract
In this article, I raise questions about marginalization through representational techniques that make possible the vilification of the characters Pennsatucky and Vee from the first and second seasons of Orange Is the New Black (OITNB). I suggest that the show’s narrative advances a particular story about Appalachian Americans and about black Americans that justifies their marginalization through their portrayal as villains. Such representations rely on tropes that are well documented in histories of representations as well as in critical literature that examines the form that depiction of racial others takes in our contemporary moment. Particularly, Pennsatucky and Vee’s shared homophobia allows the show to characterize entire groups of people as outside the legibility of modernity.
Dramatizing Dualism: The Use of the Literary Double in Bolesław Prus’s The Doll
Authors: Wilmes Justin 
Published: November 2017

Abstract
Critics have devoted much attention to the complex ideological discourse of Bolesław Prus’s The Doll, justly noting that throughout the novel its protagonist, Stanisław Wokulski, is torn between impulses to romance, political revolt, science, business, and social progress. These notions, traditionally associated respectively with the Polish Romantic and Positivist movements, are articulated and championed in the novel by various characters, and indeed compete with one another within the conflicted psyches of individual characters. While critics have increasingly characterized The Doll as a proto-modernist, dialogic novel, what has received relatively little attention among scholars of this novel is the pervasive use of the literary double as a device for exploring Wokulski’s profound ambivalence—and by extension that of the transitional generation that he represents. Recurring appearances of Wokulski’s doppelgängers, or mental projections in the form of voices and visions, manifest his repressed desires, while the novel’s numerous quasi-doubles—characters bearing an uncanny resemblance—serve as a key organizing principle of the narrative, providing the protagonist with positive and negative insight into himself. But rather than attempting to reconcile these conflicting forces in monologic or dialectical fashion, Prus creates what literary theorist Mikhail Bakhtin calls a dialogic novelistic discourse, marked by multiple voices and viewpoints, unresolved ambiguities, and “unfinalized” characters, ever in the process of becoming. In such a reading, not only is Wokulski a transitional hero, negotiating social, ideological, and economic changes in Poland at the end of the nineteenth century, but the novel itself becomes a transitional work during the period of mature realism, demonstrating many formal features of the dialogic novel, and serving as a “bridge between the realist novel and modernist prose.”
Diasporic Filipinx Queerness, Female Affective Labor, and Queer Heterosocial Relationalities in Letters to Montgomery Clift
Authors: Sarmiento Thomas X. 
Published: November 2017

Abstract
With the narrow loss of Ferdinand “Bongbong” Marcos Jr.’s bid for the Philippine vice presidency in 2016, thirty years after his late father’s authoritarian regime crumbled, and with ongoing dissent against the senior Marcos’s burial later that year in the national cemetery for heroes, the ghosts of martial law continue to haunt the Philippines and its U.S. diaspora. Noël Alumit’s 2002 novel Letters to Montgomery Clift illustrates the psychic and affective ramifications of martial law displacement and resists the idea that such wounds have healed. Rather than focusing on the intersections of identity structures on the formation of an individual, this essay looks at the protagonist’s relationships to other people to explore the gendered and queered dimensions of diaspora and exile. While the story follows eight-year-old Bong Bong Luwad’s escape from the Philippines under the Marcos dictatorship, his queer sexual discovery in the United States, his coming to terms with his mental illness as a result of being separated from his birth parents, and, importantly, the imaginary relationship he develops with dead American actor Montgomery Clift, I read Alumit’s novel through a transnational queer feminist lens to foreground women’s central role in structuring the narrative. By focusing on the cross-gender affiliations that Bong develops with women, I renew queer engagements with feminist cultural critique. Ultimately, an attention to the affective ties between femininity and queerness in the diaspora engenders alternative accounts of subalternity and the palimpsestic histories of colonization and state terror that complicate how we understand displacement and exile in our contemporary moment.
Building Homes and Building Lives: Benefits of Involvement in the Shack Dwellers Federation of Namibia
Authors: Barnes Sandra L. , Cowser Angela 
Published: November 2017

Abstract
The Shack Dwellers Federation of Namibia (SDFN) was established in 1992 as a women-lead membership-based organization (MBOP) of the poor to secure affordable housing and infrastructure services through savings and sweat-equity groups across thirteen Namibian regions. Yet, to our knowledge, a study on this organization that focuses on the voices of members to assess how they understand and prioritize Federasi involvement has not been performed. Theoretically informed by black feminism, this multidisciplinary, mixed-methodological project considers the benefits of participation for 281 members. Although anecdotal information suggests that the vast majority of women participate to secure stable housing, content and bivariate analyses illustrate the primacy of psychological benefits and collective mobilization.
Teksten som problem i 8A. Affinitet og tiltrekningskraft i samtaler om «Brønnen»
Authors: Sønneland Margrethe , Skaftun Atle 
Published: November 2017

Denne artikkelen utforsker hva som skjer når ungdomsskoleelever får arbeide med fagspesifikke problemer i norsk på egen hånd. Problemet elevene møter og samtaler om er novellen «Brønnen» av Roy Jacobsen, en tekst som byr på litteraturfaglige utfordringer knyttet til form og innhold. Analysen gjennomføres i to steg. I første steg rettes oppmerksomheten mot timen og alle samtalene i klasserommet som fenomenologisk helhet, for å fange opp og formidle forskernes opplevelse av stemning og engasjement blant elevene. Deretter analyseres én av samtalene mer inngående som et kritisk case for å underbygge og validere den første analysen. Analysene gjøres i lys av James Paul Gees diskursanalytiske building tasks, med særlig interesse for tilskriving av signifikans – det vi vil kalle verdsetting. Analysen viser at elevene verdsetter å samtale om fagspesifikke problemer på egen hånd, og dette diskuteres i lys av James Paul Gees og Elisabeth Hayes’ læringsteori om affinitetsrom (2012).Nøkkelord: fagspesifikke problemer, affinitetsrom, fagspesifikk literacy-praksis, litteratursamtaler AbstractThis article explores what happens when pupils in lower secondary school work with subject-specific problems in the Norwegian subject by themselves. The problem that these students encounter and talk about, is the short story “Brønnen” by Roy Jacobsen. This short story is a text that offers literary challenges relating to both style and content. The analysis is conducted in two steps. First, the attention is drawn to the classroom and to all the conversations understood as a phenomenological whole. This is done in order to capture and convey the researchers' experience of mood and engagement among the students. Second, one of the conversations, seen as a critical case, is analysed in depth for the purpose of underpinning and validating the first analysis. This analysis is conducted in the light of James Paul Gee's discourse-analytical building tasks, paying particular attention to significance. The analysis shows that students appreciate being provided with opportunities to explore subject-specific problems by themselves. James Paul Gee’s and Elisabeth Hayes’ (2012) learning theory on affinity spaces provides the backdrop for the discussion of this finding.Keywords: subject-specific problems, affinity spaces, disciplinary literacy-practice, literary conversations

L’archivage du Web : bibliothèques et archives à la croisée des chemins
Authors: Oury Clément 
Published: November 2017

Le Web est devenu, en quelques années, un support essentiel de diffusion de l’information. Cependant, la nature même du Web remet en cause une des fonctions principales des institutions culturelles : la conservation du patrimoine. Cela est d’autant plus le cas pour les bibliothèques nationales qu’elles sont souvent en charge, au titre de leur mission de dépôt légal, de la collecte et de la conservation de l’ensemble de la production scientifique et culturelle d’une nation. Pour faire face aux défis que représentait l’archivage d’une masse de données aussi vaste et aussi hétérogène, les bibliothèques ont donc été amenées à questionner leurs approches. Elles ont dû notamment s’inspirer des démarches d’autres communautés professionnelles, particulièrement celle des archivistes. La terminologie et certaines méthodes archivistiques ont souvent été employées : accent mis sur la collecte, pratique de l’échantillonnage… De fait, les collections constituées ont elles-mêmes un statut hybride, tenant à la fois de la publication et du document d’archives. Puisque les archives du Web sont des artefacts, des agrégats complexes, la question de l’authenticité prend également une place déterminante. L’ouverture à de nouvelles approches– qui ne signifie pas forcément une fusion des identités professionnelles – doit inciter à la coopération entre institutions.
