Informal Labours in Kolkata City: Migration from Undivided Bihar and Uttar Pradesh

Migration takes place due to various social, cultural, economic or political reasons. Previous Census reports of India show that employment-induced out-migration is a common feature of several states like Bihar, Jharkhand, Uttar Pradesh, and other states. In the case of Kolkata, informal labours have enormous employment opportunities in big business centres and small manufacturing units of the city. With the help of D-series Census Data of the years 1961, 1971, 1981, 1991, 2001 and 2011, this study focuses on the migration pattern and the reasons for migration to Kolkata. Secondary data fails to give an idea about the migration pattern of non-Bengali informal labours in the city. Through intensive field survey, the present study tries to identify the dominance of non-Bengali single (without family) male labour migration and to explore the migration streams to the informal sectors of Kolkata. With the help of both secondary data on migration over different decades and by using the primary data, the article argues that non-Bengali migrants represent the informal labour community in Kolkata especially from undivided Bihar and Uttar Pradesh, and the pattern of migration is mainly occupation-induced single male labour migration

Ideology and Class Division in Veronica Roth’s Divergent

The paper attempts to overview the ideology and the class division amongst factions in the novel. The ideology of the five factions in the future city of Chicago is embedded with self traits which dictates that everyone must fit into one dominant trait. The classification by traits or personalities makes clear provision that society will run as it is expected by the leader of the faction.  The Divergent of Veronica Roth postulates the depiction of the utopia society that turns Dystopia by the insurgent led by Tris a character that possesses all the qualities and traits of the faction.  The culture and the ideology of bourgeois and slave’s society prevail vividly in the novel which is indicated by the ruling faction, Erudite as the bourgeois while the subjugated faction, Abnegation as the slave society. This paper utilizes the descriptive approach to meticulously break down the events by selecting and highlighting the occurrences in the novel as the way of obtaining the data. The theory of ideology by Raymond Williams (1977) was used in this paper to expose the core or base of cultural ideology amongst the classes. The paper finds out that the every faction has its own ideologies even though they were rooted from the same founding fathers

The Socialization of Indian Scientific Writers Into Western Scientific Discourse Communities.

This research studies the socialization of Indian science writers into western discourse communities. More specifically, it seeks to identify the writing problems that beginner Indian science writers face and the strategies that they adopt in overcoming them while writing dissertations or research articles. Primary information was gathered by interviewing 11 Indian graduate students and 17 faculty members from India (West Bengal) and the USA on the basis of a five-page questionnaire. Respondents were classified into three groups according to their places of training and writing skills. Three to five sets of rough drafts from each group were studied to note textual revisions and review comments as a supplementary source of information. A fourth group consisting of five native-speaking faculty members was also interviewed on the basis of a separate questionnaire. This research demonstrates that while beginner Indian respondents share many problems with other nonnative and native speakers alike, their problems have roots in Indian culture and education. These factors merit consideration for future pedagogical instruction. Variable language policies and schooling systems produce students with varying writing proficiencies. Initial training in the text-based reproductive and authoritarian mode combined with a heavy literary emphasis is viewed as an obstacle towards writing an effective argument or a critical synthesis. Problems such as validating claims and inferences arise from weak rhetorical skills and a lack of awareness for the rhetorical organization of the traditional Introduction-Method-Results-Discussion format in scientific writing, including the role of citations as a rhetorical tool. Cultural traits such as providing contextual information combined with a lack of scientific writing instruction produce digressive writing. While unlike other nonnative writers, beginner respondents write drafts in English, their minor but recurrent problems include ineffective sentence construction, repetition, flowery language, weak cohesion and incorrect article use. Planning extensively, using mathematical language, extending vocabulary, and writing shorter sentences are identified as successful strategies that are adopted to overcome writing obstacles. Reading and using advisorial feedback are other beneficial strategies that facilitate the socialization process. Writing instruction on developing critical, argumentative and rhetorical skills is recommended as a corrective pedagogy

Illocutionary Acts in President Rodrigo Duterte’s Speech.

This research attempts to figure out the speech act of President of The Republic of The Philippines, Rodrigo Duterte, particularly in identifying types of the Illocutionary act and Perlocutionary act in SONA Forum. The researcher is keen to explore duterte’s speech because Duterte is notorious for his unfavorable remarks. Therefore, by investigating his speech through the analysis of his speech act in the selected speech, the researcher will prove whether the speech contains the perlocutionary acts of insulting or not. This research also focuses on utilizing Searle’s theory on Illocutionary acts exemplifies 5 different types of illocutionary acts namely Assertive which is divided into stating, suggesting, boasting, complaining and claiming. Another type is Directives which comprises of ordering, commanding, requesting, advising and recommending. Expressive type comprises thanking, congratulating, pardoning, blaming, praising, and condoling. Commisive type includes promising, vowing, and offering. The last type is Declaration. The researchers use descriptive qualitative method by doing transcription of the speech and meticulously analyze every word

Pediatric duodenal cancer and biallelic mismatch repair gene mutations

Gastrointestinal malignancies are extremely rare in the pediatric population, and duodenal cancers represent an even more unusual entity. Intestinal cancers in young adults and children have been observed to be associated with functional deficiencies of the mismatch repair (MMR) system causing a cancer-predisposition syndrome. We report the case of a 16-year-old female with duodenal adenocarcinoma and past history of medulloblastoma found to have a novel germline bialleleic truncating mutation (c.[949C>T]+[949C>T]) of the PMS2 gene.

O-Antigen Biosynthesis: Hitting the Sweet Spot for a Q Fever Vaccine

Poster presented at the 2017 Defence and Security Doctoral Symposium.Coxiella burnetii, the causative agent of Q fever, is a pathogen with a worldwide distribution. Biological material shed from ruminant infections contaminates dirt and dust, which can cause infection on inhalation. Humans generally present with flu-like symptoms, however, patients can develop life-changing maladies such as hepatitis, chronic fatigue, and endocarditis. Q fever was initially identified as a military problem when thousands were affected during WWI. More recently, Q fever has been recognised as a problem in UK troops returning from Afghanistan. C. burnetii is classified as a CDC category B bioterrorism agent, the second highest category, yet there is no Q fever vaccine licensed in the UK/EU/US. For C. burnetii, the lipopolysaccharide (LPS) is the main determinant of virulence, and many of the most effective modern vaccines target such sugar structures. Furthermore, the sugars that comprise the C. burnetii LPS are highly unusual, making this the primary target for vaccine development. In order to facilitate production of a subunit vaccine, focus is on elucidating the pathways for biosynthesis of two very rare sugars, virenose and dihydrohydroxystreptose (DHHS). Therefore in addition to providing the basis for a novel Q fever vaccine, for livestock and humans, this project will highlight novel biochemistry

Performance of colloidal CdS sensitized solar cells with ZnO nanorods/nanoparticles

As an alternative photosensitizer in dye-sensitized solar cells, bovine serum albumin (BSA) (a nonhazardous protein) was used in the synthesis of colloidal CdS nanoparticles (NPs). This system has been employed to replace the commonly used N719 dye molecule. Various nanostructured forms of ZnO, namely, nanorod and nanoparticle-based photoanodes, have been sensitized with colloidal CdS NPs to evaluate their effective performance towards quantum dot sensitized solar cells (QDSSCs). A polysulphide (S-x(2-))-based electrolyte and CuxS counter electrode were used for cell fabrication and testing. An interesting improvement in the performance of the device by imposing nanorods as a scattering layer on a particle layer has been observed. As a consequence, a maximum conversion efficiency of 1.06% with an open-circuit voltage (V-OC) of 0.67 V was achieved for the ZnO nanorod/nanoparticle assembled structure. The introduction of ZnO nanorods over the nanoparticle led to a significant enhancement of the overall efficiency compared to the corresponding bare nanoparticles

Role of sialidase in glycoprotein utilization by Tannerella forsythia

The major bacterial pathogens associated with periodontitis include Tannerella forsythia. We previously discovered that sialic acid stimulates biofilm growth of T. forsythia, and that sialidase activity is key to utilization of sialoconjugate sugars and is involved in host–pathogen interactions in vitro. The aim of this work was to assess the influence of the NanH sialidase on initial biofilm adhesion and growth in experiments where the only source of sialic acid was sialoglycoproteins or human oral secretions. After showing that T. forsythia can utilize sialoglycoproteins for biofilm growth, we showed that growth and initial adhesion with sialylated mucin and fetuin were inhibited two- to threefold by the sialidase inhibitor oseltamivir. A similar reduction (three- to fourfold) was observed with a nanH mutant compared with the wild-type. Importantly, these data were replicated using clinically relevant serum and saliva samples as substrates. In addition, the ability of the nanH mutant to form biofilms on glycoprotein-coated surfaces could be restored by the addition of purified NanH, which we show is able to cleave sialic acid from the model glycoprotein fetuin and, much less efficiently, 9-O-acetylated bovine submaxillary mucin. These data show for the first time that glycoprotein-associated sialic acid is likely to be a key in vivo nutrient source for T. forsythia when growing in a biofilm, and suggest that sialidase inhibitors might be useful adjuncts in periodontal therapy

Zoonoses under our noses.

One Health is an effective approach for the management of zoonotic disease in humans, animals and environments. Examples of the management of bacterial zoonoses in Europe and across the globe demonstrate that One Health approaches of international surveillance, information-sharing and appropriate intervention methods are required to successfully prevent and control disease outbreaks in both endemic and non-endemic regions. Additionally, a One Health approach enables effective preparation and response to bioterrorism threats
