Social media influencers, post feminism and neoliberalism: How mum bloggers' 'playbour' is reshaping public relations
Venue: Public Relations Inquiry
Year: 2019

The rise of blogging mothers as precariat workers conducting 'playbour' a combination of play and labour, and as subjects of neoliberalism, requires a re examination of virtually mobile mothers and their role in 21st century society. At the same time, public relations (PR) and marketing practitioners are grappling with how to interact and 'work' with these, among other, social media influencers who are increasingly seen as able to sell products and ideas through their blogs, Instagram, Facebook and other social media platforms. The relatively new relationships between PR practitioners and social media influencers raise questions of unequal power and vulnerability for both the largely amateur influencers and the PR practitioners. The relationship between the two means that ethical questions around exploitation, authenticity, professionalism and control have arisen, with both sides feeling their way in new terrain. This article uses the concepts of precarity and liminality and applies them to a group of 'mommy/mummy/mum bloggers' that is, blogging mothers of young children, negotiating their identities as mothers, and moving beyond their homes using social media to, in part, create a sense of belonging (but also, in some cases, to make money) The article is based on the author's own longitudinal digital ethnography within online influencer territory, and includes mainstream and online media reports and interviews with both mum bloggers and PR practitioners. It is argued that the marketisation of motherhood within a dominant culture of neoliberalism means that practitioners may wrongly assume that mum bloggers are acting freely to engage with entrepreneurial endeavours.
Dynamic Maintenance of Approximations Under a Rough set Based Variable Precision Limited Tolerance Relation
Venue: J. Multiple Valued Log. Soft Comput.
Year: 2012

Approximations are basic operators in rough sets theory. Both certain and uncertain rules can be well induced from different regions partitioned by approximations. In the dynamic change of an information system, approximations of a concept vary with time. In this paper, we extend the variable precision rough sets to Variable Precision Limited Tolerance Relation based Rough Sets (VPLTRRS) in Incomplete Information Systems (IIS) The VPLTRRS has tolerance to errors and can deal with data with missing values. We propose new definitions of coarsening and refining attribute values in IIS and present properties of approximations in terms of coarsening and refining attribute values in IIS. We further develop algorithms to dynamic maintenance of approximations under VPLTRRS. With examples to explain the incremental updating method, we validate by extensive experimental evaluation results the effectiveness of the proposed approach for dynamic maintenance approximations under VPLTRRS.
Impact of tillage and crop establishment methods on crop yields, profitability and soil physical properties in rice wheat system of Indo Gangetic Plains of India
Venue: Soil Use and Management
Year: 2019

Conservation agriculture (CA) based on best bet crop management practices may increase crop and water productivity, as well as conserve and sustain soil health and natural resources. In a 2 year study, we assessed the effects of tillage and crop establishment (TCE) methods on productivity, profitability and soil physical properties in a rice wheat (RW) system. The six TCE treatments were used to study the impact, which are puddled transplanted rice followed by conventionally tilled wheat (CTPR CTW) direct seeded rice on the flat followed by zero till wheat (CTDSR ZTW) zero till direct seeded rice with residue followed by zero till wheat with residue (ZTDSR+R ZTW+R) transplanted rice after rotavator puddling followed by zero till wheat (RTTPR ZTW) transplanted rice after rotavator puddling followed by rotary till wheat (RTTPR RTW) and farmer practice rice wheat (FP RW) Result of the study revealed that mean rice yield was not significantly affected by different TCE methods. Wheat planted with ZTDSR+R ZTW+R gave 30% larger grain yield than FP RW. Overall, among all the TCE treatments, the RW system yields and net returns were maximum under ZTDSR+R ZTW+R. The fastest mean infiltration rate (0.10 cm hr 1) was registered in ZTDSR+R ZTW+R plots, whereas the slowest was in FP RW plots (0.05 cm hr 1) Bulk density at 15 20 cm soil depth was least in ZTDSR+R ZTW+R (1.70 Mg m 3) and greatest in FP RW (1.73 Mg m 3) Results from this study revealed that conventionally tilled (CT) and transplanting of rice could be successfully replaced by adoption of the profitable double ZT RW system.
Author aware Aspect Topic Sentiment Model to Retrieve Supporting Opinions from Reviews
Venue: EMNLP
Year: 2017

User generated content about products and services in the form of reviews are often diverse and even contradictory. This makes it difficult for users to know if an opinion in a review is prevalent or biased. We study the problem of searching for supporting opinions in the context of reviews. We propose a framework called SURF, that first identifies opinions expressed in a review, and then finds similar opinions from other reviews. We design a novel probabilistic graphical model that captures opinions as a combination of aspect, topic and sentiment dimensions, takes into account the preferences of individual authors, as well as the quality of the entity under review, and encodes the flow of thoughts in a review by constraining the aspect distribution dynamically among successive review segments. We derive a similarity measure that considers both lexical and semantic similarity to find supporting opinions. Experiments on TripAdvisor hotel reviews and Yelp restaurant reviews show that our model outperforms existing methods for modeling opinions, and the proposed framework is effective in finding supporting opinions.
Exports and Productivity The Role of Imported Inputs and Investment in R&D
Year: 2020

The empirical evidence on within firm productivity improvements from exports has largely been understated because the measures of revenue productivity used do not account for pricing heterogeneity across firms. Using a panel of Indian firms, the analysis in this paper controls for firm variation in prices and uses proxy methods to retrieve measures of productivity that reflect physical productivity. Within firm productivity changes from export entry are computed using a difference in differences matching estimator. The findings show that, over a six year period, the difference in productivity growth between export entrants and their non exporter counterparts is about 11 percentage points. Thus, productivity improvements from selling in international markets have largely been understated in the export productivity empirical literature. This difference in productivity growth is decomposed into two channels. About 15 percent of the difference in productivity growth is explained by higher imports of intermediate inputs, and about 85 percent is explained by investment in research and development. The evidence suggests that investment in research and development is an important source of within firm productivity gains even in developing countries.

Enhancing students interest in English language via multimedia presentation
Year: 2016

It is often said that interest is the best teacher. In learning English language, sometimes students have certain barriers of understanding and they often reject to learn. As a result, it is very hard for many students to improve their English language learning level. To make the students learn more autonomously and effectively, it is necessary to make them be interested in learning. With new technological tools continuing to emerge, multimedia plays very important role in English language teaching. The use of Multimedia presentation offers a potentially venue for improving student understanding about language. This paper discusses changing trends in English language teachinglearning, highlights the concept of multimedia, explains theoretical basis of multimedia English teaching and also states the significant role of multimedia in motivating learner's interest in English
Transcriptome analysis of mycobacteria in sputum samples of pulmonary tuberculosis patients
Venue: PloS one
Year: 2017

Pulmonary tuberculosis, the disease caused by Mycobacterium tuberculosis, still retains a top rank among the deadliest communicable diseases. Sputum expectorated during the disease continues to be a primary diagnostic specimen and also serves as a reservoir of bacteria. The expression pattern of mycobacteria in sputum will lead to an insight into bacterial adaptation at the most highly transmissible stage of infection and can also help in identifying newer diagnostic as well as drug targets. Thus, in the present study, a whole genome microarray of Mycobacterium tuberculosis was used to elucidate the transcriptional profile of mycobacteria in the sputum samples of smear positive pulmonary tuberculosis patients. Overall, the mycobacteria in sputum appeared to be in a low energy and low replicative state as compared to in vitro grown log phase M. tb with downregulation of genes involved in ATP synthesis, aerobic respiration and translational machinery. Simultaneously, downregulation was also seen in the genes involved in secretion machinery of mycobacteria along with the downregulation of genes involved in the synthesis of phthiocerol dimycocerosate and phenol glycolipids. In contrast, the majority of the genes which showed an upregulation in sputum mycobacteria were of unknown function. Further identification of these genes may provide new insights into the mycobacterial behavior during this phase of infection and may help in deciphering candidates for development of better diagnostic and drug candidates.

Fast and Maliciously Secure Two Party Computation Using the GPU
Venue: ACNS
Year: 2013

We describe, and implement, a maliciously secure protocol for two party computation in a parallel computational model. Our protocol is based on Yao's garbled circuit and an efficient OT extension. The implementation is done using CUDA and yields fast results for maliciously secure two party computation in a financially feasible and practical setting by using a consumer grade CPU and GPU. Our protocol further uses some novel constructions in order to combine garbled circuits and an OT extension in a parallel and maliciously secure setting.
Post earthquake structural design for fire a New Zealand perspective
Year: 2012

On Tuesday 22 February 2011, a 6.3 magnitude earthquake struck Christchurch, New Zealand's second largest city. The 'earthquake' was in fact an aftershock to an earlier 7.1 magnitude earthquake that had occurred on Saturday 4 September 2010. There were a number of key differences between the two events that meant they had dramatically different results for Christchurch and its inhabitants. The 22 February 2011 event resulted in one of New Zealand's worst natural disasters on record, with 185 fatalities occurring and hundreds more being injured. In addition, a large number of buildings either collapsed or were damaged to the point where they needed to be totally demolished. Since the initial earthquake in September 2010, a large amount of building related research has been initiated in New Zealand to investigate the impact of the series of seismic events the major focus of these research projects has been on seismic, structural and geotechnical engineering matters. One project, however, conducted jointly by the University of Canterbury, the Fire Protection Association of New Zealand and BRANZ, has focused on the performance of fire protection systems in the earthquakes and the effectiveness of the systems in the event of post earthquake fires occurring. Fortunately, very few fires actually broke out following the series of earthquake events in Christchurch, but fire after earthquakes still has significant implications for the built environment in New Zealand, and the collaborative research has provided some invaluable insight into the potential threat posed by postearthquake fires in buildings. As well as summarising the damage caused to fire protection systems, this paper discusses the flow on effect for designing structures to withstand post earthquake fires. One of the underlying issues that will be explored is the existing regulatory framework in New Zealand whereby structural earthquake design and structural design for fire are treated as discrete design scenarios.
Letter to the Editor: Obesity as a risk factor for greater severity of COVID 19 in patients with metabolic associated fatty liver disease
Venue: Metabolism
Year: 2020

Coronavirus disease 2019 (COVID 19) has been declared a pandemic in 2020. Patients with metabolic associated fatty liver disease (MAFLD) are often obese and have additional metabolic risk factors which may aggravate the severity of respiratory diseases and of COVID 19. This study aims to investigate the association between MAFLD and COVID 19 severity.  214 patients with laboratory confirmed COVID 19 aged between 18 and 75 years from three hospitals in Wenzhou, China were consecutively enrolled. Sixty six patients with MAFLD were included in the final analysis. COVID 19 was diagnosed as a positive result by high throughput sequencing or real time reverse transcriptase polymerase chain reaction assay of oropharyngeal swab specimens. COVID 19 severity was assessed during hospitalization and classified as severe and non severe based on the current management guideline. All patients were screened for fatty liver by computed tomography and subsequently diagnosed as MAFLD according to a recent set of consensus diagnostic criteria. Obesity was defined as BMI >25 kg/m2.  The presence of obesity in MAFLD patients was associated with a 6 fold increased risk of severe COVID 19 illness (unadjusted OR 5.77, 95% CI 1.19 27.91, p .029) Notably, this association with obesity and COVID 19 severity remained significant (adjusted OR 6.32, 95% CI 1.16 34.54, p .033) even after adjusting for age, sex, smoking, diabetes, hypertension, and dyslipidaemia.  Our data demonstrate that the risk of obesity to COVID 19 severity is greater in those with, than those without MAFLD.
Implementation and acceptance of national language policy: the case of Dutch (1750 1850)
Venue: Language Policy
Year: 2019

The paper discusses implementation and acceptance as crucial elements of a historical sociolinguistic reappraisal of Haugen's well known theory of standardization. The case study that we focus on is the Dutch language in the second half of the eighteenth and the first half of the nineteenth century. In this period, Dutch became an object of political control. Significant aspects of the nationalization of language were the establishment of an officialized orthography (1804) and grammar (1805) which were to be used in the national school system. Education was the societal domain in which the national government tried to secure the transmission of the national language norms. We study the implementation and acceptance of official language norms from two perspectives, viz. by focusing on teaching materials developed for the new national school system, and by analyzing a recently compiled corpus of original language data from this period. We argue that implementation and acceptance, though relatively understudied topics in standardization studies, can usefully be operationalized, and turned into empirical questions that historical sociolinguistic analysis can answer.
Intermolecular ab initio potential and spectroscopy of the ground state of HeI2 complex revisited.
Venue: The journal of physical chemistry. A
Year: 2009

The structure, energetics, and spectroscopy of ground state HeI(2) molecule are analyzed from first principles. Ab initio methodology at CCSD(T) level of theory was employed, and large basis sets were used to compute the interaction energies. Scalar relativistic effects were accounted for by relativistic effective core potentials for the iodine atoms. Recent experimental investigations of the HeI(2) rovibronic spectra have estimated the ground state binding energies of 16.6 0.6 and 16.3 0.6 cm( 1) for the T shaped and linear isomers, respectively. Given the extremely small difference between the two conformers, special attention was paid in the choice of basis sets used and the extrapolation schemes employed, as well as the fitting process for its analytical representation. The complete analytical form is provided, and variational fully quantum mechanical calculations were carried out by using the new parametrized surface, to evaluate vibrationally averaged structures and binding energies for the different conformers. The results obtained are in good accord with recent data available from experimental investigations of the He I(2) rovibronic spectra.
[Impact of the 21 gene recurrence score assay in clinical treatment and prognosis analysis for patients with hormone receptor positive early stage breast cancer]
Venue: Zhonghua zhong liu za zhi [Chinese journal of oncology]
Year: 2018

To explore the association between the 21 gene recurrence score (RS) and clinicopathologic characteristics as well as prognosis in patients with axillary lymph node negative, hormone receptor (HR) positive breast cancer.  The clinicopathologic data of 439 early breast cancer patients who underwent 21 gene RS testing was retrospectively analyzed. According to the 21 gene RS, the patients were divided into low risk (295 cases) intermediate risk (111 cases) and high risk (33 cases) group. The relationship between the 21 gene RS and clinicopathological characteristics, treatment, recurrence and metastasis was analyzed. Univariate and multivariate statistical analyses were used to analyze the risk factors for relapse free survival (RFS)  Tumor grade, estrogen receptor (ER) progesterone receptor (PR) and Ki 67 index were significantly different among the 3 risk cohorts (P<0.001 for all) After a median follow up of 32 months, the recurrence rate in low risk group (3.7% was significantly lower than that in the intermediate high risk group (9.0% the locoregional recurrence (LRR) rate of low, intermediate and high risk group was 2.4% 6.3% and 9.1% and the distant metastasis (DM) rate in low risk group was 1.4% and 2.1% in the intermediate high risk group. Univariate analysis showed RS, ER status and endocrine therapy were prognostic factors for RFS (P<0.05 for all) Multivariate analysis showed that RS was an independent significant predictor for RFS (P=0.04)  The 21 gene RS is related to tumor grade, ER, PR and Ki 67 index. RS is an independent risk factor for RFS in patients with hormone receptor positive early stage breast cancer.
Semantic classification based clothing image retrieval
Venue: 2012 International Conference on Audio, Language and Image Processing
Year: 2012

Performance of content based image retrieval technology used in clothing image retrieval cannot meet user's requirement due to the `semantic gap' between low level visual features and the richness of human semantics and it's time consuming to searching images in a growing number on the internet. In order to reduce the `semantic gap' and improve the searching speed, this paper introduces a novel clothing image retrieval method based on color semantic classification. In this method, database images are classified into different categories with color semantic features and indexed by their visual features. In the retrieval process, images with the same semantic category are selected as candidates and further ranked by their visual features. The sematic information can also be used integrated with text information labeled on the internet. Experimental results demonstrate our proposed method provides promising retrieval performance in less time than previous methods.
Polyps of the jellyfish Aurelia aurita are unaffected by chronic exposure to a combination of pesticides.
Venue: Environmental toxicology and chemistry
Year: 2020

Pesticides are a major contaminant in coastal waters and can cause adverse effects in marine invertebrates such as jellyfish. Most studies have investigated short term responses of organisms to unrealistically high concentrations of pesticides; however, chronic exposure to persistent low concentrations, which are more likely to occur in the environment, are rarely analyzed. Here, we tested the response of polyps of the Moon jellyfish Aurelia aurita, to environmental concentrations of the herbicide atrazine and the insecticide chlorpyrifos, individually and in combination, over nine weeks. We hypothesized that exposure to individual pesticides would reduce rates of asexual reproduction and alter polyps' metabolite profiles, and that the results would be more severe when polyps were exposed to the combined pesticides. Polyps survived and reproduced (through budding) in all treatments and no differences among treatments were observed. Proton nuclear magnetic resonance (1 H NMR) spectroscopy revealed no difference in profiles of polar metabolites of polyps exposed to the individual or combined pesticides. Our results suggest that A. aurita polyps are unaffected by chronic exposure to atrazine and chlorpyrifos at concentrations recommended as being protective by current Australian water quality guidelines.
