The content and access dynamics of a busy web site: findings and implicatins

In this paper, we study the dynamics of the MSNBC news site, one of the busiest Web sites in the Internet today. Unlike many other efforts that have analyzed client accesses as seen by proxies, we focus on the server end. We analyze the dynamics of both the server content and client accesses made to the server. The former considers the content creation and modification process while the latter considers page popularity and locality in client accesses. Some of our key results are: (a) files tend to change little when they are modified, (b) a small set of files tends to get modified repeatedly, (c) file popularity follows a Zipf-like distribution with a parameter &agr that is much larger than reported in previous, proxy-based studies, and (d) there is significant temporal stability in file popularity but not much stability in the domains from which clients access the popular content. We discuss the implications of these findings for techniques such as Web caching (including cache consistency algorithms), and prefetching or server-based ``push'' of Web content.
Channel Aware Aloha with Imperfect CSI

Channel aware medium access protocols perform decisions primarily based on the instantaneous channel state information (CSI) available. In practice, channel measurements and quantization introduce distortion in the available CSI at the transmitter. In this paper, we investigate the effect of imperfect CSI on the asymptotic throughput of a particularly important medium access protocol - the channel aware Aloha. We show that any degree of uncertainty in the channel estimate leads to zero throughput asymptotically in the existing single carrier Aloha scheme; however, multicarrier diversity is effective in compensating for lack of perfect CSI.
The rising trend of asthma prevalence in urban school children of Jaipur: A questionnaire based study

Objective: The objective of this study is to assess the current prevalence of asthma and other allergies in urban school children of Jaipur and further to assess the increasing trend. Materials and Methods: A cross-sectional study was conducted among 2925 urban school children (5–15 years) of Jaipur using a modified school-based-allergy and asthma screening questionnaire. Results: Among 2925 children screened, 24% (702) were labeled as probable asthmatics of which 18.2% (532) were diagnosed to have asthma, and only 6.2% had previously diagnosed asthma by physician. Conclusion: The current prevalence of asthma is 18.2% which is on a rapidly rising trend and despite its high prevalence; the disease still remains highly underdiagnosed in children.
Global existence and blow-up of weak solutions for a class of fractional p-Laplacian evolution equations

Abstract In this paper, we study the fractional p-Laplacian evolution equation with arbitrary initial energy, ut(x,t)+(−Δ)psu(x,t)=f(u(x,t)),x∈Ω,t>0, $$\begin{array}{} \displaystyle u_t(x,t) + (-{\it\Delta})_p^s u(x,t) = f(u(x,t)), \quad x\in {\it\Omega}, \,t \gt 0, \end{array} $$ where (−Δ)ps $\begin{array}{} (-{\it\Delta})_p^s \end{array} $ is the fractional p-Laplacian with p>max{2NN+2s,1} $\begin{array}{} p \gt \max\{\frac{2N}{N+2s},1\} \end{array} $ and s ∈ (0, 1). Specifically, by the modified potential well method, we obtain the global existence, uniqueness, and blow-up in finite time of the weak solution for the low, critical and high initial energy cases respectively.
Effect of vitamin D3 in treating hyperthyroidism in patients with graves’ disease

Background Graves’ disease (GD) is an autoimmune disease characterized by hyperthyroidism secondary to circulating autoantibodies. Multiple factors contributed to its etiology, including genetic and environmental factors. The role of vitamin D is well-known in calcium metabolism and skeletal homeostasis. Vitamin D was shown to be a modulator in both innate and adaptive immunity. There is a link between vitamin D deficiency and various autoimmune diseases. The prevalence of vitamin D deficiency was reported to be common in patients with GD. Interestingly, vitamin D deficiency is found to be associated with higher thyroid volume in patients with newly-onset GD. However, vitamin D deficiency relationship with GD remains a controversial issue. Objective The objective of this study was to evaluate the effect of vitamin D supplementation in GD with and without ophthalmopathy. Patients and methods A randomized prospective study was conducted on 60 adult patients with GD aged 20–40 years. Group 1 comprised 20 patients with GD receiving a daily dose of 30 mg of methimazole alone. Group 2 comprised 40 patients with GD receiving the same dose of methimazole, supplemented with intramuscular injection of vitamin D3 200 000 IU/month for 3 months. Patients were followed up over a 3-month duration. Results There was hypovitaminosis D in all participants with a percentage of vitamin D deficiency (vitamin D level: <20 ng/ml) of 73.9% in male and 54.1% in female and a vitamin D insufficiency (vitamin D level: 20–29 ng/ml) of 26.1% in male and 45.9% in female. Vitamin D was significantly correlated with thyroid volume and degree of exophthalmos. On vitamin D supplementation, group 2 had significantly lower thyroid volume and better effect on the degree of exophthalmos. Conclusion Vitamin D supplementation for GD has a favorable effect on thyroid volume and on the degree of exophthalmos.
Foreign Ownership, R&D and Firm Innovation in ASEAN Countries: A Generalized Ordered Logit Model

Abstract The study investigates the direct effects of foreign ownership and R&D on firm innovation and the moderating effects of R&D on the foreign ownership–innovation relationship in ASEAN countries. This research focus is important as ASEAN countries have received a large amount of inward FDI as part of their export-led growth strategy, and FDI can bring both benefits and negative impacts for the host country. To the authors’ knowledge, this study contributes as the first attempt to examine this topic in ASEAN. The study employs a novel approach (i.e., generalized ordered logit model (GOLM)) to deal with the restrictive “parallel regression/proportional odds” assumption of the standard ordered logit model (OLM), which has not been adequately addressed in previous studies on the foreign ownership–innovation relationship. The findings show that foreign ownership relates negatively to the possibility of radical innovation, while R&D relates positively to the possibility of radical innovation. In addition, R&D positively moderates the effect of foreign ownership on the possibility of radical innovation. The findings verify the important role of R&D as a mechanism for absorptive capacity building in the foreign ownership–innovation relationship, which has been under-researched in prior studies on the role of foreign ownership in firm innovation. The policy implications emphasize that ASEAN governments should have more technological regulations and incentives to encourage foreign investors to bring advanced technologies and invest more in R&D.
Social Innovation Living Labs as Platforms to Co-design Social Innovations

Abstract Objective: The aim of the research is to develop a new original concept of social innovation lab based on the concept of living labs seen from the perspective of design-led approach to management and innovation. Methodology: The research was carried out with use of non-empirical (theoretical) framework. The existing knowledge was the source of reasoning leading to solve the scientific problem. It was rather implicit two-stage process of reasoning. The first stage was to reframe the conceptual framework, which was based on the analysis of the living lab concept seen from the perspective of the unique nature of social innovation and its limits. In the second stage, prototyping of a new concept of social innovation living lab was built on the conceptual framework developed at the first stage. Findings: The original theoretical model of social innovation living lab and its operationalization have been developed. It is based on the concept of living labs regarded as long term environments for open innovation that are being developed with real users in real contexts, and framed from the perspective of design-led approach to management and innovation. Value Added: The literature review has revealed the significant lack of research studies on the processes of generating social innovation. The proposed original model of social innovation living lab helps fill this gap. Social innovations as successful exploitation of new ideas to meet social problems and needs are essential in social and economic life. However, the conventional approaches to innovation are not sufficient to develop social innovation due to its nature. The proposed approach describes the operation of the social innovation living lab as an effective way to develop such innovations and at the same time the methodology useful in the further research. Recommendations: The proposed original approach to the processes of designing and accomplishing social innovation can help to develop such innovations in a more intentional and goal-oriented way, which is difficult using traditional laboratories due to the nature of such innovations.
Preliminary Validation of Mirrored Scales for Monitoring Professional Soccer Training Sessions

Abstract We aimed to create a single subjective method to assess both internal training loads and subsequent fatigue. This new training-fatigue (dose-response) scale (TFS) was composed of two similar scales with the same properties, metrics and construction criteria. These two scales were designed to rate the perceived exertion (RPETFS) and perceived fatigue (RPFTFS) in professional soccer players. Twenty-two athletes participated to establish reliability, and 15 participated to establish validity. For reliability, the intraclass correlation coefficient (ICC) and standard error of measurement (SEM) were used. For criterion validity, the Spearman’s correlation coefficient and linear regression analyses were applied. Associations between RPETFS and RPFTFS were verified by a chi square test, and a further factorial exploratory analysis was conducted. RPETFS and RPFTFS were found to be reliable (ICC 0.74 and 0.77, SEM 0.30 and 0.30, respectively) and valid. RPETFS was best explained by the internal load of the Banister training impulse (p < 0.001), while RPFTFS was best explained by the internal load of the Stagno training impulse (p < 0.001). An association was found between the scales (RPETFS and RPFTFS) in which training duration had a more substantial impact on these subjective perceptions than did training intensity (p < 0.01). RPETFS and RPFTFS scales are reliable and valid for monitoring training sessions in Brazilian professional soccer players. The simultaneous oscillations of the RPETFS and RPFTFS scores can be used by staff members to better plan weekly training programs based on dose-response ratings. Finally, training duration must be carefully controlled because it has a greater impact than intensity on subjective perceptions.
Association between arterial hypertension and chronic obstructive pulmonary disease: role of AGT gene polymorphism

Abstract Background Chronic obstructive pulmonary disease (COPD) continues to cause a heavy health and economic burden in the Europe and around the world. Arterial hypertension (AH) is considered as one of the principal COPD-associated comorbidi-ties. However, no data for association between gene polymorphism and AH in patients with COPD in Ukraine have ever been internationally published. We assessed the genotype and allele frequencies of angiotensinogen (AGT) M235T polymorphisms in patients with COPD and comorbid AH. Methods The study group consisted of 96 patients: Group 1 (25 individuals with COPD), Group 2 (23 individuals with AH) and Group 3 (28 individuals with COPD and AH). The control group consisted of 20 healthy subjects. M/T genotypes of AGT were determined by polymerase chain reaction amplification. Results The results of the study have not demonstrated any significant impact of alleles of AGT genes on the occurrence of diseases such as COPD, AH and combinations thereof. However, analysis of odds ratio has demonstrated the presence of a trend towards a protective role of the M allele of the AGT gene concerning occurrence of COPD, AH and their combinations. At the same time, the presence of the T allele of the AGT gene may increase the risk for occurrence of the above-mentioned diseases. Conclusions The study that we have conducted suggests that the presence of T allele of the AGT gene at position 235 of the peptide chain both in homozygous and heterozygous states may increase the risk for AH in patients with COPD.
Effects of metallurgical factors on reticular crack formations in Nb-bearing pipeline steel

Abstract Microscopic morphologies of reticular cracks in Nb-bearing pipeline surfaces are shown in this work. A decarburization layer, oxidized round spots, and the distributions of residual elements are each detected to better understand the mechanisms of reticular crack formations. The results show that reticular cracks are discontinuously distributed and filled with iron oxide. The oxidized round spots near the crack sides are larger and more intensive than steel matrix, with primary chemical compositions of Fe, Mn, and Si oxides. There is no obvious enrichment of Cu, Cr, or Sn near the crack zones. The formation of reticular cracks occurs prior to both decarburization and the formation of oxidized round spots. The ferrite potential (FP) of the examined pipeline steel is 1.05, which leads to a higher relative crack susceptibility. It is concluded that reticular cracks are generated during the continuous casting solidification process due to the extension of intergranular microcracks along grain boundaries under the abnormal conditions of the continuous casting process.
The Influence of Study Stream on Carrier Self-Efficacy among Secondary School Students

This article aims to measure the level of career self-efficacy among secondary school students. It determines whether the variable of career self-efficacy could be correlated to the variable of study streams. A total of 1060 respondents had been selected by systematic cluster random samplings from 106 national secondary schools in Terengganu. This survey used a set of questionnaires that consists of two parts: (i) Demographic information (ii) Career Self-efficacy that had been tested and has high levels of validity and reliability with alpha cronbach value was 0.95. The data obtained had been analyzed using descriptive analysis that included t-Test, mean, and standard deviation to meet the research objectives. The result showed that the level of students’ career self-efficacy is significantly different in accordance with their study streams. It could be concluded that the level of career self-efficacy among the students has been influenced by their study stream. Hence, any career guidance and counseling activities should consider the factor of study streams.
SOTICS 2014

—The limited availability of a valid speech corpus is one of the major problems affecting the design of speech recognition acoustic models. As a matter of fact, large amounts of manually-transcribed data is necessary in order to build a valid acoustic model. Nevertheless, obtaining large datasets is generally both time-and resource-consuming as it requires a continuous supervision of the entire building process. Speech corpora can be used to generate an acoustic model, however a large part of these are not suitable or freely available. This paper aims at showing the use of audiobooks as databases for creating speech corpora. An automatic algorithm that processes audiobooks for building speech corpora is proposed. This method allows to replace traditional manual transcription of audio-recordings and to automatically obtain a phonetic dictionary. An Italian acoustic and linguistic model was generated as use-case to test the effectiveness of the proposed procedure.
Assessment of Infant and Young Child Feeding Practices of Caregiver’s in Jashore City, Bangladesh

Since infant and young child feeding practices play an important role in ameliorating childhood nutrition, an exploratory and descriptive study has thus been conducted employing a previously developed questionnaire at Ad-din shisu Hospital, Jashore, Bangladesh to obtain better insights about the breastfeeding and complementary feeding practices among infant and young child feeding caregivers. Out of 260 babies, 54% were female and 46% were male. Nearly all caregivers were found having the idea that breast milk is the best food for newborn babies. Around 81.9% of caregivers think that breast milk contains all the nutrients the baby needs to flourish, but in case of protection from disease, only 18.1% of caregivers think that it protects the baby from certain diseases. Around 46.9% mothers practiced early initiation of breastfeeding and they offered breast milk to their newborn right away (within one hour) after delivery, 53.5% lactating mothers had proper knowledge about breastfeeding methods, 39.6% mothers never practiced burping after breastfeeding, 66.4% mothers had normal delivery, 33.6% mothers had caesarian section, 99% mothers offered colostrums to their babies and only 1% of them didn’t give the colostrums. Besides, 88.8% continued breastfeeding up to 24 months or more along with 83.8% caregivers starting complementary feeding from six months, 55.4% caregivers said baby’s immune system is less developed, so they get attacked by infection easily and 44.6% caregivers said “their tummies are vulnerable to infection”, and 48.8% of the caregivers followed the type of hygiene required. Our findings revealed information on the knowledge, attitude, and practices of the caregiver’s towards breastfeeding and complementary feeding.

Evaluation of the Longitudinal Dispersion Coefficient for Dor-Nwezor-Bodo River using Tracer Experiment and Theoretical Measurement

Natural water bodies such as creeks, Rivers, lakes, streams, and oceans can be protected from the impact of pollutants often discharged into it, through routine pollution warning and control services [1,2]. Dispersion studies are very significant tools that can support pollution warning and control for natural waters. In actual fact, polluted natural waters can regain its natural status after flowing over a given distance. The process of achieving this is called dispersion (or self-purification). Although it is a complex process, it can be achieved by a combination of physical, chemical and biological mechanisms that can occur simultaneously or stepwise. Typical mechanisms for pollutant dispersion include mixing, dilution, sedimentation, re-aeration, de-oxygenation, absorption, and adsorption. Others are chemical and biological digestion [3,4].
Meat Fatty Acid and Cholesterol Content of Native Indonesian Muscovy Duck Fed with Rice Bran in Traditional Farm

Fat, cholesterol and fatty acid profile of breast and thigh meat of 12 Muscovy ducks (6 drakes) aged 8 weeks from the local farm in Bogor, West Java were analyzed in thus study. In general, Muscovy ducks were fed with rice bran twice a day and free-ranged in the backyard. The nutrition of rice bran is varied in crude protein, crude fiber, fat, and ash content. Muscovy ducks were slaughtered and the percentage of carcass weight, fat, cholesterol and fatty acid profile of the breast and thigh meat were measured and analyzed. The result showed that the breast meat had higher (P<0.05) ω3 total fatty acid EPA (C20:5ω3) but DHA (C22:6ω3) and linolenic acid (C18:3ω3) were not significant compared to that of thigh meat. Concentration of linolenic acid in breast meat ranged from 0.26 to 0.51% of fat and 0.35 to 0.39% of fat in thigh meat. Linoleic acid (C18:2ω6) in breast and thigh meat was 7.64 - 10.73% and 5.17 - 13.93 % fat, respectively. DHA concentration ranged from 0.13-1.31% fat in breast meat and EPA in thigh meat was approximately 0.08-0.32 % fat. EPA was significantly higher (P<0.05) in breast meat (0.03-0.28 %) than thigh meat (0.05-0.08 %) The study produced ω 6:3 ratio ranged 6.50-24.14 and 8.94-31.64 in breast and thigh meat, respectively.
AMBIENT 2019 Proceedings

An automated monitoring of chronic diseases may help in the early identification of exacerbation, reduction of healthcare expenditure, as well as improve patient's healthrelated quality of life. Cough monitoring provides valuable information in the assessment of asthma and Chronic Obstructive Pulmonary Disease (COPD). In this multi-cohort study, we have used every-day wearables such as smartphone and smartwatch to collect cough instances from 131 subjects including 69 asthma patients, 9 COPD patients, 13 patients with a co-morbidity of asthma and COPD and 40 healthy controls. For online cough detection we have identified the audio features suitable for resource-constrained platforms (e.g., smartphone), ranked the features and identified top 9 features to obtain an F-1 score of 99.8% in the offline classification of 23,884 cough instances from non-cough (speech/silence, etc.) events using Random Forest classifier. Finally, a power and time-efficient scheme for continuous online cough detection from the audio stream has been illustrated. The proposed model has an online cough detection sensitivity of 93.3%, specificity of 98.8% and accuracy of 98.8%. In addition, a good improvement in reducing the on-device execution (feature extraction and classification) time and power consumption has been achieved compared to the current state of the art algorithms. The proposed on-device cough detector has been implemented to meet the criteria for integration in the passive monitoring and online assessment of asthma/COPD patients.

Determinants of Consumers' Perceived Experience Value in Relation to Online Organic Food Purchase

Organic food buying behavior is high involvement purchase and related to consumers' deeper value system. The decision-making is quiet complex due to its high price and lack of trustworthiness. Therefore, there is a need for separate and more engaging shopping platform, which can co-create a delightful and enjoyable shopping experience for the consumers. Literature does not give a clear understanding about the factors which can influence Consumers' Perceived Experience Value (CPEV). Hence the study aims to identify the drivers or the determinants of CPEV in relation to online organic food purchase. The objectives of this study are to identify the domain of constructs along with their respective items for CPEV and their relation through qualitative exploration and validate the items for respective construct through Exploratory and Confirmatory Factor Analysis. The study contributes a scale which can measure the constructs like Cognitive Engagement, Emotional Engagement, Behavioral Engagement, Telepresence, Willingness to co-create, Willingness to pay for Experience and Ease of Use in relation to online organic food purchase which was not available in the existing literature. This will be beneficial for the organic food producers to develop a digital marketing strategy and penetrate the market. The study will also help the service and experience designers to explore these opportunities and create a platform for the small-scale farmers and contribute in their livelihood development.
