The Influence of Beauty-Related YouTube content on Consumers' Purchase Intention

With the development of the internet, electronic word of mouth (eWOM) has been considered a significantly effective tool to appeal to consumers. Many previous studies have investigated eWOM, but most of them focused on textual eWOM. Thus, this study examines eWOM in the context of beauty-related videos on YouTube. The Information Adoption Model is used to test whether those videos influence cosmetics purchase intention of consumers. This study conducted an online survey of 427 female millennials. The collected data was analyzed by Partial Least Square (PLS) regression. The results confirmed that information quality and source credibility were the important determinants of perceived information usefulness which significantly and positively influenced information adoption and purchase intention. Moreover, this study also supported the extended vision about the relationship between information quality and source credibility in the context of the elaboration likelihood model (ELM). Based on the results, theoretical and practical implications are highlighted.
Anti-Inflammatory Activity of the Essential Oil Citral in Experimental Infection with Staphylococcus aureus in a Model Air Pouch

This study proposes to implement an alternative and effective strategy for local treatment of disease provoked by S. aureus. For the analysis of possible anti-inflammatory activity of essential oil, after establishing an air pouch model, 48 male mice of Balb/c were treated, infected, and euthanized at 4 and 8 h. Thus, the total and differential white blood cells were counted in the animal's blood, and cytokines IL-1β, IL-6, and TNF-α were titrated using ELISA in the air pouch lavage. Moreover, TNF-α, IL-1β, and IL-6 gene expression was analyzed through an RT-qPCR array, and S. aureus was quantified using qPCR. Our results, p < 0.05, showed that EOC reduced the quantity of microorganisms. The group of mice treated with essential oil citral showed a significant decrease in TNF-α levels in tests demonstrating anti-inflammatory activity. There is no data about the mutual influence of the air pouch model, essential oil citral, and S. aureus. Thus, considering the interaction of these variables and the anti-inflammatory activity of the essential oil citral, we demonstrated, by alternative local treatment, a new antimicrobial agent that is not an antibiotic.
Tertiary Lymphoid Structures in Cancers: Prognostic Value, Regulation, and Manipulation for Therapeutic Intervention

Tertiary lymphoid structures (TLS) are ectopic lymphoid aggregates that reflect lymphoid neogenesis occurring in tissues at sites of inflammation. They are detected in tumors where they orchestrate local and systemic anti-tumor responses. A correlation has been found between high densities of TLS and prolonged patient’s survival in more than 10 different types of cancer. TLS can be regulated by the same set of chemokines and cytokines that orchestrate lymphoid organogenesis and by regulatory T cells. Thus, TLS offer a series of putative new targets that could be used to develop therapies aiming to increase the anti-tumor immune response.
Microbial diversity and community structure across environmental gradients in Bransfield Strait, Western Antarctic Peninsula

The Southern Ocean is currently subject to intense investigations, mainly related to its importance for global biogeochemical cycles and its alarming rate of warming in response to climate change. Microbes play an essential role in the functioning of this ecosystem and are the main drivers of the biogeochemical cycling of elements. Yet, the diversity and abundance of microorganisms in this system remain poorly studied, in particular with regards to changes along environmental gradients. Here, we used amplicon sequencing of 16S rRNA gene tags using primers covering both Bacteria and Archaea to assess the composition and diversity of the microbial communities from four sampling depths (surface, the maximum and minimum of the oxygen concentration, and near the seafloor) at 10 oceanographic stations located in Bransfield Strait [northwest of the Antarctic Peninsula (AP)] and near the sea ice edge (north of the AP). Samples collected near the seafloor and at the oxygen minimum exhibited a higher diversity than those from the surface and oxygen maximum for both bacterial and archaeal communities. The main taxonomic groups identified below 100 m were Thaumarchaeota, Euryarchaeota and Proteobacteria (Gamma-, Delta-, Beta-, and Alphaproteobacteria), whereas in the mixed layer above 100 m Bacteroidetes and Proteobacteria (mainly Alpha- and Gammaproteobacteria) were found to be dominant. A combination of environmental factors seems to influence the microbial community composition. Our results help to understand how the dynamic seascape of the Southern Ocean shapes the microbial community composition and set a baseline for upcoming studies to evaluate the response of this ecosystem to future changes.
Turning Internet of Things(IoT) into Internet of Vulnerabilities (IoV) : IoT Botnets

Internet of Things (IoT) is the next big evolutionary step in the world of internet. The main intention behind the IoT is to enable safer living and risk mitigation on different levels of life. With the advent of IoT botnets, the view towards IoT devices has changed from enabler of enhanced living into Internet of vulnerabilities for cyber criminals. IoT botnets has exposed two different glaring issues, 1) A large number of IoT devices are accessible over public Internet. 2) Security (if considered at all) is often an afterthought in the architecture of many wide spread IoT devices. In this article, we briefly outline the anatomy of the IoT botnets and their basic mode of operations. Some of the major DDoS incidents using IoT botnets in recent times along with the corresponding exploited vulnerabilities will be discussed. We also provide remedies and recommendations to mitigate IoT related cyber risks and briefly illustrate the importance of cyber insurance in the modern connected world.
Estimation Bias in Maximum Entropy Models

Maximum entropy models have become popular statistical models in neuroscience and other areas in biology and can be useful tools for obtaining estimates of mutual information in biological systems. However, maximum entropy models fit to small data sets can be subject to sampling bias; i.e., the true entropy of the data can be severely underestimated. Here, we study the sampling properties of estimates of the entropy obtained from maximum entropy models. We focus on pairwise binary models, which are used extensively to model neural population activity. We show that if the data is well described by a pairwise model, the bias is equal to the number of parameters divided by twice the number of observations. If, however, the higher order correlations in the data deviate from those predicted by the model, the bias can be larger. Using a phenomenological model of neural population recordings, we find that this additional bias is highest for small firing probabilities, strong correlations and large population sizes—for the parameters we tested, a factor of about four higher. We derive guidelines for how long a neurophysiological experiment needs to be in order to ensure that the bias is less than a specified criterion. Finally, we show how a modified plug-in estimate of the entropy can be used for bias correction.
The Older Worker: Identifying a Critical Research Agenda

The roles that older workers play in labour markets has received a great deal of policy and academic scrutiny in response to economic crises and demographic change. As a starting point, this focus has paradoxically resulted in insufficient attention to older workers themselves. The article is thus concerned with refocusing the agenda for research onto the older worker. Building on an extensive literature review, four gaps in knowledge are identified: who might be researched; what the focus of that research might be; the role of theory informing the research; and how the research might be conducted. The article identifies a particular need for research on ‘work’ as opposed to ‘retirement’ and how the changing nature of work may influence future patterns of later life labour market engagement and retirement. It is argued that better public policy will result from more critical and socially embedded research that recognises the heterogeneity of ‘older workers’ and their motivations.
Absenceofthea £ atoxin biosynthesis gene , norA , allows accumulationofdeoxya £ atoxinB 1 inAspergillus £ avus cultures

Biosynthesis of the highly toxic and carcinogenic aflatoxins in select Aspergillus species from the common intermediate O-methylsterigmatocystin has been postulated to require only the cytochrome P450 monooxygenase, OrdA (AflQ). We now provide evidence that the aryl alcohol dehydrogenase NorA (AflE) encoded by the aflatoxin biosynthetic gene cluster in Aspergillus flavus affects the accumulation of aflatoxins in the final steps of aflatoxin biosynthesis. Mutants with inactive norA produced reduced quantities of aflatoxin B1 (AFB1), but elevated quantities of a new metabolite, deoxyAFB1. To explain this result, we suggest that, in the absence of NorA, the AFB1 reduction product, aflatoxicol, is produced and is readily dehydrated to deoxyAFB1 in the acidic medium, enabling us to observe this otherwise minor toxin produced in wild-type A. flavus.
Improving Security for Smart Grid with Multilayer Consensus ECC based PAKE Protocol ( SGMCEP )

The paper aims in providing a securely communicating of data between the devices which are nothing but appliance of Home Area Network (HAN) by a set of controller outside the HAN. The packets generated by the controller should be delivered fast without any interruption. The role of an HAN controller is like a gateway, whose role is to filter the incoming packet. Due to this HAN controller, the data in the packets should not be modified & it should not cause any delay in encryption & decryption of the packets. Based on the level of security and quality of service, we design the protocol with an Elliptic Curve Cryptography (ECC) approach. Password Authenticated Key Exchange (PAKE) protocol is improved & implemented. This consists of two phases. We propose an ECC version of PAKE & later extend this protocol to a multilayer consensus ECC based Password Authenticated Key Exchange (PAKE) protocol for smart grid. This protocol uses only one hash function & it utilizes a primitive password between the appliance and HAN controller. The four layer individual consensus password-authenticated symmetric key established between the appliance and upstream controllers during only 12 packets.It provides high security level with small key size when compared to RSA algorithm key size which is big with comparison to our proposed protocol. Proposed protocol is resistant against many attacks. It improves & reduces the delay caused by the security process by more than one half. Finally we show that our approach decreases the number of packets & improves the security in smart grid. Key words— Access control, BAN, Consensus, ECC, HAN, NAN, PAKE, Security, Smart grid.
Family Firm Research: The Need for a Methodological Rethink

The scale of family company activity in the United Kingdom was measured with regard to several family firm definitions. This study confirms that family companies are a numerically important group of businesses. Policy makers and practitioners must, however, be aware that the scale of family firm activity in any developed economy is highly sensitive to the family firm definition selected. Within a bivariate as well as multivariate statistical framework, marked demographic differences were identified between family and non-family companies with regard to several family firm definitions. We suggest that bivariate studies comparing the management practices and performance of family and non-family firms may have identified ‘demographic sample’ differences rather than ‘real’ differences. Implications for future research exploring the management and performance of family and non-family firms are discussed.
Human Neural Precursor Cells Express Low Levels of Telomerase in Vitro and Show Diminishing Cell Proliferation with Extensive Axonal Outgrowth following Transplantation

Worldwideattention is presently focused on proliferating populations of neural precursor cells as an in vitro source of tissue for neural transplantation and brain repair. However, successful neuroreconstruction is contingent upon their capacity to integrate within the host CNS and the absence of tumorigenesis. Here we show that human neural precursor cells express very low levels of telomerase at early passages (less than 20 population doublings), but that this decreases to undetectable levels at later passages. In contrast, rodent neural precursors express high levels of telomerase at both early and late passages. The human neural precursors also have telomeres (approximately 12 kbp) significantly shorter than those of their rodent counterparts (approximately 40 kbp). Human neural precursors were then expanded 100-fold prior to intrastriatal transplantation in a rodent model of Parkinson's disease. To establish the effects of implanted cell number on survival and integration, precursors were transplanted at either 200,000, 1 million, or 2 million cells per animal. Interestingly, the smaller transplants were more likely to extend neuronal fibers and less likely to provoke immune rejection than the largest transplants in this xenograft model. Cellular proliferation continued immediately post-transplantation, but by 20 weeks there were virtually no dividing cells within any of the grafts. In contrast, fiber outgrowth increased gradually over time and often occupied the entire striatum at 20 weeks postgrafting. Transient expression of tyrosine hydroxylase-positive cells within the grafts was found in some animals, but this was not sustained at 20 weeks and had no functional effects. For Parkinson's disease, the principal aim now is to induce the dopaminergic phenotype in these cells prior to transplantation. However, given the relative safety profile for these human cells and their capacity to extend fibers into the adult rodent brain, they may provide the ideal basis for the repair of other lesions of the CNS where extensive axonal outgrowth is required.
Prevalence of Urinary Tract Infection among Patients with Diabetes in Bangalore City

Urinary tract infections (UTI) are common in diabetic patients. The propensity of the infection can vary in different individuals especially when there is underreporting from the patients having a risk of acquiring infections. This investigation was based to evaluate the incidence of UTI in patients with DM. Between July 2005 - 2009, 1000 diabetic and non diabetic urine samples were collected. All urine samples were processed in the lab following standard laboratory protocol. Prevalence of UTI in the lower socioeconomic status was 56.4% and 43.6%. UTI in higher socioeconomic status was 51.6% and 48.4% . Commonly recovered UTI isolates were E.coli, Enterococcus faecalis, Pseudomonas aeruginosa, and Staphylococcus aureus. UTI was alarming in diabetic patients belonging to the lower socioeconomic status. In type 1 diabetic patients E.coli (44%) was the most prevalent cause of UTI. Varieties of factors are responsible for UTI in diabetic patients which include genetic susceptibility, and damaged immune response. The purpose of this study was to evaluate the prevalence of UTI among the diabetic patients and compare them with those of non diabetic ones from the areas of lower socio economic groups and higher socioeconomic group.
Performance Evaluation of Different Modulation Coding for Scheduling Services over VoIP in WIMAX Networks

WiMAX is a high speed, wireless broadband access technology (including high speed internet and multimedia access) for large coverage area. It presents IP contacting between the base station and subscribers. Voice over Internet Protocol (VoIP) through WiMAX is the most important in telecommunication service. In this paper, simulative discussion for VoIP in WiMAX network have been done considering the effect of Modulation Coding (MC) mechanisms on the Quality of Service(QoS) performance of scheduling types such as; UGS, rtPS, and ertPS using opnet simulator. The discussion have been done in terms of important QoS parameters like jitter, packet end to end delay and average throughput. The obtained results show that the best type of the MCs that would be enhanced the QoS performance of the WiMAX network is QPSK model with coding rate 1/2.
Critical Variables In Mathematics Education

Throughout the book it is shown how fundamentally simple ideas are capable of extension to become more difficult topics, e.g. the study of symmetry, so it is logical that the book ends with a look at "the way ahead". Links are suggested for the 9-11 year olds and for extending these links into the secondary schools for a modern geometry programme in which the primary children will have received a solid foundation. The book is presented as "a compendium of fully worked out suggestions for the use of schools. " and to my mind there is no doubt that these practical suggestions have been tried and proved. There is in this book an exciting originality, comprising quite fresh ideas as well as unexpected twists to more familiar ones, which, while serving as a refresher to the mathematics specialist in the primary school, must take its place as a refreshing and invaluable source book for the rest of us. There should be a copy in every primary classroom.
Output controller for quadcopters with wind disturbance cancellation

In the paper an output control approach for a class of nonlinear MIMO systems is presented. A multicopter with four symmetrical rotors, i.e. a quadcopter, is chosen to illustrate proposed adaptive control approach based on the high-gain principle, so-called, “consecutive compensator”. Output controller is designed by decomposition of the mathematical model on two parts. The first one is a static MIMO transformation (more precisely, in the considering case a system of linear equations which relates control signals for actuators and virtual control inputs). The second one is a few SISO channels. Such trick allows to design a control law in two steps. At the first step we design virtual controls for each SISO channel. Here we apply the mentioned systematic approach “consecutive compensator”, which also allows to cancel unknown wind disturbances changing their values and directions negligibly slowly. Then after the inverse MIMO transformation we get control signals for actuators.
Inhaled corticosteroids and the risk of a first exacerbation in COPD patients

The role of inhaled corticosteroids (ICS) in asthma is well established, but their benefit in the management of chronic obstructive pulmonary disease (COPD) is still controversial. The current study assessed whether ICS are effective in preventing a first exacerbation of COPD. A cohort of newly treated COPD patients was formed from the Administrative Databases of Saskatchewan Health. The outcome was the occurrence of a first moderate or severe exacerbation from 1990–1999. Moderate exacerbations involved prescriptions for an antibiotic and an oral corticosteroid on the same day. Severe exacerbations were hospitalisations with a primary discharge diagnosis of COPD. A nested case-control design was used and matched on year of birth and cohort entry. Rate ratios (RR) were further adjusted for use of other medication and other confounders. There were 995 exacerbations among 4,455 subjects. The rate of a first exacerbation was increased with any use of ICS in the year prior to the index date (RR: 1.27; 95% CI: 1.08–1.48) and with current use (RR: 1.51; 95% CI: 1.22–1.87), and it increased with increasing daily doses of ICS. Inhaled corticosteroids do not seem to be beneficial in reducing the risk of a first exacerbation of chronic obstructive pulmonary disease.
Effective teacher leadership : a quantitative study of the relationship between school structures and effective teacher leaders

The purpose of this quantitative study was to inves tigate the relationship between certain types of school structures and the effectiv ness of teacher leaders. The study focused on teachers who lead from within their clas srooms, as opposed to those who have left the classroom to take on different responsibil ities. The types of school structures investigated were determined through an analysis of nine previously conducted qualitative studies. Through this analysis, specifi c structural components in three categories: (a) role clarity, (b) physical structur es, and (c) organizational structures were identified. The structural components identified through analys is of these qualitative studies were utilized to develop the SSTLQ (School Structur es and Teacher Leadership Questionnaire). The questionnaire was completed by 158 teachers from various grade ranges who were enrolled in a professional developm ent program for teacher leaders in a Midwestern state. Data from the survey was analyzed using the Pearson correlation coefficient to determine the relationship between specific school structures and teacher leader effectiveness, as measured by the teacher leader’s impact on instructional change and student achievement. A forward multiple regression analysis was also utilized to
Nationwide Branch Banking and the Presence of Large Banks in Rural Areas

Relaxation of government restrictions on multi- office banking (interstate banking and branching by banks) in recent years has facilitated substantial consolidation of the banking industry in the United States. In this article, R. Alton Gilbert examines the impact of this consolidation on the presence of large banking organizations in rural banking markets. Changes in the presence of large banking organizations in rural areas depend on the history of state regulation of multioffice banking. In the states that have permitted statewide branching for many years, large organizations have had offices in most of the rural counties and accounted for large shares of local deposits in most of the rural counties since at least 1980. ; In contrast, the presence of large banking organizations in rural counties has increased substantially in recent years-in the states that relaxed their regulations of multioffice banking more recently-becoming more like those states that relaxed their regulation of multioffice banking many years ago. In almost all of the rural counties in the nation, however, relatively small banking organizations continue to hold large shares of local deposits. The evidence about the presence of large banking organizations in rural areas consistently supports the view that relatively small banks will continue to be major banking organizations in rural areas.
Studying the Relationships between Spatial Structures of Wireless Networks and Population Densities

In this paper we show how to quantify dependency between the node distributions of wireless networks and the underlying population densities. Furthermore, we show that a quantitative analysis of this relation can be beneficial for understanding and generating realistic network models. Towards this direction we argue that spatial statistics is an appropriate method for this purpose. As a case study we analyze the correlations of GSM-900 and UMTS base stations, with the underlying population densities of Germany. We find that there is a significant statistical similarity between the locations of GSM-900 base stations and population, due to the immense penetration of the network, and a less tight relation in the case of UMTS network. We consider the problem of covering a given population pattern and use the concept of fractal dimension to show how the number of required base stations changes when their maximum coverage range decreases, according to the population pattern.
