Protecting H.264/AVC Data-Partitioned Video Streams over Broadband WiMAX

Broadband wireless technology, though aimed at video services, also poses a potential threat to video services, as wireless channels are prone to error bursts. In this paper, an adaptive, application-layer Forward Error Correction (FEC) scheme protects H.264/AVC data-partitioned video. Data partitioning is the division of a compressed video stream into partitions of differing decoding importance. The paper determines whether equal error protection (EEP) through FEC of all partition types or unequal error protection (UEP) of the more important partition type is preferable. The paper finds that, though UEP offers a small reduction in bitrate, if EEP is employed, there are significant gains (several dBs) in video quality. Overhead from using EEP rather than UEP was found to be around 1% of the overall bitrate. Given that data partitioning already reduces errors through packet size reduction and differentiation of coding data, EEP with data partitioning is a practical means of protecting user-based video streaming. The gain from employing EEP is shown to be higher quality video to the user, which will result in a greater take-up of video services. The results have implications for other forms of prioritized video streaming.
Culture and Internet Consumption: Contributions from Cross-Cultural Marketing and Advertising Research

Cross-cultural marketing and advertising research reveal important influences of culture on the global consumption of the Internet and its World Wide Web. The prevailing concepts of culture in this field of research—drawn mostly from the models of Geert Hofstede and Edward T. Hall—are discussed here with respect to their limitations and utility for the increasing number of Web-related contributions from marketing research. As a consequence, additional findings on cultural influences on Web site design, related structural design criteria, basic conditions, and complementary criteria for culturally appropriate websites are discussed that may impact the future of the Digital Divide.
Impact of Board of Supervisor Capital on Validity of Monitoring

The paper analyses the impact of the board of supervisors capital on validity of monitoring, which includes monitoring the company finance and the behavior of harming company benefit from directors and senior management based on resource independence theory and resource-based view. The members in board of supervisors have human capital or social capital that will reduce the harm behavior efficiently. Meanwhile increasing the width and depth in members of board of supervisors can strengthen validity of monitoring finance.
What does the brand say? Effects of brand feedback to negative eWOM on brand trust and purchase intentions

ABSTRACT This study examined the effects of brand feedback to negative electronic word of mouth (eWOM) on consumers’ brand trust and purchase intentions, and examined the moderating effect of problem attribution described in the negative eWOM message. Results from a 2 (Brand Feedback: Present/Absent) × 2 (Causal Attribution: Brand/Reviewer) × 2 (Products: Laptop/TV) between-subjects online experiment suggest that brand feedback had a simultaneous positive and negative effect on purchase intentions, whereby brand trust mediated the positive effect. Attribution of the product's problem did not significantly change this effect. Findings help to clarify the literature by describing mechanisms through which brand feedback occurs to influence brand outcomes.
Brand personality, brand loyalty and brand quality rating in the contact lens perspective

Contact lenses provide the best visual ergonomics after eye glasses. More than 5 million Malaysians wear some type of contact lenses and many of these individuals take into consideration the brand that is associated with the product. This paper seeks to determine the interrelationship between brand personality, brand loyalty and brand quality ratings in the contact lenses perspective. The measurement of brand personality was based on Aaker’s Brand Personality Scale, attitudinal and behavioural loyalties were used to measure brand loyalty and a scale was used to determine brand quality rating based on the work of Sethuraman and Cole. The primary data was gathered from 238 management students in a Malaysian public university using stratified random sampling method. The result indicated that the most important brand personality dimension associated with the contact lens was competence/modernity. It was found thatSincerity, Excitement, and Competence/Modernity of brand personality significantly affects brand loyalty. Competence/modernity and sincerity of brand personality were found to have significant effect on brand quality rating. The significant means differences were observed in the brand personality according to users, nonusers and users of other brands of the contact lens. Implication of the findings were highlighted and discussed based on the research findings.
Control System in an Utilitarian Organisation

PROCESS OF control is an inevitable correlate of any organisation. Hobbes suggested that man is essentially selfish and in order to 'control' his selfishness society is necessary. Every social unit has a structure and it controls its members, but organisations have a distinct structure, and their problem of control is especially acute one. Means of control distributed among various organisational positions can be exhaustively classified into three analytical categories: physical, material, and symbolic (Etzioni, 1965). The application of physical means for control purposes (as a gun) is referred to as coercive power. Material rewards consist of goods and services. The use of material means for control purposes is referred to as utilitarian power. Symbols (as prestige and esteem) whose use docs not constitute a physical threat or grant of rewards are pure symbols. -The use of these for control purposes is referred to as identitive power. The use of various kinds of means for control purposes-power, in short-has different consequences in terms of the nature of discipline elicited. As e"Kamples of organisations using various types of power system, it may be said that prison may be an example of coercive organisation using coercive power. Military organisations in democratic countries may serve as examples of identitive organisations using that type (identitive) of power. In such organisations, there tend to be few officials and few informal leaders: formal leaders effectively control most of organisational participants. Industrial organisations are considered utilitarian organisations. There, control is more evenly divided among organisational officials, formal leaders, and informal leaders of the employees. The main concern of these organisations is with instrumental control, i.e., with control of matters, such as production and efficiency and not with control of relations and norms established by the workers, so long as these do not adversely affect the instrumental activities. The particular leadership pattern (control style) that evolves, depends largely on the relative degree of alienation or commitment of the employees.
EARLY HEMATOPOIETIC EFFECTS OF CHRONIC RADIATION EXPOSURE IN HUMANS

The major goal of this study is to investigate and quantitatively describe the nature of the relationship between the characteristics of chronic exposure to ionizing radiation and specific patterns of hematopoiesis reduction. The study is based on about 3,200 hemograms taken for inhabitants of the Techa riverside villages over the years 1951–1956, i.e., the period characterized by a gradual decrease in dose rates. The mean cumulative red bone marrow dose was 333.6 ± 4.6 mGy. The approach to statistical analyses involved both empirical methods and modeling (generalized linear models and logistic regressions). The results of the analyses highlighted a gradual increase in the frequency of cytopenias with dose rate. The impact of exposure on hematopoiesis reduction patterns was found to be more substantial than that of age and health status. Dose rates resulting in a two-fold increase in the frequency of cytopenias have been estimated.
Double-Frequency Buck Converter

Improving the efficiency and dynamics of power converters is a concerned tradeoff in power electronics. The increase of switching frequency can improve the dynamics of power converters, but the efficiency may be degraded. A double-frequency (DF) buck converter is proposed to address this concern. This converter is comprised of two buck cells: one works at high frequency, and another works at low frequency. It operates in a way that current in the high-frequency switch is diverted through the low-frequency switch. Thus, the converter can operate at very high frequency without adding extra control circuits. Moreover, the switching loss of the converter remains small. The proposed converter exhibits improved steady state and transient responses with low switching loss. An ac small-signal model of the DF buck converter is also given to show that the dynamics of output voltage depends only on the high-frequency buck cell parameters, and is independent of the low-frequency buck cell parameters. Simulation and experimental results demonstrate that the proposed converter greatly improves the efficiency and exhibits nearly the same dynamics as the conventional high-frequency buck converter. Furthermore, the proposed topology can be extended to other dc-dc converters by the DF switch-inductor three-terminal network structure.
The Labour‐force Participation of the Wives of Unemployed Men: Comparing Britain and West Germany Using Longitudinal Data

When one partner in a couple becomes unemployed, one might suppose that the other partner will ¢nd a job to supplement the household income. However, previous research indicates the opposite of this ‘added worker’eiect in Britain, adding to rising concern about the growth of ‘workless’ households there. In this paper we test this ¢nding and investigate how it relates to welfare bene¢ts received by the unemployed, comparing two countries with diierent welfare systems, Britain and Germany. We compare the labour-force transitions of the wives of unemployed and employed men using discrete-time event-history modelling on the BHPS and GSOEP, in the ¢rst piece of work on this question which is both comparative and longitudinal.While we ¢nd some evidence of an addedworker eiect in Germany, our ¢ndings suggest a disincentive eiect of means-tested bene¢t on partners’ employment in Britain. These contrasting eiects are only found for women’s transitions from inactivity to employment; in both countries women who are already employed tend to remain so. Our ¢ndings suggest that the eiects of the bene¢t system on a partner’s employment should be considered in both the debates on comparative welfare regimes, and the discussion of workless households.
A public-key based watermarking for color image authentication

We present a watermarking scheme for color image authentication based on cryptography. The scheme shows that if even a single bit has been changed, the watermarked image is regarded as unauthentic. Moreover, the scheme indicates the specific locations where changes have been made. To increase the security, the scheme uses two keys for the permutation of the input of the hash function and for the encryption (decryption) of watermark bits during the watermark insertion and extraction procedures, respectively. Results show that our watermark is correctly extracted if there is no change of watermarked image. However, any change of a watermarked image results in no watermark. The pixel changes of the watermarked image are reflected in the extracted watermark, which indicates the attacked area.
Highly specific zinc finger proteins obtained by directed domain shuffling and cell-based selection

Engineered Cys2His2 zinc finger proteins (ZFPs) can mediate regulation of endogenous gene expression in mammalian cells. Ideally, all zinc fingers in an engineered multifinger protein should be optimized concurrently because cooperative and context-dependent contacts can affect DNA recognition. However, the simultaneous selection of key contacts in even three fingers from fully randomized libraries would require the consideration of >1024 possible combinations. To address this challenge, we have developed a novel strategy that utilizes directed domain shuffling and rapid cell-based selections. Unlike previously described methods, our strategy is amenable to scale-up and does not sacrifice combinatorial diversity. Using this approach, we have successfully isolated multifinger proteins with improved in vitro and in vivo function. Our results demonstrate that both DNA binding affinity and specificity are important for cellular function and also provide a general approach for optimizing multidomain proteins.
A Model of Textual Emotion Mining From Text Document

Mining social emotions from text and more documents are assigned by social users with emotion labels like happiness, warmness, and amusement. Documents categorized based on emotions and it help for related document selection in online. It can collect document from social users and assign emotion for the words in that document and based on the preference level we can achieve emotion for the whole document. In the existing approach usually the document model is the bag-of-word and there is no relationship between the words. In proposed work documents collected from online and using emotion-topic model for emotion modeling. It first generates topic from document followed by affective terms and effectively identify emotion for the topic. In online news collections show that the model is not only effective in extracting the meaningful latent topics, but also significantly improves the performance of social emotion prediction. KEYWORDS-affective text mining, emotion-term model
Des‐γ‐carboxyl prothrombin is associated with tumor angiogenesis in hepatocellular carcinoma

Background and Aim: Hepatocellular carcinoma (HCC) is a hypervascular tumor, and angiogenesis plays an important role in its development. Previously, we demonstrated that des‐γ‐carboxyl prothrombin (DCP) promotes both cell proliferation and migration of human umbilical vein endothelial cells (HUVECs) by inducing the autophosphorylation of kinase insert domain receptor (KDR). In the present study, DCP‐associated tumor angiogenesis was assessed by comparing hypovascular and common hypervascular HCC.
Stimulation of L-alanine-induced germination of Bacillus cereus spores by D-cycloserine and O-carbamyl-D-serine

Alanine racemase occurs in some bacterial spores (B. T. Stewart and H. 0. Halvorson, J. Bacteriol. 65:160, 1953). It can reduce the rate and amount of germination of spores in L-alanine by catalyzing production of D-alanine (G. Fey, G. W. Gould, and A. D. Hitchins, J. Gen. Microbiol. 35:229, 1964), an inhibitor of L-alanine-induced germination which presumably acts by inhibiting L-alanine dehydrogenase (R. J. O'Con-
High expression of hepatitis B virus based vector with reporter gene in hepatitis B virus infection system.

AIM To construct a hepatitis B virus (HBV)-based vector with a reporter gene and to establish an HBV infection system to evaluate the availability of the vector. METHODS The HBV-based vectors with green fluorescence protein (GFP) were packaged into the liver of immunodeficient mice through transfer and helper plasmid using hydrodynamic technology. Wild type HBV (wt HBV) was provided by plasmid MC2009. Primary human hepatocytes (PHH) were isolated and infected with recombinant HBV (rHBV) or wt HBV. GFP expression was monitored by confocal and flow cytometry. HBV DNA and HBV surface antigen (HBSAg) were analyzed by PCR and ELISA. RESULTS 3 x 10(7) wt HBV copies/mL and 5 x 10(6) rHBV copies/mL were collected from mice serum. In the wt HBV infected group, HBV progeny was 2 x 10(7) copies/mL and HBSAg was 770 ng/mL. In the rHBV infected group, GFP fluorescence was detected on d 3 post-infection and over 85% of the parenchymal cells expressed green fluorescence on d 12 post-infection. Compared with wt HBV in the PHH infection system, no rHBV DNA or HBSAg were detected in PHH culture media. CONCLUSION An effective HBV based vector was developed, which proved to be a useful HBV infection system. This vector and infection system can be applied to develop a therapeutic vector and study the HBV life cycle and viral pathogenesis.
Low complexity digital IQ imbalance correction in OFDM WLAN receivers

This work proposes a time-domain scheme for digital correction of IQ imbalance in OFDM WLAN receivers, according to IEEE 802.11a/g. Recently, the zero-IF architecture became an attractive candidate for inexpensive OFDM WLAN receivers. It avoids costly components but introduces IQ imbalance. Since OFDM, using higher order modulation, is very sensitive to non-idealities in the receiver front-end, we developed a new very low complexity scheme to estimate and correct IQ imbalance. The scheme is based on one time-domain OFDM long preamble symbol and performs excellent in AWGN conditions, even for high levels of IQ imbalance. For multipath fading conditions, acceptable performance is demonstrated. Due to its very low complexity, our new scheme offers high feasibility, and therefore, helps to greatly relax front-end requirements and to enable low-cost OFDM WLAN receivers.
Enhancing EBP Skills of RN‐BSN Students Through Academic Mentoring in Independent Study

INTRODUCTION AND BACKGROUND The number of hospitals seeking recognition for nursing excellence through the American Nurses Credentialing Center (ANCC) Magnet Recognition Program continues to expand (American Nurses Association, 2017; Granger et al., 2012). Organizations aspiring to Magnet status must support the advancement of nursing, evidenced through research and evidence-based practice (EBP) projects (ANCC, 2017). Data suggest clinical nurses may lack the knowledge needed for EBP and rely heavily on personal experience, rather than searching for the latest evidence to support clinical decision making (Yoder et al., 2014). Furthermore, 90% of baccalaureate level students overestimate their ability to locate and appraise the online health literature, a skill fundamental to the utilization of EBP (Ivanitskaya, Hanisko, Garrison, Janson, & Vibbert, 2012). Little consideration has been given in the peer-reviewed literature to the role of academic faculty mentoring of RN-BSN students returning to school for degree completion via independent studies (IS) as a means of enhancing EBP research competencies. The purpose of this column is to discuss the tactic and outcomes of an IS designed to increase online research and EBP proficiency.
Using Intrinsic Integer Periodicity to Decompose the Volterra Structure in Multi-Channel RF Transmitters

An instrumentation, measurement and post-processing technique is presented to characterize transmitters by multiple input multiple output (MIMO) Volterra series. The MIMO Volterra series is decomposed as the sum of nonlinear single-variable self-kernels and a multi-variable cross-kernel. These kernels are identified by sample averages of the outputs using inputs of different sample periodicity. This technique is used to study the HW effects in a RF MIMO transmitter composed by input and output coupling filters (cross-talk) sandwiching a non-linear amplification stage. The proposed technique has shown to be useful in identifying the dominant effects in the transmitter structure and it can be used to design behavioral models and compensation techniques.
Improving Usability of e-Government for the Elderly

: Our research focuses on the question of acceptance of current e-government systems by elderly users. It describes how such systems should be designed and offered for this user group in order to provide an acceptable alternative to offline processes. In order to answer our research question, the research was structured into three phases along the development model of the ISO 9241-210. This enabled to identify not only the main factors of acceptance, but also the expectations of elderly users. Our research was conducted in parallel in Germany and Hungary in cooperation with the Fraunhofer FOKUS, the Federal Ministry of Interior, the Bundesdruckerei and the Corvinus University Budapest. The first phase provided results about the expectations and previous experience of the users with e-government systems. Our goal was to acquire information about the general experience of the age group with interactive applications so that a suitable test environment could be selected in the second phase of the research. The results made it possible to select an application in the second phase, which was used as a model in the remaining phases. The selected application was the AusweisApp of the electronic ID card. This was tested with 75 participants and a control group consisting of 20 students of the Humboldt-University. The obtain results allowed us to develop a generalised solution, the IGUAN guideline. This guideline makes a standardised approach to the usability improvement process possible. It contains the special requirements of elderly users, and a catalogue of criteria, which helps to develop an application in line with the set requirements. The third phase of our research was used a proof of concept for the IGUAN. The guideline was evaluated and tested with an iterative prototyping. The successful completion of this phase indicates that the IGUAN can be used to measurably increase the acceptance of e-government systems by elderly users. We could therefore demonstrate that improvements in the interface make e-government application possible which are perceived useful and easy to use by elderly users. These improvements will measurably increase the user motivation and experience. This can however only be achieved with a structured design process, and requires a framework which takes the requirements of the elderly users into account.
