An Empirical Study on the Influencing Factors of Intention to Adoption of Mobile Government Service

Mobile technology is accelerating innovative changes across all fields of our society as well as business environments. Especially, demands on mobile government (M-government) services have been increased gradually since e-government has improved national administration services dramatically. However, high-quality services which are acceptable to may users are not actually supplied because technical issues such as security on mobile e-government services have not solved and governance policy was not established yet. Previous studies show that most researches are devoted to technical ones or limited to theoretical exploratory study. As a result, developing useful guidelines which are practically and theoretically proved is one of the very important research issues. This study reviews the previous research works such as concept of mobile, e-government, M-government, technical trends of mobile, market situations, present status, and various case studies. And then we develop a research model with five factors, twenty four variables and seventy six measurement for measuring the influencing factors to adoption of M-government services. The model is composed of total 16 hypotheses, 22 variables, and 76 measurements. The model is analyzed by usi ng statistical package SPSS (18.0) and AMOS (18.0) together with structural equation method based on 294 samples. The results show that the model is valid and there are statistically significant influence between ease of use and usefulness, ease of use and user’s satisfactions, usefulness and intent of re-use, and user’s satisfactions and intent of re-use, excepting usefulness and user’s satisfaction, ease of use and intent of re-use did not affect significant influences. Especially, service quality, system quality, and relationship quality are identified as influencing factors to adaption of M-government service. The results are expected to provide a theoretical research framework which generate new research issues in M-government service area. It also can provide an useful guidelines to practical experts in successfully implementing M-government services. Further research directions are as follows.
Responses of dairy cows to alternating electrical current administered semirandomly in a nonavoidance environment.

Eight Holstein cows were assigned to two groups of four each, and a switchback design was used. Treatments were 4 mA of alternating current and no current. Four periods were each 96 h. Current was applied across subdermal electrodes, located on each cow's spine for 30 s, with a 30-s rest period between exposures for 5 min. Cows received current every 4 h for four 24-h intervals. No individual cow received current at the same time every day. Milk yield was reduced . 16 kg/milking by exposure to 4 mA current. This decrease was not statistically significant. Percent milk fat and milk protein were not changed by current. Overall numbers of milk somatic cells were variable during the experiment. They increased during exposure to current, yet the increase was not statistically significant. Overall mean feed consumption and water consumption were not affected by treatments. The greatest behavioral response to current was upon initial exposure. Cows became accustomed to shock within 24 h of exposure. By the end of the fourth 96-h period of exposure, behavioral responses to current were almost extinct. We conclude that exposing cows to 4 mA of alternating current, in a semirandomized nonavoidance environment, for four consecutive 24-h intervals does not alter milk yield, milk composition, or intake of feed and water.
Reaction null-space based control of under-actuated manipulators

A general framework for under-actuated manipulator systems is introduced. Within this framework, we show how to decompose the second-order dynamic motion constraint into two orthogonal components. Based on this decomposition, feedback control laws are proposed for motion stabilization to a reactionless-motion equilibrium manifold. Reactionless motion without drift is guaranteed for first-order nonholonomic systems. It is also shown that for a second-order nonholonomic system, reactionless motion in general leads to a drift.
Assessment of a Campus Recreation Program on Student Recruitment, Retention, and Frequency of Participation across Certain Demographic Variables

The purpose of this study was to assess the impact of campus recreational sports facilities and programs on student recruitment and retention and to provide analysis regarding the number of times students participate in recreational sports activity. A convenience sample of students from classes in the Department of Physical Education and Health at a small southeastern university was used in the study. The instrument consisted of a modified version of the National Intramural-Recreational Sport Association's Quality and Importance of Recreational Services Survey. The chi-square test of homogeneity was used to test for differences, alpha = . 05. Significant differences were found on the gender and class standing variables studied. Although limitations of the study exist, the results provide further evidence that students report that the availability of recreational sports facilities and programs has an impact on both their decisions to attend and remain at an institution. Furthermore, the study shows that differences exist across gender and class standing variables in frequency of participation, a finding that can only serve to increase the practitioner's understanding of those who use such facilities and programs.
When to Make Telephone Interviews

A number of authors writing in the area of research methods have indicated the growing importance of telephone surveys [1, 3]. The increased number of households having a telephone and deeper penetration into rural and low-income areas have greatly improved the statistical efficiency of random samples drawn from the telephone directory. Also, the range of subject matter and length of the telephone interview are not as limited as generally believed [4]. In addition, evidence indicates that a respondent is more likely to be candid when the interview situation is impersonal [2], and the telephone does allow a significant degree of anonymity. When comparing the cost per return among mail, personal, and telephone surveys, the latter is considered far cheaper than personal interviews and often less costly than mail surveys [6]. In conducting telephone surveys, the time of day and day of week most likely to yield completed first calls must be identified in order to avoid time-consuming and costly callbacks [5]. This study was undertaken to determine the most fruitful days of the week and time of day to complete telephone interviews with housewives or female heads of households.
A mutation in the interferon-gamma-receptor gene and susceptibility to mycobacterial infection.

BACKGROUND Genetic differences in immune responses may affect susceptibility to mycobacterial infection, but no specific genes have been implicated in humans. We studied four children who had an unexplained genetic susceptibility to mycobacterial infection and who appeared to have inherited the same recessive mutation from a common ancestor. METHODS We used microsatellite analysis, immunofluorescence studies, and sequence analysis to study the affected patients, unaffected family members, and normal controls. RESULTS A genome search using microsatellite markers identified a region on chromosome 6q in which the affected children were all homozygous for eight markers. The gene for interferon-gamma receptor 1 maps to this region. Immunofluorescence studies showed that the receptor was absent on leukocytes from the affected children. Sequence analysis of complementary DNA for the gene for interferon-gamma receptor 1 revealed a point mutation at nucleotide 395 that introduces a stop codon and results in a truncated protein that lacks the transmembrane and cytoplasmic domains. CONCLUSIONS Four children with severe mycobacterial infections had a mutation in the gene for interferon-gamma receptor 1 that leads to the absence of receptors on cell surfaces and a functional defect in the up-regulation of tumor necrosis factor alpha by macrophages in response to interferon-gamma. The interferon-gamma pathway is important in the response to intracellular pathogens such as mycobacteria.
Muscarinic cholinergic receptors in the songbird and quail brain: A quantitative autoradiographic study

In order to clarify the neuroanatomical basis for postulated muscarinic cholinergic control of a wide array of physiological processes in birds, the distribution of muscarinic cholinergic receptors in the brain of three avian species was investigated by quantitative autoradiography. The species consisted of two passerines (songbirds), the European starling (Sturnus vulgaris) and the song sparrow (Melospiza melodia), and one galliform, the Japanese quail (Coturnix coturnix japonica). [3H] N‐methyl scopolamine (NMS), a muscarinic cholinergic antagonist was used as the ligand to label the receptors. Initial experiments demonstrated that the binding of this ligand in the three species is saturable in the nanomolar range and has a high affinity (Kd = ±0.6 nM). Displacement experiments revealed that three muscarinic ligands competed ii an order of potency characteristic of the mammalian muscarinic receptor (i.e., atropine ≥ oxotremorine ≥ carbachol) for NMS binding in the avian brain.
Pharmacodynamic Model To Describe the Concentration-Dependent Selection of Cefotaxime-Resistant Escherichia coli

ABSTRACT Antibiotic dosing regimens may vary in their capacity to select mutants. Our hypothesis was that selection of a more resistant bacterial subpopulation would increase with the time within a selective window (SW), i.e., when drug concentrations fall between the MICs of two strains. An in vitro kinetic model was used to study the selection of two Escherichia coli strains with different susceptibilities to cefotaxime. The bacterial mixtures were exposed to cefotaxime for 24 h and SWs of 1, 2, 4, 8, and 12 h. A mathematical model was developed that described the selection of preexisting and newborn mutants and the post-MIC effect (PME) as functions of pharmacokinetic parameters. Our main conclusions were as follows: (i) the selection between preexisting mutants increased with the time within the SW; (ii) the emergence and selection of newborn mutants increased with the time within the SW (with a short time, only 4% of the preexisting mutants were replaced by newborn mutants, compared to the longest times, where 100% were replaced); and (iii) PME increased with the area under the concentration-time curve (AUC) and was slightly more pronounced with a long elimination half-life (T1/2) than with a short T1/2 situation, when AUC is fixed. We showed that, in a dynamic competition between strains with different levels of resistance, the appearance of newborn high-level resistant mutants from the parental strains and the PME can strongly affect the outcome of the selection and that pharmacodynamic models can be used to predict the outcome of resistance development.
Predictive value of p16/Ki-67 immunocytochemistry for triage of women with abnormal Papanicolaou test in cervical cancer screening: a systematic review and meta-analysis

BACKGROUND The Papanicolaou (Pap) test is one screening strategy used to prevent cervical cancer in developed countries. The p16/Ki-67 immunocytochemistry is a triage test performed on Pap smears in women with atypical squamous cells of undetermined significance (ASCUS) or low grade squamous intraepithelial lesion. OBJECTIVE Our objective was to review studies investigating the diagnostic performance of p16/Ki-67 dual stain for triage of women with abnormal Pap tests. DESIGN We conducted a systematic review and meta-analysis of diagnostic test accuracy studies. SETTINGS We followed the protocol of systematic review of diagnostic accuracy studies. PATIENTS AND METHODS We searched PubMed, The Cochrane Library, BioMed Central, and ClinicalTrials.gov for relevant studies. We included research that assessed the accuracy of p16/Ki-67 dual stain and high risk human papillomavirus testing for triage of abnormal Pap smears. Review articles and studies that provided insufficient data to construct 2×2 tables were excluded. Data synthesis was conducted using a random-effects model. MAIN OUTCOME MEASURES Sensitivity and specificity. RESULTS In seven studies encompassing 2628 patients, the pooled sensitivity and specificity of p16/Ki-67 for triage of abnormal Pap smear results were 0.91 (95% CI, 0.89 to 0.93) and 0.64 (95% CI, 0.62 to 0.66), respectively. No study used a case-control design. A subgroup analysis involving liquid-based cytology showed a sensitivity of 0.91 (95%CI, 0.89 to 0.93) and specificity of 0.64 (95%CI, 0.61 to 0.66). CONCLUSIONS Our meta-analysis of p16/Ki-67 dual stain studies showed that the test achieved high sensitivity and moderate specificity for p16/Ki-67 immunocytochemistry for high-grade squamous intraepithelial lesion and cervical cancer. We suggest that p16/Ki-67 dual stain might be a reliable ancillary method identifying high-grade squamous intraepithelial lesions in women with abnormal Pap tests. LIMITATIONS No study in the meta-analysis examined the accuracy of the p16/Ki-67 dual stain for interpretation of glandular neoplasms.
Performance Evaluation of the Listed Real Estate Companies in China Based on Fuzzy Neural Networks: The Perspective of Stakeholders

In this paper, we utilize a fuzzy neural network to evaluate the performance of listed real estate companies in China. We analyze the special interests of the stakeholders and construct a performance evaluation indicator system for these companies. We evaluate a sample of listed real estate companies using the fuzzy neural network method to determine their performance. The results show that the scores of the sample companies range within a certain scale (50, 90), and the performance of the different companies varies greatly. The results also show that the trained neural network model can well identify the performance of the listed real estate companies.

The data obtained from the questionnaire are analyzed using frequency, severity and important indices. The reliability test on the data using Crobach’s alpha displays, sixteen success factors were necessary for true satisfaction of successful project implementation in Nigerian Construction Industry. Based on the result, objective management, management of design, technical factors, top management support and risk management were selected as the most critical success factors in project performance. The findings are focused to assist practitioners’ gain better understanding on the key areas based on prioritized success factors in order to improve performance in project delivery.
Improved Rectangular Matrix Multiplication using Powers of the Coppersmith-Winograd Tensor

In the past few years, successive improvements of the asymptotic complexity of square matrix multiplication have been obtained by developing novel methods to analyze the powers of the Coppersmith-Winograd tensor, a basic construction introduced thirty years ago. In this paper we show how to generalize this approach to make progress on the complexity of rectangular matrix multiplication as well, by developing a framework to analyze powers of tensors in an asymmetric way. By applying this methodology to the fourth power of the Coppersmith-Winograd tensor, we succeed in improving the complexity of rectangular matrix multiplication. Let $\alpha$ denote the maximum value such that the product of an $n\times n^\alpha$ matrix by an $n^\alpha\times n$ matrix can be computed with $O(n^{2+\epsilon})$ arithmetic operations for any $\epsilon>0$. By analyzing the fourth power of the Coppersmith-Winograd tensor using our methods, we obtain the new lower bound $\alpha>0.31389$, which improves the previous lower bound $\alpha>0.30298$ obtained five years ago by Le Gall (FOCS'12) from the analysis of the second power of the Coppersmith-Winograd tensor. More generally, we give faster algorithms computing the product of an $n\times n^k$ matrix by an $n^k\times n$ matrix for any value $k\neq 1$. (In the case $k=1$, we recover the bounds recently obtained for square matrix multiplication). These improvements immediately lead to improvements in the complexity of a multitude of fundamental problems for which the bottleneck is rectangular matrix multiplication, such as computing the all-pair shortest paths in directed graphs with bounded weights.
Determinants of Customer Loyalty: An Exploratory Investigation on Relational Benefits in the Context of Customer Club

Although relational benefits identified in previous studies have gained empirical supports in services contexts, their generalisability in a context of customer clubs is yet to be verified. Customer clubs may require different key success factors and its operation needs special environmental considerations. By using focus group interviews among milk product club members, this research found that most of the relational benefits identified in the literatures emerged in the context of customer clubs. Two new relational benefits, information benefits and sharing benefits, have been found which may constitute unique attributes of customer clubs. However, relational benefits may have different interpretations to customer club members. The research provides evidence to explore the generalibility of relational benefits in a context of customer clubs.
Company-Size Effect on the Polish Stock Market

Because of higher financial and operating risks small firms are considered to carry higher investment risks than larger ones. Plenty of empirical research found that relatively small/large companies are characterized by relatively high/low long-term average returns as well as relatively high/low variability of these returns. However, findings of different studies are far from being unequivocal as regards statistical significance, scope, stability and even direction of the relationship between firm-size and long-term risks and returns. In this paper we examine the size-effect on the Polish stock market in 1999-2011 years, using four alternative company-size measures. Our research confirmed the existence of statistically significant and strong negative relationships between long-term stock returns and company-size (with all four company-size variables statistically significant). However, our findings as regards analogous relationships between portfolios’ Betas and company-size turned out to be much more mixed.
Complexities of Household Energy Consumption and Conservation

A national sample of Canadian households was used to relate climatic variables, dwelling/appliance/vehicle descriptors, demographic characteristics, and attitudinal variables to actual in-home energy consumption and self-reported gasoline consumption. Using split-sample replications, dwelling and vehicle descriptors indicated a strong association with energy consumption, and both male and female attitudes indicated weak associations.
Existence of autocrine loop between interleukin‐6 and tranforming growth factor‐β1 in activated rat pancreatic stellate cells

Interleukin (IL)‐6 is a proinflammatory cytokine assumed to participate in pancreatic fibrosis by activating pancreatic stellate cells (PSCs). Autocrine TGF‐β1 is to central in PSC functional regulation. In this study, we examined IL‐6 secretion from culture‐activated rat PSCs and its regulatory mechanism. Activated PSCs express and secrete IL‐6. When anti‐TGF‐β1 neutralizing antibody was added in the culture medium, IL‐6 secretion from activated PSCs was inhibited, whereas exogenous TGF‐β1 added in the culture medium enhanced IL‐6 expression and secretion by PSCs in a dose dependent manner. Infection of PSCs with an adenovirus expressing dominant‐negative Smad2/3 attenuated basal and TGF‐β1‐stimulated IL‐6 expression and secretion of PSCs. We also demonstrated the reciprocal effect of PSCs‐secreted IL‐6 on autocrine TGF‐β1. Anti‐IL‐6 neutralizing antibody inhibited TGF‐β1 secretion from PSCs. Preincubation of cells with 10 nM PD98059, an extracellular signal‐regulated kinase (ERK)‐dependent pathway inhibitor, attenuated IL‐6‐enhanced TGF‐β1 expression and secretion of PSCs. In addition, IL‐6 activated ERK in PSCs. These data indicate the existence of autocrine loop between IL‐6 and TGF‐β1 through ERK‐ and Smad2/3‐dependent pathways in activated PSCs. J. Cell.

PERFORMANCE OF CODED OFDM IN IMPULSIVE NOISE ENVIRONMENT

Noise in the power line channel cannot be described by Additive White Gaussian Noise (AWGN). This channel suffers from impulsive noise and other narrow-band interferences. Impulsive noise, in particular, can degrade the performance of OFDM-based Power Line Communication (PLC) systems significantly. Therefore, channel coding is important to combat the impairments in this hostile medium, where the encoding and decoding of convolution codes over generated symbols for the transmission over impulsive noise channels. The encoder multiplies a vector of information symbols resulting from a modulation scheme choosing the inverse Fourier transforms as; the encoding procedure is similar to orthogonal frequency-division multiplex (OFDM) modulation. Simulation results will show the excellent performance of the Viterbi decoder. The performance of the OFDM is to study and find the probability of error performance verses signal to noise ratio with encoding and without encoding. In this paper, we study and simulate the performance of PLC channels in the presence of impulsive noise.
Comparison of α-Blocker Monotherapy and α-Blocker plus 5α-Reductase Inhibitor Combination Therapy Based on Prostate Volume for Treatment of Benign Prostatic Hyperplasia

OBJECTIVE: This study compared α-blocker monotherapy with combination therapy involving an α-blocker and a 5-α reductase inhibitor for benign prostatic hyperplasia (BPH), according to baseline prostate volume. METHODS: Korean men diagnosed with BPH were randomized to 12 months' treatment with 0.2 mg tamsulosin or 0.2 mg tamsulosin plus 0.5 mg dutasteride. Prostate specific antigen (PSA), prostate volume, transition zone volume (TZV), International Prostate Symptom Score (IPSS), maximal urinary flow rate (Q max), postvoid residual urine volume and sexual function were assessed at baseline and after 12 months' treatment. Variables were analysed based on baseline prostate volumes of ≤ 35 ml or > 35 ml. RESULTS: In total, 216 men with BPH were included. Combination therapy resulted in significant improvements in prostate volume, TZV, PSA, IPSS and Q max, which were most pronounced in men with a prostate volume > 35 ml. CONCLUSIONS: Tamsulosin monotherapy was sufficient treatment for BPH in Korean men with a prostate volume ≤ 35 ml. Combination tamsulosin and dutasteride therapy provided greater benefits than tamsulosin monotherapy in men with BPH whose prostate volume was > 35 ml.
Public Private Partnership to Promote Whole Grain Consumption

A Public Private Partnership promises much and presents an exciting option to increase whole grain consumption. The whole grain content in the Danish diet in 2011–2012 seems to have increased markedly since calculations in 2004. Average whole grain intake is now 60 g/day/10 MJ in 2011–2012. In 2004, it was only 36 g/day/10 MJ (2). The Danish Whole Grain Campaign consists of 34 partners, including government, health organizations, and commercial partners such as producers, millers, gas stations, retailers, and craft bakeries.
