Applying Theory of Perceived Risk and Technology Acceptance Model in the Online Shopping Channel A

As the advancement of technology, online shopping channel develops rapidly in recent years. According to the report of Taiwan Network Information Center, there are almost eighty percents of internet population shopping in online channel. Synthesizing insights from the previous research, this study develops the conceptual model to integrate Theory of Perceived Risk (TPR) and Technology Acceptance Model (TAM) to apply in online shopping. Using data collected from 637 respondents from online survey website, we use structural equation modeling to test measurement and structural models. The results suggest the need for consideration of perceived risk as an antecedent in the Technology Acceptance Model. The limitations and implications are discussed. Keywords—perceived risk, perceived usefulness, perceived ease of use, behavioral intention, actual purchase behavior
Age moderates response to acceptance and commitment therapy vs. cognitive behavioral therapy for chronic pain.

OBJECTIVE
The purpose of this study was to examine age differences in response to different forms of psychotherapy for chronic pain.


METHODS
We performed a secondary analysis of 114 adults (ages 18-89 years) with a variety of chronic, nonmalignant pain conditions randomly assigned to 8 weeks of group-administered acceptance and commitment therapy (ACT) or cognitive behavioral therapy (CBT). Treatment response was defined as a drop of at least three points on the Brief Pain Inventory-interference subscale.


RESULTS
Older adults were more likely to respond to ACT, and younger adults to CBT, both immediately following treatment and at 6-month follow-up. There were no significant differences in credibility, expectations of positive outcome, attrition, or satisfaction, although there was a trend for the youngest adults (ages 18-45 years) to complete fewer sessions.


CONCLUSIONS
These data suggest that ACT may be an effective and acceptable treatment for chronic pain in older adults.
Intentional avoidance of the esophagus using intensity modulated radiation therapy to reduce dysphagia after palliative thoracic radiation

BACKGROUND
Palliative thoracic radiotherapy is an effective technique to alleviate symptoms of disease burden in advanced-stage lung cancer patients. Previous randomized controlled studies demonstrated a survival benefit in patients with good performance status at radiation doses of 35Gy10 or greater but with an increased incidence of esophagitis. The objective of this planning study was to assess the potential impact of esophageal-sparing IMRT (ES-IMRT) compared to the current standard of care using parallel-opposed pair beams (POP).


METHODS
In this study, 15 patients with lung cancer treated to a dose of 30Gy in 10 fractions between August 2015 and January 2016 were identified. Radiation treatment plans were optimized using ES-IMRT by limiting the max esophagus point dose to 24Gy. Using published Lyman-Kutcher-Burman normal tissue complication probabilities (LKB-NTCP) models, both plans were evaluated for the likelihood of esophagitis (≥ grade 2) and pneumonitis (≥ grade 2).


RESULTS
Using ES-IMRT, the median esophageal and lung mean doses reduced from 16 and 8Gy to 7 and 7Gy, respectively. Using the LKB models, the theoretical probability of symptomatic esophagitis and pneumonitis reduced from 13 to 2%, and from 5 to 3%, respectively. The median normalize total dose (NTD mean) accounting for fraction size for the GTV and PTV of the clinically approved POP plans compared to the ES-IMRT plans were similar.


CONCLUSION
Advanced radiotherapy techniques such as ES-IMRT may have clinical utility in reducing treatment-related toxicity in advanced lung cancer patients. Our data suggests that the rate of esophagitis can be reduced without compromising local control.
Plagioclase Peridotites in Ocean^Continent Transitions: Refertilized Mantle Domains Generated by Melt Stagnation in the Shallow Mantle Lithosphere

The existence of different mantle domains exposed in ocean^ continent transition zones provides a framework for understanding the generation of ultramafic seafloor along magma-poor rifted margins. In this study we present detailed petrological and geochemical data on peridotites from the Eastern Central Alps ophiolites in Switzerland and Italy to identify different mantle domains, to estimate the extent of refertilization, and to test whether refertilization is associated with a thermal signature that has important implications for geophysical interpretations of ocean^continent transitions. The compositions of clinopyroxene, orthopyroxene and spinel clearly reflect the different mantle domains. Relative to clinopyroxenes from spinel peridotites, clinopyroxenes from plagioclase peridotites have lower Na2O and Sr contents, but higher middle to heavy rare earth element ratios and Zr concentrations, and different Sc^V relationships. Spinels in plagioclase peridotites have higherTiO2 and lower Mg-numbers compared with those in spinel peridotites. Mineral^ mineral trace element partitioning suggests that spinel peridotites equilibrated at substantially lower temperatures than plagioclase peridotites.The temperature difference between the spinel and plagioclase peridotites indicates an important thermal boundary between the two. The geochemical data show systematic spatial variations. A heterogeneous, ‘subcontinental domain’ with no syn-rift melt imprint is separated from a ‘refertilized domain’ that exhibits a complex history of regional-scale melt infiltration and melt^rock reaction, which has erased most of the ancient history. Simple calculations suggest that up to 12% of mid-ocean ridge basalt-type melt can be stored in plagioclase peridotite, relative to a depleted residue. Such a ‘lithospheric sponge’ provides an explanation for the fertile compositions of the peridotites and the rare occurrence of volcanic rocks in magma-poor rifted margins. We suggest that magma-poor vs magma-rich margins are largely determined by the efficiency of melt extraction and not so much by melt generation processes, given a similar initial composition of the upwelling mantle. It is proposed that refertilization increases textural diversity and chemical heterogeneity related to shallow crystallization in the mantle lithosphere.
Designing Language Courses: A Guide for Teachers

Designing Language Courses comprises 10 chapters on various aspects of course design, including areas such as “Assessing Needs,” “Formulating Goals and Objectives,” “Developing Materials,” and “Adapting a Textbook,” as well as the perhaps less predictable topic of “Articulating Beliefs” (i.e., the teacher’s own beliefs about language teaching and learning). While the chapters appear in an order which, with a couple of exceptions, reflects a fairly conventional sequence of processes of course design, the writer points out in her first chapter that she thinks in terms of a “systems approach” to the activity; she regards the various elements of course design as an interrelated and systematic whole, what she calls a “framework” for course design, where “as a course designer, you can begin anywhere in the framework, as long as it makes sense to you to begin where you do” (p. 3). Graves feels that conventional writing on course design views the process as a highly organized, linear one, in contrast to the “messy, multi-faceted, two-steps-forward one-step-back process” (p. 2) which she herself experienced in designing courses and which she feels is the reality for the majority of teachers.

An ultra-low-voltage ultra-low-power OTA with improved gain-bandwidth product

A 0.5-V ultra-low-power improved operational transconductance amplifier (OTA) using the transistors operate in weak inversion is presented in this paper. The proposed topology based on a bulk-driven input differential pair employed a gain-stage in the Miller capacitor feedback path to improve the ¿pole-splitting¿ effect. Simulations in a standard 0.18 ¿m CMOS process resulted on rail-to-rail input and output swings, considerable enhancement in unity-gain bandwidth and also the DC gain with the power consumption of only 1.02 ¿W.
Electronic structure of amorphous InGaO3(ZnO)0.5 thin films

Abstract The electronic structure of amorphous semiconductor InGaO 3 (ZnO) 0.5 thin films, which were deposited by radio-frequency magnetron sputtering process, was investigated using X-ray photoelectron spectroscopy and O K -edge X-ray absorption spectroscopy. The overall features of the valence and conduction bands were analyzed by comparing with the spectra of Ga 2 O 3 , In 2 O 3 , and ZnO films. The valence and conduction band edges are mainly composed of O 2 p and In 5 sp states, respectively. The bandgap of the films determined by spectroscopic ellipsometry was approximately 3.2 eV. Further, it is found that the introduction of oxygen gas during the sputter-deposition does not induce significant variations in the chemical states and band structure.
Early and long-term outlook of percutaneous coronary intervention for bifurcation lesions in young patients.

BACKGROUND
Coronary artery disease is most common in older patients, but may occur in younger subjects. The outlook of young patients after percutaneous coronary intervention (PCI) of challenging lesion subsets such as coronary bifurcations, is not established. We thus aimed to appraise the early and long-term results of PCI for bifurcations in young patients.


METHODS
A multicenter, retrospective study was conducted enrolling consecutive patients undergoing bifurcation PCI between 2002 and 2006 in 22 Italian centers. Patients were divided in 2 groups: age ≤ 45 years, and age > 45 years. The primary end-point was long-term rate of major adverse cardiac events (MACE).


RESULTS
4,314 patients were included: 195 (4.5%) in the younger group, and 4119 (95.5%) in the older group. 30-day outcomes did not show significant differences in MACE rates, with 1.0% in the ≤ 45 years group and 2.1% in the >45 years group (p=0.439), with death in 0.5% and 1.2% (p=0.388). At long-term follow-up (24.4 ± 15.1 months), younger patients showed similar rates of MACE, (12.8% vs. 16.6%, p=0.161), myocardial infarction (3.1% vs. 3.7%, p=0.633), target lesion revascularization (11.3% vs. 12.5%, p=0.627), or stent thrombosis (1.5% vs. 2.8%, p=0.294), despite an increased risk of death in older patients (1.0% vs. 5.0%, p=0.012). Even at extensive multivariable analysis, younger patients still faced a similar risk of MACE (HR=0.78 [0.48-1.27], p=0.318).


CONCLUSIONS
Despite their low age, young patients undergoing PCI for bifurcation face a significant risk of early and late non-fatal adverse events. Thus, they should not be denied careful medical management and follow-up.

Psoriasis patients with psoriasis Area and Severity Index (PASI) 90 response achieve greater health-related quality-of-life improvements than those with PASI 75-89 response: results from two phase 3 studies of secukinumab.

BACKGROUND
The emergence of new biological therapies showing high and sustained level of Psoriasis Area and Severity Index (PASI) 90 response has provided the possibility of both greater skin clearance and increased quality of life (QOL).


OBJECTIVE
To evaluate the association of greater response in skin clearance with improvements in skin-related QOL up to 52 weeks.


METHODS
Subjects achieving various levels of skin clearance (PASI 90-100 or PASI 75-89) and Dermatology Life Quality Index (DLQI) (0/1) response were compared using ERASURE and FIXTURE trial data. Similar analyses with IGA ratings of Clear or Almost Clear were performed.


RESULTS
Significantly more PASI 90-100 responders at week 12 had DLQI 0/1 response than PASI 75-89 (69.4% vs. 47.1%; p < .001) and sustained DLQI 0/1 response at week 52 (74.0% vs. 56.7%; p < .001). IGA results were similar.


CONCLUSIONS
These results show that PASI 90-100 is a relevant therapeutic goal in moderate to severe psoriasis compared to PASI 75-89 when considering patients' QOL.

Subgrid analysis of liquid jet atomization

The objective of this paper is to study the feasibility of large eddy simulations of a liquid fuel injection in combustion chambers. To do so, a priori analyses of direct numerical simulations are carried out. A complete liquid jet atomization, from the injector down to the end of the liquid core, is simulated thanks to the coupling of both level-set and VOF formulations. To avoid the apparition of a subgrid term in the right hand side of the continuity equation, the choice was made to consider an incompressible formulation as far as the filtering operator is concerned. The corresponding LES transport equations and various subgrid contributions are thus presented. Results are first dedicated to the estimation of the various orders of magnitude of these subgrid terms. In a second part, classical eddy viscosity scale similarity models are tested against the prevalent ones. It appears that, contrary to a Smagorinsky formulation, the scale similarity assumption provides a better estimation of the subgrid terms. This result is found for all locations that have been considered in the jet: at the injection level or in the atomized area. The major drawback is the presence of a constant that needs to be estimated. Various values are found depending on the filter size.
Argos: A Novel 3-DoF Parallel Wrist Mechanism

This article presents a novel parallel spherical mechanism called Argos with three rotational degrees of freedom. Design aspects of the first prototype built of the Argos mechanism are discussed. The direct kinematic problem is solved, leading always to four nonsingular configurations of the end effector for a given set of joint angles. The inverse-kinematic problem yields two possible configurations for each of the three pantographs for a given orientation of the end effector. Potential applications of the Argos mechanism are robot wrists, orientable machine tool beds, joy sticks, surgical manipulators, and orientable units for optical components. Another pantograph based new structure named PantoScope having two rotational DoF is also briefly introduced. KEY WORDS—parallel robot, machine tool, 3 degree of freedom (DoF) wrist, pure orientation, direct kinematics, inverse kinematics, Pantograph based, Argos, PantoScope
Maximizing Output Power of a Solar Panel via Combination of Sun Tracking and Maximum Power Point Tracking by Fuzzy Controllers

In applications with low-energy conversion efficiency, maximizing the output power improves the efficiency. The maximum output power of a solar panel depends on the environmental conditions and load profile. In this paper, a method based on simultaneous use of two fuzzy controllers is developed in order to maximize the generated output power of a solar panel in a photovoltaic system: fuzzy-based sun tracking and maximum power point tracking. The sun tracking is performed by changing the solar panel orientation in horizontal and vertical directions by two DC motors properly designed. A DC-DC converter is employed to track the solar panel maximum power point. In addition, the proposed system has the capability of the extraction of solar panel I-V curves. Experimental results present that the proposed fuzzy techniques result in increasing of power delivery from the solar panel, causing a reduction in size, weight, and cost of solar panels in photovoltaic systems.
Handling categorical variables in effort estimation

Background: Accurate effort estimation is the basis of the software development project management. The linear regression model is one of the widely-used methods for the purpose. A dataset used to build a model often includes categorical variables denoting such as programming languages. Categorical variables are usually handled with two methods: the stratification and dummy variables. Those methods have a positive effect on accuracy but have shortcomings. The other handing method, the interaction and the hierarchical linear model (HLM), might be able to compensate for them. However, the two methods have not been examined in the research area. Aim: giving useful suggestions for handling categorical variables with the stratification, transforming dummy variables, the interaction, or HLM, when building an estimation model. Method: We built estimation models with the four handling methods on ISBSG, NASA, and Desharnais datasets, and compared accuracy of the methods with each other. Results: The most effective method was different for datasets, and the difference was statistically significant on both mean balanced relative error (MBRE) and mean magnitude of relative error (MMRE). The interaction and HLM were effective in a certain case. Conclusions: The stratification and transforming dummy variables should be tried at least, for obtaining an accurate model. In addition, we suggest that the application of the interaction and HLM should be considered when building the estimation model.
A DIVINE CONSISTENCY PROOF FOR MATHEMATICS by

We present familiar principles involving objects and classes (of objects), pairing (on objects), choice (selecting elements from classes), positive classes (elements of an ultrafilter), and definable classes (definable using the preceding notions). We also postulate the existence of a divine object in the formalized sense that it lies in every definable positive class. ZFC (even extended with certain hypotheses just shy of the existence of a measurable cardinal) is interpretable in the resulting system. This establishes the consistency of mathematics relative to the consistency of these systems. Measurable cardinals are used to interpret and prove the consistency of the system. Positive classes and various kinds of divine objects have played significant roles in theology. 1. T1: Objects, classes, pairing. 2. T2: Extensionality, choice operator. 3. T3: Positive classes. 4.

Measurement of finite-frequency current statistics in a single-electron transistor

Electron transport in nanoscale structures is strongly influenced by the Coulomb interaction that gives rise to correlations in the stream of charges and leaves clear fingerprints in the fluctuations of the electrical current. A complete understanding of the underlying physical processes requires measurements of the electrical fluctuations on all time and frequency scales, but experiments have so far been restricted to fixed frequency ranges, as broadband detection of current fluctuations is an inherently difficult experimental procedure. Here we demonstrate that the electrical fluctuations in a single-electron transistor can be accurately measured on all relevant frequencies using a nearby quantum point contact for on-chip real-time detection of the current pulses in the single-electron device. We have directly measured the frequency-dependent current statistics and, hereby, fully characterized the fundamental tunnelling processes in the single-electron transistor. Our experiment paves the way for future investigations of interaction and coherence-induced correlation effects in quantum transport.
The effects of mastery on pain and fatigue resolution.

PURPOSE/OBJECTIVES
To determine whether mastery, the personal control felt over occurrences perceived to have an important effect on one's life, influences the resolution of pain and fatigue severity.


DESIGN
Secondary data analysis of two randomized clinical trials.


SETTING
Accrual from two comprehensive cancer centers, one community oncology program, and six hospital-affiliated ambulatory oncology centers.


SAMPLE
330 patients with solid tumors who were undergoing chemotherapy and receiving a nurse-presented, six-contact, eight-week intervention for symptom management.


METHODS
Analysis included baseline and interventional data. Logistic regression and survival analysis methods were used to explain relationships between mastery and time to resolution and resolution of pain and fatigue severity.


MAIN RESEARCH VARIABLES
Mastery, pain and fatigue severity resolution, and time to resolution.


FINDINGS
No significant differences in mastery were found among key socioeconomic and cancer-related variables. Mastery was a significant predictor of pain resolution status but did not significantly decrease time to resolution. Mastery did not have a significant effect on fatigue resolution status or time to fatigue resolution after adjusting for other covariates.


CONCLUSIONS
Mastery was symptom specific, predicting pain resolution but not fatigue. Cancer may have an equalizing effect on mastery early in diagnosis and treatment.


IMPLICATIONS FOR NURSING
Nurses should develop interventions that increase mastery in patients with cancer, which may lead to improved resolution of pain. Additional research is needed to explore how mastery may affect resolution of pain severity and other symptoms experienced by people with cancer.

Transitional dynamics and the distribution of wealth in a neoclassical growth model

The evolution of the personal distribution of wealth in a standard neoclassical growth model is studied. If the economy is growing toward the steady state and preferences are such that marginal utility from consumption is infinite (finite) at some (all) positive (non-negative) consumption level(s), then the average saving propensity of agents is positively (negatively) related to their wealth. If the economy is decaying toward the steady state, these relationships are reversed. If wealth and average saving propensity are positively (negatively) related, the distribution of current period wealth Lorenz-dominates (is Lorenz-dominated by) next period’s distribution of wealth.
