A four-factor framework of consumers' perception of mobile applications in context

Mobile applications are not only integral to the functioning of smart mobile devices (SMD) but also one of the most commonly used technological interfaces within smart networks of connected devices. In order to market these value propositions, companies have to understand how consumers perceive apps in order to present an interface that is well received and allows for the highest benefits for companies and customers alike. From a technical perspective, apps are complex software products, but consumers do not seem to perceive them as such, because they see apps through the "lens" of context. Thus, the context in which apps and associated services are purchased and used considerably influences the way consumers interpret apps and derive val-ue from them. Therefore, this article sheds light on consumers' perception of apps and the role of context in shaping this perception. Based on Yoo's (2010) framework of experiential computing, we develop a framework in which context is structured into four dimensions: personal, technical, functional and social. The framework can be used to get a better understanding of consumers' app perception and related experience and to successfully develop and market apps, provide smart services based on adequate information systems, design app stores, or regulate the legal environment. Moreover, the framework can be applied to other mobile or digital offerings and serve for a better understanding of the perception of value propositions like smart services and devices.
Real-time PCR quantitative assessment of hepatitis A virus, rotaviruses and enteroviruses in the Tyume River located in the Eastern Cape Province, South Africa

We applied real-time RT-PCR (reverse transcription-polymerase chain reaction) to assess the incidence of hepatitis A virus, rotaviruses and enteroviruses in the Tyume River, an important water resource in the impoverished Eastern Cape Province of South Africa. Detection of noroviruses was done using conventional semi-nested RT-PCR. Water samples were collected once monthly from 6 sampling sites over a 12-month period starting in August 2010 and ending in July 2011. Hepatitis A virus was detected in 13% of the samples in concentrations ranging between 1.67×10 3 genome copies/l and 1.64×104 genome copies/l while rotaviruses were detected in 4% of the samples with concentrations ranging from 9×10 1 genome copies/l to 5.64×10 3 genome copies/l. Enteroviruses were not detected in any of the samples, while noroviruses were detected in 4% of the samples. All hepatitis A and rotaviruses positive samples were from the upstream sections of Tyume River while noroviruses were detected in samples from downstream sections only. Statistical analysis showed that occurrence of the viruses in Tyume River was sporadic. Risk analysis showed that hepatitis A virus posed greater risk than rotaviruses for both recreational and domestic water uses. Because of the low infectious dose of enteric viruses, the detection of even low concentrations of hepatitis A virus, rotaviruses and noroviruses in surface water poses a significant risk to public health.

Satisfaction level and masticatory performance of patient rehabilitated with implant-supported overdentures = Nível de satisfação e performance mastigatória de pacientes reabilitados com sobredentaduras suportada por implantes

Purpose : To compare the masticatory performance and satisfaction levels of subjects with normal dentition and subjects with implant-supported overdentures with two types of attachments (ball and bar-clip retention systems). Methods : The sample comprised 24 subjects, 12 edentulous patients and 12 dentate subjects. The denture wearers received two dental implants and new maxillary and mandibular dentures. Three months after the first surgical phase, the mandibular dentures were connected to the implants by a gold ball attachment. Two months later new mandibular overdentures were made with a bar-clip attachment. Satisfaction levels (modified OHIP-EDENT and verbal rating scale) and masticatory performance (chewing for 40 masticatory cycles) were measured with the old dentures, with the unattached new dentures, and with the new dentures with ball and bar-clip attachments. Data were analyzed by Friedman and chi-square tests. Results : Both masticatory performance and satisfaction levels significantly improved after implant treatment. No significant differences were observed between the overdentures with ball and bar attachments. However, the masticatory performance after treatment was still significantly lower than the performance of the healthy subjects. Conclusion : The rehabilitation of edentulous patients with overdenture with ball or bar-clip attachment improves both satisfaction and masticatory performance, but the outcomes levels are not equal as those found for dentate subjects.
Interactive comment on “ Impacts of Antarctic runoff changes on the Southern Ocean sea ice in an eddy-permitting sea ice-ocean model ” by V .

GENERAL COMMENTS Numerical models are the ideal tool for undertaking experiments on complex natural systems when attempting to understand the mechanics of the system and how it might change into the future. This paper presents the results of a set of numerical model experiments on one of Earth’s major state changes, i.e. the freezing in autumn and winter of the Southern Ocean adjacent to the Antarctic Continent. What is more, Southern Ocean sea ice is baffling in that its extent has been increasing even as global air temperatures have increased. This paper investigates how much of the expansion of sea ice extent is caused by increased freshwater runoff from the Continent. The paper is therefore of interest not only for scientific reasons
Effects of a Diet Supplemented with Japanese Grape (Hovenia dulcis) Seed Oil on the Omega-3 and Nutritional Lipid Quality in Nile Tilapia (Oreochromis niloticus)

In this study, the fatty acid (FA) composition of the Japanese grape (Hovenia dulcis) seed oil (JGSO) was firstly evaluated. It was found that the seed oil is rich in alpha-linolenic acid (LNA), containing approximately 425 mg LNA g of total lipids. A fish diet supplemented with JGSO was prepared and supplied to Nile tilapia to investigate the FA composition of the fillets. For this, Nile tilapia were submitted to two feeding treatments: a control diet with 4.2% of soybean oil, and a diet supplemented with 4.2% of JGSO. The LNA, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) values increased significantly (406, 153 and 126%, respectively) with JGSO in the diet and with an increase in feeding time, while the nutritional quality indexes, n-6/n-3 ratio and index of thrombogenicity, decreased 2.8 and 1.4 times, respectively. Thus, the replacement JGSO in the diet raised the nutritional lipid quality in Nile tilapia.
Numerical analysis of a finite volume scheme for the simulation of a nonlinear degenerate breast cancer model

In this paper, a finite volume method for the simulation of a degenerate breast cancer model is carried on. This model consists in modeling the stepwise mutations from a normal breast stem cell to a tumor cell. Furthermore, the model presents a degenerate parabolic equation modeling the invasion and interaction of the solid tumor growth with its surrounding by means of releasing degradative enzymes which their dynamics are modeled with a partial differential equation. We show that the proposed finite volume scheme ensures the discrete maximum principle and we prove the convergence of existed discrete solutions toward a weak solution. Finally, a numerical experiment is carried out to show the breast cancer development.
Regional Trade and Logistics Infrastructure: A Spatial Approach

This paper aims to analyze whether the existing logistics platforms network in Spain affects Spanish transport demand by using a spatial framework. In particular, we use demand for transport to export goods to other Spanish provinces as a proxy for logistics infrastructure demand in Spain. Then, we obtain data for trade flows between provinces (NUTS3) in the year 2007. We also obtain data about the number and area of logistics platforms existing in each Spanish province to proxy for the transportation network structure in Spain. In a first step, we construct weight matrixes considering first-order contiguity and we obtain that spatial dependence is significant in a spatial econometric model of commodity flows (LeSage and Polasek, 2008). Secondly, we incorporate logistics network structure dependence into the model so that the spatial lags measure the impact and significance on trade flows from all origins to all destinations by considering the importance of logistics performance in the neighboring provinces. Finally, we perform the analysis for different economic activities. The results obtained provide evidence about the role of the location of logistics platforms for satisfying existing demand for transport structure in the Spanish provinces.
Blood tissue cytological status of prognosis and predictive markers in the natural history of solid cancer development

Cancer is the major burden of disease worldwide. Each year, tens of millions of people are diagnosed with cancer around the world, and more than half of the patients eventually die from it. In many countries, cancer ranks the second most common cause of death following cardiovascular diseases. With significant improvement in treatment and prevention of cardiovascular diseases, cancer has or will soon become the number one killer in many parts of the world. The aim of this study was to optimize the means to support and diagnose early people living with solid cancers through blood exploration using flow cytometry. The techniques used included; complete blood count (CBC), flow cytometry and microscopy slides (smear). The data obtained from the microscopic analysis of blood cells searching for alterations after smear colored blade by May Grunwald Giemsa (MGG), revealed changes in size (anisocytosis) and shape (poikilocytosis) of erythrocytes with total absence of neutrophils. The main blood pathologies associated with these types of cancer obtained after CBC were: hypoglobinemia (30.76%), blood-concentration (18.75%) which marked the character of hypochromic blood tissue (true anemia), monocytosis (12.82%) and erythrocytopenia (12.82%). The decrease in the number of granules of polymorphonuclear cells and changes in the shapes of nuclei (lobularity) were observed in most patients, using the flow cytometry technique. Thus, alterations of blood tissue in solid cancers were identified and an algorithm for their exploitation has been developed to contribute to the understanding of natural history of solid cancer. Key words: Solid cancer, epidemiology, cytological markers, flow cytometry.

We tried to draw a practical system with supplier-based perspective using interaction approach. Second, we introduced new electronic tools and facilities in order to perform process of trading activities and new approach of development of business relationships, and re- design process. For evaluation of designed system, we had a trial in SIFCO as a trading company for steel materials and assessed the data in result of implementation system and finally we measured performance of system with considering two criteria: Time and Accuracy. 
Municipal wastewater treatment in a membrane bioreactor.

A membrane bioreactor (MBR) with a submerged membrane was used for the treatment of municipal wastewater from the city of Zagreb, Croatia, in a continuous mode for 123 days. The MBR was very efficient in organic matter removal (92.3 and 98.5 % for COD and BOD, respectively) for the entire duration of the experiment. Nitrification was established after 20 days remaining stable and efficient with a low concentration of ammonia and nitrite in the effluent. On average, 87% of ammonia was converted to nitrate. Biomass concentration, measured as MLSS, was dependant on the organic loading rate (OLR) and food to microorganism ratio (F/M), and its growth could be stopped or its concentration reduced by setting OLR and F/M to appropriate values, thus reducing the excess sludge production. Throughout the range of hydraulic retention times from 2.6 to 5.9 h, the efficiencies of organic matter removal and nitrification were not affected.
Model for the Mass Transport during Metal-Assisted Chemical Etching with Contiguous Metal Films As Catalysts

Metal-assisted chemical etching is a relatively new top-down approach allowing a highly controlled and precise fabrication of Si and Si/Ge superlattice nanowires. It is a simple method with the ability to tailor diverse nanowire parameters like diameter, length, density, orientation, doping level, doping type, and morphology. In a typical metal-assisted chemical etching procedure, a Si substrate is covered by a lithographic noble metal film and etched in a solution containing HF and an oxidant (typically H2O2). In general, the function of the metal is to catalyze the reduction of H2O2, which delivers electronic holes necessary for the oxidation and subsequent dissolution of the Si oxide by HF. However, the details of the etching process using contiguous metal thin films, especially the mass transport of reactants and byproducts are still not well understood. In this study, the etching mechanism was systematically investigated. Several models of metal-assisted chemical etching using a contiguous metal film.

Programmable Input Mode Instrumentation Amplifier Using Multiple Output Current Conveyors

In this paper a programmable input mode instrumentation amplifier (IA) utilising second generation, multiple output current conveyors and transmission gates is presented. Its main advantage is the ability to choose a voltage or current mode of inputs by setting the voltage of two configuration nodes. The presented IA is prepared as an integrated circuit block to be used alone or as a sub-block in a microcontroller or in a field programmable gate array (FPGA), which shall condition analogue signals to be next converted by an analogue-to-digital converter (ADC). IA is designed in AMS 0. 35μm CMOS technology and the power supply is 3.3 V; the power consumption is approximately 9.1 mW. A linear input range in the voltage mode reaches ± 1.68 V or ± 250 μA in current mode. A passband of the IA is above 11 MHz. The amplifier works in class A, so its current supply is almost constant and does not cause noise disturbing nearby working recision analogue circuits.
On the c-Si surface passivation mechanism by the negative-charge-dielectric Al2O3

Al2O3 is a versatile high-κ dielectric that has excellent surface passivation properties on crystalline Si (c-Si), which are of vital importance for devices such as light emitting diodes and high-efficiency solar cells. We demonstrate both experimentally and by simulations that the surface passivation can be related to a satisfactory low interface defect density in combination with a strong field-effect passivation induced by a negative fixed charge density Qf of up to 1013 cm−2 present in the Al2O3 film at the interface with the underlying Si substrate. The negative polarity of Qf in Al2O3 is especially beneficial for the passivation of p-type c-Si as the bulk minority carriers are shielded from the c-Si surface. As the level of field-effect passivation is shown to scale with Qf2, the high Qf in Al2O3 tolerates a higher interface defect density on c-Si compared to alternative surface passivation schemes.
Three-dimensional S-wave structure of the upper mantle beneath Turkey from surface wave tomography

SUMMARY A 3-D upper-mantle structure beneath Turkey is investigated using phase speeds of fundamental-mode Rayleigh waves employing a conventional two-station method with high-density seismic networks in Turkey. We analyse 289 seismic events with moment magnitude 5.5 and greater, and with focal depth shallower than 100 km between 2006 and 2008. Waveform data are derived from 164 three-component broad-band seismic stations operated by two national seismic networks. At first, Rayleigh-wave phase speed maps are obtained from the inversion of two-station phase speeds using about 1000–3000 paths, depending on the period of Rayleigh waves. The three-dimensional S-wave model is then obtained in the depth range from 40 to 180 km using the phase speed maps in the period range from 25 to 120 s. Our model reveals the fast anomalies in the north of Cyprus associated with the subducted portion of the African oceanic lithosphere from the Cyprus trench. We identify a vertical discontinuity of the fast anomaly associated with the Cyprus slab starting at 60–80 km depth which may represent a minor tear of the Cyprus slab. We observed that the western part of the Cyprus slab is getting closer to the edge of the Hellenic slab beneath the Isparta Angle (IA) and Antalya Basin. Our model also indicates a slow wave speed anomaly beneath the IA and Antalya Basin probably due to hot materials of asthenosphere rising from a tear of the subducted African oceanic lithosphere; that is, a slab tear between the Cyprus and the Hellenic subductions. In the eastern part of Turkey, a widespread slow anomaly appears in the model that corresponds to the Eastern Anatolian Accretionary Complex (EAAC). Our model shows a fast anomaly beneath the EAAC that can be interpreted as the detached portion of the subducted Arabian lithosphere.
An Empirical Analysis of Customer Choice of Banks in Ghana

The deregulation and liberalization of the financial sector as well as the enactment of the new banking law in 1988 has led to increased competition in the Ghanaian banking sector. Given the dynamic nature of the business environment in Ghana coupled with the fact that customers have become more demanding and highly sophisticated, it has become imperative for financial institutions especially banks to develop strategies and products to attract and retain customers. The current study analyses the factors that bank customers consider important in their choice of banks. The study used primary data from field survey using questionnaire as the instrument. Both descriptive and multivariate statistical methods were used to analyse the data. It was found that the most important factors influencing customer choice of a bank are location of the bank, extension of working hours by the bank, availability of ATM facility, provision of efficient services, the bank being a private one and introduction of customers to the bank by friends and relatives. It is recommended that there should be frequent marketing research by the banks to monitor and evaluate the ever changing customer peculiarities and perspectives in order to develop products or services to meet the current tastes of their customers. Key w ords: Ghana, Choice of Banks, Eigen values, Reliability test.
A Rotation Invariant Pattern Operator for Texture Characterization

Summary This paper proposes a novel Ternary Pattern Operator for texture characterization. The devised operator has rotation-invariant capability. The operator is used for extracting texture features from the images. From these features the texture present in the image are identified. The operator can be realized with few operations in local neighborhood and hence it is computationally simple. In the training phase the classifier is trained with samples with one particular angle and tested with samples of different angles. A detailed analysis is presented for rotation angles of misclassified samples. A distribution based classification approach is used for discriminating the textures. A probabilistic model is built for each texture class. A classification problem of different Brodatz texture and seven rotation angles is used in experiments. Experimental results prove that the performance of the proposed operator for feature extraction is appreciable.
Effect of the field of view and semantic content of the stimulus on accommodation stimulated with a volumetric Badal optometer

The capability of the human eye to focus near targets is the so-called concept of Accommodation. This concept has been comprehensively studied since the last century, however, there are still many issues related to it that are not fully clear. Additionally, since the apparition of virtual reality (VR) technologies accommodation has been given an increasing relevance since it is thought to be one of the key points for the success in VR development and implementation. In other words, an appropriate representation of focus cues (i.e., accommodation and peripheral depth cues) i
Financial Markets First Draft : September 1 , 2010 — This draft : May 23 , 2018

This paper studies invariance relationships in tick-by-tick transaction data in the U.S. stock market. Over 1993–2001, monthly regression coefficients of the log of the trade arrival rate on the log of trading activity have an almost constant value of 0.666, close to the value of 2/3 predicted by market microstructure invariance. Over 2001–2014, after decimalization and the increasing use of electronic order matching systems and algorithmic trading, the coefficients increase to about 0.79. The evidence suggests that changes in fit are due to increasing importance of minimum lots sizes in a world where algorithmic traders shred their orders.
Decomposition of productivity growth of the malaysian manufacturing sector, 1983-2005

The present paper examines the productivity growth of Malaysian manufacturing industries between 1983 and 2005. Unlike previous studies that use one source of data, the present study uses two sources of data:the Malaysian Input- Output Tables and the Malaysian Industrial Manufacturing Survey. The analysis focuses upon on the decomposition of aggregate total factor productivity (TFP) growth into three effects: technical change, linkage and final demand. The findings indicate that final demand is the largest contributor to growth in overall TFP. In addition, a small contribution stems from technical change and particularly linkage effects. When the decomposition of final demand effect is extended into price and real share effects, the findings obtained demonstrate that a change in relative prices significantly influences the change in output share produced.
