The March of Mobile Marketing: New Chances for Consumer Companies, New Opportunities for Mobile Operators

ABSTRACT The mobile channel offers an exciting opportunity for marketers—one that most have yet to fully embrace. One avenue to pursue is the creation of a branded mobile offering, in which the marketer creates a portal dedicated to its product, service, or brand. With constant access to each customer, branded mobile portals can build interactive relationships by identifying consumers not only in terms of personal identity, but also in terms of commercial behavior, geographic location, and social and communication patterns. When consumers sign up for a branded mobile channel, they get access to a variety of distinct offerings that can include exclusive content as well as applications, games, special opportunities, incentives, and emotional experiences—all of which reinforce the value of the sponsoring brand far beyond its standard uses. The rewards for companies that capitalize on these possibilities—deeper engagement with consumers, increased brand loyalty, and enhanced customer lifetime value—are not to be missed.
Detection of C60 and C70 in a Young Planetary Nebula

Cosmic Fullerenes Since the discovery of the buckminsterfullerene C60 in laboratory experiments, it has been speculated that fullerenes could form abundantly in carbon-rich evolved stars and, because of their stability, survive the harsh radiation field in the interstellar medium as a gas-phase species. Cami et al. (p. 1180; published online 22 July; see the Perspective by Ehrenfreund and Foing) have detected large amounts of fullerenes in a peculiar planetary nebula with an extremely hydrogen-poor dust formation zone. Contrary to expectations, the fullerenes are not gaseous; they are cool, are in a neutral charge state, and represent about 1.5% of the available carbon. Hydrogen-poor conditions allow fullerenes to form in space. In recent decades, a number of molecules and diverse dust features have been identified by astronomical observations in various environments. Most of the dust that determines the physical and chemical characteristics of the interstellar medium is formed in the outflows of asymptotic giant branch stars and is further processed when these objects become planetary nebulae. We studied the environment of Tc 1, a peculiar planetary nebula whose infrared spectrum shows emission from cold and neutral C60 and C70. The two molecules amount to a few percent of the available cosmic carbon in this region. This finding indicates that if the conditions are right, fullerenes can and do form efficiently in space.
An Immersive Telepresence System Using a Real-Time Omnidirectional Camera and a Virtual Reality Head-Mounted Display

Current telepresence systems are limited by the use of standard, narrow angle of view cameras. By using an Omni directional camera, an improved visual telepresence system is achieved. This work presents a more immersive visual experience using the Omni directional Panoptic camera in combination with a modern, low cost virtual reality head-mounted display. The camera system and its video data format are briefly described. The presented system is capable of broadcasting the Omni directional live stream via network connection. The system consists of the Panoptic camera as the acquisition device, a personal computer providing server support, and a head-mounted display connected to a client computer. The server and the client application that create a virtual environment from the video data are presented and the test setup is shown. Finally, a video example of the system's real-time operation is provided.
Simulations on 130 nm technology 6T SRAM cell for Near-Threshold operation

In the field of IC technologies, there is a constant demand for energy efficiency solutions. Near-Threshold Computing (NTC) is a technique that reduces energy consumption of IC devices, but it also makes them slower. We are applying NTC to a device constructed in 130 nm CMOS technology in the purpose of designing reasonably priced low-power IC devices suitable for low performance applications. In this paper, we concentrate on how a conventional 6T SRAM cell behaves in NTC use. Memory consumes a considerable portion of area and energy of a common IC system, and therefore it is a good target for optimizing with low-energy solutions. Applying NTC to 6T SRAM is not as straightforward as merely using lower supply voltage and slower clock speed; transistor sizes inside the memory cell have to be carefully considered to make the memory reliable. Two inner NMOS transistors in 6T SRAM cell play an important role; by doubling their widths from the minimum, the reliability and the static energy consumption are improved considerably. Overall, NTC makes it possible to achieve notable savings in the energy consumption of 6T SRAM cell.
Large shareholders, capital structure and diversification of Malaysian public listed manufacturing firms

The study examines the interaction effects of large shareholders, capital structure and diversification on a firm’s value. The findings show that diversification is non-linearly related to a firm’s value. At the lower levels of diversifications, increased diversification is found to improve firm value. However, as the number of diversifications increased, it induces a negative impact on the differences in Tobin’s Q value. The evidence shows that the interaction terms for diversification and excessive leverage enhance firms’ performance suggesting the benefits of diversification in this economy. Further analysis reveals that regardless of the large shareholder-controlling stake, the presence of large shareholders appears to reduce the positive effects of diversification and leverage. Key words: Large shareholders, capital structure, ownership structure, diversification, Malaysia.
Expression of the complement C3a and C5a receptors after permanent focal ischemia: An alternative interpretation

The receptors for the complement anaphylatoxins C3a and C5a are expressed by glial cells and neurons in normal and inflamed brain. Previous studies demonstrated modest elevations in mRNA expression of these receptors in a model of focal cerebral ischemia. Using a similar model system for both mice and rats, we report markedly different patterns of anaphylatoxin receptor mRNA expression in cerebral ischemia. C5a receptor expression was dramatically elevated within 3 h after middle cerebral artery occlusion, while C3aR expression was reduced to 25% of control animals. By 24 h post‐occlusion, expression of both receptors was higher than at any other time point examined. This increased expression at late time points after occlusion is most likely the result of massive infiltration of leukocytes expressing the receptors. We also observed increased receptor mRNA expression in sham‐operated animals, indicating that the procedures used for arterial occlusion affects mechanisms regulating receptor expression. This latter result highlights the importance of including this important control group in ischemic model systems for proper interpretation of changes in gene expression.

Metastatic capacity and intercellular communication between normal cells and metastatic cell clones derived from a rat mammary carcinoma.

Three highly metastatic clones and two weakly metastatic clones were obtained from a spontaneously arising mammary carcinoma in an SHR rat. The difference in their capacity to generate metastatic ability was recognized when the tumor cells were implanted s.c. but not when they were implanted i.v. This evidence possibly indicates that the difference in the metastatic capacity of these clones is caused by different potential for detachment from the primary site and for intravasation during the various steps of metastasis. There are no differences between highly and weakly metastatic clones with regard to their in vitro growth characteristics (doubling time, saturation density, plating efficiency, etc.), homotypic aggregation, and adhesiveness to plastic matrices and fibroblast monolayers. Therefore, we used a dye transfer method to examine the relationship between the metastatic capacity of tumor cells and the capacity of tumor cells to make junctional communication with normal fibroblasts. We found that the incidence of intercellular communication between weakly metastatic clone cells and fibroblasts (derived from normal s.c. tissues and tumor tissues) was significantly higher than that between highly metastatic clone cells and fibroblasts. These results suggest that junctional communication between tumor cells and normal fibroblasts may play a part in the early stage of cancer metastasis.
THROMBOPHILIC RISK FACTORS ARE UNCOMMON IN YOUNG PATIENTS WITH RETINAL VEIN OCCLUSION

Purpose: To study the thrombotic factors, namely deficiencies of plasma proteins C, S, and antithrombin, factor V Leiden mutation, and positivity for antiphospholipid antibodies in young patients with retinal vein occlusion. Methods: The thrombophilia parameters listed above were analyzed from the laboratory records of 50 patients with the clinical diagnosis of retinal vein occlusion, aged less than 50 years. Results: A single prothrombotic factor was seen in 2 (4%) cases. The highest positivity was for the antiphospholipid antibodies (lupus anticoagulant in 6%, anticardiolipin antibodies in 2%, and anti-&bgr; 2 glycoprotein 1 in 10% cases). Other than one case where antiphospholipid syndrome was confirmed, these were transient. One patient had antithrombin deficiency. Protein C and protein S deficiency and factor V Leiden mutation were not seen in this group. Conclusion: Our data suggest that these thrombophilia risk factors are not commonly associated with retinal vein occlusion, and there is a need for studies on other factors that contribute to the development of this condition.
Stent malapposition and the risk of stent thrombosis: mechanistic insights from an in vitro model.

AIMS The aim of this report was to examine the effect of underexpansion on stent thrombogenicity with an in vitro perfusion model. METHODS AND RESULTS Drug-eluting stent (DES) samples were partially underdeployed in silicone tubes and perfused with porcine blood containing 10% anticoagulant citrate dextrose solution for four minutes at a flow rate of 200 ml/min. Thrombus formation was evaluated and compared between the well-apposed and malapposed sections. The malapposed sections showed significantly more thrombus formation compared to the well-apposed sections (13.9 vs. 0.41 mm2, p<0.001). CONCLUSIONS Stent malapposition has a very direct impact on thrombus formation. Optimised stent implantation is required to minimise malapposition in DES and BVS to reduce thrombus formation.
Sensitivity of Traditional and Risk-Based Glycemic Variability Measures to the Effect of Glucose-Lowering Treatment in Type 2 Diabetes Mellitus

Background: Here we assess associations between glycemic variability (GV) measures and outcomes from glucose-lowering therapy in patients with type 2 diabetes (T2DM) to identify the metrics most sensitive to treatment response. Methods: Data from 1699 patients in 6 previously reported studies in adults with T2DM treated with basal insulin and/or oral glucose-lowering drugs were included in a post hoc meta-analysis. Using 7-point blood glucose (BG) profiles we compared the GV metrics standard deviation (SD), mean amplitude of glycemic excursion (MAGE), mean absolute glucose (MAG), low and high BG risk indices (LBGI, HBGI), and average daily risk range (ADRR). Treatment-related changes in GV and risk status and associations between end-of-trial GV/risk metrics with treatment outcomes (end-of-trial glycated hemoglobin A1c[A1C] level ≥7.0%, hypoglycemia, and composite outcome of A1C <7.0% and no hypoglycemia), were evaluated. Results: Significant changes from baseline to end of treatment were observed in all measures (all P < .0001), with the largest reduction following treatment for HBGI (–65.5%) and ADRR (–43.3%). The baseline risk classification for hyperglycemia based on the risk categories of HBGI improved for 66.8%, remained unchanged for 29.8%, and deteriorated for 3.3% of patients (chi-square P < .0001), while the risk for hypoglycemia did not change. HBGI showed the strongest association with A1C ≥7.0% at the end of treatment, and LBGI showed the strongest association with symptomatic hypoglycemia. Conclusions: During glucose-lowering therapy in T2DM, HBGI and LBGI offer insights into hyperglycemia and trends toward hypoglycemia, respectively; ADRR may be the optimal GV measure responsive to hypo- and hyperglycemic treatment effects.
Particle‐based drop animation on meshes in real time

This paper presents a method for simulating the motion of water drops on a surface in real time. We describe the dynamics of a drop moving on the surface, and then we present our simulation model. We use a geometry‐based representation of a drop. Each drop is modeled by a deformable 3D mesh. This geometrical representation allows drops to be on the surface or in the air. We also propose a simple method to handle drop merging and separation. For the rendering, we simulate reflection and refraction. The drop trace is also taken into account. Our method is fast and robust and yields realistic results when applied to treat condensation on a surface or human sweating in real time. Copyright © 2012 John Wiley & Sons, Ltd.
A novel sugar analog enhances sialic acid production and biotherapeutic sialylation in CHO cells

A desirable feature of many therapeutic glycoprotein production processes is to maximize the final sialic acid content. In this study, the effect of applying a novel chemical analog of the sialic acid precursor N‐acetylmannosamine (ManNAc) on the sialic acid content of cellular proteins and a model recombinant glycoprotein, erythropoietin (EPO), was investigated in CHO‐K1 cells. By introducing the 1,3,4‐O‐Bu3ManNAc analog at 200–300 µM into cell culture media, the intracellular sialic acid content of EPO‐expressing cells increased ∼8‐fold over untreated controls while the level of cellular sialylated glycoconjugates increased significantly as well. For example, addition of 200–300 µM 1,3,4‐O‐Bu3ManNAc resulted in >40% increase in final sialic acid content of recombinant EPO, while natural ManNAc at ∼100 times higher concentration of 20 mM produced a less profound change in EPO sialylation. Collectively, these results indicate that butyrate‐derivatization of ManNAc improves the capacity of cells to incorporate exogenous ManNAc into the sialic acid biosynthetic pathway and thereby increase sialylation of recombinant EPO and other glycoproteins. This study establishes 1,3,4‐O‐Bu3ManNAc as a novel chemical supplement to improve glycoprotein quality and sialylation levels at concentrations orders of magnitude lower than alternative approaches.

On the prediction of claim duration for income protection insurance policyholders

Abstract This paper explores how we can apply various modern data mining techniques to better understand Australian Income Protection Insurance (IPI). We provide a fast and objective method of scoring claims into different portfolios using available rating factors. Results from fitting several prediction models are compared based on not only the conventional loss prediction error function, but also a modified loss function. We demonstrate that the prediction power of all the data mining methods under consideration is clearly evident using a misclassification plot. We also point out that this predictability can be masked by looking at just the conventional prediction error function. We then suggest using the stepwise regression technique to reduce the number of variables used in the data mining methods. Apart from this variable selection method, we also look at principal components analysis to increase understanding of the rating factors that drive claim durations of insured lives. We also discuss and compare how different variable combining techniques can be used to weight available predicting variables. One interesting outcome we discover is that principal components analysis and the weighted combination prediction model together provide very consistent results on identifying the most significant variables for explaining claim durations.
Boundary conditions for high-shear grain flows

Boundary conditions are developed for rapid granular flows in which the rheology is dominated by grain–grain collisions. These conditions are $\overline{v}_0 = {\rm const}\,{\rm d}\overline{v}_0/{\rm d}y$ and u0 = const du0/dy, where $\overline{v}$ and u are the thermal (fluctuation) and flow velocities respectively, and the subscript indicates that these quantities and their derivatives are to be evaluated at the wall These boundary conditions are derived from the nature of individual grain–wall collisions, so that the proportionality constants involve the appropriate coefficient of restitution ew for the thermal velocity equation, and the fraction of diffuse (i.e. non-specular) collisions in the case of the flow-velocity equation. Direct application of these boundary conditions to the problem of Couette-flow shows that as long as the channel width h is very large compared with a grain diameter d it is permissible to set $\overline{v} = 0$ at the wall and to adopt the no-slip condition. Exceptions occur where d/h is not very small, when the wall is not rough, and when the grain–wall collisions are very elastic. Similar insight into other flows can be obtained qualitatively by a dimensional analysis treatment of the boundary conditions. Finally, the more difficult problem of self-bounding fluids is discussed qualitatively.
Corporate Social Responsibility Among Saudi Arabian Firms: An Empirical Investigation

There is an increasing recognition within the developed economies across the world that today, CSR is not an optional extra; i.e., firms can no longer look at CSR as a luxury or an indicator of their goodwill toward society. Firms, in today’s context, are seeking to integrate CSR in their corporate policies and strategies. Developing countries’ firms, however, are still in the early stage of their awareness and integration of CSR activities within their corporate policies and strategies. The present exploratory study utilizes a sample of Saudi Arabian firms’ managers to assess the extent of their awareness of CSR, its role within their organizations, the extent of CSR integration in their corporate policies, and the nature and scope of these firms’ CSR activities. Results indicate that there is a reasonable level of CSR awareness as well as a moderately positive attitude toward the concept. However, most CSR activities in Saudi Arabia seem to focus on the local communities in which these firms operate. Discussion of the results and their implications are provided.
Tuberculosis as a Major Global Health Problem in the 21st Century: A WHO Perspective

The World Health Organization, the Global Partnership to Stop TB, and the Millenium Development Project have all adopted the following 2005 targets for tuberculosis control: to detect at least 70% of all estimated sputum smear-positive cases and to treat successfully at least 85% of them. Although implementation of the DOTS strategy is the foundation for proper tuberculosis control, basic DOTS implementation may not be enough to reach these targets. Instead, evidence from several countries indicates that, although cure rates are approaching the global target, the case detection target may not be met, even with 100% DOTS implementation in designated public facilities. Thus, tuberculosis control must be critically examined to foster higher performance. In the context of an expanded framework for tuberculosis control, we present four strategic interventions through which cure and case detection rates may be significantly improved: (1) wider involvement of community workers, (2) engagement of private practitioners, (3) proper management of drug-resistant tuberculosis, and (4) efforts focused on controlling tuberculosis and human immunodeficiency virus. We conclude that, although country-based estimates need further refinement to ascertain the impact of each intervention, a fundamental shift in the approach to tuberculosis control is required if the global targets are to be reached rapidly.
Subsidiary Staffing in Multinational Enterprises: Agency, Resources, and Performance

How likely are multinational enterprises (MNEs) to use expatriate parent country nationals to staff culturally distant subsidiaries? How does their employment affect subsidiary performance? The agency theory prediction is that MNEs will rely more heavily on parent country nationals as cultural distance increases and that this reliance will weaken over time. Both agency theory and the “resource-based view” suggest that a positive effect of expatriate staffing on subsidiary performance increases with cultural distance but decreases over time. Results largely supported the predictions in data on Japanese foreign subsidiaries.
Born effective charges and infrared response of LiBC

Calculations of the zone-center optical-mode frequencies (including LO-TO splitting), Born effective charges ${Z}_{\ensuremath{\alpha}\ensuremath{\alpha}}^{*}$ for each atom, dielectric constants ${\ensuremath{\epsilon}}_{0}$ and ${\ensuremath{\epsilon}}_{\ensuremath{\infty}},$ and the dielectric response in the infrared, using density functional linear response theory, are reported. Calculated Raman modes are in excellent agreement with experimental values $(170{\mathrm{cm}}^{\ensuremath{-}1}$ and $1170{\mathrm{cm}}^{\ensuremath{-}1}),$ while it will require better experimental data to clarify the infrared-active mode frequencies. The Born effective charges ${Z}_{\ensuremath{\alpha}\ensuremath{\alpha}}^{*}$ (i) have surprisingly different values for B and C and (ii) show considerable anisotropy. Relationships between the effective charges and LO-TO splitting are discussed, and the predicted reflectivity in the range $0\char21{}1400{\mathrm{cm}}^{\ensuremath{-}1}$ is presented. These results hold possible implications for Li removal in LiBC and C substition for B in ${\mathrm{MgB}}_{2}. $
Service Quality : A Mediator of Customer Complaint Behaviour and Customer Loyalty

Aims to examine the mediating role of service quality in customer complaint behaviour and customer loyalty. Adopts a quantitative cross-sectional research design and uses the MedGraph program, Sobel tests and the Baron and Kenny method to test for mediation effect of service quality on the relationship between customer complaint behaviour and customer loyalty. Service quality is a significant mediator in the relationship between customer complaint behaviour and customer loyalty of Ugandan mobile phone subscribers. Adding service quality to the relationship boosts the relationship between customer complaint behaviour and customer loyalty by 45 percent among the mobile phone subscribers studied. The findings therefore suggest that when service quality is low, a high level of customer loyalty may not be attained among mobile phone subscribers. Future research should use quantitative and a qualitative approach. Only cross-sectional used. A longitudinal study may therefore be useful in future to investigate the mediating impact of service quality over a longer period of time. Managers, policymakers, and mobile telephone companies should advocate and strive for improvements across all dimensions of service quality to boost the loyalty of cell phone customers. While substantial body of research has been carried out on customer complaint behaviour, our paper is the first to test the mediating role of service quality in the relationship between customer complaint behaviour and customer loyalty among mobile phone subscribers in a developing nation context. Contributes to the positive significant influence of service quality in enhancing the level of customer loyalty based on customer complaint behaviour.
