Security of Photo Sharing on Online Social Networks

: Photo sharing is an attractive feature in Online Social Networks (OSNs) but it may leak users privacy if they are allowed to post, comment, and tag a photo freely. This issue of sharing the photos of individual or himself/herself is addressed by the proposed scheme. The proposed scheme is used to prevent possible privacy leakage of a photo. For this purpose, an efficient facial recognition (FR) system is required that can recognize everyone in the photo. However, to train the FR system, more demanding privacy setting may limit the number of the photos that are publicly available. To solve this problem, the proposed scheme attempts to utilize users private photos by designing a personalized FR system and also provide security while posting the photo. A distributed consensus based method is also developed to reduce the computational complexity and protect the private training set. The efficiency of proposed scheme is calculated by using recognition ratio. The proposed mechanism is implemented as a proof of concept on Android application in OSN’s (Online Social Networks) on Facebook platform.
Ocular Status of Commercial Drivers in a Nigerian Community

Aim: This study aimed at determining the ocular status of commercial intercity drivers. Methods: This descriptive study was conducted at Owo, South West Nigeria among commercial intercity drivers between June and September, 2009. Ethical clearance was obtained from the Ethical Review Committee of Federal Medical Centre, Owo, Ondo State, Nigeria prior to commencement of this study. Informed consent was obtained from each of the respondents. Chi-square test was done to determine if there was a statistically significant difference between the study parameters. Results: Ninety respondents were enrolled in this study. The driving experience of the respondents revealed that most respondents (58.9%) had more than 20 years driving experience. Few respondents (2.2%) had visual impairment in the better eye. None of the respondents had colour vision defect. Most respondents: 66(73.3%) did not have eye test at the time they obtained drivers’ licence. Majority of the respondents: 54(60%) did not have ocular morbidity. The visual acuity in the better eye and second eye was not significantly associated with involvement in Road Traffic Accident with a p value of 1.2 and 0.14 respectively. Conclusion: Few respondents had ocular morbidity and the prevalence of visual impairment in the better eye was very low. Most respondents did not have ocular examination at the time they were issued drivers’ licence thus it should be introduced as part of the compulsory test process for issuing and renewing drivers license in Nigeria. *Corresponding author: Dr. Charles Oluwole Omolase, Department of Ophthalmology, Federal Medical Centre, Owo, Ondo State, Nigeria, Tel. +234-08033788860; E-mail: omolash2000@yahoo.com Received March 12, 2012; Accepted April 09, 2012; Published April 11, 2012 Citation: Omolase CO, Afolabi OT, Omolase BO, Ihemedu CO (2012) Ocular Status of Commercial Drivers in a Nigerian Community.

Adiponectin receptor: A Potential Target For Diabetes, Obesity And Other Disorders

Summary Adipose tissue acts as an endocrine organ producing a number of substances with an important role in the regulation of food consumption, energy expenditure and a variety of metabolic processes. Adiponectin is a collagen-like plasma protein secreted by adipocytes that has been recommended to play a substantial role in the development of insulin resistance and obesity. A number of studies have shown that obesity, insulin resistance and atherosclerosis are associated with decreased level of adiponectin and its replacement during experimentation is able to diminish insulin resistance, increases insulin sensitivity and reduces lipids and atherogenesis. Chronic and central adiponectin treatment reduces weight, glucose and lipids. Adiponectin is exclusively secreted from adipose tissue into the bloodstream and is very abundant in plasma relative to many hormones. Previous findings showed that its level is decreasing in person with increasing body mass index. The adiponectin receptors, AdipoR1 and AdipoR2, which regulate the antidiabetic actions of adiponectin, have been cloned and are down regulated in obesitylinked insulin resistance. Up regulation of adiponectin is a partial cause of the insulin- sensitizing and antidiabetic actions of thiazolidinediones. Therefore, adiponectin and adiponectin receptors represent potential versatile therapeutic targets to combat obesity-linked diseases characterized by insulin resistance. The aim of this review is to recapitulate the current knowledge about the physiology and pathophysiology of adiponectin and evaluation of adiponectin receptor as a target of diabetes (insulin resistance), obesity and atherosclerosis and asthma.
Fair value accounting, financial economics and the transformation of reliability

Abstract This paper addresses the question of how and why the use of fair values in accounting acquired significance prior to 2007 despite widespread opposition. An answer is suggested in terms of four mutually supporting conditions of possibility which gave the proponents of fair value institutional support and strength which their opponents lacked. First, fair value enthusiasts could draw on the background cultural authority of financial economics. Second, the problem of accounting for derivatives provided a platform and catalyst for demands to expand the use of fair values to all financial instruments. Third, the transformation of the balance sheet by conceptual framework projects from a legal to an economic institution created a demand for asset and liability numbers to be economically meaningful, a demand which fair value could claim to satisfy. Fourth, fair value became important to the development of a professional, regulatory identity for standard‐setters. These four conditions, though not sufficient in themselves, added up to a weakening of a transactions‐based, realization‐focused conception of accounting reliability in favour of one aligned with markets and valuation models. An interesting consequence is that auditing standard‐setters found themselves forced into a reactive role.

Methods and Material: 19 benzo[d]-5-(1-Benzyl-1H-[1,2,3]triazol-4-yl)-4phenyl-4H-[1,2,4]triazole-3-thiol derivatives were synthesized and evaluated for their bioactivities in vitro as anti-inflammatory agents. Statistical analysis used: Statistical analysis was performed by one-way analysis of variance (ANOVA) followed by a least signifcant difference (LSD) test for multiple comparisons, using SPSS version 17.0 statistical software. Results: The results of this study indicated that compound 17(1-Benzyl-4-[5-(4-chloro-phenylsulfanyl)-4-phenyl-4H-[1,2,4]triazol-3-yl]-1H-[1,2,3] triazole) showed excellent inhibition on the expression of IL-6 among these compounds in LPS-induced RAW 264.7 macrophage cell. Conclusion: The findings of this study showed that compound 17 showed excellent inhibition on the expression of IL-6 in LPSinduced macrophage cells. Further studies are warranted to investigate the mechanism of anti-inflammation, in order to represent a novel strategy for the modulation of inflammatory responses.
ighly selective H 2 O 2 sensor based on 1-D nanoporous Pt @ C hybrids ith core – shell structure

A strategy of sacrificial template was put forward to prepare porous Pt nanowires core with carbon shell (Pt PNW@C) using Te nanowires as template. These Pt PNW@C hybrids show a highly sensitive response to H2O2 oxidation recorded by chronoamperometry at 0.2 V vs. the saturated calomel electrode (SCE). Under optimal conditions, this H2O2 transducer displays a linear range of 0.01–1.2 M with a sensitive of 6.28 A M−1 cm−2 (r = 0.9997), and a detection limit of 0.002 M (signal/noise = 3). Moreover, the
Center of genetic diversity and dissemination pathway in adzuki bean deduced from seed protein electrophoresis

Genetic diversity center plays important roles in collection of germplasm resources. To better understand the genetic diversity of adzuki bean (Vigna angularis L.), seed protein of 198 local strains collected from throughout China and Japan were analyzed by SDS-polyacrylamide gel electrophoresis. Four protein types were identified and the frequency of each protein type strain showed a clear geographical cline. The pattern of geographical distribution of the protein types reflected the region of genetic diversity, and the dissemination pathway in adzuki bean was proposed. The region of genetic diversity center in seed protein was southwestern China. Adzuki bean might have spread via middle and east of China to northern China and Japan from southwestern China, as only one seed protein type was detected in Japanese strains in this study. These results provide fundamental and important clues for genetic diversity preservation and exploitation of adzuki bean germplasm resources.
Estimating aboveground biomass for Norway spruce (Picea abies) in Iceland

Forest carbon sinks were included in the Kyoto Protocol as an option for mitigating climate change, since these sinks are known to play an important role in the global GHG balance. Therefore all countries that have ratified the Kyoto Protocol need to deliver estimates of forest area and carbon stocks to UNFCCC. This work presents the results of a study of Norway spruce in Iceland. The aim was to compare two methods to estimate forest biomass and carbon stocks, either directly with biomass equations or indirectly from stem volume, basic density and biomass expansion factors (BEFs). Basic wood density of Norway spruce was significantly related to tree size (P<0.002), but BEF showed no such relation. The two methods gave significantly different estimates for stem biomass, with the direct allometric method giving better results when compared to real values. There was, however, no significant difference between the two methods when total aboveground biomass was estimated. The direct allometric method will therefore be used to estimate the carbon stock of Norway spruce stands in Iceland, since it involves fewer parameters than the BEF method.
Selling through Priceline? On the impact of name-your-own-price in competitive market

ABSTRACT Priceline.com patented the innovative pricing strategy, Name-Your-Own-Price (NYOP), that sells opaque products through customer-driven pricing. In this article, we study how competitive sellers with substitutable, non-replenishable goods may sell their products (i) as regular goods, through a direct channel at posted prices, and possibly at the same time (ii) as opaque goods, through a third-party channel that engages in NYOP. We establish a stylized model framework that incorporates three sets of stakeholders: two competing sellers, an intermediary NYOP firm, and a sequence of customers. We first characterize customers’ optimal purchasing/bidding decisions under various channel structures and then analyze corresponding sellers’ dynamic pricing equilibrium. We conduct extensive numerical studies to illustrate the impact of inventory and time on equilibrium prices, expected profit, and channel strategies. We find that the implications are highly dependent on channel structure (dual versus single). In particular, more inventory may reduce one’s expected profit under the dual structure, whereas this never happens when a seller only uses the direct channel. Interestingly, although competing sellers seldom benefit from the existence of NYOP channels, it is possible that one or both of the sellers adopt it in equilibrium. We identify timing, inventory levels, and channel opaqueness as key drivers for NYOP adoption and characterize equilibrium areas for each type of channel structure.
Financial Liberalization and Macroeconomic Performance: Empirical Evidence from Pakistan

This paper attempts to examine the impact of financial sector liberalization on macroeconomic performance in Pakistan by using time series econometric analysis over the period 1972-2006. The study undertakes bivariate and multi-variate models for empirical analysis. In Pakistan, financial sector liberalization was started with the reforms of macroeconomic structural adjustment programs especially by the end of 1980s. The results suggest that there is significant positive impact of financial liberalization variables on economic growth and investment. The findings of this study also reveal that there exists long-run and short-run relationship between the indicators of financial liberalization and economic growth and investment in Pakistan. The results are also consistent with some of the previous studies as described in the literature. Finally, it is concluded that there is an ardent need to stabilize the performance of financial system in Pakistan through political stability and good governance by taking some extra measures. The Strengthening of the State Bank‟s capacity for supervision and prudential regulations is necessary.

Modeling Intonation in Non-Western Musical Cultures

Musical cultures around the world use tuning systems very different from the tuning system used in Western music. Comparing and contrasting intonation from various cultures could give insight into the question of learned versus innate preferences in the perception of music, and into the cultural development of musical traditions. However, methods for analyzing intonation in Western music have not been generalized to non-Western contexts. Flexible and non-discrete tuning used in cultures such as Arabic maqam music pose a chal-lenge for analyzing intonation. This paper attempts to generalize Stolzenburg’s “Periodicity” method and Gill and Purves’ “Similarity” method for microtonal music, and finds that they are ill-suited for the analysis of Arabic music. An alternative approach is developed, which analyzes the relative intonation of a series of consecutive notes. This approach reveals that Arabic intonation is fundamentally different from Western and Chinese intonation. While Chinese and Western intonation are based on intervals from a fixed scale, Arabic intonation is based on a continuous spectrum of small intervals.
Quantitative Performance Prediction Modeling for FTLs

Recently, various flash translation layers(FTL) have been studied and introduced to improve the performance of SSDs by mitigate unique characteristics of NAND flash memories which is the main data storage of SSDs. However, evaluation of FTLs has been totally based on simulation that requires actual implementation of the corresponding FTL algorithm. Therefore, in this paper, we proposed the modeling method that predict performance of FTLs easily and fast. We may know quantitative performance of FTL simply and accurately by parameterization of FTL and input logical access patterns. By comparison to real simulation results, we prove that our modeling method shows very simple and accurate prediction results with only 12% of error.
Role of Notch, SDF-1 and Mononuclear Cells Recruitment in Angiogenesis

Intussusceptive angiogenesis (IA) known also as splitting angiogenesis is a recently described mechanism of vascular growth alternative to sprouting. It plays an essential role in the vascular remodeling and adaptation of vessels during normal and pathological angiogenesis. It is an “escape” mechanism during and after irradiation and anti-VEGF therapy, both inducing angiogenic switch from sprouting to IA by formation of multiple transluminal tissue pillars. Our recently published data revealed the significant induction of IA after inhibition of Notch signaling associated with an increased capillary density by more than 50%. The induced IA was accompanied by detachment of pericytes from basement membrane, increased vessel permeability and recruitment of mononuclear cells toward the pillars; the process was dramatically enhanced after injection of bone marrow-derived mononuclear cells. The extravasation of mononuclear cells with eventual bone marrow origin was associated with upregulation of chemotaxis factors SDF-1 and CXCR4. In addition, SDF-1 expression was upregulated in the endothelium of liver sinusoids in Notch1 knockout mouse, together with vascular remodeling by intussusception. In this chapter, we discuss this important mechanism of angiogenesis, as well as the role of Notch signaling, SDF-1 signaling and mononuclear cells in the complex process of angiogenesis.
CALL in the Year 2000: Still developing the research agenda

In this commentary I would like to address several aspects of the proposal for a research agenda for CALL advanced by Chapelle (1997). The explicit aim of Chapelle's article is the identification of "key questions about CALL" as well as "effective research methods to be used to answer them" (p. 19). Chapelle raises a number of interesting points that will prove helpful for the design of future studies. I believe, however, that some points of her argument deserve greater emphasis whereas others could benefit from a more comprehensive analysis. The five areas of improvement identified in this commentary are (a) the literature review on research perspectives of classroom discourse needs to be further expanded, (b) research domains other than discourse analysis may also be relevant for the analysis of the pedagogical effectiveness of CALL, (c) the theoretical analysis of the psycholinguistic process of L2 development needs to be specified in further detail, (d) the analysis of electronic and face-to-face communication does not take into account relevant differences brought about by distinct communication media, and (e) the relative importance of computer mediated communication (CMC) in the proposed research agenda appears to deserve greater emphasis given the current level of interactivity achieved by various communication media.
Layer-by-layer self-assembled metal-ion- (Ag-, Co-, Ni-, and Pd-) doped TiO 2 nanoparticles: synthesis, characterisation, and visible light degradation of Rhodamine B

Metal-ion- (Ag, Co, Ni and Pd) doped titania nanocatalysts were successfully deposited on glass slides by layer-by-layer (LbL) selfassembly technique using a poly(styrene sulfonate sodium salt) (PSS) and poly(allylamine hydrochloride) (PAH) polyelectrolyte system. Solid diffuse reflectance (SDR) studies showed a linear increase in absorbance at 416 nm with increase in the number of m-TiO 2 thin films. The LbL assembled thin films were tested for their photocatalytic activity through the degradation of Rhodamine B under visible-light illumination. From the scanning electron microscope (SEM), the thin films had a porous morphology and the atomic force microscope (AFM) studies showed "rough" surfaces. The porous and rough surface morphology resulted in high surface areas hence the high photocatalytic degradation (up to 97% over a 6.5 h irradiation period) using visible-light observed. Increasing the number of multilayers deposited on the glass slides resulted in increased film thickness and an increased rate of photodegradation due to increase in the availability of more nanocatalysts (more sites for photodegradation). The LbL assembled thin films had strong adhesion properties which made them highly stable thus displaying the same efficiencies after five (5) reusability cycles.
ILLUMINANCE DURING A SOLAR ECLIPSE WITH LIMB DARKENING: A MATHEMATICAL MODEL

We present a mathematical model that predicts the variation of illuminance during a solar eclipse, considering continuous effects of limb darkening. We assume that (1) the Sun and the Moon constitute perfect spheres, (2) the Moon crosses the Sun with a constant apparent velocity, and (3) sunspots, prominences, and coronae can be neglected. We compare predictions of this model with actual measurements made by Mollmann & Vollmer (2006) during a total solar eclipse in Turkey, and with predictions of existing models. The new model is shown to describe the actual phenomenon more accurately than existing models.
Turning mental expressions’ reference into neural flexible activations

In this paper, I intend to justify a positive approach to social neuroscience that takes into consideration restrictive philosophical arguments about our—common and scientific—use of mental concepts. I will start with a clarification of the philosophical point of view, which holds that it is impossible to identify others’ mental states as neural states because the language we use to speak about others’ mental states—and our own, too—is a public language. Second, I will show the gap between explanations of social linguistic communication of intentions and reasons for acting and neurological explanations of the human mind. Third, I will use M. D. Lieberman’s (2007) Internal/External Reference dichotomy to question whether recent findings in the social neurosciences confirm that many folk psychological concepts refer to external social events rather than internal states. If this is the case, neuroscientific findings show that part of the psychological language use is fundamentally behavioristic, i.e., not about neural states, but about social actions (see Suzanne Oosterwijk et al., 2015). These actions obviously include bodily and neurological processes, but they are not defined by these. Therefore, if all this is true, neuroscientists are right to be confident that neuroscience can help us to investigate social interactions, but certainly not in a reductive mannerthat is, not by reducing socially used concepts, such as the concept of “intending” to do something, to neural activities; instead, neuroscience can help to establish new and more precise classifications of social behaviors, that have, among their parts, scientifically identifiable flexible neural processes.
