Developing a Viral Artifact to Improve Employees’ Security Behavior

According to the scientific information management literature, the improper use of information technology (e.g. personal computers) by employees are one main cause for operational and information security loss events. Therefore, organizations implement information security awareness programs to increase employees’ awareness to further prevention of loss events. However, in many cases these information security awareness programs consist of conventional delivery methods like posters, leaflets, or internal messages to make employees aware of information security policies. We assume that a viral information security awareness video might be more effective medium than conventional methods commonly used by organizations. The purpose of this research is to develop a viral video artifact to improve employee security behavior concerning information technology. Keywords—Information Security Awareness, Delivery Methods, Viral Videos, Employee Security Behavior.
The Dynamic Nature of Customers’ Criteria For Assessing Customer Value: a Longitudinal Investigation

Priester and Petty (2001) found that whether the important other was liked or disliked affected the impact of interpersonal discrepancy on the resulting subjective ambivalence. An increase in interpersonal discrepancy heightened subjective ambivalence only when the important other was liked. It is possible that not only will high self monitors show increases in subjective ambivalence in the presence of interpersonal discrepancy with liked others, but they may also show increases in subjective ambivalence when there is an absence of interpersonal discrepancy with disliked others. A plausible rationale for this proposition is that high self-monitors are more attuned to social status and hierarchy than low self-monitors (Gangestad and Snyder 2000). For this reason, when forming attitudes and judgments, high self-monitors may care not so much about their own liking/disliking of the other person as about the other person’s low/high social status. We are currently conducting an experiment to investigate this proposition. Overall, this research offers guidance for promising new research directions, with the long-term perspective of constructing a comprehensive framework of the formation of attitudinal ambivalence towards products, services, and brands.
Signaling events in pathogen-induced macrophage foam cell formation.

Macrophage foam cell formation is a key event in atherosclerosis. Several triggers induce low-density lipoprotein (LDL) uptake by macrophages to create foam cells, including infections with Porphyromonas gingivalis and Chlamydia pneumoniae, two pathogens that have been linked to atherosclerosis. While gene regulation during foam cell formation has been examined, comparative investigations to identify shared and specific pathogen-elicited molecular events relevant to foam cell formation are not well documented. We infected mouse bone marrow-derived macrophages with P. gingivalis or C. pneumoniae in the presence of LDL to induce foam cell formation, and examined gene expression using an atherosclerosis pathway targeted plate array. We found over 30 genes were significantly induced in response to both pathogens, including PPAR family members that are broadly important in atherosclerosis and matrix remodeling genes that may play a role in plaque development and stability. Six genes mainly involved in lipid transport were significantly downregulated. The response overall was remarkably similar and few genes were regulated in a pathogen-specific manner. Despite very divergent lifestyles, P. gingivalis and C. pneumoniae activate similar gene expression profiles during foam cell formation that may ultimately serve as targets for modulating infection-elicited foam cell burden, and progression of atherosclerosis.
Influence of culture pH on the content and composition of teichoic acids in the walls of Bacillus subtilis.

SUMMARY: Teichoic acids were invariably present in the walls of Bacillus subtilis var. niger and B. subtilis W23 grown in chemostats at D = 0.25 h-1, 35 °C, pH 7.0 in media containing non-limiting concentrations of phosphate, but they possessed little ester-bound alanine. However, varying the culture pH between 8.0 and 5.0 effected changes not only in the amount but also in the ester-bound alanine content of wall teichoic acids of both organisms. The walls of phosphate-limited B. subtilis var. niger were devoid of teichoic acid when grown at pH 7.0, but not at lower pH, when this polymer again contained ester-bound alanine. The magnesium binding properties of these wall preparations were also determined. The results showed that walls containing ester-bound alanine in the teichoic acid bound the same amount of magnesium as walls in which the teichoic acid was unsubstituted by alanine.
Murine model for skeletal metastases of Ewing's sarcoma

Ewing's sarcoma shows a strong tendency to metastasize to the lungs or the skeleton, or both. A peculiar feature of the secondary involvement of bone with this tumor is that it may also appear in the absence of clinically evident lung metastases, both at clinical presentation and during the course of the disease. Although osseous metastases are critically relevant for prognosis, the pathogenesis of this peculiar feature of Ewing's sarcoma is poorly understood, partly due to the lack of appropriate experimental in vivo models. We show that the intravenous injection of TC‐71 Ewing's sarcoma cells into athymic 4–5‐week‐old Crl/nu/nu (CD‐1) BR mice reproducibly colonizes specific sites of the skeleton in addition to the lungs and lymph nodes. The distribution and the morphologic appearance of these experimental bone metastases mimic the pattern of skeletal involvement observed in humans. This experimental model of bone metastasis of Ewing's sarcoma.
Report of the American Heart Association Task Force on the Future of Cardiopulmonary Resuscitation.

T he American Heart Association Task Force on the Future of Cardiopulmonary Resuscitation was formed to devise long-range (5-10-year) strategies to improve the survival rate of victims of sudden cardiac arrest, with emphasis on cardiopulmonary resuscitation (CPR). The main considerations of the task force initially and throughout its deliberations were 1. The failure of current CPR strategies to save lives in many communities in this country. Even in large American cities, few lives are saved despite prehospital emergency care programs. The final measure of the success of any program must be the survival rate, without neurological deficit, of cardiac arrest victimsnot the number of persons trained in CPR or other measures. 2. The clear value of rapid defibrillation in improving the survival rates of cardiac arrest victims as well as the development of automatic external defibrillators that can be used safely by lay persons with minimal training. 3. The apparent increasing resistance to performance of CPR because of the perceived risk of infectious disease to the rescuer. The task force was asked to 1. Predict what optimal CPR may be in the community setting in 5-10 years and how automatic defibrillation may affect procedures 2. Define the likely implications for instruction if CPR procedures change 3. Identify areas of needed research 4. Identify how changes in CPR procedures may be brought about 5. Define the role the AHA should play in research, device availability and design, and the process of change 6. Identify AHA polices that warrant change
Driving under low-contrast visibility conditions in Parkinson disease

Objective: To assess driving performance in Parkinson disease (PD) under low-contrast visibility conditions. Methods: Licensed, active drivers with mild to moderate PD (n = 67, aged 66.2 ± 9.0 years, median Hoehn–Yahr stage = 2) and controls (n = 51, aged 64.0 ± 7.2 years) drove in a driving simulator under high- (clear sky) and low-contrast visibility (fog) conditions, leading up to an intersection where an incurring vehicle posed a crash risk in fog. Results: Drivers with PD had higher SD of lateral position (SDLP) and lane violation counts (LVC) than controls during fog (p < 0.001). Transition from high- to low-contrast visibility condition increased SDLP and LVC more in PD than in controls (p < 0.01). A larger proportion of drivers with PD crashed at the intersection in fog (76.1% vs 37.3%, p < 0.0001). The time to first reaction in response to incursion was longer in drivers with PD compared with controls (median 2.5 vs 2.0 seconds, p < 0.0001). Within the PD group, the strongest predictors of poor driving outcomes under low-contrast visibility conditions were worse scores on measures of visual processing speed and attention, motion perception, contrast sensitivity, visuospatial construction, motor speed, and activities of daily living score. Conclusions: During driving simulation under low-contrast visibility conditions, drivers with Parkinson disease (PD) had poorer vehicle control and were at higher risk for crashes, which were primarily predicted by decreased visual perception and cognition; motor dysfunction also contributed. Our results suggest that drivers with PD may be at risk for unsafe driving in low-contrast visibility conditions such as during fog or twilight.
High-rate turbo code design for block-fading channels

In this work, we propose the construction of turbo codes for high rate transmission over block-fading channels. These codes are suitable for modern standards such as the 3GPP-LTE, in which high data rates are required. Our designs are based on channel multiplexing schemes initially developed for block fading channels, namely horizontal multiplexing and h-n-diagonal multiplexing. However, to attain the maximum diversity order provided by the channel for high-coding rates, a single parity-check code is needed in the overall code construction. Word error rate performance is compared to Gaussian and discrete outage probabilities using Monte Carlo simulations.
Suicidal risk during controlled clinical investigations of fluvoxamine.

BACKGROUND Suicide is a serious risk factor in major depressive disorder. Paradoxical emergence of suicidal ideation or behavior during antidepressant treatment has been reported in isolated cases. An evaluation was undertaken to assess the risk of suicidality during treatment with fluvoxamine, a serotonin selective reuptake inhibitor. METHOD Meta-analyses were conducted on pooled data from double-blind, randomized, placebo-controlled, parallel-group clinical trials. The primary outcome measure was the suicide item of the Hamilton Rating Scale for Depression. Tests for emergence of substantial suicidal ideation and improvement or worsening in suicidal ideation were performed using the Mantel-Haenszel adjusted incidence difference. The Breslow-Day test was used to test for lack of homogeneity across trials. Secondary analysis, which consisted of Pearson's chi-square test, was used to confirm the Mantel-Haenszel result. RESULTS In comparison to placebo, fluvoxamine was associated with significantly greater improvement in suicidal ideation (p = .01) and significantly less worsening of suicidal ideation (p < .01). No differences were found in the emergence of substantial suicidal ideation. CONCLUSION These findings demonstrate that fluvoxamine is not associated with an increased risk of emergence of substantial suicidal thoughts among depressed patients. On the contrary, the results are suggestive of a protective effect of fluvoxamine upon the risk of suicidal ideation.

ABSTRACT The results of the Focus Simplexa FluA/B & RSV Direct assay were compared to those of laboratory-developed reverse transcription PCR tests for 498 nasopharyngeal swabs. Concordance rates were 96.6% (476/493; κ = 0.91), 97.6% (481/493; κ = 0.47), and 99.2% (488/492; κ = 0.94) for influenza A, influenza B, and respiratory syncytial virus, respectively.
Trace Based Semi-Blind and Blind Spectrum Sensing Schemes for Cognitive Radio

To make full use of the correlations among the received signal samples, new spectrum sensing schemes based on trace of noise sample covariance matrix are introduced. The new schemes utilize the fact, the statistical covariance matrices of received signal samples and noise samples are different with high probability, to detect whether the primary signal exists or not. Both of them can execute spectrum sensing without the information about primary signal and communication channel. Furthermore, to eliminate the negative effect of noise uncertainty, we modify the proposed model to adapt the case when the noise variance is completely unavailable. In addition, an optimal trace based semi-blind sensing scheme by maximizing the received signal-to-noise ratio (SNR) is also demonstrated. Multivariate statistical theories are used to derive the theoretical decision thresholds. Simulation results verify the effectiveness of the proposed schemes.
The Relationship of PM Variation to Visibility and Mixing Layer Height under Haze / Fog Condition in Multi-Cities of Northeast China

The variations of visibility, PM mass concentration and mixing layer height (MLH) at four major urban-industry regions (Shenyang, Anshan, Benxi and Fushun) in multi-cities of central Liaoning over northeast China were evaluated from 2009-2012 to characterize the dynamics effect on air pollution. The annual mean visibilities were about 13.7±7.8km, 13.5±6.5km, 12.8±6.1km and 11.5±6.8km in Shenyang, Anshan, Benxi and Fushun, respectively. The pollution load (PM×MLH) shown a weaker vertical diffusion in Anshan with a higher PM concentration in the near-surface. High concentrations of fine mode particles may be partially attributed to the biomass burning emissions from September in Liaoning Province and surrounding regions in Northeast China as well as the coal burning during the heating period with lower MLH in winter. The increasing wind speed has a similar change as the increasing of mixing layer height to make the effect on the aerosol vertical diffusion. The visibility on the non haze-fog days was about 2.5-3.0 times higher than that on hazy and fog days. The fine particle concentrations of PM2.5 and PM1.0 on the haze and fog days were ~1.8-1.9 times and ~1.5 times higher than that on no hazy-fog days. The MLH during fog pollution showed more declining trend than haze pollution compared with non haze-fog days. The results of this study could provide the useful information to better recognize the effects of vertical pollutants diffusion on air quality in the multi-cities of central Liaoning over Northeast China.

Access Control Policy on Mobile Operating System Frameworks –A survey

Background: Access control is the method of granting permissions according to policies. Mobile devices, such as Smartphone, are acting as multi-purpose devices for private as well as the corporate environment. Since the applications in the Smartphone are accessing in various contexts, there would be a leakage of data and applications. Furthermore, when third party apps are downloading on Android-based platforms, it causes threats to the existing system applications. So, different access control policies have been implemented in the Android-based Smartphone to separate the own application and corporate application for providing security. Methods: This paper presents a survey of access control models in various frameworks and compares them by their performance evaluations. The performance of each framework is corresponding to the characteristics of access control policies. These access controls are categorizing according to role, discretionary, mandatory, context, and attributes. Finding: We have found that, Context-Based Access Control (CBAC) and Dynamic Role Based Access Control (DRBAC) are providing better performance. Hence, to give robust security for mobile operating systems the hybrid access policies can be considered. Applications: This hybrid approach might provide a good Android security framework with acceptable performance.
Effects of Environmental Temperature Change on Mercury Absorption in Aquatic Organisms with Respect to Climate Warming

Because of global warming, the quantity of naturally generated mercury (Hg) will increase, subsequently methylation of Hg existing in seawater may be enhanced, and the content of metal in marine products rise which consequently results in harm to human health. Studies of the effects of temperatures on Hg absorption have not been adequate. In this study, in order to observe the effects of temperature changes on Hg absorption, inorganic Hg or methylmercury (MeHg) was added to water tanks containing loaches. Loach survival rates decreased with rising temperatures, duration, and exposure concentrations in individuals exposed to inorganic Hg and MeHg. The MeHg-treated group died sooner than the inorganic Hg-exposed group. The total Hg and MeHg content significantly increased with temperature and time in both metal-exposed groups. The MeHg-treated group had higher metal absorption rates than inorganic Hg-treated loaches. The correlation coefficients for temperature elevation and absorption were significant in both groups. The results of this study may be used as basic data for assessing in vivo hazards from environmental changes such as climate warming.
A Highly Integrated Independently Tunable Triple-Band Patch Antenna

A highly integrated tunable triple-band patch antenna is designed and fabricated. Two U-slots are cut in the same radiating patch to achieve triple-band performance. While the antenna miniaturization is obtained by loading one patch edge with metalized vias, theory of characteristic modes is adopted to explain the U-slots scaling. The antenna radiating patch size is only 0. 1λ0 × 0. 17λ0. The operating frequencies can be independently tuned after properly inserting three varactor diodes into the radiating structure. The radiation patterns have similar unidirectional shapes with high stability of the resonant frequencies during the entire tuning of each band. Good agreement between simulation and measurement results is obtained. The antenna covers the following bands: 2.07–2.6 GHz, 2.86–3.57 GHz, and 4.59–5.39 GHz. The measured peak gains and efficiencies are 2.72 dBi and 62.6%, 2.76 dBi and 63.3%, and 2.87 dBi and 66.8%, respectively. Size reduction, multiband function, and independent tuning of three operating bands using only one antenna layer and one RF feedline are combined together to realize a compact and practical antenna.
Ketone Bodies, Potential Therapeutic Uses

Ketosis, meaning elevation of D‐ β‐hydroxybutyrate ( R ‐3‐hydroxybutyrate) and acetoacetate, has been central to starving man's survival by providing nonglucose substrate to his evolutionarily hypertrophied brain, sparing muscle from destruction for glucose synthesis. Surprisingly, D‐ β‐hydroxybutyrate (abbreviated “βOHB”) may also provide a more efficient source of energy for brain per unit oxygen, supported by the same phenomenon noted in the isolated working perfused rat heart and in sperm. It has also been shown to decrease cell death in two human neuronal cultures, one a model of Alzheimer's and the other of Parkinson's disease. These observations raise the possibility that a number of neurologic disorders, genetic and acquired, might benefit by ketosis. Other beneficial effects from βOHB include an increased energy of ATP hydrolysis ( ΔG') and its linked ionic gradients. This may be significant in drug‐resistant epilepsy and in injury and anoxic states. The ability of βOHB to oxidize co‐enzyme Q and reduce NADP + may also be important in decreasing free radical damage. Clinical maneuvers for increasing blood levels of βOHB to 2‐5 mmol may require synthetic esters or polymers of βOHB taken orally, probably 100 to 150 g or more daily. This necessitates advances in food‐science technology to provide at least enough orally acceptable synthetic material for animal and possibly subsequent clinical testing. The other major need is to bring the technology for the analysis of multiple metabolic “phenotypes” up to the level of sophistication of the instrumentation used, for example, in gene science or in structural biology. This technical strategy will be critical to the characterization of polygenic disorders by enhancing the knowledge gained from gene analysis and from the subsequent steps and modifications of the protein products themselves.
Citizens' Voice and Adoption of Pakistani E-Government Services

Even though there is emerging literature on e-government, research focused on potential problems related to citizens’ adoption of e-government services in developing countries is still limited. As a developing country, e-government services in Pakistan have witnessed prolific advancements over the years. Since 2002, Pakistan has strategically adopted e-government as a part of its policy. In this chapter, the factors influencing citizens’ e-government service adoption in Pakistan are examined using the unified theory of acceptance and use of technology model. The findings indicate that, in addition to the lack of awareness and data privacy, all of the factors specified by the model have an effect on the adoption of these services in Pakistan. The empirical results highlight the voice of citizens concerning the usage of the services. This information can be used by the policy and decision makers to promote services that correspond better to the needs of the citizens.
Fourier transform infrared difference spectroscopy shows no evidence for an enolization of chlorophyll a upon cation formation either in vitro or during P700 photooxidation.

Molecular changes associated with the photooxidation of the primary electron donor P700 in photosystem I from cyanobacteria have been investigated with Fourier transform infrared (FTIR) difference spectroscopy. Highly resolved signals are observed in the carbonyl stretching frequency region of the light-induced FTIR spectra. In order to assign and to interpret these signals, the FTIR spectra of isolated chlorophyll a and pyrochlorophyll a (lacking the 10a-ester carbonyl) in both their neutral and cation states were investigated. Comparison of the redox-induced FTIR difference spectra of these two model compounds demonstrates that upon chlorophyll a cation formation in tetrahydrofuran the 7c-ester carbonyl is essentially unperturbed while the 10a-ester carbonyl is upshifted from 1738 to 1751 cm-1. For the 9-keto group, the shift is from 1693 to 1718 cm-1 in chlorophyll a and from 1686 to 1712 cm-1 in pyrochlorophyll a. The 1718-cm-1 band in the difference spectrum of chlorophyll a is thus unambiguously assigned to the 9-keto carbonyl of the cation. Comparison of the light-induced FTIR difference spectrum associated with the photooxidation of P700 in vivo with the difference FTIR spectrum of chlorophyll a cation formation leads to the assignment of the frequencies of the 9-keto carbonyl group(s) at 1700 cm-1 in P700 and at 1717 cm-1 in P700+.
