Reversible Fragile Database Watermarking Technology using Difference Expansion Based on SVR Prediction

In this paper, the proposed scheme detects database tampering by embedding the important characteristics of the original database. The association rule of frequent pattern tree (FP-tree) data mining is utilized to determine the relationship existing among the protected attributes and others in the database. Meanwhile, support vector regression (SVR) is applied to predict each protected attribute value. By applying difference expansion (DE) and the differences between the original and predicted values, the owner can embed the digital watermark in the protected database. If the protected database is distorted, the SVR function can still predict the protected values. Then, an examination of the difference between original protected and predicted values allows for the extraction of the watermark. Data which has been tampered with can be found by comparing the original watermark with the extracted one. In this paper, FP-tree mining method is used to reduce SVR training time. Moreover, if the database has not been attacked then the proposed method can recover the original attribute values. When we extract watermark from the protected database and if this database has been tampered with, the proposed method can use the extracted watermark to authenticate and locate the tampered tuples. Therefore, the proposed database watermarking method can effectively authenticate the database integrity and protect the database.
Applying marketing mix constructs in higher education: the case of an MBA program in the UAE

This exploratory study identifies significant choice factors for prospective students when selecting a Master of Business Administration (MBA) program in the increasingly competitive higher education sector in the United Arab Emirates (UAE). Implications for Higher Education Institutions (HEIs) when they develop marketing communication strategies are addressed. Study participants included current MBA students, MBA graduates who have completed their degree at a British University's campus in the UAE and prospective students who chose not to enrol on that MBA program. Constructs were tested for reliability using the Cronbach alpha test. The relative importance of specific choice factors were assessed via analysis of the means of the constructs. The difference between the most important (People) and least important (Promotion) factors were as much as 34%. Differences between three groups of study participants were analysed based on the results of Scheffe's post-hoc test. Marketing implications for HEIs include: improving the quality of the factors identified and communicating the quality of these factors; especially intangible ones, to potential MBA candidates more effectively.
ERp44, a novel endoplasmic reticulum folding assistant of the thioredoxin family

In human cells, Ero1‐Lα and ‐Lβ (hEROs) regulate oxidative protein folding by selectively oxidizing protein disulfide isomerase. Specific protein–protein interactions are probably crucial for regulating the formation, isomerization and reduction of disulfide bonds in the endoplasmic reticulum (ER). To identify molecules involved in ER redox control, we searched for proteins interacting with Ero1‐Lα. Here, we characterize a novel ER resident protein (ERp44), which contains a thioredoxin domain with a CRFS motif and is induced during ER stress. ERp44 forms mixed disulfides with both hEROs and cargo folding intermediates. Whilst the interaction with transport‐competent Ig‐K chains is transient, ERp44 binds more stably with J chains, which are retained in the ER and eventually degraded by proteasomes. ERp44 does not bind a short‐lived ribophorin mutant lacking cysteines. Its overexpression alters the equilibrium of the different Ero1‐Lα redox isoforms, suggesting that ERp44 may be involved in the control of oxidative protein folding.

Toward Communication Strategies for Platooning: Simulative and Experimental Evaluation

Platooning, which is the idea of cars autonomously following their leaders to form a road train, has huge potential to improve traffic flow efficiency and, most importantly, road traffic safety. Wireless communication is a fundamental building block: It is needed to manage and maintain the platoons. To keep the system stable, strict constraints in terms of update frequency and communication reliability must be met. We investigate different communication strategies by explicitly taking into account the requirements of the controller, exploiting synchronized communication slots, and transmit power adaptation. As a baseline, we compared the proposed approaches to two state-of-the-art adaptive beaconing protocols that have been designed for cooperative awareness applications, namely, the European Telecommunications Standards Institute (ETSI) Decentralized Congestion Control (DCC) and Dynamic Beaconing (DynB). Our simulation models have been parameterized and validated by means of real-world experiments. Our results demonstrate that the combination of synchronized communication slots with transmit power adaptation is perfectly suited for cooperative driving applications, even on very crowded freeway scenarios.
America's Neglected Veterans: 1.7 Million Who Served Have No Health Coverage

Many U.S. military veterans lack health insurance and are ineligible for care in Veterans Administration health care facilities. Using two recently released national government surveys—the 2004 Current Population Survey and the 2002 National Health Interview Survey—the authors examined how many veterans are uninsured (lacking health insurance coverage and not receiving care from the VA) and whether uninsured veterans have problems in access to care. In 2003, 1.69 million military veterans neither had health insurance nor received ongoing care at Veterans Health Administration (VHA) hospitals or clinics; the number of uninsured veterans increased by 235,159 since 2000. The proportion of nonelderly veterans who were uninsured rose from 9.9 percent in 2000 to 11.9 percent in 2003. An additional 3.90 million members of veterans' households were also uninsured and ineligible for VHA care. Medicare covered virtually all Korean War and World War II veterans, but 681,808 Vietnam-era veterans were uninsured (8.7 percent of the 7.85 million Vietnam-era vets). Among the 8.27 million veterans who served during “other eras” (including the Persian Gulf War), 12.1 percent (999,548) lacked health coverage. A disturbingly high number of veterans reported problems in obtaining needed medical care. By almost any measure, uninsured veterans had as much trouble getting medical care as other uninsured persons. Thus millions of U.S. veterans and their family members are uninsured and face grave difficulties in gaining access to even the most basic medical care.
From liberal to conservative: shifting cultural policy regimes in post-Soviet Russia

In this paper, we analyze the evolution of Russian cultural policy from the end of the Soviet era through the current against the framework of welfare state regimes. The end of the Soviet Union 25 years ago ushered in a decade of liberalization marked by a withdrawal of the state from cultural responsibility and hopes that market demand and private support would emerge to fill in the void. With the latter hampered by the economic hardships of the transition and the loss of philanthropic traditions after more than 70 years of communism, a liberal policy regime did not take firmly hold and has gradually been replaced by a new cultural policy consensus more akin to a conservative welfare regime, marked by a return of the state to a more dominant role with the support of core cultural policy constituencies.
Temporal Decay in Timber Species Composition and Value in Amazonian Logging Concessions

Throughout human history, slow-renewal biological resource populations have been predictably overexploited, often to the point of economic extinction. We assess whether and how this has occurred with timber resources in the Brazilian Amazon. The asynchronous advance of industrial-scale logging frontiers has left regional-scale forest landscapes with varying histories of logging. Initial harvests in unlogged forests can be highly selective, targeting slow-growing, high-grade, shade-tolerant hardwood species, while later harvests tend to focus on fast-growing, light-wooded, long-lived pioneer trees. Brazil accounts for 85% of all native neotropical forest roundlog production, and the State of Pará for almost half of all timber production in Brazilian Amazonia, the largest old-growth tropical timber reserve controlled by any country. Yet the degree to which timber harvests beyond the first-cut can be financially profitable or demographically sustainable remains poorly understood. Here, we use data on legally planned logging of ~17.3 million cubic meters of timber across 314 species extracted from 824 authorized harvest areas in private and community-owned forests, 446 of which reported volumetric composition data by timber species. We document patterns of timber extraction by volume, species composition, and monetary value along aging eastern Amazonian logging frontiers, which are then explained on the basis of historical and environmental variables. Generalized linear models indicate that relatively recent logging operations farthest from heavy-traffic roads are the most selective, concentrating gross revenues on few high-value species. We find no evidence that the post-logging timber species composition and total value of forest stands recovers beyond the first-cut, suggesting that the commercially most valuable timber species become predictably rare or economically extinct in old logging frontiers. In avoiding even more destructive land-use patterns, managing yields of selectively-logged forests is crucial for the long-term integrity of forest biodiversity and financial viability of local industries. The logging history of eastern Amazonian old-growth forests likely mirrors unsustainable patterns of timber depletion over time in Brazil and other tropical countries.

The ontogenetic scaling of bite force and head size in loggerhead sea turtles (Caretta caretta): implications for durophagy in neritic, benthic habitats

SUMMARY Ontogenetic studies of vertebrate feeding performance can help address questions relevant to foraging ecology. Feeding morphology and performance can either limit access to food resources or open up new trophic niches in both aquatic and terrestrial systems. Loggerhead sea turtles are long-lived vertebrates with complex life histories that are marked by an ontogenetic shift from an oceanic habitat to a coastal neritic habitat, and a transition from soft oceanic prey to hard, benthic prey. Although considered durophagous and strong biters, bite performance has not been measured in loggerheads, nor has the ontogeny of bite performance been characterized. In the present study, we collected measurements of bite force in loggerhead turtles from hatchlings to adults. When subadults reach the body size at which the ontogenetic shift occurs, their crushing capability is great enough for them to consume numerous species of hard benthic prey of small sizes. As loggerheads mature and bite performance increases, larger and harder benthic prey become accessible. Loggerhead bite performance eventually surpasses the crushing capability of other durophagous carnivores, thereby potentially reducing competition for hard benthic prey. The increasing bite performance and accompanying changes in morphology of the head and jaws are likely an effective mechanism for resource partitioning and decreasing trophic competition. Simultaneous measurements of body and head size and the use of non-linear reduced major axis regression show that bite force increases with significant positive allometry relative to body size (straight carapace length, straight carapace width and mass) and head size (head width, height and length). Simple correlation showed that all recorded morphometrics were good predictors of measured bite performance, but an AICc-based weighted regression showed that body size (straight carapace width followed by straight carapace length and mass, respectively) were more likely predictors of bite force than head size morphometrics (head width and head length).
Jasmonic acid promotes degreening via MYC2/3/4- and ANAC019/055/072-mediated regulation of major chlorophyll catabolic genes.

Degreening caused by rapid chlorophyll (Chl) degradation is a characteristic event during green organ senescence or maturation. Pheophorbide a oxygenase gene (PAO) encodes a key enzyme of Chl degradation, yet its transcriptional regulation remains largely unknown. Using yeast one-hybrid screening, coupled with in vitro and in vivo assays, we revealed that Arabidopsis MYC2/3/4 basic helix-loop-helix proteins directly bind to PAO promoter. Overexpression of the MYCs significantly enhanced the transcriptional activity of PAO promoter in Arabidopsis protoplasts, and methyl jasmonate (MeJA) treatment greatly induced PAO expression in wild-type Arabidopsis plants, but the induction was abolished in myc2 myc3 myc4. In addition, MYC2/3/4 proteins could promote the expression of another Chl catabolic enzyme gene, NYC1, as well as a key regulatory gene of Chl degradation, NYE1/SGR1, by directly binding to their promoters. More importantly, the myc2 myc3 myc4 triple mutant showed a severe stay-green phenotype, whereas the lines overexpressing the MYCs showed accelerated leaf yellowing upon MeJA treatment. These results suggest that MYC2/3/4 proteins may mediate jasmonic acid (JA)-induced Chl degradation by directly activating these Chl catabolic genes (CCGs). Three NAC family proteins, ANAC019/055/072, downstream from MYC2/3/4 proteins, could also directly promote the expression of a similar set of CCGs (NYE1/SGR1, NYE2/SGR2 and NYC1) during Chl degradation. In particular, anac019 anac055 anac072 triple mutant displayed a severe stay-green phenotype after MeJA treatment. Finally, we revealed that MYC2 and ANAC019 may interact with each other and synergistically enhance NYE1 expression. Together, our study reveals a hierarchical and coordinated regulatory network of JA-induced Chl degradation.
A kinetic analysis of the endplate ion channel blocking action of disopyramide and its optical isomers

1 The effects of the antiarrhythmic agent disopyramide was studied on responses from voltage‐clamped endplates at the neuromuscular junction of the garter snake. 2 Disopyramide reduced endplate current amplitude and decay time constant in a concentration‐and voltage‐dependent manner. Endplate current decays remained monophasic in the presence of the drug. These results were interpreted in terms of the drug blocking the open form of the acetylcholine receptor‐ion channel complex. 3 Disopyramide produced a greater reduction of the amplitude of endplate currents than of miniature endplate currents. The reduction in miniature endplate current amplitude was not voltage‐dependent. Analysis of endplate current driving functions showed that this was due to the rapid occurrence of channel block during the rising phase of the endplate current. The residual reduction, apart from that produced by channel block, is most probably due to receptor block. 4 Disopyramide had a voltage‐dependent blocking rate constant of about 107 m−1 s−1 at −90 mV. The unblocking rate constant was estimated from the results of experiments using paired ionophoretically applied pulses of acetylcholine. This value was again voltage‐dependent and approximately 1 s−1. 5 The actions of the (+)‐and (‐)‐stereoisomers of disopyramide on endplate current decay were identical, indicating that the channel binding site at the neuromuscular junction is not stereoselective.
Pulsed dye laser treatment of genital warts

Genital warts represent benign epithelial proliferations induced by human papillomavirus. The goal of treatment is the clearance of visible warts. Different regimens are available. Flashlamp‐pumped pulsed dye laser (FPDL) represents one of many treatment options for the management of viral warts (verrucae vulgares), its effectiveness being comparable with that of conventional therapies. We evaluated the effectivity of FPDL light for the treatment of genital warts.
Treatment Patterns in Alpha-Blocker Therapy for Benign Prostatic Hyperplasia

This study examined treatment patterns and patient characteristics of men initiating alpha adrenergic blocker therapy (alpha-blocker) for benign prostatic hyperplasia (BPH). The 2009 Thomson Reuters MarketScan® Database was used to identify the newly initiated alpha-blocker: men ≥40 years old with continuous medical and pharmacy coverage for 12 months before and after alpha-blocker initiation, with no alpha-blocker or 5-alpha-reductase inhibitors in the previous year, and with ≥1 BPH diagnosis within 1 month before and 6 months after alpha-blocker initiation. This study analyzed patient demographics, clinical characteristics, adherence (percentage of men achieving medication possession ratio [MPR] ≥ 0.8), restarting the same alpha-blocker after discontinuation, switching to another BPH medication, and type of alpha-blocker (alpha 1 type selective or alpha 1 subtype selective agents). T tests and chi-square tests compared differences at the . 05 significance level. A total of 13,474 men met the study criteria (mean age of 63.1 years). Two thirds of the men discontinued alpha-blocker in the 12-month period, among which restarts or switches were statistically different (p = .036) but numerically similar across cohorts. Adherence for alpha 1 type selective agents versus alpha 1 subtype selective agents at 6 months was 43.3% versus 38.1% (p < .01); at 12 months, 34.4% versus 30.5% (p < .01). Alpha-blocker discontinuation rates were high, which confirms low medication adherence reported among medications for several other chronic conditions; therefore, it is necessary to understand the reasons for alpha-blocker discontinuation.
Characterization of nuclear microsatellite markers for Rumex bucephalophorus (Polygonaceae) using 454 sequencing

Premise of the study: Nuclear microsatellite markers were developed in Rumex bucephalophorus subsp. canariensis (Polygonaceae) to investigate its genetic diversity and structure. Methods and Results: Sixteen polymorphic microsatellite markers were obtained using 454 next-generation sequencing with di-, tri-, and tetranucleotide repeats. The average number of alleles was 5.688 and 3.813 for R. bucephalophorus subsp. canariensis var. canariensis and var. fruticescens, respectively. Slightly higher levels of mean genetic diversity were found in var. canariensis (expected heterozygosity = 0.600) than in var. fruticescens (expected heterozygosity = 0.514). Cross-amplifications in related taxa within R. bucephalophorus showed good amplification and polymorphic patterns. Conclusions: These 16 novel nuclear microsatellite markers are the first in the genus Rumex and may serve as valuable tools to carry out studies on genetic diversity and structure as well as progeny studies.
Women and substance use: a qualitative study on sexual and reproductive health of women who use drugs in Delhi, India

Objectives To explore contextual factors that increase vulnerabilities to negative sexual and reproductive health (SRH) outcomes and possible differences in SRH-related behaviours and the needs of women who use drugs (WUD) through non-injecting and injecting routes. Design Qualitative study design using semi-structured in-depth interviews. Participants Twenty women who injected drugs in the past 3 months and 28 women who reported using drugs through non-injecting routes in the past 1 month. Setting Interviews were conducted at community-based, drop-in centres in Delhi, India. Results Study findings illustrate that WUD were sexually active and had multiple sex partners including clients of sex work. Transient relationships were reported and many participants engaged in unsafe sex. Factors which affected safe sex behaviours included: gender power imbalance, limited agency for decision-making, lack of accurate information for correct self-risk assessment, and being under the influence of drugs. Despite high awareness, low and inconsistent contraceptive use was reported. Some participants were coerced to conceive while a few others reported their inability to conceive. Violence was a key determinant for SRH outcomes. Perception of certain adverse health outcomes (such as infertility) to be ‘common and expected among WUD’ influenced access to healthcare. Further, healthcare providers’ stigmatising attitudes and lack of women-centric services deterred women from uptake of healthcare services. Conclusion Findings highlight that SRH-related behaviours and needs of this group are a complex interplay of multiple determinants which need to be addressed at all levels: individual, family, community and institutional. It is imperative to roll out a ‘one-stop-shop’ for a comprehensive package of health services. Expansion of existing drop-in-centres could be considered for setting-up community-based women-centric services with appropriate linkage to drug dependence treatment and reproductive health services.
The Possible Roles of Ethanol in the Relationship Between Plants and Frugivores: First Experiments with Egyptian Fruit Bats1

Abstract In this paper we discuss how yeast, fungi ubiquitously present in sugar-rich fruit, can influence the interaction between frugivores and fleshy-fruited plants via ethanol. We suggest that plants, the seeds of which are mostly dispersed by vertebrates, exploit the ethanol from alcoholic fermentation by yeast in their seed dispersal strategy. Moderate consumption of ethanol, i.e., at concentrations close to those in naturally ripening fruit, by frugivores may have beneficial short- and long-term effects for these potential dispersers, whereas consumption of larger quantities may have negative short- and long-term effects. Ethanol vapor emanating from palatable fruit may act as an odor cue, guiding bats and other frugivores to the fruit, and aiding them to assess its quality. In addition, we suggest that ingested ethanol may be an appetitive stimulant. We also evaluate the possibility that ethanol within fruit may be used as a source of energy by frugivorous vertebrates. Our preliminary data indicate that Egyptian fruit bats (Rousettus aegyptiacus) can use the odor of ethanol to assess food suitability, but also that it may not serve as an attractant over short distances (i.e., <1 m). Instead, ethanol is avoided at concentrations greater than 1%, a value which might typically characterize overripe and otherwise unpalatable fruit. Our initial results further indicate that Egyptian fruit bats significantly decrease their food consumption if it contains 1 or 2% ethanol. Overall, ethanol may play diverse roles in the nutritional ecology and behavior of fruit-eating bats, and in the interaction between frugivores and plants, in general.
