Modeling the Cost Reduction of Master Data Management

Much research has been done on the advantages of Master Data Management (MDM) and the problems that poor MDM may cause. Much is also known about the importance of data quality. However little is known about quantifying and structuring the costs related to MDM. In this thesis the question ”How can the possible reduction of costs for organizations which may result from implementing Master Data Management be modeled? ” is investigated. This research presents an extensible meta-model for the costs related to MDM, which provides a method to structure these costs and compare them in different situations (e.g. before and after an MDM project) to calculate the possible cost reduction. In addition to the meta-model, a support tool has been developed, which acts as an operationalization of the meta-model and helps to model, visualize and compare these costs. Together, these provide a powerful set of tools to model the costs related to MDM, visualize the risks of poor MDM and show the importance of proper MDM. The advantage of our research is that the meta-model provides a fixed hierarchy, but gives the user enough modeling freedom to model their specific situations. Furthermore, the support tool provides an easy to use user interface to model and compare the costs and visualize the risks of poor MDM to an organization, which might convince them to start an MDM project to improve their master data quality (MDQ). Additionally, the support tool uses the extensible meta-model and is therefore powerful enough to model processes in detail as well. This means that the tool could not only be used to quickly show the costs and risks of poor MDM, but could also be used to thoroughly analyze the MDM situation within an organization.
A report on antimutagenic and antioxidant activities of Gallic Acid

Gallic acid (3,4,5-trihydroxybenzoic acid) is an organic acid and naturally occurring polyhydroxyphenolic compound abundantly found in various fruits and vegetables. This compound is widely used to cure various disorders and has anti-inflammatory, antibacterial, antifungal, antiviral, antidiabetic, antimalarial and antiallergic activities. Therefore, this study was planned to investigate its other medicinal values such as antimutagenic and antioxidant activities. The antimutagenic activity of gallic acid was checked by using Ames assay. Antioxidant activities was determined through various in vitro assays like DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging assay, lipid peroxidation, deoxyribose degradation (site-specific and non-site specific modes), and reducing power assay. In the present study, gallic acid showed strong free radical scavenging and antimutagenic effects in both in vitro antioxidant and antimutagenic assays.
Flying in Cyberspace: Policing Global Travel Fraud

Airline tickets that have been obtained illicitly represent a truly global crime. The travel industry and law enforcement have been attempting to address travel fraud for some time. Airline tickets can be obtained using various cybercrime methods. They are traded and advertised on online blackmarkets and through fraudulent travel agencies. This research is qualitative in nature, informed by interviews with law enforcement and industry stakeholders, as well as the analysis of a marketplace where fraudulently obtained tickets are traded. This research considers: the nature of the criminal market for fraudulently obtained tickets, the involvement of co-offending and organized crime, the geographic nature of travel fraud, and the ways in which those supplying fraudulently obtained tickets try to avoid detection. Also considered is how the nature of travel fraud has changed over time, ways in which it may continue to change, and the challenges faced by law enforcement.
The Visualization of Flame Temperature from Combustion of Hydrous Ethanol under CI Engine Condition

This paper investigates the flame temperature of hydrous ethanol under CI engine condition via the two-color method. Tests have been performed in the rapid compression and expansion machine (RCEM) equipped with a high-pressure fuel injection system. Tested fuels are hydrous ethanol with 5% by weight water and 1% by weight Lauric acid (Eh95) and hydrous ethanol blended with commercial additive (ED95). The results revealed that hydrous ethanol with commercial additive (ED95) showed differences, not only in flame temperature, but also KL factor (i.e. soot concentration) from hydrous ethanol with 5% water by weight and 1% Lauric acid by weight (Eh95). Both tested fuels have two peaks in flame temperature history. The first peak is the effect of the intensity of premixed combustion. The second peak is the effect of increasing of combustion rate due to increased entrained air into spray. KL factor is over combustion periods, but higher generation rate of KL factor occurred at the end of combustion.
CONFLICT INITIATION, RESOLUTION, AND OUTCOMES IN FRANCHISE CHANNEL RELATIONSHIPS: THE ROLE OF REGULATION

Franchise relationships are prone to conflict. So as to safeguard the rights of individual franchisees, several states have legislated greater franchisor disclosure (registration law) and/or franchisor “termination for good cause” (relationship law). The impact of regulatory oversight on franchisor-franchisee conflict, however, remains unclear. Relying on agency theory arguments, we first assess the impact of the regulatory context by itself and in combination with franchisors’ dual distribution structure on the incidence of litigated conflict. Conditional on litigation, we also predict the impact of franchise regulation on the incidence, nature, and outcomes of franchisorfranchisee conflict. We test our hypotheses using a unique multi-source, archival database of 411 instances of litigation for 75 franchise systems observed over 17 years. Parties’ litigation initiation and resolution choices are seen to be driven by regulatory constraints and their interaction with the dual distribution structure of the franchise system, and to result in a trade-off between prevailing in the particular conflict and achieving franchise system growth objectives.
Overreaction and Multiple Tail Dependence at the High-frequency Level — The Copula Rose

This paper applies a non- and a semiparametric copula-based approach to analyze the first-order autocorrelation of returns in high frequency financial time series. Using the EUREX D3047 tick data from the German stock index, it can be shown that the temporal dependence structure of price movements is not always negatively correlated as assumed in the stylized facts in the finance literature. Depending on the sampling frequency, the estimated copulas exhibit some kind of overreaction phenomena and multiple tail dependence, revealing patterns similar to the compass rose.

The velocity planning of cloth frame and the spindle speed arithmetic are researched. Then the time-optimal control principle is proposed to scheme the frame velocity curve and the minimum movement time. Test Results show that it can reach 2800 stitches per minute, which is the international level.
Redefining Political Terrorism: Nigerian Media and the Crisis of Democratization

In Nigeria, there is little dispute about the power and role of the media as agenda-setting agency. What is subject of disput is whose interest the agenda ultimately serves - the elite or the masses? Despite the avalanche of evidence that Nigeria’s electoral processes had not met the least benchmark of credibility since the country returned to civil rule in 1999, political analyses and advertising in the media tended to gloss over previous electoral flaws in their quest to ascribe invincibility to political elites. The effect of this is that the political elite are emboldened in their brazen manipulation of the electoral processes, which is a terrorism of sorts. While there is claim of balance between the media’s commercialistic interests and public good, evidence suggests that Nigeria’s political elite have used the instrumentality of the media to rewrite and embellish their political fortunes. This paper examines the mechanisms of political terrorism within the context of elite-media convergence and argues that the consolidation of democratic governance in Nigeria entails the dismantling of all the operational pitfalls that fuel and sustain political terrorism in all its ramifications.

The mediating role of trust in the relationship between e-retailer quality and customer intention of online shopping

This study aims to explore the role of trust in the relationship between e-retailer quality and customer’s intention to shop online. System quality, information quality, and service quality were applied as e-retailer quality and antecedents to affect customer trust in e-retailer, and hence, intention to shop online was motivated. Data were gathered from a sample of 325 members of e-bookstore in Taiwan and was tested using the structural equation model. Results showed that trust played a critical mediating role between e-retailer quality and customer intention to shop online. Both system quality and service quality positively affected trust of e-retailer directly, and indirectly affected customer intention of online shopping. However, information quality revealed non-significant impact neither on trust perception of participants nor on their intention to shop online. The implications of these findings for both researchers and practitioners were discussed. Key words: System quality, information quality, service quality, trust, e-retailer.
RAPD ANALYSIS OF GENETIC VARIATION IN NATURAL POPULATIONS OF AEGILOPS SP. FROM SOUTH ADRIATIC

New challenges that food production is facing, requires novel approach in agricultural strategy. The scissors of growing demand for food and the limits of the Earth's resources are forcing plant breeders to run for the new borders, utilizing all the available genetic variation in order to create fruitful and economically sound cultivars. Aegilops sp. (Poaceae) is a potential source of genetic variation for wheat improvement. RAPD marker analysis was used in order to distinguish and evaluate different genotypes of Aegilops sp. population samples from the collection gathered during few years’ expeditions in South Adriatic, along the coastal, littoral and the inland parts of Montenegro. Ten randomly amplified polymorphic DNA markers (RAPDs) were tested: OPA-05, OPA-08, OPB-06, OPA-02, OPA-07, OPA-25, OPB-07, OPB-18, OPC-06, OPC-10 to examine genetic structuring on 18 samples of 6 populations of different Aegilops sp. According to global AMOVA, 75% of total gene diversity was attributable mostly to diversity within population (ΦPT =0.205 p=0.001), indicating that the groups of studied goat grass populations were seemingly to differing genetically. In contrast, 25% of the variation came from variation among populations. According to PCoA, the distribution of 18 goat grass accessions by Principal Coordinate Analysis shows 3 distinct groups. PCo axis 1, PCo axis 2, and PCo axis 3 account for 20.8%, 18.2% and 14.1% of the variation, respectively. The results showed that RAPD markers could be a convenient tool for investigating genetic variation and for detecting genetic structuring of populations. Genetic variability formed under natural selection was entrenched.
Massive mortality associated with Streptococcus iniae infection in cage-cultured red drum (Sciaenops ocellatus) in Eastern China

In August, 2011, an enzootic disease characterized by hemorrhage throughout body surface, enlarged spleen and kidney occurred in cage farmed red drum fish, in Dongtou, Zhejiang of China. The diseased fish weighed between 100 to 200 g, and the cumulative mortality within 60 days was higher than 70%. Several bacterial isolates that exhibited the same phenotypic traits and biochemical characteristics were isolated from the lesions of diseased fish. According to the results obtained from biochemical tests and sequence analysis of the 16S rDNA, the disease’s pathogen (strain WZMH110819) was identified as Streptococcus iniae. In the challenge trials, the LD50 value of the clinical bacterial isolate WZMH110819 was 9.65×106 CFU per fish. Moreover, bath exposure or oral administration by Streptococcus iniae also caused a considerable number of deaths in fish. Antibiotic susceptibility tests showed that strain WZMH110819 was sensitive to most of the antibiotics including ampicillin, erythromycin and gentamicin in vitro. This finding has provided a basis for the control and prevention of further outbreaks of this enzootic disease in red drum farms. Key words: Streptococcus iniae, Sciaenops ocellatus, biochemical characterization, 16S rDNA analysis.
A Survey of Trust and Risk Metrics for a BYOD Mobile Worker World : Third International Conference on Social Eco-Informatics

Users increasingly access corporate data from their own devices and public wireless networks such airports Wi-Fi or coworking offices. On one hand, more work is possible, but on the other hand, it is riskier because the devices and locations may be untrustworthy. However, the Bring-Your-Own-Device trend is a fact and it is the reason we survey in this paper how computational trust and risk metrics may help mitigating those new risks in a more dynamic way than in the past. An online survey that we have carried out confirms that users do not take care of security risks as they are communicated today and that new Human Computer Interfaces combined with opportunity-enabled risk management are needed to improve the situation.
Experimental model for safe in vitro- and in vivo- influence of internal and external factors of cell differentiation

Gene transfer in laboratory-cultivated mouse embryonic stem cells (mESCs) was made by appropriate recombinant DNA-constructs. Electrophoretic profiles of genetic material from wild type on oncogene Dcn1 and “knock-down” on it inbred experimental mice differed not only in it, but also in tumorsuppressor gene HACE1 between both categories of laboratory rodents. The results obtained were compared with previous data, received from malignant rat insulinoma RIN-5F cells, transfected by recombinant gene constructs with inserted copy of “secretagogin” gene, by their in vitro-co-cultivation with malignant cell precursors, derived from populations of non-transfected laboratory-cultivated mESCs in the presence of Doxyciclin, probably by activation of tumor-suppressor genes of STATfamily. Furthermore, the so induced “secretagogin” over-expression could exert protective function on the transfected Rin-5F cells, which was confirmed by noticed differences in the degree of myeloid differentiation of derived precursor cells in their in vitro-co-cultivation with containing additional copy of “secretagogin” gene Rin-5F malignant rat insulinoma cells, in comparison with the results, obtained in their co-cultivation with human cervical carcinoma Hela cells in our laboratory. On the other hand, the derived normal cells with inserted additional copy of oncogene indicated good safety and immunogenity.
Hydrogel-based reinforcement of 3 D bioprinted constructs 2 1

Progress within the field of biofabrication is hindered by a lack of 13 suitable hydrogel formulations. Here, we present a novel approach based on a 14 hybrid printing technique to create cellularized 3D printed constructs. The hybrid 15 bioprinting strategy combines a reinforcing gel for mechanical support with a bioink 16 to provide a cytocompatible environment. In comparison with thermoplastics such as 17 ε-polycaprolactone, the hydrogel-based reinforcing gel platform enables printing at cell18 friendly temperatures, targets the bioprinting of softer tissues and allows for improved 19 control over degradation kinetics. We prepared amphiphilic macromonomers based on 20 poloxamer that form hydrolysable, covalently cross-linked polymer networks. Dissolved 21 at a concentration of 28.6%w/w in water, it functions as reinforcing gel, while a 5%w/w 22 gelatin-methacryloyl based gel is utilized as bioink. This strategy allows for the creation 23 of complex structures, where the bioink provides a cytocompatible environment for 24 encapsulated cells. Cell viability of equine chondrocytes encapsulated within printed 25 constructs remained largely unaffected by the printing process. The versatility of the 26 system is further demonstrated by the ability to tune the stiffness of printed constructs 27 between 138 and 263 kPa, as well as to tailor the degradation kinetics of the reinforcing 28 gel from several weeks up to more than a year. 29

Oil Price Shocks and Monetary Policy in an Asymmetric Monetary Union

This paper analyzes the dynamic effects of anticipated and unanticipated oil price increases in a small two-country monetary union, which is simultaneously characterized by asymmetric wage adjustments and asymmetric interest rate sensitivities of private absorption. It is shown that both types of oil price disturbances lead to temporary divergences in output developments across the monetary union. In the case of anticipated oil price increases the relative cyclical position of output effects is reversed in the course of the adjustment process. With anticipated oil price increases complete stabilization of the output variables throughout the overall adjustment process requires restrictive monetary policy to be time-inconsistent from a quantitative but time-consistent from a qualitative point of view. That means that the central bank credibly announces a future reduction in the growth rate of nominal money stock but actually realizes a decrease in the monetary growth rate, which is less restrictive than the announcement.

On local non-zero constraints in PDE with analytic coefficients

We consider the Helmholtz equation with real analytic coefficients on a bounded domain $\Omega\subset\mathbb{R}^{d}$. We take $d+1$ prescribed boundary conditions $f^{i}$ and frequencies $\omega$ in a fixed interval $[a,b]$. We consider a constraint on the solutions $u_{\omega}^{i}$ of the form $\zeta(u_{\omega}^{1},\ldots,u_{\omega}^{d+1},\nabla u_{\omega}^{1},\ldots,\nabla u_{\omega}^{d+1})\neq0$, where $\zeta$ is analytic, which is satisfied in $\Omega$ when $\omega=0$. We show that for any $\Omega^{\prime}\Subset\Omega$ and almost any $d+1$ frequencies $\omega_{k}$ in $[a,b]$, there exist $d+1$ subdomains $\Omega_{k}$ such that $\Omega^{\prime}\subset\cup_{k}\Omega_{k}$ and $\zeta(u_{\omega_{k}}^{1},\ldots,u_{\omega_{k}}^{d+1},\nabla u_{\omega_{k}}^{1},\ldots,\nabla u_{\omega_{k}}^{d+1})\neq0$ in $\Omega_{k}$. This question comes from hybrid imaging inverse problems. The method used is not specific to the Helmholtz model and can be applied to other frequency dependent problems.
