Fraud Prevention and Internal Control in the Nigerian Banking System

This paper examines the issues of internal control viz., fraud prevention in the banking industry, adopting both primary and secondary data. Primary data was used to test internal control while secondary data were employed to test fraud prevention. The main primary variables were separation of duties, monitoring, and staff qualifications while the main secondary variables are bank profit, regulation, technology and M2. In both cases regression techniques were adopted. The results show that internal control on its own is effective against fraud, but not all staff are committed to it, while the secondary data is quite supportive of the primary data but more exemplifying in that M2, staff qualifications and technology were significant throughout the various dependent variables. It is also clear from the regressions that technological based fraud is significant. The paper recommends the continuation of the cashless policy of the Central Bank to reduce available cash and improvement in educated staff engagement to reduce fraud in the banking system.
A parameter tuning method to analyse the influence of algorithmic parameters in combination with instance characteristics on the quality of a Pareto front

In this paper, the eff? ect of the algorithmic parameters and instance characteristics on the quality of a Pareto front is analysed. The algorithm for which the parameters are evaluated is the variable neighborhood tabu search that is used to solve a multi-objective microzone-based vehicle routing problem. To evaluate the eff? ectiveness of the parameter sett? ings that are used to tune the aforementioned mentioned algorithm, diff? erent performance indices, which evaluate the quality of the Parote set, are used. The Promethee method is employed to select the combination of sett? ings that is deemed “the best” by the decision maker.
Prediction and Depiction of Potential RNA-Based Therapeutics for Oncogenic E6 and E7 Genes of Human Papilloma Virus Types 16 & 18: A New Class of Treatment for Lung Cancer

Unlike almost all the cervical, penile, vulvar, and anal cancers, where Human papilloma virus has long known to play a vital role, a causative link between carcinogenic Human papilloma virus and lung cancer have been found to be highly variable and contradictory. Data also shows geography and race-dependenty. Apart from etiological factors, viral carcinogen can manipulate the cell cycle, hamper cell apoptosis and also interrupt the cell division in host cell which lead to the lung cancer. Molecular studies of carcinogenic Human papilloma virus have found that E6/E7 acts as mitotic mutators which play an important role in pathogenicity and oncogenicity. Analysis of genome sequence of Human papilloma virus revealed that ORF having conserved in early region, E6 and E7 required for viral pathogenicity and oncogenicity can be the suitable target for RNAi technology. RNAi works by silencing or turning off gene expression to control pathogenicity and oncogenicity by blocking its replication processes. Therefore, the work is done on the basis of rational siRNA designing method by targeting viral oncogenic E6 and E7 genes of Human papilloma virus types16 & 18. Searching siRNA target sequences, multiple sequence alignment, forecasting secondary structure and RNA-RNA interaction prediction was done by various computational software tools for designing RNA-based therapeutics (siRNA). In this study, four effective siRNA were predicted rationally for oncogenic E6 and E7 genes of Human papilloma virus types 16 & 18 which might be used as a potential RNA based therapeutics to control the rate of carcinogenesis and degree of oncogenicity. The outcome of this study provides a basis of the researchers towards understating to development of RNA-based therapeutics (siRNA) at genomic level.
Multiple Facets of Self-Esteem and their Relations to Depressive Symptoms

The authors examined whether stability and level of self-esteem interact with daily hassles in predicting severity of depressive symptoms. As predicted, Time 2 depression scores (with Time 1 scores controlled) were highest among individuals with unstable self-esteem who reported considerable daily hassles. By contrast, self-esteem level did not interact with daily hassles to predict Time 2 depressive symptoms. These findings held even after negative self-concept items were eliminated from the depressive symptom inventories. Additional analyses revealed that self-esteem stability accounted for variance independent of the tendency to over generalize following failure or negative event attributional style. These findings support the contention that unstable self-esteem reflects fragile feelings of self-worth that exacerbate depressive symptoms under certain circumstances.
(2+1)-Dimensional mKdV Hierarchy and Chirp Effect of Rossby Solitary Waves

By constructing a kind of generalized Lie algebra, based on generalized Tu scheme, a new (2 + 1)-dimensional mKdV hierarchy is derived which popularizes the results of (1 + 1)-dimensional integrable system. Furthermore, the (2 + 1)-dimensional mKdV equation can be applied to describe the propagation of the Rossby solitary waves in the plane of ocean and atmosphere, which is different from the (1 + 1)-dimensional mKdV equation. By virtue of Riccati equation, some solutions of (2 + 1)-dimensional mKdV equation are obtained. With the help of solitary wave solutions, similar to the fiber soliton communication, the chirp effect of Rossby solitary waves is discussed and some conclusions are given.
Return of the Vision Video: Can Corporate Vision Videos Serve as Setting for Participation?

This paper examines the role of corporate vision videos as a possible setting for participation when exploring the future potentials (and pitfalls) of new technological concepts. We propose that through the recent decade’s rise web 2.0 platforms, and the viral effects of user sharing, the corporate vision video of today might take on a significantly different role than before, and act as a participatory design approach. This address the changing landscaping for participatory and user-involved design processes, in the wake of new digital forms of participation, communication and collaboration, which have radically changed the possible power dynamics of the production life cycle of new product developments. Through a case study, we pose the question of whether the online engagements around corporate vision videos can be viewed as a form of participation in a design process, and thus revitalize the relevance of vision videos as a design resource?
Cross-Cultural Collaboration in Design Engineering – Influence Factors and Their Impact on Work Performance

Design engineering has become a global business. Accordingly, design engineers are confronted with a need to collaborate with other design engineers, coming from different countries from all parts of the world. So engineers with entirely different cultural backgrounds have to successfully work together in design teams. Some of them succeed better in this task, some worse. An unsolved question is why there are these differences in performing cross-cultural collaboration. This paper presents an approach to determining factors in the backgrounds of design engineers, which influence their way of performing design tasks in cross-cultural collaboration. A qualitative study has been deployed therefore. Study design, conduction and results are presented in this paper.
Intelligent surveillance and pose-invariant 2D face classification

We describe recent advances in a project being undertaken to trial and develop advanced surveillance systems for public safety. One goal of the project is to trial commercial technologies in public spaces to evaluate their performance. Another is to develop and trial enhanced capabilities that will lead to more effective surveillance systems. A key technology being developed within the group is reliable face in the crowd identification from conventional CCTV cameras. While this is acknowledged to be a challenging problem, we have made considerable progress on several fundamental issues including recognition robust to large pose angles. We also describe a reconfigurable smart camera we are developing to handle the problem of obtaining high resolution face images while simultaneously surveilling large crowds in real-time.
Nonparametric methods for employment termination times with competing causes

A dataset of termination times of a company is analyzed by fitting a competing risk model, taking left truncation and right censoring into account. The analysis intends to provide evidence for a claim of age discrimination. The model imposes no functional form on the parameters of interest, namely the survivor, cause-specific hazard, and cumulative incidence functions. The empirical estimators are modified to account for delayed entry. Inference is primarily based on smoothed empirical hazard functions. The approach provides a frequentist alternative to the Bayesian analysis advocated by Kadane and Woodworth (2004) and is easy to implement using existing software.
Resolving the Confusion: Amietia vertebralis and A. umbraculata Tadpole Morphology

Morphological similarities between the tadpoles of Amietia umbraculata and A. vertebralis have led to confusion and incorrect descriptions and identifications in the literature. Based on 33 body measurements and ratios we revised the morphological descriptions of the tadpoles of the two species. Tadpole identification was verified through DNA sequencing using mitochondrial (16S) gene fragments. A combination of four morphological characters proved to be informative and consistent in distinguishing between tadpoles of the two species. Tadpoles of A. umbraculata are characterized by having four labial tooth rows in the lower jaw, extensive tail mottling, a dorsal fin that originates well behind the body, reaching a maximum depth at 50% of the tail length, and an average tail length of 1.9 times body length. Amietia vertebralis tadpoles on the other hand are characterized by having five or more labial tooth rows in the lower jaw, tail mottling that is confined to the upper half of the tail musculature, a dorsal fin that originates at the body-tail junction but retains a low profile, rising abruptly to reach a maximum depth at about 40% of the tail length, and an average tail length of 1.5 times body length. These four characters identify the two species without ambiguity.
Risk Sharing Partnerships With Suppliers: The Case of EMBRAER

Since the mid 1990s, the global aircraft industry has been creating new solutions for product development. Risksharing partnerships with suppliers began to be established in an attempt to reduce investments and, consequentially, the dependence on loans. The partners began not only to invest in tooling, engineering and infrastructure, but also to participate more directly in the projects, in the investments and design activities, acquiring rights to future sales income of products. This contractual modality, called risk-sharing partnership, is the focus of this study. Specifically, it analyzes the risk-sharing partnerships made by Embraer during the projects of the ERJ-170/190 family of aircrafts. It also aims to justify these partnerships, considering the current global aircraft market conditions, evaluating the critical success factors, requirements and macro-economic conditions which supported the adoption of this new policy.
White-water rafting guides, leisure behaviour and liminality

Tourism, leisure studies, sociology and psychology are some of the academic fields that in recent years have included research related to adventure activities. However, there is still a lack of studies about adventure guides: their personalities, responsibilities and lifestyle. This study aimed to understand the leisure behaviour of white-water rafting guides and the concept of liminality. Exploratory research with white-water rafting guides in Queenstown, New Zealand, was conducted using as methods of data collection twenty-two in-depth interviews and fifty days of participant-observation. Findings show that the relationship between rafting guides goes beyond the workplace, permeating their social and leisure environment thereby creating liminal states and a ‘liminal-style’. Data also revealed that the relationship between guides and clients is not limited to the rafting environment and sexual encounters between these two groups are recurrent. Finally, the excessive alcohol consumption observed during white-water rafting guides’ leisure activities stimulating a discussion about deviant behaviour as well as the different moral and ethical codes present in their non-ordinary lifestyle.
Integrated Modelling of the Impact of Direct and Indirect Taxes Using Complementary Datasets

Comprehensive modelling of the impact of taxes and tax policy options requires data on the impact at micro-level of both direct and indirect taxes. With some exceptions, most national expenditure surveys are not suitable for use in detailed modelling of the direct tax and welfare system. This makes approaches that impute expenditure data into detailed income surveys of considerable interest. Using a commonly applied method of imputing expenditure data into an income survey, this paper examines the degree of sensitivity in the distribution of household expenditure, and following that the distributional impact of indirect taxes, as the analysis moves from being based on actual expenditure data as recorded in the Irish Household Budget Survey (HBS), to being based on expenditure data imputed to the Irish Survey on Income and Living Conditions (SILC). Most sensitivity is found in the estimation and imputation of expenditure data for the bottom income decile. Nonetheless, the imputation process is shown to produce highly comparable distributional results when compared with actual expenditure data. An application of an indirect tax microsimulation model integrated with SWITCH, the ESRI tax-benefit microsimulation model, examines the distributional effects of simultaneous reforms of the direct tax, indirect tax, and social welfare systems, illustrating the analytical capability of the approach tested here.
Kava as a Pharmacotherapy of Anxiety Disorders: Promises and Concerns

Current standard pharmacotherapies for anxiety management come with a host of side-effects that may deter the patients from utilizing them. Kava, a traditional beverage from the South Pacific region, has been used as a natural medicine for centuries and has been hypothesized to contain anxiolytic properties. There are a few well-designed, randomly controlled trials that have evaluated the effectiveness of kava or its constituents against anxiety disorders. They have generally shown kava to be effective in managing the disease. However, there has been a serious concern about the hepatotoxic risk of kava, which greatly limits its anxiolytic development and application. This review attempts to summarize the recent anxiolytic trials using kava, the associated hepatotoxicity risks, the potential responsible chemicals for these two activities, and the mechanisms of action. Overall, kava has a great potential to be developed as a natural anxiolytic agent through a systematic approach, but the present form should be used with caution.
Large Amplitude Oscillatory Shear of the Prandtl Element Analysed by Fourier Transform Rheology

Abstract This work contributes to the theory of strain controlled large amplitude oscillatory shear (LAOS) as well as modelling the key properties of type III behavior of Hyun, the decreasing storage modulus and a loss modulus with considerable maximum. The latter two can be modelled with the help of the Prandtl element. Since it is a yield stress fluid, the use of LAOS is necessary to calculate the storage and loss modulus. Furthermore, a condition is presented which has to be met in order to avoid even harmonics. The storage and loss modulus as well as the higher harmonics of the Prandtl element are determined analytically in this work. They are given as mathematical functions which can be discussed conveniently. This allows the identification of characteristic points which are related to material parameters of the Prandtl element and enable a physically motivated material parameter identification. Beside this, it is observed that the yield strain do not coincide with the crossover G’(ŷ) = G’’(ŷ) but with the increasing of the loss modulus and the decreasing of the storage modulus. Thanks to the analytical calculations, it is also obvious that the stress response of yield stress fluids does not necessarily include even harmonics. In this work the steady state stress response of the Prandtl element is also presented as Lissajous plots and Pipkin diagrams to visualise the rheological fingerprint.
How Can Semantic Annotation Help Us to Analyse the Discourse of Climate Change in Online User Comments

User comments in response to newspaper articles published online offer a unique resource for studying online discourse. The number of comments that articles often elicit poses many methodological challenges and analyses of online user comments have inevitably been cursory when limited to a manual content or thematic analysis. Corpus analysis tools can systematically identify features such as keywords in large datasets. This article reports on the semantic annotation feature of the corpus analysis tool WMatrix which also allows us to identify key semantic domains. Building on this feature, I introduce a novel method of sampling key comments through an examination of user comment threads taken from The Guardian website on the topic of climate change.
Noninvasive measurement of relative bloodoxygen saturation in human retina by using1μm Fourier Domain Optical CoherenceTomography

The relative blood oxygen saturation measurement has been done in human retina by using Fourier Domain Optical Coherence Tomography (FDOCT) data. A broadband (120 nm bandwidth) light source with central wavelength, 1060 nm was used in FDOCT for deeper penetration in retina. A least squares method was implemented to extract oxy and de-oxy haemoglobin concentrations from the FDOCT data. The measured blood oxygen saturation levels in an artery and veins are comparable with existing methods. Thus, this technique can be used to measure in-vivo relative blood oxygen saturation non-invasive way.
A Compact Microstrip Lowpass Filter with Ultra-Wide Rejection Band and Sharp Transition Band Utilizing Combined Resonators with Triangular Patches

In this paper, a microstrip lowpass filter with –3dB cut-off frequency of 1.8 GHz consisting of two resonators with different triangular patches and four high-low impedance resonators as suppressing cells has been designed. To design this filter, the influence of each transmission line on the frequency response of the utilized resonators has been clarified by calculating the equations of S21 and S11 based on the lumped circuit of them separately. The designed filter has been constructed and tested, and a good agreement between the simulation and measurement results has been achieved. The stopband covers an ultra-wide frequency range from 1.94 to 34.556 GHz with a suppression level of –21.2 dB. Furthermore, the insertion loss in the passband region is close to zero from DC to 1.68 GHz and an acceptable return loss (17.44 dB) in this band can prove desired in-band character. Moreover, the proposed filter provides a sharp transition band equal to 228 dB/GHz. The designed lowpass filter has a high figure of merit equal to 26583.4.
A middle time recognition of epileptic seizures from geometrical patterns of EEG data

An approach for middle- time recognition of epileptic seizures from EEG data is proposed. The method considers sharp changes in the recorded data using geometrical patterns of the signal in phase-space. The approach was developed using experimental clinical EEG data recorded from ten patients and reliably predicted epileptic seizures in the ten-minute interval before the seizure onsets. An estimation of sensitivity and specificity of the proposed method is also provided.
Lay Down Simulation of Viscoelastic Fluids Using the Hybrid Immersed-Boundary Method

Lay down of viscoelastic fluids is common in several manufacturing processes. In the automotive industry, sealing material is sprayed onto the vehicle body to prevent water leakage into cavities and to reduce noise. To predict the deposition and lower the environmental impact by reducing material consumption, a detailed physical understanding of the process is important. In this work the resulting surface multi-phase flow is modeled and simulated in IBOFlow, the in-house multi-phase flow solver at the Fraunhofer-Chalmers Centre. In the solver the two phase flow is modelled by the volume of fluid method and the viscoelastic fluid by a general Carreu rheology model. In the solver the scanned or CAD geometry is handled by the hybrid immersed boundary method and the material interface is resolved by the adaptive anisotropic octree grid. The resulting hanging octree and triangular nodes along the geometry are automatically handled by the immersed boundary method. To boost the computational performance the simulation domain is in a novel way dynamically divided into an active and an inactive part. The governing equations are only assembled and solved for in the active part, which is determined by the local position of the injection nozzle. The interface between the active and the inactive cells are handled by symmetry boundary conditions and the pressure is always set for a point inside the active domain. The sealing lay down simulation is successfully validated for a number of real sealing beads on a plate and on a Volvo V40 vehicle. Finally, the importance of resolving the nozzle in the simulation is investigated for a static case.
Nutritive signi¢cance of crystalline inclusion proteins of PhotorhabdusluminescensinSteinernemanematodes

Phase I cells of Photorhabdus luminescens produce two types of intracellular crystalline inclusion proteins designated CipA and CipB. The genes encoding CipA and CipB proteins from P. luminescens H06 were expressed respectively in Escherichia coli and these cells were used to feed the axenic ﬁrst juveniles (J1) of three Steinernema nematode isolates in liquid cultures and on agar plates. In liquid cultures, the axenic J1 juveniles of all three test Steinernema nematode isolates were able to produce next dauer juveniles (DJs) in the E. coli cultures with at least one of the expressed Cip proteins, but unable to develop beyond the next J1 stage without expressed Cip proteins. For each target nematode isolate, addition of the supernatant of the bacterial culture of its Xenorhabdus symbiont to the tested liquid cultures did not induce the formation of DJs. However, on LB agar plates with different test E. coli cultures, all J1 juveniles of the three Steinernema strains ﬁnally developed into next DJs. It seemed that the metabolite pathway of the test bacteria in both culture systems was different. The presence of the Cip has signiﬁcant on the formation of the nematodes liquid culture nematodes in liquid and on plates.
