Interest Rate Channel of Monetary Transmission Mechanism: Evidence from Nigeria

The interest rate channel of monetary transmission is the link through which variations in Central Bank real interest rates influence aggregate output and prices. To check fluctuation in prices, the Central Bank of Nigeria has kept the monetary policy rate stable at 12 percent for the past three years with the view that stability in interest rates will provide the needed incentive for domestic investment to thrive. The long run linkage between real interest rates, inflation and output in a developing country like Nigeria calls for empirical investigation. This study tests the interest rate channel of monetary transmission in Nigeria to enable us establish the extent of stickiness in interest rates in realizing macroeconomic policy goals. The study made use of co-integration and error correction mechanisms in investigating the channel through which nominal interest rates influence long run economic aggregates. The study made use of secondary time series data with quarterly frequency from Q1:1996 to 2013:Q3. Results obtained would help track the speed with which monetary policy changes transmits to the economy and the speed of adjustment from the short run to the long run.
Listeria monocytogenes in mussels (Mytilus galloprovincialis) harvested from North Aegean coastal area

One hundred and two samples of mussels (Mytilus galloprovincialis), harvested from approved shellfish coastal water in northern Greece, were screened for the presence and antimicrobial resistance of Listeria monocytogenes. Listeria spp. were isolated according to International Organization for Standardization method 11290-1: 1996/FDAM 1: 2004(E) and identified using a multiplex polymerase chain reaction (PCR) system. The serovar identity of L. monocytogenes isolates was also determined with a multiplex PCR assay. The antimicrobial profile of the isolates was determined by the disk diffusion method. Listeria spp. were present in 8 of 102 samples tested (8%) and only 1 (1%) yielded L. monocytogenes. The isolate identified as L. monocytogenes was defined as serogroup I and found to be resistant to nalidixic acid and streptomycin. In conclusion, this study demonstrated that L. monocytogenes is not commonly found in mussels harvested in the North Aegean Sea, whereas there is a higher possibility of mussels’ contamination with other Listeria species.
Design A Flexible Antenna Integrated With Artifical Magnetic Conductor

A flexible printed monopole antenna integrated with artificial magnetic conductor (AMC) working at 2.45 GHz is designed and analyzed. The proposed antenna is suitable for the industrial, scientific, and medical (ISM) band, WIFI and Bluetooth applications. The artificial magnetic conductor (AMC) is used to enhance the antenna characteristics and to isolate the antenna from human body effects that produces by proximity coupling. The antenna has ultra-low profile which is about $0.028 \lambda0$. The simulated results show a good improvement in gain from 0.82 dB to 2.61 dB, efficiency from 78.56% to 88.72% and the radiation pattern change from omni-direction to uni-direction which it suitable for wearable applications.

Energy Efficiency and Reliability in Underwater Wireless Sensor Networks Using Cuckoo Optimizer Algorithm

Energy efficiency and reliability are widely understood to be one of the dominant considerations for Underwater Wireless Sensor Networks (UWSNs). In this paper, in order to maintain energy efficiency and reliability in a UWSN, Cuckoo Optimization Algorithm (COA) is adopted that is a combination of three techniques of geo-routing, multi-path routing, and Duty-Cycle mechanism. In the proposed algorithm, by presenting a cost function in COA algorithm, a hop-by-hop method of route selection is performed using power consumption and energy content of the current node; while in Greedy Geographic Forwarding based on Geospatial Division (GGFGD) algorithm, data transfer is based on the closest route to a destination criterion. Simulation results show that despite the increase in path lengths and the resulting increase in propagation delay, the remaining energy of the UWSN increases using the proposed technique compared to GGFGD algorithm. Besides, we will show that while improving energy consumption, the number of paths found and, therefore, reliability of the network in the proposed method that uses duty-cycle mechanism are higher than the ones in GGFGD algorithm.
Students Academic Counseling from Attribute Precedence Relations using EDM

— Educational Data Mining (EDM) techniques play an important role in understanding hidden students’ data patterns to improve the quality of teaching-learning professions. In machine learning, feature selection usually emerges as a preprocessing step to extract necessary and sufficiently small subset of features for predictive / decision-making type of learning tasks. In this study, authors decided to work only upon external (changeable) attributes of students by assigning weights that reflect their academic efforts put in for those attributes. The attribute precedence levels extracted student-wise by current FE model due to academic efforts put up by students in their on-going course were compared with equivalently generated precedence relations from RELIEF method and it’s variant. The favorable model accuracies of these precedence relations when compared with RELIEF have given a new meaning to EDM objectives in the direction of individual student counseling encouraging them to appraise themselves amidst their course tenure in right direction.
Narratives of Puerperal Women about Pregnancy and Risk Prenatal Care

INTRODUCTION: Pregnancy is a physiological phenomenon and therefore its evolution usually occurs uneventfully. However, it can pose risks for both the mother and the fetus and there are a number of women who, due to particular characteristics, are more likely to unfavorable evolution, which are called high-risk pregnancies. Therefore, this study aimed to know, from the narratives of mothers discharged from the Intensive Care Unit, the main doubts and complaints about pregnancy and risk prenatal care and describe the therapeutic itinerary throughout pregnancy. METHOD: Descriptive, qualitative study conducted in the homes of mothers enrolled in basic health services of the 4th Regional Unit in Fortaleza, Ceara, Brazil, from January to February 2015. A total of 10 mothers participated through narrative interview technique. For data analysis, authors adopted the proposal by Gomes and Mendonca and Gomes. RESULTS AND DISCUSSION: Questions were directed to the pathology. The difficulties in the consultation were inadequate communication, focus on disease, difficulty in following guidelines and lack of explanations aimed at childbirth, nutrition, breastfeeding, later childcare and insufficient emphasis on emotional aspects. In addition, there were difficulties along the therapeutic path. CONCLUSION: It was noted the importance of carrying out actions / strategies that enable the realization of a resolute care.
UWB diversity performance in correlated lognormal- sum-distributed in-body to on-body channel

Ultra wideband (UWB) technology in low band has being attracted considerable attention for high-speed and real-time transmission from inside to outside human body. However, it suffers from large attenuation and shadow fading in human tissues. A diversity technique is expected to provide effective improvement on its communication performance. This study aims to derive an approximate model for correlated in-body to on-body diversity channel and clarify the diversity effect. First, correlated statistical distribution between each two single signals is approximated as a lognormal sum distribution. Then two flexible parameters s1 and s2 in the lognormal sum approximation are optimized to obtain the probability density function (PDF) of the diversity channel. Finally the average bit error rates (BERs) are calculated theoretically to clarify the diversity effect, and its validity is verified by computer simulations.
The relationship between interest rates and sovereign ratings: An analysis using a Markov-switching model

In this paper, the correlation between the evolution of credits’ interest rate and sovereign rating was analysed. In order to capture this view, a Markov-switching approach was engaged to model the transition probabilities of low and high volatility regimes for interest rate. Also, the official rate of inflation and the amount of domestic credit denominated in lei were used as explanatory variables. The results of vector autoregressive approach revealed interesting interactions between the three macro variables, with interest rate being explained by both inflation rate and domestic credit. For the fact that the sovereign rating denotes a qualitative measure provided without a regular frequency, but which incorporates some subjective aspects, it was proposed as an indicator function to account for the sovereign ratings downgrades. Thus, to observe the relation between interest rate and sovereign rating, the transition probabilities of switching regimes for interest rate with the values of the indicator function mentioned before was correlated. Key words: Markov-switching model, VAR, indicator function, rating, credits’ interest rate, inflation rate, domestic credit.
Tilted anisotropic Dirac cones in quinoid-type graphene and α-(BEDT-TTF) 2 I 3

We investigate a generalized two-dimensional Weyl Hamiltonian, which may describe the low-energy properties of mechanically deformed graphene and of the organic compound $\ensuremath{\alpha}\text{\ensuremath{-}}{(\text{BEDT-TTF})}_{2}{\text{I}}_{3}$ $[\text{BEDT-TTF}=\text{bis}(\text{ethylene}\text{dithio)tetrathiafulvalene}]$ under pressure. The associated dispersion has generically the form of tilted anisotropic Dirac cones. The tilt arises due to next-nearest-neighbor hopping when the Dirac points, where the valence band touches the conduction band, do not coincide with crystallographic high-symmetry points within the first Brillouin zone. Within a semiclassical treatment, we describe the formation of Landau levels in a strong magnetic field, the relativistic form of which is reminiscent of that of graphene, with a renormalized Fermi velocity due to the tilt of the Dirac cones. These relativistic Landau levels, experimentally accessible via spectroscopy or even a quantum-Hall-effect measurement, may be used as a direct experimental verification of Dirac cones in $\ensuremath{\alpha}\text{\ensuremath{-}}{(\text{BEDT-TTF})}_{2}{\text{I}}_{3}$.
Gender differences in introductory undergraduate physics performance: University physics versus college physics in the USA

Efforts to ameliorate gender disparity in pursuit of science careers in the USA have focused on equalizing girls' participation in pre-college science courses and out-of-school activities. Our examination of nearly 1500 US college students at 16 universities found that gender and preparation both have an impact on success in introductory college physics courses. In terminal, algebra-based physics females perform better than their male classmates. However, in calculus based introductory college physics courses, which are prerequisite to advanced study in many fields, women do significantly worse than their male counterparts with the same background. For both genders, taking a high school course that limits coverage and concentrates more time in in-depth study is associated with better performance in college physics. We conclude that efforts to ensure the success of women entering the physical sciences should concentrate on increasing the depth and reducing the vast coverage of most high school physics courses as well as addressing the apparent bias in college courses that mark the first step in careers within scientific research and engineering.
Psychological empowerment in French nuclear power plants

Since the eighties, nuclear safety has been discussed in organizational studies and constitutes nowadays a specific stream with several standpoints. Regarding the reliability of nuclear plants, the nuclear safety literature has emphasized on the crucial role of individuals and human factors. Especially, some researchers have noticed rule breaking behavior and the impact of individual self-confidence on thebehavior; but without deepening their analyses. As high self-esteem and confidence, i.e. psychological empowerment, naturally lead to innovation and rule breaking, the behavior can be analyzed, in such a regulated industry, as opposite to safety. Thus, this article aims at explaining the roots and discernable features of the observed psychological empowerment. Methods include an in-depth qualitative study in 4 nuclear power plants owned by Electricite de France (EDF), the French national nuclear operator. Focused on the leading team of the plant, the set of data is composed of 35 interviews, 6 weeks of non-participant observation and internal documents. The content analysis has revealed two main pillars of psychological empowerment. On the first hand, the strong professional identity developed at the opening of the plants is based on initiative and risk-taking. In some ways, this professional identity fostered by commitment to a demanding job and the team, influences behavior more than do professional rules. On the second hand, the management discourse is perceived as ambiguous towards the strict application of the rules and tacitly legitimizes rule breaking behavior. This article details and exemplifies these phenomena and discusses the implications.
Testing for measurement equivalence of individuals’ left-right orientation

Subjective variables such as opinions, attitudes or preferences cannot be measured directly. Researchers have to rely on the answers people give in surveys, and whenever those answers shall be compared it is required that people answer these questions in the same way. Only then a concept can be used in different contexts. This paper deals with the measurement of the left-right concept: it analyses whether people make a distinction between a scale labelled 0 left and 10 right to one which is labelled 0 extreme left and 10 extreme right and tests whether the instrument is equivalent across groups. Following the three steps of invariance testing, configural, metric and scalar invariance, we find that the left-right response scale is on average equivalent across groups with different levels of political interest and different levels of education. This finding holds also in 23 of the 25 European countries tested, with the exception of the eastern part of Germany, Finland and France. In order to estimate how serious the difference between these two groups of countries is, we compare the observed means (which are affected by the difference) to the latent means (which are free of those effects), and the effect of the observed variable “attitude towards government’s intervention in the economy” on the observed variable “left-right self-placement” with the effect between these variables after correcting for scale difference. It was found that countries’ means can be compared but that the relationship with other variables might not be comparable among East Germany, Finland, France and the remaining countries.
Does Rapid Economic Growth Accelerate Democratization ? Time-Series Evidence from High Performing Asian Economies

We examine the direction of causality between growth and democratization for the high performing Asian economies using a new time-series technique called autoregressive distributive lag. We find that for all eight of such economies, the direction of causality runs consistently from democratization to growth and not the other way around. Rapid growth in the high performing economies appears to have little effect on democratization. We also find that the net effect of democratization on growth is not always positive. Against the widely-held view that growth enhances democratization, our evidence suggests that rapidly developing countries under authoritarian rule are unlikely to improve their democratic institutions.
LAYOUT OF THE USR AT FLAIR

The Facility for Low-energy Antiproton and Ion Research (FLAIR) and a large part of the wide physics program decisively rely on new experimental techniques to cool and slow down antiprotons to 20 keV, in particular on the development of an ultra-low energy electrostatic storage ring (USR). The whole research program connected with anti-matter/matter interactions is only feasible if such a machine will be realized. For the USR to fulfil its key role in the FLAIR project, the development of novel and challenging methods and technologies is necessary: the combination of the electrostatic storage mode with a deceleration of the stored ions from 300 keV to 20 keV, electron cooling at all energies in both longitudinal and transverse phasespace, bunching of the stored beam to ultra-short pulses in the nanosecond regime and the development of an in-ring reaction microscope for antiproton-matter rearrangement experiments. In this contribution, the layout and the expected beam parameters of the USR are presented and its role within FLAIR described.
Switching Volatility in Emerging Stock Markets: Evidence from the New EU Member Countries

In this paper, we use weekly stock market data to examine whether the volatility of stock returns of ten emerging capital markets of the new EU member countries has changed as a result of their accession in the EU. In particular we are interested in understanding whether there are high and low periods of stock returns volatility and the degree of correlation across these markets. We estimate a Markov-Switching ARCH (SWARCH) model proposed by Hamilton and Susmel (1994) and we allow for the possibility that three volatility regimes may exist for stock returns volatility. The main finding of the present study is that the high volatility of stock returns of all new EU emerging stock markets is associated mainly with the 1997-1998 Asian and Russian financial crisis while there is a transition to the low volatility regime as they approach the accession to EU in 2004.
