Rand volatility and inflation in South Africa

The floating exchange rate regime, coupled with a more open trade policy and the growth in imports, leaves South Africa vulnerable to the effects of exchange rate behaviour on import, producer and consumer prices, which all contribute to inflation. Given the central role that inflation targeting occupies in South Africaâ€™s monetary policy, this paper examines the effect of exchange rate shocks on consumer prices using monthly data covering the period January 1994 to December 2013. Consistent with developing countries story, results show a modest exchange rate pass-through to inflation, although inflation is mainly driven by own shocks. The variance decompositions also reveal that foreign exchange rate shocks (REER) contribute relatively more to inflation than money supply shocks (M3). This suggests that South African inflation process is not basically influenced by money supply changes. The practical implication is that that the volatility of the rand is not a serious threat to inflation. The SARB should therefore focus on price stability and not be unduly worried about the volatility of the rand.
Obesity is Associated with More Sick Leave and Lower Quality of Life Among Malay Male Security Officers

Obesity is a risk factor for chronic diseases which can affect work productivity and physical function of employees particularly among those in security sector. The study aimed to determine the association between obesity with total days of sick leave and health related quality of life (HRQoL) among Malay male security officers. A cross-sectional study was conducted among Malay male security officers working in a Malaysian higher learning institution. Subjects were evaluated using anthropometric measurements, quality of life and number of sick leave taken within two months prior to the study. A total of 194 subjects (mean age 40.12 ± 11.41 years) were recruited. A total of 30.4% were obese, 39.7% were pre-obese and only 29.9% had normal body weight or underweight. Central obesity was observed in 57.7% of them and 87.1% shown excessive body fat percentage. Number of sick leave days was positively correlated with Body Mass Index (BMI) (r = 0.162, p = 0.024) and waist circumference (r = 0.181, p = 0.012). Score of the general health component was negatively correlated with BMI (r = -0.161, p = 0.025), waist circumference (r = -0.194, p = 0.007) and body fat percentage (r = -0.191, p = 0.008). Physical functioning score was lowest in obese subjects than normal and pre-obese subjects (p = 0.046). Score of the bodily pain component was positively correlated with waist circumference (r = 0.156, p = 0.030). Obesity is associated with number of sick leave days and quality of life in the studied group. Hence, body weight of the security staff should be monitored and appropriate intervention should be conducted to improve their work attendance and quality of life.

Energy Efficient Design Strategies of Translucent and Transparent IP Over WDM Networks

A surge of interest toward design and implementation of green networks are emerging in recent years. One obvious trend to reduce energy consumption of major active network components is to craft backbone network architecture that takes into consideration traffic grooming of low-rate IP traffic as well as power-aware virtual topology design schemes and RWA. Previous research efforts developed design strategies which assumed digital processing of incoming traffic flows at every node structure in the optical layer (DXCs). This architecture provides full wavelength conversion capability by the use of optical transponders (OEO convertors) thus reduces complicated RWA problem to a simple routing problem at the cost of sacrificing lightpath transparency. Moreover, introduction of transponders give rise to extra sources of power consumption which contrasts over goal. In this paper, energy-minimized design of IP over WDM networks based on optical cross connects (OXCs) is investigated. Integer linear programming formulation as well as heuristics for two design strategies viz. multi-hop lightpath and direct bypass have been developed and their performance with regard to power consumption and relative bandwidth utilization are compared. Simulation results indicate superior performance of the proposed strategies with regard to previous studies.
The fundamental construction in the social investment of inter- organization

The concept of social investment has been recently represented in the fields of social, economical and managerial sciences in the recent years. It is obtained by the reaction based on conscious and bilateral recognition of staffs into the whole organizations and its final result is an endless struggle being applied commonly to organize the most sustainable relations and benefits between the related parties potentially. This concept showing its own representing power has been established rapidly into the scientific places and many various studies have been also carried out in this field increasingly. Along this, the present study is to give and represent a model of social investment of inter-organization in the University of Khoy. The related study has been carried out as a scale-descriptive method and its data gathering method was a questionnaire. The obtained results of the study showed that the function of management, organizational field, managerial behavior and channel-based communications and bonds are the main factors of inter-organization social investment formation in Islamic Azad University of Khoy.
Efficient carbonaceous sorbent based on the waste sludge of oil extraction industry for purifying wastewater from petroleum products

The opportunity to use the oil extraction industry waste kieselghur sludge as a raw stuff for carbonaceous sorbent for purifying wastewater from petroleum and petroleum products has been researched. It has been demonstrated that the thermal modification of the waste sludge results in oxidation of organic matter and the formation of a carbon layer on the surface of kieselghur (diatomite), as well as the formation of the obtained material’s porous structure. The maximum values of oil-absorption and petroleum-absorption of the carbonaceous sorbent samples, obtained at various temperatures of the initial waste product treatment, have been determined. The highest petroleum saturation (2 g/g) is observed in the first 5 minutes of the sorbent’s contact with the pollutant and is characteristic of the material, obtained at temperature 500°С. The highest oil saturation (3.6 g/g) is shown by the sorbent, obtained at temperature 450°С. This value was achieved after 30 minutes of the sorbent’s contact with oil. The efficiency of clarifying water-oil emulsion with the concentration 1.5 g/dm by using carbonaceous sorbents of various thermal pre-history has been determined. The highest degree of emulsion clarification – 91% was achieved at using the sorbent, obtained as a result of the waste sludge modification at temperature 450°С.
Universal Gröbner Bases for Designs of Experiments

Universal Grobner bases (UGB) are a useful tool to obtain a set of different models identified by an experimental design. Usually, the algorithms to obtain a UGB for the ideal of a design are computationally intensive. Babson et al. (2003) propose a methodology to construct UGB in polynomial time. Their methodology constructs a list of term orders based upon the Hilbert zonotope. We focus on the generation of such a list. We use results on hyperplane arrangements to present a theorem which simplifies the computation of term orders for designs in two dimensions. Our theorem constructs directly the normal fan of the Hilbert zonotope.
How Objective a Tool is Teacher Licensure Testing?

Virtually all states require teacher candidates to undergo licensure testing as a prerequisite to participation in the public school teacher labor market. This paper analyzes how these tests function in providing information about the effectiveness of teachers. In our analysis using a dataset of public school teachers and their students in North Carolina spanning ten years, we find both black teachers and male teachers have substantively lower performance on these licensure tests but have few differences in classroom performance. Further, we find performance on the tests does not uniformly predict classroom effectiveness for all teacher demographics. Additionally, we analyze the interactions between teacher and student race and gender, holding licensure test performance constant. This analysis suggests that black students, in particular, benefit from having a black teacher. These positive mentoring effects are benefits that may be lost if the state were to pursue policies that strictly enforce licensure cutoffs.
Use of New Supplement Feeds Based on Organic Iodine in Rations of Lactating Cows

2 Abstract: The aim of the study is to investigate the influence of the organic iodine-based supplement feeds on the milk producing ability and to examine the extent of the organic iodine transition into the raw milk and its products. The research has found that by adding the studied agent to the ration the milk producing ability of the experimental cows raised by 7,8-10,9% compared to control animals. The values of milk quality indexes: protein, fat, casein, lactose have also increased. The cows in the experimental group (compared with the cows in the control group) have shown the tendency to increase the amino acid content in milk, including key amino acids by 0.107 and 0.084%, respectively and nonessential amino acids by 0.042 and 0.056%. The concentration of iodine has also increased in dairy raw materials and refined products by 36.1 and 35.7%.
Clinical comparative study between Magnesium sulphate versus Rocuronium versus Dexmedetomidine as adjuvants for local anesthetic in peribulbar block for eye surgeries

Background: Regional anesthesia is a preferred technique for ophthalmic surgery. It is safe, inexpensive and provides efficient ocular anesthesia for ophthalmic surgery. It is associated with less hemodynamic instability, less respiratory depression, better postoperative pain relief, and less nausea and vomiting compared to general anesthesia. Objectives: The aim of the study was to compare the safety and efficacy of the use of Magnesium sulfate versus that of Rocuronium versus Dexmedetomidine as an adjuvant to the local anesthetic in peribulbar anesthesia. It is characterized by generating optimal operating conditions for eye surgery in terms of akinesia, analgesia, incidence of complications, as well as induction of patient and surgeon satisfaction. Patients and Methods: The present study included100 patients of the American Society of Anesthesiology (ASA), physical status I, II, III or IV of both sex, (20-80) years old and undergoing to anterior and posterior segment surgeries. Informed written consent from all patients was taken after approval of Al-Azhar University Ethical Committee. Results: Evaluation of the globe akinesia was done at (2.5),(5),(7.5),and(10) min. after injection. The onset of motor block showed a statistically significant difference between the four groups, the rocrounium group showed more rapid onset of motor block then dexmedtomedine group then magnisum sulphate group then lastly the control group. Conclusion: The present study concluded that using Rocuronium as an additive to local anathestic drugs in peribublar block it makes onset of block more rapid and dense but it has less effect on analgesic aspect. On the other hand, when Dexmedetomidine or Magnesium sulfate were used as additive they increased analgesic effect of local anathestic and decreased the need for early postoperative rescue analgesia, as well as fastening the onset of block but to a lesser extent less than Rocuronium as an additive to local anathestic.
A Unity power factor boost rectifier with a predictive capacitor model for high bandwidth DC bus voltage control

Abstract Single-phase rectifiers with power factor correction circuits based on the boost converter have broad application in consumer equipment. A fundamental design difficultly is caused by the need to trade-off the input line current wave shape and the dynamic response of the output energy storage capacitor voltage regulation loop. The energy balance requirement inherent in single-phase systems forces a significant 100 Hz voltage ripple on the output capacitor. A high bandwidth voltage regulation loop will feed back enough of the 100 Hz component to distort the current reference signals for the inner current control loop distorting the line wave shape. A reference model can be used to construct a ripple-free estimate of the capacitor voltage. This paper shows that improved output capacitor voltage regulation can be achieve simultaneously with a high quality input current spectrum.
Knowledge Management Readiness In Organizations

To generate a comprehensive model of Knowledge Management Readiness In Organizationsintending greater value to its practical applicability. This study was based on both secondary and primary data grounded on the deductive paradigm of social research. Survey with 13 professionals in the current business setting was conducted to justify the research findings. The key criterion of KM Readiness In Organizations, i.e. its dependency on human acts was ignored in many traditional KM models although literary works paid substantial value to the aspect. Applicability of conventional KM models in the current context was also limited. The study lacked consideration to the influence of organizational characteristics on KM practices based on organizational readiness. The number of respondents was also limited for a wide research such as this. As this study was mainly guided by the contemporary beliefs and attributes of organizational management, the developed model is likely to find its worthy applicability in practical experiences. Due emphasis was provided to ethical soundness throughout the paper, confirming its originality and value in terms that anti-plagiarism strictness was taken into context and self-infliction of information was avoided entirely.
EEG source analysis using space mapping techniques

The electroencephalogram (EEG) measures potential differences, generated by electrical activity in brain tissue, between scalp electrodes. The EEG potentials can be calculated by the quasi-static Poisson equation in a certain head model. It is well known that the electrical dipole (source) which best fits the measured EEG potentials is obtained by an inverse problem. The dipole parameters are obtained by finding the global minimum of the relative residual energy (RRE). For the first time, the space mapping technique (SM technique) is used for minimizing the RRE. The SM technique aims at aligning two different simulation models: a fine model, accurate but CPU-time expensive, and a coarse model, computationally fast but less accurate than the fine one. The coarse model is a semi-analytical model, the so-called three-shell concentric sphere model. The fine model numerically solves the Poisson equation in a realistic head model. If we use the aggressive space mapping (ASM) algorithm, the errors on the dipole location are too large. The hybrid aggressive space mapping (HASM) on the other hand has better convergence properties, yielding a reduction in dipole location errors. The computational effort of HASM is greater than ASM but smaller than using direct optimization techniques. © 2007 Elsevier B.V. All rights reserved.
Attitudes to Uncertainty in a Strategic Setting

Much uncertainty in life relates to the behaviour of others in interactive environments. This article tests some implications of subjective expected utility theory (Savage, 1954) in an experimental strategic setting where there is uncertainty about the actions of other players. In this environment, a large majority of our participants violate subjective expected utility theory. However, they do not exhibit the sorts of consistent ‘attitude to ambiguity’ found in individual decision experiments. We discuss three possible explanations of their behaviour: non-linear transformation of probabilities; noise in responses; and/or systematic biases in the way that individuals generate subjective probabilities.
ANOMALOUS ORIGIN OF PALMARIS LONGUS MUSCLE - CASE REPORT

Palmaris longus is one of the most variable and most superficial flexor muscles of the forearm. Its absence appears to be hereditary but genetic transmission is not clear. An understanding of its variations is useful as it is often used as tendon graft and for tendon transfer as well as in other reconstructive procedures like ptosis correction, lip augmentation and management of facial paralysis. Therefore, all possible variations in the important muscle should be well known. We report here a variant pattern of origin of palmaris longus, and its probable significance. So, any variation of the palmaris longus is gaining importance as it is becoming very popular amongst graft material for reconstructive surgeries. During routine dissection of the flexor compartment of the forearm on the right side, we found variation in the origin of palmaris longus muscle. However, similar variation was not observed on the contra-lateral side. Knowledge of this variation is important not only for anatomist but also for surgeons, because of its close relation to the median nerve. Therefore, an attempt has been made to highlight its clinical significance.
Genomic signatures of positive selection with respect to the immunity-related genes in cattle

The aim of this study was to detect genomic regions that have been target of positive selection and to identify markers responsible for immune response across two local cattle breeds. In total of 189 animals representing the nucleus of Slovak Pinzgau and Slovak Spotted populations were included in to the study. All of animals have been genotyped by using Illumina BovineSNP50 v2 Bead chip. In order to obtain more detailed view on genomic regions controlling adaptive and innate immune response only SNPs located on BTA6 (1.7287.76 Mb), BTA21 (6.1-71.59 Mb) and BTA23 (6.98-30.50 Mb) were selected. Overall 3,250 SNPs were retained in reduced panel of markers. In order to identify genomic regions under selection pressure, the PCA approach was used based on the assumption that loci extremely related to the population structure will also candidates associated local adaptation of the population. Based on the false discovery rate equal to 10 % up to 213 loci were identified as outliers. Most of them were found on BTA6 (118) in the two genomic regions within sequence of genes encoding Toll-like receptors (TLR1, TLR6, TLR10) and Immunoglobulin J chain (RBPJ). On BTA21 the strongest signal was detected directly within sequence of immunoglobulin superfamily (ISLR, ISLR2). The lowest proportion of outlier loci was found on BTA23 (13) mostly within region controlling Major histocompatibility complex (MHC). Our results indicated that the signals of selection in genomic regions responsible for adaptive and innate immune response across both cattle breeds resulted mainly from the correlated selection response associated with maintaining their fitness. Compared to conventional breeds, the allele frequency differences can be expected in identified genomic regions. In the future, genetic selection for animals characterized by better immune response to environmental condition and diseases can provide health and productivity advantages and complement traditional health-maintenance methods.
Properties of hypermassive neutron stars formed in mergers of spinning binaries

We present numerical simulations of binary neutron star mergers, comparing irrotational binaries to binaries of NSs rotating aligned to the orbital angular momentum. For the first time, we study spinning BNSs employing nuclear physics equations of state, namely the ones of Lattimer and Swesty as well as Shen, Horowitz, and Teige. We study mainly equal mass systems leading to a hypermassive neutron star (HMNS), and analyze in detail its structure and dynamics. In order to exclude gauge artifacts, we introduce a novel coordinate system used for post-processing. The results for our equal mass models show that the strong radial oscillations of the HMNS modulate the instantaneous frequency of the gravitational wave (GW) signal to an extend that leads to separate peaks in the corresponding Fourier spectrum. In particular, the high frequency peaks which are often attributed to combination frequencies can also be caused by the modulation of the $m=2$ mode frequency in the merger phase. As a consequence for GW data analysis, the offset of the high frequency peak does not necessarily carry information about the radial oscillation frequency. Further, the low frequency peak in our simulations is dominated by the contribution of the plunge and the first 1--2 bounces. The amplitude of the radial oscillations depends on the initial NS spin, which therefore has a complicated influence on the spectrum. Another important result is that HMNSs can consist of a slowly rotating core with an extended, massive envelope rotating close to Keplerian velocity, contrary to the common notion that a rapidly rotating core is necessary to prevent a prompt collapse. Finally, our estimates on the amount of unbound matter show a dependency on the initial NS spin, explained by the influence of the latter on the amplitude of radial oscillations, which in turn cause shock waves.
Hyperspectral detection and discrimination using the ACE algorithm

One of the fundamental challenges for a hyperspectral imaging system is the detection and discrimination of subpixel objects in background clutter. The background surrounding the object, which acts as interference, provides the major obstacle to successful detection and discrimination. In many applications we look for a single signature and discrimination among different signatures is not required. However, there are important applications where we are interested for multiple signatures. In these cases, the use of spectral discrimination algorithms is both necessary and valuable. In this paper, we develop an approach to spectral discrimination based on the adaptive cosine estimation (ACE) algorithm. The basic idea is to jointly exploit the detection statistics from the various signatures and set a common threshold that ensures larger separation between signatures of interest and background. The operation of the proposed detection-discrimination approach is illustrated using real-world hyperspectral imaging data.
