Investigating momentum on the Johannesburg Stock Exchange

The paper examines if stock price momentum is a common trait amongst top performing shares on the Johannesburg Stock Exchange and whether individual investors can harness the relationship of momentum and return to create a profit. The viability of the phenomenon as an investment strategy was gauged by comparing annualised average returns of momentum shares, identified through both technical analysis as well as price performance momentum measures, against the market capitalisation weighted JSE All Share Index as well as against an un-weighted representation of the market. The results revealed a seemingly unmistakable co-dependence between momentum and return, with statistically significant trends being ever present. Applying the maximum taxes and trading costs revealed that the highest ranked momentum shares did indeed outperform both market benchmarks from the period of January 1990 to August 2009, suggesting the validity of the philosophy as an investment strategy.
The dilatancy–diffusion hypothesis and earthquake predictability

Abstract The dilatancy–diffusion hypothesis was one of the first attempts to predict the form of potential geophysical signals that may precede earthquakes, and hence provide a possible physical basis for earthquake prediction. The basic hypothesis has stood up well in the laboratory, where catastrophic failure of intact rocks has been observed to be associated with geophysical signals associated both with dilatancy and pore pressure changes. In contrast, the precursors invoked to determine the predicted earthquake time and event magnitude have not stood up to independent scrutiny. There are several reasons for the lack of simple scaling between the laboratory and the field scales, but key differences are those of scale in time and space and in material boundary conditions, coupled with the sheer complexity and non-linearity of the processes involved. ‘Upscaling’ is recognized as a difficult task in multi-scale complex systems generally and in oil and gas reservoir engineering specifically. It may however provide a clue as to why simple local laws for dilatancy and diffusion do not scale simply to bulk properties at a greater scale, even when the fracture system that controls the mechanical and hydraulic properties of the reservoir rock is itself scale-invariant.
THE INFLUENCE OF PSYCHOLOGICAL EMPOWERMENT ON THE WORK EXHAUSTION AND EMOTIONAL INTELLIGENCE

This research aims to determine the effect of psychological empowerment on the work exhaustion and emotional intelligence on the tour guide in Nusa Tenggara Barat Province, one of the provinces with the highest tourism income in Indonesia. The type of this research is explanatory research with a sample of 150 tour guides, taken from 653 people using stratified proportionate random sampling technique. The data analysis uses two analyses, namely descriptive with the help of SPSS version 20.0 and inferential analysis with Generalized Structured Component Analysis (GSCA). The result of this research shows that there is a negative significant influence between psychological empowerment on the work exhaustion. There is a positive significant influence between psychological empowerment on the emotional intelligence, and there is no significant and negative influence between work exhaustion on the emotional intelligence.
Comparison of DAC-ELISA and Tissue Blot Immunoassay for the Detection of Acidovorax avenae subsp. avenae, causal agent of Red Strip of Sugarcane

Direct Antibody Coating Enzyme Linked Immunoassay (DAC-ELISA) and Tissue Blot Immunoassay (TBIA) were compared for detection of Acidovorax avenae subsp. avenae (Aaa) in sugarcane samples surveyed in 2010 and 2011. A total of 27 sugarcane clones contained two samples of symptomatic plants, which were tested simultaneously by both serological tests. The results obtained from DAC-ELISA tests showed that 11 of 27 tested samples of sugarcane clones were infected with Aaa and 16 were bacteria free; whereas, in duplicate samples only 7 samples were positive for Aaa using the TBIA. The TBIA membranes showed dark blue stain colour in the 7 positive and 20 were negative. It was concluded that the DAC-ELISA had false positives in the 4 clones (SPF-238, CP77-400, SPF-213 and GT-11) that were negative using TBIA. Assay time was also minimized in performing TBIA test as equivalence to DAC-ELISA. Related to the test performing time at least 25-30 hours were consumed for the completion of DAC-ELISA assay, while only 6-9 hours was required for TBIA assay with reliable results. Both assays gave Aaa positive for clones HoSG-315, CPSG-437, NSG-49, CPSG-2453, CP-NIA-82-223, CSSG-2402 and US-114. TBIA tests were distinct with clear positive and negative results having minimum diagnostic error. On the other hand quantitative assay of bacteria is a significant feature of DAC-ELISA but low optical density readings above background were inconsistent with the TBIA and were considered false positive results. Amongst the variety of immunological tests available in Pakistan, tissue blot immunoassay (TBIA) is most useful in detecting latent infections in the plant materials.
The effect of brand, design, and price on intention to purchase mediated by quality perception at sport shoes X

Product cues have been identified as a major factor and are used by customers when they evaluate a product before deciding to buy. Customers evaluate products based on the product manual cues; generally, they use the brand, design and price, and produce quality perception and ceases on purchase intentions. This process also occurs in the prospective buyer's sport shoes X that have the largest sales in Indonesia. Therefore, the researchers are interested to test whether there is a relationship between the product cues on the quality perception and purchase intention for sports footwear products. This research was done by using a survey for the data collection, by distributing the questionnaires to 161 respondents. The data were analyzed using Structural Equation Modeling with Lisrel analysis tool. The result showed that the product cues have an influence mediated by the quality perception on purchase intentions. This study suggests that the perception of quality is as a full mediating variable between products cues and purchase intention.

1 Internet / E-Business Technologies Acceptance in Canada ’ s SMEs : Focus on Organizational and Environmental Factors

Large and small business organizations around the world, including Canadian enterprises, utilize internet and e-business technologies (IEBT) to support online or electronic commerce (e-commerce) and electronic business (e-business) activities. Grandon and Pearson (2004) and Turban et al. (2010) note that IEBT enhances productivity for the adopting organization in the following ways: a) it improves efficiencies through automation of transactions, b) it reduces intermediaries in the value chain to foster greater economic advantages, c) it consolidates demand and supply through organized exchanges, d) it facilitates product improvement as well as engenders innovative ways of selling existing products and services. Against the backdrop of the popularity of IEBT, it is not surprising that several researchers have investigated and continue to study the adoption or acceptance of such technologies in differing contexts and locations (Farhoomand et al., 2000; Wymer & Regan, 2005). Studies that have focused on Canadian businesses are beginning to emerge (Raymond, 2001; Ifinedo, 2011).
Milky Way scattering properties and intrinsic sizes of active galactic nuclei cores probed by very long baseline interferometry surveys of compact extragalactic radio sources

We have measured the angular sizes of radio cores of active galactic nuclei (AGN) and analyzed their sky distributions and frequency dependencies to study synchrotron opacity in AGN jets and the strength of angular broadening in the interstellar medium. We have used archival very long baseline interferometry (VLBI) data of more than 3000 compact extragalactic radio sources observed at frequencies, $\nu$, from 2 to 43 GHz to measure the observed angular size of VLBI cores. We have found a significant increase in the angular sizes of the extragalactic sources seen through the Galactic plane ($|b|\lesssim10^\circ$) at 2, 5 and 8 GHz, about 1/3 of which show significant scattering. These sources are mainly detected in directions to the Galactic bar, the Cygnus region, and a region with galactic longitudes $220^\circ\lesssim l\lesssim260^\circ$ (the Fitzgerald window). The strength of interstellar scattering of the AGNs is found to correlate with the Galactic H$\alpha$ intensity, free-electron density, and Galactic rotation measure. The dependence of scattering strengths on source redshift is insignificant, suggesting that the dominant scattering screens are located in our Galaxy. The observed angular size of Sgr A$^\ast$ is found to be the largest among thousands of AGN observed over the sky; we discuss possible reasons of this strange result. Excluding extragalactic radio sources with significant scattering, we find that angular size of opaque cores in AGN scales typically as $\nu^{-1}$ confirming predictions of a conical synchrotron jet model with equipartition.
Pre-Trade Transparency , Learning Externalities , and Return Co-movements in Commercial Real Estate Markets

This paper proposes an empirical framework that is based on pre-trade transparency to test for information-based return co-movements among international commercial real estate markets. We introduce a benchmark portfolio that includes property markets with a higher pre-trade transparency to assess expected returns in less transparent markets. Investors can earn abnormal returns in opaque markets relative to the reference portfolio. Revealed post-trade information in the benchmark portfolio results in spillover effects to less transparent markets. Conditional on the reference portfolio, we analyze learning externalities to less transparent markets. Specifically, we identify cultural familiarity as a source of learning-based return co-movements.
Does distraction reduce the alcohol-aggression relation? A cognitive and behavioral test of the attention-allocation model.

OBJECTIVE This study provided the first direct test of the cognitive underpinnings of the attention-allocation model and attempted to replicate and extend past behavioral findings for this model as an explanation for alcohol-related aggression. METHOD A diverse community sample (55% African American) of men (N = 159) between 21 and 35 years of age (M = 25.80) were randomly assigned to 1 of 2 beverage conditions (i.e., alcohol, no-alcohol control) and 1 of 2 distraction conditions (i.e., distraction, no-distraction). Following beverage consumption, participants were provoked via reception of electric shocks and a verbal insult from a fictitious male opponent. Participants' attention allocation to aggression words (i.e., aggression bias) and physical aggression were measured using a dot probe task and a shock-based aggression task, respectively. RESULTS Intoxicated men whose attention was distracted displayed significantly lower levels of aggression bias and enacted significantly less physical aggression than intoxicated men whose attention was not distracted. However, aggression bias did not account for the lower levels of alcohol-related aggression in the distraction, relative to the no-distraction, condition. CONCLUSIONS These results replicated and extended past evidence that cognitive distraction is associated with lower levels of alcohol-related aggression in highly provoked males and provide the first known cognitive data to support the attentional processes posited by the attention-allocation model. Discussion focused on how these data inform intervention programming for alcohol-related aggression.
Nasal Bone Fractures In Children And Adolescents. Patient Demographics, Etiology of The Fracture and Evaluation of Plain Film Radiography as a Diagnostic Method in Children's Clinical University Hospital

Nasal bones are the second most common site of fractures in the craniofacial area in pediatric population. Nasal fractures are less common in very young children mostly due to underdeveloped nasal bones and other factors. Nasal bone fractures can be diagnosed clinically. Plain film radiographs are not indicated if an uncomplicated fracture is suspected. They may be difficult to interpret and have low specificity and sensitivity. Aim: To retrospectively collect data of patients admitted to the Children's Clinical University Hospital, Otorhinolaryngology department with the diagnosis " Fracture of nasal bones " S02.2 (ICD-10) from 01.01. 2012 to 31.12. 2014. To obtain descriptive statistics concerning pediatric patients. Also, to evaluate if the plain film x-ray is a necessity when diagnosing nasal bone fractures and its impact on the decision for surgical reduction of the fracture. Results: During the time period of three years given above there were 153 patients admitted to the ENT department with diagnosis S02.2. Among those 120 (78,4%) were male and 33 (21,6%) were female. Most patients, 103, were 13 to 17 years old. The etiology of trauma was obtained from 89 (58,2%) patients' histories. Convincingly the most common cause was sports trauma in 43. Statistical analysis showed no statistically significant connection (p=0,296) between the positive findings of nasal bone fractures and the decision to perform a reduction of the fracture. However, it showed a statistically significant association (p<0,05) between deformity of the nose and the decision to perform the reduction. Conclusions: Based on the descriptive statistics a risk group of nasal bone fracture patients in pediatric population can be outlined – boys who do contact sports in their early teenage years. As to plain film radiography it is safe to conclude that it is unreliable for the evaluation of nasal fractures in children. Furthermore, this study showed, that the decision for the surgical reduction of the fracture can be based on the results of a thorough patient examination and the fact that the patient presents with a visual deformity of the nose.

The study revealed that the perceived risk and the personal characteristics of the entrepreneurs are the major factors that prevent them from venturing into Facebook commerce. This study will help the government to formulate more policies to provide assurance of more security policies that can encourage small and medium enterprises to explore Facebook commerce in the global marketplace.
The Minimally Important Difference for the Health Assessment Questionnaire in Rheumatoid Arthritis Clinical Practice Is Smaller Than in Randomized Controlled Trials

Objective. Patient-reported outcomes are used in clinical practice and trials. We studied a large clinical practice to determine the minimally important difference (MID) estimates for (1) the Health Assessment Questionnaire–Damage Index (HAQ-DI): improvement and worsening using patient global assessment anchor; and (2) pain using a patient-reported pain anchor. Methods. Patients with rheumatoid arthritis (RA; N = 225) had clinic visits at 2 timepoints within 1 year, completed the HAQ-DI and pain visual analog scale (VAS; 0–100 mm), and answered the question, “How would you describe your overall status/overall pain since the last visit? ”, as much worsened, somewhat worsened, the same, somewhat improved, or much improved. If rated as somewhat improved or worsened, they were defined as the minimally changed subgroups. Results. Eighty-three percent were women, mean age 60 years, with disease duration 11.7 ± 10.7 years. The baseline HAQ-DI was 0.97 ± SD 0.76, and at followup 1.0 ± 0.77 (mean change +0.03 ± 0.40). The baseline pain VAS was 42.3 ± 28.8, and at followup 38.5 ± 27.9 (mean change −2.8 ± 25.9). The mean (SD) HAQ-DI change score was −0.09 (0.42) for somewhat improved and 0.15 (0.33) for somewhat worsened. The HAQ-DI change for somewhat/much better was −0.20 ± 0.52, and for somewhat/much worse +0.21 ± 0.33. For pain, somewhat improved changed by −11.9 mm on the VAS, and somewhat worsened by 6.8 mm. Estimates for HAQ-DI and pain were larger than the for no-change group, 0.03 (0.32) and −3.2 (20.9). Conclusion. The MID for HAQ-DI in clinical practice is smaller than it is in trials. This may have implications for observational studies and clinical care.
Anomalous third head of biceps brachii muscle and its variant insertion compresses surrounding neurovascular structure: a rare case report

Biceps brachii (BB) is one of the muscles which are subjected to many variations. Recently, there is a lot of information about variations in origin but also some cases are reported on variations in insertion of BB. Presented herein was a case of BB muscle having both variant origin and insertion in the same muscle. The variant origin of BB was long and large at its third head (10.2 cm width and 4.9 cm breadth) which arises from mid-shaft of the humerus. More significantly, the medial portion of the head covers and conceals the lower portion of median nerve and brachial artery as an arch which continues medially to be inserted to the medial epicondyle of the humerus. We discuss in this report, the possible mechanism for neurovascular compression by this abnormal third head of BB muscle and the variation of BB from its origin and insertion. Understanding these variations is highly significant in surgical procedures around elbow joint and upper arm and it also pave the way for the differential diagnosis in nerve entrapment syndrome.
Economic Consequences of Disaggregate Energy Consumption in West African Countries

Using the data over the period 1971-2010 and employing Dynamic Ordinary Least Squares for Cointegrated Panel Data with homogeneous long-run covariance structure across cross-sectional units, this paper assesses the costs of disaggregate energy consumption on the growth of output and of its components in eight selected West African Countries. The results show that fossil fuel consumption affects industry and agriculture negatively and positively affects per capita output growth, with none of the results statistically significant. There is positive relationship between electricity consumption and industry with statistically significant result. However, there is negative relationship between electricity consumption, agriculture and per capita output growth rate and the results were not statistically significant. Also, there is positive relation between road energy consumption, agriculture and output growth rate with statistically significant results. We find negative relation between diesel consumption, agriculture and output growth rate, but the relation between diesel consumption and industry is positive. However, none of these results is statistically significant. The study concludes that high priority should be placed on constant and stable supply of electricity and road energy.
Developmental Stages in Human Embryos: Revised and New Measurements

The staging of human embryos, as distinct from seriation, depends on a morphological scheme devised by Streeter and completed by O’Rahilly, who proposed the term Carnegie stages. To avoid misconceptions and errors, and to place new findings in perspective, it is necessary to summarize the essentials of the Carnegie system: (1) Twenty-three stages cover the embryonic period, i. e. the first 8 postfertilizational weeks of development. (2) The system is based on internal as well as external features, and the use of only external criteria is subject to serious limitations. For example, precise delineation of stages 19–23 and of the embryonic-fetal transition depends on histological examination. (3) Prenatal measurements are not an integral component of the staging system, and hence a stage should never be assigned merely on the basis of embryonic length. A 20-mm embryo, for example, could belong to any of three stages. Measurements, however, are important for the assessment of age, and very few measurements are available for staged embryos. Presented here and based on accurate staging are the maximum diameter of the chorionic sac, the crown-heel length, the greatest length exclusive of the lower limbs, the biparietal diameter, the head circumference, the length of the hindbrain, the total length of the brain, and the lengths of the limbs as well as of their segments, including the foot length. (4) Prenatal ages are also not an integral part of the staging system and hence a stage should never be assigned merely on the basis of prenatal age. Ages, however, are of clinical importance and their estimate has been rendered more precise by accurate timing of fertilization followed by ultrasonography. Prenatal age is postfertilizational and hence some 2 weeks less than the postmenstrual interval. The term gestational age is ambiguous and should be discarded. Presented here is a new graph showing proposed estimates of age in relation to stages and based on current information.
GODFATHERISM, OWNERSHIP INFLUENCE AND MEDIA TREATMENT OF POLITICAL CONFLICTS IN OYO STATE, NIGERIA

Media coverage of political crises, especially in a terrain fraught with the increasing influence of godfatherism, ownership and political affiliation has a serious consequence on the society. The political feud between Late Chief Lamidi Ariyibi Adedibu and his "political son", Senator Rashidi Adewolu Ladoja in Oyo State, Nigeria (2005-2007), provided a typical example of godfatherism, and media coverage of the conflict typified ownership influence on news media operations. Anchored on the framing theory, this study employed content analysis to examine how The Nigerian Tribune and The Nation newspapers treated the political conflict in terms of the degree of prominence accorded the two principal actors and how ownership factor and political affiliation shaped the contents of the newspapers. Findings show that The Nation, a newspaper believed to be owned by a stalwart of the Action Congress of Nigeria (ACN), was less critical of Senator Rashidi Ladoja and reported more of anti-Adedibu stories. The Nigerian Tribune, on the other hand, reported more of anti-Ladoja stories, and was less critical of Chief Lamidi Adedibu. This paper concludes by urging media actors to free themselves from the web of partisan politics and be more objective in the discharge of their duties as societal watchdogs.
