A probabilistic analysis of the trading the line strategy

We provide analytic models for which the appropriate statistics of the trading the line strategy, N h , can be derived in closed form. In particular, we provide closed-form expressions concerning the average duration of the open position, E(N h ), the variance of the open duration, Var(N h ), the average of the stopped log price, E(S N h ), the variance of the stopped log price, Var(S N h ), the correlation, Corr(N h , S N h ), and the Laplace transform, E(e−s N h ). These results are obtained, in discrete time settings, for binomial and other price scenarios. Furthermore, when analytic results are not possible, such as the case of a normal distribution for log returns, we show by simulation that our general conclusions still hold. Using these statistics we point out some of the subtle features of the trailing stops strategy.
Inelastic models of lithospheric stress-11. Implications for outer-rise seismicity and dynamics

SUMMARY Outer-rise seismicity and dynamics are examined using inelastic models of lithospheric deformation, which allow a more realistic characterization of stress distributions and failure behaviour. We conclude that thrust- and normal-faulting outer-rise earthquakes represent substantially different states of stress within the oceanic lithosphere. Specifically, the normal-faulting events occur in response to downward plate bending, which establishes the 'standard', bending-dominated state of outer-rise stress, and the thrust-faulting events occur in response to an elevated level of in-plane compression, which develops only in response to exceptional circumstances. This interpretation accounts for the observation that normal-faulting outer-rise earthquakes occur more frequently and are more widely distributed than their thrust-faulting counterparts, an observation for which the simple bending model offers no explanation. In addition, attributing both thrust- and normal-faulting outer-rise earthquakes to plate bending implies that both classes of events should occur within relatively close lateral proximity to one another because both are allegedly a manifestation of the same bendingdominated stress distribution, whereas, in reality, this is not observed. We propose that the tendency for thrust-faulting outer-rise earthquakes to exhibit greater source depths than their normal-faulting counterparts (an observation that is frequently cited in support of the bending interpretation of the former) is merely a consequence of the fact that bending-induced tension is confined to the upper lithosphere. Our model predicts that outer-rise in-plane-force variations may promote thrust-faulting outerrise activity prior to an underthrusting interplate subduction earthquake and normalfaulting outer-rise activity following such an earthquake, but that both forms of outerrise activity are unlikely to be associated with the same subduction earthquake. A corollary implication of our model is that subduction earthquakes are likely to be either preceded by or followed by an absence of large outer-rise earthquakes. Levels of in-plane compression necessary to generate thrust-faulting outer-rise earthquakes are attributed to stress concentrations within the subducting plate that are induced by relatively localized resistance to regionally distributed plate-driving forces. Resistance of this nature may result from either the attempted subduction of relatively buoyant (i.e. isostatically compensated) bathymetric features or the existence of strong interplate
Coconut Fiber Strengthen High Performance Concrete: Young’s Modulus, Ultrasonic Pulse Velocity and Ductility Properties

This paper emphasis on experimental investigation to govern the engineering properties such as young’s modulus, pundit ultrasonic pulse velocity (UPV) and ductility of High Performance Concrete (HPC) with grade M60 with addition of coconut fibre (CNF) together with silica fume (SF) and pulverised fuel ash (PFA). For this study, 3 mixes were prepared. First was the CNFRC without any additives, secondly the CNFRC made by 10% replacement of cement weight with PFA and thirdly composition of 10% of cement weight was exchanged with SF. It should be pointed out that for each mix; CNF was included in the mixture (0.5% of the mix volume). The investigational results had shown that the Young’s modulus of CNFRC, CNFR SFC and CNFR PFAC enhanced by about 6%, 3%, and 12% correspondingly. In terms of ductility, when control HPC specimens were subjected to axial compressive strength, slight preliminary cracks shaped on the surface of specimens. Among all HPC specimens tested, CNFR PFAC attained the utmost UPV at 28 day.

Relationships Between Individual and Family Factors and Cognitive Dimensions of Reading Comprehension Among Iranian Students

This study analyzed the relationships between individual and family cognitive factors and attitude towards reading with reading self-concept and outside reading activities and parents’ literacy that are in 4th grade Iranian students. The main of the study is based on interpretations and comprehension of PIRLS 2006. A total of 5411 students (2500 girls and 2911 boys) with average of 10.2 years old participated in PIRLS 2006 test. Reading self-concept and attitude towards reading by the student questionnaire of and outside reading activities and parents’ literacy by the questionnaire of survey of learning and reading comprehension scores were tested. The results of the study showed that all the variables of cognitive comprehension of students are significant (at the level of p<0.01). The reading parents’ literacy was the most determination variance for students’ comprehension and the reading self-concept, attitude towards reading and outside reading activities.
Can Remittances Spur Economic Growth and Development? Evidence from Latin American Countries (LACs)

For the last five decades, there have been heated debates on the sources of economic growth in developing economies. The perceived factors of economic growth have ranged from surplus labor to investment in human and physical capital, transfer of technological change, overseas development assistance, flow of private capital, increasing returns from investment in new ideas and research and development. The impacts of the above listed traditional sources of economic growth have been well documented in literature. Researchers have also considered the importance of institutional factors such as the role of political freedom, political instability, voice and accountability on economic growth and development. Despite the increased size of remittances in the total international capital flows, however, the relationship between remittances and economic growth has not been adequately studied. This study explores the aggregate impact of remittances on the economic growth of 18 Latin American Countries within the conventional neoclassical growth framework using an unbalanced panel data spanning from 1980 to 2005. We find that remittances have a positive and significant effect on the growth of Latin American Countries where the financial systems are less developed by providing an alternative way to finance investment and helping overcome liquidity constraints.
Effect of accessions on the chemical quality of fresh pumpkin

Twenty (20) fresh pumpkin fruits were assessed for dry matter, total soluble solid, total sugar, reducing sugar, titratable acidity, pH, ascorbic acid and sugar-to-acid ratio. Statistically significant (P < 0.01) differences were found for dry matter, total soluble solid, total sugar, reducing sugar, titratable acidity, ascorbic acid, pH and sugar to acid ratio for the 20 fresh pumpkin fruit accessions. Accession 8007 had the highest dry matter, total titratable acidity, total soluble solid and total sugar content. Accession 8007 was also found to have high concentration of ascorbic acid although pumpkin fruit accession 8807 had the highest ascorbic acid. Pumpkin accession 4707 had the highest amount of reducing sugar and titratable acidity while accession 7707 had the highest pH and total soluble solid/ total titratable acid (TSS/TA) ratio. Pumpkin accession 8007 was found to be superior variety with the highest nutritional value while accession 1307 and 3907 were found to be inferior to the accessions evaluated in this study. Key words : Pumpkin, accession, Ethiopia, nutritional value.
Affect and firm performance : The mediating role of entrepreneurial skills

Affect has been described to predict a variety of firm performance indicators but at present, little is known which mechanism(s) underlie this relation. Studies have shown that affect influences entrepreneurial skills, which were also shown to influence some firm performance measures (e.g. Baron, 2008; Sharon, 2003). Yet, it was never empirically tested whether entrepreneurial skills mediate the affect-firm performance relationship. I hypothesize that affect predicts entrepreneurial skills, which in turn predict firm performance and that entrepreneurial skills significantly mediate the relationship between affect and firm performance. In the present study, firm performance is measured through two different indicators, current performance and growth performance. Using a sample of 228 Dutch sole-proprietors, I find support for the mediating role of entrepreneurial skills. However, in contrast to previous studies, I do not find a significant influence of affect on firm performance, indicating that the influence is are rather indirect than direct. Results add to our understanding of how individual traits influence firm performance and imply economic benefits of promoting positive and reducing negative affect.

Context-specificity in facial cues of leadership

Facial cues can have context-contingent effects on leadership judgments, with dominant-looking individuals judged as better leaders in wartime than peacetime contexts and trustworthy-looking individuals judged as better leaders in peacetime than wartime contexts. To further explore this issue participants rated faces for dominance, trustworthiness, attractiveness, effectiveness as leader of a country during wartime or peacetime, and effectiveness as leader of a company manufacturing cars or clothing. Principal component analysis of potential leaders’ characteristics that predicted leadership judgments in prior research produced three components, reflecting general positive regard, dominance, and height, respectively. Perceived dominance and actual height positively predicted leadership judgments in a wartime context but not in a peacetime context. Positive regard positively predicted leadership judgments in a peacetime context, but not in a wartime context. Similar patterns of results were observed for leadership judgments in car manufacturing and clothing-manufacturing contexts. Together, these results present further evidence for context-contingent effects of facial cues on hypothetical leadership judgments.
How is corporate diversification coded into Real Options language ? The interaction between growth options , diversification scope and relatedness

This paper investigates how corporate diversification interacts with a firm’s growth options value. We adopt an options-based perspective, from which diversification is seen as both a materialization of current growth options exercise and a source of future options to expand. We focus on two dimensions of this strategy: degree of diversification and relatedness between segments. We posit that at low levels of diversification, the option exercising effect prevails, whereas the option creation effect dominates at higher diversification levels. Relatedness sparks interaction effects among growth options, which may make the value of the portfolio non-additive. This effect of relatedness may be moderated by diversification scope, which sets out the relative importance of synergies versus coordination costs. Using a panel sample of U.S. firms from 1998-2010 and accounting for endogeneity, we confirm a U-relationship between diversification and growth options. Results also reveal an inverse U-linkage between relatedness and the firm’s growth options value, which is less pronounced in high diversifiers than in low ones. This study extends the applicability of the real options approach to strategy, and suggests the relevance of a multidimensional and contingent view in the diversification debate.

Both adult and larva of predator voraciously consumed on an average, 60.56 and 141.01 aphids per day, respectively and the total developmental period was noted to be 18.75 days.
Effects of Macroeconomic Variables on Foreign Direct Investment in a Liberalized Economy: The Case of Nigeria

The study investigated the impact of some selected macroeconomic variables on the attraction of foreign direct investment (FDI) in Nigeria between 1975 and 2009. Augmented Dickey-Fuller test was used to examine the time series property of the data and Johansen co-integration test was employed to ascertain the long-run relationship between the dependent variable (FDI) and the independent macroeconomic variables. Ordinary least technique also was employed in the study. Error correction coefficient was high, rightly signed and significant which reveals a long run relationship between the selected macroeconomic variables and FDI for the period of study. The explanatory variables included in the model showed statistical significant impact on FDI. The overall regression was significant as denoted by the probability of the F-statistic at 5% significant level. On this note, among the recommendations made include: the Nigerian government should promote non-oil exports and discourage over dependence on imports of goods and raw materials; diversification of the economy should be paramount in the minds of the resource managers of our economy and it is imperative that the country has to promote private sector led growth and the creation of enabling environment, especially infrastructure.
The Effect of Fe Additive on Plastic Deformation for Crush-Boxes with Closed-Cell Metal Foams, Part I: Al-Composite Foam Compression Response S.M.H.Mirbagheri

In this study, the effect of Fe–intermetallic compounds on plastic deformation of closed-cell composite Aluminum Foam as the filler of thin-walled tubes is investigated. Composite foams of AlSi7SiC3 and AlSi7SiC3-(Fe) as a closed cell were synthesized through powder metallurgy foaming method. Macro and Micro structures of the produced foams revealed a non-homogenous cell which is dependent on Fe-rich intermetallic compounds. The cellular structure of AlSi7SiC3 foam shows a non-uniform and small size of bubbles with a few central big voids in comparison with the AlSi7SiC3-(Fe) foams. The analysis of EDAX (Energy Dispersive Analysis of X-rays) indicate that there are (α+β)-Feintermetallic compound within foams with Fe < 2 wt. %, and (α+δ)-Fe-intermetallic compound for the foams with Fe > 2 wt. %, in which their presence depend on the cooling rate during the solidification of liquid foams. The stress-strain curve of the AlSi7SiC3 foam shows a smooth plastic deformation behavior in the plastic region, throughout the compression tests. However, by increasing the weight percent of Fe from 1 up to 3%, the curve shows some variation at the slope of curves within the plastic zone. The results obtained indicated that all of the compression response is due to the micro-porosity in plateau region and the presence of the Fe-Al-Si-intermetallic within the cell wall revealed that both of them have the role of a stress concentration point during the compressive loading.
Sero-conversion of Avian Influenza Virus Subtype H9N2 in Non-Vaccinated Commercial Poultry Flocks

Sero-conversion of pathogenic subtypes (H5, H7 and H9) of Avian Influenza Virus types was studied in commercial poultry farms in the Province of Punjab, Pakistan during the years 2015-16. Out of 6731 morbid tissues, only 11 samples (4 from broiler, 4 from broiler breeder and 3 from commercial layers farms) were found positive for Avian Influenza Virus (AIV) H9N2 type. Only one isolate was found positive for H9N2 subtype from 17994 tracheal swab samples. All the 37163 cloacal swab samples were found negative. The sero-analysis of 133438 blood sera samples showed sero-conversion in 66219 samples (49.64%) against H9 virus in the non-vaccinated poultry flocks, when tested with Heamagglutination Inhibition test (HI). Highest sero-conversion was recorded in broiler breeder (49.20%) followed by broilers (47.47%), layer (46.25%) and Native/Desi birds (45.59%). Highest HI titres were recorded in the flocks from Muzaffargarh, Rawalpindi, Toba Tek Singh, Sargodha, Gujrat, Faisalabad, Sheikhupura, Jhelum and Pakpattan while Bahawalpur, Gujranwala, Lahore, Jhang, Okara and Multan had relatively lower level of HI antibody titres. In conclusion only one type of AIV subtype H9N2 is prevailing in the province of the Punjab, Pakistan.
Influence of a seed magnetic field on the imploding cylindrical Richtmyer-Meshkov instability in magnetohydrodynamics

We investigate the behaviour of the ideal magnetohydrodynamic (MHD) Richtmyer-Meshkov instability (RMI) in twodimensional implosions under the influence of uniform- and saddle-topology seed magnetic fields. The RMI is a hydrodynamic instability that, along with the Rayleigh-Taylor instability, greatly limits the operating parameters of inertial confinement fusion (ICF), a technology that has recently seen much interest for its potential for energy production. The instability arises when a perturbed density interface is impulsively accelerated, for example by a shock wave, causing the perturbations on the interface to grow as a result of baroclinic vorticity generation. Here we present case studies of the MHD RMI in converging two-dimensional geometry, in the presence of uniform- and saddle-topology seed fields. We examine the shock refraction process, identifying the waves that result from it, and determine the growth rate of the RMI, comparing it to its behaviour in the converging hydrodynamic (no-field) case. We drive the incident shocks with a Riemann problem, and examine the RMI under various perturbation wavenumbers and seed field strengths. The shock refraction processes produce a collection of fast and subfast MHD shock waves which carry vorticity along and away from the interface perturbations, depending on the local field orientation to the interface, supressing the instability but leading to slightly irregular perturbation shapes. These results encourage further research on the MHD RMI in converging flows, with a strong potential for application to ICF experiments.
Effect of repeated laparoscopic ovum pick-up on yield and quality of oocytes in goats.

Laparoscopic ovum pick-up (LOPU) is a less invasive surgical technique for oocyte recovery from antral follicles seen as ‘pimple-like’ protrusion on the ovarian surface. LOPU can be repeated several times without ovarian damage or reducing the doe’s fertility. This study investigated the effect of LOPU cycles on yield and quality of oocytes in goats. Three repeated cycles (oocyte retrieval 1 (OR1), oocyte retrieval 2 (OR2) and oocyte retrieval 3 (OR3)) of LOPU procedure were performed on 16 donor Boer crossbred does. The oocytes obtained were classified based on cumulus oocytes complexes (COC) layer criterion into 5 grades: grades A, B, C, D and E. OR1 gave a higher number of quality oocytes (P 0.05) among the OR cycles. The number of grade A oocytes obtained in OR1 and OR2 was significantly higher (P 0.05) than for grades A and B oocytes with mean oocyte recovery rate of 153 versus 106 and 91%, respectively. In conclusion, LOPU is a reliable procedure to provide consistently high quality oocytes of grades A, B and C and its usage can be repeated on the same donor doe for up to 3 times. However, the number of oocytes is reduced following each oocyte retrieval cycle.
