The Effect of Heuristics on Stock Buying Decisions of Individual Investors: Evidence from the Nigerian stock exchange

Empirical evidence from developed countries have established that heuristics biases do have significant effect on individuals’ investment decisions in stock market, but there is very limited number of studies conducted in less developed countries especially in Sub- Saharan Africa and Nigeria in particular. In view of this, this paper attempts to bridge the gap by examining the effect of heuristics on individuals’ investors stock buying decisions based on the Nigerian stock market context using a survey strategy. A sample of 400 questionnaires were administered to individual investors, the data collected were analysed with multiple-linear regression using SPSS Software. The findings revealed that heuristics biases have significant effect on individual investors stock buying decisions with R² = . 563, F(5, 211) = 79.31, p < . 001. The study further revealed that gambler’s fallacy, availability bias and overconfidence had the highest effect, indicating that investors exhibiting these heuristics may tend to used locally available information, based their selling decisions on purchase price, and may overestimate their ability to process information while making stock buying decisions. The study, proposed that investors need to be aware of these biases and its implication on their subsequent investment performance. The security market operators need to create more awareness about these biases, so as to enable individual investors make an informed decision about the stock they buy.
Alternative Splicing of LYT1 Transcripts in Trypanosoma cruzi

ABSTRACT As a result of alternative trans splicing, three distinct LYT1 mRNAs are produced in Trypanosoma cruzi, two encoding the full-length LYT1 protein and the third encoding a truncated LYT1 protein lacking a possible signal sequence. Analysis of the three mRNAs in different developmental forms of the parasite revealed that the alternative processing events were regulated differently during the parasite life cycle.
Iran Economic Monitor : Weathering Economic Challenges

Iranʼs GDP growth in 2017/18 eased considerably as the effect of large surge in oil revenues in the previous year dissipated. After undergoing an oil-based bounce in the economy in 2016/17, the economy registered a 3.8 percent growth in 2017/18 with the overwhelming majority of growth coming from the non-oil sectors. More than half of the growth can be attributed to services which grew by 4.4 percent. Oil, agriculture and services sectors are now back above the levels of activity they were prior to sanctions in 2012. But there was not a strong bounce back in the past two years for key sectors such as construction and trade, restaurant and hotel services following the stagnation in growth during the period of sanctions. The oil and gas sector witnessed a growth of 0.9 percent. Limited by the (Organization of the Petroleum Exporting Countries) OPEC quota for the agreed period, increasing production capacity or maintaining current production levels in the coming years would require a substantial increase in investments in the sector.
Negative group delay circuit with independently tunable center frequency and group delay

In this paper, a design of negative group delay circuit (NGDC) with independently tunable center frequency and group delay (GD) is presented. Since the proposed structure consists of a parallel RLC resonance circuit, it is possible to obtain a variable negative GD by using a variable resistor and an adjustment of center frequency of GD is possible due to a variable inductor. To get the pure variable resistor, the transmission line (TL) terminated with the PIN diode is used. Similarly, the variable inductor is realized by TL terminated with the varactor diode. To show the effectiveness of the proposed NGDC, it is designed at 2.14 GHz of WCDMA downlink band. The measured negative GD time is -2 ~ -20ns, and are able to change the center frequencies of negative GD in the range of 2.04 ~ 2.24 GHz.
Electricity market reform and potential tacit Collusion – An event study

Overview In Norway, the Energy Act came into force in 1991, and laid the foundation for one of the first market based electricity systems in the world. Numerous studies have studied the performance of the liberalized electricity market in Norway and conclude that the overall performance of the market is fairly good (Amundsen & Bergman, 2003; Amundsen, Bergman & Von der Fehr, 2006; Bye & Hope, 2005; Littlechild, 2006). However, there are market characteristics that represent strong incentives for tacit price collusion in the Norwegian electricity retail market.
Visual Attention Guided Deep Imitation Learning

When an intelligent agent learns to imitate human visuomotor behaviors, it may benefit from knowing where the human is allocating visual attention, which can be inferred from their gaze. A wealth of information regarding intelligent decision making is conveyed by human gaze allocation; hence, exploiting such information has the potential to improve the agent’s performance. With this motivation, we collect high-quality human action and gaze data while playing Atari games. We first train a deep neural network that can predict human gaze positions and visual attention with high accuracy (the gaze network) and then train another deep neural network to predict human actions (the policy network). Including the gaze predictions from the gaze network in the policy network significantly improves the action prediction accuracy. We conclude that it is feasible to learn human attention in the given visuomotor tasks, and that combining the learned attention model with imitation learning yields promising results.
On the Dual-Band DRA-Slot Hybrid Antenna

A dielectric resonator antenna (DRA) is placed on top of a slotted cavity to form a hybrid dual-band antenna. The zonal slot cut onto the cavity is fed by an embedded L-probe, whereas the DRA is fed by a coupling rectangular slot cut on the top face of the cavity. It is found that the resonance frequencies of the zonal slot and DRA are primarily dependent on the zonal slot and the DRA, respectively, which greatly facilitates the dual-band design. To demonstrate the idea, the proposed hybrid dual-band antenna is designed for IEEE802.11a/b WLAN applications. The reflection coefficient, radiation pattern, and gain of the dual-band antenna are studied, and the simulation and measurement are in reasonable agreement. A parametric study of the proposed configuration was carried out to characterize the antenna.
An Investigation of Buyers’ Forecast Sharing and Ordering Behavior in a Two-Stage Supply Chain

Profitably balancing demand and supply is a continuous challenge for companies under changing market conditions, and the potential benefit of collaboration between supply chain partners cannot be overlooked by any firm who strives to succeed. One of the key elements to successful collaboration is sharing of forecast information between supply chain partners. However, when supply shortage is expected, buyers may inflate order quantities and/or order forecasts to secure sufficient supply. An important question that arises is how the supplier should allocate inventory to customers when shortage exists. Literature shows that certain allocation policies can reduce buyers’ order inflation behavior. However, this has not yet been empirically shown for order forecast inflation behavior, nor incorporating the behavioral aspects of decision makers. In this dissertation, through behavioral experiments using a supply chain simulation game, we investigate the impact of different capacity allocation mechanisms and information disclosures of a supplier on buyers’ forecast sharing and ordering behavior. We first investigate the buyers’ order forecast sharing behavior in a single-suppliertwo-buyer supply chain. Our behavioral study shows that forecast-accuracy based allocation, where the supplier allocates more capacity to the buyer with better forecast accuracy, can significantly improve order forecast accuracy relative to uniform allocation, where the supplier equally allocates capacity to the buyers. Under both policies, particularly uniform allocation, the order forecast accuracy is improved with the supplier’s information disclosure on the policy. Next, we focus on buyers’ ordering behavior, and formulate a single-supplier-single-buyer base-stock inventory
Men of Honor: Military CEOS and Directors in Korea

In this paper, we examine whether the presence of ex-military board directors affects firms’ financial policies and ethical behavior in Korea, a country where the military has a unique historical role in society. Despite prolonged exposure to military rule during their formative years, firms with ex-military-officer CEOs and inside directors are substantially less likely to commit corporate fraud. Moreover, the positive association between Chaebol business groups and fraud is significantly weakened in the presence of ex-military directors. These managers and insiders also adopt more conservative managerial policies in normal times but take more risks during crisis periods. However, when these directors are appointed primarily for external networking purposes, their presence has little effect on a firm’s corporate policies or ethical behavior. Thus, a director with exposure to military values does appear to enhance corporate ethics, but only when he holds an appropriate position to do so.
Ergodic Secrecy Rate of Randomly Deployed Cellular Networks Enhanced by Artificial Noise

As the future cellular networks tend to be randomly deployed and equipped with more antennas, we study the enhanced secrecy rate of multiple- input multiple-output (MIMO) systems with a stochastic geometry approach. To avoid intractable computational complexity and to have a deep insight into the security performance of such networks, we derive a closed-form lower bound on the ergodic secrecy rate, based on which the optimal power allocation parameter is derived. Analytic and Monte-Carlo simulation results show that the lower bound is quite tight. The density of base stations (BSs) and number of antennas both greatly infects the optimal power allocation parameter, e.g., positive secrecy rate may not achieved when the BSs density is small, otherwise the optimal power allocation will increase with the increase of the BSs density.
Importance-performance Analysis to Identify Effective Learning Approaches for Sustainability in an Indian Business School

Sustainability and sustainable development have become a crucial keyword in today’s environment. It is now being felt that incorporation of sustainable practices should not be followed only by different sectors (public or private) but these concepts should also be taught at business schools to embed the concepts of sustainable practices right from the very beginning. There are 37 learning approaches identified on the basis of Principles for Responsible Management Education (PRME), which forms the core of the work presented in this study. To implement the proposed analysis, responses were collected from the students of a top public management institute of India on the basis of importance and performance parameters of the learning approaches for sustainability. The responses were than analysed through importance-performance analysis (IPA). It was observed that most effective learning approaches for learning the concepts of sustainability issues include case studies, lectures by experts, internships on sustainability etc. Students also perceived the significance of sustainability in business management and also showed preference to work with those companies, which actually holds sustainability as a core value.
A Robust Fuzzy Clustering Approach And Its Application To Principal Component Analysis

Abstract A robust fuzzy clustering approach is proposed to simplify the task of principal component analysis (PCA) by reducing the data complexity of an image. This approach performs well on function curves and character images that not only have loops, shazp corners and intersections but also include data with noise and outliers. The proposed approach is composed of two phases: fustly, input data are clustered using the proposed distance analysis to get good and reasonable number of clusters; secondly, the input data are further re-clustered by the proposed robust fuzzy c-means (RFCM) to mitigate the influence of noise and outlier data so that a good result of principal components can be found. Experimental results have shown the approach works well on PCA for both curves and images despite their input data sets include loops, corners, intersections, noise and outliers.
Dynamic Characteristics of Linear and Nonlinear Wideband Photonic Crystal Filters

The heart of such all-optical circuit is nonlinear PhC which may provide the basis for logic, memory cells, switching, local routing, power limiters, isolators, etc. Therefore, it is of crucial importance to understand the processes taking place in such components and optimize their characteristics. One of the most important points of view to the PhCs is their interaction with short and ultra-short pulses which may limit the productivity of an optical circuit. Recently, there have been proposed a great number of PhC components bases on different operating principles. However, being resonant-transmitting structures, PhCs themselves reduce the possibility to work with ultra-short pulses.
Prospects of non-ferrous metallurgy enterprises participation in industrial clusters

Formation of industrial clusters network facilitates the competitive potential of territories. Such a development paradigm is defined as the main paradigm among the majority of world countries. This article studies the implementation of clusters in industry, in particular in EU, the impact of clusters on the competitiveness and localisation of areas, as well as the promotion of growth and scientific and industrial potential of the country as a whole. The article describes the existing prerequisites for the creation of clusters with the participation of non-ferrous metallurgy enterprises. It is shown that currently clustering processes are not being implemented actively enough in the relevant industries, which does not allow us to fully realise scientific and industrial potential of enterprises in the areas of their cluster location. The analysis of existing methods of industrial clustering has shown the presence of the identification stage with evaluating integration potential of possible participants based on the calculation of specific quantitative indicators for the localisation of clusters the so called cluster identification procedure. The results of the analysis also make it possible to justify the expediency of choosing the methodology proposed by the National Research University «Higher School of Economics» and the North-West Foundation as a procedure used to identify industrial clusters in non-ferrous metallurgy, which provides the most complete reflection of the functional areas of industrial clusters. The author proposes to apply the specified procedure when calculating concentration indicators such as the personnel potential, high-performance workplaces, innovations which allow estimating the degree of participants’ interaction potential in non-ferrous metallurgy, which will increase the number of high-performance workplaces, labour productivity and commercialise scientific and technical developments. The procedure of identification of industrial clusters in non-ferrous metallurgy, which was supplemented by the author, was used to analyse two already formed clusters of non-ferrous metallurgy enterprises in Chelyabinsk region (implementation of scientific and production processes associated with the extraction of copper ore, production of copper and copper products) and Krasnoyarsk region (aluminium), as well as the cluster already functioning in Sverdlovsk region, associated with titanium products. The results of the research makes it possible to draw a conclusion about the expediency of spreading the above-mentioned «titanium», «copper» and «aluminium» clustering practices in the territorial integration processes in the Russian non-ferrous metallurgy, taking into account the need to enhance innovation.
Effect of Stratification on Surface Properties of Corneal Epithelial Cells.

PURPOSE The purpose of this study was to determine the influence of mucin expression in an immortalized human corneal epithelial cell line (hTCEpi) on the surface properties of cells, such as wettability, contact angle, and surface heterogeneity. METHODS hTCEpi cells were cultured to confluence in serum-free medium. The medium was then replaced by stratification medium to induce mucin biosynthesis. The mucin expression profile was analyzed using quantitative PCR and Western blotting. Contact angles were measured using a two-immiscible liquid method, and contact angle hysteresis was evaluated by tilting the apparatus and recording advancing and receding contact angles. The spatial distribution of mucins was evaluated with fluorescently labeled lectin. RESULTS hTCEpi cells expressed the three main ocular mucins (MUC1, MUC4, and MUC16) with a maximum between days 1 and 3 of the stratification process. Upon stratification, cells caused a very significant increase in contact angle hysteresis, suggesting the development of spatially discrete and heterogeneously distributed surface features, defined by topography and/or chemical functionality. Although atomic force microscopy measurements showed no formation of appreciable topographic features on the surface of the cells, we observed a significant increase in surface chemical heterogeneity. CONCLUSIONS The surface chemical heterogeneity of the corneal epithelium may influence the dynamic behavior of tear film by "pinning" the contact line between the cellular surface and aqueous tear film. Engineering the surface properties of corneal epithelium could potentially lead to novel treatments in dry eye disease.
A Multiobjective Heuristic for Reconfiguration of the Electrical Radial Network

This paper proposes a new reconfiguration heuristic in order to reduce the total power loss and the maximum current of electrical radial networks. It is based on the branch-and-bound strategy, which is an implicit enumeration method that uses a tree structure and bounds to organize the searching process. The search tree in this paper is constructed by subdividing the feasible set using the branch-exchange technique in the networks. The constraints and the Pareto dominance are responsible for pruning the search tree. The heuristic also returns a feasible switching plan for each solution. The algorithm was successfully applied to medium- and large-scale problems.
Ca2+ Controls Functional Expression of the Cardiac K+ Transient Outward Current via the Calcineurin Pathway*

The transient outward K+ current (Ito) modulates transmembrane Ca2+ influx into cardiomyocytes, which, in turn, might act on Ito. Here, we investigated whether Ca2+ modifies functional expression of Ito. Whole-cell Ito were recorded using the patch clamp technique in single right ventricular myocytes isolated from adult rats and incubated for 24 h at 37 °C in a serum-free medium containing various Ca2+ concentrations ([Ca2+]o). Increasing the [Ca2+]o from 0.5 to 1.0 and 2.5 mm produced a gradual decrease in Ito density without change in current kinetics. Quantitativereverse transcriptase-PCR showed that a decrease of the Kv4.2 mRNA could account for this decrease. In the acetoxymethyl ester form of 1,2-bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid (BAPTA-AM)-loaded myocytes (a permeant Ca2+ chelator), Ito density increased significantly when cells were exposed for 24 h to either 1 or 2.5 mm [Ca2+]o. Moreover, 24-h exposure to the Ca2+ channel agonist, Bay K8644, in 1 mm [Ca2+]o induced a decrease in Ito density, whereas the Ca2+ channel antagonist, nifedipine, blunted Ito decrease in 2.5 mm [Ca2+]o. The decrease of Ito in 2.5 mm [Ca2+]o was also prevented by co-incubation with either the calmodulin inhibitor W7 or the calcineurin inhibitors FK506 or cyclosporin A. Furthermore, in myocytes incubated for 24 h with 2.5 mm [Ca2+]o, calcineurin activity was significantly increased compared with 1 mm [Ca2+]o. Our data suggest that modulation of [Ca2+]i via L-type Ca2+ channels, which appears to involve the Ca2+/calmodulin-regulated protein phosphatase calcineurin, down-regulates the functional expression of Ito. This effect might be involved in many physiological and pathological modulations of Ito channel expression in cardiac cells, as well other cell types.

Noninfectious Lung Pathology in Patients With Crohn's Disease

Lung involvement in Crohn's disease is not well characterized. We reviewed our experience with 11 lung biopsies (seven wedge and four transbronchial) from patients with Crohn's disease to study this association further. Negative cultures, special stains for organisms Gomori-methenamine-silver [GMS], acid fast), and polymerase chain reaction for Mycobacteria tuberculosis (four cases) were required for inclusion. The group included five women and six men with a mean age of 47 years (range 13–84 years). A diagnosis of Crohn's disease preceded the lung disease in nine patients. In two patients the diagnosis of Crohn's disease followed the diagnosis of their pulmonary disease 1 and 15 months later. Radiologically, eight patients had diffuse infiltrates, two had bilateral nodular infiltrates, and one had a mass. Chronic bronchiolitis with nonnecrotizing granulomatous inflammation was present in four patients, one of whom was taking mesalamine. Two patients had an acute bronchiolitis associated with a neutrophil-rich bronchopneumonia with suppuration and vague granulomatous features. One patient on mesalamine had cellular interstitial pneumonia with rare giant cells. Four patients demonstrated organizing pneumonia with focal granulomatous features, two of whom were taking mesalamine, and one of these two responded to infliximab (anti-tumor necrosis factor) monoclonal antibody therapy. Noninfectious pulmonary disease in patients with Crohn's disease has variable histologic appearances, including granulomatous inflammation and airway-centered disease resembling that seen in patients with ulcerative colitis. Drugs may contribute to pulmonary disease in some patients.
