Cheap IPO: Does it matter?

ABSTRACT:It can be argued that a cheaply priced IPO would attract more potential buyers, especially small or retail investors as they are commonly known in Malaysia, which could result in more speculative trading activities due to its “cheap” perception. A fixed-price IPO serves a unique situation in which the price of an IPO is fixed prior to its offering to potential buyers, and it gives the opportunity to test whether or not a cheaply priced IPO can attract more potential buyers which can result in more speculative trading activities, hence higher initial return and price spread. This study examines a sample of 104 Malaysian fixed-price IPOs from January 2009 to December 2014, where I test the relationship between cheaply priced IPOs and their initial returns and also their price spreads during the first day of trading. I hypothesize that a cheaply priced IPO will attract more potential investors (especially the small or retail investors) that will result in a more speculative trading activity that will later push the IPO price higher in the secondary market. A speculative trading activity will also result in a higher price spread, which refers to the difference between the highest and the lowest price. The same situation occurs with regard to trading board, where investors (especially retail investors) are usually more attracted to cheaply priced IPOs, which are associated with IPOs listed on the ACE Market of Bursa Malaysia which caters for small, young and technology companies. As noted by Lowry et al. (2010), IPOs of small, young and technology firms are more difficult to value due to higher information asymmetry between the issuer and the investors, and thus we would expect higher price spread in these IPOs. In general, the results show that IPOs with low offer price and IPOs listed on the ACE Market have higher initial returns and higher price spreads compared to IPOs with high offer price and IPOs listed on the Main Market. The result of this study implies that investors can benefit significantly from investing in IPOs with low offer price. Investors can also benefit from investing in IPOs listed on the ACE Market, which is associated with low-priced IPOs. The implication to the regulatory bodies of Bursa Malaysia is that they should pay closer attention to IPOs with low offer price, and IPOs listed on the ACE Market because these IPOs are subject to speculative trading activities.
The Presynaptic F-box Protein FSN-1 Regulates Synapse Development via Retrograde Insulin Signaling in Caenorhabditis elegans

Synaptogenesis entails the development and establishment of functional synapses, which form the fundamental unit of communication in the nervous system. Initially identified in Caenorhabditis elegans (C. elegans), the FSN-1, F-box protein family has emerged as evolutionarily conserved binding partners of PHR family proteins, which regulate synaptogenesis. Previously, we have shown that FSN-1 and RPM-1 form a SCF ubiquitin ligase complex that negatively regulates synapse growth by downregulating presynaptic targets, like the MAP kinase pathway. For my master’s thesis, I used a combination of both candidate and forward genetic approaches to identify additional components of signaling pathways that are regulated by FSN-1 during synaptogenesis. Our studies are among the first to suggest diverging roles for these partners and provide the first evidence for a mechanism through which the F-box protein regulates synaptogenesis via retrograde insulin/IGF/FOXO signaling and glucosaminidase/OGlcNAc modifications.
IMPACT OF FOOD SUPPLY FREQUENCY AND THE NUMBER OF SHELTERS ON THE GROWTH AND SURVIVAL OF JUVENILE NARROW-CLAWED CRAYFISH (ASTACUS LEPTODACTYLUS ESCH.)

The aim of the research was to study the impact food supply frequency and the number of shelters has on the growth and survival of juvenile narrow-clawed crayfish, Astacus leptodactylus Esch. , fed formulated feed and to determine the dependence of total body length (LT) on the carapace length (LC). In the first experiment, four food supply frequencies were tested for 28 days at a crayfish stocking density of 300 indiv. m -2 . Feed was delivered at intervals of 12 h (08:00 and 20:00), 24 h (20:00), 48 h (20:00) and 96 h (20:00). In the second experiment four different numbers of shelters in the tanks were tested for 30 days at a crayfish stocking density of 1500 indiv. m -2 (0, 60, 150, and 300 shelters m -2 ). Feeding frequency had a significant impact on crayfish body weight, specific growth rate (SGR), and relative growth rate (RGR) (P 0.05). The number of shelters had a highly significant impact on survival and stock biomass (P 0.05). The mean value of the proportion between total body length (LT) and the carapace length (LC) was 1.82 (variation coefficient V = 4.56%). There was a highly significant linear dependence among the morphometric indicators mentioned previously (P < 0.001, r = 0.9209), which was described by the following equation: LT = 1.6009 LC + 1.8662.
Explaining shifts in the unemployment rate with productivity slowdowns and accelerations: a co-breaking approach

We investigate the controversial issue whether unemployment is related to productivity growth in the long run, using U.S. data in a framework of infrequent mean shifts. Tests find (endogenously dated) shifts around 1974, 1986, and 1996, system techniques indicate that the shifts are common features, and the implied long-run link between the two variables is negative. Therefore the secular decline of unemployment since the mid 1990s indeed stemmed from higher average productivity growth. The initial and final regimes are essentially equal, thus supporting theories that explain the productivity slowdown by a slow adoption process of IT with associated learning costs.
EFFECT OF THERMAL RESIDUAL STRESSES ON BUCKLING AND POST-BUCKLING PROPERTIES OF LAMINATED COMPOSITES PERIMETRALLY REINFORCED

Several mechanical properties can be affected by the occurrence of residual stresses due to curing, and their effects are more pronounced in laminated composites. The effect of the thermal residual stresses on the buckling and post-buckling properties of perimetrally reinforced laminated composites is experimentally characterized. Carbon/epoxy laminates were prepared using two different techniques. One group of laminates was prepared by co-curing the reinforcement at 177 °C. The second group of laminates was prepared by secondary bonding of the reinforcement to the laminate at room temperature (22°C). Topogrammetry equipment was utilized in order to determine the buckling and post-buckling properties of these two groups of laminates. A numerical model was achieved using commercial software for comparison with the experimental results. Suitable accuracy was observed when comparing experimental and numerical results. The co-cured laminates developed considerably higher critical load for buckling values than those obtained for laminates produced with secondary bonding at room temperature. The experimental and numerical results of this study demonstrate the importance of curing-induced thermal residual stresses on the mechanical behavior of laminate composites.
A comparative study between modified Patwardhan technique and Foetal Pillow during caesarean section in full dilatation in cases of deeply engaged foetal head

Objective: To evaluate whether use of the Foetal Pillow (Safe Obstetric Systems, Shenfield, UK) reduces maternal and foetal morbidity in cesarean delivery at full cervical dilatation as compared to Modified Patwardhan technique. Methods: A comparative prospective study was conducted in a tertiary teaching hospital, West Bengal between May 2016 to April 2017. A total of fifty women undergoing caesarean delivery at full dilatation (CSFD) were randomised into two groups i.e. Foetal Pillow (FP) and Modified Patwardhan (MP) group. Outcomes such as extension of uterine incision, operating time, uterine incision to delivery time and blood loss were measured. Results: In FP group, only two (8%) had extension of uterine incision as compared to six patients (24%) in MP group, which was statistically significant (p 0.001). Operating time and incision-to-delivery interval was significantly shorter in FP group than MP group (p 0.02 & p 0.04 respectively). Blood loss was also significantly more in FP group than MP group (p 0.02). Conclusion: Foetal Pillow is a quite safe obstetric device for delivery of deeply impacted foetal head during CSFD and provides better outcome compared to Modified Patwardhan technique.
On weakly Ricci symmetric spacetime manifolds

The object of the present paper is to study weakly Ricci symmetric spacetime manifolds. Among others it is proved that if in a weakly Ricci symmetric spacetime of non–zero constant scalar curvature the matter distribution is perfect fluid, then the acceleration vector and the expansion scalar are zero and such a spacetime can not admit heat flux. Finally a study of conformally flat perfect fluid weakly Ricci symmetric spacetime manifold is made.
On the Interaction between the Crude Oil Market and the Macroeconomic Activity: How do the 2000s differ from the 70s?

In this paper, the Cheung-Ng procedure and the rolling correlation method are used to examine how the connection between the crude oil market and the macroeconomic fundamentals of the 2000s differs from the 70s. Our findings show that the economic meltdown (e.g. 2007-08) becomes positively correlated with oil price changes. Indeed, from the 90s the role of oil supply shocks is attenuated compared with the role of aggregate demand to drive the oil price volatility. Hence, the US economic recession leads to rising oil price volatility in the long-term. Therefore, the earlier macroeconomic dynamics permit better forecast of oil market volatility. Inversely, during the 2000s, the macroeconomic variables are found to be strongly and positively influenced by the crude oil price changes in the short-run. Interestingly, the connection of oil prices with the inflation is not really weakened in the 2000s compared with the 1970s in the US.

STUDY OF ORGANIZATIONAL COMMITMENT IN THE CONTEXT OF LEADERSHIP STYLES AND REASONS OF EMPLOYEE SILENCE

The aim of this study is to determine the connections between leadership styles, the reasons of employee silence and organizational commitment. Besides, another goal of this research is to obtain the reasons of the effects of employee silence on relationship between leadership styles and organizational commitment. For this purpose, scales were applied by searching literature related to 758 people. The survey consists of various firms operating in manufacturing and service industry, and data have been analyzed through the SPSS 15 statistical packet program. Established data analyzed with factor analysis, correlation, regression and cronbach alpha methods. Hypotheses concerning the relationship between leadership styles and organizational commitment between the reasons of employee silence and organizational commitment and lastly, reasons of the role of employee silence as a mediator variable between organizational commitment and leadership styles were tested and the relation has been considered as significant. Established diagnosis discussed in the context of relevant literature.
The impact of innovation on jobs, skills and wages

Unemployment, skill polarisation and growing wage inequality are major problems in advanced countries. Technological change in particular the emergence of Information and Communication Technologies (ICTs) has often been called into question as a factor in such labour market developments. This article investigates the impact innovation has on jobs, skills and wages, discussing the concepts for analysis, reviewing the evidence of major studies and providing recent empirical evidence for European countries.
SENSITIVITY EVALUATION OF FIELD SHEAR TEST USING IMPROVED PROTOCOL AND INDIRECT TENSION STRENGTH TEST

There were two primary objectives for the research documented in this short report. One was to evaluate the sensitivity of complex modulus measurements made using the recently improved field shear test (FST), following a new and potentially more effective testing protocol. The other objective was to evaluate the sensitivity of the indirect tension (IDT) strength test, performed at high temperatures in order to evaluate mixture cohesion and rut resistance. Both of these tests are quick and simple--especially the IDT strength test--and are thus good candidates for use as field tests for quality control of asphalt concrete mixtures. The test program used to evaluate the sensitivity of both the FST (new protocol) and IDT strength test was straight forward, and followed in all important aspects the same sensitivity test plan used during the initial evaluation of the FST performed as part of NCHRP Project 9-18. In fact, the same set of specimens was used, though their modulus was somewhat higher due to gradual hardening of the mixtures over time. Four different aggregates were used in the test program, and the composition of each of the resulting four primary mixtures was varied in a consistent way, with changes in coarse aggregate, mineral filler, and asphalt binder content. Four replicate specimens were tested for each mixture variation, ensuring adequate degrees of freedom for statistical analyses. To date, only one FST prototype exists, so the results of this study should be considered preliminary. Additional evaluations of the FST under field conditions are needed, preferably using two or three devices and a number of different operators.
In vivo grafting and in vitro micrografting of Acacia mangium: impact of ortet age.

The possibilities of vegetatively propagating juvenile - 6-month-old and mature - 3 to 5 year-old - #Acacia mangium# ortets by grafting were investigated using in vivo and in vitro techniques. The average success rates obtained for in vivo topcleft grafting were 49% for scions coming from juvenile plant material and 0% when collected from mature ortets. In vitro micrografted apices gave rise to 52% and 46% of successfully established micrografts for the juvenile and the mature plant material respectively. No significant difference between juvenile and mature origins in terms of grafting success was observed for in vitro micrografting of shoot apices. However, the ones coming from the juvenile ortets elongated more readily than those from the mature origin which were more prone to rest. Overall, the in vitro micrografting technique used appeared to be an helpful tool for vegetative non-destructive propagation of mature selected Acacia mangium ortets, apparently recalcitrant to more conventional in vivo grafting techniques. These results are discussed in terms of scion size and the related potential for grafting in relation to the age ofthe ortet. (Resume d'auteur)
Estimating overidentified, nonrecursive, time‐varying coefficients structural vector autoregressions

This paper provides a general procedure to estimate structural vector autoregressions. The algorithm can be used in constant or time‐varying coefficient models, and in the latter case, the law of motion of the coefficients can be linear or nonlinear. It can deal in a unified way with just‐identified (recursive or nonrecursive) or overidentified systems where identification restrictions are of linear or of nonlinear form. We study the transmission of monetary policy shocks in models with time‐varying and time‐invariant parameters.
The Best of Intentions? Managing Disasters and Constructions of Risk and Vulnerability in Asia

Drawing on research on landslide risk reduction in Nepal and the impacts of the Indian Ocean tsunami of 2004 in southern Thailand, this paper considers how risk, in the context of natural hazards, is produced by processes of social and economic transformation; understood and experienced by vulnerable groups; and framed by governments and experts. In so doing, we propose an agenda for more effective disaster risk management. We open the discussion by exploring the spatiality of risk, vulnerability and opportunity in the two research contexts, in particular, why people live in hazardous places and the processes that explain the intersection of human settlement and livelihoods on the one hand, and risk on the other. The paper then turns to consider the way that “risk”—and the framing and prioritisation of risk(s) by governments, experts and by vulnerable groups themselves—plays a role in setting the disaster risk management agenda. Underpinning this is the hidden question of what evidence is used—and valued—in the identification and delineation of risk. In order to understand disaster vulnerability, we argue that it is necessary to look beyond the immediate “hazardscape” to understand the wider risk context both spatially and structurally. Effective disaster risk management requires not only an appreciation of the different framings and understandings of risk, but a true integration of knowledge and expertise.

The Journal of Supercritical Fluids

The goal of this paper is to show that the wetting behavior of simple fluids on a repulsive solid surface – especially the “drying” phenomenon – is closely related to the proximity of the supercritical state of the bulk fluids to their vapor–liquid coexistence region. We propose here a new DFT (the star-function based density functional theory, s-DFT) that is based on the functional Taylor expansion of the intrinsic free energy F[ ] and the singlet direct correlation C w (r) to arrive at closed-form expressions for both quantities without truncations or approximations. The two formulas are mutually consistent because of the introduction of a star function Sw that has been shown to be the functional primitive of the bridge function Bw , i.e. ıS∗ w/ı = Bw (L.L. Lee, J. Chem. Phys. 97 (1992) 8606 [34]). The new formulation is applied to the Lennard-Jones molecules adsorbed on a planar hard wall (LJ/HW). We carried out new Monte Carlo simulations for this system. Since the s-DFT uses a bridge function Bw , we demonstrate (i) the existence of a set of data (inverted from the MC information) that can perform as the bridge function and reproduce accurately the density profiles (1) w (r); (ii) this set of data can be “fitted” by a function-form with acronym ZSEP; finally (iii) ZSEP expresses the bridge function Bw in terms of a new renormalized basis function H, i.e. Bw( H). The existence of a bridge function dispels some of the misconceptions that the bridge-function based formulations did not describe the “drying” behavior. We also show that for the high density case ZSEP equation can qualify as a “closure relation”, but seems to deteriorate for the two low-density supercritical states that are close to the bulk saturated liquid phase boundaries. © 2010 Elsevier B.V.

Joint Measurement of Localization and Detection of Sound Events

Sound event detection and sound localization or tracking have historically been two separate areas of research. Recent development of sound event detection methods approach also the localization side, but lack a consistent way of measuring the joint performance of the system; instead, they measure the separate abilities for detection and for localization. This paper proposes augmentation of the localization metrics with a condition related to the detection, and conversely, use of location information in calculating the true positives for detection. An extensive evaluation example is provided to illustrate the behavior of such joint metrics. The comparison to the detection only and localization only performance shows that the proposed joint metrics operate in a consistent and logical manner, and characterize adequately both aspects.
SEROPREVALENCE OF Mycoplasma gallisepticum IN NON VACCINATED BROILER FLOCKS IN ABBOTTABAD KHYBERPAKHTUNKHWA, PAKISTAN

Mycoplasma gallisepticum (MG) is the contributory agent of chronic respiratory disease (CRD) in the commercial poultry world including Pakistan. The breathing ailments in the broiler flocks are upsetting the poultry economics. The study was designed to investigate seroprevalence of Mycoplasam gallisepticum (MG) during the period of May to September 2017. The infected birds showed different clinical signs i.e. coughing, sneezing, rales and exudate from nostrils and eyes. Blood samples (n=360) were collected from selected areas of Abbottabad, Khyberpakhtunkhwa viz; Qalanderabad, Abbottabad central and Havellian due to its rich broiler population. Serum Plate Agglutination Test (SPAT) and Enzyme Linked Immunosorbent Assay (ELISA) were used to determine the prevalence of MG. Serum samples (n=57) were found positive through SPAT (15.8%) and samples (n=29) were found positive through ELISA (8.5%). The age of bird affected the occurance of Mycoplasma gallisepticum infection in broilers. Infection was more prevalent between the age of 20-30 days Viz; 29.1% and 23.6% through SPAT & ELISA respectively.The prevalence was lowest in first three weeks of age. However, infection prevailed throughout the flock rearing at various levels. Climatic conditions affected the occurance of Mycoplasama gallisepticum infection. A high prevalence of 23.6% & 29.1% through ELISA & SPAT respectively was observed in the month of August (Table 2). Infection was comparitively lower in the months where humidity level was low i.e. May June and July due to less frequent rain patterns. The prevalence of infection was highest in qalandrabad area followed by Abbottabad central and Havelian area. The ELISA protocols were found more specific and SPAT was more sensitive test for Mycoplasama gallisepticum antibodies.
