description: Field experiments were conducted to study the response of garlic cv. Multiclove local to different combinations of S, B, Zn and cowdung (CD) with NPK in the Gangachara soil series of Tista Meander Floodplain, Rangpur in two consecutive years. There was a significant influence of fertilizers on yield attributes and yield of garlic. The results were consistent over the years. NPK were more effective in combination with S and B in increasing the bulb yield. Zinc had no significant effect on bulb yield. The highest profitable bulb yield (5.75 t/ha) was produced by the combined application of NPKSBZn with the maximum benefit and the highest marginal rate of return (2741%). The effects of NPKSB, NPKSB+CD and NPKSBZn+CD on bulb yield and economic return were, however, statistically similar to NPKSBZn. For sustainace of soil health with higher yield, application of fertilizer along with organic manure like NPKSB+CD is important.

description: There remain significant uncertainties in the origin and evolution of black holes in binary systems, in particular regarding their birth sites and the influence of natal kicks. These are long-standing issues, but their debate has been reinvigorated in the era of gravitational wave detections and the improving precision of astrometric measurements. Using recent and archival characterisation of Galactic black hole X-ray binaries (BHXBs), we report here an apparent anticorrelation between P{orb} (system orbital periods) and scatter in z (elevation above the Galactic plane). The absence of long period sources at high z is not an obvious observational bias, and two possible explanatory scenarios are qualitatively explored: (1) a disc origin for BHXBs followed by natal kicks producing the scatter in z, with only the tightest binaries preferentially surviving strong kicks; (2) a halo origin, with P{orb} shortening through dynamical interactions in globular clusters (GCs). For the latter case, we show a correspondence in z-scatter between BHXBs and the GCs with most compact core radii of <0.1pc. However, the known absence of outbursting BHXB transients within Galactic GCs remains puzzling in this case, in contrast to the multitude of known GC neutron star XRBs. These results provide an interesting observational constraint for any black hole binary evolutionary model to satisfy.

Variation in resolution and sensitivity caused by intercalation dyes in capillary electrophoretic separations of DNA fragments
Creators: name: Marino, Jr., Michael Anthony
Publisher: name: American University
Year: 2023

description: Capillary electrophoresis (CE) is a high resolution analytical technique which provides an alternative to traditional slab gel methodologies. Analysis time is faster due to the efficient heat dissipation of the capillary, allowing for the use of higher applied voltages. CE also offers many on-column detection modes. DNA can be separated and detected using CE with UV absorption detection at 260 nm, but with limited sensitivity. An alternative detection scheme with increased sensitivity, is laser-induced fluorescence (LIF) detection. This requires that the DNA fragments be PCR-amplified using fluorescent labeled primers, or stained on-column using intercalation dyes. This work describes the analysis of short tandem repeat (STR) loci THO1, F13A01 and vWFA31 alleles intercalated with monomeric and dimeric intercalation dyes and separated using CE with LIF detection. The alleles were purified using high performance liquid chromatography (HPLC) to ensure only the desired fragment was present for each sample analysis. These fragments were used to evaluate the absorbance changes of DNA and the fluorescence changes of the dyes after intercalation as a function of base pair to dye concentration. The electrophoresis of the DNA fragments intercalated before injection onto the CE column resulted in loss of resolution and sensitivity when compared to the on-column labeling technique. The study of dye-DNA complexes during electrophoresis required the development of a fluorescently labeled single stranded DNA standard. The results of these experiments were then applied to an STR typing assay. Using this typing assay, the 9 and 9.3 alleles of the THO1 locus were separated with a resolution of 0.49. This CE analysis, using on-column intercalation with a separation polymer containing $250\times10\sp{-6}$ mM TOTO-1, was complete in less than 20 minutes, and the only sample preparation necessary was a dilution step where the PCR product was diluted one to four thousand prior to CE analysis.

description: The letter resolves several intriguing and fundamental aspects of debonding at soft interfaces, including the formation and persistence of regularly arranged nanocavities and bridges, ``adhesion-debonding hysteresis'', and vastly lower adhesive strengths compared to the absence of pattern formation. The analysis shows the hysteresis to be caused by an energy barrier that separates the metastable patterned configurations during withdrawal, and the debonded state. The metastable morphological pathways involving cavitation and peeling of contact zones engender substantially lower debonding forces.

description: Using events in which one of two neutral-B mesons from the decay of an Y(4S) resonance is fully reconstructed, we set limits on the difference between the decay rates of the two neutral-B mass eigenstates and on CP, T, and CPT violation in B0-antiB0 mixing. The reconstructed decays, comprising both CP and flavor eigenstates, are obtained from 88 million Y(4S) --> Banti-B decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We determine six independent parameters governing oscillations (Deltam, DeltaGamma/Gamma), CPT and CP violation (Re Z, Im Z), and CP and T violation (Im lambdaCP, |q/p|), where lambdaCP characterizes B0 and anti-B0 decays to states of charmonium plus K0S or K0L. The results are sgn(Re lambdaCP)xDeltaGamma/Gamma = -0.008 +/- 0.037(stat) +/- 0.018(syst) [-0.084,0.068], |q/p| = 1.029 +/- 0.013(stat) +/- 0.011(syst) [ 1.001,1.057], (Re lambdaCP)/|lambdaCP|xRe z = 0.014 +/- 0.035(stat) +/- 0.034(syst) [-0.072,0.101], Im z = 0.038 +/- 0.029(stat) +/- 0.025(syst) [-0.028,0.104], The values inside square brackets indicate the 90% confidence-level intervals. The values of Im lambdaCP and Deltam are consistent with previous analyses and are used as cross-checks. These measurements are in agreement with Standard Model expectations.

Research on privatization of airport traffic control towers: Contracting out level I VFR airport traffic control towers

description: In 1982, the Federal Aviation Administration (FAA) created the Low Activity I VFR Control Tower Program (Tower Program). The Tower Program made it possible to contract out the operation of the level I VFR ATCTs, which were operated only by the FAA. The primary research question is whether contracting out airport traffic control towers (ATCTs) can reduce the operation costs without sacrificing air traffic safety. To answer this question, two different types of models are tested: cost models and outcome (safety) models. After testing the primary research hypotheses, this research tries to answer why the implementing process of contracting out level I ATCTs has been so long delayed by the FAA. The statistical tool for the cost models is multiple regression analysis based on ordinary least square (OLS) estimation. The OLS and weighted least square (WLS) are employed to test the outcome models. The unit of analysis in both costs and outcome models is level I VFR ATCTs. The main data were collected by mail order to FAA regional offices. The results of cost models indicates that the annual operation of contractor ATCTs costs much less than that of FAA VFR level I ATCTs. It is possible that difference in a total annual operation costs between FAA Level I VFR ATCTs and contractor ATCTs results from a difference in the number of staff, but this study cannot test this conjecture because contractor towers did not provide data on staff. Moreover, the statistical results of the outcome models show that the safety record of contractor ATCTs is not inferior to that of FAA-operated ATCTs. In conclusion, the FAA may not make full use of staff members while the contractor may more efficiently allocate each staff. The FAA's seemingly inefficient use of staff (overstaffing) results not only from the lack of well-specified outcome (appropriate safety indicators), but also from the ineffective congressional oversight. This research also argues that the delay of implementing the Tower Program is due to political factors rather than economic reasons.
Modeling Lead-Rubber Seismic Isolation Bearings Using the Unified Mechanics Theory

Subjects: subject: Applied Physics (physics.app-ph)
subject: FOS: Physical sciences

description: Lead-rubber seismic isolation bearings (LRB) have been installed in a number of essential and critical structures, like hospitals, universities and bridges, located in earthquake-prone areas. The purpose of using LRB is providing the structure with period lengthening and the capacity of dissipating a considerable amount of earthquake energy to mitigate the effects of strong ground motions. Therefore, studying the damage mechanics of this kind of devices is fundamental to understand and accurately describe their thermomechanical behavior, so that seismically isolated structures can be designed more safely. Traditionally, up to this point, the hysteretic behavior of LBR has been modeled using 1) Newtonian mechanics and empirical curve fitting degradation functions, or 2) heat conduction theories and idealized bilinear curves which include degradation effects. The reason for using models that are essentially phenomenological or that contain some adjusted parameters is the fact that universal laws of motion by Newton lack the term to account for degradation and energy loss of a system. In this paper, the Unified Mechanics Theory, which integrates laws of Thermodynamics and Newtonian mechanics at ab-initio level, is used to model the force-displacement response of LRB. When Unified Mechanics Theory is used, there is no need for curve fitting techniques to describe the degradation behavior of the material. Damage or degradation at every point is calculated using entropy generation and the physics based fundamental equations of the material along the Thermodynamics State Index (TSI) axis. A finite element model of a lead-rubber bearing was constructed in ABAQUS, where a user material subroutine UMAT was implemented to define the Unified Mechanics Theory equations and the viscoplastic constitutive model for lead. Finite element analysis results were compared with experimental test data.

description: An investigation on abundance of storage insects of rice seeds and loss assessment were made In Aman during February to July, 2002 and Boro during May to October, 2002 in different storage structures viz. Dole, Motka, Kolshi, Steel Drum, Kerosene Tin, Polythene/Plastic Bag, Gunny Bag and Plastic Drum at three villages of Mymensingh Sadar upazila. Analysis of seed sample of 250g from each storage structure at monthly interval showed four insect species namely, Sitotroga cerealella Oliv., Rhizopertha dominica Fab., Sitophilus oryzae L. and Tribolium castaneum Hebst. Higher insect population was recorded in Boro seeds. In Aman, the mean number of S. cerealella, R. domonica, S. oryzae, T. castaneum was recorded as 13.8, 2.1, 0.38, 0.6, respectively and in Boro, it was 18.6, 1.6, 2.7, 1.0 in 250g of seeds, respectively. The highest insect population, seed damage and weight loss were recorded in Gunny Bag and the lowest were in metal structures (Steel Drum in Aman or Kerosene Tin in Boro) followed by Polythene/Plastic Bag. Seed damage and weight loss was increased with storage period in Aman but decreased after initial increase in Boro. Highest moisture content was also found in Gunny Bag. More than 80% germination was recorded in all structures except in Gunny Bag in both seasons after six month. The germination was decreased with increasing storage period. Therefore, the storage structures, Steel Drum, Kerosene Tin and Polythene/Plastic Bag could be used for safe storage of rice seeds.

In contrast to the recent paper, in which the su(2)-algebra plays a central role, in this paper, the su(1,1)-algebra is in a central position. The orthogonal set obtained in this paper is expressed in terms of monomial with respect to the state generating operators.

description: We numerically simulated quantum turbulence in superfluid $^4$He to investigate the emission of vortex rings from a localized vortex tangle. Turbulence is characterized by some universal statistical laws. Although there are a lot of studies on statistical laws in bulk quantum turbulence, studies in inhomogeneous or localized turbulence is scarce. We first investigate the statistical laws of localized quantum turbulence, referring to two statistical laws deduced from the vibrating wire experiments in [Yano $et$ $al.$, J. Low Temp. Phys. $\bf{196}$, $184\ (2019)$]. The first law is the Poisson process for the detection of vortex rings; the vortex tangle emits vortex rings with frequencies depending on their sizes. The second law is the power law between the frequency and the size of the emitted vortex rings, showing the self-similarity of the tangle. To study these statistical laws numerically, we developed a system similar to experiments. First, we generate a localized statistically steady vortex tangle by injecting vortex rings from two opposite sides and causing collisions. We investigated the conditions that aid the formation of the tangles and the anisotropy of the emission of vortex rings from the tangle. Second, from the data on emitted rings, we reconstruct the two statistical laws. Results from our numerical investigations are consistent with the known self-similarity of emitted vortex rings and localized tangles.

description: Carbofuran (Furadan®, 5G, Padma Oil Company Ltd, Bangladesh) at different five doses i.e. 0.4, 4, 8, 12 and 16 mg/kg body, weight were administered orally to five groups of adult guinea pigs (each group consisting of 5 guinea pigs) for studying the toxic symptoms and lethality, haemato-biochemical Parameters & treatment of its toxicity in guinea pigs. The lowest dose i.e. 0.4 mg/kg dose of carbofuran Was found to be non toxic for adult guinea pigs. However, the dose of 4 mg/kg body weight of carbofuran was found to be toxic without causing any mortality. Whereas the higher three doses i.e. 8, 12 and 16 mg/kg body weight caused 40, 80 and 100% mortality respectively. The toxic symptoms Produced by carbofuran treated guineapigs were restlessness, nasal secretion, sneezing, frothy salivation, incoordination, opisthotonus, shivering, muscular fasciculation, respiratory distress, recumbencey, distended abdomen and muscular paralysis, which were characteristic of anti-ChE (Cholinesterase) poisoning. Based on mortality rate, the oral acute LD50 was calculated as 7.5mg/kg body weight in adult guinea pigs. The activities of SGPT and SGOT were increased significantly (p<0.01) to extent of 22-119% and 48-114% respectively following higher four doses of carbofuran (4, 8, 12 and 16 mg/kg b.wt.). Similarly, total leukocyte count (TLC) was increased significantly (p<0.01) upto 4-26% following higher four doses. On the other hand total erythrocyte count (TEC) and haemoglobin (Hb) content were decreased significantly upto 6-30% and 7-31% respectively following higher four doses of carbofuran (4-16 mg/kg). Packed cell volume (PCV) values were not altered following any of the five doses of carbofuran. Blood glucose level was significantly increased (p<0.01) to the extent of 9- 26% following four doses of Furadan® (4-16 mg/kg bwt.), whereas glucose level was unaffected following nontoxic dose (0.4 mg/kg b.wt.) In survivors, the altered biochemical and hematological values returned to pre-exposure level within 7-14 days of insecticide feeding. On comparing the therapeutic efficacy between atropine sulphate alone and atropine sulphate plus taste) (frusemide), it could be concluded that the combined therapy was found to be better against Furadan® poisoning in guinea pigs.

description: In the framework of the analytic approach to Quantum Chromodynamics a new model for the strong running coupling has recently been developed. Its underlying idea is to impose the analyticity requirement on the perturbative expansion of the renormalization group $β$ function for restoring the correct analytic properties of the latter. The proposed model possesses a number of appealing features. Namely, the analytic invariant charge has no unphysical singularities at any loop level; it contains no free parameters; it has universal behavior both in ultraviolet and infrared regions at any loop level; and it possesses a fair higher loop and scheme stability. The extension of this model to the timelike region revealed the asymmetrical behavior of the running coupling in the intermediate- and low-energy domains of spacelike and timelike regions, that is essential when one handles the experimental data. The developed approach enables one to describe, in a consistent way, various strong interaction processes both of perturbative and intrinsically nonperturbative nature.

description: Palestinian employment in Israel has benefited for a long time both Palestinian and Israeli economies. However, this win-win situation is hampered by the tight security-related restrictions introduced by Israel in the 1990s. Assuming that in a final settlement of the conflict those restrictions will be reduced, this paper uses a CGE framework including a new and comprehensive database to assess the effects of restoring the Palestinian employment in Israel to its pre-intifada level. The results show a strong reduction in Palestinian unemployment, strong welfare improvements for households and substantial changes in the composition of the labor force in the domestic labor market.

description: This story map explores the nature of historic place-names across what is currently Mexico, introducing the importance of place-names and language as a tool of colonisation and empire. The story map explores how this tool was used not only by the Spanish, but also by the Mexica and the Triple Alliance (not to mention other indigenous groups), as part of their systematic colonisation of conquered settlements and people. The story map goes on to explore how indigenous place-names continued to be used, despite the processes of colonisation at the hands of both the Triple Alliance and the Spanish. In addition, it explores the meaning of Nahua toponymy in particular – demonstrating the use of suffixes such as -tepec (which means ‘inhabited place’) and showing the distribution of some of these examples. Following this are some case studies of individual place-names, explaining their meaning and how they have been depicted in the historical record. The story map concludes by giving a brief overview of colonial naming, and how indigenous influences have continued.
President Reagan's New Federalism and social inequality: An analysis of county government social welfare expenditures
Creators: name: Wu, Ke Bin
Publisher: name: American University
Year: 2023

description: This research brings into focus the impacts of President Reagan's "New Federalism" on the Americans social welfare system and extends the scholarship on the relationship between Reagan's New Federalism and social inequality. It examines trends in federal government financial aid to county governments and county government expenditures during the 1980s. Specifically, data from the U.S. Bureau of the Census Annual Survey of Government Financial Statistics are employed to analyze the relationship between financial aid to county governments and changes in disparity of county government expenditure among types of counties in the state of North Carolina during the 1980s. The Reagan Administration cut federal financial aid to states and localities substantially in the 1980s, leading to state and local government financial difficulty, especially for poor areas where governments were more reliant on federal financial aid. As a result, disparity of county government expenditures among different counties increased. The conceptualization of social inequality in terms of disparity in per capita county government expenditures represents an expansion in the way scholars have looked at inequality in Americans social economic well being. Federal government reduces social inequality not only through federal tax policy and entitlement programs, but also through federal financial aid to states and local governments to help poor jurisdictions provide national standard social services and social welfare assistance. Social equity requires that Americans under the same circumstances but living in different jurisdictions should have equal opportunity to access and receive the same standard of social service and social welfare assistance. The results from this research suggest that: Cuts in federal financial aid to county governments under Reagan's New Federalism weakened the equalization function of federal grants-in-aid. As a result, social inequality, measured by per capita county government general expenditure and per capita social welfare expenditures for persons in poverty, increased among the three types of counties in the state of North Carolina. In light of these research results, policy makers should not focus just on government efficiency, but should also be concerned about social inequality, especially for the poor who need social welfare assistance.

description: Abstract
 In the novel, fictional authority relies above all on the maintenance of a « pragmatic verisimilitude » (Cécile Cavillac) assuring the reader that the narrator is knowledgeable, competent and reliable. In the second half of the French eighteenth century, the constraints imposed by this verisimilitude persists but also undergoes certain changes. This is evident in the decriptive practice that can be found in the novels, descriptions being sometimes a threat, but sometimes also a supporting element, to fictional authority. Based on the descriptive practice that can be observed in novels by Castilhon, Nerciat, Tiphaigne de la Roche and Diderot, this contribution aims to study this ambivalence and to show the relation between description and narration in the eighteenth century novel. Résumé en français
 Dans l’univers du roman, l’autorité fictionnelle repose notamment sur l’établissement d’une « vraisemblance pragmatique » (Cécile Cavillac) qui assure le lecteur des connaissances, de la compétence et de la fiabilité du narrateur. Dans la seconde moitié du XVIIIe siècle français, les contraintes qu’impose cette vraisemblance persistent tout en subissant des transformations. Ainsi le révèle la pratique descriptive en se présentant tantôt comme un écueil de l’autorité narrative, tantôt comme un élément de soutien à cette autorité. S’appuyant sur la pratique descriptive dans certains romans de Castilhon, Nerciat, Tiphaigne de la Roche et Diderot, la présente contribution entend étudier cette ambivalence de la pratique descriptive et d’en dégager les enjeux pour la pratique narrative de l’époque.

description: The multiresolution diffusion entropy analysis is used to evaluate the stochastic information left in a time series after systematic removal of certain non-stationarities. This method allows us to establish whether the identified patterns are sufficient to capture all relevant information contained in a time series. If they do not, the method suggests the need for further interpretation to explain the residual memory in the signal. We apply the multiresolution diffusion entropy analysis to the daily count of births to teens in Texas from 1964 through 2000 because it is a typical example of a non-stationary time series, having an anomalous trend, an annual variation, as well as short time fluctuations. The analysis is repeated for the three main racial/ethnic groups in Texas (White, Hispanic and African American), as well as, to married and unmarried teens during the years from 1994 to 2000 and we study the differences that emerge among the groups.

description: We study the dynamics of solitons under the action of one-dimensional quasiperiodic lattice potentials, fractional diffraction, and nonlinearity. The formation and stability of the solitons is investigated in the framework of the fractional nonlinear Schrödinger equation. By means of variational and numerical methods, we identify conditions under which stable solitons emerge, stressing the effect of the fractional diffraction on soliton properties. The reported findings contribute to the understanding of the soliton behavior in complex media, with implications for topological photonics and matter-wave dynamics in lattice potentials.

description: This research brings into focus the impacts of President Reagan's "New Federalism" on the Americans social welfare system and extends the scholarship on the relationship between Reagan's New Federalism and social inequality. It examines trends in federal government financial aid to county governments and county government expenditures during the 1980s. Specifically, data from the U.S. Bureau of the Census Annual Survey of Government Financial Statistics are employed to analyze the relationship between financial aid to county governments and changes in disparity of county government expenditure among types of counties in the state of North Carolina during the 1980s. The Reagan Administration cut federal financial aid to states and localities substantially in the 1980s, leading to state and local government financial difficulty, especially for poor areas where governments were more reliant on federal financial aid. As a result, disparity of county government expenditures among different counties increased. The conceptualization of social inequality in terms of disparity in per capita county government expenditures represents an expansion in the way scholars have looked at inequality in Americans social economic well being. Federal government reduces social inequality not only through federal tax policy and entitlement programs, but also through federal financial aid to states and local governments to help poor jurisdictions provide national standard social services and social welfare assistance. Social equity requires that Americans under the same circumstances but living in different jurisdictions should have equal opportunity to access and receive the same standard of social service and social welfare assistance. The results from this research suggest that: Cuts in federal financial aid to county governments under Reagan's New Federalism weakened the equalization function of federal grants-in-aid. As a result, social inequality, measured by per capita county government general expenditure and per capita social welfare expenditures for persons in poverty, increased among the three types of counties in the state of North Carolina. In light of these research results, policy makers should not focus just on government efficiency, but should also be concerned about social inequality, especially for the poor who need social welfare assistance.
Conditional Distributions of Crop Yields: A Bayesian Approach for Characterizing Technological Change

description: What changes in the distribution of crop yields occur as a result of technological innovation? Viewing observed yields as random variables, estimation of the yield distribution conditional on time provides one approach for characterizing distributional transformation. Yields are also affected by weather and other covariates, spatial correlation, and a paucity of data in any one location. Common parametric and nonparametric methods rarely consider these aspects in a unified manner. Comprehensive solutions for describing the distribution of yields can be considered ideal. We implement a Bayesian spatial quantile regression model for the conditional distribution of yields that is distribution-free, includes weather (covariate) effects, smooths across space, and models the complete quantile process. Results provide insight into the temporal and spatial evolution of crop yields with implications for the measurement of technological change. Acknowledgement :

description: Enhancement of flux pinning by magnetic nanoparticles embedded into the bulk of type-2 superconductor is studied both theoretically and experimentally. Magnetic part of the pinning force associated with the interaction between a spherical magnetic inclusion and an Abrikosov vortex was calculated in the London approximation. Calculations are supported by the experimental results obtained on sonochemically modified MgB2 superconductor with embedded magnetic Fe2O3 nanoparticles and compared to MgB2 with nonmagnetic Mo2O5 pinning centers of similar concentration and particle size distribution. It is shown that ferromagnetic nanoparticles result in a considerable enhancement of vortex pinning in large-kappa type-2 superconductors.

description: Chiral Higher Spin Gravity is unique in being the smallest higher spin extension of gravity and in having a simple local action both in flat and (anti)-de Sitter spaces. It must be a closed subsector of any other higher spin theory in four dimensions, which makes it an important building block and benchmark. Using the flat space version for simplicity, we perform a thorough study of quantum corrections in Chiral Theory, which strengthen our earlier results arXiv:1805.00048. Even though the interactions are naively non-renormalizable, we show that there are no UV-divergences in two-, three- and four-point amplitudes at one loop thanks to the higher spin symmetry. We also give arguments that the AdS Chiral Theory should exhibit similar properties. It is shown that Chiral Theory admits Yang-Mills gaugings with $U(N)$, $SO(N)$ and $USp(N)$ groups, which is reminiscent of the Chan-Paton symmetry in string theory.

description: Abstract With the expansion of large-scale forest plantations in developing countries, concerns are rising about their relation and integration with adjacent local communities. Local participation in forest governance can potentially affect the distributional effects of plantations benefits and mitigate their adverse effects. Using data from villages adjacent to plantations in Tanzania and Mozambique, we explore differences in local participation between plantations Our quantitative analyses show that households in villages adjacent to private certified plantations are more likely to have a say in the activities of the plantations than households in villages adjacent to non-certified or state owned plantations. We use insights from access theory to explain our findings: private plantations may have more incentives to involve local people to guarantee their investments in plantations than state-owned plantations. Certification requirements may also strengthen these incentives by requiring plantations to identify and uphold customary rights of local communities. We further found that some social groups (male-headed, more educated and plantation workers) are more likely to have a say in plantations activities than their counterparts. We emphasize that increased and fair local participation in governance of plantations is vital in terms of the sustainability of large-scale plantations and integrating them in rural landscapes. Key words: Forest plantations, local governance, participation, access , Tanzania, Mozambique Acknowledgement :
Purchase prices and abnormal returns in United States banking industry mergers and acquisitions: 1989--1995
Creators: name: Zhang, Xuechun

description: This study examines the purchase prices and the abnormal returns in mergers and acquisitions in the U.S. banking industry during 1989-95. It consists of two parts of empirical work. The first part, the comparison of deposit premiums paid in private branch sales with those in federally assisted failed institution sales, suggests that in the government-assisted failed branch sales, the FDIC and RTC subsidized the buyers of the failed-bank and thrift branches during 1989-91. After 1991, the deposit premium differences between the two types of deals were negligible, indicating that there may not be any government subsidization in the last four years of our observation period. Moreover, the two-stage ordinary least squares models show that the target's value is different for different buyers, which provides evidence for that the branch sales may be independent private value auctions. In addition, this paper shows that industry level variables are statistically significant in determining the purchase premium, which also holds true in the second part of the empirical work dealing with private whole bank and thrift mergers. The second part of the empirical study examines the merger prices and the abnormal returns (ARs) of the private whole bank and thrift transactions. Not surprisingly, the current study finds that the merger prices (the ratio of tangible book value premium to core deposit) are significantly higher in the deals involving publicly traded buyers or sellers, which indicates that the capital market plays an important role in determining the merger price. The shareholders of the target firms gain large positive ARs after the transaction announcement, whereas the shareholders of the acquiring firms gain much less, although still positive returns from the merger. On average, the overall returns of the buyers and sellers are positive. Similar results are also confirmed by the seemingly unrelated regression (SUR) models. The study of ARs features a model that enables an analysis of the effects of consecutive deals made by the same buyers. The average AR resulting from the first deal is much higher than those of the second deal, implying that if a firm jumps to another deal before it can digest the previous transaction, the market shows its skepticism in the form of lower improvements in the buyer's stock price. However, once convinced of the buyer's ability in handling mergers and acquisitions, the market responds positively to its future deals, which is shown in the higher ARs in the third deals conducted by the same buyer. Nevertheless, we cannot draw a general conclusion on how previous deals affect the more recent transactions, because there is a wide dispersion in the measured ARs associated with "termed" deals.
