An Empirical Study on the Announcement of Corporate Quarterly Results in India

Announcement of quarterly results is the course of communicating the performance of a company to its owners. Investors’ long-term buying decisions are largely based on the earnings stream of the firm. In order to show the progress of the company, the earnings position is revealed as per the listing agreement at a regular interval. Normally a higher earnings than the previous quarter earnings should be welcomed by the market. This should be associated with greater return after the result is announced. All higher return after the announcement cannot say to be due to the earnings results. To find out the impact of results on returns, the impact of other factors in returns is to be segregated. The impact of other factors in return is taken from the index which is nothing but the market return. The announcement of earnings is unique and specific to a company, to study its impact on the market place, the impact of other factors is removed, that is why the period is limited to 32 days and the return is calculated for 31 days. This study examines abnormal returns of earnings announcement during the pre-announcement and post announcement period. This study is based on samples of 50 Nifty companies listed on National Stock Exchange, exhibited that investors do not gain value from earnings announcement. Indeed shareholders earned little value over a period of 15 days prior to the earnings announcement through to 15 days after the announcement. The lower return may be partially compensated because of the current earnings yield. This study also indicates that announcement of result does not convey any useful information to the investing community, which needs to be further investigated.
The splenic suppressor cell. II. Suppression of mixed lymphocyte reaction by thymus-dependent adherent cells.

3 H-thymidine incorporation was measured in mixed lymphocyte cultures of allogeneic rat spleen cells, the stimulating (donor) cells having been treated with mitomycin C (MC). Removal of adherent cells from either stimulating or reactive cells, or both, by passage through a glass wool column gave a substantial elevation of the response. The effect of such treatment of the stimulating cells could be duplicated by treating them with cycloheximide or by use of cells from doubly thymus-deprived donors. MC treatment, on the other hand, did not affect their supporessor activity. It was inferred that a subpopulation of splenic T cells adherent to glass wool act as suppressors in this immunologic system and that their action requires protein synthesis but not cell division. A close similarity was noted between these suppressor cells and those active in earlier experiments with PHA and concanavalin A and with suppressor cells studied in intact animals subjected to the graft-vs-host reaction. A general classification of suppressor cell systems is proposed.
The lease financing in Bangladesh: a satisfied progress in business and industrialization

This paper discusses the aspects of lease financing in Bangladesh. Bangladesh is a small but densely populated country in the South Asia and the people of it mainly depend on agricultural. Due to globalization and liberalization the country gradually shifting towards industrialization and lease becomes a pioneering and alternative way to develop the country through business and industrialization. Lease financing is the most important issue which determines the direction of financial behavior in an organization, a financial level of effort, and the organization’s level of perseverance in the face of obstacles of other types of financing. To develop leasing business in Bangladesh it is needed for its convenience and flexibility in financing. An attempt has been taken here to explore the lease financing of Bangladesh in some details.
Mechanisms of Tumor-Associated Edema: A Review

ABSTRACT: An understanding of the mechanisms responsible for tumor-associated edema involves the elucidation of the role played by a number of intra-related processes. These include (i) the permeability of new tumor microvessels that are associated with tumor angiogenesis; (ii) alterations in microvascular permeability due to factors secreted by tumor cells; (iii) immunological mechanisms and (iv) increased microvessel permeability associated with inflammation. The rationale for a role for inflammatory processes in tumor-associated edema has been outlined and the role of non-steroidal anti-inflammatory drugs in modulating experimental and human tumor-associated edema has been explored.
PI, GC, HP, and TF serum protein polymorphisms in Siena, Tuscany, Italy, with a review of data for Italy

The genetic polymorphism of four serum proteins (PI, GC, HP, and TF) is analyzed in a sample of 200 unrelated individuals from the province of Siena, Tuscany, central Italy. Siena is traditionally divided into 17 Contrade, that act as social units. The aim of this report is to ascertain whether this peculiar organization has led to genetic differentiation among the inhabitants of each Contrada and from other populations of Italy. For this purpose, the frequencies of genetic markers found in Siena are also compared with those reported for the same serum proteins in Italy based on provincial samples from the literature. The statistical analyses (heterozygosity estimates, F‐statistics, and cluster analysis) suggest that the Contrade represent only a cultural and historical institution without biological consequence and that the Italian population can be considered genetically homogeneous.

Anesthetic interaction with a model cell membrane: expansion, phase transition, and melting of the lecithin monolayer.

A synthetic L-α-dipalmitoyl lecithin monolayer at an air-water interface was used as a model to study the effects of volatile anesthetics on cell membranes. Methoxyflurane, chloroform, halothane, enflurane and fluroxene were used in this study. When the surface pressure of the monolayer was kept constant, anesthetics at clinically effective tensions expaned the area 0.5 per cent When the area of the monolayer was kept constant, the surface pressure was increased about 1.0 dyn/cm by anesthetics. This increase of the surface energy was caused by the addition of 2.70 x 1013 anesthetic molecules to one square cm of the interface. The surface pressure-surface area curve shows a discontinuity, and a transition from liquid-expanded phase to liquid-condensed phase occurs at this point The liquid-expanded phase is regarded as the “melted” state of the monolayer. Anesthetics shifted the phase transition point towards a more condensed region, indicating melting of the monolayer membrane. Anesthetics decreased the latent heat and entropy change of the phase transition, implying that anesthetics facilitate the melting of the membrane. The compressional modulus, a measure of the rigidity of the monolayer, was decreased by anesthetics. This decrease of rigidity, or increase of fluidity, was also disclosed by analysis of the hysteresis curve (surface pressure-surface area) obtained by compression and expansion of the monolayer. The results support the unfolding theory of anesthesia which postulates that disordering and
Comparison of PCR assay with bacterial culture for detecting Streptococcus pneumoniae in middle ear fluid of children with acute otitis media

We have studied etiological diagnosis of acute otitis media (AOM) by comparing a newly developed pneumococcal PCR for Streptococcus pneumoniae to bacterial culture with 180 middle ear fluid (MEF) samples of 125 children with 125 episodes of AOM. For pneumococcal PCR assay, DNA from MEF samples was extracted by phenol-chloroform. The outer primers used amplified a 348-bp region of the pneumolysin gene, and the inner primers amplified a 208-bp region. S. pneumoniae was cultured in 33 (18%) samples, and pneumolysin PCR was positive for 51 (28%) of 180 MEF samples. Only 2 of 21 PCR-positive, S. pneumoniae culture-negative samples were positive for other otitis pathogens. By combining MEF culture and PCR results, 54 (30%) of 180 MEF samples had evidence of pneumococcal etiology. In conclusion, pneumolysin PCR is a sensitive and specific new method to study pneumococcal involvement in MEF samples of children with AOM.

Histologic and ultrastructural analysis of regenerated bone in maxillary sinus augmentation using a porcine bone-derived biomaterial.

BACKGROUND The purpose of the present study was the histologic and ultrastructural evaluation of a biomaterial composed of cortical pig bone in the form of granules. METHODS After maxillary sinus augmentation using this biomaterial, 10 specimens were retrieved after 5 months in 10 patients using this biomaterial. The specimens were processed to be observed under light microscopy (LM) and transmission electron microscopy (TEM). Histomorphometric measurements were presented by means +/- standard deviations. RESULTS LM showed that most of the particles were surrounded by newly formed bone. In some areas, the osteoid matrix was present; however, mainly compact bone was present at the interface. There was no evidence of an acute inflammatory infiltrate. The newly formed bone was 36% +/- 2.8% and marrow spaces were 38% +/- 1.6%, whereas residual grafted material was 31% +/- 1.6%. Under TEM, all phases of bone formation (osteoid matrix, woven, and lamellar bone) were observed in proximity with the biomaterial particles. The bone-biomaterial interface showed a close contact between the porcine bone particles and the surrounding bone that had mainly features of mature bone with numerous osteocytes. A lamina limitans was sometimes present at this interface. CONCLUSIONS According to our knowledge, this is the first study presenting data on TEM of a porcine bone-derived biomaterial used in sinus augmentation procedures in humans. Our findings show that this is a biocompatible biomaterial that can be used for maxillary sinus augmentation procedures without interfering with the normal reparative bone processes.
DOES IT-OUTSOURCING INCREASE FIRM SUCCESS? A FIRM-LEVEL INVESTIGATION FOR GERMANY

Using German firm-level data, an endogenous switching regression model is employed for labor productivity and firms' decision to source out basic IT-services. This approach allows to take account of complementarities between IT-outsourcing and production input factors. Estimation results show that IT-outsourcing firms produce significantly more efficient than non-outsourcing firms. Furthermore, they have a significantly larger output elasticity of ICT-capital. The second part of this paper shows that in the medium term, IT-outsourcing has a weakly significant but positive effect on firms labor force growth rate.
Unintended costs and consequences of school closures implemented in preparation for Hurricane Isaac in Harrison County School District, Mississippi, August-September 2012

Introduction School closures, while an effective measure against the spread of disease during a pandemic, may carry unintended social and economic consequences for students and families. We evaluated these costs and consequences following a 4-day school closure in Mississippi’s Harrison County School District (HCSD). Methods In a survey of all households with students enrolled in HCSD, we collected information on difficulties related to the school closure, including interruption of employment and pay, loss of access to subsidized school meals, and arrangement of alternative childcare. We analyzed this information in the context of certain demographic characteristics of the survey respondents and households, such as race, level of education, and income. We also estimated the average number of lost work days and documented the childcare alternatives chosen by households affected by the school closure. Results We received 2,229 (28.4%) completed surveys from an estimated 7,851 households eligible to participate. About half (1,082 [48.5%]) of the households experienced at least some difficulty during the closure, primarily in three areas: uncertainty about duration of the closure, lost income, and the effort of arranging alternate childcare. Adults working outside the home, particularly the major wage earner in the household, were more likely to suffer lost income while schools were closed, an effect mitigated by paid leave benefits. Difficulty arranging childcare was reported most frequently by respondents with lower levels of education and households with younger children. Beyond the top three concerns expressed by households in HCSD, the survey also shed light on the issue of food insecurity when subsidized school meals are not available. Reported by 17.9% of households participating in the subsidized school lunch program, difficulty providing meals during the closure was associated with higher numbers of dependent children, selection of “other” as the race of the household respondent, and lower levels of education. Conclusion To help prevent undue financial hardship in families of school children, public health authorities and school administrators should provide recommendations for childcare alternatives and paid leave or remote work options during prolonged school closures, particularly to households in which all adults work outside of the home.
A Comparison of Variational Bayes and Markov Chain Monte Carlo Methods for Topic Models

Latent Dirichlet Allocation (LDA) is Bayesian hierarchical topic model which has been widely used for discovering topics from large collections of unstructured text documents. Estimating posterior distribution of topics as well as topic proportions for each document is the goal of inference in LDA. Since exact inference is analytically intractable for LDA, we need to use approximate inference approaches such as mean-field variational Bayes or MCMC methods. In this paper, efficiency and computational challenges of these approximate inference methods have been compared by conducting a simulation study on two high dimensional data sets. Experimental results show that, MCMC methods perform better than variational Bayes in terms of test-set likelihood and classification accuracy. But, this gain in performance comes with a huge increase in computation time. Results also suggest that mean-field variational Bayes can achieve a reasonable performance despite the high dimensionality of the problem and the factorized form of variational distribution.

ACTIVITY OF ASPARTATE AMINOTRANSFERASE AND ALANINE AMINOTRANSFERASE WITHIN WINTER TRITICALE SEEDLINGS INFESTED BY GRAIN APHID (SITOBION AVENAE F.)

Amino acid level is well known indicator of plant resistance to aphids. Our earlier studies showed that grain aphid (Sitobion avenae F.) infestation caused changes in the activity of the enzymes connected with amino acid biosynthesis and the transformation to defensive secondary metabolites within triticale tissues. However, there are not data on the significance of aminotransferases in these processes. The aim of our study was the quantification of changes in the activity of aspartate aminotransferase (AspAT) and alanine aminotransferase (AlaAT) in winter triticale seedlings caused by the feeding of the grain aphid. The study results showed that aphid feeding caused an increase in AlaAT activity and a decrease in AspAT activity within tissues of the triticale. The induced mechanisms of the triticale resistance to the grain aphid are discussed.
A Delphi forecast for the Singapore tourism industry: future scenario and marketing implications.

This article attempts to ascertain the future scenario of the Singapore tourism industry through the use of the Delphi technique. Two panels were established for the purpose of this study. The first panel consisted of key individuals in the local tourist industry. The second panel comprised an international group of executives participating in an executive development programme in Singapore. The panels were asked to examine a host of events related to the tourism industry in Singapore and to provide their assessments on the likelihood of these events happening in different time horizons. Based on the findings, events with higher probability of occurrence and crucial to tourism development are identified. Marketing implications of these events are discussed and strategies for tourism planning suggested.
Toxicoderma Secondary to 5-Fluorouracil: Differential Diagnosis ofParaneoplastic Pemphigus

We present the case of a patient undergoing chemotherapy with 5-Fluorouracil (5-FU), irinotecan and cetuximab, who presented polymorphous skin lesions with oral and genital mucosal involvement. The differential diagnosis included paraneoplastic pemphigus, a severe autoimmune disease associated with neoplasms. The histology can be variable with acantholysis or lichenoid dermatitis. The presence of circulating antibodies supports the diagnosis. In our case, the anatomopathological and immunological findings and the clinical improvement after the suspension of 5-FU confirmed that it was toxicoderma secondary to the latter.
Biomarkers in patients with acute dyspnoea: what for?

This editorial refers to ‘Mid-regional pro-atrial natriuretic peptide and pro-adrenomedullin testing for the diagnostic and prognostic evaluation of patients with acute dyspnoea’, by R.V. Shah et al. , doi:10.1093/eurheartj/ehs136 When patients present with acute dyspnoea, clinicians are faced with relevant issues. Particularly, making the right diagnosis and choosing the best therapies in a timely manner are crucial. To assess the latter, it may help to know the patient's risk, both short and long term, but the direct clinical benefit is less certain. History, physical examination, lab testing, and imaging techniques are cornerstones in order to come to the right conclusions, but they leave important open questions. Biomarkers circulating in the blood are attractive tools to improve care since they represent underlying pathophysiological processes and are relatively easy to measure. However, the question remains of what is their actual role in the clinical setting of acute dyspnoea ( Figure 1 ). Figure 1 Potential clinical usefulness of biomarkers (right-hand side) in the process of heart failure (left-hand side) with respect to diagnosis (green arrows), prognostic assessment (blue arrows), and therapy guidance (yellow arrows).

Determinants of export performance in a European context

Drawing attention to certain important gaps in the exporting literature, develops and evaluates a model of export performance using a sample of regular exporters from a small European Union country, in their trading activities with overseas distributors. Integrates and views specific firm characteristics, export commitment and export‐related perception variables as potentially important factors in explaining firm performance in the export market context. Tests the model in a three‐step procedure employing multiple regression analysis and identifies several elements that are related directly to export performance. Discusses the implications of the study for both business practitioners and public policy makers and highlights future research directions.
Fuzzy based unsupervised segmentation of textured color images

This paper proposes a fuzzy-based unsupervised segmentation of textured color images. L*a*b* color space is used to represent color features and statistical geometrical features (SGF) are adopted as texture descriptors. Homogeneity decision makes a fusion of texture features and color features with fuzzy-rule theory. Hierarchical segmentation based on the fuzzy homogeneity decision is performed in four processes: hierarchical splitting, local agglomerative merging, global agglomerative merging and pixelwise classification. Experiments on segmentation of color texture mosaics and color natural images are presented to verify the effectiveness of the proposed approach in obtaining rough segmentation.
Any complaints? A review of the framework of self-regulation in the Australian advertising industry

Prior to 1996, the Australian system of advertising self-regulation was regarded as a world model and many Asia-Pacific systems included components adapted from the Australian system. The recent changes to this system, encouraged by the abolition of the media accreditation system, consumer association pressure, criticism from the national advertisers association and the lack of a strong advertising agency presence, present an interesting framework in which to review the foundation concepts of self-regulation in advertising. This paper compares the new code of ethics with its predecessor and an international standard. It examines the performance of the code in terms of the number of complaints upheld and complaint by medium and product type and the voluntary response of advertisers. The findings suggest a weakening in the standard of advertising self-regulation in Australia, with fewer provisions in the Code of Ethics, a significantly fewer number of complaints upheld and no real power of enforcement. Although the case is Australian, it raises universal questions such as the vested interest of advertisers in controlling the process and roles of the consumer association, the media and the advertising agencies in guaranteeing the privilege of self-regulation.
Exploring the sales manager’s feedback to a failed sales effort

Observes that previous research on the value and effect of supervisory feedback has focused on the recipient of the feedback (the salesperson). The research reported in this article examines the feedback construct from the provider’s perspective (the sales manager). Explores the relationship between Sujan’s failed sales effort attribution model and the feedback provided typology developed by Jaworski and Kohli. The results confirm a direct relationship between failed sales effort attributed to poor strategy and positive feedback directed to salesperson behavior. A direct relationship is reported between the failed sales effort attributed to lack of effort (or intensity) and negative feedback provided by the sales manager that is directed to the salesperson’s output.
A Financial Health Therapy for Spanish Football: Stop the Bleeding and Capital Injection

European football in general and Spanish football in particular is experiencing huge financial difficulties. This paper analyzes Spanish clubs during the period from 2007 until 2011, using Altman’s models to classify clubs according to their Z-score values. A programming model is developed to estimate the values of the different variables included in the model required for clubs to demonstrate a sound financial condition. The evidence suggests that Spanish football is in very poor financial condition. To improve its situation what is required is a substantial injection of capital funding through issuing shares or asking for substantial contributions from members, increasing revenues, reducing wages and salaries and working to reduce current liabilities.
