Text summarization with harmony search algorithm-based sentence extraction

Currently vast amounts of textual information exist in large repositories such as Web. To processes such a huge amount of information, automatic text summarization has been of great interests. Unlike many approaches which focus on sentence or paragraph extraction, in this research, we introduce a method to make extractions based on three factors of Readability, Cohesion and Topic relation. We use Harmony Search-based sentence selection to make such a summary. Once the summary is created, it is evaluated using a fitness function based on those three factors. The evaluation of the algorithm on a test collection is also presented in the paper. Our results indicate that the extracted summaries by our proposed scheme have better precision and recall than the other approaches.
Waves of Indian IPOs: Evolution and Trend

Recent trend shows that Initial Public Offerings (IPOs) has become one of the popular and dependable methods of raising cash. This paper aims at understanding the waves and pattern of Indian IPOs. It was found that most of the IPOs were from private sector companies. The industry-wise trend in IPOs showed that most of the IPOs were launched by IT sector companies. It was observed that year 1999–2000 and year 2005–06 was best in terms of investors' response whereas the period from 2001 to 2003 was worst in terms of investors' optimism. Current waves of Indian IPOs are divided into hot market IPOs and cold market IPOs. A multivariate regression model is applied to empirically analyze issuers' approach to time their issue with hot market condition. The result suggests that Market timers, identified as firms that go public when the market is hot, tried to maximize the total proceeds at the time of IPO.
International Migration, Remittances, and the Brain Drain

Knowledge of the economic effects of migration, especially its impact on economic development, is rather limited. In order to expand knowledge on migration, and identify policies and reforms that would lead to superior development outcomes, this volume presents the results of a first set of studies carried out on the subject. Current demographic trends in both developed and developing countries are pointing toward significant, potential economic gains from migration. The labor forces in many developed countries are expected to peak around 2010, and decline by around 5 percent in the following two decades, accompanied by a rapid increase in dependency ratios. Conversely, the labor forces in many developing countries are expanding rapidly, resulting in declines in dependency ratios. This imbalance is likely to create strong demand for workers in developed countries' labor markets, especially for numerous service sectors that can only be supplied locally. There are large north-south wage gaps, however, especially for unskilled and semiskilled labor. Part 1 of this book, Migration and Remittances, examines the determinants of migration, and the impact of migration and remittances on various development indicators, and measures of welfare. Among these are poverty and inequality; investments in education, health, housing and other productive activities; entrepreneurship; and child labor and education. It focuses on different source countries, use data collected via different methodologies, and employ different econometric tools. Their results, however, are surprisingly consistent. Part 2, Brain Drain, Brain Gain, Brain Waste, focuses on issues related to the migration of skilled workers, that is, the brain drain. It presents the most extensive database on bilateral skilled migration to date, and also examines a number of issues associated with the brain drain, that have not been emphasized in the literature so far, uncovers a number of interesting and unexpected patterns, and, provides answers to some of the debates. This volume deals essentially with economically motivated south-north migration, whose principal cause is, in most cases, the difference in (the present value of) expected real wages, adjusted for migration costs.
What counts? An ethnographic study of infection data reported to a patient safety program.

CONTEXT Performance measures are increasingly widely used in health care and have an important role in quality. However, field studies of what organizations are doing when they collect and report performance measures are rare. An opportunity for such a study was presented by a patient safety program requiring intensive care units (ICUs) in England to submit monthly data on central venous catheter bloodstream infections (CVC-BSIs). METHODS We conducted an ethnographic study involving ∼855 hours of observational fieldwork and 93 interviews in 17 ICUs plus 29 telephone interviews. FINDINGS Variability was evident within and between ICUs in how they applied inclusion and exclusion criteria for the program, the data collection systems they established, practices in sending blood samples for analysis, microbiological support and laboratory techniques, and procedures for collecting and compiling data on possible infections. Those making decisions about what to report were not making decisions about the same things, nor were they making decisions in the same way. Rather than providing objective and clear criteria, the definitions for classifying infections used were seen as subjective, messy, and admitting the possibility of unfairness. Reported infection rates reflected localized interpretations rather than a standardized dataset across all ICUs. Variability arose not because of wily workers deliberately concealing, obscuring, or deceiving but because counting was as much a social practice as a technical practice. CONCLUSIONS Rather than objective measures of incidence, differences in reported infection rates may reflect, at least to some extent, underlying social practices in data collection and reporting and variations in clinical practice. The variability we identified was largely artless rather than artful: currently dominant assumptions of gaming as responses to performance measures do not properly account for how categories and classifications operate in the pragmatic conduct of health care. These findings have important implications for assumptions about what can be achieved in infection reduction and quality improvement strategies.
High-fi delity simulation increases obstetric self-assurance and skills in undergraduate medical students *

Objective: Teaching intrapartum care is one of the most challenging tasks in undergraduate medical education. Highfi delity obstetric simulators might support students ’ learning experience. The specifi c educational impact of these simulators compared with traditional methods of model-based obstetric teaching has not yet been determined. Study design: We randomly assigned 46 undergraduate medical students to be taught using either a high-fi delity simulator or a scale wood-and-leather phantom. Their self-assessments were evaluated using a validated questionnaire. We assessed obstetric skills and asked students to solve obstetric paper cases. Main outcome measures: Assessment of fi delity-specifi c teaching impact on procedural knowledge, motivation, and interest in obstetrics as well as obstetric skills using highand low-fi delity training models. Results: High-fi delity simulation specifi cally improved students ’ feeling that they understood both the physiology of parturition and the obstetric procedures. Students in the simulation group also felt better prepared for obstetric house jobs and performed better in obstetric skills evaluations. However, the two groups made equivalent obstetric decisions. Conclusion: This study provides fi rst data on the impact of high-fi delity simulation in an undergraduate setting.
Roles for the E4 orf6, orf3, and E1B 55-Kilodalton Proteins in Cell Cycle-Independent Adenovirus Replication

ABSTRACT Adenoviruses bearing lesions in the E1B 55-kDa protein (E1B 55-kDa) gene are restricted by the cell cycle such that mutant virus growth is most impaired in cells infected during G1 and least restricted in cells infected during S phase (F. D. Goodrum and D. A. Ornelles, J. Virol. 71:548–561, 1997). A similar defect is reported here for E4 orf6-mutant viruses. An E4 orf3-mutant virus was not restricted for growth by the cell cycle. However, orf3 was required for enhanced growth of an E4 orf6-mutant virus in cells infected during S phase. The cell cycle restriction may be linked to virus-mediated mRNA transport because both E1B 55-kDa- and E4 orf6-mutant viruses are defective at regulating mRNA transport at late times of infection. Accordingly, the cytoplasmic-to-nuclear ratio of late viral mRNA was reduced in G1 cells infected with the mutant viruses compared to that in G1 cells infected with the wild-type virus. By contrast, this ratio was equivalent among cells infected during S phase with the wild-type or mutant viruses. Furthermore, cells infected during S phase with the E1B 55-kDa- or E4 orf6-mutant viruses synthesized more late viral protein than did cells infected during G1. However, the total amount of cytoplasmic late viral mRNA was greater in cells infected during G1 than in cells infected during S phase with either the wild-type or mutant viruses, indicating that enhanced transport of viral mRNA in cells infected during S phase cannot account for the difference in yields in cells infected during S phase and in cells infected during G1. Thus, additional factors affect the cell cycle restriction. These results indicate that the E4 orf6 and orf3 proteins, in addition to the E1B 55-kDa protein, may cooperate to promote cell cycle-independent adenovirus growth.
Empirics on real convergence within European Union: Is growth in EU sustainable?

Empirical analysis of the real convergence between old (EU15) and new (EU8) economies is the basic focus of this paper, which should importantly contribute to the extensive empirical literature. The basic motivation for the present analysis is mixed results regarding the convergence process between EU8 and EU15 obtained by different authors. Important contribution to the mixed results is provided by different methodological frameworks used. Therefore, we apply cross-section, panel data and time series framework and test for real convergence between the EU8 and EU15 economies. The obtained results indicate statistically significant negative relationship between average growth of labour productivity and initial value of labour productivity level. However, there is clear absence of systematic convergence between EU8 and EU15 economies. This implies that individual economies from the EU23 group (i.e. EU8 + EU15) converge to its individual steady state, but both group of economies (EU8 and EU15) have different steady states. This result, however, provokes hypothesis that integration of former socialist economies (also termed as advanced transition economies) has not caused the convergence of these economies towards the productivity level of advanced market economies represented as EU15.
Accounting Measurement Rules in UK Bank Loan Contracts

Abstract This paper examines the financial ratio covenants found in a sample of 25 UK bank loan contracts and 13 contract templates. Minimum net worth, interest cover and gearing are the most widely occurring ratios. GAAP are used as the basis for all definitions. The definitions of net worth, borrowings and interest are frequently modified in a conservative direction, drawing on information both from the notes to published accounts and from outside those accounts. The definitions of profit, current assets and current liabilities, however, rarely deviate from GAAP. Thus some definitions restrict corporate management's scope to avoid covenant violation through appropriate accounting method choice while other definitions appear to permit it. Furthermore the widespread use of ‘rolling’ GAAP means that standard setters need to bear in mind that new standards can cause covenant violations. The findings of this study are consistent with those of previous research in the US and Australia.
A Neuroimmune Model of Gulf War Illness

Several studies have implicated immune system disruption in the pathophysiology of GWI. In addition, alterations in brain structure and functioning have been associated with specific exposures in theater, including pyridostigmine bromide and nerve gas agents. Recent studies conducted up to 25 years after the 1991 conflict have examined factors associated with the continuation or worsening of GWI. Drawing upon published studies of neural and immune system abnormalities in veterans with GWI, this paper proposes a model of GWI that takes into account neurologic and immunologic pathways, neuroimmune mechanisms of disease pathophysiology, individual predisposition due to sex and genetic background, and comorbid factors including neurological conditions such as neuritis/neuralgia and epilepsy that may occur along a continuum with GWI. The proposed neuroimmune model of GWI is likely to be useful for designing new research studies, clarifying factors involved in the continuation or worsening of GWI, and identifying biomarker screening algorithms for the illness. The proposed model goes beyond previously proposed frameworks for GWI by taking into account potential differences in risk based upon female vs. male sex, time elapsed since exposure to neurotoxicants, duration and severity of illness, comorbid conditions, and genotype.
Neocortical Temporal FDG‐PET Hypometabolism Correlates with Temporal Lobe Atrophy in Hippocampal Sclerosis Associated with Microscopic Cortical Dysplasia

Summary: Purpose: Medically intractable temporal lobe epilepsy (TLE) due to hippocampal sclerosis (HS), with or without cortical dysplasia (CD), is associated with atrophy of the hippocampal formation and regional fluorodeoxyglucose positron‐emission tomography (FDG‐PET) hypometabolism. The relation between areas of functional and structural abnormalities is not well understood. We investigate the relation between FDG‐PET metabolism and temporal lobe (TL) and hippocampal atrophy in patients with histologically proven isolated HS and HS associated with CD.
Decreased parvalbumin mRNA levels in cerebellar Purkinje cells in autism

Recent neuropathology studies in human brains indicate that several areas of the prefrontal cortex have decreased numbers of parvalbumin interneurons or decreased parvalbumin expression in Autism Spectrum disorders (ASD) [Hashemi, Ariza, Rogers, Noctor, & Martinez‐Cerdeno, 2017; Zikopoulos & Barbas, ]. These data suggest that a deficit in parvalbumin may be a key neuropathology of ASD and contribute to altered GABAergic inhibition. However, it is unclear if a deficit in parvalbumin is a phenomenon that occurs in regions other than the cerebral cortex. The cerebellum is a major region where neuropathology was first detected in ASD over three decades ago [Bauman & Kemper, ]. In view of the documented association between parvalbumin‐expressing neurons and autism, the objective of the present study was to determine if parvalbumin gene expression is also altered in Purkinje neurons of the cerebellum. Radioisotopic in situ hybridization histochemistry was used on human tissue sections from control and ASD brains in order to detect and measure parvalbumin mRNA levels at the single cell level in Purkinje cells of Crus II of the lateral cerebellar hemispheres. Results indicate that parvalbumin mRNA levels are significantly lower in Purkinje cells in ASD compared to control brains. This decrease was not influenced by post‐mortem interval or age at death. This result indicates that decreased parvalbumin expression is a more widespread feature of ASD. We discuss how this decrease may be implicated in altered cerebellar output to the cerebral cortex and in key ASD symptoms.

Sustainable Supply Chain Management—Decision Making and Support: The SSCM Maturity Model and System

Supply chains are complex systems, and the decision making and support processes for the development and management of such multifaceted entities are quite challenging. In order to become sustainable, supply chains are well advised to improve their business processes continuously and strive for strategic as well as functional alignment between their member organizations. Current supply chain practices are often ad hoc and lack end-to-end support for the gradual transformation towards supply chain sustainability. This article specifies high-level decision-making stages of sustainable supply chain management (SSCM) and proposes a multi-layered SSCM maturity model. This proposed model leverages a roadmap for sustainable business transformation and is further developed using a sustainability modelling and reporting (SMART) system.
Financial Openness, Sudden Stops and Current Account Reversals

In this paper I use a panel data set to investigate the mechanics of sudden stops of capital inflows and current account reversals. I am particularly interested in four questions: (a) What is the relationship between sudden stops and current account reversals? (b) To what extent does financial openness affect the probability of a country being subject to a current account reversal? In other words, do restrictions on capital mobility reduce the probability of such occurrences? (C) Does openness -- both trade openness and financial openness -- play a role in determining the effect of current account reversals on economic performance (i.e. GDP growth)? And, (d) does the exchange rate regime affect the intensity with which reversals affect real activity? The empirical analysis shows that sudden stops and current account reversals have been closely related. The econometric analysis suggests that restricting capital mobility does not reduce the probability of experiencing a reversal. Current account reversals, in turn, have had a negative effect on real growth that goes beyond their direct effect on investment. The regression analysis indicates that the negative effects of current account reversals on growth will depend on the country's degree of trade openness: More open countries will suffer less in terms of lower growth relative to trend than countries with a lower degree of trade openness. On the other hand, the degree of financial openness does not appear to be related to the intensity with which reversals affect real economic performance. The empirical analysis also suggests that countries with more flexible exchange rate regimes are able to accommodate better shocks stemming from a reversal than countries with more rigid exchange rate regimes.
Moving to local control of woodland resources – Can CAMPFIRE go beyond the mega-fauna?

Devolution of authority over natural resource management is now well advanced for the mega-fauna in Zimbabwe, through the CAMPFIRE program. We ask whether models like CAMPFIRE can be applied to a broader spectrum of woodland resources. Problems in applying CAMPFIRE to woodland resources relate to a legal and policy framework that is not enabling to local management; weakened local institutional structures; a high degree of differentiation with respect to wood land resource use within communities; problems of defining resource user groups; and, the potentially low market value of woodland products. In identifying circumstances where CAMPFIRE may be applied successfully to woodland resources, economic, sociological, and ecological circumstances must be considered.
A Gene Regulatory Program for Meiotic Prophase in the Fetal Ovary

The chromosomal program of meiotic prophase, comprising events such as laying down of meiotic cohesins, synapsis between homologs, and homologous recombination, must be preceded and enabled by the regulated induction of meiotic prophase genes. This gene regulatory program is poorly understood, particularly in organisms with a segregated germline. We characterized the gene regulatory program of meiotic prophase as it occurs in the mouse fetal ovary. By profiling gene expression in the mouse fetal ovary in mutants with whole tissue and single-cell techniques, we identified 104 genes expressed specifically in pre-meiotic to pachytene germ cells. We characterized the regulation of these genes by 1) retinoic acid (RA), which induces meiosis, 2) Dazl, which is required for germ cell competence to respond to RA, and 3) Stra8, a downstream target of RA required for the chromosomal program of meiotic prophase. Initial induction of practically all identified meiotic prophase genes requires Dazl. In the presence of Dazl, RA induces at least two pathways: one Stra8-independent, and one Stra8-dependent. Genes vary in their induction by Stra8, spanning fully Stra8-independent, partially Stra8-independent, and fully Stra8-dependent. Thus, Stra8 regulates the entirety of the chromosomal program but plays a more nuanced role in governing the gene expression program. We propose that Stra8-independent gene expression enables the stockpiling of selected meiotic structural proteins prior to the commencement of the chromosomal program. Unexpectedly, we discovered that Stra8 is required for prompt down-regulation of itself and Rec8. Germ cells that have expressed and down-regulated Stra8 are refractory to further Stra8 expression. Negative feedback of Stra8, and subsequent resistance to further Stra8 expression, may ensure a single, restricted pulse of Stra8 expression. Collectively, our findings reveal a gene regulatory logic by which germ cells prepare for the chromosomal program of meiotic prophase, and ensure that it is induced only once.
The Inefficiency of Fiscal Policy in Attracting Foreign Direct Investment in Selected Arab Countries

This study examines the effect of fiscal policy on foreign direct investment in five Arab countries (Egypt, Jordan, Morocco, Oman, and Tunisia). The foreign direct investment is assumed to be functionally related to its lag, growth rate of real GDP, openness to international trade, and a vector of fiscal policy indexes (import duties, corporate profit taxes, government spending, and capital expenditure). The empirical results obtained by estimating different regression models reveal empirical evidence supporting the hypothesis that fiscal policy does not affect the foreign firms’ motives to invest abroad. The regression statistics turn out to be robust across the regression models estimated above. In light of the results obtained, the selected countries examined must review their existing fiscal policies to efficiently attract more foreign direct investment.
