Performance Evaluation of Indian Airline Industry: An Application of DEA

The airlines in our country are experiencing low fares, poor load factors, drop in premium travels, decline in cargo loads and low yields due to deteriorating market conditions. To tide over the situation, companies need to have clear game plan and management strategies to effect turnaround of the airlines. This can be achieved only if companies know their performance gap with the benchmarked airline. Present work is aimed at calculating the relative performances of different Indian domestic airline industry (total 11 in India) using DEA framework. Data Envelopment Analysis is used to construct performance indices on the basis of the multiple outputs which airlines produce and the multiple inputs which they utilize. The result is used to find which variables the managers have some control over and what the relative importance of each variable is that affecting performance. Data Envelopment Analysis (DEA) provides a clear answer to the airline manager's problem.
Determination and prediction of digestible and metabolizable energy concentrations in byproduct feed ingredients fed to growing pigs

Objective An experiment was conducted to determine digestible energy (DE) and metabolizable energy (ME) of different byproduct feed ingredients fed to growing pigs, and to generate prediction equations for the DE and ME in feed ingredients. Methods Twelve barrows with an initial mean body weight of 31.8 kg were individually housed in metabolism crates that were equipped with a feeder and a nipple drinker. A 12×10 incomplete Latin square design was employed with 12 dietary treatments, 10 periods, and 12 animals. A basal diet was prepared to mainly contain the corn and soybean meal (SBM). Eleven additional diets were formulated to contain 30% of each test ingredient. All diets contained the same proportion of corn:SBM ratio at 4.14:1. The difference procedure was used to calculate the DE and ME in experimental ingredients. The in vitro dry matter disappearance for each test ingredient was determined. Results The DE and ME values in the SBM sources were greater (p<0.05) than those in other ingredients except high-protein distillers dried grains. However, DE and ME values in tapioca distillers dried grains (TDDG) were the lowest (p<0.05). The most suitable regression equations for the DE and ME concentrations (kcal/kg on the dry matter [DM] basis) in the test ingredients were: DE = 5,528–(156×ash)–(32.4×neutral detergent fiber [NDF]) with root mean square error = 232, R2 = 0.958, and p<0.001; ME = 5,243–(153 ash)–(30.7×NDF) with root mean square error = 277, R2 = 0.936, and p<0.001. All independent variables are in % on the DM basis. Conclusion The energy concentrations were greater in the SBM sources and were the least in the TDDG. The ash and NDF concentrations can be used to estimate the energy concentrations in the byproducts from oil-extraction and distillation processes.
Weekly paclitaxel for platin-resistant stage IV head and neck cancer patients

Conclusions. Weekly paclitaxel may be an active and well tolerated chemotherapy regimen for patients with platin-resistant advanced head and neck cancer. Objectives. Weekly paclitaxel should be an active and well tolerated regimen for palliative treatment of platin-resistant patients with recurrent or metastatic carcinoma of the head and neck. We analyzed the antitumor activity and toxicity profile. Patients and methods. Sixty consecutive patients with advanced head and neck cancer were treated with 1 h infusion of paclitaxel, 80 mg/m2 weekly, for 6 consecutive weeks. Patients who showed disease response or disease stabilization continued until progression of disease. Results. A total of 719 doses of paclitaxel were administered to the 60 patients. No complete response was observed. Partial response and stable disease were observed in 26 (43.3%) and 9 (15%) patients, respectively. Median time to tumor progression for patients who responded to therapy was 6.2 months (SD=1.3; 95% CI, 3.7–8.6) and the overall median survival in this group of patients was 8.5 months (SD=1.4; 95% CI, 5.7–11.2). The main toxic effects were leukopenia (26.6%), anemia (43.3%), fatigue (37.4%), alopecia (18.7%), rash/desquamation (13.3%), and thrombophlebitis (6.8%).
Dielectric function and local-field effects of TiSe2.

The dielectric function (DF) for this prototype of the layered dichalcogenides has been determined on the basis of two different procedures. The first uses an ab initio method, the extended linearized augmented plane wave (LAPW) scheme, to calculate the microscopic DF, \ensuremath{\epsilon}(0,0;\ensuremath{\omega}). The second relies on an empirical tight-binding fit to yield the \ensuremath{\epsilon}(q+G,q+G';\ensuremath{\omega}), and the macroscopic DF via the inverse dielectric matrix. The former is especially suited for discussing the optical spectra whereas the latter accounts for the local-field effects near the plasma frequency. The results are compared with experimental reflectivity and ellipsometric data.
The promoter of Alzheimer's disease amyloid A4 precursor gene.

The promoter of the gene for the human precursor of Alzheimer's disease A4 amyloid protein (PAD gene) resembles promoters of housekeeping genes. It lacks a typical TATA box and shows a high GC content of 72% in a DNA region that confers promoter activity to a reporter gene in an in vivo assay. Transcription initiates at multiple sites. Sequences homologous to the consensus binding sites of transcription factor AP‐1 and the heat shock control element binding protein were found upstream of the RNA start sites. Six copies of a 9‐bp‐long GC‐rich element are located between positions −200 and −100. A protein–DNA interaction could be mapped to this element. The 3.8 kb of the 5′ region of the PAD gene include two Alu‐type repetitive sequences. These findings suggest that four mechanisms may participate in the regulation of the PAD gene and could be of relevance for the progression of amyloid deposition in Alzheimer's disease.
Quantifier Guided Aggregation for the Veracity Assessment of Online Reviews

The Social Web is characterized by a massive diffusion of unfiltered content, directly generated by users via the spread of different social media platforms. In this context, a challenging issue is to assess the veracity of the information generated within the sites of online reviews. To address this issue, a common practice in the literature is to select and analyze some veracity features associated with users and their reviews, by mostly applying machine learning techniques, to provide a classification in genuine and deceptive reviews. In this paper, we do not focus on the feature selection and user behavior analysis issues, but we concentrate on the aggregation process with respect to each single veracity feature. In most of the approaches based on machine learning techniques, the contribution of each feature in the classification process is not measurable by the user. For this reason, we propose a multicriteria decision making approach based both on the assessment of multiple criteria and the use of aggregation operators with the aim of obtaining a veracity score associated with each review. Based on this score, it is possible to detect fake reviews. The proposed model is evaluated on a Yelp data set by applying different aggregation schemes, and it is compared with well‐known supervised machine learning techniques.
Diversity and Distribution of Planctomycetes and Related Bacteria in the Suboxic Zone of the Black Sea

ABSTRACT Samples from six depths of the Black Sea's suboxic zone were analyzed for 16S rRNA gene sequence information. A gradient in phylotype diversity was found. The distributions of known anaerobic ammonium oxidation (anammox) bacteria, many unknown Planctomycetes, and other phylotypes were examined in relation to the local nutrient and redox conditions.
Organisational culture in the public sector: evidence from six organisations

A process of organisational change has accompanied managerial reforms in the public sector and is oriented towards the development of a post‐bureaucratic organisational culture. However, there remains a limited empirical understanding of culture in public organisations. Contributes to an understanding of organisational culture in the public sector through survey research that analyses culture by reference to the competing values of internal/external orientation and control/flexibility. Focuses on six organisations in the Queensland public sector which have been encouraged to depart from traditional bureaucratic values and to adopt a greater emphasis on change, flexibility, entrepreneurialism, outcomes, efficiency and productivity. Suggests, however, that public sector organisations continue to emphasise the values of a bureaucratic or hierarchical organisational culture.
Can CEO Dismissals Be Proactive?

We find significant variation in the prior stock returns of firms that dismiss their CEOs between 1996 and 2008. 49% of firms that dismiss their CEOs do so in the absence of negative industry-adjusted stock returns prior to dismissal (37% dismiss in the absence of negative raw returns). We find evidence for two reasons why boards may dismiss CEOs early, i.e., in the absence of significant poor prior stock performance. First, we find that early dismissals are more likely to be associated with corporate scandals, suggesting that CEOs that are found to engage in unethical or illegal activities are dismissed although their actions may not have a significant adverse impact on firm value. Second, we find support for the argument that early dismissals are proactive actions by boards to dismiss low ability CEOs. We find that firms with more equity-based compensation for directors and higher independent director ownership are more likely to dismiss their CEOs early. Boards with strong incentives are more likely to be proactive and act on their private information about the CEO than boards with poor incentives. Early dismissal firms experience a short-lived decline in operating performance around the date of CEO dismissal, and their operating performance recovers immediately after the CEO is replaced. On the other hand, the operating performance of late dismissal firms declines significantly prior to dismissal and improves substantially after dismissal. We also find that CEOs that are dismissed early are not more likely to find new CEO positions than CEOs that are dismissed late, supporting the idea that early dismissal CEOs may not have different ability than late dismissal CEOs.
The Employment Guarantee Scheme in India Is It Mistargeted

The Employment Guarantee Scheme (EGS) in the Indian state of Maharashtra is widely regarded as a most successful anti-poverty intervention. Its success has prompted similar interventions elsewhere. A variant, the Employment Assurance Scheme (EAS), for example, has just been launched on a large scale in some of the most backward regions in India. ' But contrary to a widely held view, a survey by the International Crops Research Institute for the Semi-Arid Tropics (ICRIST) shows that the EGS in Maharashtra was mistargeted, and that the targeting worsened over the years with the more affluent capturing a larger share of EGS earnings. Analyzing the survey data, this article finds that overall benefits to the rural poor were far from negligible and concludes that the scheme cannot be dismissed out of hand.
Effect of intravenous glucose and euglycemic insulin infusions on short-term appetite and food intake.

To investigate the short-term effects of insulin on feeding, 14 fasting, young adults received 150-min euglycemic intravenous infusions of control (C), low-dose (LD, 0.8 mU.kg-1.min-1), and high-dose (HD, 1.6 mU.kg-1.min-1) insulin and ate freely from a buffet meal during the last 30 min. Steady-state preprandial plasma insulin concentrations were 5.9 +/- 0.7 (C), 47 +/- 2 (LD), and 95 +/- 6 (HD) microU/ml and increased 56-59 microU/ml during the meal. No effect of treatment type of hunger or fullness ratings, duration of eating, or the weight, energy content (1,053 +/- 95 kcal, C; 1,045 +/- 101 kcal, LD; 1,066 +/- 107 kcal, HD; P = 0.9), and composition of food eaten was observed. On a fourth study day, 12 of the subjects received an intravenous infusion of glucose only (Glc) that was identical to the glucose infusion on their HD insulin day. Mean venous glucose concentration was 9.3 +/- 0.5 mmol [P < 0.001 vs. C (5.3 +/- 0.1), LD (5.2 +/- 0.2), and HD (5.2 +/- 0.2)], and plasma insulin increased to 45 +/- 2.3 microU/ml at the start and 242 +/- 36 microU/ml at the end of the meal. Energy intake during the meal was (approximately 15%) reduced (1,072 +/- 97 kcal, C; 1,086 +/- 102 kcal, LD; 1,088 +/- 105 kcal, HD; 919 +/- 115 kcal, Glc; P < 0.05 Glc vs. C, LD, and HD). Plasma insulin normally increases to approximately 100 microU/ml after a mixed meal in lean subjects. Therefore, in the absence of altered blood glucose concentrations, physiological concentrations of insulin are unlikely to play a role in meal termination and the short-term control of appetite.
A new algorithm for fault location on transmission lines

In this paper, a new algorithm for fault detection/location on transmission line based on linear state estimation is presented. The proposed technique uses phasor measurements from PMU's. Fault location and voltage of fault point are added as the new state variables in a linear state estimator based on PMU data. In addition, by using the ability of bad data identification in the state estimation, a new scheme for fault location and identification of faulted transmission line is proposed. For test and validation of the proposed algorithm, simulation results on a six bus test case are presented.
Moral judgment and decision making under uncertainty

From virtue theory to moral psychology to behavioral economics, a range of disciplines have explained behavior in moral situations by states of the individual mind, such as character traits, moral stages, or social preferences. These internal explanations predict that moral behavior is stable across a range of situations and thus struggle with the common observation of inconsistencies in moral judgment and behavior. In contrast, we first outline how the same heuristic predicts systematically different outcomes, ethical or unethical, depending on differences in the environment. Behavior that appears inconsistent from an internal point of view is actually consistent when the interaction between heuristics and social environments is taken in consideration. Second, we argue that the heuristics determining much of judgment and behavior in moral situations are not specifically moral rules, but morally neutral heuristics that serve particular social goals. Specifying these processes can facilitate understanding when and why humans succeed or fail in pursuing ethical goals. The approach thus emphasizes the relevance of designing better environments, not just better people, in order to effectively promote the ethical goals valued by a society.
Can CDO Equity Be Short on Correlation?

Collateralized debt obligations (CDO) became very popular investment vehicles in recent years—until the financial crisis started unfolding in summer 2007. As evidenced by the recent crisis, there was a failure by market participants to understand the complex relationships between various risk drivers, such as correlations and their impact on the credit worthiness of different tranches across a CDO capital structure. As a step in the direction of understanding these risks, this article examines the impact of correlation on the value of a CDO equity tranche. By examining the impact of an increase in correlation among underlying assets on the value of a collateralized debt obligation (CDO) equity tranche, the authors show that, contrary to general perception, CDO equity can be short on correlation. Specifically, when the underlying reference portfolio comprises high quality assets (assets with low probability of default) or diverse assets (assets with low correlations), the upfront price of a CDO equity tranche can increase with correlation. The implication of these findings is that not all senior and equity tranche trade combinations provide effective correlation hedging. In fact, in some cases, this type of “hedge” might actually increase the correlation risk.
Bottleneck Identification Techniques Leading to Simplified Performance Models for Efficient Design Space Exploration in VLSI Memory Systems

High performance VLSI systems are being built as multi-processor systems-on-chip. The number of processors and their performance is rising rapidly while the change is slower for the memories. The memory system is often a performance bottleneck in terms of either its bandwidth or latency. We propose sensitivity analysis as a means to pin-point the bottleneck. We introduce a novel randomized technique to measure the sensitivities within cycle accurate simulators. The sensitivity measures identify the bottleneck regions of the design space, within which simplified performance models can be used for optimization. We demonstrate this methodology on the Augmint-MemSim simulator, which is a cycle accurate model for multi-processor systems with a distributed memory sub-system. We empirically show that: (i) Performance predictions from simplified models are strongly correlated with the simulator in the high sensitivity regions. (ii) The simplified models speed up design space exploration by 2 - 3 orders of magnitude over the simulator resulting in better design solutions.
THE EFFECTIVE DOSE EQUIVALENT AND EFFECTIVE DOSE FOR HOT PARTICLES ON THE SKIN

Whole body exposure from photon-emitting hot particles is a relatively new problem. Until recently, the U.S. Nuclear Regulatory Commission required the use of deep dose equivalent (DDE) to estimate and report whole body exposures from hot particles. In this study, effective dose equivalent (EDE) and effective dose (ED) were calculated for point sources with photon energies between 0.1 MeV to 2.0 MeV for 74 locations covering the entire body surface, using the MCNP code and the MIRD-type stylized phantoms. Tabulated data show that the sources located near the upper chest and the lower waist have the highest EDE and ED, while sources near the top of head and feet yielded the smallest. The calculated DDE values are much higher than the EDE values. For an exposure of 75 &mgr;Ci h−1 to a 60Co source located at the center upper chest area, the EDE is 36.5 &mgr;Sv (3.65 mrem), which is a factor of 240 smaller than the corresponding DDE. EDE and ED data are tabulated for quick reference by users in nuclear power plants.

A model for designing of decision support system is a simulation that induces reality and uses di ↵ erent models to describe the complex reality. It also concerns uncertainty and can help users to achieve a conceptual and detailed description of the reality. Serious game is being used as a tool for developing model for a long time. Producing serious games simulation environments is one of the best options in data collection, trial and error, and learning and decision-making for the investment markets that rapid change of the rate increases the risk. A virtual system will provide better aid by using actual data foe a better management of the ﬁnancial resources and o ↵ er options for users at every level of decision. Entering the stock market is possible for everyone but the possibility of selecting a stock portfolio that results in achieving a good proﬁt is very di � cult and hard, due to rapidly changing customer markets is becoming more di � cult. That is it’s a high-risk environment for investors. Indeed people do not have su � cient experience and training in this ﬁeld. The aim
Split‐Award Procurement Auctions—Can Bayesian Equilibrium Strategies Predict Human Bidding Behavior in Multi‐Object Auctions?

We analyze if and when symmetric Bayes Nash equilibrium predictions can explain human bidding behavior in multi‐object auctions. We focus on two sealed‐bid split‐award auctions with ex ante split decisions as they can be regularly found in procurement practice. These auction formats are straightforward multi‐object extensions of the first‐price sealed‐bid auction. We derive the risk‐neutral symmetric Bayes Nash equilibrium strategies and find that, although the two auction mechanisms yield the same expected costs to the buyer, other aspects of the two models, including the equilibrium bidding strategies, differ significantly. The strategic considerations in these auction formats are more involved than in single‐lot first‐price sealed‐bid auctions, and it is questionable whether expected utility maximization can explain human bidding behavior in such multi‐object auctions. Therefore, we analyzed the predictive accuracy of our equilibrium strategies in the laboratory. In human subject experiments we found underbidding, which is in line with earlier experiments on single‐lot first‐price sealed‐bid auctions. To control for regret, we organize experiments against computerized bidders, who play the equilibrium strategy. In computerized experiments where bid functions are only used in a single auction, we found significant underbidding on low‐cost draws. In experiments where the bid function is reused in 100 auctions, we could also control effectively for risk aversion, and there is no significant difference of the average bidding behavior and the risk‐neutral Bayes Nash equilibrium bid function. The results suggest that strategic complexity does not serve as an explanation for underbidding in split‐award procurement auctions, but risk aversion does have a significant impact.
Reliability of the Radiological Assessments of Radiolucency and Loosening in Total Hip Arthroplasty Using Pacs

We evaluated the reliability of three commonly used radiological assessments of total hip arthroplasty (THA) using the electronic picture archiving and communications system (PACS). Thirty-three patients were selected at random at a mean of 7.2 years after THA. The Barrack, Gruen and Hodgkinson evaluations of cementing quality, loosening/radiolucency were graded. Three observers assessed each radiograph (one consultant orthopaedic surgeon, one senior orthopaedic registrar and one senior house officer). Four weeks after the initial assessment, each radiograph was reviewed a second time. The findings indicated that the intra- and inter-observer reliability of the Barrack, Gruen and Hodgkinson methods were questionable. Inter-observer reliability using the Gruen system was poor, using the Barrack system it was moderate to good, and fair to good using the Hodgkinson assessment. Intra-observer reliability was moderate to good for Barrack assessment, poor to good using Gruen zone assessments, but good to very good for the Hodgkinson assessment. The use of Barrack, Gruen and Hodgkinson assessments to evaluate femoral and acetabular loosening should be questioned since these exhibit limited inter- and intra-observer reliability on PACS radiographs, but of the three, the Hodgkinson system is the most reliable.
