Survey on High Utility Itemset Mining from Large Transaction Databases

Data mining can be defined as an activity that extracts some knowledge contained in large transaction databases. Conventional data mining techniques have focused largely on finding the items that are more frequent in the transaction databases, which is also called frequent itemset mining. These data mining techniques were based on supportconfidence model. Itemsets which appear more frequently in the database must be of more meaning to the user from the business point of view. In this paper we present an emerging area called as High Utility Itemset Mining that discovers the itemsets considering not only the frequency of the itemset but also utility associated with the itemset. Every itemset have a value like quantity, profit and other user’s interest. This value associated with every item in a database is called the utility of that itemset. Those itemsets having utility values greater than given threshold are called high utility itemsets. This problem can be identified as mining high utility itemsets from transaction database. In many areas of business like retail, inventory etc. decision making is very important. So it can help in mining algorithm, the presence of each item in a transaction database is represented by a binary value, without considering its quantity or an associated weight such as price or profit. However quantity, profit and weight of an itemset are significant for identifying real world decision problems that require increasing the utility in an organization. Mining high utility itemsets from transaction database presents a greater challenge as compared with frequent itemset mining, since anti-monotone property of frequent itemsets is not applicable in high utility itemsets. In this paper, we present a survey on the current state of research and the various algorithms and techniques for high utility itemset mining.

Impact of the using non-regular employees on On-the-job training: from both viewpoints of companies and workers

Based on previous studies which clarified that employment of non-regular employees has a negative impact on firm-level training, this paper verified whether it is caused by quantitative change in non-regular employees or functional problems such as employment policy of non-regular employees. As a result of the analysis, it was confirmed that quantitative increase in non-regular employees is not a major impediment to implementation of On-the-Job Training (OJT). On the other hand, it was confirmed that OJT does not function smoothly in companies where the number of regular employees’ employment is reduced by the employment of non-regular employees. This indicates that OJT is not functioning smoothly in companies in which regular employees have been replaced with non-regular ones. It indicated a possibility that the impact of employment of non-regular employees on OJT is caused by a functional problem of human resources management, i.e., using non-regular employees as substitutes for regular employees, not quantitative change in non-regular employees.
Passive Harmonic Mode-Locking of Dissipative Solitons in a Normal-Dispersion Er-Doped Fiber Laser

Tunable harmonic mode-locking of (HML) one kind of dissipative solitons (DSs) has been experimentally demonstrated in an Er-doped fiber (EDF) laser for the first time. The laser is mode-locked by nonlinear polarization rotation. The repetition rate can be tuned from the 2nd to 10th-order HML. A high repetition rate of 232 MHz (10th- order HML) has been observed in this laser, and the pulse duration after compression is 153-fs with single-pulse energy of 0.5 nJ. The spectral width of the pulses decreases as the harmonic order increases in the experiment, which is demonstrated for the first time, consistent with the numerical study. A rule based on monitoring the pulse spectral width to find desired-order HML is also proposed.
Micro-particle transport manipulation by guided-wave optical interference

In this paper, we demonstrate that micro-particle is able to be transported by two types of integrated photonic devices; one is directional couplers and the other is multimode interferometers. Micro-particles are propelled by the evanescent wave and guided by the interference pattern of optical field inside the devices. By properly designing the device length and operation wavelength, micro-particles can be switched to either one of the output ports connecting the devices.
The Yaf9 Component of the SWR1 and NuA4 Complexes Is Required for Proper Gene Expression, Histone H4 Acetylation, and Htz1 Replacement near Telomeres

ABSTRACT Yaf9, Taf14, and Sas5 comprise the YEATS domain family in Saccharomyces cerevisiae, which in humans includes proteins involved in acute leukemias. The YEATS domain family is essential, as a yaf9Δ taf14Δ sas5Δ triple mutant is nonviable. We verify that Yaf9 is a stable component of NuA4, an essential histone H4 acetyltransferase complex. Yaf9 is also associated with the SWR1 complex, which deposits the histone H2A variant Htz1. However, the functional contribution of Yaf9 to these complexes has not been determined. Strains lacking YAF9 are sensitive to DNA-damaging agents, cold, and caffeine, and the YEATS domain is required for full Yaf9 function. NuA4 lacking Yaf9 retains histone acetyltransferase activity in vitro, and Yaf9 does not markedly reduce bulk H4 acetylation levels, suggesting a role for Yaf9 in the targeting or regulation of NuA4. Interestingly, yaf9Δ strains display reduced transcription of genes near certain telomeres, and their repression is correlated with reduced H4 acetylation, reduced occupancy by Htz1, and increased occupancy by the silencing protein Sir3. Additionally, the spectra of phenotypes, genes, and telomeres affected in yaf9Δ and htz1Δ strains are significantly similar, further supporting a role for Yaf9 in Htz1 deposition. Taken together, these data indicate that Yaf9 may function in NuA4 and SWR1 complexes to help antagonize silencing near telomeres.
Efficiency and Productivity Performance of the National Private Banks in Indonesia

This study investigates the efficiency and productivity performance of the national private banks in Indonesia during the period of 2002-2004. The data consist of 21 national private banks including two Islamic banks. Productivity is measured by the Malmquist Index using Data Envelopment Analysis (DEA) technique. Overall, the result shows that the Total Factor Production (TFP) Index of the national private banks has considerably increased for the whole industry, in which technical change is found to be a more important source of productivity growth to the Indonesian Banking Industry compared to efficiency change. Furthermore, the result also shows that the efficiency of two Islamic banks is above the average efficiency of the national private banks.
Children's Search for Gender Cues

Young children search for cues about gender—who should or should not do a particular activity, who can play with whom, and why girls and boys are different. From a vast array of gendered cues in their social worlds, children quickly form an impressive constellation of gender cognitions, including gender self-conceptions (gender identity) and gender stereotypes. Cognitive perspectives on gender development (i.e., cognitive developmental theory and gender-schema theory) assume that children actively search for ways to make sense of the social world that surrounds them. Gender identity develops as children realize that they belong to one gender group, and the consequences include increased motivation to be similar to other members of their group, preferences for members of their own group, selective attention to and memory for information relevant to their own sex, and increased interest in activities relevant to their own sex. Cognitive perspectives have been influential in increasing understanding of how children develop and apply gender stereotypes, and in their focus on children's active role in gender socialization.
RFID Tag Reading Effects of Cylindrical Conductive Packages

We study two classes of passive UHF RFID tag antennas: bowties and slots, on conductive cylinders. We find better performance can be achieved when the tag is cross-polarized with the main axis of cylindrical containers. The performance degradation under co-polarization can be attributed to the reduction of radiation efficiency and the detuning of antenna impedance due to the stronger scattering interference from the metallic package. Our results serve as a general guideline to determine the right tag orientation for reliable readability
Risk Management Capability within Malaysian Food Supply Chains

This paper presents a literature review of the issues surrounding supply chain risk management within the Malaysian food industry and identifies key risk management techniques used by the food industry. With reference to the recent cases of food contamination, food safety has gained increased focus once again and various government agencies around the globe have been involved in monitoring food safety practices in their respective countries. Although there are consultancy reports available with respect to managing food supply chain risks, there is limited academic literature with respect to research conducted on managing food supply chain risks. Hence, this paper tries to explore how supply chain risks are managed within the Malaysian food supply chains. Also, the paper presents the results from a pilot survey. The survey was conducted in an effort to explore further the understanding and perceptions that entities within the Malaysian food supply chains have regarding supply chain risks and the techniques deployed to mitigate and manage risks and disruptions. The results of the survey is related to specific food supply chain and not be generic of all food supply chains. This pilot study can provide some good insight for conducting a bigger survey with a larger sample size in the future.
An Econometric Analysis for the Behavior of the Bid-Ask Spread

Information asymmetries are an important element in the functioning of capital markets. An indirect means of measuring information asymmetry is through the spread of stock prices. The purpose of this paper is to identify the explanatory variables and the determinants of the bid-ask spread and to quantify the influence that the actors involved in the brokering of publically offered securities may have over the spread. The methodology used to model the time series for each of the analyzed companies is based on a time series from each of the observed econometric multivariate processes. The analysis shows a significantly negative relationship between the spread and the market-maker size, calculated in terms of both the equity and the stock portfolio; likewise, activity is measured by observing the amount offered for purchase and/or sale.
Nonconsolidated subsidiaries, bank capitalization and risk taking

Bank holding companies may be effectively undercapitalized as a result of incomplete consolidation of minority ownership. Using two approaches -- consolidating the minority-owned subsidiaries into the parent or deducting equity investments in minority ownership from the parent’s capital -- we find that the effective capital ratios of US bank holding companies are substantially lower than the reported ratios. Empirical evidence suggests that the undercapitalization is associated with higher risk taking at the bank holding company level. These findings indicate that incomplete consolidation of minority-owned financial institutions constitutes a loophole in capital regulation.
Pension information, financial literacy, and retirement saving behaviour in Germany

In Germany, the 2001 pension reform caused a shift from the monolithic pension system based on the statutory public pension scheme with a constant pension level safeguarding the standards of living in old age towards a multi-pillar system. This multi-pillar approach also shifted the responsibility for old-age income from the state towards individuals. In the wake of the reform, policy makers realized that the provision of transparent and comparable information on rights accrued within the first pillar deemed crucial as a basis for workers' decision about joining an additional occupational or private pension. For this reason, the German pension authority implemented an annual pension information statement in 2004. About 10 years after the introduction the German population is aware of the annual pension information statement. Nonetheless, the evaluation of different pieces of information varies. The forecast of the individual amount of regular old-age and invalidity pension are regarded most useful. Information hedged in a block of text is less often regarded useful or not read at all. In general, the information provided causes non changes in savings behaviour.
Customer satisfaction and profitability: is there a lagged effect?

Although customer satisfaction is one of the fundamental concepts in marketing theory and practices, the direct link between customer satisfaction and a firm's bottom line is still somewhat ambiguous and vague. While most research focuses on how customer satisfaction contributes to the firm's profitability, financial resources required to implement satisfaction programs are largely ignored in the literature. This paper takes a conceptual middle ground, proposing that customer satisfaction influences profitability, and at the same time, profitability impacts satisfaction. However, based on recent evidence (Rust, Moorman and Dickson, 2002), we propose that there is a lagged effect between the two. In other words, past satisfaction has a positive effect on current profitability, and similarly, past profitability affects current satisfaction. Furthermore, event study methodology is utilized to examine stock reaction to the announcement of the firm's satisfaction performance, solidifying the relationship between satisfaction, a marketing metric, and financial performance.
Fluvastatin Normalizes The Decreased Turnovers Of Glutathione And Ascorbic Acid In Watanabe Heritable Hyperlipidaemic Rabbits

1. Fluvastatin, a 3‐hydroxy‐3‐methylglutaryl coenzyme A reductase inhibitor, has been reported to decrease the oxidizability of plasma lipids in hyperlipidaemic subjects. In order to elucidate one of the mechanisms of this in vivo, we investigated the effects of fluvastatin and pravastatin on the decreased turnovers of reduced glutathione (GSH) and ascorbic acid (AA) in Watanabe heritable hyperlipidaemic (WHHL) rabbits.
Global convergence of phase retrieval by quadratic approach

The reliability of two different implementations of a quadratic phase retrieval approach to the problem of determining the far field of a radiating system from only square amplitude information on the near field zone is studied. The first implementation exploits square amplitude data over two scanning surfaces. The second one exploits the square amplitude of the voltages received by two different probes moving over a single scanning surface. It is pointed out how the diversity between the two scanning surface data or the two probes gives rise to "cancellation effects" which help in avoiding the local minima problem. Numerical examples are shown to discuss the global convergence properties of the two algorithms.
Correlation of clinical and MRI staging in cervical carcinoma treated with radiation therapy: a single-center experience.

PURPOSE To correlate clinical and MRI findings in patients with cervical carcinoma treated with radiation therapy (RT). MATERIALS AND METHODS Forty-two patients with pretreatment IB-IVA cervical carcinoma were included in this retrospective study. Pre- and post-treatment MRI findings of the patients were reevaluated and compared with clinical staging. Six-month, one-year, and two-year follow-up imaging by MR was performed for 36, 20, and 7 patients, respectively. The correlation between clinical and MRI findings was assessed by a Spearman's rho (rank correlation) test. Univariate analyses were performed to identify the prognostic significance of the tumor volume and lymph node status. RESULTS Pre-treatment correlations between MRI and clinical findings for diagnoses without parametrial invasion, with parametrial invasion, and with pelvic sidewall invasion were 71.0%, 64.7%, and 15.8%, respectively. According to the Spearman's rho (rank correlation) test, the parametrial invasion correlation was poor (r = 0.410, P < 0.01). The correlation of clinical and MRI findings at 6 months was 88.9% (r = 0.674, P < 0.0001). CONCLUSION In advanced cervical cancer, the correlation of clinical and MRI staging prior to neoadjuvant RT was low despite a high correspondence in the assessment of local response after RT.
Effect of exclusive enteral nutrition on gut microflora function in children with Crohn's disease

Abstract Objective. Exclusive enteral nutrition (EEN) is a first-line treatment in children with active Crohn's disease (CD) but is seldom used in adults with active disease. The mode of action of EEN in suppressing mucosal inflammation is not fully understood, but modulation of intestinal microflora activity is one possible explanation. The aim of this study was to investigate the effect of 6-week EEN in children with active CD, with special reference to intestinal microflora function. Materials and methods. Fecal samples from 18 children (11 boys, 7 girls; median age 13.5 years) with active CD (13 children with small bowel/colonic and 5 with perianal disease) were analyzed for short chain fatty acid (SCFA) pattern as marker of gut microflora function. The children were studied before and after EEN treatment. Results from 12 healthy teenagers were used for comparison. Results. Eleven (79%) of the children with small bowel/colonic CD responded clinically positively to EEN treatment showing decreased levels of pro-inflammatory acetic acid as well as increased concentrations of anti-inflammatory butyric acids and also of valeric acids, similar to the levels in healthy age-matched children. In children with active perianal CD, however, EEN had no positive effect on clinical status or inflammatory parameters. Conclusions. The authors present new data supporting the hypothesis that the well-documented anti-inflammatory effect of EEN in children with active small bowel/colonic CD is brought about by modulation of gut microflora activity, resulting in an anti-inflammatory SCFA pattern. By contrast, none of the children with perianal disease showed clinical or biochemical improvement after EEN treatment.
Rb protein dynamic modeling

Cancer is the second cause of death in developed countries after cardiovascular diseases. Our work serves in a better understanding of pRb-E2F process, a significant pathway of the cell cycle control and a frequent target of mutational events in the most human cancers. Using a mathematical model, the simulated phenomena that characterize the real system, preserves the logical structure, allowing to obtain information on process status at different moments of time.
JOB RESOURCES, EMPLOYEES' CREATIVITY AND FIRM PERFORMANCE OF COMMERCIAL BANKS IN UGANDA

This study was intended to examine the relationship between job resources, employees’ creativity and firm performance of commercial banks in Uganda. It was motivated by the poor performance of some commercial banks in Uganda, the scantiness of studies about the link between job resources, employees’ creativity and firm performance of commercial banks in Uganda as well as calls from previous scholars for more research. A quantitative and cross sectional research designs were employed for this study. Data were collected using selfadministered questionnaires from commercial banks. We performed a Pearson correlation and multiple regressions when analyzing data. The study posts a positive relationship between Job resources, Employee Creativity and Firm performance in Uganda. Findings show that 29% of the change in commercial bank’s performance is explained by job resources and employee creativity. The study focuses on job resources and employee creativity, concepts that are not very well appreciated and only understood as humanitarian and not actually viewed as a means to improve commercial bank’s performance in Uganda. The significance of this paper is to contribute to the scarcity of literature on the Ugandan experience concerning Job resources, Employee creativity and Firm performance.
Micro CT study of soft/elastic structures of beetle toward insect-inspired robotics

We propose a new framework for making insect-inspired robots using micro-focus X-ray computed tomography (micro CT). Micro CT system used in this study is originally for non-invasive inspection for industrial and medical applications, not for robotics. The CT data provides three-dimensional information of the complex structure of animal body in micrometer resolution. We shoot CT images of rhinoceros beetles (Trypoxy-lus dichotomus) to reveal its musculoskeletal system, flapping mechanism, wing veins, and multi-segment limbs. The cross sectional images enables to identify the flight muscles and joint mechanism. Moreover, three-dimensional reconstruction of CT data allows replicating insect body with additive manufacturing technique. We used multi-material 3D printer for printing a wing vein and a shell from the volumetric data. The results shows that the 3D printed artificial shell can reproduce the linkage mechanism of flapping motion. Micro CT studies of insects enhance a further understanding of biological systems and development of bio-inspired robots.
