A Fusion Model for Stock selection Based on Decision Tree, Artificial Neural Network and Grey Relational Analysis

In this study, the Decision Tree is combined with Artificial Neural Network and Grey Relational Analysis to create an automatic stock selection mechanism. In the proposed approach, this fusion model contains three steps. The first step was to evaluate the influence of the input variables (financial ratios) on the output variables (financial structure)from the component stocks of MSCI Taiwan index and stocks requiring full delivery with sensitivity approach of Artificial Neural Networks)in order to select critical financial ratio for training of Decision Tree. The second step was to build up the standard procedure of selecting stocks with Return On Equity and the principles from the training of Decision Tree. Finally, the rank of selecting stocks with Grey Relational Analysis has been adopted for portfolio use. All Taiwan listed companies from November 30, 2008 to April 8, 2013 were taken for empirical test. The annual rate of return of our portfolio was 89%. It defeated the rate of return of the similar Mutual Funds established in 2012. It is found that the proposed method could not only keep the effect of all attributes and reduce the number of inputs in a complicated system, but also yields a great rate of return on the selected stocks.
Attacking the tav-128 hash function

Many RFID protocols use cryptographic hash functions for their security. The resource constrained nature of RFID systems forces the use of light weight cryptographic algorithms. Tav-128 is one such light weight hash function proposed by Peris-Lopez et al. for an RFID authentication protocol. In this article we show that Tav-128 is not collision resistant. We show a practical collision attack against Tav-128 and produce message pairs of arbitrary length which produce the same hash value under this hash function. We also study the constituent functions of Tav-128 and show that the concatenation of nonlinear functions A and B produces a 64-bit permutation from 32-bit messages. This could be a useful light weight primitive for future RFID protocols.
Conjugal transfer of broad-host-range incompatibility group P and Q plasmids from Escherichia coli to Actinobacillus actinomycetemcomitans

The first example of conjugal transfer of DNA from Escherichia coli to the periodontal pathogen Actinobacillus actinomycetemcomitans is presented. Derivatives of the incompatibility group P (IncP) plasmid RK2 successfully transferred from an E. coli donor to an A. actinomycetemcomitans recipient. The resulting A. actinomycetemcomitans transconjugants transferred the plasmids back to E. coli recipients. The IncP transfer functions were also used in trans to mobilize the IncQ plasmid pBK1 from E. coli to A. actinomycetemcomitans. The IncP and IncQ plasmids both transferred into A. actinomycetemcomitans at high frequencies (0.3 to 0.5 transconjugants per donor) and showed no gross deletions, insertions, or rearrangements. Determinations of MICs of various antibiotics for the A. actinomycetemcomitans transconjugant strains demonstrated the expression of ampicillin, chloramphenicol, and kanamycin resistance determinants.
Coping Self-Efficacy Moderates the Association Between Severity of Partner Violence and PTSD Symptoms Among Incarcerated Women.

Previous research indicates self-efficacy may function as a protective factor for survivors of partner violence (PV), including coping self-efficacy specific to domestic violence. We hypothesized that domestic violence coping self-efficacy would moderate the association between recent PV and posttraumatic stress disorder (PTSD) symptoms in a sample of incarcerated women, such that the association between PV and PTSD would be strongest at low levels of domestic violence coping self-efficacy. Participants (N = 102) were incarcerated women who reported PV in the year prior to incarceration. They were aged 19-55 years (M = 33.57, SD = 9.32), identified predominantly as European American (84.3%), American Indian (15.7%), and Hispanic (14.7%), with 80.4% completing high school or more in terms of education. Participants responded to self-report measures of PV, trauma history, domestic violence coping self-efficacy, and current PTSD symptoms. In a series of sequential regression analyses, PV (β = .65, sr(2) = . 06, p = . 017) was significantly associated with current PTSD symptoms above and beyond past trauma history (β = .37, sr(2) = . 14, p < . 001), and this association was moderated by domestic violence coping self-efficacy (Domestic Violence Coping Self-Efficacy × Partner Violence; β = -.54, sr(2) = . 03, p = . 044). The relationship between PV and PTSD symptoms was greatest at low and average levels of domestic violence coping self-efficacy and nonsignificant at high levels of domestic violence coping self-efficacy. These findings highlight the importance of assessing domestic violence coping self-efficacy in incarcerated women with recent PV, given that domestic violence coping self-efficacy appeared to be protective against symptoms of PTSD.
Engaging stakeholders through Facebook. The case of Global Compact LEAD participants

Facebook has deeply modified the way people communicate and interact. From a business perspective, Facebook has enormous potential as a means of communication and stakeholder engagement. It enables companies to share contents rapidly and efficiently with a large number of stakeholders worldwide. People can personalise their Facebook profile to receive updates from selected companies. Moreover, people can reply to such posts or simply manifest their approval by liking or sharing the posts. In this way, people also propagate corporate information among their own friends.The dramatic diffusion of Facebook should encourage companies to virtually interact with a network of stakeholders 2.0, using Facebook as a stakeholder engagement tool.The evolution to Web 2.0 goes with a general change in the social and business environment. In today? s world, both policy makers and the public expect that companies work in a sustainable way and consult their stakeholders about corporate strategies, operations and performance. The discussion should concern social and ecological cares as well as economic issues. In this sense, the engagement of the Facebook community could considerable enlarge and improve the dialogue.This paper offers a theoretical and empirical analysis to answer the following research question: do sustainability-oriented companies use Facebook as an effective means of stakeholder engagement? The paper contains an investigation based on UN Global Compact LEAD members, characterised by strong commitment and cooperation with governments, civil society, labour and the UN in order to promote sustainable practices. To evaluate the contribution of Facebook to the dialogue on sustainability, the investigation considered the types of contents published by the LEAD companies on their Facebook pages in 30 days. According to the subject, seven categories of posts emerged from the analysis: human rights and social citizenship; labour; environment; anti-corruption; strategy, business activity and economic performance; news on products and services; other.To evaluate the use of Facebook for stakeholder engagement 2.0, the investigation verified how many ? likes? , comments and ? shares? each post received and how often the company replied.The analysis showed that some LEAD members did not have a Facebook profile, which is unacceptable nowadays. Moreover, the companies with an official page rarely covered all three perspectives of sustainability (social, environmental, and economic issues). Furthermore, companies rarely replied to stakeholders? comments. Based on the empirical evidence, most LEAD participants should modify the way they used Facebook. Therefore, the results of this research may help them improve stakeholder engagement 2.0.
A Cross-Country Study on the Relationship between Financial Development and Earnings Management

This paper investigates whether a country’s level of financial development is associated with earnings management in an international setting. Financial development is likely to heighten the monitoring and scrutiny of accounting numbers because of strengthened investor protection laws and regulations as well as sophisticated market participants. Therefore, we first hypothesize that both accrual-based and real earnings management decrease with greater financial development. However, research shows that managers tend to apply real earnings management, instead of accrual-based earnings management, under strict accounting standards, regulations, and close auditor scrutiny. Thus, we explore the alternative hypothesis that accrual-based earnings management decreases but real earnings management increases along with higher financial development. We examine the relationship between financial development and both types of earnings management using 56,830 observations in 37 countries covering the period 2009 to 2012. The results indicate that both types of earnings management are more restrained under higher levels of financial development.
α-Synuclein Overexpression Increases Cytosolic Catecholamine Concentration

Dysregulation of dopamine homeostasis and elevation of the cytosolic level of the transmitter have been suggested to underlie the vulnerability of catecholaminergic neurons in Parkinson’s disease. Because several known mutations in α-synuclein or overexpression of the wild-type (WT) protein causes familial forms of Parkinson’s disease, we investigated possible links between α-synuclein pathogenesis and dopamine homeostasis. Chromaffin cells isolated from transgenic mice that overexpress A30P α-synuclein displayed significantly increased cytosolic catecholamine levels as measured by intracellular patch electrochemistry, whereas cells overexpressing the WT protein and those from knock-out animals were not different from controls. Likewise, catechol concentrations were higher in l-DOPA-treated PC12 cells overexpressing A30P or A53T compared with those expressing WT α-synuclein, although the ability of cells to maintain a low cytosolic dopamine level after l-DOPA challenge was markedly inhibited by either protein. We also found that incubation with low-micromolar concentrations of WT, A30P, or A53T α-synuclein inhibited ATP-dependent maintenance of pH gradients in isolated chromaffin vesicles and that the WT protein was significantly less potent in inducing the proton leakage. In summary, we demonstrate that overexpression of different types of α-synuclein disrupts vesicular pH and leads to a marked increase in the levels of cytosolic catechol species, an effect that may in turn trigger cellular oxyradical damage. Although multiple molecular mechanisms may be responsible for the perturbation of cytosolic catecholamine homeostasis, this study provides critical evidence about how α-synuclein might exert its cytotoxicity and selectively damage catecholaminergic cells.

Crystal Structure of the Ubiquitin-like Domain-CUT Repeat-like Tandem of Special AT-rich Sequence Binding Protein 1 (SATB1) Reveals a Coordinating DNA-binding Mechanism*

Background: SATB1 is a multidomain protein that acts as a global gene organizer. Results: The newly identified CUTL domain contributes to the DNA binding ability of SATB1. Conclusion: The DNA binding ability of SATB1 requires the contribution of the CUTL domain and the other DNA-binding domains. Significance: These findings reveal a multiple-domain-coordinated mechanism whereby SATB1 recognizes DNA targets. SATB1 is essential for T-cell development and growth and metastasis of multitype tumors and acts as a global chromatin organizer and gene expression regulator. The DNA binding ability of SATB1 plays vital roles in its various biological functions. We report the crystal structure of the N-terminal module of SATB1. Interestingly, this module contains a ubiquitin-like domain (ULD) and a CUT repeat-like (CUTL) domain (ULD-CUTL tandem). Detailed biochemical experiments indicate that the N terminus of SATB1 (residues 1–248, SATB1(1–248)), including the extreme 70 N-terminal amino acids, and the ULD-CUTL tandem bind specifically to DNA targets. Our results show that the DNA binding ability of full-length SATB1 requires the contribution of the CUTL domain, as well as the CUT1-CUT2 tandem domain and the homeodomain. These findings may reveal a multiple-domain-coordinated mechanism whereby SATB1 recognizes DNA targets.
The impact of market liberalization on vertical scope: the case of Argentina

This paper analyzes the impact of market liberalization on the vertical scope of firms. Using the case of Argentina, it is shown how the opening of the economy can improve contracting abilities and heighten competition, increasing the ability and incentive of firms to outsource. Survey findings support the main hypothesis as well as the specific importance of reforms relating to inflation, import costs, and heightened demand standards in increasing the use of outsourcing. A case study of the steel producer Siderar, highlights that while firms may reduce their presence in peripheral activities, they may also increase their presence in core areas so as to increase their value proposition.

Barriers to practical use of academic marketing knowledge

It is commonly assumed that a prime purpose of developing research‐based marketing knowledge is that it should be useful to marketing managers and other practitioners. However, evidence suggests that academic marketing knowledge is only to a limited degree utilised in practical life. It is thus important to understand why this is the case, as well as how use of academic knowledge can be enhanced. This paper focuses on scientific knowledge about market orientation and explores a range of factors, which might impair its practical application. More specifically, it examines what types of knowledge marketing practitioners might perceive as useful and discusses a range of potential barriers to successful transfer of market orientation knowledge from academia to practitioners. Substantial barriers are identified which relate to attributes of market orientation knowledge itself and characteristics of both academics and practitioners. Findings are discussed and implications highlighted.

Farmland Liquidation and Transaction Costs

This paper discusses why progress in farmland liquidation through leasing has been very slow in the agricultural sector in Japan, focusing on the transaction costs related to farmland leasing. First, this paper points out that transaction costs are an important constraint for farmland leasing, and argues by means of a survey of related studies, why transaction costs have a strong association with farmland. Next, it explores using partial equilibrium analysis how the aggregated demand and supply of farmland is affected by the changes in the farmers' activities that face a transaction cost. Following this, the paper estimates the extent to which farmland leasing is affected by the characteristics of farmland and local communities. The data used in the analysis is the prefectural panel data of the agricultural census for the years 1980, 1990, and 2000; the data excludes Hokkaido, Tokyo, Kanagawa, Osaka, and Okinawa. The result of the econometric analysis shows that the level of farmland leasing is related to the variables representing the activities of local communities and the characteristics of farmland such as land improvement and conversion of farmland. These results emphasize the importance of developing and reinforcing institutions and organizations to lower the transaction costs in the farmland market.
ENVIRONMENTAL COMMUNICATION AND SUSTAINABLE DEVELOPMENT IN MALAYSIA: AN ANALYSIS ON ENVIRONMENTAL NGOs WEBSITES DESIGN

Environmental concern has become increasingly integrated into the public domain and mainstream, traditional, and new media. Investigations into the phenomena of environmental communication (EC) using online advocacy are increasingly trans-disciplinary endeavors. My research question focused on how the websites design of the environmental NGOs in Malaysia (ENGOM) can effectively support the sustainability development in Malaysia. The result shows that the majority of the ENGOM websites met the ‘well designed’ requirements. The outcome of this study can especially helps environmental organisations develop the Internet and the web strategies which take into account the issues examined herein, in order to best utilise this medium for their purposes. The usability test was suggested to evaluate the user’s point of view regarding what constitutes an effective and well designed environmental website. Keywords: environmental communication; environmental NGOs, homepage, internet, web design, web page, website.
Inducible transcriptional activation of the human immunodeficiency virus long terminal repeat by protein kinase inhibitors

The protein kinase inhibitor 2-aminopurine (2-AP) greatly stimulated expression in human promonocytes-macrophages of plasmid constructs carrying various reporter genes (chloramphenicol acetyltransferase, lacZ, firefly luciferase [luc], and Salmonella typhimurium histidinol dehydrogenase [his]) driven by the human immunodeficiency virus type 1 (HIV-1) long terminal repeat. Adenine, adenosine, and caffeine were also effective inducers, but other purine or pyrimidine derivatives were ineffective. Experiments with mutant derivatives of the HIV-1 long terminal repeat revealed no specific eukaryotic promoter elements necessary for 2-AP induction but indicated the need for some minimum combination of such elements. Induction of HIV-1-directed gene expression appeared not to require action of the transcription factor NF-kappa B. The mechanism of induction was investigated by using the luc and his genes linked to the HIV-1 long terminal repeat. 2-AP induced marked, steady rises in mRNA accumulation from both transfected and chromosomally integrated HIV-1 constructs but no increases from an endogenous gene encoding gamma-actin or glucose 6-phosphate dehydrogenase. Thus, induction is selective and not an artifact induced by transfecting DNA into cells. In run-on transcription experiments, the rates of transcription initiation of both transfected and integrated copies of the his gene increased about sixfold in cells treated with 2-AP. Thus, while increased initiation accounted for a portion of 2-AP induction, it could not cause the far greater increase in steady-state mRNA levels. 2-AP induction did not change mRNA decay rates and differed from the phorbol ester (phorbol myristate acetate)-induced activation of the protein kinase C-NF-kappa B pathway in its time course and in its requirement for new protein synthesis. Gel retardation assays showed that unlike phorbol myristate acetate induction, 2-AP induction is enhancer independent. Whereas many previous studies have implicated the activation of various protein kinases in gene induction, we here describe a mechanism of gene activation that appears to involve protein kinase inhibition as a component of the induction response.

Resource Allocation for D2D Wireless Networks With Asymmetric Social Weighted Graph

Different from the existing symmetric social relation graph, we first utilize a new asymmetric social weighted graph to study the problem of resource allocation for Device-to-Device (D2D) wireless social networks. We propose a social-aware cluster-based game theoretical scheme for resource allocation in which clusters are formatted based on the new defined weighted social interference degree and the physical interference graph. In the proposed cluster-based game scheme, we shrink action spaces of players (clusters) through a determined channel allocation rule. Simulation results show that the proposed cluster action selection algorithm has a higher convergence speed and a better social network interference performance.
The cell kinetics of human mammary cancers

The cellular kinetics of human mammary tumors were studied by in vitro methods. These techniques include single 3HTdR labeling to measure the 3HTdR LI, double labeling with 3HTdR and 14CTdR to measure DNA synthesis time, and an estimation of the growth fraction by the PDP index. Calculations of the potential doubling time and cell cycle time were made from these measurements. The 3HTdR LI of primary malignant tumors was greater than that of benign tumors, but only half that of metastatic lesions. There was considerable heterogeneity in the 3HTdI LI of primary tumors, but the DNA synthesis times were relatively invariant. Estimation of the growth fraction by the PDP index also revealed extensive heterogeneity, but the primary tumors were not different from metastases. There appear to be subsets of tumors with high and low proliferative values that correlate with some clinical parameters, such as age and nodal positivity. This material provides a data base for stratification of patients for future protocols and the use of cell kinetics in treatment programs.
