Teaching Static Call Analysis to Detect Anomalous Software Behavior

Malicious code detection is a critical part of any cyber security operation. Typically, the behavior of normal applications is modeled so that deviations from normal behavior can be identified. There are multiple approach to modeling good behavior but the most common approach is to observe applications’ system call activity. System calls are messages passed between user space applications and their underlying operating systems. The detection of irregular system call activity signals the presence of malicious software behavior. This method of malware-detection has been used successfully for almost two decades. Unfortunately, it can be difficult to cover this concept at the right level of detail for undergraduate information systems students. Some instructors provide only superfluous descriptions of malware, others delve into in-depth reviews of application code. This paper advocates an approach which teaches the fundamentals of code analysis to nonprogrammers. The approaches integrates visualization tools such as flame graphs to help students interpret software behavior. It has been found to be especially valuable for upper division information systems courses on cyber security.

Role of excessive maternal iron in the pathogenesis of congenital leukoencephalomalacia in captive black rhinoceroses (Diceros bicornis).

OBJECTIVE To investigate the possibility that excessive maternal iron (overload) may contribute to development of congenital leukoencephalomalacia in captive black rhinoceroses. SAMPLE POPULATION Tissue specimens and serum samples from 18 rhinoceroses in 2 kindreds harboring 4 (possibly 5) affected female calves. PROCEDURE Fresh and archival sera and necropsy tissue specimens were evaluated to determine the nature and extent of iron overload in captive and wild black rhinoceroses as well as other rhinoceros species. RESULTS Quantitative serum and tissue assays of iron and iron analytes, corroborated by histopathologic findings, indicated that these kindreds carried the greatest body burdens of iron yet found among captive black rhinoceroses. Fourteen of 18 rhinoceroses had the highest serum ferritin concentrations measured among 64 black rhinoceroses in captivity in the United States. Dams of affected calves had serum ferritin concentrations 2 orders of magnitude higher than clinically normal humans, equids, or free-ranging rhinoceroses. A neonatal serum sample from 1 affected female calf had a high ferritin concentration (approx 100-fold increase), but a male sibling of another affected female did not, suggesting a possible sex disparity in fetal response to maternal iron overload. Morphologic hallmarks of hemochromatosis were prominent in dams and grandams of affected calves. CONCLUSIONS AND CLINICAL RELEVANCE Excessive maternal iron may affect female fetuses more than males, possibly inducing leukoencephalomalacia by catalyzing production of highly toxic hydroxyl free radicals during crucial periods of in utero development. Reduction of maternal iron overload may decrease the probability of developing leukoencephalomalacia and some other disorders commonly affecting rhinoceroses in captivity.
Diskrete Mathematik und Optimierung

It is well-known that there are instances of the binary paint shop problem for which the recursive greedy heuristic is better than the greedy heuristic. In this note, we give an example of a family of instances where the greedy heuristic is better than the recursive greedy heuristic, thus showing that these heuristics are uncorrelated.
Accelerated formation of multicellular 3‐D structures by cell‐to‐cell cross‐linking

The three‐dimensional (3‐D) arrangement of cells within tissues is integral to their development and function. Advances in stem cell science and regenerative medicine have stimulated interest in the replication of this architecture in vitro. We have developed a versatile method for controlling short‐term cell–cell and cell–matrix interactions via a facile cell surface engineering process that enables the rapid formation of specific 3‐D interactions for a range of cell types. We demonstrate that chemical modification of cell surfaces and matrix proteins can artificially accelerate the cell adhesion process and confirm the ability to control the formation of multicellular aggregates with defined architectures and heterotypic cell types. Direct comparison with a natural aggregation process seen during differentiation of embryonic stem (ES) cells revealed increased expression of developmental regulatory proteins and a concomitant enhancement of ES cell differentiation. Furthermore, this new methodology has numerous applications in generating layered structures. For example, we demonstrate improved transfer of therapeutic human keratinocytes onto a dermal layer in a skin repair model. Biotechnol. Bioeng. 2007; 97: 1617–1625. © 2007 Wiley Periodicals, Inc.
Internet financial reporting-practice of listed companies from Sarajevo stock exchange

Financial reporting in countries with developed capital markets plays a very important informative role. Reporting and disclosure according to modern accounting frameworks (FASB & IASB) is aimed to provide useful information, reduce information asymmetry and cost of capital. Today, the Internet can be very effectively used for dissemination of financial information to investors and other users. Therefore, the issue of financial reporting has a new dimension and many scientific papers analyze Internet reporting practices of listed companies in the USA and EU countries. The issue of Internet reporting in transitional countries is also becoming more important since capital markets are growing very strongly and there is an increasing number of domestic and foreign investors. Since voluntary Internet reporting has not been scientifically analyzed in Federation Bosnia and Herzegovina (FBiH) there is a very good opportunity for research and contribution to the existing literature. Therefore research was conducted on the sample of listed companies from the Sarajevo Stock Exchange (SASE). The average IFR-Score for 35 companies from SASE came to just 5.43, while maximum score of 30 was not found on the web site of any company listed at SASE. Regression model, comprising data for 33 companies has shown that the size, profitability and industries were not significant in explaining voluntary Internet disclosure measured by IFR-Score. However, official listing, market capitalization percentage and stock turnover were statistically significantly and positively correlated with the IFR-Score. Findings on average indicate that corporations from SASE do not follow modern trends in financial reporting and there is large area for improvement of reporting practice. Having in mind the growth of SASE and its importance in the FBiH economy system it is crucial to improve transparency and disclosure in order to improve investor protection and attract foreign investors.
An Empirical Study on the Pedagogy of Multiliteracies of Business English Course

Multiliteracies was coined in response to two significant changes in globalized environments: the proliferation of diverse modes of communication through new communications technologies such as the internet, multimedia, and digital media, and the existence of growing linguistic and cultural diversity due to increased transnational migration[1]. The main purpose of traditional English language pedagogy focuses on teaching and learning languages. So it is necessary to change the traditional teaching way in business English curriculum and emphasize students’ multiliteracies ability to adapt the changing business world. This empirical research on the “Pedagogy of Multiliteracies of Business English Course” is conducted in foreign language department of Harbin University of Commerce. It shows that the Pedagogy of Multiliteracies has a positive influence in business English language acquisition and cross-cultural learning.
Security and Privacy in Vehicular Social Networks

We surveyed and presented the state-of-the-art VC systems, security and privacy architectures and technologies, emphasizing on security and privacy challenges and their solutions for P2P interactions in VSNs towards standardization and deployment. We note that beyond safety applications that have drawn a lot of attention in VC systems, there is significant and rising interest in vehicle-to-vehicle interaction for a range of transportation efficiency and infotainment applications, notably LBS as well as a gamut of services by mobile providers. While this enriches the VC systems and the user experience, security and privacy concerns are also intensified. This is especially so, considering (i) the privacy risk from the exposure of the users to the service providers, and (ii) the security risk from the interaction with malicious or selfish and thus misbehaving users or infrastructure. We showed existing solutions can in fact evolve and address the VSN-specific challenges, and improve or even accelerate the adoption of VSN applications.
I-like R plasmids promote degradation of stable ribonucleic acid in Escherichia coli

Some I-like R plasmids, R483, R144, R64drd-11 and R621a, belonging to compatibility groups IncI alpha and I gamma promoted degradation of stable RNA in the srnA1 cells of Escherichia coli after addition of rifampin at 42 degrees C. R16 and R834 plasmids of compatibility group IncB also promoted the degradation of RNA. However, other many kinds of plasmids did not. The promotion of RNA degradation was delayed by the addition of chloramphenicol with rifampin.
COGNITIVE FLEXIBILITY, PERCEPTION OF INTEGRITY, AND RISK PROPENSITY AS ANTECEDENTS OF WILLINGNESS TO ENGAGE IN INTEGRATIVE NEGOTIATION

Integrative negotiation is the type of negotiation reputed to generate the most positive results, since it focusses on reaching win-win solutions and aims to increase joint outcomes. The purpose of this article is to analyse variables which may foster willingness to engage in integrative negotiation. More specifically, the study investigates two variables that have not been studied in previous research on integrative negotiation - cognitive flexibility and perception of integrity. It also includes one variable which has been widely researched, but for which inconsistent results have been reported – risk propensity. Results show that, while the alternatives subscale of cognitive flexibility is a predictor of willingness to engage in integrative negotiation, the same does not hold for the control subscale. Results also show that perception of integrity is a predictor of willingness to engage in integrative negotiation, while there is no significant association between risk propensity and willingness to engage in integrative negotiation. Theoretical contributions and practical application for training in negotiation are discussed. Classification- JEL:
CRM 2.0 and Mobile CRM: a framework proposal and study in European recruitment agencies

Companies are becoming more focused on customers and on new ways to approach them individually. Mobile technologies and Web 2.0 have been pushing companies to evolve in this area. This research is focused on the way Customer Relationship Management (CRM) systems are used, on a European level, by recruiting companies to assist candidates in finding a satisfactory job. A framework is presented to identify how CRM 2.0 and mCRM (mobile CRM) can help candidates to find jobs in a personalized way. A set of four hypotheses have been defined. To gain a better understanding of these CRM systems, the methodology used in the exploratory study was quantitative, employing a non-probabilistic sampling technique, with 35 recruiting agencies being studied. Results showed that the use of software in recruiting agencies is quite common and that CRM 2.0 is present in the vast majority of the studied companies. When it comes to mobile CRM, there's still much to be explored in this channel, as agencies focus their resources on Web 2.0, leaving this channel's great potential of mobile CRM unused.
User mobility prediction based on Lagrange's interpolation in ultra-dense networks

The concept of Ultra-Dense Networks (UDNs) was first introduced by Mobile and wireless communications Enablers for the Twenty-twenty Information Society (METIS) and it is considered as a promising technology in the future 5G. In UDNs, due to the dense deployment of femtocells, building User-Centric Networks (UCNs) is a clear trend and Virtual Cells (VCs) are the core function of UCNs. As user mobility prediction can enhance the mobility of UCNs and improve the handover performance of VCs, it is a critical issue in UDNs. Unfortunately, to the best of our knowledge, no literatures about user mobility prediction in UDNs are available. At present, most existing mobility prediction works are carried out in LTE networks and they only consider the cells which are uniformly distributed. What's more, as femtocells are densely deployed, the existing prediction works cannot be applied to UDNs directly. Therefore, we are trying to find a practical scheme with lower algorithmic complexity which can be applied to UDNs. In this paper, we explore a realistic block scenario with femtocells deployed according to Poisson Point Process (PPP). Exploiting context information, we propose a novel approach which fitting users' moving path based on Lagrange's interpolation. We evaluate users' transition probability to neighboring femtocells according to the slope of the trajectory polynomial and the distance between users and neighboring femtocells. Simulation results show that when choosing synchronous transmission points (TPs) based on the distance between users and neighboring TPs, five TPs with the highest transition probability can achieve the highest prediction accuracy. Besides, the combination of distance and direction can reduce the number of synchronous TPs without decreasing the prediction accuracy and it would perform better at a higher speed.
Maximum Entropy Models for Word Sense Disambiguation

A maximum entropy-based word sense disambiguation system is presented, consisting of individual word experts that are trained on both labeled and partially labeled corpora. The classification probabilities from the individual word experts are integrated using a new search algorithm, which balances time complexity and accuracy. The model is evaluated using established procedures on the English-all-words task from the SENSEVAL-2 workshop, a large test set consisting of words from all word groups to be disambiguated. Lastly, an ongoing project that integrates POS tagging, parsing, and sense disambiguation in one system is presented. Once in place, it will be boot-strapped with existing partially labeled corpora, to process and then train from them. The goal is to show that with each successive iteration, the accuracy of all three processes, POS tagging, parsing, and WSD, will improve as the system learns from more accurate, self-generated training data.
Acute Myeloblastic Leukemia after Adjuvant Chemotherapy with Melphalan in Breast Cancer. Case Report with Cytogenetic Analysis

Therapy of solid and hematologic tumors with alkylating agents appears to increase the frequency of acute non-lymphocytic leukemia (ANLL), as indicated by the cases reported in the literature. The carcinogenetic mechanism of alkylating agents seems related to their ability to damage DNA, and this is supported by the findings of multiple cytogenetic abnormalities in these patients. We report a case of ANLL secondary to therapy with melphalan, which was utilized on an adjuvant basis for breast cancer. ANLL developed 24 months after chemotherapy was discontinued. Results of the cytogenetic analysis in our patient showed multiple rearrangements and marker chromosomes. Among these was a large metacentric chromosome, identified in 6 of 8 karyotypes, in the size range of group A, which probably resulted from a translocation t(7;14) (7qter→7p11::14p11-→14qter). The natural history of the underlying disease and of the ANLL in our patient and data from chromosomal analysis seem to confirm the hypothesis that alkylating agents are potentially leukemogenic in man, probably through genetic damage. This possibility should be considered when such cytotoxic drugs are used in an adjuvant setting.
Membrane topology of the melibiose permease of Escherichia coli studied by melB-phoA fusion analysis.

In order to study the secondary structure of the melibiose permease of Escherichia coli, 57 melB-phoA gene fusions were constructed and assayed for alkaline phosphatase activity. In general agreement with a previously suggested secondary structure model of melibiose permease [Botfield, M. C. , Naguchi, K. , Tsuchiya, T. , & Wilson, T.H. (1992) J. Biol. Chem. 267, 1818], clusters of fusions exhibiting low and high phosphatase activity fusions alternate along the primary sequence. Fusions with high activity generally cluster at residues predicted to be in the periplasmic half of transmembrane domains or in periplasmic loops, while fusions with low activity cluster at residues predicted to be in the cytoplasmic half of transmembrane domains or in cytoplasmic loops. Taken together, the findings strongly support the contention that melibiose permease contains 12 transmembrane domains that traverse the membrane in zigzag fashion connected by hydrophilic loops that are exposed alternatively on the periplasmic or cytoplasmic surfaces of the membrane with the N and C termini on the cytoplasmic face of the membrane. Moreover, on the basis of the finding that the cytoplasmic half of an out-going segment is sufficient for alkaline phosphatase export to the periplasm while the periplasmic half of an in-going segment prevents it [Calamia, T. , & Manoil, C. (1990) Proc. Natl. Acad. Sci. U.S.A. 87, 4937], the activity profile of the melibiose permease-alkaline phosphatase fusions is consistent with the predicted topology of seven of 12 transmembrane segments. However, five transmembrane domains require adjustment, and as a consequence, the size of the central cytoplasmic loop is reduced and a significant number of charged residues are shifted from a hydrophilic to a hydrophobic domain in this region of the transporter.
The well-being of children in food-insecure households: results from The Eastern Caribbean Child Vulnerability Study 2005

Abstract Objective To examine the relationship between food insecurity and child well-being indicators. Design Cross-sectional survey conducted in 2344 households with children. The main exposure measure was food insecurity status, which was categorized as food secure or food insecure based on two or more food insecurity questions answered in the affirmative. Multiple logistic regression analysis was used to model the association between food insecurity status and selected child well-being indicators. Setting Barbados, St. Lucia and St. Vincent and the Grenadines (hereafter St. Vincent), three Eastern Caribbean countries, 2005. Subjects A random sample of households with children was identified by the governments of Barbados, St. Lucia and St. Vincent. In-home interviews were conducted by social workers. Results One-third (33 %) of households were categorized as food insecure. Food-insecure households were more likely to include a chronically ill parent (OR = 2·48; 95 % CI 1·76, 3·49), a recently divorced parent (OR = 1·92; 95 % CI 1·21, 3·05), a child requiring multiple visits to a health-care provider for a disability (OR = 3·98; 95 % CI 1·20, 13·19) or injury (OR = 1·78; 95 % CI 1·12, 2·83), a child with a learning disability (OR = 2·08; 95 % CI 1·16, 3·74) or a child with a physical disability (OR = 2·54; 95 % CI 1·22, 5·32) after adjustment for poverty and other demographic variables. Conclusions The results indicate that food-insecure households were more likely to be burdened by child disability (learning and physical), family system disruption (recent divorce and chronic illness) and child health-care needs (for disability and injury) than food-secure households. The implementation of programmes and policies to minimize food insecurity in the Eastern Caribbean may be warranted.
Effect of dose-rate ( -radiation) on the mitotically-active and differentiating germ cell of the prenatal male rat.

SummaryRat foetuses, aged 15, 17, or 19 days of gestation were subjected to 95 rads of 60Co γ-radiation administered at rates of 0·95, 9·5 or 45 rads/min and examined 6, 28, and 49 days after birth. Dose-rate effects were assayed at day 6 by enumerating germ cells in 150 cross sections of seminiferous tubules and measuring testicular weights. At days 28 and 49, dose-rate effects were determined by means of testicular weights and counts of fertile and sterile tubular cross-sections.Germ-cell survival was inversely related to age at irradiation. Dose-rate effects were pronounced (P < 0·05) in testes iradiated at day 15 (germ cells mitotically active), equivocal at day 17 (germ cells mitotically active and differentiating), and absent at day 19 (germ cells differentiating only). Both testicular weights and tubular counts measured at day 28 were apparently directly related to the germ-cell counts.The mitotically-active gonocyte was comparatively refractory to the necrotizing effects of ionizing radiation, and.
Benefits and Difficulties of Organic and Conventional Rice Farming Systems in Bali, Indonesia

Development of organic farming in Indonesia started in the 1980s, especially in Java. Recently we can easily ﬁnd organic rice products at supermarkets in Indonesia, however, some products are not ofﬁcially certiﬁed as organic agricultural products. According to the Bali Agricultural Agency, only 5 groups were certiﬁed for organic rice farming as of 2013. In this study, we interviewed organic and conventional farmers in a town in Bali and analyzed rice growth in their ﬁelds to reveal the beneﬁts and difﬁculties of organic rice cultivation from economic and biological perspectives. In the interviews, all of the organic farmers indicated that they implemented organic systems because the production cost is less than that of conventional systems and the price paid to farmers for organic rice is higher than for conventional rice. Consistent with these replies, the calculated revenue/ cost ratio of orga nic farming was signiﬁcantly higher than that of conventional farming.
