Towards a Reformulation of Monetary Theory: Competitive Banking
Creators: name: Stiglitz, Joseph E.
name: Greenwald, Bruce C.
Publisher: name: Columbia University
Year: 1991
Subjects: Economics

description: This paper, after providing a critique of standard monetary theory based on the transactions demand for money, examines the effect of monetary policy (changes in reserve requires and open market operations) in a model with competitive, risk averse banks. The effects of changes in bank net worth and bank's risk perceptions are also analyzed. In deep recessions, monetary policy may be ineffective because banks are unwilling to lend. The effects of monetary policy are, at most, only partially mediated through changes in the interest rate. The implications for traditional IS-LM analysis are briefly noted.

Characterization of photonic crystal silicon-on-insulator optical circuits fabricated by a CMOS foundry
Creators: name: Schelew, Ellen N.
Publisher: name: University of British Columbia
Year: 2011

description: Prototype silicon photonic circuits in a silicon-on-insulator (SOI) wafer fabricated using a CMOS-based single layer process, are thoroughly characterized. Thousands of devices were fabricated on a single 200 mm diameter wafer using deep UV lithography at the IMEC silicon photonics foundry. The devices studied integrate three key elements: i) input/output grating couplers, ii) waveguides, and iii) microcavities. The photonic crystal cavities are symmetrically coupled to input and output single mode channel waveguides, which couple light into tapered waveguides that are terminated by two-dimensional photonic crystal gratings couplers. The grating coupler efficiencies and bandwidths are studied independently from the other device components, both experimentally and by simulations, using free-space optics. At a fixed angle of incidence, light over a bandwidth of approximately 14 nm (TE) and 30 nm (TM) is coupled from grating to grating, in both experiments and simulations. The centre frequency of this coupling spectrum is tuned by varying the angle of incidence on the grating, by coating the grating with photoresist, and by varying the size of the holes that form the grating. The maximum net single-grating coupling efficiencies are measured to be 15% (26%) for TE (TM) coupling. Taking into account the limited aperture of the collection optics, and aberrations of the input coupling lenses, these measured net efficiencies are reasonably consistent with simulated true efficiencies of 21%(49%) found using Lumerical FDTD Solutions and MODE Solutions commercial software. Resonant transmission measurements from free space, via an input grating, through the complete integrated photonic circuit, including the photonic crystal microcavity, and off-chip via an output grating are measured for a number of different cavities. The transmission of light from the end of one tapered waveguide, through the cavity, to the end of the other tapered waveguide is found to be ~10%. The maximum microcavity quality factor measured is ~ 5000. This work demonstrates that fully integrated photonic circuits can be successfully fabricated using IMEC's CMOS foundry service. It further shows that useful overall coupling efficiencies can be realized using free space optics, which will be useful for probing such circuits when they are placed inside optical cryostats.

description: This thesis presents a concept hierarchy-based approach to pnvacy preservmg data collection for data mining called the p-level model. The p-level model allows data providers to divulge information at any chosen privacy level (p-level), on any attribute. Data collected at a high p-level signifies divulgence at a higher conceptual level and thus ensures more privacy. Data providers have greater control of their privacy preferences, and have provided significantly (25-75%) more personal data values, at various p-levels, than when providing the same information using the regular, fixed-level Cf-level) method of data collection. However, the data mining process, which involves the integration of various data values, can constitute a privacy breach if combinations of attributes at the various p-levels result in the inference of knowledge that exists at lower p-levels. Providing anonymity guarantees prior to release can further protect the collected data set from privacy breaches due to linking the released data set with external data sets. This thesis describes the p­level reduction phenomenon and proposes methods to identify and control the occurrence of this privacy breach. One objective of this thesis is to explore the feasibility of applying data collected with the p-level approach to data mining problems. We apply data collected using the p-level approach to a data classification problem, and discover that the mining accuracy of the p­level approach classifier is comparable to that of the f-level (no privacy) approach, thus we conclude that the p-level approach is beneficial for the purpose of privacy preserving data collection.

description: The techniques for optical calibration of Jefferson Lab's large-acceptance magnetic hadron spectrometer, BigBite, have been examined. The most consistent and stable results were obtained by using a method based on singular value decomposition. In spite of the complexity of the optics, the particles' positions and momenta at the target have been precisely reconstructed from the coordinates measured in the detectors by means of a single back-tracing matrix. The technique is applicable to any similar magnetic spectrometer and any particle type. For 0.55 GeV/c protons, we have established the vertex resolution of 1.2 cm, angular resolutions of 7 mrad and 16 mrad (in-plane and out-of-plane, respectively), and a relative momentum resolution of 1.6%.

The proxemic peddler framework: designing a public display that captures and preserves the attention of a passerby

description: Effective street peddlers monitor passersby, where they tune their message to capture and keep the passerby's attention over the entire duration of the sales pitch. Similarly, advertising displays in today's public environments can be more effective if they were able to tune their content in response to how passersby were attending to them vs. just showing fixed content in a loop. Previously, others have prototyped displays that monitor and react to the presence or absence of a person within a few proxemic (spatial) zones surrounding the screen, where these zones are used as an estimate of attention. However, the coarseness and discrete nature of these zones mean that they cannot respond to subtle changes in the user's attention towards the display. In this thesis, we contribute an extension to existing proxemic models. Our Peddler Framework captures (1) fine-grained continuous proxemic measures by (2) monitoring the passerby's distance and orientation with respect to the display at all times. We use this information to infer (3) the passerby's interest or digression of attention at any given time, and ( 4) their attentional state with respect to their short-term interaction history over time. Depending on this attentional state, we tune content to lead the passerby into a more attentive stage, ultimately resulting in a purchase. We also contribute a prototype of a public advertising display - called Proxemic Peddler - that demonstrates these extensions as applied to content from the Amazon.com website.

description: This work studies an approach for gathering requirements, designing and developing an interactive collaborative multi-touch tabletop Geographic Information System (GIS) in an agile software development environment to support the operation of control centers in utility companies and potentially other similar domains. The research is based on two case studies. The first study focuses on agile approaches for gathering requirements and iteratively designing gesture-based, multi-touch GIS applications utilizing digital tables, where a prototype - eGrid - is developed for supporting the operation of the control centre in a local electricity company. The design is iteratively enhanced and assessed through interviews and observation sessions. The second study proposes an agile approach for generalizing the design and extracting a library of reusable components - GISforTT - to support the development of other interactive GIS applications. The two studies proposed agile software engineering practises that were found helpful in designing and supporting reuse of interactive tabletop applications.

description: Fake news is another word for “disinformation”. It means information that looks and sounds like true, but which is false or not totally true. Sometimes, even if statements might be false, the events they are referring to might be real.
 Fake news is made to look like news: it is catchy so that it attracts the attention of more readers and gets more clicks or shares.
 The aims of this content are different: sometimes it is to mislead and manipulate the public, for ideological or economic gains (Baptista & Gradim, 2022). However, sometimes it can happen that fake news comes from lack of understanding and full knowledge of a situation.

More precisely, given a positive integer $n$, we find a class of cardinality approximately $\sqrt{n}$ whose elements are the $n$-vertex trees with largest Laplacian energy. The main tool for establishing this result is a new upper bound on the sum $S_k(T)$ of the $k$ largest Laplacian eigenvalues of an $n$-vertex tree $T$ with diameter at least four, where $k \in \{1,...,n\}$.
The Quality of Managers in Centralized vs. Decentralized Organizations
Creators: name: Stiglitz, Joseph E.
name: Sah, R. D.
Publisher: name: Columbia University
Year: 1991
Subjects: Economics

description: The article focuses on the quality of managers in centralized and decentralized organizations. A central task of the leadership of any organization is the choice of its successors and subordinates. Corporate presidents spend a significant part of their time selecting upper management. Tenured faculty sometimes spends months deciding whether particular individuals should be admitted into their ranks. The effort and contentiousness which often go into this process suggests that it has important consequences for the organization. It is recognized that there are large differences in individuals' abilities and that the abilities of those in leadership inevitably affect the performance and survival of the organization. Stylized economies consisting of an arbitrary number of hierarchies of different sizes is considered here. The size of a hierarchy is the number of managers within the hierarchy, one of whom is the hierarch the boss and others are subordinates. The current hierarch appoints his own successor and those of his subordinates, but has no influence on any other hierarchy.

Impact of the Changing Tax Environment on Investments and Productivity: Financial Structure and the Corporation Income Tax
Creators: name: Stiglitz, Joseph E.
name: Greenwald, Bruce C.
Publisher: name: Columbia University
Year: 1989
Subjects: Economics

description: This paper explores the consequences of the corporation income tax when firms face financial constraints; that is, they are either credit- or equity-rationed. (These financial constraints can, in turn, be explained as the natural consequences of informational asymmetries that are pervasive in the capital market.) The paper shows that the effect of such taxes may be more related to average tax rates than to the marginal effective tax rates on which recent literature, analyzing the incidence of such taxes in neoclassical firms, has focused. For firms that are equity- (but not credit-) constrained, the reduction in retained earnings reduces their willingness to undertake risky investments, including R-and-D expenditures which enhance productivity in the long run. More generally, the impact of the tax depends on the structure of taxes as much as it does on the level (the provisions for tax deductibility of interest, the tax treatment of capital gains, and so forth), and an analysis requires taking into account the combined effects of the corporation and individual income tax structures. For instance, for firms that are neither equity-nor credit-constrained, the fact that interest payments are tax-deductible implies that there are no marginal distortions with respect to the level of investment. Higher differential taxes on equity may induce some firms to decide not to issue equity. This financial decision will be accompanied by a discrete reduction in the level of investment.

description: Die vorliegende Arbeit stellt eine Edition des Urbares von St. Georgen am Längsee aus dem Jahr 1486 dar. Dabei handelt es sich um das älteste erhaltene Urbar des Stiftes St. Georgen am Längsee, welches heute im Kärntner Landesarchiv verwahrt wird. Den Auftrag zur Anlegung des Urbars gab die damalige Äbtissin des Benediktinnerinenklosters St. Georgen am Längsee, Magdalena Hellegker. Der Kodex wurde aber, trotz seiner optisch ansprechenden Gestaltung über das ganze 16. Jahrhundert hinweg zum Gebrauch heran gezogen, weshalb sich im gesamten Urbar viele Nachträge und Korrekturen von mehreren Händen finden. Die vorliegende Edition umfasst den Haupttext des Urbars von 1486 und alle darauf bezogene Korrekturen und Nachträge von späteren Händen bis zirka 1610. Das Urbar gliedert sich in insgesamt 17 Ämter, welche in sich nicht nur territorial geordnet wurden, sondern auch nach der Verwendung der Einkünfte. Das Urbar gibt Aufschluss über die abgabepflichtigen Besitzungen des Klosters und gewährt somit einen Einblick in die wirtschaftliche Situation von St. Georgen am Längsee am Ende des 15. Jahrhunderts. Nicht in dieser Edition enthalten sind zwei Urkundenabschriften und die weiterführenden Eintragungen auf den letzten Seiten des Kodex, welche dem Urbar im Laufe des 16. Jahrhunderts, beziehungsweise nach 1600 beigefügt wurden. Im Kommentarteil dieser Arbeit findet sich ein Überblick der mittlerweile über 1000-jährigen Geschichte des Stiftes St. Georgen am Längsee und soll vor allem einen Einblick in die Entstehungs-, sowie Verwendungszeit des Urbars geben. Weiters ist eine ausführliche Beschreibung der Handschrift, als auch eine kodikologische Analyse des Urbars enthalten. Um den Überblick über die im Urbar genannten 245 Ortschaften bieten zu können, wurde sowohl ein Ortsregister, als auch eine graphische Darstellung der Verteilung der identifizierten Besitzungen erstellt und beigefügt.
Limits and consequesnces of nonlocality distillation
Creators: name: Rashid, Jibran
Publisher: name: University of Calgary
Year: 2012

description: Bibliography: p. 93-106
description: Only in the last few decades have we realized how to view quantum nonlocal correlations as possible information theoretic resources rather than as apparent paradoxes. Unfortunately, the past perspective in terms of paradoxes still persists in our considerations of nonlocal boxes (NLBs) that offer stronger than quantum nonlocal correlations. We argue that a more pragmatic approach is to consider the physical framework under which such correlations may be realized. Our consideration immediately yields fruit by allowing us to identify limitations of the NLB model and develop the generalized notion of a quantum nonlocal box (qNLB). We analyze the NLB and qNLB models within the framework of nonlocality distillation protocols. The ability to concentrate the correlations of many identical noisy copies of a nonlocal correlation source is known as nonlocality distillation. The idea is still in its early stages of development and and we pursue it in this thesis. We develop multiple new nonlocality distillation protocols and prove the optimality of non-adaptive distillation protocols for both NLBs and qNLBs. We show that qNLBs offer stronger non-adaptive distillation protocols than NLBs. At the same time, the understanding we develop is that there is no single optimal adaptive protocol for N LB distillation. The choice of which protocol to use depends on the noise parameters for the NLB. Through our investigation of nonlocality distillation protocols we conclude that the qNLB model is a stronger resource for nonlocality than NLBs. The main premise that develops from this conclusion is that the N LB model is not the strongest resource to investigate the fundamental principles that limit quantum nonlocality. As such, our work provides strong motivation to reconsider the status quo of the principles that limit nonlocal correlations under the framework of qNLBs rather than NLBs. As a first step towards the re-examination of such principles, we provide numerical evidence that the distillability of nonlocal correlations depends on properties that are local. We claim that the differing strength of distillation protocols for NLBs and qNLBs can be interpreted as a separation between classical and quantum predictions at the macroscopic level. This implies that there exist quantum correlations that can be observed in principle, at the macroscopic level or that the principle of macroscopic locality identifies exactly the set of quantum correlations.

description: The low-energy physics of systems with spontaneous symmetry breaking is governed by the associated Nambu-Goldstone (NG) bosons. While NG bosons in Lorentz-invariant systems are well understood, the precise characterization of their number and dispersion relations in a general quantum many-body system is still an open problem. An inequality relating the number of NG bosons and their dispersion relations to the number of broken symmetry generators was found by Nielsen and Chadha. In this paper, we give a presumably first example of a system in which the Nielsen-Chadha inequality is actually not saturated. We suggest that the number of NG bosons is exactly equal to the number of broken generators minus the number of pairs of broken generators whose commutator has a nonzero vacuum expectation value. This naturally leads us to a proposal for a different classification of NG bosons.

description: Recent advances in GPS collar technologies for Grizzly bear tracking have produced a drastic increase in the volume of data available for scientific analysis. Machine learning methods seem suited to process this ever-increasing volume of data. Comprehensive understanding of the datasets, machine learning methods and similarity measures is fundamental for research of this kind. To automatically detect frequent movement patterns, the current work implemented three machine learning methods, a Location-Based Services (LBS), a simulated annealing, and a hybrid local alignment approach. Several dataset segmentations were tested to reduce the amount of calculations for similarity measures, without losing relevant data relationships. Mostly based on my fifteen yea.rs of professional experience in the industry of data.base administration and development, I found the current state of commercial data.base man­agement systems (DBMS) mature enough to conduct fully integrated implementations. In my judgment, that assumption was validated by the results of the local alignment method.

In vitro metabolism of 20(S)-protopanaxadiol and its interaction with cytochrome P450 3A4
Creators: name: Chiu, Nga Ting
Publisher: name: University of British Columbia
Year: 2011

description: 20(S)-protopanaxadiol (aPPD) is a ginseng sapogenin and is claimed to be a promising anti-cancer drug candidate. Although bacterial biotransformation of ginsenosides in the gut has been thoroughly studied, few have reported on the metabolism of aPPD. As an orally taken xenobiotic, aPPD must first be absorbed and metabolized in the intestine before it reaches the liver for further metabolism. This thesis compares the metabolite profile and enzyme kinetic profile of aPPD in the human intestinal microsomes (HIM) and liver microsomes (HLM), respectively, and examines the interaction between aPPD and cytochrome P450 (CYP), an essential Phase I xenobiotic metabolizing enzyme. aPPD was incubated with HIM or HLM and NADPH regenerating system. Although we did not perform any detailed NMR structural analysis, three major mono-hydroxylated metabolites and five di-hydroxylated metabolites were identified in HIM and HLM using liquid chromatography mass spectrometry in positive ionization mode. A multiple reaction monitoring method, with m/z 477>459 and 459>441 transitions for mono-hydroxylated metabolites M1-M3, m/z 493>457 and 493>475 transitions for di-hydroxylated metabolites M4-M8, and m/z 443>425 and 425>123 transitions for aPPD, was established for subsequent kinetic study and reaction phenotyping study. aPPD metabolites formation in HIM have a much lower Km value than in HLM. Reaction phenotyping was performed with a panel of specific CYP chemical inhibitors and human recombinant CYP enzymes. CYP3A inhibitors, ketoconazole and troleandomycin, inhibits aPPD monohydroxyl metabolite formation in both HIM and HLM in a concentration dependent manner. Among the human recombinant CYP enzymes assayed, CYP3A4 showed the highest activity in aPPD monohydroxyl metabolite formation followed by CYP3A5. In summary, this study suggests that CYP3A isoforms are the predominant enzymes responsible for aPPD mono-hydroxylation in HLM and HIM.

description: This article addresses the question of the desirability of a tax on transactions in the securities industry. Firms were induced to pay excessive attention to short-term returns rather than long-term concerns. There are four circumstances under which governments frequently resort to selective taxes: the commodity being taxed has a highly inelastic demand, so that the tax has little distortionary effect; the commodity being taxed is a luxury good, consumed largely by the very rich; the commodity being taxed associated with certain benefits provided by the government gasoline and airport taxes; and the commodity being taxed that has some socially undesirable characteristics.

description: A major problem for institutional lenders is ensuring that borrowers exercise prudence in the use of the funds so that the likelihood of repayments is enhanced. One partial solution is peer monitoring: having neighbors who are in a good position to monitor the borrower be required to pay a penalty if the borrower goes bankrupt. Peer monitoring is largely responsible for the successful financial performance of the Grameen Bank of Bangladesh and of similar group lending programs elsewhere. But peer monitoring has a cost. It transfers risk from the bank, which is in a better position to bear risk, to the cosigner. In a simple model of peer monitoring in a competitive credit market, this article demonstrates that the transfer of risk to an improvement in borrowers' welfare.

description: There is a paucity of evidence to guide the management of febrile, critically ill patients without acute brain injury. This pilot, randomized clinical trial assessed the safety and feasibility of administering two different fever control strategies in critically ill adults. The biologic response to fever control was also assessed through analysis of several inflammatory mediators. Of the 179 patients screened for enrolment, 14 were randomized to the aggressive treatment group and 12 to the permissive group. The most common reason for exclusion from the trial was the presence of liver disease (22.2%). There were no significant differences in any of the markers of safety, and the fever control strategies did not appreciably influence the biology of fever. The most notable finding was a reduced number of patients with fever compared to that expected (31 % ). This impacted study participant recruitment and will affect the feasibility of completing a larger phase III study.

description: We study synchronization of sinusoidally coupled phase oscillators on networks with modular structure and a large number of oscillators in each community. Of particular interest is the hierarchy of local and global synchrony, i.e., synchrony within and between communities, respectively. Using the recent ansatz of Ott and Antonsen, we find that the degree of local synchrony can be determined from a set of coupled low-dimensional equations. If the number of communities in the network is large, a low-dimensional description of global synchrony can be also found. Using these results, we study bifurcations between different types of synchrony. We find that, depending on the relative strength of local and global coupling, the transition to synchrony in the network can be mediated by local or global effects.

description: Geostatistical techniques and remote sensing are used in this study to help reduce the number of soil salinity samples needed for mapping soil salinity. Two datasets were collected in alfalfa and corn fields and satellite images with different spatial and spectral resolutions from Ikonos, Landsat, and Aster were acquired and processed. Generalized least squares (GLS) was used to regress the collected soil salinity samples with the selected bands; and ordinary kriging was used to krig the residuals of the GLS model. Variograms were used as indictors for using the proper number of samples needed for kriging in order to map soil salinity. The objectives of this study are: 1) to utilize the variograms to help reduce the number of samples needed for mapping soil salinity; 2) to compare different cover types (alfalfa and corn) as well as compare different satellite images in capturing the variation of soil salinity. The results of this study show that the variograms can be used as a good indicator to significantly reduce the number of samples needed for mapping soil salinity. It was determined that corn fields capture more variation in soil salinity than alfalfa fields. Among the different satellite images used, the IKONOS images performed the best.

description: With the increasing regularity of pandemics, global terrorism, and natural disasters, organizations seek strategic solutions that enable business continuity. Telework is one such solution; yet it is all but ignored by organizational decision makers as a viable, strategic option. This doctoral dissertation is composed of four essays that explore potential barriers to organizational telework adoption. The first essay is a quantitative study that reviews and meta-analyzes correlations from empirical studies to find that there is a positive relationship between telework and organizational outcomes. The second essay reviews publicly available reports to confirm the low level of telework adoption at the organizational level, followed by a review of the academic literature to classify the frames of reference captured and perpetuated by research which may be acting as a barrier. The third essay draws upon behavioural economics to empirically test framing effects on the managerial adoption decision. A new, potential barrier is identified as are specific changes to the decision frame that shift adoption preferences. The fourth essay replicates and extends the lab study of essay three, this time in the field with a sample of organizational decision makers. Findings are in line with the original study while extending knowledge through the identification and testing of a new frame of reference that shifts preferences in favour of adoption.
On the Market for Principles of Economics Textbooks: Innovation and Product Differentiation
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University
Year: 1988
Subjects: Economics

description: I have been asked to prepare a few remarks reflecting my views on the current state of principles of economics textbooks. It goes without saying that, given the plethora of textbooks available on the market, I have not read in detail all of them, and this is not the occasion to provide a detailed criticism of any single textbook. My remarks will, of necessity, be somewhat impressionistic, but they reflect impressions developed over years of discussing with colleagues at a large number of colleges and universities the problems presented by the modern American principles of economics textbook. I want to put forward two theses, as well as raise several unresolved questions and issues. The first thesis is that the market for principles textbooks provides a good example of one of the central paradigms of modern economics, that of monopolistic competition, and it reflects both the strengths and weaknesses that economic theory would have led us to expect to arise in such a market.

description: We will study the spectral problem related to the Laplace operator in a singularly perturbed periodic waveguide. The waveguide is a quasi-cylinder with contains periodic arrangement of inclusions. On the boundary of the waveguide we consider both Neumann and Dirichlet conditions. We will prove that provided the diameter of the inclusion is small enough in the spectrum of Laplacian opens spectral gaps, i.e. frequencies that does not propagate through the waveguide. The existence of the band gaps will verified using the asymptotic analysis of elliptic operators.

description: The valuation of the variance swaps for local Levy based stochastic volatility with delay (LLBSVD) is discussed in this thesis. We provide some analytical closed forms for the expectation of the realized variance for the LLBSVD. As applications of our analytical solutions, we fit our model to 10 years of S&P500 data (2000-01-01-2009-12-31) with variance gamma model and apply the obtained analytical solutions to price the variance swap.

description: Following blood, bone graft transplantation is the second most common tissue transplant. Although tissue engineering holds great potential to fulfill demands for better treatment outcomes, it remains technologically challenging to produce bone grafts with normal physiological properties. During skeletal development, endochondral ossification initiates long bone formation and fracture healing. In this study, I aimed to build an in-vitro biomimetic bioreactor to recapitulate physiological niches and processes essential for endochondral ossification to grow bone tissues with anatomical and mechanical properties similar to the native tissues. Here, I have built a prototype capable of generating a dynamic cultivation environment and producing an ivory-toned construct with a stiff texture. The engineered construct greatly resembles a hyaline cartilage model undergoing initial stages of endochondral ossification during skeletal development. In the future, a possible engineered vasculature system may be integrated into the existing bioreactor design to enhance further maturation of constructs to form compact bone.
Towards cloud-based anti-malware protection for desktop and mobile platforms

description: Malware is a persistent and growing problem that threatens the privacy and property of computer users. In recent years, this threat has spread to mobile devices such as smartphones and tablet computers. At the same time, the main method for combating malware, anti-virus software, has grown in size and complexity to the point where the resource demands imposed by these security systems have become increasingly notice­able. In an effort to create a more transparent security system, it is possible to move the scanning of malware from the host computer to a scanning service in the cloud. This relocation could offer the security of conventional host-based scanning, without the resource demands involved with running a fully host-based anti-virus system. This thesis shows that under the right circumstances, malware scanning services pro­vided remotely are capable of replacing host-based anti-malware systems on desktop computers, although such a cloud-based security system is better suited to protecting smartphone users from malicious applications. To that end, a system was developed that provides anti-malware security for desktop computers by making use of pre-existing web-based file scanning services for malware detection. This system was evaluated and found to have variable performance ranging from acceptable to very poor. The desktop scanning system was then augmented and adapted to serve as a mechanism for identify­ing malicious applications on Android smartphones. The evaluation of this latter system showed favorable results, and is effective as a mechanism for combating the growing mobile malware threat.
