How community dance leads to positive outcomes: A self-determination theory perspective
Authors: NORFIELD JENNIE , NORDIN-BATES SANNA
Published: January 2012

Little is known about how community dance influences well-being. Grounded in selfdetermination theory (SDT), this study examined the relationship between dancers' perceptions of the motivational climate, basic need satisfaction (competence, autonomy and relatedness) and motivation-related
variables (intrinsic motivation, enjoyment and perceived effort) in community dance. A total of 84 dancers (mean age=44.28 years, SD=20.04) regularly attending community dance groups in any style, completed a questionnaire addressing the targeted variables. Hierarchical multiple regression
analyses supported a model in which dancers' perceptions of a task climate positively predicted autonomy and relatedness satisfaction. In addition, a model in which dancers' intrinsic motivation, enjoyment and perceived effort were predicted by their perceptions of the motivational climate
and need satisfaction was partially supported. This study provides preliminary evidence as to the applicability of SDT to community dance and indicates the importance of promoting task-involving climates in order to foster positive experiences from community dance participation.
Trajektorienregelung von zeitkritischen Fahrmanövern
Authors: Werling Moritz , Gröll Lutz , Bretthauer Georg
Published: January 2012

Die Beherrschung dynamischer Verkehrsszenarien erfordert die Stabilisierung von zeitkritischen Fahrmanövern, wie dem Ausweichen beweglicher Hindernisse oder dem Einfädeln in fließenden Verkehr. Beim autonomen Fahren stoßen hierbei die bisher eingesetzten bahnbasierten Verfahren an ihre Grenzen. Das im Beitrag mittels exakter Ein-/Ausgangslinearisierung entworfene trajektorienbasierte Stabilisierungskonzept hingegen berücksichtigt die Zeit t während der Manöverdurchführung explizit, sodass bewegliche Hindernisse präzise umfahren werden können.
The possible options for the prevention of preeclampsia
Authors: Fodor Andrea , Győrffy András , Váradi Magdolna , Fülesdi Béla , Major Tamás
Published: January 2012

This review summarizes the possible options for the prevention of preeclampsia based on important factors of patomechanism. The effects of antioxidants have been described in numerous clinical researches based on the oxidative hypothesis. Another important factor is the change of nitric oxide activity. Nitric oxide donors are able to compensate the symptoms of preeclampsia. The inverse relationship between the calcium intake and gestational hypertension has been known for a long time. The calcium supplementation seems to be a good opportunity to prevent preeclampsia. With low molecular weight heparins we can intervene in the patomechanisms of preeclampsia by antithrombocyte effects, vasoactive properties and impact on throphoblast cell morphology and differentiation. Thrombocyte aggregation inhibitors were examined in number of studies because they reduced thromboxane mediated vasoconstriction and inhibited placental thrombosis. Several studies verify whether prophylaxis with low molecular weight heparins and low dose aspirin could improve pregnancy outcome in preeclampsia. Orv. Hetil., 2012, 153, 144–151.
Interactions of insulin and estrogen in the regulation of cell proliferation and carcinogenesis
Authors: Suba Zsuzsanna , Kásler Miklós
Published: January 2012

Equilibrium of sexual steroids and metabolic processes has close correlations. Insulin is a potent regulator of human sexual steroid hormone production and modulates their signals at receptor level. Insulin resistance and excessive insulin production provoke hyperandrogenism and estrogen deficiency in women resulting not only in anovulatory dysfunction but also a high risk for cardiovascular diseases and cancer. Physiologic functions of all female organs have higher estrogen demand as compared with men. In healthy women estrogen predominance against androgens is a favor in their reproductive period, which means a strong defense against insulin resistance and its complications. However, in postmenopausal cases the increasing prevalence of insulin resistance and type-2 diabetes associated with estrogen deficiency and androgen excess, result in a gender specific higher risk for precancerous lesions and cancer as compared with men. Estrogen has beneficial effect on the energy metabolism, glucose homeostasis and on the lipid metabolism of liver and of peripheral tissues as well. A moderate or severe decrease in serum estrogen level enhances the prevalence of insulin resistant states. In premenopausal women long or irregular menstrual cycles are predictors for the risk of insulin resistance and type-2 diabetes. Moreover, in postmenopausal estrogen deficient cases elevated fasting glucose, increased body weight and abdominal fat deposition are often observed progressively with age in correlation with an impaired glucose tolerance. In the rare cases of estrogen deficient men severe type-2 diabetes seems to be a characteristic complication. Upon becoming familiar with the cancer risk of insulin resistance and estrogen deficiency, there would be plenty of possibilities for primary cancer prevention. In patients with cancer the treatment of hormonal and metabolic disturbances may become effective adjuvant therapy. Orv. Hetil., 2012, 153, 125–136.

Representability and amalgamation for Heyting polyadic algebras
Authors: Ahmed Tarek
Published: January 2012

We prove that every (not necessarily locally finite) polyadic Heyting algebra of infinite dimension is representable in some concrete sense. We also show that this class has the super amalgamation property. As a byproduct we infer that a certain infinitary extension of predicate intuitionistic logic, or equivalently, the intuitionistic fragment of Keisler’s infinitary logics, is complete and enjoys the Craig interpolation property.
Homotopical complexity of 2D billiard orbits
Authors: Goswick Lee , Simányi Nándor
Published: January 2012

Traditionally, rotation numbers for toroidal billiard flows are defined as the limiting vectors of average displacements per time on trajectory segments. Naturally, these creatures live in the (commutative) vector space ℝn, if the toroidal billiard is given on the flatn-torus. The billiard trajectories, being curves, often getting very close to closed loops, quite naturally define elements of the fundamental group of the billiard table. The simplest non-trivial fundamental group obtained this way belongs to the classical Sinai billiard, i.e. the billiard flow on the 2-torus with a single, strictly convex obstacle (with smooth boundary) removed. This fundamental group is known to be the groupF2freely generated by two elements, which is a heavily noncommutative, hyperbolic group in Gromov’s sense. We define the homotopical rotation number and the homotopical rotation set for this model, and provide lower and upper estimates for the latter one, along with checking the validity of classically expected properties, like the density (in the homotopical rotation set) of the homotopical rotation numbers of periodic orbits.The natural habitat for these objects is the infinite cone erected upon the Cantor set Ends (F2) of all ŋds" of the hyperbolic groupF2. An element of Ends (F2) describes the direction in (the Cayley graph of) the groupF2in which the considered trajectory escapes to infinity, whereas the height functiont(t≧ 0) of the cone gives us the average speed at which this escape takes place.The main results of this paper claim that the orbits can only escape to infinity at a speed not exceeding\documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{upgreek} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage{bbm} \pagestyle{empty} \DeclareMathSizes{10}{9}{7}{6} \begin{document} $\sqrt 2 $ \end{document}, and any directione∈ Ends (F2) for the escape is feasible with any prescribed speeds, 0 ≦s≦\documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{upgreek} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage{bbm} \pagestyle{empty} \DeclareMathSizes{10}{9}{7}{6} \begin{document} $\sqrt 2 $ \end{document}/2.

Strength and stiffness of a cement-stabilised lateritic soil with granulated rubber addition
Authors: Chan Chee-Ming
Published: January 2012

Ground improvement via soil stabilisation has been widely applied and proven to be an effective countermeasure for development on problematic soils. The stabilisation procedure usually involves addition and thorough mixing of hydraulic binders with in situ soils, consequently transforming the soft materials into a stronger and stiffer stratum for load bearing. Nevertheless the method can also be adopted for reusing and strengthening clayey soils, such as laterite, for the construction of road foundations. Recycling and reuse of waste materials, such as granulated rubber processed from waste tyres, should be considered for developing alternative soil stabilisers. Each new combination of stabilising agents introduced needs to be carefully examined in terms of the stabilised material's enhanced properties, especially the strength and stiffness of the targeted soil, as different soil types are known to react differently with different stabilisers. This paper presents experimental test results of a lateritic soil (clayey sand) stabilised with 0–4% cement and 0–4% rubber chips or rubber shreds. In the study, unconfined compressive strength tests were complemented by elastic (i.e. P- and S-) wave velocity measurements. The corresponding strength and stiffness of the various mixes were analysed and discussed in this paper. Correlations between the parameters investigated were also established to shed light on the improved soil properties. Both strength and stiffness of the stabilised soil were found to be predominantly controlled by cement content, although higher rubber dosages were observed to increase the ductility of the stabilised material. Furthermore, the form of the rubber addition, as either chips or shreds, did not appear to have a significant effect on the response of the stabilised material. In short, results from the unconfined test series highlighted the potential of cement–rubber as an alternative stabilising agent for similar lateritic soils, specifically in terms of strength and stiffness improvement. Long-term durability of the stabilised material however, with relevance to exposure to the elements and various site conditions, needs to be addressed in follow-up investigations to ascertain the site applicability.
Stress and Mental Health Among Midlife and Older Gay-Identified Men
Authors: Wight Richard G. , LeBlanc Allen J. , de Vries Brian , Detels Roger
Published: January 2012

Objectives. We investigated associations between stress and mental health (positive affect, depressive symptoms) among HIV-negative and HIV-positive midlife and older gay-identified men, along with the mediating and moderating effects of mastery and emotional support. We also studied the mental health effects of same-sex marriage.

Methods. We obtained data from self-administered questionnaires completed in 2009 or 2010 by a subsample (n = 202; average age = 56.91 years; age range = 44–75 years) of participants in the University of California, Los Angeles component of the Multicenter AIDS Cohort Study, one of the largest and longest-running natural-history studies of HIV/AIDS in the United States.

Results. Both sexual minority stress (perceived gay-related stigma, excessive HIV bereavements) and aging-related stress (independence and fiscal concerns) appeared to have been detrimental to mental health. Sense of mastery partially mediated these associations. Being legally married was significantly protective net of all covariates, including having a domestic partner but not being married. Education, HIV status, and race/ethnicity had no significant effects.

Conclusions. Sexual minority and aging-related stress significantly affected the emotional lives of these men. Personal sense of mastery may help to sustain them as they age. We observed specific mental health benefits of same-sex legal marriage.
Temporal Trends in Incidence and Mortality Rates for Colorectal Cancer by Tumor Location: 1975–2007
Authors: Phipps Amanda I. , Scoggins John , Rossing Mary Anne , Li Christopher I. , Newcomb Polly A.
Published: January 2012

Objectives. We evaluated changes in colorectal cancer (CRC) incidence and mortality by anatomic site to assess the possible impact of CRC screening.

Methods. Using data from 9 Surveillance, Epidemiology, and End Results cancer registries, we estimated trends in 1975–2007 CRC incidence and 1985–2007 incidence-based mortality. We evaluated trends separately for proximal and distal CRC, overall and by stage, tumor site, and race.

Results. Between 1975 and 2007, 323 237 adults in the study area were diagnosed with CRC. For most tumor and population subgroups, incidence rates increased between 1975 and 1985 and subsequently declined markedly. Declines were most rapid between 1999 and 2007 and were greater for distal than proximal CRC. Declines in incidence were greater for White than Black adults and greatest for regional-stage disease. There was little difference in trends across subsites within the proximal and distal colorectum. Declines in incidence-based mortality mirrored those for incidence.

Conclusions. Recent declines in CRC incidence and mortality are greater for distal than proximal CRC. Differing trends across populations may reflect variations in screening prevalence; distinct trends by tumor characteristics likely reflect differences in screening efficacy.
Project-Based Housing First for Chronically Homeless Individuals With Alcohol Problems: Within-Subjects Analyses of 2-Year Alcohol Trajectories

Published: January 2012

Objectives. Two-year alcohol use trajectories were documented among residents in a project-based Housing First program. Project-based Housing First provides immediate, low-barrier, nonabstinence-based, permanent supportive housing to chronically homeless individuals within a single housing project. The study aim was to address concerns that nonabstinence-based housing may enable alcohol use.

Methods. A 2-year, within-subjects analysis was conducted among 95 chronically homeless individuals with alcohol problems who were allocated to project-based Housing First. Alcohol variables were assessed through self-report. Data on intervention exposure were extracted from agency records.

Results. Multilevel growth models indicated significant within-subjects decreases across alcohol use outcomes over the study period. Intervention exposure, represented by months spent in housing, consistently predicted additional decreases in alcohol use outcomes.

Conclusions. Findings did not support the enabling hypothesis. Although the project-based Housing First program did not require abstinence or treatment attendance, participants decreased their alcohol use and alcohol-related problems as a function of time and intervention exposure.
Adolescent Health and Harassment Based on Discriminatory Bias
Authors: Russell Stephen T. , Sinclair Katerina O. , Poteat V. Paul , Koenig Brian W.
Published: January 2012

Is harassment based on personal characteristics such as race/ethnicity, sexual orientation, religion, or disability more detrimental than general harassment? In 2 large population-based studies of adolescents, more than one third of those harassed reported bias-based school harassment. Both studies show that bias-based harassment is more strongly associated with compromised health than general harassment. Research on harassment among youths rarely examines the underlying cause. Attention to bias or prejudice in harassment and bullying should be incorporated into programs and policies for young people.
Community Epidemiology of Risk and Adolescent Substance Use: Practical Questions for Enhancing Prevention
Authors: Feinberg Mark E.
Published: January 2012

To promote an effective approach to prevention, the community diagnosis model helps communities systematically assess and prioritize risk factors to guide the selection of preventive interventions. This increasingly widely used model relies primarily on individual-level research that links risk and protective factors to substance use outcomes. I discuss common assumptions in the translation of such research concerning the definition of risk factor elevation; the equivalence, independence, and stability of relations between risk factors and problem behaviors; and community differences in risk factors and risk factor–problem behavior relations. Exploring these assumptions could improve understanding of the relations of risk factors and substance use within and across communities and enhance the efficacy of the community diagnosis model. This approach can also be applied to other areas of public health where individual and community levels of risk and outcomes intersect.
Design and construction of a low capacity pump-less absorption system
Authors: Monsef Hamed , Zadegan Naghash , Javaherdeh Koroush
Published: January 2012

In this investigation, a low capacity absorption system has been designed and
constructed where the mechanical pump has been replaced with a bubble pump,
reducing the cost and eliminating the electrical power. Initially, a test rig
bubble pump has been built with a single Pyrex tube to test the effect of
different parameters on pumping flow rate. An absorption refrigeration system
with a capacity of 2.5 kW has been designed and constructed. Results have
shown that a bubble pump with five horizontal tubes with 2.5 mm diameter and
submergence ratio of 0.4 has the best performance for this low capacity
absorption refrigeration system. The COP of this structure was about 0.51 and
mathematical modeling shows that increasing the solution concentration at
generator outlet decreases the COP of the system.
Citing in Matica srpska social science quarterly in 2010: Empirical analysis as a contribution for founding scientometrics in Serbia
Authors: Bukvic Rajko
Published: January 2012

In this paper is given an empirical analysis of the sources and the citing
quality in the example of the Matica Srpska Social Science Quarterly in 2010.
After the methodological notes, in the first part of the paper was considered
the structure of citings, according to the informal classification (books,
newspaper articles, proceedings papers, statistical sources and so on). Then,
due to its importance, the citing structure of newspaper articles has been
presented separately. In the second part of the paper special attention was
drawn to the quality and reliability of citings in analyzed articles, where
numerous flaws and deficiencies were pointed out. Those flaws relativize
significantly the construction and use of the appropriate indicators for
further scientometric analysis.
Studies of technology in prehistoric archaeology
Authors: Vitezovic Selena
Published: January 2012

Technology studies have always been the most important focus of archaeology,
as a science which analyzes human past through the study of material culture.
To say that something is technological in archaeology, means to put the
concept of technology in the centre of theoretical studies, and to study not
only the form of the object, but also the entire sequence of technological
factors, from raw material choice, mode of use, up to the reasons for
abandonment. The concept of technology in anthropology and archaeology is
based on the original meaning of the word ????? in ancient Greek, meaning the
skill, i. e., to study how something is being done. Such a concept of
technology as a skill or mode of doing something was for the first time
outlined by the French anthropologist Marcel Mauss, whose starting point was
that every technological statement was at the same time social or cultural
statement and that technological choices have social foundations. Pierre
Lemonnier further developed the anthropology of technology, focusing on the
question of technological choices, as well as numerous other anthropologists.
In archaeology, the most important contribution to the study of technology
was the work of Andr? Leroi-Gourhan, who created the concept of cha?ne
op?ratoire, as an analytical tool for studying the mode of creating, using
and discarding an artefact, starting with raw material acquisition, mode of
manufacture, final form, use (including caching, breaking and repairing) up
to the final discarding. It is not only about reconstructing the algorithmic
sequence of operations in creating one object, but it is a complex analysis
of operational chain within one society which includes the analysis of
technological choices. The analyses of technologies today include a variety
of different approaches, most of them with emphasis on the cultural and
social aspects of technology. The analysis of bone industry in the Early and
Middle Neolithic in central Balkans (Starcevo culture), which included not
only final objects, but also manufacture debris and semi-finished products,
revealed a well developed industry, with a high level of technological
knowledge on the properties of raw materials, skillful manufacture, well
organized production, as well as possibility of a certain degree of
specialization on the micro and macro level (within one settlement and within
a group of settlements). Both raw material choices and manufacturing
techniques, as well as the final forms, demonstrated a high standardization
level. Also certain symbolic value was attributed to some raw materials, and
there is a possibility that skill itself was valued. Further analyses of
multiple technologies will help in reconstructing the organization of
production, social and economic aspects in Neolithic societies, as well as
the role of technology in everyday and ritual life.
Islamic mysticism - sufism
Authors: Novakovic Dragan
Published: January 2012

Basic concepts of Sufism are introduced along with pointing out that the
cause of occurrence of that original learning should be sought in gradual
distancing of the Islamic state and its leaders from the great moral ideals
and value system set by the Prophet Mohammed and the first caliphs. The
established periodization starts from the classical period dominated by
excessive influence of some scholars and the tendency of respecting local
traditions, continues with the medieval period marked by systematization and
achieving the peak of Sufi thought through acting of a number of great
mystics and ends with the modern period characterized by its prevalence and
enormous global impact, adapting to constantly changing conditions and
efforts for giving an adequate response to the challenges of colonialism,
which inevitably led to gradual weakening of Sufism. Overlapping between
mysticism, Hellenistic philosophy and other religious systems is also pointed
out, as an inexhaustible source of new, original and creative theological
syntheses, that significantly dynamized the already established Islamic
doctrine prone to repeating fixed patterns, as well as a great contribution
of Sufism to the spread of Islam in different parts of the world.
Magic roots of the aesthetic in art and technicity
Authors: Cuckovic Aleksandar
Published: January 2012

In order to respond to the challenges that nature placed in front of him, man
became more and more independent, and his relationship to the world grew more
and more mediated. On quitting experiencing himself in the magic unity with
the world, he invented the practices of technicity and religion, and, later,
the one of art. In technicity, the objective aspect of the mediation of the
world has been emphasized, and in the religion the subjective one. However,
nostalgia for the lost magical unity would never cease to determine not only
these, but all of the future practices as well. In that light, the very
important integration of technical and aesthetic practice should be
understood, the practice from which it has been expected to compensate the
separation and the fragmentation of technical objects by their aesthetic
networking and their technical reproduction.

The paper presents the results of quantitative and qualitative content
analysis of the six most influential daily newspapers in Serbia with a focus
on writing about topics that are directly and indirectly related to human
rights. It was noted that the selected media content was presented as
internal - political thing especially when the question of State
responsibility and the measures that have been undertaken by the State were
raised, or when the subject of activity of state institutions was questioned.
Most often quoted were representatives of the government as centers of
political power, though members of marginalized groups were also not absent.
The journalists showed sensitivity to marginalized actors of social practice.
Clear Cell Sarcoma of Kidney: Morphoproteomic Analysis Reveals Genomic Correlates and Therapeutic Options
Authors: Dhamne Sagar , Brown Robert E. , Covinsky Michael , Dhamne Chetan , Eldin Karen , Tatevian Nina
Published: January 2012

We used the morphoproteomic approach to analyze clear cell sarcoma of kidney (CCSK), a rare pediatric renal tumor, for which the exact pathogenesis and reliable diagnostic markers remain inexplicable. The tumor, currently being treated with chemotherapy and radiation therapy before or after radical nephrectomy, has demonstrated improved survival rates after introduction of doxorubicin. Three cases of CCSK were studied. We attempted to decipher the possible pathological mechanisms involved in CCSK and to explore the therapeutic targets and plausible less-toxic chemotherapeutic agents. We propose that eye lin D1 may be a central molecule in the pathogenesis of CCSK, driven mainly by the sonic hedgehog and the nuclear factor–kappa B pathways and secondarily by the mammalian target of rapamycin complex mTORC2/PI3K/Akt pathway, heat shock protein 90, and possibly phospholipase D1. Inclusion of relatively less toxic but effective therapies in the form of statins, 13- cis retinoic acid, curcumin, and 17-AAG in the combinatorial treatment strategies, which can target the involved subcellular pathways, may be considered.

Development of an in Vitro Potency Assay for Anti-anthrax Lethal Toxin Neutralizing Antibodies
Authors: Whiting Gail , Baker Michael , Rijpkema Sjoerd
Published: January 2012

Lethal toxin (LT) of Bacillus anthracis reduces the production of a number of inflammatory mediators, including transcription factors, chemokines and cytokines in various human cell lines, leading to down-regulation of the host inflammatory response. Previously we showed that the reduction of interleukin-8 (IL-8) is a sensitive marker of LT-mediated intoxication in human neutrophil-like NB-4 cells and that IL-8 levels are restored to normality when therapeutic monoclonal antibodies (mAb) with toxin-neutralising (TN) activity are added. We used this information to develop cell-based assays that examine the effects of TN therapeutic mAbs designed to treat LT intoxication and here we extend these findings. We present an in vitro assay based on human endothelial cell line HUVEC jr2, which measures the TN activity of therapeutic anti-LT mAbs using IL-8 as a marker for intoxication. HUVEC jr2 cells have the advantage over NB-4 cells that they are adherent, do not require a differentiation step and can be used in a microtitre plate format and therefore can facilitate high throughput analysis. This human cell-based assay provides a valid alternative to the mouse macrophage assay as it is a more biologically relevant model of the effects of toxin-neutralising antibodies in human infection.
Changes in Organizational Learning and Leadership Influenced by Technology

Local community leaders know what is needed in their communities. Interest in multilateral leadership is growing as communities aspire to more local control. This type of leadership employs structures and tools that benefit the collective good. This chapter presents five tenets of leadership that exemplify that focus on local control: transformation, communication, collaboration, planning, and integrity. A case study illustrates how these tenets have been applied in a real-world setting. These tenets are the foundation for a vision of leadership centered in the local community.
Leading Pedagogical Change with Innovative Web Tools and Social Media
Authors: McLoughlin Catherine
Published: January 2012

Today, in a globalised, digital world, there are significant challenges to be faced in the adoption and integration of emerging social media to support learning. Millennial students have grown up in technology-saturated environments with the Internet, mobile phones, video on demand, and personal computers. Teacher and educators must therefore know their students, and cater to their diverse needs. Educational institutions in the 21st century must learn how to adopt social software tools and apply sound pedagogical strategies in order to add value to existing practices and to enhance the learning process. Information Technology both supplements and enhances learning and student engagement by providing access to global learning communities and rich resources. Educational leaders need to be conversant with the technology, able to lead by example, and capable of creating authentic contexts and environments for learning. The contemporary media rich society of today demands teachers be ready to grapple with the significant pedagogic, cultural, and social changes associated with technological innovation.

Published: January 2012

In this chapter the authors evaluate a new and promising solution to the problem of power consumption based on “optimum gate biasing.” This technique consists in tracking the MOS operating region wherein the third derivation of drain current is zero. The method leads to a significant IIP3 improvement; however, the sensitivity to process drifts requires the use of a specific bias circuit to track the optimum biasing condition.
Simulation Techniques for Improving Fabrication Yield of RF-CMOS ICs
Authors: Herrera Amparo
Published: January 2012

One of the industry sectors with the largest revenue in the telecommunication field is the wireless communications field. Wireless operators compete for being the first to place their products in the market to obtain the highest revenues. Moreover, they try to offer products that fulfill the user demands in terms of price, battery life, and product quality. All these requirements must be also fulfilled by the designer of the MMIC (Microwave Monolithic Integrated Circuits) circuits that will be used in those wireless terminals, achieving a reliable design, with high performance, low cost, and if possible, in one or two foundry iterations so as to bring the product out to the market as soon as possible. Silicon based technologies are the lowest cost. The demand to use them is simply based on that fact, but their usage in these applications is limited by the ease of use for the designer, in particular, by the lack of adequate simulation models. These technologies don’t include some essential components for the design of RF circuits, which leads to measurement results quite different from those simulated. On the other hand, GaAs based technologies, more mature in the RF and microwave field, provide very accurate models, as well as additional tools to verify the design reliability (yield and sensitivity analysis), allowing good results often with only one foundry iteration. The deep study of the problems presented when designing Si-based RF circuits will convince the reader of the need to use special tools as electromagnetic simulation or coo simulation to prevent it. The chapter provides different simulation techniques that help the designer to obtain better designs with a lower cost, as foundry iterations are reduced.
RF-MEMS Based Oscillators
Authors: Nordin Anis Nurashikin
Published: January 2012

Today’s high-tech consumer market demand complex, portable personal wireless consumer devices that are low-cost and have small sizes. Creative methods of combining mature integrated circuit (IC) fabrication techniques with innovative radio-frequency micro-electro-mechanical systems (RF-MEMS) devices has given birth to wireless transceiver components, which operate at higher frequencies but are manufactured at the low-cost of standard ICs. Oscillators, RF bandpass filters, and low noise amplifiers are the most critical and important modules of any wireless transceiver. Their individual characteristics determine the overall performance of a transceiver. This chapter illustrates RF-oscillators that utilize MEMS devices such as resonators, varactors, and inductors for frequency generation. Emphasis will be given on state of the art RF-MEMS components such as film bulk acoustic wave, surface acoustic wave, flexural mode resonators, lateral and vertical varactors, and solenoid and planar inductors. The advantages and disadvantages of each device structure are described, with reference to the most recent work published in the field.

Published: January 2012

In this chapter, the main aspects of the design of baseband hardware modules are addressed. Special attention is given to word-length optimization, implementation, and validation tasks. As a case study, the design of an equalizer for a 4G MIMO receiver is addressed. The equalizer is part of a communication system able to handle up to 32 users and provide transmission bit-rates up to 125 Mbps. The word-length optimization process will be explained first, as well as techniques to reduce computation times. Then, the case study will be presented and analyzed, and the different tasks and tools required for its implementation will be explained. FPGAs are selected as the target implementation technology due to their interest from the DSP community.
The Effects of Cyberbullying on Children's School Adjustment
Authors: Betts Lucy R. , Houston James E.
Published: January 2012

Bullying is commonplace in many schools. For many it is an every-day occurrence with eight out of ten children reporting that they have been the victim of bullying in the previous month (Swayer, Bradshaw, & Brennan, 2008) and technology is increasingly being used as a medium to victimize (Dehue, Bolman, & Vollnick, 2008). This chapter will begin by providing a brief overview of bullying behavior and then discuss the differences between cyberbullying and more traditional forms of bullying. Prevalence rates from a range of studies will be presented and discussed. The chapter will then discuss the consequences of experiencing cyberbullying for children’s psychosocial and school adjustment and discuss how cyberbullying may need to be considered by researchers and practitioners with the increase in interactive learning. Finally, the chapter will discuss strategies to reduce children’s experiences of bullying, including some that make use of interactive learning.

The authors listened to the industries. They were told to incorporate soft skills within their layouts, and therefore, they introduced project-based approaches in which students solved real problems coupled with real environmental parameters.
Risk Management and Business Processes Reengineering, Success Drivers for ERP Projects
Authors: Agha Hussam Eldin I.
Published: January 2012

By using a case study example and focusing on the implementation phase, this chapter presents and emphasises the validity of specific risk management model. Briefly, an overview of another two ERP projects risk management’s models will be provided; the first model deals with ERP as technology where risks are managed in accordance to Information Technology and Information System (IT & IS) projects governance. The second model considers the integrated and interdisciplinary nature of ERP systems and introduces the term “ERP Governance” as a model that demands balance between IT and business governance. The third model, while similar to the second, relies heavily on best-practises and assessment frameworks from the industry. Throughout this chapter, the author explores this model, its importance, and application in contexts similar in nature to those found in the hierarchically structured intergovernmental organizations. Finally, the author concludes that embedding risk management best practices into the organization culture and business processes can positively influence the success of ERP system implementation. In other words, earlier adoption of risk management best practices for ERP system implementation will help both business & projects to meet their intended objectives and thus positively influence the success of ERP projects by ensuring that prescribed goals are met.
Contemporary Reporting Practices Regarding Covariance-Based SEM with a Lens on EQS
Authors: Edgington Theresa M. , Bentler Peter M.
Published: January 2012

Structural Equation Modeling (SEM) continues to grow in use as an important research analysis tool in Information Systems research. While evaluating SEM results and interpreting them depends on a variety of reported details, SEM results continue to be reported in an inconsistent manner. Key reporting elements are discussed with regard to contemporary practices which can serve as a guide for future submissions and reviewing. This chapter contributes to the literature by providing an overview of important considerations in reporting results from covariance-based structural equation modeling execution and analysis. It incorporates models and other examples of EQS, one of the leading SEM software applications. While EQS is increasingly used by IS researchers, exemplars of its code and output have not been well published within the IS community, overly complicating the reviewing process for these papers.

The primary aim of this chapter is to outline a potentially powerful framework for the combination of research approaches utilizing the Grounded Theory coding mechanism for Case Study, and Focus Groups data analysis. A secondary aim of this chapter is to provide a roadmap for such a usage by way of an example research project. The context for this project is the need to study and evaluate the actual practice of software development processes in real world commercial settings of software companies, which utilized both case study and focus group techniques. This research found that grounded theory coding strategies are a suitable and powerful data analysis mechanism to explore case study and focus group data.
ISMS Building for SMEs through the Reuse of Knowledge
Authors: Sánchez Luís Enrique , Santos-Olmo Antonio , Fernandez-Medina Eduardo , Piattini Mario
Published: January 2012

The information society is increasingly more dependent upon Information Security Management Systems (ISMSs), and the availability of these systems has become crucial to the evolution of Small and Medium-size Enterprises (SMEs). However, this type of companies requires ISMSs which have been adapted to their specific characteristics, and these systems must be optimized from the point of view of the resources necessary to deploy and maintain them. Over the last 10 years, the authors have obtained considerable experience in the establishment of ISMSs, and during this time, they have observed that the structure and characteristics of SMEs as regards security management are frequently very similar (since they can all be grouped by business size and sector), thus signifying that it is possible to construct patterns for ISMSs that can be reused and refined. In this chapter, the authors present the strategy that they have designed to manage and reuse security information in information system security management. This strategy is framed within a methodology designed for integral security management and its information systems maturity, denominated as “Methodology for Security Management and Maturity in Small and Medium-size Enterprises (MSM2-SME),” and it is defined in a reusable model called “Reusable Pattern for Security Management (RPSM),” which systematically defines, manages, and reuses the aforementioned methodology through a sub-process denominated as “Generation of Security Management Patterns (GSMP).” This model is currently being applied in real cases, and is thus constantly improving.
Surveillance Communities of Practice
Authors: Goldschmidt Peter
Published: January 2012

This discussion focuses primarily on supporting communities of practice tasked with compliance monitoring in complex environments. Here, the decision makers, as members of the surveillance community of practice, may be confronted with rapidly changing information, and the solution or solutions may be required rapidly at a low cost. In these cases, fully automated monitoring or surveillance systems are limited in their utility because of dynamic contexts and temporal and spatial variations. Managing these limitations typically requires human judgement to assess the results of these monitoring systems. Other reasons for requiring human judgement include a need for the surveillance results to be verified and assured with substantiating evidence, and the delegation of control and responsibility when actioning remedial responses to generated alerts and alarms. Surveillance Information Systems performance depends on reducing the decision time for remedial action by verifying alarms and generating actionable indicators, in context. This chapter discusses support and assurance of surveillance monitoring and compliance verification knowledge management of surveillance results. The aim is to support information assurance real time alarm identification and verification, assurance and management decision making by tracking the parameters monitored by the existing information assurance monitoring infrastructure and operating work systems, and using that data/knowledge to create useful and actionable information. The goal is to reduce the (information assurance remedial action) time to decision to enable accurate and rapid operational execution.
