Cancelable biometric based key generation for symmetric cryptography

Most of the existing algorithms of key generation for symmetric cryptographic use a private key having size of 128, 192 or 256 bits. These long keys are difficult to remember, hence, stored in smart card; tamper-resistant token, etc. or password based authentication method is used to control the access of cryptographic key. But these user selected passwords sometimes lost or guessed by dictionary attacks. Moreover, in symmetric cryptography, sender and receiver must have the same secret key and the key must be secured which leads to another threat of security. As a substitute to this, generation of cryptographic key using the biometric traits of both sender and receiver during the sessions of communication can be a possible solution of the above discussed key management problem. But the problem with biometrics is that once it gets compromised it cannot be reused. As a proficient solution for cancelling and reissuing biometric template cancelable biometrics has been proposed. The present work proposed to generate 128 bit symmetric key from cancelable fingerprint templates of both communicating parties. The current approach confirms the privacy of fingerprints by one way transformation of original template into cancelable one as well as resolves the difficulty of key storage and key distribution as the key is not sent to the recipient and is also not saved anywhere.
A novel technique for ZigBee coordinator failure recovery and its impact on timing synchronization

In mission critical wireless sensor networks (WSNs) accurate timestamping of the occurrence of events measured by the sensor nodes is often required together with a high degree of reliability. While precise timestamping requires synchronization of the sensor nodes, reliability is obtained by adding redundancy in all potential single point of failure nodes. In this paper, we focus on a ZigBee-based WSN using two personal area network (PAN) coordinators with different PAN identifiers (IDs) and, for this configuration, we propose a solution where if the primary PAN coordinator goes down, connections are transferred to the other by changing the PAN ID of the nodes. Our proposed solution provides significant gains in terms of recovery speed and timing synchronization accuracy in comparison to a solution that is proposed in the literature.
Side effects of aminoglycosides on the kidney, ear and balance in cystic fibrosis

Aminoglycoside antibiotics are a central component of the treatment of pulmonary exacerbations of cystic fibrosis (CF) and slow the decline in lung function which ultimately causes the death of most patients. The prognosis of CF has improved, and thus side effects of treatments have become increasingly important. Observational studies suggest that the morbidity from side effects of aminoglycosides is disturbingly common, and that aggressive treatment may lead to more side effects. This review of the current literature on side effects of aminoglycosides considers the pathophysiological mechanisms, epidemiology and risk factors, investigation of side effects and preventative strategies. Treatments which have shown early promise are identified and areas of future research are discussed.
The social relations model: an integrative method for personality research

As outlined by Snyder and Ickes (1985), the study of personality can be undertaken using one of three research approaches dispositional, situational, and interactive We show how the Social Relations Model provides an integrative method to estimate simultaneously dispositional, situational, and interactive effects Reviewed are component approaches to the study of personality The Social Relations Model is shown to be a component model (a special case of generalizability theory) applied in a social interaction context In the model, dispositional, situational, and interactive effects are termed actor, partner, and relationship effects, respectively The Social Relations Model can be used to answer a number of important issues in personality research The model can be used to assess reliability, measure the validity of self-ratings, and validate self-report inventories The model requires special designs in winch each person interacts with multiple partners Empirical examples are presented in which social anxiety, sex role inventories, and self-disclosure are studied
Assessment of Exposure to Polycyclic Aromatic Hydrocarbons in Police in Florence, Italy, through Personal Air Sampling and Biological Monitoring of the Urinary Metabolite 1-Hydroxypyrene

Abstract In this study, the authors evaluated exposure to airborne polycyclic aromatic hydrocarbons (PAHs) in workers exposed to exhaust gas from cars, and they assessed the efficiency of urinary 1-hydroxypyrene as an indicator of exposure to pyrene and PAHs. The authors selected 2 groups of police who worked in 2 areas in the city of Florence: 1 group was highly exposed to high-density traffic emissions during the winter and summer of 1997, and the 2nd group experienced low exposure to traffic emissions during the same period. Ambient monitoring was achieved with personal sampling of airborne PAHs during each workshift. Eight hydrocarbons were used as indicators of pollution caused by PAHs (e.g., pyrene, benzo[a]pyrene, benzo[a]anthracene, dibenzo[a,h]anthracene). Biological monitoring was performed through dosing of 1-hydroxypyrene (pyrene metabolite) in urine samples taken at the end of each workshift. The ambient monitoring revealed that PAH concentrations were influenced by both season of sampling and varying intensities of traffic in the different areas. The median concentration of benzo[a]pyrene in winter was twice as high in the high-density traffic area as in the low-density traffic area (i.e., 4.1 ng/m3 versus 1.8 ng/m3). In summer, the high-density traffic area experienced benzo[a]pyrene concentrations that were 6 times higher than in the low-density traffic area (i.e., 1.2 ng/m3 versus 0.2 ng/m3). Benzo[a]pyrene was also correlated highly (r s = .92, p < .0001) with the mixture of total PAHs analyzed, thus confirming its function as a good indicator of exposure to PAHs in an urban environment. Levels of urinary 1-hydroxypyrene appeared to be generally influenced by the intensity of traffic, especially during the winter (i.e., median value in winter was 199.2 ng/gm creatinine in the high-density traffic area and 120.5 ng/gm creatinine in the low-density traffic area). An analysis of the general data revealed that 1-hydroxypyrene was, to some degree, related to pyrene, benzo[a]pyrene, and airborne total PAHs, whereas analysis of separate data for the area and the season revealed an emergence of a closer correlation during the winter in the high-traffic area. Therefore, 1-hydroxypyrene can be considered a good biological indicator of exposure to airborne PAHs in the urban environment, especially in winter and in high-density traffic areas.
Intervening in Stress, Attachment and Challenging Behaviour. Effects in Children with Multiple Disabilities

Sommige kinderen met ernstige beperkingen groeien op met zoveel wisselende opvoeders, communicatieve beperkingen, en soms inadequate zorg, dat ze geen gelegenheid krijgen om gehechtheidsrelaties te ontwikkelen. Deze kinderen worden naarmate ze ouder worden steeds moeilijker te bereiken. In hun sociale isolement doet de goedof afkeuring van hun opvoeders en verzorgers hen nog maar weinig, wat het moeilijk maakt hun gedrag bij te sturen. Hun isolement en achterstand worden daardoor alleen nog maar vergroot. De vraag is wat een wending teweeg kan brengen in de ontwikkeling van deze kinderen. In dit onderzoek stond psychotherapie centraal, meer in het bijzonder een ‘Integratieve Therapie voor Gehechtheid en Gedrag (ITGG)’, als middel om aan te tonen dat ondanks de slechte start van deze kinderen, het opbouwen van een gehechtheidsrelatie een positief verschil kan maken. Eerst is onderzocht of kinderen met een geschiedenis van pathogene zorg, met een visuele en ernstig verstandelijke beperking en ernstige gedragsproblemen een gehechtheidsrelatie met de therapeut kunnen opbouwen. Vervolgens is onderzocht wat het effect is van ITGG op het gedrag van het kind.
Detecting malicious JavaScript

The increased use of the World Wide Web and JavaScript as a scripting language for Web pages have made JavaScript a popular attack vector for infecting users' machines with malware. Additionally, attackers often obfuscate their code to avoid detection, which heightens the challenge and complexity of automated defense systems. We present two analyses of malicious scripts and suggest how they could be extended into intrusion detection systems. For our analyses we use a sample of deobfuscated malicious and benign scripts collected from actual Web sites. First, using our malicious sample, we perform a manual analysis of attack signatures, identifying four distinct categories of attacks. Second, we use existing research software to analyze certain function calls made by the malicious and benign scripts, and compare the resulting distributions of function calls. Then we perform a classification analysis using logistic regression to propose an approach for a host-based intrusion detection system.
Non-regenerative two-hop wiretap channels using interference neutralization

In this paper, we analyze the achievable secrecy rates in the two-hop wiretap channel with four nodes, where the transmitter and the receiver have multiple antennas while the relay and the eavesdropper have only a single antenna each. The relay is operating in amplify-and-forward mode and all the channels between the nodes are known perfectly by the transmitter. We discuss different transmission and protection schemes like artificial noise (AN). Furthermore, we introduce interference neutralization (IN) as a new protection scheme. We compare the different schemes regarding the high-SNR slope and the high-SNR power offset and illustrate the performance by simulation results. It is shown analytically as well as by numerical simulations that the high SNR performance of the proposed IN scheme is better than the one of AN.
Factors Influencing Alcohol Use Among Sexual Minority Women in a Non-Urban Community: A Mixed Methods Study

The present study used a mixed methods design to explore factors influencing alcohol use among sexual minority (lesbian, bisexual, queer, and same-sex attracted) women in a non-urban community. Semi-structured individual interviews were conducted with 15 self-identified sexual minority women regarding the physical, social, and emotional context of two recent incidents of alcohol use. To compliment the interview responses, participants also completed the Lesbian Internalized Homophobia Scale and Psychological Sense of LGBT Community Scale. Qualitative content analysis was used to analyze the interview data, revealing patterns of alcohol use and influences on drinking across various contexts. The majority of reported incidents met the criteria for hazardous drinking and occurred in public LGBTQ settings. The top reported influences on alcohol use were to decrease anxiety, ease social interaction, enhance enjoyment and fun, and peer pressure to fit in. Patterns across drinking settings, influences, internalized heterosexism, and psychological sense of community are outlined. Implications for practice, research, and communities are discussed.
Searching the Web: general and scientific information access

The World Wide Web has revolutionized the way that people access information, and has opened up new possibilities in areas such as digital libraries, general and scientific information dissemination and retrieval, education, commerce, entertainment, government and health care. There are many avenues for improvement of the Web, for example in the areas of locating and organizing information. Current techniques for access to both general and scientific information on the Web provide much room for improvement, search engines do not provide comprehensive indices of the Web and have difficulty in accurately ranking the relevance of results. Scientific information on the Web is very disorganized. We discuss the effectiveness of Web search engines, including results that show that the major Web search engines cover only a fraction of the "publicly indexable Web". Current research into improved searching of the Web is discussed, including new techniques for ranking the relevance of results, and new techniques in metasearch that can improve the efficiency and effectiveness of Web search. The creation of digital libraries incorporating autonomous citation indexing is discussed for improved access to scientific information on the Web.
Stress and social work lecturers : dreaming spires, ivory towers or besieged in concrete blocks

The focus of this article is upon the impact of environmental stress and demands on social work lecturers. Stress is experienced as an individual phenomenon by social work lecturers, but is considered within a structural and an institutional context. In particular, it is examined against the background of recent developments in higher education generally, such as the Higher Education Funding Council quality assessment visits and the research assessment exercise. In recent years, there have been significant alterations to the shape of social work education with the establishment of the DipSW, its modification and review, and the development of Post Qualifying Consortia. Classic features of stress have been imposed on social work lecturers particularly by their institutions and other organisations, leading to a lack of control, an imbalance of demands over resources, role overload and role conflict. These stressors impact negatively upon interpersonal relationships with colleagues and students. Some suggest.
Secularism and Theism: A Problem of Rationality

Problem statement: A belief prevails today that pluralist liberal societies and genuine religious belief are incompatible. Until this belief is overcome it is unlikely that progress can be made toward dialogue between liberal pluralists, who pride themselves on their open-mindedness and rationality, and religious conservatives in America and theocrats elsewhere who esteem their devotion equally highly. Approach: Compare the rationality of “paradigm shifts” and that of religious conversion. Results: There was no difference in rationality between scientific progress when understood as a âparadigm shiftâ and that between conversion from theism to atheism or vice versa. Conclusion: Neither secularists nor theists were justified in their belief that liberalism and theism are incompatible. Pluralities of beliefs are all equally justifiable in terms of reason.
Bad StartS and Better finiSheS: attriButional retraining and initial performanCe in Competitive aChievement SettingS

Transitions to new achievement settings are often accompanied by unfamiliar learning conditions wherein individuals experience unanticipated failures and engage in dysfunctional explanatory thinking. To counter these developments, attributional retraining (AR) was presented to 457 first-year students following an initial test in a two-semester course. A Semester 1 AR treatment (no, yes) and initial-test-performance (low, average, high) 2 × 3 quasi-experimental design was used to assess Semester 2 attributions, emotions, and performance outcomes. AR encouraged all students to endorse controllable attributions and de-emphasize uncontrollable attributions in explaining achievement outcomes in Semester 2. For low- and average-initial-performance students, AR improved subsequent in-class tests, final course grades, and first-year GPAs. Higher initial-test-performance was related to positive emotions and better achievement in Semester 2. The discussion focused on the implications of AR for attributional thinkin.
Hydrodynamic properties of rigid macromolecules composed of ellipsoidal and cylindrical subunits.

A procedure is devised for the calculation of hydrodynamic properties of rigid macromolecules composed subunits that are modeled as ellipsoids of revolution and cylinders. Owing to the axial symmetry of these shapes, smooth shell models can be constructured for the subunit structure. The bead shell model so constructed is employed for the calculation of the properties. A computer program, HYDROSUB, has been written implementing both the model building and the hydrodynamic calculation. A detailed example of the use of this methodology is presented for the case of the solution properties of the human antibody molecule immunoglobulin G3 (IgG3). Finally, hints are given on other uses and applications of the procedure.
Impact of a national programme of professional development in science education

Evaluation of large‐scale professional development programmes in a cost‐effective but detailed manner presents challenges. Much of the research evidence on the effectiveness of professional development in science education has been the result of small‐scale studies that use clustered or stratified sampling methods. Using the evidence collected from the national Network of 10 Science Learning Centres in the UK, this research examines the nature and extent of change on a national scale from large numbers of teachers’ involvement in professional development courses. The network administers a common system of ‘embedded evaluation’, which integrates completion of evaluation forms in the training process, thus making a cross‐network study of impact possible. The research employed a triangulated approach of analysis of reported impact from different sources including impact toolkit forms, interviews with participants, a survey of their line managers and evidence from course leaders. The research shows that besides the direct impact on teachers’ own classroom practice, there is evidence of wider change involving other teachers and on whole school practice. Use of an evaluation toolkit embedded in the professional development course is regarded as a key process in supporting change and monitoring progress.
Chapter 7: Family Influences on Cognitive Development and School Achievement

The notion of family influence on cognitive development and school achievement has great intuitive appeal and has been popularized in educational practice. Educators now widely acknowledge the importance of the family (Leichter, 1974), as they have during earlier historical periods (Clarke-Stewart, 1978b). Because of the importance attributed to the family, the specific means through which the family might influence intellectual development need to be delineated. Studies of the family's influence are especially timely because families are undergoing change, such as in the increased number of one-parent families, the increased participation of fathers in child rearing, and the increased participation of mothers in the work force. This chapter discusses some of the ways in which families may influence children's cognitive development and school achievement. Environmental and biological factors that have been prominent in explanations of the family's influence are examined. The studies reviewed illustrate some of the major conceptualizations of the family's influence on intellectual development and achievement. Because of space limitations, not every pertinent line of research is included. Studies of the family's influence on children's social development are not included, although it is acknowledged that social development is probably intimately related to cognitive development and achievement. A review of the various parent programs designed to enhance children's cognitive development is not included. These intervention programs are important applications of existing knowledge and have been covered in previous reviews (e.g., Clarke-Stewart, 1978b; Goodson & Hess, 1978). The validity of various measures of intelligence or achievement used
The Television Industry as a Market of Attention

Abstract In this article, I present an economist’s perspective on the TV industry and view it as a so-called two-sided market, with advertisers on the one side benefiting from the presence of TV viewers and TV viewers on the other side having a dislike for advertising on TV. I use this framework to discuss the likely future development of pay TV, in particular how a future increase in competition in the TV industry will affect the prevalence of pay TV over advertising-financed TV.
The Reliability of Three Devices Used for Measuring Vertical Jump Height

Nuzzo, JL, Anning, JH, and Scharfenberg, JM. The reliability of three devices used for measuring vertical jump height. J Strength Cond Res 25(9): 2580-2590, 2011—The purpose of this investigation was to assess the intrasession and intersession reliability of the Vertec, Just Jump System, and Myotest for measuring countermovement vertical jump (CMJ) height. Forty male and 39 female university students completed 3 maximal-effort CMJs during 2 testing sessions, which were separated by 24-48 hours. The height of the CMJ was measured from all 3 devices simultaneously. Systematic error, relative reliability, absolute reliability, and heteroscedasticity were assessed for each device. Systematic error across the 3 CMJ trials was observed within both sessions for males and females, and this was most frequently observed when the CMJ height was measured by the Vertec. No systematic error was discovered across the 2 testing sessions when the maximum CMJ heights from the 2 sessions were compared. In males, the Myotest demonstrated the best intrasession reliability (intraclass correlation coefficient [ICC] = 0.95; SEM = 1.5 cm; coefficient of variation [CV] = 3.3%) and intersession reliability (ICC = 0.88; SEM = 2.4 cm; CV = 5.3%; limits of agreement = −0.08 ± 4.06 cm). Similarly, in females, the Myotest demonstrated the best intrasession reliability (ICC = 0.91; SEM = 1.4 cm; CV = 4.5%) and intersession reliability (ICC = 0.92; SEM = 1.3 cm; CV = 4.1%; limits of agreement = 0.33 ± 3.53 cm). Additional analysis revealed that heteroscedasticity was present in the CMJ when measured from all 3 devices, indicating that better jumpers demonstrate greater fluctuations in CMJ scores across testing sessions. To attain reliable CMJ height measurements, practitioners are encouraged to familiarize athletes with the CMJ technique and then allow the athletes to complete numerous repetitions until performance plateaus, particularly if the Vertec is being used.
X-Ray Emission from Wind-blown Bubbles. III. ASCA SIS Observations of NGC 6888

We present ASCA SIS observations of the wind-blown bubble NGC 6888. Owing to the higher sensitivity of the SIS for higher energy photons compared to the ROSAT PSPC, we are able to detect a T ~ 8 × 106 K plasma component in addition to the T ~ 1.3 × 106 K component previously detected in PSPC observations. No significant temperature variations are detected within NGC 6888. García-Segura & Mac Low's analytical models of WR bubbles constrained by the observed size, expansion velocity, and mass of the nebular shell underpredict the stellar wind luminosity and cannot reproduce simultaneously the observed X-ray luminosity, spectrum, surface brightness profile, and SIS count rate of NGC 6888's bubble interior. The agreement between observations and expectations from models may be improved if one or more of the following ad hoc assumptions are made: (1) the stellar wind luminosity was weaker in the past, (2) the bubble is at a special evolutionary stage and the nebular shell has recently been decelerated to of its previous expansion velocity, and (3) the heat conduction between the hot interior and the cool nebular shell is suppressed. Chandra and XMM-Newton observations with high spatial resolution and high sensitivity are needed to accurately determine the physical conditions of NGC 6888's interior hot gas for critical comparisons with bubble models.
