description: With the growing number of technologies that have developed over the past several years and the similarly growing number of cyber attacks, people should ideallybe aware of how to keep their information and systems safe. In general, awareness of security and privacy best practices is important for developing good security habits. Learning about real-world security incidents and data breaches can also alert people to the ways in which their information is vulnerable online, thus playing a significant role in encouraging safe security behavior online. In addition to awareness, it is important for people to take action to improve the security of their systems, particularly in the wake of a security incident or data breach. While prior work has been able to study problems about security awareness and incidents within a broad scope due to the affordances of self-reported methodologies, such studies largely relied onhypothetical or experimental scenarios. In this thesis, we take steps towards (1) filling in the gap of a missing empirical understanding of engagement and action with security and privacy events through measurable behaviors, (2) understanding the effectiveness of social media as a platform for increasing the dissemination of security and privacy advice and for encouraging action, and (3) providing specific guidance for how security and privacy informationmay be shared on social media to encourage engagement and re-distribution. Through measurements of real-world browsing and password data, we first show that online engagement with content related to large-scale security and privacy incidents is rare and that very few factors may encourage people to try to read more about incidents. We then show, by specifically analyzing password data, that people rarely take action after password breaches, much less action that is constructive, even when the breach definitely affected them. In understanding social media’s effectiveness for disseminating security and privacy information, we find that discussions about security and privacy are scarce on Facebook and Twitter and that when these topics are discussed, they are often not discussed constructively. Finally, by analyzing Reddit posts about security and privacy, we identify and shed light on howsecurity and privacy information may be shared on social media such that it garners wider spread and effectiveness.

description: Single molecule localization microscopy (SMLM) has been established as an important super-resolution technique for studying subcellular structures with a resolution down to a lateral scale of 10 nm. Usually samples are illuminated with a Gaussian shaped beam and consequently insufficient irradiance on the periphery of the illuminated region leads to artifacts in the reconstructed image which degrades image quality. We present a newly developed patterned illumination SMLM (piSMLM) to overcome the problem of uneven illumination by computer-generated holography. By utilizing a phase-only spatial light modulator (SLM) in combination with a modified Gerchberg-Saxton algorithm, a user-defined pattern with homogeneous and nearly speckle-free illumination is obtained. Our experimental results show that irradiance 1 to 5 kW/cm2 was achieved by using a laser with an output power of 200 mW in a region of 2000 µm2 to 500 µm2, respectively. Higher irradiance of up to 20 kW/cm2 can be reached by simply reducing the size of the region of interest (ROI). To demonstrate the application of the piSMLM, nuclear structures were imaged based on fluctuation binding-activated localization microscopy (fBALM). The super-resolution fBALM images revealed nuclear structures at a nanometer scale.Single molecule localization microscopy (SMLM) has been established as an important super-resolution technique for studying subcellular structures with a resolution down to a lateral scale of 10 nm.

Year: 1948

description: One of the distinguishing features of the modern elementary school is a library. The changes in educational philosophy which have made the child rather than the lesson the center of interest have brought about new methods of teaching. The lesson now becomes a challenge to the child to seek out information from many sources: books, magazines, newspapers, pamphlets, maps, and visual aids. No longer does the more memorizing of a specific assignment mean successful education.

description: The Second World War, often called the Global War, is largely a war of technocracy. The last few decades have seen many discoveries and inventions which, when used in war, have far reaching implications. To a relatively large extent the United States and the United Nations have left many of these discoveries in the theoretical state, thus allowing a large margin of advantage to the Axis Nations who have rather thoroughly exploited, for military purposes, new discoveries at their command. Since the two groups of nations have come to grips it means that survival demands extensive ramifications of all discoveries which in any way will aid in the prosecution of the war.
How can oral language impact on literacy acquisition? : The study of an oral language intervention program with preparatory students in Tasmania
Creators: name: Rowlands, SM
Publisher: name: University Of Tasmania
Year: 2023

description: The purpose of this study was to collect and evaluate reading and writing data related to an oral language intervention program being trialled in two rural schools in north western Tasmania. Two other schools, within ten kilometres, were used as control examples, to determine the effect of the variables and attributes of the intervention program. Prior to this study, school leaders monitoring kindergarten and preparatory student data noted a trend. Early years' students showed declining literacy scores on state-wide assessments. The Tasmanian Educational Performance Services (EPS) state-wide Reading Recovery data also indicated that fewer preparatory students were reading and writing, at an age-appropriate level, as they began Grade one. A multi-method research approach was conducted with twelve preparatory students from each of two intervention and two non-intervention schools, using standard classroom assessment tools to monitor student outcomes. Questionnaires were used with teachers and caregivers, consisting of demographic, Likert scale and open-ended questions. Semi-structured interviews were used to build on quantitative student data and establish a thorough understanding of other issues impacting on student outcomes. The study period was approximately six months, in the second half of the preparatory year. The aim was to determine if the chosen intervention program, Albany District Oral Language Focus (ADOLF) led to measureable improved student outcomes in oral language, reading and writing. This research indicated that all study students, whether classified as 'average' or 'at risk' made gains in some or all of the oral language, reading or writing assessment tools. There was no notable gain to student outcomes at intervention schools for those students of most concern. Teachers indicated that the focused intervention program on questioning developed a culture of questioning and inquiry throughout the preparatory classroom program. Teacher awareness and skill in using questioning was noted as developing and extending student vocabulary as well as supporting the increased time for focused interactions during classroom activities. This thesis attempts to understand oral language learning opportunities, arising from the ADOLF intervention, with the preparatory students participating in this study and the teaching practices that supported them as early readers and writers. Other factors, beyond the school, were considered for their impact on early literacy learning, in relation to improving student outcomes. Nevertheless, this research resulted in further questions being raised for future data collection, review of appropriateness assessment tools and research to be undertaken.

description: A graphene/silicon junction with rectifying behaviour and remarkable photo-response was fabricated by transferring a graphene monolayer on a pillar-patterned Si substrate. The device forms a 0.11 eV Schottky barrier with 2.6 ideality factor at room temperature and exhibits strongly biasand temperature-dependent reverse current. Below room temperature, the reverse current grows exponentially with the applied voltage because the pillar-enhanced electric field lowers the Schottky barrier. Conversely, at higher temperatures, the charge carrier thermal generation is dominant and the reverse current becomes weakly bias-dependent. A quasi-saturated reverse current is similarly observed at room temperature when the charge carriers are photogenerated under light exposure. The device shows photovoltaic effect with 0.7% power conversion efficiency and achieves 88 A/W photoresponsivity when used as photodetector. © 2019 by the authors.

description: This paper investigates a generalized interlacing property between Bessel functions, particularly $J_ν$ and $J_μ$, where the difference $|ν-μ|$ exceeds $2$. This interlacing phenomenon is marked by a compensatory interaction with the zeros of Lommel polynomials, extending our understanding beyond the traditional $|ν-μ| \le 2$ regime. The paper extends the generalized interlacing property to cylinder functions and derivative of Bessel functions, as an application. It is also discussed that Siegel's extension of Bourget hypothesis to rational numbers of $ν$ cannot be further improved to arbitrary real numbers.

description: One of the most striking characteristics of society today is the marvelous development that is everywhere manifest along industrial lines. In nearly every department of industry the simple processes which formerly prevailed have become differentiated into a great variety of activities, and all have been organized into a definite system. Methods of exploiting the earth in search for raw materials, processes of manufacture, and modes of distribution and exchange have become wonderfully complex. The influence of this change is far-reaching. It permeates every phase of life. It operates in the church as well as in the state, in the home as well as in the school.
Stent Induced Carotid Remodeling: A Balloon Sparing Technique for Carotid Revascularization
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2021

description: Background— Carotid artery stent placement is widely utilized to treat high-risk carotid stenosis patients but isassociated with a greater risk of peri-procedure stroke than carotid endarterectomy in standard-risk populations. Weexplore a technique designed to lower this risk by avoiding the use of angioplasty intra-procedurally and allowingmore gradual carotid remodeling to occur.Methods—We compare two groups of consecutively treated subjects. The first group was treated with the traditionalcombination of stent placement and angioplasty (AG; 18 subjects), while the second group utilized stent insertionalone (NAG; 20 subjects). All subjects were treated at a single institution with retrospective data collection. Proceduraland clinical data were collected for analysis.Results— No differences in clinical outcome were noted between the two groups. There was a trend toward moresignificant immediate residual stenosis in the NAG group than the AG groups (22% versus 5%; p=0.06), but at followup imaging, there was no difference between the groups, with the NAG group showing interval luminal gain of 7.5%accounting for the equalization.Conclusion— Avoidance of angioplasty during carotid stent placement is associated with similar clinical andradiographic outcomes; more immediate luminal gains are observed with angioplasty versus more gradual gains withstent placement alone. Given the physiologic reasons to believe this technique could reduce peri-procedure stroke,further evaluation of this technique in a larger population is warranted.

description: Pólya trees fix partitions and use random probabilities in order to construct random probability measures. With quantile pyramids we instead fix probabilities and use random partitions. For nonparametric Bayesian inference we use a prior which supports piecewise linear quantile functions, based on the need to work with a finite set of partitions, yet we show that the limiting version of the prior exists. We also discuss and investigate an alternative model based on the so-called substitute likelihood. Both approaches factorize in a convenient way leading to relatively straightforward analysis via MCMC, since analytic summaries of posterior distributions are too complicated. We give conditions securing the existence of an absolute continuous quantile process, and discuss consistency and approximate normality for the sequence of posterior distributions. Illustrations are included.

We introduce the fidelity-based entropic parameter that can be used as an indicator of quantum chaos. Moreover, we propose to use the fidelity-like parameter comprising the information about the mean number of photons in the system. We shall concentrate on the long-time behaviour of the parameters discussed, showing that for deep chaos cases the quantum fidelities behave chaotically in the classical sense despite their strictly quantum character.

In particular, necessary and sufficient conditions for a Hopf algebra map to be a monomorphism are given.

Prioritising identity : a grounded theory of employees' evaluation of the work-life interface in multinational corporations
Creators: name: Mathison, K
Publisher: name: University Of Tasmania
Year: 2023

description: Are we working to live or living to work? The interface between work and personal life is often viewed as a source of irreconcilable conflict and the predominant worklife metaphors of 'balance' and 'conflict' reinforce this view. Much research in this area assumes that time and resource allocation is at the heart of managing the worklife interface; faced with the work-life conundrum', many employers respond by implementing time and resource-focused initiatives such as flexible working hours and access to special leave provisions. Increasingly, organisations are devoting significant resources to establishing and promoting effective work-life balance policies. But are these responses based on valid assumptions that accurately reflect employees' perceptions of the work-life interface? Anecdotal evidence suggests that, despite the many and varied work-life strategies being implemented in organisations, increasing numbers of employees are engaging with support services outside the workplace to help them manage the intersection between paid employment and family commitments. Many of those seeking support from organisations such as Relationships Australia are male, blue-collar employees in large organisations who have access to, but apparently find unsuitable, the proffered time and resource oriented work-life initiatives. There appears then to be a 'disconnect' between employers' work-life initiatives and employees' experiences and perceptions of the work-life interface.

In addition to little Higgs heavy gauge bosons, this type of models predicts a set of new T-odd fermions, which may show quite interesting signatures at colliders. We study purely leptonic signatures of T-odd leptons at the Large Hadron Collider (LHC).

description: The method of measuring electrical volume resistivity in different directions was applied to characterize the filler orientation in melt mixed polymer composites containing different carbon fillers. For this purpose, various kinds of fillers with different geometries and aspect ratios were selected, namely carbon black (CB), graphite (G) and expanded graphite (EG), branched multiwalled carbon nanotubes (b-MWCNTs), non-branched multiwalled carbon nanotubes (MWCNTs), and single-walled carbon nanotubes (SWCNTs). As it is well known that the shaping process also plays an important role in the achieved electrical properties, this study compares results for compression molded plates with random filler orientations in the plane as well as extruded films, which have, moreover, conductivity differences between extrusion direction and perpendicular to the plane. Additionally, the polymer matrix type (poly (vinylidene fluoride) (PVDF), acrylonitrile butadiene styrene (ABS), polyamide 6 (PA6)) and filler concentration were varied. For the electrical measurements, a device able to measure the electrical conductivity in two directions was developed and constructed. The filler orientation was analyzed using the ratio σin/th calculated as in-plane conductivity σin-plane (σin) divided by through-plane conductivity σthrough-plane (σth). The ratio σin/th is expected to increase with more pronounced filler orientation in the processing direction. In the extruded films, alignment within the plane was assigned by dividing the in-plane conductivity in the extrusion direction (x) by the in-plane conductivity perpendicular to the extrusion direction (y). The conductivity ratios depend on filler type and concentration and are higher the higher the filler aspect ratio and the closer the filler content is to the percolation concentration.

description: There exists a large class of groups of operators acting on Hilbert spaces, where commutativity of group elements can be expressed in the geometric language of symplectic polar spaces embedded in the projective spaces PG($n, p$), $n$ being odd and $p$ a prime. Here, we present a result about commuting and non-commuting group elements based on the existence of so-called Moebius pairs of $n$-simplices, i. e., pairs of $n$-simplices which are \emph{mutually inscribed and circumscribed} to each other. For group elements representing an $n$-simplex there is no element outside the centre which commutes with all of them. This allows to express the dimension $n$ of the associated polar space in group theoretic terms. Any Moebius pair of $n$-simplices according to our construction corresponds to two disjoint families of group elements (operators) with the following properties: (i) Any two distinct elements of the same family do not commute. (ii) Each element of one family commutes with all but one of the elements from the other family. A three-qubit generalised Pauli group serves as a non-trivial example to illustrate the theory for $p=2$ and $n=5$.

description: Man is a social animal. Without participating in social activities and enjoying the social privileges, man cannot live but physically. He has something in common with the rest of the human race and a particular interest in his own community which imposes on and shares with him the same cultural pattern. The different cultures have a universal cultural pattern common to mankind, but in the same time there are many traits which prohibit the different groups from understanding each other, not because of languages, but because of the existence of the cultural barriers. To cross the barriers of cultural islands and the cultural lags, or to be able to narrow the margin of the differences in cultural determination, for the purpose of achieving acquaintance and understand, the world needs an effective communication system. “The process of communication is the web of signals, expectations, and understanding that makes living together possible….”.

description: We derive the exact solutions for electrically charged black holes both in the absence and presence of a cosmological constant in the gravitational theory with Lorentz violation induced by a background Kalb-Ramond (KR) field. The corresponding thermodynamic properties are investigated. It is found that the standard first law of thermodynamics and the Smarr formula remain valid for the charged KR black holes. Nevertheless, the Lorentz-violating effect influences their ranges of local thermodynamic stability and the first- and second-order phase transition points. Furthermore, to examine the impact of Lorentz violation on the motion of test particles in the spacetime, we analyze the shadow and the innermost stable circular orbit (ISCO) of these black holes. Our results reveal that both the shadow and ISCO radii exhibit a high sensitivity to the Lorentz-violating parameter $\ell$, with a decrease observed as $\ell$ increases.

title: A Model for Designing Surface Drainage Systems In Nearly Level Agricultural Lands
Creators: name: Rojas, Rafael Maria
Publisher: name: Utah State University
Year: 1976

description: The increasing demand for reclamation of periodically waterlogged nearly level agricultural lands in humid tropical areas and the hazard of soil deterioration and soil moisture balance disturbances by current land forming methods suggests the need for investigations of new surface drainage design procedures. This report presents a rainfall-runoff model for simulating hydrographs from ungaged agricultural plots. The model is based on routing procedures and utilizes common soil and hydrologic data. Tests made with several small agricultural water-sheds indicate that the model could be a useful tool in simulating surface drainage design.
Input data for the model consists of (a) rainfall data, (b) infiltration, (c) watershed characteristics, and (d) soil parameters. The model could be used with any computer or desk calculator. Since the model was developed for surface drainage purposes, its use is limited to wet conditions in homogeneous and rectangular plots.
The justification for teaching colour
Creators: name: Shelly, Barbara Gail
Publisher: name: University of British Columbia
Year: 2011

description: This thesis attempts to justify an intensive course in colour for Fine Arts students at the university and art school. The teaching of colour is justified from a theoretical and a practical standpoint. In the first section, the various disciplines concerned with the subject of colour are examined for evidence of colour's effect on the life of the human organism. This evidence is compiled from reports of research in educational and psychological journals, from the theories en* discussions available in books on the physical and psychophysical evaluation of colour and the physiology and psychology of colour vision. The hypothesis that colour influences man's life pattern is substantiated in this compilation. The phenomenon of colour is not only a significant aspect of man's environment, it is also an element of art. The responsibility for its teaching lies with the art educator. The second hypothesis that the presentation of colour to university and art school students is incompatible with practical needs is supported by an evaluation of contemporary pedagogy of colour in Vancouver. Interviews with teachers of Fine Arts in the Faculties of Arts and Education, The University of British Columbia, in the Vancouver School of Art and the Vancouver Art Gallery revealed that for the most part, the method of teaching colour perpetuates the instructor's own background in colour wheel theory and. the mixture of pigments. Interviews with student colourists, and questionnaires distributed among Fine Arts majors in the Faculty of Education revealed that the theoretical presentation of colour has little application to the practical needs of art students. This thesis concludes with a proposed revision in the approach to colour with students of Fine Arts. The outlined course is designed to develop the ability to manipulate colour through problem-solving experiences.

description: Human manipulation skills are filled with creative use of physical contacts to move the object about the hand and in the environment. However, it is difficult for robot manipulators to enjoy this dexterity since contacts may cause the manipulation task to fail by introducing huge forces or unexpected change of constraints, especially when modeling uncertainties and disturbances are present. A properly designed robot compliance can provide the robot with the resilience and reliability in handling contacts.This thesis proposes a framework for robust manipulation with contacts using active compliance. We provide quasi-static modeling that shows the necessity of compliance in rigid body manipulation. We further identify two causes of failure in manipulation: kinematic ill-conditioning and unexpected change of contact modes, and illustrate how the robot compliance can help avoid those failure types in manipulation tasks. First, we propose robustness metrics for each type of the failures. The metrics measure the amount of modeling uncertainty and the magnitude of external disturbance forces the system can take before a failure happens. Second, we provide methods to optimize the robustness metrics in a compliance control setting, as well as methods to improve the robustness of a contact-implicitmotion planning. Finally, we experimentally validate our proposed approaches in a variety of manipulationproblems. Our method efficiently finds solutions with consistent high quality during testing. The result shows that our framework trades-off well between model complexity and accuracy, captures major factors in manipulation problemswhile keeping a low computation burden.

description: Background: All soft and solid surface structures in the oral cavity are covered by the acquired pellicle followed by bacterial colonization. This applies for natural structures as well as for restorative or prosthetic materials; the adherent bacterial biofilm is associated among others with the development of caries, periodontal diseases, peri-implantitis, or denture-associated stomatitis. Accordingly, there is a considerable demand for novel materials and coatings that limit and modulate bacterial attachment and/or propagation of microorganisms. Objectives and findings: The present paper depicts the current knowledge on the impact of different physicochemical surface characteristics on bioadsorption in the oral cavity. Furthermore, it was carved out which strategies were developed in dental research and general surface science to inhibit bacterial colonization and to delay biofilm formation by low-fouling or “easy-to-clean” surfaces. These include the modulation of physicochemical properties such as periodic topographies, roughness, surface free energy, or hardness. In recent years, a large emphasis was laid on micro- and nanostructured surfaces and on liquid repellent superhydrophic as well as superhydrophilic interfaces. Materials incorporating mobile or bound nanoparticles promoting bacteriostatic or bacteriotoxic properties were also used. Recently, chemically textured interfaces gained increasing interest and could represent promising solutions for innovative antibioadhesion interfaces. Due to the unique conditions in the oral cavity, mainly in vivo or in situ studies were considered in the review. Conclusion: Despite many promising approaches for modulation of biofilm formation in the oral cavity, the ubiquitous phenomenon of bioadsorption and adhesion pellicle formation in the challenging oral milieu masks surface properties and therewith hampers low-fouling strategies. Clinical relevance: Improved dental materials and surface coatings with easy-to-clean properties have the potential to improve oral health, but extensive and systematic research is required in this field to develop biocompatible and effective substances. © 2020, The Author(s).
Naturalness and stability of the generalized Chaplygin gas in the seesaw cosmon scenario

description: The seesaw mechanism is conceived on the basis that a mass scale, $ξ$, and a dimensionless scale, $s$, can be fine-tuned in order to control the dynamics of active and sterile neutrinos through cosmon-type equations of motion: the seesaw cosmon equations. This allows for sterile neutrinos to be a dark matter candidate. In this scenario, the dynamical masses and energy densities of active and sterile neutrinos can be consistently embedded into the generalized Chaplygin gas (GCG), the unified dark sector model. In addition, dark matter adiabatically coupled to dark energy allows for a natural decoupling of the (active) mass varying neutrino (MaVaN) component from the dark sector. Thus MaVaN's turn into a secondary effect. Through the scale parameters, $ξ$ and $s$, the proposed scenario allows for a convergence among three distinct frameworks: the cosmon scenario, the seesaw mechanism for mass generation and the GCG model. It is found that the equation of state of the perturbations is the very one of the GCG background cosmology so that all the results from this approach are maintained, being smoothly modified by active neutrinos. Constrained by the seesaw relations, it is shown that the mass varying mechanism is responsible for the stability against linear perturbations and is indirectly related to the late time cosmological acceleration.

description: We present neutron scattering results on the magnetic excitations in the spinel compounds Li$_x$[Mn$_{1.96}$Li$_{0.04}$]O$_4$ (x= 0.2, 0.6, 0.8, 1.0). We show that the dominant excitations below T ~ 70 K are determined by clusters of Mn^4+ ions, and that these excitations mimic the E/T-scaling found in quantum critical systems that also harbor magnetic clusters, such as CeRu$_{0.5}$Fe$_{1.5}$Ge$_2$. We argue that our results for this classical spinel compound show that the unusual response at low temperatures as observed in quantum critical systems is (at least) partially the result of the fragmentation of the magnetic lattice into smaller units. This fragmentation in quantum critical systems is the direct and unavoidable result of intrinsic disorder.

description: SGR J1550-5418 (previously known as AXP 1E 1547.0-5408 or PSR J1550-5418) went into three active bursting episodes in 2008 October and in 2009 January and March, emitting hundreds of typical Soft Gamma Repeater (SGR) bursts in soft gamma-rays. The second episode was especially intense, and our untriggered burst search on Fermi/GBM data (8-1000 keV) revealed ~450 bursts emitted over 24 hours during the peak of this activity. Using the GBM data, we identified a ~150-s-long enhanced persistent emission during 2009 January 22 that exhibited intriguing timing and spectral properties: (i) clear pulsations up to ~110 keV at the spin period of the neutron star (P ~ 2.07 s, the fastest of all magnetars), (ii) an additional (to a power-law) blackbody component required for the enhanced emission spectra with kT ~ 17 keV, (iii) pulsed fraction that is strongly energy dependent and highest in the 50-74 keV energy band. A total isotropic-equivalent energy emitted during this enhanced emission is estimated to be 2.9 x 10^{40} (D/5 kpc)^2 erg. The estimated area of the blackbody emitting region of ~0.046(D/5 kpc)^2 km^2 (roughly a few x 10^{-5} of the neutron star area) is the smallest "hot spot" ever measured for a magnetar and most likely corresponds to the size of magnetically-confined plasma near the neutron star surface.

description: The Directory was created to assist transportation data users, policy makers, planners, researchers, information specialists and others in locating statistical contacts and transportation profiles in different countries. It lists, by continent, 1,925 contact points in 189 countries, plus 42 dependencies and areas of special sovereignties. Data entries were restricted primarily to government and quasi-government agencies and organizations. In addition to these, there are 59 transnational organizations that span the interests and responsibilities of several countries, and in some cases even continents. These organizations are listed separately. The Directory begins with a list of available embassy contacts accessible by electronic mail and Internet Site Addresses. Following that is presented a special section on transnational organizations. Next, the continents of North America, Central America, South America, Europe, Asia, Africa, and Oceania are displayed as major sections of the Directory, with listings by individual country.
