Nilsson, Sebastian. "The Current State of DDoS Defense." Thesis, Blekinge Tekniska Högskola, Institutionen för programvaruteknik, 2014. http://urn.kb.se/resolve?urn=urn:nbn:se:bth-3933.
Full textAbstract:
A DDoS attack is an attempt to bring down a machine connected to the Internet. This is done by having multiple computers repeatedly sending requests to tie up a server making it unable to answer legitimate requests. DDoS attacks are currently one of the biggest security threats on the internet according to security experts. We used a qualitative interview with experts in IT security to gather data to our research. We found that most companies are lacking both in knowledge and in their protection against DDoS attacks. The best way to minimize this threat would be to build a system with redundancy, do a risk analysis and revise security policies. Most of the technologies reviewed were found ineffective because of the massive amount of data amplification attacks can generate. Ingress filtering showed promising results in preventing DDoS attacks by blocking packages with spoofed IP addresses thus preventing amplification attacks.

Full textAbstract:
The focus of this thesis is to analyze cryptographic protocol and algorithm usage based on three different data sets where the largest set contains one million websites. Ciphers, algorithms and different versions of cryptographic protocols are described and discussed. Some of the common attacks that make the ciphers or protocols obsolete are also presented and explained. In order to obtain the data sets and analyze them, a web crawler and a prober program were developed. The results from the analysis show that more popular websites have better security compared to the not so popular ones. The results also show that many broken and insecure ciphers and protocols are still very popular today. The thesis discusses the use of old software as a potential reason for why so many websites support weak protocols and ciphers.

Abeles, Adam-Paul Gavriel. "The development of the current state buffer." Thesis, University College London (University of London), 1999. http://discovery.ucl.ac.uk/1382394/.
Full textAbstract:
This thesis examines a component of Short Term Memory that is responsible for automatically tracking important stimuli in our immediate environment. The component has been termed the "Current State Buffer" (Abeles and Morton, submitted; Barreau, 1997; Barreau and Morton, submitted-, Morton, 1997), and it is argued that current conceptions of the Working Memory model (e. g. Baddeley & Hitch, 1993) do not adequately specify its role as a separate functional element of Short Term Memory. A Developmental perspective was adopted for investigating the Current State Buffer experimentally. The data was collected through the implementation of a novel task (the "Tidy Emu Paradigm"), which involved pre-school children watching an Emu glove puppet tidy away toys into receptacles. The paradigm employed dual-task methodology, consistent with many other studies of Working Memory. The empirical work reported falls into three principal stages. The first demonstrates the Current State Buffer's existence as independent to Working Memory. The lack of interference between performance on a Current State Buffer task and a Visuospatial Sketchpad task was taken as evidence for this. Other explanations for the finding are considered, and further experiments replicate the basic finding. The second stage analyses the architecture of a system that comprises a Current State Buffer and Working Memory. In brief, the data are best described by an architecture where information enters an Environmental Input Buffer, and depending on the nature of the stimulus, it passes either into the Current State Buffer, or into an Interpreter Buffer (Working Memory). At retrieval, the contents of these buffers can independently proceed to an Output Buffer. The final stage explores the effects of increasing the load of the Current State Buffer task. This revealed age-related capacity limitations in Current State Buffer function, and that subjects used age-related strategies to deal with the increase in character load, involving interactions between the Current State Buffer and Working Memory.

Full textAbstract:
Vast consumption of natural resources threats the human life. Growing scarcity of
fresh water is posing a great challenge to humanity as well. Thus many governments
take special measures for efficient use of freshwater. There are many products that
use too much fresh water. Toilet is among these products. In search of new solutions
for lack of fresh water, designers design alternative toilets. However, it is necessary
to understand the evolution of toilets and current state to develop better new
technologies and products.
This thesis investigates the evolution of toilet design throughout the history. Factors
affect toilet design, and changes in their improvement throughout the evolution of
toilets are examined. The study also aims to investigate advantages and
disadvantages of squat and flushed toilets and their current state.

Full textAbstract:
Thesis (M.A.)--Boston University<br>Traumatic dental injury (TDI) is a public health problem that affects millions of individuals each year. Contact sports and sports-related activities such as boxing, basketball, and bicycling are the number one cause for TDI’s. The most common TDI’s resulting from sporting accidents are soft tissue laceration, tooth fracture, luxation and avulsion. Some individuals are more at risk than others in sustaining a TDI due to various predisposing factors. Individuals are at greater risk of dental trauma if they have protruding teeth, insufficient lip closure, and/or teeth that have received restorative dental treatment. Adolescents and teenagers are known to be most affected by TDI’s because they are the subset of the population most involved in contact sports and other physical activities. Mouthguards were developed to prevent the occurrence and severity of these dental injuries. There are three different types of mouthguards currently in use. They are the stock, mouth-formed, and custom-made mouthguards. Stock and mouth-formed mouthguards are the least recommended by dental professionals,
yet in combination are worn the most because of their affordability and ease of use. Custom-made mouthguards are the most accepted mouthguards by the dental community because they are the most adapted to the particular individual, and are associated with the lowest number of TDI’s out of the three types of mouthguards.
Users of mouthguards are nearly three times less likely to sustain a TDI while participating in a sport, compared to non-users. Unfortunately, many active individuals do not utilize mouthguards. Non-users of mouthguards associate wearing of mouthguards with undesirable effects, such as breathing difficulties and speech impairment. The side-effects of mouthguards can be so prevalent that they can potentially cause impairment in ones playing ability. In hopes of increasing the number of mouthguard users, researchers and manufactures have continually found new ways to eliminate the negative side-effects of mouthguards, while enhancing their protective function.
Researchers have found mouthguards made from ethylene vinyl acetate (EVA) to have the lowest report of wearer opposition. EVA materials are soft and durable, but more importantly, can be tailored to satisfy the needs of the individual. Also, certain materials and designs can be incorporated into the EVA material to better the mouthguards protective function. For instance, past experiments have shown the placement of compliant materials, such as Sorbothane, in between two sheets of EVA material will significantly enhance the mouthguards protective capability. However, the joining of multiple materials
may result in thicker and less comfortable mouthguards. More recent mouthguard trials have focused on limiting the thickness of mouthguards, while achieving the same level of protection seen in mouthguards made from multiple materials. Researchers have found the insertion of air cells within the EVA material to be useful technique in minimizing the overall thickness of mouthguards, while preserving the mouthguards protective function. In continuing to meet the high demands of athletes and active individuals, researchers and manufactures must develop newer mouthguards by exploring the effectiveness of other materials, as well as finding alternative methods in which mouthguards can be made.

Full textAbstract:
Education leaders and political leaders worldwide are increasingly placing greater emphasis on developing scientific literacy in response to OECD’s PISA testing. This is also the case in Wales where the results of the 2009 and 2012 scientific literacy tests were significantly lower than the rest of the United Kingdom. This thesis considers interpretations of the term scientific literacy in Wales, including confusion over what the term actually means and an exploration of the potential of renaming it ‘scientific competency’ in order to minimise issues regarding current definition. An alternative definition is considered, in addition to an exploration of the current methods of measuring and improving it within the country. A post-positivist approach was adopted in the research. Data were collected through questionnaires, semi-structured interviews and a case study. The analysis of data revealed that Welsh science teachers often had inadequate skills and understanding regarding scientific literacy and this impacted directly upon their ability to measure and improve it within their lessons. This was due to teachers’ perception of a lack of guidance and training. Although there was substantial consensus about the importance of science and scientific literacy to pupils, this was not adequately translated into scientific literacy practices within schools. Large scale educational reform has led to an emphasis on literacy and numeracy skills, but there has been limited focus on science education. In addition, the Welsh education system and its lack of standardised testing may have produced a lack of rigor within science, leading to a decrease in attainment. The study has implications for the professional development of Welsh science teachers and the general teaching of Science within the country and beyond.

Hagedorn, Till. "Atomic contacts characterized by force and current." Thesis, McGill University, 2011. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=96938.
Full textAbstract:
Contacts between atoms present the reduction of an electronic system to the smallest scale accessible at the present. Field ion microscopy (FIM) and simultaneous scanning tunneling microscopy (STM) and atomic force microscopy (AFM) were used to characterize atomic contacts between a tungsten (W(111)) STM-tip and a gold (Au(111)) sample. The STM-tip was imaged with atomic resolution using FIM and reconstructed in a three dimensional ball model. Force and current were measured simultaneously while the tip approached an atomically flat Au(111) sample to form a contact.A detailed description of the tip production and characterization using an etching setup that was developed for this thesis is introduced. These tips are characterized by field ion microscopy (FIM). The adaptation of a well known three dimensional ball model reconstruction to the tungsten bcc(111) crystal is described and utilized to reconstruct FIM micrographs of W(111) STM-tips. Using several of such tips, the long-range forces of the tip-sample system were analyzed using recent theoretical models, concluding that van der Waals and electrostatic force contributions were negligible for tips with a radius smaller than r_tip = 15 nm within the precision of the FIM-STM/AFM system that was employed for the experiments.Force and current data for different structural modifications of the W(111)-Au(111) SPM tunneling junction are presented and discussed. Findings include that the W-Au junction in geometries which were examined in this thesis do not exhibit the conductive properties of a one-atom contact.A comparison of different theoretical approaches that treat the correlation of force and current in a STM type tunneling junction is presented and the results of this thesis support a F^2 ~ I_t proportionality for a three-atom tungsten tip contacting an atomically flat Au(111) sample.<br>Un contact entre atomes est la réduction d'un système électronique à la plus petite échelle actuellement accessible. La microscopie à champ ionique (field ion microscopy, FIM) et la microscopie à effet tunnel (scanning tunneling microscopy, STM) simultanément à la microscopie à forces atomiques (atomic force microscopy, AFM) ont été utilisées pour caractériser le contact atomique entre une pointe de tungstène (W(111)), un palpeur pour le STM, et un échantillon d'or (Au(111)). La pointe a été imagée par FIM avec une résolution atomique et reconstruite par un modèle de balle tridimensionnel. La force et le courant ont été mesurés simultanément pendant que la pointe s'approchait de l'échantillon d'or (111) atomiquement plat pour y former un contact.Une description détaillée de la production et de la caractérisation des pointes par l'utilisation d'un système d'attaque électrolytique, développé pour cette thèse, est présentée. L'adaptation de la reconstruction par modèle de balle tridimensionnel au cristal de tungstène ccc(111) est décrite, puis utilisée pour reconstruire les pointes W(111). En utilisant plusieurs de ces pointes, les forces à longue portée du système pointe-échantillon ont été analysées en utilisant de récents modèles théoriques, ce qui a permit de conclure que les contributions des forces de van der Waals et des forces électrostatiques sont négligeables pour des pointes de rayon inférieur à r_pointe = 15 nm, compte tenu de la précision du système FIM-STM/AFM employé pour les expériences.En lien avec les simulations qui prennent en compte les forces d'interaction pointe-échantillon et les propriétés conductrices de la séparation des contacts, des données de force et de courant pour différentes modifications structurelles de la jonction tunnel W(111)-Au(111) sont présentées et analysées. Entre autres choses, il est montré que la jonction W-Au, pour les géométries étudiées dans cette thèse, ne présente pas les propriétés conductrices d'un contact monoatomique.En comparant différentes approches théoriques qui traitent de la corrélation entre la force et le courant dans une jonction tunnel de type STM, les données pour la jonction W(111)-Au(111) sont mises en relation avec ces lois de puissance. Les résultats de cette thèse indique une proportionnalité F^2 ~ I_t pour une pointe de tungstène à 3 atomes faisant contact avec un échantillon d'or (111) atomiquement plat.

Under de senaste åren har risk kapitalmarknaderna stått inför flera signifikanta problem. Den svenska VC industrin har minskat med över 60 % sedan Dotcom-kraschen. Antalet aktiva VC- företag har minskat i antal från 100-200 till endast 5-10 större VC-företag. Jämför man dagens marknad med hur den såg ut innan Dotcom-kraschen, så fanns det betydligt fler aktiva företag inom den svenska VC-industrin. Nya finansieringsformer har trätt in på marknaden som bland annat Evergreen fonder och crowd-funding. Den svenska VC-industrin har kännetecknats av en "rensning" av marknaden var tionde år, och var femte år uppstår en mindre krasch på marknaden. De svenska riskkapitalaktörerna har tagit en högre risk än vad som faktiskt var motiverat. Syndikatinvesteringar görs för att undvika investerarnas enskilda risk. Detta fenomen kan illustreras genom de två lyckosamma Svenska investeringarna, Spotify och iZettle. Riskkapitalmarknaden har varit karakteriserad av legala hinder vilket skapat flera stora problem. Trots detta finns det positiva trender och förändringar som idag genomförs på marknaden. Dett kommer lyfts fram ytterligare i arbetet. Bland annat har det diskuterats att införa ett skatteavdrag vilket anses vara fördelaktigt för riskkapitalbolagen. Detta arbete fokuserar huvudsakligen på de olika finanseringsformerna och de olika marknadsaktörerna. Fokus ligger på utvecklingen av industrin och dess aktuella trender, men även på den kommande framtiden. Studien är baserad på intervjuer med marknadsaktörer och på befintlig forskning vilket ger en god insikt i den Svenska riskkapitalbranschen.

CHDS State/Local<br>Approved for public release; distribution is unlimited<br>The Arctic environment is in a state of flux and the U.S. government must be prepared to handle the evolution and capitalize on the opportunities. Once barren and desolate, the Arctic is slowly coming to life with industry and commerce brought about by receding ice conditions. Along with that comes the need for a comprehensive and actionable Arctic policy. The other Arctic nations that ring the North Pole are quickly adapting to the shifting Arctic. Unlike the U.S., they have established Arctic policies, are implementing plans to operate in the region, and taking advantage of the opportunities that this new frontier has to offer. The U.S. framework is the National Strategy for the Arctic Region. The plan is short on detail and aspirational in nature. It lacks clear direction and authority. The U.S. has yet to commit to its role as an Arctic nation. The U.S. Arctic lacks infrastructure such as a deep-water port, a joint military base, and additional heavy icebreaker assets. Additionally, there is no lead agency that has authority and funding to carry out U.S. Arctic objectives. Under the current state of affairs, the U.S. is vulnerable to security, economic, and sovereignty issues in the Arctic.

achieve new sport results in their age categories. Participation in competitions,
competitive activities become a target factor and a significant additional motivation
for further training. For some athletes it is a partial return to youth, for others it is
pleasure or the possibility of self-affirmation. But for most veteran sports including
badminton this is a meeting of like-minded people, a purposeful, disciplining
lifestyle, which gives optimism and confidence, encourages creative selfimprovement,
but instead it brings a sense of satisfaction, reliability, spiritual
freedom, a successful solution to many everyday problems. Veteran sport improves
the quality of life, gives free time from professional and domestic activities.

Informationssäkerhet är ett växande problem bland organisationer. Ett stort antal säkerhetsöverträdelser innefattar vårdslöshet bland anställda eftersom den mänskliga uppförande anses vara den viktigaste faktorn för informationssäkerhet. Därför är det avgörande för organisationer att utveckla en informationssäkerhetskultur. Syftet med denna studie är att öka vår förståelse av informationssäkerhetskulturen och belysa människans roll i informationssäkerhet. En kvalitativ systematisk litteraturöversikt från 2015 till 2019 gav 27 journalartiklar som identifierade nyckelkoncept inom forskningsområdet. Resultatet uppvisar fyra olika konceptkategorier; Förstå informationssäkerhetskultur, Informationssäkerhetspolicy lydnad, Kognition och medvetenhet. 26% försökte definiera och konceptualisera och även mäta informationssäkerhetskultur. 44,4% diskuterade Informationssäkerhetskultur som lydighet med ISP, 22,2% påpekar säkerhetsbeteende med hjälp av kognitiva modeller, och slutligen 7,4% kännetecknar kunskap och medvetenhet som motiverande faktor för informationssäkerhetskultur. Dessa resultat tyder på att informationssäkerhetskultur är ett framväxande område och att mänskligt beteende går utöver policy lydighet. Akademiker föreslår att samhällsvetenskapliga tillvägagångssätt ger djupare förståelse för mänskligt organisatoriskt beteende mot säkerhet. Organisationer bör därför kultivera ISC genom att uppmuntra anställda att bete sig informationssäkert snarare än att bete sig enligt policyriktlinjer.<br>Information security is a growing concern among organisations. A large number of security breaches involve employee negligence as human activity is considered as a critical factor in information security. Therefore, organisations must cultivate an information security culture (ISC). The purpose of this study is to enhance our understanding of information security culture and elucidate the human’s role in information security. A qualitative systematic literature review from 2015 to 2019 yielded 27 journal articles which identified key concepts within the research field. Result demonstrate four sets of concept categories; Understanding ISC, Information Security Policy (ISP) compliance, Cognition and Awareness. 26% attempted to conceptualise measure ISC, 44.4% discussed ISC as compliance with ISP, 22.2% points out security behaviour with cognitive models, and finally 7.4% attribute awareness training as motivating factor for ISC. These findings suggest that ISC is a nascent field and that human behaviour goes above and beyond policy compliance. Academics suggest that social science approaches provide a deeper understanding of human organisational behaviour towards security. Organisations should cultivate ISC by encouraging employees to behave securely rather than behave as directed by policies.

Full textAbstract:
Environmental management accounting (EMA) is attracting increased recognition as a management tool that assists in improving financial and environmental performance through enhanced environmental accountability. Various industries have been included in EMA-related research and study, but universities have typically failed to be the focus of the attention. This research studied the experiences of key managers from five universities to explore potential factors influencing the decision to adopt, or not to adopt, EMA within the higher education sector. For the purpose of this study, EMA is defined as the generation, analysis, and use of monetary (or financial) and physical (or non-financial) environment-related information in order to improve organisational financial and environmental performance. The two objectives of this study were to understand current accounting practices for managing major environmental costs, and to identify factors influencing EMA adoption within universities. For the purpose of this study, the major environmental costs referred to are limited to the costs pertaining to the consumption of electricity, water and paper, and the generation of wastes. A case study methodology was followed using semi-structured interviews of key personnel with four different management functions (i.e. environmental management, management accounting, senior management, and heads of academic schools) within each university, and performing content analysis on the transcribed interview data. Specifically for achieving the second research objective, a theoretical framework that considers four theories was embraced to guide the data collection and focus the study. The four theories are contingency theory, institutional theory, legitimacy theory, and stakeholder theory. The findings of the first research objective revealed that there was a general lack of EMA utilisation within the case universities. This was in part due to a perceived lack of appreciation by key personnel of the extent of environmental costs being incurred, but arguably mainly because of the absence of relevant environmental cost information being brought to the attention of senior management. Although environmental sustainability was promoted as important from an environmental management perspective, efforts to improve internal environmental accountability, in particular from an accounting perspective, were still absent. In relation to the second research objective, it was found that five key barriers contributed to this lack of EMA utilisation within the five case universities, and they were attitudinal, financial, informational, institutional, and management barriers. Among the factors that provide further explanations about how each barrier influences EMA adoption, resistance to change, resource constraints, (a lack of) legitimacy considerations, and a lack of environmental responsibility & accountability were found to be strong factors, as they were supported in all of the five cases. Apart from the theoretical extension to this area of research, the results and findings of this study supported the uses and applications of EMA by the higher education sector. Much more can, and should, be done by universities in relation to how they account for the environment. This can provide benefits not only for the sector itself, but also for the environment in which we live.

It is not uncommon to read about hacker attacks in the newspaper today. The hackers are targeting governments and enterprises, and motives vary. It may be political or economic reasons, or just to gain reputation. News about smaller systems is, unsurprisingly, not as common. Does this mean that security is less relevant of smaller systems? This report investigates the threat model of smaller web applications, to answer that very question.Different attacks are described in the detail needed for explaining their threat but the intention is not to teach the reader to write secure code. The report does, however, provide the reader with a rich source of references for that purpose. After describing some of the worst threats, the general cloud threat model is analyzed. This is followed by a practical analysis of a cloud system, and the report is closed with general strategies for countering threats.The severe destruction that a successful attack may cause and the high prevalence of those attacks motivates some security practices to be performed whenever software is produced. Attacks against smaller companies are more common now than ever before

Full textAbstract:
The aim of this study is to make an inventory of the charging infrastructure for electric vehicles in Uppsala municipality. The 89 public charging outlets in the area has been compiled according to their outlet type and power output and located in a map. The charging stations are deployed in the centre of Uppsala and in the outskirts, mainly the eastern parts. The total installed power of the charging outlets in Uppsala is 1036 kW. Potential energy use of the charging outlets has been calculated with several different coverage ratios. The result of potential energy use in a year with 100% coverage ratio is approximately 9 GWh which as an example equals 70% of Ångström Laboratory's electric energy use or 0.6% of Uppsala municipality's over a year. With data from 16 specific charging stations in Uppsala and other cities, coverage estimates have been done with a result between less than 1% up to 13%. It is concluded in this study that further measurements of the charging outlets' electric energy consumption are necessary in order to calculate coverage ratios and coordinate an expansion of the charging infrastructure.

Full textAbstract:
Rising urbanisation, global warming and climate change are posing a threat to the environment. This work is dedicated to green infrastructure as a concept that is helping to mitigate the negative effects on the environment. Focus will be held on Slovakia and its progressiveness in the field of green infrastructure. The aim of this thesis is to find whether there are any obstructions in the process of the development of green infrastructure and also, analyze and evaluate the current and past projects and strategies to reflect how Slovakia has progressed in this field in the past 10 years. As a method, qualitative method of structured interviews has been selected. The interviews were conducted with four experts within the field of green infrastructure in Slovakia. Multiple obstacles have been found that propose negative influences on the implementation of green infrastructure. The major obstacles are the slowly adapting legislation, ownership relations, undersized funding and lack of documentation. The prioritisation of the grey infrastructure instead of green and blue is also present, as well as the insufficient awareness of the general public about the benefits of green infrastructure. Slovakia's progression in the theoretical aspect of green infrastructure could be perceived as positive over the past 10 years. Multiple adapted strategies, either from the European Union or Slovakia's own, represent the improvement as well as the terminology that is more included in the law and policies. From an empirical standpoint, it is not possible to evaluate the progression, due to the complexity of green infrastructure and a lack of documentation. Multiple issues are affecting the state of green infrastructure in Slovakia, however, it seems that Slovakia could be on the right track into the future. By addressing these issues, Slovakia could strive for a more sustainable environment and development in the future.

Full textAbstract:
Today’s global market and growing competition set an increasing strain to manufacturing companies. Shorter product lifecycles automatically lead to shorter production ramp up periods and, therefore, set a higher strain on the manufacturing systems. The concept of reconfigurable manufacturing systems (RMS) was developed in the early 1990s and has now gained more interest than ever. An RMS is designed to quickly respond to changes in market demand, by adapting its functionality as well as its capacity to the current market requirements. In order to achieve this, an RMS is characterised by six core characteristics: modularity, integrability, diagnosability, convertibility, scalability and customisation. By complying with these characteristics, the manufacturing system can meet the required responsiveness to functionality and capacity changes. Academia has been focusing on the development and design of new RMSs, however, there is a lack in research on converting existing manufacturing systems towards reconfigurability. Additionally, few models assessing a manufacturing system’s current state in terms of reconfigurability are available in literature. The existing reconfigurability assessment models were proven to be rather theoretical and difficult to use by practitioners in industry. Therefore, the need for a reconfigurability assessment model applicable in industry arose. This study focuses on the analysis of enablers of a reconfigurability manufacturing systems as well as on assessing the reconfigurability of an existing manufacturing system in an industrial setting. For this purpose, a detailed reconfigurability assessment model has been developed, based on literature studies and a case study at a case company. A focus of the development of the model has been set on usability in industry. The outcome was an assessment model developed in Microsoft Excel that gives an overview on the reconfigurability of each characteristic as well as the manufacturing system’s overall reconfigurability. The model was subsequently tested and verified at the case company. The final reconfigurability assessment model is presented and explained at the end of this study. This study shows, that through the use of theory about RMS and input from industry it was possible to develop a current state assessment model regarding reconfigurability. To make the model generalisable and adaptable to different industrial settings, further testing in different manufacturing fields and research within RMS is required.<br>CARV

Full textAbstract:
<p> This study explored the current state of secondary social studies in Western New York (WNY) through the lens of social studies orientations, specifically the traditional, disciplinary, and progressive strands (Fallace, 2010), and their alignment with the <i>K-12 Social Studies Framework </i>, approved by NYS’s Department of Education in 2014, with new NYS Regents assessments to begin in 2019. It was, therefore, important to collect baseline data on secondary social studies teachers’ social studies purpose, practices, and knowledge of NYS reforms. </p><p> A mixed-method study began in the spring of 2017, which collected data from the <i>WNY S4</i> survey and two focus groups. Survey participants totaled <i>n</i> = 136, representing six counties in WNY; focus group members totaled <i>n</i> = 9. The <i>WNY S4</i> replicated survey items from a nationwide instrument, <i>Survey on the Status of Social Studies–S4</i> (Fitchett & VanFossen, 2013) and analyzed data with descriptive and inferential statistics. The researcher developed a semi-structured interview guide to collect focus group data, which were analyzed by the long-table approach (Krueger & Casey, 2009). </p><p> Major survey findings were: (1) 99% reported an unawareness of their <i> state/district standards</i>; (2) 100% reported developing <i>critical-thinking skills</i>, while 64% reported <i>content knowledge</i> as primary goals; and (3) top-ranked instructional practices were 87% <i> teach political history</i>; 83% <i>teach social history</i>; and 82% <i>examine sources</i>. Analyses of <i>t</i>-tests indicate gender and grade level-band indicators are influential to instructional practices. For example, female and high school teachers seem to engage students more often in non-history content emphases, such as <i>diversity of religious views, economics</i>, and <i>historiography</i> while also de-emphasizing the <i>lecture</i>; hence aligning more with the disciplinary strand and less with the traditional strand. </p><p> Focus group results pinpoint a struggle between participants’ intentions versus actual practice which may impact alignment to NYS social studies reforms. Misalignment attributed to teacher’s purpose being overshadowed by their own instructional choices or outside factors, such as assessments, time, and other school district issues. Five out of nine focus group participants associated with the hybrid disciplinary-progressive approach, suggesting that secondary social studies teachers do not situate themselves to a single social studies orientation; and also consistent with past studies (Long, 2017; Vinson, 1998). </p><p> Overall, <i>WNY S4</i> data suggests when purpose and practices are more closely aligned to the disciplinary and progressive approaches, secondary social studies instruction may find greater success with NYS social studies education reforms. In addition, gender and identified grade level-band (middle school and high school) differences provide insights for developing and tailoring professional development for different groups of teachers. </p><p> Two recommendations for policy and practice include: (1) refine the social studies orientation model into a continuum, and (2) apply the <i>Social Studies Purpose Compass</i> developed by the researcher to guide instructional alignment with NYS social studies reforms.</p><p>

Hewitt, Desmond. "Excellence in critical condition : the current state of English higher education." Thesis, University of Warwick, 2015. http://wrap.warwick.ac.uk/77135/.
Full textAbstract:
This thesis argues that excellence is emancipatory in the sense that it promotes individual and collective transformation and it traces this idealized concept back to Aristotle and the concept of eudaimonia (Aristotle: 2009). This is the idea that excellence promotes happiness and well-being; it enables human beings to flourish and live to their full potential. In short, the thesis is about the potential of higher education to transform lives, in particular those of young people. Thus the fundamental premise of the thesis is that a legitimating principle of English higher education is excellence defined as the Hellenic ideal and that excellence is emancipatory. The thesis operates from the perspective of Critical Theory and operationalizes the theories and concepts of Habermas. It argues that the political discourse of excellence – the economic imperative of competition - eclipses emancipatory excellence in discourse but that in the lifeworld of the university this transformational concept of higher education remains unaffected as a legitimating principle, despite recent government reforms. In a further subsidiary argument, the thesis argues that the emancipatory interests of the university, particularly those of social science are inextricably linked to those of wider society (Barnett: 1994; 2; Habermas: 1977; 1978; 1988) and that this critical normative claim can be realized in an ideal speech situation. The thesis argues that the ideal speech situation already exists in the scientific-public validation of Critical Theory geared at world construction (Strydom: 2011; 158) but that a space for a new discursive event exists in the wider public community of knowledgeable social agents (Bohman: 1999; 475; Nowotny: 1993; 308). This thesis is argued for using material from in-depth, semi-structured, conversation-led research interviews which were conducted with senior administrators, higher education policy specialists and academics across the English higher education sector.

A Thesis submitted to The University of Arizona College of Medicine - Phoenix in partial fulfillment of the requirements for the Degree of Doctor of Medicine.<br>The overall goals of this research project were threefold: to characterize how the Helicopter Ambulance system in Arizona is used for trauma, comparison of Ground and Helicopter Ambulance usage, and recommendations to facilitate effective use of the Helicopter Ambulance system. Data for this project were obtained from the Arizona Department of Health Services Trauma Registry. Analysis included descriptive statistics, crosstabulation, calculation of two-year usage rates, and Z-score (for proportions) comparison between Ground and Helicopter Ambulance for statistical significance (using SPSS18/20).
The American Indian/Alaska Native population was the most frequently transported (two-year rate 1572.3/100,000 population; all transport methods). Gila County and Yuma County had the highest rates of Ground Ambulance transport (Gila 1016.8/100,000, Yuma 1161.7/100,000) whereas Maricopa County was much lower (431/100,000). For Helicopter Ambulance use, the most common counties of transport were Navajo and Gila (414.1/100,000 and 606.4/100,000) whereas Maricopa county was much lower (24.2/100,000).

The significance of this project comes in the area of recommendations for system improvement. Recommendations include ground-based triage areas to determine whether a patient should be transported to a Level I trauma center (or whether a lower level of care is acceptable), as well as how the patient should be transported (Helicopter v. Ground Ambulance).

Full textAbstract:
This is a multi-article dissertation that seeks to address the current state of online teaching evaluation processes in post-secondary institutions. The last two decades have seen a dramatic increase in enrollment in online courses at post-secondary institutions. Unfortunately, evaluating online instructors has been a neglected field of research leaving many post-secondary institutions to develop their own evaluation systems. A deeper analysis of the current practices of online instructor evaluation will help administrators to strengthen their evaluation processes, thereby providing more effective online teaching. The first article is a literature review that explores common practices of post-secondary institutions. By performing an extensive review of the literature, it is clear that very little research has been done to address online instructor evaluation beyond student evaluations. The second article compares different approaches to online instructor evaluation in various post-secondary institutions. By performing interviews with administrators, we found that many institutions are using a variety of types of evaluations and not just student evaluations to evaluate online teaching. The third article is a study that explores how well institutions that utilize a master course model evaluate online teaching competencies. This is done by performing a content analysis of their observational rubrics.

Full textAbstract:
The main task of this study focuses on studying the effect of wave-current interaction on currents, storm surge and inundation as well as effects of depth-induced wave breaking, wind field and current on waves by using numerical models. The results show that it is important to incorporate the wave-current interaction effect into coastal circulation, storm surge and inundation models. At the same time, it should consider effects of depth-induced wave breaking, wind field, currents and sea surface elevation in prediction of waves. Specially, we found that: (1) Depth-induced wave breaking plays an important role in wave field in shallow water areas; (2) To more properly model the hurricane induced wave field, it is important to consider the asymmetric structure of the hurricane wind field, the changes in the hurricane translation time history, and the incorporation background wind field into hurricane wind field; (3) For SWH, it will be decreased when waves propagate in the following current direction. On the other hand, current will increase the SWH when waves propagate countercurrent direction. The change of wave propagation direction after crossing Gulf Stream depends not only on refraction, but also on others (e.g. trap waves effect). (4) It is important to introduce wave-current effects into any storm surge and inundation prediction modeling system. Specially, the consideration of wave-induced wind stress, bottom shear stress, and 3-D radiation stress in storm surge and inundation modeling can significantly improve the correctness of the prediction.

Full textAbstract:
State-plane technique was adopted for analysis of a class of resonant de to de power converters. A
comprehensive method was developed to understand the complex operation of a resonant converter,
identify its operating modes along with their regions of occurrence and determine the de characteristics
of the converter in each mode. The method was shown by application to a series resonant converter
(SRC), a parallel resonant converter (PRC) and the family of quasi resonant converters (QRCs). Several
major conclusions were experimentally verified.
By suitably modifying the method, the effect of parasitic losses on the performance of a SRC was also
studied. The operating regions where significant deviations in de characteristics occurred due to losses
were also identified. In addition, from the mode and de analysis of a PRC, a novel resonant buck converter
with de gain almost insensitive to load variations was proposed.
Generalized mode and de analysis applicable to all QRC topological variations were performed using
state-plane diagrams. Four sets of mode and de analyses were shown to be adequate to characterize
the steady-state operation of nearly a hundred QRC variations. This simplified the understanding and
analysis of these converters. Also, two simple circuit rules were introduced using which several QRC
topological variations were generated and evaluated based on relative component stresses.
The state-plane technique was also used to understand and evaluate different control methods of a SRC.
The occurrence of large, undesirable tank energy surges with analog-signal-to-discrete-time-intervalconverter
(ASDTIC) control was investigated and explained using state-plane trajectories. A new control
method called #optimal trajectory control*, which attempts to achieve the fastest response possible was
proposed. By exploiting the structure of SRC state portrait, the tank energy is always kept within bounds
with this control. Experimental implementation was discussed in detail along with experimental
oscillograms which confirm the predicted fast response.<br>Ph. D.

Full textAbstract:
The aim of this thesis is to gather insights on the underlying social factors behind the current state of controller roles in a multinational enterprise. Additionally, the thesis explores the possibility of managing perceptions and expectations of controller roles, in accordance to corporate business objectives. In order to do this, theoretical concepts of Role Theory, Boundary Spanning and Identity Control were utilized. This paper has a qualitative research design and is based on an embedded single-case study. Due to the exploratory nature of the research, the study is based on the method of „systematic combining‟. The objectives of the company were to establish both local and regional controllers as business partners. Findings indicate that the regional controller could focus on business advisory tasks to a large extent due to a formally appointed role, whereas the local controllers were restricted by their role and expectations to focus more on scorekeeping and managerial duties. The term „business partner‟ was spread throughout the organization. By ascribing this label to controllers, other expectations on the role were induced, which also infers a higher hierarchical positioning. Future research could go more in depth on the process of internalizing values.

Full textAbstract:
Neurosurgeons are constantly evolving their field, developing new processes to approach old problems and implementing them in their day-to-day practices. Unlike most specializations in medicine, neurosurgical innovation is highly unregulated. This thesis explores the inadequacies of the two systems most commonly used to oversee innovative neurosurgery: the Regulatory Ethics Paradigm and self-regulation. When neurosurgical innovations are but one component in complex translational trials, neither system proves effective for protecting patients from risks of surgical adverse events. The results of an extensive systematic review of surgically-related adverse events in clinical trials involving the implantation of electrodes or inoculation of tissues to the deep brain regions are presented. The review demonstrates the relatively high baseline level of risk to patients undergoing neurosurgical interventions. It provides evidence of the need for a new model of standardized regulatory oversight for neurosurgical innovations.<br>Les neurochirurgiens font évoluer leur champ d'activité, en développant de nouveaux procédés et en assurant leur intégration dans leur pratique de tous les jours.

Cette thèse explore les insuffisances de deux systèmes qui chapeautent les innovations neurochirurgicales : le < Regulatory Ethics Paradigm> et l'autoréglementation. Lorsque les innovations neurochirurgicales constituent d'une des components d'essais cliniques complexes aucun de ces systèmes ne s'avère efficace pour protéger les patients des risques qui peuvent découler d'actes neurochirurgicaux. Nous présentons les résultats d'une étude systématique des événements indésirables reliée à la chirurgie dans les essais impliquant l'implantation d'électrodes ou l'inoculation de tissus dans les régions cérébrales profondes. Elle atteste d'un besoin criant pour un modèle nouveau et normalise de système de régulation des innovations dans le champ neurochirurgicales.
