Exploring The Use Of Plc Debugging Tools For Digital Forensic Investigations On Scada Systems, Tina Wu, Jason R.C. Nurse

Journal of Digital Forensics, Security and Law

The Stuxnet malware attack has provided strong evidence for the development of a forensic capability to aid in thorough post-incident investigations. Current live forensic tools are typically used to acquire and examine memory from computers running either Windows or Unix. This makes them incompatible with embedded devices found on SCADA systems that have their own bespoke operating system. Currently, only a limited number of forensics tools have been developed for SCADA systems, with no development of tools to acquire the program code from PLCs. In this paper, we explore this problem with two main hypotheses in mind. Our first hypothesis …

Two Challenges Of Stealthy Hypervisors Detection: Time Cheating And Data Fluctuations, Igor Korkin

Journal of Digital Forensics, Security and Law

Hardware virtualization technologies play a significant role in cyber security. On the one hand these technologies enhance security levels, by designing a trusted operating system. On the other hand these technologies can be taken up into modern malware which is rather hard to detect. None of the existing methods is able to efficiently detect a hypervisor in the face of countermeasures such as time cheating, temporary self uninstalling, memory hiding etc. New hypervisor detection methods which will be described in this paper can detect a hypervisor under these countermeasures and even count several nested ones. These novel approaches rely on …

Rules Of Professional Responsibility In Digital Forensics: A Comparative Analysis, Filipo Sharevski

Journal of Digital Forensics, Security and Law

The consolidation of the rules of professional responsibility as recommended by the Committee on Identifying the Needs of Forensic Sciences Community (2009) accents the establishment of an uniform code of ethics emphasizing the importance of enforceability in strengthening the role the forensic science plays within the criminal justice system. Equally pertinent for the domain of digital forensics, this imperative entails a research commitment in comparing and contrasting the respective codes of ethics to illustrate their “variety, specificity and enforceability” in order to inform the discussion on the regulative aspects of the digital forensic discipline. Accordingly, this paper reviews the professional …

The "Bring Your Own Device" Conundrum For Organizations And Investigators: An Examination Of The Policy And Legal Concerns In Light Of Investigatory Challenges, Carla J. Utter, Alan Rea

Journal of Digital Forensics, Security and Law

In recent years, with the expansion of technology and the desire to downsize costs within the corporate culture, the technology trend has steered towards the integration of personally owned mobile devices (i.e. smartphones) within the corporate and enterprise environment. The movement, known as “Bring Your Own Device” (hereinafter referred to as “BYOD”), seeks to minimize or eliminate the need for two separate and distinct mobile devices for one employee. While taken at face value this trend seems favorable, the corporate policy and legal implications of the implementation of BYOD are further complicated by significant investigatory issues that far outweigh the …

Being Trans: An Interpretative Phenomenological Study Of Young Adults, Gemma Lee Taylor

Theses : Honours

Social structures assume a binary classification of gender whereby people are expected to accept the female or male gender expectations and gender roles commonly associated with their biological sex. However, gender identity and gender expression are personal experiences which do not necessarily align with the sex assigned to a person at birth. Young adults who identify as trans resist the predictable relationships and boundaries of sex and gender by embracing diverse gender identities and expressions. Research acknowledging more favourable life experiences of trans youth is limited, despite the importance of a sound knowledge base necessary to provide a positive and …

Eye Movement Patterns As An Indicator Of Task Automaticity, Olga Clarke

Theses : Honours

Automaticity is a vital aspect of daily living, as it allows for tasks to be completed quickly and with the fraction of the cognitive load required for tasks that cannot be completed automatically. Task automaticity is commonly measured with reaction time, which is considered to be an indirect measure of behaviour. As more direct measures are becoming available, there is an opportunity to assess task automaticity in greater detail. The purpose of the current study was to determine whether eye movements change as participants reach task automaticity. The study involved 16 participants who were asked to complete the dot counting …

The Missing Link: Filling The Gap And Achieving Success In Australian Contrabass Auditions, Giovanni Vinci

Theses : Honours

In Australia, a contrabass player who wishes to win a full-time orchestral position must pass a formal audition. Australian contrabass auditions normally consist of both solo works and a set of orchestral excerpts. In order to be successful in the audition, the aspiring musician must meet the standard expected by the adjudicating panel of musicians. This dissertation explores the keys to success in such auditions, shining light upon why some musicians are successful and others not. A series of interviews have been conducted with string musicians around Australia to assist in discovering optimal strategies and approaches to achieving success. Practising …

From Artefact Design To Service Design Thinking Innovations, Erica Ormsby

Theses : Honours

This research will explore the effect of the introduction of service design methods to graphic designers, and whether graphic designers are limited to the design of ephemeral artifacts or instead can play a significant role in the innovation of products and services among larger industry and community based projects in Perth, Western Australia, and perhaps even enrich service design processes themselves. This thesis will examine established graphic design disciplinary processes as well as alterations to those practices via the introduction of service design methods. In addition, these service design processes will also be applied to a complex live service orientated …

Indirect Approaches: A Systematic Review Of Paediatric Dysphagia Interventions, Bianca Piano

Theses : Honours

Background and purpose: Dysphagia can be described as difficulty within the oral, pharyngeal and/or oesophageal phases of deglutition and occurs in approximately 80% of children with developmental disabilities, according to the American Speech and Hearing Association (2015). It occurs when there is impairment to the motor and/or sensory aspects of swallowing, due to a range of disorders affecting the voluntary and reflexive components of deglutition. The ability to swallow safely is essential in preventing medical complications, sustaining life and maintaining social participation. Paediatric interventions can be categorized into three broad approaches; direct, indirect and mixed. At present, two systematic reviews …

Thinking Differently About Reflective Practice In Australian Social Work Education: A Rhapsody, Lynelle Watts

Theses: Doctorates and Masters

There are many different ways of thinking about reflective practice in social work education in Australia. This research utilises a musical metaphor to illustrate this diversity. Written as a piece of music with album notes, the study utilises a reflexive methodology with a qualitative mixed method approach. Three studies were conducted to explore how reflective practice is understood in social work education and practice in Australia. The first study examined my own learning and teaching of reflective practice through an autoethnographic process. The findings indicated a range of models of reflective practice potentially available to the educator. Also explored in …

Disambiguating Company Names In Microblog Text Using Clustering For Online Reputation Management, Fernando Perez-Tellez, John Cardiff, Paolo Rosso, David Pinto

Articles

Twitter is used by millions of users to publish brief messages (tweets) with the purpose of sharing experiences and/or opinions about a product or service. There is a clear need for systems that can mine these messages in order to derive information about the collective thinking of twitterers (e.g. for opinion or sentiment analysis). Tweet analysis is a very important task because comments, opinions, suggestions, complaints etc. can be used for marketing strategies or for determining information on a company’s reputation. For this purpose, it is necessary to automatically establish whether a tweet refers to a company or not, when …

Critical Race Theory: A Strategy For Framing Discussions Around Social Justice And Democratic Education, Wesley Crichlow

Stream 2: Curriculum

The increasing diversity of our classrooms means we must learn to work with, and across, cultural, racial and gendered differences, without falling into diversity management. This paper employs Critical Race Theory (CRT) and paradigmatic frameworks to address social crises in our classrooms—thus demonstrating how we can value (i.e., not erase) our differences and equitably share power in the classroom. Employing an CRT intersectional analysis, I will explore the social, economic, and cultural dimensions of racial (in) justice in diverse contexts (within frameworks that recognize the salience of social identities including, but not limited to, class, and race, ethnicity, gender, sexuality, …

Mandatory Disclosure: A Case Study In How Anti-Corruption Measures Can Affect Competition In Defense Markets, Christopher R. Yukins

GW Law Faculty Publications & Other Works

In the U.S. defense procurement market, regulators require contractors to make “mandatory disclosures” if principals at those firms determine, after due review, that there is credible evidence that the firms engaged in certain crimes (fraud, bribery or gratuities), civil fraud, or significant overpayment by the government. Failure to make such a mandatory disclosure, required by clause and by regulation, can lead to (among other things) the debarment of the contractor -- a potentially devastating result. Mandatory disclosure is a natural extension of a separate requirement, that contractors maintain effective corporate compliance and ethics systems, and the Defense Department’s largest prime …

The Us Legal System On Data Protection In The Field Of Law Enforcement. Safeguards, Rights And Remedies For Eu Citizens, Francesca Bignami

GW Law Faculty Publications & Other Works

At the request of the LIBE Committee of the European Parliament, this study surveys the U.S. system of data protection in the field of federal law enforcement. Since the legal category of “data protection” does not formally exist in U.S. law, the study begins by setting out the substantive and procedural requirements of EU law that are canvassed in the context of information-gathering and surveillance by U.S. law enforcement agencies. The study then analyzes the data protection law governing federal agencies according to two criteria: sources and methods of surveillance and data collection. It first reviews the two principal sources …

Consume Or Invest: What Do/Should Agency Leaders Maximize?, William E. Kovacic, David A. Hyman

GW Law Faculty Publications & Other Works

In the regulatory state, agency leaders face a fundamental choice: should they “consume” or should they “invest?” “Consume” means launching high profile cases and rule-making. “Invest” means developing and nurturing the necessary infrastructure for the agency to handle whatever the future may bring. The former brings headlines, while the latter will be completely ignored. Unsurprisingly, consumption is routinely prioritized, and investment is deferred, downgraded, or overlooked entirely. This essay outlines the incentives for agency leadership to behave in this way and explores the resulting agency costs (pun intended). The U.S. Federal Trade Commission’s health care portfolio provides a useful case …

The Regulation Of Human Iron Metabolism In Hypoxia, Andrew Govus

Theses: Doctorates and Masters

Athletes commonly use altitude exposure in an attempt to improve their aerobic performance at sea level. Altitude exposure enhances erythropoiesis and iron-dependent oxidative and glycolytic enzyme production, for this reason, athletes must maintain a healthy iron balance at altitude. A negative iron balance at altitude may limit such physiological adaptations, potentially reducing the performance benefits of altitude exposure.

This thesis examined the regulation of iron metabolism during acute (~31 min, Study One) and prolonged altitude exposure (14 days, Study Two). Finally, Study Three examined how daily oral iron supplementation influenced haemoglobin mass (Hbmass) and iron parameter responses to prolonged, moderate …

Wellbeing Of Singapore’S Youths, Kong Weng Ho

Research Collection School Of Economics

Given Singapore’s focus on human capital investment in its residents, the nation’s youths have experienced increases in their financial, educational, and physical wellbeing. However, how have our youths fared in their emotional and mental wellbeing? Figures from the World Values Survey show reported a gradual decline in life satisfaction for both general population and youths. Data from four waves of the National Youth Survey confirms this trend. This chapter explores and examines the non-economic channels that may have countered the positive influence of economic success on the wellbeing of youths, namely, changing family structure, heightened stressors, shifting life goals, time …

Results: Confidence scores for inferred climate impacts varied widely from 1 to 16 (very low to …

Indonesian Teachers’ Implementation Of New Curriculum Initiatives In Relation To Teaching Writing In Lower Primary School, Sulfasyah, Yvonne Haig, Caroline Barratt-Pugh

Research outputs 2014 to 2021

This paper reports an investigation of teachers’ implementation of a new Indonesian curriculum, the Kurikulum Tingkat Satuan Pendidikan (KTSP), meaning school-based curriculum. The specific context chosen was the teaching of writing in Year 2 in the primary schools of Makassar City, Indonesia. The teachers’ implementation was examined through the lens of the KTSP’s key constructivist-based concepts. Using qualitative methods, the study found that the teachers’ implementation of the new writing curriculum reflected a traditional view of teaching, despite the intent of the KTSP to move away from this approach to one that better reflected a constructivist approach. The study also …

The Expression Pattern Of Death Associated Protein Kinase1 In Normal Dorsal Root Ganglion Neurons And Following Peripheral Nerve Injury, Maryam Sulaiman Mohammed Al Saadi

Theses

Death-associated protein kinase 1 (DAPK1) is a calcium/calmodulin (Ca^2+/CaM) regulated serine/threonine kinase. An increasing body of evidence supports the significance of DAPK 1 protein in cancer and CNS diseases. The role of DAPK in peripheral nerve regeneration and neuropathic pain remains completely unexplored. The aim of this study is to investigate the expression pattern of DAPK1 along with key pro-and anti-apoptotic cell signaling molecules (p53, Bax, Akt, ERK5, p38) and to verify the possibilities of DAPKI1-NMDA NR2B relationship in dorsal root ganglion neurons (DRG) after 2 hours, 7 days and 14 days following a sciatic nerve injury. Gene …

Social And Acoustic Behavior Of The Leaf-Roosting Bat Thyroptera Tricolor, Bianca Karina Montero

Biological Sciences

The limited availability of refuges may represent an important factor promoting the evolution of sociality, particularly in bats. Spix’s disc-winged bats (Thyroptera tricolor) show highly specialized morphological adaptations that enable individuals to roost inside furled musoid leaves. This roosting ecology presents major challenges, as leaves rapidly unfurl, forcing bats to locate new roosts on a daily basis. Despite the reliance of T. tricolor on such ephemeral roosting resources, bats form stable group associations. The purpose of this study was to characterize the behavioral patterns associated with assessing roosts and any accompanying communication strategies of Spix’s disc winged bats. In the …

Communicating To Change Communication: Alcoholics' Romantic Partners' Mutual-Aid Group Attendance In Relation To Communication With Their Alcoholic Partners, Venla Kuuluvainen, Pekka Isotalus

Iowa Journal of Communication

Although the strain that a romantic partner's alcoholism puts on a relationship is well documented, less is known about the ways in which individuals deal with a malfunctioning relationship of this kind. This qualitative study explores one way of coping with a partner's alcoholism: attending Al-Anon, a world-wide network of mutual-aid groups for alcoholics' friends and families. This paper will look at Al-Anon members' perceptions of their communication experiences at Al-Anon in relation to their communication with their alcoholic partners. The research material is composed of interviews with Finnish Al-Anon members (n=19), as well as their writings (n=128), which have …

Communication And Female Date Initiation: Differences In Perceptions Based On Asesertiveness Of Initiator, Lindsey K. Odom, Erin Sahlstein Parcell, Benjamin M. A. Baker, Valerie Cronin-Fisher

Iowa Journal of Communication

First dates represent an important event in the early development of dating relationships. Commonly, date initiation is a behavior in which men take control in heterosexual relationships; however, more women are conducting this task. Women initiating dates, as opposed to men, has traditionally been viewed as a deviation from American cultural norms for expected behavior. The deviation in behavior could have negative repercussions for women, which was investigated for the current study. College-aged participants (n = 232) completed an online survey regarding their perceptions of two hypothetical women who initiated dates (i.e., one where her assertiveness was high and one …
