Effective Slip Lengths for Stokes Flow over Rough, Mixed-Slip Surfaces
Authors:   , Lund Nathaniel Joseph
Published: November 2021

In this thesis, homogenization and perturbation methods are used to derive analytic expressions for effective slip lengths for Stokes flow over rough, mixed-slip surfaces, where the roughness is periodic, and the variation in slip length has the same period. If the classical no-slip boundary condition of fluid mechanics is relaxed, the slip velocity of the fluid at the surface is non-zero. For simple shear flow, the slip velocity is proportional to the shear rate. The constant of proportionality has dimensions of length and is known as the slip length. Any variation in the slip length over the surface will cause a perturbation to the flow adjacent to the surface. Due to the diffusion of momentum, at sufficient height above the surface, the flow perturbations have diminished, and flow is smooth and uniform. The velocity and shear rate at this height imply an effective slip length of the surface. The purpose of this thesis is to predict that effective slip length.  Homogenization is a technique for finding approximate solutions to partial differential equations. The essence of homogenization is to construct a mathematical model of a physical problem featuring some periodic heterogeneity, then generate a sequence of models such that the period in question reduces with each increment in the sequence. If the sequence is appropriately defined, it has a limit model in the limit of vanishing period, for which a solution can be found. The solution to the limit system is an approximation to the solutions of systems with a finite period.  We use homogenization to find the effective slip length of a system of Stokes flow over a periodically rough surface, described by periodic function h(x; y), with a local slip length b(x; y) varying with the same period. For systems where the period L is smaller than both the domain height P and typical slip lengths, the effective slip length bₑff is well-approximated by the harmonic mean of local slip lengths, weighted by area of contact between liquid and surface: [See 'Thesis' document below for equation.]  We further use a perturbation technique to verify the above expression in the special case of a flat surface, and to derive another effective slip length expression: For a flat surface with local slip lengths much smaller than the period and domain height, the effective slip length bₑff is well-approximated by the area-weighted average of local slip lengths: [See 'Thesis' document below for equation.]
Rising Sulphur and Raising Sheep: Landscape, Identity and Amateur Film in New Zealand c.1923-1939
Authors:   , Hickman Rosina
Published: November 2021

Looking at early examples of amateur filmmaking from the period 1923-1939, which have been deposited in New Zealand's national film archive, Ngā Taonga Sound and Vision, this thesis considers how amateur practice both relates to and deviates from other contemporary forms of visual culture such as professional cinema. Internationally, scholars and archivists have recently begun to examine ways that amateur films or home movies, which document personal, local and everyday experience, supplement other sources of visual history. There have, however, been few studies to date of this aspect of New Zealand's film history. While the idiosyncratic language of films intended for private use complicates their interpretation in an archive, it is argued that home movies display a 'referential coherence' in relation to other media, which offers a way of understanding amateur films as historical documents in the public domain. This relationship is explored looking at holiday films recorded at a popular sightseeing destination and films depicting working life on sheep farms. Portrayed as an exotic wonderland with spectacular geothermal activity and authentic Māori culture on display, Rotorua, as seen in promotional media, exemplified the widespread representation of New Zealand as a scenic playground. Amateur films offer a more ambivalent view of the tourist locality's geography and inhabitants. Made by outsiders familiar with popular representations, amateur tourist films resemble the imagery of professional media in many respects, however, they do so largely without articulating the simplistic narratives of publicity material. Picturesque images depicting rural New Zealand as an idyllic pastoral paradise have a long history across a wide range of media. While idealised scenic views of the countryside, which consistently ignored the social realities of rural existence, appear to presuppose the unfamiliar gaze of an (urban) outsider, rural residents recorded their own impressions of their surroundings on film. Less concerned with scenery than with the scene of daily life, amateur farming films document specific concrete experiences in a particular time and place, yet simultaneously appear to share, if not so much the iconography or aesthetics of professional media, at least some of the wider aspirations of cultural discourses in circulation. It may be concluded therefore that the study of amateur media production contributes to an understanding of how individuals and groups internalise and reproduce, or alternatively disregard, prevailing social ideologies.
A qualitative study investigating the association between social exclusion, stigma and long term problem drug use in a New Zealand town
Authors:   , Wilson Murray David
Published: November 2021

Background: The aim of this study is to investigate the association between problematic drug use (PDU) and social exclusion and stigma in a deindustrialised New Zealand town (DNZT). The purpose of this research is to capture the perceptions; experiences and life course journey of individuals with long term problematic drug use (IPDUs) and contribute new knowledge and understanding of this lived experience.  Method: A review of national and international literature related to the phenomena of social exclusion, stigmatisation and problematic drug use was conducted to theoretically inform the study. The small-scale study employed a qualitative approach that involved a non-probability sample that met the criteria for long-term problematic drug use. This allowed respondents to share their perceptions and experiences of social exclusion, stigma and PDU in their own words and by their own frames of reference. The researcher occupied a position of insider. Following transcription of the interviews a six stage thematic analysis was conducted on the data.  Findings: The downward social and psychological trajectory of this respondent group began before the respondents encountered long-term unemployment and before the onset of problematic drug use, initiated at an early age by common experiences of trauma, exclusion and damaged home environments. For this cohort it appears problematic drug use may have become a coping mechanism or relief from the reverberating impact of stigma, exclusion and marginalisation.  Conclusion: The cohort interviewed show significant experiences of stigma, trauma and a disrupted life journey. These experiences became considerably exacerbated by problematic drug use and it appears most of the respondents have internalised and embraced a permanent status as ‘addicts’ with limited expectation of change. Respondents spoke of being ‘parked’ on methadone in respect of their drug problem and excluded from employment. This research suggests there is a need to look beyond the presented problem of addiction and its apparent solution of methadone maintenance treatment (MMT) and explore a more holistic strength-based approach that addresses issues of inequality, social care and discrimination.
Ennui and Alys: Conceptions of Complex Boredom in Plutarch
Authors:   , Howell Samuel
Published: November 2021

This thesis addresses the conceptualisation of boredom in Plutarch through a survey of relevant lexical terms, and analysis of the depiction of character in the 'Moralia' and the 'Lives..'. A distinction is made between the temporary tedium of simple boredom, and the persistent and spiritual dissatisfaction of complex boredom.  The first chapter is composed of a discussion of the context necessary to understand boredom in an ancient context. It discusses relevant psychological theories for understanding emotion, as well as simple and complex forms of boredom. It also establishes the context for discussing ancient emotions. Depictions of simple and complex boredom in the ancient world prior to the work of Plutarch are summarised and addressed. Similar themes in the works of Seneca, Horace, and Lucretius are also discussed.  The second chapter charts the lexical course of words identified by modern scholarship as relating to concepts of boredom. Their occurrence and significance within Plutarch’s oeuvre are discussed. These terms include ἄλυς (boredom), ἀλύω (wandering, to be distraught), ἀκηδία (lassitude), ἄση (surfeit, distress), ἀπληστία (insatiate greed), κόρος (satiety) and πλησμονή (abundance, surfeit). This analysis attempts to identify the underlying semantic field of these terms, and to assess how much these correspond with modern conceptions of boredom. The discussion focusses on the themes of luxury and leisure, revelry, warfare, philosophy, exile, retirement, and dissatisfaction.  The third chapter attempts to contextualise the lexical research through the use of case studies in Plutarch’s works. The paired 'Lives of Pyrrhus' and 'Marius' are analysed in terms of the dissatisfaction and insatiable ambitions of their protagonists. The paired 'Lives of Antonius' and 'Demetrius' are discussed in relation to the themes of dissatisfaction, luxurious excess, and the reversal of fortune. The theme of philosophical satisfaction, and the escape from dissatisfaction, are discussed in the context of the 'On Exile' and 'On Tranquility'.
Manual to Automated Testing

Published: November 2021

Purpose - The purpose of this case study is to understand how two organizations view and utilise automated testing and how it relates to the literature. It outlines and discusses the key factors to be taken into consideration when setting up an automated testing, in addition to the risks involved.  Design/methodology/approach – Focus group discussions were executed to collect the data and the findings were compared with other literatures.  Findings – For cognition of automated testing, it is not only limited to its definition and benefits that may be brought into the organization, but also need to focus more on scope of application and preconditions. Aside from the key considerations such as people resistance, working process and training, some other concerns were also found from managerial perspective when adopting automated testing: (1) Cost-benefit – Return of Investment (ROI) is an effective method to analyse the investment, especially for the factors affecting the cost of investment; (2) Management support. It includes balancing between business and technology, management involvement and coordinating the relations between the departments; (3) Tool selection: Choosing the right automation tool is a very complicated process with a lot internal factors involved.  Practical implication – For an organization that doesn’t have automated testing implemented yet, a pilot project can be the first option to understand its practicality and applicability based on individual organizational context.  Originality/Value – This case study can be used for an organization that interests in better introducing and implementing automated testing within the organization.  Key Words – Automated testing, Cost-benefit, Management support, Tool selection, practicality, applicability and ROI.  Paper Type – Case Study Research.
How is Supply Chain Visibility Affecting SME's Operating in International Supply Chains?
Authors:   , Smart Gordon Kenneth
Published: November 2021

Supply chain visibility is generally seen as a positive attribute for individual supply chain partners and the supply chain as a whole. There is limited research on how increasing levels of supply chain visibility can impact individual organizations, particularly smaller entities (SME's). This paper uses an Australasian SME (Orion) as a case study to investigate how increasing visibility is affecting them and the way they operate within international supply chains.  The results indicate that increasing visibility can pose significant challenges and potentially negative consequences for smaller organizations. In addition to the extra resources required and complexity for the SME itself, diverging expectations and a lack of trust between supply partners can negatively impact on supply chain relations and long term supply chain innovation.  Within the supply chains Orion operates, increasing visibility does not appear to be leading to improvements in collaboration, risk sharing or shared goals. Viewed through the lens of Michael Porter's five forces model Orion is in a precarious environment, although there remain options for increased visibility to be used to Orion's advantage.
Dealing with unpredictable risk - The influence of external factors on information systems development and implementations
Authors:   , Esterhuizen Ettiene
Published: November 2021

Organisations and especially Government departments develop information systems for their own specific needs, due to this Government departments invests a great deal in information systems development and implementation projects. The intention is to save on cost and develop information systems according to their needs and requirements. Unfortunately such projects are vulnerable and subject to a range of risks.  This case study identifies the risk factors involved in information systems development and implementation projects and the risk processes that are in place to mitigate against those risk factors. Furthermore the case study investigates an information systems development and implementation project where four legacy systems were to be merged into one newly developed system. The project was interrupted when an organisational merger resulted in the loss of key members of the governance board and the project team, either through redundancy or being allocated other responsibilities within the organisation. This exposed the project to unpredictable risk which caused the project to head down the path of possible failure.  The case study outlines the project plan, what actually happened and what according to the interviewed participants happened during the project. It is clear that the risk management processes wasn't followed and that wrongful decisions were made during the organisational merger. Unpredictable risks as a result of the merger and the decision to continue the project required a strong governance board, proper project management, proper risk management and the execution of the risk management processes. The lack of governance and project management had a huge impact on the project while the loss of expertise and knowledge added to the risk profile which resulted in further complications to the project. It’s during these situation that a strong governance board and proper project management is needed to make those critical decisions and steer the project towards success.
Innovation, Collaboration and New Zealand Public Sector ICT Middle Managers
Authors:   , Jones Suzanne Ellen
Published: November 2021

The case study explores the relationship New Zealand public sector information and communication technology (ICT) middle managers have with innovation and collaboration in relation to an all-of-government ICT strategy. Middle managers are key to implementing ICT strategy, innovation is a stated expectation and collaboration is a critical enabler. The study identified that awareness of the ICT strategy amongst middle managers was lower than desirable, although slightly higher from core public sector managers mandated to follow the strategy. There was not a consistent sense of what innovation is, although managers indicate they are engaging in innovations to quite a high degree. There is a very limited range of stakeholders collaborated with; primarily other agencies, consultants and vendors. This may inhibit potential for innovation that could come from wider engagement. Agencies are exhibiting a narrow view of collaboration and appear reluctant to share resources. Middle managers engage in collaboration and networking within their sector, and appreciate assistance provided by the Government Chief Information Officer, however they also note there is little support provided to collaborate. They would like more forums, facilitators, tools, and policies that support collaboration and systems thinking. The most significant factor empowering middle managers to innovate was the support of their senior manager; however lack of senior manager support was also noted as a significant issue. Primary barriers to innovation were workload and budget, leadership thinking, internal governance mechanisms and risk aversion.
An analysis of the benefits and issues in the development of an Enterprise Data Catalogue
Authors:   , Wang Xuemei
Published: November 2021

Purpose – The purpose of this case study is to examine the rationality for taking an enterprise approach towards metadata’s development. It outlined and discussed the benefits and challenges involved from both theoretical and practical perspectives.  Methodology – The data for this case study is collected through a one on one interview method. The findings were discussed and analysed with other literature.  Findings – Taking an enterprise wide approach towards the development of metadata offers both short-term and long-term benefits to the Ministry. In particular, the short-term benefits include efficiency in time to answer, re-use and re-purposing of existing information. The long-term benefits are the ability to operate at a strategic level with its data and information.  On the other hand, the different level of understanding towards the concept of metadata at present, in addition to a lack of a clear guardianship from a data perspective has lead to challenges in gaining a level of active contribution and ongoing maintenance.  This report suggested that it is essential for the Ministry to maintain a constant marketing style of communication to promote the understanding of the metadata and to incorporate the principle of data stewardship in managing the component of metadata mapping.  Value – This case study provides value by explaining the concept and outlining the key benefits and issues involved to those organisations discovering the topic of metadata management for the first time. This case study adds additional value by offering rare insights into taking an enterprise approach towards the development of a business metadata, offering practical learning and suggestions for other organisations that are embarking on a similar journey.
Organisational and Personal Values Impact on Knowledge Transfer
Authors:   , Hovinga Dany A.
Published: November 2021

This case study research showed that employees’ values were having a greater impact on the transfer of knowledge than those of the organisation. The result was due to limitations faced by employees in adopting organisational values. Semi-structured interviews were carried out to discover employee values and knowledge asset creation behaviours. The interviewees faced difficulties with the organisations knowledge repositories available. The transfer of knowledge was limited within the organisation, which hindered knowledge creation and the interviewees relied on their own values to provide direction to their knowledge actions.
Metaphorical language in second language learners' essays: Products and processes
Authors:   , Hoàng Đoan Hạ Thị
Published: November 2021

This two-phase project investigated metaphorical language use in second language learners’ essays from both perspectives of products and processes. The first phase relied on text analysis to examine the patterns of metaphorical language use in 396 undergraduate essays at four different year levels, focusing on the metaphoricity and the phraseology of their metaphorical language. The study has shown that there were differences in metaphorical language use at different year levels. Metaphorical language use was also found to correlate with writing grades. Conventional metaphorical language use, in particular, significantly explained writing grades.  The second phase explored the learners’ thoughts behind their written production of metaphorical language using data from computer-logged keystrokes and stimulated retrospective interviews. It was found that there was a relationship between the locations and durations of the pauses and the metaphoricity and phraseology of the metaphorical language the participants produced. The study has shown that learners had low awareness of the metaphorical nature of the language they used, and that the underlying thoughts behind their metaphorical language use involved more non-metaphoric than metaphoric thinking.  The project has added new knowledge to current scholarship of metaphor in second language learning and has significant implications for the teaching of L2 vocabulary and writing.
A Study of Unconventional Gas Accumulation in Dannevirke Series (Paleogene) Rocks, Canterbury Basin, New Zealand
Authors:   , Cozens Nick
Published: November 2021

This thesis aims to assess the potential of unconventional gas accumulation of Danevirke aged (65-43 Ma) mudrock of the Canterbury Basin, South Island, New Zealand. Unconventional hydrocarbon resources contained in low-porosity, low-permeability rocks are potentially a large source of natural gas. Recent developments throughout the United States and increasingly so in Australia, signify a shift in exploration efforts from conventional natural gas targets towards unconventional shale gas plays and basin centred gas systems. Despite extensive international progress made in this field of exploration, little is known about New Zealand unconventional hydrocarbon systems.  The Canterbury Basin is approximaty 360,000km² in area and is located approximately between 44°S and 46°S. The deepest part of the basin is located offshore and is known as the Clipper Sub-Basin, which exhibits economic basement depths of 6500m. The Clipper Sub-Basin is a late Cretaceous syn-rift horst and graben feature which trends north east-south west and is bound basinward by the Benreoch High and landward by the Canterbury Bight High. Dannevirke aged transgressive rocks overlay these structures and intermittently exhibit gas-charged intervals in low porosity facies.  Elevated gas concentrations are recorded in four exploration wells in the Clipper Sub-Basin from gas chromatograph readings (up to 2 .7/00.4%). These high-gas zones correspond to intervals of elevated quartz (up to 72wt%), whereas non-gaseous intervals corresponded to quartz values as low as 30wt%. Scanning electron microscopy results do not reveal biogenic silica populations in the cutting samples examined. High silica is related to diagenetic silica transformations of mica, various clay minerals, pyrite and silica transformations. Although no visible porosity is observed in thin sections, FMI wireline analysis illustrate natural fractures predominately occur in siliceous intervals, where resistive fractures can account up to one fracture per 10m of stratigraphic thickness. These fissile or laminated brittle lithologies are likely hydrocarbon conduits or accumulation intervals for wet gas. RockEval pyrolysis results indicate the siliceous mudrocks are organic le-n, comprising an immature gas-prone source rock which averages 1.5% total organic carbon.  Findings made in this research are compared to the. Whangai Formation, considered in this study to be a comparable shale gas system and also to the Monterey Formation of the United States which is a known basin centred gas system. Dannevirke aged sediments found in the Clipper Sub-Basin appear to constitute the requisites of a near-to-source, direct type., basin centred gas system. Implications of this study open up the possibility that New Zealand's widespread Paleocene-Eocene mudrocks are capable of natural gas accumulation and therefore viable natural gas exploration targets in New Zealand.
The Forgotten Soundtrack of Maoriland: Imagining the Nation Through Alfred Hill’s Songs for Rewi's Last Stand
Authors:   , Cross Melissa
Published: November 2021

Alfred Hill’s songs based on collected Māori musical materials and narrative themes are artefacts of cultural colonisation that represent individual identities and imagined communities. They are tangible evidence of the site of identity formation known as Maoriland within which Pākehā construct imaginings of ‘Māoriness’ to create their own sense of indigeneity and nationhood. Although early twentieth-century Maoriland has been discussed widely in the arts and literature, scholars have not addressed the music of Maoriland, perhaps because it is heard today as the cultural form that most clearly expresses racialised sentimentality and colonial hegemony. However, Maoriland music can tell us much about New Zealand society if it is recognised as inhabiting an ‘in-between’ place where Pākehā fascination for the racial other was often inseparable from an admiration for Māori promoted by a knowledgeable group of Māori and Pākehā cultural go-betweens.  This thesis presents a critical cultural analysis of the ethnic, racial, gendered, and national identities represented in Hill’s ‘Māori’ songs, viewed through the lens of his use of these in his score for Rudall Hayward’s film Rewi’s Last Stand (1940). This analysis shows that these popular songs contributed, and continue to contribute, to the nexus of Māori, war, and music in Pākehā narrations of the nation. By applying a bicultural approach to the study of Hill’s Maoriland songs, this research also shows these ‘in-between’ songs represent individual, tribal, and national Māori identities too. While this work adds music to the discourse of Maoriland, and Maoriland to the discourse of New Zealand music and national identity, Hill’s ‘Māori’ music, early twentieth-century New Zealand music, and New Zealand film music all remain severely under-researched areas of New Zealand music studies.
The Development of a Low-Cost Microfluidic Magnetic Separation System
Authors:   , Smith Geoffrey
Published: November 2021

Microfluidic systems show excellent promise for analytical applications, due to their ability to rapidly process minute sample quantities with high sensitivity. At the same time, functionalised superparamagnetic magnetic microbeads and nanoparticles have emerged as useful substrates for biomedical applications such as bioassays, fuelling research into tools for the manipulation of magnetic particles in microfluidic channels. This thesis describes the design, fabrication and evaluation of microfluidic systems for the separation of magnetic microbeads and nanoparticles. Microfluidic devices were produced in polydimethylsiloxane using a low-cost rapid prototyping process. Channels 300μm or greater in width were accurately reproduced using this method. Laminar flow was observed in the channels of these devices, allowing two-phase flow to be used for separation purposes. Magnetic field gradients of 25-500 T/m were generated in the microchannels using either permanent magnets or soft magnetic materials. The performance of a permanent magnet-based separation system was evaluated, and it was found that the system could extract magnetic microbeads with an efficiency of up to 75%. A limited ability to separate magnetic microbeads on the basis of magnetic moment and/or particle size was also demonstrated.
Narratives of human trafficking: Defining policy, practice and positioning in a contested field
Authors:   , Cornforth-Camden Bryony
Published: November 2021

This research uses narrative criminology to investigate the way the problem of human trafficking is narrated in New Zealand and international settings. It draws on accounts from professionals who are responsible for defining and responding to human trafficking, and reports, policy, and other guiding documents. The main issue driving this research is the contested nature of human trafficking. Human trafficking is a crime type that has been highly politicised resulting in shifts and changes to the way the problem of trafficking has been approached over the past 20 years, with differing trends coming to the fore and dominating trafficking practices at different times. The internationally dominant approaches which emphasise prostitution, harsh criminal responses, and border security have come under criticism for having harmful impacts for migrant workers. This research aims to understand how human trafficking is defined, what discourses are drawn on, and how international narratives may be influencing local responses with the overall aim of identifying new and less problematic ways of conceptualising human trafficking and responding to migrant exploitation.

This thesis finds that different ways of narrating human trafficking are constitutive of different trafficking realities. Narratives determine the shape the problem takes, who is involved, what the causes and solutions are, who responds, and who are classed as victims and perpetrators. This research concludes that as narratives structure reality and action, in order to change how we deal with certain problems, the way the problem is narrated must also change.

The findings of this thesis reflect current challenges in the wider international anti-trafficking field of how to avoid positioning western states and systems as outside of the problem of trafficking, issues with broadening definitions of victimhood, and questions of the role of international versus local bodies in defining problems involving migration and crime. As well as reflecting these current challenges, the findings from this research provide insights for moving forwards by proposing an alternative narrative. This counter narrative is created through drawing together components of narratives identified in this research. It avoids the issues of western exceptionalism, narrow forms of victimhood, and a focus on sex trafficking, and provides a different method for conceptualising migration, exploitation, and harm.
A Critical Study of Kumpulan Militant Malaysia, its Wider Connections in the Region and the Implications of Radical Islam for the Stability of Southeast Asia
Authors:   , Mohammad Aslam Mohd Mizan
Published: November 2021

This study analyzes the existence and political history of Kumpulan Militan Malaysia (Malaysia Militant Group-KMM); the most spectacular Muslim militant group to recently emerge from Malaysia. Using an interpretive framework derived from typology of radicalism, this study exposes the roots of the group and its transformation into a militant movement. Based on extensive fieldwork, numerous interviews and in-depth research of related documents, this study demonstrates that the existence of KMM cannot be dissociated from Afghanistan’s global Jihadist campaign.  This study analyzes the activities of KMM in the context of radical Islam in the South East Asia region and its wider connection, particularly with the Jemaah Islamiyah (JI). Findings from fieldwork research conducted with active and ex-members of KMM and JI are presented to find the answer to the question pertaining the involvement of these two groups in terrorism activities in Southeast Asia.  Southeast Asian contemporary social and political scenarios have been build-up from a long history of rebellious freedom fighters against colonial super-powers. In addition to nationalism, Islamization has also played a significant role in establishing freedom movements in the 1940s and 1950s. Systematic pressure under colonial powers and harsh policies implemented by ultra nationalists to these groups resulted in a series of rebellions and defiance such as what happened in Indonesia, Southern Thailand and the Southern Philippines. Historical facts led to radicalism in these countries, which are important for gaining a better knowledge about Muslim radicalism in Southeast Asia also presented in this thesis.  The ‘typology of radicalism’ - the transformation from ‘nominal believers’ to activists, extremists, radicals and terrorists is explained in this research. Understanding Islam and their willingness to perform Jihad as was carried out in Afghanistan has had a significant impact on today’s militants. Finally, this research suggests the best methods for overcoming radicalism and diffusing KMM and JI’s threat in Southeast Asia.
The Design of an IEEE 1588 End-to-End Transparent Ethernet Switch
Authors:   , Gordon Caleb
Published: November 2021

In measurement and control systems there is often a need to synchronise distributed clocks. Traditionally, synchronisation has been achieved using a dedicated medium to convey time information, typically using the IRIG-B serial protocol. The precision time protocol (IEEE 1588) has been designed as an improvement to current methods of synchronisation within a distributed network of devices. IEEE 1588 is a message based protocol that can be implemented across packet based networks including, but not limited to, Ethernet. Standard Ethernet switches introduce a variable delay to packets that inhibits path delay measurements. Transparent switches have been introduced to measure and adjust for packet delay, thus removing the negative effects that these variations cause.  This thesis describes the hardware and firmware design of an IEEE 1588 transparent end-to-end Ethernet switch for Tekron International Ltd based in Lower Hutt, New Zealand. This switch has the ability to monitor all Ethernet traffic, identify IEEE 1588 timing packets, measure the delay that these packets experience while passing through the switch, and account for this delay by adjusting a time-interval field of the packet as it is leaving the switch. This process takes place at the operational speed of the port, and without introducing significant delay. Time-interval measurements can be made using a high-precision timestamp unit with a resolution of 1 ns. The total jitter introduced by this measurement process is just 4.5 ns through a single switch.
Synthesis and Thermal Treatment of Lithium- and Magnesium-Containing Geopolymers
Authors:   , O'Connor Sean
Published: November 2021

Geopolymers are a class of cementitious aluminosilicate materials that are receiving an increasing amount of attention due to their potential applications in toxic waste remediation and as construction materials. They are composed of a network of crosslinked silicate and aluminate tetrahedra with charge-balancing alkali cations and are therefore similar in composition to alkali aluminosilicate zeolites. They are, however, x-ray amorphous.¹⁻⁴ They are formed by the dissolution of a solid aluminosilicate in a solution of alkali hydroxide or alkali silicate to form aluminosilicate ions which subsequently polymerise.  The effects of adding magnesium to metakaolin geopolymer systems was examined. Magnesium was added as soluble magnesium salts and as magnesium oxide and hydroxide. When added as a soluble salt, an amorphous magnesium (alumino)silicate with a lower degree of silicate polymerisation than a geopolymer is formed. When added as the oxide or hydroxide, hydrotalcite is formed. In both cases, the product is produced alongside a separate geopolymer phase. A magnesiumcontaining geopolymer phase was not found in either. When heated to 1200°C, geopolymers with magnesium oxide added bloated to form lightweight foams.  Lithium analogues of conventional metakaolin geopolymer systems with a range of lithium, aluminium, silicon and water contents were examined. Systems with molar ratios similar to those of commonly studied sodium and potassium metakaolin geopolymers produce self-pelletised lithium zeolites. The zeolite formed was Li-EDI, the lithium analogue of zeolite F. This is the first reported synthesis directly from metakaolin. True lithium geopolymers are found not to form in the systems examined. The zeolite bodies react to form β-eucryptite and β-spodumene at temperatures from 800 – 1350°C.  The use of aluminium hydroxide and amorphoud silica rather than aluminosilicates as raw materials for the formation of potassium geopolymers was found to produce geopolymers with embedded grains of unreacted silica and aluminium hydroxide.
Synthesis of N-glycans implicated in asthma and allergy
Authors:   , Haslett Gregory William
Published: November 2021

Asthma and allergies affect a large number of people, with over 300 million people worldwide suffering from asthma alone. Although, on the ‟macroscopic‟ level, it is known how allergens trigger allergic reactions, it is not known how an allergen's ‟micro‟ structure causes such a profound allergic response in sensitised individuals. A review of inter-species carbohydrate motifs revealed a striking similarity between carbohydrate moieties (N-glycans) present on antigens derived from species known to give an allergic T helper (Th) 2 response in humans (such as pollen, schistosomes, and food allergens). Preliminary studies on mixtures of allergen extracts have suggested that these carbohydrate motifs (glycoproteins) bias the immune response to an allergic (Th2) response.  This project presents work conducted towards the synthesis of three fragments of a larger N-glycan found on allergens. The synthesis of these N-glycans will allow the first detailed study regarding the relationship between N-glycan structure and Th2 bias to be performed and thereby aid in our understanding of the molecular triggers of asthma. Ultimately, this could lead to the elucidation of the mechanisms of the allergic Th2 immune response.
Implementation of Winnowing Algorithm and Simple Additive Weighting SAW for Publication Reference Journal Search System
Authors: Fakhruddin Imam , Anugrah Indra Gita
Published: November 2021

Reference journals have several different writing arrangements. In the reference journal, there is some information or words needed in making scientific journals. With this information or word retrieval system, it can help to find journals that match the similarities between input and information or words in the journal that will be used as a reference. In this study, the input process of equations and information or words will be processed using the Winnowing algorithm as an algorithm that can find the similarity of words or texts with N-gram functions, rolling hash, and Jaccard Coefficient. In general, the search only uses the same words or text without any weighting on the composition of the reference journal. To be able to find journals and their level of importance in the order of journals, a weighting method is needed. This study also uses the Simple Additive Weighting (SAW) method as a process to determine the value of the order of urgency in journals so that it can provide results in the form of rankings based on searches and urgency weights in reference journals. The results of the similarity query with documents obtained 60% precision, 77% recall, and 81% accuracy, documents, and documents had 41% precision, 83% recall, and 66% accuracy. using Winnowing Algorithm, the search system can detect the similarity of text.

Desde un enfoque dialectológico y etnográfico, en la presente investigación se describen y analizan algunos esquemas culturales del campesinado colombiano asociados a la brujería. Usando el Atlas lingüístico etnográfico de Colombia (1954-1983), este trabajo contrasta los materiales lingüísticos de los archivos sonoros con los mapas lingüísticos. Se adopta el concepto de “etnotextos” para profundizar en la lógica discursiva de las fuentes orales, y de los esquemas culturales a fin de dar cuenta de las experiencias y significados campesinos sobre la brujería en Colombia.
Mary Shelley e a Sibila de Cumas
Authors: Soares Janile

No ano de 1826 a escritora inglesa Mary Shelley publica o romance apocalíptico The Last Man, contando a história de como a humanidade fora dissipada por uma peste em 2100, restando apenas um sobrevivente que, imune à pandemia, resolve deixar registrado em forma de diário, a história do fim do mundo como ele o conhecia. Ao apresentar o relato que levou à escritura da narrativa, Mary Shelley nos coloca em contato com o mito da Sibila de Cumas, revelando ter encontrado o manuscrito que indicava os fatos que ela narrou em seu romance. Este artigo visa discutir a importância do texto introdutório do romance, considerando as molduras estabelecidas entre o mito da Sibila e as capacidades criadoras de Shelley.

Autora de uma bibliografia extensa, Nélida Piñon é ainda uma escritora ainda pouco estudada e pouco citada nos estudos literários brasileiros, oscilando entre períodos de maior fulgor e outros de menor brilho. A crítica movimenta-se em um sobe e desce de opiniões; as histórias da literatura brasileira, publicadas a partir da década de 1960, praticamente desconhecem seu nome. Este texto analisa os principais comentários críticos e procura levantar hipóteses para o silenciamento sobre a obra de Nélida Piñon

This research aims to describe and classify the language used by Arab Embong Community in their daily life.  Language and society always influence each other. The development of language is also along with the development of society. Therefore the study of sociolinguistics as a scientific discipline in which studying language in relation to society is always interesting. The problem in this study is the language used by Embong Arab Community which is an immigrant Arab Community in Malang. This was a field research with a qualitative descriptive method which was investigated using the Diglossia theory. The methods of data collection were observation and interview. The results of this research indicated that the Embong Arab community used three languages, namely Fusha and Amiyah Arabic, Indonesian and Javanese. The three languages were used interchangeably according to the purpose of communication. Fusha Arabic, as the official and unifying language among Arabs, was rarely spoken. They preferred to choose Amiyah Arabic to communicate as a non-standard language variety. However, their Amiyah language was different from the Yemeni Arabs in general. This was due to their long-standing interactions with the local population. The unique thing was that even though they were of Arab descent, due to their high level of interactions with the local population, they often used non-formal Indonesian and Javanese Ngoko in their daily lives. So there were two varieties of diglossia in Embong Arab Community, namely high level language consisting of Fusha Arabic and formal Indonesian and low level language consisting of Amiyah Arabic, non-formal Indonesian and Javanese Ngoko).

This research is studying about one of the most important skills in the Arabic language that is hoped to be acquired by Malaysian students, either in secondary or university level. The aim of teaching essay writing at these two stages is to enable students to express a topic in writing in a good manner and in an organized manner of various kinds according to the correct rules of the Arabic language. It is noticeable that non-Arabic speaking students, especially Malaysian students, despite their mastery of grammatical and morphological rules, still fall into stylistic errors resulting from their lack of understanding of the ‘ibarāt al rābitah (conjunctive phrases), their connotations and their functions in structural writing. Based on all of the foregoing, this research deals with theories related to the concept of stylistic errors and the concept of style and its elements, especially in the field of teaching Arabic as a second language. The research followed the descriptive and analytical method and was limited to analysing the ‘ibarāt al rābitah (conjunctive phrases) in the modern Arabic language and analysing their meanings, functions, and uses in structural writing. The research has reached many results, the most important of which is ‘ibarāt al rābitah (conjunctive phrases) as one of the most important elements of the Arabic language style that is hoped to be provided to Malaysian students, especially in the secondary and university degree stage, to control the stylistically sound structural writing. The research also stated some recommendations to facilitate the teaching and application of ‘ibarāt al rābitah (conjunctive phrases) at the secondary and university levels.
