Optimisation of parametric equations for shock transmission through surface ships from underwater explosions
Creators: name: Elder, David
Publisher: name: RMIT University
Year: 2024

description: Currently shock effects on surface ships can be determined by full scale shock trials, Finite Element Analysis or semi empirical methods that reduce the analytical problem to a limited number of degrees of freedom and include hull configurations, construction methods and materials in an empirical way to determine any debilitating effects that an explosion may have on the ship. This research has been undertaken to better understand the effect of hull shape on surface ships' shock response to external underwater explosions (UNDEX). The study is within the semi empirical method category of computations. A set of simple closed-form equations has been developed that accurately predicts the magnitude of dynamic excitation of different 2- D rigid-hull shapes subject to far-field UNDEX events. This research was primarily focused on the affects of 2-D rigid hull shapes and their contribu tion to global ship motions. A section of the thesis, "T-Joint", considers the exacerbating affects that shock wave propagation has on a typical Glass Reinforced Polymer (GRP) laminated ship T-Joint with respect to its strength and the transmission of the shock to the adjacent bulkhead. The hull motion parametric equations developed in this research are compared against computational fluid structure interaction predictions obtained from non-linear, explicit finite Element (FE) simulations using -the LS-Dyna code. The equations are shown to predict the vertical acceleration and velocity of four basic hull shapes to within approximately ±15% of the - FE model results. Addition error estimates obtained for sensitivity analyses, predicted that the LS-Dyna simulations were accurate to within ±11 % when compared to real UNDEX events. The resultant error of the closed-form solutions compared to real UNDEX events is the summation of the two error estimates at ±26%. A number of different GRP T-Joint geometries were r anked with respect to their capability of withstanding UNDEX shock loading, the study included three basic geometries, allowing for the affects of non-monolithic construction due to jointing methods and material strain rate considerations. The study concluded that two of the joint geometries: the 45° chamfered and the 40 mm fillet preformed significantly better that the 22.5° chamfered geometry.
Women and community development in India: examining the paradoxes of everyday practice

description: My experience as a development aid worker has brought to the fore the incongruence between the rhetoric and practice of community development in India, more so in relation to women. Historically, the practice of community development in India has also been imposed and could be considered as an 'imperialist' relic of the colonial rule. This has been traced through an extensive literature review and discourse analysis of the five year plan and other related documents.

The research aimed to uncover the manner in which rural Indian women engaged with structures and processes of community development and to explore what benefits or otherwise accrued to them. It further sought to explore the reasons for the failure of a particular program as envisaged by local women. The thesis used the framework of structuration, everyday life and community development theories (Giddens, Lefevbre, de Certeau, Ife) and an ethnographic methodological approach. One rural community of 52 households, in the state of Orissa (India) was the subject of study and in-depth interviews were conducted with three key informants.

Participant observation was the cornerstone of this research in order to gain an in-depth view of the everyday lives of women, with the researcher spending seven months in the community. Themes were developed around the community development program (Mahila Mandals) and the key informants were interviewed regarding the same, its formation, structure, processes, the reasons for its initial success and subsequent failure and finally women's agency in engaging with various aspects of the program.

The findings showed that this program would not have developed unless it had been driven from the top; women had no say in the structures and processes, and while it was successful initially for instrumental reasons, not taking into account women's agency was the reason for its downfall. Despite these lessons, it is recognised that the practice of community development continues to remain top-down. Till date, international aid agencies, government's (national, state and local), and/or INGOs/ NGOs that determine the needs of the communities and the approaches to addressing and evaluating them.

Conclusions include a policy discussion on the attempt by international agencies, especially DFID, and governments (of India and Orissa) to address gender issues in their existing and new programs taking into account women's agency as constructed in their everyday lives. There is an agreement with the international, national and local debates that gender issues have to be addressed with great urgency in view of the changing roles of women.

description: The activities, described in the present paper, have been conducted in the framework of the HYPROB Program, carried out by the Italian Aerospace Research Centre (CIRA) under contract by the Italian Ministry of Research (MIUR). The Program has the main objective to enable and improve National system and technology capabilities in the field of liquid rocket engines (LRE) for future Space Propulsion Systems and applications, with specific regard to LOX/LCH4 technology. Moreover, the Program is in coherence with the long-term vision, provided by the Italian Space Agency (ASI) on Space Propulsion. According to the last implementation of the program, a system line, named \"HYPROB-DIMOSTRATORI\", has been included: it aims at designing, manufacturing and testing LRE demonstrators, LRE and HRE breadboards. The main objective of this line is to design, manufacture and test a regeneratively cooled LOX/LCH4 demonstrator, a pressure-fed thrust chamber assembly (TCA), aiming at validating critical design and technology features and then assessing the technology readiness level of potential solutions for future engines. The present paper illustrates the advancements in the development of the demonstrator. In particular, the cold and hot testing activities for the design validation of the injector head will be presented. Moreover, technological and manufacturing issues for the combustion chamber manufacturing will be exposed by giving details about the experimental activities recently performed.

description: To provide constraints on the chemical processes responsible for the observed columns of organic species, we used NOEMA to observe the sight line toward NRAO150 in the 2mm spectral window. We targeted the low excitation lines of o-H2CO 2(1,1)-1(1,0) and p-H2CO 2(0,2)-1(0,1) as well as the nearby transitions of CS(3-2) and c-C3H2. We combined these data with previous observations to determine the excitation conditions, column densities, and abundances relative to H2 in the different velocity components. We performed non-LTE radiative transfer calculations including collision cross sections with ortho and para H2 and with electrons. New collision cross sections with electrons were computed for ortho and para formaldehyde. The c-C3H2 line profiles are very similar to those of HCO+ and CCH, while the CS absorption features are narrower and mostly concentrated in two main velocity components at V = -17 and -10 km/s. H2CO absorption lines present an intermediate pattern with absorption in all velocity components but larger opacities in the two main velocity components. The ortho-to-para ratios of H2CO and c-C3H2 are consistent with the statistical value of 3. While the excitation temperature of all c-C3H2 velocity components is consistent with the CMB, the two strong components detected in CS show a clear excess over the CMB indicating that CS resides at higher densities than other species along this particular sightline, n(H2) ~ 2500 cm-3 while n(H2) < 500 cm-3 for the other velocity components. We detected faint absorption from o-H213CO and C34S allowing us to derive isotopic ratios: o-H2CO/o-H213CO = 61 and C32S/C34S = 24. The excitation of the 4.8GHz line of formaldehyde is sensitive to the electron fraction and its excitation temperature is predicted to be lower than the CMB at low and moderate electron fractions, x(e)< 6E-5, and to rise above the CMB at high electron fractions, > 1e-4.

Marked body surface: lived experiences of women with non-facial scars
Creators: name: Kofman, Lee
Publisher: name: RMIT University
Year: 2024

description: This exploratory study examines the lived experiences of women with non-facial scars. The number of people living with scars is significant. In contemporary western culture scars are seen as disfigurements and having them can result in negative consequences for their bearers. However, while the psychosocial impact of facial scars have attracted some research interest, non-facial scars as a unit of analysis have rarely been investigated.

This study uses a mixed methods design that is predominantly qualitative and supplemented by quantitative measures where appropriate. It is underpinned by the constructivist grounded theory as developed by Kathy Charmaz. In-depth semi-structured interviews were conducted with thirty women with non-facial scars. The interviews were supplemented with other data collection methods: creative methods involving photography and writing, and two ordinal scales.

The main aim of this study was an open exploration of women’s experiences of their scars, which will also be reflective of the context in which participants live and the social processes involved in these experiences The substantive theory that emerged conceptualises non-facial scars as marks that can be disfiguring, can be socially interpreted as shedding light on their bearers’ life stories and personalities, and can also contain personal meanings for their bearers, such as memories and being identity markers. Findings also show that the experiences of non-facial scars can be viewed as complex and ambivalent. Non-facial scars can have a profoundly positive and/or negative impact on women’s identities, thoughts, emotions, social interactions and private behaviour. They can adversely affect women’s life choices and, to some extent, their life chances. However, women can also be creative at how they interpret, manage and utilise these bodily features which culturally are considered to be disfiguring.

description: The majority of massive stars are expected to exchange mass or merge with a companion during their lives. This immediately implies that most supernovae (SNe) are from such post-mass-exchange objects. Here, we explore how mass accretion and merging affect the pre-SN structures of stars and their final fates. We use the stellar evolution code MESA, infer the outcome of core-collapse using a neutrino-driven SN model, and apply a rapid-accretion model. Our models cover initial masses from 11 to 70 Msun and the accreted mass ranges from 10-200% of the initial mass. We find that mass accretion in particular onto post-main-sequence (post-MS) stars can lead to a long-lived blue supergiant (BSG) phase. In comparison to genuine single stars, post-MS accretors have small core-to-total mass ratios, regardless of whether they end their lives as BSGs or cool supergiants (CSGs), and they can have genuinely different pre-SN core structures. As in single and binary-stripped stars, we find black-hole (BH) formation for the same characteristic CO core masses M_CO of ~7 Msun and >13 Msun. In models with the largest mass accretion, the BH-formation landscape as a function of M_CO is shifted by about 0.5 Msun to lower masses. We find a tight relation between our neutron-star (NS) masses and the central entropy of the pre-SN models, suggesting a universal relation that is independent of the evolutionary history of stars. Post-MS accretors explode both as BSGs and CSGs, and we show how to understand their pre-SN locations in the Hertzsprung--Russell diagram. Some BSGs that avoid the luminous-blue-variable (LBV) regime are predicted to collapse into BHs of up to 50 Msun while others explode in supernovae and eject up to 40 Msun, greatly exceeding ejecta masses from single stars. These masses can be even higher at lower metallicities, and they may fall into the pair-instability-supernova mass gap. [abridged]

Improving project management practice in Ghana with focus on agriculture, banking and construction sectors of the Ghanaian economy
Creators: name: Amponsah, Richard
Publisher: name: RMIT University
Year: 2024

description: Project failure rates and associated resultant cost in Ghana has been a major concern in recent times (AfDB, 2006). Reasons mostly assigned were unreliable for lack of empirical evidence. Generally, literature provided certain reasons but most often these researches were carried out in environments that were totally and entirely different from that of the Africa’s and Ghana’s conditions.

Over the years, considerable effort had been made in trying to find out why projects and programs fail in Ghana (Ofori, 2006; Ayee, 2000). Projects and Programs failures in Africa are visible all over the place arguably though, account for our underdevelopment. This research was a perception study which identified and analyzed the potential project failure/success factors (project critical factor(s)) in three (3) selected sectors‐Agriculture, Banking and Construction of the Ghanaian economy. The study also identified project management tools and techniques whose application(s) were familiar to the Ghanaian project practitioners and were associated with project outcomes (success/failures). The above studies employed mainly quantitative research approaches by designing an independent (project factors)‐dependent (project success criteria) variable linear model. Multivariate Analysis of Variance for statistical analysis is considered appropriate. A survey of 324 project practitioners was conducted in the three sectors focused on answering the research questions and testing hypotheses.

The analysis revealed perceived project critical factors specific to projects of each sector as well as critical factors common to project organizations of some of the sectors.

Project management maturity of project organizations of the three sectors were also assessed through a qualitative research approach with the help of the Capability Maturity Model Integration (CMMI). The Process areas used for the assessment included Requirement Management, Project Planning, Monitoring and Evaluation; Measurement and Analysis; and Product and Process Quality Assurance. It was observed that with the process areas used as the criteria for assessment, 90% and more of the project organizations assessed were in the level 2 and lower of the Capability Maturity Model (CMMI). In other words a very few organizations were even close to the level 3 of the CMM. This called for a recommendation to the organizations for improvement in their project management activities.

description: We present a high angular resolution multi-wavelength study of the massive globular cluster NGC 1835 in the Large Magellanic Cloud. Thanks to a combination of optical and near ultraviolet images acquired with the WFC3 on board the HST, we performed a detailed inspection of the stellar population in this stellar system adopting a ``UV-guided search'' to optimize the detection of relatively hot stars. This allowed us to discover a remarkably extended horizontal branch (HB), spanning more than 4.5 magnitudes in both magnitude and colour from the region redder than the instability strip, up to effective temperatures of 30,000 K, and including a large population of RR Lyrae (67 confirmed variables, and 52 new candidates). This is the first time that such a feature has been detected in an extra-Galactic cluster, demonstrating that the physical conditions responsible for the formation of extended HBs are ubiquitous. The acquired dataset has been also used to redetermine the cluster distance modulus, reddening, and absolute age, yielding $(m-M)_0=18.58$, $E(B-V)=0.08$, and $t=12.5$ Gyr, respectively.

description: A reliable prediction of the physical phenomena of cryogenic propellants including phase change is of major interest to enable cost effective launcher developments. The availability of appropriate experimental microgravity data is crucial and for LH2 very hard to find. In the present paper experimental data obtained from drop tower tests using liquid hydrogen are being compared to numerical analyses. A quantitative comparison of the experiment is done. In conclusion it can be stated that the temperature evolution is qualitatively well captured. Further improvements are however necessary with respect to phase change and contact angle modelling.

Enabling systemic conversations: exploring the role of design in strategy implementation
Creators: name: Stewart, Nigel
Publisher: name: RMIT University
Year: 2024

description: This research set out to investigate how project teams can facilitate what I term Systemic Conversations where the implications and consequences of new ideas are surfaced for deliberation. Conversations that go beyond the design of new ideas to the messy space of implementation where a myriad of decisions are made to ensure the new idea is effectively designed and integrated into an organization’s chosen way of working and thinking. Conversations, which I found difficult to initiate in my 17 years in various business roles and where I found the tools, thinking and methods from my own business paradigm insufficient.

For this investigation I looked to the field of design for answers and worked as an embedded researcher within two design teams. Design is a field that in recent years has made inroads into both the business literature and its practices around innovation and ideation and I wanted to explore what it could offer in the field of implementation. I spent 18 months participating, observing and reflecting on the design team’s methods, tools and way of thinking; how they did or did not respond to the systemic issues that arose and what leverage if any this discipline could offer to this business challenge.

Through this investigation I learnt that design did have agency in this implementation space but this space was not an easy fit with all designers. Implementation challenged values and practices that make design so successful in the innovation arena. Importantly this research revealed that enabling systemic conversations required deeper fundamental changes to the way we work beyond merely defining steps and processes to facilitate these conversations. That in order to surface and work with systemic issues there had to be eight enabling conditions presents. These conditions could only be created through understanding and changing the way we think about task (doing), skill (knowing & thinking) and paradigm (valuing and believing). That in order to surface and work with systemic issues, both business and design needed to examine their existing practices and to develop new models with which to facilitate systemic conversations. These insights have implications for how we educate business and design students to not only see systemically but how to appreciate and capitalize on each other’s strengths.

description: Hybrid rocket propulsion has several advantages over liquid and solid systems such as safety, thrust control capability and fabrication and operational costs. However, the primary disadvantage of conventional hybrid rocket systems is the low regression rate of the solid fuel grain and then a rather low ISP. A remarkable improvement on fuel regression rate was obtained by using solid paraffin that burns three to four times faster than traditional hybrid fuels, such as HTPB. A great number of studies have searched means to increase fuel regression rate by using performance-enhancing materials such as aluminium or by changing the oxidizer injector geometry. In this work, we apply a pressure swirl atomizer in a lab-scale hybrid rocket, based on N2O-Paraffin propellants, in order to study the effect of the injector system on the solid fuel regression rate. A 20% increase in paraffin regression rate was obtained compared to direct injection systems (showerhead).
Use of remote sensing data for broad acre grain crop monitoring in Southeast Australia
Creators: name: Coppa, Isabel
Publisher: name: RMIT University
Year: 2024

description: In 2025, there will be almost 8 billion people to feed as the worlds population rapidly increases. To meet domestic and export demands, Australian grain productivity needs to approximately triple in the next 20 years, and this production needs to occur in an environmentally sustainable manner. The advent of Hi-tech Precision Farming in Australia has shown promise in recent time to optimize the use of resources. Most 'precision farmers' produce yield maps at harvest. However when yield maps become available it is usually too late to apply management techniques that would address problems in the crop specific to the current season.

A satellite-based broad-acre crop monitoring system could provide intelligence on crop performance throughout the growing season. A prototype concept for a system that used commercially available satellite imagery was developed in this research, named ALMIS (Agricultural Land Management Information System) and tested with 25 farmers in the Gooroc area in Victoria with a focus on the following crop types; barley, canola, chickpeas, lentils and wheat. Through the study, several components providing vital information for a crop monitoring system were developed from satellite imagery, including crop type discrimination, quantitative crop parameters, crop yield estimates. Furthermore, critical parameters for the system were determined.

The feedback given by the Gooroc farmers, together with the results gained from the ALMIS field studies and considerations reported in the literature were the foundations for the concept design proposal. As critical parameters were identified (amongst others): delivery of data within 1-2 days after acquisition; data should have spatial resolution better than 10 meters, and appropriate geometric and radiometric stability; in an easy-to-use computer interface (software or via internet), carefully timed image data should be offered as near infrared imagery, colour-coded vegetation index, percentile rating for each paddock, quantitative vegetation parameter and yield forecast maps; assistance should to be given to farmers by trained agronomists to convert information into management decisions, and training courses are needed to give end users basic understanding of the technologies utilized by such a system; consolidated strategic development efforts need to be employed to further the use of the information in decision support systems and variable rate technology. As the technology is in its infancy it needs to be supported by government and industry initiatives to reach critical mass.

It was concluded that information from satellite remote sensing is greatly beneficial to the farming community of south east Australia, resulting in substantial economic benefits for local farmers as it becomes widely adapted. The technology developed in this thesis contributes to the Australian goal of increasing crop yields in a profitable and environmentally friendly manner.

description: Clusters of galaxies are turbulent environments, whether merging systems with a turbulent intracluster medium (ICM) or relaxed systems sloshing within the potential well. In many such clusters, diffuse radio sources associated with the ICM are found: radio haloes and mini-haloes. Abell 2142 is a rich cluster undergoing extreme core sloshing, generating four cold fronts and a complex multi-component radio halo. Recent work revealed three halo components which span 2.4 Mpc. Particle acceleration on such scales is poorly understood, and requires high-quality multi-frequency data to understand. We use new deep MeerKAT L-band (1283 MHz) observations, combined with LOFAR HBA (143 MHz) data and X-ray data from XMM-Newton and Chandra to study the spectrum of the halo and the connection between the thermal and non-thermal components of the ICM. We detect the third halo component for the first time at 1283 MHz and confirm its ultra-steep spectrum nature, recovering $α_{\rm H3, total} = -1.68 \pm 0.10$. All components follow power-law spectra which steepen toward the cluster outskirts. We profile the halo along three directions, finding evidence of asymmetry and spectral steepening perpendicular to the main axis of the cluster. Our thermal/non-thermal investigation shows sub-linear correlations that are steeper at 1283 MHz than 143 MHz, and we find different connections in different components of the halo. We find both a moderate anti-correlation (H1, the core) and positive correlation (H2, the ridge) between radio spectral index and X-ray temperature. Our results are broadly consistent with an interpretation of inhomogeneous turbulent (re-)acceleration. However, the anti-correlation between radio spectral index and X- ray temperature in the cluster core is challenging to explain; the presence of three cold fronts and a generally lower temperature may provide the foundations of an explanation.

Virtual teamwork and human factors: a study in the cross-national environment
Creators: name: Chou, Yu-Min
Publisher: name: RMIT University
Year: 2024

description: There has been considerable research on technical aspects of virtual teams, such as the use of collaborative technologies and computer mediated communication. By contrast, little research has focused on the human aspects of virtual teams such as the way team members cooperate in the context of cross-national boundaries. This study addresses this gap in the literature by exploring key human factors that may influence virtual teams working in the cross-national environment. It intends to answer the two central research questions. 1) What are the main human factors affecting the virtual teamwork in the cross-national environment? 2) Do those human factors have the influential effects? Why or why not? The study applies the Hackman and Morris's (1975) inputs-processes-outputs (l-P-O) model and discusses relevant theories, such as Bundura's social cognitive theory, Nonaka's socialisation, externalisation, combination and internalisation (SECI) knowledge transfer model and Fishbein and Ajzen's theory of reasoned action (TRA), to build the research framework that identifies a number of important human factors affecting virtual teamwork, including individual competencies, knowledge sharing willingness and behaviour, members satisfaction, communication, trust, and leadership. By using the triangulation mixed method, combining both quantitative and qualitative approaches, this study comprehensively discusses research findings to construct a model of multinational virtual teamwork. Research findings can help to fill the gap in academic research and also provide practice applications in business companies.

description: Hot structures made of Ceramic Matrix Composites (CMC) for space re-entry vehicles play a key role regarding the feasibility of advanced and reusable space transportation systems. In particular, looking to IXV experience and SPACE RIDER requirements, the need of a hot primary structure for the control surfaces is mandatory. In this framework, the validation with in-flight data of numerical tools capable to predict thermal and mechanical behaviour of a CMC component is of outmost importance. Scope of the paper is to present a finite element model for thermal and thermo-mechanical analyses of TPS components and its validation with IXV temperature data measured during the successful flight of 11 February 2015.

description: In the current work a URANS model of a single injection element is employed to study the response of a single coaxial LOx/GH2 injection element to an imposed acoustic disturbance representative of high frequency combustion instabilities. The model is representative of a combustion instability experiment, dubbed BKH, operated at the DLR Institute of Space Propulsion. In this study the response to uniform acoustic pressure and transverse acoustic velocity forcing is investigated. The model results are compared with optical data from BKH experiments and are shown to reproduce the deformation of the LOx core under acoustic excitation.

description: Liquid oxidizer injection systems play an important role in hybrid rocket motors. In most configurations, a liquid oxidizer is injected in the combustion chamber by means of an atomizer, and a spray is formed. The liquid oxidizer droplets vaporize in the pre-chamber and combustion port where they react with gaseous fuel originated from the solid grain surface. The characteristics of the liquid oxidizer spray have significant effects on the solid fuel regression rate, combustion stability and, thus, the overall propulsive system performance. The aim of this research is to study the impact of the injection system design on the characteristics of the oxidizer flow pattern, and to evaluate different injectors for future testing in firing conditions using paraffin fuel and N2O oxidizer. For this purpose, three types of injector plates were designed, manufactured and tested: hollow-cone, pressure swirl and vortex. The design was driven by the requirement of an oxidizer mass flow of 550 g/s. The tests were carried out in \"cold\" conditions, first, with water, and then, with the oxidizer (nitrous oxide N2O). The discharge coefficient of each type of injector plate was obtained. The main parameters of a spray such as spray semi-angle were measured using a high-speed camera, and the Sauter Mean Diameter (SMD) and droplet size distribution - using a laser scattering system. The flow patterns of each type were compared with the base-line showerhead injector used with the same mass flow rate. Based on the results of the current experimental investigation in \"cold\" conditions, the evaluation of the three designs of a liquid oxidizer injection system was done in order to estimate the best fit for the firing tests using the 1 kN lab-scale hybrid rocket motor developed at Universite Libre de Bruxelles (ULB).

Country image effects on employer attractiveness

description: A recent trend is changing the global business environment. An increasing number of emerging markets multinationals (EMMs) based in developing countries are expanding their businesses in the developed economies. This trend has opened up new research areas because there is little or no research available on the country-level factors that affect recruitment initiatives. It is imperative for companies to accurately assess how the image of their country of origin is perceived for recruitment purposes because human resources are a source of competitive advantage. This thesis investigated this new avenue of research by drawing on the literature on marketing and management to understand country image effects on employer attractiveness to potential employees. The existing literature on recruitment has largely focused on the factors at job and organisation levels that attract jobseekers. Three new constructs – country image, jobseeker ethnocentrism and industry expertise are investigated in this thesis. The last two constructs are theorized and introduced with measurement scales for the first time by this thesis. The main research findings are that two country-level factors- country image and industry expertise-are the key predictors of employer attractiveness. Further, jobseekers in developed and developing economies show a higher preference for EMMs from countries which have industry expertise. This thesis has identified the significant effects of country-level factors on employer attractiveness. By theorizing and introducing two new constructs with measurement scales, the thesis also increases our understanding of the constituents used by jobseekers in the evaluation of local and foreign employers. The cross-national investigation provides results which have higher validity and generalizability.
Citizens of the world: the integration of transnationally connected Bangladeshi and Pakistani immigrants into Australian society

description: The purpose of this study was to research the settlement and transnational activities of Bangladeshi and Pakistani migrants who had arrived in Australia during the 1980-2002 and permanently residing in Melbourne. As a lack of information existed relative to their settlement, integration and transnational perspectives, a detailed research study was conducted through a semi-structured questionnaire survey, involving 73 Bangladeshi and 71 Pakistani respondents living in Melbourne at the time of interview. In order to address the central research question, both quantitative and qualitative techniques using multiple research methods have been used in the present research. The research question was ‘how well have the Bangladeshi and Pakistani transnationally connected migrants settled and integrated into the host Australian society in Melbourne?.

The research revealed that that respondents’ life, from the moment of arrival in a new land, was always challenging and to some of them, was not successful. They discovered a huge difference between the pre and post departure situations. In the statistical analysis, it was found that social, economic (employment and income) and psychological factors showed higher levels of correlationships with the level of social integration. The study revealed that some respondents from both communities integrated well, both socially and psychologically within a short time of arrival and for some, it was not. The level of social integration showed variations among different socio-economic categories of the Bangladeshi and Pakistani communities in Melbourne. The study has shown, to some extent, that the process of acculturation through adaptation in Melbourne by the two communities, have been a two way process where migrant respondents as well as the host society, have accepted as well as rejected each other in the process.

Respondents of both communities were found deeply engaged in transnational activities. They have also developed linear as well as circular networks od social connection across the globe. The increased involvement in transnational activities by both the permanent and temporary migrants in countries of destinations, have modified the shape and nature of traditional diaspora. However, despite high levels of transnational engagements, respondents from both communities opined that such intensive transnational engagements did not impede their normal activities and thereby the processes of integration. The dimension of diaspora is changing with time and increased interaction between diasporic and transnational migrants are becoming more visible in the community. The result of such interaction is evident in the formation of ‘trans-diasporic’ ethnic communities in Australian society and the Bangladeshi and Pakistani migrants were not an exception.
