- Description: Background: While agriculture has taken much environmental water in Australia's Murray-Darling Basin, agricultural expansion has resulted in a vast number of farm dams, almost three-quarters of a million in the Murray-Darling Basin alone. Methods: Over a summer we studied (1) waterbird abundance and species richness and (2) the influence of biophysical and landscape characteristics across 49 farm dams at a large mixed-enterprise farm in northern Victoria on the southern reach of the Murray-Darling Basin. Results: On average, dams were found to host 27.1 ± 71.1 individuals/ha and 1.8 ± 2.9 species per pond. Such densities are comparable to those on natural wetlands. Dam surface area and perimeter and amount of vegetation were positively and strongly correlated with the Rallidae density (birds/ha), but no other parameters were strongly correlated with any other functional group. The landscape in which the dams were embedded had a highly significant effect (p < 0.001) on the number of birds found on a dam. Conclusions: Our research needs to be complemented with further studies in other parts of the Basin and on other taxa, but given at our site they supported similar densities of individuals and species to natural wetlands, and given the fact that there are 710,539 farm dams in the Murray-Darling Basin, which hosts much of Australia's waterbird fauna, it is reasonable to suggest that farm dams are overlooked, and possibly very important, avian biodiversity hotspots. It also highlights the importance of a landscape setting, in which dams are situated, on the number of birds using the dams. © 2017 The Author(s).

- Description: Whilst it is agreed that climate change will impact on the long-term interactions between crops and weeds, the results of this impact are far from clear. We suggest that a thorough understanding of weed dominance and weed interactions, depending on crop and weed ecosystems and crop sequences in the ecosystem, will be the key determining factor for successful weed management. Indeed, we claim that recent changes observed throughout the world within the weed spectrum in different cropping systems which were ostensibly related to climate change, warrant a deeper examination of weed vulnerabilities before a full understanding is reached. For example, the uncontrolled establishment of weeds in crops leads to a mixed population, in terms of C3 and C4 pathways, and this poses a considerable level of complexity for weed management. There is a need to include all possible combinations of crops and weeds while studying the impact of climate change on crop-weed competitive interactions, since, from a weed management perspective, C4 weeds would flourish in the increased temperature scenario and pose serious yield penalties. This is particularly alarming as a majority of the most competitive weeds are C4 plants. Although CO2 is considered as a main contributing factor for climate change, a few Australian studies have also predicted differing responses of weed species due to shifts in rainfall patterns. Reduced water availability, due to recurrent and unforeseen droughts, would alter the competitive balance between crops and some weed species, intensifying the crop-weed competition pressure. Although it is recognized that the weed pressure associated with climate change is a significant threat to crop production, either through increased temperatures, rainfall shift, and elevated CO2 levels, the current knowledge of this effect is very sparse. A few models that have attempted to predict these interactions are discussed in this paper, since these models could play an integral role in developing future management programs for future weed threats. This review has presented a comprehensive discussion of the recent research in this area, and has identified key deficiencies which need further research in crop-weed eco-systems to formulate suitable control measures before the real impacts of climate change set in. © 2017 Ramesh, Matloob, Aslam, Florentine and Chauhan.

- Description: Purpose To identify the barriers and enablers that influence clinicians' implementation of early rehabilitation in critical care. Materials and methods Qualitative study involving 26 multidisciplinary participants who were recruited using purposive sampling. Four focus groups were conducted using semistructured questions to explore attitudes, beliefs, and experiences. Data were transcribed verbatim and thematic analysis was performed. Results Six themes emerged, as follows: (1) the clinicians' expectations and knowledge (including rationale for rehabilitation, perceived benefits, and experience), (2) the evidence for and application of rehabilitation (including beliefs regarding when to intervene), (3) patient factors (including prognosis, sedation, delirium, cooperation, motivation, goals, and family), (4) safety considerations (including physiological stability and presence of devices or lines), (5) environmental influences (staffing, resources, equipment, time, and competing priorities), and (6) culture and teamwork. Key strategies identified to facilitate rehabilitation included addressing educational needs for all multidisciplinary team members, supporting junior nursing staff, and potential expansion of physiotherapy staffing hours to closer align with the 24-hour patient care model. Conclusions Key barriers to implementation of early rehabilitation in critical care are diverse and include both clinician- and health care system–related factors. Research targeted at bridging this evidence-practice gap is required to improve provision of rehabilitation. © 2016 Elsevier Inc.

- Description: Objectives: Various definitions for concussion have been proposed, each having its strengths and weaknesses. We reviewed and compared current definitions and identified criteria necessary for an operational definition of sports-related concussion (SRC) in preparation of the 5th Concussion Consensus Conference (Berlin, Germany). We also assessed the role of biomechanical studies in informing an operational definition of SRC. Design: This is a systematic literature review. Data sources: Data sources include MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Clinical Trials and SPORT Discus (accessed 14 September 2016). Eligibility criteria for selecting studies: Eligibility criteria were studies reporting (clinical) criteria for diagnosing SRC and studies containing SRC impact data. Results: Out of 1601 articles screened, 36 studies were included (2.2%), 14 reported on criteria for SRC definitions and 22 on biomechanical aspects of concussions. Six different operational definitions focusing on clinical findings and their dynamics were identified. Biomechanical studies were obtained almost exclusively on American football players. Angular and linear head accelerations linked to clinically confirmed concussions demonstrated considerable individual variation. Summary/conclusions: SRC is a traumatic brain injury that is defined as a complex pathophysiological process affecting the brain, induced by biomechanical forces with several common features that help define its nature. Limitations identified include that the current criteria for diagnosing SRC are clinically oriented and that there is no gold/standard to assess their diagnostic properties. A future, more valid definition of SRC would better identify concussed players by demonstrating high predictive positive/negative values. Currently, the use of helmet-based systems to study the biomechanics of SRC is limited to few collision sports. New approaches need to be developed to provide objective markers for SRC. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

- Description: Knowledge about developmental theories is important for experts or specialists working with children following normal development and children who have various kinds of dysfunction, in order to better understand what happens with processes associated with motor behavior. In this article, we have explored how theories of development and learning can be used to understand processes associated with motor behavior. A probabilistic perspective emphasizes that the changes taking place in the development is a result of interaction: structural changes in the nervous system leading to changes in function and behavior and opposite, functional changes resulting in changes in structure. This bidirectional interaction between biological and experiential aspects is a continuous process which cannot be reduced to either organism or environment. Dynamical systems theory (DST) emphasizes that it is the interaction between the person, the environment, and the task that changes how our movements are, also in terms of how we develop and learn new movements. The interplay between these factors will, over time, lead to changes in motor development. The importance of experience is central to Edelman's theory of neuronal group selection (NGST). Activation of the nervous system increases the connections between certain areas of the brain, and the selection processes in the brain are a result of enhancement of neural connections involved in a "successful" motion. The central nervous system adapts its structure and function in response to internal and external influences, and hence neural plasticity is a prerequisite for learning and development. We argue that Edelman´s approach supports the theory of specificity of learning. From the perspectives of probabilistic epigenesis, DST, and NGST, we can see that being physically active and having the opportunity to get different movement experiences are of great significance for promoting motor development and learning. A variation of purposeful or rewarding physical activity in a variety of contexts will provide individual opportunities for changes of behavior in terms of both quantitative and qualitative changes in motor development.

It argues that while the protected areas framework is a potentially useful means by which to recognise the biodiversity contributions of some ICCAs, it is not universally appropriate. In this context, and subject to important caveats, OECM-related frameworks offer an important opportunity to increase recognition and support for ICCAs. The paper concludes with two practical recommendations: first for the development of supplementary guidance on OECMs and ICCAs; and second, for further discussion by a wide range of interested parties on whether 'OECMs' should be referred to as 'conserved areas'.

- Description: Objective-Sclerostin (SOST) has been identified as an important regulator of bone formation; however, it has not been previously implicated in arterial disease. The aim of this study was to assess the role of SOST in aortic aneurysm (AA) and atherosclerosis using human samples, a mouse model, and in vitro investigations. Approach and Results-SOST protein was downregulated in human and mouse AA samples compared with controls. Transgenic introduction of human SOST in apolipoprotein E-deficient (ApoE(-/-)) mice (SOSTTg. ApoE(-/-)) and administration of recombinant mouse Sost inhibited angiotensin II-induced AA and atherosclerosis. Serum concentrations of several proinflammatory cytokines were significantly reduced in SOSTTg. ApoE(-/-) mice. Compared with controls, the aortas of mice receiving recombinant mouse Sost and SOSTTg. ApoE(-/-) mice showed reduced matrix degradation, reduced elastin breaks, and preserved collagen. Decreased inflammatory cell infiltration and a reduction in the expression of wingless-type mouse mammary virus integration site/beta-catenin responsive genes, including matrix metalloproteinase-9, osteoprotegerin, and osteopontin, were observed in the aortas of SOSTTg. ApoE(-/-) mice. SOST expression was downregulated and the winglesstype mouse mammary virus integration site/beta-catenin pathway was activated in human AA samples. The cytosinephosphate- guanine islands in the SOST gene promoter showed significantly higher methylation in human AA samples compared with controls. Incubation of vascular smooth muscle cells with the demethylating agent 5-azacytidine resulted in upregulation of SOST, suggesting that SOST is epigenetically regulated. Conclusions-This study identifies that SOST is expressed in the aorta and downregulated in human AA possibly because of epigenetic silencing. Upregulating SOST inhibits AA and atherosclerosis development, with potential important implications for treating these vascular diseases.

- Description: Although Obsessive-Compulsive Disorder (OCD) and Depression are classified as separate disorders, the high incidence of co-morbidity and the strong correlations between measures of each has led to debate about the nature of their relationship. Some authors have proposed that OCD is in fact a mood disorder while others have suggested that the two disorders are grounded in negative affectivity. A third proposition is that depression is an essential part of OCD but that OCD is a separate disorder from depression. The aim in this study was to investigate these diverse propositions in a non-clinical sample and also to determine whether factors implicated in each, that is anxious and depressive cognitions, hopelessness, and self-criticism, would demonstrate commonality as predictors of the symptoms of OCD and of depression. Two hundred participants (59% female) (M age = 34 years, SD = 16) completed the Padua Inventory, Carroll Rating Scale, Cognitions Checklist, Self-Criticism Scale, Beck Hopelessness Scale, Buss-Durkee Hostility Inventory-Revised and a Negative Affectivity Schedule. Results indicated a strong correlation between OCD and depression, depression, and negative affectivity but a weaker relationship between OCD and negative affectivity. Path analyses revealed that both anxious and depressive cognitions, as well as hostility predicted both disorders but the Beta-weights were stronger on OCD. Self-criticism predicted only depression while hopelessness failed to predict either disorder but was itself predicted by depressive cognitions. Depression was a stronger indicator of negative affect than OCD and while OCD positively predicted depression, depression was a negative indicator of OCD. These results support the hypothesis that OCD and depression are discrete disorders and indicate that while depression is implicated in OCD, the reverse does not hold. While both disorders are related to negative affectivity, this relationship is much stronger for depression thus failing to confirm that both are subsumed by a common factor, in this case, negative affectivity. The proposition that depression is part of OCD but that OCD is not necessarily implicated in depression and is, in fact, a separate disorder, is supported by the current model. Further research is required to support the utility of the model in clinical samples. © 2017 Moore and Howell.

The proposition that depression is part of OCD but that OCD is not necessarily implicated in depression and is, in fact, a separate disorder, is supported by the current model. Further research is required to support the utility of the model in clinical samples. © 2017 Moore and Howell.
Your stories, my stories, our stories : Power/knowledge relations and Koorie perspectives in discourses of Australian History Education

- Description: Over the past decade, popularised notions and approaches to the teaching and learning of Australia’s history have been overwhelmingly researched and written by non-Indigenous academics. This research challenges dominant non-Indigenous curriculum and research agendas by exploring how, why, and to what degree Koorie, and by extension Aboriginal and Torres Strait Islander perspectives, are taken up for the development and implementation of school-based curriculum aligned to the Year Nine Australian Curriculum: History. The research is guided by Michel Foucault’s poststructural theory to examine a range of discourses identified by year nine history teachers and three Koorie Elders in Ballarat and Greater Shepparton. It is supplemented through Martin Nakata’s ground breaking work on Indigenous Standpoint Theory to acknowledge and highlight the cross-cultural/racial power/knowledge relations of peoples who are involved in the research. It is a timely response to the 2013 mandatory implementation of the Australian Curriculum: History in Victorian state schools. The research builds upon academic research (see Clark, 2006; Harrison & Greenfield, 2011; Mackinlay & Barney, 2011; 2014b) about how teachers may engage critically with Aboriginal and Torres Strait Islander specific content. It contributes significantly to a field of research that has not received much attention over the past eleven years. The research is a striking contribution to understandings of Australian cross-cultural/racial research and education practices. It argues that teachers are not necessarily insensitive to cross-cultural/racial relations operating in Australia; rather, that more rigorous and comprehensive teacher education programs are required for the integration of Koorie perspectives on Australian history. The research clearly demonstrates that stories from local Koorie communities offers up a wealth of knowledge that may be drawn upon to reform curriculum agendas towards shared-history understandings of Australia’s history. Ultimately, it advocates for a more nuanced and mature conversation about contemporary cross-cultural/racial education practices in Australia.

Unscrupulous operators have identified its potential and started to use this platform for identity theft in form of so called Online Romance Scams. Quickly, this cybercrime has become very successful and thus, an increasing threat in the social networking environment. So far, very little is known about its structure and the reason for its success, and this needs to be known in order to be able to fight it efficiently. This research tries to contribute to this knowledge, and argues that scammers use so-called ‘Love Stories’, which represent personal affinities related to romantic relationships, to their benefit when tailoring common narratives as part of fraudulent online profiles to attract their victims. We look at these different types of ‘Personal Love Stories’ and discuss how they can be used in this type of scam, followed by a qualitative analysis of fraudulent profiles from three different international websites to examine this assumption

- Description: Participating in physical activity is important for maintaining general health. When physiotherapists promote physical activity for the purposes of maintaining or improving a patient’s general health, they are promoting non-treatment physical activity. Physiotherapists have a responsibility to promote non-treatment physical activity to their patients while also providing the patient with treatment for their presenting complaint. This qualitative study explored the experiences of Australian physiotherapists promoting non-treatment physical activity to patients with musculoskeletal conditions. Ten Australian physiotherapists treating patients with musculoskeletal conditions in private practice and outpatient settings were recruited using a social media campaign and snowballing. All interviewees received one $AU20 gift card for participating. Sixty-minute semi-structured interviews were conducted and were transcribed verbatim. Interpretative phenomenological analysis was used to design the interview guide and analyse data. Transcripts were used to identify emergent and superordinate themes. Most interviewees were female, aged between 25–34 years, physically active and reported promoting NTPA. The superordinate themes that emerged from the transcripts included: Internal and external influences on NTPA promotion, approach taken by the physiotherapist towards NTPA promotion, challenges experienced when promoting NTPA, and skills and training. In conclusion, physiotherapists reported they were well-placed to promote NTPA, but they face many challenges. The perceived inability to motivate patients to become physically active and the need to prioritise patient expectations of hands-on therapy made NTPA promotion difficult. Workplace specific factors, such as having an open-plan clinic environment and having other staff who promote NTPA, were perceived to make NTPA promotion easier. Using effective marketing strategies that portray the physiotherapy clinic as a physically active environment might see patients expect NTPA promotion, making NTPA promotion easier for Australian physiotherapists in the future.

"Beyond home and sex?" : Gender and sexuality in Elizabeth Moon's
- Authors: O'Sullivan, Jennifer
- Date: 2018
- Type: Text , Thesis , Masters
- Full Text:
- Description: Historically, fantasy fiction has tended to present sexuality and gender in a conservative light. Contemporary authors in this genre have the opportunity to imagine worlds in which they can critique these norms and offer new and subversive alternatives. Elizabeth Moon’s work has been seen by some readers and critics (Mains, et al, Bach) to challenge conservative gender roles, and while in some areas this is evident, a critical reading of her Paksworld series through a feminist lens reveals that her work is still largely restricted by normative notions of gender and heteronormative contexts and ideals. In this thesis I argue that while Moon’s female characters are allowed a certain amount of autonomy, they are still often repressed by those around them, silenced, or subject to male dominance and/or sexual violence. Those women in the novels who achieve a position of social, political or spiritual power are forced to make choices between roles: for example, between being a warrior and a mother, and are not allowed to ‘have it all’. Moon does subvert some familiar feminine tropes – her fantasy princesses for example avoid being married against their will, and her female warriors are more complex than simply being ‘sheroes’. Utilising masculinities and disability theory, I also analyse Moon’s treatment of men and masculinity. While Moon presents several familiar male fantasy tropes, she also portrays some surprisingly subversive men. These men are forced to reimagine and reinterpret their own masculine identities by having to confront ageing, disability, mutilation and loss of personal power while negotiating traditionally masculine homo-social environments. Finally, I argue that Moon’s presentation of sexuality in the Paksworld series is problematic and conservative in that very few of her characters are having pleasurable, consensual sex, especially not outside traditional marriage structures. Furthermore, the Paksworld series is largely heteronormative, with same-sex desire identified predominantly with a character who is presented as an antagonist to Paks. Paks herself is asexual, and I argue that Moon uses this as a way to avoid dealing with the issue of female sexual desire rather than an opportunity to explore asexuality as a valid sexual preference or identity. Overall, I argue that despite some subversive elements, Moon’s characters are still largely restricted by conservative expectations of genre, culture, gender and sexuality.

- Description: As with other industrialized nations Australia's population is aging and older workers are encouraged to work for longer. At the same time, Australia's university sector, which is aging, is being reconfigured through changes that potentially marginalize its older workers as higher education institutions try to become more competitive in a global market. In this context, youthfulness appears to embody competitiveness and academic institutions are increasingly aspiring to a young workforce profile. This qualitative article builds on previous research to explore to what extent ageist assumptions shape attitudes to older workers and human resource management (HRM) practices within Australian universities even when HRM practitioners are well versed in antidiscrimination legislation that (unlike the Age Discrimination in Employment Act in the United States) applies to workers of all ages. Semistructured interviews conducted with 22 HRM practitioners in Australian universities reveal that university HRM practices generally overlook the value of retaining an older workforce by conflating "potential" with "youthfulness," assuming that staff potential and performance share a negative correlation with age. While mostly lower-ranked institutions have attempted to retain older academics to maintain an adequate labor supply, this study finds that university policies targeting the ongoing utilization of older workers generally are underdeveloped. Consequently, the availability of late career employment arrangements is dependent upon institutions' strategic goals, with favorable ad hoc solutions offered to academics with outstanding performance records, while a rhetoric of performance decline threatens to marginalize older academic researchers and teachers more generally.

100 years of annual reporting by Australian Red Cross : Accountability amidst wars, disasters and loss of life
- Authors: Langton, Jonathan
- Date: 2018
- Type: Text , Thesis , PhD
- Full Text:
- Description: Purpose: This critical interpretive and historical case study of Australian Red Cross extends from the organisation’s beginning in 1914 through to the present day. The overarching purpose is to reveal and analyse the annual reporting practices of one of Australia’s oldest and most important humanitarian organisations in the discharge of accountability over the course of a century. Design/methodology/approach: A Political Economy of Accounting theoretical framework guides the content analysis and interpretation of findings. Background: While the review of literature acknowledges the annual report as a crucial element in the discharge of accountability, studies investigating the evolution of annual reports of International nongovernmental development and humanitarian aid organisations (INGDHOs) over extended periods of time appear to be absent from the literature. Findings: The annual reports were found to be responsive to the changing social, political, economic and institutional environment, casting doubt on any claims to objectivity in organisational management’s disclosures, including assertions regarding unadulterated adherence to its Fundamental Principles. Furthermore, sources of pressure from the wider environmental context impacted upon the development of accountability regimes and shaped the way in which organisational management reported to stakeholders. These regimes evidence the alignment of mission preservation and emotive disclosures with strategic priorities. Implications: This study extends understandings of how INGDHOs discharge accountability through annual reporting practices. It provides a more holistic framework for understanding the role of accountability in organisational management reporting, the development of accountability regimes and the implications for organisational and social functioning. Originality/value (significance): The contribution is distinctive not only for the context and extensive period covered, but also for the significant institutional setting of Australian Red Cross – encompassing deep social, political, economic and institutional changes. This adds to the extant literature and provides significant insights into the contested interplay between annual reporting practices and accountability regimes.

- Description: The primary aims were to determine the 12-month incidence (and comorbidity) of symptoms of common mental disorders (CMD) among male professional rugby players and to explore their association with potential stressors. A secondary aim was to explore the view of male professional rugby players about the consequences of symptoms of CMD and related medical support/needs. An observational prospective cohort study with three measurements over a 12-month period was conducted among male professional rugby players from several countries. Symptoms of CMD (distress, anxiety/depression, sleep disturbance, eating disorders and adverse alcohol use) and stressors (adverse life events, rugby career dissatisfaction) were assessed through validated questionnaires. A total of 595 players (mean age of 26 years; mean career duration of 6 years) were enrolled, of which 333 completed the follow-up period. The incidence of symptoms of CMD were: 11% for distress, 28% for anxiety/depression, 12% for sleep disturbance, 11% for eating disorders and 22% for adverse alcohol use (13% for two simultaneous symptoms of CMD). Professional rugby players reporting recent adverse life events or career dissatisfaction were more likely to report symptoms of CMD but statistically significant associations were not found. Around 95% of the participants stated that symptoms of CMD can negatively influence rugby performances, while 46% mentioned that specific support measures for players were not available in professional rugby. Supportive and preventive measures directed towards symptoms of CMD should be developed to improve not only awareness and psychological resilience of rugby players but also their rugby performance and quality-of-life. © 2018, © 2018 The Author(s).

A comparative analysis of domestic violence against women in Australia and Bangladesh : government policies, legislation and organisational responses

- Description: This is a comparative study of Domestic Violence (DV) between Australia (Victoria) and Bangladesh. It examined the interrelationship between factors which contribute to DV, government policies and legislation developed to deal with DV, and organisational responders (police and DV Crisis Support Services) implementing strategies and remedies in the policies and legislation. A comparative country case study strategy was adopted utilising triangulation of methods of data collection including an analysis of the countries’ respective policies and legislation and conducting in-depth interviews with key responder personnel. The conceptual framework identified policies and legislation as Steering Media, which influenced a society’s beliefs embedded in the Lifeworld, and which guided the actions of responders to DV in the two different countries’ Systems. Differences and similarities were found between the two countries. The main common factor was the identification of gender inequality as an underlying factor causing DV. Some social and cultural factors exist in both countries such as poverty. Some factors were specific to Australia, such as the consumption of alcohol; and in Bangladesh, such as dowry and dependency on men. Of significance is that gender equality is enshrined in the Bangladeshi Constitution, while Australia relies on legislation that could potentially be changed to disadvantage women. Differences revealed include identification of victims and perpetrators, with Bangladesh specifically naming women and children as victims but never the perpetrator and Australia (Victoria) naming any family member as victim or perpetrator. Also, responders deal with DV victims and perpetrators differently according to the policies and legislation of both countries. This research has implications for both theory and practice in both countries. The findings have potential to contribute to changes in policy and legislation related to DV as well as in the practice level by responders across both countries, learning from each other in the process.

A computer-aided sustainable modelling and optimization analysis of cnc milling and turning processes

- Description: The sustainability of a manufacturing process can be measured by three main factors which impact both ecological and financial constraints. These factors are the energy required to achieve a specific job, the material utilized for the job, and the time taken to complete that job. These factors have to be quantified and analysed so that a proper manufacturing system can be designed to optimize process sustainability. For this purpose, a computer package, which utilizes life cycle inventory models has been presented for CNC (Computer Numerical Control) milling and turning processes. Based on utilization of resources and production stages, the job completion time for the turning and milling processes can be divided into process (i.e., machining), idle and basic times. As parameters are different for evaluating the process times, i.e., depth and width of cut in case of milling, initial and final diameters for turning, two different case studies are presented, one for each process. The effect of material selection on the sustainability factors has been studied for different processes. Our simulations show that highly dense and hard materials take more time in finishing the job due to low cutting speed and feed rates as compared to soft materials. In addition, face milling takes longer and consumes more power as compared to peripheral milling due to more retraction time caused by over travel distance and lower vertical transverse speeds than the horizontal transverse speed used in a peripheral retraction process. © 2018 by the authors.

- Description: This study contributes to the understanding of liquidity in two ways. First, it considers the multifaceted nature of liquidity and its relationship with money. Second, it constructs a conceptual framework for a theory of liquidity. The first contribution is achieved by clarifying and categorising the various forms of liquidity to identify those overlooked by the existing literature. The second contribution consists of a realist critique of the literature on liquidity and money to highlight the strengths and weaknesses of each theoretical approach. The study reflects on the attempts to analyse liquidity using moneyless models of perfect barter with the assumption that every commodity exhibits perfect saleability; an assumption that removes any need for a medium of exchange and, moreover, crowds out all other forms of liquidity. It is concluded that, because liquidity is a social and monetary phenomenon, it cannot be analysed with models populated by a representative agent consuming a single commodity. Furthermore, this conclusion is not altered by the introduction of ‘financial frictions’, which are fundamentally at odds with the nature of money. Instead, the clarification of the nature of liquidity forms the basis for an interpretation of Keynes’s theory of liquidity preference that emphasises its reliance on liquidity in general, not money in particular. The study introduces the terms redemption liquidity and exchange liquidity to explain the trade-off that underpins the theory of liquidity preference. Properly interpreted, the theory of liquidity preference can then address many of the deficiencies prevalent in the dominant theories of the rate of interest. The study therefore has implications for monetary policy and asset pricing.

- Description: Mobility management has been a long-standing issue in mobile wireless sensor networks and especially in the context of cyber physical systems its implications are immense. This paper presents a critical analysis of the current approaches to mobility management by evaluating them against a set of criteria which are essentially inherent characteristics of such systems on which these approaches are expected to provide acceptable performance. We summarize these characteristics by using a quadruple set of metrics. Additionally, using this set we classify the various approaches to mobility management that are discussed in this paper. Finally, the paper concludes by reviewing the main findings and providing suggestions that will be helpful to guide future research efforts in the area. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Muhammad Imran” is provided in this record**
