Low PAPR Square STBCs from Complex Partial-Orthogonal Designs (CPODs)

Space-time codes from complex orthogonal designs (CODs) with no zero entries offer low Peak to Average Power Ratio (PAPR) and avoid the problem of switching off antennas. But square CODs for 2(a) antennas with a + 1. complex variables, with no zero entries were discovered only for a <= 3 and if a + 1 = 2(k), for k >= 4. In this paper, a method of obtaining no zero entry (NZE) square designs, called Complex Partial-Orthogonal Designs (CPODs), for 2(a+1) antennas whenever a certain type of NZE code exists for 2(a) antennas is presented. Then, starting from a so constructed NZE CPOD for n = 2(a+1) antennas, a construction procedure is given to obtain NZE CPODs for 2n antennas, successively. Compared to the CODs, CPODs have slightly more ML decoding complexity for rectangular QAM constellations and the same ML decoding complexity for other complex constellations. Using the recently constructed NZE CODs for 8 antennas our method leads to NZE CPODs for 16 antennas. The class of CPODs do not offer full-diversity for all complex constellations. For the NZE CPODs presented in the paper, conditions on the signal sets which will guarantee full-diversity are identified. Simulation results show that bit error performance of our codes is same as that of the CODs under average power constraint and superior to CODs under peak power constraint.

Podiatry scope of practice: The role of gender in identification as a specialist

Background Ensuring efficient and effective delivery of health care to an aging population has been a major driver for a review of the health workforce in Australia. As part of this review a new National Registration and Accreditation Scheme (NRAS) has evolved with one goal being to improve workforce flexibility. With increased flexibility there have been discussions about the role specialist scopes of practice plays. This study explored the role of gender and other work related characteristics in relation to contemporary scope of podiatry practice and specialisation in Australia. Methods A cross sectional survey was administered through an on-line survey tool on behalf of the Australasian Podiatry Council. Descriptive data was collected over a three-week period. Queensland University of Technology Human Research Ethics approval was sought and confirmed exemption from review, exemption number 1400000791. Results Of the podiatrists participating in this survey (n=218), they were predominately female (66%), early career (34%, 0-9 years) and work in private practices (78%) in multi-podiatrists centres (41%). Relationship between clinical activities performed and “self-perception” of performing a “specialist role” was significant for practitioners who undertook treatment of specific patient groups. The largest area of interest was biomechanics (n=65), followed closely by diabetes (n=61), a third area identified was paediatrics (n=26). Self-perception of specialist status was compared with gender, years of experience, location, primary work environment and clinical practice. When practitioners are asked to categorise themselves to be either “generalist” or “specialist/ generalist with a special interest” podiatrist, male gender was identified as being the only factor which would predict perception of status; 64% males identified as specialist, as opposed to 49% of female survey respondents (Chi square, df = 1, P = 0.044). Self-perception of specialist status was not explained by years of experience, location, working in rural versus urban environment, state worked in, or part-time/full-time work status. Conclusions In conclusion; gender, work environment plus area of interest form a complex relationship, which appear to influence both perception and reality of service provision. Incorporation of specialisation activity (surgical podiatry along with endorsement for use of scheduled medicines) will have lasting impact on the scope of the podiatry profession in Australia. To meet community expectation and maintain high standards, the addition of new subspecialties may be indicated.

Genetic association analysis of miRNA SNPs implicates MIR145 in breast cancer susceptibility

Background MicroRNAs (miRNAs) are important small non-coding RNA molecules that regulate gene expression in cellular processes related to the pathogenesis of cancer. Genetic variation in miRNA genes could impact their synthesis and cellular effects and single nucleotide polymorphisms (SNPs) are one example of genetic variants studied in relation to breast cancer. Studies aimed at identifying miRNA SNPs (miR-SNPs) associated with breast malignancies could lead towards further understanding of the disease and to develop clinical applications for early diagnosis and treatment. Methods We genotyped a panel of 24 miR-SNPs using multiplex PCR and chip-based matrix assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) analysis in two Caucasian breast cancer case control populations (Primary population: 173 cases and 187 controls and secondary population: 679 cases and 301 controls). Association to breast cancer susceptibility was determined using chi-square (X 2 ) and odds ratio (OR) analysis. Results Statistical analysis showed six miR-SNPs to be non-polymorphic and twelve of our selected miR-SNPs to have no association with breast cancer risk. However, we were able to show association between rs353291 (located in MIR145) and the risk of developing breast cancer in two independent case control cohorts (p = 0.041 and p = 0.023). Conclusions Our study is the first to report an association between a miR-SNP in MIR145 and breast cancer risk in individuals of Caucasian background. This finding requires further validation through genotyping of larger cohorts or in individuals of different ethnicities to determine the potential significance of this finding as well as studies aimed to determine functional significance.

Meillä ei ole ikuisia ystäviä eikä ikuisia vihollisia. Ikuisia ovat meidän omat etumme. : Suomen suhteet Kiinan kansantasavaltaan 1949 - 1989

"We have neither Eternal Friends nor Eternal Enemies. We have only Eternal Interests .Finland's Relations with China 1949-1989 The study focuses on the relations between Finland and the People s Republic of China from 1949-1989 and examines how a small country became embroiled in international politics, and how, at the same time, international politics affected Finnish-Chinese relations and Finland s China policy formulation. The study can be divided into three sections: relations during the early years, 1949-1960, before the Chinese and Soviet rift became public; the relations during the passive period during the 1960s and 1970s; and the impact of China s Open Door policy on Finland s China policy from 1978-1989. The diplomatically challenging events around Tiananmen Square and the reactions which followed in Finland bring the study to a close. Finland was among the first Western countries to recognise the People s Republic and to establish diplomatic relations with her, thereby giving Finland an excellent position from which to further develop good relations. Finland was also the first Western country to sign a trade agreement with China. These two factors meant that Finland was able to enjoy a special status with China during the 1950s. The special status was further strengthened by the systematic support of the government of Finland for China's UN membership. The solid reputation earned in the 1950s had to carry Finland all the way through to the 1980s. For the two decades in between, during the passive policy period of the 1960s and 1970s, relations between Finland and the Soviet Union also determined the state of foreign relations with China. Interestingly, however, it appeared that President Urho Kekkonen was encouraged by Ambassador Joel Toivola to envisage a more proactive policy towards China, but the Cultural Revolution cut short any such plan for nearly twenty years. Because of the Soviet Union, Finland held on to her passive China policy, even though no such message was ever received from the Soviet Union. In fact, closer relationships between Finland and China were encouraged through diplomatic channels. It was not until the presidency of Mauno Koivisto that the first high-level ministerial visit was made to China when, in 1984, Foreign Minister Paavo Väyrynen visited the People s Republic. Finnish-Chinese relations were lifted to a new level. Foreign Minister Väyrynen, however, was forced to remove the prejudices of the Chinese. In 1985, when the Speaker of the Finnish Parliament, Erkki Pystynen visited China he also discovered that Finland s passive China policy had caused misunderstandings amongst the Chinese politicians. The number of exchanges escalated in the wake of the ground-breaking visit by Foreign Minister Väyrynen: Prime Minister Kalevi Sorsa visited China in 1986 and President Koivisto did so in 1988. President Koivisto stuck to practical, China-friendly policies: his correspondence with Li Peng, the attitude taken by the Finnish government after the Tiananmen Square events and the subsequent choices made by his administration all pointed to a new era in relations with China.

Public Open Spaces in Kathmandu Valley: A Review of Contemporary Problems and Historic Precedents

The current growth of Kathmandu Valley has been malignant in many ways which suggests a decline of public realm in the city. As the current efforts for planning and design of public open space exhibit numerous problems related to both physical and social aspects of city building, this book examines the shortcomings with contemporary urban development from urban planning and design point of view and attempts to suggest methods to overcome such shortcomings based on the study of historic urban squares. This book identifies the inherent urban design qualities of the historic urban squares in order to learn from them and also attempts to put forward the principles and guidelines for contemporary public space design based on such findings.

Promoting articulated action from diverse stakeholders in response to public policy scenarios: A case analysis of the use of ‘scenario improvisation’ method

In this paper we present a novel application of scenario methods to engage a diverse constituency of senior stakeholders, with limited time availability, in debate to inform planning and policy development. Our case study project explores post-carbon futures for the Latrobe Valley region of the Australian state of Victoria. Our approach involved initial deductive development of two ‘extreme scenarios’ by a multi-disciplinary research team, based upon an extensive research programme. Over four workshops with the stakeholder constituency, these initial scenarios were discussed, challenged, refined and expanded through an inductive process, whereby participants took ‘ownership’ of a final set of three scenarios. These were both comfortable and challenging to them. The outcomes of this process subsequently informed public policy development for the region. Whilst this process did not follow a single extant structured, multi-stage scenario approach, neither was it devoid of form. Here, we seek to theorise and codify elements of our process – which we term ‘scenario improvisation’ – such that others may adopt it.

Lower-bound collapse load Of square footing

Based on a radial moment field and the square yield criterion, a lower-bound collapse load is developed for a square footing subjected to a generalized contact pressure distribution. The current lower-bound collapse load compares well with the available upper-bound solutions.

Private governance of public rights in Japan: Revisiting the Japanese governance debate

Dramatic growth in the Japanese economy in the postwar period – and its meltdown in the 1990s – has attracted sustained interest in the power dynamics underlying the management of Japan’s administrative state. For a long time, scholars and commentators have debated about who wields power in Japan. The question has been asked in different ways. In the 1970s and 1980s, the question was usually posed as: who orchestrated Japan’s economic miracle in the 1960s and 1970s? Today, the question is usually reframed to: who is accountable for the policy failures that plunged Japan into financial crisis and recession during the 1990s? Yet the core issue remains the same – who governs Japan? (Johnson 1995)...

Models for engaging public-private partnerships in civil infrastructure projects: A case of ‘having your cake and eating it too’?

Public-Private Partnerships (PPP) are established globally as an important mode of procurement and the features of PPP, not least of which the transfer of risk, appeal to governments and particularly in the current economic climate. There are many other advantages of PPP that are claimed as outweighing the costs of PPP and affording Value for Money (VfM) relative to traditionally financed projects or non-PPP. That said, it is the case that we lack comparative whole-life empirical studies of VfM in PPP and non-PPP. Whilst we await this kind of study, the pace and trajectory of PPP seem set to continue and so in the meantime, the virtues of seeking to improve PPP appear incontrovertible. The decision about which projects, or parts of projects, to offer to the market as a PPP and the decision concerning the allocation or sharing risks as part of engagement of the PPP consortium are among the most fundamental decisions that determine whether PPP deliver VfM. The focus in the paper is on latter decision concerning governments’ attitudes towards risk and more specifically, the effect of this decision on the nature of the emergent PPP consortium, or PPP model, including its economic behavior and outcomes. This paper presents an exploration into the extent to which the seemingly incompatible alternatives of risk allocation and risk sharing, represented by the orthodox/conventional PPP model and the heterodox/alliance PPP model respectively, can be reconciled along with suggestions for new research directions to inform this reconciliation. In so doing, an important step is taken towards charting a path by which governments can harness the relative strengths of both kinds of PPP model.

Public-private partnerships in information and communication technology for education

Public-private partnerships (PPPs) have generated a lot of interest from governments around the world for leveraging private sector involvement in developing and sustaining public infrastructure and services. Initially, PPPs were favoured by transport, energy, and other large infrastructure-intensive sectors. More recently, the concept has been expanded to include social sectors such as education.

Public trust in Australian charities: Accounting for cause and effect

This paper reports on a study of the key determinants of public trust in charitable organisations, using survey data commissioned by the Australian Charities and Not-for-profits Commission. Data analysis used partial least squares structural equation modelling to examine both antecedents of trust and the influence of trust on charitable donative intentions. We found that people tend to trust charities with which they are familiar, and which are transparent in their reporting. Organisational size, importance, reputation and national significant were also antecedents of trust. People are more likely to volunteer or donate to charities they trust. The practical implications of this are that charities seeking to enhance their volunteer and donation base should pay attention to their marketing, reputation and disclosure activities, as well as to doing good work on an ongoing basis in the community. Theoretically, the implications are that transparency and reputation do not result directly in donations and volunteering, but they do create trust, and it is trust which then leads to donations and volunteering.

Union-Management Training Programs in the Public Sector: The New York Experience

[Excerpt] New York State has a long history of union-management education and training programs, making it unique in public sector employment. This chapter examines the programs undertaken at both state and city levels, as well as the applicability of the New York experience to other public sector jurisdictions. Although the profile of the New York State and city work force differs from that of the rest of the nation, there is much of value here for educators, union leaders, and others involved in public sector employment.

Bearing capacity of square footings on geosynthetic reinforced sand

The results from laboratory model tests and numerical simulations on square footings resting on sand are presented. Bearing capacity of footings on geosynthetic reinforced sand is evaluated and the effect of various reinforcement parameters like the type and tensile strength of geosynthetic material, amount of reinforcement, layout and configuration of geosynthetic layers below the footing on the bearing capacity improvement of the footings is studied through systemati model studies. A steel tank of size 900 x 900 x 600 mm is used for conducting model tests. Four types of grids, namely strong biaxial geogrid, weak biaxial geogrid, uniaxial geogrid and a geonet, each with different tensile strength, are used in the tests. Geosynthetic reinforcement is provided in the form of planar layers, varying the depth of reinforced zone below the footing, number of geosynthetic layers within the reinforced zone and the width of geosynthetic layers in different tests. Influence of all these parameters on the bearing capacity improvement of square footing and its settlement is studied by comparing with the test on unreinforced sand. Results show that the effective depth of reinforcement is twice the width of the footing and optimum spacing of geosynthetic layers is half the width of the footing. It is observed that the layout and configuration of reinforcement play a vital role in bearing capacity improvement rather than the tensile strength of the geosynthetic material. Experimental observations are supported by the findings from numerical analyses.

Development of an EMR implementation framework for public hospitals in Saudi Arabia

An Electronic Medical Record (EMR) is a system that has been embraced by healthcare providers worldwide. However, the implementation success of EMRs has varied widely. Studies have identified both barriers to and facilitators for implementing EMRs within healthcare organisations. In Saudi Arabia (SA), the majority of healthcare providers manage patient records manually. As public hospitals are a major provider of health services in SA and have been shown to face more EMR implementation barriers than private hospitals, there is a need for an implementation framework to guide EMR implementation in Saudi public hospitals. This doctoral project therefore aimed to develop an evidence-based EMR implementation framework for public hospitals in SA informed by those who work at the micro-implementation level and the macro-implementation level and the extant literature sensitive to the cultural, resource-related, and technological, organisational, and environmental issues of SA.

Dispelling Myths about Doctorates in the Australian Public Service

Many doctoral candidates pursue their studies with the goal of ultimately securing an academic position in a university. There are, however, many other career options for doctoral graduates in non-academic positions, including a career in the public service, either at the state or national level. Public service managers are interested in people who can demonstrate a range of skills and capacities, and most doctoral graduates will have developed a range of these skills.
