(Failed) voluntary euthanasia law reform in Australia: Two decades of trends, models and politics

Within Australia, there have been many attempts to pass voluntary euthanasia (VE) or physician-assisted suicide (PAS) legislation. From 16 June 1993 until the date of writing, 51 Bills have been introduced into Australian parliaments dealing with legalising VE or PAS. Despite these numerous attempts, the only successful Bill was the Rights of the Terminally Ill Act 1995 (NT), which was enacted in the Northern Territory, but a short time later overturned by the controversial Euthanasia Laws Act 1997 (Cth). Yet, in stark contrast to the significant political opposition, for decades Australian public opinion has overwhelmingly supported law reform legalising VE or PAS. While there is ongoing debate in Australia, both through public discourse and scholarly publications, about the merits and dangers of reform in this field, there has been remarkably little analysis of the numerous legislative attempts to reform the law, and the context in which those reform attempts occurred. The aim of this article is to better understand the reform landscape in Australia over the past two decades. The information provided in this article will better equip Australians, both politicians and the general public, to have a more nuanced understanding of the political context in which the euthanasia debate has been and is occurring. It will also facilitate a more informed debate in the future.

What if tax reform was a fundamental human right?

As an election looms in Australia, the tax debate continues unabated. Self-interest abounds. When we remove self-interest, we are often reduced to standard design principles for a taxation system. Lost in this discussion is the fundamental purpose of tax, which is to finance government expenditure. Most would argue that tax revenue should be sufficient to meet basic economic and social needs of the community. But how does a community determine what these basic economic and social needs should be? One way is by using a human rights framework. This can provide guidance for both developing and developed countries considering tax reform.

Child sexual abuse and access to justice for civil claims: Time to reform the Limitation of Actions Act 1974 (Qld)

In 2015, Victoria passed laws removing the time limit in which a survivor of child sexual abuse can commence a civil claim for personal injury. The law applies also to physical abuse, and to psychological injury arising from those forms of abuse. In 2016, New South Wales made almost identical legal reforms. These reforms were partly motivated by the recommendations of inquiries into institutional child abuse. Of particular relevance is that the Australian Royal Commission Into Institutional Responses to Child Sexual Abuse recommended in 2015 that all States and Territories remove their time limits for civil claims. This presentation explores the problems with standard time limits when applied to child sexual abuse cases (whether occurring within or beyond institutions), the scientific, ethical and legal justifications for lifting the time limits, and solutions for future law reform.

Homeowners' Associations in Russia after the 2005 Housing Reform

The thesis examines homeowners associations as a part of the large-scale housing reform, implemented in Russia since 2005. The reform transferred housing management from the public sector to the private sector and to the citizens responsibility. The reform is a continuation to the privatisation of the housing stock that was started in Russia in the beginning of the 1990s, aiming to build a market-oriented housing sector in the country. The reform makes a fundamental change to the Soviet system, in which ownership along with management and maintenance of housing were monopolised by the state. Homeowners are now responsible for the management of the common areas in privatised houses, which is often realised by establishing a homeowners association. Homeowners associations are examined by using the so-called common-pool resource regime approach, with the main question being the ways in which taking care of common property collectively succeeds in practice. The study is based on interview data of St. Petersburg s homeowners associations. Using the common-pool resource theory the study demonstrates why implementation of the housing reform has not succeeded as expected. Certain elements that characterise a successful common-pool resource regime do not fulfill sufficiently in St. Petersburg s homeowners associations. Firstly, free-riding, that is, withdrawal from the association s joint decision-making and not making the housing payments is common, as effective sanctions to prevent it are missing in the legislation. That is, eviction or expelling a non-paying member from the association is not possible. Secondly, ownership of the land plot and common areas of the house, such as basements and attics, are often disputed between the associations and authorities. In the Soviet era, these common areas were public property along with the apartments, but in privatised houses they should, according to the legislation, belong to the associations property. Thirdly, solution of disputes between the associations and authorities and within the associations is difficult, as the court system tends to be bureaucratic and inefficient. In addition to the common-pool resource approach, the study also examines how social capital contributes to the associations effectiveness and democratic governance. The study finds that although homeowners associations have increased cooperation and tightened social relations between neighbours, social capital has not been able to prevent free-riding. The study shows that unlike it is often claimed, the so-called Soviet mentality , that is, residents passiveness and unwillingness to participate, is not the most important obstacle to the reform. Instead, the reform is impeded most of all by imperfect institutional arrangements and local authorities that prevent the associations from working as independent, self-governing associations.

Resistance responses blocking systemic movement of Potato virus A in potato

Peruna kestää A-virusta estämällä sen leviämistä Peruna on maissin ohella maailman kolmanneksi tärkein ravintokasvi vehnän ja riisin jälkeen. Perunaa lisätään kasvullisesti mukuloita istuttamalla, jolloin virukset siirtyvät sairaiden siemenmukuloiden välityksellä kasvukaudesta toiseen. Virustauteja voi torjua ainoastaan terveen siemenperunan ja kestävien lajikkeiden avulla. Kestävyys perustuu usein siihen, että kasvi estää viruksen leviämisen tartuntakohdasta välttyäkseen virustaudilta. Tässä työssä tutkittiin kolmea perunan A-viruksen (PVA) liikkumista estävää kestävyysmekanismia perunassa. Lisäksi työn kokeelliseen osaan oleellisesti kuuluvaa virustartutusta varten kehitettiin uusi paranneltu versio geenipyssystä. Tämä itse rakennettu laite optimoitiin PVA:n tartuttamiseen mahdollisimman helposti ja pienin käyttökustannuksin. Tutkimuksen kohteena olleessa perunan risteytysjälkeläistössä oli PVA:ta kestäviä kasveja (ryhmä nnr), jotka estivät viruksen liikkumisen aiheuttamatta oireita tartutuskohdassa, sekä kasveja, joissa PVA aiheutti kuolioläikkinä näkyvän yliherkkyysvasteen (ryhmä HR). Molemmissa kestävyystyypeissä virus pystyi monistumaan ja leviämään solusta soluun paikallisesti, mutta liikkuminen muihin kasvinosiin nilan kautta estyi. Ryhmän nnr kasveissa PVA-tartunta ei aiheuttanut tilastollisesti merkitsevää muutosta useimpien geenien ilmenemiseen tartuntakohdassa. Ainoastaan geeniperhe, joka ilmentää tiettyä proteinaasi-inhibiittoria (PI), reagoi PVA:han 24 tuntia tartutuksesta. Kun tämän PVA:han reagoivan geeniperheen jäsenet hiljennettiin nnr- perunalinjoissa, ne muuttuivat alttiiksi PVA:lle ja virus levisi tartuntakohdasta muihin kasvinosiin. Tulos osoittaa, että PI on viruskestävyystekijä. Lisäksi muut tutkimuksessa saadut tulokset tukevat mahdollisuutta, että PI estää PVA:n P1-proteinaasin toimintaa. HR-linjoissa todettiin erilaisiin puolustusvasteisiin liittyvien PR-geenien aktivoitumista PVA-tartunnan seurauksena, mutta myös ilman sitä kasvien kasvettua mullassa noin neljä viikkoa. Sen sijaan solukkoviljelyssä tai vasta kaksi viikkoa mullassa kasvaneissa kasveissa vastaavaa ei vielä todettu. Tulos viittaa siihen, että HR-perunat reagoivat herkemmin ympäristöön ja/tai kasvin kehitysasteeseen laukaisten puolustusvasteita, jotka saattavat parantaa kestävyyttä taudinaiheuttajia vastaan. Kolmas tutkittu kestävyystyyppi havaittiin Pito-perunalajikkeessa. Se muistutti nnr-kestävyyttä siten, että myös siinä viruksen liikkuminen nilassa muihin kasvinosiin estyi. PVA:n todettiin pysähtyvän vasta lehtiruodin tyvelle muodostuvaan irtoamisvyöhykkeeseen, mitä havainnollistettiin käyttämällä muunnettua PVA-rotua, joka tuotti UV-valossa fluoresoivaa vihreää valoa. Tulos viittaa siihen, että virus ei pääse kulkemaan vyöhykkeeseen kuuluvan suojaavan kerroksen läpi, jollei sillä ole pääsyä nilaan. Tällainen kestävyys on tarpeen, jotta virus ei voi korvata nilakuljetusta solusta soluun leviämisellä. Tulokset tuovat uusia näkökulmia kasvien viruskestävyyteen ja auttavat selittämään viruksen nilakuljetuksen estymistä sekä solusta soluun leviämisen pysähtymistä kestävissä kasveissa.

Tax Reform and Payout Policy:Do Shareholder Clienteles or Payout Policy Adjust?

Changes in taxation of corporate dividends offer excellent opportunities to study dividend clientele effects. We explore payout policies and ownership structures around a major tax reform that took place in Finland in 2004. Consistent with dividend clienteles affecting firms’ dividend policy decisions, we find that Finnish firms altered their dividend policies based on the changed tax incentives of their largest shareholders. While firms adjust their payout policies, our results also indicate that ownership structures of Finnish firms also changed around the 2004 reform, consistent with shareholder clienteles adjusting to the new tax system.

IgG4 Autoantibodies to DNA in Systemic Lupus erythematosus Patients

The presence of DNA-specific IgG4 antibodies was demonstrated in the sera of patients with systemic lupus erythematosus (SLE) by a microtiter solid-phase radioimmunoassay. A patient with distal inter-phalangeal swelling and extensive ulcers in the oral cavity, seronegative for anti-DNA antibodies of the IgG isotype, was found to have anti-DNA autoantibodies exclusively of the IgG4 subclass. These autoantibodies directed against the dsDNA conformation cross-reacted with chondroitin sulfate, dermatan sulfate and heparin.

Influence of methylamine and N,N'-dimethylurea, the hydrolysis products of methyl isocyanate, on its systemic toxicity

Subcutaneous administration of the LD50 dose of methyl isocyanate (MIC) to rats induced severe hyperglycaemia, lactic acidosis and uraemia in rats. Neither methylamine (MA) nor N,N′-dimethylurea (DMU), the hydrolysis products of MIC, administered in equimolar doses had any influence on these parameters except for a marginal transient increase in plasma urea by DMU. Methyl isocyanate administration led to haemoconcentration, resulting in an increase in the plasma concentration of total proteins and a decrease in both the plasma concentration of albumin and the plasma cholinesterase activity. The hydrolysis products of MIC had no influence on any of these parameters. Thus, it seems reasonable to suggest that the systemic effects of MIC are caused by MIC per se, in spite of its high hydrolytic instability.

Roles of Salmonella enterica serovar Typhimurium encoded Peptidase N during systemic infection of Ifnγ(-/-) mice.

Pathogen encoded peptidases are known to be important during infection; however, their roles in modulating host responses in immunocompromised individuals are not well studied. The roles of S. typhimurium (WT) encoded Peptidase N (PepN), a major aminopeptidase and sole M1 family member, was studied in mice lacking Interferon-γ (IFNγ), a cytokine important for immunity. S. typhimurium lacking pepN (ΔpepN) displays enhanced colony forming units (CFU) compared to WT in peripheral organs during systemic infection in C57BL/6 mice. However, Ifnγ(-/-) mice show higher CFU compared to C57BL/6 mice, resulting in lower fold differences between WT and ΔpepN. Concomitantly, reintroduction of pepN in ΔpepN (ΔpepN/pepN) reduces CFU, demonstrating pepN-dependence. Interestingly, expression of a catalytically inactive PepN (ΔpepN/E298A) also lowers CFU, demonstrating that the decrease in CFU is independent of the catalytic activity of PepN. In addition, three distinct differences are observed between infection of C57BL/6 and Ifnγ(-/-) mice: First, serum amounts of TNFα and IL1β post infection are significantly lower in Ifnγ(-/-) mice. Second, histological analysis of C57BL/6 mice reveals that damage in spleen and liver upon infection with WT or ΔpepN is greater compared to ΔpepN/pepN or ΔpepN/E298A. On the other hand, Ifnγ(-/-) mice are highly susceptible to organ damage by all strains of S. typhimurium used in this study. Finally, greater survival of C57BL/6, but not Ifnγ(-/-) mice, is observed upon infection with ΔpepN/pepN or ΔpepN/E298A. Overall, the roles of the host encoded IFNγ during infection with S. typhimurium strains with varying degrees of virulence are highlighted.

Absence of systemic toxicity in mouse model towards BaTiO3 nanoparticulate based eluate treatment

One of the existing issues in implant failure of orthopedic biomaterials is the toxicity induced by the fine particles released during long term use in vivo, leading to acute inflammatory response. In developing a new class of piezobiocomposite to mimic the integrated electrical and mechanical properties of bone, bone-mimicking physical properties as well as in vitro cytocompatibility properties have been achieved with spark plasma sintered hydroxyapatite (HA)-barium titanate (BaTiO3) composites. However, the presence of BaTiO3 remains a concern towards the potential toxicity effect. To address this issue, present work reports the first result to conclusively confirm the non-toxic effect of HA-BaTiO3 piezobiocomposite nanoparticulates, in vivo. Twenty BALB/c mice were intraarticularly injected at their right knee joints with different concentrations of HA-BaTiO3 composite of up to 25 mg/ml. The histopathological examination confirmed the absence of any trace of injected particles or any sign of inflammatory reaction in the vital organs, such as heart, spleen, kidney and liver at 7 days post-exposure period. Rather, the injected nanoparticulates were found to be agglomerated in the vicinity of the knee joint, surrounded by macrophages. Importantly, the absence of any systemic toxicity response in any of the vital organs in the treated mouse model, other than a mild local response at the site of delivery, was recorded. The serum biochemical analyses using proinflammatory cytokines (TNF-alpha and IL-1 beta) also complimented to the non-immunogenic response to injected particulates. Altogether, the absence of any inflammatory/ adverse reaction will open up myriad of opportunities for BaTiO3 based piezoelectric implantable devices in biomedical applications.

Lack of Critical Slowing Down Suggests that Financial Meltdowns Are Not Critical Transitions, yet Rising Variability Could Signal Systemic Risk

Complex systems inspired analysis suggests a hypothesis that financial meltdowns are abrupt critical transitions that occur when the system reaches a tipping point. Theoretical and empirical studies on climatic and ecological dynamical systems have shown that approach to tipping points is preceded by a generic phenomenon called critical slowing down, i.e. an increasingly slow response of the system to perturbations. Therefore, it has been suggested that critical slowing down may be used as an early warning signal of imminent critical transitions. Whether financial markets exhibit critical slowing down prior to meltdowns remains unclear. Here, our analysis reveals that three major US (Dow Jones Index, S&P 500 and NASDAQ) and two European markets (DAX and FTSE) did not exhibit critical slowing down prior to major financial crashes over the last century. However, all markets showed strong trends of rising variability, quantified by time series variance and spectral function at low frequencies, prior to crashes. These results suggest that financial crashes are not critical transitions that occur in the vicinity of a tipping point. Using a simple model, we argue that financial crashes are likely to be stochastic transitions which can occur even when the system is far away from the tipping point. Specifically, we show that a gradually increasing strength of stochastic perturbations may have caused to abrupt transitions in the financial markets. Broadly, our results highlight the importance of stochastically driven abrupt transitions in real world scenarios. Our study offers rising variability as a precursor of financial meltdowns albeit with a limitation that they may signal false alarms.

Caspase-3-dependent phagocyte death during systemic Salmonella enterica serovar Typhimurium infection of mice.

Growth of Salmonella enterica in mammalian tissues results from continuous spread of bacteria to new host cells. Our previous work indicated that infective S. enterica are liberated from host cells via stochastic necrotic burst independently of intracellular bacterial numbers. Here we report that liver phagocytes can undergo apoptotic caspase-3-mediated cell death in vivo, with apoptosis being a rare event, more prevalent in heavily infected cells. The density-dependent apoptotic cell death is likely to constitute an alternative mechanism of bacterial spread as part of a bet-hedging strategy, ensuring an ongoing protective intracellular environment in which some bacteria can grow and persist.
