<p>This thesis looks at Wellington's Waitangi Park, through the specifics of the Chaffers Park Design Competition, in order to explore the repercussions mistrust can have on social vision and political response. In examining aspects of this competition over a piece of public land, and comparing various accounts of events leading up to it, an interpretative impasse is reached that factual explanations alone cannot minimise. Because the search for truth proves elusive, other forms of evidence must be relied upon as sources of knowledge. In this instance, an analysis of experiences demonstrates the effect differing expectations has on human interaction, ones that are shown to have a significant impact on placemaking processes and organizational structures. When debates over public land degenerate into power struggles, the issue of control is brought to the forefront of attention. It raises questions concerning who owns public land, whether it properly belongs to local authorities or the public itself. Who gets to designate how these spaces are used, and select what ought and ought not to go on these sites? Here, the issue of representation is troublesome because so many different groups claim to speak for the public's interest, leaving the reader wondering whose interpretation to believe and place trust in. Where the perception is that democratic rights are being undermined, then doubt in the principles underpinning consultation processes soon emerges. And once mistrust becomes entrenched, organizational tinkering is not sufficient in itself to reverse a negative state of affairs; only joint satisfaction will do. But if satisfaction proves unforthcoming, then a withdrawal from engagement can be anticipated as committed individuals quit the field in disillusionment. This in turn causes a narrowing of vision and leads to uncreative political responses traits associated with acts of obliviousness.</p>

This paper establishes an empirical relationship between CO2 emissions from burning fossil fuels and household consumption of nondurable goods and services. Using a typical life cycle-permanent income hypothesis framework, we reject the hypothesis that inclusion of CO2 emissions in the consumption function is not supported by the data. Furthermore, our results suggest the existence of a distaste effect or negative state dependence effect. This result has important policy implications as it suggests that decarbonizing the economy would ultimately stimulate household consumption. Our results also have implications for both the cyclical behavior and the smoothing process of consumption, which depend on the branch of the environmental Kuznets curve that the country is on as well as on the prevalence of intertemporal dependent preferences.

The use of entangled sensors improves the precision limit from the standard quantum limit (SQL) to the Heisenberg limit. Most previous experiments beating the SQL are performed on the sensors that are well isolated under extreme conditions. Here, we demonstrate a sub-SQL interferometer at ambient conditions by using a multispin system, namely, the nitrogen-vacancy (NV) defect in diamond. We achieve two-spin interference with a phase sensitivity of 1.79 ± 0.06 dB beyond the SQL and three-spin interference with a phase sensitivity of 2.77 ± 0.10 dB. Besides, a magnetic sensitivity of 0.87 ± 0.09 dB beyond the SQL is achieved by two-spin interference for detecting a real magnetic field. Particularly, the deterministic and joint initialization of NV negative state, NV electron spin, and two nuclear spins is realized at room temperature. The techniques used here are of fundamental importance for quantum sensing and computing, and naturally applicable to other solid-state spin systems.

Issues on the implementation of intellectual property analysis in Ukraine, as well as a forensic expert participation in court hearing abroad were considered. Intellectual property objects belong to a variety of types of art, science, technology and crafts, effective consideration of cases related to protection of intellectual property rights, for a complete and comprehensive study of the subject of examination and providing an expert's concusion becomes possible only in case of attracting specialists, who have special knowledge in a particular field. The article purpose is to define features of intellectual property analysis in Ukraine and formal requirements for a forensic expert in Ukraine and foreign states. One of the priority directions of state policy is the protection of intellectual property rights, as the development of this area stimulates innovation in all fields by increasing the country's economy to a new level, and providing it a rightful place at the international level. Also, an increase of scientific potential not only promotes Ukraine's modernization in various fields of science and technology but also increases its defense capability and national security. Today there is a negative state of compliance with the legislation regulating intellectual property issues, the number of violations of relevant rights is increasing. The reason for such a state is the imperfection of the mechanism of legal protection and protection of intellectual property rights in the field of scientific activity, failure to resolve the issue regarding legal protection of scientific advances, etc. In January 2020, the European Commission made a publication of a report on protection and ensuring intellectual property rights in third countries, according to which (despite all preventive measures) our country was already on the list of countries, where there are serious systematic problems in the field of defense and protection of intellectual rights, causing significant damage to the economic interests of the EU. Forensic science plays a priority role in introducing advanced achievements of science and technology and promotes the reliability of the proof system in the case. In some cases, the appointment and conduct of a forensic examination are not only necessary but also the only possible means of establishing the truth and solving a litigation.

 In the oil and gas industry, the geophysics bears the most knowledge-intensive and high-tech activity. The results of geophysical studies underlie the search, exploration and development of oil and gas fields. It is impossible to effectively drill, operate and repair wells without it. Success in the development of technology and technology in geophysics depends on the level of academic and industrial science, the effectiveness of the education system, and the intellectual training of personnel. The paper provides a historical insight into the era of geophysical research from the beginning of the last century to the present day. The current state and prospects of further development of the geophysical industry as the basis of Ukraine’s energy independence are analyzed. The main reasons for the negative state of affairs in Ukrainian geophysics are as follows: loss of professionalism, lack of high-quality basic education, lack of funding and short-sighted decision-making.

In non-promyelocytic (non-M3) AML measurable residual disease (MRD) detected by multi-parameter flow cytometry and molecular technologies, which are guided by Consensus-based guidelines and discover very low leukemic cell numbers far below the 5% threshold of morphological assessment, has emerged as the most relevant predictor of clinical outcome. Currently, it is well-established that MRD positivity after standard induction and consolidation chemotherapy, as well as during the period preceding an allogeneic hematopoietic stem cell transplant (allo-HSCT), portends to a significantly inferior relapse-free survival (RFS) and overall survival (OS). In addition, it has become absolutely clear that conversion from an MRD-positive to an MRD-negative state provides a favorable clinical outcome similar to that associated with early MRD negativity. Thus, the complete eradication of MRD, i.e., the clearance of the few leukemic stem cells—which, due to their chemo-radiotherapy resistance, might eventually be responsible of disease recurrence—has become an un-met clinical need in AML. Nowadays, this goal might potentially be achieved thanks to the development of novel innovative treatment strategies, including those targeting driver mutations, apoptosis, methylation patterns and leukemic proteins. The aim of this review is to analyze these strategies and to suggest any potential combination able to induce MRD negativity in the pre- and post-HSCT period.

Negativity of the Wigner function is arguably one of the most striking non-classical features of quantum states. Beyond its fundamental relevance, it is also a necessary resource for quantum speedup with continuous variables. As quantum technologies emerge, the need to identify and characterize the resources which provide an advantage over existing classical technologies becomes more pressing. Here we derive witnesses for Wigner negativity of single mode and multimode quantum states, based on fidelities with Fock states, which can be reliably measured using standard detection setups. They possess a threshold expectation value indicating whether the measured state has a negative Wigner function. Moreover, the amount of violation provides an operational quantification of Wigner negativity. We phrase the problem of finding the threshold values for our witnesses as an infinite-dimensional linear optimisation. By relaxing and restricting the corresponding linear programs, we derive two hierarchies of semidefinite programs, which provide numerical sequences of increasingly tighter upper and lower bounds for the threshold values. We further show that both sequences converge to the threshold value. Moreover, our witnesses form a complete family – each Wigner negative state is detected by at least one witness – thus providing a reliable method for experimentally witnessing Wigner negativity of quantum states from few measurements. From a foundational perspective, our findings provide insights on the set of positive Wigner functions which still lacks a proper characterisation.
