Double ionisation of most of the experimentally accessible diatomic molecules has been studied previously by several techniques, including Auger spectroscopy, double electron transfer, kinetic energy release, and high-level theory. New double photoionisation spectra of HBr, HI, N2, CO, NO, O2, Br2, ICl, and I2 are presented here with analysis to identify the electronic states of the doubly charged ions. A simple empirical model is introduced to estimate double ionisation energies on the basis of orbital energies. For CO, NO, and O2, an indirect double ionisation mechanism is found, involving dissociation of a singly charged molecular ion followed by atomic autoionisation of one fragment. Energies of the dication states are listed with distinction between adiabatic and vertical values.

In 2008, the Canadian government established a Truth and Reconciliation Commission (TRC) to review the history of the residential school system, a brutal colonial project that killed and injured many Indigenous children and left a legacy of trauma and pain. In Fragments of Truth Naomi Angel analyzes the visual culture of reconciliation and memory in relation to this complex and painful history. In her analyses of archival photographs from the residential school system, representations of the schools in popular media and literature, and testimonies from TRC proceedings, Angel traces how the TRC served as a mechanism through which memory, trauma, and visuality became apparent. She shows how many Indigenous communities were able to use the TRC process as a way to claim agency over their memories of the schools. Bringing to light the ongoing costs of transforming settler states into modern nations, Angel demonstrates how the TRC offers a unique optic through which to survey the long history of colonial oppression of Canada’s Indigenous populations.

This book pioneers a new model of personality disorder primarily intended to serve mental health professionals, those already in practice and equally those in training. In contrast to the static concepts of mental normalcy and pathology, the presented nosology is dynamic (accounts for the reversibility of mental functioning) and personalized, context- and time sensitive. In a 3D diagnostic cylinder, the coordinates cross match the person’s common level of mental functioning (vertical diagnosis) with his or her behavior style (horizontal diagnosis) at a point in space and a unit of time, giving the clinician precise milestones to monitor changes in diagnosis and progress in therapy. The central problem with persons suffering from personality disorder does not rest in their extreme behaviors but rather underneath the surface, in the fragmented substrate of personality (a core deficit sine qua non shared by all individual variants), while extreme behaviors merely represent variable compensatory strategies. Based on this model, mechanism-based treatments are outlined: reconstructive interpersonal psychotherapy (a novel, integrative, transtheoretical approach which relies on psychoanalytic and humanist traditions) and mechanism-based pharmacotherapy of neurobiological vulnerabilities associated with excessive temperament traits.

The Introduction presents the overarching research question of the book, namely the question of whether and how war between nations has influenced the development of advanced welfare states. This question has received only scant attention from the welfare state literature so far. The Introduction reviews the fragmented literature in history and social science with a focus on national narratives and revisionist positions, and argues for a comparative angle which puts the various causal mechanisms linking mass war and welfare state development. These mechanisms are systematized, using a heuristic of supply- vs. demand-side mechanisms and three distinct phases of military conflict: war preparation, mobilization, and the post-war period.

The 3,144–amino acid huntingtin protein (HTT) folds in water into a structure consisting of compact, organized domains interspersed with intrinsically disordered protein (IDP) elements. The IDPs function as sites of post-translational modifications and proteolysis as well as in targeting, binding, and aggregation. Although the dominant structural motif of HTT is the α‎-helix–rich HEAT repeat, the expanded polyglutamine (polyQ) toxicity responsible for Huntington’s disease is most likely played out within intrinsically disordered HTT exon 1–like fragments consisting of the 16– to 17–amino acid N-terminal HTTNT segment, the polyQ segment, and a proline-rich segment. The physical behavior of HTT exon 1 fragments is dominated by interactive, polyQ repeat length–dependent structural transitions responsible for membrane and protein–protein interactions and the formation of tetramers, higher oligomers, amyloid fibrils, and inclusions. Understanding the basis of this solution behavior may be the key to disease mechanisms and molecular therapeutic strategies.

This chapter analyzes the Lebanese Constitution in the light of consociational democracy. It begins with an overview on the political system to highlight the formal consensus requirements based on affiliation with one of the main religious groups in the country. It examines the evolution of confessional power-sharing, which is supplemented by the traditional family-based feudal lord system. It then explores the historical interplay of state-building, civil wars, and existing political frictions which still contribute to what the Lebanese Constitution is about today. Next, the chapter outlines the constitutional development regarding consociational democracy, emphasizing the different consensus-mechanisms now incorporated in the written constitution. This shows how the Lebanese political system diverges from the classical Montesquieu system and creates its own separation of powers through consensus mechanisms.

Bolivia’s natural resources have served as a ‘mechanism of trade’ mobilized by competing interest groups to build coalitions, create political pacts, and negotiate political settlements in which dominant actors attempt to win over those resistant to a particular vision of development and/or governance. These pacts and settlements are revisited constantly, reflecting the weak and fragmented power of the central state and of the elite and persistent tensions between national and subnational elites. Ideas about, and modes of, natural resource governance have been central to periods of instability and stability, and to significant periods of political rupture. The period since 2006 has been characterized by a stable settlement involving an alliance between the presidency, his dominant party, and national social movements. This settlement is sustained through bargains with parts of the economic elite and subnational actors with holding power, as well as through ideas of resource nationalism and state-led developmentalism.

The 1982 United Nations Convention on the Law of the Sea (UNCLOS) remains the cornerstone of global ocean governance. However, it lacks effective provisions or mechanisms to ensure that all ocean space and related problems are dealt with holistically. With seemingly no opportunity for revision due to the Conventions burdensome amendment provisions, complementary mechanisms dealing with such aspects of global ocean governance including maritime transport, fisheries, and marine environmental sustainability, have been developed under the aegis of the United Nations and other relevant international organizations. This approach is inherently fragmented and unable to achieve sustainable global ocean governance. In light of the Sustainable Development Goals (SDGs), particularly Goal 14, the IMLI Treatise proposes a new paradigm on the basis of integrated and cross-sectoral approach in order to realise a more effective and sustainable governance regime for the oceans. The volume examines how the IMO, with 171 Member States and 3 Associated Members, has and continues to promote the goals of safe, secure, sound, and efficient shipping on clean oceans. It studies the interface and interaction between UNCLOS and IMO instruments and how the IMO’s safety, security, and environmental protection conventions have contributed to global ocean governance, including the peaceful order of the polar regions.

It examines the ocean governance challenges and how the present legal, policy, and institutional frameworks of the UN have addressed these challenges. It identifies the strengths and weaknesses of UN legal structures and offers tangible proposals to realize the ambition of a global ocean governance system.

This chapter is dedicated to the challenges which the VCDR, fifty years into its existence, faces in a world marked by a globalized economy and rapid technological developments. The author reflects on new diplomatic processes which have emerged through the creation of governmental and non-governmental institutions and on notions such as collaborative, public, and cultural diplomacy which have challenged accepted understandings of the role and functions of traditional diplomacy. Barker also explores the fact that international law itself is changing from a system regulating co-existing sovereignties to a possibly fragmented discourse of complex frameworks which themselves challenge the sovereignty paradigm. In this context, he investigates the continued relevance and purpose of the VCDR and gives particular focus to existing mechanisms within the Convention that allow for modified and developed interpretations of the Convention to take account of the changing international world in which contemporary diplomacy operates.

This chapter examines how the structural provisions of the American Constitution and the federalist system of government they create uniquely shape the landscape of regulation for technology in the United States. The chapter’s inquiry focuses on the biomedical technologies associated with assisted reproduction and embryo research. These areas present vexing normative questions about the introduction and deployment of these technologies, showing the mechanisms, dynamics, virtues, and limits of the federalist system of government for the regulation of technology. In particular, the differing jurisdictional scope of federal and state regulation results in overlap and interplay between the two regulatory systems. The consequence of this dynamic is often a wide divergence in judgments about law and public policy. The chapter’s review of the constitutionally fragmented regime currently regulating different biotechnologies questions whether such a decentralized approach is well suited to technologies that involve essential moral and ethical judgments about the human person.

The successful use of special economic zones as economic tools for export-led industrial development in East Asia propelled a wave of similar initiatives across Africa. In Southern Africa, Zambia and South Africa instituted special economic zones in their respective legal and institutional frameworks in the 2000s as mechanisms for catalysing industrialization and employment creation by means of domestic and foreign investments. Using a case-study approach, we find that special economic zones in the Eastern Cape, South Africa, are largely latent drivers of growth and employment hampered by inadequate infrastructure financing and provision and weak local supplier capabilities. Special economic zones in Lusaka, Zambia, face similar constraints but are further hampered by inadequate business services provision, burdensome regulations and business procedures, a fragmented incentive framework, institutional coordination failures, and a weak design that does not leverage strategic anchor industries for greater agglomeration economies, thus rendering them more of white elephants.

This chapter explores the interplay between politics and international law in the field of climate finance, with an emphasis on its North-South dimensions, which is the promotion of resource flows by developed nations towards developing nations. Participation by developing countries in the climate regime is critical as they are the largest emitters of greenhouse gas. Unfortunately, it is the less-developed nations that are harmed the most by climate change. It is here where North-South finance emerges as an important issue. The chapter addresses two critical issues in the governance and future of the climate finance regime. First, the wide variety of institutions and mechanisms involved expands the scope for attracting and supplying resources but they remain fragmented and require greater coordination to be effective. Second, the mobilization of North-South finance is insufficient relative to mitigation and adaptation needs. Such a challenge requires greater political will and a stronger legal regime.

This book critically engages the shortcomings of the field of international heritage law, seen through the lenses of the five major UNESCO treaties for the safeguarding of different types of heritage. It argues that these five treaties have, by design or in their implementation, effectively prevented local communities, who bear the brunt of the costs associated with international heritage protection, from having a say in how their heritage is managed. The exclusion of local communities often alienates them not only from international decision-making processes but also from their cultural heritage itself, ultimately meaning that systems put in place for the protection of cultural heritage contribute to its disappearance in the long term. The book adds to existing literature by looking at these UNESCO treaties not as isolated regimes, which is the common practice in the field, but rather as belonging to a discursive continuum on cultural heritage. Rather than scrutinizing the regimes themselves, the book focuses on themes that cut across the relevant UNESCO regimes, such as the use of expert rule in international heritage law, economics, and the relationship between heritage and the environment. It uses this mechanism to highlight the blind spots and unintended consequences of UNESCO treaties and how choices made in their drafting have continuing and potentially negative impacts on how we think about and safeguard heritage. The book is of interest to cultural heritage scholars and practitioners across all disciplines, as well as to international lawyers interested in the dynamics of fragmented subfields.

What is at stake for how the Internet continues to evolve is the preservation of its integrity as a single network. In practice, its governance is neither centralized nor unitary; it is piecemeal and fragmented, with authoritative decision-making coming from different sources simultaneously: governments, businesses, international organizations, technical and academic experts, and civil society. Historically, the conditions for their interaction were rarely defined beyond basic technical coordination, due at first to the academic freedom granted to the researchers developing the network and, later on, to the sheer impossibility of controlling mushrooming Internet initiatives. Today, the search for global norms and rules for the Internet continues, be it for cybersecurity or artificial intelligence, amid processes fostering the supremacy of national approaches or the vitality of a pluralist environment with various stakeholders represented. This book provides an incisive analysis of the emergence and evolution of global Internet governance, unpacking the complexity of more than 300 governance arrangements, influential debates, and political negotiations over four decades. Highly accessible, this book breaks new ground through a wide empirical exploration and a new conceptual approach to governance enactment in global issue domains. A tripartite framework is employed for revealing power dynamics, relying on: (a) an extensive database of mechanisms of governance for the Internet at the global and regional level; (b) an in-depth analysis of the evolution of actors and priorities over time; and (c) a key set of dominant practices observed in the Internet governance communities. It explains continuity and change in Internet-related negotiations, opening up new directions for thinking and acting in this field.

The turn of the 20th and 21st centuries has been a very dynamic period of change in Poland and around the world; also a period of change in thinking about the economy and agriculture. The present work is a study of the decline, divestments and development of agriculture in the areas of fragmented farming structure. The reflections presented herein, upon the processes of the remodelling of agrarian structures, of divestments in farming, and disagrarisation, are mostly anchored in the achievements of the theory of spatial economy (land management), and the microeconomic theories of choice, including the theory of an agricultural holding (farm) and land rent theories. The work focuses on the economic issues of remodelling the agrarian structure, but due to the nature of the issues discussed herein, specifically in relation to family-owned farms, the social and environmental aspects also needed to be taken into account – in response to the need for a heterogeneous approach, which is increasingly stressed in economic sciences today. The main objective of the research was to diagnose and assess the scale and scope of the mechanisms and processes that inform the decline and growth of agricultural holdings in the areas with fragmented farming structure. The study covered the area comprising four regions (provinces) of south-eastern Poland, which – according to the FADN nomenclature – form the macro region of Małopolska and Pogórze. The study of subject literature has been enriched with an analysis of available statistics; data from the Farm Accountancy Data Network (FADN); information obtained from the Department of Programming and Reporting at the Agency for Restructuring and Modernisation of Agriculture; and author’s own research conducted among farm owners. The information thus obtained made it possible to: • Determine the theoretical premises for the spatial diversity of agriculture, and the role of small farms in the shaping of agrarian structure. • Adapt the concept of “divestment” for the description and analysis of the phenomena occurring in agriculture. • Indicate the role and importance of the processes of divestment and disagrarisation in the restructuring of agriculture. • Assess the natural, social and economic determinants of the process of restructuring agriculture in areas with fragmented farming structure. • Assess selected aspects of economic efficiency of agriculture in areas with fragmented farming structure, with the focus on small and micro farms. • Carry out an ex ante evaluation of the impact of agricultural policy instruments on the process of restructuring of agriculture in the macro region of Małopolska and Pogórze. • Identify the indicators of decline and fall, and barriers to the liquidation of farms. • Assess the relationship between the level of socio-economic development, the structure of farming, and the quality of agricultural production space in a given territorial unit, versus the intensity of the economic and production disagrarisation processes in agricultural holdings. • Propose targeted solutions conducive to the improvement of the farming structure in areas with a high framentation of agriculture. Observation of the processes occurring in agriculture, and the scientific theories created on the basis thereof, have shown that even the smallest farms have a chance to continue in existence, provided that we are able to positively verify their adaptation to the changing conditions in the environment. Carrying out farming activity is a prerequisite for implementing the economic, social and environmental functions associated with family farms. At the same time, based on the analyses performed, we need to assume that the advanced processes of the production and economic disagrarisation of agricultural holdings are to a greater extent determined by the anatomical features of agriculture, and by the natural conditions, than by the level of socio-economic development of the given territorial unit. In the current economic climate, the remodelling of the agrarian structure is only possible with the active participation of the institutions responsible for the creation of economic growth and agricultural policy development. It is extremely important from the point of view of environmental protection, and the viability of rural areas, to support small farms engaged in agricultural activities, and to introduce such instruments that will enable the replacement of an economic collapse with divestments, carried out in a planned manner, and allowing for thus released agricultural resources to find alternative application in units with a higher development potential. The area of theoretical research requiring further exploration includes the issues such as transactional costs of the liquidation of agricultural holdings, and the assessment of the economic effectiveness of conducting divestments.

The aim of the paper was to determine the influence of root systems of chosen tree species found in the Polish Flysch Carpathians on the increase of soil shear strength (root cohesion) in terms of slope stability. The paper's goal was achieved through comprehensive tests on root systems of eight relatively common in the Polish Flysch Carpathians tree species. The tests that were carried out included field work, laboratory work and analytical calculations. As part of the field work, the root area ratio (A IA) of the roots was determined using the method of profiling the walls of the trench at a distance of about 1.0 m from the tree trunk. The width of the. trenches was about 1.0 m, and their depth depended on the ground conditions and ranged from 0.6 to 1.0 m below the ground level. After preparing the walls of the trench, the profile was divided into vertical layers with a height of 0.1 m, within which root diameters were measured. Roots with diameters from 1 to 10 mm were taken into consideration in root area ratio calculations in accordance with the generally accepted methodology for this type of tests. These measurements were made in Biegnik (silver fir), Ropica Polska (silver birch, black locust) and Szymbark (silver birch, European beech, European hornbeam, silver fir, sycamore maple, Scots pine, European spruce) located near Gorlice (The Low Beskids) in areas with unplanned forest management. In case of each tested tree species the samples of roots were taken, transported to the laboratory and then saturated with water for at least one day. Before testing the samples were obtained from the water and stretched in a. tensile testing machine in order to determine their tensile strength and flexibility. In general, over 2200 root samples were tested. The results of tests on root area ratio of root systems and their tensile strength were used to determine the value of increase in shear strength of the soils, called root cohesion. To this purpose a classic Wu-Waldron calculation model was used as well as two types of bundle models, the so called static model (Fiber Bundle Model — FIRM, FBM2, FBM3) and the deformation model (Root Bundle Model— RBM1, RBM2, mRBM1) that differ in terms of the assumptions concerning the way the tensile force is distributed to the roots as well as the range of parameters taken into account during calculations. The stability analysis of 8 landslides in forest areas of Cicikowicleie and Wignickie Foothills was a form of verification of relevance of the obtained calculation results. The results of tests on root area ratio in the profile showed that, as expected, the number of roots in the soil profile and their ApIA values are very variable. It was shown that the values of the root area ratio of the tested tree species with a diameter 1-10 ram are a maximum of 0.8% close to the surface of the ground and they decrease along with the depth reaching the values at least one order of magnitude lower than close to the surface at the depth 0.5-1.0 m below the ground level. Average values of the root area ratio within the soil profile were from 0.05 to 0.13% adequately for Scots pine and European beech. The measured values of the root area ratio are relatively low in relation to the values of this parameter given in literature, which is probably connected with great cohesiveness of the soils and the fact that there were a lot of rock fragments in the soil, where the tests were carried out. Calculation results of the Gale-Grigal function indicate that a distribution of roots in the soil profile is similar for the tested species, apart from the silver fir from Bie§nik and European hornbeam. Considering the number of roots, their distribution in the soil profile and the root area ratio it appears that — considering slope stability — the root systems of European beech and black locust are the most optimal, which coincides with tests results given in literature. The results of tensile strength tests showed that the roots of the tested tree species have different tensile strength. The roots of European beech and European hornbeam had high tensile strength, whereas the roots of conifers and silver birch in deciduous trees — low. The analysis of test results also showed that the roots of the studied tree species are characterized by high variability of mechanical properties. The values Of shear strength increase are mainly related to the number and size (diameter) of the roots in the soil profile as well as their tensile strength and pullout resistance, although they can also result from the used calculation method (calculation model). The tests showed that the distribution of roots in the soil and their tensile strength are characterized by large variability, which allows the conclusion that using typical geotechnical calculations, which take into consideration the role of root systems is exposed to a high risk of overestimating their influence on the soil reinforcement. hence, while determining or assuming the increase in shear strength of soil reinforced with roots (root cohesion) for design calculations, a conservative (careful) approach that includes the most unfavourable values of this parameter should be used. Tests showed that the values of shear strength increase of the soil reinforced with roots calculated using Wu-Waldron model in extreme cases are three times higher than the values calculated using bundle models. In general, the most conservative calculation results of the shear strength increase were obtained using deformation bundle models: RBM2 (RBMw) or mRBM1. RBM2 model considers the variability of strength characteristics of soils described by Weibull survival function and in most cases gives the lowest values of the shear strength increase, which usually constitute 50% of the values of shear strength increase determined using classic Wu-Waldron model. Whereas the second model (mRBM1.) considers averaged values of roots strength parameters as well as the possibility that two main mechanism of destruction of a root bundle - rupture and pulling out - can occur at the same. time. The values of shear strength increase calculated using this model were the lowest in case of beech and hornbeam roots, which had high tensile strength. It indicates that in the surface part of the profile (down to 0.2 m below the ground level), primarily in case of deciduous trees, the main mechanism of failure of the root bundle will be pulling out. However, this model requires the knowledge of a much greater number of geometrical parameters of roots and geotechnical parameters of soil, and additionally it is very sensitive to input data. Therefore, it seems practical to use the RBM2 model to assess the influence of roots on the soil shear strength increase, and in order to obtain safe results of calculations in the surface part of the profile, the Weibull shape coefficient equal to 1.0 can be assumed. On the other hand, the Wu-Waldron model can be used for the initial assessment of the shear strength increase of soil reinforced with roots in the situation, where the deformation properties of the root system and its interaction with the soil are not considered, although the values of the shear strength increase calculated using this model should be corrected and reduced by half. Test results indicate that in terms of slope stability the root systems of beech and hornbeam have the most favourable properties - their maximum effect of soil reinforcement in the profile to the depth of 0.5 m does not usually exceed 30 kPa, and to the depth of 1 m - 20 kPa. The root systems of conifers have the least impact on the slope reinforcement, usually increasing the soil shear strength by less than 5 kPa. These values coincide to a large extent with the range of shear strength increase obtained from the direct shear test as well as results of stability analysis given in literature and carried out as part of this work. The analysis of the literature indicates that the methods of measuring tree's root systems as well as their interpretation are very different, which often limits the possibilities of comparing test results. This indicates the need to systematize this type of tests and for this purpose a root distribution model (RDM) can be used, which can be integrated with any deformation bundle model (RBM). A combination of these two calculation models allows the range of soil reinforcement around trees to be determined and this information might be used in practice, while planning bioengineering procedures in areas exposed to surface mass movements. The functionality of this solution can be increased by considering the dynamics of plant develop¬ment in the calculations. This, however, requires conducting this type of research in order to obtain more data.
