Abstract:

Transitions in the dike revetment or in the grass cover can significantly affect the wave overtopping discharge and the dike cover erosion. At the University of Twente, two PhD students recently started on the challenge of quantifying the effect of (1) waterside transition on the wave overtopping discharge and (2) transitions in grass covered dikes on dike erosion. In this paper we present their preliminary results and outline their future plans. Firstly, new laboratory experiments show that the existing wave overtopping formulas are not able to accurately predict the overtopping discharge in case of transitions on the waterside slope. Secondly, the analytical dike cover erosion model shows that transitions in grass covers significantly affect the location of maximum flow velocity and potential dike cover erosion. In future work, detailed numerical models will be developed for both the waterside slope and the landward slope to further increase our understanding of the effects of transitions on the wave overtopping discharge and the dike cover erosion.

Abstract:

Purpose This paper provides an overview of transitions across forensic child and adolescent mental health services in England and Wales. The purpose of this paper is to delineate the national secure services system for young people in contact with the youth justice system. Design/methodology/approach This paper reviews findings from the existing literature of transitions across forensic child and adolescent mental health services, drawing attention to present facilitators and barriers to optimal transition. The authors examine the infrastructure of current services and highlight gaps between child and adult service continuity and evaluate the impact of poor transitions on young offenders’ mental health and wellbeing. Findings Young offenders experience a broad range of difficulties, from the multiple interfaces with the legal system, untreated mental health problems, and poor transition to adult services. Barriers such as long waiting lists, lack of coordination between services and lack of transition preparation impede significantly smooth transitions. Research limitations/implications The authors need to develop, test and evaluate models of transitional care that improve mental health and wellbeing of this group. Practical implications Mapping young offenders’ care pathway will help to understand their needs and also to impact current policy and practice. Key workers in forensic services should facilitate the transition process by developing sustainable relationships with the young person and creating a safe clinical environment. Originality/value Transition of care from forensic child and adolescent mental health services is a neglected area. This paper attempts to highlight the nature and magnitude of the problems at the transition interface in a forensic context.

Abstract:

Batch processes are carried out from one steady phase to another one, which may have multiphase and transitions. Modeling in transitions besides in the steady phases should also be taken into consideration for quality prediction. In this paper, a quality prediction strategy is proposed for multiphase batch processes. First, a new repeatability factor is introduced to divide batch process into different steady phases and transitions. Then, the different local cumulative models that considered the cumulative effect of process variables on quality are established for steady phases and transitions. Compared with the reported modeling methods in transitions, a novel just-in-time model can be established based on the dominant phase identification. The proposed method can not only consider the dynamic characteristic in the transition but also improve the accuracy and the efficiency of transitional models. Finally, online quality prediction is performed by accumulating the prediction results from different phases and transitions. The effectiveness of the proposed method is demonstrated by penicillin fermentation process.

Abstract:

In this paper we consider an approach, which allows the research of order-disorder transitionin lattice systems (with any distribution of the exchange integrals) in the frame of Ising model. Anew order parameters, which can give a description of a phase transitions, are found. The commondefinition of such order parameter is the mean value of percolation cluster size. Percolation clusterincludes spins in ground state. The transition from absolute disorder to correlated phase could bestudied with using of percolation theory methods.

Abstract:

This paper presents millimeter wave characterization and models of various wire bond transitions between chip’s ground-signal-ground pad (GSG) and microstrip (MS), include single-wire-nomatch MS-GSG transition, double-wire-nomatch MS-GSG, single-wire-match MS-GSG transition, and double-wire-match MS-GSG transition. It also presents the 3D full-wave electromagnetic simulation. Analysis results show that the double-wire-match MS-GSG transition’s characteristic is better than other three transitions in the whole W band. The accurate extracted parameter values are used for the lumped equivalent circuit model, whose simulation results are good with the full wave simulation results. The error between lumped equivalent circuit and full-wave models is of the order of ±0.2dB for S11 and S21 in the frequency range 75 - 105GHz. The proposed lumped equivalent circuit is suitable to be implemented in commercial microwave CAD tools for the electromagnetic sensor designing.

Abstract:

This paper reports the results of a literature review of health care organizations that have transitioned from one electronic health record (EHR) to another. Ten different EHR to EHR transitions are documented in the academic literature. In eight of the 10 transitions, the health care organization transitioned to Epic, a commercial EHR which is dominating the market for large and medium hospitals and health care systems. The focus of the articles reviewed falls into two main categories: (1) data migration from the old to new EHR and (2) implementation of the new EHR as it relates to patient safety, provider satisfaction, and other measures pre-and post-transition. Several conclusions and recommendations are derived from this review of the literature, which may be informative for healthcare organizations preparing to replace an existing EHR. These recommendations are likely broadly relevant to EHR to EHR transitions, regardless of the new EHR vendor.

Full text

Abstract:

Finding ways to understand, analyze, and manage sustainability transitions is a fundamental challenge for sustainability science. In this paper, we show how we can substantially deepen our understanding of factors that determine the success of sustainability transitions by combining two key concepts from the resilience literature—stability and adaptability—with a dynamic understanding of the progress of socio-technical transitions. We propose a conceptual perspective for sustainability transitions, the resilience of sustainability transitions (RST) concept, which integrates progress, stability, and adaptability as key dimensions to comprehend the dynamics of sustainability transitions. In a case analysis of the energy transition process in the Austrian region of Weiz-Gleisdorf, we apply the concept. In doing so, we illustrate how RST thinking helps identify and understand crucial elements that influence the dynamics of a sustainability transition process.

Abstract:

This paper traces the transition from planned command socialism to market capitalism and the accompanying complex non-linear dynamics involved. Long wave chaotic hysteretic investment cycles emerge under socialism leading to crisis and breakdown. Macroeconomic collapse occurs with bifurcations of coordination structures during transition. During recovery, transitional cobweb labor market dynamics exhibit chaos, fractal basin boundaries between coexisting non-chaotic attractors, discontinuous phase transitions, strange attractors, and cascades of infinitely many period-doubling bifurcations.

Abstract:

This paper discusses the usefulness of indepth life history interviews in illustrating the role of social structure and human agency in youth transitions. Drawing on sociological theory and youth transition research, the paper highlights how the role of structure and agency has been perceived by youth researchers. Whilst this literature acknowledges the interplay between structure and agency in transitional processes, the appropriateness of particular research methods for explicating structure and agency needs to be further elucidated. Using data from a study of youth transitions in rural areas of Scotland, a range of transitional experiences from two indepth life history interviews is presented here. This exploratory exercise suggests that life history interviews enable researchers to explore how far social structures provide opportunities and constraints for human agents at the same time as showing how individuals, with their own beliefs and desires, take actions despite the social structures that underlie the immediacy of their experiences.

Full text

Abstract:

Purpose – The purpose of this paper is to explore the experience of senior leaders who move into the public sector from other sectors of the economy, a process referred to in this paper as inter-sector senior leader transitions. This is a little researched area of public sector leadership yet has significant implications for fundamental public sector reform. Design/methodology/approach – The paper employs an interview design to elicit senior leaders' stories of their transition into the public sector. Findings – The data suggest that successful senior leader transitions are more likely when a set of conditions is met; the leader transitions into CEO role, rather than levels below CEO, ministers provide inter-sector transition support, senior leaders develop responses to stress, senior leaders reject high formalization, their change processes focus on building capacity, and senior leaders confront dysfunctional organizational relationships directly. Research limitations/implications – The research relies on a relatively small sample. However, access to senior managers at this level can be difficult. Nevertheless, those senior managers who participated were very willing to share their stories. Practical implications – If public sector organizations are to realize the value of successful leaders from other sectors, they need to invest in structured processes that facilitate the transition. A laissez-faire approach is not viable given the cost of such transitions. Originality/value – The paper focuses on a little researched area of leadership experience which has significant implications for the development and change of the public sector.

Abstract:

This paper sets out a series of principles for minimising the trauma of transitions experienced by children in out of home care. It is based on a child centred approach that has as its goal making transition bearable and psychologically useful for each child who must go through it, creating a space where even previous transition wounds might heal. The paper concentrates particularly on the complexities of helping children to move between foster care and permanent care placements.

Abstract:

Writing at a time when the literature on transitions to democracy was fixated on the mode of transition, and when concepts such as authoritarian legacy, authoritarian enclave, or the shadow of the past dominated, Wendy Hunter's 1997 book, Eroding Military Influence in Brazil, went against the grain. In a direct attack on institutionalist approaches that emphasized the resiliency of military prerogatives in transitions from military regimes, Hunter argues that democracy itself would, over time, reduce the influence exerted by the armed forces. A solid theoretical orientation, rich casework, and insightful commentary on the dynamics behind the creation of civilian control all mark the book as a noteworthy contribution to the literature on democratic transitions, civil–military relations, and Latin American politics.

Abstract:

Purpose Transitions – as a focus of study – have been missing from information behaviour research. The purpose of this paper is to explore the topic of transitions – their characteristics and influences, the related concept of liminality and Transitions Theory – and what it can contribute to the field of information behaviour. This exploration includes the application of liminality and Transitions Theory to an empirical study of participants making the transition from doctoral student to early career academic. Design/methodology/approach In addition to an extended literature review, this paper reports on a qualitative study that used constructivist grounded theory methodology for data collection and analysis. Early career academics were followed for a five- to seven-month period and data were collected using interviews and “check-ins”. Transitions Theory and liminality were used to guide the analysis. Findings Three important findings were highlighted: the complicating effects of being in a liminal space on information behaviour; the changing information needs of those undergoing a transition; and the importance of comparison as a way of using information to understand new situations. A revised model of Transitions Theory (Meleis et al., 2000) is also proposed, to incorporate information behaviour. Originality/value This paper demonstrates that by examining information behaviour over longer periods of time and by making transitions a focus of research, new understandings and insight can be gained into what information individual needs, how they find, share and use that information. This research demonstrates that information behaviour research adds important elements to the study of transitions and, conversely, that transitions (and Transitions Theory) add important elements to the study of information behaviour.

Full text

Abstract:

The supercritical transitions are widely occurring. They include the supercritical transitions in the liquid-vapor system, ferromagnetic transitions, transitions in polymers, many transitions in liquid crystals, and some structural transitions. In the paper it is emphasized that the nature of the critical and supercritical transitions is the same – these are continuous fluctuation transitions. Above the critical temperature the system passes through a region of lowered stability, which leads to increase of fluctuations of energy and external parameters of the system. From the point of view of thermodynamic stability this indicates the existence of a continuous supercritical transition between supercritical mesophases. Knowing the basic stability characteristics of a system, we derive the equation of these mesophase transitions. Depending on a thermal equation type, we can get one or several such equations, which may not coincide. This approves the fact that a supercritical transition occurs in a certain interval of thermodynamic forces. In the paper the relations between the critical exponents of thermodynamic parameters of the system are obtained and the conditions of continuous conjugation of the lowered stability line to subcritical coexistence line are investigated. The results are applied to the Curie–Weiss and van der Waals models: we obtain the quasi-spinodal equation for these systems and analyze the critical and supercritical behavior of the stability characteristics.

Full text

Abstract:

Although Eurocentric scholars theorize the world in terms of Western evolutionary progress rather than de-evolutionary retrogression, this paper takes a different perspective. Forced to transition away from their tangible and intangible heritages, from their families and marriages, cultures, societies, polities, and economies in ways that legitimized imperial claims to res nullius (unowned resources) and terra nullius (empty land), some indigenous people wittingly and unwittingly increasingly devolved their heritages to the colonialists that benefited from the African transitions. The point here is that unlike “Bushmen” and those that practiced transhumance, contemporary Africans are forced to transition, to change and to transform away from owning and controlling their tangible and intangible resources, including land, culture, laws, religions, polities, economies, livestock, families, marriages, and so on. Whereas “Bushmen” and transhumance migrated and transitioned while retaining ownership and control over their land, forests, livestock, and so on, contemporary Africans are forced to transition in ways that divorce them from their families, marriages, cultures, religions, polities, and from ownership of their material resources. Because Eurocentric forms of transition put African institutions and resources on the chopping boards, we argue that this kind of transition is cannibalistic. Made to believe that transition is easier to accomplish without the supposed burden of repossessing ownership and control over one’s resources, Africans are witnessed as disinherited and wandering around the world arguably in ways that even precolonial “Bushmen” and transhumance pastoralists would not envy. There is no justice in “transitional justice” that transitions indigenous people from their heritages.

Abstract:

Requirements of the desired software product can be translated into state transition diagram or other UML diagrams. To verify the complete coverage of software requirements, the proposed Ant based approach generates non-repetitive transitions from the input state diagram. This approach has less redundant transitions and also gives uncovered transition in successive paths instead of giving whole redundant path again and again. The paper also contains a comparison between already existing approaches with respect to some parameters like coverage, redundancy, total number of transitions.

Abstract:

Transition detection is the necessary step in retrieval and investigation of videos on the basis of contents. Since last two decades, most of the researchers are involved in developing algorithms for detection of gradual transitions. However, the features of all gradual transitions are different and hence this issue still needs to be addressed precisely. After identifying this issue, an integrated shot boundary detection method is proposed in this paper. Wipe transition is the effect which is mostly used in the video making industries .Since there are different types of wipe transitions, it becomes very difficult to detect such transitions. Due to complexity in detection of wipes due to noise, object and camera motion earlier methods have less focus on this issue. In this paper an efficient wipe detection method is presented which gives better results even in the presence of object and camera movements.

Abstract:

In this paper I use discrete-time proportional hazards models of competing risks to assess the association between household transitions and housing transitions for individuals in the rental sector. Specifically, moves within the rental sector are treated as a competing risk with moves to homeownership. A series of longitudinal models indicates the differential role household transition serves in predicting each of these movement types. This research confirms the association between relative household stability, relative income level, and the move to homeownership. Conversely, homeownership remains unattainable for individuals with relatively low incomes, in relatively transient household types, and especially for minorities.

Finally, we calculate the emission of gravitational waves associated with deconfinement phase transitions, discuss the possibility of their detection, and how this would provide information about the equation of state of dense matter.

Abstract:

Areas of environmental transition, where ecological communities coincide, are sometimes termed ecotones. These regions often correspond with sharp environmental gradients. Ecotones occur at multiple spatial scales, ranging from transitions between biomes to local small-scale transitions. In recent years ecotones have received increasing scientific attention after being neglected for years, as studies historically often focused on distinct communities. However, it is still debatable whether these transitional regions are speciation and biodiversity hotspots that deserve special conservation interest or are actually areas that hold marginal populations that depend on other parts of the range for the maintenance of their biodiversity and therefore should not deserve primary investment. This paper discusses some of the recent advancements in our understanding of the role of ecotones in ecology, evolution, and conservation.

Abstract:

This paper develops a geographic understanding of urban energy transitions in sub-Saharan African towns and cities. In doing so this paper seeks to critically reflect on the value and limits of urban transitions analysis as a framework for understanding energy networks beyond the largely integrated systems across the Global North. We explore how these potentials and deficits can be addressed by examining promising developments across a series of debates in urban studies that can help sensitise this approach to energyscapes in the African context. By reviewing urban transitions analysis through these debates the paper offers four important contributions to expand existing ways of understanding energy transition. These include the particular urbanisation dynamics of African towns ands cities, the need to locate the urban across energy regimes, the agencies of various intermediaries and urban actors and the contested politics inherent in the governing of energy networks. In the conclusion we reflect on the specific directions that have emerged from the paper in relation to our contributions, offering a geographically informed framework that allows us to better examine the challenges and specificities of transition across these rapidly growing urban regions.

Abstract:

Purpose – The purpose of this paper is to share the lessons learnt during the implementation of a Peer Support Worker (PSW) pilot project within Child and Adolescent Mental Health Services (CAMHS). The project aimed to reduce the barriers experienced by young people and carers during the process of transition between child and Adult Mental Health Services (AMHS). Design/methodology/approach – The paper combines reflections of staff, PSWs and trainers in order to share the lessons that may be taken from this project. This includes a rough guide for those hoping to employ PSWs to support transitions. Findings – The PSWs provided the vehicle to support the process of transition by empowering young people and their carers to use their strengths to facilitate a hopeful and timely transition. Recommendations regarding support for peers, staff and the organisation during the process of training and employing peers are discussed. Research limitations/implications – The paper provides a purely reflective account of the pilot project. These reflections may provide guidance for others wishing to develop peer support positions within CAMHS so that an evidence base for the effectiveness of peer support within transitions may continue to grow. Originality/value – Rotherham Doncaster and South Humber NHS Foundation Trust are the first NHS Trust in the UK to employ PSWs specifically to support transitions between CAMHS and AMHS. This paper builds on the work of Oldknow et al. (2014) to highlight the first attempts to use peer support to support transitions.

Abstract:

The importance of A1203 materials in applications such as catalysis (γ-Al203) has brought about renewed interest both in the structures which form during the transition from γ- to α-Al203 and in the grain morphologies which accompany the transition. These transitions are especially important in the area of ceramic processing, as demonstrated by the recent reports. The structures of the transition aluminas, while still not completely understood, have been studied by several groups. The present paper reviews an on-going study of the transition from γ- to α-alumina where the emphasis is on the identifying the forms observed, and the morphology the grains adopt. Results from the initial parts of this study have previously been reported. The method of preparation determines the amounts and the forms of alumina present in the final sample.

Abstract:

AbstractWhilst much of the contemporary debate on regime change remains concentrated on transitions to and from democracy, this paper focuses on autocracy-to-autocracy transitions, a relatively understudied but particularly relevant phenomenon. Building on an updated typology of non-democratic regimes and through a qualitative case-by-case assessment, the present paper identifies 21 transitions from one dictatorship to another, out of 32 cases of autocratic breakdown during the 2000–15 period. Hence, after the fall of a dictatorship, the installation of a new authoritarian regime was almost twice as likely as democratization. Accordingly, the paper focuses on the 21 recorded autocracy-to-autocracy transitions and examines in which non-democratic regimes a transition from an autocracy to another is more likely to occur, which peculiar forms of authoritarian rule tend to be installed, and the specific ways in which the dismantling of the previous existing authoritarian rule is achieved.

Abstract:

Abstract Current metrics fail to adequately capture the temporal and spatial complexity of energy transitions in a sufficiently meaningful way and this limits their usefulness to inform effective climate and energy policy and management. In this paper we propose a cumulative integral of CO2 emissions intensity for electricity and heat use as a metric to monitor energy transition progress. We demonstrate its application using International Energy Agency data for each of the G20-member countries. Findings show that whilst most countries are far from the energy transition positions required to effectively mitigate climate change, there are some examples of countries that have made an effective transition that provide useful insights into how energy transitions might progress more extensively.

Abstract:

Experiments have shown that transitions occur between electron neutrino, muon neutrino, and tau neutrino flavors. Some experiments indicate the possible existence of a fourth neutrino known as the sterile neutrino. The question arises: do all neutrino flavors participate in transitions between flavors? These transitions are viewed as mass state transitions in parametrized relativistic dynamics (PRD). PRD frameworks have been developed for neutrino flavor transitions associated with the mixing of two mass states or the mixing of three mass states. This paper presents an extension of the framework to neutrino flavor transitions associated with the mixing of four mass states.

Abstract:

This paper considers a dynamic and adaptive trajectory generator for negotiating paths using S-curves. Applying constant jerk transitions between the constant acceleration and deceleration periods of the trajectory, the trajectory will optimally transition to the desired speed setting. Optimal is defined to be the minimum time to transition from the current speed to the set speed for the move segment when jerk and acceleration are limited. The S-curve equations will adapt to instantaneous changes in speed setting and path length. An integrated motion planner will determine allowable speeds and transitional profiles based on the remaining move distance.

Abstract:

Transition studies is a growing discipline for addressing sustainability challenges. Traditionally, its focus has been at the system level. However, addressing sustainability challenges also requires attending to the role of agents in sustainability transitions. This is the focus adopted in this paper. We review the literature on agency in sustainability transitions, based on 77 journal articles on sustainability transitions listed in Scopus from 2014 to 2018. We find that agency is increasingly explored in the sustainability transitions literature. Despite this growing interest, this body of knowledge remains scattered in regard to typologies or theoretical framings. Our review leads us to identify three recurring themes. One theme drew our attention in particular: the transition research community is divided into those who argue that agency is sufficiently embedded in the transition literature and those who oppose this argument. Going forward, the dynamics of individual-level agency, including behaviors and motivation, deserve further attention.

Abstract:

The level of violence seen during transitions from authoritarian to democratic rule varies substantially. Recently, Tunisia experienced an almost bloodless transition, while in Libya the attempt to oust the Gadhafi regime ended in a civil war. This paper looks at the dynamics of democratic transitions, and attempts to explain why some become extremely violent while others progress peacefully. Specifically, the paper looks at the potential role of international governmental organizations (IGOs) for constraining or altering the behavior of non-democratic regimes, thereby influencing regime transitions. It argues that, by alleviating commitment problems between the outgoing regime and the new elites, and by imposing sanctions that reduce an incumbent regime’s ability to reap the benefits of office, IGOs increase the likelihood of seeing a peaceful transition to democracy. However, the paper also argues that non-democratic leaders should anticipate this, and therefore that regimes that are members of highly interventionist IGOs should be less likely to liberalize at all. The paper finds evidence in favor of the proposition that IGOs increase the likelihood of a peaceful regime transition, and that non-democratic regimes that are members of highly interventionist IGOs anticipate being constrained by these organizations, and therefore are more reluctant to liberalize in the first place.

Abstract:

Improving the understanding of the politics of sustainable energy transitions has become a major focus for research. This paper builds on recent interest in institutionalist approaches to consider in some depth the agenda arising from a historical institutionalist perspective on such transitions. It is argued that historical institutionalism is a valuable complement to socio-technical systems approaches, offering tools for the explicit analysis of institutional dynamics that are present but implicit in the latter framework, opening up new questions and providing useful empirical material relevant for the study of the wider political contexts within which transitions are emerging. Deploying a number of core concepts including veto players, power, unintended consequences, and positive and negative feedback in a variety of ways, the paper explores research agendas in two broad areas: understanding diversity in transition outcomes in terms of the effects of different institutional arrangements, and the understanding of transitions in terms of institutional development and change. A range of issues are explored, including: the roles of electoral and political institutions, regulatory agencies, the creation of politically credible commitment to transition policies, power and incumbency, institutional systems and varieties of capitalism, sources of regime stability and instability, policy feedback effects, and types of gradual institutional change. The paper concludes with some observations on the potential and limitations of historical institutionalism, and briefly considers the question of whether there may be specific institutional configurations that would facilitate more rapid sustainable energy transitions.

Abstract:

Smooth transitions through the early years of education are recognised as pivotal to later personal and academic success. However, for children considered outside the mainstream, these transitions can provide extra challenge for them, their families and educators. This paper reveals the findings of two qualitative studies investigating early years’ transitions. The first study focused on the transition of children with disabilities into early childhood education and care (ECEC) centres; the second explored transition to school for emergent bilingual children. These studies highlight ‘strengths-based’ perspectives (Perry, Dockett, & Petriwskyj, 2013), wherein participants are understood as experts in their own lives bringing strengths as well as challenges to the new context. Despite the differences in participants, timing and methods, key themes were evident across the studies: parent perceptions of transition; educator attitudes; and home/centre or home/school relationships. These themes are significant to all educational transitions for children considered outside the mainstream.

Abstract:

In this paper we present results based on the project Old Guys Say Yes to Community. We interviewed 90 men in southern Portugal between 60 and 93 years of age. Our main aim was to understand how older men experienced their transitions from work to retirement. We clarify the concept of transition and the models that explain transitions in the life course perspective. There are a number of factors to consider during the processes of retirement. Also, not much is known about the role of education and learning during the transition process. We try to contribute to the field, reflecting on the learning processes that result from this transition. Our findings show that work is one of the most crucial dimensions to consider in transitions to retirement (despite the fact that we identify many others). But education and learning do have an immense impact on the lives of older adults, either negative or positive.

In this paper, we used a self-propelled particle model to study the transition between phases of collective behavior observed in animal aggregates. In these systems, transitions occur when individuals shift from one collective state to another. We investigated transitions induced by both the speed and the noise. Statistical quantities that characterize the phase transition driven by noise, such as order parameter, the Binder cumulant and the susceptibility were analyzed, and we used the finite-size scaling theory to estimate the critical exponent ratios [Formula: see text] and [Formula: see text].

Case study accounts synthesising semi-structured interviews with function and service use data from medical records were compared.FindingsThree types of care transitions were derived from the analysis: manageable, unstable and disrupted. Each type had distinguishing characteristics and older people could experience elements of all types across the system. Transition types varied according to personal and systemic factors.Originality/valueThis study identifies types of care transition experiences across acute, sub-acute and primary care from the perspective of older people and their carers. Understanding transition types and their features can assist health professionals to better target strategies within and across the system and improve patient experiences as a whole.

This paper presents novel designs of Ka band transitions between standard rectangular waveguide and substrate integrated waveguide (SIW). The proposed transitions can provide simultaneous field and impedance matching. The transition with a height-tapered waveguide exhibits outstanding low-loss performance over an ultra-wideband range (entire Ka-band). And the other one with Chebyshev transformers has a compact profile and low loss better than 2dB in a bandwidth of 11GHz at Ka band. The simulation and analysis of the transitions are carried out with Ansoft HFSS.

Abstract:

The electrostrictive properties above Tε max represented by the field-related and polarization-related M and Q coefficients have been measured for PbZr 1 - x Sn x O 3 single crystals with aniferroelectric phase transitions. The investigations presented in this paper have proved that the M11(T) and Q11(T) runs bring direct information of the pre-transitional effects connected with the co-existence of local polar objects with nonpolar matrix. Due to this co-existence, nonlinear Q11(T) dependence in the neighborhood of T C has been detected. Observed even in a wide temperature above T C , this co-existence is a natural feature of the material with ABO3 perovskite structure that undergoes structural transition to polar phase.

Abstract:

The need for an analytical method that one can apply manually to estimate dynamic impact forces on railway tracks that occur because of varying track stiffness or track profile initiated a study to develop an analytical method named as the Bezgin Method. The advancement of this method presented in this paper includes an extension of a set of equations developed and introduced by the first author earlier as the Bezgin Equations using the proposed method and development of a new equation. In addition to track stiffness taken into consideration in the equations introduced earlier, the Extended Bezgin Equations presented in this paper take into account bogie stiffness, wheel spring stiffness, Hertzian contact stiffness, and a factor for damping. The new equation takes into account the effect of vertical wheel acceleration as a train transitions to a stiffer structure or transitions along an ascending track profile. The paper unites and applies these equations to estimate wheel forces that develop along stiffness transition zones by considering an array of train speeds for an array of track stiffness ratios and representative values for track profile deviations along the transitions. Final section of the paper includes elaborate finite element analyses of structural track models that involve transitions of soil supported ballasted railway tracks with concrete based ballasted tracks along various transition lengths and compares their estimates for dynamic impact force factors with those estimated by the Extended Bezgin Equations. The paper concludes with a discussion of the potential uses, benefits, and the value of the Bezgin Method for railway engineering.

Abstract:

This paper assesses the work of Robert Brenner alongside the insights developed within social-reproduction feminism to reassess discussions on the origins of capitalism. The focus on the internal relation between social production and social reproduction allows social-reproduction feminism to theorise the construction of gendered capitalist social relations that previous accounts of the transition to capitalism have thus far been unable to provide. It argues that a revised political Marxism has the potential to set up a non-teleological and historically specific account of the origins of capitalism. This paper seeks to redress the theoretical shortcomings of political Marxism that allow it to fail to account for the differentiated yet internally related process involved in the constitution and reconstitution of gendered capitalist social relations. This critique contributes to a social-reproduction feminism project of exploring processes of social production and social reproduction in their historical development and contemporary particularities.

Abstract:

Abstract This paper focuses on the transition in the Dutch cutter fleet-targeting flatfish, from the conventional beam trawl to the pulse trawl fishing gear. In doing so, we explore the process of gear transition, presenting the challenges that fishers and policy-makers face. The pulse trawl technique represents a particularly controversial gear transition as it makes use of electricity, which has been banned by the European Union since 1988. However, it is seen by those developing it in the Netherlands as an important alternative fishing gear to the conventional beam trawl technique, which is becoming increasingly inefficient with rising fuel prices and well-documented impact on benthic habitats. By using a multi-level perspective on socio-technical transitions as the analytical framework, we explore the development of the pulse trawl and the interaction between different levels. We also discuss the influence of technology-push on its transition into practice and regulation. This paper demonstrates the importance of social dimensions in the adoption of new fishing gears and in doing so contributes to our knowledge on how technological transitions in fisheries can be managed.

Abstract:

Socio-technical transitions towards more sustainable modes of production and consumption are receiving increasing attention in the academic world and also from political and economic decision-makers. There is increasing demand for resource-efficient technologies and institutional innovations, particularly at the city level. However, it is widely unclear how processes of change evolve and develop and how they are embedded in different socio-spatial contexts. While numerous scholars have contributed to the vibrant research field around sustainability transitions, the geographical expertise largely has been ignored. The lack of knowledge about the role of spatial contexts, learning processes, and the co-evolution of technological, economical, and socio-political processes has been prominently addressed. Bridging approaches from Transition Studies and perspectives of Economic Geography, the paper presents conceptual ideas for an evolutionary and relational understanding of urban sustainability transitions. The paper introduces new perspectives on sustainability transitions towards a better understanding of socio-spatial contexts.

Abstract:

The recent wave of democratic transitions has stimulated scholarly interest in a previously undeveloped area of study: comparative presidentialism. Comparative presidentialism seeks to define variant types of presidentialism that have emerged from transition processes, to identify the conditions that shape institutional choice and to understand more clearly the causal relationship between institutional choice and democratic regime outcomes. Using the postcommunist transitions, this paper contributes to the emerging comparative presidentialism literature by suggesting a revision to the argument that presidentialism leads to failed democratic transitions. The paper focuses attention away from the institutional rules of the game and toward the actors who actually make the institutional choice. Three postcommunist cases, distinguished by their different regime outcomes, are compared: Russia, Uzbekistan, and Estonia.

Abstract:

Abstract. Latitudinal transitions from low to high Doppler spectral width in backscatter measured by the Super Dual Auroral Radar Network (SuperDARN) are now routinely used as proxies for the polar cap boundary (PCB) in the cusp-region ionosphere. In this paper we perform a statistical study of the nature of similar spectral width transitions at other magnetic local times (MLTs). This analysis illustrates that these latitudinal spectral width transitions exist at all magnetic local times, and that the latitude, gradient, and amplitude of the transitions vary systematically with MLT. In particular, the probability of a transition occurring at any latitude, identified independently in each MLT sector, is continuous with MLT from the cusp, through the morning sector, to the nightside. This suggests that the transition represents the PCB, as this is known to be what it represents in the cusp region. However, the picture in the afternoon sector (12:00-18:00 MLT) is more complex with no clearly preferred transition latitudes. Key words.
