Abstract:
The article presents the set of data related to development of museum illumination control standards. The main goal of the review is to demonstrate the balance between illumination adjustment as a means to improve preservation of museum exhibits and adjustment as a means to improve presentation of exhibits to visitors. Such review became necessary due to intensification of activities for development of museum illumination regulations since 2018. As part of these activities, the specialists of two leading organisations – light engineers of the Russian Lighting Research Institute named after S.I. Vavilov (VNISI) and the museum and restoration community of the State Research Institute for Restoration – fulfilled a contract for analysis of museum practice in the sphere of museum illumination. The results of the studies under the contract were reviewed and approved during an extended meeting of the museum illumination commission of the Scientific and Technical Council of the Lighting Industry in the Russian Federation (STC “Svetotekhnika”) with participation of representatives of the museum community. The results of this work were also discussed at a meeting of the scientific council of GosNIIR. In 2020, specialists of VNISI developed four regulations of LED illumination for museums after fulfilling the contract. The article presents a brief description of the potential of these documents for improvement of development of LED museum illumination. It demonstrates limited applicability of the developed standards to actual needs of museums and the mistakes made by the developers, which pose risks for preservation of museum exhibits if these standards are used in practice. The author proposes the ways of further development and improvement of the regulatory framework of museum illumination. These ways and the programme of regulation development were discussed and approved at the meeting of the scientific council of GosNIIR.

Abstract:
It has been proposed that general lighting practice should switch from specifying indoor illumination standards in terms of task illuminance to ambient illumination specified in terms of mean room surface exitance. The reasons for this proposal are reexamined and the energy implications are assessed. To enable comparison of equivalent levels of illumination, it was first necessary to establish mean room surface exitance levels that equate to task illuminance levels as being typical for similar applications. A simulation was developed using AGi32 lighting design software to determine lighting power density levels for providing equivalent illumination by three luminaire luminous flux distributions for three room shapes with three surface reflectance combinations. As anticipated, the downlight distribution was found to be the most efficient way of satisfying task illuminance criteria, but also it was found that uplighting achieves similar lighting power density levels for the equivalent mean room surface exitance criteria if room surface reflectances are reasonably high, indicating that the switch could be made without departing from the lighting power density limiting values currently proposed for efficient use of lighting energy. However, to base lighting standards on low lighting power density levels would have the effect of severely restricting options in lighting practice. Accordingly, a range of lighting power density levels is proposed for lighting standards that would eliminate inefficient use of lighting energy while permitting reasonable levels of design flexibility in lighting practice.

Abstract:
Face recognition programs have many practical usages in various fields, such as security or entertainment. Existing recognition algorithms must deal with various real life problems – mainly with illumination. In practice, illumination normalization models are often used only for Small-scale futures extraction, ignoring Large-scale features. In this article, new and more direct approach to this problem is offered, used algorithms and test results are given.

Abstract:
Light-emitting diodes (LEDs) have been widely used in road lighting. This study investigates the optical design of a high-mast luminaire based on four chips-on-board LED light source modules and applies it to road lighting. The model of the high-mast luminaire is built with Solidworks, and then the optical simulations are analysed by Tracepro and Dialux. We also make a physical prototype of the high-mast luminaire to test its performance in practice. The illuminance distribution of the test area is nearly rectangular. The interior of the rectangle forms a smaller highlighted rectangular illumination area with uniform illumination. The outer edges of the rectangular illumination area will overlap the outer edges of the illumination area of other high-mast luminaires. The desired illuminance distribution and the uniform illumination can be obtained. Both the simulations and the experimental results meet the requirements of road lighting standards and the high-mast lamp can even achieve a better optical performance.

Abstract:
Attending closely to the implicit kineticism of Picabia's 1924 “Instantaneist Manifesto” and the musicalist aesthetic of his art, Annette Michelson considers the artist's interest in time and moving images, arguing that temporalization is the key impulse in his practice regardless of medium. This dedication to temporalization, the author claims, manifests not only as a fetishization of mobility and travel but more critically as the stimulus for interrelations between dance, cinema, painting, and poetry.

Abstract:
Near-infrared photoimmunotherapy (NIR-PIT) is a new cancer therapy that uses NIR light and conjugates of a tumor-targeting monoclonal antibody and phthalocyanine dye. In clinical practice, frontal and cylindrical diffusers are the only options for NIR illumination. However, illumination in a narrow space is technically difficult with such diffusers. Therefore, we evaluated a lateral illumination system using a lateral emitting laser (LEL) fiber. The LEL fiber illuminated a certain area in a lateral direction. NIR-PIT with an LEL fiber reduced luciferase activity in a light-dose-dependent manner in A431-GFP-luc cells in vitro and significantly suppressed tumor proliferation in a xenograft mouse model. To evaluate the usefulness of the LEL fiber in the illumination of a narrow space, a tumor was illuminated from the inside of a cylinder, mimicking a narrow space, and the fluorescence intensity in the tumor was monitored. In the frontal diffuser, NIR light was unevenly delivered and little light reached a distal tumor area from the illuminated side. By contrast, the LEL fiber allowed a uniform illumination of the entire tumor, and a loss of fluorescence was observed even in distal areas. These findings suggested that the LEL fiber can be used for NIR-PIT and is suitable for NIR light illumination in a narrow space.

Full text
Abstract:
This thesis represents a practice-led enquiry into contemporary illustration from a UK perspective. This thesis argues for illustration to be recognised as an inductive practice-led research process, within both education and developing criticism. The methods and methodological discussion to support this are derived from the practical aspect of the enquiry. The inductive approach outlined through the methods chapter focuses on the benefits of removing the known outcome from projects, and of illustrators maintaining their own practice alongside commissioned work. The discussion of methods proposes that the commissioned strand of illustration adopts research in illustration as research for illustration. The discussion of performative forms adopted within illustration contributes to the discourse surrounding practice-led research outcomes, in particular Brad Haseman’s performative paradigm for creative arts research. The methodological approach is proposed as a supplementary strand of teaching, which equips illustrators with long-term skills to generate their own projects and employment. These enable illustrators to be flexible and able to adapt to economic and technological changes to industry practice. The thesis examines research processes within illustration which are transferable to different contexts. These include the increase in digital screens and their time-based communications, and the development of three-dimensional objects and environments within the field. The practical work undertaken employed these processes and generated a contribution to the growing discourse surrounding contemporary illustration in the UK. Illustration suffers from a lack of published analysis and as a result its critical discourse is limited. Therefore this study bases its argument upon themes identified within existing illustration commentary, the work of key practitioners, and my studio practice. The focus of research undertaken is mainly on self-initiated projects, but includes commissions where the outcome is not prescribed from the outset. Conversations with Matthew Richardson, Luise Vormittag, Steve Braund, Andrzej Klimowski and Henrik Drescher provide supplementary primary research. The outcome is a contribution to the development of a critical framework derived from practice, which acknowledges the shortcomings of existing frameworks available. The thesis proposes that the concept of time be adopted as a key characteristic of illustration, the discussion of which references Henri Bergson, comics and artist’s books. The utility of time lies in its productive application to both the production and analysis of work. Illustration’s unique negotiation of time through spatial manifestations is used to situate the field in relation to key shifts within culture such as Fredric Jameson’s postmodernism and Nicolas Bourriaud’s altermodernism. The thesis outlines the diversity of temporal achievements within illustration in this regard, and calls for greater recognition of illustration practice and discourse within such discussions of the time we live in.

Abstract:
During the Middle Ages, the Christian church primarily employed the visual arts to showcase and communicate theology. Yet within the realms of today’s audio-visual media, the popularity of spoken-word short films indicates a preference within the Christian community for didactic speech over traditional visual symbology. In examining ways in which the primacy of the visual spectacle might be reinstated into modern screenbased forms of theological communication, this doctoral research identifies an enduring and powerful element in the underpinning presence of illumination. Understood in concrete and abstract modes, illumination can be both a physical process of lighting, as well as spiritual or mental knowledge. This multimodality allows it to be an effective allegorical device for expressing abstract theological concepts through concrete visual forms, exemplified in stained-glass windows, magic lantern shows and, as my research proposes, the recent mediums of film and the digital video screen. My research revises the practice of illumination for visual theology in short film. Using a conceptual framework, it identifies key properties of illumination, alongside practical filmmaking equivalents and demonstrations in the form of my three short films. Early cultural and historical studies in religious practice and Platonic philosophy reveal illumination’s allegorical applications, and provide models of comparison by which contemporary methods can be determined. With reference to relevant theories from Roland Barthes, Paul Schrader and André Bazin, my cultural studies indicate that illumination essentially facilitates the mediation process between binaries, including the progression from darkness to light, ignorance to knowledge, concealment to revelation, man to God, confinement to liberation, and death to life. Content, discourse and semiotic analyses were then applied to select short and feature films to identify contemporary equivalents of illumination in faith-based and secular cinema. The surveyed works include the films of Rob Bell, Francis Chan and Robert Bresson, as well as examples from formalist film theory and cinematic realism. Many of the illumination techniques detailed in this body of work appear as specific camera movements, mis-en-scène, symbolic lighting, film editing and reflective narrative pacing. Yet despite illumination being physically essential for film production, my cultural research would suggest that it operates in deeper systems, such as the progression of narrative from concealment to revelation, as from darkness to light. Along with my written research, the practical component of this investigation takes the form of documented optical experiments, and provides a method of assessing how realworld applications of illumination might metaphorically correlate with theological concepts and principles. The findings from both cultural and action research methods informed the production of my three short films: Negative Space (2015), Reflect (2016) and Pierced (2017). Each film functions as a practice-based research output and allows key illumination techniques to be demonstrated, tested and evaluated, consequently providing data for further inquiries. Placing primacy on real-world visual phenomena rather than the spoken word offers audiences a visual narrative that is arguably less didactic and more subjective. My research would suggest that a multimodal application of illumination can be instrumental in reinstating the spectacle in contemporary visual theology.<br>Thesis (PhD Doctorate)<br>Doctor of Philosophy (PhD)<br>Queensland College of Art<br>Arts, Education and Law<br>No Full Text

Abstract:
Enrique Granados, Frank Marshall, and Alicia de Larrocha are the chief exponents of a school of piano playing characterized by special attention to details of pedalling, voicing, and refined piano sonority. Granados and Marshall dedicated the major part of their efforts in the field to the pedagogy of these principles. Their work led to the establishment of the Granados Academy in Barcelona, a keyboard conservatory which operates today under the name of the Frank Marshall Academy. Both Granados and Marshall have left published method books detailing their pedagogy of pedalling and tone production. Granados' book, Metodo Teorico Practico para el Uso de los Pedales del Piano (Theoretical and Practical Method for the Use of the Piano Pedals) is presently out of print and available in a photostatic version from the publisher. Marshall's works, Estudio Practico sobre los Pedales del Piano (Practical Study of the Piano Pedals) and La Sonoridad del Piano (Piano Sonority) continue to be used at the Marshall Academy and are available from Spanish publishing houses. This study brings information contained in these three method books to the forefront and demonstrates its relevance to the performance of the music of Granados, specifically the Escenas Romanticas. Alicia de Larrocha, Marshall's best known pupil, currently holds the directorship of the Marshall Academy, and as such, is perhaps the best living authority on this entire line of pianistic and pedagogical thought. An interview conducted with Madame de Larrocha in April of 1983 adds detail and provides valuable perspective about the present use and relevance of these materials and concepts.

Abstract:
In the last decades of the eighteenth century, urban lives were touched by a series of innovations in the technology and aesthetics of illumination. Unfamiliar combinations of new fuel sources and auxiliary equipment (for example, curtains, blinds, glass, mirrors and lampshades) meant that cities looked and felt different during both the day and the night. The spheres of elite, popular, public and private culture explored, exploited and were fascinated by the cultural value of light. Through four case studies in the aesthetics of urban illumination, my thesis demonstrates how the acquisition of skills for the manipulation of transparent and reflective surfaces were crucial when negotiating a balance between self-expression and standards of taste, morality, gender and class. Rather than relying upon canonical examples of the period’s fascination with light, such as the high Romantic idealization of nature’s sunrises and sunsets, my thesis investigates more everyday encounters with light in the built environment: the fashionably genteel pastime of transparent painting; the gendering of light to design both domestic interiors and female identity; the appropriation of patrician top-lighting for public buildings of education and exhibition; and the popularity of illuminated spectacles in commercial pleasure gardens. I argue that these new possibilities of lighting temporarily enabled new possibilities of subjectivity. My historical phenomenology suggests that the formation of perception between 1780 and 1840 was actively directed towards changes in the world through a finely-attuned consciousness of light.

Full text
Abstract:
The initial focus of this thesis is on mentors' professional knowledge base, and subsequently on the pedagogical strategies employed by mentors and their use, in so far as it occurs, of adult learning theories, which have been said to form the dominant conceptual framework for mentoring (Hansford et al., 2003: 10). These issues are considered important as, despite acknowledgement by the DfES in 2001 as to the relevance of theory in mentor training, in practice mentor training is often limited to familiarisation with government and Partnership requirements in order for them to undertake the assessment of student teachers. Consequently very little attention is given to learning theories within mentor training. Whilst connections between mentoring and learning theories exist in literature my research highlights that there is a potential dichotomy between the literature and practice of mentoring. It therefore considers the extent to which adult learning theories are actually used in current mentoring practice. In addition my research also looks at the way mentor teachers' pedagogic strategies are shaped by the context and purposes they are working within, and the role ascribed to them. My research is based upon an in depth Case Study of 20 mentors from one HEI Partnership. It utilises qualitative method tools, with the primary tools being observations and semi-structured interviews. These tools assisted in progressively developing my research questions and conclusions as part of an inductive process. The results of my study show that the practice of mentors is largely influenced by their prior experience, primarily as teachers but also as student teachers; they see theory as having little influence on their practice. In addition my study indicates that few mentors are aware of learning theories or their principles. Nonetheless it indicates that the practice of most mentors includes the application of the principles of a number of adult learning theories. My research concludes that mentors use some of these principles through the development of their own personal construct theories, which in turn largely relies upon their prior experience, and through the framework provided by the HEI Partnership.

Abstract:
Vol. 1 This volume presents research into educational approaches for supporting young people at secondary transfer. The volume consists of a critical literature review and an empirical study, supplemented with an introductory chapter and concluding commentary. The review explores a 'continuity vs discontinuity' debate and examines previous research into the 'Primary Ethos' approach for maintaining continuity at secondary transfer. The review reveals a clear need for further Primary Ethos evaluations which look beyond impact, and which seek to elicit the views of the pupils and other key stakeholders. The empirical study reports on an illuminative process evaluation of a West Midland secondary school's Year 7 ‘Foundation Group’ initiative for low attaining pupils. With the evaluation’s primary purpose being to inform initiative development and organisational learning, the RADIO model (Knight and Timmins, 1995) was used. Following the identification of 5 collaboratively negotiated process questions, semi-structured interviews were conducted with pupils, staff and the Head teacher. Data analysis resulted in the identification of 'supportive factor' themes, areas for development, and issues pertinent to the school. The researcher concludes by suggesting that the application of an attachment theory perspective may be useful in providing a framework for future exploration of Primary Ethos initiatives. Vol. 2 This volume presents five independent ‘Professional Practice Reports’ (PPRs) which reflect work undertaken by a Trainee Educational Psychologist for the purposes of an Applied Educational and Child Psychology Doctoral training programme with the University of Birmingham (2006-2009). The first paper, 'An account of a Trainee Educational Psychologist’s involvement in a planned change process in an organisation' (Chapter 2), describes how a primary school Head teacher and Special Educational Needs Coordinator (SENCO) were supported with addressing the emotional and psychological implications of an impending change process. The second paper, 'Working with a complex emotion in children and young people: a critique of ‘Anger Management’' (Chapter 3), reflects upon the theoretical perspectives relating to anger and critiques the most common approach to dealing with anger in children and young people: Cognitive Behavioural Anger Management. The third paper, 'A critique of the issues relating to the implementation of a Multi-Agency Social Communication Difficulties (SCD) Assessment Protocol' (Chapter 4), critiques some of the issues surrounding the implementation of a new Multi-Agency Social-Communication Difficulties protocol for primary aged pupils within a West Midlands Local Authority. The fourth paper, 'Reflections on the work of an Educational Psychology Service’s Critical Incident Response Team (CIRT)’ (Chapter 5), reflects on the work of the CIRT in relation to the literature and research base on critical incident response, crisis intervention and trauma work with schools. Finally, the fifth paper, 'Fostering Inclusion through Circles and Strengths (FITOS): A critique of the process issues relating to the design, implementation and evaluation of a longitudinal pilot project in a primary school' (Chapter 6), critiques the process issues relating to the design, implementation and evaluation of an intervention (FITOS) specifically tailored to address a primary school’s concerns regarding a lack of empathy amongst pupils for pupils with special educational needs. In order to draw the volume together the five papers are supplemented with an introductory chapter (Chapter 1) which provides the reader with contextual information, reflects on how the work has contributed to the author's developing role as an Applied Educational Psychologist and comments on the actual or potential worth of the PPRs in contributing to the knowledge base and practice of the Educational Psychology profession.

Abstract:
This edited volume provides a multifaceted investigation of the dynamic interrelations between visual arts and urbanization in contemporary Mainland China with a focus on unseen representations and urban interventions brought about by the transformations of the urban space and the various problems associated with it. Through a wide range of illuminating case studies, the authors demonstrate how innovative artistic and creative practices initiated by various stakeholders not only raise critical awareness on socio-political issues of Chinese urbanization but also actively reshape the urban living spaces. The formation of new collaborations, agencies, aesthetics and cultural production sites facilitate diverse forms of cultural activism as they challenge the dominant ways of interpreting social changes and encourage civic participation in the production of alternative meanings in and of the city. Their significance lies in their potential to question current values and power structures as well as to foster new subjectivities for disparate individuals and social groups.

Abstract:
AbstractSeismic interferometry (SI) can be used to reconstruct a pseudo-acquisition from response of a passive source, while the reconstructed data can be used to recover a portion of the model space that is different from that recovered by the inversion of original measurements. The SI by crosscorrelation requiring the seismic wave field to be evenly distributed, which limits the scope of application of this method. SI by multi-dimensional deconvolution (MDD) broken through the limitation that the wave field must be evenly distributed, but there are still some limitations in some special practices. Interferometric point-spread function (PSF), like the correlation function, is a necessary condition of the MDD method, but in some practices it cannot be derived from the field data. A new MDD method is proposed in this paper that free from PSF, and theoretically proved that it is equivalent to usual MDD. We demonstrate the effectiveness of this method with two numerical examples of one-sided illumination, and the source blurring phenomenon in the results of SI by crosscorrelation is effectively eliminated. The first numerical example is far-field one-side illumination, which can also be treated with the usual MDD, and the comparison of the results shows that the two MDD methods are equally effective. The second example is the near-field one-side illumination, and only the MDD method proposed in this paper can be used because the PSF cannot be obtained.

Full text
Abstract:
Understanding irradiance/illuminance is important in many fields including machine vision, image processing, and computer graphics. In this paper we present a general method for calculating the illuminance at a point due to an arbitrary spatial arrangement of uniform, diffusely-emitting sources whose surfaces comprise arbitrarily-shaped planar polygons. The calculation is based on a hemisphere projection method that had been considered suitable for obtaining qualitative, but not quantitative, understanding.1 By approximating sources as planar polygons, exact solution is achieved. This approximation is not restrictive in practice because surfaces can be tesselated into polygons that are arbitrary with respect to number and shape. The calculation handles cases that can be difficult using other methods: sources that occlude each other and points that lie on edges where sources meet. The hemisphere projection method has use in designing illumination systems for machine vision, in calculating illumination for model-based image processing algorithms such as "shape-from-shading," and in calculating radiosity form factors for computer graphic simulation of scenes with interreflection between objects. We also present the conditions under which the method can be extended to planar polygon sources with non-uniform, non-Lambertian emission.

Abstract:
Abstract This paper delves into the challenges encountered during the transition from traditional lighting to energy efficient LED lights during facility lighting system upgrades. An issue of particular concern arises when these lights are replaced on a one-to-one basis. This practice often leads to excessive brightness, resulting in problems such as employee discomfort and light pollution. To address this challenge, the paper proposes a systematic approach based on the constant illumination principle. This method aims to accurately determine the optimal quantity of lights needed during the upgrade process. To illustrate the efficacy of the proposed approach, two lighting system redesign scenarios are present: Plan A with T8 lights and Plan B with LED lights. These scenarios highlight the importance of employing the constant illumination approach in facility lighting redesign projects. By adopting this approach, facilities can effectively embrace LED technology and subsequently, creating a comfortable work environment and promoting environmental sustainability.

Full text
Abstract:
The number of emitted photons that can be obtained from a fluorophore increases with the incident light intensity and the duration of illumination. However, saturation of the absorption transition and photodestruction place natural limits on the ultimate signal-to-noise ratio that can be obtained. Equations have been derived to describe the fluorescence-to-background-noise ratio in the presence of saturating light intensities and photodestruction.1 The fluorescence lifetime and the photodestruction quantum yield are the key parameters that determine the optimum light intensity and exposure time. To test this theory we have performed single molecule detection of phycoerythrin (PE). The laser power was selected to give a mean time between absorptions approximately equal to the fluorescence decay time. The transit time was selected to be nearly equal to the photodestruction time of ~600 μs. Under these conditions the photon count distribution function, the photon count autocorrelation function, and the concentration dependence clearly show that we are detecting bursts of fluorescence from individual fluorophores as they pass through the laser beam. A hard-wired version of this single-molecule detection system was used to measure the concentration of PE down to 10-15 M.2 This single-molecule counter is three orders-of-magnitude more sensitive than conventional fluorescence detection systems. The approach presented here should be useful in the optimization of fluorescence-detected DNA sequencing gels and in HPLC and capillary electrophoresis detectors.

Abstract:
Concept-based teaching and learning grounded on a mechanical paradigm has dominated western education tradition since the first industrial revolution. This type of educational tradition is characterised, among other things, by its reductionist and linear mindset that has led to siloed and disconnected knowledge generation. Yet the 21st Century demands us to rethink the traditional roles of the learner, the teacher and the learning environment. Climate change and wicked socio-ecological problems and challenges require a new ‘tradition’ to emerge, dominate and respond to our societal and planetary crisis. Integrated, multidisciplinary and transversal knowledge generation, dissemination and transfer, grounded on a strong critical ethics and philosophical exploration of new alternative educational paradigms, is paramount if we aim to respond accordingly to calls to create a better future today. Today’s 4th industrial revolution fusing Artificial Intelligence (AI) with the Internet of Things (IoT), genetic engineering, quantum mechanics and philosophy, and more is blurring the boundaries between the physical, digital, and biological worlds. This brings along the emergence of new understandings of the nature of human experience, and questions about how to design for it. In this scenario, education must become multidisciplinary again, where new epistemologies are to be the reflection of humanity’s process of change and transformation, while reconnecting with old and ancient knowledge and ways of doing. In the past, knowledge was considered a ‘unity’ whole acquired through journeys in people’s life, from where individuals learn by doing and experiencing every aspect of knowledge. One positive side-effect of embracing a unity view of knowledge today is that we can now make accessible non-western concepts, again, with emphasis on qualitative, subjective, emotional, embodied, ceremonial and spiritual views of knowledge generation and practice. How can we teach such concepts and views within a traditional and reductionist educational western system based on concept-based and siloed education? We cannot. Some knowledge, concepts and notions (known as ‘Qualia’ in the literature) can only be acquired through bodily lived and direct experiences. Today’s digital immersive technology can make it easier to integrate and consume knowledge through digital visualisation and self-led user experiences. New media can afford to provide learners a good foundation on many different disciplines, which normally would take years to achieve based on traditional pedagogy. Experience-based mediums like virtual reality (VR), if used in a non-concept based way, can bridge the knowledge gap existing created by qualia subjects in western societies. Here we argue that the epistemology coming from the Santiago school of cognition, with notions such as embodiment, embodied cognition and enaction, can inform and guide the development of an experience-based type of immersive learning design based on an enactive, self-led user experience. We propose that immersive learning experience design ought to focus first and foremost on ethics and critical philosophy, followed by embodied design for experience-based self-driven illumination. In this presentation we review the conceptual background leading to some examples of current experienced-based learning and self-illumination design exploration in immersive learning design, informed by the epistemology coming from the Santiago school of cognition.

Abstract:
This paper explores the ideological use and limited implementation of federalism in East Central Europe from 1831 to 1939, a region shaped by diverse national identities and the dominance of imperial powers. Federalism, widely promoted as a potential solution for unifying multiethnic societies under a shared political framework, primarily served as a rhetorical device rather than a practical model for governance. National movements and emerging states leveraged federalist ideas as tools to legitimize territorial claims, secure political authority, and establish cultural autonomy from imperial structures. However, the paper argues that national leaders consistently subordinated federalist principles to the pragmatic demands of nation-building, which prioritized ethnic and linguistic homogeneity. Despite federalism’s appeal as an inclusive model, its adaptation in East Central Europe was constrained by nationalist agendas, anti-imperial sentiments, and the instrumentalization of ideology for geopolitical maneuvering. This study highlights how federalist discourse in East Central Europe evolved from a utopian concept into an element of Realpolitik,illuminating broader tensions between ideology and practical governance in the region's history.

Abstract:
Water is central for a variety of livelihoods, development, economic growth, and food production. It is also very important in the large deltas of South and Southeast Asia. Yet, water is turning into a scare resource and global climate change is making its availability more unpredictable. Commercial interests and infrastructure development are also competing for water resources, sometimes at the expense of local smallholders. This report, which is a desk study combined with stakeholder interviews, aims to map out the issues and the previously unknown challenges to efficient water and land management for poverty alleviation and food security. It also serves as a basis for an empirical case study on the same topic. The report illuminates the political economy of land-water resources in the floodplains around the Tonle Sap Lake which constitutes the upper part of the Mekong River Delta and shares seasonal fluctuations and livelihood patterns. The report identifies key challenges for land-water integrity and multi-functionality in food security, nutrition and income impacts for different local producers. The versatile delta landscape and its livelihoods are a complex ecosystem; the driving factors include seasonal water flow variations, the construction of upper Mekong dams, climate change, and the minimal regulations of local resource governance. This evidently makes the governance challenge both immense and urgent. This report maps out opportunities from national to local levels for promoting more systematic, productive and inclusive land-water management. The roles of formal and informal actors within political spaces, their influence on policy and practice, and opportunities to influence these actors are of particular interest. In pursuing the above, the report applies a political economy approach, where the role of the state, its policies and resource allocation are in focus. This also includes the presence of politically and commercially vested interests and how civil society is involved in the general strife for food security and poverty alleviation. The political economy approach constitutes a holistic analysis of how a society is governed and who possesses and utilises which power in order to pursue their interests. At the core of the political economy approach is therefore the illumination of power (and powerlessness) through analysis of actors or a group of actors and their particular interests. The empirical realms in this report focus on contemporary resource management, its institutions and actors. The conclusions are as follows: The conclusions are as follows:The policies and legal frameworks are tentatively progressive, but still sectoral and sometimes fragmented. Institutional structures and agency interests in horizontal coordination and vertical implementation are considerably weaker than the laws and policies themselves. While concerned ministries have achieved a lot, they have not managed to effectively collaborate and work across sectors and ministries. They continue to treat landscapes in a segmented manner. Many policies fall short because there are a lack of adequate resources and local incentives to implement and follow-up on the ground. To systematically monitor the implementation of policies, studying their true weaknesses, feeding back to the concerned ministries and amending the policies according to their existing weaknesses, would further the efficacy of the system. The decentralisation reform programme at the sub-national level is one of the most promising governance reforms in post-war Cambodia. However, in its current version, it is not sufficient, because the scale of the problems at stake are typically greater than the commune jurisdiction. To complete the halfway reform of a “unified administration” at the district level, integrating agriculture, environment and water mandates may be the most important reform for the long-term future. This is a hypothetical scenario since the commune councils may not be as accountable to their local constituency as they were pre-2017. Overall, increased agricultural output, green revolution, mechanisation, and efficien market access are favoured in many policies and plans. Yet, fisheries, especially small- scale ones, are partially neglected in spite of the huge value, poverty alleviation abilities, and nutritional quality. The policy recommendations include: The national government system would benefit from an establishment of mandatory cross-ministerial meetings on a regular basis, facilitated by existing/new coordination structures leading to monitorable cross-sector and cross-agency actions towards more integrated water and land management. A systematic empirical monitoring of the rollout of policies would be very valuable since our analysis revealed that the weakest links in the policy work are the implementation, the upholding of the quality of interventions, and the safeguarding of the sustainability of already established policies. To further support the IWRM implementation, a planning process based on hydrological units (basins and sub-basins), resource inventories, development priorities for key social indicators (e.g., poverty, nutrition and gender), and arising trade-offs needs to be established. The recent decision to integrate water, agriculture and environment at the district level needs to be given full support, bringing in fisheries to the mandate. The rules for il/legal fisheries need to be clarified and the absence of efficient monitoring of fishing practices needs to be addressed. The government has recently promoted a partnership between public, private and farmer agents to enhance agricultural production and productivity for better food security. To push this further is a worthwhile opportunity.
