Innovation Ecosystems in the Context of Economic Development: A case study of Kraków, Poland
Creators: name: Baumane-Vītoliņa, Ilona

Publisher: name: Studies of Transition States and Societies
Year: 2020
Subjects: innovation ecosystem; technology; economic development; Poland; start-ups; small and medium size enterprises

description: The aim of this article is to provide a comprehensive overview of the innovation ecosystem, which remains a fragmented concept, and to analyse its role in the economic development of states. The objective is achieved by first, drawing on the existing literature and theoretical framework that concerns innovation ecosystems, and by subsequently analysing the nexus between these entities and the economic development of states. The main contribution this paper makes to scholarly debate on innovation ecosystems is in attempting to link theoretical assessments with empirical observations. By drawing on the case study of the innovation landscape in Kraków, Poland, this paper offers a first-hand insight into the role of local actors and mechanisms determining the performance of the ecosystem based on primary research. As such, the study attempts to review specific stages of innovation development and the unique role of start-ups and SMEs within the ecosystem. By crossing through historical, economic and social contexts, the study embarks on a multidisciplinary as well as “causes-of-effects” approach. The different roots of the Polish innovation ecosystem are discussed, yet not failing to address the future prospects for innovation in the country. Finally, the study attempts to structure Poland’s start-up experience as a guide by discerning the actors and mechanisms that drive a healthy ecosystem. In such a context, the Polish experience can be informative for CEE countries where start-up ecosystems exist at the nascent stage.

description: We present the results of DFT calculations of free energy profiles along the reaction pathways starting from 50% coverage of MoS2 M-edge and 100% coverage of S-edge by sulfur, and leading to 37% coverage, i.e. creation of anionic vacancies, upon reduction by dihydrogen and production of H2S. Significant entropic and enthalpic corrections to electronic energies are deduced from the sets of normal modes vibration frequencies computed for all stationary and transition states. On that basis, we revisit and discuss the surface phase diagrams for M- and S- edges as a function of temperature, H2 partial pressure and H2S/H2 molar ratio, with respect to ranges of conditions relevant to industrial hydrotreating operations. We show that in such conditions, anionic vacancies on the M-edge, and surface SH groups on the M- and S- edges, may coexist at equilibrium. Moderate activation barriers connect stationary states along all paths explored.
Changing Patronage and Informality Configurations in Ukraine: From the Shop floor Upwards

description: This article examines hegemonic norms of political and moral economy in Ukraine today acting at the level of the workplace. My research is based on fieldwork I conducted in a large industrial city in the east of Ukraine from January to June 2019. Using the general Gramsci-inspired theoretical framework and the insights of Hillel Ticktin, Simon Clarke and Michael Burawoy regarding Soviet and post-Soviet factory regimes, I analyse differences between the life-worlds of workers, relating them to the structurally different context in which they find themselves. All enterprises feature path-dependent informal bargaining and underinvestment as cornerstones of their factory regimes. However, they differ in the ways in which these traits combine in practice. These configurations, in turn, elicit different strategies and attitudes from the workers, each of them more typical at one enterprise than at others: an archaic manufactory attitude at a new window factory, exit in mines torn between owners, voice at the foreign-owned metalworking factory, and loyalty at a ‘native’ oligarchic holding. The general trend is not towards eliminating informality as a ‘post-Soviet residue’ but rather towards renegotiating it with different outcomes.

description: Silver nanocrystals have been prepared by reacting silver nitrate with ascorbic acid in aqueous solution containing a low concentration of a commercial polynaphtalene sulphonate polymer (Daxad 19). Various crystalline morphologies have been obtained simply by tuning the reaction temperature. We have investigated the nanoparticle formation mechanism at three different temperatures by in situ and time resolved Small Angle X ray Scattering measurements. By modeling the scattering intensity with interacting spherical particles in a fractal-like polymer-Ag matrix, we found signatures of nucleation, growth and assembly of primary particles of about 15-20 nm. We observed how the time evolution of both spatial correlations between primary particles and the dynamic fractal geometry of the polymer-Ag matrix could influence and determine both the aggregation mechanism and the morphology of forming nanostructures in solution.
“I Proved in Court that I am Not a Camel”: Everyday Law among Businesspeople in Russian Local Communities

Subjects: everyday legality; small entrepreneurship; paperwork; bureaucracy; political networks; mobilisation of law; post-Soviet studies; Russia

description: While the rule of law has been an important topic of research for entrepreneurship in transition economies, the relationship entrepreneurs have with the body of law remains understudied. This article explores everyday legality among politically affiliated and non-affiliated businesspeople in Russia; that is, the role of laws, written rules, standards, and requirements in their everyday business activities. Drawing on interviews and participant observations in Russian communities, I trace how an individual’s political position impacts the ability of small entrepreneurs to navigate paperwork and bureaucracy. Utilizing a sociological approach to explore the behaviour of the law among businesspeople, my research demonstrates that although bureaucracy and written rules affect all entrepreneurs, multiple facets of the law constrain or promote an individual’s access to opportunities in different ways. I found that political affiliation strengthens the power to succeed in the bureaucratic game, and to protect one’s interests through court appeals. In contrast, non-affiliated entrepreneurs are limited in their capacity to deal with Russian bureaucracy, and to litigate the state using legal procedures. The main conclusion of the research is that political affiliation is the most significant line of differentiation and inequality among small and medium-sized enterprises because it affects their legal knowledge, their strategies for coping with paperwork, and their opportunities to mobilise the law. In addition, the study of small entrepreneurs also shows that in contemporary Russia everyone depends greatly on the power of the bureaucratic machine, rather than on the power of the law.

Independence or Unification with a Patron State? Not Such Dichotomous Ideas as One Would Think: Evidence from South Ossetia
Creators: name: Hoch, Tomáš

Year: 2020
Subjects: sovereignty, independence, de facto states, conflict transformation, South Ossetia

description: Independence or unification with Russia? That is a question that is constantly present in the South Ossetian public space. Since the dissolution of the Soviet Union, two referendums have been held in South Ossetia on the issue of state sovereignty (in 1992 and 2006). Since 2015, many proclamations have been made by South Ossetian politicians about preparations for another referendum on the subject. In the case of South Ossetia, what one would think as dichotomous ideas – independence and unification with Russia – are in fact overlapping concepts. The aim of this paper is to contribute to a closer understanding of the puzzling current reality in South Ossetia in terms of the debate on unification versus independence. On the one hand, South Ossetia seeks independence, but on the other, it is constantly seeking to join Russia. The second goal of the paper is to identify the factors, which underlie the South Ossetian discourse supporting the idea of unification with the Russian Federation. As a result of the analysis, the author concludes that the issue of security and the idea of a divided nation play a crucial role in this discourse. These topics frequently appear in the statements of the South Ossetian political elite as the main arguments in favour of accession to Russia. In addition, there are several other important variables, which can explain this prevailing South Ossetian narrative: the lack of human and natural resources for a viable state, the fatigue of the South Ossetian population in the face of the incompetence of local elites, and their aspiration for Russian centralisation. Finally, because a fuzzy independence narrative has also been documented in other de facto states, the author seeks an answer to a more general question: Why does this overlap in the narrative of independence versus unification arise in de facto states?

description: Observations of ionized and neutral gas outflows in radio-galaxies (RGs) suggest that AGN radio jet feedback has a galaxy-scale impact on the host ISM, but it is still unclear how the molecular gas is affected. We present deep Spitzer IRS spectroscopy of 8 RGs that show fast HI outflows. All of these HI-outflow RGs have bright H2 mid-IR lines that cannot be accounted for by UV or X-ray heating. This suggests that the radio jet, which drives the HI outflow, is also responsible for the shock-excitation of the warm H2 gas. In addition, the warm H2 gas does not share the kinematics of the ionized/neutral gas. The mid-IR ionized gas lines are systematically broader than the H2 lines, which are resolved by the IRS (with FWHM up to 900km/s) in 60% of the detected H2 lines. In 5 sources, the NeII line, and to a lesser extent the NeIII and NeV lines, exhibit blue-shifted wings (up to -900km/s with respect to the systemic velocity) that match the kinematics of the outflowing HI or ionized gas. The H2 lines do not show broad wings, except tentative detections in 3 sources. This shows that, contrary to the HI gas, the H2 gas is inefficiently coupled to the AGN jet-driven outflow of ionized gas. While the dissipation of a small fraction (<10%) of the jet kinetic power can explain the dynamical heating of the molecular gas, our data show that the bulk of the warm molecular gas is not expelled from these galaxies.

description: This paper proposes new parametric model adequacy tests for possibly nonlinear and nonstationary time series models with noncontinuous data distribution, which is often the case in applied work. In particular, we consider the correct specification of parametric conditional distributions in dynamic discrete choice models, not only of some particular conditional characteristics such as moments or symmetry. Knowing the true distribution is important in many circumstances, in particular to apply efficient maximum likelihood methods, obtain consistent estimates of partial effects and appropriate predictions of the probability of future events. We propose a transformation of data which under the true conditional distribution leads to continuous uniform iid series. The uniformity and serial independence of the new series is then examined simultaneously. The transformation can be considered as an extension of the integral transform tool for noncontinuous data. We derive asymptotic properties of such tests taking into account the parameter estimation effect. Since transformed series are iid we do not require any mixing conditions and asymptotic results illustrate the double simultaneous checking nature of our test. The test statistics converges under the null with a parametric rate to the asymptotic distribution, which is case dependent, hence we justify a parametric bootstrap approximation. The test has power against local alternatives and is consistent. The performance of the new tests is compared with classical specification checks for discrete choice models.

description: Helical structures are common in extragalactic jets. They are usually attributed in the literature to periodical phenomena in the source (e.g., precession). In this work, we use VLBI data of the radio-jet in the quasar S5 0836+710 and hypothesize that the ridge-line of helical jets like this corresponds to a pressure maximum in the jet and assume that the helically twisted pressure maximum is the result of a helical wave pattern. For our study, we use observations of the jet in S5 0836+710 at different frequencies and epochs. The results show that the structures observed are physical and not generated artificially by the observing arrays. Our hypothesis that the observed intensity ridge-line can correspond to a helically twisted pressure maximum is confirmed by our observational tests. This interpretation allows us to explain jet misalignment between parsec and kiloparsec scales when the viewing angle is small, and also brings us to the conclusion that high-frequency observations may show only a small region of the jet flow concentrated around the maximum pressure ridge-line observed at low frequencies. Our work provides a potential explanation for the apparent transversal superluminal speeds observed in several extragalactic jets by means of transversal shift of an apparent core position with time.

description: Recent studies have focused on the role of Official Development Assistance (ODA) in financing infrastructural projects and rural development programmes. This study contributes to this literature by demonstrating how Japanese and Filipino aid authorities facilitate a Japanese-ODA-funded Farm-to-Market Road (FMR) subproject as a solution aiming to achieve overall poverty reduction and rural economic growth in the Philippines. Drawing on Foucault’s governmentality, the paper analyses processes and interactions within the management stages of the FMR subproject. It examines the impact of the completed FMR among agrarian reform beneficiaries (ARBs). It argues that while the FMR fostered mutual understanding and beneficial relationships among aid authorities, more significant advantages were accrued by the non-poor sector. Consequently, ARBs clamour for further support to maximize FMR benefits.

description: Nucleonic matter displays a quantum liquid structure, but in some cases finite nuclei behave like molecules composed of clusters of protons and neutrons. Clustering is a recurrent feature in light nuclei, from beryllium to nickel. For instance, in $^{12}$C the Hoyle state, crucial for stellar nucleosynthesis, can be described as a nuclear molecule consisting of three alpha-particles. The mechanism of cluster formation, however, has not yet been fully understood. We show that the origin of clustering can be traced back to the depth of the confining nuclear potential. By employing the theoretical framework of energy density functionals that encompasses both cluster and quantum liquid-drop aspects of nuclei, it is shown that the depth of the potential determines the energy spacings between single-nucleon orbitals, the localization of the corresponding wave functions and, therefore, the degree of nucleonic density clustering. Relativistic functionals, in particular, are characterized by deep single-nucleon potentials. When compared to non-relativistic functionals that yield similar ground-state properties (binding energy, deformation, radii), they predict the occurrence of much more pronounced cluster structures. More generally, clustering is considered as a transitional phenomenon between crystalline and quantum liquid phases of fermionic systems.

Enamel’s elastic moduli, elastic/inelastic transition were quantified and the toughening mechanisms were identified for different hierarchical levels. During creep, the interrod regions are able to dissipate higher irreversible energy compared to the enamel rod regions. For enamel fracture, the crack tip toughness, the bridging stresses and size of the cohesive zone at the crack-tip were quantified.
Measuring Integration in the Labor Market – Which to Use, the Demographic or the Ethnic Concept?

Subjects: Labor market; immigrants; demographic concept; ethnic concept; Russian-speaking population

description: In most countries, the data and the underlying theoretical approaches tend to emphasize the greater success of the natives or the ethnic majority in the labor market. When measuring integration and success in the labor market, different approaches can be used, for example, the demographic or ethnic concept. The ethnic concept refers to ethnicity, regardless of having an immigrant background or not. The demographic concept instead uses the native/immigrant dimension, usually considering first- and second-generation immigrants. Researchers’ use of these concepts varies by country but rarely do they discuss which concept would be more relevant to measure labor market differences and inequalities. Relevance is defined by how labor market differences and inequalities can be identified most clearly. In recent literature, it is suggested that in Baltic countries statistical categories of ‘international migrant/foreign–born’ (demographic concept) are not relevant to use because migration took place inside the borders. In the current article, the focus is on the Estonian context and the research question, therefore, asks which concept is suitable for the Estonian context when taking the Russian speaking population into consideration in labor market analysis. Results lead to the conclusion that using the demographic concept without making an ethnic distinction could lead to a distorted interpretation of the Russian-speaking population’s labor market integration in the Estonian context. This result also supports the recommendations from previous literature to use an ethnic concept. The study used the Labor Force Survey (LFS) 2013-2014 for the empirical analysis.

description: In the studies of transition states and societies, Estonia and Lithuania are considered as twin cases of the neoliberal Baltic model due to similarities in their political economies and macroeconomic policies. Do similarities between the two countries extend to their class structures? We compare changes of the class composition in Estonia and Lithuania during the 2008-2015 period, encompassing the Great Recession and subsequent recovery. For empirical analysis, we use the European Social Survey (ESS) data and employ the framework of the European Socio-economic Classification (ESeC). We find that by 2015 the class structure of the Estonian society became similar to the class structures in the technologically most advanced post-industrial countries. Changes in the class structure of Lithuania diverged from general trends, preserving many features characteristic of industrial societies.

description: CU Vir and V901 Ori belong among these few magnetic chemically peculiar stars whose rotation periods vary on timescales of decades. We aim to study the stability of the periods in CU Vir and V901 Ori using all accessible observational data containing phase information. We collected all available relevant archived observations supplemented with our new measurements of these stars and analysed the period variations of the stars using a novel method that allows for the combination of data of diverse sorts. We found that the shapes of their phase curves were constant, while the periods were changing. Both stars exhibit alternating intervals of rotational braking and acceleration. The rotation period of CU Vir was gradually shortening until the year 1968, when it reached its local minimum of 0.52067198 d. The period then started increasing, reaching its local maximum of 0.5207163 d in the year 2005. Since that time the rotation has begun to accelerate again. We also found much smaller period changes in CU Vir on a timescale of several years. The rotation period of V901 Ori was increasing for the past quarter-century, reaching a maximum of 1.538771 d in the year 2003, when the rotation period began to decrease. A theoretically unexpected alternating variability of rotation periods in these stars would remove the spin-down time paradox and brings a new insight into structure and evolution of magnetic upper-main-sequence stars.

Negotiating Normative Expectations, Problematic Sustainability and Disempowerment: The Conflicting Realities of Participation Practices in the Estonian Civil Society

Subjects: civil society, Estonia, participation studies, secondary qualitative research, qualitative content analysis

description: Participation is a right held by all community members to engage in decision-making processes. The negotiation power of individuals and interest groups expressed through participatory practices is especially valuable in a young democracy with a short history of civil society and community initiative. Researching participation opens new perspectives into local agency and helps to identify various powers and ideologies in action. Estonian civil society has made notable progress since the country regained its independence, but participatory practices have neither improved in quality nor increased in volume. Furthermore, previous research indicates a discrepancy between normative expectations and empirical reality. This paper draws on a comparative study from 2016 and examines the differences between the Estonian non-profit and the public sectors’ experiences and expectations regarding participation practices. The qualitative content analysis method was employed on the interviews conducted with a total 65 public and third sector representatives. The results are contextualised through critical theories of participation which regard participation as a complex, multidimensional and strongly ideologised solution. The study concludes that the promises of empowerment typical to the mainstream participation rhetoric are yet to be rooted in the practices of participation in Estonian civil society, where instead the repeating motif in the participatory experience is disempowerment.

description: IsaMill™ is utilized mainly for ultrafine grinding of low-grade ores. Although highly efficient, it has certain operational challenges, such as frequent replacement of liners of disks and inner shells. To circumvent this challenge, a design modification of the disks, by introducing a reduced diameter disk (RDD), is commonly implemented. A discrete element method (DEM) based model is developed to investigate the effects of RDD and mill loading on media dynamics, force distribution, power draw, and collision energy. It is demonstrated that implementation of RDD results in a reduction of normal and shear stress on mill parts indicating a reduction in wear. Analysis of media dynamics shows that media mobility decreases hence decreasing total collision energy when RDDs are applied. This reduced mobility can potentially affect the grinding performance of the mill. A single-objective optimization approach based on collision energy data is employed to determine an optimal design configuration of the mill.

description: VoIP (Voice over Internet Protocol) is a growing technology during last decade. It provides the audio, video streaming facility on successful implementation in the network. However, it provides the text transport facility over the network. Due to implementation of it the cost effective solution, it can be developed for the intercommunication among the employees of a prestigious organization. The proposed idea has been implemented on the audio streaming area of the VoIP technology. In the audio streaming, the security vulnerabilities are possible on the VoIP server during communication between two parties. In the proposed model, first the VoIP system has been implemented with IVR (Interactive Voice Response) as a case study and with the implementation of the security parameters provided to the asterisk server which works as a VoIP service provider. The asterisk server has been configured with different security parameters like VPN server, Firewall iptable rules, Intrusion Detection and Intrusion Prevention System. Every parameter will be monitored by the system administrator of the VoIP server along with the MySQL database. The system admin will get every update related to the attacks on the server through Mail server attached to the asterisk server. The main beauty of the proposed system is VoIP server alone is configured as a VoIP server, IVR provider, Mail Server with IDS and IPS, VPN server, connection with database server in a single asterisk server inside virtualization environment. The VoIP system is implemented for a Local Area Network inside the university system

Relativity of mixed entangled states

description: We obtain the necessary and sufficient separability and distillability conditions of mixtures of a maximally entangled state and the completely separable state in relativistic setting. In an inertial frame we study the entanglement under Wigner rotations induced by Lorentz transformations. We also investigate the mixed state entanglement of scalar and Dirac fields as seen by two relatively accelerated observers. For scalar field we show that in infinite acceleration limit the state has no longer distillable entanglement. For dirac field the entanglement in the infinite acceleration limit is finite. In both cases we show that there are states that will change from entangled into separable for a certain value of velocity or acceleration. We conclude that distillability is a relative concept, depending on the frame in which it is observed.

description: The study examines address terms (ATs) used by the Russian ethnic minority of Lithuania (RuL) focusing primarily on the vocative use of anthroponyms and on the zero vocative, including in combination with T/V forms of address. Our aim is to explore how ethnic and social characteristics of offline and online communities can influence address strategies in a multicultural environment and assess possible communicative risks. The article draws on the findings from two studies. We first present data from a survey conducted among RuL speakers examining their prevalent ATs, used alongside T/V forms, in offline communication. We then analyse ATs in the publications and comments sections in popular Facebook social network groups used by the RuL community. The study examines the speech behaviour of the RuL community in light of the geopolitical and sociolinguistic situation and seeks to determine factors influencing the choice of a particular form of address. The findings suggest that the RuL speakers present an emerging new identity of Russian speakers and have implications for future research on the enregisterment practices of ATs among Russian speakers of the post-Soviet space.

Our setting includes the classical "rigid" formulation as a special case and extends it by allowing each dimer to consist of particles at arbitrarily distant sites of the lattice, with the energy of interaction between the particles in a dimer depending on their relative position. We reduce the free energy of the elastic dimer-monomer (EDM) system per lattice site in the thermodynamic limit to the moment Lyapunov exponent (MLE) of a homogeneous Gaussian random field (GRF) whose mean value and covariance function are the Boltzmann factors associated with the monomer energy and dimer potential. In particular, the classical monomer-dimer problem becomes related to the MLE of a moving average GRF. We outline an approach to recursive computation of the partition function for "Manhattan" EDM systems where the dimer potential is a weighted l1-distance and the auxiliary GRF is a Markov random field of Pickard type which behaves in space like autoregressive processes do in time. For one-dimensional Manhattan EDM systems, we compute the MLE of the resulting Gaussian Markov chain as the largest eigenvalue of a compact transfer operator on a Hilbert space which is related to the annihilation and creation operators of the quantum harmonic oscillator and also recast it as the eigenvalue problem for a pantograph functional-differential equation.

description: The Katowice conurbation is the largest traditional economic region in Central Europe and simultaneously a complex settlement system. Yet it faces numerous problems. The article attempts to answer the questions: (1) Does the hitherto relatively uniform economic structure of the Katowice conurbation, based on mining and metallurgy, cause similar intensities of depopulation, demographic ageing and urban shrinkage in 16 neighbouring towns? (2) Is the scope of policies mitigating the effects of these processes similar? The analysis of statistical data for 1999 and 2018 and the development strategies of individual towns shows that both the trends in population changes and the policies adopted towards them differ. The severity of the negative processes varies, with the largest being in Katowice, Sosnowiec and Bytom. Most towns recognize the problem yet consider its solution through selective actions (improvement in housing conditions, development of services or launching new industrial activities). There are also towns that, although seeing problems, marginalize them in their development strategies. Only Czeladź has a multifaceted approach to this problem. The general conclusion shows a need to coordinate the policies of local governments of the entire conurbation for the benefit of multifaceted measures to mitigate depopulation, demographic ageing and urban shrinkage.

description: 深圳在打造“千座公園之城”過程中致力於營造創新城市文化空間肌理。基於生態語言學，本文以深圳灣公園和香蜜公園作為觀察對象，通過田野調研收集語言景觀，並對體驗者評價話語展開生態話語分析（元功能視角），結合給養理論和王陽明心學，建構語言景觀客體與體驗者主體的互動生態哲學，嘗試探索深圳生態型公園的語言景觀特質及其主客體互動關係，引導城市建設者關注城市文化空間的主客體互動效應。分析發現，深圳生態型公園以“智慧”作為角色定位，其語言景觀被賦予了人性化與個性化特質，在語言景觀客體與體驗者主體互動過程中，浮現出訴求與信息的不對稱性，解讀與感知的流變性，以及標記牌在他者、清晰度和充分度面向上的感知差異化。 Shenzhen is devoted to creating an innovative urban cultural spatial mechanism in the process of building a 'City of a Thousand Parks'. From the perspective of Eco-linguistics, this paper took Shenzhen Bay Park and Xiangmi Park as the typical sample.Research collected language landscapes (LLs)through fieldwork and conducted an ecological discourse analysis (from the perspective of meta-functional ) on the evaluation discourse from visitors.Combining with the theory of affordance and School of Mind from Huang YangMing, we constructed an ecological philosophy of interaction between the subject and object, so as to explore the characteristics of LLs and their subject-object interaction from ecological parks in Shenzhen. The aim of this study is to guild urban creators to pay attention to the subject-object interaction effect of urban cultural space.The analysis reveals that,with 'wisdom' as its role positioning, the LLs of ecological parks in Shenzhen has been given the characteristics of humanization and personalization. It was showed asymmetry of claim and information, variations between interpretation and perception, and the perceptual differentiation from the perspective of otherness, clarity and adequacy in the interaction between the LLs and the visitors.

description: Studies by video microscopy on fluctuating colloids measure the real-space cross-correlations in particle motion. This set of correlations is then treated as a matrix, in order to study the spectrum and mode structure. We show that in general the modes are modified by the truncation of the full real-space correlations. We perform a theoretical analysis of the truncation, find the boundary conditions imposed by the truncation, and propose practical windowing strategies to eliminate artefacts. We study the problem from various perspectives, to compile a survey for experimentalists.

When Donors Collide: The Implications of Contradictory Interventions in a Bangladesh Agrarian Environment

description: What are the implications of donor agencies pursuing contradictory approaches in the same locale? The question is interesting for two reasons. The first is that, while critical case studies of individual interventions are common, “donor collision” is not widely reported. The phenomenon poses an alternative explanation for the failure of donor interventions that challenges universalist assertions by both modernists and post-developmentalists. The second reason is that the future of Overseas Development Assistance (ODA) and the interventions of a Global North-dominated donor infrastructure in the Global South are once more topical. Recent contributions have debated the implications of current trends for ODA and its associated policies and practices, collectively defined by Gillian Hart as “big D” (Hart, 2001). Such trends include rising middle classes in the Global South and economic convergence with the North, a “universal” set of Sustainable Development Goals and the now looming challenge of a changing climate. The global problem of contested rights in “agrarian environments” is of particular relevance to these debates. The need to protect the “lungs of the earth” was assuming a higher profile due to the rising urgency of changing climate before the Covid-19 pandemic. With future pandemic risk associated with land use change in biodiversity hotspots, a global focus on conservation and biodiversity is likely to sharpen. The question of how to reconcile conservation outcomes with the land rights of forest dwelling populations is, therefore, of general and increasingly urgent importance. The study is set in an agrarian environment in Bangladesh, where for twenty years different donor agencies have pursued contradictory approaches to this general and urgent question. On the one hand, USAID has supported Forest Department interventions, which are broadly exclusionary and are predicated on the negation of the local Indigenous Peoples’ land rights. On the other, various agencies have supported such rights, explicitly challenging Forest Department authority over the area. Through analysing why and how donors collide in this instance, the study sets out a number implications for general development theory and practice. The three most important are that, first, more work is required on inter-donor conflict as a cause of development failure. Second, the future of big D will continue to be dominated by very old questions of politics, participation and institutions. Finally, blanket endorsement of “national partnership,” particularly in more authoritarian contexts, is likely to result in significant human and environmental costs.

description: We study the spectral and polarization properties of supernova remnants (SNRs) based on our 6cm survey data. The observations were taken from the Sino-German 6cm polarization survey of the Galactic plane. By using the integrated flux densities at 6cm together with measurements at other wavelengths from the literature we derive the global spectra of 50 SNRs. In addition, we use the observations at 6cm to present the polarization images of 24 SNRs. We derived integrated flux densities at 6cm for 51 small SNRs with angular sizes less than 1 degree. Global radio spectral indices were obtained in all the cases except for Cas A. For SNRs G15.1-1.6, G16.2-2.7, G16.4-0.5, G17.4-2.3, G17.8-2.6, G20.4+0.1, G36.6+2.6, G43.9+1.6, G53.6-2.2, G55.7+3.4, G59.8+1.2, G68.6-1.2, and G113.0+0.2, the spectra have been significantly improved. From our analysis we argue that the object G16.8-1.1 is probably an HII region instead of a SNR. Cas A shows a secular decrease in total intensity, and we measured a flux density of 688+/-35 Jy at 6cm between 2004 and 2008. Polarized emission from 25 SNRs were detected. For G16.2-2.7, G69.7+1.0, G84.2-0.8 and G85.9-0.6, the polarized emission is detected for the first time confirming them as SNRs. High frequency observations of SNRs are rare but important to establish their spectra and trace them in polarization in particular towards the inner Galaxy where Faraday effects are important.
