description: Hematopoietic stem cells (HSCs) take on the extraordinary role of sustaining life-long production of blood cells. Despite their indisputable therapeutic potential, HSC biology is poorly understood, and the field remains limited by the inability to maintain, expand, or generate HSCs in vitro. The aim of this study was to elucidate a particular gap in our understanding of the organellar cell biology of HSCs, specifically the role and function of the mitochondria. Several signaling pathways and biological processes converge onto the mitochondria, yet these organelles were found to be largely dispensable in HSCs on the basis of their predominantly glycolytic metabolism and reports of low mitochondrial content. Our studies show that MitoTracker Green (MTG), a frequently used fluorescent dye to measure mitochondrial mass in hematopoietic populations, is effluxed by HSCs resulting in their systematic and deceptive enrichment in the subset of cells with the lowest MTG fluorescence. Using dye-independent methods we discovered that HSCs have elevated mitochondrial content despite their reliance on glycolysis for ATP production. Moreover, mechanisms of mitochondrial quality control and clearance by autophagy appear to be comparatively lower in HSCs than in any other hematopoietic population we analyzed, suggesting HSCs maintain their mitochondria over time. To investigate the function of mitochondria in HSCs we generated mice with disruption of mitofusins (MFN) 1 and 2. These proteins are key mediators of mitochondrial fusion, a process that in coordination with mitochondrial fission regulates mitochondrial size, number, and function. Mice with deletion of Mfn1 and Mfn2 (DKO) die perinatally, are pale in appearance and their HSCs show complete loss of regenerative capacity. Several processes linked to dysfunctional mitochondrial fusion and known to be tightly regulated in HSCs are altered in these mutants, including mitochondrial morphology, mitochondrial mass, proliferation, and altered metabolism. Interestingly, one allele of Mfn1 is sufficient to rescue the hematopoietic function and lethality of DKO mice, while one allele of Mfn2 only rescues myeloid reconstitution. Taken together, our findings highlight the importance and complexity of mitochondrial function and dynamics in HSCs and have contributed to the recently increased appreciation of a vital role for mitochondria in HSCs.

description: We develop further an approach to computing energy-energy correlations (EEC) directly from finite correlation functions. In this way, one completely avoids infrared divergences. In maximally supersymmetric Yang-Mills theory ($\mathcal{N}=4$ sYM), we derive a new, extremely simple formula relating the EEC to a triple discontinuity of a four-point correlation function. We use this formula to compute the EEC in $\mathcal{N}=4$ sYM at next-to-next-to-leading order in perturbation theory. Our result is given by a two-fold integral representation that is straightforwardly evaluated numerically. We find that some of the integration kernels are equivalent to those appearing in sunrise Feynman integrals, which evaluate to elliptic functions. Finally, we use the new formula to provide the expansion of the EEC in the back-to-back and collinear limits.

Caressing the Great: Viscount Montague's Entertainment of Elizabeth at Cowdray, 1591
Creators: name: Breight, Curtis Charles

description: Sussex Archaeological Collections, 127, 147-166
description: The quasi-annual ritual known as the Elizabethan summer progress has often been interpreted as nothing more than royal propaganda and aristocratic submission to state power, but the few surviving accounts of these vents indicate variety in modes of entertainment and more importantly, in the relationship between aristocrat and queen. While spectacles such as the 1575 Kenilworth entertainment constituted a king of insiders' game, in which Leicester enjoyed high favour under Elizabeth, the 1591 Coudray entertainment was hosted by a discontented Roman Catholic lord in a heavily Catholic region of the country. I seek to interpret this event/text by placing it in relevant historical contexts and by revealing how the courtly practice of covert communication allowed Viscount Montague to use the entertainment to address different audiences on multiple levels of signification. The Renaissance concept of honour had a large impact on aristocrats, and Montague had been dishonoured by removal from the lieutenancy of Sussex in 1585, and by constant erosion of his local influence engineered by the Privy Council. In short, Montague was compelled to devise an entertainment which would simultaneously please the queen and derail ny suspicion of his literally treasonous activities undertaken for the Catholic faith, but also preserve his own honour in his community and perhaps create a sense of solidarity among all English Catholics - locally, nationally, and abroad.

description: In this article, we generalize Eberlein's Rigidity Theorem to the singular case, namely, one of the spaces is only assumed to be a CAT(0) topological manifold. As a corollary, we get that any compact irreducible but locally reducible locally symmetric space of noncompact type does not admit a nonpositively curved (in the Aleksandrov sense) piecewise Euclidean structure. Any hyperbolic manifold, on the other hand, does admit such a structure.

description: Intensities of LEED and PED are analyzed from a statistical point of view. The probability distribution is compared with a Porter-Thomas law, characteristic of a chaotic quantum system. The agreement obtained is understood in terms of analogies between simple models and Berry's conjecture for a typical wavefunction of a chaotic system. The consequences of this behaviour on surface structural analysis are qualitatively discussed by looking at the behaviour of standard correlation factors.

description: We point out that the Kitaev materials may not necessarily support Kitaev spin liquid. It is well-known that having a Kitaev term in the spin interaction is not the sufficient condition for the Kitaev spin liquid ground state. Many other spin liquids may be stabilized by the competing spin interactions of the systems. We thus explore the possibilities of non-Kitaev spin liquids in the honeycomb Kitaev materials. We carry out a systematic classification of gapped $\mathbb{Z}_2$ spin liquids using the Schwinger boson representation for the spin variables. The presence of strong spin-orbit coupling in the Kitaev materials brings new ingredients into the projective symmetry group classification of the non-Kitaev spin liquid. We predict the spectroscopic properties of these gapped non-Kitaev spin liquids. Moreover, among the gapped spin liquids that we discover, we identify the spin liquid whose spinon condensation leads to the magnetic Bragg peak structure of the zig-zag magnetic order that was observed in Na$_2$IrO$_3$ and $α$-RuCl$_3$. We further discuss the possibility of gapped $\mathbb{Z}_2$ spin liquid and the deconfined quantum criticality from the zig-zag magnetic order to spin dimerization in pressurized $α$-RuCl$_3$.

Mixed Methods for Mixed Models

Subjects: subject: Statistics
subject: FOS: Mathematics

description: This work bridges the frequentist and Bayesian approaches to mixed models by borrowing the best features from both camps: point estimation procedures are combined with priors to obtain accurate, fast inference while posterior simulation techniques are developed that approximate the likelihood with great precision for the purposes of assessing uncertainty. These allow flexible inferences without the need to rely on expensive Markov chain Monte Carlo simulation techniques. Default priors are developed and evaluated in a variety of simulation and real-world settings with the end result that we propose a new set of standard approaches that yield superior performance at little computational cost.

description: Andracantha phalacrocoracis (Yamaguti, 1939) Schmidt, 1975
D e s c r i p t i o n (figs 1, D; 2, D, K; table 2)
General. Relatively small acanthocephalans. Trunk with discoid widening and two fields of spines in anterior part. Anterior field of spines broadest on ventral surface, narrow dorsally. Posterior field of spines broadest ventrally. Maximum width of bare zone between fields of spines 150. In anterior field of spines, length of spines decreasing from apical (38– 49), to basal (29–31). In posterior field of spines, length of spines increasing from apical (32–37) to median (39–41) and decreasing posteriorly (28). Ventral spines almost reaching posterior end of trunk. Genital spines absent. Proboscis almost cylindrical, with dilatation in posterior third, with 18 longitudinal rows of 11 hooks in each. First 7 hooks large, with strong roots directed posteriorly. Next 4 hooks spiniform, without roots. Proboscis receptacle double-walled, with cerebral ganglion in its anterior third. Neck distinct. Lemnisci sacciform, attached in neck, not reaching level of proboscis receptacle bottom.
 Remarks. Andracantha phalacrocoracis is a common parasite of fish-eating birds. It was initially described by Yamaguti (1939) from pelagic cormorants (Phalacrocoracis pelagicus Pallas) from Shikoku Islands, Japan. This species was also reported from blacklegged kittiwakes Rissa tridactyla (Linnaeus), slaty-backed gull (Larus schistisagus Steineger), black-throated loon (Gavia arctica Linnaeus), hooded crow Corvus cornix (Linnaeus), carrion crow Corvus corone (Linnaeus) and P. pelagicus from the Far East from Chukotka to the Prymorye, Russia (Khokhlova, 1986), from P. pelagicus and bald eagles (Haliaeetus leucocephalus Linnaeus, 1766) from Alaska (Schmidt, 1975; Richardson & Cole, 1997), from the great cormorant Phalacrocorax carbo (Blumenbach) from South Moravia, Poland, on their seasonal migrations (Okulewicz, 2014; Moravec & Scholz, 2016).
 Intermediate hosts for A. phalacrocoracis are unknown. However, several species from the genus Andracantha are known to use amphipods as their intermediate hosts (Atrashkevich, 2008). Fishes from three families, Nototheniidae, Bathydraconidae and Channichthyidae, were reported as the paratenic hosts for these acanthocephalans (Rocka, 2006; Laskowski et al., 2008; Laskowski & Zdzitowiecki, 2009).

description: Recent trends in planning, public policy, and real estate development have favored dense mixed use development clusters in suburban communities. This thesis examines the relationship between such activity zones and adjacent residential property values. Regression analyses were used to determine the significance and direction of this relationship in seven study districts in Miami-Dade County, Florida, with the results analyzed in accordance with each district’s unique physical and contextual features. Although proximity to mixed-use districts was found to be relatively insignificant when compared with other property-oriented variables, its impact on property values was often sizeable, generally positive, and varied substantially in strength depending upon scale and location. This indicates that mixed-use districts are associated with net benefits for adjacent residential properties, and also highlights the importance of design and local context in planning for these developments. In addition, proximity to mixed-use districts was found to have a consistently stronger impact on multi-family residential property values than on those of single-family residential properties.

description: This thesis offers a critical evaluation of the women’s movement in relation to the problem of violence against women in the local context of Malaysia. It provides an analysis of the key strategies employed by local women’s organisations to address various forms of violence against women, including coalition building, engagement with UN mechanisms and the use of the media. This thesis also discusses the challenges of patriarchal cultures and mind-sets facing the local women’s movement, as well as the culture of fear that is prevalent in the Malaysian society and highlights the ways in which local women’s organisations work within the constraints of a semi authoritarian state. In addition, this thesis offers a critical analysis of the language and frameworks adopted by the local women’s movement in order to address the issue of violence against women. More precisely, it examines the ways and extent in which local women’s organisations engage in the framework of feminism and the talk of rights. Overall, this thesis seeks to account for the nuances and complexities involved in local women organising and provide a better understanding of the dynamics of the women’s movement in Malaysia.

description: Most recently, there has been a noticeable rise in the push for use of technology in the classroom.  The advancement in digital science has increased greatly the capacity to explore animations, models, and interesting apps. that should substantially enhance science cognition.  At the same time, there is a great need to increase collaboration in the science classroom.  There is a concern that the collaborative experience will be lost with the use of technology in the classroom.  This study seeks to explore the use of iPads in conjunction with a constructivist learning approach to promote student collaboration.  The participants in this study included two sections of 11th grade AP Chemistry students.  Data was generated from different sources such as teacher observations of classroom interactions patterned after Gilles (2004).  In order to gauge student perception of working in groups with the use of the iPad, survey questions adapted from Knezek, Mills and Wakefield (2012) and group interviews were used (Galleta, 2013).  Learning outcomes were assessed using methods adapted from a study by Lord and Baviskar (2007).  Findings of this study showed high percentages of evidence for increased community, productive student group communication, effective feedback through use of the iPads, and value of the interactive apps., but it also showed that students still preferred face-to-face interactions over virtual interactions for certain learning situations.  The study showed good content learning outcomes, as well as favorable opinions among the students for the effectiveness of the use of iPads in collaborative settings in the classroom.
Locally complete intersection homomorphisms and a conjecture of Quillen on the vanishing of cotangent homology

description: Classical definitions of locally complete intersection (l.c.i.) homomorphisms of commutative rings are limited to maps that are essentially of finite type, or flat. The concept introduced in this paper is meaningful for homomorphisms phi : R \longrightarrow S of commutative noetherian rings. It is defined in terms of the structure of phi in a formal neighborhood of each point of Spec S. We characterize the l.c.i. property by different conditions on the vanishing of the André-Quillen homology of the R-algebra S. One of these descriptions establishes a very general form of a conjecture of Quillen that was open even for homomorphisms of finite type: If S has a finite resolution by flat R-modules and the cotangent complex \cot SR is quasi-isomorphic to a bounded complex of flat S-modules, then phi is l.c.i. The proof uses a mixture of methods from commutative algebra, differential graded homological algebra, and homotopy theory. The l.c.i. property is shown to be stable under a variety of operations, including composition, decomposition, flat base change, localization, and completion. The present framework allows for the results to be stated in proper generality; many of them are new even with classical assumptions. For instance, the stability of l.c.i. homomorphisms under decomposition settles an open case in Fulton's treatment of orientations of morphisms of schemes.

description: This dissertation examines the intersecting changes of African decolonization and the post-World War II internationalization of public health by showing how Cameroonian and French health officials shaped global health programs on the ground in the 1950s and 60s. I approach this topic through the lens of two tightly interwoven developments in Cameroon: the history of colonial mobile health teams created by French military doctors and the advent of postwar global disease eradication campaigns. While colonial medicine and international health are typically treated as distinct historical subjects, I argue that global disease eradication programs in this period in Cameroon relied entirely on colonial mobile health teams and their reformulation after independence as a basis of infrastructure, personnel and knowledge. I specifically assert that Cameroonian and French health officials positioned mobile health teams as cornerstones of national health policy and regional health coordination in Central Africa and, in turn, as the basis for operations of attempted global disease eradication programs within Cameroon.  As Cameroonian, French and international health officials negotiated the work of the mobile health teams through decolonization and the first decade of the independence, they were moreover charting new structures of authority and control over medicine and public health between the global and the local, and forging an international politics of public health rooted in the particular tensions of decolonization in the country.  My project thus demonstrates how Africans charted new models for public health through decolonization, models that reflected both the deeply enduring impact of empire and a new post-colonial politics.

description: Recent years have seen significant advancements in artificial intelligence (AI). Still, we are far from intelligent agents that can visually perceive their surroundings, reason, and interact with humans in natural language, thereby
being an integral part of our lives. As a step towards such a grand goal, this thesis proposes Visual Dialog that requires an AI agent to hold a meaningful dialog with humans in natural, conversational language about visual content. Specifically, given an image, a dialog history, and a question about the image, the agent has to ground the question in the image, infer context from history, and answer the question
accurately. Visual Dialog is disentangled enough from a specific downstream task so as to serve as a general test of machine intelligence while being grounded in vision enough to allow objective evaluation of responses. We collect VisDial, a large dataset of human dialogs on real images to benchmark progress. In order to tackle several challenges in Visual Dialog, we build neural network-based models that reason about the inputs explicitly by performing visual coreference resolution called CorefNMN. To demonstrate the effectiveness of such models, we test them on the VisDial dataset and a large diagnostic dataset, CLEVR-Dialog, which we synthetically generate with fully annotated
dialog states. By breaking down the performance of these models according to history dependency, coreference distance, etc., we show that our models quantitatively
outperform other approaches and are qualitatively more interpretable, grounded, and consistent—all of which are desirable for an AI system. We then apply Visual Dialog to visually-grounded, goal-driven dialog without the need for additional supervision. Goal-driven dialog agents specialize in a downstream task (or goal) making them deployable and interesting to study. We also train these agents from scratch to solely maximize their performance (goal rewards) and study the emergent language. Our findings show that while most agent-invented language is effective (i.e., achieve near-perfect task rewards), they are decidedly not interpretable or compositional. All our datasets and code are publicly available to encourage future research.

description: The nucleation and evolution of bubbles are investigated in the model of an $O(3)$-symmetric scalar field coupled to gravity in the high temperature limit. It is shown that, in addition to the well-known bubble of which the inside region is true vacuum, there exists another decay channel at high temperature which is described by a new solution such that a false vacuum region like a global monopole remains at the center of a bubble. The value of the Euclidean action of this bubble is higher than that of the ordinary bubble; however, the production rate of it can be considerable for a certain range of scalar potentials.

The Decline of Living-in Servants in the Transition to Capitalist Farming: A Critique of the Sussex Evidence
Creators: name: Short, Brian
Publisher: name: Archaeology Data Service
Year: 2021

description: Sussex Archaeological Collections, 122, 147-164
description: The decline of the living-in servant has been taken as a symbolic and necessary part of the overall decline of that special relationship between master and man which had characterized English agriculture before the advent of capitalism. The household links which derived their origin from the close bonding between the provisioners of capital and labour living under the same roof and forming a small unit of production, were seen by Marx to be very characteristic of the feudal mode of production. By separating master and man, by depriving the living-in servant of customary entitlements to board and lodging, and by the progressive proletarianization of agricultural labour, the cash nexus was established and a landless, and mostly casualized, labourer was created. It is this concept of a social and spatial polarization of classes in the English countryside which will be examined here in some detail, with reference to material drawn from Sussex. It will be argued that the concept of class polarization, at least when seen in the perspective of Sussex, has been too simplistic. When one considers, for example, the actual experiences of farm workers, as well as the abstractions of political economy, the situation becomes very much more complex. A re-evaluation is now long overdue.

description: The LHCb Collaboration announced the observation of three narrow structures consistent with hidden-charm pentaquark states. They are candidates of hadronic molecules formed of a pair of a charmed baryon and an anticharmed meson. Among them, the $P_c(4457)$ mass is consistent with earlier predictions of a $Σ_c\bar D^*$ molecule with $I=1/2$. We point out that if such a picture were true, one would have $\mathcal{B}(P_c(4457)\to J/ψΔ^+)/\mathcal{B}(P_c(4457)\to J/ψp)$ at the level ranging from a few percent to about 30%. Such a large isospin breaking decay ratio is two to three orders of magnitude larger than that for normal hadron resonances. It is a unique feature of the $Σ_c\bar D^*$ molecular model, and can be checked by LHCb.

description: This essay seeks to assess the educational disparities undocumented students in K-12 education in New York State face, the root causes of these disparities, and the effectiveness of New York policy in mitigating these achievement gaps. I argue that New York’s policies have a more rhetorical than substantive impact due to the ineffective implementation and funding of 1) bilingual language programs, 2) social benefits and programs to temper the effects of poverty on educational attainment, 3) health services for undocumented immigrants, and 4) accessible and linguistically appropriate mental health counseling for those suffering from trauma. Policies and programs only provide benefits to undocumented immigrant youth when schools and institutions are adequately funded, provide well-resourced bilingual language programs, improved access to routine mental health care, state or federal protections from deportation, and broader policies that allay the effects of low socioeconomic status on in-school readiness. The current sociopolitical system in New York State does not meet the needs of the students nor of the society at large, which should aim integrate youth, cultivate their cultural capital, and provide meaningful opportunities to develop into their full human potential. When the state and society fail to integrate immigrants undocumented and provide them with equitable opportunities for personal and economic achievement, disastrous consequences can occur as result. Without legitimate pathways toward upward social mobility, undocumented immigrants youth are at risk of entering into exploitative informal markets and criminal networks, internalizing their marginalization, or turning to violence. Given the continuous waves of immigration, the rootedness of current undocumented populations, and the fundamental human right to equitable educational opportunities, these issues need to be prioritized by policymakers and school administrators.

description: To provide tools, especially L-operators, for use in studies of rational Yang-Baxter algebras and quantum integrable models when the Lie algebras so(N) (b_n, d_n) or sp(2n) (c_n) are the invariance algebras of their R matrices, this paper develops a presentation of these Lie algebras convenient for the context, and derives many properties of the matrices of their defining representations and of the ad-invariant tensors that enter their multiplication laws. Metaplectic-type representations of sp(2n) and so(N) on bosonic and on fermionic Fock spaces respectively are constructed. Concise general expressions (see (5.2) and (5.5) below) for their L-operators are obtained, and used to derive simple formulas for the T operators of the rational RTT algebra of the associated integral systems, thereby enabling their efficient treatment by means of the algebraic Bethe ansatz.

description: In this letter, a wireless transmitter using the new architecture of programmable metasurface is presented. The proposed transmitter does not require any filter, nor wideband mixer or wideband power amplifier, thereby making it a promising hardware architecture for cost-effective wireless communications systems in the future. Using experimental results, we demonstrate that a programmable metasurface-based 8-phase shift-keying (8PSK) transmitter with 8*32 phase adjustable unit cells can achieve 6.144 Mbps data rate over the air at 4.25 GHz with a comparable bit error rate (BER) performance as the conventional approach without channel coding, but with less hardware complexity.

description: Many organisms facultatively produce different phenotypes depending on their environment, yet relatively little is known about the genetic bases of such plasticity in natural populations. In this study, we describe the genetic variation underlying an extreme form of plasticity--resource polyphenism--in Mexican spadefoot toad tadpoles, Spea multiplicata. Depending on their environment, these tadpoles develop into one of two drastically different forms: a carnivore morph or an omnivore morph. We collected both morphs from two ponds that differed in which morph had an adaptive advantage and performed genome-wide association studies of phenotype (carnivore vs. omnivore) and adaptive plasticity (adaptive vs. maladaptive environmental assessment). We identified four quantitative trait loci associated with phenotype and nine with adaptive plasticity, two of which exhibited signatures of minor allele dominance and two of which (one phenotype locus and one adaptive plasticity locus) did not occur as minor allele homozygotes. Investigations into the genetics of plastic traits in natural populations promise to provide novel insights into how such complex, adaptive traits arise and evolve.

description: Storing and processing massive small files is one of the major challenges for the Hadoop Distributed File System (HDFS). In order to provide fast data access, the NameNode (NN) in HDFS maintains the metadata of all files in its main-memory. Hadoop performs well with a small number of large files that require relatively little metadata in the NN s memory. But for a large number of small files, Hadoop has problems such as NN memory overload caused by the huge metadata size of these small files. We present a new type of archive file, Hadoop Perfect File (HPF), to solve HDFS s small files problem by merging small files into a large file on HDFS. Existing archive files offer limited functionality and have poor performance when accessing a file in the merged file due to the fact that during metadata lookup it is necessary to read and process the entire index file(s). In contrast, HPF file can directly access the metadata of a particular file from its index file without having to process it entirely. The HPF index system uses two hash functions: file s metadata are distributed through index files by using a dynamic hash function and, for each index file, we build an order preserving perfect hash function that preserves the position of each file s metadata in the index file. The HPF design will only read the part of the index file that contains the metadata of the searched file during its access. HPF file also supports the file appending functionality after its creation. Our experiments show that HPF can be more than 40% faster file s access from the original HDFS. If we don t consider the caching effect, HPF s file access is around 179% faster than MapFile and 11294% faster than HAR file. If we consider caching effect, HPF is around 35% faster than MapFile and 105% faster than HAR file.

description: Since the end of the Cold War, the international system has become more cosmopolitan, communicative, and connected. These changes have taken place against a backdrop of intensifying processes of globalization, the unevenness of which has helped redefine possible fields of political action. This dissertation offers an interpretation of how we might go about understanding and representing the intercultural dynamics and forms of politics that constitute the transnational Tibet Movement.

description: A new canonical divergence is put forward for generalizing an information-geometric measure of complexity for both, classical and quantum systems. On the simplex of probability measures it is proved that the new divergence coincides with the Kullback-Leibler divergence, which is used to quantify how much a probability measure deviates from the non-interacting states that are modeled by exponential families of probabilities. On the space of positive density operators, we prove that the same divergence reduces to the quantum relative entropy, which quantifies many-party correlations of a quantum state from a Gibbs family.

description: Shape memory materials have gained considerable attention thanks to their ability to change physical properties when subjected to external stimuli such as temperature, pH, humidity, electromagnetic fields, etc. These materials are increasingly used for a large number of biomedical applications. For applications inside the human body, contactless control can be achieved by the addition of electric and/or magnetic particles that can react to electromagnetic fields, thus leading to a composite biomaterial. The difficulty of developing accurate numerical models for smart materials results from their multiscale nature and from the multiphysics coupling of involved phenomena. This coupling involves electromagnetic, thermal and mechanical problems. This paper contributes to the multiphysics modelling of a shape memory polymer material used as a medical stent. The stent is excited by electromagnetic fields produced by a coil which can be wrapped around a failing organ. In this paper we develop large deformation formulations for the coupled electro-thermo-mechanical problem using the electric potential to solve the electric problem. The formulations are then discretized and solved using the finite element method. Results are validated by comparison with results in the literature.

description: This report describes the rescue excavation of a late 16th-century forge at Blackwater Green, near Crawley, West Sussex. Although two well-preserved timber water-channels and an anvil base were found, recent stream erosion meant that little else connected with the operation of the forge had survived. The case is made for a short-livedforge, the site of which was comprehensively robbed-out and levelled after going out of use.

description: The United States, in cooperation with European governments and international aid organizations, has sponsored the development of independent media as a major component of both conflict interventions and democratization programs, and more recently as part of nation building efforts. This study explores the evolution and export of those dominant democratic media models and their impact on recipient communities in Bosnia, Kosovo, and Macedonia from 2000 to 2007. International donors came to see media development as a silver bullet for democratization efforts to foster freedom of speech, civil society, good governance, as well as an engaged citizenry. Donors and practitioners initially believed that institutions, once established, would function in a specific way, and coupled with assistance to professionalize and commercialize the media sector, would create or at least jump start systems similar to those in the US and Europe. Over the years, policy makers have identified the vital parts of a democratic media system, but what they have failed to fully understand is the dynamic interaction among them. Now, more than fifteen years after the end of the Bosnian war and twelve after the end of the war in Kosovo, numerous assessments by government sponsors and independent evaluators have reported success in achieving fundamental media freedoms in these countries, yet these media sectors have not demonstrated their anticipated transformative power – leaving struggling or dysfunctional organizations in the wake of donor financial retreat. This study argues that media organizations and institutions are trapped between pressures to commercialize and professionalize, which have become conflicting rather than enabling forces when combined with weak economic environments. In each of the countries in this study, a lack of synchronization among reforms, political divisions, and poor economic growth have contributed to a web of interrelated challenges. Despite significant economic reforms, growth and stability have never reached a threshold for systemic change.
