Subjects: Economics

description: The idea of clusters attracts attention of specialists as well as larger public since at least three decades. Presented paper addresses itself to one particularly important aspect of managing clusters: cluster excellence and the ways of achieving it. Despite the on-going debate there are still only a few studies that investigate cluster initiatives performance and management phenomena, identify the success factors underlying cluster initiatives management and compare their influence. The objective of this study was to identify Critical Success Factors of cluster initiatives management. Further development of the field demands constant sophistication of analytical tools and modes of empirical research. There exist a need for selecting and assessing quality of data at researcher’s disposal. It is particularly strongly felt when data come from respondents in social surveys, from participant observation, focus groups sessions, content analysis and so on. Methods listed above always bear some risk of subjectivism and arbitrary decisions of what is good or bad in data we have. AHP method adopted in research which paper is based on offers stronger ways of gathering, selecting and interpreting the validity of data. The proposed Analytic Hierarchy Process framework identified the relative importance of different success factors to cluster initiative management and determined the key areas of activity and management focus. The AHP based interviews conducted among European cluster managers representing 19 cluster initiatives located in 10 countries allowed to identify the following Critical Success Factors: ‘Assuring sustainability of financing’, ‘Development of CI mission, vision, strategy and operational action plan’, ‘Integration building partnerships inside the CI, creation of interpersonal links, social networks, trust’ and ‘Development of cluster’s critical mass and management of partners’ complementarities and interdependencies’. Their joint importance for cluster initiative management success reached 40%, while the remaining 60% was distributed among 16 other factors. The results of this study support more effective management and better organization of cluster development processes. They are specifically tailored for entrepreneurs, willing to initiate or establishing cluster initiatives, as well as managers, responsible for CIs day-to-day operations and other CI stakeholders. They can also be utilized in the political area, as guidance for policy makers in redesigning policies of cluster initiatives support as well as monitoring and evaluation processes, so that they are based on identified CSFs.

description: We study a two-dimensional model of an isolated narrow topological band at partial filling with local attractive interactions. Numerically exact quantum Monte Carlo calculations show that the ground state is a superconductor with a critical temperature that scales nearly linearly with the interaction strength. We also find a broad pseudogap regime at temperatures above the superconducting phase that exhibits strong pairing fluctuations and a tendency towards electronic phase separation; introducing a small nearest neighbor attraction suppresses superconductivity entirely and results in phase separation. We discuss the possible relevance of superconductivity in this unusual regime to the physics of flat band moiré materials, and as a route to designing higher temperature superconductors.
description: We now also include weak nearest-neighbor attractive interactions and find phase separation instead of superconductivity (new Fig. 4)

Subjects: Economics

description: The health status in Bangladesh relies heavily on the government or the public sector for financing and setting overall policies and service delivery mechanisms. Based on a review of secondary data, the paper assesses the overall challenges and evaluates the current situations of health status and health care development in Bangladesh. Here non-empirical study will apply and the analysis will be made from the data and contents collected from various articles and journals published by various authors and released through various sources. This study revealed that Bangladesh had achieved notable improvements in health status by achieving health-related MDGs where infant or child mortality rate and maternal mortality rate have changed insignificantly than many other developing countries and rapidly improving on other key indicators including immunization coverage, and survival from some infectious diseases including malaria, tuberculosis, and diarrhea. However, Bangladesh faces a lot of challenges in its health care system. These challenges must be resolved to improve the existing health system so that the deprived and vulnerable people can get better access to basic health care services.

description: The recent 21st Century Cures Act propagates innovations to accelerate the discovery, development, and delivery of 21st century cures. It includes the broader application of Bayesian statistics and the use of evidence from clinical expertise. An example of the latter is the use of trial-external (or historical) data, which promises more efficient or ethical trial designs. We propose a Bayesian meta-analytic approach to leveraging historical data for time-to-event endpoints, which are common in oncology and cardiovascular diseases. The approach is based on a robust hierarchical model for piecewise exponential data. It allows for various degrees of between trial-heterogeneity and for leveraging individual as well as aggregate data. An ovarian carcinoma trial and a non-small-cell cancer trial illustrate methodological and practical aspects of leveraging historical data for the analysis and design of time-to-event trials.
From failure to success in South African land reform

description: This article assesses the achievement of land reform in South Africa with respect to the number of beneficiaries relative to rural employment and the demand for land and increases in livelihoods and agricultural output. Even though there are islands of success, for the past twenty years the Land Reform Programme has not satisfied these criteria. Implementation has been poor and farm workers’ and farm dwellers’ rights have not been protected. This failure is primarily attributed to the use of group or co-operative farming; inadequate participation by the beneficiaries; the absence, late arrival or poor quality of post-settlement support; and capacity problems in the civil service. Success requires radical change in design and implementation. A reformed programme should be based primarily on family farmer models, from the provision of housing and gardens for supplementary food production to small commercially oriented family farms, and on intensive participation of the beneficiaries or their groups in the identification, planning, implementation and financial management of their projects. This will allow civil servants to focus on the identification of land to be acquired, the approval of land acquisition and investment plans, and the supervision of financial management and implementation of the projects, thereby relieving their capacity constraints. Before scaling up these approaches they should be tested in pilots on a significant scale, sponsored by any group with the required commitment and capabilities. Pilots should be evaluated independently, based on the number of livelihoods created, household food security and agricultural production.
The Bayesian Inversion Problem for Thermal Average Sampling of Quantum Systems

description: In this article, we propose a novel method for sampling potential functions based on noisy observation data of a finite number of observables in quantum canonical ensembles, which leads to the accurate sampling of a wide class of test observables. The method is based on the Bayesian inversion framework, which provides a platform for analyzing the posterior distribution and naturally leads to an efficient numerical sampling algorithm. We highlight that, the stability estimate is obtained by treating the potential functions as intermediate variables in the following way: the discrepancy between two sets of observation data of training observables can bound the distance between corresponding posterior distributions of potential functions, while the latter naturally leads to a bound of the discrepancies between corresponding thermal averages of test observables. Besides, the training observables can be more flexible than finite samples of the local density function, which are mostly used in previous researches. The method also applies to the multi-level quantum systems in the non-adiabatic regime. In addition, we provide extensive numerical tests to verify the accuracy and efficiency of the proposed algorithm.

description: Numerous high-yielding modern maize varieties have been developed for Malawi. However, their performance and returns when managed under real-world conditions are generally unknown. We have used new cross section data to generate insights into the performance of these maize varieties. We first determined optimal portfolios of maize using expected utility maximisation models under a variety of smallholder preference structures. The analysis revealed a trade-off between expected returns and their variability. Modern varieties are high yielding but also pose relatively more downside risk than traditional varieties, perhaps because they are more sensitive to optimal management conditions. Despite this risk, too many smallholders focus exclusively on traditional varieties, and in particular they exclude any modern variety from their portfolio. Factors inhibiting the adoption of modern varieties were examined econometrically. With respect to policy implications, the results suggest that a mix of modern and traditional varieties could be appropriate for many smallholders, and that extension efforts could target specific groups, such as femaleheaded farm households of low socioeconomic status, which face severe constraints in the adoption of modern varieties.
Solitonic Aspects of q-Field Theories

description: We have examined the deformation of a generic non-Abelian gauge theory obtained by replacing its Lie group by the corresponding quantum group. This deformed gauge theory has more degrees of freedom than the theory from which it is derived. By going over from point particles in the standard theory to solitonic particles in the deformed theory, it is proposed to interpret the new degrees of fredom as descriptive of a non-locality of the deformed theory. It also turns out that the original Lie algebra gets replaced by two dual algebras, one of which lies close to and approaches the original Lie algebra in a correspondence limit, while the second algebra is new and disappears in this same correspondence limit. The exotic field particles associated with the second algebra can be interpreted as quark-like constituents of the solitons, which are themselves described as point particles in the first algebra. These ideas are explored for q-deformed SU(2) and $GL_q(3)$.

description: Small polarons (SPs) are known to exist in most important transition metal oxides (TMOs); however, the nature of small polaron formation remains enigmatic, and a fundamental understanding of how SPs impact the intrinsic electronic structure and optical properties of these materials is largely lacking. In this work, we employ first-principles calculations to investigate SP formation in Co$_{3}$O$_{4}$, a highly promising material for a wide range of emerging energy applications, and we resolve the conflicting findings that have been reported on the electronic structure of the system. We confirm that the intrinsic band gap of Co$_{3}$O$_{4}$ is 1.6 eV, and we show that the formation of hole small polarons significantly influences the optical absorption spectra, leading to a 0.8 eV transition that is often misinterpreted as the band edge that defines the fundamental gap. In addition, we discuss how uniaxial strain can be utilized to probe the Jahn-Teller distortion of SP states and in turn, effect their optical transitions. Beyond Co$_{3}$O$_{4}$, our study suggests a general roadmap for establishing a first-principles computational approach that can simultaneously achieve an accurate description of SP states, electronic band structure and optical transitions of polaronic magnetic oxides.

description: This study examines the effects of land tenure systems on resource-use productivity and efficiency in the Upper East region of Ghana with data drawn from the Ghana Agricultural Production Survey. A stochastic frontier model is employed to analyse resource-use productivity and efficiency of the rice farms. The study establishes that rice farms under the various land tenure systems are technically inefficient. Technical efficiency for the pooled sample was 61.80%. The estimated technical efficiencies for the farms under owned, rented and sharecropping were 68.19%, 61.61% and 45.17% respectively. The rice production frontier is influenced by farm size, fertiliser, seed and labour. Furthermore, owned land and fixed rent reduce the inefficiency of rice production. Other factors, such as dibbling and credit access, increase inefficiency, while marital status, extension contact and broadcasting decrease inefficiency in rice production. The study suggests that the formulation of appropriate land policies should gear towards ensuring secure rights to farmlands.

description: Background: Differentiation between purging type (AN-P) and restricting type (AN-R) is common in anorexia nervosa (AN) and relevant for clinical practice. However, differences of personality pathology in eating disorders (ED) and their subtypes, which can be captured by the operationalized psychodynamic diagnosis (OPD) system, have not been systematically investigated to date. Objectives: The aim of this study was to explore differences in personality structure between the subtypes of AN and bulimia nervosa (BN) using the OPD structure questionnaire (OPD-SQ). In addition, the ability of the instrument to support the classification of eating disorders was examined. Materials and Methods: We conducted a retrospective, exploratory study in a subset sample of a larger validation study. The OPD-SQ had been collected from n = 60 patients with AN or BN. Patients were assigned to the ED groups by clinical assessment. Statistical analyses included multivariate analysis of variance (MANOVA) and discriminant analysis. Results: Differences between ED groups were observed on 5 OPD-SQ main scales and 9 subscales, as well as on the global scale. AN-P patients demonstrated the lowest personality structure on most of the main scales and subscales, whereas AN-R patients showed a higher personality structure level as compared to both BN and AN-P patients. The OPD-SQ scales with the largest differences include self-perception, object perception, and attachment to internal objects. Discriminant analysis resulted in satisfactory assignment to ED groups by OPD-SQ subscales. Conclusions: Personality structure was found to be less developed in patients with BN and AN-P as compared to patients with AN-R. Although the results have to be proven in larger prospective studies, these results suggest that the OPD-SQ may be used to support the clinical assessment and classification in patients with EDs.

description: An adaptive design adjusts dynamically as information is accrued and a consequence of applying an adaptive design is the potential for inducing small-sample bias in estimates. In psychometrics and psychophysics, a common class of studies investigate a subject's ability to perform a task as a function of the stimulus intensity, meaning the amount or clarity of the information supplied for the task. The relationship between the performance and intensity is represented by a psychometric function. Such experiments routinely apply adaptive designs, which use both previous intensities and performance to assign stimulus intensities, the strategy being to sample intensities where the information about the psychometric function is maximised. Similar schemes are often applied in drug trials to assign doses dynamically using doses and responses from earlier observations. The present paper investigates the influence of adaptation on statistical inference about the psychometric function focusing on estimation, considering both parametric and non-parametric estimation under both fixed and adaptive designs in schemes encompassing within subject independence as well as dependence through random effects. We study the scenarios analytically, focussing on a latent class model to derive results under random effects, and numerically through a simulation study. We show that while the asymptotic properties of estimators are preserved under adaptation, the adaptive nature of the design introduces small-sample bias, in particular in the slope parameter of the psychometric function. We argue that this poses a dilemma for a study applying an adaptive design in the form of a trade-off between more efficient sampling and the need to increase the number of samples to ameliorate small-sample bias.

description: Regularization modifies the (odd) behaviour of the Abelian Chern-Simons action under parity. This effect happens for any sensible regularization; in particular, on the lattice. However, as in the chiral symmetry case, there exist generalized parity transformations such that the regularized theory is odd, and the corresponding operator verifies a Ginsparg-Wilson like relation. We present a derivation of such a relation and of the corresponding symmetry transformations.

description: Peanuts are a key crop in Uganda and are grown by both male and female farmers, although there is a strong inclination for resource-use decisions to be performed by specific genders. This paper identifies opportunities and participation by women and men in the decision to adopt improved peanut varieties in Uganda using a unique dataset from 20 leading peanut-growing districts in the country. The results indicate that there are gender differences in adopting improved varieties of peanuts. In addition, women in female-headed households are less likely to adopt improved varieties compared to women and men in male-headed households, suggesting that they may have less access to resources than women in male-headed households. The gender of the household head has implications for the adoption of improved technologies by women. Moreover, this imbalance in resource access and income-improving decision-making ability by women may have implications for the adoption of other technologies that could improve household welfare.

description: Wild urban forests may elicit positive and negative emotions, both at a community level and within an individual. This paper examines resident perceptions and use of local forest patches in Baltimore, Maryland across four case study neighborhoods selected for differences in homeownership and forest patch management. Semi-structured interview data reveal residents’ strongly ambivalent attitudes toward urban wilderness across all study sites with only nuanced differences in perceptions based on homeownership and management regime. Baltimore residents living adjacent to forest patches were found to experience some of the restorative benefits associated with immersion in wild nature, even when they do not actually enter the woods. Positive experiences were balanced by negative emotions resulting from the perception that urban wilderness is chaotic and unpredictable. These ambivalent feelings may influence the benefits derived from these urban green spaces, as well as local residents’ desires for their future structure and function as social-ecological spaces.

description: The spin degree of freedom is crucial for the understanding of any condensed matter system. Knowledge of spin-mixing mechanisms is not only essential for successful control and manipulation of spin-qubits, but also uncovers fundamental properties of investigated devices and material. For electrostatically-defined bilayer graphene quantum dots, in which recent studies report spin-relaxation times T1 up to 50ms with strong magnetic field dependence, we study spin-blockade phenomena at charge configuration $(1,2)\leftrightarrow(0,3)$. We examine the dependence of the spin-blockade leakage current on interdot tunnel coupling and on the magnitude and orientation of externally applied magnetic field. In out-of-plane magnetic field, the observed zero-field current peak could arise from finite-temperature co-tunneling with the leads; though involvement of additional spin- and valley-mixing mechanisms are necessary for explaining the persistent sharp side peaks observed. In in-plane magnetic field, we observe a zero-field current dip, attributed to the competition between the spin Zeeman effect and the Kane-Mele spin-orbit interaction. Details of the line shape of this current dip however, suggest additional underlying mechanisms are at play.

description: We explore the metric space of jets using public collider data from the CMS experiment. Starting from 2.3/fb of 7 TeV proton-proton collisions collected at the Large Hadron Collider in 2011, we isolate a sample of 1,690,984 central jets with transverse momentum above 375 GeV. To validate the performance of the CMS detector in reconstructing the energy flow of jets, we compare the CMS Open Data to corresponding simulated data samples for a variety of jet kinematic and substructure observables. Even without detector unfolding, we find very good agreement for track-based observables after using charged hadron subtraction to mitigate the impact of pileup. We perform a range of novel analyses, using the "energy mover's distance" (EMD) to measure the pairwise difference between jet energy flows. The EMD allows us to quantify the impact of detector effects, visualize the metric space of jets, extract correlation dimensions, and identify the most and least typical jet configurations. To facilitate future jet studies with CMS Open Data, we make our datasets and analysis code available, amounting to around two gigabytes of distilled data and one hundred gigabytes of simulation files.

It is shown that the five-brane generates a transition between two asymptotic rolling-radii solutions. Moreover, the five-brane motion always drives the solutions towards strong coupling asymptotically. We present an explicit example of a negative-time branch solution which ends in a brane collision accompanied by a small-instanton transition. The five-dimensional origin of some of our solutions is also discussed.

description: Innate lymphoid cells (ILCs) are tissue resident cells with organ-specific properties. Here, we show that the central nervous system (CNS) encompasses ILCs. In particular, CD3-NK1.1+ cells present in the murine CNS comprise natural killer (NK) cells, ILC1s, intermediate ILC1s (intILC1s) and ex-ILC3s. We investigated the properties of CNS-ILC1s in comparison with CNS-NK cells during steady state and experimental autoimmune encephalomyelitis (EAE). ILC1s characteristically express CXCR3, CXCR6, DNAM-1, TRAIL, and CD200R and display heightened TNF-α production upon stimulation. In addition, ILC1s express perforin and are able to degranulate, although in a lesser extent than NK cells. Within the CNS compartments, ILC1s are enriched in the choroid plexus where very few NK cells are present, and also reside in the brain parenchyma and meninges. During EAE, ILC1s maintain stable IFN-γ and TNF-α levels while in NK cells the production of these cytokines increases as EAE progresses. Moreover, the amount of ILC1s and intILC1s increase in the parenchyma during EAE, but in contrast to NK cells, they show no signs of local proliferation. The upregulation in the inflamed brain of chemokines involved in ILC1 migration, such as CXCL9, CXCL10, and CXCL16 may lead to a recruitment of ILC1s from meninges or choroid plexus into the brain parenchyma. In sum, CNS-ILC1 phenotype, distribution and moderate inflammatory response during EAE suggest that they may act as gatekeepers involved in the control of neuroinflammation.

description: The effects of Ugandan farmers’ attitudes toward risk on their decisions about rice production are closely analysed and discussed. A three-step procedure is proposed: 1) farmers’ characteristics determine farmers’ risk attitudes, 2) their risk attitudes influence yield, and 3) yield affects decisions on acreage. This procedure is based on the assumption that acreage decisions are a reflection of farmers’ actual yields, which are associated with risk-averting farming practices. The estimation results show that age and religion are significantly correlated with farmers’ risk attitude, that risk-averse farmers perform better in terms of yield, and that higher yields subsequently increase acreage for production. These attitudes partly account for the diminishing increase in rice production. The results imply that effective ways to increase rice acreage are to increase the potential yield of rice and to promote rice cultivation for lands that are suited to rice cultivation.

description: We investigate the one-bit MIMO (1b-MIMO) radar that performs one-bit sampling with a time-varying threshold in the temporal domain and employs compressive sensing in the spatial and Doppler domains. The goals are to significantly reduce the hardware cost, energy consumption, and amount of stored data. The joint angle and Doppler frequency estimations from noisy one-bit data are studied. By showing that the effect of noise on one-bit sampling is equivalent to that of sparse impulsive perturbations, we formulate the one-bit $\ell_1$-regularized atomic-norm minimization (1b-ANM-L1) problem to achieve gridless parameter estimation with high accuracy. We also develop an iterative method for solving the 1b-ANM-L1 problem via the alternating direction method of multipliers. The Cram$\acute{\text{e}}$r-Rao bound (CRB) of the 1b-MIMO radar is analyzed, and the analytical performance of one-bit sampling with two different threshold strategies is discussed. Numerical experiments are presented to show that the 1b-MIMO radar can achieve high-resolution parameter estimation with a largely reduced amount of data.

description: É possível identificar inúmeras relações entre os campos da Arte e do Direito. A Arte, nas suas diversas formas de manifestação, é expressiva em criatividade e está sempre às voltas com o incerto, com o inusitado; permite um mergulho no imaginário, no qual o sujeito vive sua fantasia para após retornar a sua realidade. O Direito, tido na modernidade como uma ciência de fontes eminentemente normativas, permanece arraigado aos paradigmas daracionalidade, da certeza, da lógica e do positivismo. Tais diferenças demandam uma contribuição mútua, que enriqueça ambas as áreas. O intercâmbio dessas disciplinas é algo ainda por se solidificar; há um terreno fértil que renderá muitos benefícios se devidamente cultivado. A obra artística pode ser utilizada como exemplo privilegiado para ilustração de questões jurídicas; ou ainda, possibilita o operador jurídico à reflexão e à problematização dequestões que, embora presentes em seu cotidiano, já não mais o afetam. O presente artigo procura explorar alguns aspectos em que é possível conciliar Direito e Arte na produção e reprodução do direito posto e de legge ferenda.

description: Mast cells (MCs) are considered as key effector cells in the elicitation of allergic symptoms, and they are essential players in innate and adaptive immune responses. In mice, two main types of MCs have been described: connective tissue MCs (CTMCs) and mucosal MCs (MMCs). However, little is known about the biological functions of MMCs, which is due to the lack of suitable models to investigate MMCs in vivo. Here, we aimed to generate a mouse model selectively deficient in MMCs. It has been previously described that Cre expressed under the control of the baboon α-chymase promotor is predominantly localized in MMCs. Therefore, we mated α-chymase-Cre transgenic mice with mice bearing a floxed allele of the myeloid cell leukemia sequence 1 (Mcl-1). Mcl-1 encodes for an intracellular antiapoptotic factor in MCs; hence, a selective reduction in MMCs was expected. Our results show that this new mouse model contains markedly reduced numbers of MMCs in mucosal tissues, whereas numbers of CTMCs are normal. Thus, Chm-Cre; Mcl-1fl/fl mice are a useful tool for the investigation of the pathophysiological functions of MMCs in vivo.

description: Technological improvements are generally conceived in economics as identical increases in productivity for all producers. Reality is more complicated-the diffusion of new technologies is generally associated with differential changes in the scale of production, with entry into promising new lines of activity, and in the exit of producers who cannot keep up with the technological pace and are forced out by deteriorating terms of trade. These are the economic processes that revolutionize the technological and social structure of the rural communities in the process of development. This paper outlines a few assumptions and findings of a theory of structural change associated with technological improvement and illustrates it with developments in the dairy and the poultry industries in Israel.

description: Mounting evidence points to a role of the circadian clock in the temporal regulation of post-transcriptional processes in mammals, including alternative splicing (AS). In this study, we carried out a computational analysis of circadian and ultradian rhythms on the transcriptome level to characterise the landscape of rhythmic AS events in published datasets covering 76 tissues from mouse and olive baboon. Splicing-related genes with 24-h rhythmic expression patterns showed a bimodal distribution of peak phases across tissues and species, indicating that they might be controlled by the circadian clock. On the output level, we identified putative oscillating AS events in murine microarray data and pairs of differentially rhythmic splice isoforms of the same gene in baboon RNA-seq data that peaked at opposing times of the day and included oncogenes and tumour suppressors. We further explored these findings using a new circadian RNA-seq dataset of human colorectal cancer cell lines. Rhythmic isoform expression patterns differed between the primary tumour and the metastatic cell line and were associated with cancer-related biological processes, indicating a functional role of rhythmic AS that might be implicated in tumour progression. Our data shows that rhythmic AS events are widespread across mammalian tissues and might contribute to a temporal diversification of the proteome.

3D photophoretic aircraft made from ultralight porous materials can carry kg-scale payloads in the mesosphere

description: We show that photophoretic aircraft would greatly benefit from a three-dimensional (3D) hollow geometry that pumps ambient air through sidewalls to create a high-speed jet. To identify optimal geometries, we developed a theoretical expression for the lift force based on both Stokes (low-Re) and momentum (high-Re) theory and validated it using finite-element fluid-dynamics simulations. We then systematically varied geometric parameters, including Knudsen pump porosity, to minimize the operating altitude or maximize the payload. Assuming that the large vehicles can be made from previously demonstrated nanocardboard material, the minimum altitude is 55 km while the payload can reach 1 kilogram for 3D structures with 10-meter diameter at 80 km altitude. In all cases, the maximum areal density of the sidewalls cannot exceed a few grams per square meter, demonstrating the need for ultralight porous materials.

description: We present theoretical results for (gamma,pi0 pi0) and (gamma,pi+- pi0) production on nucleons and nuclei in the kinematical region where the scalar isoscalar pi pi amplitude is influenced by the sigma pole. The final state interaction of the pions modified by the nuclear medium produces a spectacular shift of strength of the pi0 pi0 invariant mass distribution induced by the moving of the sigma pole to lower masses and widths as the nuclear density increases.
