description: The "Cabibbo Angle Anomaly" (CAA) originates from the disagreement between the CKM elements $V_{ud}$ and $V_{us}$ extracted from superallowed beta and kaon decays, respectively, once compared via CKM unitarity. It points towards new physics with a significance of up to $4\,σ$, depending on the theoretical input used, and can be explained through modified $W$ couplings to leptons. In this context, vector-like leptons (VLLs) are prime candidates for a corresponding UV completion since they can affect $W\ellν$ couplings at tree-level, such that this modification can have the dominant phenomenological impact. In order to consistently asses the agreement with the data, a global fit is necessary which we perform for gauge-invariant dimension-6 operators and all patterns obtained for the six possible representations (under the SM gauge group) of VLLs. We find that even in the lepton flavour universal case, including the measurements of the CKM elements $V_{us}$ and $V_{ud}$ into the electroweak fit has a relevant impact, shifting the best fit point significantly. Concerning the VLLs we discuss the bounds from charged lepton flavour violating processes and observe that a single representation cannot describe experimental data significantly better than the SM hypothesis. However, allowing for several representations of VLLs at the same time, we find that the simple scenario in which $N$ couples to electrons via the Higgs and $Σ_1$ couples to muons not only explains the CAA but also improves the rest of the electroweak fit in such a way that its best fit point is preferred by more than $4\,σ$ with respect to the SM.

Combination of the W boson polarization measurements in top quark decays using ATLAS and CMS data at $\sqrt{s} =$ 8 TeV

description: The combination of measurements of the W boson polarization in top quark decays performed by the ATLAS and CMS Collaborations is presented. The measurements are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 8 TeV, and corresponding to an integrated luminosity of about 20 fb$^{-1}$ for each experiment. The measurements used events containing one lepton and having different jet multiplicities in the final state. The results are quoted as fractions of W bosons with longitudinal ($F_0$), left-handed ($F_\mathrm{L}$), or right-handed ($F_\mathrm{R}$) polarizations. The resulting combined measurements of the polarization fractions are $F_0 =$ 0.693 $\pm$ 0.014 and $F_\mathrm{L} =$ 0.315 $\pm$ 0.011. The fraction $F_\mathrm{R}$ is calculated from the unitarity constraint to be $F_\mathrm{R} = -$0.008 $\pm$ 0.007. These results are in agreement with the standard model predictions at next-to-next-to-leading order in perturbative quantum chromodynamics and represent an improvement in precision of 25 (29)% for $F_0$ ($F_\mathrm{L}$) with respect to the most precise single measurement. A limit on anomalous right-handed vector ($V_{\text{R}}$), and left- and right-handed tensor ($g_{\text{L}},g_{\text{R}}$) tWb couplings is set while fixing all others to their standard model values. The allowed regions are [$-$0.11, 0.16] for $V_{\text{R}}$, [$-$0.08, 0.05] for $g_{\text{L}}$, and [$-$0.04, 0.02] for $g_{\text{R}}$, at 95% confidence level. Limits on the corresponding Wilson coefficients are also derived.

description: New sources of CP violation beyond the Standard Model are crucial to explain the baryon asymmetry in the Universe. We discuss the impact of new CP violating interactions in theories where a dark matter candidate is predicted by the cancellation of gauge anomalies. In these theories, the constraint on the dark matter relic density implies an upper bound on the new symmetry breaking scale from which all new states acquire their masses. We investigate in detail the predictions for electric dipole moments and show that if the relevant CP-violating phase is large, experiments such as the ACME collaboration will be able to fully probe the theory.

description: This paper addresses the role of ethical consumers in the transition process towards a sustainable food supply. The questions that immediately come to mind are: can the consumers put changes in motion in the established food supply regime? Which are the mechanisms hindering a transition driven by consumers? In order to answer to these questions we analyse the case of Gruppi di Acquisto Solidale (Solidarity Purchasing Groups) in Italy, as a support for a broader reflection to the topic. The growing dissatisfaction with the established food supply, dominated by the duopoly supermarket-global food supplier, has driven a few pioneers to search for new solutions. In the case of Italy, consumers have organized themselves into informal networks, in order to purchase quality food together from local farmers. They are motivated by the meeting of social, ethical and environmental needs (providing sustainable food and support local farmers) which were not served in the beginning by incumbent firms and they operate in the social economy as community groups

L'analisi viene condotta in quattro diversi livelli di aggregazione con un periodo di tempo comune. I confronti dell'instabilità di esportazioni agricole con quella del totale delle esportazioni di merci sono realizzati allo scopo di accertare se le esportazioni agricole sono più instabili . Il rapporto frale instabilità dei mercati mondiali e quello dei singoli esportazioni dei paesi viene poi esaminato . The present study extends the analysis of export instability in developing countries to a detailed consideration of the instability of agricultural exports, which represent a large part of total exports from developing countries and seem to be particularly prone to fluctuations of various kinds. In order to obtain a full picture of agricultural export instability, the analysis is conducted at four different levels of aggregation with a common time period. Comparisons of the instability of agricultural exports with that of total merchandise exports are made in order to ascertain whether agricultural exports are more unstable. The relationship between the instability of world markets and that of individual country exports is then examined. Tests are also made of the possible effects of agricultural export instability on developing countries’ economies, and the results are compared with those of similar tests conducted for total exports.

description: This study aims to contribute to the understanding of factors influencing the sustainable farmland management in Niger. Specifically, it examines the determinants of adoption of sustainable land management practices including measures to combat erosion, and the use of manure, residues and fertilizer with a view to support the formulation of efficient land use policies based on evidences given fact that the impact of factors influencing farmland management appears to be specific to each context. The study is based on data from the National Survey of Household Living Conditions and Agriculture of 2011 (ECVMA-2011) analyzed within the framework of multivariate Probit model. The results show that there are unobservable interdependences between the decisions on farmland management practices. Furthermore, several types of factors related to access to physical, human, financial and biophysical capitals as well as infrastructure and services seem to play an important role. In addition, it appears that more security is needed in land tenure for a sustainable farmland management while farmland defragmentation can act negatively on sustainable farmland management.

description: We statistically study vortex reconnections in quantum fluids by evolving different realizations of vortex Hopf links using the Gross--Pitaevskii model. Despite the time-reversibility of the model, we report a clear evidence that the dynamics of the reconnection process is time-irreversible, as reconnecting vortices tend to separate faster than they approach. Thanks to a matching theory devised concurrently in Proment and Krstulovic (arXiv:2005.02047), we quantitatively relate the origin of this asymmetry to the generation of a sound pulse after the reconnection event. Our results have the prospect of being tested in several quantum fluid experiments and, theoretically, may shed new light on the energy transfer mechanisms in both classical and quantum turbulent fluids.

description: Nel " periodo d'oro " degli anni 1950 e 1960 la crescita economica nei paesi capitalisti avanzati ha superato tutti i record storici . La performance di crescita nel 1970 si è quindi significativamente deteriorata , e il ritmo di inflazione è più che raddoppiato . Il presente lavoro si concentra sui temi del rallentamento dei tassi di crescita e l'accelerazione degli aumenti dei prezzi in questo periodo . L'aurore analizza per prima cosa le favoreboli condizioni degli anni '50 e '60 e le buone politiche applicate . sucessivamente viene analizzato il deterioramentonegli delle politiche economiche negli anni '70 . Infine viene trattato il grado di successo o il fallimento della politica economica negli anni '70 . In the “golden age” of the 1950s and 1960s economic growth in the advanced capitalist countries surpassed virtually all historical records. Growth performance in the 1970s then deteriorated significantly, and the pace of inflation more than doubled. The present paper looks at questions related to the slowdown in growth rates and the acceleration of price increases in this period. The author first analyses to what extent favourable performance in the 50s and 60s was due to chance or good policy. Conversely, the extent to which deterioration in the 70s was due to circumstance or bad policy is then considered. Finally, the degree of success or failure of economic policy in the 70s is dealt with. JEL: E31, E65

description: The literature on agricultural commodity price volatility in Nigeria has constantly reflected that an excessive price movement is harmful for both producers and consumers, particularly for those who are not able to cope with that new source of economic uncertainty. It has also raised an extensive debate on the main determinants behind the large agricultural commodity price swings observed in the last years without recourse for the price generating process. To narrow this gap, the study examined the price generating process and volatility in the Nigerian agricultural commodities market using secondary data for price series on meat, cereals, sugar, dairy and aggregate food for the period of January 1990 to February 2014. The data were analysed using the linear Gaussian State-Space (SS) model. The results of the descriptive statistics showed that the coefficients of variation for cereals (39.88%), food (32.65%) and dairy price (43.08%) were respectively higher during the overall time period (January 1990 to February 2014) than during the first (January 1990 to January 2002) and second (February 2002 to February 2014) sub-time periods. The results of the inferential statistics showed that authoregressive moving average (ARMA) model is the most selected Nigeria agricultural commodity price generating model for the time periods, that a unit increase in the past price state of cereals, dairy, sugar, meat and aggregate food would increase the future price of sugar, meat and aggregate food by N0.14, N0.28 and N0.15 respectively but decrease future price of cereals and dairy by about N1.00 and N0.21 respectively, and that the one-step ahead predicted value for the first out-of-sample period for cereals, meat, dairy and sugar price were 6317.86, 10.24 and 2.06 respectively. The Nigerian agricultural commodity prices have experienced high variability over the period, and such volatility, price-generating process and the determinants of the Nigerian food commodities prices can best be described by the simple ARMA model with time-variant hyperparameters.

description: In attempting to achieve household food security for smallholder farmers, synergies and tradeoffs exist between cash cropping, food cropping and food security. Available evidence on the impact of cash cropping on food security shows mixed results. The objective of this paper was to assess the impact of export horticulture farming on food security of smallholder farmers in Kenya in two provinces in different agro-ecological zones with different resource and infrastructural endowments, crop growing and marketing conditions. This was done using propensity score matching. The results indicate a positive impact on food security in high potential area and a negative impact in the arid area that is already food deficit. Encouraging export horticulture or cash cropping, aiming at achieving household food security, may not be a one size fit all. Regional differences and particular growing and marketing conditions as well as intra household income distribution patterns play a role and should be considered.

description: Detachment, an important mechanism for reducing target heat deposition, is achieved through reductions in power, particle and momentum; which are induced through plasma-atom and plasma-molecule interactions. Experimental research in how those reactions precisely contribute to detachment is limited. In this work, we investigate a new spectroscopic technique to utilise Hydrogen Balmer line measurements to 1) disentangle the Balmer line emission from the various plasma-atom and plasma-molecule interactions; and 2) quantify their contributions to ionisation, recombination and radiative power losses. During detachment, the observed $Hα$ emission often strongly increases, which could be an indicator for plasma-molecule interactions involving $H_2^+$ and/or $H^-$. Our analysis technique quantifies the $Hα$ emission due to plasma-molecule interactions and uses this to 1) quantify the Balmer line emission contribution due to $H_2^+$ and/or $H^-$; 2) subsequently estimate its resulting particle sinks/sources and radiative power losses. Its performance is verified using synthetic diagnostic techniques of both detached TCV and MAST-U SOLPS-ITER simulations. Experimental results of this technique on TCV data show a bifurcation occurs between the measured total $Hα$ and the atomic estimate of $Hα$ emission, indicative of the presence of additional $Hα$ due to plasma-molecule interactions with $H_2^+$ (and/or $H^-$). An example analysis shows that the hydrogenic line series, even $Lyα$ as well as the medium-n Balmer lines can be significantly influenced by plasma-molecule interactions by tens of percent during which significant Molecular Activated Recombination (MAR) is expected.
Toward an understanding of context-awareness and collaborative narratives in mobile video creation

Publisher: name: University of British Columbia
Year: 2011

description: As computing technology and multimedia become increasingly intertwined, there is growing evidence of a shift in the way users engage with multimedia. Computing technology is facilitating a transformation- media consumers are becoming media producers. This democratization of creativity, which began with blogging, has now moved into the realm of visual multimedia. One of the major agents of this change is the programmable smart phone. Its portability allows for spontaneous, serendipitous and simple media capture in ways not previously possible. These mobile phones host a number of media capture devices along with their communications technologies, including still and video cameras. However, most of these are merely miniaturizations of traditional media capture devices, and thus prevent more sophisticated interactions. Leveraging the paradigms of context-aware computing, we can build systems that allow users to interact with media capture in entirely new and useful ways. We have designed a system called Scheherazade that facilitates context-aware capture of video via mobile phones. This system also allows for these video clips to be combined with clips provided by other users, creating collaborative video narratives. We conducted a user study using this system, to determine the usefulness of different types of context. In performing this analysis, we have discovered contextual information that is gathered through user interaction and contextual information gathered automatically are not equally useful when engaging with video captured on smart phones. We discuss design considerations for utilizing manual or automatic context and directions for future work in this area. The research presented here is an initial exploration into how context-awareness can enhance media capture and sharing on mobile devices.

description: In a concurrent work, Villois et al. 2020 reported the evidence that vortex reconnections in quantum fluids follow an irreversible dynamics, namely vortices separate faster than they approach; such time-asymmetry is explained by using simple conservation arguments. In this work we develop further these theoretical considerations and provide a detailed study of the vortex reconnection process for all the possible geometrical configurations of the order parameter (superfluid) wave function. By matching the theoretical description of incompressible vortex filaments and the linear theory describing locally vortex reconnections, we determine quantitatively the linear momentum and energy exchanges between the incompressible (vortices) and the compressible (density waves) degrees of freedom of the superfluid. We show theoretically and corroborate numerically, why a unidirectional density pulse must be generated after the reconnection process and why only certain reconnecting angles, related to the rates of approach and separations, are allowed. Finally, some aspects concerning the conservation of centre-line helicity during the reconnection process are discussed.

description: A vortex line passes through as many pinning centers as possible on its way from one extremety of the superconductor to the other at the expense of increasing its self-energy. In the framework of the Ginzburg-Landau theory we study the relative growth in length, with respect to the straight line, of a vortex near a zigzag of defects. The defects are insulating pinning spheres that form a three-dimensional cubic array embedded in the superconductor. We determine the depinning transition beyond which the vortex line no longer follows the critical zigzag path of defects.

description: Method-level historical information is useful in research on mining software repositories such as fault-prone module detection or evolutionary coupling identification. An existing technique named Historage converts a Git repository of a Java project to a finer-grained one. In a finer-grained repository, each Java method exists as a single file. Treating Java methods as files has an advantage, which is that Java methods can be tracked with Git mechanisms. The biggest benefit of tracking methods with Git mechanisms is that it can easily connect with any other tools and techniques build on Git infrastructure. However, Historage's tracking has an issue of accuracy, especially on small methods. More concretely, in the case that a small method is renamed or moved to another class, Historage has a limited capability to track the method. In this paper, we propose a new technique, FinerGit, to improve the trackability of Java methods with Git mechanisms. We implement FinerGit as a system and apply it to 182 open source software projects, which include 1,768K methods in total. The experimental results show that our tool has a higher capability of tracking methods in the case that methods are renamed or moved to other classes.

Las bacterias xerotolerantes, es decir resistentes a la desecación, desempeñan un papel esencial en la rizosfera de las plantas. Uno de los mecanismos para tener éxito en ambientes extremos, es la síntesis de trehalosa; un disacárido que previene la pérdida de agua intracelular [1]. Escherichia coli es capaz de producir trehalosa mediante una ruta que involucra la enzima trehalosa 6 fosfato sintasa que cataliza la formación del enlace entre UDP glucosa y Glucosa 6 fosfato para producir una molécula de trehalosa 6 fosfato, luego la enzima  trehalosa 6 fosfato fosfatasa desfosforila a trehalosa 6P para producir una molécula de trehalosa [2]. Por lo tanto, en este trabajo hicimos un alineamiento múltiple con Clustal Omega utilizando secuencia de fosfatasas y el modelado por homología con SWISS-MODEL, generamos el modelo tridimensional de la fosfatasa de Escherichia coli basado en las coordenadas atómicas de la fosfatasa de Salmonella typhimurium depositada en el PDB. Además, de proponer mutaciones que permitieron conocer más sobre la funcionalidad de los aminoácidos en el sitio activo de la enzima, se propone que estas mutantes podría ser más activas que la enzima nativa, producir más trehalosa y en un futuro usar los  genes que codifican para estas enzimas y   transformar  a cepas promotoras del crecimiento vegetal que no sean xerotolerantes para mejorar la productividad de las plantas cultivadas.

description: Negli ultimi anni , la politica monetaria italiana è stata basata sempre più sui controlli amministrativi . Tra le tesi , i più significativi sono i limiti della crescita e vincoli della composizione del portafoglio. Questo articolo ha esaminato l' effetto dei limiti di crescita , ossia il loro effetto , da un punto di vista geografico della struttura e sul sul bancario italiano . In recent years, Italian monetary policy has become increasingly based on administrative controls. Among theses, the most important are the limits of growth and constraints of the portfolio composition. The former impose a maximum growth rate of total loans in lire on banks, while the latter obliges them to invest a given amount of the increases in deposits in securities with specific characteristics. The present article examines a side effect of growth limits, namely their effect from a geographical point of view and on the structure of the Italian banking system. In particular, the author shows that the occurrence of growth ceilings for a given bank is greater the more rapid the increase in its deposits and the smaller the geographical area in which it operates.

description: In this work we provide experimental insights into the impact of plasma-molecule interactions on the target ion flux decrease during divertor detachment achieved through a core density ramp in the TCV tokamak. Our improved analysis of the hydrogen Balmer series shows that plasma-molecule processes are strongly contributing to the Balmer series intensities and substantially alter the divertor detachment particle balance. We find that Molecular Activated Recombination (MAR) ion sinks from $H_2^+$ and/or $H^-$ are a factor $\sim$ 5 larger than Electron-Ion Recombination (EIR) and are a significant contributor to the observed reduction in the outer divertor ion target flux. Molecular Activated Ionisation (MAI) may also be significant during detachment. Plasma-molecule interactions enhance the Balmer line series emission strongly near the target as detachment proceeds. This indicates enhancements of the Lyman series, potentially affecting power balance in the divertor. As those enhancements vary spatially in the divertor and are different for different transitions, they are expected to result in a separation of the $Lyβ$ and $Lyα$ emission regions. This may have implications for the treatment and diagnosis of divertor opacity. The demonstrated enhancement of the Balmer series through plasma-molecule processes potentially poses a challenge to using the Balmer series for understanding and diagnosing detachment based only on atom-plasma processes.
title: Past Environmental Change On The Eastern Andean Flank, Ecuador
Creators: name: Keen, Hayley Frances

description: The eastern Andean flank of Ecuador (EAF) contains some of the world’s most biodiverse ecosystems. Andean montane forests are threatened due to anthropogenic pressures and both current and projected climate change. This thesis examines the palaeoecological history of two stratigraphic sequences (Mera Tigre West [MTW] and Mera Tigre East [MTE]) obtained from the Ecuadorian modern lower montane forest. The sediments preserved were analysed using eight analytical techniques, allowing an insight into the ecosystem’s potential response to projected changes derived from their past responses. Palaeoecological studies on the EAF are rare, and those that do exist are debated relating to: i) the inference of robust ecological data from pollen records in floristically diverse locations, and ii) the past source area of sediments preserved in fluvially exposed sequences, potentially leading to contamination with older material.

 A statistical sub-sampling tool was developed (debate i), capable of producing statistically robust count sizes for each pollen sample; MTW and MTE count sizes ranged from 196-982 showing the diversity within sequences. The depositional environment of MTE was analysed, investigating sediment provenance throughout (debate ii). Results found that large scale volcanic events were critical in the preservation of the sediments, whereas fluvial influence caused a regional sediment source area in the upper stratigraphy, impacting on the palynological interpretation of MTE. Pollen records demonstrated the presence of a diverse vegetation community with no modern analogue at MTE (abundant taxa (>15 %): Hedyosmum, Wettinia, Ilex) and upper montane forest at MTW (Alnus, Hedyosmum, Podocarpus). Fire was not the main driver for the vegetation reassortment at either site (MTW correlation coefficient: -0.37, MTE: 0.16). The two sites have demonstrated the EAF plays host to floristically dynamic ecosystems, susceptible to drivers of change (fire and landscape) and should be considered when predicting the montane forests’ future response to environmental change.

description: The realization of equilibrium superradiant quantum phases (photon condensates) in a spatially-uniform quantum cavity field is forbidden by a "no-go" theorem stemming from gauge invariance. We here show that the no-go theorem does not apply to spatially-varying quantum cavity fields. We find a criterion for its occurrence that depends solely on the static, non-local orbital magnetic susceptibility $χ_{\rm orb}(q)$, of the electronic system (ES) evaluated at a cavity photon momentum $\hbar q$. Only 3DESs satisfying the Condon inequality $χ_{\rm orb}(q)>1/(4π)$ can harbor photon condensation. For the experimentally relevant case of two-dimensional (2D) ESs embedded in quasi-2D cavities the criterion again involves $χ_{\rm orb}(q)$ but also the vertical size of the cavity. We use these considerations to identify electronic properties that are ideal for photon condensation. Our theory is non-perturbative in the strength of electron-electron interaction and therefore applicable to strongly correlated ESs.

description: Die vorliegende Forschungsarbeit geht der Frage nach, wie stark Familien mit einem oder mehreren Primarschulkindern ihre Belastung, verursacht durch Hausaufgaben, einschätzen. Mittels einer Fragebogenerhebung bei einer Stichprobe von N= 142 Familien aus dem Kanton St.Gallen wurde untersucht, inwieweit es einen Zusammenhang zwischen dem durch die Eltern eingeschätzten Belastungswert und dem sonderpädagogischen Förderbedarf, der Erstsprache des Kindes, der alltäglichen Belastung einer Familie und weiteren Merkmalen gibt. Die Ergebnisse zeigen, dass 36 Prozent der befragten Familien im Mittel erheblich oder hoch belastet sind durch die Hausaufgaben ihrer Kinder. Zudem zeigen sich signifikante Zusammenhänge bei Familien, welche bereits durch den Alltag hoch belastet sind oder deren Kind zusätzlich Förderbedarf aufweist. Aus diesen Erkenntnissen werden pädagogische Konsequenzen theoriegestützt hergeleitet und interpretiert. Hausaufgabenkonzepte müssen überarbeitet und weiterentwickelt und Lehrpersonen sensibilisiert werden, um das Risiko der Überbelastung zu minimieren.

description: We analyzed the relationship between forest productivity (joint effect of forest maturity andsoil quality) and total soil respiration (?mol CO2 m􀀀2 s􀀀1) in semi-arid juniper woodlands (youngwoodlands growing in abandoned farmlands with deeper soils, and mature woodlands in lithicsoils), and investigated the seasonal variation in soil CO2 efflux as a function of soil temperatureand the soil water content. We measured the soil CO2 efflux from twelve cylinders in the soil over athree-year period using LI-6400 equipment. The results show that, in the more productive site (youngwoodland), soil CO2 efflux was higher due to greater respiration, mainly in the driest periods. Soilrespiration followed a seasonal trend, being higher in spring and decreasing in cold periods. In bothjuniper woodlands and especially in the older forest, the CO2 efflux rates were low (<2.5 for Q10),typical of slow-growing species. Soil respiration was controlled by soil temperature without droughtand in the temperate-warm season, whereas respiration showed sensitivity to soil water contentin periods when edaphic humidity was low (but only in the more productive, young forest, whichseemed to show better adaptation to drought), and under high soil moisture (soil water > 25%) forboth woodlands, coinciding with warm temperatures in the spring. This period also corresponded tothe highest CO2 efflux recorded in both woodlands. The accumulation of organic C seems to also beimportant to maintain elevated soil respiration in summer, especially in young woodlands. Thus,apart from microclimatic conditions, factors related to productivity regulate respiratory activity.

description: A Zselic aprófalvas térségét joggal nevezhetik „elfelejtett tájnak”, mivel még szakmai körökben sem kap kellő figyelmet, mint ahogy azt a települések drasztikus ütemű népességfogyása és eltűnése indokolná. Jelen tanulmány célja, hogy a statisztikai mutatók elemzésével, térképi interpretációjával jelenítse meg a táj 63 településének alapvető infrastrukturális, demográfiai viszonyait. Az aprófalvakat jellemző releváns adatokat klaszteranalízis módszerével elemeztük, és rávilágítottunk a táj településeinek eltérő fejlettségbeli képére, annak lehetséges okaira. A klaszterbesorolások térképi ábrázolásával a terület térszerkezeti vonásai figyelhetőek meg. Az eredmények alátámasztják azt a hipotézist, miszerint a Zselic települései közül az 500 fő népességet meghaladóak is mutathatnak aprófalvakra jellemző tulajdonságokat. A mutatók által alkotott fejlettségi klasztercsoportok újraértelmezik az eddig pusztán népességszámhoz kötött aprófalu fogalmat. A kutatás eredményeivel és következtetéseivel szeretnénk felhívni a figyelmet a Zselici települések negatív folyamataira, azok következményeire. ------------------------------------------------------ The Zselic region is one of the classical small- and microvillage areas in Hungary which is prone to demographic erosion, unemployment and a deteriorating basic infrastructure. According to preliminary studies and the literature, the region has not got as much attention and support which would be justified by the decreasing population and declining settlements. The research aims at taking a snapshot of the current stage of development here, using multivariate analysis on the regional statistics. The paper takes an analysing approach to the social, economic and infrastructural conditions in the Zselic settlements are studied by a secondary cluster analysis of statistical data whereby villages with similar attributes can be grouped and the reasons for their similarities explained. The mapping of the clusters allows the spatial representation of the development differences in the region. The assumption that Zselic settlements with more than 500 inhabitants may also struggle with similar problems as the small and microvillages was confirmed by the analysis. With the research we would like to draw attention to the negative tendencies in the region.
