(In)Security and Policing in a Marginalized Mexico City Neighborhood: Perceptions, Experiences and Practices
Creators: name: Müller, Markus-Michael
Publisher: name: Columbia University
Year: 2009
Subjects: Latin Americans

description: Reflecting a more general regional trend in the rise of urban crime and violence throughout Latin America (IBRD 2008; Koonings and Kruijt 2007a; Rotker 2002), since the mid 1990s, Mexico City witnessed a "metropolization of crime" (Castillo 2008: 181). Although official statistics indicate a tendential decline of reported crime rates since the late 1990s, victimization studies question these statements (Alvarado 2007), and according to a recent study on urban insecurity in Mexico, 87% of Mexico City residents feel unsafe in their city, ranking Mexico City at the top of all other large urban agglomerations in the country (ICESI 2008). As a result, according to local opinion polls, security issues have become the central concern for most of the Mexico City residents—and policy makers. Therefore, it seems undeniable that "[t]he single-most relevant issue on the urban agenda today is fear" (Castillo 2008: 181). However, this development is not only a reflection of a perceived increase in crime. This situation is also closely related to serious problems regarding the Mexico City police forces, which include the lack of adequate human resources and training; high turnover rates; a lack of vocational ethics; deficient and outdated equipment; police corruption; the absence of a clear normative framework of action; and the direct participation of police agents in organized (and unorganized) crime, violence and human rights violations (Pansters and Castilo Berthier 2007; Piccato 2007; Silva 2007; Azaola 2006; Davis 2006; Naval 2006; López-Montiel 2000; Martínez Murguía 1999). Though the local police institutions have increasingly attracted attention from NGO activists and academic scholars, who have accumulated substantial knowledge regarding the problems of the local public security apparatuses, detailed empirical analysis of the daily encounters between police and the residents of Mexico City, which can be expected to be the principal setting where the abovementioned problems unfold, are still the exception.
Locally critical umklapp scattering and holography

description: Efficient momentum relaxation through umklapp scattering, leading to a power law in temperature d.c. resistivity, requires a significant low energy spectral weight at finite momentum. One way to achieve this is via a Fermi surface structure, leading to the well-known relaxation rate Gamma ~ T^2. We observe that local criticality, in which energies scale but momenta do not, provides a distinct route to efficient umklapp scattering. We show that umklapp scattering by an ionic lattice in a locally critical theory leads to Gamma ~ T^(2Δ(k_L)). Here Δ(k_L) \geq 0 is the dimension of the (irrelevant or marginal) charge density operator J^t(w,k_L) in the locally critical theory, at the lattice momentum k_L. We illustrate this result with an explicit computation in locally critical theories described holographically via Einstein-Maxwell theory in Anti-de Sitter spacetime. We furthermore show that scattering by random impurities in these locally critical theories gives a universal Gamma ~ 1/log(1/T)

Approaches to coda /s/ in Ecuadorian Spanish

/s/-voicing

dialectology

description: Ecuadorian Spanish displays significant regional variation affecting the realization of coda /s/. Within the highlands of Ecuador, the pronunciation of coda /s/ as [z] occupies different phonological environments depending on the subregion: While in the far north and south [z] is only found preceding voiced consonants, central and central-southern varieties display [z] in more environments, namely word-final prevocalic and prefix-final environments, which makes them unique in the Spanish-speaking world. In this investigation, I review the main studies that have focused on the description and analysis of coda /s/ voicing in Ecuadorian Spanish (Lipski, 1989 and Bradley & Delforge, 2006) and combine their insights with those of other studies (Muñiz Cachón & Cuevas Alonso, 2012, Navarro Tomás, 1968) which have explored the sonority of preconsonantal /s/. Stemming from this exploration, I present a conciliatory solution to the problem of /s/-voicing. I modify Lipski’s formal analysis to include a voice-neutral [S] that appears in pre-consonantal position, which resonates with the findings by Muñiz Cachón and Cuevas Alonso (2012) and the observations by Navarro Tomás (1968), both of which show that pre-consonantal /s/ in Spanish has gradient voicing.

description: We present the results of our UBVRI CCD photometry for the second brightest supernova of 2009, SN 2009nr, discovered during a sky survey with the telescopes of the MASTER robotic network. Its light and color curves and bolometric light curves have been constructed. The light-curve parameters and the maximum luminosity have been determined. SN 2009nr is shown to be similar in light-curve shape and maximum luminosity to SN 1991T, which is the prototype of the class of supernovae Ia with an enhanced luminosity. SN 2009nr exploded far from the center of the spiral galaxy UGC 8255 and most likely belongs to its old halo population. We hypothesize that this explosion is a consequence of the merger of white dwarfs.
Living and immortal polymerization of cyclic esters with a dinuclear indium catalyst
Creators: name: Xu, Cuiling
Publisher: name: University of British Columbia

description: The dinuclear indium catalyst [(NNO)InCl]₂(μ-OEt)(μ-Cl) (30), previously reported to be highly active and living in the ring-opening polymerization (ROP) of lactide (LA), was synthesized via a previously published procedure and is studied to be active for the ROP of β-butyrolactone (BBL), ε-caprolactone (CL) and allyl-β-butyrolactone (fBL). A series of diblock copolymers PLLA-b-PDLLA were synthesized for the first time and their thermal properties were studied. A series of triblock copolymers PLLA-b-PDLLA-b-PLLA/PDLA were synthesized for the first time. Studies on the polymerization of BBL by 30 reveal that it is highly solvent dependent and the rate is first order in BBL and catalyst concentration. The activation parameters were obtained from an Eyring plot. The polymerization is controlled, providing PHB with molecular weights in agreement to theoretical values up to 300 kDa in narrow distribution. Triblock copolymers PLLA-b-PHB-b-PDLA were synthesized via the sequential addition technique. Polymerization of CL by 30 showed an unusual slower rate than LA. Copolymers of allyl-β-butyrolactone with LA and BBL were made, supporting the feasibility of incorporating functionality into pendent groups of polyesters with this catalyst. The catalyst 30 is capable of immortal polymerization of LA and BBL with high loading of monomers and alcohols ([BBL]:[30]:[ROH] = 10000:1:100), providing polymers with molecular weights in well agreement with calculations inverse to the total amount of 30 and alcohols. The tacticity of polymers was not affected by the addition of ethanol. Poly(ethylene glycol) monomethyl ethers with molecular weights of 350 Da and 5000 Da were used as chain transfer agent to synthesize PEG and polyester block copolymers via iROP for the first time. Nanoparticles of PEG₁₁₄-b-PLLA₂₀₀ and PEG₁₁₄-b-PLLA₁₀₅ were made through nanoprecipitation and thin film rehydration/dialysis methods.

description: The province of Turkestan - modern-day Central Asia -, a Russian military colony since 1865-1875, truly entered WWI in 1916, when Tsar Nicholas II and his military staff decided, on 7 July (Gregorian calendar), to conscript a new labour force from the Muslims of Central Asia, who had not been drafted before, to serve in the rear of the Russian army. The imperial decree triggered uprisings over the region: the revolts lasted several weeks in the sedentary parts of the region and several months in the nomadic areas (especially in the south, in Semirechie). The consequences were drastic and put the province in a catastrophic situation, on the eve of the October revolution, and later the civil war.

Recent research has shown that the decision of going to war cannot be explained by short-term effects of media pressure. The media impact on foreign policy and military action is rather to be seen in long-term effects described by some historians within the epistemological and methodological framework of media theory.

A new approach to the results of Kövari, Sós, and Turán concerning rectangle-free subsets of the grid

description: For positive integers $m$ and $n$, define $f(m,n)$ to be the smallest integer such that any subset $A$ of the $m \times n$ integer grid with $|A| \geq f(m,n)$ contains a rectangle; that is, there are $x\in [m]$ and $y \in [n]$ and $d_{1},d_{2} \in \mathbb{Z}^{+}$ such that all four points $(x,y)$, $(x+d_{1},y)$, $(x,y+d_{2})$, and $(x+d_{1},y+d_{2})$ are contained in $A$. In \cite{kovarisosturan}, Kövari, Sós, and Turán showed that $\dlim_{k \to \infty}\dfrac{f(k,k)}{k^{3/2}} = 1$. They also showed that whenever $p$ is a prime number, $f(p^{2},p^{2}+p) = p^{2}(p+1)+1$. We recover their asymptotic result and strengthen the second, providing cleaner proofs which exploit a connection to projective planes, first noticed by Mendelsohn in \cite{mendelsohn87}. We also provide an explicit lower bound for $f(k,k)$ which holds for all $k$.

An exploration of neuter determiner 'lo' and 'lo que' constructions in Spanish
Creators: name: Levinstein Rodriguez, Andrea
Publisher: name: University of Calgary
Year: 2022
Subjects: Spanish
neuter 'lo'
neuter pronouns
nominal structure
syntax

description: This paper presents an exploratory overview of the syntactic properties of ‘lo’, a polysemic definite determiner that is standardly characterized as having a ‘neuter’ grammatical gender. I argue that ‘lo’ is better characterized as a referential pronoun lacking φ features, which refers to non-individuated entities. In addition to this referential ‘lo’, and following Zulaica Hernandez (2018), I argue that there is a non-referential, expletive ‘lo’, which relates a possible world to a predicate which may contain morphologically expressed φ features. However, the distribution and referentiality of ‘lo’ in ‘lo que’ constructions (prepositional clauses where ‘lo’ can be external or internal to the CP; see Plann, 1980) indicate that whether ‘lo’ is referential or expletive is not a matter of syntactic position, contrary to Zulaica Hernandez (2018). Referential ‘lo’ stands in contrast with most structurally defective pronouns, such as impersonal pronouns and expletives, in that it is a definite pronoun with a specific referent. This goes against the standard assumption that a nominal phrase that has properties associated with ‘higher’ layers of structure, such as definiteness (associated with DP), must therefore also have ‘lower’ layers like NumP and nP. Although this paper does not present a solution, it does point out that standard theory cannot account for it and argues for the need to continue developing our understanding of nominal structure.
Democracy, Veto Players and Integration in Mercosur

Democracy

description: It is expected that political and institutional variables can facilitate, in a large or a small way, the process of integration among the countries members of Mercosul, once its structure and mechanisms of decision-making can interfere in the approval or not of fundamental measures to the process of integration considered. In this sense, this article has two aims: first, considering the institutional arrangement currently in use, it tries to investigate main questions of the institutional analysis of Mercosur, such as: who are the veto players capable to veto the proposals to change the status quo? Who controls the agenda of these proposals? And what are the positions of these veto players face each other? Considering also the political and economic conditions of the country -- members of Mercosur, it analyses their forms of democracy, discussing the importance of the role of institutional and collective agents with power veto, attempting to verify the levels of difficulties imposed to the deepening of the process of regional integration in the Mercosul by each country. The analysis described has to take into account the desired levels of regional integration, once with deeper process of integration we will have more economic sectors involved, which, in its turn, if harmed, it will tend to demand their representations with power veto. Second, using a PROBIT Model, we conclude that more veto players, in more democratic regimes, generated difficulties for the regional process of integration in Mercosur, considering the possibility of integration between Brazil and the others members.
On the syntax of Mandarin sentence-final particles: a neo-performative analysis

Subjects: Mandarin sentence-final particles
interactional structure

description: Mandarin sentence-final particles have been analyzed uniformly as sentence-final complementizers by a group of researchers (Paul & Pan, 2017; Pan, 2019). However, in the present paper, I draw evidence from co-occurring sentence-final particles to demonstrate that in Mandarin, sentence-final particles must co-occur in a fixed order. This observation casts doubts on the assumption that these particles are complementizers because treating them as complementizers does not explain why they appear in a fixed order. Following Wiltschko (2020), I propose that these particles belong to different categories of the interactional structure. I focus my discussion on three representative particles, namely, ne 呢 , me 么 and ha 哈 . An analysis that assumes an interactional structure above CP can account for some poorly understood co-occurrence restrictions among these particles.

description: In today's business environment, the intense growth in competition and substantial changes have significantly increased the importance of customer-related constructs, such as consumer satisfaction, quality of service, and consumer loyalty, enforcing firms to implement clientfocused strategies. These aspects are particularly important for the competitiveness in industries where exchanges are complex, and clients are involved in the decision-making process, such as banks and microfinance institutions. This study aims to demonstrate the importance and complexity of consumer satisfaction in the service sector and specifically in the microfinance sector through a critical review of conceptual and empirical literature. Consumer satisfaction has been and continues to be one of the main marketing research area in the academic and managerial level internationally, whilst is still understudied in the context of Albanian economy in general and in the microfinance sector especially. The study aims to fulfill these theoretical and practical gaps and provides some important findings for managers and marketers of microfinance institutions in Albania.

description: We study the addition of quantum fermionic impurities to the N=6 supersymmetric Chern-Simons-matter theories in 2+1 spacetime dimensions. The impurities are introduced by means of Wilson loops in the antisymmetric representation of the gauge group. In a holographic setup, the system is represented by considering D6-branes probing the AdS_4 x CP^3 background of type IIA supergravity. We study the thermodynamic properties of the system and show how a Kondo lattice model with holographic dimers can be constructed. By computing the Kaluza-Klein fluctuation modes of the probe brane we determine the complete spectrum of dimensions of the impurity operators. A very rich structure is found, depending both on the Kaluza-Klein quantum numbers and on the filling fraction of the impurities.

description: The Belgian situation was unique in the sense that military losses were relatively limited compared to neighbouring countries due to the wait-and-see strategy pursued by King Albert I and a less successful mobilisation of the army in the first weeks of the conflict. The invasion and occupation of its territory led to significant civilian losses, which gave rise to a specific form of commemoration. About 40,000 Belgian soldiers died during the Great War; one-third due to illness. 8,756 civilians died, 6,453 during the first weeks of the invasion. Demographers add 78,665 deaths due to a higher mortality during the occupation.

Brazil and the Transatlantic Community in the Wake of the Global Crisis

Subjects: Latin Americans

description: In all, incorporating Brazil on its terms into established institutions of global governance will be challenging, but also worth the effort. The U.S. and the global North are well advised in the short-run to encourage the participation of Brazil in the various ad hoc global gatherings (e.g., the G-20 group) dealing with the financial crisis. For the long-run, the goal should be to integrate Brazil as a partner into reformed multilateral institutions (in finance, trade, and regulation) as a means of assuring more stable global growth on the basis of more inclusive global management. To understand the reasoning behind this recommendation, it is well to consider three separate issues: 1) the areas of common interests in foreign economic policy between Brazil and the transatlantic community; 2) the roots of Brazil's traditional divergences with the North; and 3) the domestic dynamics in Brazil that are leading to a change in its world view. These issues are considered in turn in this paper, followed by recommendations on how to incorporate Brazil more effectively into a transatlantic partnership.

description: Complementary to finding good general word embeddings, an important question for representation learning is to find dynamic word embeddings, for example, across time or domain. Current methods do not offer a way to use or predict information on structure between sub-corpora, time or domain and dynamic embeddings can only be compared after post-alignment. We propose novel word embedding methods that provide general word representations for the whole corpus, domain- specific representations for each sub-corpus, sub-corpus structure, and embedding alignment simultaneously. We present an empirical evaluation on New York Times articles and two English Wikipedia datasets with articles on science and philosophy. Our method, called Word2Vec with Structure Prediction (W2VPred), provides better performance than baselines in terms of the general analogy tests, domain-specific analogy tests, and multiple specific word embedding evaluations as well as structure prediction performance when no structure is given a priori. As a use case in the field of Digital Humanities we demonstrate how to raise novel research questions for high literature from the German Text Archive.

description: We, the editors, are pleased to present the thirty-second volume of the Calgary Working Papers in Linguistics (CWPL). CWPL is a publication affiliated with the School of Languages, Linguistics, Literatures and Cultures (SLLLC) at the University of Calgary, focusing on recent and ongoing work in linguistics and related disciplines by researchers affiliated with the University of Calgary. This and all previous volumes of CWPL since Volume 1 (originally published in print in 1975) are digitally stored in PRISM: The University of Calgary Digital Repository and can be accessed at: http://dspace.ucalgary.ca/handle/1880/. Before further discussing the papers in this volume, we would like to take this opportunity to acknowledge that the University of Calgary and city of Calgary, called Mohkinstsis in Blackfoot, exists within the traditional territories of the people of the Treaty 7 region in Southern Alberta, which includes the Blackfoot Confederacy (comprising the Siksika, Piikani, and Kainai First Nations), the Tsuut’ina First Nation, and the Stoney Nakoda (including the Chiniki, Bearspaw, and Wesley First Nations). The city of Calgary is also home to members of Métis Nation of Alberta, Region 3. Each paper submitted to Volume 32 has been reviewed and edited by two editors, all graduate students of linguistics at the University of Calgary. It should be noted that the papers published in CWPL represent works in progress and should not be considered as final or definitive papers. Therefore, publication in CWPL does not preclude submission of further revisions of the same papers to another journal or publication. Volume 32 contains three papers from both undergraduate and graduate students at the SLLLC. These papers explore topics in phonology, dialectology, nominal syntax, and particle syntax. The languages featured in this volume include Spanish and Mandarin Chinese. Finally, we thank and express our most sincere gratitude to all contributors, editors, and advisors and supervisors of those contributors and editors for their time, effort, and patience in their participation in the editing and publishing process of this volume. This continuation of CWPL’s longstanding tradition at the University of Calgary would be impossible without you and your work.

Economics

description: The majority of the literature considers that the establishment of stable institutions, providing better levels of security of property rights, is the key-factor to economic growth, taking into account the creation of favorable conditions to new investments and technological developments, especially considering an environment of globalization. In this sense, these "good institutions," or the so-called good governance, are closely related to the maintenance of the status quo, that is, the permanence of political and economic stabilities. On the other hand, economic growth requires, in a large way, political and economic changes to allow reforms, to make it possible. We verify, using statistical methods as Ordinary Least Squares (OLS), Least Square in Two-Stages (2QLS), Generalized Method of Moments (GMM), among others, that, despite the relevance of variables associated with good governance, the Brazilian economic growth is related negatively with the large numbers of veto players (agents with power veto) and the same happened to South American and East Asian countries. In some cases, the income growth rate is negatively related to the tenure of the veto players and their drop rate from the government basis. Thus, the weaker capacity to veto political and economic changes were associated to better economic growth rates, which does not mean one must not have institutional stability, but points out that the capacity to change the status quo is fundamental to generate conditions to economic growth in developing countries.
Interaction of a highly magnetized impulsive relativistic flow with an external medium

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Important astrophysical sources, such as gamma-ray bursts (GRBs) or tidal disruption events, are impulsive -- strongly varying with time. These outflows are likely highly magnetized near the central source, but their interaction with the external medium is not yet fully understood. Here I consider the combined impulsive magnetic acceleration of an initially highly magnetized shell of plasma and its deceleration by the external medium. I find four main dynamical regimes, that (for a given outflow) depend on the external density. (I) For small enough external densities the shell becomes kinetically dominated before it is significantly decelerated, thus reverting to the familiar unmagnetized "thin shell" case, which produces bright reverse shock emission that peaks well after the prompt GRB. (II) For larger external densities the shell remains highly magnetized and the reverse shock is strongly suppressed. It eventually transfers most of its energy through pdV work to the shocked external medium, whose afterglow emission peaks on a timescale similar to the prompt GRB duration. (III) For even larger external densities there is no initial impulsive acceleration phase. (IV) For the highest external densities the flow remains Newtonian.

description: The outbreak of war in 1914 interrupted a political crisis within the United Kingdom over the future of Ireland. Irish nationalists had been promised devolved government, which Ulster Unionists had pledged to resist by any means necessary. The failure to resolve this crisis caused first a wartime insurrection (the Easter Rising) and then a post-war revolution. During the central phase of this revolution (the Irish War of Independence) militant Irish separatists fought to establish an independent Irish Republic. But this conflict ended indecisively, and the final political settlement - a combination of dominion status and partition - led to civil war in both Northern Ireland and the Irish Free State.

In the present work, the emission properties of InGaN/GaN NWs grown by plasma-assisted molecular beam epitaxy are investigated in a comprehensive study combining ultraviolet-Raman and photoluminescence spectroscopy (PL) on vertical arrays, polarization-dependent PL on bundles of a few NWs, scanning transmission electron microscopy, energy-dispersive X-ray spectroscopy, and calculations of the band profiles. The roles of inhomogeneous In distribution and radial fields in the context of optical emission properties are addressed. The radial built-in fields are found to be modest, with a maximum surface band bending below 350 meV. On the other hand, variations in the local In content have been observed that give rise to potential fluctuations whose impact on the emission properties is shown to prevail over band-bending effects. Two luminescence bands with large positive and moderate negative polarization ratios of ≈+80% and ≤−60%, respectively, were observed. The red-shift in the luminescence is associated with In-rich inclusions in the NWs due to thermodynamic decomposition during growth. The negative polarization anisotropy is suggested to result from spontaneously formed superlattices in the In-rich regions of the NWs. The NWs show a preferred orthogonal absorption due to the dielectric boundary conditions and highlight the extreme sensitivity of these structures towards light polarization.

description: The present economic crisis is not a regional or local crisis, but a systemic one, which originated and expanded at the core of developed countries. In the 1980s, a debt crisis shook Latin America and Africa. Another one then hit Asia, Russia and again Latin America at the end of the 90s. Many countries had their trajectories momentarily interrupted, even though they were able to recover rapidly in tune with the global economy. In the current recession, it is the developed countries that are under the eye of the hurricane. Nevertheless, the impact on the emerging countries will be strong. Both for those that grew rapidly and benefited from a global environment marked by liquidity and low interest rates, a weak dollar and the rise of commodity prices; as well as for the more fragile countries, who will be, once again, the big losers. The crisis will not leave developing world unscathed. However, I argue that the current financial crisis will not sound the death knell for developing countries' recent economic success, as the debt crisis of the 1980s sounded for import substitution industrialization (lSI). They will suffer a strong downturn, but some of them could emerge stronger from the crisis.
On the relationship between cyclic and hierarchical three-species predator-prey systems and the two-species Lotka-Volterra model

description: We aim to clarify the relationship between interacting three-species models and the two-species Lotka-Volterra (LV) model. We utilize mean-field theory and Monte Carlo simulations on two-dimensional square lattices to explore the temporal evolution characteristics of two different interacting three-species predator-prey systems: (1) a cyclic rock-paper-scissors (RPS) model with conserved total particle number but strongly asymmetric reaction rates that lets the system evolve towards one corner of configuration space; (2) a hierarchical food chain where an additional intermediate species is inserted between the predator and prey in the LV model. For model variant (1), we demonstrate that the evolutionary properties of both minority species in the steady state of this stochastic spatial three-species corner RPS model are well approximated by the LV system, with its emerging characteristic features of localized population clustering, persistent oscillatory dynamics, correlated spatio-temporal patterns, and fitness enhancement through quenched spatial disorder in the predation rates. In contrast, we could not identify any regime where the hierarchical model (2) would reduce to the two-species LV system. In the presence of pair exchange processes, the system remains essentially well-mixed, and we generally find the Monte Carlo simulation results for the spatially extended model (2) to be consistent with the predictions from the corresponding mean-field rate equations. If spreading occurs only through nearest-neighbor hopping, small population clusters emerge; yet the requirement of an intermediate species cluster obviously disrupts spatio-temporal correlations between predator and prey, and correspondingly eliminates many of the intriguing fluctuation phenomena that characterize the stochastic spatial LV system.

description: This article examines how Switzerland has remembered and commemorated the First World War, during which the country maintained a state of neutrality but in which it was still manifoldly involved. It suggests a periodisation following from the historical and political uses made of the theme “Switzerland in the First World War” and shows how the state’s politics of history steered and functionalised the war narrative, especially in the period of the “''Geistige Landesverteidigung''” ("spiritual defence") (from the 1930s until roughly 1968). Besides the national narrative, which historical studies have never shirked, group-specific commemorative traditions are examined. Finally uncharted fields of research are mentioned as well as how urgently further research into the history of commemorating the absent war is needed.

subject: Education--Mathematics

description: The goal of Insurance companies, like that of any other financial institution, is to maximize their wealth. In doing so, there are different parameters they have to consider, such as premium rate, number of claim arrivals, size of claim arrival, etc. Moreover, they can invest their money in risk-free and risky asset to earn some income from those resources as well. This thesis discusses the application of Merton problem in insurance and risk and how to solve it. That is, we design a trading strategy for an insurance company such that its utility is maximized over a given time horizon. We use General Compound Hawkes Process to model the insurance’s risk and use the corresponding diffusion approximation to approximate the risk using a diffusion process. Then, we proceed with solving the problem by Hamilton- Jacobi-Bellman equation. Finally, we show some simulation results based on the calibration on data from insurance companies in Germany and their interpretations.

description: Tourism is a growing sector in the last year especially in developing countries. Tourism provide optimal conditions for economic growth and employment. Tourism is an increasingly important source of revenue and driver of growth in many countries in south-eastern Europe (SEE). Receipts from international tourist arrivals account for more than 10 per cent of GDP in several countries in SEE, with a substantial upward trend in the past five years. In light of the security risks in other popular markets, SEE can expect to see further rises in tourism in the coming years, which would help consolidate the economic recovery under way in the region. However, a recent World Economic Forum report on competitiveness in the travel and tourism industry highlights important shortcomings associated with weak price competitiveness, a problematic business environment, inadequate infrastructure and low prioritization of tourism industry. Addressing these problems would help the SEE region come closer to achieving its full potential in this important industry. This paper aims to explore the competitiveness in SSE and how Albania must face it. It tries to identify the problems is SSE and Albania too; it explores the successful experiences in other European countries and identifies success strategy and success factors for tourism development. For this purpose, after a wide literature review, and a comparative analysis of South-eastern Europe countries, it has been conducted a considerable number of half structured interviews with experts of actual and former units in charge of main Hotels in Albania. The analysis identifies as main fields that require attention: the lack of large capital investiment in sector, the lack of a competitiveness analysis, poor marketing and promotion in tourism, poor business environment, complicated property situation in Albania, etc.

description: Sufficient, high quality data steward expertise and capacity in projects and institutes is one of the necessities for FAIR data management in life- sciences and personalised medicine research. In a ZonMw funded project of UMCG, UMCU, Radboudumc, Radboud University and DTL, supported by the relevant national stakeholders, we are working to make the data steward function concrete, to create consensus on the function and required competencies and to develop tailored education. The overall project aim is to professionalise the data steward function within the life-sciences domain, with a special focus on the implementation of the FAIR data principles. All documents related to this project can be found on the Zenodo Collection “Towards a community-endorsed data steward profession description for life-science research”. This publication contains the first project deliverable: a matrix, that may function as the basis for a common job description of a data steward that is broadly supported within the Dutch life-sciences community. In the next phase of the project, this matrix will be complemented by knowledge, skills and competencies of a data steward, which will be translated into concrete learning objectives. These in turn will be used to develop an education line and training material for data stewards (including a design for an eLearning module). Sustainable implementation and alignment with existing education will be ensured.

description: A higher than predicted rate of two leptons plus missing transverse energy events, reported at the summer HEP conferences, can originate from a decay of the Higgs boson into a $WW^{(*)}$ pair, a misjudgement of the rate of SM background processes or a statistical fluctuation. In this paper we discuss a way to resolve this three-fold ambiguity.
