description: We consider the production and scattering amplitudes of heavy mesons in a situation, where there are two closely spaced narrow resonances, which structure we refer to as a diresonance. Assuming strong overlapping of the resonances coupled to common channels, it is found, using the unitarity and analyticity constraints, that the production amplitudes in different channels should have similar behavior with energy. In particular the ratio of the coefficients for each pole contribution to the production amplitude is fixed at -1.

description: Bulk single-crystal relaxor-ferroelectrics, like Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT), are widely known for their large piezoelectricity. This is attributed to polarization rotation which is facilitated by the presence of various crystal symmetries for compositions near a morphotropic phase boundary (MPB). Relaxor-ferroelectric thin films, which are necessary for low-voltage applications, suffer a reduction in their piezoelectric response due to clamping by the passive substrate. To understand the microscopic behavior of this adverse phenomenon, we employ AC electric field driven in-operando synchrotron x-ray diffraction (XRD) on patterned device structures to investigate the piezoelectric domain behavior under an electric field for both a clamped (001) PMN-PT thin film on Si and a (001) PMN-PT membrane released from its substrate. In the clamped film, the substrate inhibits the field induced rhombohedral (R) to tetragonal (T) phase transition resulting in a reversible R to Monoclinic (M) transition with a reduced longitudinal piezoelectric coefficient d33 < 100 pm/V. Releasing the film from the substrate results in recovery of the R to T transition and results in a d33 > 1000 pm/V. Using diffraction with spatial mapping, we find that lateral constraints imposed by the boundary between active and inactive material also inhibits the R to T transition. Phase-field calculations on both clamped and released PMN-PT thin films simulate our experimental findings. Resolving the suppression of thin film piezoelectric response is critical to their application in piezo-driven technologies.

description: Il testo è una riflessione intensa e critica sulla condizione umana, intrecciando filosofia, antropologia e psicologia per esplorare la bestialità dell’uomo e il suo continuo tentativo di elevarsi al di sopra di essa. Partiamo con denuncia della falsa superiorità dell’umanità, che si illude di aver superato la propria natura animale mentre ne resta prigioniera.

Segue una decostruzione delle dicotomie filosofiche tra stoicismo ed epicureismo, mostrando che, al di là delle differenze apparenti, entrambi mirano alla liberazione dal turbamento e alla ricerca di un equilibrio interiore. Tuttavia, la riflessione si sposta rapidamente verso una critica feroce della degenerazione moderna di questi ideali, ridotti a strumenti di adattamento alla macchina economica e sociale.

L’analisi si estende al concetto di umanità e alla celebre frase attribuita al tal Terenzio (Homo sum, humani nihil a me alienum puto), rivelandone le implicazioni più oscure: l’uomo non è solo condivisione di debolezze e sofferenze, ma anche di potenzialità distruttive e contraddizioni irrisolte. L’umanità stessa diventa il pericolo, e il “mostro” non è un’entità esterna da accogliere, bensì un riflesso perturbante di ciò che si deve contenere e rifiutare per preservare l’essenza autentica dell’essere.

Infine, il testo sfocia in una visione e nell’immersione nel “Salone delle Ombre”, che suggerisce un luogo di sospensione, forse un’eco della coscienza collettiva o un limbo tra realtà e illusione. Il tutto è pervaso da un tono lirico e corrosivo, che non concede illusioni né facili risposte, ma spinge il lettore a confrontarsi con l’abisso interiore.

description: While ultrahigh-baud-rate optical signals are effective for extending the transmission distance of large capacity signals, they also reduce the number of wavelengths that can be arranged in a band because of their wider bandwidth. This reduces the flexibility of optical path configuration in reconfigurable optical add/drop multiplexing (ROADM) networks. In colorless, directionless and contentionless (CDC)-ROADM in particular, the effect reduces the add/drop ratio at a node. Multiband ROADM systems are an effective countermeasure for overcoming this issue, but they make the node configuration more complicated and its operation more difficult. In this paper, we analyze the challenges of C + L band CDC-ROADM and show that optical switch devices that operate over multiple bands are effective in meeting them. For this purpose, we built a C + L band CDC-ROADM node based on C + L band wavelength selective switches (WSSs) and multicast switches (MCSs) and confirmed its effectiveness experimentally. In particular, to simplify the node configuration, we propose a reduction in the number of optical amplifiers used for node loss compensation and experimentally verify its feasibility.

description: Dark matter (DM) annihilations in the Galaxy may produce high energy neutrinos, which can be detected by the neutrino telescopes, for example IceCube, ANTARES and Super-Kamiokande. The neutrinos can also arise from hadronic interaction between cosmic ray and atmosphere around the Earth, known as atmospheric neutrino. Current measurements on neutrino flux is consistent with theoretical prediction of atmospheric neutrino within the uncertainties. In this paper, by requiring that the DM annihilation neutrino flux is less than the current measurements, we obtain an upper bound on the cross section of dark matter annihilation $ < {σv} >$. Compared with previous investigations, we improve the bound by including DM substructure contributions. In our paper, two kinds of substructure effects are scrutinized. One is the substructure average contribution over all directions. The other is point source effect by single massive sub-halo. We found that the former can improve the bound by several times, while the latter can improve the bound by $ 10^1 \sim 10^4$ utilizing the excellent angular resolution of neutrino telescope IceCube. The exact improvement depends on the DM profile and the sub-halo concentration model. In some model, IceCube can achieve the sensitivity of $ < {σv} > \sim 10^{- 26} cm^3 s^{- 1} $.

description: The influence of zinc ions on the thermochromic properties of polycrystalline Cu$_{1-x}$Zn$_x$MoO$_4$ ($x$=0.10, 0.50, 0.90) solid solutions was studied by X-ray absorption spectroscopy at the Cu, Zn and Mo K-edges. Detailed structural information on the local environment of metal ions was obtained from the simultaneous analysis of EXAFS spectra measured at three metal absorption edges using the reverse Monte Carlo method. Thermochromic phase transition with the hysteretic behaviour between $α$ and $γ$ phases was observed in Cu$_{0.90}$Zn$_{0.10}$MoO$_4$ solid solution. It was found that the local environment of molybdenum ions is most susceptible to the substitution of copper for zinc and, upon cooling, transforms from tetrahedral MoO$_4$ to distorted octahedral MoO$_6$.

description: Data collected in Run II of the Fermilab Tevatron are searched for indications of new electroweak-scale physics. Rather than focusing on particular new physics scenarios, CDF data are analyzed for discrepancies with the standard model prediction. A model-independent approach (Vista) considers gross features of the data, and is sensitive to new large cross-section physics. Further sensitivity to new physics is provided by two additional algorithms: a Bump Hunter searches invariant mass distributions for "bumps" that could indicate resonant production of new particles; and the Sleuth procedure scans for data excesses at large summed transverse momentum. This combined global search for new physics in 2.0/fb of ppbar collisions at sqrt(s)=1.96 TeV reveals no indication of physics beyond the standard model.

The Iron Silk Road and the Iron Fist: Making Sense of the Military Coup D’État in Thailand
Creators: name: Schaffar, Wolfram
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2018

description: In May of 2014, the military of Thailand staged a coup and overthrew the democratically elected government of Prime Minister Yingluck Shinawatra. The political divisions in Thailand, which culminated in the coup, as well as the course of events leading to the coup, are difficult to explain via Thai domestic policy and the power relations between Thailand’s military, corporate, and civil entities. The divisions can be more clearly revealed when interpreted in the context of the large-scale Chinese project “One Belt, One Road”. This ambitious infrastructure project represents an important step in the rise of China to the position of the world’s biggest economic power and – drawing on world-systems theory – to the center of a new long accumulation cycle of the global economy. Against this backdrop, it will be argued that developments in Thailand can be interpreted historically as an example of the upheavals in the periphery of China, the new center. The establishment of an autocratic system is, however, not directly attributable to the influence of China, but results from the interplay of internal factors in Thailand.

The long-range interaction in massless (lambda Phi^4)_4 theory

description: Does massless (lambda Phi^4)_4 theory exhibit spontaneous symmetry breaking (SSB)? The raw 1-loop result implies that it does, but the "RG-improved" result implies the opposite. I argue that the appropriate "low-energy effective theory" is a nonlocal field theory involving an attractive, long-range interaction Phi^2(x) Phi^2(y)/z^4, where z=|x-y|. RG improvement then requires running couplings for both this interaction and the original pointlike interaction. A crude calculation in this framework yields SSB even after "RG improvement" and closely agrees with the raw 1-loop result.

The Institutions of Authoritarian Neoliberalism in Malaysia: A Critical Review of the Development Agendas Under the Regimes of Mahathir, Abdullah, and Najib
Creators: name: Juego, Bonn
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2018

description: After toppling the 61-year dominant Barisan Nasional through a historic election victory in May 2018, expectations are high for the new ruling government led by Mahathir Mohamad and the Pakatan Harapan to fulfil their promises for socio-economic reforms and regime change in Malaysia. But what have been the institutions of the prevailing regime that need to be reformed and changed? This article offers a critical review of the evolving development agendas since the 1990s of the successive governments of Mahathir Mohamad, Abdullah Badawi, and Najib Razak, each couched in different catchphrases: Wawasan 2020, Islam Hadhari, and 1Malaysia. A close reading of these programs suggests that their substance articulates two persistent logics: the ruling elite’s constant requirement for political stability enforced by a strong state; and, the need to adapt to the demands and opportunities of accumulation in specific phases of Malaysia’s capitalist development in the context of globalization. The analysis reveals the attempts at maintaining authoritarian neoliberalism, or a neoliberal economy embedded in an authoritarian polity, as the de facto social regime in contemporary Malaysia. By examining policy documents, speeches, and news reports, the article discloses how this regime had been enunciated or reified in public discourses, policies, and actions of the respective administrations.

National Human Rights Institutions, Extraterritorial Obligations and Hydropower in Southeast Asia: Implications of the Region’s Authoritarian Turn
Creators: name: Middleton, Carl
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2018

description: This article examines the role of National Human Rights Institutions (NHRIs) and transnational civil society in pursing Extraterritorial Obligation (ETO) cases in Southeast Asia as a means to investigate human rights threatened by cross-border investment projects. Two large hydropower dams under construction in Laos submitted to NHRIs from Thailand and Malaysia, namely the Xayaburi Dam and Don Sahong Dam, are detailed as case studies. The article argues that the emergence of ETOs in Southeast Asia, and its future potential, is dependent upon the collaborative relationship between the NHRIs and transnational civil society networks. Whilst NHRIs are in positions of political authority to investigate cases, civil society also enable cases through networking, research, and public advocacy. Further institutionalization of ETOs is significant to emerging regional and global agendas on business and human rights, including the UN Guiding Principles on Business and Human Rights that both the Thai and Malaysian governments have expressed commitment to. However, in Thailand and its neighboring countries where investments are located there has been an authoritarian turn. Reflecting this, there are weakening mandates of NHRIs and reduced civil and political freedoms upon which civil society depends that challenges the ability to investigate and pursue cases.

Statistical properties of avalanches via the c-record process

description: We study the statistics of avalanches, as a response to an applied force, undergone by a particle hopping on a one dimensional lattice where the pinning forces at each site are independent and identically distributed (I.I.D), each drawn from a continuous $f(x)$. The avalanches in this model correspond to the inter-record intervals in a modified record process of I.I.D variables, defined by a single parameter $c>0$. This parameter characterizes the record formation via the recursive process $R_k > R_{k-1}-c$, where $R_k$ denotes the value of the $k$-th record. We show that for $c>0$, if $f(x)$ decays slower than an exponential for large $x$, the record process is nonstationary as in the standard $c=0$ case. In contrast, if $f(x)$ has a faster than exponential tail, the record process becomes stationary and the avalanche size distribution $π(n)$ has a decay faster than $1/n^2$ for large $n$. The marginal case where $f(x)$ decays exponentially for large $x$ exhibits a phase transition from a non-stationary phase to a stationary phase as $c$ increases through a critical value $c_{\rm crit}$. Focusing on $f(x)=e^{-x}$ (with $x\ge 0$), we show that $c_{\rm crit}=1$ and for $c<1$, the record statistics is non-stationary. However, for $c>1$, the record statistics is stationary with avalanche size distribution $π(n)\sim n^{-1-λ(c)}$ for large $n$. Consequently, for $c>1$, the mean number of records up to $N$ steps grows algebraically $\sim N^{λ(c)}$ for large $N$. Remarkably, the exponent $λ(c)$ depends continously on $c$ for $c>1$ and is given by the unique positive root of $c=-\ln (1-λ)/λ$. We also unveil the presence of nontrivial correlations between avalanches in the stationary phase that resemble earthquake sequences.

We consider a sample of a large width W and analyze the evolution of the conductance, the shot noise, and the full statistics of the charge transfer with increasing length L, both at the Dirac point and at a finite gate voltage. The transfer matrix approach combined with the disorder perturbation theory and the renormalization group is used. We also discuss the crossover to the diffusive regime and construct a ``phase diagram'' of various transport regimes in graphene.

description: Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) was launched on May 22, 2018. It carries the Laser Ranging Interferometer (LRI) as a technology demonstrator that measures the inter-satellite range with nanometer precision using a laser-link between satellites. To maintain the laser-link between satellites, the LRI uses the beam steering method: a Fast Steering Mirror (FSM) is actuated to correct for misalignment between the incoming and outgoing laser beams. From the FSM commands, we can compute the inter-satellite pitch and yaw angles. These angles provide information about the spacecraft's relative orientation with respect to line-of-sight (LOS). We analyze LRI derived inter-satellite pointing angles for 2019 and 2020. Further, we present its comparison with the pointing angles derived from GRACE-FO SCA1B data, which represents the spacecraft attitude computed from star cameras and Inertial Measurement Unit (IMU) data using a Kalman filter. We discuss the correlations seen between the laser based attitude data and the spacecraft temperature variations. This analysis serves as the basis to explore the potential of this new attitude product obtained from the Differential Wavefront Sensing (DWS) control of a FSM.

description: We introduce `braidability' as a new symmetry for (infinite) sequences of noncommutative random variables related to representations of the braid group $B_\infty$. It provides an extension of exchangeability which is tied to the symmetric group $S_\infty$. Our key result is that braidability implies spreadability and thus conditional independence, according to the noncommutative extended de Finetti theorem (of C. Köstler). This endows the braid groups $B_n$ with a new intrinsic (quantum) probabilistic interpretation. We underline this interpretation by a braided extension of the Hewitt-Savage Zero-One Law. Furthermore we use the concept of product representations of endomorphisms (of R. Gohm) with respect to certain Galois type towers of fixed point algebras to show that braidability produces triangular towers of commuting squares and noncommutative Bernoulli shifts. As a specific case we study the left regular representation of $B_\infty$ and the irreducible subfactor with infinite Jones index in the non-hyperfinite $II_1$-factor $L(B_\infty)$ related to it. Our investigations reveal a new presentation of the braid group $B_\infty$, the `square root of free generator presentation' $F_\infty^{1/2}$. These new generators give rise to braidability while the squares of them yield a free family. Hence our results provide another facet of the strong connection between subfactors and free probability theory and we speculate about braidability as an extension of (amalgamated) freeness on the combinatorial level.

“Trust Me, I am the One Who Will Drain the Swamp”: An Interview With Walden Bello on Fascism in the Global South
Creators: name: Schaffar, Wolfram
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2018

description: Since the election of Narendra Modi in India in 2014 and Donald Trump in the USA in 2016, political analysts and commentators around the globe have increasingly used the concept of fascism to capture the rise of new right-wing authoritarianism in various countries. Activists and academics in Europe are much more reluctant to use the word fascism, for several reasons. One reason is that – because of the alarming associations which fascism evokes in German – the term was often instrumentalized, and used to discredit political opponents, without a sound theoretical analysis. There is also a big reluctance to transfer the term to countries outside Europe, especially to the countries in the South – because it would further relativize the concept. Walden Bello is a prominent voice who started using the concept of fascism since early 2017 for the new regime under Rodrigo Duterte in the Philippines. He repeated his analysis of Duterte as a “fascist original” and his regime as “creeping fascism” at the International Convention of Asia Scholars (ICAS) in July 2017 as well as in recent articles (Bello, 2017). In October 2017, Bello was among the founding members of a new group, the Laban ng Masa coalition to combat the “fascist” policy of Duterte (Villanueva, 2017). In his most recent paper in the Journal of Peasant Studies, he broadened his analysis and compared the rise of Fascism in Italy in the 1920s with the establishment of the New Order under Suharto in Indonesia in 1964/1965, Chile at times of the coup d’état in 1973, Thailand in 1976, and the Philippines today (Bello, 2018). With his articles and his political campaigns, he opened a new chapter of academic discussion and political activism on fascism in the South. Walden Bello is currently a professor of sociology at the State University of New York at Binghamton and senior research fellow at the Center for Southeast Asian Studies of Kyoto University in Japan. He served as a member of the House of Representatives of the Philippines from 2009 to 2015, during which he was chairman of the Committee on Overseas Workers Affairs. In our interview conducted in December 2017, we discussed theoretical problems in dealing with the concept of fascism as well as strategic challenges for political activism.

description: We study a simple quantum mechanical model of a spinning particle moving on a sphere in the presence of a magnetic field. The system has two ground states. As the magnetic field is varied, the ground states mix through a non-Abelian Berry phase. We show that this Berry phase is the path ordered exponential of the smooth SU(2) 't Hooft-Polyakov monopole. We further show that, by adjusting a potential on the sphere, the monopole becomes BPS and obeys the Bogomolnyi equations. For this choice of potential, it turns out that there is a hidden supersymmetry underlying the system and the Bogomolnyi equations are analogous to the tt* equations of Cecotti and Vafa. We conjecture that the Bogomolnyi equations also govern the Berry phase of N=(2,2) supersymmetric sigma models with other target spaces.

description: A radial velocity study by Donati et al. (2016) reported the detection of a close-in giant planet in a 4.93 d orbit around the ~2 Myr old weak-lined T Tauri star V830 Tau. Because of the stringent timescale constraints that a very young host star like V830 Tau would place on hot Jupiter formation models and inward migration mechanisms, independent confirmation of the planet's existence is needed but so far has not been obtained. We present new Chandra X-ray observations of V830 Tau. The Chandra observations in combination with previous XMM-Newton observations reveal strong variable X-ray emission with an X-ray luminosity spanning the range log Lx = 30.10 - 30.87 ergs/s. Chandra High Energy Transmission Grating (HETG) spectra show emission lines formed over a range of plasma temperatures from ~4 MK (Ne IX) to ~16 MK (S XV). At the separation of the reported planet (0.057 au) the X-ray flux is ~10$^{6}$ - 10$^{7}$ times greater than the Sun's X-ray flux at Jupiter. We provide estimates of the X-ray ionization and atmospheric heating rates at the planet's separation and identify areas of uncertainty that will need to be addressed in any future atmospheric models.

An analysis of prefixal perfectivization in contemporary standard Russian
Creators: name: Toops, Gary Howard
Publisher: name: University of British Columbia
Year: 2010

description: Prefixal perfectivization is the object of considerable discussion in present-day Russian aspectology. Accordingly, the first chapter of this thesis attempts to present as accurately and concisely as possible the diverse views concurrent today among scholars in the field of Russian aspectology with regard to prefixal perfectivization. In the second chapter the meanings of the Russian verbal prefixes are given, to the extent that they are discernible in conjunction with a large variety of verbs. The prefixal verbs given to illustrate each meaning of a prefix are cited from lexicological reference works. The prefixal perfectives are identified at the end of each section of prefix meanings in Chapter II. The meanings of verbs and verbal prefixes are examined in order to determine the system by which the occurrence of a particular prefix in conjunction with a basic verb can be predicted. In Chapter III a representative selection of prefixal verbs is classified according to the degree or nature of semantic motivation underlying their occurrence. Semantic motivation is understood as a correlation between the lexical meaning of a prefix and that of the verb base, which is considered to prompt the occurrence of a particular prefix over any other in certain instances. The discussion of explanations for the occurrence of aspect-formative prefixes is based on an analysis of the meanings of verbs and prefixes as well as the application of concepts held in present-day aspectology; An examination of polysemy serves further to determine the nature of prefixal perfectivization as a grammatical process. On the basis of the material described above, it is concluded that correlations between the lexical meanings of some verbs and prefixes may be the reason for the addition of a particular prefix to a given basic verb. At the same time, however, it is determined that prefixation is not consistently motivated by any semantic correlations.

description: Type 2 diabetes mellitus (T2DM) represents an increasing public health problem in Peru. This study aims to estimate the national economic burden of this disease for the public funder, the social security, and private sector insurers. Direct healthcare costs were estimated for a cohort of 45-to-75-year-old adults diagnosed with T2DM in 2019, over a 20-year period. Disease progression was modeled using PROSIT Models and literature, including acute and chronic microvascular and macrovascular complications. Three scenarios of glycemic control were considered: current levels of 35.8% of the population controlled (HbA1c < 7%) (S1); 100% controlled (S2) and; 100% uncontrolled (S3). The impact of diabetes prevalence on overall costs was evaluated in sensitivity analysis. Total national economic burden was estimated at $15,405,448,731; an annual average per patient of $2,158. Total costs would decrease to $12,853,113,596 (−16.6%) in S2 and increase to $16,828,713,495 (+9.2%) in S3. Treating patients with complications and risk factors could cost 6.5 times more, being stroke the complication with the highest impact. Up to a 67.6% increase in total costs was found when increasing T2DM prevalence. T2DM places a heavy burden on the Peruvian healthcare budget that will be even greater if poor glycemic control is maintained.

description: White dwarf stars composed of carbon, oxygen or heavier elements are expected to crystallize as they cool down below certain temperatures. Yet, simple arguments suggest that the helium white dwarf cores may not solidify, mostly because of zero-point oscillations of the helium ions that would dissolve the crystalline structure. We argue that the interior of the helium dwarfs may instead form a macroscopic quantum state in which the charged helium-4 nuclei are in a Bose-Einstein condensate, while the relativistic electrons form a neutralizing degenerate Fermi liquid. We discuss the electric charge screening, and the spectrum of this substance, showing that the bosonic long-wavelength fluctuations exhibit a mass gap. Hence, there is a suppression at low temperatures of the boson contribution to the specific heat -- the latter being dominated by the specific heat of the electrons near the Fermi surface. This state of matter may have observational signatures.

An Exploration of the Narratives of Young People Who Have Experienced Emotional Based School Avoidance
Creators: name: Tamlyn, Guy
Publisher: name: University of East London
Year: 2022

description: Emotional Based School Avoidance (EBSA) has been linked with negative outcomes for the young person, family, school and the wider community. EBSA is presented in the literature as a difficulty that can impact on an individual’s academic progress, social relationships and emotional wellbeing. There is limited research that has sought the views of young people with experience of EBSA, meaning the way that EBSA is understood, and the support put into place is often shaped by adult views. Previous research has tended to use structured interviews which may place limits on the voice of the young person and their description of the phenomenon. The current study used a narrative approach to hear the stories of two secondary school girls of Bengali heritage who had experience of EBSA. Guided interviews took place online and life story grids were used to support the data collection. Clandinin and Connelly’s (2000) Three-Dimensional Space framework was used to re-story the narratives, which provided insight into the multifaceted nature of EBSA and those involved. Member checks with each young person took place to check for accuracy, whilst also appearing to offer therapeutic benefit. The narratives were analysed inductively and deductively using narrative thematic analysis and themes and subthemes relating to individual, school, home and professional factors were identified. Key themes interpreted within the narratives included risk and protective factors of relationships with staff and peers in school; impact of cultural views; dealing with loss and separation at home; challenges associated with the learning environment; managing negative emotions and mental health; impact of homelearning on participants’ wellbeing and resilience; the importance of individual coping mechanisms; positive, yet minimal, professional engagement. Implications for professional practice were framed using Ecological Systems Theory, highlighting how EBSA is experienced and shaped by individuals in multiple systems around the young person. Suggestions for future research are outlined.

Ressourcenschonendes Bauen ist ein essenzieller Hebel, der schnellst-möglich bewegt werden muss – und zwar zielführend, in die richtige Richtung. Doch was ist die richtige Richtung? Im Dschungel von Gesetzen, Richtlinien, DIN-Normen, Initiativen und Informationen ist es für Planende nicht leicht, den Überblick zu erlangen. Wie lassen sich die wachsende Nachfrage nach primären Rohstoffen wie Sand, Kies, Schotter und Kalk bremsen und die mit der Rohstoffextraktion und Verarbeitung verbunden Umweltwirkungen reduzieren? Hier soll die Checkliste allen relevanten Akteuren im Baubereich eine wichtige Hilfestellung geben.
Zur globalen Ökonomie von digitalen Drogenmärkten

description: Seit der Eröffnung des ersten Marktplatzes im Jahre 2011 ist der Vertrieb von legalen wie illegalen Drogen in einem anonymisierten Bereich des Internets nicht mehr wegzudenken. Unabhängig vom Ort und ohne zeitliche Beschränkung haben User_innen Zugang zu zahlreichen Marktplätzen im Darknet und können dabei aus einer breiten Palette an psychoaktiven Substanzen wählen.
Dieser Beitrag widmet sich einer zentralen Widersprüchlichkeit bei der kriminellen Innovation namens Kryptomärkte. Zum einen unterstützen anonyme Drogenmärkte eine Drogenpolitik, die auf Schadensminimierung und Entkriminalisierung von Konsumierenden setzt – beispielsweise, indem auf anonymen Märken oft qualitativ hochwertige Drogen vertrieben werden und Kund_innen weniger Gewalterfahrungen ausgesetzt sind. Zum anderen ist die Distribution von Drogen auf Kryptomärkten von Selbstregulierung geprägt, über die sämtliche politischen, sozialen und wirtschaftlichen Probleme zu lösen sind. Die Regulierung des Drogenhandels über den Markt hat zur Folge, dass soziale Ungleichheiten reproduziert werden. Marginalisierte, technisch unerfahrene Konsumierende aus mittellosen Verhältnissen und mit einem problematischen Konsumverhalten können es sich schlicht nicht leisten, auf Kryptomärkten ihre Substanzen zu erwerben. Abschließend fragt der Beitrag nach möglichen Implikationen des neuen Phänomens für politische Entscheidungsträger_innen im Bereich der Drogenpolitik.

description: (Abridged) We examine the X-ray luminosity scaling relations of 31 nearby galaxy clusters from the Representative XMM-Newton Cluster Structure Survey (REXCESS). The objects are selected in X-ray luminosity only, optimally sampling the cluster luminosity function; temperatures range from 2 to 9 keV and there is no bias toward any particular morphological type. Pertinent values are extracted in an aperture corresponding to R_500, estimated using the tight correlation between Y_X and total mass. The data exhibit power law relations between bolometric X-ray luminosity and temperature, Y_X and total mass, all with slopes that are significantly steeper than self-similar expectations. We examine the causes for the steepening, finding that the primary driver appears to be a systematic variation of the gas content with mass. Scatter about the relations is dominated in all cases by the presence of cool cores. The natural logarithmic scatter about the raw X-ray luminosity-temperature relation is about 70%, and about the X-ray luminosity-Y_X relation it is 40%. Cool core and morphologically disturbed systems occupy distinct regions in the residual space with respect to the best fitting mean relation, the former lying systematically to the high luminosity side, the latter to the low luminosity side. Exclusion of the central regions serves to reduce the scatter by more than 50%. Using Y_X as a mass proxy, we derive a Malmquist bias corrected luminosity-mass relation and compare with previous determinations. Our results indicate that luminosity can be a reliable mass proxy with controllable scatter, which has important implications for upcoming all-sky cluster surveys, such as those to be undertaken with Planck and eROSITA, and ultimately for the use of clusters for cosmological purposes.

description: Over the years motor deficit in Parkinson's Disease (PD) patients was largely studied, however, no consistent pattern of relations between quantitative electroencephalography (qEEG) and motor scales emerged. There is a general lack of information on the relation between EEG changes and scales related to specific motor deficits. Therefore, the study aimed to investigate the relation between brain oscillatory activity alterations (EEG power bands) and most used PD-related motor deficit scales. A positive correlation was found between the freezing of the gait questionnaire (FOGQ) and delta spectral power band (rho=0.67; p=0.008), while a negative correlation with the same scale was observed in the alpha spectral power band (rho=-0.59, p=0.027). Additionally, motor scores measure by motor part of Unified Parkinson's Disease Rating Scale (UPDRS) correlated directly with theta (rho=0.55, p=0.040) and inversely with beta EEG power band (rho=-0.77, p=0.001). No significant correlation was found between spectral powers and Hoehn and Yahr (H&Y), BERG (Berg K. et. al. 1995), Modified Parkinson Activity Scale (MPAS), Six-Minute Walk Test (6MWT) and Timed Up and Go Test (TUG). In conclusion, our study supports the earlier findings suggesting a link between EEG slowing and motor decline, providing more insight into the relation between EEG alteration and deficits in different motor domains. These findings indicate that EEG assessment may be a useful biomarker for objective monitoring of progression and neurophysiological effect of rehabilitation approaches in PD's.
