description: The role of middle-income countries and the LDCs have been empowered through the South-South Cooperation (SSC) since 1955 when the Asia-African Conference was held in Bandung, Indonesia. The SSC itself uses the frame of triangular cooperation to achieve sustainable development goals and technical collaboration with its member states. At the beginning of 2020, the annual press statement of Indonesia’s Foreign Minister speech emphasized Indonesia’s principle on diplomacy that mutual benefit within international cooperation needs to be done by reinforcing the new paradigm of multilateralism – a collaborative strategic outlook. This article linked the new paradigm with the current context of the world’s economic polarisation and its unprecedented impacts that has made shifts towards middle-income and least-developing countries to be more resilient and cooperative amid the pandemic. With the new landscape of the global economy, Indonesia is now challenged to move forward and reinforce its partnerships in multilateralism amidst the fading global altruism and protectionism, hence this was contested during the G-20 Sherpas meeting. The document-based and internet-based research with qualitative analysis in this article also considers the recent development of conferences and meetings with the stakeholders in SSC within the period of Mrs. Retno Marsudi’s term as Indonesia’s foreign minister from 2014 until 2020. The article concludes the trajectories of Indonesia’s post-pandemic public diplomacy in SSC, the new role of Indonesia as the bridgebuilder in the post-pandemic cooperation norms to achieve the SDGs through cooperation in the G-20, and public diplomacy for the political influence and economic interdependence

description: X-ray resonant magnetic reflectivity (XRMR) allows for the simultaneous measurement of structural, optical and magnetooptic properties and depth profiles of a variety of thin film samples. However, a same-beamtime same-sample systematic quantitative comparison of the magnetic properties observed with XRMR and x-ray magnetic circular dichroism (XMCD) is still pending. Here, the XRMR results (Pt L$_{3}$ absorption edge) for the magnetic proximity effect in Pt deposited on the two different ferromagnetic materials Fe and Co$_{33}$Fe$_{67}$ are compared with quantitatively analyzed XMCD results. The obtained results are in very good quantitative agreement between the absorption-based (XMCD) and reflectivity-based (XRMR) techniques taking into account an ab initio calculated magnetooptic conversion factor for the XRMR analysis. Thus, it is shown that XRMR provides quantitative reliable spin depth profiles important for spintronic and spin caloritronic transport phenomena at this type of magnetic interfaces.

description: Introduction The purposes of this paper are: (1) to introduce the social capital paradigm; (2) to present evidence that social capital has an important role in poverty reduction; and (3) to suggest several policy prescriptions for building and using social capital to reduce poverty. The social capital paradigm includes social capital, networks, socio-emotional goods, attachment values, institutions, and power. Social capital is a person or group's sympathy for others. Social capital resides in sympathetic relationships that can be described using networks. One reason to value social capital is because it can produce economic benefits and if neglected, economic disadvantages. Another reason to value social capital is because it can be used to produce socio-emotional goods. Sometimes socio-emotional goods become embedded in objects. When this occurs, the meaning and value of the object change. The change in the value of an object produced by embedded socio-emotional goods is the object's attachment value. Individuals exchange both physical and socio-emotional goods. Institutions are the rules that order and give meaning to exchanges. Institutions with high attachment values are more likely to be observed than those whose compliance depends on economic incentives or threats. Finally, power, the ability to influence others, depends on one's resources, including one's social capital. In most personalized transactions, persons exchange both socio-emotional goods and physical goods and services. Moreover, the relative amounts of socio-emotional goods and physical goods and services exchanged will alter the levels and terms of trade when measured in physical units. Since one's ability to include socio-emotional goods in exchanges for physical goods and services depends on one's social capital, the terms and levels of exchange of physical goods and services will be influenced by the transacting party's social capital. Those with high levels of social capital will have advantages over those who lack social capital because they can exchange both socio-emotional goods and physical goods and services. Furthermore, since social capital alters the terms and levels of trade and the terms and levels of trade influence the distribution of incomes derived from trades, then social capital also has an important influence on the distribution of household income and poverty. Some evidence suggests that the distribution of social capital in networks and the distribution of household incomes are connected.

description: We study synchronization of a quantum van der Pol oscillator with a harmonic drive and demonstrate that quantum synchronization can be enhanced by performing continuous homodyne measurement on an additional bath linearly coupled to the oscillator and applying feedback control to the oscillator. The phase coherence of the oscillator is increased by reducing quantum fluctuations via the continuous measurement, whereas the measurement backaction inevitably induces fluctuations around the phase-locking point. We propose a simple feedback policy for suppressing measurement-induced fluctuations by adjusting the frequency of the harmonic drive, which results in enhancement of quantum synchronization. We further demonstrate that the maximum enhancement of quantum synchronization is achieved by performing quantum measurement on the quadrature angle at which the phase diffusion of the oscillator is the largest and the maximal information of the oscillator phase is extracted.

description: Polarization-resolved second-harmonic spectra are obtained from the resonant modes of a two-dimensional planar photonic crystal microcavity patterned in a free-standing InP slab. The photonic crystal microcavity is comprised of a single missing-hole defect in a hexagonal photonic crystal host formed with elliptically-shaped holes. The cavity supports two orthogonally-polarized resonant modes split by 60 wavenumbers. Sum-frequency data are reported from the nonlinear interaction of the two coherently excited modes, and the polarization dependence is explained in terms of the nonlinear susceptibility tensor of the host InP.

description: Rapid population growth challenges the ability of local government to keep pace with increasing and changing demand for public services. These challenges may be physical or organizational in nature. Physical challenges arise from the need to upgrade public infrastructure such as water and sewer service, roads, schools, and emergency services. Although installation of new infrastructure is always expensive, growth-related increases in the tax base provide new revenue for installation of new services. However, when slowing growth rates, againg infrastructure, and addition of expensive new services pressure local government to increase revenue from existing resources decision-makers may then seek to reduce per-capita costs by reorganizing the method or structure of providing community services.

description: We forecast constraints on the amplitude of matter clustering sigma_8(z) achievable with the combination of cluster weak lensing and number counts, in current and next-generation weak lensing surveys. We advocate an approach, analogous to galaxy-galaxy lensing, in which the observables in each redshift bin are the mean number counts and the mean weak lensing profile of clusters above a mass proxy threshold. The primary astrophysical nuisance parameter is the logarithmic scatter between the mass proxy and true mass near the threshold. For surveys similar to the Dark Energy Survey (DES), the Roman Space Telescope High Latitude Survey (HLS), and the Rubin Observatory Legacy Survey of Space and Time (LSST), we forecast aggregate precision on sigma_8 of 0.26%, 0.24%, and 0.10%, respectively, if the mass-observable scatter has an external prior better than 0.01. These constraints would be degraded by about 20% for a 0.05 prior on scatter in the case of DES or HLS and for a 0.016 prior for LSST. A one-month observing program with Roman Space Telescope targeting approximately 2500 massive clusters could achieve a 0.5% constraint on sigma_8(z=0.7) on its own, or a ~0.33% constraint in combination with the HLS. Realizing the constraining power of clusters requires accurate knowledge of the mass-observable relation and stringent control of systematics. We provide analytic approximations to our numerical results that allow easy scaling to other survey assumptions or other methods of cluster mass estimation.

description: Social capital is a resource increasingly recognized as having important economic and social consequences. Robison and Siles (1999) examined some of these consequences at the U.S. state level and this study extends their efforts. Their 1999 study found important connections between the distributions of social capital and the distributions of household incomes. This study asks if the relationships between social capital and household incomes discovered at the state level are also present at the community level.

description: This research evaluates the effects of a hypothetical land value tax as a smart growth policy to curtail urban sprawl in the mid-sized metropolitan areas of the Southeastern United States. The effectiveness of a hypothetical land value tax on moderating urban sprawl is determined by changes in demand for neighborhood open space, and its relationships with lot size and proximity to the central business district (CBD). Achieving this goal will (1) provide applied researchers with an empirical foundation from which the spatial dynamics of urban sprawl in local housing markets can be measured, and (2) provide policy makers, especially in the large and mid-sized metro areas of the Southeast, with an ex ante instrument through which alternative incentives targeting open space preservation can be evaluated. We estimate the effects of a hypothetical land value tax on urban sprawl gauged through the three metrics of demand for neighborhood open space, lot size, and proximity to the CBD by comparing the forecasted values of the demand for these goods under alternative land value taxation schemes. The first is a “regular property tax” when the tax rates on the assessed values of land and structures are identical. The second is a hypothetical “land value tax” that places more weight on the value of land than on the value of structures, holding annual total county tax revenue constant.

description: In 2006 the EU revised again its Generalised System of Preferences scheme which provides preferential access to developing country exports to the EU market. This paper examines the extent to which the 2006 revisions to the scheme improved market access opportunities for developing countries for agro-food exports where most of the tariff changes were concentrated. Changes in the percentage preferential margin, in the value of preferential trade and in the value of the preferential margin on agro-food imports between 2004 and 2006 from developing countries are calculated. The results show that while the 2006 revision saw only a slight increase in the average percentage preferential margin enjoyed by exporters, there has been a significant increase in the preferential trade. This was accompanied by changes in the ranking of beneficiaries, particularly under the main GSP scheme. Although the predominance of net-exporting emerging countries such as China, Brazil, Argentina, India and South Africa was maintained, some newcomers such as Thailand and Vietnam have now emerged as major GSP beneficiaries.

description: Local three- and four-point correlators yield important insight into strongly correlated systems and have many applications. However, the nonperturbative, accurate computation of multipoint correlators is challenging, particularly in the real-frequency domain for systems at low temperatures. In the accompanying paper, we introduce generalized spectral representations for multipoint correlators. Here, we develop a numerical renormalization group (NRG) approach, capable of efficiently evaluating these spectral representations, to compute local three- and four-point correlators of quantum impurity models. The key objects in our scheme are partial spectral functions, encoding the system's dynamical information. Their computation via NRG allows us to simultaneously resolve various multiparticle excitations down to the lowest energies. By subsequently convolving the partial spectral functions with appropriate kernels, we obtain multipoint correlators in the imaginary-frequency Matsubara, the real-frequency zero-temperature, and the real-frequency Keldysh formalisms. We present exemplary results for the connected four-point correlators of the Anderson impurity model, and for resonant inelastic x-ray scattering (RIXS) spectra of related impurity models. Our method can treat temperatures and frequencies -- imaginary or real -- of all magnitudes, from large to arbitrarily small ones.

description: This paper develops an environmental performance index by applying the benefit of the doubt weighting and the Malmquist index concepts using Kuosmanen and Kortelainen’s approaches. The main difference between these approaches and other methods is that environmental performance is based on the definition of the eco-efficiency as the ratio of economic value added to the environmental damage index. The overall environmental performance index is also decomposed into two components representing changes due to technological progress (or regress) and due to changes in relative eco-efficiency. The dynamic environmental performance analysis is applied to 15 European agricultures from 1990 to 2004. Model results show that technical progress mostly explain overall environmental performance growth, while relative eco-efficiency changes have been minor for most European agricultures for the sample period.

description: Innovation is critical to the survival of agricultural businesses in the U.S. yet few universities have classes in their curricula that focus on innovation and innovation management. Innovation includes developing new processes and concepts and taking products based on those ideas to market. By its nature, innovation generally involves technical components, market assessment, business analysis, and implementation strategies that include marketing campaigns to a target market. As a result, if innovation is going to be experientially taught to students, the class will likely need to include concepts from multiple disciplines. The objectives of this paper are to present an outline of capstone/senior design classes designed to cause students to learn innovation by participating in interdisciplinary teams working with real companies on the development of new product innovation.

A rice-productivity index for each country is constructed, and a model linking the productivity gap with policy distortions is presented. After controlling for the differences in infrastructure, openness, and human capital, this article shows that high subsidies and protection in developed countries combined with taxation of rice farming in poor countries have widened the gap in rice productivity between rich and poor rice countries.

description: Progress in performing angle-resolved photoemission spectroscopy (ARPES) with high spatial resolution in the order of 1~$μ$m or less (nanoARPES) has opened the possibility to map the spectral function of solids on this tiny scale and thereby obtain detailed information on the materials' \emph{local} electronic band structure and many-body interactions. Recently, nanoARPES has been used to study simple electronic devices, based on two-dimensional materials, with the possibility of tuning the carrier type and density by field effect-gating, and while passing a current through the device. It was demonstrated that nanoARPES can detect possible changes in the materials' electronic structure in these situations and that it can map the local doping, conductance and mobility. This article reviews these first \emph{in operando} ARPES results on devices, discusses the resulting new insights, as well as the perspectives for future developments of the technique.

description: A gradual spin-state transition occurs in LaCoO3 around T~80-120 K, whose detailed nature remains controversial. We studied this transition by means of inelastic neutron scattering (INS), and found that with increasing temperature an excitation at ~0.6 meV appears, whose intensity increases with temperature, following the bulk magnetization. Within a model including crystal field interaction and spin-orbit coupling we interpret this excitation as originating from a transition between thermally excited states located about 120 K above the ground state. We further discuss the nature of the magnetic excited state in terms of intermediate-spin (IS, S=1) vs. high-spin (HS, S=2) states. Since the g-factor obtained from the field dependence of the INS is g~3, the second interpretation looks more plausible.

description: Feedback from massive stars plays a key role in molecular cloud evolution. After the onset of star formation, the young stellar population is exposed by photoionization, winds, supernovae, and radiation pressure from massive stars. Recent observations of nearby galaxies have provided the evolutionary timeline between molecular clouds and exposed young stars, but the duration of the embedded phase of massive star formation is still ill-constrained. We measure how long massive stellar populations remain embedded within their natal cloud, by applying a statistical method to six nearby galaxies at 20-100 pc resolution, using CO, Spitzer 24$\rm\,μm$, and H$α$ emission as tracers of molecular clouds, embedded star formation, and exposed star formation, respectively. We find that the embedded phase (with CO and 24$\rm\,μm$ emission) lasts for $2{-}7$ Myr and constitutes $17{-}47\%$ of the cloud lifetime. During approximately the first half of this phase, the region is invisible in H$α$, making it heavily obscured. For the second half of this phase, the region also emits in H$α$ and is partially exposed. Once the cloud has been dispersed by feedback, 24$\rm\,μm$ emission no longer traces ongoing star formation, but remains detectable for another $2{-}9$ Myr through the emission from ambient CO-dark gas, tracing star formation that recently ended. The short duration of massive star formation suggests that pre-supernova feedback (photoionization and winds) is important in disrupting molecular clouds. The measured timescales do not show significant correlations with environmental properties (e.g. metallicity). Future JWST observations will enable these measurements routinely across the nearby galaxy population.

description: The screening of point charges in hydrogenated Si quantum dots ranging in diameter from 10 A to 26 A has been studied using first-principles density-functional methods. We find that the main contribution to the screening function originates from the electrostatic field set up by the polarization charges at the surface of the nanocrystals. This contribution is well described by a classical electrostatics model of dielectric screening.

Αποτελέσματα: Δεν βρέθηκαν μεταλλάξεις του υποδοχέα της LDL χοληστερόλης στο τυχαίο αυτό δείγμα πληθυσμού, στο οποίο περιμέναμε με βάση τη συχνότητα μεταλλάξεων στη καυκάσια φυλή να είναι 1 με 2 μεταλλάξεις στα 888 άτομα. Βρέθηκε μονάχα ένας πολυμορφισμός που οδηγεί στην παραγωγή του ίδιου αμινοξέος (σιωπηλή μετάλλαξη).
description: Cardiovascular disease is the main cause of death in the western societies. There are many factors that take part in athyrogenesis including high levels of cholesterol in the blood. A cause of high levels of cholesterol in the blood is Familial hypercholesterolemia (FH), an autosomal dominant disorder usually caused by mutations in the gene that codes for the low density lipoprotein receptor (LDLR), with an estimated population frequency of carriers of 1 in 500.Objectives: Searching for polymorphisms in the gene that codes for the LDL receptor in a random sample of 888 children between the age of 8 and 20. Materials and methods: Biochemical analysis took place in all 888 children. We measured the concentration of total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, ApoA, ApoB, Lp(a). Then we choose 20 of the 888 children, in which we performed PCR and sequencing in the exons 3 to 15, in order to find mutations in the LDLR gene Results: We didn’t fount any mutations in the LDL Receptor gene in the population we studied, even if we excepted to find 1 or 2 mutations among the 888 children we examine. We find one polymorphism that didn’t change the amino acid sequence. (Silent mutation).

description: 21 cm cosmology opens an observational window to previously unexplored cosmological epochs such as the Epoch of Reionization (EoR), the Cosmic Dawn and the Dark Ages using powerful radio interferometers such as the planned Square Kilometer Array (SKA). Among all the other applications which can potentially improve the understanding of standard cosmology, we study the promising opportunity given by measuring the weak gravitational lensing sourced by 21 cm radiation. We performed this study in two different cosmological epochs, at a typical EoR redshift and successively at a post-EoR redshift. We will show how the lensing signal can be reconstructed using a three dimensional optimal quadratic lensing estimator in Fourier space, using single frequency band or combining multiple frequency band measurements. To this purpose, we implemented a simulation pipeline capable of dealing with issues that can not be treated analytically. Considering the current SKA plans, we studied the performance of the quadratic estimator at typical EoR redshifts, for different survey strategies and comparing two thermal noise models for the SKA-Low array. The simulation we performed takes into account the beam of the telescope and the discreteness of visibility measurements. We found that an SKA-Low interferometer should obtain high-fidelity images of the underlying mass distribution in its phase 1 only if several bands are stacked together, covering a redshift range that goes from z=7 to z=11.5. The SKA-Low phase 2, modeled in order to improve the sensitivity of the instrument by almost an order of magnitude, should be capable of providing images with good quality even when the signal is detected within a single frequency band. Considering also the serious effect that foregrounds could have on this detections, we discussed the limits of these results and also the possibility provided by these models of measuring an accurate lensing power spectrum.

description: The many-body problem is usually approached from one of two perspectives: the first originates from an action and is based on Feynman diagrams, the second is centered around a Hamiltonian and deals with quantum states and operators. The connection between results obtained in either way is made through spectral (or Lehmann) representations, well known for two-point correlation functions. Here, we complete this picture by deriving generalized spectral representations for multipoint correlation functions that apply in all of the commonly used many-body frameworks: the imaginary-frequency Matsubara and the real-frequency zero-temperature and Keldysh formalisms. Our approach separates spectral from time-ordering properties and thereby elucidates the relation between the three formalisms. The spectral representations of multipoint correlation functions consist of partial spectral functions and convolution kernels. The former are formalism independent but system specific; the latter are system independent but formalism specific. Using a numerical renormalization group (NRG) method described in the accompanying paper, we present numerical results for selected quantum impurity models. We focus on the four-point vertex (effective interaction) obtained for the single-impurity Anderson model and for the dynamical mean-field theory (DMFT) solution of the one-band Hubbard model. In the Matsubara formalism, we analyze the evolution of the vertex down to very low temperatures and describe the crossover from strongly interacting particles to weakly interacting quasiparticles. In the Keldysh formalism, we first benchmark our results at weak and infinitely strong interaction and then reveal the rich real-frequency structure of the DMFT vertex in the coexistence regime of a metallic and insulating solution.

description: Five-dimensional black holes are studied in Lovelock gravity coupled to Hoffmann-Infeld non-linear electrodynamics. It is shown that some of these solutions present a double peak behavior of the temperature as a function of the horizon radius. This feature implies that the evaporation process, though drastic for a period, leads to an eternal black hole remnant. Moreover, the form of the caloric curve corresponds to the existence of a plateau in the evaporation rate, which implies that black holes of intermediate scales turn out to be unstable. The geometrical aspects, such as the absence of conical singularity, the structure of horizons, etc. are also discussed. In particular, solutions that are asymptotically AdS arise for special choices of the parameters, corresponding to charged solutions of five-dimensional Chern-Simons gravity.

description: Consider the cellular automata (CA) of $\mathbb{Z}^{2}$-action $Φ$ on the space of all doubly infinite sequences with values in a finite set $\mathbb{Z}_{r}$, $r \geq 2$ determined by cellular automata $T_{F[-k, k]}$ with an additive automaton rule $F(x_{n-k},...,x_{n+k})=\sum\limits_{i=-k}^{k}a_{i}x_{n+i}(mod r)$. It is investigated the concept of the measure theoretic directional entropy per unit of length in the direction $ω_{0}$. It is shown that $h_μ(T_{F[-k,k]}^{u})=uh_μ(T_{F[-k,k]})$, $h_μ(Φ^{u})=uh_μ(Φ)$ and $h_{\vec{v}}(Φ^{u})=uh_{\vec{v}}(Φ)$ for $\vec{v} \in \mathbb{Z}^{2}$ where $h$ is the measure-theoretic entropy.

description: Documents are largely stored and shared digitally. Yet, digital documents are still commonly signed using (copies of) handwritten signatures, which are sensitive to fraud. Though secure, cryptography-based signature solutions exist, they are hardly used due to usability issues. This paper proposes to use digital identity wallets for securely and intuitively signing digital documents with verified personal data. Using expert feedback, we implemented this vision in an interactive prototype. The prototype was assessed in a moderated usability test (N = 15) and a subsequent unmoderated remote usability test (N = 99). While participants generally expressed satisfaction with the system, they also misunderstood how to interpret the signature information displayed by the prototype. Specifically, signed documents were also trusted when the document was signed with irrelevant personal data of the signer. We conclude that such unwarranted trust forms a threat to usable digital signatures and requires attention by the usable security community.
A Speech Act Analysis of Selected Wall-Cartoons

description: Cartoons are drawings that are message-laden, whether or not they are comic. Thematic concerns in cartoons (economic recession, corruption, poverty, oppression, moral decadence, bad leadership, etc.) are conveyed via varied contextual structures including political, domestic and religious domains. Across genres, cartoons are veritable means of communication deployed by creative artists. This study is a speech act analysis of cartoons gathered from a school wall. A speech act analysis of the use of verbal and non-verbal communication (as in semiotics) investigates the pragmatic underpinnings for explaining “what gets said”, “how it is said” and “why it is said”. Two theoretical frameworks underpin this study: Bach and Harnish’s (1979) Speech Act Theory as well as Acheoah’s (2015) Pragma-crafting Theory. While the latter provides the study speech act taxonomy, the former facilitates the identification and explanation of the pragmatic nuances in verbal and non-verbal communication evident in the data. Conclusively, the study observes that: cartoons rely on both verbal and non-verbal communication; the messages in cartoons are conveyed via contextualization; the use of speech acts in cartoons is a reflection of the artist’s (henceforth “cartoonist”) pragmatics-driven communicative intentions; and cartoon messages are interpreted by exploring cartoonist-audience shared knowledge.

description: Comprehensive neuropsychological testing is impractical in a multidisciplinary ALS clinic. The Edinburgh Cognitive and Behavioral ALS Screen (ECAS) is a brief screen that includes an ALS-Specific Score (Language, Verbal Fluency, and Executive domains), an ALS Non-Specific Score (Memory and Visuospatial domains), and a Behavioral Screen completed by a caregiver.  It has been validated in the UK, demonstrating high sensitivity (85%) and specificity (85%) for cognitive dysfunction.

Objectives:  1) Assess the feasibility of performing the ECAS as a screen in a multidisciplinary ALS clinic; 2) Compare ECAS results from a US ALS clinic to UK data.

Discussion and Conclusions:  The ECAS can be administered in a multidisciplinary ALS clinic by individuals undergoing relatively brief training.  Cognitive abnormalities were found more frequently in the US clinic sample than in the published UK data, although the relative frequency of ALS-Specific abnormalities was similar.  The higher frequency in the US group may be due to different patient populations (clinic population vs. a registry population, different inclusion/exclusion criteria).  Behavioral changes were similar in the US and UK groups.  Further studies are warranted to establish true US normative data.

description: Using data from the 1999-2002 rounds of the continuous National Health and Nutrition Examination Survey (NHANES), the inter-relationships between food insecurity, diet quality and body mass index (BMI) were examined. The impact of smoking and alcohol consumption behaviors were also examined. The relationship between BMI and food insecurity was found to be sensitive to the specification of control variables, such as age, income, and race and ethnicity. Smoking was directly associated with lower BMI for both men and women; while alcohol consumption was directly associated with lower BMI only for men. Smoking negatively affected food insecurity and diet quality, as measured by the Healthy Eating Index (HEI). For women, these indirect effects were statistically significant and positive, but extremely small in magnitude compared to the direct effect. For both men and women, level of physical activity was found to be a much more important determinant of body weight than smoking, drinking, and food insecurity. For women, race had a more important impact on body weight than smoking or drinking.
