description: A representation of spatial infinity based in the properties of conformal geodesics is used to obtain asymptotic expansions of the gravitational field near the region where null infinity touches spatial infinity. These expansions show that generic time symmetric initial data with an analytic conformal metric at spatial infinity will give rise to developments with a certain type of logarithmic singularities at the points where null infinity and spatial infinity meet. These logarithmic singularities produce a non-smooth null infinity. The sources of the logarithmic singularities are traced back down to the initial data. It is shown that is the parts of the initial data responsible for the non-regular behaviour of the solutions are not present, then the initial data is static to a certain order. On the basis of these results it is conjectured that the only time symmetric data sets with developments having a smooth null infinity are those which are static in a neighbourhood of infinity. This conjecture generalises a previous conjecture regarding time symmetric, conformally flat data. The relation of these conjectures to Penrose's proposal for the description of the asymptotic gravitational field of isolated bodies is discussed.

Technology for the scalability of co-creation with students
Creators: name: Dollinger, Mollie
Publisher: name: La Trobe
Year: 2023

description: Student-staff co-creation is a growing topic in higher education research. Framed as a mechanism for universities to better modify and meets the needs and expectations of students, student co-creation has a wealth of potential benefits. However, with the expansion of research, many scholars have stumbled upon a similar limitation, the scalability of co-creation. This issue is due to co-creation currently occurring in face-to-face (f2f) interactions (e.g. pedagogical consultants). However, co-creation can also arise in online spaces, enabled by technology, that could allow for greater scalability. In this paper, three strategies supported with technology to enhance the scalability of co-creation will be discussed including, crowdsourcing, customisation and prosumer behaviour with relevant industry examples for each as well as suggestions for practice in higher education. The limitations, benefits, and new directions for research will further be discussed. It is the aim of the paper to provoke ideas on how co-creation can be made more accessible to all students.

description: This paper uses the well-known Oaxaca-Blinder decomposition technique to understand the determinants of wage-gaps between men and women, between urban and rural workers, and between those employed in the rural agricultural versus the rural non-agricultural sectors, for the 14 developing and transition economies in the RIGA-L dataset. The unexplained male-female wage gaps (i.e. the gaps that remain after controlling for a host of observable characteristics of the job and the worker) provide estimates of labor market discrimination against women that are consistent with prior estimates from other countries, and are generally similar in rural and urban areas. We argue that countries with large unexplained urban-rural gaps, such Tajikistan and Malawi, are those in which rural to urban migration is likely to persist even in face of high urban unemployment rates. Furthermore, we find that large unexplained wage gaps in favor of non-farm employment, versus paid labor in farming, exist in Tajikistan (53%), Ecuador (44%), Nepal (36%), Nicaragua (32%), and Nigeria (30%); these would then appear to be the countries for which a shift of existing workers, with their current attributes, from the farm to the non-farm sector would have the largest impact on rural incomes.

description: We theoretically analyze superradiant emission of light from a cold atomic gas, when mechanical effects of photon-atom interactions are considered. The atoms are confined within a standing-wave resonator and an atomic metastable dipolar transition couples to a cavity mode. The atomic dipole is incoherently pumped in the parameter regime that would correspond to stationary superradiance in absence of inhomogeneous broadening. Starting from the master equation for cavity field and atomic degrees of freedom we derive a mean-field model that allows us to determine a threshold temperature, above which thermal fluctuations suppress superradiant emission. We then analyze the dynamics of superradiant emission when the motion is described by a mean-field model. In the semiclassical regime and below the threshold temperature we observe that the emitted light can be either coherent or chaotic, depending on the incoherent pump rate. We then analyze superradiant emission from an ideal Bose gas at zero temperature when the superradiant decay rate $Λ$ is of the order of the recoil frequency $ω_R$. We show that the quantized exchange of mechanical energy between the atoms and the field gives rise to a threshold, $Λ_c$, below which superradiant emission is damped down to zero. When $Λ>Λ_c$ superradiant emission is accompanied by the formation of matter-wave gratings diffracting the emitted photons. The stability of these gratings depends on the incoherent pump rate $w$ with respect to a second threshold value $w_c$. For $w>w_c$ the gratings are stable and the system achieves stationary superradiance. Below this second threshold the coupled dynamics becomes chaotic. We characterize the dynamics across these two thresholds and show that the three phases we predict (incoherent, coherent, chaotic) can be revealed via the coherence properties of the light at the cavity output.

Antagonistic activity was assessed on agar medium in Petri dishes. The ability of the microorganisms to inhibit pathogen colony growth was estimated. Cladosporium sp., Clonostachys sp, Fusarium sambucinum, Fusarium sp. and bacteria did not significantly affect the growth of A. alternata and F. equiseti. Chaetomium globosum showed a significant inhibitory effect on the growth of A. alternata and Fusarium equiseti. Bjerkandera adusta had the highest antagonistic activity. During prolonged joint incubation, the colony of Bjerkandera adusta covered the entire space in the Petri dish, inhibiting the growth of A. alternata and F. equiseti

description: Self-compassion involves treating oneself with the same kindness, understanding, and forgiveness that one would typically offer a friend in times of suffering or adversity. While self-compassion has shown consistent benefits in research and therapy, including psychological and physical health benefits, some individuals practicing it may initially encounter adverse reactions known as “backdraft.” Backdraft has been theorized to be an inevitable part of healing and recovery from past hurts and trauma. However, empirical studies specifically examining backdraft experiences in the context of self-compassion are lacking. This commentary argues that integrating broader literature outside of self-compassion is crucial for advancing our understanding of the causes of backdraft and identifying practices to alleviate it. Specifically, ideas drawn from traditional Buddhist practices and phenomena conceptually similar to backdraft, such as fear of self-compassion from compassion-focused therapy and adverse effects of meditation practices used in mindfulness-based interventions, should be considered. This commentary concludes that there is an urgent need to establish a clear definition of backdraft. This may promote empirical investigations of the backdraft experiences arising from self-compassion interventions. Only through empirical research can we better understand this backdraft phenomenon, with the ultimate goal of reducing short- and long-term harm and improving the efficacy of self-compassion programs.
Urban Art far beyond counterculture
Creators: name: Augusto, Larissa
Publisher: name: CAP - Public Art Journal
Year: 2020

description: Urban art emerged as a counterculture movement based on social, political and economic criticism. To shape these criticisms, interventions are made around city centers and peripheries, in the most unusual places, such as bridges, sewers, abandoned places, train stations, house walls and top of buildings. Because it is done on the streets, the intervention suffers from the weather and can be changed and even covered by another artist. The artist, in turn, risks being arrested and having his art labeled as vandalism, as such art happens in non-legalized places. And so street art is defined as an ephemeral work, accessible to all people and only possible to be registered by photography.

description: This paper analyzes the household level impact of an increase in price of major tradable staple foods in a cross section of developing countries, using nationally representative household surveys. We find that, in the short term, poorer households and households with limited asset endowments and access to agricultural inputs will be hit the hardest by the price shock. Given the ample degree of heterogeneity among households and among the poor, the analysis emphasizes the importance of meaningful policy research to go beyond average impacts to look at how access to assets and inputs, livelihood strategies and other key household characteristics drive the magnitude and distribution of the effects of the price increases.

The deuterium-to-oxygen ratio in the interstellar medium
Creators: name: Hebrard, Guillaume

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Because the ionization balances for HI, OI, and DI are locked together by charge exchange, D/O is an important tracer for the value of the D/H ratio and for potential spatial variations in the ratio. As the DI and OI column densities are of similar orders of magnitude for a given sight line, comparisons of the two values will generally be less subject to systematic errors than comparisons of DI and HI, which differ by about five orders of magnitude. Moreover, D/O is additionally sensitive to astration, because as stars destroy deuterium, they should produce oxygen. We report here the results of a survey of D/O in the interstellar medium performed with FUSE. We also compare these results with those for D/N. Together with a few results from previous missions, the sample totals 24 lines of sight. The distances range from a few pc to ~2000 pc and log N(DI) from ~13 to ~16 (cm-2). The D/O ratio is constant in the local interstellar medium out to distances of ~150 pc and N(DI) ~ 1x10^15 cm-2, i.e. within the Local Bubble. In this region of the interstellar space, we find D/O = (3.84+/-0.16)x10^-2 (1 sigma in the mean). The homogeneity of the local D/O measurements shows that the spatial variations in the local D/H and O/H must be extremely small, if any. A comparison of the Local Bubble mean value with the few D/O measurements available for low metallicity quasar sight lines shows that the D/O ratio decreases with cosmic evolution, as expected. Beyond the Local Bubble we detected significant spatial variations in the value of D/O. This likely implies a variation in D/H, as O/H is known to not vary significantly over the distances covered in this study. Our dataset suggests a present-epoch deuterium abundance below 1x10^-5, i.e. lower than the value usually assumed, around 1.5x10^-5.

description: We present a novel UV freeze-in mechanism for enhancing the dark matter abundance in cosmologies where inflation is followed by an epoch dominated by a fluid stiffer than radiation. In such scenarios, even a small radiation abundance, produced for instance by instantaneous preheating effects, will eventually dominate the total energy density of the Universe without the need for a complete inflaton decay. For the sake of concreteness, we focus in non-oscillatory (NO) quintessential inflation models, albeit our treatment is rather general and can be extended to other scenarios. The high temperature of the initial thermal bath together with the absence of subsequent entropy injections into the Standard Model plasma translates into a highly-effective UV DM freeze-in. In particular, we find that, during kination, an enhancement in the DM abundance is generically obtained for any production cross-section not-decreasing with temperature.

description: We present the first thermal-infrared imaging photometry for several embedded sources in the OMC1 South cloud core in the Orion nebula, and propose that some of these drive optical Herbig-Haro jets emerging from the region. Thermal-infrared images at 8.8 and 11.7 micron obtained at Gemini South show a handful of sources in OMC1-S with no visual-wavelength counterparts, although a few can be seen in recent near-infrared data. For the three brightest mid-infrared sources, we also present 18.75 micron photometry obtained with the Keck telescope. The most prominent blueshifted outflows in the Orion nebula at visual wavelengths such as HH202, HH203/204, HH529, and HH269 all originate from OMC1-S. The brightest infrared source in OMC1-S at 11.7 micron is located at the base of the prominent jet that powers HH202 and is likely to be the sought-after driver of this outflow. The second brightest infrared source is located at the base of the HH529 jet. We consider the possibility that HH203/204 and HH269 trace parts of a single bent outflow from the third-brightest infrared source. While there may be some lingering ambiguity about which infrared stars drive specific jets, there is now a sufficient number of embedded sources to plausibly account for the multiple outflows from OMC1-S.

description: This article proposes a general pattern of rural development in which rises in per capita income are associated with a decline in the importance of agricultural production and a rise in the importance of non-agricultural income sources. Following the approach to examining Engel's Law, we use data from 15 developing countries and a merged data set to test whether such a pattern emerges. The analysis shows a strong, positive relationship between rising per capita income and the share of income earned from rural non-agricultural activities and a negative relationship between per capita income and agricultural production.

Three-body spin-orbit forces from chiral two-pion exchange
Creators: name: Kaiser, N.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Using chiral perturbation theory, we calculate the density-dependent spin-orbit coupling generated by the two-pion exchange three-nucleon interaction involving virtual $Δ$-isobar excitation. From the corresponding three-loop Hartree and Fock diagrams we obtain an isoscalar spin-orbit strength $F_{\rm so}(k_f)$ which amounts at nuclear matter saturation density to about half of the empirical value of $90 $MeVfm$^5$. The associated isovector spin-orbit strength $G_{\rm so}(k_f)$ comes out about a factor of 20 smaller. Interestingly, this three-body spin-orbit coupling is not a relativistic effect but independent of the nucleon mass $M$. Furthermore, we calculate the three-body spin-orbit coupling generated by two-pion exchange on the basis of the most general chiral $ππNN$-contact interaction. We find similar (numerical) results for the isoscalar and isovector spin-orbit strengths $F_{\rm so}(k_f)$ and $G_{\rm so}(k_f)$ with a strong dominance of the p-wave part of the $ππNN$-contact interaction and the Hartree contribution.

We show that its value inside virialised regions will be significantly larger than in the low-density background universe. The consideration of the inhomogeneous evolution of the universe is therefore essential for a correct comparison of extragalactic and solar system limits on, and observations of, possible time variation in $α$ and other constants. Time variation in $α$ in the cosmological background can give rise to no locally observable variations inside virialised overdensities like the one in which we live, explaining the discrepancy between astrophysical and geochemical observations.

description: Public space is a place of constant negotiation, a stage for the power struggle that establishes the limits of coexistence – rules and boundaries that do not always coincide with the ones that regulate private space. Since graffiti and street art are forms of artistic expression in public space, they contribute to that negotiation in distinct ways whether they are developed freely (and, in most cases, illegally), or as a response to institutional commissions – often made by public entities. The difference is especially evident in how power is exerted – from the spontaneous decision that arises from the artists themselves to the rules of the contest, or institutional commission, that are determined by political decision makers or representatives, according to the politics they wish to implement within their territories.

description: Our paper examines the causes and dynamics of the shift in the gender composition of migration, and more particularly, in the access of women to migration opportunities and decision making. We do this in the context of Albania, a natural laboratory for studying migration developments given that out-migration was practically eliminated from the end of WWII to the end of the 1980s. We use micro-level data from the Albania 2005 LSMS including migration histories for family members since migration began. Our analysis, based on discrete-time hazard models, shows an impressive expansion of female participation in international migration. Female migration, which we find to be strongly associated with education, wealth, and social capital, appears responsive to economic incentives and constraints. Yet, using unique data on the dependency of female migration to the household demographic structure as well as the sensitivity of female migration to household-level shocks, we show that it is the households themselves that are the decision-making agents behind this economic calculus and there is little to suggest that increased female migration signals the emergence of female agency.

description: Adding a pragma directive into the source code is arguably easier than rewriting it, for instance for loop unrolling. Moreover, if the application is maintained for multiple platforms, their difference in performance characteristics may require different code transformations. Code transformation directives allow replacing the directives depending on the platform, i.e. separation of code semantics and its performance optimization. In this paper, we explore the design space (syntax and semantics) of adding such directive into a future OpenMP specification. Using a prototype implementation in Clang, we demonstrate the usefulness of such directives on a few benchmarks.

description: The transformation of the intelligence ecosystem associated with the digital transformation represents a critical juncture for diversity and inclusion (D&I). We present a multidisciplinary perspective on digital transformation and D&I that demonstrates that, in the context of automated decision making, where algorithmic biases and the standardisation of thought represent new risks, neurodiversity initiatives become a cornerstone for advancing D&I. Based on interviews with neurodiversity experts, we identify innovative ways to efficiently configure an inclusive organisational design targeting neurodiversity by leveraging technologies. We identify several properties of technologies that support D&I in neurodiversity initiatives: the neutralisation of biases during interviews, the development of digital support for physical and mental well-being and the facilitation of different cognition modes. Finally, we critically discuss the risks and opportunities offered by various technologies in terms of performance evaluation, new forms of dominance, and design of a digital ecosystem for mental well-being.

description: In the light of an expanding rural non-farm (RNF) sector in developing rural economies, this paper explores the effects of this expansion within the household. Using rural Ghana as a case study this paper explores if the RNF economy allows for economies of diversification within farms; how input demands, agricultural-specific and shared, are transformed by the expansion of this sector; and if this expansion has measurable effects in overall household production efficiency. We first explore the characteristic of the intra-household linkages (technological and welfare driven) between the agricultural and RNF sectors both assuming perfectly working input and output markets, and assuming market failures, in particular missing labor and credit markets. We then try to measure the identified linkages by estimating a household level input distance function. This function is estimated consistently without making log-transformations as has been previously done in the literature. Our empirical analysis suggests that there are high levels of inefficiency in Ghanaian farms. Also, there are cost-complementarities between the RNF sector and the agricultural sector, particularly with food crops in which the poorest tend to specialize. The expansion of the RNF sector increases demand for most inputs including agricultural land. Finally, we show that smaller farms tend to be more efficient, and that RNF output is helping the farm household to become more efficient, but the latter result is not robust.

description: Lisbon - Portugal is considered one of the world capitals of urban art. The urban art (also known as street art) emerged around 5 decades ago in USA, specifically at Philadelphia and later at New York. It was also named as “graffiti” by young people as a claim of a communicative space in the city. The urban art supposes the transposition of places and non-places represented by the public space as the opposite of the house, the nest. It’s the place appropriation, as exposed in the image above that is a tile wall close to the Ladra fair (Feira da Ladra). That art represents the city reinterpretation, focusing in the main monuments with a mix of elements that promote a look development, the sensitive feeling.

description: This paper documents the main findings of a study on food insecurity and vulnerability in the Indian state of Orissa in support of promoting interventions for food security and livelihoods at state level. A similar study was undertaken in Himachal Pradesh, India. The paper analyses the main characteristics and causes of food insecurity and vulnerability. It seeks to identify who are vulnerable and food insecure and where they are, why they risk food insecurity and what options exist to reduce their vulnerability. Using the sustainable livelihoods framework and collecting qualitative and quantitative data from four selected districts, the paper looks at six livelihood groups, notably marginal and small scale farming households, labouring rural households, mining worker households, rural artisan households, fishing households and scheduled tribal households. Even though Orissa is virtually self-sufficient in food grains, there is a significant prevalence of food insecurity in the state and around 9 percent of the population are classified as extremely food insecure (consuming less than 1,800 kcal per day). The situation varies significantly within the state: 15 percent of the population in the southern region are extremely food insecure compared to 3 percent of the population living in the coastal areas. The study finds that food insecurity and vulnerability are mainly caused by a limited physical as well human asset base, slow economic growth, limited or no access to welfare provisions and public services, lack of land reform and difficulties in accessing credit institutions. Based on the findings of the analysis, the paper identifies key interventions to address the causes of food insecurity and vulnerability in Orissa. These need to address the immediate food needs of the most vulnerable and to stimulate rural development, in particular promoting agriculturally linked livelihoods. Proposed interventions include increased investment in agricultural research, improved watershed development, developing financial services and promoting small scale industries as well as micro enterprises and strengthening anti-poverty programmes within the state. Finally, the paper includes recommendations on indicators to be monitored as part of a potential Food Insecurity and Vulnerability Information and Mapping System (FIVIMS) in Orissa, focusing on a core set of indicators to be monitored at the state and district levels.

description: We calculate, as a function of temperature and density, the electron-electron interaction induced quasiparticle effective mass renormalization in 2D electron systems within the leading-order dynamically screened Coulomb interaction expansion. We find an unexpected nonanalyticity and nonmonotonicity in the temperature dependent effective mass with the renormalized mass linearly increasing with temperature at low temperatures for all densities.

description: Cotranslational folding depends on the folding speed and stability of the nascent protein. It remains difficult, however, to predict which proteins cotranslationally fold. Here, we simulate evolution of model proteins to investigate how native structure influences evolution of cotranslational folding. We developed a model that connects protein folding during and after translation to cellular fitness. Model proteins evolved improved folding speed and stability, with proteins adopting one of two strategies for folding quickly. Low contact order proteins evolve to fold cotranslationally. Such proteins adopt native conformations early on during the translation process, with each subsequently translated residue establishing additional native contacts. On the other hand, high contact order proteins tend not to be stable in their native conformations until the full chain is nearly extruded. We also simulated evolution of slowly translating codons, finding that slower translation speeds at certain positions enhances cotranslational folding. Finally, we investigated real protein structures using a previously published dataset that identified evolutionarily conserved rare codons in E. coli genes and associated such codons with cotranslational folding intermediates. We found that protein substructures preceding conserved rare codons tend to have lower contact orders, in line with our finding that lower contact order proteins are more likely to fold cotranslationally. Our work shows how evolutionary selection pressure can cause proteins with local contact topologies to evolve cotranslational folding.

description: We present a generalization of the so-called Maxwellian extended Bargmann algebra by considering a non-relativistic limit to a generalized Maxwell algebra defined in three spacetime dimensions. The non-relativistic Chern-Simons gravity theory based on this new algebra is also constructed and discussed. We point out that the extended Bargmann and its Maxwellian generalization are particular sub-cases of the generalized Maxwellian extended Bargmann gravity introduced here. The extension of our results using the semigroup expansion method is also discussed.

description: The economy of Trinidad and Tobago is booming, in particular as a consequence of increased energy production and the historical high oil prices. Whilst general inflation has remained relatively low for much of the present economic boom, substantial increases in retail food prices have been observed, in particular since 2005. This paper looks at the development of retail food prices, its causes, the potential impact thereof in terms of food security and possible policy options for addressing this. It concludes that whilst households with low income are the groups most affected by the food price increases and will continue to be so in the wake of increasing international prices, it is unlikely that the price increases in isolation will throw off Trinidad and Tobago's path towards meeting the MDG 1 hunger target and bringing the share of undernourished people down to 6.5% by 2015. However, food security problems will remain, in particular related to overweight and obesity caused by unbalanced diets. Analysing the food marketing systems according to domestic production system (export versus domestic consumption), product type (fresh versus frozen and processed) and origins (imported versus domestic), the paper identifies potential causes of price increases. These include increases in price margins, international price changes and market conditions that vary greatly for different commodities, ranging from competitive to oligopolistic. Finally, the paper identifies areas of potential interventions related to direct price interventions, social protection, agricultural investment and trade facilitation.

description: Many governments intervene directly in agricultural product, in particular food, markets. A quantitative assessment of the impact of the policy changes on the desired objectives is important as it helps inform and shape the policy debate on the reform alternatives and increases transparency of government policy. This paper reviews the literature on multimarket models which offer more accurate ex ante impact analysis than single-market models by including potentially important indirect effects. While fairly complex and requiring large amounts of data multi-market models are however much simpler than computable general equilibrium models. They are typically applied at the sector level and have proven quite popular in particular in agricultural policy reform impact analysis. While more recent work has emphasized the poverty reduction and income distribution objective the models can generate a range of information relevant to policy makers.
