Ethnicity, Identity and Cartography: Possession/Dispossession, Homecoming/Homelessness in Contemporary Assam
Creators: name: Sarma, Parag Moni
Publisher: name: Studies of Transition States and Societies
Year: 2013
Subjects: identity; ethnicity; transactive domain; resistant pluralism; cartography

description: Ethnicity is emerging as a focal consideration in the politics of identity in contemporary Assam, a state of the Indian union in the North East of India. Often identiﬁ ed as a ﬂ ash point in the subversive politics that question the logistics of the Indian nation, North East India is emerging as a cartographic domain that posits questions of internal colonialism and hegemony. Cartographic reorientation of territory based on factors of linguistic and ethnic identity is perceived as a way to acquire new homelands that will foster self-validation and the ‘all round development’ of the people. The North East of India is dotted with armed insurrection for autonomous territories under the Indian Union or total severance, depending on the population and the spatial domain of the ethnic groups in question. The linkages with questions of social, cultural and political marginalisation, as well as political assertion provide interesting scope for academic exploration. The present paper seeks to understand and trace such assertive movements in Assam to forces of historical neglect as well as the rhetoric of marginalisation that is surfeit in contemporary assertive idioms of diﬀ erent ethnic groups.

description: A new approach to the kinetic simulation of plasmas in complex geometries, based on the Particle-in- Cell (PIC) simulation method, is explored. In the two dimensional (2d) electrostatic version of our method, called the Arbitrary Curvilinear Coordinate PIC (ACC-PIC) method, all essential PIC operations are carried out in 2d on a uniform grid on the unit square logical domain, and mapped to a nonuniform boundary-fitted grid on the physical domain. As the resulting logical grid equations of motion are not separable, we have developed an extension of the semi-implicit Modified Leapfrog (ML) integration technique to preserve the symplectic nature of the logical grid particle mover. A generalized, curvilinear coordinate formulation of Poisson's equations to solve for the electrostatic fields on the uniform logical grid is also developed. By our formulation, we compute the plasma charge density on the logical grid based on the particles' positions on the logical domain. That is, the plasma particles are weighted to the uniform logical grid and the self-consistent mean electrostatic fields obtained from the solution of the logical grid Poisson equation are interpolated to the particle positions on the logical grid. This process eliminates the complexity associated with the weighting and interpolation processes on the nonuniform physical grid and allows us to run the PIC method on arbitrary boundary-fitted meshes.

Language and Identity in Ukraine: Was it Really Nation-Building?
Creators: name: Polese, Abel
Publisher: name: Studies of Transition States and Societies
Year: 2014
Subjects: Ukraine; nationalism; nation-building; language; identity

description: After the collapse of three socialist federations in Eastern Europe, the expression ‘nation-building’ returned to the heart of academic debates. Like other former socialist republics, Ukraine has started its nationbuilding project trying to balance between a limitation of centrifugal forces and the ‘nationalisation’ (Brubaker 1994) of the state. This article examines the main features of language policies within the Ukrainian nation-building project and adopts a dual approach. It ﬁ rst surveys the political will that has been incarnated in language policies since 1991, and how national identity has been aﬀ ected by those policies. However, it counterpoises this approach with an analysis of bottom actors and their attitude towards language policies. The framework constructed is intended to question the idea that nation-building is mainly an elite driven process and to suggest that common people can participate in a political project by renegotiating its features at the local level.

description: A Brownian particle moving across a porous membrane subject to an oscillating force exhibits stochastic resonance with properties which strongly depend on the geometry of the confining cavities on the two sides of the membrane. Such a manifestation of stochastic resonance requires neither energetic nor entropic barriers, and can thus be regarded as a purely geometric effect. The magnitude of this effect is sensitive to the geometry of both the cavities and the pores, thus leading to distinctive optimal synchronization conditions.
Spherical perturbations of hairy black holes in designer gravity theories

description: We study the spectrum of scalar $l=0$ quasi-normal frequencies of Anti-de-Sitter hairy black holes in four and five dimensional designer gravity theories of the Einstein-scalar type, arising as consistent truncations of $ \mathcal{N} = 8$ gauged supergravity. In the dual field theory, such hairy black holes represent thermal states in which the operator corresponding to the bulk scalar field is condensed, due to the multi-trace deformation associated with non-standard boundary conditions. We show that, in a particular class of models, the effective potential describing the vacua of the deformed dual theory can be identified, at large values of the condensate, with the deformation plus the conformal coupling of the condensate to the curvature of the boundary geometry. In this limit, we show that the least damped quasi-normal frequency of the corresponding hairy black holes can be accurately predicted by the curvature of the effective potential describing the field theory at finite entropy.

Social and Political Perceptions of the Borat Phenomenon in Kazakhstan: Evidence from a Case Study of University Students

Subjects: Kazakhstan; Borat; KIMEP; Sacha Baron Cohen; Nazarbayev

description: This article begins by chronicling and evaluating the reaction of the government of Kazakhstan to Sacha Baron Cohen’s ﬁ lm Borat—Cultural Learnings of America for Make Beneﬁ t Glorious Nation of Ka zakh stan. It then compares and contrasts the oﬃ cial government reaction with the expressed attitudes of local members of Kazakhstan’s young English-speaking elites. This study is based on the results of a survey of almost ﬁ ve hundred young university students conducted in March 2007 at the Kazakhstan Institute of Man age ment, Economics and Strategic Research (KIMEP), the most prestigious university in the country. The sample gives a snapshot of those most likely to have been aware of Borat - the young, internet-savvy, educated urban elite - and inter alia provides insights into how respondents in Kazakhstan thought the movie impacted their country and would inﬂ uence how they were treated abroad. The survey results suggest that while responses to Borat were heterogeneous, most students accepted that the choice of Kazakh stan as a target for satire was coincidental rather than conspiratorial. Despite oﬃ cial eﬀ orts to ban the movie, a majority of the respondents had seen the ﬁ lm and believed that the ban was a mistake. Also, while recognising that Borat would raise Kazakhstan’s proﬁ le in the world, respondents doubted it would increase knowledge, and some feared a change in their treatment when travelling abroad.

description: We report what is believed to be the first example of fully continuous, 24-hour vertical monitoring of atmospheric optical turbulence. This is achieved using a novel instrument, the 24-hour Shack-Hartmann Image Motion Monitor (24hSHIMM). Optical turbulence is a fundamental limitation for applications such as free-space optical communications, where it limits the achievable bandwidth, and ground-based optical astronomy, restricting the observational precision. Knowledge of the turbulence enables us to select the best sites, design optical instrumentation and optimise the operation of ground-based optical systems. The 24hSHIMM estimates the vertical optical turbulence coherence length, time, angle and Rytov variance from the measurement of a four-layer vertical turbulence profile and a wind speed profile retrieved from meteorological forecasts. To illustrate our advance we show the values of these parameters recorded during a 35-hour, continuous demonstration of the instrument. Due to its portability and ability to work in stronger turbulence, the 24hSHIMM can also operate in urban locations, providing the field with a truly continuous, versatile turbulence monitor for all but the most demanding of applications.

description: We investigate the concept of equivariant quantization over the superspace R^{p+q|2r}, with respect to the orthosymplectic algebra osp(p+1,q+1|2r). Our methods and results vary upon the superdimension p+q-2r. When the superdimension is nonzero, we manage to obtain a result which is similar to the classical theorem of Duval, Lecomte and Ovsienko: we prove the existence and uniqueness of the equivariant quantization except in some resonant situations. To do so, we have to adapt their methods to take into account the fact that the Casimir operator of the orthosymplectic algebra on supersymmetric tensors is not always diagonalizable, when the superdimension is negative and even. When the superdimension is zero, the situation is always resonant, but we can show the existence of a one-parameter family of equivariant quantizations for symbols of degree at most two.

Ten structure correspondences are involved in getting the relations. This situation is more complicated than the spin-1/2 baryon case. The obtained results may help to further investigations involving the $Δ(1232)$ baryons.

description: Zero-point quantum fluctuations of a Néel order can produce effective interactions between quasi-orphan spins weakly coupled to the lattice. On the $\sqrt{3}\times\sqrt{3}-$distorted triangular lattice, this phenomenon leads to a correlated partially disordered phase. In this article, we use matrix product state methods to study a similar model: the $S=1/2$ stuffed square lattice. Tunning the exchange amplitudes we go from a square lattice plus orphan central spins at $J'/J =0$, to the union jack lattice at $J'/J=1$, and a square lattice including all spins at $J/J'=0$. We calculate the complete antiferromagnetic phase diagram, dominated by ferrimagnetic and Néel orders, and compare with existing results. Most importantly, we find a partially disordered phase in the weakly frustrated regime. In this phase, the Néel order from the square lattice is unaffected, while the central spins form a collective state with exponentially decaying double striped correlations. We also study the role of quantum fluctuations by introducing an ordering staggered magnetic field on the square sublattice, and find that the central spins order ferromagnetically when fluctuations from the Néel order are suppressed.

In this paper we consider some of the most challenging proposals of this kind and we show why they cannot work.

Rationaliy and Utility of Evaluation Reseach in Policy Making
Creators: name: Lake, Anda
Publisher: name: Studies of Transition States and Societies
Year: 2013
Subjects: rationality; policy impact assessment; evaluation research; utilisation of evaluation research

description: In this article, the author explores the issues associated with the practical signiﬁ cance of evaluation research in the policy making environment of Latvia. Sporadic, selective and rare use of the results of evaluation research is viewed as the central issue of the paper. The objective of this article is to reveal the connection between the action strategy of the groups involved in the implementation of evaluation research and manifestations of practical signiﬁ cance of evaluation. Implementation, utilisation and practical importance of evaluation research are examined not only in relation to rational action strategies of the groups, but also in relation to the understanding of the concept of practical signiﬁ cance of evaluation research. The theoretical framework of the article is based on the conceptual understanding of J. Habermas’ purposive rationality and communicative rationality, as well as C. H. Weiss’ understanding of practical utilisation of evaluation (the instrumental and enlightened models). The practical importance of evaluation research as well as action strategies of implementing evaluation research are studied empirically in the form of qualitative interviews. The author concludes that the rational action strategy (typical of the Latvian policy making environment) of the groups involved in evaluation is not readily compatible with the evaluation approach that focuses on practical utilisation. The lack of communicative rationality in the action strategy of the interacting and involved groups substantially diminishes the role of evaluation research in the identiﬁ cation and implementation of the most eﬀ ective models of solving social issues in policy making in Latvia.

Comparative Party System Analysis in Central and Eastern Europe: the Case of the Baltic States
Creators: name: Saarts, Tõnis
Publisher: name: Studies of Transition States and Societies
Year: 2013
Subjects: political parties; party systems; Baltic States; Central and Eastern Europe; comparative analysis

description: The nature of the party systems in Central and Eastern Europe (CEE) has puzzled many scholars. High instability of the party systems and their speciﬁ c evolution makes the application of theoretical models designed predominately for Western European party politics problematic. The paper puts forward the argument that we should further elaborate and specify the models for a small N comparative party system analysis in CEE countries and to incorporate some region speciﬁ c components into the framework. The essential dimensions included into proposed comparative framework are as follows: (1) the stability of the party system, (2) party system fragmentation, (3) parties’ penetration into society, (4) the ideology and origins of the major parties, (5) the dominant cleavage constellations framing the party competition (6) the strength of the party organizations. The above-mentioned dimensions are expected to capture the most important aspects that make the diﬀ erence between the party systems in general, and each dimension is complemented with the speciﬁ c additional variables suitable for party system analysis in CEE in particular. The framework will be tested on the Baltic States, which party systems are often regarded to be very similar to each other. However, the analysis will demonstrate that based on the above-mentioned framework, very signiﬁ cant and noteworthy diﬀ erences will be revealed.

description: Low-frequency 1/f noise in electronics is a conductance fluctuation, that has been expressed in terms of a mobility "$α$-noise" by Hooge and Kleinpenning. Understanding this noise in graphene is a key towards high-performance electronics. Early investigations in diffusive graphene have pointed out a deviation from the standard Hooge formula, with a modified expression where the free-carrier density is substituted by a constant density $n_Δ\sim10^{12}\;\mathrm{cm^{-2}}$. We investigate hBN-encapsulated graphene transistors where high mobility gives rise to the non-linear velocity-saturation regime. In this regime, the $α$-noise is accounted for by substituting conductance by differential conductance $G$, ressulting in a bell-shape dependence of flicker noise with bias voltage $V$. The same analysis holds at larger bias in the Zener regime, with two main differences: the first one is a strong enhancement of the Hooge parameter reflecting the hundred-times larger coupling of interband excitations to the hyperbolic phonon-polariton (HPhP) modes of the mid-infrared Reststrahlen (RS) bands of hBN. The second is an exponential suppression of this coupling at large fields, which we attribute to decoherence effects. We also show that the HPhP bands control the amplitude of flicker noise according to the graphene-hBN thermal coupling estimated with microwave noise thermometry. The phenomenology of $α$-noise in graphene supports a quantum-coherent bremsstrahlung interpretation of flicker noise.

Hierarchy in Moldova-Russia Relations: The Transnistrian Eﬀect
Creators: name: Crandall, Matthew
Publisher: name: Studies of Transition States and Societies
Year: 2013
Subjects: Moldova; Transnistria; Russia; Westphalian sovereignty; hierarchical sovereignty

description: This article examines the eﬀ ect of the Transnistrian area on Moldova-Russia relations. David Lake’s concept of hierarchy will be used as the theoretical framework. The article examines why Russia’s mechanisms of inﬂ uence should be seen as a reﬂ ection of a hierarchical relationship between Russia and Moldova. The article begins by explaining why this work has chosen a hierarchical framework and a brief introduction of Transnistria. This is followed by two sections of analysis: security and economy. These two sections will also contain subsections on events that highlight the hierarchical nature of the Moldova-Russia relationship. This article shows that Russia clearly has a hierarchical relationship with Moldova. David Lake’s theory proves to be a useful tool in understanding Moldovan-Russian relations.

Remembering Independence, Desiring Enemies: Reflections on Nationhood in Contemporary Lithuania
Creators: name: Kalpokas, Ignas
Publisher: name: Studies of Transition States and Societies
Year: 2013
Subjects: Lithuania; independence; memory; grand narratives; textbooks

description: The paper addresses the remembrance of events surrounding the restoration of Lithuanian independence, as well as their repercussions on the present, concentrating on the younger generation that does not have ﬁ rst-hand experience of the period and, therefore, has to rely on other people’s accounts, textbooks, and other sources.If one considers the state and, especially, its social (or communal) dimension as impossible totalities, memory and history acquire signiﬁ cant importance as they both provide ‘a magma of signiﬁ cations’, out of which particular signifying structures are instituted in order to anchor meaning and exhort a unifying claim through dominant narratives that tend to subjugate the otherwise inevitable variety of discourses. The discourse of the Lithuanian history textbooks is analysed by outlining its emphasis on unity and selfsacriﬁ ce in 1988-1991, and by portraying the Lithuanian history as an unending struggle against enemies and their malevolent plots. Also, considering the accounts of young people, two tendencies are visible: ﬁ rst, a bias towards images of unity and self-sacriﬁ ce depicting the period concerned, second, the predilection to employ the categories of ‘aliens’ and ‘enemies’ is evident, signiﬁ cantly aﬀ ecting perceptions of the present with widespread images of disintegration and decay in the absence of the Other.

description: Tuberculosis (TB) is still considered a leading cause of death and a substantial threat to global child health. Both TB infection and disease are curable using antibiotics. However, most children who die of TB are never diagnosed or treated. In clinical practice, experienced physicians assess TB by examining chest X-rays (CXR). Pediatric CXR has specific challenges compared to adult CXR, which makes TB diagnosis in children more difficult. Computer-aided diagnosis systems supported by Artificial Intelligence have shown performance comparable to experienced radiologist TB readings, which could ease mass TB screening and reduce clinical burden. We propose a multi-view deep learning-based solution which, by following a proposed template, aims to automatically regionalize and extract lung and mediastinal regions of interest from pediatric CXR images where key TB findings may be present. Experimental results have shown accurate region extraction, which can be used for further analysis to confirm TB finding presence and severity assessment.

description: We study experimentally and theoretically a beam splitter setup for guided atomic matter waves. The matter wave is a guided atom laser that can be tuned from quasi-monomode to a regime where many transverse modes are populated, and propagates in a horizontal dipole beam until it crosses another horizontal beam at 45$^{\rm o}$. We show that depending on the parameters of this $X$ configuration, the atoms can all end up in one of the two beams (the system behaves as a perfect guide switch), or be split between the four available channels (the system behaves as a beam splitter). The splitting regime results from a chaotic scattering dynamics. The existence of these different regimes turns out to be robust against small variations of the parameters of the system. From numerical studies, we also propose a scheme that provides a robust and controlled beam splitter in two channels only.
Post-Socialist Fathers ‘At Home’ and ‘Away from Home’ in ‘Old Europe’: Facing the Challenge through Masculine Identity Talk

Subjects: masculinities; migration; discourse; identity talk; intersectionality; Estonia

description: This article focuses on those Estonian male migrants to ‘Old Europe’1 who spend most of their time in the domestic realm as caring fathers and supportive spouses to their wives, who are meanwhile advancing their transnational careers. In this context, masculine identity talk can be understood in terms of strategies employed in response to the challenge to the men’s masculinity that this atypical life choice is likely to entail. Identity is viewed in this article as a processual phenomenon that is relentlessly, although not always deliberately, (re)formulated in discourse, rather than determined by the assigned social roles. Analysis of in-depth interviews reveals that there are varied discourses in use that eﬃ ciently reconstruct the interviewees’ sense of personal signiﬁ cance. Interestingly, men predominantly combine ‘alternative’ discourses (‘caring father’, ‘supportive spouse’, ‘civilised adult’), which potentially undermine Estonian idealised masculinity, with the ‘conservative’ discourses (‘professional man’, ‘well-oﬀ ’), that reinforce the Estonian male norm. Men draw on a range of potentially oppositional and conﬂ icting resources for constructing masculinity, without much reﬂ exive selection from their part. Hence, the discourses men engage in position the men as much as the men appear to consciously position themselves in the discourses. This poststructuralist account of identity is located within a more structural historical context of transition and change in contemporary Europe.

description: This article aims to map formal adult education in terms of the determinants of educational upgrading later in life, relating these back to social inequalities from a comparative perspective, and to labour market outcomes following participation, particularly the probability of being employed. It relies on a longitudinal analysis of data from the United Kingdom, Spain, Sweden and Russia. Results show that educational upgrading at mature ages has the potential for reducing social inequalities in all the countries analysed. Upgraders tend to come from a medium to low education background in Russia and the UK but from the tertiary educated in Spain and Sweden. Labour market marginalisation increases the chance of upgrading particularly in Sweden. Upgrading tends to increase employment opportunities, though these are in some cases conditional on being employed whilst studying. This is speciﬁ cally the case for Russia and for men in the UK. We also found important country-speciﬁ c gender diﬀ erences in the eﬀ ect of upgrading on employment opportunities, according to which women beneﬁ t more than men in the UK and Sweden. We conclude with some suggestions about the institutional eﬀ ects that produce diﬀ erences between countries.

description: Before exploring the selectivity of educational attainment in detail, this article extensively describes the contours of educational systems in Central and Eastern European (CEE) countries. These countries provide an interesting setting in view of their post-secondary education expansion and differentiation, as well as their variation in the degree of vocational orientation at the secondary level. Drawing on high quality, national micro data, we find that students from disadvantaged family backgrounds who manage to enter post-secondary education are ‘diverted’ to second-tier post-secondary institutions, while longterm university programs are more likely to be dominated by students whose parents have an academic background. At the secondary level, we confirm the patterns of negative selection among students from lower social backgrounds into lower vocational programs. This diversion effect at the secondary level is especially pronounced in CEE countries that inherited a strong secondary vocational system and reinstalled early tracking.

description: Cross-domain Sequential Recommendation (CSR) is an emerging yet challenging task that depicts the evolution of behavior patterns for overlapped users by modeling their interactions from multiple domains. Existing studies on CSR mainly focus on using composite or in-depth structures that achieve significant improvement in accuracy but bring a huge burden to the model training. Moreover, to learn the user-specific sequence representations, existing works usually adopt the global relevance weighting strategy (e.g., self-attention mechanism), which has quadratic computational complexity. In this work, we introduce a lightweight external attention-enhanced GCN-based framework to solve the above challenges, namely LEA-GCN. Specifically, by only keeping the neighborhood aggregation component and using the Single-Layer Aggregating Protocol (SLAP), our lightweight GCN encoder performs more efficiently to capture the collaborative filtering signals of the items from both domains. To further alleviate the framework structure and aggregate the user-specific sequential pattern, we devise a novel dual-channel External Attention (EA) component, which calculates the correlation among all items via a lightweight linear structure. Extensive experiments are conducted on two real-world datasets, demonstrating that LEA-GCN requires a smaller volume and less training time without affecting the accuracy compared with several state-of-the-art methods.

The Effect of Gender and Ethnicity and their Intersection on Work Satisfaction and Earnings in Estonia, 1993-2008

Subjects: labour market inequalities; gender; ethnicity; Estonia; intersectionality

description: This article examines trends in the labour market position, deﬁ ned in terms of three dimensions – earnings, perceived job security and overall job satisfaction – among four population groups in Estonia – Estonian men and women and Russian-speaking men and women. We explore how the labour market position of these groups changed between 1993 and 2008.We used data from 1993 and 2008, collected in the population survey Work, Family and Leisure, designed by the Institute of International and Social Studies at Tallinn University. We carried out a two-step analysis: ﬁ rst, we conducted descriptive analysis to explore changes in the labour market situation of men and women of two ethnic groups in the period of 1993-2008; and second, we used models of multivariate analysis of variances to examine how gender, ethnicity and occupational status as well as the intersection of these variables are related to earnings, job security and job satisfaction.We found that Estonian men have emerged as the most successful group in the labour market, while the labour market position of Russian-speaking women is the most disadvantaged compared to other groups in terms of earnings, job security and job satisfaction. We suggest that these labour market inequalities could be increasing, and that the interaction of gender and ethnicity might become increasingly important in shaping labour market outcomes.

Managing Drinking Time, Space and Networks as Strategies for Avoiding Alcohol-Related Harm Among Young Estonian Adults
Creators: name: Kobin, Maarja
Publisher: name: Studies of Transition States and Societies
Year: 2013
Subjects: young people; harm; framework; drinking context; Estonia

description: Research on drinking in Estonia, mainly surveys, indicates that alcohol consumption has increased steadily over the last ﬁ fteen years. However, these quantitative studies provide little information about drinking habits and the meanings that are attributed to diﬀ erent consumption patterns. In addition, there is no research that explores how alcohol-related harm is controlled or managed, especially among young people. Current research on alcohol-related harm, primarily from the UK, emphasises calculated hedonism and shows clearly that drinking ‘depends on the context’. Relying on Goﬀ man’s concept of ‘frame work’, the aim of the current paper is to analyse or give structure to the ‘context’ by distinguishing the frameworks of drinking time, space and networks that guide young Estonians in their interpretations and perceptions of alcohol related harm, and that also act as a basis for legitimising drinking practices. Diﬀ erentiating the frames helps to show the dynamics of drinking practices and the interactions in ‘context’.The research is based on open-ended and focus group interviews with young people from rural and urban areas in Estonia and is supported by participant observation in diﬀ erent situations where alcohol is consumed in order to provide a broader view and interpretation on young people’s drinking.

description: This article analyses the risk of receiving online sexual messages and experiencing harm among Estonian children. In particular, the paper examines the association between receiving sexual messages and behavioural, psychological and demographic characteristics, and the social mediation of children’s Internet use. Estonian data from ‘EU Kids Online’ survey are used, involving 780 children aged 11-16. Results demonstrate that 19% of children who use the Internet have received online sexual messages, and 6% have felt disturbed. The probability of receiving sexual messages online is higher for children with risky online and oﬄ ine behaviour and psychological diﬃ culties. Perceiving online messages as sexually harassing is higher among children with excessive Internet use, lower levels of parental monitoring and higher levels of peer mediation of Internet use. The risk of exposure to harassing sexual messages also diﬀ ers by age and, more notably, by the minority status. Mediation by parents and teachers plays an insigniﬁ cant role in reducing teenagers’ risks of receiving sexual messages.

Estonia – Highly Unequal but Classless?

Subjects: class; class analysis; public class discourse; post-communist transformation; Estonia

description: In this short essay, we try to assess the utility of class analyses for understanding the contemporary Estonian society. Erik Wright (2009) identiﬁ es three strands of class analysis: a stratiﬁ cation approach, a Weberian approach and a Marxist approach. We address the following questions: Which kind of class analysis is most present in Estonia today? Which is most needed? The main conclusion is that due to this marginalisation of class discourse, as well as the power of national/ethnic discourse and transitional culture, those most economically vulnerable were deprived of the cultural and discursive resources to resist the most the extreme market-oriented policies. The conditions for structuration of class relations were created, while the class and inequality discourse was marginalised.

description: Modeling the dynamics of the formation and evolution of protostellar disks as well as the history of stellar mass accretion typically involve the numerical solution of complex systems of coupled differential equations. The resulting mass accretion history of protostars is known to be highly episodic due to recurrent instabilities and also exhibits short timescale flickering. By leveraging the strong predictive abilities of neural networks, we extract some of the critical temporal dynamics experienced during the mass accretion including periods of instability. Particularly, we utilize a novel form of the Echo-State Neural Network (ESN), which has been shown to efficiently deal with data having inherent nonlinearity. We introduce the use of Optimized-ESN (Opt-ESN) to make model-independent time series forecasting of mass accretion rate in the evolution of protostellar disks. We apply the network to multiple hydrodynamic simulations with different initial conditions and exhibiting a variety of temporal dynamics to demonstrate the predictability of the Opt-ESN model. The model is trained on simulation data of $\sim 1-2$ Myr, and achieves predictions with a low normalized mean square error ($\sim 10^{-5}$ to $10^{-3}$) for forecasts ranging between 100 and 3800 yr. This result shows the promise of the application of machine learning based models to time-domain astronomy.
