Physics-based approach to wave statistics and probability
Creators: name: Babanin, Alexander
Publisher: name: Swinburne
Year: 2024

description: Design criteria in ocean engineering, whether this is one in 50 years or one in 5000 years event, are hardly ever based on measurements, and rather on statistical distributions of relevant metocean properties. Of utmost interest is the tail of these distributions, that is rare events such as the highest waves with low probability. Engineers have long since realised that the superposition of linear waves with narrow-banded spectrum as depicted by the Rayleigh distribution underestimates the probability of extreme wave crests, and is not adequate for wave heights either, which is a critical shortcoming as far as the engineering design is concerned. Ongoing theoretical and experimental efforts have been under way for decades to address this issue. Here, we will concentrate on short-term statistics, i.e. probability of crests/heights of individual waves. Typical approach is to treat all possible waves in the ocean or at a particular location as a single ensemble for which some comprehensive solution can be found. The oceanographic knowledge, however, now indicates that no single and united comprehensive solution is possible. Probability distributions in different physical circumstances should be different, and by combining them together the inevitable scatter is introduced. The scatter and the accuracy will not improve by increasing the bulk data quality and quantity, and it hides the actual distribution of extreme events. The groups have to be separated and their probability distributions treated individually. The paper offers a review of physical conditions, from simple one-dimensional trains of free waves to realistic twodimensional wind-forced wave fields, in order to understand where different probability distributions can be expected. If the wave trains/fields in the wave records are stable, distributions for the second-order waves should serve well. If modulational instability is active, rare extreme events not predicted by the second-order theory should become possible. This depends on wave steepness, bandwidth and directionality. Mean steepness also defines the wave breaking and therefore the upper limit for wave heights in this group of conditions. Under hurricane-like circumstances, the instability gives way to direct wind forcing, and yet another statistics is to be expected.

description: Plant molecular farming refers to the process of utilising plants as bioreactors to produce high value proteins, including enzymes, antibodies, and other therapeutic molecules. Almost all molecular farming initiatives employ Nicotiana benthamiana as a host plant. Herein, we investigated the potential of a model legume, Medicago truncatula, as an alternative platform for synthesis of heterologous protein. We exploited well established methodologies developed for the study of root endosymbioses to genetically transform M. truncatula root systems via Agrobacterium rhizogenes. The suitability of M. truncatula as a platform for the production of heterologous proteins was then examined through the cultivation of composite plants and immortalised root organ cultures (ROCs) that accumulate recombinant Green fluorescent protein (GFP). Our results demonstrate that recombinant GFP accumulates at high levels in composite M. truncatula plants up to 15 weeks post-transformation. Immortalised ROC lines continue to accumulate recombinant GFP beyond 57 weeks post-transformation. Purification of recombinant GFP from ROCs resulted in yields of 780 mg/kg and 194 mg/kg of root tissue, respectively. Sustained accumulation of high levels of recombinant GFP accordingly demonstrate the potential of M. truncatula as a viable alternative platform for heterologous protein production.

description: With higher education increasingly available to young people regardless of their socioeconomic status, the question “what to study” is steadily replacing “whether to study” as the key question facing students today. This paper examines, in a comparative and methodologically innovative manner, incentives for studying various fields measured by net present value of university education. We use data from five European countries (France, Italy, Hungary, Poland and Slovenia) and include (opportunity) costs in the computation. Results suggest that enrolling in STEM (science, technology, engineering and mathematics) faculties is often not the best bargain, especially for female students. Decisions made by students are therefore consistent with their private returns, which points to the fact that if policy-makers desire to induce changes in behaviour, they should consider changing the incentives themselves.

description: This research explores the role of environmental activism on social media that directly targets the fast fashion industry and consumerism by raising awareness and promoting sustainability. Previous research highlights the significance of environmental activism through social media that focuses on raising awareness regarding fashion (Nucci & Hibberd, 2021; Scully, 2021). This research aims to fill empirical gaps to better understand the strategies of environmental activism that circulate on social media to demote fast fashion consumerism and promote the sustainable changes in light of this recent platform for and subject of activism. By adopting a digital ethnography, it analyzes over 120 TikTok videos from 2020 to 2023 that discuss fast fashion and the environment by examining actors’ discussions of fast fashion’s effect. The analysis specifically focuses on content and methods of content delivery. Findings reveal the educational orientation to motiving the audience, including calls for boycotts The discussion considers how digital activism may support future environmental activism efforts. Cette étude explore le rôle de l'activisme environnemental sur les médias sociaux qui cible directement l'industrie de la mode rapide et le consumérisme en sensibilisant et en promouvant la durabilité. Des recherches antérieures ont mis en évidence l'importance de l'activisme environnemental sur les médias sociaux, qui se concentre sur la sensibilisation à la mode (Nucci & Hibberd, 2021 ; Scully, 2021). Cette recherche vise à combler les lacunes empiriques afin de mieux comprendre les stratégies d'activisme environnemental qui circulent sur les médias sociaux pour démolir le consumérisme de la fast fashion et promouvoir les changements durables à la lumière de cette récente plateforme et de ce sujet d'activisme. En adoptant une ethnographie numérique, il analyse plus de 120 vidéos TikTok de 2020 à 2023 qui discutent de la fast fashion et de l'environnement en examinant les discussions des acteurs sur l'effet de la fast fashion. L'analyse se concentre spécifiquement sur le contenu et les méthodes de diffusion du contenu. Les résultats révèlent l'orientation éducative de la motivation du public, y compris les appels au boycott. La discussion porte sur la façon dont l'activisme numérique peut soutenir les futurs efforts d'activisme environnemental.

description: NEUJOBS Working Paper No. 4.5.3 Abstract:
The effect of specific education policies, such as ability grouping, preschool attendance on educational outcomes and equity has been the subject of much scholarly and political debate. Our paper adds to this debate by examining the association between such policies and equity for children of different abilities. In this way we arrive at a nuanced picture of how such specific education policies might affect different children. We study the issue at a country level for 29 OECD countries with identical methodology, enabling us to show cross-country differences. Linear regression results show that countries differ in terms of how the policy measures are correlated with equity and educational outcomes. Concentrating on equity, quantile regression results indicate that in most countries the association between education policy variables and equity is evenly distributed across the ability distribution. In some countries, however, (Austria, Spain, the US, Belgium, Latvia and Hungary) the policy variables have an especially stratifying or an especially equalising effect for the less able and in other countries for the more able. This means that ability grouping and/or participation in pre-primary education can reinforce or cushion the negative effect of a low socio-economic background more either for the more, the less able or at the median. This means that policy makers – especially in these countries mentioned – should take into account that ability grouping or participation in pre-primary education might have a different effect at different ends of the performance distribution.
Instability of wave trains and wave probabilities

Typical approach is the treating all possible waves in the ocean or at a particular location as a single ensemble for which some comprehensive solution can be obtained. The oceanographic knowledge, however, now indicates that no single and united comprehensive solution is available. We would expect the probability distributions of wave height to depend on a) whether the waves are at the spectral peak or at the tail; b) on wave spectrum and mean steepness in the wave field; c) on the directional distribution of the peak waves; d) on whether the waves are in deep water, in intermediate depth or in shallow water; e) on wave breaking; f) on the wind, particularly if it is very strong, and on the currents if they have suitable horizontal gradients. Probability distributions in the different circumstances according to these groups of conditions should be different, and by combining them together the inevitable scatter is introduced. The scatter and the accuracy will not improve by increasing the bulk data quality and quantity, and it hides the actual distribution of extremes. The groups have to be separated and their probability distributions treated individually. We suggest to proceed systematically through the available data sets, by using physical understanding rather than the bulk statistical approach. If the wave trains/fields in the wave records are stable, distributions for the second-order waves should serve well. If modulational instability is active, rare extreme events not predicted by the second-order theory should become possible. This depends on wave steepness, bandwidth and directionality. Mean steepness also defines the wave breaking and therefore the upper limit for wave heights in this group of conditions.

description: NEUJOBS Working Paper No. 6.2 Abstract:
This report studies the link between labour regimes and technological innovation in Central and Eastern Europe, analysing in some detail two key sectors that have gained in importance in the economies of the region: the automotive and software industries. Defining success as a move up-market in terms of production and/or gaining a dominant and stable share in the world markets, both sectors have been successful regionally and, in certain aspects, also globally. Yet, the character and levels of innovation and R&D within them differ. Whereas innovation in automotive sectors – to the extent that it takes place – is imported, much innovation in the software industry is indigenous. We define a labour regime broadly to include labour availability, quality and provision of skills, labour market flexibility, or industrial relations. We focus on evaluating the role of several institutional and policy areas, especially education and skill provision systems, migration policy, labour market regulation and employment relations. The elements of labour regimes that have the greatest influence on development also vary between sectors. Two sectoral case studies are linked by a focus on three interrelated areas on a) the relevance of the provision and availability of skills and the importance of local labour supply; b) openness to foreign labour as a source of knowledge in some cases and in others of numerical flexibility; and c) the existence and importance of clustering as a source of knowledge-sharing and knowledge-generation. Employment and labour-market flexibility and its links to legal and institutional frameworks are cross-cutting issues that come back in the three overarching themes. Flexibility takes different forms in the two sectors. While it might not be directly related to the innovation process as such, it has contributed to the increased competitiveness of the two sectors and supported a shift up-market in sophistication. Our general finding is that for both types of innovation – ‘imported’, which prevailed in automotive sector and ‘indigenous’ that was shown to exist fairly widely in the software industry – the availability of human capital, its structure and skill-sets have been important in order for the higher-end activities to be localised or nurtured in Central and Eastern Europe. However, the differences in the generation and implementation of innovation and in the nature of the production processes are reflected in significant differences in labour regimes.

description: The NISPAcee Journal of Public Administration and Policy, Vol. V, No. 2, Winter 2012/2013 Abstract:
Discussion of politico-administrative relations as well as the research on agencies generally treats the “politicisation” of agency management as a single, “black-box” concept, according to which agency managements (and other senior civil servants) are either political or not. Our paper shows that, using a strict, but widely applied definition of what constitutes a political appointment, agency heads in Slovakia are overwhelmingly “political”, but that the implications of politicisation vary, depending on the type of politicisation. In particular, we distinguish personal nominations of the responsible minister and contrast them with party nominations based on coalition agreements. Based on a series of interviews with senior policy-makers on both sides of the politico-administrative divide, we show that the selection mechanism, incentive structure and robustness of actual accountability mechanisms differs more between these two types of politicisations than between the ministerial and formally “non-political” appointment.

description: Le potentiel de la rencontre entre une institution néolibérale et des notions féministes transformatrices dans le cadre de programme d’empowerment suscite nombre de débats dans la littérature féministe en relations internationales. Cette thèse propose de répondre à la question: comment les processus de néolibéralisation des féminismes s’articulent dans le discours de la Umbrella Facility for Gender Equality (UFGE) sur l’empowerment entre 2012 et 2022 ? Une analyse de discours critique est menée sur dix documents d’un organe de la Banque mondiale portant sur l’empowerment pour observer cinq processus: dépolitisation, hétéronormativisation, universalisation, homogénéisation et essentialisation. Les résultats démontrent que les processus de néolibéralisation se sont subtilisés dans le discours et mobilisent désormais des notions différentes pour parler d’empowerment tout en conservant les mêmes conceptualisations fondamentales au discours de la Banque mondiale. L’intégration variable des féminismes dans le discours de la UFGE, démontrée par l’évolution différente des processus de néolibéralisation, reflète les relations de pouvoir modulant qui peut parler et qui sera écouté.

description: NEUJOBS Working Paper No. 4.3.3 Abstract:
This paper analyses job advertisements posted on the public EU portal EURES to identify the specific skills and characteristics that are demanded in the European labour market in selected low- and medium-skilled occupations and in different sectors. This research is innovative in exploring online job advertisement data from the EURES website and quantifying different skills, personal attributes and characteristics requested by employers in three countries: the Czech Republic, Denmark and Ireland. While we find that the service sector demands non-cognitive skills more than other types of occupations, the skill-demanded mix is very diverse across the countries analysed, implying that there is no universal demand and that domestic institutions and structures affect how demand is formulated. We point to potential limits of ‘European occupational labour markets’ as we find that employers’ preferences across the three countries seem rather distinct for similar types of jobs. Our work shows that online portals can become a useful source for gathering information about the content and specificities of demand at the micro-level.

Variability of sea drag in response to meteorological and wave properties

name: Babanin, Alexander
name: Chalikov, Dmitry
Publisher: name: Swinburne
Year: 2024

description: Drag coefficient is one of the most important properties used in modelling the air-sea interactions. Most of the dependences employ the sea drag as a function of mean wind speed. The scatter of experimental data around such parametric dependences, however, is very significant and has not improved noticeably over some 30 years. This scatter imposes a serious limitation on predictions that make use of sea surface-drag parameterisations. Babanin and Makin (2008) suggested that, apart from the wind speed, the drag depends on a number of other physical properties and phenomena, whose effect on the sea drag should be investigated and incorporated in the final parameterisation in order to reduce the scatter. These properties include, among possible others, the directional spreading of the surface waves, gustiness of the wind, humidity of the air. The aim of the present study is to investigate the drag coefficient as a function of these environmental properties by means of numerical modelling with WBLM (Wave Boundary Layer Model, Chalikov and Rainchik, 2010). 1-D equations derived by Chalikov and Rainchik are used here for extensive calculations of WBL structure in order to study the respective dependences and variability of the drag coefficient.

description: The Harts Range is about two hundred kilometres north-east of Alice Springs. The area was known to be rich in minerals from the time of the first explorers. From the 1880s until the close of the industry in 1960, almost all Australian mica came from this area in the Northern Territory. Most miners were Italian who were without a mining background and who began arriving on the Field in the years following the First World War. During this period they were sponsored by their countrymen already in Central Australia. After 1945 increased numbers came to the Centre escaping post-war Italy and encouraged by Australia's immigration policies. Many of the post-war migrants brought families with them to the Field. The thesis contends that many wives worked alongside their husbands and fathers; and that as with other early settlement areas throughout Australia, women played a pivotal role. It further contends that without the use of oral evidence the social history of these Italians could not have been successfully documented. This thesis establishes that the relationship between the miners and local Aboriginal groups was atypical in the history of Central Australia. The miners utilised local Aboriginal knowledge and labour. Descendants of these Aborigines still live in the area, many at the Atitjere Community. The mining literature indicates that mining activity and settlement was concentrated in the Central Harts Range District (the study area). Remaining evidence of activity is distinctive for the aggregation of the responses of the miners to the extreme isolation and to economic deprivation. The thesis concludes that mica mining in the Harts Range sustained an interest in Central Australia from the early years of this century until 1960. Developments in transport services, such as the Plenty Highway, and the attraction of Italians to the area (who formed the basis of Central Australia's present-day Italian community) are a direct result of this activity.

description: NEUJOBS Working Paper No. 4.4.2 B Abstract:
In this paper we study theoretically how the expansion of higher education could be associated with several factors indicating a decline in the quality of degrees. We assume that the expansion of tertiary education happens through three channels and show how they are likely to reduce average study time, average wages and increase grades. Firstly, universities have an incentive through public and private funding schemes to increase their student body beyond a level where they can keep their requirements on a high level. Secondly, due to skill-biased technological change, employers have the incentive to employ mostly labour with a higher education degree. Thirdly, students have the incentive to acquire a college degree due to the employment rules, the university application rules and through the rising social reputation of education. We develop a parsimonious dynamic model in which a student, a college and an employer repeatedly make decisions about requirement levels, performance and wage levels. Our model shows that if (1) universities have the incentive to decrease entry requirements, (2) employers are more likely to employ labour with a higher education degree and (3) all types of students enroll in colleges, the grade will not necessarily act as a mechanism to make weaker students study to catch up with the more able students. In order to reestablish a quality guaranteeing mechanism, entry requirements should be set to a higher level.
Modelling of upper ocean mixing by wave-induced turbulence

Publisher: name: Swinburne
Year: 2024

description: Mixing of the upper ocean affects the sea surface temperature by bringing deeper, colder water to the surface. Because even small changes in the surface temperature can have a large impact on weather and climate, accurately determining the rate of mixing is of central importance for forecasting. Although there are several mixing mechanisms, one that has until recently been overlooked is the effect of turbulence generated by non-breaking, wind-generated surface waves. Lately there has been a lot of interest in introducing this mechanism into models, and real gains have been made in terms of increased fidelity to observational data. However our knowledge of the mechanism is still incomplete. We indicate areas where we believe the existing models need refinement and propose an alternative model. We use two of the models to demonstrate the effect on the mixed layer of wave-induced turbulence by applying them to a one-dimensional mixing model and a stable temperature profile. Our modelling experiment suggests a strong effect on sea surface temperature due to non-breaking wave-induced turbulent mixing.

description: The hydrophobic force describes the attraction between water-hating molecules (and surfaces) that draws them together, causing aggregation, phase separation, protein folding and many other inherent physical phenomena. Attempts have been made to isolate the range and magnitude of this interaction between extended surfaces for more than four decades, with wildly varying results. In this perspective, we critically analyse the application of common force-measuring techniques to the hydrophobic force conundrum. In doing so, we highlight possible interferences to these measurements and provide physical rationalisation where possible. By analysing the most recent measurements, new approaches to establishing the form of this force become apparent, and we suggest potential future directions to further refine our understanding of this vital, physical force.
Improved 3-D model for periodic waves based on initial equation

Year: 2024

description: The improved method of modelling of three-dimensional surface waves is described. Contrary to approximate HOS approach, where the vertical velocity on the surface is calculated with Taylor expansion, the given method allows to calculate the exact surface vertical velocity with estimated accuracy. The advantages of new method are discussed by comparison with HOS method. Method is based on dynamic and kinematic surface boundary conditions and elliptic equation for velocity potential written in surface-fitted coordinate system. A direct iterational solution of equation for potential usually needs a high vertical resolution what significantly slows down the speed of calculations. The separation of velocity potential into linear and nonlinear modes allows to reduce the problem to the same equations but written for nonlinear correction for linear solution. Since the correction is typically smaller by 2 decimal order than a linear constituent, the solution needs less accuracy and smaller number of vertical levels. Such improvement makes the 3-D model well suitable for performing the multi-mode and long-term calculations. Such calculations allows to investigate the nonlinear properties of 3-D wave field, mechanics and statistics of extreme waves, formation of angular spreading of waves. Being supplied by well developed algorithms of wind input and breaking dissipation model allows the simulation of long-term development of waves initially assigned as a monochromatic train of initially small waves. The details of numerical scheme as well as the results of model validation and the examples of long-term simulations of 3-D wave field are given.
Short-crestedness of fully nonlinear potential waves

description: In the oceanographic literature, short-crestedness of waves is often assumed to be the same feature as directionality, as opposed to long-crested waves which are unidirectional. Indeed, superposition of linear long-crested waves will create an interference pattern of modulated long crests. Lateral modulation of the long crests, however, is also a nonlinear phenomenon which for nonlinear waves occurs naturally even if the waves are unidirectional. These two contributions have different physics and metrics involved and have to be separated. Here, we investigate short-crestedness of three-dimensional fully-nonlinear potential deep water waves whose initial spectrum is assumed to be of Pierson-Moskowitz type with directional distribution given by cosine to the power from 2 to 64. The analysis is based on the results of long-term wave simulations performed using a numerical scheme based on solving a full three-dimensional potential equation in a rectangular domain. To characterise the wave surface properties we introduce the concept of three-dimensional steepness as the vector whose magnitude is equal to the average steepness calculated along the vector direction in a horizontal plane. The results are compared with the analysis of a linear superposition of sinusoidal waves with identical directional spectra.

Výskum je založený na dátach 32 obstarávateľov a 752 obstarávaní vo verejnom sektore v časovom rozmedzí rokov 2008-2010. Naše zistenia ukazujú, že elektronické aukcie prinášajú priemernú úsporu 10-12%, i keď ich implementácia nie je beznákladová. Ďalší výskum v tejto oblasti by sa mal venovať určeniu nákladov na zavádzanie elektronických aukcií. Výskum taktiež ukázal, že premenné ovplyvňujúce mieru úspor môžu byť ovplyvnené obstarávateľom: počtom uchádzačov a formou aukcie (otvorená vs. uzavretá). English Abstract: The paper examines use of electronic auctions (e-auctions) as an allocation mechanism in public procurement in Slovak public sector. It is based on data from 32 procurement bodies and 725 procurements in the public sector in the period 2008-2010. Our findings are that e-auctions bring average savings of 10-12% though their implementation is not free. We recommend that future research quantify costs associated with introduction of e-auctions. The paper also demonstrates that the key variables influencing level of savings can be influenced by the procuring body: number of participants and form of auction (open vs. closed).

Material: 1 specimen, both valves (no. 24082 BBU-MPS).
Description: Small size shell, with right valve (RV) long conical, 40 mm long and 20 mm in diameter at the commissural plane (Fig. 7 f-g). The ornamentation consists of dense growth lamellae (Fig. 7f). The radial bands are folds curved towards the commissure separated by a narrow interband with one fold (Fig. 7g). Left valve (LV) is highly convex, with central apex but much eroded (Fig. 7f).
 Discussion and remarks: Because we found only one specimen, the shell of Radiolites squamosus was not been cut for study in cross-section. This species is also mentioned by Lupu (1976) from RoȘia Basin (Northen Apuseni Mountains).
Age and distribution: early - middle Santonian in France (Toucas, 1907); late Santonian- early Campanian in Croatia (Polšak and Mamuzic, 1969), Romania (Lupu, 1976), Slovenia (Pleničar and Jurkovsek, 1999), middle-late Campanian in Spain (Floquet, 1991) and early Maastricthian in east Serbia (Milovanovic, 1935).

description: Evolution of bichromatic waves represents a substantial interest in fluid mechanics, oceanography and maritime engineering, as well as in other fields of physics. In this presentation, evolution of surface water waves will be considered in the context of how close the bichromatic wave modes can be in the frequency/wavenumber space before the dynamics of their interactions changes, if it does. In this regard, the topic may be relevant across various applications for nonlinear waves in dispersive media. The study is conducted by means of the fully nonlinear one-dimensional model for gravity water waves by Chalikov & Sheinin. This approach is based on a non-stationary conformal mapping, which allows the equations of potential flow with the inclusion of a free surface to be written in a surface-following coordinate system. This transformation does not impose any restrictions on the shape of the surface, except that it has to be possible to represent this surface in terms of a Fourier series. The model accuracy and energy conservation within the evolving wave trains is very high, it is determined by the computer precision. We show that interaction of two monochromatic waves at the water surface enters a different dynamic regime if their wavenumbers become very close. Downshifting of the initial wave energy and growth of the first mode occur in the course of evolution of the two waves, depending on wave steepness and dk/k. Behaviour of these features change if dk/k<0.0025: both downshifting and growth rate become independent of dk/k, and the growth rates increases by orders of magnitude.

Material: One RV specimen (BBU-MPS-24083).
Description. Right valve conical, thick-shelled, having more than 50 mm length and 78 mm diameter antero-posterior and 55 mm dorsoventral (Fig. 7h). The ornamentation consists in fine and rounded longitudinal ribs, 2 mm in thickness in the dorsal side. On the ventral side, dense, regularly folded growth lamellae can be seen, slightly ondulated in interband. The interband (Ib) is very wide, centrally depressed separating the radial bands Vb and Pb which are simple folds with almost the same amplitude (Fig. 7h). In transversal section, the ligamental ridge (L) is triangular at base, with 11 mm in length and its inner margin truncated. Anterior and posterior of the ligamental ridge are two small, oval cavities (Fig. 7i). The outer shell layer varies between 13 to 15 mm in thickness, having only 5 mm in ventral side in interband area. Cells of the outer shell layer are irregular polygonal, predominantly penta- and hexagonal (Fig. 7i).
 Remarks: Radiolites nouleti is a large radiolitid easy identifiable by its thick-shelled, large interband and dense folded growth lamellae.
Age and distribution: Santonian-early Campanian in Croatia (Polšak et al., 1982), Romania (Lupu, 1976); early Campanian in France (Bilotte, 1985), Hungary (Czabalay, 1982), Serbia (Milovanovic, 1935) and Spain (Vicens, 1992); late Maastrichtian in Spain (Bilotte, 1985).

Should there be Rage against the Machine? Testing the Routinisation Hypothesis with Individual Level Data

description: NEUJOBS Working Paper No. D4.4.3 Abstract:
The objective of this paper is to analyse the impact of routine on jobs using the European Working Condition Survey dataset. Statistics indicate that the share of routine jobs decreased between 2000 and 2010, from 49% to 43% of total jobs, consistently with the task-biased technological change theory by Autor et al. (2003). Yet, it is unlikely that the process consists of pure destruction: routine may affect workers also by hitting on wages either because they are not as productive and efficient as a robot would be, or because they share the dividend of their productivity with the owner of the technology. Results of the ordered logit estimation indicate that not only routine tasks are associated to a wage penalty, but also that in half of Western European countries this penalty increases over the decade. Results are robust to the definition of routine adopted.

Rumination, mood and cognitive performance

description: Rumination, defined as repetitive, recurrent and uncontrollable thinking, has been implicated in cognitive impairments, particularly dysexecutive function, in people with depressed mood, what is now critical is an examination of the link between rumination and cognitive impairment independent of mood. Rumination’s direct relationship to basic cognitive functions may help explain the stability of rumination, and how it predicts future episodes of depressed mood. Two experiments examined how trait and experimentally induced rumination, and negative mood relate to attention and inhibition at varying levels of cognitive load in non-depressed participants. Study 1 found trait rumination significantly predicted errors of attention when cognitive load was low or high, but not at a medium level. Trait rumination also interacted with frequency of task unrelated thoughts to predict performance. Negative mood significantly predicted errors of inhibition also when the cognitive load was low or high. Study 2 expanded on the first by including two additional measures of executive function. Results were replicated for the first study and showed a ruminative thought style predicted inhibition, reaction time and set shifting in the additional measures.
New Welfare State Models Based on the New Member States' Experience?

description: Abstract:
The paper is concerned with the issue of how the postsocialist new member states of the European Union fit into the established methodologies of worlds and varieties of welfare capitalism. The paper argues that the postsocialist welfare state is different from the welfare states of the old member states and does not resemble any of the four existing models as present in Europe. The welfare states of the EU-10 countries are much smaller than those in the western half of the continent and generally demonstrate much stronger emphasis on redistribution to prevent poverty. The EU-10 are also highly internally differentiated as a group. We describe dimensions of welfare states in the new member states along three dimensions: size of the social protection expenditure, redistributive nature of the social transfers and relative redistribution effects based on the ratio between the first two variables. The size, and indirectly the shape, of the welfare state in the new member states is associated strongly with two factors: the size of the shock undergone by each economy during the transition and ethnic heterogeneity, particularly with regard to clearly defined and marginalized minorities. Based on these findings, we suggest provisional division of the Central and Eastern European welfare states into five groups. The provisional typology is based on the three dimensions of the welfare state identified above and position of each group along these dimensions is associated with potential determinants discussed above.

The age of information in gossip networks

description: We introduce models of gossip based communication networks in which each node is simultaneously a sensor, a relay and a user of information. We model the status of ages of information between nodes as a discrete time Markov chain. In this setting a gossip transmission policy is a decision made at each node regarding what type of information to relay at any given time (if any). When transmission policies are based on random decisions, we are able to analyze the age of information in certain illustrative structured examples either by means of an explicit analysis, an algorithm or asymptotic approximations. Our key contribution is presenting this class of models.
