Investigating workplace exposure to mycotoxins is of the utmost importance in supporting the implementation of preventive measures for workers. The aim of this study was to provide tools for measuring mycotoxins in urine and airborne samples. A multi-class mycotoxin method was developed in urine for the determination of aflatoxin B1, aflatoxin M1, ochratoxin A, ochratoxin α, deoxynivalenol, zearalenone, α-zearalenol, β-zearalenol, fumonisin B1, HT2-toxin and T2-toxin. Analysis was based on liquid chromatography–high resolution mass spectrometry. Sample pre-treatments included enzymatic digestion and an online or offline sample clean-up step. The method was validated according to the European Medicines Agency guidance procedures. In order to estimate external exposure, air samples collected with a CIP 10 (Capteur Individuel de Particules 10) personal dust sampler were analyzed for the quantification of up to ten mycotoxins, including aflatoxins, ochratoxin A, deoxynivalenol, zearalenone, fumonisin B1 and HT-2 toxin and T-2 toxin. The method was validated according to standards for workplace exposure to chemical and biological agents EN 482. Both methods, biomonitoring and airborne mycotoxin measurement, showed good analytical performances. They were successfully applied in a small pilot study to assess mycotoxin contamination in workers during cleaning of a grain elevator. We demonstrated that this approach was suitable for investigating occupational exposure to mycotoxins.

According to statistical data in Poland, sexual acts of minors account for about 3% of all criminal acts committed by minors and nearly 20% of all acts from the catalogue of crimes against sexual freedom and morality. The main objective of the study was to attempt to develop and present characteristics of minors who commit rape with particular cruelty. Taking into account the way the perpetrators act, the motivational background and the circumstances of the crime. In particular, attention was paid to specific individual and family characteristics. Because it is not clear whether juvenile sex offenders are different from non-sex offenders. The aim of this article is an attempt to capture individual, family and environmental differences. The study was also intended to provide information about who the victims are. The study was conducted on the basis of empirical material from court cases in which the basis of liability was Article 1974 of the Penal Code, and the perpetrators or accomplices of the acts were minors who at the time of the act were over 15 years of age but under 17 years of age. The research material consisted of court case files that had been finally completed, including forensic psychological opinions prepared by court experts. Cases from 2015-2020 were analysed. The obtained results allowed to capture some specific features of families in which minors were brought up and the characteristics of juvenile sex offenders themselves. This article raises the difficult issue of juvenile responsibility for sexual crimes, indicates areas in which it is necessary to regulate interactions and areas of possible preventive impacts.

Defence Science and Technology Group (DSTG) Australia constructed and trialled a demonstrator to capture exhaust gas particulates from a large marine diesel engine as part of a novel mechanical condition monitoring system. Particulate capture occurred on borosilicate glass patches situated within the exhaust system of a refurbished engine undergoing run-in trials. Analysis of captured nano through to large scale particulates showed wear debris from particular engine components, and the surrounding soot groundmass contained elements from fuel and lubricating oil. Changes in the material captured over the trial duration indicated the ability to monitor changes in engine condition. Overall this trial demonstrated exhaust particulate capture as a method of monitoring the condition and combustion performance for marine diesel engines.

Capture myopathy is a condition that manifests after prolonged pursuit, entrapment, restraint, live-stranding and/or transport. Its effects are wide-ranging and often life-threatening. All wild animals are susceptible to this condition, though particular species seem to be predisposed. A diagnosis of capture myopathy revolves around the animal’s natural and individual history as well as any clinical signs, although, in many cases, a definitive diagnosis cannot be made or is only determined post-mortem. Successful management often relies on aggressive fluid support, pain management and physical therapy.

Hoy en día es una necesidad urgente con carácter social, de salud humana, ambiental e incluso política, asegurar el abastecimiento de agua a las ciudades y poblados de nuestro país. En el caso del Distrito Federal, esta ciudad cuenta con una geografía característica que permite cada año un aporte de agua de lluvia de casi 780 millones de m3 pero solo cerca del 13% de este volumen, se aprovecha. La naturaleza da ejemplos de cómo pueden ser diseñados los sistemas para capturar agua pluvial. Al proceso de estudiar las soluciones que la propia naturaleza ha adoptado se le conoce como biomimetismo y la biomimética es la tecnología que imita a la naturaleza. El objetivo de este trabajo fue copiar principios simples de la naturaleza para diseñar un sistema biomimético de captura y filtración de agua pluvial para casas particulares y unidades habitacionales. Para el diseño del captador biomimético se trabajó con materiales ligeros que no absorben agua sino que la conducen con rapidez a depósitos, debido a que se favorece el fenómeno de cohesión. De los estudios se obtuvo la impermeabilidad de los materiales, su resistencia al flujo y se calcularon los coeficientes de cohesión alcanzados, lo que indica que tanto la moléculas de agua se agrupan entre si y así se evita que se humedezcan los materiales captadores. Estos datos permitieron el diseño final de un primer prototipo.

This article argues that art education ought to be central to the struggle against contemporary capitalist fascism. The authors turn to the space and time of the studio as the unique contribution of art education to antifascist struggles. In particular, the pataphysics of the studio – including its emphasis on producing particulars, laws of exceptions, and impossible solutions – all set adrift the rigidification of desirous production under capitalist reterritorialization. In conclusion, the article offers an invitation to art educators to experiment with a particular studious practice the authors call “protocoling” in relation to racist stereotypes as a way to break apart fascist subjectivities and the capture of desire into paranoid assemblages.

La période actuelle est caractérisée par une abondance de données radar libres d'accès dont l'utilisation estencouragée et facilitée par les agences spatiales, ces dernières mettant gratuitement à disposition des utilisateurs des logiciels de traitement et d'analyse d'images. Parallèlement, plusieurs sites académiques ou institutionnels proposent des ressources explicatives (cours, tutoriaux, logiciels) sur des sujets généraux ou ciblés destinés à faciliter l'usage des images dans la plupart des domaines d'application.Dans cet article, nous souhaitons aborder et détailler un point particulier, celui de la correction des images, au travers des divers prétraitements logiciels proposés lors d'une séquence de géo-référencement-calibration des images. Cette séquence, qui couple des aspects géométriques et radiométriques, a pour objectif d'établir la correspondance entre les valeurs numériques pixellaires de l'image et les mesures physiques de coefficients de rétrodiffusion destinés à caractériser des états de surface. Cette calibration est, en particulier, indispensable pour pratiquer l'inversion de modèles physiques ainsi que la fusion d'informations issues de données multi-capteurs et/ou multi-temporelles. Après avoir présenté les aspects généraux touchant à la puissance mesurée au niveau du capteur et les divers facteurs influençant cette mesure, nous nous focaliserons sur la pratique utilisateur, en discutant d'une part des différents choix de coefficients beta 0, sigma 0, gamma 0 offerts lors d'une calibration, et d'autre part de la prise en compte, ou non des effets de pente dans les corrections géométriques et radiométriques affectant l'image. Une attention particulière sera portée sur le coefficient gamma 0 dont les variations en fonction de l'incidence locale sont réputées très faibles dans le cas des forêts denses.

There is a conventional wisdom about the origin of public range management in the American west that draws most of its evidence logically, but nevertheless circumstantially, from decades of subsequent policy. It is shared by advocates across the political spectrum, from conservative elected officials and ranchers to radical environmentalists. That conventional wisdom distracts the many individuals who have attempted to understand range policy, and it hampers recent attempts at range policy reform. Narrowly, the conventional wisdom concludes that the institutionalized management privilege of cattle ranchersover all other users—the capture of range management—was according to the design of the Taylor Grazing Act of 1934. In so concluding, the conventional wisdom contributes to the more general idea that forces are at work to make the colonization of a policy area by a particular interest the inevitable result of politics in a liberal democracy.

Small mammal community structure was investigated at a semi-arid mallee site in the Middleback Ranges of South Australia during 14 field trips conducted over four years. During this time, 291 small mammals were caught from 6579 trap nights (trap success 4.4%). Ningaui yvonneae was the most abundant and frequently recorded species (199 captures), followed by Cercartetus concinnus (75 captures). Other species caught infrequently were Sminthopsis dolichura (2 captures), Notomys mitchellii (3 captures), Pseudomys bolami (2 captures) and Mus domesticus (10 captures). Ningaui yvonneae was the only species caught during all sampling periods. Males were trapped more frequently than females (117 : 43). Recapture rates were low, with only eight of 160 individuals caught during more than one sampling period. This may reflect the mobility of the species. Distances moved between successive recaptures within a sampling period averaged less than 100 m, while between sampling periods distances averaged more than 450 m. This is the first published study to capture N. yvonneae regularly and in reasonable numbers.

We review the tidal capture process and in particular the chaotic orbital evolution which follows capture. We discuss the formation of low-mass X-ray binaries in globular clusters via tidal capture and speculate on the possibility that some field low-mass X-ray binaries were formed this way in open clusters which have since dispersed, or in existing old open clusters which are not accessible to observation because of obscuration by dust or because they are indistinguishable from the rich background of galactic stars.

Abstract Metal fibrous felt particulates filter has the advantages of high mechanical strength, long service life, large dust capacity, high filtration accuracy, low resistance loss and high temperature resistance. In order to obtain the influence of structural parameters of metal fibrous felt on the characteristics of steady-state filtration efficiency, the effects of structural parameters of filter material such as porosity, fiber felt thickness and fiber diameter on steady-state capture efficiency under different filtration speeds are theoretically calculated and analyzed by using numerical calculation method. The results show that the structural parameters have an important impact on the steady-state filtration efficiency, which must be controlled within a reasonable range. Reducing the surface filtration speed to less than 0.1m/s can effectively improve the filtration efficiency. This paper provides a theoretical basis for the selection of structural parameters of metal fiber felt filter material, and has important research value.

Abstract Several factors guide our attention and the way we process our surroundings. In that regard, there is an ongoing debate about the way we are influenced by stimuli that have a particular self-relevance for us. Recent findings suggest that self-relevance does not always capture our attention automatically. Instead, an interpretation of the literature might be that self-relevance serves as an associative advantage facilitating the integration of relevant stimuli into the self-concept. We compared the effect of self-relevant stimuli with the effect of negative stimuli in three tasks measuring different aspects of cognitive processing. We found a first dissociation suggesting that negative valence attracts attention while self-relevance does not, a second dissociation suggesting that self-relevance influences stimulus processing beyond attention-grabbing mechanisms and in the form of an “associative glue,” while negative valence does not, and, last but not least, a third dissociation suggesting that self-relevance influences stimulus processing at a later stage than negative valence does.

Margaret Gatty was a skilled seaweed collector. Her large worldwide collection currently housed at St Andrews University Herbarium and another significant collection (of both seaweeds and marine invertebrates) held at Museums Sheffield are evaluated for the first time. These collections have remained largely un-curated, but assessment and data capture of their holdings is currently under way. Mrs Gatty acquired great skill and expertise as a collector and student of seashore flora and fauna, so much so that a number of taxa were named after her. Her daughter, Horatia, followed her mother but specialised in marine invertebrates, amassing a large collection, the bulk of which is divided between Sheffield and the Natural History Museum, London. An appendix of taxa associated with Mrs Gatty is included.

Resumo:

The key challenge of multi-domain translation lies in simultaneously encoding both the general knowledge shared across domains and the particular knowledge distinctive to each domain in a unified model. Previous work shows that the standard neural machine translation (NMT) model, trained on mixed-domain data, generally captures the general knowledge, but misses the domain-specific knowledge. In response to this problem, we augment NMT model with additional domain transformation networks to transform the general representations to domain-specific representations, which are subsequently fed to the NMT decoder. To guarantee the knowledge transformation, we also propose two complementary supervision signals by leveraging the power of knowledge distillation and adversarial learning. Experimental results on several language pairs, covering both balanced and unbalanced multi-domain translation, demonstrate the effectiveness and universality of the proposed approach. Encouragingly, the proposed unified model achieves comparable results with the fine-tuning approach that requires multiple models to preserve the particular knowledge. Further analyses reveal that the domain transformation networks successfully capture the domain-specific knowledge as expected.1

The presence of a large number of boron atoms in boron clusters make them attractive tools for the treatment of cancer using boron neutron capture therapy (BNCT). Since the quantity of boron atoms present in the target cell directly affects the effectiveness of BNCT, the idea of gathering a high number of boron atoms in a single entity has emerged many years ago. In this perspective, using hyper-branched macromolecules such as dendrimers appears as an interesting solution. In this review, we will first present the synthesis of diverse dendritic entities (dendrimers, dendrons, and Janus dendrimers) that incorporate boron clusters, in particular carboranes, anywhere in their structure. Four parts of this review present the synthesis of dendrimers having boron clusters on the surface, or inside their structure, of dendrons and of Janus dendrimers, bearing boron clusters. Practically all these boronated dendritic structures were synthesized with the objective to study their biological properties, but in fact only a few of them have been tested against cancerous cells, and even a smaller number was tested in BNCT experiments. The biological experiments are discussed in the fifth part of this review. A good efficiency is generally observed with the boronated dendrimers, even in animal models, with an increase in their mean survival time (MST).

This essay focuses on the genre of pilgrimage photography as it developed over the course of the twentieth century in the holy city of Mashhad, Iran. Photographs made during pilgrimages to the shrine of Imam Riza count among the most popular vernacular genres of Iranian photography. Pilgrimage photographs should be understood as sacred photo-objects, at once signifiers and carriers of piety. Once framed and taken home by pilgrims, they not only capture and memorialize the sacred encounter, but also carry the aura of the divine into the mundane space and time of the everyday. I focus on the particular visual language of these sacred photographic objects; a visual language achieved through costumes, gestures and body language, through painted backgrounds with symbolic themes. Second, I consider the kind of cultural work and pious affect they elicit as image-objects when placed in pilgrim’s homes. I end by briefly considering the recent changes and continuities brought about by digital imaging technologies.

Esta pesquisa exploratória teve como objetivo captar as percepções de adolescentes matriculados em estabelecimentos educacionais do Distrito Federal sobre as violências nas escolas e nas comunidades. Considerando que a literatura constata que as violências são comuns às escolas públicas e particulares, embora com diferentes ocorrências, o trabalho focalizou em particular as diferenças entre alunos dos dois tipos de escolas. Para tanto foi utilizada a técnica de grupos focais.

AbstractWe discuss the interplay of gravity and radiation in a static, spherically symmetric spacetime. Because of the spacetime curvature, balance between radiation pressure from spherical star and effective force of gravity may be established in a particular distance from the star surface, on so-called Eddington capture sphere. This is in contrast with the Newtonian scenario, for which Eddington luminosity of the radiation assures gravity-radiation balance at any radius. We explore properties of this relativistic equilibrium and the dynamics of test particles under radiation influence in the strong gravity regime.

This paper draws on extended life story oral history interviews with scientists who, beginning in the 1980s, turned to writing popular books, making radio and television programmes and taking to the stage for public lectures and debates, with relations between science and religion often a key topic: Peter Atkins, Nicholas Humphrey, Steve Jones, John Polkinghorne, Russell Stannard and Lewis Wolpert. I show that these interviews capture aspects of motivation and experience missed in much existing work on popular science. Stressing historical and individual particularity, I argue that what these scientists say about their decisions, aims and rewards should make us question a strong tendency in recent scholarship both to regard popular science as part of scientific work in general, and also to read the outcomes of popular science – such as advocacy for science or the promotion of certain theories – as the motivations for its production.

HighlightRay capture worldwide using variety fishing gear.Efficiency of fishing gear used in capture ray species among countries.The maturation size for female and male ray according to species present.Bycatch issues of elasmobranch in small and large scale fisheries.Suitable fishing gear to capture ray species at particular country.AbstractA coral reef is one of the important ecosystems. However coral Gillnets are usually used as a fishing gear by an artisanal fishery in Malaysia. This gear is commonly used by most countries. This paper discussed the rays capture worldwide by using a variety of fishing gear and also bycatch issues that commonly happen. The efficiency of the fishing gear used in capture ray species is compared and discussed among the countries. This paper distinguishes the maturation size for the female and male ray according to the species presence. The bycatch scenario is also discussed as the majority of this elasmobranch (shark and ray) which is caught as bycatch in both small scale fisheries (gill nets, long lines and hooks) and large scale fisheries (bottom trawl and purse seine). This paper explains the suitable type of fishing gear to use to capture ray species in a particular country.

Innovation at work is mainly driven by employees' ideas. This paper reports a study of the effectiveness (e.g., rate of suggestion making) of schemes for capturing these ideas. Based on a survey of 182 UK organizations, the study shows that decentralized suggestion schemes and work-based systems are more effective than centralized and informal schemes. The extent of planning, publicity, feedback and management support given to the scheme, and the type of reward offered to employees, also independently account for variation in effectiveness. Publicity and non-monetary rewards, though, are found to be most decisive, regardless of scheme type. Learning culture also affects the rate of suggestion making, though the effect is greater for centralized and decentralized schemes than for the others. The key implication of the findings is that by paying particular attention to how they are advertised and how participation is rewarded, organizations could improve the return on their idea capture schemes.

Until three or four decades ago, humanity was no longer constrained by the depletion of certain natural resources (especially energy) and the intensified degradation of the natural environment. The consequences of these major crises—such as the economic, financial, and social upheaval of the world, dramatic climate change, and the entry of politics into a Brownian sarabande—necessitate the transition of civilization to another viable formula. Adequate, timely, and sustainable solutions are being sought, from the subsistence ones to those of economic efficiency. Thus, the mobility revolution is credited as one of the most important levers of change. Starting from the reality that most cars in traffic are not occupied at their maximum capacity, some ideas have already been advanced and even put into practice—“inspired”—which would improve the efficiency in this regard. For example, the reduction in the number of seats in cars and, correspondingly, the considerable reduction in the dimensions of cars are already found in the design of mini-cars and the correlation of identical interests of the self-movement of several people and the integration of this coincidence in a single concurrent mobility formula is already functional through the ride sharing system. Along with intelligent mobility management and the transition to electric and autonomous mobility, streamlining the occupancy of moving cars is seen as a great potential of the mobility revolution. Within the limits of the methodology of data collection in economic statistics, this study proposes a complex technique associated with a convincing tactic of empirical measurement of specific indices of urban traffic issues. The special method is characterized by the simultaneity and plurality of observation points followed by the correlation of the values obtained from the measurement thus performed, with the results from the video recordings taken at the same time. This method will increase the methodological accuracy of data collection in economic statistics. By advancing this method, this study aims to capture the occupancy rates of people in urban vehicle traffic, in different cities, using a combined method.

Resumo:

Coordination of the complete capture sequence of the praying mantis has been studied in detail using several specially developed photographic techniques. The mantis was able to attack prey throughout a large three-dimensional capture zone by changing body orientation relative to its perch. This orientation centred prey on the median plane and brought it within an attack zone relative to the prothorax. Alignment with the median plane simplifies the attack since the prey can then be localized using only two dimensions. The attack comprised several stereotyped components which together formed a single movement sequence of all six legs. Although too rapid for visual feedback, a simple mechanism permits steering of these movements to capture prey at particular locations within the attack zone. These findings are contrasted with those from studies of mantis visual behaviour and a simple mechanism is suggested for how prey location is encoded to produce steering of the attack.

The male-specific bacterial virus MS2 is being used in this study to investigate the mechanisms of virus capture from aqueous suspension by a polypropylene microfilter. Mechanisms being studied include 1) adsorption of viruses to clean, unused filters; 2) adsorption of viruses to used filters; 3) capture of particulates formed from virus complexation with organic or inorganic materials; and 4) entrapment of viruses by a barrier layer generated by these materials on the outer surface of the filter. Batch studies were conducted using chopped filter material to quantify virus adsorption to unused filters. Identical studies are planned to examine used filters. Constant pressure studies using manufactured filter modules will be performed to assess the importance of complexation and barrier layer formation. Ranges of values of solution pH and ionic strength are to be examined in combination with varied concentrations of inorganic suspended solids, organic suspended solids and dissolved organic material to determine method and extent of virus capture. Initial data show adsorption directiy to an unused filter surface to be negligible between pH3 and pH10. Data is being collected to quantify the relative contribution of each of the other three mechanisms.

Until recently, the United Nations and regional systems of human rights protection had shown considerable reluctance to address human rights violations resulting from corruption. Instead, these actors would underline the negative impacts of corruption on human rights without identifying corruption itself as a violation of human rights. Since 2017, however, this has begun to shift. The UN, regional human rights institutions, and civil society have begun to devise concrete ways for human rights institutions and instruments to better contribute to the fight against corruption. The Inter-American Court of Human Rights (“the Court”), in particular, has taken preliminary steps to establish a legal link between corruption and human rights violations.

Urban hedgerows can act as barriers to roadside particulate air pollution, but details on methodologies to quantify pollutant capture, most efficient species to use, and practical planning advice are still evolving. We aimed to compare three widely used approaches to quantify particulate accumulation and deposition, and to ascertain the most cost-effective and robust approach for the rapid screening of various types of hedges. Secondly, using the most efficient methodology, we screened the summertime deposition of particulates on roadside hedges in Reading (UK), not just on species with differing leaf surface characteristics, but also along a transect of the hedge depth. Finally, we also compared particles’ capture by hedge leaf surfaces in locations with different traffic intensities, to try and ascertain the extent of reduction of particles’ concentration in various hedge types and urban locations. Results suggest that the gravimetric determination of particulate capture was most rapid and cost-effective, while being least technically demanding. We confirmed that hairy and more complex leaves captured most particulates, particularly in the >10 μm range. However, species choice only had a significant impact on the extent of capture on major roads, where the pollutant concentrations were highest. Furthermore, only hedge depths in excess of 2 m were found to noticeably reduce the concentration of fine particles in species with less capacity for particulates’ capture. Findings complement the growing body of knowledge to guide urban and landscape planners in choosing the most appropriate species to mitigate air quality in various urban contexts.

Neutron-capture reactions on gadolinium isotopes play an important role in several fields of physics,in particular in nuclear Astrophysics for the understanding of the nucleosynthesis of heavy elements (beyond iron) in stars via the s- and r-processes [1] and in nuclear technology. Another important application of gadolinium is linked to the production of terbium, that offers a set of clinically interesting isotopes for theranostics, characterized by complementary physical decay characteristics. In particular, the low-energy β −emitter terbium-161 is very similar to lutetium-177 in terms of half-life (6.89 d), β − energy and chemical properties. Being a significant emitter of conversion/Auger electrons, greater therapeutic effect can therefore be expected in comparison to Lu-177 [2, 3]. For this reason, in the last decade, the study of the neutron capture reaction 160Gd(n,γ)161 Gd and the subsequent β − decay in terbium-161 is getting particular attention. As the nuclear data on the Gd-160 neutron capture reaction are quite scarce and inconsistent, a new measurement of the capture cross section of Gd-160 at the CERN neutron Time-Of-Flight facilty was performed in order to provide high resolution, high-accuracy data on this important reaction, in the energy range from thermal to hundreds of keV. In this contribution, the preliminary results of the n_TOF measurement are presented.

What are the consequences of implementing Lecture Capture technology and how does it support students, especially those who are ‘hard to reach’? There is growing evidence about the benefits to students that lecture recordings provide and, in particular, about how they can directly support specific groups of learners. However, it is not easy to balance the needs of students with academic concerns, technological barriers and policy issues which need to be overcome. This piece presents the author’s views, having supported the wide-scale use of lecture capture technology since 2008.

Marker-based Optical Motion Capture (OMC) systems and associated musculoskeletal (MSK) modelling predictions offer non-invasively obtainable insights into muscle and joint loading at an in vivo level, aiding clinical decision-making. However, an OMC system is lab-based, expensive, and requires a line of sight. Inertial Motion Capture (IMC) techniques are widely-used alternatives, which are portable, user-friendly, and relatively low-cost, although with lesser accuracy. Irrespective of the choice of motion capture technique, one typically uses an MSK model to obtain the kinematic and kinetic outputs, which is a computationally expensive tool increasingly well approximated by machine learning (ML) methods. Here, an ML approach is presented that maps experimentally recorded IMC input data to the human upper-extremity MSK model outputs computed from (‘gold standard’) OMC input data. Essentially, this proof-of-concept study aims to predict higher-quality MSK outputs from the much easier-to-obtain IMC data. We use OMC and IMC data simultaneously collected for the same subjects to train different ML architectures that predict OMC-driven MSK outputs from IMC measurements. In particular, we employed various neural network (NN) architectures, such as Feed-Forward Neural Networks (FFNNs) and Recurrent Neural Networks (RNNs) (vanilla, Long Short-Term Memory, and Gated Recurrent Unit) and a comprehensive search for the best-fit model in the hyperparameters space in both subject-exposed (SE) as well as subject-naive (SN) settings. We observed a comparable performance for both FFNN and RNN models, which have a high degree of agreement (ravg,SE,FFNN=0.90±0.19, ravg,SE,RNN=0.89±0.17, ravg,SN,FFNN=0.84±0.23, and ravg,SN,RNN=0.78±0.23) with the desired OMC-driven MSK estimates for held-out test data. The findings demonstrate that mapping IMC inputs to OMC-driven MSK outputs using ML models could be instrumental in transitioning MSK modelling from ‘lab to field’.

Through the use of language, government institutions and officials in elective democracies try to present particular instances of abuse of power and public resources as legitimate and enable similar practices in the future. This article aims to identify and reveal the strategies used within the Western Balkans' official discourses to legitimize particular cases of suspected state capture and assess their outcomes. The empirical study of six prominent cases of suspected state capture in the construction industry in the period from 2010 to 2020 indicates that a single legitimization strategy is used region-wide, and this article contributes to better understanding it. To assess the strategy outcomes, an original analytic model is proposed. The findings suggest that the deployment of the strategy to legitimize the suspected cases of state capture encourages potential captors in the region to consider engaging in similar practices in the future.

Abstract Movements of 11 female and 1 male adult Peregrine Falcons (Falco peregrinus) wintering in coastal Gulf of Mexico, Tamaulipas, Mexico, were monitored with satellite-received transmitters (PTTs), 1997–1998. Median areas for minimum convex polygon winter home ranges at 50% and 90% levels (both years) were 1173 and 8311 ha, respectively. Most birds left wintering grounds in the first week of May. Duration of northward migration averaged 30 days. Distances between capture location and summer settling place were between 4580 and 5844 km; birds traversed 40.4–46.4 degrees of latitude. Birds summered between far western Canada and coastal west Greenland. One was followed to the same summering ground in both years. Autumnal migration routes were through the middle of the continent, and initiated in August and September. Falcons arrived on wintering grounds in September and October, averaging 40 days to make the journey. PTT data and capture locations of birds trapped in more than 1 year suggest fidelity to wintering areas, although perhaps not particular winter home ranges. Migración y Áreas de Ocurrencia de Halcones Peregrinos Invernantes en la Costa del Golfo de México, Tamaulipas, México Resumen. Entre 1997 y 1998, se monitorearon con transmisores de satellite (PTTs) los movimientos de 12 halcones peregrinos adultos (Falco peregrinus; 11 hembras y 1 macho) invernando en la costa del Golfo de México, Tamaulipas, México. Se utilizaron niveles de precisión del 50% y 90% en los polígonos mínimos estimados para describir los hambitos hogareños de invernada (en ambos años); éstos fueron de 1173 y 8311 ha, respectivamente. La mayoría de las aves abandonaron las areas de invernada en la primera semana de mayo. La duración de la migración hacia el Norte promedió 30 días. Las distancias entre los lugares donde las aves fueron capturadas y donde se establecieron en el verano variaron entre 4580 y 5844 km; así que éstas recorrieron entre 40.4 y 46.4 grados de latitud. Los halcones pasaron el verano entre el lejano oeste de Canadá y la costa oeste de Groenlandia. Uno de ellos fue seguido en ambos años hasta la misma área de veraneo. Las rutas migratorias del otoño tuvieron lugar a través del centro del continente y se iniciaron en agosto y septiembre. Los halcones peregrinos llegaron a las áreas de inviernada en septiembre y octubre, promediando 40 días para hacer el recorrido. Los datos de los PTTs e información sobre las ubicaciones de los lugares de captura de las aves atrapadas en más de un año sugieren fidelidad a las áreas de invierno, pero tal vez no a hambitos hogareños particulares.
