The article discusses the legacy of Protestantism in Poland and the Protestant collections preserved in museum institutions in Poland. The author presents the collections of Evangelical artefacts amassed in various ways and forms and at different times, which thus constitutes a preliminary typology of the legacy of the Reformation. For simplification, she defines Evangelical objects as all objects which are part of the broadly-understood Protestant legacy. The spectrum of these objects is very broad, ranging from artefacts in traditional museum institutions, through sacred places, works of art, technical monuments, ephemera, cemeteries, to virtual collections of audiovisual and digitised legal instruments. The examples quoted in the text do not exhaust the subject, but evidence the vastness and richness of the legacy acquired as a donation after the Reformation movement initiated by the Augustinian monk Martin Luther.

Abstract Art market has been developing in Poland and the first Art Fund was established in 2011. Therefore it seems that investment in art can be considered as alternative form by Polish investors. In order to decide whether art is a good investment, it is necessary to evaluate expected returns which might be obtained from such investment thus an art price index should be developed. The aim of the paper is to discuss artworks as investment assets and evaluate price index of paintings produced by 11 Polish artists whose artworks were traded the most often on auctions that were held in Poland in the years 2007–2010. In our research, employing data concerning 750 objects, we apply the hedonic index methodology to estimate returns from the paintings market. The results of our investigation show that hedonic quality adjustment essentially influences evaluation of artwork prices therefore we propose the aggregated hedonic index which might better describe situation at the art market than the hedonic index biased by the specification of a single model.

In response to the ECPRD request, the Bureau of Research provided the requester with information on restitution of cultural heritage goods. According to the author, the return of cultural goods acquired from a foreign country during a war or colonization is regulated in the Polish Act on Restitution of National Cultural Goods, which governs the implementation of the Directive on the return of cultural objects unlawfully removed from the territory of a Member State. The Republic of Poland was requested by Germany to return certain cultural goods, confiscated after World War II. However these requests were turned down because the goods were acquired as a result of the change of state borders. Before the above-mentioned Act came into force, the Polish state had returned some cultural goods to other countries. The Polish Ministry of Culture and National Heritage has a special unit which deals with restitution of artworks and keeps the Catalogue of the War Losses - The Division for Looted Art.

Summary The article focuses on the historical link between herbalism and art at the turn of the twentieth century. The aim of this investigation is to recognize medicinal plants shown as symbols in Polish painting between 1890 and 1914 and find some cultural context of their presence in artworks. In this qualitative study online art galleries and museum collections were analyzed to select Polish symbolists’ artworks including plant images. Next, their botanical classification and medicinal context were examined. Twenty wild-growing plant species were recognized. Some of them had been used in traditional medicine (Alcea rosea, Angelica archangelica, Artemisia abrotanum, Betula pendula, Carduus marianus, Convallaria majalis, Crocus sativus, Lilium candidum, Matricaria chamomilla, Nuphar lutea, Paeonia officinalis, Papaver somniferum, Pelargonium hortorum, Populus nigra, Primula veris, Sorbus aucuparia, Taraxacum officinale, and Verbascum thapsus) and two species grown in the Carpathians (Digitalis purpurea, Lilium bulbiferum) at the time. Used to paint realistic objects, the symbolists made free-hand drawings in nature and in this way they recorded some wild-growing plants typical for surroundings of the town of Cracow and the Carpathian Mountains. Artistic images of plants were not intentionally aimed at taxonomic identification, however, sometimes classification was possible.

Before the outbreak of WW II, the works of world art collected at the Wilanów Palace were considered to be the largest private collection in the Polish territories. Just the very collection of painting featured 1.200 exhibits. Apart from them the Wilanów collection contained historic furniture, old coins, textiles, artistic craftsmanship items, drawings, and prints, pottery, glassware, silverware, bronzes, sculptures, as well as mementoes of Polish rulers. Already in the first weeks of the German occupation, assigned officials selected the most precious art works from the Wilanów collections, and included them in the Sichergestellte Kunstwerke im Generalgouvernement Catalogue. The publication presented the most precious cultural goods secured by the Germans in the territory of occupied Poland. It included 76 items: 29 paintings and 47 artistic craftsmanship objects. In 1943, the majority of the works included in the quoted Catalogue were transferred to Cracow. A year later, the most valuable exhibits from Wilanów were evacuated to Lower Silesia. What remained in Cracow was only a part of the collection relocated from Wilanów. The chaos of the last weeks preceding the fall of the Third Reich caused that many art works from the Wilanów collection are considered war losses. Among many objects, included in the above Catalogue, there are several Wilanów paintings: Portrait of a Man by Bartholomeus van der Helst, Portrait of a Married Couple by Pieter Nason, Allegory of Architecture, Painting, and Sculpture by Pompeo Batoni, Allegorical Scene in Landscape by Paris Bordone, and The Assumption of Mary by Charles Le Brun.

ABSTRACTThis study tested whether individual sensitivity to an auditory perceptual cue called amplitude rise time (ART) facilitates novel word learning. Forty adult native speakers of Polish performed a perceptual task testing their sensitivity to ART, learned associations between nonwords and pictures of common objects, and were subsequently tested on their knowledge with a picture recognition (PR) task. In the PR task participants heard each nonword, followed either by a congruent or incongruent picture, and had to assess if the picture matched the nonword. Word learning efficiency was measured by accuracy and reaction time on the PR task and modulation of the N300 ERP. As predicted, participants with greater sensitivity to ART showed better performance in PR suggesting that auditory sensitivity indeed facilitates learning of novel words. Contrary to expectations, the N300 was not modulated by sensitivity to ART suggesting that the behavioral and ERP measures reflect different underlying processes.

Full textAbstract:
The article is an attempt to present the semantics of marble in the sacred Polish sculpture of Romanticism. Taking as its starting point the modern theory of art, it first emphasizes the special role of white marble in modern sculptural theory and practice, and then outlines the foundation of this judgment in the art of the classicist era, especially in the theory of J.J. Winckelmann. Together with the spread of classical tastes, the significance of this view for Polish modern sculpture is shown, in which, in accordance with Winckelmann’s taste, white marble was perceived as the noblest raw material, worthy of the images of the gods. In the Romantic era, following G. W. Hegel, marble was regarded as “spiritual” stone, the most suitable for the depiction of the sacred. This was expressed in the theory and practice of sculpture by such artists as Cyprian Norwid and Teofil Lenartowicz, who went to Rome – the capital of sacred art – to sculpt in this material. They were followed by other Polish sculptors who also went to Rome to work in marble. The article shows their struggles, which ended successfully only for T.O. Sosnowski. In his works, however, white marble from “animate” stone went on to become material suitable for making repetitive compositions in the spirit of Italian Purism. Marble evolved from being material suitable for the representation of gods to one used for commercial objects, which was perfectly illustrated by Norwid in his short story „Ad leones!”

Full textAbstract:
The text is a commentary to the phenomena in Polish modern art in the final years of the 20th century. It constitutes a “first-hand” account by a participant of the events and the host of the location. The location was the author’s private workshop in the attic of a Łódź tenement house in the very centre of the city, in the circles of artists creating situations, meetings, events and objects, which established Kultura Zrzuty [the Whip-round Culture], a phenomenon which described the activities of artists independent of state institutions and officials patrons in the 1980s. The analysis of the events within the area of independent Okolice Sztuki inspired the author to discuss the form of other artists and his own, who created art in Strych [literally: attic] in an unchanging conflict between physical and social existence and freedom in art.

Full textAbstract:
The painting of the matter was an important component of Polish art of the “thaw” period and the 1960s. So far Polish art historians have usually interpreted works made of non-traditional substances by Polish artists as examples of inspiration by Western art and a tendency to abandon the painting as such. Scholars and critics stressed the relief qualities of art objects and their impact on the spectator through the surface texture and the properties of the material used, often incorporated into a picture directly from reality and provoking specific associations. Such an approach did justice only to some such works, e.g., those painted with paints mixed with nonpainterly substances, with the mud effects of the palette, characteristic of French art (Aleksander Kobzdej, Jan Lebenstein), or abandoning traditional materials to challenge the painting as such (Jan Ziemski, Włodzimierz Borowski, Jerzy Rosołowicz). Thus far the reflection on the painting of the matter seems inadequate to the works in which paint was eliminated in favor of other materials and substances combined with painterly activities. Those unspecific substances and materials were often distributed on flat surfaces and composed in terms of basic division of the pictorial field, its main axes, relations to the edges, etc. Such “paintings made of matter” are interesting examples of the “thaw” art, which have not been interpreted as paintings, escaping chronological and other criteria of art history. Ambiguously called the “painting of the matter,” they occupied the margins of the critical discourse. The inadequacy of the terms adopted to describe them resulted in ignoring many works, while others have been included in the history of Polish art only in some aspects. So far no one has addressed the basic question of different artistic responses to the problem of searching for the limits of the painting, and related attempts to enhance the painterly idiom which was at the same time disrupted in a number of ways. The author analyzes works selected from the set of about three hundred items found in thirteen Polish museums. Regardless of the individual differences, the paintings by Jadwiga Maziarska, Bronisław Kierzkowski, Adam Marczyński, Teresa Rudowicz, and Krystyn Zieliński exemplify the combination of non-traditional substances and surface composition. Paradoxically, the decision to abandon paint did not make those artists deny the superior role of the surface, which resulted in the creation of works oscillating among painting, relief, and sculpture, close to collages or assemblages, yet quite specific. Their works either exploited the conditions offered by the framed flat surface or brought into play new, autonomous surfaces.

Full textAbstract:
This thesis seeks to contribute to the knowledge base about social policy in the United States, using long-term care (LTC) financing policy reform as an illustrative example. Specifically, this thesis explores LTC financing reform efforts during three U.S. Presidential administrations: Bill Clinton (1993-2001), George W. Bush (2001-2009), and Barack Obama (2009-2010). Within this historical framework, the LTC provisions of the Health Security Act of 1993, the development of the Community Living Assistant Services and Supports or 'CLASS' Act during the Bush Administration, and the legislative success of the CLASS Act as a part of the Patient Protection and Affordable Care Act of 2010 provide comparable cases to compare the drivers of social policy. Drawing on the explanatory frameworks of the welfare state such as ideology, historical institutionalism, and an actor-centered approach to policy analysis, this thesis argues that successful path-departing legislation is difficult to achieve due, in part, to the presumed high costs of social programs and the complex institutional framework of the American political system. Policy outcomes result from the interaction between the complex processes and dynamics of the political system through which policy change (or the failure to change) actually occurs. The fact that the CLASS Act was politically successful, yet administratively inoperable as designed, reinforces the argument that social policy outcomes in the United States are reflective of a complex, enduring struggle of competing ideologies. This continual struggle, coupled with a heightened concern over cost control and fiscal austerity, helps to ensure that policies which are legislatively successful within the institutional architecture of the American political system are unlikely to produce major expansions of the welfare state. Social change is therefore highly difficult to achieve, even in the face of significant unmet social needs. Comprehensive reform of U.S. LTC financing arrangements will remain an elusive goal for the foreseeable future. Instead, incremental, highly pro-market solutions are likely to be the types of policies promoted in the years of ahead.

Full textAbstract:
Congressional reform is the focus of my study. Congress (but primarily the House of Representatives) attempted to reform its workings from 1968 through 1975, so it might be more effective in developing comprehensive policies on national issues, and more independent of the executive branch. Reform raised expectations that the legislature would reassert its policy-making role, which had diminished during the preceding thirty years. My study examines the influence of these changes on the congressional decision-making process, including their impact on the important role played by external actors, interest groups and especially the President, who reacted to these changes. The study examines the process through an analysis of the development and passage of the most controversial provision, dealing with oil-price controls (Title IV), of Congress' major energy bill of 1975, the Energy Policy and Conservation Act (H.R. 7014). On 15 December 1975, Congress passed the Energy Policy and Conservation Act (EPCA) which President Gerald R. Ford signed into law on 22 December. The EPCA (Public Law 94-163) extended oil-price controls until 1979. The oilpricing provision had significant national and international economic and political implications. Merely to trace the tortuous chronicle of oil-pricing policy would be informative. But this study will go further by using this account to analyze congressional decision-making in the period immediately following Congress' attempts at reform. My study shows that although reforms eroded old norms and power centres, significantly altering some aspects of congressional decision-making (again primarily in the House), they did not create institutional mechanisms or distribute internal powers in such a way that Congress could independently initiate and develop comprehensive national policies. Congress remained more dependent on the President than many of its members understood. The final substance of the oil-pricing policy reflected the characteristic congressional decision-making process, which had become even more dispersed as it was democratized by reform. The committee system, without a strong executive or party control, divides issues in a way that limits decision-makers' options.

Full textAbstract:
Background Malnutrition is a major risk factor of infant mortality in India. Policies targeting poverty and food insecurity may reduce infant malnutrition. The Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), a wage-for employment policy of the Indian Government, targets deprivation and food insecurity in rural households. MGNREGA could prevent infant malnutrition by improving household food security or increase the risk of malnutrition by reducing the time devoted to infant care if mothers are employed. This study analyzed the effect and the pathways of effect of households' and mothers' participation in MGNREGA on infant malnutrition. Methods A community based mixed methods study using cross-sectional survey and focus group discussions (FGDs) was conducted in Dungarpur district of Rajasthan, India. Cross-sectional study included 528 households with 1,056 participants who were infants 1 to <12 months and their mothers/caregivers. Selected households were divided into MGNREGA-households and non-MGNREGA-households based on participation in MGNREGA between August-2010 and September-20ll. Anthropometric indicators of infant malnutrition-underweight, stunting, and wasting (WHO criteria) were the outcomes. Eleven FGDs with 62 mothers were conducted. Results Of 528 households, 281 participated in MGNREGA (53%). Mothers were employed in 51 (18%) households. Prevalence of wasting was 39%, stunting 24%, and underweight 50%. Households participating in MGNREGA were less likely to have wasted infants (OR 0' 57, 95% Cl 0•37-0'89; p=O'014) and underweight infants (OR 0'48,95% Cl 0•30-0'76; p=0'002) than non-participating households. Stunting did not differ significantly between groups. Although MGNREGA reduced starvation, it did not confer food security to the participating households because of lower than standard wages and delayed payments. Results from path analysis did not support an effect through household food security and infant feeding, but suggested a pathway of effect through birth-weight. Mothers' employment had no significant effect on the outcomes in the cross-sectional study, but the qualitative study indicated that it could compromise infant feeding and care. Conclusion Participation in MGNREGA was associated with reduced infant malnutrition possibly mediated indirectly via improved birth-weight rather than improved infant feeding. Providing child care facilities at worksites could mitigate the negative effects of mother's participation in MGNREGA. Further, improving mothers' knowledge of appropriate feeding practices in conjunction with providing employment (to address deprivation and food insecurity) is key in the efforts to reduce infant malnutrition.

Full textAbstract:
Foucault's 'governmentality approach' developed the notion of 'dividing practices' (1991; see Seddon 2007) which recognises that how individuals and groups are categorised determines how they are governed. This thesis draws on critical disability studies and criminological literature on 'doing justice to difference' to develop a disability perspective in criminology, in order to analyse the governance of offenders with autism. It argues that there is descriptive and normative value in proactively categorising these groups as 'disabled' under the 'social model' of disability. The social model of disability is helpful in enabling us to distinguish between impairment and disablement. It allows us to comprehend the 'psy' literature, which explores the link between the 'symptomatology' of autism and criminality (the 'impairment branch' of the distinction) in combination with the 'interconnecting variables' (Browning and Caulfield, 2011) which lead offenders with autism into the criminal justice system and their inequitable experiences (the 'disablement branch' of the distinction). This is timely given the entrenchment of this model in the Equality Act 2010 and the inception of the Autism Act 2009, Statutory Guidance (DOH, 2010; 2015) and related policy. Using cross-method triangulation of qualitative data collected through interviews with elites and practitioners, textual analysis and court observation of eight adult defendants with autism through their court process, this thesis investigates why the status of this group as disabled under the Equality Act 2010 has been overlooked in criminal justice policy and criminal court decision-making. It examines the extent to which policy-makers and criminal justice decision-makers consider the defendant's autism in their decision-making about the defendant's case in the courts. Finally, it examines the impact of 'collateral' effects of the criminal justice process on family members who supported these defendants.

Full textAbstract:
Inter-governmental organisations (IGOs) are given mandates by states to perform particular tasks: from refugee protection to the management of migration to promoting development. As new global challenges arise, such as climate change, these organisations must decide whether to ignore them or change in response. But what drives inter-governmental organisations to move beyond their mandates, if it is not their member states? International Relations offers a limited account of if and how they will respond to new issue areas. Principal-agent theory treats IGOs as units with fixed preferences to expand and maximise their tasks and scope (Hawkins et al. 2006; Nielson and Tierney 2003; Pollack 2003). Meanwhile, sociological institutionalism argues that IOs are driven by a logic of appropriateness and staff will only support expansion if it fits coherently with their organisational identity and culture (Barnett and Coleman 2005). I build on these two theories and propose that IGO behaviour should be explained by organisational type. IGOs exist along a spectrum from normative to functional ideal-types. Normative IGOs have supervisory status over a body of international law, seek moral legitimacy and follow a logic of appropriateness. Functional IGOs are projectised organisations which seek pragmatic legitimacy and adopt a logic of consequences. I illustrate how IGO type interacts with the status of the new issue area to determine the timing, nature and extent of organisational change. I focus on the responses to climate change of three inter-governmental organisations: the United Nations High Commission for Refugees, a normative organisation; the International Organisation for Migration, a functional organisation; and the United Nations Development Programme, a hybrid organisation. IGO type has important implications for IR scholars and policy-makers as we look to these institutions to provide global solutions to global issues such as climate change, migration, refugees and development.

Full textAbstract:
The financial provisions of the HE Act (2004) were intended to introduce market forces into the relationship between higher education institutions in England and their full-time Home/EU undergraduates. The policies that underpinned that legislation were established by Parliamentarians during a period of intense public and political debate which accompanied the passage of the Act and now, as suppliers in a nascent quasi-market, universities are de facto responsible for their delivery. With that market beginning to stabilise, this research compares those political objectives with observed outcomes of the introduction of the Act. Primary data has been collected through semi-structured interviews with key decision-makers in six sample universities – chosen to reflect both the spread of institutions in the sector and the range of pricing policies in operation – and with those involved nationally in shaping the legislation. From this material, supported by secondary quantitative and qualitative evidence, university pricing strategies are considered, in the context of theories of marketing and of higher education management, to provide an understanding of how institutions have structured their financial offerings with the aim of targeting specific markets for applicants. Data from the sample institutions is then used to build a profile of the quasi-market that the suppliers within it are generating. Even though members of the sample have taken diverse approaches to price-setting, there are some clear consistencies that typify this emerging national market: prices are set through adjustments to bursaries, not fees; and complex financial offerings have created barriers to effective communication. Furthermore, as institutional managers analyse the effects of their own pricing strategies locally, they are observing these trends and thus, where any changes are being made, these tend towards simplification of bursary schemes and hence increasing homogeneity across the sector. However, with the (index-linked) £3000 cap which currently applies to fees, it is increasingly apparent that the current quasi-market for full-time Home/EU undergraduates at English universities has not reached its price-sensitivity point and hence, this research argues, the market is not operating fully. Therefore, while this study offers an understanding of motivations behind current institutional actions and the nature of the resulting quasi-market, it also explains why it is not feasible to extrapolate from this information to forecast how the market might work were regulatory parameters to be changed significantly.

Full textAbstract:
This dissertation consists of three articles on social assistance benefit receipt dynamics in European countries. The first article presents an analysis of state dependence in benefit receipt in Germany based on annual survey data from the German Socio-Economic Panel. The observation period extends from 1995 to 2011, thus covering the 2005 'Hartz reforms'. I estimate a series of dynamic random-effects probit models to control for observed and unobserved heterogeneity and the endogeneity of initial conditions. The high observed state dependence has a substantial structural component, with benefit receipt one year ago being associated with an increase in the likelihood of receipt today by 13 percentage points. There is only little evidence for time-variation in state dependence. The second article presents evidence on spell durations and the frequency of repeat spells using monthly administrative data from Luxembourg, the Netherlands, Norway and Sweden. In the two Nordic countries, short-term benefit receipt is the norm, with only around 6% and 11% of spells in Norway and Sweden lasting longer than 12 months. Most recipients however have multiple spells. In Luxembourg and the Netherlands, long-term benefit receipt is frequent, with median spell durations of 14 and 9 months, respectively, and one-third and one-quarter of all spells lasting 24 months or longer. The total duration of benefit receipt across spells is much higher in the Netherlands and Luxembourg than in Norway and Sweden. The third article tests the validity of one of the central assumptions of dynamic discrete-choice models of benefit dynamics, the conditional Markov property. Using monthly administrative data from Norway, the article shows that the Markov property is violated as estimated state dependence is affected by the chosen time unit of analysis. The standard model can be improved by permitting for different entry and persistence equations and duration and occurrence dependence in benefit receipt.

Full textAbstract:
A major objective of the Human Rights Act (HRA) was to bring about a culture of rights in the UK. Its introduction fore-grounded questions about the use of rights to advance social justice issues and was the impetus for this research. At about the same as the Act came into effect another law, Section 55, an antithesis of what the HRA promised, was passed which forced thousands of asylum-seekers into destitution. Section 55 became a major battleground pitting non-governmental organisations (NGOs) against the Home Office in a three-year long campaign, characterised by rancour and viciousness, unlike any in recent memory. The NGOs, with the new HRA as a key part of their strategy, defeated the legislation. This thesis, a bottom-up case study of rights at work, examines the role of rights in the campaign to assess (1) if rights brought about social changes and (2) is a culture of rights developing in the UK? The paper first considers the various theoretical frameworks on rights and social change and analyses various case studies of rights at work. Context is important; therefore, it also examines how asylum has come to be framed in present-day discourse, with an overview on the evolution of welfare as a coercive measure. The study, framed against current events of the day, concludes that while test-case challenges eventually defeated Section 55 welfare as a coercive measure continues. In short, the HRA has proven to be ineffective against illiberal policies and the development of a culture of rights, insofar as asylum is concerned, has stalled.

Full textAbstract:
The late Victorian and Edwardian period saw ritual become increasingly important in political life. Towns and cities were involved in conscious efforts to construct and project attractive images of themselves. These images were intended to encourage a sense of civic patriotism. Ceremonies, honorific titles, public events and civic architecture were essays in the invention of tradition. However, historians have applied the concept of the invention of tradition unevenly. Previous research has dwelt on the construction of images. Perceptions of official images and responses to them have been overlooked. This thesis employs a model which recognises images as processes with foundaitons in human relationships. It evaluates images in terms of intentionality, power, context and participation. The participative dimension is of particular importance, because images aimed to instil a sense of civic patriotism which would encourage citizens to make emotional and financial investments in their communities. Liverpool attained the status of a city in 1880. The civic ideology of the city was dominated by images of commerce and by notions of Imperial duty and public service which celebrated commercial virtues. Many aspects of urban life were shaped by civic image. This study does not confine itself to public events and pageantry, instead it explores such spheres as municipal art policy, Liverpool's public health record, the attempts to extend the city boundaries, civic hagiography, the foundation of the University, women and the ideal of citizenship and the influence of football on civic identity to demonstrate the importance of images in the city's social, political and institutional history. The purpose of the thesis is three-fold: to suggest that civic image opens new perspectives on Liverpudlian history, to discover why there were more conscious attempts to construct civic image and to restore participation to the study of civic image by unravelling the connections between image and patriotism.

This thesis aims to provide a framework for analyzing the moral responsibilities of global agents in what I call the Global Health Crisis (GHC), with special attention devoted to the moral responsibilities of pharmaceutical companies. The main contribution of this thesis is to provide a general account of the moral responsibilities of different global players, mapping the different kinds of duties they have, their content and force, and their relation to the responsibilities of other relevant actors in the GHC. I also apply this account to current debates surrounding the need for reforms to the international legal rules addressing the GHC, notably the TRIPs regime. In doing so, this thesis will discuss the allocation of responsibilities for the GHC among different global players, such as state and non-state actors, the latter including pharmaceutical companies. In order to investigate the allocation of duties, I will first analyze the object of such allocation which constitutes the object of the current GHC (Part A); then the agents responsible for addressing this crisis (Part B); and finally, existing institutional alternatives to reform the international legal rules addressing the GHC, such as the TRIPs regime (Part C).

Full textAbstract:
AbstractThis chapter attends to how the concept of “communities of practice” (Lave and Wenger, Situated learning: Legitimate peripheral participation, learning in doing. Cambridge University Press, Cambridge, 1991) has been taken up by managers and policy makers in trans-local contexts. Although the concept was developed for co-located communities, it was transferred to distributed settings. In such settings, the sharing of practices is not necessarily active, and the performance of community not necessarily tied to their sharing. Some of the ambiguities of the original concept became problematic. The chapter is based on two vignettes that demonstrate how community is understood by policy makers and managers as a form of organisation that needs to be cultivated and coordinated. Continuing on the success of “communities of practice”, a focus of such striving became the sharing of experiences (and “good practices”) in order to foster community building. In a trans-local context, this meant—for the actors responsible for building community—a focus on how practices may be shared actively. One answer to this challenge was to describe local practices in standardised templates. However, different ways of organising the sharing of knowledge objects (e.g. who are the actors that define the structure of templates or how do they determine what counts as ‘good practice’) resulted in different forms of communality.

Full textAbstract:
There is a need for refining data security and privacy protection in virtual reality systems which are interactive, creative and dynamic, i.e. where at run-time mutually interactive objects can be added or removed in different contexts while their behavior can be modified. In virtual worlds of this kind, operations on particular objects either should or shouldn’t be allowed to users playing different roles with respect to inter-object interactions. In the VR-PR method presented in this chapter, where VR-PR stands for “Virtual Reality–Privilege Representation”, privileges are represented by pairs, each comprising an object and a meta-operation. Meta-operations are induced automatically from possible object interactions, i.e. generated using automatic analysis of the object method call graphs. Meta-operations reflect the method call scope admitted and are used in the process of creating and modifying privileges, which in turn is controlled by a validation mechanism. Expressive and flexible, privileges based on meta-operations are consistent with a set of objects composing a virtual world, as well as with the interactions between those objects, both interactions and objects permanently evolving. In this chapter it is shown in a series of use cases how the VR-PR approach can be applied to various types of object-oriented virtual worlds. The examples are followed by a broader discussion of the privilege lifecycle in the same virtual environment.

Full textAbstract:
It cannot be said that the creative biography of the artist-architect Stefan Narębski (1892–1966) remains a completely unknown page in the history of art, but everything that has been written and published so far about the life and work of Stefan Narębski is only the top of the iceberg which is his complete biography. The author restores many forgotten and unknown facts of this biography, mainly based on the materials of the Archive of the Nicolaus Copernicus University, first of all, the artist’s own notes (“Diaries”), which had never been published before. Discoveries of this kind relate primarily to the childhood and adolescence of Narębski, held in the Caucasus and Vilnius; his participation in the 1905 revolution; his educational and creative activities in Włocławek in the 1920s; his connections with Stephen Batory University; as well as the repressions that he faced both during the years of the Nazi occupation of Lithuania and during the restoration of Soviet power here, in 1944–45. In the artistic heritage of Narębski, a close-up is highlighted by the types of residential buildings developed by him, educational institutions (museum, school, university department), modern churches, projects for the artistic transformation and decoration of public interiors (the residence of the archbishop; town halls in Vilnius and Torun). The theoretical development of the artistic training program for masters of architectural design (design and decoration of interiors), carried out by Narębski, and the practical implementation of this program at the Nicolaus Copernicus University contained an innovative beginning and provided the most important breakthrough of Polish post-war artistic pedagogy towards a modern, progressive methodology. Of great importance is the international aspect of the work of Narębski, whose personal biography is connected not only with Poland and the strongest impulses of Polish patriotism, but also with Lithuania, Russia, Belarus, Ukraine (with the places where he studied, lived, worked, built and planned the construction of new objects). His contribution to the development of art and artistic pedagogy is subject to measurement on the scale of not only national but also Eastern European culture.

Full textAbstract:
The chapter discusses the art theories of Henri Focillon and Meyer Schapiro in order to explore the potential of an art history based on speculative realism. The focus lies on three basic positions in their writings, considered to be productive for the perspective of a speculative art history, as they transcend idealistic and language centered concepts of art history. First, both Focillon and Schapiro consider the artwork as an object with a reality of its own, causing things to happen. Second, both of them hold a relational and processual conception of the artwork: it is considered as a place of negotiation between human action, material and ideas. Thirdly, their materialistic and relational conception of the artwork is associated with a dynamic notion of form. These principals can be related to the speculative realist’s materialist and dynamic conception of the object. Focillon’s and Schapiro’s models may help to pave the way for an art theory that combines production and reception aesthetics, in understanding art as a never accomplished process of negotiation between the poles of artistic activity, material properties, society and the viewer.

Full textAbstract:
In ‘Polish psych nominals revisited’ Rozwadowska provides supports for the n-based approach to nominalizations (developed in numerous papers by Alexiadou and Borer, among others) by providing the evidence from a variety of Polish psych nominals for varying sizes of the verbal structure embedded in them. So far, it has been widely recognized in cross-linguistic literature that psych nominals denote states (see Grimshaw, 1990; Pesetsky, 1995; Alexiadou, 2011a; Fábregas & Marín, 2012; Melloni, 2017; Iordăchioaia, 2019a, inter alia). Rozwadowska argues that in addition to stative psych nominals, which themselves have a verbal layer embedded in them, Polish systematically has eventive reflexive psych nominalizations with a rich verbal structure that describe the inceptive events, i.e. boundary events which denote the beginning of the state. To show that, she focuses on the nominals derived from alternating Experiencer Object/Experiencer Subject reflexive verbs. Additionally, Rozwadowska argues that eventive inceptive psych nominals derived from Experiencer Object verbs, with a rich verbal structure embedded in them, are not causative. Thus, this chapter constitutes a contribution to the debate on the presence/absence of the component of causation in Experiencer Object verbs and their nominalizations.<186>

In particular, intellectual property and government secrets are now identified most often as the primary object of cyber threats. When critical infrastructure is mentioned, it is often used as a motivational tactic, with collapse of critical infrastructure serving as a central theme of hypothetical scenarios meant to motivate a policy response.

Full textAbstract:
This chapter investigates the significance of legal theory for understanding the role of law in the European Union. It does so by comparing and evaluating which theoretical approach, or approaches, generates the best conception of the role of law in articulating a vision of the world’s first supranational polity. The key candidate conceptions are supplied by positivism, idealism, culturalism, and pragmatism. For the positivist, the focus is on ‘the authorised law’; for the idealist, ‘the good law’; for the culturalist, ‘the appropriate law’; and for the pragmatist, ‘the law that works’. Whereas EU law lacks the direct democratic resources, the plausible claim to universalism, and the sense of common cultural identity to support robust versions of positivism, idealism, and culturalism respectively, its investment in the security and versatility of law in providing positive-sum policy outputs has supported instead a primarily pragmatic vison of law’s legitimacy. The chapter concludes by examining the fragility of excessive dependence on the pragmatic model of law in a political environment where the various crises of the European Union increasingly undermine even modest levels of secondary reliance on positivist, idealist, and culturalist justifications.

Full textAbstract:
Data management in mobile computing has emerged as a major research area, and it has found many applications. This research has produced interesting results in areas such as data dissemination over limited bandwidth channels, location-dependent querying of data, and advanced interfaces for mobile computers (Barbara, 1999). However, handling multimedia objects in mobile environments faces numerous challenges. Traditional methods developed for transaction processing (Silberschatz, Korth & Sudarshan, 2001) such as concurrency control and recovery mechanisms may no longer work correctly in mobile environments. To illustrate the important aspects that need to be considered and provide a solution for these important yet “tricky” issues in this article, we focus on an important topic of data management in mobile computing, which is concerned with how to ensure serializability for mobile-client data caching. New solutions are needed in dealing with caching multimedia data for mobile clients, for example, a cooperative cache architecture was proposed in Lau, Kumar, and Vankatesh (2002). The particular aspect considered in this article is that when managing a large number of multimedia objects within mobile client-server computing environments, there may be multiple physical copies of the same data object in client caches with the server as the primary owner of all data objects. Invalid-access prevention policy protocols developed in traditional DBMS environment will not work correctly in the new environment, thus, have to be extended to ensure that the serializability involving data updates is achieved in mobile environments. The research by Parker and Chen (2004) performed the analysis, proposed three extended protocols, and conducted experimental studies under the invalid-access prevention policy in mobile environments to meet the serializability requirement in a mobile client/server environment that deals with multimedia objects. These three protocols, referred to as extended server-based two-phase locking (ES2PL), extended call back locking (ECBL), and extended optimistic two-phase locking (EO2PL) protocols, have included additional attributes to ensure multimedia object serializability in mobile client/server computing environments. In this article, we examine this issue, present key ideas behind the solution, and discuss related issues in a broader context.

This paper presents a principled way for dealing with occlusions in visual tracking which is a long-standing issue in computer vision but largely remains unsolved. As the major innovation, we develop a learning-based jump-diffusion process to jointly track object locations and estimate their visibility statuses over time. Our method employs in particular a set of jump dynamics to change object's visibility statuses and a set of diffusion dynamics to track objects in videos. Different from the traditional jump-diffusion process that stochastically generates dynamics, we utilize deep policy functions to determine the best dynamic at the present step and learn the optimal policies from raw videos using reinforcement learning methods.Our method is capable of tracking objects with severe occlusions in crowded scenes and thus recovers the complete trajectories of objects that undergo multiple interactions with others. We evaluate the proposed method on challenging video sequences and compare it to alternative methods. Significant improvements are obtained particularly for the videos including frequent interactions or occlusions.

Full textAbstract:
An interoperability gap exists between Learning Management Systems (LMS) and Learning Ob ject Repositories (LOR). LORs are responsible for the storage and management of Learning Objects and the associated Learning Object Metadata (LOM). LOR(s) adhere to various LOM standards depending up the requirements established by user groups and LOR administrators. Two common LOM standards found in LORs are CanCore (Canadian LOM standard) and the Sharable Content Object Reference Model (SCORM) Content Aggregation Model (CAM). In contrast, LMSs are independent computer systems that manage and deliver course content to students via a web interface. This research addresses three important issues related to this problem domain: (a) a lack of metadata standards that define the format of how assessment data should be communicated from Learning Management Systems to Learning Object Repositories, (b) a lack of Information Engineering (IE) architectural standards for the transfer of data from Learning Management Systems to Learning Object Repositories, and (c) a lack of middleware that facilitates the movement of the assessment data from the Learning Management Systems to Learning Object Repositories. Thus, the three goals of this research are: (a) make recommendations for extending the CanCore and SCORM CAM LOM standards to facilitate the storage of assessment and summary assessment data, (b) define the foundation for an IE architectural standard based on an Access Control Policy (ACP) and Data Validation Policy (DVP) using a reliable consensus of experts with the Delphi technique, and (c) develop a middleware prototype that transfers learning assessment data from multiple Learning Management Systems into the Learning Object Metadata of Learning Objects that are stored within a CanCore or SCORM compliant Learning Object Repository.

Full textAbstract:
Intelligent robots frequently need to explore the objects in their working environments. Modern sensors have enabled robots to learn object properties via perception of multiple modalities. However, object exploration in the real world poses a challenging trade-off between information gains and exploration action costs. Mixed observability Markov decision process (MOMDP) is a framework for planning under uncertainty, while accounting for both fully and partially observable components of the state. Robot perception frequently has to face such mixed observability. This work enables a robot equipped with an arm to dynamically construct query-oriented MOMDPs for multi-modal predicate identification (MPI) of objects. The robot's behavioral policy is learned from two datasets collected using real robots. Our approach enables a robot to explore object properties in a way that is significantly faster while improving accuracies in comparison to existing methods that rely on hand-coded exploration strategies.

Full textAbstract:
Many Polish cities have objects in them that have ceased to function in accordance with their intended use, for one reason or another. These are often post-industrial objects and former military facilities. As a result of the social, political and economic transformations that have taken place in Poland over the years after the Second World War, these objects have lost the meaning of their existence and functioning. Quite often such objects also have a historical character, which may, under Polish law, serve to hinder the possibility of them being reused. A well prepared revitalisation is often the only way for such objects to regain their earlier functionality, or gain a new one. Selected examples of the revitalisation of historic buildings located in Olsztyn (the capital of Warmia and Mazury, the Voivodeship in North-East Poland) were analysed by the authors in this article, and the effects of such actions, connected to the development of the city, were presented. The study included examples of the revitalisation of post-industrial objects and former military facilities. The analysis was performed in the years 2010–2016. The history and previous functional status of the tested objects were presented, as well as their present form and function. The authors have performed a comprehensive analysis of the compliance of new functions of objects with the idea of the sustainable development of the city. The results show the extent to which the analysed activities comply with the principles of sustainable development, in social, economic and environmental terms.

Full textAbstract:
While some debate has existed in the literature regarding the relationship between roof crush and occupant injury, the United States (U.S.) National Highway Traffic Safety Administration (NHTSA) has identified an increased safety benefit in improving roof strength and has mandated new higher roof crush resistance requirements. Frequently, roof impacts occur in rollover crashes when a vehicle travels off the lanes of the roadway and impacts various types of narrow objects along the roadway edge such as light poles, utility poles and/or trees. A previously reported tilt-test device and methodology is presented along with a new pendulum-test device and methodology, both of which allow for dynamic, repeatable impact evaluation of vehicle roof structures with narrow objects. The data collected includes not only residual crush, but also dynamic vehicle instrumentation and high speed video analysis. Two series of full vehicle tests are reported which represent each of the methodologies. The testing conditions for each series was determined based upon analysis of a real-world narrow object rollover impact. Each testing series allows for analysis of the damage resulting from the narrow object impact to the roof structure for a production vehicle as well as one that has been structurally reinforced. Results demonstrate that the reinforced roof structure significantly reduced the roof deformation compared to that of the production roof structure. The input energy of each test and resulting damage patterns can be used as both a reconstruction tool and structural assessment test.

Full textAbstract:
In Poland land consolidation is carried out mainly in the southern part of the country. In three voivodships, Lublin Voivodship, Podkarpackie Voivodship and Lesser Poland Voivodship, in the years 2003–2014 there were numerous land consolidations, over 20,000 ha in each voivodship. That is above national average of land consolidation. In another three voivodships (Warmian-Masurian Voivodship, West Pomeranian Voivodship and The Kuyavian-Pomeranian Voivodship) there are no land consolidation, even though according to scientists from the Polish, every voivodship requires land consolidations processes. What is the reason for that situation? Why are so many land consolidations conducted in the area of several voivodships in Poland, and in other voivodships considerably less or not at all? It is known that the location of the implementation of agricultural land consolidations in a particular area is determined by numerous factors, inter alia the construction of line infrastructural projects i.e. motorways, faulty spatial structure found in a particular area, and farmers in Poland applying for the implementation of this project. It is also known that the neighbourhood of the implementation of these works is of significance. Situations are observed in which the appearance of one consolidation object contributes to the development of this measure in the neighbouring area. However, there is no empirical evidence to support this view. Therefore, the subject of considerations will be the investigation into the occurrence of spatial relationships between consolidation objects. Two variables were adopted for the analysis, namely the number and density of consolidations. In order to determine the relationships, spatial autocorrelation was applied.

Full textAbstract:
Abstract For the past few years, training robots to enable them to learn various manipulative skills using deep reinforcement learning (DRL) has arisen wide attention. However, large search space, low sample quality, and difficulties in network convergence pose great challenges to robot training. This paper deals with assembly-oriented robot grasping training and proposes a DRL algorithm with a new mechanism, namely, policy guidance mechanism (PGM). PGM can effectively transform useless or low-quality samples to useful or high-quality ones. Based on the improved Deep Q Network algorithm, an end-to-end policy model that takes images as input and outputs actions is established. Through continuous interactions with the environment, robots are able to learn how to optimally grasp objects according to the location of maximum Q value. A number of experiments for different scenarios using simulations and physical robots are conducted. Results indicate that the proposed DRL algorithm with PGM is effective in increasing the success rate of robot grasping, and moreover, is robust to changes of environment and objects.

Full textAbstract:
One of the forms of care for the elderly are the nursing homes, long-term care homes. Still, in many countries the low level of quality of such services is still the main criterion for the perception of objects as a final option, in the absence of alternative forms of care for an older person. The aim of the article is to seek answers to the questions about the expected quality of the services offered by nursing homes. The article presents the results of research on the expectations of the society in terms of quality of services, carried out on a sample of 602 Polish citizens.

Full textAbstract:
Conformal (or freeform) and steep concave optics are important classes of optics that are difficult to finish using conventional techniques due to mechanical interferences and steep local slopes. One suitable way to polish these classes of optics is by using a jet of abrasive/fluid mixture. In doing so, the energy required for polishing may be supplied by the radial spread of a liquid jet, which impinges a surface to be polished. Such fluid flow may generate sufficient surface shear stress to provide material removal in the regime of chemical mechanical polishing. Once translated into a polishing technique, this unique tool may resolve a challenging problem of finishing steep concave surfaces and cavities. A fundamental property of a fluid jet is that it begins to lose its coherence as the jet exits a nozzle. This is due to a combination of abruptly imposed longitudinal and lateral pressure gradients, surface tension forces, and aerodynamic disturbance. This results in instability of the flow over the impact zone and consequently polishing spot instability. To be utilized in deterministic high precision finishing of remote objects, a stable, relatively high-speed, low viscosity fluid jet, which remains collimated and coherent before it impinges the surface to be polished, is required. A method of jet stabilization has been proposed, developed and demonstrated whereby the round jet of magnetorheological fluid is magnetized by an axial magnetic field when it flows out of the nozzle. It has been experimentally shown that a magnetically stabilized round jet of MR polishing fluid generates a reproducible material removal function (polishing spot) at a distance of several tens of centimeters from the nozzle. In doing so, the interferometrically derived distribution of material removal for an axisymmetric MR Jet, which impinges normal to a plane glass surface, coincides well with the radial distribution of rate of work calculated using computational fluid dynamics (CFD) modeling. Polishing results support the assertion that the MR Jet finishing process may produce high precision surfaces on glasses and single crystals. The technology is most attractive for the finishing of complex shapes like freeform optics, steep concaves and cavities.

Binary determination of the presence of objects is one of the problems where humans perform extraordinarily better than computer vision systems, in terms of both speed and preciseness. One of the possible reasons is that humans can skip most of the clutter and attend only on salient regions. Recurrent attention models (RAM) are the first computational models to imitate the way humans process images via the REINFORCE algorithm. Despite that RAM is originally designed for image recognition, we extend it and present recurrent existence determination, an attention-based mechanism to solve the existence determination. Our algorithm employs a novel $k$-maximum aggregation layer and a new reward mechanism to address the issue of delayed rewards, which would have caused the instability of the training process. The experimental analysis demonstrates significant efficiency and accuracy improvement over existing approaches, on both synthetic and real-world datasets.
