We developed a method to generate omnidirectional depth maps from corresponding omnidirectional images of cityscapes by learning each pair of an omnidirectional and a depth map, created by computer graphics, using pix2pix. Models trained with different series of images, shot under different site and sky conditions, were applied to street view images to generate depth maps. The validity of the generated depth maps was then evaluated quantitatively and visually. In addition, we conducted experiments to evaluate Google Street View images using multiple participants. We constructed a model that predicts the preference label of these images with and without the generated depth maps using the classification method with deep convolutional neural networks for general rectangular images and omnidirectional images. The results demonstrate the extent to which the generalization performance of the cityscape preference prediction model changes depending on the type of convolutional models and the presence or absence of generated depth maps.
Sentiment analysis is directly affected by compositional phenomena in language that act on the prior polarity of the words and phrases found in the text. Negation is the most prevalent of these phenomena, and in order to correctly predict sentiment, a classifier must be able to identify negation and disentangle the effect that its scope has on the final polarity of a text. This paper proposes a multi-task approach to explicitly incorporate information about negation in sentiment analysis, which we show outperforms learning negation implicitly in an end-to-end manner. We describe our approach, a cascading and hierarchical neural architecture with selective sharing of Long Short-term Memory layers, and show that explicitly training the model with negation as an auxiliary task helps improve the main task of sentiment analysis. The effect is demonstrated across several different standard English-language data sets for both tasks, and we analyze several aspects of our system related to its performance, varying types and amounts of input data and different multi-task setups.
The relationship between zoo animals, particularly nonhuman primates, and visitors is complex and varies by species. Adding complexity to this relationship is the trend for zoos to host events outside of normal operating hours. Here, we explored whether a late-night haunted-house style event influenced the behavior of spider monkeys. We conducted behavioral observations both on event nights and nights without the event. The spider monkeys were active and outside more frequently on event nights compared to the control nights indicating that their typical nighttime behavior was altered. However, it is difficult to definitively conclude whether the behavioral changes were a result of the event being aversive or enriching. Our findings suggest that zoos should conduct behavioral observations of and collect physiological data from their animals, especially if they are sensitive to environmental changes, when implementing new events, including those occurring outside of normal operating hours to ensure high levels of animal welfare.
This study deals with widespread issues on constituent parsing for Korean including the quantitative and qualitative error analyses on parsing results. The previous treebank grammars have been accepted as being interpretable in the various annotation schemes, whereas the recent parsers turn out to be much harder for humans to interpret. This paper, therefore, intends to find the concrete typology of parsing errors, to describe how these parsers deal with sentences and to show their statistical distribution, using state-of-the-art statistical and neural parsers. For doing this work, we train and evaluate the phrase structure Sejong treebank using statistical and neural parsing systems and obtain results up to a 89.18% F$_1$ score, which outperforms previous constituent parsing results for Korean. We also define best practices for correct comparison to future work by proposing the standard corpus division for the Sejong treebank.
The Erdős–Simonovits stability theorem states that for all ε > 0 there exists α > 0 such that if G is a Kr+1-free graph on n vertices with e(G) > ex(n, Kr+1)– α n2, then one can remove εn2 edges from G to obtain an r-partite graph. Füredi gave a short proof that one can choose α = ε. We give a bound for the relationship of α and ε which is asymptotically sharp as ε → 0.
Driven by their affinity to popular culture, fans frequently engage in linguistic practices that may be conducive to language learning. This study seeks to find out how a group of Catalan-speaking gamers decided to start producing fan translations of video games from English into Catalan. Based on a digital ethnography (online interviews and observation of the group’s activity), two types of analysis were conducted: a content analysis for recurrent trends and a focused analysis of internal metalinguistic discussions on the quality of translations. Results indicate that fan translators (1) organize hierarchically with set roles and functions, (2) curate their group identity and care for the promotion of Catalan as a vehicle for cultural production, (3) learn language incidentally in three ways: while translating (ensuring the comprehension of English and the linguistic quality and creativity of the transfer into Catalan), through sharing language doubts with their peers on their Telegram group and dialogically agreeing on pragmatically acceptable English-Catalan translations, and through metalinguistic discussions on translation tests received from potential new members. The study resonates with a novel subfield in computer-assisted language learning: language learning in the digital wilds, which might be fertile ground for studies on incidental and informal language learning online. The study may also serve as inspiration for effective integration of translation into language classrooms in a manner that bridges vernacular fan translation and pedagogic translation, considering the importance of metalinguistic discussion for language learning and the sociocultural dimension of both translation and language learning.
The purpose of this chapter is to explore the impact of the Global Financial Crisis (GFC) and austerity on collective bargaining and wage outcomes internationally. It takes as the starting point for its analysis the argument advanced in Chapter 1 that the current wave of austerity policies stems from a neoliberal economic consensus that has pervaded developed economies and emphasizes free markets, the removal of rigidities to capital and shrinking the state. That is a philosophy that in policy terms is the antithesis of one supportive of trade unions and collective bargaining, which are themselves under this ideology seen as impediments to markets and economic growth (Harvey, 2007). The chapter therefore adopts a perspective that sees the GFC and austerity as providing a convenient point from which to further consolidate neoliberalism's hold on society (McCann, 2013) and simultaneously undermine one of the chief forms of resistance – trade unions and collective bargaining.
The first part of the chapter focuses attention on exploring trends in collective bargaining in the EU and North America (US and Canada) in the post-GFC period. In doing so, it identifies a common trajectory in nation-state policies that encompasses a shift towards identifying the GFC as a public debt crisis; the blaming of trade unions and their members (in particular public sector workers) for the crisis; and the introduction of reforms to collective bargaining and union security designed to reinforce deflationary austerity policies. The chapter's second part then examines trends in wage growth and equality since 2008 and discusses the factors influencing them and the extent to which they can be viewed as a product of the neoliberal-informed economic policies and reforms adopted in response to the crisis.
Changes to collective bargaining in the EU
Institutional context of collective bargaining in the EU under austerity
Since 2000 there have been significant social, economic and political policy shifts that have fundamentally challenged the status of collective bargaining in the EU. Policies associated with a neoliberal agenda that view unions and collective bargaining as sources of rigidities in the market have been central to this change as the EU has focused on the neoliberal free market agenda of labour-market flexibility and downward pressure on terms and conditions to sustain economic growth (Waddington, Muller and Vandaele, 2019). This process of change received support from EU enlargement and the move towards economic and monetary union (EMU).
This chapter examines restructuring in the public services as a policy response to fiscal consolidation pressures. More specifically, it describes restructuring efforts aimed at rationalization and efficiency gains at several levels, including national, organizational, workgroup and job. The case study of Fire and Rescue Services in Scotland illustrates the manifestations of work restructuring at different levels of analysis, and potential consequences for individual experiences of work.
As detailed in Chapter 1, the transformation of the global financial crisis (GFC) into a sovereign debt crisis put public budgets under strain and public expenditure in the spotlight in a significant share of Organisation for Economic Co-operation and Development (OECD) nations. Contraction of public expenditure through cuts and restructuring of public services formed part of the main policy response. Considering the labour-intensive nature of service provision, savings in public sector workforce compensation formed one of the main foci (Glassner and Watt, 2010; Grimshaw et al, 2012), either through reductions in workforce size or through direct decreases in remuneration and benefits (OECD, 2012, p 23).
The combined pressures of identifying parts of the public services that could be (further) cut in a context of increased demand for public services in times of recession, such as for social security and education, arguably further fuelled fiscal retrenchment measures that sought efficiency gains under the banner of ‘more with less’ (Vaughan-Whitehead, 2013, pp 8, 36; Eurofound, 2015, pp 5–6, 60). As the OECD (2011a, p 9) put it: ‘To avoid an excessive curtailing of public services, the state needs to be streamlined and made more efficient.’ Consequently, various rationalization efforts involving a restructuring of public services from national level down to the job or workgroup level could be observed as policy responses across Europe. Efficiency gains and cost reductions were key drivers of such restructuring measures.
The focus of this chapter is restructuring as a means of addressing the ‘labour problem’ of how to enhance efficiency in the public sector (Worrall et al, 2010). It begins by identifying multiple levels where restructuring has occurred, and an analytical framework for the case of the Scottish Fire and Rescue Service.
A decade after the ‘global’ financial crisis, austerity is still being debated in relation both to post-crisis policy orientations and to longer-term trends since the 1970s (Dunn, 2014; McBride and Baines, 2014; Whiteside, 2018a). It is clear from the significant body of scholarship focusing on Western ‘worlds of welfare capitalism’ (Esping-Andersen, 1990) that austerity – in the sense of policies that constrain or reduce public spending on social welfare; (re)privatize or (re)commodify welfare state functions, public goods and public assets (including infrastructure) and seek to shrink the ‘social state’ (Peck, 2013) – is connected both to state responses to the 2008 financial crisis and to longer-run processes and mechanisms. These include capitalist restructuring associated with neoliberalization and with the rise of New Public Management (NPM) as a vehicle for redrawing the boundaries between state and market. NPM refers to an ideology and policy framework for the management of public finances and the public sector that seeks to embed a managerialist model ‘characterized by competitive tendering, strict adherence to legalistic contracts and performance indicators, private-sector business practices, short-term funding and continued calls for efficiency, “more for less”, value for money and cost savings’ (Cunningham et al, 2017, pp 370–1).
As we argue in this chapter, however, context-specific and relational understandings of austerity and the complex policy mobilities (McCann and Ward, 2012) of NPM require critical attention to how processes play out in particular contexts (Pike et al, 2018). There are common trends, but unevenness also exists at the national and sub-national levels (Baines and Cunningham, 2015). Moreover, the policy diffusion of NPM also goes beyond European and Anglo-American welfare states and – as in countries like Canada and Australia that did not suffer financial crises – has been a convenient driver of reform. This chapter contributes to the literatures on austerity and NPM by comparing two such contexts, focusing on sub-national scales to examine the social care sector in Vancouver, British Columbia (Canada) and Shanghai (China). It does so by using the concept of social infrastructure to connect state-led marketization and outsourcing in the eldercare sector with, on the one hand, the influence of NPM and, on the other, the financialization that has accelerated in the past two decades.
Clarke (2017, p 23) argues that, rather than a wholly new project, austerity is ‘assembled anew in specific times and places, but in ways that draw on or at least try to mobilize – older stocks of knowledge and sentiment’. Privatization is one of these older stocks of knowledge and sentiment that have yet to be wholly actualized in most developed countries (Starr, 1987). Clarke (2017, p 26) argues further that it is helpful to think about the present as ‘the accumulation of failure: failed, stalled, or incomplete hegemonic projects that try to combine economic, social, and political restructuring with the securing of popular consent to that project’. Privatization can be viewed as an incomplete hegemonic project, and a central aspect of neoliberalism that austerity has revisited with enthusiasm, once again trying to win popular consent to reduce and remove public entitlements and services. Although little evidence has been produced to back the claim, neoliberals have long argued that privatization provides cost savings, efficiency and greater accountability through increased competition and consumer choice (Yarrow, 1986; Kamerman and Kahn, 2014). These arguments have resurfaced boldly in the post-2008 global financial crisis (GFC) and current iteration of austerity.
Although privatization is often thought of as a singular phenomenon, this chapter will identify seven forms of overlapping and interwoven privatization. In the current era of austerity, privatization has been able to extend its reach through these integrated processes and, in some cases, operate almost by stealth as an overarching ideological force that legitimizes private market relations in places where it once would have been thought to be contrary to a public sector ethic of entitlement and equity. This is a growing dynamic across many public and non-profit/voluntary services and organizations. Services and assets are privatized in their entirety, as well as piece by piece through the contracting out of various aspects of the organization such as human resources management, cleaning, security, management itself, specialists, consultants and the use of temporary workers hired through for-profit agencies. As Armstrong et al (1997) argued earlier in the era of neoliberalism, among political economists, private and public are increasingly not viewed as ‘dichotomous, readily separable entities.
