Macau’s Heterotopias: Ruins of St. Paul’s as a Spatial and Temporal Disruption

This article explores and decodes the social experiences of the ruins of St. Paul’s in Macau. The depictions of St. Paul’s as a disruptive social space are elucidated by the concepts of heterotopia, palimpsest and liminality. As a palimpsest, Macau’s ruins comprise a variety of concealed and superimposed semantic layers. One can read the ruins and decipher these semantic tiers. The reading of buildings as palimpsests recognises the paradoxical combination of their durable and transitory nature. St. Paul’s ruins encompass several stratified discourses such as cultural, historical, aesthetic. All of them are deciphered in their multivalent configurations, revealing their overarching heterotopic quality. This article aims to display St. Paul’s ruins as a culturally meaningful urban space of otherness within the ambivalent spatial realm of Macau while unfolding its disruptive nature.     

A Primer on Visualizations for Comparing Populations,Including the Issue of Overlapping Confidence Intervals

In comparing a collection of K populations, it is common practice to display in one visualization confidence intervals for the corresponding population parameters θ₁, θ₂, …, θ_K. For a pair of confidence intervals that do (or do not) overlap, viewers of the visualization are cognitively compelled to declare that there is not (or there is) a statistically significant difference between the two corresponding population parameters. It is generally well known that the method of examining overlap of pairs of confidence intervals should not be used for formal hypothesis testing. However, use of a single visualization with overlapping and nonoverlapping confidence intervals leads many to draw such conclusions, despite the best efforts of statisticians toward preventing users from reaching such conclusions. In this article, we summarize some alternative visualizations from the literature that can be used to properly test equality between a pair of population parameters. We recommend that these visualizations be used with caution to avoid incorrect statistical inference. The methods presented require only that we have K sample estimates and their associated standard errors. We also assume that the sample estimators are independent, unbiased, and normally distributed.

Effects of human-related disturbance on breeding success of urban and non-urban blue tits (<Emphasis Type=Italic>Cyanistes caeruleus</Emphasis>)

There is a need to study the effects of urbanization on wildlife in order to understand the ecological implications of increasing urbanization and find out how to reduce its threats to biodiversity. The blue tit evolved as a forest species and prefers deciduous and mixed forests, whereas its nesting in urban habitats is a more recent phenomenon. Our long-term study of blue tit populations has been conducted in two habitats: an urban parkland (frequently visited by people) and a deciduous forest outside of the city. Using linear mixed modeling, we revealed that a relationship of blue tit breeding success (and the number of fledglings) with thermal conditions in May differed between the urban parkland and the forest. While the relationship was positive in the forest, it was negative in the parkland. In addition, breeding success in the parkland increased with increasing number of rainy days in May. We argue that the main possible reason for such patterns is human activity in the parkland, which interferes with tit parental care, especially the regular feeding of nestlings, whereas it is evidently associated with weather conditions. Human disturbance in the forest is likely to be negligible.     

Gambling participation in the U.S.--results from a national survey

Demographic patterns of gambling participation in the U.S. were examined. A national telephone survey was conducted with 2,630 representative U.S. residents aged 18 or older. The sample as weighted for analysis was 48% male, 12% black, and 11% Hispanic. Respondents were questioned on 15 types of gambling: how often they played and how much they won or lost. Eighty-two percent gambled in the past year. Lottery was the most commonly played game, while casino gambling accounted for the largest extent of gambling involvement. Men and women were equally likely to gamble in the past year, but men gambled more frequently and had larger wins and losses, particularly on sports betting and games of skill. Blacks were less likely to have gambled in the past year, but blacks who gambled did so more heavily than other racial groups. Blacks and Hispanics were more likely than average to be pathological gamblers. The rate of past year gambling declined with age, but extent of gambling involvement among gamblers did not vary with age. Rates of participation in most forms of gambling increased with socioeconomic status, but higher socioeconomic status gamblers had lower rates of pathological gambling, and lower extent of gambling involvement, particularly for lottery. New Englanders gambled more heavily than other Americans. Comparison with past studies showed an increase in overall gambling participation in the U.S., and large increases in rates of participation in lottery and casino gambling.     

Application of the Rural Development Index to Analysis of Rural Regions in Poland and Slovakia

The main purpose of this research was to construct a multi-dimensional (composite) index measuring the overall level of rural development and quality of life in individual rural regions of a given EU country. In the Rural Development Index (RDI) the rural development domains are represented by hundreds of partial socio-economic, environmental, infrastructural and administrative indicators/variables at NUTS-4 level (e.g. 991 variables/indicators describing various aspects of rural development in Poland; 340 variables/indicators in Slovakia). The weights of economic, social and environmental domains entering the RDI index are derived empirically from the econometrically estimated intra- and inter-regional migration function after selecting the “best” model from various alternative model specifications (e.g. panel estimate logistic regression nested error structure model, spatial effect models, etc.). The RDI is empirically applied to analysis of the main determinants of rural/regional development in individual rural areas in years 2002–2005 in Poland and Slovakia at NUTS-4 level. Due to its comprehensiveness the RDI Index is suitable both to analysis of the overall level of development of rural areas and to an evaluation of the impacts (impact indicator) of RD and structural programmes at regional levels (NUTS 2–5).     

Victimization, Psychological Distress and Subsequent Offending Among Youth

The current study examined the relationship between the victimization of youth, psychological distress and subsequent offending. It examined whether direct and vicarious victimization by exposure to violence in the family, among peers, and in the neighborhood, significantly predicted psychological distress among study participants and whether psychological distress significantly predicted subsequent offending over time. In addition, it examined the extent (if any) to which psychological distress mediated the relationship between victimization and subsequent offending. Method: study data are from wave 1 and wave 2 of the Buffalo Longitudinal Study of Young Men (BLSYM), a population based sample (n = 625) of young men, ages 16-19 years old in a metropolitan area of Buffalo, New York. A path analytic approach was used for the main analyses. Findings: personal, vicarious victimization by exposure to violence among peers, and perception of neighborhood safety were significant predictors of offending at wave 1. Personal and property victimization was significant predictors of psychological distress. Psychological distress did not have a significant relationship with offending at wave 1 yet, it did at wave 2. Vicarious victimization by exposure to violence among peers and offending at wave 1 were all significant predictors of offending at wave 2. The results highlight the need to respond to both direct and vicarious victimization among young males to reduce psychological distress and subsequent offending.     

The Relationship Between Distance from Gambling Venues and Gambling Participation and Problem Gambling Among U.S. Adults

In this article we examine the relationship between extent of gambling for U.S. adults and the distance from their residence to the nearest casino or track. We employ data from a telephone survey of U.S. adults conducted in 2011–2013. The chances that the respondents gambled in the past year, were frequent gamblers, or were problem gamblers were greater if they lived close to a casino. The chances that the respondents gambled in the past year or were frequent gamblers were greater if they lived close to a horse or dog track. The effects of closeness to a casino on the likelihood of past-year gambling, frequent gambling, and problem gambling, as well as the effect of closeness to a track on past-year gambling, extended to about 30 miles from the respondent’s home. In addition, the concentration of casinos within 30 miles of the respondent’s home was positively related to the respondents’ chance of being a frequent or problem gambler. If a respondent had no casinos within 30 miles, he or she had a 2.7 % chance of being a problem gambler; if one casino, a 3.9 % chance; if six or more, a 6.2 % chance. The authors estimate that at least part of this effect is causal.
