Large-Scale Analysis of Zipf’s Law in English Texts

Despite being a paradigm of quantitative linguistics, Zipf’s law for words suffers from three main problems: its formulation is ambiguous, its validity has not been tested rigorously from a statistical point of view, and it has not been confronted to a representatively large number of texts. So, we can summarize the current support of Zipf’s law in texts as anecdotic. We try to solve these issues by studying three different versions of Zipf’s law and fitting them to all available English texts in the Project Gutenberg database (consisting of more than 30 000 texts). To do so we use state-of-the art tools in fitting and goodness-of-fit tests, carefully tailored to the peculiarities of text statistics. Remarkably, one of the three versions of Zipf’s law, consisting of a pure power-law form in the complementary cumulative distribution function of word frequencies, is able to fit more than 40% of the texts in the database (at the 0.05 significance level), for the whole domain of frequencies (from 1 to the maximum value), and with only one free parameter (the exponent).

Do you see what I'm saying? Interactions between auditory and visual cortices in cochlear implant users

Primary sensory cortices are generally thought to be devoted to one sensory modality-vision, hearing, or touch, for example. Surprising interactions between these sensory modes have recently been reported. One example demonstrates that people with cochlear implants show increased activity in visual cortex when listening to speech; this may be related to enhanced lipreading ability.     

Going native? Flower use by bumblebees in English urban gardens

Background and Aims

Although urban gardens provide opportunities for pollinators in an otherwise inhospitable environment, most garden plants are not native to the recipient biogeographical region and their value to local pollinators is disputed. This study tested the hypothesis that bumblebees foraging in English urban gardens preferentially visited sympatric Palaearctic-range plants over species originating outside their native range.

Methods

Twenty-seven surveys of flower availability and bumblebee visitation (Bombus spp.) were conducted over a 3-month summer period. Plants were categorized according to whether they were native British, Palaearctic or non-Palaearctic in origin. A phylogeny of the 119 plant species recorded was constructed and the relationship between floral abundance and the frequency of pollinator visits investigated by means of phylogenetically independent contrasts. Differentiation in utilization of plant species by the five bumblebee species encountered was investigated using niche overlap analyses.

Key Results

There was conflicting evidence for preferential use of native-range Palaearctic plant species by bumblebees depending on which plants were included in the analysis. Evidence was also found for niche partitioning between species based on respective preferences for native and non-native biogeographical range plants. Two bumblebees (Bombus terrestris and B. pratorum) concentrated their foraging activity on non-Palaearctic plants, while two others (B. hortorum and B. pascourum) preferred Palaearctic species.

Conclusions

The long-running debate about the value of native and non-native garden plants to pollinators probably stems from a failure to properly consider biogeographical overlap between plant and pollinator ranges. Gardeners can encourage pollinators without consideration of plant origin or bias towards ‘local’ biogeographical species. However, dietary specialist bumblebees seem to prefer plants sympatric with their own biogeographical range and, in addition to the cultivation of these species in gardens, provision of native non-horticultural (‘weed’) species may also be important for pollinator conservation.     

‘I'm American,not Japanese!’: the struggle for racial citizenship among later-generation Japanese Americans

Abstract

As one of the oldest Asian American groups in the USA, most Japanese Americans are of the third and fourth generations and have become well integrated in mainstream American society. However, they are still racialized as foreigners simply because of their Asian appearance. Their Asian phenotype continues to have a foreigner connotation because of large-scale immigration from Asia and an American national identity that is racially defined as white. This paper analyses how later-generation Japanese Americans are racialized as outsiders in their daily interaction with mainstream Americans, which is often accompanied by essentialized assumptions that they are also culturally foreign. In response, they engage in everyday struggles for racial citizenship by demanding inclusion in the national community as Americans despite their racial differences. It is uncertain whether such attempts to contest their racialization will cause current mono-racial notions of American identity to be reconsidered in more inclusive and multiracial ways.     

‘I'm black and I'll always be that way’: black identities through the lens of interracial intimacy

Early research on black racial identity development cautioned that close relationships with whites signalled an alienation from blackness and a subconscious acceptance that ‘white is right’. These assumptions mirrored popular media and political discourse suggesting that romantic relationships outside of one's racial group reflect a devalued or inauthentic racial self. More recent scholarly research presents a mixed picture about the role of interracial intimacy on black racial identities. Using in-depth qualitative narratives with forty-two interracially partnered African Americans, this article explores whether interracial intimacy recasts the meaning or intensity of black racial identities. Findings affirm that black racial identities are heterogeneous – some partners experienced blackness as a central, fundamental identity while others possessed ambivalent attachments to blackness. Across these experiences, however, adult interracial intimacy had at most an incremental influence on racial identity. Interracial contact during adolescence was far more influential because it allowed blacks to develop dimensions of white cultural identity.     

MP offers a testimonial: “I've had superb care,and I'm alive today because of it”

When Beryl Gaffney, a Liberal member of Parliament, was told she had a brain tumour, she decided to take control of her own life. Instead of allowing the first doctor she saw to rush her to hospital, she travelled to Montreal and London, Ont., to get a second and third opinion. Then she showed neurologists in Atlanta her test results and asked which of the three options for treatment she had received coincided with their treatment recommendation. Today, she is back in the House of Commons, where she spends much of her time debating health care issues.     

‘You may not know it,but I'm black’: White women's self‐identification as black*

This article shows ways in which five European American women intertwine and interweave the American discourses of race and ethnicity to talk about themselves as ‘black.’ This black identity both fits with their anti‐racist desires and makes strategic sense in the context of their everyday lives. Importantly, the women do not deny the European side of their heritage, rather they embrace a multi‐racial/ethnic identity. It is argued that the element of choice involved with American ethnic discourse, combined with a general shift toward the allowance of mixed identities, allows this identity construction to be understood as a sensible one. It is further argued that these women's constructions illustrate a type of identity configuration that has become a highly significant option in the United States.     

Palaeolimnology in the English Lakes — some questions and answers over fifty years

In a review of work on 10 of the very numerous lakes of the English Lake District — work which involved co-operation between palaeolimnologists from different disciplines and between palaeo- and neolimnologists — the questions asked by the researchers are listed and it is shown which kind of lake has provided constructive answers. Complete and conformable sediment profiles covering the last ca 14 000 years are found in these lakes, but no single profile is optimal for study of the whole period. Knowledge of the pattern of sediment accumulation is necessary before the record in microfossils and changing sediment composition can be interpreted with confidence. The demonstration that the sediment-source material of these open lakes must have been largely allochthonous established the importance of the sediment column as a record of changes through time in the composition and stability of the soils of each catchment. These changes illustrate the influence of:

Population dynamics of Ceratium spp. in three English lakes, 1945–1985

Changes in the annual population densities of Ceratium spp. in three adjacent English lakes, Windermere, Esthwaite Water and Blelham Tarn, are summarised over the 41 year period 1945–1985. In these lakes the genus is represented by two species, C. hirundinella (O.F. Müll) Bergh. and C. furcoides (Levander) Langhans. Although the species have not been distinguished over the entire study period, they have been shown by examination of preserved samples to undergo marked changes of relative abundance in Esthwaite Water. Both long-term (years) and short-term (within year) changes of populations densities of Ceratium spp. are considered in relation to possible controlling factors including recruitment of the inoculum, nutrient enrichment, physical stability and fungal epidemics. Given an early inoculum, the relative success of Ceratium populations in these lakes decreases along gradients of increasing mixed depths, increasing turbulence and decreasing retention times. The potential for good population growth is regulated by energy inputs, lake bathymetry and hydraulic characteristics. The realisation of such growth is governed by nutrient availability and microbial grazing. The significance of large between-year differences of populations of Ceratium spp. for general lake metabolism is illustrated for summers of contrasting production in Esthwaite Water.     

Are Social Inequalities Widening in Generalised and Abdominal Obesity and Overweight among English Adults?

Background

Obesity is now more common in lower socioeconomic groups in developed nations, but the socio-economic patterning of obesity has changed over time. This study examines the time trends in the socioeconomic patterning of generalised and abdominal obesity and overweight in English adults.

Methods

Data were from core annual samples of the Health Survey for England 1993–2008, including 155 661 participants aged 18–75 years. The prevalence of generalised and abdominal obesity and overweight was reported as crude and age-adjusted estimates. Binomial regression was used to model measures of obesity and overweight with age, sex, survey years, and two indicators of socioeconomic position: Registrar General’s Social Class (manual and non-manual occupational groups) and relative length of full time education. Trends in socioeconomic patterning were assessed by formal tests for interactions between socioeconomic position measures and survey periods in these models.

Results

The prevalence of generalised and abdominal overweight and obesity increased consistently between 1993 and 2008. There were significant differences in the four outcomes between the two socioeconomic position (SEP) groups in men and women, except for generalised and abdominal overweight with social class in men. The prevalence of obesity and overweight across the whole period was higher in subgroups with lower SEP (differences of 0.2% to 9.5%). There was no significant widening of the socioeconomic gradient of most indicators of greater body fat since the early 1990s, except for educational gradient in generalised obesity in men and women (P = 0.001).

Conclusions

Substantial social class and education gradients in obesity and overweight are still present in both sexes. However, there is limited evidence that these socioeconomic inequalities have changed since 1993.     

Ethnicity and class identity: The case of French‐ and English‐speaking Canadians*

This study addresses the racial and religious contexts of identity formation among Lebanese immigrants to the United States of America and Somali immigrants to Canada. Each enters with a different racial status: Lebanese as white; Somalis as black/visible minority. Ethnographic interviews explore the strategies of adaptation and identity development within these groups. Specifically, we compare and contrast the Lebanese and Somali experience through an analysis of ethnic relations in the country of origin, the conditions of immigration, and through accounts of their encounters and identity negotiation with the host society. We demonstrate the strategies each group implements to negotiate both race and religion in identity development. Our findings reveal that each group attempts to make their religious identity evident, however, Somali immigrants must negotiate the effects of ‘othering’ processes with both race and religion, while Lebanese immigrants build a religious identity from privileges afforded to them by virtue of their white racial status.     

Towards understanding: antisemitism and the contested uses and meanings of ‘Yid’ in English football

This article addresses an omission in the currently brief body of work on antisemitism in football and contributes to and advances wider sociological debates in the sub-disciplines of race and ethnicity, religion, linguistics and sport. The article examines antisemitic discourse in English football and in doing so, explains the different uses and meanings of ‘Yid’ in the vernacular culture of fans. While many conceive of ‘Yid’ as an ethnic epithet, fans of Tottenham Hotspur – Gentiles and Jews – have appropriated and embraced the term, using it to deflect the antisemitic abuse they are targeted with due to their ‘Jewish identity’. The study maps the contested uses of ‘Yid’ on a continuum to explain and demarcate between the nuanced forms of antisemitism in football. It makes central the cultural context in which ‘Yid’ is used, together with the intent underpinning its use, since epithets and slurs are not simply determined by their lexical form.
