Abstract This paper examines contemporary Kenyan popular fiction as a site of cultural production, where the contradictions of African modernity are played out. The paper focuses on one of Kenya's oldest popular fiction columns, Whispers, published in local newspapers since 1983. Constructed around a Kenyan family, which is deployed as an allegorical trope to read modern Kenya, the paper explores how the column introduces us to the anxieties that define life in contemporary Kenya. Although the narrative comprises many thematic concerns, reference is particularly made to the restive masculinity threatened by social change. The paper also provides a discussion of the constant ‘backward glance’, an attempt to look for stability in the past, part of the society's relentless search for models that could help Kenyans make sense of an uncertain present, and an even more doubtful future. The paper also engages with the narrative mode of this fiction, examining how humour, satire and parody deceptively make light of what are important issues affecting society. 相似文献

Research has shown a connection between being a college sports fan and binge drinking; however, no research uses criminological theories when examining this connection. The purpose of the present study is to examine the ability of self-control and differential association theories to determine whether the relationship between college sports fans and binge drinking is individual or group situated. Using self-report data from (n = 693) college students from four southern universities, the results show that the connection between being a college sports fan and binge drinking can be accounted for by both low self-control and differential association. These results are discussed and policy implications are presented. 相似文献

We test hypotheses regarding generational differences in the effects on organizational loyalty of workplace insecurity, restructured workplace temporalities, and technological access to the workplace. We argue that large-scale social changes have eroded the social employment contract and impacted these features of the workplace. Further, these new working conditions will have a greater impact on the organizational loyalty and commitment of older cohorts of workers whose expectations were formed under the previous social contract than on more recent cohorts. With the exception of insecurity, our results generally support our hypotheses. They also have some intriguing implications that the conditions that dampen the loyalty of older cohorts enhance that of younger. Likewise, they raise important questions about what factors affect the loyalty of younger generations of workers and what role the increasing reliance on technology for work outside of “normal” working hours might play in fostering loyal employees. 相似文献

Abstract This study of sore throats in a college population revealed predominately mild physical abnormalities and a low incidence of group A beta hemolytic streptococci. A concern is raised about the criterion for the interpretation of the bacitracin disc test. In the endemic or usual circumstance, the generally healthy adult complaining of sore throat while living in a good environment and having no major physical findings has an acute rheumatic fever risk approaching zero. The risk of an adverse reaction to penicillin would appear to be greater. The physician must consider the host, the environment, and the epidemiologic factors that may affect the rheumatogenicity of the organism. In light of these ambiguities, the practicing physician should reevaluate the medical ritual of throat culturing. 相似文献

Per capita consumption of energy in 112 world areas was related to a series of economic and demographic variables. Linear associations were found for four economic variables, and a curvilinear association in the form of a J curve for four demographic variables. It was found that the exponential distribution y = e(-X) for the curves for the demographic variables (crude birth rate, infant mortality rate, percent of deaths from contagious and infectious diseases, and life expectancy). By using a table of exponential functions, one can determine values for the distribution of these variables and the crude death rate for any desired level of energy consumption. 相似文献

Kindergarten oral language skill: A key variable in the intergenerational transmission of socioeconomic status 总被引:1,自引:0,他引:1

In this paper we test whether oral language development during the preschool years helps explain the positive relationship between family socioeconomic status (SES) and children's elementary school performance. In particular, we test for the portion of the SES effect on 2nd to 4th grade reading, 3rd to 4th grade mathematics, and overall teacher-rated performance that is explained by oral language ability measured when kindergarten begins. We analyze a unique data set containing unusually comprehensive measures of kindergarten oral language ability. The data are for white Midwestern children and their families. Estimation via structural equation modeling shows that oral language skill at kindergarten entry explains most of the effect of SES on elementary school performance. Since other studies have shown that elementary school performance strongly determines later educational attainment, much of the intergenerational transmission of socioeconomic status occurs when the child is very young. 相似文献

The study seeks to ascertain whether the operational definition of “gentrification” has an impact on the apparent extent, location and causal factors associated with the phenomenon. Four alternative definitional criteria are specified, based on areal changes in: proportion black, proportion college-educated, real incomes and real property values. The stringency of the given change needed to qualify as gentrification is also varied. Census tract changes from 1970–80 in Philadelphia are analyzed. Results indicate great sensitivity in the number and location of “gentrified” tracts to the definition chosen and stringency applied. Even more importantly, the 1970 characteristics of tracts which statistically explain their subsequent gentrication vary dramatically across these definitions. 相似文献

Summary An age-structured population dynamics model is presented that incorporates pheromone-trapping and food-trapping as control
methods for an insect pest. The model yields the following results. Low rates of pest survivorship allow lower trapping rates
for control. Species with long developmental periods are easier to control than those with shorter developmental periods (other
factors being equal) due to lower net survival. The rates of pheromone trapping alone for effective control are usually very
high. The combination of pheromone and food trapping allows control with much lower trapping rates than either method alone.
Even small amounts of immigration of adult pests into the control area renders pheromone control ineffective, whereas food
traps suppress both the immigrants and the resident population. Food- (or odor-) baited traps which attract both males and
females are only somewhat more efficient than those which attract females alone. The existence of density-dependent population
regulation assists the control program substantially, but this assistance declines as food trapping becomes a more important
part of the control program. Larval competition strongly affects the required trapping rates for eradication; species in which
all larvae exert strong competition are much easier to control than those in whic the younger larvae contribute little to
the total competitive depression. 相似文献
