Voice and Inequality: The Transformation of American Civic Democracy

white men now includes a rainbow of persons, and it has just witnessed the first instance of a woman president handing off the gavel to a female successor. Despite the many changes over the decades, there have been important continuities—so many that Goodnow and his colleagues would surely recognize us today as inheritors of the association and disciplinary vision they launched. Now, as then, organized political science encompasses normative theory as well as empirical research. Now, as then, APSA features comparative research, area studies, and a focus on international politics as well as studies of American politics; and our membership is international. APSA fosters both pedagogy and research. We nurture ties to neighboring disciplines and proudly include scholars who started elsewhere in our ranks. Now, as then, we aim to link responsible citizenship in the larger society to scholarly studies of government and politics. In the words of Pendleton Herring, delivered in his APSA presidential address 50 years ago: “[A]s we . develop political science as a discipline we both serve our professional needs and perform the vital function of helping our democracy to know itself better. ” Above all, as Goodnow put it in his first presidential address, APSA aspires to be “inclusive. ” We do not define political science narrowly, and yet we still seek to nurture solidarity and fellowship, especially by sponsoring “annual sessions” that “offer a common meeting ground in more ways than one for those whose work is mainly or largely political rather than economic or historical. ” Ours is a vital association, still benefiting from active member involvement and support, a model of unity nourished by diversity. For 100 years, we political scientists have stuck together and flourished. Let us hope that a century from now our successors can look back and say that we built well on earlier foundations, opening the way for still further growth and intellectual and practical engagement. The centenary of APSA, a thriving voluntary membership group, is a fitting time to reflect on the changing shape of the American civic democracy of which we are a part. U.S. democracy has long been considered distinctive—and a model of sorts for the rest of the world. This is somewhat owing to the U.S. Bill of Rights and electoral contests; perhaps even more so, it is because Americans have long been portrayed as preeminent organizers and joiners of voluntary associations that shape and supplement the activities of government. In the 1890s, Lord Bryce—who later served as the
Japanese solutions to the equity and efficiency dilemma? Secondary schools, inequity and the arrival of ‘universal’ higher education

Any moves towards substantive equality in education must negotiate the contradictions between equality and efficiency. Equality of education comes about through both the widening of opportunity and the maintenance of educational quality, but in the context of limited resources, educational policy rarely serves both ends simultaneously. Regardless of imperatives involved in making particular policy choices, if the resulting outcomes are either too visible or the system is deemed to be too rigid, social inequality emerges as an intractable, highly salient issue. The critical questions for research thus become: How do various approaches to negotiating this central tension differ? How does the choice of strategies produce different results across different education systems? To explore these questions, this paper examines the function and outcomes of educational differentiation in Japan, both at the secondary and tertiary levels, in relation to social inequality. Given that Japan entered an era of ‘universal’ access to higher education ahead of other high‐income countries, it presents an ideal case to reflect on policy choices currently being considered or implemented elsewhere. Through cross‐sectional analyses of three cohorts of Japanese graduates, it reveals that social equality in accessing elite secondary and higher education institutions deteriorates as privatisation of education advances. It concludes that hierarchical structure of secondary and higher education institutions, when coupled with policies advancing privatisation and universalisation, result in negative or inconsequential effects on social equality.
Preventing Input Validation Vulnerabilities in Web Applications through Automated Type Analysis

Web applications have become an integral part of the daily lives of millions of users. Unfortunately, web applications are also frequently targeted by attackers, and critical vulnerabilities such as cross-site scripting and SQL injection are still common. As a consequence, much effort in the past decade has been spent on mitigating web application vulnerabilities. Current techniques focus mainly on sanitization: either on automated sanitization, the detection of missing sanitizers, the correctness of sanitizers, or the correct placement of sanitizers. However, these techniques are either not able to prevent new forms of input validation vulnerabilities such as HTTP Parameter Pollution, come with large runtime overhead, lack precision, or require significant modifications to the client and/or server infrastructure. In this paper, we present IPAAS, a novel technique for preventing the exploitation of cross-site scripting and SQL injection vulnerabilities based on automated data type detection of input parameters. IPAAS automatically and transparently augments otherwise insecure web application development environments with input validators that result in significant and tangible security improvements for real systems. We implemented IPAAS for PHP and evaluated it on five real-world web applications with known cross-site scripting and SQL injection vulnerabilities. Our evaluation demonstrates that IPAAS would have prevented 83% of SQL injection vulnerabilities and 65% of cross-site scripting vulnerabilities while incurring no developer burden.
The Big Picture: A Meta-Analysis of Program Effectiveness Research on English Language Learners

This article presents a meta-analysis of program effectiveness research on English language learners. The study includes a corpus of 17 studies conducted since Willig's earlier meta-analysis and uses Glass, McGaw, and Smith's strategy of including as many studies as possible in the analysis rather than excluding some on the basis of a priori “study quality” criteria. It is shown that bilingual education is consistently superior to all-English approaches, and that developmental bilingual education programs are superior to transitional bilingual education programs. The meta-analysis of studies controlling for English-language-learner status indicates a positive effect for bilingual education of . 23 standard deviations, with outcome measures in the native language showing a positive effect of . 86 standard deviations. It is concluded that bilingual education programs are effective in promoting academic achievement, and that sound educational policy should permit and even encourage the development and implementation of bilingual education programs.
Validity and reliability of the Turkish version of the Smartphone Addiction Scale-Short Version among university students

Objective: The aim of this study was to evaluate the reliability and validity of the Turkish version of the Smartphone Addiction Scale-Short Version (SAS-SV) among university students. Methods: Three hundred and sixty-seven university students using smartphone from Uskudar University are enrolled the study. Sociodemographic information including characteristics of smartphone usage, internet addiction scale and SAS-SV were conducted. SAS-SV consists of ten items and single factor structure. For the examination of structure validity, the Kaiser-Meyer-Olkin and Bartlett’s tests were utilized. In order to check the reliability of each item, Cronbach’s alpha correlation coefficient was confirmed for each item and total. The corrected item-total correlation coefficients and test-retest reliability were also calculated. The concurrent validity was confirmed using Internet Addiction Scale. Results: Cronbach’s alpha coefficient of the scale was 0.867 and had a high reliability. Reliability coefficient of test-retest was 0.926. The SAS-SV was statistically and positively correlated with the internet addiction scale confirming concurrent validity. Participants who evaluated themselves as addicted to smartphones had statistically significantly higher SAS-SV scores than the participants who evaluated themselves as not-addicted. Also the SAS-SV scores were statistically and positively correlated with the frequency of smartphone-checking behavior and the time consumed during smartphone use. Conclusion: SAS-SV is a valid and reliable instrument to evaluate smartphone usage among university students.
Regional undo/redo techniques for large interactive surfaces

When multiple users are simultaneously sharing a workspace, it is not always clear what should happen when a user invokes an undo action. In this paper we explore different user interfaces for undo/redo for co-located collaborative workspaces, such as large interactive whiteboards. A preliminary study revealed that users expect neither a global nor personal undo, but rather a regional undo. We propose and evaluate three automatic regional undo/redo techniques (clustering, workspace, field of view) designed for a large interactive whiteboard. The results of the evaluation showed that an undo technique based on users' field of view was most preferred, while the content-based clustering technique produced most errors. We conclude with potential improvements to the developed techniques, and propose a set of design recommendations for implementing regional undo/redo on large interactive surfaces.
Hypertonic saline challenge tests in the diagnosis of bronchial hyperresponsiveness and asthma in children

The hypertonic saline challenge test is the recommended method to assess bronchial hyperresponsiveness in the International Study of Asthma and Allergies in Childhood (ISAAC). The sensitivity of this procedure to assess asthma symptoms, however, has been reported to vary among study centers. The purpose of our study was to evaluate the value of this provocation test in an epidemiological survey in children, and to relate the degree of bronchial hyperresponsiveness to the severity of asthma symptoms. All 11–13‐year‐old children from 16 randomly selected schools in Linköping, Sweden received a questionnaire regarding respiratory symptoms and allergic disease. Skin prick tests with eight inhalant allergens were performed. In addition, all children with wheeze over the past 12 months (current wheeze) and a random sample of children without current wheeze were invited to perform hypertonic saline provocation tests. A complete data set was available for 170 children, including 50 with and 120 without current wheeze. Bronchial hyperresponsiveness (BHR) was defined as at least 15% decline in FEV1. The degree of BHR was represented by the response/dose ratio, i.e. the fall in FEV1 divided by total dose of inhaled saline. The severity of asthma symptoms was classified by the number of wheezing episodes over the past 12 months. ‘Asthma ever’ was defined by a combination of symptoms in the questionnaires. Children with ‘asthma ever’ and current wheeze were considered as having current asthma. Current atopic asthma was defined as current asthma with at least one positive skin prick test. The sensitivity of the procedure to detect ‘asthma ever’, current asthma and current atopic asthma was 62, 61 and 83%, and the specificity 83, 81 and 60%, respectively. The positive challenge rate was 52, 34, 13 and 7% among current wheezers, previous wheezers, non‐wheezers with a history of allergy and healthy children. The degree of bronchial hyperresponsiveness increased with the number of wheezing episodes. Thus, the median and range of the response/dose ratio were 4.8%/ml (2.1–14.8), 2.6%/ml (0.7–8.6) and 1.3%/ml (0.8–2.7), respectively, for children with ≥ 4 episodes, 1–3 episodes and no wheezing episodes over the past 12 months (p<0.001). In conclusion, hypertonic saline provocation test is useful as a tool to detect asthma in epidemiological studies in children. The degree of bronchial hyperresponsiveness, as represented by the response/dose ratio, reflects the severity of asthma symptoms.
Prostaglandins and Radical Oxygen Species Are Involved in Microvascular Effects of Hyperoxia

Hyperoxia causes vasoconstriction in most tissues, by mechanisms that are not fully understood. We investigated microvascular effects of breathing 100% oxygen in healthy volunteers, using iontophoresis to deliver acetylcholine (ACh) and sodium nitroprusside (SNP). Aspirin and vitamin C were used to test for involvement of prostaglandins and radical oxygen species. Forearm skin perfusion was measured using laser Doppler perfusion imaging. Results were analysed using dose-response modelling. The response to ACh was reduced by 30% during oxygen breathing compared to air breathing [0.98 (0.81–1.15) PU vs. 1.45 (1.30–1.60) PU, p < 0.001]. ED50 values were unchanged [2.25 (1.84–2.75) vs. 2.21 (1.79–2.74), not significant]. Aspirin pre-treatment abolished the difference in response between oxygen breathing and air breathing [maximum: 1.03 (0.90–1.16) vs. 0.89 (0.77–1.01), not significant; ED50: 1.83 (1.46–2.30) vs. 1.95 (1.65–2.30), not significant]. ACh-mediated vasodilatation during 100% oxygen breathing was partially restored after pre-treatment with vitamin C. Breathing 100% oxygen did not change the microvascular response to SNP [1.45 (1.28–1.62) vs. 1.40 (1.26–1.53), not significant]. These results favour the hypothesis that hyperoxic vasoconstriction is mediated by inhibition of prostaglandin synthesis. Radical oxygen species may be involved as vitamin C, independently of aspirin, partially restored ACh-mediated vasodilatation during hyperoxia.
alpha(1)-adrenoceptor subtypes differentially couple to growth promotion and inhibition in Chinese hamster ovary cells.

We have compared the coupling of human alpha(1A)-, alpha(1B)-, and alpha(1D)-adrenoceptors (expressed at approximately 2000 fmol/mg protein in Chinese hamster ovary cells) to cellular growth promotion (as assessed by [(3)H]thymidine incorporation) and related signaling mechanisms. Maximum elevation of intracellular Ca(2+) by the three subtypes occurred with the rank order alpha(1A) (1691 nM) > alpha(1D) (1215 nM) > alpha(1B) (360 nM). In contrast, activation of the ERK, JNK, and p38 forms of mitogen-activated protein kinases occurred with the rank order alpha(1D) > alpha(1A) > alpha(1B). alpha(1A)-Adrenoceptor stimulation inhibited basal and growth factor-stimulated [(3)H]thymidine incorporation by 74%, and this was mitigated by p38 inhibition. In contrast, alpha(1D)-adrenoceptor stimulation enhanced cellular growth by 136%, and this was blocked by two distinct inhibitors of ERK activation. We conclude that within a given cell type alpha(1)-adrenoceptor subtypes can have opposite effects on cellular growth, although their proximal signal transduction displays only quantitative differences.
New Alliances: Why Mainstream Parties Govern with Radical Right-Wing Populist Parties:

This article investigates the recent government participation of a number of radical right-wing populist parties in West European democracies. With the help of coalition formation theories the government coalitions in which these parties have participated are characterised and inferences are made about the reasons for the cooperation between mainstream right and radical right-wing populist parties. The accuracy of these inferences is then examined in more detail by analysing the changing electoral fortunes and party positions of both mainstream and radical right-wing populist parties. These analyses demonstrate that office, policy and votes made mainstream right parties turn to radical right-wing populist parties as new coalition partners and that two important changes in West European party systems have enabled the formation of the new alliances, the first being an electoral shift to the right and the second the convergence of party positions of mainstream right and radical right-wing populist parties.
Students' of Color and European American Students' Stigma‐Relevant Perceptions of University Instructors

In classrooms students of color may experience stigma (i.e., concern about being stereotyped) because negative stereotypes of their intellect are salient. Two studies included African American, European American, and Latina/Latino female and male undergraduates. Study 1 (n = 86) demonstrated while students of color generally had positive expectations of teachers, their expectations declined when imagining class with a European American instructor who would repeatedly versus never evaluate their work or an ethnically matched instructor across conditions. Study 2 (n = 136) revealed all students had more positive expectations of culturally tolerant versus culturally intolerant instructors. Students of color more than European American students perceived that intolerant instructors could grade them unfairly. We discuss implications for ethnically diverse classrooms.
Self-Approaching Paths in Simple Polygons

We study self-approaching paths that are contained in a simple polygon. A self-approaching path is a directed curve connecting two points such that the Euclidean distance between a point moving along the path and any future position does not increase, that is, for all points a, b, and c that appear in that order along the curve, |ac| >= |bc|. We analyze the properties, and present a characterization of shortest self-approaching paths. In particular, we show that a shortest self-approaching path connecting two points inside a polygon can be forced to follow a general class of non-algebraic curves. While this makes it difficult to design an exact algorithm, we show how to find a self-approaching path inside a polygon connecting two points under a model of computation which assumes that we can calculate involute curves of high order. Lastly, we provide an algorithm to test if a given simple polygon is self-approaching, that is, if there exists a self-approaching path for any two points inside the polygon.

China's Official Framing of Religion and Its Influence on Young Chinese Students: A Partial Testing of the Process Model of Framing in a Special Media Environment

Using a multiple-method approach that combines content analysis and experiment, this study tested the first three steps of the process model of framing in China's specific media environment, in which media have a special relationship with the ruling group and the audiences. The study supports the first two steps of the process model and found that the ruling group's view of religion greatly shapes the media's framing of religion, which influences the audiences’ individual framing. The third step that predicts a correlation between the audiences’ individual framing and their individual political attitude, however, is not supported. An interesting phenomenon appeared: students not exposed to the newspaper articles tended more to support the government's dealing with religion as a political issue than did those exposed to one or two newspaper articles.
Occurrence of diarrhoeal diseases in relation to infant feeding practices in a rural community in West Bengal, India

In a rural community‐based prospective study, diarrhoea in relation to the feeding patterns of a cohort of infants was studied. A total of 148 infants between the ages of 0 and 2 months were enrolled and followed until the completion of 1 year of age. Survival analysis showed that by the fourth month of age exclusive breastfeeding dropped by 75%. The proportion of complementary breastfeeding increased from 18.6 to 52.9% during the same period and to 83.7% by the eighth month. This study clearly highlights the tendency for early switch over from exclusive breastfeeding to complementary breastfeeding. Early weaning was associated with an incidence rate ratio (IRR) of 3.02 (95% CI 1.043–8.802). The IRR of 3.02 and its confidence limits (1.043–8.02) suggest a significant protective effect of exclusive breastfeeding against diarrhoea in infants. The results of this study indicate that promotion of exclusive breastfeeding has a potential role to reduce the incidence of diarrhoea amongst infants. The findings of this study will be useful for Diarrhoeal Disease Control Programme in reducing diarrhoeal morbidity.
Vascular regression is required for mesenchymal condensation and chondrogenesis in the developing limb

Vascular regression occurs during limb mesenchymal cell condensation and chondrogenesis, but it is unclear whether it is required for these processes or is a secondary phenomenon without major regulatory roles. To address this issue, beads presoaked with the potent angiogenic factor vascular endothelial growth factor (VEGF) were implanted in the vicinity of the prospective digit 2 in early chick embryo wing buds and the effects on angiogenesis and digit development were determined over time. We found that VEGF treatment caused a marked local increase in blood vessel number and density. Strikingly, this was accompanied by inhibition of digit 2 development as revealed by lack of expression of chondrogenic transcription factor Sox9 and absence of Alcian blue staining. Vascular distribution and skeletal development in adjacent areas remained largely unaffected. Inhibition of digit formation and excess vascularization were both reversible upon further embryonic growth and dissipation of VEGF activity. When supernumerary digits were induced at the anterior limb margin by retinoic acid treatment, their development was also preceded by vascular regression; interestingly, cotreatment with VEGF inhibited supernumerary digit development as well. Direct exposure of limb mesenchymal cells in micromass cultures to VEGF caused no obvious effects on condensation and chondrogenesis, indicating that VEGF effects are not due to direct action on skeletal cells. Our results are the first to provide evidence that vascular regression is required for mesenchymal condensation and chondrogenesis. A model of how patterning mechanisms and vascular regression may intersect and orchestrate limb skeletogenesis is proposed. © 2001 Wiley‐Liss, Inc.
