Disciplines and the Categorization of Scientific Truth: The Case of Social Sciences in the Hebrew Wikipedia

For the general audience, Wikipedia is considered the source of “truth,” especially for scientific knowledge. While studies of Wikipedia usually focus on the accuracy of the knowledge within it, few studies have explored its hierarchy and categorization. This study aims to describe how scientific information is organized into disciplines in Wikipedia. I take as a case study the Hebrew Wikipedia and examine the representation and interrelations of five social sciences: sociology, anthropology, economics, political science, and psychology. I gather data from Wikipedia entries categorized under each of these disciplines and create a network that contains categories and subcategories derived from these entries. Using network analysis techniques, I estimate the strength of the relations between the disciplines. Results indicated that while sociology, anthropology, and political science are strongly linked to each other, psychology and economics are relatively isolated. As there is a hierarchical difference between these disciplines, the result is a hierarchical value of the scientific knowledge presented in these Wikipedia entries. An interesting case is the distance between economics and sociology, since under the subcategory “Inequality,” the entries are uniquely categorized under sociology or economics but rarely under both categories. I claim this is an example of a fractal walking the distinction between the two disciplines

Second-Chance Alternatives and Maintained Inequality in Access to Higher Education in Israel

Students are expected to obtain a matriculation diploma during their high school years. Throughout the world, it is considered as a precondition to gaining access to higher education. However, those who failed to meet this criterion can employ, in some cases, “second-chance” alternatives—either to obtain a diploma at an older age, or to enter specific academic programs that do not require one. The literature on second-chance alternatives tends to concentrate on these programs’ evaluation. It rarely addresses the overall effect of these programs on inequality of educational opportunities (IEO). The current study focuses on Israelis who failed to gain a matriculation diploma at their high school graduation and contemplate on the effects that ethnic differences between them play on their chances to enter higher education. Based on a new Panel survey (2012–2016), we found that Israelis from affluent ethnic backgrounds were able to increase their chances to access higher education using “second-chance alternatives”. Those from minority groups, most notably Arabs, were less likely to benefit from these alternatives. While originally aimed at improving higher education enrolment for people from disadvantaged backgrounds, these “second-chance alternatives” resulted in an increase of ethnic-based IEO. Considering the lower rates of Israelis who utilise them, we deduct that these programs “failed” to accomplish their original purpose. However, we argue that they merit further research since their understanding can benefit researchers and policy makers

Second-Chance Alternatives and Maintained Inequality in Access to Higher Education in Israel

Abstract Access to higher education (HE) has a long history. To offer a view on the current debates and worldwide issues regarding access to HE, this editorial depicts how the control of educational access has historically been used as an instrument of governance at the interface of two processes: social stratification and the territorialisation of politics. Access to HE has remained embedded in these large structural processes even though HE has expanded from a highly elitist institution into mass education systems with equity of educational opportunities having become a desirable goal across societies. Analysing these processes helps understand the complex mechanisms producing inequalities in HE today, which are brought together by the ten articles composing this special issue. Tacking stock of how inequalities in access are produced in different continents, countries, HE Institutions, applying to different social groups though evolving mechanisms, these articles document the importance of contrasting methodological and theoretical approaches to produce comprehensive knowledge on this sensitive issue for democratic societies

More Necessary and Less Sufficient: An Age-Period-Cohort Approach to Overeducation in Comparative Perspective

In many countries, the skilled labor market has lagged educational expansion. As a result of increased competition, younger cohorts of the highly educated face decreasing returns to education or overeducation. Surprisingly, decreasing occupational outcomes do not coincide empirically with the economic returns among those with tertiary education. Regarding the process of changes in economic returns to education based on cohort transformations, we expect that the expansion of tertiary education affects specific cohorts, which find themselves facing more labor market competition. As a result, the economic returns to education should decrease among younger cohorts even when the overall returns to education remain stable over time. To study this process, we model economic returns with a new age-period-cohort-trended lag (APCTLAG) method, which allows us to compare the gap in economic returns between tertiary and less than tertiary education over cohorts. Using the Luxembourg Income Study (LIS), we analyze trends over three decades in 12 countries. Our results confirm that educational returns for tertiary education have declined over time, even though the gap between the educated and the less educated has remained similar in most of the countries. For younger cohorts, tertiary education has become more necessary to survive in the competitive labor market, but the actual economic returns have decreased—making tertiary education less sufficient than before

The persistence of the gender earnings gap: cohort trends and the role of education in twelve countries

Studying twelve countries over 30 years, we examine whether women’s educational expansion has translated into a closing gender earnings gap. As educational attainment is cohort-dependent, an Age-Period-Cohort analysis is most appropriate in our view. Using the Luxembourg Income Study (LIS) data, we show that while in terms of attainment of tertiary education women have caught up and often even outperform men, substantial gender differences in earnings persist in all countries. These results are consistent with the composition of the top earnings decile. Using Blinder-Oaxaca decomposition methods, we demonstrate that the role of education in explaining the gender earnings gap has been limited and even decreased over cohorts. Contrary, employment status as well as occupation explain a more substantial part in all countries. We conclude that earnings differences at levels far from gender equality likely also persist in the future, even if the “rise of women” in terms of education continues

Increasing Inequality in Joint Income and Wealth Distributions in the United States, 1995 to 2013

The study of joint income and wealth distributions is important to the understanding of economic inequality. However, these are extremely skewed variables that present tails containing strategic information that usual methods – such as percentile grouping – cannot easily underline. In this paper, we propose a new method that is able to provide a thorough examination of tails: the isograph and the logitrank. These tools entail a more detailed conception of inequality by describing inequality at different points of the distribution. Using US data 1995-2013 from the Luxembourg Wealth Study (LWS), we find first that income inequality increased significantly, in particular in the upper middle classes. Second, the wealth- to-income ratio measuring the importance of wealth relative to income, increased significantly. The association between high wealth and high incomes, fourth, increased as well. Based on our analysis, we can conclude that this increase in the association between wealth and income is not a trivial consequence of increasing inequality, but a stronger coherence of the diagonal at the top of the income and wealth distributions
