Student dropout is a major concern in studies investigating retention strategies in higher education. This study identifies which variables are important to predict student dropout, using academic data from 3583 first-year students on the Business Administration (BA) degree at the University of Barcelona (Spain). The results indicate that two variables, the percentage of subjects failed and not attended in the first semester, demonstrate significant predictive power. This has been corroborated with an additional sample of 10,784 students from three-degree programs (Law, BA, and Economics) at the Complutense University of Madrid (Spain), to assess the robustness of the results. Three different algorithms have also been utilized: neural networks, random forest, and logit. In the specific case of neural networks, the NeuralSens methodology has been employed, which is based on the use of sensitivities, allowing for its interpretation. The outcomes are highly consistent in all cases: both a simple model (logit) and more sophisticated ones (neural networks and random forest) exhibit high accuracy (correctly predicted values) and sensitivity (correctly predicted dropouts). In test set average values of 77% and 69% have been respectively achieved. In this regard, a noteworthy point is that only academic data from the university itself was used to develop the models. This ensures that there's no dependence on other personal or organizational variables, which can often be difficult to access.

In massive open online courses (MOOCs), recommendation relationships present a collection of associations that imply a new form of integration, such as an interdisciplinary synergy among diverse disciplines. This study took a computer science approach, using the susceptible-infected (SI) model to simulate the process of learners accessing courses within networks of MOOC offerings, and emphasized the potential effects of a network structure. The current low rate of access suggests that a ceiling effect influences learners' access to learning online, given that there are thousands of courses freely available. Interdisciplinary networks were created by adding recommended courses into four disciplinary networks. The diversity of interdisciplinarity was measured by three attributes, namely variety, balance, and disparity. The results attest to interesting changes in how the diversity of interdisciplinary knowledge grows. Particularly remarkable is the degree to which the diversity of interdisciplinarity increased when new recommended courses were first added. However, changing diversity implied that neighbouring disciplines were more likely to come to the forefront to attach to the interdisciplinarity of MOOC offerings, and that the pace of synergy among disparate disciplines slowed as time passed. In the absence of domain experts, expert knowledge is not sufficient to support interdisciplinary curriculum design. More evidence-based analytics studies showing how interdisciplinarity evolves in course offerings could help us to better design online courses that prepare learners with 21st-century skills.

Purpose: After a short historical presentation, this country report highlights current developments of social science education in France and clarifies its general status in the French school system, giving not only information about the curricula baselines, but also on current reforms, shifts and conflict lines among practitioners and researchers. Design/methodology/approach: This article is based on a synopsis of both official documents and evaluation reports published by the French Ministry of Education and other public organs and scientific data such as empirical case studies. Findings: Social sciences education falls under broad purposes such as educating citizens and preparing the future workforce. History, geography and civics are more established and taught to more students than other more recent subjects like "Sciences économiques et sociales" (Economic and social sciences), all of those subjects raising broader research questions.

Key features of open video repositories (OVRs) are outlined, followed by brief descriptions of specific websites relevant to the social sciences. Although most were created by instructors over the past 10 years to facilitate teaching and learning, significant variation in kind, quality, and number per discipline were discovered. Economics and psychology have the most extensive sets of repositories, while political science has the least development. Among original-content websites, economics has the strongest collection in terms of production values, given substantial support from wealthy donors to advance political and economic agendas. Economics also provides virtually all edited-content OVRs. Sociology stands out in having the most developed website in which found video is applied to teaching and learning. Numerous multidisciplinary sites of quality have also emerged in recent years.

Laboratory experiments are a widely used methodology for advancing causal knowledge in the physical and life sciences. With the exception of psychology, the adoption of laboratory experiments has been much slower in the social sciences, although during the past two decades the use of lab experiments has accelerated. Nonetheless, there remains considerable resistance among social scientists who argue that lab experiments lack "realism" and generalizability. In this article, we discuss the advantages and limitations of laboratory social science experiments by comparing them to research based on nonexperimental data and to field experiments. We argue that many recent objections against lab experiments are misguided and that even more lab experiments should be conducted.

The aim of the 15 collaborative projects conducted during the new funding phase of the German research program Modeling and Measuring Competencies in Higher Education--Validation and Methodological Innovations (KoKoHs) is to make a significant contribution to advancing the field of modeling and valid measurement of competencies acquired in higher education. The KoKoHs research teams assess generic competencies and domain-specific competencies in teacher education, social and economic sciences, and medicine based on findings from and using competency models and assessment instruments developed during the first KoKoHs funding phase. Further, they enhance, validate, and test measurement approaches for use in higher education in Germany. Results and findings are transferred at various levels to national and international research, higher education practice, and education policy.

"A unified growth theory is developed that accounts for the roughly constant living standards displayed by world economies prior to 1800 as well as the growing living standards exhibited by modern industrial economies. Our theory also explains the industrial revolution, which is the transition from an era when per capita incomes are stagnant to one with sustained growth.... [The authors] use a standard growth model with...[several] technologies. The first, denoted the 'Malthus' technology, requires land, labor and reproducible capital as inputs. The second, denoted the 'Solow' technology, does not require land. [The authors] show that in the early stages of development, only the Malthus technology is used and, due to population growth, living standards are stagnant despite technological progress. Eventually, technological progress causes the Solow technology to become profitable and both technologies are employed. At this point, living standards improve since population growth has less influence on per capita income growth. In the limit, the economy behaves like a standard Solow growth model.", (excerpt)

Text recycling (hereafter TR), sometimes problematically called "self-plagiarism," involves the verbatim reuse of text from one's own existing documents in a newly created text -- such as the duplication of a paragraph or section from a published article in a new article. Although plagiarism is widely eschewed across academia and the publishing industry, the ethics of TR are not agreed upon and are currently being vigorously debated. As part of a federally funded (US) National Science Foundation grant, we have been studying TR patterns using several methodologies, including interviews with editors about TR values and practices (Pemberton, Hall, Moskovitz, & Anson, 2019) and digitally mediated text-analytic processes to determine the extent of TR in academic publications in the biological sciences, engineering, mathematical and physical sciences, and social, behavioral, and economic sciences (Anson, Moskovitz, & Anson, 2019). In this article, we first describe and illustrate TR in the context of academic writing. We then explain and document several themes that emerged from interviews with publishers of peer-reviewed academic journals. These themes demonstrate the vexed and unsettled nature of TR as a discursive phenomenon in academic writing and publishing. In doing so, we focus on the complex relationships between personal (role-based) and social (norm-based) aspects of scientific publication, complicating conventional models of the writing process that have inadequately accounted for authorial decisions about accuracy, efficiency, self-representation, adherence to existing or imagined rules and norms, perceptions of ownership and copyright, and fears of impropriety.

"This paper explores the responses of fertility and nuptiality to fluctuations in real wages and mortality that can be inferred from annual series of English historical data over the period 1542 to 1800. The paper begins with a review of the time series properties of the data and summarizes the long-term equilibrium relationships identified in previous work.... An investigation is made of the impact of shocks to real wages and mortality on demographic variables as measured by generalized impulse responses and persistence profiles.", (excerpt)

"We propose a model to capture the escape from the Malthusian trap in the longrun. Our aim is to emphasize the key role of endogenous technological progress--as initiated by population growth and education--for longrun economic development. In addition we stress the importance to consider the level of fertility and mortality as the determinants of economic development and not only the rate of population growth. In particular, we may observe different economic growth rates in countries with the same rate of population growth, but differing levels of birth and death rates.", (excerpt)

"We investigate the effects of demographics, household expenditure and female employment on the allocation of household expenditure to consumer goods. For this purpose we estimate an Almost Ideal Demand System based on Dutch micro data. We find that interactions between household expenditure and demographics are of significant importance in explaining the allocation to consumer goods. As a consequence, consumer goods such as housing and clothing change with demographic characteristics from luxuries to necessities.", (excerpt)

"To study the influence of the city on the demographic behavior of rural people, family genealogies extending back to the beginning of the eighteenth century were reconstructed for a community near the city of Geneva [Switzerland].... The article examines kinship relations and kin network in this community at different ages.... The findings reveal a small kinship group surrounding the stable family unit, with generations overlapping sufficiently to assure the transmission of landed property as well as social reproduction without discontinuity and without the need to appeal to collateral kin for help.", (excerpt)

"Japan's population is aging faster than that of any other country in the world. The unprecedented increase in retirees relative to the size of Japan's work force will force radical change if the nation is to avoid a fiscal crisis, or worse. These seemingly innocent demographic changes will force Japan to shrink its famously high savings rate, reverse its proud trade surplus, send more industry overseas, liberalize its tightly controlled markets, and take on a more active, high-profile foreign policy. Ultimately, these changes will shift the balance of power in East Asia.", (excerpt)

"After an introduction touching on various biographical highlights, this paper summarizes a wide-ranging discussion with Richard Easterlin which occurred in the Autumn of 1996. We considered the Easterlin Hypothesis--its genesis and current status, together with Easterlin's views on attempts to develop measures of relative income--and then moved on to ¿The Fertility Revolution' and questions regarding the applicability of the theory of household choice in modernizing societies. This was followed by a discussion of his early career development and influences on him at that time, ending with ruminations regarding the current state of economics, and the validity of training given to young economists today.", (excerpt)

"In the nineteenth century, the demographic development of the Meierij, a region in the south-east of the Netherlands, was different from that of the rest of modernizing northern Europe. Infant mortality remained high, while it dropped elsewhere. The article shows why the current explanation for high infant mortality, which links a sustained high infant mortality to a change in feeding habits is not valid. Increased fertility due, among other reasons, to a lower marital age offers a better explanation. Changes in economic options open to unmarried women provide the clue. With fewer premarital occupational possibilities, women would have been more inclined to marry, or there would have been less pressure on them to forestall a marriage in order to profit to the full from the occupational options. More and earlier marriages meant more children were born, and also a higher infant mortality rate.", (excerpt)

This paper "summarises some of the major changes which have occurred in international migration to, from, and within Asia in the last two decades....A number of theoretical challenges are put forward regarding the complex interrelationships between international population movements, economic development and social change. The employment of systems approaches, neoclassical economic theory, social networks and institutional approaches, and the potential role of population geography in developing a more comprehensive explanation of the changing dynamics of international migration in the region, are discussed. Also considered are the gender dimension in migration, remittance flows and their consequences, and policy issues.", (excerpt)

"A number of hypotheses concerning remittances from foreign emigrants are developed and tested using questionnaire survey data from Lala, a Lebanese village. According to the theory, a rural family engages in an implicit insurance-type contract with the potential migrant because both are averse to risk.... Results from testing the hypotheses are somewhat consistent with the proposition that, after a period of adjustment, migrants do begin to remit, thereby providing their families with an insurance against the uncertainties of life in the country of origin. However, the level of remittances does not appear to depend on the potential to inherit from a family's wealth. Moreover, families do not seem to invest in their migrants so as to improve their farm lands and to undertake risky agricultural techniques. The long-term remittance commitment of migrants to their residual families suggests that migrants' altruism may be a more significant motivating factor than self-interest."

"Emigration pressures are primarily the result of increasing inequalities between countries which, in turn, are the result of factors internal to less developed countries and their relations with developed countries. Both micro (neoclassical) and macrostructural theories of migration are reviewed. It is argued that the neoclassical theory of migration is often unjustly criticized and is sufficiently robust to incorporate those structural considerations which are at the core of macrostructural theories. Moreover, the neoclassical theory, with slight modification, can incorporate the ¿new economics of migration.' The major empirical problem confronting models of international labor migration is that migration flows are constrained by immigration policy. This policy, in turn, is influenced by various special interest groups. The direction and form of migration flows is conditioned by contemporary and historical relationships between source and destination countries.", (excerpt)

"This article examines Chinese capitalist migration from Hong Kong and Taiwan to Canada which took place under the auspices of the Canadian Business Immigration Program. It begins by setting the context of this migration of Chinese capitalists and their capital through a description of the Program and applying sociological theory to explain the process. More specifically, structural models of migration, world systems, political economy and transnationalism are applied which provide an insight and explanation for this migration. Then the role of the state is examined in relation to mediation and social reproduction. The article ends with a trend analysis of this Chinese capitalist migration and its effect on class, cultural transformation, and race and ethnic relations in Canada.", (excerpt)

"Using anomalies of the Italian case as the basis, the aim of this article is to verify how the theoretical framework [of demographic transition] put forward by Lesthaeghe can be interpreted.... While the changes in mores in the Italy of the economic boom were a component of the large-scale processes of secularization, rationalization and modernization specific to the [first demographic transition], the practices, values and models of the collective imagination characterizing the second phase of Lesthaeghe's [second demographic transition] are marked by a state of mind that cannot be put down to the 'spirit of the age' during the years of large-scale modernization, but to the emancipatory and 'rational' falling away of many of the barriers to the unfolding of individual life destiny over and above that based on class, gender and age.", (excerpt)

"This note examines an important conflict between the theory and evidence on migration in LDCs. While the Harris-Todaro class of models explain the phenomenon of migration mainly by expected income differential between the economically advanced and the backward regions, the actual evidence in some cases suggests that migration could actually rise following a rise in income in backward areas. We resolve this puzzle by analysing migration in the context of the existence of imperfect credit markets in LDCs. We show that under certain plausible conditions, the rate of migration from the rural to the urban areas may actually rise when rural wages rise, as they ease the constraints on borrowing by potential migrants.", (excerpt)

"This paper rejects Veugelers and Klassen's initial suggestion that greater concern with demographic considerations might provide a useful explanation for their empirical finding of a post-1989 change in the unemployment-immigration linkage [in Canada] and offers alternative explanations consistent with economic and, especially, sociological-political theories. It shows how elements of Hawkins's (1988) ¿bureaucratic control' and Simmons and Keohane's (1991) ¿political legitimacy' theories can be combined to explain both continuity and change in Canada's postwar immigration policy.", (excerpt)

"This article critically examines the Lewisian turning point [concerning the availability of unlimited manpower resources] in light of Japan's experience since the mid-1800s. Japan reached its Lewisian turning point around 1960. Contrary to the assumptions of the theory however, the findings for Japan indicate that political factors have been more determinative of the rate of migration than purely economic ones. Prior to its turning point in 1960, international relations, war and forced repatriation were the decisive factors. Recently, though the inflow of foreign workers to fill labor shortages has increased, so also has the outflow of Japanese to accompany direct foreign investment.", (excerpt)
