In the current scenario of energy challenges, natural gas (NG) and associated liquids such as liquefied petroleum gas (LPG) are considered to be clean energy sources compared with coal and oil. Liquefaction is one of the most feasible and safe approaches for transporting NG from the site of production to the site of consumption. However, NG processing to produce liquefied natural gas (LNG) and LPG is extremely costly in terms of both operating and capital expenses because it requires a tremendous amount of energy, particularly at offshore sites. We have developed a new liquefaction process that uses N2 self-recuperation rather than external precooling with 80% less energy consumption than that required by existing single N2 expander processes. In this work, we evaluate the use of an innovative self-recuperative expander-based integrated process to produce LNG–LPG–pentane plus (condensate) at an offshore site in an energy-efficient manner with minimal capital expenditure. Thermodynamic and economic analyses were performed to evaluate the commercial feasibility of the proposed process. Furthermore, the environmental impact in terms of CO2 emissions was calculated. This study reveals that LNG–LPG can be produced at a specific energy expense of 0.2362 kW with a payback period of 1.38 years.
Beziehungen können wesentlich zum persönlichen und beruflichen Lebenserfolg von Jugendlichen und jungen Erwachsenen beitragen. Mit einem Fokus auf der Schnittstelle von Behinderung und Migration ...fragt Chantal Hinni, wie es jungen Menschen gelingt, gemeinschaftliche Werte und Normen in ihr Leben zu integrieren und Beziehungen zu gestalten, die ihnen als Sozialkapital nützlich sind. Sie beleuchtet die bildungssoziologische Frage nach gesellschaftlichen Verteilungsprinzipien im Analyserahmen der Intersektionalität und überführt diese theoretisch und empirisch fundiert in die Anwendung der latenten Klassenanalyse.
Venture capital (VC) syndicates involve repeated transactions among partners and therefore possess network‐like characteristics. Although networks provide access to important externalities, extant ...literature has not studied the effects of the focal firm's resource needs on performance benefits arising from different network structures. We investigate the impact of two proxies for firm‐level resources, namely maturity and status, on the relationship between network cohesion and VC performance. We find that mature and high status VCs benefit less from network cohesion. We also show that maturity and status simultaneously determine the performance effects of network cohesion.
In nur 50 Minuten Karl Marx verstehenWährend die europäische Wirtschaftslage in der ersten Hälfte des 19. Jahrhunderts vornehmlich von der klassischen Nationalökonomie und dem entsprechenden ...Wirtschafsliberalismus geprägt wird, entwickelt sich in der zweiten Hälfte des Jahrhunderts unter Federführung von Karl Marx und Friedrich Engels mit dem Historischen Materialismus eine Weltanschauung, die die Probleme des noch jungen Kapitalismus anprangert. Mit dem Menschen im Mittelpunkt seiner Philosophie definiert Marx klassische Konzepte (wie etwa Produktwert, Preisbildung, Gewinnverteilung, Religion oder die Stellung der Arbeiter in der Gesellschaft) neu und stellt Prognosen für die wirtschaftliche Zukunft an, die teils noch heute aktuell sind. Schließlich ruft er auch mit dem bekannten "Proletarier aller Länder, vereinigt euch!" zur Revolution des Proletariats auf.Nach 50 Minuten wissen Sie: •alles über Marx' Leben und Zeitgenossen •wie Marx zur Wirtschaftsgeschichte beigetragen hat •was es an Marx' Werk zu kritisieren gibt und wie man es ergänzen könnte Diese übersichtliche Einführung will Interesse an den Theorien bekannter Ökonomen wecken und gibt einen informativen Überblick über ihre Themen.

The present study investigates the relationship of PsyCap with objective and subjective career success. Based on conservation of resources theory (COR Theory) and psychological capital theory (PsyCap ...Theory), we assume that career-specific resources, in particular protean career attitude, career planning, and internal and external networking, are important mechanisms that mediate the relationship between PsyCap and both outcomes. We tested our assumptions by means of time-lagged path analysis with R and the lavaan package in a sample of 1110 German academic scientists. Our results indicate a positive relationship between PsyCap and career success. However, we found differential effects regarding the assumed mediation for subjective and objective career success. The effect of PsyCap on subjective career success is mediated by protean career attitude and career planning. The effect of PsyCap on objective career success is mediated by external networking. Our results strengthen the research of PsyCap as a predictor of career success. However, the results also imply that the relationship between PsyCap, career-specific resources, and both aspects of career success is more complex than expected.
The purpose of this paper is to empirically investigate the effects of intellectual capital (IC) on technical innovation (TI) and entrepreneurial orientation (EO) in small and medium‐sized ...enterprises (SMEs).
Hypotheses were tested using a survey data set of 464 questionnaires collected from senior, middle, and functional managers, in addition to employees working in 63 SMEs operating in Jordan.
The findings show that all IC dimensions have positive significant effects on both TI as well as EO. More specifically, human capital and relational capital emerged as having the strongest effects on TI, whereas relational capital and human competence had the strongest effects on EO. Interestingly, relational capital was the only IC dimension that had a particularly strong and positive significant effect on both EO and TI. Moreover, all EO dimensions had positive significant effects on TI. As for the mediating effect of EO, it was found to have quite a strong and partial mediating effect on the relationship between each IC dimension (relational, structural, human, and human competence) and TI. It was also noted that EO had a particularly strong partial mediating effect on the relationship between structural capital and TI, as well as human competence and TI.
Given the unique context within which SMEs are established and developed, in terms of heavily investing in IC, as well as their supposedly entrepreneurial and innovative nature, this study provides an original contribution to the TI literature.
To gain a more nuanced understanding of social mobility in a globalized world, in this article I suggest studying the link between social and spatial mobility by exploring social positions in ...relation to international migration. While migration is often portrayed as a gateway to social mobility, migration scholars have highlighted that transnational spaces and intersecting inequalities may shape social mobility in complex ways. However, little is known about the subjective experiences of spatial and social mobility. Therefore, based on a study of subjective social positions among people who have relocated to Germany, I discuss the implications for a research design that enables social scientists to assess social mobility in contexts of international migration and to explore the spatial dimension in shaping social mobility trajectories. Specifically, I will argue for linking empirical findings from narrative interviews with concepts of space, capitals, and social comparison as well as transnational and intersectional theories. As I will show, this way of inquiring into the social-spatial mobility nexus allows for investigating the complex ways in which spaces affect social mobility, and thus provides a promising gateway to better understand social mobility as a process shaped by both time and space.
'This expert guide to the political economy of Marx's Capital has always been the very best available' - David Harvey This brilliantly concise book is the classic companion to Karl Marx’s most ...well-known work, Capital. In print now for over a quarter of a century, and translated into many languages, this new edition has been fully revised and updated, making it an ideal modern introduction to one of the most important texts in political and economic thought today. The authors cover all central aspects of Marx’s economics. They explain the structure of Marx’s analysis and the meaning of the key categories in Capital, showing the internal coherence of Marx’s approach, and their relevance today. Marx’s method and terminology are explored in detail, with supporting examples. Short chapters set out the significance of Marx’s main concepts and can be grasped easily, making it a practical text for anyone with an interest in understanding Marx’s magnum opus. Discussing Capital’s relevance today, the authors keep abstract theorising to a minimum. This readable introduction highlights the continuing relevance of Marx’s ideas in the light of the problems of contemporary capitalism.
This ambitious book presents a comprehensive new 'macro-monetary' interpretation of Marx's logical method in Capital, based on substantial textual evidence, and concludes that, contrary to the ...prevailing view, there is no 'transformation problem' in Marx's theory of prices of production in Volume III.
This paper analyzes the quantitative contribution of capital-skill complementarity in accounting for rising wage inequality, as in Krusell, Ohanian, Rios-Rull, and Violante (KORV, 2000). We study how ...well the KORV framework accounts for more recent data, including the large changes in labor's share of income that occurred after the KORV estimation period ended. We also study how using information and communications technology (ICT) capital as the complementary capital stock affects the model's implications for inequality and overall model fit. We find significant evidence for continued capital-skill complementarity across all model permutations we analyze. Despite nearly 30 years of additional data, we find very little change to the original KORV estimates of substitution elasticities when the total stock of capital equipment is used as the complementary capital stock. We find much more capital-skill complementarity when ICT capital is used. The KORV framework continues to closely account for rising wage inequality through 2019, though it misses the three percentage points decline in labor's share of income that has occurred since 2000.
