''Human Resources'': Economics and Organization
The paper considers the current challenges that organizations have to cope with in managing people and knowledge at the present time, moved by turbulent contexts and crisis at a social and at an organizational level. It begins with a question around the possibility of a dialogue between the two disciplines that could jointly contribute to the development of organizational responses, economics and psychology, and it discusses their relationship on the basis of field experiences. In discussing what is nowadays sustainable in the relations between society and organizations, the paper argues the role of intersubjectivity in organizational processes as the resource that allows to cope with unpredictable events and changes both for individuals and groups challenged to live and contribute to their work contexts. Four approaches in organizing the management of technical, economical and social/human resources are presented and analysed in their capacity to offer an interdisciplinary dialogue
Essays on the interdisciplinarity between economics and the neighboring social sciences : historiography, measurement and normativity
The objective of this dissertation is to link three independent essays on the relation of interdisciplinarity economics maintains with the neighboring social sciences. These essays are presented in the condition of a linear research set. This research begins with an essay that performs a bibliographical survey of the economics works touching the subject of interdisciplinarity from manifold perspectives. This essay also presents some insightful numbers regarding the economics literature on the topic. The second essay delves into the bibliographic question and performs a bibliometric effort to measure the evolution of interdisciplinarity within the social sciences network. This essay seeks, through citation analysis, to understand how the interdisciplinarity patterns between the social sciences vary across time and whether these disciplines get closer or farther away from the 1950s onwards. The third essay, at last, answers for a normative defense of economics as an interdisciplinary social science. The argument laid down on this essay is substantiated on Laurence BonJour’s philosophy of science, the so-called coherentism. Its objective is to defend that economics would become more epistemologically able to explain the social phenomena concerning the discipline if its theoretical body opened more space to theories and methods germane to the neighboring social sciences.
Experimental study on bond behavior between high-strength grout and deformed steel bars
Abstract Engineers use high-strength grout to connect precast concrete members for its low shrinkage and good fluidity. This paper designed 87 central pull-out specimens using the control variable method to investigate the influence of factors on the rebar-grout bond property such as compressive strength, steel grade, bar diameter, transverse stirrups, and bond length. The test result showed that improving grout compressive strength (85.8 MPa–122.7 MPa) cannot improve the bond strength, which was different from the previous conclusions of concrete pull-out tests. Simplified formulas were presented for calculating the characteristic values of bond strength, residual strength, peak slip, and relative slip of load-holding platform based on parameter analysis. Then, a constitutive model was proposed to predict the full-range bond stress-slip curve of high-strength grout and steel bar specimens from bearing to failure. Finally, FEA models were established to evaluate the applicability and accuracy of the constitutive model.
