The embeddedness of social entrepreneurship: Understanding variation across local communities

Social enterprise organizations (SEOs) arise from entrepreneurial activities with the aim of achieving social goals. SEOs have been seen as alternative and/or complementary to the actions of governments and international organizations to address poverty and poverty-related social needs. Using a number of illustrative cases, we explore how variations in local institutional mechanisms shape the local "face of poverty" in different communities and how this relates to variations in the emergence and strategic orientations of SEOs. We develop a model of the productive opportunity space for SEOs as a basis of, and an inspiration for, further scholarly inquiry.social entrepreneurship; Social mechanisms; poverty; opportunity; institutions;

Reconstructive procedure for treatment of trochanteric pressure ulcers in spinal-cord-injured patients

Background: Pressure ulcers are frequent complications for spinal-cord-injured patients and, trochanteric pressure sores, are quite difficult to treat. This site requires to consider some aspects, such as wound dimension, surgical timing, and reconstructive flap choice. Methods: We report our experience from 2011 to 2016 on 82 trochanteric sores in 68 spinal-cord-injured patients. All the cases were treated with two-time procedures. Firstly, we performed the surgical toilette of the wound, and in the second procedure, the reconstruction with a muscle or musculocutaneous flap. Results: Using the two-time procedure, we report no recurrences after a mean follow-up of 3 years. The main complication reported was a seroma that undergo to a spontaneous resolution. Conclusions Conclusions: We believe that the described approach can be useful to treat trochanteric sores and to reduce the recurrence rate. Muscle flaps seem to be superior to fasciocutaneous or perforator flaps in this site. Level of evidence: Level III, therapeutic study

Performative Work: Bridging Performativity and Institutional Theory in the Responsible Investment Field

Callon’s performativity thesis has illuminated how economic theories and calculative devices shape markets, but has been challenged for its neglect of the organizational, institutional and political context. Our seven-year qualitative study of a large financial data company found that the company’s initial attempt to change the responsible investment field through a performative approach failed because of the constraints posed by field practices and organizational norms on the design of the calculative device. However, the company was subsequently able to put in place another form of performativity by attending to the normative and regulative associations of the device. We theorize this route to performativity by proposing the concept of performative work, which designates the necessary institutional work to enable translation and the subsequent adoption of the device. We conclude by considering the implications of performative work for the performativity and the institutional work literatures

Exploring the success factors of hybrid micro-enterprises

This research explores hybrid micro-entrepreneurs’ founding motivations and the transformation of those motivations into visions of success, by applying multiple criteria decision analysis (MCDA). We find that entrepreneurs of hybrid micro-enterprises are driven mostly by noneconomic goals and that those influence their vision of success. The success framework consists of seven indicators (training, professional development, marketing, management, external factors, infrastructures, and organizational aspects). Human capital is perceived as the most important for success – translating the professional motivations for founding. Reversely, external factors, which are usually considered crucial to attain legitimacy, are perceived the least important factors. Given the findings, are hybrid micro-entrepreneurs ready to succeed?info:eu-repo/semantics/publishedVersio

Entrepreneurial sons, patriarchy and the Colonels' experiment in Thessaly, rural Greece

Existing studies within the field of institutional entrepreneurship explore how entrepreneurs influence change in economic institutions. This paper turns the attention of scholarly inquiry on the antecedents of deinstitutionalization and more specifically, the influence of entrepreneurship in shaping social institutions such as patriarchy. The paper draws from the findings of ethnographic work in two Greek lowland village communities during the military Dictatorship (1967–1974). Paradoxically this era associated with the spread of mechanization, cheap credit, revaluation of labour and clear means-ends relations, signalled entrepreneurial sons’ individuated dissent and activism who were now able to question the Patriarch’s authority, recognize opportunities and act as unintentional agents of deinstitutionalization. A ‘different’ model of institutional change is presented here, where politics intersects with entrepreneurs, in changing social institutions. This model discusses the external drivers of institutional atrophy and how handling dissensus (and its varieties over historical time) is instrumental in enabling institutional entrepreneurship

Search for the standard model Higgs boson in the H to ZZ to 2l 2nu channel in pp collisions at sqrt(s) = 7 TeV

A search for the standard model Higgs boson in the H to ZZ to 2l 2nu decay channel, where l = e or mu, in pp collisions at a center-of-mass energy of 7 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 inverse femtobarns. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 270-440 GeV range is excluded at 95% confidence level.Comment: Submitted to JHE

Search for anomalous t t-bar production in the highly-boosted all-hadronic final state

A search is presented for a massive particle, generically referred to as a Z', decaying into a t t-bar pair. The search focuses on Z' resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks, which yield collimated decay products that are partially or fully merged into single jets. The analysis uses new methods to analyze jet substructure, providing suppression of the non-top multijet backgrounds. The analysis is based on a data sample of proton-proton collisions at a center-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 5 inverse femtobarns. Upper limits in the range of 1 pb are set on the product of the production cross section and branching fraction for a topcolor Z' modeled for several widths, as well as for a Randall--Sundrum Kaluza--Klein gluon. In addition, the results constrain any enhancement in t t-bar production beyond expectations of the standard model for t t-bar invariant masses larger than 1 TeV.Comment: Submitted to the Journal of High Energy Physics; this version includes a minor typo correction that will be submitted as an erratu

Combined search for the quarks of a sequential fourth generation

Results are presented from a search for a fourth generation of quarks produced singly or in pairs in a data set corresponding to an integrated luminosity of 5 inverse femtobarns recorded by the CMS experiment at the LHC in 2011. A novel strategy has been developed for a combined search for quarks of the up and down type in decay channels with at least one isolated muon or electron. Limits on the mass of the fourth-generation quarks and the relevant Cabibbo-Kobayashi-Maskawa matrix elements are derived in the context of a simple extension of the standard model with a sequential fourth generation of fermions. The existence of mass-degenerate fourth-generation quarks with masses below 685 GeV is excluded at 95% confidence level for minimal off-diagonal mixing between the third- and the fourth-generation quarks. With a mass difference of 25 GeV between the quark masses, the obtained limit on the masses of the fourth-generation quarks shifts by about +/- 20 GeV. These results significantly reduce the allowed parameter space for a fourth generation of fermions.Comment: Replaced with published version. Added journal reference and DO
