Can You Gig It? An Empirical Examination of the Gig Economy and Entrepreneurial Activity
Authors: Burtch Gordon , Carnahan Seth , Greenwood Brad N. 
Published: February 2018

We examine how the entry of gig-economy platforms influences local entrepreneurial activity. On the one hand, such platforms may reduce entrepreneurial activity by offering stable employment for the unemployed and underemployed. On the other hand, such platforms may enable entrepreneurial activity by offering work flexibility that allows the entrepreneur to redeploy resources strategically in order to pursue the nascent venture. To resolve this tension, we examine the entry of the ridesharing platform Uber X into local areas. We use two measures of entrepreneurial activity: crowdfunding campaign launches at Kickstarter, the world’s largest reward-based crowdfunding platform, and levels of self-employment from the Current Population Survey. Results indicate a negative and significant relationship between platform entry and both measures of entrepreneurial activity. Importantly, the effect manifests primarily amongst unsuccessful Kickstarter campaigns and unincorporated entrepreneurial ventures, suggesting that gig-economy platforms predominantly reduce lower quality entrepreneurial activity, seemingly by offering viable employment for the unemployed and underemployed. These relationships are corroborated with a first-hand survey conducted with gig-economy service providers.This paper was accepted by Anandhi Bharadwaj, information systems.

Authors: Faleiros Vicente De Paula 
Published: February 2018

Resumo – Este artigo de micro-história reflexiva refere-se à história da mudança do paradigma do Serviço Social funcionalista no processo de reconceituação vivido na Escola de Trabalho Social da Universidade Católica de Valparaíso, no Chile, de 1970 a 1973. Tem por objetivo discutir a fundamentação e a prática do paradigma reconceituado no contexto da experiência chilena de transição para o socialismo com liberdade e da articulação com o marxismo. O relato histórico tem como referência a escrita de uma micro-história na perspectiva de uma análise da totalidade, com base em narrativa pessoal e em documentos da época, conforme sugere Burke (1992), numa perspectiva da sociologia reflexiva (MELUCCI, 2005). A discussão da experiência aponta para a construção de uma articulação do Serviço Social com a ação política comprometida com a transformação das relações de dominação. Palavras-Chave: Reconceituação do Serviço Social; Funcionalismo; Dialética; Experiência Chilena. Abstract – This reflective microhistory article refers to the history of the paradigm shift of the functionalist social service in the process of reconceptualization lived in the Social Work School of the Catholic University of Valparaíso - Chile from 1970 to 1973. Its purpose is to discuss the fundaments and the practice of the paradigm reconceptualized in the context of the Chilean experience of transition to socialism with freedom and this articulation with Marxism. The historical account has as reference the writing of a microhistory in the perspective of an analysis of the totality, based on personal narrative and documents of the time, as suggested by Burke (1992), from a perspective of reflective sociology (MELUCCI, 2005). The discussion of experience points to the construction of an articulation of social work with political action committed to the transformation of relations of domination.Keywords: Social Work Reconceptualization; Functionalism; Dialectics; Chilean experience.
O Movimento de Reconceituação na América Latina e suas expressões internacionais: análise crítica da participação e contribuição do CBCISS
Authors: Aquino Isaura Gomes de Carvalho , Silva Aline Pereira Ribeiro , Vieira Pedro Leonardo Cedrola 
Published: February 2018

Resumo – O presente artigo visa apresentar análises preliminares de resultado de pesquisa acerca da participação e contribuição do CBCISS no Movimento de Reconceituação da América Latina, no período compreendido entre a década de 1960 até 1980. Sendo o CBCISS uma instituição sem participação direta na formação profissional, protagonizou, quase exclusivamente, não só a organização das produções sobre a sistematização da prática e da formação profissionais, como também foi responsável pela divulgação do material coletado em âmbito mundial. Organizou os seminários de teorização do Serviço Social, dos quais foi estudado, nesta fase da pesquisa, o Documento de Araxá, com o objetivo de retomar o Serviço Social na história, através de mediações determinantes, possíveis em face do acúmulo teórico-metodológico produzido pelo Serviço Social na esteira da “intenção de ruptura”. Palavras-Chave: movimento de reconceituação; CBCISS; análise crítica. Abstract – This article aims to present preliminary analyzes of research results on the participation and contribution of the Brazilian Center for Cooperation and Interchange in Social Services (CBCISS, in Portuguese) in the Latin American reconceptualization movement between 1960 and 1980. The CBCISS is an institution with no direct participation in professional training, but it was, almost solely, not only the organizer of the academic production on the systematization of professional practice and training, but also the responsible for the dissemination of the collected material worldwide. It organized seminars on the theory of social work, of which it was studied in this research a 1967 seminar in Araxá, Minas Gerais. This choice had the purpose of recovering social work throughout history, through determinant mediations, possible in face of the theoretical and methodological accumulation produced by social work in the wake of the “intention of rupture.” Keywords: reconceptualization movement; CBCISS; critical analysis.
“Entre o assistir e o cuidar”: tendências teóricas no Serviço Social brasileiro
Authors: Passos Rachel Gouveia 
Published: February 2018

Resumo – O presente artigo é fruto das reflexões que compõem a pesquisa de pós-doutoramento. Tem-se como objetivo contribuir para a compreensão da diferença entre assistência e cuidado a partir de uma análise marxista. Na atualidade, essas categorias encontram-se esvaziadas de sentidos teóricos, principalmente nas políticas de saúde e assistência social, uma vez que o irracionalismo contribui para esse esvaziamento. Nesse caminho, o artigo divide-se em três partes: no primeiro momento, abordaremos o conceito de assistência a partir de autoras que já tratavam sobre o assunto no Serviço Social desde os anos 1980. No segundo momento, desenvolveremos a concepção de cuidado que parte do marxismo, além de dissertarmos sobre o cuidado social e o care social. Por fim, serão apresentadas as principais concepções de cuidado que perpassam o Serviço Social brasileiro. Palavras-Chave: assistência; cuidado; Serviço Social. Abstract – This article is the result of the reflections composing a postdoctoral research. The objective is to contribute for an understanding of the difference between assistance and care based on a Marxist analysis. At present, these categories are in general emptied of theoretical meanings, mainly in the policies of health and social assistance, since irrationalism contributes to this emptying. In this way, the article is divided in three parts: first, we will approach the concept of assistance from authors who have already dealt with the subject of social work since the 1980s. Second, we develop the concept of care according to Marxism, in addition to lecturing on different definitions of “social care.” Finally, the main meanings of care that permeate Brazilian social work will be presented. Keywords: assistance; care; social work.

Indícios para a história do Serviço Social a partir da Justiça de Transição
Authors: Backx Sheila De Souza 
Published: February 2018

Resumo − Este trabalho decorre da pesquisa (recente e em curso) intitulada Mulheres na linha de frente, que faz uma articulação entre violência estatal e violência de gênero às práticas de tortura perpetradas no período da ditadura civil-militar no Brasil (1964-1985), no âmbito do estado do Rio de Janeiro. No decorrer desse estudo, foram encontrados dados que possibilitam situar o Serviço Social na história – apesar de não ser seu objeto privilegiado. Assim, a partir de evidências reveladas pelo campo da Justiça de Transição pode-se melhor avaliar a participação de assistentes sociais nos movimentos de resistência desse período da formação social brasileira, a partir de um corpus documental identificado pelas Comissões de Verdade, Memória e Reparação. Palavras-Chave: Serviço Social; história; justiça de transição; movimento social. Abstract − This work stems from a recent (and ongoing) research entitled Women on the front line, which links state violence and gender violence to torture practices perpetrated during the period of the civil-military dictatorship in Brazil (1964-1985), in the state of Rio de Janeiro. In the course of this study, data have been found that make it possible to situate social work in history – although not as its privileged subject. Thus, from evidence revealed by the field of transitional justice, it is possible to evaluate better the participation of social workers in the resistance movements of this period of social formation in Brazil, based on a documentary corpus identified by the Commissions of Truth, Memory and Reparation. Keywords: social work; history; transitional justice; social movements.
Fundo público, política social e Venezuela Bolivariana
Authors: Ribeiro Vicente Neves da Silva 
Published: February 2018

Resumo — A formação social venezuelana é caracterizada por sua condição de exportadora de petróleo e o papel cumprido pela renda petroleira internacional captada. Busca-se debater a relação entre renda petroleira, fundo público e política social durante a história recente da Venezuela, marcada sobretudo a partir de 1999 pelo processo bolivariano. A partir de uma discussão teórica mais geral sobre fundo público e política social, busca-se compreender a especificidade assumida no período recente na Venezuela, tendo em vista o aumento da renda petroleira disponível e a centralidade atribuída à questão social pelo governo bolivariano. Como conclusão indicamos a relação entre a população trabalhadora excedente e a renda petroleira como um traço marcante do processo bolivariano, bem como a presença de significativa fuga de capitais. Palavras-chave: Venezuela; Renda Petroleira; Fundo Público; Política Social; Processo Bolivariano. Abstract — The Venezuelan social formation is characterized by its condition of oil exporter and the role fulfilled by the international oil rents. This paper seeks to discuss the relationship between oil rents, public fund and social policy during the recent history of Venezuela, marked since 1999 by the Bolivarian process. From a more general theoretical discussion on the public fund and social policy, it is sought to understand the specificity assumed in the recent period in Venezuela in view of the increase of available oil rents and the centrality attributed to the social question by the Bolivarian government. As a conclusion, we indicate the relation between the surplus working population and the oil rents as an important feature of the Bolivarian process as well as the presence of significant capital flight. Keywords: Venezuela; Oil Rent; Public Fund; Social Policy; Bolivarian Process.
Comparison of gait kinetics in total and unicondylar knee replacement surgery
Authors: Miller S , Agarwal A , Haddon WB , Johnston L , Arnold G , Wang W , Abboud RJ 
Published: February 2018

Introduction The aim of this study was to compare kinetical data from gait analysis of patients who have undergone total and uni-condylar knee replacement. Materials and methods Thirteen patients with unilateral total knee arthroplasty (TKA) and 13 unicondylar knee arthroplasty (UKA), were included, all performed by the same surgeon more than one year prior. The Vicon gait analysis system was used. Statistical power was calculated using SPSS. Results No significant difference was found in the spatiotemporal parameters of gait and survival years of the knee prosthesis between the two groups. The UKA group was found to have significantly larger moments than the TKA group in knee adduction on the operated side and knee flexion moment on the unoperated side during the loading phase. The maximum and minimum sagittal plane moments of the operated sides in the TKA group were significantly lower than the unoperated side. The difference was most significant at pre-swing. The maximum and minimum moments on the operated sides in the UKA group were significantly lower for the knee flexion and adduction moments when compared with the unoperated side and were most prevalent during the loading phase. Conclusions These results are relevant in terms of prosthesis wear. The TKA knees had smaller magnitude moments than the UKA knees in the sagittal and coronal planes. This could explain the higher revision rates for UKA. In both groups, the non-operated knees had significantly larger moments than the operated knees, which implies that after unilateral knee replacement of either type, the non-operated knee is being put under greater stress.
The use of a novel adhesive tissue patch as an aid to anastomotic healing

Published: February 2018

Introduction One of the most feared complications of colorectal surgery is anastomotic leak. Numerous techniques have been studied in the hope of decreasing leakage. This study was designed to assess the handling characteristics of a novel adhesive tissue patch (TissuePatch™; Tissuemed, Leeds, UK) applied to colorectal anastomoses in a pilot study. This was with a view to assessing its potential role in aiding anastomotic healing in subsequent trials. Methods A patch was applied to colorectal anastomoses after the surgeon had completed the anastomosis and prior to abdominal closure. Handling characteristics and patient outcomes were recorded prospectively. Results Nine patients were recruited before the study was prematurely terminated. In one patient, the patch fell off and in another patient, the surgeon omitted to apply it. Six patients had significant postoperative problems (1 confirmed leak necessitating return to theatre and excision anastomosis, 3 suspicious of leak on computed tomography delaying discharge, 2 perianastomotic collections). One patient had an uneventful recovery. Conclusions Although the handling characteristics of this novel tissue patch were deemed satisfactory, it appears that wrapping a colorectal anastomosis with an adhesive hydrophilic patch has significant deleterious effects on anastomotic healing. This could be a consequence of the creation of a microenvironment between the patch and the anastomosis that impairs healing. Further research is required to better understand the mechanisms involved. At present, the use of such patches on colorectal anastomoses should be discouraged outside the confines of a well monitored trial.
Cervical tuberculous lymphadenitis: diagnosis and demographics, a five-year case series in the UK
Authors: Moualed D , Robinson M , Qureishi A , Gurr P 
Published: February 2018

Introduction Cervical tuberculous lymphadenitis is a low-volume condition in the UK with a potential for delayed diagnosis. This study describes typical demographic and clinical features of patients diagnosed with cervical tuberculous lymphadenitis in a UK population. The utility of cytological, histological and microbiological investigations is reviewed with comparison between fine-needle aspiration and open biopsy. This information can facilitate recognition of new cases and guide initial management. Methods Patients diagnosed with cervical tuberculous lymphadenitis between January 2009 and December 2013 at two district general hospitals were identified from local infectious disease databases. Retrospective case-note review was undertaken to collect demographic and diagnostic data and associated complications. Results Full data were available for 51 patients aged 19–70 years (mean 32.4 years) with mean follow-up of 370 days; 49/51 patients were immigrants to the UK with a wide geographic spread in the countries of origin and time since arrival; 42/51 had no significant comorbidities, although two patients had coexistent HIV infection. The clinical presentation was most frequently without constitutional symptoms (39/51) and often with no history of tuberculosis contact. Posterior triangle neck nodes were most commonly involved (26/51). Conclusion The ‘typical’ patient with cervical tuberculous lymphadenitis in our region is a young healthy individual who came to the UK from a high-risk country several years earlier. Diagnosis by fine-needle aspiration is as effective as open biopsy if fluid/pus is aspirated. Open biopsy is potentially associated with complications but does not appear to increase chronic wound discharge rates in our series.
Routine blood group and antibody screening prior to emergency laparoscopy
Authors: Barrett-Lee J , Vatish J , Vazirian-Zadeh M , Waterland P 
Published: February 2018

Introduction Studies show that rates of blood transfusion associated with general surgical laparoscopy are low. Currently, there are no national guidelines in the UK regarding blood group and antibody screening (G&S) for patients undergoing emergency laparoscopy. The aim of this study was to assess whether using G&S before emergency laparoscopic general surgery routinely is worthwhile by identifying rates of perioperative transfusion. Methods Data were collected retrospectively on all emergency laparoscopic procedures at a single district general hospital between January 2014 and 31 December 2016. Emergency laparoscopic general surgical cases were included and gynaecological cases excluded. Records were reviewed to ascertain whether G&S was performed, whether antibodies were detected and whether patients were transfused. Results A total of 562 emergency laparoscopic cases were performed. The median age was 28 years (range: 6–95 years). Laparoscopic appendicectomy (n=446), diagnostic laparoscopy (n=47) and laparoscopic cholecystectomy (n=25) were the most common procedures. Of the total patient cohort, 514 (91.5%) and 349 (70.1%) had a first and second G&S respectively while 30 (5.3%) had no G&S. Four patients (0.71%) had antibodies detected. One patient (0.18%) received a transfusion. This patient had undergone laparoscopic repair of a perforated duodenal ulcer and there was no major intraoperative haemorrhage but he was transfused perioperatively for chronic anaemia. Conclusions These results demonstrate a low rate of blood transfusion in emergency laparoscopic general surgery. The majority of these patients had a low risk of major intraoperative haemorrhage and we therefore argue that G&S was not warranted. We propose a more targeted approach to the requirement for preoperative G&S and the use of O negative blood in the event of acute haemorrhage from major vessel injury.
The host-guest relationship is the key to sustainable hospitality: Lessons learned from a Dutch case study
Authors: Cavagnaro Elena , Düweke Anna , Melissen Frans 
Published: February 2018

Abstract
As for any other business, our collective challenge to realize sustainable development requires hotels to incorporate the principles of sustainability in their operations and to simultaneously create economic, social and environmental value. Although hotels are increasingly engaged with specific aspects of sustainability, many if not most hospitality professionals still seem to assume that guests are predominantly driven by hedonic and gain motives, view sustainable measures as a threat to their hospitality experience, and are therefore not willing to accept more progressive sustainability measures. This article explores whether this assumption is correct and whether guests are willing and able to focus on sustainability related (normative) values during their stay in a hotel, and thus accept an adjustment to the current host-guest relationship in hotels. By reviewing relevant literature and analysing the results of interviews with hotel guests, this article concludes that as far as the guest is concerned, the host-guest relationship within hotels need not be limited to a purely economic transaction but actually offers room for an open and informed discussion between host and guest on ways to transform this relationship to one that actually supports sustainable development of the hotel sector and wider society. This conclusion will hopefully inform a more mature approach by hotels to the integration of sustainability in their strategy and operations, and a more unreserved and collaborative dialogue with guests about current and future sustainability measures.
The career constructions of hospitality students: A rocky road
Authors: Mooney Shelagh , Jameson Stephanie 
Published: February 2018

Abstract
This article presents the first set of data from an ongoing three-year longitudinal study, which explores how hospitality undergraduates develop a career identity during the course of their studies. Previous, generally quantitative, studies have discovered that many hospitality students choose not to follow a hospitality career after they graduate, however, these studies do not attempt to discover when their career intentions change, nor explain why. The New Zealand study on which the article is based, employed an interpretative, social-constructionist approach informed by intersectional theorizing, using data collected from semi-structured interviews with first-year hospitality and culinary arts degree students. Career construction theory is used to interpret positive or negative career adaptive behaviours and effects are analysed at macro, meso and micro levels. A fusion of global and societal factors and personal characteristics influenced the construction of participants’ professional hospitality identities. Age, gender and ethnicity-based intersections were evident in the ways students developed career adaptive behaviours. A significant contribution of this article is that negative workplace experiences appear to change students’ motivation to follow a hospitality career because they reduce the individual’s belief of being suited to the industry under current prevailing conditions. This finding can shed light on the type of student who is likely to eventually pursue a career in hospitality, the potential role of the internship in the development of career identity and the responsibility of employers. Employers should be aware and validate the idea of ‘the hospitality career as a calling’ by recruiting and developing highly motivated employees and facilitating the development of a professional hospitality identity in their younger workers.
