Challenging Methods and Results Obtained from User-Generated Content in Barcelona’s Public Open Spaces
Authors: Pallares-Barbera Montserrat , Masala Elena , Jokovic Jugoslav , Djukic Aleksandra , Albacete Xavier 
Published: March 2019

AbstractUser-generated content (UGC) provides useful resources for academics, technicians and policymakers to obtain and analyse results in order to improve lives of individuals in urban settings. User-generated content comes from people who voluntarily contribute data, information, or media that then appears in a way which can be viewed by others; usually on the Web. However, to date little is known about how complex methodologies for getting results are subject to methodology-formation errors, personal data protection, and reliability of outcomes. Different researches have been approaching to inquire big data methods for a better understanding of social groups for planners and economic needs. In this chapter, through UGC from Tweets of users located in Barcelona, we present different research experiments. Data collection is based on the use of REST API; while analysis and representation of UGC follow different ways of processing and providing a plurality of information. The first objective is to study the results at a different geographical scale, Barcelona’s Metropolitan Area and at two Public Open Spaces (POS) in Barcelona, Enric Granados Street and the area around the Fòrum de les Cultures; during similar days in two periods of time - in January of 2015 and 2017. The second objective is intended to better understand how different types of POS’ Twitter-users draw urban patterns. The Origin-Destination patterns generated illustrate new social behaviours, addressed to multifunctional uses. This chapter aims to be influential in the use of UGC analysis for planning purposes and to increase quality of life.
Social Implications of New Mediated Spaces: The Need for a Rethought Design Approach
Authors: Zammit Antoine , Kenna Therese , Maksymiuk Gabriela 
Published: March 2019

AbstractDeparting from the traditional understanding of the social implications of urban design and the underlying notion of ‘place’, the chapter first questions its current relevance vis-à-vis the mediated city. It examines whether ICT has given rise to the establishment of new notions of space and place, identifying new design challenges for cities and rethought approaches to the production of space. In view of the latter, the chapter subsequently questions the manner with which digital media may facilitate inclusive design of public spaces. In order to address this objective, the chapter illustrates some interesting empirical data emanating from literature and research projects based in the UK, Poland and Malta. The case studies in the literature illustrate how ICTs are being used as tools within participatory processes for the inclusive design of urban public and recreational spaces and in order to gauge citizen/user expectations towards urban space. The chapter finally attempts to redefine public participation through ICT and to frame the above discussion within the potentially newly redefined role of urban designers involved in such processes. The underlying question to be addressed in this chapter, therefore, has to deal with the manner with which urban professionals may effectively achieve inclusive participatory design, particularly in light of new phenomena brought about by the mediated city and with the potential of this newly obtained and enriched data.
Using ICT in the Management of Public Open Space as a Commons
Authors: Artopoulos Georgios , Arvanitidis Paschalis , Suomalainen Sari 
Published: March 2019

AbstractThe chapter defines public open space as a commons and explores innovative ways for its management and sustainable development through the use of new information and communication technologies. It argues that hybrid conglomerates of space and technological interfaces provide this possibility. Section 2 defines common pool resources and discusses issues of its management, before it moves to identify public open space as a commons and to outline key directives for governance. Section 3 outlines the new ICT and considers practices and technologies that can be used in order to enhance community identity, social interaction and user engagement in the governance of the public open space as a commons. Finally, the last section concludes this chapter with some remarks on the conditions under which the hybrid of a public open space with ICT features could be approached as yet another kind of ‘soft’ type of common pool resource.
Heterotopic Landscapes: From GreenParks to Hybrid Territories
Authors: Patrício Catarina , Breser Christoph , Ioannidis Konstantinos 
Published: March 2019

AbstractThis chapter develops an interest in clarifying the meaning of cyberparks through an interrogation beyond its material preconditions. A cyberpark, as a fold in space generated by a hybrid emergent form of co-mediated space, is a disjunctive combination: it presupposes an encounter between open public urban places and the use of ICT tools. Outstretched beyond its physical manifestation as a place of encounter, a «heterotopic» reading might reveal that the subject is displaced in many different ways, from the analogue to the digital landscape, and from the specificity of the local to the universal of the global web. It is in such transferences that several worlds blend, both in its symbolic function and social significance. Impacts of such «Other Spaces» on the nature of human being’s behaviours can be critically reflected by the consideration of the social role of ICTs as tools of alienation through reinforced governances. Hence the question of creating «non-places» arouses, affording both a consensual appropriation process and the representative commodity networks, that henceforth includes natural, technical and human aspects and at the same time constitutes hybrid identities at the interfaces of its users, subjects, objects and places.
Modelling Co-creation Ecosystem for Public Open Spaces
Authors: Skarzauskiene Aelita , Maciuliene Monika , Ivanova-Radovanova Petja 
Published: March 2019

AbstractCo-creation can be defined as the involvement of citizens in the initiation and/or the design process of public services in order to (co)create beneficial outcomes and value for society. Mediated public open spaces are ideal environments for co-creation to emerge due to the involvement of the community and ICT in the knowledge creation. The aims of the research presented in the chapter are two-fold: to conduct a mapping activity in order to collect the insights on civic technologies promoting the creation of open public spaces through the use of ICT and to define the critical dimensions in designing co-creative ecosystems. The mapping strategy was conducted by evaluating the civic technologies in Lithuania and Bulgaria. The insights from the empirical exercise allow to draw managerial and organizational recommendations for strengthening the collective efforts of citizens, IT developers, public and governmental institutions in creating open, inclusive and reflective open public spaces.
Using ICTs for the Improvement of Public Open Spaces: The Opportunity Offered by CyberParks Digital Tools
Authors: Osaba Eneko , Pierdicca Roberto , Duarte Tiago , Bahillo Alfonso , Mateus Diogo 
Published: March 2019

AbstractIn the last decade, the potential of mobile devices for augmenting outdoor experience opened up new solutions, whose value is twofold. On one hand, users can experience new forms of interaction with space. On the other, stakeholders can have access to the so-called User Generated Data, that is different types of information related to public spaces that could be used to improve their conception of space. In line with this, several digital tools have been developed and tested within the framework of CyberParks COST Action TU-1306 with the intention of exploring how information and communication technologies (ICTs) can contribute to the improvement of Public Open Spaces (POS). In this way, this chapter aims to study the relationship between ICTs and POS, focused on the opportunities offered by three different digital tools: the WAY-CyberParks, the EthnoAlly, and the CyberCardeto. The main advantages of using these digital tools are: (1) the real-time data gathering, (2) maintaining an updated database, (3) collecting traces of different activities and users’ groups “at the same time and space”, and (4) recording their opinion and preferences, via text, video, sound or pictures. Furthermore, the chapter attempts to analyse distinct types of results produced by their use, based on different study cases where the digital tool has been tested. The data obtained in these places serve to demonstrate the features and type of data gathered. With these case studies, the chapter attempts to highlight the main potential of each platform as related to different stakeholders and users.
A Pedagogical Model for CyberParks
Authors: Bonanno Philip , Klichowski Michal , Lister Penelope 
Published: March 2019

AbstractThis chapter discusses the recent conceptual developments about CyberParks and their educational potential. Key learning characteristics and pedagogical principles will be identified through a review of learning theories and studies from cognitive neuroscience. Relevant pedagogical models are reviewed to develop one that describes learning in CyberParks, which will be used to design and evaluate learning in such context. An innovative connectivist-inspired process-oriented pedagogical model is proposed to serve as a signpost in the process of developing adaptive expertise through which new pedagogies and innovative uses of CyberParks address the evolving needs of citizens.
Teenagers’ Perception of Public Spaces and Their Practices in ICTs Uses
Authors: Menezes Marluci , Arvanitidis Paschalis , Smaniotto Costa Carlos , Weinstein Zvi 
Published: March 2019

AbstractThe new information and communications technologies are expanding human connectivity, reconfiguring urban spatialities and generating a kind of social space that spans real and virtual, personal and impersonal, private and public. As a result, the space and time boundaries become blurred, giving rise to novel needs for, and practices of, public space usage. However, the ways in which these new practices affect public space engagement and public life in general, remain yet unclear. In addition, variations might exist due to differences in local culture and conditions, or due to specific lifestyles and behaviours favouring isolation and privatism or, at best, interaction only with close friends and kin. The above issues become even more critical for young people, who born in a digital era are able to handle new technologies with utmost ease. This chapter sheds light on the related perceptions and practices of adolescents. Structured interviews were applied to eight teenagers living in Hannover (Germany), Lisbon (Portugal), Tel Aviv (Israel) and Volos (Greece) to gather focused, qualitative and textual data. It examines how young people of distinct sociocultural contexts perceive and use both public spaces and digital technologies. This enables to identify emergent logics, needs and patterns of socialization and public space engagement placing specific emphasis on the role information technologies can play in them.

Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) for Severe Torso Trauma in Japan: A Descriptive Study
Authors: Matsumoto Shokei , Hayashida Kei , Akashi Taku , Jung Kyoungwon , Sekine Kazuhiko , Funabiki Tomohiro , Moriya Takashi 
Published: March 2019

AbstractBackgroundResuscitative endovascular balloon occlusion of the aorta (REBOA) has the potential to be an alternative to open aortic cross‐clamping (ACC). However, its practical indication remains unknown. We examined the usage trend of REBOA and ACC in Japan for severe torso trauma and investigated whether these procedures were associated with the time of death distribution based on a large database from the Japan Trauma Data Bank (JTDB).MethodsThe JTDB from 2004 to 2014 was reviewed. Eligible patients were restricted to those with severe torso trauma, which was defined as an abbreviated injury scale score of ≥4. Patients were classified into groups according to the aortic occlusion procedures. The primary outcomes were the rates of REBOA and ACC use according to the clinical situation. We also evaluated whether the time of death distribution for the first 8 h differed based on these procedures.ResultsDuring the study period, a total of 21,533 patients met our inclusion criteria. Overall, REBOA was more commonly used than ACC for patients with severe torso trauma (2.8% vs 1.5%). However, ACC was more frequently used in cases of thoracic injury and cardiac arrest. Regarding the time of death distribution, the cumulative curve for death in REBOA cases was elevated much more slowly and mostly flat for the first 100 min.ConclusionsREBOA is more commonly used compared to ACC for patients with severe torso trauma in Japan. Moreover, it appears that REBOA influences the time of death distribution in the hyperacute phase.
The Effectiveness of Contralateral Drainage in Reducing Superficial Incisional Surgical Site Infection in Loop Ileostomy Closure: Prospective, Randomized Controlled Trial
Authors: Serracant Anna , Serra‐Aracil Xavier , Mora‐López Laura , Pallisera‐Lloveras Anna , Serra‐Pla Sheila , Zárate‐Pinedo Alba , Navarro‐Soto Salvador 
Published: March 2019

AbstractBackgroundLoop ileostomy reduces the rates of morbidity due to colorectal anastomotic dehiscence. For its part, ileostomy closure is associated with low mortality (0–4%) but substantial morbidity (11–37%). Incisional surgical site infection (SSI) is one of the most frequent complications (2–40%).MethodsA single‐center, prospective, randomized controlled clinical trial of two study groups: control (conventional primary skin closure) and experimental (primary skin closure with a contralateral Penrose® drain).ResultsSeventy patients undergoing loop ileostomy closure between April 2013 and June 2017 were included (35 per branch). Four were later removed from the study. Six of the remaining 66 patients (per protocol analysis) were diagnosed with incisional SSI (9.1%); there were no statistically significant differences between the two groups (control group: 9.7%; experimental group: 8.6%) or between the risk factors associated with incisional SSI. Rates of overall and relevant morbidity (Clavien ≥ III) were considerable (28.1% and 9.1%, respectively), and there were no statistically significant differences between the two groups. No patients died.ConclusionContralateral drainage does not significantly affect the results of primary ileostomy closure. The rate of incisional SSI was similar in the drainage and non‐drainage groups, and the overall rate of 9.1% was in the low range of those reported in the literature. The absence of mortality (0%) and the non‐negligible rates of overall and relevant morbidity (28.1% and 9.1%, respectively) in our series suggest that loop ileostomy is a safe procedure. However, the bowel reconstruction involves risks that must be borne in mind.Clinical trial registrationThe study was registered and approved by the clinical research ethics committee of the study center (reference number 2012076). Clinical trial was registered in ClinicalTrial.gov (identification number NCT02574702 and reference: ILEOS‐ISS_2013).
Batch-feeding whole-cell catalytic synthesis of α-arbutin by amylosucrase from Xanthomonas campestris
Authors: Zhu Linjiang , Jiang Dan , Zhou Yaoyao , Lu Yuele , Fan Yongxian , Chen Xiaolong 
Published: March 2019

Abstract
α-Arbutin is an effective skin-whitening cosmetic ingredient and can be synthesized through hydroquinone glycosylation. In this study, amylosucrase (Amy-1) from Xanthomonas campestris pv. campestris 8004 was newly identified as a sucrose-utilizing glycosylating hydroquinone enzyme. Its kinetic parameters showed a seven-time higher affinity to hydroquinone than maltose-utilizing α-glycosidase. The glycosylation of HQ can be quickly achieved with over 99% conversion when a high molar ratio of glycoside donor to acceptor (80:1) was used. A batch-feeding catalysis method was designed to eliminate HQ inhibition with high productivity (&gt; 36.4 mM h−1). Besides, to eliminate the serious inhibition caused by the accumulated hydroquinone oxidation products, the whole-cell catalysis was further proposed. 306 mM of α-arbutin was finally achieved with 95% molar conversion rate within 15 h. Hence, the batch-feeding whole-cell biocatalysis by Amy-1 is a promising technology for α-arbutin production with enhanced yield and molar conversion rate.
Is self-identity essential to objects?
Authors: Spinelli Nicola 
Published: March 2019

AbstractA common view is that self-identity is essential to objects if anything is. Itself a substantive metaphysical view, this is a position of some import in wider debates, particularly (but not exclusively) in connection with such problems as physicalism and personal identity. In this article I challenge the view. I distinguish between two accounts of essence, the modal and the definitional, and argue that self-identity is essential to objects on the former but not on the latter. After laying out my case, I deal with a number of objections.

Abstract
Introduction Minimally invasive surgery has revolutionized surgical management in the treatment of colorectal neoplasms, reducing morbidity and mortality, hospitalization, inactivity time and minimizing cost, as well as providing adequate oncological results when compared to the conventional approach. Robotic surgery, with Da Vinci Platform, emerges as a step ahead for its potentials. The objective of this article is to report the single institutional experience with the use of Da Vinci Platform in robotic colorectal surgeries performed at a reference center in oncological surgery in Brazil.
Materials and methods A retrospective cohort study was conducted based on the prospective database of patients from the institution submitted to robotic surgery for treatment of colorectal cancer from July 2012 to September 2017. Clinical and surgical variables were analyzed as predictors of morbidity and mortality.
Results A total of 117 patients underwent robotic surgery. The complications related to surgery occurred in 33 patients (28%), the most frequent being anastomotic fistula and surgical wound infection, which corresponded to 11% and 3%, respectively. Conversion rate was 1.7%. Median length of stay was 5 days. The only variable associated with increase of complications and death risk was BMI >30, with p-value of 0.038 and 0.027, respectively.
Conclusion Robotic surgery is safe and feasible for approaching colorectal cancer surgeries, presenting satisfactory results regarding length of hospital stay and rate of operative complications, as well as presenting a low rate of conversion. Obesity has been shown to be a risk factor for surgical complication in robotic colorectal surgery.
Is job insecurity always bad? The moderating role of job embeddedness in the relationship between job insecurity and job performance
Authors: Qian Shanshan , Yuan Qinghong , Niu Wanjie , Liu Zhaoyan 
Published: March 2019

AbstractConsidering the mixed results of the relationship between job insecurity and job performance, this study investigated the interaction effect of job insecurity and job embeddedness on job performance and examined the mediating role of affective commitment from the perspectives of conservation of resources theory and social exchange theory. A survey of 725 contract employees from two Chinese private manufacturing companies revealed that when employees had high levels of job embeddedness, job insecurity was significantly and positively related to job performance. In contrast, job insecurity was significantly and negatively related to job performance when there were low levels of job embeddedness. Furthermore, the results indicated that affective commitment mediated the interaction effect. The above conclusions not only illustrate the important role of job embeddedness in the relationship between job insecurity and job performance but also provide beneficial ideas and information to organisations and employees for managing job insecurity.
A CONVERSE THEOREM FOR BORCHERDS PRODUCTS ON
Authors: BRUINIER JAN HENDRIK , SCHWAGENSCHEIDT MARKUS 
Published: March 2019

We show that every Fricke-invariant meromorphic modular form for $\unicode[STIX]{x1D6E4}_{0}(N)$ whose divisor on $X_{0}(N)$ is defined over $\mathbb{Q}$ and supported on Heegner divisors and the cusps is a generalized Borcherds product associated to a harmonic Maass form of weight $1/2$. Further, we derive a criterion for the finiteness of the multiplier systems of generalized Borcherds products in terms of the vanishing of the central derivatives of $L$-functions of certain weight $2$ newforms. We also prove similar results for twisted Borcherds products.
