Coworking Spaces and the Transcendence of Social Innovation Knowledge in the Smart Territory
Authors: Larios-Hernandez Guillermo J. , Borbolla-Albores Alberto
Published: January 2021

Smart territories favor social entrepreneurship, which develops in a collaborative effort requiring networking and skilled facilitation. Coworking spaces (CWS) advance as mediating organizations that bring together entrepreneurial communities in smart territories. This chapter develops a practical framework for knowledge dissemination in CWS. It bases this framework on the analysis of three spatial characteristics that allow for the assessment of the knowledge transcendence originating in CWS, namely, physical, social, and informational spaces. To test this framework, the authors analyze the Roma-Norte corridor in Mexico City, whose results indicate the presence of two models: one constituted of private organizations that place collaboration as a secondary value, subject to their office rental services, and an umbrella model that clusters other social innovation facilitators that transcend their territorial strip. This latter meta-space model expresses positive effects in terms of knowledge spillover, suggesting the concentrated bottom-up construction process of a smart territory.

The Significance of Trust to the Adoption of E-Working Practices Within Local Government
Authors: Beadle Hazel
Published: January 2021

Drawing upon an in-depth study of one local authority based in the United Kingdom, this article examines the significance of trust to local government workers who are beginning to make increasing use of e-technologies through e-working practices. The article identifies trust to be of particular significance but that the examined context is not supportive of that trust being developed. It notes differences in the perceptions surrounding trust development, that consideration of trust is not just limited to the relationship between management and their workers, and that there is a fear that trust is at risk of abuse. In the face of e-work serving to raise the profile of trust as a significant factor for concern, the associated technologies are suggested to have the potential to offer a solution to some of the issues arising.
Enterprise Systems, Power and Improvisation
Authors: Wainwright David W. , Waring Teresa S.
Published: January 2021

Enterprise systems (ES) have been extensively procured in large organizations but much research fails to develop sociotechnically informed approaches that facilitate their implementation whilst understanding the impact of integrated technology on professional working practices within complex organizational environments. This chapter takes a critically informed sociotechnical approach to power and improvisation in ES implementation. The contribution is a combined “circuits of power-improvisation” (CPI) framework which can facilitate a better understanding of ES implementation, sociotechnical theory, and practice. Practical lessons learned from the study may potentially be used to avoid some of the problems experienced with the over-zealous and rapid introduction of digital technologies into university organizations where the risk is that they become a student mass production system. It highlights the important role of power and improvisation, enabled and afforded by new digital technologies, in what may be misrepresented as planned strategic and deliberate organizational change.
Continuous Improvement Maturity Models
Authors: Galli Brian J.
Published: January 2021

Maturity models seek to enhance a business with the passage of time. The purpose is to attain a competitive advantage. Various maturity models are accessible, including the continuous improvement maturity model (CIMM). The model offers outstanding techniques and practice models in addition to tools, skill sets, and a proper mindset to process improvement. This article analyzes the need for Continuous Improvement Maturity Models in a company. Hence, the current maturity of a company cannot be indicated by this model. There is a need for progress and knowledge to combine and improve the company's level of maturity. The model assessment refers to an instrument that is research-based and assists the users to set a goal assessment of the maturity level. The purpose of designing this model is for it to be utilized by any manufacturing company. A series of repetitive phases are required by this instrument, and its moderations and validation are based on various case-studies and semi-structured interviews conducted with experts.

Exploring the Impact of Flexible and Permeable Work-Life Boundaries in a Mobile World
Authors: McCloskey Donna Weaver
Published: January 2021

Work-life boundaries are often studied on a segmentation-integration continuum, which fails to consider that boundaries can be multidimensional. A flexible boundary allows work to be completed at different times and locations, whereas a permeable boundary allows for the integration of work and personal demands. This chapter examines boundary flexibility, home boundary permeability, and work boundary permeability as separate constructs, positing eight possible boundary configurations. In this exploratory research, differences in demographics, technology usage, work-family conflict, and work and life satisfaction for 65 knowledge workers who maintain different levels of boundary flexibility and permeability are examined. This research offers a new boundary configuration framework, which should guide future research and organizational policy.

Education, Community, and Social Engagement
Authors: Jenkins Toby S.
Published: January 2021

In many higher education and student affairs graduate programs the responsibility for providing field-based learning often falls on the graduate assistantship. Programs often situate theoretical learning inside the classroom and practical engagement at the assistantship site. The growing urgency for educators to create transformative learning experiences and to integrate deep interactions with issues of social justice into the classroom challenges graduate faculty to re-evaluate their approach to teaching and learning. In this chapter, the author makes the case for adopting a creative, community-based, and culturally engaging approach to teaching in graduate education programs.
The ‘New Paradigm' of the Sociology of Childhood
Authors: Ba' Stefano
Published: January 2021

This chapter aims at developing a critique of the so-called “New Paradigm” of the sociology of childhood, which was developed in British sociological schools between the 1960s and 1980s. The New Paradigm represented a substantial challenge to mainstream sociology of childhood and from this basis, Childhood Studies were capable of producing influential thinking about childhood and practices involving childhood. The main idea of this chapter is that the New Paradigm cannot constitute an adequate theoretical basis for ensuring the fulfilment of children's lives in terms of freedom and social justice. Its central point, that childhood is socially constructed, is not articulated coherently and is internally inconsistent. Italian alternative pedagogical practices are used to provide a concrete backdrop for the theoretical objections raised against the New Paradigm. These alternative critical practices commonly assert that theory cannot be separated from practice and that ideals of social justice for children are based on the struggles of marginalised communities.

Deployment of Narrowband Internet of Things
Authors: Routray Sudhir K.
Published: January 2021

Internet of things (IoT) is an integral part of modern digital ecosystem. It is available in different forms. Narrowband IoT (NBIoT) is one of the special forms of the IoTs available for deployment. It is popular due to its low power wide area (LPWA) characteristics. For new initiatives such as smart grids and smart cities, a large number of sensors will be deployed and the demand for power is expected to be high for such IoT deployments. NBIoT has the potential to reduce the power and bandwidth required for large IoT projects. In this chapter, different practical aspects of NBIoT deployment have been addressed. The LPWA features of NBIoT can be realized effectively if and only if its deployment is done properly. Due to its large demand, it has been standardized in a very short span of time. However, the 5G deployment of NBIoT will have some new provisions.

Authors: Tal Irina , Muntean Gabriel-Miro
Published: January 2021

This chapter highlights the importance of vehicular ad-hoc networks (VANETs) in the context of the 5G-enabled smarter cities and roads, a topic that attracts significant interest. In order for VANETs and its associated applications to become a reality, a very promising avenue is to bring together multiple wireless technologies in the architectural design. 5G is envisioned to have a heterogeneous network architecture. Clustering is employed in designing optimal VANET architectures that successfully use different technologies. Therefore, clustering has the potential to play an important role in the 5G-VANET-enabled solutions. This chapter presents a survey of clustering approaches in the VANET research area. The survey provides a general classification of the clustering algorithms, presents some of the most advanced and latest algorithms in VANETs, and it is among the fewest works in the literature that reviews the performance assessment of clustering algorithms.
Improving Climate Change Resilience in Global South Cities Through South-South Climate Finance
Authors: Chirambo Dumisani
Published: January 2021

Climate change is likely to exacerbate inequality and poverty in Global South cities despite the presence of international agreements and conventions to enhance sustainable development such as the Paris Agreement and the Sustainable Development Goals (SDGs). Moreover, replicating Global North development models in the Global South might not be sufficient to address the climate change and development aspirations in the context of Asia; hence, Global North innovation capabilities might not be sufficient to address Global South climate change challenges. This paper provides an inductive analysis of the innovations and policies that could facilitate improved climate change mitigation and adaptation in the context of developing Asian cities. The paper concludes that innovative climate change policies should utilise emerging climate finance mechanisms such as South-South climate finance modalities to promote community science/citizen science and social innovation rather than building hard infrastructure as this could improve the governance and distribution of resources in cities.
Innovation to Harness Youth Entrepreneurial Potential
Authors: Baporikar Neeta
Published: January 2021

Youth face challenges like unemployment, poverty, career gloom, poor mentorship, resources shortage, including access to facilities and information. A small percentage of the millions of high school graduates continue with tertiary education. The untested and tried millions of youth possess potent innovation and creativity that could contribute to socio-economic transformation in general and more so for the transition of Southern African states. Some of these youth join the labor market and others become entrepreneurs for survival but lack skills, creativity, and innovation. Here the circular economy presents opportunities and gives a chance to exploit their innovation and creativity potential. Adopting an exploratory method and data collection from the extensive literature review, interviewing experts, and personal experience, the objective of this study is to deliberate how innovation can harness youth entrepreneurial potential for much needed social and economic development. Stakeholders' feedback and insights sync with the literature on circular economy and inclusive innovation.
Integration Challenges of Immigrants in Smart Cities
Authors: Bernardino Susana , Santos J. Freitas
Published: January 2021

The most recent interpretations of the concept of smart city (SC) highlight the need for adopting a more holistic vision of SC, which includes other relevant features for understanding the dynamism of urban development and face new challenges. The study of a social entrepreneurship initiative (SPEAK) that aims to empower immigrants living in the main Portuguese cities is the method used in this research to understand the extent to which social innovation can make smart cities more human and sustainable. The results illustrate how a social entrepreneurship initiative can positively impact the creation of social value to immigrants in cities. As the evidence shows, the full integration of foreign migrants in cities may contribute to the sustainable resolution (or avoidance) of many severe social dysfunctions, as well as for the improvement of the quality of life of foreign migrants and local citizens. The approach adopted, based on the empowerment of the human element, is able to produce a sustainable response and contribute to other dimensions of SC.
Agency vs. Stewardship Theory in Local Government Contracted Mobile Apps
Authors: Perlman Bruce J. , Reddick Christopher G. , Zheng Yueping
Published: January 2021

This paper examines citizen satisfaction levels with local government contracted mobile platforms and applies two theories of the contracting relationship to them: principal-agent and stewardship theory. It uses survey data to compare citizen satisfaction factors for mobile phone applications (apps) contracted by Chinese local governments. It looks at contracting out, a key element of privatization, from a unique perspective. Most research on government contracting focuses on cost and quality in service delivery. This research looks at citizen satisfaction with contracted mobile platforms. Ordered logistic regression analysis is used on data from a user survey of local government contracted mobile apps in 30 cities in China. The study found that the strongest predictors of contracted mobile apps satisfaction were usability, overall app satisfaction, and trust, supporting the stewardship theory. The results challenge existing research showing that citizen satisfaction is influenced more by openness and trust than by cost, at least in mobile apps.

Cutting Behavior of Self-Lubricating Ceramic Tool in Dry Machining of 40Cr Quenched Steel
Authors: Wang Ben Yuan , Xiao Guang Chun , Chen Zhao Qiang , Yi Ming Dong , Zhang Jing Jie , Xu Chong Hai
Published: January 2021

In this paper, the dry cutting performance of Al2O3/TiC-based ceramic composites with nanoCaF2 was studied. Compared with the Al2O3/TiC ceramic tool, the Al2O3/TiC/CaF2 ceramic tool has lower cutting force, cutting temperature and surface roughness when milling 40Cr hardened steel. Three cutting parameters of cutting speed, feed per tooth, and cutting depth were used to conduct orthogonal experiments to study its changing trend. Through testing of cutting force, cutting temperature and surface roughness, and by comparison with ceramic tools without nanosolid lubricant added, the order of influence of three cutting parameters on cutting force, cutting temperature and surface roughness was obtained. The experimental results showed that the cutting force, cutting temperature and surface roughness of Al2O3/TiC/CaF2 ceramic tools containing nanoCaF2 werebetter than those of Al2O3/TiC ceramic tools. The cutting force, the cutting temperature, and the surface roughness were respectively reduced by 16.5%, 25.8% and 43% compared to when no solid lubricant was added. In addition, after adding solid lubricant, the effect of cutting depth on cutting force was significantly reduced. The average friction coefficient of the tool rake surface was 31.1% lower than that of ceramic tools without solid lubricant. In order to explain this phenomenon, through scanning electron microscopy (SEM) scanning and energy spectroscopy (EDS) elemental analysis, the wear reduction mechanism of solid lubricants was analyzed, that is, during the cutting process, nanosolid lubricants precipitated and formed lubricating film on the rake surface of the tool to reduce the friction coefficient. This was also the main reason for reducing the cutting temperature.
Influence of Mould Slenderness Ratio on the Solidification of Heavy Ingots by Numerical Simulation
Authors: Zhao Ya Nan
Published: January 2021

The quality of heavy ingot normally depends on the processing factor and ingot mould type. Based on the ingot mould type only, the quality and solidification process of a 96-ton ingot moulds with different slenderness-ratios have been studied numerically using the software package ProCAST. The results show that the position of shrinkage porosity moves up and the macroporosity in the ingot center increases prominently as slenderness-ratio increasing, meanwhile, the inclusion-floating time through the middle and bottom part of ingot decreases, and A-segregation alleviates as well. The correlation between the quality and slenderness-ratio of the ingot is not a liner relationship, when the slenderness ratio is 1.4, the ingot has better quality.
Research on the Stability of Pd-Based Multi-Component Supported Catalysts
Authors: Zhang Yong Li
Published: January 2021

Based on SEM, FT-IR and XRD characterization, the catalyst Pd-Fe-Co-Ce/FSC (ratio 1:1:1:3) was calcined at a temperature of 550°C and a calcination time of 3 h. The catalyst is applied to the catalytic wet oxidation treatment of difficult-to-biodegradable organic waste-water. By the characterization of the catalyst before and after the reuse, it is verified that the SEM morphologis of the catalyst changed little, and the groups contained in the catalyst characterized by FT-IR hardly changed, and the XRD characteristic peaks did not change. From the SEM photos of the catalyst before and after use, the morphology of the catalyst does not change much, and the agglomerated support on the catalyst surface is slightly reduced; the absorption peaks of the FI-IR spectrum of the catalyst before and after use are not significantly different, indicating that the functional groups contained in the catalyst have not changed significantly; After using the catalyst, compared with before use, the characteristic peak shape of each characteristic diffraction did not change significantly. The results show that the catalyst Pd-Fe-Co-Ce/FSC (ratio 1:1:1:3) revealed a stable catalyst performance in the process of CWAO for the treatment of difficult-to-biodegradable organic waste-water.

Then the nanoindentation and 3DAP tests were carried out to study the hardening and radiation induced segregation (RIS) behaviors of the reactor internals stainless steel specimens irradiated with 6 MeV Xe ions at room temperature. It is indicated that higher irradiation damage will cause more significant hardening and RIS and consequently increase the IASCC susceptibility.
Anesthesia for GI endoscopy in the era of COVID-19
Authors: Goudra Basavana , Singh Preet Mohinder
Published: January 2021

As a result of COVID-19, the last few weeks have necessitated a reevaluation of the sedation paradigm for gastrointestinal (GI) endoscopic procedures. Routine screening and some surveillance procedures have taken a backseat and likely to remain so until a vaccine or effective treatment becomes available. Anesthesia providers and endoscopists are required to adapt to this new reality rapidly. The general aim of sedation remains the same-patient comfort, reduced hypoxia, prevention of aspiration along with rapid recovery, and discharge. The present review focuses on necessary modification to reduce the risk of virus contagion for both patients (from health-care providers) and vice versa. A preprocedure evaluation and consenting should be modified and provided remotely. Unsedated GI endoscopy, sedation with minimal respiratory depression, and modification of general anesthesia are explored. Challenges with supplemental oxygen administration and monitoring are addressed. Guidelines for appropriate use of personal protective equipment are discussed. Measures for limiting aerosolization are deliberated.

War crimes in cyberspace: prosecuting disruptive cyber operations under Article 8 of the Rome Statute
Authors: Beatty Georgia
Published: January 2021

This article reviews the existing scholarship concerning the applicability of IHL norms to cyberspace, and in particular the Tallinn Manual, which is considered to be the most authoritative restatement of international law applicable in the cyber context. In doing so, it seeks to answer the question of whether purely disruptive (as opposed to physically destructive) cyber operations could be prosecuted as war crimes at the International Criminal Court under Article 8 of the Rome Statute. The Tallinn Manual, being a restatement of lex lata at the time that it was drafted, places a heavy emphasis on physical effects when applying the jus in bello to cyber warfare. If the ICC were to rely on the Tallinn Manual’s conclusions to inform its interpretation of Article 8 in relation to cyber-based war crimes, this could have the effect of excluding disruptive cyber operations from its jurisdiction. This is a cause for concern in a world where militaries and civilian populations alike are becoming increasingly reliant on computer systems and the internet. Disruptive cyber operations can result in devastating consequences even though they do not cause physical damage, and are likely to become more powerful and sophisticated in future as technology develops.

Sektor usaha kecil atau Usaha Mikro, Kecil, dan Menengah (UMKM) terbukti telah mendorong dan merangsang pertumbuhan ekonomi nasional secara berkesinambungan. Data Kementerian Koperasi dan Usaha Kecil Menengah (Kemenkop dan UKM) menunjukkan bahwa 97% lapangan kerja diberikan oleh UMKM sehingga berkontribusi signifikan mengurangi pengangguran di Indonesia. Melihat peran penting tersebut, maka dibutuhkan dukungan dari seluruh pihak untuk mengembangkan dan mewujudkan UMKM yang maju, mandiri, dan modern.
Salah satu alat yang digunakan untuk mengukur kemajuan aktifititas usaha pada UMKM adalah melihat pertumbuhan laba pada laporan keuangannya. Namun, dalam aktivitasnya mayoritas UMKM (termasuk UMKM di kelurahan Meruya Selatan) belum memiliki pengurus yang cakap dalam bidang keuangan dan  akuntansi. Sehingga, permasalahan yang dihadapi oleh mitra adalah tata kelola manajemen usaha masyarakat baik dari segi manajemen administrasi, pembukuan dan akuntansi. Dengan demikian, kami dari Universitas Mercu Buana Jakarta,  mengadakan kegiatan Pengabdian Masyarakat di keluarahan Meruya Selatan khususnya usaha masyarakat yang dikelola uleh RPTRA Manunggal dengan tujuan untuk membantu pengurus UMKM agar transaksi keuangan mereka tertata dengan baik, tepat waktu, efektif dan efisien.
Materi yang disampaikan pada kegiatan pelatihan ini, meliputi: Pembahasan tentang manfaat akuntansi, akuntansi pada sektor usaha kecil sesuai dengan SAK-EMKM, bagaimana melakukan pencatatan dan pembukuan transaksi keuangan sampai pada pembuatan laporan keuangan sesuai standar akuntansi sektor usaha kecil (SAK-EMKM).  Dengan demikian harapan pengabdian kepada masyarakat ini dapat ikut berpartisipasi memberdayakan peningkatan ketrampilan masyarakat dalam memahami Akuntansi UMKM.
Metode yang digunakan adalah metode ceramah, tanya jawab, metode simulasi dan praktek. Kegiatan ini memperoleh tanggapan positif dari para peserta, khususnya para pemilik UMKM. Dalam pelaksanaan kegiatan pengabdian masyarakat ini menunjukkan, bahwa peserta dapat mengenal dan mempraktekkan membuat pencatatan dan transaksi yang terjadi sehari-hari pada usaha mereka. Hasil yang di capai dari pelatihan ini 70% para peserta sudah bisa menyusun laporan keuangan dangan baik. Sedangkan 30% dari peserta masih mengalami kendala dalam menyusun laporan keuangan karena masih kesulitan dalam menentukan mana akun yang akan dimasukkan kedalam laporan laba rugi, laporan perubahan ekuitas, neraca dan laporan arus kas
