Digital and Collaborative Work
Authors: Lison Christelle , Denis Constance
Published: January 2021

Do digital and collaborative work go hand in hand? This chapter combines the practical experience of two university teachers and literature to answer this question. Basic notions are revisited: Collaborative work, Distance learning, Social constructivism, Authentic learning to establish the winning conditions. Collaborative work implies three types of action, i.e. communicating, coordinating, and producing. Digital technology finds its place in each of these, given the great diversity of tools available. To promote collaborative work with digital, the authors propose to clarify teaching objectives, to vary digital and pedagogical tools, and to develop the evaluation of collaborative work. The practical experience helps to clarify the main constraints of remote collaborative work and to identify some key elements to be aware of. Several concrete examples illustrate the problems and possible solutions.

Authors: Janssens Jürgen
Published: January 2021

Companies are either international by nature, either their workforce is, or business dynamics and agile optimization create an extended web making it international. This obliges managers to gear up for the needs of this evolving DNA. This is especially the case in strategy critical project portfolio contexts focusing on organizational change, process transformation, or roll-out of headquarter-driven products/services. This chapter will address the required hard and soft assets: integrating the cultural essence and maturity of the ecosystem, combining experience with a pragmatic approach, and being dedicated to continuous shaping of collaborations. Additional focus will be set on managing in the digital age. To give more depth to the tangible value, different real-life cases will be integrated. Together, the theoretical insights and the empirical examples will offer a big picture view that will benefit the management of hybrid portfolios in geographically blended environments.

Authors: Zhao Fan , Kirche Elias T.
Published: January 2021

This article contends that vendors are now pushing into the small to mid-size organizational markets with simplified, less-risk, less-reward systems while consultants have project experience and have thorough contracts isolating their role. However, SMEs that adopted ERP on-premise solutions before are now facing a dilemma: continuing with ERP on-premise upgrades or switch to on-demand solutions. This article contains data surveyed from Chief Information Officers (CIO) of SMEs with respect to indicators of ERP adoptions. Cost, reduced demand for own IT resources, outage/accessibility and performance were found to be the most critical and important factors to assess ERP adoptions for SMEs.

Understanding the Effect of Digital Literacy on Employees' Digital Workplace Continuance Intentions and Individual Performance
Authors: Marsh Elizabeth
Published: January 2021

While a growing body of literature suggests that employees' digital skills are important to enable both individuals and organisations to make the most of the digital workplace, empirical understanding of their effect on technology adoption and performance is currently limited. Drawing on prior models of technology acceptance and continuance, the present study investigated the effect of digital literacy on behavioural intention to continue using the digital workplace and, ultimately, on individual performance. Linear regression was used to analyse the conceptual model using survey data from 142 employees of a major UK charitable organisation. Results partially supported the model, demonstrating that employees' digital skills effect continuance intentions and individual performance via their perceptions of ease of use. The findings suggest an important role for digital literacy, both as an antecedent to the more general determinants of technology adoption, and in organisational interventions designed to encourage digital workplace adoption.

Published: January 2021

In recent years we have witnessed a major transformation in society. We went from a society based on industry and transport to another based on information and knowledge. A major challenge for managers is to understand what the information is for formulation, definition, implementation, and control the strategy. The strategy for any organization can be set from the outside in. According to the schools of positioning, the offer of products will have to adapt to changes in the environment. Or from the inside out. According to the movement's schools, the organization influences the middle engaging with your innovative product offerings, since it has skills and capabilities that competitors don't have and that are difficult to imitate or buy. This chapter explores information and business strategies.

Theorizing Young People's Perceptions of Their Citizenship Identity
Authors: Leighton Ralph , Nielsen Laila
Published: January 2021

The paradigm of social justice gives voice to those without the resources to deal with responsibilities imposed by a neoliberal agenda. The authors focus on pupils in Sweden and England, countries which have moved from a sense of communality to the growth of neoliberal societal individualism. To clarify real citizenship (rather than formal), they apply the concepts of intersectionality and of human capabilities in place of rights, which means that people adhere to numerous simultaneous collectivities and having the capability to do something requires more than an entitlement to it. While everyone might have the right to an education and to a dignified life, many live in powerlessness and in political, social, and economic exclusion. Sufficient human capabilities are required in order to receive the education necessary for citizenship in its real meaning, and the intersectional approach enables interrogation of factors that coalesce, rather than viewing in them in isolation.
Myth Busting
Authors: Bussert-Webb Kathy , Díaz María E.
Published: January 2021

This longitudinal qualitative study, involving low-income parents and children, tutorial-agency staff, and one college student (all Latinx), took place in a city along the U.S./Mexico border. Data sources included field notes through participant observation, questionnaires, and interviews. The authors asked, “How are parents involved in their children's education? What limitations or barriers do they express?” Using a social justice framework and grounded-theory data analysis, these types of parental involvement emerged: academic, social skills, school volunteerism, extracurricular activities, community, and college enrollment. Conversely, parents expressed involvement obstacles. Implications relate to changing the deficit discourse regarding low-income, immigrant parents' involvement. Collaborating with families to create equitable educational outcomes for minoritized children is imperative.

The teachers' narratives describe their beliefs regarding academic ability grouping of students and the associated achievement gap that is often a result of this stratifying structure. Findings from the narratives reiterate the importance of teacher awareness regarding the impact of critical pedagogy as a fundamental element of teaching for social justice. The chapter indicates the usefulness of teacher narrative to influence alternative methods for course placement and schedule design in the high school curriculum.
Addressing Critical Multiculturalism in Online Education Using a Poly-Framework Approach
Authors: Banerjee Srikanta , Firtell Jill A.
Published: January 2021

Given the increasing number of available e-learning platforms, individuals are now able to pursue degrees and courses through an online modality. As a result, education has proliferated to include individuals from varying cultural groups, age distributions, and occupational qualifications. With the inclusion of a wide variety of groups, multicultural considerations are critical. However, from a multiculturalist and poststructaralist perspective, conventional models of multiculturalism are considered essentialist and often fastened by tradition rather than dynamic and continuously evolving practices. In this paper, the authors will apply multiculturalism to online education; present a critical perspective; and finally demonstrate a novel, dynamic and adaptable model that uses a poststructuralist viewpoint in order to meet the multicultural needs of the online student of today and possibly tomorrow. This model is derived from the key strengths of the Social Ecological Model, Hofstede's cultural dimensions theory, and Kolb's learning styles.

Conclusions summarize the significance of restorative practices in school settings in order to prevent violence, reduce rates of expulsions and suspensions, and create a safe and secure teaching and learning environment for all.
Family Literacy and Social Justice
Authors: Collier-Stewart Shartriya
Published: January 2021

The new Common Core State Standards are shifting education in a powerful way. Specifically, they are now tasking university teacher educators, K-12 administrators, and teachers to equip students with lifelong literacy skills. Students must learn skills such as how to develop effective argumentation and analyze and interpret complex texts. While such tasks can be quite daunting for the average monolingual speaker, they are even more challenging for children and families who do not speak English as a first language. This chapter examines the development of an eight-week intergenerational family literacy program: Teaching the Acquisition of Language Through English and Storytelling (T.A.L.E.S.). Through the use of the arts and storytelling, families were able to cultivate their bilingual voices and celebrate their multicultural identities. This chapter explores how such programs may be used as a vehicle for social justice, designed to integrate a community literacy model in which all stakeholders are accountable.

Authors: Blanch Joan Pagès , González Carolina García , Giraldo Martha Cecilia Gutiérrez
Published: January 2021

The chapter shows the situation of education for democratic citizenship in Latin America and its evolution over the last 25 years, taking as an example three countries: Chile, Colombia, and Mexico. First, the concept of citizenship in curricula is analyzed. Its role in the political and social re-democratization and its limitations are proposed as a result of a national identity concept that limits cultural, social, and political diversity. Their strengths and weaknesses are compared, considering issues like human rights, citizenship responsibilities, citizen participation, community boundaries, levels of identity, and cultural diversity. Second, the purposes of their teaching are interpreted in the curricula. It presents a curriculum focused on relevant social problems and on the formation of critical thinking and social participation and citizenship awareness. Finally, it reflects on the results of the international study on civic and citizen education in Latin America, pointing out its contradictions and the need to continue deepening in research and in teaching practice and training.
Exploring the Impact of Service-Learning on Literacy Teachers' Self-Reported Empathy
Authors: Saal Leah Katherine
Published: January 2021

Although (1) literacy teacher education research and professional practice standards highlight the significance of empathy as a central tenant of teachers' professional dispositions, and (2) developing deeper and more empathetic understanding of others is a frequently cited rationale for utilizing service-learning as a critical pedagogy for in-service and pre-service teacher preparation, little quantitative research exists measuring in-service teachers' empathy or empathy development. The purpose of this chapter is to explore how a course-embedded, self-selected, and community-based service-learning experience effected participating literacy teachers' self-reported empathy. While participants scores increased in the pre-post condition, results of a paired sample t-test indicated no significant difference in teachers' self-reported empathy across the pre-post condition. Implications for practice and program administration as well as suggestions for future research are discussed.

In particular, this chapter will present the views and experiences of two African American females, one being a new department chair at a small liberal arts college and the other being a new community college dean, committed to social justice and servant leadership. Using critical race theory, Black feminist perspectives, and intersectionality, the authors seek to document their investigation of society and culture through the sharing of their own lived experiences. Through their auto-ethnographies, the authors also answer the call to discuss how racial and gendered identities inform leadership development in order to challenge hegemonic discourses in higher education leadership.
Spectral Efficiency Self-Optimization through Dynamic User Clustering and Beam Steering
Authors: Parwez Md Salik , Farooq Hasan , Imran Ali , Refai Hazem
Published: January 2021

This paper presents a novel scheme for spectral efficiency (SE) optimization through clustering of users. By clustering users with respect to their geographical concentration we propose a solution for dynamic steering of antenna beam, i.e., antenna azimuth and tilt optimization with respect to the most focal point in a cell that would maximize overall SE in the system. The proposed framework thus introduces the notion of elastic cells that can be potential component of 5G networks. The proposed scheme decomposes large-scale system-wide optimization problem into small-scale local sub-problems and thus provides a low complexity solution for dynamic system wide optimization. Every sub-problem involves clustering of users to determine focal point of the cell for given user distribution in time and space, and determining new values of azimuth and tilt that would optimize the overall system SE performance. To this end, we propose three user clustering algorithms to transform a given user distribution into the focal points that can be used in optimization; the first is based on received signal to interference ratio (SIR) at the user; the second is based on received signal level (RSL) at the user; the third and final one is based on relative distances of users from the base stations. We also formulate and solve an optimization problem to determine optimal radii of clusters. The performances of proposed algorithms are evaluated through system level simulations. Performance comparison against benchmark where no elastic cell deployed, shows that a gain in spectral efficiency of up to 25% is possible depending upon user distribution in a cell.

Authors: Kitanov Stojan , Popovski Borislav , Janevski Toni
Published: January 2021

Because of the increased computing and intelligent networking demands in 5G network, cloud computing alone encounters too many limitations, such as requirements for reduced latency, high mobility, high scalability, and real-time execution. A new paradigm called fog computing has emerged to resolve these issues. Fog computing distributes computing, data processing, and networking services to the edge of the network, closer to end users. Fog applied in 5G significantly improves network performance in terms of spectral and energy efficiency, enable direct device-to-device wireless communications, and support the growing trend of network function virtualization and separation of network control intelligence from radio network hardware. This chapter evaluates the quality of cloud and fog computing services in 5G network, and proposes five algorithms for an optimal selection of 5G RAN according to the service requirements. The results demonstrate that fog computing is a suitable technology solution for 5G networks.

D2D- and DTN-Based Efficient Data Offloading Techniques for 5G Networks
Authors: Panigrahi Bighnaraj , Rath Hemant Kumar , Jagyasi Bhushan , Simha Anantha
Published: January 2021

With the advancement of smart phone technologies cellular communication has come to a stage where user bandwidth has surpassed the available bandwidth. In addition, the well-organized but stubborn architecture of cellular networks sometimes creates hindrance to the optimal usage of the network resources. Due to this, a User Equipment (UE) experiencing a poor channel to the Base Station (BTS) or evolved NodeB (eNB) or any other Access Point (AP) retransmits the data. In such scenarios, Device-to-Device (D2D) communication and offload/relay underlying the cellular networks or the access networks provides a unique solution where the affected UE can find a close proximity offloader UE to relay its data to eNB. Delay Tolerant Networks (DTN) is another framework which has potential usage in low-connectivity zones like cell edge and/or remote locations in cellular networks. This chapter investigates various possibilities where D2D and DTN can be jointly used to improve teledensity as well delayed but guaranteed services to poor or no connectivity areas.

Existing mobility protocols suffer from multimedia and data transfer disruption when crossing cities' boundaries by trains or cars. Session continuity in wide area motion is an officially raised goal by 5G-PPP vision. This research adopts 5G methodology by using software defined networking to propose a new mobile IP framework that facilitates seamless handover and ensures session continuity in standard and wide area coverage. The same uninterruptible experience is used to extend smart indoor services with effective offload mechanism to avoid core network congestion. Performance excels existing protocols in setup and handover delays as of eliminating 4G LTE bearer setup/release out-band signaling and isolating user's packets in OpenFlow virtual path that is recursively established in-line with IP address allocation. Handover cross cities in wide area motion becomes feasible with lower latency than LTE handover inside city. Throughput is instantly restored after handover while standard packets are wire speed forwarded as of tunnel headers' elimination and OpenFlow hardware abstraction.

Published: January 2021

This study aims to investigate the influences of rare earth element cerium (Ce) on microstructure and mechanical properties of low alloy ultra-high strength steel. The strength, plasticity, and impact toughness of steels with 0.0367% Ce and without Ce were tested. The influence mechanism of Ce on the microstructure and mechanical properties were investigated by scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS) and electron back scattered diffraction (EBSD). The results showed that the addition of Ce improved the comprehensive mechanical properties of low alloy ultra-high strength steel. In particular, the plasticity and toughness were improved obviously. The addition of Ce increased the elongation from 9.47% to 10.49%, and the low-temperature impact energy from 50J to 58J. The elongation and impact energy increased by 10.77% and 16%, respectively. And the yield strength of all samples remained above 1400 MPa. The rare earth element Ce did not change the matrix composition phase which were martensite. However, the addition of Ce increased the proportion of high-angle grain boundary from 33.2% to 40.2%. In addition, the Ce make the inclusions denatured and hence spherical inclusion with small size can be obtained. The EDS results showed that rare earth and harmful elements P and O formed inclusions, which as a purifier for the molten steel and hindered the formation of the large-size composite inclusions.

A 2020 View of Thymus Stromal Cells in T Cell Development
Authors: Han Jianxun , Zúñiga-Pflücker Juan Carlos
Published: January 2021

The thymus is an intricate primary lymphoid organ, wherein bone marrow–derived lymphoid progenitor cells are induced to develop into functionally competent T cells that express a diverse TCR repertoire, which is selected to allow for the recognition of foreign Ags while avoiding self-reactivity or autoimmunity. Thymus stromal cells, which can include all non–T lineage cells, such as thymic epithelial cells, endothelial cells, mesenchymal/fibroblast cells, dendritic cells, and B cells, provide signals that are essential for thymocyte development as well as for the homeostasis of the thymic stroma itself. In this brief review, we focus on the key roles played by thymic stromal cells during early stages of T cell development, such as promoting the homing of thymic-seeding progenitors, inducing T lineage differentiation, and supporting thymocyte survival and proliferation. We also discuss recent advances on the transcriptional regulation that govern thymic epithelial cell function as well as the cellular and molecular changes that are associated with thymic involution and regeneration.

As a specialized offshoot of Tele-medicine, Tele-intensive care unit (Tele-ICU) offers an innovative solution in the care of critically ill COVID-19 patients, by off-site clinicians, using audio, video, electronic, and tele-communication links to leverage technical, informational, and clinical resources. Tele-ICU also helps overcome the shortage of expertise like intensivists in these settings and helps to take the clinical expert to the patient bedside by remote monitoring and supervision. Telemedicine applications can be classified into four basic types, according to the mode of communication, timing of the information transmitted, the purpose of the consultation, and the interaction between the individuals involved-be it doctor-to patient/caregiver or doctor to doctor. The benefits and concerns of tele-medicine have been described in detail.
Successful application of early tracheostomy in an intubated patient who suffered from irritative stimuli by an oral tracheal tube

We experienced a case in which simultaneous weaning from sedation and mechanical ventilation were difficult because of instability of tracheal tube fixation that was caused by size mismatch between the trachea and the tube and by severe tracheal deviation. Irritative stimuli caused by the oral tracheal tube prevented conversion from deep sedation to light or no sedation. In this case, very early tracheostomy, which provided better tube fixation and successfully reduced the irritative stimuli to the trachea, was effective to help achieve discontinuation of sedation and facilitated successful weaning from mechanical ventilation. Eventually, the tracheostomy tube was successfully removed immediately after discontinuation of mechanical ventilation.

Hecht–Beals syndrome (HBS) is a rare disorder characterized by trismus and deformity of the extremities. The etiology of trismus is unknown; theories suggest invasion of enlarged coronoid processes into the zygomatic bone. Of primary concern is the limited mouth opening and possible difficult airway. Since the syndrome was first described in 1969, there have been several articles in the pediatrics and dental literature but only 6 case reports describing the anesthetic management of these patients. Successful airway approaches have utilized various techniques including blind nasal intubation, fiberoptic intubation, and tracheal tube introducer guidance. In this case report, we discuss a multidisciplinary approach to the anesthetic management of a child with HBS undergoing MRI and outpatient surgery.
Retrieving multiple magnetic foreign bodies from the glottic entrance and stomach

Aspiration and ingestion of foreign bodies present a frequent challenge in pediatric anesthesia practice that requires careful planning of the time and the method of retrieval. We discuss the management of a 20-month-old boy who had ingested multiple small magnetic beads and presented emergently to the operating room with two beads lodged in the vallecula and eighteen more forming a chain in the stomach. Benefitting from their magnetic properties, the beads located close to the glottic entrance could be removed by placing a steel Magill forceps close to the objects and using magnetic pull rather than grasping. The beads in the stomach were removed en bloc due to their magnetic properties using an endoscopic retrieval basket. Small beads can be difficult to remove, however, in this case it was possible to utilize their magnetic properties during the removal process.

Kegiatan pengabdian pada masyarakat ini dilatarbelakangi adanya permasalahan pada mitra, yaitu kebanyakan guru-guru belum pernah menggunakan aplikasi atau media pembelajaran matematika yang menarik dan inovatif. Mereka sebagian besar mengajar dengan berceramah dan berdiskusi di kelas. Walaupun sudah menggunakan alat peraga, namun dirasa kurang menarik dan inovatif. Diperlukan adanya media pembelajaran yang dapat memfasilitasi guru SD/MI dalam kegiatan mengajar di kelas agar siswa tertarik dan antusias saat belajar matematika. Kegiatan workshop akan dilakukan pada siswa dan guru MI Al Iman dengan alasan sekolah memiliki masalah, yaitu banyak guru yang masih mengalami kesulitan cukup tinggi dalam menggunakan media atau aplikasi dalam pembelajaran matematika.
Pengabdian pada masyarakat ini bertujuan untuk meningkatkan keterampilan guru dalam menggunakan GeoGebra sebagai media pembelajaran matematika di SD/MI. Workshop dilaksanakan dengan metode diskusi, pengayaan materi matematika di SD dan workshop yang meliputi tutorial penggunaan aplikasi GeoGebra. Kegiatan pengabdian pada masyarakat ini dilaksanakan selama 4 bulan yang diikuti oleh 20 guru MI Al Iman.

Bibliotherapy: A Framework for Understanding Pre-Service Primary Teachers’ Affective Responses to Learning and Teaching Mathematics
Authors: Wilson Sue , Thornton Steve
Published: January 2021

This paper advocates bibliotherapy as a powerful tool through which teacher educators can analyze and interpret the affective responses of pre-service primary teachers. Pre-service teachers analyzed readings about school students’ learning, and reflected on and reconstructed their understanding of their own school experiences. This process facilitated a meta-affective change that enabled the pre-service teachers to reconsider their assessment of their capacity to learn and understand mathematics. We describe this change using the stages of bibliotherapy. This change enabled the pre-service teachers to approach their future teaching of mathematics with greater enthusiasm, and empowered them to construct positive projective identities.
