Zinc recovery from hazardous construction wastes via an integrated process of the air classification, alkaline leaching, and water washing
Authors: Li Qiang , Zhao Youcai , Liu Kefu 
Published: May 2022

AbstractZinc‐ and lead‐containing wastes are often mixed with construction and demolition wastes in many factories, generating abundant of heavy metal‐enriched hazardous waste. In the present study, a novel integrated process of air classification, alkaline leaching, and water washing dechlorination was proposed for the efficient recycling of Zinc (Zn) resources. The first air classification process was realized via venturi tube, wherein the content of Zn could increase by 20 wt.%. After that, the product underwent an alkaline leaching process. Results showed that Zn recovery rate increased with fine particle sizes, and a 65% recovery rate was obtained under the following conditions of 5 mol/L NaOH, liquid/solid 10:1, and leaching time 1 h. Finally, water washing associated with microwave and ultrasonic treatments could remove over 85% of Cl and other water‐soluble salts. All the results indicated that the integrated method had an excellent recovery rate for Zn resources from construction and demolition wastes.
Islam, Social Work and Common Good in the Muslim Minority Context of Europe: Rethinking Shariʿa as Relational Ethics
Authors: Sahin Abdullah 
Published: May 2022

AbstractThis chapter explores the interface between Islam, social work and the common good within the Muslim minority context of Europe. The ethics-law nexus in Muslim tradition is examined to argue for a transformative Islamic engagement with the secular public space. Literature on Islam and social work is limited to providing basic information about Islam to frontline practitioners. The current inquiry intends to develop an Islamic perspective on social work and wellbeing. Increasing association of Muslims with extremism form negative public perceptions of Islam in Europe. Within this discourse of suspicion, Islam is coded as a cause of public harm and ‘Shariʿa law’ is often associated with human rights violations. This study argues that a critical dialogue among the faith-embedded and secular traditions of social ethics in Europe remains vital to fostering a shared sense of common good. Contemporary discussions on social ethics in Islam are dominated bymaqāṣid ash-sharī ʿa(objectives of Islamic law) andfiqh al-ʿaqalliyyāt(Muslim minority law). Whilst the former is purported to be a metaethical discourse and the latter implying a contextualising intent, both operate within strict juristic hermeneutics. Alternatively, this inquiry rethinks Shariʿa as relational ethics and practical wisdom (ḥikma), closer to the concept ofphronesisin ancient Greek philosophy, guiding human relations as imagined in Qurʾanic anthropology and its vision of a just society. Shariʿa is framed within Islam’s transformative view of human flourishing,tarbiyya. The notion of relational ethics is further grounded in dialogue with phenomenology-informed discussions on ethics, particularly in the work of Levinas, and Habermas’s ‘theory of communicative action’.
Social Work and Muslim Welfare: A Women’s Grassroots Association
Authors: Schröer Jussra , Ürek Birsen 
Published: May 2022

AbstractReligion, religiosity and spirituality are gaining importance for social work in Germany as a discipline and as a profession, especially in the context of Muslim people seeking advice. Most Muslims regard Islam as a social religion which helps in different life situations. For them, the central elements of their belief, such as mercy, charity, solidarity and assisting each other, are core elements of help in society. The purpose of this chapter is to show the importance of the real life experiences of people who seek advice in social work. In this context, the chapter shows that counselling is subject-, task- and context-related. Counselling deals with life realities and can address and solve specific problems, support individuals in making decisions and coping effectively with crises. At the least, a sensitive attitude towards religious questions provides an ability to deal constructively with the reality of life. Within this perspective, the practice model, the Meeting and Further Training Centre for Muslim Women, shows how it is possible to gain access to welfare issues in the context of religion and social work.
The Role of tawba (Repentance) in Social Work with Muslim Clients
Authors: Abdullah Somaya 
Published: May 2022

AbstractFor interventions to succeed in social work, practitioners need to be familiar with clients’ religious worldviews and value systems; by understanding these dimensions in a client’s life, appropriate coping behaviour in the context of their lived experiences can be enhanced. In working with Muslim clients, such intervention requires knowledge and awareness of Islam and of the concepts that Muslims rely on to deal with problems or to bring about change in their lives. These concepts provide a reference and motivation for change to occur and can be integrated into social work to ensure services are culturally sensitive for them.Tawba(repentance) is one such concept that is fundamental in Islam; it is considered a starting point for personal change and a means to achieve a new way of being in relation to others and to God.Tawbais defined religiously and spiritually; as religious doctrine, sin and transgression are emphasised, while spiritually, inner transformation is the focus. This paper examines the concept oftawbaand its use in social work to enhance intervention outcomes with Muslim clients.
Islamic Principles, Inclusivity and Revitalisation in Conceptual Frameworks for Western Social Work
Authors: Crabtree Sara Ashencaen 
Published: May 2022

AbstractIn considering the important contribution of Islamic principles and perspectives to social work, which has encompassed to-date both the etic (outsider) and an emic (insider) positionality, a dialectical stance is offered in this chapter. This takes a fused ‘etemic’ approach, where Islamic religious and cultural concepts are critically examined in a dialogical application towards and excursus of an adaptive understanding of how these abstracted notions can play out within a social work context. To this end, the following concepts: ʾumma, zakat, ʿizza and al-insān al-kāmil, which are Islamic beliefs or Muslim cultural practices, are discussed as offering powerful and evocative socio-cultural-religious constructs that can serve to illuminate professional social work. Such insights, however, are subject to caveats and qualifications regarding the contentious appropriateness of this kind of abstracted, discursive application as well as whether such concepts can or should be adopted in some fashion within social work. However, the International Federation of Social Work’s (IFSW) global definition of social work provides a useful porous framework for such a legitimate exercise in the IFSW’s attempts to depart from narrow ethnocentricism to both recognise and embrace the cultural diversity that constitutes this global profession.
Islamic Social Work within the Framework of the Welfare System: Observations from the German Case
Authors: Schmid Hansjörg 
Published: May 2022

AbstractThe development possibilities for Islamic social work are closely linked to the respective state’s welfare framework. The German system provides an insightful example, as it is characterised by a significant incorporation of religious welfare providers. In the sense of an “affirmative genealogy” (Hans Joas), the German welfare system can be understood as open to religious pluralism and social change. This chapter analyses interactions between the state, existing welfare organisations and Muslim providers, focusing on their respective legitimation strategies. Inclusive and more exclusive interpretations are presented by different parties. The openness towards all beneficiaries demanded of Muslim welfare providers could perhaps lead to a secularisation of Islamic social work. However, theological reflection enables an Islamic profile to be reconciled with general social responsibility.
New Perspectives in Critical Data Studies: The Ambivalences of Data Power—An Introduction
Authors: Hepp Andreas , Jarke Juliane , Kramp Leif 
Published: May 2022

AbstractData power is a highly ambivalent phenomenon and it is precisely these ambivalences that open up important perspectives for the burgeoning field of critical data studies: First, the ambivalences between global infrastructures and local invisibilities. These challenge the grand narrative of the ephemeral nature of a global data infrastructure and instead make visible the local working and living conditions, and resources and arrangements required to operate and run them. Second is the ambivalences between the state and data justice. These consider data justice in relation to state surveillance and data capitalism and reflect the ambivalences between an “entrepreneurial state” and a “welfare state”. Third is the ambivalences of everyday practices and collective action, in which civil society groups, communities, and movements try to position the interests of people against the “big players” in the tech industry. With this introduction, we want to make the argument that seeing data power and its irreducible ambivalences in a pointed way will provide an orientation to the chapters of this book. To this end, we first give a brief outline of the development of critical data studies. In part, we also want to situate the data power conferences, the most recent of which this volume is based on. This will then serve as a basis for taking a closer look at three facets of the ambivalence of data power.
Counting, Debunking, Making, Witnessing, Shielding: What Critical Data Studies Can Learn from Data Activism During the Pandemic
Authors: Milan Stefania 
Published: May 2022

AbstractThe COVID-19 pandemic has contributed to shift data power—the power of data structures as well as the power exerted by data on social life—in two directions. Key state functions and infrastructure are transferred to private corporations at the expenses of state sovereignty and oversight, while individual control over personal information such as political preferences and biomedical data is delegated to quasi-monopolistic platforms. Data activism as the civil society response to data power and the field of critical data studies in its role of the scholarly interpreter of a datafied society can both help us make sense of these challenges. Dialoguing with political sociology, this chapter explores data activism as a counterforce to predominant data power, takes stock of its most recent evolutions, and identifies pathways for critical data studies in the post-pandemic world. First, it distinguishes five focal strategies for data activists as they grappled with the challenges of the first pandemic within a datafied society: counting, debunking, making, witnessing, and shielding. It then singles out three challenges for data activism in the post-pandemic world, namely the question of infrastructure, the diffusion of data poverty, and scarce digital literacy. This chapter concludes by deriving lessons learnt from data activism during the pandemic that point to potential new perspectives for critical data studies in the post-pandemic world.
The Value Dynamics of Data Capitalism: Cultural Production and Consumption in a Datafied World
Authors: Bolin Göran 
Published: May 2022

AbstractThe metaphor that ‘data is the new oil’ points to the perception of data as a valuable resource in the form of raw material for algorithmic processing at the centre of data capitalism and its underlying process of datafication. While many point to broader consequences of datafication for social life there is still a need for analytical models to understand the complexity, scale, and dynamics behind these transformations. To focus on data as value is one such approach that is pursued in this chapter. The point of departure is Dewey’sTheory of Valuation(1939), which is discussed in relation to anthropological, sociological, and economic theories of value. The second section presents an analytical model for the study of the dynamics of data capitalism and the process of datafication. This is then illustrated with two examples that highlight the relations between the inner dynamics of data capitalism before the chapter ends with some conclusive recommendations for future empirical research.
Citizen Participation and ICT for Urban Development in Oslo
Authors: Giannoumis G. Anthony , Joneja Nidhi 
Published: May 2022

AbstractInformation and communications technologies provide a useful catalyst for promoting political participation in urban development. However, implicit biases often influence the design of those technologies, which can reinforce social disadvantages. Design processes can therefore create barriers that prevent or limit an individual’s or group’s ability to access or use technology and contribute to digital divides that segregate active users from users that experience barriers accessing or using technology. This chapter takes a universal design perspective, which is a design methodology and philosophy, that positions technology design as a means for ensuring participation in all aspects of society. This chapter explores the role of the design, development and implementation of participatory platforms as a mediators in citizen participation and urban development. The case study of a limited set of semi-structured interviews provides a basis for illustrating some experiences of citizens in Oslo who have used Si din mening, a participatory platform implemented by the city government. This chapter, therefore, sheds light on the ways in which local municipalities can ensure access and use of participatory platforms for as wide a population as possible. A heuristic analysis of one of the platforms provides further support and insights into potential patterns of use.
E-gentrification: Digital Community Engagement, Urban Change and Digital Rights to the City
Authors: Middha Bhavna , McShane Ian 
Published: May 2022

AbstractUrban development has, for many critical urban scholars, long been complicit with gentrification. The prolific scholarship on gentrification has also, in recent years, taken a digital turn, analysts exploring the association between gentrification and the increasing use of digital information and communication technologies (ICTs) in urban governance. This chapter extends the book’s discussion on consultative digital platforms as sites of dialogue between citizens and governments, situating these initiatives within the wider investment made by governments and commercial providers in digital urban infrastructure. This investment, supported by imaginaries such as techno-solutionism, democratic participation and ideas of a rational citizen, is shaping the social, economic and spatial dynamics of cities, bringing critical attention to what scholars, following Lefebvre, have called the digital rights to the city. We analyse data from the Melbourne case study of the DEMUDIG project to explore what we terme-gentrification—the convergent trajectories of digital ICTs and of the gentrification of formerly working-class urban locations. We contend, through using a framework of assemblage theory, that the implementation and use of digital engagement platforms may be a constituent of gentrification processes.

No self-advantage in recognizing photographs of one’s own hand: experimental and meta-analytic evidence
Authors: Holmes Nicholas P. , Spence Charles , Rossetti Yves 
Published: May 2022

AbstractVisually recognising one’s own body is important both for controlling movement and for one’s sense of self. Twenty previous studies asked healthy adults to make rapid recognition judgements about photographs of their own and other peoples’ hands. Some of these judgements involved explicit self-recognition: “Is this your hand or another person’s?” while others assessed self-recognition implicitly, comparing performance for self and other hands in tasks unrelated to self-other discrimination (e.g., left-versus-right; match-to-sample). We report five experiments with three groups of participants performing left-versus-right (Experiment 1) and self-versus-other discrimination tasks (Experiments 2 to 5). No evidence was found for better performance with self than with other stimuli, but some evidence was found for a self-disadvantage in the explicit task. Manipulating stimulus duration as a proxy for task difficulty revealed strong response biases in the explicit self-recognition task. Rather than discriminating between self and other stimuli, participants seem to treat self-other discrimination tasks as self-detection tasks, raising their criterion and consistently responding ‘not me’ when the task is difficult. A meta-analysis of 21 studies revealed no overall self-advantage, and suggested a publication bias for reports showing self-advantages in implicit tasks. Although this may appear counter-intuitive, we suggest that there may be no self-advantage in hand recognition.
Botanical composition of meadows and pastures and their role in the functioning of early medieval semi-artificial lake islands in Ziemia Lubuska (Lubusz land), western Poland
Authors: Maciejewska Karolina , Badura Monika , Noryśkiewicz Agnieszka M. 
Published: May 2022

AbstractContinuation of archaeobotanical and palaeoecological research on three semi-artificial lake islands, Nowy Dworek, Chycina and Lubniewice, has provided new information on the history, development and use of grasslands in Ziemia Lubuska (Lubusz land) in western Poland during the early Middle Ages. Pollen analysis reveals that the reduction in woodland and opening up of the regional landscape and the appearance of grassland communities there began around the 7th centuryad, which preceded the construction of the islands in the lakes. The analysis of plant macroremains collected from the settlement layers on these islands, of pollen from cores in the lakes and studies of the phytosociological plant communities of recent vegetation have helped to describe the botanical composition of these past meadows and pastures. The results show strong similarities between the three sites, which suggests that the local populations were using the same grassland types, which were on soils ranging from damp to rather dry and sandy. The main grassland in the vicinity of the islands included theMolinio-Arrhenathereteasyntaxonomical class of communities, althoughFestuco-Brometeagrasslands were also present. The presence of plant remains associated with various other types of meadows and pastures shows the diversity of habitats represented by the plant remains.
Electrical properties of amorphous Ge26InxSe74-x chalcogenide thin films
Authors: Abd El-Ghany W. A. , Salem A. M. , Teleb Nahed H. 
Published: May 2022

AbstractAmorphous Ge26InxSe74-x (1 ≤ × ≤ 5) chalcogenide thin films have been deposited by thermal evaporation technique. The temperature-dependence of DC conductivity and the temperature and frequency dependence of AC conductivity have been studied in the temperature range 295–523 K and in the frequency range 4–8 MHz. The study of the temperature-dependent of DC conductivity refers to the presence of two distinct conduction mechanisms; the activation energies for each were calculated and it was observed that their values decrease by increasing In content. Besides, in the low-temperature region, the variation of the conductivity against temperature was further analyzed according to the variable-range hopping model based on Mott’s relation, whereby the hopping parameters were evaluated. For all investigated compositions, the variation of the AC conductivity against frequency at the studied temperatures was interpreted according to the correlated barrier hopping (CBH) model which based on Jonscher’s power law, whereby the potential barrier height, WM, and the theoretical optical bandgap, Eg, were calculated.
Two-stage revision for periprosthetic joint infection in unicompartmental knee arthroplasty: clinical and radiological results
Authors: Cavagnaro Luca , Chiarlone Francesco , Mosconi Lorenzo , Zanirato Andrea , Formica Matteo , Burastero Giorgio 
Published: May 2022

Abstract
Introduction
Unicompartmental knee arthroplasty (UKA) has an infection rate of 0.1–0.8%. Despite the wide amount of literature about septic total knee arthroplasty management, few data are available for UKA infection treatment. The aim is to present the clinical and radiological outcomes along with complication rates of a series of septic UKA treated with two-stage exchange.

Methods
We retrospectively reviewed 16 patient treated with staged UKA revision for infection between June 2015 and September 2019 in a single bone infection unit. The main demographic and surgical data were recorded. Clinical scores (VAS, KSS, OKS, postoperative ROM), radiological parameters (osseointegration, loosening and radiolucencies) and complications were reported. The mean follow-up was 33.5 ± 6.9 months.

Results
Mean age at surgery was 68.5 ± 9.1. All but two were medial UKA. The mean number of previous surgeries was 2.9 ± 1.9. The mean ROM, VAS, KSS and OKS of the entire population improved significantly (p < 0.01). Radiological analysis did not show any migration or implant loosening. Ten constrained condylar and six posterior stabilized prosthesis were finally implanted. One intraoperative pathogen isolation was recorded and managed with suppressive therapy and good final outcome. The implant survivorship free from infection was 100% at the final follow-up. The overall survival rate for any reason of revision was 100%

Conclusion
According to our results, staged revision represents a reliable ad effective option in delayed and late UKA infections. This technique provides optimal clinical and radiological results with acceptable complication rates. To the best of our knowledge, this represent the widest case series on infected UKA managed with two-stage exchange.
