Multiple Goals for Biomass Residues in Circular Bioeconomies? Assessing Circularities and Carbon Footprints of Residue-Based Products
Authors: Olofsson Johanna 
Published: September 2024

AbstractBiomass residues are often considered key in a reorientation towards circular bioeconomies, both by returning organic matter and nutrients to soils and by expanding the feedstock base for fossil-free products. Different indicators are available to assess progress towards circularity, but many available indicators and assessments seem to focus on product or material circularity, and lack in coverage of ecological or nutrient circularity. This study therefore applies both material and nutrient circularity indicators to two cases of residual biomass’ valorisation: plastics production from wheat straw, and jet fuel production from animal by-products, in order to better understand the potential of the different types of indicators to assess the circularities of bio-based products.Both the studied production systems achieve approximately 50% material circularity in the base case, but the scores are significantly lower when upstream processes such as cultivation and animal husbandry are included. In the plastics case, the nutrient circularity scores are consistently lower than material circularity scores. The contribution to circularity from composting and recycling of different streams can be interpreted differently following the different types of circularities and, in addition, considering the potential climate impact of different strategies. This study shows that a combination of methods and indicators can shed light on different types of circularities and goals, but also that a wider discussion on what circularity may entail for biomass and biomass residues, and how it can be measured, is needed to develop useful indicators for bio-based circularity and circular bioeconomies.

Published: September 2024

AbstractThe Nigeria Government through the Energy Commission of Nigeria has been promoting biomass as one of the renewable energy sources with little emphasis on biogas technology. These efforts were meant to encourage the adoption of alternate sources of energy and shift from traditional forms of energy like firewood which have devastating effects on the environment. A policy reviewed of was conducted and identified that Nigeria’s Energy Policy has no technology listed to aggregate and deploy biogas as a tool for Nigeria’s climate goals and enhance energy access. This study aims to investigate through scientific and policy review of how biogas technology penetration could be legislated in the Nigeria energy policy. Works of literatures reviewed (over 70 scientific articles) revealed that policy among other factors is prominent as the main caveat that limits the penetration of biogas technology in many developing countries including Nigeria. Social acceptance, awareness and availability of feedstock are also regarded as part of the challenges facing adopting biogas technology as an alternative clean energy source. The current study has also presented a strategic policy framework that could be considered for biogas policy adoption. In addition, the study has revealed that identification and appropriate stakeholder consultation is key to enhance achieving a holistic policy that fully supports biogas technology in Nigeria. The study has provided robust policy recommendations for deploying biogas technology in the Nigeria energy policy.
Novel approach for solving fractional partial differential equations using conformable Elzaki Transform
Authors: Elzaki Tarig M. , Ahmed Shams A. 
Published: September 2024

AbstractThis article discusses three different kinds of fractional partial differential equations (FPDEs) and how to solve them. First, a reformulation of the conformable fractional Elzaki Transform (ET) method is shown. The proposed methodology is then applied to the solution of three different types of FPDEs. The effectiveness and dependability of the proposed strategy are found to be validated by numerical simulations. We believe the provided strategy is very successful and straightforward to adapt of many types of FPDEs. This method is one of the completely new approaches for solving FPDEs because of its exceptional correctness and speed, which set it apart from other approaches.

Published: September 2024

AbstractTo investigate the effects of surface roughness and load on friction and wear behavior, Si3N4 balls and GCr15 bearing steel were selected as the rotating friction pair. The pin-on-disc wear test was carried out under different loads and surface roughness. The experimental results indicate that as the initial surface roughness of the GCr15 bearing steel specimen and applied load increase, the width and depth of the wear tracks also increase, and the wear resistance performance deteriorates. Correlation dimension D and enclosing radius R were used to characterize the running-in quality during the stabilization wear stage. The higher the correlation dimension and the smaller the enclosing radius, the better the running-in quality. The results show that when the initial surface roughness Rq is 0.009 μm, and the applied load is 40N, the corresponding correlation dimension is the highest, and the enclosing radius is the smallest, indicating the best running quality. Conversely, when the initial surface roughness is 1.192 μm, and the applied load is 20N, the corresponding correlation dimension is the smallest, and the enclosing radius is the largest, indicating the worst running-in quality. The running-in quality is related to the initial surface roughness, with lower initial surface roughness resulting in higher running-in quality. The effect of load on running-in quality is complex due to the complexity of the friction system.
Dementia caregiving during the COVID-19 pandemic: an interpretative phenomenological analysis of caregivers’ experiences
Authors: Pinto-Grau Marta , Blanco-Campal Alberto , Bramham Jessica 
Published: September 2024

Abstract

Objective:
To explore the lived experience of informal dementia caregivers during the COVID-19 pandemic.

Methods:
Interpretative Phenomenological Analysis (IPA) was employed. Eight primary informal caregivers were recruited from a community mental health service for older people when attending in their role as caregiver of a service-user. Semi-structured interviews were conducted at home or in the clinic based on the participants’ convenience and preference. IPA was completed following Smith and colleagues framework for analysis.

Results:
Six group experiential themes, each with a number of subthemes, emerged from the cross-case interpretative analysis: the ambivalent experience of caregiving (subtheme: those complex emotional experiences); navigating lockdown: lived challenges and opportunities (subthemes: the pervasive fear, intensification of existing struggles, being prevented from caring for a loved one, and lockdown as a time for opportunity); transitioning out of lockdown (subthemes: regaining freedom, but restricted freedom after all and being in a lockdown of one’s own); the present with COVID-19, but mostly with dementia (subthemes: dementia, a disease that does not pause, and ‘takeaways’ from the journey); looking into the future (subthemes: embracing COVID-19 and the true needs); and a word on coping (subtheme: managing it all as best one can).

Conclusion:
Findings demonstrate the significance of the meaning caregivers ascribed to their experiences on their wellbeing and ability to cope in times of COVID-19 and thereafter. Gaining an understanding of the caregivers’ unique experiences is crucial to appreciate how to best support them.
Fluid–acoustic–structure resonance mechanism of a plane cascade via a low-speed wind tunnel test

Published: September 2024

Acoustic resonance is an important factor that contributes to aeroengine compressor failure. In this study, a plane cascade of compressor blades was designed to reproduce acoustic resonance via a low-speed wind tunnel test. A high-frequency hot-wire, microphone and strain gauge were used to synchronously measure the fluid, acoustic and structural parameters. We analysed the variation in the amplitude and frequency of the multi-field parameters with increasing mean flow velocity and explored the multi-field interaction mechanism that induces the acoustic resonance of the plane cascade. The plane cascade effectively reproduced the acoustic resonance phenomenon. The first-order acoustic-mode frequency of the plane cascade flow duct, second-order torsional vibration mode frequency of the blade and shedding mode frequency of the tip clearance leakage vortex were equal under acoustic resonance. The fluid, acoustic and structural fields showed a strong interaction effect, achieving the maximum blade vibration amplitude and causing fatigue cracks of torsional vibration at the blade root. The frequency lock-in region of the compressor plane cascade was divided into an ‘acoustic–structure’ interaction region, a ‘fluid–acoustic–structure’ interaction region and a first-order acoustic-mode dominant region with increasing mean flow velocity, which demonstrates an interesting phenomenon in which the fluid–acoustic–structure modes compete: acoustic mode > blade vibration mode > vortex shedding mode. The results demonstrate a unique approach to the study of acoustic resonance that provides insight into the acoustic resonance mechanism in a cascade of compressor blades.
Effectiveness of a nutrition education intervention using simulation videos and encouragement of parental involvement for elementary school students

Published: September 2024

Abstract
This study aims to develop a nutrition education intervention to promote healthy eating, and to evaluate the effectiveness of this intervention on healthy eating knowledge, attitude and behaviour among elementary students. A quasi-experimental study was conducted in two elementary schools in Taiwan. The intervention course design included simulation videos, lectures, and the after-school learning worksheet designed for parental involvement. A total of 4 courses along with 4 simulation videos were given to the intervention group. The four course themes were Sugar patrol, Balanced Diet during the Mid-Autumn Festival, Rainbow Fruit and Vegetables, and Smart Dine Out. The study recruited 35 3rd grade students for the intervention group and 30 for the control group. Data were collected from the pre- and post-test questionnaires. The nutrition intervention had significant effects on improving participants’ knowledge about tips for making healthy choices and the necessity of balanced diet, and on attitude toward healthy eating. There was no significant improvement in participants’ healthy eating behaviours. This nutrition education intervention, which utilized simulation videos and encouraged parental involvement, could be recommended for teaching practice in elementary schools to improve healthy eating knowledge and attitude among students.
Participatory clientelism: A socio-spatial approach to popular politics in Buenos Aires
Authors: Halvorsen Sam , Mauro Sebastián 
Published: September 2024

AbstractWhat is the relationship between clientelism and political participation in popular urban neighborhoods? This article addresses the question based on qualitative research in two popular neighborhoods of Buenos Aires, drawing on participant observation and interviews with residents, activists, and party brokers. Adding to a growing literature on “participatory clientelism,” we argue for greater attention to the urban context through which this unfolds. To date, research into participatory clientelism has predominantly considered specific practices—participatory innovations or contentious politics—and been limited to the survival of the urban poor and the demand for political support by party brokers. While these are crucial practices, they are not exhaustive of the relations that sustain participatory clientelism, particularly in contexts of territorialized politics. Based on the socio-spatial approach of Henri Lefebvre, influential in urban studies, we define three interconnected dimensions of participatory clientelism and identify them in the cases under study.
Finding and sorting in hybrid memory practices: ‘doing memories’ in connection with the logic of Facebook
Authors: Ekelund Robin 
Published: September 2024

Abstract
This article investigates memory practices in connection with retrospective Facebook groups created for remembering specific aspects of the past. It focuses on how members of these groups experience and deal with how Facebook's interface and algorithms enable, shape, and interfere with memory practices. From this point of departure, the article discusses and nuances the idea that a ‘connective turn’ has brought with it an ontological shift in memory culture (Hoskins 2017a) and a ‘greying’ of memories (Hoskins and Halstead 2021). Theoretically, the article draws on Deborah Lupton's (2020) concept of ‘data selves’, which offers an account of how people interact with data and technology. This concept does not view data practices as immaterial but rather as material, corporeal, and affective, thus prompting an understanding of memory practices as hybrid processes where offline and online practices intersect (Gajjala 2019; Merrill forthcoming/2024). In this qualitative study, nine members of retrospective Facebook groups were chosen to participate in semi-structured interviews. The analysis explains the importance of viewing contemporary memory practices as hybrid, showing a greying effect within the affordances of Facebook that shapes both which memories are shared and how memories are shared. In addition, the analysis nuances the idea of an ontological shift in memory culture and the greying of memories by investigating how the interviewees’ deal and struggle with the affordances of the platform in their memory practices.
How social memory works on social media: A methodological framework
Authors: Ben-David Anat , Meyers Oren , Neiger Motti 
Published: September 2024

Abstract
Social media challenge several established concepts of memory research. In particular, the day-to-day mundane discourse of social media blur the essential distinction between commemorative and non-commemorative memory. We address these challenges by presenting a methodological framework that explores the dynamics of social memory on various social media. Our method combines top-down data mining with a bottom-up analysis tailored to each platform. We demonstrate the application of our approach by studying how the Holocaust is remembered in different corpora, including a dataset of 5.3 million Facebook posts and comments collected between 2015 and 2017 and a 5 million Tweets and Retweets dataset collected in 2021. We first identify the mnemonic agents initiating the discussion of the memory of the Holocaust and those responding to it. Second, we compare the macro-rhythms of Holocaust discourse on the two platforms, identifying peaks and mundane discussions that extend beyond commemorative occasions. Third, we identify distinctive language and cultural norms specific to the memorialization of the Holocaust on each platform. We conceptualize these dynamics as ‘Mnemonic Markers’ and discuss them as potential pathways for memory researchers who wish to explore the unique memory dynamics afforded by social media.
From Cadarese to Morasco: the creation of a Fascist hydroscape in alpine space after 1928
Authors: De Pretto Sebastian 
Published: September 2024

Abstract
This article explores the socio-ecological impacts of Fascist hydropower extraction in the Alpine valleys of Italy, focusing on the Toce river basin during the interwar period. It investigates the conflicts between local communities and hydropower initiatives by private energy companies under Fascism, thereby revealing the regime's communication strategies rooted in its political ecology. By analysing newspaper articles, propaganda outlets and communal archival documents, the study uncovers statal and local perspectives on infrastructure development and its enduring consequences. How the political ecology of Fascism in a high-altitude hydropower construction site became an expression of Fascist modernity will thereby be shown. Despite objections from valley inhabitants, Fascist hydropower projects persisted, perpetuating socio-ecological inequalities after 1945. Even postwar efforts for compensation failed to address the long-lasting impacts on mountain communities. This research reveals the intersection of political ecology and modernist infrastructure development in Mussolini's Italy, and thus also highlights the legacies of Fascist resource extraction policies on the country's peripheral Alpine regions.
Multiplicative dependence of rational values modulo approximate finitely generated groups
Authors: BÉRCZES ATTILA , BUGEAUD YANN , GYŐRY KÁLMÁN , MELLO JORGE , OSTAFE ALINA , SHA MIN 
Published: September 2024

AbstractIn this paper, we establish some finiteness results about the multiplicative dependence of rational values modulo sets which are ‘close’ (with respect to the Weil height) to division groups of finitely generated multiplicative groups of a number field K. For example, we show that under some conditions on rational functions
$f_1, \ldots, f_n\in K(X)$
, there are only finitely many elements
$\alpha \in K$
such that
$f_1(\alpha),\ldots,f_n(\alpha)$
are multiplicatively dependent modulo such sets.
Why does perceived parenting in adolescence predict maladaptive personality in adulthood? Evidence for substantial genetic mediation

Published: September 2024

Abstract
Why is parenting in adolescence predictive of maladaptive personality in adulthood? This study sets out to investigate environmental and genetic factors underlying the association between parenting and maladaptive personality longitudinally in a large sample of twins. The present study addressed this question via a longitudinal study focused on two cohorts of twins assessed on aspects of perceived parenting (parent- and adolescent-reported) at age 14 years (n =1,094 pairs). Participants were followed to adulthood, and maladaptive personality traits were self-reported using the Personality Inventory for DSM-5 (PID-5) at age 24 or 34 years. We then modeled these data using a bivariate biometric model, decomposing parenting-maladaptive personality associations into additive genetic, shared environmental, and nonshared environmental factors. Numerous domains of adolescent-reported parenting predicted adult maladaptive personality. Further, we found evidence for substantial additive genetic (r
a
ranging from 0.22 to 0.55) and (to a lesser extent) nonshared environmental factors (r
e
ranging from 0.10 to 0.15) that accounted for the association between perceived parenting reported in adolescence and adult personality. Perceived parenting in adolescence and maladaptive personality in adulthood may be related due to some of the same genetic factors contributing to both phenotypes at different developmental periods.
What drives the growth of an open pension fund?
Authors: Chiesi Gian Marco , Valletta Mario , Zocchi Paola 
Published: September 2024

Abstract
This paper investigates the relationship between growth and quality of pension funds. It measures growth in terms of changes in the number of participants and cash flow transfers and appreciates the quality of the funds through the set of information on past results and costs published in the official prospectuses. The results show that growth rewards the best performing funds in the long term, while annual performance and costs have no relevance. Nevertheless, other factors, such as market power and commercial pressure, appear to be more powerful. The existence of conditions of market power capable of attracting investors beyond the actual quality of pension products is undesirable as it harms future pensioners. These results have implications for the Authority, as mandatory information should be suitable to induce investors to identify the best products and direct individual choices toward the public objective of a more efficient market.
An Adventure for All Ages: History, Post-Memory, and Romance in Tomasz Różycki's Twelve Stations
Authors: Wodzyński Łukasz 
Published: September 2024

AbstractThe article examines Tomasz Różycki’s 2004 mock epic Twelve Stations. The poem recounts an oneiric tale about a community of expatriates from Poland’s Eastern Borderlands who send their grandson on a mission to assemble a scattered family and guide it to their lost homeland in today’s Ukraine. Revolving around the issues of memory, post-memory, and nostalgia, Twelve Stations draws heavily from the adventure tradition to present a fresh perspective on modern Poland’s founding myths: the loss of Borderlands and settling the post-German territories in the West. Reading the poem in the context of cultural memory studies and focusing on the author’s deployment of adventure tropes and patterns, the article argues that Różycki’s poetic tale de-politicizes the existing narratives affixed to forced resettlements by weaving them with various strands of popular romance. In doing so, the poem imagines a collective act of “working through” the trans-generational trauma resulting from physical and cultural uprooting. Różycki’s inventive use of the form demonstrates that adventure narratives can be effective vessels of cultural memory, capable of repurposing elements of official narratives and nostalgic imagination to initiate more constructive and future-oriented identity-building processes.
Why Was Lina Shtern Not Executed? An Academic's Strategy of Survival in the Late Stalinist Period
Authors: Mayofis Maria 
Published: September 2024

AbstractThe Soviet physiologist Lina Solomonovna Shtern (1875—1968) was the only defendant in the trial against the Jewish Antifascist Committee who was not sentenced to death; the circumstances surrounding the court’s leniency toward her have long remained unknown. Shtern was sentenced to five years in exile and even her belongings were not confiscated. Her story has become the stuff of legends and much speculation. My paper reconstructs the particular circumstances surrounding the court’s decision to give Shtern a more lenient sentence and considers how the politics of science in the late 1940s and early 1950s could have influenced this decision and helped Shtern elaborate her own strategy of survival. I argue that the main reason for sparing Shtern’s life was her essay “On Cancer” written in the prison cell in the late 1951—early 1952. My work is based on a careful analysis of documents from Shtern’s personal archive and of the context of Soviet and North American medicine.
