description: Automated vehicle (AV) acceptance relies on their understanding via feedback. While visualizations aim to enhance user understanding of AV's detection, prediction, and planning functionalities, establishing an optimal design is challenging. Traditional "one-size-fits-all" designs might be unsuitable, stemming from resource-intensive empirical evaluations. This paper introduces OptiCarVis, a set of Human-in-the-Loop (HITL) approaches using Multi-Objective Bayesian Optimization (MOBO) to optimize AV feedback visualizations. We compare conditions using eight expert and user-customized designs for a Warm-Start HITL MOBO. An online study (N=117) demonstrates OptiCarVis's efficacy in significantly improving trust, acceptance, perceived safety, and predictability without increasing cognitive load. OptiCarVis facilitates a comprehensive design space exploration, enhancing in-vehicle interfaces for optimal passenger experiences and broader applicability.

description: Following the overthrow of fascist rule in Italy by partisan forces in 1943, more than 650.000 Italian soldiers were categorized as military internees by Nazi Germany in order to circumvent international treaties prohibiting their use as forced labourers. Several thousands of these were forced to work in both private and public companies in Hamburg. Despite more recent Italian High Court sentences granting them a right to compensation, the German state denies them such rights, alleging that rather than being forced labourers they were treated as prisoners of war. The author describes the results of his research on various Hamburg-based companies that used Italian soldiers as forced labourers, civil society activities to commemorate the fate of these labourers and the political responsibilities of companies and politics with regard to the unmet demands made by prisoners and their families.

Joy Flunky: Why I Broke Up with Yoga to Gorge on Candy, Cat Videos and Porn

Subjects: Creative nonfiction -- Theses.

description: This thesis is an exploration of one woman's ultimate taboo: her own pleasure. A newspaper reporter by trade, I draw on philosophy, neuroscience, a personal narrative, and reporting to probe this underexplored area of our overexposed lives. It starts with my question, when did being good become more important than feeling good? My default mode is restraint: slicing donuts in half, indulging in two tiny chocolates during the workday, and nibbling only a sliver of sheet cake at office parties. The result is a life that should be perfectly joyful but is stunningly boring. I attribute these self-imposed constrictions partly to my Lutheran upbringing but mostly to a rabid dedication to yoga, which I've practiced for fifteen years and, for a time, taught. I ditch yoga and its cure-all promises. Pleasure becomes the priority. Because my pleasure impulse is so dusty, I enlist the help of a "play" expert. He inspires me to craft a pleasure to-do list that frames my adventures in hedonism, which range from hanging out with mermaids to dressing like a zombie to shooting a sniper rifle. The result is a meditation on letting go of ideas about who you are and exploring who you might become.

description: Joshua Clover outlines a theory of riots in his book Riot.Strike.Riot. Within the framework of this theory, he declares an end to the era of strikes and the beginning of the era of “Riot Prime.” This article argues against this by arguing, first, that the temporal and spatial sequence is not as clear as Clover implies and, second, that the hypothesis seems plausible only because Clover severely narrows the concept of strike while expanding the concept of riot. Finally, and with reference to the current feminist movement, the article formulates as a counter-hypothesis the assumption of a “feralization” of both types of resistance, of struggles both in the workplace and in the streets.

description: Modern Search Engine Results Pages (SERPs) present complex layouts where multiple elements compete for visibility. Attention modelling is crucial for optimising web design and computational advertising, whereas attention metrics can inform ad placement and revenue strategies. We introduce AdSight, a method leveraging mouse cursor trajectories to quantify in a scalable and accurate manner user attention in multi-slot environments like SERPs. AdSight uses a novel Transformer-based sequence-to-sequence architecture where the encoder processes cursor trajectory embeddings, and the decoder incorporates slot-specific features, enabling robust attention prediction across various SERP layouts. We evaluate our approach on two Machine Learning tasks: (1) regression, to predict fixation times and counts; and (2) classification, to determine some slot types were noticed. Our findings demonstrate the model's ability to predict attention with unprecedented precision, offering actionable insights for researchers and practitioners.

description: If a product deviates from its desired properties in the injection moulding process, its root cause analysis can be aided by models that relate the input machine settings with the output quality characteristics. The machine learning models tested in the quality prediction are mostly black boxes; therefore, no direct explanation of their prognosis is given, which restricts their applicability in the quality control. The previously attempted explainability methods are either restricted to tree-based algorithms only or do not emphasize on the fact that some explainability methods can lead to wrong root cause identification of a product's deviation from its desired properties. This study first shows that the interactions among the multiple input machine settings do exist in real experimental data collected as per a central composite design. Then, the model-agnostic explainable AI methods are compared for the first time to show that different explainability methods indeed lead to different feature impact analysis in injection moulding. Moreover, it is shown that the better feature attribution translates to the correct cause identification and actionable insights for the injection moulding process. Being model agnostic, explanations on both random forest and multilayer perceptron are performed for the cause analysis, as both models have the mean absolute percentage error of less than 0.05% on the experimental dataset.
An Examination of the Writings Of Brébeuf, Le Jeune, and Le Moyne in the Jesuit Relations; 1632-1659
Creators: name: Gregoire, Tasha
Publisher: name: The University of British Columbia
Year: 2013

description: The role of missionaries from the Society of Jesus was to travel the world to convert people to Catholicism. Jesuits were extensively trained at the society’s universities in preparation for missions. In 1632, missionaries were formally invited into New France. This thesis examines the writings of three Jesuit missionaries: Fathers Jean de Brébeuf, Paul Le Jeune, and Simon Le Moyne. Reports of the work that they did appeared in the Jesuit Relations. Through their entries in the Relations we learn that they adjusted the application of the training they received at the universities in France, modifying these according to the nature of their interactions with the Huron and Iroquois. The methods these Jesuits employed to convert indigenous people changed over the course of the missionary period. A close examination of topics such as illness, beliefs, conflict, politics, and interactions with indigenous peoples all had an effect on how these missionaries attempted to convert First Nations to Catholicism.

description: The author, a researcher on global supply chains and logistics, argues that the crisis in global logistics unfolding in 2020/21 can only be understood as one of the physical internet exposing a pre-existing, but hidden, fragility of supply chains. Contrary to fears of logistics managers who viewed cyber attacks as the most likely threat, the coronavirus crisis and the ensuing policies of “social distancing” proved that labour, both in production and in services, is the main force impinging on an unaltered flow of goods. While lorry drivers and seafarers were the groups of labourers most affected by the current crisis, the author argues that struggles over wages and working conditions that migrant labourers in logistics have maintained throughout the last decade offer glimpses of hope for a renewed cycle of social struggles.

Subjects: subject: Education -- Research papers (Graduate).

description: This study was designed to determine whether self-assessment and self-directed learning impacted student achievement for students in a third grade math classroom. Students were not randomly selected. The students were taught a self-assessment strategy as a whole group and it was reinforced in small group math instruction. At the beginning of the year, they were given a fall MAPP score to determine their baseline in math. During the study, they were given three pretest and posttests, as well as a winter MAPP test to determine their progress. The results indicate that there was a significant change in performance due to being taught self-assessment strategies.

description: Siren Song: A Story in Two Southern Worlds is a reported memoir that examines Southern culture in Italy and the United States. The thesis recounts my quest--through letters, photos, diaries, secondary sources, and interviews--to understand my Italian grandfather, Pietro Tavernise’s, radical decision to bring his wife and four children from Sorrento, Italy to Durham, North Carolina in 1957. The narrative alternates between Italy and North Carolina, connecting the ancient culture of Sorrento with the tobacco-tinged air of Durham. It draws parallels between my family’s two hometowns via the Southern threads of food, family, and fathers. In the course of recounting my family story, my thesis takes the reader to Southern Italy during and immediately after World War II and North Carolina during the decline of cigarette manufacturing, all while paying homage to the storytelling tradition of both regions, including the works of my late uncle, the author Reynolds Price.

description: The Royal Canadian Mounted Police is a central part of Canada’s national identity. In a 2013 poll, Canadians ranked the RCMP as the country’s fourth most important national symbol, behind only the Charter, the national anthem, and the flag. And yet, the RCMP’s recent history is littered with scandals: the Tasering death of Robert Dziekanski; sexual assault allegations within the force; a pension-fund impropriety; and the bombshell report by Human Rights Watch alleging widespread abuse by Mounties against Indigenous women in northern B.C.
To understand the RCMP’s present, I delve into its past, exploring the Mounties’ militaristic roots and most controversial episodes.  My analysis reveals an organization with a long history of dishonourable conduct, whose good reputation is due less to noble conduct than to fastidious public relations.
Ultimately, Canadians are responsible for the esteem in which they hold the Mounties. Ultimately, the RCMP’s future is entwined with Canada’s own sense of identity. Thus, to ask whether this institution – so rife with racism, sexism, anti-immigrant sentiment, and violence – can be fixed is to ask a more profound question: Is it only the RCMP that is broken, or do its challenges reflect deeper flaws in Canada’s own sense of itself?

description: McClure’s Experiment is a narrative history focused on the invention of American investigative journalism, told through the lens of the lives and stories of four journalists at McClure’s magazine. Irish immigrant S.S. McClure launched his magazine in New York in 1893. It reached its peak influence in early 1903, and imploded after a staff walkout in 1906. McClure was a visionary editor who discovered and mentored three journalists—Ida Tarbell, Ray Stannard Baker, and Lincoln Steffens. Together, their muckraking brand of journalism exposed the corruption of mob-run cities, like St. Louis and Pittsburgh, and precipitated the downfall of notorious tycoons and monopolies, in particular John D. Rockefeller and Standard Oil. The magazine also discovered important new voices in fiction, from Arthur Conan Doyle to O. Henry. At McClure’s, reportage and entertainment were equally leveled at America’s first mass readership, participating fully in Progressive Era activism and storytelling.

description: Pre-trained language models (PLMs) are trained on data that inherently contains gender biases, leading to undesirable impacts. Traditional debiasing methods often rely on external corpora, which may lack quality, diversity, or demographic balance, affecting the effectiveness of debiasing. With the rise of large language models and their extensive knowledge, we propose enhancing fairness (Fair-Gender) in PLMs by absorbing coherent, attribute-balanced, and semantically rich sentences. However, these sentences cannot be directly used for debiasing due to alignment issues and the risk of negative transfer. We address this by applying causal analysis to estimate causal effects, filtering out unaligned sentences, and identifying aligned ones for incorporation into PLMs, thereby ensuring positive transfer. Experiments show that our approach significantly reduces gender biases in PLMs while preserving their language expressiveness.

description: The ongoing coronavirus crisis has seen an increasing number of people participating in movements opposed to state measures to curb coronavirus waves in various countries. While these movements are often based on misinformation, the author holds that the reasons underlying them should be seen in an extremist interpretation of the term “freedom,” as epitomized in former US president Trump’s behaviour. This is an expression of new relations between labour and capital. It is incumbent on the left to wrest away the notion of “freedom” both from such politicians and from capital. Against voices demanding a prohibition of fascist groups following the latest fascist attack on Italian trade unions, the author holds that the left should seek to revalorize ideas such as solidarity and mutualism in order to counter radicalized neoliberal ideas. Referring back to the cycle of factory struggles in the 1970s, the author highlights the critical contribution exponents of that movement made to a critical understanding and implementation of public health policies.

description: The paper presents a short overview of the internal dynamics of the global working class during the coronavirus pandemic. Its four main strata – mass poverty, the working poor, blue-collar workers and white-collar workers – underwent a sharp process of differentiation. Moreover, they developed disproportionately: the strata of mass poverty and the working poor expanded, and the number of blue-collar workers shrank while white-collar workers experienced a new upswing. The social protection programs of the governments turned out to be a flash in the pan.

Publisher: name: The University of British Columbia
Year: 2014

description: We describe a non-pertrubative method of searching for solitary waves travelling through the magnetosphere of a magnetar. The wave will be supported by the combined effects of nonlinearity and dispersion caused by the presence of a quantum electrodynamic (QED) vacuum in a strongly magnetized field and by a strongly magnetized plasma of the magnetosphere. Using this method, we have found a soliton in the form of an infinite current sheet. The method and the results of this paper could be conducive to research studying the emission of strongly magnetized stars.

Zusammenfassend kann bei einer ganzheitlichen Betrachtung herausgearbeitet werden, dass die mentale Gesundheit insbesondere durch das Zusammenspiel von negativen Effekten des Work-Life-Conflicts und positiven Effekten des Work-LifeEnrichments beeinflusst wird. In diesem Zusammenhang sind auch die mediierenden Effekte der Selbstwirksamkeit als persönliche Ressource sowie die moderierenden Effekte des Job Craftings relevant, auch wenn die Effekte nicht sehr stark ausgeprägt sind.

Diversification of wood product market by increasing market shares in South Korea
Creators: name: Chung, Tae Jun
Publisher: name: The University of British Columbia
Year: 2013

description: The wood product industry in Canada has been one of the most important economic driver. The global financial crisis in 2009 considerably affected the global markets; the US housing market crashed and the demand for wood products dramatically decreased. As a result, the forest industry in Canada, especially in British Columbia, experienced a catastrophic failure; the sawmills had to be shut down and thousands of workers lost their jobs, because most of the forest companies in Canada relied on a single market, the US. In order to recover from the depression and to reduce the risk of being reliant on the US market, the Canadian wood industry started the market diversification. Currently, the largest importer of BC wood product is China, followed by the US. However, the export trend shows that the Canadian wood product industry is still focusing on these predominant markets and missing valuable opportunities for diversification in the other markets. To reduce the risk of being dependant on a few large markets, it is important to identify the new or existing markets with high potential for growth in wood product demand and possibilities for higher profit return. The wood product market in South Korea is showing one of the fastest growths with an increasing demand for supply. There are many opportunities for the Canadian forest industry to expand and increase the market shares in South Korea such as wood housing market. In addition, the wood product industry in South Korea is demanding more wood product supply than ever. Hence, Canada should focus on further market diversification through penetrating and expanding into South Korean wood product market.

description: Wavelet transforms have been a relevant topic in signal processing for many years. One of the most common strategies when designing wavelet transforms is the use of lifting schemes, known for their perfect reconstruction properties and flexible design. This paper introduces a novel 2D non-separable lifting design methodology based on deep learning architectures. The proposed method is assessed within the context of end-to-end lossless image compression. The attained results highlight a significant 99% reduction of the number of learnable coefficients, with a direct impact on the computational complexity, while still achieving higher compression performance when compared to other end-to-end state-of-the-art wavelet-based frameworks. The code for the models used to obtain the reported results are available at https://github.com/joaoparracho/2D-NSWT-LCLS.

description: The main goal of the present paper is to generalize the results of~\cite{TroLNM,TroBoch} in the following way: To be able to define $K_0(A)ø\C$-valued Lefschetz numbers of the first type of an endomorphism $V$ on a C*-elliptic complex one usually assumes that $V=T_g$ for some representation $T_g$ of a compact group $G$ on the C*-elliptic complex. We try to refuse this restriction in the present paper. The price to pay for this is twofold:
 (i) $ $ We have to define Lefschetz numbers valued in some larger group as $K_0(A)ø\C$.
 (ii) We have to deal with W*-algebras instead of general unital C*-algebras.
 To obtain these results we have got a number of by-product facts on the theory of Hilbert W*- and C*-modules and on bounded module operators on them which are of independent interest.

description: Let $\cal M$ be a Banach C*-module over a C*-algebra $A$ carrying two $A$-valued inner products $< .,. >_1$, $<.,. >_2$ which induce equivalent to the given one norms on $\cal M$. Then the appropriate unital C*-algebras of adjointable bounded $A$-linear operators on the Hilbert $A$-modules $\{ {\cal M}, < .,. >_1 \}$ and $\{ {\cal M}, < .,. >_2 \}$ are shown to be $*$-isomorphic if and only if there exists a bounded $A$-linear isomorphism $S$ of these two Hilbert $A$-modules satisfying the identity $< .,. >_2 \equiv < S(.),S(.) >_1$. This result extends other equivalent descriptions due to L.~G.~Brown, H.~Lin and E.~C.~Lance. An example of two non-isomorphic Hilbert C*-modules with $*$-isomorphic C*-algebras of ''compact''/adjointable bounded module operators is indicated.

description: Transparency is increasingly seen as a critical requirement for achieving the goal of human-centered AI systems in general and also, specifically, recommender systems (RS). However, defining and operationalizing the concept is still difficult, due to its multi-faceted nature. Currently, there are hardly any measurement instruments to adequately assess the perceived transparency of RS in user studies. Thus, we present the development of a measurement instrument that aims at capturing perceived transparency as a multidimensional construct. The results of our validation show that transparency can be distinguished with respect to input (what data does the system use?), functionality (how and why is an item recommended?), output (why and how well does an item fit one’s preferences?), and interaction (what needs to be changed for a different prediction?). The study is intended as a first iteration in the development of a reliable and fully validated measurement tool for assessing transparency in RS.

description: A new approach to the Lance-Blecher theorem is presented resting on the interpretation of elements of Hilbert C*-module theory in terms of multiplier theory of operator C*-algebras: The Hilbert norm on a Hilbert C*-module allows to recover the values of the inducing C*-valued inner product in a unique way, and two Hilbert C*-modules {M_1, <.,.>_1}, {M_2, <.,.>_2} are isometrically isomorphic as Banach C*-modules if and only if there exists a bijective C*-linear map S: M_1 --> M_2 such that the identity <.,.>_1 \equiv _2 is valid. In particular, the values of a C*-valued inner product on a Hilbert C*-module are completely determined by the Hilbert norm induced from it. In addition, we obtain that two C*-valued inner products on a Banach C*-module inducing equivalent norms to the given one give rise to isometrically isomorphic Hilbert C*-modules if and only if the derived C*-algebras of ''compact'' module operators are *-isomorphic. The involution and the C*-norm of the C*-algebra of ''compact'' module operators on a Hilbert C*-module allow to recover its original C*-valued inner product up to the following equivalence relation: <.,.>_1 \sim <.,.>_2 if and only if there exists an invertible, positive element $a$ of the center of the multiplier C*-algebra M(A) of A such that the identity <.,.>_1 \equiv a \cdot <.,.>_2 holds.

description: Erwerbsminderungsrenten sollen den Einkommensausfall bei dauerhafter Erkrankung abfangen. Sie sind zu Beginn grundsätzlich zu befristen, um die Rückkehr in Erwerbstätigkeit zu unterstützen. Immerhin etwa die Hälfte der Erwerbsminderungsrenten ist jedoch von Beginn an unbefristet. Für drei Viertel der Erwerbsminderungsrentner*innen ist nach Beginn der Rente Erwerbstätigkeit nicht von Bedeutung. Innerhalb von sechseinhalb Jahren ist etwa jede*r Siebte verstorben, und etwa jede*r Achte in Altersrente gewechselt. Unter den Personen mit Erwerbstätigkeit nach der Bewilligung einer Erwerbsminderungsrente ist der Anteil derjenigen mit (versuchter) Rückkehr in Erwerbstätigkeit sowohl bei Personen mit unbefristeter als auch befristeter Rente gleich niedrig (ca. 8 bzw. 9 Prozent) – ein Hinweis darauf, dass Anreiz bzw. Möglichkeit eines Wiedereinstiegs bei Zeitrenten nicht höher als bei unbefristeten Renten ist. Selbst wenn mit Erteilung einer Zeitrente die Perspektive auf Erwerbstätigkeit ausgerichtet ist, schlägt sich dies kaum bei Rehabilitationen nieder. Nur eine knappe Hälfte derjenigen mit Zeitrente erhielten eine Rehabilitationsmaßnahme der Rentenversicherung, unter denen mit einer unbefristeten Rente waren es etwa ein Drittel.

description: The present paper is a short survey on the mathematical basics of Classical Field Theory including the Serre-Swan' theorem, Clifford algebra bundles and spinor bundles over smooth Riemannian manifolds, Spin^C-structures, Dirac operators, exterior algebra bundles and Connes' differential algebras in the commutative case, among other elements. We avoid the introduction of principal bundles and put the emphasis on a module-based approach using Serre-Swan's theorem, Hermitian structures and module frames. A new proof (due to Harald Upmeier) of the differential algebra isomorphism between the set of smooth sections of the exterior algebra bundle and Connes' differential algebra is presented.

description: Hilbert(ian) A-modules over finite von Neumann algebras A with a faithful normal trace state (from global analysis) and Hilbert W*-modules over A (from operator algebra theory) are compared, and a categorical equivalence is established. The correspondence between these two structures sheds new light on basic results in $L^2$-invariant theory providing alternative proofs. We indicate new invariants for finitely generated projective B-modules, where B is supposed any unital C*-algebra, (usually the full group C*-algebra $C^*(π)$ of the fundamental group $π=π_1(M)$ of a manifold $M$). The results are of interest to specialists in operator algebras and global analysis.

description: We give a comprehensive introduction to a general modular frame construction in Hilbert C*-modules and to related modular operators on them. The Hilbert space situation appears as a special case. The reported investigations rely on the idea of geometric dilation to standard Hilbert C*-modulesover unital C*-algebras that admit an orthonormal Riesz basis. Interrelations and applications to classical linear frame theory are indicated. As an application we describe the nature of families of operators {S_i} such that SUM_i S*_iS_i=id_H, where H is a Hilbert space. Resorting to frames in Hilbert spaces we discuss some measures for pairs of frames to be close to one another. Most of the measures are expressed in terms of norm-distances of different kinds of frame operators. In particular, the existence and uniqueness of the closest (normalized) tight frame to a given frame is investigated. For Riesz bases with certain restrictions the set of closetst tight frames often contains a multiple of its symmetric orthogonalization (i.e. Löwdin orthogonalization).

description: We present a general approach to a modular frame theory in C*-algebras and Hilbert C*-modules. The investigations rely on the idea of geometric dilation to standard Hilbert C*-modules over unital C*-algebras that possess orthonormal Hilbert bases, and of reconstruction of the frames by projections and by other bounded modular operators with suitable ranges. We obtain frame representations and decomposition theorems, as well as similarity and equivalence results for frames. Hilbert space frames and quasi-bases for conditional expectations of finite index on C*-algebras appear as special cases. Using a canonical categorical equivalence of Hilbert C*-modules over commutative C*-algebras and (F)Hilbert bundles the results find a reintepretation for frames in vector and (F)Hilbert bundles. Fields of applications are investigations on Cuntz-Krieger-Pimsner algebras, on conditional expectations of finite index, on various ranks of C*-algebras, on classical frame theory of Hilbert spaces (wavelet and Gabor frames), and others. 2001: In the introduction we refer to related publications in detail.

description: The goal of the present paper is a short introduction to a general module frame theory in C*-algebras and Hilbert C*-modules. The reported investigations rely on the idea of geometric dilation to standard Hilbert C*-modules over unital C*-algebras that possess orthonormal bases, and of reconstruction of the frames by projections and other bounded module operators with suitable ranges. We obtain frame representation and decomposition theorems, as well as similarity and equivalence results. The relative position of two and more frames in terms of being complementary or disjoint is investigated in detail. In the last section some recent results by P. G. Casazza are generalized to our setting. The Hilbert space situation appears as a special case. For detailled proofs we refer to another paper also contained in the ArXiv.

description: Die voranschreitende Digitalisierung führt zu einer Pluralisierung von Lehr- und Lerninhalten; traditionelle Bildungsmedien stehen in Konkurrenz mit rund um die Uhr verfügbaren und einen Klick entfernten Wissensressourcen im Internet. So stellt das im Internet verfügbare, meist kostenfreie, Angebot eine Flexibilisierung und Individualisierung des Lernprozesses dar, bleibt die Qualität der Inhalte jedoch häufig ungeprüft. Das Erklärvideo kann als ein populäres Exempel der beschriebenen Dynamik gelten. Das Ziel dieser Arbeit ist die Entwicklung eines Bewertungsraster, das eine fundierte sprach- und mediendidaktische Bewertung von Erklärvideos ermöglicht und eine differenzierte und reflektierte Perspektive auf das Medium fördert. Für die Erprobung des Rasters werden fünf Erklärvideos zum Thema Kommasetzung analysiert, die kriteriengeleitet aus der Plattform YouTube ausgewählt wurden. Das Raster und die dazu vorgestellten Analysen sind zugleich als Beitrag zur aktuellen Diskussion zur Spezifik digitalisierungsbezogener Kompetenzen von Lehrkräften zu verstehen.

description: Let W be an integrable positive Hermitian q x q -matrix valued function on the dual group of a discrete abelian group G such that W^{-1} is integrable. Generalizing results of T. Nakazi and of A. G. Miamee and M. Pourahmadi for q=1 we establish a correspondence between trigonometric approximation problems in L^2(W) and certain approximation problems in L^2(W^{-1}). The result is applied to prediction problems for q-variate stationary processes over G, in particular, to the case where G is the group of integers Z.

description: Der Streit – Podcast über neue soziologische Literatur. Mit Robert Seyfert und André Armbruster. Wir diskutieren die aktuelle Studie von Massimo Airoldi: „Mashine Habitus. Toward a Sociology of Algorithms“ (2022, Polity Press). Wir streiten uns darum, inwieweit das Habituskonzept zur soziologischen Analyse von Algorithmen trägt, ob Airoldi das Potential der Theorie auch tatsächlich ausnutzt und inwieweit bestehende Ansätze für eine digitale Soziologie ausreichen.
