Point Of Departure Research Articles

On Sharks Unseen

Basking sharks are the planet’s second-largest fish, and in the summer they feed on plankton in the Sea of the Hebrides, in Scotland. Once hunted for the oil contained in their livers, basking sharks are now a protected species, with tour companies offering the possibility to see and even snorkel with them. There is no guarantee of a sighting, however. This essay takes as its point of departure one such unsuccessful attempt to find basking sharks, undertaken as part of a research trip to learn about the history of shark hunting in the north-east Atlantic. Engaging with literature from multispecies ethnography, the essay considers the implications of treating absences as a condition of research on underwater species. It asks what form the tenets of multispecies ethnography – such as arts of attentiveness, immersion, and sustained participation in the lives of others – can take in oceanic settings. It suggests that direct observation cannot always account for relations with the unseen, and that methodologically and conceptually, the non-encounter offers a way of thinking through the ways that human activity can contribute to the loss of other species.

Spanish causatives

Spanish, contrary to Catalan, French and Italian, allows causees to appear in pre-infinitival position. This paper takes as initial point of departure the asymmetries between the pre-infinitival position vs. the post-infinitival discussed in Ordóñez and Saab (2017). I provide a cartographic account in which more than one site for causees must be posited. This proposal follows the same reasoning that posits more than one subject position in the clausal spine (see for instance Cardinaletti 2004). I characterize the higher pre-infinitival position as a criterial position in the sense of Rizzi (2006, 2007). Following that proposal, I address the question of the interaction of case in this higher causee projection. I adopt Baker and Vinokurova’s (2010) proposal that UG must allow two ways for case resolution: case via agreement and dependent case. I will show that Spanish spoken in Catalonia is uniform in its case assignment solution of dative case for causees. I propose that the higher causee projection is an applicative head which assigns dative uniformly. However, for Catalan, Italian and French and many other dialects of Spanish, case assignment depends on the transitivity of the infinitival verb. In these varieties I invoke dependent case.

Derivation of Transcriptomics-Based Points of Departure for 20 Per- or Polyfluoroalkyl Substances Using a Larval Fathead Minnow (Pimephales promelas) Reduced Transcriptome Assay.

Traditional toxicity testing has been unable to keep pace with the introduction of new chemicals into commerce. Consequently, there are limited or no toxicity data for many chemicals to which fish and wildlife may be exposed. Per- and polyfluoroalkyl substances (PFAS) are emblematic of this issue in that ecological hazards of most PFAS remain uncharacterized. The present study employed a high-throughput assay to identify the concentration at which 20 PFAS, with diverse properties, elicited a concerted gene expression response (termed a transcriptomics-based point of departure [tPOD]) in larval fathead minnows (Pimephales promelas; 5-6 days postfertilization) exposed for 24 h. Based on a reduced transcriptome approach that measured whole-body expression of 1832 genes, the median tPOD for the 20 PFAS tested was 10 µM. Longer-chain carboxylic acids (12-13 C-F); an eight-C-F dialcohol, N-alkyl sulfonamide; and telomer sulfonic acid were among the most potent PFAS, eliciting gene expression responses at concentrations <1 µM. With a few exceptions, larval fathead minnow tPODs were concordant with those based on whole-transcriptome response in human cell lines. However, larval fathead minnow tPODs were often greater than those for Daphnia magna exposed to the same PFAS. The tPODs overlapped concentrations at which other sublethal effects have been reported in fish (available for 10 PFAS). Nonetheless, fathead minnow tPODs were orders of magnitude higher than aqueous PFAS concentrations detected in tributaries of the North American Great Lakes, suggesting a substantial margin of safety. Overall, results broadly support the use of a fathead minnow larval transcriptomics assay to derive screening-level potency estimates for use in ecological risk-based prioritization.

Where Have All the ‘Exiters’ Gone? Contextualising the Concept of Hard Euroscepticism

AbstractThe article analyses the impact of Brexit on hard Eurosceptic discourses in the Visegrád Group countries from 2015 to 2023. As the negative implications of Brexit for the UK economy became clear, many hard Eurosceptics softened their rhetoric, using the referendum as a proxy for a ‘hard’ exit. Whilst the classical soft–hard typology remains dominant amongst scholars in the study of Euroscepticism, the case of Brexit shows that long‐term principled opposition to the European Union (EU) can hide behind equivocal rhetoric. The article suggests studying the changing tactics of Eurosceptics by matching current EU and domestic contexts together with the long‐term points of departure of hard Eurosceptics.

Teachers’ attitudes toward regrets: A cultural comparative reading

This paper addresses how universal teachers’ attitudes toward regret are bound with Chinese cultural particularity. Arguments are developed through comparative perspectives: philosophic theoretical thinking vs. qualitative interpretive thinking, ideas conceived in theory vs. ideas enacted in practice, and cross-cultural interactions between Chinese culture and Christian/modern ‘Western’ culture. A total of 113 narratives published in Chinese journals of Chinese teacher regret that were revealed by teachers voluntarily in the past four decades serve as a concrete point of departure for theoretical comparisons. The universality of two main types of human attitudes toward regret are defended, while the particularity of cultural attitudes toward regret between China and the ‘west’ (corresponding to the earlier theoretical constructs of two attitude meta-types) is supplementarily explained through the compelling contrast of anti-coronavirus policies (policies of zero COVID or not). The phenomenon of Chinese teachers’ comfortable expression of regrets in public is finally discussed for its subtlety of creative transcultural exchange.

Expanding Political Capital: Why Social Democratic Women Participated in Middle-Class Feminist Educational Organisations in Sweden c.1890–1910

ABSTRACT This article seeks to introduce a new historical explanation as to why left-wing working-class women engaged in liberal, middle-class organisations during the first wave of feminism. The article specifically deals with middle-class associations and clubs that had educational purposes. Instead of focusing on the larger explanatory scheme of the power of patriarchal societal structures or bourgeois feminisms as a hegemonic force, the account revolves around the political educational functions of liberal feminist engagement for some politically active social democratic women in Sweden. The case of social democratic women who entered the liberal middle class educational organisation Tolfterna (the Dozen) is the point of departure for a micro-historical analysis of the political capital accumulation practices that class collaboration entailed. Finally, the article explores how working-class women’s choices and actions can be considered a group-specific strategy to expand their political resources to attain what is called feminist liberal political capital.

Genotoxic mode of action and threshold exploration of 2-methyl furan under 120-day sub-chronic exposure in male Sprague-Dawley rats

2-Methylfuran (2-MF) is an important member of the furan family generated during food thermal processing. An in-vivo multiple endpoint genotoxicity assessment system was applied to explore the genotoxic mode of action and threshold of 2-MF. Male Sprague–Dawley rats received 2-MF by oral gavage at doses of 0.16, 0.625, 2.5, and 10 mg/kg.bw/day for 120 days. An additional 15 days were granted for recovery. The Pig-a gene mutation frequency of RET and RBC showed significant increases among the 2-MF groups on day 120. After a 15-day recovery period, the Pig-a gene mutation frequency returned to levels similar to those in the vehicle control. The tail intensity (TI) values of peripheral blood cells at a dose of 10 mg/kg.bw/day significantly increased from day 4 and remained at a high level after the recovery period. No statistical difference was found in the micronucleus frequency of peripheral blood between any 2-MF dose group and the corn oil group at any timepoint. 2-MF may not induce the production of micronuclei, but it could cause DNA breakage. It could not be ruled out that 2-MF may accumulate in vivo and cause gene mutations. Hence, DNA, other than the spindle, may be directly targeted. The mode of action of 2-MF may be that it was metabolized by EPHX1 to more DNA-active metabolites, thus leading to oxidative and direct DNA damage. The point of departure (PoD) of 2-MF-induced genotoxicity was derived as 0.506 mg/kg bw/day.

A new paradigm for multi-fidelity continuation using parallel model refinement

Numerical path continuation is commonly applied to determine how limit states of dynamical systems evolve with a free parameter. For high-fidelity models of complicated nonlinear systems, the sequential nature inherent to continuation can become an unsurmountable obstacle. In the present work, we propose a new paradigm for obtaining the targeted solution curves in a parallelized way. The point of departure is a low-fidelity model, which is of lower order and/or neglects certain nonlinear/coupling terms. The simplifications must be as drastic as necessary to obtain an approximate solution curve with reasonable effort. A subset of relevant points along this approximate solution curve is then selected, and, departing there, points on the targeted solution branch of the high-fidelity model are then iteratively computed. It is important to note that the iterative correction towards the high-fidelity solution branch can be applied independently for each point, and is thus predestined for parallel computation. The proposed generic concept is exemplified for a selection of nonlinear vibration problems. Different types of system models, nonlinearities and analyses are considered, and the Harmonic Balance method is used in all cases to compute periodic limit states. In particular, it is shown that the proposed concept is applicable to modal and harmonic order refinement. Finally, it is shown that the concept is also interesting when instead of a model refinement a second system parameter (besides the continuation parameter) is varied, and it permits to robustly reach parameter ranges that are extremely difficult to obtain with conventional path continuation. The method is available, along with the presented numerical examples, as a branch PEACE (Parallelized Re-analysis Of Solution Curves) of the open source tool NLvib.

Whitework in Antebellum Maryland: A quilt study in the visual culture of whiteness

This article argues that quilts are important sources for close readings of the visual and material culture of whiteness when placed against the backdrop of political and social history. Quilt making provides a space for multimodal learning and offers points of departure for related curricular resources that are educational tools to promote racial justice. Using a/r/tography, this research investigates the visual and material culture of whiteness and the historical context that produces its meaning. This article considers two quilt blocks from Applique Sampler: Whitework in Antebellum Maryland, a collaboratively made quilt which is part of a larger art education project that chronicles the role of visual culture in the process of creating, securing, and maintaining white supremacy in specific periods of U.S.

Swamped in dinosaurs with LED lights: negotiating sustainability in a high-consumption society

Unsustainable patterns of consumption in affluent societies are at the heart of global climate and environmental challenges and seemingly highly resistant to change. While decades of research have revealed how consumption is deeply embedded in society, recently calls have been made for (re-)engaging with the systemic conditioning of consumption in studies of everyday practices. In this paper, we analyse the ways in which eco-conscious households in Norway (N=20) perform and negotiate sustainability in everyday life. With theories of practice as a point of departure, we combine Bente Halkier’s work on social interaction with Sherry B. Ortner’s conceptualisation of agency as power (dominance and resistance) and agency through ‘projects’ to study how sustainability is negotiated in the everyday. Through this framework we explore how consumers perform ‘sustainability projects’ and how these are defined through, constrained by and negotiated against everyday normativity and dominant socio-material arrangements. Our findings demonstrate the compromises, trade-offs and negotiations that participants engage in when balancing their sustainability projects against other social roles, expectations and goals, often carried out within socio-material arrangements that are scripted towards less sustainable options. Hence, they provide detailed insight into the boundedness of consumer agency, being both socially and materially negotiated and contextualised. While often undertaken as mundane actions, the challenges our participants experienced is ultimately part of negotiating consumer society, often experienced as a constant pressure towards more consumption as expansive consumption is embedded in, and embodied and habituated through, a wide range of social practices.

Intra-Party Democracy in Tanzania: Assessing Competitiveness of Party Leadership Selection

Abstract This study assessed competitiveness in selecting party chairpersons in Tanzania and the factors that shape the competitiveness. Data were generated from interviews with 27 stakeholders, structured questionnaires administered to 60 party members and a content analysis of official party documents. The study revealed that the selections are generally not competitive when assessed against parameters such as incumbent success rate, number of candidates and vote share among them and role of party Conventions. Specifically, possibility to defeat incumbents is generally very low while the selections mostly feature one candidate who amasses almost all votes. To camouflage competition, leadership selections in CUF and CHADEMA occasionally feature more than one candidate while single candidacy remains a strongly established tradition in CCM. Yet, delegates to party Conventions seem to be highly influenced by sitting chairpersons in selecting their new leaders. The findings reveal how intra-party democratic deficit normally builds itself around power centers of the party thus calling for further studies on intra-party democracy to use the party leadership as their point of departure. Practically, relevant laws should be redefined while also strengthening their enforcement mechanisms to compel political parties to cherish democratic principles in their internal businesses.

“Kuna Corona fake na Og”: The Role of Postcolonial Laughter during the COVID-19 Outbreak in Tanzania

Abstract Scholars are basically divided in their perception of the functions of postcolonial humour. One block ascribes it to the role of criticising postcolonial governments for maladministration. Another group ascribes it to ridiculing the masses for their passivity to unjust rulers. In addition, there is also a middle group that does not specifically assign the art to either side. Taking these varying opinions as a point of departure and the novelty of COVID-19 humour, the researcher adapted multimodality and social semiotics to analyse and ascertain the role of postcolonial humour used in debates about COVID-19 in Tanzania during the peak of the malady. In this regard, the study reports that besides entertainment function, COVID-19 postcolonial humour reminded people from all walks of life to take responsibility in the fight against the disease. Thus, the findings confirm that postcolonial humour in social media, like other traditional African verbal arts, criticises undesirable societal practices regardless of a person’s social and political status.

Players or Pawns? University Response to the Introduction of Plan S

The European Plan S initiative intending to transform the field of academic publishing towards open access has been received with both enthusiasm and criticism. This article reflects on this case as an example of how policymaking in ‘the Europe of Knowledge’ – characterized by increasing complexity caused by problems of multi-level coordination, combined with multi-actor divergence of norms, ideas, and interests − affects and triggers university responses. The analysis of response to this initiative for reform of scientific publishing takes the concept of normative match and mismatch as its theoretical point of departure, and the article provides an overview of how Plan S has been implemented in Norwegian higher education, where the challenge for universities has been to find a balance between responding to political expectations and expectations from societal and academic stakeholders. Our findings suggest a normative mismatch related to the Plan S initiative. The article argues that the university level was left with the task of defending the academic freedom of the individual scholar, while also being delegated the responsibility of controlling the rising costs of publishing services. As a result, issues relating to academic publishing are currently of strategic interest to universities.

The Sydney Declaration – An unique opportunity for Africa

The Sydney Declaration (SD) has the inherent virtue of shifting the focus from the tools used in forensic science to the fundamental characteristics of appropriate forensic practice analysis of a situation and all related trace data for the purpose of resolving a case. Though several differences might be observed between countries regarding the technologies used, the fundamental principle of forensic logical reasoning are universally applicable to all contexts and environments and not only restricted to sophisticated, well-resourced, established forensic science laboratories based in countries that offer adequate resources, strong networks and legal frameworks. In Africa, several countries lack resources to train practitioners and to develop forensic science institutes, laboratories and other relevant institutions. The SD can serve as departure point to attain appropriate forensic science outcomes. Upholding its sound guidance can help forensic science practitioners remain faithful to their science, acknowledge their limits, give expert opinions based solely on facts and scientific analysis and interpretation, whilst also enhancing communication with their stakeholders. As forensic science develops in Africa, the SD presents a timely opportunity for us to proceed with a common understanding and a solid foundation through which our field can grow.

Discriminant canonical analysis as a tool for genotype traceability testing based on turkey meat and carcass traits.

The present study aims to develop a statistical tool for turkey breed traceability testing based on meat and carcass quality characteristics. To this end, a comprehensive meta-analysis was performed, collecting data from a total of 75 studies approaching meat and carcass attributes of 37 turkey strains and landraces since the late 1960s. A total of 22 meat and carcass traits were considered variables, grouped in the following clusters: carcass dressing traits, muscle fiber properties, pH, colorimetry, water-capacity traits, texture-related attributes, and nutritional composition of the meat. Once the multicollinearity analysis allowed the deletion of redundant variables, cold carcass weight, slaughter weight, muscle fiber diameter, sex-female, carcass/piece weight, meat redness, ashes, pH24, meat lightness, moisture, fat, and water-holding capacity showed explanatory properties in the discriminating analysis (p < 0.05). In addition, strong positive and negative correlations were found among those variables studied. Carcass traits were positively associated, particularly slaughter weight and cold carcass weight (+0.561). Among meat physical traits, pH showed positive correlations with drip loss (+0.490) and pH24 (+0.327), and water-holding capacity was positively associated with cholesterol (+0.434) and negatively associated with collagen (-0.398). According to nutritional traits, fat and ash showed a strong correlation (+0.595), and both were negatively associated with moisture (-0.375 and -0.498, respectively). Strong negative correlations were found as well between meat protein and fat (-0.460) and between collagen and cholesterol (-0.654). Finally, the Mahalanobis distance suggested a clustering pattern based on meat and carcass characteristics that report information about interbreeding and variety proximity. This study establishes a departure point in the development of a tool for breed traceability guaranteeing aimed at enhancing distinguished, local breed-based turkey meat.

Theorising a connectivity mindset in doctoral candidates – using critical mobilities as a point of departure

ABSTRACT This conceptual paper considers doctoral candidate mindset and effective doctoral supervision. I explore mindset through a Critical Mobilities lens to posit two mindsets that candidates inhabit on their doctoral journey: transit and connectivity (Kesselring, (2006). Pioneering mobilities: New patterns of movement and motility in a mobile world. Environment & Planning A, 38(2), 269–279. https://doi.org/10.1068/a37279). I suggest management of doctoral research in the UK and internationally predisposes doctoral candidates and their supervisors to a ‘transit mindset’ which focuses on completion. On the other hand, a ‘connectivity mindset’ of exploration better enables critical and creative thinking. While both mindsets are necessary for the production of a high-quality thesis, a connectivity mindset can be more uncomfortable for both supervisors and doctoral candidates in the context of the neoliberal performance management culture. With the aim of supporting better doctoral research and doctoral experience, the paper theorises three manifestations of connectivity mindset that supervisors may encounter. These are: ‘rhizomic thinking’ which the supervisory team can identify and support in their supervisee; the ‘nomadic space’ which is created between supervisor and supervisee when they share a connectivity mindset; and a ‘third space’ that is entered into by supervisors and supervisees, when a shared connectivity mindset incorporates personal experiences, feelings and needs. The paper concludes with six areas of focus for development of supervisory practice.

The Lutheran Experience in the Ottoman Middle East: Stephan Gerlach (1546–1612) and the History of Lutheran Accommodation

Abstract This article examines what it meant to be Lutheran in the early modern Middle East. Its point of departure is a letter in which Stephan Gerlach, a sixteenth-century Lutheran chaplain to the imperial ambassador in Istanbul, asked his superiors about the type of behaviour that befitted him as a Lutheran. Was he allowed to wear a Turkish turban to see mosques and learn about Islam? Was it permissible for him in exceptional circumstances to accept communion under both kinds from a Roman Catholic monk? Was he allowed to postpone the Sunday sermon to attend Greek Orthodox ceremonies? Reconstructing how sixteenth-century Lutherans who had business in the early modern Middle East tried to resolve such issues not only affords new insights into the Lutheran experience in the Ottoman Empire; it also raises a set of fundamental questions about late sixteenth-century Lutheranism itself. Did Lutherans in this period develop forms of religious accommodation similar to those of early modern Catholics? Did travel in the Eastern Mediterranean demand a more flexible and more fluid form of Lutheranism? Could one even adhere to Lutheranism’s core principles so far away from the place where the movement had first taken root? Through an examination of various Lutheran treatises and travelogues, I show that sixteenth-century Lutheranism did not develop an official policy of accommodation. Instead, Lutheran responses to questions about accommodation, (dis)simulation and conformity were often makeshift and idiosyncratic, because Lutheranism formulated little to no official guidance on the movement as a lived religion.

Performance study of crack width calculation methods according to Eurocodes, fib model codes and the modified tension chord model

AbstractThis article investigates the accuracy of various crack width prediction models and the newly proposed modified tension chord model (MTCM). A large number of experimental crack widths have been collected from the literature, including 203 specimens of reinforced concrete (RC) members subjected to bending and tension. The prediction models are described with upcoming new formulations and database validation. The modeling uncertainty is found by comparing the predicted crack widths against experimental data obtained using a log‐normal distribution. The results show that fib Model Code 2010 and MTCM provide the best crack width predictions of the collected databases; MTCM has the fewest mechanical simplifications of the investigated models and no empirical modifications for fitting towards experimental databases, in contrast to the approaches in Eurocode 2 and Model Code. However, the latter do predict the crack width to a reasonably good extent and are more suited for practical dimensioning than the MTCM. The findings in this article suggest that the MTCM should serve as a point of departure for further development of crack width calculation methods, and that it may have an extensive range of possible applications in the future.

Home as survival: Seeing Queer archival lives

As a teenager in the eighties, French filmmaker Sébastien Lifshitz scoured flea markets for amateur photographs. In 2013, he assembled a book titled The Invisibles comprised of snapshots depicting queer lives. He included a pair of Kodachrome images, which replicate a near-identical domestic scene in the 1960s: two aging women in their bourgeois home sit at a table, embracing as they look at the camera. Taking as a point of departure these personal photographs, this article focuses on two documentaries that queer postwar domesticity: Lifshitz’s The Invisibles (2011) and Magnus Gertten’s Nelly and Nadine (2022). In his film, Lifshitz not only includes postwar snapshots and home movies, but also reinvents the amateur dispositif. He interviews queer aging men and women inside their homes, challenging social exclusion and stigma based on gender nonconformity and aging. In Nelly and Nadine, a sexagenarian named Sylvie retrieves home movies from her attic that uncover a lesbian love story between her grandmother Nelly and a fellow survivor of Ravensbrück named Nadine. Decades later, the centrality of the domestic space and the amateur archive in these two documentaries offers a lesson in seeing the home as survival and unlearning the master narratives of the postwar era.

The Transgression List in Šurpu Tablet IV and Its Sordid Moral Implications

Abstract Modern scholarship has become more attentive to the interrelation between performative and scholastic factors in the production of ancient Near Eastern ritual texts. This article aims to shed light on the compositional processes responsible for the integration of a list of transgressions into Šurpu Tablet 4. This analysis is facilitated by the identification of a close parallel from the Namerimburruda tradition. The comparison of these texts illuminates the subtle manner by which scribe responsible for Šurpu IV appropriated earlier materials to fit the theological and rhetorical aims of the new composition. This focused case study can serve as a point of departure for further research on the flexible roles of interpolated sin lists in ancient Near Eastern literature.
