Józef M. Bocheński and the categorial reconstruction of concepts in the Lvov–Warsaw School

In this article, Józef M. Bocheński is presented as a representative of the methodological tendencies of the Lvov–Warsaw School (LWS). Special attention is given to the reconstructive analysis of concepts, the categorial trait of this procedure, and examples of its application by Bocheński. First, some historical and substantial arguments are presented for including Bocheński in the LWS. Secondly, the procedure of the reconstruction of concepts applied in the LWS is characterized. Then the attention turns to the categorial trait of the analysis as indicated by Bocheński. Finally, two examples of Bocheński’s categorial reconstruction of concepts are presented. The article ends with a recapitulation and general remarks.

Flexible working for all? How collective constructions by Austrian employers and employees perpetuate gendered inequalities

Objective: This paper pursues the question as to how extended flexible working possibilities in the labor market are legitimized among employers and employees and whether they have potential to mitigate inequalities. Background: Persistent and increasing gendered inequalities in Austria are reflected in the unequal division of unpaid family work in parental couples and in men’s stable full-time employment while women increasingly work part-time. In recent years, employers have expanded flexible working possibilities for all employees, regardless of their gender, also in leading positions and especially for those with family responsibilities. Method: We conducted six focus groups and 16 semi-structured interviews with employers (n=30) and employees (n=25) from 29 contrasting companies across Austria. An in-depth reconstructive analysis facilitated our exploration of collective notions and concepts associated with flexible work and career opportunities. Results: The respondents constructed part-time and flexible work as a new norm strongly connected to women with (potential) children. At the same time, employers and employees legitimized that these women must be protected from penalties resulting from the ideal worker norm still in force and must be variously supported by employers. However, men – the partners of women they could support by making use of these options and taking over childcare – are not constructed as a target group. Conclusion: In a cultural context such as Austria, family-friendly flexible working opportunities perpetuate rather than level gendered inequalities, as men’s need for those opportunities do not emerge in the constructions. The lack thereof is neither explicitly addressed nor challenged.

Mathematics Teachers and Curriculum: Authors or Actors?

Background: Among the plurality of themes addressed by curricular studies, the nature of decision-making processes involving education professionals has guided some research agendas. Delineated by one of those agendas, this text starts by asking what the participation of teachers in processes involving curriculum is. Objective: To analyse the rationality underlying the involvement of mathematics teachers in the context of curriculum reforms in Brazil and Portugal, presenting a theoretical basis inspired by Jürgen Habermas and its suitability to discuss teachers’ participation as authors or actors of curricula reforms. Design: Reconstructive analysis of rationality according to the Habermasian discursive ethics. Settings and participants: The context of a comparative study that surveys documents and interviews with two managers of a curricular reform project in Portugal and Brazil, respectively. Data collection and analysis: Analysis of the rationality that underlies the discourse present in curriculum documents of the countries involved and interviews. Results: Centralising elements of national curriculum policies do not mean by themselves the homogenisation of curricula, the rationality that underlies how projects predict the participation of teachers express an illusory discursive varnish about “teachers actively participating,” there are spaces of micropolicies with controlled margin of changes that advocate mathematics teachers as builders of policies, but the mechanisms of external regulation contradict this. Conclusions: Historically, in both countries, the educational systems, even expressing a rhetorical discourse on autonomy and flexibility, have remained hostages to the regulation of centralist global policies.

“When You Come Together and Do Everything, It’ll be Better for Everybody”: Exploring Gender Relations Among Two Southeastern Native American Tribes

Prior to the imposition of patriarchal colonial norms, Native American (NA) gender relations were characterized as complementary and egalitarian; however, little research has explored gender relations within NA communities today. This study used a community-based critical ethnography to explore contemporary NA gender relations with a purposive sample of 208 individuals from the “Coastal Tribe” and 228 participants from the “Inland Tribe.” After participant observation, interviews, and focus groups were conducted, a collaborative approach to reconstructive analysis was used to identify themes in the data. Within these communities, gender relations tended to reflect egalitarian and cooperative but gendered norms, and participants provided examples of how tribal members are transcending patriarchal colonialism. Through the lens of the Framework of Historical Oppression, Resilience, and Transcendence, we theorize how these gender norms may protect families from risks associated with historical oppression and promote family resilience with implications for research, practice, and policy.

“She’s the Center of My Life, the One That Keeps My Heart Open”: Roles and Expectations of Native American Women

Historically, Native American (NA) mothers have proven essential to the survival of their families and communities, yet scant research has examined their roles today. Current gender roles in NA communities are influenced by historical oppression (both historic and contemporary forms) that acted to reverse matrilineal gender norms in favor of patriarchy. The present study sought to explore norms and expectations for women among two NA tribes located in the southeastern region of the United States. The framework of Historical Oppression, Resilience and Transcendence (FHORT), Hill-Collins’s concept of “motherwork,” and a framework of reproductive justice were used to frame the study and interpret findings. This critical ethnography included data from field notes, semistructured interviews, and focus groups. Reconstructive analysis, a specific type of thematic qualitative analysis for critical ethnographies, was used to interpret data. Participants from both tribes described themes related to the expectations and roles of mothers. These expectations included themes of (a) mothers as caretakers, (b) mothers as the centers of family and role models, (c) women to prioritize family over economic and educational aspirations, and (d) decolonizing norms for mothers. While historical oppression and patriarchal norms have constrained and regulated expectations for motherhood and the domestic roles of NA women, these findings also highlight how women decolonize these norms and find ways to reclaim their power through their roles as mothers.

Comparing the Efficacy of True-Volume Analysis Using Magnetic Resonance Imaging With Computerized Tomography and Conventional Methods of Evaluation in Cystic Osteochondral Lesions of the Talus: A Pilot Study

Background: Osteochondral lesions of the talus (OLT) often require advanced imaging if they prove to be refractory to preliminary microfracture. Orthopedic surgeons may misinterpret the size and morphology of the OLT when evaluating through conventional methods. The purpose of this study was to evaluate MRI as a modality for calculating true-volumes and compare its utility to that of CT true-volume and conventional methods of measuring lesion size. Methods: With IRB approval, an institutional radiology database was queried for patients with cystic OLT that had undergone and failed microfracture and had compatible CT and MR scans between 2011 and 2016. Five lesions, previously analyzed and described in the literature using CT true-volume, were selected. 10 orthopedic surgeons independently estimated the volume of these 5 OLT via standard MRI. Next, 3D reconstructions were created and morphometric true-volume (MTV) analysis measurements of each OLT were generated. The percent change in volumes from CT and MR was compared based upon MTVs determined from 3D reconstructive analysis. Results: The volume calculated using conventional methods in CT and MR scans grossly overestimated the size by of the OLT by 285-864% and 56-374% respectively when compared to 3D true-volume analysis of those CT and MR scans. Conclusions: This study demonstrates that true-volume is more accurate for calculating lesion size than conventional methods. Additionally, when comparing MRI and CT, thin slice CT true-volume is superior to MRI true-volume. True-volume calculation improves accuracy with CT and MRI and should be recommended for use in revision OLT cases. Levels of Evidence: Level III: Case control study

Origin, Types, and Functioning of Chandeliers with Serpent Arms: From the Netherlands to Lithuania

Summary Chandeliers with serpent arms held at the National Museum of Lithuania and the Lithuanian Art Museum are among the earliest found in Lithuania. Previous efforts to find chandeliers of similar décor in Latvia or Poland while collecting material on lighting fixtures in Lithuania and the neighbouring countries were unsuccessful. Due to that reason, it was thought that the spread of these chandeliers of extraordinary décor was limited to the territory of Lithuania. A closer and more thorough look into collections of Western European museums has revealed that the motif of an elegantly coiled snake on chandelier arms should be related to Hans Rogiers, a founder who worked in Amsterdam in 1598–1638. In the article, the origin of chandeliers with serpent arms in Western Europe and the ways they could have possibly reached Lithuania are traced back for the first time. Specimens that survived or did not survive in Lithuania, their development and problems of dating are analysed. Their functioning space is explored and the subject of their symbolism is addressed. The article aims to present and evaluate the surviving chandeliers with serpent arms in Lithuania. In the research, instruments of formal, comparative, iconographic, and reconstructive analysis were used.

The Role of 3D Reconstruction True-Volume Analysis in Osteochondral Lesions of the Talus: A Case Series

Background: Evaluation and management of osteochondral lesions of the talus (OLTs) often warrant advanced imaging studies, especially in revision or cases with cystic defects. It is possible that orthopedic surgeons may overestimate the size and misinterpret the morphology of OLT from conventional computed tomography (CT), thereby influencing treatment strategies. The purpose of this study was to determine the utility of a novel means to estimate the true-volume of OLTs using 3D reconstructed images and volume analysis. Methods: With Institutional Review Board approval, an institutional radiology database was queried for patients with cystic OLTs that failed previous microfracture, having compatible CT scans and magnetic resonance imaging (MRI) between 2011 and 2016. Fourteen patients met inclusion criteria. Of these, 5 cases were randomly selected for 3D CT reconstruction modeling. Ten orthopedic surgeons independently estimated the volume of these 5 OLTs via standard CT. Then 3D reconstructions were made and morphometric true-volume (MTV) analysis measurements of each OLT were generated. The percent change in volumes from CT were compared to MTVs determined from 3D reconstructive analysis. Results: On average, the volume calculated by conventional CT scanner grossly overestimated the actual size of the OLTs. The volume calculated on conventional CT scanner overestimated the size of OLTs compared to the 3D MTV reconstructed analysis by 285% to 864%. Conclusions: Our results showed that conventional measurements of OLTS with CT grossly overestimated the size of the lesion. The 3D MTV analysis of cystic osteochondral lesions may help clinicians with preoperative planning for graft selection and appropriate volume while avoiding unnecessary costs incurred with overestimation.

Community at the border or the boundaries of community? The case of EU field diplomats

This article contributes to the communities of practice (CoP) literature by focusing on the neglected role of the boundary in constructing community. It takes issue with advocates of International Relations’ (IR) most recent ‘practice turn’ who have overrated inclusive practices of linking to the detriment of taking account of exclusive practices of demarcation. A conceptual turn to the boundary, understood as a ‘site of difference’, highlights how the two sets of practices operate simultaneously in creating shared senses of belonging to a community. The article empirically probes this turn to the boundary by studying how the postmodern community of the European Union (EU) is (re)constructed by EU diplomats in its neighbouring state Ukraine. As a borderland, it symbolises an interstitial zone of high connectivity where the EU’s otherwise latent order is unearthed. A reconstructive analysis of interviews with members of this ‘community of practice’ reveals that they function as ‘boundary workers’ who engage in both boundary-spanning and boundary-drawing practices on an everyday basis. Zooming in on the ‘boundary work’ by EU diplomats exposes the complex process of community-building and thereby helps grasp community as an emergent structure of possibilities whose meaning is contextually mediated by its members’ social experience of the boundary.

AL-SUHRAWARDĪ ON MIRROR VISION AND SUSPENDED IMAGES (MUTHUL MU ʿALLAQA)

The notion of a “World of Images” located somewhere between the immaterial and the material world was a mainstay of eschatological speculation in late medieval Islam. As has been recognised before, the concept was launched by al-Suhrawardī (d. 1191). However, its more properly philosophical underpinnings, in particular the notion of “suspended” images – images which somehow have an objective, rather than just a mental or subjective, status – merit further clarification, which this article attempts to provide. Since the concept of “suspended forms”, while applied to eschatological matters in the last treatise of the Philosophy of Illumination, makes its first appearance in a discussion of mirror vision, I examine in some detail Avicenna's understanding of mirror vision as presented in the Shifāʾ, to which al-Suhrawardī reacts. I then undertake a detailed reconstructive analysis of two paragraphs of the Philosophy of Illumination, paying particular attention to the question of the ontological status of “suspended” or “self-subsistent” images as well as to the idea that mirrors serve, not as loci in which images inhere, but as loci at which they become manifest (singular maẓhar).
