The book addresses the representation of three groups of "others" in Israeli schoolbooks: Holocaust victims, presented as the stateless persecuted Jews "we" might become again if "we" lose control over the second group of "others" - Palestinian Arabs - who are racialized, demonized and Nazified, and presented as "our" potential exterminators. The third group comprises non-European (Mizrahi and Ethiopian) Jews, portrayed as backward people who lack history or culture, requiring constant acculturation by "Western" Israel. Thus, a rhetoric of victimhood and (...) power evolves, and a nationalistic interpretation of the "never again" imperative is inculcated, justifying the Occupation and oppression of Palestinians and the discrimination of non-European Jews. Advocating a multidirectional memory, the book proposes an alternative Hebrew-Arabic, multi-voiced and poly-centered curriculum that would relate the untold accounts of the people whom the pedagogic version of history seeks exclude. Instead of traumatizing and urging vengeance, it will encourage discussion and celebrate diversity and hybridity. (shrink)

AimBased on the Theory of Reasoned Action, we examined whether attitudes of nurses from different ethnic groups, subjective norms, behavioral intentions, assessments of relationships and communication were associated with their perceptions of the quality of perinatal care provided to lesbian women.BackgroundNurses administer healthcare, provide pertinent information and consultation to lesbians from pregnancy planning through birth.IntroductionDuring the past few decades, worldwide, there has been a rise in lesbian-parenting. Despite the changes in Israeli society’s public and legal reality, intolerance and discrimination to (...) the homosexual population is still prevalent in Israel’s healthcare system.MethodsA cross-sectional study conducted between 12/2015-4/2016. Of the 270 nurses approached, 184 completed a self-report anonymous questionnaire.FindingsThis is an important and timely study reflecting nurses’ perceptions of the quality of perinatal care provided to lesbians. The study findings reflect that attitudes, subjective norms, behavioral intentions, assessments of relationships and communication of nurses from different ethnic groups are associated with their perceptions of the quality of perinatal care provided to the lesbians. The hierarchical regression analysis demonstrated that attitudes, subjective norms, behavioral intentions, assessments of relationships and communication of nurses contributed 56% to the variance of nurses’ perception of their own quality of perinatal care.DiscussionTRA conceptualization predicted the quality of care of nurses from different ethnic groups treating lesbians in a perinatal setting.ConclusionTRA provides a useful framework for understanding and predicting the motivational effect of health care personnel with the lesbian population, being at risk for stigmatization and receiving less quality perinatal care.Implications for nursing and heath policyOur findings revealed the importance of formulating a recognized policy in the field of LGBT medicine at the national level. Further training of nurses as to the lesbians’ unique health needs, might improve the nurses’ relationships and communication as well as the quality of perinatal nursing care. (shrink)

Although well established in developed countries, Ethics review boards in the academia, and specifically for social and behavioral sciences (SBS) research, is a relatively new, and still a controversy inducing endeavor. This study explores the establishment and functioning of ERBs in Israeli academia, serving as a case study for the challenges and progress made in ensuring ethical research practices in non-medical related spheres. A purposeful sample of 46 participants was selected, comprising ERB current or past members and SBS researchers, who (...) each interacted extensively with ERB’s evaluation processes. The participants came from all eight research universities of Israel, as well as seven large public and private academic colleges. Open, semi structured In-depth interviews were conducted in order to facilitate a critical reflective stance among the various participants, exploring their experiences, behaviors and the meanings they assign to ERB processes. Our research revealed two major themes. The first is the developmental trajectories in the construction processes of ERBs in Israel, comprised of the following stages: Initiation, expansion, opposition, and acceptance and assimilation. The second was a typology of participation throughout the ERBs’ construction process. Inspired by Merton’s strain theory, this typology includes conformists, ritualists, ideologists, control-freaks, and insurgents. The findings expose a unique perspective into the initiation, establishment, and development of ERBs, which can shed light on the role of ERBs in general, as well as point out how resistance to ERBs, as well as the different reasons for championing them, affected not only ERBs form and their legitimacy, but also their interaction with researchers.

THEOREM 1.

I.e. for no countable L n -theory T, is K n + 1 the class of reducts of the models of T. Theorem 1.2 (Rubin) $(\diamond_{\aleph_1}).^3$ . Let $M \models Q^E x y\varphi(x, y)$ mean that there is $A \subseteq |M|$ such that $E_{A, \varphi} = \{\langle a, b \rangle \mid a, b \in A$ and $M \models \varphi\lbrack a, b\rbrack\}$ is an equivalence relation on A with uncountably many equivalence classes, and such that each equivalence class is uncountable. Let $K^E = \{\langle A, R\rangle\mid \langle A, R\rangle\models \neg Q^Exy R(x, y)\}$ . Then K E is not an ℵ 0 -PC-class in the logic gotten by closing first order logic under the set of quantifiers {Q n ∣ n ∈ ω} which were defined in Theorem 1.1. (shrink)

La Critique de la raison impure rapproche deux auteurs, deux oeuvres, a priori inconciliables : Le Banquet de Platon et Pour en finir avec le jugement de dieu d'Antonin Artaud. On ne peut bien sûr pas savoir si Platon a vraiment douté de ses propres thèses, mais il a probablement eu conscience de l'impasse de la métaphysique, du peu de consistance de la connaissance contemplative au regard de l'évidence des "faits construits" de la connaissance opératoire qui, au lieu de constituer (...) le réel comme sujet absolu, l'appréhende comme objet. Pour sa part, Antonin Artaud ne semble pas avoir douté des siennes, ne saisissant jamais le réel qu'en le reconstruisant, qu'en le recomposant, par la manipulation de quelques prélèvements soigneusement choisis. C'est sur cette base qu'il était possible de réunir Platon et Antonin Artaud, et aussi avec la thématique du scandale : s'il est camouflé, dans Le Banquet, par l'aspect anecdotique et quelque peu bouffon de l'intervention d'Alcibiade, avec ce subterfuge Platon n'affichait pas moins de défiance envers "dieu" qu'Antonin Artaud dans son émission radiophonique interdite d'antenne en 1948."--Page 4 of cover.

Assuming GCH, we prove that for every successor cardinal μ > ω1, there is a superatomic Boolean algebra B such that |B| = 2μ and |Aut B| = μ. Under ◊ω1, the same holds for μ = ω1. This answers Monk's Question 80 in [Mo].

Is our moral cognition “colored” by the language(s) that we speak? Despite the centrality of language to political life and agency, limited attempts have been made thus far in contemporary political philosophy to consider this possibility. We therefore set out to explore the possible influence of linguistic relativity effects on political thinking in linguistically diverse societies. We begin by introducing the facts and fallacies of the “linguistic relativity” principle, and explore the various ways in which they “color,” often covertly, current (...) normative debates. To illustrate this, we focus on two key Rawlsian concepts: the original position and public reason. We then move to consider the resulting epistemic challenges and opportunities facing contemporary multilingual democratic societies in an age of increased mobility, arguing for the consequent imperative of developing political metalinguistic awareness and political extelligence among political scientists, political philosophers, and political actors alike in an irreducibly complex linguistic world.

Contemporary realities of global population movement increasingly bring to the fore the challenge of quality and equitable health provision across language barriers. While this linguistic challenge is not unique to immigration contexts and is likewise shared by health systems responding to the needs of aboriginal peoples and other historical linguistic minorities, the expanding multilingual landscape of receiving societies renders this challenge even more critical, owing to limited or even non‐existing familiarity of modern and often monolingual health systems with the particular (...) needs of new linguistic minorities. The centrality of language to health beliefs, attitudes, practices, cultural scripts, and conceptual frameworks emphasizes its pivotal role in the healthcare process, and consequently in the adverse effects of treatment that is language‐insensitive and unaware. Such an attitude on the part of medical authorities risks considerable epistemic injustice in the form of a (mis)judgement of patients’ intelligence, credibility, and rationality based on the language that they speak and the manner in which they speak it, consequently impacting the quality and equity of care provided. This danger, I argue, may be effectively countered by fostering among the participants in the healthcare process a sense of epistemic humility through greater metalinguistic awareness. Outlining a range of operative steps that can be used to facilitate this. I argue that the reality of language barriers in the healthcare process, while not entirely eliminable, may nevertheless be successfully addressed, in order to mitigate the challenge of quality and equitable healthcare provision in multilingual societies.

Language is central to political philosophy, yet until now there has been little in the way of a common framework capable of bridging disciplines that share an interest in language, power, and ethics. Studies are predominantly carried out in isolated disciplinary silos - notably linguistics, philosophy, political science, public administration, and education. This volume proposes a new vision for understanding the political ethics of language, particularly in linguistically diverse societies, and it establishes the necessary common framework for this field of (...) inquiry: language ethics. Through creative and constructive thinking, Language Ethics considers how to advance our understanding of the human commonalities of moral and linguistic capacities and the challenge of linguistic difference and societal interdependence. The book embraces the longstanding centrality of language to moral reasoning and reinterprets it in a manner that draws on the social and political life of real-world inter- and intralinguistic issues. Contributors to this collection are leading international experts from different disciplines and approaches whose voices add diverse insight to the discourse on ethics and language justice. Exploring social, political, and economic realities, Language Ethics illuminates the complex nexus between ethics and language and highlights the contemporary challenges facing multilingual societies, including the uncertainties, ambiguities, anxieties, and hopes that accompany them.

Boycotts of various types and forms have become in recent years an increasingly common feature of political life. And yet, despite both their ubiquity and clear ethical grounding, they remain to date under-explored in academic philosophy. I examine in this article the question of the ethics of boycotting, using the academic and cultural boycott of Israel as a case study. I propose that the boycott exhibits an intriguing pattern of continuous tension between its own stated principles and its realised practices, (...) and suggest that this tension is not a dysfunction of the boycott but rather a structural feature, which emanates from its primary commitment to the idea of anti-normalisation as an ethical imperative. I explore the complex cross-linguistic political pragmatics of the notion of normalisation, and argue that the commitment to it on the part of the boycott movement, as a group actor, effectively amounts to a capricious form of arbitrary treatment of the boycotted. I then propose that the effective validation of arbitrary treatment constitutes, first, a harm in itself; and, second, that it hinders the capacity of the campaign to draw on and contribute to a general theory of the ethics of boycotting.

Self-sufficient ideographies are rare because they are stifled by the issue of standardization. Similar issues arise with abstract art or drawings created by young children or great apes. We propose that mathematical indices and artificial intelligence can help us decode ideography, and if not to understand its meaning, at least to know that meaning exists.

We present some techniques in c.c.c. forcing, and apply them to prove consistency results concerning the isomorphism and embeddability relations on the family of ℵ 1 -dense sets of real numbers. In this direction we continue the work of Baumgartner [2] who proved the axiom BA stating that every two ℵ 1 -dense subsets of R are isomorphic, is consistent. We e.g. prove Con). Let K H, be the set of order types of ℵ 1 -dense homogeneous subsets of R (...) with the relation of embeddability. We prove that for every finite model L, : Con iff L is a distributive lattice. We prove that it is consistent that the Magidor-Malitz language is not countably compact. We deal with the consistency of certain topological partition theorems. E.g. We prove that MA is consistent with the axiom OCA which says: “If X is a second countable space of power ℵ 1, and { U 0,\h.;, U n−1 } is a cover of D ▪ X x X -} x,x> ¦ x ϵ X } consisting of symmetric open sets, then X can be partitioned into { X i \brvbar; i ϵ ω } such that for every i ϵ ω there is l such that D ⊇ U l ”. We also prove that MA+OCA [xrArr] 2 ℵ 0 = ℵ 2. (shrink)

All efforts undertaken so far to establish peace between Israel and the Palestinians have failed to seriously address the right of return of the Palestinian refugees. This failure stemmed from a conviction that the question of historical justice in general had to be avoided. Since justice is a subjective construct, it was argued, allowing it to become a subject of negotiation would only perpetuate the conflict. However, the experience of these peace efforts has shown that without solving the problem of (...) the Palestinian refugees an agreement cannot be reached. And the problem cannot possibly be solved without addressing the key Palestinian demand on this issue — the right of return. For both sides, the right of return, more than any other issue, touches on the essence of their history since the beginning of the conflict between them, and on their future. The national narrative of each side thus centers on its version of the history of the 1948 Arab-Israeli war, in the course of which the Palestinian refugee problem was created. And each side maintains the fundamental belief that its future national existence hinges on whether, and how, the issue of the right of return is resolved. For the Palestinians, the right of return is an inalienable right that defines their national identity and their struggle for liberation. For Israeli Jews, the right of return is perceived as an existential threat to the Jewish character of their society, if not to its very existence. It is not surprising, therefore, that within each of the two societies a national consensus has been built around this issue and that the position of each society seems to stand in complete opposition to that of the other. However, we argue that a morally and politically sound basis could and should be established for a workable solution and that such a basis can be provided by the notion of "transitional justice." Transitional justice stresses two major steps as necessary for reconciliation between parties involved in an historic conflict: recognition and restitution. Recognition entails revealing the historical truth about the injustices committed and according their victims dignity and respect as rights-bearing human beings. Restitution is meant to alleviate some of the material deprivation suffered by the victims and is also a form of recognition. In the Israeli-Palestinian case, recognition by Israel of the right of return would entail its assumption of responsibility for the uprooting of the majority of Palestinian society in 1948. This would satisfy a demand that has become a fundamental element in Palestinian national identity. Recognition would then enable the two parties to enter negotiations over restitution, in particular the implementation of the right of return. In these negotiations, as many Palestinian political leaders have indicated, the concerns of Israeli Jews with their national identity would be taken into account. Only if the fundamental concerns of the two parties, which center on the issue of the right of return, are met can the road towards reconciliation between them be opened. (shrink)

The notion of solidarity can be said to be premised on shared intention and joint action, particularly when oriented towards questions of social and political justice. Yet conceptions of solidary relations remain surprisingly thin on language, and the ethics of the linguistic practices and mechanisms through which individuals formulate a sufficiently meaningful backdrop necessary for shared intention and joint action. My aim in this article, therefore, is to begin filling this gap, in the form of a general normative account that (...) identifies the multilayered interrelations between solidarity and language, and examines their moral and practical implications. I begin with a brief overview of solidarity and language in the context of normative debates on bounded political communities. I then proceed to offer a more critical account of solidarity and linguistic difference, challenging some of the assumptions underlying its present understanding in that literature. In order to highlight and illustrate that critique, I explore its relevance to the highly political and often overlooked question of solidarity and language loss. I conclude with a brief reflection on the field of political theory and philosophy, asking what theoretical, conceptual and methodological insights may be gained from a closer attention to the language of solidarity in the theoretical and practical pursuit of justice.

_NeuroAnalysis _investigates using the neural network and neural computation models to bridge the divide between psychology, psychoanalysis, and neuroscience when diagnosing mental health disorders and prescribing treatment. Avi Peled builds on Freud's early attempts to explain the neural basis of mental health by introducing neural computation as a bridging science to explain psychiatric disorders. Peled describes the brain as a complex system of interconnected units and goes on to suggest that conscious experience, feelings, and mood are emergent properties (...) arising from these complex organisations. This model describes mental health disorders in terms of perturbation to the optimal brain organisation, and demonstrates how particular disorders can be identified through a specific breakdown pattern of the brain’s organisation. This fresh approach to the diagnosis of psychiatric disorders will interest students, professors, and researchers of psychoanalysis, neuroscience, and their related fields. (shrink)

Undergraduate social work students are exposed to ethical and legal dilemmas during their fieldwork training. This article presents a study that examined these ethical dilemmas in an Israeli sample of undergraduate social work students. 117 students who participated in a course in ethics submitted 31 written presentations of ethical-dilemma analysis. Their oral presentations were recorded and transcribed. Using a qualitative analysis, three major themes emerged: 1. The tension between the duty to maintain client's confidentiality and its violation under certain conditions; (...) 2. The students’ conflict of loyalty toward the client vs. the organization; 3. The question of the clients’ right to self-determination when, in the student's view, this is against their best interests.Our findings point to the vital role of an ethics course in the social work undergraduate curriculum that can enhance students’ knowledge of specific laws relevant to the limits of confidentiality in social work and their ability to analyze ethical dilemmas as future professionals. Furthermore, it is essential to raise awareness in educators and supervisors concerning moral distress that may afflict students coping with ethical dilemmas at this early professional developmental phase.

My key argument will be that by shifting the debate over Jewish emancipation from the plane of theology, where it had been traditionally fought, to the plane of sociology, Marx was able to circumvent one of Bauer's main arguments against emancipating the Jews. Bauer had contended that as a religion of law, not of faith, Judaism was by its very nature a public creed. It was incompatible, therefore, with life in a free state, where religion could only be a private (...) matter. Marx chose to ignore this argument, treat Judaism as no different from Christianity, and focus his discussion on the nature of the state on the one hand and on the role played by the Jews in civil society on the other. This was less than a satisfactory response to Bauer's argument, but it enabled Marx to present a powerful case for emancipation while, at the same time, launching his critique of economic alienation. Thus, the philosophical advances made by Marx in On the Jewish Question were necessitated by, and integrally related to, his commitment to Jewish emancipation. (shrink)

Public debates on linguistic integration as a socially desired outcome often share a prevailing sentiment that newcomers ought to “learn the language.” But the intensity of that sentiment is rarely accompanied by an equally robust understanding of what, precisely, it means in practice. This results in a notion of linguistic integration with an inbuilt tension between a seemingly pragmatic and commonsensical appearance, on the one hand, and a minimal action‐guidance capacity, on the other hand. This paper explores this intriguing tension, (...) and it identifies three moral and practical challenges that this challenge presents to the normative theorizing of the practical ethics of linguistic integration: (1) a predicament of arbitrary treatment; (2) the interpersonal structure of social and linguistic learning; and (3) the affective dimension of linguistic integration.

In this Article I argue that the citizenship status of Israel’s Palestinian citizens has been eroding since the "events" of October 2000 and that, as a result, Israel, within its rpe-1967 borders, may be moving from a form of democracy that has been termed "ethnic democracy" towards a form of non-democratic state that has been termed "ethnocracy." My argument is based primarily on two legal documents: the new Citizenship and Entry into Israel Law, 2003, which denies Palestinian citizens the right (...) to unite with their closest family members who are residents of the Occupied Territories, and the decision of the High Court of Justice that upheld the constitutionality of this law in 2006. Two other developments that seem to support my thesis are analyzed as well: the "events" of October 2000 themselves and the report of the state commission of inquiry that investigated these events, and the plan, advanced by Yvette Lieberman and his political party, "Yisrael Beytenu," to shift the border between Israel and the West Bank westward, depriving tens of thousands of citizen-Palestinians of their Israeli citizenship.

This review, based on analysis of the abstracts of 271 academic publications, critically examines the development of girlhood studies within a specific sociocultural context – Israeli society. By examining one particular context the authors hope to contribute to the discourse on the worldwide evolution of girlhood studies. The following research questions were posed: How did the body of literature on Israeli girls develop over time? What is the distribution of disciplines and topics represented? Who are the girls at the focus (...) of the writing? What are the methodological and paradigmatic approaches adopted? The findings point to the tentative development of a girlhood studies perspective that began in the 1980s and expanded over time, revealing the spread and reclaiming of feminist theoretical tenets as embodied in the study of girls. The review both sheds light on the pace and the manner in which Western feminist ideas spread to a specific local arena, and identifies unique local influences impacting this process. (shrink)

Transmembrane receptor tyrosine kinases that bind to peptide factors transmit essential growth and differentiation signals. A growing list of orphan receptors, of which some are oncogenic, holds the promise that many unknown ligands may be discovered by tracking the corresponding surface molecules. The neu gene (also called erbB‐2 and HER‐2) encodes such a receptor tyrosine kinase whose oncogenic potential is released in the developing rodent nervous system through a point mutation. Amplification and overexpression of neu are thought to contribute to (...) malignancy of certain human adenocarcinomas. The search for soluble factors that interact with the Neu receptor led to the discovery of a 44 kDa glyco‐protein that induces phenotypic differentiation of cultured mammary tumor cells to growth‐arrested and milk‐producing cells. The Neu differentiation factor (NDF or heregulin), however, also acts as a mitogen for epithelial, Schwann and glial cells. Multiple forms of the factor are produced by alternative splicing and their expression is confined predominantly to the central and to the peripheral nervous systems. One identified neuronal function of this family of polypeptides is to control the formation of neuromuscular junctions, but their physiological role in secretory epithelia is still unknown. Other open questions relate to the transmembrane topology of various precursors, the identity of a putative co‐receptor, the possible existence of additional ligands of Neu and the functional significance of the interaction between Neu and at least three highly related receptor tyrosine kinases.

Normative theorizing in language involves a reflective consideration on the role that language plays in the shaping and reshaping of social and political orders. This is a complex endeavor resulting from the complex nature of the politics of language, in which change is constant and often unpredictable, and in which there exist an irreducible tension between linguistic and moral difference, on the one hand, and a need for societal interdependence on the other hand. The theoretical, conceptual, and methodological challenges emanating (...) from these realities suggest the usefulness of an adaptive approach to the normative theorizing of the political life of language.

Several terms encountered in Mesopotamian sources stand for titles of persons who served either in the palace or in the temple and displayed ambiguous gender qualities. Some of these persons, albeit being males, were characterized by feminine traits and were therefore considered by their society to be effeminate. One of the terms related to these gender-ambiguous persons was kulu’u, whose exact meaning has never been fully determined, mainly because of the scarcity of its textual attestations. On several occasions this term (...) is mentioned in contexts expressing scorn and contempt and was thus used as a pejorative expression. This paper aims at elucidating this phenomenon by clarifying the nature of the vague term kulu’u and subsequently the reasons for its use as a derogatory term. (shrink)

A Boolean algebra B that has a well-founded sublattice L which generates B is called a well-generated Boolean algebra. If in addition, L is generated by a complete set of representatives for B , then B is said to be canonically well-generated .Every WG Boolean algebra is superatomic. We construct two basic examples of superatomic non well-generated Boolean algebras. Their cardinal sequences are 1,0,1,1 and 0,0,20,1.Assuming MA , we show that every algebra with one of the cardinal sequences , α<1, (...) λ<20, or 0,20,1,1 is CWG.Assuming CH, or alternatively assuming MA , we determine which cardinal sequences admit only WG Boolean algebras.We find a necessary and sufficient condition for the canonical well-generatedness of algebras whose cardinal sequence has the form , α<1. We conclude that if such an algebra is CWG, then all of its quotients are CWG. We show that the above is not true for general Boolean algebras. We also conclude that if the cardinality of such an algebra is less than the cardinal defined below, then it is CWG. The cardinal is the least cardinality of an unbounded subset of {f f : ω → ω}.We investigate questions concerning embeddability, quotients and subalgebras of WG and CWG Boolean algebras, and construct various counter-examples.

For a complete theory of Boolean algebras T, let MT denote the class of countable models of T. For B1, B2 ∈ MT, let B1 ≤ B2 mean that B1 is elementarily embeddable in B2. Theorem 1. For every complete theory of Boolean algebras T, if T ≠ Tω, then $\langle M_T, \leq\rangle$ is well-quasi-ordered. ■ We define Tω. For a Boolean algebra B, let I(B) be the ideal of all elements of the form a + s such that $B\upharpoonright (...) a$ is an atomic Boolean algebra and $B\upharpoonright s$ is an atomless Boolean algebra. The Tarski derivative of B is defined as follows: B(0) = B and B(n + 1) = B(n)/I(B(n)). Define Tω to be the theory of all Boolean algebras such that for every n ∈ ω, B(n) ≠ {0}. By Tarski [1949], Tω is complete. Recall that $\langle A, \leq\rangle$ is a partial well-quasi-ordering, if it is a partial quasi-ordering and for every $\{a_i\mid i \in \omega\} \subseteq A$ , there are $i < j < \omega$ such that ai ≤ aj. Theorem 2. $\langle M_{T_\omega}, \leq\rangle$ contains a subset M such that the partial orderings $\langle M, \leq \upharpoonright M \rangle$ and $\langle\mathscr{P}(\omega), \subseteq\rangle$ are isomorphic. ■ Let M'0 denote the class of all countable Boolean algebras. For B1, B2 ∈ M'0, let B1 ≤' B2 mean that B1 is embeddable in B2. Remark. $\langle M'_0, \leq'\rangle$ is well-quasi-ordered. ■ This follows from Laver's theorem [1971] that the class of countable linear orderings with the embeddability relation is well-quasi-ordered and the fact that every countable Boolean algebra is isomorphic to a Boolean algebra of a linear ordering.

Let B be a superatomic Boolean algebra (BA). The rank of B (rk(B)), is defined to be the Cantor Bendixon rank of the Stone space of B. If a ∈ B - {0}, then the rank of a in B (rk(a)), is defined to be the rank of the Boolean algebra $B b \upharpoonright a \overset{\mathrm{def}}{=} \{b \in B: b \leq a\}$ . The rank of 0 B is defined to be -1. An element a ∈ B - {0} is (...) a generalized atom $(a \in \widehat{At}(B))$ , if the last nonzero cardinal in the cardinal sequence of B $\upharpoonright$ a is 1. Let a,b $\in\widehat{At}$ (B). We denote a ∼ b, if rk(a) = rk(b) = rk(a · b). A subset H $\subseteq \widehat{At}$ (B) is a complete set of representatives (CSR) for B, if for every a $\in \widehat{At}$ (B) there is a unique h ∈ H such that h ∼ a. Any CSR for B generates B. We say that B is canonically well-generated (CWG), if it has a CSR H such that the sublattice of B generated by H is well-founded. We say that B is well-generated, if it has a well-founded sublattice L such that L generates B. THEOREM 1. Let B be a Boolean algebra with cardinal sequence $\langle\aleph_0: i . If B is CWG, then every subalgebra of B is CWG. A superatomic Boolean algebra B is essentially low (ESL), if it has a countable ideal I such that rk(B/I) ≤ 1. Theorem 1 follows from Theorem 2.9, which is the main result of this work. For an ESL BA B we define a set F B of partial functions from a certain countably infinite set to ω (Definition 2.8). Theorem 2.9 says that if B is an ESL Boolean algebra, then the following are equivalent. (1) Every subalgebra of B is CWG; and (2) F B is bounded. THEOREM 2. If an ESL Boolean algebra is not CWG, then it has a subalgebra which is not well-generated. (shrink)

Figurative drawing is a skill that takes time to learn, and it evolves during different childhood phases that begin with scribbling and end with representational drawing. Between these phases, it is difficult to assess when and how children demonstrate intentions and representativeness in their drawings. The marks produced are increasingly goal-oriented and efficient as the child’s skills progress from scribbles to figurative drawings. Pre-figurative activities provide an opportunity to focus on drawing processes. We applied fourteen metrics to two different datasets (...) (_N_ = 65 and _N_ = 344) to better understand the intentional and representational processes behind drawing, and combined these metrics using principal component analysis (PCA) in different biologically significant dimensions. Three dimensions were identified: efficiency based on spatial metrics, diversity with color metrics, and temporal sequentiality. The metrics at play in each dimension are similar for both datasets, and PCA explains 77% of the variance in both datasets. Gender had no effect, but age influenced all three dimensions differently. These analyses for instance differentiate scribbles by children from those drawn by adults. The three dimensions highlighted by this study provide a better understanding of the emergence of intentions and representativeness in drawings. We discussed the perspectives of such findings in comparative psychology and evolutionary anthropology. (shrink)

Segmentation of post-operative glioblastoma multiforme (GBM) is essential for the planning of Tumor Treating Fields (TTFields) treatment and other clinical applications. Recent methods developed for pre-operative GBM segmentation perform poorly on post-operative GBM MRI scans. In this paper we present a method for the segmentation of GBM in post-operative patients. Our method incorporates an ensemble of segmentation networks and the Kullback–Leibler divergence agreement score in the objective function to estimate the prediction label uncertainty and cope with noisy labels and inter-observer (...) variability. Moreover, our method integrates the surgery type and computes non-tumorous tissue delineation to automatically segment the tumor. We trained and validated our method on a dataset of 340 enhanced T1 MRI scans of patients that were treated with TTFields (270 scans for train and 70 scans for test). For validation, we developed a tool that uses the uncertainty map along with the segmentation result. Our tool allows visualization and fast editing of the tissues to improve the results dependent on user preference. Three physicians reviewed and graded our segmentation and editing tool on 12 different MRI scans. The validation set average (SD) Dice scores were 0.81 (0.11), 0.71 (0.24), 0.64 (0.25), and 0.68 (0.19) for whole-tumor, resection, necrotic-core, and enhancing-tissue, respectively. The physicians rated 72% of the segmented GBMs acceptable for treatment planning or better. Another 22% can be edited manually in a reasonable time to achieve a clinically acceptable result. According to these results, the proposed method for GBM segmentation can be integrated into TTFields treatment planning software in order to shorten the planning process. To conclude, we have extended a state-of-the-art pre-operative GBM segmentation method with surgery-type, anatomical information, and uncertainty visualization to facilitate a clinically viable segmentation of post-operative GBM for TTFields treatment planning.

Developing countries face numerous barriers to conducting effective and efficient ethics reviews of international collaborative research. In addition to potentially overlooking important scientific and ethical considerations, inadequate or insufficiently trained ethics committees may insist on unwarranted changes to protocols that can impair a study's scientific or ethical validity. Moreover, poorly functioning review systems can impose substantial delays on the commencement of research, which needlessly undermine the development of new interventions for urgent medical needs. In response to these concerns, the Drugs (...) for Neglected Diseases Initiative, an independent nonprofit organization founded by a coalition of public sector and international organizations, developed a mechanism to facilitate more effective and efficient host country ethics review for a study of the use of fexinidazole for the treatment of late stage African Trypanosomiasis. The project involved the implementation of a novel ‘pre-review’ process of ethical oversight, conducted by an ad hoc committee of ethics committee representatives from African and European countries, in collaboration with internationally recognized scientific experts. This article examines the process and outcomes of this collaborative process. (shrink)
