When is Cartesian product a Cayley graph?
Authors: Dobson Edward , Hujdurović Ademir , Imrich Wilfried , Ortner Ronald
Published: June 2023

A graph is said to be {\it Cayley} graph if its automorphism group admits a regular subgroup. Automorphisms of the Cartesian product of graphs are well understood, and it is known that Cartesian product of Cayley graphs is a Cayley graph. It is natural to ask the reverse question, namely whether all the factors of Cartesian product that is a Cayley graph have to be Cayley graphs. The main purpose of this paper is to initiate the study of this question.
A generalization of Bondy’s pancyclicity theorem
Authors: Draganić Nemanja , Correia David , Sudakov Benny
Published: June 2023

The \emph{bipartite independence number} of a graph $G$, denoted as $\tilde\alpha(G)$, is the minimal number $k$ such that there exist positive integers $a$ and $b$ with $a+b=k+1$ with the property that for any two sets $A,B\subseteq V(G)$ with $|A|=a$ and $|B|=b$, there is an edge between $A$ and $B$. McDiarmid and Yolov showed that if $\delta(G)\geq\tilde \alpha(G)$ then $G$ is Hamiltonian, extending the famous theorem of Dirac which states that if $\delta(G)\geq |G|/2$ then $G$ is Hamiltonian. In 1973, Bondy showed that, unless $G$ is a complete bipartite graph, Dirac's Hamiltonicity condition also implies pancyclicity, i.e., existence of cycles of all the lengths from $3$ up to $n$. In this paper we show that $\delta(G)\geq\tilde \alpha(G)$ implies that $G$ is pancyclic or that $G=K_{\frac{n}{2},\frac{n}{2}}$, thus extending the result of McDiarmid and Yolov, and generalizing the classic theorem of Bondy.
Tower gaps in multicolour Ramsey numbers
Authors: Dubroff Quentin , Girão António , Hurley Eoin , Yap Corrine
Published: June 2023

Resolving a problem of Conlon, Fox, and R\"{o}dl, we construct a family of hypergraphs with arbitrarily large tower height separation between their $2$-colour and $q$-colour Ramsey numbers. The main lemma underlying this construction is a new variant of the Erd\H{o}s--Hajnal stepping-up lemma for a generalized Ramsey number $r_k(t;q,p)$, which we define as the smallest integer $n$ such that every $q$-colouring of the $k$-sets on $n$ vertices contains a set of $t$ vertices spanning fewer than $p$ colours. Our results provide the first tower-type lower bounds on these numbers.
On the minimum number of inversions to make a digraph k-(arc-)strong
Authors: Duron Julien , Havet Frédéric , Hörsch Florian , Rambaud Clément
Published: June 2023

The {\it inversion} of a set $X$ of vertices in a digraph $D$ consists of reversing the direction of all arcs of $D\langle X\rangle$. We study $\sinv'_k(D)$ (resp. $\sinv_k(D)$) which is the minimum number of inversions needed to transform $D$ into a $k$-arc-strong (resp. $k$-strong) digraph and $\sinv'_k(n) = \max\{\sinv'_k(D) \mid D~\mbox{is a $2k$-edge-connected digraph of order $n$}\}$. We show : (i) $\frac{1}{2} \log (n - k+1) \leq \sinv'_k(n) \leq \log n + 4k -3$ for all $n \in \mathbb{Z}_{\geq 0}$; (ii) for any fixed positive integers $k$ and $t$, deciding whether a given oriented graph $\vec{G}$ satisfies $\sinv'_k(\vec{G}) \leq t$ (resp. $\sinv_k(\vec{G}) \leq t$) is NP-complete ; (iii) if $T$ is a tournament of order at least $2k+1$, then $\sinv'_k(T) \leq \sinv_k(T) \leq 2k$, and $\frac{1}{2}\log(2k+1) \leq \sinv'_k(T) \leq \sinv_k(T)$ for some $T$; (iv) if $T$ is a tournament of order at least $28k-5$ (resp. $14k-3$), then $\sinv_k(T) \leq 1$ (resp. $\sinv_k(T) \leq 6$); (v) for every $\epsilon>0$, there exists $C$ such that $\sinv_k(T) \leq C$ for every tournament $T$ on at least $2k+1 + \epsilon k$ vertices.
Odd-Sunflowers
Authors: Frankl Peter , Pach Janos , Pálvölgyi Dömötör
Published: June 2023

Extending the notion of sunflowers, we call a family of at least two sets an \emph{odd-sunflower} if every element of the underlying set is contained in an odd number of sets or in none of them. It follows from the Erd\H os--Szemer\'edi conjecture, recently proved by %Alweiss, Lovett, Wu, and Zhang, Naslund and Sawin, that there is a constant $\mu <2$ such that every family of subsets of an $n$-element set that contains no odd-sunflower consists of at most $\mu^n$ sets. We construct such families of size at least $1.5021^n$.
Upper bounds on Ramsey numbers for vector spaces over finite fields
Authors: Frederickson Bryce , Yepremyan Liana
Published: June 2023

For $B \subseteq \mathbb F_q^m$, let $\exaff(n,B)$ denote the maximum cardinality of a set $A \subseteq \mathbb F_q^n$ with no subset which is affinely isomorphic to $B$. Furstenberg and Katznelson proved that for any $B \subseteq \mathbb F_q^m$, $\exaff(n,B)=o(q^n)$ as $n \to \infty$. For certain $q$ and $B$, some more precise bounds are known. We connect some of these problems to certain Ramsey-type problems, and obtain some new bounds for the latter. For $s,t \geq 1$, let $R_q(s,t)$ denote the minimum $n$ such that in every red-blue coloring of one-dimensional subspaces of $\mathbb F_q^n$, there is either a red $s$-dimensional subspace of $\mathbb F_q^n$ or a blue $t$-dimensional subspace of $\mathbb F_q^n$. The existence of these numbers is implied by the celebrated theorem of Graham, Leeb, Rothschild. We improve the best known upper bounds on $R_2(2,t)$, $R_3(2,t)$, $R_2(t,t)$, and $R_3(t,t)$.
Extremal number of graphs from geometric shapes
Authors: Gao Jun , Janzer Oliver , Liu Hong , Xu Zixiang
Published: June 2023

We study the Tur\'{a}n problem for highly symmetric bipartite graphs arising from geometric shapes and periodic tilings commonly found in nature. \begin{enumerate} \item The prism $C_{2\ell}^{\square}:=C_{2\ell}\square K_{2}$ is the graph consisting of two vertex disjoint $2\ell$-cycles and a matching pairing the corresponding vertices of these two cycles. We show that for every $\ell\ge 4$, ex$(n,C_{2\ell}^{\square})=\Theta(n^{3/2})$. This resolves a conjecture of He, Li and Feng. \item The hexagonal tiling in honeycomb is one of the most natural structures in the real world. We show that the extremal number of honeycomb graphs has the same order of magnitude as their basic building unit 6-cycles. \item We also consider bipartite graphs from quadrangulations of the cylinder and the torus. We prove near optimal bounds for both configurations. In particular, our method gives a very short proof of a tight upper bound for the extremal number of the 2-dimensional grid, improving a recent result of Brada\v{c}, Janzer, Sudakov and Tomon. \end{enumerate} Our proofs mix several ideas, including shifting embedding schemes, weighted homomorphism and subgraph counts and asymmetric dependent random choice.
The dimension of the feasible region of pattern densities
Authors: Garbe Frederik , Kral Daniel , Malekshahian Alexandru , Penaguiao Raul
Published: June 2023

A classical result of Erd\H os, Lov\'asz and Spencer from the late 1970s asserts that the dimension of the feasible region of homomorphic densities of graphs with at most $k$ vertices in large graphs is equal to the number of connected graphs with at most $k$ vertices. Glebov et al. showed that pattern densities of indecomposable permutations are independent, i.e., the dimension of the feasible region of densities of $k$-patterns is at least the number of non-trivial indecomposable permutations of size at most $k$. We identify a larger set of permutations, which are called Lyndon permutations, whose pattern densities are independent, and show that the dimension of the feasible region of densities of $k$-patterns is equal to the number of non-trivial Lyndon permutations of size at most $k$.
Forcing Generalized Quasirandom Graphs Efficiently
Authors: Grzesik Andrzej , Kráľ Daniel , Pikhurko Oleg
Published: June 2023

We study generalized quasirandom graphs whose vertex set consists of $q$ parts (of not necessarily the same sizes) with edges within each part and between each pair of parts distributed quasirandomly; such graphs correspond to the stochastic block model studied in statistics and network science. Lov\'asz and S\'os showed that the structure of such graphs is forced by homomorphism densities of graphs with at most $(10q)^q+q$ vertices; subsequently, Lov\'asz refined the argument to show that graphs with $4(2q+3)^8$ vertices suffice. Our results imply that the structure of generalized quasirandom graphs with $q\ge 2$ parts is forced by homomorphism densities of graphs with at most $4q^2-q$ vertices, and, if vertices in distinct parts have distinct degrees, then $2q+1$ vertices suffice. The latter improves the bound of $8q-4$ due to Spencer.
Permutation flip processes
Authors: Hladký Jan , Řada Hanka
Published: June 2023

We introduce a broad class of stochastic processes on permutations which we call flip processes. A single step in these processes is given by a local change on a randomly chosen fixed-sized tuple of the domain. We use the theory of permutons to describe the typical evolution of any such flip process $\pi_0,\pi_1,\pi_2,\ldots$ started from any initial permutation $\pi_0\in\SymGr(n)$. More specifically, we construct trajectories $\Phi:\Permuton\times [0,\infty)\rightarrow\Permuton$ in the space of permutons with the property that if $\pi_0$ is close to a permuton $\gamma$ then for any $T>0$ with high probability $\pi_{Tn}$ is close to $\traj{T}{\gamma}$. This view allows to study various questions inspired by dynamical systems.
Rainbow spanning trees in uniformly coloured perturbed graphs
Authors: Katsamaktsis Kyriakos , Letzter Shoham , Sgueglia Amedeo
Published: June 2023

We consider the problem of finding a copy of a rainbow spanning bounded-degree tree in the uniformly edge-coloured randomly perturbed graph. Let $G_0$ be an $n$-vertex graph with minimum degree at least $\delta n$, and let $T$ be a tree on $n$ vertices with maximum degree at most $d$, where $\delta \in (0,1)$ and $d \ge 2$ are constants. We show that there exists $C = C(\delta, d) > 0$ such that, with high probability, if the edges of the union $G_0 \cup \gnp{n}{C/n}$ are uniformly coloured with colours in $[n-1]$, then there is a rainbow copy of $T$. Our result resolves in a strong form a conjecture of Aigner-Horev, Hefetz and Lahiri.
On edge-ordered graphs with linear extremal functions
Authors: Kucheriya Gaurav , Tardos Gábor
Published: June 2023

The systematic study of Tur\'an-type extremal problems for edge-ordered graphs was initiated by Gerbner et al.\ in 2020. Here we characterize connected edge-ordered graphs with linear extremal functions. This characterization is similar in spirit to results of F\"uredi et al.\ (2020) about vertex-ordered and convex geometric graphs.
Tiling Dense Hypergraphs
Authors: Lang Richard
Published: June 2023

There are three essentially necessary conditions for perfect tilings in hypergraphs, which correspond to barriers in space, divisibility and covering. It is natural to ask when these conditions are asymptotically sufficient. Our main result confirms this for hypergraph families that are approximately closed under taking a typical induced subgraph of constant order. As an application, we recover and extend a series of well-known results for perfect tilings in hypergraphs and related settings involving vertex orderings and rainbow structures.
On Hypergraph Supports.
Authors: Raman Rajiv , Singh Karamjeet
Published: June 2023

Let $\mathcal{H}=(X,\mathcal{E})$ be a hypergraph. A support is a graph $Q$ on $X$ such that for each $E\in\mathcal{E}$, the subgraph of $Q$ on the elements in $E$ is connected. We consider hypergraphs defined on a host graph. Given a graph $G=(V,E)$, with $c:V\to\{\R,\B\}$ and a collection of connected subgraphs $\mathcal{H}$ of $G$, a primal support is a graph $Q$ on $\B(V)$ such that for each $H\in \mathcal{H}$, the subgraph $Q[\B(H)]$ on vertices $\B(H)=H\cap c^{-1}(\B)$ is connected. A \emph{dual support} is a graph $Q^*$ on $\mathcal{H}$ s.t. for each $v\in X$, the subgraph $Q^*[\mathcal{H}_v]$ is connected, where $\mathcal{H}_v=\{H\in\mathcal{H}: v\in H\}$. We present sufficient conditions on the host graph and hyperedges so that the resulting support comes from a restricted family. We primarily study two classes of graphs: $(1)$ If the host graph has genus $g$ and the hypergraphs satisfy a topological condition of being \emph{cross-free}, then there is a primal and a dual support of genus at most $g$. $(2)$ If the host graph has treewidth $t$ and the hyperedges satisfy a combinatorial condition of being \emph{non-piercing}, then there exist primal and dual supports of treewidth $O(2^t)$. We show that this exponential blow-up is sometimes necessary. As an intermediate case, we also study the case when the host graph is outerplanar. Finally, we show applications of our results to packing and covering, and coloring problems on geometric hypergraphs.
The structure of Sidon set systems
Authors: Wötzel Maximilian
Published: June 2023

A family $\mathcal{F}\subset 2^G$ of subsets of an abelian group $G$ is a \emph{Sidon system} if the sumsets $A+B$ with $A,B\in \mathcal{F}$ are pairwise distinct. Cilleruelo, Serra and the author previously proved that the maximum size $F_k(n)$ of a Sidon system consisting of $k$-subsets of the first $n$ positive integers satisfies $C_k n^{k-1}\leq F_k(n) \leq \binom{n-1}{k-1}+n-k$ for some constant $C_k$ only depending on $k$. We close the gap by proving an essentially tight structural result that in particular implies $F_k(n)\geq (1-o(1))\binom{n}{k-1}$. We also use this to establish a result about the size of the largest Sidon system in the binomial random family $\binom{[n]}{k}_p$. Extensions to $h$-fold sumsets for any fixed $h\geq 3$ are also obtained.
Minimum non-chromatic-λ-choosable graphs
Authors: Zhu Jialu , Zhu Xuding
Published: June 2023

For a multi-set $\lambda=\{k_1,k_2, \ldots, k_q\}$ of positive integers, let $k_{\lambda} = \sum_{i=1}^q k_i$. A $\lambda$-list assignment of $G$ is a list assignment $L$ of $G$ such that the colour set $\bigcup_{v \in V(G)}L(v)$ can be partitioned into the disjoint union $C_1 \cup C_2 \cup \ldots \cup C_q$ of $q$ sets so that for each $i$ and each vertex $v$ of $G$, $|L(v) \cap C_i| \ge k_i$. We say $G$ is $\lambda$-choosable if $G$ is $L$-colourable for any $\lambda$-list assignment $L$ of $G$. The concept of $\lambda$-choosability puts $ k$-colourability and $k$-choosability in the same framework: If $\lambda = \{k\}$, then $\lambda$-choosability is equivalent to $k$-choosability; if $\lambda$ consists of $k $ copies of $1$, then $\lambda$-choosability is equivalent to $k $-colourability. %We say $G$ is non-chromatic-$\lambda$-choosable if $\chi(G)=k_{\lambda}$ and $G$ is not $\lambda$-choosable. If $G$ is $\lambda$-choosable, then $G$ is $k_{\lambda}$-colourable. On the other hand, there are $k_{\lambda}$-colourable graphs that are not $\lambda$-choosable, provided that $\lambda$ contains an integer larger than $1$. Let $\phi(\lambda)$ be the minimum number of vertices in a $k_{\lambda}$-colourable non-$\lambda$-choosable graph. This paper determines the value of $\phi(\lambda)$ for all $\lambda$.

The Territorial Embeddedness of Novel Labour Integration Policy: Something Old, Something New and Something Borrowed
Authors: Zapata Patrik , Zapata Campos María José
Published: June 2023

This paper examines how local governments can develop new practices in labour integration policy through cross-sector collaborations, and the role of territorial embeddedness in enabling them. The paper is informed by three initiatives for labour market integration of immigrants led by the city district of an urban suburb in the city of Göteborg, in collaboration with actors from the public sector, private sector, and civil society. The paper contributes to research into institutional entrepreneurship and local governments. First, it shows the importance of undermining old, or traditional, practices in labour market integration as part of the process of developing new ones. It also reveals how new practices and organizational forms are added to existing ones, instead of replacing them. Thus, expanding the scope of the public sector in the local labour market integration policy field through elaborative rather than radical change. Second, it reveals the importance to diffuse the new practices, beyond the boundaries of the collaboration that facilitates their creation. Third, the paper illustrates how, rather than hindering, the territorial embeddedness of these collaborative coalitions in marginalized urban suburbs provides access to a wide repertoire of resources, practices, and ideas to facilitate change. Paradoxically, the territorial embeddedness also hampered the diffusion of new practices in the broader field of labour market integration.
On Conceptual Sufficiency
Authors: Davis Benjamin P. ,   Philosophy Documentation Center
Published: June 2023

In this essay, I read Stuart Hall’s idea of “politics without guarantees” as meaning that all concepts are saturated with history and that no use of a concept can prevent it from being co-opted. The contribution of this reading is that it shifts the task of critical theory: if all concepts carry limitations and can be used to advance domination, then critical theorists need not search for pure concepts or worry about how to prevent our concepts from being captured. Instead, our task is to strategically leverage always already imperfect concepts with a view toward shared political goals. For an example of this kind of critical theory, I look to W. E. B. Du Bois’s uses of “human,” “humanity,” and “human rights” in Black Reconstruction, which I suggest were informed by how he came to understand “humanity” in John Brown.

Cultural Diversity Onboard: A Study About Crew Characteristics
Authors: CANIMOĞLU Refik , YILDIRIM Umut
Published: June 2023

Cultural diversity became a significant factor in seafarers’ operational performance onboard. Since ships are operated by multinational crew members, socializing, and understanding foreign cultures became crucial for seafarers working onboard multicultural ships. Diversity management is essential for achieving an effective workforce, as well as making these benefits visible and allowing the organization to leverage them as a competitive advantage. However, apart from its advantages, diversity brought some challenges such as communication errors and cultural misunderstandings. Considering the human element is the primary factor among the maritime accident causations, challenges caused by cultural diversity has the potential to cause a raise in maritime accidents. Crew management onboard multicultural ships should be rigorously carried out to limit unwanted impacts. Our study aims to have a better view on optimal seafarer profile suitable to work onboard ships having multicultural crew members. The prepared questionnaire was administered to interns and officers worked aboard multicultural ships for this purpose, and the findings were evaluated using independent t-test analysis.

Kuduz; Rhabdoviridae familyasından lyssavirusun yol açtığı merkezi sinir sistemini etkileyen ve ölümle sonuçlanan bir hastalıktır (1). Hastalık kontrolü amacıyla, hastalık kaynağının saptanması ve yayılmasının önlenmesi, kuduz şüpheli hayvanlarda karantina önlemlerinin alınması gereklidir. Çeşitli ülkelerde kuduz eradike edilmiştir, ancak bazı ülkelerde kuduz endemik olarak görülmektedir. Dünyada, kedi köpek gibi evcil hayvanlardan bulaş oranının ülkelerde farklı olmasından dolayı, hayvan sahipleriyle birlikte kedi ve köpeklerin seyahatlerinde uygulanan protokoller ve alınan karantina tedbirleri, kuduzun yayılmasını önlemede yüksek öneme sahiptir. Kuduz eradike ülkelerde katı bir biçimde uygulanan bu protokoller, hastalığın sık görüldüğü ülkelerde ne yazık ki yeterli derecede uygulanamamaktadır.

Bu derlemede, ülkelerarası hayvan transferinde uygulanan protokollerinin ve karantina önlemlerinin, ülkelerin kuduz açısından risk düzeylerine ve yapılan farklı uygulamalara göre incelenmesi ve ülkemiz ile karşılaştırılması amaçlanmıştır.
MARK AS NARRATIVE (Plot and Structure of Mark 4,35-8,30)
Authors: Ferry Hartono
Published: June 2023

Every literature consists of Story and Plot, or should I say, series of events. While the Story is about what happened literally, the Plot is more about how the narrator explains what happened. Aristotle alleged that the Plot and Structure were the most important elements in of a Tragedy (Poetics VI,5; VII,1). However, the success of a story also depends on the rendering of Character (Poetics VI,5). Therefore, the study about Characters in  Narrative  Criticism  is  necessary  to  conclude  the  exploration  of  a literature.  Gospel  of  Mark,  as  presented  in  this  paper  is  through  and through a story. Study of plot and structure in it, therefore, is necessary to build the sufficient base for study of character. This research paper is dedicated mainly on plot of the Gospel of Mark, particularly Mark 4,35-8,30. To understand the plot, it is essential to know the style and context of the literature at hand, facts about the author and the setting of the story.
RISET KEAGAMAAN DENGAN PEMBACAAN DEKONSTRUKTIF ALA DERRIDA
Authors: Ferry Hartono
Published: June 2023

Pembacaan Dekonstruktif Derrida, sebagai salah satu kritikan atas tawaran kemapanan strukturalisme, menawarkan pendekatan yang berbeda dalam menganalisis data riset kualitatif. Ketika berbicara tentang riset keagamaan, pembacaan dekonstruktif tidak dapat begitu saja meniadakan banalitas diskusi mengenai sifat apofatis realitas ilahi. Namun, ketika diskusi ditarik ke arah fenomena keagamaan, pembacaan dekonstruktif seperti ikan menemukan kolam yang tenang, tempat ia dapat berenang dengan bebas. Metodologi- metodologi studi keagamaan umum, seperti Fenomenologi, Fungsionalisme, dan Agama Terhayati menekankan kemungkinan untuk menarik dunia metafisis kepada realitas fenomenologis yang dapat diamati dan dipahami. Fenomena-fenomena tersebut, ketika dikaitkan dengan kaidah ruang dan waktu, akan selalu menghasilkan anomali. Keasingan dan penyimpangan dalam fenomena tidak perlu dimusuhi. Dalam pembacaan dekonstruktif, justru unsur pengejut dan pengesan unik dalam fenomena sering menjadi agen kuat untuk memahami suatu obyek pembacaan. Artikel ini bertujuan menunjukkan kedigjayaan pembacaan dekonstruktif sebagai sarana analisis data dalam suatu riset keagamaan. Pembacaan dekonstruktif ini dapat dipakai baik dalam riset kuantitatif maupun riset kualitatif, meskipun harus segera ditambahkan, bahwa riset kuantitatif memiliki handicap-nya tersendiri dalam riset keagamaan. Dalam fenomena keagamaan, jumlah tidak menentukan kebenaran. Justru lebih sering terjadi, fenomena yang unik atau menyimpang, entah itu dalam arti pribadi atau barang mati atau kejadian atau prediksi sekalipun, lebih ‘berkualitas’ dan lebih benar.

Authors: Angelo Luciani Moa Dosi Woda
Published: June 2023

Misteri salib Kristus yang menebus dan menyelamatkan semua manusia, dunia, dan alam semesta, kerap disalahmengerti oleh sebagian orang pada zaman mutakhir ini. Mereka mengklaim bahwa tangisan kematian Yesus di atas kayu salib dianggap sebagai ungkapan putus asa, kutukan dan penderitaan orang yang berdosa. Selain itu, mereka berpendapat bahwa dalam peristiwa salib, terjadi keterpisahan dalam misteri Allah Tritunggal. Tentu saja, pernyataan tersebut tidak benar. Sesungguhnya, Allah menyatakan cinta dan kerahiman-Nya yang sempurna dalam peristiwa salib bagi pembaruan hidup seluruh makhluk ciptaan-Nya.
MELAMPAUI KEBEBASAN: KONSEP KEBEBASAN THOMAS AQUINAS VS KEBEBASAN MODERN
Authors: Simplesius Sandur
Published: June 2023

Kebebasan manusia terungkap dalam suatu pilihan dan pilihan adalah elemen fundamental hidup manusia. Konsep kebebasan memiliki sejarah yang panjang. Hal itu telah ditafsir oleh para pemikir dalam sejarah filsafat dan agama. Para pemikir religius-filosofis tidak memiliki kesatuan pandangan tentang hal ini. Variasi penafasiran tentang kebebasan telah melahirkan cara pandang yang berbeda tentang kebebasan. Ada yang melihatnya sebagai hal yang tidak dapat dipisahkan dari intelek dan kehendak karena kebebasan mengalir dari kedua fakultas ini. Sementara yang lain melihatnya sebagai fakultas dari mana akal budi dan kehendak mengalir. Dalam hal ini kebebasan adalah suatu ekspresi yang paling esensial martabat manusia sehingga melahirkan suatu kebebasan mutlak. Variasi penafsiran ini membawa akibat pada cara pandang tentang hidup dan bagaimana hidup ini dijalankan. Pandangan tentang kebebasan melahirkan pertarungan yang tiada henti antara dua gerakan di dunia modern yaitu pro-life dan pro-choice. Artikel ini menghadirkan suatu penafsiran polemik mengenai kebebasan dari perspektif filsafat moral.

Published: June 2023

The study examined the effect of person-organization fit and organizational citizenship behavior of academic staff working in southwest Nigerian Public Universities. The study adopted a cross-sectional survey research design method. A sample size of 400 employees of the selected universities in South-West Nigeria was chosen from a total population of 8,540 employees. The stratified random sampling technique was adopted for the study. The Work Engagement Scale (WES), Organizational Citizenship Behaviour Checklist (OCBC), Personal Values Scale (PVS), and Value Congruence Scale were used to collect data (VCS). The statistical techniques used for data analysis were descriptive statistics, correlation, and regression analysis. All analysis was done using the statistical package for social science (SPSS) software version 25. Findings showed that value congruence (Coef. = 0.1770, P = 0.010), personality congruence (Coef. = 0.3400, P = 0.000), and work engagement congruence (Coef. = 0.1630, P = 0.001), have significant and positive effects on organizational citizenship behavior. Findings showed that 25.8% of the change in organizational citizenship behaviour was brought about by the dimensions of person-organization fit. The study concluded that person-organization fit has a significant positive effect on the organizational citizenship behaviour of academic staff working in South-Western Public Universities. The study recommended amongst others that qualified individuals with strong organizational fit and moral character are to be chosen for placement in the academic staff cadre structure of universities. The study established that value congruence, personality congruence, and work engagement congruence contribute significantly to organizational citizenship behavior of academic staff in the south-west Nigerian Public Universities.
Racionalidades e epistemologias da prática: reflexões teóricas e metodológicas na/para compreensão das práticas da docência
Authors: Gomes Tiago Pereira , Guedes Neide Cavalcante
Published: June 2023

As práticas educativas têm se configurado como objeto de estudo de pesquisadores educacionais e como tema de diálogos permanentes nos espaços formativos, oportunizando saberes multidimensionais mobilizados por reflexões sobre as intencionalidades dessas ações no campo educativo. Objetivamos discutir sobre as racionalidades e epistemologias da Educação que colaboram para a compreensão das práticas da docência, mediadas pelos pressupostos teóricos e metodológicos que subjazem o desenvolvimento da docência nos diferentes campos que as constituem. Partimos do pressuposto de que os estudos sobre a racionalidade e as epistemologias em Educação colaboram para a compreensão das práticas da docência se configurando como unidades teóricas que alicerçam o saber/fazer prático no contexto da ação educativa e estes ao serem (re)elaborados no processo da reflexão/ação permanente do ensinar e aprender favorecem a construção de saberes múltiplos desencadeando melhorias na qualidade do trabalho docente. Este estudo é um artigo teórico que se originou dos debates reflexivos na disciplina de Prática Educativa do doutorado em Educação. As discussões tecidas no campo teórico-reflexivo no contexto educativo sobre a racionalidade e as epistemologias tornam-se temáticas imprescíndíveis para aprofundarmos e refletirmos acerca das necessidades formativas de professores, sobre os saberes, práticas e profissionalidade docente, haja vista que estes conhecimentos estão subjcentes ao campo de estudo desta pesquisa. Portanto, o compartilhamento de saberes nos momentos dialógicos sobre a prática educativa, ancorados nos estudos teóricos, evidenciaram reflexões permanentes sobre os processos formativos e a ação docente favorecendo a ressignificação de saberes teóricos em relação às racionalidades e às epistemologias da prática.
Questões estratégicas de direitos de gênero, relações sociais paradoxais e políticas afirmativas
Authors: Ruscheinsky Aloisio , Treis Manoella Cará
Published: June 2023

Desigualdades e reconhecimento da diversidade constituem um desafio político e cultural persistente e como tal justifica uma abordagem pelas lentes das ciências sociais. A pesquisa propõe examinar algumas tendências de questões de gênero e suas conexões com políticas públicas. Na metodologia recorremos a bancos de dados e centros de pesquisa sobre questões feministas, realizamos entrevistas e aprimoramos a observação das práticas socioculturais. Nesse sentido, políticas públicas que enfocam a realidade das mulheres são reconhecidas como instituídas, sem esquecer que isso se traduz na existência de lutas sociais históricas. A implementação de políticas visa mitigar as desigualdades de gênero, denominadas ações afirmativas ou resgate da cidadania. Ao abordar a participação na democracia representativa como basilar dos direitos das mulheres, alguns outros tópicos estão relacionados: os direitos inscritos na legislação, a questão do trabalho, as formas de organização coletiva, a permanência da violência de gênero.
Moralité et arbitraire: un regard sur le rapport entre les agents publiques et les bénéficiaires de la Bolsa Família
Authors: Marins Mani Tebet de Azevedo , Melo André de Oliveira Sena
Published: June 2023

Cet article a pour but de contribuer à l’analyse de l’implémentation locale du Programme Bolsa Família. En plus de ses objectifs déclarés, on essaie de comprendre comment les arbitraires, les préjugés et les stigmatisations sont construits autant dans la relation entre les agents publiques et les bénéficiaires que dans le contexte d’interaction des bénéficiaires avec leur voisinage. La base méthodologique repose sur 70 entretiens qui ont été conduits avec trois grands groupes : les familles bénéficiaires (femme responsable légale, conjoint/compagnon et adolescents), les acteurs institutionnels (agents sociaux, agents de santé, enseignants, coordinateur de la Bolsa Família et personnel du bureau d’inscription) et les voisins (non bénéficiaires de la Bolsa Família qui ont pourtant la même situation socio-économique). La recherche a été réalisée dans une périphérie de la région métropolitaine de Rio de Janeiro. On y a parcouru plusieurs lieux fréquentés par les bénéficiaires comme: écoles, postos de saúde, coordination de la Bolsa Família et le secteur d’inscription, Centre de Référence d’Assistance Sociale (CRAS) et restaurant populaire.
Dossier: Urbanismo, política y pandemia en América Latina
Authors: Hita Maria Gabriela , Zárate Vidal Margarita del Carmen
Published: June 2023

Este articulo introduce de modo substancial al dossier "Urbanismo, política y pandemia en América Latina" que reúne una serie de artículos que presentan postales, señales, datos relevantes e indicios del impacto de la pandemia en diversas ciudades, sobre todo de Argentina y Brasil, desde una perspectiva comparativa. Los temas que atraviesan este dossier son los de la gobernabilidad, la política de gestión pública de la pandemia, el manejo de la crisis sanitaria y sus impactos en sectores de salud y de poblaciones más vulnerables en diversos tipos de ciudades, los conflictos entre poderes federales, estatales, regionales y municipales, además del desempeño de diferentes tipos de liderazgos. Además de esta introducción el dossier cuenta con 5 artículos: Di Virgilio y Perelman, sobre Buenos Aires; Torres, Travassos, Moreira y Fernandes, sobre São Paulo; Arantes y Galvão, sobre Salvador; Gledhill, comenta y compara este primer conjunto de artículos, ampliando el alcance analítico para otros países de América Latina; y un último artículo de Marques y Garzón que cierra el dossier con un artículo sobre sistemas de salud en ciudades intermedias amazónicas, el genocidio de poblaciones indígenas y caso de Manaus en el Norte de Brasil. Las principales conclusiones a las que arriban los autores son sobre la existencia de un enorme proceso de segregación espacial y un denominado “racismo ambiental” sobre todo en el caso de Brasil. Entre elementos en común en la región está que zonas periféricas y más pobres fueron las más afectadas, aunque la discusión también abarca otros tipos de cambios en la vida urbana e impactos de la pandemia sobre clases medias. La pandemia puso en evidencia diversas formas de resistencia militante y de resiliencia desde abajo para enfrentar la crisis. Argentina mostró un mejor manejo de la crisis sanitaria, pero en los casos de Brasil, México y otros países del continente, se evidenció la fragilidad de las políticas públicas de gestión de la pandemia y de sus sistemas de salud. Todo ello redundó en la ampliación de las desigualdades ya existentes. Paradójicamente los procesos de urbanización tuvieron dos manifestaciones: por un lado, ampliaron las condiciones de vida de ciertos sectores de la población, pero para el sector mayoritario sólo trajo desindustrialización, precarización y procesos de gentrificación. Al mismo tiempo se produjeron diversas movilizaciones sociales en países como Chile y Colombia, con el aumento creciente de la inconformidad ante la pandemia y el modelo de desarrollo urbano neoliberal. Se sugieren medidas urgentes para enfrentar los problemas: la erradicación de la pobreza, una revisión del modelo de urbanismo, redistribución espacial y una mejora de la sociabilidad y de la movilidad urbana para lograr la inclusión y justicia social. Se cierra el dossier con un nuevo artículo sobre crisis de sistema de salud en Amazonia, con especial énfasis sobre el trágico caso de la falta de oxígeno en Manaus.
Foreign body in the external auditory canal described as a pseudotumor of the middle ear: a case report
Authors: Radivojević Nemanja , Djerić Dragoslava , Dudvarski Zoran , Djorić Igor , Živković Ivana , Šolaja Siniša

Introduction. The aim of this article was to present a case of a foreign body in the external auditory canal described as a pseudotumor of the middle ear, as well as to point out diagnostic and therapeutic aspects of this problem.

Case report. An 8-year-old girl was hospitalized several times in our department due to the surgery of left-sided chronic otitis media. Mastoidectomy and posterior atticotomy were performed during initial hospitalization. Six months later, she was admitted for the second act of the left-sided tympanoplasty. However, two months prior hospitalization, symptoms regarding the right ear appeared: sense of fullness, gradual hearing loss and occasional pain. An otoscopic finding on the right indicated the presence of “tumefaction” in the external auditory canal with a surface that was markedly hyperemic. This pseudotumor was finally interpreted as the foreign body in the external auditory canal.

Conclusion. Foreign bodies in the external auditory canal (EAC) are relatively common in pediatric population. The medical history sometimes is not reliable, and the clinical and radiological interpretation of pseudotumor in the external auditory canal or middle ear must include this possibility in the differential diagnosis as well. Surgical exploration and pathohistological diagnosis are necessary to make a definitive diagnosis and to avoid potential complications.
Legal Consequences of Bankruptcy for Creditors Holding Mortgage Rights and Execution Parate
Authors: Rizalni Kurniawan Aan , Santiago Faisal , Isretno Israhadi Evita
Published: June 2023

The right of the separatist creditor as the holder of the mortgage right is clearly regulated by Law Number 4 of 1996 concerning Mortgage Rights on Land and Objects Related to Land (henceforth referred to as UUHT) Article 20 paragraph (1). In particular, the effect of bankruptcy on mortgage rights appears with the existence of Article 56 paragraph (1) UUK which states that the execution right of a separatist creditor holding mortgage rights against mortgage rights that are in the control of creditors is suspended for a maximum period of 90 days (stay period). The rights of the mortgage holder that have been protected by Article 20 paragraph (1) and Article 21 UUHT are no longer protected if the debtor is declared bankrupt because Article 56 paragraph (1) UUK (stay period) applies which suspends the execution of the mortgage holder for 90 days.
