This study investigates how Greek professionals formulate upward requests and simultaneously manage rapport and workplace identity within hierarchical exchanges. The data comprise 400 written requests elicited through a discourse–completion task from 100 participants, supplemented by follow-up interviews. Integrating pragmatic perspectives on request mitigation with Spencer-Oatey’s Rapport-Management model and a social constructionist perspective on identity, the analysis reveals a distinctive “direct-yet-mitigated” style: syntactically direct head acts (typically want- or need-statements) various mitigating devices. This mitigation enables speakers to preserve superiors’ face, assert entitlement, and invoke shared corporate goals in a single move. Crucially, rapport work is intertwined with identity construction. Strategic oscillation between deference and entitlement projects four recurrent professional personae: the deferential subordinate, the competent and deserving employee, the cooperative team-player, and the rights-aware negotiator. Speakers shift among these personae to calibrate relational distance, demonstrating that rapport management functions not merely as a politeness calculus but as a resource for dynamic identity performance. This study thus bridges micro-pragmatic choices and macro social meanings, showing how linguistic mitigation safeguards interpersonal harmony while scripting desirable workplace selves. Full article

Fuzzy differential subordinations, a notion taken from fuzzy set theory and used in complex analysis, are the subject of this paper. In this work, we provide an operator and examine the characteristics of meromorphic functions in the punctured open unit disk that are related to a class of complex parameter operators. Complex analysis ideas from geometric function theory are used to derive fuzzy differential subordination conclusions. Due to the compositional structure of the operator, some pertinent classes of admissible functions are studied through the application of fuzzy differential subordination. Full article

In this paper, we derive novel results concerning third-order differential subordinations for meromorphic functions, utilizing a newly defined linear operator that involves the inverse of the Legendre chi function in conjunction with the Mittag-Leffler identity. To establish these results, we introduce several families of admissible functions tailored to this operator and formulate sufficient conditions under which the subordinations hold. Our study presents three fundamental theorems that extend and generalize known results in the literature. Each theorem is accompanied by rigorous proofs and further supported by corollaries and illustrative examples that validate the applicability and sharpness of the derived results. In particular, we highlight special cases and discuss their implications through both analytical evaluations and graphical interpretations, demonstrating the strength and flexibility of our framework. This work contributes meaningfully to the field of geometric function theory by offering new insights into the behavior of third-order differential operators acting on p-valent meromorphic functions. Furthermore, the involvement of the Mittag-Leffler function positions the results within the broader context of fractional calculus, suggesting potential for applications in the mathematical modeling of complex and nonlinear phenomena. We hope this study stimulates further research in related domains. Full article

The Beishan Orogenic Belt, situated along the southern margin of the Central Asian Orogenic Belt, represents a critical tectonic domain that archives the prolonged subduction–accretion processes and Paleo-Asian Ocean closure from the Early Paleozoic to the Mesozoic. Early Permian magmatism, exhibiting the most extensive spatial-temporal distribution in this belt, remains controversial in its geodynamic context: whether it formed in a persistent subduction regime or was associated with mantle plume activity or post-collisional extension within a rift setting. This study presents an integrated analysis of petrology, zircon U-Pb geochronology, in situ Hf isotopes, and whole-rock geochemistry of Early Permian granites from the Tiancang area in the southern Beishan Orogenic Belt, complemented by regional comparative studies. Tiancang granites comprise biotite monzogranite, monzogranite, and syenogranite. Zircon U-Pb dating of four samples yields crystallization ages of 279.3–274.1 Ma. These granites are classified as high-K calc-alkaline to calc-alkaline, metaluminous to weakly peraluminous I-type granites. Geochemical signatures reveal the following: (1) low total rare earth element (REE) concentrations with light REE enrichment ((La/Yb)_N = 3.26–11.39); (2) pronounced negative Eu anomalies (Eu/Eu* = 0.47–0.71) and subordinate Ce anomalies; (3) enrichment in large-ion lithophile elements (LILEs: Rb, Th, U, K) coupled with depletion in high-field-strength elements (HFSEs: Nb, Ta, P, Zr, Ti); (4) zircon ε_Hf(t) values ranging from −10.5 to −0.1, corresponding to Hf crustal model ages (T_DMC) of 1.96–1.30 Ga. These features collectively indicate that the Tiancang granites originated predominantly from partial melting of Paleoproterozoic–Mesoproterozoic crustal sources with variable mantle contributions, followed by extensive fractional crystallization. Regional correlations demonstrate near-synchronous magmatic activity across the southern/northern Beishan and eastern Tianshan Orogenic belts. The widespread Permian granitoids, combined with post-collisional magmatic suites and rift-related stratigraphic sequences, provide compelling evidence for a continental rift setting in the southern Beishan during the Early Permian. This tectonic regime transition likely began with lithospheric delamination after the Late Carboniferous–Early Permian collisional orogeny, which triggered asthenospheric upwelling and crustal thinning. These processes ultimately led to the terminal closure of the Paleo-Asian Ocean’s southern branch, followed by intracontinental evolution. Full article

This article proposes a reading of Marion’s phenomenology from an early text, arguing that the various phenomenological innovations which are introduced in this work are subordinated to the central concept of transcendence. This concept in Marion’s work names the relation between revelation and experience and makes possible the disclosure of a revelatory phenomenon of radical alterity and asymmetry. Reliant on this concept, Marion’s phenomenology dramatically reconfigures the transcendental subject, the phenomenal object, and the horizon as well as their relation to certain phenomena. While Marion’s early text undergoes numerous revisions and reappears in different versions at several junctures in the development of his intervention in phenomenology, this article maintains that his central concept of transcendence retains its primacy in the structural arrangement of his other phenomenological innovations. Additionally, it will be argued that while the concept of transcendence in Marion has often been treated with suspicion by interpreters as obliquely allowing for a theological incursion into Marion’s phenomenology, such discussions generally miss how Marion’s particular construal of transcendence, as the relation between revelation and experience, necessarily allows for an a priori best explained as a theological judgement. Lastly, several questions attendant to this argument will be suggested for further development and investigation. Full article

In 2002, the Justice and Development Party came to power in Turkey, while Recep Tayyip Erdoğan became its leader in 2003, and both have remained in power until today. Initially, Erdoğan had a predominantly Islamist discourse, and in that period, Islam became gradually more visible in public space and foreign relations. However, that Islamist discourse later increasingly gave way to realpolitik due to domestic requirements and international economic and political changes. This article deals with this transition from Islamism to civil religion and secularism during Erdoğan’s power and explores its nature and characteristics as well as the impact on politics. I suggest that while still sometimes making use of an Islamist rhetoric, Erdoğan’s focus in recent years has been more on various secular–sacred items of civil religion, like homeland, nation (as a chosen people), national flag, (sacralized) state, and, additionally, national development. I examine the civil religion Erdoğan advocates by analyzing his official and casual speeches, interviews he gave, and some of the slogans he used. I also suggest that Erdoğan’s transition to civil religion also represents a shift to secularism, as modern civil religions undermine and subordinate established religions to a great extent and also create their own secular sacredness.

In this study, we introduce and explore the properties of the m-leaf function ${\mathcal{Q}}_m$ defined in the open unit disk $\mathbb{D}$, where $m\in \mathbb{N}$, and this function is defined by the relation ${\mathcal{Q}}_m\left(z\right):=1+{\displaystyle \frac{m+1}{m+2}}z+{\displaystyle \frac{1}{m+2}}{z}^{m+1}$. We determine the main geometrical characterization of this function, focusing on its univalency and its sharp bounds for the real and imaginary modulus. Also, we find radius of convexity, and we give a subordination and inclusion result. Using this function, we introduce a new subclass of analytic functions normalized as usual in $\mathbb{D}$ denoted by ${\mathcal{A}}_m^{r,s}$, and an investigation of this class reveals some interesting properties.

Scholars from several disciplines have recently expressed interest in the field of fractional q-calculus based on fractional integrals and derivative operators. This article mathematically applies the fractional q-differential and q-integral operators in geometric function theory. The linear q-derivative operator ${\mathbf{S}}_{\mu ,\delta ,q}^{n,m}$ and subordination are used in this study to define and construct new classes of $\alpha$-convex functions associated with the cardioid domain. Additionally, this paper explores acute inequality problems for newly defined classes ${\mathcal{R}}_q^{\alpha }(a,c,m,L,P),$ of $\alpha$-convex functions in the open unit disc ${\mathcal{U}}_s$, such as initial coefficient bounds, coefficient inequalities, Fekete–Szegö problems, the second Hankel determinants, and logarithmic coefficients. The results presented in this paper are simple to comprehend and demonstrate how current research relates to earlier research. We found all of the estimates, and they are sharp. Full article

The humility at work scale was developed to provide a numeric representation of the humility at work construct, defined as one’s estimate of low to modest self-importance in the act of doing the work itself and in relation to one’s role in doing the work. In prior studies, scores yielded by the scale have shown concurrent validity with measures of predicted union outcomes. In the present study, published and unpublished sample data were used to show convergent-discriminant validity as a demonstration of construct validity stemming from item-content validity. Using principal component analysis, four distinctive item-content domains were identified as interpretable: expressive humility, supportive humility, effective humility, and appreciative humility. Represented as item-subscales, yielded scores were found to show convergent-discriminant validity with scores yielded from measures of constructs thought to be related and unrelated to the humility construct, with the exception of scores yielded by the effective humility subscale. Included are discussion points for detected and undetected scale validity with an eye on scale use in prediction models and construct applications that bear on the experience of work in reference to supervisors and subordinates whether employed as union or nonunion employees and whether employed in union or nonunion work environments.

In this work, we describe the $\mathfrak{q}$-analogue of a multiplier–Ruscheweyh operator of a specific family of linear operators ${\mathfrak{I}}_{\mathfrak{q},\rho }^s(\nu ,\tau )$, and we obtain findings related to geometric function theory (GFT) by utilizing approaches established through subordination and knowledge of $\mathfrak{q}$-calculus operators. By using this operator, we develop generalized classes of quasi-convex and close-to-convex functions in this paper. Additionally, the classes ${\mathfrak{K}}_{\mathfrak{q},\rho }^s(\nu ,\tau )\left(\phi \right)$, ${\mathfrak{Q}}_{\mathfrak{q},\rho }^s(\nu ,\tau )\left(\phi \right)$ are introduced. The invariance of these recently formed classes under the $\mathfrak{q}$-Bernardi integral operator is investigated, along with a number of intriguing inclusion relationships between them. Additionally, several unique situations and the beneficial outcomes of these studies are taken into account. Full article

The Bantustans in South Africa during the Apartheid era engaged in the extension of their territories, as this entailed increased revenue from the Apartheid regime. The latter aimed to concentrate African populations within these Bantustans, which effectively divided them into ‘ethnic’ groups. The Bantustan project, orchestrated by the regime, sought to implement a ‘divide-and-rule’ strategy. The regime was acutely aware that if the African population were to unite, they could pose significant political and security threats; consequently, it was imperative to maintain divisions through the establishment of ‘ethnically’ segregated Bantustans. This study interrogates how the regime enticed Bantustan leaders with territorial extensions to enforce the pseudo-independence and freedom of Africans within these ethnic enclaves, which received financial backing from the regime. As demonstrated in this study, liberation movements accused Bantustan leaders of collaborating with the regime, thereby branding them as ‘stooges’ of the latter. The Bantustan leaders were neither mere dupes nor entirely independent actors; rather, they were constrained to operate within the politically violent confines of the Apartheid system. Their apprehension towards acting against the regime was driven by self-interest. However, by demanding and accepting territorial extensions, they intensified their subordination to the regime. Utilising primary sources alongside secondary interpretations regarding the Bantustans, this study examines the advantages and disadvantages of territorial extensions. It becomes evident that such collaboration undermined the unity of the African populace in their struggle against Apartheid. This study critiques the management of territorial extensions by both the regime and the Bantustan leaders, focusing specifically on the relationships fostered by these extensions, particularly in relation to the TBVC states.

Background/Objective: In nursing practice, differences have been noted between the shared habitus acquired during academic training and professional practices within healthcare systems. In this context, nurses tend to experience an impact on their autonomy due to the ways in which their professional habitus has been established, which, in some way, alters the cultural capital acquired during their academic training. The objective of this study was to identify factors that facilitate and/or limit autonomy in nursing practice based on professional habitus. Method: This research was conducted using a hermeneutic qualitative study framed within a critical approach that incorporated Bourdieu’s theory of fields (habitus, field, and capital). This study included 11 registered nurses working in hospital settings, 17 nursing students, and six university professors. Data collection included 34 sociodemographic forms, 34 individual semi-structured interviews, and five focus group discussions conducted with an interview guide. The collected data were analyzed using an interpretative hermeneutic approach, integrating grounded theory and Bourdieu’s theory of fields, focusing on the concepts of habitus, field, and capital. Results: This study identified a central theme—clarification of the nurse’s role (professional habitus)—alongside three subthemes: (1) strengthening the nursing identity (identity habitus), (2) optimizing nursing education (optimization habitus), and (3) reinforcing professional credibility (validation habitus). Autonomy was found to be influenced by hierarchical structures, power relations, and institutional constraints within the healthcare social field, which led to limitations in the accumulation of nurses’ symbolic capital. Conclusions: The professional habitus of nurses is shaped by various elements within the healthcare social field. This field is constrained by hierarchical structures and factors such as subordination to the hegemonic biomedical discourse and the medical profession, limited recognition of humanized care, institutional restrictions on acknowledging the nursing process, and a lack of solidarity and leadership. These constraints ultimately hinder the accumulation of symbolic and social capital in nursing, leading to a loss of autonomy and hindering professional development. Full article

This study of Hankel and Hermitian Toeplitz determinants is one of the major areas of interest in Geometric function theory and has wide applications in the areas of signal processing and Applied Mathematics. In our present investigations, we define a new subclass of normalized analytic functions $\mathfrak{H}\left(\lambda \right)$$(\lambda \ge 0)$, defined using a subordination relation with the sine function $\mathcal{K}\left(z\right)=1+sinz$. For the class $\mathfrak{H}\left(\lambda \right)$, coefficient estimates, upper and lower bounds for the Hermitian Toeplitz determinants of second and third order are found. In addition, estimates are provided for the second and third-order Hankel determinants for the class $\mathfrak{H}\left(\lambda \right)$. Full article

Recently, several researchers have estimated the Maclaurin coefficients, namely $\left|q_2\right|$ and $\left|q_3\right|,$ and the Fekete–Szegö functional problem of functions belonging to some special subfamilies of analytic functions related to certain polynomials, such as Lucas polynomials, Legendrae polynomials, Chebyshev polynomials, and others. This study obtains the bounds of coefficients $\left|q_2\right|$ and $\left|q_3\right|$, and the Fekete–Szegö functional problem for functions belonging to the comprehensive subfamilies $T(\zeta ,ϵ,\delta )$ and $J(\phi ,\delta )$ of analytic functions in a symmetric domain $\mathbb{U}$, using the imaginary error function subordinate to Euler polynomials. After specializing the parameters used in our main results, a number of new special cases are also obtained. Full article

Ural owls are one of the largest owls in Europe, exhibiting known aggressive behaviour toward other raptors. They are known to interact with nearly all sympatric owls and many diurnal raptors. To summarise these interactions, a literature search was undertaken in the Web of Sciences and Scopus databases using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology as well principal books on owl biology. The search revealed 22 relevant publications that (along with the book data) described the Ural owl’s relations with seven owls and six diurnal raptor species. The Ural owl is subordinate only to the largest predators like golden eagles and eagles, although only its chicks are known to be killed. Contrary to that, the Ural owls shape the distribution of numerous other species, mostly by strong competition (e.g., forcing tawny owls to breed in suboptimal habitats) or by predation (killing smaller owls and diurnal raptors). Their occurrence could be also protective for some species like boreal owls thanks to the removal of intermediate predators. The relations of Ural owls with goshawks are interesting, which seem to live in some balance—temporal avoidance of activity with frequent co-occurrence. Thanks to their association with old-growth forests and their impact on other predators in their territories, Ural owls act as keystone species in mountainous and boreal forests in Europe. Considering this ecosystem service, Ural owls should be effectively protected e.g., by designing forest-management-free zones around their nesting sites. Full article
