PENGARUH BANKING RELATIONSHIP TERHADAP KINERJA PERUSAHAAN PADA SEKTOR MANUFAKTUR DI INDONESIA

Penelitian ini bertujuan untuk mengkaji bagaimana hubungan perbankan berpengaruh terhadap kinerja perusahaan manufaktur di Indonesia. Asimetri informasi yang tinggi dapat menyesatkan bank dalam pengambilan keputusan kredit dan menyulitkan kreditor dalam melakukan pengawasan. Pengolahan data dilakukan dengan menggunakan software Eviews 6.10 for windows dengan metode Pooled EGLS : Cross-section weight. Penelitian ini menggunakan teknik pengambilan sampel dengan metode purposive sampling. Obyek yang digunakan dalam penelitian ini adalah perusahaan manufaktur yang terdaftar pada Bursa Efek Indonesia (BEI) yang berjumlah 138 perusahaan. Pengujian dalam penelitian ini menggunakan PER (price earning ratio) untuk melihat kinerja perusahaan. Hasil Penelitian ini menemukan bahwa kinerja perusahaan akan menurun jika hubungan dengan bank meningkat. Jika suatu perusahaan menetapkan hubungan pembiayaan kredit bank jangka pendek, maka kinerja perusahaan akan berkurang. Sebaliknya, jika perusahaan memiliki hubungan pembiayaan kredit jangka panjang yang kuat maka kinerja perusahaan akan meningkat

Fractional integral equations tell us how to impose initial values in fractional differential equations

The goal of this work is to discuss how should we impose initial values in fractional problems to ensure that they have exactly one smooth unique solution, where smooth simply means that the solution lies in a certain suitable space of fractional differentiability. For the sake of simplicity and to show the fundamental ideas behind our arguments, we will do this only for the Riemann-Liouville case of linear equations with constant coefficients. In a few words, we study the natural consequences in fractional differential equations of the already existing results involving existence and uniqueness for their integral analogues, in terms of the Riemann-Liouville fractional integral. Under this scope, we derive naturally several interesting results. One of the most astonishing ones is that a fractional differential equation of order $\beta>0$ with Riemann-Liouville derivatives can demand, in principle, less initial values than $\lceil \beta \rceil$ to have a uniquely determined solution. In fact, if not all the involved derivatives have the same decimal part, the amount of conditions is given by $\lceil \beta - \beta_* \rceil$ where $\beta_*$ is the highest order in the differential equation such that $\beta-\beta_*$ is not an integer

New methods for the study and resolution of equations involving fractional operators and their applications

This main topic of research in this dissertation is Mathematical Analysis and, more specifically, Fractional Calculus. We provide new techniques to study, and sometimes solve, fractional integral equations and fractional differential equations. The first two chapters of this thesis provide the introductory notions to be used in the rest of the research. In the third chapter, we provide an original algorithm to find the unique solution of a linear fractional integral equation of constant coefficients. In the fourth chapter, we apply the previously obtained results to fractional differential equations. In particular, we see their implications in the problem of imposing natural initial conditions in such a way that the existence and uniqueness of solution is guaranteed. In the fifth chapter, we develop some applications based on the aforementioned ideas. In the sixth chapter, we discuss conclusions and possible lines of future work

An extension of the Cartwright-McMullen theorem in fractional calculus for the smooth Stieltjes case

In 1976, Donald Cartwright and John McMullen characterized axiomatically the Riemann-Liouvile fractional integral in a paper that was published in 1978. The motivation for their work was to answer affirmatively to a conjecture stated by J. S. Lew a few years before, in 1972. Essentially, their ``Cartwright-McMullen theorem in fractional calculus'' proved that the Riemann-Liouville fractional integral is the only continuous extension of the usual integral operator to positive real orders, in such a way that the Index Law holds. In this paper, we propose an analogous result for the uniqueness of the extension of the Stieltjes integral operator, in the case of a smooth integrator.Comment: 7 page

A Postcolonial Study of Aboriginal Identity in Tara June Winch’s The Yield

[Abstract] This study aspires to explore the issue of Aboriginal identity in Tara June Winch’s novel The Yield (2019) from a postcolonial point of view. In order to fulfill this main goal, I will focus on four major aspects connected to Aboriginality that are particularly relevant in the novel: language and culture, history and traditions, the importance of returning home in Aboriginal literature and, last but not least, Indigenous peoples and their relationship with the land. The methodologies used to carry out this paper were a previous close reading analysis of The Yield, researching about Aboriginal culture, language and struggles, and studying the history of Australian Aboriginal communities in relation to their identities. After years of being subjected to a colonial empire, the Aboriginal peoples of Australia are still suffering the consequences of a system fueled by white supremacy and imperialism. Stories like The Yield, contribute to Australia’s First Nations being validated and accepted.Traballo fin de grao (UDC.FIL). Inglés: estudios lingüísticos y literarios. Curso 2020/202

NF-κB/IKK Activation by Small Extracellular Vesicles Within the SASP

[Abstract] Cellular senescence plays an important role in different biological and pathological conditions. Senescent cells communicate with their microenvironment through a plethora of soluble factors, metalloproteases and extracellular vesicles (EV). Although much is known about the role that soluble factors play in senescence, the downstream signalling pathways activated by EV in senescence is unknown. To address this, we performed a small molecule inhibitor screen and have identified the IκB kinases IKKε, IKKα and IKKβ as essential for senescence mediated by EV (evSASP). By using pharmacological inhibitors of IKKε, IKKα and IKKβ, in addition to CRISPR/Cas9 targeting their respective genes, we find these pathways are important in mediating senescence. In addition, we find that senescence activation is dependent on canonical NF-κB transcription factors where siRNA targeting p65 prevent senescence. Importantly, these IKK pathways are also relevant to ageing as knockout of IKKA, IKKB and IKKE avoid the activation of senescence. Altogether, these findings open a new potential line of investigation in the field of senescence by targeting the negative effects of the evSASP independent of particular EV contents.AO’s lab is supported by BBSRC (BB/P000223/1) and Bart’s Charity Grant (MGU0497).

Constant Sign Solutions to Linear Fractional Integral Problems and Their Applications to the Monotone Method

This manuscript provides some results concerning the sign of solutions for linear fractional integral equations with constant coefficients. This information is later used to prove the existence of solutions to some nonlinear problems, together with underestimates and overestimates. These results are obtained after applying suitable modifications in the classical process of monotone iterative techniques. Finally, we provide an example where we prove the existence of solutions, and we compute some estimates.This research was partially supported by grant numbers MTM2016-75140-P (AEI/FEDER, UE) and ED431C 2019/02 (GRC Xunta de Galicia)S
