From a (p,2)-Theorem to a Tight (p,q)-Theorem
A family F of sets is said to satisfy the (p,q)-property if among any p sets of F some q have a non-empty intersection. The celebrated (p,q)-theorem of Alon and Kleitman asserts that any family of compact convex sets in R^d that satisfies the (p,q)-property for some q >= d+1, can be pierced by a fixed number (independent on the size of the family) f_d(p,q) of points. The minimum such piercing number is denoted by {HD}_d(p,q). Already in 1957, Hadwiger and Debrunner showed that whenever q > (d-1)/d p+1 the piercing number is {HD}_d(p,q)=p-q+1; no exact values of {HD}_d(p,q) were found ever since.
While for an arbitrary family of compact convex sets in R^d, d >= 2, a (p,2)-property does not imply a bounded piercing number, such bounds were proved for numerous specific families. The best-studied among them is axis-parallel boxes in R^d, and specifically, axis-parallel rectangles in the plane. Wegner (1965) and (independently) Dol'nikov (1972) used a (p,2)-theorem for axis-parallel rectangles to show that {HD}_{rect}(p,q)=p-q+1 holds for all q>sqrt{2p}. These are the only values of q for which {HD}_{rect}(p,q) is known exactly.
In this paper we present a general method which allows using a (p,2)-theorem as a bootstrapping to obtain a tight (p,q)-theorem, for families with Helly number 2, even without assuming that the sets in the family are convex or compact. To demonstrate the strength of this method, we show that {HD}_{d-box}(p,q)=p-q+1 holds for all q > c' log^{d-1} p, and in particular, {HD}_{rect}(p,q)=p-q+1 holds for all q >= 7 log_2 p (compared to q >= sqrt{2p}, obtained by Wegner and Dol'nikov more than 40 years ago).
In addition, for several classes of families, we present improved (p,2)-theorems, some of which can be used as a bootstrapping to obtain tight (p,q)-theorems. In particular, we show that any family F of compact convex sets in R^d with Helly number 2 admits a (p,2)-theorem with piercing number O(p^{2d-1}), and thus, satisfies {HD}_{F}(p,q)=p-q+1 for all q>cp^{1-1/(2d-1)}, for a universal constant c
Writing from the shadowlands: how cross-cultural literature negotiates the legacy of Edward Said
This thesis examines the impact of Edward Said's influential work Orientalism and its legacy in respect of contemporary reading and writing across cultures. It also questions the legitimacy of Said's retrospective stereotyping of early examples of cross-cultural representation in literature as uncompromisingly 'orientalist'.
It is well known that the release of Edward Said's Orientalism in 1978 was responsible for the rise of a range of cultural and critical theories from multiculturalism to postcolonialism. It was a study that not only polarized critics and forced scholars to re-examine orientalist archives, but persuaded creative writers to re-think their ethnographic positions when it came to the literary representations of cultures other than their own. Without detracting from the enormous impact of Said, this thesis isolates gaps and silences in Said that need correcting. Furthermore, there is an element of intransigence, an uncompromising refusal to fine-tune what is essentially a binary discourse of the West and its other in Said's work, that encourages the continued interrogation of power relations but which, because of its very boldness, paradoxically disallows the extent to which the conflict of cultures indeed produced new, hybrid social and cultural formations.
In an attempt to challenge the severity of Said's claim that 'every European, in what he could say about the Orient, was consequently a racist, an imperialist, and almost totally ethnocentric', the thesis examines a number of different discursive contexts in which such a presumption is challenged. Thus while the second chapter discusses the 'traditional' profession-based orientalism of nineteenth-century E. G. Browne, the third considers the anti-imperialism of colonial administrator Leonard Woolf. The fourth chapter provides a reflection on the difficulties of diasporic 'orientalism' through the works of Michael Ondaatje while chapter five demonstrates the effects of the dialogism used by Amitav Ghosh as a defence against 'orientalism'. The thesis concludes with an examination of contemporary writing by Andrea Levy that appositely illustrates the legacy of Said's influence.
While the restrictive parameters of Said's work make it difficult to mount a thorough-going critique of Said, this thesis shows that, indeed, it is within the restraints of these parameters and in the very discourse that Said employs that he traps himself. This study claims that even Said is susceptible to 'orientalist' criticism in that he is as much an 'orientalist' as those at whom he directs his polemic
Pertumbuhan dan Hasil Tanaman Sawi Hijau (Brassica juncea L.) Tumpang Sari Tanaman Chaya (Cnidocolus aconitifolius) dengan Ukuran Tajuk Berbeda
Prayoga, A., Gustiar, F., Marlina, M., Budianta, D., Ammar, M., Susilawati, S. (2023). Growth and yield of mustard (Brassica juncea L.) intercropping chaya plants (Cnidocolus aconitifolius) with different canopy sizes. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 306-317). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Intercropping is planting pattern that cultivates more than one type of plant in a certain unit of time aimed at increasing productivity. This study was conducted to examine the size of the chaya plant crown and the density of mustard plants using an intercropping system in the area of chaya plants (Cnidoscolus aconitifolius) in order to obtain optimal production and growth results. This study was conducted using a split plot design with two factors. The first factor as the main plot of the cultivation system is 3 treatments, namely conventional / monoculture (K0), intercropping on chaya plants with a header diameter of 80 cm (K1), and intercropping on chaya plants with a crown diameter of 120 cm (K2). The second factor is the density or planting distance as a child plot with a planting distance of 15 x 15 cm (P1), and a planting distance of 15 x 20 cm (P2). The data that has been obtained is then analyzed by the Analysis of Variance (ANOVA) method using the R-Studio application. The results showed that the cultivation of mustard greens (B. juncea L.) tosakan variety with intercropping patterns on conventional obtained the best results. But the 80 cm chaya plant canopy is not significantly different from conventional planting patterns so it can be said that the 80 cm chaya canopy is better than the 120 cm chaya plant canopy. The optimal planting distance is a planting distance of 15 x 15 cm because it is not significantly different from a planting distance of 15 x 20 cm in terms of the quality of the results obtained. In terms of quantity, a planting distance of 15 x 15 cm will produce more production results than a planting distance of 15 x 20 cm. So it can be concluded that the cultivation of mustard greens (B. juncea L.) varieties of intercropping chaya plants (Cnidoscolus aconitifolius) can be done on the chaya crown 80 cm and with a planting distance of 15x15 cm
De proxies a partners : las vinculaciones entre actores domésticos y externos en el Líbano. El caso de los partidos Hezbolá y Movimiento del Futuro (2005-2022)
La presente tesis doctoral se propone analizar la compleja relación entre las representaciones
políticas domésticas de la comunidad musulmana libanesa, específicamente Hezbolá y el
Movimiento del Futuro, y su vinculación con actores regionales externos como Irán y Arabia
Saudita. Para ello, se caracterizará el funcionamiento del sistema político libanés, su mecanismo
de representación y la dinámica de enfrentamiento intersectario que se desarrolla en este
contexto. Además, se analizarán y compararán las estrategias de los poderes regionales en su
interacción con el Líbano y entre sí, con el objetivo de entender cómo estos vínculos moldean las
dinámicas geopolíticas en la región. El estudio se centrará en examinar las dinámicas
intermésticas en el Líbano durante las crisis locales que ocurrieron entre 2005 y 2022, buscando
identificar patrones de cooperación y conflicto, y su impacto en la estabilidad política del país y
la agenda regional.
La hipótesis central sostiene que el Líbano, debido a sus fronteras porosas y un Estado central
débil, está atrapado en una compleja trama interméstica donde no solo influyen las rivalidades
intercomunales, sino también la coyuntura regional. Los actores domésticos libaneses no son
simplemente peones de los poderes regionales, sino partners activos en el terreno local de estos
stakeholders externos.
Finalmente, la tesis concluye que el surgimiento y el posterior agravamiento de las crisis
políticas coinciden con el deterioro de la situación de seguridad en la región. En Arabia Saudita
predominó una estrategia orientada a aumentar la seguridad y control en su entorno, ejerciendo
presión excesiva sobre el Movimiento del Futuro para lograr resultados beneficiosos para sus
intereses. Por su parte, Irán también buscó expandir su influencia y seguridad, pero apoyándose
de manera virtuosa en sus socios, siendo Hezbolá su principal aliado en el caso libanés. Las crisis
que se sucedieron entre 2005 y 2022 no pudieron resolverse de manera duradera debido a la falta
de un poder o consorcio de poderes externos capaz de imponer o acompañar un acuerdo entre las
representaciones políticas de las sectas libanesas en disputa.This doctoral thesis aims to analyze the complex relationship between the domestic political
representations of the Lebanese Muslim community, specifically Hezbollah and the Future
Movement, and their linkage with external regional actors such as Iran and Saudi Arabia. To this
end, the functioning of the Lebanese political system, its mechanism of representation and the
dynamics of intersectarian confrontation that unfold in this context will be characterized. In
addition, the strategies of regional powers in their interaction with Lebanon and with each other
will be analyzed and compared, with the aim of understanding how these linkages shape
geopolitical dynamics in the region. The study will focus on examining intermestic dynamics in
Lebanon during the local crises that occurred between 2005 and 2022, seeking to identify
patterns of cooperation and conflict, and their impact on the country's political stability and
regional agenda.
The central hypothesis holds that Lebanon, due to its porous borders and a weak central state, is
caught in a complex intermestic web influenced not only by intercommunal rivalries, but also by
the regional conjuncture. Lebanese domestic actors are not simply pawns of regional powers, but
active partners on the local terrain of these external stakeholders.
Finally, the thesis concludes that the emergence and subsequent aggravation of political crises
coincided with the deterioration of the security situation in the region. In Saudi Arabia, a strategy
aimed at increasing security and control in its environment prevailed, exerting excessive pressure
on the Future Movement to achieve results beneficial to its interests. Iran, for its part, also sought
to expand its influence and security, but with virtuous support from its partners, Hezbollah being
its main ally in the Lebanese case. The crises that occurred between 2005 and 2022 could not be
resolved in a lasting manner due to the lack of an external power or consortium of powers
capable of imposing or accompanying an agreement between the political representations of the
Lebanese sects in dispute.Fil: Chaya, Said. Universidad Nacional de Rosario. Facultad de Ciencia Política Y Relaciones Internacionales; Argentina
What said the economic theory about Portugal. Another approach
With this work we try to analyse the agglomeration process in the Portuguese regions, using the New Economic Geography models. This work aims to test, also, the Verdoorn Law, with the alternative specifications of (1)Kaldor (1966), for the 28 NUTS III Portuguese in the period 1995 to 1999. It is intended to test the alternative interpretation of (2)Rowthorn (1975). With this study we want, also, to test the Verdoorn´s Law at a regional and a sectoral levels (NUTs II) for the period 1995-1999. The importance of some additional variables in the original specification of Verdoorn´s Law is yet tested, such as, trade flows, capital accumulation and labour concentration. This study analyses, also, through cross-section estimation methods, the influence of spatial effects in productivity in the NUTs III economic sectors of mainland Portugal from 1995 to 1999, considering the Verdoorn relationship. The aim of this paper is, yet, to present a contribution, with panel data, to the analysis of absolute convergence and conditional of the sectoral productivity at regional level (from 1995 to 1999). The structural variables used in the analysis of conditional convergence is the ratio of capital/output, the flow of goods/output and location ratio.new economic geography; Verdoorn law; convergence; cross-section and panel data; Portuguese regions
What said the new economic geography about Portugal? An alternative approach
With this work we try to analyse the agglomeration process in Portugal, using the New Economic Geography models, in a linear and in a non linear way. In a non linear way, of referring, as summary conclusion, that with this work the existence of increasing returns to scale and low transport cost, in the Portuguese regions, was proven and, because this, the existence of agglomeration in Portugal. We pretend, also, in a linear way to explain the complementarily of clustering models, associated with the New Economic Geography, and polarization associated with the Keynesian tradition. As a summary conclusion, we can say which the agglomeration process shows some signs of concentration in Lisboa e Vale do Tejo and the productivity factor significantly improves the results that explain the regional clustering in Portugal. The aim of this paper is to analyze, yet, the relationship between the regional industry clustering and the demand for labor by companies in Portugal. Again, the results are consistent with the theoretical developments of the New Economic Geography, namely the demand for labor is greater where transport costs are lower and where there is a strong links "backward and forward" and strong economies of agglomeration.new economic geography; linear and non linear models; Portuguese regions
