Opis:
Several concepts of incomparability of Banach spaces have been considered in the literature, which allow one to describe some of the properties of the product of two Banach spaces as a juxtaposition of the corresponding properties of the factors. In this paper we study the relations between these concepts of incomparability, survey the main results and applications, and state some open problems.

Opis:
We prove a basic property of continuous multilinear mappings between topological vector spaces, from which we derive an easy proof of the fact that a multilinear mapping (and a polynomial) between topological vector spaces is weakly continuous on weakly bounded sets if and only if it is weakly uniformly} continuous on weakly bounded sets. This result was obtained in 1983 by Aron, Hervés and Valdivia for polynomials between Banach spaces, and it also holds if the weak topology is replaced by a coarser one. However, we show that it need not be true for a stronger topology, thus answering a question raised by Aron. As an application of the first result, we prove that a holomorphic mapping ƒ between complex Banach spaces is weakly uniformly continuous on bounded subsets if and only if it admits a factorization of the form f = g∘S, where S is a compact operator and g a holomorphic mapping.

Opis:
Several operational quantities have appeared in the literature characterizing upper semi-Fredholm operators. Here we show that these quantities can be divided into three classes, in such a way that two of them are equivalent if they belong to the same class, and are comparable and not equivalent if they belong to different classes. Moreover, we give a similar classification for operational quantities characterizing lower semi-Fredholm operators.

Opis:
We give several characterizations of the improjective operators, introduced by Tarafdar, and we characterize the inessential operators among the improjective operators. It is an interesting problem whether both classes of operators coincide in general. A positive answer would provide, for example, an intrinsic characterization of the inessential operators. We give several equivalent formulations of this problem and we show that the inessential operators acting between certain pairs of Banach spaces coincide with the improjective operators.

Opis:
The aim of this paper is to present a first dialectometric approach to the geolinguistic distribution of the Romance varieties using a new corpus based on the Atlas Linguistique Roman (ALiR) which is currently being developed at the Centro Ramón Piñeiro para a Investigación en Humanidades. However, the dialectometrization of ALiR will allow us not only to analyze the linguistic distance among the varieties of Romania Antiqua, but also to shed light from a quantitative perspective on several issues that have historically raised controversy. Specifically, this paper deals with the Romance subgrouping of the Catalan language, an issue that has been recently reopened by Radatz (2012).

Opis:
We characterize tauberian operators $T:L_1(μ) → Y$ in terms of the images of disjoint sequences and in terms of the image of the dyadic tree in $L_1[0,1]$. As applications, we show that the class of tauberian operators is stable under small norm perturbations and that its perturbation class coincides with the class of all weakly precompact operators. Moreover, we prove that the second conjugate of a tauberian operator $T:L_1(μ) → Y$ is also tauberian, and the induced operator $T̃: L_1(μ)**/L_1(μ) → Y**/Y$ is an isomorphism into. Also, we show that $L_1(μ)$ embeds isomorphically into the quotient of $L_1(μ)$ by any of its reflexive subspaces.

Opis:
For each S ∈ L(E) (with E a Banach space) the operator R(S) ∈ L(E**/E) is defined by R(S)(x** + E) = S**x** + E(x** ∈ E**). We study mapping properties of the correspondence S → R(S), which provides a representation R of the weak Calkin algebra L(E)/W(E) (here W(E) denotes the weakly compact operators on E). Our results display strongly varying behaviour of R. For instance, there are no non-zero compact operators in Im(R) in the case of $L^1$ and C(0,1), but R(L(E)/W(E)) identifies isometrically with the class of lattice regular operators on $ℓ^2$ for $E = ℓ^2(J)$ (here J is James' space). Accordingly, there is an operator $T ∈ L(ℓ^2(J))$ such that R(T) is invertible but T fails to be invertible modulo $W(ℓ^2(J))$.

Opis:
In this paper, we analyze the competitive and innovative trajectories followed by the canned fish industry in recent times. We base our study on four case studies from the Galician industry in Spain, which comprises the largest share of the European canned fish sector. At least four different innovation patterns are found in the industry. The first pattern is a conservative one where innovation is seen as a risk and therefore maintaining current routines is the chosen option. The second pattern has been defined as “large retailer-dominated” and is followed by companies that have signed exclusive agreements with large retailers, which increasingly determine most of their innovation activities. The third strategy we have defined as “territory-orientated,” since product innovation and incorporation of quality distinctions based on the territory are the main innovation drivers. Finally, we have an “ecological or nature-orientated” innovation strategy where meeting ecological normative requirements is the main innovation driver.

Opis:
This paper studies the changes which have occurred in the Spanish cod fishing industry in the last few years. We also aim to understand the dynamics of industrial change and its relation to institutions, understood here as both formal and informal rules and conventions. Our results suggest that sometimes industries, in order to maintain their competitive position, need something more than incremental changes in their products or in the technologies that they use. As we can see with the Spanish cod fishing industry, major changes are needed which affect the institutional set-up of their production system. Nevertheless, even when major changes happen in the production sphere, this does not mean that major alterations happen in the way companies innovate, i.e. in their innovation system.

Opis:
Islands have always occupied a significant place in literature and have been a source of inspiration for the literary imagination. Fictional islands have existed as either lost paradises, or places where law breaks down under physical hardships and a sense of entrapment and oppression. Islands can be sites of exotic fascination, of cultural exchange and of great social and political upheaval. However, they are more than mere locations since to be in a place implies being bound to that place and appropriating it. That means that the islands narrow boundaries, surrounded by the sea and cut off from mainland, can create bridges between the real and the imaginary as a response to cultural and social anxieties, frequently taking the form of eutopias/dystopias, Edens, Arcadias, Baratarias, metatexts, or cultural crossroads, deeply transforming that particular geographical location. This article is concerned with insularity as a way of interrogating cultural and political practices in the early modern period by looking at the works of Cervantes, Fletcher and Shakespeare where insular relations are characterized by tensions of different sort. The arrival of Prospero and Miranda, Periandro and Auristela (The Trials of Persiles and Segismunda), and Albert and Aminta (The Sea Voyage) to their respective islands take us to a different world, revealing different political and cultural interests and generating multiple perspectives on the shifting relationship between culture, society and power.

Opis:
Universities are one of the key actors within national and regional innovation systems. The nature of university-industry collaboration has changed during the last decades and it varies across countries and regions. Different factors determine the interaction among both organizations, from those related to the industrial structure of the territory to others related to institutional and legal frameworks. In this paper we aim at adding to the understanding of this process based on the comparison between two European regions, Apulia in Italy and Galicia in Spain. Our results show that a progressive transition from a separated to a more integrated approach has occurred at the relational framework affecting universities and industry in both regions. Public policies, particularly from the regional level, have been relevant for promoting university-industry collaboration in Galicia and Apulia. Nevertheless, there still remain cultural and institutional barriers, both from the academy and business sphere, which impede a closer and more fruitful interaction. Besides, the poor innovative culture of traditional industries which dominate in both regions, might affect university-industry interaction. However, an adjustment of the university offer in terms of research is also needed as we observe that collaboration is too much biased by the university scientific and departmental specialization and too little by local and regional industrial specialization.

Opis:
Colorectal cancer (CRC) is the third most commonly diagnosed malignancy and the fourth most deadly cancer in the world for which surgery is the main treatment. Colorectal surgery can be performed through a wide incision in the abdomen or using minimally invasive surgical (MIS) techniques. Some of these techniques include transanal endoscopic microsurgery (TEM ), transanal minimally invasive surgery (TAMIS), transanal total mesorectal excision (TaTME ), and robot-assisted surgery. Studies increasingly confirm that resections using MIS techniques are safe, oncologically equivalent to open surgery and have better short-term results. These surgical approaches are, however, technically demanding and result in a steep learning curve. The main objective of this study is to review the different MIS techniques for colorectal surgery, as well as the training tools and programs designed to achieve the necessary surgical skills. Different training programs in colorectal surgery have been reported for the different surgical techniques analyzed. Most of these programs are based on training tools in the form of surgical simulators, physical and virtual, as well as the use of experimental and cadaveric models. However, structured training programs in minimally invasive colorectal surgery remain scarce, and there should be a consensus on the fundamental training aspects for the various surgical techniques presented. These training programs should ensure that surgeons acquire sufficient surgical skills to be competent in the development of these surgical techniques, improving the quality of the patient’s surgical outcomes.
Rak jelita grubego (RJG) jest trzecim co do częstotliwości rozpoznawania nowotworem złośliwym na świecie, a także czwartą przyczyną zgonów na nowotwory złośliwe. Głównym elementem leczenia RJG jest operacja, którą można wykonać przez rozległe nacięcie powłok lub za pomocą technik minimalnie inwazyjnych. Do tych drugich należą: endoskopowa chirurgia transanalna (TEM ), przezodbytowa chirurgia minimalnie inwazyjna (TAMIS), przezodbytowe całkowite wycięcie mezorektum (TaTME ) oraz chirurgia wspomagana robotowo. Analizy danych potwierdzają, że techniki minimalnie inwazyjne są bezpieczne, równie skuteczne onkologicznie co techniki tradycyjne, a także wiążą się z szybszym powrotem chorych do pełnej sprawności. Ich wspólną cechą są niestety wysokie wymagania techniczne oraz długa krzywa uczenia. W artykule omówione zostały różne techniki minimalnie inwazyjne stosowane w leczeniu RJG oraz metody nauczania tych technik. Jak dotąd opracowano wiele sposobów szkolenia dla różnych technik operacyjnych. Większość opiera się na symulatorach chirurgicznych zarówno rzeczywistych, jak i wirtualnych oraz na wykorzystaniu modeli eksperymentalnych i preparatów z ludzkich zwłok. Niestety usystematyzowane modele szkolenia w minimalnie inwazyjnej chirurgii RJG są nadal rzadkością. Widać wyraźnie potrzebę opracowania konsensusu dotyczącego szkolenia w poszczególnych metodach operacyjnych. Tego rodzaju programy powinny zapewnić uczestniczącym w nich chirurgom zdobycie wiedzy pozwalającej na skuteczne wykonywanie zabiegów w celu zapewnienia pacjentom jak najlepszych efektów leczenia.
