Vertical integration and profitability of the agrifood industry in an economic crisis context

2015

<p>In a setting of economic and financial crisis, most companies experienced a reduction in their profitability. Thus, our study allows us to identify vertical integration strategies developed by companies to overcome the crisis. This paper is aimed at unveiling the determining factors of the profitability of Spanish agrifood firms, depending on whether they are backwards vertically integrated or not. In order to attain our objective, we implemented a first difference regression model. The main contributions of the article lie in the incorporation of a variable that distinguishes integrated firms from the rest and the separate analysis of the two groups of firms. The results suggest t…

Probabilistic semantics for categorical syllogisms of Figure II

2018

A coherence-based probability semantics for categorical syllogisms of Figure I, which have transitive structures, has been proposed recently (Gilio, Pfeifer, & Sanfilippo [15]). We extend this work by studying Figure II under coherence. Camestres is an example of a Figure II syllogism: from Every P is M and No S is M infer No S is P. We interpret these sentences by suitable conditional probability assessments. Since the probabilistic inference of \(\bar{P}|S\) from the premise set \(\{M|P,\bar{M}|S\}\) is not informative, we add \(p(S|(S \vee P))>0\) as a probabilistic constraint (i.e., an “existential import assumption”) to obtain probabilistic informativeness. We show how to propagate the…

Mathematical models for multicontainer loading problems

2017

Abstract This paper deals with the problem of a distribution company that has to serve its customers by putting first the products on pallets and then loading the pallets onto trucks. We approach the problem by developing and solving integer linear models. We start with basic models, that include the essential features of the problem, such as respecting the dimensions of the truck, and not exceeding the total weight capacity and the maximum weigh capacity on each axle. Then, we add progressively new conditions to consider the weight and volume of pallet bases and to include other desirable features for the solutions to be useful in practice, such as the position of the center of gravity and…

Type II Odontoid Fracture: a case series highlighting the treatment strategies

2019

Background: A type II odontoid fracture, if unstable, can cause spinal cord damage. In this case, it is essential to choose the correct treatment—but the issues of what the correct treatment is and which of the different surgical options is best are quite controversial. In this paper we present strategies for treatment of type II odontoid fracture. Materials and Methods: Thirty consecutive cases of type II odontoid fracture were treated at the Division of Neurosurgery at Villa Sofia Hospital in Palermo (23 cases) and at the Neurosurgical Clinic, University Hospital of Palermo (seven cases), from January 2011 to August 2016. Four patients were treated with external immobilization. Twenty-six…

LA ATENUACIÓN COMO ESTRATEGIA PRAGMÁTICA EN EL MONÓLOGO HUMORÍSTICO SUBVERSIVO

2018

La presente investigación analiza la función de la atenuación en el monólogo humorístico representado por las cómicas españolas de la actualidad. Partimos de la hipótesis de que la atenuación es una de las estrategias discursivas empleadas por las cómicas que emplean un humor subversivo, ya que el uso de la atenuación en un contexto humorístico permite que el hablante pueda tratar, con mayor facilidad, temas o asuntos que en principio podrían resultar controvertidos o problemáticos. Con el objetivo de verificar tal conjetura, este estudio recoge un corpus de 15 monólogos humorísticos representados en salas y teatros españoles durante los años 2017 y 2018. La transcripción y segmentación de …

Marketing Research Regarding the Usage of Online Social Networking Sites by High School Students

2013

This paper aims to present the concept of online social networks (OSN) and its evolution in the world of business as well as several important advantages and disadvantages of using online social networking sites. We are presenting a quantitative research on the main reasons for using online networking sites by high schools students from the several counties of Romania. The authors will present the results of the research which underline: the main activities undertaken by students with this new communication tool, the average number of friends the students have and the selection criteria for them as well as the influence level of OSN sites on the life and activity (school and private) of the…

Nutrire la città: Palermo come possibile laboratorio di innovazione

2022

Alla luce dell’attuale situazione mondiale, aggravata ancora di più dall’attuale situazione politica europea che indubbiamente avrà ripercussioni sul resto del mondo, il tema del cibo, sino a pochi anni fa visto come problema localizzato nei paesi del cosiddetto terzo mondo, sta assumendo una posizione rilevante sia nelle politiche globali sia nell’agenda della pianificazione urbana. Costruire nuove “strategie urbane per il cibo” significa rivedere le politiche del piano lavorando sulla conoscenza e sulla partecipazione riconoscendo come necessario, ancora una volta, il coinvolgimento degli attori locali al fine di arrivare a processi decisionali condivisi ed efficaci. In relazione al sudde…

Fuzzy Investment Portfolio Selection Models Based on Interval Analysis Approach

2012

Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/628295 This paper employs fuzzy set theory to solve the unintuitive problem of the Markowitz mean-variance (MV) portfolio model and extend it to a fuzzy investment portfolio selection model. Our model establishes intervals for expected returns and risk preference, which can take into account investors' different investment appetite and thus can find the optimal resolution for each interval. In the empirical part, we test this model in Chinese stocks investment and find that this model can fulfill different kinds of investors' objectives. Fi…
