Investigating the origin of parthenogenesis and ploidy level in Dahlica fennicella (Lepidoptera: Psychidae)
2013
The theories for the predominance of sexual reproduction predict that parthenogens should have no long-term evolutionary potential due to the lack of genetic recombination, despite short term advantages. Although parthenogenesis is rare among high order animals, true parthenogens can be found in various taxa. The intriguing question of the proliferation and persistence of parthenogenetic species needs investigation. An ideal species for such research is a parthenogenetic mont Dahlica fennicella that appears to be as equally successful as other coexisting sexual species. We investigated whether high ploidy level of D. fennnicella is due to hybridization between closely related sexual species…
Composition of families and subjective economic well-being: an application to Italian context
2011
Using Italian data on Income and Living Conditions for the year 2005, the paper explores empirically whether the determinants of subjective economic well-being (SEW) differ (or not) in four representative typologies of households. By means of a Partial Proportional Ordered Logit Model the subjective economic well-being – proxied by the capacity of households to make ends meet – has been explored. Results highlight the variables acting on SEW, common to each typology, are related both to economic status (specifically, the capacity to pay taxes and to afford housing, clothes and holiday expenditures) and to socio-demographic status (specifically, the work-status and the highest level of educa…
The Prospects for the Social Economy in a Changing World
1997
Even if the ‘social economy’ has traditionally been marginalized and a subordinated form of production within capitalist societies, the economic, social, territorial and environmental problems of the present times have tended to make it a strategic instrument. This is not only because of its qualities as an economic and management instrument, but also because it is an expression of a dynamic and creative civil society. The aim of this paper is to show the potential of the social economy, the way it has been encapsulated during the postwar period and the conditions that now favour its full development. In the face of new challenges, the efficiency criterion, hitherto used to assess alternati…
The measurement of rank mobility
2009
Abstract In this paper we investigate the problem of measuring social mobility when the social status of individuals is given by their rank. In order to sensibly represent the rank mobility of subgroups within a given society, we address the problem in terms of partial permutation matrices which include standard (“global”) matrices as a special case. We first provide a characterization of a partial ordering on partial matrices which, in the standard case of global matrices, coincides with the well-known “concordance” ordering. We then provide a characterization of an index of rank mobility based on partial matrices and show that, in the standard case of comparing global matrices, it is equi…
Measuring consumers’ level of satisfaction for online food shopping during COVID-19 in Italy using POSETs
2021
Abstract The pandemic COVID 19 has upset the economic, social, financial, and general behavioral systems. Global crisis has a large impact overall and related fallouts significantly affect existent structural paradigms in every country and region across the world. In particular, the spread of COVID-19 pandemic has led to having to rethink the way we produce and consume food. Within this global change, a rise in the number of consumers who purchase food products online in order to comply with the rules aimed at limiting the circulation of the virus should be emphasized. Consequently, probably causing a long-term positive effect on m-commerce. The purpose is to elaborate on the index of the s…
Measuring Social Mobility
1993
Abstract The paper considers the ranking of mobility matrices in a simple Markov model of social mobility. The approach is the dynamic counterpart ot the "static" inequality ranking of income distributions by the Lorenz curve. The derived partial ordering is motivated by welfare considerations, is shown to be equivalent to same intuitive mobility concepts, and is used to screen some immobility indices. The equivalence of the ranking with the "permanent income" Lorenz ordering gives support to the claim that this approach is the natural extension of Kolm′s [The optimal production of social justice, in "Public Economics (J. Margolis and H. Guitton, Eds.), MacMillan, London, 1969], Atkinson′s …
The Random-Time Binomial Model
1999
In this paper we study Binomial Models with random time steps. We explain, how calculating values for European and American Call and Put options is straightforward for the Random-Time Binomial Model. We present the conditions to ensure weak-convergence to the Black-Scholes setup and convergence of the values for European and American put options. Differently to the CRR-model the convergence behaviour is extremely smooth in our model. By using extrapolation we therefore achieve order of convergence two. This way it is an efficient tool for pricing purposes in the Black-Scholes setup, since the CRR model and its extrapolations typically achieve order one. Moreover our model allows in a straig…
Aktuālā Eiropas Savienības Tiesas judikatūra Eiropas Aresta ordera lietās
2019
Bakalaura darba “Aktuālā Eiropas Savienības Tiesas judikatūra Eiropas Aresta ordera lietās” mērķis ir izpētīt astoņus nozīmīgus Eiropas Savienības Tiesas spriedumus Eiropas Aresta ordera lietās. Ievērojot minēto, bakalaura darbs sniedz ieskatu Eiropas Savienības Tiesas nesenajos spriedumos, kuros skaidroti Padomes Pamatlēmumā par Eiropas Aresta orderi un par nodošanas procedūrām starp dalībvalstīm ietvertie jēdzieni “tiesas nolēmums” un “tiesu iestāde”, kā arī aplūkoti Pamatlēmumā ietvertie Eiropas Aresta ordera neizpildes pamati un Eiropas Aresta ordera ietekme uz personas pamattiesībām. Darba ietvaros Autore akcentē galvenos problēmjautājumus Eiropas Aresta ordera piemērošanā un analizē s…
Personas izdošana Eiropas Savienībā
2015
Šī bakalaura darba gaitā autors izpētīja izdošanas institūta vēsturisko attīstību, apcietinājuma ordera piemērošanu praksē, kā arī konstatēja un aprakstīja problēmjautājumus, kas radās saistībā ar Eiropas apcietinājuma ordera piemērošanu praksē. Analizējot Eiropas apcietinājuma ordera pielietojumu un tā praksi autors nonāca pie secinājuma, ka ir novērojami problēmjautājumi: 1)ar samērīguma principa nodrošināšanu (no tā izriet, ka pirmkārt, tas prasa daudz resursus no saņemošās valsts, otrkārt, tas negatīvi ietekmē cilvēku dzīvi, kas tika izdoti par nenozīmīgiem pārkāpumiem) 2)ar meklētās personas tiesību nodrošināšanu,( piemēram, persona tiek meklēta izmantojot apcietināšanas orderi, kurš i…
Personas izdošana kā starptautiskās sadarbības veida regulējums Eiropas Savienībā
2017
Jau gadsimtiem ilgi pasaule ir pazinusi noziedzību un tās dažādās izpausmes, līdz ar to cīņa pret to vienmēr ir bijusi valstu prioritāte, lai nodrošinātu drošu vidi tās iedzīvotājām. Tāpat ir zināms, ka noziedzība nepazīst valstu robežas – terorisms, organizētā noziedzība, noziedznieki, kuri cenšoties izvairīties no soda mēģina slēpties citās valstīs, ir visu valstu problēma ar kuru jācīnās kopīgiem spēkiem. Tieši tāpēc aizvien lielāku nozīmi iegūst sasvstarpējā valstu sadarbība. Viens no šādas sadarbības veidiem personas izdošana institūts. Maģistra darba ietvaros darba autore analizējusi regulējumu un aktuālos problēmjautājumus saistībā ar personas izdošanu Eiropas Savienības dalībvalstu …
