Types of big data and designs of evaluation research
No full textThe use of big data can represent a valuable way to inspire decision making at all level of public administration and governments in a time of scarce resources. Nevertheless, new digital data have not deployed their potential in the public arena as they did in the corporations. One reason is that there is still little knowledge about what kind of data can be usefully managed, at what policy level they are really demanded, how they are collected, organized, integrated and interrogated, by whom and for what purposes. There is therefore the need to show how to apply big data to policy evaluation and research. According to a typology of big data (Aragona, 2016) five examples of big data research are presented, in order to show some principal opportunities and challenges that these data offer to policy making and evaluation

Capitolo 4 - Sintetizzare e confrontare le distribuzioni: i valori di disuguaglianza.
No full textIn questo capitolo s’illustrano alcuni strumenti utili a descrivere e confrontare le distribuzioni di differenti variabili. Per iniziare, s’introducono gli indici di disuguaglianza, valori caratteristici che misurano l’attitudine di un fenomeno ad assumere modalità differenti. I diversi indici sono analizzati nel dettaglio e classificati in base al tipo di variabile cui sono applicabili. S’include anche una misura specifica per caratteri trasferibili: la concentrazione. S’introduce, poi, il box plot, un importante grafico per la rappresentazione delle principali caratteristiche
di una distribuzione. Successivamente, si passa alla definizione dei concetti di simmetria e curtosi per valutare la forma di una distribuzione. Il capitolo si conclude con alcune tecniche per operare confronti basilari tra variabili: rapporti statistici, variazioni e numeri indice.
Obiettivo del capitolo è far comprendere l’importanza che l’analisi della variabilità ha sulla sintesi della distribuzione di una variabile, indirizzando alla scelta della migliore tecnica
New Data science: the Sociological Point of View
No full textThe objective of this chapter is to introduce the contribution that, apart from post-positivism, other sociological paradigms, such as interpretivism and social constructionism, may give to the development of research and thinking about da-ta science in social research. These two paradigms have theoretical and methodo-logical beliefs that seem unfitted to interpret the data revolution era because they are focused on individuals, versthen and sense of action and have been usually associated to qualitative research. But they may be of great help in addressing the future of new data research in our discipline, especially on two important aspects. Firstly, on how objective new data are and, furthermore, on the role of knowledge in new data use and construction

Psychopathology, body uneasiness and self-identity in patients with non-BED obesity compared to healthy controls
No full textIntroduction: Obesity represents a major public health problem associated with medical and psychological impairment. Obesity is frequently studied with Binge Eating Disorder (BED) comorbidity. Less evidence is available for non-BED obesity, in spite of its correlation with psychological impairment and body image disturbance. In this study, we explored psychopathological features, eating behaviors, body image disturbance and self-identity impairment in patients with obesity and a control group. In patients, we also studied the relation between specific eating/body features and psychopathological symptoms. Finally, we explored the latent factorial structure that describes these features. Material and methods: The clinical sample was composed by twenty patients suffering from obesity without BED (16 females). The control group included twenty-eight healthy and normal-weight subjects (20 females) enrolled from the general population. All participants underwent a clinical interview and filled out questionnaires about body image and psychopathological symptoms.
Statistics: The Student t test was applied to compare obese patients and healthy controls in all psychological dimensions. In the clinical sample, gender differences were tested through multivariate analyses of variance (MANOVA). Then, correlational analyses explored the relation between specific eating/body features and psychopathological symptoms. Lastly, a principal-components factor analysis was performed to explore the existence of a latent factorial structure emerging from assessment evaluation in obese population.
Results: Obese patients reported significantly higher scores than healthy controls in several psychopathological dimensions, i.e. Somatization, Obsessive-Compulsive, Depression, Hostility, Phobic Anxiety, and Psychoticism. Patients also reported higher body uneasiness and self-identity impairment resulting from some scores on Body Uneasiness Test and Identity and Eating Disorders questionnaire. Avoidant behaviours were more frequently reported in men whereas women reported higher body distress/dissatisfaction. In the clinical sample the questionnaires were correlated and a three-factor structure emerged: “Weight and body control”, “Weakness of Self-Identity”, and “Psychopathological distress”.
Discussion: The present study found that obese patients might present several disturbances in body image, self- perception and general psychopathological distress. Clinicians should be aware of these issues to improve therapeutic strategy in the treatment of obesity
Stress come via di consapevolezza, creatività e guarigione: descrizione di un caso clinico
No full textLo stress è un meccanismo biologico complesso necessario all’attivazione dell’organismo per un adattamento ottimale nel sistema socio-culturale di riferimento. Lo squilibrio di questo sistema adattativo è fonte di uno dei principali disagi della società moderna. Trovare qualcuno che non ne soffre è molto raro: infatti per la scelta dei soggetti di controllo nel nostro studio sullo stress (Aragona & Aragona 2009) siamo dovuti risalire alla casistica storica degli anni ’70. I meccanismi biologici coinvolti sono stati ampiamente descritti nel nostro volume (Aragona & Aragona 2009) e sinteticamente possono essere ricondotti all’attivazione/disattivazione de sistema PNEI (Psico-Neuro-Endocrino-Immuntario) degli assi neuroendocrini ipotalamo-ipofisari e del Sistema Nervoso Autonomo (simpatico e parasimpatico) che preparano l’organismo all’adattamento, il tutto sotto il controllo di varie aree sovraipotalamiche del sistema limbico e corticali ed espresso da manifestazioni emozionali
A modular idealizer chain and unrefinability of partitions with repeated parts
Full text linkRecently Aragona et al. have introduced a chain of normalizers in a Sylow 2-subgroup of Sym(2^n), starting from an elementary abelian regular subgroup. They have shown that the indices of consecutive groups in the chain depend on the number of partitions into distinct parts and have given a description, by means of rigid commutators, of the first n − 2 terms in the chain. Moreover, they proved that the (n − 1)-th term of the chain is described by means of rigid commutators corresponding to unrefinable partitions into distinct parts. Although the mentioned chain can be defined in a Sylow p-subgroup of Sym(p^n), for p > 2 computing
the chain of normalizers becomes a challenging task, in the absence of a suitable notion of rigid commutators. This problem is addressed here from an alternative point of view. We propose a more general framework for the normalizer chain, defining a chain of idealizers in a Lie ring over Z_m whose elements are represented by integer partitions. We show how the corresponding idealizers are generated by subsets of partitions into at most m − 1 parts and we conjecture that the idealizer chain grows as the normalizer chain in the symmetric group. As evidence of this, we establish a correspondence between the two constructions in the case m = 2

Technological Innovation and Urban Processes
Full text linkTechnological innovation pushes transformatioin, rennovation and urban regenaration of areas and services. Special attention is given to the major urban centres, for the most related to nationale and/or Ue policy (Ce, 2003; Ce, 2004). A number of important questions are emerging between the reinforcement of the bigger areas, both metropolitan and urban, and the smaller centres. Moreover, according with different institutional actors it would be better more balanced process of anthropization because environmental and social reasons (APAT, 2004). In Calabria there are very few towns with more then 15.000 residents, often they are isolated and in the internal land. It requires to connect these areas by network, to push the diffusion of innovation and technology, to build up the “educated technology†(Del Nord, 1991). As said in other place (Aragona, 2003), the region is becoming to partecipate to the global village and the Ue (Ue, 1994; 1995; 1996) have policies and areas of implementation (Information Society, POR Calabbria 2000-20006; RIS+ 2001-2002). The paper faces a number of questions continuing such a topic. How are changing some of these areas that have implemented the technological innovation? Which impact are making the strategies and the choices on the spatial, functional and social context. The social effectiveness related to the quality life, said by Gasparini (1990) does it better? Could it be the outcome due to the absence of concentrated localization as is the case of other territorial areas marked by the “reticular†network (Dematteis, 1990)? Above all it requires to evaluate, said that the technological facilities are present enough, the role plays by the innovation as engine for both the cultural and awareness growth. Push for and knowledge that overcomes the mere informatization and suggestes the e-government: a formation and information path dedicated to build up new tools for local action and planning in the global competition. Identification of new settlements and spatial criteria (Appold et al., 1990), construction of urban spaces as signs of the past (Augè, 2004) but also signals of a new development and of social choesion, new citizenship (Cacciari, 1991).
