The effect of adding features on product attractiveness: the role of product perceived congruity

Technological progress has been enabling companies to add disparate features to their existing products. This research investigates the effect of adding more features on consumers’ evaluation of the product, by examining in particular the role of the congruity of the features added with the base product as a variable the moderates the effect of increasing the number of features. Grounding on schema-congruity theory, I propose that the cognitive elaboration associated with the product congruity of the features added explains consumers’ evaluation as the number of new features increases. In particular, it is shown that consumers perceive a benefit from increasing the number of features only when these features are congruent with the product. The underlying mechanisms that explains this finding predicts that when the number of incongruent features increases the cognitive resources necessary to elaborate such incongruities increase and consumers are not willing to spend such resources. However, I further show that when encouraged to consider the new features thoughtfully, consumers do seem able to infer value from increasing the number of moderately incongruent features. Nonetheless, this finding does not apply for those new features that are extremely incongruent with the product. Further evidence for consumers’ ability to resolve the moderate incongruity associated with adding more features is also shown, by studying the moderating role of temporal construal. I propose that consumers perceive an increase in product evaluation as the number of moderately incongruent features increases when consumers consider purchasing the product in the distant future, whereas such an increase is not predicted for the near future scenario. I verify these effect in three experimental studies. Theoretical and managerial implications, and possible avenues of future research are also suggested.

Visual scanning in sports actions: comparison between soccer goalkeepers and judo fighters

Visual search and oculomotor behaviour are believed to be very relevant for athlete performance, especially for sports requiring refined visuo-motor coordination skills. Modern coaches believe that a correct visuo-motor strategy may be part of advanced training programs. In this thesis two experiments are reported in which gaze behaviour of expert and novice athletes were investigated while they were doing a real sport specific task. The experiments concern two different sports: judo and soccer. In each experiment, number of fixations, fixation locations and mean fixation duration (ms) were considered. An observational analysis was done at the end of the paper to see perceptual differences between near and far space. Purpose: The aim of the judo study was to delineate differences in gaze behaviour characteristics between a population of athletes and one of non athletes. Aspects specifically investigated were: search rate, search order and viewing time across different conditions in a real-world task. The second study was aimed at identifying gaze behaviour in varsity soccer goalkeepers while facing a penalty kick executed with instep and inside foot. Then an attempt has been done to compare the gaze strategies of expert judoka and soccer goalkeepers in order to delineate possible differences related to the different conditions of reacting to events occurring in near (peripersonal) or far (extrapersonal) space. Judo Methods: A sample of 9 judoka (black belt) and 11 near judoka (white belt) were studied. Eye movements were recorded at 500Hz using a video based eye tracker (EyeLink II). Each subject participated in 40 sessions for about 40 minutes. Gaze behaviour was considered as average number of locations fixated per trial, the average number of fixations per trial, and mean fixation duration. Soccer Methods: Seven (n = 7) intermediate level male volunteered for the experiment. The kickers and goalkeepers, had at least varsity level soccer experience. The vision-in-action (VIA) system (Vickers 1996; Vickers 2007) was used to collect the coupled gaze and motor behaviours of the goalkeepers. This system integrated input from a mobile eye tracking system (Applied Sciences Laboratories) with an external video of the goalkeeper’s saving actions. The goalkeepers took 30 penalty kicks on a synthetic pitch in accordance with FIFA (2008) laws. Judo Results: Results indicate that experts group differed significantly from near expert for fixations duration, and number of fixations per trial. The expert judokas used a less exhaustive search strategy involving fewer fixations of longer duration than their novice counterparts and focused on central regions of the body. The results showed that in defence and attack situation expert group did a greater number of transitions with respect to their novice counterpart. Soccer Results: We found significant main effect for the number of locations fixated across outcome (goal/save) but not for foot contact (instep/inside). Participants spent more time fixating the areas in instep than inside kick and in goal than in save situation. Mean and standard error in search strategy as a result of foot contact and outcome indicate that the most gaze behaviour start and finish on ball interest areas. Conclusions: Expert goalkeepers tend to spend more time in inside-save than instep-save penalty, differences that was opposite in scored penalty kick. Judo results show that differences in visual behaviour related to the level of expertise appear mainly when the test presentation is continuous, last for a relatively long period of time and present a high level of uncertainty with regard to the chronology and the nature of events. Expert judoist performers “anchor” the fovea on central regions of the scene (lapel and face) while using peripheral vision to monitor opponents’ limb movements. The differences between judo and soccer gaze strategies are discussed on the light of physiological and neuropsychological differences between near and far space perception.

Media activism on and off line by Italian adolescents and young adults

From several researchers it appears that Italian adolescents and young people are grown up with commercial television which is accused to contain too much violence, sex, reality shows, advertising, cartoons which are watched from 1 to 4 hours daily. Adolescents are also great users of mobile phones and spend a lot of time to use it. Their academic results are below the average of Ocse States. However the widespread use of communication technology and social networks display also another side of adolescents who engage in media activism and political movement such as Ammazzateci tutti!, Indymedia, Movimento 5 Stelle, Movimento No Tav. In which way does the world economic crisis -with the specific problems of Italy as the cutting founds for school, academic research and welfare, the corruption of political class, mafia and camorra organisation induce a reaction in our adolescents and young people? Several researches inform us about their use of internet in terms of spending time but, more important, how internet, and the web 2.0, could be an instrument for their reaction? What do they do online? How they do it? Which is the meaning of their presence online? And, has their online activity a continuity offline? The research aims are: 1. Trough a participant observation of Social Network profiles opened by 10 young active citizens, I would seek to understand which kind of social or political activities they engage in online as individuals and which is the meaning of their presence online. 2. To observe and understand if adolescents and young people have a continuity of their socio-political engagement online in offline activities and which kind of experiences it is. 3. Try to comprehend which was (or which were) the significant, learning experiences that convinced them about the potential of the web as tool for their activism.

Tutela e valorizzazione delle produzioni agroalimentari di qualità attraverso strategie di brand management.Il modello Coop.

Questa tesi di dottorato verte sull'individuazione di politiche industriali atte ad implementare il mercato dei prodotti a denominazione di origine. Inevitabilmente, l’analisi economica dei prodotti agroalimentari tipici di qualità implica anche l’approfondimento e l’individuazione, delle problematiche connesse con la creazione di un valore addizionale per il consumatore, rispetto a quello dei prodotti standardizzati. Questo approccio richiama l’attenzione, da una parte, sulle caratteristiche della domanda e sulla disponibilità del consumatore a riconoscere e apprezzare questo plus-valore, dall’altra sulle strategie che l’offerta può attivare per conseguire un premium price rispetto al prodotto standardizzato. Le certificazioni comunitarie Dop, Igp e Stg oltre che il marchio di prodotto biologico racchiudono, solitamente, tali dinamiche valoriali ma sono tutt’oggi poco conosciute dai consumatori. Diversi studi internazionali dimostrano, infatti, che la maggioranza dei cittadini comunitari ignorano il significato delle certificazioni di qualità. L’ipotesi di fondo di questo studio si basa sulla possibilità di fidelizzare questi marchi con i brand della grande distribuzione già affermati, come quello di Coop. Analizzare gli effetti dell’introduzione di prodotti private label a denominazione di origine nel mercato della grande distribuzione organizzata italiana ci permetterebbe di comprendere se questo segmento di mercato può aiutare il settore delle Dop/Igp. Questo studio ha cercato di verificare se il prodotto private label a denominazione di origine, riesca a sfruttare il doppio binario di fiducia rappresentato dal marchio comunitario unito a quello dell’impresa di distribuzione. Per comprendere la propensione del consumatore a spendere di più per questi prodotti, abbiamo utilizzato l’analisi dell’elasticità della domanda sul prezzo dei dati scanner fornitici da Coop Adriatica. Siamo riusciti a dimostrare tale positivo connubio confermato anche da una indagine demoscopica effettuata ad hoc sui consumatori.

Evaluation of an intervention focusing on children to promote physical activity in the entire community: Feasibility, effectiveness and sustainability over time.

Regular physical activity (PA) during childhood is associated with physical, mental, emotional and social health benefits. The constant practice of PA is considered one of the best buys available in public health. The World Health Organization (WHO) recommends to perform at least 60 minutes per day of moderate to vigorous PA for children and adolescents in order to obtain health benefits. However, globally, this level of PA is hardly achieved. Children and adolescent who do not reach the recommended levels of PA are defined as physically inactive and nowadays physical inactivity constitutes a new type of pandemic. For this reason, the WHO launched a global action plan addressing physical activity with a goal of reducing physical inactivity in children and youth. The plan also included recommendation to improve individual and community health and contribute to the social, cultural and economic development of all nations. Worldwide, children and adolescents spend a significant amount of time in school and for this reason the school represents a fundamental educational setting that can play a pivotal role increasing students’ PA. Opportunities to be physically active should not be considered purely in relation to when children attend physical education classes but also making physical activity available during the school day, such as physically active lessons, and multicomponent PA interventions. Since school-based PA interventions are quite numerous, the present thesis focused on interventions delivered during school hours and that integrate small doses of PA as part of routine instruction. This type of intervention is called “Active Breaks.” Active Breaks consists of brief 5–15 minutes sessions of PA led by teachers who introduce short bursts of PA into the academic lesson. In light of this the present thesis aims to evaluate the feasibility, efficacy and sustainability of an Active Breaks intervention targeting children to promote PA.

Il benessere del suino pesante italiano: esperienze di ricerca in allevamento, durante il trasporto e nella percezione dei consumatori

Questo elaborato contiene studi riguardanti il benessere del suino pesante italiano ed in particolare si sofferma su alcuni aspetti particolarmente significativi per il miglioramento del benessere. Gli aspetti in esame hanno riguardato la percezione da parte del consumatore italiano del benessere in azienda; inoltre sono stati studiati gli effetti sul benessere di alcune caratteristiche dell'allevamento e di aspetti multifattoriali riguardanti il trasporto al macello. Alla luce dei lavori contenuti in questo lavoro, emerge come una revisione della normativa, anche considerando la categoria dei suini pesanti, possa migliorare notevolmente le loro condizioni di benessere. I consumatori italiani, infatti, hanno confermato di essere attenti e interessati al benessere animale, oltre che disposti a spendere di più per gli animali derivanti da pratiche innovative e più rispettose del benessere, come l'immunocastrazione. Un altro criterio importante, soprattutto in questa categoria di prodotti, è la disponibilità di spazio. Le nostre evidenze sperimentali dimostrano che garantire a questa categoria di suini requisiti di spazio superiori a quelli richiesti dalla normativa migliora il comportamento degli animali e i parametri di produzione. Infine, in termini di trasporto, lo studio da noi condotto ha permesso di identificare parametri da utilizzare come indicatori del livello di stress degli animali, risultando in una buona correlazione con i parametri di stress ematobiochimico. A conclusione di queste variegate esperienze di ricerca, si evidenzia quindi come investire in ulteriori impegni da parte del settore suinicolo, perseguendo l'obiettivo di ridurre al minimo gli stress a cui sono sottoposti i suini pesanti nel corso della loro vita, dall'adozione di tecniche di castrazione meno invasive, il miglioramento delle condizioni di allevamento e di trasporto, dovrebbe essere l'obiettivo comune di tutti i protagonisti della filiera, anche con l’obiettivo di ottenere un prodotto finale con un valore etico che soddisfi le aspettative implicite del consumatore.

Integrating the age factor in designing industrial environments and workstations in the workforce ageing era

As people spend a third of their lives at work and, in most cases, indoors, the work environment assumes crucial importance. The continuous and dynamic interaction between people and the working environment surrounding them produces physiological and psychological effects on operators. Recognizing the substantial impact of comfort and well-being on employee satisfaction and job performance, the literature underscores the need for industries to implement indoor environment control strategies to ensure long-term success and profitability. However, managing physical risks (i.e., ergonomic and microclimate) in industrial environments is often constrained by production and energy requirements. In the food processing industry, for example, the safety of perishable products dictates storage temperatures that do not allow for operator comfort. Conversely, warehouses dedicated to non-perishable products often lack cooling systems to limit energy expenditure, reaching high temperatures in the summer period. Moreover, exceptional events, like the COVID-19 pandemic, introduce new constraints, with recommendations impacting thermal stress and respiratory health. Furthermore, the thesis highlights how workers' variables, particularly the aging process, reduce tolerance to environmental stresses. Consequently, prolonged exposure to environmental stress conditions at work results in cardiovascular disease and musculoskeletal disorders. In response to the global trend of an aging workforce, the thesis bridges a literature gap by proposing methods and models that integrate the age factor into comfort assessment. It aims to present technical and technological solutions to mitigate microclimate risks in industrial environments, ultimately seeking innovative ways to enhance the aging workforce's comfort, performance, experience, and skills. The research outlines a logical-conceptual scheme with three main areas of focus: analyzing factors influencing the work environment, recognizing constraints to worker comfort, and designing solutions. The results significantly contribute to science by laying the foundation for new research in worker health and safety in an ageing working population's extremely current industrial context.
