Cilj istraživanja bio je ispitati mišljenje mladih potrošača (studenata) o učestalosti kupovine i konzumacije pilećeg mesa, te utjecaju zamrzavanja mesa na njegovu kakvoća. Prikupljanje podataka je provedeno metodom ankete gdje je kao instrument korišten anketni upitnik. Anketni upitnik sastojao se od 15 pitanja. Dio pitanja se odnosio na demografske pokazatelje, a dio na učestalost kupovine i konzumacije pilećeg mesa, te utjecaj zamrzavanja na njegovu kakvoću. Istraživanje je provedeno na uzorku od 156 studenata preddiplomskih i diplomskih studija s tri sastavnice Sveučilišta Josipa Jurja Strossmayera u Osijeku. U anketi su sudjelovali ispitanici u dobi od 18 do 25 godina, a prosječna dob ispitanika bila je 21 godina. Od ukupnog broja ispitanika, 79 ih je bilo sa sela, dok je 77 bilo iz grada. Rezultati istraživanja pokazali su da mladi potrošači najčešće kupuju meso u supermarketima, i to prsa i batake sa zabatacima. Također, mladi ispitanici smatraju da zamrznuto meso nije sigurnije za upotrebu u odnosu na svježe te da zamrzavanje ima negativan utjecaj na kakvoću mesa. Nadalje, smatraju da zamrzavanje najviše utječe na promjenu mirisa i okusa mesa. Rezultati provedene ankete mogu poslužiti kao okvir za buduća istraživanja drugih grupa ispitanika (različite dobne skupine) o mišljenju da li zamrzavanje mesa ima utjecaj na njegovu kakvoću., The aim of the research was to analyse the opinion of young consumers (students) on the frequency of purchase and consumption of chicken meat, and the impact of freezing on quality of its meat. Data collection was conducted using a survey method where a survey questionnaire was used as an instrument. The survey questionnaire consisted of 15 questions, where part of the survey questions was related to demographic characteristics, and part to the frequency of purchase and consumption of chicken meat, together with the impact of freezing on its quality. The questionnaire was conducted on 156 undergraduate and graduate students from three different institutions, parts of Josip Juraj Strossmayer University of Osijek. Age of participants was from 18 to 25 with average of 21 years. Out of 156 participants, 79 were from the rural area and 77 from the urban area. The results showed that young consumers usually buy chicken meat in supermarkets, mostly breasts and drumsticks with thighs. They also think that frozen meat is not safer than fresh and that freezing has a negative impact on meat quality. Furthermore, they think that greatest impact of freezing on chicken meat is deterioration of the smell and taste of meat. The results obtained in this survey can serve as a basis for future research on other consumer groups (different age groups) about their opinion on impact of freezing on chicken meat quality.questionnaire, consumers, quality, chicken meat, freezing, Ziel der Untersuchung war es, die Meinung junger Verbraucher (Studenten) über die Häufigkeit des Kaufs und des Verzehrs von Hühnerfleisch sowie über die Auswirkungen des Einfrierens auf die Qualität des Fleisches zu analysieren. Die Datenerhebung wurde mit Hilfe einer Umfrage durchgeführt, bei der ein Fragebogen als Instrument eingesetzt wurde. Der Fragebogen bestand aus 15 Fragen, wobei sich ein Teil der Fragen auf demografische Merkmale bezog und der andere Teil auf die Häufigkeit des Kaufs und des Verzehrs von Hühnerfleisch sowie die Auswirkungen des Einfrierens auf die Fleischqualität. Der Fragebogen wurde unter 156 Studenten und Doktoranden aus drei verschiedenen Einrichtungen der Universität Josip Juraj Strossmayer in Osijek ausgefüllt. Das Alter der Teilnehmer lag zwischen 18 und 25 Jahren mit einem Durchschnittsalter von 21 Jahren. Von den 156 Teilnehmern stammten 79 aus dem ländlichen und 77 aus dem städtischen Raum. Die Ergebnisse zeigten, dass junge Verbraucher in der Regel Hähnchenfleisch in Supermärkten kaufen, vor allem Brüste und Keulen mit Schenkeln. Sie sind auch der Meinung, dass gefrorenes Fleisch nicht sicherer ist als frisches und dass sich das Einfrieren negativ auf die Fleischqualität auswirkt. Darüber hinaus sind sie der Meinung, dass die größte Auswirkung des Einfrierens auf Hühnerfleisch die Verschlechterung des Geruchs und des Geschmacks des Fleisches ist. Die Ergebnisse dieser Umfrage können als Grundlage für künftige Untersuchungen bei anderen Verbrauchergruppen (verschiedenen Altersgruppen) über deren Meinung zu den Auswirkungen des Einfrierens auf die Qualität von Hühnerfleisch dienen., El objetivo de este estudio fue examinar la opinión de los consumidores jóvenes (los estudiantes) sobre la frecuencia de la compra y el consumo de la carne de pollo, y el impacto de la congelación de la carne en su calidad. La recolección de los datos fue realizada mediante un método de encuesta en el que fue utilizado la encuesta de cuestionario como instrumento. La encuesta de cuestionario constaba de 15 preguntas. Una parte de las preguntas estaba relacionada con los indicadores demográficos y otra parte con la frecuencia de la compra y del consumo de la carne de pollo y el impacto de la congelación en su calidad. La investigación se llevó a cabo con una muestra de 156 estudiantes de licenciatura y de máster de tres constituyentes de la Universidad de Josip Juraj Strossmayer en Osijek. Los encuestados que participaron en la encuesta tenían entre 18 y 25 años y la edad media de los encuestados fue 21 años. Del número total de los encuestados, 79 eran de la aldea, mientras que 77 eran de la ciudad. Los resultados de la investigación mostraron que los consumidores jóvenes compran la carne en los supermercados con mayor frecuencia, en concreto, la pechuga de pollo y la pierna de pollo con contramuslos. Además, los encuestados jóvenes creen que la carne congelada no es más segura para usar que la fresca y que la congelación tiene un impacto negativo en la calidad de carne. Además, creen que la congelación tiene el mayor efecto en cambiar el olor y el sabor de la carne. Los resultados de la encuesta pueden servir como un marco para futuras investigaciones de otros grupos de los encuestados (diferentes grupos de edad) sobre su opinión si la congelación de la carne tiene un impacto en su calidad., La ricerca aveva lo scopo di sondare l’opinione dei giovani consumatori (studenti) sulla frequenza d’acquisto e di consumazione della carne di pollo e sull’impatto della surgelazione della carne sulla sua qualità. La raccolta dei dati è avvenuta col metodo del sondaggio d’opinione, utilizzando un apposito questionario. Il questionario era composto da 15 quesiti. Parte dei quesiti riguardava gli indicatori demografici, un’altra parte la frequenza d’acquisto e di consumazione della carne di pollo e l’impatto della surgelazione sulla sua qualità. La ricerca è stata svolta su un campione di 156 studenti universitari di 1° e 2° livello iscritti a tre differenti facoltà dell’Università degli studi “Juraj Strossmayer” della città di Osijek. Al sondaggio hanno partecipato consumatori d’età compresa tra i 18 ed i 25 anni, mentre la loro età media era di 21 anni. Tra essi, 79 provenivano da un contesto abitativo rurale, mentre i restanti 77 provenivano da un contesto urbano. I risultati della ricerca hanno dimostrato che i giovani consumatori acquistano la carne di pollo, prevalentemente petto e fusi con sovracosce, con maggior frequenza nei supermercati. I giovani consumatori intervistati sono dell’opinione che la carne surgelata non sia più sicura rispetto a quella fresca e che il processo di surgelazione abbia un impatto negativo sulla qualità della carne. Inoltre, ritengono che la surgelazione alteri soprattutto l’odore ed il sapore della carne. I risultati del sondaggio svolto posso servire come quadro di riferimento per future ricerche di altri gruppi di consumatori (di differenti fasce d’età) riguardo all’opinione se il processo di surgelazione della carne incida o meno sulla sua qualità.

Discussione, a partire da un saggio di A. Wikman, sull'affidabilità dei risultati dei questionari, soprattutto in tema di customer satisfaction. Il testo sottopone a critica una serie di luoghi comuni e la fiducia acritica nei riguardi dei risultati dei sondaggi di opinione, proponendo, sempre sulla scorta di Wikman, una serie di riflessioni per migliorare l'affidabilità dei questionari stessi e per evitare un atteggiamento fideistico nei loro riguardi.

The bovine spongiform encephalopathy (BSE) saga has made painfully evident the limitations of risk communication as a one-way avenue, where information to the public about the risks they face comes after critical policy decisions have already been made. In fact, communication has even been identified as one of the key elements of what went wrong and generated the loss of trust in government discourse and in beef in Europe. This book deals with risk communication as an evolving and interactive process between decision-makers and their publics and underlines the critical importance of creating mechanisms for interaction between policy-makers and stakeholders at all stages of policy-making, in order for risk communication to be effective. The book – the result of a research project carried out in four countries (Italy, Finland, Germany, Great Britain) by an international team of researchers in 2000-2002, supported by the European Commission DG Research and led by the World Health Organization – reports on research into the strategies used by different actors to communicate about BSE and Creutzfeldt-Jakob disease (CJD) in four European countries between 1985 and 2000. These actors include the mass media, health information systems, and political actors. The research also assessed the way people construct their perceptions about risk, who they listen to and how they make decisions on risk avoidance. A range of qualitative and quantitative methods used to describe what was said as well as was the perspectives and framework assumptions espoused by those different actors. The research reported in this specific chapter begins by exploring the availability of survey data regarding perceptions of risk and trust in information sources relevant to BSE/CJD in the four countries. It reports on what part of the existing information is available, and on the findings of the few accessible results. It goes on to present results of secondary analysis, in which data from 11 Eurobarometer surveys in each of the four countries were acquired and re-analysed, along with an EU survey that included data on meat-purchasing behaviour by consumers. The chapter provides a useful discussion of issues such as public knowledge and awareness of food safety issues, public trust in various sources of information (including food producers and distributors, scientists, health officials, etc.) and of food consumption, especially of meat. The chapter also discusses in detail the strengths and weaknesses of survey methods as tools in public policy-making on food and related issues. Finally, it illuminates the important issue of what use is made by policy-makers of existing and easily accessible information on risk perceptions and trust in information sources.

A methodological approach for the assessment of hydrogeological instability events (HIEs) in the Napoli municipality area is proposed. The statistical analysis of collected data (about 900 drill holes, 600 Cone Penetration Test (CPT), climatic data and about 4500 HIEs) has shown: a) an increase in hollow and sinking (HS), deep hollow and deep sinking (DHS) as well as instability events concerning supporting wall (IEW) limited over short time, in case of intense but short rainfall; b) an increase of HS and DHS extended in time, in case of intense and protracted rainfall. The wide spatial distribution of the Anthropic Reworked Material, in the first 5 meters depth, reduced the effects of the other deposits and of their mechanical features (the mean CPT profiles show a quite variable resistance value qc) on the occurrence of the HIEs. The HS and DHS (about 62% of total instability events) occur in areas characterized by the presence of drain-sewer net and pluvial net that carry the water volume produced during intense and protracted rainfall, while the IEW (representing about 10% of total instability events) occurs mainly in areas characterized by unwelded pyroclastic deposits and medium-high slopes.

Il testo esamina i sondaggi secondo una duplice prospettiva: come tecnica di raccolta delle informazioni e come fenomeno politico-sociale. La prima parte dell'articolo individua i tratti salienti - di carattere metodologico - che contraddistinguiono il sondaggio da altre tecniche e commenta criticamente le fonti di distorsione che inficiano le informazioni prodotte per mezzo di sondaggi. La seconda parte esamina l'evoluzione storica della tecnica e la sua rilevanza per l'attività politica, per il mercato e nei mass media. Nelle conclusioni si ricorda nonostante difetti e debolezze dei sondaggi, essi hanno anche pregi che ne hanno decretato il successo anche in ambito scientifico.

Summary The general attitude of local population toward immigration is one of the main variable in the process of immigrants' integration. It has a significant effect on political debate and policies themselves. The Institute for Population Research (IRP) of the National Research Council (CNR) has included this subject in three of its surveys on the attitudes and opinions of the Italians towards population trends. The first of these surveys was conducted between December 1987 and January 1988, the second in March 1991, and the third in January 1997. They offer the possibility to follow the evolution of this important aspect of migration. The aim of the paper is to describe the changes in attitudes and opinions of Italians towards immigration and immigrants in a decisive decade for the role of the new-comers in the Italian society. Particular attention is devoted to the results of the most recent survey. The statistical analysis of the data is also based on a cluster analysis, in order to highlight the characteristics of people with similar opinions.
