Edible insects and global food security

Starting in 2008 and lasting up until 2011, the crisis in agricultural and, in particular, cereal prices triggered a period of riots that spread from the Mediterranean basin to the rest of the world, reaching from Asia to Central America and the African continent. [...]

Income levels and farm economic viability in Italian farms: An analysis of FADN data

In the European Union legislative proposals for the next Common Agricultural Policy (CAP) the income support remains an essential part of the CAP. This paper analyses agricultural income levels, the role of EU aids in ensuring fair levels of income and how different socio-economic and structural characteristics affect farms' economic viability. Italian Farm Accountancy Data Network (FADN) data have been processed and economic viability has been assessed by comparing Farm Net Income to a reference income and by estimating a profitability index to check whether the agricultural activities remunerate factors owned by the farmer and his/her family. After an explorative analysis, two multinomial logit models have been estimated to evaluate how structural and socio-economic characteristics affect the likelihood of a farm to be viable with and without EU aids. Both structural farm characteristics and farmer's production strategies explain the likelihood of a farm to be viable in the short and in the medium-long term. Farms are more likely to be viable as the size increases and the higher the capital intensity, while viability likelihood decreases with the farmer's age, when the holder is a woman, and the farm is localized in Southern Italy. CAP payments do not modify the factors that affect farm viability but can change their weight

Social Emotions and Good Provider Norms in Tackling Household Food Waste: An Extension of the Theory of Planned Behavior

Many studies have explored the antecedents of food waste in the framework of the theory of planned behavior (TPB). Scholars have also made efforts to add explaining variables to the original TPB, with mixed results; they often fail to demonstrate the incremental validity of the extended models. In the current study, we sought to assess whether an extended TPB model including social emotions and Good Provider norms could predict intention to reduce food waste. We also measured two behaviors which may be predicted by intentions to reduce food waste: (1) reducing servings and (2) using leftovers. The results show that social emotions help explain leftovers utilization, whereas the Good Provider norms are inversely correlated to the reduction of servings. Compared to the traditional TPB model, the extended version has more predictive power, especially as regards reducing servings

Domestic food waste and covid-19 concern: An application of the theory of planned behaviour

The ongoing Covid-19 pandemic rapidly and dramatically disrupted household behaviours in almost all areas and, among these, eating behaviours and daily food patterns have also been radically altered. All reported changes have potential effects in terms of food waste, which is a global problem that mainly occurs at household level. Many scholars attempted to understand the antecedents of food waste in the framework of Theory of Planned Behaviour (TPB). In this paper we follow this strain of research by focussing on two different behaviours, suggested by the Waste Framework Directive of the EU, namely (a) reducing servings and (b) using leftovers, which may be predicted by the intention to reduce food waste. An online questionnaire containing the key constructs of the TPB and the concern towards the pandemic was administered to a sample of 201 Italian consumers. Results show that the TPB model was confirmed for both behaviours while the Covid-19 concern had no direct effect. However, in the case of portion reduction, there is a significant interaction between concern and intention not to waste food. That is, the effect of intention on reducing servings is increasing as the level of concern increases. Therefore, some indications on how to address food waste policies are drawn

Critical Care Nurse Burnout in America

Prediction tools that assess nursing burnout within newly graduated nurses in critical care since the outbreak of COVID-19 allow for better understanding of the decreased rates for nursing job satisfaction, fatigue among nurses, and high stress rates that create undesirable conditions. This posed the question: within RNs that work in critical care, will yearly training to create a safe work environment and mental health resources provided by nursing management reduce burnout levels within 5 years of employment, compared to RNs with fewer resources, in the United States? A literature search for this research was narrowed on PubMed and CINAHL. The following terms were used: nursing burnout, critical care, intervention, and 12 sources were chosen out of over 1,000 results. Inclusion criteria included peer-reviewed journal articles and systematic reviews from 2019 to present, with a focus on burnout in critical care nurses.. Limitations include newly graduated nurses, studies in the last 5 years, and must include data from the United States. The literature indicated the integration of stress reduction techniques created positive changes in health behavior and the decrease of nursing burnout in new graduates. Examples of stress reduction techniques include reducing patient load for nurses, proper resources on the unit, and physical and mental health encouragement from nurse management and leaders. The literature supports healthcare organizations implementing stress reduction strategies for new nurses, thus ensuring adequate knowledge for a full critical care assignment

Perceived risk of insect-based foods: An assessment of the entomophagy attitude questionnaire predictive validity

Insects are a promising alternative protein source and their possible integration in the human diet has been extensively studied, also with reference to the degree of consumer acceptability and the main factors determining reluctance among Western consumers. Several studies have also proposed the use of protein meals derived from insects in animal feed as a possible way to promote the development of the insect chain. Consumer attitudes, perceived risks, and intention to eat insect-based foods have been extensively researched, yet the relationships between those factors are still unclear. On a sample of 202 Italian consumers, the present research used the Entomophagy Attitude Questionnaire (EAQ) to analyse the degree of acceptability of insects as food and meat obtained from animals raised on insect-based feeds with a specific focus on the role of attitudes and perceived risk. The research also evaluated the differences in acceptability between different types of animals fed with insects. The results show that the intention to engage in entomophagy is significantly correlated with all three of the EAQ’s subscales, as well as with perceived risk. However, the effect of perceived risk does not significantly improve the predictive validity of EAQ with respect to the intention to eat insect-based food. The results also show that the degree of acceptability for different insect meal-reared animals changes among consumers: beef and pork are characterized by a lower degree of acceptability, while poultry and fish are more accepted by consumers

The effect of verbal and iconic messages in the promotion of high-quality mountain cheese : A non-hypothetical BDM approach

To ensure the sustainable development of mountain livestock farming, the adequate remuneration of high-quality dairy products is fundamental. In this sense, communication strategies aimed at promoting mountain products and ensure better positioning and higher market prices are fundamental. The present research seeks to expand the literature regarding consumers’ willingness to pay for mountain foods by using an online real auction experiment aimed at evaluating the premium price that consumers are willing to pay for summer over winter mountain cheese, depending on the information provided concerning the taste anticipation or animal welfare. The results showed an overall small premium price given to the higher quality summer cheese; this could be, partially, due to a generally low degree of consumer knowledge about mountain dairy farming. With reference to communication strategies, the results provide evidence about the effectiveness of the rational messages founded upon sensorial characteristics and the anticipated taste of cheese. In addition, this study explored that adding a logo had no main effect on the price premium participants were willing to pay. This may be due to the fact that logos and claims, having a lower information content, are more indicated to lead the choice of consumers with a higher level of awareness. In the conclusion section, policy and agribusiness implications of the findings are provided

Exploring consumers’ perception and willingness to pay for “Non-Added Sulphite” wines through experimental auctions: A case study in Italy and Spain

Although scientific literature is still uncertain towards the real causes that can link headache episodes with moderate wine consumption, a growing proportion of consumers seems to address sulphites as possible culprits. Hence, the objective of this study is to assess consumers` willingness to pay for wine bearing a sulphites-free label in two traditional wine producing countries, Italy and Spain. The methodological framework is based on the specification of the Becker-DeGroot-Marschak (BDM) type of auction applied to consumers purchasing wine in the supermarket stores of both countries. A left censored Tobit model is used to analyse the bidding behaviour for conventional and “Non-Added Sulphite” (NAS) wine. Results in both countries show that consumers who link the headaches with the consumption of sulphite are willing to exchange the habitually consumed bottle of wine with a NAS wine and pay extra premium prices.Esta investigación se ha llevado a cabo gracias al apoyo financiero de la Organización Internacional de la Viña y el Vino (OIV).Publishe

Morphological and Molecular Evolution Are Not Linked in Lamellodiscus (Plathyhelminthes, Monogenea)

Lamellodiscus Johnston & Tiegs 1922 (Monogenea, Diplectanidae) is a genus of common parasites on the gills of sparid fishes. Here we show that this genus is probably undergoing a fast molecular diversification, as reflected by the important genetic variability observed within three molecular markers (partial nuclear 18S rDNA, Internal Transcribed Spacer 1, and mitonchondrial Cytochrome Oxidase I). Using an updated phylogeny of this genus, we show that molecular and morphological evolution are weakly correlated, and that most of the morphologically defined taxonomical units are not consistent with the molecular data. We suggest that Lamellodiscus morphology is probably constrained by strong environmental (host-induced) pressure, and discuss why this result can apply to other taxa. Genetic variability within nuclear 18S and mitochondrial COI genes are compared for several monogenean genera, as this measure may reflect the level of diversification within a genus. Overall our results suggest that cryptic speciation events may occur within Lamellodiscus, and discuss the links between morphological and molecular evolution

Evolutionary relationships and divergence times among the native rats of Australia

Background The genus Rattus is highly speciose and has a complex taxonomy that is not fully resolved. As shown previously there are two major groups within the genus, an Asian and an Australo-Papuan group. This study focuses on the Australo-Papuan group and particularly on the Australian rats. There are uncertainties regarding the number of species within the group and the relationships among them. We analysed 16 mitochondrial genomes, including seven novel genomes from six species, to help elucidate the evolutionary history of the Australian rats. We also demonstrate, from a larger dataset, the usefulness of short regions of the mitochondrial genome in identifying these rats at the species level. Results Analyses of 16 mitochondrial genomes representing species sampled from Australo-Papuan and Asian clades of Rattus indicate divergence of these two groups ~2.7 million years ago (Mya). Subsequent diversification of at least 4 lineages within the Australo-Papuan clade was rapid and occurred over the period from ~ 0.9-1.7 Mya, a finding that explains the difficulty in resolving some relationships within this clade. Phylogenetic analyses of our 126 taxon, but shorter sequence (1952 nucleotides long), Rattus database generally give well supported species clades. Conclusions Our whole mitochondrial genome analyses are concordant with a taxonomic division that places the native Australian rats into the Rattus fuscipes species group. We suggest the following order of divergence of the Australian species. R. fuscipes is the oldest lineage among the Australian rats and is not part of a New Guinean radiation. R. lutreolus is also within this Australian clade and shallower than R. tunneyi while the R. sordidus group is the shallowest lineage in the clade. The divergences within the R. sordidus and R. leucopus lineages occurring about half a million years ago support the hypotheses of more recent interchanges of rats between Australia and New Guinea. While problematic for inference of deeper divergences, we report that the analysis of shorter mitochondrial sequences is very useful for species identification in rats
