Prices of residential property in Italy: constructing a new indicator

We present a new indicator of house prices in Italy, with more extensive geographical and time coverage. The new indicator now makes it possible to analyze medium- and long-term trends with satisfactory representation of the Italian housing market. It also allows for timely updating, for prompt assessment of housing input both to the business cycle and to inflationary pressures. We offer a preliminary identification, based solely on graphical inspection, of four different property price cycles since the late 1960s; the latest began at the end of the 1990s and signaled a slowdown since 2006. Finally, we tentatively assess the effect of including transactions in dwellings in the Italian HICP basket according to the net acquisition approach, which apparently results in about a quarter point of additional inflation each year since 2000.business cycle, housing market, property prices, inflation measures

First record in Cyprus of Cinara (Cinara) cedri Mimeur (Aphididae Lachninae) on Cedrus brevifolia (Hooker fil.) Henry.

The Authors report on the discovery in South Cyprus of the aphid Cinara (Cinara) cedri Mimeur collected on the endemic cedar, Cedrus brevifolia (Hooker fil.) Henry. This is the first record of the lacnid in Cyprus. The ecological aspects of the cedar and its interaction with the related aphid species are discussed. The Authors suggest the hypothesis that the aphid may be co-endemic with its host conifer since it shows significant morphological differences compared with specimens from other European regions. The question whether the Cyprus cedar aphid can be injurious or not to its host plant is debated as well. The exact taxonomic position of this lacnid is currently under investigation

A new aphid subspecies on the endemic Cyprus cedar Cedrus brevifolia: Cinara cedri brevifoliae ssp.n. (Aphididae Lachninae)

A subspecies of Cinara cedri Mimeur, C. cedri brevifoliae ssp.n., is described from apterous viviparous females. The authors report on the discovery of this new taxon in Cyprus on the endemic cedar Cedrus brevifolia (Hooker fil.) Henry, suggesting that the aphid is co-endemic with its host conifer. Morphological evaluation is provided in order to support this conclusion and a key to separate the Cedar Cinara species is given. Moreover, new insights on the distribution of C. cedri in the Mediterranean area were gained by molecular analysis. Gene sequences were deposited in Genbank and the type specimens located in the collection (A.B.) of CREA-Research Center for Agrobiology and Pedology, Florence, Italy

Risk-adjusted econometric model to estimate postoperative costs: An additional instrument for monitoring performance after major lung resection

ObjectivesThe objectives of this study were to develop a risk-adjusted model to estimate individual postoperative costs after major lung resection and to use it for internal economic audit.MethodsVariable and fixed hospital costs were collected for 679 consecutive patients who underwent major lung resection from January 2000 through October 2006 at our unit. Several preoperative variables were used to develop a risk-adjusted econometric model from all patients operated on during the period 2000 through 2003 by a stepwise multiple regression analysis (validated by bootstrap). The model was then used to estimate the postoperative costs in the patients operated on during the 3 subsequent periods (years 2004, 2005, and 2006). Observed and predicted costs were then compared within each period by the Wilcoxon signed rank test.ResultsMultiple regression and bootstrap analysis yielded the following model predicting postoperative cost: 11,078 + 1340.3X (age > 70 years) + 1927.8X cardiac comorbidity − 95X ppoFEV1%. No differences between predicted and observed costs were noted in the first 2 periods analyzed (year 2004, $6188.40 vs$6241.40, P = .3; year 2005, $6308.60 vs$6483.60, P = .4), whereas in the most recent period (2006) observed costs were significantly lower than the predicted ones ($3457.30 vs$6162.70, P < .0001).ConclusionsGreater precision in predicting outcome and costs after therapy may assist clinicians in the optimization of clinical pathways and allocation of resources. Our economic model may be used as a methodologic template for economic audit in our specialty and complement more traditional outcome measures in the assessment of performance

MULTI-Fake-DetectiVE at EVALITA 2023: Overview of the MULTImodal Fake News Detection and VErification Task

This paper introduces the MULTI-Fake-DetectiVE shared task for the EVALITA 2023 campaign. The task was aimed at exploring multimodality within the realm of fake news and intended to address the problem from two perspectives, represented by the two sub-tasks. In sub-task 1, we aimed to evaluate the effectiveness of multimodal fake news detection systems. In sub-task 2, we sought to gain insights into the interplay between text and images, specifically how they mutually influence the interpretation of content in the context of distinguishing between fake and real news. Both perspectives were framed as classification problems. The paper presents an overview of the task. In particular, we detail the key aspects of the task, including the creation of a new dataset for fake news detection in Italian, the evaluation methodology and criteria, the participant systems, and their results. In light of the obtained results, we argue that the problem is still open and propose some future directions

SEARCHING FOR NATIVE EGG-PARASITOIDS OF THE INVASIVE ALIEN SPECIES HALYOMORPHA HALYS STÅL (HETEROPTERA PENTATOMIDAE) IN SOUTHERN EUROPE

Halyomorpha halys is an invasive species, originating from East Asia, which was accidentally introduced in some areas of North America and Europe, where severe damages to different vegetable crops and fruit plants were recorded. Several studies in different countries focused on the possibility to apply biological control by means of egg- parasitoids. The main egg-parasitoids in the original area are unfortunately non-specific and thus the application of classical biological control is questionable. On the other hand, the possibility of using augmentative biological control by native egg-parasitoids able to exploit the new host is an interesting possibility in both Europe and the USA. In a preliminary assay, frozen egg masses of H. halys were exposed in the field in Central Italy. Results showed that some eggs were exploited by parasitoids belonging to the species Anastatus bifasciatus and Ooencyrtus telenomicida. Therefore, different native egg-parasitoids species widespread in Europe were tested in the laboratory in order to explore their ability to parasitize H. halys eggs. To this end, no-choice tests were carried out in climatic chambers (26°C, 70%RH, 16:8 L:D) in order to evaluate the parasitization potential of females collected in the wild. Conducted tests pointed out that A. bifasciatus and especially O. telenomicida may be potential candidates for the biological control of H. halys. In particular, O. telenomicida was able to parasitize the 35.56% of the exposed host eggs in the lab tests. New adults successfully emerged from the 22.92% of the eggs, and on the whole, this egg-parasitoid caused a significant hatching reduction of the H. halys eggs (more than 70%). Conversely, Telenomus chloropus and Ooencyrtus pityocampae were less promising species as biocontrol agents of this agricultural pest. Preliminary trials in pear orchards consisting of field releases of laboratory-reared specimens of O. telenomicida, one of the potential candidates for biological control, showed that this parasitoid is actually able to discover egg masses of H. halys (sentinel frozen egg masses) and to successfully parasitize them

An effective method for Graphosoma lineatum (L.) long-term rearing.

A simple and time-saving technique for an effective and continuous rearing of Graphosoma lineatum (L.) (Heteroptera Pentatomidae), an alternative host for Trissolcus spp. and Ooencyrtus spp. production, was set for entomological research and maintained for a long period. Insects were maintained in containers as rearing units; 100x35x35cm cages hosted adults; 40x30x30cm cages hosted nymphs. Graphosoma lineatum was fed on seeds of Foeniculum vulgare Mill., Anethum graveolens L. and Pimpinella anisum L. Moreover, potted young plants of F. vulgare were also used as additional food source. Water for insects and plants was provided by small automatic irrigation systems. When each colony cage reached the density of 100 adult couples, the number of oviposited batches was followed up for 12 weeks. Batches laid per cage were approximately one hundred per week. Therefore the overall weekly production of six adult cages was about 8400 eggs. This technique was plain and cost effective, allowing a constant egg production throughout the year.

Peak Oxygen Consumption Measured during the Stair-Climbing Test in Lung Resection Candidates

Background: The stair-climbing test is commonly used in the preoperative evaluation of lung resection candidates, but it is difficult to standardize and provides little physiologic information on the performance. Objective: To verify the association between the altitude and the VO2peak measured during the stair-climbing test. Methods: 109 consecutive candidates for lung resection performed a symptom-limited stair-climbing test with direct breath-by-breath measurement of VO2peak by a portable gas analyzer. Stepwise logistic regression and bootstrap analyses were used to verify the association of several perioperative variables with a VO2peak O2peak from stair-climbing parameters and other patient-related variables. Results: 56% of patients climbing O2peak 22 m had a VO2peak >15 ml/kg/min. The altitude reached at stair-climbing test resulted in the only significant predictor of a VO2peak O2peak factoring altitude (p Conclusions: There was an association between altitude and VO2peak measured during the stair-climbing test. Most of the patients climbing more than 22 m are able to generate high values of VO2peak and can proceed to surgery without any additional tests. All others need to be referred for a formal cardiopulmonary exercise test. In addition, we were able to generate an equation to estimate VO2peak, which could assist in streamlining the preoperative workup and could be used across different settings to standardize this test

Patient Satisfaction after Pulmonary Resection for Lung Cancer: A Multicenter Comparative Analysis

Background: Patient satisfaction reflects the perception of the customer about the level of quality of care received during the episode of hospitalization. Objective: To compare the levels of satisfaction of patients submitted to lung resection in two different thoracic surgical units. Methods: Prospective analysis of 280 consecutive patients submitted to pulmonary resection for neoplastic disease in two centers (center A: 139 patients; center B: 141 patients; 2009–2010). Patients' satisfaction was assessed at discharge through the EORTC-InPatSat32 module, a 32-item, multi-scale self-administered anonymous questionnaire. Each scale (ranging from 0 to 100 in score) was compared between the two units. Multivariable regression and bootstrap were used to verify factors associated with the patients' general satisfaction (dependent variable). Results: Patients from unit B reported a higher general satisfaction (91.5 vs. 88.3, p = 0.04), mainly due to a significantly higher satisfaction in the doctor-related scales (doctors' technical skill: p = 0.001; doctors' interpersonal skill: p = 0.008; doctors' availability: p = 0.005, and doctors information provision: p = 0.0006). Multivariable regression analysis and bootstrap confirmed that level of care in unit B (p = 0.006, bootstrap frequency 60%) along with lower level of education of the patient population (p = 0.02, bootstrap frequency 62%) were independent factors associated with a higher general patient satisfaction. Conclusion: We were able to show a different level of patient satisfaction in patients operated on in two different thoracic surgery units. A reduced level of patient satisfaction may trigger changes in the management policy of individual units in order to meet patients' expectations and improve organizational efficiency
