Which affects affect the use of new technologies? Italian adaptation of the Internet Motive Questionnaire for Adolescents (IMQ-A) and criterion validity with problematic use and body dissatisfaction
Given the negative role of problematic use of new technological devices (NTD) in behavioral and psychological domains, the aim of the study is the Italian adaptation and validation of the Internet Motive Questionnaire for Adolescents (IMQ-A) in order to understand the motivation for the use of NTD. A total of 769 students 10-19 aged (M = 13.22, SD = 1.56) completed the IMQ-A, the Collins Figures Rating Scale, and two measures regarding the problematic NTD use, focused on overuse during the night and during meals. The IMQ-A showed adequate internal consistency with regard to its four subscales: Coping (α = .84), Social (α = .80), Enhancement (α = .80), and Conformity (α = .68) motives. However, with regard to factorial structure, a threefactor model (excluding Conformity subscale) showed slightly better fit indices than the original model. Coping motive was correlated with problematic NTD use and succeeded in predicting higher scores in body dissatisfaction as evidence of criterion-related and external validity. The Italian adaptation of the IMQ-A can be useful in both research and clinical fields, in order to propose alternative strategies for coping to users and to improve emotion regulation facets
Thermal Noise-Boosting Effects in Hot-Wire-Based Micro Sensors
This article proposes an original approach aimed at modelling the noise density in sensors based on a single hot wire or pairs of thermally coupled wires. The model consists in an original combination of a previous electrothermal model of the wire with well-established assumptions on the thermal noise in conductors that carry moderate current densities. A simple method for estimating the model parameters with simple impedance spectroscopy is suggested. The predicted power spectral densities of the wire thermal noise differ from the result of previously presented analytical models, stimulating further experimental studies. The effects of the electrothermal feedback of both hot wires and hot-wire pairs on flicker noise is also intrinsically covered by the proposed approach

An in situ assessment of local adaptation in a calcifying polychaete from a shallow CO 2 vent system
Ocean acidification (OA) is likely to exert selective pressure on natural populations. Our ability to predict which marine species will adapt to OA and what underlies this adaptive potential is of high conservation and resource management priority. Using a naturally low-pH vent site in the Mediterranean Sea (Castello Aragonese, Ischia) mirroring projected future OA conditions, we carried out a reciprocal transplant experiment to investigate the relative importance of phenotypic plasticity and local adaptation in two populations of the sessile, calcifying polychaete Simplaria sp. (Annelida, Serpulidae, Spirorbinae): one residing in low pH and the other from a nearby ambient (i.e. high) pH site. We measured a suite of fitness-related traits (i.e. survival, reproductive output, maturation, population growth) and tube growth rates in laboratory-bred F2 generation individuals from both populations reciprocally transplanted back into both ambient and low-pH in situ habitats. Both populations showed lower expression in all traits, but increased tube growth rates, when exposed to low-pH compared with high-pH conditions, regardless of their site of origin suggesting that local adaptation to low-pH conditions has not occurred. We also found comparable levels of plasticity in the two populations investigated, suggesting no influence of long-term exposure to low pH on the ability of populations to adjust their phenotype. Despite high variation in trait values among sites and the relatively extreme conditions at the low pH site (pH < 7.36), response trends were consistent across traits. Hence, our data suggest that, for Simplaria and possibly other calcifiers, neither local adaptations nor sufficient phenotypic plasticity levels appear to suffice in order to compensate for the negative impacts of OA on long-term survival. Our work also emphasizes the utility of field experiments in natural environments subjected to high level of pCO2 for elucidating the potential for adaptation to future scenarios of OA
Effects and safety of delayed versus early umbilical cord clamping in newborns of HIV-infected mothers
Objective: To investigate the effect of a 2 minutes-delayed cord clamp (DCC) versus early cord clamp (ECC) on neonate haemoglobin concentration 24 hours and 1 month after birth, and assess the safety of DCC concerning the risk of HIV infection. Design: Sixty-four mother-infant peers were enrolled. All mothers were on stable ARV therapy. Viral load, CD4+count and blood haemoglobin (Hb) concentrations 24 hours before delivery were collected from all mothers and their infants. Methods: All patients were enrolled at the Department of Paediatrics, AO FBF Sacco Hospital in Milan, and were followed until 18 months after birth. Women with haematological diseases and obstetrical complications were excluded. All of 64 mother and infants couples (32 ECC group and 32 DCC group) completed the study. ECC and DCC are defined as application of umbilical clamp within 30 seconds and 120 seconds after birth, respectively. Results: Mean birth weight was significantly higher in the DCC compared with ECC group. Mean Hb levels at birth were significantly higher in DCC than in ECC group (p\ue2\u80\u89=\ue2\u80\u89.05): this difference persisted at 1 month of life. All newborns showed negative viral load. Conclusions: DCC 2 minutes after birth is proven to be a safe procedure, particularly beneficial in newborns from HIV mothers. The risk of anemia is significantly decreased at 24 hours after birth and persists at age of 1 month without any increased risk of neonatal jaundice or polycitemia
Spectroscopy of 98Ru
The nucleus 98 Ru has been investigated by means of Îł - Îł coincidence, Îł - Îł angular correlation and K-internal conversion coefficient measurements. The results have led to spin-parity assignment to several levels and to the determination of E 2/ M 1 mixing ratios for the most intense transitions

Halyomorpha halys in Italy: first results of field monitoring in fruit orchards
The invasive pest Brown Marmorated Stink Bug (BMSB) Halyomorpha halys (Heteroptera, Pentatomidae) was detected for the first time in Italy in September 2012 in Modena province (Northern Italy) during an insect collection for educational purposes. A survey performed in 2013 allowed to detect its presence in Emilia Romagna, Lombardy and Piedmont regions. In 2014, in the provinces of Modena, Reggio Emilia and Bologna a periodical active field monitoring was performed using tree beating, sweep-net and visual observations in selected orchards and vineyards, recording numbers of BMSB adults and nymphs, and of other Heteroptera. Besides, fruit injury and crop loss were recorded at harvest. Partial results from field data obtained between April and July 2014 are presented, indicating that BMSB is already becoming an important pest of fruit orchards and that special attention should be deserved to monitor its spread all over the region and the whole Italian country
Thoracic myopericytoma in an older adult, rare but possible: A case report
Myopericytoma is a rare tumor generally arising from skin and soft tissues of extremities, trunk, head, and neck regions, rarely from visceral sites. An intrathoracic visceral localization may carry a broad differential diagnosis including primary lung, pleura and chest wall lesions, or metastatic lesions. To date, any radiological features have been recognized and diagnosis of myopericytoma with intrathoracic localization remains still challenging. Here, we describe the case of a subpleural lesion incidentally diagnosed in an older adult affected by gastric cancer. Radiological features did not allow a differential diagnosis between a benign lesion, a primary tumor, or a metastasis. After resection, the histological examination showed histopathological features congruent with the diagnosis of myopericytoma. This unusual presentation reflects the need to share clinical, radiological, and histopathological data about this uncommon but frequently misdiagnosed disease
