The use of the Internet and new technologies now seems to permeate the entire society, affecting every aspect of daily life. Although this change is characterized by undeniable positive aspects, it simultaneously bears a number of risks which are higher especially with respect to the growing number of younger users. In fact, young people, as the most involved in cyber space, are an age group most exposed to the dangers of improper and not aware use of electronic tools. The specific aim of this research was to study unwanted online attentions (UOA) among a sample of Italian students (N?=?585, mean age?=?14.5), identifying UOA as all those behaviors carried out through the Internet and technology to annoy, disturb, offend, humiliate, intimidate, threat, harass, harm or attack others. The online questionnaire investigated the online habits of the students, the presence of UOA and the characteristics of victims and perpetrators, the perception and emotional impact of such conducts, and the victims' possible reactions. The findings offer an estimate of the prevalence of these behaviors in the population of this age group in the area considered. More importantly, the results reveal a very high involvement in technology by the students accompanied by a lack of awareness regarding the risks connected to technology use as well as a low perception of UOA. These results give evidence of the needs in terms of prevention and education instruments in order to improve the system of responses to cybervictimization among young people. 相似文献

Recent national events have brought the issue of police-community relations into the public eye. Even though a large body of academic research exists on the predictors of public attitude toward police, very little is known about how public perceptions of police accountability influence satisfaction with the police. This study seeks to fill that gap by using ordered logistic regression and multi-year community-level survey data from one Western city (n = 3725) to examine the relationship between satisfaction with police accountability and overall attitudes toward the police. The results indicate that respondent satisfaction with police accountability was a strong, consistent predictor of satisfaction with local police, even after controlling for other important variables, such as race/ethnicity and community context. The findings suggest that public perceptions relating to the control of police officer conduct should be considered when assessing the predictors of attitudes toward the police. 相似文献

AIM:To profile protein expression in mucosal biopsies from patients with chronic refractory pouchitis following antibiotic or probiotic treatment,using a comparative proteomic approach. METHODS:Two-dimensional polyacrylamide gel electrophoresis and matrix-assisted laser desorption/ ionization-time of flight mass spectrometry were used to characterize the changes related to antibiotic therapy in the protein expression profiles of biopsy samples from patients with chronic refractory pouchitis.The same proteom... 相似文献

This fourth article of the series is taking an in‐depth analysis at the visible aging of latent fingermarks regarding changes in ridge widths over time. The objective is to quantify and statistically describe significant ridge size variations under controlled indoor conditions. The effect of three environmental variables are examined: type of secretion (sebaceous‐ and eccrine‐rich) and type of substrate (glass and polystyrene) when aged in three light conditions (direct natural light, shade, and dark). Prior to width measurements, fresh and aged fingermarks were powdered with titanium dioxide (TiO2) and sequentially photographed at predetermined times over 6 months. Three independent observers measured the ridges from thirty predetermined locations using strategically placed intersecting lines on the print. Results indicate that fingermarks deposited on glass are more resilient to degradation compared with those deposited on plastic. The presence of direct natural light plays a negligible role on degradation compared to secretion and substrate types. 相似文献

The assessment of facial mimicry is important in forensic anthropology; in addition, the application of modern 3D image acquisition systems may help for the analysis of facial surfaces. This study aimed at exposing a novel method for comparing 3D profiles in different facial expressions. Ten male adults, aged between 30 and 40 years, underwent acquisitions by stereophotogrammetry (VECTRA‐3D ® ) with different expressions (neutral, happy, sad, angry, surprised). The acquisition of each individual was then superimposed on the neutral one according to nine landmarks, and the root mean square (RMS) value between the two expressions was calculated. The highest difference in comparison with the neutral standard was shown by the happy expression (RMS 4.11 mm), followed by the surprised (RMS 2.74 mm), sad (RMS 1.3 mm), and angry ones (RMS 1.21 mm). This pilot study shows that the 3D–3D superimposition may provide reliable results concerning facial alteration due to mimicry. 相似文献

Hand–foot syndrome, a chemotherapy‐induced cutaneous toxicity, can cause an alteration in fingerprints causing a setback for cancer patients due to the occurrence of false rejections. A colon cancer patient was fingerprinted after not having been able to use fingerprint recognition devices after 6 months of adjuvant chemotherapy. The fingerprint images were digitally processed to improve fingerprint definition without altering the papillary design. No evidence of skin toxicity was present. Two months later, the situation returned to normal. The fingerprint evaluation conducted on 15 identification points highlighted the quantitative and qualitative fingerprint alteration details detected after the end of chemotherapy and 2 months later. Fingerprint alteration during chemotherapy has been reported, but to our knowledge, this particular case is the first ever reported without evident clinical signs. Alternative fingerprint identification methods as well as improved biometric identification systems are needed in case of unexpected situations. 相似文献
