Do cyber-birds flock together? Comparing deviance among social network members of cyber-dependent offenders and traditional offenders
The distinct setting in which cyber-dependent crime takes place may reduce the similarity in the deviance of social network members. We test this assumption by analysing the deviance of the most important social contacts of cyber-dependent offenders and traditional offenders in the Netherlands (N = 344 offenders; N = 1131 social contacts). As expected, similarity in deviance is weaker for cyber-dependent crime. Because this is a strong predictor of traditional offending, this has important implications for criminological research and practice. Additionally, for both crime types the offending behaviour of a person is more strongly linked to the deviance of social ties if those ties are of the same gender and age, and if the offender has daily contact with them. Implications and future criminological research suggestions are discussed

Modification of light utilization for skeletal growth by water flow in the scleractinian coral Galaxea fascicularis
In this study, we tested the hypothesis that the importance of water flow for skeletal growth (rate) becomes higher with increasing irradiance levels (i.e. a synergistic effect) and that such effect is mediated by a water flow modulated effect on net photosynthesis. Four series of nine nubbins of G. fascicularis were grown at either high (600 µE m-2 s-1) or intermediate (300 µE m-2 s-1) irradiance in combination with either high (15–25 cm s-1) or low (5–10 cm s-1) flow. Growth was measured as buoyant weight and surface area. Photosynthetic rates were measured at each coral’s specific experimental irradiance and flow speed. Additionally, the instantaneous effect of water flow on net photosynthetic rate was determined in short-term incubations in a respirometric flowcell. A significant interaction was found between irradiance and water flow for the increase in buoyant weight, the increase in surface area, and specific skeletal growth rate, indicating that flow velocity becomes more important for coral growth with increasing irradiance levels. Enhancement of coral growth with increasing water flow can be explained by increased net photosynthetic rates. Additionally, the need for costly photo-protective mechanisms at low flow regimes could explain the differences in growth with flow
Is there a cybercriminal personality? Comparing cyber offenders and offline offenders on HEXACO personality domains and their underlying facets
Cyberspace creates opportunities for new forms of crime that may be related to specific personality characteristics of offenders. Few studies have investigated the personality characteristics of cyber offenders. We address this gap by comparing a judicial sample of 261 suspects of cyber-dependent crime, 260 suspects of offline crime, and a community sample of 512 participants on the HEXACO personality domains and their underlying facets. This provides a nuanced picture of the cybercriminal personality and could provide information for prevention and intervention programs. Results indicate that, compared to suspects of offline crime, suspected cyber offenders score significantly lower on extraversion and significantly higher on conscientiousness and openness to experience. Cyber offenders are more similar to community participants on these main personality domains. With regard to the underlying facets, suspected cyber offenders appear to be unique in their relatively high level of diligence. They are more similar to suspected offline offenders on traits that may help them perform criminal activities, such as lower levels of modesty, fearfulness, and flexibility. They are more similar to the community sample, however, on traits that may strengthen their ability or tendency to commit cyber offenses, such as higher levels of patience, perfectionism, and prudence
Health-related quality of life 14 years after preoperative short-term radiotherapy and total mesorectal excision for rectal cancer: report of a multicenter randomized trial
Evaluation of the 5th edition of the TNM classification for gastric cancer: improved prognostic value
The main change in the 5th edition (1997) of the TNM classification for gastric cancer compared to the 4th edition (1987) is the use of the number of involved nodes instead of the location of positive nodes. As a result stage grouping is also altered. A second change is the requirement for the examination of at least 15 nodes to justify the N0 status. Patients with fewer examined negative nodes are unclassifiable (Nx). Data were retrieved from a randomized trial database comparing D1 and D2 dissection and 633 curatively operated patients were included. According to the criteria of the 5th edition, 39% of the node-positive patients had another N stage compared to the 4th: 21% had a lower and 18% had a higher stage. 5-year survival rates according to the 4th edition N0, N1 and N2 groups were respectively 72%, 34% and 27%. According to the 5th edition these percentages were for the N0, N1, N2, N3 and Nx groups respectively 75%, 38%, 19%, 8% and 65%. The former 1987 N1 and N2 group were significantly split into three new N 1997 groups (P = 0.006, respectively P< 0.0005). The Cox's regression analysis showed the N 1997 classification to be the most important prognostic variable, with a higher prognostic value than N 1987. In addition, the new TNM stage was also a better prognosticator. The requirement for examining at least 15 nodes, however, could not be fulfilled in 38% of all node-negative patients and we found that a minimum of 5 consecutive negative lymph nodes is a reliable number for staging purposes. We conclude that the 5th edition of the TNM classification provides a better estimation of prognosis, however, examination of at least 15 negative regional lymph nodes is too high a threshold and 5 gives similar prognostic value. © 2001 Cancer Research Campaign http://www.bjcancer.co

Long-Term Health-Related Quality of Life in Patients With Rectal Cancer After Preoperative Short-Course and Long-Course (Chemo) Radiotherapy
AbstractBackgroundBoth preoperative short-course radiotherapy (SC-PRT) and preoperative long-course chemo radiotherapy (CRT) have shown to reduce local recurrence rates after total mesorectal excision (TME), but neither resulted in improved survival. This study compared the long-term health-related quality of life (HRQL) and symptoms between CRT and SC-PRT.MethodsPatients who were preoperatively treated with a total dose of 50.0 to 50.4 Gy for locally advanced rectal cancers were identified from 2 hospital registries. Starting from 2011, all patients who were disease-free in the study population (n = 105) were sent a HRQL-questionnaire composed of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and questions on bowel and urinary function. Patients who underwent SC-PRT in the TME trial were used as a reference group.ResultsHRQL results from 85 patients receiving CRT (81.0%), with a median follow-up time of 58 months, were compared with the results of patients who underwent SC-PRT (n = 306). Apart from more nausea and vomiting reported by patients receiving CRT (mean score for CRT 5.9 vs. 1.3 for SC-PRT; P < .01; not clinically relevant) and less satisfaction with urinary function indicated by patients who received CRT (mean score for CRT 71.2 vs. 81.2 for SC-PRT; P < .01), no significant differences were found in HRQL and symptoms between patients who received CRT and SC-PRT.ConclusionsThis analysis of HRQL in patients who received CRT shows no clinically relevant differences in long-term HRQL and symptoms between patients who received CRT and SC-PRT, apart from less satisfaction with urinary function reported by patients who received CRT. These results indicate that both approaches have a comparable impact on long-term HRQL
