Discussing atypical sexual harassment as a controversial issue in bystander programmes: One UK campus study

This research emanates from an anti-sexual violence bystander programme delivered at an English university. Fifteen students were identified through purposive and convenience sampling to take part in focus groups. Discussions emerged regarding atypical sexual harassment. There is a gap in the literature exploring sexual harassment outside of the male perpetrator and female victim narrative which this paper contributes to. This paper considers four conversational themes: ‘unwanted touching: women to men’, ‘sexual banter: women to men’, ‘sexual stereotypes: women and men’, and ‘developing stronger ethical subjectivity’. This paper recognises most sexual harassment occurs from men to women, and acknowledges criticism of focussing otherwise when resources are limited, noting this risks obscuring the enduring power differentials between the sexes. It contends that exploring a controversial issue, such as male experience of sexual harassment, might help bystander programmes by developing ethical subjectivity in undergraduate students. Exploring sexual behaviour as a spectrum may lead to counter hegemonic discourses to emerge

Global variation in anastomosis and end colostomy formation following left-sided colorectal resection

Background End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection. Methods This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model. Results In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6·9 per cent) from low-HDI, 254 (15·5 per cent) from middle-HDI and 1268 (77·6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57·5, 40·9 and 35·4 per cent; P < 0·001) and subsequent use of end colostomy (52·2, 24·8 and 18·9 per cent; P < 0·001) in low- compared with middle- and high-HDI settings. The association with colostomy use in low-HDI settings persisted (odds ratio (OR) 3·20, 95 per cent c.i. 1·35 to 7·57; P = 0·008) after risk adjustment for malignant disease (OR 2·34, 1·65 to 3·32; P < 0·001), emergency surgery (OR 4·08, 2·73 to 6·10; P < 0·001), time to operation at least 48 h (OR 1·99, 1·28 to 3·09; P = 0·002) and disease perforation (OR 4·00, 2·81 to 5·69; P < 0·001). Conclusion Global differences existed in the proportion of patients receiving end stomas after left-sided colorectal resection based on income, which went beyond case mix alone

Fragmentation of transition metal carbonyl cluster anions: Structural insights from mass spectrometry

The anionic clusters [HOs5-(Co)(15)](-), [PtRu5C(CO)(15)](2-), [Os10C-(CO)(24)](2-), [Os-17(CO)(36)](2-), [Os-20(CO)(40)](3-) [Co6C(CO)15]2-, [Pt3Ru10C2-(CO)(32)](2-) and [Pd6Ru6(CO)(24)](2-) have been analysed by energy-dependent electrospray ionisation mass spectrometry (EDESI-MS). Three main features have emerged. Firstly, carbonyl ligands are fragmented from clusters with compact metal cores in an orderly fashion, with each of the ions generated by CO loss having approximately equal intensity. Secondly. electron autodetachment takes place in multiply charged anionic clusters. but only after elimination of a large proportion of their carbonyl ligands. Thirdly, clusters with open metal cores do not undergo CO loss in an orderly fashion. but certain peaks are considerably less intense. The appearance of these low-intensity peaks is believed to signify polyhedral core rearrangements, with open clusters folding to form more compact geometries. In some cases. the gas-phase transformations observed by EDESI-MS mirror those that are known to take place in solution
