الوصف: The policing approach known as Problem oriented policing (POP) was outlined by Herman Goldstein in 1979. Despite POP being shown as an effective method to reduce crime it is difficult to implement because of the high analytical burden that accompanies it. This analytical burden is centred on understanding the mechanism by which a crime took place. One of the factors that contributes to this high burden is that a lot of the required information is stored in free- text data, which has traditionally not been in a format suitable for aggregate analysis. However, advances in machine learning, in particular natural language processing, are lowering the barriers for extracting information from free-text data. This thesis explores the potential for pre-trained language models (PTMs) to efficiently unlock the information in police crime free-text data. PTMs are a new class of machine learning model that are 'pre-trained' to recognise the meaning of language. This allows the PTM to interrogate large quantities of free-text data. Thanks to this pre-training, PTMs can be adapted to specific natural language processing tasks with much less effort. Efficiently unlocking the information in the police free-text crime data should reduce the analytical burden for POP. In turn, the lower analytical burden should facilitate the wider adoption of POP. The thesis concludes that the evidence suggests PTMs are potentially an efficient method for extracting useful information from police free text data.

الوصف: The treatment of cutaneous squamous cell carcinoma in situ by Mohs micrographic surgery is currently deemed as appropriate by the Mohs Appropriate Use Criteria. However, squamous cell carcinoma in situ is a very superficial, indolent, low-risk tumor amenable to destructive and non-surgical treatments. It is uncommon for squamous cell carcinoma in situ to have progressed to invasive malignancy subsequent to definitive management. The suggestion that squamous cell carcinoma in situ on certain anatomic locations has a poorer prognosis is widely assumed but lacks an evidence base. We recommend that most primary squamous cell carcinoma in situ in non-immunosuppressed patients be scored inappropriate or uncertain for Mohs micrographic surgery by the Mohs Appropriate Use Criteria. Multiple other efficacious treatment options exist for managing squamous cell carcinoma in situ, including curettage and cryotherapy, curettage and electrodessication, and topical therapies.

الوصف: The numbers per tiller (abundance) and per unit area of ground (population density) of the dominant cereal aphids in winter wheat crops, Sitobion avenae (Fabricius) and Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) were recorded from 2000–2015. The results were used to test the hypothesis that at the population peak and 4 weeks previously, the population density of aphids in winter wheat crops ( Triticum aestivum L., Poaceae) is uniformly distributed with respect to surface area and, as a result, their abundance is high in sparse stands (SPA) where the colonizing aphids are scattered among a small number of tillers (ca. 80 m −2 ), and low in dense stands (DEN) where they are scattered among a larger number of tillers (ca. 440 m −2 ). This prediction was verified for S. avenae , the population density of which did not significantly differ between SPA and DEN stands throughout this period. This species feeds mainly on the ears, whose nutritional quality for aphids varies little with crop density and during the course of ripening. In contrast and contrary to our prediction, the population density of M. dirhodum increased throughout this period more rapidly in SPA than in DEN stands. This species lives on leaves whose quality is better and remain present for longer during the course of ripening of the crop in SPA than DEN stands. The abundance of both species was higher in SPA than in DEN stands. Greater direct damage to cereal crops can be expected when using technologies and cultivars of winter wheat that need to be planted sparsely.

الوصف: Research on pandemic domestic abuse trends has produced inconsistent findings reflecting differences in definitions, data and method. This study analyses 43,488 domestic abuse crimes recorded by a UK police force. Metrics and analytic approaches are tailored to address key methodological issues in three key ways. First, it was hypothesised that reporting rates changed during lockdown, so natural language processing was used to interrogate untapped free-text information in police records to develop a novel indicator of change in reporting. Second, it was hypothesised that abuse would change differentially for those cohabiting (due to physical proximity) compared to non-cohabitees, which was assessed via a proxy measure. Third, the analytic approaches used were change-point analysis and anomaly detection: these are more independent than regression analysis for present purposes in gauging the timing and duration of significant change. However, the main findings were largely contrary to expectation: (1) domestic abuse did not increase during the first national lockdown in early 2020 but increased across a prolonged post-lockdown period, (2) the post-lockdown increase did not reflect change in reporting by victims, and; (3) the proportion of abuse between cohabiting partners, at around 40 percent of the total, did not increase significantly during or after the lockdown. The implications of these unanticipated findings are discussed.

الوصف: Background: Melanoma disease patterns vary with patient age. Aim: To evaluate sentinel lymph node biopsy (SLNB) in managing melanoma at differing patient ages. Methods: Online prediction tools were applied to compare SLNB positivity (SLNB+ ) and survival risk at patient ages 20-80. Tübingen melanoma data were used to determine variations in the hazard ratio of SLNB+ for mortality at different patient ages. Results: Regardless of tumour thickness, predicted SLNB+ rates were markedly higher than mortality rates for 20-year-old patients. For 80-year-old patients, it is the opposite. Discussion: If 1000 20-year-olds with a 0.4 mm thickness non-ulcerated melanoma underwent SLNB, 100 would likely be positive. If all 100 were to be offered adjuvant drug therapy (ADT), fewer than three more melanoma deaths in those 1000 patients would be avoided. In total, 97 patients would have received medication they may never have needed. If 1000 80-year-olds with a 3 mm thickness non-ulcerated melanoma underwent SLNB, only 40 would likely be positive. In total, 274 patients would be predicted to die of melanoma, 245 being SLNB negative and 29 SLNB+ . ADT linked to SLNB+ could deny treatment to 89% of these high-risk patients. Limitations: The authors relied on published risk data. Conclusion: SLNB has poor specificity at predicting mortality in young melanoma patients and poor sensitivity in older patients. SLNB is not indicated in managing cutaneous melanoma for patients under 40 or over 60 years of age. Many such patients could be managed with wide local excision alone in their clinician's office-based practice. For all cutaneous melanoma patients at all ages, linking ADT to BAUSSS biomarker, (an algorithm of Breslow thickness, age, ulceration, subtype, sex and Site) rather than SLNB+ is likely more appropriate. BAUSSS provides a more accurate melanoma-specific mortality risk assessment for patients without burdening them with added surgery, hospitalization, costs or morbidity risk.
