People Like Me Don’t Belong in Places Like This. Creating and Developing a Community of Learners beyond the Prison Gates
It is widely accepted that individuals with criminal convictions experience multiple disadvantage and deprivation, and, as a result, are considered least likely to progress to higher education (Unlock, 2018). The risk-adverse nature of higher education application processes further compound such disadvantage, even though there is no evidence to suggest that screening for criminal convictions increase campus safety (Centre for Community Alternatives, 2010). Drawing upon ethnographic data, the discussion critically reflects upon the development of one situated Learning Together initiative based within a University in the north-west of England. In doing so, the discussion highlights a series of emerging opportunities and competing contradictions that span over three key developmental areas: creation, progress and maintenance. We anticipate that the findings will go some way in opening up a wider debate about the sustainability of initiatives that seek to create dynamic educational partnerships between the higher education sector and criminal justice system more broadly
The Non-homogeneous Poisson Process for Fast Radio Burst Rates
This paper presents the non-homogeneous Poisson process (NHPP) for modeling
the rate of fast radio bursts (FRBs) and other infrequently observed
astronomical events. The NHPP, well-known in statistics, can model changes in
the rate as a function of both astronomical features and the details of an
observing campaign. This is particularly helpful for rare events like FRBs
because the NHPP can combine information across surveys, making the most of all
available information. The goal of the paper is two-fold. First, it is intended
to be a tutorial on the use of the NHPP. Second, we build an NHPP model that
incorporates beam patterns and a power law flux distribution for the rate of
FRBs. Using information from 12 surveys including 15 detections, we find an
all-sky FRB rate of 586.88 events per sky per day above a flux of 1 Jy (95\%
CI: 271.86, 923.72) and a flux power-law index of 0.91 (95\% CI: 0.57, 1.25).
Our rate is lower than other published rates, but consistent with the rate

Pd-Catalyzed One-Pot Borylation/Intramolecular Asymmetric Arylation on α-Ketiminoamides: Innovative Approach to Chiral 3-Amino-2-oxindoles
3-Amino-2-oxindole derivatives are a common framework found in many natural products and medicinal compounds and thus their synthesis is of significant importance. We report for the first time a one-pot approach for the synthesis of these compounds, using a borylation/intramolecular asymmetric arylation sequence starting from ortho-bromo-alpha-ketimino amide derivatives. Pd(OAc)(2) was used as the pre-catalyst along with (R)-BINAP as the chiral source. We successfully obtained a family of 3-phenyl-3-(aryl-amino)-indolin-2-one derivatives (11 in total) with excellent yields (up to 98%) and enantioselectivities of up to 76% ee. The reaction is versatile and tolerant of a wide range of functional groups
Anticipatory eye movements evoked after active following versus passive observation of a predictable motion stimulus.
We used passive and active following of a predictable smooth pursuit stimulus in order to establish if predictive eye movement responses are equivalent under both passive and active conditions. The smooth pursuit stimulus was presented in pairs that were either ‘predictable’ in which both presentations were matched in timing and velocity, or ‘randomized’ in which each presentation in the pair was varied in both timing and velocity. A visual cue signaled the type of response required from the subject; a green cue indicated the subject should follow both the target presentations (Go-Go), a pink cue indicated that the subject should passively observe the 1st target and follow the 2nd target (NoGo-Go), and finally a green cue with a black cross revealed a randomized (Rnd) trial in which the subject should follow both presentations. The results revealed better prediction in the Go-Go trials than in the NoGo-Go trials, as indicated by higher anticipatory velocity and earlier eye movement onset (latency). We conclude that velocity and timing information stored from passive observation of a moving target is diminished when compared to active following of the target. This study has significant consequences for understanding how visuomotor memory is generated, stored and subsequently released from short-term memory
Approaches to inform redevelopment of brownfield sites: an example from the Leeds area of the West Yorkshire coalfield, UK
Government-led regeneration schemes and policies encouraging the use of brownfield land present a challenge, particularly in coalfield areas. Coalfields have typically experienced multiple phases of development and can be susceptible to a suite of problematic ground conditions that may be rooted in the near-surface geology or result from anthropogenic activity. Such problems, related to the nature of void backfill, undermined and unstable ground and the presence of contaminated land in the near-surface, may deter investment in the very areas earmarked for redevelopment. An understanding of previous developments within coalfields is required to identify potential geological hazards, so that regeneration proposals include measures that address these issues. Public records of landfill and site investigations, and minerals exploration including opencast mine plans can reveal the distribution, thickness and high-level descriptions of fill materials, although the coverage of data typically precludes a comprehensive analysis of entire cities. The best way to show the spatial distribution of fill materials is currently as a two dimensional national/regional scale dataset. Depending on the distribution of data points, however, 3D modelling can be possible, which is much more detailed and accurate. Focusing on the heavily urbanised county of West Yorkshire in northern England, the assessment of opencast coal mining on the landscape and benefits of quantifying the impact are discussed. We demonstrate how certain types of publicly available data allow a greater understanding of the interaction between human activity and natural superficial and bedrock geology. If successful, this approach can help lessen the impact of delays and increased financial costs caused by unforeseen ground conditions
