Public Attitudes Toward Crime and Incarceration in Finland
The following paper provides insights into Finlandās criminal justice system and discusses the policies that emphasize using prison for rehabilitation, not merely for punishment. These methods of prevention and rehabilitation, in conjunction with correctional and educational staff within and outside the prison walls, have contributed to consistently low recidivism rates in Finland. This study discusses many ideological similarities between public opinions towards criminals and crime in Finland and the United States. Like Americans, Finns are intolerant of crime and violence, yet open to the idea of alternative forms of punishment, especially for non-violent and juvenile offenders. People in both countries tend to believe criminals are not born into a criminal life and that societal factors play a role in creating criminal behavior. This study sheds light on both the public support for ex-offendersā rehabilitation in Finland and the extent to which Americans support alternative forms of punishment. It also provides a narrative of the disconnect between public opinion and what public officials think public opinion is
Cellular innate immune responses to lung resection via video-assisted thoracospic surgery (VATS) and thoracotomy: predictors of post-operative pneumonia
BACKGROUND AND OBJECTIVES: The pathophysiology of post-operative pneumonia
following lung resection is poorly understood despite it being the most common
complication which may lead to death. The role of the acute inflammatory response
following lung resection, in particular innate immune cells, was investigated and used to
identify biomarkers for post-operative pneumonia. Comparison of inflammatory
responses to resection undertaken by video-assisted thorascopic surgery (VATS) and
thoracotomy was also evaluated.METHODS: Patients undergoing lung resection for suspected bronchogenic carcinoma
were recruited. Objective pre-defined criteria were used to diagnose pneumonia.
Bronchoalveolar lavage (BAL) was conducted in the contra-lateral lung pre- and post-operatively to measure cellular composition and cytokines. Blood was sampled preoperatively
and 6-, 24- and 48-hours post-operatively primarily to assess neutrophil
phagocytic capacity, monocyte subsets, monocyte cytokine responses to
lipopolysaccharide (LPS) stimulation and serum cytokine responses. Exhaled nitric
oxide (eNO) was also measured at these time points. Patient groups were compared
using paired or student t-tests together with ANOVA/ANCOVA modelling. The
predictive strength of the biomarkers identified was tested.14 patients developed pneumonia. Pre-operatively, a blood neutrophil count above
5.04x10ā¹/L had a relative risk (RR) for pneumonia of 3.3 (95% confidence interval
(CI95) 1.1-10.1), and a BAL cell count of greater than 1.04x10āµ/ml had a RR of 3.4 (CI95
1.3-9.0), whilst LPS-stimulated monocyte secretion of IL-12 of less than 0.15 pg/ml/pg
protein had a RR of 3.0 (CI951.2-7.3). At 24 hours post-operatively, LPS-stimulated
release from monocytes of IL-10 greater than 1.99 pg/ml/pg protein (RR 4.1, CI95 1.3-
12.3) and IL-6 greater than 414 pg/ml/pg protein (RR 3.1, CIāā
1.2-8.1) were predictive
of pneumonia.CONCLUSION: Lung resection is associated with significant early pro- and anti-inflammatory responses. VATS resection invoked significantly lower levels of serum
cytokines and albumin changes compared with thoracotomy suggesting VATS
lobectomy should be the surgical treatment strategy of choice for early stage lung
cancer. No difference in neutrophil function or monocyte function was however
observed between the surgical groups. Clinical benefits of this reduced inflammation
need to be evaluated in a larger cohort of patients. Relative pre-operative leucocytosis in
blood and BAL together with monocyte hyper-responsiveness in the early post-operative period is associated with the development of pneumonia. These findings
warrant further investigation for their predictive power in accurately identifying post-operative pneumonia. Ultimately, they may be incorporated into a risk stratification
model enabling targeted prophylactic or earlier therapeutic intervention.RESULTS: 40 patients were recruited. 26 patients (65%) underwent major lung resection
using VATS and 14 (35%) thoracotomy. There was a post-operative blood monocytosis
(p<0.0005) with an absolute expansion of classical and intermediate monocytes
(p=0.001) and a relative fall in non-classical monocytes (p<0.005). Post-operatively
blood monocytes became more pro-inflammatory with an overall significant increase in
IL-8 (p=0.034) and TNF-Ī± (p=0.028) together with an increase in IL-6 (p=0.028) and
IL-10 by 48 hours (p=0.010). VATS was associated with a smaller release of IL-10 only
(p=0.011). There was a general trend towards post-operative reduction in neutrophil
phagocytosis of zymosan (in suspension) on ANOVA modelling (p=0.047). Lung
2
resection led to an increase in serum cytokines IL-6, IL-8 and IL-10 which peaked at
24hrs before falling (p<0.0005). ANOVA modelling confirmed significantly lower
levels of serum cytokines in VATS patients compared with thoracotomy (p=0.026 for
IL-6, p=0.018 for IL-8 p=0.047 for IL-10). No significant post-operative change was
found for IL-1Ć, TNF-Ī± and IL-12p70 (p>0.05). Bronchoalveolar lavage fluid (BALF)
and blood samples demonstrated a relative post-operative leucocytosis due principally
to neutrophilia. A relative blood lymphopenia and thrombocytopenia developed postĀ¬
operatively (p<0.0005). VATS was associated with a lower fall in serum albumin
(p=0.001). BALF from the non-operated lung became more pro-inflammatory
immediately post-operatively with an increase in IL-6 (p<0.0005), IL-8 (p=0.017), IL-
10 (p=0.018) and IL-ip (p=0.002). eNO tended to fall post-operatively which reached
significance at 48 hrs (p=0.029)

Meeting Report: Biomedical Research Conference
This meeting brought together staff from the Department of Life Sciences at Anglia Ruskin University and the 150 final-year BSc (Hons) Biomedical Science students taking the āCurrent Advances in Biomedical Scienceā module led by Richard Jones. The module aimed to promote studentsā career prospects and interest in exciting research through employability, studentship and biomedical research conference days at Anglia Ruskin University (ARU) in semester 2, 2014. The venue for all three conference days was the Mumford Theatre at ARUās Cambridge Campus. The Mumford Theatre has excellent acoustics and normally hosts theatre companies. Knowledge accumulated during these days was assessed at the end of the module using a 1 hour written examination
Control theory for principled heap sizing
We propose a new, principled approach to adaptive heap sizing based on control theory. We review current state-of-the-art heap sizing mechanisms, as deployed in Jikes RVM and HotSpot. We then formulate heap sizing as a control problem, apply and tune a standard controller algorithm, and evaluate its performance on a set of well-known benchmarks. We find our controller adapts the heap size more responsively than existing mechanisms. This responsiveness allows tighter virtual machine memory footprints while preserving target application throughput, which is ideal for both embedded and utility computing domains. In short, we argue that formal, systematic approaches to memory management should be replacing ad-hoc heuristics as the discipline matures. Control-theoretic heap sizing is one such systematic approach

STATURE AND LOAD AFFECT THE WALK TO RUN TRANSITION SPEED
Military personnel are often required to march āin-stepā while carrying heavy loads. For example, the two speeds required to complete the role fitness test for the British Army are close to the preferred walking speed and preferred walk-to-run transition speed (PTS) for healthy adults when unloaded. PTS depends on anthropometry, including stature. Walking at speeds markedly different to PTS has been associated with increased metabolic cost and increased joint loading. There is also limited research into how this PTS is affected by load carriage. To minimise the risk of injury, there is a need to understand how load carriage affects PTS. This study found PTS for male and female personnel decreased with increased load carried, and that female personnel tended to transition from walking to running earlier than male personnel. The relationship between PTS and stature became more positive as load increased, irrespective of sex. Due to the association between deviating from preferred walking gait and increases in joint loading, these findings may have implications for the risk of injury in military personnel who are required to march āin-stepā
