Geography is not Destiny. Geography, Institutions and Literacy in England, 1837-1863
Geography made rural society in the south-east of England unequal. Economies of scale in grain growing created a farmer elite and many landless labourers. In the pastoral north-west, in contrast, family farms dominated, with few hired labourers and modest income disparities. Engerman and Sokoloff (2012) argue that such differences in social structure between large plantations in the southern Americas, and family farming in the north, explain the rise of schooling in the north, and its absence in the south. We show, however, that rural literacy across England 1810-45 was not determined by geographically driven inequality. There were substantial differences in literacy by region, but driven by culture not geography.

Taking Technology to Task: The Skill Content of Technological Change in Early Twentieth Century United States
This paper presents a new picture of the labor market effects of technological change in pre-WWII United States. I show that, similar to the recent computerization episode, the electrification of the manufacturing sector led to a "hollowing out" of the skill distribution whereby workers in the middle of the distribution lost out to those at the extremes. To conduct this analysis, a new dataset detailing the task composition of occupations in the United States for the period 1880-1940 was constructed using information about the task content of over 4,000 occupations from the Dictionary of Occupational Titles (1949). This unique data was used to measure the skill content of electrification in U.S. manufacturing. OLS estimates show that electrification increased the demand for clerical, numerical, planning and people skills relative to manual skills while simultaneously reducing relative demand for the dexterity-intensive jobs which comprised the middle of the skill distribution. Thus, early twentieth century technological change was unskill-biased for blue collar tasks but skill-biased on aggregate. These results are in line with the downward trend in wage differentials within U.S. manufacturing up to 1950. To overcome any threat to the exogeneity of the electricity measure, due for example to endogenous technological change, 2 instrumental variable strategies were developed. The first uses cross-state differences in the timing of adoption of state-level utility regulation while the second exploits differences in state-level geography that encouraged the development of hydro-power generation and thus made electricity cheaper. The results from these regressions support the main conclusions of the paper.Technological change, skill bias
Returns to education in criminal organizations: Did going to college help Michael Corleone?
Is there any return to education in criminal activities? This paper is one of the first to investigate whether education has not only a positive impact on legitimate, but also on illegitimate activities. We use as a case study one of the longest running criminal corporations in history: the Italian-American mafia. Its most successful members were capable businessmen, orchestrating crimes that required abilities that might be learned at school: extracting the optimal rent when setting up a racket, weighting interests against default risk when starting a loan sharking business or organizing supply chains, logistics and distribution when setting up a drug dealing system. We address this question by comparing mobsters to a variety of samples drawn from the United States 1940 Population Census, including a sample of their closest (non-mobster) neighbors. We document that mobsters have one year less education than their neighbors on average. We find that mobsters have significant returns to education of 7.5â8.5% , which is only slightly smaller than their neighbors and 2â5 percentage points smaller than for U.S.-born men or male citizens. Mobster returns were consistently about twice as large as a sample of Italian immigrants or immigrants from all origin countries. Within that, those charged with complex crimes including embezzlement and bookmaking have the highest returns. We conclude that private returns to education exist even in the illegal activities characterized by a certain degree of complexity as in the case of organized crime in mid-twentieth century United States
A systematic review protocol to identify the key benefits and efficacy of nature-based learning in outdoor educational settings
Outdoor Learning in natural environments is a burgeoning approach in the educational sector. However, the evidence-base of research has not kept pace with teacher perceptions and increased practitioner usage. Anecdotal evidence and formal research suggest the significant health and wellbeing benefits of nature connection. Offering low-cost, non-invasive pedagogical solutions to public health challengesâparticularly around mental health, wellbeing, physical literacy, and increasing physical activityâthe pedagogical benefits of Outdoor Learning are yet to be fully enunciated. The proposed systematic review will search for studies across eight academic databases which measure the academic and socio-emotional benefits of Outdoor Learning, with a focus on school-aged educational settings. Using the inclusion criteria set out in this paper (and registered with PROSPERO: CRD42020153171), relevant studies will be identified then summarised to provide a synthesis of the current literature on Outdoor Learning. The goal of this review is to document the widespread international investigation into Outdoor Learning and its associated benefits for development, wellbeing, and personal growth. The systematic review will provide insights for teacher-training institutions, educational policy makers, and frontline teachers to improve the learning experiences of future students
Supporting Aboriginal Community Controlled Health Services to deliver alcohol care : Protocol for a cluster randomised controlled trial
Introduction Indigenous peoples who have experienced colonisation or oppression can have a higher prevalence of alcohol-related harms. In Australia, Aboriginal Community Controlled Health Services (ACCHSs) offer culturally accessible care to Aboriginal and Torres Strait Islander (Indigenous) peoples. However there are many competing health, socioeconomic and cultural client needs.
Methods and analysis A randomised cluster wait-control trial will test the effectiveness of a model of tailored and collaborative support for ACCHSs in increasing use of alcohol screening (with Alcohol Use Disorders Identification Test-Consumption (AUDIT-C)) and of treatment provision (brief intervention, counselling or relapse prevention medicines).
Setting Twenty-two ACCHSs across Australia.
Randomisation Services will be stratified by remoteness, then randomised into two groups. Half receive support soon after the trial starts (intervention or âearly supportâ); half receive support 2âyears later (wait-control or âlate supportâ).
The support Core support elements will be tailored to local needs and include: support to nominate two staff as champions for increasing alcohol care; a national training workshop and bimonthly teleconferences for service champions to share knowledge; onsite training, and bimonthly feedback on routinely collected data on screening and treatment provision.
Outcomes and analysis Primary outcome is use of screening using AUDIT-C as routinely recorded on practice software. Secondary outcomes are recording of brief intervention, counselling, relapse prevention medicines; and blood pressure, gamma glutamyltransferase and HbA1c. Multi-level logistic regression will be used to test the effectiveness of support.
Ethics and dissemination Ethical approval has been obtained from eight ethics committees: the Aboriginal Health and Medical Research Council of New South Wales (1217/16); Central Australian Human Research Ethics Committee (CA-17-2842); Northern Territory Department of Health and Menzies School of Health Research (2017-2737); Central Queensland Hospital and Health Service (17/QCQ/9); Far North Queensland (17/QCH/45-1143); Aboriginal Health Research Ethics Committee, South Australia (04-16-694); St Vincentâs Hospital (Melbourne) Human Research Ethics Committee (LRR 036/17); and Western Australian Aboriginal Health Ethics Committee (779).

What future/s for outdoor and environmental education in a world that has contended with COVID-19?
This is an unusual article in that it brings together the perspectives of many on this journalâs editorial board, around the issue of contending with COVID-19. Twenty statements showcase a range of thoughts and experiences, highlighting the differences and similarities in the way the pandemic is impacting on the educational practice of outdoor and environmental education. The future is not yet written, of course, so it is worth thinking about how the current moment may impact on the months and years to come. The aim of this article is to influence and support such thinking
Proximal adductor avulsions are rarely isolated but usually involve injury to the PLAC and pectineus: Descriptive MRI findings in 145 athletes
Purpose The purpose of the study is to review the MRI findings in a cohort of athletes who sustained acute traumatic avulsions of the adductor longus fibrocartilaginous entheses, and to investigate related injuries namely the pyramidalis- anterior pubic ligament - adductor longus complex (PLAC). Associated muscle and soft tissue injuries were also assessed. Methods The MRIs were reviewed for a partial or complete avulsion of the adductor longus fibrocartilage, as well as continuity or separation of the adductor longus from the pyramidalis. The presence of a concurrent partial pectineus tear was noted. Demographic data was analysed. Linear and logistic regression was used to examine associations between injuries. Results The mean age was 32.5 (SD 10.9). The pyramidalis was absent in 3 of 145 patients. 85 of 145 athletes were professional and 52 competed in the football Premier League. 132 had complete avulsions and 13 partial. The adductor longus was in continuity with pyramidalis in 55 athletes, partially separated in seven and completely in 81 athletes. 48 athletes with a PLAC injury had a partial pectineus avulsion. Six types of PLAC injuries patterns were identified. Associated rectus abdominis injuries were rare and only occurred in five patients (3.5%). Conclusion The proximal adductor longus forms part of the PLAC and is rarely an isolated injury. The term PLAC injury is more appropriate term. MRI imaging should assess all the anatomical components of the PLAC post-injury, allowing recognition of the differentpatterns of injury
Frequent mechanical stress suppresses proliferation of mesenchymal stem cells from human bone marrow without loss of multipotency
Mounting evidence indicated that human mesenchymal stem cells (hMSCs) are responsive not only
to biochemical but also to physical cues, such as substrate topography and stiffness. To simulate the
dynamic structures of extracellular environments of the marrow in vivo, we designed a novel surrogate
substrate for marrow derived hMSCs based on physically cross-linked hydrogels whose elasticity can
be adopted dynamically by chemical stimuli. Under frequent mechanical stress, hMSCs grown on
our hydrogel substrates maintain the expression of STRO-1 over 20 d, irrespective of the substrate
elasticity. On exposure to the corresponding induction media, these cultured hMSCs can undergo
adipogenesis and osteogenesis without requiring cell transfer onto other substrates. Moreover,
we demonstrated that our surrogate substrate suppresses the proliferation of hMSCs by up to 90%
without any loss of multiple lineage potential by changing the substrate elasticity every 2nd days.
Such âdynamic in vitro nicheâ can be used not only for a better understanding of the role of dynamic
mechanical stresses on the fate of hMSCs but also for the synchronized differentiation of adult stem
cells to a specific lineage
