Introduction: women’s international activism during the inter-war period, 1919-1939’
This article explains why women’s international activism in the inter-war period should be a subject of scholarly interest, and also discusses the myriad and vibrant forms it could take. For some women campaigners, international work – whether through .established national women’s movements or via separate, radical pacifist organisations – was crucial for the prevention of war and the maintenance of world peace. However, this was not the only motivation. Others were interested in the scientific or professional advantages of combining knowledge at international or transnational level. Others still were keen to exploit international links in order to further political objectives closer to home, such as the achievement of women’s suffrage, the encouragement of inter-cultural understanding between women from different ethnic, religious or linguistic backgrounds, or the promotion of conservative values, anti-communism or physical fitness within particular national or multi-national settings. Examples of all of these kinds of activism can be found in the individual contributions to this special issue
Looking for Meaning (manual) by Matthew Lipman and Ann Margaret Sharp
The philosophical exercises in this manual offer practice in generalization, classification, concept development, making comparisons, offering counterexamples, using analogies and contradiction. Reasoning skills are employed in writing exercises, and in enhancing students\u27 judgment. Discussion plans help students explore philosophical concepts central to their experience, such as friendship, families, honesty and autonomy. All reasoning skills and philosophical concepts are explained in nontechnical language.https://digitalcommons.montclair.edu/iapc_primary_schl_curriculum/1001/thumbnail.jp

Student Project Environmental influences on box blight epidemics
Calonectria pseudonaviculata and C. henricotiae are two recently differentiated fungal species responsible for box blight, a disease that threatens the Buxus genus. Infection can be introduced to gardens on new plants and is spread through the use of tools. The fungus survives on stem lesions and fallen leaves when spores are dispersed by rainsplash. In this study, 195 Calonectria UK isolates collected by the Royal Horticultural Society (RHS) Advisory Service were identified to species level. Detached stem assays were performed to assess how long stem and leaf lesions remain infectious, and their sensitivity to fungicides. A survey was also carried out at three National Trust properties on the effect of clipping on box blight distribution and severity. It was found that C. henricotiae was only present in and after 2011. C. henricotiae is more thermotolerant, and the increase in prevalence may be a result of increasing temperature and longer dry spells in the UK. Sporulation could occur multiple times on both stem and leaf lesions in humid conditions, although spore production dropped markedly after six sporulation events. Fungicides were effective at preventing spore production on stem lesions. Long dry spells may also reduce Calonectria’s ability to sporulate, leading to limited box blight spread between plants
Convective infux/glymphatic system: tracers injected into the CSF enter and leave the brain along separate periarterial basement membrane pathways
Tracers injected into CSF pass into the brain alongside arteries and out again. This has been recently termed the "glymphatic system" that proposes tracers enter the brain along periarterial "spaces" and leave the brain along the walls of veins. The object of the present study is to test the hypothesis that: (1) tracers from the CSF enter the cerebral cortex along pial-glial basement membranes as there are no perivascular "spaces" around cortical arteries, (2) tracers leave the brain along smooth muscle cell basement membranes that form the Intramural Peri-Arterial Drainage (IPAD) pathways for the elimination of interstitial fluid and solutes from the brain. 2 μL of 100 μM soluble, fluorescent fixable amyloid β (Aβ) were injected into the CSF of the cisterna magna of 6-10 and 24-30 month-old male mice and their brains were examined 5 and 30 min later. At 5 min, immunocytochemistry and confocal microscopy revealed Aβ on the outer aspects of cortical arteries colocalized with α-2 laminin in the pial-glial basement membranes. At 30 min, Aβ was colocalised with collagen IV in smooth muscle cell basement membranes in the walls of cortical arteries corresponding to the IPAD pathways. No evidence for drainage along the walls of veins was found. Measurements of the depth of penetration of tracer were taken from 11 regions of the brain. Maximum depths of penetration of tracer into the brain were achieved in the pons and caudoputamen. Conclusions drawn from the present study are that tracers injected into the CSF enter and leave the brain along separate periarterial basement membrane pathways. The exit route is along IPAD pathways in which Aβ accumulates in cerebral amyloid angiopathy (CAA) in Alzheimer's disease. Results from this study suggest that CSF may be a suitable route for delivery of therapies for neurological diseases, including CAA
Essays in spatial and labour economics
This thesis is comprised of three independent chapters on topics in spatial, labour and development economics. I focus on South Africa for which there is a rich and under-exploited set of micro-data and where the peculiar history of the country - including restricted migration and separate development along race lines - makes for a particularly interesting setting. The first chapter provides some of the first evidence on the labour market impacts of female internal migration. Merging detailed migration data from censuses and labour market data from labour force surveys, I exploit substantial time-variation in female migrant inflows into over 200 districts. To identify causal effects, I make use of the unique history of South Africa to construct a plausibly exogenous shift-share instrument for female migrant concentration based on earlier male migration flows from reserves during the Apartheid period. I find that this migration increases the employment and hours worked of high-skilled women (due to substitution in household work) and leads to a reduction in the employment of low-skilled female non-migrants (due to increased competition). The second chapter examines how minimum wage legislation influences the labour market impacts of productivity shocks. Merging district-level high resolution weather data with high frequency data from South Africa’s labour force survey, I examine how the introduction of an agricultural minimum wage affects resilience to weather shocks in the short term using a difference-in-differences approach. I find strong evidence that the substantially increased (and inflexible) wage bill after the minimum wage law leads agricultural employers to retrench formally employed workers in the wake of negative shocks (whereas agricultural employment was more resilient in the pre-law period). In the third and final chapter, I estimate the magnitude of agglomeration externalities in South Africa using a unique geo-coded panel micro-dataset where workers are tracked as they move across the country. The few studies on developing countries to date have estimated much higher agglomeration elasticities than those found in developed countries, but these studies have generally been unable to control for sorting on unobservables or to work with the ideal geographic units. Employing individual fixed effects and an instrumental variable constructed from a novel dataset on historical population settlements, my preferred estimate for regional wage elasticity is approximately 0.03 - in line with estimates for developed countries

Visitors’ Climate Change Beliefs & Perceptions of Climate-Sensitive Resources at Great Sand Dunes National Park
Abstract
Ecological consequences associated with climate change are becoming increasingly noticeable in nature-based recreation areas. Research is therefore needed to better understand nature-based recreationists’ perceptions of, attitudes towards, and behavioral responses to climate change and resource impacts in parks. This study explored strategies for assessing and responding to visitor perceptions of climate change at Great Sand Dunes National Park (GRSA), Colorado. In the summer of 2011, researchers intercepted visitors at GRSD and invited them to complete an online questionnaire. Visitors reported strong beliefs that global climate change was currently happening, but less certainty regarding the belief that human activities are influencing climate. Studies such as this may provide information for interpreters and park staff regarding climate change, and increase visitors’ understanding of climate change. Future research could expand upon this exploratory study in an effort to inform resource management decisions and develop targeted climate change visitor education programs
