Emma Saunders-Hastings: Philanthropy and Democracy
Overview & Shownotes
Inquiries around the ethics of philanthropy might seem pretty cut-and-dry at first glance. Are the people receiving donations better off than they were before they received help? Even if the answer to that question is yes, political theorist Emma Saunders-Hastings argues that itâs not the only critical question we should be asking about philanthropy. On this episode of the podcast, we discuss her new book, Private Virtues, Public Vices: Philanthropy and Democratic Equality.

Femoroacetabular impingement and cam morphology: Contributions to bioarchaeology and forensic anthropology
Femoroacetabular impingement is a clinical disorder of the hip caused by premature contact between the femur and the acetabulum. A lead cause of this condition is cam morphology, additional bone growth on the anterior aspect of the femoral head. Cam morphology has been associated with physical activity due to its high prevalence rates in athletes compared to non-athletes. A link between non-metric traits of the femur, particularly; Poirierâs facets, plaque and cribra, and cam morphology has been suggested due to their shared location and suggested aetiology. Osteitis pubis, an overuse syndrome of the pubic symphysis, is believed to be a compensatory injury of femoroacetabular impingement. The overall aim of this study was to determine the contributions of femoroacetabular impingement to the disciplines of bioarchaeology and forensic anthropology, with regards to femoral non-metric traits analysis, activity reconstruction and awareness of conditions that may affect the formation of biological profiles. To achieve this, this study aimed to establish if there is a link between cam morphology and non-metric traits of the anterior aspect of the femur. This would provide further understanding of the respective/joint aetiologies through the use of multidisciplinary literature. It also aimed to determine if the development of cam morphology is linked to occupational physical activity. Additionally, this study looked to determine if any osseous changes are present in individuals with femoroacetabular impingement in association with cam morphology, to allow the identification of symptomatic individuals when the presence of clinical information is not available. Finally, it also aimed to determine if there is a link between cam morphology and osteitis pubis at the pubic symphysis. This would contribute to both bioarchaeology and forensic anthropology, by highlighting a condition which may impact an area commonly used for the age estimation. Two skeletal collections, the Wharram Percy collection and the LuĂs Lopes Identified Skeletal Collection, and a clinical comparison sample were utilised. These collections were selected due to presence of contextual information regarding lifestyle and occupation in different forms. The clinical comparison sample consisted of 3D volume ii rendered CT models of individuals being investigated for femoroacetabular impingement and a control sample. Non-metric traits of the femur and commonly used clinical measures to determine the presence of cam morphology were recorded on all samples. Recording criteria for osteitis pubis was developed and applied to the pubic symphysis of the two skeletal collections. Comparisons of these measurements were made within and between the samples. The results of this study have shown there is a link between Poirierâs facets and plaque with cam morphology. Through the use of contextual information, it is recommended this association is a functional adaptation. There was no association between cam morphology, alpha angle size and occupational physical activity groups in adults. It is suggested cam morphology is therefore a better indicator of activity levels, or other extrinsic factors, requiring additional stability at the hip during skeletal maturation. No clear osseous indicators of the presence of FAI due to cam morphology were identified. Therefore, it is not possible to identify symptomatic individuals through skeletal changes alone. There was also limited evidence of a link between osteitis pubis traits and alpha angle size. Although eburnation could be an indicator for the later stages of this condition, however, there is the requirement for further study to confirm this
Micro-Analytical Studies of the Petrogenesis of Silicic Arc Magmas in the Taupo Volcanic Zone and Southern Kermadec Arc, New Zealand
The petrogenesis of silicic arc magmas is controversial with end-member models of fractional crystallisation and crustal anatexis having been invoked. A prime example of this is the archetypical continental Taupo Volcanic Zone and the adjacent oceanic Kermadec Arc. Insights into the genesis and timescales of magmatic processes of four continental rhyolitic magmas (Whakamaru, Oruanui, Taupo and Rotorua eruptives) and an oceanic (Healy seamount) rhyodacitic magma are documented through micro-analytical chemical studies of melt inclusions and crystal zonation of plagioclase and quartz. Electron probe microanalysis, laser ablation inductively coupled plasma mass spectrometry and
Fourier transform infrared spectroscopy have been used to measure major, trace and volatile element concentrations, respectively, of melt inclusions and crystals. Melt inclusions are high silica (e.g. 74 - 79 wt%) irrespective of arc setting and display a wide range of trace element compositions (e.g. Sr = 17 - 180 ppm). Taupo Volcanic Zone melt inclusions exhibit higher K2O and Ce/Yb relative to Healy melt inclusions reflecting the assimilation of continental lithosphere. Quantitative trace element modelling of melt inclusion compositions: (a) demonstrates that magma genesis occurred through 62 - 76% fractional crystallisation at Healy whereas assimilation of continental lithosphere (greywacke) in addition to 60 - 80% fractional crystallisation is required for the Taupo Volcanic Zone magmas; and (b) suggests the presence of crystal mush bodies beneath silicic magma chambers in both continental and oceanic arc
environments. Water concentrations of melt inclusions ranged between 1.4 - 5.1 wt% for the Whakamaru, Taupo and Healy samples. However, the inconsistency in the measured molecular water to hydroxyl concentrations of melt inclusions relative to those determined experimentally for groundmass rhyolitic glasses provide evidence for the degassing of inclusions prior to quenching, by diffusion of hydroxyl groups through the crystal host. Thus, partial pressures of water estimated from the inclusions and inferred depths of the crystallising magma bodies are underestimated. Chemical profiles of mineral zonation, however, indicate a more complex origin
of silicic melts than simple fractionation and assimilation. For example, trace element modelling of Whakamaru plagioclase suggests that the three distinct textural plagioclase populations present in Whakamaru samples crystallised from four physiochemically discrete silicic melts. This modelling indicates a strong
petrogenetic link between andesitic and silicic magmas from the chemical variation of selected Whakamaru plagioclase crystals possessing high anorthite (45-60 mol %) cores and low anorthite (~ 30 mol %) rim compositions and the interaction of greywacke partial melts. Furthermore, Sr diffusion modelling of core-rim interfaces of the same plagioclase crystals indicate the amalgamation of the magma chamber occurred continuously over the 15,000 years preceding the
climactic eruption. Conversely, the major element zonation of Taupo plagioclases implies magma genesis occurred solely through assimilation and
fractional crystallisation without the incorporation of evolved crystal mush magmas, indicating a spectrum of magmatic processes are occurring beneath the Taupo Volcanic Zone with each eruption providing only a snapshot of the
petrogenesis of the Taupo Volcanic Zone
Chipping away at globalisation: transnational labour organising in the semiconductor industry
In an age of globalised, highly competitive, volatile and financialised markets, the
question of how to effectively organise workers to win concrete improvements in
their working lives is increasingly difficult to answer. This thesis builds on four years
of action-research, which supported eight unions in one company spread across five
countries, to coordinate some of their actions and to push for a Global Framework
Agreement to secure workersâ associational freedoms. It highlights the difficulties
that workers face when trying to collaborate across borders and argues that any
attempt to effectively study or empower trade unions at the scale of their
multinational employer must pay attention to the specific factors which condition
their agency as well as to the goals, tactics and enactments through which the ideal
of international solidarity is embodied.
The company studied produces silicon chips, employing approximately 28,000
workers across highly capital-intensive processes of research, development and chip
production in the Global North, alongside 17,000 workers in the Global South to test
and assemble the circuits. Between 2005 and 2016, the company underwent a
process of financialisation, distributing ever larger dividends to its shareholders,
whilst decreasing capital expenditure and implementing several restructuring and
layoff plans. Faced with what they saw as an existential threat to their companyâs
future, seven unions from four different countries (France, Italy, Morocco and
Malaysia) organised successful joint actions to secure greater capital investments
and the replacement of the corporationâs senior management team. Following this
campaign, these unions, joined by an eighth from Malta, created an international
network to exchange information and campaigned without success for the company
to sign a Global Framework Agreement. This attempt to organise across sites,
languages, cultures, and institutional contexts, I argue, acts as a microcosm of the
difficulties workers face in their efforts to exert power in a world characterised by
globalising and centralising production and intensified financialisation.
This thesis makes two contributions to labour geography and struggles for workersâ
rights more broadly. First, it argues that any attempt to understand these struggles
and their chances of success must be attuned to the actually-existing conditions of
building solidarity and that these conditions cross a number of spatialities and
temporalities. The unionsâ international solidarity efforts were balanced on a series
of contradictory and uneven relationships. Their members were tied to specific
national interests, and their company confronted heightened pressures of scale which reverberated across the sites. Each union reflected their membersâ experiences and
socio-spatial positionalities, whose register crossed a number of scales and each
union was threatened and/or co-opted by corporate tactics and stood by different
ideological visions. Unless scholars and activists attend to these detailed variations
and stories, practices and studies of international labour solidarity will remain an
abstract ideal, rather than placed in the grounded and âmessyâ attempt by workersâ
organisations to deal with and work across multiple differences. Second, it argues
that international efforts which focus on formal processes of rule-making at the
expense of more grassroots and militant approaches stifle international collaboration.
To sustain international collaboration, instead of an institutional and âdialogueâ-
based approach, which underplays the conflict opposing workers and their
employers, trade unions should push for ambitious demands based on shared
experiences and interests and engage in truly reciprocal forms of solidarity, rather
than semi-patronising âhelpâ models, whilst recognising that these discussions are
traversed by each unionsâ local realities and ideological stances. Ultimately, this
thesis reminds us that building a sense of collective agency at the international scale
is an iterative process, necessary but difficult, facing constant threats and changing
circumstances. In the face of a global economy managed with increasing disregard
for workersâ dignity and survival, let alone their power, it is vital that geographers
pay increased attention to the strategies, challenges, and achievements of unions both
on the ground, and, even if unsuccessful, over space
Multiple system atrophy
This is a practical guide to diagnosing and managing multiple system atrophy (MSA). We explain the newly published Movement Disorders Society Consensus Diagnostic Criteria, which include new âClinically Established MSAâ and âPossible Prodromal MSAâ categories, hopefully reducing time to diagnosis. We then highlight the key clinical features of MSA to aid diagnosis. We include a list of MSA mimics with suggested methods of differentiation from MSA. Lastly, we discuss practical symptom management in people living with MSA, including balancing side effects, with the ultimate aim of improving quality of life

Emergencies within hospital wards: An observational study of the non-technical skills of medical emergency teams
Background Medical emergency teams are essential in responding to acute deterioration of patients in hospitals, requiring both clinical and non-technical skills. This study aims to assess the non-technical skills of medical emergency teams during hospital ward emergencies and explore team members perceptions and experiences of the use non-technical skills during medical emergencies. Methods A multi-methods study was conducted in two phases. During phase one observation and assessment of non-technical skills used in medical emergencies using the Team Emergency Assessment Measure (TEAMâą) was conducted; and in the phase two in-depth interviews were undertaken with medical emergency team members. Results Based on 20 observations, mean TEAMâą ratings for non-technical skill domains were: âleadershipâ 5.0 out of 8 (±2.0); âteamworkâ 21.6 out of 28 (±3.6); and âtask managementâ 6.5 out of 8 (±1.4). The mean âglobalâ score was 7.5 out of 10 (±1.5). The qualitative findings identified three areas, âindividualâ, âteamâ and âotherâ contributing factors, which impacted upon the non-technical skills of medical emergency teams. Conclusion Non-technical skills of hospital medical emergency teams differ, and the impact of the skill mix on resuscitation outcomes was recognised by team members. These findings emphasize the importance non-technical skills in resuscitation training and well-developed processes for medical emergency teams
