The Reality of Measuring Human Service Programs: Results of a Survey

In the summer of 2013, Idealware created and distributed a survey to learn how human service organizations from their own mailing list are actually using technology to measure and evaluate the outcomes of their programs. The suvey looked at a general overview of outcomes measurement and program evaluation topics, from how frequently they look at data and how much time they spend doing so to what types of metrics the organizations were tracking. To further understand the realities of measuring program effectiveness, Idealware conducted a site visit and interview of three human service organizations in Portland, Maine. The results clearly show that the respondents are struggling to measure their programs

‘They are doing it because they love it’: U.S. and English fan perceptions of women footballers as ‘role models’

We draw from 102 interviews with American and English adults who attended the 2019 Women’s World Cup to examine how fans perceive women footballers as ‘role models’, with attention to the operations of gender ideology. Despite the recent professionalization and commercialization of women’s football, there is a dearth of research on fan perspectives of players as role models. Our findings show that most fans perceive role modelling as women’s accessibility and authenticity in interaction. Fans naturalize women’s often uncompensated labor as role models through a supposed love for their sport and desire to see its future growth, endorsing a gender essentialist view of women as notably caring and giving in comparison to men. However, a minority of fans embrace a more critical view by identifying role modelling as an expectation placed disproportionately on women within an already unequal resource environment. We conclude that role modelling is a gendered expectation for elite women footballers and that fans can be a source of pressure towards its enactment

Re-approaching Celts: Origins, Society, and Social Change

AbstractThis work re-approaches the origins of “the Celts” by detailing the character of their society and the nature of social change in Europe across 700–300 BC. A new approach integrates regional burial archaeology with contemporary classical texts to further refine our social understanding of the European Iron Age. Those known to us as “Celts” were matrifocal Early Iron Age groups in central Gaul who engaged in social traditions out of the central European salt trade and became heavily involved in Mediterranean politics. The paper focuses on evidence from the Hallstatt–La Tène transition to solve a 150-year-old problem: how the Early Iron Age “Celts” became the early La Tène “Galatai,” who engaged in the Celtic migrations and the sacking of Rome at 387 BC.</jats:p

Why the Patient-Made Term 'Long Covid' is needed

The patient-made term ‘Long Covid’ is, we argue, a helpful and capacious term that is needed to address key medical, epidemiological and socio-political challenges posed by diverse symptoms persisting beyond four weeks after symptom onset suggestive of coronavirus disease 2019 (COVID-19). An international movement of patients (which includes all six authors) brought the persistence and heterogeneity of long-term symptoms to widespread visibility. The same grassroots movement introduced the term ‘Long Covid’ (and the cognate term ‘long-haulers’) to intervene in relation to widespread assumptions about disease severity and duration. Persistent symptoms following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are now one of the most pressing clinical and public health phenomena to address: their cause(s) is/are unknown, their effects can be debilitating, and the percentage of patients affected is unclear, though likely significant. The term ‘Long Covid’ is now used in scientific literature, the media, and in interactions with the WHO. Uncertainty regarding its value and meaning, however, remains. In this Open Letter, we explain the advantages of the term ‘Long Covid’ and bring clarity to some pressing issues of use and definition. We also point to the importance of centring patient experience and expertise in relation to ‘Long Covid’ research, as well as the provision of care and rehabilitation.</ns4:p

A controlled study of cold dust content in galaxies from z=0−2z=0-2

At $z=1-3$, the formation of new stars is dominated by dusty galaxies whose far-IR emission indicates they contain colder dust than local galaxies of a similar luminosity. We explore the reasons for the evolving IR emission of similar galaxies over cosmic time using: 1) Local galaxies from GOALS $(L_{\rm IR}=10^{11}-10^{12}\,L_\odot)$; 2) Galaxies at $z\sim0.1-0.5$ from the 5MUSES ($L_{\rm IR}=10^{10}-10^{12}\,L_\odot$); 3) IR luminous galaxies spanning $z=0.5-3$ from GOODS and Spitzer xFLS ($L_{\rm IR}>10^{11}\,L_\odot$). All samples have Spitzer mid-IR spectra, and Herschel and ground-based submillimeter imaging covering the full IR spectral energy distribution, allowing us to robustly measure $L_{\rm IR}^{\rm\scriptscriptstyle SF}$, $T_{\rm dust}$, and $M_{\rm dust}$ for every galaxy. Despite similar infrared luminosities, $z>0.5$ dusty star forming galaxies have a factor of 5 higher dust masses and 5K colder temperatures. The increase in dust mass is linked with an increase in the gas fractions with redshift, and we do not observe a similar increase in stellar mass or star formation efficiency. $L_{160}^{\rm\scriptscriptstyle SF}/L_{70}^{\rm\scriptscriptstyle SF}$, a proxy for $T_{\rm dust}$, is strongly correlated with $L_{\rm IR}^{\rm\scriptscriptstyle SF}/M_{\rm dust}$ independently of redshift. We measure merger classification and galaxy size for a subsample, and there is no obvious correlation between these parameters and $L_{\rm IR}^{\rm \scriptscriptstyle SF}/M_{\rm dust}$ or $L_{160}^{\rm\scriptscriptstyle SF}/L_{70}^{\rm\scriptscriptstyle SF}$. In dusty star forming galaxies, the change in $L_{\rm IR}^{\rm\scriptscriptstyle SF}/M_{\rm dust}$ can fully account for the observed colder dust temperatures, suggesting that any change in the spatial extent of the interstellar medium is a second order effect.Comment: Accepted for publication in ApJ. 21 pages, 11 figure

Environmental tipping points and food system dynamics: Main report

First paragraph: Environmental tipping points occur when there are step changes in the way the biophysical world works &ndash; whether loss of soil fertility, collapse of a fishing stock, or sudden changes in weather patterns, such as those that caused the grasslands in North Africa to become deserts, 6000 years ago. These non-linear shifts arise following a critical degree of change, resulting from either many small cumulative changes or one large shock, &ldquo;tipping&rdquo; the system over a threshold and into a new stable state. Entering an alternative stable state is associated with a change to system function, usually being difficult to reverse or &ldquo;tip&rdquo; back into the original state. Increasingly we recognise that human-environment interactions are affecting the likelihood that critical thresholds for tipping points will be crossed, leading to step-changes in the provision of environmental goods and services, and impacting upon food security

The Government-led initiative for liquified petroleum gas (LPG) scale-up in Cameroon: programme development and initial evaluation

In 2016, the government of Cameroon, a central African country heavily reliant on wood fuel for cooking, published a Masterplan for increasing primary use of LPG from 20% to 58% of households by 2035. Developed via a multi-sectoral committee with support from the Global LPG Partnership, the plan envisages a 400 million Euro investment program to 2030, focused on increasing LPG cylinder numbers, key infrastructure, and enhanced regulation. This case study describes the Masterplan process and investment proposals and draws on community studies and stakeholder interviews to identify factors likely to impact on the planned expansion of LPG use

Hillfort gate-mechanisms: A contextual, architectural reassessment of Eddisbury, Hembury, and Cadbury hillforts

This paper offers a typology of hillfort gate-mechanisms, and a developed understanding of temporal depth in hillfort architecture – via applied contextual analysis. Rediscovery of the Eddisbury hillfort archive revealed three iron gate-mechanisms. To situate these rare objects, detailed analyses of entrance architecture and stratigraphy was conducted – for Eddisbury and parallels (Hembury, South Cadbury) – enabling new sequences, resolution of the Mid-Late Cadbury sequence, and reconstruction of the Cadbury gate-fittings. Crucially, Bayesian analysis of C-14 dates from Eddisbury confirm a 400 BC date for developed hillforts. Eddisbury’s gate-mechanisms are revealed as the earliest in Europe, with Roman adoption of Iron Age technology
