Backchannel relevance spaces

This contribution introduces backchannel relevance spaces – intervals where it is relevant for a listener in a conversation to produce a backchannel. By annotating and comparing actual visual and vocal backchannels with potential backchannels established using a group of subjects acting as third-party listeners, we show (i) that visual only backchannels represent a substantial proportion of all backchannels; and (ii) that there are more opportunities for backchannels (i.e. potential backchannels or backchannel relevance spaces) than there are actual vocal and visual backchannels. These findings indicate that backchannel relevance spaces enable more accurate acoustic, prosodic, lexical (et cetera) descriptions of backchannel inviting cues than descriptions based on the context of actual vocal backchannels only

Computational Approaches to Modeling Speaker State in the Medical Domain

Recently, researchers in computer science and engineering have begun to explore the possibility of finding speech-based correlates of various medical conditions using automatic, computational methods. If such language cues can be identified and quantified automatically, this information can be used to support diagnosis and treatment of medical conditions in clinical settings and to further fundamental research in understanding cognition. This chapter reviews computational approaches that explore communicative patterns of patients who suffer from medical conditions such as depression, autism spectrum disorders, schizophrenia, and cancer. There are two main approaches discussed: research that explores features extracted from the acoustic signal and research that focuses on lexical and semantic features. We also present some applied research that uses computational methods to develop assistive technologies. In the final sections we discuss issues related to and the future of this emerging field of research

Murphy's Law or luck of the Irish? Disparate treatment of the Irish in 19th century courts

Using data on 100 years of 19th century criminal trials at London's Old Bailey, this paper offers clear evidence of disparate treatment of Irish-named defendants and victims by English juries. We measure surname Irishness and Englishness using place of birth in the 1881 census. Irish-named defendants are 11% less likely to plea, 3% more likely to be convicted by the jury, and 16% less likely to receive a jury recommendation for mercy. These disparities are: (i) largest for violent crimes and for defendants with more distinctive Irish surnames; (ii) robust to case characteristic controls and proxies for signals associated with Irish surnames (social class, Irish county of origin, criminality); (iii) particularly visible for Irish defendants in cases with English victims; and (iv) spill-over onto English-named defendants with Irish co-defendants. Disparate treatment is first visible in the 1830s, after which it grows, then persists through to the end of the century. In particular, the gap in jury conviction rates became larger during the twenty years after the Irish Potato Famine-induced migration to London. We do not find evidence, however, that the first bombing campaign of the Irish Republican Brotherhood (in 1867 and the 1880s) further exacerbated these disparities

Molecular association and morphological characterisation of Himalopsyche larval types (Trichoptera, Rhyacophilidae)

Himalopsyche Banks, 1940 (Trichoptera, Rhyacophilidae) is a genus of caddisflies inhabiting mountain and alpine environments in Central and East Asia and the Nearctic. Of 53 known species, only five species have been described previously in the aquatic larval stage. We perform life stage association using three strategies (GMYC, PTP, and reciprocal monophyly) based on fragments of two molecular markers: the nuclear CAD, and the mitochondrial COI gene. A total of 525 individuals from across the range of Himalopsyche (Himalayas, Hengduan Shan, Tian Shan, South East Asia, Japan, and western North America) was analysed and 32 operational taxonomic units (OTUs) in our dataset delimited. Four distinct larval types of Himalopsyche are uncovered, and these are defined as the phryganea type, japonica type, tibetana type, and gigantea type and a comparative morphological characterisation of the larval types is presented. The larval types differ in a number of traits, most prominently in their gill configuration, as well as in other features such as setal configuration of the pronotum and presence/absence of accessory hooks of the anal prolegs

Gill Structure Linked to Ecological and Species Diversification in a Clade of Caddisflies

Streams represent a special case of directional environmental gradients where ecological opportunity for diversification may be associated with upstream and downstream dispersal into habitats that differ in selective pressures. Temperature, current velocity and variability, sediment erosion dynamics and oxygen saturation are key environmental parameters that change in predictable ways from springs to river mouth. Many aquatic insects occupy specific longitudinal regions along these gradients, indicating a high degree of adaptation to these specific environmental conditions. In caddisflies, the evolution of tracheal gills in larval and pupal stages may be a major driver in oxygen uptake efficiency and ecological diversification. Here we study the evolution of larval gill structure in the Rhyacophila vulgaris species group using phylogenomic methods. Based on anchored hybrid enrichment, we sequenced 97 kbp of data representing 159 independent nuclear protein coding gene regions to infer the phylogeny of the R. vulgaris species group, whose species exhibit both high diversity of gill types and varied longitudinal preferences. We find that the different gill types evolved independently as derived characters in the genus and that gill structure is linked to the longitudinal habitat preference, thereby serving as a possible ecological key innovation in the R. vulgaris group

Non-Standard Errors

In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across researchers adds uncertainty: Non-standard errors (NSEs). We study NSEs by letting 164 teams test the same hypotheses on the same data. NSEs turn out to be sizable, but smaller for better reproducible or higher rated research. Adding peer-review stages reduces NSEs. We further find that this type of uncertainty is underestimated by participants

The Persistence of the Criminal Justice Gender Gap: Evidence from 200 Years of Judicial Decisions

We document persistent gender gaps favoring females in jury convictions and judge sentences in nearly 200 years of London trials, which are unexplained by case characteristics. We find that three sharp changes in punishment severity locally affected the size and nature of the gaps, but were generally not strong enough to offset their persistence. These local effects suggest a mechanism of taste-based discrimination (paternalism) where the all-male judiciary protected females from the harshest available punishment.JEL-code: J16, K14, K40, N3

The Impact of the First Professional Police Forces on Crime

This paper evaluates how the introduction of professional police forces affected crime using two natural experiments in history: the 1829 formation of the London Metropolitan Police (the first police force ever tasked with deterring crime) and the 1839 to 1856 county roll-out of forces in England and Wales. The London Met analysis relies on two complementary data sources. The first, trial data with geocoded crime locations, allows for a difference-indifferences estimation that finds a significant and persistent reduction in robbery but not homicide or burglary. A pre-post analysis of the second source, daily police reports of both cleared and uncleared crime incidents, finds a significant reduction in all violent crimes but offsetting changes in uncleared (decrease) and cleared (increase) property crimes. These (local) reductions in crime are not just due to crime displacement but represent true decreases in overall crime. Difference-in-difference analyses of the county roll-out find that only sufficiently large forces, measured by the population to force ratio, significantly reduced crime. The results are robust to controlling for spill-over effects of neighboring forces.JEL-codes: K42, N93, H0

Being provided with a safe haven : Care-dependent older persons' participation in prehospital emergency care

Participation in care is a key concept in many welfare societies and serves to guide clinical practice and adapt care to personal preferences and needs in order to promote well-being and quality of life. Previous research has shown that practicing participation in care is complex due to the concept not being clearly defined. A significant risk is, therefore, that participation in care is practiced based on the professional caregivers' own definitions, which might be inconsistent with the cared-for persons' perceptions of what participation is. Older persons can continue to live in their own homes with the support of municipal home care services that meet everyday care needs. Care-dependent older persons are known to have increased emergency care needs, which in Sweden require inter-organizational and inter-professional collaboration involving a care transfer between welfare levels. This thesis aimed to deepen the understanding of care-dependent older persons' participation in prehospital emergency care from lifeworld and welfare perspectives. The inductive design was based on a lifeworld approach and included triangulation of the phenomenon of participation in care using descriptive, interpretative, and comparative methods. From the perspective of care-dependent older persons, participation in prehospital emergency care means a forced transfer of life responsibility to professional caregivers when being existentially unsafe and incapacitated due to acute illness. Through authorized representation, the professional caregivers act for the older person, with the power to bring about change and create opportunities for existence. Care-dependent older persons' participation in prehospital emergency care involves a deepened dependence that necessitates coexistence and being provided with a 'safe haven' through the entire emergency care chain. A 'safe haven' can be understood as an unconditional, calm, and sheltered interpersonal space for emotional rest that is provided to the older person during an existentially challenging situation. From the perspective of care-dependent older persons, the emergency care chain transcends organizational boundaries and includes mobile safety alarm services and emergency department attendance. The involved professionals must be supported in practicing participation in care based on a comprehensive understanding of the concept, and emergency care options must be aligned with the care-dependent older persons' need for coordinated and continuous care. Collaborative challenges related to unstructured collaboration and professional hierarchy need to be addressed to support well-functioning collaboration in situations involving acutely ill older persons. The involved organizations need to recognize care-dependent older persons'  deepened dependence when acutely ill, as well as their extended view of the prehospital emergency care chain
