The Benefits of Being Economics Professor A (and not Z)
No full textAlphabetic name ordering on multi-authored academic papers, which is the convention in the economics discipline and various other disciplines, is to the advantage of people whose last name initials are placed early in the alphabet. As it turns out, Professor A, who has been a first author more often than Professor Z, will have published more articles and experienced afaster growth rate over the course of her career as a result of reputation and visibility. Moreover, authors know that name ordering matters and indeed take ordering seriously: Several characteristics of an author group composition determine the decision to deviate from the default alphabetic name order to a significant extent.performance measurement, incentives, economists, name ordering

Participation as a tool for interactional work on Twitter: A sociolinguistic approach to social media 'engagement'
No full textThis work approaches the concept of social media engagement through a lens of participation theory. Following the work of Goffman (1981) and others, this dissertation uses the concepts of the participation framework and the participant role to explore engagement as a function of participation in interaction. The purposes of this dissertation are three-fold: to model participant roles as they are built in interaction on Twitter, to discover the ways in which participation is established through the linguistic choices enacted by participants, and to demonstrate the role of the medium as an important factor influencing possibilities for participation. Using discourse analysis as a methodology, tweets from accounts associated with National Hockey League (NHL) organizations are analyzed for the linguistic resources that are used to reference interactional roles traditionally understood as “speaker” and “hearer”. In turn, the linguistic and discursive resources deployed in team tweets are used to reveal these speaker and hearer roles as more detailed and complex production and reception frameworks. The modal affordances of Twitter are also investigated as to their role in influencing the building of participation frameworks through talk, including unique linguistic forms that are available to Twitter users and possibilities for hiding or revealing participants through the Twitter screen.
The findings of this investigation reveal three primary models for production frameworks for NHL accounts: an Impersonal Model that eschews identification of the parties in production roles, an Interpersonal Model that highlights the individuals involved in the interaction, and a Team Model that obscures the individual to focus on the team or organization as a primary participant. Additionally, a framework for understanding recipient audiences on Twitter is proposed, incorporating both actual and intended audiences. Consistent patterns in the language choices used to construct participatory identities for production and reception roles are demonstrated, highlighting the value of using linguistic data as a resource for investigations of participation. Finally, Twitter’s modal affordances are shown to be an integral part of the ways that users enact participatory concepts, such as co-presence and address, revealing the importance of considering the role of the medium in participation studies
The case of Mobility as a Service: A critical reflection on challenges for urban transport and mobility governance
No full textThis chapter provides a reflective critique of Mobility as a Service (MaaS), an emerging development seeking a role within the Smart Mobility paradigm. We assess a range of its future implications for urban policymakers in terms of governance and sustainability (i.e., social and environmental impacts). We begin by describing the origins of the MaaS concept, along with the features of precursor technologies and current early examples. We then reflect on the marketing of MaaS and use it to consider how we might anticipate some potentially less desirable aspects of the promoted business models. Finally, we discuss the implications for governance.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Spatial Planning and StrategyTransport and Plannin
Molinist Gunslingers Redux: A Friendly Response to Greg Welty
No full textPhilosopher Greg Welty contributed a chapter entitled ‘Molinist Gunslingers: God and the Authorship of Sin’, to a book devoted to answering the charge that Calvinism makes God the author of sin (Calvinism and the Problem of Evil). Welty argues that Molinism has the same problems as Calvinism concerning God’s relationship to sin, regardless of what view of human freedom Molinism may affirm. The Molinist believes that God generally uses his knowledge of the possible choices of libertarianly free creatures in order to accomplish his will. (This knowledge is typically categorized as residing within God’s middle knowledge.) But affirming libertarian freedom for humans, he argues, does not help in dealing with the question of God’s relationship to evil. Therefore, Molinism is no better than Calvinism, at least concerning this issue. In response to Welty, (1) I agree with him that Molinism does not have a moral advantage over what he calls ‘mysterian, apophatic’ Calvinism, but Molinists don’t claim that it does, and (2) I argue that, contra Welty, Molinism indeed does have a moral advantage over the Calvinist versions that do employ causal determinism. Welty does not take ‘intentions’ into consideration in his argument, and this is a serious flaw. In the libertarian model of Molinism, intent originates in the doer of evil. However, in the compatibilist model of causal determinism, ultimately God implants intent. Thus, adherents of causal determinism have difficulty not laying responsibility at the feet of God
Contemporary Surgical Management of Colorectal Liver Metastases
No full textColorectal cancer is the third most common cancer in the United States and the second most common cause of cancer-related death. Approximately 20–30% of patients will develop hepatic metastasis in the form of synchronous or metachronous disease. The treatment of colorectal liver metastasis (CRLM) has evolved into a multidisciplinary approach, with chemotherapy and a variety of locoregional treatments, such as ablation and portal vein embolization, playing a crucial role. However, resection remains a core tenet of management, serving as the gold standard for a curative-intent therapy. As such, the input of a dedicated hepatobiliary surgeon is paramount for appropriate patient selection and choice of surgical approach, as significant advances in the field have made management decisions extremely nuanced and complex. We herein aim to review the contemporary surgical management of colorectal liver metastasis with respect to both perioperative and operative considerations
Hearing Faces and Seeing Voices: The Integration and Interaction of Face and Voice Processing
No full textCognitive understanding of voice recognition has borrowed much from the area of face processing, both in terms of the theoretical framework within which results are interpreted, and the methodology used to assess performance. A considerable body of research now exists to suggest that voice recognition may proceed in parallel with face recognition, and that the two pathways may combine to inform person recognition. However, rather than being independent or equivalent, these parallel pathways appear to interact to reveal interesting interference effects. The present paper reviews a series of studies that focus on a considerable and growing literature. The vulnerability of voice processing will be explored relative to face processing, and the interaction of these two pathways will be examined with reference to broader theoretical frameworks for person recognition
Issues in the Issuance of Enhanced Annuities
No full textTwo forces are about to create a growing market for Individual Annuities in the U. S. and Canada. First, the Post War Baby Boom (born 1946 to 1964) is inexorably moving into retirement. Second, there is a strong move away from Employer-sponsored Defined Benefit pension plans to Defined Contribution pension plans. This trend could even extend (in the U.S.) into the provision of Social Security benefits. Under these arrangements, participants must find a way to mitigate their “longevity” risk (and the investment risk, although this is not the topic of this paper). The most obvious answer is to buy a life annuity. However, at this time in the U. S. and Canada, persons who voluntarily apply to buy a life annuity are generally assumed to be in extremely good health and annuity rates are determined using very low mortality assumptions (high life expectancy assumptions). While there is a growing market in “Enhanced/Impaired Annuities”, especially in the U.K., the present pricing structure for annuities in the U. S. and Canada means that a large proportion of the population cannot get a “fair value” annuity given their less-than-preferred health profile. This paper looks at reasons for this market reality in the U. S. and Canada. It also reviews the underwriting and marketing of life annuities in the United Kingdom where “enhanced” life annuities are available for a broader cross-section of the marketplace.Individual Annuities, Defined Benefit Pension Plan, Defined Contribution Pension Plan, Retirement Income Security, Life Expectancy, Impaired Mortality
Evaluation of quarter-based selective dry cow therapy using Petrifilm on-farm milk culture: A randomized controlled trial
No full textThe objective of this randomized controlled trial was
to assess the efficacy of an on-farm culture system using Petrifilm (3M, London, ON, Canada) for targeted
treatment decisions at the quarter level at dry-off and
its effects on dry period intramammary infections (IMI)
and udder health and milk production in the subsequent lactation. A total of 568 cows (2,247 quarters)
from 9 dairy herds with bulk tank somatic cell count
<250,000 cells/mL in Québec, Canada, were systematically enrolled and randomly allocated to 4 groups: 2
quarter-based selective (QSDCT) groups, using results
of quarter-milk culture on Petrifilm, and 2 blanket dry
cow therapy (BDCT) groups. The 2 QSDCT groups
consisted of (1) antimicrobial to infected quarters and
internal teat sealant (ITS) to healthy quarters (QSDCT/ITS); and (2) antimicrobial and ITS to infected
quarters and ITS to healthy quarters (QSDCT+ITS/
ITS). The 2 BDCT groups were (1) antimicrobial alone
to all quarters (BDCT); and (2) antimicrobial and ITS
to all quarters (BDCT+ITS). Quarter milk samples
were collected at dry-off and after calving for routine
bacteriological culture at the laboratory to monitor
IMI; data on milk production, somatic cell count, and
clinical mastitis recorded up to 120 d in milk were retrieved from health and DHI records. The probability
of avoiding antimicrobial treatment in QSDCT groups
was estimated at 48.3% (95% confidence interval: 35.7,
60.9). There was no significant difference between the
4 treatment groups regarding acquisition of new IMI
(15.9, 13.2, 15.8, and 15.1% probability for BDCT,
BDCT+ITS, QSDCT/ITS, and QSDCT+ITS/ITS,
respectively) or persistence of existing IMI (3.2, 2.1,
3.4, and 2.7% probability, respectively) over the dry
period. In the subsequent lactation, there was no difference between groups regarding incidence of clinical
mastitis (2.4, 3.7, 2.9, and 1.7% respectively for BDCT,
BDCT+ITS, QSDCT/ITS, and QSDCT+ITS/ITS),
mean milk somatic cell score (1.7, 2.0, 2.0, and 2.0 respectively), or mean daily milk production (43.8, 44.2,
43.2, and 42.6 kg/d, respectively) during the first 120
d in milk. In conclusion, QSDCT using the Petrifilm
on-farm culture system to detect infected quarters at
dry-off is an interesting option to decrease antibiotic
use without any negative effects on udder health or
milk production in the first 120 d of the subsequent
lactation compared with BDCT.

Coping among public safety personnel: a systematic review and meta-analysis
No full textPublic safety personnel (PSP) are routinely exposed to potentially psychologically traumatic events (PPTEs) that, in turn, can result in posttraumatic stress injuries (PTSI), including burnout and increased symptoms of depression and anxiety. However, the longitudinal impact of PPTEs on PSP coping remains unclear. Coping can be operationalized as various strategies (i.e., behaviours, skills, thought and emotion regulation) for dealing with stressors, which are broadly categorized as either approach (adaptive, positive, social support) or avoidant coping strategies (maladaptive withdrawal, avoidance, substance use). This systematic review and meta‐analysis aims to evaluate longitudinal coping outcomes among PSP. Thirteen eligible repeated‐measures studies explicitly evaluated coping in 1854 police officers, firefighters, and rescue and recovery workers. Study designs included randomized‐control trials, within‐subject interventions and observational studies. Effect sizes (Cohen's d) at follow‐up were described in 11 studies. Separate metaanalyses reveal small (d < 0.2) but non‐significant improvements in approach and avoidant coping. Studies were of moderate quality and low risk of publication bias. Heterogeneity in outcome measures, follow‐up durations, and study types precluded subgroup analyses. The current findings can inform the development and evaluation of organizational training programs that effectively promote sustained adaptive coping for PSP and mitigate PTSIs.Peer reviewedcoping; meta-analysis; occupational health; organizational stress interventions/prevention; posttraumatic stress; public safety personnel; traumatic stres
