    Regulating Business Innovation as Policy Disruption: From the Model T to Airbnb

    Get PDF
    Many scholars have invoked the term disruptive innovation when addressing the platform (sharing) economy, with sweeping claims about the dramatic changes this development promises for law, regulation, and the economy. The challenges raised by the platform economy are surely important, but we argue that recent scholarship focusing on the immediacy and novelty of the platform economy has been ahistorical, and has therefore missed the bigger picture about how to regulate it. History is full of technological and management advances that fundamentally disrupted business models for a brief period of time. When business innovation upends a preexisting business model in a regulated industry, the result can be a disjunction between the structure of the regulatory system governing incumbent firms and the firms disrupting the industry: a policy disruption. Policy disruption can result from conscious choices by entrepreneurs to exploit legal loopholes or to challenge regulatory protections for incumbents. But it can just as easily result from gaps in a regulatory regime or fundamentally new business models that solve problems legal regimes have been designed to address. This Article is the first to offer a comprehensive analytical framework of how business innovation can create policy disruption and how regulators should respond. We develop a three-step process that should guide regulators in responding to policy disruptions, suggesting that, as a default, regulators should strive to be neutral as between incumbents and innovators. We conclude by offering specific policy instruments that regulators can use to draft laws more neutrally to avoid or limit such policy disruptions in the future

    The Effect of Static Stretching on Proprioception, Pennation Angle, and Muscle Power Production

    With widespread use of pre-exercise stretching methods across sport and exercise, recent studies have questioned the effectiveness of such methods (Kay & Blazevich 2012; Cramer et al., 2005; Curry, Chengkalath, Crouch, Romance, & Manns, 2009). The purpose of this study was to examine how the relationship between pennation angle, proprioception, and muscle power are influenced by a static stretching protocol. Participants (n = 17) from a southeastern university in the United States consented to participate and were divided into an experimental group (n = 12) and control group (n = 5). The experimental group engaged in static stretched by placing the right foot on an incline board and maximally dorsiflexing the ankle joint while keeping the bottom of their foot flush with the board’s surface and the knee fully extended. The control group remained seated for the same amount of time and did not engage in stretching. Both groups were measured for vertical jump using the Vertec force plate, electrical activity of the gastrocnemius via the Terason ultrasound machine, and proprioception of the ankle joint via the Biodex 2 dynamometer pre- and post- stretching and control protocols. Results indicated that static stretching resulted in a decrease in muscle power without change of proprioception or electrical-mechanical delay while accompanied by an increase in pennation angle. The increase in pennation angle may the reason why static stretch resulted in a reduction in muscle power. The results are discussed in regard to previous research and future practical application

    Relating imperatives to action

    Get PDF
    The aim of this chapter is to provide an analysis of the use of logically complex imperatives, in particular, imperatives of the form Do A1 or A2 and Do A, if B. We argue for an analysis of imperatives in terms of classical logic which takes into account the influence of background information on imperatives. We show that by doing so one can avoid some counter-intuitive results which have been associated with analyses of imperatives in terms of classical logic. In particular, I address Hamblin's observations concerning rule-like imperatives and Ross' Paradox. The analysis is carried out within an agent-based logical framework. This analysis explicates what it means for an agent to have a successful policy for action with respect to satisfying his or her commitments, where some of these commitments have been introduced as a result of imperative language use

    Global change impacts on bird biodiversity in South Asia: potential effects of future land-use and climate change on avian species richness in Pakistan

    Get PDF
    Evaluating the impact of future changes in land-use and climate on species communities, especially species richness, is one of the most important challenges of current research in ecology and conservation. The impact of environmental changes on species richness depends on its sensitivity (i.e., how strongly a given level of change influences the ecological community) and its exposure (i.e., the amount of change that occurs). To examine the sensitivity, exposure, and potential impact of future environmental conditions on bird communities, we compiled data on bird species richness for Pakistan—a neglected region in macro- or country-scale studies. Since bird species richness strongly varies across seasons due to the seasonal occurrence of migratory species in winter, we compared both wintering (migratory plus resident species) and breeding (resident species only) bird richness. We found breeding and wintering species richness to be sensitive to temperature, precipitation and rainfed cropland by being positively related to these factors. Exposure varied regionally, with projected temperature changes being most profound in northern regions while the strongest projected precipitation changes occurred in central and southern regions. The projected impact of future environmental change were highly heterogeneous across the country and differed between the wintering and breeding communities. Overall, the most negatively impacted region was projected to be the Khyber Pakhtunkha province in the North of Pakistan, due to reductions in precipitation and rainfed cropland, resulting in a projected negative impact, especially on wintering species richness. By highlighting the regional and seasonal bird communities most at risk, our findings provide useful information for policy makers to help devise new policies for mitigating negative impacts of future environmental changes on birds within Pakistan

    Promoter keyholes enable specific and persistent multi-gene expression programs in primary T cells without genome modification

    Get PDF
    Non-invasive epigenome editing is a promising strategy for engineering gene expression programs, yet potency, specificity, and persistence remain challenging. Here we show that effective epigenome editing is gated at single-base precision via 'keyhole' sites in endogenous regulatory DNA. Synthetic repressors targeting promoter keyholes can ablate gene expression in up to 99% of primary cells with single-gene specificity and can seamlessly repress multiple genes in combination. Transient exposure of primary T cells to keyhole repressors confers mitotically heritable silencing that persists to the limit of primary cultures in vitro and for at least 4 weeks in vivo, enabling manufacturing of cell products with enhanced therapeutic efficacy. DNA recognition and effector domains can be encoded as separate proteins that reassemble at keyhole sites and function with the same efficiency as single chain effectors, enabling gated control and rapid screening for novel functional domains that modulate endogenous gene expression patterns. Our results provide a powerful and exponentially flexible system for programming gene expression and therapeutic cell products

    Developing effective practice learning for tomorrow's social workers

    Get PDF
    This paper considers some of the changes in social work education in the UK, particularly focusing on practice learning in England. The changes and developments are briefly identified and examined in the context of what we know about practice learning. The paper presents some findings from a small scale qualitative study of key stakeholders involved in practice learning and education in social work and their perceptions of these anticipated changes, which are revisited at implementation. The implications for practice learning are discussed

    Tapes, transcripts and trials:The routine contamination of police interview evidence

    Get PDF
    This article addresses a serious, but currently unacknowledged, problem of evidential consistency regarding police-suspect interview evidence. It sheds light on flaws in current criminal procedure through the lens of linguistics, focusing on key stages of currently accepted practice which fly in the face of what linguists have long known about language. It demonstrates that, in stark contrast to the strict principles of preservation applied to physical evidence, interview data go through significant transformation between their creation in the interview room and their presentation in the courtroom, especially through changes in format between written and spoken text. It argues that, despite the safeguards provided by PACE 1984, there is nonetheless a level of routine distortion and contamination unintentionally built in to the current system of presenting police interviews as evidence in England & Wales

    Holistic corpus-based dialectology

    Get PDF
    This paper is concerned with sketching future directions for corpus-based dialectology. We advocate a holistic approach to the study of geographically conditioned linguistic variability, and we present a suitable methodology, 'corpusbased dialectometry', in exactly this spirit. Specifically, we argue that in order to live up to the potential of the corpus-based method, practitioners need to (i) abandon their exclusive focus on individual linguistic features in favor of the study of feature aggregates, (ii) draw on computationally advanced multivariate analysis techniques (such as multidimensional scaling, cluster analysis, and principal component analysis), and (iii) aid interpretation of empirical results by marshalling state-of-the-art data visualization techniques. To exemplify this line of analysis, we present a case study which explores joint frequency variability of 57 morphosyntax features in 34 dialects all over Great Britain

    Punk is just a state of mind: Exploring what punk means to older punk women

    Get PDF
    What does punk mean to older punk women? And how are such understandings interwoven with experiences of ageing and gender? The complexity in defining punk has been noted and it has been suggested that this complexity in part results from punk’s dislike of being labelled/categorised. Drawing upon interviews with 22 self-identifying older punk women, this article considers how they conceived punk as ‘a state of mind’, exploring the four shared punk values seen to comprise this: DIY, subversion, political consciousness and community. An unpacking of these values in terms of what they might ‘look like’ and how they are put into action by the women highlights the considerable roles ageing and gender play
