Pathos and patter in real estate parlance

This paper presents the first systematic analysis of estate agent language and employs Aristotle’s ponderings on the art of persuasion as a means of classifying the peculiar parlance of property peddlers. “Des. Res.”, “rarely available”, “viewing essential” – these are all part of the peculiar parlance of housing advertisements. The question is whether the selling agent’s penchant for rhetoric is uniform across a single urban system or whether there are variations, even within a relatively limited geographical area. We are also interested in how the use of superlatives varies over the market cycle. For example, are estate agents more inclined to use hyperbole when the market is buoyant or when it is flat? This paper attempts to answer these questions by applying textual analysis to a unique dataset of 49,926 records of real estate transactions in the West of Scotland over the period 1999 to 2006. Our analysis has implications for our understanding of the agency behaviour of housing market professionals and endeavours to open up a new avenue of research into the market-impact of rhetoric in the language of selling

Optimal cellular mobility for synchronization arising from the gradual recovery of intercellular interactions

Cell movement and intercellular signaling occur simultaneously during the development of tissues, but little is known about how movement affects signaling. Previous theoretical studies have shown that faster moving cells favor synchronization across a population of locally coupled genetic oscillators. An important assumption in these studies is that cells can immediately interact with their new neighbors after arriving at a new location. However, intercellular interactions in cellular systems may need some time to become fully established. How movement affects synchronization in this situation has not been examined. Here we develop a coupled phase oscillator model in which we consider cell movement and the gradual recovery of intercellular coupling experienced by a cell after movement, characterized by a moving rate and a coupling recovery rate respectively. We find (1) an optimal moving rate for synchronization, and (2) a critical moving rate above which achieving synchronization is not possible. These results indicate that the extent to which movement enhances synchrony is limited by a gradual recovery of coupling. These findings suggest that the ratio of time scales of movement and signaling recovery is critical for information transfer between moving cells.Comment: 18 single column pages + 1 table + 5 figures + Supporting Informatio

Nonlinearity arising from noncooperative transcription factor binding enhances negative feedback and promotes genetic oscillations

We study the effects of multiple binding sites in the promoter of a genetic oscillator. We evaluate the regulatory function of a promoter with multiple binding sites in the absence of cooperative binding, and consider different hypotheses for how the number of bound repressors affects transcription rate. Effective Hill exponents of the resulting regulatory functions reveal an increase in the nonlinearity of the feedback with the number of binding sites. We identify optimal configurations that maximize the nonlinearity of the feedback. We use a generic model of a biochemical oscillator to show that this increased nonlinearity is reflected in enhanced oscillations, with larger amplitudes over wider oscillatory ranges. Although the study is motivated by genetic oscillations in the zebrafish segmentation clock, our findings may reveal a general principle for gene regulation.Comment: 11 pages, 8 figure

Synchronization in the presence of distributed delays

We study systems of identical coupled oscillators introducing a distribution of delay times in the coupling. For arbitrary network topologies, we show that the frequency and stability of the fully synchronized states depend only on the mean of the delay distribution. However, synchronization dynamics is sensitive to the shape of the distribution. In the presence of coupling delays, the synchronization rate can be maximal for a specific value of the coupling strength.Comment: 6 pages, 3 figure

The Multi-Level Marketing Pandemic

Among the societal effects of the COVID-19 pandemic has been a sharp rise in the activities of multi-level marketing companies (MLMs). MLMs are business enterprises in which participants seek not only to sell products to friends, family, and social media contacts, but also to recruit them as MLM participants, with the promise of building their own business from home. False promises often pervade MLM sales pitches. Evidence shows that few participants see even a dollar of profit from their MLM work; the vast majority of recruits quickly abandon their MLM dreams and lose their investments. Yet the pitch has become all the more appealing in the course of the pandemic. Many people are desperate - unemployed and in need of immediate earnings as well as flexible, at-home work due to health concerns and family responsibilities. MLMs have been particularly appealing to the working mothers who, evidence shows, have borne the brunt of COVID-19\u27s impact on employment, childcare, and household responsibilities. Regulators have long scrutinized and fought the worst abuses of MLMs. They have sought to shut down unscrupulous MLMs that are nothing more than fraudulent pyramid schemes, and to curtail the misrepresentations and exaggerations that are all too often the stock in-trade of MLM participants. But regulators, including the Federal Trade Commission (FTC), face significant legal and practical limitations in their ability to promulgate and enforce MLM regulations. This Article proposes means of stemming the pandemic-driven expansion of unlawful MLM activities. It assesses efforts by regulators, by social media companies, and by self-regulatory organizations set up by MLMs themselves. Comprehensive, long-term success at curbing the abuses of MLMs will require more significant regulatory action than is currently permitted by law. The steps outlined here can provide some much-needed relief for consumers harmed by the unlawful MLM activities that have been fostered by the pandemic. They may also provide a blueprint for nimble regulatory responses to future crises when unscrupulous MLM promoters will, no doubt, further adapt their strategies to take advantage of the vulnerable

Understanding the introduction and use of a mobile device-supported health information system in Nigeria

Copyright @ 2014 The Authors.This paper presents an in-depth analysis of efforts to introduce a mobile health information system in Nigeria as part of a development initiative aimed at improving maternal and child health. Specifically, it examines the use of mobile devices to facilitate maternal health information accessibility and exchange among health practitioners in order to reducing maternal, newborn and child mortality. Further, it also looks at the challenges raised while introducing mobile devices into work practices in the healthcare sector. The study adopts a case study approach, relying on semi-structured interviews and document analysis as its main methods for collecting data. The specific case examined is a mobile phone-based information system introduced to support a national government effort in Nigeria, known as the midwives service scheme. The findings of this study show that this integrated approach of using mobile phones to support (health) information systems has vast potential; for instance increasing the timeliness of (health) data available to stakeholders for monitoring and planning purposes. However, we also find that over time, attaining the potential of development efforts such as this remains difficult as initiatives involving the use of mobile devices is not just about getting the technical aspect right. It is equally dependent on deep seated social-cultural influences such as poor political and financial commitment. These two mutually reinforcing influences have been identified in this study as significant impediments to efforts of this kind. Therefore, this paper argues for, first a strong political commitment across all levels of government whereby their words are backed with action. Second it is important that the government maintains financial integrity by releasing the funds budgeted to support the smooth running of these efforts, for such initiatives to thrive and ultimately contribute to development
