The paper deals with the velocity fields in the neighbourhood of the breakers and the correlation between the wave asymmetry and the velocity asymmetry. The velocity measurements were made on two beach slopes 1 9 and 1.18. Earlier work (3) showed that the two slopes produced different breaker types; the slope of 1:9 produced plunging breakers and the slope of 1 18 spilling breakers. The velocities (velocity - tune history) of the water particles were measured at a height of 5mm above the bed using the hydrogen bubble method combined with cine photography. Two types of horizontal velocity asymmetry were defined and investigated, namely (1) horizontal velocity (Magnitude) asymmetry and (2) horizontal velocity (time) asymmetry. It was found that there are both qualitative and quantitative correlation between the asymmetry of the wave, and the asymmetry of the resulting velocity field. As a result of the correlation two alternative expressions are given for the horizontal velocity (magnitude) asymmetry.

This study is an investigation of the expression of negation in the history of Greek, through quantitative data from representative texts from three major stages of vernacular Greek (Attic Greek, Koine, Late Medieval Greek), and qualitative data from Homeric Greek until Standard Modern. The contrast between two complementary negators, NEG1 and NEG2, is explained in terms of sensitivity of NEG2 μη‎ to nonveridicality: NEG2 is a polarity item in all stages of the Greek language, an item licensed by nonveridicality. The asymmetry in the diachronic development of the Greek negator system (the replacement of NEG1 and the preservation of NEG2) is explained with reference to the particulars of the uses of NEG2, specifically the inertial forces drawn by the nonnegative uses of NEG2, which being nonnegative did not experience the renewal pressures predicted by the Jespersen’s Cycle. These are its complementizer uses: (i) as a question particle, and (ii) in introducing verbs of fear complements. A viewpoint for Jespersen’s Cycle is proposed that abstracts away from the morphosyntactic and phonological particulars of the phenomenon and explicitly places its regularities in the semantics, accommodating not only for Greek, but for numerous other languages that deviate in different ways from the traditional description of Jespersen’s Cycle. The developments observed in the history of the Greek negator system agree with current generative theories of syntactic change, regarding the notions of up-the-tree movement.

Unequal Opportunities

This article examines the precarity of labor for women working in US broadcast television during the long 1970s, focusing on interventions by government agencies, trade unions, and individual writers and producers, with a particular focus on the Writers Guild of America (WGA) 1974 Women's Committee Report, the first major statistical survey to track the representation of women as creatives within American television. This article puts qualitative and quantitative data in direct conversation: where one captures the nuances of personal experience and the other highlights the extent of inequality, together they help fill gaps in understanding the long history of struggles for equity in media production.

The Impact

Social scientists have often had difficulty evaluating the impact of probation services, partly because expectations and political circumstances change and partly because appropriate methodologies have been slow to develop. This chapter outlines the history of evaluative research on probation. It describes the limitations of early probation research which led to erroneous conclusions that ‘nothing works’, and goes on to show how more recent research has been based on a fuller understanding of practitioner inputs through research on programmes, skills and implementation. This is starting to lead to a better understanding of which practices are effective (‘What Works’). The chapter advocates a mixed qualitative and quantitative methodology for evaluative research which combines understanding, measurement and comparison. Finally, it points to some risks to evidence-based policy which arise from current populism and post-truth politics.

Media Manipulation

AbstractThis article shows how one can read political history from evidence on corporate corruption. The study exploits newly discovered archival material from Banque de Paris et des Pays-Bas, a politically connected investment bank. We contribute to current research by replacing existing conjectures with precise qualitative and quantitative evidence. After reviewing previous works and providing a sketch of information repression and media control in France during the interwar period, we argue that the study of patterns of ‘informational criminality’ provides an original entry to the writing of political history and the history of information.

Preeclampsia and eclampsia are the second direct cause of maternal death worldwide, estimated to complicate 2-8% of all pregnancies, the global prevalence of preeclampsia is around 4.6%. The purpose of this scoping review is to provide an overview of studies related to antenatal support, access and services to mothers with a history of preeclampsia in pregnancy. The authors identify studies that explain preeclampsia in pregnancy from several databases namely PubMed, ProQuest, EBSCO and Springer Link. Searches are limited to studies published in English and present data for the 2009-2019 period. The identified study was reviewed using PRISMA Flowchart. Studies with qualitative and quantitative designs that explore the experiences of pregnant women regarding antenatal support, access and services were selected for review, while studies that were not experience related to antenatal support, access and services to mothers with a history of preeclampsia in pregnancy were excluded. A total of twelve articles were reviewed which obtained three sub-themes of support, namely the support of husband, family and health workers, from the theme of access obtained three sub-themes namely information search, modification programs and the availability of health workers. From the theme of antenatal care, four sub-themes are found, namely unsustainable care, lack of information, screening and feeling empowered. Pregnant women with preeclampsia need support from a partner or family and health workers. Information and screening need to be improved in antenatal care.

Whereas most educators have a good grasp on the history of simulation in healthcare, the current state and types of modalities related to simulation in healthcare education, and the future direction of healthcare simulation, many educators do not have an in-depth understanding of the metrics available to assess the use of simulation. The purpose of this literature synthesis is to build a repository of the metrics being used to evaluate nursing and healthcare provider simulation. Additionally, the level of fidelity and desired learning domains that the matrices purport to evaluate is examined. A secondary purpose of the literature synthesis is to determine if a suitable metric is available that can be used universally to evaluate nursing and healthcare related simulations. Finally, conceptual frameworks suitable for serving as the bases of instrument development related to nursing and health care simulation are explored. Primary studies, meta-analyses, and systematic reviews that discussed or evaluated metrics used to measure outcomes of simulation were analyzed. Recent articles, published within the last five years, which discussed the evaluation of nursing and or healthcare simulation, were eligible for inclusion. Additionally, descriptive, inferential, qualitative, and quantitative studies were eligible for inclusion.

In this paper we review the history of the search for and study of the motions of nearby galaxies with respect to the Hubble Flow. The current status of the field is that (1) convincing infall has been detected into dense clusters, especially the Virgo cluster, (2) the microwave background direction is moderately well aligned with the measured flow nearby but not apparently on larger scales, and (3) there is good but not perfect consistency between the nearby density fields and velocity fields. Particular problems exist in the different Ω's required to fit the density field derived from optically selected and IRAS (60μ) selected galaxy samples.
