title: Neutral-current Drell-Yan measurements at the ATLAS experiment and their phenomenological interpretation
Creators: name: Gonzalez Lopez, Ricardo
Publisher: name: University of Liverpool Repository
Year: 2023

description: The neutral-current Drell-Yan production is a process for which precise predictions are currently available, offering a benchmark upon which these state-of-the-art predictions can be tested, both as a way to improve our understanding of Standard Model physics and explore theories that expand on the foundations it establishes. This thesis provides an overview of two analyses focusing on the Drell-Yan production using LHC Run 2 pp collision data collected by the ATLAS experiment during the years 2015 to 2018 at √s=13 TeV. First, a measurement of the single- and double-differential production cross-section in an invariant mass region of 116 to 5000 GeV is presented, using Z/γ* decays into lepton pairs in the electron and muon channels. The measurement is performed as a function of invariant mass, absolute rapidity of the lepton pair and their angle separation in the Z-boson rest frame. The results obtained are used to perform for the first time tests on lepton flavour universality (LFU) as well as set limits on Effective Field Theory (EFT) coefficients that modify the Drell-Yan production cross-section. Second, a novel search for Lorentz-invariance violating (LIV) signatures using Z-decays into electron and muon pairs is presented. Using the methodology for a luminosity measurement based on the counting of Z-bosons detected, the time-dependence of the Drell-Yan production can be monitored. While the Standard Model predicts no time-dependence on this process, deviations from this behaviour can be interpreted as the effects of LIV-inducing operators in the Standard Model Extension EFT. The results presented in this thesis include an overview of the Z-counting measurement methodology transfer to a flexible analysis framework, as well as the development of new time-dependent simulation tools to estimate expected sensitivities.

description: In both light optics and electron optics, the amplitude of a wave scattered by an object is an observable that is usually recorded in the form of an intensity distribution in a real space image or a diffraction image. In contrast, retrieval of the phase of a scattered wave is a well-known challenge, which is usually approached by interferometric or numerical methods. In electron microscopy, as a result of constraints in the lens setup, it is particularly difficult to retrieve the phase of a diffraction image. Here, we use a defocused beam generated by a nanofabricated hologram to form a reference wave that can be interfered with a diffracted beam. This setup provides an extended interference region with the sample wavefunction in the Fraunhofer plane. As a case study, we retrieve the phase of an electron vortex beam. Beyond this specific example, the approach can be used to retrieve the wavefronts of diffracted beams from a wide range of samples.

description: For a nonempty polyhedral set $P\subset \mathbb R^d$, let $\mathcal F(P)$ denote the set of faces of $P$, and let $N(P,F)$ be the normal cone of $P$ at the nonempty face $F\in\mathcal F(P)$. We prove that the function $\sum_{F\in\mathcal F(P)}(-1)^{\text{dim} F} 1_{F-N(P,F)}$ equals $1$ if $P$ is bounded, or $0$ if $P$ is unbounded and line-free. Previously, this formula was known to hold everywhere outside some exceptional set of Lebesgue measure $0$ or for polyhedral cones. The case of a not necessarily line-free polyhedral set is also covered by our general theorem.

description: We report the electronic transport properties of a new photo-addressable molecular switch. The switching process relies on a new concept based on linear π-conjugated dynamic systems, in which the geometry and hence the electronic properties of an oligothiophene chain can be reversibly modified by the photochemical trans-cis isomerization of an azobenzene unit fixed in a lateral loop. Electron transport measurements through self-assembled monolayers on gold, contacted with eGaIn top contact, show switching with a conductance ratio up to 1E3. Ab initio calculations have been used to identify the most energetically stable conformations of the molecular switch, the corresponding calculated conductances qualitatively explain the trend observed in the photo-switching experiments.

This paper provides the background leading up to this need, a brief overview of the intention behind uncertainty values, and finally a revised version of MBES uncertainty requirements to support current and future products.
Overseas-Trained South Asian Doctors and the Development of Geriatric Medicine, 1955-2000
Creators: name: Bornat, J.
Publisher: name: UK Data Service
Year: 2013

description: This is a qualitative data collection. Migrant doctors have provided a significant contribution to the National Health Service workforce over the last 60 years yet their presence has been largely un-documented and their achievements unrecognised. Making good this deficit, researchers at the Open University carried out 60 oral history interviews with retired and serving overseas-trained doctors from South Asian countries about their experiences of working as geriatricians in the UK NHS from 1948 to the present day. This ESRC-funded project also links with an earlier project, carried out by Professor Margot Jefferys, 'The Pioneers of Geriatric Medicine'.

 The project team interviewed 63 retired and serving South Asian qualified doctors employed by the NHS in England and Wales. Participants were recruited through networks of overseas doctors, through the British Geriatrics Society and through snowball sampling. The interview schedule used a life history approach, starting with childhood and education, going on to medical training, migration experience, working in geriatrics and career development in the NHS. The interviewees had obtained their initial medical qualifications in India, Bangladesh, Sri Lanka, Pakistan and Burma and at the time of the interview ranged in age between 40 and 91. All except two were, or are, consultants and some also held academic posts as professors. The team also reanalysed an earlier set of interviews carried out by Margot Jefferys and colleagues in 1990-91 (deposited at the British Library) with 54 doctors who pioneered the geriatric specialty. In addition, the project made extensive use of the documents lodged in the National Archive as well as in archives relating to the medical profession.

 Further information about the project may be found on the ESRC Overseas trained South-Asian Doctors and the Development of Geriatric Medicine award webpage and on the Open University's Overseas trained South-Asian Doctors and the Development of Geriatric Medicine project website.

 The UK Data Archive data collection comprises 63 interview transcripts. Audio files are available, but due to their size, supply is by individual arrangement. Potential users of the audio data should Get in touch. The collection is also deposited at the British Library.

description: The R functions .C() and .Fortran() can be used to call compiled C/C++ and Fortran code from R. This so-called foreign function interface is convenient, since it does not require any interactions with the C API of R. However, it does not support long vectors (i.e., vectors of more than 2^31 elements). To overcome this limitation, the R package dotCall64 provides .C64(), which can be used to call compiled C/C++ and Fortran functions. It transparently supports long vectors and does the necessary castings to pass numeric R vectors to 64-bit integer arguments of the compiled code. Moreover, .C64() features a mechanism to avoid unnecessary copies of function arguments, making it efficient in terms of speed and memory usage.

Integrative phylogeny of the treehopper tribe Darnini (Hemiptera: Membracidae) reveals evolutionary convergences in mimicry-associated traits
Creators: name: Gonzalez Mozo, Laura Catalina
Publisher: name: No Publisher Supplied
Year: 2022

description: The tribe Darnini is a complex of morphologically diverse taxa which have been poorly studied. The tribe includes 86 species classified in 16 genera, distributed in South and Central America north through Mexico and into the southwest of the United States. Members of Darnini share the following synapomorphy: femora with two longitudinal rows of cucullate setae ventrally. Darnini is so poorly represented in past molecular and morphological works that its phylogenetic position within Membracidae, and the intergeneric relationships within the tribe remain unclear. Roy et al. (2007) reconstructed a phylogeny of Darnini based on 58 morphological characters, scored for 18 species from 14 genera. The aim of that study was to identify the evolution of mimicry strategies within Darnini. This work was not conclusive as stated by Roy et al. (2007) the tribe is in need of taxonomic work on several genera, and for broader taxonomic sampling to improve the evolutionary hypothesis.To test the monophyly of the tribe and achieve a better understanding of the evolutionary relationships among Darnini genera, present here are the results of a phylogenetic study based on combined molecular (CO1, 28S) and morphology data (87 morphological characters). From 74 individuals housed at several international museums and representing 10 of the 16 recognized Darnini genera. The goals of this study are: 1. Reconstruct the phylogeny of the tribe Darnini; 2 Revise and redefine the genera of the Cyphotes-group. 3 Analyze the morphology of the Cyphotes group to determine the phylogenetic history of mimetic strategies. Phylogenetic analyses were performed with the concatenated dataset (1332 base alignment inferred in MAFFT), three analyses were performed Bayesian inference, maximum likelihood, and parsimony; resulting topologies indicate the following results: (1) The subfamily Darninae is recovered as monophyletic; (2) The tribe Darnini is recovered as paraphyletic; (3) At least three different lineages related with mimetic strategies were derived, or at least reversed, more than once. At the genus level, this study provides a redefinition of 5 genera and new country records. At the species level, 14 new species are described. New morphological characters are described, and the assessment and descriptions of microstructures are provide.

description: Most agricultural lenders extend loans based on their assessment of a borrower’s ability to repay debt. Because of this, some farmers may not be able to secure as much credit as they would like for their farm businesses. A lack of credit could prevent these farmers from expanding production or could restrict investments in productivity-enhancing technologies. Off-farm income may help some farm households qualify for larger loans, which could lead to higher farm output, productivity, and profit. Using farm-level data from USDA’s Agricultural Resource Management Survey, the USDA, Economic Research Service (ERS) estimated the effect of off-farm income on farm borrowing, investment, operation size and productivity from 2007 to 2016.
Becoming British Citizens? Experiences and Opinions of Refugees Living in Scotland, 2010
Creators: name: Stewart, E.
name: Mulvey, G.
Publisher: name: UK Data Service
Year: 2013

description: This is a qualitative data collection. The overall aim of this project was to explore the experiences and opinions of refugees living in Scotland towards the UK citizenship process and becoming British citizens. In the wider context of the social cohesion agenda, the UK Government has promoted the integration of refugees. Alongside these developments, there have been several changes that have impacted upon refugees including 'English Language and Life in the UK' tests, citizenship ceremonies and the introduction of the Active Review. By drawing upon theoretical literature, analysis of secondary data and 30* in-depth interviews conducted with refugees at various stages of the citizenship process, the project explored the impact of these changes upon refugees living in Scotland. The specific research objectives were:
to examine the reasons why refugees decide to apply for British citizenship or not;

to explore the difficulties that refugees have faced in progressing towards citizenship;

to explore the views of refugees on the concepts of integration, citizenship, Britishness and Scottishness;

to determine how becoming British citizens (or not) impacts upon the daily activities of refugees, sense of self-identity and integration;

to employ research findings to inform current debate surrounding the Active Review of refugee cases and proposals for probationary citizenship.
The research identified four key reasons for refugees deciding whether to become British citizens or not. These include instrumental reasons, a search for safety and security, to develop a sense of belonging to the UK and securing legal rights in the UK. The project also explored the difficulties that refugees have faced in progressing towards citizenship including costs and the application process. Finally, the research examined the relationship between citizenship, integration and sense of belonging.

 *The UK Data Archive collection includes 28 of the 30 interviews conducted with refugees.

E-Clusters in the E-Society: the Case of the Digital Content Industry, 2005
Creators: name: Gill, R.
name: Pratt, A. C.
Publisher: name: UK Data Service
Year: 2014

description: This is a qualitative data collection. This project was concerned with the organisation and physical location of work in cutting edge e-businesses today; with the assumption that this is an appropriate 'forward position' from which to draw conclusions as to the likely state of the rest of the economy in a future, more fully developed, e-society.

 The research question was 'an examination of the forms of co-location and socio-economic interaction within and between firms in digital content industries'. The team had constructed a survey of seven clusters across 3 industries in the digital content sector. We interviewed principals of 180 firms. It succeeded in carrying out seven case studies as planned: one in Los Angeles (Venice Beach), one in London, both on the film special effects industry; three on the games industry (Scotland, North West and Yorkshire); two on digital design (Brighton and London).

 Location factors turned out to not be as straight forward as cost, but related more to industry institutions (ownership and contacting relations, and market structure), and to labour market pooling (to facilitate re-employment of freelancers), and to local knowledge networks of workers outside/across of the firms. Forms of social networking proved to be critical. However, whilst the project had expected this the research found that social networking was itself embedded in new forms of project and freelance, or precarious, working. Thus, there was a strong internal dynamic between labour processes, information and knowledge networks, and, finally the linkage to specific places. A striking finding of the research, which confirmed our hypothesis and whole thrust of the project design, was that there were significant differences within the digital content industries.

description: This is a qualitative data collection. The aims of the project were to research the intersections of sexuality, citizenship and pro-poor policy making for trafficked women upon their return to their home country of origin, Nepal. Here anti-trafficking advocacy is highly visible and together with the recent success of the pro-democracy movement and moves to create a Constituent Assembly are opening up debates on citizenship, governance, sexuality and pro-poor development. The aims of the project were:

 1. To examine the role of sexuality and citizenship in livelihood strategies, focusing particularly on the experiences of diverse groups of returnee trafficked women as new democratic processes, supported by national and transnational communities, are unfolding in Nepal

 2. To generate new gendered understandings and research approaches to the relationship between citizenship, sexuality and pro-poor development. This objective involved analysing competing discourses and policies on sexuality, trafficking and emerging models of citizenship as they intersect with pro poor development in Nepal.

 3. To examine the professionalisation of activist anti-trafficking networks and the impact of this on grassroots activists/local NGOs' ability to get sexual citizenship on transnational advocacy, donor and national pro-democracy agendas.

This qualitative data collection is part of the Rural Economy and Land Use (RELU) programme.

 This project adopted an interdisciplinary approach to the ecological, social and economic interactions at Loweswater in the English Lake District with the aim to gain a better understanding of the environmental problem of potentially toxic algal blooms formed by cyanobacteria, (blue-green algae) in Loweswater Lake. Following findings from an earlier scoping study the project achieved to: link aquatic and terrestrial ecological knowledge; to understand how economic issues for those living and working in the catchment affect resource use and management (including waste disposal), and hence Loweswater's aquatic and terrestrial ecology; to understand how institutional arrangements pertaining to agriculture, water resources, environmental protection, economic regeneration, local government, tourism and recreation shape opportunities and constraints for catchment management; to understand the role of local culture, local knowledge and understanding in shaping land and resource use and management in the catchment and to move away from a command and control regulatory style and innovate with a new bottom-up approach to addressing the catchment's problems and opportunities.

 Central to the project was the creation of a participatory, local- and stakeholder-relevant framework within which problems could be framed and re-framed, methodologies debated, and results and findings critically scrutinized by all participants. This took the form of a new experimental partnership known as the Loweswater Care Project which included relevant publics and varied forms of expertise. It followed three research objectives and research clusters (methods). These were: the creation of a new institutional mechanism the Loweswater Care Project, the creation of a knowledge-base for decision making and the transferability of the approach.

Year: 2019

description:
This qualitative data collection is part of the Rural Economy and Land Use (RELU) programme.

The project considered working on "fringe areas" in terms of its disciplinary and geographical focus, considering synergies between natural and social science approaches in rural-urban fringe (RUF) areas. The RUF, the space where countryside meets town, is amongst society's most valued and pressured places, yet in policy and decision-making it remains largely forgotten, lacking sufficient understanding and evidence for integrated management. This research looked at existing research and data, carried out primary research and co-produced material to encourage more positive, inclusive and proactive agendas for managing the RUF.

The research team consisted of academics, policy advisors and practitioners working collectively across professional, disciplinary, scalar and sectoral boundaries. Our assessment tool was a framework uniquely fusing ideas within the Ecosystem Approach (EA) and Spatial Planning (SP) to provide an improved lens within which to view the RUF. Three cross-cutting themes emerged from the fusion of SP and EA ideas; Time, Connections and Values. These concepts were unpacked within eight themed workshops (data: workshop reports) and two RUF site-based visioning exercises (data: transcripts of both visioning exercises) which formed the primary data for the project. In addition, outputs are available, including project newsletters, press releases, short professional articles, policy brief videos, and several academic journal articles are in progress or already submitted for review.

description: The properties of giant and pygmy resonances are calculated starting from chiral two-and three-nucleon interactions. The aim is to assess the predictive power of modern Hamiltonians and especially the role of the three-nucleon force. Methods based on the random-phase approximation (RPA) provide an optimal description of the modes of interest with minimal computational requirements. Here we discuss the giant resonances (GRs) of 40,48Ca isotopes and their low-energy dipole response. A comparison with previous results obtained with a transformed Argonne V18 two-nucleon potential points to certain improvements.

description: Analysis of three-particle correlations is performed on the basis of simulation data of atomic dynamics in liquid and amorphous aluminium. A three-particle correlation function is introduced to characterize the relative positions of various three particles -- the so-called triplets. Various configurations of triplets are found by calculation of pair and three-particle correlation functions. It was found that in the case of liquid aluminium with temperatures $1000\,$K, $1500\,$K, and $2000\,$K the three-particle correlations are more pronounced within the spatial scales, comparable with a size of the second coordination sphere. In the case of amorphous aluminium with temperatures $50\,$K, $100\,$K, and $150\,$K these correlations in the mutual arrangement of three particles are manifested up to spatial scales, which are comparable with a size of the third coordination sphere. Temporal evolution of three-particle correlations is analyzed by using a time-dependent three-particle correlation function, for which an integro-differential equation of type of the generalized Langevin equation is output with help of projection operators technique. A solution of this equation by means of mode-coupling theory is compared with our simulation results. It was found that this solution correctly reproduces the behavior of the time-dependent three-particle correlation functions for liquid and amorphous aluminium.

description: Recently, several exotic bosons have been confirmed as multi-quark states, but there are violent disputes about their inner structures, namely if they are molecular states or tetraquarks, or even mixtures of the two structures. It would be interesting to experimentally search for non-strange four-quark states with open charm or bottom which are lighter than $Λ_c$ or $Λ_b$. Reasonable arguments indicate that they are good candidates of pure molecular states $Dπ$ or $Bπ$ because pions are the lightest boson. Both $Bπ$ and $Dπ$ bound states do not decay via strong interaction. The $Bπ$ molecule may decay into $B^*$ by radiating a photon, whereas $Dπ$ molecule can only decay via weak interaction. In this paper we explore the mass spectra of $Bπ$ molecular statesby solving the corresponding B-S equation. Then the rate of radiative decay $|\frac{3}{2},\frac{1}{2}\rangle\to B^*γ$ is calculated and our numerical results indicate that the processes can be measured by the future experiment. We also briefly discuss the $Dπ$ case, due to the constraint of the final state phase space, it can only decay via weak interaction.

Hybrid modeling and prediction of dynamical systems

Publisher: name: arXiv
Year: 2017
Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: Scientific analysis often relies on the ability to make accurate predictions of a system's dynamics. Mechanistic models, parameterized by a number of unknown parameters, are often used for this purpose. Accurate estimation of the model state and parameters prior to prediction is necessary, but may be complicated by issues such as noisy data and uncertainty in parameters and initial conditions. At the other end of the spectrum exist nonparametric methods, which rely solely on data to build their predictions. While these nonparametric methods do not require a model of the system, their performance is strongly influenced by the amount and noisiness of the data. In this article, we consider a hybrid approach to modeling and prediction which merges recent advancements in nonparametric analysis with standard parametric methods. The general idea is to replace a subset of a mechanistic model's equations with their corresponding nonparametric representations, resulting in a hybrid modeling and prediction scheme. Overall, we find that this hybrid approach allows for more robust parameter estimation and improved short-term prediction in situations where there is a large uncertainty in model parameters. We demonstrate these advantages in the classical Lorenz-63 chaotic system and in networks of Hindmarsh-Rose neurons before application to experimentally collected structured population data.
Family Practices during Life-Threatening Illness: Exploring the Everyday, 2007-2008
Creators: name: Ellis, J., University Of Sheffield, School Of Health And Related Research (SCHARR)
Publisher: name: UK Data Service
Year: 2013

description: This is a qualitative data collection. These data were collected as part of a PhD project which explored the experiences of individuals living in a family where a member was dying or had a life-threatening illness. This was an ethnographic study which combined informal, in-depth interviews with nine families and participant observation on a hospice ward. Participant observations and the interviews from one family have not been archived due to consent restrictions; therefore the collection comprises data from eight families. Broadly the research aims were:
 to explore how everyday family life is pursued when someone in the family has a life-threatening or terminal illness

to ask what families are doing at this time

to examine how relationships, family practices, familial identities and everyday family lives are experienced - particularly how they are sustained and/or changed when families encounter illness, dying and death

to also consider how family lives are experienced in a less every day and familiar context, by asking what might be significant about a hospice inpatient ward as a setting for family life during the illness process and especially nearing the end-of-life

 This is a qualitative collection consisting of 57 semi-structured interview transcripts conducted during phase two of this four-phased study.

 This study aimed to examine to nature of British Conservatism and how it attracted votes from the working class electorate. The researcher, Alan Silver, wanted to find out the social background, attitudes towards politics and the Conservative's appeal to this particular population of voters. He interviewed working class Conservative voters' attitudes and opinions towards key fundamental social issues and compared this to working class Labour voters and how they differed. He concluded that part of the appeal of the party lay with its projected image of competence, paternalism and national protection. Moreover the party was often viewed in a deferential manner by these particular voters since the party appealed to conservative values on immigration and on law and order.

 The empirical material was gathered in four phases. Phase one included 604 interviews with working class voters, from six large English cities, who had voted at the previous general election for one of the two major political parties. The population sample was designed to be representative of the entire population of Great Britain: sociologically, politically and geographically. The second phase involved 50 informant--who had been interviewed in the first stage--being interviewed again in a more intense and prolonged way using open ended questioning. The initial phase provided a quantitative framework in which the data from the second qualitative collection phase could be placed. The rich qualitative data was used to enhance and illustrate the quantitative data, as well as providing a useful validity check. The third phase included a sample survey of 1,261 informants from the general electorate in 36 marginal constituencies taken during January, 1963. It was used to analyse the opinions of the working class Conservative voters during a period of significant political change. The fourth and final phase involved the re-interviewing of eight working class Conservatives in 1963 about their reactions to the Profumo affair. The interviewees in this phase had already been interviewed twice previously in the earlier phases. This enabled the researchers to create a case study from the fourth-phase interviews, a specific event which threw the Conservative leadership into question. Phase four and the quantitative data are not held at the UK Data Archive.

description: This Final Restoration Plan and Environmental Assessment (RP/EA) has been developed by the Natural Resource Trustees of the St. Lawrence River Environment (Trustees) to identify and evaluate restoration alternatives to compensate for injuries to natural resources and resource service losses resulting from historical releases of hazardous substances to the St. Lawrence River Environment from three industrial facilities in Massena, New York. This RP/EA addresses the following three projects (Collectively, defined as the “Akwesasne Water Access Projects”): 1. Raquette River Public Access: boat launch, nearshore fishing access, and parking. 2. St. Regis River - Sken:nen Park West: public access to St. Regis River from west bank. 3. St. Regis River - Sken:nen Park East: public access to St. Regis River in the vicinity of the former Hogansburg dam powerhouse and east bank. The Akwesasne Water Access Projects will partially compensate the public for ecological and recreational fishing losses resulting from these hazardous substance releases by restoring streambank habitat and public access to, and uses of, the St. Regis River and the Raquette River; and providing economic, cultural, educational, and recreational benefits to the Akwesasne and regional community. These rivers are tributaries to the St. Lawrence River, and are within the St. Lawrence River Environment. This Final RP/EA evaluates restoration alternatives, including a no action alternative, and incorporates information from both the 2013 St. Lawrence River Environment Trustee Council’s (SLETC) Restoration and Compensation Determination Plan and Environmental Assessment (RCDP/EA) for the St. Lawrence River Environment. The SLETC also uses relevant information from the 2015 National Oceanic and Atmospheric Administration (NOAA) Restoration Center’s Programmatic Environmental Impact Statement (PEIS) for habitat restoration activities in completing this impact analyses. The Trustees have determined that the proposed action - the Akwesasne Water Access Projects - is consistent with the RCDP/EA and Trustees’ restoration goals and objectives, meets the Trustees’ established restoration evaluation criteria, and is not expected to have any significant adverse environmental effects as defined under the National Environmental Policy Act (NEPA).
Morale and Home Intelligence Reports, 1941-1949
Morale and Home Intelligence Reports

 This is a qualitative data collection. It is comprised mainly of two different types of reports: quarterly morale reports for military personnel abroad and weekly home intelligence reports about UK civilians (only English civilian reports are held at the UK Data Archive).

 The Morale Committee for the Allied Forces Headquarters (AFHQ) sent out a directive in 1940 to (AFHQ) requesting quarterly morale reports. The goals of the reports were to study morale of soldiers in its broadest aspect and to coordinate and prepare quarterly morale reports for the War Office. The reports covered a variety of topics, including factors affecting morale, such as discipline of military personnel, confidence in leaders and equipment, mail censorship, living conditions, recreation, education, relationships, and personal finance. The reports are mainly written from a narrative voice, typically of a commanding officer, of the overall feeling of the military base. Sometimes these reports include quotations and extracts from mail correspondence.

 The home intelligence reports aimed to present an impartial assessment of public feelings about the war efforts. Information was collated through a variety of sources: regional intelligence officers compiled weekly reports based on interviews with UK residents, postal censorship prepared weekly reports based on correspondence, and police officers were asked to produce reports based on their observations.

description: We estimated the ortho-{\rm{H$_2$O}} abundances of G267.9--1.1, G268.4--0.9, G333.1--0.4 and G336.5--1.5, four of the brightest ortho-{\rm{H$_2$O}} sources in the southern sky observed by the Submillimeter Wave Astronomy Satellite (ortho-{\rm{H$_2$O}} 1$_{10}$ -- 1$_{01}$ line, 556.936~GHz). The typical molecular clumps in our sample have H$_2$ column densities of $10 ^{22}$ to $10 ^{23}${\,}cm$^{-2}$ and ortho-{\rm{H$_2$O}} abundances of 10$^{-10}$. Compared with previous studies, the ortho-{\rm{H$_2$O}} abundances are at a low level, which can be caused by the low temperatures of these clumps. To estimate the ortho-{\rm{H$_2$O}} abundances, we used the CS $J = 2 \to 1$ line (97.98095~GHz) and CS $J = 5 \to 4$ (244.93556~GHz) line observed by{ the} Swedish-ESO 15\,m Submillimeter Telescope (SEST) to calculate the temperatures of the clumps and the 350~$\upmu$m dust continuum observed by{ the} Caltech Submillimeter Observatory (CSO) telescope to estimate the H$_2$ column densities. The observations of {\rm{N$_2$H$^+$}} ($J = 1 \to 0$) for these clumps were also acquired by SEST and the corresponding abundances were estimated. The {\rm{N$_2$H$^+$}} abundance in each clump shows a common decreasing trend toward the center and {a} typical abundance range from 10$^{-11}$ to 10$^{-9}$.

description: This is a qualitative data collection. The Coventry and Liverpool Lives oral history project collected 58 oral history interviews with 21 men and women who have lived and worked in these cities since approximately 1945. The project aimed to explore how working-class men and women narrate their life histories and how social memory impacts on life stories told. By using the life history method of research change and continuity in the way people identify themselves across their life was captured. The interviews aimed to question the significance of 'affluence' amongst a group of working-class people in two economically diverse English cities after 1945. The interviews highlight the continued significance people place on class and gender to identify themselves even if at times definitions of the terms appear ambivalent. This collection contributes significantly to our understanding and knowledge of post-war everyday life. The interviews cover topics such as childhood, neighbourhood, home life, schooling, youth, leisure, first job, work history including periods of unemployment, National Service, marriage, motherhood, fatherhood and later life. Together they include people’s experiences prior to 1945, through the 1980s to the time of interviewing in 2008. Post-war migration to these cities from across the UK, Iran and the Punjab are represented. The collection fills a gap in sources of the period by focusing on Coventry and Liverpool, two cities that experienced severe bomb damage during the Second World War and subsequently significant social and economic change and redevelopment after1945. Peoples’ memories of the 1970s and 1980s when both cities experienced high unemployment and economic downturn due to the demise of industry and manufacturing are well detailed. Historians’ attention is shifting from the London centric image of the swinging sixties to consider more regional and local experiences of the post-war period. This collection will make a significant contribution to this new direction in British history.
