description: Landauer's principle sets fundamental thermodynamical constraints for classical and quantum information processing, thus affecting not only various branches of physics, but also of computer science and engineering. Despite its importance, this principle was only recently experimentally considered for classical systems. Here we employ a nuclear magnetic resonance setup to experimentally address the information to energy conversion in a quantum system. Specifically, we consider a three nuclear spins $S=1/2$ (qubits) molecule ---the system, the reservoir and the ancilla--- to measure the heat dissipated during the implementation of a global system-reservoir unitary interaction that changes the information content of the system. By employing an interferometric technique we were able to reconstruct the heat distribution associated with the unitary interaction. Then, through quantum state tomography, we measured the relative change in the entropy of the system. In this way we were able to verify that an operation that changes the information content of the system must necessary generate heat in the reservoir, exactly as predicted by Landauer's principle. The scheme presented here allows for the detailed study of irreversible entropy production in quantum information processors.
title: Postpartum haemorrhage: new insights from published trials and the development of novel management options
Creators: name: Aflaifel, Nasreen
Publisher: name: University of Liverpool Repository
Year: 2015

description: Postpartum haemorrhage (PPH) is the most common cause of maternal mortality leading to an estimated 86, 000 deaths/year. The most common cause of PPH is failure of the uterus to contract properly (uterine atony). Several measures have been introduced to prevent and treat atonic PPH, but in spite of active management of the third stage of labour (AMTSL), maternal deaths from PPH still occur. PPH can kill rapidly within two hours or less. PPH has long been recognised as a dangerous complication for mothers. In order to optimise the prevention and treatment of PPH, different approaches have been introduced and modified over the last century. We reviewed the regimes used in the management of the third stage of labour between 1917 and 2011 as described in the successive editions of the ‘Ten Teachers’ books. Throughout the Ten Teachers series, uterotonic drugs have always been taught as being the best initial measure to manage PPH. However, the importance of bimanual uterine compression (BMC) has increased gradually, moving from third to first treatment option over the editions (Aflaifel and Weeks, 2012a). The components of the AMTSL package for PPH prophylaxis have recently been extensively examined in clinical trials. Its effectiveness in reducing blood loss is now known to be almost all due to the uterotonics (Aflaifel and Weeks, 2012b). However, clinical trials evaluating the efficacy of uterotonics in treating PPH are comparatively rare. Where present they usually compare two uterotonics with an absence of control group, as it is unethical to leave a bleeding woman untreated. A recent innovation is to model the likely outcomes in the absence of uterotonic therapy through histograms. This also allows an assessment of the efficiency of treatment by measuring the number of women who stop bleeding shortly after administering treatments. This model has never previously been applied to databases in which uterotonics were used for prophylaxis. In a secondary analysis of 4 large randomised trials, small secondary histogram peaks (primarily attributed to a treatment effect) were still present even if uterotonic therapy had not been used. Furthermore, the study revealed that women were commonly treated at low levels of blood loss (

description: We study local asymptotic properties of likelihood ratios of certain Heston models. We distinguish three cases: subcritical, critical and supercritical models. For the drift parameters, local asymptotic normality is proved in the subcritical case, only local asymptotic quadraticity is shown in the critical case, while in the supercritical case not even local asymptotic quadraticity holds. For certain submodels, local asymptotic normality is proved in the critical case, and local asymptotic mixed normality is shown in the supercritical case. As a consequence, asymptotically optimal (randomized) tests are constructed in cases of local asymptotic normality. Moreover, local asymptotic minimax bound, and hence, asymptotic efficiency in the convolution theorem sense are concluded for the maximum likelihood estimators in cases of local asymptotic mixed normality.

description: Supercooling of water can be easily studied with a simple apparatus suitable for the student laboratory. We describe such an apparatus and its capabilities. The parameters influencing supercooling include the initial temperature of the water and the temperature and the type of chilling medium. We correlate the occurrence of supercooling with the ability of the chilling medium to promptly nucleate ice; if it nucleates promptly, the layer of ice crystals formed on the boundary will initiate freezing of the bulk water without supercooling. If the chilling medium is unable to nucleate ice promptly, ice nucleation is delayed and the water supercools. Students can study and compare supercooling of distilled and natural water. Even quite dirty river water may be supercooled by as much as 5 C.

description: Through a reciprocal transformation $\mathcal{T}_0$ induced by the conservation law $\partial_t(u_x^2) = \partial_x(2uu_x^2)$, the Hunter-Saxton (HS) equation $u_{xt} = 2uu_{2x} + u_x^2$ is shown to possess conserved densities involving arbitrary smooth functions, which have their roots in infinitesimal symmetries of $w_t = w^2$, the counterpart of the HS equation under $\mathcal{T}_0$. Hierarchies of commuting symmetries of the HS equation are studied under appropriate changes of variables initiated by $\mathcal{T}_0$, and two of these are linearized while the other is identical to the hierarchy of commuting symmetries admitted by the potential modified Korteweg-de Vries equation. A fifth order symmetry of the HS equation is endowed with a sixth order hereditary recursion operator by its connection with the Fordy-Gibbons equation. These results reveal the origin for the rich and remarkable structures of the HS equation and partially answer the questions raised by Wang [{\it Nonlinearity} {\bf 23}(2010) 2009].

description: Mit dem in dieser Arbeit vorgestellten Photobioreaktor sollen die Nachteile der klassischen Photobioreaktortypen umgangen und eine Möglichkeit der ökonomischen Produktion von Mikroalgenbiomasse geschaffen werden. Durch die Zick-Zack-Struktur der Oberfläche des hier behandelten Horizontalreaktors soll die Lichtenergie auf moderate Level verdünnt werden, so dass die Mikroalgen keinen inhibierenden Strahlungsintensitäten ausgesetzt sind und die Energie effizient umsetzen können. Zur Validierung dieser Behauptung wurde eine Simulation der Energieeinträge auf der Oberfläche des Zick-Zack-Reaktors durchgeführt. Als Vergleich wurde eine Simulation einer Freiland-Kultivierung in einem Plattenreaktor herangezogen, die mit empirisch bestimmten Daten belegt wurde. Die Basis für diese Simulationen bildeten in Labor-Reaktoren ermittelte Zeitkonstanten des Chlorophyllgehalts der Mikroalgen in Abhängigkeit der Photonenflussdichte sowie eine Regression des Absorptionskoeffizienten bei adaptierten Lichtintensitäten und Chlorophyllanteilen. Neben der Lichtverteilung im Photobioreaktor ist der Stofftransport, genauer die CO2-Versorgung und O2-Abreicherung, ein wichtiger Faktor zur Produktivitätssteigerung. Zur Auslegung der Begasung des Reaktors wurden zunächst empirisch volumetrische Stoffübergangskoeffizienten der im Reaktor integrierten Oberflächenbegasung ermittelt und der Stofftransport in einer CFD-Simulation modelliert. Ausgehend von diesen Erkenntnissen wurden Membrankontaktoren über fundierte Transportgleichungen ausgelegt und in das System integriert.

description: Surface plasmon polaritons (SPPs) give an opportunity to break the diffraction limit and design nanoscale optical components, however their practical implementation is hindered by high ohmic losses in a metal. Here, we propose a novel approach for efficient SPP amplification under electrical pumping in a deep-subwavelength metal-insulator-semiconductor waveguiding geometry and numerically demonstrate full compensation for the SPP propagation losses in the infrared at an exceptionally low pump current density of 0.8 kA/cm$^2$. This value is an order of magnitude lower than in the previous studies owing to the thin insulator layer between a metal and a semiconductor, which allows injection of minority carriers and blocks majority carriers reducing the leakage current to nearly zero. The presented results provide insight into lossless SPP guiding and development of future high dense nanophotonic and optoelectronic circuits.

title: Evaluating professionalism, teamwork and leadership in medical undergraduates

Publisher: name: University of Liverpool Repository
Year: 2015

description: The complexity of healthcare is increasing due to new discoveries in the treatment of disease, the multiple pathologies of an ageing population and changes in working patterns and job roles. In addition, an increase in professional, regulatory and public scrutiny has led to revelations of poor care leading to preventable disability and death. Inquiries into sub-standard care have uncovered a number of professional lapses, in particular failures in teamwork and leadership. Medical undergraduates are future doctors. Their ability to work effectively within teams and to lead when necessary will therefore have a significant impact on the health of the population. In order to improve leadership and teamwork abilities we must be able to assess them. A literature review searching for a tool to assess teamwork and leadership in the medical undergraduate was carried out. As a consequence of an unsuccessful search, a tool was developed and evaluated, using data from existing tools and from a series of focus groups with medical undergraduates. The focus groups and an examination of the reasoning of assessment participants also informed a study on the justifications for failing to challenge poor performance by a more senior member of staff. The tool data showed adequate validity and reliability for formative assessments in a simulated environment. The focus groups and examination of reasoning highlighted the continued existence of the medical hierarchy, with steep authority gradients. This tool can be used in formative assessments, but further research is required before it is used outside the simulated environment and consideration must be given to psychometrics, feasibility and cost. The teaching and assessment of teamwork and leadership, should be given more time in the undergraduate curriculum and medical schools, regulatory bodies, deaneries and trusts should collaborate on minimising the unprofessional behaviours of senior healthcare personnel.

description: Recent advances in the development of modern quantum technologies have opened the possibility of studying the interplay between spontaneous parametric down-conversion and optomechanics, two of the most fundamental nonlinear optical processes. Apart from practical reasons, such scenario is very interesting from a fundamental point of view, because it allows exploring the optomechanical interaction in the presence of a strongly quantum-correlated field, the spontaneously down-converted mode. In this work we analyze such problem from two approximate but valuable perspectives: the classical limit and the limit of small quantum fluctuations. We show that, in the presence of optomechanical coupling, the well-known classical phase diagram of the optical problem gets modified by the appearance of new dynamical instabilities. As for the quantum-mechanical description, we prove the ability of the squeezed down-converted field to cool down the mechanical motion not only to thermal but also to squeezed thermal mechanical states, and in a way that can be much less sensitive to parameters (e.g., detuning of the driving laser) than standard sideband cooling.

title: Understanding the experiences of Pakistani educated nurses working in the United Kingdom: a phenomenological approach
Creators: name: Muhammad, Dildar
Publisher: name: University of Liverpool Repository
Year: 2015

description: Aim: The purpose of this study was to explore the lived experience of migrant Pakistani nurses working in the United Kingdom. Background: Pakistani educated nurses have a history of migration to Middle Eastern and developed countries, and despite severe nurse shortages the Pakistan government has no strategy to retain these professionals. Pakistan saw an unprecedented shortage of nurses during the years 2000-2007 when about 1200 nurses migrated to the United Kingdom. This nursing ‘brain drain’ has negatively impacted on the health system in Pakistan, leaving it depleted of experienced health workers. Nevertheless, what motivates Pakistani nurses to migrate, and post migration experiences of these nurses are not known. Methods: This study adopted the principles of hermeneutic phenomenology to explore the lived experience of Pakistani educated nurses working in the UK. A total of twenty one Pakistani nurses working and residing in the Northwest, Yorkshire and East Midlands of England were interviewed, including eleven females and ten male participants. In-depth face to face interviews were conducted with participants, supplemented by demographic information sheets, observations, and field notes. Analysis was carried out using van Manen’s thematic approach. Findings: Findings of the study reveal the complex nature of the ‘life world’ of participants and both dismal as well as affirmative experiences were revealed. The three major themes which emerged from the study findings were ‘Becoming a Migrant’, ‘Dissonance and Devaluation’ and ‘Outsider Identities’. The lived experience of nurses showed physical and emotional hardships in Pakistan that pushed them to leave the country and move abroad. Once migrated to the United Kingdom, these nurses started their careers in elderly care homes and found themselves devalued and deskilled. In addition, their lived experience included feelings of being isolated and alienated in the UK. Discussion: The meaning of study findings reveals the concept of ‘otherness’ as core to understanding these experiences in the socio-cultural and geo-political context of the study. The meaning of Pakistani migrant nurses’ lived experience is linked to marginalization, the politics of identity and belonging. The study is one of the first to describe the notion of ‘otherness’ as a means of understanding nurse migration, and adds to knowledge of the phenomenon of ‘otherness’ as it is lived and constructed. This study has also given voice to a small group of Pakistani migrant nurses who have otherwise been marginalised by their society, their profession and their migration to the UK.

description: While astrochemical models are successful in reproducing many of the observed interstellar species, they have been struggling to explain the observed abundances of complex organic molecules. Current models tend to privilege grain surface over gas phase chemistry in their formation. One key assumption of those models is that radicals trapped in the grain mantles gain mobility and react on lukewarm (>30 K) dust grains. Thus, the recent detections of methyl formate (MF) and dimethyl ether (DME) in cold objects represent a challenge and may clarify the respective role of grain surface and gas phase chemistry. We propose here a new model to form DME and MF with gas phase reactions in cold environments, where DME is the precursor of MF via an efficient reaction overlooked by previous models. Furthermore, methoxy, a precursor of DME, is also synthetized in the gas phase from methanol, which is desorbed by a non-thermal process from the ices. Our new model reproduces fairy well the observations towards L1544. It also explains, in a natural way, the observed correlation between DME and MF. We conclude that gas phase reactions are major actors in the formation of MF, DME and methoxy in cold gas. This challenges the exclusive role of grain-surface chemistry and favours a combined grain-gas chemistry.

title: Development of advanced radiation monitors for pulsed neutron fields
Creators: name: Manessi, Giacomo Paolo
Publisher: name: University of Liverpool Repository
Year: 2016

description: The need of radiation detectors capable of efficiently measuring in pulsed neutron fields is attracting widespread interest since the 60s. The efforts of the scientific community substantially increased in the last decade due to the increasing number of applications in which this radiation field is encountered. This is a major issue especially at particle accelerator facilities, where pulsed neutron fields are present because of beam losses at targets, collimators and beam dumps, and where the correct assessment of the intensity of the neutron fields is fundamental for radiation protection monitoring. LUPIN is a neutron detector that combines an innovative acquisition electronics based on logarithmic amplification of the collected current signal and a special technique used to derive the total number of detected neutron interactions, which has been specifically conceived to work in pulsed neutron fields. Due to its special working principle, it is capable of overcoming the typical saturation issues encountered in state-of-the-art detectors, which suffer from dead time losses and often heavily underestimate the true neutron interaction rate when employed for routine radiation protection measurements. This thesis presents a comprehensive study into the design, optimisation and operation of two versions of LUPIN, based on different active gases. In addition, two other devices, a beam loss monitor and a neutron spectrometer, which have been built using LUPIN’s acquisition electronics, are also discussed in detail. Experimental results obtained in a number of facilities where the detectors have been exposed to most diverse and extreme conditions are shown in order to demonstrate the superior instrument performance in a critical assessment with commercial devices commonly employed for personnel and machine protection.
title: Functionalised microporous organic polymers as adsorbents
Creators: name: Ratvijitvech, Thanchanok
Publisher: name: University of Liverpool Repository
Year: 2015

description: Microporous organic polymers (MOPs) are materials made from organic monomers that have a pore width smaller than 2 nm. Due to their high porosity and diversity of functional group, MOPs have potential in broad ranges of applications. As well as absolute surface area, the functional groups also play an important role in the design and synthesis of materials for desired utilisations. In this work, we demonstrate strategies to synthesise functionalised networks to be utilised as sorbents. The focus is on hypercross-linked polymers (HCPs) and conjugated microporous polymers (CMPs), which are amorphous networks and subclasses of MOPs. Different strategies including copolymerisation, post-cross-linking of functionalised linear polymer chains, and post-synthetic modification (PSM) were found able to incorporate different functional groups into the networks. The structures and properties of the networks could be fine tuned. The networks were investigated for applications in CO2 capture and separations as well as molecular imprinting polymers (MIPs).

description: The paper examines changes in the relationship between employment and household tasks of Japanese couples, using data drawn from national cross-sectional surveys in 1994, 2000 and 2009 of persons aged 20–49 and from the 2009 follow-up of the 2000 survey. Wives’ employment is structured by their husbands’ employment time and earning power, as well as by their family situations including the presence and age of children and coresidence with parents. Housework hours of husbands, though very low, increased over time, while wives’ hours decreased. Wives housework time decreases as their employment time increases. Marriage dramatically increases women’s housework time but produces little change in men’s time. Husbands’ housework hours are positively correlated with reported marital satisfaction of both spouses.

description: In the context of count-in-cells statistics, the joint probability distribution of the density in two concentric spherical shells is predicted from first first principle for sigmas of the order of one. The agreement with simulation is found to be excellent. This statistics allows us to deduce the conditional one dimensional probability distribution function of the slope within under dense (resp. overdense) regions, or of the density for positive or negative slopes. The former conditional distribution is likely to be more robust in constraining the cosmological parameters as the underlying dynamics is less evolved in such regions. A fiducial dark energy experiment is implemented on such counts derived from Lambda-CDM simulations.

description: Purpose Stroke is a leading cause of death and disability worldwide. Despite the prevalence and associated burden of post-stroke cognitive impairment, there is uncertainty regarding optimum interventions to improve cognitive function in people post-stroke. The aim of this study is to explore the perspectives of key stakeholders on the design and development of a multi-disciplinary intervention to rehabilitate cognitive deficits in people post-stroke. Materials and methods Audio-recorded, semi-structured interviews were employed with people post-stroke, care-givers, healthcare professionals and academics. All transcribed interviews were exported to NVivo software and analysed using reflexive thematic analysis. Results Thirty interviews were conducted across stakeholder groups including people post-stroke (n = 10), caregivers (n = 5), healthcare professionals (n = 14) and academics (n = 1). Four themes relevant to the design and development of the intervention were identified (i) engagement in the intervention must be meaningful, (ii) the point of readiness to engage, (iii) a familiar but flexible setting is key (iv) pragmatics of intervention delivery. Conclusions These findings present new perspectives across stakeholder groups on the design and delivery of an intervention to rehabilitate cognitive deficits in people post-stroke. Taken together with existing quantitative evidence, these findings will inform the development of a feasibility trial, examining patient and process outcomes, to rehabilitate cognitive deficits post-stroke.
title: Cairns in context: GIS analysis of visibility at Stelae Ridge, Egypt.
Creators: name: Pethen, Hannah
Publisher: name: University of Liverpool Repository
Year: 2015

description: This thesis describes a new approach tor investigating cairns, stone enclosures, stone alignments and other small archaeological features found in the deserts around the Egyptian Nile valley. Investigation of these features has previously been restricted by their ephemeral nature, damage from modern development and the limited artefactual, epigraphic or archaeological evidence associated with them. This research focuses on a case study of eight cairns and adjacent courts at the Middle Kingdom carnelian mine of Stelae Ridge in the Gebel el-Asr quarries in southern Egypt. While accepting previous interpretations of the cairn-courts as ritual structures created for the worship of local divinities, this research sought a fuller interpretation of the site in its landscape context and a more nuanced understanding of the structures, their chronological development and the decisions which governed their location and layout. This was achieved through systematic visibility analysis of the eight cairn-courts with geographic information system (GIS) software, which provided new data concerning the patterns of visibility associated with the structures. Interpretation of these patterns in the context of the archaeological and textual evidence from the cairn-courts, practical experience of visibility at the site and evidence from the wider cultural context provided a new and more detailed understanding of the site. Stelae Ridge was chosen because cairns upon it made highly visible landmarks, particularly for people travelling south towards the other sites in the Gebel el-Asr gneiss quarrying region. Initially practical, the Stelae Ridge cairns also developed a ritual function, creating tension between the highly visible cairns and the secluded ritual courts, and suggesting that the cairn-building process became ritualised. By the end of the cairn-building period, in the reign of Amenemhat III, new cairns were constructed in less visible positions, suggesting that the ritual aspects of the cairn-courts had largely subsumed their earlier practical function as landmarks. This type of GIS research has never been undertaken on Egyptian archaeological sites and previous interpretations of visibility in Egyptian contexts have been limited. The detailed interpretation of the Stelae Ridge cairn-courts achieved here, shows that the technology and approach applied to this research can make a meaningful contribution to the investigation of other similar non-formal structures, and at Egyptian sites in general. It also reveals that GIS visibility analysis can answer relevant archaeological questions, when employed as a tool for data generation and properly contextualised with other evidence from the site.

title: Theoretical and numerical study on optimal mortgage refinancing strategy
Creators: name: Zheng, Jin
Publisher: name: University of Liverpool Repository
Year: 2016

description: This work studies optimal refinancing strategy for the debtors on the view of balancing the profit and risk, where the strategy could be formulated as the utility optimization problem consisting of the expectation and variance of the discounted profit if refinancing. An explicit solution is given if the dynamic of the interest rate follows the affine model with zero-coupon bond price. The results provide some references to the debtors in dealing with refinancing by predicting the value of the contract in the future. Special cases are considered when the interest rates are deterministic functions. Our formulation is robust and applicable to all of the short rate stochastic processes satisfying the affine models.

description: Both sociological and economic theories posit that widely available, high-quality, and affordable child care should have pronatalist effects. Yet to date, the empirical evidence has not consistently supported this hypothesis. We argue that this previous empirical work has been plagued by the inability to control for endogenous placement of day care centers and the possibility that people migrate to take advantage of the availability of child care facilities. Using Norwegian register data and a statistically defensible fixed-effects model, we find strong positive effects of day care availability on the transition to motherhood.

description: In many demographic behaviors (e.g., those relating to marriage, contraception, migration, and health), people change among multiple statuses through time, sometimes leaving and then returning to the same status. Data on such behaviors are often collected in surveys as censored event histories. The multistate life table (MSLT) can be used to properly describe, in a single analysis, these complex transitions among multiple states measured in such data, but MSLT is rarely applied in the demographic literature because practical guidance is lacking on how to compute MSLTs with such data. We provide methods for computing MSLT quantities using censored event-history data: namely, transition intensities and probabilities, “state occupancy” probabilities and standard errors, average time spent in specified states, and average number of visits to specified states. Applying these methods to contraceptive use, we find high levels of switching back and forth, particularly between barrier methods and non-use, resulting in high rates of unintended pregnancy.

An Integrative Approach to Health

description: In this article, I make the case for using an integrative approach to health, broadly defined as social, emotional, mental, and physical well-being; for studying health among the young as an important marker for future health and well-being across the life course; and for understanding health disparities among the young as both causes and consequences of social stratification. An integrative approach bridges biomedical sciences with social and behavioral sciences by understanding the linkages between social, behavioral, psychological, and biological factors in health. It is furthermore vital that integration occur in all steps of the research process: in theory, design, data collection, and analysis. I use the National Longitudinal Study of Adolescent Health, or Add Health, as an example of an integrative approach to health and of the importance of adolescence and the transition to adulthood years for setting health trajectories into adulthood. Evidence is also presented on the linkages between health trajectories during adolescence and the transition to adulthood and social stratification in adulthood.
On the optimal estimates and comparison of Gegenbauer expansion coefficients

description: In this paper, we study optimal estimates and comparison of the coefficients in the Gegenbauer series expansion. We propose an alternative derivation of the contour integral representation of the Gegenbauer expansion coefficients which was recently derived by Cantero and Iserles [SIAM J. Numer. Anal., 50 (2012), pp.307-327]. With this representation, we show that optimal estimates for the Gegenbauer expansion coefficients can be derived, which in particular includes Legendre coefficients as a special case. Further, we apply these estimates to establish some rigorous and computable bounds for the truncated Gegenbauer series. In addition, we compare the decay rates of the Chebyshev and Legendre coefficients. For functions whose singularity is outside or at the endpoints of the expansion interval, asymptotic behaviour of the ratio of the nth Legendre coefficient to the nth Chebyshev coefficient is given, which provides us an illuminating insight for the comparison of the spectral methods based on Legendre and Chebyshev expansions.

Childhood Nutrition and Later Fertility: Pathways Through Education and Pre-Pregnant Nutritional Status

description: Better childhood nutrition is associated with earlier physical maturation during adolescence and increased schooling attainment. However, as earlier onset of puberty and increased schooling can have opposing effects on fertility, the net effect of improvements in childhood nutrition on a woman’s fertility are uncertain. Using path analysis, we estimate the strength of the pathways between childhood growth and subsequent fertility outcomes in Guatemalan women studied prospectively since birth. Height for age z score at 24 months was positively related to body mass index (BMI kg/m2) and height (cm) in adolescence and to schooling attainment. BMI was negatively associated (−0.23 ± 0.09 years per kg/m2; p < .05) and schooling was positively associated (0.38 ± 0.06 years per grade; p < .001) with age at first birth. Total associations with the number of children born were positive from BMI (0.07 ± 0.02 per kg/m2; p < .05) and negative from schooling (−0.18 ± 0.02 per grade; p < .01). Height was not related to age at first birth or the number of children born. Taken together, childhood nutrition, as reflected by height at 2 years, was positively associated with delayed age at first birth and fewer children born. If schooling is available for girls, increased growth during childhood will most likely result in a net decrease in fertility.

description: Investigations of socioeconomic status (SES) and health during the transition to adulthood in the United States are complicated by the later and more varied transitions in residence, employment, schooling, and social roles compared with previous generations. Parental SES is an important influence during adolescence but cannot sufficiently capture the SES of the independent young adult. Typical, single SES indicators based on income or education likely misclassify the SES of young adults who have not yet completed their education or other training, or who have entered the labor force early with ultimately lower status attainment. We use a latent class analysis (LCA) framework to characterize five intergenerational SES groups, combining multidimensional SES information from two time points—that is, adolescent (parental) and young adult (self) SES data. Associations of these groups with obesity, a high-risk health outcome in young adults, revealed nuanced relationships not seen using traditional intergenerational SES measures. In males, for example, a middle-class upbringing in adolescence and continued material advantage into adulthood was associated with nearly as high obesity as a working poor upbringing and early, detrimental transitions. This intergenerational typology of early SES exposure facilitates understanding of SES and health during young adulthood.
