description: Sorting target bio-cells like RBC, WBC, and CTCs from complex samples into a high-purity product is challenging yet essential for downstream cell biology research and clinical diagnostics. Conventional active particle sorting approaches include centrifugation and fluorescent activated cell sorting (FACS), both of which may cause contamination and loss of target cells. On the contrary, the rising field of inertial microfluidics brought light to label-free passive particle sorting, which also eliminates potential cell-damaging procedures.
title: Experimental evolution of parasite life history in bacteriophage Φ2
Creators: name: Truman, Julie
Publisher: name: University of Liverpool Repository
Year: 2015

description: Parasite life history theory predicts that lifetime reproductive success evolves through differential allocation of energy to life history traits constrained by trade-offs. These life history traits govern the characteristics of parasites such as their virulence, transmission and infection phenotypes, so understanding their evolution is a key concern for infectious disease prediction and management. This thesis uses the powerful tool of experimental evolution to gain a fuller understanding of the factors and constraints involved in parasite life history evolution, using bacteriophage Φ2 as a model. I found that the evolution of life history in this phage is sensitive to spatial structure, UV-C exposure and coparasitism with plasmids, and evolution can be mediated by co-evolution with the host. The high levels of variance I observed here suggest that evolution of parasite life history is more complex than a single trajectory towards a predicted optimum, and likely involves some degree of epistasis or pleiotropy with genes elsewhere on the genome. There was some degree of independent evolution of individual life-history traits, indicating that simple direct trade-offs were not in operation. I demonstrated that co-evolution with the host provided additional mutational input, resulting in a greater degree of evolution in co-evolved populations than those evolved to a static host. Furthermore, I note that co-parasitism with phage and plasmid may provide the necessary conditions for plasmid persistence under fluctuating selection for plasmid-encoded traits, and that the efficacy and suitability of phage as therapeutic agents against plasmid-encoded antibiotic resistance is complicated. No direct link between mutation and phenotype could be elucidated in this study, suggesting that evolution in life history is either governed by genes not examined in this thesis, or involves epistasis and pleiotropy with genes elsewhere on the genome. I concluded that it is important to consider the specific ecology of the focal parasite, its host and any co-occuring symbionts in order to make informed predictions of life history evolution, and general predictions may not be achievable.
title: A Platonic Defence of Realism in Quantum Theory
Creators: name: Halley Spencer, John
Publisher: name: University of Liverpool Repository
Year: 2023

description: In this thesis, contrary to the common assumption that quantum theory is positivist and antirealist, I argue that it is best understood as being Platonic. There has been a constant confusion of terms whereby realism has been equated with materialism and determinism, so that the denial of these metaphysical notions has led to the false conclusion that quantum theory is antirealist. However, there are many different uses of the terms 'realism', 'antirealism' and 'idealism'. When such confusion has been clarified and we have taken seriously the philosophical views of the founders of quantum theory coupled with appropriate metaphysical reasoning, we can understand how the new physics still presupposes and implies the truth of essential aspects of Platonism. Two important examples are that physics (classical and quantum) presupposes the notion of a unified, hierarchically ordered universe, and that what is most real or fundamental in physics is the ideal. The ideal laws of physics must have some sort of existence (or being) prior to their discovery, and the best explanation for their ontological status and our access to them is to be found in Platonic realism. The basic realist assumption that we discover nonphysical objective truths has rarely in the contemporary literature been given a serious metaphysical defence. The ontological and epistemological difficulties permeating the underlying.assumption that an apparently physical, finite, and perpetually changing sentient creature can have access to nonphysical, eternal, and constant truths (whether in the mathematical laws of physics or morality) are almost ubiquitously ignored. Such a denial unavoidably leads to irresolvable conceptual dilemmas, which become obvious in the philosophical and empirical foundations of quantum theory. We are thus justified in demanding a philosophical defence, and I argue that only a properly understood Platonic metaphysics is capable of such a formidable task. . I challenge many nai've implicit assumptions in both contemporary analytic philosophy and the common experience of the experimental physicist who completely relies upon the pioneering work of the great physicists, from the founders of modern science four hundred years ago to Einstein, Planck, Heisenberg, Bohr, Schrodinger, and Pauli among others. It is only through understanding that such eminent pioneers were necessarily involved with deep metaphysical questions while developing the new physics that we can begin to appreciate and come to understand the various conceptual difficulties in quantum theory. It is a reasonable presumption that without such philosophical understanding, fundamental advances in the sciences will not be possible and pure research will dwindle. And without pure research, applied research will sooner or later be essentially nonexistent, or completely trivial. Supplied by The British Library - 'The world's knowledge'

description: The present study investigated developmental differences in the effects of repeated interviews and interviewer bias on children’s memory and suggestibility. Three- and 5-year-olds were singly or repeatedly interviewed about a play event by a highly biased or control interviewer. Children interviewed once by the biased interviewer after a long delay made the most errors. Children interviewed repeatedly, regardless of interviewer bias, were more accurate and less likely to falsely claim that they played with a man. In free recall, among children questioned once after a long delay by the biased interviewer, 5-year-olds were more likely than were 3-year-olds to claim falsely that they played with a man. However, in response to direct questions, 3-year-olds were more easily manipulated into implying that they played with him. Findings suggest that interviewer bias is particularly problematic when children’s memory has weakened. In contrast, repeated interviews that occur a short time after a to-be-remembered event do not necessarily increase children’s errors, even when interviews include misleading questions and interviewer bias. Implications for developmental differences in memory and suggestibility are discussed.

description: This longitudinal study was designed to (i) examine changes in children’s deliberate memory across the first grade; (ii) characterize the memory-relevant aspects of their classrooms; and (iii) explore linkages between the children’s performance and the language their teachers use in instruction. In order to explore contextual factors that may facilitate the development of skills for remembering, 107 first graders were assessed three times with a broad set of tasks, while extensive observations were made in the 14 classrooms from which these children were sampled. When the participating teachers were classified as high or low in terms of their “mnemonic orientation,” in part on the basis of their use of metacognitive information and requests for deliberate remembering during instruction in language arts and mathematics, differences were observed in the use of mnemonic techniques by the children in their classes. By the end of the year, the children drawn from these two groups of classrooms differed in their spontaneous use of simple behavioral strategies for remembering and in their response to training in more complex verbally-based mnemonic techniques.

description: A robust controller is developed for uncertain, second-order nonlinear systems subject to simultaneous unknown, time-varying state delays and known, time-varying input delays in addition to additive, sufficiently smooth disturbances. An integral term composed of previous control values facilitates a delay-free open-loop error system and the development of the feedback control structure. A stability analysis based on Lyapunov-Krasovskii (LK) functionals guarantees uniformly ultimately bounded tracking under the assumption that the delays are bounded and slowly varying.

description: There are a number of significant challenges encountered when studying development over an extended period of time including subject attrition, changing measurement structures across group and developmental period, and the need to invest substantial time and money. Integrative data analysis is an emerging set of methodologies that overcomes many of the challenges of single sample designs through the pooling of data drawn from multiple existing developmental studies. This approach is characterized by a host of advantages, but this also introduces several new complexities that must be addressed prior to broad adoption by developmental researchers. In this paper we focus on methods for fitting measurement models and creating scale scores using data drawn from multiple longitudinal studies. We present findings from the analysis of repeated measures of internalizing symptomatology that were pooled from three existing developmental studies. We describe and demonstrate each step in the analysis and we conclude with a discussion of potential limitations and directions for future research.

description: Dissipative forces are ubiquitous and thus constitute an essential part of realistic physical theories. However, quantization of dissipation has remained an open challenge for nearly a century. We construct a quantum counterpart of classical friction, a velocity-dependent force acting against the direction of motion. In particular, a translationary invariant Lindblad equation is derived satisfying the appropriate dynamical relations for the coordinate and momentum (i.e., the Ehrenfest equations). Numerical simulations establish that the model approximately equilibrates. These findings significantly advance a long search for a universally valid Lindblad model of quantum friction and open opportunities for exploring novel dissipation phenomena.

title: The experiences of fathers who found childbirth traumatic
Creators: name: Etheridge, Jody
Publisher: name: University of Liverpool Repository
Year: 2015

description: This thesis takes as its focus the experiences of men who attend childbirth; presenting a meta-synthesis of literature on the experiences of fathers in routine delivery before moving on to an empirical paper researching the experiences of fathers who have experienced childbirth as traumatic. Chapter One presents a meta-synthesis of empirical research into fathers’ experiences of being present at the birth of their child. The trend for men’s presence at childbirth and the early literature are discussed. A systematic literature search and meta-ethnographic approach to synthesis are described. The paper draws together common themes and metaphors from eleven qualitative studies into a synthesis regarding what fathers view as significant aspects of their experience at childbirth. The findings are discussed with regard to masculine ideologies, constructs of roles, self-efficacy and the role of maternity services in caring for fathers. Consideration is given to births which men may find difficult, which leads to Chapter Two. Chapter Two is an empirical paper exploring the experiences of men who found the childbirth traumatic. A qualitative methodology was employed using semi-structured interviews and template analysis, drawing out aspects of men’s experiences, coping strategies and the subsequent impact of trauma on their lives. The findings are discussed in terms of psychological constructs, particularly theories of stress and coping. The paper contributes to the existing literature through highlighting new findings as to how fathers experience and try to cope with a traumatic birth. Consideration is given to the clinical implications of the research and suggestions for further research are offered. Both papers were prepared for publication: the literature review for the International Journal of Nursing Studies and the empirical paper for the Journal of Clinical Psychology in Medical Settings.

description: The present study examined ethnic, gender and age differences in perceived discrimination, and the association between perceived discrimination and psychological well-being in a nationally representative sample of Black adolescents. Data are from the National Survey of African Life (NSAL), which includes 810 African American and 360 Caribbean Black youth. Results indicate that the majority of Black youth perceived at least one discriminatory incident in the previous year. Adolescents at later stages of development perceived more discrimination than those at earlier stages, and African American and Caribbean Black males perceived more discrimination than their female counterparts. Perceptions of discrimination were positively linked to depressive symptoms and negatively linked to self-esteem and life satisfaction, regardless of ethnicity. However, Caribbean Black youth appear to be more vulnerable when they perceive high levels of discrimination.

description: The present study examined whether combinations of ethnicity, gender and age moderated the association between perceived discrimination and psychological well-being indicators (depressive symptoms, self-esteem and life satisfaction) in a nationally representative sample of Black youth. The data were from the National Survey of African Life (NSAL), which includes 810 African American and 360 Caribbean Black adolescents. The results indicated main effects such that perceived discrimination was linked to increased depressive symptoms, and decreased self-esteem and life satisfaction. Additionally, there were significant interactions for ethnicity, gender and race. Specifically, older Caribbean Black females exhibited higher depressive symptoms and lower life satisfaction in the context of high levels of perceived discrimination compared to older African American males.

description: Although frequent calls are made for the study of effects of children on families and mutual influence processes within families, little empirical progress has been made. We address these questions at the level of micro processes during marital conflict, including children’s influence on marital conflict and parents’ influence on each other. Participants were 111 cohabiting couples with a child (55 males, 56 females) aged 8 – 16 years. Data were drawn from parents’ diary reports of interparental conflict over 15 days, analyzed using dynamic systems modeling tools. Child emotions and behavior during conflicts were associated with interparental positivity, negativity, and resolution at the end of the same conflicts. For example, children’s agentic behavior was associated with more marital conflict resolution whereas child negativity was linked with more marital negativity. Regarding parents’ influence on each other, among the findings, husbands’ and wives’ influence on themselves from one conflict to the next was indicated, and total number of conflicts predicted greater influence of wives’ positivity on husbands’ positivity. Contributions of these findings to the understanding of developmental family processes are discussed, including implications for advanced understanding of interrelations between child and adult functioning and development.
title: Dusty, Cilla, Sandie, Lulu as seen on TV : a study of interrelations between pop music, television and fashion
Creators: name: Lowy, Adrienne
Publisher: name: University of Liverpool Repository
Year: 2023

description: This thesis examines the way in which four British female performers, Dusty Springfield, Cilla Black, Sandie Shaw and Lulu, forged a relationship between pop music, television and fashion at a key moment in time, the period 1963-75. The intention is to discover what was new about the image for British women popular musicians that they constructed and the means by which they did so. The period studied was important for the convergence in Britain ofpop music with television and fashion. The thesis considers the women's role in this convergence in tenns both ofshaping and exploiting it The investigation was pursued through a range of primary source data, principally the viewing of the rare surviving recording of a programme from each of the four women's BBC television series. The use of the four programmes as case studies provides the main focus. Archival research using the two television listings publications of the period, the Radio Times and the TVTimes, provided the majority of the information locating the four programmes within the 1963-75 British television context; as well as demonstrating the way in which each was promoted for television and the range of television genres with which the four women were involved. Interviews with television cameramen associated with the programmes provided personal recollections uskd to complement and supplement the research. Popular music, television and fashion literature enabled the study of the interrelations between the three areas as evidenced in the four programmes. The findings demonstrate the active agency ofeach of the four women in the creation of her individual persona around which her eponymous BBC television series was constructed as a 'star vehicle', utilizing the convergence ofpop music, television and fashion. The findings reveal a fonnerly 'hidden history' of four British female pop music performers who brought their music perfonnance, with its key fashion component, to the pre-existing systems of British television light entertainment. In so doing each formulated for herself a new kind of career which transcended pop single achievement, at a particularly significant moment in time for British pop music, television and fashion. Dusty Springfield, CilIa Black, Sandie Shaw and Lulu, each in her own way changed, strengthened and enhanced the status of the British female pop perfonner according to the results of this research. The four women did so through fusing their awareness of British pop music and British fashion with an awareness of the audience for their British television performance. This thesis has thus investigated, evaluated and presented the evidence for this hitherto undocumented achievement.

description: The aim of this review was to describe and summarize the scientific literature on programming parameters related to jump or plyometric training in male and female soccer players of different ages and fitness levels. A literature search was conducted in the electronic databases PubMed, Web of Science and Scopus using keywords related to the main topic of this study (e.g., “ballistic” and “plyometric”). According to the PICOS framework, the population for the review was restricted to soccer players, involved in jump or plyometric training. Among 7556 identified studies, 90 were eligible for inclusion. Only 12 studies were found for females. Most studies (n = 52) were conducted with youth male players. Moreover, only 35 studies determined the effectiveness of a given jump training programming factor. Based on the limited available research, it seems that a dose of 7 weeks (1–2 sessions per week), with ~80 jumps (specific of combined types) per session, using near-maximal or maximal intensity, with adequate recovery between repetitions (<15 s), sets (≥30 s) and sessions (≥24–48 h), using progressive overload and taper strategies, using appropriate surfaces (e.g., grass), and applied in a well-rested state, when combined with other training methods, would increase the outcome of effective and safe plyometric-jump training interventions aimed at improving soccer players physical fitness. In conclusion, jump training is an effective and easy-to-administer training approach for youth, adult, male and female soccer players. However, optimal programming for plyometric-jump training in soccer is yet to be determined in future research.

description: The current study is one of the first to prospectively examine longitudinal associations between observed father caregiving behaviors and child cortisol reactivity and regulation in response to emotional arousal at 7 and 24 months of child age. Observations of father and mother caregiving behaviors and child cortisol levels in response to challenges at 7 months and 24 months were collected. Analyses were based on a subsample of children from the Family Life Project who lived with both their biological mothers and fathers and for whom there was at least partial cortisol data (7 months: n=717; 24 months n= 579). At 7 months of child age the sample was 49.0% female, 25.8% African American, and 74.2% European American. At 24 months of child age the sample was 49.9% female, 24.7% African American and 75.3% European American. Analyses across assessment points were conducted simultaneously using mixed linear modeling for repeated measures data to test for differential effects of fathering across infancy and toddlerhood. Concurrent measures of father negativity were positively associated with greater increases in child cortisol levels in response to emotion challenge at 7 months (p = .01) and with higher overall levels of cortisol at 24 months (p < .001). However, there was no evidence that father caregiving during infancy independently predicted later cortisol activity during toddlerhood.
title: Sustainable assumptions : modelling the ecological impacts of pre-pottery Neolithic farming communities in the Levant
Creators: name: Campbell, Dana
Publisher: name: University of Liverpool Repository
Year: 2023

description: During the Pre-Pottery Neolithic - Pottery Neolithic transition in the Levant, several centuries after the widespread adoption of agriculture and shortly after the adoption of mixed farming, a number of large, formerly successful communities seem to have been abandoned. These apparent settlement transformations are reported to have occurred alongside changes in technology and production, ideological behaviour and the treatment of the dead, and subsistence economy. Whether one views these purported changes as evidence of 'collapse' or not, particular transformations do seem to have taken place and require explanation. Several proposed models attempt to explain why these changes may have occurred, but the anthropogenically induced ecological degradation argument is the most pervasive. While this model has already been tested in a preliminary manner, detailed evaluation of the degradation argument partly based on agronomic research on the ecological impacts of mixed farming is still due.
title: Intracellular functions and interactions of age-related macular degeneration-associated variant B cystatin C.
Creators: name: Myerscough, Christopher
Publisher: name: University of Liverpool Repository
Year: 2015

description: Age related macular degeneration (AMD) is the leading cause of blindness among the elderly population. It occurs in two forms, a nonexudative "dry" form which can lead to geographic atrophy of the retinal pigment epithelial (RPE) cells in the region of the macula and an exudative "wet" form which involves neovascularisation from the choroid, through Bruch's membrane and the RPE layer and into the photoreceptor layer causing significant damage. Cystatin C is a cysteine protease inhibitor known to inhibit cathepsin activity. It is a highly abundant transcript in the RPE and is known to be processed through the secretory pathway . A variant form of this protein with an amino acid substitution in its signal sequence results in the protein being retained intracellularly and is found localised with the mitochondria. This variant form has been associated with increased risk of developing exudative AMD. In this study a number of key cellular processes were examined to elucidate the effect the variant B protein has on the RPE. These processes were respiration, apoptosis, autophagy and oxidative stress; all of which have been implicated in AMD pathology or ageing. In addition the protein-protein interactions of variant B cystatin C were assessed through mass spectrometry analysis of pulled-down cystatin C protein from transfected cell lysates. No effect on respiration, apoptosis or autophagy was identified. However a statistically significant difference in oxidative stress was identified as a result of overexpression of either wild type cystatin C or variant B cystatin C. Mass spectrometry analysis resulted in two highly promising proteins that were found interacting with variant B cystatin C at a statistically significant level, prohibitin and voltage-dependent anion-selective channel protein 1 (VDAC1). Although oxidative stress was found for both proteins given the nature of the expression (driven by a CMV promoter) it seems likely that the oxidative stress response is due to a high level of intracellular cystatin C. This suggests that the retention of variant B protein within the cell would lead to increased oxidative stress levels. It can be speculated that this response could be a contributory factor to development of AMD. VDAC1 and prohibitin may offer an explanation of what happens to the variant B protein within RPE cells. VDAC1 is the major pore-forming protein in the mitochondrial membrane, disruption of its functioning by the binding of variant B protein might be expected to have detrimental effects. Prohibitin is an even more promising target as it has been associated with oxidative stress. In addition it is known to translocate between the nucleus and the mitochondria, offering the tantalising possibility of a complete explanation for the mitochondrial mislocalisation.

description: We present a multi-wavelength analysis of star-forming galaxies in the massive cluster MS0451.6-0305 at z $\sim$ 0.54 to shed new light on the evolution of the far-infrared-radio relationship in distant rich clusters. We have derived total infrared luminosities for a spectroscopically confirmed sample of cluster and field galaxies through an empirical relation based on $Spitzer$ MIPS 24 $μ$m photometry. The radio flux densities were measured from deep Very Large Array 1.4 GHz radio continuum observations. We find the ratio of far-infrared to radio luminosity for galaxies in an intermediate redshift cluster to be $q_{\rm FIR}$ = 1.80$\pm$0.15 with a dispersion of 0.53. Due to the large intrinsic dispersion, we do not find any observable change in this value with either redshift or environment. However, a higher percentage of galaxies in this cluster show an excess in their radio fluxes when compared to low redshift clusters ($27^{+23}_{-13}\%$ to $11\%$), suggestive of a cluster enhancement of radio-excess sources at this earlier epoch. In addition, the far-infrared-radio relationship for blue galaxies, where $q_{\rm FIR}$ = 2.01$\pm$0.14 with a dispersion of 0.35, is consistent with the predicted value from the field relationship, although these results are based on a sample from a single cluster.

description: This study examined friendship selection and socialization as mechanisms explaining similarity in depressive symptoms in adolescent same-gender best friend dyads. The sample consisted of 1,752 adolescents (51% male) ages 12–16 years (M = 13.77, SD = 0.73) forming 487 friend dyads and 389 nonfriend dyads (the nonfriend dyads served as a comparison group). To test our hypothesis, we applied a multigroup actor–partner interdependence model to 3 friendship types that started and ended at different time points during the 2 waves of data collection. Results showed that adolescents reported levels of depressive symptoms at follow-up that were similar to those of their best friends. Socialization processes explained the increase in similarity exclusively in female dyads, whereas no evidence for friendship selection emerged for either male or female dyads. Additional analyses revealed that similarity between friends was particularly evident in the actual best friend dyads (i.e., true best friends), in which evidence for socialization processes emerged for both female and male friend dyads. Findings highlight the importance of examining friendship relations as a potential context for the development of depressive symptoms.

description: Few thinkers familiar with D.Z. Phillips' philosophy of religion would deny that his approach is problematic. What is not often acknowledged however is that it has also been widely misrepresented. The aim of this thesis is to clarify his views where they have been most misunderstood, to identify areas of weakness, and to emphasise the strength of his approach within the philosophy of religion. Much of the thesis concerns the controversies surrounding his adoption of certain terms and phrases from Wittgenstein's philosophical method, and his application'of these within his philosophy of religion.

title: Functionalised dipeptides as hydrogelators for energy transfer and as drug delivery vehicles
Creators: name: Awhida, Salmah
Publisher: name: University of Liverpool Repository
Year: 2015

description: This thesis will cover aspects of functionalised dipeptide hydrogels and their application in energy transfer and as vehicles for drug delivery. In the first section, a large number of dipeptides conjugated to different aromatic groups were synthesised. We synthesised 35 dipeptides conjugated to different aromatic groups (naphthalene, anthracene, phenanthrol, anthraquinone, carbazole and pyrene). We synthesised a large number of dipeptides with different hydrophobicity and different aromatic groups in order to study their ability to form gels and study the mechanical properties of the gels. The second part of this thesis will investigate the formation of hydrogels based on dipeptides with different aromatic groups. The focus in this section was on the gelation as well as the effect of changing the solvent and changing the amino acids used. This section then explores the properties of the resulting hydrogels. A number of different dipeptides containing different amino acids were tested, some of which formed gels and others. The dipeptides also had different pKa values. This factor was shown to be important in driving the preferential selection of a certain amino acids. The thesis then describes energy transfer which can occur between two dipeptides (pyrene and anthracene dipeptides), or between a dipeptide and a dansyl derivative (phenanthrol and dansyl, or carbazole and dansyl). These results showed that energy transfers can occur in these specific hydrogels. In all other cases, no evidence for energy transfer was found. This may imply that the packing of the fibres is important for energy transfer and this should be the focus of future work. The final section of this thesis describes the controlled release of model dyes from these gels. We studied controlled release from FmocFF hydrogels and from one other functionalised dipeptide hydrogel at different gelator concentrations and at different pH. The release of the dye from the hydrogel can be controlled by different factors, including the pH, peptide concentration, the microstructure and the mesh size. Furthermore, choosing the right method to prepare hydrogel allows us to control the microstructure for hydrogel to be injectable. Therefore, by controlling these entire factors we can use these kinds of hydrogels for drug delivery applications.

description: To make relevant predictions about observable emission, hydrodynamical simulation codes must employ schemes that account for radiative losses, but the large dimensionality of accurate radiative transfer schemes is often prohibitive. Stamatellos and collaborators introduced a scheme for smoothed particle hydrodynamics (SPH) simulations based on the notion of polytropic pseudo-clouds that uses only local quantities to estimate cooling rates. The computational approach is extremely efficient and works well in cases close to spherical symmetry, such as in star formation problems. Unfortunately, the method, which takes the local gravitational potential as an input, can be inaccurate when applied to non-spherical configurations, limiting its usefulness when studying disks or stellar collisions, among other situations of interest. Here, we introduce the "pressure scale height method," which incorporates the fluid pressure scale height into the determination of column densities and cooling rates, and show that it produces more accurate results across a wide range of physical scenarios while retaining the computational efficiency of the original method. The tested models include spherical polytropes as well as disks with specified density and temperature profiles. We focus on applying our techniques within an SPH code, although our method can be implemented within any particle-based Lagrangian or grid-based Eulerian hydrodynamic scheme. Our new method may be applied in a broad range of situations, including within the realm of stellar interactions, collisions, and mergers.

title: Molecular ecology of anaerobic cellulose-degrading microorganisms in landfill sites
Creators: name: Edward McDonald, James

description: Landfill sites are anoxic environments in which the conversion of organic polymers to methane is mediated by a consortium of microorganisms representing several different trophic groups. Cellulose is the most abundant biodegradable organic polymer in landfill sites, and its hydrolysis represents the initial stage of landfill waste stablistation. It has been suggested that four phylogenetic clusters of the bacterial genus Clostridium that contain cellulolytic species (clusters I, III, IV and XIVab) are the predominant cellulose-degraders in landfill environments.
Susceptibility to peer influence: Using a performance-based measure to identify adolescent males at heightened risk for deviant peer socialization.

description: A substantial amount of research has suggested that adolescents’ attitudes and behaviors are influenced by peers; however, little is known regarding adolescents’ individual variability, or susceptibility, to peer influence. In this study, a performance-based index from an experimental paradigm was used to directly measure adolescents’ susceptibility to peers. A total of 36 adolescent boys participated in a “chat room” experiment in which they ostensibly were exposed to deviant or risky social norms communicated either by high-peer-status (i.e., popular, well-liked) or low-peer-status (i.e., unpopular, disliked) grade mates who actually were electronic confederates. Changes in adolescents’ responses before and after exposure to peer norms were used as a measure of peer influence susceptibility. These same adolescents completed a questionnaire assessment at the study outset and again 18 months later to assess their actual engagement in deviant behavior and their perceptions of their best friend’s engagement in deviant behavior. Only among adolescents with high levels of susceptibility to high-status peers was a significant longitudinal association revealed between their best friend’s baseline deviant behavior and adolescents’ own deviant behavior 18 months later. Findings support the predictive validity of a performance-based susceptibility measure and suggest that adolescents’ peer influence susceptibility may generalize across peer contexts.
Young adult identities and their pathways: A developmental and life course model.

description: Developmental and life course studies of young adult identities have focused on two dimensions, subjective age and psychosocial maturity. This study examines the developmental synchrony of these two processes. In a longitudinal sample of young adults from Add Health (18 to 22), a person-centered analysis of indicators of these dimensions identified four identity profiles. Two depict early and late patterns of identity; the others represent contrasting types of discordance, “pseudo-adult”, subjective age more advanced than maturation level and “anticipatory”, with subjective age less advanced than maturational level. The profiles vary by gender, socioeconomic status, and race-ethnicity as well as by adolescent (ages12–16) pubertal maturation, psychosocial adjustment, and family context. These results provide support for a more holistic, interdisciplinary understanding of adult identity, and show that young adult identities in the Add Health sample follow differentiated paths into the adult years, with largely unknown consequences for the subsequent life course.

description: Adult (age 30) educational, economic, and social-emotional adjustment outcomes were investigated for participants in the Abecedarian Project, a randomized controlled trial of early childhood education for children from low-income families. Of the original 111 infants enrolled (98% African American), 101 took part in the age-30 follow-up. Primary indicators of educational level, economic status, and social-adjustment were examined as a function of early childhood treatment. Treated individuals attained significantly more years of education, but income-to-needs ratios and criminal involvement did not vary significantly as a function of early treatment. A number of other indicators were described for each domain. Overall, the findings provide strong evidence for educational benefits, mixed evidence for economic benefits and little evidence for social-adjustment outcomes. Implications for public policy are discussed.
