In the context of growing concerns about the mental health of children and adolescents in the United Kingdom, it is recognised that social support offered by parents, peers and teachers plays an important role in the emotional and psychological well-being of young people. This thesis (Volume One) was produced as part of the written requirements for the Doctoral training in Educational Psychology. It contains four chapters. Chapter One provides an overview of the volume of work and foregrounds my identity and epistemological position. Chapter Two provides a critical review of the theoretical and research literature on social support for children and young people. Chapter Three reports on findings from a small-scale study carried out with adolescent girls within a friendship group at a secondary school. The research employed qualitative methods to explore participants’ lived experience of social support, and data were analysed using Interpretative Phenomenological Analysis (IPA). Chapter Four comprises final reflections on IPA as a methodology and the contribution of the study to my practice as an educational psychologist (EP).

Groundwater dynamics in beaches have been investigated through field and laboratory experiments. The observations have been used to test the ability of currently available mathematical and numerical models to adequately account for the influence of processes such as vertical flow and capillarity. New 1D sand column experiments have been conducted to examine the influence of a truncated capillary fringe on periodic water table oscillations. As the fringe becomes increasingly truncated the aquifer storage term, the complex effective porosity n ω, is substantially reduced in agreement with previous findings under steady flow conditions. The findings are a useful starting point for an investigation of the dynamics of the water table exit point in beaches where the water table lies just below the sand surface. A simple 2D laboratory aquifer, influenced by finite-depth and capillarity effects, subject to simple harmonic periodic forcing has been used to investigate the dispersion of the water table waves. The performance of existing dispersion relation theories, accounting for both capillarity and finite-depth effects, deteriorates at higher oscillation frequencies suggesting that other, neglected processes have some influence. Horizontal flow in the capillary fringe is suggested as such a process. The generation of higher harmonics due to a sloping beach face is also investigated in the laboratory. The observations reveal that the generation process is strongest near the sand surface, likely to be due to vertical flows into the aquifer being strongest near the sand surface. A 2DV numerical model is applied to the data and does well in predicting the nature of the generation process, qualitatively reproducing the variation in oscillation amplitude with depth in the inter-tidal zone. Application of a modified Boussinesq equation to estimate aquifer recharge due to infiltration from wave runup is critically applied to field and laboratory measurements. Finite amounts of flux across the water table are seen at, and landward of, the runup limit where there is zero infiltration at the sand surface. This suggests that the capillary fringe and vertical flows in this region are significant and that application of the model be undertaken with care. Field observations of the salinity structure and its response to ocean forcing reveal no response to tidal forcing but a significant response to a wave-induced pulse in groundwater levels. The infiltration of salty ocean water due to infiltration from wave runup is shown to reverse the traditional “salt-wedge” scenario in the surficial aquifer with a thin salty layer overlying the fresh water.

Phospholipase A2 (PLA2) extensively exists in various snake venom. Till now, a controversy remained to elucidate whether the PLA2 activity exclusively associates with the manifestation of the pharmacological activities. In the present study, we used liposome to imitate cell membrane for excluding the effects of receptor and membrane proteins, and estimating the molecular mechanism of snake venom phospholipase A2 on damaging liposome. Although a greater membrane damaging activity of Naja naja atra phospholipase A2 (NNA-PLA2) and notexin was noted in the presence of Ca2+, inhibitions of PLA2 activity by Sr2+ and Ba+2 were unable to abolish the membrane damaging effect. In addition, modification of Lys-82 and Lys-115 of notexin retained the full PLA2 activity, but the membrane damaging activity notably decreased. Fluorescence quenching studies, CD measurement, and tryptophan fluorescence lifetime assay indicated that liposome induced the £\-helix conformation change and the tryptophan residues microenviroment change with the addition of Ca2+, Sr2+ or EDTA. Rhodamine quenching assay revealed that NNA-PLA2 and notexin formed oligomers when they bound with liposome. Besides, the modified PLA2 (BPB-PLA2) only formed monomer when it bound with liposome and lost the membrane damaging activity. Taken together, these results indicate that the membrane damaging effects of NNA-PLA2 and notexin are not critically caused by their enzymatic activitys and are probably associated with oligomerization.

Il lavoro affronta la problematica dei sistemi di copertura in messapia in età arcaica. Dopo una preliminare storia della ricerca nel settore ed un inquadramento metodologico dello studio si analizzano i materiali di copertura di s. Vito dei Normanni (BR) e di Cavallino (LE). Le recenti indagini archeologiche nei due siti hanno offerto nuovi dati sull'architettura ed il modo di abitare in età arcaica. A Cavallino è stato individuato un sistema di copertura sul modello laconico con l'impiego di soli coppi disposti alternativamente. A s. Vito dei Normanni la copertura degli edifici è più complessa. I tetti disponevano di tegole piatte con alette laterali rialzate e coppi utilizzati come coprigiunti tra le commettiture. In questo sito, lo studio analitico dei crolli durante lo scavo archeologico ha permesso di ricostruire la tecnica costruttiva dell'alzato ed i materiali impiegati. E' stato possibile individuare anche una prima forma di decorazione architettonica. I dati archeologici hanno consentito l'elaborazione di una ricostruzione grafica del grande edificio di s. Vito dei Normanni. Il lavoro è completato da un'appendice sull'architettura rurale salentina, valido modello di confronto per lo studio delle soluzioni architettoniche. Un paragrafo affronta il problema delle incisioni su tegole e coppi chiarendo come spesso si tratti di semplici marche da montaggio. / Analysis of roofs in messapia in archaic period. after a preliminary history of researches in the field and of methodology's discussion, the author examines the architectural material from san vito dei normanni (Br) and Cavallino (LE).

Paolo, Mosè e l'Alleanza non revocata in 2 Cor 3,1-4,6 La pericope di 2 Cor 3,1-4,6 appartiene a uno scritto denso e problematico. Nel quadro più ampio del confronto con gli “oppositori”, il testo esaminato dimostra la fedeltà di Paolo alle sue radici, che sono fondate nell'Israele della promessa e della berît stabilita per sempre, “nuova” perché rinnovata e alla quale è stato tolto il velo che copriva il volto di Mosè. Dimostra anche il suo ininterrotto dialogare con la Scrittura. L'Apostolo riconosce nel volto del Cristo - quel volto che ha trasfigurato la sua vita e lo ha definitivamente conquistato - la vera immagine di Dio. Al Figlio di Dio crocifisso e risorto Paolo ha affidato la sua causa: la sua parrhs…a non è soffocata dalle tribolazioni che sembrano minacciare la sua stessa vita. Proprio nelle sofferenze con le quali segue la crescita dell'™kklhs…a, l'Apostolo realizza la configurazione a Colui che gli si è manifestato e al suo eÙaggšlion. Il linguaggio di questi versetti riflette il vissuto dinamico della giovane chiesa di Corinto, chiamata a proteggere la koinwn…a e a rafforzarsi nell'¢g£ph, senza lasciarsi avvincere dalle lusinghe di chi intende separarla dal suo ministro (di£konoj-doàloj), Paolo. / Paul, Moses and the non-revoked Covenant in 2 Cor 3,1-4,6 The pericope of 2 Cor 3,1-4,6 belongs to a dense and perplexing writing. In the wider frame of the confrontation with the “opponents”, the text examined shows Paul's faithfulness to his roots, which are put down in the Israel of the promise and of the berît settled forever, which is “new” because renewed and set free from the veil which covered Moses' face. It also shows Paul's uninterrupted dialogue with Scripture. The Apostle recognizes in Christ's face - the face that transfigured his life and definitively gained him - God's true image. Paul has relied on the crucified and risen Son of God; so his parrhs…a is not stifled by the tribulations that seem to threaten his own life. Right in the sufferings in which he follows the growing of the ™kklhs…a, the Apostle assumes the shape of Who that revealed himself to him and of his eÙaggšlion. The language of these verses mirrors the dynamic background of the Corinthian church, called to shield the koinwn…a and to get stronger in the ¢g£ph, without being won over by the flattery of those who try to divide her from her minister (di£konoj-doàloj), Paul.
