description: A three-dimensional approach based on momentum vectors as variables for solving the three nucleon Faddeev equation in first order is presented. The nucleon-deuteron break-up amplitude is evaluated in leading order in the NN T-matrix, which is also generated directly in three dimensions avoiding a summation of partial wave contributions. A comparison of semi-exclusive observables in the $d(p,n)pp$ reaction calculated in this scheme with those generated by a traditional partial wave expansion shows perfect agreement at lower energies. At about 200 MeV nucleon laboratory energies deviations in the peak of the cross section appear, which may indicate that special care is required in a partial wave approach for energies at and higher than 200 MeV. The role of higher order rescattering processes beyond the leading order in the NN T-matrix is investigated with the result, that at 200 MeV rescattering still provides important contributions to the cross section and certain spin observables. The influence of a relativistic treatment of the kinematics is investigated. It is found that relativistic effects become important at projectile energies higher than 200 MeV.

description: Root and shoot development of Dracaena fragrans 'Massangeana' was determined 51, 72, 93, and 114 days after fresh cut cane was planted. Basal circumference of canes varied from 13.5 to 19.5cm. At each sampling date, root:shoot ratio was affected by cane circumference. As cane circumference increased above 14.5cm, root length and root:shoot ratio decreased. Number of developing shoots was not affected by cane circumference at any sampling date. Leaf area was not affected until sampling day 114, when it increased as circumference increased. ----- Se evaluaron los efectos de seis tratarnientos sobre el desarrollo radicular en canas de Oreceene fragrans "Massangeana", Los tratamientos fueron: (a) aniIIado a 12cm. de Ia base de la catta, (b) anillados a 6 y I2cm. de la base de la cai{a, (c) muescado usando un grupo de tres pequenos incisiones horizontales a I2cm. de la base de la cana, (d) muescado unsando dos grupos de tres pequenos incisiones horizontales a 6 y 12cm. de las base de la caii'a, (e) cortes longitudinales utilizando tres incisiones de 12cm. de largo distribuidas cada 120 ualrededor de la caiia y, (f) control. Aunque el desarrollo radicular fue afectado por los diferentes tratamientos, la circunferencia de las caffas tambien ejercid' una fuerte influencia. Las canas con las mayores y menores circunferencias desarrollaron un sistema radicular menos extenso que aquellas de tamaiio medio, mientras que el optimo desarrollo foliar ocurrio' en aquellas caiias de circunferencia mayor.

description: The pivotal role that glycosylation plays in cell signaling to disease processes in particular, has led to increasing interest in glycation site identification. Current "bottom-up" proteomic methods are complex and time-consuming, requiring a combination of affinity and reverse-phase chromatography prior to mass spectrometry. Moreover, it is difficult to optimize or compare these methods because a set of appropriate glycopeptide standards is not commercially available, nor is it practical to synthesize a set. Here we utilize electrostatic repulsion-hydrophilic interaction chromatography (ERLIC) to isolate glycopeptides selectively from a source in vivo: A tryptic digest of bovine fetuin. We have identified eight of the eleven published peptide sequence/glycan compositions, with the addition of five novel combinations . From these, a set of glycopeptide standards has been selected for use in the development of chromatographic methods that will reliably retain and deliver all glycopeptides in a digest.

description: We use inelastic neutron scattering and molecular dynamics simulation to investigate the interplay between the structure and the fast sodium ion diffusion in various sodium silicates. With increasing temperature and decreasing density the structure factors exhibit an emerging prepeak around 0.9 A^-1. We show, that this prepeak has its origin in the formation of sodium rich channels in the static structure. The channels serve as preferential ion conducting pathways in the relative immobile Si-O matrix. On cooling below the glass transition this intermediate range order is frozen in.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

title: The impact of childhood sexual interaction on current psychological functioning in a male forensic population
Creators: name: Rees, Neil David
Publisher: name: The Open University
Year: 1998

description: Little research attention has been paid to forensic populations of male survivors of childhood sexual abuse (CSA), where it is understood that prevalence rates are high. This study aimed to survey a sample of 40 men in a maximum security hospital who had experienced childhood sexual interaction (CSI). The study profiled the psychological functioning of the sample through a number of standardised measures and a semi-structured interview. In addition, the meanings that the men attached to their childhood sexual experiences,t heir 'constructions' of them, were also examined, along with their self-report of distress related to these experiences. The limited research conducted with male survivors suggests that men tend to construct CSI in more positive or neutral terms than female survivors, and are less likely to report distress related to the experience. However, men's experiences of CSI have still shown similar levels of association with psychological symptomatology in adulthood. This apparent discrepancy has been understood in terms of male socialisation. The predictions that the men in this sample would show high levels of psychological symptomatology, which would be associated with the characteristics of CSI, and that the majority of them would describe positive or neutral constructions of CSI, and would tend to report no distress related to their experiences, were supported in this study. The implications of these findings are discussed. Overall, it is stressed that in order to fully understand the impact of CSA on males, and to provide appropriate approaches to interventions, a fuller appreciation of the role of male socialisation must be achieved.

description: We present models for the three-point correlation function (3PCF) of both dark matter and galaxies. We show that models based on the halo model can reasonably match the dark matter 3PCF obtained from high-resolution $N$-body simulations. On small scales ($r\la 0.5\mpch$) the 3PCF is sensitive to details regarding the density distributions of dark matter haloes. On larger scales ($r \ga 2.0\mpch$) the results are very sensitive to the abundance of the few most prominant haloes. Using the conditional luminosity function, we also construct models for the 3PCF of galaxies, which we test against large mock galaxy samples. The bias of the galaxy distrubution with respect to the dark matter, and the finite number of galaxies that can be hosted by individual haloes, significantly reduce the normalized three-point correlation function with respect to that of dark matter. Contrary to the 3PCF of the dark matter, the galaxy 3PCF is much less sensitive to details regarding the spatial number density distribution of galaxies in individual haloes or to the abundance of the few most massive systems. Finally, we show that our model based on the conditional luminosity function is in good agreement with results obtained from the 2-degree Field Galaxy Redshift Survey. In particular, the model nicely reproduces the observational finding that the 3PCF for early-type galaxies is slightly higher than that of late-type galaxies, and that there is no significant dependence of the 3PCF on galaxy luminosity.

description: Standardized criteria are needed to select seedlings of mango (Mangifera indica L.) that merit retention in a varietal improvement program, and to compare selections and cultivars evaluated. Such a slate lets seedlings and new or uncommon cultivars be compared with well-known standards. Preferences may vary in different regions, and performance of a given cultivar may vary; however, application of this system or clearly defined modifications of it can enhance the interchange of information and plant material worldwide among people working to improve mangos. Traits of importance arc shape, size, colour, firmness, fiber content, disease resistance, flavor, and productivity. A tabular system for rating these characters like those already used for strawberry and blueberry was developed and is being used to advantage in a program of mango germplasm evaluation. Occasional defects such as fruit cracking, "jelly seed" or stem end breakdown are noted when necessary in a "Remarks" column. A "Score" column permits one or more checks to give an estimate of overall quality, and a tree slated for discard is also designated here by a special sign, "[x]". ----- Seprecisan criterios para seleccionar plantas de mango (Mangifera indica L.) de semillero que merecen retenciJ'n en programas de mejoramiento, y para comparar selecciones y variedades ya evaluados, Tal sistema per mite la comparacid" n de plantas de semillero y nuevas variedades con variedades establecidas.

The host galaxy/AGN connection in nearby early-type galaxies. Sample selection and hosts brightness profiles

description: This is the first of a series of three papers exploring the connection between the multiwavelength properties of AGNs in nearby early-type galaxies and the characteristics of their hosts. We selected two samples, both with high resolution 5 GHz VLA observations available and providing measurements down to 1 mJy level, reaching radio-luminosities as low as 10^19 W/Hz. We focus on the 116 radio-detected galaxies as to boost the fraction of AGN with respect to a purely optically selected sample. Here we present the analysis of the optical brightness profiles based on archival HST images, available for 65 objects. We separate early-type galaxies on the basis of the slope of their nuclear brightness profiles, into core and power-law galaxies following the Nuker's scheme, rather than on the traditional morphological classification (i.e. into E and S0 galaxies). Our sample of AGN candidates is indistinguishable, when their brightness profiles are concerned, from galaxies of similar optical luminosity but hosting weaker (or no) radio-sources. We confirm previous findings that relatively bright radio-sources (L_r > 10^(21.5) W/Hz) are uniquely associated to core galaxies. However, below this threshold in radio-luminosity core and power-law galaxies coexist and they do not show any apparent difference in their radio-properties. Not surprisingly, since our sample is deliberately biased to favour the inclusion of active galaxies, we found a higher fraction of optically nucleated galaxies. Addressing the multiwavelength properties of these nuclei will be the aim of the two forthcoming papers.

Almost two centuries later, the quest to formulate a quantum theory of the thermodynamic laws has thus unsurprisingly motivated physicists to visualise what are known as `quantum thermal machines' (QTMs). In this article, we review the prominent developments achieved in the theoretical construction as well as understanding of QTMs, beginning from the formulation of their earliest prototypes to recent models. We also present a detailed introduction and highlight recent progress in the rapidly developing field of `quantum batteries'.

description: The effects of growth regulator treatments on flowering pattern, flower suppression and fruit set in mature mango trees were examined. Gibberellic acid (100 ppm) suppressed flowering for six weeks, this response being delayed in one trial. Potassium nitrate (20,000 ppm) greatly increased flowering whereas Ethrel (ethephon) at 2000 ppm was not as successful. Planofix (I-naphthylacetic acid, sodium salt) at 20 ppm appeared to increase initial fruit set when applied to inflorescences but this effect was not sustained in the trial. Planofix applied to fruit (l-2cm diameter) caused an 18% reduction in fruit drop which doubled final fruit yield. ----- Se exam ina los efectos de los tratamientos con reguladores de crecimiento en el patron de floraci6n, la supresion de flores y el cuajado de frutos en los arboles maduros de mango.

A distributed snapshot protocol for virtual machines

description: The distributed snapshot protocol is a critical technology in the areas of disaster recovery and computer security of distributed systems, and there have appeared a huge number of projects working on this topic since the 1970's. Recently, with the popularity of parallel computing and disaster recovery, this topic has received more and more attention from both academic and industrial researchers. However, all the existing protocols have several common disadvantages. First, existing protocols all require several modifications to the target processes or their OS, which is usually error prone and sometimes impractical. Second, all the existing protocols are only aiming at taking snapshots of processes, not whole entire OS images, which constrains the areas to which they can be applied. This thesis introduces the design and implementation of our hypervisor level, coordinated non-blocking distributed snapshot protocol. Superior to all the existing protocols, it provides a simpler and totally transparent snapshot platform to both the target processes and their OS images. Based on several observations of the target environment, we simplify our protocol by intentionally ignoring the channel states, and to hide our protocol from the target processes and their OS, we, on one hand, exploit VM technology to silently insert our protocol under the target OS, and on the other hand, design and implement two kernel modules and a management daemon system in the control domain. We test our protocol with several popular benchmarks and all the experimental results prove the correctness and the efficiency of our protocol.
title: Modelling fruit and vegetable consumption : a comparative study of two cities with high and low consumption
Creators: name: Piacentini, Maria Grazia
Publisher: name: The Open University
Year: 1998

description: The importance of the consumption of a diet rich in fruit and vegetables, for overall health, has been highlighted by the UK government in recent years. Consumption of fruit and vegetables is considerably lower in Scotland than in other parts of the UK. Behavioural change is most likely to come about through a comprehensive understanding of the range of factors influencing fruit and vegetable consumption, and the nature of the interaction of these factors. With variations in fruit and vegetable consumption by place and social class, this study focused on an area of low fruit and vegetable consumption in Scotland, and compared this to an area of high fruit and vegetable consumption in England, with socio-economic profile matched. The determinants of consumption, and their interrelationship, were investigated using qualitative information from focus group discussions, and quantitative data from a structured questionnaire. Multivariate models of fruit and vegetables consumption were developed, using log linear analysis, logistic regression and discriminant analysis. The models developed identified significant differences between fruit and vegetable consumption behaviour. Fruit consumption was mainly influenced by sociodemographic variables,in particulars mokers tatus. The impact of place and social class was substantial, when these variables were considered in interaction with the other socio-demographic variables. In contrast, vegetable consumption was influenced by motivational and attitudinal factors. Of these, the extent to which vegetables satisfied `convenience' expectations, and `hedonic motivations' were the most important influences, critical to vegetable consumption. The findings also suggest that the development of a generic model of food choice may not be an achievable goal, since the models of these two (similar) foodstuffs are so different. Strategies to promote fruit and vegetable consumption, must address the different characteristics, and priorities, of low fruit and vegetable consumers.

Semiclassical methods of theory of complex trajectories have been applied to nuclear tunneling, and conditions for the effects have been obtained. We demonstrate the enhancement of alpha particle decay by incident proton with energy of about 0.25 MeV. We show that the general features of this process are common for other sub-barrier nuclear processes and can be applied to nuclear fission.

description: Photons carrying orbital angular momentum (OAM) are excellent qudits and are widely used in several applications, such as long distance quantum communication, $d$-dimensional teleportation and high-resolution imaging and metrology. All these protocols rely on quantum tomography to characterise the OAM state, which currently requires complex measurements involving spatial light modulators and mode filters. To simplify the measurement and characterisation of OAM states, here we apply a recent tomography protocol [Asadian et al., \pra {\bf 94}, 010301 (2016)]. Our scheme for OAM tomography in $d$ dimensions requires only a set of measurements on a mode qubit, i.e., a 2-dimensional system. This replaces the current complexity of OAM measurements by the ability to perform generalized Pauli operators $X_d, Z_d$ on OAM states. Our scheme can be adapted in principle to other degrees of freedom, thus opening the way for more complex qudit tomography.

description: During the 1930's numerous atemoya seedlings appeared in Isreal. At that period Annona seedlings were used for planting and seeds were often obtained from fruit tree collections where A. cherimola and A. squamosa were planted in close proximity. Both species have protogyneous flowers; however they differ greatly in their flowering pattern. A. cherimola flowers open in the morning, are fully receptive for about 24 hr and shed their pollen in the afternoon. A. squamosa (one tree and its offspring) flowers open during the day and shed their pollen around 2 a.~. During the fir~t p~rt of A. cherimola flowering season flowers were found to open only on alternate days, with full synchronization on all trees. These flowering patterns tend to promote cross pollination between A. cherimola and A. squamosa. ----- Durante los a[(os treinta, mucha plantas de semillero aparecieron en Israel. En aquel entonces, se utilizaba las plantas de semillero de Anona para la plataci6'n y se obtenla frecuentemente las semillas en huertos donde se habra plantado la A. cherimola y la A. squamosa a poca distancia entre los arboles. Ambas especies tienen flores protogineas; sin embargo, tienen patrones de floraci6n muy diferentes, Las flores de la A. cherimola se abren por la maifana, son plenamente receptivas durante unas 24 horas y despues dejan caer su polen por fa tarde. Las flores de la A. squamosa (un ~bol y su progenie) se abren durante el dill y dejan caer su polen a eso de las dos de la tarde. Se note que, durante la primnera parte de la florescencia de la A. cherimole, las flores sOlo se abrtan cada tercer d(a, con plena simcronizacidn entre todos los arboles. Estos patrones de floracion tienden a favorecer la polinizacion cruzada entre la A. cherimols y la A. squemose.

Effects of selected ligands on U (VI) immobilization by zerovalent iron

Year: 2006

description: The effect of Cl-, CO32-, EDTA, NO2-, NO3-, PO43-, SO42-, and humic substances (HS)on the U(VI)co-precipitation from aqueous solutions by zerovalent iron (ZVI) was investigated in the neutral pH range.Batch experiments without shaking were conducted for 14 days mostly with five different ZVI materials (15 g/l), selected ligands (10mM) and an U(VI) solution (20 mg/l, 0.084mM). Apart from Cl-, all tested ligands induced a decrease ofU(VI)coprecipitation. This decrease is attributed to the surface adsorption and complexation of the ligands at the reactive sites on the surface of ZVI and their corrosion products. The decrease ofU(VI)removal was not uniform with the five ZVI materials. Generally, groundwater with elevated EDTA concentration could not be remediated with the ZVI barrier technology. The response of the system on the pre-treating by two ZVI materials in 250mM HCl indicated that in situ generated corrosion products favor an irreversible U(VI) uptake. Thus for the long term performance of ZVI barrier, the iron dissolution should continue in such a way that fresh iron oxide be always available for U(VI) coprecipitation.

description: Wheat growers' choice of production practices and geographic location were the major determinants of their costs of production, according to the findings of a 1994 survey conducted by the U.S. Department of Agriculture. One-fourth of surveyed farms reported using some form of conservation tillage, especially farms in the North Central, Northern Plains, and Southeast regions. On a per-bushel basis, low-cost farms tended to be small in terms of wheat acreage and total farm acreage. Differences in capitalization, tenure, and the use of custom services accounted for nearly 81 percent of the variation in the cost of producing wheat. Most size economies were realized at around 200 to 300 wheat acres.

description: We present an extensive study of magnetic fields in a system of merging galaxies. We obtained for NGC4038/39 (the Antennae) radio total intensity and polarization maps at 8.44, 4.86 and 1.49GHz using the VLA in the C and D configurations. The radio thermal fraction was found to be about 50% at 10.45GHz, higher than in normal spirals. The mean total magnetic fields in both galaxies are about two times stronger (20microG) than in normal spirals. However,the degree of field regularity is rather low, implying tangling of the regular component in regions with interaction-enhanced star formation. Our data combined with those in HI, Halpha, X-rays and in far infrared allow us to study local interrelations between different gas phases and magnetic fields. We distinguish several radio-emitting regions with different physical properties and at various evolutionary stages. The whole overlapping region shows a coherent magnetic field structure, probably tracing the line of collision between the arms of merging spirals while the total radio emission reveals hidden star formation nests. The southern part of it is a particularly intense merger-triggered starburst. Highly tangled magnetic fields reach there strengths of 30microG, even larger than in both individual galaxies, possibly due to compression of the original fields pulled out from the parent disks. In the northeastern ridge, away from star-forming regions, the magnetic field is highly coherent with a strong regular component of 10microG tracing gas shearing motions along the tidal tail. Modelling Faraday rotation data show that we deal with a three-dimensionally curved structure of magnetic fields, becoming almost parallel to the sky plane in the southeastern part of the ridge.

description: Purpose: To design multi-disease classifiers for body CT scans for three different organ systems using automatically extracted labels from radiology text reports.Materials & Methods: This retrospective study included a total of 12,092 patients (mean age 57 +- 18; 6,172 women) for model development and testing (from 2012-2017). Rule-based algorithms were used to extract 19,225 disease labels from 13,667 body CT scans from 12,092 patients. Using a three-dimensional DenseVNet, three organ systems were segmented: lungs and pleura; liver and gallbladder; and kidneys and ureters. For each organ, a three-dimensional convolutional neural network classified no apparent disease versus four common diseases for a total of 15 different labels across all three models. Testing was performed on a subset of 2,158 CT volumes relative to 2,875 manually derived reference labels from 2133 patients (mean age 58 +- 18;1079 women). Performance was reported as receiver operating characteristic area under the curve (AUC) with 95% confidence intervals by the DeLong method. Results: Manual validation of the extracted labels confirmed 91% to 99% accuracy across the 15 different labels. AUCs for lungs and pleura labels were: atelectasis 0.77 (95% CI: 0.74, 0.81), nodule 0.65 (0.61, 0.69), emphysema 0.89 (0.86, 0.92), effusion 0.97 (0.96, 0.98), and no apparent disease 0.89 (0.87, 0.91). AUCs for liver and gallbladder were: hepatobiliary calcification 0.62 (95% CI: 0.56, 0.67), lesion 0.73 (0.69, 0.77), dilation 0.87 (0.84, 0.90), fatty 0.89 (0.86, 0.92), and no apparent disease 0.82 (0.78, 0.85). AUCs for kidneys and ureters were: stone 0.83 (95% CI: 0.79, 0.87), atrophy 0.92 (0.89, 0.94), lesion 0.68 (0.64, 0.72), cyst 0.70 (0.66, 0.73), and no apparent disease 0.79 (0.75, 0.83). Conclusion: Weakly-supervised deep learning models were able to classify diverse diseases in multiple organ systems.

title: Causal attributions in schizophrenia: an investigation of clients and relatives causal attributions about the illness. This would be examined in relation to clients perceptions of family relationships, knowledge about schizophrenia and family distress
Creators: name: Richards, Marina Gail Anne
Publisher: name: The Open University
Year: 1998

description: Many clients with severe mental health problem, live in the community with their relatives. Research in the area has indicated that exacerbation of psychotic symptoms in clients is strongly associated with the emotional atmosphere in the family. The presence of high expressed emotion has been linked with relapse. However, recent research suggests that it is the causal attributions which relatives make to explain the illness symptomatology, which is most predictive of relapse. Relatives viewing clients' symptoms as being controllable by the client has been associated with hostility in relatives. Little has been said in the literature about the subjective experiences of clients. The present study investigated the causal attributions which clients and relatives made to explain the manifestation of the illness. Causal attributions made to explain positive symptoms, negative symptoms and behavioural problems were examined and compared. Clients! perception of their relationship with a key relative and their affective state was measured. Participants knowledge about schizophrenia, and relatives levels of distress were also examined. The clients in the present study were men under fifty with a diagnosis of schizophrenia. Key relatives also participated. A cross sectional correlational and comparative methodology was employed. A mixture of quantitative data and qualitative information was generated. A key finding was that the nature of attributions made was determined by symptom category. Positive Symptoms were deemed to be the least controllable symptom and Behavioural Problems were considered the most controllable. Relationships existed between the attributions made by clients and relatives. Depression in clients was related to them attributing their illness to personal factors, and a reporting negative feelings about there relationship with a key relative. Findings are discussed in relation to literature, research and clinical practice.
Magnetic and superconducting correlations in the two-dimensional Hubbard model

description: The interplay and competition of magnetic and superconducting correlations in the weakly interacting two-dimensional Hubbard Model is investigated by means of the functional renormalization group. At zero temperature the flow of interactions in one-loop approximation evolves into a strong coupling regime at low energy scales, signalling the possible onset of spontaneous symmetry breaking. This is further analyzed by a mean-field treatment of the strong renormalized interactions which takes into account magnetic and superconducting order simultaneously. The effect of strong correlations on single-particle properties in the normal phase is studied by calculating the flow of the self-energy.

description: After a long period of prosperity, the Únĕtice (2300-1600 B.C.) – a Central European Early Bronze Age culture – collapsed in few decades without obvious reason. Since Únĕtice was the first bronze metalworkers of Central Europe, we examine whether the reduced availability of bronze could have triggered the social collapse. We claim that it could have been so since such reduction could have implied changed trade routes, socio-economic turmoil and severe disruption of the social stratification. We provide a detailed analysis of two reasons related to shortages of inputs used to produce bronze which could explain the demise of bronze production. The first is about tin ores which could have been exhausted or become extremely scarce since only alluvial deposits of tin were used by followers of the Únĕtice culture. The second is about wood since the production of bronze requires huge quantities of wood and charcoal used as fuel, leading to deforestation. Both reasons are complementary, and combined with the reduced productivity of agriculture implied by the anthropogenic pressure on ecosystems, all three may have led to a bronze crisis, and the demise of the Únĕtice culture.
title: A qualitative study exploring relatives' experience of seeking help for a person during the early stages of schizophrenia
Creators: name: Pearse, Wendy Ann
Publisher: name: The Open University
Year: 1998

description: Background Research suggests that early intervention for schizophrenia improves prognosis and prevents relapse, but factors which influence early access to services still remain unclear. Two factors which have been implicated, however, are family involvement and gender of the person. Aims The current study set out to explore relatives' experience of seeking help for a person during the early stages of schizophrenia. This was to be considered in general terms and with particular reference to the influence that the gender of the person had on this process. Participants Clients with a diagnosis of schizophrenia in the last fifteen years were identified through routine clinical services and their permission sought to contact a relative. Eight relatives of men, and eight relatives of women, with schizophrenia were recruited. Methodology A qualitative, methodology was used. Relatives were interviewed about their experience using a semi-structured interview schedule. Results were analysed using a Grounded Theory method (Glaser and Strauss, 1990). Major Findings A theoretical framework for understanding the process of relative's adjustment to their experience was developed. The framework suggests that there are four inter-related phases that relatives go through during their help seeking experience. The framework also suggests that resolution is achieved when relatives' needs are adequately met in the following four areas: Understanding; Action; Integration of Difference; and Communication/Interaction. implications for Clinical Practice, Service Delivery and further research are discussed.
