The purpose of this study was to investigate the effects of feed ingredients with different protein-to-fat ratios on growth, slaughter performance and meat quality of Small-Tail Han lambs. Forty-five Small-Tail Han lambs (♂) (BW = 34.00 ± 2.5 kg, age = 120 ± 9 d) were randomly divided into groups with three different experimental treatments: (1) PF 5, with the ratio of protein to fat (CP:EE) of 50 to 5; (2) PF10, CP: EE = 50:10; (3) PF20, CP: EE = 50:20. Each treatment group had 15 lambs, and each sheep was a repeat. This experiment lasted for 65 days, with feed intake recorded daily, and animals being weighed on days 0, 30, and 65. At the conclusion of the experiment, eight lambs from each group were slaughtered to assess slaughter performance and meat quality. The results showed that the average daily gain (ADG) of the three groups were 315.27, 370.15 and 319.42 g/d, respectively. The PF10 group had the highest ADG (370.15 g) (p < 0.05). Forestomach weights (1216.88 g) of the PF10 group were significantly higher than those of the other groups (p < 0.05). There were no differences (p > 0.05) in fat percentages in various parts of body among treatments. Feed conversion of the PF10 group was higher (p < 0.05) than that of PF 5 and PF 20 groups. Furthermore, the PF10 group had a higher (p > 0.05) carcass weight and slaughter rate and there were few differences between the other groups in terms of dry matter intake, meat quality, organ weight, and fat deposition (p > 0.05). The protein–energy supplement with protein-to-fat ratio, PF10 appeared to be more desirable to promote the growth and development in Small-Tail Han Lambs.

Wearable devices in sports have been used at the professional and higher collegiate levels, but not much research has been conducted at lower collegiate division levels. The objective of this retrospective study was to gather big data using the Catapult wearable technology, develop an algorithm for musculoskeletal modeling, and longitudinally determine the workloads of male college soccer (football) athletes at the Division III (DIII) level over the course of a 12-week season. The results showed that over the course of a season, (1) the average match workload (432 ± 47.7) was 1.5× greater than the average training workload (252.9 ± 23.3) for all positions, (2) the forward position showed the lowest workloads throughout the season, and (3) the highest mean workload was in week 8 (370.1 ± 177.2), while the lowest was in week 4 (219.1 ± 26.4). These results provide the impetus to enable the interoperability of data gathered from wearable devices into data management systems for optimizing performance and health.

This study aims to determine the quantitative characteristics of the crossbreed Bali cattle with several male breeds such as the Ongole, Limousine, and Simmental breeds. The method used in this research is the observation method in the form of direct observation in the field and measurement of cattle. A total of 30 adult cattle aged 1.5-2 years, consisting of 10 heads each (5 males and 5 females) crosses through Artificial Insemination (AI) of Bali cattle using frozen semen of Ongole breed bulls (POBAL), Limousin (LIMBAL) and Simmental (SIMBAL). The results showed that POBAL cattle had an average body length of 114.4-116.0 cm, chest circumference 179.4-220.0 cm, shoulder height 126.2-143.8 cm, and body weight 407.15-586.84 kg . LIMBAL cattle have an average body length ranging from 129.4-151.2 cm, chest circumference 170.4-191.8 cm, shoulder height 123.0-151.6 cm, and body weight 370.184-457.122 kg. While the average body length for SIMBAL cattle ranges from 159.8-180.0 cm, chest circumference 166.6-219.8 cm, shoulder height 125.8-154.1 cm, and body weight 356.662-584.678 kg.

Research has been conducted on the manufacture of PLA Coir Bentonite composites. This study aims to examine the effect of PLA on mechanical strength with the addition of coir and bentonite fillers from North Aceh and Central Aceh. The sample formulations used were single polymer PLA/Coir and PLA/Coir with variations of filler Bentonite Aceh Utara and Aceh Tengah with 2, 4, 6 and 8% respectively. The combination of PCa samples showed the highest bacterial colony growth rate, which was more than 100 colonies/gram during the 1 week testing period. In the PBATd filler mixture sample, the maximum bacterial test value was 65 colonies/gram and the minimum value contained in the PBAUa sample was 105 colonies/gram. The best tensile strength was obtained in the PBATc sample, namely 65 MPa. PBATd samples began to degrade at 370.15oC compared to PCa samples degraded at 280.21oC. While the PBAUa sample began to degrade at a temperature of 282.11oC. The surface structure of the PCa sample is more homogeneous because there is no bentonite filler mixture, but it is brittle and crumbles easily. For the PBATd sample, the surface structure is smoother and more homogeneous compared to the PBAUa sample.

The Mount Pleasant granite-related polymetallic deposit, located on the southwestern margin of the Late Devonian to Early Carboniferous Mount Pleasant Caldera Complex in southwestern New Brunswick, contains a significant resource of tin, tungsten, molybdenum, zinc, indium, and bismuth. The Caldera Complex comprises Intracaldera, Exocaldera, and Late Caldera-Fill sequences and associated subvolcanic granitic rocks. Three granitic phases of the Mount Pleasant Granitic Suite (Granite I, II, and III) are recognized in the vicinity of the Mount Pleasant deposit and are interpreted to be fractionates of the more regionally exposed McDougall Brook Granitic Suite. Granite I and Granite II are associated with tungsten-molybdenum-bismuth, and tin-zinc-indium mineralization, respectively. Despite extensive research within the Caldera Complex, the exact age of mineralization at Mount Pleasant has never been firmly established. An inferred age of 363 ± 2 Ma was based on the proposed synchronicity of the U-Pb dated Bailey Rock Rhyolite of the Exocaldera Sequence with that of the undated McDougall Brook Granitic Suite, which intrudes the Intracaldera Sequence. Here, we present Re-Os dating of two molybdenite samples associated with the tungsten mineralization related to Granite I at the Fire Tower Zone, that constrain the initial onset of mineralization at Mount Pleasant to be between 369.7±1.6 Ma and 370.1±1.7 Ma. The new Re-Os ages clearly indicate that the McDougall Brook Granitic Suite, which pre-dates mineralization, must be at least seven million years older than the Bailey Rock Rhyolite, whose type-section is located within the Exocaldera Sequence. A re-examination of the gradational relationship between the McDougall Brook Granitic Suite and purported rocks of Bailey Rock Rhyolite within the Intracaldera Sequence revealed that the latter should instead be assigned to the Seelys Formation. Thus, deposition of the polymetallic mineralization likely took place contemporaneously with caldera collapse and an early phase of resurgent doming in response to degassing of the magma chamber rather than being coincident with erosion of the volcanic edifice as inferred from previous modeling of the eruptive history at Mount Pleasant.

It has been demonstrated that athletes in competitive sports suffer from high levels of competitive anxiety, especially in the case of females. In this sense, it is necessary to identify possible risk and protective factors of those athletes in this collective who suffer from this type of anxiety. However, few studies analyze the relationship between Physical Activity (PA) and anxiety, identifying the possible mediation effect of trait variables such as impulsivity and mindfulness in female athletes. Hence, the aims of this study were: to determine differences between PA levels with anxiety, mindfulness, and impulsiveness; to identify the predictive value of sociodemographic factors and physical activity, impulsivity, and mindfulness on anxiety factors; and to analyze the possible mediating effects of mindfulness on the relationship between impulsivity and anxiety. A total of 242 female athletes underwent an assessment of physical activity, anxiety, mindfulness traits, and impulsivity using validated questionnaires. Data were analyzed according to (1) individual or collective sport, and (2) PA levels according to energy expended (METs min/day). Participants were grouped by light, moderate, and vigorous PA levels. There were 30.5% elite athletes and 73.2% collective sports athletes. Mean age was 22.1 years and mean light, moderate, and vigorous PA were 86.1 ± 136.2, 114.4 ± 159.8, and 370.1 ± 336.3 METs min/day, respectively. Those athletes performing vigorous PA exhibited lower levels of impulsiveness and higher mindfulness traits. As expected, the mindfulness trait was a mediating factor in the relationship between impulsiveness and each factor of competitive anxiety (cognitive, somatic, and self-efficacy). Female athletes could suffer competitive anxiety, especially those who present higher levels of impulsivity. However, higher levels of mindfulness traits seem to be a protective factor in the effects of impulsivity on anxiety in this population and have demonstrated to be significant mediators in this association. Further studies are needed with other female athletes to replicate these results and to determine the specific protective mechanisms of mindfulness traits in preventing competitive anxiety.

Abstract. Atmospheric airborne measurements of CO2 are very well-suited to estimate the time varying distribution of carbon sources and sinks at the regional scale. We present here an analysis of two cross-European airborne campaigns that have been carried out on 23–26 May 2001 (CAATER 1) and 2–3 October 2002 (CAATER 2) over Western Europe. The area covered during CAATER 1 (respectively CAATER 2) was comprised between longitude 4° W to 14° E and latitude 44° N to 52° N (respectively longitude 1° E to 17° E and latitude 46° N to 52° N). High precision in-situ CO2, CO and Radon 222 measurements have been recorded. Flasks samples have been collected during both campaigns to cross-validate the in-situ data. During CAATER 1 (respectively CAATER 2), the mean CO2 concentration was 370.1±4 ppm (respectively 371.7±5 ppm). A HYSPLIT backtrajectories analysis shows that during CAATER 1, dominant winds were blowing from the north-west. In the planetary boundary layer (PBL) airmasses got contaminated over Benelux and Western Germany by pollution from these high urbanized areas, reaching about 380 ppm. Air masses passing over rural areas are depleted in CO2 because of the photosynthesis activity of the land cover vegetation, as low as 355 ppm. During CAATER 2, the backtrajectory analysis shows that airmasses were distributed among the 4 sectors. Airmasses got enriched in CO2 and CO when passing above polluted spots in Germany but also in Poland, as these countries are known to hold part of the most polluting plants based on coal consumption, the so-called "dirty thirty" from WWF. Simultaneous measurements of in-situ CO2 and CO combined to backtrajectories helped us to discriminate the role of fossil fuel emissions from over CO2 sources. The ΔCO/ΔCO2 ratios (R2=0.33 to 0.88, slopes=2.42 to 10.37), calculated for polluted airmasses originating from different countries/regions, matched quite well national inventories, showing that the airborne measurements can help to identify the role of fossil fuel sources even several days/hundreds of kms further in the PBL. CO2 observations have been compared to surrounding ground stations measurements, confirming that the stations located near the ground (ex. CBW, WES, HUN) are representative of the local scale, while those located in the free troposphere (FT) are representative of atmospheric CO2 on a regional scale of a few hundred kilometers (ex. CMN). Stations located several 100 km away measure CO2 concentrations different from a few ppm, indicating the existence of a gradient of a few ppm in the free troposphere. Observations at stations located on top of small mountains (ex. SCH, PUY) match or not the airborne data whether they sample air from the FT or air coming up from the valley. Finally, the analysis of the CO2 vertical variability conducted on the 14 profiles recorded per campaign shows that is at least 5 to 8 times higher in the PBL (4 ppm and 5.7 ppm for CAATER 1 and CAATER 2, respectively) than in the FT (0.5 ppm and 1.1 ppm for CAATER 1 and CAATER 2, respectively). The CO2 jump between the PBL and the FT equals 3.7 ppm for the first campaign and −0.3 ppm for the second campaign. A very striking zonal CO2 gradient of about 11 ppm could be observed in the mid-troposphere during CAATER 2, with higher concentrations in the West than in the East. This gradient could originate from differences in atmospheric mixing, ground emission rates or a earlier beginning of the Fall in the west. More airborne campaigns are currently under analysis in the framework of the CARBOEUROPE-IP project to better assess the role of these different hypothesis. In a companion paper (Xueref-Remy et al., 2010), a comparison of vertical profiles from observations and several modeling frameworks is conducted for both campaigns. An attempt to calculate CO2 fluxes during CAATER 1 using CO2 and Radon-222 observations and modeling tools is also carried out.

Abstract. Atmospheric airborne measurements of CO2 are very well suited for estimating the time-varying distribution of carbon sources and sinks at the regional scale due to the large geographical area covered over a short time. We present here an analysis of two cross-European airborne campaigns carried out on 23–26 May 2001 (CAATER-1) and 2–3 October 2002 (CAATER-2) over Western Europe. The area covered during CAATER-1 and CAATER-2 was 4° W to 14° E long; 44° N to 52° N lat and 1° E to 17° E long; 46° N to 52° N lat respectively. High precision in situ CO2, CO and Radon 222 measurements were recorded. Flask samples were collected during both campaigns to cross-validate the in situ data. During CAATER-1 and CAATER-2, the mean CO2 concentration was 370.1 ± 4.0 (1-σ standard deviation) ppm and 371.7 ± 5.0 (1-σ) ppm respectively. A HYSPLIT back-trajectories analysis shows that during CAATER 1, northwesterly winds prevailed. In the planetary boundary layer (PBL) air masses became contaminated over Benelux and Western Germany by emissions from these highly urbanized areas, reaching about 380 ppm. Air masses passing over rural areas were depleted in CO2 because of the photosynthesis activity of the vegetation, with observations as low as 355 ppm. During CAATER-2, the back-trajectory analysis showed that air masses were distributed among the 4 sectors. Air masses were enriched in CO2 and CO over anthropogenic emission spots in Germany but also in Poland, as these countries have part of the most CO2-emitting coal-based plants in Europe. Simultaneous measurements of in situ CO2 and CO combined with back-trajectories helped us to distinguish between fossil fuel emissions and other CO2 sources. The ΔCO/ΔCO2 ratios (R2 = 0.33 to 0.88, slopes = 2.42 to 10.37), calculated for anthropogenic-influenced air masses over different countries/regions matched national inventories quite well, showing that airborne measurements can help to identify the origin of fossil fuel emissions in the PBL even when distanced by several days/hundreds of kms from their sources. We have compared airborne CO2 observations to nearby ground station measurements and thereby, confirmed that measurements taken in the lower few meters of the PBL (low-level ground stations) are representative of the local scale, while those located in the free troposphere (FT) (moutain stations) are representative of atmospheric CO2 regionally on a scale of a few hundred kilometers. Stations located several 100 km away from each other differ from a few ppm in their measurements indicating the existence of a gradient within the free troposphere. Observations at stations located on top of small mountains may match the airborne data if the sampled air comes from the FT rather than coming up from the valley. Finally, the analysis of the CO2 vertical variability conducted on the 14 profiles recorded in each campaign shows a variability at least 5 to 8 times higher in the PBL (the 1-σ standard deviation associated to the CO2 mean of all profiles within the PBL is 4.0 ppm and 5.7 ppm for CAATER-1 and CAATER-2, respectively) than in the FT (within the FT, 1-σ is 0.5 ppm and 1.1 ppm for CAATER-1 and CAATER-2, respectively). The CO2 jump between the PBL and the FT equals 3.7 ppm for the first campaign and −0.3 ppm for the second campaign. A very striking zonal CO2 gradient of about 11 ppm was observed in the mid-PBL during CAATER-2, with higher concentrations in the west than in the east. This gradient may originate from differences in atmospheric mixing, ground emission rates or Autumn's earlier start in the west. More airborne campaigns are currently under analysis in the framework of the CARBOEUROPE-IP project to better assess the likelihood of these different hypotheses. In a companion paper (Xueref-Remy et al., 2011, Part 2), a comparison of vertical profiles from observations and several modeling frameworks was conducted for both campaigns.

Abstract Background: Gene expression profiling (GEP) is increasingly being integrated into clinical practice for prognostication of multiple myeloma. MyPRSTM utilizes the 70-gene panel with survival data derived from cohorts of myeloma patients treated under intensive clinical trial regimens including tandem transplants. We aim to validate and expand the prognostic impact of GEP characterization of myeloma in patients treated with various anti-myeloma therapies at a single academic center. Methods: MyPRSTM GEP analysison bone marrow aspirate sampleswas performed on 417 multiple myeloma patients atMoffitt Cancer Center who had bone marrow examination at different phases in the course of their disease. Myeloma risk prognostication was conducted based on the risk classification (cutoff of score 45.2), risk score (0-100), and molecular subtyping. Trend (Jonckheere-Terpstra) test was performed to evaluate the associations of GEP scores and molecular subtypes. Overall survival (OS) was estimated using the Kaplan-Meier method from the time of GEP analysis and OS curves were compared using the log-rank test. Multivariate Cox proportional hazards regression models were built for OS. Results: Median age was 62 (range, 21-86), majority of patients were male (57.6%) and 71 patients (17%) had high-risk disease based on GEP with a median score of 30.7 (range, 8.7-99.4). Median time from myeloma diagnosis to GEP was 15.8 (range, 0.1-370.1) months. Molecular subtypes werehyperdiploidy(HY) 25.2%, cycle family (CD)-2 21.1%, low bone disease (LB) 17.5%, proliferation (PR) 13.4%, MMSET associated (MS) 9.8%, MAF associated (MF) 7.7%, and CD-1 5.1%. There was an increasing trend of higher GEP scores among various molecular subtypes from CD to PR (p<0.001). OS estimates for all patients were 75% (95%CI: 70-81%) at 2 years. OS was significantly inferior in patients with high-risk by GEP, 51% (95%CI: 69-37%) vs. 80% (95%CI: 86-75%) at 2 years regardless of disease status (Figure 1, p<0.001). Molecular subtypes predicted OS (p<0.001). When MF, MS and PR subtypes were combined, they had inferior OS compared to others (p<0.001): 67% (95%CI: 58-77%) vs. 90% (95%CI: 87-94%), 53% (95%CI: 43-66%) vs. 85% (95%CI: 80-90%), and 43% (95%CI: 31-60%) vs. 76% (68%-85%) at 1, 2 and 3 years, respectively. When patients were re-classified based on the median GEP score of 30.69, OS was significantly worse for those with GEP scores higher than the median (n=209, p<0.001, Figure 2). When patients were divided into 4 categories ([1] scores 0-20, 20-40, 40-60, 60-100, or [2] quartiles), both were predictive of distinct survival groups (p<0.001 for both, Figure 2). In multivariate analyses fitting the models with GEP score, GEP risk groups and molecular subtypes, GEP score (hazard ratio (HR) 1.05, 95%CI: 1.04-1.07, p<0.001) and GEP risk group (HR 2.39, 95%CI: 1.45-3.95, p<0.001) were the independent predictors of inferior OS. Conclusions: Analysis of GEP in myeloma patients irrespective of disease status treated at a single academic institution validates the prognostic significance based on 70-gene GEP score, risk groups and molecular subtyping. Although less robust, GEP risk re-classification with a new threshold value based on the median also demonstrates prognostic significance. Interestingly, parsing of the GEP-70 score by separating patients into different GEP score groups (either in 20-point increments or quartiles) results in distinct groups with distinct survival characteristics suggesting powerful prognostic value of GEP analysis. To this end, a higher GEP score was associated with a worse prognostic score even within the same GEP risk classification. These data indicate the potential for the development of a new risk classification based on GEP score into 4 risk groups. Increased numbers of patients will be required to validate the potential of these score-based risk classifications. In conclusion, our data demonstrate that GEP score remains a powerful prognostic tool regardless of the disease setting. Figure 1 (OS by GEP risk: high vs. low) Figure 1.

For some years now Government and Local Authorities have been concerned about the educational achievements and life chances of Looked After Children and research has highlighted that these children can experience major problems. It is perhaps surprising, therefore, that little is known specifically about a group of Looked after Children in the Local Authority in which I work and hence the aim of this study was to gain an understanding of a group of Key Stage 2 Looked After Children in order to compare their personal and educational outcomes with other Looked After Children across the country and also to inform policy and practice in the Local Authority and in the Educational Psychology Service where I work. This study aimed to identify the strengths and needs of Looked After Children cared for by the local authority in which I practice in order to establish whether the traditional way in which Looked After Children access the Educational Psychology Service is appropriate. The emergent objectives were to understand the demographic characteristics of Looked After Children, to examine how well they perform in respect of cognition and educational achievement, to establish their levels of emotional wellbeing and finally, to establish what factors seem to promote resilience in the Looked After Children population. The research design employed a combination of qualitative and quantitative methods. Data analysis of local authority records (education and social care), interviews, questionnaires and psychoeducational assessment instruments were utilised. The study found that, as a group, Key Stage 2 Looked After Children fair well in terms of psychoeducational outcomes. However, at an individual level some children had specific compounding psychoeducational needs which would clearly suggest the need for support from Local Authority Services, including the Educational Psychology Service. The study also indicates that a balance needs to be struck between strategic intervention and individual support in order to meet the needs of this vulnerable group of children.

The English language enjoys a growing status in Israeli society (Spolsky & Shohamy, 1999; Stavans & Narkiss, 2001, 2003). This has resulted in a steady growth in teaching of English for young learners (EYL) in schools and in an official recommendation for teaching EYL in Grades 1 and 2 nationwide. This educational initiative seems a socio-cultural phenomenon, shaped by external forces of globalisation and socio-political trends (Crystal, 1997, 2003; Pennycook, 1994; Graddol, 2006) affecting and reflecting people's identities (Norton, 1997,2000; Norton Peirce, 1995), social practices and ideologies. Critical discourse analysis is used as the theoretical framework and analytical tool (Gee 1999,2005) for the examination and analysis of discourses mobilised by parents, teachers, position-holders and pupils, for the ways in which they enact their identity ('ways of being') and construe the hybrid Discourse of EYL. Analysis of 33 in-depth semi-structured interviews and samples of published texts reveal a range of commonsense dominant Discourses such as the `Discourse of consumerism', the Discourse of the `good, Jewish/Israeli parents' and the `Discourse of Americanisation and internationalisation' to which the actors involved wish to belong. Findings illuminate that the forces behind the promotion of EYL seem to be driven by social, ideological and political concerns rather than pedagogical ones. The Discourse of EYL (and the D/discourses from which it is construed) seems to have a regulating effect on social, educational decisions, schools' policy and classroom practices, and the distribution of goods, shaping people's everyday life. There is evidence for the possibility that people in Israel (parents in particular) project themselves, with hopes and desire, into an idealised, abstract, global world of `knowing English' in which EYL plays a major part. Findings highlight the ways in which the attitude of Jews in Israel towards learning languages is a marker of their identity.

This thesis consists of two volumes. The first is a literature review exploring the development of aggression in adolescent males with a summary of research that outlines a complex multi-factor trajectory across the lifespan towards aggression in males. The literature review focuses on how flawed social cognitive processes act as a proximal mechanism that facilitates aggressive and violent responses during social interactions and how a social information processing model has been proposed to explain aggression in adolescent males. The second paper presents findings for an empirical study of adolescent males with either high or low levels of aggression who completed a visual probe task with emotive facial image stimuli. The paper represents the first study employing a visual probe design with a sample of adolescent males identified with high levels of aggression. Findings revealed evidence of reduced attentional bias to angry expressions (angry) in those with high levels of aggression compared to non-aggressive controls. Implications for social information processing theory are discussed.

Paper 1: This study represents the wider perspective of a 2-stage study about school transfers, for children with Autistic Spectrum Disorders. The study used a mixed methodology to investigate the experiences of children moving schools, as reported by parents and schools. Pre-move general satisfaction and post-move success ratings were high. Transfer arrangements varied greatly. Many respondents despite being positive overall about the move reported difficulties and frustrations for themselves and the children making the move. Communication between all stakeholders was seen to be a main factor in improving transfers, with an emphasis on the Teaching Assistant role and a whole school ethos towards ASD. Although strategies and guidance are widely available to improve transfer for children, not all pupils with ASDs and their parents, had access to the same level of enhanced transfer arrangements within the county. Paper 2: This paper represents the more focussed perspective of a 2- stage study about school transfers, for children with Autistic Spectrum Disorders, in mainstream education. The study used a mixed methodology to investigate the experiences of children moving schools, as reported by parents and schools, with all participants, and via child interviews with a smaller sample. School transfer (as part of a 2- or 3-tier education system) was identified as a time which can be especially challenging for children with ASDs in mainstream schools. Looking at the emotional effects of transfer, the study found parents and schools reported high levels of increased anxiety among transferring children with ASDs. Qualitative analysis identified a wide variety of triggers to anxiety, and strategies to reduce anxiety that are being used in school and at home. Positive emotions expressed about the move were also explored. This anxiety reduced post-move for some of the children, but was maintained for some. Parents perceived higher levels of anxiety in their children than schools did throughout the transfer period, despite many rating the move as successful overall. The experience of a school move was found to be a time parents, as well as children, need the information and reassurance of a well-planned transfer, with appropriate strategies in place for their child and effective, open communication between home and schools to reduce the negative emotions that can surround change for children with ASDs, and celebrate the positive.

Woodward, Sophie. "To what extent can a guided imagery intervention designed to enhance self-esteem help to reduce social exclusion in key stage 2?" Thesis, University of Nottingham, 2010. http://eprints.nottingham.ac.uk/13090/.
Pełny tekst źródłaStreszczenie:
The topics of self-esteem and social inclusion have been subject to much research in educational psychology, with positive correlation often being found to exist between the two. However, very little research has been conducted into the efficacy of guided imagery - a person-centred cognitive therapeutic technique – on enhancing either self-esteem or social inclusion, particularly in school-age populations. Identifying the gap in existing literature, this study therefore assessed the extent to which a five-session guided imagery intervention was associated with increases in both self-esteem (as measured by the Lawrence Self-Esteem Questionnaire; Lawrence, 1982) and social inclusion (as measured by the Social Inclusion Survey; Frederickson & Graham, 1999, and the Peer Problems and Prosocial Behaviour subscales of the Strengths and Difficulties Questionnaire; Goodman, 1997). This quantitative data was supplemented by a limited collection of qualitative questionnaire data, which was analysed using content analysis. Both forms of data were collected from 46 Year 4 and 5 pupils from three mainstream primary schools, who had been randomly allocated either to experimental groups or waiting list control groups. Qualitative data was also collected from the four members of school staff who had been trained in facilitating the intervention. Data analysis indicated that the guided imagery intervention had few salient effects on self-esteem or social inclusion as measured by the instruments used, but there was some qualitative evidence of increased self-esteem and social inclusion of participants in the experimental condition. The results of this study are discussed in the context of existing literature, and implications for future research and practice are explored.

Abstract Temporary plugging fracturing technology is an effective way to control fracture propagation in shale oil and gas development. However, insufficient plugging pressure often causes the failure to promote new fractures. Therefore, it is essential to reduce plugging permeability and increase plugging pressure. The permeability of the plugging zone is closely related to its pore structure, so the quantitative study of microscopic pore structure can provide a basis for reducing permeability. This paper introduces a new method based on micro-CT to characterize the microstructure of temporary plugging zones. Three kinds of particulate temporary plugging agents with sizes of 2-4mm, 1-2mm, and 0.4-0.8mm were used as the research objects. The samples of the temporary plugging zone in natural accumulation and compaction state were prepared by a self-made mold. The total pore structure and parameters (porosity, pore radius, pore throat, and tortuosity) were obtained by three-dimensional (3D) reconstruction of CT images. Finally, the displacement device was used to test the plugging pressure of the temporary plugging zone. Under natural accumulation, the porosity and tortuosity of the temporary plugging zone are independent of particulate size. The pore radius decreases with the decrease of particulate size. In the compaction state, particulates and particulates are cemented with each other, resulting in apparent changes in the pore structure. With the decrease in particulate size, the pore structure changes more obviously. For example, the pore radius of 2-4mm decreases from 889.27um to 736.33um, while the pore radius of 0.4-0.8mm decreases from 370.15um to 63.94um, with a reduction of 82.9%. The plugging pressure test results are consistent with the microscopic pore results. In conclusion, the smaller the particulate, the easier the particulate compression deformation, the smaller the pore radius and porosity, and the denser the plugging zone. Although small particulate-size temporary plugging agents can produce large pressure, forming an effective plugging zone in the fracture is difficult. Therefore, large particulates can bridge the fracture, and small particulates are filled in the pores of the plugging zone formed by large particulates to generate a tight plugging zone. In this paper, we provide a new application of Micro-CT for quantifying the microstructure of the temporary plugging zone. The effect of the properties of the temporary plugging agent on the structure of the plugging zone can be clarified from the microscopic point of view by using this method, which provides a new means for the design and optimization of temporary plugging materials.
