Thinking in three dimensions: Exploring students' geometric thinking and spatial ability with the Geometer's Sketchpad

Current reform initiatives recommend that geometry instruction include the study of three-dimensional geometric objects and provide students with opportunities to use spatial skills in problem-solving tasks. Geometer's Sketchpad (GSP) is a dynamic and interactive computer program that enables the user to investigate and explore geometric concepts and manipulate geometric structures. Research using GSP as an instructional tool has focused primarily on teaching and learning two-dimensional geometry. This study explored the effect of a GSP based instructional environment on students' geometric thinking and three-dimensional spatial ability as they used GSP to learn three-dimensional geometry. For 10 weeks, 18 tenth-grade students from an urban school district used GSP to construct and analyze dynamic, two-dimensional representations of three-dimensional objects in a classroom environment that encouraged exploration, discussion, conjecture, and verification. The data were collected primarily from participant observations and clinical interviews and analyzed using qualitative methods of analysis. In addition, pretest and posttest measures of three-dimensional spatial ability and van Hiele level of geometric thinking were obtained. Spatial ability measures were analyzed using standard t-test analysis. ^ The data from this study indicate that GSP is a viable tool to teach students about three-dimensional geometric objects. A comparison of students' pretest and posttest van Hiele levels showed an improvement in geometric thinking, especially for students on lower levels of the van Hiele theory. Evidence at the p < .05 level indicated that students' spatial ability improved significantly. Specifically, the GSP dynamic, visual environment supported students' visualization and reasoning processes as students attempted to solve challenging tasks about three-dimensional geometric objects. The GSP instructional activities also provided students with an experiential base and an intuitive understanding about three-dimensional objects from which more formal work in geometry could be pursued. This study demonstrates that by designing appropriate GSP based instructional environments, it is possible to help students improve their spatial skills, develop more coherent and accurate intuitions about three-dimensional geometric objects, and progress through the levels of geometric thinking proposed by van Hiele. ^

The Prison System and the Media: How “Orange Is The New Black” Engages with the Prison as a Normalizing Agent

The purpose of this project is to ascertain the ways in which Orange is the New Black uses its platform to either complicate or reify narratives about the prison system, prisoners and their relationship to the state. This research uses the works of Giorgio Agamben, Colin Dayan, Michelle Alexander and Lisa Guenther to situate the ways the state uses the prison and social narratives about the prison to extend its control on certain populations beyond prison walls through police presence, parole, the war on drugs and prison fees. From that basis, this work argues that while Orange does challenge some narratives about race and sexuality, because of its reliance on “bad choices” as a humanizing trope and its reliance on certain racialized stereotypes for entertainment, the show ultimately does more to reify existing narratives that support state interests.

Psychosocial variables associated with the co-occurance of risky sexual behavior with alcohol consumption among university students

This study examined the association of theoretically guided and empirically identified psychosocial variables on the co-occurrence of risky sexual behavior with alcohol consumption among university students. The study utilized event analysis to determine whether risky sex occurred during the same event in which alcohol was consumed. Relevant conceptualizations included alcohol disinhibition, self-efficacy, and social network theories. Predictor variables included negative condom attitudes, general risk taking, drinking motives, mistrust, social group membership, and gender. Factor analysis was employed to identify dimensions of drinking motives. Measured risky sex behaviors were (a) sex without a condom, (b) sex with people not known very well, (c) sex with injecting drug users (IDUs), (d) sex with people without knowing whether they had a STD, and (e) sex with using drugs. A purposive sample was used and included 222 male and female students recruited from a major urban university. Chi-square analysis was used to determine whether participants were more likely to engage in risky sex behavior in different alcohol use contexts. These contexts were only when drinking, only when not drinking, and when drinking or not. The chi-square findings did not support the hypothesis that university students who use alcohol with sex will engage in riskier sex. These results added to the literature by extending other similar findings to a university student sample. For each of the observed risky sex behaviors, discriminant analysis methodology was used to determine whether the predictor variables would differentiate the drinking contexts, or whether the behavior occurred. Results from discriminant analyses indicated that sex with people not known very well was the only behavior for which there were significant discriminant functions. Gender and enhancement drinking motives were important constructs in the classification model. Limitations of the study and implications for future research, social work practice and policy are discussed.

Understanding the work of the city manager

The managerial behaviour approach to understanding managerial work has developed from research over the course of fifty years. The approach represents a marked departure from mainstream (and still prevalent) management approaches that depict management as a set of general composite functions. The managerial behaviour approach is distinctive in its empirical research background, object, focus and methodology. Its objective is to provide the simple answer to the complex question: what do managers do? However, the emphasis in the studies on managerial behaviour represents a limitation in so far as a context for locating and judging that behaviour is largely absent (Hales, 1986). This paper presents the results of initial research into managers operating in a different and largely neglected context - city councils. The research uses Mintzberg’s (1973) concept of behavioural roles as an analytical tool to explain and understand what city managers do. This study assesses whether these roles adequately capture the important features of managerial work in the city council. It is argued that while Mintzberg’s role framework is useful, structured observation alone does not adequately address the complexities of environments and styles of managers or the cognitive processes of managers. However, by integrating this approach with an appreciation of context and cognitive processes and how they can influence or affect managerial behaviour, we develop a more realistic description of what managers actually do and why they do it.

Migrant women’s employment in paid reproductive work through the crisis: the case of Italy (2007-2012)

Paid reproductive work, especially in the case of cleaning and home-care for elderly people, is an important sector for foreign women in Italy. For this reason, since the beginning of the current economic crisis, scholars have wondered about the impact of the recession on migrant domestic workers. They have looked particularly at possible competition with Italian women entering the sector for lack of better alternatives. Our paper takes this discussion a step further by assessing the overall changes affecting migrant women in the Italian labour market, 2007-2012. We will look at how their position has been transformed, by taking both an ethnic perspective, in relation to Italian women, and a gender perspective, in relation to migrant men. By way of a conclusion, the argument will be made that there is a substantial lack of competition between Italian and foreign women in the care and domestic sector due to differences in their earnings, hours of work and activities.

Chemotherapy patient perception regarding communication with the healthcare staff

Purpose: To qualitatively explore the communication between healthcare professionals and oncology patients based on the perception of patients undergoing chemotherapy.Method: Qualitative and exploratory design. Participants were 14 adult patients undergoing chemotherapy at different stages of the disease. A socio-demographic and clinical data form was utilized along with semi-structured interviews. The interviews were audio-recorded, transcribed and content analysis was performed. Two independent judges evaluated the interview content in regards to emerging categories and obtained a Kappa index of 0.834.Results: Three categories emerged from the data: 1) Technical communication without emotional support, in which the information provided is composed of strictly technical information regarding the diagnosis, treatment and/or prognosis; 2) Technical communication, in which the information provided is oriented towards the technical aspects of the patient’s physical condition, while also providing psychological support for the patients’ subjective needs; and 3) Insufficient technical communication, win which there are gaps in the information provided causing confusion and suffering to the patient.Conclusions: Communication with emotional support contributes to greater satisfaction of chemotherapy patients. Practical implications: the results provide elements for the training of healthcare professionals regarding the importance of the emotional support that can be offered to cancer patients during their treatment.

Analyzing Gene Centres with the Help of the Checklist Method – the Case of Syria

The present survey of species diversity of cultivated plants is the first for Syria. Some cultivated species will be added in the future, because due to the civil war in Syria, it was not possible to visit the country in the frame of the present work, as initially planned. Checklists proved to be a useful tool for overviewing the cultivated plants of selected areas and allow a characterization of the state of plant genetic resources of Syria. Syria has experienced several civilizations. Man settled in this productive land since ancient times and used its resources. However, such use has led to changes in vegetation and decline of wildlife through the country, in seashore areas, interior, mountains, and grassland. Plant domestication and growing started more than 10,000 years ago in West Asia. Since then, plentiful of economic plant species were present and used by man and his domesticated animals. Forming a part of the Fertile Crescent, where many of the world’s agricultural plants have evolved, Syria is extremely rich in agrobiodiversity. Wild progenitors of wheat and barley and wild relatives of many fruit trees such as almonds and pistachio as well as forage species are still found in marginal lands and less disturbed areas. These are threatened by a wide range of human activities, notably modern, extensive agriculture, overgrazing, overcutting and urban expansion. Syria is also considered as part of one of the main centres of origin, according to Vavilov, who had collected in Syria in 1926. The first expeditions to crop fields showed the exclusive nature of cultivated plants in Syria with a high number of endemic forms. Furthermore, Syria is a part of a biodiversity hotspot. Several studies have been performed to study agrobiodiversity in different parts of Syria, but usually on wild species. Many collections have been carried out; however, they focussed preferably on cereals and pulses, and particularly on wheat, like Vavilov’s expedition. Only 30 crops make up the major part of the conserved Syrian crop plant material in the genebank, indicating that most of the remaining 7,000 species of cultivated plants and many other valuable genetic resources species have only been included on a limited scale in the genebank collections. Although a small country (185,180 km2), Syria accommodates numerous ecosystems that allow for a large diversity of plant genetic resources for agriculture ranging from cold-requiring to subtropical crops to live and thrive. Only few references are available in this respect. The aim of the present study was to complete a checklist of Syria’s cultivated plants of agriculture and horticulture excluding plants only grown as ornamental or for forestry. Furthermore, plants taken for reforestation have not been included, if they do not have also agricultural or horticultural uses. Therefore, the inclusion of plants into the checklist follows the same principles as “Mansfeld’s Encyclopedia”. Main sources of information were published literature, floras of Syria, Lebanon and the Mediterranean, as well as Syrian printed sources in Arabic and/or English, reports from FAO on agricultural statistics in Syria, and data from ICARDA and Bioversity International. In addition, personal observations gathered during professional work in the General Commission for Scientific Agricultural Research (GCSAR) in Syria (since 1989) and participation in projects were taken into account. These were: (1) A project on “Conservation and Sustainable Use of Dry Land Agrobiodiversity in the Near East” with participation of Jordan, Lebanon, Syria, and the Palestinian Authority, focussing on landraces and wild relatives of barley, wheat, lentil, alliums, feed legumes, and fruit trees (1999–2005). (2) A project for vegetable landraces (1993–1995) in collaboration with the former International Plant Genetic Resources Institute and the UN Development Programme, in which 380 local vegetable accessions were evaluated. For medicinal plants and fruit trees I was in personal contact with departments of GCSAR and the Ministry of Agriculture and Agrarian Reform, as well as with private organizations. The resulting checklist was compared with the catalogues of crop plants of Italy and a checklist of cultivated plants of Iraq. The cultivated plant species are presented in alphabetical order according to their accepted scientific names. Each entry consists of a nomenclatural part, folk names, details of plant uses, the distribution in Syria (by provinces), a textual description, and references to literature. In total, 262 species belonging to 146 genera and 57 families were identified. Within-species (intraspecific) diversity is a significant measure of the biodiversity. Intraspecific diversity for wild plants has been and remains to be well studied, but for crop plants there are only few results. Mansfeld’s method is an actual logical contribution to such studies. Among the families, the following have the highest number of crop species: Leguminosae (34 spp.), Rosaceae (24), Gramineae (18), Labiatae (18), Compositae (14), Cruciferae (14), Cucurbitaceae (11), Rutaceae (10), Malvaceae (9), Alliaceae (7), and Anacardiaceae (7). The establishment of an effective programme for the maintenance of plant genetic resources in Syria started in the mid-1970s. This programme considered ex situ and in situ collection of the genetic resources of various field crops, fruit trees and vegetables. From a plant genetic resources viewpoint, it is clear that the homegarden is an important location for the cultivation of so-called neglected and underutilized species (neglected from a research side and underutilized from a larger economic side). Such species have so far not received much care from ecologists, botanists and agronomists, and they are considerably under-represented in genebanks.

Clinical Psychologists Training and Supervising IAPT Therapists to Work with Long-term Conditions and Medically Unexplained Symptoms: A Service Development Project

An IAPT service and a clinical health psychology team piloted a service development providing Step 2 and Step 3 services for individuals with long-term health conditions. Results indicate that such services may be offered with access to specialist training and supervision.

Review into the Proposed Registration of Teachers and Others who Support Learning in the Independent Sector with the Education Workforce Council

During the passage of the Education (Wales) Bill, Assembly Members called for parity in the way the behaviour of practitioners within maintained schools and the independent sector are regulated. This study was therefore commissioned to gather the views of groups and individuals who work in the education sector in Wales, on whether: i) there should be a requirement for practitioners (both teaching and learning support staff) within independent schools and private FE institutions to register with the Council ii) employers should be legally required to refer cases of unacceptable professional conduct and serious professional incompetence to the Council It was also intended, through this process, to gather views on the potential implications associated with any such registration so that the resulting impact could be identified. The individuals and organisations consulted included head teachers, college principals, governing bodies, teaching staff, learning support staff, trade unions, registration bodies, independent sector representative bodies, inspectorates and teaching councils. Consultations took place between August and November 2015, with data gathered through an online survey, face-to-face interviews, telephone interviews and via email.

Psychotherapeutic work with Families with Life-threatening Maternal Illness

This exploratory research study describes a child and adolescent psychotherapeutic clinical service offered to children/adolescents and their families with mothers with a life-threatening illness. The clinical service itself was also exploratory in nature. The research objectives of the study were (i) to explore whether this form of clinical work could be beneficial for such families in relieving distress and supporting their development; (ii) to discover the factors at play within and between the family members using an adaptation of Grounded Theory research methodology; and (iii) to add to the knowledge base for adults – family members and professionals – relating to, and dealing with, such children and adolescents. Descriptions and discussion of the therapeutic input and research study are given. Symptoms, which included emotional, behavioural, psychological, learning, and interpersonal difficulties, decreased in all the children/adolescents who were offered clinical treatment within an outpatient multidisciplinary Tier 3 Child and Adolescent Service (CAMHS). Six Themes were identified across the cases and these were named: Engagement, Parental Concern, Impact of Mother’s Illness, Defences, Sustaining Factors and Feeling Different. These Themes are discussed in the light of relevant published research. A literature review was undertaken and focuses on: epidemiological context; children’s understanding of death; impact of parental bereavement in childhood; the mourning process; anticipatory grief; psychoanalysis: mourning and trauma; children’s play and drawings as communication; and psychosocial therapeutic services. The thesis has particular relevance for child and adolescent psychotherapists and other mental health professionals who work within hospital and hospice settings.

The Political Economy of Reproduction: Motherhood, Work and the Home in Neoliberal Britain

This thesis investigates how the processes and practices of reproduction have been transformed not only by the ascendant political rationality of neoliberalism but also by women’s struggles that have reconfigured motherhood, the domestic home and the gendered organisation of employment. Through exploring both the 1970s feminist demand for “free 24- hour nurseries” and the contemporary provision of extended, overnight and flexible childcare, care that is often referred to as “24-hour childcare”, the research contributes to feminist understandings of the gendered and racialised class dynamics inside and outside the home and the wage. The research repositions the ‘Woman Question’ as, yet again unavoidable and necessary for comprehending and intervening in the brutalising consequences of capitalist accumulation. Situated within the Marxist feminist tradition, the work of reproduction is understood as a cluster of tasks, affective relations and employment that have historically been constructed and experienced as ‘women’s work’. The interrelation between the subjectivity of motherhood and the political economy of reproduction is analysed through a feminist genealogy of 24-hour childcare in Britain. Using ethnographic encounters, archival research and interview data with mothers and childcare workers, the research tells a story about the women who have worked both inside and outside the home, raised children, cooked and cleaned, and who, both historically and in the present, continue to create an immense amount of wealth and value. As women's labour market participation has steadily increased over the last 40 years, the discourse of reproduction has shifted to one in which motherhood is increasingly constructed as a choice. Within neoliberal discourse the decision to have a child is constructed as a private matter for which individuals bear the costs and responsibility. The thesis argues that, as a result of motherhood being constructed more and more as something that is chosen, the spaces of resistance and opposition towards motherhood have been limited and resistance has been individuated and privatised.
