The hot hand phenomenon in amateur golf : examination of psychological momentum : a thesis presented in partial fulfillment of the requirements for the degree of Master of Arts in Psychology at Massey University, Albany, New Zealand

This dissertation explored the notion of the hot hand phenomenon and psychological momentum in the sport of amateur golf within two separate but interrelated studies. Study one investigated the hot hand phenomenon with a sample of amateur golfers (N - 3238). Participant's hole-by-hole scores for rounds played over a two-year period were analysed. The results showed performance on a hole was influenced by prior performance for a greater number of golfers than would expected by chance, thus supporting the notion of the hot hand phenomenon. The results are discussed in relation to previous hot hand research. The aim of Study Two was to investigate reasons behind individual and gender differences in psychological momentum after an error. A selection of participants from study one were assigned to a negative momentum, negative facilitation, or no-momentum group, by virtue of how they tend to perform after an error and posted questionnaires measuring fear of failure, telic dominance, rumination, trait anxiety, self-confidence, perfectionism, and motivation orientation. The results suggest an individual's self-confidence, telic dominance, and task orientation influence ones performance after an error. These findings provide some supporting evidence for the Vallerand et al.'s (1988) antecedents-consequences psychological momentum model and Taylor and Demick's (1994) multidimensional model of momentum

Low thrust chemical orbit to orbit propulsion system propellant management study

Low thrust chemical propulsion systems were sized for transfer of large space systems from LEO to GEO. The influence of propellant combination, tankage and insulation requirements, and propellant management techniques on the LTPS mass and volume were studied. Liquid oxygen combined with hydrogen, methane or kerosene were the propellant combinations. Thrust levels of 445, 2230, and 4450 N were combined with 1, 4 and 8 perigee burn strategies. This matrix of systems was evaluated using multilayer insulation and spray-on-foam insulation systems. Various combinations of toroidal, cylindrical with ellipsoidal domes, and ellipsoidal tank shapes were investigated. Results indicate that low thrust (445 N) and single perigee burn approaches are considerably less efficient than the higher thrust level and multiple burn strategies. A modified propellant settling approach minimized propellant residuals and decreased system complexity, in addition, the toroid/ellipsoidal tank combination was predicted to be shortest

Ambient interaction and situational influence: case studies in public sites.

An audience's direct physical intervention is widely believed to be instrumental in the field of interactive art. However, this long established expectation faces new challenges through the increasing accessibility of a growing diversity of interactive technologies and ubiquitous smart media. Such innovations are often fully integrated components of interactive public artworks, many of which do not directly involve audiences or individuals as key agents in the functional or aesthetic realisation of the work. Based on three case studies of interactive artworks in public places, this article identifies an important characteristic of interactivity in interactive art, through the largely unexplored concept of 'Ambient Interaction' in which artworks are embodied and enacted through environmental conditions and situational influences rather than exclusively through people's intentional and direct physical engagement

Platelet count and transfusion requirements during moderate or severe postpartum haemorrhage

Limited data exist on platelet transfusion during postpartum haemorrhage. We retrospectively analysed a consecutive cohort from a single centre of 347 women with moderate or severe postpartum haemorrhage, transfused according to national guidelines. Twelve (3%) women required a platelet transfusion. There were no differences between women who did and did not receive platelets with respect to age, mode of initiation of labour or mode of delivery. Women receiving a platelet transfusion had a lower median (IQR [range]) platelet count at study entry than women who did not receive platelets before haemorrhage (135 (97–175 [26–259])×109.l−1 vs 224 (186–274 [91–1006])×109.l−1), respectively), and at diagnosis of postpartum haemorrhage (median 114 (78–153 [58–238])×109.l−1 vs 193 (155–243 [78–762])×109.l−1 respectively). Six women were thrombocytopenic pre-delivery. The cause of haemorrhage that was associated with the highest rate of platelet transfusion was placental abruption, with three of 14 women being transfused. If antenatal thrombocytopenia or consumptive coagulopathy were not present, platelets were only required for haemorrhage > 5000 ml. Early formulaic platelet transfusion would have resulted in many women receiving platelets unnecessarily. Using current guidelines, the need for platelet transfusion is uncommon without antenatal thrombocytopenia, consumptive coagulopathy or haemorrhage > 5000 ml. We found no evidence to support early fixed-ratio platelet transfusion

Evaluating bilingual peer support for breastfeeding in a local Sure Start

In Tower Hamlets, the Bangladeshi women have a very low rate of breastfeeding and the difference between their intentions to breastfeed and actually breastfeeding is far wider than for women from other ethnic groups. In Bangladesh, breastfeeding is well rooted in its own traditional culture. A Sure Start local programme funded a Bangladeshi support worker to work with childbearing Bangladeshi women in the area; many of who are not fluent in English. A short evaluation of this work was conducted to assess the impact of bilingual breastfeeding support to women’s uptake and duration of breastfeeding. The majority of women found the support worker to be the most helpful breastfeeding advisor and felt she influenced them to breastfeed. Despite this, a minority of women exclusively breastfed and most reported having problems feeding during hospital stay. This evaluation highlighted the need for further work in this area
