- ItemImpact of a handicapped child on mental health of parents(B M J PUBLISHING GROUP, 1986-11-29) Romans-Clarkson SE; Clarkson JE; Dittmer ID; Flett R; Linsell C; Mullen PE; Mullin BIn a cross sectional study the mental health of parents of physically and mentally handicapped preschool children was compared with that of parents of healthy preschool children. The social networks of the parents with handicapped children were also studied to determine factors that might influence psychiatric morbidity. The mothers of the handicapped children showed significantly more psychiatric morbidity than the control mothers, but the fathers did not show the same deleterious effect on mental health.

- ItemThe value of the world's ecosystem services and natural capital(Nature publishing group, 1997-05-15) Costanza R; d'Arge R; de Groot R; Faber S; Grasso M; Hannon B; Limburg K; Naeem S; O'Neill RV; Paruelo J; Raskin RG; Sutton P; van den Belt MThe services of ecological systems and the natural capital stocks that produce them are critical to the functioning of the Earth’s life-support system. They contribute to human welfare, both directly and indirectly, and therefore represent part of the total economic value of the planet. We have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations. For the entire biosphere, the value (most of which is outside the market) is estimated to be in the range of US$16–54 trillion (1012) per year, with an average of US$33 trillion per year. Because of the nature of the uncertainties, this must be considered a minimum estimate. Global gross national product total is around US$18 trillion per year.
- ItemEroded porous-media aquifer controlled hydrovolcanic centers in the South Lake Balaton region, Hungary: The Boglar volcano(Akad�miai Kiad�, 1999) Nemeth K; Martin U; Philippe MThe volcanic centers next to Balatonboglar township represent 3.5 Ma old products of post-extensional alkaline basaltic volcanism in the Pannonian Basin (eastern Central Europe). They are small, eroded volcanic centers located on the southern shore of Lake Balaton and genetically related to the Bakony-Balaton Highland Volcanic Field eruptive centers. The relatively small area (500 m x 500 m) contains at least 2 eruptive centers, which are probably related to each other and have built up a complex volcano, called the Boglar Volcano. The volcanic rocks overlie the older Pannonian clastic sedimentary sequence and represent the topographic highs in this area. The areas of lower elevation around the eruptive centers are covered by Pleistocene to Holocene swamp, lake and river clastic sediments, which strongly suggest intense erosion during the last few million years. All volcanic rocks around Balatonboglar are volcaniclastic. There is no evidence of lava flow occurrence. The volcaniclastic sediments have been divided into two lithofacies associations. The largest amount of volcaniclastic rocks is located in the center of the local hills and has been interpreted as a phreatomagmatic crater fill lapilli tuff. They contain large amphibole megacrysts and small olivine crystals. The second lithofacies association is interpreted as lahar deposits. This sequence contains an unusually large amount of fossil tree trunks, which are identified as Abies species. Within a small area in the western hills small outcrops show evidence of maar-lake clastic sediment occurrence. On the hilltops debris shows intimate interaction processes between clastic sediments and basaltic melt. We interpret this to mean that the eruptive centers of Boglar Volcano were formed under subaerial conditions, with explosions fueled by intensive interaction between water-saturated Pannonian sand and uprising basaltic magma.
- ItemLate miocene paleo-geomorphology of the bakony-balaton highland volcanic field (Hungary) using physical volcanology data(Gebruder Borntraeger, 1999) Nemeth K; Martin UA new view is presented of the Bakony-Balaton Highland Volcanic Field (BBHVF), Hungary, active in late Miocene and built up of ca. 100 mostly alkaline basaltic eruptive centers, scoria cones, tuff rings, maar volcanic complexes and shield volcanoes. A detailed map shows the physical volcanology of the monogenetic volcanic field. In areas where thick Pannonian Sandstone beds build up the pre-volcanic strata normal maar volcanic centers have formed with usually thick late magmatic infill in the maar basins. In areas, where relatively thin Pannonian Sandstone beds resting on thick Mesozoic or Paleozoic fracture-controlled, karstwater-bearing aquifer, large unusual maar volcanic sequences appear (Tihany type maar volcanoes). In the northern part of the field large former scoria cones and shield volcanoes give evidence for a smaller impact of the ground and surface water causing phreatomagmatic explosive activity. The Tihany type maar volcanic centers are usually filled by thick maar lake deposits, building up Gilbert type gravelly, scoria rich deltas in the northern side of the maar basins, suggesting a mostly north to south fluvial system in the pre-volcanic surface. Calculating paleosurface elevation for the eruptive centers, two paleo-geomorphology maps are drawn for a younger (4-2.8 Ma) and an older (7.54-4 Ma) scenario. The erosion rate of the volcanic field is estimated to vary between 96 m/Ma and 18 m/Ma. In the western site of BBHVF the erosion rate is higher (more than 60 m/Ma, Tapolca Basin), and an average 50 m/Ma in the center and eastern side.
- ItemDairy deregulation and low-input dairy production: A bioeconomic evaluation(Western Agricultural Economics Association, 1999) Tozer PR; Huffaker RGDeregulation of the Australian dairy industry could affect the utilization of resources by milk producers and the profitability of dairy production. In this study we examine the feed mix that dairy producers use, both pastures and supplements, under partial and total deregulation. We are particularly interested in the interaction of pasture utilization and farm profitability. The results of this research demonstrate that profitable low-input dairying is constrained by the most limiting resource, feed supplied by pasture, and that the interactions between economic and biological processes are critical to farm profitability.

- ItemModular neural network modelling for long-range prediction of an evaporator(2000) Russell NT; Bakker HH; Chaplin RIThis paper presents the development of a modular neural network model of a three-effect, falling-film evaporator. The model comprises a number of sub-networks each modelling a specific element of the overall system. The modular structure was employed in order to provide benefits in terms of improved model training and performance. The performance of the modular neural model is demonstrated for long-range prediction by comparing it with process data, an analytical simulation and a linear ARX model. The results show that the modular neural model can satisfactorily predict over a horizon of arbitrary length and is suited for implementation within a predictive control scheme. Benefits in terms of model flexibility and interpretability are also discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
- ItemEnterprising behaviour of ordinary people(Psychology Press, 2000) Van Gelderen, MarcoStarting out with the idea that everybody is in principle capable of enterprising behaviour, the concept of enterprise is applied to non-business people as well as business people. A random sample of people is asked to furnish an example of enterprising behaviour that they have shown themselves. Further, they are asked what is enterprising about this behaviour. The results show that in different realms of enterprising behaviour different dimensions of enterprise are mentioned. For example, people giving an example from their leisure time regard merely being active as enterprising, employees mention risky elements in their work, business owners emphasize autonomy, and students regard it as enterprising that they work for their professional or personal development. So people can be enterprising in different areas of life and in different manners. Obtaining a domain of enterprising behaviours and dimensions is a first step in constructing a scale of ''enterprising behaviour of ordinary people''.
- ItemStrategies, uncertainty and performance of small business startups(Kluwer, 2000) Van Gelderen, Marco; Frese, Michael; Thurik, RoyPersonal strategies of owners/founders of small business startups are related to performance and to environmental uncertainty. This is done using a longitudinal data set. Personal strategies are operationalized by a behavioral measure of the manners in which small business founders deal with situations. The results suggest a dynamic process between strategy and performance. Business owners that perform poorly employ a Reactive Strategy, with poor performance leading to increased use of reactive behavior. High performing business owners start out focussing on the most crucial issues (Critical Point Strategy), with high performance leading to a more top-down (Complete Planning) approach. These relations are controlled for characteristics of the environment of the firm. Strategy use is dependent upon the type and level of environmental uncertainty. Complete Planning strategy is used less frequently in a fast changing environment and more often in a complex environment. Use of Opportunistic Strategy is negatively related to the complexity of the environment, while the Reactive Strategy is used more frequently in a non-munificent environment.
- ItemDomestic violence, psychological distress, and physical illness among New Zealand women: Results from a community-based study(New Zealand Psychological Society, 2000) Kazantzis N; Flett RA; Long NR; MacDonald C; Millar MThis study aimed to measure the prevalence of psychological distress and physical illness among women in New Zealand, and to identify the risk factors for psychological distress and health, with specific reference to domestic violence. A survey was carried out among a community sample of 961 women aged 19-90 years. Among all women surveyed, 25% were classified as experiencing psychological distress at the time of interview, 22% were classified as experiencing severe symptoms of physical illness, and 17% reported domestic violence by a family member at some point in their lives. Among those women who had experienced domestic violence, the perception that their life was in serious danger and the impact of the violence on their life each contributed significantly to variability in psychological distress (22% variance accounted). An estimated 12% of all cases of psychological distress and 7% of all cases of serious physical illness were attributable to domestic violence. The study underscores the need to improve policy for mental and physical health screening and care for abused women within health services in New Zealand.
- ItemContribution of retirement-related variables to well-being in an older male sample(New Zealand Psychological Society, 2000) Alpass FM; Neville S; Flett RAWith New Zealand's increasing older adult population comes an increase in the number of retirees. Changes in work patterns, earlier retirement and increasing life expectancy are resulting in longer periods of time spent in retirement. The effects of retirement on health and well-being have been viewed both positively and negatively and previous research on the impact of retirement has been equivocal. Inconsistencies may be attributable to a number of factors including time since retirement, changes in health status of the retiree, loss of social supports, policies of voluntary versus mandatory retirement and whether the work career was satisfying versus unfulfilled. Further, there are many possible outcomes following retirement and indices such as depression, and psychological well-being may be influenced by retirement in different ways. The present study sought to address a number of these issues by investigating the relative contribution of demographic, health, social support and retirement related variables to a number of indices of well-being in a group of retired older adult males. The present study found the nature of retirement (forced/voluntary) was unrelated to well-being outcomes; number of years retired was negatively associated with well-being outcomes; and prior job satisfaction was positively related to well-being outcomes. However, retirement variables contributed little to the overall explained variance in well-being indices. The major contributors to outcomes were diagnosis of a long-term illness or disability and satisfaction with social supports. Findings are discussed in relation to the literature.
- ItemThe Szigliget maar/diatreme, Bakony- Balaton Highland Volcanic Field (Hungary)(Massey University., 2000-01-01) Nemeth, Karoly; Korbely, Barnabas; Karatson, DavidA preliminary volcanological mapping has been carried out in the western part of the Bakony- Balaton Highland Volcanic Field (BBHVF) around Szigliget (Hungary) village. Pyroclastic rocks have been found building up the three distinct hillsides in the area. The pyroclastic rock beds in each hillside show similar north-westward dip direction and similar textural and compositional characteristics, suggestive of a complex but closely related volcanic system in the area. The pyroclastic deposits have been grouped into three units according to their textural, compositional and stratigraphic characteristics. Unit 1 which represents the lowermost stratigraphic position crops out in the southern side of the study area. It consists of coarse-grained, matrix-supported massive to weakly bedded, accidental lithic clast-rich, block-bearing lapilli tuffs / tuff breccias, extremely rich in deep-seated accidental lithic and peridotite lherzolite clasts. Unit 2 which represents an intermediate stratigraphic position crops out in the southern and north-east hilltops. It consists of coarse-grained accidental lithic clast-rich, normal graded, bedded, vitric lapilli tuffs / tuff beds. Deep-seated accidental lithic clasts are common, but large peridotite lherzolite fragments are relatively rare. Unit 3 which represents the highest stratigraphic position in the area crops out in the northwestern side. It consists of fine-to-coarse grained, bedded, accidental lithic clast-rich vitric lapilli tuff / tuff beds. Deep-seated lithic clasts as well as peridotite lherzolite fragments are rare. Accidental lithic clasts, derived from shallow prevolcanic strata (Neogene sediments), have a dominant proportion of pyroclastic rocks in this unit. In each unit the volcanic glasses are angular, non- to highly vesiculated tephrite to phono-tephrite shards. The presence of sideromelane glass shards and the large amount of accidental lithic clasts in beds from each units indicate subsurface phreatomagmatic explosive processes during formation of pyroclastic rocks at Szigliget. The pyroclastic rocks are interpreted as part of a former crater rim deposits around maar basin which subsequently subsided inward into a vent. Unit 1 is interpreted to be a lower diatreme deposit and Unit 2 and Unit 3 a series of near-vent pyroclastic density currents and fallout tephra.
- ItemExperimental study of contact transition control incorporating joint acceleration feedback(Institute of Electrical and Electronics Engineers, 2000-09) Xu, W. L.; Han, J. D.; Tso, S. K.Joint acceleration and velocity feedbacks are incorporated into a classical internal force control of a robot in contact with the environment. This is intended to achieve a robust contact transition and force tracking performance for varying unknown environments, without any need of adjusting the controller parameters, A unified control structure is proposed for free motion, contact transition, and constrained motion in view of the consumption of the initial kinetic energy generated by a nonzero impact velocity. The influence of the velocity and acceleration feedbacks, which are introduced especially for suppressing the transition oscillation, on the postcontact tracking performance is discussed. Extensive experiments are conducted on the third joint of a three-link direct-drive robot to verify the proposed scheme for environments of various stiffnesses, including elastic (sponge), less elastic (cardboard), and hard (steel plate) surfaces. Results are compared with those obtained by the transition control scheme without the acceleration feedback. The ability of the proposed control scheme in resisting the force disturbance during the postcontact period is also experimentally investigated.
- ItemCombined injection of rAAV with mannitol enhances gene expression in the rat brain(Cell Press, 2000-09-06) Mastakov M; Baer K; Xu R; Fitzsimons H; During MRecombinant adeno-associated viruses (rAAV) are highly efficient vectors for gene transfer into the central nervous system (CNS). However, a major hurdle for gene delivery to the mammalian brain is to achieve high-level transduction in target cells beyond the immediate injection site. Therefore, in addition to improvements in expression cassettes and viral titers, optimal injection parameters need to be defined. Here, we show that previous studies of somatic cell gene transfer to the mammalian brain have used suboptimal injection parameters, with even the lowest reported perfusion rates still excessively fast. Moreover, we evaluated the effect of local administration of mannitol to further enhance transgene expression and vector spread. Ultraslow microperfusion of rAAV, i.e., <33 nl/min, resulted in significantly higher gene expression and less injury of surrounding tissue than the previously reported rates of 100 nl/min or faster. Co-infusion of mannitol facilitated gene transfer to neurons, increasing both the total number and the distribution of transduced cells by 200-300%. Gene transfer studies in the CNS using rAAV should use very slow infusion rates and combined injection with mannitol to maximize transduction efficiency and spread.
- ItemStudies of the microstructure of polymer-modified bitumen emulsions using confocal laser scanning microscopy(BLACKWELL SCIENCE LTD, 2001) Forbes A; Haverkamp RG; Robertson TR; Bryant JR; Bearsley SPolymer-modified bitumen emulsions present a safer and more environmentally friendly binder for enhancing the properties of roads. Cationic bitumen emulsion binders containing polymer latex were investigated using confocal laser scanning microscopy. The latex was incorporated into the bitumen emulsion by using four different addition methods and all emulsions were processed with a conventional colloid mill. The emulsion binder films were studied after evaporation of the emulsion aqueous phase. We show how the microstructure and distribution of the polymer varies within the bitumen binder depending on latex addition method, and that the microstructure of the binder remains intact when exposed to elevated temperature. It was found that a distinctly fine dispersion of polymer results when the polymer is blended into the bitumen before the emulsifying process (a monophase emulsion). In contrast, bi-phase emulsion binders produced by either post-adding the latex to the bitumen emulsion, or by adding the latex into the emulsifier solution phase before processing, or by comilling the latex with the bitumen, water and emulsifier all resulted in a network formation of bitumen particles surrounded by a continuous polymer film. The use of emulsified binders appears to result in a more evenly distributed polymer network compared to the use of hot polymer-modified binders, and they therefore have greater potential for consistent binder cohesion strength, stone retention and therefore improved pavement performance.
