The Third Hans Cloos Lecture. Urban landslides: socioeconomic impacts and overview of mitigative strategies 总被引:4,自引:0,他引:4
Robert L. Schuster Lynn M. Highland 《Bulletin of Engineering Geology and the Environment》2007,66(1):1-27
As a result of population pressures, hillsides in the world’s urban areas are being developed at an accelerating rate. This
development increases the risk for urban landslides triggered by rainfall or earthquake activity. To counter this risk, four
approaches have been employed by landslide managers and urban planners: (1) restricting development in landslide-prone areas;
(2) implementing and enforcing excavation, grading, and construction codes; (3) protecting existing developments by physical
mitigation measures and (4) developing and installing monitoring and warning systems. Where they have been utilized, these
approaches generally have been effective in reducing the risk due to landslide hazards. In addition to these practices, landslide
insurance holds promise as a mitigative measure by reducing the financial impact of landslides on individual property owners.
Until recently, however, such insurance has not been widely available and, where it is available, it is so expensive that
it has been little used.

Response to intervention (RTI) models for identifying learning disabilities rely on the accurate identification of children who, without Tier 2 tutoring, would develop reading disability (RD). This study examined 2 questions concerning the use of 1st-grade data to predict future RD: (a) Does adding initial word identification fluency (WIF) and 5 weeks of WIF progress-monitoring data (WIF-Level and WIF-Slope) to a typical 1st-grade prediction battery improve RD prediction? and (b) Can classification tree analysis improve the prediction accuracy compared to logistic regression? Four classification models based on 206 1st-grade children followed through the end of 2nd grade were evaluated. A combination of initial WIF, WIF-Level, and WIF-Slope and classification tree analysis improved prediction sufficiently to recommend their use with RTI.

The hypothesis that gender differences in children's adjustment is partially influenced by differences in temperament and interactions with same-sex peers was examined. Fifty-seven predominantly White, middle-class preschoolers (29 boys and 28 girls, M age?=?54.5 months) participated. Measures were taken of children's arousability, problem behaviors, and tendencies to play with same-sex peers. A semester later, children's peer status was assessed. Analyses revealed that arousability and same-sex peer play interacted to predict problem behaviors. For boys high in arousability, play with same-sex peers increased problem behaviors. In contrast, arousable girls who played with other girls were relatively unlikely to show problem behaviors. Moreover, the interaction of arousability and same-sex peer play predicted boys' (but not girls') peer status, and this relation was partially mediated by problem behaviors. The role of gender-related processes is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

A sample of 4,243 residents of Manchester and Newcastle-upon-Tyne, England, aged 50 to 93 yrs, completed the Beck Depression Inventory and a battery of 6 different cognitive tests. Beck scores were low, indicating gradations of dysphoria rather than clinical depression. Beck scores did not vary with age but were significantly higher for women than for men and for disadvantaged than for advantaged socioeconomic groups. Measures of fluid, but not of crystallized, ability declined as age increased. Socioeconomic disadvantage was associated with poorer performance on all cognitive tests. Men scored higher on a test of spatial reasoning, and women scored higher on a test of word definition and on 2 tests of verbal memory and learning. However, after variance associated with these demographic and individual difference variables was considered, and within a range indicative of dysphoria rather than clinical depression, higher Beck scores were associated with significantly poorer performance on both crystallized and fluid measures of cognitive ability. This association was less marked in women than in men, but age, socioeconomic advantage, and estimated lifetime intellectual ability did not act as protective or risk factors for vulnerability of cognitive processes to dysphoria.

One hundred twenty-one HIV-seropositive (HIV+) individuals and 85 seronegative controls performed a divided-attention task that engaged automatic and controlled attentional processing. Reaction times (RTs) to global and local targets that varied in probability were measured in 5 conditions. A neutral condition where global and local targets were equally probable was included as baseline. Participants showed expected tradeoffs in RTs as a function of target-level probability, with longer RTs to less probable targets and shorter RTs to more probable targets. However, the HIV+ group showed significantly greater costs compared with controls. Results are consistent with previous findings that HIV+ individuals are selectively impaired on tasks of controlled attentional processing, particularly under conditions of divided attention.

A survey of aircraft maintenance technicians with the Canadian Forces (N?=?157) found support for a model of burnout and occupational risk assessment. The model depicted employees' assessment of occupational risk as a function of the prevalence and lethalness of workplace hazards, as well as of the amount of control employees experience over their interactions with these hazards. A confirmatory factor analysis, in which LISREL analysis was used, supported an integrated model of risk perception and burnout. In this model, the employee's sense of control in managing occupational hazards was pivotal in both the experience of exhaustion and being at risk at work. Safety training contributed to perceived control and technicians' sense of effectiveness at work. The extension of the burnout construct beyond the human service domain was considered by using the Maslach Burnout Inventory—General Survey (C. Maslach, S. E. Jackson, & A. P. Leiter, 1996).

Network outsourcing is an alternative which through advanced technologies, standardization and a close partnership between the client corporation and provider, facilitates an effective and economical means of meeting present and future needs of various corporate user communities. Solutions typically consist of a wide array of services ranging from full operation of the network which includes assumption of assets and personnel to responsibility for various segments of the network such as Help Desk or Vendor Liaison functions. 相似文献

The authors used a Stroop negative priming paradigm to examine the effects of antipsychotic medication on selective attentional processes. The performance of 14 patients with schizophrenia who were withdrawn from neuroleptic medication was compared with that of 10 medicated patients and 16 matched controls. Results demonstrated an increase in negative priming to normal levels with neuroleptic therapy. In contrast, within-trial interference and facilitation effects appeared to be less sensitive to medication therapy. The sustainment of inhibitory processes over time may differentiate the inhibitory mechanisms of the medication-withdrawn patients from both the medicated patients and the matched controls. The study of sequential inhibitory processes and their response to neuroleptic treatment could be important methods for understanding the temporal parameters associated with inhibition in schizophrenia.
