Use of a structured investigative protocol enhances young children's responses to free-recall prompts in the course of forensic interviews.

One hundred alleged victims of child sexual abuse (ages 4–12 years; M?=?8.1 years) were interviewed by police investigators about their alleged experiences. Half of the children were interviewed using the National Institute of Child Health and Human Development's structured interview protocol, whereas the other children—matched with respect to their age, relationship with the alleged perpetrator, and seriousness of the alleged offenses—were interviewed using standard interview practices. Protocol-guided interviews elicited more information using open-ended prompts and less information using option-posing and suggestive questions than did standard interviews; there were no age differences in the amount of information provided in response to open-ended invitations. In 89% of the protocol interviews, children made their preliminary allegations in response to open-ended prompts, compared with 36% in the standard interviews.

A Knowledge Modeling Approach to Evaluating Student Essays in Engineering Courses

Automatically grading essay questions can have advantages for instructors in higher education. Understanding and specifying how grading is done manually, so that there is potential to do it automatically, is a labor‐intensive effort in knowledge elicitation, acquisition, and representation. This paper describes how an interdisciplinary team used conceptual graphs to formally specify the model for a good essay response, and then how that expert model was used as the standard by which the student responses were judged. The methodology is then described for creating the expert model for student responses. These were compared using two different approaches. It was found that most students included the most important concepts, but those student answers that were more complete (i.e., also including concepts of lesser importance) received higher grades. The approaches are then evaluated in terms of reliability and validity, and finally, suggestions are made for future work.     

A longitudinal study of grade retention: Academic and behavioral outcomes of retained students through adolescence.

Most research examining the efficacy of early grade retention has been limited to outcomes during elementary school. A notable gap in the retention literature is the dearth of studies examining outcomes during late adolescence. The results of this prospective longitudinal study include comparisons among four unique samples: (1) early grade retainees; (2) students retained in a transition classroom; (3) students recommended for transitional placement but promoted; and (4) regularly promoted students, through the eleventh grade. Results of this study failed to demonstrate the effectiveness of grade retention on academic achievement. Moreover, analyses of behavior suggest that retained students display more aggression during adolescence. Furthermore, the group of students recommended for transitional placement, but promoted, were comparable to the control group on all achievement and behavior measures during high school. The results of this study may be further understood considering a transactional model of development, emphasizing the importance early experiences on subsequent development. The results of longitudinal studies of grade retention warrant further consideration in developing educational policies and implementing effective prevention and early intervention strategies.

Reduced specificity of autobiographical memory and depression: The role of executive control.

It has been widely established that depressed mood states and clinical depression, as well as a range of other psychiatric disorders, are associated with a relative difficulty in accessing specific autobiographical information in response to emotion-related cue words on an Autobiographical Memory Test (AMT; J. M. G. Williams & K. Broadbent, 1986). In 8 studies the authors examined the extent to which this relationship is a function of impaired executive control associated with these mood states and clinical disorders. Studies 1-4 demonstrated that performance on the AMT is associated with performance on measures of executive control, independent of depressed mood. Furthermore, Study 1 showed that executive control (as measured by verbal fluency) mediated the relationship between both depressed mood and a clinical diagnosis of eating disorder and AMT performance. Using a stratified sample in Study 5, the authors confirmed the positive association between depressed mood and impaired performance on the AMT. Studies 6-8 involved experimental manipulations of the parameters of the AMT designed to further indicate that reduced executive control is to a significant extent driving the relationship between depressed mood and AMT performance. The potential role of executive control in accounting for other aspects of the AMT literature is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Seeing Black: Race, Crime, and Visual Processing.

Using police officers and undergraduates as participants, the authors investigated the influence of stereotypic associations on visual processing in 5 studies. Study 1 demonstrates that Black faces influence participants' ability to spontaneously detect degraded images of crime-relevant objects. Conversely, Studies 2-4 demonstrate that activating abstract concepts (i.e., crime and basketball) induces attentional biases toward Black male faces. Moreover, these processing biases may be related to the degree to which a social group member is physically representative of the social group (Studies 4-5). These studies, taken together, suggest that some associations between social groups and concepts are bidirectional and operate as visual tuning devices--producing shifts in perception and attention of a sort likely to influence decision making and behavior.

Edible table (bio)spread containing potentially probiotic Lactobacillus and Bifidobacterium species

A prototype of a reduced fat (60% w/w) edible table biospread, with an added viable, nongrowing, mixed-strain and potentially probiotic culture was developed. Conventional commercial aqueous-phase ingredient and reduced fat spread processing technologies were modified to achieve acceptable strain viability ( ≥   10⁵ cfu/mL) during scraped-surface heat exchange emulsion processing and biospread shelf life. The modifications consisted of:

• 1

   spilt-stream pasteurization of the aqueous and lipid phases (thereby obviating the need for in-line pasteurization of the water-in-oil emulsion during processing);

       

Statistical,economic and other tools for assessing natural aggregate

Quantitative aggregate resource assessment provides resource estimates useful for explorationists, land managers and those who make decisions about land allocation, which may have long-term implications concerning cost and the availability of aggregate resources. Aggregate assessment needs to be systematic and consistent, yet flexible enough to allow updating without invalidating other parts of the assessment. Evaluators need to use standard or consistent aggregate classification and statistic distributions or, in other words, models with geological, geotechnical and economic variables or interrelationships between these variables. These models can be used with subjective estimates, if needed, to estimate how much aggregate may be present in a region or country using distributions generated by Monte Carlo computer simulations.

Online recruiting: The effects of organizational familiarity, website usability, and website attractiveness on viewers’ impressions of organizations

Previous research on Internet recruitment has made the implicit assumption that recruitment websites influence viewers’ opinions of recruiting organizations. This study tested this assumption using a pretest/posttest design. Findings revealed that participants’ organizational favorability, image as employer, and organizational attractiveness perceptions were affected by their viewing of organizational recruitment websites. Greater increases in favorable organizational evaluations from the pretest measures to the posttest measures occurred with organizations maintaining websites that were easy to navigate and/or that were appealing. Contrary to predictions made by signaling theory, recruitment websites had similar effects on the organizational impressions of all individuals, regardless of their familiarity with the organizations maintaining the recruitment websites that they viewed.     

Limnological characteristics, eutrophication and cyanobacterial blooms in an inland reservoir, Australia

Ben Chifley Reservoir, the only potable water supply for Bathurst, New South Wales, Australia, has been experiencing recurrent cyanobacterial bloom problems since 1991. A study was undertaken from June 1998 to July 1999 to assess the limnological characteristics pertinent to eutrophication and the associated cyanobacterial blooms. From January–May 1999, the reservoir exhibited significant numbers of cyanobacterial cells, totalling > 9000 cells mL^?1. The highest number of cells (> 27 000 cells mL^?1) was recorded during April 1999. The water quality characteristics of the reservoir, and the river inflow and climatic data, were grouped into three distinct periods; before, during and after cyanobacterial blooms. High water temperature (15–22°C), thermal stratification (ΔT = 2.7–2.8°C), depletion of dissolved oxygen and high nutrient concentrations, all of which are conducive to enhanced cyanobacterial blooms, were evident before and during the bloom periods. Based on its nitrogen to phosphorus molar ratio, Ben Chifley Reservoir can be considered as being phosphorus‐deficient, in contrast to nitrogen, which is readily available from a number of sources in its drainage basin, including atmospheric fixation. Thus, it is recommended that adopting management strategies to reduce the quantity of bioavailable phosphorus in the reservoir would be the most effective way to minimize the occurrence of algal blooms.
