Evaluation of salmon and steelhead spawning habitat quality in the South Fork Trinity River Basin, 1997

Sediment sampling was used to evaluate chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss) spawning habitat quality in the South Fork Trinity River (SFTR) basin. Sediment samples were collected using a McNeil-type sampler and wet sieved through a series of Tyler screens (25.00 mm, 12.50 mm, 6.30 mm, 3.35 mm, 1.00 mm, and 0.85 mm). Fines (particles < 0.85 mm) were determined after a l0-minute settling period in Imhoff cones. Thirteen stations were sampled in the SFTR basin: five stations were located in mainstem SFTR between rk 2.1 and 118.5, 2 stations each were located in EF of the SFTR, Grouse Creek, and Madden Creek, and one station each was located in Eltapom and Hayfork Creeks. Sample means for fines(particles < 0.85 mm) fer SFTR stations ranged between 14.4 and 19.4%; tributary station sample mean fines ranged between 3.4 and 19.4%. Decreased egg survival would be expected at 4 of 5 mainstem SFTR stations and at one station in EF of SFTR and Grouse Creek where fines content exceed 15%. Small gravel/sand content measured at all stations were high, and exceed levels associated with reduced sac fry emergence rates. Reduction of egg survival or sac fry emergence due to sedimentation in spawning gravels could lead to reduced juvenile production from the South Fork Trinity River. (PDF contains 18 pages.

Quality Indicators Guiding Secondary Career and Technical Education Programs of Study

The purpose of this study was to examine quality indicators currently guiding the rigor of secondary career and technical education (CTE) programs of study in the United States. Quality indicators are desirable characteristics or expectations for a comprehensive and effective CTE program of study. As of May 2017, we were able to locate publicly accessible secondary CTE quality program standards/guidelines for 38 states. A majority (n=24) updated their secondary CTE quality program standards/guidelines within the last five years (i.e., 2012-2017). Deductive content analysis was conducted to examine the 38 state profiles using the Association of Career and Technical Education (ACTE) Quality CTE Program of Study Framework 4.0 for coding purposes. Common quality elements and key quality indicators were identified from those state documents, which supplements the ACTE Framework. Implications and examples for practice are also discussed

Preparing for Industrial Collaborative Robots: A Literature Review of Technology Readiness and Acceptance Models

This item is only available electronically.Collaborative robots (cobots) are an emerging technology that are increasingly being introduced into organisations. However, research investigating employee attitudes towards, or assessment of factors predicting acceptance of cobots is limited. A literature review was conducted to identify reliable and parsimonious models of technology acceptance that would hold relevance when applied to cobots. Understanding and facilitating employee acceptance of such technology is important if the improved productivity, job satisfaction and cost savings associated with its implementation are to be achieved. The Technology Readiness Index (Parasuraman, 2000) and Technology Acceptance Model (Davis, 1989) were considered most appropriate as a starting point to empirically explore cobot acceptance.Thesis (M.Psych(Organisational & Human Factors)) -- University of Adelaide, School of Psychology, 201

Predicting independent functioning in an elderly population: the evaluation of working memory capacity as a biomarker of ageing.

The ageing process is characterised by declines in physical and cognitive ability and by a general increase in dependence in carrying out daily tasks. Maintenance of functional independence is critical to quality of life in elderly populations (Black & Rush, 2002; Sulander et al., 2005). Therefore, identifying measures that can predict functional ability is of particular interest to societies with an ageing population. Due to increases in inter-individual and intra-individual variability with age, chronological age has been demonstrated to be a poor predictor of an individual's functional ability (Bauco et al, 1996; Willis et al., 1992). Consequently, other, more successful indicators, referred to as biomarkers, have been established (e.g. grip strength and visual acuity). However, of these more accurate measures, few are cognitive. This is surprising given the reported strong and positive relationship between independent functioning and intact cognition (Atkinson et al.,2005; Bäckman & Hill, 1996). Therefore, the current project investigated whether a task of working memory capacity (Reading Span), could predict a range of independent functioning outcome measures. Employing a longitudinal study design (three measurement occasions over approximately 18 months), 150 community-dwelling participants, 70 years of age and over (99 females, 51 males), were tested on a range of cognitive and physiological tasks. Cross-sectional results from logistic and linear regressions showed that chronological age was in fact a significant predictor of all three functional outcome measures. In contrast, Reading Span was a significant predictor only of one outcome measure (reasoning ability). Some of the physiological and sensorimotor biomarkers were found to predict two of the three functional outcome measures. Therefore, cross-sectional results showed that all of the biomarkers were limited in their ability to predict outcomes measured concurrently and, in the current sample, chronological age was the best predictor of some outcome measures. However, over time, Reading Span became a significant predictor of most of the outcome measures and explained a comparable amount of variance to age. Reading Span also often accounted for more variance than physiological and sensorimotor variables. The current sample was healthy, independent functioning and cognitively intact. Performance variability was low initially and was further reduced by the presence of selective attrition (i.e. individuals with poorer reasoning and crystallised ability and lesser working memory capacity dropped out of the study). Based on this, it is not surprising that biomarkers were able to explain less than 10% of the variance in any outcome measure. In summary, the current study shows that working memory capacity, as measured by Reading Span, is a valuable addition to the assessment of functional ability in an elderly population and highlights the importance of cognition in this context. However, further investigations are required before Reading Span can be described as a biomarker of ageing.Thesis (Ph.D.) -- University of Adelaide, School of Psychology, 200

Review of Norma González, Luis C. Moll, Cathy Amanti (eds.), \u3cem\u3eFunds of Knowledge: Theorizing Practices in Households, Communities and Classrooms\u3c/em\u3e

This quote, which opens Chapter 2 of González et al.\u27s edited collection targeted at teachers and their educators, captures both the spirit and the promise of this volume on Funds of Knowledge research. Many readers are likely familiar with this research tradition, which invites educators outside the walls of the classroom to encounter the rich and varied cultural resources within their students\u27 communities in order to foster educators\u27 understanding of these resources as strengths rather than as cultural or cognitive deficits. The authors of these pieces are teachers, teacher educators and researchers, who explore their personal and professional journeys as they, in Bateson\u27s (2000: 81) words, \u27crossed the lines of strangeness\u27 during this multi-year, multi-sited ethnographic project documenting and theorising their students\u27 cultural histories and practices, and seeking ways to incorporate those cultural resources into their classrooms

Moving Beyond Consultation And Into Action With A Client Project

Attempting to implement client-based projects within a single semester often overwhelms students and underwhelms the client and grading professor. In this paper, we share results from a two-year pilot project in which the components of a client project were split between several classes. We discuss the client project model as a valuable teaching method that allows students to implement and reflect on marketing strategies. We show that by dividing the project across several teams, the project becomes more manageable and valuable for students and professors.  In comparison to other common projects, the client project presented here produced substantial and valuable outcomes for the non-profit client while providing students the unique experience of working in a multiple team structure.  We indicate that this approach may be useful for select marketing classes

An Examination Of Trust In Contemporary American Society

It is hard to imagine a society functioning in the absence of trust. From the smallest incident—crossing the street when the light is green—to the most consequential events—a government fulfilling its pledge to pay Social Security—individuals must be able to rely on individuals and institutions to behave in a reliable and trustworthy manner. When trust is absent, chaos ensues. Of course, trust should not be given blindly; authentic trust needs to be earned and renewed (Fukuyama, 1995; Putnam, 2000)

The Dysexecutive Questionnaire Revised (DEX-R): An extended measure of everyday dysexecutive problems after acquired brain injury.

The Dysexecutive Questionnaire (DEX) is a tool for measuring everyday problems experienced with the dysexecutive syndrome. This study investigated the psychometric properties of a revised version of the measure (DEX-R), a comprehensive tool, grounded in current theoretical conceptualisations of frontal lobe function and dysexecutive problems. The aim was to improve measurement of dysexecutive problems following acquired brain injury (ABI). Responses to the DEX-R were collected from 136 men and women who had experienced an ABI (the majority of whom had experienced a stroke or subarachnoid haemorrhage) and where possible, one of their carers or family members (n = 71), who acted as an informant. Rasch analysis techniques were employed to explore the psychometric properties of four newly developed, theoretically distinct subscales based on Stuss model of frontal lobe function and to evaluate the comparative validity and reliability of self and informant ratings of these four subscales. The newly developed subscales were well targeted to the range of dysexecutive problems reported by the current sample and each displayed a good level of internal validity. Both self- and independent-ratings were found to be performing reliably as outcome measures for at least a group-level. This new version of the tool could help guide selection of interventions for different types of dysexecutive problems and provide accurate measurement in neurorehabilitation services.National Institute for Health ResearchThis is the author accepted manuscript.

Teaching Character Education to Students with Behavioral and Learning Disabilities through Mentoring Relationships

Despite nation-wide efforts to implement character education programs in schools, there is no research that specifically examines the effectiveness of these programs on students with behavioral and learning disabilities. SO (Service-Learning Opportunities) prepared for citizenship, an inclusive after school program, was designed to enhance the character development of elementary students by teaching specific character traits including: (1) responsibility and self-control; (2) cooperation and teamwork; and (3) respect and appreciation of diversity through language arts and other activities. The program relies on high school and college mentors to introduce the curriculum to the children and build friendships. In this ethnographic study, we examine participants’ knowledge of the curriculum and perceptions of the program. Data gathered from in-depth ethnographic interviews of 19 students with behavioral and other learning and language disabilities were coded through domain analysis. Descriptive statistics are included. Results indicate that students with disabilities: (1) expressed responsibilities for their actions; (2) responded to the ideas of cooperation and teamwork and respect and appreciation of diversity; (3) learned to make new friends; and (4) found learning about character to be fun and rewarding

The Kepler-454 System: A Small, Not-rocky Inner Planet, a Jovian World, and a Distant Companion

Kepler-454 (KOI-273) is a relatively bright (V = 11.69 mag), Sun-like star that hosts a transiting planet candidate in a 10.6 day orbit. From spectroscopy, we estimate the stellar temperature to be 5687 ± 50 K, its metallicity to be [m/H] = 0.32 ± 0.08, and the projected rotational velocity to be v sin i 10 years and mass >12.1 MJ. The 12 exoplanets with radii <2.7 R_⊕ and precise mass measurements appear to fall into two populations, with those <1.6 R_⊕ following an Earth-like composition curve and larger planets requiring a significant fraction of volatiles. With a density of 2.76 ± 0.73 g cm^(−3), Kepler-454b lies near the mass transition between these two populations and requires the presence of volatiles and/or H/He gas
