Back health: development of a risk assessment tool.

Back injuries are one of the most significant industrial liabilities, resulting in increased absenteeism, costly medical expenses, and often employee disability. The authors present a reliable and valid back health risk assessment tool to measure predisposition for back injuries. The tool was developed with the collaboration of members of a local constituent association. The tool can be implemented by routine interviews with workers. Occupational health nurses can use the tool to diagnose and possibly alleviate back injuries in workers. Use of the tool will help to further define the characteristics for the potential for back injury.

New tools for laboratory design and management.

The clinical laboratory is changing from a place of activity based on sample analysis to an in vitro diagnostic network. To convince our team, partners, and administrators, we need new comprehensive tools to define a strategy with limited risk of failure or conflicts. Specific quality goals should be established before choosing automated tools for sample handling, analytical systems, laboratory information systems, communication systems, or advanced technologies. A system approach maps and simplifies the process, based more on a functional study than on classical disciplines. A customer-supplier approach establishes the requirements between partners either inside or outside the laboratory. The quality system must be a management tool, linking samples, tasks, information, and documents. Quantitative simulation modeling explores different automation alternatives and their impact on laboratory workflow. Finally, integration of results in interactive semirealistic simulation tools for laboratory design or reengineering can be used as communications tools to involve laboratory professionals in the change of their practice.

PUSH Tool reality check: audience response. Pressure Ulcer Scale for Healing.

Following presentation of the Pressure Ulcer Scale for Healing (PUSH), conference participants broke into small discussion groups according to their practice settings: acute care, long-term care, and home care/outpatient care. Questions were posed to participants regarding the reality of using the PUSH Tool in their practice settings. These questions were structured to elicit comments about: (1) the characteristics of the PUSH Tool; (2) the validity, reliability, and practicality of the PUSH Tool; and (3) education and implementation requirements prior to use of the PUSH Tool. This article summarizes their comments, which will be used in refining the PUSH Tool.

Stone-tool usage by Thai long-tailed macaques (Macaca fascicularis).

In January and March of 2005, we conducted surveys of long-tailed macaques at Piak Nam Yai Island, Laem Son National Park (9 degrees N 34-35', 98 degrees E 28'), Ranong Province, situated in southern Thailand. Two of the three troops of long-tailed macaques found on the island were observed using axe-shaped stones to crack rock oysters, detached gastropods (Thais tissoti, Petit, 1852), bivalves (Gafrarium divaricatum, Gmelin, 1791), and swimming crabs (Thalamita danae, Stimpson, 1858). They smashed the shells with stones that were held in either the left or right hand, while using the opposite hand to gather the oyster meat. Some monkeys used both hands to handle the stones. According to Matsuzawa's 1996 hierarchical classification of tool usage (levels 0-3), the tool usage by Thai long-tailed macaques could be characterized as either level 1 (cracking rock oysters with stones) or level 2 (cracking drifting mollusks and crabs with stones by placing them on a rock). Our discovery of stone-tool usage by Thai long-tailed macaques provides a new point of reference for discussions regarding the evolution of tool usage and the material culture of primates.

Hiring for "organizational fit". A St. Louis system has developed tools for assessing candidates' compatibility with the organization.

To a great extent, the continued success of Catholic health care organizations is dependent on the selection of co-workers and leaders who are committed to carrying on the organization's mission. The Sisters of Mercy Health System, St. Louis, uses three tools to help leaders be more consistent and objective in assessing employment candidates for organizational fit. The first tool involves behavioral-based interviewing, which looks at a candidate's potential for future behaviors based on his or her past behaviors. The second tool assesses a candidate's values in such a way that accounts for and reduces the interviewer's own subjectivity. And the third tool-values-based interviewing-helps reveal a candidate's natural aptitude for, interest in, and personal agreement with the organization's charism, religious heritage, and values.

Capuchin monkey (Cebus apella) grips for the use of stone tools.

This research examined capuchin monkey (Cebus apella) grips for the use of throwing, nut-cracking and cutting tools. We provided subjects with stones and apparatus that accommodated the use of stones as tools. Our subjects exhibited five grips, two of which the animals used when force was the primary consideration (power grips) and three of which the animals used when accuracy of sensory judgment and instrumentation was required (precision grips). We believe that the range of contexts in which capuchins use stone tools, combined with the ability of capuchins to employ both power and precision grips as part of their tool repertoire, indicate that Cebus apella can be used to identify grips that facilitated hominid lithic technology.

Dietary responses to fruit scarcity of wild chimpanzees at Bossou, Guinea: possible implications for ecological importance of tool use.

A 13-month ecological study was conducted at Bossou, Guinea, West Africa, to elucidate how a community of wild chimpanzees (Pan troglodytes verus) deals with the scarcity of main foods. During the study period, fruit availability fluctuated radically. The chimpanzees were confirmed to depend heavily on three "keystone resources" which were available when their main foods (fruit pulp) were scarce. These were fruits of Musanga cecropioides, oil-palm (Elaeis guineensis) nuts, and oil-palm pith. These are abundant in the chimpanzees' home range and their nutritional contents compensate for a decrease in nutritional intake from fruit pulp. The presence of these excellent backup foods may explain the high reproductive performance of Bossou chimpanzees. Here, chimpanzees consumed two of the three keystone foods using two types of tool behavior: nut-cracking for oil-palm nuts and pestle-pounding for oil-palm pith. These tool-using behaviors accounted for 31.9% of the total feeding time spent in June (the month in which the highest frequency occurred) and 10.4% in total for the year. It is suggested that the Bossou chimpanzees depend strongly on tools for their subsistence. This implies a possible function for tool technology in the evolution of our human ancestors.

Spilling the beans on java 3D: a tool for the virtual anatomist.

The computing world has just provided the anatomist with another tool: Java 3D, within the Java 2 platform. On December 9, 1998, Sun Microsystems released Java 2. Java 3D classes are now included in the jar (Java Archive) archives of the extensions directory of Java 2. Java 3D is also a part of the Java Media Suite of APIs (Application Programming Interfaces). But what is Java? How does Java 3D work? How do you view Java 3D objects? A brief introduction to the concepts of Java and object-oriented programming is provided. Also, there is a short description of the tools of Java 3D and of the Java 3D viewer. Thus, the virtual anatomist has another set of computer tools to use for modeling various aspects of anatomy, such as embryological development. Also, the virtual anatomist will be able to assist the surgeon with virtual surgery using the tools found in Java 3D. Java 3D will be able to fulfill gaps, such as the lack of platform independence, interactivity, and manipulability of 3D images, currently existing in many anatomical computer-aided learning programs.

Development of an audit tool for genetic services.

Rapid growth in demand and altered professional roles have produced changes in the delivery of genetic services over the past decade, but these have not been rigorously evaluated because of the paucity of appropriate audit tools. The aim of this study was to use clients' accounts and factor analysis to develop a robust assessment and audit tool. Qualitative data abstracted from several published studies were used to generate a number of statements related to outcomes of genetic services. A total of 57 statements were incorporated into a questionnaire. The questionnaire was mailed to clients of the Wales genetic service (n = 133) who had completed their episode of care. Respondents were asked to rank each statement on a seven-point Likert type scale. Responses were subjected to factor analysis. A total of 97 anonymized responses were received (73% response rate). Six main factors were found to contribute to the outcome of the service from the client's perspective. These were labeled (i) enhanced understanding, (ii) positive psychological change, (iii) respect for autonomy, (iv) adaptation, (v) disequilibirium, and (vi) value of contact. The audit tool has now been refined for use in evaluating genetic services. Questions are included to investigate the six outcome areas shown to be relevant from the client's perspective. Data from the next phase of the study will be analyzed to validate the tool for use in both clinical audit and research contexts.

Tool use in insect foraging by the chimpanzees of Ngogo, Kibale National Park, Uganda.

Chimpanzee tool use for resource acquisition has been reported at numerous research sites. The chimpanzees of the Kibale Forest, western Uganda, have not previously been observed to use tools in foraging for insects. Here I report the first observation of tool use by the chimpanzees of the Ngogo community of Kibale National Park, Uganda, in insect foraging. Three adult females, one adolescent male, and one juvenile male were observed making and using tools to probe into a fallen dead tree to collect insect and wood pieces. I discuss the importance of this observation, and the behavioral similarities with chimpanzees from other sites.

Development of a disability measurement tool for juvenile rheumatoid arthritis. The Juvenile Arthritis Functional Assessment Scale.

A disability assessment tool, the Juvenile Arthritis Functional Assessment Scale, was developed for, and validated in, patients with juvenile rheumatoid arthritis (JRA). Standards for this 10-item tool were developed using the scores of 63 normal school children as controls and comparing these results with those of 71 age-matched JRA patients (age 7-16 years). The JRA patients scored statistically significantly higher on the scale, which also demonstrated excellent internal and convergent validity and internal reliability. The test is easily administered in 10 minutes by a physical or occupational therapist in a clinical or office setting. This tool represents the first normalized disability assessment tool developed for JRA patients.

BRIDGE (building the relationship between body image and disordered eating graph and explanation): a tool for parents and professionals.

BRIDGE (Building the Relationship Between Body Image and Disordered Eating Graph and Explanation) is a tool for mental health professionals, parents, teachers, and the general public. BRIDGE offers the potential for a new level of understanding between body image and disordered eating behaviors. This tool provides a framework that describes the connection between the attitudes we hold about our bodies and the corresponding behaviors we may practice. This practical tool takes fundamental concepts established in the eating disorder literature and presents them in a basic and easily understood manner. This paper invites further testing of this educational tool for parents, teachers, and professionals in a number of contexts including prevention and treatment programs.

A patient acuity and staffing tool for stroke rehabilitation inpatients based on the FIM instrument.

We undertook to develop a tool based on the FIM instrument to predict the number of nursing hours required to care for stroke patients in an acute inpatient rehabilitation program. The initial study to evaluate the feasibility of using the FIM instrument revealed that the total FIM score had a strong inverse relation to the level of care indicated by the Patient Care Index (PCI) at days 1, 5, 7, 10, 15, and 20 of rehabilitation (rs = -.76 to -.87). The results warranted continued investigation of the FIM instrument as a guide for nurse staffing decisions. Based on data from the initial study, five categories of FIM score ranges were designated that demonstrated the most accuracy of placing patients at the correct level of care. Special care considerations unique to institutional settings were identified and incorporated into the tool's final format, as were the calculations to determine the amount of assistance needed. The study reported here was undertaken to evaluate the level of care indicated by the adapted tool, compared with that of the PCI, in a sample of 67 stroke admissions. Spearman correlations revealed a moderate relationship (rs = .49 to .54) between the amount of care determined by the Patient Acuity and Staffing tool and through the PCI at the first, second, and third team meetings. We conclude that the system is an effective, efficient guide for scheduling nurse staffing on the stroke rehabilitation unit.

Use of bioinformatics tools for the annotation of disease-associated mutations in animal models.

Single-point mutations are one of the most frequent causes of genetic variability in both human and close species. The recent availability of different bioinformatics tools for annotating human single nucleotide polymorphisms (SNPs) has opened the possibility of using them to score SNPs from species with a biomedical interest, in particular from mice and other models of human disease. Also, this ability to predict pathogenicity of single point mutations in one species, based on data from another species, opens the possibility to predict the pathological character of single point mutations in humans using data from well-characterized model systems of human disease. This could provide a valuable alternative to the more traditional genetic population approaches. However, transferral of prediction tools may be limited by different factors, from a species bias in the training set, to a large sequence divergence between the proteomes of the training and the target species. Here we study the conditions under which prediction tools can be transferred among species, concentrating in the case of mice. We find that for the majority of the human-mouse homolog pairs, the sequence similarity is large enough to preserve the pathological character of mutations among species, in general. We then establish that prediction/annotation tools developed for one organism can be used to predict the neutral/pathological character of mutations/SNPs in the other organism.

Quantitative tools for comparing animal communication systems: information theory applied to bottlenose dolphin whistle repertoires.

Comparative analysis of nonhuman animal communication systems and their complexity, particularly in comparison to human language, has been generally hampered by both a lack of sufficiently extensive data sets and appropriate analytic tools. Information theory measures provide an important quantitative tool for examining and comparing communication systems across species. In this paper we use the original application of information theory, that of statistical examination of a communication system's structure and organization. As an example of the utility of information theory to the analysis of animal communication systems, we applied a series of information theory statistics to a statistically categorized set of bottlenose dolphin Tursiops truncatus, whistle vocalizations. First, we use the first-order entropic relation in a Zipf-type diagram (Zipf 1949 Human Behavior and the Principle of Least Effort) to illustrate the application of temporal statistics as comparative indicators of repertoire complexity, and as possible predictive indicators of acquisition/learning in animal vocal repertoires. Second, we illustrate the need for more extensive temporal data sets when examining the higher entropic orders, indicative of higher levels of internal informational structure, of such vocalizations, which could begin to allow the statistical reconstruction of repertoire organization. Third, we propose using 'communication capacity' as a measure of the degree of temporal structure and complexity of statistical correlation, represented by the values of entropic order, as an objective tool for interspecies comparison of communication complexity. In doing so, we introduce a new comparative measure, the slope of Shannon entropies, and illustrate how it potentially can be used to compare the organizational complexity of vocal repertoires across a diversity of species. Finally, we illustrate the nature and predictive application of these higher-order entropies using a preliminary sample of dolphin whistle vocalizations. The purpose of this preliminary report is to re-examine the original application of information theory to the field of animal communication, illustrate its potential utility as a comparative tool for examining the internal informational structure of animal vocal repertoires and their development, and discuss its relationship to behavioural ecology and evolutionary theory.

Experiments in coding clinical information: an analysis of clinicians using a computerized coding tool.

We present data from a controlled experiment with computerized browsing and encoding tool. Eighteen practicing clinicians were asked to extract medical concepts from narrative exercise cases using two approaches--traditional and computer-assisted use of ICD-9. Our results indicate that completeness of coding can be improved by up to 55% using a computerized coding tool; enforcing mandatory as opposed to optional modifier codes results in lower rates of incomplete coding (0 vs 55%), higher rates of correct coding (41 to 92%), and no change in the number of incorrect codings; and manual coding takes 100% longer than coding with the help of the computerized coding tool. Furthermore, clinicians need 59% more time for processing the whole set of codes than is suggested by the sum of individual codes. We conclude that use of a computerized coding tool can save time and result in higher quality coding However, de facto time spent on coding may be underestimated when looking at individual coding times instead of looking at the whole task of processing a clinical scenario.

A tool for analyzing and annotating genomic sequences.

We describe a tool for analyzing and annotating large genomic sequences containing introns. The analysis and annotation tool (AAT) includes two sets of programs, one for comparing the query sequence with a protein database and the other for comparing the query with a cDNA database. Each set contains a fast database search program and a rigorous alignment program. The database search program quickly identifies regions of the query sequence that are similar to a database sequence. Then the alignment program constructs an optimal alignment for each region and the database sequence. The alignment program also reports the coordinates of exons in the query sequence. Pairwise alignments of the query sequence with protein and cDNA database sequences are combined into multiple sequence alignments, which provide a view of all protein and cDNA sequences matching a query region. On a data set of 570 DNA sequences, AAT identified 94% of coding nucleotides correctly and 74% of exons exactly. Results of analyzing a human BAC sequence with the AAT tool are also presented. The AAT tool reduces the labor-intensive work of locating the exons of the query sequence and improves the process of defining intron-exon boundaries by using the wealth of available protein and cDNA data.

Tool-using strategies by early hominids at bed II, Olduvai Gorge, Tanzania.

This study examines the current prevailing model of Oldowan technology-the opportunistic, least-effort strategy of stone tool making and using by early hominids. The sample includes the MNK chert factory site and three contemporaneous assemblages from Olduvai Gorge, all dated between 1.65 and 1.53 m.y.a. The analysis suggests that early hominids at Olduvai may have been selective, applying distinctive strategies in making and using tools depending on the different types of raw materials available to them. The preponderance of lava cores and near absence of flakes associated with the cores suggest that lava cores at Olduvai did not provide a source of flakes. They were primarily heavy-duty core tools, despite the fact that the majority of Olduvai lava is of excellent quality for flaking. Contrary to this pattern, the abundance of chert flakes and the lack of large chert cores suggest that the production of flakes was the most important strategy applied to chert. Original forms and flaking mechanics of the raw materials may have been important factors in the simultaneous application of the different, complementary strategies. The Oldowan tool-using strategy was dynamic and flexible, in response to changes in raw material availability. The use of chert between 1.65 and 1.53 m.y.a. was apparently related to the drastic decrease in flake production in lava and quartz. Finally, lack of initial reduction episodes of lava material challenges the idea of the stone cache strategy at Olduvai between 1.65 to 1.53 m.y.a.
