Applications of computer software for the interpretation and management of mass spectrometry data in pharmaceutical science.

The rapid growth of mass spectrometry (MS)-based computer software applications has been fueled by the unprecedented need to capture and analyze MS data and provide the information necessary for decision-making. Shorter timelines and a significantly greater number of samples has resulted in a tremendous focus on streamlined approaches that provide scientists, managers, and executives the capability to readily obtain, or even request, the necessary information that leads to accelerated product development. The generation of analytical data using roboticized high-throughput hardware has produced a bottleneck since data can be generated faster than it can be analyzed. New techniques including MS/MS and accurate mass experiments are feasible only using computers to capture and manage the enormous amounts of data necessary to perform the experiments. Whatever the nature of the experiments conducted, the MS analysis strategy is to extract the appropriate information required for decision-making in as facile a manner as possible. We will review here a survey of the creation of commercial and laboratory specific reference databases and associated searching algorithms and also recent efforts to introduce advancedprocessing and analysis algorithms to the hands of the masses, specifically as an aid to structure elucidation.

Effectiveness of refusal skills software.

This research explores the potential of making social skills training more accessible to schools by the use of computer-aided instruction. An easy-to-use software program called Refusal Challenges, which targets important social skills with effective training methods, was tested. The dependent measure was demonstration of refusal skills strategies. One-hundred-eighty-eight male and female eighth-grade students were stratified according to pre-treatment refusal skill level, gender, and teacher. They were then randomly assigned from the stratified blocks to either the computer-based refusal skills training group or a control group. Repeated measures analyses of variance indicated a significant and meaningful time by treatment interaction for refusal skills scores. The difference between treatment and control groups remained significant and meaningful at both the post-test and follow-up testing.

Impact of software and hardware technologies on occupational health and safety policies in Saudi Arabian oil refineries.

This article seeks to examine the impact of technology importation on occupational health and safety in both Saudi Arabian and U.S. oil refining industries. Technologies imported to the Saudi oil industry take two forms: hardware (sophisticated equipment to run oil facilities) and software (policies and regulations pertaining to workers' health and safety, and employment rights installed by Aramco's founding multinational companies). This study utilizes qualitative, historically oriented, cross-national case studies to compare and assess workers' health, safety, and rights in Saudi Aramco with its U.S. counterpart, Motiva Enterprises. Two facilities were chosen to conduct field research: the Saudi Aramco oil refinery at Jeddah and Motiva's refinery at Port Arthur, Texas. The Jeddah refinery is fully owned by Saudi Aramco, thus, representing Aramco's health and safety policies and regulations. The Port Arthur refinery serves as a reference case study for U.S. oil refining facilities. The aspects of occupational health and safety in Saudi Aramco--ExxonMobil's joint ventures SAMREF and LUBREF--also are discussed to examine workers' health policies in both companies. The American oil industry made a significant contribution in establishing the Saudi oil industry, with the cooperation of the Saudi government. Despite having outstanding employment benefits schemes in Saudi Aramco, the presence of an organized work force better serves employee participation in Motiva than in Aramco. Safety systems such as Process Safety Management (PSM)--applied in Motiva--partially exist in Aramco to operate hardware technologies safely. Motiva training systems are better through PACE's Triangle of Prevention (TOP). Both companies follow the same pattern of handling occupational injuries and diseases; however, Saudi government agencies (GOSI) are responsible for compensating and treating injured workers. Saudi workers expressed conditional support for the worker committee program proposed by the Ministry of Labor. American and Saudi workers are concerned about the quality and sufficiency of health and safety training, employment promotion, work pressure, and job uncertainty due to continuous downsizing. This article recommends that Saudi social actors increase safety and health awareness in the work environment by providing intensive occupational safety training to the employees (as demanded by Saudi and American workers), improve labor-management relations through establishing strong cooperative contacts with regional and international trade unions, and establish uniform and standard occupational health and safety regulations for Saudi Aramco and its subsidiaries in order to provide an equal level of protection for Saudi workers.

A Java-based electronic healthcare record software for beta-thalassaemia.

BACKGROUND: Beta-thalassaemia is a hereditary disease, the prevalence of which is high in persons of Mediterranean, African, and Southeast Asian ancestry. In Greece it constitutes an important public health problem. Beta-thalassaemia necessitates continuous and complicated health care procedures such as daily chelation; biweekly transfusions; and periodic cardiology, endocrinology, and hepatology evaluations. Typically, different care items are offered in different, often-distant, health care units, which leads to increased patient mobility. This is especially true in rural areas. Medical records of patients suffering from beta-thalassaemia are inevitably complex and grow in size very fast. They are currently paper-based, scattered over all units involved in the care process. This hinders communication of information between health care professionals and makes processing of the medical records difficult, thus impeding medical research. OBJECTIVES: Our objective is to provide an electronic means for recording, communicating, and processing all data produced in the context of the care process of patients suffering from beta-thalassaemia. METHODS: We have developed - and we present in this paper - Java-based Electronic Healthcare Record (EHCR) software, called JAnaemia. JAnaemia is a general-purpose EHCR application, which can be customized for use in all medical specialties. Customization for beta-thalassaemia has been performed in collaboration with 4 Greek hospitals. To be capable of coping with patient record diversity, JAnaemia has been based on the EHCR architecture proposed in the ENV 13606:1999 standard, published by the CEN/TC251 committee. Compliance with the CEN architecture also ensures that several additional requirements are fulfilled in relation to clinical comprehensiveness; to record sharing and communication; and to ethical, medico-legal, and computational issues. Special care has been taken to provide a user-friendly, form-based interface for data entry and processing. RESULTS: The experience gained through the use of JAnaemia in 4 Greek hospitals reveals a significant contribution towards (1) improvement of the quality of the data being recorded, since data entry is guided by appropriate forms, (2) easier cooperation between physicians, who share a common information repository, and (3) increased processing capabilities, which facilitate medical research. CONCLUSIONS: JAnaemia appears to be a useful tool, which can improve the quality of care offered to beta-thalassaemic patients in Greece.

The actigraph data analysis software: I. A novel approach to scoring and interpreting sleep-wake activity.

Decades of empirical observations have established the validity of actigraphy primarily in individuals without sleep disorders. Methodological problems encountered thus far coupled with the widespread use of actigraphy signal the need for concentrated efforts to establish a consensus regarding scoring procedures. Currently available scoring methods show less reliability in clinical populations. To address these issues two validation studies were conducted: one for individuals without sleep disorders and the other for patients diagnosed with insomnia. The results of these two studies using the Actigraph Data Analysis Software as the scoring method have shown that the described system is fairly precise. It can be used for actigraphs with different features and mode of operation and is applicable to individuals with insomnia. These findings corroborate previous research showing that actigraphy is a valid instrument for assessment of sleep and wakefulness.

Imagix: multimedia software for evaluating the vividness of movement-imagery.

This article presents a new software, Imagix, designed for the evaluation of the vividness of movement-imagery. This multimedia test is comprised of 18 movements in six different psychomotor categories whose vividness of imagery is to be appraised. Imagix has the advantage of offering an evaluation of the vividness of imagery in a normative way. The participant chooses among four films displaying a vividness gradient, which includes contrast and luminosity. The participant is first asked to visualize a movement verbally suggested. The participant is then asked to evaluate the vividness of this mental image by choosing on a computer screen the movie that best corresponds to the vividness of the movement-imagery. The first versions of this freeware (in English and French) are currently being validated.

A software tool to assist placement of multiple parallel brachytherapy sources using the Brown-Roberts-Wells stereotactic system.

The authors present a simple software written in Turbo Pascal which allows placement of multiple parallel sources for interstitial brachytherapy using the Brown-Roberts-Wells CT stereotactic system. The user can choose any direction in space, independently from the CT plane, and any number of linear sources arranged on one or more hypothetical cylinders of variable radius. The sources can be rotated on the cylinder in order to avoid critical structures. This small program runs on any IBM compatible computer.

Genetic analysis of clinical mastitis data from on-farm management software using threshold models.

Producer-recorded clinical mastitis data from 77,791 cows in 418 herds were used to determine the potential for genetic improvement of mastitis resistance using data from on-farm management software programs. The following threshold sire models were applied: 1) a single-trait lactation model, where mastitis was recorded as 0 or 1 in first lactation only; 2) a 3-trait lactation model, where mastitis was recorded as 0 or 1 in each of the first 3 lactations, and 3) a 12-trait, lactation-segment model, where mastitis was recorded as 0 or 1 in each of 4 segments (0 to 50, 51 to 155, 156 to 260, and 261 to 365 d postpartum) in each of the first 3 lactations. Lactation incidence rates were 0.16, 0.20, and 0.24 in first, second, and third lactation, respectively, and incidence rates within various segments of these lactations ranged from 0.036 in late first lactation to 0.093 in early third lactation. Estimated heritability of liability to clinical mastitis ranged from 0.07 to 0.15, depending on the model and stage of lactation. Heritability estimates were higher in first lactation than in subsequent lactations, but estimates were generally similar for different segments of the same lactation. Genetic correlations between lactations from the 3-trait model ranged from 0.42 to 0.49, while correlations between segments within lactation from the 12-trait model ranged from 0.26 to 0.64. Based on the results presented herein, it appears that at least 2 segments are needed per lactation, because mastitis in early lactation is lowly correlated with mastitis in mid or late lactation. Predicted transmitting abilities of sires ranged from 0.77 to 0.89 for probability of no mastitis during the first lactation and from 0.36 to 0.59 for probability of no mastitis during the first 3 lactations. Overall, this study shows that farmer-recorded clinical mastitis data can make a valuable contribution to genetic selection programs, but additional systems for gathering and storing this information must be developed, and more extensive data recording in progeny test herds should be encouraged.

Coding observational data: a software solution.

The analysis of observational data, particularly from social interactions, is often made difficult by the process of transcribing the verbal and behavioral interactions, having observers code on the transcriptions, and then transferring those codes to a statistical analysis program. The advent of computer-aided coding schemes has, to some extent, eliminated this laborious and time-consuming process. However, existing programs may not fulfill the needs of all of the researchers interested in this methodology, and furthermore, the expense of current systems may put these tools out of reach for some. The Observational Data Coding System (ODCS) software package presented here is a flexible coding tool designed to make efficient the process of coding observational data. A control panel allows the researcher to customize the program and coding system to suit his or her research questions. A variety of media (including video, audio, image, and text) can be read directly into the Windows-based program; trained observers can then code a variety of factors via buttons on the screen while the file is playing. An example of using the program to analyze conversation is provided. ODCS is a flexible, free tool for the coding of observational data.

The Glance software package.

We describe the Glance software package, which takes advantage of tablet PC technology to control experiments that require participants to reconstruct complex stimuli, as with the Chase and Simon (1973) chess reconstruction task, and to present tests that require participants to refer briefly to critical displays, as with the digit-symbol task. Participants press the space bar, which allows access to the stimulus and, simultaneously, prohibits drawing on the tablet. At release of the space bar--or optionally, after some period of time--the stimulus is hidden, and the drawing tools are enabled. Output from Glance allows analysis as fine grained as each stroke or as coarse as the entire image.

Software for recording observational files.

We offer the new software Codex, written in Visual Basic 3.0. It is a tool adequate in observational methodology. Its fundamental objective is to record motor and verbal behavior using the data types proposed by Bakeman and Quera (1995, 1996), together with the field formats proposed by Hall (1963), Weick (1968), Hutt and Hutt (1974), and Anguera (1979). It is designed to allow for data interchange between specific programs in use in observational methodology (SDIS-GSEQ, The Observer, and Theme) and other general programs (spread sheets, statistics applications, word processing programs, sound cards, etc.).

MFDTool: a software program for designing optimal multifunction displays.

This paper describes a software program called MFDTool. MFDTool is used to design multifunction displays (MFDs), which enable people to interact with computer information systems. MFDTool characterizes the problem of MFD design as the identification of how people interact with the system and what types of constraints should be imposed by the designer to shape the properties of the MFD. Once this information is provided, MFDTool uses an optimization procedure to build a variety of candidate MFD designs and to identify the MFD design that best satisfies the constraints. An example of MFD design is discussed.

The generation effect: software demonstrating the phenomenon.

The generation effect occurs when people demonstrate better memory for material that they have generated than for material that they have merely read. The software described here allows students to participate in replications of generation effect experiments. The program can be used with its default settings to present simple experiments. I have used this feature in research methods courses to provide data for writing research reports. The program can also be modified to allow students to design and conduct their own variations of generation effect experiments.

Hardware and software for tachistoscopy: how to make accurate measurements on any PC utilizing the Microsoft Windows operating system.

Methods for automated stimulus display and accurate response time measurement with IBM-compatible PCs are of great importance in cognitive research designs. Accurate measurements of reaction times are required to interpolate other measures, such as speed of mental processing. We present a description of hardware and software that displays stimulus images and performs reaction timing that is not dependent on PC performance characteristics. This is accomplished by electronically bypassing timing errors normally inherent to the operation of the computer. A high-precision external timer measures the time between stimulus onset and a subject's push-button response while a video blanking circuit controls the video presented to the monitor screen. Two options for accurately detecting stimulus onset are presented: (1) A photodetector can be used to sense the actual onset of the stimulus on a secondary video monitor screen; (2) the video blanking circuit can provide a signal coincident with the initiation of video to the monitor. Both methods result in a system timing accuracy of 100 microseconds.
