The effects of container size, frequency and extended horizontal reach on maximum acceptable weights of lifting for female industrial workers.

In the development of our present manual materials handling (MMH) guidelines (Snook, S.H., Ciriello, V.M., 1991. The design of manual tasks: revised tables of maximum acceptable weights and forces. Ergonomics 34, 1197-1213), the assumption was made that the effects of frequency on maximum acceptable weights (MAWs) of lifting with a large box (hand distance, 38 cm from chest) were similar to that of lifting with a small box (hand distance, 17 cm from chest). The first purpose of the present experiment was to investigate this assumption with female industrial workers. The second purpose was to study the effects of extended horizontal reach lifting (hand distance, 44.6 cm from chest) on MAWs as a confirmation of the results of a previous studies on this variable with males (Ciriello, V.M., Snook, S.H., Hughes, G.J., 1993. Further studies of psychophysically determined maximum acceptable weights and forces. Hum. Factors 35(1), 175-186; Ciriello, V.M., 2003. The effects of box size, frequency, and extended horizontal reach on maximum acceptable weights of lifting. Int. J. Ind. Ergon. 32, 115-120). Lastly, we studied the effects of high frequency (20 lifts/min) on MAWs of lifting. Ten female industrial workers performed 15 variations of lifting using our psychophysical methodology whereby the subjects were asked to select a workload they could sustain for 8h without "straining themselves or without becoming unusually tired weakened, overheated or out of breath". The results confirmed that MAWs of lifting with the large box was significantly effected by frequency. The frequency factor pattern in this study was similar to the frequency pattern from a previous study using the small box (Ciriello, V.M., Snook, S.H., 1983. A study of size distance height, and frequency effects on manual handling tasks. Hum. Factors 25(5), 473-483) for all fast frequencies down to one lift every 2 min with deviations of 7%, 15%, and 13% for the one lift every 5 and 30 min tasks and the one lift in 8h task, respectively. The effects of lifting with an extended horizontal reach decreased MAW 22% and 18% for the mid and center lift and the effects of the 20 lifts/min frequency resulted in a MAW that was 47% of a 1 lift/min MAW. Incorporating these results in future guidelines should improve the design of MMH tasks for female workers.

Food acceptability in field studies with US army men and women: relationship with food intake and food choice after repeated exposures.

Laboratory data with single exposures showed that palatability has a positive relationship with food intake. The question addressed in this study is whether this relationship also holds over repeated exposures in non-laboratory contexts in more natural environments. The data were collected in four field studies, lasting 4-11 days with 307 US Army men and 119 Army women, and comprised 5791 main meals and 8831 snacks in total. Acceptability was rated on the nine point hedonic scale, and intake was registered in units of 1/4, 1/2, 3/4, or 1 or more times of the provided portion size. Correlation coefficients between individual acceptability ratings and intakes varied from 0.22 to 0.62 for the main meals (n=193-2267), and between 0.13 and 0.56 for the snacks (n=304-2967). The likelihood of choosing a meal for the second time was positively related to the acceptability rating of the meal when it was consumed for the first time. The results reinforce the importance of liking in food choice and food intake/choice behavior. However, the magnitude of the correlation coefficients between acceptability ratings and food intake suggest that environmental factors also have an important role in determining intake and choice.

Specific social influences on the acceptance of novel foods in 2-5-year-old children.

Social influences have been shown to be very important to overcome food neophobia in young children. However, there is no experimental evidence about whether social influences on food acceptance are specific, that is if models eating the same food as the child are more effective in promoting food acceptance than models eating a different food. We assessed children's behavior towards novel foods when an adult model (a) was not eating (Presence condition), (b) was eating a food of a Different color (Different color condition), and (c) was eating a food of the Same color (Same color condition). We tested 27 children (ages 2- to 5-years-old) recruited from The Pennsylvania State University day-care facilities. Results show that children accepted and ate their novel food more in the Same color condition than in the Different color and in the Presence conditions. Therefore, in young children food acceptance is promoted by specific social influences. These data indicate that children are more likely to eat new food if others are eating the same type of food than when others are merely present or eating another kind of food.

Awareness, acceptance of and willingness to buy genetically modified foods in Urban China.

There is concern about the extent to which consumers will accept genetically modified (GM) foods if they are commercialized in China. The evidence from the existing literature is mixed and sometimes confusing. The objective of this study is to conduct a large in-depth face-to-face in-house survey that examines the consumers' awareness, acceptance of and willingness to buy GM foods in China. To achieve this objective, a well-designed consumer survey was conducted in 11 cities of five provinces in Eastern China in 2002 and 2003. The results indicate that despite much less information on GM foods available publicly in China, more than two thirds of consumers in urban areas have heard of GM foods. But their knowledge on biotechnology was limited. Chinese consumers' acceptance of and willingness to buy GM foods was much higher than in other countries. Chinese consumers also demonstrated great variance in their acceptance of different GM foods. Information and prices of GM foods were two important factors affecting consumers' attitudes toward GM foods. Based on the findings of this study and given that our sample is in the more developed eastern Urban China, we conclude that the commercialization of GM foods is not likely to receive great resistance from the consumers in China.

Development, feasibility, acceptability, and preliminary impact of NutriSOS®: A behavioral mobile app to promote sustainable diets.

The primary objective of this study was to describe the development of the NutriSOS® app and to evaluate its feasibility and acceptability for its use in the NutriSOS® Randomized Controlled Trial (RCT) to promote sustainable diets. A secondary objective was to explore preliminary changes in dietary and physical activity behaviors and environmental impact following app use. The NutriSOS® app integrates personalized dietary advice, educational content, self-monitoring, and social interaction features. A single-arm, pre-post pilot study was conducted in 37 young Mexican adults over four weeks. Feasibility, acceptability, quality, and usability were assessed using online surveys, alongside exploratory changes in dietary and physical activity behaviors, environmental indicators, and their association with perceived behavioral determinants. Feasibility and acceptability were high overall, with favorable responses reaching up to 100% in key components such as the nutritional guide and learning modules, and above 90% for messaging, registration, and design. Greater variability was observed in some sections, particularly the 24-h recall (41-86%). Reductions in red and processed meat and ultra-processed food consumption were observed (from 3 to 1 times/week, p < 0.01), with ∼60% decreases in their related environmental footprints (p < 0.01) and favorable self-reported behavioral determinants (p < 0.0001). Physical activity type and intensity changed (p < 0.05). These findings support NutriSOS® as a feasible and acceptable tool, while highlighting areas for refinement, particularly those related to the time and effort required for data entry, prior to its implementation in the NutriSOS® RCT, in which its effectiveness will be formally evaluated.

Effects of suppression and acceptance on emotional responses of individuals with anxiety and mood disorders.

The present investigation compared the subjective and physiological effects of emotional suppression and acceptance in a sample of individuals with anxiety and mood disorders. Sixty participants diagnosed with anxiety and mood disorders were randomly assigned to one of two groups. One group listened to a rationale for suppressing emotions, and the other group listened to a rationale for accepting emotions. Participants then watched an emotion-provoking film and applied the instructions. Subjective distress, heart rate, skin conductance level, and respiratory sinus arrhythmia were measured before, during, and after the film. Although both groups reported similar levels of subjective distress during the film, the acceptance group displayed less negative affect during the post-film recovery period. Furthermore, the suppression group showed increased heart rate and the acceptance group decreased heart rate in response to the film. There were no differences between the two groups in skin conductance or respiratory sinus arrhythmia. These findings are discussed in the context of the existing body of research on emotion regulation and current treatment approaches for anxiety and mood disorders.

Acceptability of five nonoxynol-9 spermicides.

OBJECTIVE: To examine the acceptability of five nonoxynol-9 (N-9) spermicides. METHODS: We analyzed data from a randomized trial of five products, including three gels containing different amounts of N-9 per dose, a film and a suppository. In the trial, 1536 participants were asked to use the assigned spermicide for 7 months and to complete questionnaires 4 weeks after admission and at discontinuation. RESULTS: Overall, 43% of participants liked their spermicide "very much." This proportion was higher in the three gel groups than in the suppository and film groups. Difficulty with insertion, messiness and discontent with timing of insertion were common complaints in all groups. After adjustment for selected baseline factors, acceptability on the first questionnaire was not related to duration or consistency of subsequent spermicide use or to subsequent time to pregnancy. CONCLUSIONS: In this study, all five spermicides were considered acceptable by most users. Acceptability did not appear to influence spermicide use or pregnancy risk.

Acceptability of a home monitor used to aid in conception: psychosocial factors and couple dynamics.

BACKGROUND: Assessing the psychological acceptability of technologies designed to assist couples in achieving pregnancy is complex. OBJECTIVE: The current study developed measures relating to the impact of one such technology on 52 couples' relationships, their feelings relating to pregnancy status and their feelings about the technology itself. METHODS: Pregnancy status and daily logs of sexual activity were recorded for four menstrual cycles, in addition to the completion of acceptability questionnaires. RESULTS: Baseline acceptability measures were more favorable among couples eventually achieving pregnancy. For couples not becoming pregnant, acceptability declined over time and relationships became more strained. Behavioral data clearly indicated a "targeting" and focusing of sexual activity in response to the information displayed by the monitor. CONCLUSION: Expectations of success, couple disagreements about prior failure and partner communication patterns appear to be related to pregnancy success when using such technology.

Operative laparoscopy in The Netherlands: Diffusion and acceptance.

OBJECTIVE: To evaluate and update the current status of the implementation of operative laparoscopy in gynaecology in The Netherlands by assessing diffusion and acceptance of each specific procedure per hospital. STUDY DESIGN: In 2003 a questionnaire was sent to all hospitals (n = 102), which addressed the total number and type of laparoscopic procedures performed in 2002 stratified by level of difficulty (level 1: diagnostic laparoscopy, sterilization, tubal patency tests; level 2: adhesiolysis, ectopic pregnancy (EP), laparoscopic treatment of endometriosis, cystectomy, oophorectomy, LAVH, tubal surgery for infertility; level 3: myomectomy, total laparoscopic hysterectomy (TLH) and sacropexy). Data were compared to previously published data of 1994. RESULTS: Response rate was 79% (81/102). Diffusion and acceptance of level 2 procedures increased significantly, except endometriosis and tubal surgery for infertility. Diffusion of LAVH was only 58%. Four percent of hysterectomies were LAVH. TLH and sacropexy were not performed. The diffusion of myomectomy increased significantly (p = 0.01), whereas its acceptance remained low. CONCLUSIONS: Although the diffusion of operative procedures has increased over the last decade, acceptance is still limited, especially for laparoscopic hysterectomy. The implementation of operative gynaecological laparoscopy in The Netherlands seems to develop at a slow pace.

Comparing acceptance- and control-based coping instructions on the cold-pressor pain experiences of healthy men and women.

The current study reflects recent developments in psychotherapy by examining the effect of acceptance-based coping instructions, when compared to the opposite, more control/distraction-based instructions, on cold-pressor pain. Since previous research indicates gender differences in how people cope with pain, we also sought to determine whether differences would be found between healthy men and women. As predicted, results indicated that women reported lower pain threshold and tolerance level than did men. Furthermore, the acceptance-based instruction resulted in lower sensory pain reports when compared to the opposite instructions. Finally, for affective pain, acceptance instructions only benefited women. These results suggest that acceptance-based coping may be particular useful in moderating the way in which individuals, especially women, cope with pain.

Exposure and acceptance in the rehabilitation of adolescents with idiopathic chronic pain - a pilot study.

For chronic pain of unclear origin (idiopathic), pharmacological therapy is often insufficient. Psychological treatment strategies have been developed and evaluated for adults with chronic pain. However, few such studies are seen with youths, and to date there is limited empirical evidence regarding the effectiveness of psychological treatment for generalized musculoskeletal pain syndromes in adolescents. Acceptance and commitment therapy (ACT) is a development of cognitive behaviour therapy emphasizing exposure and acceptance. In this pilot study, 14 adolescents referred to the pain treatment service due to chronic debilitating pain were treated using an ACT-based approach. It was hypothesized that avoidance of pain and related stimuli was central to the disability seen among these patients, and that exposure and acceptance strategies could increase functioning and decrease pain. In contrast to emphasizing reductions in pain and distress, the treatment objective was to improve functioning by increasing the patient's ability to act in line with personal values in the presence of negative thoughts, emotions or bodily sensations. Following treatment, and retained at 3- and 6-month follow-up, improvements in functional ability, school attendance, catastrophizing and pain (i.e., intensity and interference) were seen. The outcome of this pilot study indicates that exposure and acceptance can been useful in the rehabilitation of adolescents with chronic debilitating pain. Randomized controlled studies are needed to empirically evaluate the effectiveness of this approach.

HIV surveillance in theory and practice: assessing the acceptability of California's non-name HIV surveillance regulations.

In 2002, California adopted a non-name system for HIV case reporting. This study focused on the acceptability of a non-name reporting system among key stakeholders implementing the system. We conducted qualitative research during the pre- and post-implementation period of the non-name HIV reporting regulations. During both study periods we conducted key informant in-depth interviews (n = 48 and 52, respectively) with health department surveillance staff, laboratory personnel, health care providers and clinic staff; and we conducted four focus group discussions (n = 28 and 30, respectively) with representatives of community-planning group members and advocacy groups. We found that overall, California's non-name HIV reporting regulations were acceptable to most key stakeholders. Acceptability of a non-name system was highest among advocates and healthcare providers. Views of health department staff varied across the four counties, with some expressing a strong preference of a names based system and others accepting the non-name system.

Differing faculty and housestaff acceptance of an electronic health record.

In order to determine whether differences exist between housestaff and faculty physician acceptance of an electronic health record system, we conducted a written survey of attitudes towards new electronic medical record at the University of Illinois at Chicago. We surveyed 330 faculty and housestaff physicians. User acceptance of the EHR was high for both faculty physicians and housestaff. An amount of 88.0% of the housestaff and 64.7% of the faculty preferred the EHR over a paper record. Although both housestaff and faculty acceptance of an EHR was high, housestaff showed greater approval ratings than faculty. Central to acceptance of an EHR is conservation of physician time, including improving system speed, reducing time spent waiting for a computer to become available, and minimizing time spent documenting care.

Mobile computing acceptance factors in the healthcare industry: a structural equation model.

OBJECTIVE: This paper presents a revised technology acceptance model to examine what determines mobile healthcare systems (MHS) acceptance by healthcare professionals. METHOD: Conformation factor analysis was performed to test the reliability and validity of the measurement model. The structural equation modeling technique was used to evaluate the causal model. RESULTS: The results indicated that compatibility, perceived usefulness and perceived ease of use significantly affected healthcare professional behavioral intent. MHS self-efficacy had strong indirect impact on healthcare professional behavioral intent through the mediators of perceived usefulness and perceived ease of use. Yet, the hypotheses for technical support and training effects on the perceived usefulness and perceived ease of use were not supported. CONCLUSION: This paper provides initial insights into factors that are likely to be significant antecedents of planning and implementing mobile healthcare to enhance professionals' MHS acceptance. The proposed model variables explained 70% of the variance in behavioral intention to use MHS; further study is needed to explore extra significant antecedents of new IT/IS acceptance for mobile healthcare. Such as privacy and security issue, system and information quality, limitations of mobile devices; the above may be other interesting factors for implementing mobile healthcare and could be conducted by qualitative research.

The influence of the oscillation angle and the neck anteversion of the prosthesis on the cup safe-zone that fulfills the criteria for range of motion in total hip replacements. The required oscillation angle for an acceptable cup safe-zone.

A normal hip joint has more than 120 degrees flexion. The reduced range of motion (ROM) of total hip arthroplast leads to frequent prosthetic impingement, subluxation and dislocation. Prosthetic impingement may be more serious for metal-on-metal and ceramic-on-ceramic total hip prosthesis (THP). A larger oscillation angle of THP (OsA) and proper cup and neck positions make a larger theoretical ROM of a patient's artificial hip joint. But what OsA is required and what range of cup positions is kinetically accepted are not clearly understood. A ROM of more than 120 degrees flexion, 45 degrees internal-rotation at 90 degrees flexion, 30 degrees extension and 40 degrees external-rotation was defined as severe criteria for an acceptable ROM. Theoretical cup safe-zones were created that fulfill the severe criteria of ROM for (OsA=110 degrees , 120 degrees , 135 degrees ) by the mathematical formulas. The size of the cup safe-zone mainly depends on the size of the OsA. There is no cup safe-zone for 110 degrees OsA, an extremely small safe-zone for 120 degrees OsA and an acceptable safe-zone for 135 degrees OsA. Each THP has its own OsA, because OsA is the function of head and neck diameter and cup design. More than 135 degrees OsA enlarges the safe-zone of the prosthetic position, so it extends the acceptable range of error that surgeons cannot avoid completely. However, few THPs with more than 135 degrees OsA are currently clinically available. Both surgeons and manufacturers must realize that OsA is as essential as cup and neck orientations for ROM.

Acceptability of lower glycemic index foods in the diabetes camp setting.

OBJECTIVE: To determine the acceptability of lower glycemic index (GI) foods served at diabetes camp. DESIGN: Crossover design of standard and lower GI menus. SETTING: Three consecutive 5-day diabetes camp sessions. PARTICIPANTS: 140 youth, age 7-16, with type 1 or 2 diabetes. INTERVENTION: A standard camp cycle menu was reformulated to include 2 1/2 days of standard foods and 2 1/2 days of lower GI foods. MAIN OUTCOME MEASURES: Youth provided satisfaction ratings after meals and snacks using measures designed for this study. Observations of food consumption were conducted on a random sample of youth for each meal. ANALYSIS: Descriptive analyses and t-tests were conducted to assess differences in satisfaction with and consumption of standard and lower GI foods. RESULTS: Lower GI foods served at dinner and for snacks received satisfaction ratings equal to standard foods (dinner: 3.68 lower GI versus 3.79 standard, P = .30; snacks: 3.74 lower GI versus 3.79 standard, P = .60). Lower GI foods served at breakfast and lunch received lower, though very acceptable, ratings (breakfast: 3.76 lower GI versus 4.04 standard, P < .01; lunch: 3.64 lower GI versus 3.88 standard, P = .01). Consumption of all meals was acceptable. No differences occurred in the frequency of high or low blood sugars between standard and lower GI days. CONCLUSIONS AND IMPLICATIONS: Higher quality carbohydrates may be provided to youth in institutional settings while maintaining sufficient levels of acceptability; specific findings are instructive for designing efforts to increase their consumption.

Validation in pharmaceutical analysis. Part II: Central importance of precision to establish acceptance criteria and for verifying and improving the quality of analytical data.

Validation of analytical procedures is a vital aspect not just for regulatory purposes, but also for their efficient and reliable long-term application. In order to address the performance of the analytical procedure adequately, the analyst is responsible to identify the relevant parameters, to design the experimental validation studies accordingly and to define appropriate acceptance criteria. Establishing an acceptable analytical variability for the given application is of central importance as many other acceptance criteria can be derived from such a precision. Acceptable precision ranges for types of control tests and/or analytes can be obtained from validation, but also related activities such as transfer, control charts, or extracted from routine applications such as batch release or stability studies (data mining). Apart from compiling a database for general benchmarking, during such an information-building process, the reliability of the analytical variability of the specific procedure is more and more increased. This is important as a reliable target variability facilitates to detect or investigate atypical or out-of specification behaviour of analytical data in a routine application, thus improving the data quality and reliability. According to the life-cycle concept of validation, measures should be taken to maintain and control the validated status of analytical procedures during long-term routine application, such as monitoring relevant performance parameters (system suitability tests), control charts, etc. If the analytical system is demonstrated to be stable, i.e. under statistical control, a major variability contribution in LC originating from the standard preparation and analysis can be reduced. A concept of quantification by pre-determined calibration parameters instead of the classical approach of simultaneous calibration is described.

Genes encoding for AP-2beta and the Serotonin Transporter are associated with the Personality Character Spiritual Acceptance.

In several twin studies the relative contribution of genetic factors for personality traits has amounted to figures between 40 and 60%. In the present study we investigated to which degree polymorphisms in the 5-HTT and AP-2beta genes are implicated in the neural processes involved in the formation of Temperament and Character traits, as estimated by Cloninger's TCI. Considering the background of previous reports, associations with the character Self-Transcendence and its sub-scale Spiritual Acceptance in particular, were of interest. A stratified random sample of 200 individuals (total population=5173), matched for age, gender and risk behaviors, from volunteering 16- and 19-year-old adolescents students in Sweden was investigated. Cloninger's TCI inventory was used for investigation of temperament and character traits. Blood samples were used for analyses of a promoter serotonin transporter polymorphism (5-HTTLPR) and an intron 2 polymorphism in the transcription factor AP-2beta gene. Among boys individuals with presence of the short 5-HTTLPR genotype showed lower scores, whereas individuals with presence of the short AP-2beta genotype showed higher scores of personality character Self-Transcendence and its sub-scale Spiritual Acceptance. Among girls no effect of either genotype was found. Both among boys and girls, significant interactive effects were found between 5-HTTLPR and AP-2beta genotypes, with regard to Self-Transcendence and Spiritual acceptance. Boys and girls with the combination of presence of the short 5-HTTLPR, and homozygosity for the long AP-2beta genotype scored significantly lower on Self-Transcendence and Spiritual Acceptance.
