Bounded rationality and satisficing in young people's Web-based decision making

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 1 2002
Denise E. Agosto
This study investigated Simon's behavioral decision-making theories of bounded rationality and satisficing in relation to young people's decision making in the World Wide Web, and considered the role of personal preferences in Web-based decisions. It employed a qualitative research methodology involving group interviews with 22 adolescent females. Data analysis took the form of iterative pattern coding using QSR NUD*IST Vivo qualitative data analysis software. Data analysis revealed that the study participants did operate within the limits of bounded rationality. These limits took the form of time constraints, information overload, and physical constraints. Data analysis also uncovered two major satisficing behaviors,reduction and termination. Personal preference was found to play a major role in Web site evaluation in the areas of graphic/multimedia and subject content preferences. This study has related implications for Web site designers and for adult intermediaries who work with young people and the Web. [source]

Antibiotic prophylaxis in elective colorectal surgery

ANZ JOURNAL OF SURGERY, Issue 4 2002
Yunus A. Gul
Background: Antibiotics are often administered in elective colorectal surgery to prevent wound infection. The tendency for surgeons to prolong the administration of prophylactic antibiotic therapy in the postoperative period is a well-known fact. The aim of this study was to elucidate the pattern of prophylactic antibiotic utilization in elective colorectal surgery and to determine if evidence-based medicine is employed in relation to this practice. Methods: A cross-sectional study encompassing general surgeons performing elective colorectal surgery was performed. Questionnaires were distributed to 144 surgeons (national, academic and private health care). Questions pertaining to the type, timing and duration of antibiotic administration were asked. The prevalence of wound infection audit rate and whether or not there were specific guidelines related to antibiotic administration were also determined. Results: The response rate obtained was 67% (n = 96). Although evidence from the current medical literature and recommended national guidelines support the use of single-dose prophylactic antibiotics, 72% of the respondents used more than a single dose. Forty surgeons (42%) claimed that their prescribing practice was supported by the medical literature, 31 respondents (32%) based their practice on hospital guidelines and personal preference was cited as a reason by 21 surgeons (22%). The remaining four respondents (4%) used a similar scheduling policy to that practiced by their colleagues in relation to antibiotic administration. There was no significant difference in antibiotic dose scheduling between national, private and university academic institutions (P = 0.85). Conclusions: These results suggest that a significant proportion of surgeons administer excessive and unnecessary doses of antibiotics in elective colorectal surgery. Further studies are required to uncover the reasons but lack of appropriate guidelines and failure to exercise evidence-based medicine are major factors that account for this practice. [source]

Evaluation of 280 000 cases in Dutch midwifery practices: a descriptive study

BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 5 2008
MP Amelink-Verburg
Objective, To assess the nature and outcome of intrapartum referrals from primary to secondary care within the Dutch obstetric system. Design, Descriptive study. Setting, Dutch midwifery database (LVR1), covering 95% of all midwifery care and 80% of all Dutch pregnancies (2001,03). Population, Low-risk women (280 097) under exclusive care of a primary level midwife at the start of labour either with intention to deliver at home or with a personal preference to deliver in hospital under care of a primary level midwife. Methods, Women were classified into three categories (no referral, urgent referral and referral without urgency) and were related to maternal characteristics and to neonatal outcomes. Main outcome measures, Distribution of referral categories, main reasons for urgent referral, Apgar score at 5 minutes, perinatal death within 24 hours and referral to a paediatrician within 24 hours. Results, In our study, 68.1% of the women completed childbirth under exclusive care of a midwife, 3.6% were referred on an urgency basis and 28.3% were referred without urgency. Of all referrals, 11.2% were on an urgency basis. The main reasons for urgent referrals were fetal distress and postpartum haemorrhage. The nonurgent referrals predominantly took place during the first stage of labour (73.6% of all referrals). Women who had planned a home delivery were referred less frequently than women who had planned a hospital delivery: 29.3 and 37.2%, respectively (P < 0.001). On average, the mean Apgar score at 5 minutes was high (9.72%) and the peripartum neonatal mortality was low (0.05%) in the total study group. No maternal deaths occurred. Adverse neonatal outcomes occurred most frequently in the urgent referral group, followed by the group of referrals without urgency and the nonreferred group. Conclusions, Risk selection is a crucial element of the Dutch obstetric system and continues into the postpartum period. The system results in a relatively small percentage of intrapartum urgent referrals and in overall satisfactory neonatal outcomes in deliveries led by primary level midwives. [source]

Adverse effects of tocolytic therapy

BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2005
Steve Caritis
The rationale for using tocolytics in preterm labour is to enable transfer of the mother to a tertiary centre and to prolong pregnancy sufficiently so that glucocorticoids can be administered to the mother. There is little question that these short term objectives can be achieved with contemporary tocolytics. Whether tocolytics can maintain pregnancy for sufficient periods to enable in utero maturation to occur remains an unresolved question. When a decision is made to use tocolytics, the clinician is faced with a multitude of choices with side effects, efficacy and ease of administration generally being the most important considerations. Placebo-controlled studies suggest that the ,-agonists, prostaglandin inhibitors and atosiban are effective in prolonging pregnancy for 24,48 hours. Of these three agents, atosiban has the best safety profile. There are no placebo-controlled studies with calcium channel blockers or nitric oxide donors. However, because of their ease of use and efficacy compared with the ,-agonists, calcium channel blockers are widely used. Calcium channel blockers appear to have a better safety profile than the ,-agonists, but there are still significant cardiovascular side effects associated with their use. Indomethacin, although proven to be efficacious, has a safety profile that limits its utility for other than short courses. Magnesium sulphate is the most commonly used tocolytic in the United States, despite a lack of evidence for its efficacy. Although magnesium sulphate appears to have a good safety profile, serious side effects have been reported with its use. The choice of tocolytics is commonly based on personal preference. Whichever tocolytic is chosen, the fundamental parturitional process is not reversed by contemporary treatment, rather a reduction in uterine response to a stimulant; thus, the expectations of tocolytic treatment need to be reconsidered.

Search strategies in decision making: the success of "success"

JOURNAL OF BEHAVIORAL DECISION MAKING, Issue 2 2004
Ben R. Newell
Abstract Examination of search strategies has tended to focus on choices determined by decision makers' personal preferences among relevant cues, and not on learning cue-criterion relationships. We present an empirical and rational analysis of cue search for environments with objective criteria. In such environments, cues can be evaluated on the basis of three properties: validity (the probability that a cue identifies the correct choice if cue values differ between alternatives); discrimination rate (the proportion of occasions on which a cue has differing values); and success (the expected proportion of correct choices when only that cue can be used). Our experiments show that though there is a high degree of individual variability, success is a key determinant of search. Furthermore, a rational analysis demonstrates why success-directed search is the most adaptive strategy in many circumstances. Copyright © 2004 John Wiley & Sons, Ltd. [source]

A typology of motor vehicle consumers using motives for leasing versus financing

JOURNAL OF CONSUMER BEHAVIOUR, Issue 4 2006
Philip J. Trocchia
Previous consumer research suggests that individuals who finance high-cost items tend to differ from those who lease the same items. Some differences are economic, such as income and wealth, while other dissimilarities involve non-economic issues such as personal preferences. We employ non-hierarchical cluster analysis to create consumer segments of motor vehicle lessees and financers based on motives for leasing versus financing and demographics. Five segments were uncovered. Lessees predominate in two categories: budget gourmets and automotive hedonists. Another two categories, utility seekers and basic transportation seekers, are mainly comprised of financers. The final group, mature luxury seekers, consists of a roughly equal mix of lessees and financers. Differences between the segments are addressed here, along with a discussion of findings and implications. Copyright © 2006 John Wiley & Sons, Ltd. [source]

Views of People with Intellectual Disabilities of Their Present and Future Living Arrangements

JOURNAL OF POLICY AND PRACTICE IN INTELLECTUAL DISABILITIES, Issue 3-4 2004
Roy McConkey
Abstract, To determine personal perceptions and preferences of present and potential living arrangements, 180 adults with intellectual disabilities were recruited to participate in 20 focus groups held across Northern Ireland. About half were living with family carers and the balance in a range of other types of accommodations. Verbal probing and video clips were used to elicit views on four different living options (residential homes, small group homes, supported living, and living with a nonrelated family). Four personal preference themes emerged that were common to all participants irrespective of where they lived: having their own bedroom, participating in household activities; having access to community activities, and maintaining contact with family and friends. Adults living on their own or in supported housing valued their independence and having access to support staff, whereas adults living in residential homes spoke of the importance of relationships with co-residents and staff. Overall, most of the adults were content with their present situation, although small group homes and supported living arrangements were the most popular alternatives to living with their families. The discussion group process was useful in eliciting comments and offering participants a chance to reflect on their personal perceptions of housing options. Overall, the findings point to the need for greater consideration of personal preferences in home option choice-making by housing and services providers. [source]

Text-based video content classification for online video-sharing sites

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 5 2010
Chunneng Huang
With the emergence of Web 2.0, sharing personal content, communicating ideas, and interacting with other online users in Web 2.0 communities have become daily routines for online users. User-generated data from Web 2.0 sites provide rich personal information (e.g., personal preferences and interests) and can be utilized to obtain insight about cyber communities and their social networks. Many studies have focused on leveraging user-generated information to analyze blogs and forums, but few studies have applied this approach to video-sharing Web sites. In this study, we propose a text-based framework for video content classification of online-video sharing Web sites. Different types of user-generated data (e.g., titles, descriptions, and comments) were used as proxies for online videos, and three types of text features (lexical, syntactic, and content-specific features) were extracted. Three feature-based classification techniques (C4.5, Naïve Bayes, and Support Vector Machine) were used to classify videos. To evaluate the proposed framework, user-generated data from candidate videos, which were identified by searching user-given keywords on YouTube, were first collected. Then, a subset of the collected data was randomly selected and manually tagged by users as our experiment data. The experimental results showed that the proposed approach was able to classify online videos based on users' interests with accuracy rates up to 87.2%, and all three types of text features contributed to discriminating videos. Support Vector Machine outperformed C4.5 and Naïve Bayes techniques in our experiments. In addition, our case study further demonstrated that accurate video-classification results are very useful for identifying implicit cyber communities on video-sharing Web sites. [source]

Bounded rationality and satisficing in young people's Web-based decision making

Intrinsische Motivation und umweltpolitische Instrumente

PERSPEKTIVEN DER WIRTSCHAFTSPOLITIK, Issue 2 2001
Erik Gawel
In the discussion on the rational choice model of individual behavior, a growing emphasis has recently been placed on the importance of intrinsic motivation. Contrary to assumptions made in the standard economic literature, it is suggested that an individual's motivation to act may not be exclusively determined by external influences (incentives, restrictions) and (given) personal preferences, but, in addition, depends on intrinsically anchored ethical preferences. Intrinsic motivation may diminish if parallel external incentives, such as rewards or orders, come into play: Insofar as external intervention weakens the corresponding intrinsic motivation to act, the (normal) effect of relative prices is opposed by a (countervailing) crowding-out effect of intrinsic motivation. The effect of (over-) crowding-out has been thematized especially in the context of environmental policy. It was suggested that subsidies may support intrinsic incentives whereas taxes and licences (especially though command-and-control measures) tend to undermine them. This paper critically analyzes the impact of intrinsic behavior considerations on the evaluation of environmental policy instruments. It is argued that, if at all, economists' standard recommendations for policy design with respect to subsidies need not be revised even if intrinsic motivation plays any role for the agents' environmental bevavior. Furthermore, command-and-control policy might rather support than weaken intrinsic motivation. [source]

Personality and Politics: Values, Traits, and Political Choice

POLITICAL PSYCHOLOGY, Issue 1 2006
Gian Vittorio Caprara
Voters' political choices have presumably come to depend more on their personal preferences and less on their social characteristics in Western democracies. We examine two aspects of personality that may influence political choice, traits and personal values, using the Five Factor Model of personality traits and the Schwartz (1992) theory of basic personal values. Data from 3044 voters for the major coalitions in the Italian national election of 2001 showed that supporters of the two coalitions differed in traits and values, largely as hypothesized. Center-left voters were higher than center-right voters in the traits of friendliness and openness and lower in energy and conscientiousness. Regarding values, center-left voters were higher than center-right voters in universalism, benevolence, and self-direction and lower in security, power, achievement, conformity, and tradition. Logistic regressions revealed that values explained substantial variance in past and future voting and in change of political choice, trumping personality traits. We discuss explanations for the primacy of values and implications for the social cognitive view of personality. [source]
