We develop a model of sequential search when the cost of searching in each period is stochastic and show that in this setting optimal search entails delay when the cost of searching is high. This characterizes the fact that search activity is often intermittent. Furthermore, we show that if an individual has present-biased preferences this will lead to procrastination, i.e. non-optimal delay th...

Decisional procrastination has been one of the main phenomena analysed in university students, together with self-efficacy, during COVID-19 pandemic. We examined roles academic self-efficacy and intolerance uncertainty on decisional 318 Italian students. Furthermore, mediating role relationships between was explored. The Academic Self-Efficacy Scale, Procrastination Intolerance Uncertainty Scal...

We describe an efficient local multiple alignment filtration heuristic for identification of conserved regions in one or more DNA sequences. The method incorporates several novel ideas: (1) palindromic spaced seed patterns to match both DNA strands simultaneously, (2) seed extension (chaining) in order of decreasing multiplicity, and (3) procrastination when low multiplicity matches are encount...

Computer science faculty members cite procrastination as one of the key causes of poor student performance in programming projects. In contrast, students cite conflicting demands for time. This study uses a tool-driven process of automated compilation and testing of student programs to collect student-project data. Data include when, for how long, how often, and with what magnitude of effort an...

Borrowing from Cognitive Heierarchy Theory, I introduce bounded rationality into the β, δ model of present-biased preferences. I define a level-two agent—or “k-2– sophisticate”—as one who is aware that her future selves will have present-bias, but believes that they will be naive. The k-2–sophisticate does one round of strategic thinking about her future behavior instead of the unlimited number...

Few of learners cannot complete their academic tasks not because that they are unintelligent or dull, however postponement in completion and it is due to procrastination. This research study focused on exploring meta-cognitive awareness procrastination its effect students’ achievement. Quantitative approach with survey technique was employed. Sample comprised 700 students studying at undergradu...

Procrastination is an increasingly prevalent phenomenon. Although research suggests smartphones might be involved, little known about the momentary association between different patterns of smartphone use and procrastination. In a preregistered study, 221 students ( M age = 20, 55% female) self-reported procrastination five times day for 30 days (i.e., experience sampling method) while their wa...

ôbjective: âpproximately 66-80%of graduate students experience statistics anxiety and some researchers propose that many students identify statistics courses as the most anxiety-inducing courses in their academic curriculums. âs such, it is likely that statistics anxiety is, in part, responsible for many students delaying enrollment in these courses for as long as possible. this paper proposes ...
