Taking notes on laptops rather than in longhand is increasingly common. Many researchers have suggested that laptop note taking is less effective than longhand note taking for learning. Prior studies have primarily focused on students' capacity for multitasking and distraction when using laptops. The present research suggests that even when laptops are used solely to take notes, they may still be impairing learning because their use results in shallower processing. In three studies, we found that students who took notes on laptops performed worse on conceptual questions than students who took notes longhand. We show that whereas taking more notes can be beneficial, laptop note takers' tendency to transcribe lectures verbatim rather than processing information and reframing it in their own words is detrimental to learning.

The clinical note documents the clinician’s information collection, problem assessment, clinical management, and its used for administrative purposes. Electronic health records (EHRs) are being implemented in clinical practices throughout the USA yet it is not known whether they improve the quality of clinical notes. The goal in this study was to determine if EHRs improve the quality of outpatient clinical notes.

Counterfeiting is a significant problem for most major currencies and has high social and economic costs. Chemical and physical identifiers that are unique to counterfeit currency are critical to forensic analysis. The 100-yuan Chinese note is mostly red. Here, we analyzed the red ink used in 100-yuan Chinese notes and developed a method to extract and analyze these dyes via high performance liquid chromatography (HPLC) and HPLC/mass spectrometry (MS). We used this approach to analyze the chemical structures of the adulterated colorants from 46 counterfeit 100-yuan notes seized from different locations. The results showed that a variety of inks were found among the seized counterfeit notes from different sources. The chromatographic data signature could be used to clearly discriminate authentic from counterfeit notes, but could also potentially be used to trace the notes to the counterfeiter. To the best of our knowledge, this is the first report to use HPLC/MS to profile red dyes in Chinese currency with important implications for the forensics and law enforcement communities.

Abbreviations are used to improve the speed of note keeping and to simplify patient notes. However studies have shown that they can reduce clarity, increase mistakes and cause confusion in management plans. Our review highlights the misuse of abbreviations in surgical note keeping.

Many analytical or cell culture procedures require homogeneous starting cell populations that cannot be obtained directly from organ dissection. Here, we describe two enrichment procedures to achieve this goal and discuss their respective advantages in specific experimental contexts. Notes in this chapter include some tips on how to determine the appropriate level of purity (see Note 1 ).

There is increasing recognition of sex/gender differences in health and the importance of identifying differential effects of interventions for men and women. Yet, to whom the research evidence does or does not apply, with regard to sex/gender, is often insufficiently answered. This is also true for systematic reviews which synthesize results of primary studies. A lack of analysis and reporting of evidence on sex/gender raises concerns about the applicability of systematic reviews. To bridge this gap, this pilot study aimed to translate knowledge about sex/gender analysis (SGA) into a user-friendly ‘briefing note’ format and evaluate its potential in aiding the implementation of SGA in systematic reviews.

Popular culture insists on the significance of suicide notes, but research has yielded conflicting results about who leaves notes. Utilizing 6 years of suicides from a comprehensive statewide data surveillance system, differences were examined between cases with suicide notes and those without in terms of demographics, circumstances of the suicide, and precipitating circumstances. Of the 2,936 suicides, 18.25% included a note. Demographics and circumstances did not differ for cases with a note compared to cases with no note. Results have implications for working with people bereaved by suicide in helping understand that the notes are uncommon and not systematic. However, it is also possible that for some individuals, the content of a note is meaningful and can help or hinder their course of bereavement.

The outpatient clinical note documents the clinician’s information collection, problem assessment, and patient management, yet there is currently no validated instrument to measure the quality of the electronic clinical note. This study evaluated the validity of the QNOTE instrument, which assesses 12 elements in the clinical note, for measuring the quality of clinical notes. It also compared its performance with a global instrument that assesses the clinical note as a whole.
