    1. Many hospitalists have added value as local leaders in quality improvement, safety, and innova-tion, but some have functioned more as shift workers. For exam-ple, many community hospital-ists have a 7-days-on, 7-days-off schedule that focuses mainly on high-volume clinical work and sends an unspoken but clear mes-sage that, at the end of an inten-sive clinical “on” stint, one is “off ” and uninvolved. Our impression is that hospitalist programs pro-vide more value when hospital-ists’ inpatient assignments (clini-cal “systole”) are complemented by a systems-oriented “diastole,” dur-ing which clinical activity is limit-ed but they contribute to key in-stitutional programs. Productive diastole is more likely when hos-pitalists have strong leadership, a robust professional-development curriculum, and a mutual hospi-tal–hospitalist commitment to adding value during specified and structured nonclinical time.

      The hospitalists patient is the hospital

    1. Tại Việt Nam, Tổ chức Y tế thế giới (WHO) coi ô nhiễm không khí là một trong những nguyên nhân gây ra gánh nặng bệnh tật và tử vong hàng đầu. Có khoảng 6/10 bệnh có tỷ lệ chết cao nhất tại Việt Nam là những bệnh liên quan đến không khí.
      
    2. Tuy nhiên, việc sử dụng khẩu trang chỉ là một giải pháp tình thế. Theo TS Hoàng Dương Tùng, để hạn chế ô nhiễm bụi PM2.5 cần hướng tới giải quyết tận gốc. Nguyên nhân gây ra ô nhiễm bụi mịn PM2.5 được xác định từ các nguồn sản xuất, giao thông, xây dựng, sinh hoạt... Trong đó bốn ngành gồm sắt thép, nhiệt điện, xi măng, hóa chất đã gây ra 80% lượng ô nhiễm từ các nguồn ô nhiễm điểm.

    1. A promising approach that addresses some worker output issues examines the way that workers do their work rather than the output itself, using machine learning and/or visualization to predict the quality of a worker’s output from their behavior [119,120]

      This process improvement idea has some interesting design implications for improving temporal qualities of SBTF data: • How is the volunteer thinking about time? • Where does temporality enter into the data collection workflow? • What metadata do they rely on? • What is their temporal sensemaking approach?

    2. Of the research foci, quality control has arguably received the most attention so far. Approaches for quality control largely fall into two camps: up-front task design and post-hoc result analysis. Task design aimsto design tasks that are resistant to low-quality work.

      Quality control processes is definitely a tension for SBTF.

      A better integrated task design and verification process at the end of activations could be more effectively address information quality concerns.

    3. Unlike traditional organizations in which workers possess job security and managers can closely supervise and appropriately reward or sanction workers, or distributed computing systems in which processors are usually highly reliable, crowd work poses uniquechallenges for both workers and requestersranging fromjob satisfactiontodirection-setting, coordination, and quality control.

      In the literature, quality tends to be used as an attribute of the output (content, HIT, etc.) but could/should it also refer to the crowd worker experience, as Kittur notes: "job satisfaction, direction-setting, coordination, and quality control"?

      How are these factors incorporated into the process and incentive system?

    1. A more fruitfulapproach considers variation in peer production success to understand whenand where it works better and worse.

      Benkler's examples of quality studies of large peer groups seems focused on community evaluation of the output rather than what constitutes a high-performing community (process) or a quality values (norms).

      Note: He cover process and norms several paragraphs later.

    2. Although this hasconstituted an inconvenient fact in peer production practice, it also reflects animportant opportunity for future research. By focusing only on the projectsthat successfully mobilize contributors, researchers interested inwhenpeerproduction occurs or the reasonswhyit succeeds at producing high qualityoutputs have systematically selected on their dependent variables. An impor-tant direction for peer production research will be to study these failures.

      Failed peer production projects offer potentially interesting insights and should be studied.

    3. Infollowing these three paths, scholars have begun to consider variation withinpeer production projects to understand when and why peer production leadsto different kinds of high quality outputs

      Recent quality studies have explored projects that: • have not attracted sufficiently large communities to wash out bias/inaccuracies, • large communities that have not functioned to create quality information, • different measures/definitions of quality

    4. Recent work hasbegun to probe more deeply into different dimensions along which qualitycan be conceptualized and measured. This new scholarship has given rise toa more nuanced understanding of the different mechanisms through whichhigh quality resources arise, and founder, in peer production.

      Benkler notes that output "quality" was the focus of early research and has evolved to exploring how it is "conceptualized and measured." Defining and understanding information quality is also connected to my crowdsourcing work.

      However, I'm curious if quality studies also look at the process, in addition to the output.

    1. Sixty-three percent of respondents judged the overall quality of their open textbook to be above average or excellent, with an additional 33% rating it as average. Only 3.5% of the sample rated their open textbook below average in quality (see Figure 4).
    1. Negative values included when assessing air quality In computing average pollutant concentrations, EPA includes recorded values that are below zero. EPA advised that this is consistent with NEPM AAQ procedures. Logically, however, the lowest possible value for air pollutant concentrations is zero. Either it is present, even if in very small amounts, or it is not. Negative values are an artefact of the measurement and recording process. Leaving negative values in the data introduces a negative bias, which potentially under represents actual concentrations of pollutants. We noted a considerable number of negative values recorded. For example, in 2016, negative values comprised 5.3 per cent of recorded hourly PM2.5 values, and 1.3 per cent of hourly PM10 values. When we excluded negative values from the calculation of one‐day averages, there were five more exceedance days for PM2.5 and one more for PM10 during 2016.

    1. Beta blockers have long been associated with sleep disturbances such as difficulty falling asleep, staying asleep, and insomnia. They have been shown to reduce the production of melatonin via specific inhibition of beta-1 adrenergic receptors. Melatonin is a hormone secreted by the pineal gland in the brain, and helps in maintaining normal circadian rhythms.6,20-21 People with hypertension already have a lower melatonin production rate than those with normal blood pressure.22

      The question becomes, then, do beta blockers impair sleep when exogenous melatonin is administered concurrently?

    1. It's not uncommon for people to hold the idea that being "old" is related with low life quality. This thought brings people the idea that comparing with the younger generation, the old don't necessary need much care or even don't deserve using much social resource, because they are just "dying" in whatever way. Thus I think it's important to let people understand that old people can also have a life with high quality, thus it deserves us to work on that.

    1. China has slapped millions of dollars worth of fines on alleged offenders for violating anti-pollution rules, according to state media.

      Worth noting that another motivation for innovation is the growing repricusions of the externalities of legacy industries and companies. This is encouraging investment in sustainable solutions and opening the door for new way business who's costs are lower becuase their impact on the environment is lower.

    1. Without a presence of poverty in their lives, politicians don’t come to witness or understand the realities on the ground—and perplexingly, few observers seem to advocate that this needs to change.

      QUALITY

      Statement of consequences: if not corrected, politicians do not grasp the realities.

    2. Consequently, America’s political elite is often woefully out of touch with economic reality for those living in poverty—or even those struggling to stay out of it.

      QUALITY Statement of quality: the outcome of these issues are that politicians are cleally out of touch with the poor they represent.

      • How frequently do laws and legislation effectively correct issues of poverty?
      • Would more be possible if representatives were more economically divers?
    3. We can’t expect effective and humane policy without representatives who understand, witness, and investigate the experience that they control.

      QUALITY Statement identifying that without remedy policy and situations will not change.

      Publication indicators as proxies for quality. Despite the many problems with peer review, publication indicators are used to evaluate Scholars for hiring promotion, finding, and other Rewards. Weather appropriate or not, outputs of the system in the form of data, documents, and Publications are easier to measure than are the inputs such as Scholars time, education, reading of scholarly literature, and research activities in their Laboratories and libraries. More time in the laboratory or in the library does not necessarily translate into more or better research, for example. While it is understandable that the recognition of Scholars should be based heavily on quality assessments of their scholarly contributions to their fields, it is essential to distinguish clearly between quality of scholarship and the use of indicators such as the publication form and citation counts as proxies for quality.

    1. Put simply, various stakeholders seem to have different perspectives on how research assessment works currently and how it should work in the future. In order to move forward, we must first identify and then address a number of misunderstandings.

      This might be of interest, a project that we've put together for the Scholarly Communication Institute this year titled "The Qualities of Quality – Validating and justifying digital scholarship beyond traditional values frameworks": http://trianglesci.org/2015/05/15/the-qualities-of-quality/
