Three Issues with the State of People and Workplace Analytics

People and workplace analytics is a hype topic. It depicts information systems and processes for data-driven decisionmaking that concern people-related organizational outcomes. The topic is driven by practitioners with only scarce academic backing. We outline three challenges for the field of people and workplace analytics: first, ambiguity in definitions and conceptions, second, sparse research as well as a lack of scientific evidence for the espoused value propositions, and third, a lack of strong theoretical foundation. To address these challenges, we propose a categorization schema, grounded in existing research on management information systems and tailored to people and workplace analytics. The schema helps to identify the prevalent conceptions on people and workplace analytics, and to clarify the elicited gaps in understanding

The Bacterial Flora of the Antecubital Fossa: The Efficacy of Alcohol Disinfection of this Site, the Palm and the Forehead

The surface flora of the antecubital fossa (ACF) of 25 subjects comprised the same kinds of bacteria as are commonly found on the hands, arms, back and forehead. The population density was bimodal. Fifteen subjects had a sparse flora. After alcohol disinfection there were no surviving bacteria on these subjects. The other 10 subjects had a more abundant flora (310 to 10,000 per cm2) and after alcohol treatment there remained on 9 of these subjects a surviving population showing no quantitative correlation with the surface flora.On the palm (hypothenar eminence) of 5 subjects all bacteria were eliminated by alcohol disinfection despite initial surface populations equal to those of the 5 ACF subjects with the greatest alcohol resistant flora. On the forehead, bacterial population densities were much greater than on the palm or ACF. Alcohol disinfection reduced the surface population on the average, more than the subsurface populations, but did not eliminate either propionibacteria or gram positive cocci.Five ACF subjects with the highest alcohol resistant populations in the initial survey were retested several times over 7 mo (1 subject) or 2½ yr (4 subjects). On each person, the surviving bacteria in the initial test were of one particular species, Propionibacterium acnes, Peptococcus saccharolyticus, Staphylococcus epidermidis or an aerobic diphtheroid. In subsequent tests, S. epidermidis disappeared but the other 4 organisms continued to be present as alcohol resistant populations on both arms of their respective subjects throughout the study (22 of 25 tests positive).We suggest that the terms sheltered and exposed flora would be more accurate than transient and resident in discussing skin disinfection

Dynamic Race Prediction in Linear Time

Writing reliable concurrent software remains a huge challenge for today's programmers. Programmers rarely reason about their code by explicitly considering different possible inter-leavings of its execution. We consider the problem of detecting data races from individual executions in a sound manner. The classical approach to solving this problem has been to use Lamport's happens-before (HB) relation. Until now HB remains the only approach that runs in linear time. Previous efforts in improving over HB such as causally-precedes (CP) and maximal causal models fall short due to the fact that they are not implementable efficiently and hence have to compromise on their race detecting ability by limiting their techniques to bounded sized fragments of the execution. We present a new relation weak-causally-precedes (WCP) that is provably better than CP in terms of being able to detect more races, while still remaining sound. Moreover it admits a linear time algorithm which works on the entire execution without having to fragment it.Comment: 22 pages, 8 figures, 1 algorithm, 1 tabl

Protein and Lysine Contents of Endosperm and Bran of the Parents and Progenies of Crosses of Common Wheat

Grain samples from parent and progeny rows of the common wheat (Triticum aestivum L.) crosses, \u27Nap Hal\u27/ \u27Atlas 66* and Nap Hal/\u27Super X\u27, were fractionated into their starchy endosperm and bran components to determine the within-kernel site of their variation in protein and lysine concentration. Nap Hal and Atlas 66 are highprotein wheats. Nap Hal also has elevated grain lysine content. Super X has average protein and lysine content. Transgressive segregation existed both for high and low endosperm protein concentration among the F3 progeny rows of Nap Hal/Atlas 66. Low-protein progeny rows had endosperm protein percentages that were 3 to 5 percentage points lower than the parental mean (19.5%). High-protein progeny lines were 2 to 4 percentage points higher than the parental mean. Nap Hal and some of the progeny rows were 5 percentage points higher in bran protein content than Atlas 66. Endosperm and bran protein percentages of Nap Hal/Super X F4 progeny were within the parental range. Some progeny rows had endosperm and bran protein concentrations equal to those of Nap Hal. Variation among the progeny rows for endosperm and bran lysine (% of protein) concentrations was within the range of variability of the replicated parental rows. Variation for grain protein content among the progeny rows of both crosses was due to variation for both endosperm and bran protein content. Variation for grain lysine (% of sample) among the Nap Hal/Atlas 66 progeny rows was due primarily to variation in endosperm and bran protein content with endosperm and bran lysine (% of protein) being of lesser importance

Behaviour of factors II, VII, IX and X in bleeding complications during long-term treatment with Coumarin

In 20 patients suffering from bleeding complications during long-term treatment with phenprocoumon, the depression of the activity of Factors II, VII, IX and X, on the average, was found to be stronger than in so-called adequately treated patients, whereas no statistically significant differences could be demonstrated between the average activity of the 4 factors. The individual variations between the 4 factors were higher than those found in normal individuals and adequately treated patients. Thrombotest activity appeared to be considerably lower than the average factor activity. This discrepancy is mainly caused by the action of the recently discovered circulating anticoagulant occurring in coumarin-treated or vitamin K-deficient patients
