A Response to Honig and Samuelsson (2014)
No full textHonig and Samuelsson (2014) recently published an article in this outlet criticizing “Does business planning facilitate the development of new ventures? “ a paper I wrote with Scott Shane nearly 15 years ago. They claim that their effort adds to the discussion of (a) the merits of business planning, (b) data replication and extension, (c) sample selection bias, (d) evaluation of normative research and (e) publication standards. However, most of the claims they make are incorrect

Cognition in myotonic dystrophy type 1: a 5-year follow-up study
No full textBackground and purpose: Studies on cognitive decline in myotonic dystrophy type 1 (DM1) are characterized by conflicting results. The purpose of the present study was to analyse possible decline in classical/adult onset DM1 at a 5-year follow-up and to explore the correlation with disease-related and demographic factors. Methods: Patients with DM1 (n = 37) were examined with a comprehensive neuropsychological test battery yielding measures on memory, attention, verbal, visuospatial and executive functions. Assessment of muscle impairment and CTG repeat expansion size was performed. Results: A majority of the participants (65%) performed worse at follow-up. Compared to normative data, patients scored significantly worse on tests measuring memory, attention, visuospatial construction and verbal ability. Neither CTG repeat size nor muscle impairment related to cognitive decline. However, age at onset and disease duration were correlated with the number of tests in which performance was below 1 SD at both baseline and follow-up examination. Conclusions: Measurements show that classical/adult onset DM1 is characterized by cognitive decline. Both earlier onset and longer duration of the disease are indicative of more cognitive deficits.
Benchmark data – biofilm fouling experiments on dissolved oxygen sensors
No full textThe dataset contain experimental data from dissolved oxygen sensors in water resource recovery facilities (WRRFs), evaluated in (Samuelsson et al. 2018). Data from both clean and fouled (both artificially fouled with grease and real biofilm fouling) oxygen sensors have been recorded. Data from the phenomena when the sensor signals temporally changes during automatic air-cleaning cleaning (denoted impulse response) are stored separately.Benchmark data from article “Fault signatures and bias progression in DO-sensors, Water Science and Technology (2018)”. The dataset contain experimental data from dissolved oxygen sensors in water resource recovery facilities
Quantitative evaluation of microplankton palaeobiogeography in the Ordovician-Early Silurian of the northern Trans European Suture Zone: implications for the timing of the Avalonia-Baltica collision
No full textQuantitative analysis of assemblage similarity among chitinozoan and acritarch associations recovered from various sedimentary sequences across the Trans European Suture Zone (TESZ: southern Baltic Sea and northern Germany region), permits evaluation of changes in microplankton palaeobiogeography during the Ordovician in the study area. The present data confirm strong palaeobiogeographic differences between the lower Ordovician of the Rugen area, and the coeval domains of the East European Platform (EEP), corroborating the idea that the subsurface of Rugen should be considered palaeogeographically as the eastern extension of Avalonia. Cluster analysis of chitinozoan assemblages from numerous wells in the Rugen area, and one well from the southern margin of the EEP indicates that chitinozoan bioprovincialism reached its maximum during the Llanvirn; during this period, the Rugen microplankton communities were clearly Gondwanan in character. Calculations using the coefficient of similarity support the conclusion of a high similarity between Llanvirn acritarch assemblages from the Rugen subsurface and from coeval Perigondwana localities (e.g. Tunisia). Since the early Caradoc, this Gondwanan affinity of the Rugen microfossils starts to lessen, and becomes negligible during the late Caradoc. During latest Caradoc-early Ashgilll through Llandovery times the chitinozoan assemblages from either side of the TESZ are undistinguishable. If palaeobiogeographical differentiation is primarily related to palaeolatitudinal distance, then the present data support closure of the Tornquist Ocean during late Caradoc-Ashgill times. The presence of reworked Llanvirn acritarchs of Perigondwanan affinity in middle Ashgill sedimentary sequences at the southern margin of the EEP, clearly shows that by this time erosion of an uplifted area was taking place. Accordingly, the closure of the Tornquist Ocean, and consequent Avalonia-Baltica collision must have taken place during the time interval between the middle Caradoc and the early middle Ashgill (Rawtheyan). New chitinozoan data from boreholes H 2 and K 5, offshore of Rugen Island, northern Germany, allow for precise biostratigraphic dating. In the pre-Devonian part of H 2, Siphonochitina formosa indicates an Abereiddian (Early Llanvirn) age, facilitating correlation with boreholes Binz 1/73 and Lohme 2/70 of Rugen. In borehole K 5, the occurrence of Belonechitina robusta and Tanuchitina bergstroemi permits attribution of the investigated pre-Carboniferous sequence to the middle-late Caradoc, and, possibly, early Ashgill.
