New state of play in information systems research: the push to the edges

Abstract: The dominant way of producing knowledge in information systems (IS) seeks to domesticate high-level reference theory in the form of mid-level abstractions involving generic and atheoretical information technology (IT) components. Enacting such epistemic scripts squeezes IS theory to the middle range, where abstract reference theory concepts are directly instantiated or slightly modified to the IS context, whereas IT remains exogenous to theory by being treated as an independent variable, mediator, or moderator. In this design, IT is often operationalized using proxies that detect the presence of IT or its variation in use or cost. Our analysis of 143 articles published in MIS Quarterly and Information Systems Research over the past 15 years demonstrates that over 70 percent of published theory conforms to this mode of producing IS knowledge. This state of play has resulted in two negative consequences: the field (1) agonizes over the dearth of original and bold theorizing over IT and (2) satisfices when integrating theory with empirics by creating incommensurate mid-range models that are difficult to consolidate. We propose that one way to overcome these challenges is to critically examine and debate the negative impacts of the field's dominant epistemic scripts and relax them by permitting IS scholarship that more fluidly accommodates alternative forms of knowledge production. This will push IS inquiry to the "edges" and emphasize, on the one hand, inductive, rich inquiries using innovative and extensive data sets and, on the other hand, novel, genuine, high-level theorizing around germane conceptual relationships between IT, information and its (semiotic) representations, and social behaviors. We offer several exemplars of such inquiries and their results. To promote this push, we invite alternative institutionalized forms of publishing and reviewing. We conclude by inviting individual scholars to be more open to practices that permit richer theorizing. These recommendations will broaden the field's knowledge ecology and permit the creation of good IS knowledge over just getting "hits." We surmise that, if such changes are carried out, the field can look confidently toward its future as one of the epicenters of organizational inquiry that deal with the central forces shaping human enterprise in the 21st century.

A set of simple-sequence repeat (ssr) markers covering the prunus genome

Abstract: A set of 109 microsatellite primer pairs recently developed for peach and cherry have been studied in the almond × peach F2 progeny previously used to construct a saturated Prunus map containing mainly restriction fragment length polymorphism markers. All but one gave amplification products, and 87 (80%) segregated in the progeny and detected 96 loci. The resulting Prunus map contains a total of 342 markers covering a total distance of 522 cM. The approximate position of nine additional simple sequence repeats (SSRs) was established by comparison with other almond and peach maps. SSRs were placed in all the eight linkage groups of this map, and their distribution was relatively even, providing a genome-wide coverage with an average density of 5.4 cM/SSR. Twenty-four single-locus SSRs, highly polymorphic in peach, and each falling within 24 evenly spaced approximately 25-cM regions covering the whole Prunus genome, are proposed as a 'genotyping set' useful as a reference for fingerprinting, pedigree and genetic analysis of this species.

Grb 080913 at redshift 6.7

Abstract: We report on the detection by Swift of GRB 080913, and subsequent optical/near-infrared follow-up observations by GROND, which led to the discovery of its optical/NIR afterglow and the recognition of its high-z nature via the detection of a spectral break between the i' and z' bands. Spectroscopy obtained at the ESO-VLT revealed a continuum extending down to lambda = 9400 angstrom, and zero flux for 7500 angstrom< lambda < 9400 angstrom, which we interpret as the onset of a Gunn-Peterson trough at z = 6.695 +/- 0.025 (95.5% confidence level), making GRB 080913 the highest-redshift gamma-ray burst (GRB) to date, and more distant than the highest-redshift QSO. We note that many redshift indicators that are based on promptly available burst or afterglow properties have failed for GRB 080913. We report on our follow-up campaign and compare the properties of GRB 080913 with bursts at lower redshift. In particular, since the afterglow of this burst is fainter than typical for GRBs, we show that 2 m class telescopes can identify most high-redshift GRBs.

Optimal load distribution for two industrial robots handling a single object

Abstract: The load distribution problem for two coordinating industrial robots handling a single object is studied. When two industrial robots grasp a single object, the total number of degrees of freedom is usually greater than six. Thus, the joint torques of two robots for a required motion of the object is not unique. The redundant degrees of freedom may be used to optimize certain kind of performance. The least energy consumption is selected as the optimization criterion. Optimal algorithms without and with a bound on the joint torques are investigated. The results show that the algorithms are computationally complicated and not suitable for real-time applications. Alternatively, optimal algorithms are proposed for load distribution with minimum exerted forces on the object. These algorithms require less computational time, which makes them attractive for real-time applications. >
