Clarifying the Dominant Logic Construct by Disentangling and Reassembling its Dimensions

Since its introduction, Prahalad and Bettis's concept of dominant logic has informed a variety of scholarly conversations in management and strategy research. However, scholars have interpreted dominant logic in different ways, emphasizing different aspects, such as managerial mindsets, administrative tools and management functions, as defining elements. Similarly, empirical studies have captured various aspects, such as meanings of entrepreneurs, observable strategic decisions and business model similarity, as indicators of dominant logic. Consequently, the concept lacks analytical clarity, and it is difficult to compare or generalize findings from this diverse set of studies. The aim of this review is to improve conceptual clarity by analysing, comparing and evaluating the existing interpretations and assessments of dominant logic in 94 studies. In the first part of the review, by disentangling the interpretations of the concept, we show that dominant logic consists of four defining dimensions: (i) shared mental models; (ii) values and premises; (iii) organizational practices; and (iv) organizing structures. In the second part, we reassemble dominant logic into an integrative model and theorize about how these dimensions operate in concert to produce a firm's dominant logic. Thus, our main contribution is a clarification and synthesis of the literature, which comes with implications on how future research can conceptualize and operationalize dominant logic more consistently

Hard exclusive photoproduction of charmed mesons

{We investigate the photoproduction process $p \gamma \rightarrow \Lambda_{c}^{+} \overline{D^{0}}$ within the handbag approach, which we assume to be the dominant mechanism at energies well above the production threshold and in the forward scattering hemisphere.Comment: proceedings of Photon 2013, May 20-24 2013, Paris, Franc

Good management improves productivity, but it may worsen environmental performance

The reduction of greenhouse gas (GHG) emissions is an increasingly important policy objective for many governments, both in developed and developing economies. This is reflected, among other things, in the emergence of energy efficiency as a high-priority topic on the policy agenda. In manufacturing – one of the key sectors from the point of view of GHG emissions and energy intensity – improvements in energy efficiency can come about from upgrading or closing existing plants or adding new production capacity that uses more modern technology. Moreover, recent research has found that management practices – such as those focused on how a firm handles a process-related problem, collection of production indicators, the timescale and difficulty of its targets and incentives – also play a significant role in reducing the energy intensity of firms

The Long Run Effects of R&D Place-based Policies: Evidence from Russian Science Cities

We study the long run effects of a unique historical place-based policies targeting R&D: the creation of “Science Cities” in former Soviet Russia. The establishment of Science Cities and the criteria for selecting their location were largely guided by political and military-strategic considerations. We compare current demographic and economic characteristics of Science Cities to those of appropriately matched localities that were similar to them at the time of their establishment. We find that in the modern Russian economy, despite the massive cuts of governmental support to R&D that followed the dissolution of the USSR, Science Cities host more high-skilled workers and more developed R&D and ICT sectors; are the origin of more international patents; and generally appear to be more productive and economically developed. Within a spatial equilibrium framework, we interpret these findings as the result of the interaction between persistence and agglomeration forces. Furthermore, we rule out alternative explanations that have to do with the differential use of public resources, and we find limited support for a case of equilibrium reversion. Finally, by analyzing firm-level data we obtain evidence in favor of spillover effects with a wide spatial breadth

Comparison of Functionalized Lithium Dihydrobis(azolyl)borates with Their Corresponding Azolates as Environmentally Friendly Red Pyrotechnic Coloring Agents

The recent awareness of the impact of strontium on health has stimulated research efforts on lithium‐based red pyrotechnic colorants. We have previously shown lithium dihydrobis(azolyl)borates to be promising candidates due to their favorable adjustment to a reductive and low‐temperature flame atmosphere. These compounds are assumed to be sufficiently stable only if the pKa values of the heterocycles are between 5 and 20. Apart from their acidities, functionalization of 1H‐tetrazole and 1H‐pyrazole with nitro or amino groups, respectively, tailors the oxygen balances of the resulting Lewis acid base adducts to enhance the fuel‐rich flame environment or to make them oxidizing agents. This work determines whether the lithium salts of dihydrobis(3‐nitropyrazol‐1‐yl)borate and dihydrobis(5‐aminotetrazol‐1‐yl)borate are suitable replacements for strontium‐containing color imparters. Furthermore, the influence of potentially green‐light‐producing boron is evaluated by comparing the emissions of the lithium borates and the corresponding lithium azolates

Lock-in detection for pulsed electrically detected magnetic resonance

We show that in pulsed electrically detected magnetic resonance (pEDMR) signal modulation in combination with a lock-in detection scheme can reduce the low-frequency noise level by one order of magnitude and in addition removes the microwave-induced non-resonant background. This is exemplarily demonstrated for spin-echo measurements in phosphorus-doped Silicon. The modulation of the signal is achieved by cycling the phase of the projection pulse used in pEDMR for the read-out of the spin state.Comment: 4 pages, 2 figure

Bridging with Veno-Arterial Extracorporeal Membrane Oxygenation in Children: A 10-Year Single-Center Experience

Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is frequently used in children with and without congenital heart disease (CHD). This study, of a single-center and retrospective design, evaluated the use and timing of V-A ECMO in a pediatric cohort who underwent V-A ECMO implantation between January 2009 and December 2019. The patients were divided into a pre-/non-surgical group and a post-surgical group. Among the investigated variables were age, gender, weight, duration of ECMO, ECMO indication, and ventricular physiology, with only the latter being statistically relevant between the two groups. A total of 111 children (58 male/53 female), with a median age of 87 days (IQR: 7-623) were supported using V-A ECMO. The pre-/non-surgical group consisted of 59 patients and the post-surgical group of 52 patients. Survival at discharge was 49% for the pre-/non-surgical group and 21% for the surgical group (p = 0.04). Single-ventricle physiology was significant for a worse outcome (p = 0.0193). Heart anatomy still has the biggest role in the outcomes of children on ECMO. Nevertheless, children with CHD can be successfully bridged with ECMO to cardiac operation
