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
deïŹning 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 difïŹcult to compare or generalize ïŹndings 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 ïŹrst part of the review, by disentangling the interpretations of the concept, we
show that dominant logic consists of four deïŹning 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 ïŹrm's dominant logic.
Thus, our main contribution is a clariïŹcation 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 within the handbag approach, which we assume
to be the dominant mechanism at energies well above the production threshold

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 â one of the key sectors from the point of view of GHG emissions and energy intensity â 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 â 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 â 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 âScience Citiesâ 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 lithiumâbased red pyrotechnic colorants. We have previously shown lithium dihydrobis(azolyl)borates to be promising candidates due to their favorable adjustment to a reductive and lowâtemperature 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 1Hâtetrazole and 1Hâpyrazole with nitro or amino groups, respectively, tailors the oxygen balances of the resulting Lewis acid base adducts to enhance the fuelârich flame environment or to make them oxidizing agents. This work determines whether the lithium salts of dihydrobis(3ânitropyrazolâ1âyl)borate and dihydrobis(5âaminotetrazolâ1âyl)borate are suitable replacements for strontiumâcontaining color imparters. Furthermore, the influence of potentially greenâlightâproducing 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
