abstract = {This article discusses microlevel actions undertaken by owner?managers, and how such actions affect stakeholders in enhancing the sustainability of small and medium enterprises (SMEs), the knowledge on which is lacking in the extant literature. The paper, by adopting an inductive analytical approach, draws key insights from the literature on microfoundations and sustainability and evidence from representatives of 5 Cultural and Creative Industry SMEs in Italy and of 5 in the United Kingdom. The findings suggest that owner?managers play a crucial role when engaging in sustainability activities jointly with employees and other stakeholders, through which individual?level actions enhance collective organizational?level sustainability practices. The U.K. and Italian cases highlight 2 contrasting approaches to dealing with sustainability; thus, the paper contributes to the emerging literature on SME microfoundations and sustainability.},

abstract = {By underlining the relevance of the use of ICTs, knowledge sharing and electronic markets for SMEs, it emerges the need for stimulating a debate on digitisation process of supply chain management (SCM). Electronic infrastructure in the service sector are reducing each kind of cost and improving multiply buyer-supplier relationships, facilitating negotiations and transactions. However, since the coordination costs are still high, the use of ICTs is limited. This phenomenon thus attracts the interests of scholars and practitioners. Although it still needs to further investigate. Especially, the optimal use of ICTs within SMEs' SCM have not been studied yet. Therefore, by leveraging on four proxies: ICTs specialised human resources, knowledge sharing activities, buyer-supplier relationships, adoption of electronic markets this optimal was analysed via structural equation modelling based on a sample of 1254 SMEs operating in the service sector in Italy.},

As the technical substrate is the physical medium in which the innovation materializes, we analyze its role in this process. Our research is based on a longitudinal analysis of management innovation in a large industrial group. We demonstrate that the creation of managerial innovation rests on a strong interaction between the technical substrate and a managerial philosophy. The legitimate rise of new actors, integrated in a new relationship system thanks to managerial innovation, reinforces the appropriation process.},

abstract = {A method is proposed to compute the response of highly heterogeneous structures by constructing homogenized models when no scale separation can be assumed. The technique is based on an extended homogenization scheme where the averaging operators are replaced by linear filters to cut off fine scale fluctuations, while maintaining locally varying mechanical fields with larger wavelength. As a result, the constitutive law at an intermediate scale, called mesoscale, arises to be naturally nonlocal by construction, where the kernel operator is fully constructed by computations on the unit cell associated with the microstructure.},

A partir d'une démarche abductive, nous montrons que la mise en place de collectifs de femmes, dans la phase ante-création, est génératrice de confiance en soi. Le caractère bienveillant, empathique et non compétitif du groupe exclusivement féminin facilite, pour certaines femmes candidates à la création, la déconstruction de stéréotypes de genre sur l'entrepreneuriat féminin et atténue le sentiment de culpabilité lié à la difficulté à concilier projet entrepreneurial et vie familiale. En d'autres termes, la participation de la femme potentiellement créatrice à un collectif féminin répond à un besoin psychologique d'approbation externe qui peut faire défaut, notamment au sein de la famille. Toutefois, la pratique de l'accompagnement collectif au féminin dans la phase ante-création présente certaines limites. Ces dernières résultent de l'importance accordée par certaines femmes à la mise en place d'un environnement mixte pour le partage d'expériences entrepreneuriales diverses et le développement de réseaux d'affaires.},

abstract = {Nowadays, dental numerical controlled (NC) milling machines are available for dental laboratories (labside solution) and dental production centers. This article provides a mechanical engineering approach to NC milling machines to help dental technicians understand the involvement of technology in digital dentistry practice. The technical and economic criteria are described for four labside and two production center dental NC milling machines available on the market. The technical criteria are focused on the capacities of the embedded technologies of milling machines to mill prosthetic materials and various restoration shapes. The economic criteria are focused on investment cost and interoperability with third-party software. The clinical relevance of the technology is discussed through the accuracy and integrity of the restoration. It can be asserted that dental production center milling machines offer a wider range of materials and types of restoration shapes than labside solutions, while labside solutions offer a wider range than chairside solutions. The accuracy and integrity of restorations may be improved as a function of the embedded technologies provided. However, the more complex the technical solutions available, the more skilled the user must be. Investment cost and interoperability with third-party software increase according to the quality of the embedded technologies implemented. Each private dental practice may decide which fabrication option to use depending on the scope of the practice.},

abstract = {As is the case in the field of medicine, as well as in most areas of daily life, digital technology is increasingly being introduced into dental practice. Computer-aided design/ computer-aided manufacturing (CAD/CAM) solutions are available not only for chairside practice but also for creating inlays, crowns, fixed partial dentures (FPDs), implant abutments, and other dental prostheses. CAD/CAM dental practice can be considered as the handling of devices and software processing for the almost automatic design and creation of dental restorations. However, dentists who want to use dental CAD/CAM systems often do not have enough information to understand the variations offered by such technology practice. Knowledge of the random and systematic errors in accuracy with CAD/CAM systems can help to achieve successful restorations with this technology, and help with the purchasing of a CAD/CAM system that meets the clinical needs of restoration. This article provides a mechanical engineering viewpoint of the accuracy of CAD/ CAM systems, to help dentists understand the impact of this technology on restoration accuracy.},

abstract = {Statement of problem. Computer-aided design/computer-aided manufacturing (CAD/CAM) machining influences the surface roughness of dental restorations and tool wear. Roughness must be suitable to meet clinical requirements, and the tool must last as long as possible. Purpose. The purpose of this pilot study was to investigate the influence of the CAD/CAM toolmaterial couple on tool wear and surface roughness after milling. Material and methods. Three tools (Lyra conical tool Ø1 mm; GACD SASU, Lyra conical tool Ø1.05 mm; GACD SASU, and Cerec cylinder pointed tool 12S; Sirona Dental Systems GmbH) and 3 CAD/CAM materials (Lava Ultimate; 3M ESPE, Mark II; VITA Zahnfabrik H. Rauter GmbH, and Enamic; VITA Zahnfabrik H. Rauter GmbH) were tested. The tool wear of 6 tool-material couples at a feed rate of 2 m/min was analyzed before and after 8 minutes of flank and climb milling with optical and scanning electron microscopy (SEM) observations and tool weighing. The surface roughness after milling was observed for 9 tool-material couples for flank and climb milling. Feed rates of 1, 2, 3, and 4.8 m/min were used for each couple. Ra, Rt, Rz, Sa, Sq, and Sz roughness criteria were measured. A paired comparison of tool-material couples was conducted with the Kruskal-Wallis test. Results. The Mark II material led to more severe tool wear. Milling of Lava Ultimate resulted in chip deposits on the tool grit. The Cerec cylinder pointed tool 12S was less worn for each material tested. The Cerec cylinder pointed tool 12S and the Lyra conical tool Ø1.05 mm provided similar roughness measurements for the 3 materials tested. The Lyra conical tool Ø1.05 mm tool provided better roughness than the Lyra conical tool Ø1 mm tool for the Enamic material. Conclusion. Tool lifetime calculated by volume of milled material removed should be the measure

provided by CAD/CAM manufacturers instead of a number of blocks. This tool lifetime should be

provided for the milling conditions associated with the material milled. Material hardness and tool grit are key factors for achieving a given roughness.},

The purpose of this work is to investigate the residual stress distribution induced by laser shock process-

ing in a 2050-T8 aeronautical aluminium alloy with both X-ray diffraction measurements and 3D finite

element simulation. The method of X-ray diffraction is extensively used to characterize the crystallo-

graphic texture and the residual stress crystalline materials at different scales (macroscopic, mesoscopic

and microscopic).

Shock loading and materials' dynamic response are experimentally analysed using Doppler velocimetry

in order to use adequate data for the simulation. Then systematic experience versus simulation compar-

isons are addressed, considering first a single impact loading, and in a second step the laser shock

processing treatment of an extended area, with a specific focus on impact overlap. Experimental and

numerical results indicate a residual stress anisotropy, and a better surface stress homogeneity with

an increase of impact overlap.

A correct agreement is globally shown between experimental and simulated residual stress values,

even if simulations provide us with local stress values whereas X-ray diffraction determinations give

averaged residual stresses.},

abstract = {The success of related diversification is not a given. Although synergies between a firm's businesses may exist, problems can arise in the sharing of key resources and capabilities as the firm attempts to exploit the synergies. To achieve success in related diversification, firms often leverage their organizational slack, or resources and capabilities that are in excess of the level demanded by their normal operations. However, sharing is difficult when firms have insufficient organizational slack, and this can lead to an overstretching of shared resources. Through case study methodology, this paper investigates how one technological SME managed its limited organizational slack while engaged in related diversification. Particular attention is given to the mechanisms that contribute to diversification failure. Consideration is also given to how the capability life-cycle may affect capability sharing in related diversification efforts.},
