Wood is a material often used by architects to enhance the overall ambience of a space, but few researches have been reported to discuss its actual impact on visual impression and luminous effects. This research studies the influence of wood materiality in relation to creating specific lighting ambiances in architecture. In particular, it focuses on the impact of decorative wood indoor panels on the creation of daylighting diversity in interior space and the potential to improve daylighting quality and energy efficiency. The research uses scaled models for their accuracy in rendering complex daylighting ambiances. The photo-luminance meter enables the comparison between different settings of interior spaces created by a selection of wood type materiality: ratio (percentage), colour (Oak, Cape Cod Grey and Dark Walnut coatings) and gloss concerning illuminance patterns obtained from Ecotect software. The CIE L*a*b* colour space is used to classify luminous ambiances. Results indicate that bright colour Oak favours a deeper daylighting penetration and increases the colour temperature of the space by about 300% when applied on the floor. Cape Cod Grey coating provided a neutral colour balance even under sunlighting. High gloss Dark Walnut located on the ceiling produces the highest luminance values, enlarging the window-lighting pattern. The research underlines the role of wood materiality in achieving luminous diversity and creating visually comfortable interior ambiances.

Abstract Quality has been a rallying call in the design and manufacturing world for the last two decades. One way to improve quality is to reduce the impact of manufacturing variation. Variation risk mitigation is challenging especially when a product has multiple quality characteristics and complex production and assembly. It is common wisdom that companies should identify and mitigate the risk associated with variation throughout the design process. As yield problems are identified, they should be mitigated using the most cost effective approach. One approach to variation risk mitigation is variation reduction (VR). VR targets reduction of variation introduced by existing manufacturing processes using tools such as Design of Experiments (DOE) and robust design. Many companies have specialized groups that specialize in these methods. VR teams have the role of improving manufacturing performance; however, these teams are limited in their resources. In addition, no tools exist to quantitatively determine where a VR team’s efforts are most effectively deployed. This paper provides a mathematical and optimization model to best allocate VR resources in a complex product.

Three different types of nanoparticles, 1D Cloisite 30B clay nanoplatelets, 2D halloysite nanotubes (HNTs), and 3D nanobamboo charcoals (NBCs) were employed to investigate the impact of nanoparticle shapes and structures on the material performance of polyvinyl alcohol (PVA) bionanocomposite films in terms of their mechanical and thermal properties, morphological structures, and nanomechanical behaviour. The overall results revealed the superior reinforcement efficiency of NBCs to Cloisite 30B clays and HNTs, owing to their typical porous structures to actively interact with PVA matrices in the combined formation of strong mechanical and hydrogen bondings. Three-dimensional NBCs also achieved better nanoparticle dispersibility when compared with 1D Cloisite 30B clays and 2D HNTs along with higher thermal stability, which was attributed to their larger interfacial regions when characterised for the nanomechanical behaviour of corresponding bionanocomposite films. Our study offers an insightful guidance to the appropriate selection of nanoparticles as effective reinforcements and the further sophisticated design of bionanocomposite materials.

<p><strong>Abstract.</strong> In the community historical objects play the role of witnesses of the past history. This creates an obligation to preserve and reconstruct them for future generations. Photogrammetric methods have been applied for those purposes for many years. In the process of development of inventory documentation, the key aspects related to the selection of appropriate measuring methods for particular objects and the creation of appropriate working conditions. At present, digital measuring techniques allow developing 3D photogrammetric documentation which is particularly valuable both, for conservators of historical objects, as well as for creating virtual museums. Particular attention should be paid to the utilisation of macro photography for that purpose which allows for recreating small fragments of historical details. The objective of this paper is to present possible use of macro photography for inventory of historical patterns engraved in brick walls of one of the cellars of the Royal Castle in Warsaw (Poland); they are called engravings or house marks. The cellar walls were made of bricks (20<span class="thinspace"></span>&amp;times;<span class="thinspace"></span>10<span class="thinspace"></span>cm) on the stone foundations, where a prison was located in the 17th century. Prisoners left their drawings of signs and crests. Bricks are destroyed, some of them are moss-grown, so many engravings are hardly visible and their depths vary between 3 and 5<span class="thinspace"></span>mm. The Canon 5D Mark II camera with the 50 mm macro lens was used to inventory engravings together with the shadow-free flash, mounted on the lens and a special frame with bolts, being the photogrammetric control network. To ensure the high quality of the 3D model, a network of photographs were acquired from two different distances; they were processed with the use of SfM/MVS algorithms implemented in Agisoft PhotoScan software. The aim of this paper is to discusses the impact of selection of control points on the accuracy of the orientation process, the impact of the point cloud density on correct projection of the digital surface, the influence of the DSM resolution on details of projection of shapes and selection of orthorectification and mosaicking parameters on the accuracy of orthoimage generation.</p>

The article is devoted to the study of advertising transformation under the influence of new trends of consumption as a social action. It is highlighted that the current socio-economic situation is creating new subjects for the analysis of already well-known objects. The place and role of advertising in modern society is certainly based on its market principles in the past, but today it is necessary to take into account a set of influencing factors that were previously mutually exclusive but are now indivisible. The greatest influence is exerted by the socio-cultural aspect of consumer behavior, which is based on values and motivators that come from the lifestyle in a qualitatively new external environment. It means that they are not limited to market transactions. Moreover, in today's conditions, social stratification has receded into the background and is not among the main factors of influence. This transformation of understanding the practice of consumption allows to reasonably recruit and use advertising tools to increase their effectiveness. It is determined that during forming an advertising campaign it is necessary to consider the impact on consumer behavior of modern information technology, namely the selection of the necessary information from the large amount that is available. A large amount of information creates an ambiguous situation for the consumer. This requires the integration of advertising tools. It is established that the parallel use of several advertising media allows to carry out the influence similarly to the technology of purposeful management. The availability of technical means that quickly realize the desire can be recommended for both long-term brand communication and for the short term.

Building prototypes is an important part of the concept selection phase of the design process, where fuzzy ideas get represented to support communication and decision making. However, previous studies have shown that prototypes generate different levels of user feedback based on their fidelity and aesthetics. Furthermore, prior research on concept selection has shown that individual risk attitude effects how individuals select ideas, as creative ideas are perceived to be riskier in comparison to less creative ideas. While the role of risk has been investigated in concept selection, there is lack of research on how risk is related to the selection of prototypes at various levels of fidelity. Thus, the purpose of this study was to investigate the impact of prototype fidelity, concept creativity, and risk aversion, on perceived riskiness and concept selection through a between-subjects study with 72 engineering students. The results revealed that there was a “goldilocks” effect in which students choose concepts with “just the right amount” of novelty, not too much and not too little, as long as quality was adequate. In addition, the prototype fidelity of a concept had an interaction with uniqueness, indicating that unique concepts are more likely to be perceived as less risky if presented at higher levels of fidelity.

AbstractSpin-off biotech companies often have difficulties in creating competitive advantage through protection of their intellectual property, due to their limited human and financial resources. Having considered the value of the intellectual property and questions of enforceability, spin-off companies should use patenting only for inventions with a high market value and high patent enforceability; otherwise, publishing early or keeping the invention a trade secret should be preferred. This allows the inventor to benefit from operational freedom while maintaining low costs. The impact of the protected intellectual property on the success of the firm depends on its speed of entry into the market and when it reaches break-even point. In a transition country with a poorly developed entrepreneurial environment, patents may expire before the spin-off company has produced any profit from its expenditures on the protection of the intellectual property. It should also be remembered that their products may contain modules which are already protected by other inventors. Consequently, a strategically fundamental issue for the success of spin-off firms is the careful selection of the markets in which to operate, and the choice of the proper degree and method of intellectual property protection.

The article aims to measure the influence of employee perception of customer power on motives of emotional labour and its impact on outcome of emotional labour. Employee perception about customer power was measured on a 5-point Likert scale from high to low, wherein motives of emotional labour were measured under three categories, namely, prevention motive, instrumental motive and pleasure motive. The study analyses the response of 320 service executives from 5 different type of organizations such as airlines, hotels, nursing homes, insurance companies and banks. The study finds that employee perception about customer power significantly impacts the selection of motive of emotional labour, which in turn was significantly related to the consequences of emotional labour, that is, ‘job burnout’ and ‘job satisfaction’. The study also observes that customer reciprocation towards the display of emotional labour moderates the outcome variables significantly. This study identifies the possible outcomes of emotional labour after taking into consideration the perceived customer power and the moderating role of customer reciprocation. The findings have managerial implications at multiple levels. First of all, organizations may utilize the findings of the reported study to define the display rules that may increase job satisfaction and at the same time reduce job burnout. The study may also be used to provide autonomy to the employees in selecting the motives of emotional labour based on their perception of customer power.

The impact of cybermediaries’ information on Consumer to Consumer (C2C) tax compliance is investigated by using a computational experiment approach and three conclusions are drawn. First, cybermediaries’ information assists tax authorities in selecting audit objects and discovering unregistered taxpayers, and the second signaling role is the main reason for the improvement of the C2C tax compliance rate in the case of low audit probability. Second, the signaling role of cybermediaries’ information is quite limited if the audit probability is low; the increase of the audit probability can directly improve the C2C tax compliance rate as well as indirectly by enhancing the signaling role of cybermediaries’ information; in addition, if the proportion of honest taxpayers is lower than a certain threshold, the lower the proportion is, the lower the signaling role is, ceteris paribus. Finally, the signaling role of cybermediaries’ information on the selection of audit objects rises with the increase of the correlation degree between cybermediaries’ information and taxable income of taxpayers, and a critical value of the correlation degree exists, below which the signaling role of cybermediaries’ information is negative. We also discuss how to enhance the signaling role of cybermediaries’ information to improve the C2C tax compliance rate.

ABSTRACTBacteriocins are an abundant and diverse group of ribosomally synthesized antimicrobial peptides produced by bacteria and archaea. Traditionally, bacteriocin production has been considered an important trait in the selection of probiotic strains, but until recently, few studies have definitively demonstrated the impact of bacteriocin production on the ability of a strain to compete within complex microbial communities and/or positively influence the health of the host. Although research in this area is still in its infancy, there is intriguing evidence to suggest that bacteriocins may function in a number of ways within the gastrointestinal tract. Bacteriocins may facilitate the introduction of a producer into an established niche, directly inhibit the invasion of competing strains or pathogens, or modulate the composition of the microbiota and influence the host immune system. Here we review the role of bacteriocin production in complex microbial communities and their potential to enhance human health.

Purpose The purpose of this paper is to examine the effect of nature of advergame and moderating roles of game-product congruence and need for cognition (NFC) on gamers’ ad-persuasion from attention and elaboration perspectives. Design/methodology/approach A 2 (nature of game: fast or slow)×2 (game-product congruence: high or low)×2 (NFC: high or low) between measures design is used. In total, 224 graduate students participated in the study. A 2×2×2 between subjects ANOVA is used to test the hypotheses. Findings The results show that slow-paced advergames result in high persuasion than fast-paced advergames. A 2 way-interaction indicates that for a slow-paced advergame, low game-product congruence result in high persuasion than in high game-product congruence. Furthermore, findings reveal that for a slow-paced advergame with low game-product congruence, subjects with high NFC report high persuasion than subjects with low NFC. For a fast-paced advergame with low game-product congruence, subjects with high NFC report high persuasion than subjects with low NFC. Practical implications The findings of the study are very important for advertising practitioners as selection of media that fit the advertised product with reference to the content of the media is a planning strategy that has been widely used by media planners. Thus, if high brand recall and recognition is the primary goal for advertisers, then, slow-paced advergames with low-congruent brand placements can be considered a better media strategy for in-game advertising. Furthermore, advertising managers can design advergames by taking into account NFC factor to make sure that the implementation has the strongest positive effect on consumers’ persuasion. Furthermore, advertising managers can design advergames by taking into account NFC factor to make sure that the implementation has the strongest positive effect on consumers’ persuasion. Originality/value This research contributes to the literature of non-traditional online advertising, specifically advergaming context by exploring the impact of nature of game and game-product congruence on gamers’ ad-persuasion. Also, this study is the first attempt toward understanding the moderating role of NFC on gamers’ ad-persuasion in the context of online advertising.
