The odor microclimate is formed by gaseous airborne components perceived either as an unpleasant smell or as a pleasant smell. Smells enter the building interior partly from outdoors (exhaust fumes - flower fragrance) and partly from indoors (building materials, smoking cigarettes - cosmetics, dishes). They affect the human organism through the olfactory center which is connected to the part of brain that is responsible for controlling people’s emotions and sexual feelings: smells therefore participate to a high level in mood formation. The sense of smell diminishes slowly in people over the age of 60, but all female age categories have a better sense of smell than males. Smell is extremely sensitive, e.g., during pregnancy, or if an illness is coming. Bad smells cause a decrease in human performance, loss of concentration, and loss of taste. Sweet smells have a positive impact on human feelings and on human performance. Criteria for odor microclimate appraisal are presented (concentration limits of CO2 , TVOC, plf, decipol, decicarbdiox, decitvoc).

Purpose Many construction businesses are currently building and keeping social media pages for their enterprises to be visible to the public to improve their social interaction, promote business interest, build trust and relationships with their targeted audience on social media. The purpose of this study is to examine the impact of social mediausage on performance of construction businesses (CBs) in Abuja, Nigeria. Design/methodology/approach This study used a quantitative research approach by identifying constructs that reveal three aspects of organisation’s physiognomies that impact the process of espousing, implementing and using technological innovations in conducting businesses. Well-structured questionnaire was used to obtain data from 113 purposively sampled building materials’ merchant operating in Dei-Dei Market, Abuja, Nigeria. This study used partial least squares structural equation modelling technique to establish the relationship among the constructs. Findings The results of this study indicated that technology has significant relationship with social media adoption, whereas social media adoption has a very strong positive impact on organisation’s performance (P < 0.001) with respect to improved customer relations and services and enhanced information accessibility. Research limitations/implications This study has implications for CBs that wish to adopt social media to promote their businesses by presenting to them the opportunity to understand the impact of technology, environment and organisational potential in improving business performance. This study is cross-sectional in nature, and this calls for caution in interpreting the results. Originality/value This paper developed and tested a conceptual framework presented to understand the interrelationships amongst the constructs, which would be of great significance to business owners in developing their social interaction and promote business interest via social media. The outcome of this research is beneficial to researchers to further study how the different social media tools could help in influencing business decisions.

Few studies have been conducted on whether the coexistence of green innovation and corporate social responsibility (CSR) has a favorable interaction effect on firm value. This interaction effect is of great significance for enterprises balancing resource allocation between two factors in the future. Meanwhile, information disclosure can reflect the efforts of enterprises in taking on CSR. Therefore, taking China’s listed companies as an example, this paper studies the interaction effect of CSR after being divided into the three different dimensions of environment, society, and governance (ESG) and green innovation on firm value. The quantile regression method can reflect the impact of CSR and green innovation on the firm value of different levels. The study finds that: (1) green innovation can promote the improvement of medium- and high-level firm value; (2) only the disclosure of environmental and social information can have a positive impact on firm value; (3) the interaction effect between green innovation and social disclosure on firm value is a substitution effect, which will gradually weaken with the increase of firm value. This paper proposes that relevant departments should guide green funds into enterprises with capital constraints to alleviate the issue of fund crowding into CSR and green innovation.

Objective The study addresses the impact of time pressure on human interactions with automated decision support systems (DSSs) and related performance consequences. Background When humans interact with DSSs, this often results in worse performance than could be expected from the automation alone. Previous research has suggested that time pressure might make a difference by leading humans to rely more on a DSS. Method In two laboratory experiments, participants performed a luggage screening task either manually, supported by a highly reliable DSS, or by a low reliable DSS. Time provided for inspecting the X-rays was 4.5 s versus 9 s varied within-subjects as the time pressure manipulation. Participants in the automation conditions were either shown the automation’s advice prior (Experiment 1) or following (Experiment 2) their own inspection, before they made their final decision. Results In Experiment 1, time pressure compromised performance independent of whether the task was performed manually or with automation support. In Experiment 2, the negative impact of time pressure was only found in the manual but not in the two automation conditions. However, neither experiment revealed any positive impact of time pressure on overall performance, and the joint performance of human and automation was mostly worse than the performance of the automation alone. Conclusion Time pressure compromises the quality of decision-making. Providing a DSS can reduce this effect, but only if the automation’s advice follows the assessment of the human. Application The study provides suggestions for the effective implementation of DSSs in addition to supporting concerns that highly reliable DSSs are not used optimally by human operators.

The purpose of this publication is to study the system of economic security parameters and improve the process of using RADAR logic as an element of assessing the information security of the enterprise. The importance of the concept of economic security of enterprises (EBP) is that scientists recognize it as an important factor in national security, since the real economy is an environment of planning, organization and the best use of resources. Four main factors of EBP are considered: a) planning; b) monitoring of the external and internal environment; (b) identifying and implementing threat response measures; d) control and improvement of the system. Taking into account the turbulence of the external environment, the impact on the formation of parameters of the EBP of macro-, meso- and microeconomic level factors is investigated. It is proposed to lay the methodology based on the model of the European Quality Management Fund (EFQM) as the basis for the formation of the EBP culture. Its goal is to achieve a high level of business excellence, the direction is to promote the processes of coordination of business and security goals, coordination of efforts to achieve sustainable security indicators, the formation of market knowledge and best practices for their exchange. The prospects for practical use of the EFQM model, the components of which are: basic concepts of perfection are carefully studied; criteria; RADAR logic. The conclusion about the feasibility of implementing the RADAR system is substantiated. Full and comprehensive implementation of the system can have a positive impact on the level of short-term liquidity of the company's assets, its long-term solvency, the formation of the desired level of profitability for shareholders, and generate positive external effects for society and the environment. The complexity of ensuring the EBP is explained by the variety of manifestations and relationships of interactive elements among the internal components of enterprises and the unpredictability of the manifestation of external factors. A logical conclusion is drawn about the importance of the EBP concept, its ability to include a significant number of factors in the sphere of management influence. The direct consequences of using the EBP concept are the comprehensive provision of both its own economic security and the fundamental principles of its organization, the safety of the activities of individuals, the ability to take into account numerous factors in the formation of the actual level of regional, national and international economic security of the state. The strategic directions of further research are outlined: study, schematization, numerical formalization of system-structural relations of components and threats to economic security of enterprises, the real sector and the national economy as a whole.

Due to the phenomenal growth of e-commerce, online shopping has recently become a worldwide trend. This fosters many online shopping platforms to enter into Asian emerging markets, which evolves a need to understand online decision-making processes in this particular context. Addressing this gap, our study initialized an integrated framework based on Uses and Gratification theory and the Cognitive–Affect–Behavior paradigm to examine the impact of gratification elements on customer satisfaction and convenience enforcing continuance shopping intention. Moreover, we also conceptualize the moderating role of online ratings in our study. In total, 317 valid questionnaires from Pakistani online shoppers were incorporated to statistically test our model using the Structural Equation Modeling (SEM) approach in Amos. Besides, the results confirm the positive impact of layout and functionality on customer satisfaction and convenience, while the impact of PEEIM has been found insignificant. Furthermore, customer satisfaction and convenience are found to be the imperative predictors of continuance shopping intention. Our findings exhibit that a high level of online rating strengthens the direct effect of satisfaction and convenience on continuance intention. Theoretical and practical implications for future scholars and e-commerce shopping platforms are discussed.

The paper presents an overview of the most important regulations and institutions affecting the level of quality and fittingness of the vehicle fleet, in order to increase the level of general traffic safety in the Republic of Serbia. The Traffic Safety Agency, among other things, alone or in cooperation with others, regulates, controls and implements the system of homologation, testing and control of conformity of vehicles, equipment and parts. It authorizes and supervises other organizations for vehicle control and testing. The role of standardization in this process is dual: first - it refers to the subject of testing - vehicles, and second - to the quality of testing - authorized organizations. The paper discusses the important provisions of regulations for vehicle testing and analyzes the impact of the standards ISO 17020 and ISO 17025 on the work of authorized organizations. In conclusion, it was proposed that in order to achieve and maintain high level of testing quality, mandatory accreditation of authorized organizations should be prescribed. Mandatory application of the standards would have a positive impact on the traffic safety segment which depends on the technical characteristics of the vehicle, and as well, reduce the Agency's obligations.

This research evaluates the impact of ICT on the technical efficiency of firms in 63 provinces and cities in Vietnam. We apply to use the DEA method in which we use the variable return to scale to evaluate because firm sizes in 63 provinces are different. At the same time, this method aims to minimize input factors without reducing output factors to measure technical efficiency. This result that is used a binary variable in the logit regression model to identify factors that have an impact on technical efficiency, especially the ICT factor. The research results show that only nearly 10% of the provinces could be technically efficient in business activities. Provinces with sustainable performance and efficiency all depend on influencing factors such as equity ratio, labor productivity, market size, investment, and especially the ICT factor keep increasing over the years and fluctuate around a pretty high level. On the other hand, for the group of unsustainable and ineffective provinces, these variables tend to decrease and fluctuate around at a low level. The research shows that factors in labor productivity, equity ratio, market size, investment, and ICT all have a positive impact on a firm’s performance in 63 provinces and cities of Vietnam. Therefore, firms that want to enhance their efficiency need to have strategies to improve the factors mentioned above. Moreover, the local government needs to improve the ICT index to help to increase their local Enterprises’ efficiency.
