This article highlights the analysis of available data about the impact of food additives on a human body. We specified the meaning of the term "food additives", paid attention to the history of discovering and applying food additives, described the differences between natural and synthetic food additives. According to the literature, most food additives used in modern food industry can be considered quite safe. The safety of food additives is determined on the basis of extensive comparative studies, and the use of food additives is prohibited unless they have been tested and approved by the relevant authorities. But, with the development of analytical methods, the emergence of new experimental data, the question of the possible negative impacts of one or another additive on individual organs and systems of the human body can be reconsidered. In particular, certain food additives that were previously considered harmless, for example E 240, E 121, are now recognized as very dangerous and prohibited for use. It has been proven that food supplements that are harmless to one person can have a negative effect on another. Therefore, it is recommended to limit the use of food additives for children, the elderly and people prone to allergic reactions. The article describes in detail the results of experimental studies about the negative impact of specific additives, in particular ponceau 4R, sodium nitrite and monosodium glutamate on individual internal organs. Attention is focused on the group of food additives such as nitrogen compounds, which due to the biotransformation can result in the nitrite formation. An excess of the latter, in turn, according to some researchers, can provoke the development of malignant tumours in various organs, primarily in the terminal parts of the colon. Thus, the impact of various combinations of food additives on the morpho-functional state of the internal organs requires further detailed research.

Purpose This study aims to examine gender differences in the impact of imagining product use on purchase decisions. The authors argue that while imagination can enhance purchase intention for female consumers, it can be detrimental to male consumers. This study explores the conditions under which imagination can be turned into a positive device for male consumers. Design/methodology/approach Three experimental studies were conducted. The first two studies illustrate the differential effects of imagination on males vs females. Given the negative effect found among males, the third study focused exclusively on male consumers to identify conditions under which the negative impact of imagination on these consumers can be alleviated. Findings Studies 1 and 2 show that while an imagination tactic has positive or no effect on female consumers, a generic imagination request lowers male consumers’ purchase intention. Focusing on potential ways of alleviating this negative effect, Study 3 shows that for males without prior brand ownership experience, imagining product use in a less-typical context can increase purchase intention. Research limitations/implications The results provide evidence that gender impacts the effectiveness of imagination in improving product evaluation. Furthermore, the context of imagination and previous brand experience can be used together to determine how male consumers respond to imagination. Practical implications The study’s findings warn against the blind use of imagination tactics. Instead, retailers need to customize imagination tactics based on gender, previous brand experience and product usage context. Originality/value To the best of the authors’ knowledge, this is one of the first papers to examine the impact of gender on the influence of imagination on product evaluation.

BACKGROUND Cell phone use brought convenience to people, but using phones for a long period of time or in the wrong way and with a wrong posture might cause damage to the human body. OBJECTIVE To assess the impact of improper cell phone use on transport and chronic injuries. METHODS Studies were systematically searched in PubMed, EMBASE, Cochrane, and Web of Science up to April 4, 2019 and relevant reviews were searched to identify additional studies. A random-effects model was used to estimate the overall pooled estimates. RESULTS Cell phone users were at a higher risk for transport injuries (RR: 1.37, 95%CI: 1.221.55), long-term use of cell phones increased the transport injury risk to non-use or short-term use (RR: 2.10, 95% CI: 1.632.70). Neoplasm risk caused by cell phone use was 1.07 times that of non-use (95% CI: 1.011.14); Compared with non-use, cell phone use had a higher risk of eye disease, with a risk of 2.03 (95% CI: 1.273.23), the risk of mental disease was 1.26 (95% CI: 1.171.35), the risk of neurological disorder was 1.16 (95% CI: 1.021.32), and a pooled risk of other chronic injuries was 1.20 (95% CI: 0.981.59). CONCLUSIONS Cell phone use at inappropriate situations has a negative impact on the human body. Therefore, it is necessary to use cell phones correctly and reasonably.

BACKGROUND: China’s atmospheric PM2.5 pollution is serious, and PM2.5 exerts a negative impact on the human respiratory system, cardiovascular, and mental health, and even more serious health risk for the elderly with weak immunity. OBJECTIVE: This work aims to analyse the impacts of PM2.5 microenvironment exposure on the health of the elderly and provide corresponding countermeasures. METHODS: The survey subjects are 118 retired elderly people in the community. PM2.5 exposure concentrations are monitored in summer (June 10 ∼ July 10, 2019) and winter (November 25 ∼ December 25, 2019). RESULTS: The exposure concentration in winter is higher than that in summer, with statistical difference (P <  0.05). Under the impact of PM2.5 microenvironment exposure, smoking in the elderly can increase the concentration of PM2.5, and long-term exposure to PM2.5 in the elderly can cause mental health problems. CONCLUSION: Long-term exposure of the elderly to the PM2.5 microenvironment leads to physical diseases and even psychological problems, which requires attention.

Purpose Time pressure is the most common kind of work pressure that employees face in the workplace; the existing research results on the effect of time pressure are highly controversial (positive, negative, inverted U-shaped). Especially in the era of knowledge economy, there remains a research gap in the impact of time pressure on individual knowledge hiding. The purpose of this paper is to explore the impact of different time pressure (challenge and hindrance) on knowledge hiding and to explain why there is controversy about the effect of time pressure in the academics. Design/methodology/approach The authors collected two waves of data and surveyed 341 R&D employees in China. Moreover, they used regression analysis, bootstrapping and Johnson–Neyman statistical technique to verify research hypotheses. Findings The results show that challenge time pressure (CTP) has a significant negative effect on knowledge hiding, whereas hindrance time pressure (HTP) has a significant positive effect on knowledge hiding; job security mediates the relationship between time pressure and knowledge hiding; temporal leadership strengthen the positive impact of CTP on job security; temporal leadership can mitigate the negative impact of HTP on job security. Originality/value The findings not only respond to the academic debate about the effect of time pressure and point out the reasons for the controversy but also enhance the scholars’ attention and understanding of the internal mechanism between time pressure and knowledge hiding.

The article describes a laboratory study of nematocidal properties of flavourings with antibacterial effect against Ascaris suum (Goeze, 1782) and Trichuris suis Schrank, 1788. In the experiments, eight concentrations of food additives with antibacterial properties were used: cinnamaldehyde, benzoic acid, formic acid, linalool, citral, β-ionone. Minimum LC50 value for eggs of A. suum was observed while using cinnamaldehyde and benzoic acid – 1.62 ± 0.37% and 1.69 ± 0.14%, and for eggs of T. suis – 0.57 ± 0.03% and 1.80 ± 0.11% respectively. The lowest influence on the development of eggs of nematodes of pigs’ A. suum and T. suis was exerted by formic acid, linalool, citral and β-ionone. In eggs of A. suum and T. suis, larvae formed in 21 and 50 days even during exposure to 3% emulsions of these substances. The strongest negative impact on the eggs of parasitic nematodes was displayed by cinnamaldehyde flavouring. Further study on nematocidal properties of flavourings, as well as their mixtures, would contribute to the development of preparations which would have a strong effect on eggs and larvae of nematodes of animals and humans.

Abstract: Filtering respiratory protection devices are widely used in industry and now in healthcare. The tests that these products undergo assess only the technical characteristics, without considering how the personal protective equipment affects the physiological processes of the user. The purpose of this study was to study modern methods of physiological assessment of the negative impact of the use of filtering respiratory protection devices on the human body. Analyzed domestic and foreign publications. The absence of a unified set of physiological methods for assessing the impact of filtering means of personal respiratory protection on the employee's body was established. This may be due to insufficient actualization of this problem both in Russia and in foreign countries.

PurposeThe mechanism of marketing strategy style and its impact on firms are research issues received wide attention. In particular, the aggressive style of marketing strategy has been chosen by many companies, but recent studies have shown that it has a negative effect on corporate performance. This leads to the core issue of this paper – does the aggressive style of marketing strategy always had a negative impact on corporate performance? Are there any factors that can alleviate this negative impact?Design/methodology/approachBased on the resource-based theory and agency theory, this paper takes the Growth Enterprise Market (GEM) listed companies as the research objects, collects secondary data and conducts the research by regression model.FindingsThe empirical research shows that: (1) the aggressive style of marketing strategy significantly and negatively affects the performance of firm; (2) the resource constraint can moderate the main effect and resource control play a weak adjustment role.Practical implicationsIn practice, this paper confirms the adverse impact of aggressive style of marketing strategy on the performance of listed companies on GEM and inspires the industry to strengthen the control and supervision of marketing resources.Originality/valueThis paper makes up for the research gap in the field of cross-research in finance and marketing theoretically.

Abstract Background Cell phone use brought convenience to people, but using phones for a long period of time or in the wrong way and with a wrong posture might cause damage to the human body. This study was designed to assess the impact of cell phone use on transport and chronic injuries.Methods Studies were systematically searched in four database and relevant reviews were searched to identify additional studies. A total of 41 studies met the inclusion criteria.Results Cell phone users were at a higher risk for transport injuries (RR: 1.37, 95%CI: 1.22−1.55), long-term use of cell phones increased the transport injury risk to non-use or short-term use (RR: 2.10, 95% CI: 1.63−2.70). Neoplasm risk caused by cell phone use was 1.07 times that of non-use (95% CI: 1.01−1.14); Compared with non-use, cell phone use had a higher risk of eye disease, with a risk of 2.03 (95% CI: 1.27−3.23), the risk of mental disease was 1.26 (95% CI: 1.17−1.35), the risk of neurological disorder was 1.16 (95% CI: 1.02−1.32), and a pooled risk of other chronic injuries, was 1.20 (95% CI: 0.98−1.59). Subgroup analyses found that motor crashes had significantly increased (OR: 1.25; 95%CI: 1.18−1.32), as well as the risk for hearing problems (OR: 4.54; 95%CI: 3.29−5.80), headaches (OR: 1.25; 95%CI: 1.18−1.32), and abnormal biochemical indicators (OR: 0.51; 95%CI: 0.04−0.99).Conclusions Cell phone use at inappropriate situations has a negative impact on the human body. Therefore, it is necessary to use cell phones correctly and reasonably.

Hierarchical loyalty programs award elevated customer status (e.g., “elite membership”) to consumers who meet a predefined spending level. However, if a customer subsequently falls short of the required spending level, firms commonly revoke that status. The authors investigate the impact of such customer demotion on loyalty intentions toward the firm. Building on prospect theory and emotions theory, the authors hypothesize that changes in customer status have an asymmetric negative effect, such that the negative impact of customer demotion is stronger than the positive impact of status increases. An experimental scenario study provides evidence that loyalty intentions are indeed lower for demoted customers than for those who have never been awarded a preferred status, meaning that hierarchical loyalty programs can drive otherwise loyal customers away from a firm. A field study using proprietary sales data from a different industry context demonstrates the robustness of the negative impact of customer demotion. The authors test the extent to which design variables of hierarchical loyalty programs may attenuate the negative consequences of status demotions with a second experimental scenario study and present an analytical model that links status demotion to customer equity to aid managerial decision making.
