Objective: We performed the eco-hygienic assessment of electromagnetic fields as an environmental factor under modern conditions. Materials and methods: We determined a range of issues on the significance of electromagnetic fields of various frequencies and intensities in human vital activity on the basis of the analysis of scientific literature. Results and discussion: Taking into account the further development of the national economy of the country, safety and protection of the population from the effects of electromagnetic fields both in industry and everyday life remain one of the urgent problems, taking into consideration that their biological effect on the human organism is very complex and has not been completely studied. In this regard, special attention should be paid to the use of hand-held telephones and computers which are used by the people of different age, gender and physiological state of the organism. Therefore, the existing protection measures against the negative effect of EMF require further improvement and refinement. Conclusions: Protection of the population from the adverse effects of electromagnetic radiation of various frequencies and intensities has been and remains an urgent eco-hygienic problem of mankind, and medical workers, engineers, biologists, ecologists and other specialists should participate in its solution.

Sexual Encounters

Sexual interactions have a potent influence on health in several species, including mammals. Previous work in C. elegans identified strategies used by males to accelerate the demise of the opposite sex (hermaphrodites). But whether hermaphrodites evolved counter-strategies against males remains unknown. Here we discover that young C. elegans hermaphrodites are remarkably resistant to brief sexual encounters with males, whereas older hermaphrodites succumb prematurely. Surprisingly, it is not their youthfulness that protects young hermaphrodites, but the fact that they have self-sperm. The beneficial effect of self-sperm is mediated by a sperm-sensing pathway acting on the soma rather than by fertilization. Activation of this pathway in females triggers protection from the negative impact of males. Interestingly, the role of self-sperm in protecting against the detrimental effects of males evolved independently in hermaphroditic nematodes. Endogenous strategies to delay the negative effect of mating may represent a key evolutionary innovation to maximize reproductive success.

Purpose The authors wanted to find out if hiring temporary staff at busy A&E departments had a negative impact on the work of permanent staff. Design/methodology/approach They did semi-structured interviews with managers and permanent staff at two London NHS hospitals with different policies for hiring temps. Hospital A prioritized the use of NHS professions for its bank and agency nurses, as well as doctors and locums. Hospital B focused more on using its own internal bank staff as temps. Findings The findings showed the generally negative effect of using temporary staff on permanent staff. But the reaction of permanent staff depended on the type of temporary staff. More experienced temps could generally be trusted to get on with the job, whereas the inexperienced ones required more supervision. Originality/value The authors proposed an approach to improved practice beginning with “macro-level managers” who could maintain service quality as a higher priority than contracting costs. They could also encourage permanent staff to do occasional temporary shifts. The co-authors also felt that “meso-level managers” could be given the role of hiring “preferred temps” where possible.

Point Of Reference

High-frequency electromagnetic fields can have a negative effect on both the human body and electronic devices. The devices and systems utilized in radio communications constitute the most numerous sources of electromagnetic fields. The following research investigates values of the electric component of electromagnetic field intensification determined with the ESM 140 dosimeter during the flights of four aircrafts—Cessna C152, Cessna C172, Aero AT3 R100, and Robinson R44 Raven helicopter—from the airport in Depultycze Krolewskie near Chelm, Poland. The point of reference for the obtained results were the normative limits of the electromagnetic field that can affect a pilot in the course of a flight. The maximum value registered by the dosimeter was E = 3.307 V/m for GSM 1800 frequencies.

The Cost

Purpose While common sense suggests that corruption will likely have a negative impact on the economy as it raises the cost of doing business, research on the topic showed inconsistent results (positive, negative and neutral). This paper aims to verify whether corruption has a “grease” or “sand” effect on the wheels of entrepreneurial rates and under which conditions corruption will have stronger or weaker effects. Design/methodology/approach Using institutional theory as the basis for the hypotheses, generalized least squares estimation is conducted to empirically examine the role of corruption and political discretion in entrepreneurship in a sample of 93 countries. Findings Countries with higher levels of corruption are associated with lower levels of firm creation. However, this negative effect of corruption is weaker when there are higher levels of political discretion. Originality/value This is the first evaluation of the moderating effect of political discretion on the negative impact of corruption on entrepreneurship.

Clinical Problems

The working alliance has been recognized as a predictor of psychotherapy outcome across therapeutic orientations. Despite mixed findings regarding the effect of problem severity on the alliance formation, there is evidence suggesting that therapist factors may interfere in this association. This study examined how clients baseline clinical features affected the early alliance and the possible role of therapists countertransference management as a mediator. Thirteen therapeutic dyads were assessed at 2 different time points. Clients clinical dimensions were assessed prior to the 2nd session, and therapists countertransference management and clients ratings of the alliance were measured after the 2nd session. Positive associations were found between clients subjective wellbeing, social functioning, risk, and global psychological distress and countertransference management dimensions and total score. Empathy-based countertransference management suppressed the negative impact of clinical risk on alliance. Our findings suggest that clinical problems activate countertransference management, which in turn may buffer their negative effect on alliance.

PurposeThe purpose of this study is to examine the effects of brand origin (BO) misperception (hereafter BOM) or non-identification on brand equity. Besides, the current study investigates the moderating role of brand strength in the relationship between BOM and brand equity.Design/methodology/approachThe current study adopted a 4 (BO identification: favorable BOM vs adverse BOM vs non-identification vs correct identification) × 2 (brand strength: strong vs weak) between-subjects design. A total number of 547 participants performed assessments on the automotive brand. The current study selected three strong brands and three weak brands for tests. In the experiment, respondents had to associate the brand with its country of origin. The assignment of BO conditions was based upon respondents' natural responses provided. ANOVA was used for data analysis.FindingsThe results indicate that as compared to correct BO identification, BOM (either adverse or favorable) or non-identification exerts a more negative impact on brand equity. Moreover, the study demonstrates that brand strength moderates the effect of perceived BO on brand equity.Originality/valueThis study provides empirical support to the notion that BOM is detrimental to brand equity. Specifically, when adverse BOM occurs, a strong brand suffers more from the negative consequences resulted than a weak brand does. Conversely, when consumers misattribute the BO to a country with a stronger image than its real origin (i.e. favorable BOM), the resulting negative effect is reversed. Moreover, the non-identification of BO hurts the brand equity of both strong and weak brands.

One of the side effects of each electrical device work is the electromagnetic field generated near its workplace. All organisms, including humans, are exposed daily to the influence of different types of this field, characterized by various physical parameters. Therefore, it is important to accurately determine the effects of an electromagnetic field on the physiological and pathological processes occurring in cells, tissues, and organs. Numerous epidemiological and experimental data suggest that the extremely low frequency magnetic field generated by electrical transmission lines and electrically powered devices and the high frequencies electromagnetic radiation emitted by electronic devices have a potentially negative impact on the circadian system. On the other hand, several studies have found no influence of these fields on chronobiological parameters. According to the current state of knowledge, some previously proposed hypotheses, including one concerning the key role of melatonin secretion disruption in pathogenesis of electromagnetic field induced diseases, need to be revised. This paper reviews the data on the effect of electric, magnetic, and electromagnetic fields on melatonin and cortisol rhythms—two major markers of the circadian system as well as on sleep. It also provides the basic information about the nature, classification, parameters, and sources of these fields.
