Wage Differences between Polish and Romanian Intra-EU Migrants in a Flexi-Secure Labour Market: An Over-Time Perspective

By merging longitudinal register data and a customised survey, this article explores whether sectoral segmentation, migrants’ pre- and post-migration human capital and social structures, shape wages of Polish and Romanian long-term migrants to Denmark. Pronounced wage differences in favour of Polish migrants are evident in the first two years in Denmark, notwithstanding the same regulatory context under the free movement of labour in the EU. Wage differences persist – albeit at a considerably lower level – throughout the eight-year period, mainly because of significant sectoral segmentation. Sectoral segmentation not explained by demographics, pre-migration human capital or crisis effects, might indicate categorical stereotyping by employers. Regarding (co-ethnic) social networks, at least for the early stages of migration, the study does not find significant effects on wages. While the evidence shows a positive return on wages of formal higher education taken post migration, this is not the case for further training and Danish language education.

Polarity Asymmetry in Lightning Return Stroke Speed Caused by the Momentum Associated with Radiation

In positive lightning return strokes, the net momentum transported by the radiation field has the same direction as the momentum associated with electrons, whereas the momentum associated with electrons is in opposite direction to the momentum of radiation in negative return strokes. It is shown here that this polarity asymmetry could limit the maximum speed of positive return strokes with respect to the negative return strokes.

The importance of incorporating relevant-added value into esports sponsorships

PurposeThis research aims to identify how important it is that brands incorporate relevant-added value into their esports sponsorships.Design/methodology/approachThis exploratory research applied a convergent-parallel mixed method with equal status. Data were collected by interviewing 22 experts in esports sponsorships and having 5,638 esports fans fill out an online survey. SPSS 25 was used to analyze quantitative data and NVIVO 10 to process qualitative data. Each dataset was analyzed separately and then compared with both having the same level of importance.FindingsThe results revealed that all experts considered the creation of relevant-added value as an essential strategy for successful esports sponsorships and the large majority of fans want sponsors to apply this tactic. Interestingly, while the experts mostly emphasized ways to directly benefit the fan-base, the fans prefer that sponsors focus on directly supporting the esports industry.Practical implicationsBrands should incorporate relevant-added value into their esports sponsorships as it greatly decreases fan resistance to the promotional message, catches the fans' attention and engagement much more easily, has a much higher probability of leading to high positive return on investments (ROIs) and makes for a much more cost-effective investment.Originality/valueThe field of esports sponsorships has received little academic attention and the results are highly significant and relevant for all current and potential esports sponsors looking to increase the effectiveness of their esports sponsorships.

Financial Analysis of Habitat Conservation Banking in California

Habitat conservation banking is a policy instrument for conserving endangered species by providing financial incentives for the landowners in the United States. This policy instrument aims to protect habitat, but little or no thought has been given to its financial performance. A financial analysis of habitat conservation banks (HCB) informs policymakers and conservation biologists of the long-term success of this policy and the future of HCBs. This paper evaluates 26 habitat conservation banks (HCB) in California by calculating their Net Present Values (NPV). We do so by compiling the cost and revenue data for habitat conservation banks. The average annual cost of operating HCBs was $42.78/acre (median: $22.58/acre), and the average credit price or revenue from credit sale was $6014.72/acre (median: $553.65/acre). The average NPV for 26 HCBs was $4205.90/acre at a 4% rate of return, indicating an overall positive return from such an easement instrument. However, only 14 HCBs out of 26 produced a positive return. With the inclusion of land acquisition costs, three of eight HCBs performed financially well. On the brighter side, the number of HCBs has increased with time. But there is not enough evidence to ascertain financial certainty from their revenues. A right selection of space (land acquisition costs can make or break finances for HCB) and species could encourage landowners to establish HCBs. This could build confidence on those who may have been discouraged from lack of knowledge and fear of losing revenue due to regulatory compliance to conserve endangered species habitat in their land. The findings are helpful in identifying lands and prioritizing investments to generate conservation credits.

HERDING BEHAVIOR: MENGEKSPLORASI SISI ANALISIS BROKER SUMMARY

<p><strong><em>Abstract</em></strong><em>: Our research focuses on herding behavior and broker summary analysis in the Covid-19 time frame in Indonesia. Herding behavior in the retail exchange community or the general public is considered detrimental due to the irrationality of analysis and promoting euphoria which results in very large losses. Answering the research gap, we offer a broad exploration concept to avoid and create positive returns by utilizing the herding behavior of the retail market community. We tested using multiple methods to ensure the existence of herding behavior in a regression setting of two and took advantage of positive opportunistic returns for exchange play. The first method shows that the research sample detected herding behavior during March 11, 2020 – March 11, 202 and we ensure the resilience of existence through two models. The second method, to get a positive return, we offer bandarmology analysis adopted from Dow theory for trading in a market maker style. Analyzing the movement and following market makers, we can conclude that it creates positive returns and prevents the stock exchange community from the impact of sustainable auto rejects. This study has limitations, for future research we expect the use of empirical models that are simpler and more efficient in revealing herding behavior. Furthermore, for the exploratory method, further research can be carried out in disclosing bandarmology analysis based on stock categorization (blue chip, second liner, and third liner), time horizon of market makers, and detailed analysis of camouflage behavior of market makers using retail securities.</em></p><p><strong><em>Keywords</em></strong><em>: bandarmology</em><em>;</em><em> brokers summary;</em><em> </em><em>herding behavior; market makers </em></p>

Analyzing the quality factor for Brazil

Investments in Brazil are increasingly allocated to the stock market, at the expense of more conservative investments. Would finding higher-quality assets allow investors to increase their risk-return ratio? We analyze quality with several metrics, including the quality-minus-junk (QMJ) factor for Brazil. We find that quality companies are valued more by investors, with a higher price-to-book ratio. A portfolio of shares of higher quality shows a significant positive return over the period analyzed, adjusted for several risk factors. The sample members classified as quality companies remained within this classification over time.

Five moments of truth: presenting business results to senior executives

Purpose This paper aims to explore the executive request for program results. With major programs in place and other programs planned, executives want to know if they are working. The executive’s perspective focuses on whether these programs impact the organization and do they deliver a positive return on investment (ROI). Design/methodology/approach The paper describes how an executive’s request for ROI will lead human resources professionals to plan an evaluation, collect data, analyze data and present the results to the program sponsors and funders. The success of the results presentation will influence program support and future allocation of funding to HR programs. Findings To be credible, the presentation must include five moments of truth. These five moments of truth require credible data, collected from credible sources, presented in five categories, and a conservative analysis that executives can believe, including proof the program has made a difference. Executives must believe the results are true, or the presentation becomes a waste of time. Originality/value The critical challenge for the HR team is to involve executives in each of the five truths. In the findings, the most successful programs have high executive involvement, beginning with investment alignment and business alignment, and moving through to solution implementation and capability development, and motivation attainment.

Does Friday-Monday Dance with Harmony?

This research is about the weekend effect, a combination of Friday and Monday, and its impact on Monday trading volume. It was found that there was no association between Friday return and Monday return. Still, they occur a combination both Friday and Monday negative return was more than combination both Friday and Monday positive return. There are both combinations (Friday and Monday), and price fluctuation has not affected Monday's volume. There is also no difference in characteristics between groups: Friday and Monday negative return and Friday and Monday positive return. Thus, Friday-Monday dances with harmony; the efficient market occurs. Keywords: Weekend Effect; Trading Volume; Liquidity; Risk-Return; Market Efficient

Vantagens custo-efetivas da utilização de ureteroscópios flexíveis descartáveis em comparação com o uso de ureteroscópios flexíveis reprocessáveis

Objective: To analyze the cost-effectiveness of using disposable flexible ureteroscopes versus using reprocessable flexible ureteroscopes. Methods: Integrative literature review conducted in the SciELO, LILACS and MEDLINE databases, using the descriptors ureteroscopy, flexion resistance, marketing, cost-benefit analysis, and sterilization, whose object deals with the cost-effective advantages of using the flexible ureteroscope disposable. Results: Thirty-five articles were found and four were used in the study. In addition, characteristics of seven models of flexible ureteroscopes commercialized in Brazil, that are currently better known, were presented. The results were based on a joint analysis of the selected articles and characteristics of the flexible models presented, and discussed in two categories: the evolution of flexible ureteroscopes; and marketing mix - flexible single-use ureteroscopes. Conclusion: Despite the scarcity of research that deepens the costs of using a flexible single-use ureteroscope when compared to a reprocessable one, the benefits arising from the innovations added to these devices are notorious, giving a positive return both to the professional who uses it and to the patient, making it necessary to further analyze the possibility of migration from the “culture” of using flexible reprocessable ureteroscopes to disposable ones

Extracting Features of Transient Electric Fields With Fourier And Wavelet Transform–A Case Study Of Lightning Positive Return Stroke

Frequency domain information were extracted from the time domain electric fields pertinent to the lightning positive return strokes applying Fourier transform and Wavelet transform. The electric field radiated by positive ground flashes striking the sea were recorded at 10 ns resolution at a coastal station to minimize the propagation effects. The frequency spectrum of the electric field of positive return strokes were computed applying the Fourier transform technique in the range of 10 kHz to 20 MHz owing to the fact that this range of frequency is of very much interest to the researchers and design engineers. The amplitude of the energy spectral density decreases nearly as ƒ-1 from 10 kHz to about 0.1 MHz and drops nearly as ƒ-2 up to 8 MHz. Applying the wavelet transform technique, the same positive return strokes are found to radiate in the frequency range of 5.5 to 81 kHz with the average spread distribution of 13.6 kHz to about 30 kHz. From frequency spectrum obtained from the Fourier transform it is difficult to identify as which phase of the return stroke radiates in the higher frequency range and that in the lower frequency range, whereas, one can easily identify from the frequency spectrum obtained with the wavelet transform that ramp portion of the positive return stroke radiates in the larger spectral range as compared to that of initial peak of the return stroke. Also, from the spectral density map obtained from wavelet transform one can easily observe the contribution of each phase in a range of frequency, which is not possible from the Fourier transform technique. Clearly, the wavelet transform is much more powerful tool to extract the frequency domain information of a non-stationary signal as compared to that of Fourier transform.
