How maintenance of orientation during locomotion in unfamiliar environments is accomplished was investigated by presenting subjects ( n = 32) a target in different locations in a dark room, having them walk linearly behind a moving light line (1.12 m/sec.), and from a stopping point 12 and 22.6 m away, numerically estimate direction and distance to the target. An equal number of subjects was assigned to each of 2 × 2 treatment levels: the starting point either visible or invisible from the stopping point and the target either visible only from the starting point or throughout each trial. In the conditions with invisible targets there were mainly negative effects of the visible starting point, partially the same as those previously obtained for a concurrent task during locomotion. The results suggested that maintenance of orientation is achieved by recurrent central processing of information, which if postponed leads to impaired performance mainly because forgetting occurs.

The Impact

The impact of globalization on multinational enterprises was examined from the years 1980 to 2020. A scoping literature review was conducted for a total of 141 articles. Qualitative, quantitative, and mixed typologies were categorized and conclusions were drawn regarding the influence and performance (i.e., positive or negative effects) of globalization. Developed countries show more saturated markets than developing countries that favor developing country multinational enterprises to rely heavily on foreign sales for revenue growth. Developed country multinationals are likely to use more advanced factors of production to create revenue, whereas developing country multinationals are more likely to use less advanced forms. A number of common trends and issues showed corporate social responsibility, emerging markets, political issues, and economic matters as key to global market production. Recommendations signal a strong need for more research that addresses contributive effects in the different economies, starting with the emerging to the developed. Limitations of data availability and inconsistency posed a challenge for this review, yet the use of operationalization, techniques, and analyses from the business literature enabled this study to be an excellent starting point for additional work in the field.

Merger Remedies

The article briefly outlines key economic principles that are used for merger appraisal in Europe and the US. We consider three most typical cases: horizontal, vertical and conglomerate mergers. We explain the main positive and negative effects that typically arise in each case. We point that the analysis of structural factors (levels of industry concentration and market shares) and barriers to entry can serve only as a starting point of the merger appraisal process. Other indicators such as closeness of competition, countervailing buyer power and customer switching, counter-reactions of rivals, levels of profitability, cost savings are far more important for the analysis of merger effects on consumers and competition. In addition, we describe general economic principles with regards to merger remedies.

Sense Modalities

The general systems model of central sensory processing used in this study is based on the assumption that central processing is discontinuous and raises this question: Is concurrent processing of different sense modalities serial, parallel, or independent? Since an eye-jump indicates input of visual information, if the auditory system is stimulated by clicks with fixed delays after eye-jumps, intermodality relationships are tested. Reaction times and evoked responses show complex interactions which are interpreted to suggest serial processing analogous to time sharing computers.

The aim of the paper is to assess the effects of the coronavirus pandemic (COVID – 19) on two stock market indices: BET index for Bucharest Stock Exchange and WIG20 index for Warsaw Stock Exchange. The negative effects of the pandemic have had an influence on the performance of the stock markets since its debut. Many companies as well as sectors have ceased their activity during the outbreak, causing devastating financial losses worldwide. By comparing indices evolution during 2020 using the data available on the stock markets’ websites, as well as analyzing in part the companies that make up the indices portfolio, we will try to present the sectors most affected by the pandemic as well as their evolution during the analysis period. The results of this research can be a starting point for future empirical analysis on the long-term effects of the pandemic on stock markets’ performance for Romania and Poland. The results could be a source of information for state institutions, companies, investors, analysts but also representatives of the medical sector (responsible for crisis management) - in order to observe the severity and magnitude of the negative effects of the coronavirus pandemic on the financial markets and also help develop and ensue their long-term sustainable growth.

AbstractThe present study investigated how visuospatial working memory (VSWM) is involved in the construction of a spatial situation model for spatial passages presented auditorily. A simple spatial tapping condition, a complex tapping condition as a target-tracking task, and a control condition, were used to analyze the role of VSWM. To understand how individuals who differ in verbal working memory (VWM) capacity (determined with a listening span test) process spatial text during dual-task performance, individual differences in VWM capacity were analyzed. In two experiments, the participants listened to a spatial text at the same time as performing a spatial concurrent task or no concurrent task. The results of the free recall test in Experiment 1 showed that there were no differences between the tapping conditions in the high VWM capacity group; the low VWM capacity group had a lower performance in both spatial tapping tasks compared to the control condition. The results of the map drawing test in Experiment 2 showed that complex spatial tapping impaired performance in comparison to simple spatial tapping and the control condition in the high VWM capacity group; in the low VWM capacity group, both spatial tapping tasks impaired recall performance. In addition, the participants with high VWM capacity demonstrated better performance. Overall, the results suggest that individuals with high VWM capacity have more resources to process verbal and spatial information than those with low VWM capacity, indicating that VWM capacity is related to the degree of the involvement of VSWM.

BACKGROUND Shift work can be demanding owing to disturbances in the biological and social rhythms. This can cause short-term negative effects in employees, such as increased fatigue and reduced alertness. A potential way to counteract these negative effects is to enhance employees’ recovery from work during working hours. OBJECTIVE The aim of this study is to develop and implement an intervention that focuses on promoting “on-job” recovery of shift workers. METHODS This study is performed in 2 department units with shift workers at a multinational company in the steel industry. For each department, an intervention will be developed and implemented through an iterative process of user-centered design and evaluation. This approach consists of various sessions in which employees and a project group (ie, researchers, line managers, human resource managers, and occupational health experts) provide input on the intervention content and implementation. Intervention effects will be evaluated using pretest and posttest web-based surveys. Digital ecological momentary assessment will be performed to gain insight into the link between the intervention and daily within-person processes. The intervention process and participants’ perception of the interventions will be assessed through a process evaluation. Intervention results will be analyzed by performing mixed model repeated measures analyses and multilevel analyses. RESULTS This study is supported by the Netherlands Organization for Applied Scientific Research Work and Health Research Program, which is funded by the Ministry of Economic Affairs and supported by the Dutch Ministry of Social Affairs and Employment, program number 19.204.1-3. This study was approved by the institutional review board on February 7, 2019. From June to August 2019, baseline data were collected, and from November to December 2019, the first follow-up data were collected. The second follow-up data collection and data analysis are planned for the first two quarters of 2020. Dissemination of the results is planned for the last two quarters of 2020. CONCLUSIONS A strength of this study design is the participatory action approach to enhance the stakeholder commitments, intervention adherence, and compliance. Moreover, since the target group will be participating in the development and implementation of the intervention, the proposed impact will be high. In addition, the short-term as well as the long-term effects will be evaluated. Finally, this study uses a unique combination of quantitative and qualitative evaluation methods. A limitation of this study is that it is impossible to randomly assign participants to an intervention or control group. Furthermore, the follow-up period (6 months) might be too short to establish health-related effects. Lastly, the results of this study might be specific to the department, organization, or sector, which limits the generalizability of the findings. However, as workplace intervention research for shift workers is scarce, this study might serve as a starting point for future research on shift work interventions.
