In recent years, a debate on the technological sources of the next long wave of growth has emerged. In this context, some authors consider that health-related industries will be more likely to generate new technological systems than defense-related industries, which have entered a stage of technological maturity (Ruttan 2006; Steinbock 2014; among others). Based on evolutionary works, in this paper we state that technological systems are characterized by a high degree of technological relatedness, which is positively associated with the possibility of a system to generate variety through the recombination of knowledge from a common base. Following this statement, this work aims to analyze technological relatedness between defense (and health) technological system(s) and other groups of products to compare their variety patterns. Based on international trade data (a panel for 60 countries and 17 years), and different measures of proximity and relatedness (e.g. sectoral competitiveness of countries), we compare defense and health technological systems regarding their potential of generating related variety through two main methods network analysis and econometrical analysis. The main results support Ruttan's hypothesis. The network analysis shows the potential for both systems to generate related variety, but higher centrality indicators for health products. In line with that, competitiveness in health products presents a stronger correlation with competitiveness in other groups of products, both related and high and medium technology. This suggests that an improvement in countries' competitiveness in health sectors can generate spillovers on other related sectors, which can strengthen structural competitiveness and sustain long-term growth.This note comments on the questionable approach and claims made in "Study of mixed-mode oscillations in a nonlinear cardiovascular system" [Nonlinear Dyn, doi 10.1007/s11071-020-05612-8]. Although the author of the above paper attempts to discuss a nonlinear cardiovascular system and its dynamics, the conductance model used, is that of the well-known Cassie-Mayr model of electric arcs, known in the literature since the 1940s. No reference to that well-known model is made however. Moreover, the claim that the conductance model is taken "from the data of a large patient population" is baseless and has no grounds in reality. Thus, an extreme caution is advised, when analyzing the time responses and properties of the nonlinear model in the commented paper. It is questionable that they represent quantities of a human cardiovascular system.Stalking involves repeated unwanted communication, harassment, and intrusive behaviour. This brief report draws on a service evaluation undertaken immediately prior to and during the 2020 COVID-19 crisis. The pandemic creates a paradox when considering safety in the home, but it is important to recognise the dangers this presents to many victims of stalking. click here The information presented in this report is based on existing literature and early evidence from semi-structured interviews and discussions with 15 victims and six practitioners. Whilst lockdown measures might appear to be a time when victims are less accessible to their stalkers, early evidence from this study suggests that their vulnerability is increased. Technology has helped to facilitate stalking behaviours by providing stalkers with new approaches to control, humiliate, threaten and isolate their victims. Some lockdown restrictions have provided increased opportunities for stalkers to monitor their victims and the professional uncertainty and recognition around stalking has continued, coupled with delays in the criminal justice system. The COVID-19 crisis has reversed gains made by stalking victims and has imprisoned some victims in their homes making their whereabouts easier to monitor. Stalking behaviour has not ceased as a result of the COVID-19 restrictions and the risk of harm to victims remains significant. Effective practice, policy and legal responses are required for both the victims and perpetrators of stalking during the pandemic and afterwards.Maize (Zea mays L.) is the essential staple in sub-Saharan Africa (SSA) and Tanzania in particular; the crop accounts for over 30% of the food production, 20% of the agricultural gross domestic product (GDP) and over 75% of the cereal consumption. Maize is grown under a higher risk of failure due to the over-dependence rain-fed farming system resulting in low income and food insecurity among maize-based farmers. However, many practices, including conservation agriculture, soil and water conservation, resilient crop varieties, and soil fertility management, are suggested to increase cereal productivity in Tanzania. Improving planting density, and the use of fertilizers are the immediate options recommended by Tanzania's government. In this paper, we evaluate the economic feasibility of the improved planting density (optimized plant population) and N-fertilizer crop management practices on maize net returns in semi-arid and sub-humid agro-ecological zones in the Wami River sub-Basin, Tanzania. We introduce a birid and 14.6% to 30.2% probability of negative net returns for sub-humid zones. The results suggest that the application of fertilizer practices reduces the risks associated with the mean returns, but increasing the plant population has a high probability of economic failure, particularly in the sub-humid zone. Maize sub-sector in Tanzania is projected to continue experiencing a significant decrease in yields and net returns, but there is a high chance that it will be better-off if proper alternatives are employed. Similar studies are needed to explore the potential of interventions highlighted in the ACRP for better decision-making.Although the importance of workplace fun in hospitality organizations has been emphasized by scholars, discussion of the mechanism of a workplace fun climate in collectivistic cultural contexts is still rare in current literature. Therefore, based on a collectivistic perspective, this study aims to examine the effects of a three-component fun climate at work (socializing with coworkers, celebrating at work, and global fun at work) on employee deep acting and work-family conflict. A total of 389 usable survey responses were collected from full-time hotel employees in China. The results of this study reveal that socializing with coworkers and celebrating at work enhance global fun at work. Moreover, global fun at work significantly reduces employees' work-family conflict and strengthens their deep acting at work. Findings of this study not only contribute to knowledge of understanding workplace fun climate in hospitality literature but also offer valuable practical implications to the hospitality industry.
