The nemoral forests of the montane level are especially interesting, because they are on the edge of their distribution. We want to see the influence of some environmental conditions (temperature and rainfall) on the litterfall and growth, in three kinds of these forests. The Montseny massif in the NE part of Iberian Peninsula, with a maximum altitude of 1.706 m, has a strong gradient of climate and vegetation, from the lowlands to the top of the mountains. We analyze three forests in the Montseny massif, two of them are composed by deciduous species not very extensive in the region (beech and sessile oak) and the other is a Mediterranean species, the mountain holm oak. We recollect data since 2007, monthly litterfall was measured and radial growth, and correlated with the climate of the study area. Our results shows that Fagus sylvatica recorded the biggest drop in annual litterfall (6.3 Mg / ha), followed by Q. ilex (5.3 Mg / ha) and Q. petraea (4.6 Mg / ha) all recorded values ​​are similar to those observed in other forests and mountains of the same state of maturity equivalent. The start of the growth took place in the spring and Quercus spp. occurred more gradually than in F. sylvatica. We found that the accumulated rainfall in late spring has had a positive effect specially on the growth of Quercus species while the effect of summer temperature has been especially prominent in beech. Mediterranean species show larger fluctuations growth than Central European ones in response to lower water availability.

The analysis of a data set of observation for Vietnamese banks in period from 2011 - 2015 shows how Capital Adequacy Ratio (CAR) is influenced by selected factors: asset of the bank SIZE, loans in total asset LOA, leverage LEV, net interest margin NIM, loans lost reserve LLR, Cash and Precious Metals in total asset LIQ. Results indicate based on data that NIM, LIQ have significant effect on CAR. On the other hand, SIZE and LEV do not appear to have significant effect on CAR. Variables NIM, LIQ have positive effect on CAR, while variables LLR and LOA are negatively related with CAR.

This study examined how weekly, externally set deadlines affected the completion of adaptive learning assignments and student outcomes in an introductory macroeconomics course. We imposed different deadline schemes for the same adaptive learning assignments in two sections of the course. One section was given flexible deadlines and the other section was given rigid weekly deadlines. We found that weekly deadlines did not affect assignment completions or total points earned on unit exams. We investigated how the adaptive learning assignments affected student retention of material. A measure of staying on pace in the course provided a positive effect on the comprehensive final exam for students with weekly deadlines. The weekly deadlines may not have influenced assignment completions but consistent engagement with the flow of topics through the course increased student knowledge retention. Regardless of deadline type, completions of adaptive learning assignments positively affected outcomes on the unit exams and final exam. JEL Classifications: A20, A22

To practice strength and balance activities are shown as useful tools to fall prevention by diverse metanalysis. On the other side, aquatic environment offers interesting properties for a therapeutic reeducation, being the Ai Chi one of its applications. Aim: To evaluate the repercussion of an Ai Chi programme on aged people’s balance. Method: A randomized controlled trial was developed comparing two groups formed by aged people with risk of fall according to the Timed Up & Go test. Intervention Group (IG) followed twelve Ai Chi sessions combined with their thermal programme; and Control Group (CG) just followed the thermal programme. Both groups spent two weeks in the Balneario of Archena (Murcia, Spain). Results: Both groups improve their balance; however, only the IG reached the non-risk of fall from the Timed Up & Go test. Conclusions: The combination of Ai Chi sessions and a thermal programme had a positive effect on aged people’s balance, showing a therapeutic and clinical relevance.

Over Time

Development of calves depends on prenatal and postnatal conditions. Primiparous cows were still maturing during pregnancy, which can lead to negative intrauterine conditions and affect the calf’s metabolism. It is hypothesized that weaning calves at higher maturity has positive effects due to reduced metabolic stress. We aimed to evaluate effects of mothers’ parity and calves’ weaning age on growth performance and blood metabolites. Fifty-nine female Holstein calves (38.8 ± 5.3 kg birth weight, about 8 days old) were used in a 2 × 2 factorial experiment with factors weaning age (7 vs. 17 weeks) and parity of mother (primiparous vs. multiparous cows). Calves were randomly assigned one of these four groups. Live weight, live weight gain and morphometry increased over time and were greater in calves weaned later. Metabolic indicators except total protein were interactively affected by time and weaning age. Leptin remained low in early-weaned calves born to primiparous cows, while it increased in the other groups. The results suggest that weaning more mature calves has a positive effect on body growth, and calves born to primiparous cows particularly benefit from this weaning regimen. It also enables a smooth transition from liquid to solid feed, which might reduce the associated stress of weaning.

Water Scarce

More than one-quarter of the world’s population lives in water-scarce areas, while most countries share at least one transboundary river. If water scarcity is this prevalent, should we expect riparian countries to fight over the water allocation of shared rivers? To answer this question, I develop a modified one-shot three-stage river-sharing game where countries can resort to force to solve their water allocation problem. Using backward induction, I solve for the probability of the downstream country initiating conflict against the upstream country and the likelihood of the latter responding with force to the former’s hostile actions. I test the model empirically using a set of all upstream–downstream riparian dyads with available data from AQUASTAT and the Correlates of War Project for the years 1960–2010. The main contribution of this paper is that it demonstrates how upstream and downstream riparian countries differ in their decision to use force against the other country when experiencing water scarcity. I find that water scarcity increases the likelihood of the downstream country initiating the conflict, but it has no effect on the upstream country’s likelihood of responding with force. If history is a predictor of the future, then the results imply that as more riparian countries become water-scarce, militarized conflicts between upstream and downstream countries are likely to increase, especially if there is heterogeneity in water availability between the riparian dyad.

Minor Irrigation

The study examined the impact of minor irrigation on agricultural production and evaluated the gap between IPC and IPU in the Keonjhar district of Odisha. For this rationale, data were collected from 210 farm households through the primary survey. In support of the analysis, the Cobb Douglas model and factor analysis were used. The results revealed that the input use efficiency had a positive and significant impact on paddy production the most in all the MIPs regions compared to the other crops. However, the study indicated that insufficient water availability was the major cause behind the gap between irrigation potential created and utilised. Thus, minor irrigation played a crucial role in enhancing agricultural production in hilly regions. With the enthusiastic participation of planners, effective working of Pani Panchayats, canals, and upstream control, NGOs' involvement can achieve selfsufficiency in agricultural production by encouraging minor irrigation projects in the hilly province.

Tamarack (Larix laricina [DuRoi] K. Koch) was severely defoliated by the larch casebearer (Coleophora laricella) in most areas of Quebec during 1979 and 1980. Increment core samples were taken in late September 1982 from 20 tamaracks in each of two stands to determine the effect of defoliation on radial growth. In one stand, the trees were 80% defoliated in 1980 and during this year radial growth was reduced by 52%. Growth returned to predefoliation level the following year when the trees were not defoliated. In the other stand, trees were 60% defoliated in 1979 and 70% in 1980. During these years, radial growth was reduced by 48 and 70% respectively. Growth in this stand had not fully returned to predefoliation level two years after the collapse of the infestation. In both stands, variations in defoliation among trees did not exceed 10% of the average. Key Words: Coleophora laricella, larch casebearer, tamarack, larch, defoliation.

Materialism and sich are the driving spirit of the community in achieving economic and financial security that saves a holistic and socially just welfare. This can be seen from the lives of people in materialistic developed countries, where the level of social stress is higher, economic inequality widens, horizontal conflict is rife. This research uses Pierre Felix Bourdieu's social theory in seeing people trust the expenditure of material with other values, such as spiritual and cultural values ​​that are no less urgent as elements of social welfare development. This study found that materialism on the one hand has a positive effect, where people are encouraged to use material standards in measuring the level of welfare they expect. On the other hand, materialism closes the presence of values ​​such as spirituality, local wisdom and agriculture in completing more holistic welfare standards.

The article follows the narrative trend initiated by the social media posts and fake news during the first months of the corona quarantine, which claims that the decrease of contamination due to the quarantine has a positive effect on the environment and nature recovery. The author describes the context of the topic and follows the changes in the rhetoric through different genres, discussing the ways in which a picture can tell a truthful story. What is the relation between the context, truth, and rhetoric? This material spread globally, yet it was also readily “translated” into the Estonian context, and – what is very characteristic of the entire pandemic material – when approaching this material, truthful and fabricated texts, photos, and videos were combined. From the folkloristic point of view, these rumours in the form of fake news, first presented in the function of a tall tale and further following the sliding truth scale of legends, constitute a part of coping strategies, so-called crisis humour, yet, on the other hand, also a belief story presenting positive imagery, which surrounds the mainly apocalyptically perceived pandemic period and interprets the human existence on a wider scale. Even if these fake news and memes have no truth value, they communicate an idea – nature recovers – and definitely offer hope and a feeling of well-being.
