Long-term monitoring of the Masked Owl Tyto novaehollandiae in a semi-urban landscape before, during and after large-scale habitat removal identified a positive response in breeding activity in the short-term and a change in prey selectivity. Over the longer term, the loss in habitat had a negative impact on site fidelity. A pair of Masked Owls exhibited high fidelity to a particular breeding territory before and during the removal of large areas of habitat within this territory. Breeding success occurred over two consecutive seasons during the removal of known habitat and other disturbance events at which time the pair and their offspring were observed to exploit disturbed habitat and newly created forest edges in search of prey. Breeding activity was supported by an increased dietary focus on introduced rodents and other mammals displaced during habitat clearing. Fidelity to the breeding territory became more irregular post-disturbance and after two years the territory appeared to be abandoned. This response may suggest that the cumulative loss of habitat for established pairs as a result of urban expansion is likely to adversely affect reproductive success and site fidelity in the longer term.

Abstract Background While a strong negative impact of unemployment on health has been established, the present research examined the lesser studied interplay of gender, social context and job loss on health trajectories. Methods Data from the German Socio-Economic Panel was used, which provided a representative sample of 6838 participants. Using latent growth modelling the effects of gender, social context (East vs. West Germans), unemployment (none, short-term or long-term), and their interactions were examined on health (single item measures of self-rated health and life satisfaction respectively). Results Social context in general significantly predicted the trajectories of self-rated health and life satisfaction. Most notably, data analysis revealed that West German women reported significantly lower baseline values of self-rated health following unemployment and did not recover to the levels of their East German counterparts. Only long-term, not short-term unemployment was related to lower baseline values of self-rated health, whereas, in relation to baseline values of life satisfaction, both types of unemployment had a similar negative effect. Conclusions In an economic crisis, individuals who already carry a higher burden, and not only those most directly affected economically, may show the greatest health effects.

The paper proposes an effective continuous gesture recognition method, which includes two modules: segmentation and recognition. In the segmentation module, the video frames are divided into gesture frames and transitional frames by using the information of hand motion and appearance, and continuous gesture sequences are segmented into isolated sequences. In the recognition module, our method exploits the spatiotemporal information embedded in RGB and depth sequences. For the RGB modality, our method adopts Convolutional Long Short-Term Memory Networks to learn long-term spatiotemporal features from short-term spatiotemporal features obtained from a 3D convolutional neural network. For the depth modality, our method converts a sequence into Dynamic Images and Motion Dynamic Images through weighted rank pooling and feed them into Convolutional Neural Networks, respectively. Our method has been evaluated on both ChaLearn LAP Large-scale Continuous Gesture Dataset and Montalbano Gesture Dataset and achieved state-of-the-art performance.

The large scale of the contamination by the former carbo-chemical industry in Germany requires new and often interdisciplinary approaches for performing an economically sustainable remediation. For example, a highly toxic and dark-colored phenolic wastewater from a lignite pyrolysis factory was filled into a former open-cast pit, forming a large wastewater disposal pond. This caused an extensive environmental pollution, calling for an ecologically and economically acceptable strategy for remediation. Laboratory-scale investigations and pilot-scale tests were carried out. The result was the development of a strategy for an implementation of full-scale enhanced in situ natural attenuation on the basis of separate habitats in a meromictic pond. Long-term monitoring of the chemical and biological dynamics of the pond demonstrates the metamorphosis of a former highly polluted industrial waste deposition into a nature-integrated ecosystem with reduced danger for the environment, and confirmed the strategy for the chosen remediation management.

The study aims to analyzing the reciprocal relationship between the nominal exchange rate of the Turkish lira versus the U.S. dollar and the stock prices of the companies listed on the Istanbul Stock Exchange (ISE) expressed in the general market index for the period from 2005 to 2020 with 192 monthly observations, based on the traditional theory and the theory of portfolio balance model in theoretical interpretation for that relationship, aiming to identify the effect of the exchange rate on stock prices, as well as to analyze the causal relationship between those variables and to identify which of them is the cause or which is the result, using the Autoregressive Distributed Lag (ARDL) model. The research found that the exchange rate has a positive effect on stock prices in the long term, despite the emergence of the negative impact in the short term, but the long-term relationship has corrected the course of the short-term relationship with a time period not exceeding one month, in addition to proving that this relationship takes one direction. From the exchange rate towards stock prices, that is, the exchange rate is the reason and stock prices are the result, therefore the results of this research helps investors to predict future trends of stock prices depending on the exchange rate changes, and it also enables the companies, especially those with foreign transactions, to manage price risks the exchange rate in order to avoid its negative impact on its share price, as it represents an obstacle to achieving its main goal of maximizing the share price

Abstract The widely recognized need for large-scale transition from fossil to renewable energy sources has led to renewed effort to obtain metals needed for battery-based electric transportation and other functions. A potential source of some of these metals is the deposits of polymetallic nodules on the deep seafloor. If mining of these deposits proceeds in the coming decade, the enterprise creates an opportunity for extensive, long-term oceanographic research in the mining locations. The need to monitor environmental effects of mining activity can best be met with a near-continuous presence of a research platform in the vicinity. The platform could be a ship or potentially a semi-submersible platform like those used in the offshore oil industry. Such a facility might be supported by a consortium of mining companies and also provide opportunities for academic research in ocean and climate science.

Bullying is deliberate aggressive action, using an imbalance of strength physically or mentally by hurting physical, verbal, or emotional / psychological forms repeatedly. In the last decade, cases of bullying in Indonesia continue to increase and if not handled properly will increasingly have a negative impact on the development of the children of the nation's next generation. Bullying does not only affect children who are bullied but can also affect children who bully, children who witness bullying. Some of the effects of bullying include anxiety, depression, and low self-esteem. The purpose of community engagement is to socialize the impact of bullying and how to increase self-esteem to adolescents. Through psychoeducation programs in adolescents such as schools and teenagers religious communities in the Cikarang - Bekasi region, young people gain an in-depth understanding of bullying, its effects and how to increase their confidence. Through this psychoeducation, teenagers understand the understanding, types and effects of bullying both short term and long term so they promise to resist bullying starting from themselves. Teenagers learn that humans are social beings who need each other. They learn about the meaning of diversity and bhineka tunggal ika and try to implement it in their next lives by respecting the differences in their environment. These teenagers learn to respect themselves more, see the positive things that God has given them. They try to always believe in themselves that they are perfect and valuable beings in God's eyes so that even though the environment around them may not appreciate, they can still see positive things in themselvesABSTRAK:Bullying adalah tindakan agresif yang disengaja, menggunakan ketidakseimbangan kekuatan secara fisik atau mental dengan cara menyakiti bentuk fisik, verbal, atau emosional/ psikologis secara berulang – ulang. Dalam satu decade terakhir, kasus bullying di Indonesia terus meningkat dan bila tidak ditangani dengan baik akan semakin berdampak negative bagi perkembangan anak – anak generasi penerus bangsa. Tindakan bullying tidak hanya berdampak pada anak yang di-bully tetapi juga dapat berdampak pada anak yang mem-bully, anak yang menyaksikan bullying. Beberapa dampak bullying diantaranya kecemasan, depresi, serta rendahnya harga diri (self-esteem). Tujuan dari pengabdian kepada masyarakat ini adalah untuk mensosialisasikan dampak bullying serta cara meningkatkan self-esteem kepada para remaja. Melalui program psikoedukasi di lingkungan remaja seperti sekolah maupun komunitas keagamaan remaja wilayah Cikarang – Bekasi, para remaja mendapatkan pemahaman mendalam mengenai bullying, dampaknya serta bagaimana cara meningkatkan kepercayaan diri mereka. Melalui psikoedukasi ini, para remaja memahami pengertian, jenis serta dampak bullying baik jangka pendek maupun jangka panjang sehingga mereka berjanji untuk bersikap menolak bullying mulai dari diri mereka sendiri. Para remaja belajar bahwa manusia adalah mahluk social yang saling membutuhkan. Mereka belajar tentang makna keberagaman dan Bhineka Tunggal Ika serta berusaha mengimplementasikannya dalam kehidupan mereka selanjutnya dengan cara menghargai perbedaan yang ada di lingkungannya. Remaja ini belajar untuk lebih menghargai diri mereka, melihat hal positif yang telah diberikan Tuhan kepada mereka. Mereka mencoba untuk selalu menanamkan dalam diri bahwa mereka adalah mahluk yang sempurna dan berharga di mata Tuhan sehingga walaupun lingkungan di sekitar mereka mungkin tidak menghargai, mereka tetap dapat melihat hal positif dalam diri mereka.

ABSTRACTBackgroundVarious surveys have documented a negative impact of the COVID-19 pandemic on the population’s mental health. There is widespread concern about a surge of suicides, but evidence supporting a link between global pandemics and suicide is very limited. Using historical data from the three major influenza pandemics of the 20th century, and recently released data from the first half of 2020, we aimed to investigate whether an association exists between influenza deaths and suicide deaths.MethodsAnnual data on influenza death rates and suicide rates were extracted from the Statistical Yearbook of Sweden from 1910-1978, covering the three 20th century pandemics, and from Statistics Sweden for the period from January to June of each year during 2000-2020. COVID-19 death data were available for the first half of 2020. We implemented non-linear autoregressive distributed lag (NARDL) models to explore if there is a short-term and/or long-term effect of increases and decreases in influenza death rates on suicide rates during 1910-1978. Analyses were done separately for men and women. Descriptive analyses were used for the available 2020 data.FindingsBetween 1910-1978, there was no evidence of either short-term or long-term significant associations between influenza death rates and changes in suicides. The same pattern emerged in separate analyses for men and women. Suicide rates in January-June 2020 revealed a slight decrease compared to the corresponding rates in January-June 2019 (relative decrease by −1.2% among men and −12.8% among women).InterpretationWe found no evidence of short or long-term association between influenza death rates and suicide death rates across three 20th century pandemics or during the first six months of 2020 (when the first wave of COVID-19 occurred). Concerns about a substantial increase of suicides may be exaggerated. The media should be cautious when reporting news about suicides during the current pandemic.
