French broom (Genista monspessulana) (Fabaceae) is a perennial species native to the Mediterranean basin. Introduced in the 19th century as an ornamental plant, it is currently invasive in California and Australia. The current research is focused on biocontrol with the use of the phytophagous weevil Lepidapion argentatum (Brentidae). Its capacity to develop both in the stem galls and pods of French broom makes it a promising candidate. The impact on the reproduction of French broom was studied in Southern France and revealed that it could effectively reduce the number of viable seeds by 18.8%, but also increased the number of aborted seeds by 10% within the attacked pods. To evaluate the specificity of L. argentatum, choice and no-choice tests were performed in 2012 and 2015 on a total of 36 non-target closely related species. Results revealed the presence of galls and larvae in the stems of seven species, including two endemic Californian lupines; i.e., Lupinus arboreus blue and Lupinus chamissonis. In the future, new tests will be conducted to determine if L. argentatum is able to complete its entire development lifecycle on the non-target species where galls have previously been observed.

The history of Islam in part of what is known today as Nigeria datesto about the loth Century. Christianity dates to the late 18th Century. Bythe middle of the 19th Century, when Nigerian newspapers began to appearon the streets of Nigeria, both religions had won so many followers and extendedto so many places in Nigeria that very few areas were untouched bytheir influence. The impact of both religions on their adherents not only determinedtheir spiritual life, but influenced their social and political lives aswell. It therefore became inevitable that both religions receive coverage frommost of the newspapers of the time. How the newspapers as media of informationand communication reported issues about the two religions is thetheme of this paper.Rationale for the StudyThe purpose of this study is to highlight the context in which such earlynewspapers operated and the factors that dictated their performance. Thisis because it is assumed that when a society faces external threat to its territory,culture, and independence, all hands (the press inclusive) ought tobe on deck to resist the threat with all might. Were newspapers used as verbalartillery and how did they present each religion? It is also assumed thatin a multireligious society a true press should be objective and serve as avanguard in the promotion of the interest of the people in general and notcreate or foster an atmosphere of religious conflict. The study also aims atfinding out whether the papers promoted intellectual honesty and fosteredthe spirit of unity particularly when the society was faced with the encroachmentof the British who posed a threat to their freedom, culture, economy ...

The present essay presents the content of the landmarks that punctuate the long dialogue between verbal language and musical language during the 19th Century, by means of examples taken from the critical and theoretical writings of Hector Berlioz, Robert Schumann and Richard Wagner. In the search for the dramatic essence of music, such dialogue took different forms: the possibility of verbal language being translated by musical language, the pre-existence of a musical-poetic idea in any musical composition, eventually contributing to the appearance of program music, and finally, the principles presiding over Wagner’s Gesamtkunstwerk. Special emphasis is given to Richard Wagner’s Parisian article De l'Ouverture (1841), as well as to the impact on Soren Kierkegaard.

In the colonial period imperialism advanced in uneven ways across time and space globally. European exploration in the late 15th century first brought destructive, exploitative, and deadly changes to what became known as the Americas. The subjugation and elimination of Indigenous groups, which commenced during this period, created the conditions for accumulation by dispossession, enslavement (of both Indigenous groups and people stolen from Africa), plantation-style production systems, and the extraction of resources—the legacies of which still mark political, social, economic, and environmental landscapes today. Following rebellion and successful de jure (legal) independence from Europe in the late 1700s and early 1800s (starting with the radical uprising of enslaved peoples in Haiti), Western powers turned to new regions to regain such systems of control and resource extraction. In 1848, the Berlin Conference was held— also called the “Scramble for Africa,” where European powers divided the continent and created new sites of extraction. Such patterns followed in South and Southeast Asia as well as North Africa and Central Asia in the latter parts of the 19th century. As a result of these violent campaigns, there are very few places on the globe that did not sustain, at some point, a form of colonial-imperial relation. Independence movements were ongoing and by the end of the 20th century, de jure colonial control had all but disappeared. Decolonization had occurred and the global periphery entered the period of being postcolonial. Former British colonies were assembled into the Commonwealth, which changed relations from direct control and subjugation to allegiance to the Queen and for some, drastic changes in economic relations, (this had the effect of marginalizing Indigenous struggles in many of these places). Notwithstanding the legal separation of the colonies from imperial powers, de facto (in effect) colonial arrangements lingered and remain today, giving rise to a series of critiques and new ways of thinking about imperialism and the impact of colonialism, such as the theory of postcolonialism.

An overview of the areas of sibling research that laid the foundation for the modern understanding of sibling issues is presented. Attention is focused on the importance of sibling relationships for personal development, socialization and adaptation, and on the existing shortage of relevant work at the same time. The main stages of the development of sibling theory in their continuity are considered, starting from the first studies devoted to the search for a connection between the order of birth and achievements and dated to the end of the 19th century, to the term “individual environment” developed by the genetics of behavior in the second half of the 20th century. It emphasizes the role of A. Adler, who has made sibling a central feature of family life and personal development and has long determined the future direction of empirical family research. It shows a gradual shift in the interest of researchers from studying the influence of birth order, gender, and age intervals between siblings on personal characteristics. In this connection, an analysis of the nature of sibling relations on the basis of reciprocity and complementarity, undertaken by Dunn, is given. Early works on the jealousy and rivalry of children in the family, the study of the impact of parental differential treatment on them, as well as the influence of child characteristics on siblings in families with sick children are considered.

Abstract: This research discusses the process of forming and developing of Pondol village in Manado as a location for exile along with the Dutch colonial government policy that placed exiles who came from several sultanates in Java in the Manado Residency during the 19th century. The discussion includes, first, the background of the exile of the Javanese aristocrats in Manado. Second, the process of establishing Pondol as a location for exile and its development during the XIX century, and third, the adaptations made by the exiles to adjust to their exile and the impact of their arrival on the Manado-Minahasa community. The historical method is used in this research, using colonial archives from the XIX century which are stored in the National Archives of the Republic of Indonesia, and local sources, especially manuscripts stored by their descendants in Manado and Java. The findings in this study are; Kampung Pondol was formed due to the isolation of Kanjeng Ratu Sekar Kedaton and Pangeran Suryeng Ingalaga and some of his followers originated from political intrigue that occurred in the Sultanate of Yogyakarta. Second, the reason why Kampung Pondol was chosen as the new location for exile by the Dutch colonial government for Javanese royal officials was different from the exile of other figures in Tondano and Tomohon. Third, the form of adaptation carried out by the exiles in Kampung Pondol Manado was marriage with women from Manado and relationships with Dutch people who lived around them.Keywords : Exile, Javanese Noble, Pondol Village, Adaptation. Abstrak: Penelitian ini membahas tentang proses terbentuk dan perkembangan kampung Pondol di Manado sebagai lokasi pengasingan seiring dengan kebijakan pemerintah kolonial Belanda yang menempatkan para eksil yang berasal dari beberapa kesultanan di Jawa di Karesidenan Manado pada sepanjang abad 19.  Pembahasannya meliputi; Pertama, Latar belakang pengasingan para bangsawan Jawa di Manado. Kedua, proses terbentuknya Pondol sebagai lokasi pengasingan dan perkembangannya selama abad XIX, dan Ketiga, adaptasi yang dilakukan para eksil untuk menyesuaikan diri di pengasingan serta dampak kedatangan mereka pada masyarakat Manado-Minahasa. Metode sejarah dipergunakan dalam penelitian ini, dengan mempergunakan sumber Arsip Kolonial kurun waktu abad ke XIX yang tersimpan di Arsip Nasional Republik Indonesia,  dan sumber lokal terutama manuskrip yang tersimpan oleh keturunannya di Manado dan Jawa. Temuan dalam penelitian ini adalah; Kampung Pondol terbentuk karena Pengasingan Kanjeng Ratu Sekar Kedaton dan Pangeran Suryeng ingalaga dan beberapa pengikutnya berawal dari intrik politik yang terjadi di Kesultanan Yogyakarta. Kedua, alasan Kampung Pondol dipilih sebagai lokasi baru pengasingan Pemerintah Kolonial Belanda bagi pembesar kerajaan Jawa yang berbeda lokasi dengan pengasingan tokoh-tokoh lainnya di Tondano dan Tomohon. Ketiga, bentuk adaptasi yang dilakukan oleh para eksil di Kampung Pondol Manado dilakukan pernikahan dengan wanita dari Manado dan relasi dengan orang-orang Belanda yang tinggal disekeliling mereka.Kata Kunci : Eksil, Bangsawan Jawa, Kampung Pondol, Adaptasi.

BACKGROUND: E-learning techniques are spreading at great speed in medicine, raising concerns about the impact of adopting them. Websites especially designed to host courses are becoming more common. There is a lack of evidence that these systems could enhance student knowledge acquisition. GOAL: To evaluate the impact of using dedicated-website tools over cognition of medical students exposed to a first-aid course. METHODS: Prospective study of 184 medical students exposed to a twenty-hour first-aid course. We generated a dedicated-website with several sections (lectures, additional reading material, video and multiple choice exercises). We constructed variables expressing the student's access to each section. The evaluation was composed of fifty multiple-choice tests, based on clinical problems. We used multiple linear regression to adjust for potential confounders. RESULTS: There was no association of website intensity of exposure and the outcome - beta-coeficient 0.27 (95%CI - 0.454 - 1.004). These findings were not altered after adjustment for potential confounders - 0.165 (95%CI -0.628 - 0.960). CONCLUSION: A dedicated website with passive and active capabilities for aiding in person learning had not shown association with a better outcome.

Since the beginning of the 19th century, we have assisted major proliferation of the oil and gas industry. This phenomenon of exponential growth is due to the fact that oil companies hold the world’s oil monopoly on the extraction, processing and commercialization. Therefore, as being one of the most influential sectors in the world, is crucial to strictly regulate how oil and gas contracts concerns the potential environmental and social impacts arising from the conduct of petroleum operations and how such behavior affects the human rights. As a matter of fact, the social issues field is an emerging area, and despite such importance, oil contracts do not often deal with them in great detail, corresponding to an actual emptiness of the human rights provisions. In terms of responsibly, oil companies, have an inalienable obligation to ensure that their actions do not violate human rights or contribute for their violation. This study aims to trace a detailed analysis of the impact of the oil and gas agreements in human rights. In order to fully comprehend the deep effects of this industry, we will examine, in detail, numerous of published oil and gas agreements, as well as, decode which are the real standards and practices accepted by this industry. We will use a deductive and speculative reasoning. We will try to demonstrate how incipient and short protection is given to human rights and what responsible conducts must urgently be developed.

This paper investigates the mapping of the impact of natural hazards as included in several databases reviewed or created by the author. These are: - The database of the contribution of the session series “Natural hazards’ impact on urban areas and infrastructure”, convened and co-convened by the first author over 15 years at the European Geosciences General Assembly. - A database created from reviews of students supervised by the authors in frame of the course “Protection of settlements against risks” at the home university. - A collection of historical photographs from the 19th century on different natural and man-made hazards from the Canadian Centre for Architecture, the archive review of which has been performed by the first author and which will be subject of a book to be published about the time of the conference. -Two reviewed collections, one from the exhibition and book on “Images of disasters” (German research) and one on the book “Illustrated history of natural disasters” which include major disasters from the beginning of the mankind. In frame of the paper maps of the spread of data will be presented, created using both arcGIS online and GoogleMaps (see https://www.google.com/maps/d/edit?mid=zpbbz3WgVMBs.k-3vhGj- -l1M&usp=sharing), comparing the source and the type of hazard, to see eventual overlappings between the databases.
