  • ANNUAL REPORT Preface
    2017ANNUAL REPORT Preface Every passing year becomes our reflection to reach our vision for every child life in all its fullness. We always feel grateful when we listen to every story and see the changes in the children and communities whom we have supported through 62 child-focused programs. The involvement of many parties in the effort to promote the well-being of children becomes an encouragement for the sustainability of the assisting programs in the community which is run by Wahana Visi Indonesia (WVI). The alignment of our programs in the field with the programs that are run by the central and local government become our focus for the sustainability of our program in the long run. In 2017, one of WVI's agendas is to give priority to child protection, without setting aside programs in other sectors such as education, health and the family economy. WVI's commitment to protect children is portrayed through the launch of Ending Violence against Children (Penghapusan Kekerasan Terhadap Anak / PKTA) campaign which will run over the next 5 years, together with 20 other non-government organizations belonging to the PKTA Alliance. Thank you for every effort and collaboration that has been done throughout this year. We believe that every single thing that we have done for the children becomes hope to promote the well-being of the children. Let's go hand in hand for the Indonesian children.

  • East Flores Witness Something Truly Majestic®
    East Flores Witness Something Truly Majestic® thth 8SAFARI Page 1 The Mystical Archipelago of Lembata & Alor Venture to the isolated archipelago where its myth, culture and wilderness are lost in time. Legend has it that after a particularly long drought in the Dolabang Village at Pura Island, a local man, Olangki, made a journey to Reta Village to borrow rice. The following year, while on way to return the borrowed rice, he saw a pig on the top of Maru Mountain. He tried, but failed, to slay the pig. In his despair, he asked for help from Dewa “God” to give him water and in return he would give away his daughter, “Bui”. The sky turned dark and with it came a big rain which flooded the village. After he gave his daughter to the God, the rain stopped. After a year, the villagers had enough food and water to live on. They celebrated their good fortune with the Lego-Lego Dance and invited Bui to join them. Bui was believed to be married to the God of the mountain. While dancing, Bui asked her mother to take care of her baby that was wrapped in a blanket. She told her mother not to open the blanket. Despite her request, the mother opened the blanket and found a big red fish. She could not resist eating one of the eyes. When Bui discovered that the mother had hurt her baby, she ran and locked herself inside Bitu Era cave at the top of the mountain. She promised herself that there would be no more hunger and thirst for her family and village.

  • Birds of Atauro Island, Timor-Leste (East Timor)
    FORKTAIL 20 (2004): 41–48 Birds of Atauro Island, Timor-Leste (East Timor) COLIN R. TRAINOR and THOMAS SOARES Atauro island, Timor-Leste, lies between Timor,Wetar and Alor in the Lesser Sundas, but its avifauna was previously unknown. Five visits totalling 12 days in 2003–2004 resulted in 84 bird species being recorded. These included Timor Green Pigeon Treron psittacea (Endangered), Black Cuckoo Dove Turacoena modesta (Vulnerable) and four Near Threatened species: Pink-headed Imperial Pigeon Ducula rosacea, Beach Thick-knee Esacus neglectus, Malaysian Plover Charadrius peronii and Orange-sided Thrush Zoothera peronii.The avifauna appears to be most closely related to that of Timor, with the exception that the Olive-brown Oriole Oriolus melanotis is repre- sented by the Wetar race (finschi).

  • Loss of Morphology in Alorese (Austronesian): Simplification in Adult Language Contact
    journal of language contact 12 (2019) 378-403 brill.com/jlc Loss of Morphology in Alorese (Austronesian): Simplification in Adult Language Contact Francesca R. Moro Leiden University [email protected] Abstract This paper discusses historical and ongoing morphological simplification in Alorese, an Austronesian language spoken in eastern Indonesia. From comparative evidence, it is clear that Alorese lost almost all of its morphology over several hundred years as a consequence of language contact (Klamer, 2012, to appear). By providing both lin- guistic and cultural-historical evidence, this paper shows that Alorese has historically undergone morphological simplification as a result of second language (L2) learning. The first part of the paper presents a case study comparing the use of subject agree- ment prefixes in Alorese L1 speakers (n=6) and Alorese L2 speakers (n=12). The results show that L2 speakers deviate from the native norm, and tend to use one prefix as default agreement. The variation found among L2 speakers reveals an ongoing change possibly leading to the restructuring of the Alorese agreement system. The second part of the paper applies models of linguistic change (Kusters, 2003; Trudgill, 2011) to the Alorese community and shows that Alorese has been, and still is, spoken in a com- munity with a large number of L2 speakers, where morphological simplification is ex- pected to occur.
