Abstract
Biological diversity is inextricably linked to community stability and ecosystem functioning, but our understanding of these relationships in freshwater ecosystems is largely based on short-term observational, experimental, and modelling approaches. Using a multidecadal diatom record for the past ca. 16 000 years from Lake Baikal, we investigate how diversity and palaeoproductivity have responded to climate change during periods of both rapid climate fluctuation and relative climate stability. We show dynamic changes in diatom communities during the past 16 000 years, with decadal shifts in species dominance punctuating millennial-scale seasonal trends. We describe for the first time in Lake Baikal a gradual shift from spring to autumnal diatom communities that started during the Younger Dryas and peaked during the Late Holocene, which likely represents orbitally driven ecosystem responses to long-term changes in seasonality. Using a multivariate classification tree, we show that trends in planktonic and tychoplanktonic diatoms broadly reflect both long-term climatic changes associated with the demise of Northern Hemisphere ice sheets and abrupt climatic changes associated with, for example, the Younger Dryas stadial. Indeed, diatom communities are most different before and after the boundary between the Early and Middle Holocene periods of ca. 8.2 cal kyr BP, associated with the presence and demise of Northern Hemisphere ice sheets respectively. Diatom richness and diversity, estimated using Hill's species numbers, are also shown to be very responsive to periods characterized by abrupt climate change, and using knowledge of diatom autecologies in Lake Baikal, diversity trends are interpreted in 30
terms of resource availability. Using diatom biovolume accumulation rates (BVARs; μm^3 cm^-2 yr^-1), we show that spring diatom crops dominate palaeoproductivity for nearly all of our record, apart from a short period during the Late Holocene, when autumnal productivity dominated between 1.8–1.4 cal kyr BP. Palaeoproductivity was especially unstable during the Younger Dryas, reaching peak rates of 18.3 x 10^3 μm^3 cm^-2 yr^-1 at ca. 12.3 cal kyr BP. Generalized additive models (GAMs), which explore productivity–diversity relationships (PDRs) during pre-defined climate periods, reveal complex relationships. The strongest statistical evidence for GAMs were found during the Younger Dryas, the Early Holocene, and the Late Holocene, i.e. periods of rapid climate change. We account for these differences in terms of climate-mediated resource availability, and the ability of endemic diatom species in Lake Baikal to adapt to extreme forms of living in this unique ecosystem. Our analyses offer insight into how productivity–diversity relationships may develop in the future under a warming climate

PERANCANGAN BUKU ILUSTRASI LUDRUK IRAMA BUDAYA SINAR NUSANTARA BAGI ANAK TINGKAT SEKOLAH DASAR (SD) SEBAGAI PELESTARIAN DAN PROMOSI BUDAYA LOKAL DI SURABAYA
No full textRINGKASAN Baby, Vivian. 2019. Perancangan Buku Ilustrasi Ludruk Irama Budaya Sinar Nusantara Bagi Anak Tingkat Sekolah Dasar (SD) Sebagai Pelestarian Dan Promosi Budaya Lokal Di Surabaya. Skripsi, Jurusan Seni dan Desain, Fakultas Sastra, Universitas Negeri Malang. Pembimbing: (I) Dr. Pujiyanto, M.Sn., (II) Andreas Syah Pahlevi, S.Sn, M.Sn. Kata Kunci: Buku, Ilustrasi, Strategi Promosi, Ludruk, Pelestarian Budaya Lokal. Kemajuan teknologi memberi dampak bagi sikap masyarakat terhadap kesenian tradisional ludruk (seni pertunjukan drama). Ludruk yang pada masanya menjadi icon kota pahlawan ini sekarang tidak diminati lagi. Masyarakat menganggap ludruk sebagai hiburan kuno dan tidak menarik. Ludruk yang masih bertahan ditengah sepinya apresiasi masyarakat terhadap kesenian tradisional kota Surabaya adalah Irama Budaya Sinar Nusantara. Ludruk Irama Budaya Sinar Nusantara menjadi ludruk satu-satunya di Surabaya yang rutin melakukan pentas setiap minggunya dan selalu membuat inovasi pada tema cerita yang disesuaikan dengan kehidupan saat ini, tetapi dengan semangat dan potensi itu sangat disayangkan Irama Budaya Sinar Nusantara belum memiliki strategi promosi yang tepat dan maksimal untuk meningkatkan ketertarikan target audience terhadap kesenian tradisional dan mengubah image kuno ludruk, sehingga mampu menghasilkan regenerasi baru yang mempertahankan eksistensi ludruk dimasa mendatang. Perancangan buku ilustrasi ini menggunakan model perancangan prosedural yang bersifat deskriptif, mengacu pada proses perancangan Sanyoto yang dikembangan sesuai dengan permasalahan yang dihadapi dan penyelesaian yang dibutuhkan. Hasil data yang diperoleh berasal dari wawancara dengan ketua pengelola Ludruk Irama Budaya Sinar Nusantara dan Wakil Ketua Dewan Kesenian Jawa Timur, observasi tempat pertunjukan dan media promosi yang ada, kepustakaan dari beberapa karya tertulis, serta angket yang diisi oleh pengelola dan penonton ludruk. Model perancangan ini diawali dengan merumuskan latar belakang, permasalahan, dan tujuan. Data yang diperoleh diidentifikasi dan dianalisis yang menghasilkan sintesis sebagai dasar pertimbangan penentuan konsep perancangan, visualisasi desain, proses produksi hingga final artwork. Perancangan ini menghasilkan media utama dan media pendukung yang menunjang media utama. Media Utama dari perancangan ini adalah buku ilustrasi Ludruk Irama Budaya Sinar Nusantara yang terdiri dari 5 konten yaitu sejarah ludruk Jawa Timur, sejarah Ludruk Irama Budaya Sinar Nusantara, urutan tampilan pembuka ludruk, cerita ludruk anak Lautku Lautmu Laut Kita, dan pop art panggung ludruk. Media pendukung yang menunjang buku ilustrasi sebagai media utama perancangan ini adalah rak display, poster, x-banner, pencil case, dan notebook yang dikemas dengan konsep strategi launching buku dan mini roadshow dibeberapa sekolah dasar. SUMMARY Baby, Vivian. 2019. Designing Book Illustration Ludruk Irama Budaya Sinar Nusantara for Elementary School Children as a Preservation and Local Culture Promotion in Surabaya. Thesis, Department of Art and Design, Faculty of Letters, State University of Malang. Advisors: (I) Dr. Pujiyanto, M.Sn., (II) Andreas Syah Pahlevi, S.Sn, M.Sn. Keyword: Book, Illustration, Promotion Strategy, Ludruk, Preservation of Local Culture. Technological advances have an impact on people's attitudesabout ludruk traditional arts (drama performing arts). Ludruk which used to be an icon of the city of heroes is now no longer in demand. People assume that this art is an old-fashioned and uninteresting entertainment. Ludruk which still survives amid the lack of public appreciation for traditional arts in the city of Surabaya is " Ludruk Irama Budaya Sinar Nusantara ". "Ludruk Irama Budaya Sinar Nusantara" is the only ludruk in Surabaya that routinely performs every week and always innovates on the theme of the story that is adjusted to current habits, but with enthusiasm and potential it is unfortunate that Ludruk Irama Budaya Sinar Nusantara does not have a promotional strategy the right and the maximum to increase the target audience's interest in traditional arts and to change the ancient image of ludruk, so that it can produce new regenerations that maintain the existence of ludruk in the future. The design of this illustration book uses a descriptive procedural design model, referring to Sanyoto's design process which was developed in accordance with the problems faced and the solutions needed. The results of the data obtained came from interviews with the manager of the Ludruk Irama Budaya Sinar Nusantara and Deputy Chair of the East Java Arts Council, observing the venue and the existing promotional media, a library of several written works, and a questionnaire filled by managers and audience members. This design model begins with formulating the background, problems, and objectives. The data obtained were identified and analyzed which resulted in synthesis as a basis for consideration of determining design concepts, design visualization, production process to final artwork. This design produces the main media and supporting media that support the main media. The main media of this design is a book that describes Ludruk Irama Budaya Sinar Nusantara which is consists of 5 content, namely the history of East Java, history of Ludruk Irama Budaya Sinar Nusantara , the opening of ludruk, the story of ludruk kids Lautku Lautmu Lautmu Laut Kita, and pop art ludruk perfomance. Supporting media that support illustration books as the main media for this design are display cabinets, posters, x-banners, pencil cases, and notebooks that are packaged with the concept of book launching and mini roadshow strategies in some elementary schools

A multidimensional ecological momentary assessment analysis of relations among negative affect, craving, and smoking cesation failure
No full textCessation failure occurs when smokers lapse within 24 hours of initiating a quit attempt. Although avoiding cessation failure is the first milestone of successful smoking cessation, little is known about the risk factors that influence cessation failure. This study examined whether or not multiple dimensions of real-time ratings of pre-quit negative affect and craving differentiated cessation failures from quit day abstainers. We hypothesized that cessation failures would experience greater severity, accelerated growth, and higher volatility in negative affect and craving in the two weeks preceding the target quit day than would successful abstainers. Results indicated that cessation failures and quit day abstainers did not differ in pre-quit dimensions of negative affect and craving. Those who failed to quit, however, experienced a greater reduction in craving after smoking during the 24 hours and four days before the target quit day than did successful quitters. The contingency between smoking and craving relief may indicate cessation failure risk in a way that pre-quit negative affect and craving trajectories and volatility do not.M.S.Includes bibliographical referencesby Vivian M Ye
