Perancangan Public Service Announcement Anti Rokok Bagi Remaja Usia 15 – 19 Tahun

Indonesia merupakan Negara konsumen tembakau terbesar nomor 5 di Dunia. Di Surabaya, sebanyak 23% remajanya merupakan perokok aktif dengan motivasi merokok dikarenakan oleh pengaruh lingkungan dan kebiasaan interaksi dengan perokok. 28% remaja mengaku tetap merokok karena kurangnya media yang mampu memotivasi mereka untuk berhenti merokok, oleh karena itu dirancanglah sebuah kampanye Public Service Announcement (PSA) yang mampu memotivasi mereka untuk berhenti merokok. PSA adalah proses penyampaian pesan sosial yang bertujuan untuk membangkitkan kepedulian masyarakat terhadap sejumlah masalah yang harus mereka hadapi. Metodologi riset yang digunakan berawal dari proses penggalian data mengenai fenomena, identifikasi masalah, rumusan masalah serta solusi yang dipelajari melalui studi eksisting, literatur, penggalian data secara primer dan sekunder. Setelah proses pencarian data, langkah selanjutnya adalah menentukan ide kampanye yang akan di turunkan pada konsep komunikasi, visual dan media. Proses perancangan PSA ini memiliki konsep mengajak remaja untuk berhenti merokok dengan tagline “Mandheg Yok Rek!”. Konsep yang dimiliki di dapatkan dari pengamatan perilaku target audiens. Tagline menggunakan bahasa khas daerah Surabaya dengan maksud untuk dapat mendekatkan diri dengan target audiens yang merupakan remaja – remaja Surabaya. Diharapkan kampanye ini dapat menumbuhkan motivasi remaja perokok untuk dapat mengurangi angka perokok aktif di Surabaya

Mapping of forests based on biological diversity to identify conservation sites: A case study from Udupi and South Canara districts of Karnataka

Forest classification is traditionally based on the structure and composition of vegetation, which in tum is strongly linked with the climatic profile of the area. Forest maps thus prepared cannot appropriately meet the needs of the managers whose renewed mandate is to conserve the biological richness of the forests. The emerging need for protecting the forests is to understand the spatial distribution of the conservation value of the forests besides knowing their vegetation types. In other words, we need maps that depict the spatial distribution of biological diversity of the forests. In this paper, we rep011 on our attempt to develop such biodiversity maps for the forest ranges of Udupi and South Canara districts of Ka.rnataka state. Utilizing the data from the vegetation sampling of the Forest Survey of India, we developed a terrain view of the density and diversity of tree species and have attempted to identify the sites with the highest conservation value. We propose that such maps be developed for the entire country and discuss the potentialities and problems associated with this protocol

Do Ecological Niche Model Predictions Reflect the Adaptive Landscape of Species?: A Test Using Myristica malabarica Lam., an Endemic Tree in the Western Ghats, India

Ecological niche models (ENM) have become a popular tool to define and predict the “ecological niche” of a species. An implicit assumption of the ENMs is that the predicted ecological niche of a species actually reflects the adaptive landscape of the species. Thus in sites predicted to be highly suitable, species would have maximum fitness compared to in sites predicted to be poorly suitable. As yet there are very few attempts to address this assumption. Here we evaluate this assumption. We used Bioclim (DIVA GIS version 7.3) and Maxent (version 3.3.2) to predict the habitat suitability of Myristica malabarica Lam., an economically important tree occurring in the Western Ghats, India. We located populations of the trees naturally occurring in different habitat suitability regimes (from highly suitable to poorly suitable) and evaluated them for their regeneration ability and genetic diversity. We also evaluated them for two plant functional traits, fluctuating asymmetry – an index of genetic homeostasis, and specific leaf weight – an index of primary productivity, often assumed to be good surrogates of fitness. We show a significant positive correlation between the predicted habitat quality and plant functional traits, regeneration index and genetic diversity of populations. Populations at sites predicted to be highly suitable had a higher regeneration and gene diversity compared to populations in sites predicted to be poor or unsuitable. Further, individuals in the highly suitable sites exhibited significantly less fluctuating asymmetry and significantly higher specific leaf weight compared to individuals in the poorly suitable habitats. These results for the first time provide an explicit test of the ENM with respect to the plant functional traits, regeneration ability and genetic diversity of populations along a habitat suitability gradient. We discuss the implication of these resultsfor designing viable species conservation and restoration programs

Predicting the potential geographical distribution of the sugarcane woolly aphid using GARP and DIVA-GIS

Management of newly emerging pests and diseases has often been limited by the lack of forecasting systems that could predict the route(s) of spread and potential geographical distribution of the species. While the importance of the patterns of spread of invasive organisms has always been realized, the necessary analytical tools for making reasonably robust predictions are limited. In recent years however, availability of ecological and climatologic data,computational abilities to process huge data sets, and development of suitable algorithms have helped in a better understanding of the patterns of spread of the invasive species. For instance, algorithms such as Genetic Algorithm for Rule Set Prediction (GARP) and DIVA-GIS, are being successfully employed in a wide range of situations for predicting the spread of invasive species1–4. Here, we explore these two modelling approaches to predict the potential geographical distribution of a newly emerging insect pest, the sugarcane woolly aphid that has played havoc with crops in parts of Maharashtra and Karnataka5

Research applications of primary biodiversity databases in the digital age

Our world is in the midst of unprecedented change-climate shifts and sustained, widespread habitat degradation have led to dramatic declines in biodiversity rivaling historical extinction events. At the same time, new approaches to publishing and integrating previously disconnected data resources promise to help provide the evidence needed for more efficient and effective conservation and management. Stakeholders have invested considerable resources to contribute to online databases of species occurrences. However, estimates suggest that only 10% of biocollections are available in digital form. The biocollections community must therefore continue to promote digitization efforts, which in part requires demonstrating compelling applications of the data. Our overarching goal is therefore to determine trends in use of mobilized species occurrence data since 2010, as online systems have grown and now provide over one billion records. To do this, we characterized 501 papers that use openly accessible biodiversity databases. Our standardized tagging protocol was based on key topics of interest, including: database(s) used, taxa addressed, general uses of data, other data types linked to species occurrence data, and data quality issues addressed

Acknowledging uncertainty in evolutionary reconstructions of ecological niches

Reconstructing ecological niche evolution can provide insight into the biogeography and diversification of evolving lineages. However, comparative phylogenetic methods may infer the history of ecological niche evolution inaccurately because (a) species' niches are often poorly characterized; and (b) phylogenetic comparative methods rely on niche summary statistics rather than full estimates of species' environmental tolerances. Here, we propose a new framework for coding ecological niches and reconstructing their evolution that explicitly acknowledges and incorporates the uncertainty introduced by incomplete niche characterization. Then, we modify existing ancestral state inference methods to leverage full estimates of environmental tolerances. We provide a worked empirical example of our method, investigating ecological niche evolution in the New World orioles (Aves: Passeriformes: Icterus spp.). Temperature and precipitation tolerances were generally broad and conserved among orioles, with niche reduction and specialization limited to a few terminal branches. Tools for performing these reconstructions are available in a new R package called nichevol

Ab initio linear response and frozen phonons for the relaxor PMN (PbMg1/3Nb2/3O3)

We report first principles density functional studies using plane wave basis sets and pseudopotentials and all electron linear augmented plane wave (LAPW) of the relative stability of various ferroelectric and antiferroelectric supercells of PMN for 1:2 chemical ordering along [111] and [001]. We used linear response with density functional perturbation theory (DFPT) as implemented in the code ABINIT to compute the Born effective charges, electronic dielectric tensors, long wavelength phonon frequencies and LO-TO splittings. The polar response is different for supercells ordered along [111] and [001]. Several polar phonon modes show significant coupling with the macroscopic electric field giving giant LO-TO splittings. For [111] ordering, a polar transverse optic (TO) mode with E symmetry is found to be unstable in the ferroelectric P3m1 structure and the ground state is found to be triclinic. Multiple phonon instabilities of polar modes and their mode couplings provide the pathway for polarization rotation. The Born effective charges in PMN are highly anisotropic and this anisotropy contributes to the observed huge electromechanical coupling in PMN solid solutions.Comment: 34 pages, 6 figures. to appear in PR

Geometric frustration in compositionally modulated ferroelectrics

Geometric frustration is a broad phenomenon that results from an intrinsic incompatibility between some fundamental interactions and the underlying lattice geometry1-7. Geometric frustration gives rise to new fundamental phenomena and is known to yield intriguing effects, such as the formation of exotic states like spin ice, spin liquids and spin glasses1-7. It has also led to interesting findings of fractional charge quantization and magnetic monopoles5,6. Geometric frustration related mechanisms have been proposed to understand the origins of relaxor behavior in some multiferroics, colossal magnetocapacitive coupling and unusual and novel mechanisms of high Tc superconductivity1-5. Although geometric frustration has been particularly well studied in magnetic systems in the last 20 years or so, its manifestation in the important class formed by ferroelectric materials (that are compounds exhibiting electric rather than magnetic dipoles) is basically unknown. Here, we show, via the use of a first-principles-based technique, that compositionally graded ferroelectrics possess the characteristic "fingerprints" associated with geometric frustration. These systems have a highly degenerate energy surface and exhibit original critical phenomena. They further reveal exotic orderings with novel stripe phases involving complex spatial organization. These stripes display spiral states, topological defects and curvature. Compositionally graded ferroelectrics can thus be considered as the "missing" link that brings ferroelectrics into the broad category of materials able to exhibit geometric frustration. Our ab-initio calculations allow a deep microscopic insight into this novel geometrically frustrated system.Comment: 14 pages, 5 Figures; http://www.nature.com/nature/journal/v470/n7335/full/nature09752.htm
