Analysis of ticket price in the airline industry from the perspective of operating costs, supply and demand
Authors: Alves Udinelli , Caetano Mauro 
Published: January 2017

This study provides an analysis of airline ticket price and its determinants, such as operating costs, supply and demand. The research aimed to establish the relationship between ticket price and these influencing variables, using a correlation method to verify their effect. A linear regression model was developed using the least squares method to explain whether a causal relationship exists between the variables. The results show that, although a relationship does exist between airline ticket price and operating costs, it is overshadowed by the fact that the main determinant of pricing is explained by the relationship between supply and demand.*******************************************************************************************************************Preços de passagens aéreas analisados sob a perspectiva dos custos operacionais, oferta e demanda resumo Este estudo fornece uma análise do preço do bilhete de avião e seus determinantes, tais como os custos operacionais, a oferta e a demanda. O objetivo desta pesquisa consiste em determinar qual é a relação entre o preço do bilhete, o que a determina e qual destas variáveis a afetam, usando um método de correlação. Um modelo de regressão linear foi elaborado usando o método dos mínimos quadrados para explicar se existe uma relação causal entre as variáveis. Os resultados mostram que, apesar de existir uma relação entre o custo dos bilhetes de avião e os custos operacionais, essa relação é ofuscada devido ao fato de que o principal determinante do preço do bilhete é explicado pela relação entre a oferta e a demanda.Palavras-chave: indústria aérea; custos; demanda; preço.
DINAMIKA SPASIAL IKAN MESOPELAGIS (ceratoscopelus warmingii LÜTKEN, 1892) DI SAMUDERA HINDIA
Authors: Utama Andria Ansri , Wudianto Wudianto 
Published: January 2017

Kajian mengenai ikan mesopelagis di perairan Samudera Hindia masih sangat terbatas, sehingga informasi terkait kelimpahan jenis ikan mesopelagis di Samudera Hindia sangat penting. Survei trawl lapisan pertengahan dilakukan pada tanggal 26 Juni-16 Juli 2015 di perairan laut lepas (high seas) Samudera Hindia untuk memperoleh data dan informasi tersebut dengan menggunakan kapal penelitian R.V. Dr. Fridtjof Nansen. Hasil penelitian menunjukkan distribusi kedalaman vertikal di malam hari jenis yang dominan C.warmingii sesuai dengan kedalaman operasi trawl yaitu 86,9 ± 38,6 m. Namun pada siang hari tidak ditemukan spesies C. warmingii saat operasi trawl pada kedalaman rata-rata 444,3 ± 45,96 m. Diperkirakan ketika siang hari distribusi C. warmingii terkonsentrasi pada lapisan perairan lebih dalam sehingga tidak terjangkau oleh jaring trawl tersebut. Distribusi spasial secara horizontal pada malam hari menunjukkan pola konsentrasi tertinggi berada pada area gyre yang diindikasikan dengan pola geostrophic circulation. Sementara, prosentase C. warmingii yang merupakan hasil tangkapan seluruh stasiun trawl selama penelitian terdiri dari 2,58% fase larva, 27,21% juvenile, dan 60,21% dalam keadaan dewasa.Studies on mesopelagic fishes in the Indian Ocean are relatively limited, therefore data and information regarding spatial dynamic of the most abundant mesopelagic fish species Ceratoscopelus warmingii in the Indian Ocean would contribute a significant information on deepsea marine biodiversity. Pelagic-trawl stations were used to collect and identify the spatial dynamic of C. warmingii in the main scattering layers of the water column. Survey were carried out by RV Dr. Fridtjof Nansen in the high seas of Indian Ocean. Observation were made during day and night on 26th June to 16th July 2015 as part of the second International Indian Ocean Expedition (IIOE 2). The result shows that vertical distributions of C. warmingii were concentrated at the average depth 86.9 ± 38.6 m during nighttime. There were no individuals found during the daytime at the average depth 444.3 ± 45.96 m, diurnal migrations of C. warmingii to more than the depth of trawl operation might explain the absent of this species. Horizontal spatial distribution of trawl catches (number per hour) during nighttime show high concentration of C. warmingii close to gyre indicated by geostrophic circulation. Moreover, the total catches of C. warmingii across the Indian Ocean are dominated by 60.21% adult, 27.21% juvenile, and 2.58% larvae, respectively.
EFEKTIFKAH DAERAH PERLINDUNGAN LAUT (DPL)MENGKONSERVASI IKAN KARANG?STUDI KASUS DI KABUPATEN BIAK-NUMFOR DAN SUPIORI, PAPUA

Published: January 2017

Sumber daya ikan karang (SDIK) dari salah satu ekosistem tropika wilayah pesisir yang sangat produktif, namun hingga kini belum diketahui stoknya, sehingga menyebabkan pengelolaan berkelanjutan sulit dilakukan,meskipun kawasan konservasi perikanan (Daerah Perlindungan Laut, DPL)sudah banyak didirikan. Tujuan kajian ini adalah mengetahui keefektifan DPL dalam konservasi SDIK di Kabupaten Biak-Numfor, dan Supiori melalui pembandingan stok SDIK dalam bentuk densitas ikan (ekor/m2) di DPL dan di luar DPL. Hasil kajian menunjukkan bahwa SDIK (ikan Target, Indikator dan Mayor) menurun drastis hampir di semua lokasi kajian, akibat pemanfaatan yang tidak ramah lingkungan pada 1995, 2001 dan 2010-2012.Perbandingan densitas SDIK di luar DPL pada 2010-2012 dan di 20 lokasi DPL tradisonal yang didirikan masyarakat di wilayah kerja Coremap LIPI pada 2008 menunjukkan bahwa densitas SDIK ikan Target, Indikator dan Mayor di DPL masing-masing lebih tinggi 3-4 kali, 3-5 kali dan 2-3 kali. DPL tradisional terbukti efektif mengkonservasi SDIK, oleh karenanya pendirian DPL perlu terus dilanjutkan di banyak lokasi, seperti target pemerintah yang akan mendirikan 20 juta ha DPL hingg 2020. DPL yang telah ada juga perlu dipantau dan dirawat secara periodik agar efektif mengkonservasi SDIK. The reef fishes resources produced from one of productive tropical ecosystem in the coastal zones have not well known yet. Thus, it is difficult to conduct sustainable management on reef fishes, desipite there are many sanctuaries (DPL) have been established in Indonesia waters. This paper aims to assess the effectiveness of DPL in the Biak-Numfor and Supiori Districts by comparing the reef fish stocks expressed as fish density (individuals/m2) between areas inside and outside DPL. Results show that the reef fish stocks (Target, Indicator and Major group) were drastically decreased in almost of study sites due to over exploitation and environmentally unfriendly fishing practises during 1995, 2001 to 2010-2012. Comparison of reef fishes density between outside DPL in 2010-2012 and inside of the 20 locations of traditional DPL established by local communities in 2008 within the Coremap LIPI working areas indicated that the density of reef fishes are 3-4, 3-5 and 2-3 times higher for Target, Indicator, and Major fish groups, respectively. Traditional DPL proves its role and its effectiveness as one of conservation tool to increase the reef fish stocks abundance Threfore, it is needed to estabish more DPL which have been targeted by government to reach 20 million ha of DPL by 2020. The exsisting DPL should be always be maintained in order they are effective in protecting the reef fish resources.

Published: January 2017

<p class="abstract"><strong>Background:</strong> Illegal trade of rhinoceros horn in the global market has posed a serious threat to the long-term survival and the conservation of endangered one horn rhinoceros. Presence of fake horns imitating rhinoceros horn makes the situation graver. Thus, to curb the trade it is very important to scientifically identify the horns used in trade to support and strengthen the enforcement agencies. The presence of fake items makes the identification task much more difficult thus, a project entitled “Characterization of species from bone, tusk, rhino horn and antler to deal wildlife offence cases” was developed to identify rhinoceros (<em>Rhinoceros unicornis</em>) horn in complete to pulverized form.</p><p class="abstract"><strong>Methods:</strong> Various bio-scientific techniques like morphological, analytical and molecular were applied to identify the rhinoceros horn. Most of these techniques are promising in identifying rhinoceros horn in different forms. In present paper, we discuss on identification of a piece of rhinoceros horn using Scanning Electron Microscope and total nine<strong> </strong>horns were examined.<strong> </strong>The required micrographs were saved using software Digital Image Scanning System (DISS 5, Point Electronics, Germany). Scanned images for both rhinoceros horn from wild and zoo were similar. To find the specific signature, the micrographs of the rhinoceros horn were compared with buffalo and fake horns<span lang="EN-IN">. </span><span lang="EN-IN"> </span></p><p class="abstract"><strong>Results:</strong> Differences were noted on both dorsal and ventral surfaces of rhinoceros horns examined under scanning electron microscope. On ventral surface numerous uniformly placed circular pores with mean diameter of 320 µm and had characteristic “sub pores within a pore”. Instead, in fake horn only few non-uniform pores were visible without any sub pores. The ventral portion of buffalo horn does not indicate presence of any such pores.</p><p class="abstract"><strong>Conclusions:</strong> The characteristic “sub pores within a pore” signature of the ventral portion of rhinoceros horn has high potential for forensic identification and consequently, proving offences and convicting offenders<span lang="EN-IN">. </span></p>

Published: January 2017

<p class="abstract"><strong>Background:</strong> Sequel to the diverse diseases resulting in muscle mass degeneration and its key role in the prognosis of the diseases. For instance, currently, only resistance exercise can be used to promote recovery of mass/strength following disuse atrophy. But in contrast, many patients are unable or unwilling to exercise at a sufficient intensity to promote muscle growth. It would therefore be of great advantage to develop natural compounds that counteract the negative effects of skeletal muscle degenerative diseases especially in the form of therapeutic feed). The present study was aimed at elucidating the mechanism by which <em>M. oleifera</em> ameliorates skeletal muscle degeneration caused by malnutrition.</p><p class="abstract"><strong>Methods:</strong> The experimental animals were malnourished with low protein iso-caloric diets for four weeks after which they were treated with 25% <em>M. oleifera</em> leaf – based diet, vitamin E supplemented feed and soy bean based- diet for another four weeks<span lang="EN-IN">. </span><span lang="EN-IN"> </span></p><p class="abstract"><strong>Results:</strong> There was a significant reduction in the activity of calcium ATPase in the skeletal muscle of animals induced with skeletal muscle degeneration. However, this activity was significantly increased following treatments with the most significant increase observed in the skeletal muscle of animals treated with <em>M. Oleifera</em> leaf based diet followed by those fed with vitamin E supplemented diet.</p><p class="abstract"><strong>Conclusions:</strong> In summary, the study revealed that the mechanism by which <em>M. oleifera</em> leaf corrects muscle degeneration caused by PEM might be by increasing calcium ATPase activity and/ or its synthesis and by preventing oxidative stress due to its antioxidant properties<span lang="EN-IN">. </span></p>

Published: January 2017

A sexualidade compreende aspectos biológicos, psicológicos e socioculturais. Ela é desenvolvida ao longo da vida e inicia-se a partir das primeiras experiências afetivas do bebê. Objetivando compreender o entendimento de sexualidade dos professores de centro de apoio à deficientes auditivos, foi aplicado um questionário semi-estruturado. Todos foram unanimes quanto a importância da temática sexualidade ser trabalhada na escola. Quando questionados se já trabalharam a temática sexualidade em sala de aula a maioria disse que sim, e uma minoria disse que não. Dentro os que responderam abordar a temática em sala de aula, foram relatados os assuntos mais abordados: prevenção de Doenças Sexualmente Transmissíveis e gravidez indesejada, diversidade sexual e de gênero. Os recursos mais usados pelos professores são palestras/oficinas com profissionais da área e filmes/documentários. Percebe-se a necessidade de uma prática interdisciplinar no que toca à sexualidade, e de que todos os profissionais da educação estejam preparados para falar, partindo, ou não, do conteúdo de suas disciplinas.Palavras-chave: Sexualidade; Educação; Professores; Alunos surdos. ABSTRACT: The sexuality includes biological, psychological and sociocultural aspects. It is developed throughout life and starts from the first affective experiences of the baby. Aiming to understand the apprehension of sexuality a questionnaire was applied to teachers of a deaf support center. All were unanimous about the importance of the sexuality be worked at school. When asked if they have worked the theme sexuality in the classroom the majority said yes, and a minority said no. Inside the respondents address the issue in the classroom, the most discussed topics were reported: prevention of sexually transmitted diseases and unwanted pregnancies, sexual and gender diversity. The funds most used by teachers are lectures/workshops with professionals and films/documentaries. We realize the need for an interdisciplinary practice when it comes to sexuality, and that all education professionals are prepared to talk, starting or not the content of their disciplines.Keywords: Sexuality; Education; Teachers; Deaf students.
