La vida a la frontera. El limes britannicus

Treballs Finals de Grau en Història, Facultat de Geografia i Història, Universitat de Barcelona, Curs: 2013-2014, Tutor: Maria Dolors Molas FontLa investigació arqueològica de les fortaleses i els assentaments civils localitzats al llarg de la frontera, tan a un costat com a l’altre del mur, permet formular noves hipòtesis d’estudi sobre la situació fronterera al nord de Britania. Cada dia es produeixen nous descobriments que permeten una nova perspectiva sobre la vida a la frontera, especialment en els aspectes més desconeguts o més difícils de conèixer, l’àmbit quotidià i la relació amb els nadius del nord del mur

What makes re-finding information difficult? A study of email re-finding

Re-nding information that has been seen or accessed before is a task which can be relatively straight-forward, but often it can be extremely challenging, time-consuming and frustrating. Little is known, however, about what makes one re-finding task harder or easier than another. We performed a user study to learn about the contextual factors that influence users' perception of task diculty in the context of re-finding email messages. 21 participants were issued re-nding tasks to perform on their own personal collections. The participants' responses to questions about the tasks combined with demographic data and collection statistics for the experimental population provide a rich basis to investigate the variables that can influence the perception of diculty. A logistic regression model was developed to examine the relationships be- tween variables and determine whether any factors were associated with perceived task diculty. The model reveals strong relationships between diculty and the time lapsed since a message was read, remembering when the sought-after email was sent, remembering other recipients of the email, the experience of the user and the user's ling strategy. We discuss what these findings mean for the design of re-nding interfaces and future re-finding research

HUBUNGAN MORFOMETRIK OTOLITH DENGAN UKURAN IKAN LAYANG DELES (Decapterus macrosoma Bleeker, 1851) DI PERAIRAN BALI SELATAN

Ikan layang merupakan komoditas ekonomis penting dari famili Carangidae yang banyak tertangkap di perairan Bali Selatan. Otolith ikan dimanfaatkan secara luas untuk mengaji taksonomi, pertumbuhan, umur dan kekerabatan populasi ikan dari perairan yang berbeda. Penelitian ini bertujuan untuk mengetahui hubungan antara morfometrik otolith dan ukuran ikan layang serta ciri-ciri morfologi otolith. Sampel dikumpulkan dari Pangkalan Pendaratan Ikan (PPI) Kedonganan dan Pelabuhan Perikanan Nusantara (PPN) Pengambengan, Bali Selatan antara 7 Maret s/d 5 April 2020. Sampel ikan layang deles diambil secara acak (random sampling) dari hasil tangkapan pukat cincin yang beroperasi secara harian. Pengambilan sagittae dilakukan dengan cara “up through the gill”. Secara keseluruhan digunakan 83 pasang sampel otolith sagittae utuh yang berhasil diambil dari bagian kepala ikan layang deles. Hubungan morfometrik otolith dan ukuran ikan dianalisis menggunakan persamaan regresi linear y= ax + b. Hasil penelitian menunjukkan bahwa tidak ada perbedaan yang signifikan antara morfometri otolith kiri dan kanan. Ukuran otolith memiliki korelasi isometrik dengan pertumbuhan ikan, dalam arti panjang otolith (OL) menjadi indikator terbaik untuk mengestimasi ukuran individu ikan layang Decapterus macrosoma.Shortfin scad (Decapterus macrosoma) is an important economic commodity from the Carangidae family which is mostly caught in South Bali waters. Fish otoliths are widely used to assess the taxonomy, growth, age, and relationships of fish populations from different waters. This study aims to determine the relationship between otolith morphometrics and the size of the flying fish as well as the morphological characteristics of the otoliths. Samples were collected from the Kedonganan Fish Landing Base (PPI) and Pengambengan Archipelago Fishery Port (PPN), South Bali between March 7 to April 5, 2020. The deles fly fish sample was taken randomly (random sampling) from the catch of ring trawlers that operate in an automated manner. Daily. Sagittae collection is done by "up through the gill". Overall, 83 pairs of intact otolith sagittae samples were used which were successfully taken from the head of the deles flying fish. Otolith morphometric relationships and fish size were analyzed using the linear regression equation y = ax + b. The results showed that there was no significant difference between the morphometry of the left and right otoliths. Otolith size has an isometric correlation with fish growth, in the sense that otolith length (OL) is the best indicator to estimate the individual size of Decapterus macrosoma flying fish

REPRODUCTIVE BIOLOGY OF THE RED BIGEYE (Priacanthus macracanthus Cuvier, 1829) IN PALABUHANRATU BAY, INDONESIA

The reference point of reproductive biology play an important roles in developing a baseline information for fishery management. Different waters will provide different overview of fisheries related to its biological aspects. The red bigeye (Priacanthus macracanthus) is one of economically important demersal fish species in Indonesia. To support the biological status of this species, a regular field observation were carried out during May 2016 to April 2017 in Palabuhanratu bay, south of West Java. The objective of this study is to estimate the spawning season and potential reproductive stages including to evaluate how the key management related to the species and its gear selectivity. Numbers of red bigeye (Priacanthus macracanthus) specimen was collected from bottom gillnetter and hand liner. Basic information related to length-weigth, bio-reproduction (maturity) were collected regularly to determine GSI, Fecundity and its impact of fishing (Lc, Lm) to evaluate the recent stock status. The result showed sex ratio no significant differences between males and females except in September to December. The growth pattern indicated negative allometric. The predicted of spawning seasons were around June-July and December-January. Mean of fecundity was estimated to be 230,000 ± 178,000 eggs. Management keys were obtained i.e. length at first maturity (Lm) value was to be 21.9 cm TL which is smaller than length at first capture (Lc) 22.4 cm TL for bottom gill netter and 23.1 cm TL for average fishes caught by hand liner. Therefore it is recommended to close the waters in the bay area during the spawning period. In the case of catch, it is important to apply the precautionary approach with emphasizes to the size of fish allowed to be captured more than the Lm value (above 21.9 cm TL).

ICADA: indice de calidad acústica de la arquitectura interior

ICADA es una propuesta de desarrollo de un Índice de Calidad Acústica Arquitectónica que sintetice en forma numérica el nivel de confort de un local interior. El proceso de obtención de ICADA se basa en una herramienta matemática que, gracias a su innovadora estructura matricial, permite involucrar un número variable de aspectos relevantes que determinan la acústica de un local, como el nivel de ruido de fondo, la inteligibilidad de la palabra, los materiales constitutivos del revestimiento, la geometría espacial, etc. El método de cálculo sobre el que se basa ICADA se pretende que sea adaptable a cualquier clase de edificio o uso arquitectónico estudiado, que su implementación se pueda realizar “in situ” y que su uso sea accesible a personas no necesariamente especializadas en acústica pero si en arquitectura. ICADA tiene diversas utilidades: puede utilizarse como sello de acreditación de la calidad acústica en el momento de comparar varios locales existentes; se revela también como un instrumento válido para detectar la jerarquía de los problemas acústicos que presenta un espacio a rehabilitar e incluso, en fase de proyecto, puede servir para comparar la eficiencia de dos alternativas posibles de intervención.

Skema Kemitraan kehutanan merupakan salah satu bentuk program pemberdayaan masyarakat di dalam dan sekitar hutan. Skema ini diharapkan mendukung peningkatan akses masyarakat terhadap kawasan hutan, khususnya pada areal hutan yang pengelolaannya telah diberikan kepada pemegang ijin dan pengelola hutan, dalam hal ini Kesatuan Pengelolaan Hutan (KPH). Selain itu diharapkan dapat menjadi alternatif pengembangan kerjasama antara Perusahaan dengan masyarakat sehingga dapat mengatasi sengketa dan atau konflik lahan hutan
