Kajian komposisi dan pengasingan sisa pepejal di kawasan perumahan
No full textTaraf ekonomi yang semakin meningkat dan peningkatan jumlah penduduk menjadi antara faktor pendorong kepada peningkatan jumlah sisa pepejal di sesuatu kawasan. Lambakan ini secara umumnya akan memberi ke atas alam sekitar, terutamanya di kawasan bandar dan petempatan penduduk. Situasi semasa menunjukkan isu penjanaan dan komposisi sisa pepejal semakin membimbangkan, terutamanya di negara-negara membangun seperti Malaysia. Kajian ini bertujuan mengenal pasti komposisi sisa di kawasan perumahan dengan menggunakan pendekatan yang digunakan dalam Akta 672. Kaedah survei yang digunakan dalam kajian ini melibatkan sebanyak 100 orang responden kajian yang dipilih secara rawak daripada dua kawasan perumahan iaitu Taman Megah Jaya dan Kampong Rawa-Rawa. Kajian komposisi dilakukan melalui pengasingan dan penimbangan secara terus. Hasil kajian mendapati, wujud perbezaan jumlah sisa baki dan sisa kitar semula di kedua-dua kawasan. Walaupun perbezaan yang didapati tidak ketara, responden di kawasan perumahan kampung lebih cenderung untuk melakukan pengasingan sisa boleh kitar berbanding mereka yang tinggal di kawasan perumahan taman. Faktor kewangan diandaikan sebagai pendorong utama untuk mereka melakukan pengasingan dengan sebahagian besar daripada mereka menjual sisa kitar semula yang dikumpul. Oleh itu, aktiviti ini perlu diberi perhatian serius oleh semua pihak dengan mengadakan usaha sama agar sisa kitar semula dapat diguna semula oleh pihak industri
Kajian komposisi sisa pejal di kawasan perumahan terpilih di Tawau, Sabah
No full textMasalah pengurusan sisa sudah semakin kritikal berikutan kesan buruk terhadap alam sekitar. Kawasan perumahan dikenalpasti sebagai punca utama peningkatan jumlah sisa. Oleh itu, untuk mengurangkan kesan buruk tersebut, penglibatan masyarakat perlu dilaksanakan. Kajian ini bertujuan mengenalpasti komposisi sisa di kawasan perumahan di daerah Tawau. Selain itu kajian ini juga ingin mengenalpasti penglibatan penduduk dalam aktiviti pengasingan sisa. Untuk itu kajian ini telah menggunakan dua kaedah iaitu temuramah dan pengukuran di kawasan kajian. Hasil kajian mendapati komposisi seperti kertas, kaca, plastik dan sisa makanan adalah antara sampah utama yang dibuang oleh responden setiap hari. Responden mengandaikan kira-kira 2.9kg sampah dibuang setiap hari. Kajian ini juga mendapati 59.5% responden tidak pernah melakukan pengasingan sisa. Sebahagian besar (66%) responden menjalankan pengasingan untuk mendapatkan pulangan ekonomi. Amalan tersebut juga menguntungkan dari aspek alam sekitar di samping mengurangkan penggunaan sumber asli. Dapat dikatakan penduduk di kawasan kajian masih tidak mengamalkan pengasingan sisa dipunca. Oleh itu disarankan pengasingan sisa dipunca perlu dijadikan satu bentuk pengurusan oleh pihak berkuasa

No full textWaste management, public participation, Sabah Introduction
Full text linkThe increase in world population will cause impact on solid waste. This impact is mostly felt by local authorities. Therefore, cooperation with other stakeholders is essential to ensue that municipal solid waste plan works perfectly. Among the most important element is the involvement of public society. This study aimed to introduce waste recycling in the city. In this study, questionnaire was used to achieve the objectives stated. The study found that residents in the study area are not satisfied on the services provided by the municipal. Furthermore, people in the study area „refuse? to engage actively in the recycling activities. This is because they are not motivated and did not realize the benefits to the environment. Thus, the provision of adequate infrastructure is essential. It can help people to change lifestyles to a more environmentally friendly. Municipal level planning should emphasize methods to increase motivation to carry on recycling.
Keywords: Waste management, public participation, Sabah Introduction
The increase in the world population and industrialisation of more cities mean that managing the waste produced by city inhabitants is a complex issue due not only to the increasing volume of waste through high material consumption but also to the changing characteristics of waste and uncertainty regarding uncontrolled dumping and overflowing landfills. This is especially significant for many cities in the developing world, where populations and economies are rapidly expanding but the infrastructure necessary to manage the ensuing problems remains inadequate.
Over the last century, the world has seen a considerable increase in amounts of waste discharged into the environment. The high generation of solid waste has been identified as a factor contributing to the world environmental problems, and the decrease in suitable landfill sites and scarcity of natural resources is creating greater demand for remanufacturing and reuse. Waste creates environmental consequences such a

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
