Urban and Community Fisheries Programs: Development, Management, and Evaluation
Authors:   Texas Parks and Wildlife Department, Inland Fisheries Division 4200 Smith School Road, Austin, Texas 78744, USA
Published: March 2021

Abstract.-The Texas Parks and Wildlife Department (TPWD) has implemented an urban fishing program with a goal of introducing angling to demographic groups less likely to participate. One challenge is finding marketing methods that effectively identify and recruit target demographic groups to the program. In December 2005, TPWD began year-round biweekly stockings of adult rainbow trout Oncorhynchus mykiss (winter) and channel catfish Ictalurus punctatus (other seasons) in eight major metropolitan area lakes throughout Texas. On-site angler surveys were conducted from December 2005 through November 2006 to determine the number of people fishing at the lakes, the degree to which they had previously participated in fishing, and their ZIP code of residence. We used a Geographic Information System (GIS) supported by the Environmental Systems Research Institute’s (ESRI) ArcGIS® software, including ESRI’s Business Analyst extension, to geocode each respondent’s ZIP code of residence. This allowed us to examine geographic distribution patterns of anglers. The software’s databases of census and marketing survey data allowed us to learn about the characteristics of people residing near the lakes, as well as the probable characteristics of respondents as typified by the characteristics of people residing in their ZIP codes areas. We were able to obtain insight into sensitive demographic information (information that some respondents are reluctant to provide during surveys such as income, race, etc.), evaluate our success in targeting the desired groups, and are using information from the GIS to develop marketing strategies that may help us more effectively reach those groups.
ORTA ÇAĞ İSLÂM COĞRAFYASINDA ENDÜSTRİ ALANINDAKİ TEKNOLOJİK GELİŞMELER
Authors: BİLİNİR Sedat
Published: March 2021

Orta Çağ’da endüstri alanındaki gelişmeler genel olarak eğitim ve toplumların kendi edindiği tecrübeler sonucunda oluşmaktaydı. Bunlara ilaveten ticarî faaliyetler neticesinde tüccarların gittikleri ülkelere kendi teknolojik ürünlerini ve yeniliklerini götürmesi ya da anlatması da bir diğer etkendi. Ayrıca savaşlarda ele geçirilen esirlerden de bir takım silah teknolojisi bilgileri de edinilmekteydi. Yeni bir teknolojiye sahip olmak kolay değildi. Getirilmeye çalışılan her yeni sistemin öğrenilmesi, öğretilmesi, üretilmesi, işlenmesi ve kullanımı gibi durumları söz konusuydu. Yani teknolojiyi almak yetmiyor bir de onun öğretilmesi için bu eğitimi verecek kişilerin getirtilmesi de gerekiyordu. Öğrenilen bu yeni teknoloji iktisadi olarak büyük bir kazancı da beraberinde getirmekteydi. Dolayısıyla teknolojisi ileri olan devletlerin endüstri alanındaki gelişmişliği ve gücü de aynı oranda yükselmekteydi. Orta-Doğu devletleri genelde yenilikleri Çin’den ithal etmekteydi. Orta-Doğu’da kullanılan her yeni teknoloji Avrupa tarafından da yakından takip ediliyordu. Avrupa bu gelişmeleri, gerek İspanya’da Endülüs Emevî Devleti aracılığı ile gerek bölgeye hac vazifesini yerine getirmek için gelen hacılardan gerekse ticarî gelişmeler vasıtasıyla hareket halinde olan tüccarlardan öğrenmekteydi. Bunlara daha sonraları da Haçlı Seferleri eklendi. Endüstri alanındaki yenilikler kapsamında çalışmanın inceleme alanına giren endüstri kolları ağırlıklı olarak; cam, kâğıt, tekstil ve şeker olarak belirlendi. Bunların dışında Ahşap işlemeciliği, gemicilik, madencilik, sabun, gül suyu üretimi ve değirmen endüstrisi hakkında da bilgiler verilmeye çalışılmıştır. Bu gelişmeler doğrultusunda devletlerin elde ettiği gelire baktığımızda, endüstriyel teknoloji için verilen mücadele ve savaşların nedenini daha iyi anlayabiliyoruz. Ayrıca hangi devletin hangi endüstri kolunda daha iyi olduğu, birbirlerine kıyasla üretim kapasiteleri, ithal ve ihracat ürünlerinin neler olduğu gibi bilgiler de çalışmada verilmeye çalışılmıştır.

Authors: Sandy Prilly Mutiara
Published: March 2021

Menurut data WHO pada tahun 2012 menunjukkan bahwa kematian laki-laki secara global adalah sebanyak 52% dan disebabkan oleh penyakit yang tidak menular (NCD). Jika dibandingkan dengan wanita, laki-laki lebih mungkin tutup usia sebelum waktunya (dibawah 70 tahun) akibat NCD di hampir setiap negara. Kemudian, terdapat survey di Asia yang menunjukkan bahwa harapan hidup laki-laki lebih rendah daripada wanita dan merupakan pertanda perlunya peningkatan dalam status kesehatan laki-laki tentang masalah kesehatan yang dapat dicegah dan mendorong deteksi dini serta pengobatan penyakit pada laki-laki. Dengan adanya edukasi, kesadaran mengenai kesehatan diri akan meningkat, dan juga meminimalisir pemahaman yang salah tentang kondisi klinis pada laki-laki. Karena laki-laki pada umumnya menghindari untuk bertemu praktisi kesehatan,lalu memantau dan mengobati sendiri gejala,serta menghilangkan anggapan mempunyai penyakit (walaupun mengalami gejala). Di era teknologi ini, informasi akan lebih mudah didapat jika diakses dalam media digital,seperti: melalui online platform MATE: Men’s Assistant Tracker on Health yang bisa diakses kapanpun dan dimanapun. Aplikasi ini mengedukasi baik secara general maupun spesifik tentang kesehatan laki-laki dan berfokus pada deteksi dini penyakit yang dikombinasikan dengan saran gaya hidup dengan tiga konten utama, yaitu: Daily Tracker, Health Insights, dan Community.

Bekerja adalah kewajiban seorang pria ketika sudah menjadi kepala rumah tangga. Jam kerja yang panjang menyebabkan kondisi badan kelelahan baik secara fisik maupun psikis. Secara nyata akan berpengaruh pada pola hidup yang berdampak pada kualitas kesehatan. Hipertensi merupakan salah satu penyakit yang dipicu akibat kelelahan fisik dan psikis. Obat yang sering digunakan sebagai terapi farmakologi hipertensi adalah kaptopril yang berfungsi sebagai Angiotensin Converting Enzym Inhibitor (ACE I). Disisi lain kaptopril memiliki efek ketoksikan yang tinggi diantaranya gangguan ginjal dan muncul reaksi hipersensitivitas. Sehingga diperlukan inovasi terapi antihipertensi yang fungsi kerjanya sama dengan kaptopril namun tidak memiliki efek samping ketoksikan. Susu fermentasi memiliki senyawa yang yang berpotensi sebagai ACE Inhibitor yang berperan mencegah terbentuknya angiotensin II penghasil aldosteron yang menyebabkan naiknya tekanan darah. Susu fermentasi menjadi sediaan ringan yang dapat dikonsumsi tanpa mengenal batasan usia. Konsumsi susu fermentasi dapat dikombinasikan dengan berbagai menu makanan maupun minuman sehat lainnya. Dalam proses fermentasi bakteri asam laktat akan mengubah kasein beta menjadi senyawa yang berpotensi sebagi ACE I. Namun, menambetapa besar potensi susu fermentasi sebagai antihipertensi, miskonsepsi masyarakat tentang susu perlu diluruskan terlebih dahulu. Oleh karena itu, “SUFERANTIH”  dapat menjadi alternatif terapi non farmakologi untuk hipertensi yang memberikan efek kuratif sekaligus preventif

Perawatan kulit merupakan hal yang sangat diagungkan pada masa sekarang. Tidak hanya wanita namun perawatan kulit kini mulai merambah pada pria. Memiliki kulit yang cerah, putih, bebas jerawat serta bebas dari minyak berlebih merupakan idaman bagi semua kaum. Sebelum dikenalnya perawatan kulit, istilah makeup lebih pertama populer dikarenakan hasil nyata yang terlihat secara jelas dalam waktu yang singkat. Namun dunia makeup yang senantiasa memberikan perbaikan bagi penggunanya dengan cara menutupi atau mempoles bagian tertentu dari tubuh seseorang kini lambat laun mulai ditinggalkan dan berganti dengan perawatan kulit. Hal ini dikarenakan banyaknya bermunculan penelitian dan opini bahwa perawatan kulit lebih menyehatkan dan hasil yang didapat lebih bertahan dalam jangka waktu yang lebih panjang dibanding makeup. Banyaknya variasi produk perawatan kulit yang bermunculan menimbulkan kontroversi dan perilaku konsumtif pada penggunanya. Hal ini juga tidak terlepas dari dampak yang terasa setelah penggunaan perawatan kulit dalam jangka waktu yang lama. Artikel ini dibuat untuk membahas dampak yang timbul dari penggunaan perawatan kulit terhadap skin barrier atau lapisan kulit terluar yang menjaga kulit secara alami dari berbagai macam faktor luar yang dapat merusak kulit.

Published: March 2021

Muitas são as pesquisas a respeito do uso da calculadora em aulas de Matemática. No entanto, são escassas as referentes à análise de livros didáticos. Acreditamos que propostas de atividades com calculadora em situações de investigação, possuem potencial para romper a resistência do não uso desse recurso em aulas de Matemática, fomentando formação continuada aos professores que utilizam. Assim, neste artigo, analisamos, à luz dos ambientes de aprendizagem da Educação Matemática Crítica, atividades com calculadora em uma coleção de livro didático dos anos finais do Ensino Fundamental (6º ao 9º ano) mais distribuída pelo Programa Nacional do Livro Didático 2017. Constatamos que, o ambiente de aprendizagem, cenário para investigação com referência à matemática pura (tipo 2), é o que mais explora o potencial da calculadora, pois, atribui significado ao uso desse recurso em situações de investigação e argumentação matemática. Em relação às atividades analisadas, identificamos um total de 67 atividades com calculadora e observamos a predominância no eixo números e, referência à matemática pura no âmbito de lista de exercício. Atividades relacionadas a cenários para investigação foram escassas. Esses resultados evidenciam limitações para o trabalho didático com a calculadora. No cenário atual, não é suficiente utilizá-la apenas como um recurso de verificação de resultados. É necessário, portanto, que os autores de livros didáticos proponham atividades com calculadora que atribuam significado ao seu uso, contribuindo para o desenvolvimento de habilidades e raciocínio crítico dos estudantes.

According to Islamic Jurisprudence, one of the most important requirements for a sound marriage is the total agreement of the woman under the guardianship of her father or any other mahram relative. In case of none, the ruler or the judge assume to be a guardian or Wali of a woman. A guardian or Wali is responsible for the selection of the righteous person for the woman and assures the protection and welfare of her Rights and interests. He has the authority to reject and refuse the proposal if the suitor did not deem a sound and sincere match. A marriage without a guardian is considered unlawful, as there is no concept of love affairs and courtship without a guardian in Islam. The guardian evaluates the religious, social and economic compatibility of the couple, while on the other hand a woman selects the spouse on physical attraction and romantic notion which vanishes out soon as the real life starts causing potential problems in relationship. That why Islam lays down principle and law of wilayat for a lady to protect her interests and rights and consider to be a shield and safeguard for her welfare in future marital life.

Published: March 2021

The present study examined the constructs of the theory of planned behaviour regarding their predictability of intentions to use a condom among Xhosa-speaking adolescents in Eastern Cape, South Africa, using HIV/AIDS information as a moderator. Design: Quantitative data were collected from 196 adolescents in Eastern Cape, South Africa. A regression analysis was used to test the hypotheses. Results: A regression analysis showed that attitude and perceived behavioural control were significantly related to the intention to use a condom, but subjective norm was not. However, due to the moderating effect of HIV/AIDS information, attitude, perceived behavioural control and subjective norm predicted intention to use a condom. Conclusion: The findings show that HIV/AIDS information plays an important role in increasing the effect of the theory of planned behaviour on intention to use a condom. Thus, more emphasis should be on beliefs about the adverse effects of condom use, the ability to negotiate condom use, and the importance of other significant others in increasing awareness about HIV/AIDS in order to increase intention to use a condom.

Today, acute pancreatitis remains one of the three leading reasons for hospitalization of patients in emergency departments. Despite the fact that the material and technical base of medical institutions is improving every year, it is not always possible to timely and adequately assess the severity of the condition of patients with acute pancreatitis. Underestimation of the severity of the condition can end up sadly for the patient, therefore, patients with severe acute pancreatitis should be identified in the early stages of the disease. To predict the severe course of acute pancreatitis in the early stages of the disease, it is necessary to take into account such risk factors as age, concomitant diseases, body mass index, as well as clinical and laboratory markers of severity: hematocrit, neutrophil-lymphocyte coefficient, distribution of erythrocytes by volume, glucose, urea and data from integral scales. Markers such as respiratory failure and oliguria diagnosed upon admission, as well as the level of lactate dehydrogenase, bicarbonates and acid-base balance of the blood, can also be considered prognostically significant markers of severe course. Early identification of patients with an increased risk of complications and their timely adequate therapy can improve treatment outcomes and reduce mortality rates.

In supply chain, allowing organization to increase revenue since the modern technology enables price changes to be affected at the minimum cost in the supply chain. In supply chain also understandable is managing dynamics of supply chain, both the internal operations, and the relationship. Pricing decisions have different effects on operations in logistics and supply chain. In supply chain management, revenue management is the use of pricing to increase the supply chain surplus, profit generated from the limited supply chain available on the assets utilized. Pricing is a factor that gears up profit in supply chain through an approval to match supply chain demand. Revenue management can be defined as the application of pricing to increase profit, which is produced from a limited supply of supply chain assets. The supply chain limited assets are available for assembly, shipment, storage, while inventory are available in the inner portion of supply chain activities, which are utilized to develop , and make items accessible for production, distribution, wholesalers, selling. In supply chain there may be two forms one is the capacity of the assets that exist for production, transportation, storage, and another is the inventory that exist in order to improve the product
availability, in which multiple customers, revenue management aims to grow profits by selling the assets to the customer, at the right price in supply chain.

“I think we’re all teachers even though we’re students”
Authors: Marciano Joanne
Published: March 2021

Youth of color enrolled in urban public high schools, particularly those students who seek to be the first in their families to graduate from college, frequently encounter barriers to their college readiness and access. This study engaged an analytic approach built with culturally relevant and sustaining theories of education to examine how 10 youth of color enrolled in 12th grade at a Title 1 public high school in New York City provided and/or received support from peers as they navigated such barriers. The study utilized a youth co-researcher methodology to amplify student voices about an issue directly connected to their lives. Two findings emerged across data analysis: (1) students asserted collective notions of academic achievement and (2) challenged what they perceived as inequitable access to resources and opportunities as they supported their peers’ college readiness and access. Taken together these findings provide new insights into possibilities for building from students’ interactions with peers across contexts of curriculum, teaching, and research in urban schools.
Using ensemble reforecasts to generate flood thresholds for improved global flood forecasting
Authors: Zsoter Ervin , Prudhomme Christel , Stephens Elisabeth , Cloke Hannah
Published: March 2021

Global flood forecasting systems rely on definition of flood thresholds for identifying upcoming flood events. Existing methods for flood threshold definition can often be based on reanalysis datasets and single thresholds, used for all forecast lead times, but this leads to inconsistencies between how the extreme flood events are represented in the flood thresholds and the ensemble forecasts.

This paper explores the potential benefits of using river flow ensemble reforecasts to generate flood thresholds that can deliver improved reliability and skill. Using the Copernicus Emergency Management Service’s Global Flood Awareness System, the impact of the dataset and the method used to sample the annual maxima to define flood thresholds, are analysed in terms of threshold magnitude, forecast reliability and skill for different flood severity levels and lead times.

It was found that the variability of the threshold magnitudes, when estimated from the different annual maxima samples, can be extremely large, as can the subsequent impact on forecast skill. It was also found that reanalysis-based thresholds should only be used for the first few days, after which ensemble-reforecast-based thresholds, that vary with forecast lead time and can account for the forecast bias trends, provide more reliable and skilful flood forecasts.

 

 
Breaking down chipping and fragmentation in sediment transport:
the control of material strength
Authors: Bodek Sophie , Jerolmack Douglas J.
Published: March 2021

Abstract. As rocks are transported, they primarily undergo two breakdown mechanisms: chipping and fragmentation. Chipping occurs at relatively low collision energies typical of bed-load transport, and involves shallow cracking; this process rounds river pebbles in a universal manner. Fragmentation involves catastrophic breakup by fracture growth in the bulk – a response that occurs at high collision energies such as rock falls – and produces angular shards. Despite its geophysical significance, the transition from chipping to fragmentation is not well studied. Indeed, most models implicitly assume that impact erosion of pebbles and bedrock is governed by fragmentation rather than chipping. Here we experimentally delineate the boundary between chipping and fragmentation by examining the mass and shape evolution of concrete particles in a rotating drum. Attrition rate should be a function of both impact energy and material strength; here we keep the former constant, while systematically varying the latter. For sufficiently strong particles, chipping occurred and was characterized by the following: daughter products were significantly smaller than the parent; attrition rate was independent of material strength; and particles experienced monotonic rounding toward a spherical shape. As strength decreased, fragmentation became more significant: mass of daughter products became larger and more varied; attrition rate was inversely proportional to material strength; and shape evolution fluctuated and became non monotonic. Our results validate a previously proposed probabilistic model for impact attrition, and indicate that bedrock erosion models predicated on fragmentation failure need to be revisited. We suggest that the shape of natural pebbles may be utilized to deduce the breakdown mechanism, and infer past transport environments.
Position correction in dust storm forecast using LOTOS-EUROS
v2.1: grid distorted data assimilation v1.0
Authors: Jin Jianbing , Segers Arjo , Lin Hai Xiang , Henzing Bas , Wang Xiaohui , Heemink Arnold , Liao Hong
Published: March 2021

Abstract. When calibrating simulations of dust clouds, both the intensity and the position are important. Intensity errors arise mainly from uncertain emission and sedimentation strengths, while position errors are attributed either to imperfect emission timing, or to uncertainties in the transport. Though many studies have been conducted on the calibration or correction of dust simulations, most of these focus on intensity solely, and leave the position errors mainly unchanged. In this paper, a grid distorted data assimilation, which consists of an imaging morphing method and an ensemble-based variational assimilation, is designed for re-aligning a simulated dust plume to correct the position error. This new developed grid distorted data assimilation has been applied to a dust storm event in May 2017 over East Asia. Results have been compared for three configurations: a traditional assimilation that focuses solely on intensity correction, a grid distorted data assimilation that focuses on position correction only, and the hybrid assimilation that combines these two. For the evaluated case, the position misfit in the simulations is shown to be dominant in the results. The traditional emission inversion improves only slightly the dust simulation, while the grid distorted data assimilation effectively improves the dust simulation and forecast. The hybrid assimilation that corrects both position and intensity of the dust load provides the best initial condition for forecast of dust concentrations.

In the last ten years the people on Sebatik Island have experienced water shortages. This happened because the forest which is the source of community water dried up. It is estimated that the drying up of these springs is due to changes in the function of forests as water reserves. This change in forest function occurs as a result of the process of clearing forests for plantations or other development activities. This is why it is necessary to analyze the protected forest cover on Sebatik Island. In this study, analysis of forest cover was carried out based on Landsat satellite imagery. To check the correctness of the analysis results on the satellite image, field checks are carried out. Based on the research results, the forest area on Sebatik Island has an area of ​​2,088.37 ha. The damaged forest is estimated to be 339.97ha, while the protected forest area which is still in good condition has an area of ​​1,748.40 ha.

Dalam proses mengolahnya, khususnya proses pencucian ubi kayu masih dilakukan dengan cara manual dengan mencuci ubi yang telah dikupas satu persatu. Proses ini dinilai tidak efektif karena membutuhkan tenaga manusia lebih dari satu orang, waktu yang lama dan posisi mencuci yang tidak nyaman. Penelitian ini merancang alat dengan pendekatan Antropometri untuk mendapatkan ukuran alat yang ergonomis, mampu mencuci ubi kayu dalam kapasitas besar, nyaman digunakan dan hanya membutuhkan satu orang pekerja. Alat ini memiliki panjang 230 cm, lebar 128 cm dan tinggi 121 cm dengan bahan utama yaitu tabung drum, besi padu 1 ½ inchi, besi padu 1 ¼ inchi, plat UNP 5, plat siku, plat strip, plat aluminium, bearing,belt, pulley, dan motor penggerak. Adapun ukuran antropometri yang dipakai adalah lebar telapak tangan metacarpal, tebal jari telunjuk, lebar telapak tangan sampai ibu jari, diameter genggaman dan segi empat minimum yang dapat dilewati telapak tangan. Alat ini sudah diuji di UMKM Melati dengan kapasitas pencucian 50 kg ubi kayu untuk sekali pencucian  dan dilakukan sebanyak 5 kali dengan waktu 2 menit untuk mendapatkan hasil ubi kayu yang bersih.

The purpose of this paper is to introduce a developed software program called the “Spanish Collocation Tool (SCT)” and its application in related corpus-based studies. The Spanish Collocation Tool (SCT) was designed to assist with the research and analysis of Spanish collocation. The SCT allows searches of collocated elements not limited to words, but also parts of speech and lemmas. Furthermore, it can compare two collocation lists to detect any significant differences between them. In this study, this collocation tool, SCT, and a constructed L3 Taiwanese learners’ written corpus of Spanish called CEATE were combined to create efficient access to results in a systematic approach. Furthermore, by using the SCT, the pedagogical implications of the search results for the development of on-line multimedia material for learning Spanish collocations are discussed in the end.

Optimization of the service implementation for reports of violence against women and children by the Protection Unit for women and children in the Banda Aceh City Police has not been effective due to several motives. The main problem is that a large number of victims are reluctant to report to the police. The reason is that a lot of acts of violence that occur among families are expected to be resolved among families without interventing by the police. The police always appeal to the whole communities if the incident has been repeated, it is hoped that they should immediately report to the police and the time needed to handle or complete cases of violence against women and children is two weeks. The case will be completed if the examination of the perpetrators, victims, and witnesses are not hampered, and as soon as a month, a completed file will be transferred to the prosecutor. Another problem encountered by the police is the unavailability of appropriate room for investigating violence against women and children. It is highly influential in the investigation process to arrest the perpetrators. Besides, the limited budget allocated for this unit also becomes a problem. Lacking public awareness regarding the handling of victims of criminal acts of domestic violence also becomes another problem.

This study aims to gain information concerning the role, obstacles, and efforts of implementing integrated Hajj information and computerization systems at the Office of the Ministry of Religion of North Aceh Regency, Indonesia. Qualitative approaches were employed in collecting the data through observations and interviews. The results revealed that the role of the Office of the Ministry of Religion of North Aceh Regency in implementing the Integrated Hajj Information and Computerization System (SISKOHAT) is still not optimal, based on the report from the society. The problem is the insufficient time to serve the pilgrims who want to register because the group must firstly receive a validation number from BPS-BPIH. The IT facilities (e.g., internet, computers) are also inadequate to support this computerization system program. Besides, the office facilities are not supported or friendly for the majority of elderly pilgrims. Another problem is the lack of sufficient information provided to the pilgrims. Based on these issues, we strongly suggest stakeholders evaluate their services regarding the Hajj information and computerization systems. In terms of information services, service contact numbers (Call Center) should be accommodated to enable the pilgrims to obtain information without wasting much effort and time revisiting the Ministry of Religion office regularly.

The aim of National Education as stated in Law No. 20 of 2003 concerning the National Education System is to give all citizens the right to education, including those with physical, emotional, intellectual, mental, and/or social disabilities entitled to special education. This is also regulated in the Permendiknas R.I. Number 70 of 2009 concerning inclusive education. In this regard, the phenomenon of inclusive education in the Bireuen Regency is still not optimal. The results of this study indicate that the implementation of inclusive education in the Bireuen District encountered numerous barriers. From the aspect of human resources (i.e., teachers), almost all of them are not from an inclusive education background. Most teachers taught in inclusive schools are from the regular honorary teachers. Therefore, special teaching staff with a background in inclusive education are urgently required. Besides, the implementation of inclusive education programs in this region is not well-supported by the stakeholders. From the aspect of facilities and infrastructure, it is not sufficient or inadequate to support the implementation of inclusive education in this district.
