Evidence for the modification of dialect classification of modern spoken Faroese
Authors: Petersen Hjalmar P.
Published: April 2022

In this article, a revised classification of Faroese dialects is presented. Unlike previous classifications, this one takes into account the development and synchronic distribution of unstressed -i’s and -u’s, which has given rise to changes in the inflectional system. In addition to this, it looks both at stressed vowels and aspirated vs. non-aspirated -p, -t, -kafter long vowels. As a result of this evidence, necessary changes to the generally accepted classification system are proposed, with four general dialect areas including transition areas.
Effect of different welding procedures on microstructure and mechanical property of TA15 titanium alloy joint
Authors: Hu Bingzhou , Wang Shaogang , Li Kang
Published: April 2022

TA15 titanium alloy is welded by electron beam welding (EBW) and pulsed Nd:YAG laser beam welding (P-LBW), respectively. Results show that the fusion zone (FZ) is mainly composed of acicular α′ martensite, while the acicular α′ martensite in the FZ of EBW joint is coarser. The quantity of martensite in the FZ of EBW joint is larger and the distribution of martensite is denser. The microstructure of heat-affected zone (HAZ) of the two joints is similar. The HAZ near FZ consists of primary α phase and acicular α′ martensite, and the HAZ near base metal (BM) consists of primary α phase, secondary α phase, and β phase. The hardness in the FZ of EBW joint is slightly higher than that of the P-LBW joint. The tensile strength of both joints is close to that of the BM, but their elongations are decreased to a certain extent. The tensile performance of the EBW joint is slightly better than that of the P-LBW joint. Both joints fail in the BM during stretching. There are many dimples on the fracture surfaces, and the two joints obviously present the characteristics of ductile fracture.
A New Source on the Saljūqs of Rūm and their Persian Chancery: Manuscript 11136 of the Marʿashī Library (Qum)
Authors: Durand-Guédy David
Published: April 2022

At the end of the twentieth century, the Ayatollah Marʿashī Najafī Library (Qum) acquired a fourteenth-century manuscript of munshaʾāt previously held in a private collection. This composite multitext manuscript contains about two hundred letters sent by or to officials of the Rūm Saljūq sultanate in the thirteenth century. The letters include official (sulṭāniyyāt) and private (ikhwāniyyāt) correspondence as well as decrees of nomination (taqrīrāt al-manāṣib). They are all in Persian. This article is a first study of the codicological features, structure, and contents of this manuscript. It suggests a production process that unfolded in several stages over a period of seventy years, from the reign of Ghiyāth al-Dīn Kay-Khusraw II (d. 644/1246) to the second decade of the fourteenth century. The Marʿashī manuscript expands considerably the volume of documents available on Saljūq Anatolia during the beginning of Mongol period. It is poised to become a major source on the political history of the period and will also help to understand the integration of Anatolia into the Persianate sphere.

Photoactive nanomaterials enabled integrated photo-rechargeable batteries
Authors: Rodríguez-Seco Cristina , Wang Yue-Sheng , Zaghib Karim , Ma Dongling
Published: April 2022

The research interest in energy storage systems (e.g. batteries and capacitors) has been increasing over the last years. The rising need for electricity storage and overcoming the intermittent nature of renewable energy sources have been potent drivers of this increase. Solar energy is the most abundant renewable energy source. Thus, the combination of photovoltaic devices with energy storing systems has been pursued as a novel approach in applications such as electric vehicles and smart grids. Among all the possible configurations, the “direct” incorporation of photoactive materials in the storing devices is most attractive because it will enhance efficiency and reduce volume/weight compared to conventional systems comprised two individual devices. By generating and storing electricity in a singular device, integrated photo-rechargeable batteries offer a promising solution by directly storing electricity generated by sunlight during the day and reversibly releasing it at night time. They hold a sizable potential for future commercialization. This review highlights cutting-edge photoactive nanomaterials serving as photoelectrodes in integrated photobatteries. The importance and influence of their structure and morphology and relevant photocatalytic mechanisms will be focal points, being strong influencers of device performance. Different architecture designs and working principles are also included. Finally, challenges and limitations are discussed with the aim of providing an outlook for further improving the performance of integrated devices. We hope this up-to-date, in-depth review will act as a guide and attract more researchers to this new, challenging field, which has a bright application prospect.
Animal Teeth and Mesolithic Society
Authors: Larsson Lars , Douglas Price T.
Published: April 2022

In several graves from the Mesolithic sites of Skateholm, South Sweden, animal teeth were found. Some of these teeth were used as beads in clothing. The strontium isotope analysis of 11 animal teeth is reported and discussed in comparison with human values from burials at the sites and baseline values from South Sweden. Roughly half of the animal teeth are nonlocal and from different places of origin. The beads themselves appear to carry symbolic information that may be related to the physical or social attributes of the wearer. This study involved a detailed investigation of the use-wear around the perforation and its relation to the local and nonlocal origin of the teeth.
Aktuelle Erkenntnisse beim Einsatz von Stabkinematiken
Authors: Pritschow Günter , Diebolder Laetitia , Garber Thomas
Published: April 2022

Stabkinematiken zeichnen sich durch hohe Steifigkeit, kostengünstige Fertigung und hohe Dynamik mittels Minimierung der bewegten Massen aus, so daß sie auch fü r einen breiten Anwenderkreis interessant sind. Wegen der starken Nichtlinearitäten dieser Maschinen ist ihre Auslegung jedoch noch ein schwieriger Prozeß. Die zur Zeit erreichbaren Genauigkeiten von Stabkinematiken sind noch nicht so hoch wie die der konventionellen Maschinen, aber mit Hilfe von neuen Ansätzen ist hier eine deutliche Verbesserung zu erwarten.

Desarrollar proyectos productivos en zonas rurales e ind genas del Estado de Oaxaca: Experiencias estudiantiles
Authors: Damián Simón Javier
Published: April 2022

La atención a las necesidades de la sociedad es una de las finalidades de la formación universitaria. El objetivo de este trabajo es describir las limitantes en el desarrollo de propuestas de proyectos productivos en zonas rurales presentadas por estudiantes de noveno semestre de una carrera de negocios, en la Universidad del Papaloapan, un análisis poco frecuente en el área de estudio. Se encontraron limitantes para identificar ideas de proyectos productivos rurales debido al tipo de formación académica de los estudiantes la cual es distinta al sector rural e indígena, aunado a un escaso interés de autoridades municipales y responsables de organismos públicos relacionados con los proyectos productivos; el poco interés se ve reflejado en la informalidad de los tiempos, incumplimiento de acuerdos y crítica a las propuestas presentadas. Se concluye que la universidad, antes de involucrar a los estudiantes en este tipo de actividades, debe habilitar a los profesores en este tema y establecer vínculos entre los diversos agentes públicos para permitir aportes estudiantiles importantes a las comunidades de origen.
On the Limits of Representation: Ryōan-ji, Ryoanji, Where R = Ryoanji
Authors: Weiss Allen S.
Published: April 2022

Like so many modernist artists, architects, and composers, John Cage was enthralled by the dry garden of the famed Ryōan-ji temple in Kyoto. In his later years he created numerous graphic and musical works inspired by this garden. They are of particular interest insofar as they test the limits of representation, reveal the intricacies of audio mimesis, and speak to the complications of intercultural aesthetic influences.
Anality and Listening (or, Theodor Reik’s Third Ear)
Authors: Kopf James M.
Published: April 2022

In explaining his critical practice, Theodor Reik exhorted his fellow analysts to listen with their third ears. An attempt to discern the meaning of the “third ear” confronts us with a web of associations that point ineluctably to an attempt to decenter the sense of hearing away from the otic cavities. This would point toward more holistic understanding of listening as a bodily phenomenon, on the edge of psychoanalysis and phenomenology—a terrain that Reik, the autobiographical and otobiographical obsessive, frequently traversed over the course of his long career.

My contention is that Reik, consciously or not, drew a link between listening and anality, and, in so doing, opened up to an understanding of bodily attunement with the surrounding world, one that necessarily troubles the interior/exterior binary of what Didier Anzieu, a pioneer in anatomically minded psychoanalysis, calls the “skin-ego.” To explore these questions, this paper will have a fourfold structure. It will begin with an introduction of anality, followed by an explication of Reik’s third ear and an exploration of the oto-anal connection in this light, before finally elaborating on some of the implications of this research.
Auditor Characteristics and Audit Report Lag: Industry Specialization and Long Tenure as Moderating Variables
Authors: Wiedjaja Debby Audrey , Eriandani Rizky
Published: April 2022

Purpose: This study aims to analyze the effect of audit tenure and auditor workload on Audit Report Lag (ARL) and provide empirical evidence of whether the selection of industry-specialized auditors and audit partners with specific workloads can weaken this relationship.Method: This research was conducted using moderated regression analysis. Selection of the research sample using purposive sampling method, from all public listed companies during 2015-2017, 945 firm years were selected.Finding: This study found that audit tenure moderately significantly negatively affects ARL. Besides, this study can also prove that partners with heavy workloads can lead to longer ARL. However, a long partner-client relationship can weaken the workload and ARL relationship because of the auditor's more familiarity and information. Based on these results, the characteristics of auditors affect the timeliness of audit reporting.Novelty: This study enriched the literature by finding out how to deal with audit delay effectively, whereas previous research only focused on identifying ARL causes. This research's implication is expected to provide broader insight to the company regarding several factors that can help companies issue their financial reports on time when the auditors have high workloads and short tenures.
Cryoablation or Drug Therapy for Initial Treatment of Atrial Fibrillation
Authors: Andrade Jason G , Turgeon Ricky D , Macle Laurent , Deyell Marc W
Published: April 2022

AF is a common chronic and progressive disorder. Without treatment, AF will recur in up to 75% of patients within a year of their index diagnosis. Antiarrhythmic drugs (AADs) have been proven to be more effective than placebo at maintaining sinus rhythm and remain the recommended initial therapeutic option for AF. However, the emergence of ‘single-shot’ AF ablation toolsets, which have enabled enhanced procedural standardisation and consistent outcomes with low rates of complications, has led to renewed interest in determining whether first-line catheter ablation may improve outcomes. The recently published EARLY-AF trial evaluated the role of initial cryoballoon ablation versus guideline-directed AAD therapy. Compared to AADs, an initial treatment cryoballoon ablation strategy resulted in greater freedom from atrial tachyarrhythmia, superior reduction in AF burden, greater improvement in quality of life and lower healthcare resource utilisation. These findings are relevant to patients, providers and healthcare systems when considering the initial treatment choice for rhythm-control therapy.

Authors: Neupane Prabesh , Hirachan Anish , Selvaraj Kamaraj
Published: April 2022

Manual thrombosuction during primary angioplasty in an ectatic coronary artery with large thrombus burden carries the risk of incomplete thrombus extraction and thrombus migration. Here, the authors describe a case in which a novel mechanical thrombosuction device with a large lumen and sustained power aspiration enabled the safe and effective complete extraction of a large unfragmented clot. Further studies with such devices are required to shed light on the efficacy and safety of mechanical thrombosuction in coronary interventions.

A bacia hidrográfica do rio Camaquã, localizada na metade sul gaúcha, RS, Brasil, se insere numa área de complexa e relevante geodiversidade, atrelada a aspectos culturais, históricos, turísticos e ambientais típicos regionais. Em virtude de seu potencial geodiverso, evidenciando características geomorfológicas singulares, a área vem sendo alvo de interesse de empreendimentos de diversas tipologias. Esse estudo, realizado em quatro municípios pertencentes ao Alto e Médio rio Camaquã, objetivou a identificação de sítios da geodiversidade. A avaliação quantitativa do potencial turístico e do risco de degradação dos sítios, foi realizada por meio da plataforma Geossit da CPRM. Os resultados apontaram seis sítios da geodiversidade, quatro apresentando relevância turística nacional e dois com relevância turística regional. O risco de degradação foi considerado baixo para o conjunto de sítios identificados, exceto o sítio da Pedra das Torrinhas, classificado com médio risco. A identificação de geopatrimônio ainda não catalogado e, consequentemente, sem proteção assegurada pelos órgãos gestores expõe a necessidade de proposição de estratégias que contribuam para geoconservação da área.

THE GENETIC STRUCTURE OF THEWHITE CYPRINID (TOR TAMBROIDES) POPULATIONS BASEDON COIGENE SEQUENCE ANALYZES
Authors: Wibowo Arif , Husnah Husnah
Published: April 2022

The study analyzed nucleotide sequences from the mitochondrial cytochrome oxidase subunit (COI) gene region (654) to investigate the genetic structure of the white cyprinid (Tor tambroides) among nine populations from the Manna and Semanka Rivers. A total of 36 individuals were collected for this work. Five nucleotides were found to be variable, resulting in 4 haplotypes. Among the nine populations of Melebuy in Semanka River represents the highest level of variability (h = 1.000, π = 0.0015) whereas Kerinjing, Merabung and Kotabumi populations represent the highest level of variability in Manna River (h = 0.667, π = 0.0020). The Batu Aji, Air Sebilo and Kutopadang populations exhibit the lowest level of variability (h = 0.000, π = 0.000). There is an integrated population throughout all sample sites in Manna River. However, the AMOVA analysis provided corroborating evidence for genetic structure obtained from Nei’s genetic diversity statistic and the FST value (0.310), suggested there is genetic divergence among populations of those populations. Of the total genetic diversity, 35% was attributable to inter-population diversity and the remainder (68.92%) to differences within populations. These two approaches produced a picture of genetic structure in Manna and Semanka River. A molecular phylogenetic tree constructed using The Neighbor-joining (NJ) method showed the 4 haplotypes were assigned to two clades associated geographic regions. These results provide basic information for the conservation and sustainable exploitation of this species.

Published: April 2022

This paper provides information on the diets of Chitala lopis in Kampar River, Riau Province based on study conducted from Mei 2009 to November 2010. Fish species were obtained from fishers using modified nets, traps, hooks and lines. Specimens were cold with cool box at the point of collection and transported to the laboratory. A total of 176 fish specimens were inspected and their stomach contents were examined. The month-wise collection and experiments were made to exhibit the seasonal variation in food preferences, and feeding habit of the fish. Frequency of occasion and numerical methods were used in this study. Results of denote that C. lopis fed on juvenile fish, shrimp, plant material, insects, worms, benthos, gravel and unidentified organism. The consumption of shrimp tends to increase due to giant featherback’s size, which relates to wider mouth, energy, location (water depth) and gonad development, also there is an increase of shrimp consumption during dry season. In giant featherback, the percentage of consumed shrimps is associated with sex and season, meanwhile the consumption of small fish and plant material is related to fish’s size, sampling station and maturity index. Giant featherback tends to be more selective consuming certain food’s group while growing.
CPUE TRENDS OF THE INDONESIA’S TUNA LONGLINE FISHERY: LESSONS LEARNED FROM A TRIAL OBSERVER PROGRAM
Authors: Sadiyah Lilis , Dowling Natalie , Prisantoso Budi Iskandar , Andamari Retno , Proctor Craig
Published: April 2022

In an effort to address a shortage of reliable CPUE information, and as a preliminary step to a broader observer program, Indonesia established a Trial Observer Program (TOP) for the industrial tuna long line fishery based at Benoa Fishing Port, Bali, in mid 2005. The objectives of this paper are i) to describe spatial and temporal catch and effort trends from the Indonesian Indian Ocean industrial tuna long line fishery based at Benoa Fishing Port, and ii) to provide an understanding of the fishing strategies used by different companies and of the environmental conditions that may influence catch trends. The observed effort covered areas both north and south of 20°S, with a concentration within 10°-20°S; 105°-120°E which overlaps with the only known spawning grounds of southern bluefin tuna (SBT). This data set showed that SBT comprised the lowest catch proportion, relative to the other three tuna species caught, bigeye tuna (BET), yellowfin tuna (YFT) and albacore (ALB). BET and ALB had been suggested as the main target species for the fishery, but this varied by region. The TOP data set suggests that different tuna fishing companies targeted different species and used different fishing practices, including differences in bait used, areas fished, start time of setting, and the number of hooks between floats (HBF). It is a priority to improve the spatial and temporal coverage of the observer program before the data can be considered to be representative of the fleet, particularly given the high degree of variability in fishing practices between companies.

Published: April 2022

Laguna Segara Anakan mempunyai peran penting sebagai kawasan pengelolaan perikanan udang sebagai daerah asuhan. Penyempitan dan pendangkalan perairan laguna sangat mempengaruhi populasi larva dan juvenil udang. Tujuan penulisan ini adalah untuk mengkaji hubungan perubahan lingkungan terhadap sumberdaya udang. Kandungan oksigen terlarut relatif rendah, kondisi tersebut dalam jangka panjang akan berpengaruh terhadap laju pertumbuhan ikan dan udang, dan akhirnya berdampak langsung terhadap laju rekruitmen udang dan ikan untuk perairan Segara Anakan dan perairan laut sekitar Cilacap. Kelimpahan larva udang dan ikan di perairan laguna ini berkisar antara 87 – 63,451 ind./1000 m3, dan kelimpahan juvenil tersebut berkisar antara 0 – 25,263 ind./1000 m2, dimana selama pengamatan didominasi oleh juvenil udang. Total produksi (ikan dan udang) di Segara Anakan dari tahun ke tahun mengalami penurunan yang signifikan dalam periode tahun 1987-2004. Kondisi tersebut disebabkan luas perairan laguna semakin sempit dan dangkal, serta intensitas penangkapan semakin tinggi. Oleh karena itu, perlu suatu pengelolaan yang menyeluruh terhadap sumber daya laguna agar mampu mengurangi laju penurunan produksinya, yaitu pengelolaan sumberdaya perikanan di laguna Segara Anakan sebagai satu kesatuan ekologi yang utuh.Segara Anakan lagoon have an important role as the shrimp fishery management area in which shrimp species using this area of lagoons as a nursery ground. Refinement and siltation of the lagoon waters greatly affect populations of larvae and juvenile shrimp. The purpose of this paper is to study the relationship of environmental change on shrimp resources. Dissolved oxygen is relatively low, the condition will affect the growth of fish and shrimp in the long time, and ultimately it have a direct impact on the rate of recruitment of shrimp and fish for Segara Anakan waters and coastal waters around Cilacap. Abundance of larval shrimp and fish in this lagoon waters ranged from 87 to 63.451 ind./1000 m3 and the juvenile abundance ranged from 0 to 25.263 ind./1000 m2, where the observations are dominated by the juvenile shrimp. Total production (fish and shrimp) at Segara Anakan from year to year has decreased significantly over the period 1987-2004. The condition is caused by the broad waters of the lagoon is narrow and shallow, and the higher the intensity of fishing. Therefore, the need for a comprehensive management of the lagoon resources in order to reduce the rate of decline in production, the management of fishery resources in the lagoon Segara Anakan as a whole complete ecology.

Akhir-akhir ini, penangkapan berlebih merupakan masalah yang dihadapi dalam pengelolaan perikanan di Indonesia. Kajian pengelolaan perikanan berbasis kapasitas penangkapan merupakan alternatif pendekatan guna mengendalikan faktor-faktor input yang tidak efisien yang digunakan dalam usaha penangkapan. Tujuan penelitian ini adalah mengukur tingkat efisiensi teknis dan pemanfaatan kapasitas alat tangkap pukat cincin di Banda Aceh. Efisiensi penangkapan dan pemanfaatan kapasitas dari pukat cincin yang dikaji dianalisis dengan menggunakan teknik data envelopment analysis (DEA). Data dianalisis menggunakan program linear (linier programming) dengan bantuan software DEAP version 2.1 kemudian pengolahan data dilanjutkan menggunakan program Microsoft Excel version 2007. Hasil penelitian menunjukkan bahwa beberapa armada purse seine di Banda Aceh telah melebihi nilai optimumnya atau telah terjadi kelebihan kapasitas pemanfaatannya. Untuk mencapai nilai optimumnya nelayan pukat cincin perlu mengurangi input yang digunakan. Management of fishing capacity following the method of measurement has become an important issue of excess capacity and overfishing that serious problem faced in Indonesia fisheries management.

Akhir-akhir ini pukat cincin yang dioperasikan menggunakan rumpon laut-dalam (payao) telah menjadi masalah serius pada perikanan tuna. Hal ini karena hasil tangkapan komersialnya lebih menurunkan stok ikan tuna dibandingkan metode lainnya. Tujuan penelitian ini adalah mengevaluasi aktivitas penangkapan dari kapal pukat cincin berdasarkan atas data mendekati waktu sebenarnya (nearly real time) vessel monitoring system dan catatan nelayan yang digunakan untuk mengestimasi jumlah tawur dan produktivitas. Hasil penelitian menyimpulkan bahwa estimasi tawur dari data vessel monitoring system lebih besar dari aktivitas penangkapan yang sebenarnya, alasan perbedaan berkisar 24-43%. Hal ini diakibatkan lebih banyak kegagalan tawur dan tidak ada aktivitas penangkapan karena kondisi cuaca yang buruk. Produktivitas dari lima trip kapal contoh selama tahun 2010 menunjukkan hasil tangkapan berkisar 14-63 ton/trip dengan produktivitas berkisar 0,5-1,73 ton/ tawur, di mana produktivitas terendah terjadi pada trip keenam (bulan Juli sampai Agustus). Hasil tangkapan didominansi oleh ikan cakalang (Katsuwonus pelamis), sedangkan gerombolan ikan cakalang kerapkali bercampur dengan juvenile madidihang (Thunnus albacares) dan juvenile tuna mata besar (Thunnus obesus) yang menghuni lapisan permukaan dan memangsa terutama jenis ikan epipelagis. Keberhasilan perikanan pelagis sebagian besar tergantung pada pengaruhpengaruh jangka pendek, seperti kondisi gelombang besar, arus, terang bulan, dan suhu permukaan laut.Recently, the purse seiners that operated using fish aggregating devices has become a serious problem in tuna fisheries. This commercial catches affected on the declining of tuna stocks compared to other methods. The objective of this study is to evaluate the activity of purse seiners based on nearly real time vessel monitoring system data and records data of the fishermen which was used to estimate haul numbers and productivity. The research concluded that the estimated haul of vessel monitoring system by data is larger than the actual fishing activity, which the difference ranged from 24-43%. It causes more failure haul and no fishing activity due to bad weather conditions. Productivity of 5 trips vessel samples during the year 2010/2011 showed the catch per trip ranges from 14-63 tons and productivity ranges from 0.5-1.73 ton/haul, in which the lowest productivity occurred on the six trip (July until August). The catch was dominated by skipjack (Katsuwonus pelamis) and schools of skipjack often mix with juvenile yellowfin (Thunnus albacares), and big eye (Thunnus obesus). The fish inhabit the surface layer and feed mainly on epipelagic prey. The success of pelagic fishery is largely depend on short

Pemanfaatan sumber daya ikan pelagis kecil di Laut Jawa didominasi oleh armada pukat cincin. Pukat cincin merupakan jenis alat tangkap yang efektif yang dalam kajian stok sumber daya ikan pelagis sering dijadikan sebagai alat tangkap standard. Oleh karena armada pukat cincin memiliki variasi karakteristik teknis, maka untuk menghindari bias perlu dilakukan standardisasi upaya. Standardisasi upaya penangkapan kapal pukat cincin di Laut Jawa periode 2006-2008 dilakukan menggunakan metode analisis komponen utama dari karakteristik teknis; panjang kapal, lebar kapal, dalam kapal, tonase, tenaga penggerak, daya lampu, dimensi jaring, kapasitas palka, dan jumlah ABK. Tiga komponen utama telah dapat menjelaskan lebih dari 60 % total varians yang difungsikan untuk menghitung fishing power masing-masing kapal. Metode analisis komponen utama menghindarkan ketergantungan terhadap satu karakter sehingga memungkinkan untuk melakukan penghitungan nilai fishing power bagi kapal pukat cincin baru yang masuk ke dalam armada pukat cincin. Berdasarkan hasil analisis diperoleh fungsi hasil tangkapan per satuan upaya (CPUE) CPUE = 353.4 * 16.95.Ci dan Fishing Power Indeks (FP) = 1 +(16.59) * (353.4)-1. Ci. Exploitation of small pelagic fish resources in Java Sea was dominated by purse seiners fishery. Purse seine is an effective type of fishing gear, this gear was often used as standard fishing gear for pelagic fish stock assessment. Since purse seiners has a variety of technical characteristics, standardization efforts need to be done to avoid the bias during analysis. Catch effort of purse seiners in Java Sea on the period of 2006-2008 was standardized using principal components analysis method of the boat characteristics, boat length, boat width, boat depth, gross tonnage, engine propulsion, light power, net dimensions, fish hold capacity and total number of crews. Three new major components have explained more than 60% of the total variance which enabled to calculate the fishing power of each boat. Principal components analysis method was used to avoid dependence on a single character to allow the calculation of the value of fishing power for new purse seine fleet. Based on the results obtained by analyzing the function of catch per unit effort formula was CPUE = 353.4 * 16.95.Ci and Fishing Power Index (FP) = 1 + (16.59) * (353.4) -1. Ci.

ABSTRACT: This paperexamined the regional concentration of native fuelwood production in Rio Grande do Norte, Brazil, between 1990-2017. Information on native fuelwood was gathered fromforestry activitiescollected by the Brazilian Institute of Geography and Statistics (IBGE). This studyanalyzed the current situation and the spatial distribution of the state’s fuelwood production by quartiles. The following indicators were used to measure market concentration: Gini Coefficient (G), Comprehensive Concentration Index (CCI), Herfindahl-Hirschman Index (HHI) and Concentration Ratio [CR(k)]. In Rio Grande do Norte, there was a -2.76% annual decrease in the production of native fuelwood, from 5,280 x10³ m³ (1990) to 777 x10³ m³ (2017). Classification of the municipalities by quartile revealed that most municipalities had low fuelwood production. The G inferred a very strong to absolute inequality for the municipalities and a weak to null inequality for the mesoregions.The CCI demonstrated no market concentration in the municipalities and a regional concentration in the mesoregions. The HHI corroborated the CCI by affirming the presence of a competitive market for the municipalities and microregions and a concentrated market in the mesoregions.The CR(k) of the four largest municipalities indicated a moderately low concentration. This study concluded that there is a competitive market structure for native fuelwood inthe state of Rio Grande do Norte.
