Overview of the U.S. East Coast Bottom Longline Shark Fishery, 1994–2003

The U.S. Atlantic coast and Gulf of Mexico commercial shark fisheries have greatly expanded over the last 30 years, yet fishery managers still lack much of the key information required to accurately assess many shark stocks. Fishery observer programs are one tool that can be utilized to acquire this information. The Commercial Shark Fishery Observer Program monitors the U.S. Atlantic coast and Gulf of Mexico commercial bottom longline (BLL) large coastal shark fishery. Data gathered by observers were summarized for the 10-year period, 1994 to 2003. A total of 1,165 BLL sets were observed aboard 96 vessels, with observers spending a total of 1,509 days at sea. Observers recorded data regarding the fishing gear and methods used, species composition, disposition of the catch, mortality rates, catch per unit of effort (sharks per 10,000 hook hours), and bycatch of this fishery. Fishing practices, species composition, and bycatch varied between regions, while catch rates, mortality rates, and catch disposition varied greatly between species.

National Marine Fisheries Service Habitat Conservation Efforts in the Southeastern United States for 1988

Dataq uantifying the area of habitat affected by Federal programs that regulate development in coastal zones of the southeastern United States are provided for 1988. The National Marine Fisheries Service (NMFS) made recommendations on 3,935 proposals requiring Federal permits or licenses to alter wetlands. A survey of 977 of these activities revealed that 359,876 acres of wetlands that support fishery resources under NMFS purview were proposed for some type of alteration or manipulation. Almost 95 percent of this acreage was for impounding andl/or manipulation of water levels in Louisiana marshes. The NMFS did not object to alteration of 173,284 acres and recommended the conservation of 186,592 acres. To offset habitat losses, 1,827 acres of mitigation were recommended by the NMFS or proposed by applicants and/or the Corps of Engineers (COE). From 1981 to 1988 the NMFS has provided in depth analyses on 8,385 projects proposing the alteration of at least 656,377 acres of wetlands. A follow-up survey on the disposition of 339 permits handled by the COE during 1988 revealed that the COE accepted NMFS recommendations on 68 percent. On a permit-by-permit basis, 13 percent of NMFS recommendations were partially accepted, 17 percent were completely rejected, and 2 percent were withdrawn. The permit requests tracked by the NMFS proposed the alteration of 2,674 acres of wetlands. The COE issued permits to alter 847 acres or 32 percent of the amount proposed.

Análise da disposição do material dragado no Canal do Fundão e no Canal do Cunha Rio de Janeiro/RJ.

As operações de dragagem e de disposição final do material dragado são indispensáveis para atender as necessidades de implantação e manutenção das vias de transporte aquaviário. Todavia essas operações, dependendo das dragas e equipamentos utilizados, podem causar danos às comunidades marinhas, alterações na batimetria dentre outras coisas. A circulação de águas na região da Baía da Guanabara compreendida entre a Ilha do Fundão e o continente encontra-se prejudicada, em decorrência das baixas profundidades e estrangulamentos existentes. Entretanto, um projeto de dragagem pode causar vários impactos no meio ambiente. Assim se faz necessário que os organismos e empresas responsáveis pelo meio ambiente e pelo desenvolvimento e execução de projetos de dragagem se preocupem em desenvolver diretrizes e procedimentos para o gerenciamento ambiental de tais projetos. Deste modo, objetivo principal deste trabalho é analisar a disposição do material dragado no Canal do Fundão e Canal do Cunha de acordo com a legislação relacionada as atividades de dragagem. Para isso são: i) identificadas a legislação ambiental existente no Brasil e de organismos internacionais que visam à regulamentação do gerenciamento ambiental das atividades de dragagem; ii) classificados os métodos de destinação do material dragado; e iii) analisado o processo de destinação do material dragado no Canal do Fundão e no canal do Cunha.

Sentimentos morais e o conceito de justiça na filosofia moral de David Hume

Esta dissertação objetiva descrever e analisar criticamente o conceito de justiça no contexto da filosofia moral de David Hume. Com o propósito de fornecer uma explicação completa e consistente de sua teoria da justiça, pretende-se, em primeiro lugar, apresentar a teoria moral sentimentalista de Hume e explicar de que forma sua concepção de justiça se associa com os princípios fundamentais da moralidade. O primeiro capítulo da dissertação consiste, primeiramente, em uma breve exposição do problema do livre-arbítrio e do determinismo e, em segundo lugar, na apresentação da alternativa compatibilista de Hume. Conforme se pretende demonstrar ao longo deste capítulo, a estratégia da solução compatibilista de Hume deve necessariamente envolver a noção de sentimento moral, cujo conceito é central em seu sistema moral. Em seguida, no segundo capítulo, será examinada a teoria moral de Hume, a qual se estrutura em duas hipóteses principais: a tese negativa que contesta a ideia de que o fundamento da moralidade se baseie exclusivamente nas operações da razão (relações de ideias e questões de fato); e a tese positiva que afirma que a fonte da moralidade reside em nossas paixões, sentimentos e afetos de prazer e dor ao contemplarmos caracteres virtuosos e viciosos. O terceiro capítulo visa apresentar a teoria da justiça de Hume, objeto principal desta dissertação. A hipótese central que Hume sugere é que a virtude da justiça não é instintiva ou natural nos seres humanos. Ela é possível unicamente por intermédio de acordos, convenções e artifícios humanos motivados pelo auto-interesse. A tese de Hume é exatamente que a origem da justiça, enquanto uma convenção social, só pode ser explicada com base em dois fatores: a atuação dos sentimentos de nossa disposição interna e a circunstância externa caracterizada pela escassez relativa de bens materiais. Finalmente, o último capítulo desta dissertação visa discutir a teoria política de Hume com o propósito de complementar sua teoria da justiça. Hume defende que a justificação da instituição da autoridade soberana e dos deveres civis se funda nos mesmos princípios da convenção de justiça: eles também são artifícios criados exclusivamente para servir ao nosso próprio interesse.

Life history and behaviour of Indian prawns

Studies on life history and behaviour of prawns form an essential background for the understanding of the disposition of their fisheries and for the formulation of effective methods of exploitation and measures of conservation.

Inland prawn fisheries of India and their development

The lack of adequate knowledge of the capture fisheries resources has been pointed out and the necessity for an organised survey of the resources and research to formulate measures for their proper management emphasised. The existing methods of prawn farming in the country have been described and the need for research for maximising yields from culture fisheries of prawn has been highlighted. Measures for immediate development of prawn fisheries of the country have also been discussed.

Psychometric evaluation and experimental validation of the statistics anxiety rating scale.

The Statistics Anxiety Rating Scale (STARS) was adapted into German to examine its psychometric properties (n = 400). Two validation studies (n = 66, n = 96) were conducted to examine its criterion-related validity. The psychometric properties of the questionnaire were very similar to those previously reported for the original English version in various countries and other language versions. Confirmatory factor analysis indicated 2 second-order factors: One was more closely related to anxiety and the other was more closely related to negative attitudes toward statistics. Predictive validity of the STARS was shown both in an experimental exam-like situation in the laboratory and during a real examination situation. Taken together, the findings indicate that statistics anxiety as assessed by the STARS is a useful construct that is more than just an expression of a more general disposition to anxiety.

Statistics anxiety, state anxiety during an examination, and academic achievement.

BACKGROUND: A large proportion of students identify statistics courses as the most anxiety-inducing courses in their curriculum. Many students feel impaired by feelings of state anxiety in the examination and therefore probably show lower achievements. AIMS: The study investigates how statistics anxiety, attitudes (e.g., interest, mathematical self-concept) and trait anxiety, as a general disposition to anxiety, influence experiences of anxiety as well as achievement in an examination. SAMPLE: Participants were 284 undergraduate psychology students, 225 females and 59 males. METHODS: Two weeks prior to the examination, participants completed a demographic questionnaire and measures of the STARS, the STAI, self-concept in mathematics, and interest in statistics. At the beginning of the statistics examination, students assessed their present state anxiety by the KUSTA scale. After 25 min, all examination participants gave another assessment of their anxiety at that moment. Students' examination scores were recorded. Structural equation modelling techniques were used to test relationships between the variables in a multivariate context. RESULTS: Statistics anxiety was the only variable related to state anxiety in the examination. Via state anxiety experienced before and during the examination, statistics anxiety had a negative influence on achievement. However, statistics anxiety also had a direct positive influence on achievement. This result may be explained by students' motivational goals in the specific educational setting. CONCLUSIONS: The results provide insight into the relationship between students' attitudes, dispositions, experiences of anxiety in the examination, and academic achievement, and give recommendations to instructors on how to support students prior to and in the examination.

海拉尔盆地贝尔凹陷基岩潜山特征及储层预测

The lithology of the buried hill of Triassic Budate group in Beier depression is epimetamorphic clastic rock and volcanic clastic rock stratum. Recently the favorable hydrocarbon show was discovered in buried hill of base rock, and large-duty industrial oil stream was obtained in some wells in Beier depression. Based on the information of seismos and wells, the tectonic framework, tectonic deformation times and faulted system of the Beier depression are comprehensively studied, then configuration, evolutional history, genetic type and distributed regularity of buried hill are defined. According to observing description and analysis of core sample, well logging and interpretive result of FMI, the lithological component, diagenetic type and diagenetic sequence of buried hill reservoir are confirmed, then reservoir space system of buried hill is distinguished, and vegetal feature, genetic mechanism and distributed regularity of buried hill fissure are researched, at the same time the quantitative relationship is build up between core fissures and fissures interpreted by FMI. After that fundamental supervisory action of fault is defined to the vegetal degree of fissure, and the fissure beneficial places are forecasted using fractal theory and approach. At last the beneficial areas of Budate group reservoir are forecasted by reservoir appraisal parameters optimization such as multivariate gradually regression analysis et. al. and reservoir comprehensive appraisal method such as weighing analyze and clustering procedure et. al. which can provide foundation for the next exploratory disposition. Such production and knowledge are obtained in this text as those: 1. Four structural layers and two faulting systems are developed, and four structural layers are carved up by three bed succession boundary surfaces which creates three tectonic distortional times homology. Three types of buried hill are divided, they are ancient physiognomy buried hill, epigenetic buried hill, and contemporaneous buried hill. 2. Reservoir space of Budate buried hill is mainly secondary pore space and fissure, which distributes near the unconformity and/or inside buried hill in sections. The buried hill reservoir experienced multi-type and multi-stage diagenetic reconstruction, which led to the original porosity disappeared, and multi secondary porosity was created by dissolution, superficial clastation and cataclasis et. al. in diagenetic stage, which including middle crystal pore, inter crystal pore, moldic pore, inter particle emposieu, corrosion pore space and fissure et. al. which improved distinctly reservoir capability of buried hill. 3. The inner reservoir of buried hill in Beier depression is not stratigraphic bedded construction, but is fissure developing place formed by inner fault and broken lithogenetic belt. The fissures in inner reservoir of buried hill are developed unequally with many fissure types, which mainly are high angle fissure and dictyonal fissures and its developing degree and distribution is chiefly controlled by faulting. 4. The results of reservoir comprehensive evaluate and reservoir predicting indicates that advantageous areas of reservoir of buried hill chiefly distributes in Sudeerte, Beixi and Huoduomoer, which comprehensive evaluate mainly Ⅱand Ⅲ type reservoir. The clues and results of this text have directive significance for understanding the hydrocarbon reservoir condition of buried hill in Beier depression, for studying hydrocarbon accumulated mechanism and distributed regularity, and for guiding oil and gas exploration. The results of this text also can enrich and improve nonmarine hydrocarbon accumulated theory.

松辽盆地南部大情字井地区CO2埋存体地质格架及储层建模

Increasing attentions have been paid to the subsurface geological storage for CO2 in view of the huge storage capacity of subsurface reservoirs. The basic requirement for subsurface CO2 storage is that the CO2 should be sequestrated as supercritical fluids (physical trapping), which may also interact with ambient reservoir rocks and formation waters, forming new minerals (chemical trapping). In order to the effective, durable and safe storage for CO2, enough storage space and stable sealing caprock with strong sealing capacity are necessitated, in an appropriate geological framework. Up till now, hydrocarbon reservoirs are to the most valid and appropriate CO2 storage container, which is well proven as the favorable compartment with huge storage capacity and sealing condition. The thesis focuses on two principal issues related to the storage and sealing capacity of storage compartment for the Qingshankou and Yaojia formations in the Daqingzijing block, Southern Songliao Basin, which was selected as the pilot well site for CO2-EOR storage. In the operation area, three facies, including deltaic plain, deltaic front and subdeep-deep lake facies associations, are recognized, in which 11 subfacies such as subaqueous distributary channel, river- mouth bar, interdistributary bay, sheet sandbody, crevasse splay and overflooding plain are further identified. These subfacies are the basic genetic units in the reservoir and sealing rocks. These facies further comprise the retrogradational and progradational depositional cycles, which were formed base- level rise and fall, respectively. During the regressive or lake lowstand stage, various sands including some turbidites and fans occurred mostly at the bottom of the hinged slope. During the progradation stage, these sands became smaller in size and episodically stepped backwards upon the slope, with greatly expanded and deeped lake. However, most of Cretaceous strata in the study area, localized in the basin centre under this stage, are mainly composed of grey or grizzly siltstones and grey or dark grey mudstones intercalated with minor fine sandstones and purple mudstones. On the base of borehole and core data, these siltstones are widespread, thin from 10 to 50 m thick, good grain sorting, and have relative mature sedimentary structures with graded bedding and cross- lamination or crossbeds such as ripples, which reflect strong hydrodynamic causes. Due to late diagenesis, pores are not widespread in the reservoirs, especially the first member of Qingshankou formation. There are two types of pores: primary pore and secondary cores. The primary pores include intergranular pores and micropores, and the secondary pores include emposieus and fracture pores. Throat channels related to pores is also small and the radius of throat in the first, second and third member of Qingshankou formation is only 0.757 μm, 0.802 μm and 0.631 μm respectively. In addition, based on analyzing the probability plot according to frequency of occurrence of porosity and permeability, they appear single- peaked distribution, which reflects strong hetero- geneity. All these facts indicate that the conditions of physical property of reservoirs are not better. One reason may be provided to interpret this question is that physical property of reservoirs in the study area is strong controlled by the depositional microfacies. From the statistics, the average porosity and permeability of microfacies such as subaqueous distributary channel, channel mouth bar, turbidites, is more than 9 percent and 1md respectively. On the contrary, the average porosity and permeability of microfacies including sand sheet, flagstone and crevasse splay are less than 9 percent and 0.2md respectively. Basically, different hydrodynamic environment under different microfacies can decide different physical property. According to the reservoir models of the first member of Qingshankou formation in the No. well Hei47 block, the character of sedimentary according to the facies models is accord to regional disposition evolution. Meantime, the parameter models of physical property of reservoir indicate that low porosity and low permeability reservoirs widespread widely in the study area, but the sand reservoirs located in the channels are better than other places and they are the main sand reservoirs. The distribution and sealing ability of fault- fractures and caprock are the key aspects to evaluate the stable conditions of compartments to store CO2 in the study area. Based on the core observation, the fractures widespread in the study area, especially around the wells, and most of them are located in the first and second member of Qingshankou formation, almost very few in the third member of Qingshankou formation and Yaojia formation instead. In addition, analyzing the sealing ability of eleven faults in the three-dimensional area in the study area demonstrates that most of faults have strong sealing ability, especially in the No. well Hei56 and Qing90-27. To some extent, the sealing ability of faults in the No. well Hei49, Qing4-6 and Qing84-29 are worse than others. Besides, the deposition environment of most of formations in the study area belongs to moderately deep and deep lake facies, which undoubtedly take advantage to caprocks composed of mudstones widespread and large scale under this deposition environment. In the study area, these mudstones distribute widely in the third member of Qingshankou formation, Yaojia and Nenjiang formation. The effective thickness of mudstone is nearly ~550m on an average with few or simple faults and fractures. In addition, there are many reservoir beds with widely- developed insulated interbeds consist of mudstones or silty mudstone, which can be the valid barrier to CO2 upper movement or leakage through diffusion, dispersion and convection. Above all, the closed thick mud caprock with underdeveloped fractures and reservoir beds can be taken regard as the favorable caprocks to provide stable conditions to avoid CO2 leakage.

恋情嫉妒倾向及其影响因素和影响作用的研究_恋情嫉妒倾向与自尊、社会比较偏好及嫉妒情绪反应之间的关系

As a well-related concept with close relationship, dispositional romantic jealousy (worrying about the romantic relationship will decrease or be threatened because of the rival) is accepted more and more attention. As the first system study on romantic jealousy under Chinese culture, this study use the combinative methods of questionnaire survey and provided situation-imagine design to study the dispositional romantic jealousy and get some conclusions. 1、The structure of the dispositional romantic jealousy in Chinese undergraduate students consist of three factors: suspicion , exclusivity and dependency . The scale of romantic jealousy has good reliability and validity. 2、The dispositional romantic jealousy can well predict the love attitudes and love experiences. The three factors respectively have different relationship with the love attitudes and love experiences. 3、Comparing with the high self-esteem samples, low self-esteem (include explicit self-esteem, and special implicit self-esteem) samples express more dispositional romantic jealousy among some of the three aspects: suspicion , exclusivity and dependency. 4、Those who get high scores on Scale of Social Comparison Orientation have far more remarkable dispositional romantic jealousy than those who get low scores, the difference exits in three factors: suspicion , exclusivity and dependency. 5、The result of SEM tells us that explicit self-esteem and special implicit self-esteem can negetivly predict some of the three factors of the dispositional romantic jealousy. And special implicit self-esteem also can predict the jealous emotional reaction .Social comparison orientation can predict all three factors of the disposition. And all three factors can positively predict jealous emotional reaction. These findings help us identify the structure of the dispositional romantic jealousy and know more about the influence factors of dispositional romantic jealousy. So we can provide an academic reference on the prevention and intervention of the conflicts among marriage and love relationships.

共情、共情唤醒机制及共情结果的关系

Empathy was defined as affective experience isomorphic to another person’s affective experience elicited by the person’s affective state in this research. By constructing questionnaires and situational measurement approaches, the relationship among empathy, perspective-taking, imagination, empathic concern, distress, and interconnectedness and helping was analyzed. Perspective-taking and imagination were regarded as arousal mechanisms of empathy. Empathic concern and distress were reactive outcomes of empathy. Interpersonal outcomes of empathy were discussed in this research were empathic interconnectedness and helping. The results showed that perspective-taking had significant positive influence on empathic concern. Empathy partly mediated the effects of perspective-taking on empathic concern. Influence of imagination on empathic distress was partly mediated by empathy also. Perspective-taking had significant negative influence on empathic distress. Empathy had direct effects on its reactive outcomes, and indirect effects on its interpersonal outcomes mediated totally by empathic concern. Classification analysis according to the relationship among empathy, its arousal mechanisms, and reactive outcomes of empathy showed that disposition of empathic reactivity could be divided into 4 styles: general high empathy (22.5%), general low empathy (25.7%), empathic concern (24.4%) and empathic distress (27.3%). 4 styles were different in interpersonal acuity and mental health. It was suggested that adaptive function of 4 styles was different. And the styles of disposition of empathic reactivity significantly predicted situational empathy and its intrapersonal and interpersonal outcomes.
