The Impact of Controlling for Risk on the Value Relevance of Earnings: Evidence from the U.S.
Authors: Ortega Xiaoli
Published: August 2017

Prior research documents the relatively low explanatory power of the earnings-return association in traditional models that regress returns on levels and changes in earnings. However, these studies fail to consider the impact of variation in discount rates, or risk, as a possible cause of the low explanatory power. In this study, I investigate the impact of controlling for risk on the explanatory power of the earnings-return relation. I begin by estimating two related regression models of annual returns on earnings and changes in earnings drawn from prior research. Then, to examine whether controlling for risk affects the explanatory power of the regressions, I sort observations into portfolios formed on various risk proxies, including market beta, firm size, earnings/price ratio, two implied cost of equity capital proxies, and the combination of beta and firm size. I document higher average adjusted R2s that suggest a 30% increase in explanatory power, and larger average coefficient estimates of earnings, when I estimate the return-earnings regressions within risk portfolios than those of the Easton and Harris and Easton and Pae models. These findings suggest that controlling for cross-sectional variation in risk, a denominator effect, improves the explanatory power of the model.
Hotel Industry Regulations and Cross-Border Franchising: The Case of Saudi Arabia
Authors: Aleidan Megbel Mishary
Published: August 2017

Saudi Arabia has formulated and enforced a new tourism law to develop its tourism sector with special emphasis to open more international activities in the hotel industry. The main objective of this study was to determine the influence of new regulations of hotel industries in Saudi Arabia on the decision making process of the hotel companies in relation to international franchising. Qualitative research design was used to investigate the connection between new regulations of hotel industry in Saudi Arabia and its cross-border franchising activities. Data was retrieved from two primary sources: governmental agencies and, the hotel and leisure companies involved in franchising. The main sectors covered were the investment in tourism lands, establishment of tourism based associations, and replacement of foreigners, price and classification. Data was generated through twelve in-depth interviews with the representatives of the sample companies, from April to September 2016. The primary data generated during interviews was complemented by data from industrial publications and the annual reports to know about the current status of Saudi hotel industry and the activities of the sample companies. Findings confirmed that the regulatory reforms of a hotel industry, by following new hotel-based regulations, added new vigor to hotel based industry and enhanced its international profile. The new tourism law authorized the Saudi Commission for Tourism and Heritage (SCTH) to identify and propose new lands for tourism investment, which may increase its importance among the global hotels’ franchisors.

An intervention study was performed as a class (50 min for 136 junior high school students aged 13-14 years old) using a picture leaflet for junior high school students. The leaflet shows a detailed model day for “morning-typed student” versus “evening-typed one” based on several scientific evidences so far. An integrated questionnaire was administrated just before the intervention class and also one month after the class and the effects of class was evaluated. The questionnaire included the Diurnal Type Scale (DTS) which Torsvall and Ǻkerstedt (1980) constructed, and questions on sleep habits, mental health and breakfast contents. Among the students who occupied 75% as the morning- and medium typed populations before the intervention, students who increased the number of dishes at breakfast after the intervention class did not significantly shift their DTS scores (p=0.200), while students who did not change the number shifted their DTS scores to more evening-typed (p=0.012). Among ones who occupied 25% as evening-typed, students who increased the number of dishes significantly shifted their DTS to morning-typed (p=0.026), while ones who did not change the number did not change their DTS (p=0.893). In the whole, although the students experienced the intervention class, there were no significant effects to shift their diurnal rhythm into morning-typed direction, because the month after the intervention is the winter holidays (December-January). The intervention study may be effective for students to prevent the shift of their diurnal rhythm into “evening-typed”, even though the teacher of the intervention class has no previous knowledge on sleep sciences at all and study the leaflet for only 2 or 3 hours just before the class.

Published: August 2017

Exams are a part of an important system which shows teachers and students the level of how much the topics have been covered. However, the level of suitability of using the same assessment tool for every subject is quite important when preparing these exams. Therefore, the importance of mathematics examinations has been addressed in this study. In this context, the difficulties encountered by teachers while preparing mathematics examinations and the issues regarding this were intended to be identified. A qualitative research method has been used in the research. The data has been collected by the interviews conducted with the school administrators and by the interview forms filled in by teachers. In consequence, it has been revealed that the schools and teachers have not been inspected for years and the basic deficiencies due to the primary education lead to problems in the mathematics exams performed associated with the secondary education with the arrangement of the regulation on passing exams every year.

Published: August 2017

Jednou z možností, jak lze podporovat školy v jejich směřování k inkluzivnímu vzdělávání, je posilování odborného potenciálu škol skrze ustavování nových, poradensky orientovaných funkcí pedagogických pracovníků či dalších specialistů. Mezi tyto specialisty bezesporu patří i školní psychologové a naším záměrem v tomto textu je přiblížit, jak inkluzivní směřování škol proměňuje náhled školních psychologů na svou práci. Na základě empirických dat (vícečetná případová studie) ze dvou základních proinkluzivních škol popíšeme, jak školní psychologové reflektují svou práci, jak vnímají (staro)nová očekávání učitelů i vedení svých škol a jak nahlížejí vlastní roli v podpoře školy při zvládání zvyšující se diverzity žáků.
Morální distres školních psychologů
Authors: Mareš Jiří
Published: August 2017

Přehledová studie shrnuje současné domácí i zahraniční poznatky o tom, co prožívá školní psycholog ve vztahové síti školy a jak reaguje na situace, kdy je vystaven sociálním tlakům ze strany vedení školy nebo učitelského sboru či nadřízených školských orgánů. Na psychologa bývá občas vyvíjen nátlak, aby ve „vyšším zájmu“ souhlasil s rozhodnutími, která se týkají žáků, kolegů, rodičů i školy, i když takové rozhodnutí není z etického hlediska v pořádku. Přehledová studie věnovaná tomuto tématu má pět částí. První část prezentuje názory odborníků a výsledky dílčích výzkumných sond o etických problémech, s nimiž se setkávají školní psychologové v České republice. Druhá část prezentuje výsledky výzkumů těch etických problémů a etických dilemat, s nimiž se potýkají školní psychologové v USA, Kanadě a ve vybraných evropských zemích. Ve třetí části je charakterizován důležitý pojem této studie – morální distres. Čtvrtá část studie popisuje kvalitativní, kvantitativní a smíšené diagnostické přístupy ke zkoumání eticky náročných situací, i zvláštnosti školních psychologů, kteří se v těchto situacích musí rozhodovat. Pátá část shrnuje doporučení o tom, jak morálnímu distresu u školních psychologů předcházet, a pokud už se distres vyskytne, jak v  takových případech cíleně intervenovat, aby se jeho negativní dopady snížily.
Swedish School Development and Inclusive Learning Environments: A Single Case Study
Authors: Öhman Malin
Published: August 2017

The aim of the study was to explore teachers’ and school support team’s experiences and description of their own, and their own school’s process towards developing more inclusive learning environments. The results of the study reveal that the school has undergone significant development. Teachers report that there has been a change of language usage and value. They also describe how they have moved from ideology to change of practice in the classroom. At the same time, the picture that emerges is that of an uneven spreading effect between different teacher teams, and even more so between the school support team and the rest of the school. The school support team expressed an ambition to work with health promotion and prevention programs. However, the long-term tradition in which the work often is characterized by an individual focus based on the shortcomings of particular students seems hard to change.

As cooperativas de crédito atuam similarmente a outras instituições financeiras, captando depósitos, oferecendo crédito e prestando serviços diversos de pagamentos e compensação de documentos, entretanto, possuem características próprias, se distinguindo assim, dos bancos convencionais. Por meio da aplicação de questionário a 347 usuários das três cooperativas do município, obteve-se um perfil e identificou-se os fatores socioeconômicos e comportamentais de acesso ao sistema cooperativista. A partir da análise de regressão logística, pôde-se conhecer os fatores que mais determinam o acesso às cooperativas de crédito do município de Teófilo Otoni, que são: rendimento compreendido entre um e cinco salários mínimos; baixa quantidade de serviços utilizados; as cooperativas são a primeira opção em utilizar os serviços bancários; as cooperativas são consideradas melhores que os bancos; indicação da cooperativa; localização da cooperativa.

Published: August 2017

O presente artigo analisa as práticas da autogestão nas cooperativas pertencentes à Rede Cata-Vida e à Central de Reciclagem de Sorocaba. A metodologia de coleta de dados envolveu a análise documental, a observação participante direta do trabalho e a realização de entrevistas com cooperados, parceiros e fundadores das cooperativas. O estudo que analisou e comparou as diferentes culturas organizacionais dessas organizações revela que ambas estão preocupadas em educar os cooperados, visando à conscientização para a prática da autogestão das cooperativas. Porém, tais esforços de emancipação dos cooperados sofrem pressões do contexto social e econômico em que estão inseridos, enfrentando barreiras como a precária formação escolar dos cooperados, limitando muitas vezes a autogestão às decisões operacionais, enquanto as decisões estratégicas permanecem a cargo dos agentes externos.

Published: August 2017

O objetivo da presente pesquisa foi analisar o nível de evidenciação de informações representativas de responsabilidade organizacional – econômicas e financeiras, sociais e ambientais – das Entidades de Interesse Social, tidas como organizações da sociedade civil a partir da Lei Federal nº 13.019/14. A pesquisa foi feita por meio da criação de indicadores representativos de informações de cada uma das categorias. Depois, pela observação não participante, procedeu-se análise de conteúdo para identificar a presença ou não dos indicadores nas páginas eletrônicas de internet de duas Entidades de Interesse Social: a LBV e a AACD. Na sequência, atribuiu-se peso um para o indicador evidenciado e zero para o não evidenciação, o que resultou em índices de evidenciação por categoria e geral de responsabilidade organizacional para cada uma das entidades. Os resultados demonstram que a LBV evidencia mais do que a AACD em todas as categorias, caracterizando prestação de contas eficiente para seus públicos de interesse. Fator esse que pode representar retorno em forma de maior legitimidade organizacional.

Published: August 2017

Entre as atividades que permeiam o processo educacional, a avaliação se constitui como uma área de íntima associação com o processo de ensino-aprendizagem. Discutir a avaliação educacional remete à compreensão do papel que as escolas, inclusive as de ensino superior, exercem sobre a vida das pessoas. O papel crítico que deve ler levado em conta na formação dos alunos, de que resulta uma qualidade política, passa também pelo processo de avaliação a que é submetido. Isso não retira a importância da qualidade formal, ou seja, o conhecimento técnico que deve ser almejado no processo ensino-aprendizagem. Nesse sentido, o presente artigo procurou analisar o processo de avaliação nas disciplinas do curso de Administração de uma IES, nas perspectivas docente e discente. Para tal, a pesquisa aplicou 20 questionários a docentes e 70 entrevistas a discentes da IES investigada. Os dados foram tratados quantitativamente. Os resultados indicaram que, apesar de algumas incongruências constatadas no processo ensino-aprendizagem, a IES, por meio dos seus docentes, desenvolve um ensino que se aproxima dos ditames preconizados pelos teóricos em pedagogia na formação de administradores.

O processo de expatriação na estratégia organizacional
Authors: Gallon Shalimar , Antunes Elaine Di Diego
Published: August 2017

A interação entre as multinacionais, a matriz e as práticas de Gestão de Recursos Humanos (GRH) tem sido um desafio para as organizações, pois, embora os estudos na área de internacionalização de GRH com ênfase na expatriação e na estratégia organizacional tenha aumentado, estes não têm abordado fatores estratégicos fundamentais para a implementação da estratégia organizacional. Apesar de existirem modelos de internacionalização, poucos são os que consideram a expatriação com um processo importante na condução na internacionalização da empresa. A expatriação está relacionada com o negócio da empresa e não somente com a GRH. Dependendo dos objetivos da empresa, o conceito de expatriado pode ser entendido de diversas maneiras. Os diversos conceitos das missões internacionais se caracterizam em função do trabalho a ser desempenhado, da duração e da quantidade de viagens realizadas na missão. Essa diversidade surge como uma demanda para englobar um processo que vem tomando uma dimensão mais ampla em função da sua importância para as estratégias internacionais das empresas. Para tanto, esse estudo teórico busca abordar a expatriação mais do que uma prática de GRH, sendo, portanto, um processo ligado à estratégia internacional da empresa.
Políticas públicas e a ascensão de uma nova classe média como instrumento de reprodução do capitalismo (uma visão crítica)
Authors: Gomes Eduardo Biacchi , Jaboniski André Leonardo
Published: August 2017

Presente o debate sobre a ascensão social da “ralé” estrutural ao estrato dos batalhadores brasileiros. Tais mudanças sociais são decorrentes de políticas públicas redistributivas adotadas pelo governo nos últimos anos e que não condizem com uma visão economicista de ascensão de uma nova classe média. Pelas recentes alterações das condições de vida de uma parcela da sociedade brasileira, com a sua inclusão no mercado de bens de consumo; indaga-se se estaríamos diante de uma nova classe média ou  diante de mais uma reconstrução do capitalismo e seu discurso sedutor para induzir os batalhadores brasileiros a se submeterem às novas condições de trabalho ? Entenda-se referidas condições de trabalho como: flexibilizadas precarizadas bem como, de indução ao fetichismo de consumo enquanto formador de um espírito artificial de felicidade e sequestrador da subjetividade destes indivíduos.Assim, importante se torna a discussão acerca das condições de vida deste novo grupo social, bem como dos aspectos que a diferenciam da classe social e sua consciência de classe, dentro do contexto laboral.
Estado social e administração pública de garantia
Authors: Bitencourt Neto Eurico
Published: August 2017

As transformações em curso no modelo de Estado moderno, como o abalo da clássica noção de soberania, a fragmentação interna e externa do poder e o reforço de instrumentos de cooperação entre entes públicos e privados, têm provocado importantes mudanças nos modos de atuação da Administração Pública. Tal fenômeno tem provocado uma gradativa substituição de Administração Pública prestadora por uma Administração reguladora ou de garantia. Este artigo demonstra a compatibilidade da Administração de garantia com o princípio da socialidade consagrado em diversas Constituições contemporâneas, como a brasileira de 1988. Mais do que isso, aponta a necessidade de se ter em conta que qualquer meio de atuação da Administração Pública deve se enquadrar nas balizas do Estado social ainda vigente.
Crítica ao chamado corte metodológico e a necessidade de uma ciência prática no direito tributário
Authors: Maria Ferreira Neto Arthur
Published: August 2017

Pretende-se neste estudo analisar a concepção de ciência tributária prevalecente no direito brasileiro, de modo a analisar, criticamente, os seus pressupostos teóricos, buscando, com isso, demonstrar a insuficiência do modelo teórico formalista e normativista dominante, principalmente em razão do seu reducionismo explicativo. Como alternativa, propõe-se a adoção de concepção mais abrangente e complexa de ciência jurídica – pautada na concepção de ciência prática (scientia practica) desenvolvida pela tradição filosófica aristotélico-tomista – a qual teria pretensões de, não apenas descrever o direito positivo, mas também de explicar, esclarecer e tornar mais inteligível as diferentes dimensões do fenômeno tributário, não apenas no que se refere ao momento da positivação das normas jurídicas, mas também no que se refere aos momentos anteriores e posteriores a esse processo, ou seja, que também se dedique a analisar os motivos, causas, efeitos, consequências e fins das normas de tributação.

The neural crest is a dynamic progenitor cell population that arises at the border of neural and non-neural ectoderm. The inductive roles of FGF, Wnt, and BMP at the neural plate border are well established, but the signals required for subsequent neural crest development remain poorly characterized. Here, we conducted a screen in primary zebrafish embryo cultures for chemicals that disrupt neural crest development, as read out by crestin:EGFP expression. We found that the natural product caffeic acid phenethyl ester (CAPE) disrupts neural crest gene expression, migration, and melanocytic differentiation by reducing Sox10 activity. CAPE inhibits FGF-stimulated PI3K/Akt signaling, and neural crest defects in CAPE-treated embryos are suppressed by constitutively active Akt1. Inhibition of Akt activity by constitutively active PTEN similarly decreases crestin expression and Sox10 activity. Our study has identified Akt as a novel intracellular pathway required for neural crest differentiation.
Notes on juvenile sailfish, Istiophorus platypterus (Shaw and Nodder, 1791), caught in the Mexican Pacific
Authors: Vidauri-Soteto AL , Macías-Zamora R , Santana-Hernández H
Published: August 2017

The purpose of this work is to report 11 juvenile specimens of sailfish, Istiophorus platypterus, caught on three commercial fishing trips carried out in the Mexican Pacific Ocean, in July 1994 in the Gulf of Tehuantepec, in August 1994 at Cabo Corrientes and in September 1994 at the mouth of the Gulf of California. The sea surface temperature was 29.0ºC at the mouth of the Gulf of California, 29.0ºC at Cabo Corrientes and 32.0ºC in the Gulf of Tehuantepec. The minimum total length was 79 mm and minimum eye-fork length, 43 mm. The maximum total length was 218 mm and maximum eye-fork length. 105 mm. The capture of these fish indicates that the reproduction zone for sailfish extends at least from the mouth of the Gulf of California to the Gulf of Tehuantepec, which corresponds to the area with the highest abundance of adults in the Mexican Pacific Ocean.

The helminthological record of the California halibut, Paralichthys californicus, in Estero de Punta Banda. Todos Santos Bay and San Quintín Bay. Baja California, Mexico, is described. A total of 102 halibut was analyzed and 14 helminth species were identified: six were adult trematodes (Stephanostomum dentatum, Criptogoniminae, Metadena magdalenae, Opegaster parapristipomatis, Parahemiurus merus and Tubulovesicula lindbergi); six nematodes (Spirocamallanus pereirai, Philometra sp. and Hysterothylacium sp. in the adult stage, and Anisakis sp., Contracaecum sp. and Porrocaecum sp. as larvae); a cestode (Tetraphyllidea); and an acanthocephalan (Corynosoma strumosum) in the larval stage. At the three sites, Anisakis sp. larvae and the plerocercoids from the order Tetraphyllidea were important, due to their high values of abundance and prevalence. Anisakis sp. is important for humans, because of the risk it presents for contracting anisakiasis disease.
Gastropod mollusks from the continental shelf off Jalisco and Colima, Mexico: species collected with a trawl net
Authors: Pérez-Peña M , Ríos-Jara E
Published: August 2017

This study examines the distribution and abundance with respect to depth and type of substratum of 86 gastropod species collected from the Pacific continental shelf off Jalisco and Colima, Mexico, in August 1988. Sampling was performed with a trawl net at 22 stations, at depths of 18 to 112 m. A total of 582 individuals pertaining to 42 genera, 25 families, 4 orders and 3 subclasses of gastropods were collected. Abundance of gastropods was similar between 18 and 83 m, but the number of live individuals decreased between 41 and 60 m. Deep (61-83 m) stations registered the lowest diversity; however, the number of species collected alive decreased with depth. No gastropods were collected at stations deeper than 83 m. The number of individuals and species also varied with the type of substratum. Greater heterogeneity of the sediments was found at the shallower stations (18860 m) with medium sand, sandy silt and silty clay substrata. The greatest number of species were collected at stations with sandy silt and medium sand substrata. Total abundance was notably smaller in medium sand, while the abundance of live gastropods was higher in silty clay substratum. The seven most abundant species represented 5 1.2% of all of the individuals. Most of these species are of commercial interest, in particular those of the genera Fusinus, Hexaplex, Ficus, Harpa, Cantharus and Bursa.

Published: August 2017

The abundance and bathymetric distribution of juveniles of Lutjanus peru on the continental shelf of Jalisco and Colima, Mexico, were analyzed. Shrimp trawl samples were taken from three expeditions during one year. A total of 641 juveniles of L. peru were caught, ranging in total length from 3.7 to 21.9 cm and in weight from 0.6 to 153 g. The juveniles exhibited an aggregate spatial distribution pattern. Significant differences were observed in the bathymetric distribution of the organisms, since their occurrence was limited to shallow waters between 20 and 40 m depth. Two size classes were identified during the May-June cruise (DEM I) and the March cruise (DEM III), but only one class was found in the November-December cruise (DEM II). According to the growth model known for the species, the two size classes found could be of 1 and 1.5 years, respectively. Significant differences were observed in the individual sizes and weights among sites during DEM I and DEM III, whereas the average sizes and weights of DEM II were homogeneous among sites. The juveniles presented isometric growth in the size ranges analyzed.

Published: August 2017

Gillnet selectivity for Lutjanus guttatus and L. argentiventris in Navidad Bay, Jalisco (Mexico), was estimated using monthly samples. Gillnets of 7.62- and 8.89-cm mesh size were used for the experimental design; 475 organisms of L. guttatus and 134 organisms of L. argentiventris were caught. The results show that the organisms caught with the 8.89-cm mesh were on average 4 cm larger and 100 g heavier than those caught with the 7.62-cm mesh. For L. guttatus, the optimum length (100% retention probability) was 29.1 cm for the 7.62-cm mesh and 33.9 cm for the 8.89-cm mesh; for L. argentiventris, the optimum length for the 7.62-cm mesh was 28.9 cm and for the 8.89-cm mesh, 33.7 cm. In both cases the catch mode corresponds to the calculated optimum length. The gillnet of 7.62-cm mesh caught the largest abundance in terms of number of individuals and biomass; however, the 8.89-cm mesh assures the catch of organisms that have reached first maturity length.

The first check-list of marine fish larvae from the coasts of Jalisco and Colima (Mexico) is presented. The fish larvae were sorted from zooplankton samples collected with Bongo net during 11 oceanographic surveys between December 1995 and December 1996. A total of 102 taxa belonging to 50 families and 80 genera were identified. The families with the most number of species were Cynoglossidae, Carangidae and Paralichthydae. This collection represents the first step to future research on the biodiversity of fishes of this tropical region that has been little studied. The ichthyoplankton collection was catalogued and deposited in the Centro de Ecología Costera of the Universidad de Guadalajara, Mexico.
Natural history of Bimeria vestita Wright, 1859 (Hydrozoa, Bougainvilliidae) in the rocky intertidal of Mar del Plata (Argentina)
Authors: Genzano GN , Zamponi MO
Published: August 2017

The population dynamics, reproductive period and substrate preference of the hydroid Bimeria vestita Wright, 1859 were analyzed from October 1990 to February 1992 in the rocky intertidal zone of Mar del Plata (Argentina). Colonies were found year-round, with maximun abundances in summer and autumn (60% of the colonies). During these periods the colonies produce gonophores. Bimeria vestita is more frequently found on colonies of the hydroids Sertularella mediterranea Hartlaub, 1901 (58.1%) and Tubularia crocea (Agassiz, 1862) (37.5%) than on other substrates (4.4%). Seasonal differences in substrate preferences were observed. Tubularia crocea was the most preferred substrate in spring and summer (75–80%), while S. mediterranea was preferred in autumn and winter (70–80%). Stolonial growth of B. vestita suggests a "guerrilla" strategy to avoid competition in the basal zones of the substrates.
Seasonal variation in agar yield and quality of Gracilariopsis lemaneiformis (Bory) Dawson, Acleto et Foldvik, from the Gulf Of Califoria, Mexico
Authors: Arellano-Carbajal F , Pacheco-Ruíz I , Correa-Díaz F
Published: August 2017

Seasonal variation in agar from Gracilariopsis lemaneiformis (Bory) Dawson, Acleto et Foldvik from Bahía de las Ánimas was studied; samples were collected between August 1995 and May 1996. Minimum yield (81.6%) occurred in summer and maximum (15.37%) in autumn; 3,6-anhydrogalactose content (3,6-AG) fluctuated from 35.5% to 47.8% between autumn and winter. The sulfate percentage was 0.8% in winter and 2.7% in autumn. The lowest gel strength (217 g cm–2) was recorded in autumn and the highest in spring (892 g cm–2). Melting temperature varied from 92ºC in summer to 98ºC in spring, while gelling temperature was 34.3ºC in autumn and 37ºC in winter. Gel strength was positively correlated with 3,6-AG and melting temperature, and from summer to winter with gelling temperature. Correlation with sulfates was inverse and did not correlate with yield. Higher quality of agar in G. lemaneiformis coincides with the maximum in situ biomass.
Improvements in potentiometric determinations of the CO2 oceanic system using seawater sub-standards and CO2 reference materials
Authors: Ríos AF , Pérez FF
Published: August 2017

During the Cither 3 cruise along WOCE section A14, where 107 full-water column stations were surveyed, pH and alkalinity were measured potentiometrically. Corrections carried out on the raw data set have allowed us to improve the data quality. The correction procedure was focused on monitoring: (i) calibrations, (ii) liquid junction potential and (iii) seawater sub-standards; CO2 reference material (CRM) has been used to check this procedure. Accuracy of pH15 measurements (NBS scale) and alkalinity was 0.004 and 1.4 µmol.kg–1, respectively. Certified total inorganic carbon on CRM, batch 24, is 1987.55 µmol.kg–1. A value of 1987.8 ± 2.2 µmol.kg–1 was obtained following the correction procedure. This improvement was independently verified by means of the covariances between nitrate and pH, and between silicate and normalized alkalinity in North Atlantic Deep Water.
Shell variations of Siphonaria gigas (Sowerby, 1825) in response to the effect of wave intensity
Authors: Giraldo-López A , Gómez-Schouben C
Published: August 2017

A factorial sampling was conducted to determine the effect of wave intensity on shell length, height and thickness of the limpet Siphonaria gigas (Sowerby, 1835). The main objective was to distinguish between different wave intensity effects on each shell feature. The sampling was carried out at a sheltered and exposed rocky shore at Utría Cove, on the Pacific coast of Colombia. Wave intensity was found to be a determining factor (P < 0.001) in shell changes, producing short, thick shells on the exposed rocky shore.
Analysis of the process and observation error in recruitment estimates for the pacific sardine, Sardinops sagax caeruleus (Girard), off the southwest coast of the Baja California peninsula, Mexico
Authors: Morales-Bojórquez E
Published: August 2017

This paper analyzed the dynamics of the stock-recruitment relationship for the Pacific sardine Sardinops sagax caeruleus (Girard) off the southwest coast of the Baja California peninsula, Mexico, from 1981 to 1993. A maximum likelihood estimator was used to estimate the parameters of the model assuming two hypotheses: (a) process error in the model and (b) observation error in the data. The results showed that the hypothesis of the process error was accepted. The parameter values and confidence intervals (CI) were as follows: α = 2.7 (CI = 2.0–3.6, P < 0.05) and ß = 0.04 (CI = 0.03–0.05, P < 0.05), with σ = 0.58; the maximum value of the objective function L(REst\α, ß) = 1.16 x 10–5. In this paper, environmental variability is not interpreted as random variability (noise); the model was used to demonstrate and quantify effects of a statistical hypothesis on the possible stock-recruitment relationship, based on the error structure of the model and the stochastic effect on the parameters.
Bioaccumulation of metals in mussels from four sites of the coastal region of Baja California

Published: August 2017

This study analyzes the concentrations and variations of Cu, Mn, Zn, Al, Cd, Ag, As and Se among different size classes of Modiolus capax, from Punta Estrella, Bahía de los Ángeles and Santa Rosalía in the Gulf of California, and of Modiolus modiolus and Mytilus californianus, from Bahía Tortugas in the Pacific. During November 1988, mussels of these species were collected and 45 organisms were selected (three replicates of 15 organisms each). Their biometric variables were measured: large size (88–98 mm), medium size (70–87 mm) and small size (56–66 mm). The reference standards and procedural blanks were analyzed for each group of 15 samples. The results indicate that the geographic distribution and accumulation of metals in the different sizes are mainly influenced by the sources of input, bioavailability in each place and the biological condition of the organisms. The mussels presented Cu levels independent of size in the region, except at Santa Rosalía. Zn, Cd and Se showed strong regional variability, but no clear trend with respect to the size of the organisms. Al showed high regional variability and a tendency to accumulate in small organisms. As and Se presented higher concentrations in the large to medium mussels, regardless of the sampling site. Mn tended to accumulate in large and medium mussels and was dependent on the sampling site. In Bahía Tortugas, M. californianus accumulates Cu, Mn and Cd at a rate three times lower than M. modiolus at the same level of exposure. Within the Gulf of California, the geographic distribution of Mn, Al and Zn was similar, with higher concentrations in the northern part. This is probably because the mussels are exposed to these metals through the sedimentary material resuspended in the Colorado River Delta. Cd presented levels of 70 and 27 µg g–1 at Bahía Tortugas and Bahía de los Angeles, respectively; both sites are exposed to coastal upwelling. Cu presented relatively low levels (<35 µg g–1), except at Santa Rosalía (89 µg g–1), where Cu is mined. As, Se and Ag presented low variability in the study area, with low levels that reflect natural levels at the sites studied.
Growth rates and scales of sand banks in the Colorado River Delta
Authors: Carbajal N , Montaño Y
Published: August 2017

A linear stability analysis was carried out to investigate the sand bank formation in the Colorado River Delta. A truncated solution of the vorticity equation was included in the bottom evolution equation in order to evaluate the initial growth rates of the sand banks. The growth rates were estimated on the wave number plane for the hydrodynamic conditions of the Colorado River Delta, specifically for tidal ellipses, including unidirectional tides, and also for several depths. The wave lengths predicted with the model fluctuated between 2 and 7 km. These results agree quite well with the sand bank scales reported in the literature on the Colorado River Delta. The order of magnitude of the growth rates calculated in this study coincides with results obtained for the North Sea.

The construction of major dams in the Colorado River has produced a drastic effect on the amount of fresh water entering the Colorado River Delta. After 1935 there was a dramatic decrease in fresh-water input, causing ecological impacts and a decrease of organisms in the natural habitat. We carried out six spatial samplings during a period of no fresh-water inflow to the delta, in June, August and November 1989, and February, April and June 1990; during each sampling, a 24-hour time series was conducted at one station and seawater samples were taken every two hours. Also, in May 1991 we carried out an eight-day time series, taking samples of seawater at 08:00, 12:00 and 16:00 hours. The objective was to estimate phytoplankton abundance, chlorophyll concentration and primary productivity during a period of no fresh-water input. In the spatial distribution, the chlorophyll a concentrations and phytoplankton abundance were higher on the Baja California side than on the Sonora side, with concentrations of 2.6–18.2 mg m–3 and 1.8–12.7 mg m–3 and of 274 and 166 cells mL–1, respectively. In the time series, the dinoflagellates were more abundant than the diatoms. The primary production showed a tendency to decrease from August 1989 to June 1990, with values of 15.0 to 0.5 mgC m–1. The primary productivity values in the time series presented a tendency to increase during the tide transition, reaching values of 76 mgC m–1. The variations of chlorophyll concentration, phytoplankton abundance and primary productivity were strongly influenced by the effects caused by the tidal currents.
Seasonal and spatial characterization of the Gulf of California phytoplankton photosynthetic parameters
Authors: Valdez-Holguín JE , Álvarez-Borrego S , Trees CC
Published: August 2017

Photosynthesis-irradiance and phytoplankton absorption data from waters of the central Gulf of California, as well as data in the literature, were analyzed in order to propose working averages of the physiological parameters of phytoplankton to estimate primary productivity at large time and space scales. Since there is substantial variability within data sets, we conclude that it is not possible at this time to predict fine time- and space-scale variation in photosynthetic parameters. We recommend the following working averages for the whole Gulf of California and for "winter" conditions (surface TºC <22ºC): a surface P*max = 9.6 ± 2.4 mgC mgChl–1 h–1 (assimilation number), with a linear variation between this and 3.7 ± 0.3 at the middle of the euphotic zone (ez), and then a constant value for deeper waters; a single value of α*inc = 0.029 ± 0.004 mgC mgChl–1 h–1 (μmol quanta m–2 s–1)–1 (incubator´ s initial slope); and φmax = 0.06 ± 0.01 molC (mol quanta)–1 (quantum yield of photosynthesis). For "summer" conditions we recommend: a surface P*max = 3.7 ± 0.3, with a linear variation between this and 1.5 ± 0.2 at the middle of the ez, and another linear variation between the latter and 0.4 ± 0.1 at the bottom of the ez; a surface α*inc = 0.013 ± 0.001, with a linear variation between this and 0.001 at the bottom of the ez; and a single value φmax = 0.014 ± 0.002. A procedure is given to correct α*inc for the in situ spectral distribution of light to obtain α*in situ.
