ABSTRACT Alterations in blood cell counts are the most prominent and recurrent clinical findings among patients suffering from both acute and chronic liver disease. These changes are an important marker of liver failure and often play a key role in the evaluation and management of these patients. Together with the prolongation of coagulation tests, thrombocytopenia is the most common disorder among these individuals. This condition, as well as leukopenia, is largely attributable to hypersplenism, a disorder in which the spleen retains and destroys blood cells, including platelets. However, when the platelet count drops below 10x103/µl, it is essential to consider other causes, such as autoimmune factors that may be contributing to the development of thrombocytopenia. Anemia, defined as a decrease in red blood cell count or hemoglobin levels, is another common characteristic of liver disease. Although in most cases macrocytic anemia occurs, in some situations it can be secondary to hemolytic events, as observed in Zieve’s syndrome. This wide range of manifestations of anemia among liver patients highlights the complex interaction between liver and blood components. Despite advances in understanding the underlying causes of these cytopenias, treatment options remain limited. Therapeutic options generally focus on the transfusion of blood products to compensate for deficiencies in cell counts or on the use of thrombopoietin (TPO) analogues to temporarily stimulate platelet production in the bone marrow. However, these treatments tend to address the symptoms rather than the root causes of hematologic disorders in liver disease. The persistence and worsening of these disorders may serve as early indicators of the progression of liver failure. The complicated relationship between liver and hematological homeostasis remains the subject of research. A deeper understanding of these mechanisms could potentially open the door toward more targeted and effective therapeutic approaches to address cytopenias in the context of liver disease.

RESUMEN Las alteraciones en los recuentos celulares sanguíneos representan los hallazgos clínicos más notorios y recurrentes en pacientes que padecen enfermedad hepática, tanto aguda como crónica. Estos cambios constituyen un marcador importante de la disfunción hepática y, a menudo, desempeñan un papel crucial en la evaluación y manejo de estos pacientes. En conjunto con el alargamiento de las pruebas de coagulación, la trombocitopenia es la irregularidad más prevalente en estos individuos. Esta condición, así como las leucopenias, se le atribuye en gran medida al hiperesplenismo, una alteración en la que el bazo retiene y destruye las células sanguíneas, incluidas las plaquetas. Sin embargo, cuando el conteo plaquetario desciende por debajo de 10 x 103/µl, es fundamental considerar otras causas, como factores autoinmunitarios que pueden estar contribuyendo con la trombocitopenia. La anemia, definida como una disminución en el número de glóbulos rojos o en los niveles de hemoglobina, es otra característica constante que acompaña a la enfermedad hepática. Aunque en la mayoría de los casos la anemia es macrocítica, en algunas situaciones puede ser secundaria a eventos hemolíticos, como lo observado en el síndrome de Zieve. Esta diversidad en las manifestaciones de la anemia en pacientes hepáticos subraya la complejidad de las interacciones entre el hígado y los componentes sanguíneos. A pesar de los avances en la comprensión de las causas subyacentes de estas citopenias, las opciones del tratamiento siguen siendo limitadas. Generalmente, las opciones terapéuticas se enfocan en la administración de transfusiones de hemocomponentes para compensar las deficiencias en los recuentos celulares o en el uso de análogos de trombopoyetina (TPO) para estimular temporalmente la producción de las plaquetas en la medula ósea. No obstante, estos tratamientos tienden a abordar los síntomas más que las causas fundamentales de las alteraciones hematológicas en la enfermedad hepática. La persistencia y el empeoramiento de estas alteraciones pueden servir como indicadores tempranos de la progresión de la disfunción hepática. La relación intrincada entre el hígado y la homeostasis hematológica continúa siendo objeto de investigación, la compresión más profunda de estos mecanismos podría abrir potencialmente la puerta hacia enfoques terapéuticos más específicos y efectivos para abordar las citopenias en el contexto de la enfermedad hepática.

Abstract: The clay fraction of earthen plasters is the part responsible for the acquisition of cohesion and adherence that they possess against deterioration factors. Adherence is the property responsible for keeping the plaster together with the wall and is influenced by the percentage content of clay as well as by its mineralogy and the heterogeneity of minerals that may be present. However, it is still unknown in depth how clay minerals perform in the adherent properties of earthen plasters when the composition is heterogeneous in the material. The objective of this study is to evaluate the incidence of the mineralogical complexity of clay mineralogy in the variability of the adherence of earth plasters. To evaluate the variability, considering that the mineralogy of the soils depends directly on the place and the formation processes, eight soils from Tucumán (Argentina) corresponding to different physiographic units were analyzed. A methodology was designed for sample preparation that allows soils to be compared through adhesion tests. They were characterized by XRD to determine their mineralogical composition and by the hydrometric method to determine their granulometry. To evaluate the adherence of mixtures made with the respective soils, it was proposed in the first instance to compensate the granulometry of the soils to equate them and, once the plasters were made, this property was evaluated through shear and pull-off tests. The results showed that they allowed us to identify that the soils presented a pattern of mineralogical composition common to all the physiographic units, made up of the Ill and K pair, the former being predominant. For this pattern, it was observed in particular that there is a positive correlation between the increase in Ill content with the increase in the adhesive strength of the plasters. Clay minerals from the Sm group also contribute to the increase in adherence when the percentage is greater than or equal to 11%. On the contrary, K and Cl do not influence the increase in adhesive strength

Data assimilation has been widely used for improvement of crop models’ estimates, for example to incorporate the effects of external events or compensate calibration errors in large areas. The term describes multiple approaches for those who want to take advantage of satellite imagery to reduce uncertainty or improve accuracy of model estimates. Kalman Filters are among the most used methods for achieving these goals. But their use in new contexts, i.e., from open field to protected environments, requires untangling aspects of the pipeline that are often performed in many different ways without guidelines, such as which variables to assimilate or how to ascribe uncertainty to observations or model estimates. This study is then divided in two parts. In the first, we review details on how uncertainty is ascribed on crop model estimates and in observations for applications of the Kalman Filter and three variations of the method, i.e., the Extended, Unscented and Ensemble, as well as which state variables are often updated and the frequency with which assimilation may occur, as well as how these aspects are connected to each other. In the second part, we apply different approaches from the reviewed literature in a greenhouse tomato crop model. We use artificial data with controlled noise levels as well as artificial data generated by simulation using other tomato crop model. We assess the impacts of using different methods and different approaches for ascribing uncertainty in model estimates and in observations, by assimilating artificial observations of fruit and of mature fruit biomass. We note that covariances should not be fixed values, that there are trade-offs between ascribing model uncertainty to the state itself and to other elements of the process, that observation covariance may have been considered disproportionality higher when using some ensemble generation approaches in the EnKF, and that bias in model estimates may lead to worse outcomes even when observations are high-quality ones. While we discussed aspects that should be considered in a new environment, many of them are also important for field crops, and we concluded assimilation should follow an assessment of which variables could be useful for assimilation.

Abstract Pathogenic DNA alterations in GJB2 are present in nearly half of non-syndromic hearing loss cases with autosomal recessive inheritance. The most frequent variant in GJB2 causing non-syndromic hearing loss is the frameshifting c.35del. GJB2 encodes Cx26, a protein of the connexin family that assembles hemichannels and gap junctions. The expression of paralogous proteins is believed to compensate for the loss of function of specific connexins. As Cx26 has been involved in cell differentiation in distinct tissues, we employed stem cells derived from human exfoliated deciduous teeth (SHEDs), homozygous for the c.35del variant, to assess GJB2 roles in stem cell differentiation and the relationship between its loss of function and the expression of paralogous genes. Primary SHED cultures from patients and control individuals were compared. SHEDs from patients had significantly less GJB2 mRNA and increased amount of GJA1 (Cx43), but not GJB6 (Cx30) or GJB3 (Cx31) mRNA. In addition, they presented higher induced differentiation to adipocytes and osteocytes but lower chondrocyte differentiation. Our results suggest that GJA1 increased expression may be involved in functional compensation for GJB2 loss of function in human stem cells, and it may explain changes in differentiation properties observed in SHEDs with and without the c.35del variant.

Resumo O pagamento por serviços ecossistêmicos (PES) é um mecanismo no qual um consumidor é capaz e está pronto para pagar pela proteção do serviço ecossistêmico preciso e deve haver um provedor, como sociedades locais, que recebe um recurso econômico, que, em troca, deve ter capacidade para manter esse serviço ecossistêmico. A avaliação econômica fornece a base para o pagamento de serviços ecossistêmicos. Portanto, o objetivo deste estudo foi avaliar os serviços de turismo e estoque de carbono do território da capital de Islamabad (ICT), Paquistão. Duas zonas florestais (Chirpine e Scrub) do território da capital de Islamabad (ICT) foram selecionadas para estimativa do estoque de carbono e seus créditos de carbono e valor de carbono. Uma pesquisa baseada em questionário foi realizada para turismo como pagamento por serviços ecossistêmicos. O método para avaliação do estoque de carbono foi a amostragem sistemática para a floresta de Chirpine, enquanto a amostragem aleatória foi feita para a floresta de cerrado. O tamanho da parcela de amostragem foi de 17,84 m de raio, e um total de 93 parcelas (49 zona Scrub e 44 zona Chirpine) foi considerado na área de estudo. O estoque de carbono de ambas as zonas (zona Chirpine e Scrub) é de 22.556,75 ton/ha (Chirpine 20.105,79, Scrub 2.450,96), e o dióxido de carbono total sequestrado por ambas as zonas é de 82.557,72 ton/ha (Chirpine 73.587,2, Scrub 8.970,52); créditos totais de carbono de ambas as zonas são 302.160,87 (Chirpine 269.328,97, Scrub 32.831,9), e o valor de carbono tanto do Chirpine quanto da zona de scrub é 4.532.418,92 $ (Chirpine 4.039.937,09 $, Scrub 492481,83 $). Da mesma forma, do ponto de vista do turismo, em Shakar Parian 94% dos turistas concordaram com o PES, enquanto 6% discordaram do PES (6% dos turistas não concordaram em contribuir para o PES, 40% concordaram com a contribuição de R$ 5 e 54% para R$ 10). além disso, no Lake View Park, 97% dos turistas concordaram e 3% discordaram (no Lake View Park, 5% dos turistas discordaram da contribuição do PES, enquanto 32% concordaram em R$ 5 e 63% foram em R$ 10). Em Damen e Koh, cerca de 87% dos turistas concordaram e 13% discordaram (24% concordaram com a contribuição de R$ 5 e 63% dos turistas concordaram com a contribuição de R$ 10). No Jardim Zoológico de Marghazar, 93% dos turistas concordaram (22% aceitaram a contribuição de R$ 5 e 71% dos turistas aceitaram contribuir com R$ 10) e 7% discordaram para PES. enquanto 7% turistas não foram acordados para contribuição. O PSA pode ser implementado para compensar o gestor florestal e de parques para garantir uma melhor gestão de florestas e parques. Devido à localização privilegiada e beleza cênica do ICT, possui enorme potencial para implementação de mecanismo de PSA para manejo e conservação florestal sustentável. Portanto, recomenda-se que a autoridade de desenvolvimento da capital (CDA) de Islamabad elabore um plano para implementação de PES em florestas e parques de ICT para sua gestão sustentável de recursos recreativos e florestais.

Abstract Payment for ecosystem services (PES) is a mechanism where a consumer is able and ready to pay for the protection of the precise ecosystem service and there must be a provider such as local societies receiving an economic resource, who in return, must have the ability to maintain that ecosystem service. Economic valuation provides basis for payment for ecosystem services. Therefore, objective of this study was to evaluate tourism and carbon stock services of the Islamabad Capital Territory (ICT), Pakistan. Two forest zones (Chirpine and Scrub) of Islamabad capital territory (ICT) were selected for estimation of carbon stock and their carbon credits and carbon worth, a questionnaire-based survey was conducted for tourism as a payment for ecosystem services. The method for carbon stock assessment was systematic sampling for Chirpine forest whereas random sampling was done for scrub forest. The size of sampling plot was 17.84 m radius, and a total of 93 plots (49 Scrub zone and 44 Chirpine zone) was taken in the study area. The carbon stock of both zones (Chirpine and Scrub zone) is 22556.75 ton/ha (Chirpine 20105.79, Scrub 2450.96) and total carbon dioxide sequestered by both zone is 82557.72 ton/ha (Chirpine 73587.2, Scrub 8970.52), total carbon credits of both zone is 302160.87 (Chirpine 269328.97, Scrub 32831.9) and the carbon worth of both Chirpine and scrub zone is 4532418.92 $ (Chirpine 4039937.09$, Scrub 492481.83$). Similarly, from tourism point of view, in Shakar Parian, 94% tourists were agreed for PES whereas 6% were disagreed for the PES (the 6% tourist were disagreed to contribute for PES, 40% were agreed for Rs.5 contribution and 54% for Rs.10.). moreover, in Lake view Park, 97% tourists were agreed and 3% are disagreed (In Lake View Park 5% tourists were disagreed for the PES contribution whereas 32% were agreed for Rs.5 and 63% were for Rs.10). In Damen e Koh, around 87% tourist were agreed and 13% were disagreed, (24% were agreed for the contribution of Rs.5 and 63% tourists were agreed for the contribution of Rs.10). In Marghazar Zoo, 93% tourists were agreed (22% were agreed for contribution of Rs.5 and 71% tourist were agreed for contribution of Rs.10) and 7% are disagreed for PES whereas 7% tourists were not agreed for contribution. PES may implement to compensate forest and parks manager to ensure better management of the forests and parks. Due to prime location and scenic beauty of the ICT, it has huge potential for implementation of PES mechanism for sustainable forest management and conservation. Therefore, it is recommended that Capital Development Authority (CDA) Islamabad should devise a plan for implementation of PES in forests and parks of ICT for its sustainable management of recreational and forest resources.

Abstract To connect the protection of natural resources to economic development, environmental rehabilitation is a promising way to repair and compensate for impacts on biodiversity and ecosystem services. Here, we aimed to compare and select potential indicators for the success of different rehabilitating ecosystems to quantify gains in biodiversity and ecosystem services within the Impact Mitigation Hierarchy. We sampled nine environmental variables along rehabilitation chronosequences from rehabilitating (i) iron mining waste piles, (ii) sand quarries, and (iii) compensation areas in the Carajás National Forest. From that, we computed the rehabilitation status, i.e., the proportion of environmental enhancements compared to the overall rehabilitation trajectory, and statistically validated the indicators that best described the status. With a mean rehabilitation status for the oldest rehabilitation stages from waste piles, sand quarries, and compensation areas of 52, 71, and 74%, respectively, we confirmed that rehabilitation activities were able to generate considerable gains in biodiversity. In all the cases, the Shannon diversity, phylogenetic diversity and Leaf Area Index performed better than did the other indices, encouraging the increased use of these indices for upscale monitoring activities. Consistent indicators across distinct projects highlight the importance of maximizing tree diversity and canopy closure in rehabilitation projects to increase biodiversity gains within Impact Mitigation Hierarchy. development Here Hierarchy i (i piles ii (ii quarries iii (iii Forest ie e i.e. trajectory 52 71 74 74% respectively cases i.e 5 7

This work starts from the Fisher-Kolmogorov-Petrovskii-Piskunov (FKPP) equation to model diffusive populations in fragmented regions characterized by patches with different environmental conditions. Using this model, we found an expression for the general case of critical patch size, i.e. sizes below which the population goes extinct in a system of two patches (life-beneficial regions) surrounded by sinks (life-detrimental regions). This expression alone is an interesting result because it allows for the study of phenomena and interpretations presented in this work, as well as other features not included in this study. From the analysis of this expression, we extracted the analytical prediction that in a system formed by a patch and two semi-infinite sinks, if we replace one semi-infinite sink with a patch plus another semi-infinite sink, more lethal than the original, the added patch will only be beneficial to the original system if it is large enough to compensate for the added sink. This interpretation arises from a case study done with a specific set of parameters, but will appear for other values that meet the presented condition.

Resumen: Antecedentes: El uso de alcohol se asocia a mayor desinhibición, pero estos hallazgos podrían no ser representativos de toda la población ya que predominan estudios en contextos especializados y casos severos. Aquí, incorporamos una nueva batería de evaluación de la desinhibición (Cognitive Impulsivity Suite o CIS) en una web de tratamiento online con acceso a una población más amplia (https://www.counsellingonline.org.au/). Método: Participantes de 18 a 64 años (N = 137; 109 mujeres) completaron vía web el “Alcohol-Use Disorders Identification Test” y la CIS, que evalúa tres componentes de la desinhibición (Control Atencional, Acumulación de Información y Monitorización / Cambio). Clasificamos en grupos de alto-riesgo versus bajo-riesgo aplicando un análisis de clases latentes sobre las puntuaciones del AUDIT. Usamos análisis de regresión para asociar las dos clases resultantes con las medidas de la CIS. Resultados: Alto-riesgo en el consumo de alcohol se asoció con peor rendimiento en Control Atencional y Monitorización / Cambio. La pertenencia al grupo de alto-riesgo se asoció con menor eficiencia en la acumulación de información en participantes de mayor edad. Conclusiones: Revelamos nuevas asociaciones entre el consumo de alcohol de riesgo y el rendimiento cognitivo en distintos componentes de la desinhibición en participantes que buscaban asistencia en una web de tratamiento online.

Abstract: Background: Cognitive disinhibition underpins alcohol and drug use problems. Although higher-risk substance use is consistently associated with poorer disinhibition, current findings may be limited by narrow recruitment methods, which over-represent individuals engaged in traditional treatment services with more severe presentations. We embedded a novel gamified disinhibition task (the Cognitive Impulsivity Suite; CIS) in a national online addiction support service (https://www.counsellingonline.org.au/). Method: Participants aged 18 to 64 (N = 137; 109 women) completed the Alcohol-Use Disorders Identification Test (AUDIT) and Drug Use Disorders Identification Test (DUDIT) along with the CIS, which measures three aspects of disinhibition (Attentional Control, Information-Sampling, and Feedback Monitoring/Shifting). The majority of the sample comprised people with alcohol use, and AUDIT scores were differentiated into ‘higher-risk' or ‘lower-risk' groups using latent-class analysis. These classes were then regressed against CIS performance measures. Results: Compared to lower-risk, higher-risk alcohol use was associated with poorer attentional control and feedback monitoring/shifting. While higher-risk alcohol use was associated with slower information accumulation, this was only observed for older adults, who appeared to compensate with a more conservative response criterion. Conclusions: Our results reveal novel relationships between higher-risk alcohol use and specific aspects of disinhibition in participants who sought online addiction help services.

Abstract Objective To find out if motion sickness susceptibility (MSS) of vestibular migraine (VM) patients and migraine only (MO) patients can be reliably detected with a single simple question: “Can you read while travelling in a car without getting motion sick?”. Method Ninety-two definite VM and 58 MO patients and 74 healthy control (HC) subjects were asked about their MSS and about being able to read while riding in a car without becoming motion sick. A Motion Sickness Susceptibility Questionnaire (MSSQ-Short) including childhood (MSA), adulthood (MSB) and total (MST) parts was also administered to all participants. ROC curves of MSSQ-Short were prepared for “not being able to read in a car” as the gold standard. Results Mean MSA scores were significantly higher in both VM and MO patients than in HCs (p< 0.001), but their scores were not significantly different (p= 0.171). Mean MSB and MST scores were significantly higher in VM than in MO patients (p< 0.001) and both VM and MO patients had significantly higher scores than HCs (p< 0.001). MSA scores were significantly higher than MSB scores in MO patients (p< 0.001). All sections of the questionnaire were associated with high area-under-curve values for MSS detected by the question about being able to read in a car without becoming motion sick. Conclusion We propose that all migraine patients could have the same level of MSS in childhood but MO patients are able to compensate over years, but VM patients are not. A quick way to determine MSS is to ask about the ability to read without becoming motion sickness while riding a car.

ABSTRACT Peru holds a high mammalian diversity in its Amazonian region, with 326 species. However, our knowledge about the actual diversity is still considered incomplete, and the molecular information for those species in genetic databases is even less comprehensive. To assess the availability of genetic information for Peruvian Amazonian mammals relative to known diversity, we surveyed the Amazonian mammals with at least one molecular marker in the most widely used repositories for nucleotide sequences, GenBank and BOLD Systems. Our survey focused on widely used molecular markers in evolutionary biology-cytochrome b [cyt-b], cytochrome oxidase I [COI], 12S ribosomal RNA [12S], and the mitogenome [mit]-derived from Peruvian Amazon mammals. Additionally, to gain insights into the current mammalian sampling effort in Peruvian Amazonia, we generated a map of unique sampling localities and a heat map, utilizing 41951 records, which identified six major information gaps. This comprehensive analysis found 1597 genetic sequences corresponding to 180 mammalian species (55.2% of Peruvian Amazonian species): COI (38 species), cyt-b (167 species), 12S (56 species), and mitogenome (16 species). Taxonomically, Rodentia (53 species, four markers), Chiroptera (63 species, three markers), and Didelphimorphia (27 species, four markers) represented most molecular data, with a concentration of molecular markers in the orders Chiroptera (703) and Rodentia (499). Geographically, the Loreto department has the largest genetic information (530 records, 99 species). These results confirm a worrying underrepresentation of Peruvian Amazonian diversity in molecular databases. Consequently, we advocate for the use of scientific collections as an alternative source to systematically generate genetic information for the Amazonian mammal diversity in Peru to compensate for the current underrepresentation. region 32 However incomplete Systems biologycytochrome biology cytb, cytb cyt , [cyt-b] COI, [COI] S 12S, [12S] mitderived mit derived Additionally Amazonia 4195 records gaps 159 18 55.2% 552 55 2 (55.2 species) 38 (3 167 56 (5 16 (1 .

Resumo: A inércia social percebida tem sido negativamente associada ao desempenho de equipas. No entanto, muito pouca atenção tem sido dada aos mecanismos subjacentes a esta associação. O objetivo do presente estudo é investigar não apenas a relação direta entre a inércia social percebida e o desempenho da equipa, mas também a relação indireta entre essas duas variáveis através do papel mediador do ‘efeito do idiota’ / compensação social e da inércia social continuada daqueles que são socialmente inertes. A pesquisa por questionários foi realizada com 360 estudantes de uma universidade pública do Vietname em 2021. Os resultados do presente estudo confirmam resultados anteriores em que a inércia social percebida influência negativamente o desempenho das equipas. O resultado mais surpreendente teve a ver com o ‘efeito do idiota’ que não apresentou correlações com nenhuma outra variável em estudo, enquanto que a compensação social e a inércia social continuada são mediadores na relação entre a inércia social percebida e o desempenho das equipas. Especificamente, quando os estudantes universitários percebiam inércia social nos seus colegas de equipa esforçavam-se mais para compensar essa inércia social e, dessa forma, os inertes sociais continuavam a esforçar-se menos, contribuindo para que o desempenho total da equipa fosse baixo.

Abstract: Perceived social loafing has been found to be negatively related to team performance. However, far too little attention has been paid to the underlying mechanism of this association. The purpose of the present study is to investigate not only the direct relationship between perceived social loafing and team performance but also the indirect relationship between these two variables via mediating roles of the sucker effect/social compensation and social loafer’s continuous social loafing. A questionnaire survey was conducted with 360 students of a public university in Vietnam in 2021. The current study confirmed the previous finding that perceived social loafing could negatively influence team performance. The most striking result to emerge from the data was that the sucker effect had no correlation with any other variables while social compensation and social loafer’s continuous social loafing were two serial mediators in the relationship between perceived social loafing and team performance. Specifically, when students perceived that their teammates engaged in social loafing, they exerted more effort to compensate for the social loafers, this way of reaction made the social loafers continue putting forth less effort and, in consequence, the overall team performance was low.

Abstract This paper investigates the Ricardian Equivalence (RE) under collateralized debt, default, transaction costs and incomplete markets. The public debt is neutral and the RE holds only if the collateral-transfer cost depends linearly on the lump-sum tax and is fully offset. Lenders and borrowers should enter in a voluntary agreement to compensate for any transfer cost under default. However, any perturbation in the assumed affine relation undermines the debt neutrality. It is not the transaction cost per se that invalidates the RE, but rather how this cost affects the households’ indebtedness and budget constraint. The underlying mechanism is the credit channel of the fiscal policy. Whenever the transfer cost is not fully offset, there is a net tax balance leftover that affects the budget set and real allocations. This is fundamentally different from a liquidity constrained economy because the credit channel of the fiscal policy is binding and uncompensated transaction costs lead to the RE failure. (RE default markets collateraltransfer collateral lumpsum lump sum offset However neutrality households constraint allocations failure

Resumo Este artigo investiga a Equivalência Ricardiana (ER) sob dívida colateralizada, inadimplência, custos de transação e mercados incompletos. A dívida pública é neutra e a RE é válida somente se o custo da transferência de garantias depender linearmente do imposto lump sum e for totalmente compensado. Credores e tomadores devem celebrar um acordo voluntário para compensar quaisquer custos de transferência em caso de descumprimento. Contudo, qualquer perturbação na relação afim assumida compromete a neutralidade da dívida. Não é o custo de transação em si que invalida a RE, mas sim a forma como este custo afeta o endividamento e a restrição orçamentária das famílias. O mecanismo subjacente é o canal de crédito da política fiscal. Sempre que o custo da transferência não é totalmente compensado, há uma sobra de saldo tributário líquido que afeta o conjunto orçamentário e as dotações reais. Isto é fundamentalmente diferente de uma economia com restrições de liquidez porque o canal de crédito da política fiscal é ativo e os custos de transação não compensados levam ao fracasso da ER.

SUMMARY Payment for ecosystem services (PES) is an economic tool that seeks to compensate landowners for the conservation of their forested lands and reduce the negative impacts of land use change in forest areas that are important for the provision of ecosystem services (ES). However, it is essential to verify that the implementation of this mechanism is focused on where it is most needed. In this study, an analysis of the evolution of PES in the Pixquiac sub-basin in Veracruz was carried out, and the degree of coincidence between the supported areas and hydrological priority areas was evaluated. Information regarding the fiscal years of PES in the region from 2003 - 2016 was statistically analyzed, and the priority areas and areas of PES were determined using geographic information systems. Results showed that payments amounted to USD 1,076,782 in an area of 5,450 ha during the period analyzed. However, only 881.58 ha (24.5 % of the total hydrological priority areas) were considered in this payment scheme. Decision-makers must have up-to-date information that allows them to focus available resources at a more precise spatial scale. In addition, efforts must be made by the actors involved to ensure greater participation by forest owners and ecosystem service users.

RESUMEN El pago por servicios ambientales (PSA) es una herramienta de mercado que busca compensar a los dueños por la conservación de sus terrenos forestales y aminorar la problemática del cambio de uso de la tierra en zonas boscosas importantes para la provisión de servicios ambientales (SA). Sin embargo, en su implementación, resulta fundamental verificar que este mecanismo se focalice a donde realmente se requiere. En el presente estudio se analizó la evolución del PSA en la subcuenca Pixquiac, Veracruz y evaluó el grado de coincidencia entre las áreas apoyadas y áreas prioritarias hidrológicas. Para ello, se analizó estadísticamente la información de los ejercicios fiscales del PSA en la región durante 2003 - 2016, con sistemas de información geográfica se determinaron las áreas prioritarias y áreas de PSA. Los resultados mostraron que el monto de pago ascendió a USD $1.076.782 en una superficie de 5.450 ha durante el periodo analizado. Sin embargo, solo 881,58 ha (24,5 % del total de áreas prioritarias hidrológicas) fueron consideradas en este esquema de pago. Es necesario que los tomadores de decisiones cuenten con información oportuna que permita focalizar los recursos disponibles a una escala espacial más precisa. Además, se deben conjuntar esfuerzos por parte de los actores involucrados para que exista mayor participación de los dueños de los bosques y usuarios de los SA.

Abstract Purpose This paper assumes necessity rather than sufficiency logic to model the relationship between collaborative culture and supply chain collaboration as triangular rather than linear. Specifically, this study aims to determine whether overall collaborative culture and its dimensions (i.e. collectivism, long-term orientation, power symmetry and uncertainty avoidance) are necessary for supply chain collaboration and the minimum levels of overall collaborative culture and its dimensions that are required for high levels of supply chain collaboration. Design/methodology/approach Based on the literature, collaborative culture and its four dimensions, namely, collectivism, long-term orientation, power symmetry and uncertainty avoidance, were modelled as conditions having supply chain collaboration as their outcome. The study used the necessary condition analysis to test the triangular relationships between the conditions and the outcome among a sample of firms (N = 166) in the downstream petroleum sector. Findings The results revealed that collaborative culture and its dimensions are necessary conditions for supply chain collaboration, and that high levels of collaboration are possible, although not guaranteed when at least a basic level of collaborative culture or its dimensions are present. Hence, different levels of supply chain collaboration require firms to have different levels of collectivism, long-term orientation, power symmetry and uncertainty avoidance. Thus, at 30% supply chain collaboration, only overall collaborative culture is necessary. Research limitations/implications A significant limitation of this research is that, although several antecedents of supply chain collaboration exist, this study explored only the cultural antecedents of supply chain collaboration. Practical implications The dimensions of collaborative culture are necessary but not sufficient for supply chain collaboration. Therefore, managers should adopt a holistic approach to investment in a collaborative culture, as an over-investment in any of the dimensions may not compensate for an under-investment in the others. Originality/value As one of the first studies to use necessity rather than sufficiency logic to test the relationship between collaborative culture and supply chain collaboration, this research unearthed the non-linear (triangular) relationship between the constructs. It contributes to understanding how collaborative culture and its dimensions serve as bottleneck conditions constraining supply chain collaboration. linear Specifically i.e. ie i e (i.e collectivism longterm long term orientation avoidance Designmethodologyapproach Design methodology literature namely N 166 sector possible present Hence Thus 30 limitationsimplications limitations exist Therefore overinvestment over underinvestment under others Originalityvalue Originality value nonlinear non (triangular constructs i.e 16 3 1

Abstract Introduction Older individuals often report that they find it difficulty in enjoying watching television since they find it hard to follow the rapid intensity variations, and voice changes from scene to scene. Objective The present study investigated the effect of coupling the hearing aid with the television via Bluetooth on audiovisual speech recognition and quality rating of compressed speech in older individuals with hearing loss. Method Twenty participants in the age range of 60 to 75 years who had moderate to moderately severe sloping sensorineural hearing loss were bilaterally fitted with digital receiver in the canal hearing aids. The hearing aid was coupled with a television via Bluetooth using a streamer. The video recorded stimuli were presented at 65 dB SPL at normal rate, 35% compression and 45% compression conditions. Speech recognition scores and quality ratings were obtained for each condition with and without the Bluetooth streamer connected to the hearing aids. Results Speech recognition scores were significantly better with Bluetooth coupling compared with conventional hearing aid use at 40% compressed speech rate. The quality was also rated higher in almost all parameters across speech rates when Bluetooth was used. Conclusions The improved clarity and nullification of room reverberation offered by Bluetooth coupling can potentially compensate for the age-related temporal processing deficit contributing to ease of listening. variations 6 7 aids rate 35 45 conditions 40 used agerelated related listening 3 4
