Limpets (Patella spp.) are marine gastropods that inhabit rocky shores along the coasts of Europe, the Mediterranean, Macaronesia and the north-west coast of Africa. Being considered key species, limpets have an important role regulating algal assemblages in coastal communities. The goal of this work was to evaluate the influence of sea temperature on the respiration rate of four limpet species occurring in mainland Portugal, in line with predictions from the metabolic theory of ecology. The individuals were collected from rocky shores in Portugal and exposed to sea temperatures ranging from 6–28°C for respiration rate assessments. Following the estimation of the relationship between oxygen consumption and temperature the activation energy was calculated. In parallel, low and high thermal thresholds were determined for three of the species. The results indicated that P. ulyssiponensis oxygen consumption increased linearly with sea temperature and the remaining species presented the same tendency. The values of activation energy ranged between 0.33–0.76 eV. For P. ulyssiponensis, the highest activation energy indicated that this species is more sensitive to temperature variations while for the tested temperatures it presented a higher thermal tolerance limit than the other species. Such findings indicate that P. ulyssiponensis is the most susceptible of these species to climate change, in line with the tolerance–plasticity trade-off hypothesis. This work provides a good starting point for understanding the effect of sea temperature on oxygen consumption in Patella spp. and for comprehending sensitivity of limpets to temperature increases under future climate change scenarios.

Current approaches to voting behavior in clientelist contexts either predict that clients leave their preferences aside for fear of having their benefits cut off or voluntarily support politicians they perceive to be reliable patrons. These two approaches cannot account for clients’ vote choices in the Sertão of Bahia, Brazil, where voters were free to choose among competing candidates but supported patrons they knew were unreliable. This article argues that clients voluntarily voted for bad patrons as a strategy to gain symbolic power in their negotiations with politicians. By explaining clients’ paradoxical choices in the Sertão, this article reveals how clientelism can persist without monitoring mechanisms or positive attitudes toward patrons. In addition, this study shows the importance of incorporating voters’ perspectives and their everyday survival strategies to better account for clients’ political behavior.

Variation in water colour is a remarkable characteristic of Amazonian rivers and reflects their limnological properties and the geomorphology of sub-basins. We present here a literature-based study to examine the relationships between fish species turnover and abiotic properties of Amazonian rivers with contrasting water colours. We analysed fish records and water physicochemical properties (pH, colour, turbidity, dissolved oxygen, ammonia and suspended solids) of eight Amazonian rivers with white-, black- and clearwaters. Rivers with similar water colour shared more fish species than those that contrasted in colour. Increased differences in abiotic parameters imply an increased dissimilarity in fish species composition. Species composition is also related to distance among rivers with high dissimilarity observed in rivers distant to each other. The fish species turnover could be ultimately driven by the geological history of rivers which provides different opportunities to speciation and biotic interchange. Water types likely influence species turnover by selecting fishes with different limits of physiological tolerance and specialized use of different habitat types. Our findings suggest that river water colours are reliable proxies for historical and ecological mechanisms affected fish species distribution. Antropic disturbances of Amazonian rivers with distinct water colours could threaten unique fish assemblages.

It is now well established that algorithms are transforming our economy, institutions, social relations and ultimately our society. This paper explores the question – what is the role of law in the algorithmic society? We draw on the law-jobs theory of Karl Llewellyn and on William's Twining refinement of Llewellyn's work through the perspective of a thin functionalism to have a better understanding of what law does in this new context. We highlight the emergence of an algorithmic law, as law performs jobs such as the disposition of trouble-cases, the preventive channelling and reorientation of conduct and expectations, and the allocation of authority in the face of algorithmic systems. We conclude that the law-jobs theory remains relevant to understanding the role of law in the algorithmic society, but it is also challenged by how algorithms redefine who does or should do what law-jobs, and how they are done.

Topiramate (TOP) is a psychotropic drug prescribed for the treatment of epilepsy in children older than 2 years of age and for migraine prophylaxis in adolescents. There is evidence that TOP promotes negative effects on the reproductive system of male rats. This study aimed to evaluate the immediate and late treatment effects of TOP during childhood and adolescence on the male rat reproductive system. Two experimental groups received 41 mg/kg of TOP daily, by gavage, from postnatal day (PND) 16 to 28 (TOPc group) or from PND 28 to 50 (TOPa group). Control groups (CTRc group or CTRa group) received water daily. Half of the anim–als were evaluated 24 h after the end of treatment (PND 29 and PND 51, respectively) and the remainder were evaluated in adulthood (PND120). The following parameters were determined: anogenital distance, sperm evaluation, testis’ histomorphometry and plasma testosterone concentration. At PND 120, the volume (CTRc:62.58 ± 2.13; TOPc: 54.54 ± 2.10*%, p = 0.018) and total length (CTRc: 25.48 ± 1.61; TOPc: 18.94 ± 2.41*, p = 0.035) of seminiferous tubules were decreased and the volume of interstitial tissue (CTRc:37.41 ± 2.13; TOPc: 45.45 ± 2.09*%, p = 0.018) and number of Leydig cells/testis (CTRc: 277.00 ± 36.70; TOPc: 400.20 ± 13.23*, p = 0.013) were increased in the TOPc group. The other parameters remained similar between the groups. Therefore, the present study contributes to our understanding that childhood treatment with TOP has an impact on the rat reproductive system in adulthood, suggesting that this period is more sensitive to TOP exposure than adolescence.

The marketisation of disability support driven by individualised funding brings new dilemmas for multi-agency collaboration, in particular how to provide personalised supports while remaining commercially viable. This article explores the challenges, risks and adaptations of organisations to navigate the tensions of personalisation and collaboration. Framed by street-level research and using the context of Australia’s National Disability Insurance Scheme (NDIS), this article draws on interviews with twenty-eight organisational managers. Multi-agency challenges are highlighted when several providers are delivering parts of a NDIS participant’s plan, blurring organisational responsibilities and accountabilities. Interviews also revealed the paradox of organisational disconnection and organisational dependence concerning quality support provision and described the collaborative responses organisations implement to ensure their sustainability. There is commitment among organisations to build a trusted ecosystem of providers, but this is largely discretionary and there is a need for further policy mechanisms to enable organisations to negotiate a way through multi-agency dilemmas.

Peer victimization is a developmentally salient stressor that elevates adolescents’ risk for anxiety disorders. However, modifiable mechanisms that explain this link and can be targeted via therapeutic interventions remain poorly understood. Drawing from psychobiological models implicating aberrant threat sensitivity in the development and maintenance of psychopathology, the current study investigated sensitivity to peer-related social threats as a mechanism underlying the association between peer victimization and anxiety. A sample of 197 dyads of early adolescents (Mage = 12.02; 46% female) and parents/guardians (Mage = 41.46; 90% female) completed online surveys assessing peer victimization, sensitivity to potential (i.e., ambiguous) social threats, and anxiety. Controlling for potentially confounding demographic and psychosocial factors, both self- and parent-reported peer victimization were positively associated with adolescent anxiety symptoms. Additionally, there were significant indirect effects from self- and parent-reported peer victimization to anxiety via social threat sensitivity. Supplemental analyses indicated unique effects of covert, but not overt, peer victimization on social threat sensitivity and anxiety. The findings provide initial evidence that peer victimization experiences lower adolescents’ threshold for interpreting threats in ambiguous social situations, which contributes to heightened anxiety. These results implicate social threat sensitivity as a potential therapeutic target for interrupting links from peer victimization to psychological distress.

Our understanding of homogeneous vapour bubble growth is currently restricted to asymptotic descriptions of their limiting behaviour. While attempts have been made to incorporate both the inertial and thermal limits into bubble growth models, the early stages of bubble growth have not been captured. By accounting for both the changing inertial driving force and the thermal restriction to growth, we present an inertio-thermal model of homogeneous vapour bubble growth, capable of accurately capturing the evolution of a bubble from the nano- to the macro-scale. We compare our model predictions with: (a) published experimental and numerical data, and (b) our own molecular simulations, showing significant improvement over previous models. This has potential application in improving the performance of engineering devices, such as ultrasonic cleaning and microprocessor cooling, as well as in understanding of natural phenomena involving vapour bubble growth.

The article aims to identify the factors behind a series of center-left electoral victories in the 2002 and 2006 state elections, which indicate the decay of state political machines in Brazil's poorest regions. It is argued that vertical competition between the federal and state governments in the provision of public policies works as a constraint on state bosses' strategies of political control. The withering of state political machines may be understood as an indirect consequence of the national political shifts represented by the rise of Brazil's most important left-wing organization—the Workers' Party (Partido dos Trabalhadores)—to the presidency in 2002 and 2006. Social and economic policies implemented by the federal government under PT rule undermined subnational patron-client networks by improving the life conditions of the poorest sections of the electorate. The article explores the interlinking of national and subnational electoral dynamics by developing statistical models for state- and municipal-level data.

Brazil's constitution (1988) granted municipalities the responsibility of providing social services. Many observers anticipated that this newfound authority would produce policy diversity, as local governments would tailor programs to constituents' needs. Instead, many municipalities chose to replicate programs made famous elsewhere. What explains this diffusion of social policies across Brazil? In particular, what motivates policy makers to emulate “innovative” policies? This study compares three approaches that seek to explain political behavior: political self-interest, ideology, and socialized norms. It draws on two policies, Bolsa Escola, an education program, and Programa Saúde da Família, a family health program, in four exemplary cities, to uncover the mechanisms that led to diffusion. Surprisingly, political incentives, such as electoral competition, cannot explain diffusion. Rather, ideology and socialized norms, transmitted through social networks, drive policy emulation. Diffusion occurs when politicians are ideologically compelled to replicate these programs and when policy specialists seek to demonstrate that they follow professional norms.
