Are radical right-wing parties the black holes in party space? Implications and limitations in impact assessment of radical right-wing parties

Radical right-wing parties have been a constant force in party systems of Western Europe since the late 1980s, despite cycles of development and support. Still, measurement of their impact has proven difficult. Scholars assessing the impact of radical right-wing parties in recent years have produced mixed findings in terms of whether effects tend to be direct or indirect and more or less salient. The recent book by Carvalho engages existing literature on impact assessment examining the cases of the UK, France and Italy. His findings caution against overstatement of impacts on immigration policy, suggesting that effects are contingent on party system competition and mainstream party agency. This article considers the mixed results pointing to a lack of existing tools for measuring indirect party impacts. It contends that existing theory on party impact struggles to conceptualize empty spaces in political ideology, attributing agency to moving parties and not to others that may be pushing them.     

Food Supply and Chimpanzee (Pan troglodytes schweinfurthii) Party Size in the Budongo Forest Reserve,Uganda

A central issue in socioecology is the nature of the relationship between an organism's environment and its social structure. In chimpanzees, the fission-fusion social system is thought to minimize feeding competition for primary dietary components: ephemeral, dispersed patches of ripe fruit. Intragroup feeding competition is thought to force individuals into small parties. Informal observations in the Sonso region of the Budongo forest had suggested that in this habitat, food supply was such that feeding competition was less important in determining grouping patterns than elsewhere. We used data collected on food supply and party sizes over a 4-year period to investigate this suggestion. In accord with theoretical expectation, sizes of foraging parties fluctuated with the size of food patches. However, party sizes showed either negative or no relationship with habitat-wide measures of food abundance. Likewise party sizes showed little relationship to overall measures of food dispersion. For important dietary items, both fruit and leaves had patchy distributions, though the degree of clumping was not strong, and fruit was not more clumped than leaves. Generally, abundant food appeared to be less patchy, and chimpanzees appeared to use more patches as food became more abundant rather than forming larger parties. We suggest that both dispersal and abundance need to be considered when investigating the impact of food supply on grouping patterns, and that the importance of food as a factor in determining chimpanzee grouping patterns declines with increasing levels of abundance.     

The political and policy impacts of extreme right parties in time and context

Impact of Extreme Right Parties makes a welcome contribution to the growing scholarship that assesses the impacts of extreme right parties (ERPs) on inter-party competition, public opinion and public policy. Although it commendably avoids the pitfall of overestimating the political significance of ERPs, several criticisms of the book nevertheless can be raised. First, it is disquieting that its analysis of the impacts of ERPs within its chosen three countries covers less than a decade. Second, the reader may come away questioning its ultimate contribution to our understanding of the staying power of ERPs. Third, it is reasonable to ask if in investigating the impacts of ERPs on inter-party competition and public opinion the book is simply accumulating evidence for the much more important question of their impact on public policy. Finally, it is unfortunate that the possible effects of ERPs on partisan and party system dealignment are not considered.     

Partner choice creates fairness in humans

Many studies demonstrate that partner choice has played an important role in the evolution of human cooperation, but little work has tested its impact on the evolution of human fairness. In experiments involving divisions of money, people become either over-generous or over-selfish when they are in competition to be chosen as cooperative partners. Hence, it is difficult to see how partner choice could result in the evolution of fair, equal divisions. Here, we show that this puzzle can be solved if we consider the outside options on which partner choice operates. We conduct a behavioural experiment, run agent-based simulations and analyse a game-theoretic model to understand how outside options affect partner choice and fairness. All support the conclusion that partner choice leads to fairness only when individuals have equal outside options. We discuss how this condition has been met in our evolutionary history, and the implications of these findings for our understanding of other aspects of fairness less specific than preferences for equal divisions of resources.     

Grouping behavior of Sumatran orangutans (Pongo abelii) and Tapanuli orangutans (Pongo tapanuliensis) living in forest with low fruit abundance

In contrast to the African great apes, orangutans (Pongo spp.) are semisolitary: Individuals are often on their own, but form aggregations more often than expected by chance. These temporary aggregations provide social benefits such as mating opportunities. When fruit availability is high, costs of aggregating should be lower, because competition is less pronounced. Therefore, average party size is expected to be higher when fruit availability is high. This hypothesis would also explain why orangutans in highly fruit-productive habitats on Sumatra are more gregarious than in the usually less productive habitats of Borneo. Here, we describe the aggregation behavior of orangutans in less productive Sumatran habitats (Sikundur and Batang Toru), and compare results with those of previously surveyed field sites. Orangutans in Sikundur were more likely to form parties when fruit availability was higher, but the size of daily parties was not significantly affected by fruit availability. With regard to between-site comparisons, average party sizes of females and alone time of parous females in Sikundur and Batang Toru were substantially lower than those for two previously surveyed Sumatran sites, and both fall in the range of values for Bornean sites. Our results indicate that the assessment of orangutans on Sumatra as being more social than those on Borneo needs revision. Instead, between-site differences in sociality seem to reflect differences in average fruit availability.     

Reducing the gap between leaders and voters? Elite polarization,outbidding competition,and the rise of secessionism in Catalonia

The ethnic outbidding thesis explains party polarization as a consequence of political changes amongst voters. We argued instead that party elites’ extreme position on the national identity cleavage can help polarizing strategies to prevail over moderate strategies in a context of increasing political uncertainty, without previous voters’ polarization. We test successfully this hypothesis in Catalonia by analysing the polarization of political parties and people’s demands for self-government in Catalonia since the early 2000s. We also find that the result of this outbidding pattern of competition was a reduction in the gap between elites’ and voters’ views on national identity. The analysis employs a set of unique data on party elites and activists’ national identity, from several surveys conducted on the delegates at party conferences of the main Catalan parties between 1996 and 2012. Our data provide empirical support for the argument that ethnic polarization is mainly an elite-driven process.     

Who's invited to the (political) party: race and party politics in the USA

ABSTRACT

From the political behemoths of the Democratic and Republican Parties, to the Civil Rights Era racially progressive Mississippi Freedom Democratic Party and reactionary American Independent Party, to the contemporary third party Green and Libertarian Parties, party politics in the USA has a long and storied relationship to the reproduction and contestation of racial domination. Recent works illuminate the strategic use of racial discourse by major party political elites, their deployment of racialized political platforms, and the relationship of these phenomena to power dynamics and racial interests but have yet to fully move beyond the two-party system and engage with innovations in political and cultural sociology. We outline openings for an empirically-grounded sociology of political parties that would reveal the micro- and meso-level features of racialized party politics and the operations of discursive and performative power within both major and minor political parties.     

Influence of Seasonality on Activity Patterns, Feeding Behavior, Ranging, and Grouping Patterns in Taï Chimpanzees

Lowland rain forest chimpanzees (Pan troglodytes verus) of the Taï National Park, Ivory Coast, responded to the minor dry season (July and August) of 1988 in a predictable manner by spending more time feeding, feeding more frequently on lower quality food items, reducing day range and party size, and spending more time solitarily and less time in mixed groups than during the rainy season. These behaviors are consistent with a response to scarce resources. My findings do not support Boesch's (1991, 1996) hypothesis of bisexually bonded chimpanzees. Females spent 45% of time alone and associated with males in mixed parties only 18% of their time. This major discrepancy in our results probably stems from differences in the time of year when our studies were conducted, the year in which my study was conducted (potentially scarcer resources than on average), and methodological differences: focal animal sampling of males and females equally. Although Boesch (1991, 1996) and Steiner (1996) have demonstrated that Taï parties are usually larger and more mixed, Taï chimpanzee social structure—party size and composition—during this study closely resembles that found at other study sites.     

Maternal rank and local resource competition do not predict birth sex ratios in wild baboons

We test two models of adaptive adjustment of birth sex ratios that are expected to apply to Cercopithecine primate species. It has been predicted that when maternal investment differentially influences the reproductive success of male and female offspring, females in good condition will bias investment in favour of the sex that gains the greatest fitness returns from additional investment. This hypothesis was subsequently amended to take into account the effects of local resource competition on maternal investment strategies of primate females. This body of theory has been applied to primates with contradictory results, prompting some to question the conclusion that primate females facultatively adjust birth sex ratios in an adaptive manner. Here, we present a meta-analysis of the relationship between maternal rank, birth sex ratios and local resource competition in 36 groups of wild savannah baboons, Papio cynocephalus. The results do not support predictions derived from either model of facultative sex ratio adjustment, and we conclude that there is currently no evidence that baboon birth sex ratios are adjusted in an adaptive manner.     

Party composition and dynamics inPan paniscus

The pygmy chimpanzee, or bonobo, Pan paniscus,diplays a fission-fusion social organization in which individuals associate in parties that vary in size and composition. Data from a 2-year field study of nonprovisioned P. paniscusshow that party composition varies with party size. Although females, on average, outnumber males, the proportion of males in the party increases in larger parties. This effect was not due to the greater number of known females. Both females and males will join and leave a party in the company of others, but only males appear frequently to join or leave as lone individuals. All-male parties were not observed, but all-female (nonnursery) parties were relatively common. These trends reflect greater cohesion among females than observed in P. troglodytes schweinfurthii.Cohesion between males and female P. paniscusmay increase with party size.     

Ethnic exclusionism in the periphery: The case of Oriental Jews in Israel's development towns

Students of Israeli politics have stressed cultural factors in explaining the success of right‐wing parties among Oriental Jewish voters. My argument is that closer attention must be paid to labour market relations in trying to explain both the anti‐Arab sentiments of Oriental Jews and their proclivity for right‐wing politics.

Oriental Jews compete with both citizen and non‐citizen Palestinians for jobs at the lowest end of the occupational ladder. This competition, I argue, can explain a great deal of their political attitudes. The data to support the argument are derived from an attitude survey conducted in 1988 in eight ‘development towns’ ‐ small working‐class communities populated mainly with Orientals and characterized by high unemployment rates and pervasive social and economic ills. These towns, and the sociologically similar slum neighbourhoods of major cities, provided Rabbi Meir Kahane, Israel's most vociferously racist politician, with the bulk of his electoral support when he was elected to the Knesset in 1984. In 1988 I found support for Kahane in development towns was almost three times as high as it was in 1984. (Kahane was barred from running for the Knesset in 1988 for being a racist.) Analysis of the data showed that this support was disproportionately concentrated among respondents who suffered most from the effects of labour market friction with Palestinian workers.     

Changes in pornography-seeking behaviors following political elections: an examination of the challenge hypothesis

The current study examined whether or not individuals who vicariously win a competition seek out pornography relatively more often than individuals who vicariously lose a competition. By examining a portion of Google keyword searches during the 2004, 2006 and 2008 US election cycles, the relative popularity of online pornography keywords searches was computed for each state and the District of Columbia the week before and the week after each election. Consistent with the Challenge Hypothesis, following all three election cycles, individuals located in states voting for the winning political party tended to search for pornography keywords relatively more often than individuals residing in states voting for the losing political party.     

Coalition formation among male Barbary macaques (Macaca sylvanus)

A coalition is formed when one animal intervenes in an ongoing conflict between two parties to support one side. Since support of one party is also an act against the other party, coalitions are triadic interactions involving a supporter, a recipient, and a target. The purpose of this study was to test which of three possible theories explains coalition formation among male Barbary macaques: 1) Males support kin to enhance their indirect fitness (kin selection). 2) Males support nonkin to receive future reciprocal support (reciprocal altruism). 3) Males pursue self-interests and immediately benefit via nonkin support (cooperation). Coalition formation was investigated among 31 semi-free male Barbary macaques in the Salem Monkey Park, Germany during the mating season. The results show: 1) Males intervened more often in dyadic conflicts in which a related opponent was involved and supported related opponents more than unrelated opponents. Close kin supported each other more often than distant kin. 2) Some evidence for reciprocal support was found. However, reciprocity was probably a by-product of targeting the same individuals for dominance. 3) Coalition formation among nonkin is best interpreted as cooperation, based on self-interests. Male Barbary macaques seem to intervene more often to stabilize and less often to improve their rank. Although our data were limited, the results revealed that kin support, reciprocal support, and cooperative support were all involved in coalition formation among male Barbary macaques.     

Urinary C-peptide levels in male bonobos (Pan paniscus) are related to party size and rank but not to mate competition

Within- and between-species variation in male mating strategies has been attributed to a multitude of factors including male competitive ability and the distribution of fertile females across space and time. Differences in energy balance across and within males allow for the identification of some of the trade-offs associated with certain social and mating strategies. Bonobos live in groups with a high degree of fission–fusion dynamics, there is co-dominance between the sexes and a linear dominance hierarchy among males. Males compete over access to females, breeding is aseasonal, and females exhibit sexual swellings over extended time periods. In this study we use urinary C-peptide (UCP) levels in male bonobos (Pan paniscus) obtained from 260 urine samples from a wild bonobo community, to quantify male energy balance during mate competition and levels of gregariousness in the species. Although high ranking males are more aggressive, spend more time in proximity to maximally tumescent females, and have higher mating frequencies, we found no indication that mate guarding or mate competition affected male energy balance. Our results showed a positive correlation between monthly mean UCP levels and mean party size. When traveling in large parties, high ranking males had higher UCP levels than those of the low ranking males. These results support the hypothesis that patterns of fission–fusion dynamics in bonobos are either linked to energy availability in the environment or to the energetic costs of foraging. The finding of a rank-bias in UCP levels in larger parties could also reflect an increase in contest competition among males over access to food.     

Sex-ratio variation and reproductive costs in relation to density in a forest-dwelling population of red deer (Cervus elaphus)

For dimorphic species in which the variance in reproductivesuccess of males is more pronounced than that of females, theoriesof adaptive variation in sex ratio predict that mothers shouldinvest more heavily in sons than in daughters. By using harvestdata from a forest-dwelling red deer population that experienceda marked reduction in population density we tested the hypothesisthat adaptive sex-ratio variation should occur only when populationsare much below carrying capacity. More specifically, we testedwhether at low density, females in better than average conditionwere more likely to produce male offspring and to invest inindividual sons rather than were females in poorer than averagecondition. We also investigated female reproductive costs arisingfrom a decrease either in body mass or in reproduction. We didnot find any support for a biased sex ratio or investment towardmale calves by high-quality mothers at any population density.Costs of reproduction in terms of body mass and pregnancy rateswere only detectable for females that reproduced as yearlingsand not for those that reproduced as adults. Our results thereforedo not support the hypothesis of adaptive sex-ratio variationin a population living below carrying capacity. The four-folddifference in party sizes (defined as the number of deer aggregatein the same party in which no individual was more than 50 mfrom any other) observed in our population living in a closedforest habitat compared with populations living in more openhabitats previously studied might account for such a discrepancy.We suggest that a smaller party size may decrease the intensityof sexual selection and could be the proximal cause for thelack of adaptive sex-ratio variation we report for the populationstudied here.     

Mahale chimpanzees: grouping patterns and cycling females

The social system of chimpanzees (Pan troglodytes schweinfurthii) is characterized by the fission-fusion of social groups. Several studies have reported that females are less gregarious than males. In the current study, adult female gregariousness depended on their reproductive state. Noncycling adult females (pregnant, lactating, or post reproductive) were observed in large bisexual parties less often than cycling adult females. On the other hand, cycling adult females were observed in large bisexual parties as often as males, regardless of their estrous state. More males were in parties that included cycling adult females with maximal genital swelling (estrous females) than in parties without them. Moreover, a bisexual party including more estrous females contained more males. These results suggest that large bisexual parties of chimpanzees are constructed by a dual mechanism. First, cycling adult females are attracted to parties that consist of the top ranking male and large numbers of adult and adolescent males. Second, adult and adolescent males that did not belong to parties originally are attracted by estrous females and join them. Thus, in Mahale Mountains National Park, Tanzania, bisexual parties of chimpanzees can be characterized as "parties for reproduction."     

Long‐term evolutionary conflict,Sisyphean arms races,and power in Fisher's geometric model

Evolutionary conflict and arms races are important drivers of evolution in nature. During arms races, new abilities in one party select for counterabilities in the second party. This process can repeat and lead to successive fixations of novel mutations, without a long‐term increase in fitness. Models of co‐evolution rarely address successive fixations, and one of the main models that use successive fixations—Fisher's geometric model—does not address co‐evolution. We address this gap by expanding Fisher's geometric model to the evolution of joint phenotypes that are affected by two parties, such as probability of infection of a host by a pathogen. The model confirms important intuitions and offers some new insights. Conflict can lead to long‐term Sisyphean arms races, where parties continue to climb toward their fitness peaks, but are dragged back down by their opponents. This results in far more adaptive evolution compared to the standard geometric model. It also results in fixation of mutations of larger effect, with the important implication that the common modeling assumption of small mutations will apply less often under conflict. Even in comparison with random abiotic change of the same magnitude, evolution under conflict results in greater distances from the optimum, lower fitness, and more fixations, but surprisingly, not larger fixed mutations. We also show how asymmetries in selection strength, mutation size, and mutation input allow one party to win over another. However, winning abilities come with diminishing returns, helping to keep weaker parties in the game.     

Party competition and the production of nationhood in the immigration context: particularizing the universal for political gain in France and Québec

Analysing parties’ media representations in the context of France’s 2010 legal ban of Islamic facial coverings and Québec’s (rejected) Charter of Values in 2013, this paper foregrounds the neglected role that party competition plays in shaping the construction of nationhood in public debates around immigrant religious practices. Our findings show that in these debates, political parties aim to maintain their distinct identities by generating a particular universalism, in which purportedly “universal” values, such as gender equality, are imbricated with particularistic images of nationhood.     

Seasonal variation in association patterns of wild spider monkeys (<Emphasis Type="Italic">Ateles belzebuth belzebuth</Emphasis>) at La Macarena,Colombia

Spider monkeys exhibit a fission–fusion type of social organization. I studied party size and party composition in wild long-haired spider monkeys (Ateles belzebuth belzebuth) in three study periods at La Macarena, Colombia and found that overall party size was larger in the fruit-abundant season. Mean party size in which males were observed was relatively stable across seasons. In contrast, the mean party size of females varied. Females were observed in larger parties in the fruit-abundant season than in the fruit-scarce season. Moreover, whereas males associated with each other at an almost equal frequency across seasons, females associated with each other more frequently in the fruit-abundant season. Females with infants or small juveniles were more often in association with other individuals than were cycling females. The intensity of individual relationships varied according to season, such that even mothers and sons were not always strongly associated. In a large party, females with infants may gain from predation avoidance but they are at a disadvantage in terms of scramble competition. The balance between these factors may change with fruit availability and may influence party size in different periods. For males, party formation may facilitate the defense of resources from neighboring groups more than provide predation avoidance. Electronic Publication     

The role of behavioral dynamics in determining the patch distributions of interacting species

The effect of the behavioral dynamics of movement on the population dynamics of interacting species in multipatch systems is studied. The behavioral dynamics of habitat choice used in a range of previous models are reviewed. There is very limited empirical evidence for distinguishing between these different models, but they differ in important ways, and many lack properties that would guarantee stability of an ideal free distribution in a single-species system. The importance of finding out more about movement dynamics in multispecies systems is shown by an analysis of the effect of movement rules on the dynamics of a particular two-species-two-patch model of competition, where the population dynamical equilibrium in the absence of movement is often not a behavioral equilibrium in the presence of adaptive movement. The population dynamics of this system are explored for several different movement rules and different parameter values, producing a variety of outcomes. Other systems of interacting species that may lack a dynamically stable distribution among patches are discussed, and it is argued that such systems are not rare. The sensitivity of community properties to individual movement behavior in this and earlier studies argues that there is a great need for empirical investigation to determine the applicability of different models of the behavioral dynamics of habitat selection.
