The Personalist Leadership Style of Fabio Vásquez: A Case Study on the Origins of the ELN

This article examines the personalist leadership style of Fabio Vásquez, a founding member of the Ejército de Liberación Nacional (ELN), the Colombian guerrilla group. Personalism, as a theoretical framework for understanding Latin American leaders, has primarily focused on traditional political practices, emphasizing the tensions and conflicts among formal institutions, political parties, and personalist politicians. While these studies provide valuable insights, they overlook leaders who operate outside conventional political structures who also rely on personalist strategies to attract and retain followers. This article seeks to bridge this gap by presenting a case study of Vásquez’s leadership style. In an era marked by the resurgence of populism and renewed interest in the effects of personalism on conventional politics, this article argues that examining personalist leadership within revolutionary insurgent groups that reject conventional party politics is necessary for a thorough understanding of the phenomenon. In particular, it offers a comprehensive overview of how Vásquez’s personalist strategies shaped the ELN’s early insurgency, ultimately revealing the strengths and vulnerabilities of such leadership within revolutionary movements.

Hormetic dose response induced by sublethal-dose sulfoxaflor leads to reproductive stimulation of Aphis gossypii

Aphis gossypii Glover is one of the most agriculturally important phloem-feeding economic pests, causing tremendous loss in crop yield annually. The hormesis is an important cause of A. gossypii resistance formation, population resurgence, and re-outbreak. However, whether the hormesises induced by different insecticides interact mutually remain largely unclear. In the study, four-generation A. gossypii experiment found that the 24-h sublethal-dose (LC20) sulfoxaflor treatment on G0 significantly increased the net reproductive rate (R0) and fecundity of G1 and G2 generation A. gossypii, but it did not significantly affect the fecundity of G3 and G4 individuals. Transcriptomic analyses revealed that the insecticide-induced significant up-regulation of pathways ribosome, energy metabolism, and the DNA replication and reparation might be responsible for the enhancement of fecundity in G1 and G2 A. gossypii. Notably, G0 exposure to LC20 sulfoxaflor followed by G1 exposure to LC30 deltamethrin resulted in a stronger reproductive stimulation than sulfoxaflor or deltamethrin exposure alone. Our findings provide valuable reference for optimizing sulfoxaflor application in integrated pest management strategies.

The low-lethal concentrations of rotenone and pyrethrins suppress the population growth of Rhopalosiphum padi

As an important pest on winter wheat, Rhopalosiphum padi (L.) causes damage to the wheat yield by sucking plant nutrients, transmitting plant viruses and producing mildew. R. padi has been reported to develop resistance to pyrethroids and neonicotinoids. To explore potential alternative approaches for R. padi control, the activity of 10 botanical insecticides was evaluated. Results suggested that the toxicity of rotenone and pyrethrins to R. padi were the highest and near to the commonly used chemical insecticides. When exposed to the low-lethal concentrations (LC10, LC30) of rotenone or pyrethrins for 24 h, the lifespan and fecundity of adults in F0 generation decreased significantly compared to control. The negative effect could also be observed in the F1 generation, including the decreased average offspring, longevity of adult, and prolonged nymph period. The population parameters in F1 generation of R. padi were also inhibited by exposing to the low-lethal concentrations of rotenone or pyrethrins, including the decreased net reproductive rate, intrinsic rate of natural increase, finite rate of population increase, and gross reproduction rate. Co-toxocity factor results showed that mixtures of rotenone and thiamethoxam, pyrethrins and thiamethoxam showed synergistic effect. Our work suggested that rotenone and pyrethrins showed negative effect on the population growth under low-lethal concentrations. They are suitable for R. padi control as foliar spraying without causing population resurgence.

Challenging the orthodoxy in international business research: Directions for “new” research areas

A strong critique of the international business field is that it has been “running out of steam” because IB scholars have failed to engage with emerging paradigm shifts in IB practice and management theory. IB research requires rejuvenation with timely, unique, controversial, and challenging new research questions. IB scholars need to move beyond incremental improvements to existing research agendas and focus on questions that are fundamentally new to the field. With this essay, we address four pressing topics (Buckley, Doh, & Benischke, 2017), namely: (1) the resurgence of populism, decoupling, and globalization; (2) disruptive technologies and digitalization; (3) sustainable development goals; and (4) the changing power relationships between firms, and between firms and governments. Our aim is to provide direct avenues for relevant new research that challenges the existing orthodoxy across the IB field. As part of this process, we introduce the papers in this special issue.

A study into the current state of Saiga tatarica L. populations with the use of retrospective data

The saiga antelope (Saiga tatarica tatarica L., 1766, S) is a prominent ungulate mammal species inhabiting Central Asia. Over the latter half of the 20th century, saiga populations, including the Volga-Ural (Kazakhstan) population, experienced a continuous decline. However, there was a resurgence in their numbers in the 1980s. This study aims to assess the present status of saiga populations, particularly the Volga-Ural (V-U) population, by analyzing existing retrospective data. Our findings reveal that during the 21st century, the saiga population has increased in two key regions: the Volga-Ural and Betpak-Dala (B) populations. Notably, the Northern-Western Population (NWP) habitat saw a drastic 50-fold decline in population, while other populations decreased by 2.0-5.0 times. Despite this decline, the NWP habitat exhibited higher juvenile saiga yields compared to other regions. The resurgence of saiga populations has been significantly influenced by the support of the Government of Kazakhstan, along with the effective efforts of international wildlife conservation organizations and local community engagement.

Reconsidering Photographic Temporality through Piotr Uklański’s Nazis

In The Nazis (1998) and its sequel, Real Nazis (2017), the Polish American artist Piotr Uklański creates glossy photographic assemblages of real and fictional Nazis, which critics have generally interpreted by turns as critiquing or participating in the culture industry’s fascination with and glamourization of Nazism. However, the formal mechanisms of Uklański’s work remain undertheorized. This essay offers a reading of The Nazis and Real Nazis that locates the aesthetic politics of these two products of the “perpetrator turn” in Holocaust studies and memory studies in the ways they manipulate assumptions about photographs’ temporality. Photographic theorists like Siegfried Kracauer, Susan Sontag, André Bazin, and Roland Barthes famously conceptualized photographic time through the category of grammatical tense and on examples of individual still images rather than photographic series. This essay builds on those theories by applying Peter Wollen’s work about narrative and grammatical aspect, which concerns the completedness or duration of what photographs depict, to argue that Uklański’s Nazi projects are more adequately explained as incomplete photographic narratives. By occluding viewers’ expectations about the aspect of photography, The Nazis and Real Nazis critically renarrate Nazism not as a completed historical trauma but as alive today amid a worldwide resurgence of right-wing populism.

“It’s All About US vs THEM!”: Comparing Chinese Populist Discourses on Weibo and Twitter

The recent resurgence of populism has led to renewed interest in the phenomenon, but it remains unclear how this phenomenon has manifested itself in non-Western settings like China. This article analyses Chinese populism and provides a systematic categorization of online discourses related to this phenomenon, including ideas about “the people,” “corrupt elites,” and “enemies.” The article is based on a collection of more than 100,000 Chinese online posts, collected from both Weibo and Twitter, that were classified as populist or not using natural language processing (NLP) models. We show how populism has manifested itself in Chinese online venues, and how populist discourses on Weibo and Twitter differ in topics, semantic content, and in who posts (agenda setters) and shares posts (audiences). The comparison demonstrates that different Chinese netizens take competing approaches to define the place of a rising China, and this also puts populism into the context of the peculiar Chinese way of rallying “the people” on behalf of the nation. Findings from this study contribute new insights into understanding populism in Chinese cyberspaces and provide a cross-platform perspective for understanding populist discourses in national and transnational contexts. The study also adds to computational methods in empirical research of populism in a comparative perspective.

Transgenerational effect of Afidopyropen on Bemisia tabaci Gennadius (Homoptera: Aleyrodidae)

Bemisia tabaci Gennadius (Homoptera: Aleyrodidae) is the most devastating insect-pest in cotton crop. It is vector of the cotton leaf curl virus (CLCV) and is responsible for huge losses to cotton industry in Pakistan and worldwide. It is mainly controlled by insecticides but the injudicious use of insecticides has resulted in insecticide resistance and population resurgence in addition to various harmful effects on the humans, non-target organisms and the environment. Transgenerational studies are very helpful to choose a best insecticidal option. In the current study, age-stage two-sex life table analysis was used to identify transgenerational effects of sublethal doses of afidopyropen. The adults of B. tabaci were treated with three concentrations of afidopyropen i.e., LC10, LC30 and LC50. The results indicated significant changes in the progeny i.e. the fecundity decreased in treated population; and female and male longevity of their progeny were more in control as compared to treated populations. Similarly, population parameters like intrinsic rate of growth (r), net reproductive rate (R0) and limiting rate of growth (λ) were significantly decreased in the treated adult progeny with values of 0.08–0.11, 4.85–7.46 and 1.09–1.12 per day, respectively. Based on the reduced biotic potential, afidopyropen can be suggested as an effective alternative option for the management of B. tabaci.

Uncovering the magnitude of African pangolin poaching with extensive nanopore DNA genotyping of seized scales.

Trade in pangolins is illegal, and yet tons of their scales and products are seized at various ports. These large seizures are challenging to process and comprehensively genotype for upstream provenance tracing and species identification for prosecution. We implemented a scalable DNA barcoding pipeline in which rapid DNA extraction and MinION sequencing were used to genotype a substantial proportion of pangolin scales subsampled from 2 record shipments seized in Singapore in 2019 (37.5t). We used reference sequences to match the scales to phylogeographical regions of origin. In total, we identified 2346 cytochrome b (cytb) barcodes of white-bellied (Phataginus tricuspis) (from 1091 scales), black-bellied (Phataginus tetradactyla) (227 scales), and giant (Smutsia gigantea) (1028 scales) pangolins. Haplotype diversity was higher for P. tricuspis scales (121 haplotypes, 66 novel) than that for P. tetradactyla (22 haplotypes, 15 novel) and S. gigantea (25 haplotypes, 21 novel) scales. Of the novel haplotypes, 74.2% were likely from western and west-central Africa, suggesting potential resurgence of poaching and newly exploited populations in these regions. Our results illustrate the utility of extensively subsampling large seizures and outline an efficient molecular approach for rapid genetic screening that should be accessible to most forensic laboratories and enforcement agencies.

Draining the Swamp? Populist leadership and corruption

AbstractThe resurgence of populism has presented a grave threat to democratic governance across the globe. Drawing on a cross‐national dataset of 155 countries from 1960 to 2020, we leverage the leadership turnovers within countries and use fixed effects models to estimate the effect of populist leadership on corruption. We find that populist leadership is associated with a substantial increase in executive corruption, but not other types of corruption. We also provide evidence that populist leaders are more likely to undermine judicial and legislative constraints, which in turn opens the door for massive executive corruption. We further show that whereas affluent resources exacerbate populist leaders' corruption, high‐quality bureaucracies, strong opposition parties, vigorous civil society organizations, and critical media work to mitigate the effect of populist leadership on corruption. This study contributes to the understanding of the nexus between populism and corruption and, more broadly, coping strategies for democratic backsliding.

Do young adults want to live downtown? Understanding attitudes in Prince George, BC

ABSTRACT Cities throughout North America are experiencing a population boom in the city centre, fueled by changing consumer preferences, particularly amongst young adults. However, not all communities have experienced this phenomenon equally. In Prince George, a mid-sized city located in northern British Columbia, the downtown has not undergone a population resurgence. Instead, development continues to expand outwards at the edge of the city. Using a web-based survey, this research seeks to better understand the attitudes of young adults in Prince George, to gauge their perspectives about living downtown, and to understand the factors that constrain market demand. Our findings indicate that respondents hold negative perceptions about the downtown, which leads to soft market demand and impedes plans for population growth in the downtown.

Populist strategies on Twitter: analysis of the political discourse during the campaign for the general elections in Spain on November 10th, 2019

In recent years we have witnessed a resurgence of populism, which has relied on the virality of social networks to deepen its roots in society and spread its ideas. This paper analyses the populist strategies used by all parties to viralise their messages in the online environment, regardless of ideology. The present research has also examined the possible existence of complementary strategies used by the parties’ organisational profiles and those of their leaders. To this end, a content analysis has been carried out regarding the publications made on Twitter during the 2019 election campaign. The posts have been delimited to those made by the parties and candidates that attained the highest percentage of representation in the Congress of Deputies, which include the PSOE, PP, Vox, and Unidas Podemos. The findings show that all the parties under study resorted to this type of strategy. The parties closest to centre of the political spectrum, both right and left, used mostly a populist strategy aimed predominantly at attacking their adversaries, while Vox and Unidas Podemos articulated their discourse beyond this argument, with Vox appealing to the emotions of the nation and Podemos positioning itself as the peoples’ advocate. Furthermore, a complementary strategy used by both the parties and their leaders has been identified, which fosters the expansion of these kinds of populist ideas.

Politicking Sikh identity: Memory, music, and mobilization in the Kisan Andolan

ABSTRACT Popular culture, though not apolitical, overlaps with overt political mobilisation, and vice versa. With the resurgence of populism, it is reaffirmed that politics has a propensity to co-opt popular culture, or, it often conflated itself with politics so that no separation exists. Are popular culture and political action co-constitutive? Using a deductive method as it explores the construction of ‘political activism’, foregrounding the popular culture as the axis of political mobilisation. It attempts to elucidate how Sikhs create their ‘political’ identities. The use of Music as explicitly ‘political’ and the adaptability of the ‘political’ youth in the times of ‘Hindutva’.

Constitutionalism, populism, and the imaginary of the authentic polity: a socio‐legal analysis of European public spheres and constitutional demoicratization

AbstractThe sociology of constitutionalism emphasizes the duality of constitutions as both power limitations and power enhancements. Following the socio‐legal perspective, this article focuses on the constitutional imaginary of the public sphere and distinguishes it from the imaginary of the authentic polity, in which the constituent power of the people is protected against the corrupting effect of representative institutions and technocratic bodies. The promise of authenticity is behind the recent resurgence of populism and the constitution of what Zygmunt Bauman describes as ‘explosive communities’. The final part of the article focuses on the transnational politics and law of the European Union (EU) and discusses its possible responses to the imaginaries of constitutional populism – most notably, the emergence of European public spheres and demoicracy. Without the constitutional imaginaries of an anti‐explosive transnational and democratically constituted community, further enhancement of the power of EU institutions will always lead to populist backlash at the national and local levels of its member states.

Ideologies and Utopia

In his most recent books, Piketty offers a global history of inequality in its economic, social, political, and intellectual dimensions, arguing that history is moved by the struggle of ideologies. To take part in this battle of ideas, he conceives a new ideal model of society, ‘participative socialism’, as an egalitarian alternative to the dominant neoproprietarian ideology and to the dangerous resurgence of nationalism and populism. This paper provides a new interpretation of Piketty’s view of history and of his participatory socialism in light of Paul Ricoeur’s study of the dialectics of ideology and utopia. First, I present Ricoeur’s singular analysis of ideology and utopia, which he sees as two inseparable facets of social imagination. Then I show how Ricoeur’s concepts can be fruitfully applied to Piketty’s conception of history and to his conception of a new form of socialism for the 21st century, drawing lessons from history and forming a ‘good’ or ‘realist’ utopia. Finally, I demonstrate that this interpretation of Piketty’s socialism can help to better understand some of the criticisms he has received.

Sublethal and transgenerational effects of pyridaben exposure on the fitness and gene expression of Panonychus citri.

Panonychus citri is a globally dominant citrus plant pest mite. Pesticide-induced population resurgence is a concern for mite control. Exposure to sublethal concentrations of pesticides has stimulated reproduction and outbreak risks in many pests. Pyridaben, a mitochondrial electron transport inhibitor, has been frequently used worldwide in mite control. In the study, sublethal and transgenerational effects of pyridaben exposure on Pyr_Rs (resistant) and Pyr_Control (susceptible) strains were systematically investigated in both exposed parental generation (F0 ) and unexposed offspring generations (F1 and F2 ) by evaluating life-table and physiological parameters. After exposure to pyridaben, the fecundity of both strains was significantly reduced in F0 generation while significantly induced in F1 generation. Interestingly, these effects also stimulated the fecundity of the F2 generation in Pyr_Control strain while no significant effects occurred for Pyr_Rs strain. The intrinsic rate of increase (r) and finite rate of increase (λ) were significantly decreased only in F1 generation of Pyr_Control strain after exposure treatment. Meanwhile, the population projection indicated a smaller population size in F1 generation of Pyr_Control strain while a population increase for Pyr_Rs strain after sublethal treatment. Subsequent detoxification enzyme assays indicated that only P450 activities in F0 generation were significantly activated by LC30 exposure to pyridaben in both strains. Significant downregulation of reproduction-related (Pc_Vg) genes was observed in the F0 generations of both strains. Significant upregulation of P450 (CYP4CL2) and PcVg of the F1 generation in both strains suggested the presence of delayed hormesis effects on the reproduction and developed tolerance to pyridaben, although the effects didn't last over a longer period (F2 generation). These results provide evidence for transgenerational hormesis effects of low concentrations of pyridaben exposure that may lead to population increase and resurgence risks of resistant-mites in natural settings by stimulating reproduction.

Mathematical Model of Basal Sprout Production in Vector-Borne Tree Disease

Some tree species respond to disease by producing basal sprouts from the base and root system of a dying tree, which can alter disease dynamics by altering demography. In the case of many lethal, airborne tree diseases, the production of basal sprouts can be a key contributor to population resurgence post-epidemic, but the effect in lethal, vector-borne tree diseases has not yet been studied. To determine the role of basal sprout production and secondary infection via the root system of infected parent trees in lethal, vector-borne tree diseases, we develop a stage-structured SI-X mathematical model and use laurel wilt, a vector-borne tree disease in which infected trees provide suitable material for vector reproduction, as our model system. The mathematical model shows that the production and secondary infection of basal sprouts do not affect the short-term dynamics of laurel wilt but profoundly alter the long-term dynamics of the laurel wilt epidemic. In particular, in the absence of basal sprout infection, basal sprout production yields a larger host population after disease establishment, but as secondary infection increases, the utility of basal sprouts to maintain the host population decreases. Results suggest management strategies for lethal, vector-borne diseases should depend on the ratio of the basal sprout production rate to the secondary infection rate.

Managing Wolves is Managing Narratives: Views of Wolves and Nature Shape People’s Proposals for Navigating Human-Wolf Relations

The resurgence of wolf populations in Germany is causing controversies regarding their management policies. Through 41 semi-structured interviews with stakeholders, we found that respondents favored the management directives predicated on the narratives they entertained, i.e., beliefs about wolves and nature more broadly. We identified 18 narratives that ranged from the extreme of “beings-focused, harmony-oriented, and wolf-favoring” extreme through “ecosystem-focused, conservation-oriented, and wolf-ambivalent” to another extreme of “human-centered, dominion-oriented, and wolf-critical” extreme. The 24 directives aim to allow, balance, and control wolf behavior. Narratives and directives correlate: participants and stakeholders holding beings-focused views tend to propose more allowing directives, those endorsing ecosystem-focused perspectives lean to choose balancing directives, and those inclined to human-focused stances prefer controlling directives. Thus, our research allows wildlife managers to understand better why people endorse or oppose specific management options and devise effective communication strategies by working with the underlying narratives.

Global Effect of Climate Change on Seasonal Cycles, Vector Population and Rising Challenges of Communicable Diseases: A Review

This article explains ongoing changes in global climate and their effect on the resurgence of vector and pathogen populations in various parts of the world. Today, major prevailing changes are the elevation of global temperature and accidental torrent rains, floods, droughts, and loss of productivity and food commodities. Due to the increase in water surface area and the longer presence of flood water, the breeding of insect vectors becomes very high; it is responsible for the emergence and re-emergence of so many communicable diseases. Due to the development of resistance to chemicals in insect pests, and pathogens and lack of control measures, communicable zoonotic diseases are remerging with high infectivity and mortality. This condition is becoming more alarming as the climate is favoring pathogen-host interactions and vector populations. Rapid changes seen in meteorology are promoting an unmanageable array of vector-borne infectious diseases, such as malaria, Japanese encephalitis, filarial, dengue, and leishmaniasis. Similarly, due to unhygienic conditions, poor sanitation, and infected ground and surface water outbreak of enteric infections such as cholera, vibriosis, and rotavirus is seen on the rise. In addition, parasitic infection ascariasis, fasciolosis, schistosomiasis, and dysentery cases are increasing. Today climate change is a major issue and challenge that needs timely quick solutions. Climate change is imposing non-adaptive forced human migration territorial conflicts, decreasing ecosystem productivity, disease outbreaks, and impelling unequal resource utilization. Rapid climate changes, parasites, pathogens, and vector populations are on the rise, which is making great threats to global health and the environment. This article highlighted the necessity to develop new strategies and control measures to cut down rising vector and pathogen populations in endemic areas. For finding quick solutions educational awareness, technology up-gradation, new vaccines, and safety measures have to be adopted to break the cycle of dreadful communicable diseases shortly.

The sublethal and transgenerational effects of pyridaben on fitness and induced tolerance in Panonychus citri

Panonychus citri is a dominant citrus pest mite in the world. Pesticide-induced population resurgence is a concern for environmental and resistance risk assessment in mite control. To evaluate the effective mite management strategies, the sublethal and transgenerational effects of pyridaben on P. citri were assessed using life-table parameters. Two segregated pyridaben-resistant and susceptible strains (previously obtained from the crossing between laboratory susceptible strain and pyridaben-resistant population) were used in our study. After exposure to LC30 pyridaben, the fecundity of Pyr_Control and Pyr_Rs strains were both significantly reduced in the parental generation (F0). Life-table results showed that LC30 pyridaben significantly induced the fecundity of both strains in F1 generation (egg stage was prolonged as well). Interestingly, this effect also stimulated the fecundity of F2 generation in Pyr_Control strain. But no significant effects were observed in Pyr_Rs strain. While detoxification enzyme assays indicated that only the activity of P450s was significantly activated by LC30 pyridaben in Pyr_Control and Pyr_Rs strains (1.242- fold and 1.355-fold increase, respectively). The expressions of P450 gene (CYP4CL2) and reproduction-related gene (Pc_Vg) were determined and the results showed that the expression of Pc_Vg of pyridaben treated mites in F0 generation was significantly reduced in both strains. In Pyr_Control and Pyr_Rs strains, the significant upregulation CYP4CL2 (2.029-fold and 2.516-fold increase, respectively) and PcVg (1.771-fold and 2.924-fold increase, respectively) of F1 generation suggested there were delayed hormesis effects on reproduction and developed tolerance to pyridaben. No significant difference was found between LC30 treatments and controls in F2 generation of both strains. These results provided evidence that transgenerational hormesis effects of low concentration of pyridaben might lead to mite population outbreak and resistance risk in the field through stimulating the reproduction and developing tolerance to pyridaben. Furthermore, LC30 pyridaben could affect the offspring populations of susceptible strain in the longer-term as compared to resistant strain.
