Moral Behaviour, Altruism and Environmental Policy

Free‐riding is often associated with self‐interested behaviour. However if there is a global mixed pollutant, free‐riding will arise if individuals calculate that their emissions are negligible relative to the total, so total emissions and hence any damage that they and others suffer will be unaffected by whatever consumption choice they make. In this context consumer behaviour and the optimal environmental tax are independent of the degree of altruism. For behaviour to change, individuals need to make their decisions in a different way. We propose a new theory of moral behaviour whereby individuals recognise that they will be worse off by not acting in their own self‐interest, and balance this cost off against the hypothetical moral value of adopting a Kantian form of behaviour, that is by calculating the consequences of their action by asking what would happen if everyone else acted in the same way as they did. We show that: (a) if individuals behave this way, then altruism matters and the greater the degree of altruism the more individuals cut back their consumption of a ’dirty’ good; (b) nevertheless the optimal environmental tax is exactly the same as that emerging from classical analysis where individuals act in self‐interested fashion.

A Comparison of the poverty impact of transfers, taxes and market income across five OECD Countries

This paper compares the poverty reduction impact of income sources, taxes and transfers across five OECD countries. Since the estimation of that impact can depend on the order in which the various income sources are introduced into the analysis, it is done by using the Shapley value. Estimates of the poverty reduction impact are presented in a normalized and un-normalized fashion, in order to take into into account the total as well as the per dollar impacts. The methodology is applied to data from the Luxembourg Income Study (LIS) database.

Are Dictators Immune to Human Rights Shaming?

This paper examines whether human rights naming and shaming destabilizes the rule of authoritarian leaders. We argue that human rights shaming can destabilize autocratic leaders by signaling international disapproval to elites in the targeted country, increasing their capacity to replace the incumbent. In personalist regimes, shaming increases the risk of irregular exit because regime elite do not have a means to peacefully replace the incumbent. Shaming campaigns also decrease foreign aid and international trade in personalist regimes, denying the leader access to resources to pay his coalition – further destabilizing his rule. In non-personalist regimes where parties or the military allow elites to peacefully replace incumbents, human rights shaming increases the risk of regular turnover of power, but has little effect on the risk of irregular exit or international flows of aid and trade. These findings have implications for understanding when and where shaming campaigns are likely to reduce or deter repression.

Plant tissue culture techniques

Plant cell and tissue culture in a simple fashion refers to techniques which utilize either single plant cells, groups of unorganized cells (callus) or organized tissues or organs put in culture, under controlled sterile conditions.

Estudi ambiental del Centre Esportiu Puigverd: aigua, residus i característiques físiques

El medi ambient està creixent i adquirint actualment una importància fins ara mai vista. La societat reconeix el medi ambient com un factor de benestar social i personal, i alhora una característica de modernitat. En aquest estudi s’analitzen tots els factors ambientals presents en l’activitat quotidiana d’un centre esportiu. El centre escollit es troba situat en el municipi de Castellar del Vallès, a la comarca del Vallès Occidental, província de Barcelona. Aquest centre construït fa 17 anys per la demanda continua dels habitants del poble i per les pressions dels nuclis urbans pròxims, ha sofert uns canvis que actualment encara estan presents. Els objectius de l’estudi són la descripció, l’anàlisi i el tractament de la gestió actual del centre envers els recursos utilitzats. L’aigua, els residus i per últim les propietats físiques de l’edificació, com a innovació en aquesta tipologia d’estudis. L’anàlisi i tractament d’aquests, permet conèixer els punts forts i febles del centre. Les flaqueses observades afecten majoritàriament als factors ambientals. Conseqüentment, es dissenyen unes propostes de millora per tal de poder minimitzar els impactes soferts i redireccionar la gestió ambiental del centre, afrontant així un futur amb un desenvolupament sostenible.

Plasmacytoid dendritic cells: one-trick ponies or workhorses of the immune system?

Plasmacytoid dendritic cells (pDCs) were first described as interferon-producing cells and, for many years, their overlapping characteristics with both lymphocytes and classical dendritic cells (cDCs) created confusion over their exact ontogeny. In this Viewpoint article, Nature Reviews Immunology asks five leaders in the field to discuss their thoughts on the development and functions of pDCs--do these cells serve mainly as a major source of type I interferons or do they also make other important contributions to immune responses?

Optimization and inhibition of the adherent ability of Plasmodium falciparum-infected erythrocytes

The vast majority of the 1-2 million malaria associated deaths that occur each year are due to anemia and cerebral malaria (the attachment of erythrocytes containing mature forms of Plasmodium falciparum to the endothelial cells that line the vascular beds of the brain). A "model" system"for the study of cerebral malaria employs amelanotic melanoma cells as the "target"cells in an vitro cytoadherence assay. Using this model system we determined that the optimum pH for adherence is 6.6 to 6.8, that high concentrations of Ca²* (50mM) result in increased levels of binding, and that the type of buffer used influences adherence (Bis Tris > MOPS > HEPES > PIPES). We also observed that the ability of infected erythrocytes to cytoadhere varied from (erythrocyte) donor to donor. We have produced murine monoclonal antibodies against P. falciparum-infected red cells which recognized modified forms of human band 3; these inhibit the adherence of infected erythrocytes to melanoma cells in a doso responsive fashion. Antimalarials (chloroquine, quinacrine, mefloquine, artemisinin), on the other hand, affected adherence in an indirect fashion i.e. since cytoadherence is due, in part to the presence of knobs on the surface of the infected erythrocyte, and knob formation is dependent on intracellular parasite growth, when plasmodial development is inhibited so is knob production, and consequently adherence is ablated.

Sialoglycoconjugates in Trypanosoma cruzi-host cell interaction: possible biological model - a review

A number of glycoconjugates, including glycolipids and glycoproteins, participate in the process of host-cell invasion by Trypanosoma cruzi and one of the most important carbohydrates involved on this interaction is sialic acid. It is known that parasite trans-sialidase participates with sialic acid in a coordinated fashion in the initial stages of invasion. Given the importance of these sialogycoconjugates, this review sets out various possible biological models for the interaction between the parasite and mammalian cells that possess a sialylated receptor/ligand system.

The Impact of democratization: a preliminary investigation on social policies and political violence in Latin America

The recent strides of democracy in Latin America have been associated to conflicting outcomes. The expectation that democracy would bring about peace and prosperity have been only partly satisfied. While political violence has been by and large eradicated from the sub-continent, poverty and social injustice still prevail and hold sway. Our study argues that democracy matters for inequality through the growing strength of center left and left parties and by making political leaders in general more responsive to the underprivileged. Furthermore, although the pension reforms recently enacted in the region generated overall regressive outcomes on income distribution, democratic countries still benefit from their political past: where democratic tradition was stronger, such outcomes have been milder. Democratic tradition and the specific ideological connotations of the parties in power, on the other hand, did not play an equally crucial role in securing lower levels of political violence: during the last wave of democratizations in Latin America, domestic peace was rather an outcome of political and social concessions to those in distress. In sum, together with other factors and especially economic ones, the reason why recent democratizations have provided domestic peace in most cases, but have been unable so far to solve the problem of poverty and inequality, is that democratic traditions in the subcontinent have been relatively weak and, more specifically, that this weakness has undermined the growth of left and progressive parties, acting as an obstacle to redistribution. Such weakness, on the other hand, has not prevented the drastic reduction of domestic political violence, since what mattered in this case was a combination of symbolic or material concessions and political agreements among powerful élites and counter-élites.

Sexual behaviour and stridulation during mating in Triatoma infestans (Hemiptera: Reduviidae)

Factors affecting mating behaviour in the bug Triatoma infestans were quantitatively studied in the laboratory. Experimental conditions were established so that the probability of copulation increased with the time elapsed since the first adult meal. Copulatory attempts by males did not vary as a function of time, but rejections by females became significantly less frequent with the post feeding time. Non-receptive females displayed four types of rejection behaviour, i.e. flattening, stridulation, evasion and abdominal movements. The occurrence of stridulation performed by females in a sexual context was observed in a regular fashion and was quantified for the first time in this species.

Fecal calprotectin more accurately reflects endoscopic activity of ulcerative colitis than the Lichtiger Index, CRP, or blood leukocytes

Background: Mucosal healing in ulcerative colitis (UC) is reported to be associated with favourable clinical outcomes such as reduced hospitalization and surgery rates. Activity monitoring by endoscopy has its shortcomings due to invasiveness, costs, and potential patient discomfort. Data on the correlation of noninvasive biomarkers with endoscopic severity in UC are scarce. Aim: to evaluate the correlation between endoscopic activity according to the modified Baron Index and fecal calprotectin, C-reactive protein (CRP), blood leukocytes, and the Lichtiger Index (clinical score). Methods: UC patients with leftsided and extensive colitis undergoing complete colonoscopy were prospectively enrolled and scored clinically and endoscopically. Fecal and blood samples were analyzed in UC patients (in a blinded fashion) and controls. The modified Baron score describes the following 5 endoscopic conditions: 0 = normal, 1 = granular mucosa, edema, 2 = friable mucosa but no spontaneous bleeding, 3 = microulcerations with spontaneous bleeding, 4 = gross ulceration, denuded mucosa. Results: We enrolled 228 UC patients (mean age 41 ± 13 years, 39 female) and 52 healthy controls. Disease was located in 40% in the left colon, 21% had an extensive and 39% a pancolitis. Endoscopic disease activity correlated best with fecal calprotectin (Spearman's rank correlation coefficient r = 0.821), followed by the Lichtiger Index (r = 0.682), CRP (r = 0.556), and blood leukocytes (r = 0.401). Fecal calprotectin was the only marker that could discriminate between different grades of endoscopic activity (grade 0, 25 ± 11 μg/g; grade 1, 44 ± 34 μg/g; grade 2, 111 ± 74 μg/g; grade 3, 330 ± 332 μg/g; grade 4, 659 ± 319 μg/g; P = 0.002 for discriminating grade 0 vs. 1, and P < 0.001 for discriminating grade 1 vs. 2, grade 2 vs. 3, and grade 3 vs. 4). Fecal calprotectin had the highest overall accuracy (91%) to detect endoscopically active disease (modified Baron Index ≥ 2), followed by the Lichtiger Index score of ≥ 4 (77%), CRP > 5 mg/L (69%) and blood leukocytosis (58%). Conclusions: Fecal calprotectin better correlated with endoscopic disease activity than clinical activity, CRP, and blood leukocytes. The strong correlation with endoscopic disease activity suggests that FC represents a useful biomarker for noninvasive monitoring of disease activity in UC patients.

Sacred Music, Sacred Journeys : What Makes an Event Postcolonial?

Fanon, Senghor, and Ela took a radical stance in criticising the structures and mechanisms of power in hegemonic situations and relations between colonial subjects and colonial masters. They aimed to liberate African societies by decolonising the mind, culture and religion of colonial subjects. In this respect, we are concerned with the continuities and ruptures of the colonial encounter and its unequal relationships. Switzerland does not have an official colonial history and yet, Swiss companies and migrants were and are part of the world's colonies. In our contribution, we question what makes an event postcolonial : in other words, how are postcolonial relations negotiated in Switzerland? We discuss this question by analysing two annual sacred journeys in Switzerland that have been invented for and by African Christians (clerics and laity) together with the leaders of the Swiss Catholic church : one to the relics of African saints in St. Maurice, canton Valais and the other to the Black Madonna, the Virgin Mary of Einsiedeln, in the canton Schwyz. These events are empowered by the performance of African choirs - their music, dance, and costumes - but to which end and in which way?

Three essays on leadership

ABSTRACT Samuel Bendahan, John Antonakis, Christian Zehnder, and François Pralong The relationship between power and immoral decisions has been discussed extensively by scientists and philosophers alike. Although the exercise of power is ubiquitous in social hierarchies, direct evidence on the impact of power on decision making is scarce. We use laboratory experiments to study whether more power leads to corruption. We manipulate power in the context of leader decision-making authority involving monetary stakes. Prior to the experiment, we also gathered extensive data on psychological and endocrinological individual differences. We find that an increase of power caused leaders to be more likely to engage in destructive, selfish behaviour, although the same subjects did not behave in this manner before their level of power was increased. We also show how individual differences affect the initial level of destructive behaviour and the corruption process. WHAT'S RIGHT FOR THE LEFT MAY NOT BE RIGHT FOR THE RIGHT: VALUE CONGRUENCE AND CHARISMA IN POLITICAL LEADERSHIP Samuel Bendahan ABSTRACT Value congruence between leaders and followers is important not only for follower commitment but also as part of the attributions followers make of leaders. I theorized that transformational leadership, which often is referred to as being value driven and having strong moral foundations, has differential effects depending on the values of the follower and whether these values are congruent with what the leader espouses. I designed an experiment to analyze how the political values of followers and leaders can influence followers' attributions regarding leaders. Within the context of political leadership, I found that transformational leaders were seen as more prototypical. Value congruence predicted prototypicality, which was strongly related to follower intentions to vote for the leader. Furthermore, followers with left-wing political values were more influenced by prototypical leaders than were followers with right-wing political values, presumably because of moral overtones of both left-wing ideology and transformational leadership. JUDGING LEADERSHIP POTENTIAL IN AN INTERVIEW: MODERATING EFFECT OF INTERVIEWER INTELLIGENCE ON INTERVIEWER COGNITIVE BUSYNESS, CANDIDATE PERFORMANCE-CUES EFFECTS, AND CANDIDATE ETHNICITY Samuel Bendahan, Philippe Jacquart, and John Antonakis ABSTRACT A large body of literature suggests that interviewers do not accurately rate candidates when using unstructured interviews and evaluation procedures that affect pre-interview expectations; however, the process by which these biases are produced is not well understood. We theorized several reasons for the sub-par performance of the unstructured interview. These factors, which we manipulated in the context of a videotaped interview of a candidate applying for a leadership position, include evaluator cognitive load, pre-interview performance cues regarding the candidate, and the ethnicity of the candidate. We also controlled for the intelligence of the evaluator. We found a significant four-way interaction between the manipulated factors and evaluators' cognitive abilities. The effects of the manipulated factors were all significantly less for evaluators who were high on general intelligence.

L'image de la Suisse à l'étranger

L'image qu'un pays a dans le monde est importante à plusieurs titres. Elle peut soutenir la commercialisation de biens et de services exportés, elle revêt un caractère tout particulier dans le cadre des promotions touristique et économique et elle peut aussi être de nature à contribuer aux relations qu'un pays entretient avec d'autres pays aux niveaux politique, économique ou culturel. L'image de la Suisse a fait l'objet d'études dans de nombreux pays, dont les Etats-Unis, l'Allemagne et la Chine, auprès d'échantillons représentatifs de la population ainsi qu'auprès de groupes de leaders d'opinion et cet ouvrage présente de manière synthétique les principaux résultats de ces études. Après une description de l'image globale de la Suisse auprès des personnes interrogées et une analyse des associations faites à l'évocation de la Suisse, une partie importante est consacrée aux dimensions qui caractérisent l'image du pays en différenciant notamment entre les dimensions liées à la Suisse en tant qu'espace socioculturel et les dimensions liées aux aspects économiques. Pour terminer, un dernier chapitre analyse l'impact de faits ayant marqué l'actualité helvétique, comme le grounding de Swissair, sur l'image de la Suisse dans les pays étudiés.

Fifteen years of molecular lymphangiogenesis - an interview with Kari Alitalo by Tatiana Petrova.

Kari Alitalo is one of the leaders in the field of lymphangiogenesis. Research from his laboratory has contributed to the transformation of a largely descriptive field into a dynamic discipline, which now holds promise for the treatment of cancer, inflammation and vascular dysfunction. The interview intends to provide historical insights into these changes and hopefully inspiration to the young generation of vascular biologists.
