Federalism and the Concept of Political Territoriality: Towards an Analytical Framework for Comparative Territorial Politics

The core issues comparative territorial politics addresses are how and why territory is used to delimit, maintain, or create political power; and with what kind of consequences for efficiency (output) and legitimacy (input). The aim of this article is to integrate various research strands into the comparative study of territorial politics, with federal studies at its core. As an example of a conceptual payoff, ‘political territoriality’ refers the observer to three dimensions of the strategic use of areal boundaries for political power. By focusing on territory as a key variable of political systems, the actors, processes and institutions are first analytically separated and continuously measured, enhancing internal validity, and then theoretically integrated, which allows more valid external inferences than classic, legal-institutionalist federal studies. After discussing the boundaries and substance of comparative territorial politics as a federal discipline, political territoriality is developed towards an analytical framework applicable to politics at any governmental level. The claims are modest: political territoriality does not serve so much as an explanatory concept as rather an ‘attention-directing device’ for federal studies.

Eco-Evolutionary Spatial Dynamics. Rapid Evolution and Isolation Explain Food Web Persistence

One of the current challenges in evolutionary ecology is understanding the long-term persistence of contemporary-evolving predator–prey interactions across space and time. To address this, we developed an extension of a multi-locus, multi-trait eco-evolutionary individual-based model that incorporates several interacting species in explicit landscapes. We simulated eco-evolutionary dynamics of multiple species food webs with different degrees of connectance across soil-moisture islands. A broad set of parameter combinations led to the local extinction of species, but some species persisted, and this was associated with (1) high connectance and omnivory and (2) ongoing evolution, due to multi-trait genetic variability of the embedded species. Furthermore, persistence was highest at intermediate island distances, likely because of a balance between predation-induced extinction (strongest at short island distances) and the coupling of island diversity by top predators, which by travelling among islands exert global top-down control of biodiversity. In the simulations with high genetic variation, we also found widespread trait evolutionary changes indicative of eco-evolutionary dynamics. We discuss how the ever-increasing computing power and high-resolution data availability will soon allow researchers to start bridging the in vivo–in silico gap.

Structural and Institutional Determinants of Influence Reputation: A Comparison of Collaborative and Adversarial Policy Networks in Decision Making and Implementation

The central assumption in the literature on collaborative networks and policy networks is that political outcomes are affected by a variety of state and nonstate actors. Some of these actors are more powerful than others and can therefore have a considerable effect on decision making. In this article, we seek to provide a structural and institutional explanation for these power differentials in policy networks and support the explanation with empirical evidence. We use a dyadic measure of influence reputation as a proxy for power, and posit that influence reputation over the political outcome is related to vertical integration into the political system by means of formal decision-making authority, and to horizontal integration by means of being well embedded into the policy network. Hence, we argue that actors are perceived as influential because of two complementary factors: (a) their institutional roles and (b) their structural positions in the policy network. Based on temporal and cross-sectional exponential random graph models, we compare five cases about climate, telecommunications, flood prevention, and toxic chemicals politics in Switzerland and Germany. The five networks cover national and local networks at different stages of the policy cycle. The results confirm that institutional and structural drivers seem to have a crucial impact on how an actor is perceived in decision making and implementation and, therefore, their ability to significantly shape outputs and service delivery.

Europeanization in parliament and in the press

Europeanization challenges national democratic systems. As part and parcel of the broader internationalization of politics, Europeanization is associated with a shift from policymaking within majoritarian, elected representative bodies towards technocratic decisions among non-majoritarian and non-elected bodies (Kohler-Koch and Rittberger 2008, Lavenex 2013). It is thus said to weaken the influence of citizens and parliaments on the making of policies and to undermine democratic collective identity (Lavenex 2013, Schimmelfennig 2010). The weakening of national parliaments has been referred to as “de-parliamentarisation” (Goetz and Meyer-Sahling 2008) and has nurtured a broader debate regarding the democratic deficit in the EU. While not being a member of the EU, Switzerland has not remained unaffected by these changes. As discussed in the contribution by Fischer and Sciarini, state executive actors take the lead in Switzerland's European policy. They are responsible for the conduct of international negotiations, they own the treaty making power, and it is up to them to decide whether they wish to launch a negotiation with the EU. In addition, the strong take-it or leave-it character of Europeanized acts limits the room for manoeuver of the parliamentary body also in the ratification phase. Among the public, the rejection of the treaty on the European constitution has definitely closed the era of “permissive consensus” (Hooghe and Marks 2009). However, the process of European unification remains far remote from the European public. In Switzerland, the strongly administrative character of international legislation hinders public discussion (Vögeli 2007). In such a context, the media may serve as cue for the public: By delivering information about the extent and nature of Europeanized policymaking, the media enable citizens to form their own opinions and to hold their representatives accountable. In this sense media coverage may not only be considered an indicator of the information delivered to the public, but it may also enhance the democratic legitimacy of Europeanized policymaking (for a similar argument, see Tresch and Jochum 2005). While the previous contributions to this debate have examined the Europeanization of Swiss (primary and secondary) legislation, we take a closer look at two additional domestic arenas that are both supposed to be under pressure due to Europeanization: The parliament and the media. To that end, we rely on data gathered in a research project that two of us carried out in the context of the NCCR Democracy.1 While this project was primarily interested in the mediatization of decision-making processes in Switzerland, it also investigated the conditional role played by internationalization/Europeanization. For our present purposes, we shall exploit the two data-sets that were developed as part of a study of the political agenda-setting power of the media (Sciarini and Tresch 2012, 2013, Tresch et al. 2013): A data-set on issue attention in parliamentary interventions (initiatives, motions, postulates,2 interpellations and questions) and a data-set on issue attention in articles from the Neue Zürcher Zeitung (NZZ). The data covers the years 1995 to 2003 and the coding of issues followed the classification system developed in the “Policy Agendas Project” (Baumgartner and Jones 1993).

Ethnography of a Land-Deal. Local Perceptions and Vertical Perspectives of a Large Scale Land Acquisition Project in Northern Sierra Leone

Despite an increased scientific interest in the relatively new phenomenon of large-scale land acquisition (LSLA), data on processes on the local level remain sparse and superficial. However, knowledge about the concrete implementation of LSLA projects and the different impacts they have on the heterogeneous group of project affected people is indispensable for a deepened understanding of the phenomenon. In order to address this research gap, a team of two anthropologists and a human geographer conducted in-depth fieldwork on the LSLA project of Swiss based Addax Bioenergy in Sierra Leone. After the devastating civil war, the Sierra Leonean government created favourable conditions for foreign investors willing to lease large areas of land and to bring “development” to the country. Being one of the numerous investing companies, Addax Bioenergy has leased 57’000 hectares of land to develop a sugarcane plantation and an ethanol factory to produce biofuel for the export to the European market. Based on participatory observation, qualitative interview techniques and a network analysis, the research team aimed a) at identifying the different actors that were necessary for the implementation of this project on a vertical level and b) exploring various impacts of the project in the local context of two villages on a horizontal level. The network analysis reveals a complex pattern of companies, institutions, nongovernmental organisations and prominent personalities acting within a shifting technological and discursive framework linking global scales to a unique local context. Findings from the latter indicate that affected people initially welcomed the project but now remain frustrated since many promises and expectations have not been fulfilled. Although some local people are able to benefit from the project, the loss of natural resources that comes along with the land lease affects livelihoods of vulnerable groups – especially women and land users – considerably. However, this research doesn’t only disclose impacts on local people’s previous lives but also addresses strategies they adopt in the newly created situation that has opened up alternative spaces for renegotiations of power and legitimatisation. Therewith, this explorative study reveals new aspects of LSLA that have not been considered adequately by the investing company nor by the general academic discourse on LSLA.

Alpine Common Property Institutions under Change: Conditions for Successful and Unsuccessful Collective Action by Alpine Farmers in the Canton of Grisons, Switzerland

The protection and sustainable management of alpine summer pastures has been stated as a goal in Swiss national law since 1996, and direct payments from the state for summer pasturing have been tied to sustainability criteria since 2000. This reflects the increasing value of the alpine cultural landscape as a public good. However, provision of this public good remains in the hands of local farmers and their local common pool resource (CPR) institutions for managing alpine pastures. These institutions are increasingly struggling to maintain their institutional arrangements, particularly regarding the work needed to maintain the pastures. This paper examines two cases of local CPR institutions for managing alpine pastures in the Swiss Canton of Grisons that manifest different institutional developments in light of changing conditions. The differences in how these institutions reacted to change and the impacts this has had on the provision of the CPR are explained by focusing on relative prices, bargaining power, and ideology as drivers of institutional change that are often neglected within common property research. Key words: summer pasture management, institutional change, bargaining power, ideology

Molecular and pathogenetic aspects of tumor budding in colorectal cancer.

In recent years, tumor budding in colorectal cancer has gained much attention as an indicator of lymph node metastasis, distant metastatic disease, local recurrence, worse overall and disease-free survival, and as an independent prognostic factor. Tumor buds, defined as the presence of single tumor cells or small clusters of up to five tumor cells at the peritumoral invasive front (peritumoral buds) or within the main tumor body (intratumoral buds), are thought to represent the morphological correlate of cancer cells having undergone epithelial-mesenchymal transition (EMT), an important mechanism for the progression of epithelial cancers. In contrast to their undisputed prognostic power and potential to influence clinical management, our current understanding of the biological background of tumor buds is less established. Most studies examining tumor buds have attempted to recapitulate findings of mechanistic EMT studies using immunohistochemical markers. The aim of this review is to provide a comprehensive summary of studies examining protein expression profiles of tumor buds and to illustrate the molecular pathways and crosstalk involved in their formation and maintenance.

The Face of Power

Objective: In humans and other animals, open, expansive postures (compared to contracted postures) are evolutionary developed expressions of power and have been shown to cause neuroendocrine and behavioral changes (Carney, Cuddy, & Yap, 2010). In the present study we aimed to investigate whether power postures have a bearing on the participant’s facial appearance and whether others are able to distinguish faces after “high power posing” from faces after “low power posing”. Methods: 16 models were photographed 4-5 minutes after having adopted high and low power postures. Two different high power and two different low power postures were held for 2 minutes each. Power-posing sessions were performed on two consecutive days. High and low power photographs of each model were paired and an independent sample of 100 participants were asked to pick the more dominant and the more likeable face of each pair. Results: Photographs that were taken after adopting high power postures were chosen significantly more often as being more dominant looking. There was no preference when asked to choose the more likeable photograph (chance level). A further independent sample rated each photograph for head tilt, making it unlikely that dominance ratings were caused merely by the posture of the head. Consistently, facial width-to-height ratio did not differ between faces after high and low power posing. Conclusions: Postures associated with high power affect facial appearance, leading to a more dominant looking face. This finding may have implications for everyday life, for instance when a dominant appearance is needed.

Modern diatom, cladocera, chironomid, and chrysophyte cyst assemblages as quantitative indicators for the reconstruction of past environmental conditions in the Alps. II. Nutrients

Surface sediments from 68 small lakes in the Alps and 9 well-dated sediment core samples that cover a gradient of total phosphorus (TP) concentrations of 6 to 520 μg TP l-1 were studied for diatom, chrysophyte cyst, cladocera, and chironomid assemblages. Inference models for mean circulation log10 TP were developed for diatoms, chironomids, and benthic cladocera using weighted-averaging partial least squares. After screening for outliers, the final transfer functions have coefficients of determination (r2, as assessed by cross-validation, of 0.79 (diatoms), 0.68 (chironomids), and 0.49 (benthic cladocera). Planktonic cladocera and chrysophytes show very weak relationships to TP and no TP inference models were developed for these biota. Diatoms showed the best relationship with TP, whereas the other biota all have large secondary gradients, suggesting that variables other than TP have a strong influence on their composition and abundance. Comparison with other diatom – TP inference models shows that our model has high predictive power and a low root mean squared error of prediction, as assessed by cross-validation.

Outcome-based adaptive randomization for binary data in clinical trials---Compare and contrast

Monte Carlo simulation has been conducted to investigate parameter estimation and hypothesis testing in some well known adaptive randomization procedures. The four urn models studied are Randomized Play-the-Winner (RPW), Randomized Pôlya Urn (RPU), Birth and Death Urn with Immigration (BDUI), and Drop-the-Loses Urn (DL). Two sequential estimation methods, the sequential maximum likelihood estimation (SMLE) and the doubly adaptive biased coin design (DABC), are simulated at three optimal allocation targets that minimize the expected number of failures under the assumption of constant variance of simple difference (RSIHR), relative risk (ORR), and odds ratio (OOR) respectively. Log likelihood ratio test and three Wald-type tests (simple difference, log of relative risk, log of odds ratio) are compared in different adaptive procedures. ^ Simulation results indicates that although RPW is slightly better in assigning more patients to the superior treatment, the DL method is considerably less variable and the test statistics have better normality. When compared with SMLE, DABC has slightly higher overall response rate with lower variance, but has larger bias and variance in parameter estimation. Additionally, the test statistics in SMLE have better normality and lower type I error rate, and the power of hypothesis testing is more comparable with the equal randomization. Usually, RSIHR has the highest power among the 3 optimal allocation ratios. However, the ORR allocation has better power and lower type I error rate when the log of relative risk is the test statistics. The number of expected failures in ORR is smaller than RSIHR. It is also shown that the simple difference of response rates has the worst normality among all 4 test statistics. The power of hypothesis test is always inflated when simple difference is used. On the other hand, the normality of the log likelihood ratio test statistics is robust against the change of adaptive randomization procedures. ^

Perceived gender relations and sexual relations among undergraduate female students in the Mekong Delta of Vietnam

Background. Literature worldwide has documented associations between gender-based relationship inequity, sexual communication self-efficacy, and actual use of condoms and contraceptives among young women. However studies that have rigorously tested these associations in southern Vietnam are extremely rare. This study aimed to examine these associations and other current sexual practices among undergraduate female students in the Mekong Delta. Method. A qualitative study was conducted to examine the operationalization of the Theory of Gender and Power and to obtain salient and culture-relevant dimensions of perceived gender relations in the Mekong Delta of Vietnam. Sixty-four undergraduate female students from two universities participated in eight group discussions focusing on their viewpoints regarding national and local gender equity issues. A subsequent cross-sectional survey consisting of 1181 third-year female students from Can Tho University and An Giang University was conducted. Latent variable modeling and logistic regression were employed to examine the hypothesized associations. Results. Dimensions of perceived gender relations were attributable to theoretical structures of labor, power, and cathexis. Perceptions about gender inequities were comparable to findings from several reports, in which women were still viewed as inferior and subordinate to men. Among students who had ever had a boyfriend(s) (72.4%), 44.8% indicated that their boyfriend had ever asked for sex, 13% had ever had penile-vaginal sex, and 10.3% had ever had oral sex. For those who had ever had penile-vaginal sex, 33% did not use any contraceptive method at first sex. The greater a student’s perception that women were subordinate to men, the lower her self-efficacy for sexual communication and the lower her actual frequencies of asking for contraceptive or condom use. Sexual communication self-efficacy was marginally associated with actual contraceptive use (p=.039) and condom use (p=.092) at first sex. Conclusion. Sexual health promotion strategies should address the influence of perceived unequal gender relations on young women’s sexual communication self-efficacy and the subsequent impact on actual contraceptive and condom use.^

Optimal, minimax, and Bayesian two-stage designs in two-dose phase II clinical trials

Background: For most cytotoxic and biologic anti-cancer agents, the response rate of the drug is commonly assumed to be non-decreasing with an increasing dose. However, an increasing dose does not always result in an appreciable increase in the response rate. This may especially be true at high doses for a biologic agent. Therefore, in a phase II trial the investigators may be interested in testing the anti-tumor activity of a drug at more than one (often two) doses, instead of only at the maximum tolerated dose (MTD). This way, when the lower dose appears equally effective, this dose can be recommended for further confirmatory testing in a phase III trial under potential long-term toxicity and cost considerations. A common approach to designing such a phase II trial has been to use an independent (e.g., Simon's two-stage) design at each dose ignoring the prior knowledge about the ordering of the response probabilities at the different doses. However, failure to account for this ordering constraint in estimating the response probabilities may result in an inefficient design. In this dissertation, we developed extensions of Simon's optimal and minimax two-stage designs, including both frequentist and Bayesian methods, for two doses that assume ordered response rates between doses. ^ Methods: Optimal and minimax two-stage designs are proposed for phase II clinical trials in settings where the true response rates at two dose levels are ordered. We borrow strength between doses using isotonic regression and control the joint and/or marginal error probabilities. Bayesian two-stage designs are also proposed under a stochastic ordering constraint. ^ Results: Compared to Simon's designs, when controlling the power and type I error at the same levels, the proposed frequentist and Bayesian designs reduce the maximum and expected sample sizes. Most of the proposed designs also increase the probability of early termination when the true response rates are poor. ^ Conclusion: Proposed frequentist and Bayesian designs are superior to Simon's designs in terms of operating characteristics (expected sample size and probability of early termination, when the response rates are poor) Thus, the proposed designs lead to more cost-efficient and ethical trials, and may consequently improve and expedite the drug discovery process. The proposed designs may be extended to designs of multiple group trials and drug combination trials.^

Espacio, comunicación y convivencia : problemas éticos de la ciudad latinoamericana

El artículo enfoca los problemas de convivencia en las ciudades latinoamericanas, marcadas por procesos de urbanización sin articulación, regidos por lógicas de poder y caracterizados por la falta de equilibrio y equidad. Se exploran las posibilidades de pasar de territorios de supervivencia, con relaciones sociales de dominio y violencia, a espacios de comunicación y a lugares de sentido, a través de prácticas, políticas y estrategias de convivencia.
