By now it is widely recognized that the more serious threats of climate change are associated with abrupt events capable of inflicting losses on a catastrophic scale. Consequently, the main role of climate policies is to balance between mitigation efforts, aimed at delaying (or even preventing) the occurrence of such events, and adaptation actions, aimed at minimizing the damage inflicted upon occurrence. The former affects the accumulation of greenhouse gases in the atmosphere; the latter determines the impact of loss once the event occurs. This work examines the tradeoffs associated with these two types of policy measures by characterizing the optimal mitigation–adaptation mix in the long run.

Public administration research has thus far focused on the responses of bureaucracies to top-down pressures by elected politicians. By comparison, bureaucracies' responses to bottom-up public pressures, such as media coverage and social protest, and the micro-mechanisms that underlie the variation in their response, have received less attention. This study contributes to current literature by analysing the extent to which subjection to political control shapes the direct response of bureaucracies to bottom-up public pressures. Based on current literature, we explore two distinct micro-mechanisms: on the one hand, building, inter alia, on principal–agent theory, we would expect higher levels of political control to render bureaucracies more attentive to public pressures in order to preempt intervention by politicians who are reliant on public support (the principal–agent mechanism). Conversely, building on regulation theory, we would expect autonomous agencies to exhibit their attentiveness to salient public pressures in order to compensate for their precarious democratic legitimacy (the legitimacy-deficit mechanism). Empirically, we analyse the responses of a diverse set of 36 bureaucracies to the unprecedented social protests that took place in Israel during 2011. We focus on bureaucracies', including independent agencies', symbolic responses via advertising campaigns. Our analysis shows that higher levels of political control enhanced the inclination of bureaucracies to engage in symbolic interactions in response to the social protests, supporting our extended version of the principal–agent model.

Adolescents may engage in risk behaviors to cope with the negative psychological impacts resulting from exposure to political violence. Guided by the Deterioration Deterrence Model and General Strain Theory, the present study assessed the mediating role of school support and posttraumatic stress (PTS) on two adolescent risk behaviors (i.e., school violence and drug use) among Arab and Jewish Israeli adolescents. We analyzed data from a nationally representative survey that consisted of 4,733 Israeli high school students (54.5% females; 63.2% Jewish) following the Second Lebanon War. Structural equation modeling using weighted data bootstrapped with 2,000 iterations evaluated the mediated effects of school support and PTS. The results showed that both school support and PTS mediated the pathways from political violence exposure to school violence and drug use. However, although school support and PTS fully mediated the relationship between political violence exposure and these risk behaviors for Jewish students, school support and PTS only partially mediated the relationships for Arab students. While school support can help decrease the detrimental effect of exposure to terrorism and war, Israeli adolescents exposed to more political violence may perceive receiving less school support than those experiencing less exposure. Findings of this study provide evidence for the theorized mediated pathways between political violence exposure and adolescent risk behaviors by PTS and school support. The study serves as a basis for future research that can unpack the relationship between exposure to political violence and adolescent risk-taking behaviors.

Polyesters derived from the $\alpha$-hydroxy acids, lactic acid, and glycolic acid, are the most common biodegradable polymers in clinical use. These polymers have been tailored for a range of applications that require a physical material possessing. The physical and mechanical properties of these polymers fit the specific application and also safely biodegrade. These polymers are hydrophobic and do not possess functional side groups. This does not allow hydrophilic or hydrophobic manipulation, conjugation of active agents along the polymer chain, etc. These manipulations have partly been achieved by block copolymerization with, for example, poly(ethylene glycol), to obtain an amphiphilic copolymer. The objective of this review is to survey PLA functional copolymers in which functional $\alpha$-hydroxy acids derived from amino acids are introduced along the polymer chain, allowing endless manipulation of PLA. Biodegradable functional polyesters are one of the most versatile biomaterials available to biomedical scientists. Amino acids with their variable side chains are ideal candidates for synthesizing such structural as well as stereochemically diverse polymers. They render control over functionalization, conjugation, crosslinking, stimulus responsiveness, and tunable mechanical/thermal properties. Functionalized amino acid derived polyesters are widely used, mainly due to advancement in ring opening polymerization (primarily O-carboxyanhydride mediated). The reaction proceeds under milder conditions and yields high molecular weight polymers. We reviewed on advances in the synthetic methodologies for poly-$\alpha$-hydroxy esters derived from amino acids with appropriate recent examples.

Polylactide (PLA) and its copolymers are hydrophobic polyesters used for biomedical applications. Hydrogel medicinal implants have been used as drug delivery vehicles and scaffolds for tissue engineering, tissue augmentation and more. Since lactides are non-functional, they are copolymerized with hydrophilic monomers or conjugated to a hydrophilic moiety to form hydrogels. Copolymers of lactic and glycolic acids with poly(ethylene glycol) (PEG) provide thermo-responsive hydrogels. Physical crosslinking mechanisms of PEG-PLA or PLA-polysaccharides include: lactic acid segment hydrophobic interactions, stereocomplexation of D and L-lactic acid segments, ionic interactions, and chemical bond formation by radical or photo crosslinking. These hydrogels may also be tailored as stimulus responsive (pH, photo, or redox). PLA and its copolymers have also been polymerized to include urethane bonds to fabricate shape memory hydrogels. This review focuses on the synthesis, characterization, and applications of PLA containing hydrogels.

Marketing tools that enable pre-purchase experience (e.g., product trials, sampling) are considered efficient means of reducing uncertainty and increasing demand for unfamiliar products. It is widely agreed that having more information improves the quality of choice, so demonstrations, sampling, and other experience-generating marketing tools are expected to increase consumers' welfare. The current paper challenges this concept by suggesting that experiencing some product types for a limited time might provide unrepresentative information, and thus might result in suboptimal choices. In three experiments, we evaluated the effect of potentially unrepresentative experience on consumer product acceptance. The results show that while experiencing products affects consumers even when it provides little information, the effect might be positive or negative, depending on the product value distribution. Specifically, short experience with the product increases the appeal of negatively skewed products, which appear appealing after a short, yet unrepresentative experience. Yet short experience impairs the appeal of positively skewed products, which appear unappealing given short or low-intensity experience. This pattern emerges even though the most likely result of a given sample is not a good predictor of the expected utility of the product. Theoretical and practical implications are discussed.

This paper examines populist claims-making in US presidential elections. We define populism as a discursive strategy that juxtaposes the virtuous populace with a corrupt elite and views the former as the sole legitimate source of political power. In contrast to past research, we argue that populism is best operationalized as an attribute of political claims rather than a stable ideological property of political actors. This analytical strategy allows us to systematically measure how the use of populism is affected by a variety of contextual factors. Our empirical case consists of 2,406 speeches given by American presidential candidates between 1952 and 1996, which we code using automated text analysis. Populism is shown to be a common feature of presidential politics among both Democrats and Republicans, but its prevalence varies with candidates' relative positions in the political field. In particular, we demonstrate that the probability of a candidate's reliance on populist claims is directly proportional to his distance from the center of power (in this case, the presidency). This suggests that populism is primarily a strategic tool of political challengers, and particularly those who have legitimate claims to outsider status. By examining temporal changes in populist claims-making on the political left and right, its variation across geographic regions and field positions, and the changing content of populist frames, our paper contributes to the debate on populism in modern democracies, while integrating field theory with the study of institutional politics.

Circadian rhythms in behaviour and physiology are important for animal health and survival. Studies with individually isolated animals in the laboratory have consistently emphasized the dominant role of light for the entrainment of circadian rhythms to relevant environmental cycles. Although in nature interactions with conspecifics are functionally significant, social signals are typically not considered important time-givers for the animal circadian clock. Our results challenge this view. By studying honeybees in an ecologically relevant context and using a massive data set, we demonstrate that social entrainment can be potent, may act without direct contact with other individuals and does not rely on gating the exposure to light. We show for the first time that social time cues stably entrain the clock, even in animals experiencing conflicting photic and social environmental cycles. These findings add to the growing appreciation for the importance of studying circadian rhythms in ecologically relevant contexts.
