Long-term collaborations are crucial in many creative domains. Although there is ample research on why people collaborate, our knowledge about what drives some collaborations to persist and others to decay is still emerging. In this paper, we extend theory on third-party effects and collaborative persistence to study this question. We specifically consider the role that a third party’s helpful behavior plays in shaping tie durability. We propose that when third parties facilitate helpfulness among their group, the collaboration is stronger, and it persists even in the third’s absence. In contrast, collaborations with third parties that are nonhelpful are unstable and dissolve in their absence. We use a unique data set comprising scientific collaborations among pairs of research immunologists who lost a third coauthor to unexpected death. Using this quasi-random loss as a source of exogenous variation, we separately identify the effect of third parties’ traditional role as an active agent of collaborative stability and the enduring effect of their helpful behavior—as measured by acknowledgments—on the persistence of the remaining authors’ collaboration. We find support for our hypotheses and find evidence that one mechanism driving our effect is that helpful thirds make their coauthors more helpful.

AbstractThird parties have been active in assisting adversarial states to navigate their international river disputes. By using the carrot and stick to facilitate compromise, mediators have also participated in the negotiations leading to the signing of treaties over international rivers. Yet, due to the nature of the issue confronting riparian states, the long-term impact of these efforts is likely to be unstable cooperation rather than cooperation. This is still an important contribution, because the absence of mediation efforts may contribute to an environment of conflict. However, since riparian states confront a relationship that involves the need to continuously manage disputes that arise as states develop their international rivers, a mediator may be more effective in facilitating cooperation if it assists developing states with a history of animosity to establish effectively designed river basin commissions and it oversees the implementation of treaties. Participating in the initial years of a treaty's implementation by coordinating the donor community to underwrite projects can minimize the potential disputes riparians confront. An effectively designed river basin commission can assist in facilitating cooperation long after the mediator has departed from the region. To demonstrate this argument, the article draws on the Indus River case, which has lived through four different phases. The Euphrates and Tigris Rivers are used to illustrate the argument's ability to explain other cases.

Long-term effects in a neurosurgically separated twin pair were illuminated by standard psychological test scores obtained over a period from 2 to 38 years of age. Interdigitation of the gyri of their right frontal lobes had necessitated separation in two stages at 4 months of age. One twin clearly suffered some brain injury and showed some impairment during the testing at 5 years of age. The scores of both twins rose at the adult testing. The brighter twin has an IQ comparable to that of the mother. The unique data set is a kind of model for long-term assessment of early brain surgery, particularly with craniopagus twins.

After surveying the literature on the causes, consequences, and management of civil wars, we argue that novel ways of examining civil war management are needed. We advocate for a developmental view of civil wars in order to better understand how to prevent the escalation of low-level armed conflict to full-scale civil war. To prevent full-scale civil war, third parties need to (a) respond swiftly, (b) have the will and ability to impose tangible costs on (and offer benefits to) governments and rebels, and (c) remain involved over the long term. Our analysis shows that typical third-party civil war management approaches (mediation, peacekeeping, and intervention) fail to adequately address at least one of these issues. This motivates our argument in favor of focusing on a different type of third party that could arguably play a particularly constructive role in civil war prevention: highly structured intergovernmental organizations.

Abstract. As part of ESA's climate change initiative high vertical resolution ozone profiles from three instruments all aboard ESA's Envisat (GOMOS, MIPAS, SCIAMACHY) in combination with ESA's third party missions (OSIRIS, SMR, ACE-FTS) are to be combined in order to create an essential climate variable data record for the last decade. A prerequisite before combining data is the examination of differences and drifts between the datasets. In this paper, we present a detailed analysis of ozone profile differences based on pairwise collocated measuerements, including the evolution of the differences with time. Such a diagnosis is helpful to identify strengths and weaknesses of each data set that may vary in time and introduce uncertainties in long-term trend estimates. Main results of this paper indicate that the 6 instruments perform well in the stratosphere particularly between 20 and 40 km with a mean relative difference of ±5% (middle latitudes) to ±10% (tropics). Larger differences and variability in the differences are found in the upper troposphere lower stratosphere region and in the mesosphere. The analysis reveals that the relative drift between the sensors is not statistically significant for most pairs of instruments.

While the long-term effects of COVID-19 are yet to be determined, its immediate impact on crowdfunding is nonetheless significant. This study takes a computational approach to more deeply comprehend this change. Using a unique data set of all the campaigns published over the past two years on GoFundMe, we explore the factors that have led to the successful funding of a crowdfunding project. In particular, we study a corpus of crowdfunded projects, analyzing cover images and other variables commonly present on crowdfunding sites. Furthermore, we construct a classifier and a regression model to assess the significance of features based on XGBoost. In addition, we employ counterfactual analysis to investigate the causality between features and the success of crowdfunding. More importantly, sentiment analysis and the paired sample t-test are performed to examine the differences in crowdfunding campaigns before and after the COVID-19 outbreak that started in March 2020. First, we note that there is significant racial disparity in crowdfunding success. Second, we find that sad emotion expressed through the campaign's description became significant after the COVID-19 outbreak. Considering all these factors, our findings shed light on the impact of COVID-19 on crowdfunding campaigns.

This paper covers the question if and how incentive schemes work evaluated by their impact on company performance (market capitalization and profit before tax). Based on a unique data set for German executive directors of DAX companies it can be proved that neither short (STI) nor long term incentives (LTI) plans necessarily support the company success. It rather depends on the efficiency of each plan, i. e. on its design. Special attention has to be paid on target setting. Short term focused objectives often miss their targets, whereas long term oriented objectives significantly support the company success. To solve the prisoner’s dilemma between employers and employees by a quasi-endless game, additional measures may be helpful, such as share ownership guidelines.

Disputes filed at the World Trade Organization (WTO) are attracting a growing number of third parties. Most observers argue that their participation influences the institution's rulings. The authors argue that third parties undermine pretrial negotiations; their influence on rulings is conditioned by this selection effect. They test their hypotheses, along with the conventional wisdom, using a data set of WTO disputes initiated through 2002. Consistent with the authors' argument, they find that third-party participationlowersthe prospects for early settlement. Controlling for this selection effect, the evidence also suggests that third-party support increases the chances of a legal victory at the WTO.

Few studies explain how wars affect trade with third parties. We argue that wartime trade policies should raise trade with friendly and enemy-hostile third parties but reduce trade with hostile and enemy-friendly third parties. At the same time, the private motivation of firms and households may be incompatible with national wartime trade policies and constrain the effectiveness of wartime trade policies. Our directed dyadic data set consists of almost all of the states from 1885 to 2000. Running a high definition fixed effects regression with two-way clustering of standard errors, we find that hostile third parties tended to reduce trade with a combatant state by roughly 30 percent. In addition, trade with third parties friendly to the enemy fell by a similar magnitude. In contrast, on average, war hardly affected trade with third parties because of substitution of war-ridden markets with third-party business partners.

BackgroundTransnational tobacco companies (TTCs) have heavily publicised their argument that standardised tobacco packaging will increase the illicit tobacco trade. Leaked Philip Morris International (PMI) documents suggest that the company may have intended to use third parties to promulgate this argument in the UK.MethodsWe examined articles in UK newspapers (1 April 2013 to 31 March 2015) from LexisNexis for presence and nature of tobacco industry data. We also examined documents released by Freedom of Information requests made to Scottish Councils for evidence of how PMI operationalised its third-party strategy.FindingsTwo-thirds of newspaper articles (63%, 99/157) mentioned a PMI consultant; 36% of which did not disclose this industry funding. Most articles mentioned counterfeit tobacco, illicit whites or both (72%, 113/157), while few (4%, 7/157) specifically mentioned tobacco industry illicit tobacco and none explained that the latter can include tobacco-company involvement. Freedom of Information documents revealed that the PMI consultant sought to build relationships with Trading Standards officers, conducted undercover test purchases (UTPs) in illicit tobacco ‘hotspots’ and may have promoted unrepresentative findings in the media. While the data set featured PMI data predominantly, other TTCs also engaged in third-party techniques to promulgate messages on illicit tobacco.InterpretationPMI engaged a third party, seemingly with the aim of securing media coverage on illicit tobacco positing that standardised packaging would worsen the problem. The predominant focus of articles which featured industry-funded data and information was on counterfeit tobacco despite official data showing tobacco-industry illicit tobacco as the most prevalent. Other jurisdictions considering the policy should anticipate that third parties will promote the illicit-trade argument.

Sharing data among organizations plays an important role in security and data mining. In this paper, the authors describe a Data Sharing Miner and Analyzer (DASMA) system that simulates data sharing among N organizations. Each organization has its own enforced policy. The N organizations share their data based on trusted third party. The system collects the released data from each organization, processes it, mines it, and analyzes the results. Sharing in DASMA is based on trusted third parties. However, organizations may encode some attributes, for example. Each organization has its own policy represented in XML format. This policy states what attributes can be released, encoded, and randomized. DASMA processes the data set and collects the data, combines it, and prepares it for mining. After mining, a statistical report is produced stating the similarities between mining with data sharing and mining without sharing. The authors test, apply data sharing, enforce policy, and analyze the results of two separate datasets in different domains. The results indicate a fluctuation on the amount of information loss using different releasing factors.
