It is expected that the number of elected female mayors in local government will increase globally, yet no major progress has been registered lately despite the increased focus on the topic. At the European level, no country exceeds 40% female mayors or other leaders of the municipal council (or equivalent), with the highest descriptive representation of 39.1% in Iceland. Following the 2020 elections in Romania, only around 5% of mayors were female with a strong over-representation of male mayors. The current study aims to analyze the male–female distribution of mayors, the degree of re-election, the relationship between the number of candidates and re-election of incumbents, and how these factors impact female political representation at the local level in Romania. Thus, we argue that a high degree of re-election of incumbents may be a barrier to women’s access to the position of mayor. In addition, it is important to determine whether female incumbents are as successful as their male counterparts in being re-elected. While there is an extensive body of literature on incumbency that covers a range of topics, there is a gap in the literature regarding the proposed subject. The present research aims to fill the gap and contribute to a better understanding of the political representation of women in Eastern Europe. We utilized a dataset of Romanian elections from 2008 to 2020 to test our hypotheses. Our findings indicate that during the studied period, more than 95% of mayors were male, the re-election was a frequent occurrence in Romania with a percentage ranging from 70.82% (2008–2012) to 72% (2012–2016 and 2016–2020), and female incumbents were just as likely to be re-elected as their male counterparts.

Bladder cancer, a common malignancy of the urinary system, is routinely treated with radiation, chemotherapy, and surgical excision. However, these strategies have inherent limitations and may also result in various side effects. Immunotherapy has garnered considerable attention in recent years as a novel therapeutic approach. It harnesses and activates the patient’s immune system to recognize and eliminate cancer cells, which not only prolongs therapeutic efficacy but also minimizes the toxic side effects. Several immune checkpoint inhibitors and cancer vaccines have been developed for the treatment of bladder cancer. Whereas blocking immune checkpoints on the surface of tumor cells augments the effect of immune cells, immunization with tumor-specific antigens can elicit the production of anti-tumor immune effector cells. However, there are several challenges in applying immunotherapy against bladder cancer. For instance, the efficacy of immunotherapy varies considerably across individual patients, and only a small percentage of cancer patients are responsive. Therefore, it is crucial to identify biomarkers that can predict the efficacy of immunotherapy. Pelvic lymph nodes are routinely dissected from bladder cancer patients during surgical intervention in order to remove any metastatic tumor cells. However, some studies indicate that pelvic lymph node dissection may reduce the efficacy of immunotherapy by damaging the immune cells. Therefore, the decision to undertake pelvic lymph node removal should be incumbent on the clinical characteristics of individual patients. Thus, although immunotherapy has the advantages of lower toxic side effects and long-lasting efficacy, its application in bladder cancer still faces challenges, such as the lack of predictive biomarkers and the effects of pelvic lymph node dissection. Further research is needed to explore these issues in order to improve the efficacy of immunotherapy for bladder cancer. Full article

The ideas of the sharing economy have facilitated innovative business applications, such as Uber and Airbnb. As an example of a sharing economy application, ridesharing services take advantage of underutilized resources to create economic value. However, the unruly design of ridesharing systems may make urban traffic more congested and cause other technology-organization-environment issues. This study explores the application of blockchain and smart contract technologies to enhance ridesharing services by harvesting the blockchain benefits of transaction traceability, process transparency, system automation and disintermediation. After presenting system design and implementation details for building and deploying a blockchain-based system to support the reengineered ridesharing service with required business functions, we conduct functionality/performance tests and theory-based comparative analysis to confirm its feasibility and applicability. The results reveal that our system with blockchain-enabled benefits is superior to incumbent ridesharing systems. Moreover, while prior research rarely reports the design and implementation details of blockchain-based systems to support sharing economy services, this paper primarily contributes to extant literature by not only proposing a layered system architecture adapting blockchain and smart contracts into the desired ridesharing service but also demonstrating the design and implementation details, covering the development tools, the deployment environment and the deployed smart contracts.

In recent years, online retail has developed rapidly. However, as consumer demands become increasingly sophisticated, the traditional online retail model has encountered difficulties with respect to meeting consumers’ needs. As a result, numerous retailers with offline physical stores have emerged in the online retail industry. This paper constructs a game model for the invasion of the market by e-commerce retailers with offline physical stores in a context in which a traditional, online-only incumbent retailer is already in the market. Compared with the new entrant, the incumbent has the advantage of an established good reputation, and consumers prefer the products of the incumbent. This research shows that as consumers’ product valuations increase, the following three situations may occur: a partially covered market, a multiple-equilibrium market or a fully covered market. In a partially covered market, the incumbency advantage does not affect the entrant. In a multiple-equilibrium market or fully covered market, the incumbency advantage impacts the profits of the entrant. However, in a fully covered market, if the incumbency advantage is too large, the profits of both retailers are damaged. Finally, this paper finds that offline physical stores can provide positive benefits to entrants. When consumers are highly sensitive to services, opening offline physical stores is an effective intrusion strategy that entrants can use to overcome the incumbency advantage. Full article

Parties and their leaders are linked programmatically and non-programmatically with citizens, incentivising the latter to vote in elections and seeking to influence their choices. In this paper, we analyse the effects of politician–voter linkages on the electoral performance of incumbent mayors in Chile and on electoral turnout in their municipalities. To measure the linkages, we use personal meetings that mayors hold with citizens. While some mayors use this mechanism to solve problems of general interest (programmatic meetings), others do so to provide bureaucratic advantages or benefits for their constituents (non-programmatic meetings). We use a database of 44,162 personal meetings aggregated from Chile’s 345 municipalities. We argue that increases in the number of meetings positively impact electoral turnout and increase the chances of success for incumbent mayors when they compete for re-election. This effect is particularly significant in the case of electoral performance and the re-election of mayors in municipalities with high levels of rurality. Finally, we report that the meetings not only help mayors to link with their constituents but also help them to publicise their political work. Full article

Increasingly, in many industries, companies commercialize their technology and innovations through patenting to gain an edge over competition. Within the maritime sector, while literature on innovation is expanding, issues related to the importance of intangible assets, such as patenting, for the participant firms of the industry remain unaddressed. Utilizing innovational frameworks and patent data withdrawn from European Patent Organization’s (EPO’s) database, the aim of this paper is to investigate the innovative level, in terms of patents granted, of incumbent market actors in liner shipping. Apart from patent counts, this exercise sheds light on the areas to which these patents apply, providing a classification while also investigating additional attributes which relate to patent citations, investors and applicants. Although results indicate a varying degree of utilization of the patenting system amongst liner carriers, they nonetheless affirm to some extent that knowledge creation is a valuable tool in the arsenal of some liner carriers, and that patenting is one of the various means utilized to enhance their market position and achieve a sustained competitive advantage. In addition, findings suggest that liner carriers’ innovative efforts have, based on the forward citations received, some significance, while they focus primarily the development of patented technologies which enhance the operational efficiency of their vessels. In this respect, the investigation undertaken sheds some light and provides a novel perspective on understanding the behaviour and innovative propensity of liner shipping companies. Full article

Nowadays, distribution network operators are urged by regulatory authorities to reduce the load disruptions due to extreme weather events, i.e., to enhance network resilience: in particular, in Italy they are required to present a yearly plan (called “resilience plans”) describing the interventions aimed to improve network resilience. To this purpose, they need new methodologies and tools to assess the network resilience and to quantify the benefits of countermeasures. This paper proposes the application of a risk-based framework and tool to assess the impacts of extreme weather events in T&D grids, which anticipate critical network situations in presence of incumbent weather threats. To do this, the forecasting of weather events is combined with the component vulnerability models in order to predict which components are more prone to fail. Based on this set of components, the set of most risky contingencies is identified and their impacts on the distribution network in terms of unsupplied load are quantified. The major advantage of the applied methodology is its generality: in fact, it is applicable to both distribution and transmission systems as well as integrated transmission and distribution (T&D) systems, considering the peculiarities of each type of grid, in terms of operation, maintenance and component vulnerabilities. In particular, the application refers to a distribution network connected to a portion of high voltage transmission system in a mountainous zone, with focus on two major threats in the area, i.e., wet snow and fall of trees induced by combined wind and snow. The methodology also quantifies the benefits brought to the system resilience by countermeasures such as reconductoring, optimal reconfiguration or new right-of-way maintenance procedures. Simulations demonstrate the ability of the methodology to support T&D operators in an operational planning context in case of different incumbent threats. Full article

Entering a foreign market is challenging given the fierce competition posed by local incumbents. The literature suggests that when entering a foreign market, it is advantageous to locate where there are agglomeration benefits. Given the dynamic nature of regional development, foreign firms have multiple location options. While the literature has primarily focused on developed country multinationals’ (DMNEs) location decisions, emerging market multinationals (EMNEs) are increasingly becoming influential in high-tech industries. Due to differences in DMNE and EMNE resource endowments, they may consider alternative options when locating abroad and, thus, we examine these nuances. Using multinomial logistic regression, we investigate domestic and foreign location patterns of firms within the U.S. biopharmaceutical industry as of 2018. We constructed a unique dataset of 19,962 U.S. locations and examined the location patterns of DMNEs and EMNEs from 61 countries and territories. Given the heterogeneity of regional development in the U.S., we developed a typology that stratifies regions into four categories (developed, growth, transitioning, and nascent). Counterintuitively, we find that foreign multinationals are more likely to be attracted to less developed regions than domestic firms and have different location patterns, not only compared to domestic firms, but also with respect to each other.

Energy transitions are complex and involve interrelated changes in the socio-technical dimensions of society. One major barrier to renewable energy transitions is lock-in from the incumbent socio-technical regime. This study evaluates Energy Product–Service Systems (EPSS) as a renewable energy market mechanism. EPSS offer electricity service performance instead of energy products and appliances for household consumers. Through consumers buying the service, the provider company is enabled to choose, manage and control electrical appliances for best-matched service delivery. Given the heterogenous market players and future uncertainties, this study aims to identify the necessary conditions to achieve a sustainable renewable energy market. Simulation-Based Design for EPSS framework is implemented to assess various hypothetical market conditions’ impact on market efficiency in the short term and long term. The results reveal the specific market characteristics that have a higher chance of causing unexpected results. Ultimately, this paper demonstrates the advantage of implementing Simulation-Based Design for EPSS to design retail electricity markets for renewable energy under competing market mechanisms with heterogenous economic agents.

Entrepreneurship and more, particularly ecopreneurship, are essential to drive the sustainable transitions needed in food supply chains. Existing pedagogic frameworks should address these academic disciplines and they should be embedded in the educational curricula. Even when ideas are formed that can drive sustainable change, the process from ideation to commercialization can be difficult: the so-called “valley of death.” This aim of this conceptual paper is to consider pedagogic and program design and the mechanisms required to enaction of a body of practice around entrepreneurship and, more specifically, ecopreneurship, within academic curricula and associated business incubators. This makes this paper of particular interest for academia, policy makers and industry support sectors alike. An existing university that has both a student enterprise and ecopreneurship program and an established agri-technology business incubator and accelerator is used as a case study to provide insight into how progress from ideation to commercialization can be more readily supported in a university setting. From a pedagogical perspective, it is incumbent to develop new conceptual, methodological and theoretically underpinned spiral pedagogies to teach and support future generations of learners at agricultural and land-based colleges and universities as to how to exploit and take advantage of entrepreneurial and ecopreneurial business opportunities. Productization, too, needs to be embedded into the ecopreneurial pedagogy and also consideration of how businesses and their associated ecopreneurs navigate from ideation to successful product/service commercialization.

Push-Pull-Mooring framework is adopted to identify the antecedents affecting users’ switching intention from Internet payment to mobile payment. Using the data obtained from 264 valid respondents, the results show that both the mooring factors (perceived switching cost and personal innovativeness) and pull factors (relative advantages of substitute information technology and critical mass) are direct antecedents affecting customer switching behavior. In addition, mooring factors could moderate the relationship between push factors (dissatisfaction on system quality and dissatisfaction on service quality) as well as pull factors and customer switching intention. Managerial implications of findings were provided to payment service providers for maintaining incumbent customers and attracting potential customers. Full article

The InAs/InAsSb (Gallium-free) type-II strained-layer superlattice (T2SLS) has emerged in the last decade as a viable infrared detector material with a continuously adjustable band gap capable of accommodating detector cutoff wavelengths ranging from 4 to 15 µm and beyond. When coupled with the unipolar barrier infrared detector architecture, the InAs/InAsSb T2SLS mid-wavelength infrared (MWIR) focal plane array (FPA) has demonstrated a significantly higher operating temperature than InSb FPA, a major incumbent technology. In this brief review paper, we describe the emergence of the InAs/InAsSb T2SLS infrared photodetector technology, point out its advantages and disadvantages, and survey its recent development.

Pork-barrel spending is the use of federal money for localized projects that yield only a narrow geographic benefit. It is a commonly held belief that politicians use this spending to improve their chances of re-election. One way that an incumbent can increase their chances of re-election is through increased fundraising. Political entrepreneurs see this opportunity and attempt to benefit from these projects in exchange for campaign contributions. This paper investigates whether incumbents are able to use their position to bolster their campaign contributions. I find pork-barrel spending and political contributions to be positively related, but this effect is only present when the incumbent properly times the project. I also find that general federal appropriations do not have the same impact. This supports the claim that pork-barrel spending can be used as a currency in the marketplace for political capital.

The proliferation of Internet-of-Things (IoT) technology and its reliance on the license-free Industrial, Scientific, and Medical (ISM) bands have rendered radio spectrum scarce. The IoT can nevertheless obtain great advantage from Cognitive Radio (CR) technology for efficient use of a spectrum, to be implemented in IEEE 802.11af-based primary networks. However, such networks require a geolocation database and a centralized architecture to communicate white space information on channels. On the other hand, in spectrum sensing, CR presents various challenges such as the Hidden Primary Terminal (HPT) problem. To this end, we focus on the most recently released standard, i.e., IEEE 802.11ah, in which IoT stations can first be classified into multiple groups to reduce collisions and then they can periodically access the channel. Therein, both services are similarly supported by a centralized server that requires signaling overhead to control the groups of stations. In addition, more regroupings are required over time due to the frequent variations in the number of participating stations, which leads to more overhead. In this paper, we propose a new Multiple Access Control (MAC) protocol for CR-based IEEE 802.11ah systems, called Restricted Access with Collision and Interference Resolution (RACIR). We introduce a decentralized group split algorithm that distributes the participating stations into multiple groups based on a probabilistic estimation in order to resolve collisions. Furthermore, we propose a decentralized channel access procedure that avoids the HPT problem and resolves interference with the incumbent receiver. We analyze the performance of our proposed MAC protocol in terms of normalized throughput, packet delay and energy consumption with the Markov model and analytic expressions. The results are quite promising, which makes the RACIR protocol a strong candidate for the CR-based IoT environment. Full article

Over the past century, nearly two hundred times a governor has appointed an individual to fill a vacant Senate seat. This research seeks to understand the electoral fates of these appointed senators. First, I address the question of when and under what conditions an appointed senator will choose to run for reelection to the seat. Then, should they choose to run for that office in the next election, they are in the rare position of being an incumbent who has not previously won an election to that particular office. Although these appointed senators are not on equal footing as other first-term senators, they still provide a unique circumstance worthy of further examination. I find that those appointed senators who had previously held an elected office were more likely to run to maintain the Senate seat. I also find that appointed senators fare slightly worse than other first-term senators did when campaigning for reelection. Full article
