Clustering and hotel room prices in Dubai

In this article, we study the influence of the room properties, hotel amenities, hotel location, and, more importantly, the characteristics of hotels in the surrounding area on the prices of hotel rooms. The effects of different determinants are estimated using the hedonic price model for a cross-section of 250 hotels in Dubai. In addition to the typical characteristics of hotels and hotel rooms such as hotel amenities, star rating, and room size, we include location-specific characteristics such as accessibility to public transportation, airport, and, more importantly, clustering variables to capture the effects of local competition and spillovers from surrounding hotels. Our results indicate significant and strong effects of accessibility to attractions, transportation, hotel’s star rating, and room size, as expected. Our estimations also indicate that local competition reduces the room price, and local quality spillover increases the room price, and both effects are predominantly limited to the hotel’s immediate surroundings. Our estimations indicate that having one more hotel in the immediate surroundings decreases the room price by about one percent, and an increase in the average quality of the hotels in the immediate surroundings by one star rating increases the room price by more than 20%.

Slow expanders invade by forming dented fronts in microbial colonies

Most organisms grow in space, whether they are viruses spreading within a host tissue or invasive species colonizing a new continent. Evolution typically selects for higher expansion rates during spatial growth, but it has been suggested that slower expanders can take over under certain conditions. Here, we report an experimental observation of such population dynamics. We demonstrate that mutants that grow slower in isolation nevertheless win in competition, not only when the two types are intermixed, but also when they are spatially segregated into sectors. The latter was thought to be impossible because previous studies focused exclusively on the global competitions mediated by expansion velocities, but overlooked the local competitions at sector boundaries. Local competition, however, can enhance the velocity of either type at the sector boundary and thus alter expansion dynamics. We developed a theory that accounts for both local and global competitions and describes all possible sector shapes. In particular, the theory predicted that a slower on its own, but more competitive, mutant forms a dented V-shaped sector as it takes over the expansion front. Such sectors were indeed observed experimentally, and their shapes matched quantitatively with the theory. In simulations, we further explored several mechanisms that could provide slow expanders with a local competitive advantage and showed that they are all well-described by our theory. Taken together, our results shed light on previously unexplored outcomes of spatial competition and establish a universal framework to understand evolutionary and ecological dynamics in expanding populations.

Determinants of Staff Localization in Headquarters-Subsidiary-Subsidiary Relationships

This paper investigates how cultural distance, the local experience of a foreign subsidiary, and the intensity of local competition jointly affect the staff localization of MNEs’ subsidiaries. While previous studies on the effects of cultural distance have mainly focused on the gap between home and host countries, we extend the existing “home-host” country perspective to the home-intermediary-host country relationship. This study regards Korea as an intermediary country and utilizes 520 observations from a unique survey conducted by the Export-Import Bank of Korea from 2006 to 2013. The results suggest that the impact of cultural distance on staff localization is a function of local experience and competitive environment in the home-intermediate-host relationship structure. This paper makes a theoretical contribution to our understanding of the behavior of multinational corporations by expanding the cultural distance perspective between the home and host countries explored in previous research to the home-subsidiary-subsidiary structure.

Sex-biased demography modulates male harm across the genome

Recent years have seen an explosion of theoretical and empirical interest in the role that kin selection plays in shaping patterns of sexual conflict, with a particular focus on male harming traits. However, this work has focused solely on autosomal genes, and as such it remains unclear how demography modulates the evolution of male harm loci occurring in other portions of the genome, such as sex chromosomes and cytoplasmic elements. To investigate this, we extend existing models of sexual conflict for application to these different modes of inheritance. We first analyse the general case, revealing how sex-specific relatedness, reproductive value and the intensity of local competition combine to determine the potential for male harm. We then analyse a series of demographically explicit models, to assess how dispersal, overlapping generations, reproductive skew and the mechanism of population regulation affect sexual conflict across the genome, and drive conflict between nuclear and cytoplasmic genes. We then explore the effects of sex biases in these demographic parameters, showing how they may drive further conflicts between autosomes and sex chromosomes. Finally, we outline how different crossing schemes may be used to identify signatures of these intragenomic conflicts.

Nollywood to grow at expense of Nigeria startups

Significance Its broader success is being amplified by streaming services, most notably Netflix, which provides a platform for Nollywood to go global and attract foreign investment. These streaming services allow film producers to make more money from licensing rights than they have from the local cinema distribution model, and attract more foreign investment. Impacts Local distributors will have to revise their business models or risk being priced out of the market. Domination of the streaming market by Netflix may hurt local competition in the film industry and related startup economy. Splits may develop between low-cost producers aimed at local markets and high-cost ones aimed at global streaming markets.

Subnational Turnover, Accountability Politics, and Electoral Authoritarian Survival: Evidence from Museveni's Uganda

Most non-democratic regimes engineer elections such that regime change is effectively impossible via the ballot. However, many of these elections see high turnover of politicians at the subnational level, often through competitive processes that occur within ruling parties. This is the case for President Yoweri Museveni's dominant National Resistance Movement (NRM) in Uganda, the ranks of which have been decimated by intra-party competition at each election throughout its three decades in power. This competition includes high levels of voter participation in mass primaries and general elections and is particularly acute in the rural southern areas where Museveni's simultaneous presidential candidacy draws most support. Based on qualitative data from the 2016 elections, this article investigates the relationship between this local, intra-party competition and Museveni's survival, building a theory that local competition in electoral authoritarian regimes can provide an outlet for accountability politics by redirecting widespread voter frustrations away from a regime and towards expendable local politicians.

The Politics of Decentralization: Competition in Land Administration and Management in Ghana

Decentralization policy forms part of a broader global ideology and effort of the international donor community in favor of subsidiarity and local participation, and represents a paradigm shift from top-down command-and-control systems. Since 2003, the formalization of property rights through titling became an integral component of decentralized land administration efforts in Ghana. The creation of new forms of local government structures and the related changes in the distribution of responsibilities between different levels of government have an impact on natural resource management, the allocation of rights, and the unequal distribution of powers. This paper aims to understand how decentralization reforms modify the balance of power between public administration, customary authorities, and resource end-users in Ghana. Decentralization’s impact is analyzed based on two case studies. Relying on purposive and snowball sampling techniques, and mixed methods, we conducted 8 key informant interviews with local government bureaucrats in land administration, 16 semi-structured interviews with allodial landholders, 20 biographic interviews and 8 focus group discussions with small-scale farmers. The interviews analyzed the institutions and the roles of actors in land administration. Our case studies show that decentralization has the tendency to increase local competition in land administration where there are no clear distribution of power and obligation to local actors. Local competition and elitism in land administration impact the ability of small-scale farmers to regularize or formalize land rights. Thus, the paper concludes that local competition and the elitism within the land administration domain in Ghana could be the main obstacles towards decentralization reforms.

Understanding message (de)coding in multi-lingual slogans: industrial perspectives from Turkey and Russia

PurposeThe main goal of the study is to investigate how same-brand slogans simultaneously in use in two emerging markets, namely Turkey and Russia, differ semantically. The study further examines in what ways the industrial competition structure impacts the semantic slogan design within these two contexts.Design/methodology/approachThe study uses the method of semantic explication that is based on a 19-device taxonomy. This method is applied to 56 slogan pairs in the Turkish and Russian languages launched for the same brands/products across 6 industries.FindingsResults indicate that same-brand slogans differ semantically between Turkey and Russia. Moreover, firms tend to conform to a shared semantic pattern within a given industry, largely depending on the industrial competition structure. While strong local competition (as in the electronics and cleaning products industries in Turkey and in the personal care and beverages industries in Russia) leads firms to use self-reference, international competition (as in the automotive, personal care and beverages industries in Turkey and in the electronics and cleaning products industries in Russia) promotes them to use hyperbole in their slogan design.Practical implicationsAdopting a common semantic pattern within an industry may carry the risk of restricting brand differentiation and consumers' sense of novelty. Furthermore, the inclusion of brand names in slogans may make slogans sound assertive and lead consumers to overreact to the brand.Originality/valueUnlike many studies exploring different-brand slogans through a syntactic or grammatical lens, this study investigates the semantic features of same-brand slogans launched in two emerging market contexts. It adopts a B2B perspective, unlike many extant studies that often focus on a B2C one.

Eradicating Poverty in India by Sun using Dye Sensitized Photovoltaic Technology

Almost all 1.6 billion people in developing countries have no access to electricity; approximately 85% of the people live in rural areas. Poor people and people in marginal areas, presently depend on natural resources such as wood, charcoal, dung etc. to provide energy for cooking and heating. By 2030, in this category is expected to rise from 2.4 to 2.6 billion people. The result will be greater local competition for traditional energy. So, the rural development can be achieved by promoting locally available renewable energy to meet the basic electricity needs. Decentralised production units are appropriate wherever locally renewable sources of energy are available. Efficient use of traditional and commercial fuels. The main focus of this paper is to present the energy management techniques and different applications of solar energy utilization for the rural people in India to eradicate the poverty in addition to this the role of youth, educationalists, researchers, scientists, politicians and bureaucrats etc. to eradicating poverty in the nation.
