Modeling the variability of shapes of a human placenta

While it is well-understood what a normal human placenta should look like, a deviation from the norm can take many possible shapes. In this paper we propose a mechanism for this variability based on the change in the structure of the vascular tree

Universal behavior of localization of residue fluctuations in globular proteins

Localization properties of residue fluctuations in globular proteins are studied theoretically by using the Gaussian network model. Participation ratio for each residue fluctuation mode is calculated. It is found that the relationship between participation ratio and frequency is similar for all globular proteins, indicating a universal behavior in spite of their different size, shape, and architecture.Comment: 4 pages, 3 figures.

Perfect weddings abroad

Approximately 16% of UK couples are currently married abroad. However, academic or practitioner focused research that explores the complex nature of a couple’s buying preferences or the development of innovative marketing strategies by businesses operating within the weddings abroad niche sector, is almost non-existent. This exploratory paper examines the role and relevance of marketing within the weddings abroad sector. The complex nature of customer needs in this high emotional and involvement experience, are identified and explored. A case study of Perfect Weddings Abroad Ltd highlights distinctive features and characteristics. Social networking and the use of home-workers, with a focus on reassurance and handholding are important tools used to develop relationships with customers. These tools and techniques help increase the tangibility of a weddings abroad package. Clusters of complementary services that are synergistic and provide sources of competitive advantage are identified and an agenda for future research is developed

Molecular dynamics simulation of polymer helix formation using rigid-link methods

Molecular dynamics simulations are used to study structure formation in simple model polymer chains that are subject to excluded volume and torsional interactions. The changing conformations exhibited by chains of different lengths under gradual cooling are followed until each reaches a state from which no further change is possible. The interactions are chosen so that the true ground state is a helix, and a high proportion of simulation runs succeed in reaching this state; the fraction that manage to form defect-free helices is a function of both chain length and cooling rate. In order to demonstrate behavior analogous to the formation of protein tertiary structure, additional attractive interactions are introduced into the model, leading to the appearance of aligned, antiparallel helix pairs. The simulations employ a computational approach that deals directly with the internal coordinates in a recursive manner; this representation is able to maintain constant bond lengths and angles without the necessity of treating them as an algebraic constraint problem supplementary to the equations of motion.Comment: 15 pages, 14 figure

OrgML - a domain specific language for organisational decision-making

Effective decision-making based on precise understanding of an organisation is critical for modern organisations to stay competitive in a dynamic and uncertain business environment. However, the state-of-the-art technologies that are relevant in this context are not adequate to capture and quantitatively analyse complex organisations. This paper discerns the necessary information for an organisational decision-making from management viewpoint, discusses inadequacy of the existing enterprise modelling and specification techniques, proposes a domain specific language to capture the necessary information in machine processable form, and demonstrates how the collected information can be used for a simulation-based evidence-driven organisational decision-making

The media use of diaspora in a conflict situation : A case study of Venezuelans in Finland

Many Venezuelan emigrants have an emotional connection and/or they have family members and friends in the country of origin, and that is why they seek to find reliable information on the conflict situation in Venezuela. Therefore, they keep in touch with family members, read mainstream news and use different social media platforms. Thus, what kind of impact the conflict has on the media use and how events reported in the media are interpreted is investigated in this study of Venezuelan diaspora in Finland by using social media ethnography. There are internal and external factors behind the media use. External factors come from societies of the host and origin countries. Internal factors rise from family connections and identity construction concerning personal national identity or political activism.Peer reviewe

Are There Moral Limits to Wage Inequality?

Income inequality in democratic societies with market economies is sizable and growing. One reason for this growth can be traced to unequal forms of compensation that employers pay workers. Democratic societies have tackled this problem by enforcing a wage standard that all workers are paid regardless of education, skills, or contribution. This raises a novel question: Should there be equal pay for all workers? To answer it, we need to investigate some factors that are relevant to the unequal conditions of power and authority in which wage offers are made. By clarifying these, we can determine whether wage inequality is morally permissible. If not, then a case might be made to pay all workers the same regardless of education, skills, or contribution. Even if it is permissible, another question worth considering is whether there are limits to how much inequality is acceptable. The argument here proceeds along the following lines. First, I summarize the economic and non-economic factors that determine the value of wages in labor markets. Second, I examine a particular problem that concerns whether the conditions of wage labor are coercive because they restrict alternatives or otherwise include threats to the welfare of workers. If there is coercion, we have good reasons to establish a standard that improve these conditions. Finally, I claim that establishing this standard requires increasing the value of low-wage work. Doing so will not only expand alternatives that are available to these workers, it will also diminish the potential threat to their welfare

"Yay, Another Lady Starting a Log!": Women's Fitness Doping and the Gendered Space of an Online Doping Forum

This study aims to investigate and dissect the meanings attached to women’s use of performance and image enhancing drugs (PIEDs), how fitness doping can be understood in terms of gender and spatiality, and what implications this has for women’s communicative engagement with one another within an online forum. The study is based on a netnographic and qualitative methodology. Theoretically, it considers a women’s online forum for PIEDs and analyzes it as a community of practice (CofP) and a spatiality in which gender, bodies, and side effects are discussed and negotiated. The results show that although the women’s forum provides a space for women to share their own unique experiences, there is a limit to the extent to which the discussions mirror the experiences and experimentations of women. Instead, discussions are often dominated by men’s voices/experiences. This has two main implications. Firstly, the prevalence of men’s voices can block the development of a women’s CofP. Symbolically, men engage in a sort of cultural manspreading by encroaching on the women’s forum space. Secondly, it has implications for women’s PIED use and use practices. Women seeking out advice or the experiences of other women must navigate through and around men’s contributions
