Polyaromatic hydrocarbons in sediments from the Barents and White Seas

Polycyclic aromatic hydrocarbons (PAHs) are common environmental contaminants which can be derived from anthropogenic sources, such as combustion and discharges from extraction and transport, and natural processes, including leakage and erosion of fossil carbon. Natural PAH sources contribute, along with biological activities and terrestrial run-off, to the organic carbon content in sediments.The Barents Sea region is far from many anthropogenic sources of PAH, but production and trans-shipment of hydrocarbons is increasing. We present data for polycyclic aromatic hydrocarbon (PAH) concentrations in bottom sediments from 510 stations in the Barents and White Seas, and along the northern coast of Norway.

Discovery, structure and biological activities of the cyclotides

The cyclotides are a family of small disulfide rich proteins that have a cyclic peptide backbone and a cystine knot formed by three conserved disulfide bonds. The combination of these two structural motifs contributes to the exceptional chemical, thermal and enzymatic stability of the cyclotides, which retain bioactivity after boiling. They were initially discovered based on native medicine or screening studies associated with some of their various activities, which include uterotonic action, anti-HIV activity, neurotensin antagonism, and cytotoxicity. They are present in plants from the Rubiaceae, Violaceae and Cucurbitaccae families and their natural function in plants appears to be in host defense: they have potent activity against certain insect pests and they also have antimicrobial activity. There are currently around 50 published sequences of cyclotides and their rate of discovery has been increasing over recent years. Ultimately the family may comprise thousands of members. This article describes the background to the discovery of the cyclotides, their structural characterization, chemical synthesis, genetic origin, biological activities and potential applications in the pharmaceutical and agricultural industries. Their unique topological features make them interesting from a protein folding perspective. Because of their highly stable peptide framework they might make useful templates in drug design programs, and their insecticidal activity opens the possibility of applications in crop protection.

Three essays on a longitudinal analysis of business start-ups using the Kauffman Firm Survey

This dissertation focused on the longitudinal analysis of business start-ups using three waves of data from the Kauffman Firm Survey. ^ The first essay used the data from years 2004-2008, and examined the simultaneous relationship between a firm's capital structure, human resource policies, and its impact on the level of innovation. The firm leverage was calculated as, debt divided by total financial resources. Index of employee well-being was determined by a set of nine dichotomous questions asked in the survey. A negative binomial fixed effects model was used to analyze the effect of employee well-being and leverage on the count data of patents and copyrights, which were used as a proxy for innovation. The paper demonstrated that employee well-being positively affects the firm's innovation, while a higher leverage ratio had a negative impact on the innovation. No significant relation was found between leverage and employee well-being.^ The second essay used the data from years 2004-2009, and inquired whether a higher entrepreneurial speed of learning is desirable, and whether there is a linkage between the speed of learning and growth rate of the firm. The change in the speed of learning was measured using a pooled OLS estimator in repeated cross-sections. There was evidence of a declining speed of learning over time, and it was concluded that a higher speed of learning is not necessarily a good thing, because speed of learning is contingent on the entrepreneur's initial knowledge, and the precision of the signals he receives from the market. Also, there was no reason to expect speed of learning to be related to the growth of the firm in one direction over another.^ The third essay used the data from years 2004-2010, and determined the timing of diversification activities by the business start-ups. It captured when a start-up diversified for the first time, and explored the association between an early diversification strategy adopted by a firm, and its survival rate. A semi-parametric Cox proportional hazard model was used to examine the survival pattern. The results demonstrated that firms diversifying at an early stage in their lives show a higher survival rate; however, this effect fades over time.^

Temporary contracts and non-protected employment in Argentina, Chile and Perú: incidence and determinants

The diverse kinds of legal temporary contracts and the employment forms that do not comply with legal requirements both facilitate employment adjustment to firms´ requirements and entail labour cost reductions. Their employment incidence depends not only on the economic and labour market evolutions but also on other factors, in particular the historical trajectories followed by labour legislation, state enforcement, and the degree of compliance. To contribute to the understanding of the determinants of the degree of utilization of different employment practices, the study reported in this article explores the use made of the various legal temporary contracts and of precarious employment relationships by private enterprises in three Latin American countries (Argentina, Chile and Peru) during 2003-2012, a period of economic growth, and the explanatory role of diverse factors.

The impact of political and economic crisis on the polarization of the Spanish media

In this paper the characteristics of the cyclical political polarization of the Spanish media system are defined. From this study, a prospective analysis raises doubts about this scenario remains unchanged because of the political and economic crisis. It seeks to define the role played by political and media actors in polarization focusing on the two legislatures where the tension reached higher levels (1993-1996 and 2004-2008) and compares it with the developments faced by them in the current economical and political context of crisis. To achieve these aims, it has been performed an analysis of media content (since 1993) and looked through primary sociological sources and the scientific literature about polarization. This is an exploratory, critical and descriptive case analysis.

Latina Super-heroines: Hot Tamales in Tights vs. Women Warriors, Wrestlers and Guerrilla Fighters of La Raza

The year 1977 saw the making of the first Latino superhero by a Latino artist. From the 1980s onwards it is also possible to find Latina super-heroines, whose number and complexity has kept increasing ever since. Yet, the representations of spandexed Latinas are still few. For that reason, the goal of this paper is, firstly, to gather a great number of Latina super-heroines and, secondly, to analyze the role that they have played in the history of American literature and art. More specifically, it aims at comparing the spandexed Latinas created by non-Latino/a artists and mainstream comic enterprises with the Latina super-heroines devised by Latino/a artists. The conclusion is that whereas the former tend to conceive heroines within the constraints of the logic of Girl Power, the latter choose to imbue their works with a more daring political content and to align their heroines with the ideologies of Feminism and Postcolonialism.

Cultura e clima organizacionais: um estudo multicasos em indústrias de laticínios do estado do Rio Grande do Norte

The objective of this study is to investigate if exist relationship between organizational culture and the organizational climate, having as research s locus three dairy industries in the Rio Grande do Norte State. As such, an exploratory-descriptive and conclusive-causal study, with a sample composed of 211 employees of all firms hierarchical levels was undertaken. By way the data collection, the employees personal characteristics, the predominant organizational culture profile and the predominant organizational climate in the industries researched were identified. In order to analyse the organizational culture, the Competing Value Model (CAMERON; QUINN, 2006), with adaptations by Santos (1998, 2000), was used. In order to analyse the organizational climate, the Organizational Climate Measurement Scale, proposed by Martins (et al., 2004, 2008), with modifications, was used. The data were submitted to quantitative statistical analyses, firstly to the set of firms and afterwards to the firms alone, that permitted arrival to the following conclusions: the cultural profiles was met in a balanced way in the researched organizations, with emphasis to clan culture and market culture profiles; the researched organizations have a good organizational climate, based in the Martins (2008) classification, with emphasis to boss and organization s support and physical comfort , being these factors coherent whit the clan culture profile; the personal variables are correlated with the cultural profiles and with the organizational climate factors, however, each organization show its singular form of relation; and the cultural profiles showed influence on organizational climate factors. Thus, the results permitted to conclude that there are relations between the cultural profiles and the organizational climate factors in the researched organizations

Poliittisen vallan jakautuminen Kurikan ja Jurvan kuntaliitoksessa

Kuntaliitos tuo kuntien toimintaan ja niiden asukkaiden elämään monenlaisia muutoksia. Yksi vähäisimmistä ei ole liitoksen vaikutus edustuksellisen demokratian toteutumiseen: kunnan luottamustehtävät vähenevät, kilpailu niistä kiristyy ja valta jakautuu uudella tavalla. Tässä tutkielmassa asiaa on lähestytty vallan maantieteellisen jakautumisen ja kunnan eri osien alueellisen edustavuuden näkökulmasta. Vallan ja edustuksen mittareina toimivat kunnalliset luottamuspaikat valtuustossa, hallituksessa ja muissa kunnan toimielimissä. Lisäksi on selvitetty poliittisten päättäjien näkemyksiä kuntaliitoksen jälkeisestä vallankäytöstä ja liitoksen hyödyistä ja haitoista. Kyseessä on tapaustutkimus vuoden 2009 alussa toteutuneesta Kurikan ja Jurvan kuntaliitoksesta. Aineistona ovat vuosien 2004, 2008 ja 2012 kunnallisvaalien tulokset, kuntahallinnon pöytäkirjat sekä tutkimuskuntien 19 pitkäaikaisen luottamushenkilön haastattelut. Tilasto- ja asiakirja-aineiston analysoinnissa on käytetty tilastollisia perusmenetelmiä, luokittelua ja taulukointia. Haastatteluaineisto on kerätty puhelimitse strukturoituna lomakehaastatteluna ja sitä on analysoitu kuvailun, luokittelun ja dikotomisen ristiintaulukoinnin avulla. Tutkielman teoreettisen viitekehyksen rakennuspuina toimivat yhtäältä kunnat, kuntarakenne ja kuntaliitostutkimus, toisaalta valta ja edustuksellisen demokratian instituutiot ja kolmantena poliittinen maantiede ja vaalimaantiede. Tutkimuksen lähtökohtana toimii kuntaliitoskuntien kunnallisvaaleja koskeva aiempi valtakunnallinen tutkimus, jonka mukaan kuntaliitosten reuna-alueet ovat usein vaaleissa saaneet kokoaan suuremman edustuksen uuden kunnan valtuustoon. Alueellinen edunvalvonta kunnallisvaaleissa tiivistyy ehdokasasetteluun, äänten keskittämiseen ja alueperustaiseen äänestämiseen. Tutkimuksen tulokset osoittavat, että Kurikan ja Jurvan kuntaliitoksen jälkeen kunnan poliittinen valta ei ole jakautunut tasapuolisesti, vaan jurvalaiset ovat olleet luottamuselimissä yliedustettuina. Keskeiset syyt yliedustukseen löytyvät ehdokasasettelusta ja äänten onnistuneesta keskittämisestä. Haastattelujen tulokset osoittavat selkeitä eroja kurikkalaisten ja jurvalaisten päättäjien käsityksissä koskien vallan jakautumista, käyttöä ja kuntaliitoksen alueellisia vaikutuksia.

The antecedents of post-initial adoption behavior in a S-D logic context

Repercussions of innovation adoption and diffusion studies have long been imperative to the success of novel introductions. However, perceptions and deductions of current innovation understandings have been changing over time. The paradigm shift from the goods-dominant (G-D) logic to the service-dominant (S-D) logic potentially makes the distinction between product (goods) innovation and service innovation redundant as the S-D logic lens views all innovations as service innovations (Vargo and Lusch, 2004; 2008; Lusch and Nambisan, 2015). From this perspective, product innovations are in essence service innovations, as goods serve as mere distribution mechanisms to deliver service. Nonetheless, the transition to such a broadened and transcending view of service innovation necessitates concurrently a change in the underlying models used to investigate innovation and its subsequent adoption. The present research addresses this gap by engendering a novel model for the most crucial period of service diffusion within the S-D logic context – the post-initial adoption phase, which demarcates an individual’s behavior after the initial adoption decision of a service. As a wellfounded understanding of service diffusion and the complementary innovation adoption still lingers in its infancy, the current study develops a model based on interdisciplinary domains mapping. Here fore, knowledge of the relatively established viral source domain is mapped to the comparatively undetermined target domain of service innovation adoption. To assess the model and test the importance of the explanatory variables, survey data from 750 respondents of a bank in Northern Germany is scrutinized by means of Structural Equation Modeling (SEM). The findings reveal that the continuance intention of a customer, actual usage of the service and the customer influencer value all constitute important postinitial adoption behavior that have meaningful implications for a successful service adoption. Second, the four constructs customer influencer value, organizational commitment, perceived usefulness and service customization are evidenced to have a differential impact on a iv customer’s post-initial adoption behavior. Third, this study indicates that post-initial adoption behavior further underlies the influence of a user’s age and besides that is also provoked by the internal and external environments of service adoption. Finally, this research amalgamates the broad view of service innovation by Nambisan and Lusch (2015) with the findings ensuing this enquiry’s model to arrive at a framework that it both, generalizable and practically applicable. Implications for academia and practitioners are captured along with avenues for future research.
