Abstract: objective: to examine the psychometric performance of the scoff, a brief screening instrument for eating disorders (ed). materials and methods: mexican university applicants (n= 3594, 55.7% female, m age= 18.1 years) completed self-report measures and a health screen. results: confirmatory factor analyses revealed one factor for females. however a bifactor model fits better for males and females. reliability was lower for females (kr20 = .49) than males (kr20 = .59). more females (24.2%) presented risk for ed (scoff > 2) than males (11.2%). nomological validity indicated that risk for ed in young women was associated with demographic (e.g., parental education), psychological (e.g., depression, weight management efficacy), physical (e.g., bmi), and social (e.g., family conflict) indicators in conceptually coherent ways. fewer variables were significant for males. conclusion: although the scoff may be a useful ed screen in mexico, further research must examine its criterion validity, sensitivity, and specificity.

Abstract: The objective of this study is to analyze the relationship between the structural funds provided by the European Union (EU) and the real convergence of the New Member States that joined the EU in 2004. We also assess the effect of the crisis on this. According to the empirical studies in this area, the impact can be both negative and positive. Furthermore, in the latter case, the correlation is not very strong and depends on several factors. To meet the research objective, we have structured this paper into five parts. In the first part, we make a short presentation of the Cohesion policy and its evolution in time. In the second part, we explore the importance of the subject in the economic literature. In the third one, we explain the methodology used in this paper. We contribute to the literature by creating a Real Convergence Index (RCI) and by assessing the evolution of this index and of the structural funds payments from 2004 until 2010 in five New Member States (Hungary, the Czech Republic, Poland, Slovakia and Slovenia). The fourth part describes the results obtained. The structural funds payments reached a maximum level in 2007 in all the countries, with the exception of Slovenia. After this point, they recorded decreasing levels, mainly because of the economic and financial crisis. Within this group of countries, Poland and Slovakia recorded an increase in RCI during 2009 and 2010, even though the amounts of payments started decreasing. The highest level of structural funds payments and the maximum level of RCI are not synchronized, with the exception of the Czech Republic. This could come as a result of the lagging effects of structural funds on the economic convergence. The fifth part of the paper summarizes the conclusions of our research. The analysis confirms the previous work in this field. Specifically, it does not provide us with a clear result regarding the relationship between the absorption of structural funds and the real convergence. The implications for Romania are not very encouraging. This means that the efforts for increasing the absorption rate of EU funds will not necessarily lead to a faster real convergence process. Consequently, the effectiveness of the Cohesion policy remains under question.

Abstract: The objective of this paper is to examine how the current financial crisis has affected the fiscal discipline and convergence in the seven Central and Eastern European countries which have not yet joined the Euro Area (EA), namely Bulgaria, the Czech Republic, Hungary, Latvia, Lithuania, Poland and Romania. In the first part, we emphasize the importance of fiscal discipline for the effective functioning of the European Monetary Union (EMU). In the second part, by exploring the current status of the literature in this field, we identify scarce theoretical and empirical research on the non-EA countriesa€ fiscal discipline and convergence. In the third one, we briefly present the data and methodology used in the paper. We report the fiscal discipline of the non-EA countries by analysing their distance from the Maastricht criteria regarding the budgetary deficit and the public debt as shares of GDP in the fourth part. We also assess the fiscal convergence of the seven candidates for Euro adoption in order to understand whether they add to the strengths or to the weaknesses of the EMU, from a fiscal point of view, by employing two benchmarks: the EA core and the EA periphery. The sovereign debt crisis emphasized the asymmetry between core and periphery countries. It is of major importance to know if the EA candidates will exacerbate the fiscal imbalances by joining the periphery group of countries or by contrast, will promote fiscal discipline and sustainability alongside the core EA member states. The fifth part concludes. The non-EA group of countries has not experienced major fiscal imbalances in the last four years, but the efforts must continue in reducing the budgetary deficits and controlling the public debts. In times of crisis, the EA candidates achieved more convergence with the EA core than with the EA periphery, by reducing the distance from the EA core. This is due to a deterioration in the fiscal performance of the EA core states and not to an improvement in the non-EA group of countries. The result is not encouraging for the fiscal convergence given the fact that we would expect an improvement in the non-EA countriesa€ fiscal performance in order to catch-up with the best performers of the EA and not the reverse. In terms of public debt, the fiscal convergence with the EA core would not be desirable, due to the high levels of public debt achieved by these countries.
The Science of Leading Yourself: A Missing Piece in the Health Care Transformation Puzzle  [PDF]
Wiley W. Souba
Open Journal of Leadership (OJL) , 2013, DOI: 10.4236/ojl.2013.23006

Personal transformation is a prerequisite for sustainable transformation of our health care system. Integrating research from the language sciences, phenomenology, psychology and neurobiology, this article reviews the science of leading oneself. Because this “inward” journey can be alien and disorienting, the Language Leadership Performance Model is helpful in illustrating the relationship between the circumstances the leader is dealing with (the leadership challenge), the context (point of view) the leader brings to that challenge, and the leader’s way of being and acting (the definitive source of the leader’s performance). Using language, effective leaders reframe their leadership challenges such that their naturally correlated ways of being and acting provide them with new opportunity sets for exercising exemplary leadership. Using a house metaphor (The House of Leadership), a foundation for being a leader and a framework for exercising leadership are constructed. Laying the foundation of the model involves mastering the four pillars of being a leader. Erecting the framework entails building a contextual schema, which, when mastered, becomes a construct that in any leadership situation gives one the power to lead effectively as one’s natural self-expression. Both of these activities—laying the foundation and erecting the framework—involve a deconstruction of one’s existing leadership paradigm. Finally, A Heuristic for Leading Oneself is offered as a useful guide or owner’s manual as one embarks on this inward journey. Leading oneself is a uniquely human activity—studying it and how it works is a vital piece in solving the health care transformation puzzle.

The Phenomenology of Leadership  [PDF]
Wiley W. Souba
Open Journal of Leadership (OJL) , 2014, DOI: 10.4236/ojl.2014.34008

Teaching people about leadership is different from creating leaders. Teaching leadership uses a third-person approach to impart someone else’s knowledge, which grants learners limited direct access to the being and actions of effective leaders. In contrast, creating leaders entails a first-person phenomenological methodology, which provides direct access to what it means to be a leader and what it means to exercise good leadership in real time, with real results. The distinctiveness of the first-person “as-lived/lived-through” approach lies in its capacity to disclose the hidden contexts that shape the ways of being, thinking, and acting that are the source of the leader’s performance. When these contexts become unveiled, it allows for the creation of new contexts that give leaders more space and more degrees of freedom to lead effectively as their natural self-expression. A phenomenological inquiry into leadership does not study the attributes of leaders, but rather the fundamental structures of human “being” that make it possible to be a leader in the first place. Because the phenomenological “facts” of lived experience reside in language, creating for oneself what it is to be a leader entails mastering a special language (that includes terms like intentionality; thrownness; being-in-the-world; clearing-for-action; absorbed coping; hermeneutic; and, break-down) from which leaders can orient their being, thinking, and actions. Learning to be a leader is not first and foremost about the acquisition of knowledge or certain personal attributes. Rather, only when leadership becomes an as-lived/lived-through experience does it grant access to its actual nature and essence.

The Thrown Leader  [PDF]
Wiley Souba, Matthew Souba
Open Journal of Leadership (OJL) , 2017, DOI: 10.4236/ojl.2017.64010
The term “thrownness” designates our inevitable submission to life’s challenges and predicaments, often determined arbitrarily by chance or by destiny. We inescapably find ourselves thrown because the world matters to us in some way or another. The term has major implications for effective leadership since leaders are invariably thrown into vexing circumstances or inherit problems that they had nothing to do with creating in the first place. Effective leaders attend to and “throw off” their thrownness by choosing judiciously from those possibilities (actions) that are available to them in a particular situation. Our “being” as leaders is always a struggle between thrownness and possibility because the undertakings we engage in and the people we interact with—our students, our colleagues, and our families—matter to us in some way or another. We care about our future and the future of our work; that’s what makes the sting of being thrown so raw. But rather than avoiding or disengaging from their challenges, authentic leaders take responsibility for what was, what is, and what will be, regardless of the circumstances they are thrown into. Acceptance of the randomness and inevitability of being thrown, with its associated aggravations and annoyances, is a hallmark of effective leaders. This grants leaders a somewhat paradoxical gateway to freedom, a journey on which they can discover purpose in their thrown humanity.
Evaluation of TiO2, ZnO, CuO and Ga2O3 on the Photocatalytic Degradation of Phenol Using an Annular-Flow Photocatalytic Reactor  [PDF]

Abstract: Even with rigorous environmental regulations, phenol still is a major contaminant. One possible solution is the use of heterogeneous photocatalysis due to low chemical addition, feasibility and reliability to be implanted on cost-effective industrial process. TiO2 is the most employed photocatalyst because of its favorable (photo) chemical properties and ZnO is considered one of the best alternative for that. Other oxides were tested in lesser proportions, like CuO and Ga2O3. When the photocatalyst is dispersed as slurry, higher degradation rates are achieved due to high solid to liquid contact area when compared with supported form. The aim of this work was to develop a batch recirculating photocatalytic reactor and evaluate its efficiency when assisted by the photocatalysts TiO2 P25, ZnO, CuO and β-Ga2O3. TiO2 achieved 95% mineralization after 200 min reaction in an average degradation rate of 0.68 mg·L﹣1·min﹣1 and ZnO was less efficient (0.41 mg·L﹣1·min﹣1). Ga2O3 and CuO presented poor performance, mainly due to low surface area for the CuO syntesized and the absorption of the UV radiation by the reactor walls, decreasing Ga2O3 activity. Degradation intermediates were detected in diverse concentrations and at different operational times for each oxide tested, which indicate different degradation mechanisms.
Auto-incompatibilidade em Miconia ciliata (L.C.Rich.) DC. (Miconieae - Melastomataceae)
Melo, Gladys Flavia de;Machado, Isabel Cristina;
Acta Botanica Brasilica , 1998, DOI: 10.1590/S0102-33061998000200002
Abstract: miconia ciliata is a shrub whith flowers over a period of 11 months. the flowers are hermaphrodite with diurnal anthesis. probably miconia ciliata exhibits gametophytic incompatibility - pollen tube growth's interrupted in the style. bees of the family halictidae were observed to use the vibration technique to extract pollen (buzz pollination). only few flowers per inflorescence open each day. which probably induces the effective pollinators to visit a larger number of inflorescence in each individual plant, promoting cross pollination. reproductive success in miconia ciliata is favoured by the high frequency of pollinators visits, high p/o ration and high pollen fertility.

Abstract: during the last few decades, contract agriculture constitutes an agricultural integrating and subordinating mechanism to agribusiness expanding in third world countries. in mexico and more precisely in guanajuato, this work routine prevails around the production of cash crops that are frozen for export, uncommon in the cultivation of grains, except for the case of barley and a certain variety of wheat produced for cargill. with grains, another type of contractual relation predominates. the objective of the present article is to analyze the gambit of contractual relations established between producers (cash crops and grains) and agro industry in addition to the implications or impacts they have on both agents. as of the mid 80's, the structural adjustment policy applied in mexico has implied the retirement of the state from the area of production, commercialization and services in the agricultural cattle-producing sector. to this a severe crisis and an increase in the dependency of producers to agribusiness and intermediaries can be added. in this context, contractual relations such as contract agriculture are growing and represent the only survival alternative for an infinite number of grain and cash crop producers.
El maíz amarillo cultivado bajo contrato en México 2000-2005: Reflexiones sobre un programa de comercialización de granos
Cristina Steffen Riedemann,Flavia Echánove Huacuja
Cuadernos Geográficos , 2007,
Abstract: Más del 95% del maíz que se produce en México es blanco. En los últimos a os el Estado mexicano ha impulsado la agricultura por contrato de maíz amarillo con la finalidad de contribuir a la sustitución de las más de 5 millones de toneladas que se importan anualmente, volumen necesario para satisfacer la demanda del sector pecuario y de la industria de derivados alimenticios y químicos del maíz. Además busca reconvertir al maíz amarillo un porcentaje de la superficie sembrada con maíz blanco, grano este último que, según datos oficiales, se vería afectado por una sobreproducción estimada de más de 2 millones de toneladas. Los objetivos que se propone este trabajo son conocer las condiciones en que se está dando esta experiencia, valorar qué posibilidad de éxito y expansión tiene la agricultura bajo contrato en el caso del maíz amarillo ante un mercado totalmente abierto a partir del 2008 y explicar los efectos que tiene la producción bajo contrato de este grano en los distintos sujetos participantes.
