A large percentage of the industrial SMEs has an organizational structure for product development too far from the adequate practices and models, elaborated by renowned authors with expertise in the theme of product development. On the other hand, the authors state that SMEs obtain considerable advantages by adopting a model of product development process (PDP) management. Healt is one of the most innovative sectors in the world, and countries like Brazil and Colombia are transitioning from a system that cares for contagious infecttions diseases where the drug product is the main form of treatment - to a system that cares for chronic degenerative conditions - where the equipment, including hospital furniture, has more relevance to the treatment. This change is offering better opportunities of specialized markets to hospital furniture SMEs that adopt an adquate PDF model. The present study proposes a first outline of a model of PDP management for industrial metal-mechanical SMEs that develop and manufacture hospital furniture, from a review of models proposed for great mechanical area.

[ES] Los graves problemas territoriales existentes en Canarias han motivado un continuo desarrollo normativo autonómico desde los ochenta que culminó con la aprobación en 2000 de un Texto Refundido de las leyes de ordenación del territorio en el que se intentó estructurar jerárquicamente la ordenación territorial, el planeamiento urbanístico y la protección de los espacios naturales. Además de dotarse con instrumentos propios de ordenación, la presente década se ha caracterizado por la definición normativa de un modelo de desarrollo sostenible a través de la formulación de unas Directrices de ordenación. En este artículo abordamos el análisis de las características de la ordenación territorial en Canarias y del modelo de desarrollo promulgado, con el fin de manifestar su escasa capacidad de intervención al mismo tiempo que aportamos una reflexión sobre las nuevas orientaciones anti-cíclicas aprobadas recientemente y que pueden suponer el desmoronamiento de parte del modelo de desarrollo construido en la presente década.

Zusammenfassung Ein 3-dimensionales globales Modell der unterenAtmosphäre wurde für die Untersuchung derOzonchemie, sowie der Chemie des Hydroxylradikals (OH) undwichtiger Vorläufersubstanzen, wie reaktiverStickstoffverbindungen und Kohlenwasserstoffe, verwendet.Hierfür wurde die Behandlung vonNicht-Methan-Kohlenwasserstoffen (NMKW) hinzugefügt,was auch die Entwicklung einer vereinfachten Beschreibungihrer Chemie, sowie die Erfassung von Depositionsprozessenund Emissionen erforderte. Zur Lösung der steifengewöhnlichen Differentialgleichungen der Chemie wurdeeine schnelles Rosenbrock-Verfahren eingesetzt, das soimplementiert wurde, dass die Modell-Chemie fürzukünftige Studien leicht abgeändert werden kann. Zur Evaluierung des Modells wurde ein umfangreicherVergleich der Modellergebnisse mit Bodenmessungen, sowieFlugzeug-, Sonden- und Satelliten-Daten durchgeführt.Das Modell kann viele Aspekte der Beobachtungen derverschieden Substanzen realistisch wiedergeben. Es wurdenjedoch auch einige Diskrepanzen festgestellt, die Hinweiseauf fehlerhafte Emissionsfelder oder auf die Modell-Dynamikund auch auf fehlende Modell-Chemie liefern. Zur weiteren Untersuchung des Einflusses verschiedenerStoffgruppen wurden drei Läufe mit unterschiedlichkomplexer Chemie analysiert. Durch das Berücksichtigender NMKW wird die Verteilung mehrerer wichtiger Substanzensignifikant beeinflusst, darunter z.B. ein Anstieg desglobalen Ozons. Es wurde gezeigt, dass die biogene SubstanzIsopren etwa die Hälfte des Gesamteffekts der NMKWausmachte (mehr in den Tropen, weniger anderswo). In einer Sensitivitätsstudie wurden die Unsicherheitenbei der Modellierung von Isopren weitergehend untersucht.Dabei konnte gezeigt werden, dass die Unsicherheit beiphysikalischen Aspekten (Deposition und heterogene Prozesse)ebenso groß sein kann, wie die aus dem chemischenGasphasen-Mechanismus stammende, welche zu globalbedeutsamen Abweichungen führte. Lokal können sichnoch größere Abweichungen ergeben. Zusammenfassend kann gesagt werden, dass die numerischenStudien dieser Arbeit neue Einblicke in wichtige Aspekte derPhotochemieder Troposphäre ergaben und in Vorschläge fürweiter Studien mündeten, die die wichtigsten gefundenenUnsicherheiten weiter verringern könnten.

This doctoral thesis unfolds into a collection of three distinct articles that share an interest in supply firms, or “peripheral firms”. The three studies offer a novel theoretical perspective that I call the peripheral view of manufacturing networks. Building on the relational view literature, this new perspective identifies the supplier-based theoretical standpoint to analyze and explain the antecedents of relational rents in manufacturing networks. The first article, the namesake of the dissertation, is a theoretical contribution that explains the foundations of the “peripheral view of manufacturing networks”. The second article “Framing The Strategic Peripheries: A Novel Typology of Suppliers” is an empirical study with the aim to offer an interpretation of peripheries’ characteristics and dynamics. The third article, “What is Behind Absorptive Capacity? Dispelling the Opacity of R&D” presents an example of general theory development by using data from peripheral firms.

The carbonate outcrops of the anticline of Monte Conero (Italy) were studied in order to characterize the geometry of the fractures and to establish their influence on the petrophysical properties (hydraulic conductivity) and on the vulnerability to pollution. The outcrops form an analog for a fractured aquifer and belong to the Maiolica Fm. and the Scaglia Rossa Fm. The geometrical properties of fractures such as orientation, length, spacing and aperture were collected and statistically analyzed. Five types of mechanical fractures were observed: veins, joints, stylolites, breccias and faults. The types of fractures are arranged in different sets and geometric assemblages which form fracture networks. In addition, the fractures were analyzed at the microscale using thin sections. The fracture age-relationships resulted similar to those observed at the outcrop scale, indicating that at least three geological episodes have occurred in Monte Conero. A conceptual model for fault development was based on the observations of veins and stylolites. The fracture sets were modelled by the code FracSim3D to generate fracture network models. The permeability of a breccia zone was estimated at microscale by and point counting and binary image methods, whereas at the outcrop scale with Oda’s method. Microstructure analysis revealed that only faults and breccias are potential pathways for fluid flow since all veins observed are filled with calcite. According this, three scenarios were designed to asses the vulnerability to pollution of the analogue aquifer: the first scenario considers the Monte Conero without fractures, second scenario with all observed systematic fractures and the third scenario with open veins, joints and faults/breccias. The fractures influence the carbonate aquifer by increasing its porosity and hydraulic conductivity. The vulnerability to pollution depends also on the presence of karst zones, detric zones and the material of the vadose zone.

The Environmental Health (EH) program of Peace Corps (PC) Panama and a non-governmental organization (NGO) Waterlines have been assisting rural communities in Panama gain access to improved water sources through the practice of community management (CM) model and participatory development. Unfortunately, there is little information available on how a water system is functioning once the construction is complete and the volunteer leaves the community. This is a concern when the recent literature suggests that most communities are not able to indefinitely maintain a rural water system (RWS) without some form of external assistance (Sara and Katz, 1997; Newman et al, 2002; Lockwood, 2002, 2003, 2004; IRC, 2003; Schweitzer, 2009). Recognizing this concern, the EH program director encouraged the author to complete a postproject assessment of the past EH water projects. In order to carry out the investigation, an easy to use monitoring and evaluation tool was developed based on literature review and the author’s three years of field experience in rural Panama. The study methodology consists of benchmark scoring systems to rate the following ten indicators: watershed, source capture, transmission line, storage tank, distribution system, system reliability, willingness to pay, accounting/transparency, maintenance, and active water committee members. The assessment of 28 communities across the country revealed that the current state of physical infrastructure, as well as the financial, managerial and technical capabilities of water committees varied significantly depending on the community. While some communities are enjoying continued service and their water committee completing all of its responsibilities, others have seen their water systems fall apart and be abandoned. Overall, the higher score were more prevalent for all ten indicators. However, even the communities with the highest scores requested some form of additional assistance. The conclusion from the assessment suggests that the EH program should incorporate an institutional support mechanism (ISM) to its sector policy in order to systematically provide follow-up support to rural communities in Panama. A full-time circuit rider with flexible funding would be able to provide additional technical support, training and encouragement to those communities in need.

The purpose of this project is to take preliminary steps towards the development of a QUAL2Kw model for Silver Bow Creek, MT. These preliminary steps include initial research and familiarization with QUAL2Kw, use of ArcGIS to fill in geospatial data gaps, and integration of QUAL2Kw and ArcGIS. The integration involves improvement of the QUAL2Kw model output through adding functionality to the model itself, and development of a QUAL2Kw specific tool in ArcGIS. These improvements are designed to help expedite and simplify the viewing of QUAL2Kw output data spatially in ArcGIS as opposed to graphically within QUAL2Kw. These improvements will allow users to quickly and easily view the many output parameters of each model run geographically within ArcGIS. This will make locating potential problem areas or “hot spots” much quicker and easier than interpreting the QUAL2Kw output data from a graph alone. The added functionality of QUAL2KW was achieved through the development of an excel Macro, and the tool in ArcGIS was developed using python scripting and the model builder feature in ArcGIS.

This article explores societal culture as an antecedent of public service motivation. Culture can be a major factor in developing an institution-based theory of public service motivation. In the field of organization theory, culture is considered a fundamental factor for explaining organization behavior. But our review of the literature reveals that culture has not been fully integrated into public service motivation theory or carefully investigated in this research stream. This study starts to fill this gap in the literature by using institutionalism and social-identity theory to predict how the sub-national Germanic and Latin cultures of Switzerland, which are measured through the mother tongues of public employees and the regional locations of public offices, affect their levels of public service motivation. Our analysis centers on two large data sets of federal and municipal employees, and produces evidence that culture has a consistent impact on public service motivation. The results show that Swiss German public employees have a significantly higher level of public service motivation on the whole, while Swiss French public employees have a significantly lower level overall. Implications for theory development and future research are discussed.

This contribution focuses on the characteristics of the school context and their impact on immigrant students’ acculturation and adjustment at school. Research suggests that the ways immigrants acculturate is related to their well being (e.g. Phinney, et al., 2001; Ward & Rana-Deuba, 1999), although findings have been contradictory across methods and studies (e.g. Rogler, 1991; Escobar & Vega, 2001). Debates in acculturation research currently center on issues of acculturation measurement (e.g. Berry, 2009; Rudmin, 2009), as most research is conducted in the quantitative tradition. In addition, some have suggested (Birman, 2011) that research on acculturation in the tradition of cross-cultural psychology adopts an overly individualistic perspective, and lacks attention to the specific contexts of acculturation. Alternatively, the contextual approach proposes that the relationship between acculturation and adjustment is shaped by the surrounding context (Birman & Simon, 2013). For immigrant children, schools are the setting where the process of acculturation unfolds, and an important context in which to study their adjustment and well being (Birman, et al., 2007; Makarova & Herzog, 2011). Though rarely used in this tradition of acculturation research (Chirkov, 2009), qualitative methods are uniquely suited to gain insight to facilitate theory development, as well as appreciate the contextual nature of the acculturation process. Yet we are not aware of efforts to synthesize the empirical qualitative literature on this topic. Applying the methodology of meta-synthesis for qualitatieve research (Walsh & Downe, 2005) our contribution attempts to integrate results from qualitative studies on impact of acculturation on immigrant students’ psychological adjustment in the school context. For this purpose 84 articles which matched the inclusion criteria were selected. Overall, the results of our study show that within the school context a number of structural as well as process characteristics can be identified as crucial for immigrant youth psychological adjustment. Moreover, our findings indicate that immigrant youths’ psychological adjustment is related to other individual outcomes of acculturation in the school context such as behavioral adjustment, peer-relationships, academic achievement and identity development of immigrant youth.

The paper is a comparative inquiry into the roles of Ilia Chavchavadze (1837-1907) and Taras Shevchenko (1818-1861) as national poets and anti-colonial (anti-Tsarist) intellectuals within the context of their respective national traditions (Georgia and Ukraine). During the period of their activity (19th and the beginning of 20th century) both Ukraine and Georgia were under Tsarist imperial rule, albeit the two poets lived in different periods of Russian empire history. Through their major works, each called on their communities to ‘awaken’ and ‘revolt’ against oppression, rejected social apathy caused by Tsarist subjugation and raised awareness about the historical past of their nations. The non-acceptance of present and belief in an independent future was one of the dominant themes in the poetry and prose of both. Their contemporary importance is illustrated in political discourse both after Orange Revolution in Ukraine (2004), and Rose Revolution in Georgia (2003) where both poets are referred “as founding fathers of national ideology”, the history textbooks alluding to them as “symbols of anti-colonial resistance”. To this day, however, there has been surprisingly little academic writing in the West endeavoring to compare the works and activities of the two poets and their impact on national mobilization in Tsarist Ukraine and Georgia, even though their countries are often mentioned in a same breath by commentators on contemporary culture and politics. The paper attempts to fill this gap and tries to understand the relationship between literature and social mobilization in 19th century Russian Empire. By reflecting on Taras Shevchenko’s and Ilia Chavchavadze’s poetry, prose and social activism, I will try to explain how in different periods of Russian imperial history, the two poets helped to develop a modern form of political belonging among their compatriots and stimulated an anti-colonial mobilization with different political outcomes. To theorize on the role of poets and novelists in anti-colonial national movement, I will reflect on the writings of Benedict Anderson (1991), John Hutchinson (1994; 1999), Rory Finnin (2005; 2011) and problematize Miroslav Hroch’s (1996) three phase model of the development of national movements. Overall, the paper would aim to show the importance of, what John Hutchinson called, ‘cultural nationalists’ in understanding contemporary nationalist discourse in Georgian and Ukrainian societies.

This study was designed to investigate and describe the relationship among resilience, forgiveness and anger expression in adolescents. The purpose of the study was to explore whether certain adolescent resiliencies significantly related to positive or negative affective, behavioral, or cognitive levels of forgiveness and certain types of anger expression in adolescents. This study also investigated whether there were certain adolescent resiliencies and types of forgiveness that can predict lower levels of negative anger expression in adolescents. This research was built on two conceptual models: Wolin and Wolin's (1993) Challenge Model and the Forgiveness Process Model (Enright & Human Development Study Group, 1991). It was based on a quantitative, single-subject correlational research design. A multiple regression analysis was also used to explore possible effects of resilience and forgiveness on anger expression in adolescents. In addition, two demographic variables, Age and Gender, were examined for possible effects on anger expression. Data were gathered from a convenience sample sample of 70 students in three Maine public high schools using three separate assessment instruments: the Adolescent Resiliency Attitudes Scale (ARAS), the Adolescent Version of the Enright Forgiveness Inventory (EFI), and the Adolescent Anger Rating Scale (AARS). Correlational analyses were done on the scales and subscales of these surveys. Significant relationships were found between several adolescent resiliencies and forms of forgiveness as well as between some adolescent resiliencies and types of anger expression. The data indicated that Total Resiliency significantly correlated with Total Forgiveness as well as Total Anger. The findings also identified particular adolescent resiliencies that significantly predicted types of anger expression, while forgiveness did not predict types of anger expression. The data revealed that Age and Gender had no significant affect on anger expression. These findings suggest that the constructs of adolescent resilience and forgiveness have commonalities that can influence how adolescents express anger, and further suggest that intervention and prevention programs expand their focus to incorporate forgiveness skills. The findings from this study can provide critical information to counselors, therapists, and other helping professionals working with adolescents, on approaches to designing and implementing therapy modalities or developmental school guidance programs for adolescents.

A review of literature related to appointment-keeping served as the basis for the development of an organizational paradigm for the study of appointment-keeping in the Beta-blocker Heart Attack Trial (BHAT). Features of the organizational environment, demographic characteristics of BHAT enrollees, organizational structure and processes and previous organizational performance variables were measured so as to provide exploratory information relating to the appointment-keeping behavior of 3,837 participants enrolled at thirty-two Clinical Centers. Results suggest that the social context of individual behavior is an important consideration for the understanding of patient compliance. In particular, the degree to which previous organizational performance--as measured by obtaining recruitment goals--and the ability to utilize resources had particularly strong bivariate associations with appointment-keeping. Implications for future theory development, research and practical implications were provided as was a suggestion for the development of multidisciplinary research efforts conducted within the context of Centers for the study and application of adherence behaviors. ^

El objetivo de este trabajo es discutir los enfoques principales del debate sobre el tratamiento que debe dar la economía al impacto ambiental. El tema se relaciona con toda la discusión sobre el desarrollo y sobre la relación entre territorio y desarrollo, y atraviesa la problemática de la geografía económica y regional en cuestiones como la planificación regional o el análisis de impacto, sobre todo en territorios con fuerte influencia de la explotación de recursos naturales. Se analiza la manera de incorporar el problema en las bases de la economía neoclásica aceptando sus principios y utilizando sus instrumentos. Luego se aborda la economía ecológica desde el trabajo de Georgescu-Roegen de 1971, el primero que intenta introducir en el razonamiento económico las leyes de la irreversibilidad de los procesos, por fuera de la visión neoclásica y fundando una corriente heterodoxa. Más allá de estas posiciones, están las visiones que analizan la relación entre ambiente y desarrollo manteniendo el concepto de centro-periferia o asumiendo la necesidad de construir discursos contra-hegemónicos, enmarcando la cuestión ambiental en esa lógica: se mencionan la postura del marxismo y el aporte del poscolonialismo -este último, fundamental, por la importancia que asigna a la necesidad de reconstruir la perspectiva ambiental desde las identidades y el territorio-. Las conclusiones plantean el desafío de retomar este tipo de puntos de vista -lo que limita enormemente el uso del herramental de la economía ambiental- y también algunas propuestas neoinstitucionalistas de la economía ecológica
