Global marketing : foreign entry, local marketing, & global management / Johny K. Johansson.
No full textIncludes bibliographical references and indexes.xix, 662 pages :Johansson’s Global Marketing, 5/e utilizes a three-pronged framework to organize the discussion of how to conduct global business: Foreign Entry, Local Marketing, and Global Management. Johansson seeks to develop the varied skills a marketing manager needs to be successful in each of these tasks. In foreign entry, in global management, and to a large extent even as a local marketer in a foreign country, the global marketer needs skills that the home makes experience-or the standard marketing text-have rarely taught. The recognition of the three roles helps dispel the notion that “there is no such thing as international global marketing, only marketing. Much of the excellent research and tried-and-true teaching material that global marketers in business and academe have contributed over the years is reflected in the chapters and in several cases that can be found at the end of each major section. The authors have focused on material that is timely and up-to-date, and relevant to the global context
Antecedents of verbal rumination in organizations
No full textOrganizations are riddled with complex interpersonal relationships in which many types of communication strategies are employed. Verbal rumination is one such communicative pattern, often used by organizational members as an attempt to talk through an ongoing problem or issue. Though verbal rumination has been a popular topic among interpersonal communication scholars, most organizational communication research has focused on the prevalence and ensuing harms of co-rumination in organizations, a distinctively different form of dyadic communication. The present study sought to examine what, if any, organizational, relational, and individual factors might encourage or inhibit verbal rumination in workplace settings. Results indicated that the prevalence of verbal rumination among coworkers is strongly influenced by relational factors such as perceived level of social support from coworkers and quality of exchanges in the workplace. Analysis of individual factors revealed that stress level and demographic differences proved influential on these behaviors as well

No full textDer Fotograf, Schriftsteller und Blogger Johny Pitts macht sich in seinem Buch Afropean. Notes from Black Europe auf die Suche nach Afroeuropäern. Seine Reise führt ihn als Backpacker durch Europa in Städte wie Paris, Lissabon und Stockholm, in denen er Menschen begegnet, die afrikanisch und europäisch zugleich sind. Pitts Reisebericht enthält neben zahlreichen Schilderungen von Begegnungen und Beobachtungen auch Schwarz-Weiß-Fotografien, die den Alltag von Afroeuropäerinnen und Afroeuropäern zeigen. Der Autor macht afroeuropäische Identitäten durch das Zusammenspiel von Bericht und visuellen Eindrücken nicht nur sichtbar, sondern zeigt ihre Vielfalt und Dynamik als Teil von Europa. Außerdem setzt er Impulse für zukünftige Forschung mit Fokus auf grenzüberschreitende und transnationale Identitäten, die ein Teil von Europa sind und dieses mitgestalten.In his book Afropean: Notes from Black Europe, the photographer, writer, and blogger Johny Pitts sets out in search of Afropeans. His journey takes him as a backpacker through Europe to cities such as Paris, Lisbon, and Stockholm, where he meets people who are African and European at the same time. Pitts’ travelogue contains numerous descriptions of encounters and observations as well as black-and-white photographs showing the everyday life of Afropeans. The author not only makes Afropean identities visible through the interplay of report and visual impressions, but also shows their diversity and dynamics as part of Europe. In addition, he provides impulses for future research with a focus on cross-border and transnational identities that are part of and shape Europe
A Temperature stabilised CMOS VCO based on amplitude control
No full textDissertation (MEng)--University of Pretoria, 2013.Speed, power and reliability of analogue integrated circuits (IC) exhibit temperature dependency through the modulation of one or several of the following variables: band gap energy of the semiconductor, mobility, carrier diffusion, current density, threshold voltage, interconnect resistance, and variability in passive components. Some of the adverse effects of temperature variations are observed in current and voltage reference circuits, and frequency drift in oscillators. Thermal instability of a voltage-controlled oscillator (VCO) is a critical design factor for radio frequency ICs, such as transceiver circuits in communication networks, data link protocols, medical wireless sensor networks and microelectromechanical resonators. For example, frequency drift in a transceiver system results in severe inter-symbol interference in a digital communications system. Minimum transconductance required to sustain oscillation is specified by Barkhausen’s stability criterion. However it is common practice to design oscillators with much more transconductance enabling self-startup. As temperature is increased, several of the variables mentioned induce additional transconductance to the oscillator. This in turn translates to a negative frequency drift.
Conventional approaches in temperature compensation involve temperature-insensitive biasing proportional-to-absolute temperature, modifying the control voltage terminal of the VCO using an appropriately generated voltage. Improved frequency stability is reported when compensation voltage closely follows the frequency drift profile of the VCO. However, several published articles link the close association between oscillation amplitude and oscillation frequency. To the knowledge of this author, few published journal articles have focused on amplitude control techniques to reduce frequency drift. This dissertation focuses on reducing the frequency drift resulting from temperature variations based on amplitude control. A corresponding hypothesis is formulated, where the research outcome proposes improved frequency stability in response to temperature variations.
In order to validate this principle, a temperature compensated VCO is designed in schematic and in layout, verified using a simulation program with integrated circuit emphasis tool using the corresponding process design kit provided by the foundry, and prototyped using standard complementary metal oxide semiconductor technology. Periodic steady state (PSS) analysis is performed using the open loop VCO with temperature as the parametric variable in five equal intervals from 0 – 125 °C. A consistent negative frequency shift is observed in every temperature interval (≈ 11 MHz), with an overall frequency drift of 57 MHz. However similar PSS analysis performed using a VCO in the temperature stabilised loop demonstrates a reduced negative frequency drift of 3.8 MHz in the first temperature interval. During the remaining temperature intervals the closed loop action of the amplitude control loop overcompensates for the negative frequency drift, resulting in an overall frequency spread of 4.8 MHz. The negative frequency drift in the first temperature interval of 0 to 25 °C is due to the fact that amplitude control is not fully effective, as the oscillation amplitude is still building up. Using the temperature stabilised loop, the overall frequency stability has improved to 16 parts per million (ppm)/°C from an uncompensated value of 189 ppm/°C.
The results obtained are critically evaluated and conclusions are drawn. Temperature stabilised VCOs are applicable in applications or technologies such as high speed-universal serial bus, serial advanced technology attachment where frequency stability requirements are less stringent. The implications of this study for the existing body of knowledge are that better temperature compensation can be obtained if any of the conventional compensation schemes is preceded by amplitude control.Electrical, Electronic and Computer Engineeringunrestricte

Konflik dan rekonsiliasi antarjemaat: Sebuah analisis teologis
No full textConflict and reconciliation are a reality in the life of congregations. Generally, conflict emerges in the life of the congregation because of non-theological reasons. Principally, congregations involved in a conflict have the responsibility to overcome the conflict. So do the Elpaputih and Samasuru, two congregations in the Protestant Church in the Moluccas involved in a conflict. This research aims to discover the potential reconciliation between these congregations. Through interviews and focus group discussions, the researcher discover that forgiveness is an essential bridge to reconciliation. At the end of the research, the author emphazise that reconciliation is a must because it is a church calling. For this case, the land as the source of the conflict must be a place for reconciliation when perceived as belonging to God and God??"s gift. AbstrakKonflik dan rekonsiliasi adalah kenyataan yang sangat sering dijumpai dalam kehidupan berjemaat. Umumnya, konflik yang terjadi dalam kehidupan jemaat didorong oleh faktor-faktor non-gerejawi. Pada hakikatnya, jemaat-jemaat yang berkonflik itu memiliki tanggung jawab untuk menyelesaikannya. Demikian juga dengan jemaat Samasuru dan jemaat Elpaputih; dua jemaat di Gereja Protestan Maluku yang berkonflik. Oleh karena itu, penelitian ini bertujuan untuk menemukan potensi-potensi di dalam jemaat-jemaat ini untuk membangun rekosiliasi di antara mereka. Dengan melakukan wawancara dan focus group discussion, penulis menemukan bahwa pengampunan merupakan jembatan menuju rekonsiliasi. Rekonsiliasi perlu dilakukan karena itu merupakan panggilan jemaat, di mana tanah sebagai sumber konflik dapat menjadi tempat rekonsiliasi, ketika tanah itu dilihat sebagai milik dan pemberian Tuhan.
