Gaining economic benefits from substantially lower labor costs has been reported as a major reason for offshoring labor-intensive information systems services to low-wage countries. However, if wage differences are so high, why is there such a high level of variation in the economic success between offshored IS projects? This study argues that offshore outsourcing involves a number of extra costs for the ^his paper was recommended for acceptance by Associate Guest Editor Erran Carmel. client organization that account for the economic failure of offshore projects. The objective is to disaggregate these extra costs into their constituent parts and to explain why they differ between offshored software projects. The focus is on software development and maintenance projects that are offshored to Indian vendors. A theoretical framework is developed a priori based on transaction cost economics (TCE) and the knowledge-based view of the firm, comple mented by factors that acknowledge the specific offshore context The framework is empirically explored using a multiple case study design including six offshored software projects in a large German financial service institution. The results of our analysis indicate that the client incurs post contractual extra costs for four types of activities: (1) re quirements specification and design, (2) knowledge transfer, (3) control, and (4) coordination. In projects that require a high level of client-specific knowledge about idiosyncratic business processes and software systems, these extra costs were found to be substantially higher than in projects where more general knowledge was needed. Notably, these costs most often arose independently from the threat of oppor tunistic behavior, challenging the predominant TCE logic of market failure. Rather, the client extra costs were parti cularly high in client-specific projects because the effort for managing the consequences of the knowledge asymmetries between client and vendor was particularly high in these projects. Prior experiences of the vendor with related client projects were found to reduce the level of extra costs but could not fully offset the increase in extra costs in highly client-specific projects. Moreover, cultural and geographic distance between client and vendor as well as personnel turnover were found to increase client extra costs. Slight evidence was found, however, that the cost-increasing impact of these factors was also leveraged in projects with a high level of required client-specific knowledge (moderator effect).

Cucumber mosaic virus (CMV) and tomato aspermy virus (TAV) belong to the Cucumovirus genus. They have a tripartite genome consisting of single-stranded RNAs, designated 1, 2, and 3. Previous studies have shown that viable pseudorecombinants could be created in vitro by reciprocal exchanges between CMV and TAV RNA 3, but exchanges of RNAs 1 and 2 were replication deficient. When we coinoculated CMV RNAs 2 and 3 along with TAV RNAs 1 and 2 onto Nicotiana benthamiana, a hybrid quadripartite virus appeared that consisted of TAV RNA 1, CMV RNAs 2 and 3, and a distinctive chimeric RNA originating from a recombination between CMV RNA 2 and the 3′-terminal 320 nucleotides of TAV RNA 2. This hybrid arose by means of segment reassortment and RNA recombination to produce an interspecific hybrid with the TAV helicase subunit and the CMV polymerase subunit. To our knowledge, this is the first report demonstrating the evolution of a new plant or animal virus strain containing an interspecific hybrid replicase complex.

While working in clinical and forensic psychology settings, a communication difficulty between the two professions became apparent. Forensic psychologists often appeared cold and callous from the clinical psychologist’s perspective, while clinical psychologists often appeared naïve or too client centered from the forensic psychologist’s perspective. I wondered if viewing each subfield of psychology as a culture could facilitate better communication through intercultural communication. Guided by Intercultural Communication in Contexts (Martin & Nakayama, 2010) in approaching intercultural communication between the two professions, I explored factors contributing to each profession’s cultural identities. Once this was established, I attempted to explore the different ways each culture could communicate more effectively. By recognizing and utilizing the strengths from each profession and understanding the possible pitfalls of one’s own, we may become competent in intercultural communication
The pragmatics of computer-mediated communication between South African and Mexican drug traffickers

South Africa and Mexico are ripe with drug trafficking. The gangs and syndicates running the drug businesses in these two countries collaborate occasionally. Communication between these international drug business partners takes place on social media. Their main language of communication is English, mixed with some limited use of Spanish and Afrikaans. The key purpose of the interactions between the South African and Mexican parties is the organisation of their business activities. This study aims at examining how the drug traffickers position each other and themselves regarding their common business interest and how their relationship evolves throughout their interactions. Moreover, it is of interest to look at how these people make use of different social media and their affordances. For this a qualitative analysis of the interaction between two drug traffickers (one South African and one Mexican) on Facebook, Threema and PlayStation 4 was performed. Computer-mediated communication between these two main informants was studied at various stages of their relationship. Results show that at first the interaction between the South African and Mexican drug traffickers consists of interpersonal negotiations of power. The high risk of the drug business and gang/syndicate membership paired with intercultural frictions causes the two interlocutors to be extremely cautious and at the same time to mark their position. As their relationship develops and they gain trust in each other a shift to interpersonal negotiations of solidarity takes place. In these discursive practices diverse linguistic strategies are employed for creating relational effects and for positioning the other and the self. The discursive activities of the interactants are also identity practices. Thus, the two drug traffickers construct identities through these social practices, positioning and their interpersonal relationship.
