Procurement Contracts

When outsourcing design tasks, firms want their suppliers to be both efficient and adaptive. Whereas efficiency is necessary to reap economic gains from outsourcing, adaptation is required to deal with interdependencies as the design evolves. Achieving both objectives simultaneously, however, is difficult because procurement contracts require a trade-off between providing incentives for efficiency and facilitating adaptation. In the presence of formal contracts that provide strong incentives for efficiency, ensuring adaptation thus requires effective relational contracts between the buyer and the supplier. But because the focus of prior research has been on dyadic buyer–supplier relationships, it is unclear how the efficiency–adaptation trade-off can be mitigated in the multitier supplier systems that are common in many industries. Addressing this gap, we argue that in hierarchical supplier systems, relational contracts between contractual partners become more important, but at the same time harder to establish, than in single-tier supplier systems. An in-depth case study of the adaptive frictions that arose in the Airbus A350 program allows us to illustrate this challenge of tiered outsourcing. Moreover, we show how Airbus came to resolve the frictions by leveraging skip-level ties—direct informal contacts to lower-level suppliers with which no contractual relationship existed, thus replacing the archetypal notion of a supplier hierarchy by a more complex relationship structure. We discuss the boundary conditions of our findings and suggest propositions for the emergence of skip-level ties in tiered outsourcing.

Procurement Contracts

The study objective was to examine the influence of staff competence on performance of procurement contracts management in public sector. The study employed a case study design as a mechanism of resource allocation. The study targeted a total of 142 employees of TIB Development Bank Ltd which is a public bank operating in Tanzania. Stratified sampling technique was employed to select 85 employees. Data were collected from the sample through interview and questionnaire and then were analyzed using both descriptive statistics and inferential statistics while factor analysis was used to test the suitability of the data for analysis. Findings from Multiple regression indicated that staff competence (β1 = 0.279, p < 0.05) had a positive and significant influence on the performance of procurement contracts management. Additionally, the correlation revealed that staff competence is likely to strongly improve procurement contracts management performance. It is also vital for the organization to provide training to the staff so as to allow them to develop new skills and knowledge on procurement contracts management in order to improve the performance of such contracts.

The 1960S

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
