This paper demonstrates the existence of bi-directional relationships between interfirm collaboration and business sales. Entry and post-entry collaboration often contribute to superior performance, which in turn attracts more partners. At the same time, though, collaboration may impose constraints on growth opportunities. The relationships vary across types of collaborators and collaborations ...

in this study, the relative performance of mazandaran wood and paper company as a major supplier of paper products in iran was measured. network data envelopment analysis (dea) models with parallel structure were used to evaluate and measure its performance. gams software version 23.4 was used for data analysis. results indicated that this company in all studied years had good performances base...

Th rough their multiple roles in tourism, residents of destination communities interact with tourists at destinations. Th e consequences of these host-guest interactions are bi-directional. Much research has been done on impacts of host-guest interactions on the local community. On the other hand, few studies have evaluated how tourists' on-site behaviour and experiences are aff ected by such i...

Social computing refers to supporting social interaction and socialization by the use of IT systems [1; 2]. Within that context, the term “social software” is used for tools or services that “support, extend or derive added value from human social behavior” [3]. While both terms “social computing” and “social software” have only become relatively popular within the last five years, the core ide...

In this paper, the effect of renewable energy resources (RERs), demand response (DR) programs and electric vehicles (EVs) is evaluated on the optimal operation of a smart distribution company (SDISCO) in the form of a new bi-level model. According to the existence of private electric vehicle parking lots (PLs) in the network, the aim of both levels is to maximize the profits of SDISCO and the P...

The researchers reviewed 1,523 consecutive breast MRI exams performed from Jan. 1, 2003, to June 30, 2005, to identify all lesions initially detected on MRI and assessed as BI-RADS 4 or 5 for which the patient underwent subsequent imaging-guided needle or excisional biopsy.

Thin films of binary Bi 0 -TeO and Bi 0 -V 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. The optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a PERKIN-ELMER uv/Vis spectrophotometer. It is found that the value of n=3/2 in the Davis-Mott equation is best fitted for the fundamental absorption edge f...
