The balancing act of social enterprise: An IT emergence perspective

The significance of IT in the context of non-digital social enterprises (SEs) and its influence on the viability of such SEs have been less studied themes in information systems research. In the era of ubiquitous IT, SEs have increasing pressures to cope with the ever-dynamic technological domain while balancing their dual objectives. Data from a single revelatory case of Jaipur Rugs (JR), an SE situated in a developing country context (India), is used to fathom the peculiarities of the SE context with a focus on the sociomaterial phenomena of IT emergence. Using the three fundamental notions of sociomateriality theory (relationality, performativity, and practice) this interpretive study understands the mechanisms underlying the SE’s attempt to balance its financial and social sustainability objectives. Through the innovative use of IT, the SE establishes and maintains shared value, yielding stability and efficiency to the business (financial viability) while simultaneously ensuring scalability and effectiveness of their social impact. This study strengthens the perspective of IT as an emergent phenomenon situated in sociomaterial practices and fills a gap in organizational literature by examining such phenomenon in the rich context of SEs where achieving the balance between dual goals is increasingly dependent on non-human (IT) agents.

A color image segmentation method as used in the study of ancient monument decay

In the cultural heritage area, it is of fundamental importance to characterize and classify the conservation state of the materials constituting ancient monuments, in order to study and monitor their decay. Generally, the decay diagnosis is provided by “naked eye” analysis done by expert scientists “walking around” the artifact and recording the conservation state of each individual element they observe. In this paper, a color image segmentation approach, based on histogram threshold and edge detection techniques is presented, to extract degradation regions, characterized by holes or cavities, from color images of stone-materials. The goal is to provide an aid to the decay diagnosis by segmenting degraded regions from color images, computing quantitative data, such as the area and perimeter of the extracted zones, and processing qualitative information, such as various levels of depth detected into the same zones. Since color is a powerful tool in the distinction between objects, a segmentation technique based on color, instead of intensity only, has been used to provide a clearer discrimination between regions. The study case concerns the impressive remains of the Roman Theatre in the city of Aosta (Italy). In particular, we have processed and analyzed some color images of the theatre puddingstones, acquired by a camera.     

现代汉语N+V状中短语的句法功能与语义指向分析

现代汉语中,名词能够与动词组合构成N+V状中短语,其性质是动词性的,在句中能作谓语、定语、主语和宾语。N+V状中短语在作谓语时,其中的名词性状语N从语义指向上看,有时指向谓语动词V,有时指向结构中的其他名词性成分。
