Might it be morally wrong to procreate? David Benatar answers affirmatively in Better Never to Have Been, arguing that coming into existence is always a great harm. I counter this view in several ways. First, I argue against Benatar's asserted asymmetry between harm and benefit--which would support the claim that any amount of harm in a human life would make it not worth starting--while questio...

the research was carried out to study the effect of provenance variation on stem length, stem biomass, root biomass and survival ofcaucasian oak (quercus macranthera) seedlings. the seeds were collected from several seed sources grown in an altitude range of 1800-2000 m a.s.l in alborz mountain, both from the northern facing slope, kordkoy and chichal, and from the southern facing slope, roudba...

Provenance information about complex and distributed workflows is a key issue for data quality control and data reliability maintenance in reservoir management. Distributed and integrated environments where different workflows consume and transform data require a comprehensive provenance view. In this scenario provenance collection and integration presents significant challenges. In this paper,...

Provenance, from the French word „provenir‟ meaning "to come from", describes the lineage of an entity. Provenance is critical information in eScience to accurately interpret scientific results. Though information provenance has been recognized as a hard problem in computing science (British Computing Society, 2004), many fundamental research issues in provenance have yet to be addressed. A com...

Provenance of scientific data is a key piece of the metadata record for the data's ongoing discovery and reuse. Provenance collection systems capture provenance on the fly, however, the protocol between application and provenance tool may not be reliable. Consequently, the provenance record can be partial, partitioned, and simply inaccurate. We used a workflow emulator that models faults to con...

Provenance records the history of data. Careless use of provenance may violate the security policies of data. Moreover, the provenance itself may be sensitive information, necessitating restrictions on the use of both data and provenance to enforce security requirements. This paper proposes extensional semantic definitions for provenance security. The semantic definitions require that provenanc...

Provenance means origin. There are two types of Provenance namely Data Provenance and Workflow Provenance. Data Provenance refers to the process of recording and tracking the source or origin of data while workflow provenance means history of workflows and their data that were used while performing an operation to get required result. The results which are obtained while performing operations a...

Provenance is defined in some literature as a complete documentation of process that led to an object. Provenance has been utilized in some contexts, i.e. database systems, file systems and grid systems. Provenance can be represented by a directed acyclic graph (DAG). In this paper we show an access control method to the provenance information that is represented by a directed acyclic graph and...

Provenance, from the French word “provenir”, describes the lineage or history of a data entity. Provenance is critical information in the sensors domain to identify a sensor and analyze the observation data over time and geographical space. In this paper, we present a framework to model and query the provenance information associated with the sensor data exposed as part of the Web of Data using...
