Employers are already hard-pressed to find qualified workers and look with interest to the growing population of technically trained deaf individuals as a new source of competent employees. Interest in hiring deaf computer professionals has also been accelerated by employers’ growing sense of social responsibility and their need to comply with government regulations concerning affirmative action in hiring and promoting handicapped individuals. This willingness to employ deaf professionals must be accompanied, however, by specific guidelines for the actual hiring and accommodation of such workers. This paper addresses the practical concerns of managers who wish to hire deaf professionals into their organization.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131949691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ideas for this sort of enhancement appear regularly in such publications as Sigplan Notices . As evidenced by the correspondence in that publication, there are many opinions on the quality of these proposals. However, little is known about the actual fate of enhancements that have been added to existing software systems and released to users. When a new feature is released with the best of intentions and the usual fanfare of documentation and instruction, its acceptance by programmers may have little to do with the sincerity of the request or the quality of the feature.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115205069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to this model a data base, DB, describes certain objects of the world having certain attributes, and the relationships among them. Thus, DB is characterized by a set of attributes, D , a set of domains associated with the attributes, and a set of dependencies, F , corresponding to the relationships among the attributes (all the terms and concepts not defined here are those of References 1 – 3 ). A data base is a collection of relations, R ={ R i }. Each relation R i is characterized by a set of attributes S i ={ D j | D j ∈ D } called its scheme , and consists of a set of tuples. Each tuple is a map from the attributes of the relation scheme to their domains that satisfies all the dependencies of F (we shall consider functional dependencies).","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"239 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124623700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Performance and economy of a fault-tolerant multiprocessor* 一种容错多处理机的性能和经济性*

The life-critical nature of these tasks and the profit-oriented attitude of airlines translate into some very challenging and sometimes contradictory computer requirements. For example, a candidate computer should be able to execute tasks on time, without significant delays, be extremely reliable, and yet be cost-effective. At a first glance these requirements seem to be in conflict with each other. After all, to meet the performance criteria some sort of parallelism such as multiprocessing capability would be in order. Second, to meet the reliability and safety requirements it would be necessary to use redundancy since no simplex computer could possibly meet the \"extremely improbable\" failure criterion of the Federal Aviation Administration. The result is a computer that could be very expensive. Yet it may still be cost-effective. The reason is that it is the balance between the benefits and costs that determines the cost-effectiveness of a product; cost alone is not a pertinent criterion. In this paper we intend to show that the FTMP architecture is a viable solution to the multi-faceted problems of safety, speed, and cost.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121246972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
