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.  相似文献

Humor orientation (HO) is an individual difference variable that influences production and delivery of humorous communication. Prior research indicates that people who score higher on HO enact humor more frequently and effectively, which in turn leads to more benefits and advantages in a variety of social and psychological outcomes. Research reported here extends this line of analysis with HO for its relationship to a broad gauge measure of benefit, satisfaction with life, extending HO into understudied domains. This study compared Bulgarian adults (n = 100) to several American samples. Primary findings were that Bulgarians were similar to American samples overall but scored consistently higher than Americans on satisfaction with life (SWL). HO and SWL are correlated (r = .27), a medium effect size.  相似文献

In sub-Saharan Africa, where there is limited financial and human capital, it is important to examine how social relationships may serve to promote or undermine human capital formation. However, little is known about the contributions of social relations to human capital development, especially in terms of academic achievement in Africa. This study examined how variations in key aspects of social relations among teachers; between teachers and students; between principals, teachers, parents and students affect achievement in mathematics among sixth graders in 70 schools in six districts in Kenya. We modeled mathematics achievement as a function of measures of social perception and support while adjusting for school-, classroom- and student level background characteristics. We found that net of teacher subject knowledge and background characteristics, teachers who display commitment to teaching by always correcting homework and keeping students engaged during math lessons had their students performing better. Teacher absenteeism and lack of interest in teaching were negatively associated with performance in math. Lack of parental involvement in the classroom also had negative effects on grades. At the school level, the level of engagement of the principal, measured by supervision of teachers and good interpersonal interactions with parents had positive effects on math achievement. Schools where parents provided material and financial support had better grades, while student delinquency and absenteeism negatively affected grades.  相似文献

从感觉训练、概念发展、行动技能、定向系统、求助技能、安全议题、小区资源与大众运输系统七个方面选取50项能力指标,对海峡两岸64名担任定向行走课程的教师进行问卷调查。调查结果显示:大多数被调查者认可这50项能力指标;定向行走教师对自己的课程与教学专业能力认可度多为中等,需要进一步作培训。同时发现,在定向行走课程与专业能力各向度的重要程度上,海峡两岸定向行走教师的认知有显著差异,各向度胜任程度的差异更加明显;而定向行走教师的年龄对定向行走课程与教学专业能力在重要程度和胜任程度上并没有显著差异;海峡两岸担任定向行走课程的教师,多数认为有培训的必要。建议将重要性在3.5以上的题目编制为《定向行走专业能力检核表》;将定向行走专业能力胜任程度在3.5以下的向度作为定向行走师资培训的参考。  相似文献

Multi-domain and longitudinal studies of student achievement routinely find moderate to strong correlations across achievement domains and even stronger within-domain correlations over time. The purpose of this study is to examine the sources of these patterns analysing student achievement in 5 domains across Years 3, 5 and 7. The analysis is of longitudinal population data of over 22,000 students and utilizes fixed-effects models to incorporate stable general and domain-specific latent factors. These latent factors correspond to a general cognitive-ability-like factor and specific aptitudes in particular, or types of, subject areas. The preferred model incorporates both general and domain-specific latent factors with stronger effects for the general factor, although the domain-specific factors are particularly strong for spelling and numeracy. When taking into account general and domain-specific latent factors, the effects of student’s socioeconomic status (SES) and school SES are trivial.  相似文献
