Students’ achievement goals and beliefs of causes of success: Temporal relations and gender differences     

《Contemporary educational psychology》2021

According to the goal orientation model, students’ achievement goals and beliefs are interrelated. Within this framework, research and theory have so far assumed that achievement goals are associated with students’ beliefs of causes of success, the latter representing students’ subjective beliefs about the factors contributing to success at school. So far, this line of research has been restricted to a few cross-sectional studies. We examined the temporal relations between achievement goals (mastery, performance-approach, and performance-avoidance goals) and students’ beliefs of causes of success, the latter operationalized by asking the students to rate the subjective importance of diligence, effort, and ability for school success. Achievement goals and beliefs of causes of success were measured twice with a time lag of one school year with a sample of N = 2044 German secondary school students. Cross-lagged panel models were estimated to examine the temporal relations between achievement goals and beliefs of causes of success while controlling for students’ secondary school track, socio-economic status, and Grade Point Average. Former mastery goals were found to be positively related to later importance ratings of diligence for school success; former performance-approach goals were found to be positively related to later importance ratings of ability. Boys and girls were found to display similar relations among constructs but they showed differential mean levels on both the achievement goal constructs and the beliefs of causes of success. Implications for research on achievement goals and practice using intervention approaches are discussed.  相似文献

The balancing act of social enterprise: An IT emergence perspective     

《International Journal of Information Management》2021

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

Decoding digital transformational outsourcing: The role of service providers’ capabilities     

《International Journal of Information Management》2021

The business process outsourcing industry has got disrupted, first by the significant shift in value creation activities from the clients to the service providers, and second by pervasive digital penetration, resulting in the emergence of Digital Transformational Outsourcing (DTO). Service providers now play a more significant role, making their capabilities important. In the new context, service providers require a uniquely different set of dynamic capabilities to handle end-to-end business functions on behalf of their clients while delivering digital value propositions.We study 26 of the largest global business process outsourcing providers to conceptualise and identify six dynamic capabilities of service providers salient in the new context, i.e., consultative, orchestration, insights, network management, knowledge access, and standardisation. Interviews conducted with industry experts provided evidence in support of the identified dynamic capabilities. A novel firm capability dataset was created using secondary data, and using fuzzy-set Qualitative Comparative Analysis (fsQCA), we identify configurations for high and low performance and find them to vary by the firm's broad/narrow scope.  相似文献   

Genetic Polymorphism of Angiotensin II Type 1 Receptors and Their Effect on the Clinical Outcome of Captopril Treatment in Arab Iraqi Patients with Acute Coronary Syndrome (Mid Euphrates)     

Fadhaa A. Ghafil  Bassim I. Mohammad  Hussain S. Al-Janabi  Najah R. Hadi  Hayder A. Al-Aubaidy 《Indian journal of clinical biochemistry : IJCB》2021,36(1):81

Genetic variation in the angiotensin II type 1 receptor (AT1R) has an important effect on the outcome of acute coronary syndrome (ACS) initiated treatment with captopril. This study aims to investigate the impact of genetic polymorphism of AT1R (rs5186 and rs275651) on the ACS outcome in Iraqi patients treated with captopril. A total of 250 Iraqi individuals with ACS were included in this case—control study and they were divided into two study groups; Study group 1 included 125 participants who were prescribed captopril, 25 mg twice daily and study group 2 included 125 participants who received no captopril as part of their ACS treatment (control study). The AT1R gene (rs5186) CC genotype was found to be associated with ST-elevation myocardial infarction (STEMI) (Odd’s ratio (O.R) = 1.2, P = 0.7), while AC was associated with Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) (O.R = 1.2, P = 0.8). AC genotype is more prone to have Percutaneous coronary intervention (PCI) after ACS attack (O.R = 1.2, P = 0.6). CC genotype had a risk to get less improvement (O.R = 1.6, P = 0.5), so might require higher doses of captopril during acute coronary insult. The AT1R gene (rs275651) AA genotype was associated with UA (O.R = 1.3, P = 0.9). AA and AT genotypes were more prone to have PCI after ACS attack (O.R = 3.9 P = 0.2, O.R = 3.5, P = 0.3 respectively) and thus requiring higher doses of captopril. We conclude that the AT1R rs5186, rs275651 genetic polymorphisms might partially affect the clinical outcome of ACS patients treated with captopril and might have captopril resistance which requires higher doses.  相似文献

Magnetic-inertial measurement units (MIMUs) are becoming more prevalent in sports biomechanics and may be a viable tool to evaluate kinematic parameters. This study examined the accuracy of a MIMU to estimate orientation angles under static conditions and dynamically from a squash racket during a forehand drive shot. A MIMU was mounted onto a goniometer and moved through 0–90°, with static data collected at 10° increments during 10 repetitions of all three axes. Typical error analyses showed the MIMU to be very reliable (TE ≤ 0.03°). MIMU accuracy was determined via intraclass correlation coefficients (ICC) (r > 0.999, p < 0.001). An ordinary least products regression showed no proportional bias and minimal fixed bias for all axes. Dynamic accuracy was assessed by comparing MIMU and optical motion capture data of squash racket swing kinematics. A MIMU was fixed onto a racket and 10 participants each hit 10 forehand shots. Mean orientation angle error at ball impact was <0.50° and ICC showed very high correlations (r ≥ 0.988, p < 0.001) for all orientations. Swing phase root mean squared errors were ≤2.20°. These results indicate that a MIMU could be used to accurately and reliably estimate selected racket swing kinematics.  相似文献   

Engaging mothers with substance use issues and their children in early intervention: Understanding use of service and outcomes     

《Child abuse & neglect》2018

Mothers who use substances need integrated, multi-sectoral intervention services to support substance use discontinuation. We explored mothers’ service use at Breaking the Cycle, an early intervention and prevention program for pregnant and parenting women and their young children in Toronto, Canada. We conducted retrospective analyses of families’ service records and client charts (N = 160). Aims were to 1) describe women’s use of service, 2) examine how early engagement of pregnant women related to postnatal service use, and 3) examine the circumstances in which women ended their service relationship with Breaking the Cycle. Specifically, we examined circumstances at service ending relating to women’s service goals; custody status with children; and global substance-use, parent-child relationship, and child development outcomes. We found that these vulnerable women were actively engaged in many services and for a long duration, early engagement was associated with greater service use, and greater service use was associated with more positive circumstances upon ending service. Results provide support for a relational approach to service that promotes not only the relationship between mother and child, and mother and service provider, but also highlights relationships among staff, between staff and management, and between community partners as integral to effective service delivery. Integrating positive relationships at all levels is critical to support vulnerable families with complex needs.  相似文献
