Taking time to understand: articulating relationships between technologies and organizations

Dynamic relationships between technologies and organizations are investigated through research on digital visualization technologies and their use in the construction sector. Theoretical work highlights mutual adaptation between technologies and organizations but does not explain instances of sustained, sudden, or increasing maladaptation. By focusing on the technological field, I draw attention to hierarchical structuring around inter-dependent levels of technology; technological priorities of diverse groups; power asymmetries and disjunctures between contexts of development and use. For complex technologies, such as digital technologies, I argue these field-level features explain why organizations peripheral to the field may experience difficulty using emerging technology.

Relationships between running economy and mechanics in middle-distance runners

Running economy (RE), i.e. the oxygen consumption at a given submaximal speed, is an important determinant of endurance running performance. So far, investigators have widely attempted to individuate the factors affecting RE in competitive athletes, focusing mainly on the relationships between RE and running biomechanics. However, the current results are inconsistent and a clear mechanical profile of an economic runner has not been yet established. The present work aimed to better understand how the running technique influences RE in sub-elite middle-distance runners by investigating the biomechanical parameters acting on RE and the underlying mechanisms. Special emphasis was given to accounting for intra-individual variability in RE at different speeds and to assessing track running rather than treadmill running. In Study One, a factor analysis was used to reduce the 30 considered mechanical parameters to few global descriptors of the running mechanics. Then, a biomechanical comparison between economic and non economic runners and a multiple regression analysis (with RE as criterion variable and mechanical indices as independent variables) were performed. It was found that a better RE was associated to higher knee and ankle flexion in the support phase, and that the combination of seven individuated mechanical measures explains ∼72% of the variability in RE. In Study Two, a mathematical model predicting RE a priori from the rate of force production, originally developed and used in the field of comparative biology, was adapted and tested in competitive athletes. The model showed a very good fit (R2=0.86). In conclusion, the results of this dissertation suggest that the very complex interrelationships among the mechanical parameters affecting RE may be successfully dealt with through multivariate statistical analyses and the application of theoretical mathematical models. Thanks to these results, coaches are provided with useful tools to assess the biomechanical profile of their athletes. Thus, individual weaknesses in the running technique may be identified and removed, with the ultimate goal to improve RE.

Effect of nitrogen supply on leaf appearance, leaf growth, leaf nitrogen economy and photosynthetic capacity in maize (Zea mays L.)

Leaf area growth and nitrogen concentration per unit leaf area, N-a (g m(-2) N) are two options plants can use to adapt to nitrogen limitation. Previous work indicated that potato (Solanum tuberosum L.) adapts the size of leaves to maintain Na and photosynthetic capacity per unit leaf area. This paper reports on the effect of N limitation on leaf area production and photosynthetic capacity in maize, a C4 cereal. Maize was grown in two experiments in pots in glasshouses with three (0.84-6.0 g N pot(-1)) and five rates (0.5-6.0 g pot(-1)) of N. Leaf tip and ligule appearance were monitored and final individual leaf area was determined. Changes with leaf age in leaf area, leaf N content and light-saturated photosynthetic capacity, P a,, were measured on two leaves per plant in each experiment. The final area of the largest leaf and total plant leaf area differed by 16 and 29% from the lowest to highest N supply, but leaf appearance rate and the duration of leaf expansion were unaffected. The N concentration of expanding leaves (N-a or %N in dry matter) differed by at least a factor 2 from the lowest to highest N supply. A hyperbolic function described the relation between P-max and N-a. The results confirm the 'maize strategy': leaf N content, photosynthetic capacity, and ultimately radiation use efficiency is more sensitive to nitrogen limitation than are leaf area expansion and light interception. The generality of the findings is discussed and it is suggested that at canopy level species showing the 'potato strategy' can be recognized from little effect of nitrogen supply on radiation use efficiency, while the reverse is true for species showing the 'maize strategy' for adaptation to N limitation.

Relationship between work performance and personality traits in Hong Kong organizational settings

Four hundred and thirty-seven employees from four Hong Kong organizations completed the Traditional Chinese versions of the Fifteen Factor Personality Questionnaire Plus (15FQ+) and the Cross-Cultural Personality Assessment Inventory (CPAI-2) (indigenous scales) and provided objective and memory-based recent performance appraisal scores. A number of significant bivariate correlations were found between personality and performance scores. Hierarchical multiple regression analyses revealed that a number of the scales from the 15FQ+ contributed to significantly predicting four of the performance competency dimensions, but that the CPAI-2 indigenous scales contributed no incremental validity in performance prediction over and above the 15FQ+. Results are discussed in the light of previous research and a call made for continued research to further develop and increase the reliability of the Chinese instruments used in the study and to enable generalization of the findings with confidence.

Affect networks:a structural analysis of the relationship between work ties and job-related affect

The relationship between organizational networks and employees' affect was examined in 2 organizations. In Study 1, social network analysis of work ties and job-related affect for 259 employees showed that affect converged within work interaction groups. Similarity of affect between employees depended on the presence of work ties and structural equivalence. Affect was also related to the size and density of employees' work networks. Study 2 used a 10-week diary study of 31 employees to examine a merger of 2 organizational divisions and found that negative changes in employees' affect were related to having fewer cross-divisional ties and to experiencing greater reductions in network density. The findings suggest that affect permeates through and is shaped by organizational networks.

The impact of buddying on psychological capital, work engagement and turnover intentions:an empirical study of socialization in the professional services sector

This article reports on a study investigating the impact of new employees' satisfaction with buddying on work engagement and explores the role of psychological capital in mediating this relationship. The study took place within a professional services organization wherein data were collected from 78 graduate newcomers in receipt of buddying. Satisfaction with buddying was found to have a positive relationship to both work engagement and psychological capital. The satisfaction with the buddy/work engagement relationship was fully mediated by psychological capital, providing support for Saks & Gruman's (2011) socialization resources theory. The results underscore the valuable role buddying can play as part of organizational socialization from a positive organizational behavior perspective. The research contributes to the growing evidence that positively oriented human resource practices can develop personal resources of newcomers within organizations. Recommendations are made for how the organization can improve and build upon this resource, thus developing the psychological capital of newcomers. © 2012 Wiley Periodicals, Inc.

Family-supportive work environment and employee work behaviors:an investigation of mediating mechanisms

This study examined psychological mechanisms that underpin the relationships between perceived organizational family support (POFS) and a family-supportive supervisor (FSS) on employee work behaviors. Based on data from employed parents and their supervisors (N = 230) in 12 South Korean organizations, structural equation modeling results revealed three salient findings: (1) POFS and FSS are indirectly related to contextual performance through control over work time, (2) FSS is indirectly related to both contextual performance and work withdrawal through organization-based self-esteem (OBSE), and (3) control over work time is indirectly related to the two work outcomes through OBSE. The authors interpret these findings as indicating support for the focus on informal workplace family support and the need for research to examine the psychological resources they engender if we are to understand why these forms of support have their demonstrated outcomes. © The Author(s) 2012.

The Worsening of the employment and work conditions and its relationship to the self-perceived health in European working population. Relevance and effects of the latest socioeconomic crisis

The recent crisis of the capitalistic economic system has altered the working conditions and occupations in the European Union. The recession situation has accelerated trends and has brought transformations that have been observed before. Changes have not looked the same way in all the countries of the Union. The social occupation norms, labour relations models and the type of global welfare provision can help underline some of these inequalities. Poor working conditions can expose workers to situations of great risk. This is one of the basic assumptions of the theoretical models and analytical studies of the approach to the psychosocial work environment. Changes in working conditions of the population seems to be important to explain in the worst health states. To observe these features in the current period of economic recession it has made a comparative study of trend through the possibilities of the European Working Conditions Survey in the 2005 and 2010 editions. It has also set different multivariate logistic regression models to explore potential partnerships with the worst conditions of employment and work. It seems that the economic crisis has intensified changes in working conditions and highlighted the effects of those conditions on the poor health of the working population. This conclusion can’t be extended for all EU countries; some differences were observed in terms of global welfare models.

Career development and personal functioning differences between work-bound and non-work bound students

We surveyed 506 Australian high school students on career development (exploration, planning, job-knowledge, decision-making, indecision), personal functioning (well-being, self-esteem, life satisfaction, school satisfaction) and control variables (parents’ education, school achievement), and tested differences among work-bound, college-bound and university-bound students. The work-bound students had the poorest career development and personal functioning, the university-bound students the highest, with the college-bound students falling in-between the other two groups. Work-bound students did poorest, even after controlling for parental education and school achievement. The results suggest a relationship between career development and personal functioning in high school students.

Four years after graduation : occupational therapists' work destinations and perceptions of preparedness for practice

Objective: The present study sought to identify the work destinations of graduates and ascertain their perceived preparedness for practice from a regional occupational therapy program, which had been specifically developed to support the health requirements of northern Australians by having an emphasis on rural practice. ---------- Design: Self-report questionnaires and semistructured in-depth telephone interviews. ---------- Participants: Graduates (n = 15) from the first cohort of occupational therapists from James Cook University, Queensland. ---------- Main outcome measure: The study enabled comparisons to be made between rural and urban based occupational therapists, while the semistructured interviews provided a deeper understanding of participants' experiences regarding their preparation for practice. ---------- Results: Demographic differences were noted between occupational therapists working in rural and urban settings. Rural therapists were predominantly younger and had worked in slightly more positions than their urban counterparts. The study also offered some insights into the value that therapists placed on the subjects taught during their undergraduate occupational therapy training, and had highlighted the differences in perceptions between therapists with rural experience and those with urban experience regarding the subjects that best prepared them for practice. Generally, rural therapists reported that all subjects included in the curriculum had equipped them well for practice. ---------- Conclusions: Findings suggest the need to undertake further research to determine the actual nature of rural practice, the personal characteristics of rural graduates and the experiences of students while on rural clinical placements.
