Factors Affecting Change Over Time in Self-reported Health

AbstractVariation is described as two or more variants competing for finite resources. In this model, two outcomes are possible: language change or specialization. Specialization can be broken down further: specialization for different functions, and partial specialization – stable variation. In this paper, I analyze the differences between stable variation and language change using the two variables present in Ancient Egyptian possessive constructions. Observing four Egyptian possessive variants, split into two groups with two variants each – clitic possessor variants and full nominal possessor variants – for a total of 2251 tokens, I compare factors affecting variant choice in each possessive group. Results of distributional and multivariate analyses indicate that a) change over time occurs in clitic possession, while stable variation occurs with noun variants; and b) different kinds of factors govern the two sets: the continuous variable phrase complexity affects variant choice in nominal possession, but does not affect the clitic variants.

Purpose – The purpose of this paper is to address global sourcing organisational design through the following research questions: how do the roles performed by International Purchasing Offices (IPOs) change over time?; what are the resources/capabilities required by an IPO for an effective performance and how do they change over time?; and what are the contingent factors affecting such changes? Design/methodology/approach – The authors employed an exploratory multiple case study approach and analysed 14 Western IPOs located in China for a period between 2007 and 2012. The data were primarily collected through 34 direct, semi-structured interviews of IPO heads and sourcing managers or senior buyers. Findings – The authors identify and discuss the importance of ten roles played by IPOs and 12 required resources/capabilities. Furthermore, considering the changes that occurred to these IPOs over a five-year period (2007-2012), the authors observe three distinct evolutionary behaviours (i.e. “overall development”, “selective development”, and “stable configuration”) and highlight three contingent factors that jointly affect these behaviours (i.e. the architectural and technological complexity of the sourced items, annual volume sourced abroad, and experience in the foreign context). Originality/value – This paper contributes to the resource-based view of the firm in a global sourcing context by highlighting the resources/capabilities required by IPOs and discussing their characteristics. Furthermore, it proposes a typology of IPO micro-organisational evolutionary behaviours. Finally, it applies contingency theory and identifies three factors that might affect the evolutionary behaviours.

Abstract To characterize the stress regulation system, we use a reservoir to reflect how much stress an individual “holds” over time. Factors affecting what is contained in a stress reservoir are incoming stress (Input), accumulation/dissipation (Strdiss), and actions taken to discharge stress (e.g., Control). At the within person level, time-varying control predicts better Strdiss (β= -0.03±0.01, p <.001), even when controlling for between person differences (e.g., age, neuroticism) and between and within person impacts of Input. Thus, control reflects an important stress dissipation tool. Further analyses indicated a significant 2-way interaction between time-varying effects of Input and Control (β= 0.14±0.03, p <.0001) and Strdiss and Control (β= 0.60±0.18, p <.001) on self-reported health and a significant 3-way time-varying interaction of Input, Strdiss and Control on depression (β= -0.173±0.07, p <.012). Studies of this type move beyond the static assessments of risk and resilience to a more dynamic one.
