AbstractE-marketplace platforms focus on attracting and retaining sellers to secure the platform’s long-term viability and success. Although sellers’ behavioral intentions have been linked to control modes deployed on e-marketplace platforms, little is known about how and why perceptions of input control and clan control affect sellers’ crucial behavioral outcomes. Drawing on IS control literature, we conducted two online surveys with sellers on Amazon (n = 286) and Etsy (n = 185). Our results revealed that perceived input control had a negative effect on sellers’ perceived usefulness, satisfaction, and continuance intentions, whereas positive effects were observed with perceived clan control. In addition, we find that intrinsic motivation mediates the observed direct effects. Our study contributes to the literature by introducing control modes in the context of e-marketplace platforms and examining the effects of input control and clan control on sellers’ beliefs, attitudes, and behavioral intentions. Furthermore, our study has important practical implications for platform providers in how to apply different control mechanisms and increase complementors’ willingness to keep contributing to e-marketplace platforms, thereby nurturing platform health and sustainability.

This paper examines foundings of human services organizations after natural disasters such as floods, earthquakes, wildfires, hurricanes, and tsunamis and explains why only some communities bounce back by founding appropriate collective-goods organizations. Using natural disasters in California counties from 1990 to 2010 as shocks that exogenously impose a need for collective goods over and above the level endogenous to the community, this paper shows that a geographic community’s local organizing capacity rests on the richness of its repertoire of voluntary organizing models as reflected in the diversity of its voluntary associations. Such diversity is even more critical when the type of natural disaster is more unexpected or complex (e.g., both a wildfire and an earthquake) in an area, and the organizational challenges posed are thus more novel for the community. Associational diversity has positive effects on both the numbers and aggregate size of foundings of local (non-branch, secular) human services organizations, and the effects are generalizable to other endogenous demand conditions such as poverty. Results also show how different kinds of variety can have opposing effects on organizing capacity after a disaster, with associational diversity having a positive effect, political diversity having a negative effect, and racial diversity having no significant effect, net of other factors. The paper concludes with a call for treating community resilience as a matter of enhancing local organizing capacity over centralized planning efforts when the environment is rapidly changing.

PurposeThe purpose of the study is to investigate the effects of interactivity and vividness on perceived usefulness and perceived enjoyment and their consequent impacts on consumer behavioral responses in a retail furniture VR store context. Considering the lack of VR empirical research, the indirect effect of interactivity and vividness on perceived usefulness and perceived enjoyment through telepresence and the moderating effect of consumer previous experience with VR are also included.Design/methodology/approachA commercial IKEA VR store was chosen for the study. Head-mounted display (HMD) VR headsets were employed for the VR shopping experience. The study was conducted at a laboratory at a large university in the southeastern United States. A total of 146 college students participated in the study.FindingsVividness had significant positive effects on perceived usefulness and perceived enjoyment, which in turn influenced attitude towards VR and behavioral intentions. Interactivity did not have positive impacts on perceived usefulness and perceived enjoyment. However, it indirectly affected perceived usefulness and perceived enjoyment through telepresence. The findings also proved the moderating effect of consumer previous VR experience between interactivity and perceived usefulness and between interactivity and perceived enjoyment. The relationship between attitude and behavioral intentions was also positive.Originality/valueNotwithstanding the benefits of VR in relation to its utilitarian, hedonic, and behavioral values, little is known about consumers' responses towards the usage of VR as a shopping tool. The present study can be considered as a starting point in understanding the usefulness of VR from consumer and managerial perspectives. The findings of VR indicated in the study will help practitioners understand the urgency of adopting VR in a retail setting.

Mechanical site preparation is commonly used to increase survival and early growth of newly planted seedlings. Ideally, any early positive effects of site preparation should persist for a long time, but concerns have been raised as to whether intensive site preparation might have a negative effect on the long-term productivity of a stand. The present study was therefore designed to investigate the long-term effects of different site-preparation methods on productivity and determine any possible interactions with tree species and site fertility. In the 1980s, a randomized block experiment was established at sites throughout Sweden. Four site-preparation methods of various intensities were performed on different sites: (i) an untreated control, (ii) disc trenching, (iii) mounding, and (iv) ploughing. As a complementary treatment, slash was either retained or removed from some plots. Depending on soil moisture class, geographical position, and site index, Norway spruce (Picea abies (L.) Karst.), Scots pine (Pinus sylvestris L.), or lodgepole pine (Pinus contorta Douglas ex Loudon) were planted in pure stands. Growth variables such as height and diameter were measured during the first years after establishment. After about 30 years, these variables were remeasured at the level of individual trees. Overall, an increased production of the planted trees after site preparation was found. Neither intensive site preparation (such as ploughing) nor slash removal had any negative effect on the long-term productivity of these experimental stands.

Exploration Phase

For sellers, the efficacy of humor to create trusty relationships and achieve performance with buyers remains unknown. Specifically, the question of if – and when – sellers should use humor still deserves examination. To answer this question, this research builds on the four phases that characterize long-term relationships (exploration, buildup, maturity, and decline) to argue that humor might be inefficient when used in the exploration phase. Two studies conducted among buyers ( n = 322) then reveal that although constructive humor has overall positive effects on the performance of the sellers through a mediating effect of trust, this effect is not observed during the exploration phase. The other type of humor – offensive humor – has a negative effect regardless of the phase in which it is used. Taken together, these results first indicate that sellers may gain from using humor only if the relationship with their buyers is not at the exploration phase since this particular phase is the only one when a negative effect of humor on trust and subsequent performance is observed. Furthermore, these results indicate that offensive should be avoided in all the relationship phases.

The article shows that depending on the goals pursued by the federal government and the available interbudgetary tools a different design of infrastructure mortgage is preferable. Three variants of such mortgage in Russia are proposed, each of which is better suited for certain types of projects and uses different forms of subsidies. According to our expert assessment the active use of infrastructure mortgage in Russia can increase the average annual GDP growth rate by 0.5 p. p. on the horizon of 5—7 years. In the long run the growth of infrastructure financing through the use of infrastructure mortgage could increase long-term economic growth by 0.9 p. p., which in 20—30 years can add 20—30% of GDP to the economy. However, the change in the structure of budget expenditures in the absence of an increase in the budget deficit and public debt will cause no direct impact on monetary policy. The increase in the deficit and the build-up of public debt will have a negative effect on inflation expectations, which will require monetary tightening for a longer time to stabilize them.

The depressing (negative) effect of oestradiol benzoate on the in vitro secretion of LH and FSH by the pituitary gland of the LRH-pretreated long-term ovariectomized rat changes into the augmentative (positive) effect after discontinuation of the LRH-pretreatment

Abstract. The effect of pretreatment in vivo with oestradiol benzoate on in vitro secretion of LH and FSH was studied in long-term ovariectomized (OVX) rats both at the end of a 5-day continuous in vivo pretreatment with LRH and 4-days after cessation of such LRH pretreatment. Rats were on day 0 sc implanted with osmotic minipumps which released LRH at the rate of 250 ng/h. Control rats were implanted with a piece of silicone elastomer with the dimensions of a minipump. On days 2 and 4 the rats were injected with either 3 μg EB or with oil. On day 5 part of the rats were decapitated and the in vitro autonomous (i.e. non-LRH-stimulated) and 'supra-maximally' LRHstimulated release of LH and FSH was studied using a perifusion system. From other rats the minipumps were removed on day 5 and perifusion was performed on day 9. On the 5th day of the in vivo LRH pretreatment the pituitary LH/FSH stores were partially depleted; the pituitaries of the EB-treated rats more so than those of the oil-injected rats. EB alone had no significant effect on the content of the pituitary LH- and FSH stores. On day 9, i.e. 4 days after removal of the minipumps, the pituitary LH and FSH contents had increased in both the oil- and the EB injected rats, but had not yet recovered to control values. In rats not subjected to the 5-days pretreatment with LRH EB had a positive effect on the supra-maximally LRH-stimulated secretion of LH and FSH as well as on the non-stimulated secretion of LH. EB had no effect on the non-stimulated secretion of FSH. After 5 days of in vivo pretreatment with LRH only, the in vitro non-stimulated and supra-maximally LRH-stimulated secretion of both LH and FSH were strongly impaired, the effect correlating well with the LRH-induced depletion of the pituitary LH/FSH stores. In such LRH-pretreated rats EB had on day 5 a negative effect on the (already depressed) LRH-stimulated secretion of LH (not on that of FSH). EB had no effect on the non-stimulated LH/FSH secretion. It could be demonstrated that the negative effect of the combined LRH/EB pretreatment was mainly due to the depressing effect of this treatment on the pituitary LH and FSH stores: the effect of oestradiol on the pituitary LRH-responsiveness (release as related to pituitary gonadotrophin content) remained positive. In LRH-pretreated rats, however, this positive effect of EB was smaller than in rats not pretreated with LRH. Four days after removal of the minipumps there was again a positive effect of EB on the LRH-stimulated secretion of LH and FSH as well as on the non-stimulated secretion of LH. The positive effect of EB on the pituitary LRH-responsiveness was as strong as in rats which had not been exposed to exogenous LRH. The non-stimulated secretion of FSH was again not affected by EB. The results demonstrate that the effect of EB on the oestrogen-sensitive components of gonadotrophin secretion consists of two components: an effect on the pituitary LRH-responsiveness proper, and an effect on the pituitary LH/FSH stores. The magnitude of the effect of EB on the LRH-responsiveness is LRH dependent: it is very weak (almost zero) in LRH-pretreated rats, but strong in rats not exposed to LRH as well as in rats of which the LRH-pretreatment was stopped 4 days previously. Similarly, the effect of EB on the pituitary LH and FSH stores is LRH-dependent: in the absence of LRH, EB has no influence on the contents of these stores, but EB can potentiate the depleting effect of LRH on the LH/FSH-stores. Also this effect disappear after cessation of the LRH-pretreatment.

Critical Challenge

Strategies to improve cognitive aging are highly needed. Among those, promotion of exercise and physical activity appears as one of the most attractive and beneficial intervention. Indeed, results from basic and clinical studies suggest that exercise and physical activity have positive effects on cognition in older persons without cognitive impairment, as well as in those with dementia. Despite inconsistent results, aerobic exercise appears to have the strongest potential to enhance cognition. However, even limited periods of walking (45 minutes, three times a week, over a 6-month period) have also been shown to enhance cognition, particularly executive functions. Changing long-term lifestyle habits in these older persons remains a critical challenge and attractive programs susceptible to gain adherence are needed to succeed in achieving improved cognitive aging.
