Comparative evaluation of aesthetic, biological, and economic effectiveness of different lawn management programs

We evaluated aesthetic (lawn quality), biological (weeds and insect pests), and economic (management costs) effectiveness of a commercial (managed by a professional company), consumer (managed using consumer lawn care products following labeled instructions), integrated pest management (IPM) (pesticide applications based on monitoring and thresholds), organic (monitoring and need-based organic and natural product applications), and an untreated lawn care program. Percent weed cover was the lowest in the commercial followed by IPM, organic, and consumer programs. The commercial program had lower white grub density than all other programs, and the organic program had lower white grub density than the untreated program. The commercial program had the highest lawn quality while the untreated program had the lowest. The IPM and organic programs did not differ significantly in lawn quality, but both rated significantly higher than the consumer program. Annual costs were highest in the commercial ($382/0.05 ha) followed by the organic ($305/0.05 ha), IPM ($252/0.05 ha), and consumer program ($127/0.05 ha), respectively. We conclude that the commercial program produced the highest lawn quality, and weed and insect control, and was the most expensive. The IPM and organic programs were cheaper than the commercial program and produced slightly lower lawn quality. Although the consumer program was the cheapest, it produced the lowest weed control and lawn quality among treated lawns.     

Communication accommodation within global virtual team: The influence of cultural intelligence and the impact on interpersonal process effectiveness

The study builds on existing literature on global virtual team (GVT) and focuses on how individual members can achieve higher levels of interpersonal process effectiveness. Anchoring on the theory of intelligence, this study establishes and examines cultural intelligence (CQ) and how it can relate and influence a GVT member's interpersonal process effectiveness. Furthermore, this study extends the literature by drawing from communication accommodation theory in examining how communication accommodation plays an important role in the effective functioning of a GVT member. To test these assertions, data were collected from members of GVTs and their colleagues (n = 262 paired data) in a multinational information technology offshoring firm. Data were analyzed and the results revealed that a GVT member's CQ relates positively and significantly to effectiveness on both interpersonal processes of synergy and direction. Furthermore, results showed that communication accommodation of a GVT member is influenced by CQ which consequently impacts both effectiveness on interpersonal processes of synergy and direction. These results contribute to the growing literature on GVT and offer new practical insights on how to improve overall efficiency and work performance within GVT.     

Equity Dynamics in the Perceived Fairness of Infant Care

How is the perceived fairness of infant care affected by spouses' relative contributions to it and to other domains of their relationship? Longitudinal data on 178 couples expecting the birth of their first child were collected during a period spanning approximately the first year of the child's life. Overall, wives were more likely than husbands to see infant care as fair to the wife. Net of fathers' contributions to infant care, spouses were more likely to see infant care as fair to wives the more the father worked in paid labor and did housework and the more wives benefited in the sexual relationship. Fathers' contributions to infant care had a stronger effect on fairness when the child was a son. The findings are consistent with equity predictions in that fathers' compensatory contributions to other domains of marriage counterbalance an unequal workload in the arena of family work.     

Déréglementation du marché du travail versus gains de productivité? Analyse des données de vingt pays de l'OCDE (1960–2004)

L'estimation économétrique montre que la modération salariale et la diminution de la part du travail dans le revenu national réduisent la croissance de la productivité du travail. Ainsi, les réformes du marché du travail dictées par l'offre contribuent à réduire les gains de productivité, ce qui ne peut s'expliquer par l'afflux de main‐d'?uvre faiblement productive, comme l'avance l'OCDE. En outre, déréglementation, licenciements facilités et rotation accélérée de la main‐d'?uvre freinent l'apprentissage et l'accumulation des connaissances dans les entreprises, ainsi que le modèle «routinier» d'innovation, dit «Schumpeter II». Enfin, la pertinence des lois de Baumol et Verdoorn est remise en question.     

Spiritual needs of mothers with sick new born or premature infants—A cross sectional survey among German mothers

Background

Spirituality is part of the basic needs of all humans, yet often undervalued by health professionals. Less is known about the spiritual needs of mothers of preterm or sick new born children.

Role of Marital Quality in Explaining Depressive Symptoms After Marital Termination Among Older Adults

This study assesses whether prior marital quality moderates the impact of divorce or widowhood on subsequent depression. Poor marital quality may buffer depression associated with divorce/widowhood; conversely, the effect of divorce/widowhood on depression could be exacerbated by previous marital quality. Three waves from the National Survey of Families and Households based on respondents, ages 50 and older, (N?=?2,570) included eight marital quality measures. We find limited evidence suggesting higher marital quality elevates, while lower marital quality decreases, depression after divorce. No moderating effects were found for widowhood. Additionally, health condition is more important than current marital status for elders’ well-being after divorce or widowhood. Heterogeneity in the context of the marriage before divorce should be considered when examining marital termination effects on elders’ depression.     

Photogrammetry procedures applied to anthropometry

This study aims to evaluate the reliability and establish procedures for the use of digital photogrammetry in anthropometric measurements of the human hand. The methodology included the construction of a platform to allow the placement of the hand always equivalent to a distance of the camera lens and to annul the effects of parallax. We developed a software to perform the measurements from the images and built up a subject of proof in a cast from a negative mold, this object was subjected to measurements with digital photogrammetry using the data collection platform in caliper and the Coordinate Measuring Machine (MMC). The results of the application of photogrammetry in the data collection segment hand, allow us to conclude that photogrammetry is an effective presenting precision coefficient below 0.940. Within normal and acceptable values, given the magnitude of the data used in anthropometry. It was concluded photogrammetry then be reliable, accurate and efficient for carrying out anthropometric surveys of population, and presents less difficulty to collect in-place.     

Doing the Scut Work of Infant Care: Does Religiousness Encourage Father Involvement?

Considerable debate exists regarding whether religiousness promotes or impedes greater father involvement in parenting. Our study addresses this issue using a Midwestern longitudinal dataset that tracks the transition to first parenthood for 169 married couples. We focus on performance of the "messier" tasks of infant care. We find little evidence that religiousness enhances father involvement in this domain. Biblically conservative couples exhibit a greater gender gap in childcare than others, with mothers more involved than fathers. The gender gap is also greater the more fathers work outside the home, the greater mothers' knowledge of infant development, and the more unadaptable the infant. Average daily childcare is lower the greater spouses' work hours, but higher with difficult pregnancies or fussy babies.     

Social and Psychological Barriers to Private Retirement Savings in Hong Kong

Using a phone survey conducted among Hong Kong workers, we examined the association of institutional, social, and psychological factors with engagement in both private retirement savings and the total amount of savings. Alarmingly, this study demonstrates that approximately 42% of Hong Kong workers do not save privately for their retirement. We found that age, education, number of children, support from spouse and friends, social regulation, perceived financial knowledge, and financial management capacity are associated with engagement in private retirement savings. Among those who saved, age, education, perceived financial knowledge, and financial management capacity are related to the amount of savings. Measures that could increase the social support for retirement savings as well as enhance their financial knowledge and management ability should be developed and implemented so that more workers engage in private retirement savings. A promising policy option for the Hong Kong government is to offer a tax incentive to promote additional savings for old-age income protection.
