Despite considerable research investigating the role of influence tactics on work-related outcomes in organizations, consensus on the effectiveness of influence tactics has been elusive. Specifically, there is a lack of integration concerning the relationships between proactive influence tactics and their outcomes. We investigate the effectiveness of 11 influence tactics from a comprehensive perspective using meta-analytic techniques. In particular, the current study focuses on relationships between each of the 11 influence tactics (i.e., rational persuasion, exchange, inspirational appeal, legitimating, apprising, pressure, collaboration, ingratiation, consultation, personal appeals, and coalition) and task- and relations-oriented outcomes. In addition, we investigate the moderating effects of the direction of influence tactics, measurement of influence tactics, singular influence tactic (versus use of a combination of influence tactics), independence of data sources, and study setting involved in the study. Regardless of task- and relations-oriented outcomes, based on 49 independent samples (N = 8987), our results show positive relationships between outcomes and rational persuasion, inspirational appeal, apprising, collaboration, ingratiation, consultation, and a negative relationship between pressure and outcomes. Rational persuasion is the only tactic which held stable positive relationships with both categories of outcomes regardless of moderating factors. Implications and directions for future research in the area of influence tactics are discussed. 相似文献

Carbon dioxide (CO2) concentration variations in Rome in the period January 2009 to December 2010 was monitored. Five representative sites (T sites) in the city centre with different traffic levels and urbanistic characteristics, and four urban parks (P sites) of different sizes were selected. The regression analysis underlines the significant (p?≤?0.05) correlation between traffic levels and CO2 concentration. Considering the daytime CO2 concentration peak among T sites, Cerchi Street and Teatro Marcello Street, located in the city centre and closed by buildings, showed the highest traffic levels (85?±?3 and 63?±?2 cars min?1, respectively) and the highest CO2 concentration (512?±?11 and 488?±?8 ppm, respectively). With regards to the considered P sites, those extending over the largest surface areas (Villa Pamphilj Park and Villa Borghese Park, 180 and 80 ha, respectively) characterized by large tree coverage (81 ha and 60 ha, respectively) had a significant lower CO2 concentration (404?±?9 ppm, mean value) than those extending over a small surface area (Villa Torlonia Park and Villa Celimontana Park, 14 ha and 11 ha, respectively). More efforts should be made to further reduce CO2 concentration in the cities in order to ameliorate ecosystem services related to urban parks. 相似文献

The Maryland Court of Appeals in Grimes v. Kennedy Krieger Institute was sharply critical of the lead abatement study conducted by this Institute, an affiliate of Johns Hopkins University. Grimes ruled that investigators might, given the facts of the case, have a special relationship with subjects, thereby creating a duty of care that could, if breached, give rise to an action in negligence. This ruling has implications for pediatric research practices and long-standing disputes among informed people of good will about what pediatric studies should be permitted. 相似文献

Techniques used in variability assessment are subsequently used to draw conclusions regarding the “spread”/uniformity of data curves. Due to the limitations of these techniques, they are not adequate for circumstances where data manifest with multiple peaks. Examples of these manifestations (in three-dimensional space) include under-foot pressure distributions recorded for different types of footwear (Becerro-de-Bengoa-Vallejo et al., 2014; Cibulka et al., 1994; Davies et al., 2003), surface textures and interfaces designed to impact friction, and and and molecular surface structures such as viral epitopes (Torras and Garcia-Valls, 2004; Pacejka, 1997; Fustaffson, 1997). This article proposes a technique for generating a single variable – Λ that will quantify the uniformity of such surfaces. We define and validate this technique using several mathematical and graphical models. 相似文献

ABSTRACTThis paper explores the intersections of formal and informal care in the relationships that develop between elderly care receivers and their families and migrant domestic care workers and their families. The domestic migrant care literature has tended to focus on two main ‘hidden costs’ of this ‘care-chain’: the ‘care exploitation’ of paid carers by their employers and the ‘care drain’ impact on the family members left behind by the migrant. In this paper, we employ a care circulation framework to examine the process of becoming kin-like – or ‘kinning’, which remains relatively under-explored and warrants further research. An analysis of this process of kinning helps to highlight how the domestic space of care receiver homes are transformed – through the negotiation of relationships with migrant care workers – into transnational social fields that bring the diaspora worlds of the migrants into the everyday worlds of the locals. 相似文献

In this article, we perform Bayesian estimation of stochastic volatility models with heavy tail distributions using Metropolis adjusted Langevin (MALA) and Riemman manifold Langevin (MMALA) methods. We provide analytical expressions for the application of these methods, assess the performance of these methodologies in simulated data, and illustrate their use on two financial time series datasets. 相似文献

This paper examines the crisis of acute and chronic illness, death, and dying in transnational families. These are the stages in the family life-course when physical co-presence is required to deliver hands-on care and intimate emotional support for the sick family member. It is a time when distant kin feel they need ‘to be there’, including for their own sense of well-being. This period of ‘crisis’ (in the anthropological sense) makes visible all of the impediments to transnational family caregiving that often remain hidden during those periods when ‘routine’ forms of distant care are adequate. Of particular relevance are the macro-level factors generated by national borders and the policies that define them, including those that govern employment, travel, visa, health, and aged care provisions. It is in these family life phases of crisis that nation-state structures can work to constrain individual agency and rights, making compellingly evident the growing need for transnational structures and policy. At issue are the largely invisible (in a policy sense) but increasingly common micro-level responses of family and individuals that characterize ‘crisis distant care’, which are characterized by the urgent need to visit and to intensify use of ICTs. The paper examines the experiences of migrants living in Australia who are trying to care for acutely unwell family members abroad. 相似文献

The relationship between spending on education and equal opportunity has been a subject of debate for several decades. This study aims to shed light on this debate by examining correlations between the distribution of Blue Ribbon awards to Indiana middle and high schools and per pupil expenditure. Based on criteria that include curricula, instruction, school climate, leadership, community support, goal setting and attainment, success with all students, skill development, and character education, Blue Ribbon School awards are a recognition of outstanding achievement given by the federal government. Using total federal, state, and local expenditures as the basis for comparison, we found that the federal government did not select more wealthy schools than poor schools for the Indiana Blue Ribbon School awards. However, there was a large difference in the expenditures per pupil in the Indiana districts with Blue Ribbon schools vs. the 30 randomly selected Indiana districts without Blue Ribbon schools. Total local sources were significantly greater in Blue Ribbon school districts than in non-Blue Ribbon school districts. A discussion of items related to the power, prestige, and wealth of the award-winning schools is included. 相似文献
