Taking away David’s sling*: environmental justice and land-use conflict in extractive resource development

Exploring cases of gas and coal extraction in Australia and the U.S.A., this paper considers instances in which legal and political frameworks have been used to prioritise development interests and minimise opportunities for community objection. Two case studies illustrate the role of law and the influence of politics on environmental conflict, conflict resolution, and participation in decision-making associated with resource extraction. A range of barriers to meaningful community participation in land-use decision-making are exposed by combining legal and non-legal concepts of equity and justice with ideologies of democracy and representation. These include asymmetry in information and resources available to parties; instances of misrecognition of weaker participants; and examples of malrecognition, where community attempts to engage democratic rights of public participation were thwarted by the strategic and deliberate actions of both industry and government. This paper illustrates the limits of current legal approaches to addressing land-use conflict and contributes to the developing scholarship of environmental justice as an analytic framework for addressing complex environmental and social justice issues.     

Underemployment,job attitudes,and turnover intentions

We surveyed three distinct samples of employees (Ns of 238, 102, and 981) in order to examine relations among various types of underemployment, job satisfaction, organizational commitment, and turnover intentions. Each dimension of underemployment is explored as a case of poor person‐job fit, and the fit literature is used to produce hypotheses about these relations. We also developed and validated the 9‐item Scale of Perceived Overqualification (SPOQ) to tap employee perceptions of surplus education, experience, and KSAs (knowledge, skills, and abilities). In general, perceptions of underemployment were associated with poor job satisfaction, particularly for facets with a direct causal relationship with the specific dimension of underemployment, such as overqualification and satisfaction with work. Perceived overqualification was also related to lower affective commitment, and higher intentions to turnover. For part‐time work, negative attitudes were only found when employees expressed a preference for full‐time work; a similar trend was not found for temporary workers, however. Implications for theory, research, and practice are delineated. Copyright © 2006 John Wiley & Sons, Ltd.     

What is the relationship between self-reported aberrant driving behaviors,mindfulness, and self-reported crashes and infringements?

Objectives: This study investigated the relationship between self-reported aberrant driving behaviors, mindfulness, and self-reported crashes and infringements.

Methods: Three hundred and eighteen participants (M = 46.0 years, SD = 13.7 years; female: 81.8%) completed an online survey that assessed aberrant driving behaviors, mindfulness (including regular mindfulness meditation [MM]), and self-reported crashes and infringements during the past 2 years. Structural equation modeling (SEM) was used to examine the relationship between self-reported aberrant driving behaviors and mindfulness simultaneously, as well as with participants' age and estimated kilometers driven over the past year.

Results: The results of the SEM showed that mindfulness was negatively related to each self-reported aberrant driving behavior, with the strongest relationships being between mindfulness and driving-related lapses (?0.58) and errors (?0.46). Participants who practice MM had significantly fewer crashes in the past 2 years and reported significantly fewer driving-related violations and lapses compared to participants who did not practice MM (crashes: 9.3% vs. 18.8%, P < .05; violations: M = 6.66 [SD = 3.44] vs. M = 7.68 [SD = 4.53], P < .05; errors: M = 5.17 [SD = 3.44] vs. M = 6.19 [SD = 4.12], P < .05).

Conclusions: More research is needed to understand whether MM results in more mindful and attentive drivers or whether individuals who practice MM may have other traits or behaviors that are linked to improved safety.     

Scientific Gear as a Vector for Non-Native Species at Deep-Sea Hydrothermal Vents

The fauna of deep-sea hydrothermal vents are among the most isolated and inaccessible biological communities on Earth. Most vent sites can only be visited by subsea vehicles, which can and do move freely among these communities. Researchers assume individuals of the regionally homogeneous vent fauna are killed by the change in hydrostatic pressure the animals experience when the subsea vehicles, which collected them, rise to the surface. After an Alvin dive, we found 38 apparently healthy individuals of a vent limpet in a sample from a hydrothermally inactive area. Prompted by our identification of these specimens as Lepetodrilus gordensis, a species restricted to vents 635 km to the south of our dive site, we tested whether they were from a novel population or were contaminants from the dive made 36 h earlier. The 16S gene sequences, morphology, sex ratio, bacterial colonies, and stable isotopes uniformly indicated the specimens came from the previous dive. We cleaned the sampler, but assumed pressure changes would kill any organisms we did not remove and that the faunas of the 2 areas were nearly identical and disease-free. Our failure to completely clean the gear on the subsea vehicle meant we could have introduced the species and any diseases it carried to a novel location. Our findings suggest that the nearly inaccessible biological communities at deep-sea vents may be vulnerable to anthropogenic alteration, despite their extreme physical conditions.     

Maternal effects on begging behaviour: an experimental demonstration of the effects of laying sequence, hatch order, nestling sex and brood size

Differential resource allocation by females across the laying sequence has been hypothesised as a mechanism through which females could either compensate nestlings that hatch last in asynchronous broods or promote brood reduction. In this study we artificially incubated eggs and cross-fostered offspring to manipulate nestlings’ position in the hatching order, to identify whether the competitive ability of nestlings is dependent on position in the laying sequence. In both control and experimentally reversed broods, first hatched chicks had a higher survival than last hatched siblings. Yet, nestlings that hatched from eggs laid in the second half of a clutch begged with a greater intensity than nestlings hatched from eggs laid in the first half of a clutch. In natural broods, the greater begging competitiveness of nestlings from later-laid eggs led to a moderation of sibling competition and these nestlings achieved the same body size and weight as nestlings from eggs laid in the first half of the clutch. The lack of a substantial difference in the size and condition of surviving nestlings in respect to laying order suggests that differential resource allocation across the egg-laying sequence partially compensates for hatching last in asynchronous broods and reduces the negative effects of the nestling size hierarchy. The effect of laying order, brood size and experimental treatment also differed for male and female nestlings. Our study highlights the need to be aware of the complex and subtle effects of nestling sex and laying sequence when investigating genetic and environmental influences on individual fitness.
