Opinions and characteristics of Portland Community College black students

The purpose of this study was to analyze and describe the opinions and characteristics of black students enrolled in Portland Community College. Data were obtained through a random sampling of two groups of subjects who were invited to participate in the study as follows: (1) Black subjects were 109 students who had completed their registration for the 1970 fall term, of whom 64 were males and 45 females. (2) White subjects were 50 students (33 males, 17 females) who were already attending classes at Portland Community College for the 1970 fall term. The data obtained from white subjects were used for comparative purposes to facilitate interpretation of that provided by black subjects. The subjects completed the Culture Fair Supplementary Form (1966) of the ACE Student Information Form (SIF) at Portland Community College during the 1970 fall term. The basic areas covered by the Student Information Form are as follows: (1) biographical and demographic information (2) educational and vocational aspirations (3) secondary school achievements (4) self-rating of traits and abilities (5) students' appraisal of college atmosphere (6) students' appraisal of guidance received, and (7) students' opinions of moral and sociological issues. To generate the significant differences between the response percentages of subjects, the following comparisons were made: (1) the response percentages of black males with white males (2) the response percentages of black females with white females. Statistical analyses were made by utilizing the t-test of differences between two percents, and simple Chi-square to test differences between the subjects' dichotomous responses and the subgroups. All differences were tested at the .05 level of significance. From the findings of this study, the following conclusions were drawn: 1. That black and white subjects differ, statistically, far less in their academic characteristics than in their psychological and sociological ones, as determined by self-report data. 2. That black students at Portland Community College, on the average, come from a significantly different and lower socio-economic background than do whites, as determined by self-report parental data. 3. That Portland Community College black students' opinions of themselves and general College environment are significantly different and less positive than are the opinions of their white peers. 4. That black students' negativistic attitude toward themselves and their present milieu is related to their lower socio-economic background and to their prior cultural experiences. 5. That black students' perception of the counselor and his counseling role determines whether they will make self-referrals for his professional service. 6. That despite the black students' negativistic orientation, they have certain attributes, such as athletic ability, drive to achieve, and desire for social or economic mobility, that can be utilized by educators in guiding them in actualizing their academic and non-academic potentials

Feeling our way: academia, emotions and a politics of care

This paper aims to better understand the role of emotions in academia, and their part in producing, and challenging, an increasingly normalized neoliberal academy. It unfolds from two narratives that foreground emotions in and across academic spaces and practices, to critically explore how knowledges and positions are constructed and circulated. It then moves to consider these issues through the lens of care as a political stance towards being and becoming academics in neoliberal times. Our aim is to contribute to the burgeoning literature on emotional geographies, explicitly bringing this work into conversation with resurgent debates surrounding an ethic of care, as part of a politic of critiquing individualism and managerialism in (and beyond) the academy. We consider the ways in which neoliberal university structures circulate particular affects, prompting emotions such as desire and anxiety, and the internalisation of competition and audit as embodied scholars. Our narratives exemplify how attendant emotions and affect can reverberate and be further reproduced through university cultures, and diffuse across personal and professional lives. We argue that emotions in academia matter, mutually co-producing everyday social relations and practices at and across all levels. We are interested in their political implications, and how neoliberal norms can be shifted through practices of caring-with

Can’t work or won’t work: quasi-experimental evidence on work search requirements for single parents

Increasing the labour market participation of single parents, whether to boost incomes or reduce welfare spending, is a major policy objective in a number of countries. This paper presents causal evidence on the impact of work search requirements on single parents’ transitions into work and onto other benefits. We use rich administrative data on all single parent welfare recipients, and apply a difference-in-differences approach that exploits the staggered roll-out of a reform in the UK that gradually decreased the age of the youngest child at which single parents lose the right to an unconditional cash benefit. Consistent with the predictions of a simple search model, the work search requirements have heterogeneous impacts, leading some single parents to move into work, but leading some (especially those with weak previous labour market attachments) to move onto disability benefits (with no search conditionalities) or non-claimant unemployment

Faulting and volcanism in the axial valley of the slow-spreading center of the Mariana back arc basin from Wadatsumi side-scan sonar images

The definitive version was published in Geochemistry Geophysics Geosystems 6 (2005): Q05006, doi:10.1029/2004GC000881.We analyzed in detail the geology of the median valley floor of the Mariana Basin slow-spreading ridge using sea surface geophysical data and a high-resolution deep-tow side-scan sonar survey over one spreading segment. Analysis of surface magnetic data indicates highly asymmetric accretion, with the half-spreading rate on the western side of the basin being two to three times larger than on the eastern side. Surface magnetic and reflectivity data together suggest that asymmetric spreading is accomplished through eastward ridge jumps of ∼10 km of amplitude. Deep-tow backscatter data indicate along-axis variations of the volcanic processes with the emplacement of smooth and hummocky flows at the segment center and end, respectively. This variation likely relates to changes in the effusion rate due to the deepening or even disappearance of the magma chamber toward the segment end. Concerning tectonic processes, we find a power law distribution of the fractures, with an exponent of 1.74. This suggests that within the inner valley floor, fracture growth prevails over fracture nucleation and coalescence and that fractures accommodate less than 8% of the strain. According to our calculation based on a ratio of 0.02 to 0.03 between the vertical displacement and the length of faults, the amount of tectonic strain accommodated in the inner valley floor would consistently be ∼1.1–3.4%. Data also show two distinct sets of fractures. One trend is parallel to the rift direction at the segment center (∼N160°E) and perpendicular to the plate separation direction. Another set trends ∼17° oblique to this direction (∼N175°E) and is located over the eastern part of the valley, in the vicinity of a major bounding fault also trending ∼N175°E, that is, obliquely to the direction of plate motion. We modeled the stress field near a major fault that is oblique to the regional stress field associated with plate separation using a three-dimensional boundary element approach. We found that the orientation of the predicted fissuring near the oblique fault is locally rotated by ∼15° due to a flexure of the bending plate close to this fault.The KR03-12 cruise was funded by both JAMSTEC and ORI.

Plos One, 11(3), 13. doi:10.1371/journal.pone.0151924The space-time pattern and environmental drivers (land cover, climate) of bovine anaplasmosis in the Midwestern state of Kansas was retrospectively evaluated using Bayesian hierarchical spatio-temporal models and publicly available, remotely-sensed environmental covariate information. Cases of bovine anaplasmosis positively diagnosed at Kansas State Veterinary Diagnostic Laboratory (n = 478) between years 2005-2013 were used to construct the models, which included random effects for space, time and space-time interaction effects with defined priors, and fixed-effect covariates selected a priori using an univariate screening procedure. The Bayesian posterior median and 95% credible intervals for the space-time interaction term in the best-fitting covariate model indicated a steady progression of bovine anaplasmosis over time and geographic area in the state. Posterior median estimates and 95% credible intervals derived for covariates in the final covariate model indicated land surface temperature (minimum), relative humidity and diurnal temperature range to be important risk factors for bovine anaplasmosis in the study. The model performance measured using the Area Under the Curve (AUC) value indicated a good performance for the covariate model (>0.7). The relevance of climatological factors for bovine anaplasmosis is discussed

Foundations of Translational Ecology

Ecologists who specialize in translational ecology (TE) seek to link ecological knowledge to decision making by integrating ecological science with the full complement of social dimensions that underlie today\u27s complex environmental issues. TE is motivated by a search for outcomes that directly serve the needs of natural resource managers and decision makers. This objective distinguishes it from both basic and applied ecological research and, as a practice, it deliberately extends research beyond theory or opportunistic applications. TE is uniquely positioned to address complex issues through interdisciplinary team approaches and integrated scientist–practitioner partnerships. The creativity and context-specific knowledge of resource managers, practitioners, and decision makers inform and enrich the scientific process and help shape use-driven, actionable science. Moreover, addressing research questions that arise from on-the-ground management issues – as opposed to the top-down or expert-oriented perspectives of traditional science – can foster the high levels of trust and commitment that are critical for long-term, sustained engagement between partners

Assessment of skill and portability in regional marine biogeochemical models: Role of multiple planktonic groups

Application of biogeochemical models to the study of marine ecosystems is pervasive, yet objective quantification of these models' performance is rare. Here, 12 lower trophic level models of varying complexity are objectively assessed in two distinct regions (equatorial Pacific and Arabian Sea). Each model was run within an identical one-dimensional physical framework. A consistent variational adjoint implementation assimilating chlorophyll-a, nitrate, export, and primary productivity was applied and the same metrics were used to assess model skill. Experiments were performed in which data were assimilated from each site individually and from both sites simultaneously. A cross-validation experiment was also conducted whereby data were assimilated from one site and the resulting optimal parameters were used to generate a simulation for the second site. When a single pelagic regime is considered, the simplest models fit the data as well as those with multiple phytoplankton functional groups. However, those with multiple phytoplankton functional groups produced lower misfits when the models are required to simulate both regimes using identical parameter values. The cross-validation experiments revealed that as long as only a few key biogeochemical parameters were optimized, the models with greater phytoplankton complexity were generally more portable. Furthermore, models with multiple zooplankton compartments did not necessarily outperform models with single zooplankton compartments, even when zooplankton biomass data are assimilated. Finally, even when different models produced similar least squares model-data misfits, they often did so via very different element flow pathways, highlighting the need for more comprehensive data sets that uniquely constrain these pathways

Effects of parameter indeterminacy in pelagic biogeochemical modules of Earth System Models on projections into a warming future: The scale of the problem

Numerical Earth System Models are generic tools used to extrapolate present climate conditions into a warming future and to explore geoengineering options. Most of the current-generation models feature a simple pelagic biogeochemical model component that is embedded into a three-dimensional ocean general circulation model. The dynamics of these biogeochemical model components is essentially controlled by so-called model parameters most of which are poorly known. Here we explore the feasibility to estimate these parameters in a full-fledged three-dimensional Earth System Model by minimizing the misfit to noisy observations. The focus is on parameter identifiability. Based on earlier studies, we illustrate problems in determining a unique estimate of those parameters that prescribe the limiting effect of nutrient- and light-depleted conditions on carbon assimilation by autotrophic phytoplankton. Our results showcase that for typical models and evaluation metrics no meaningful “best” unique parameter set exists. We find very different parameter sets which are, on the one hand, equally consistent with our (synthetic) historical observations while, on the other hand, they propose strikingly differing projections into a warming climate
