We postulated that environmental concern encompasses a wide range of different issues, often lumping pollution with habitat loss (or land use) and ecological resources (fish and wildlife). In this paper, we compare perceptions about a range of environmental and ecological resource issues, and explore ethnic/racial differences. We surveyed 1513 residents of New Jersey about 'environmental concerns', using both general environmental questions (two questions: How serious are environmental problems in New Jersey? Are you concerned about the loss of open space?) and ecological resource questions (12 questions: e.g., how important is planting trees in your neighborhood, how concerned are you about loss of breeding and feeding habitat for fish and birds?) in New Jersey. Not all concerns were rated equally. For the ecological questions, there were no ethnic differences in concerns over preserving areas around water supplies, loss of places to hunt and fish, and loss of places for quiet walks and cycling, but there were for the other 9 ecological concerns. For eight of these nine concerns, Spanish-speaking Hispanics were more concerned than others (including English-speaking Hispanics). We divided the ecological resources into three categories: ecological services (clean water and safety), ecological resources (fish and wildlife), and recreational services. The strongest correlates of people's association with enlarging and enhancing recreational services were Spanish-speaking Hispanics, who are supportive of regulations and believe local government is not doing enough for environmental problems. People concerned about the loss of ecological resources and open space believe the federal government and the state are not doing enough for the environment, were non-Hispanic White, want continued environmental regulations, were longer-term residents, were high school graduates, and were older (45-54 years). People interested in ecological services were college-educated, non

Internalized stigma and disclosure concerns are key elements for the study of mental health in people living with HIV. Since no measures of these constructs were available for Spanish population, this study sought to develop such instruments, to analyze their reliability and validity and to provide a short version. A heterogeneous sample of 458 adults from different Spanish-speaking countries completed the HIV-Internalized Stigma Scale and the HIV-Disclosure Concerns Scale, along with the Hospital Anxiety and Depression Scale, Rosenberg's Self-esteem Scale and other socio-demographic variables. Reliability and correlation analyses, exploratory factor analyses, path analyses with latent variables, and ANOVAs were conducted to test the scales' psychometric properties. The scales showed good reliability in terms of internal consistency and temporal stability, as well as good sensitivity and factorial and criterion validity. The HIV-Internalized Stigma Scale and the HIV-Disclosure Concerns Scale are reliable and valid means to assess these variables in several contexts.

To document the types of language-assistance services available in pharmacies and the perceptions of pharmacists regarding the effectiveness of these services, and to measure the attitudes toward counseling Spanish-speaking patients and cultural sensitivity of pharmacists. Cross-sectional assessment. Metropolitan Atlanta, Ga. Registered Georgia pharmacists residing in metropolitan Atlanta. Mailed survey, with repeat mailing 2 weeks later. 38 survey items measuring demographic and practice-site characteristics, types of language-assistance services available with an assessment of the effectiveness of each measured on a nominal scale, and attitudinal items concerning counseling of Spanish-speaking patients and pharmacists' cultural sensitivity using a 5-point Likert-type response scale. Of 1,975 questionnaires mailed, 608 were returned, a 30.8% response rate. Nearly two thirds of the pharmacists had recently counseled a Spanish-speaking patient, but only one fourth of those respondents considered their interactions effective. Nearly all pharmacists, 88.0%, worked in pharmacies with language-assistance services. Of seven types of these services, a mean of 2.19 were available in pharmacies, and the majority of pharmacists (84.4% or more) identifying a service considered it to be effective. The pharmacists were neutral about counseling Spanish-speaking patients (mean = 2.94) and indifferent toward other cultures (mean = 3.28); however, they agreed they had a responsibility to counsel Spanish-speaking patients, and they believed that use of language-assistance services would constitute a reasonable effort to counsel these patients. Pharmacists have an opportunity to address barriers to communication with the Spanish-speaking population through use of language-assistance services and educational measures within the profession.

Adolescent suicide is a major public health issue, and early and accurate detection is of great concern. There are many reliable instruments for this purpose, such as the Columbia-Suicide severity rating scale (C-SSRS), but no validation exists for Spanish speaking Latin American adolescents. To assess psychometric properties and cut-off scores of the C-SSRS in Spanish speaking adolescents. Exploratory assessment with principal component analysis (PCA) and Varimax rotation, and confirmatory analysis (CFA) were performed on two groups with 782 and 834 participants respectively (N=1616). Mean age was 24.8 years. A Receiver operator analysis was applied to distinguish between control and suicide-risk subgroups adolescents. Promax rotation yielded two 10-items factors, for suicide ideation and behavior respectively. C-SSRS was positively correlated with other suicide risk scales, such as Beck Depression Inventory-II, Suicidal Behaviors Questionnaire-Revised, or PHQ-9. Confirmatory factor analysis yielded a two-factor solution as the best goodness of fit model. C-SSRS showed adequate ability to detect suicide risk group with positive predictive value of 68.3%. ROC analyses showed cutoff scores of ≥ 6 and ≥ 4 for suicide ideation and behavior scales respectively. This research offers data supporting psychometric validity and reliability of C-SSRS in nonclinical Spanish-speaking students. Added benefits are flexible scoring and management easiness. This questionnaire yields data on distinct aspects of suicidality, being more parsimonious than separate administration of a bunch of questionnaires.

The Advisory Committee on Immunization Practices recommends routine human papillomavirus (HPV) vaccination for female adolescents aged 11 to 12 years, yet vaccination rates remain low. We conducted a qualitative study to understand English- and Spanish-speaking parents' reasons for noninitiation or noncompletion of the HPV vaccine series for their daughters. Parents of female adolescents aged 12 to 15 years who had not initiated or not completed the HPV vaccine series were identified through administrative data in 2 large urban safety net health care systems in Colorado. Focus groups and in-depth interviews were conducted with English-speaking parents and in-depth interviews were conducted with Spanish-speaking parents. All data were recorded, transcribed, and analyzed for thematic content by experienced analysts using established qualitative content analysis techniques. Forty-one parents participated in the study. Thirty parents participated in individual interviews and 11 parents participated in 1 of 2 focus groups. The most common reasons for noninitiation and noncompletion among English-speaking parents included a low perceived risk of HPV infection, vaccine safety concerns, and distrust of government and/or medicine. In contrast, Spanish-speaking parents most often reported that providers had either not encouraged initiation of the HPV vaccine series or had not explained the necessity of completing the series. Some noninitiating parents, particularly Spanish-speaking ones, also cited concerns that vaccination would encourage sexual activity. The reasons for noninitiation and noncompletion of the HPV vaccine series differed substantially between English- and Spanish-speaking parents. To maximize uptake of HPV vaccine, varying approaches might be needed to effectively target specific populations. Copyright © 2017 Academic Pediatric Association. All rights reserved.

An increasing proportion of pediatric cancer patients in the United States are Latino and many have Spanish-speaking immigrant parents with limited English proficiency (LEP). Little is known about how language or undocumented immigration status impacts their care experience. A cross-sectional survey was administered to English (N = 310) and Spanish-speaking LEP (N = 56) caregivers of pediatric cancer patients. To assess differences in healthcare experiences between the language groups, t-tests and chi-square statistics were used. Multivariable logistic regression evaluated associations between primary language and knowledge of clinical trial status. Spanish-speaking caregivers were more likely to report higher rates of quitting or changing jobs as a direct result of their child's cancer, and their children were more likely to experience a delay in education. Although Spanish-speaking caregivers reported higher satisfaction with care, 32% reported feeling that their child would have received better care if English was their primary language. Spanish-speaking caregivers were more likely to incorrectly identify whether their child was on a clinical trial compared with English-speaking caregivers. The majority of Spanish-speaking caregivers reported at least one undocumented caregiver in the household and 11% of them avoided or delayed medical care for their child due to concerns over their undocumented immigration status. Language barriers and undocumented immigration status may negatively impact the quality of informed decision-making and the care experience for Spanish-speaking LEP caregivers of pediatric cancer patients. These families may benefit from culturally appropriate Spanish language resources to improve communication and open a dialogue regarding undocumented immigration status. © 2016 Wiley Periodicals, Inc.

The syntactic skills of Spanish-speaking children with Williams syndrome (WS) were assessed in different areas (phrase structure, recursion, and bound anaphora). Children were compared to typically-developing peers matched either in chronological age (CA-TD) or in verbal age (VA-TD). In all tasks children with WS performed significantly worse than CA-TD children, but similarly to VA-TD children. However, significant differences were observed in specific domains, particularly regarding sentences with cross-serial dependencies. At the same time, children with WS were less sensitive to syntactic constraints and exhibited a poorer knowledge of some functional words (specifically, of nonreflexive pronouns). A processing bottleneck or a computational constraint may account for this outcome. Copyright © 2016 Elsevier Inc. All rights reserved.
Full Text Available This work aimed at studying the relationship between personality from the Big Five Personality model and creativity through different techniques (i.e., a paper and pencil task, and scales and informants (i.e., the child and parents. We evaluated a sample of 359 Spanish-speaking school children of both genders, aged 9 to 13 years. Personality was assessed with the Argentine Questionnaire of children’s Personality (CAPI. Creativity was evaluated using the following instruments: The Torrance Test of Creative Thinking-Figural Form B; and the Creative Personality Scale (EPC. Pearson correlations and multiple linear regressions consistently showed that Neuroticism related negatively to creativity while competence has a positive relation. The results suggested that more creative children presented less vulnerability, irritability and psychological distress, eventually becoming more independent, competent and emotionally self-regulated in coping with environmental demands.

Williams syndrome (WS) is a genetic disorder associated with intellectual disability and characterised by displaying an atypical neuropsychological profile, with peaks and valleys, where language skills seem better preserved than non-verbal intelligence. This study researches the narrative competence of nine Spanish-speaking adults with WS. Oral narratives were elicited from a silent film, and narrative coherence was analysed as a function of sequential order of the events narrated at three structure levels, while narrative cohesion was assessed through the frequency of use and type of discourse markers. WS subjects were able to remember a significant proportion of the events from the film, but coherence of narratives, i.e., sequential order of events, was more impaired. Consistently with their linguistic abilities, cohesion of narratives was better preserved, as they used discourse markers to introduce a high proportion of events. Construction of mental models of the narratives may be constrained in WS by non-verbal cognitive abilities, but narrative competence is also determined by textual pragmatic abilities to organize discourse, which should be addressed by specific intervention in narrative competence.

Effective communication with primary care physicians is important yet incompletely understood for Spanish-speaking parents. We predicted lower satisfaction among Spanish-speaking compared to English-speaking Latino and non-Latino parents. Cross-sectional analysis at 2-month well visits within the Greenlight study at 4 pediatric resident clinics. Parents reported satisfaction with 14 physician communication items using the validated Communication Assessment Tool (CAT). High satisfaction was defined as "excellent" on each CAT item. Mean estimations compared satisfaction for communication items among Spanish- and English-speaking Latinos and non-Latinos. We used generalized linear regression modeling, adjusted for parent age, education, income, and clinic site. Among Spanish-speaking parents, we compared visits conducted in Spanish with and without an interpreter, and in English. Compared to English-speaking Latino (n = 127) and non-Latino parents (n = 432), fewer Spanish-speaking parents (n = 303) reported satisfaction with 14 communication items. No significant differences were found between English-speaking Latinos and non-Latinos. Greatest differences were found in the use of a greeting that made the parent comfortable (59.4% of Spanish-speaking Latinos endorsing "excellent" vs 77.5% English-speaking Latinos, P English-speaking Latinos, P < .01). After adjusting for parent age, education, income, and study site, Spanish-speaking Latinos were still less likely to report high satisfaction with these communication items. Satisfaction was not different among Spanish-speaking parents when the physician spoke Spanish versus used an interpreter. Satisfaction with physician communication was associated with language but not ethnicity. Spanish-speaking parents less frequently report satisfaction with communication, and innovative solutions to enhance communication quality are needed. Copyright © 2017 Academic Pediatric Association.

OBJECTIVE To assess Spanish-speaking patients' satisfaction with their clinical pharmacists' communication skills and demonstration of cultural sensitivity, while controlling for patients' sociodemographic, clinical, and communication factors, as well as pharmacist factors, and to identify clinical pharmacists' cultural factors that are important to Spanish-speaking patients. DESIGN Cross-sectional study. SETTING Central Texas during August 2011 to May 2012. PARTICIPANTS Spanish-speaking patients of federally qualified health centers (FQHCs). MAIN OUTCOME MEASURE(S) A Spanish-translated survey assessed Spanish-speaking patients' satisfaction with their clinical pharmacists' communication skills and demonstration of cultural sensitivity. RESULTS Spanish-speaking patients (N = 101) reported overall satisfaction with their clinical pharmacists' communication skills and cultural sensitivity. Patients also indicated that pharmacists' cultural rapport (e.g., ability to speak Spanish, respectfulness) was generally important to Spanish speakers. Multiple linear regression analyses showed that cultural rapport was significantly related to satisfaction with pharmacists' communication skills and demonstration of cultural sensitivity. CONCLUSION Overall, patients were satisfied with pharmacists' communication skills and cultural sensitivity. Patient satisfaction initiatives that include cultural rapport should be developed for pharmacists who provide care to Spanish-speaking patients with limited English proficiency.

There is a great need in the United States to develop presymbolic evaluation tools that are widely available and accurate for individuals that come from a bilingual and/or multicultural setting. The Communication Complexity Scale (CCS) is a measure that evaluates expressive presymbolic communication including gestures, vocalizations and eye gaze. Studying the effectiveness of this tool in a Spanish speaking environment was undertaken to determine the applicability of the CCS with Spanish speaking children. Methods & Procedures: In 2011-2012, researchers from the University of Kansas and Centro Ann Sullivan del Perú (CASP) investigated communication in a cohort of 71 young Spanish speaking children with developmental disabilities and a documented history of self-injurious, stereotyped and aggressive behaviors. Communication was assessed first by parental report with translated versions of the Communication and Symbolic Behavior Scales (CSBS), a well-known assessment of early communication, and then eleven months later with the CCS. We hypothesized that the CCS and the CSBS measures would be significantly correlated in this population of Spanish speaking children. The CSBS scores from time 1 with a mean participant age of 41 months were determined to have a strong positive relationship to the CCS scores obtained at time 2 with a mean participant age of 52 months. The CCS is strongly correlated to a widely accepted measure of early communication. These findings support the validity of the Spanish version of the CCS and demonstrate its usefulness for children from another culture and for children in a Spanish speaking environment.
A pandemic is a human medical problem but must be understood at multiple levels. Analysis of social and commercial forces is vital, and, more comprehensively, an ecological framework is necessary for an inclusive picture. Ecological health webworked with political and social determinants surrounds issues of human health. In this constellation of both natural and social factors, ethical concerns will arise at these multiple levels, from human health to the conservation and health of wild nature.

This article presents a tool for assessing the early numerical abilities of Spanish-speaking Mexican preschoolers. The Numerical Abilities Test, from the Evaluación Neuropsicológica Infantil-Preescolar (ENI-P), evaluates four core abilities of number development: magnitude comparison, counting, subitizing, and basic calculation. We evaluated 307 Spanish-speaking Mexican children aged 2 years 6 months to 4 years 11 months. Appropriate internal consistency and test-retest reliability were demonstrated. We also investigated the effect of age, children's school attendance, maternal education, and sex on children's numerical scores. The results showed that the four subtests captured development across ages. Critically, maternal education had an impact on children's performance in three out of the four subtests, but there was no effect associated with children's school attendance or sex. These results suggest that the Numerical Abilities Test is a reliable instrument for Spanish-speaking preschoolers. We discuss the implications of our outcomes for numerical development.

The purpose of our study was to evaluate barriers in communication and disease understanding among office staff and interpreters when communicating with Spanish-speaking women with pelvic floor disorders. We conducted a qualitative study to evaluate barriers to communication with Spanish-speaking women with pelvic floor disorders among office staff and interpreters. Sixteen office staff and interpreters were interviewed; interview questions focused on experiences with Spanish-speaking patients with pelvic floor disorders in the clinic setting. Interview transcripts were analyzed qualitatively using grounded theory methodology. Analysis of the interview transcripts revealed several barriers in communication as identified by office staff and interpreters. Three major classes were predominant: patient, interpreter, and system-related barriers. Patient-related barriers included a lack of understanding of anatomy and medical terminology and inhibited discussions due to embarrassment. Provider-related barriers included poor interpreter knowledge of pelvic floor vocabulary and the use of office staff without interpreting credentials. System-related barriers included poor access to information. From these preliminary themes, an emergent concept was revealed: it is highly likely that Spanish-speaking women with pelvic floor disorders have poor understanding of their condition owing to multiple obstacles in communication. There are many levels of barriers to communications with Latin women treated for pelvic floor disorders, arising from the patient, interpreter, and the system itself. These barriers contribute to a low level of understanding of their diagnosis, treatment options, and administered therapies.

Limited health literacy (HL) contributes to poor health outcomes and disparities, and direct measurement is often time-intensive. Self-reported HL questions have not been validated among Spanish-speaking and diverse English-speaking populations. To evaluate three self-reported questions: 1 "How confident are you filling out medical forms?"; 2 "How often do you have problems learning about your medical condition because of difficulty understanding written information?"; and 3 "How often do you have someone help you read hospital materials?" Answers were based on a 5-point Likert scale. This was a validation study nested within a trial of diabetes self-management support in the San Francisco Department of Public Health. English and Spanish-speaking adults with type 2 diabetes receiving primary care. Using the Test of Functional Health Literacy in Adults (s-TOFHLA) in English and Spanish as the reference, we classified HL as inadequate, marginal, or adequate. We calculated the C-index and test characteristics of the three questions and summative scale compared to the s-TOFHLA and assessed variations in performance by language, race/ethnicity, age, and education. Of 296 participants, 48% were Spanish-speaking; 9% were White, non-Hispanic; 47% had inadequate HL and 12% had marginal HL. Overall, 57% reported being confident with forms "somewhat" or less. The "confident with forms" question performed best for detecting inadequate (C-index = 0.82, (0.77-0.87)) and inadequate plus marginal HL (C index = 0.81, (0.76-0.86); pSpanish and English speakers with adequate HL and those with inadequate and/or inadequate plus marginal HL. The "confident with forms" question or the summative scale may be useful for estimating HL in clinical research involving Spanish-speaking and English-speaking, chronically-ill, diverse populations.

Background Many national surveys have found substantial differences in self-reported overall health (SROH) between Spanish-speaking Hispanics and other racial/ethnic groups. However, because cultural and language differences may create measurement bias, it is unclear whether observed differences in SROH reflect true differences in health. Objectives This study uses a cross-sectional survey to investigate psychometric properties of the SF-36v2 for subjects across four racial/ethnic and language groups. Multi-group latent variable modeling was used to test increasingly stringent criteria for measurement equivalence. Subjects Our sample (N = 1281) included 383 non-Hispanic whites, 368 non-Hispanic blacks, 206 Hispanics interviewed in English and 324 Hispanics interviewed in Spanish recruited from outpatient medical clinics in two large urban areas. Results We found weak factorial invariance across the four groups. However, there was no strong factorial invariance. The overall fit of the model was substantially worse (change in CFI > .02, RMSEA change > .003) after requiring equal intercepts across all groups. Further comparisons established that the equality constraints on the intercepts for Spanish-speaking Hispanics were responsible for the decrement to model fit. Conclusions Observed differences between SF-36v2 scores for Spanish speaking Hispanics are systematically biased relative to the other three groups. The lack of strong invariance suggests the need for caution when comparing SF-36v2 mean scores of Spanish-speaking Hispanics with those of other groups. However, measurement equivalence testing for this study supports correlational or multivariate latent variable analyses of SF-36v2 responses across all four subgroups, since these analyses require only weak factorial invariance.

Despite the growing literature on health care quality, few patient satisfaction studies have focused upon the public health setting; where many Hispanic patients receive care. The purpose of this study was to examine the differences in satisfaction between English and Spanish-speaking patients in a local health department clinical setting. We conducted a paper-based satisfaction survey of patients that visited any of the seven Jefferson County Department of Health primary care centers from March 19 to April 19, 2008. Using Chi-squared analyses we found 25% of the Spanish-speaking patients reported regularly having problems getting an appointment compared to 16.8% among English-speakers (p speaking patients controlling for center location, purpose of visit, and time spent waiting. Specifically, Spanish speaking patients were more likely to report problems getting an appointment and less likely to report having their medical problems resolved when leaving their visit as compared to those who spoke English. Findings presented herein may provide insight regarding the quality of care received, specifically regarding patient satisfaction in the public health setting. © 2011 National Association for Healthcare Quality.

The objective of this study was to compare perceptions and barriers between Spanish-speaking and English-speaking women in public and private hospitals being treated for pelvic organ prolapse (POP). Eight focus groups, 4 in English and 4 in Spanish, were conducted at 3 institutions with care in female pelvic medicine and reconstructive surgery. Standardized questions were asked regarding patients' emotions to when they initially noticed the POP, if they sought family support, and their response to the diagnosis and treatment. Transcripts were analyzed using grounded theory qualitative methods. Thirty-three women were Spanish-speaking and 25 were English-speaking. Spanish speakers were younger (P = 0.0469) and less likely to have a high school diploma (P speaking women had more concerns that the bulge or treatments could lead to cancer, were more resistant to treatment options, and were less likely to be offered surgery. Women in the private hospital desired more information, were less embarrassed, and were more likely to be offered surgery as first-line treatment. The concept emerged that patient care for POP varied based on socioeconomic status and language and suggested the presence of disparities in care for underserved women with POP. The discrepancies in care for Spanish-speaking women and women being treated at public hospitals suggest that there are disparities in care for POP treatment for underserved women. These differences may be secondary to profit-driven pressures from private hospitals or language barriers, low socioeconomic status, low health literacy, and barriers to health care.

There currently are few web-based resources written in Spanish providing oncology-specific information. This study examines utilization of Spanish-language oncology web-based resources and evaluates oncology-related Internet browsing practices of Spanish-speaking patients. OncoLink (http://www.oncolink.org) is the oldest and among the largest Internet-based cancer information resources. In September 2005, OncoLink pioneered OncoLink en español (OEE) (http://es.oncolink.org), a Spanish translation of OncoLink. Internet utilization data on these sites for 2006 to 2007 were compared. Visits to OncoLink rose from 4,440,843 in 2006 to 5,125,952 in 2007. OEE had 204,578 unique visitors and 240,442 visits in 2006, and 351,228 visitors and 412,153 visits in 2007. Although there was no time predilection for viewing OncoLink, less relative browsing on OEE was conducted during weekends and early morning hours. Although OncoLink readers searched for information on the most common cancers in the United States, OEE readers most often search for gastric, vaginal, osteosarcoma, leukemia, penile, cervical, and testicular malignancies. Average visit duration on OEE was shorter, and fewer readers surveyed OEE more than 15 minutes (4.5% vs. 14.9%, P users of web-based oncology resources are increasingly using the Internet to supplement their cancer knowledge. Limited available resources written in Spanish contribute to disparities in information access and disease outcomes. Spanish-speaking oncology readers differ from English-speaking readers in day and time of Internet browsing, visit duration, Internet search patterns, and types of cancers searched. By acknowledging these differences, content of web-based oncology resources can be developed to best target the needs of Spanish-speaking viewers.

This study documented baseline neurocognitive performance of 23,815 athletes on the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) test. Specifically, 9,733 Hispanic, Spanish-speaking athletes who completed the ImPACT test in English and 2,087 Hispanic, Spanish-speaking athletes who completed the test in Spanish were compared with 11,955 English-speaking athletes who completed the test in English. Athletes were assigned to age groups (13-15, 16-18). Results revealed a significant effect of language group (p Spanish-speaking athletes completing the test in Spanish scored more poorly than Spanish-speaking and English-speaking athletes completing the test in English, on all Composite scores and Total Symptom scores. Spanish-speaking athletes completing the test in English also performed more poorly than English-speaking athletes completing the test in English on three Composite scores. These differences in performance and reported symptoms highlight the need for caution in interpreting ImPACT test data for Hispanic Americans.

The Boston Naming Test (BNT) is a widely used measure of confrontation naming ability that has been criticized for its questionable construct validity for non-English speakers. This study investigated item difficulty and construct validity of the Spanish version of the BNT to assess cultural and linguistic impact on performance. Subjects were 1298 healthy Spanish speaking adults from Colombia. They were administered the 60- and 15-item Spanish version of the BNT. A Rasch analysis was computed to assess dimensionality, item hierarchy, targeting, reliability, and item fit. Both versions of the BNT satisfied requirements for unidimensionality. Although internal consistency was excellent for the 60-item BNT, order of difficulty did not increase consistently with item number and there were a number of items that did not fit the Rasch model. For the 15-item BNT, a total of 5 items changed position on the item hierarchy with 7 poor fitting items. Internal consistency was acceptable. Construct validity of the BNT remains a concern when it is administered to non-English speaking populations. Similar to previous findings, the order of item presentation did not correspond with increasing item difficulty, and both versions were inadequate at assessing high naming ability.

Neuropsychological measures have been widely used by clinicians to assist them in making judgments regarding a cognitively impaired patient's ability to independently perform important activities of daily living. However, important questions have been raised concerning the degree to which neuropsychological instruments can predict a broad array of specific functional capacities required in the home environment. In the present study, we examined 127 English-speaking and 56 Spanish-speaking patients with Alzheimer's disease (AD) and determined the extent to which various neuropsychological measures and demographic variables were predictive of performance on functional measures administered within the clinical setting. Among English-speaking AD patients, Block Design and Digit-Span of the WAIS-R, as well as tests of language were among the strongest predictors of functional performance. For Spanish-speakers, Block Design, The Mini-Mental State Evaluation (MMSE) and Digit Span had the optimal predictive power. When stepwise regression was conducted on the entire sample of 183 subjects, ethnicity emerged as a statistically significant predictor variable on one of the seven functional tests (writing a check). Despite the predictive power of several of the neuropsychological measures for both groups, most of the variability in objective functional performance could not be explained in our regression models. As a result, it would appear prudent to include functional measures as part of a comprehensive neuropsychological evaluation for dementia.

Although Hispanics have a documented high risk of limited health literacy, there is a scarcity of research with this population group, and particularly with Hispanic immigrants who generally confront language barriers that have been related to low health literacy. The National Action Plan to Improve Health Literacy identified community-based English-language instruction as a strategy that can facilitate a health literate society. However, the literature lacks discussion on this type of intervention. This randomized control trial aimed to test the feasibility of using conventional English-as-a-second-language (ESL) instruction for improving health literacy among Spanish-speaking adults. Objectives included the development, implementation, and evaluation of a health literacy/ESL curriculum. The Test of Functional Health Literacy in Adults (TOFHLA) in English was used to assess health literacy levels. Analyses included independent sample t test, chi-square, and multiple linear regression. A total of 155 people participated. Results showed a significantly higher increase in the TOFHLA posttest score in the intervention group (p = .01), and noticeable differences in health literacy levels between groups. Results indicate that ESL constitutes a promising venue for improving health literacy among Spanish-speaking adults. Incorporating health literacy-related content may provide additional benefits.

This special issue of the Journal of Learning Disabilities focuses on studies of writing disabilities in Spanish-speaking children. The World Health Organization (2001) included writing difficulties as one of the problems considered to constitute an impediment to school participation, a significant element in the normal developmental process of the child. In this introduction, I describe the background of a larger project promoted by the United Nations Educational, Scientific and Cultural Organization (UNESCO). This special series offers recent findings on writing disabilities in Spanish-Speaking children within the UNESCO project. The pilot study was carried out in the Canary Islands, an autonomous Spanish region located between three continents and composed of seven islands in the Atlantic Ocean. Most of the current empirical evidence on writing disabilities comes from English, a language with deep orthography; therefore, it is very relevant to investigate the writing process in Spanish, a language with shallow, fine-grained orthography. Included are a number of articles that form a conspectus on writing disabilities in the Spanish language. Topics center on early grade writing assessment, prevalence of writing disabilities, handwriting and keyboarding, transcription and text generation, graphonomic and handwriting analysis, and instructional practices with an learning disabled population.

To generate normative data for the Symbol Digit Modalities Test (SDMT) in Spanish-speaking pediatric populations. The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the SDMT as part of a larger neuropsychological battery. SDMT scores were normed using multiple linear regressions and standard deviations of residual values. Age, age2, sex, and mean level of parental education (MLPE) were included as predictors in the analyses. The final multiple linear regression models showed main effects for age in all countries, such that score increased linearly as a function of age. In addition, age2 had a significant effect in all countries, except in Honduras and Puerto Rico. Models indicated that children whose parent(s) had a MLPE >12 years of education obtained higher score compared to children whose parent(s) had a MLPE ≤12 years for Chile, Guatemala, Mexico, and Spain. Sex affected SDMT score for Paraguay and Spain. This is the largest Spanish-speaking pediatric normative study in the world, and it will allow neuropsychologists from these countries to have a more accurate interpretation of the SDMT with pediatric populations.

Objectives Social Anxiety Disorder (SAD) is one of the most common mental disorders in adolescence. Many validated psychometric tools are available to diagnose individuals with SAD efficaciously. However, there is a demand for shortened self-report instruments that identify adolescents at risk of developing SAD. We validate the Mini-SPIN and its diagnostic efficiency in overcoming this problem in Spanish-speaking adolescents in Spain. Methods The psychometric properties of the 3-item Mini-SPIN scale for adolescents were assessed in a community (study 1) and clinical sample (study 2). Results Study 1 consisted of 573 adolescents, and found the Mini-SPIN to have appropriate internal consistency and high construct validity. Study 2 consisted of 354 adolescents (147 participants diagnosed with SAD and 207 healthy controls). Data revealed that the Mini-SPIN has good internal consistency, high construct validity and adequate diagnostic efficiency. Conclusions Our findings suggest that the Mini-SPIN has good psychometric properties on clinical and healthy control adolescents and general population, which indicates that it can be used as a screening tool in Spanish-speaking adolescents. Cut-off scores are provided. PMID:26317695

The 2000 Pew reports became the impetus for the National Environmental Public Health Tracking (EPHT) Program, but there was no mention that Spanish-speaking persons are at increased risk of exposure to environmental hazards. To undertake successful EPHT outreach on Spanish-speaking persons (Hispanics), it is necessary to better understand their environmental health profile and barriers to health care access. Behavioral Risk Factor Surveillance System (BRFSS) survey questions were administered orally in Spanish to Spanish-speaking study participants. Volunteers were tested at a non-for-profit social service and referral agency in Baltimore. To control for acculturation, only Spanish-speaking persons who had lived in the United States for less than 10 years were selected. Responses to 40 BRFSS survey questions asked during the assessment and completion of 3 intervention activities. This study provides new information about Spanish-speaking persons, most of whom (85.3%) would not have been included in the landline administration of the BRFSS survey. Although 29.9% of the participants reported indoor pesticide use and another 9.2% reported outdoor pesticide use, lifetime (3.5%) and current (1.2%) asthma prevalence was significantly lower than asthma prevalence reported by Maryland Hispanics and all Maryland residents. There were significantly lower cholesterol screening (21.5%) and a significantly higher prevalence of diabetes (12.5%) in Spanish-speaking participants than in Maryland Hispanics and all Maryland residents. Among study participants, only 7.8% had health insurance and 39.9% reported that they could not see a doctor. Of the 3 outreach efforts completed, the most promising one involved asking Spanish-English-speaking health care professionals to distribute Spanish comic books about pesticides exposures and health outcomes in community settings where Spanish-only speakers and children were found.

Bystander cardiopulmonary resuscitation (CPR) is a vital link in the chain of survival for out-of-hospital cardiac arrest (OHCA); however, there are racial/ethnic disparities in the provision of bystander CPR. Approximately 32% of Hispanics perform CPR when confronted with cardiac arrest, whereas approximately 41% of non-Hispanics perform CPR. Public education, via the Internet, may be critical in improving the performance of bystander CPR among Hispanics. The objective of this study was to evaluate the availability and quality of CPR-related literature for primary Spanish-speaking individuals on the Internet. Two search engines (Google and Yahoo!) and a video-site (YouTube) were searched using the following terms: "resucitacion cardiopulmonar" and "reanimacion cardiopulmonar." Inclusion criteria were: education of CPR technique. Exclusion criteria were: instruction on pediatric CPR technique, failure to provide any instruction on CPR technique, or duplicated website. Data elements were collected on the content and quality of the websites and videos, such as assessing scene safety, verifying responsiveness, activating EMS, properly positioning hands on chest, performing accurate rate and depth of compressions. Of the 515 websites or videos screened, 116 met criteria for inclusion. The majority of websites (86%; 95% Confidence Interval [CI] 79-92%) educated viewers on traditional bystander CPR (primarily, 30:2 CPR), while only 14% (95% CI 9-21%) taught hands-only CPR. Of websites that used video (N=62), 84% were conducted in Spanish and 16% in English. The quality of CPR education was generally poor (median score of 3/6, IQR of 3.0). Only half of websites properly educated on how to check responsiveness, activate EMS and position hands on chest. Eighty-eight percent of websites failed to educate viewers on assessing scene safety. The majority of websites had improper or no education on both rate and depth of compressions (59% and 63%, respectively). Only 16% of

Much of the existing research on smoking outcome expectancies has been guided by the Smoking Consequences Questionnaire (SCQ ). Although the original version of the SCQ has been modified over time for use in different populations, none of the existing versions have been evaluated for use among Spanish-speaking Latino smokers in the United States. The present study evaluated the factor structure and predictive validity of the 3 previously validated versions of the SCQ--the original, the SCQ-Adult, and the SCQ-Spanish, which was developed with Spanish-speaking smokers in Spain--among Spanish-speaking Latino smokers in Texas. The SCQ-Spanish represented the least complex solution. Each of the SCQ-Spanish scales had good internal consistency, and the predictive validity of the SCQ-Spanish was partially supported. Nearly all the SCQ-Spanish scales predicted withdrawal severity even after controlling for demographics and dependence. Boredom Reduction predicted smoking relapse across the 5- and 12-week follow-up assessments in a multivariate model that also controlled for demographics and dependence. Our results support use of the SCQ-Spanish with Spanish-speaking Latino smokers in the United States.

Interpersonal trust between patient and nurse is important in patient-centered care. Trust development may be more difficult if the patient and nurse do not speak the same language. In this grounded theory study, Spanish-speaking Mexican American adults ( n = 20) hospitalized on a medical-surgical or obstetric unit in the Midwestern United States were interviewed. Through data analysis, a model of how trust develops between nurse and patient revealed eight categories and the core category Caring for Me Well Even When Not Understanding Me. The beginning phase had four categories: Asking for Help, Bothering, Communicating, and Understanding. The middle phase had two categories: Platicando (chatting) and Being Available. The end point category was Having Trust, and outcomes were Feeling Comfortable and Feeling Supported. The language barrier was a hindrance to trust development but the nurse's way of being (personality) was more important. Therefore, the patient did develop trust with nurses who did not speak Spanish.

The validity of the Fundación MacArthur Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Enunciados (IDHC:PE) was examined with twenty 20- and nineteen 28-month-old, typically developing, monolingual, Spanish-speaking children living in Mexico. One measure of vocabulary (number of words) and two measures of grammar (mean of the three longest utterances and grammatical complexity score) from the IDHC:PE were compared to behavioral measures of vocabulary (number of different words from a language sample and number of objects named in a confrontation naming task) and one behavioral measure of grammar (mean length of utterance from a language sample). Only vocabulary measures were assessed in the 20-month-olds because of floor effects on the grammar measures. Results indicated validity for assessing expressive vocabulary in 20-month-olds and expressive vocabulary and grammar in 28-month-olds.

HIV-related stigma has been associated with a reluctance to test for HIV among Latinos. This study assessed community HIV-related stigma within an emerging Latino immigrant receiving city. We conducted a brief survey among a convenience sample of 312 Spanish-speaking Latinos in Baltimore, Maryland. HIV-related stigma was assessed through six items. Associations between stigma items, socio-demographic characteristics, and HIV testing history were considered. Gender, education, and religiosity were significantly associated with stigmatizing HIV-related beliefs. For example, men were 3.4 times more likely to hold more than three stigmatizing beliefs than women, and were also twice as likely as women to report feeling hesitant to test for HIV for fear of people's reaction if the test is positive. These findings can help inform future stigma interventions in this community. In particular, we were able to distinguish between drivers of stigma such as fear and moralistic attitudes, highlighting specific actionable items.

This article describes the word reading skills in English and Spanish for a sample of 244 Spanish-speaking, English-learning (hence, bilingual) students in first grade and presents a predictive model for English word reading skills. The children in the study were assessed at the end of kindergarten and first grade, respectively. Data were gathered with 3 subtests of the Woodcock Language Proficiency Battery and a researcher-developed phonological awareness task. Results showed that, on average, children's English word reading skills were similar to monolingual norms whereas their Spanish word reading skills averaged 1 SD below the mean. English vocabulary, English phonological awareness, and Spanish word reading skills in kindergarten were found to be significant predictors of English word reading skills in first grade. Educational implications for screening language and reading skills and promising areas for targeted instruction for this population are discussed.

This longitudinal study examined the process of English reading comprehension at age 11 for 173 low achieving Spanish-speaking children. The influence of growth rates, from early childhood (age 4.5) to pre-adolescence (age 11), in vocabulary and word reading skills on this complex process were evaluated using structural equation modeling. Standardized measures of word reading accuracy and productive vocabulary were administered annually, in English and Spanish, and English reading comprehension measures were administered at age 11. Latent growth curve analyses revealed that English skills accounted for all unique variance in English reading comprehension outcomes. Further, expected developmental shifts in the influence of word reading and vocabulary skills over time were not shown, likely on account of students' below grade level reading comprehension achievement. This work underscores the need for theoretical models of comprehension to account for students' skill profiles and abilities.

Parent beliefs regarding food, health, and child feeding behaviors among Latinos have not been well-documented. A series of eight focus groups were conducted with English-speaking and Spanish-speaking low-income Latina mothers of preschoolers to investigate their beliefs regarding how food and food preparation are related to their children's health and to their own roles as mothers. Systematic content analysis using NUDIST 6 revealed seven themes discussed by the focus groups. Integration of these themes revealed three major areas of consideration: (1) a lack of connection between the domains of eating, overweight, and health outcomes; (2) the role of parent modeling of eating behaviors; and (3) the use of feeding strategies that may not be conducive to the development of healthy eating behaviors. Furthermore, the data suggest that there are important distinctions among Latinos based on language preference, and that a "one-size-fits-all" approach to modeling Latino mothers' feeding beliefs may not be appropriate.

The state of Oklahoma, known for destructive tornados, has a native Spanish-speaking (NSS) population of approximately 180,241, of which 50% report being able to speak English "very well" (US Census Bureau). With almost 50% of these native Spanish-speaking persons being limited English proficient (LEP), their reception of tornado hazard communications may be restricted. This study conducted in northeast Oklahoma (USA) evaluates the association between native language and receiving tornado hazard communications. This study was a cross-sectional survey conducted among a convenience sample of NSS and native English-speaking (NES) adults at Xavier Clinic and St. Francis Trauma Emergency Center in Tulsa, OK, USA from September 2009 through December 2009. Of the 82 surveys administered, 80 were returned, with 40 NES and 40 NSS participants. A scoring system (Severe Weather Information Reception (SWIR)) was developed to quantify reception of hazard information among the study participants (1-3 points=poor reception, 4-5=adequate reception, 6-8=excellent reception). Pearson's chi-squared test was used to calculate differences between groups with Yates' continuity correction applied where appropriate, and SWIR scores were analyzed using ANOVA. P-valuestornado siren. NSS were less likely to have Internet access (Ptornado warning reception between NSS and NES. Poor English proficiency was noted to be 75% among NSS, which is approximately 25% more than estimated by the US Census Bureau. This study demonstrates a need for emergency managers to recognize when appropriate and overcome communication disparities among limited English proficient populations.

Psychometricians and test developers evaluate standardized tests for potential bias against groups of test-takers by using differential item functioning (DIF). English language learners (ELLs) are a diverse group of students whose native language is not English. While they are still learning the English language, they must take their standardized tests for their school subjects, including science, in English. In this study, linguistic complexity was examined as a possible source of DIF that may result in test scores that confound science knowledge with a lack of English proficiency among ELLs. Two years of fifth-grade state science tests were analyzed for evidence of DIF using two DIF methods, Simultaneous Item Bias Test (SIBTest) and logistic regression. The tests presented a unique challenge in that the test items were grouped together into testlets---groups of items referring to a scientific scenario to measure knowledge of different science content or skills. Very large samples of 10, 256 students in 2006 and 13,571 students in 2007 were examined. Half of each sample was composed of Spanish-speaking ELLs; the balance was comprised of native English speakers. The two DIF methods were in agreement about the items that favored non-ELLs and the items that favored ELLs. Logistic regression effect sizes were all negligible, while SIBTest flagged items with low to high DIF. A decrease in socioeconomic status and Spanish-speaking ELL diversity may have led to inconsistent SIBTest effect sizes for items used in both testing years. The DIF results for the testlets suggested that ELLs lacked sufficient opportunity to learn science content. The DIF results further suggest that those constructed response test items requiring the student to draw a conclusion about a scientific investigation or to plan a new investigation tended to favor ELLs.

To generate normative data for the Stroop Word-Color Interference test in Spanish-speaking pediatric populations. The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the Stroop Word-Color Interference test as part of a larger neuropsychological battery. The Stroop Word, Stroop Color, Stroop Word-Color, and Stroop Interference scores were normed using multiple linear regressions and standard deviations of residual values. Age, age2, sex, and mean level of parental education (MLPE) were included as predictors in the analyses. The final multiple linear regression models showed main effects for age on all scores, except on Stroop Interference for Guatemala, such that scores increased linearly as a function of age. Age2 affected Stroop Word scores for all countries, Stroop Color scores for Ecuador, Mexico, Peru, and Spain; Stroop Word-Color scores for Ecuador, Mexico, and Paraguay; and Stroop Interference scores for Cuba, Guatemala, and Spain. MLPE affected Stroop Word scores for Chile, Mexico, and Puerto Rico; Stroop Color scores for Mexico, Puerto Rico, and Spain; Stroop Word-Color scores for Ecuador, Guatemala, Mexico, Puerto Rico and Spain; and Stroop-Interference scores for Ecuador, Mexico, and Spain. Sex affected Stroop Word scores for Spain, Stroop Color scores for Mexico, and Stroop Interference for Honduras. This is the largest Spanish-speaking pediatric normative study in the world, and it will allow neuropsychologists from these countries to have a more accurate approach to interpret the Stroop Word-Color Interference test in pediatric populations.

Veterinary schools and colleges generally include communication skills training in their professional curriculum, but few programs address challenges resulting from language gaps between pet owners and practitioners. Due to shifting US demographics, small animal veterinary practices must accommodate an increasing number of limited English proficient (LEP) Spanish-speaking pet owners (SSPOs). A national survey was conducted to assess the interest and preparedness of US veterinary students to communicate with LEP SSPOs when they graduate. This online survey, with more than 2,000 first-, second-, and third-year US veterinary students, revealed that over 50% of students had worked at a practice or shelter that had LEP Spanish-speaking clients. Yet fewer than 20% of these students described themselves as prepared to give medical information to an LEP SSPO. Over three-fourths of respondents agreed that communication with LEP SSPOs was important for veterinarians in general, and two-thirds agreed that communication with LEP SSPOs was important for themselves personally. Ninety percent of students who described themselves as conversant in Spanish agreed that they would be able to communicate socially with SSPOs, while only 55% said they would be able to communicate medically with such clients. Overall, two-thirds of students expressed interest in taking Spanish for Veterinary Professionals elective course while in school, with the strongest interest expressed by those with advanced proficiency in spoken Spanish. Bridging language gaps has the potential to improve communication with LEP SSPOs in the veterinary clinical setting and to improve patient care, client satisfaction, and the economic health of the veterinary profession.

Hispanics, particularly those with limited English proficiency, are underrepresented in psychiatric clinical research studies. We developed a bilingual and bicultural research clinic dedicated to the recruitment and treatment of Spanish-speaking subjects in the Predictors of Remission in Depression to Individual and Combined Treatments (PReDICT) study, a large clinical trial of treatment-naïve subjects with major depressive disorder (MDD). Demographic and clinical data derived from screening evaluations of the first 1,174 subjects presenting for participation were compared between the Spanish-speaking site (N = 275) and the primary English-speaking site (N = 899). Reasons for ineligibility (N = 888) for the PReDICT study were tallied for each site. Compared to English speakers, Spanish speakers had a lower level of education and were more likely to be female, uninsured, and have uncontrolled medical conditions. Clinically, Spanish speakers demonstrated greater depression severity, with higher mean symptom severity scores, and a greater number of previous suicide attempts. Among the subjects who were not randomized into the PReDICT study, Spanish-speaking subjects were more likely to have an uncontrolled medical condition or refuse participation, whereas English-speaking subjects were more likely to have bipolar disorder or a non-MDD depressive disorder. Recruitment of Hispanic subjects with MDD is feasible and may enhance efforts at signal detection, given the higher severity of depression among Spanish-speaking participants presenting for clinical trials. Specific approaches for the recruitment and retention of Spanish-speaking participants are required. © 2013 Wiley Periodicals, Inc.

Internet-based developmental screening is being implemented in pediatric practices across the United States. Little is known about the application of this technology in poor urban populations. We describe here the results of focus groups, surveys, and in-depth interviews during home visits with families served by an urban safety-net organization to address the question of whether it is possible to use Internet or e-mail communication for medical previsit engagement in a population that is majority Hispanic, of low socioeconomic status, and has many non-English-speaking families. This study included families in 4 clinics within a safety-net health care system. The study design included the use of (1) parental surveys (n = 200) of a convenience sample of parents whose children received primary care in the clinics, (2) focus groups (n = 7 groups) with parents, and (3) in-depth interviews during home visits with 4 families. We used χ(2) and multivariate analyses to compare Internet access in English- and Spanish-speaking families. Standard qualitative methods were used to code focus-group texts and identify convergent themes. In multivariate analysis, independent factors associated with computer use were English versus Spanish language (odds ratio: 3.2 [95% confidence interval: 1.4-6.9]) and education through at least high school (odds ratio: 4.7 [95% confidence interval: 2.3-9.7]). In focus groups, the concept of parental previsit work, such as developmental screening tests, was viewed favorably by all groups. However, many parents expressed reservations about doing this work by using the Internet or e-mail and stated a preference for either paper or telephone options. Many Spanish-speaking families discussed lack of access to computers and printers. In this economically disadvantaged population, language and maternal education were associated with access to the Internet. Given the potential power of previsit work to tailor well-child visits to the needs of
This paper creates a theoretical framework of analysis for understanding the concerns and methods of ecological designers. Various definitions of ecological design are reviewed to show its basis in natural ecological systems, either as analog or as context, and its purpose as creating sustainability. Ecological design methods are categorized as conceptual, factual, or integrative. The characteristics and definitions of these methods are explained and several practitioners and theorists classified. Lyle's concept of ecosystematic order is used to show the basis of methods in either a building architecture or a landscape architecture perspective. A matrix is generated and applied to a representative of each category, showing the concerns of each in terms of the integration of human and natural ecosystem structure, function, and location

The purpose of the study was to describe perception of risk for developing diabetes among foreign-born Spanish-speaking US Latinos. Participants (N = 146), recruited at food-pantry distribution events and free clinics, were surveyed using the Risk Perception Survey for Developing Diabetes in Spanish. Type 2 diabetes risk factors measured included body mass index, physical activity, and A1C. Sample characteristics were mean (SD) age of 39.5 (9.9) years, 58% with less than a high school graduate-level education, and 65% with a family income less than $15,000/year. Prevalence of risk factors was 81% overweight or obese, 47% less than 150 minutes/week moderate/vigorous-intensity physical activity, and 12% A1C consistent with prediabetes. Of the 135 participants with complete data, 31% perceived a high/moderate risk for developing diabetes. In univariate logistic regression analyses, 9 of 18 potential variables were significant (P perception of risk. When these 9 variables were entered into a multiple logistic regression model, 5 were significant predictors of perception of risk: history of gestational diabetes, high school graduate or above, optimistic bias, worry, and perceived personal disease risk. Use of the Spanish-language translation of the Risk Perception Survey for Developing Diabetes revealed factors influencing perception of risk for developing diabetes. Results can be used to promote culturally acceptable type 2 diabetes primary prevention strategies and provide a useful comparison to other populations. © 2016 The Author(s).
The primary objective of the current investigation was to examine the concurrent and predictive validity of a parent vocabulary checklist with young Spanish speaking children of Mexican immigrants. This study implemented a longitudinal approach. Nineteen families participated when children were 15-16 months of age, and then again at 30-32 months of age. The Spanish version of the MacArthur Communicative Development Inventory (Inventarios del Desarrollo de Habilidades Communicativas, INV) and spontaneous language samples collected during naturalistic play were used to examine the relationship between observed and reported vocabulary. Vocabulary reported through the INV-II and vocabulary observed at 30-32 months were significantly correlated, suggesting that the INV-II captures a valid representation of vocabulary at this age. Comparatively, vocabulary reported on the INV-I, was not correlated with observed vocabulary at 15-16 months of age or reported or observed vocabulary at 30-32 months of age. These results suggest that the INV-I, when used with 14-16-month-olds, demonstrates limited concurrent and predictive validity. Implications for the clinical use of the INV-I and INV-II are presented.

In this study we evaluated the predictive validity of conceptual scoring. Two independent samples of Spanish-speaking language minority preschoolers (Sample 1: N = 96, mean age = 54·51 months, 54·3% male; Sample 2: N = 116, mean age = 60·70 months, 56·0% male) completed measures of receptive, expressive, and definitional vocabulary in their first (L1) and second (L2) languages at two time points approximately 9-12 months apart. We examined whether unique L1 and L2 vocabulary at time 1 predicted later L2 and L1 vocabulary, respectively. Results indicated that unique L1 vocabulary did not predict later L2 vocabulary after controlling for initial L2 vocabulary. An identical pattern of results emerged for L1 vocabulary outcomes. We also examined whether children acquired translational equivalents for words known in one language but not the other. Results indicated that children acquired translational equivalents, providing partial support for the transfer of vocabulary knowledge across languages.

To generate normative data on the Stroop Test across 11 countries in Latin America, with country-specific adjustments for gender, age, and education, where appropriate. The sample consisted of 3,977 healthy adults who were recruited from Argentina, Bolivia, Chile, Cuba, El Salvador, Guatemala, Honduras, Mexico, Paraguay, Peru, and, Puerto Rico. Each subject was administered the Stroop Test, as part of a larger neuropsychological battery. A standardized five-step statistical procedure was used to generate the norms. The final multiple linear regression models explained 14-36% of the variance in Stroop Word scores, 12-41% of the variance in the Stoop Color, 14-36% of the variance in the Stroop Word-Color scores, and 4-15% of variance in Stroop Interference scores. Although t-tests showed significant differences between men and women on the Stroop test, none of the countries had an effect size larger than 0.3. As a result, gender-adjusted norms were not generated. This is the first normative multicenter study conducted in Latin America to create norms for the Stoop Test in a Spanish-Speaking sample. This study will therefore have important implications for the future of neuropsychology research and practice throughout the region.

Nutrition is important for preventing and treating chronic diseases highly prevalent among Latinos, yet no tool exists for measuring nutrition literacy among Spanish speakers. This study aimed to adapt the validated Nutrition Literacy Assessment Instrument for Spanish-speaking Latinos. This study was developed in two phases: adaptation and validity testing. Adaptation included translation, expert item content review, and interviews with Spanish speakers. For validity testing, 51 participants completed the Short Assessment of Health Literacy-Spanish (SAHL-S), the Nutrition Literacy Assessment Instrument in Spanish (NLit-S), and socio-demographic questionnaire. Validity and reliability statistics were analyzed. Content validity was confirmed with a Scale Content Validity Index of 0.96. Validity testing demonstrated NLit-S scores were strongly correlated with SAHL-S scores (r = 0.52, p internal consistency was excellent (Cronbach's α = 0.92). The NLit-S demonstrates validity and reliability for measuring nutrition literacy among Spanish-speakers.

Speech perception involves the integration of auditory and visual articulatory information, and thus requires the perception of temporal synchrony between this information. There is evidence that children with specific language impairment (SLI) have difficulty with auditory speech perception but it is not known if this is also true for the integration of auditory and visual speech. Twenty Spanish-speaking children with SLI, twenty typically developing age-matched Spanish-speaking children, and twenty Spanish-speaking children matched for MLU-w participated in an eye-tracking study to investigate the perception of audiovisual speech synchrony. Results revealed that children with typical language development perceived an audiovisual asynchrony of 666 ms regardless of whether the auditory or visual speech attribute led the other one. Children with SLI only detected the 666 ms asynchrony when the auditory component preceded [corrected] the visual component. None of the groups perceived an audiovisual asynchrony of 366 ms. These results suggest that the difficulty of speech processing by children with SLI would also involve difficulties in integrating auditory and visual aspects of speech perception.

In the U.S., poverty has been linked to both obesity and disease burden. Latinos in the U.S. are disproportionately affected by poverty, and over the past 10 years, the percentage of overweight U.S. Latino youth has approximately doubled. Buying low-cost food that is calorie-dense and filling has been linked to obesity. Low-income individuals tend to favor energy-dense foods because of their low cost, and economic decisions made during food purchasing have physiologic repercussions. Diets based on energy-dense foods tend to be high in processed staples, such as refined grains, added sugars, and added fats. These diets have been linked to a higher risk of obesity, type 2 diabetes, and cardiovascular disease. This pilot study conducted ethnographic qualitative analyses combined with quantitative analyses to understand grocery shopping practices among 20 Spanish-speaking, low-income Latino families. The purpose was to analyze food selection practices in order to determine the effect of nutrition education on changes in shopping practices to later develop educational tools to promote selection of healthier food options. Participants received tailored, interactive, nutrition education during three to five home visits and a supermarket tour. Grocery store receipts for grocery purchases collected at baseline and at the end of the project were analyzed for each family to extract nutritional content of purchased foods. Nutritional content was measured with these factors in mind: quantity, calories, fats, carbohydrates, fiber, protein, and percentage of sugary beverages and processed food. Data were collected in 2010-2011 and analyzed in 2011-2012. After receiving between three and five home-based nutrition education sessions and a supermarket tour over a 6-month period, many families adopted instructions on buying budget-friendly, healthier alternative foods. Findings indicate that participating families decreased the total number of calories and calories per dollar

This article describes the quantitative findings of a mixed-methods study that examined the relationship among knowledge, self-efficacy, health promoting behaviors, and type 2 diabetes self-management among recent Spanish-speaking, limited English proficient immigrants to the US. This population is at risk for both a higher incidence of disease and increased barriers to successful disease management compared to the general US population. Distinguishing aspects of this study compared to the available literature are the comprehensive nature of the data collected, the theoretical component, and the analysis and modeling approach. Social cognitive theory provides the framework for the study design and analysis. An innovative community-based recruiting strategy was used, a broad range of physiological measures related to health were observed, and instruments related to knowledge, self-efficacy, and healthy lifestyle behaviors were administered orally in Spanish to 30 participants. A broad range of statistical analysis methods was applied to the data, including a set of three structural equation models. The study results are consistent with the importance of education, health knowledge, and healthy lifestyle practices for type 2 diabetes self-management. With the usual cautions associated with applying structural equation modeling to modest sample sizes, multiple elements of the posited theoretical model were consistent with the data collected. The results of the investigation of this under-studied population indicate that, on average, participants were not effectively managing their disease. The results suggest that clinical interventions focused on improving knowledge, nutrition, and physical activity, reducing stress, and leveraging the importance of interpersonal relations could be effective intervention strategies to improve self-management among this population.

Full Text Available OBJECTIVE: To describe a 10-year proof-of-concept smoking cessation research program evaluating the reach of online health interventions throughout the Americas. METHODS: Recruitment occurred from 2002 - 2011, primarily using Google.com AdWords. Over 6 million smokers from the Americas entered keywords related to smoking cessation; 57 882 smokers (15 912 English speakers and 41 970 Spanish speakers were recruited into online self-help automated intervention studies. To examine disparities in utilization of methods to quit smoking, cessation aids used by English speakers and Spanish speakers were compared. To determine whether online interventions reduce disparities, abstinence rates were also compared. Finally, the reach of the intervention was illustrated for three large Spanish-speaking countries of the Americas-Argentina, Mexico, and Peru-and the United States of America. RESULTS: Few participants had utilized other methods to stop smoking before coming to the Internet site; most reported using no previous smoking cessation aids: 69.2% of Spanish speakers versus 51.8% of English speakers (P < 0.01. The most used method was nicotine gum, 13.9%. Nicotine dependence levels were similar to those reported for in-person smoking cessation trials. Overall observed quit rate for English speakers was 38.1% and for Spanish speakers, 37.0%; quit rates in which participants with missing data were considered to be smoking were 11.1% and 10.6%, respectively. Neither comparison was significantly different. CONCLUSIONS: The systematic use of evidence-based Internet interventions for health problems could have a broad impact throughout the Americas, at little or no cost to individuals or to ministries of health.

Clinic-based studies suggest that dementia is diagnosed at older ages in bilinguals compared with monolinguals. The current study sought to test this hypothesis in a large, prospective, community-based study of initially nondemented Hispanic immigrants living in a Spanish-speaking enclave of northern Manhattan. Participants included 1,067 participants in the Washington/Hamilton Heights Inwood Columbia Aging Project (WHICAP) who were tested in Spanish and followed at 18-24 month intervals for up to 23 years. Spanish-English bilingualism was estimated via both self-report and an objective measure of English reading level. Multilevel models for change estimated the independent effects of bilingualism on cognitive decline in 4 domains: episodic memory, language, executive function, and speed. Over the course of the study, 282 participants developed dementia. Cox regression was used to estimate the independent effect of bilingualism on dementia conversion. Covariates included country of origin, gender, education, time spent in the United States, recruitment cohort, and age at enrollment. Independent of the covariates, bilingualism was associated with better memory and executive function at baseline. However, bilingualism was not independently associated with rates of cognitive decline or dementia conversion. Results were similar whether bilingualism was measured via self-report or an objective test of reading level. This study does not support a protective effect of bilingualism on age-related cognitive decline or the development of dementia. In this sample of Hispanic immigrants, bilingualism is related to higher initial scores on cognitive tests and higher educational attainment and may not represent a unique source of cognitive reserve.

The purpose of this study is to contribute to the understanding and explanation of the science achievement gap between Spanish-speaking English language learners (ELLs) and their mainstream peers. The sample of purposefully selected participants (N = 23) included students representing eight Spanish-speaking countries who attended three middle schools (grades 6th-8th), 11 boys and 12 girls, with different years of schooling in the United States, English proficiency levels, and science achievement levels. Data gathering strategies included individual interviews with participants, classroom observations, and analysis of secondary data sources on students' English language proficiency and science achievement. Data interpretation strategies using a critical-interpretive perspective consisted of coding and narrative analysis, including analyses of excerpts and case studies. Two major findings emerge from the study: (1) An inverse relation between participants' number of years of exposure to science learning in an English-only learning environment and their science achievement levels; and (2) specific participant-identified problems, such as learning the science vocabulary, writing in science, the use of mathematics in science, and the lack of sense making in the science classroom. Key recommendations comprise: (1) Acknowledging the value of dual language education; (2) supporting the science-literacy connection; (3) ensuring high-quality science through research-informed instructional strategies; and (4) assessing ELLs' science achievement.

Children's self-regulation, including components of executive function such as inhibitory control, is related concurrently and longitudinally with elementary school children's reading and math abilities. Although several recent studies have examined links between preschool children's self-regulation or executive function and their academic skill development, few included large numbers of Spanish-speaking language-minority children. Among the fastest growing segments of the U.S. school-age population, many of these children are at significant risk of academic difficulties. We examined the relations between inhibitory control and academic skills in a sample containing a large number of Spanish-speaking preschoolers. Overall, the children demonstrated substantial academic risk based on preschool-entry vocabulary scores in the below-average range. Children completed assessments of language, literacy, and math skills in English and Spanish, when appropriate, at the start and end of their preschool year, along with a measure of inhibitory control, the Head-Toes-Knees-Shoulders task, which was administered at the start of the preschool year in the child's dominant conversational language. Scores on this last measure were lower for children for whom it was administered in Spanish. For both English and Spanish outcomes, those scores were significantly and uniquely associated with higher scores on measures of phonological awareness and math skills but not vocabulary or print knowledge skills.

The objective of the present study was the validation and scaling of the Plutchik's Violence Risk Scale (EV) in adolescent Spanish-speaking population. For this purpose, a sample of adolescents from El Salvador, Mexico and Spain was obtained. The sample consisted of 1035 participants with a mean age of 16.2. There were 450 adolescents from forensic population (those who committed crime) and 585 adolescents from normal population (no crime committed). The internal consistency of the EV was estimated by Cronbach's alpha coefficient and with a value of 0.782. As for validity, the factorial structures found explain a large proportion of the variance (53.385%); the convergent validity was estimated by the correlation between the dimensions found, the EV and sociodemographic, criminological and personality variables. The developed scales are presented, for the first time in a cross-cultural sample, differentiating between gender and continent. Consequently, the obtained results suggest that the EV is a valid and reliable instrument within adolescent Spanish-speaking population. Furthermore, it is a quick scale, easy to apply, which is something valuable in forensic assessment.

Purpose The purpose of this study was to examine the reliability and validity of a Spanish version of the Beliefs about Medicines Questionnaire (BMQ) as a measure to evaluate beliefs about medications and to differentiate adherent from nonadherent patients among low-income Latino patients with diabetes in the United States. Methods Seventy-three patients were administered the BMQ and surveyed for evidence of medication nonadherence. Internal consistency of the BMQ was assessed by Cronbach's alpha along with performing a confirmatory factor analysis. Criterion validity was assessed by comparing mean scores on 3 subscales of the BMQ (General Overuse, General Harm, and Specific Necessity-Concerns difference score) between adherent patients and patients reporting nonadherence for 3 different reasons (unintentional nonadherence, cost-related nonadherence, and nonadherence due to reasons other than cost) using independent samples t tests. Results The BMQ is a reliable instrument to examine beliefs about medications in this Spanish-speaking population. Construct validity testing shows nearly identical factor loading as the original construct map. General Overuse scores were significantly more negative for patients reporting each reason for nonadherence compared with their adherent counterparts. Necessity-Concerns difference scores were significantly more negative for patients reporting nonadherence for reasons other than cost compared with those who did not report this reason for nonadherence. Conclusion The Spanish version of the BMQ is appropriate to assess beliefs about medications in Latino patients with type 2 diabetes in the United States and may help identify patients who become nonadherent to medications for reasons other than out-of-pocket costs.

The National Institutes of Health Toolbox Emotion Battery (NIHTB-EB) is a "common currency", computerized assessment developed to measure the full spectrum of emotional health. Though comprehensive, the NIHTB-EB's 17 scales may be unwieldy for users aiming to capture more global indices of emotional functioning. NIHTB-EB was administered to 1,036 English-speaking and 408 Spanish-speaking adults as a part of the NIH Toolbox norming project. We examined the factor structure of the NIHTB-EB in English- and Spanish-speaking adults and developed factor analysis-based summary scores. Census-weighted norms were presented for English speakers, and sample-weighted norms were presented for Spanish speakers. Exploratory factor analysis for both English- and Spanish-speaking cohorts resulted in the same 3-factor solution: 1) negative affect, 2) social satisfaction, and 3) psychological well-being. Confirmatory factor analysis supported similar factor structures for English- and Spanish-speaking cohorts. Model fit indices fell within the acceptable/good range, and our final solution was optimal compared to other solutions. Summary scores based upon the normative samples appear to be psychometrically supported and should be applied to clinical samples to further validate the factor structures and investigate rates of problematic emotions in medical and psychiatric populations.
Full Text Available The aim of this study was to examine the relationships among vocabulary knowledge, phonological representations and phonological sensitivity in 80 Spanish-speaking preschool children from middle- and low-SES families. Significant social class differences were obtained on all tasks except syllable matching. Regression analyses were carried out to test the predictive power of vocabulary knowledge and accuracy of phonological representations on the phonological sensitivity measures. Receptive vocabulary predicted rhyme identification. Syllable matching was predicted by a task tapping accuracy of phonological representations. The fact that rhyme identification was predicted by vocabulary knowledge but syllable matching was predicted by a measure tapping accuracy of phonological representations in both groups suggests that early lexical development sets the stage for the development of the lower levels of phonological sensitivity but identification of smaller units requires more accurate and segmented phonological representations.
Full Text Available Observable disruptions in spontaneous speech are among the most prominent characteristics of aphasia. The potential of language production analyses in discourse contexts to reveal subtle language deficits has been progressively exploited, becoming essential for diagnosing language disorders (Vermeulen et al., 1989; Goodglass et al., 2000; Prins and Bastiaanse, 2004; Jaecks et al., 2012. Based on previous studies, short and/or fragmentary utterances, and consequently a shorter MLU, are expected in the speech of individuals with aphasia, together with a large proportions of incomplete sentences and a limited use of embeddings. Fewer verbs with a lower diversity (lower type/token ratio and fewer internal arguments are also predicted, as well as a low proportion of inflected verbs (Bastiaanse and Jonkers, 1998. However, this profile comes mainly from the study of individuals with prototypical aphasia types, mainly Broca’s aphasia, raising the question of how accurate spontaneous speech is to pinpoint deficits in individuals with less clear diagnoses. To address this question, we present the results of a spontaneous speech analysis of 25 Spanish-speaking subjects: 10 individuals with aphasia (IWAs, 7 male and 3 female (mean age: 64.2 in neural stable condition (> 1 year post-onset who suffered from a single CVA in the left hemisphere (Rosell, 2005, and 15 non-brain-damaged matched speakers (NBDs. In the aphasia group, 7 of the participants were diagnosed as non-fluent (1 motor aphasia, 4 transcortical motor aphasia or motor aphasia with signs of transcorticality, 2 mixed aphasia with motor predominance, and 3 of them as fluent (mixed aphasia with anomic predominance. The protocol for data collection included semi-standardized interviews, in which participants were asked 3 questions evoking past, present, and future events (last job, holidays, and hobbies. 300 words per participant were analyzed. The MLU over the total 300 words revealed a decreased

In this study, we evaluated the extent to which regional history has shaped the social identity nomenclature in New Mexicans of Spanish-speaking descent (NMSD). We asked 507 NMSD to list the social-identity terms they used to describe themselves and their parents, and we examined the correspondence between these choices and family ties to the region, birthplace, and continental ancestry. NMSD frequently identified using the regional terms "Nuevomexicano/a" (15%) and "Spanish" (12%). These individuals reported family ties to the region that predate New Mexican statehood. They and their parents were frequently born in New Mexico, frequently chose the other of the two terms as a secondary descriptor, and frequently ascribed one of the two terms to their parents. About 10% of NMSD identified as "Mexican American" and "Mexican." About 25% of these individuals, and more than half of their parents, were born in Mexico. They also frequently chose the other of the two terms as a secondary descriptor and frequently ascribed one of the two terms to their parents. Compared to NMSD who identified as "Mexican" and "Mexican American," individuals who identified as "Nuevomexicano/a" and "Spanish" had higher European ancestry and lower Native American and African ancestry. Our results also suggest that the term "Hispanic," frequently chosen as both a primary and secondary social identity term by NMSD, may, as it continues to rise in prominence, mask more deeply rooted and potential socially relevant aspects of social identity in New Mexico. More broadly, these results indicate that regional history influences social identity nomenclatures in ways that are potentially incompatible with US Office of Management and Budget standards. This incompatibility may adversely affect the ability of researchers in the social sciences to assess the causes of social inequality and health disparities in individuals of Spanish-speaking descent in different regions of the United States. We argue that

Use of high-volume hydraulic fracturing (HVHF) in unconventional reservoirs to recover previously inaccessible oil and natural gas is rapidly expanding in North America and elsewhere. Although hydraulic fracturing has been practiced for decades, the advent of more technologically advanced horizontal drilling coupled with improved slickwater chemical formulations has allowed extensive natural gas and oil deposits to be recovered from shale formations. Millions of liters of local groundwaters are utilized to generate extensive fracture networks within these low-permeability reservoirs, allowing extraction of the trapped hydrocarbons. Although the technology is relatively standardized, the geographies and related policies and regulations guiding these operations vary markedly. Some ecosystems are more at risk from these operations than others because of either their sensitivities or the manner in which the HVHF operations are conducted. Generally, the closer geographical proximity of the susceptible ecosystem to a drilling site or a location of related industrial processes, the higher the risk of that ecosystem being impacted by the operation. The associated construction of roads, power grids, pipelines, well pads, and water-extraction systems along with increased truck traffic are common to virtually all HVHF operations. These operations may result in increased erosion and sedimentation, increased risk to aquatic ecosystems from chemical spills or runoff, habitat fragmentation, loss of stream riparian zones, altered biogeochemical cycling, and reduction of available surface and hyporheic water volumes because of withdrawal-induced lowering of local groundwater levels. The potential risks to surface waters from HVHF operations are similar in many ways to those resulting from agriculture, silviculture, mining, and urban development. Indeed, groundwater extraction associated with agriculture is perhaps a larger concern in the long term in some regions. Understanding the

Spanish-speaking Latinas have some of the lowest rates of meeting physical activity guidelines in the U.S. and are at high risk for many related chronic diseases. The purpose of the current study was to examine the maintenance of a culturally and individually-tailored Internet-based physical activity intervention for Spanish-speaking Latinas. Inactive Latinas (N = 205) were randomly assigned to a 6-month Tailored Physical Activity Internet Intervention or a Wellness Contact Control Internet Group, with a 6-month follow-up. Maintenance was measured by assessing group differences in minutes per week of self-reported and accelerometer measured moderate to vigorous physical activity (MVPA) at 12 months after baseline and changes in MVPA between the end of the active intervention (month 6) and the end of the study (month 12). Potential moderators of the intervention were also examined. Data were collected between 2011 and 2014, and were analyzed in 2015 at the University of California, San Diego. The Intervention Group engaged in significantly more minutes of MVPA per week than the Control Group at the end of the maintenance period for both self-reported (mean diff. = 30.68, SE = 11.27, p = .007) and accelerometer measured (mean diff. = 11.47, SE = 3.19, p = .01) MVPA. There were no significant between- or within-group changes in MVPA from month 6 to 12. Greater intervention effects were seen for those with lower BMI (BMI × intervention = -6.67, SE = 2.88, p = .02) and lower perceived places to walk to in their neighborhood (access × intervention = -43.25, SE = 19.07, p = .02), with a trend for less family support (social support × intervention = -3.49, SE = 2.05, p = .08). Acculturation, health literacy, and physical activity related psychosocial variables were not significant moderators of the intervention effect during the maintenance period. Findings from the current study support the efficacy of an Internet

We examined the role of language and culture in the interactions between Spanish-speaking Latino patients with poorly controlled diabetes - a fast-growing population in the United States - and their primary care providers. We conducted four focus groups with 36 non-US born Spanish-speaking patients with elevated HbA1c. Participants were insured health plan members with either English-speaking (2 groups) or Spanish-speaking (2 groups) primary care providers. Moderated discussions focused on visit preparation, communication during visit, and role of other care team members. Key themes derived from these discussions were then linked to corresponding Latino cultural constructs. Patients had a mean age of 57.9 (±11.2) years and last measured HbA1c was 8.6% (1.5%). Two communication-related themes (reluctance to switch providers and use of intermediaries) and two visit-related themes (provider-driven visit agendas and problem-based visits) emerged from our analyses. These themes reflected the cultural constructs of confianza (trust), familismo (family), respeto (deference), and simpatía (harmonious relationship). Trust in the patient-provider relationship led many participants to remain with English-speaking providers who treated them well. Patients with either language concordant and discordant providers reported reliance on family or other intermediaries to close communication gaps. Deference to physician expertise and authority led to visit expectations that it is the doctor's job to know what to ask and that visits were intended to address specific, often symptom-driven problems. Spanish-speaking Latino patients' cultural expectations play an important role in framing their primary care interactions. Recognizing culturally influenced visit expectations is an important step toward improving patient-provider communication.

Introduction Advance care planning (ACP) is a process that allows patients to identify their goals for medical care. Traditionally, ACP has focused on completing advance directives; however, we have expanded the ACP paradigm to also prepare patients to communicate their wishes and make informed decisions. To this end, we created an ACP website called PREPARE (http://www.prepareforyourcare.org) to prepare diverse English-speaking and Spanish-speaking older adults for medical decision-making. H...

To explore parental beliefs and attitudes about confidential services for their teenagers; and to develop an instrument to assess these beliefs and attitudes that could be used among English and Spanish speakers. The long-term goal is to use this research to better understand and evaluate interventions to improve parental knowledge and attitudes toward their adolescent's access and utilization of comprehensive confidential health services. The instrument was developed using an extensive literature review and theoretical framework followed by qualitative data from focus groups and in-depth interviews. It was then pilot tested with a random sample of English- and Spanish-speaking parents and further revised. The final instrument was administered to a random sample of 1,000 mothers. The psychometric properties of the instrument were assessed for Spanish and English speakers. The instrument consisted of 12 scales. Most Cronbach alphas were >.70 for Spanish and English speakers. Fewer items for Spanish speakers "loaded" for the Responsibility and Communication scales. Parental Control of Health Information failed for Spanish speakers. The Parental Attitudes of Adolescent Confidential Health Services Questionnaire (PAACS-Q) contains 12 scales and is a valid and reliable instrument to assess parental knowledge and attitudes toward confidential health services for adolescents among English speakers and all but one scale was applicable for Spanish speakers. More research is needed to understand key constructs with Spanish speakers. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

Investigators have the responsibility to ensure that prospective participants are fully informed about a research protocol prior to consenting to participate, yet many researchers face challenges when obtaining consent, since the majority of the general population has limited or no familiarity with research studies. These challenges are further magnified when obtaining consent from individuals with low literacy levels and who speak languages other than English. In this article we present findings from a qualitative study conducted with Spanish-speaking individuals with low-literacy designed to refine the Agency for Healthcare Research and Quality's Informed Consent and Authorization Toolkit for Minimal Risk Research. Findings from this study indicate that familiarity with providing informed consent and authorization for research or the experience of being a research participant appear to play key roles in an individual's ability to understand the consent and authorization process. While the text of the consent and authorization documents can be simplified using plain language principles, comprehension of several fundamental ideas such as risk and privacy need to be safeguarded with a consent process that confirms comprehension. Recommendations are provided to address the informational needs of individuals with low literacy levels and limited or no experience with research participation.

Depression is a significant problem for ethnic minorities that remains understudied partly due to a lack of strong measures with established psychometric properties. One screening tool, the Patient Health Questionnaire-9 (PHQ-9), which was developed for use in primary care has also gained popularity in research settings. The reliability and validity of the PHQ-9 has been well established among predominantly Caucasian samples, in addition to many minority groups. However, there is little evidence regarding its utility among Hispanic Americans, a large and growing cultural group in the United States. In this study, we investigated the reliability and structural validity of the PHQ-9 in Hispanic American women. A community sample of 479 Latina women from southern California completed the PHQ-9 in their preferred language of English or Spanish. Cronbach’s alphas suggested that there was good internal consistency for both the English- and Spanish-language versions. Structural validity was investigated using multigroup confirmatory factor analysis (CFA). Results support a similar one-factor structure with equivalent response patterns and variances among English- and Spanish-speaking Latinas. These results suggest that the PHQ-9 can be used with confidence in both English and Spanish versions to screen Latinas for depression. PMID:21787063

Purpose The purpose of this study was to describe perception of risk for developing diabetes among foreign-born Spanish-speaking U.S. Latinos. Methods Participants (N=146), recruited at food-pantry distribution events and free clinics, were surveyed using the Risk Perception Survey for Developing Diabetes in Spanish. Type 2 diabetes risk factors measured included: Body Mass Index, physical activity, and Hemoglobin A1C. Results Sample characteristics were mean age 39.5 (±9.9) years old, 58% with less than a high school graduate level education, and 65% with a family income less than $15,000/year. Prevalence of risk factors was 81% overweight or obese, 47% risk for developing diabetes. In univariate logistic regression analyses, 9 of 18 potential variables were significant (pperception of risk. When these 9 variables were entered into a multiple logistic regression model, 5 were significant predictors of perception of risk: history of gestational diabetes, ≥ high school graduate, optimistic bias, worry, and perceived personal disease risk. Conclusions This is the first study using the Risk Perception Survey for Developing Diabetes in Spanish in this population and reveals factors that influence perception of risk for developing diabetes. The results can be used to promote culturally acceptable type 2 diabetes primary prevention strategies and provide a useful comparison to other populations. PMID:27150605

Most questionnaires used for managerial purposes have been developed in Anglo-Saxon countries and then adapted for other cultures. However, this process is controversial. This paper fills the gap for more culturally sensitive assessment instruments in the specific field of human resources while also addressing the methodological issues that scientists and practitioners face in the development of questionnaires. First, we present the development process of a Personal and Motive-based competencies questionnaire targeted to Spanish-speaking countries. Second, we address the validation process by guiding the reader through testing the questionnaire construct validity. We performed two studies: a first study with 274 experts and practitioners of competency development and a definitive study with 482 members of the general public. Our results support a model of nineteen competencies grouped into four higher-order factors. To assure valid construct comparisons we have tested the factorial invariance of gender and work experience. Subsequent analysis have found that women self-rate themselves significantly higher than men on only two of the nineteen competencies, empathy (p < .001) and service orientation (p < .05). The effect of work experience was significant in twelve competencies (p < .001), in which less experienced workers self-rate higher than experienced workers. Finally, we derive theoretical and practical implications.

The United States Latino population is growing at a rapid pace and is set to reach nearly 30% by 2050. The demand for culturally and linguistically competent health care is increasing in lockstep with this growth; however, the supply of doctors with skills and experience suited for this care is lagging. In particular, there is a major shortage of Latino Spanish-speaking physicians, and the gap between demand and supply is widening. The implementation of the Affordable Care Act (ACA) has increased the capacity of the US healthcare system to care for the growing Latino Spanish-speaking population, through health insurance exchanges, increased funding for safety net institutions, and efforts to improve efficiency and coordination of care, particularly with Accountable Care Organizations and the Hospital Readmissions Reduction Program. With these policies in mind, the authors discuss how the value of Latino Spanish-speaking physicians to the healthcare system has increased under the environment of the ACA. In addition, the authors highlight key efforts to increase the supply of this physician population, including the implementation of the Deferred Action for Childhood Arrivals Act, premedical pipeline programs, and academic medicine and medical school education initiatives to increase Latino representation among physicians.

The growing number of Spanish speakers in the United States poses communication challenges for healthcare providers. Language barriers in pediatric acute care have been associated with an increased risk for adverse events, longer hospital stays, and decreased quality of care. In addition, clinicians' usage of interpreter services is inconsistent. In fact, nurses often lack interpreter support during daily bedside care. Nursing staff at a pediatric children's hospital in the southeastern United States identified bedside communication with Spanish-speaking patients and families as a clinical challenge. To address this challenge, a basic communication interface, UTalk version 1.0 (the author is the owner and proprietor), supported by an Apple iPad, was developed by the researcher with input from nursing staff, a certified medical interpreter, and Spanish-speaking community members. A feasibility pilot study of the interface's usability and engagement was conducted on the hospital's pediatric medical-surgical unit through qualitative interviews with nurse-family dyads. Three themes emerged from the data: UTalk-facilitated communication, UTalk needs improvement, and interpreter miscommunication. These findings indicate that a mobile digital device interface is a feasible method for augmenting bedside communication with Spanish-speaking patients and families. These results also may serve as a reference for the development of similar mobile device interfaces. Further research with a larger sample size is needed.

Although many men who have sex with men (MSM) test for HIV at least once in their lifetime, opportunities to improve regular HIV testing, particularly among Hispanic or Latino MSM, is needed. Many mHealth interventions in development, including the ones on HIV testing, have primarily focused on English-speaking white, black, and MSM of other races. To date, no studies have assessed app use, attitudes, and motivations for downloading and sustaining use of mobile apps and preferences with respect to HIV prevention among Spanish-speaking, Hispanic MSM in the United States. The primary aims of this study were to determine what features and functions of smartphone apps do Hispanic, Spanish-speaking MSM believe are associated with downloading apps to their smartphones, (2) what features and functions of smartphone apps are most likely to influence men's sustained use of apps over time, and (3) what features and functions do men prefer in a smartphone app aimed to promote regular testing for HIV. Interviews (N=15) were conducted with a racially diverse group of sexually active, HIV-negative, Spanish-speaking, Hispanic MSM in Miami, Florida. Interviews were digitally recorded, transcribed verbatim, translated back to English, and de-identified for analysis. A constant-comparison method (ie, grounded theory coding) was employed to examine themes that emerged from the interviews. Personal interest was the primary reason associated with whether men downloaded an app. Keeping personal information secure, cost, influence by peers and posted reviews, ease of use, and functionality affected whether they downloaded and used the app over time. Men also reported that entertainment value and frequency of updates influenced whether they kept and continued to use an app over time. There were 4 reasons why participants chose to delete an app-dislike, lack of use, cost, and lack of memory or space. Participants also shared their preferences for an app to encourage regular HIV testing by

Addenbrooke's Cognitive Examination-Revised is a brief test battery for the detection and classification of mild cognitive impairment and dementia. The aims were to investigate the influence of age and education on the Spanish version of the ACE-R and to propose normative data for the Spanish speaking population. Three hundred thirty-four normal healthy volunteers were included in the study. They were classified in three age groups (48-64, 65-75, and 75-89 years of age) and four educational level groups (≤3; 4-8; 9-12, and ≥13 years of education). They were assessed with the version of ACE-R validated in Argentina with some modifications in order to adapt it to the Spanish population. Significant differences were obtained between all age groups in Total ACE-R, Memory, Fluency, and Language indexes. Differences were observed among the 48-64 and 76-89 age groups in the Attention-Orientation and Visuospatial indexes. Regarding education, significant difference between ≤3 years of education and the remaining groups were obtained in Total ACE-R and in all the indexes. Additionally, the group of 4-8 years of education performed significantly worse than the 9-12 and ≥13 groups in Total, Memory, Fluency, and Language indexes. Adjusted scores by education were obtained and percentiles for each age group were calculated. The results show that both age and education have an important effect on ACE-R performance. Consequently, age and education should be taken into account when interpreting results in ACE-R to improve diagnostic accuracy. © The Author 2016. Published by Oxford University Press.

Coastal habitats are vulnerable to storms, and with increasing urbanization, sea level rise, and storm frequency, some urban populations are at risk. This study examined perceptions of respondents in coastal and central New Jersey to Superstorm Sandy , including: 1) concerns about ecological resources and effects (open-ended question), 2) information sources for ecology of the coast (open-ended), and 3) ratings of a list of ecological services as a function of demographics, location (coastal, central Jersey), stressor level (power outages, high winds, flooding) and recreational rates. "Wildlife" and "fish" were the ecological concerns mentioned most often, while beaches and dunes were most often mentioned for environmental concerns. Television, radio, and web/internet were sources trusted for ecological information. The data indicate 1) stressor level was a better predictor of ratings of ecological services than geographical location, but days engaged in recreation contributed the most to variations in ratings, 2) ecological services were rated the highest by respondents with the highest stressor levels, and by those from the coast, compared to others, 3) Caucasians rated ecological services higher than all others, and 4) recreational rates were highest for coastal respondents, and ratings for ecological services increased with recreational rates. Only 20 % of respondents listed specific ecological services as one of their three most important environmental concerns. These data will be useful for increasing preparedness, enhancing educational strategies for shore protection, and providing managers and public policy makers with data essential to developing resiliency strategies.

To assess the health literacy and numeracy skills of Spanish-speaking parents of young children and to validate a new Spanish language health literacy assessment for parents, the Spanish Parental Health Literacy Activities Test (PHLAT Spanish). Cross-sectional study of Spanish-speaking caregivers of young children (validated tests of health literacy (S-TOFHLA) and numeracy (WRAT-3 Arithmetic). Psychometric analysis was used to examine item characteristics of the PHLAT-10 Spanish, to assess its correlation with sociodemographics and performance on literacy/numeracy assessments, and to generate a shorter 8-item scale (PHLAT-8). Of 176 caregivers, 77% had adequate health literacy (S-TOFHLA), whereas only 0.6% had 9th grade or greater numeracy skills. Mean PHLAT-10 score was 41.6% (SD 21.1). Fewer than one-half (45.5%) were able to read a liquid antibiotic prescription label and demonstrate how much medication to administer within an oral syringe. Less than one-third (31.8%) were able to interpret a food label to determine whether it met WIC (Special supplemental nutrition program for Women, Infants, and Children) guidelines. Greater PHLAT-10 score was associated with greater years of education (r = 0.49), S-TOFHLA (r = 0.53), and WRAT-3 (r = 0.55) scores (P Spanish-speaking parents have difficulty performing health-related literacy and numeracy tasks. The Spanish PHLAT demonstrates good psychometric characteristics and may be useful for identifying parents who would benefit from receiving low-literacy child health information.

Hispanics are the largest growing population in the United States, and their use of prescription medications can be influenced by the education and counseling they receive from pharmacists. However, little is known about pharmacists' communication with patients who speak Spanish or factors that can influence such communication. The objective of the study was to develop and validate an instrument to measure pharmacists' self-efficacy in communicating with Spanish-speaking patients. An initial pool of 15 items developed from previous research and suggestions from communication experts and practicing pharmacists was subjected to cognitive interviewing. Nine retained items were administered to 1022 licensed pharmacists by mail survey. Summary statistics and exploratory factor analysis (EFA) were conducted. Retained factors were determined by the examination of eigenvalues and scree test results. Cronbach's alpha coefficients were calculated to assess internal consistency. A total of 540 community pharmacists completed the survey. Item means ranged from 2.93±1.47 to 1.58±0.88 based on a 5-point scale (1: not at all confident to 5: extremely confident). EFA resulted in a 2-factor solution, accounting for 71% of the variance. The 2 factors consisted of health and drug information (alpha=0.92) and opening the encounter (alpha=0.75). The alpha for the overall scale was 0.88. The results provide evidence to support the reliability and validity of an instrument to measure pharmacists' self-efficacy beliefs about communicating with Spanish-speaking patients in community practice. Practitioners and researchers may use this instrument to inform pharmacy education, pharmacy practice improvement, and research efforts around communicating with Spanish-speaking clients.

Full Text Available We propose a methodological approach to identify a multifunctional green infrastructure (GI on the basis of four values (conservation value, natural value, recreation value and anthropic heritage that represent many functions (biodiversity conservation, supply of ecosystem services, recreation, identity building performed by the landscape. By taking the Italian region of Sardinia as a case study, we argue that the methodology can support the making of landscape plans as understood in the European Landscape Convention. Moreover, we propose and implement a methodology to identify ecological corridors (ECs connecting Natura 2000 sites (N2Ss, based on the prioritization of functional land patches related to their suitability to ecosystem services delivery, paying particular attention to biodiversity maintenance and enhancement, and taking Sardinia as spatial regional context. The methodology consists of two steps: (i identifying the most suitable patches to be included in ECs on the basis of their connectivity, that is, on their negative attitude towards contributing to landscape fragmentation; (ii assessing, through a discrete-choice-model, the suitability of these ECs to be included in a regional GI, starting from the territorial taxonomy based on biodiversity characteristics related to N2Ss, habitat suitability, and recreational and landscape potentials.

The Personal Patient Profile-Prostate (P3P), a web-based decision aid, was demonstrated to reduce decisional conflict in English-speaking men with localized prostate cancer early after initial diagnosis. The purpose of this study was to explore and enhance usability and cultural appropriateness of a Spanish P3P by Latino men with a diagnosis of prostate cancer. P3P was translated to Spanish and back-translated by three native Spanish-speaking translators working independently. Spanish-speaking Latino men with a diagnosis of localized prostate cancer, who had made treatment decisions in the past 24 months, were recruited from two urban clinical care sites. Individual cognitive interviews were conducted by two bilingual research assistants as each participant used the Spanish P3P. Notes of user behavior, feedback, and answers to direct questions about comprehension, usability and perceived usefulness were analyzed and categorized. Seven participants with a range of education levels identified 25 unique usability issues in navigation, content comprehension and completeness, sociocultural appropriateness, and methodology. Revisions were prioritized to refine the usability and cultural and linguistic appropriateness of the decision aid. Usability issues were discovered that are potential barriers to effective decision support. Successful use of decision aids requires adaptation and testing beyond translation. Our findings led to revisions further refining the usability and linguistic and cultural appropriateness of Spanish P3P.
Full Text Available The purpose of this study is the adaptation and validation of the "Survey Work-Home Interaction - NijmeGen" (SWING developed by Geurts and colleagues to Spanish speaking countries (SWING-SSC. In order to analyze the questionnaire's psychometnc properties, confirmatory factor analysis (CFA was carried out with a sample of 203 employees from various Spanish-speaking countries. Criterion related validity was tested by examining correlations between the SWING-SSC, and the theoretically relevant variables: health, role conflict, role clarity and supervisor support. Finally, reliability was tested analyzing the internal consistency of the scales. The analyses carried out indicate that SWING-SSC has good psychometric properties. In addition, the present results support the relation of the construct with health, role conflict, role clarity, and supervisor support. This study offers evidence for a sound work-life balance measure that contributes to encourage adequate conditions in the workplace, to reduce the conflict between the two spheres of professional and personal life, and to enhance positive relationships.

Bipolar disorder is commonly misdiagnosed, perhaps more so in Latin American and Spanish-speaking populations than in the United States. The Bipolar Spectrum Diagnostic Scale (BSDS) is a 19-item screening instrument designed to assist in screening for all types of bipolar disorder. The authors investigated the sensitivity of a Spanish-language version of the BSDS in a cohort of 65 outpatients with a diagnosis of bipolar disorder, based on a semi-structured interview and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. To determine specificity, we assessed a control group of 36 outpatients with diagnosis of unipolar major depressive disorder. The overall sensitivity of the BSDS Spanish version with bipolar disorders types I, II, and NOS was 0.70, which was slightly lower than the sensitivity in the study using the English version of the BSDS (0.76). The specificity was 0.89. When the threshold was decreased from 13 to 12, the sensitivity of the Spanish BSDS increased to 0.76 and specificity dropped to 0.81. The Spanish version of the BSDS is promising as a screening instrument in Spanish-speaking populations. Copyright 2010 Elsevier Inc. All rights reserved.

We investigated the extent to which implementing language assistance programming through contracting with community-based organizations improved the accessibility of mental health care under Medi-Cal (California’s Medicaid program) for Spanish-speaking persons with limited English proficiency, and whether it reduced language-based treatment access disparities. Methods. Using a time series nonequivalent control group design, we studied county-level penetration of language assistance programming over 10 years (1997–2006) for Spanish-speaking persons with limited English proficiency covered under Medi-Cal. We used linear regression with county fixed effects to control for ongoing trends and other influences. Results. When county mental health plans contracted with community-based organizations, those implementing language assistance programming increased penetration rates of Spanish-language mental health services under Medi-Cal more than other plans (0.28 percentage points, a 25% increase on average; P language-related disparities. Conclusions. Mental health treatment programs operated by community-based organizations may have moderately improved access after implementing required language assistance programming, but the programming did not reduce entrenched disparities in the accessibility of mental health services.

This study examined the effectiveness of teaching low-income Spanish-speaking caregivers of young children with language impairment a naturalistic language intervention, EMT en Español. A single-case, multiple-baseline, across-behaviors design replicated across 3 caregiver-child dyads was used to examine the effects of teaching core EMT en Español strategies. The training program utilized the Teach-Model-Coach-Review instructional approach to teach strategies to support children's language development in Spanish. All sessions were at home and in Spanish. Caregivers increased their use of matched turns, target talk, expansions, and a communication elicitation procedure following training on each specific skill. Additionally, caregivers generalized increased use of matched turns and target talk to an untrained activity during the intervention period and maintained their behavior 1 month after completing intervention. Two of 3 caregivers generalized their use of expansions, and 1 caregiver generalized her use of a communication elicitation procedure. Modest effects on the child's number of different words were observed for 2 of the 3 target children over the course of the intervention sessions. All 3 children demonstrated increases in total spontaneous words. Spanish-speaking caregivers were able to implement naturalistic language teaching strategies with their young children with language impairment in a relatively short-term intervention.

Introduction Advance care planning (ACP) is a process that allows patients to identify their goals for medical care. Traditionally, ACP has focused on completing advance directives; however, we have expanded the ACP paradigm to also prepare patients to communicate their wishes and make informed decisions. To this end, we created an ACP website called PREPARE (http://www.prepareforyourcare.org) to prepare diverse English-speaking and Spanish-speaking older adults for medical decision-making. Here, we describe the study protocol for a randomised controlled efficacy trial of PREPARE in a safety-net setting. The goal is to determine the efficacy of PREPARE to engage diverse English-speaking and Spanish-speaking older adults in a full spectrum of ACP behaviours. Methods and analysis We include English-speaking and Spanish-speaking adults from an urban public hospital who are ≥55 years old, have ≥2 chronic medical conditions and have seen a primary care physician ≥2 times in the last year. Participants are randomised to the PREPARE intervention (review PREPARE and an easy-to-read advance directive) or the control arm (only the easy-to-read advance directive). The primary outcome is documentation of an advance directive and/or ACP discussion. Secondary outcomes include ACP behaviour change processes measured with validated surveys (eg, self-efficacy, readiness) and a broad range of ACP actions (eg, choosing a surrogate, identifying goals for care, discussing ACP with clinicians and/or surrogates). Using blinded outcome ascertainment, outcomes will be measured at 1 week and at 3, 6 and 12 months, and compared between study arms using mixed-effects logistic regression and mixed-effects linear, Poisson or negative binomial regression. Ethics and dissemination This study has been approved by the appropriate Institutional Review Boards and is guided by input from patient and clinical advisory boards and a data safety monitoring board. The results of this study will

Objectives To determine the effectiveness of the Contra Caries Oral Health Education Program (CCOHEP) for improving low-income, Spanish-speaking parents’ oral health knowledge and behaviors for their young children. Mexican American children in the United States suffer disproportionately high prevalence and severity of early childhood caries, yet few evaluated, theory-based behavioral interventions exist for this population. CCOHEP is a theory-based curriculum consisting of four 2-hour interactive classes designed for and by Spanish speakers and led by designated community health educators (promotoras). Topics included children’s oral hygiene, caries etiology, dental procedures, nutrition, child behavior management and parent skill-building activities. Methods Low-income Spanish-speaking parents/caregivers of children aged 0–5 years were recruited through community services in an agricultural city in California. Survey questions from the Oral Health Basic Research Facts Questionnaire measuring oral health related behaviors and knowledge were verbally administered before, immediately after, and 3 months after attendance at CCOHEP. Five questions measured aspects of parental tooth brushing for their children (frequency, using fluoridated toothpaste, brushing before bed, not drinking or eating after nighttime brushing, adult assistance), three questions measured other oral health behaviors, and 16 questions measured oral health-related knowledge. Analyses of within-person changes between pre- and posttests, and again between post-test and three month follow up consisted of McNemar’s test for binary outcomes and sign tests for ordinal outcomes. Results Overall, 105 caregivers participated in CCOHEP (n= 105 pretest, n=95 posttest, n=79 second posttest). At baseline, all parents self-reported doing at least one aspect of toothbrushing correctly, but only 13% reported performing all five aspects according to professional guidelines. At posttest, 44% of parents

The utility of the Spanish WAIS-III was investigated by examining its reliability and validity among 100 Spanish-speaking participants. Results indicated that the internal consistency of the subtests was satisfactory, but inadequate for Letter Number Sequencing. Criterion validity was adequate. Convergent and discriminant validity results were generally similar to the North American normative sample. Paired sample t-tests suggested that the WAIS-III may underestimate ability when compared to the criterion measures that were utilized to assess validity. This study provides support for the use of the Spanish WAIS-III in urban Hispanic populations, but also suggests that caution be used when administering specific subtests, due to the nature of the Latin America alphabet and potential test bias.

There is a multiplicity of journals originating in Spain and the Spanish-speaking countries of Latin America and the Caribbean (SSLAC) in the health sciences of relevance to the fields of epidemiology and public health. While the subject matter of epidemiology in Spain shares many features with its neighbours in Western Europe, many aspects of epidemiology in Latin America are particular to that region. There are also distinctive theoretical and philosophical approaches to the study of epidemiology and public health arising from traditions such as the Latin American social medicine movement, of which there may be limited awareness. A number of online bibliographic databases are available which focus primarily on health sciences literature arising in Spain and Latin America, the most prominent being Literatura Latinoamericana en Ciencias de la Salud (LILACS) and LATINDEX. Some such as LILACS also extensively index grey literature. As well as in Spanish, interfaces are provided in English and Portuguese. Abstracts of articles may also be provided in English with an increasing number of journals beginning to publish entire articles written in English. Free full text articles are becoming accessible, one of the most comprehensive sources being the Scientific Electronic Library Online (SciELO). There is thus an extensive range of literature originating in Spain and SSLAC freely identifiable and often accessible online, and with the potential to provide useful inputs to the study of epidemiology and public health provided that any reluctance to explore these resources can be overcome. In this article we provide an introduction to such resources.

We describe an innovative community-centered participatory design approach, Consumer-centered Participatory Design (C2PD), and the results of applying C2PD to design and develop a web-based fall prevention system. We conducted focus groups and design sessions with English- and Spanish-speaking community-dwelling older adults. Focus group data were summarized and used to inform the context of the design sessions. Descriptive content analysis methods were used to develop categorical descriptions of design session informant's needs related to information technology. The C2PD approach enabled the assessment and identification of informant's needs of health information technology (HIT) that informed the development of a falls prevention system. We learned that our informants needed a system that provides variation in functions/content; differentiates between actionable/non-actionable information/structures; and contains sensory cues that support wide-ranging and complex tasks in a varied, simple, and clear interface to facilitate self-management. The C2PD approach provides community-based organizations, academic researchers, and commercial entities with a systematic theoretically informed approach to develop HIT innovations. Our community-centered participatory design approach focuses on consumer's technology needs while taking into account core public health functions.

Understanding attitudes toward science and measuring them remain two major challenges for science teaching. This article reviews the concept of attitudes toward science and their measurement. It subsequently analyzes the psychometric properties of the Test of Science-Related Attitudes (TOSRA), such as its construct validity, its discriminant and concurrent validity, and its reliability. The evidence presented suggests that TOSRA, in its Spanish-adapted version, has adequate construct validity regarding its theoretical referents, as well as good indexes of reliability. In addition, it determines the attitudes toward science of secondary school students in Santiago de Chile (n = 664) and analyzes the sex variable as a differentiating factor in such attitudes. The analysis by sex revealed low-relevance gender difference. The results are contrasted with those obtained in English-speaking countries. This TOSRA sample showed good psychometric parameters for measuring and evaluating attitudes toward science, which can be used in classrooms of Spanish-speaking countries or with immigrant populations with limited English proficiency.

This study describes the perceptions of brain health among older Spanish-speaking Mexican Americans who reside in colonia areas of the Lower Rio Grande Valley of Texas. In 2007, 33 Mexican American older adults (9 men and 24 women) were recruited by promotoras (community health workers) from clusters of colonias in Hidalgo County to participate in focus group discussions conducted in Spanish. After participants completed a 19-item questionnaire (in Spanish), a bilingual and bicultural researcher from the community, trained as a moderator, conducted 4 focus groups using a semistructured interview guide, culturally modified with the assistance of promotoras. All discussions were audio recorded; audio recordings were transcribed verbatim in Spanish and then translated into English. Analyses were conducted in English. Almost 85% had less than a high school education and 100% reported a household income less than $20,000/year. Groups attached cultural meaning to aging well. The idea of "staying straight in the mind" resonated as a depiction of brain health. Participants also mentioned the types of activities they could do to stay "right in the mind." Particular attention must be focused on development of programs that provide satisfying culturally appropriate activities for older participants and the delivery of health messages that take into consideration culture and language.

This study examines the validity of a Spanish-language dietary behaviors self-report questionnaire (LDBQ) for Latinos with diabetes. The sample (n = 252) was Spanish-speaking, female (77%), middle-aged (mean age = 55 years), low-education (56% internal consistency analysis; and correlation analysis using baseline and change scores for: LDBQ, three day 24-hour dietary recall nutrient mean, and clinical measures. Cronbach’s alphas were moderate. Four factors were identified at both time points. Significant baseline correlations (r) were found for LDBQ total scores, factor scores and: caloric intake (r = −.29 to −.34); total dietary fiber (r = .19); sodium (r = −.24 to −.30); percent calories from total fat (r = −.16); fat subtypes (r = −.16 to .15); and percent calories from protein (r = .17). Twelvemonth data produced a similar pattern. T-tests of LDBQ change scores showed significantly greater change in dietary behaviors for the intervention group than for the control group, t(135) = −4.17, p < .01. LDBQ change scores correlated significantly with mean 24-hour nutrient intake and a subset of clinical measures, but were not associated with clinical change scores (except HDL). The LDBQ is a useful tool to assess and target behaviors for change and assess intervention effects. PMID:21443994

This article discusses two investigations which explored the bilingual language development outcomes of comparable groups of low-income, Spanish-speaking, Mexican American children who either did or did not attended a bilingual (Spanish/English) preschool. Study 1 is a replication of a study by Rodríguez, Díaz, Duran, and Espinosa, involving a new sample of 26 children who attended bilingual preschool for one year and 20 control children who remained at home. Study 2 represents a 1-year, longitudinal follow-up of Rodríguez et al.'s, sample of children during and after the children spent another year at home or in the preschool. In both investigations, standardized, objective measures of three components of children's language proficiency (productive language, receptive language, and language complexity) in English and Spanish were obtained at the beginning and end of the academic year. Contrary to fears that have been expressed by some that early exposure to English would lead to children's native language loss, the results of both studies offered no evidence of Spanish proficiency loss for children attending bilingual preschool. Children who attended bilingual preschool, compared to those who remained at home, showed significant and parallel gains in Spanish language development as well as significant and greater increases in English language proficiency over time. Results are discussed in terms of the need for more systematic research to be conducted in this area to inform policy and practice in the early education and development of language-minority children.

As part of a larger implementation trial for cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD) in a community health center, we used formative evaluation to assess relations between iterative cultural adaption (for Spanish-speaking clients) and implementation outcomes (appropriateness and acceptability) for CPT. Qualitative data for the current study were gathered through multiple sources (providers: N = 6; clients: N = 22), including CPT therapy sessions, provider fieldnotes, weekly consultation team meetings, and researcher fieldnotes. Findings from conventional and directed content analysis of the data informed refinements to the CPT manual. Data-driven refinements included adaptations related to cultural context (i.e., language, regional variation in wording), urban context (e.g., crime/violence), and literacy level. Qualitative findings suggest improved appropriateness and acceptability of CPT for Spanish-speaking clients. Our study reinforces the need for dual application of cultural adaptation and implementation science to address the PTSD treatment needs of Spanish-speaking clients. © 2016 Wiley Periodicals, Inc.
Malouf’s ecological concerns and interest in the natural world and their relationship with the cultural can be traced in most of his works, both in prose and poetry. Space and place such as the wilderness and the garden, the steppe and the Roman Empire, the Australian bush and the city are fundamental elements in Malouf’s delineation of individual, social, political and cultural relationships with the land. This article focuses on “Jacko’s Reach” (Malouf 2000), where, under the label of progr...

Physical activity (PA) has documented health benefits, but older Latinos are less likely to engage in leisure time PA than older non-Latino whites. Dance holds promise as a culturally appropriate form of PA that challenges individuals physically and cognitively. This paper describes a randomized controlled trial that will test the efficacy of BAILAMOS©, a 4-month Latin dance program followed by a 4-month maintenance program, for improving lifestyle PA and health outcomes. Older adults (n = 332), aged 55+, Latino/Hispanic, Spanish speaking, with low PA levels, and at risk for disability will be randomized to one of two programs, a dance program or health education control group. BAILAMOS© is a 4-month program that meets two times per week for one hour per session. Dance sessions focus on instruction, including four styles of dance, and couples dancing. Bi-monthly “Fiestas de Baile” (dance parties) are also included, in which participants dance and practice what they have learned.. Monthly 1-hour discussion sessions utilize a Social Cognitive framework and focus on knowledge, social support, and self-efficacy to increase lifestyle PA. The health education control group will meet one time per week for two hours per session. Primary outcomes including PA changes and secondary outcomes including self-efficacy, physical function, cognitive function, and disability will be assessed at baseline, 4, and 8 months. It is hypothesized that PA, self-efficacy, physical function, cognitive function, and functional limitations and disability scores will be significantly better in the BAILAMOS© group at 4 and 8 months compared to the control group.

Most studies done with Hispanics illustrate their preference for self-management practices; therefore, examining the factors driving patients to seek medical care for pain management will help elucidate what patients want and need from their doctors for pain management. The aim of the present study was to obtain patients' perspectives and enhance our understanding of the cultural beliefs influencing pain management decisions of foreign-born Spanish-speaking Hispanics with low acculturation. Twenty-four individuals (17 females and 7 males) with self-reported chronic pain completed the study. Participants attended a focus group and shared about pain management practices and their experiences with medical care for pain management. Descriptive data on pain and mood variables were collected to examine how this population compares with the norms reported in the pain literature for Hispanics. Participants reported a preference for pain self-management and noninvasive medical treatments and expressed negative attitudes toward pain medications, although wanting the option of pain medications as a "last resort." Satisfaction with medical care for pain was highly influenced by the participants' expectations and preference for personal, warm, and friendly interactions. Our findings are consistent with previous reports on Hispanics' preference for self-care practices. Perhaps foreign-born Hispanics may rely on self-care practices and delay medical attention for pain management because of their unfamiliarity with the US health care system. Other potential explanations for a reliance on self-care for pain management involve patients having a limited understanding of or access to effective treatment options for chronic pain and negative experiences with US medical providers. © 2016 American Academy of Pain Medicine.

This article describes the adaptation and initial validation of the Cancer Health Literacy Test (CHLT) for Spanish speakers. A cross-sectional field test of the Spanish version of the CHLT (CHLT-30-DKspa) was conducted among healthy Latinos in Louisiana. Diagonally weighted least squares was used to confirm the factor structure. Item response analysis using 2-parameter logistic estimates was used to identify questions that may require modification to avoid bias. Cronbach's alpha coefficients estimated scale internal consistency reliability. Analysis of variance was used to test for significant differences in CHLT-30-DKspa scores by gender, origin, age and education. The mean CHLT-30-DKspa score (N = 400) was 17.13 (range = 0-30, SD = 6.65). Results confirmed a unidimensional structure, χ(2)(405) = 461.55, p = .027, comparative fit index = .993, Tucker-Lewis index = .992, root mean square error of approximation = .0180. Cronbach's alpha was .88. Items Q1-High Calorie and Q15-Tumor Spread had the lowest item-scale correlations (.148 and .288, respectively) and standardized factor loadings (.152 and .302, respectively). Items Q19-Smoking Risk, Q8-Palliative Care, and Q1-High Calorie had the highest item difficulty parameters (difficulty = 1.12, 1.21, and 2.40, respectively). Results generally support the applicability of the CHLT-30-DKspa for healthy Spanish-speaking populations, with the exception of 4 items that need to be deleted or revised and further studied: Q1, Q8, Q15, and Q19.

Colorectal cancer (CRC) is a leading cause of death among Hispanics in the United States. Despite the benefits of CRC screening, many Hispanics are not being screened. Using a combined methodology of focus groups and discrete choice experiment (DCE) surveys, the objectives for this research were as follows: (1) to improve understanding of preferences regarding potential CRC screening program characteristics, and (2) to improve understanding of the barriers and facilitators around CRC screening with the Hispanic, immigrant community in North Carolina. Four gender-stratified focus groups were conducted and DCE surveys were administered to 38 Spanish-speaking individuals across four counties in North Carolina. In-depth content analysis was used to examine the focus group data; descriptive analyses and mean attribute importance scores for cost of screening and follow-up care, travel time, and test options were calculated from DCE data. Data analyses showed that this population has a strong interest in CRC screening but experience barriers such as lack of access to resources, cost uncertainty, and stigma. Some of these barriers are unique to their cultural experiences in the United States, such as an expressed lack of tailored CRC information. Based on the DCE, cost variables were more important than testing options or travel time. This study suggests that Hispanics may have a general awareness of and interest in CRC screening, but multiple barriers prevent them from getting screened. Special attention should be given to designing culturally and linguistically appropriate programs to improve access to healthcare resources, insurance, and associated costs among Hispanics.

The purpose of this study was to compare how English language learners (ELLs) and monolingual English speakers solved multiple-choice items administered with and without a new form of testing accommodation---vignette illustration (VI). By incorporating theories from second language acquisition, bilingualism, and sociolinguistics, this study was able to gain more accurate and comprehensive input into the ways students interacted with items. This mixed methods study used verbal protocols to elicit the thinking processes of thirty-six native Spanish-speaking English language learners (ELLs), and 36 native-English speaking non-ELLs when solving multiple-choice science items. Results from both qualitative and quantitative analyses show that ELLs used a wider variety of actions oriented to making sense of the items than non-ELLs. In contrast, non-ELLs used more problem solving strategies than ELLs. There were no statistically significant differences in student performance based on the interaction of presence of illustration and linguistic status or the main effect of presence of illustration. However, there were significant differences based on the main effect of linguistic status. An interaction between the characteristics of the students, the items, and the illustrations indicates considerable heterogeneity in the ways in which students from both linguistic groups think about and respond to science test items. The results of this study speak to the need for more research involving ELLs in the process of test development to create test items that do not require ELLs to carry out significantly more actions to make sense of the item than monolingual students.

This study examined young, preschool children's oral health-related quality of life (OHRQoL) among a community-based cohort of English and Spanish-speaking parent-child dyads in North Carolina, and sought to quantify the association of parent/caregiver characteristics, including spoken language, with OHRQoL impacts. Data from structured interviews with 1,111 parents of children aged 6-23 months enrolled in the Zero-Out Early Childhood Caries study in 2010-2012 were used. OHRQoL was measured using the overall score (range: 0-52) of the Early Childhood Oral Health Impact Scale (ECOHIS). We examined associations with parents' sociodemographic characteristics, spoken language, self-reported oral and general health, oral health knowledge, children's dental attendance, and dental care needs. Analyses included descriptive, bivariate, and multivariate methods based upon zero-inflated negative binomial regression. To determine differences between English and Spanish speakers, language-stratified model estimates were contrasted using homogeneity χ 2 tests. The mean overall ECOHIS score was 3.9 [95% confidence interval (CI) = 3.6-4.2]; 4.7 among English-speakers and 1.5 among Spanish speakers. In multivariate analyses, caregivers' education showed a positive association with OHRQoL impacts among Spanish speakers [prevalence ratio (PR) = 1.12 (95% CI = 1.03-1.22), for every added year of schooling], whereas caregivers' fair/poor oral health showed a positive association among English speakers (PR = 1.20; 95% CI = 1.02-1.41). The overall severity of ECOHIS impacts was low among this population-based sample of young, preschool children, and substantially lower among Spanish versus English speakers. Further studies are warranted to identify sources of these differences in - actual or reported - OHRQoL impacts. © 2016 American Association of Public Health Dentistry.

Information and communications technologies, like social media, have the potential to reduce some barriers in disease prevention and control in the Americas. National health authorities can use these technologies to provide access to reliable and quality health information. A study was conducted to analyze availability of information about the leading causes of death on social media channels of national health authorities in 18 Spanish-speaking Latin American and Caribbean countries. We gathered data of national health authorities's institutional presence in social media. Exploratory-descriptive research was useful for analysis and interpretation of the data collected. An analysis was carried out for 6 months, from April 1 to September 30, 2015. Sixteen of the 18 countries studied have institutional presences on social media. National health authorities have a presence in an average of almost three platforms (2.8%). An average of 1% of the populations with Internet access across the 18 countries in this study follows national health authorities on social media (approximately, an average of 0.3% of the total population of the countries under study). On average, information on 3.2 of the 10 leading causes of death was posted on the national health authorities' Facebook pages, and information on 2.9 of the 10 leading causes of death was posted on their Twitter profiles. Additionally, regarding public health expenditures and the possibility of retrieving information on the leading causes of death, an apparent negative correlation exists in the case of Facebook, r(13) = -.54, P = .03 and a weak negative correlation in the case of Twitter, r(14) = -.26, P = .31, for the countries with presences in those networks. National health authorities can improve their role in participating in conversations on social media regarding the leading causes of death affecting their countries. Taking into account Internet accessibility levels in the countries under study

Patients' and family members' experiences of hospital care are important indicators of quality. "Black, Asian, and Hispanic patients are more at risk than White patients for decreased satisfaction with care." In addition, of any of these groups, Hispanic patients were most likely to report a lack of patient-centered care. In the intensive care setting, (ICU) previous research has indicated that the needs and satisfaction of family members of neurological ICU patients are different from those of family members of other types of ICU patients. The purpose of this study was to determine if there were any differences between English-speaking and Spanish-speaking family members of patients in a neurological ICU. This study was a single center prospective study conducted over a 10-month period from April 2013 to February 2014 in the 18-bed neuroscience ICU of a large, urban, academic medical center. The Family Satisfaction with ICU (FS-ICU) questionnaire was used; it provides an overall score and has two factors: satisfaction with care and satisfaction with decision-making. There was no statistical significance between the two groups in overall satisfaction or in satisfaction with care, however Spanish-speakers (n=22) were significantly less satisfied (p=.04) than English-speakers (n=50) with decision-making. There were three other discreet variables in which Spanish-speakers were also less satisfied: (a) management of patients' pain (OR 3.16, 95% CI [1.12, 8.9]) (b) management of patients' breathlessness (OR 3.5, 95% CI [1.23, 9.96]) as well as (c) ease of getting information (OR 3.25, 95% CI [1.09, 9.64]). Using a standardized survey it was found that Spanish-speakers were statistically less satisfied with decision-making than English-speakers. Additionally, Spanish-speakers were statistically less satisfied with management of patients' pain and breathlessness and ease of getting information. Based on these findings, increased vigilance is recommended regarding decision

Objectives To evaluate the feasibility and efficacy of a handheld personal digital assistant (PDA)-based supplement for maternal Problem-Solving Skills Training (PSST) and to explore Spanish-speaking mothers’ experiences with it. Methods Mothers (n = 197) of children with newly diagnosed cancer were randomized to traditional PSST or PSST + PDA 8-week programs. Participants completed the Social Problem-Solving Inventory-Revised, Beck Depression Inventory-II, Profile of Mood States, and Impact of Event Scale-Revised pre-, post-treatment, and 3 months after completion of the intervention. Mothers also rated optimism, logic, and confidence in the intervention and technology. Results Both groups demonstrated significant positive change over time on all psychosocial measures. No between-group differences emerged. Despite technological “glitches,” mothers expressed moderately high optimism, appreciation for logic, and confidence in both interventions and rated the PDA-based program favorably. Technology appealed to all Spanish-speaking mothers, with younger mothers showing greater proficiency. Conclusions Well-designed, supported technology holds promise for enhancing psychological interventions. PMID:19091804
Full Text Available Malouf’s ecological concerns and interest in the natural world and their relationship with the cultural can be traced in most of his works, both in prose and poetry. Space and place such as the wilderness and the garden, the steppe and the Roman Empire, the Australian bush and the city are fundamental elements in Malouf’s delineation of individual, social, political and cultural relationships with the land. This article focuses on “Jacko’s Reach” (Malouf 2000, where, under the label of progress, globalisation is enforcing the development of a local natural place. Jacko’s Reach, “our last pocket of scrub”, will be destroyed by “mechanical shovels and cranes”, to build “a new shopping mall” (93, deceptively advertised as a necessity for the benefit of the community. The narratorial voice on the surface describes a usual event, the building of a new shopping centre, and at the same time criticises the destruction of the natural world for the sake of progress, which leads to the annihilation of wilderness in order to domesticate and acculturate it. This article focuses in particular on Malouf’s narrative strategies, which, more relevantly, emphasise the mythological power of the imagined or remembered place as a form of resistance to the devastation of the natural environment. In “the dimension of the symbolic” (99, through memory, imagination, creativity and dream, the total erasure of wilderness – in both the natural world and ourselves – cannot be fully achieved. Constantly re-imagined and re-configured in our memory, it will be forever “pushing up under the concrete” (99, and “in our head” (100, in a profound visionary and creative interconnectedness between the natural world and the human being.
Full Text Available As part of a pilot study aimed at the transcultural analysis of environmental concern and its relationship with ecological behavior, a questionnaire assessing these was developed in Spain, and tested in Spain and in Chile. Chilean (n=88 and Spanish (n=149 students filled out the questionnaire. The results were analysed according to the model of multidimensional conceptualisation of concern for the environment manifested in 4 types of attitude: apathetic, anthropocentric, connected and emotional affinity (Amérigo et al., 2012. Results differed between the two groups, and cultural and psychosocial variables appear to play a significant role in this. This suggest that it is important to have instruments that facilitate environmental studies in the Chilean context, and to take contextual factors (such as the exacerbation of the country's environmental crisis and citizens' concern about the situation into account in such studies. Transcultural studies are key to deepening our understanding of the subject at the worldwide level.

To compare the incidence of weight concerns and food habits between two ethnically different groups of adolescent girls residing in two distinct ecological settings: the plains of Kolkata and the mountains of Sikkim. Two separate cross-sectional studies were conducted within a period of five years in urban hilly areas of Sikkim and the city of Kolkata, India. A total of 506 girls aged 14-19 years were selected from the study areas of Sikkim (n=224) and Kolkata (n=282). Girls were interviewed for weight concerns and food habits along with socio-demographic characteristics. Weight concerns were assessed with four variables such as, perceptions about own body weight, felt dissatisfied with own body weight, urge for dieting and use of weight reduction diet. Food habits included consumption of major foods during the past one week. Bivariate analyses showed that Kolkata girls perceived themselves as overweight, remained dissatisfied with body weight, expressed perceived need for dieting and followed weight reduction diet more compared to the girls of Sikkim. Food habits indicated that all Sikkimese girls preferred to consume cereals regularly, while Kolkata girls consumed vegetables, pulses, fish, fruits, bread and butter and fried foods more than Sikkimese girls. Multivariate analyses showed that place of residence was significantly (pfood habits of girls. Diversity in culture, ethnicity and socio-economic standard perhaps develop the disparity in food habits and weight concerns between girls of urban hilly areas of Sikkim and the city of Kolkata.

This study presents part of a long-term research report on the impact of emissions from a nitrogen plant upon soil zoocenoses and appraises the ecological functions of ants and earthworms. Ants (Formica polyctena) were almost the only organisms in the study area which revealed higher activity and ever increasing number of nests on the area of the strongest impact of industrial emissions. The mean increase over a 3 year period amounted to 3 nests per 10 ha per year. It was found that not only more microorganisms occurred in ant nests than in the soil adjoining them, but also that the number of active forms including those nitrogen-fixing ones, was in general, remarkably higher. This suggests the possibility that microorganisms clean the nest air of the excess of nitrogen compounds. Earthworm secretions and soil surrounding them had more abundant microflora, when compared with the soil not influenced by earthworms. The species composition of earthworm microflora in the study area within the range of industrial emissions, was entirely different from that found in earthworms from the control area. Earthworms were introduced on polluted areas along with the organic matter under an amelioration treatment. Their activity although considerable, has to be evaluated as a short-term effect, since a sexually immature population is destined for extinction. It indicates that in the course of ameliorative treatments one has to consider not only vegetation requirements, but also those of soil organisms which condition the development and life of plants.
The barriers that people with disabilities face around the world are not only inherent in the limitations resulting from the disability itself, but, more importantly, these barriers rest with the societal technologies of exclusion. A multiple regression analysis was conducted to examine the statistical relationship between the national level of development, the level of democratization, and the level of education of a country's population on one hand, and expressed concern for people with disabilities on another hand. The results reveal that a greater worry for the well-being of people with disabilities is correlated with a high level of country development, a decreased value of political stability and absence of violence, a decreased level of government effectiveness, and a greater level of law enforcement. There is a direct correlation between concern for people with disabilities and people's awareness about disabilities. Surprisingly, the level of education has no impact on the compassion toward people with disabilities. A comparison case for in depth illustration is discussed. Copyright © 2014 Elsevier Ltd.

Full Text Available The importance of the market for polychaetes dramatically increased after the discovery of their potential as food in aquaculture. In Portugal, the gathering of polychaetes solely from natural populations is not sufficient to meet market demand, both as bait for sea anglers and as a food item in aquaculture. The requests for worms to polychaete dealers by Portuguese and Spanish seafarms have increased during recent years. Due to the lack of intensive culture of these worms in Portugal and the proximity of southern Spanish farms, a large component of imported polychaetes that arrive in Portugal at Lisbon Airport go directly to Spain by road. In 2002 and 2003 a total of 12,728,379 and 16,866,839 polychaetes respectively were imported to Europe via Lisbon Airport from China and the USA. In 2003 the imports from China and the USA realised 716,180 and 291,845 US dollars respectively. Two species were reported to have been imported in these years, namely the Korean blue ragworm Perinereis aibuhitensis and the American bloodworm Glycera dibranchiata. Imports of non-indigenous species, which are traded and sold alive, may increase the risk of accidental introduction into the wild. This is of special concern as Perinereis aibuhitensis has been successfully reared in captivity within the range of environmental conditions existing in the Ria Formosa coastal lagoon. Other risks associated with introduced species are the transport of foreign pathogens and other associated non-native organisms, which may act as carriers of disease.

This study reports a cross-cultural comparison of the vocal pitch patterns of 15 Mexican Spanish-speaking and 15 Belgian Flemish-speaking dyads, recorded during 5min of free-play in a laboratory setting. Both cultures have a tradition of dyadic face-to-face interaction but differ in language origins (i.e., Romanic versus Germanic). In total, 374 Mexican and 558 Flemish vocal exchanges were identified, analyzed and compared for their incidence of tonal synchrony (harmonic/pentatonic series), non-tonal synchrony (with/without imitations) and pitch and/or interval imitations. The main findings revealed that dyads in both cultures rely on tonal synchrony using similar pitch ratios and timing patterns. However, there were significant differences in the infants' vocal pitch imitation behavior. Additional video-analyzes on the contingency patterns involved in pitch imitation showed a cross-cultural difference in the maternal selective reinforcement of pitch imitation. The results are interpreted with regard to linguistic, developmental and cultural aspects and the 'musilanguage' model. Copyright © 2015 Elsevier Inc. All rights reserved.

The Youth Anxiety Measure-I for DSM-5 has recently been developed to assess youth's anxiety symptomatology. As social anxiety is one of the most common disorders in adolescence, this scale includes a subscale measuring social anxiety. However, psychometric properties of the YAM-5-I social anxiety subscale (YAM-5-I-SAD) in clinical samples are lacking. This paper aims to bridge the gap. The sample comprised 24 clinically diagnosed and 24 healthy control Spanish-speaking adolescents aged 14-17 years. Data revealed that the YAM-5- I-SAD yielded excellent sensitivity, which makes it particularly useful as a screening tool to early detect socially anxious adolescents. In addition, the YAM-5-I-SAD evidenced good internal consistency and construct validity. Data are limited to the social anxiety subscale. The YAM-5-I-SAD is a sensitive and specific measure to screen for adolescents with social anxiety. Copyright © 2018 Elsevier B.V. All rights reserved.

Full Text Available The regional government should provide ecological safety in order to ensure stable social and economic development of the country. The article outlines theoretical approach and recommendations on practice concerning ecological issues, investigates state policy aiming to preserve nature and analyses sources of threat to ecological safety in the region. The modern paradigm of the country’s and region’s development is characterized by the combination of ecological and economic policy. The ecological policy providing measures for efficient use of natural resources, their protection and restoration is implemented in the economic strategy of highly developed countries and encourages stable social and economic development of the country and the region. Some researchers assert that Russia’s most regions do not possess sufficient resources necessary to implement structural shifts which can eliminate the main threats to ecological safety. The Republic of Kalmykia can be included into this list. It is rich in natural resources but they are not restored due to the lack of regulation for efficient consumption. The main concerns of the republic are water supply, desertification, and pollution of atmosphere, waste disposal, and protection of wildlife and environment, preservation of hunting ground, forest management. The republic generates no electricity so it is delivered by neighboring regions. The republic should use the renewable ways of producing energy which can contribute to the energy and ecological safety and can attract new investment funds. There is an urgent need for stricter state regulation to ensure socioeconomic development and ecological safety in Kalmykia.

Ecology is a science that studies the mutual interactions between organisms and their environment. The fundamental subject of interest in ecology is the individual. Topics of interest to ecologists include the diversity, distribution and number of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems. Today, ecology is a multidisciplinary science. This is particularly true when the subject of interest is the ecosystem or biosphere, which requires the knowledge and input of biologists, chemists, physicists, geologists, geographists, climatologists, hydrologists and many other experts. Ecology is applied in a science of restoration, repairing disturbed sites through human intervention, in natural resource management, and in environmental impact assessments.

Invasive plants can impact biodiversity as well as the lives of native human populations. Natural ecosystems represent sources of natural resources essential for the subsistence and socio-cultural continuity of these social groups. Approximately 30,000 ha of Acacia mangium were planted for commercial purposes in savanna areas surrounding indigenous lands in Roraima State, Brazil, at the end of the 1990s. We examined the local ecological knowledge of indigenous Wapichana and Macuxi Amerindians, members of the Arawak and Carib linguistic families, respectively, concerning A. mangium Willdenow (Fabaceae) in a savanna ecosystem ("Lavrado") to attempt to understand its propagation beyond the limits of the commercial plantations and contribute to mitigating its impacts on socio-ecological systems. The present study was undertaken in the Moskow, São Domingos, and Malacacheta communities in the Moskow and Malacacheta Indigenous Lands (ILs) in the Serra da Lua region of Roraima State, in the northern Brazilian Amazon region. Interviews were conducted with a total of 94 indigenous individuals of both sexes, with ages between 18 and 76, and low levels of formal schooling, with an average time of permanence in the area of 21 years; some still spoke only their native languages. The interviews focused on their ecological knowledge of the invasive, non-native A. mangium and their uses of it. The informants affirmed that A. mangium negatively impacted the local fauna and flora, making their subsistence more difficult and altering their daily routines. Among the problems cited were alterations of water quality (71.3%), negative impacts on crops (60.6%), negative impacts on the equilibrium of the local fauna (52.1%), increased farm labor requirements (41.5%), and restriction of access to indigenous lands (23.4%). There were no significant differences between the opinions of men and women, nor between community leaders and nonleaders. Most of the interviewees (89%) felt that A

Objective The purpose of this study was to examine the most effective and available English and Spanish language caregiver assessments for providers and caregivers. Methods Assessments were included if they screened for caregiving-related concerns, including stress, depression, and caregiving burden and could be administered directly to caregivers in person or online. Results Eighteen assessments are designed to assess caregiver burden, distress, depression, and grief. Six did not have psychometric data to support efficacy but are widely used in clinical and research settings. Six were validated in Spanish, and one other is available in Spanish but not validated. Conclusion As many as 80% of care recipients are cared for in the home by family members who act as informal caregivers. Caregivers of persons with dementia may experience depression symptoms, high caregiver burden, and feelings of being constrained. Due to the lack of psychometric evidence available, the validity of some assessments is questionable.

The upper portion of Lower Three Runs includes several ponds, reservoirs, and canals that were formerly used as a cooling system for nuclear production reactors. This area was divided into nine exposure areas (EAs) for the assessment of environmental contamination resulting from past reactor operations and other industrial processes. A tiered screening process identified several contaminants of potential concern including aluminum, cyanide, lead, manganese, mercury, DDD, DDE, and DDT. Risks posed by these contaminants to ecological receptors (river otter, belted kingfisher, raccoon, and blue heron) were assessed using contaminant exposure models that estimated contaminant intake resulting from ingestion of food, water, and sediment/ soil and compared these intakes with toxicity reference values (TRVs). The contaminant exposure models showed that the TRVs were not exceeded in the otter model, exceeded by aluminum in EA 7 (Pond 2 and associated canals) in the raccoon model, and exceeded by mercury in EAs 2, 3 (Pond B), 6 (Par Pond), and 8 (Ponds 4 and 5 and Canal to Pond C) in both the kingfisher and blue heron models. Hazard quotients (total exposure dose divided by the TRV) were 2.8 for aluminum and 1.7- 3.6 for mercury. The primary route of exposure for aluminum was the ingestion of soil, and the primary route of exposure for mercury was the ingestion of mercury contaminated fish. Elevated levels of mercury in fish were at least partly the result of the aerial deposition of mercury onto Lower Three Runs and its watershed. The atmospheric deposition of mercury creates pervasive contamination in fish throughout the Savannah River basin. Another possible source of mercury was the discharge of mercury contaminated Savannah River water into the Lower Three Runs cooling ponds and canals during previous years of reactor operation. This contamination originated from industries located upstream of the SRS. The aluminum exceedance for the raccoon was likely the result of

Tobacco cessation training programs to treat tobacco dependence have measureable effects on patients' smoking. Tobacco consumption in low- and middle-income countries (LMICs) is high and slowly decreasing, but these countries usually lack measures to face the epidemic, including tobacco cessation training programs for health professionals and organizations. Based on a previous online smoking cessation training program for hospital workers in Spain, the Fruitful Study aims to increase smoking cessation knowledge, attitudes, self-confidence, and performance interventions among health care professionals of three Spanish-speaking low- and middle-income Latin American and Caribbean (LAC) countries. The purpose of this paper is to describe the methodology and evaluation strategy of the Fruitful Study intended to adapt, implement, and test the effectiveness of an online, evidence-based tobacco cessation training program addressed to health professionals from Bolivia, Guatemala, and Paraguay. This study will use a mixed-methods design with a pre-post evaluation (quantitative approach) and in-depth interviews and focus groups (qualitative approach). The main outcomes will be (1) participants' attitudes, knowledge, and behaviors before and after the training; and (2) the level of implementation of tobacco control policies within the hospitals before and after the training. To date, adaptation of the materials, study enrollment, and training activities have been completed. During the adaptation, the main mismatches were language background and content adaptation. Several aids were developed to enable students' training enrollment, including access to computers, support from technicians, and reminders to correctly complete the course. Follow-up data collection is in progress. We have enrolled 281 hospital workers. Results are expected at the beginning of 2017 and will be reported in two follow-up papers: one about the formative evaluation and the other about the summative

Although Small Hydropower Projects (SHPs) are encouraged as sources of clean and green energy, there is a paucity of research examining their socio-ecological impacts. We assessed the perceived socio-ecological impacts of 4 SHPs within the Western Ghats in India by conducting semi-structured interviews with local respondents. Primary interview data were sequentially validated with secondary data, and respondent perceptions were subsequently compared against the expected baseline of assured impacts. We evaluated the level of awareness about SHPs, their perceived socio-economic impacts, influence on resource access and impacts on human-elephant interactions. The general level of awareness about SHPs was low, and assurances of local electricity and employment generation remained largely unfulfilled. Additionally most respondents faced numerous unanticipated adverse impacts. We found a strong relationship between SHP construction and increasing levels of human-elephant conflict. Based on the disparity between assured and actual social impacts, we suggest that policies regarding SHPs be suitably revised.

Urban growth is a complex dynamical process associated with landscape change driving forces such as the environment, politics, geography and many others that affect the city at multiple spatial and temporal scales. Istanbul, one of the largest agglomerations in Europe and the fifth-largest city in the world in terms of population within city limits, has been growing very rapidly over the late 20th century at a rate of 3.45 %, causing to have many environmental issues. Recently, Istanbul's new third bridge and proposed new routes for across the Bosphorus are foreseen to not only threaten the ecology of the city, but also it will give a way to new areas for unplanned urbanization. The dimensions of this threat are affirmed by the urban sprawl especially after the construction of the second bridge and the connections such as Trans European Motorway (TEM). Since the spatial and temporal components of urbanization can be more simply identified through modeling, this study aims to analyze the urban change and assess the ecological threats in Istanbul city through the proper modeling for the year 2040. For this purpose, commonly used urban modeling approach, the Markov Chain within Cellular Automata (CA), was selected to simulate urban/non-urban growth process. CA is a simple and effective tool to capture and simulate the complexity of urban system dynamic. The key factor for a Markov is the transition probability matrix, which defines change trend from past to today and into the future for a certain class type, and land use suitability maps for urban. Multi Criteria Analysis was used to build these suitability maps. Distance from each pixel to the urban, road and water classes, plus the elevation, slope and land use maps (as excluded layer) were defined as factors. Calibration data were obtained from remotely sensed data recorded in 1972, 1986 and 2013. Validation was performed by overlaying the simulated and actual 2013 urban maps and Kappa Index of Agreement was

Full Text Available The principal purpose of this study has been to analyze the cognitive processes and spelling skills in Spanish-speaking English-language learners. A sample of English-speaking Canadian learners and Spanish-speaking English-language learners was selected from different Canadian schools in the Vancouver District within British Columbia's province. We examined cognitive and spelling skills of English-speaking students and Spanish-speaking English language learners in the primary grades. We hypothesized that there would be a positive transfer from cognitive and linguistic processes from L1 to L2 spelling skills development, if no significant differences were observed among native English speakers and Spanish-language learners on these measures. There were no significant differences between the English –language learners and the native English speakers on measures of phonological awareness and spelling skills. However, English-speaking Canadian learners performed better than Spanish-speaking English-language learners on vocabulary and syntactic awareness. El objetivo principal de este estudio ha sido analizar los procesos cognitivos y de escritura de niños hispano-parlantes que aprenden el inglés como segunda lengua. Para ello se seleccionó a una muestra de niños canadienses de habla inglesa y otra de hispano-parlantes que reciben instrucción en inglés como segunda lengua en escuelas canadienses del distrito de Vancouver en la provincia canadiense de Columbia Británica (British Columbia. Se tomaron medidas de competencia lingu?ística (vocabulario y conciencia sintáctica, memoria de trabajo, conciencia fonológica y escritura de palabras y pseudopalabras en inglés para el grupo de monolingu?es, y las mismas medidas en los idiomas inglés y español para el grupo de hispano-parlantes. Nuestra predicción es que si existe un efecto de transferencia de L1 sobre L2 entonces existiría relación entre los procesos cognitivos y de escritura que
Full Text Available Teesid: Artikkel esitab bio-bibliograafilise ülevaate luuletaja, esseisti, kirjandusteadlase, tõlkija ning õppejõu Jüri Talveti (s 1945 loomingulisest teest. Talveti kui erakordselt laiahaardelise loomingulise isiksuse panus hispaaniakeelse kirjandusruumi vahendamisel ja uurimisel Eestis on jätnud püsiva jälje. Tema viljeldava komparativismi keskmeks olev võrdlus ei piirdu üksnes võrreldavate objektidega, vaid viib põimumiste ja mõjutuste väljaselgitamisele ning uue sünteesini. Niisugune lähenemine võimaldab Talvetil esitada mitmeid eesti kirjanduskultuuri keskseid autoreid ja teoseid maailmakirjanduslikus kontekstis. Luuletajana esindab Talvet hingestatud intellektuaalsust, milles intertekstuaalsed osutused toimivad kultuuridevahelise sillana. The article presents a bio- and bibliographical overview of the creative work of Jüri Talvet (born in 1945 – a poet, essayist, literary scholar, translator and university professor. The creative scope of Talvet is exceptionally wide and his decades-long contribution to the mediation and exploration of the Spanish-speaking literary space in Estonia has left permanent traces. The comparative method cultivated by Talvet does not border merely on the literary texts considered but lead to the establishment of reciprocal impact and a new level of synthesis. Terms such as “symbiosis”, “symbiotic unity” and “synthesis” play an important role in Talvet’s contemplations of life, literature and culture; they are not only part of his epistemological ’toolkit’ but also represent a relation of value. In the semiotic approach such discourse may be viewed as the replacement of binary structure with a ternal one, a change elaborated already by Talvet’s most famous colleague Juri Lotman in 1992 when his intellectual testament Culture and Explosion was published: “Ternal structures retain certain values of the previous period by shifting them from the periphery into the centre

Del total, 87% reconocieron no haber incluido referencias importantes en artículos publicados por no disponer del texto completo y 56% afirmaron haber citado artículos que no habían leído. Además, 7,6% de los encuestados reconocieron haber consultado bases de datos de acceso restringido mediante claves prestadas o discos copiados. Más de dos tercios de los autores manifestaron que obtenían los textos completos de los artículos mediante fotocopia o directamente de los autores. CONCLUSIONES: Es necesario entrenar a los investigadores latinoamericanos en la utilización de las bases de datos de uso más frecuente -especialmente MEDLINE- y mejorar su acceso a las fuentes bibliográficas biomédicas, como medidas esenciales para fomentar el desarrollo de la producción científica en la Región.OBJECTIVE: To describe how Spanish-speaking biomedical professionals in Latin America access and utilize bibliographic databases. METHODS: Based on a MEDLINE search, 2 515 articles published between August 2002 and August 2003 were identified that dealt with and/or had authors from 16 countries: Argentina, Bolivia, Chile, Colombia, Costa Rica, Cuba, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, and Venezuela. The search was limited to references to basic science, clinical science, or social medicine. A survey was sent by e-mail to researchers who lived in 15 of the 16 countries (the exception being Nicaragua. The survey asked about the researcher's area of work (basic science, clinical science, or public health, the level of skill in using databases, the frequency and type of access to the databases most utilized, the impact from not having access to the full text of articles when preparing a manuscript, and how the respondent usually obtained the full-text version of

In this study, we aimed to estimate the effect that environmental, demographic, and socioeconomic factors have on dengue mortality in Latin America and the Caribbean. To that end, we conducted an observational ecological study, analyzing data collected between 1995 and 2009. Dengue mortality rates were highest in the Caribbean (Spanish-speaking and non-Spanish-speaking). Multivariate analysis through Poisson regression revealed that the following factors were independently associated with dengue mortality: time since identification of endemicity (adjusted rate ratio [aRR] = 3.2 [for each 10 years]); annual rainfall (aRR = 1.5 [for each 103 L/m2]); population density (aRR = 2.1 and 3.2 for 20–120 inhabitants/km2 and > 120 inhabitants/km2, respectively); Human Development Index > 0.83 (aRR = 0.4); and circulation of the dengue 2 serotype (aRR = 1.7). These results highlight the important role that environmental, demographic, socioeconomic, and biological factors have played in increasing the severity of dengue in recent decades. PMID:22302870
Variations in recruitment yield, costs, speed and participant diversity across Internet platforms in a global study examining the efficacy of an HIV/AIDS and HIV testing animated and live-action video among English- or Spanish-speaking Internet or social media users
Full Text Available For a world-wide, Internet-based study on HIV/AIDS and HIV testing knowledge, we compared the yields, speed and costs of recruitment and participant diversity across free postings on 13 Internet or social media platforms, paid advertising or postings on 3 platforms, and separate free postings and paid advertisements on Facebook. Platforms were compared by study completions (yield, time to completion, completion to enrollment ratios (CERs, and costs/completion; and by participants’ demographic characteristics, HIV testing history, and health literacy levels. Of the 482 English-speaking participants, Amazon Mechanical Turk yielded the most participants, recruited participants at the fastest rate and had the highest CER (0.78 and lowest costs/completion. Of the 335 Spanish-speaking participants, Facebook yielded the most participants and recruited participants at the fastest rate, although Amazon Mechanical Turk had the highest CER (0.72 and lowest costs/completion. Across platforms participants differed substantially according to their demographic characteristics, HIV testing history and health literacy skills.

VARIATIONS IN RECRUITMENT YIELD, COSTS, SPEED AND PARTICIPANT DIVERSITY ACROSS INTERNET PLATFORMS IN A GLOBAL STUDY EXAMINING THE EFFICACY OF AN HIV/AIDS AND HIV TESTING ANIMATED AND LIVE-ACTION VIDEO AMONG ENGLISH- OR SPANISH-SPEAKING INTERNET OR SOCIAL MEDIA USERS.
Shao, Winnie; Guan, Wentao; Clark, Melissa A; Liu, Tao; Santelices, Claudia; Cortés, Dharma E; Merchant, Roland C
For a world-wide, Internet-based study on HIV/AIDS and HIV testing knowledge, we compared the yields, speed and costs of recruitment and participant diversity across free postings on 13 Internet or social media platforms, paid advertising or postings on 3 platforms, and separate free postings and paid advertisements on Facebook. Platforms were compared by study completions (yield), time to completion, completion to enrollment ratios (CERs), and costs/ completion; and by participants' demographic characteristics, HIV testing history, and health literacy levels. Of the 482 English-speaking participants, Amazon Mechanical Turk yielded the most participants, recruited participants at the fastest rate and had the highest CER (0.78) and lowest costs / completion. Of the 335 Spanish-speaking participants, Facebook yielded the most participants and recruited participants at the fastest rate, although Amazon Mechanical Turk had the highest CER (0.72) and lowest costs/completion. Across platforms participants differed substantially according to their demographic characteristics, HIV testing history and health literay skills. The study results highlight the need for researchers to strongly consider choice of Internet or social media plaforms when conducting Internet-based research. Because of the sample specifications and cost restraints of studies, specific Internet/ social media or participant selection plaforms will be much more effective or appropriate than others.

The current safety analysis, SR 97, compares three sites in Sweden. This report compares the biosphere for the three areas, Aespoe, Finnsjoen and Gideaa, which have been studied to describe the conditions at three hypothetical sites, Aberg, Beberg and Ceberg. Data from these sites will be used in analysis and to make realistic models of the biosphere development. The report is based on a literature study considering climate, physical geography, vegetation, ecology, land use, environment and population. Data from each site is presented separately and is compared for present conditions and from a future perspective. The locations of the sites along the south-north gradient influences the climate, temperature, vegetation period and precipitation. Aberg has a more humid climate with a longer vegetation period, a higher mean temperature, a higher diversity and a faster turn-over time than Beberg and Ceberg. There is also a difference in land use, where Beberg has the greatest potential for agriculture, because of the soil types and topography. Abergs location in the archipelago makes it very exposed to shore level displacement, compared to Beberg and Ceberg with a higher elevation. The highest population density is found in Aberg, but Beberg has the highest potential for increase. Simplified models made from present and future biosphere conditions, show that the sites have different prerequisite concerning biosphere factors. The parameters that may affect the ecosystem and the biosphere over time are more likely to change in Aberg due to position above sea level, climate, sea level displacement and land use. Biosphere changes are however in a long time perspective hard to predict. The models used in this report are a suggestion on how to evaluate biological data in a more thorough study. 99 refs, 14 figs, 31 tabs

This series of A-level social biology topic books responds to the changing demands of social biology syllabuses, with each text dealing with a particular area of interest. Although the series is primarily intended for students of A-level social biology, the books will appeal to students studying a wide range of biological subjects at A-level. Environmental Concerns covers topics common to several A-level human and social biology syllabuses. It is particularly relevant to the human ecology and conservation options. The text focuses on the social and economic implications of current ecological issues as well as the basic biological concepts involved. It deals with the causes, effects and prevention of atmospheric and water pollution as well as with the disruption of ecosystems by changes in land use. The conflict of interests between conservation and exploitation is discussed, along with management techniques including the controversial method of culling to maintain diversity. The moral and aesthetic aspects of conservation and management are emphasised throughout, in addition to the scientific background of these techniques.
Full Text Available In this paper, we will present data from both Spanish acquisition and aphasia on the Pronoun Interpretation Problem (PIP, according to which children allow pronouns to be identified with local c-commanding antecedents. Although it has recently been claimed that the PIP is, to a great extent, an experimental artifact, there are good reasons to believe that there is something “real” in the effect. As with many phenomena from acquisition, researchers have tried to explain this development in terms of “learning”, or more concretely, in terms of “parameter setting”. Children either must set the right local domain for the application of Principle B or they must set a +/− Principle B parameter. However, considering the PIP as an acquisition problem is problematic since it is difficult to see how children can converge on the target grammar without negative evidence. In this paper, we will defend an alternative approach, according to which the PIP is portrayed as the result of interplay between properties of predicates and different kinds of pronouns on the one hand, and language processing factors on the other.

The purpose of this study was to explore how the inquiry of cultural diabetes causation beliefs can improve Hispanic/Latino patient self-management. Two semistructured focus groups were conducted with 13 Hispanic/Latinos adults diagnosed with type 2 diabetes mellitus. Prior to taking part in the group discussion, participants completed a demographic survey and the Illness Perception Questionnaire-Revised. The top 5 diabetes causation items endorsed by participants per the questionnaire included stress or worry, behavior, hereditary, diet/eating habits, and family problems/worries. The qualitative analysis revealed stress as a recurring theme for a cause of diabetes. Work stress was specifically identified as a contributor to unhealthy eating and diabetes. Most participants were aware of and believed in susto and referred to it as coraje (anger). Participants believed that asking patients about their diabetes causation beliefs and emotional status can help health professionals (1) better understand the patient and (2) identify and prioritize diabetes treatments. Participants also indicated that the role of doctors is important and the encouragement that they give to patients is clinically and spiritually valued. Stress was identified as a cause of diabetes in addition to unhealthy diets and heredity. Asking patients about diabetes causation beliefs and emotional status may help prioritize treatment and management goals. © 2015 The Author(s).

The objective of this study was to analyse the mailing list RADIOLOGIA during its first 5 years of operation (from 1998 to 2003). A survey questionnaire was sent to evaluate the characteristics of subscribers and to score (from 0 to 9) the functionality, usefulness and quality of the mailing list. All messages sent to the list during the evaluated period were classified and quantified. A social network analysis was performed from all messages replied to during 2001 and 2002 with the option 'reply to' included in the subject. One hundred and forty (36.8%) responses were collected from 380 subscribers, mainly radiologists (90.0%). 80% of responders were located in Spain, 16% in Latin America, and 4% in other places. The obtained scores (mean ± standard deviation) were: functionality 7.4 ± 1.3; usefulness 7.0 ± 1.4; and quality of e-mail contents 6.0 ± 1.4. During the evaluated period 2700 e-mail messages were sent to the list, with a monthly distribution of 44.3 ± 26.0. The list functioning has been based on an active minority of subscribers that provided information and responses to the rest of the subscribers, a ring of active members that participated in discussions, and about 50% of passive members

Full Text Available As a reaction to the few existing descriptions of headlines, descriptions which in some respects often fail the empirical proof of comparing them to the observable newspapers reality, it is proposed an updated set of the most distinctive formal features of headlines, according to their distribution within a large corpus of current newspapers in Spanish. The set is summarized in four constant and four variable features. The constant features —relatively homogeneous throughout the corpus (although some of its variants have certain conditions— are: expressive bimembration, ellipsis, nominal structures and historical present. On the other hand, the variable traits —which show a not so regular distribution— are: impersonal third person, verb in starting position, quoting conditional and anthroponyms abbreviated by initializations. The analysis is based on a corpus of 3 689 recent headlines published in Spanish in the printed editions of the following newspapers: El País, from Madrid (Spain; La Opinión, from Los Angeles (United States; El Universal, from Mexico City (Mexico; La Nación, from San Jose (Costa Rica; Hoy, from Santo Domingo (Dominican Republic; El Tiempo, from Bogota (Colombia; El Nacional, from Caracas (Venezuela; El Comercio, from Lima (Peru; El Mercurio, from Santiago (Chile, and Clarín, from Buenos Aires (Argentina. Where appropriate, the diatopic factor is considered, and the inaccuracy of some frequent approaches is also demonstrated.

Among the approaches to the demoralization syndrome, the one proposed by Kissane et al. is prevalent in the literature. These authors developed the Demoralization Scale (DS) to assess emotional distress, conceived as demoralization. To present the Spanish adaptation of the Demoralization Scale in palliative care patients, with a new and more comprehensive approach to its factorial structure. A cross-sectional study was carried out in 226 Spanish palliative care patients in three different settings: hospital, home care unit, and continued care unit. Outcome measures included the DS and the Hospital Anxiety and Depression Scale. Analyses comprised confirmatory factor analyses to test the original, German, and Irish structure of the DS, exploratory structural equation modeling (ESEM), estimations of internal consistency, and multivariate analyses of variance for criterion-related validity. The confirmatory factor analyses showed inappropriate fit for the previous structures when studied in the Spanish version of the DS. With ESEM, the best fitting structure was the five-factor solution, without item 18. Reliability results offered good estimations of internal consistency for all the dimensions except for sense of failure. Cronbach alpha coefficients were appropriate for the dimensions of loss of meaning (0.86), helplessness (0.79), disheartenment (0.88), and dysphoria (0.80), but low reliability was found for sense of failure (0.62). Convergent and discriminant validity showed positive correlations between demoralization, anxiety, and depression. Patients with higher levels of anxiety had higher scores on every dimension of demoralization, and those with higher levels of depression had higher scores on loss of meaning, disheartenment, and sense of failure, but not on dysphoria or helplessness. The Spanish adaptation of the DS has shown appropriate psychometric properties. It has been useful to differentiate between depression and the demoralization syndrome, pointing to helplessness and dysphoria as unique characteristics of demoralized palliative care patients.

To develop, pilot test, and conduct psychometric analyses of an innovative scale measuring the influence of perceived immigration laws on Latino migrants' HIV-testing behavior. The Immigration Law Concerns Scale (ILCS) was developed in three phases: Phase 1 involved a review of law and literature, generation of scale items, consultation with project advisors, and subsequent revision of the scale. Phase 2 involved systematic translation- back translation and consensus-based editorial processes conducted by members of a bilingual and multi-national study team. In Phase 3, 339 sexually active, HIV-negative Spanish-speaking, non-citizen Latino migrant adults (both documented and undocumented) completed the scale via audio computer-assisted self-interview. The psychometric properties of the scale were tested with exploratory factor analysis and estimates of reliability coefficients were generated. Bivariate correlations were conducted to test the discriminant and predictive validity of identified factors. Exploratory factor analysis revealed a three-factor, 17-item scale. subscale reliability ranged from 0.72 to 0.79. There were significant associations between the ILCS and the HIV-testing behaviors of participants. Results of the pilot test and psychometric analysis of the ILCS are promising. The scale is reliable and significantly associated with the HIV-testing behaviors of participants. Subscales related to unwanted government attention and concerns about meeting moral character requirements should be refined.

Applied ecology is evolved into a principal part of modern ecology that rapidly develops. The major stimulus for the development of applied ecology roots in seeking the solutions for the problems of human populations, resources and environments. Through four decades, the science of applied ecology has been becoming a huge group of disciplines. The future for the applied ecology should concern more with human-influenced and managed ecosystems, and acknowledge humans as the components of ecosystems. Nowadays and in future, the top-priorities in applied ecology should include following fields: sustainable ecosystems and biosphere, ecosystem services and ecological design, ecological assessment of genetically modified organisms, ecology of biological invasions, epidemical ecology, ecological forecasting, ecological process and its control. The authors believe that the comprehensive and active research hotspots coupled some new traits would occur around these fields in foreseeable future.

Ecology (from the Greek words οιχοσ, "house" and λογια "study of") is the science of the "house", since it studies the environments where we live. There are three main ways of thinking about Ecology: Ecology as the study of interactions (between humans and the environment, between humans and living beings, between all living beings, etc.), Ecology as the statistical study of interactions, Ecology as a faith, or rather as a science that requires a metaphysical view. The history of Ecology shows us how this view was released by the label of "folk sense" to gain the epistemological status of science, a science that strives to be interdisciplinary. So, the aim of Ecology is to study, through a scientific methodology, the whole natural world, answering to very different questions, that arise from several fields (Economics, Biology, Sociology, Philosophy, etc.). The plurality of issues that Ecology has to face led, during the Twentieth-century, to branch off in several different "ecologies". As a result, each one of these new approaches chose as its own field a more limited and specific portion of reality.

The most pressing problems facing humanity today - over-population, energy shortages, climate change, soil erosion, species extinctions, the risk of epidemic disease, the threat of warfare that could destroy all the hard-won gains of civilization, and even the recent fibrillations of the stock market - are all ecological or have a large ecological component. in this volume philosophers turn their attention to understanding the science of ecology and its huge implications for the human project. To get the application of ecology to policy or other practical concerns right, humanity needs a clear and disinterested philosophical understanding of ecology which can help identify the practical lessons of science. Conversely, the urgent practical demands humanity faces today cannot help but direct scientific and philosophical investigation toward the basis of those ecological challenges that threaten human survival. This book will help to fuel the timely renaissance of interest in philosophy of ecology that is now oc...

In 1956 P.W. Bridgman published a letter to the editor in the Journal of Applied Physics reporting results of electrical resistance measurements on iron under static high pressure. The work was undertaken to verify the existence of a polymorphic phase transition at 130 kbar (13 GPa) reported in the same journal and year by the Los Alamos authors, Bancroft, Peterson and Minshall for high pressure, shock-compression loading. In his letter, Bridgman reported that he failed to find any evidence for the transition. Further, he raised some fundamental concerns as to the state of knowledge of shock-compression processes in solids. Later it was determined that Bridgman's static pressure scale was in error, and the shock observations became the basis for calibration of pressure values in static high pressure apparatuses. In spite of the error in pressure scales, Bridgman's concerns on descriptions of shock-compression processes were perceptive and have provided the basis for subsequent fundamental studies of shock-compressed solids. The present paper, written in response to receipt of the 1993 American Physical Society Shock-Compression Science Award, provides a brief contemporary assessment of those shock-compression issues which were the basis of Bridgman's 1956 concerns
Deborah Oughton started with a view of the work in progress by the ICRP TG 94 on ethics, from the historical context and the principles-based ethics in RP, to continue with an overview of the ethical theories and with the main area of elaboration which concerns the common values, to conclude with considerations about the implementation in different area such as biomedicine, nuclear safety and workers, ecological aspects, and environmental health and society. By reading again the ICRP and IAEA publications on the ethical aspects in the protection of environment from the effects of ionizing radiation, the presentation covers the various and different cultures within the history of environmental ethics, the perception of Nature and the theories of environmental ethics, in particular by focusing on anthropocentrism, biocentrism and ecocentrism, as philosophical worldwide views, and on conservation, biodiversity, sustainability, environmental justice and human dignity, as primary principles of environmental protection. The influence of western Christianity, with a view of man dominating over every creeping thing on earth, and of the non-western ideas, the human perception of Nature has been analyzed and discussed to conclude that, in reality then, the anthropocentrism, biocentrism and ecocentrism, as reflected in many cultures and religions, they all support the need to protect the environment and to recognise and preserve the diversity. Three challenges were then discussed in the presentation: the ecosystem approach and ecological economics, for example in the case of Fukushima by asking what is the economic cost of marine contamination; the ecosystem changes with attention to what harms, as in the case of the environment in the contaminated areas around Chernobyl; and the environmental consequences of remediation, which can be considered a source of controversy for environmental ethics and policy

At Itaipu, on the Rio Parana, Brazil and Paraguay are constructing the world's largest hydro-electric power plant with a capacity seven times as high as that of Assuan. An information system is intended to give fair warning in case of threatening ecological conditions. The computer-supported alarm system had four objectives: 1. presentation of the present ecological situation; 2. evaluation of the ecological risks; 3. warning about ecological deficits; 4. suggestions for establishing ecological stability. In a first step the available inventory data concerning soil, topography, vegetation and water were evaluated by expert groups according to their risk grade (0-4) and ecological weight (1-10). The product of these evaluations indicates the ecological deficit (0-40). At a threshold value of 30, the information system automatically signals ecological alarm and locates the centre of danger via computer-plotted maps and tables. The necessary data are supplied periodically by selected measurement stations. Quantification of ecological facts enables the persons who are responsible for decisions at Itaipu to recognize, avoid, or diminish elements of danger even if they have little or no ecological knowledge. The file of data that has been compiled so far should be extended parallel with the development in the Itaipu area. With the help of factor analysis connections of cause and effect can be detected in this extremely complex reservoir system which has hardly been explored yet.

We then show that the initiatives to promote Portuguese in Latin America have strengthened in the wake of recent changes in Brazilian foreign policy. In addition to this, we argue that, as an instrument of language policy, the Certificate of Proficiency in Portuguese as a Foreign Language (Celpe-Bras has particular potential in this region. To conclude, we highlight essential points for the planning of the policy for promoting Portuguese abroad.

This paper maps a coevolutionary research agenda for ecological economics. At an epistemological level coevolution offers a powerful logic for transcending environmental and social determinisms and developing a cross-disciplinary approach in the study of socio-ecological systems. We identify four consistent stories emerging out of coevolutionary studies in ecological economics, concerning: environmental degradation and development failure in peripheral regions; the lock-in of unsustainable production-consumption patterns; the vicious cycle between human efforts to control undesirable micro-organisms and the evolution of these organisms; and the adaptive advantages of other-regarding, cooperative behaviors and institutions. We identify challenges in the conceptualization of coevolutionary relationships in relation to: the interaction between different hierarchical levels of evolution; the role of space and social power; uneven rates of change and crises. We conclude with the political implications of a coevolutionary perspective based on the premises of pragmatism. (author)
This book presents the proceedings of a workshop on community ecology organized at Davis, in April, 1986, sponsored by the Sloan Foundation. There have been several recent symposia on community ecology (Strong et. al., 1984, Diamond and Case, 1987) which have covered a wide range of topics. The goal of the workshop at Davis was more narrow: to explore the role of scale in developing a theoretical approach to understanding communities. There are a number of aspects of scale that enter into attempts to understand ecological communities. One of the most basic is organizational scale. Should community ecology proceed by building up from population biology? This question and its ramifications are stressed throughout the book and explored in the first chapter by Simon Levin. Notions of scale have long been important in understanding physical systems. Thus, in understanding the interactions of organisms with their physical environment, questions of scale become paramount. These more physical questions illustrate the...

What is the subject of ecology? What is the primary concern of economics? How can the interface between ecology and economics be described? Is there a relationship between the two different sciences which constitutes a new research field? This book raises some of these basic questions and reflects on major misleading assumptions research in ecological economics unwittingly relies on. An outlook is given as to the aspects on which research in this field should now primarily concentrate. This publication addresses first of all natural scientists and politicians, though economists, too, might find some new aspects apart from traditional economic reasoning. (orig./KW)

Many children who die are eligible for hospice enrollment but little is known about parental perceptions of the hospice experience, the benefits, and disappointments. The objective of this study was to explore parental perspectives of the hospice experience in children with cancer, and to explore how race/ethnicity impacts this experience. We held 20 semistructured interviews with 34 caregivers of children who died of cancer and used hospice. Interviews were conducted in the caregivers' primary language: 12 in English and 8 in Spanish. Interviews were recorded, transcribed, and analyzed using accepted qualitative methods. Both English and Spanish speakers described the importance of honest, direct communication by medical providers, and anxieties surrounding the expectation of the moment of death. Five English-speaking families returned to the hospital because of unsatisfactory symptom management and the need for additional supportive services. Alternatively, Spanish speakers commonly stressed the importance of being at home and did not focus on symptom management. Both groups invoked themes of caregiver appraisal, but English-speaking caregivers more commonly discussed themes of financial hardship and fear of insurance loss, while Spanish-speakers focused on difficulties of bedside caregiving and geographic separation from family. The intense grief associated with the loss of a child creates shared experiences, but Spanish- and English-speaking parents describe their hospice experiences in different ways. Additional studies in pediatric hospice care are warranted to improve the care we provide to children at the end of life.

Rhythm is the speech property related to the temporal organization of sounds. Considerable evidence is now available for suggesting that dementia of Alzheimer's type is associated with impairments in speech rhythm. The aim of this study is to assess the use of an automatic computerized system for measuring speech rhythm characteristics in an oral reading task performed by 45 patients with Alzheimer's disease (AD) compared with those same characteristics among 82 healthy older adults without a diagnosis of dementia, and matched by age, sex and cultural background. Ranges of rhythmic-metric and clinical measurements were applied. The results show rhythmic differences between the groups, with higher variability of syllabic intervals in AD patients. Signal processing algorithms applied to oral reading recordings prove to be capable of differentiating between AD patients and older adults without dementia with an accuracy of 87% (specificity 81.7%, sensitivity 82.2%), based on the standard deviation of the duration of syllabic intervals. Experimental results show that the syllabic variability measurements extracted from the speech signal can be used to distinguish between older adults without a diagnosis of dementia and those with AD, and may be useful as a tool for the objective study and quantification of speech deficits in AD.

Usando la teoría del framing , este estudio analiza la manera en que los medios digitales en español enmarcan las noticias sobre cc . Se llevó a cabo un análisis de contenido de 889 noticias de 97 medios que publicaron noticias sobre cc durante las Cumbres de Cancún (2010 y Durban (2011. Los resultados muestran prevalencia de los políticos como fuentes y de agencias noticiosas. También indican una relación entre la fuente y el marco noticioso. Se discute que existe una “domesticación nacionalista” y que no responde a necesidades locales. Se sugieren nuevas investigaciones de corte cualitativo y comparativo.

This article is a report of qualitative findings of a mixed-methods study of the relationships among knowledge, self-efficacy, health promoting behaviors, and type 2 diabetes mellitus (T2DM) self-management among limited-english-proficient recent Hispanic immigrants, a population with increased incidence of T2DM and barriers to successful T2DM management. Semi-structured interviews were conducted with 30 participants, and physiological and demographic data also were collected. The participants generally attributed developing the disease to strong emotions and viewed T2DM as a serious disease. Although a majority understood the importance of exercise and diet in T2DM self-management, other aspects such as medication adherence were not well-understood. Obstacles to effective T2DM self-management were negative interactions and communications with health care providers and other personnel, cultural stigma related to the disease, financial constraints, immigration status, and the complexity of the disease. Suggested interventions to improve the care and self-management of this at-risk population are discussed. © 2017 Wiley Periodicals, Inc.

As the United States becomes more linguistically and culturally diverse, there is a need for effective health communication interventions that target diverse and most vulnerable populations. Latinos also have the lowest colorectal (CRC) screening rates of any ethnic group in the U.S. To address such disparities, health communication interventionists are often faced with the challenge to adapt existing interventions from English into Spanish in a way that retains essential elements of the original intervention while also addressing the linguistic needs and cultural perspectives of the target population. We describe the conceptual framework, context, rationale, methods, and findings of a formative research process used in creating a Spanish language version of an evidenced-based (English language) multimedia CRC screening decision aid. Our multi-step process included identification of essential elements of the existing intervention, literature review, assessment of the regional context and engagement of key stakeholders, and solicitation of direct input from target population. We integrated these findings in the creation of the new adapted intervention. We describe how we used this process to identify and integrate socio-cultural themes such as personalism (personalismo), familism (familismo), fear (miedo), embarrassment (verguenza), power distance (respeto), machismo, and trust (confianza) into the Spanish language decision aid.

To generate normative data on the Symbol Digit Modalities Test (SDMT) across 11 countries in Latin America, with country-specific adjustments for gender, age, and education, where appropriate. The sample consisted of 3,977 healthy adults who were recruited from Argentina, Bolivia, Chile, Cuba, El Salvador, Guatemala, Honduras, Mexico, Paraguay, Peru, and, Puerto Rico. Each subject was administered the SDMT as part of a larger neuropsychological battery. A standardized five-step statistical procedure was used to generate the norms. The final multiple linear regression models explained 29-56% of the variance in SDMT scores. Although there were gender differences on the SDMT in Mexico, Honduras, Paraguay, and Guatemala, none of the four countries had an effect size greater than 0.3. As a result, gender-adjusted norms were not generated. This is the first normative multicenter study conducted in Latin America to create norms for the SDMT; this study will have an impact on the future practice of neuropsychology throughout the global region.

The Community Healthy Activities Model Program for Seniors (CHAMPS) is a physical activity monitoring questionnaire for people between 65 to 90 years old. This questionnaire has been previously translated to Spanish to be used in the Latin American population. To adapt the Spanish version of the CHAMPS questionnaire to Puerto Rico and assess its internal consistency. An external review committee adapted the existent Spanish version of the CHAMPS to be used in the Puerto Rican population. Three older adults participated in a second phase with the purpose of training the research team. After the second phase, 35 older adults participated in a third content adaptation phase. During the third phase, the preliminary Spanish version for Puerto Rico of the CHAMPS was given to the 35 participants to assess for clarity, vocabulary and understandability. Interviews to each participant in the third phase were carried out to obtain feedback and create a final Spanish version of the CHAMPS for Puerto Rico. After analyses of this phase, the external review committee prepared a final Spanish version of the CHAMPS for Puerto Rico. The final version was administered to 15 older adults (76 +/- 6.5 years) to assess the internal consistency by using Cronbach's Alpha analysis. The questionnaire showed a strong internal consistency of 0.76. The total time to answer the questionnaire was 17.4 minutes. The Spanish version of the CHAMPS questionnaire for Puerto Rico suggested being an easy to administer and consistent measurement tool to assess physical activity in older adults.

There is a renewed interest in incorporating personality variables in criminology theories in order to build models able to integrate personality variables and biological factors with psychosocial and sociocultural factors. The aim of this article is the assessment of personality dimensions that contribute to the prediction of antisocial behavior in adolescents. For this purpose, a sample of adolescents from El Salvador, Mexico, and Spain was obtained. The sample consisted of 1035 participants with a mean age of 16.2. There were 450 adolescents from a forensic population (those who committed a crime) and 585 adolescents from the normal population (no crime committed). All of participants answered personality tests about neuroticism, extraversion, psychoticism, sensation seeking, impulsivity, and violence risk. Principal component analysis of the data identified two independent factors: (i) the disinhibited behavior pattern (PDC), formed by the dimensions of neuroticism, psychoticism, impulsivity and risk of violence; and (ii) the extrovert behavior pattern (PEC), formed by the dimensions of sensation risk and extraversion. Both patterns significantly contributed to the prediction of adolescent antisocial behavior in a logistic regression model which properly classifies a global percentage of 81.9%, 86.8% for non-offense and 72.5% for offense behavior. The classification power of regression equations allows making very satisfactory predictions about adolescent offense commission. Educational level has been classified as a protective factor, while age and gender (male) have been classified as risk factors.

Ecological resources are resources that have functional value to ecosystems. Frequently, these functions are overlooked in terms of the value they provide to humans. Environmental economics is in search of an appropriate analysis framework for such resources. In such a framework, it is essential to distinguish between two related subsets of information: (1) ecological processes that have intrinsic value to natural ecosystems; and (2) ecological functions that are values by humans. The present study addresses these concerns by identifying a habitat that is being displaced by development, and by measuring the human and ecological values associated with the ecological resources in that habitat. It is also essential to determine which functions are mutually exclusive and which are, in effect, complementary or products of joint production. The authors apply several resource valuation tools, including contingent valuation methodology (CVM), travel cost methodology (TCM), and hedonic damage-pricing (HDP). One way to derive upper-limit values for more difficult-to-value functions is through the use of human analogs, because human-engineered systems are relatively inefficient at supplying the desired services when compared with natural systems. Where data on the relative efficiencies of natural systems and human analogs exist, it is possible to adjust the costs of providing the human analog by the relative efficiency of the natural system to obtain a more realistic value of the function under consideration. The authors demonstrate this approach in an environmental economic case study of the environmental services rendered by shrub-steppe habitats of Benton County, Washington State.
Using facts and examples, this didactically structures textbook gives an insight into the extent and consequences of the damage to the environment, with the subjects - fundamentals of ecology; - population and food problems; - the energy problem; - economic growth; scarcity of resources, recycling; - ground, water, and air pollution, - city and traffic problems; - work protection and medical care; - political alternatives and 'soft technologies'. The analysis of the political and economic reasons is combined with social and technical alternatives from which demands to be made and measures to be taken can be derived for individuals, citizens' interest groups, political groups and trade unions. Teaching models intend to help teachers to work on specific problems of ecology. (orig.) [de

The main effort of the Terrestrial Ecology Division has been redirected to a comprehensive study of the Espiritu Santo Drainage Basin located in northeastern Puerto Rico. The general objective are to provide baseline ecological data for future environmental assessment studies at the local and regional levels, and to provide through an ecosystem approach data for the development of management alternatives for the wise utilization of energy, water, and land resources. The interrelationships among climate, vegetation, soils, and man, and their combined influence upon the hydrologic cycle will be described and evaluated. Environmental management involves planning and decision making, and both require an adequate data base. At present, little is known about the interworkings of a complete, integrated system such as a drainage basin. A literature survey of the main research areas confirmed that, although many individual ecologically oriented studies have been carried out in a tropical environment, few if any provide the data base required for environmental management. In view of rapidly changing socio-economic conditions and natural resources limitations, management urgently requires data from these systems: physical (climatological), biological, and cultural. This integrated drainage basin study has been designed to provide such data. The scope of this program covers the hydrologic cycle as it is affected by the interactions of the physical, biological, and cultural systems
Margrit Hugentobler advocates a version of urban sustainable development which rests on an appeal to nature or "natural harmony." To do this, we have to have conceptions both of nature and of human society. These conceptions will determine, among other things, the extent to which human societies are to be regarded as part of the natural world. Then we have to have ethical or moral premises to argue that human societies and habitations should imitate or emulate nature. These moral premises are assumed rather than validated in Margrit Hugentobler's critique.
The discussion on the different development paths towards a future energy supply is conducted not only with technical, economic, and ecological arguments but also with political, socio-cultural and philosophical ones. It is also concerned with the construction of social reality, a reorganisation of the relationship between nature and society. This descriptive and analytical study carefully contemplates the contents of the different positions and arguments in the energy controversy. It thereby closes a gap which has continued to exist until now in spite of the numerous publications in point. (orig.) [de

The traditional approach to ecological risk assessment at hazardous waste sites that are being evaluated for cleanup under CERCLA or RCRA requirements is to focus on the immediate impacts at or adjacent to a site. While this may be acceptable in some situations, it is not ecologically defensible in situations where there are numerous contaminated sites in proximity to each other. In the latter case, transport from the sites, potential cumulative effects, and wide-ranging receptors must be considered. The concept of the Ecological Exposure Unit (EEU) has been proposed to address this situation. Ecological Exposure Units are defined on the basis of ecological considerations and each EEU may contain several to many contaminated sites. The initial steps involved in performing ecological risk assessments using the EEU approach include (1) selection of appropriate receptors and assessment endpoints, and (2) geographical definition of EEUs. At Los Alamos National Laboratory, receptors have been identified and EEUs have been defined for these receptors. GIS is being used as a tool to map EEUs. Receptors include representatives from threatened or endangered species, species reflecting status of ecological health, species with social or cultural relevance, and other species of concern. After definition of EEUs, cumulative impacts of all stressors at all sites within each EEU must be evaluated. The two major advantages to performing ecological risk assessments using this approach are that risk assessments are performed in a more scientifically defensible manner because they are performed on ecologically defined units and that resources are used optimally by minimizing redundant remedial activities
The term 'historical ecology' has been used with various meanings since the first half of the 20th century. Studies labelled as historical ecology have been produced in at least four academic disciplines: history, ecology, geography and anthropology. Although all those involved seem to agree that historical ecology concerns the historical interconnectedness of nature and human culture, this field of study has no unified methodology, specialized institutional background and common publication forums. Knowledge of the development of historical ecology is also limited. As a result, the current multitude of definitions of historical ecology is accompanied by divergent opinions as to where the origins of the field are to be sought. In this review, I follow the development of historical ecology from the 18th century to the present. In the first part, I briefly describe some early examples of historical ecological investigations, followed by a description of the various scientific strands in the 20th century that contributed to the formation of historical ecology. In the second part, I discuss the past five decades of historical ecological investigations in more detail, focusing mostly (but not exclusively) on works that their respective authors identified as historical ecology. I also examine the appearance and interconnectedness of the two main trends (ecological and anthropological) in historical ecological research. In the last part, I attempt to outline the future of historical ecology based on common features in existing research. It appears that at present historical ecology is at a crossroads. With rapidly growing interest in historical ecological research, it may move towards institutionalization or remain an umbrella term. © 2014 The Authors.

Full Text Available This essay describes strategic approaches to graphic representation associated with critical environmental engagement and that build from the idea of works of architecture as stitches in the ecological fabric of the city. It focuses on the building up of partial or fragmented graphics in order to describe inclusive, open-ended possibilities for making architecture that marry rich experience and responsive performance. An aphoristic approach to crafting drawings involves complex layering, conscious absence and the embracing of tension. A self-critical attitude toward the generation of imagery characterized by the notion of ‘loose precision’ may lead to more transformative and environmentally responsive architectures.

Industrial ecology addresses issues that will impact future production, use, and disposal technologies; proper use of the concept should reduce significantly the resources devoted to potential remediation in the future. This cradle-to-reincarnation production philosophy includes industrial processes that are environmentally sound and products that are environmentally safe during use and economically recyclable after use without adverse impact on the environment or on the net cost to society. This will require an industry-university-government round table to set the strategy and agenda for progress. PMID:11607254

La costra biológica del suelo: Avances recientes en el conocimiento de su estructura y función ecológica Biological soil crusts: Recent advances in our knowledge of their structure and ecological function
ANDREA P CASTILLO-MONROY
estructura y funcionamiento de los ecosistemas en los que se encuentran.Biological soil crusts (BSCs result from an intimate association between soil particles and cyanobacteria, algae, microfungi, lichens, and bryophytes. These crusts are widespread in many type of soils and in almost all plant communities where sunlight can reach the soil surface. However, BSCs are particulary dominant in environments with low productivity such as arid, semi-arid, alpine and polar areas. Biological soil crusts affect soil nutrient cycling, influence the local hidrological cycle, increase soil stability, and affect the establisment and performance of vascular plants. The knowledge on the biology, ecology and physiology of BSCs has substantially increased in recent years. However, there are important gaps in our knowledge concerning the influence of BSCs on biogeochemical cycles, particularly of phosphorus and carbon, as well as on many aspects related to biotic interactions among BSC components, and between these components and microorganisms, vascular plants and invertebrates. It is necessary to expand current research efforts to other parts of the world, as most studies have been conducted mainly in arid and semi-arid areas of USA, Israel, Australia and China. Of particular concern is the lack of studies from Central and South America, despite BSCs must be a key biotic component in countries such as Chile, Argentina, Peru and Mexico. With the aim of increasing the interest of the scientific community of Spanish-speaking countries about this important group of organisms, in this review we illustrate recent advances on the importance of BSCs to maintain the structure and functioning of those ecosystems in which they are present. We also highlight the main gaps in our knowledge on the ecology of these organisms, and discuss key areas for future research.

Most ecological interactions occur in environments that are spatially and temporally heterogeneous-'patchy'-across a wide range of scales. In contrast, most theoretical models of ecological interactions, especially large-scale models applied to societal issues such as climate change, resource management and human health, are based on 'mean field' approaches in which the underlying patchiness of interacting consumers and resources is intentionally averaged out. Mean field ecological models typically have the advantages of tractability, few parameters and clear interpretation; more technically complex spatially explicit models, which resolve ecological patchiness at some (or all relevant) scales, generally lack these advantages. This report presents a heuristic analysis that incorporates important elements of consumer-resource patchiness with minimal technical complexity. The analysis uses scaling arguments to establish conditions under which key mechanisms-movement, reproduction and consumption-strongly affect consumer-resource interactions in patchy environments. By very general arguments, the relative magnitudes of these three mechanisms are quantified by three non-dimensional ecological indices: the Frost, Strathmann and Lessard numbers. Qualitative analysis based on these ecological indices provides a basis for conjectures concerning the expected characteristics of organisms, species interactions and ecosystems in patchy environments.
Full Text Available Does the trend in which electronic media are gradually becoming extension of human body have to move towards full enslavement of a human and his personality, or the same human will unpredictably, with the aid of his personal media literacy, exit the whirls of media and technological censorships? Personality crisis is closely related to the crisis of language no matter how contradicted to global ideology of transnational transhumanism it may seem. Considering the fact that recent media presentations of the world are based on commercialization of environmentalism, philosophical and aesthetic thought appears as an important subject of ecology. As media mediates, the scenery of civilized living increasingly becomes more appealing even though it derives from commercial and political background. Consequently, the future of humanity depends by large on the philosophy of media. Media have to truly ecologise returning the humanum to its essence making it into the extension of the natural world.

The role of natural selection in promoting reproductive isolation has received substantial renewed interest within the last two decades. As a consequence, the study of ecological speciation has become an extremely productive research area in modern evolutionary biology. Recent innovations in sequencing technologies offer an unprecedented opportunity to study the mechanisms involved in ecological speciation. Genome scans provide significant insights but have some important limitations; efforts are needed to integrate them with other approaches to make full use of the sequencing data deluge. An international conference 'Advances in Ecological Speciation' organized by the University of Porto (Portugal) aimed to review current progress in ecological speciation. Using some of the examples presented at the conference, we highlight the benefits of integrating ecological and genomic data and discuss different mechanisms of parallel evolution. Finally, future avenues of research are suggested to advance our knowledge concerning the role of natural selection in the establishment of reproductive isolation during ecological speciation. © 2013 John Wiley & Sons Ltd.

Men are interested in reducing signs of aging, while maintaining a masculine appearance. A chief concern among men is maintenance of scalp hair. Men are also concerned with reducing under eye bags and dark circles. The concern of feminization is of significant importance. Neuromodulators remain the most common cosmetic procedure performed in men. Men often prefer a reduction in facial rhytids, as opposed to elimination of the lines. Softening facial lines in men is meant to maintain an appearance of wisdom, without appearing fragile. Men also wish to maintain a taut jawline and a slim waist and reduce breast tissue.

After a number of high-profile incidents and national reports, it has become clear that all health professionals and all medical students must be able to raise concerns about a colleague's behavior if this behavior puts patients, colleagues, or themselves at risk.Detailed evidence from medical students about their confidence to raise concerns is limited, together with examples of barriers, which impair their ability to do so. We describe a questionnaire survey of medical students in a single-center, examining self-reported confidence about raising concerns in a number of possible scenarios. Thematic analysis was applied to comments about barriers identified.Although 80% of respondents felt confident to report a patient safety issue, students were less confident around issues of probity, attitude, and conduct. This needs to be addressed to create clear mechanisms to raise concerns, as well as support for students during the process.

Human agency is transforming the planetary processes at unprecedented rates risking damaging essential life-support systems. Climate change, massive species extinction, land degradation, resources depletion, overpopulation, poverty and social injustice are all the result of human choices and non-sustainable ways of life. The survival of our modern economic systems depends upon insatiable consumption - a simple way of life no longer satisfies most people. Detached, instrumental rationality has created an ideal of liberalism based on individual pursuit of self-interest, leading the way into unprecedented material progress but bringing with it human alienation, social injustice, and ecological degradation. The purpose of this presentation is to introduce a community-based systems response to a growing sense that the interlocked social-ecological crisis is as much a problem of human thought and behavior as it is about identifying carrying capacities and CO2 concentrations in the atmosphere. This approach, referred to here as civic ecology, presents a new and important paradigm shift in sustainability practice that attempts to bring together and integrate ecological ideas and postmodern thinking. As such, it is as much a holistic, dynamic, and synergistic approach to ecological sustainability, as it is a philosophy of life and ethical perspective born of ecological understanding and insight. Civic ecology starts with the proposition that the key factor determining the health of the ecosphere is the behavior of human beings, and therefore many of the most important issues related to sustainability lie in the areas of human thought and culture. Thus, the quest for sustainability must include as a central concern the transformation of psychological and behavioral patterns that have become an imminent danger to planetary health. At the core of this understanding is a fundamental paradigm shift from the basic commitments of modern Western culture to its model of mechanism

Research suggests that fairness perceptions matter to people who are asked to evaluate the acceptability of risks or risk management. Two separate national random surveys (n = 305 and n = 529) addressed Americans' concerns about and acceptance of nanotechnology risk management in the context of the degree to which they view scientists and risk managers as fair. The first survey investigated general views about scientists across four proposed dimensions of fairness (distributional, procedural, interpersonal, and informational). The results show that respondents who believe that the outcomes of scientific research tend to result in unequal benefits (distributional fairness) and that the procedures meant to protect the public from scientific research are biased (procedural fairness) were more concerned about nanotechnology. Believing scientists would treat them with respect (interpersonal fairness) and ensure access to information (informational fairness) were not significant predictors of concern. The second study also looked at these four dimensions of fairness but focused on perceptions of risk managers working for government, universities, and major companies. In addition to concern, it also examined acceptance of nanotechnology risk management. Study 2 results were similar to those of study 1 for concern; however, only perceived informational fairness consistently predicted acceptance of nanotechnology risk management. Overall, the study points to the value of considering fairness perceptions in the study of public perceptions of nanotechnology. © 2011 Society for Risk Analysis.
Full Text Available Disease ecology is a new approach to the understanding of the spread and dynamics of pathogens in natural and man-made environments. Defining and describing the ecological niche of the pathogens is one of the major tasks for ecological theory, as well as for practitioners preoccupied with the control and forecasting of established and emerging diseases. Niche theory has been periodically revised, not including in an explicit way the pathogens. However, many progresses have been achieved in niche modeling of disease spread, but few attempts were made to construct a theoretical frame for the ecological niche of pathogens. The paper is a review of the knowledge accumulated during last decades in the niche theory of pathogens and proposes an ecological approach in research. It quest for new control methods in what concerns forest plant pathogens, with a special emphasis on fungi like organisms of the genus Phytophthora. Species of Phytophthora are the most successful plant pathogens of the moment, affecting forest and agricultural systems worldwide, many of them being invasive alien organisms in many ecosystems. The hyperspace of their ecological niche is defined by hosts, environment and human interference, as main axes. To select most important variables within the hyperspace, is important the understanding of the complex role of pathogens in the ecosystems as well as for control programs. Biotic relationships within ecosystem of host-pathogen couple are depicted by ecological network and specific metrics attached to this. The star shaped network is characterized by few high degree nodes, by short path lengths and relatively low connectivity, premises for a rapid disturbance spread.

Population studies were concerned with predicting long-term consequences of mortality imposed on animal populations by man's activities. These studies consisted of development of a generalized life cycle model and an empirical impingement model for use in impact analysis. Chemical effects studies were conducted on chlorine minimization; fouling by the Asiatic clam; identification of halogenated organics in cooling water; and effects of halogenated organics in cooling systems on aquatic organisms. Ecological transport studies were conducted on availability of sediment-bound 137 Cs and 60 Co to fish; 137 Cs and 60 Co in White Oak Lake fish; and chromium levels in fish from a lake chronically contaminated with chromates from cooling towers. Progress is also reported on the following: effects of irradiation on thermal tolerance of mosquito fish; toxicity of nickel to the developing eggs and larvae of carp; accumulation of selected heavy metals associated with fly ash; and environmental monitoring of aquatic ecosystems
Full Text Available The authors examine a very important issue concerning the concept of public consciousness and ecological consciousness of a human. They present ecological consciousness through indicating its level and factors that determine it. They discuss questions connected to shaping ecological consciousness in teachings of Saint John Paul II, sustainable development, eco-philosophy, and pro-ecological attitudes.

learning and media ecologies with the material, global and ecological challenges that have become a part of the anthropocene. They do so by examining the mediation of a physical, architectural environment, their own departmental environment at Simon Fraser University. De Castell, Droumeva and Jenson uncover a range of practical and theoretical challenges, and explore the implications for both body and mind. Markus Deimann takes the reader back into the history of continental educational theory, to Humboldt’s (and others‘ expansive understanding of Bildung, to suggest a conceptual ecology germane to the manifold possibilities that are now on offer through open education. Deimann sees the «open paradigm» as changing education utterly – and for the better. It will do so, Deimann predicts, by «unbundling» resource and service provision, and assessment and accreditation functions that have for too long been monopolized by the educational monoliths known as «universities». Theo Hug’s contribution, «Media Form School – A Plea for Expanded Action Orientations and Reflective Perspectives» similarly looks to the past to envision possibilities for the future. Hug’s concern is with the narrow confines in which media are conceptualized and operationalized in many K-12 educational ecologies, and in the corresponding policy and curricular documents that further constrain and direct this action. Hug suggests looking to the recent past, the 1970s and 1960s, in which alternatives were envisioned not only by figures like McLuhan and Illich, but also intimated in the works of Austrian poets and artists. Norm Friesen provides the third «rearview mirror» perspective in his examination of the lecture as a trans-medial pedagogical form. From the late medieval university through to today’s IGNITE and TED talks, the lecture has accommodated and reflected a wide range of media ecologies, technical conditions and epistemological patterns.

This paper reviews changes in rangeland ecology and management in the U.S.A. over the last 65 years and speculates on future changes. Emphasis has shifted from livestock management to ecological and environmental concerns, hence "rangeland ecology." The term "range management" may have outlived its usefulness and may also be detrimental to our image. The vision that we have of ourselves is not the same as others have of us. Many members of the Society for Range Management (SRM) and most of ou...

Despite the recent fall-out of finance, confidence in the market does not seem to be diminishing, but, on the contrary, market mechanisms are becoming key instruments to deal with core contemporary collective concerns, including global warming, education, environmental pollution, supply of energy......, quality of education, poverty and health care (Mirowski 2013). Recent research within STS has started to focus on such kind of arrangements and in this presentation we will critically engage with this literature. Our main results are twofold. On the one hand, we recognize there are important conceptual...... tools already available - such as 'matters of public concern' (Marres 2007) and 'hybrid forums' (Callon et al. 2001; Callon 2009)- that help in framing the particularity of these arrangements. On the other hand, previous STS-market research notions developed mostly in the field of finance studies cannot...

For the last half decade, regulatory expectations of the procurement process for nuclear commercial-grade safety-related materials have increase. The changes have been driven by concern for fraudulent or misrepresented parts and the loss of original equipment manufacturers. The industry responded to these concerns by developing improved procurement programs that changed how parts were specified and received and provided for verification of attributes that were critical to the successful performance of safety functions(s). Like its counterparts, Duquesne Light Company (DLCo), Beaver Valley power station began applying these enhanced requirements to procurements initiated after January 1, 1990, in response to the Nuclear Management and Resources Council initiative on dedication. Procurements prior to this data were not subject to the new requirements
Martin Heidegger's thought-provoking essay "The Question Concerning Technology" (1977a) placed technology at the heart of philosophy. Heidegger tried to show that the essence of technology provokes humans to think about the world in a very dangerous way. Yet if we follow Heidegger's analysis...... of technology, what role does that ascribe to philosophy? To be able to understand the programmatic scope of Heidegger's question ‘concerning' technology, we need to see it as inseparable from his famous thesis about the end of philosophy (1977c) and what he considers to be the ideal kind of thinking. However......, by doing so, we will in the end realize two important things. First, that Heidegger's declaration of the end of philosophy in fact also means the end of anything we can meaningfully call thinking. Second, that Heidegger's own thinking is completely different from his own ideal of thinking. Our question...

psychology or Kübler-Ross’ theory about death stages. The complex concerns might be explained using Martin Heidegger’s phenomenological thinking. We aimed to illuminate dying patients´ existential concerns about the impending death through a descriptive analysis of semi-structured interviews with 17 cancer...... patients in Danish hospices. The main findings demonstrated how the patients faced the forthcoming death without being anxious of death but sorrowful about leaving life. Furthermore, patients expressed that they avoided thinking about death. However, some had reconstructed specific and positive ideas about...... afterlife and made accurate decisions for practical aspects of their death. The patients wished to focus on positive aspects in their daily life at hospice. It hereby seems important to have ongoing reflections and to include different theoretical perspectives when providing existential support to dying...

We investigate how changes in the commitment power of a principal affect cooperation among agents who work in a team. When the principal and her agents are symmetrically uncertain about the agents' innate abilities, workers have career concerns. Then, unless the principal can commit herself to long-term wage contracts, an implicit sabotage incentive emerges. Agents become reluctant to help their teammates. Anticipating this risk, and in order to induce the desired level of cooperation, the pr...

Full Text Available The issue of probabilities, uncertainties and risks has concerned society since ancient times. By probability we can see the possible realization of an act or event under certain conditions. Uncertainty is caused by emotional status of the decision maker due to more subjective factors or to the knowledge to achieve an objective. Risk is a combination of the two elements characterized by a possible description of probabilities under insecurity uncertainty conditions.

In China, there is an old saying:food is the first necessity of humans. The main concern of the Chinese used to be the security of the food supply rather than the safety of the food itself. However,after a long time fighting food shortages,China became self-sufficient in food in 1995. At this time, the country began for the first time to regulate food safety. Yet China has still not established a legal systern efficient in ensuring this safety. Many problems are rooted in the administration regime and China's priority of economic development.

The anthology takes a humanistic look at coal mining in Illinois. One of its goals is to increase public awareness of coal in American society; it also seeks to enhance understanding of the historical aspects of coal and to study the impact of coal on mining families. Many of the 25 selections in the anthology come from Coal Research Center publications, `Concerning coal` and `Mineral matters`. Articles are arranged in three parts entitled: life in the mining community; mining in folklore, story telling, literature, art and music; and technology as it affected the people of the coal fields. 117 refs., 25 photos. 1 map.
Full Text Available Over past decades a concept of ecological ethics has taken root, which is often equated with environmental ethics. Church and theology have also responded to the environmental crisis. In the last third of the past century an intense discourse about the concerns and extent of a so called creation ethics was conducted. In connection with the question of a creation ethics, and the global responsibility of humans for the biosphere of our planet, the topic of creation has also gained new attention in dogmatics. In this way, ecology has also become a topic of systematic theology. The article focuses on the debate in the German speaking context. Occasionally, a quasi-religious elevation of ecology to the status of a doctrine of salvation is observable. Because theology always also has a function of critique of religion, it must also critically engage the sometimes open and sometimes hidden religious contents and claims of eco-ethical concepts. For this purpose, the first step of the present contribution is to more precisely determine the concepts of creation and nature. Thereafter, the problem of anthropocentrism is analysed. In a further step, the concept of sustainability is analysed. In conclusion, the main features of a responsibility-ethics model of ecological ethics are outlined.

Join the Comité International de Soutien à Adlène Hicheur Since October 8, 2009 our colleague Adlène Hicheur, a French-Algerian physicist working in LHCb has been arrested and then held in a French prison under suspicion of terrorism linked with AQMI. No material proof has been presented, only exchanges of messages on some forum sites suspected of Islamism have been mentioned. Adlène has continuously denied any link with AQMI and lives in a Kafkaesque situation since 14 mois. His lawyer has several times asked for his release and these requests have been turned down. As Adlène’s colleagues, we have been chocked by his arrest and are deeply concerned by the prolongation of his detention for his future in particle physics, even if he will be recognized innocent. Few Concerned-club members and colleagues have created an International committee to support Adlène in his defense presently having 65 members. We invite you t...

Responses to change in the behavior of ecological systems are largely governed by interactions at different levels. Research is essential and is to be necessarily designed to gain insights into various interactions at the community level. Sustainable resource management is only possible if conservation of biodiversity can be accomplished by properly using the knowledge discovered. It is well known that the United States Department of Agriculture provides technical information, resources, and data necessary to assist the researchers in addressing their conservation needs. Conservation aims to protect, preserve and conserve the earth's natural resources. These include, but not limited to the conservation of soil, water, minerals, air, plants and all living beings. The United States Department of Agriculture also encourages farmers and ranchers to voluntarily address threats to soil and water. Protection of wetlands and wildlife habitat has been on the radar screen of conservation experts for a very long time. The main objective has always been to help farmers and landowners conform and comply with federal and state environmental laws. During the implementation phase, farmers should be encouraged to make beneficial, cost-effective changes to methods of irrigation systems. In some cases, the hydrologic regime of the project area can be thought of as principally an issue of river flow regimes for floodplain forests. In this presentation, the author tries to focus on the impact of hydrology and conservation ecology on global warming. He also discusses the impact of hydrology and conservation ecology global air concerns such as greenhouse gas concentrations in the atmosphere. References: Chow, V. T, D. R. Maidment, and L. W.

Values are at the centre of organic farming. The paper examines ethical concerns that are important to consumers, producers and other stakeholders in relation to organic farming practice and how this relates to current standards and the four IFOAM principles of health, ecology, fairness and care. Most concerns can be categorised under four headings but important issues are cross cutting. Currently, standards cover, both directly and indirectly, only a part of ethical values associated with or...
Increased concern about global climate change is leading to an examination of options for reducing the emissions of gases believed to be the principal contributors to the Greenhouse Effect. Carbon dioxide is believed to be the largest contributor to such an effect, and the use of fossil fuels is the largest source of carbon dioxide emissions. geothermal energy is likely to receive increased attention in the years ahead as a way to reduce emissions of CO 2 . Several countries in Asia and the Pacific already have active geothermal programs. The Philippines have the second-largest installed geothermal capacity in the world. Japan and New Zealand have used geothermal energy for several decades. The present and future contributions of geothermal energy to the overall energy supply and reductions in carbon dioxide emissions in Asia and the Pacific are discussed in this paper

The 5th World Conference on Ecological Restoration was held in Madison, Wisconsin, USA on October 6-11, 2013. About 1200 delegates from more than 50 countries attended the conference, and discussed the latest developments in different thematic areas of ecological restoration. Discussions on evaluation of ecological restoration were mainly from three aspects: The construction for evaluation indicator system of ecological restoration; the evaluation methods of ecological restoration; monitoring and dynamic evaluation of ecological restoration. The meeting stressed the importance of evaluation in the process of ecological restoration and concerned the challenges in evaluation of ecological restoration. The conference had the following enlightenments for China' s research on evaluation of ecological restoration: 1) Strengthening the construction of comprehensive evaluation indicators system and focusing on the multi-participation in the evaluation process. 2) Paying more attentions on scale effect and scale transformation in the evaluation process of ecological restoration. 3) Expanding the application of 3S technology in assessing the success of ecological restoration and promoting the dynamic monitoring of ecological restoration. 4) Carrying out international exchanges and cooperation actively, and promoting China's international influence in ecological restoration research.

After a fundamental consideration of the concept of responsibility and 'long-term responsibility' for late sequelae, the problems of an ehtical assessment of risks were illustrated: The concept of risk itself poses three problems - predicting the probability of occurrence, assessing the damage = subjective classification of the degree of damage, determining whether the advantages outweigh the risks. It is not possible to weigh the advantages and risks against each other without assessing the goals and the priorities which have been set. Here ethics is called for, because it concerns itself with the reasonableness of evaluative decisions. Its task is to enable us to become aware of and comprehend our system of values in all of its complexity in reference to real life. Ethics can only fulfill its task if it helps us to adopt an integral perspective, i.e. if it centers on the human being. 'One must assess all technical and economic innovations in terms of whether they are beneficial to the development of mankind on a long-term basis. They are only to be legitimized insofar as they prove themselves to be a means of liberating mankind and contributing to his sense of dignity and identity, as a means of bringing human beings together and encouraging them to care for one another, and as a means of protecting the natural basis of our existence.

Full Text Available Jarosite waste, originating from zinc extraction industry, is considered hazardous due to the presence and the mobility of toxic metals that it contains. Its worldwide disposal in many tailing damps has become a major ecological concern. Three different methods, namely modified Synthetic Precipitation Leaching Procedure (SPLP, three-stage BCR sequential extraction procedure and Potential Ecological Risk Index (PERI Method were used to access the ecological risk of jarosite waste disposal in Mitrovica Industrial Park, Kosovo. The combination of these methods can effectively identify the comprehensive and single pollution levels of heavy metals such as Zn, Pb, Cd, Cu, Ni and As present in jarosite waste. Moreover, the great positive relevance between leaching behavior of heavy metals and F1 fraction was supported by principal component analysis (PCA. PERI results indicate that Cd showed a very high risk class to the environment. The ecological risk of heavy metals declines in the following order: Cd>Zn>Cu>Pb>Ni>As.

In a world of increasing interconnections in global trade as well as rapid change in climate and land cover, the accelerating introduction and spread of invasive species is a critical concern due to associated negative social and ecological impacts, both real and perceived. Much of the societal response to invasive species to date has been associated with negative economic consequences of invasions. This response has shaped a war-like approach to addressing invasions, one with an agenda of eradications and intense ecological restoration efforts towards prior or more desirable ecological regimes. This trajectory often ignores the concept of ecological resilience and associated approaches of resilience-based governance. We argue that the relationship between ecological resilience and invasive species has been understudied to the detriment of attempts to govern invasions, and that most management actions fail, primarily because they do not incorporate adaptive, learning-based approaches. Invasive species can decrease resilience by reducing the biodiversity that underpins ecological functions and processes, making ecosystems more prone to regime shifts. However, invasions do not always result in a shift to an alternative regime; invasions can also increase resilience by introducing novelty, replacing lost ecological functions or adding redundancy that strengthens already existing structures and processes in an ecosystem. This paper examines the potential impacts of species invasions on the resilience of ecosystems and suggests that resilience-based approaches can inform policy by linking the governance of biological invasions to the negotiation of tradeoffs between ecosystem services.

Ecological production functions (EPFs) link ecosystems, stressors, and management actions to ecosystem services (ES) production. Although EPFs are acknowledged as being essential to improve environmental management, their use in ecological risk assessment has received relatively little attention. Ecological production functions may be defined as usable expressions (i.e., models) of the processes by which ecosystems produce ES, often including external influences on those processes. We identify key attributes of EPFs and discuss both actual and idealized examples of their use to inform decision making. Whenever possible, EPFs should estimate final, rather than intermediate, ES. Although various types of EPFs have been developed, we suggest that EPFs are more useful for decision making if they quantify ES outcomes, respond to ecosystem condition, respond to stressor levels or management scenarios, reflect ecological complexity, rely on data with broad coverage, have performed well previously, are practical to use, and are open and transparent. In an example using pesticides, we illustrate how EPFs with these attributes could enable the inclusion of ES in ecological risk assessment. The biggest challenges to ES inclusion are limited data sets that are easily adapted for use in modeling EPFs and generally poor understanding of linkages among ecological components and the processes that ultimately deliver the ES. We conclude by advocating for the incorporation into E

To generate normative data on the Rey-Osterrieth Complex Figure Test (ROCF) across 11 countries in Latin America, with country-specific adjustments for gender, age, and education, where appropriate. The sample consisted of 3,977 healthy adults who were recruited from Argentina, Bolivia, Chile, Cuba, El Salvador, Guatemala, Honduras, Mexico, Paraguay, Peru, and, Puerto Rico. Each subject was administered the ROCF as part of a larger neuropsychological battery. A standardized five-step statistical procedure was used to generate the norms. The final multiple linear regression models explained 7-34% of the variance in ROCF copy scores and 21-41% of the variance in immediate recall scores. Although t-tests showed significant differences between men and women on ROCF copy and immediate recall scores, none of the countries had an effect size larger than 0.3. As a result, gender-adjusted norms were not generated. The present study is the first to create norms for the ROCF in Latin America. As a result, this study will have important implications for the formation and practice of neuropsychology in this region.

Whether the translation of verbal descriptors from English to Spanish affects the validity of the Children's OMNI Scale of Perceived Exertion is not known, so the validity of a Spanish version of the OMNI was examined with 32 boys and 36 girls (9 to 12 years old) for whom Spanish was the primary language. Oxygen consumption, ventilation, respiratory rate, respiratory exchange ratio, heart rate, and ratings of perceived exertion for the overall body (RPE-O) were measured during an incremental treadmill test. All response values displayed significant linear increases across test stages. The linear regression analyses indicated RPE-O values were distributed as positive linear functions of oxygen consumption, ventilation, respiratory rate, respiratory exchange ratio, heart rate, and percent of maximal oxygen consumption. All regression models were statistically significant. The Spanish OMNI Scale is valid for estimating exercise effort during walking and running amongst Hispanic youth whose primary language is Spanish.

Objective To perform translation, cross-cultural adaptation, and validation of the Penn Acoustic Neuroma Quality-of-Life Scale (PANQOL) to the Spanish language. Study Design Prospective study. Setting Tertiary neurotologic referral center. Subjects and Methods PANQOL was translated and translated back, and a pretest trial was performed. The study included 27 individuals diagnosed with vestibular schwannoma. Inclusion criteria were adults with untreated vestibular schwannoma, diagnosed in the past 12 months. Feasibility, internal consistency, test-retest reliability, construct validity, and ceiling and floor effects were assessed for the present study. Results The mean overall score of the PANQOL was 69.21 (0-100 scale, lowest to highest quality of life). Cronbach's α was 0.87. Intraclass correlation coefficient was performed for each item, with an overall score of 0.92. The κ coefficient scores were between moderate and almost perfect in more than 92% of patients. Anxiety and energy domains of the PANQOL were correlated with both physical and mental components of the SF-12. Hearing, balance, and pain domains were correlated with the SF-12 physical component. Facial and general domains were not significantly correlated with any component of the SF-12. Furthermore, the overall score of the PANQOL was correlated with the physical component of the SF-12. Conclusion Feasibility, internal consistency, reliability, and construct validity outcomes in the current study support the validity of the Spanish version of the PANQOL.

As the United States becomes more linguistically and culturally diverse, there is a need for effective health communication interventions that target diverse, vulnerable populations, including Latinos. To address such disparities, health communication interventionists often face the challenge to adapt existing interventions from English into Spanish in a way that retains essential elements of the original intervention while also addressing the linguistic needs and cultural perspectives of the target population. The authors describe the conceptual framework, context, rationale, methods, and findings of a formative research process used in creating a Spanish-language version of an evidence-based (English language) multimedia colorectal cancer screening decision aid. The multistep process included identification of essential elements of the existing intervention, literature review, assessment of the regional context and engagement of key stakeholders, and solicitation of direct input from target population. The authors integrated these findings in the creation of the new adapted intervention. They describe how they used this process to identify and integrate sociocultural themes such as personalism (personalismo), familism (familismo), fear (miedo), embarrassment (verguenza), power distance (respeto), machismo, and trust (confianza) into the Spanish-language decision aid.

Our objective was to perform translation, cross-cultural adaptation and validation of the sino-nasal outcome test 22 (SNOT-22) to Spanish language. SNOT-22 was translated, back translated, and a pretest trial was performed. The study included 119 individuals divided into 60 cases, who met diagnostic criteria for chronic rhinosinusitis according to the European Position Paper on Rhinosinusitis 2012; and 59 controls, who reported no sino-nasal disease. Internal consistency was evaluated with Cronbach's alpha test, reproducibility with Kappa coefficient, reliability with intraclass correlation coefficient (ICC), validity with Mann-Whitney U test and responsiveness with Wilcoxon test. In cases, Cronbach's alpha was 0.91 both before and after treatment, as for controls, it was 0.90 at their first test assessment and 0.88 at 3 weeks. Kappa coefficient was calculated for each item, with an average score of 0.69. ICC was also performed for each item, with a score of 0.87 in the overall score and an average among all items of 0.71. Median score for cases was 47, and 2 for controls, finding the difference to be highly significant (Mann-Whitney U test, p internal consistency, reliability, reproducibility, validity and responsiveness necessary to be a valid instrument to be used in clinical practice.

The attitude toward living kidney donation is important for certain promotion campaigns, however, there are few validated questionnaires in this regard. The aim of this work was to analyze the psychometric characteristics of the attitudes questionnaire about living renal donation, PCID-DVR-Ríos (Cuestionario del Proyecto Colaborativo Internacional Donante sobre Donación de Vivo Renal [Questionnaire of the International Collaborative Donor Project on Living Kidney Donation] developed by Dr Ríos) for the validation of the questionnaire in population of Spanish speakers. The sample studied represented the population >18 years of age, native and resident of Spain, stratified by age and sex. The measurement instrument was the PCID-DVR-Ríos questionnaire. Analysis of data was structured in several stages: an initial description of the data, exploratory factor analysis, item analysis, and internal consistency of the factors. The questionnaire consists of 11 items, distributed in 3 factors of 6, 3, and 2 items. This structure accounts for 63.995% of the total variance. By factors, the variance is distributed as follows: factor 1: 38.461%; factor 2: 14.228%; and factor 3: 11.306%. The analysis of items and internal consistency supported the trifactorial composition. Each factor is internally consistent (α1 = .80; α2 = .70; α3 = .55). The analyzed dimensions of the PCID-DVR Ríos questionnaire to analyze attitude toward living kidney donation showed a good fit in terms of factorial validity and internal consistency values.

The scientific work within the activity ''ecological/biological balances and conservation'' is summarised in this report. The aims of the activity during its existence between 1992 and 1994 have been to: (i) arrange a workshop and publish the presentations on the environmental aspects of energy forest cultivations, (ii) perform joint scientific work together with the activity group on ''biological disposal of wastewaters and sludges'', that is closely related to environmental problems, and (iii) produce ecological guidelines concerning energy forestry, suitable for advisers and farmers dealing with bioenergy problems. The most important results from the workshop were the environmental benefits from energy forestry when compared with intensive agriculture and forestry. Energy forestry has positive influence on the carbon balances, nutrient recycling, and soil sustainability. The effects are also positive on the natural flora and fauna, which in most cases are enriched when compared with agricultural crops. From the joint efforts of the two activities the main result was a study tour, conference and workshop, concentrating on biological purification systems. The most promising system seems to be the vegetation filters of short rotation coppice. The report on ecological guidelines contains a number of ideas and recommendations for establishment, management, and harvesting of energy forests in an environmentally acceptable way. It also gives advice on how to locate the stands to minimise the risk of nutrient leakage from arable land. (Author)

Ecological Economics arise as a scientific discipline aimed to integrate concepts of economics, ecology, thermodynamics, ethic and other natural and social sciences in order to incorporate a biophysical and integrated perspective of the inter dependences between economies and environment, from a plural conception and a methodology beyond disciplines. Ecological Economics studies the black box of economic processes usually excluded of the traditional economics: thermodynamics and ecology. Although it is relatively a new field of study, it has been strengthening its theoretical framework with scientific basis and analytic principles that lead to its identification as a new discipline that show a whole new paradigm. The scope of this article is to show the conceptual and methodological bases, the main founders, approaches and central debates of this new discipline. This brief introduction is a preamble to the papers of the meeting Ecological Economics: a perspective for Colombia included in this number, that took place on September 22 - 27 of 2007, at the National University of Colombia at Bogota. During tree days national and international experts, professors, researchers, workers of environmental sector and people interested on environmental issues joined together to know the conceptual and methodological achievements reached of this discipline; as well as to analyse and evaluate the environmental problems of the country, from the systemic, interdisciplinary and general perspective that it promotes

Highlights: • Concerns and issues in sustainability of CDM forestry projects are reviewed. • Ecological restoration is suggested to be integrated in the CDM framework. • As an ecosystem supporting service, soil restoration on degraded land is of primary importance. • Regenerating forests naturally rather than through monoculture plantations is suggested. • Potential social impacts of ecological restoration are discussed. - Abstract: The Clean Development Mechanism (CDM) is proposed to reduce greenhouse gas emissions and promote sustainable development. CDM forestry projects should contribute to mitigation of climate change through afforestation and reforestation (A/R) activities on degraded land in developing countries. However, like other types of CDM projects, the forestry projects have encountered a number of concerns and critiques. Appropriate approaches and concrete aims to achieve long-term sustainability have been lacking, and reforms have therefore been called for. The aims of this paper are to examine the published information relevant to these concerns, and frame appropriate approaches for a more sustainable CDM. In this review, as a first step to tackle some of these issues, ecological restoration is suggested for integration into the CDM framework. Essentially, this involves the restoration of ecosystem supporting service (soil restoration), upon which forests regenerate naturally rather than establishing monoculture plantations. In this way, forestry projects would bring cost-effective opportunities for multiple ecosystem services. Potential approaches, necessary additions to the monitoring plans, and social impacts of ecological restoration in CDM projects are discussed

We increasingly interact with multiple interactive artifacts with overlapping capabilities during our daily activities. It has previously been shown that the use of an interactive artifact cannot be understood in isolation, but artifacts must be understood as part of an artifact ecology, where...... artifacts influence the use of others. Understanding this interplay becomes more and more essential for interaction design as our artifact ecologies grow. This paper continues a recent discourse on artifact ecologies. Through interviews with iPhone users, we demonstrate that relationships between artifacts...... in artifact ecologies cannot be understood as static, instead they evolve dynamically over time. We provide activity theory-based concepts to explain these dynamics....

Fungi are widespread in nature and have conquered nearly every ecological niche. Fungi occur not only in terrestrial but also in freshwater and marine environments. Moreover, fungi are known as a rich source of secondary metabolites. Despite these facts, the ecological role of many of these metabolites is still unknown and the chemical ecology of fungi has not been investigated systematically so far. This review intends to present examples of the various chemical interactions of fungi with other fungi, plants, bacteria and animals and to give an overview of the current knowledge of fungal chemical ecology.

Introduction: Whether Buddhism has a compelling ecological dimension or not has been a much discussed question in recent years. I think I should put my cards on the table at the outset and say that I count myself among the sceptics in this respect. I see little evidence that the Buddha or his followers, at least down to modern times, have been greatly concerned with questions of ecology. If anything, there is more evidence of a negative presupposition about the value and status of the natural...
Two issues concerning linearity or nonlinearity of natural systems are considered. Each is related to one of the two alternative defining properties of linear systems, superposition and decomposition. Superposition exists when a linear combination of inputs to a system results in the same linear combination of outputs that individually correspond to the original inputs. To demonstrate this property it is necessary that all initial states and inputs of the system which impinge on the output in question be included in the linear combination manipulation. As this is difficult or impossible to do with real systems of any complexity, nature appears nonlinear even though it may be linear. A linear system that displays nonlinear behavior for this reason is termed pseudononlinear. The decomposition property exists when the dynamic response of a system can be partitioned into an input-free portion due to state plus a state-free portion due to input. This is a characteristic of all linear systems, but not of nonlinear systems. Without the decomposition property, it is not possible to distinguish which portions of a system's behavior are due to innate characteristics (self) vs. outside conditions (environment), which is an important class of questions in biology and ecology. Some philosophical aspects of these findings are then considered. It is suggested that those ecologists who hold to the view that organisms and their environments are separate entities are in effect embracing a linear view of nature, even though their belief systems and mathematical models tend to be nonlinear. On the other hand, those who consider that organism-environment complex forms a single inseparable unit are implictly involved in non-linear thought, which may be in conflict with the linear modes and models that some of them use. The need to rectify these ambivalences on the part of both groups is indicated.

Community ecology and paleoecology are both concerned with the composition and structure of biotic assemblages but are largely disconnected. Community ecology focuses on existing species assemblages and recently has begun to integrate history (phylogeny and continental or intercontinental dispersal) to constrain community processes. This division has left a "missing middle": Ecological and environmental processes occurring on timescales from decades to millennia are not yet fully incorporated into community ecology. Quaternary paleoecology has a wealth of data documenting ecological dynamics at these timescales, and both fields can benefit from greater interaction and articulation. We discuss ecological insights revealed by Quaternary terrestrial records, suggest foundations for bridging between the disciplines, and identify topics where the disciplines can engage to mutual benefit.

Human societies, and their well-being, depend to a significant extent on the state of the ecosystems that surround them. These ecosystems are changing rapidly usually in response to anthropogenic changes in the environment. To determine the likely impact of environmental change on ecosystems and the best ways to manage them, it would be desirable to be able to predict their future states. We present a proposal to develop the paradigm of predictive systems ecology, explicitly to understand and predict the properties and behaviour of ecological systems. We discuss the necessary and desirable features of predictive systems ecology models. There are places where predictive systems ecology is already being practised and we summarize a range of terrestrial and marine examples. Significant challenges remain but we suggest that ecology would benefit both as a scientific discipline and increase its impact in society if it were to embrace the need to become more predictive.

The international conference 'Models in population dynamics and ecology 2010: animal movement, dispersal and spatial ecology' took place at the University of Leicester, UK, on 1-3 September 2010, focusing on mathematical approaches to spatial population dynamics and emphasizing cross-scale issues. Exciting new developments in scaling up from individual level movement to descriptions of this movement at the macroscopic level highlighted the importance of mechanistic approaches, with different descriptions at the microscopic level leading to different ecological outcomes. At higher levels of organization, different macroscopic descriptions of movement also led to different properties at the ecosystem and larger scales. New developments from Levy flight descriptions to the incorporation of new methods from physics and elsewhere are revitalizing research in spatial ecology, which will both increase understanding of fundamental ecological processes and lead to tools for better management.

Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term "dental ecology"-defined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context. Copyright © 2012 Wiley Periodicals, Inc.

To describe features of maternal concern for her child undereating; examine maternal and child correlates of maternal concern for undereating; and determine whether maternal concern for undereating is associated with feeding practices. This was a cross-sectional analysis of an observational study with 286 mother-child dyads (mean child age, 71 months). Maternal concern for undereating was assessed using a semistructured interview. Mothers completed questionnaires to assess picky eating, food neophobia, and feeding practices. Feeding practices were further assessed using videotaped mealtime observations. Logistic regression was used to assess the association of maternal and child characteristics with maternal concern for undereating. Regression was used to assess the association of maternal concern for undereating with feeding practices, controlling for covariates. Over a third of mothers (36.5%) expressed concern that their child does not eat enough. Correlates of concern for undereating included child body mass index z-score (BMIz; odds ratio [OR] = 0.58; 95% confidence interval [CI], 0.43-0.77) and picky eating (OR = 2.41; 95% CI, 1.26-4.59). Maternal concern for undereating was associated with greater reported pressure to eat (relative risk [RR] = 1.97; 95% CI, 1.55-2.50), greater observed bribery (OR = 2.63; 95% CI, 1.50-4.60), and higher observed pressure (OR = 1.90; 95% CI, 1.08-3.36) during mealtimes. Mothers of children who are picky eaters and have a lower BMIz are more likely to be concerned that their children do not eat enough, and maternal concern for undereating is associated with pressuring and bribing children to eat. Pediatricians might address maternal concern for undereating by advising feeding practices that do not involve pressure and bribery, particularly among healthy weight children.

Full Text Available We discuss the recent emergence of ‘deliberative ecological economics’, a field that highlights the potential of deliberation for improving environmental governance. We locate the emergence of this literature in the long concern in ecological economics over the policy implications of limited views of human action and its encounter with deliberative democracy scholarship and the model of communicative rationality as an alternative to utilitarianism. Considering criticisms over methods used and the focus of research in deliberative decision-making, we put forward a research agenda for deliberative ecological economics. Given the promising potential of deliberative processes for improving the effectiveness and legitimacy of environmental decision-making, work in this area could help advance both theory and practice in environmental governance.
It is not enough to convey knowledge, insights and attitudes if education in ecology is to have fruitful effects. Space and opportunity for action and creativity must be provided in addition. This includes personal consumer habits (eating, transport, hygiene, leisure activities etc.); an individual workplace - in this case school - that can be shaped according to ecological needs. Beyond this, ecological maturation should not be confined to, but should transcend school, for instance in youth groups, citizens' committees, political parties. If school does not inspire action - including action outside school -then education in ecology could be smothered by the Midas effect, where all life is reduced to material, to the curriculum in this case. This book presents ecological projects that have been tried at schools. They aim at an education in ecology that is oriented to the pupil and open to experience. They could be an incentive for colleagues to conduct similar projects at their schools. The projects work from the pupils' own experience and aim at concrete action and activities in his or her own environment. They should encourage teachers to venture outside the classroom with the pupils and teach ecology where it takes place. (orig.) [de

The ecological principles outlined are very basic ones; the authors anticipate a readership trained in a broad range of disciplines, including those unfamiliar with the academic discipline of ecology. The authors include substantial discussion on ecophysiology (i.e., the responses of organisms to their environment) because this is relevant to the new understanding of the potential climatic consequences of nuclear war. In particular, the physiological sensitivity of organisms to reduced levels of light and temperature are a key part of the analysis of the potential ecological effects and agricultural effects of nuclear war. Much of the ecological analysis has been organized around major biological units called biomes. The authors describe the biome concept and discuss some of the environmental-climatic factors that are believed to control biome distribution. Emphasis is given to plants because of their controlling influence on ecosystem functions through their role as primary producers. Future reports are needed to address more fully the potential effects on animals. Much more research needs to be done on both plant and animal responses to the types of perturbations possible for the aftermath of a nuclear war. Another important element for analysis of the potential ecological consequences of nuclear war concerns recovery processes. As the post-nuclear war environmental extremes ameliorate, ecological communities in devastated regions would begin to reorganize. It is not possible to predict the course of such a succession precisely, but some principles concerning post-perturbation replacement (such as seed banks and germination), relevant successional patterns, and organism strategies are discussed

The ecological interactions that occur in and with soil are of consequence in many ecosystems on the planet. These interactions provide numerous essential ecosystem services, and the sustainable management of soils has attracted increasing scientific and public attention. Although soil ecology emerged as an independent field of research many decades ago, and we have gained important insights into the functioning of soils, there still are fundamental aspects that need to be better understood to ensure that the ecosystem services that soils provide are not lost and that soils can be used in a sustainable way. In this perspectives paper, we highlight some of the major knowledge gaps that should be prioritized in soil ecological research. These research priorities were compiled based on an online survey of 32 editors of Pedobiologia - Journal of Soil Ecology. These editors work at universities and research centers in Europe, North America, Asia, and Australia.The questions were categorized into four themes: (1) soil biodiversity and biogeography, (2) interactions and the functioning of ecosystems, (3) global change and soil management, and (4) new directions. The respondents identified priorities that may be achievable in the near future, as well as several that are currently achievable but remain open. While some of the identified barriers to progress were technological in nature, many respondents cited a need for substantial leadership and goodwill among members of the soil ecology research community, including the need for multi-institutional partnerships, and had substantial concerns regarding the loss of taxonomic expertise.

Transport infrastructure has a wide array of effects on terrestrial and aquatic ecosystems, and road and railway networks are increasingly being associated with a loss of biodiversity worldwide. Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) are two legal frameworks that concern physical planning, with the potential to identify, predict, mitigate and/or compensate transport infrastructure effects with negative impacts on biodiversity. The aim of this study was to review the treatment of ecological impacts in environmental assessment of transport infrastructure plans and projects. A literature review on the topic of EIA, SEA, biodiversity and transport infrastructure was conducted, and 17 problem categories on the treatment of biodiversity were formulated by means of a content analysis. A review of environmental impact statements and environmental reports (EIS/ER) produced between 2005 and 2013 in Sweden and the UK was then conducted using the list of problems as a checklist. The results show that the treatment of ecological impacts has improved substantially over the years, but that some impacts remain problematic; the treatment of fragmentation, the absence of quantitative analysis and that the impact assessment study area was in general delimited without consideration for the scales of ecological processes. Actions to improve the treatment of ecological impacts could include improved guidelines for spatial and temporal delimitation, and the establishment of a quantitative framework including tools, methods and threshold values. Additionally, capacity building and further method development of EIA and SEA friendly spatial ecological models can aid in clarifying the costs as well as the benefits in development/biodiversity tradeoffs. - Highlights: • The treatment of ecological impacts in EIA and SEA has improved. • Quantitative methods for ecological impact assessment were rarely used • Fragmentation effects were recognized

In his respond to critical remarks of Mirkin (2003), the author claims that pluralism in ecology is not only its strength but also a weakness. Contemporary ecology became less pluralistic and this can be considered as good sign of maturing science. Ecological pluralism can be exemplified by the coexistence in 1920-30s of two different approaches to plant community: that of Frederic Clements in USA and that of Josias Braun-Blanquet in France. However the way to progress in this branch of ecology was paved rather by heretical ideas of Henry Gleason in USA and Ramensky in Russia (both authors independently developed non-holistic view of community as an assemblage of individualistically distributed species) than by "peaceful" coexistence of well-established schools, representatives of which tried not to interfere into argumentation of each other. Notable success in ecology of last decades was connected with several new methodologies, e.g. macroecology that concerned large scale of space and time. However Darwinism in its attempt to explain the order of nature referring to its origin remains the most universal and fruitful methodology of ecology. The success of Darwinism in ecology is understandable because this generalizing theory is based on the same universal principles that underlie the survival of any population. Ecologists and evolutionary biologists trying to understand various natural patterns actually deal with the same fundamental laws, i.e. exponential population growth, limitation of this growth by resource shortage and/or press of predators, the existence of individual variability in survival, etc.

Transport infrastructure has a wide array of effects on terrestrial and aquatic ecosystems, and road and railway networks are increasingly being associated with a loss of biodiversity worldwide. Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) are two legal frameworks that concern physical planning, with the potential to identify, predict, mitigate and/or compensate transport infrastructure effects with negative impacts on biodiversity. The aim of this study was to review the treatment of ecological impacts in environmental assessment of transport infrastructure plans and projects. A literature review on the topic of EIA, SEA, biodiversity and transport infrastructure was conducted, and 17 problem categories on the treatment of biodiversity were formulated by means of a content analysis. A review of environmental impact statements and environmental reports (EIS/ER) produced between 2005 and 2013 in Sweden and the UK was then conducted using the list of problems as a checklist. The results show that the treatment of ecological impacts has improved substantially over the years, but that some impacts remain problematic; the treatment of fragmentation, the absence of quantitative analysis and that the impact assessment study area was in general delimited without consideration for the scales of ecological processes. Actions to improve the treatment of ecological impacts could include improved guidelines for spatial and temporal delimitation, and the establishment of a quantitative framework including tools, methods and threshold values. Additionally, capacity building and further method development of EIA and SEA friendly spatial ecological models can aid in clarifying the costs as well as the benefits in development/biodiversity tradeoffs. - Highlights: • The treatment of ecological impacts in EIA and SEA has improved. • Quantitative methods for ecological impact assessment were rarely used • Fragmentation effects were recognized

Full Text Available Rapidly depleted resources with technological and economic developments which increased in recent years has led to deterioration of the natural balance in the world. Urban ecosystems is considerably changed, especially with population growth and intensive construction in the city. This situation, as such in all other areas, urban ecosystems are also increasing their sustainability concerns. More compatible solution with the natural process in landscape design and management have to be brought. This article describes the conceptual structure of ecological park that has become a tool for sustainable urban target in community that matured of environmental awareness. Also planning, design and management principles are explained by supporting with application examples. The obtained results within the framework, it is aimed to create a source for similar applications that will lead to spread in our country. In addition, it is put forward suggestions for dissemination of such practices.

Ecological risk assessment, the process that evaluates the likelihood that adverse ecological effects may occur or are occurring as a result of exposure to one or more stressors, is being developed by the US EPA as a tool for decision making. This book presents one approach to risk assessment-that of applying laboratory toxicity data within an ecosystem model to predict the potential ecological consequences of toxic chemicals. Both Standard Water Column Model (SWACOM), using zooplankton and fish, and Monte Carlo simulations are discussed in detail, along with quantitative explanations for many responses. Simplifying assumptions are explicitly presented. The final chapter discusses strengths, weaknesses, and future directions of the approach. The book is appropriate for anyone who does or uses ecological risk assessment methodologies

Full Text Available The level of marine environmental management is a key factor in the successful implementation of marine power strategies. The improvement in management levels of marine environments requires innovation in marine management. In other words, the transformation of marine environmental management into marine ecological environment management must be done in order to achieve sustainable development of the marine economy. As an environmental economic policy that combines both administrative and market measures, ecological compensation mechanisms have significant advantages in marine ecological environment management. Based on the study of the current development of ecological compensation mechanisms in China, through the analysis of the connotation of marine ecological civilization, existing marine ecological protection practices and marine environmental management methods, this paper posits that the current marine ecological environment management in China should be established on the basis of ecological compensation mechanisms. At present, a lack of laws and regulations for overall marine ecological environment management is the key factor restricting the practice of marine ecological environment management. Therefore, it is necessary to explore the current path of marine ecological environment management in China from the perspective of the construction of legal system of ecological compensation law, the establishment of ecological compensation fees, ecological taxes and ecological compensation fund systems, and the clear status for a marine ecological management and supervision body.

This connection should be articulated around the initial aim of Sraffa: to develop a new paradigm, competing against the neoclassical one. Only then it will be p...

Full Text Available Little urban ecological research has been done in South Africa. The papers in the Ecology and Society special feature Urban Ecological and Social-Ecological Research in the City of Cape Town make, therefore, an important contribution to the development of urban ecology locally and globally. Different approaches have been used in the study of urban ecology of different urban areas in South Africa. Cape Town is situated in a biodiversity hotspot and is the only South African city which includes a national park. As a result the urban ecological studies were mainly driven by urban nature conservation concerns. In other cities such as Durban, open space planning and environmental management were the major issues which focused ecological studies on urban areas whereas other studies of urban areas in the Eastern Cape and North-West provinces included private and public open spaces and man-made habitats. We reflect on the Cape Town studies in a South African context and highlight conservation of biodiversity, protection of ecosystem services, management of control measures, and the conflict between humans and nature. A brief synthesis has also been given of South African urban ecological research in general.

Pakistan is both a country of origin and destination as far as women trafficking is concerned. Poverty, gender discrimination, lack of education, and ignorance about legal rights are some of the underlying causes. Available data suggest several areas of concern, like, for instance: direct health effects, maladaptive coping leading to the use of illicit drugs, and inaccessibility to healthcare facilities. Therefore, numerous interventions would be required at three levels: the prevention of trafficking, the protection of victims and the prosecution of the traffickers.

Traditional ecological studies have been conducted on many sites impacted by hazardous wastes. Yet in many cases, the information obtained has had limited value in the selection of remediation options. This paper discusses the importance of developing an ecological risk-based strategic plan to fulfill the scientific and social needs demanded in the remediation and restoration of hazardous waste sites. Ecological issues need to be considered seriously at the earliest phases of the scoping process. The decisions regarding selection of assessment endpoints and data quality objectives must be incorporated from the start to insure that cost-efficient and useful measurements are used. It is too late to develop effective ecological studies after the engineering decisions have been made. Strategic planning that integrates ecological concerns will minimize the frustration and the cost associated with clean up of hazardous waste sites and maximize the likelihood of successful site restoration

Understanding the interaction among different species within a community and their responses to environmental changes is a central goal in ecology. However, defining the network structure in a microbial community is very challenging due to their extremely high diversity and as-yet uncultivated status. Although recent advance of metagenomic technologies, such as high throughout sequencing and functional gene arrays, provide revolutionary tools for analyzing microbial community structure, it is still difficult to examine network interactions in a microbial community based on high-throughput metagenomics data. Here, we describe a novel mathematical and bioinformatics framework to construct ecological association networks named molecular ecological networks (MENs) through Random Matrix Theory (RMT)-based methods. Compared to other network construction methods, this approach is remarkable in that the network is automatically defined and robust to noise, thus providing excellent solutions to several common issues associated with high-throughput metagenomics data. We applied it to determine the network structure of microbial communities subjected to long-term experimental warming based on pyrosequencing data of 16 S rRNA genes. We showed that the constructed MENs under both warming and unwarming conditions exhibited topological features of scale free, small world and modularity, which were consistent with previously described molecular ecological networks. Eigengene analysis indicated that the eigengenes represented the module profiles relatively well. In consistency with many other studies, several major environmental traits including temperature and soil pH were found to be important in determining network interactions in the microbial communities examined. To facilitate its application by the scientific community, all these methods and statistical tools have been integrated into a comprehensive Molecular Ecological Network Analysis Pipeline (MENAP), which is open

Managers make decisions regarding if and how to remove dams in spite of uncertainty surrounding physical and ecological responses, and stakeholders often raise concerns about certain negative effects, regardless of whether or not these concerns are warranted at a particular site. We used a dam-removal science database supplemented with other information sources to explore seven frequently-raised concerns, herein Common Management Concerns (CMCs). We investigate the occurrence of these concerns and the contributing biophysical controls. The CMCs addressed are: degree and rate of reservoir sediment erosion, excessive channel incision upstream of reservoirs, downstream sediment aggradation, elevated downstream turbidity, drawdown impacts on local water infrastructure, colonization of reservoir sediments by non-native plants, and expansion of invasive fish. Biophysical controls emerged for some of the concerns, providing managers with information to assess whether a given concern is likely to occur at a site. To fully assess CMC risk, managers should concurrently evaluate site conditions and identify the ecosystem or human uses that will be negatively affected if the biophysical phenomenon producing the CMC occurs. We show how many CMCs have one or more controls in common, facilitating the identification of multiple risks at a site, and demonstrate why CMC risks should be considered in the context of other factors like natural watershed variability and disturbance history.
Eco-indices are successfully used for assessment of the ecological state and risks of water reservoirs. They allow, already at early stages, to detect negative effects on water ecosystems caused by progressive anthropogenic impacts and widening of the spectrum of pollutants, and to quantitatively evaluate ecological risks and damage for water reservoirs. Implementing these modern tools to water quality assessment is one of the lines to make decisions concerning challenging environmental problems.

The growth and survival of organisms often depend on interactions between them. In many cases, these interactions are positive and caused by a cooperative modification of the environment. Examples are the cooperative breakdown of complex nutrients in microbes or the construction of elaborate architectures in social insects, in which the individual profits from the collective actions of her peers. However, organisms can similarly display negative interactions by changing the environment in ways that are detrimental for them, for example by resource depletion or the production of toxic byproducts. Here we find an extreme type of negative interactions, in which Paenibacillus sp. bacteria modify the environmental pH to such a degree that it leads to a rapid extinction of the whole population, a phenomenon that we call ecological suicide. Modification of the pH is more pronounced at higher population densities, and thus ecological suicide is more likely to occur with increasing bacterial density. Correspondingly, promoting bacterial growth can drive populations extinct whereas inhibiting bacterial growth by the addition of harmful substances-such as antibiotics-can rescue them. Moreover, ecological suicide can cause oscillatory dynamics, even in single-species populations. We found ecological suicide in a wide variety of microbes, suggesting that it could have an important role in microbial ecology and evolution.
Full Text Available This is a brief survey of Marx and Engels’ views on ecology, from the viewpoint of their relevance for 21th Century ecosocialism. While there are some serious limitations in the way both consider the “development of productive forces”, there are powerfull insights in their discussion of the destructive consequences of capitalist expansion for the environment - an expansion that generates a disastrous metabolic rift in the exchanges between human societies and nature. Some ecological Marxists distinguish between “first stage ecosocialists” - who believe that Marx analyses on ecological issues are too incomplete and dated to be of real relevance today - and “second stage ecosocialists” that emphasize the contemporary methodological significance of Marx’s ecological critique of capitalism. This paper tries to argue for a third position (which probably could be accepted by several people of the two groups above: Marx and Engels discussion on ecological issues is incomplete and dated, but inspite these shortcomings, it has real relevance and methodological significance today.

Critical evaluation of the adequacy of ecological models is urgently needed to enhance their utility in developing theory and enabling environmental managers and policymakers to make informed decisions. Poorly supported management can have detrimental, costly or irreversible impacts on the environment and society. Here, we examine common issues in ecological modelling and suggest criteria for improving modelling frameworks. An appropriate level of process description is crucial to constructing the best possible model, given the available data and understanding of ecological structures. Model details unsupported by data typically lead to over parameterisation and poor model performance. Conversely, a lack of mechanistic details may limit a model's ability to predict ecological systems’ responses to management. Ecological studies that employ models should follow a set of model adequacy assessment protocols that include: asking a series of critical questions regarding state and control variable selection, the determinacy of data, and the sensitivity and validity of analyses. We also need to improve model elaboration, refinement and coarse graining procedures to better understand the relevancy and adequacy of our models and the role they play in advancing theory, improving hind and forecasting, and enabling problem solving and management.

This essay attempts to reconstruct the evolution of Ecology as the scientific basis for environmental conservation and human progress, as seen through the eyes of a biologist who has exercised that science during a number of tasks in various parts of the world over most of the twentieth century. From its beginnings in evolutionary thinking during the nineteenth century, ecology emerged from natural history at the beginning of the twentieth. At first the running was made by botanists; but this was soon followed by zoologists, who dealt with more mobile communities. The first quarter-century was mainly exploratory; the second was mainly descriptive (although biological exploration was still dominant in the tropics). The third quarter saw ecology developing into an experimental science, and, as the environmental revolution got into its stride, ecology became organized both nationally and internationally. Although the term is now often misused and sometimes misunderstood by laymen, the last quarter-century is seeing the wide application of ecology in environmental and human affairs, and this gives some assurance that the twenty-first century will not become one of chaos.
The U.S. Nuclear Regulatory Commission (NRC) published two notices in the Federal Register concerning radioactive waste below regulatory concern. The first, a Commission Policy Statement and Implementation Plan published August 29, 1986, concerns petition to exempt specific radioactive waste streams from the regulations. The second, an Advanced Notice of Proposed Rulemaking published Decemger 2, 1986, addresses the concept of generic rulemaking by the NRC on radioactive wastes that are below regulatory concern. Radioactive waste determined to be below regulatory concern would not be subject to regulatory control and would not need to go to a licensed low-level radioactive waste disposal site. The Policy Statement and Implementation Plan describe (1) the information a petitioner should file in support of a petition to exempt a specific waste stream, (2) the decision criteria the Commission intends to use for judging the petition, and (3) the internal administrative procedures to use be followed in order to permit the Commission to act upon the petition in an expedited manner
Full Text Available Currently world faces the dilemma – ecological economy or economic(al ecology. The researchers produce hundreds of surveys on the topic. However the analyses of recent most cited simulations had shown the diversity of results. Thus, for some states the Kuznets environmental curve has place, for others – no. Same could be said about different years for the same state. It provokes the necessity of drawing new group analyses to reveal the tendencies and relationships between economic and environmental factors. Most flexible and mirror factor of environmental sustainability is the volume of CO2 emissions. The econometric analysis was used for detecting the economic impact on this indicator at the global level and in the spectra of group of states depending on their income. The hypothesis of the existence of environmental Kuznets curve for the analysed data is rejected. Real GDP per capita impact on carbon dioxide emissions is considered only at the global level. The impact of openness of the economy is weak. Rejection happened also to the hypothesis that for the developed countries there is a reverse dependence between the environmental pollution and economic openness. Indicator “energy consumption per capita” impacts on greenhouse gas emissions only in countries with high income. Whereby it should be noted that the more developed a country is, the more elastic is this influence. These results have a potential usage for environmental policy regulation and climate strategy.

Quantitative problems in accomplishing ecological impact assessment with particular reference to defining population effects are discussed with some comments on the two approaches most commonly used, e.g., the experimental and simulation models. Some alternatives are suggested because both methods will probably fail to detect real population effects mostly due to poor understanding of ecosystems or because of the limitations inherent in field census methods. Most judgments of ecological impact are not quantitatively defensible but are qualitative, subjective, or political in nature. An examination of aggregates of data from various nuclear power plant sites may be one way to obtain enough replication to judge ecological impact. Thus, currently available data from such studies as well as appropriate demographic, vegetation, census, and bibliographic material could offer an interesting challenge to computer professionals if such an undertaking were contemplated. Present research programs at PNL and computer involvement are described. Future possibilities and directions are discussed. (U.S.)

This new edition of Numerical Ecology with R guides readers through an applied exploration of the major methods of multivariate data analysis, as seen through the eyes of three ecologists. It provides a bridge between a textbook of numerical ecology and the implementation of this discipline in the R language. The book begins by examining some exploratory approaches. It proceeds logically with the construction of the key building blocks of most methods, i.e. association measures and matrices, and then submits example data to three families of approaches: clustering, ordination and canonical ordination. The last two chapters make use of these methods to explore important and contemporary issues in ecology: the analysis of spatial structures and of community diversity. The aims of methods thus range from descriptive to explanatory and predictive and encompass a wide variety of approaches that should provide readers with an extensive toolbox that can address a wide palette of questions arising in contemporary mul...

The US Fish and Wildlife Service has initiated the production of a comprehensive ecological inventory map series for use as a major new planning tool. Important species data along with special land use designations are displayed on 1:250,000 scale topographic base maps. Sets of maps have been published for the Atlantic and Pacific coastal areas of the United States. Preparation of a map set for the Gulf of Mexico is underway at the present time. Potential application of ecological inventory map series information to a typical land disposal facility could occur during the narrowing of the number of possible disposal sites, the design of potential disposal site studies of ecological resources, the preparation of the environmental report, and the regulatory review of license applications. 3 figures, 3 tables

A post-positivist understanding of ecological science and the call for an "ecological ethic" indicate the need for a radically new approach to evaluating environmental change. The positivist view of science cannot capture the essence of environmental sciences because the recent work of "reflexive" ecological modelers shows that this requires a reconceptualization of the way in which values and ecological models interact in scientific process. Reflexive modelers are ecological modelers who believe it is appropriate for ecologists to examine the motives for their choices in developing models; this self-reflexive approach opens the door to a new way of integrating values into public discourse and to a more comprehensive approach to evaluating ecological change. This reflexive building of ecological models is introduced through the transformative simile of Aldo Leopold, which shows that learning to "think like a mountain" involves a shift in both ecological modeling and in values and responsibility. An adequate, interdisciplinary approach to ecological valuation, requires a re-framing of the evaluation questions in entirely new ways, i.e., a review of the current status of interdisciplinary value theory with respect to ecological values reveals that neither of the widely accepted theories of environmental value-neither economic utilitarianism nor intrinsic value theory (environmental ethics)-provides a foundation for an ecologically sensitive evaluation process. Thus, a new, ecologically sensitive, and more comprehensive approach to evaluating ecological change would include an examination of the metaphors that motivate the models used to describe environmental change.

Why do we self-sacrifice to help others in distress? Two competing theories have emerged, one suggesting that prosocial behavior is primarily motivated by feelings of empathic other-oriented concern, the other that we help mainly because we are egoistically focused on reducing our own discomfort. Here we explore the relationship between costly altruism and these two sub-processes of empathy, specifically drawing on the caregiving model to test the theory that trait empathic concern (e.g. general tendency to have sympathy for another) and trait personal distress (e.g. predisposition to experiencing aversive arousal states) may differentially drive altruistic behavior. We find that trait empathic concern – and not trait personal distress – motivates costly altruism, and this relationship is supported by activity in the ventral tegmental area, caudate and subgenual anterior cingulate, key regions for promoting social attachment and caregiving. Together, this data helps identify the behavioral and neural mechanisms motivating costly altruism, while demonstrating that individual differences in empathic concern-related brain responses can predict real prosocial choice.

Full Text Available As a global consensus continues to form about the gravity of the ecological risks facing the world in the new century, a smaller, parallel consensus about the pivotal role to be played by ecological designers and planners has also emerged. Few observers dispute the basic idea that the physical design of the built environment is a critical element of an ecologically healthy civilisation. As such, the planners and designers who focus on holistic, place-based strategies for creating those environments and promoting the long-term protection of ecosystems have much to contribute to the larger debate over the meaning and practice of sustainability. Because their role is potentially so important, it matters how ecological designers and planners conceptualise and present their work to the larger society. In particular, addressing a subtle, conceptual divide between ecological design and environmental justice concerns should be a priority. Far from being solely the province of New Age escapists or idiosyncratic, wealthy clients as it is often caricatured, ecological design practice is in fact critical to confronting the harsh realities of toxic exposure, air pollution, and water contamination that beset disadvantaged communities. After pointing out the key physical and conceptual links between ecological design and environmental justice, this paper argues that landscape architects do not sufficiently emphasise the human impacts of ecological degradation resulting from unsustainable design. It goes on to identify two specific analytical tools (ecological economics and a modified form of ecological footprint analysis that can help the profession make this case. A greater effort to do so would help to expand the influence of ecological landscape design in both the global debates about sustainability and in localised realms of implementation.

A prototype ecological interface for computer network defense (CND) was developed. Concerns about CND run high. Although there is a vast literature on CND, there is some indication that this research is not being translated into operational contexts. Part of the reason may be that CND has historically been treated as a strictly technical problem, rather than as a socio-technical problem. The cognitive systems engineering (CSE)/ecological interface design (EID) framework was used in the analysis and design of the prototype interface. A brief overview of CSE/EID is provided. EID principles of design (i.e., direct perception, direct manipulation and visual momentum) are described and illustrated through concrete examples from the ecological interface. Key features of the ecological interface include (a) a wide variety of alternative visual displays, (b) controls that allow easy, dynamic reconfiguration of these displays, (c) visual highlighting of functionally related information across displays, (d) control mechanisms to selectively filter massive data sets, and (e) the capability for easy expansion. Cyber attacks from a well-known data set are illustrated through screen shots. CND support needs to be developed with a triadic focus (i.e., humans interacting with technology to accomplish work) if it is to be effective. Iterative design and formal evaluation is also required. The discipline of human factors has a long tradition of success on both counts; it is time that HF became fully involved in CND. Direct application in supporting cyber analysts.

These conditions share common immunopathogenic mechanisms (i.e., the autoimmune tautology), which explain the clinical similarities they have among them as well as their familial clustering (i.e., coaggregation). As part of the autoimmune tautology, the influence of environmental exposure on the risk of developing ADs is paramount (i.e., the autoimmune ecology). In fact, environment, more than genetics, shapes immune system. Autoimmune ecology is akin to exposome, that is all the exposures - internal and external - across the lifespan, interacting with hereditary factors (both genetics and epigenetics) to favor or protect against autoimmunity and its outcomes. Herein, we provide an overview of the autoimmune ecology, focusing on the immune response to environmental agents in general, and microbiota, cigarette smoking, alcohol and coffee consumption, socioeconomic status (SES), gender and sex hormones, vitamin D, organic solvents, and vaccines in particular. Inclusion of the autoimmune ecology in disease etiology and health will improve the way personalized medicine is currently conceived and applied.

Chemical ecology elucidates the nature and role of natural products as mediators of organismal interactions. The emerging techniques that can be summarized under the concept of metabolomics provide new opportunities to study such environmentally relevant signaling molecules. Especially comparative tools in metabolomics enable the identification of compounds that are regulated during interaction situations and that might play a role as e.g. pheromones, allelochemicals or in induced and activated defenses. This approach helps overcoming limitations of traditional bioassay-guided structure elucidation approaches. But the power of metabolomics is not limited to the comparison of metabolic profiles of interacting partners. Especially the link to other -omics techniques helps to unravel not only the compounds in question but the entire biosynthetic and genetic re-wiring, required for an ecological response. This review comprehensively highlights successful applications of metabolomics in chemical ecology and discusses existing limitations of these novel techniques. It focuses on recent developments in comparative metabolomics and discusses the use of metabolomics in the systems biology of organismal interactions. It also outlines the potential of large metabolomics initiatives for model organisms in the field of chemical ecology.

The medically unexplained complaint is often a symptom of hypochondriacal concerns. Patients with hypochondriasis may be managed with either naive realism or consideration of morbid categorization or via dimensional assessment of illness beliefs and behaviors. Naive realism will foster focus somatization and promote regression as well as lead to needless tests and treatments. Attention to categorical entities such a major depression or anxiety disorders will alert the clinician to comorbid psychiatric disorders that respond to traditional psychiatric treatments. Finally, by assessing the domains of illness behaviors such as disease conviction, beliefs in organic versus psychological causes, and denial, the clinician can document and then confront abnormal cognitive schema that revolve around somatic concerns that are a proxy for psychosocial difficulties.

Full Text Available This article examines the social representations of water in urban cultures of Argentina, placing the subject as a matter of academic and practical interest. Some questions have guided this investigation—What is water for the urban dweller? What are the actions that a citizen is willing to exercise?—A qualitative research was conducted (according to Yin’s case analysis methodology in Gualeguaychú and Buenos Aires. Following the collected data, the authors reconstructed the dominant paradigm in both cities, which was the ecocentric model. However, the acceptance of ecological values and beliefs is not an indicator of the exercise of proecological behavior concerning water. Empirical findings have guided the authors to inquire the degree of relationship between social representations and attributes of Andrew Dobson’s model of ecological citizenship.

Full Text Available What are the equilibrium features of a financial market where a sizeable proportion of traders face reputational concerns? This question is central to our understanding of financial markets, which are increasingly dominated by institutional investors. We construct a model of delegated portfolio management that captures key features of the US mutual fund industry and embed it in an asset pricing framework. We thus provide a formal model of financial equilibrium with career concerned agents. Fund managers differ in their ability to understand market fundamentals, and in every period investors choose a fund. In equilibrium, the presence of career concerns induces uninformed fund managers to churn, i.e., to engage in trading even when they face a negative expected return. Churners act as noise traders and enhance the level of trading volume. The equilibrium relationship between fund return and net fund flows displays a skewed shape that is consistent with stylized facts. The robustness of our core results is probed from several angles.

Full Text Available Anthropogenic influence upon environment and its results cause ecological disbalance of a natural system, destroy of biological connection between a human being and nature. That’s why it’s necessary to protect environment from pollution. To realize this task we have to involve some economical sciences as well. Consequently, our researches are directed to the determination of the place of ecological marketing so that an enterprise could reach the principles of the concept of steady development through the harmonization of interests of producers of goods concerning to the receiving of desirable income amount, consumers concerning to satisfaction of their needs and a society as a whole about reaching a steady development. The article determines the tasks of ecological marketing as an instrument for providing the realization of principles of the steady development concept paying special attention to its constituents such as economical, ecological, and social. The author determines the advantages of implementation of the ecological marketing which allows to get definite competitive advantages at the market and create a positive image of its trade mark and its produce among customers. It is proved that the maximum synthesis of interests of economics and ecology is one of the ways of biosphere protection and reaching a steady development of all the countries and a society as a whole.

Film radiography may be perceived as technology with environmental concerns, involving the application of chemicals and the discharge of drained waters with high silver levels. Ecological legislation concerning silver content of the wash water differs from country to country. GE Inspection Technologies now offers industrial radiographers several ways to address regulatory limits silver in drained waters. First, two brand new film processors, the Agfa NDT Si and M eco, are introduced to the NDT market. Both machines are equipped with Cascade Fixing Technology, which reduces silver content in the wash water and increases the ability to comply with stricter discharge standards. Next the new eco Film System is presented. This system is based on the new machines, specially adapted films and carefully developed new chemicals. Eco stands for ecological and economic performance. The customer can now process films in a very short cycle, saving money while increasing its ability to comply with environmental limits on discharges of silver into drained waters. This paper will also address other means to reduce the silver freight in the wash water. Opportunities but most of all issues involved in the application of these technologies will be highlighted. Thus the presenter of this paper will demonstrate how film radiography responds to environmental concerns without causing extra financial burdens for the user. (author)

Neuropsychoanalysis explores experimentally and theoretically the philosophically ancient discussion of the relation of mind and body, and seems well placed to overcome the problem of a "mindless" neuroscience and a "brainless" psychology and psychotherapy, especially when combined with a greater awareness that the body itself, not only the brain, provides the material substrate for the emergent phenomenon we call mind. However, the mind-brain-body is itself situated within a complex ecological world, interacting with other mind-brain-bodies and the "non-human environment." This occurs both synchronically and diachronically as the organism and its environment (living and non-living) interact in highly complex often non-linear ways. Psychoanalysis can do much to help unmask the anxieties, deficits, conflicts, phantasies, and defenses crucial in understanding the human dimension of the ecological crisis. Yet, psychoanalysis still largely remains not only a "psychology without biology," which neuropsychoanalysis seeks to remedy, but also a "psychology without ecology." Ecopsychoanalysis (Dodds, 2011b; Dodds and Jordan, 2012) is a new transdisciplinary approach drawing on a range of fields such as psychoanalysis, psychology, ecology, philosophy, science, complexity theory, esthetics, and the humanities. It attempts to play with what each approach has to offer in the sense of a heterogeneous assemblage of ideas and processes, mirroring the interlocking complexity, chaos, and turbulence of nature itself. By emphasizing the way the mind-brain-body studied by neuropsychoanalysis is embedded in wider social and ecological networks, ecopsychoanalysis can help open up the relevance of neuropsychoanalysis to wider fields of study, including those who are concerned with what Wilson (2003) called "the future of life."

Goals of COGEMA's advertising campaign concerning nuclear fuel recycling are to: speak out in an area where COGEMA has legitimacy and is expected; and to take part in the discussion to support and defend an activity that is important for COGEMA. Targets are: back up opinion relays by reaching the general public; and back COGEMA personnel. The advertising strategy can be defined as follows: what is recommended for other industries (sorting and then recycling) is COGEMA's practice for spent fuel, with very significant advantages for the community in terms of economy and ecology

Basic research on biodiversity has concentrated on individual species-naming new species, studying distribution patterns, and analyzing their evolutionary relationships. Yet biodiversity is more than a collection of individual species; it is the combination of biological entities and processes that support life on Earth. To understand biodiversity we must catalog it, but we must also assess the ways species interact with other species to provide functional support for the Tree of Life. Ecological interactions may be lost well before the species involved in those interactions go extinct; their ecological functions disappear even though they remain. Here, I address the challenges in studying the functional aspects of species interactions and how basic research is helping us address the fast-paced extinction of species due to human activities.

The US Ecology computer data system was instituted March 1, 1982. This system was designed to manage the increasing flow of paperwork and data associated with the receipt and disposal of low-level radioactive waste at Richland, Washington and Beatty, Nevada. The system was modified and upgraded in 1984 to accommodate a revised shipping manifest pursuant to the requirements of 10 CFR 20.311. The data system is used to generate various reports for both internal and external distribution. The computer system is located at US Ecology's corporate headquarters in Louisville, Kentucky. Remote access terminals are located at the disposal sites. The system is supported by a Wang VS-100 processor. In addition to supporting the radwaste data system, the system supports a chemical waste data base, word processing, and electronic mail. The management and operation of this data base are described. 19 figures

The primary reasons for conducting fundamental research are satisfying curiosity, acquiring knowledge, and achieving understanding. Here we develop why we believe it is essential to promote basic ecological research, despite increased impetus for ecologists to conduct and present their research in the light of potential applications. This includes the understanding of our environment, for intellectual, economical, social, and political reasons, and as a major source of innovation. We contend that we should focus less on short-term, objective-driven research and more on creativity and exploratory analyses, quantitatively estimate the benefits of fundamental research for society, and better explain the nature and importance of fundamental ecology to students, politicians, decision makers, and the general public. Our perspective and underlying arguments should also apply to evolutionary biology and to many of the other biological and physical sciences. Copyright © 2014 The Authors. Published by Elsevier Ltd..

Full Text Available I should like to submit to you a simple, basic thesis--that what we are accustomed to calling the "ecological crisis" is not a product of a conflict between human needs and the needs of nature but of a flawed perception of what our needs in truth are. It is, I believe, a crisis of our humanity rather than one of nature or technology, and so requires not only technological but also humanistic answers.
In this chapter of the book author deals with the ecological aspects of the Gabcikovo-Nagymaros Project (GNP) as well as other projects on the European rivers.

Chemical and radioactive contamination, as well as their synergistic effects are discussed
Owing to the very restrictive information policy of the socialist governments, little is known of the ecological situation in these countries. Attention has been drawn to their ecological problems by a number of accidents (Chernobyl, forest decline along the western frontier of East Germany and Czechoslovakia, pollution of the Elbe river, smog situations in West Germany). Of the Western nations, West Germany is the most concerned as it borders on East Germany and Czechoslovakia. The book intends to help close the information gap concerning ecological problems and environmental policy in the socialist countries. It comprises three sections: Part 1 presents central characteristics of environmental policy in the socialist states, with a view to their specific ideological and administrative aspects. Part 2 compares selected fields of environmental policy in the different socialist countries. Part 3 presents case studies of some countries in Central and Eastern Europe. (orig./HP) [de

Natural toxins such as mycotoxins or phytotoxins (bioactive compounds from fungi and plants, respectively) have been widely studied in food and feed, where they are stated to out-compete synthetic chemicals in their overall human and animal toxicological risk. A similar perception and awareness is yet largely missing for environmental safety. This article attempts to raise concern in this regard, by providing (circumstantial) evidence that phytotoxins in particular can be emitted into the environment, where they may contribute to the complex mixture of organic micropollutants. Exposures can be orders-of-magnitude higher in anthropogenically managed/affected (agro-)ecosystems than in the pristine environment.
Full Text Available The paper explores the strategic role that urban biodiversity and ecosystem services management, natural infrastructure and adaptive governance approaches can play in making our economies and societies more resilient and in linking human societies and the natural environment. Resilience – a concept that entered the debate on urban governance – means the ability of urban systems, considered as linear-systems, to react to external disturbances by returning to some socio-ecological equilibrium steady-state by overcoming a crisis period (Gunderson & al. 2010, Newman & al. 2009. In this view, green infrastructures can assume a strategic role in restoring and enhancing the ecological and environmental livability in urban areas. Starting from the International and European context, the paper discusses innovative programs and interdisciplinary projects and practices (some cases in Turin Metropolitan Area to demonstrate how green infrastructures can increase the adaptive capacity of urban systems in term of resilience. They can contribute to increase the ability of European cities to adapt to climate change and to reduce their ecological footprints, to enhance security and life quality.
Full Text Available This paper outlines a synthesis of ecological economics with econophysics and other complexity approaches to economics. Arguably, the resulting “ecological econophysics” will be scientifically sounder than mainstream economics and much better suited to addressing a major challenge of our times: the development of democratically-based policies to reduce economic throughput to an environmentally sustainable level without triggering economic crises and without excluding part of the world’s population, i.e., to implement degrowth. Degrowth will need major structural changes, which leads us to question whether there are limits to the malleability of the economic system’s architecture. A fundamental limit will be encountered if, as suggested by the physics of complexity, long-lasting complex systems always occur midway between an ordered and a disordered state. There is much evidence that this hypothesis holds and that the current economic system satisfies this condition. However, this does not mean that the problems posed by this system should be unavoidable. Ecological econophysics gives clues to identifying alternative economic systems that would also function between order and chaos, but which would have radically different implications for environmental sustainability and social justice.

To forecast the ecological impact of global change, research initiatives are needed on the explicit role of humans in ecological systems, and on how ecological processes functioning at different spatial and temporal scales are coupled. Furthermore, to synthesize the results of ecological research for Congress, policymakers, and the general public, a new agency, called the United States Ecological Survey (USES) is urgently required. Also, a national commitment to environmental health, as exemplified by establishing a National Institutes of the Environment (NIE), should be a goal

Recent advances in agricultural biotechnology have highlighted the need for experimental evidence and sound scientific judgment to assess the benefits and risks to society. Nutrition scientists and other animal biologists need a balanced understanding of the issues to participate in this assessment. To date most modifications to crop plants have benefited producers. Crops have been engineered to decrease pesticide and herbicide usage, protect against stressors, enhance yields and extend shelf life. Beyond the environmental benefits of decreased pesticide and herbicide application, consumers stand to benefit by development of food crops with increased nutritional value, medicinal properties, enhanced taste and esthetic appeal. There remains concern that these benefits come with a cost to the environment or increased risk to the consumer. Most U.S. consumers are not aware of the extent that genetically modified foods have entered the marketplace. Consumer awareness of biotechnology seems to have increased over the last decade, yet most consumers remain confused over the science. Concern over the impact on the safety of the food supply remains low in the United States, but is substantially elevated in Europe. Before a genetically engineered crop is introduced into commerce it must pass regulatory scrutiny by as many as four different federal regulatory bodies to ensure a safe food supply and minimize the risk to the environment. Key areas for more research are evaluation of the nutritional benefits of new crops, further investigation of the environmental impact, and development of better techniques to identify and track genetically engineered products.

The desire to predict the consequences of global environmental change has been the driver towards more realistic models embracing the variability and uncertainties inherent in ecology. Statistical ecology has gelled over the past decade as a discipline that moves away from describing patterns towards modelling the ecological processes that generate these patterns. Following the fourth International Statistical Ecology Conference (1–4 July 2014) in Montpellier, France, we analyse current trends in statistical ecology. Important advances in the analysis of individual movement, and in the modelling of population dynamics and species distributions, are made possible by the increasing use of hierarchical and hidden process models.

The desire to predict the consequences of global environmental change has been the driver towards more realistic models embracing the variability and uncertainties inherent in ecology. Statistical ecology has gelled over the past decade as a discipline that moves away from describing patterns towards modelling the ecological processes that generate these patterns. Following the fourth International Statistical Ecology Conference (1-4 July 2014) in Montpellier, France, we analyse current trends in statistical ecology. Important advances in the analysis of individual movement, and in the modelling of population dynamics and species distributions, are made possible by the increasing use of hierarchical and hidden process models. Exciting research perspectives include the development of methods to interpret citizen science data and of efficient, flexible computational algorithms for model fitting. Statistical ecology has come of age: it now provides a general and mathematically rigorous framework linking ecological theory and empirical data.

The eco-construction on regional and landscape scale is the one which can be used to specific landscape and intercrossing ecosystem in specific region including performing scientific administration of ecosystem and optimizing environmental function. Recently, the government has taken a series of significant projects into action, such as national forest protection item, partly forest restoration, and adjustment of water, etc. Enforcing regional eco-construction and maintaining the ecology security of the nation have become the strategic requisition. In various regions, different eco-construction should be applied, for example, performing ecological safeguard measure in ecological sensitive zone, accommodating the ecological load in ecological fragile zone, etc., which can control the activities of human being, so that, sustainable development can be reached. Facing opportunity and challenge in the development of landscape ecology, we have some key topics: landscape pattern of ecological security, land use and ecological process, landscape changes under human activity stress, quantitative evaluation of the influence on human being activities, evaluation of zonal ecological security and advance warning of ecological risk, and planning and optimizing of model in landscape eco-construction.

The Columbia River Comprehensive Impact Assessment (CRCIA) Project at the Pacific Northwest Laboratory (PNL) is evaluating the current human and ecological risks from contaminants in the Columbia River. The risks to be studied are those attributable to past and present activities on the Hanford Site. The Hanford Site is located in southcentral Washington State near the town of Richland. Human risk from exposure to radioactive and hazardous materials will be addressed for a range of river use options. Ecological risk will be evaluated relative to the health of the current river ecosystem. The overall purpose of the project is to determine if enough contamination exists in the Columbia River to warrant cleanup actions under applicable environmental regulations. This report documents an initial review, from a risk perspective, of the wealth of historical data concerning current or potential contamination in the Columbia River. Sampling data were examined for over 600 contaminants. A screening analysis was performed to identify those substances present in such quantities that they may pose a significant human or ecological risk. These substances will require a more detailed analysis to assess their impact on humans or the river ecosystem
Full Text Available In the article analysis of the discrepancies in the production process for selected products in a company producing candles was carried out. Using the Pareto-Lorenzdiagram and the FMEA method the most essential areas having influence on the production of candles were shown. Apart from factors connected with the manufacturing side of the process, factors of the labour organization and requirements concerning the quality of material were also noted. An appropriate quality of equipment constitutes one of the essential conditions of production process functioning and this directly influences manufacturing possibilities of the enterprise. A synthesis of immaterial factors that influence the production of the enterprise, taking into consideration conditions of functioning the production system, was also carried out. The set of factors selected for description was the fourteenth Toyota management principle. Respondents were asked to provide answers which could bring the best improvements.

Full Text Available Nanotechnology deals with the construction of new materials, devices, and different technological systems with a wide range of potential applications at the atomic and molecular level. Nanomaterials have attracted great attention for numerous applications in chemical, biological, and industrial world because of their fascinating physicochemical properties. Nanomaterials and nanodevices are being produced intentionally, unintentionally, and manufactured or engineered by different methods and released into the environment without any safety test. Nantoxicity has become the subject of concern in nanoscience and nanotechnology because of the increasing toxic effects of nanomaterials on the living organisms. Nanomaterials can move freely as compared to the large-sized particles; therefore, they can be more toxic than bulky materials. This review article delineates the toxic effects of different types of nanomaterials on the living organisms through different sources, like water, air, contact with skin, and the methods of determinations of these toxic effects.
Population investment is a major topic in the studies of population and economic relations. In this particular area, numerous theoretical and practical problems are still in need of solution. Concerning the problem of population concept, there are three different approaches: (1) to determine the definition of population investment from the relationship between the population growth and the capital from national income used for investment, including investment in the newly increased population and investment in the entire population; (2) to explain population investment from the economic viewpoint that people are producers; and (3) to explain population investment from the expense needed to change a simple labor force to a skillful labor force. The expenses include educational costs, maintanance spending, wages needed to compensate workers in labor, costs for workers to master and learn modern scientific techniques to be used for production, and the costs of keeping a young labor force in the next generation.

In the last years there has been a growing interest in chilhood obesity in all developed countries. There is a great concern that is prevalence has raised 2-3 fold during the last 20 years. In the spanish chilhood population the obesity prevalence is estimated around 13%. Of note also, a number of other pathologies develop concomitantly with obesity during chilhood. These include type 2 diabetes, a range of respiratory problems, a metabolic syndrome, liver steatosis and seudotumor cerebri among others. Taking for granted that chilhood obesity in its roots is an exogenous disorder, preventive interventions should focus on modifying those ethiologies, improving the ways and nature of chilhood nutrition and its social and ludic behaviours.

The U.S. Department of Energy (DOE) recently initiated a complete review of the DOE High Efficiency Particulate Air (HEPA) Filter Program to identify areas for improvement. Although this process is currently ongoing, various issues and problems have already been identified for action that not only impacts the DOE HEPA filter program, but potentially the national and international air cleaning community as well. This paper briefly reviews a few of those concerns that may be of interest, and discusses actions initiated by the DOE to address the associated issues and problems. Issues discussed include: guidance standards, in-place testing, specifications, Test Facilities, portable units, vacuum cleaners, substitute aerosols, filter efficiencies, aging/shelf life/service life, fire suppression, handbook, Quality Products List (QPL), QA testing, and evaluations.

Climate change is already causing, and is expected to continue to cause, a range of health impacts that vary across different population groups in the United States. The vulnerability of any given group is a function of its sensitivity to climate change related health risks, its exposure to those risks, and its capacity for responding to or coping with climate variability and change. Vulnerable groups of people, described here as populations of concern, include those with low income, some communities of color, immigrant groups (including those with limited English proficiency), Indigenous peoples, children and pregnant women, older adults, vulnerable occupational groups, persons with disabilities, and persons with preexisting or chronic medical conditions. Planners and public health officials, politicians and physicians, scientists and social service providers are tasked with understanding and responding to the health impacts of climate change. Collectively, their characterization of vulnerability should consider how populations of concern experience disproportionate, multiple, and complex risks to their health and well-being in response to climate change. Some groups face a number of stressors related to both climate and non-climate factors. For example, people living in impoverished urban or isolated rural areas, floodplains, coastlines, and other at-risk locations are more vulnerable not only to extreme weather and persistent climate change but also to social and economic stressors. Many of these stressors can occur simultaneously or consecutively. Over time, this “accumulation” of multiple, complex stressors is expected to become more evident1 as climate impacts interact with stressors associated with existing mental and physical health conditions and with other socioeconomic and demographic factors.
The New Brunswick Market Design Committee will address environmental concerns within the context of the new energy policy and market rules for the newly restructured electric power industry. The new rules that come with power restructuring will in some ways facilitate environmental protection but they can also complicate it. With open access markets, it will be possible to coordinate evolving energy frameworks with current environmental objectives. Restructuring provides an opportunity to create incentives and guidelines to operate in an environmentally sustainable manner, as suggested in the New Brunswick Energy Policy, White Paper which outlines green pricing, the development of a provincial Climate Change Action Plan, and promotion of alternative energy. The Market Design Committee examined the environmental concerns listed within the White Paper that pertain to the generation and transmission of electricity. These include the integration of energy and environmental policy. Other issues addressed in this report were trans-boundary and global air emissions, the development of a provincial climate change action plan, and a federal-provincial climate change framework agreement. New Brunswick will encourage the development of pilot studies that demonstrate the benefits of renewable and alternative technologies and that help promote the market to manufacture, sell and maintain renewable and alternative technologies in small-scale on-site power generation. This report also discussed the 4 key air pollutants for which specific treatment has been defined, including sulphur dioxide, nitrogen oxides, mercury and carbon dioxide. Recommendations for reducing these emissions include the use of renewable energy sources, the use of lower carbon fuels, increased efficiency of power transmission/generation/distribution systems, reducing power demand by the industrial sector, and promoting energy efficient building codes. 34 refs., 1 tab
This paper addresses the questions ''Do people think about the environment in similar ways.'', ''What are the similarities and differences across different groups within a country, and what are the similarities and differences across countries.'' Using a new factor-analytical approach (which is described in detail in the appendix) four independent cognitive dimensions of the ecological awareness could be found from a set of 12 Items of the International Environmental Survey of 1980: 1. Attitude toward science and technology; 2. Concern about resources and energy supply; 3. Attitude toward nuclear power; 4. Concern about the limits to growth. The major similarities overall and the minor differences between the countries will be discussed. (orig.) [de
Full Text Available We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their variability, review the interactions between boreal bird populations and disturbance, and describe some tools on how boreal bird populations may be conserved in the future. The boreal system has historically been an area with extensive disturbance such as fire, insect outbreaks, and wind. In addition, the boreal system is vulnerable to global climate change as well as increasing pressure on forest and water resources. Current knowledge indicates that birds play an important role in boreal forests, and sustaining these populations affords many benefits to the health of boreal forests. Many issues must be approached with caution, including the lack of knowledge on our ability to mimic natural disturbance regimes with management, our lack of understanding on fragmentation due to logging activity, which is different from permanent conversion to other land uses such as agriculture or residential area, and our lack of knowledge on what controls variability in boreal bird populations or the linkage between bird population fluctuations and productivity. The essential role that birds can provide is to clarify important ecological concerns and variables that not only will help to sustain bird populations, but also will contribute to the long-term health of the boreal forest for all species, including humans.

The author sketches the critical relation between ecology and basic law - critical in more than one sense. He points out the incompatibility of constitutional states and atomic states which is due to constitutional order being jeopardised by nuclear policy. He traces back the continuously rising awareness of pollution and the modern youth movement to their common root i.e. the awakening, the youth movement of the turn of the century. Eventually, he considers an economical, political, and social decentralization as a feasible alternative which would considerably relieve our basic living conditions from the threatening forms of civilization prevailing.

Using an energy systems language that combines energetics, kinetics, information, cybernetics, and simulation, Ecological and General Systems compares models of many fields of science, helping to derive general systems principles. First published as Systems Ecology in 1983, Ecological and General Systems proposes principles of self-organization and the designs that prevail by maximizing power and efficiency. Comparisons to fifty other systems languages are provided. Innovative presentations are given on earth homeostasis (Gaia); the inadequacy of presenting equations without network relationships and energy constraints; the alternative interpretation of high entropy complexity as adaptive structure; basic equations of ecological economics; and the energy basis of scientific hierarchy.

Microbial ecology is currently undergoing a revolution, with repercussions spreading throughout microbiology, ecology and ecosystem science. The rapid accumulation of molecular data is uncovering vast diversity, abundant uncultivated microbial groups and novel microbial functions. This accumulation of data requires the application of theory to provide organization, structure, mechanistic insight and, ultimately, predictive power that is of practical value, but the application of theory in microbial ecology is currently very limited. Here we argue that the full potential of the ongoing revolution will not be realized if research is not directed and driven by theory, and that the generality of established ecological theory must be tested using microbial systems.

Ecological memory (EM) is defined as the capability of the past states or experiences of a community to influence the present or future ecological responses of the community. As a relatively new concept, EM has received considerable attention in the study of ecosystem structure and function, such as community succession, ecological restoration, biological invasion, and natural resource management. This review summarized the definition, components, and categories of EM, and discussed the possible mechanisms and affecting factors of EM. Also, the potential applications of EM were proposed, in order to further understand the mechanisms of community succession and to guide ecological restoration.

Radionuclides produced by nuclear excavation detonations and released to the environment may enter a variety of biogeochemical cycles and follow essentially the same transfer pathways as their stable-element counterparts. Estimation of potential internal radiation doses to individuals and/or populations living in or near fallout-contaminated areas requires analysis of the food-chain and other ecological pathways by which radionuclides released to the environment may be returned to man. A generalized materials transfer diagram, applicable to the forest, agricultural, freshwater and marine ecosystems providing food and water to the indigenous population of Panama and Colombia in regions that could be affected by nuclear excavation of a sea-level canal between the Atlantic and Pacific Oceans, is presented. Transfer mechanisms effecting the movement of stable elements and radionuclides in terrestrial ecosystems are discussed, and methods used to simulate these processes by means of mathematical models are described to show how intake values are calculated for different radionuclides in the major ecological pathways leading to man. These data provide a basis for estimating potential internal radiation doses for comparison with the radiation protection criteria established by recognized authorities; and this, in turn, provides a basis for recommending measures to insure the radiological safety of the nuclear operation plan.

With the increase of standard of living of the people, the criteria for a comfortable, secure and foremost a healthy manner of living also increase. Thus arise the stressed importance and necessity of more attention for the issues of protection of the environment, for a better life of future generations, as well as for global problems which do not recognize borders. Republic of Macedonia also contributes in this direction within the frame of its possibilities. The creation of the National Ecological Action Plan /NEAP/, is currently being carried out by the Ministry of Construction, Urbanism and Ecology of Republic Macedonia, financed by the World Bank. The most significant part of the material prepared by the author in this project has been presented, also discussed in detail and worked through with the representatives of the World Bank because of the importance of the energy sector for the development of a state. An energy balance of Macedonia until the end of 1995 is presented here, as well as quantities of harmful effluents emitted through these transformations of energy. (author). 24 tabs., 2 ills
Full Text Available The trends of the society for the continuous growth, combined with the demographic changes, today have led to the important ecological problems on a global scale, which include, among others: the increased use of non-renewable natu-ral resources, an increase of the greenhouse gas emissions, contamination of soil, water, air and the progressive degra-dation of ecosystems. In the face of such serious threats the global initiatives of all countries are important to limit the results of the excessive consumption. The aim of the article is to present the methods of measurement of the consump-tion level of natural resources by the societies and the examination of relationships between the level of development of the societies and the use of resources. The popular measure – the ecological footprint – was used as a measurement method for the consumption of the today’s generations in relation to the regenerative possibilities of the natural envi-ronment. On the other hand, as the assessment method for the level of development of societies – the Human Develop-ment Index (HDI, including three basic areas: the life expectancy, GDP level per capita and education was used. The results of the research indicate that the current trend of the unlimited consumption of the highly developed countries takes place at the expense of the future generations.
The dietary life of humans varies with the environment where they live and has been changing with time. It has become possible to examine such changes by using stable carbon and nitrogen isotope composition as a chemical tool. The present report outlines recent developments in the application of this tool and compares the dietary ecologies of various human groups from the viewpoint of isotope geochemistry. The history of the application of this tool to dietary analysis is summarized first, and features of the carbon and nitrogen isotope composition in animals and their relations with the food chain are outlined. The dietary ecology of the current people is then discussed in relation to the isotope composition in food, the isotope composition in hair of the current people, and determination of food habit of specific groups of people from such isotope compositions. For prediction of dietary composition, the report presents a flow chart for an algorism which is based on the Monte Carlo method. It also outlines processes for analyzing food habits of people in the prehistoric age, focusing on distribution of isotope composition in humans over the world. (N.K.)
The benefits and concerns about treating foods with ionizing radiation are reviewed. Radioactivity cannot be induced in foods by treatment with gamma rays from 137 Cs or 60 Co, X-ray sources of 5 MeV or lower energy, or electrons of 10 MeV or lower energy. The evidence supports the safety and efficacy of using ionizing radiation for insect disinfestation of grains; dried spices, vegetables and fruits; and fresh fruit. Species and dose dependent phytotoxic and vitamin changes may occur in some fruits at greater doses than currently approved by the U.S. Food and Drug Administration. Irradiation can inactivate protozoan or helminth parasites and significantly decrease the probability of viable food-borne bacterial pathogens in fish, poultry, and red meats. The titers of amino acids, fatty acids, and vitamins of chicken meat sterilized by thermal, electron-beam, or gamma radiation are presented. On the whole, the data support the safely and efficacy of the process
In this series, the Bulletin aims to explain the role of the Ombuds at CERN by presenting practical examples of misunderstandings that could have been resolved by the Ombuds if he had been contacted earlier. Please note that, in all the situations we present, the names are fictitious and used only to improve clarity. Phil* was a candidate for a position in a different group from the one he had been working for. After his board had taken place, Phil asked for an appointment with the Ombuds. In his opinion, the interview went reasonably well. However Phil had some concerns as he had heard that there was no point in him applying as another candidate will get the position. He had decided to apply anyway, encouraged by other people, with the hope that he would get a good rating that could help him get a position in the future, if he didn't get present one. During the interview he was asked some questions that could only have been answered by candidates with experience related ...

As Mobile Cellular phone ownership grows throughout the developed as well as the developing world, concerns about the health risks due to radio frequency emissions from the mobile phone base stations and due to usage of mobile handsets are slowly growing. This article has a look at the concepts used in the mobile phone technology, the power outputs from base stations and mobile handsets, the quantities Specific Energy Absorption Rate (SAR) and power density as a means to assess the effects on biological tissue. The precautionary approach to manage the health risks from mobile phones by specifying exposure guidelines is explored. Having surveyed the relevant epidemiological surveys and finding them inconclusive, NRPB, United Kingdom's national regulatory body has issued exposure guidelines based on the potential of RF radiation to cause illness or injury through heating of body tissues. USA's Federal Communications Commission (FCC) limits are also listed for comparison. ICNIRP has issued two-tier guidelines, differentiating between occupational and public exposure. The public exposure limits are kept at one-fifth of the occupational exposure limits. The evidence till date, suggests that exposure to RF radiation below NRPB and ICNIRP limits do not cause adverse effects to the general population. However, the gaps in our knowledge warrant a precautionary approach. (author)
Three principles that the U.S. must follow in order to maintain its present way of life are stated: practice of energy conservation; substitution of the more plentiful fuels for the scarce; and development of synthetic fuels and unconventional energy sources. After describing the organizing of the energy agencies and reviewing the history of the nuclear power program in the U.S., the author then discusses the public's concern for nuclear energy which includes radioactive discharges, reactor safety, high-level wastes, and shipment of radioactive materials. He refers to the study by Dr. Norman C. Rasmussen released in 1974, which indicates that the likelihood of a person living in the general vicinity of a reactor being injured in any one year in a reactor accident is one chance in 150 million as compared to his chance of being injured in an automobile accident in that same year as one in 130. On a broader societal viewpoint, if there were 100 reactors operating in the U.S., one individual of the 15 million inhabitants living in the vicinity of these reactors might be killed and two individuals might be injured every 25 years as compared to 1.5 million injuries and 55,000 fatalities in 1974 due to automobile accidents. The author concludes that public acceptance of nuclear power will depend on whether these plants, after a reasonable maturing period, deliver the reliable, economic, and safe power that has been proclaimed

There are many commonly discussed myths about ski safety that are propagated by industry, physicians, and skiers. Through a review of the literature concerning 12 such topics, this article demonstrates that the following are untrue: (1) Broken legs have been traded for blown-out knees. (2) If you know your DIN (a slang term for release indicator value), you can adjust your own bindings. (3) Toe and heel piece settings must be the same to function properly. (4) Formal ski instruction will make you safer. (5) Very short skis do not need release bindings. (6) Spending a lot of money on children's equipment is not worth the cost. (7) Children need plenty of room in ski boots for their growing feet. (8) If you think you are going to fall, just relax. (9) Exercise can prevent skiing injuries. (10) Lower release settings can reduce the risk of anterior cruciate ligament injury. (11) Buying new ski equipment is safer than renting. (12) Skiing is among the most dangerous of activities. It is important for the skiing public, physicians, and all those interested in improving skiing safety to verify the measures they advocate. The statements analyzed here are simply untrue and have the potential to cause harm if taken as fact by those exposed to these unsupported opinions.

The use of spatially explicit models (SEMs) in ecology has grown enormously in the past two decades. One major advancement has been that fine-scale details of landscapes, and of spatially dependent biological processes, such as dispersal and invasion, can now be simulated with great precision, due to improvements in computer technology. Many areas of modeling have shifted toward a focus on capturing these fine-scale details, to improve mechanistic understanding of ecosystems. However, spatially implicit models (SIMs) have played a dominant role in ecology, and arguments have been made that SIMs, which account for the effects of space without specifying spatial positions, have an advantage of being simpler and more broadly applicable, perhaps contributing more to understanding. We address this debate by comparing SEMs and SIMs in examples from the past few decades of modeling research. We argue that, although SIMs have been the dominant approach in the incorporation of space in theoretical ecology, SEMs have unique advantages for addressing pragmatic questions concerning species populations or communities in specific places, because local conditions, such as spatial heterogeneities, organism behaviors, and other contingencies, produce dynamics and patterns that usually cannot be incorporated into simpler SIMs. SEMs are also able to describe mechanisms at the local scale that can create amplifying positive feedbacks at that scale, creating emergent patterns at larger scales, and therefore are important to basic ecological theory. We review the use of SEMs at the level of populations, interacting populations, food webs, and ecosystems and argue that SEMs are not only essential in pragmatic issues, but must play a role in the understanding of causal relationships on landscapes.

Interspecific trait variation has long served as a conceptual foundation for our understanding of ecological patterns and dynamics. In particular, ecologists recognise the important role that animal behaviour plays in shaping ecological processes. An emerging area of interest in animal behaviour, the study of behavioural syndromes (animal personalities) considers how limited behavioural plasticity, as well as behavioural correlations affects an individual's fitness in diverse ecological contexts. In this article we explore how insights from the concept and study of behavioural syndromes provide fresh understanding of major issues in population ecology. We identify several general mechanisms for how population ecology phenomena can be influenced by a species or population's average behavioural type, by within-species variation in behavioural type, or by behavioural correlations across time or across ecological contexts. We note, in particular, the importance of behavioural type-dependent dispersal in spatial ecology. We then review recent literature and provide new syntheses for how these general mechanisms produce novel insights on five major issues in population ecology: (1) limits to species' distribution and abundance; (2) species interactions; (3) population dynamics; (4) relative responses to human-induced rapid environmental change; and (5) ecological invasions. © 2012 Blackwell Publishing Ltd/CNRS.

In ecological networks, natural communities are studied from a complex systems perspective by representing interactions among species within them in the form of a graph, which is in turn analysed using mathematical tools. Topological features encountered in complex networks have been proved to provide the systems they represent with interesting attributes such as robustness and stability, which in ecological systems translates into the ability of communities to resist perturbations of different kinds. A focus of research in community ecology is on understanding the mechanisms by which these complex networks of interactions among species in a community arise. We employ an agent-based approach to model ecological processes operating at the species' interaction level for the study of the emergence of organisation in ecological networks. We have designed protocols of interaction among agents in a multi-agent system based on ecological processes occurring at the interaction level between species in plant-animal mutualistic communities. Interaction models for agents coordination thus engineered facilitate the emergence of network features such as those found in ecological networks of interacting species, in our artificial societies of agents. Agent based models developed in this way facilitate the automation of the design an execution of simulation experiments that allow for the exploration of diverse behavioural mechanisms believed to be responsible for community organisation in ecological communities. This automated way of conducting experiments empowers the study of ecological networks by exploiting the expressive power of interaction models specification in agent systems.

Increased interest in ecological issues such as global climate change, habitat loss, acid deposition, reduced biological diversity, and the ecological impacts of pesticides and toxic chemicals prompts this U.S. Environmental Protection Agency (EPA) report, A Framework for Ecological Risk Assessment ('Framework Report'). The report describes basic elements, or a framework, for evaluating scientific information on the adverse effects of physical and chemical stressors on the environment. The framework offers starting principles and a simple structure as guidance for current ecological risk assessments and as a foundation for future EPA proposals for risk assessment guidelines
Full Text Available The paper presents the concept of the fast fashion and how these lead to an excessive consumption of clothes and as result a growth of the worn products market. The paper also aims to establish how fast fashion is influencing not only the economy also the environment. The fast fashion model can also damage developing economies with a low household income, which are not the necessary most important markets of these companies. Our study has identified the influences in increased purchase behavior and focused especially of the positive relationship between income and clothing expenses. We found out that it is a large gap between the European countries regarding clothing expenses in year and Romania is for far the lowest consumer. It is presented the second hand clothes import-export trade during 2007-2012 and we found out that there is an inverse relation between the balances sheet of import-export of textile products between the developed and developing countries. The authors conclude that the Romania is the largest European importer of second hand clothes but has no large scale recycling. Since collection is done on a voluntary basis it can be confusing for population to know how and where to discard used clothing therefore it is recommended a focus on collection systems of second hand clothes. The methodology used for this paper has mainly been a literature study where both scientific literature, such as scientific articles and reports, and popular science articles have been studied. We also use official information provided from National and International statistical Offices. Academic research on the effects of redirecting used clothing from the waste stream is still in its infancy; however this paper provides some insights into the phenomenon which may add to the emerging literature. .
The author decided to explore legal standards in this paper because they are to only norms but also representations or levels of requirements, excellence or attainment. They thus present a way to look at things, to measure them against others, and to set goals for them. In other words, legal standards, whether in legislation are a part of agency requirements, set goals for getting the job done and then can be used as measures about whether or not it is getting done right. When dealing with the multifaceted problems before us, it is important to put it into perspective. We need to look at it from many points of view but with a stable focus-just as one looks through a microscope or a telescope with different magnifications and fields of vision. To have a point of vie, however, both the experts and the general public need to have some way to judge issues. One way they can do so is to use legal standards

Full Text Available Marine turtles in the western Pacific remain threatened by anthropogenic impacts, but the region lacks long-term biological data for assessing conservation status and trends. The Central West Pacific (CWP population of green turtles (Chelonia mydas was listed as Endangered by the U.S. in 2016, highlighting a need to fill existing data gaps. This study focuses on the subset of this population nesting in the Commonwealth of the Northern Mariana Islands (CNMI. Using 11 years of nesting data, we (i estimate reproductive demographic parameters, (ii quantify abundance and trends, and (iii estimate the impacts of anthropogenic threats, such as poaching of nesting females and increasing sand temperatures. In 2006–2016, nesting beach surveys, identification tagging, and nest excavations were conducted on Saipan, and rapid assessments of nesting activity were conducted on Tinian and Rota. On Saipan, temperature data-loggers were deployed inside nests and evidence of poaching (adults and eggs was recorded. This study documents year-round nesting with a peak in March–July. Nester abundance for the three islands combined was 11.9 ± 5.7 (mean ± standard deviation females annually, with at least 62.8 ± 35.1 nests observed per year. For 39 tagged individuals, straight carapace length was 95.6 ± 4.5 cm, remigration interval was 4.6 ± 1.3 years, and somatic growth was 0.3 ± 0.2 cm/yr. Reproductive parameter estimates included clutch frequency of 7.0 ± 1.3 nests per female, inter-nesting interval of 11.4 ± 1.0 days, clutch size of 93.5 ± 21.4 eggs, incubation period of 56.7 ± 6.4 days, hatching success of 77.9 ± 27.0%, and emergence success of 69.6 ± 30.3%. Mean nest temperature of 30.9 ± 1.5°C was above the pivotal threshold of 29.0°C for temperature dependent sex determination, suggesting a female bias may already exist. Model results suggest (i hatching success decreases and embryonic death increases when nests experience maximum temperatures beyond 34.4°C and 33.8°C, respectively, and (ii embryonic death increases in nests with mean temperatures beyond 31.1°C. On Saipan, 32% of nesters were poached, reducing the annual population growth rate from 11.4 to 7.4%. This study provides the first comprehensive assessment of a nesting green turtle population in the Mariana Archipelago, as well as Micronesia, providing baseline data for the endangered CWP population. Our reproductive demographic data, abundance trends, and anthropogenic threat impact analyses are critical for endangered species management, including assessments of population status and fisheries impacts.
The analytical programme developed by the firm I.B.M. for ECAP electronic circuits, operated initially on the IBM 1620 computer with a certain limitation on the size of the network studied, but already equipped from the conversational angle (type-writer). The IBM 360 computers made it possible to increase the size of the network treated to 50 nodes and 200 branches, but the conversational aspect was suppressed in the ECAP 360 version. With a view to making use of the possibilities of hybrid computers, we have adapted this latter version to the EAI 8400 computer. Without diminishing it in any way, we have modified it so as to provide it with conversational characteristics by using the computers control panel; to give it still further flexibility we have made it possible to record curves during the calculation operation, and to obtain a division of the printed results. To obtain the curves, use was made of analog digital converters of the interface of the hybrid unit EAI 8900 of which the EAI 8400 computer represents the numerical section. The modifications made concern in particular the A.C. analysis and the transient analysis. They facilitate and complete the input of the data; they allow modifications to be made for the calculation of these analyses; they also improve the presentation of the results and facilitate their interpretation. They constitute finally the version ECASAC, i.e. the programme ECAP 360 made conversational by use of a type-writer, with automatic output of the curves. (author) [fr

Full Text Available Given escalating concern worldwide about the loss of biodiversity, and given biodiversity's centrality to quality of life, it is imperative that current ecological knowledge fully informs societal decision making. Over the past two decades, ecological science has undergone many significant shifts in emphasis and perspective, which have important implications for how we manage ecosystems and species. In particular, a shift has occurred from the equilibrium paradigm to one that recognizes the dynamic, non-equilibrium nature of ecosystems. Revised thinking about the spatial and temporal dynamics of ecological systems has important implications for management. Thus, it is of growing concern to ecologists and others that these recent developments have not been translated into information useful to managers and policy makers. Many conservation policies and plans are still based on equilibrium assumptions. A fundamental difficulty with integrating current ecological thinking into biodiversity policy and management planning is that field observations have yet to provide compelling evidence for many of the relationships suggested by non-equilibrium ecology. Yet despite this scientific uncertainty, management and policy decisions must still be made. This paper was motivated by the need for considered scientific debate on the significance of current ideas in theoretical ecology for biodiversity conservation. This paper aims to provide a platform for such discussion by presenting a critical synthesis of recent ecological literature that (1 identifies core issues in ecological theory, and (2 explores the implications of current ecological thinking for biodiversity conservation.

Civic ecology refers to the philosophy and science of community forestry, community gardening, watershed enhancement, and other volunteer-driven restoration practices in cities and elsewhere. Such practices, although often viewed as initiatives to improve a degraded environment, also foster social attributes of resilient social-ecological systems,…
