    The use of heavy metal hyperaccumulating plants has the potential to become a promising new technique to remediate contaminated sites. We investigated the role of metal mobilization in the Cd hyperaccumulation of Thlaspi caerulescens (J. & C. Presl, 'Ganges'). In a micro-lysimeter experiment we investigated the dynamics of Cd concentration of leachate as well as Cd removal by plant uptake in four treatments: (i) Control (bare soil), (ii) T. caerulescens, (iii) nonhyperaccumulator Brassica juncea (L.) Czern. ('PI 426308'), and (iv) co-cropping of the hyperaccumulator and nonhyperaccumulator. The experimental findings were analyzed using one- and two-site rate-limited desorption models. Co-cropping of T. caerulescens and B. juncea did not enhance metal uptake by B. juncea. Although Cd uptake of T. caerulescens was 10 times higher than that of B. juncea, the Cd concentration of leachate of the T. caerulescens treatment did not decrease below that of the B. juncea treatment. The Cd depletion in leachate was well reproduced by the two-site rate-limited desorption model. The optimized desorption coefficient was three orders of magnitude higher in the rhizosphere than in the bulk soil. Our results indicate that T. caerulescens accelerates the resupply of Cd from soil pointing to an important role of kinetic desorption in the hyperaccumulation by T. caerulescens.

  4. Hyperaccumulation of cadmium by hairy roots of Thlaspi caerulescens

    Energy Technology Data Exchange (ETDEWEB)

    Nedelkoska, T.V.; Doran, P.M.

    2000-03-05

    Hairy roots were used to investigate cadmium uptake by Thlaspi caerulescens, a metal hyperaccumulator plant with potential applications in phytoremediation and phytomining. Experiments were carried out in nutrient media under conditions supporting root growth. Accumulation of Cd in short-term (9-h) experiments varied with initial medium pH and increased after treating the roots with H{sup +}-ATPase inhibitor. The highest equilibrium Cd content measured in T. caerulescens roots was 62,800 {micro}g g{sup {minus}1} dry weight, or 6.3% dry weight, at a liquid Cd concentration of 3,710 ppm. Cd levels in live T. caerulescens roots were 1.5- to 1.7-fold those in hairy roots of nonhyperaccumulator species exposed to the same Cd concentration, but similar to the Cd content of auto-claved T. caerulescens roots. The ability to grow at Cd concentrations of up to 100 ppm clearly distinguished T. caerulescens hairy roots from the nonhyperaccumulators. The specific growth rate of T. caerulescens roots was essentially unaffected by 20 to 50 ppm Cd in the culture medium; in contrast, N. tabacum roots turned dark brown at 20 ppm and growth was negligible. Up to 10,600 {micro}g g{sup {minus}1} dry weight Cd was accumulated by growing T. caerulescens hairy roots. Measurement of Cd levels in while roots and in the cell wall fraction revealed significant differences in the responses of T. caerulescens and N. tabacum roots to 20 ppm Cd. Most metal was transported directly into the symplasm of N. tabacum roots within 3 days of exposure; in contrast, T. caerulescens roots stored virtually all of their Cd in the wall fraction for the first 7 to 10 days. This delay in transmembrane uptake may represent an important defensive strategy against Cd poisoning in T. caerulescens, allowing time for activation of intracellular mechanisms for heavy metal detoxification.

    Full Text Available What can street gangs tell us about radicalization and extremist groups? At first glance, these two groups seem to push the boundaries of comparison. In this article, we examine the important similarities and differences across criminal, deviant, and extremist groups. Drawing from research on street gangs, this article explores issues such as levels of explanation,organizational structure, group process, and the increasingly important role of technology and the Internet in the context of radicalization. There are points of convergence across these groups, but it is important to understand the differences between these groups. This review finds little evidence to support the contention that American street gangs are becoming increasingly radicalized. This conclusion is based largely on organizational differences between gangs and terror groups.

    A functional screening in yeast allowed to identify various cDNAs from the Cd/Zn hyper-accumulator Thlaspi caerulescens. TcMT3 displayed high identity with its closest homologue in Arabidopsis thaliana but variation in its Cys residues. Functional analysis in yeast supported a higher binding capacity for Cu, but not for Cd or Zn, of TcMT3 compared to AtMT3. Expression analysis in plants indicated that metallothionein 3 (MT3) like all the other T. caerulescens genes from the screen studied is overexpressed in all studied populations of T. caerulescens compared to A. thaliana. TcMT3 was induced by Cu, but not by Cd. Moreover significant variation in expression within T. caerulescens populations that have contrasting tolerance and accumulation capacities indicated a possible local adaptation of MT3. (orig.)

    The synthesis of phytochelatins (PC) represents a major metal and metalloid detoxification mechanism in various species. PC most likely play a role in the distribution and accumulation of Cd and possibly other metals. However, to date, no studies have investigated the phytochelatin synthase (PCS) genes and their expression in the Cd-hyperaccumulating species. We used functional screens in two yeast species to identify genes expressed by two Cd hyperaccumulators (Arabidopsis halleri and Thlaspi caerulescens) and involved in cellular Cd tolerance. As a result of these screens, PCS genes were identified for both species. PCS1 was in each case the dominating cDNA isolated. The deduced sequences of AhPCS1 and TcPCS1 are very similar to AtPCS1 and their identity is particularly high in the proposed catalytic N-terminal domain. We also identified in A. halleri and T. caerulescens orthologues of AtPCS2 that encode functional PCS. As compared to A. halleri and A. thaliana, T. caerulescens showed the lowest PCS expression. Furthermore, concentrations of PC in Cd-treated roots were the highest in A. thaliana, intermediate in A. halleri and the lowest in T. caerulescens. This mirrors the known capacity of these species to translocate Cd to the shoot, with T. caerulescens being the best translocator. Very low or undetectable concentrations of PC were measured in A. halleri and T. caerulescens shoots, contrary to A. thaliana. These results suggest that extremely efficient alternative Cd sequestration pathways in leaves of Cd hyperaccumulators prevent activation of PC synthase by Cd²⁺ ions.

  3. A comprehensive set of transcript sequences of the heavy metal hyperaccumulator Noccaea caerulescens

    YA-FEN eLIN

    2014-06-01

    Full Text Available Noccaea caerulescens is an extremophile plant species belonging to the Brassicaceae family. It has adapted to grow on soils containing high, normally toxic, concentrations of metals such as nickel, zinc and cadmium. Next to being extremely tolerant to these metals, it is one of the few species known to hyperaccumulate these metals to extremely high concentrations in their aboveground biomass. In order to provide additional molecular resources for this model metal hyperaccumulator species to study and understand the mechanism of heavy metal exposure adaptation, we aimed to provide a comprehensive database of transcript sequences for N. caerulescens. In this study, 23830 transcript sequences (isotigs with an average length of 1025 bps were determined for roots, shoots and inflorescences of N. caerulescens accession ‘Ganges’ by Roche GS-FLEX 454 pyrosequencing. These isotigs were grouped into 20,378 isogroups, representing potential genes. This is a large expansion of the existing N. caerulescens transcriptome set consisting of 3705 unigenes. When compared to a Brassicaceae proteome set, 22,232 (93.2% of the N. caerulescens isotigs (corresponding to 19191 isogroups had a significant match and could be annotated accordingly. Of the remaining sequences, 98 isotigs resembled non-plant sequences and 1386 had no significant similarity to any sequence in the GenBank database. Among the annotated set there were many isotigs with similarity to metal homeostasis genes or genes for glucosinolate biosynthesis. Only for transcripts similar to Metallothionein3 (MT3, clear evidence for an additional copy was found. This comprehensive set of transcripts is expected to further contribute to the discovery of mechanisms used by N. caerulescens to adapt to heavy metal exposure.

    2009-01-01

    Gang activity and membership were noted to be significantly related to financial rewards. As such, gang membership and gang activity should also be understood from an economic perspective. In this article, Pierre Bourdieu's framework of capital is used to analyze two separate samples of Latino and Asian gang members. Stark contrasts in socioeconomic backgrounds are recorded among the two samples of gang members, and gang membership and activities are also noticeably dissimilar. Accessibility to economic, cultural, and social capital is argued to affect gang membership and activities. The results suggest that the availability of legitimate and illegitimate capital greatly affects the trajectory and the length of gang involvement. Also, gangs provide significant material and social capital for the respondents of the study. PMID:19578563

    A limited amount of research examines the short-term consequences of gang membership. Rarer, though, is the examination of more distal consequences of gang membership. This is unfortunate because it understates the true detrimental effect of gang membership across the life course, as well as the effects it may have on children of former gang members. Using data from the Rochester Youth Development Study, this work investigates the impact of gang membership in adolescence (ages 12-18) on a particularly problematic style of parenting, child maltreatment. Using discrete time survival analysis, this study finds that gang membership increases the likelihood of child maltreatment and this relationship is mediated by the more proximal outcomes of gang membership during adolescence, precocious transitions to adulthood.

    2014-06-01

    The aim of this study was to examine whether street gang membership, psychological factors, and social factors such as preprison experiences could predict young offenders' involvement in prison gang activity. Data were collected via individual interviews with 188 young offenders held in a Young Offenders Institution in the United Kingdom. Results showed that psychological factors such as the value individuals attached to social status, a social dominance orientation, and antiauthority attitudes were important in predicting young offenders' involvement in prison gang activity. Further important predictors included preimprisonment events such as levels of threat, levels of individual delinquency, and levels of involvement in group crime. Longer current sentences also predicted involvement in prison gang activity. However, street gang membership was not an important predictor of involvement in prison gang activity. These findings have implications for identifying prisoners involved in prison gang activity and for considering the role of psychological factors and group processes in gang research.

  10. Gang Reengagement Intentions among Incarcerated Serious Juvenile Offenders

    2015-01-01

    Full Text Available Research examining the factors that precipitate gang membership has contributed substantially to our understanding of gangs and gang-related activity, yet we know little about the factors influencing intentions to rejoin a gang after having being incarcerated. This study examines the relationship between gang characteristics, number of incarcerated friends, and family characteristics and gang reengagement intentions, while controlling for ethnicity. Participants were 206 male serious juvenile offenders interviewed as part of the Pathways to Desistance Study. The model explained between 35% and 47% of variance in gang reengagement intentions. However, only three variables made a unique statistically significant contribution to the model (punishment if gang rules are broken, importance of gang membership, and moral disengagement, with the strongest predictor being importance of gang membership. The results suggest that challenging young offenders’ perceptions about the importance of gang membership might be particularly effective in reducing gang reengagement intentions after incarceration.

To explain these facts, we examine a model of criminal gangs and suggest that there is a substitution effect between property crime and violent crime at work. In the model, non-monetary valuation of gang membership is private knowledge. Thus the leaders face a trade-off between less crime per member in large gangs and more crime per member in small gangs.

    Soil microorganisms drive critical functions in plant-soil systems. As such, various microbial properties have been proposed as indicators of soil functioning, making them potentially useful in evaluating the recovery of polluted soils via phytoremediation strategies. To evaluate microbial responses to metal phytoextraction using hyperaccumulators, a microcosm experiment was carried out to study the impacts of Zn and/or Cd pollution and Thlaspi caerulescens growth on key soil microbial properties: basal respiration; substrate-induced respiration (SIR); bacterial community structure as assessed by PCR-denaturing gradient gel electrophoresis (DGGE); community sizes of total bacteria, ammonia-oxidizing bacteria, and chitin-degrading bacteria as assessed by quantitative PCR (Q-PCR); and functional gene distributions as determined by functional gene arrays (GeoChip). T. caerulescens proved to be suitable for Zn and Cd phytoextraction: shoots accumulated up to 8,211 and 1,763 mg kg−1 (dry weight [DW]) of Zn and Cd, respectively. In general, Zn pollution led to decreased levels of basal respiration and ammonia-oxidizing bacteria, while T. caerulescens growth increased the values of substrate-induced respiration (SIR) and total bacteria. In soils polluted with 1,000 mg Zn kg−1 and 250 mg Cd kg−1 (DW), soil bacterial community profiles and the distribution of microbial functional genes were most affected by the presence of metals. Metal-polluted and planted soils had the highest percentage of unique genes detected via the GeoChip (35%). It was possible to track microbial responses to planting with T. caerulescens and to gain insight into the effects of metal pollution on soilborne microbial communities. PMID:20935131

    Youth gang violence has continued its upward trend nationwide. It was once thought that gangs convened only in selected areas, which left churches, schools, and hospitals as "neutral" territory. Unfortunately, this is a fallacy. The results of gang violence pour into hospitals and into intensive care units regularly. The media portrays California as having a gang violence problem; however, throughout the United States, gang violence has risen more than 35% in the past year. Youth gang violence continues to rise dramatically with more and more of our youth deciding to join gangs each day. Sadly, every state has gangs, and the problem is getting much worse in areas that would never have thought about gangs a year ago. These "new generation" of gang members is younger, much more violent, and staying in the gang longer. Gangs are not just an urban problem. Gang activity is a suburban and rural problem too. There are more than 25 500 gangs in the United States, with a total gang membership of 850 000. Ninety-four percent of gang members are male and 6% are female. The ethnic composition nationwide includes 47% Latino, 31% African American, 13% White, 7% Asian, and 2% "mixed," according to the Office of Juvenile Justice and Delinquency Prevention of the U.S. Department of Justice. As a result of the ongoing proliferation of youth street gangs in our communities, it is imperative that critical care nurses and others involved with the direct care become educated about how to identify gang members, their activities, and understand their motivations. Such education and knowledge will help provide solutions to families and the youth themselves, help eradicate the problem of gang violence, and keep health care professionals safe.

    2014-06-01

    Researchers have examined the predictors of adolescent gang membership, finding significant factors in the neighborhood, family, school, peers, and individual domains. However, little is known about whether risk and protective factors differ in predictive salience at different developmental periods. The present study examines predictors of joining a gang, tests whether these factors have different effects at different ages, and whether they differ by gender using the Seattle Social Development Project (SSDP) sample (n=808). By age 19, 173 participants had joined a gang. Using survival analysis, results showed that unique predictors of gang membership onset included living with a gang member, antisocial neighborhood, and antisocial peer influences in the previous year. No time or gender interactions with predictors were statistically significant.

  8. Isolation and identification of 4-α-rhamnosyloxy benzyl glucosinolate in Noccaea caerulescens showing intraspecific variation.

    Glucosinolates are secondary plant compounds typically found in members of the Brassicaceae and a few other plant families. Usually each plant species contains a specific subset of the ∼ 130 different glucosinolates identified to date. However, intraspecific variation in glucosinolate profiles is commonly found. Sinalbin (4-hydroxybenzyl glucosinolate) so far has been identified as the main glucosinolate of the heavy metal accumulating plant species Noccaea caerulescens (Brassicaceae). However, a screening of 13 N. caerulescens populations revealed that in 10 populations a structurally related glucosinolate was found as the major component. Based on nuclear magnetic resonance (NMR) and mass spectrometry analyses of the intact glucosinolate as well as of the products formed after enzymatic conversion by sulfatase or myrosinase, this compound was identified as 4-α-rhamnosyloxy benzyl glucosinolate (glucomoringin). So far, glucomoringin had only been reported as the main glucosinolate of Moringa spp. (Moringaceae) which are tropical tree species. There was no apparent relation between the level of soil pollution at the location of origin, and the presence of glucomoringin. The isothiocyanate that is formed after conversion of glucomoringin is a potent antimicrobial and antitumor agent. It has yet to be established whether glucomoringin or its breakdown product have an added benefit to the plant in its natural habitat.

    Full Text Available OBJETIVO: Relatar o isolamento do vírus Ilheus no Estado de São Paulo e avaliar o seu impacto para a saúde pública. MÉTODOS: O isolamento de vírus foi realizado em camundongos albinos Swiss, a partir de sangue de aves silvestres, capturadas com redes de espera tipo mist net, armadas no nível do solo, no Parque Ecológico do Tietê, São Paulo. A identificação das cepas isoladas foi feita pelos testes de inibição da hemaglutinação, fixação de complemento e neutralização em camundongos. Amostras de plasma de aves e de mamíferos silvestres foram submetidas à pesquisa sorológica para detecção de anticorpos inibidores de hemaglutinação. RESULTADOS: Foram isoladas duas cepas do vírus Ilheus em sangue de aves das espécies Sporophila caerulescens e Molothrus bonariensis e detectados anticorpos em aves das espécies Columbina talpacoti, Geopelia cuneata, Molothrus bonariensis e Sicalis flaveola, em sagüis das espécies Callithrix jacchus e Callithrix penicillata e no quati Nasua nasua. CONCLUSÕES: O isolamento do vírus Ilheus e a detecção de anticorpos específicos em aves residentes, migratórias e de cativeiro, em sagüis e quatis, comprovam a presença desse agente no Parque Ecológico do Tietê. O comportamento migratório de aves silvestres pode determinar a introdução do vírus em outras regiões. Considerando-se a patogenicidade para o homem e a confirmação da circulação desse agente viral em área urbana, freqüentada para atividade de lazer e de educação, o risco de ocorrência de infecção na população humana não pode ser descartado.OBJECTIVE: To report the first Ilheus arboviruses isolated from wild birds and analyze its public health impact.

    We describe a gang violence intervention and define targets for prevention. At-risk youths were identified through courts, public schools, and law enforcement regarding gang-related activities. They participated in "A Second's Chance," a true-to-life mock emergency department resuscitation and death of a gang member provided over an 18-month period. A questionnaire was completed by each participant. Forty-nine youths identified as at risk for gang involvement participated (37 male and 12 female, P Gang violence prevention should be channeled through maternal family members. History of incarcerated relatives, acquaintances, and neighborhood exposure to drugs and crime may represent additional risk factors for gang-related involvement. Demonstrations of gang violence scenarios raise awareness to consequences of gang-related activities. Family and neighborhood characteristics should be included in development of intervention scenarios.

    1994-01-01

    This study compared gang versus nongang high school students along measures of self-esteem, racial attitudes, and their self-professed role models. A total of 78 Caucasian (65 nongang and 13 gang members) and 77 African-American students (41 nongang and 36 gang members) participated. Results indicated that gang members had significantly lower levels of self-esteem compared to their nongang peers. All students, regardless of ethnicity, manifested negative racial stereotyping toward racial outgroups; gang members were not more racially prejudiced compared to other students. The role model data revealed that overall, gang members could name fewer role models than did their nongang peers. African-American students who were not gang members were much more likely to mention a parent or teacher as a role model. A regression analysis indicated that the absence of parental or teacher roles models was the best predictor of gang membership. These results are conceptualized within the framework provided by social identity theory.

    Research has established robust links between gang membership, delinquency, violence and victimization. Yet studies examining the process of gang desistance in general and that of core gang members in particular, are quite rare. The current study aims to identify factors associated with desistance of core gang members as well as describe the nature of the process that these "formers" have undergone. Thirty-nine core ex-gang members (80% males and 20% females) from the San Francisco Bay area and Los Angeles, with an average length of 11.6-years gang membership, were interviewed regarding their involvement in the gang and the desistance process. A systematic qualitative analysis based on grounded theory methodology was mainly utilized. We found that the decision to leave the gang is a result of a combination of push (e.g., personal and vicarious victimization, burnout of gang lifestyle, disillusionment by the gang) and pull (e.g., parenthood, family responsibilities, religious and cultural awakening) factors that evolved over time. Push factors were more dominant in this domain. We also found that while male core ex-gang members tended to leave the gang more frequently because of push factors, female ex-gang members were more inclined to desist due to pull factors. Our analysis also showed that core gang members shared a general pattern of the desistance process comprising of the following 5 stages: triggering, contemplation, exploration, exiting and maintenance. Based on these results, we outlined stage-specific recommendations for agents of societal change to help in facilitating the desistance of core gang members. (PsycINFO Database Record

    2014-01-01

    Over the past two decades, gang membership within the United States has continued to rise and has spread from urban centers to suburban and rural areas. Juvenile gang membership is of particular concern because of the relationship between early gang involvement and later adolescent and adult criminal behavior and incarceration. Female gang membership and affiliation are receiving increased attention as female crime and incarceration rates outpace those of their male counterparts. This study explores gender differences between male and female juveniles who have verified gang membership in one suburban jurisdiction. Findings suggest important differences between males and females, and implications for research and practice are discussed.

    2015-01-01

    Past applications of biosolids to soils at some locations added higher Cd levels than presently permitted. Cadmium phytoextraction would alleviate current land use constraints. Unamended farm soil, and biosolids amended farm and mine soils were obtained from a Fulton Co., IL biosolids management facility. Soils contained 0.16, 22.8, 45.3 mg Cd kg(-1) and 43.1, 482, 812 mg Zn kg(-1) respectively with initial pH 6.0, 6.1, 6.4. In greenhouse studies, Swiss chard (Beta vulgaris var. cicla), a Cd-accumulator maize (inbred B37 Zea mays) and a southern France Cd-hyperaccumulator genotype of Noccaea caerulescens were tested for Cd accumulation and phytoextraction. Soil pH was adjusted from ∼5.5-7.0. Additionally 100 rice (Oryza sativa) genotypes and the Ni-hyperaccumulator Alyssum murale were screened for potential phytoextraction use. Chard suffered phytotoxicity at low pH and accumulated up to 90 mg Cd kg(-1) on the biosolids amended mine soil. The maize inbred accumulated up to 45 mg Cd kg(-1) with only mild phytotoxicity symptoms during early growth at pH>6.0. N. caerulescens did not exhibit phytotoxicity symptoms at any pH, and accumulated up to 235 mg Cd kg(-1) in 3 months. Reharvested N. caerulescens accumulated up to 900 mg Cd kg(-1) after 10 months. Neither Alyssum nor 90% of rice genotypes survived acceptably. Both N. caerulescens and B37 maize show promise for Cd phytoextraction in IL and require field evaluation; both plants could be utilized for nearly continuous Cd removal. Other maize inbreds may offer higher Cd phytoextraction at lower pH, and mono-cross hybrids higher shoot biomass yields. Further, maize grown only for biomass Cd maximum removal could be double-cropped.

    Full Text Available This article is the result of an investigation on the cultural systems that sustain violence within gangs in marginalized neighborhoods of Cali, Colombia. It is about magical and religious beliefs of gang member that surround the episodes of violence, and that allow us to observe aspects of the psychology of the gang member that are functional adaptations to the reality of vendettas and territorial wars, which are intended to give sense and meaning to the tragic events of their lives. The study shows how Santeria was used to seek protection and harm the enemy, and how their ideas of God and the Devil, good and evil, lack of ethics that regulate the relationships with others, and are an expression of a narcissistic defense mechanism. It is concluded that this cultural belief system is an interesting transaction formula between objective social reality and subjective fantasies.

    2014-01-01

    Histidine is known to be involved in Ni hyperaccumulation. Recently, histidine-dependent xylem loading of Ni and Zn has been demonstrated in the Zn/Ni/Cd hyperaccumulator, Noccaea caerulescens. Here we tested the hypothesis whether Cd xylem loading is histidine-dependent, too. In contrast to that of Ni and Zn, the xylem loading of Cd was not affected by exogenous histidine. Histidine accumulation in root cells appears to facilitate the radial transport of Ni and Zn, but not Cd, across the roots. This may be due to the relatively high preference of Cd for coordination with sulfur over coordination with nitrogen, in comparison with Ni and Zn.

As expected, T. caerulescens generally showed better resistance to metal stress, which was reflected by higher Cd accumulation within plant tissues with no signs of chlorosis, or wilt. Glutathione reductase (GR) and superoxide dismutase (SOD) activities in fresh leaves were monitored as the plant metal-detoxifying response. In general, both plant species exhibited an increase trend of GR activity before declining at 100 microM likely due to excessive levels of phytotoxic Cd. SOD activity exhibited almost a similar variation pattern to GR and decreased also at 100 microM Cd. For both plant species, fluorescent PTS uptake (8-hydroxy-1,3,6-pyrenetrisulphonic acid) increased significantly with metal level in exposure solutions indicating that Cd has a comparable effect to drought or salinity in terms of the gain of relative importance in apoplastic bypass transport under such stress conditions.

    While violent crime has decreased in many cities in the USA, gang-related violence remains a serious problem in impoverished inner city neighborhoods. In Syracuse, New York, gang-related murders and gun shots have topped other New York state cities. Residents of the high-murder neighborhoods suffer trauma similar to those living in civil conflict zones. The Trauma Response Team was established in 2010, in collaboration with the Police Department, health care institutions, and emergency response teams and with the research support of Syracuse University faculty. Since its inception, gang-related homicides and gun shots have decreased in the most severely affected census tracts.

    Full Text Available OBJETIVO: Relatar o isolamento do vírus Ilheus no Estado de São Paulo e avaliar o seu impacto para a saúde pública. MÉTODOS: O isolamento de vírus foi realizado em camundongos albinos Swiss, a partir de sangue de aves silvestres, capturadas com redes de espera tipo mist net, armadas no nível do solo, no Parque Ecológico do Tietê, São Paulo. A identificação das cepas isoladas foi feita pelos testes de inibição da hemaglutinação, fixação de complemento e neutralização em camundongos. Amostras de plasma de aves e de mamíferos silvestres foram submetidas à pesquisa sorológica para detecção de anticorpos inibidores de hemaglutinação. RESULTADOS: Foram isoladas duas cepas do vírus Ilheus em sangue de aves das espécies Sporophila caerulescens e Molothrus bonariensis e detectados anticorpos em aves das espécies Columbina talpacoti, Geopelia cuneata, Molothrus bonariensis e Sicalis flaveola, em sagüis das espécies Callithrix jacchus e Callithrix penicillata e no quati Nasua nasua. CONCLUSÕES: O isolamento do vírus Ilheus e a detecção de anticorpos específicos em aves residentes, migratórias e de cativeiro, em sagüis e quatis, comprovam a presença desse agente no Parque Ecológico do Tietê. O comportamento migratório de aves silvestres pode determinar a introdução do vírus em outras regiões. Considerando-se a patogenicidade para o homem e a confirmação da circulação desse agente viral em área urbana, freqüentada para atividade de lazer e de educação, o risco de ocorrência de infecção na população humana não pode ser descartado.

    This study examines the risk and protective factors for gang involvement among subgroups of youth (i.e., current or former gang members, youth who resisted gang membership, and non-gang-involved youth) using the social-ecological framework. Middle and high school students (N = 17,366) from school districts in a large Midwestern county participated. Results indicated that males were more likely than females to be involved in gangs. For the individual context, our findings indicate that racial and ethnic minorities, females, and youth with depression/suicidal ideation are likely to be at risk for gang involvement. For the family context, we found that having gang-involved family members and family dysfunction are related to youth gang involvement. For the peer context, peers' alcohol and drug use and bullying were significantly associated with gang involvement. For the school context, as our results demonstrate, youth who perceived fair treatment from teachers and other adults in school and those with a sense of belonging in school are more likely to avoid gang membership. For the neighborhood context, we found that presence of adult support in the neighborhood and perceived neighborhood safety are negatively associated with gang membership. Findings suggest that gang prevention efforts need to target multiple ecologies that surround and influence youth. (PsycINFO Database Record

  9. Lithium isotope behaviour during weathering in the Ganges Alluvial Plain

    2017-02-01

    The Ganges river system is responsible for the transportation of a large flux of dissolved materials derived from Himalayan weathering to the oceans. Silicate weathering-driven cooling resulting from uplift of the Himalayas has been proposed to be a key player in Cenozoic climate variation. This study has analysed Li isotope (δ7Li) ratios from over 50 Ganges river waters and sediments, in order to trace silicate weathering processes. Sediments have δ7Li of ∼0‰, identical to bulk continental crust, however suspended sediment depth profiles do not display variations associated with grain size that have been observed in other large river systems. Dissolved δ7Li are low (∼11‰) in the Ganges headwaters, but reach a constant value of 21 ± 1.6‰ within a relatively short distance downstream, which is then maintained for almost 2000 km to the Ganges mouth. Given that Li isotopes are controlled by the ratio of primary mineral dissolution to secondary mineral formation, this suggests that the Ganges floodplain is at steady-state in terms of these processes for most of its length. Low δ7Li in the mountainous regions suggest silicate weathering is therefore at its most congruent where uplift and fresh silicate exposure rates are high. However, there is no correlation between δ7Li and the silicate weathering rate in these rivers, suggesting that Li isotopes cannot be used as a weathering-rate tracer, although they do inform on weathering congruency and intensity. The close-to-constant δ7Li values for the final 2000 km of Ganges flow also suggest that once the size of the alluvial plain reached more than ∼500 km (the flow distance after which riverine δ7Li stops varying), the Ganges exerted little influence on the changing Cenozoic seawater δ7Li, because riverine δ7Li attained a near steady-state composition.

    2005-10-01

    A prospective autopsy study in Rivers State, Nigeria, was undertaken to evaluate the patterns of death as a result of rival gang clashes and to highlight the menace of rival gang violence. Between 1 January 1999 and 31 December 2003 medico-legally autopsied bodies in Rivers State, where death was the result of gang violence, were studied after being served with the coroner's form. In all cases, standard autopsy procedures were adopted and reports were issued. A total of 58 bodies were autopsied for the study. Three (5.2%) were females and 55 (94.8%) were males, giving a female to male ratio of 1:18.3. The age group of 10-29 years recorded the highest frequency of death (65.6%) with a peak in the age group 20-29 years (39.7%). Gang violence and politically motivated mob action were the most common precipitating factors (60.3% and 20.7% respectively). Firearms (41.4%) was the most common method applied for the killing. Death was more common in the rural areas of Rivers State. Gang clashes, volatile political rallies, illegal drug peddling and illegal oil bunkering should be banned and stringent laws be passed. Such laws should also cover gun handling and should be enforced.

    2011-10-01

    We propose an agent-based model to simulate the creation of street gang rivalries. The movement dynamics of agents are coupled to an evolving network of gang rivalries, which is determined by previous interactions among agents in the system. Basic gang data, geographic information, and behavioral dynamics suggested by the criminology literature are integrated into the model. The major highways, rivers, and the locations of gangs’ centers of activity influence the agents’ motion. We use a policing division of the Los Angeles Police Department as a case study to test our model. We apply common metrics from graph theory to analyze our model, comparing networks produced by our simulations and an instance of a Geographical Threshold Graph to the existing network from the criminology literature.

    The response of youth gangs to "zero tolerance" policing in Honduras are examined with respect to territoriality. Focusing on two main gangs, the Mara Salvatrucha and the 18th Street Gang, the ways in which state authority is challenged are assessed from an analysis of body territoriality, the respatialisation of organisational structures across urban neighbourhoods, and the production of new enclosed spaces of gang territoriality. These redefinitions of group territoriality strengthen the emotional bonds and sense of belonging towards the gang, enabling the emergence of a transnational/imagined community.

    Given the robust positive association between gangs and crime, a better understanding of factors related to reported youth gang membership is critical and especially since youth in gangs are a universal concern. The present study investigated the role of delinquency, proactive aggression, psychopathy and behavioral school engagement in reported youth gang membership using a large sample of 1027 Singapore adolescents. Results from logistic regression showed that delinquency, proactive aggression, and behavioral school engagement were statistically significant risk factors for reported youth gang membership, and that psychopathy was not related to reported gang membership. Implications for prevention and intervention work with respect to youth gang membership were discussed. In particular, strengthening students' engagement with school and meaningful school-related activities and developing supportive teacher-student relationships are particularly important in working with young people with respect to prevention work. Additionally, the present study's theoretical and empirical contributions were also discussed.

  2. An integrated public health and criminal justice approach to gangs: What can research tell us?

    Directory of Open Access Journals (Sweden)

    Erika Gebo

    2016-12-01

    Full Text Available There has been a call to better link public health and criminal justice approaches to best address crime problems generally, and youth and gang violence in particular. Importantly, there has yet to be a systematic examination of how criminal justice approaches can be integrated within a public health framework. This paper examines the strengths and challenges with mapping gang research and evidence-informed practices onto a public health approach. Conceptual examination reveals benefits to utilizing an integrated framework, but it also exposes core problems with identification and prediction of gang joining and gang membership. The gang label as a master status is called into question. It is argued that a public health framework can inform public policy approaches as to when the focus should be youth violence versus gangs and gang violence.

    Many endemic fish species are threatened with extinction. Conservation strategies and the restoration of endemic fish after extinction must therefore be investigated. Although sperm cryopreservation is indispensable for the conservation of endangered fishes, the limited number of mature fish and limited availability (volume and period) of sperm from small endemic fish hinders the optimization and practical use of this material. In this report, we demonstrate the in vitro differentiation of fertile sperm from cryopreserved spermatogonia of juveniles of the endangered small cyprinid honmoroko (Gnathopogon caerulescens), which is endemic to Lake Biwa in Japan. The entire process of spermatogenesis was recapitulated in vitro using cryopreserved spermatogonia of non-spawning adult and juvenile fish. The differentiation of sperm from spermatogonia was captured as a time-lapse video and confirmed by 5-ethynyl-2‧-deoxyuridine (EdU) incorporation into sperm. Fertility was demonstrated by artificial insemination. These results suggest that the combination of cryopreservation of spermatogonia and in vitro sperm differentiation will provide a new and promising strategy for the preservation of paternal genetic materials.

    The phytoextraction of Zn may be improved by applying N fertilizers to increase the biomass and Zn content of shoots. Rhizosphere-pH change from uptake of different N forms will affect Zn phyto-availability in the rhizosphere and Zn phytoextraction. This glasshouse study examined the effect of N form on Zn phytoextraction by Thlaspi caerulescens (Prayon). The plants were grown in a Zn-contaminated soil (total Zn 250 mg kg-1 soil; pHwater 5.7) and supplied with (NH4)2SO4, Ca(NO3)2 or urea [(NH2)2CO]. The form was maintained by applying the nitrification inhibitor dicyandiamide. A biodegradable chelator ethylenediaminedisuccinic acid (EDDS) was included for comparison. The addition of N doubled the shoot biomass. The highest shoot Zn content occurred in the Ca(NO3)2 treatment and was associated with the highest rhizosphere pH. The lowest shoot dry weight occurred in the EDDS treatment. The Zn concentration in the shoots increased as the rhizosphere pH increased. A significant correlation occurred between Ca and Zn concentrations in the shoots. This study demonstrated that Ca(NO3)2 is a more effective treatment than , urea or EDDS for enhancing Zn phytoextraction in a mildly acidic soil.

    2016-04-01

    This study examined the associations of sexual risk behaviors, substance use, mental health, and trauma with varying levels of gang involvement in a sample of Los Angeles-based homeless youths. Data were collected from 505 homeless youths who self-reported various health information and whether they have ever identified as or been closely affiliated with a gang member. Multivariable logistic regression assessed associations of lifetime gang involvement with risk taking behaviors and negative health outcomes. Results revealed seventeen percent of youths have ever identified as a gang member and 46% as gang affiliated. Both gang members and affiliates were at greater risk of many negative behaviors than non-gang involved youths. Gang members and affiliates were more likely to report recent methamphetamine use, cocaine use, chronic marijuana use, having sex while intoxicated, and symptoms of depression, symptoms of posttraumatic stress disorder. They were also more likely to have experienced childhood sexual abuse and witnessing family violence. Gang members were more likely to ever attempt suicide, experience recent partner violence, and report physical abuse during childhood. Results suggest that lifetime gang involvement is related to a trajectory of negative outcomes and amplified risk for youths experiencing homelessness. Additionally, being closely connected to a gang member appears to have just as much as an impact on risk as personally identifying as a gang member. Given the lack of knowledge regarding the intersection between youth homelessness and gang involvement, future research is needed to inform policies and programs that can address the specific needs of this population.

    Zinc (Zn) is an essential trace element in all living organisms, but is toxic in excess. Several plant species are able to accumulate Zn at extraordinarily high concentrations in the leaf epidermis without showing any toxicity symptoms. However, the molecular mechanisms of this phenomenon are still poorly understood. A state-of-the-art quantitative 2D liquid chromatography/tandem mass spectrometry (2D-LC-MS/MS) proteomics approach was used to investigate the abundance of proteins involved in Zn hyperaccumulation in leaf epidermal and mesophyll tissues of Noccaea caerulescens. Furthermore, the Zn speciation in planta was analyzed by a size-exclusion chromatography/inductively coupled plasma mass spectrometer (SEC-ICP-MS) method, in order to identify the Zn-binding ligands and mechanisms responsible for Zn hyperaccumulation. Epidermal cells have an increased capability to cope with the oxidative stress that results from excess Zn, as indicated by a higher abundance of glutathione S-transferase proteins. A Zn importer of the ZIP family was more abundant in the epidermal tissue than in the mesophyll tissue, but the vacuolar Zn transporter MTP1 was equally distributed. Almost all of the Zn located in the mesophyll was stored as Zn-nicotianamine complexes. In contrast, a much lower proportion of the Zn was found as Zn-nicotianamine complexes in the epidermis. However, these cells have higher concentrations of malate and citrate, and these organic acids are probably responsible for complexation of most epidermal Zn. Here we provide evidence for a cell type-specific adaptation to excess Zn conditions and an increased ability to transport Zn into the epidermal vacuoles.

    Although gang-involved Latino youth in the United States are uniquely at risk of adverse consequences from sexual behavior, little research is available that can guide those who wish to develop interventions to reduce sexual risk among these youth. To facilitate the development of effective interventions, we identified cultural and contextual factors that influence sexual behavior and sex education among gang-involved Latino youth in one U.S. community. By analyzing transcripts from interviews and focus groups with three different groups of key stakeholders--gang-experienced Latino youth, the parents of gang-experienced Latino youth, and the personnel of a program providing comprehensive human services for gang-involved Latino youth--we identified three domains to be considered in developing sexual risk-reduction interventions for gang-involved U.S. Latino youth. The focus of our discussion is on the implications of these findings for future development or adaptation of interventions.

    The southeastern US sustains the highest high school dropout rates, and gangs persist in underserved communities. African American female adolescents who drop out of school and are gang members are at substantial risk of exposure to severe violence, physical abuse, and sexual exploitation. In this study of 237 female African American adolescents 16-19 years of age from North Carolina who dropped out or considered dropping out, 11% were current or past gang members. Adolescents who reported gang membership began smoking marijuana at a mean age of 13, whereas those who reported no gang membership began at a mean age of 15 years (Pgang members and non-gang members, respectively (P=0.04). Problem alcohol use was high in both groups: 40% and 65% for non-gang and gang members, respectively (P=0.02). Controlling for frequent marijuana use and problem alcohol use, adolescents who reported gang membership were more likely than non-gang members to experience sexual abuse (odds ratio [OR] =2.60, 95% confidence interval [CI] [1.06, 6.40]), experience physical abuse (OR =7.33, 95% CI [2.90, 18.5]), report emotional abuse from their main partner (OR =3.55, 95% CI [1.44, 8.72]), run away from home (OR =4.65, 95% CI [1.90, 11.4]), get arrested (OR =2.61, 95% CI [1.05, 6.47]), and report violence in their neighborhood including murder (OR =3.27, 95% CI [1.35, 7.96]) and fights with weapons (OR =3.06, 95% CI [1.15, 8.11]). Gang members were less likely to receive emotional support (OR =0.89, 95% CI [0.81, 0.97]). These findings reinforce the urgent need to reach young African American women in disadvantaged communities affiliated with gangs to address the complexity of context and interconnected risk behaviors.

  2. Mangrove wetland ecosystems in Ganges-Brahmaputra delta in Bangladesh

    2008-01-01

    The Sundarbans is one of the productive man-grove wetland ecosystems in the Ganges-Brahmaputra delta in Bangladesh. The delta is undergoing rapid eco-logical changes due to human activity. In the present study, surface water salinity data from 13 rivers of the Sundarbans were collected in order to investigate the sal-ine water intrusion in the mangrove wetlands. Results demonstrate that saline water has penetrated the upstream area as river water salinity has increased signifi-cantly in 1976 compared to the year 1968. The soil and river water salinity data also shows that it has crossed the water salinity threshold line in most parts of the Sundarbans wetlands. These observations are due to the construction of Farakka Barrage in 1975, which reduced the water discharge of the Ganges River from 3700 m3/s in 1962 to 364 m3/s in 2006. The shortage of freshwater dis-charge to the deltaic area is trailing active ecosystems function, especially in the dry season in the south western region in Bangladesh. The objective of this study is to understand and analyze the present degraded mangrove wetland ecosystems and their negative impacts. The find-ings of this study would contribute to the formulation of the mangrove wetland ecosystems management plan inthe Ganges delta of Bangladesh.

    2015-01-01

    Youth gang involvement is a serious public health challenge as adolescents involved in gangs are more likely than others to engage in violence and aggression. To better understand gang involvement, we examined the role of protective (empathy and parental support) and risk (peer deviance and lack of safety at school) factors, as well as their interactions, in predicting adolescent gang affiliation. The study involved a sample of 26,232 students (53.4% females; mean age = 14.62, SD = 1.69) participating in the California Healthy Kids Survey (CHKS), a survey investigating a wide range of youth health and risk behaviors administered in all California schools every 2 years. Using hierarchical linear modeling (HLM), findings indicated that high levels of empathy and parental support were associated with a lower likelihood of affiliating with a gang. Associating with deviant peers and perceiving the school as unsafe were positively correlated with gang membership. At the school level, lack of safety and type of school (special education, vocational, or alternative school vs. comprehensive schools) were associated with greater probability of gang membership. Empathy mitigated the association between deviant peers and gang membership.

  18. Ganges Valley Aerosol Experiment: Science and Operations Plan

    Energy Technology Data Exchange (ETDEWEB)

    Kotamarthi, VR

    2010-06-21

    The Ganges Valley region is one of the largest and most rapidly developing sections of the Indian subcontinent. The Ganges River, which provides the region with water needed for sustaining life, is fed primarily by snow and rainfall associated with Indian summer monsoons. Impacts of changes in precipitation patterns, temperature, and the flow of the snow-fed rivers can be immense. Recent satellite-based measurements have indicated that the upper Ganges Valley has some of the highest persistently observed aerosol optical depth values. The aerosol layer covers a vast region, extending across the Indo-Gangetic Plain to the Bay of Bengal during the winter and early spring of each year. The persistent winter fog in the region is already a cause of much concern, and several studies have been proposed to understand the economic, scientific, and societal dimensions of this problem. During the INDian Ocean EXperiment (INDOEX) field studies, aerosols from this region were shown to affect cloud formation and monsoon activity over the Indian Ocean. This is one of the few regions showing a trend toward increasing surface dimming and enhanced mid-tropospheric warming. Increasing air pollution over this region could modify the radiative balance through direct, indirect, and semi-indirect effects associated with aerosols. The consequences of aerosols and associated pollution for surface insolation over the Ganges Valley and monsoons, in particular, are not well understood. The proposed field study is designed for use of (1) the ARM Mobile Facility (AMF) to measure relevant radiative, cloud, convection, and aerosol optical characteristics over mainland India during an extended period of 9–12 months and (2) the G-1 aircraft and surface sites to measure relevant aerosol chemical, physical, and optical characteristics in the Ganges Valley during a period of 6–12 weeks. The aerosols in this region have complex sources, including burning of coal, biomass, and biofuels; automobile

  1. Reviving the "Ganges Water Machine": where and how much?

    Directory of Open Access Journals (Sweden)

    L. Muthuwatta

    2015-09-01

    Full Text Available Surface runoff generated in the monsoon months in the upstream parts of the Ganges River Basin contributes substantially to downstream floods, while water shortages in the dry months affect agricultural production in the basin. This paper examines the parts (sub-basins of the Ganges that have the potential for augmenting subsurface storage (SSS, increase the availability of water for agriculture and other uses, and mitigate the floods in the downstream areas. The Soil and Water Assessment Tool (SWAT is used to estimate sub-basin-wise water availability. The water availability estimated is then compared with the sub-basin-wise un-met water demand for agriculture. Hydrological analyses revealed that five sub-basins produced more than 10 billion cubic meters (B m3 of annual surface runoff consistently during the simulation period. In these sub-basins, less than 50 % of the annual surface runoff is sufficient to irrigate all irrigable land in both the \\textit{Rabi} (November to March and summer (April to May seasons. Further, for most of the sub-basins, there is sufficient water to meet the un-met water demand, provided that it is possible to capture the surface runoff during the wet season. It is estimated that the average flow to Bihar State from the upstream of the Ganges, a downstream basin location, is 277 ± 121 B m3, which is more than double the rainfall in the state alone. Strong relationships between outflows from the upstream sub-basins and the inflows to Bihar State suggested that flood inundation in the state could be reduced by capturing a portion of the upstream flows during the peak runoff periods.

    2012-02-01

    Gang violence is a growing public health concern in the United States, and adolescents are influenced by exposure to gang violence. This study explored the influence of exposure to gang violence on adolescent boys' mental health using a multi-method design. A semi-structured interview guide and the Trauma Symptom Checklist for Children were used to collect data from adolescents. Parents, primary caregivers, and community center employees completed the Child Behavior Checklist or Teacher Report Form. Ten adolescent boys, their parents or primary caregivers, and six community center employees participated in the study. Exposure to gang violence was common among these adolescents and they had a variety of reactions. Parents, primary caregivers, and community center employees had differing perceptions of adolescents' exposure to violence and their mental health. Adolescent boys' exposure to gang violence in the community is alarming. These adolescents encountered situations with violence that influenced their mental health.

    Gordon, Rachel A; Rowe, Hillary L; Pardini, Dustin; Loeber, Rolf; White, Helene Raskin; Farrington, David P

    2014-06-01

    Using Pittsburgh Youth Study data, we examined the extent to which over 600 gang members and non-gang involved young men specialized in drug selling, serious theft, or serious violence or engaged simultaneously in these serious delinquent behaviors, throughout the 1990s. We found that the increase in delinquency associated with gang membership was concentrated in two combinations: serious violence and drug selling; serious violence, drug selling, and serious theft. Several covariates were similarly associated with multi-type serious delinquency and gang membership (age, historical time, Black race, and residential mobility), suggesting that these behaviors may share common developmental, familial, and contextual risks. We encourage future research to further examine the association of gang membership with engagement in particular configurations of serious delinquency.

    2015-01-01

    Full Text Available Using cross-sectional data collected from three middle schools in Southeast Los Angeles, we assessed the association of neighborhood violence exposure, gang associations, and social self-control with past week aggression in a sample of minority youth (n=164. Results from Poisson and logistic regression models showed that direct exposure to gun violence, having friends in gangs, and low social self control were all positively associated with past week aggression. Among girls, having gang affiliated family members was positively associated with aggression, whereas among boys having friends in gangs was associated with past week aggression. Subjective expectations of engagement in future interpersonal violence were associated with being male, having friends in gangs, and fear of neighborhood gun violence. We recommend that youth violence prevention and intervention programs address the impact of family, peers, and gun violence on student coping and identify students with low social self-control who could benefit from social and emotional skills training.

    2016-01-01

    Artemisia caerulescens subsp. densiflora Viv. is a rare endemic species from Corsica and Sardinia. We studied a sample collected from Razzoli, an island of the La Maddalena Archipelago. The polar secondary metabolites content of this species was investigated for the first time in this study showing the presence of sesquiterpenoids, flavonoids, caffeoylquinic acids and a coumarin, with the presence of several compounds already recognised in this genus. The metabolites composition was analysed in two different phenological stages, post blooming and flowering. During the blooming stage, the plant showed a molecular pattern mainly represented by sesquiterpenes and sterols with a minor amount of phenolics, while in flowering stage the molecular pattern was more rich in flavonoids and phenylpropanoids.

  7. Beyond Gang Truces and Mano Dura Policies: Towards Substitutive Security Governance in Latin America

    Directory of Open Access Journals (Sweden)

    Moritz Schuberth

    2016-12-01

    Full Text Available With responses to urban violence receiving increasing academic attention, the literature on anti-gang efforts in Latin America has focused mainly on coercive 'mano dura' policies and cooperative gang truces. Yet, there remains a paucity of studies going beyond such carrots-and-sticks approaches towards gangs. To fill this gap, this study investigates the possibilities and limitations of substitutive security governance across Latin America and the Caribbean. More specifically, this article looks at Disarmament, Demobilisation and Reintegration (DDR programmes in Medellín, Armed Violence Reduction and Prevention (AVRP efforts in Haiti and Security Sector Reform (SSR in Guatemala and Rio de Janeiro. It will be argued that communities are driven to support gangs against the oppressive state when they are indiscriminately targeted through muscular operations. Likewise, engaging gangs in dialogue grants them legitimacy and further weakens the position of the state. Therefore, the only sustainable solution lies in substitutive security governance, which aims to replace the functions gangs fulfil for their members, sponsors, and the community in which they are nested with a modern and accountable state that is bound by the rule of law. Still, substitutive strategies vis-à-vis gangs have their own limitations, which can only be overcome by way of an integrated and coordinated framework.

    2013-08-01

    Empirical evidence examining how risk and protective behaviors may possibly mediate the association between gang membership and school violence is limited. This study utilizes a statewide representative sample of 152 023 Latino, Black and White seventh graders from California to examine a theoretical model of how school risk (e.g. truancy, school substance use and risky peer approval) and protective (e.g. connectedness, support and safety) behaviors and attitudes mediate the effects of gang membership on school violence behaviors. The dataset was collected in the 2005-2006 and 2006-2007 academic school years using the ongoing large-scale California Healthy Kids Survey conducted by WestEd for the State of California. Approximately 9.5% of the sample considered themselves to be a member of a gang. The findings indicate that school risk behaviors and attitudes mediate the association between gang membership and school violence behaviors. Although the direct negative association between gang membership and school violence perpetration is weak, the positive indirect effect mediated by school risks behaviors and attitudes is strong. This indicates that when gang members engage in school risk behaviors, they are much more likely to be school violence perpetrators. Implications for further research, theory and practice for both gang and school violence researchers are discussed.

  9. Rumination and the displacement of aggression in United Kingdom gang-affiliated youth.

    Science.gov (United States)

    Vasquez, Eduardo A; Osman, Sarah; Wood, Jane L

    2012-01-01

    The concept of gang aggression oftentimes elicits images of brutal intergang violence. In reality, gang-related aggression can vary widely, can have various motivations and causal factors, and includes interpersonal as well as intergroup aggression. This study examined the tendency of UK youth to engage in displaced aggression (aggression aimed at undeserving targets) and examined the relationship among gang affiliation, ruminative thought, and aggression levels. Students in three London schools were asked to complete a questionnaire that assessed levels of gang affiliation, rumination about aversive events, and a tendency to engage in displaced aggression. Our analyses found a three-way interaction between gang affiliation, rumination, and gender, such that males who were high in affiliation and rumination had the greatest tendency to displace aggression toward innocent others. Additionally, it was shown that rumination could account for a significant part of the correlation between gang affiliation and displaced aggression. Furthermore, regression analyses showed that even after controlling for trait aggression, anger, hostility, and irritability, rumination remained a significant predictor of displaced aggression. The implications for understanding gang-related aggression and for conducting future research in this area were discussed.

    Full Text Available The present study was conducted along the upper Ganges River between Narora barrages and Anupshahar from January to June 2007. Community interviews were conducted in order to assess the socio-economic profile of the fishermen community, their level of dependence on the river and their attitude towards the conservation of Ganges River Dolphin Platanista gangetica gangetica.

The respondents were found to be well aware of the river biodiversity and believed excessive water extraction and pollution to be the responsible for any perceived decline in the dolphin population. About 55% of the fishermen were found to fish for commercial purposes, and a majority of them (71% used nylon gill-nets. A majority (94% of respondents that had boats of their own fished in the middle of the river, an activity often conducted in groups. 12% of respondents reported to have encountered dolphin carcasses. Excessive fishing and dolphin poaching were found to be interrelated; if fishing can be more effectively managed poaching may automatically decline. 41% of the fishermen interviewed were found to be willing to stop fishing providing adequate alternative livelihoods are provided by the government.

    Epidemiological methods and public health theories can be tied to theories of crime and delinquency and used to create evidence-based policy. Interdisciplinary theoretical approaches to existing, and emerging, public health and criminal justice problems hold great promise. Differential association theory postulates that close association with delinquent peers leads to an increase in deviant activities such as illicit drug use. Social cognitive theory postulates that health behavior change is driven by the interaction of (a) cognitive states that support a health outcome, (b) the social and contextual environment, (c) and individual action. Combined, these theories can be applied to drug eradication programs as well as other health and crime issues. Focus groups and interviews were performed to identify rates of illicit substance use among incarcerated African American adolescent male gang members and nongang members. The policy recommendations illustrate the convergence of criminological and epidemiological theory under the new paradigm of epidemiological criminology or ''EpiCrim.''

  13. Ganges Valley Aerosol Experiment (GVAX) Final Campaign Report

    In general, the Indian Summer Monsoon (ISM) as well as the and the tropical monsoon climate is influenced by a wide range of factors. Under various climate change scenarios, temperatures over land and into the mid troposphere are expected to increase, intensifying the summer pressure gradient differential between land and ocean and thus strengthening the ISM. However, increasing aerosol concentration, air pollution, and deforestation result in changes to surface albedo and insolation, potentially leading to low monsoon rainfall. Clear evidence points to increasing aerosol concentrations over the Indian subcontinent with time, and several hypotheses regarding the effect on monsoons have been offered. The Ganges Valley Aerosol Experiment (GVAX) field study aimed to provide critical data to address these hypotheses and contribute to developing better parameterizations for tropical clouds, convection, and aerosol-cloud interactions. The primary science questions for the mission were as follows:

    Kelly, Sarah E; Anderson, Debra G

    2012-10-01

    Adolescents are exposed to various forms of gang violence, and such exposure has led them to feel unsafe in their neighborhood and have differing interactions with their parents and peers. This qualitative study explored adolescents', parents', and community center employees' perceptions of adolescents' interaction with their neighborhood, family, and peers. Three themes emerged from the data: Most adolescents reported that the community center provided a safe environment for them; parental engagement influenced adolescents' experiences with gangs; and adolescents were subjected to peer pressure in order to belong. Exposure to gang violence can leave an impression on adolescents and affect their mental health, but neighborhood safety and relationships with parents and peers can influence adolescents' exposure to gang violence. Recommendations regarding the use of health care professionals at community centers are proposed.

    Full Text Available This article considers what demobilisation, disarmament, and reintegration (DDR programmes might learn from research on gangs and the problems associated with government-instituted ‘wars on gangs’ putatively aimed at reducing or fighting gang-related violence. It begins by considering interventions associated with the global war on gangs, and compares their underlying premises and practices with those of DDR programmes while highlighting how both are plagued with problems associated with drawing on de-contextualized templates. Drawing on long-term ethnographic research carried out in Nicaragua and South Africa, the article then goes on to explore why individuals leave gangs, focusing in particular on the more organic processes that deplete gangs of their members, as well as the consequences that the different possible occupational trajectories of ex-gang members can have for patterns of violence. These offer a number of potential lessons for DDR programmes, particularly with regard to reducing violence in a realistic and sustainable manner.

African American female adolescents who drop out of school and are gang members are at substantial risk of exposure to severe violence, physical abuse, and sexual exploitation. In this study of 237 female African American adolescents 16–19 years of age from North Carolina who dropped out or considered dropping out, 11% were current or past gang members. Adolescents who reported gang membership began smoking marijuana at a mean age of 13, whereas those who reported no gang membership began at a mean age of 15 years (P<0.001. The mean ages of first alcohol use were 14 years and 15 years for gang members and non-gang members, respectively (P=0.04.

  1. Murder by structure: dominance relations and the social structure of gang homicide.

    Science.gov (United States)

    Papachristos, Andrew V

    2009-07-01

    Most sociological theories consider murder an outcome of the differential distribution of individual, neighborhood, or social characteristics. And while such studies explain variation in aggregate homicide rates, they do not explain the social order of murder, that is, who kills whom, when, where, and for what reason. This article argues that gang murder is best understood not by searching for its individual determinants but by examining the social networks of action and reaction that create it. In short, the social structure of gang murder is defined by the manner in which social networks are constructed and by people's placement in them. The author uses a network approach and incident-level homicide records to recreate and analyze the structure of gang murders in Chicago. Findings demonstrate that individual murders between gangs create an institutionalized network of group conflict, net of any individual's participation or motive. Within this network, murders spread through an epidemic-like process of social contagion as gangs evaluate the highly visible actions of others in their local networks and negotiate dominance considerations that arise during violent incidents.

    We examined drug-scene familiarity and exposure to gang violence among residents of a migrant farming community in rural Baja California, Mexico. In October 2010, 164 members of a single colonia (community) underwent an interviewer-administered survey to assess ‘exposure to gang violence’ and ‘drug-scene familiarity’, as well as other health indicators. Logistic regression was used to identify correlates of exposure to gang violence. Overall, 20% of participants were male, the median age was 27 years, 24% spoke an indigenous language, 42% reported exposure to gang violence, and 39% reported drug-scene familiarity. Factors independently associated with exposure to gang violence included being younger (AOR=0.80 per 5-year increase, 95% CI=0.67–0.96), living in the community longer (AOR=1.47 per 5-year increase, 95% CI=1.11–1.72), higher educational attainment (AOR=1.70 per 5-year increase, 95% CI=1.07–1.12), and drug-scene familiarity (AOR=5.10, 95%CI=2.39–10.89). Exposure to gang violence was very common in this community and was associated with drug-scene familiarity, suggesting a close relationship between drugs and gang violence in this rural community. In a region characterised by mass migration from poorer parts of Mexico, where drugs and gangs have not been previously reported, emerging social harms may affect these communities unless interventions are implemented.

    2015-05-01

    In non-gang populations, the degree of identification with an in-group and perceptions of out-group entitativity, the perception of an out-group as bonded or unified, are important contributors to group-based aggression or vicarious retribution. The link between these factors and group-based aggression, however, has not been examined in the context of street gangs. The current study assessed the relationship among in-group identification, perceptions of out-group entitativity, and the willingness to retaliate against members of rival groups who did not themselves attack the in-group among juvenile gang and non-gang members in London. Our results showed the predicted membership (gang/non-gang) × in-group identification × entitativity interaction. Decomposition of the three-way interaction by membership revealed a significant identification × entitativity interaction for gang, but not for non-gang members. More specifically, gang members who identify more strongly with their gang and perceived a rival group as high on entitativity were more willing to retaliate against any of them. In addition, entitativity was a significant predictor of group-based aggression after controlling for gender, in-group identification, and gang membership. Our results are consistent with socio-psychological theories of group-based aggression and support the proposal that such theories are applicable for understanding gang-related violence. Aggr.

    A modified predator-prey model with transmissible disease in both the predator and prey species is proposed and analysed, with infected prey being more vulnerable to predation and infected predators hunting at a reduced rate. Here, the predators are the police and the prey the gang members. In this system, we examine whether police control of gangs is possible. The system is analysed with the help of stability analyses and numerical simulations. The system has five steady states-four of which involve no core gang members and one in which all the populations coexist. Thresholds are identified which determine when the predator and prey populations survive and when the disease remains endemic. For parameter values where the spread of disease among the police officers is greater than the death of the police officers, the diseased predator population survives, when it would otherwise become extinct.

    2014-10-01

    To examine associations between parental military service and school-based weapon carrying, school-based physical fighting and gang membership among youth. We used cross-sectional data from the 2008 Washington State Healthy Youth Survey collected in 8th, 10th, and 12th grades of public schools (n = 9,987). Parental military service was categorized as none (reference group), without combat zone deployment, or deployed to a combat zone. Multivariable logistic regression was used to test associations between parental military service and three outcomes: school-based weapon carrying, school-based physical fighting and gang membership. Standard errors were adjusted for the complex survey design. In 8th grade, parental deployment was associated with higher odds of reporting gang membership (OR = 1.8) among girls, and higher odds of physical fighting (OR = 1.6), and gang membership (OR = 1.9) among boys. In 10th/12th grade, parental deployment was associated with higher odds of reporting physical fighting (OR = 2.0) and gang membership (OR = 2.2) among girls, and physical fighting (OR = 2.0), carrying a weapon (OR = 2.3) among boys. Parental military deployment is associated with increased odds of reporting engagement in school-based physical fighting, school-based weapon carrying, and gang membership, particularly among older youth. Military, school, and public health professionals have a unique, collaborative opportunity to develop school- and community-based interventions to prevent violence-related behaviors among youth and, ultimately, improve the health and safety of youth in military families. Ideally, such programs would target families and youth before they enter eighth grade.

    Substantial natural contamination from trace elements (like arsenic) and pathogens make Ganges Deltaic aquifers an area of utmost concern. Following millions of cases of chronic arsenic poisoning from the groundwaters of the region, numerous residents are still knowingly ingesting water from shallow to intermediate accessible depth drinking water wells. Added to the calamity of arsenic is the prevalence of pathogenic bacteria in these waters. The increasing frequency of gastroenteritis signifies the need to quantify the magnitude and extensiveness of health degrading agents--bacterial pathogens (i.e. Salmonella) and non-pathogens (i.e. Enterobacteriaceae) --within the water supply in accessible Gangetic aquifers. To assess the dissolved microbiological quality in the region, present study sampling locations are along defined piezometer nests in an area in SE Asia (Bangladesh). Every nest contains samples from wells at varying depths covering shallow to deep aquifers. To date, 17 of the 76 water samples were analyzed for Salmonella, generic Escherichia coli (E. coli) and coliforms. Briefly, samples were plated in duplicate onto E. coli/Coliform petrifilm and incubated at 370C for 48 hours. Next, each sample was enriched in buffered peptone water and incubated at 370C for 18 hours. Bacterial DNA was extracted and amplified using a qPCR machine. Amplification plots were analyzed to determine presence/absence of microorganisms. All water samples (n=~76) are analyzed for Salmonella, Escherichia coli O157:H7, Listeria spp. and Shigella. Pathogen populations of PCR-positive water samples are enumerated using the agar direct plate method. Non-pathogenic bacterial indicator organisms (i.e. Enterobacteriaceae) will also be enumerated. Over the course of the experiment, we hypothesize that shallower wells will 1)have a higher pathogen prevalence and 2)harbor pathogens and nonpathogens at higher concentrations. While the 17 samples analyzed to date were negative for Salmonella

    1995-03-01

    An analysis was undertaken of the number of gunshot wound victims seen at a Los Angeles County hospital both before and after the Los Angeles riot. Since the LA riot the gang truce between the "Bloods" and the "Crips" resulted in a significant decrease in the number of gunshot wound victims seen at a level I trauma center in Los Angeles. Unfortunately, this lasted for only three months. The resurgence of shootings, mainly of the drive-by type (82%), to an occurrence rate higher than ever before, has negated any positive effect of the gang truce and indicates the need for additional measures to control gang violence.

    Full Text Available In 2002, the presence of gangs was detected in Catalonia. The groups had their origins in bands from the American continent, with whom they maintained communication and dependency relationships. Since then, there has been steady increase both in the number of gangs and youth involved in them, as well as the level of criminal activity linked to these groups. The police corps have followed the evolution of these groups closely, although the social context is radically different and the levels of crime and violence are not comparable to the other side of the Atlantic. This article seeks to explain the Catalonia Government Troopers’ approach to this phenomenon during this time.DOI: http://dx.doi.org/10.5377/rpsp.v1i2.1360

    Full Text Available The Latino gangs that have come into existence in Spain represent a potential risk factor for citizens’ security and coexistence. That is the view of security forces and organisations, and it also seems to be the understanding reached by the administrations of the Autonomous Communities of Catalonia and Madrid, whose actions in the light of this phenomenon are assessed in this work. To this end, the author begins with an analysis of the significance of Latino gangs inSpain, from their origins to their introduction, and carries out a review of their current situation, including their organisation, recruitment, impact and risk for citizen security. Only with suchan analysis can one begin to comprehend the scenario of dangers that will appear in the future, and the police strategy that should be introduced to deal with the phenomenon.

  19. Geomorphology of the Ganges fluvial system in the Himalayan foreland: an update

    Directory of Open Access Journals (Sweden)

    2004-12-01

    Full Text Available The Ganges is one of the largest fluvial systems in the world rising from the loftiest Himalaya and draining into the Bay of Bengal. Together with the Brahmaputra, it also constitutes the largest delta in the world before finally meeting the sea. The Ganges system passes through a variety of terrain from the rugged mountains through the flat alluvial plains and the sea margin, and also transects variable climatic zones. As a result, the processes, landforms and stratigraphy are strikingly different in different zones of the system. This paper attempts to provide an update on our understanding of this very large and diverse system. A global effort has been made in the last few decades, and the research has focused on a variety of themes. The mountainous catchments have attracted attention in view of the extent of glaciation and extensive erosional processes. The alluvial plains of the Ganges symbolizes the life line of one of the world's largest population. Consequently, a number of studies have been carried out on the morphology, hydrology including flooding history and sediment transport behaviour of the river system. The alluvial stratigraphy of the large valleys and the interfluves in the plains has provided insight about the sedimentation pattern and response to climate change. The deltaic plain is the final destination of this huge sediment dispersal system before it drains into the sea, and it also records the influence of sea level changes apart from the upstream catchment controls over a period of time.

    A pronounced spatial variability characterizes the subsidence/uplift rates in the Ganges-Bangladesh delta estimated from both sediment cores and modern geodetic techniques. The large variability of the subsidence rates suggests an interplay of different natural and anthropogenic processes including tectonics, sediment loading and sediment compaction, groundwater extaction among many others drivers of the delta vertical land movements.In this study, we focus on estimating the subsidence rates due to the sediments transported by the Ganges-Brahmaputra since the last 18 000 years. The delta subsidence induced by the sediment loading and the resulting sea level changes are modelled by the TABOO and SELEN software (Spada, 2003; Stocchi and Spada, 2007) in the framework of a gravitationally self-consistent Earth model. The loading history was obtained from available sediment cores and from the isopach map of Goodbread and Kuehl (2000). The results demonstrate that the delta loading enhanced by the Holocene sedimention can be responsable for a regular subsidence across the Ganges-Brahmaputra delta with an amplitude of 1-5 mm/yr along the Bengal coast. These estimates demonstrate that the contribution of the Holocene as well as modern sediment loading should be taken into account in climate change mitigation politicy for Bangladesh.

    Bangladesh is crisscrossed by the branches and tributaries of three main river systems, the Ganges, Bramaputra and Meghna (GBM). The temporal variation of water availability of those rivers has an impact on the different water usages such as irrigation, urban water supply, hydropower generation, navigation etc. Thus, seasonal flow outlook can play important role in various aspects of water management. The Flood Forecasting and Warning Center (FFWC) in Bangladesh provides short term and medium term flood forecast, and there is a wide demand from end-users about seasonal flow outlook for agricultural purposes. The objective of this study is to develop a seasonal flow outlook model in Bangladesh based on rainfall forecast. It uses European Centre for Medium-Range Weather Forecasts (ECMWF) seasonal precipitation, temperature forecast to simulate HYDROMAD hydrological model. Present study is limited for Ganges and Brahmaputra River Basins. ARIMA correction is applied to correct the model error. The performance of the model is evaluated using coefficient of determination (R2) and Nash-Sutcliffe Efficiency (NSE). The model result shows good performance with R2 value of 0.78 and NSE of 0.61 for the Brahmaputra River Basin, and R2 value of 0.72 and NSE of 0.59 for the Ganges River Basin for the period of May to July 2015. The result of the study indicates strong potential to make seasonal outlook to be operationalized.

    Research with substance-abusing samples suggests that eliciting commitment language during treatment may improve motivation to change, increase treatment engagement, and promote positive treatment outcomes. However, the relationship between in-session client language and treatment success is not well-understood for youth offender populations. This study evaluated the relationship between commitment language, treatment engagement (i.e., homework completion), and weekly employment outcomes for six gang-affiliated juvenile offenders participating in an employment counseling intervention. Weekly counseling sessions were audio-recorded, transcribed, and coded for commitment language strength. Multilevel models were fit to the data to examine the relationship between commitment language and counseling homework or employment outcomes within participants over time. Commitment language strength predicted subsequent homework completion but not weekly employment. These findings imply that gang-affiliated delinquent youth who express motivation to change during employment counseling will be more likely to comply with counselor-initiated homework. Further research on counselor techniques for promoting commitment language among juvenile gang offenders is needed.

    Full Text Available Since they surfaced during the final phase of the Internal Conflict in El Salvador, gangs have always used the firearms that were available on the formal and illegal markets. Once the war concluded, and despite new regulations regarding possession of firearms, gang members were able to access them through two means: purchasing on the commercial market, and creating them themselves.This initial acquisition of firearms evolved to acquisition of heavier firepower; particularly assault rifles, and guns that are able to shoot shotgun shells, as well as traditional gauges (9x19 mm, .45, and .38. The cause of this could be directly linked to two factors. On the one hand, the war between two main gangs, the “MS” and the “Barrio 18” –as could be expected– increased the need for greater firepower. On the other hand, there was greater availability of firearms on the market, such as assault rifles, and machine guns, as a result of the war.DOI: http://dx.doi.org/10.5377/rpsp.v4i1.1558

    In marginalized urban neighborhoods across the USA, Latino youth are disproportionately represented among the growing number of youth gangs. Substance use among gang-involved youth poses both immediate and long-term health risks and can threaten educational engagement, future socioeconomic stability, and desistance. Conventional assessments of gang-affiliated youth and their peer network overlook the possibility that positive peer ties may exist and can foster health promoting behavior norms. Drawing on a positive deviance framework, in this study, we examine the relationship between positive peer network characteristics tied to post-secondary educational aspirations and frequent alcohol and marijuana use among Latino, gang-affiliated youth from a neighborhood in San Francisco. Using generalized estimating equations regression models across 72 peer network clusters (162 youth), we found that having close friends who plan to go to a 4-year college was associated with a lower odds of frequent marijuana and alcohol use (OR 0.27, p = 0.02; OR 0.29, p = 0.14, respectively) and that this association persisted when adjusting for risk characteristics (OR 0.19, p gang intervention efforts by identifying protective and risk factors associated with non-criminal health outcomes to inform participatory research approaches and asset-based interventions that contribute to building healthy communities.

    Ecosystems provide the basis for human civilization and natural capital for green economy and sustainable development. Ecosystem services may range from crops, fish, freshwater to those that are harder to see such as erosion regulation, carbon sequestration, and pest control. Land use changes have been identified as the main sources of coastal and marine pollution in Bangladesh. This paper explores the temporal variation of agricultural land use change and its implications with ecosystem services in the Ganges delta. With time agricultural lands have been decreased and wetlands have been increased at a very high rate mainly due to the growing popularity of saltwater shrimp farming. In a span of 28 years, the agricultural lands have been reduced by approximately 50%, while the wetlands have been increased by over 500%. A large portion (nearly 40%) of the study area is covered by the Sundarbans which remained almost constant which can be attributed to the strict regulatory intervention to preserve the Sundarbans. The settlement & others land use type has also been increased to nearly 5%. There is a gradual uptrend of shrimp and fish production in the study area. The findings suggest that there are significant linkages between agricultural land use change and ecosystem services in the Ganges delta in Bangladesh. The continuous decline of agricultural land (due to salinization) and an increase of wetland have been attributed to the conversion of agricultural land into shrimp farming in the study area. Such land use change requires significant capital, therefore, only investors and wealthier land owners can get the higher profit from the land conversion while the poor people is left with the environmental consequences that affect their long-term lives and livelihood. An environmental management plan is proposed for sustainable land use in the Ganges delta in Bangladesh.

  11. Differential heating in the Indian Ocean differentially modulates precipitation in the Ganges and Brahmaputra basins

    Pervez, Md Shahriar; Henebry, Geoffrey M.

    2016-01-01

    Indo-Pacific sea surface temperature dynamics play a prominent role in Asian summer monsoon variability. Two interactive climate modes of the Indo-Pacific—the El Niño/Southern Oscillation (ENSO) and the Indian Ocean dipole mode—modulate the amount of precipitation over India, in addition to precipitation over Africa, Indonesia, and Australia. However, this modulation is not spatially uniform. The precipitation in southern India is strongly forced by the Indian Ocean dipole mode and ENSO. In contrast, across northern India, encompassing the Ganges and Brahmaputra basins, the climate mode influence on precipitation is much less. Understanding the forcing of precipitation in these river basins is vital for food security and ecosystem services for over half a billion people. Using 28 years of remote sensing observations, we demonstrate that (i) the tropical west-east differential heating in the Indian Ocean influences the Ganges precipitation and (ii) the north-south differential heating in the Indian Ocean influences the Brahmaputra precipitation. The El Niño phase induces warming in the warm pool of the Indian Ocean and exerts more influence on Ganges precipitation than Brahmaputra precipitation. The analyses indicate that both the magnitude and position of the sea surface temperature anomalies in the Indian Ocean are important drivers for precipitation dynamics that can be effectively summarized using two new indices, one tuned for each basin. These new indices have the potential to aid forecasting of drought and flooding, to contextualize land cover and land use change, and to assess the regional impacts of climate change.

    The objective of this study is to compare the effectiveness of three algorithms that estimate discharge from remotely sensed observables (river width, water surface height, and water surface slope) in anticipation of the forthcoming NASA/CNES Surface Water and Ocean Topography (SWOT) mission. SWOT promises to provide these measurements simultaneously, and the river discharge algorithms included here are designed to work with these data. Two algorithms were built around Manning's equation, the Metropolis Manning (MetroMan) method, and the Mean Flow and Geomorphology (MFG) method, and one approach uses hydraulic geometry to estimate discharge, the at-many-stations hydraulic geometry (AMHG) method. A well-calibrated and ground-truthed hydrodynamic model of the Ganges river system (HEC-RAS) was used as reference for three rivers from the Ganges River Delta: the main stem of Ganges, the Arial-Khan, and the Mohananda Rivers. The high seasonal variability of these rivers due to the Monsoon presented a unique opportunity to thoroughly assess the discharge algorithms in light of typical monsoon regime rivers. It was found that the MFG method provides the most accurate discharge estimations in most cases, with an average relative root-mean-squared error (RRMSE) across all three reaches of 35.5%. It is followed closely by the Metropolis Manning algorithm, with an average RRMSE of 51.5%. However, the MFG method's reliance on knowledge of prior river discharge limits its application on ungauged rivers. In terms of input data requirement at ungauged regions with no prior records, the Metropolis Manning algorithm provides a more practical alternative over a region that is lacking in historical observations as the algorithm requires less ancillary data. The AMHG algorithm, while requiring the least prior river data, provided the least accurate discharge measurements with an average wet and dry season RRMSE of 79.8% and 119.1%, respectively, across all rivers studied.

    Full Text Available By the end of 2011, the US Customs and Border Protection (CBP began to see a steady rise in the number of Unaccompanied Alien Children (UAC from Central America, particularly from the Northern Triangle countries—El Salvador, Honduras and Guatemala—arriving to the US-Mexico border. The number of children entering the United States from these countries more than doubled during fiscal year (FY 2012 and continued to grow through FY 2014. In FY 2013, CBP apprehended over 35,000 children. That number almost doubled to 66,127 in FY 2014, with Central American children outnumbering their Mexican counterparts for the first time. Research has identified high levels of violence perpetrated by gangs and drug cartels in the Northern Triangle countries and Mexico as a primary reason for this surge. Under the William Wilberforce Trafficking Victims Protection Reauthorization Act (TVPRA passed with bi-partisan support in 2008, children from Central America cannot be immediately deported and must be given a court hearing.In contrast, unless there are indicia of trafficking, Mexican children are returned immediately to their country. Advocates have expressed concern that expedited removal of Mexican children places children with valid humanitarian claims at risk of being returned to harm, including forcible recruitment into drug cartels and trafficking rings. After the spike in arrivals in FY 2014, several members of Congress called for a change in the TVPRA, urging that Central American children be treated like Mexican children and undergo expedited procedures for their removal. Many of their constituents supported such measures. The Obama administration requested additional funds to strengthen border security, speed up deportation procedures and implement measures to address the humanitarian crisis in Central America. Groups and individuals across the country came together to provide shelter, medical and psychological care and legal representation to many

    Annual sediment delivery by the Ganges and Brahmaputra rivers to the Bengal margin has kept pace with sea level rise since the mid Holocene, sustaining subaerial growth of the delta. However, the Sundarbans region of the tidal delta is disconnected from major distributary sources of sediment and is often thought to be sediment starved, eroding, and susceptible to the meter of sea level rise predicted for the 21st century. Despite these assumptions, direct sedimentation measurements on the tidal delta plain reveal widespread mean annualized accretion rates of ˜1.1 cm yr-1, although heterogeneous depositional patterns indicate that topography and internal creek networks influence local sediment distribution. Short-lived radioisotope inventories (7Be: t1/2 = 53.3 days) measured on the freshly accumulated sediments indicate that about ½ of the mass deposited on the lower delta was sourced directly from the seasonal flood pulse of the river; the remaining ½ is derived from older (≥1 yr) reworked sediments. Net sedimentation on this part of the delta traps ˜10% of annual Ganges-Brahmaputra sediment load, with accretion rates roughly equivalent to the mean regional rate of relative sea-level rise (RSLR) of ˜1.0 cm yr-1. If these sedimentation rates are representative of longer-term trends and subsidence rates remain stable over the next century, the lower delta plain may continue to maintain its elevation and stability despite documented mangrove retreat around its seaward edges.

  18. Ganges Chasma Landing Site: Access to Sand Sheets, Wall Rock and Layered Mesa Material

    The floor of Ganges Chasma offers an ideal landing site for the MSP 2001 lander. This site is exquisite both in terms of engineering constraints and science objectives. The floor of Ganges Chasma is mantled with an extensive sand sheet. Sand sheets develop in conditions which are unfavorable for dune formation. These may include a high water table, periodic flooding, surface cementation, and coarse grained sands. The most extensive sand sheets on Earth are located in the eastern Sahara. These sheets have a relief of less than 1 m over wide areas and total thickness ranges from a few cm to 10 m. The surfaces of sand sheets are composed of granule to pebbly lag deposits. Sand sheets provide an extremely safe landing site and have very low relief. The safety concerns regarding slopes, rocks, and dust would be alleviated by the sand sheet. Furthermore, this vast sand sheet would allow the Marie Curie Rover to cover great distances. Rover navigability would be very easily compared to the tedious rock avoidance maneuvers that Sojourner had to accomplish. This exercise would be an important precursor test for the more capable Athena Rover which will execute longer traverses. Moreover, the Rover has already been "field tested" on sand at the JPL Mars sandbox. Dust should not be a problem: Thermal inertia is 7.7 to 8.9 cgs units. This site satisfies all engineering constraints.

    The most difficult water resources management challenge in the Ganges Basin is the imbalance between water demand and seasonal availability. More than 80 % of the annual flow in the Ganges River occurs during the 4-month monsoon, resulting in widespread flooding. During the rest of the year, irrigation, navigation, and ecosystems suffer because of water scarcity. Storage of monsoonal flow for utilization during the dry season is one approach to mitigating these problems. Three conjunctive use management strategies involving subsurface water storage are evaluated in this study: Ganges Water Machine (GWM), Pumping Along Canals (PAC), and Distributed Pumping and Recharge (DPR). Numerical models are used to determine the efficacy of these strategies. Results for the Indian State of Uttar Pradesh (UP) indicate that these strategies create seasonal subsurface storage from 6 to 37 % of the yearly average monsoonal flow in the Ganges exiting UP over the considered range of conditions. This has clear implications for flood reduction, and each strategy has the potential to provide irrigation water and to reduce soil waterlogging. However, GWM and PAC require significant public investment in infrastructure and management, as well as major shifts in existing water use practices; these also involve spatially-concentrated pumping, which may induce land subsidence. DPR also requires investment and management, but the distributed pumping is less costly and can be more easily implemented via adaptation of existing water use practices in the basin.

    Prior research has demonstrated that both adolescent gang affiliation and perceived delinquent peer association are important predictors of individual offending. A crucial question is whether and how youth gang affiliation contributes to a spectrum of criminal acts above and beyond the influence of associating with delinquent peers. Using 14 waves of data from the Rochester Youth Developmental Study, an ongoing longitudinal panel study aimed at understanding the causes and consequences of delinquency and drug use in an urban sample of adolescents, the current study employs a relatively new modeling technique-dual trajectory analysis-to illustrate the dynamic relationship between these two measures among 666 male youth. The results suggest that the two measures, while overlapping, may constitute distinct concepts that operate in different ways. The most convincing evidence of gang effects, above and beyond the influence of perceived peer delinquency, is for violent behavior and by extension police arrest. Our findings contribute to developmental research and provide information that informs future gang control efforts.

    Sediment cores from the Ganges-Brahmaputra delta in Bangladesh were examined for sedimentological character, clay mineralogy, elemental trends (C, N, S), and 14C geochronology to develop a model for the sedimentary sequence resulting from lower delta plain progradation in the late Holocene. A widespread facies succession from Muddy Sand to Interbedded Mud records progradation of shoal-island complexes and the transition from subtidal to intertidal conditions. Mangrove-vegetated islands and peninsulas represent the final phase of progradation; a Mottled Mud that is deposited by penetration of turbid coastal water into the mangroves during high water events. Organic matter preservation is generally low (Holocene was influenced by regional subsidence patterns in the tectonically active Bengal Basin, which controlled distributary channel avulsion and migration, and the creation of accommodation space.

    Quantifying human group dynamics represents a unique challenge. Unlike animals and other biological systems, humans form groups in both real (offline) and virtual (online) spaces-from potentially dangerous street gangs populated mostly by disaffected male youths to the massive global guilds in online role-playing games for which membership currently exceeds tens of millions of people from all possible backgrounds, age groups, and genders. We have compiled and analyzed data for these two seemingly unrelated offline and online human activities and have uncovered an unexpected quantitative link between them. Although their overall dynamics differ visibly, we find that a common team-based model can accurately reproduce the quantitative features of each simply by adjusting the average tolerance level and attribute range for each population. By contrast, we find no evidence to support a version of the model based on like-seeking-like (i.e., kinship or "homophily").

  7. Evidence for extensive olivine-rich basalt bedrock outcrops in Ganges and Eos chasmas, Mars

    Several localized outcrops of olivine-enriched bedrock have been previously identified in the Ganges and Eos Chasma area on the eastern end of Valles Marineris with the Thermal Emission Imaging System multispectral images. These outcrops form a layer in the walls of Ganges Chasma and appear to be the remnants of a once continuous unit, which was mapped over ~100 km. In this study we further characterize the composition (forsterite content of ~0.68), olivine abundance (10 to >15%), thermal inertia (>600 JK-1 m-2 s-1/2, consistent with in-place rocky material), vertical dimension (~60 to ~220 m), extent (>1100 km laterally), volume (~9.9 × 104 km3), dip (~0.013°NE), and continuity of this layer utilizing Thermal Emission Spectrometer hyperspectral, Thermal Emission Imaging System multispectral, and Mars Orbiter Laser Altimeter elevation data. Morphologic data from high-resolution imagery display a relatively unmantled, rough, and pitted surface associated with the olivine-enriched material, consistent with thermal inertia data. Four possibilities for the origin of the olivine-enriched unit are (1) volcanism associated with tectonic rifting of the Valles Marineris system, (2) a volcaniclastic flow deposit, (3) an intrusive mafic sill, or (4) a discrete episode in Martian history during which flood lavas were erupted onto the surface. The most likely origin is an eruptive event consisting of compositionally uniform flood lavas originating from a primitive mantle source region, possibly associated with the initiation of Tharsis volcanism. This unit is one of the largest continuous compositional units found on Mars and is strikingly similar to other olivine-enriched deposits identified in previous studies where compositional, morphologic, and thermophysical similarities are observed. These similarities may indicate that there was a period in early Martian history, where compositionally uniform and extensive olivine-enriched flood basalts were erupted on the Martian

    Rivers have no regard for human demarcated boundaries. Besides, ever increasing demand-supply gap & vested riparian interests, fuel transboundary water conflicts. For resolving such disputes, appropriation doctrines advocating equity & fairness have received endorsement in the Helsinki Rules-1966 & UN Convention-1997. Thus, current study proposes the principle of equitable apportionment for sharing Ganges waters as it balances the interests & deservedness of all stakeholders, namely, India & its 11 states, Bangladesh, Nepal, & China. The study endeavors to derive a reasonable share of each co-basin state by operationalizing the vague concepts of fairness & equity through an objective & quantitative framework encompassing proportionality & egalitarianism for distributive & procedural justice. Equal weightage factors reflecting hydrology, geography & water use potential are chosen for fair share computation, wherein each contender ranks these factors to maximize his entitlement. If cumulative claims exceed the water availability, each claimant puts forth next ranked factor & this process continues till the claims match availability. Due to inter-annual variability in few factors, scenarios for Rabi & Kharif seasons are considered apart from cases for maximum, upper quartile, median, lower quartile & minimum. Possibility of spatial homogeneity & heterogeneity in factors is also recognized. Sometimes lack of technical information hinders transboundary dispute resolution via legal mechanisms. Hence, the study also attempts to bridge this gap between law & technology through GIS-based SWAT hydrologic model by estimating the Ganges water yield, & consequent share of each riparian for range of flows incorporating e-flows as well, under present & future climate & landuse scenarios. 82% of India's territory lies within interstate rivers, & therefore this research is very pertinent as it can facilitate the decision makers in effective interstate water conflict resolution.

  9. Detecting Long-term Trend of Water Quality Indices of Dong-gang River, Taiwan Using Quantile Regression

    2013-12-01

    ABSTRACT BODY: Abstract Surface water quality is an essential issue in water-supply for human uses and sustaining healthy ecosystem of rivers. However, water quality of rivers is easily influenced by anthropogenic activities such as urban development and wastewater disposal. Long-term monitoring of water quality can assess whether water quality of rivers deteriorates or not. Taiwan is a population-dense area and heavily depends on surface water for domestic, industrial, and agricultural uses. Dong-gang River is one of major resources in southern Taiwan for agricultural requirements. The water-quality data of four monitoring stations of the Dong-gang River for the period of 2000-2012 are selected for trend analysis. The parameters used to characterize water quality of rivers include biochemical oxygen demand (BOD), dissolved oxygen (DO), suspended solids (SS), and ammonia nitrogen (NH3-N). These four water-quality parameters are integrated into an index called river pollution index (RPI) to indicate the pollution level of rivers. Although widely used non-parametric Mann-Kendall test and linear regression exhibit computational efficiency to identify trends of water-quality indices, limitations of such approaches include sensitive to outliers and estimations of conditional mean only. Quantile regression, capable of identifying changes over time of any percentile values, is employed in this study to detect long-term trend of water-quality indices for the Dong-gang River located in southern Taiwan. The results show that Dong-gang River 4 stations from 2000 to 2012 monthly long-term trends in water quality.To analyze s Dong-gang River long-term water quality trends and pollution characteristics. The results showed that the bridge measuring ammonia Long-dong, BOD5 measure in that station on a downward trend, DO, and SS is on the rise, River Pollution Index (RPI) on a downward trend.

    This study tested a transactional hypothesis predicting early adult sexual coercion from family maltreatment, early adolescent gang affiliation, and socialization of adolescent friendships that support coercive relationship norms. The longitudinal study of a community sample of 998 11-year-olds was intensively assessed in early and middle adolescence and followed to 23-24 years of age. At age 16-17 youth were videotaped with a friend, and their interactions were coded for coercive relationship talk. Structural equation modeling revealed that maltreatment predicted gang affiliation during early adolescence. Both maltreatment and gang affiliation strongly predicted adolescent sexual promiscuity and coercive relationship norms with friends at age 16-17 years. Adolescent sexual promiscuity, however, did not predict sexual coercion in early adulthood. In contrast, higher levels of observed coercive relationship talk with a friend predicted sexual coercion in early adulthood for both males and females. These findings suggest that peers have a socialization function in the development of norms prognostic of sexual coercion, and the need to consider peers in the promotion of healthy relationships.

Our familiarity with plastics makes polymers ideal examples of chemicals for discussion in K-12 science classes. Most importantly, polymers can be used as examples of chemicals that are safe to handle and of obvious use to society. The structures of polymers are easily represented by a number of models. These simple models go a long way in explaining the familiar physical properties of plastics. However, the introduction of polymers in the classroom relies on the availability of teaching material, experiments, and demonstrations that illustrate concepts in the current science curriculum. Chain Gang-The Chemistry of Polymers, one of the Science in Our World series published by the Center for Chemical Education at Miami University-Middletown (Ohio), will serve as a great resource for teachers interested in providing their students with a series of activities that can be related to their everyday experiences with these ubiquitous chemicals. After a brief introduction to some basic concepts, the book presents a series of 23 experiments. The collection of experiments presented here spans illustrations of chemistry, physical properties, analysis, and processing. Each experiment is recommended as either a hands-on activity or demonstration for various grade levels. A guide for the teacher suggests how the experiment can be used to illustrate topics in the science curriculum. The materials required for each activity are listed in detail, with quantities and sources (all materials are available from Flinn Scientific or hardware stores). There are detailed instructions for preparation of each experiment and how to introduce the experiment to students, and step-by-step instructions for activity. Very importantly, safety and disposal issues are clearly presented. Suggestions for cross-curriculum integration are also

  16. River avulsions in the presence of tectonic tilting, and the Ganges-Brahmaputra Delta

    In Bangladesh, the set of active rivers of the Ganges-Brahmaputra Delta overlie a landscape that is being continually modified by tectonics. The response of rivers to a surface being altered by tectonic tilting or other causes of spatially variable subsidence is generally understood to be a preferred path direction toward regions of higher subsidence. Quantifying the magnitude of the effect of variable subsidence on the timescale and path direction of channel avulsion remains, however, an open question. Recent experimental work has suggested an equilibrium-slope explanation for the timescale and conditions for avulsion, which provides a way forward on understanding how varied subsidence conditions would affect the avulsion process. Here we adapt this model for avulsion to the context of variable subsidence, developing a new framework to quantify its effect on channel avulsions. We find that variable subsidence results in two effects: differing timescales between avulsions on different parts of the delta, and differing frequencies of avulsion to these locations. Regions of higher subsidence both draw avulsions more frequently, and result in longer channel residence times in these locations. We also describe the effect of incision or aggradation due to sea level changes within this framework: incisional events lengthen avulsion timescales everywhere on the delta, while periods of sea-level rise drive the timescales back toward their minimum values. Finally, we apply this theory to the Ganges-Brahmaputra Delta, where we use a map of regional variable subsidence that we derived from GPS and published stratigraphic data, to predict the variation in avulsion timescale and frequency for the Brahmaputra River due to this variable subsidence. We make estimates for two different tectonic history interpretations, and for the cases with or without the estimated incision from the most recent sea-level fall.

    The Ganges-Brahmaputra river delta, with 170 million people and a vast, low-lying coastal plain, is perceived to be at great risk of increased flooding and submergence from sea-level rise. However, human alteration of the landscape can create similar risks to sea-level rise. Here, we report that islands in southwest Bangladesh, enclosed by embankments in the 1960s, have lost 1.0-1.5 m of elevation, whereas the neighbouring Sundarban mangrove forest has remained comparatively stable. We attribute this elevation loss to interruption of sedimentation inside the embankments, combined with accelerated compaction, removal of forest biomass, and a regionally increased tidal range. One major consequence of this elevation loss occurred in 2009 when the embankments of several large islands failed during Cyclone Aila, leaving large areas of land tidally inundated for up to two years until embankments were repaired. Despite sustained human suffering during this time, the newly reconnected landscape received tens of centimetres of tidally deposited sediment, equivalent to decades’ worth of normal sedimentation. Although many areas still lie well below mean high water and remain at risk of severe flooding, we conclude that elevation recovery may be possible through controlled embankment breaches.

    Impact of climate change on the hydrology of the Ganges River Basin (GRB) is simulated by using a hydrological model - Soil and Water Assessment Tool (SWAT). Climate data from the GCM, Hadley Centre Coupled Model, version 3 (HadCM3) was downscaled with PRECIS for the GRB under A1B Special Report on Emission Scenarios (SRES) scenarios. The annual average precipitation will increase by 2.2% and 14.1% by 2030 and 2050, respectively, compared to the baseline period (1981-2010). Spatial distribution of the future precipitation shows that in the substantial areas of the middle part of the GRB, the annual precipitation in 2030 and 2050 will be reduced compared to the baseline period. Simulations indicate that in 2050 the total groundwater recharge would increase by 12%, while the increase of evapotranspiration will be about 10% compared to the baseline period. The water yield is also expected to increase in the future (up to 40% by 2050 compared to baseline), especially during the wetter months. The model setup is available for free from IWMI's modelling inventory.

    Full Text Available The recently endorsed Sustainable Development Goals (SDGs agenda unanimously agrees on the need to focus on inclusive development, the importance of eradicating extreme poverty and managing often complex human well-being impacts of rapid urban growth. Sustainable and inclusive urbanisation will accelerate progress towards the SDGs and contribute to eradicating extreme poverty. In tropical delta regions, such as the Ganges Brahmaputra Meghna delta region, urban growth and resulting intra-urban inequalities are accelerated by the impact of environmental and climate change. In this context, the present study uses the 2010 Household Income and Expenditure Survey to analyse the extent of wealth-based inequalities in human well-being in the urban delta region and the determinants of selected welfare measures. The results suggest that the extent of intra-urban inequalities is greatest in educational attainment and access to postnatal healthcare and relatively low in the occurrence of gastric disease. The paper concludes by providing policy recommendations to reduce increasing wealth inequalities in urban areas, thus contributing to sustainable development of the region.

    Full Text Available Outlaw motorcycle gangs (OMGs are an iconic element of the criminal landscape in the United States, the country of their origin. Members of OMGs may present to the emergency department (ED as a result of motor vehicle accidents or interpersonal violence. When one member of an OMG is injured, other members and associates are likely to arrive in the ED to support the injured member. The extant literature for ED personnel lacks an overview of the culture of OMGs, a culture that promotes the display of unique symbols and that holds certain paraphernalia as integral to an outlaw biker’s identity and pride. The objective of this manuscript is to discuss various aspects of the culture of OMGs so that ED personnel may better understand the mentality of the outlaw biker. Knowledge of their symbols, values, and hierarchy can be crucial to maintaining order in the ED when an injured outlaw biker presents to the ED. We used standard search engines to obtain reports from law enforcement agencies and studies in academic journals on OMGs. We present the observations of 1 author who has conducted ethnographic research on outlaw bikers since the 1980s.

    Major part of the Holocene Ganges-Brahma-putra delta occupies the southern and southwestern part of Bangladesh with a smaller part extending beyond the international boundary in the west. Five facies assemblages are documented in the lower deltaic plain in five different depositional environments: levee or levee complex, bil or depression, abandoned meander belt, interdistributary plain and estuarine plain. The thickness of the Holocene sediments ranges from 30 m to 70 m in the deltaic plain, usually floored by the Pleistocene stiff clays, with the excep-tion" of the abandoned meander belt deposit where Holocene channel sand deposited directly on thePleistocene sand. Radiocarbon dates indicate that low-rate sedimentation has occurred in the northern part, where 4-6 m thick sediments were deposited since the mid-Holocene, whereas 10-30 m thick sediments were deposited in the southern part during the same span of time. In addi-tion, significant coastal subsidence (3 mm/a on average), added by sea-level rise (1.5 mm/a, conservative rate) occurs in the study area, which serves as a negative factor in degrading the coastal plain of Bangladesh in the future, while taking into consideration the weaker sedimentation in the area.

    Deltas provide diverse ecosystem services and benefits for their populations. At the same time, deltas are also recognised as one of the most vulnerable coastal environments, with a range of drivers operating at multiple scales, from global climate change and sea-level rise to deltaic-scale subsidence and land cover change. These drivers threaten these ecosystem services, which often provide livelihoods for the poorest communities in these regions. The imperative to maintain ecosystem services presents a development challenge: how to develop deltaic areas in ways that are sustainable and benefit all residents including the most vulnerable. Here we present an integrated framework to analyse changing ecosystem services in deltas and the implications for human well-being, focussing in particular on the provisioning ecosystem services of agriculture, inland and offshore capture fisheries, aquaculture and mangroves that directly support livelihoods. The framework is applied to the world's most populated delta, the Ganges-Brahmaputra-Meghna Delta within Bangladesh. The framework adopts a systemic perspective to represent the principal biophysical and socio-ecological components and their interaction. A range of methods are integrated within a quantitative framework, including biophysical and socio-economic modelling and analyses of governance through scenario development. The approach is iterative, with learning both within the project team and with national policy-making stakeholders. The analysis is used to explore physical and social outcomes for the delta under different scenarios and policy choices. We consider how the approach is transferable to other deltas and potentially other coastal areas.

    Sedimentology, carbon isotope and sequence stratigraphic analysis of subsurface sediments from western part of Ganges-Brahmaputra (GB) delta plain shows that a Late Quaternary marine clay and fluvial channel-overbank sediments of MIS 5 and 3 highstands are traceable below the Holocene strata. During the Last Glacial Maximum (LGM) sea-level lowering of >100 m produced a regional unconformity (type 1), represented by palaeosols and incised valley. C4 vegetation expanded on exposed lowstand surface in an ambient dry glacial climate. At ˜9 ka transgression inundated the lowstand surface pushing the coastline and mangrove front ˜100 km inland. Simultaneous intensification of monsoon and very high sediment discharge (˜4-8 times than modern) caused a rapid aggradation of both floodplain and estuarine valley fill deposits between 8 and 7 ka. The Hoogli River remaining along its present drainage possibly acted as the main conduit for transgression and sediment discharge that was subsequently abandoned. C3 vegetation dominated the delta plain during this time. From 7 ka onward progradation of delta plain started and continued till recent. This period experienced a mixed C3-C4 vegetation with localized mangroves in the mid-Holocene to dominant return of C4 vegetation in the late Holocene period. The study indicates that while the initiation of western part of GB delta occurred at least 1 ka earlier than the global mean delta formation age, the progradation started at ˜7 ka, at least 2 ka earlier than thought before. The terrestrial vegetation change was modulated by changes in depositional environment, specific ecological niches and climate rather than pCO 2.

    Full Text Available Direct measurement of absorbed dose rate in air due to exposure from outdoor terrestrial γ radiation and assessment of consequent public health hazard continues to be of environmental and public concern. Present study was aimed to establish a baseline data of annual effective dose and to assess the associated health risk from outdoor terrestrial γ radiation along the river Alaknanda and Ganges of India. Terrestrial γ radiation exposure doses (excluding cosmic radiation were measured using a Plastic Scintillation Counter. Absorbed dose rates in air were measured at eight designated locations from Nandprayag to Allahabad along the river. From the average absorbed dose rates, annual effective dose (AED and excess life time cancer risks (ELCR were calculated by standard method. Results showed that absorbed dose rates in air ranged between 81.33 ± 2.34 nSv.h−1 and 144 ± 5.77 nSv.h−1 and calculated AED ranged between 0.10 ± 0.012 mSv.y−1 to 0.18 ± 0.007 mSv.y−1 at the designated locations along these rivers. Calculated ELCR were found in the range of 0.375 × 10−3 to 0.662 × 10−3. Present study measured the outdoor γ radiation levels along the rivers. The calculated annual effective doses and life time cancer risk were found higher than the world average value at higher altitudes. But the measured doses and calculated risks at plains were close to that of reported average values.

  6. Optical Performance and Weight Estimation of a Heliostat with Ganged Facets

    In standard heliostat design the usual strategy of cost reduction is to increase the mirror area of the heliostats. This leads to a reduction of specific drive cost, but also to an increase of the torques caused by the wind loads, resulting in higher specific weight and higher specific drive power. The opposite strategy focuses on the reduction of the specific weight and driving power. Therefore the mirror area is decreased. In total the drive power is much lower then, but it has to be divided into more units which means a drawback for cost reduction. A combination of both strategies is to couple small heliostats so that they can be tracked by the same drive. At the Torque Tube Heliostat (TTH) the mirrors are mounted on torque tubes to simplify the coupling mechanism for the elevation angle. The optimal tracking speed of heliostats depends on the position in the field. In a heliostat with ganged facets all facets are tracked with the same speed. This leads to higher astigmatism losses compared to independently tracked mirrors. To reduce shading a certain space is foreseen between the facets of the TTH. To achieve a high mirror density and to avoid too long and therefore too flexible torque tubes this distance is limited. Thus the shading is higher than usually. Ray tracing calculations were done to obtain optimized heliostat configurations and to estimate the energy yield of a heliostat field built of 288 square meters TTHs. The results are compared to a conventional heliostat field. To get an idea of the weight reduction potential of the TTH the dimensions of the torque tube, the secondary axis tube and the mirror support structure were weight optimized via FEM. The layout criterion was a mean mirror error of 5 mrad under a wind load and gravity, which was calculated from the deviations of the FE model. (Author)

    In low and middle-income countries, many deltaic communities directly depend on the natural environment for income and well-being. Current environmental concerns that threaten deltaic communities, such as increasing salinity, sedimentation, erosion and subsidence are likely to be exacerbated by climate change and variability, for example sea-level rise, increased storminess and rising temperatures. Such changes, along with other social and environmental stressors, mean that communities must adapt. This paper outlines findings of a systematic review of the peer-reviewed and grey literature that examines observed adaptations in three deltas of differing sizes in various geographical contexts: the Ganges-Meghna-Brahmaputra in India and Bangladesh, the Mahanadi in India, and the Volta in Ghana. It compares and contrasts various elements of observed adaptations, including who is driving the adaptation, the beneficiaries, barriers to participation and evidence for maladaptation. The predominant drivers of adaptation vary from government (at state level in India and national level in Bangladesh) and NGOs (in Ghana). Autonomous adaptations are not widely reported in the literature from any of the deltas. In all three deltas there is a focus on supporting adaptation in farming rather than fishing; despite the fact that fisheries contribute to local food security as well as national economies. Lack of access to financial, natural, physical and human capital are common barriers to adaptation in all three deltas. Additionally the Indian literature in particular highlights the lack of coordination between different government departments, coupled with an excessively top-down (state-driven) approach to adaptation. Maladaptation is most commonly reported in the literature from Bangladesh, for example, loss of employment of inland fishermen in embanked areas. The paper concludes by highlighting some of the implications of these findings for adaptation policy in deltas.

    The Ganges-Brahmaputra-Meghna (GBM) River Basin presents a spatially diverse hydrological regime due to it's complex topography and escalating demand for freshwater resources. This presents a big challenge in applying the current state-of-the-art regional climate models (RCMs) for climate change impact studies in the GBM River Basin. In this study, several RCM simulations generated by RegCM4.4 and PRECIS are assessed for their seasonal and interannual variations, onset/withdrawal of the Indian monsoon, and long-term trends in precipitation and temperature from 1982 to 2012. The results indicate that in general, RegCM4.4 and PRECIS simulations appear to reasonably reproduce the mean seasonal distribution of precipitation and temperature across the GBM River Basin, although the two RCMs are integrated over a different domain size. On average, the RegCM4.4 simulations overestimate monsoon precipitation by {˜ }26 and {˜ }5% in the Ganges and Brahmaputra-Meghna River Basin, respectively, while PRECIS simulations underestimate (overestimate) the same by {˜ }7% ({˜ }16% ). Both RegCM4.4 and PRECIS simulations indicate an intense cold bias (up to 10°C) in the Himalayas, and are generally stronger in the RegCM4.4 simulations. Additionally, they tend to produce high precipitation between April and May in the Ganges (RegCM4.4 simulations) and Brahmaputra-Meghna (PRECIS simulations) River Basins, resulting in early onset of the Indian monsoon in the Ganges River Basin. PRECIS simulations exhibit a delayed monsoon withdrawal in the Brahmaputra-Meghna River Basin. Despite large spatial variations in onset and withdrawal periods across the GBM River Basin, the basin-averaged results agree reasonably well with the observed periods. Although global climate model (GCM) driven simulations are generally poor in representing the interannual variability of precipitation and winter temperature variations, they tend to agree well with observed precipitation anomalies when driven by

    We examine gender and meanings of risk in interviews (2007-2010) with gang-involved young men and women (n = 253) engaged in illicit drug sales in San Francisco, California. The in-depth interviews from this NIDA-funded study were coded using the software NVivo to identify patterns and themes. We examine their interpretations of the risks of drug-selling and their narratives about gender differences in these risks. We find distinct discourses regarding the role of femininities and masculinities and male and female bodies in shaping risk as well as the nexus between gender, family, and risk for female drug sellers.

    , the results from the method developed in this study involving virtual stations show that the CryoSat-2 data can indeed be used for such monitoring by utilizing the high spatial coverage and the sub-cycle period of 30 days. The results show that it is possible to capture the peak flow occurring during late...... larger differences. For five virtual stations in the Brahmaputra River, the mean difference between the obtained amplitudes is similar to 10 cm, whereas the mean phase difference is less than 2.7 days.

    The MERRA Aerosol Reanalysis (MERRAero) has been recently developed at NASA's Global Modeling Assimilation Office. This reanalysis is based on a version of the Goddard Earth Observing System-5 (GEOS-5) model radiatively coupled with Goddard Chemistry, Aerosol, Radiation, and Transport aerosols, and it includes assimilation of bias-corrected aerosol optical thickness (AOT) from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on both Terra and Aqua satellites. In October over the period 2002-2009, MERRAero showed that AOT was lower over the east of the Ganges basin than over the northwest of the Ganges basin: this was despite the fact that the east of the Ganges basin should have produced higher anthropogenic aerosol emissions because of higher population density, increased industrial output, and transportation. This is evidence that higher aerosol emissions do not always correspond to higher AOT over the areas where the effects of meteorological factors on AOT dominate those of aerosol emissions. MODIS AOT assimilation was essential for correcting modeled AOT mainly over the northwest of the Ganges basin, where AOT increments were maximal. Over the east of the Ganges basin and northwest Bay of Bengal (BoB), AOT increments were low and MODIS AOT assimilation did not contribute significantly to modeled AOT. Our analysis showed that increasing AOT trends over northwest BoB (exceeding those over the east of the Ganges basin) were reproduced by GEOS-5, not because of MODIS AOT assimilation butmainly because of the model capability of reproducing meteorological factors contributing to AOT trends. Moreover, vertically integrated aerosol mass flux was sensitive to wind convergence causing aerosol accumulation over northwest BoB.

    Yellow River water transfer for Tianjin is important in solving the water shortage in Tianjin, which facilitate economic development and social progress for many years. Fresh water drawn from Yellow River(i. e., Yin-Huang water) becomes saltier and saltier when being stored in the Bei-Da-Gang reservoir. We qualitatively analyze the water salinization mechanism based on mass transfer theory. The main factors are salinity transfer of saline soil, evaporation concentrating, and the agitation of wind. A simulative experimental pond and an evaporation pond were built beside the Bei-Da-Gang reservoir to quantitatively investigate the water salinization based on water and solute balance in the simulative pond. 80% of increased [Cl- ] is due to the salinity transfer of the saline soil and the other 20% is due to evaporation concentrating, so the former is the most important factor. We found that the salinization of Yin-Huang water can be described with a zero-dimension linear model.

    This research examined whether negative peer influences (i.e., norms favoring risky sex and drug use and gang involvement) mediated the relationship between school engagement (i.e., grade point averages [GPAs] obtained from school records and student-teacher connectedness) and sexual behaviors (i.e., sexual début, sex without condoms, group sex, and sex while using drugs) among African American high school adolescents, and whether these relationships varied by gender. Five hundred sixty-three high school adolescents (ages 13 to 19) completed self-administered questionnaires that assessed school engagement markers (GPAs obtained from student records, and student-teacher connectedness), peer influences, sexual début, and risky sex (sex without condoms, group sex, and sex while using drugs). Major findings for boys indicate that GPA was negatively associated with both sexual début and risky sex. Additionally, the relationship between student-teacher connectedness and risky sex was mediated by gang involvement. For girls, higher GPAs were associated with fewer norms favoring risky sex and drug use and such norms were associated with sexual début. Moreover, the relationship between GPA, sexual début and risky sex was mediated by risky peer norms. Intervention programs to delay sexual début and reduce risky sex among youths should attend to the gendered ways through which such behaviors occur.

    We report on metalorganic vapor phase epitaxy (MOVPE) of distributed Bragg reflectors (DBR) applying a periodic modulation of the GaN doping concentration only. The doping modulation changes the refractive index of GaN via the Burstein-Moss-effect. MOVPE growth of highly doped GaN:Ge and modulation of the dopant concentration by at least two orders of magnitude within few nanometers is required to achieve a refractive index contrast of 2-3%. Such modulation characteristic is achieved despite the presence of Ge memory effects and incorporation delay. We realized DBRs with up to 100 layer pairs by combining GaN:Ge with a nominal doping concentration of 1.6×1020 cm-3 as low-refractive index material with unintentionally doped GaN as high-refractive index layer. Scanning transmission electron microscope images reveal DBR structures with abrupt interfaces and homogenous layer thicknesses in lateral and vertical direction. Reflectance measurements of DBRs designed for the blue and near UV-spectral region show a narrow stopband with a maximum reflectivity of 85% at 418 nm and even 95% at 370 nm. InGaN/GaN multi-quantum well structures grown on top of such DBRs exhibit narrow emission spectra with linewidths below 3 nm and significantly increased emission intensity.

    We seek to understand spatiotemporal (ST) patterns of agricultural land cover dynamics on the lower Ganges-Brahmaputra Delta (GBD). Recent availability of accurately coregistered, radiometrically intercalibrated Landsat TM, ETM+ and OLI imagery collected since 1988 allows for synoptic scale ST analyses of vegetation phenology. We use multitemporal spectral mixture analysis of exoatmospheric reflectance to represent land cover and water bodies as continuous fields of soil and sediment substrates (S), vegetation (V), and dark surfaces (D; water & shadow). This study analyses 61 cloud-free Landsat acquisitions across two geographic scenes to identify ST patterns of winter cropping and interconversion between agricultural fields and ponds used for aquaculture. We also use MODIS 16-day EVI composite time series post-2000 and high spatial resolution imagery to extend and vicariously validate the Landsat-derived observations. We use temporal moment spaces (derived from temporal mean, standard deviation, and skewness) and temporal feature spaces (derived from spatial Principal Components) to characterize the full range of phenological patterns observed at 30 m scales throughout the lower delta. For each year with sufficient cloud-free coverage, we distinguish between areas with a high likelihood of use for aquaculture versus areas with a high likelihood of use for agriculture based on a combination of reflectance and phenology. From changes in these patterns we infer changes in land use on seasonal to interannual timescales. Many of the phenological patterns we observe occur on the scale of individual polders, suggesting decision making at community scales. While there appears to be considerable loss of agricultural land to aquaculture in many areas of the lower delta, we also observe intensification of dry season cropping in other areas. MODIS reveals frequent instances of both gradual and abrupt decreases in seasonal peak EVI as well as many localized instances of abrupt

    Transdisciplinary science transcends disciplinary boundaries. The reasons to engage in transdisciplinary science are many and include the desire to nurture a more direct relationship between science and society, as well as the desire to explain phenomena that cannot be explained by any of the existing disciplinary bodies of knowledge in isolation. Both reasons also reinforce each other, as reality often features a level of complexity that demands and inspires the combination of scientific knowledge from various disciplines. The challenge in transdisciplinary science, however, is not so much to cross disciplinary boundaries, but to ensure an effective connection between disciplines. This contribution reports on the strategy used in a transdisciplinary research project to address groundwater management in peri-urban areas in the Ganges delta. Groundwater management in peri-urban areas in rapidly urbanizing deltas is affected by diverse forces such as rapid population growth, increased economic activity and changing livelihood patterns, and other forces which result in a growing pressure on available groundwater resources. Understanding the intervention possibilities for a more sustainable groundwater management in these peri-urban areas requires an understanding of the dynamic interplay between various sub-systems, such as the physical groundwater system, the water using activities in households and livelihoods, and the institutional system of formal and informal rules that are used by various parties to access groundwater resources and to distribute the associated societal and economic costs and benefits. The ambition in the reported project is to contribute both new scientific knowledge, as well as build capacity with peri-urban stakeholders to improve the sustainability and equitability of local groundwater management. This is done by combining science and development activities, led by different organizations. The scientific component further consists of three

    The Ganges Alluvial Plain ('GAP') is the sedimentary infill of the foreland basin created during Himalayan orogeny. Freshly eroded material from the Himalaya and southern cratonic tributaries is deposited into a system with long water-sediment interaction times, creating potential for further generation of river weathering fluxes. To quantify weathering processes in the GAP, 51 sites including all major tributaries were sampled in a September 2013 campaign and analysed for major and minor ions, Ge/Si ratios and δ30Si, δ13C and δ18O. Net dissolved Si (DSi) and major cation yields are 2 to 5 times lower in the GAP than the Himalaya, and at a whole basin scale approximate the global average, indicating that the plain apparently moderates the efficiency of Himalayan weathering rates. Mainstem δ30Si spans 0.81 to 1.93‰ (see figure) and gives the impression of a system buffered to moderate DSi and δ30Si. Ge/Si ratios (µmol/mol) are higher than expected in the Himalaya (>3), reflecting input of Ge-enriched water from hot springs, and decline to ~1.4 in the GAP. For the Himalayan sourced rivers, δ30Si increases with distance from the Himalayan front, and can not be explained entirely by conservative mixing with higher δ30Si peninsular and GAP streams. To a first degree, the δ30Si data suggest incorporation of Si into secondary minerals as the key fractionating process, and that this occurs both in situ during initial weathering and progressively in the GAP. Partitioning of solutes between sources is complicated in the GAP. Consistent with previous work, carbonate weathering dominates the ion fluxes, but with substantial contributions from saline/alkaline soil salts, the chlorination of wastewater and highly variable rainfall chemistry. Due to these contributions, precisely inferring the input from silicate weathering is difficult. We introduce a novel method to infer silicate-weathering rates that exploits the fractionation of Si during clay formation to account

    Research has found that among juveniles weak ties to informal social control entities such as parents, school, and conventional peers increase the probability of the initiation and continuation of deviant behaviors such as drug use and crime. Given the weak ties of formal social control mechanisms in highly disadvantaged communities, informal social control mechanisms are often an important deterrent that reduce or moderate engagement in deviant behaviors among serious and persistent offenders. This analysis examines the association between long-term gang membership and adolescent informal social control processes, drug use, and delinquency. This research is based on data from a study of 160 Mexican American male gang members between the ages of 16 and 20. Findings suggest that among gang members in this context, commonly studied informal control mechanisms such as the family and schools do not function to deter long-term gang membership that is associated with serious criminal and violent behavior and drug use. The implications for future research on desistance or continuation of antisocial behavior across the life course are discussed.

    A longitudinal study (15years) investigates heroin use patterns following precocious transition experiences for gang-affiliated Mexican-American males (n=119) in San Antonio, Texas. Five precocious transitions are examined: cohabitation, early nest leaving, school dropout, teenage parenthood, and unemployment (while not in school). Half of these men used heroin over the follow-up period for an average of under 4years. Findings from a zero-inflated Poisson model indicate that while these transitions do not have a significant effect on initiation of heroin use, they do have an important influence on individual's drug trajectories once they have initiated. Early-nest leaving and teenage parenthood are protective factors for continued heroin use while dropping out of high school and cohabiting during this same period are risk factors. Findings are discussed within the context of these disadvantaged and marginalized communities.

    Full Text Available This paper is dealing with the engineering design of a gang drilling machine with jig & fixtures to make a prototype machine. This effort has been done in order to solve the problem which aroused in small business enterprises producing birdcages. The problem was how to minimize the production time in making a lot of holes that have same distance and straightness. Hopefully, the prototype machine can help the small business enterprises to increase their production rate.The design engineering process has been carried out by variant approximation on dowel pin modular fixtures in order to simplify fixtures design. CAD CAM software has also been used as fixtures synthesized method including geometric analysis and three dimensional fixtures assembling. The resulting prototype machine can be well operated and based on the running test, it can be concluded that the greater the motor rotation the greater the power needed. As for teak wood, at 250 rpm motor rotation the power needed is 26.5 watt, and at 400 rpm the motor needs power of 43.6 watt while at 600 rpm the motor needs power of 600 watt. The power consumption is also depends on the type of material, the better the mechanical properties of the materials, the higher the power consumption. For cast iron, the 400 rpm motor rotation needs power as high as 569.7 watt. This prototype of gang drilling machine needs power of 350 watt to make five holes on teak wood while ordinary drilling machine needs total power of 1350 watt.

Biodiversitas 15: 186-194.The present study describes the analysis and mapping of the different measurements of freshwater fish biodiversity of the Upper Ganges basin in the Himalayan region using spatial interpolation methods of Geographical Information System. The diversity, richness and abundance of fishes for each sampling location were determined and Kriging interpolation was applied on each fisheries measurement to predict and produce semivariogram. The semivariogarms produced were cross validated and reclassified. The reclassified maps for richness, abundance and diversity of fishes, occurrence of cold water threatened fish and abundance of important genera like Tor, Schziothorax and species were produced. The result of the Kriging produced good results and overall error in the estimation process was found significant. The cross validation of semovariograms also provided a better result with the observed data sets. Moreover, weighted overlay analysis of the reclassified raster maps of richness and abundance of fishes produced the classified raster map at different evaluation scale (0-10 qualitatively describing the gradient of species richness and abundance compositely. Similarly, the classified raster map at same evaluation scale qualitatively describing the gradient of species abundance and diversity compositely was produced and published. Further, basin wise analysis between Alaknanda/Pindar and Ganga1 sub basins showed 0.745 disparities at 0.745 distances in 2 dimensional spaces. The richness, diversity and abundance of threatened fishes among the different sampling locations were not significant (p = 0.9.

    Bangladesh is plagued by high concentrations of naturally occurring arsenic (As) in the shallow groundwater of the Ganges-Brahmaputra-Meghna delta (GBMD), leading to widespread poisoning of people in the region. Most of the 156 million people in Bangladesh obtain their drinking water through hand-pumped tube wells that often draw arsenic-contaminated water from shallow, Holocene-age aquifers of the delta. The distribution of arsenic within these aquifers is heterogeneous and linked with the complex stratigraphy of the GBMD through its controls on hydrogeology and aquifer biogeochemistry. This research investigates differences in the fluvio-deltaic deposits formed by the Ganges and Brahmaputra rivers, as well as differences in the tectonic setting across the lower delta plain. Furthermore, we investigate how these overarching controls influence stratigraphic architecture and the resulting aquifer systems, and ultimately the distribution of As within the shallow aquifers of the lower delta plain. To accomplish this, a transect of 55 sediment cores spanning the entire lower delta plain of Bangladesh was drilled to a depth of 90 m. In addition to knowledge of the stratigraphic architecture gained from borehole lithologs, samples from these cores were analyzed for provenance and grain size to determine source of the sediments and the depositional history of the rivers. Relating delta stratigraphy to As distribution was accomplished by measuring groundwater As in 10-20 tubewells within a 1 km radius of each borehole. This data was combined with groundwater data from the Bangladesh Arsenic Mitigation Water Supply Project within 25 km of the transect. Statistical analysis of the groundwater data was then conducted using hierarchical regressions as well as a nearest neighbor algorithm. This study provides a better understanding of Holocene delta evolution and river behavior, as well as a more complete understanding of the geologic controls on As and the characteristics of

    Reviving the Ganges Water Machine (GWM), coined 40 years ago, is the most opportune solution for mitigating the impacts of recurrent droughts and floods in the Ganges River Basin in South Asia. GWM create subsurface storage (SSS) by pumping more groundwater from the aquifers before the monsoon for irrigation and other uses and recharge it during the monsoon. The present study uses fully processed and physically based numerical models, MODFLOW and SWAT, in a semi-coupled modelling framework to examine the technical feasibility of recharging the SSS. The aquifer was simulated as a two-layer system using hydrogeological and groundwater data, model was calibrated from 1999 to 2005 and validated from 2006 to 2010. It assesses the impacts of gradual increase of SSS in 10 years from the base year 2010 under two scenarios (increased rainfall or controlled pumping and recharge) to meet a potential unmet demand of 1.68 billion cubic meters (Bm3) in the Ramganga sub-basin with an area of 18,668 km2. The results show that 3-4 m of subsurface storage can be created by groundwater pumping of 0.25 Bm3/year by 2020. Under the controlled pumping and recharge scenario, groundwater recharge and river seepage could increase by 14% (4.21-4.80 Bm3) and 31% (1.10-1.44 Bm3), respectively. However, baseflow will decrease by 30% (0.18-0.12 Bm3) over the same time period. The results also show that recharge increased 44% (4.21-6.05 Bm3) under an increased rainfall scenario. Simultaneously, river seepage and baseflows would increase 36% (1.10-1.14 Bm3) and 11% (0.18-0.20 Bm3), respectively. A well-designed managed aquifer recharge program is required to eliminate the negative impact of river flows in the low flow season.

    Full Text Available We evaluated the spatial and temporal responses of precipitation in the basins as modulated by the El Niño Southern Oscillation (ENSO and Indian Ocean (IO dipole modes using observed precipitation records at 43 stations across the Ganges and Brahmaputra basins from 1982 to 2010. Daily observed precipitation records were extracted from Global Surface Summary of the Day dataset and spatial and monthly anomalies were computed. The anomalies were averaged for the years influenced by climate modes combinations. Occurrences of El Niño alone significantly reduced (60% and 88% of baseline in the Ganges and Brahmaputra basins, respectively precipitation during the monsoon months in the northwestern and central Ganges basin and across the Brahmaputra basin. In contrast, co-occurrence of La Niña and a positive IO dipole mode significantly enhanced (135% and 160% of baseline, respectively precipitation across both basins. During the co-occurrence of neutral phases in both climate modes (occurring 13 out of 28 yr, precipitation remained below average to average in the agriculturally extensive areas of Haryana, Uttar Pradesh, Bihar, eastern Nepal, and the Rajshahi district in Bangladesh in the Ganges basin and northern Bangladesh, Meghalaya, Assam, and Arunachal Pradesh in the Brahmaputra basin. This pattern implies that a regular water deficit is likely in these areas with implications for the agriculture sector due to its reliance on consistent rainfall for successful production. Major flooding and drought occurred as a consequence of the interactive effects of the ENSO and IO dipole modes, with the sole exception of extreme precipitation and flooding during El Niño events. This observational analysis will facilitate well informed decision making in minimizing natural hazard risks and climate impacts on agriculture, and supports development of strategies ensuring optimized use of water resources in best management practice under changing climate.

    Bangladesh is vulnerable to a host of short and long-term natural hazards - widespread seasonal flooding, river erosion and channel avulsions, permanent land loss from sea level rise, natural groundwater arsenic, recurrent cyclones, landslides and huge earthquakes. These hazards derive from active fluvial processes related to the growth of the delta and the tectonics at the India-Burma-Tibet plate junctions. The Ganges and Brahmaputra rivers drain 3/4 of the Himalayas and carry ~1 GT/y of sediment, 6-8% of the total world flux. In Bangladesh, these two great rivers combine with the Meghna River to form the Ganges-Brahmaputra-Meghna Delta (GBMD). The seasonality of the rivers' water and sediment discharge is a major influence causing widespread flooding during the summer monsoon. The mass of the water is so great that it causes 5-6 cm of seasonal elastic deformation of the delta discerned by our GPS data. Over the longer-term, the rivers are also dynamic. Two centuries ago, the Brahmaputra River avulsed westward up to 100 km and has since captured other rivers. The primary mouth of the Ganges has shifted 100s of km eastward from the Hooghly River over the last 400y, finally joining the Brahmaputra in the 19th century. These avulsions are influenced by the tectonics of the delta. On the east side of Bangladesh, the >16 km thick GBMD is being overridden by the Burma Arc where the attempted subduction of such a thick sediment pile has created a huge accretionary prism. The foldbelt is up to 250-km wide and its front is buried beneath the delta. The main Himalayan thrust front is geologic research in Bangladesh is that the rapid sediment accumulation preserves a detailed structural and stratigraphic archive. We have been tapping into these records using the combination of a local, low-cost drilling method, resistivity imaging and MCS seismics, while GPS, seismology and other geophysical methods are helping to unravel GBMD dynamics.

  12. Violence Against Women: What’s Law Got to Do With It? A Reflection on Gang Rape in India

    2014-10-01

    Full Text Available The brutal gang rape of a physiotherapy student in India in December 2012 drew the world’s attention to the problem of sexual violence against women in the country.  Protests and mass public reaction towards the case pressurized the government to respond to the crisis by changing the laws on sexual violence. However, these new laws have not led to a decrease in VAW. Is this the result of the failure of the rule of law? Or does it highlight the limitations of law in absence of social change? This paper addresses the need for using law as a key tool in addressing violence against women in India.  It recognizes that unless we address the structural and root causes of violence against women, our analysis will be limited. It is important to bridge the creation of new laws, with an analysis that speaks to the role of hypermasculinity, neoliberalism and culture in VAW. If unaddressed, what may result instead are quick fixes, symbolized by passing laws that act as token gestures, rather than leading to transformative action.

    Full Text Available Detection of animals during visual surveys is rarely perfect or constant, and failure to account for imperfect detectability affects the accuracy of abundance estimates. Freshwater cetaceans are among the most threatened group of mammals, and visual surveys are a commonly employed method for estimating population size despite concerns over imperfect and unquantified detectability. We used a combined visual-acoustic survey to estimate detectability of Ganges River dolphins (Platanista gangetica gangetica in four waterways of southern Bangladesh. The combined visual-acoustic survey resulted in consistently higher detectability than a single observer-team visual survey, thereby improving power to detect trends. Visual detectability was particularly low for dolphins close to meanders where these habitat features temporarily block the view of the preceding river surface. This systematic bias in detectability during visual-only surveys may lead researchers to underestimate the importance of heavily meandering river reaches. Although the benefits of acoustic surveys are increasingly recognised for marine cetaceans, they have not been widely used for monitoring abundance of freshwater cetaceans due to perceived costs and technical skill requirements. We show that acoustic surveys are in fact a relatively cost-effective approach for surveying freshwater cetaceans, once it is acknowledged that methods that do not account for imperfect detectability are of limited value for monitoring.

    Global warming is likely to exacerbate future fluvial floods in the world’s mega-delta regions due to both changing climate and rising sea levels. However, the effects of sea level rise (SLR) on fluvial floods in such regions have not been taken into account in current global assessments of future flood risk, due to the difficulties in modeling channel bifurcation and the backwater effect. We used a state-of-the-art global river routing model to demonstrate how these complexities contribute to future flood hazard associated with changing climate and SLR in the world’s largest mega-delta region, the Ganges-Brahmaputra-Meghna Delta. The model demonstrated that flood water in the main channels flows into tributaries through bifurcation channels, which resulted in an increase in inundation depth in deltaic regions. We found that there were large areas that experienced an increase in inundation depth and period not directly from the SLR itself but from the backwater effect of SLR, and the effect propagated upstream to locations far from the river mouth. Projections under future climate scenarios as well as SLR indicated that exposure to fluvial floods will increase in the last part of the 21st century, and both SLR and channel bifurcation make meaningful contributions.

    Full Text Available Groundwater levels in shallow aquifers underlying Asian mega-deltas are characterized by strong seasonal variations associated with monsoon rainfall. To resolve trend and seasonal components in weekly groundwater levels in the Ganges-Brahmaputra-Meghna (GBM Delta, we apply a nonparametric seasonal-trend decomposition procedure (STL to observations compiled from 1985–2005 in Bangladesh. Seasonality dominates observed variance in groundwater levels but declining groundwater levels (>1 m/yr are detected in urban and peri-urban areas around Dhaka as well as in north-central, northwestern, and southwestern parts of the country (0.1–0.5 m/yr where intensive abstraction of groundwater is conducted for dry-season rice cultivation. Rising groundwater levels (0.5–2.5 cm/yr are observed in the estuarine and southern coastal regions. This novel application of the STL procedure reveals, for the first time, the unsustainability of irrigation supplied by shallow aquifers in some areas (e.g., High Barind Tract of the GBM Delta and the hydrological impact of potential seawater intrusion of coastal aquifers associated with sea-level rise. Our findings provide important insight into the hydrological impacts of groundwater-fed irrigation and sea-level rise in other Asian mega-deltas where monitoring data are limited.

    We analyze previously published geodetic data and intensity values for the = 8.1 Shillong (1897), = 7.8 Kangra (1905), and = 8.2 Nepal/Bihar (1934) earthquakes to investigate the rupture zones of these earthquakes as well as the amplification of ground motions throughout the Punjab, Ganges and Brahmaputra valleys. For each earthquake we subtract the observed MSK intensities from a synthetic intensity derived from an inferred planar rupture model of the earthquake, combined with an attenuation function derived from instrumentally recorded earthquakes. The resulting residuals are contoured to identify regions of anomalous intensity caused primarily by local site effects. Observations indicative of liquefaction are treated separately from other indications of shaking severity lest they inflate inferred residual shaking estimates. Despite this precaution we find that intensites are 1–3 units higher near the major rivers, as well as at the edges of the Ganges basin. We find evidence for a post-critical Moho reflection from the 1897 and 1905 earthquakes that raises intensities 1–2 units at distances of the order of 150 km from the rupture zone, and we find that the 1905 earthquake triggered a substantial subsequent earthquake at Dehra Dun, at a distance of approximately 150 km. Four or more = 8 earthquakes are apparently overdue in the region based on seismic moment summation in the past 500 years. Results from the current study permit anticipated intensities in these future earthquakes to be refined to incorporate site effects derived from dense macroseismic data.

    The world's deltas are probably the most vulnerable type of coastal environment, and they face multiple stresses in the coming decades. These stresses include, amongst others, local drivers due to land subsidence, population growth and urbanisation within the deltas, regional drivers due to changes in catchment management (e.g. upstream land use and dam construction), as well as global climate change impacts such as sea-level rise. At the same time, the ecosystem services of river deltas support high population densities, with around 14% of the global population inhabiting deltas. A large proportion of these people experience extremes of poverty and they are therefore severely exposed to vulnerability from environmental and ecological stress and degradation. In areas close to or below the poverty boundary, both subsistence and cash elements of the economy tend to rely disproportionately heavily on ecosystem services which underpin livelihoods. Therefore, to sustainably manage delta environments they must be viewed as complex social-environmental systems where change is only partially driven by physical drivers such as sea level rise and climate change, and human-induced development activities are also critical. Here we outline a new conceptual framework for the development of methods to understand and characterise the key drivers of change in ecosystem services that affect the environment and economic status of populous deltas, focusing specifically on the Ganges-Brahmaputra-Meghna (GBM) mega-delta. The GBM delta is characterised by densely populated coastal lowlands with significant poverty, with livelihoods supported to a large extent by natural ecosystems such as the Sunderbahns (the largest mangrove forest in the world). However, the GBM delta is under severe development pressure due to many growing cities. At present the importance of ecosystems services to poverty and livelihoods is poorly understood. This is due to due to the complexity of interactions

    U-series nuclides have the potential to bring important information on the transfer time of sediments in the alluvial plains. This is a consequence of the dual property of these nuclides 1) to be fractionated during physical denudation and chemical weathering processes and 2) to have radioactive decay periods of the same order of magnitude as the time-scales of these processes (e.g. Chabaux et al., 2003b, 2008). We have illustrated such a potential with the analysis of U-series disequilibria in sediments collected in the Ganges and Bramaputra river basin. The approach relies on the analysis of U-series in river sediments collected along the streams. Indeed, as illustrated in Granet et al. (2007), in large alluvial plains where sediments are only transferred and not affected by additional inputs of new weathering products from fresh rocks, the intensity of 238U-234U-230Th disequilibria in river sediments will only depend on two parameters: (a) the duration of the transfer including the time spent in soils and in the river, and (b) the nature and the intensity of U-Th fractionations occurring in sediments during their transfer into alluvial plains. Recovering time information from the variation of U-Th disequilibria in such sediments requires therefore the use of realistic models accounting for the U-Th fractionation of sediments during their transfers into the plain. From the data, it is proposed for the Ganges and Bramaputra river sediments, that the main U-Th fractionation process is connected with the sediment weathering during their transit and storage in the plain. In this case the U-Th variation in sediments along the two main rivers lead to quite long sediment transfer time in the alluvial plains, of 100-150 ky for Bramaputra plain and of 400 or 500 ky for the Ganges river.

    Late Pleistocene to Holocene shifts of climate and vegetation in the Long Gang Volcanic Field in NE China have been reconstructed, e. g. by Steblich et al. (2009), based on Maar lake sediment cores. In this study, we investigated soil development during the Late Pleistocene and Holocene and linked it to the climate and vegetation reported in the literature. Three pedons were described and analyzed on a crater wall surrounding a maar. The lower part of the slope is covered by basic pyroclastics that are obviously younger than the maar itself. Pedon 1 is located on the upper slope, where the younger pyroclastics are not present; thus it developed over the entire Holocene and part of the Late Pleistocene. Pedon 2 is on the toe slope and developed from the young basic pyroclastics. Vegetation remains, charred by fire that was caused by the volcanic ash fall, were found in the lowermost part of the pyroclastics layer, on top of a paleosol. Charcoal fragments were dated to 18950-18830 cal BP (using INTCAL 09). Thus, pedon 2 developed since around 18.9 ka BP, whereas the development of the paleosol that was buried under the pyroclastics (pedon 3), was stopped at this time. Pedons 1 and 2 are Vitric Andosols, developed mainly from basic pyroclastics, as evidenced by the composition of rock fragments in the soils, comprising 78 / 81 mass % lapilli and 22 / 19 mass % gneiss fragments, respectively. Pedon 3 is a Cutanic Luvisol (Chromic) that developed entirely from gneiss fragments produced by the maar explosion. Lab data suggest increasing intensity of pedogenesis in the direction: Pedon 3 (paleosol) < Pedon 2 < Pedon 1, reflected e. g. in increasing Fed/Fet ratios, decreasing molar ratios of (Ca+K+Na)/Al, and decreasing pH. However, it needs to be considered that lapilli are more readily weatherable than gneiss fragments.

    In order to respond to the demands made on passenger car power train systems regarding reduction of fuel consumption, pollutant and noise emissions, increased performance and drive comfort, corporate product identification and innovative products, an 6-speed automatic transmission for standard use with 8- and 12-cylinder engines was developed. The demands of customers as well as production aspects were taken into account in the development process. Compared with its predecessor, the ZF-6HP26 provides a higher torque capacity, is more compact and 13% lighter. As a result of consistent system and component optimization, the transmission has a reduced number of components, lower transmission losses and increased efficiency. At the same time, functionality regarding reduction of fuel consumption and increase in comfort has been expanded. Fuel consumption simulation for a vehicle with 8-cylinder Otto engine revealed that fuel consumption was cut by 5 to 6% while acceleration was improved by 4%. Consumption tests with prototype transmissions confirmed the computed results. The 6HP26 is worldwide the first 6-speed automatic transmission and a milestone in passenger car transmission technology. (orig.)

    The potential impacts of climate change and socio-economic change on flow and water quality in rivers worldwide is a key area of interest. The Ganges-Brahmaputra-Meghna (GBM) is one of the largest river basins in the world serving a population of over 650 million, and is of vital concern to India and Bangladesh as it provides fresh water for people, agriculture, industry, conservation and for the delta system downstream. This paper seeks to assess future changes in flow and water quality utilising a modelling approach as a means of assessment in a very complex system. The INCA-N model has been applied to the Ganges, Brahmaputra and Meghna river systems to simulate flow and water quality along the rivers under a range of future climate conditions. Three model realisations of the Met Office Hadley Centre global and regional climate models were selected from 17 perturbed model runs to evaluate a range of potential futures in climate. In addition, the models have also been evaluated using socio-economic scenarios, comprising (1) a business as usual future, (2) a more sustainable future, and (3) a less sustainable future. Model results for the 2050s and the 2090s indicate a significant increase in monsoon flows under the future climates, with enhanced flood potential. Low flows are predicted to fall with extended drought periods, which could have impacts on water and sediment supply, irrigated agriculture and saline intrusion. In contrast, the socio-economic changes had relatively little impact on flows, except under the low flow regimes where increased irrigation could further reduce water availability. However, should large scale water transfers upstream of Bangladesh be constructed, these have the potential to reduce flows and divert water away from the delta region depending on the volume and timing of the transfers. This could have significant implications for the delta in terms of saline intrusion, water supply, agriculture and maintaining crucial ecosystems such

    Piezometric monitoring in vertical profile at sites across the southern and coastal floodplains of the Ganges/Brahmaputra/Meghna (GBM) delta confirms gravitational flow in sediments of the Bengal Aquifer System (BAS) to a depth of at least 320 m (the maximum depth of measurement). Individual and paired records of groundwater head indicate seasonal recovery and recession of water storage, periodic and episodic ground surface loading, and earth tide responses. Lunar periodicity in groundwater head fluctuation coincident with tide height at one coastal site is consistent with tidal surface loading/unloading. Diurnal tidal fluctuations in the same record change amplitude and shift phase with depth, also indicative of surface loading/unloading. Transience in the surface loading signals with depth is governed by the vertically integrated hydraulic properties of the thick BAS sedimentary sequence. Inland, earth tide responses of smaller amplitude and lacking phase shift with depth are ubiquitous in the background signal. Most records include clearly resolvable episodic deflections in the order of 0.1 m water head and up to 0.5 m water head, near simultaneous with depth, corresponding to individual episodes of rainfall. The episodic head deflections provide a record of change in terrestrial water storage (ΔTWS) comprising undifferentiated surface water flooding, soil moisture and shallow groundwater recharge - a direct land-based equivalent of satellite estimates of ΔTWS. Enigmatic short-term recession from individual deflection peaks may be related to elastic deformation and ground surface lowering under terrestrial water storage loading.

    Empathy is considered a key construct in the empirical study of high-risk adolescent and young adult delinquency, crime, and violence. This study examined the psychometric properties and criterion-related validity of a Spanish adaptation of the Basic Empathy Scale (BES), which is an important measure designed to capture both affective and cognitive empathy that has been validated in multiple languages but not in Spanish. The study's sample consisted of 208 high-risk and gang-involved adolescents and young adults in the Greater San Salvador Metropolitan Area. The original BES was reduced from its 20-item design to a more culturally appropriate 7-item design. The results of the confirmatory factor analysis and criterion-related validity analysis indicate that the adapted BES is a valid and reliable multidimensional measure of empathy for high-risk Salvadoran adolescents and young adults. Consistent with previous findings, females reported lower levels of empathy than males and delinquent/violent respondents reported lower levels of empathy than their nonoffender counterparts.

  17. River flow forecasting with Artificial Neural Networks using satellite observed precipitation pre-processed with flow length and travel time information: case study of the Ganges river basin

    2009-04-01

    Full Text Available This paper explores the use of flow length and travel time as a pre-processing step for incorporating spatial precipitation information into Artificial Neural Network (ANN models used for river flow forecasting. Spatially distributed precipitation is commonly required when modelling large basins, and it is usually incorporated in distributed physically-based hydrological modelling approaches. However, these modelling approaches are recognised to be quite complex and expensive, especially due to the data collection of multiple inputs and parameters, which vary in space and time. On the other hand, ANN models for flow forecasting are frequently developed only with precipitation and discharge as inputs, usually without taking into consideration the spatial variability of precipitation. Full inclusion of spatially distributed inputs into ANN models still leads to a complex computational process that may not give acceptable results. Therefore, here we present an analysis of the flow length and travel time as a basis for pre-processing remotely sensed (satellite rainfall data. This pre-processed rainfall is used together with local stream flow measurements of previous days as input to ANN models. The case study for this modelling approach is the Ganges river basin. A comparative analysis of multiple ANN models with different hydrological pre-processing is presented. The ANN showed its ability to forecast discharges 3-days ahead with an acceptable accuracy. Within this forecast horizon, the influence of the pre-processed rainfall is marginal, because of dominant influence of strongly auto-correlated discharge inputs. For forecast horizons of 7 to 10 days, the influence of the pre-processed rainfall is noticeable, although the overall model performance deteriorates. The incorporation of remote sensing data of spatially distributed precipitation information as pre-processing step showed to be a promising alternative for the setting-up of ANN models for

    A semi-distributed flow and water quality model (INCA- Integrated Catchments Model) has been set up for the whole of the Ganges- Brahmaputra- Meghna (GBM) River system in India and Bangladesh. These massive rivers transport large fluxes of water and nutrients into the Bay of Bengal via the GBM Delta system in Bangladesh. Future climate change will impact these fluxes with changing rainfall, temperature, evapotranspiration and soil moisture deficits being altered in the catchment systems. In this study the INCA model has been used to assess potential impacts of climate change using the UK Met Office Hadley Centre GCM model linked to a regionally coupled model of South East Asia, covering India and Bangladesh. The Hadley Centre model has been pururbed by varying the parameters in the model to generate 17 realisations of future climates. Some of these reflect expected change but others capture the more extreme potential behaviour of future climate conditions. The 17 realisations have been used to drive the INCA Flow and Nitrogen model inorder to generate downstream times series of hydrology and nitrate- nitrogen. The variability of the climates on these fluxes are investigated and and their likley impact on the Bay of Begal Delta considered. Results indicate a slight shift in the monsoon season with increased wet season flows and increased temperatures which alter nutrient fluxes. Societal Importance to Stakeholders The GBM Delta supports one of the most densely populated regions of people living in poverty, who rely on ecosystem services provided by the Delta for survival. These ecosystem services are dependent upon fluxes of water and nutrients. Freshwater for urban, agriculture, and aquaculture requirements are essential to livelihoods. Nutrient loads stimulate estuarine ecosystems, supporting fishing stocks, which contribute significantly the economy of Bangladesh. Thus the societal importance of upstream climate driven change change in Bangladesh are very

    2013-12-01

    The densely populated low lying Ganges-Brahmaputra Delta is highly vulnerable to the global sea-level rise. In order to estimate the subsidence of the delta over historical time scales, we examined submerged salt-producing kiln sites in the coastal Sundarbans. These kilns were built just above the previous winterly spring high-tide level, but are currently located ~155 × 15 cm below the corresponding modern level. According to optically stimulated luminescence (OSL) dating, the kilns were ultimately fired ~300 years ago (1705 × 35 AD) and salt production was terminated abruptly by a catastrophic event (major cyclone), which affected the kiln sites at different levels and locations. Two particular buried mangrove root horizons 80 cm below this kiln level also indicate catastrophic scenarios (probably subsidence events related to a regional earthquake). AMS-14C ages measured on the charcoal layers at the kiln's bases and on these associated mangrove stump horizons support the OSL dates. Based on the respective elevations of these kiln and mangrove palaeo-horizons and on the ages, the 300-year-average rate of sinking of the outer delta is 5.2 × 1.2 mm/a, which includes 0.8 mm/a of eustatic sea-level rise over this historical period. Expecting further acceleration of the eustatic sea-level rise of up to 7 mm/a, we calculate a rise in relative sea level of up to 8.9 × 3.3 mm/a for the next few decased, which will dramatically aggravate the already present problematic situation. Only a prudently-managed control of sediment accretion will keep southern Bangladesh above the sea level. (Hanebuth et al., Geology, Sept 2013, doi: 10.1130/G34646.1.)

    The Ganges-Brahmaputra Delta hosts a dense network of tidal channels extending inland as far as 100 kilometers from the coast. With semidiurnal tides up to 6.7 meters in amplitude, this setting is ideal for testing hypotheses related to tidal meander morphology, intertidal sediment transport, and channel-platform linkages. We present results from two field surveys in March and September 2015, corresponding to the dry and monsoon seasons, respectively. Comparing acoustic Doppler current profiler (ADCP) data and pressure sensor measurements from the Sibsa River in southwest Bangladesh reveals a phase lag of as much as 1 hour between maximum discharge and mean water level. Variations in this phase lag at different points along the channel allow us to test an existing conceptual model of cuspate tidal meander formation. To address a related but separate question, we observe that the ratio of cumulative discharges Qin/Qout is approximately equal during both spring and neap tides at a strategically-placed ADCP transect south of the study area. In contrast, ADCP data obtained north of the study area shows that Qin/Qout=1.4 during spring tides and 0.85 during neap tides. We examine the degree to which this phenomenon is controlled by the establishment of a hydraulic gradient between the Sibsa and a parallel tidal channel, the Pussur, versus the exchange of water between the channel and the tidal flats during the ebb-flood cycle. These results have implications for identifying loci of sediment erosion and deposition within the network.

    River modeling is the processing of setting up a physically-based hydrodynamic model that can simulate the water flow dynamics of a stream network against time varying boundary conditions. Such river models are an important component of any flood forecasting system that forecasts river levels in flood prone regions. However, many large river basins in the developing world such as the Ganges, Brahmaputra, Meghna (GBM), Indus, Irrawaddy, Salween, Mekong and Niger are mostly ungauged. Such large basins lack the necessary in-situ measurements of river bed depth/slope, bathymetry (river cross section), floodplain mapping and boundary condition flows for forcing a river model. For such basins, proxy approaches relying mostly on remote sensing data from space platforms are the only alternative. In this study, we share our experience of setting up the widely-used 1-D river model over the entire GBM basin and its stream network. Good quality in-situ measurements of river hydraulics (cross section, slope, flow) was available only for the downstream and flood prone region of the basin, which comprises only 7% of the basin area. For the remaining 93% of the basin area, we resorted to the use of data from the following satellite sensors to build a workable river model: a) Shuttle Radar Topography Mission (SRTM) for deriving bed slope; b) LANDSAT/MODIS for updating river network and flow direction generated by elevation data; c) radar altimetry data to build depth versus width relationship at river locations; d) satellite precipitation based hydrologic modeling of lateral flows into main stem rivers. In addition, we referred to an extensive body of literature to estimate the prevailing baseline hydraulics of rivers in the ungauged region. We measured success of our approach by systematically testing how well the basin-wide river model could simulate river level dynamics at two measured locations inside Bangladesh. Our experience of river modeling was replete with numerous

    Deltas can subside very fast, yet many deltas remain emergent over geologic time. A large sediment input is often enough to compensate for subsidence and rising sea level to keep many deltas at sea level. This implies a balance between subsidence and sedimentation, both of which may, however, be controlled by independent factors such as sediment supply, tectonic loads and sea-level change. We here examine the subsidence of the Ganges-Brahmaputra Delta (GBD). Located in the NE boundary of the Indian-Eurasian collision zone, the GBD is surrounded by active uplifts (Indo-Burma Fold Belt and the Shillong Massif). The pattern of subsidence from these tectonic loads can strongly vary depending on both loads and lithospheric flexural rigidity, both of which can vary in space and time. Sediment cover changes both the lithostatic pressure and the thermal properties and thus the rigidity of the lithosphere. While sediments are deposited cold, they also insulate the lithosphere, acting as a thermal blanket to increase lower crustal temperatures. These effects are a function of sedimentation rates and may be more important where the lithosphere is thin. At the massive GBD the impact of sedimentation should be considered for properly constraining flexural subsidence. The flexural rigidity of the lithosphere is here modeled by using a yield-stress envelope based on a thermomechanic model that includes geothermal changes associated with sedimentation. Models are constrained by using two different data sets, multichannel seismic data correlated to borehole stratigraphy, and gravity data. This approach allows us to determine the Holocene regional distribution of subsidence from the Hinge Zone to the Bengal Fan and the mass-anomalies associated with the flexural loading. Different end-member scenarios are explored for reproducing the observed land tilting and gravity anomalies. For all scenarios considered, data can be reproduced only if we consider an extremely weak lithosphere and

    As part of an NSF PIRE grant, we have led four field trips for undergraduate, MS and PhD students to large deltaic systems. Three trips took US students to the Ganges-Brahmaputra (GB) delta in Bangladesh and one brought Bangladeshi faculty and students to the Mississippi (Miss.) delta in the US. An essential component in the learning process and overall experience of each trip was that ~2/5 of the participants were students and professors from Bangladesh. In all cases, the involvement of a substantial international cohort greatly broadened perspectives on the topics being covered. For example, in GBD the local geologic and cultural knowledge of the Bangladeshis deepened the learning and engagement of the US students, an outcome that was almost universally noted in student reviews. The trips received similar feedback from Bangladeshi participants, as they had an enthusiastic and engaged audience of peers from the US. Even for the Miss. delta trip, the Bangladeshis added a unique perspective from a nation that faces similar environmental issues. These overwhelmingly positive contributions have been experienced in several different contexts. Three trips were associated with US courses and run over Spring Break. One matched sustainable development undergrads at Columbia U. with geology undergrads from Dhaka U., and two others matched a mixed group of graduate and undergrad students from Vanderbilt U. with cohorts from Bangladesh. The fourth trip was a stand-alone Field School for PhD students from 14 US universities and mostly MS students from 4 Bangladeshi universities. The focus of each trip ranged from broader surveys of tectonic, fluvial and coastal processes to investigations of geology and people affected by tropical storms. Of particular interest was the success of mixing undergrad and graduate students in the Vanderbilt course, which centered on the intersection of social sciences, physical sciences, and engineering. In this case, undergrads engaged in a

    Coastal flooding due to storm surge and high tides is a serious risk for inhabitants of the Ganges-Brahmaputra-Meghna (GBM) delta, as much of the land is close to sea level. Climate change could lead to large areas of land being subject to increased flooding, salinization and ultimate abandonment in West Bengal, India, and Bangladesh. IPCC 5th assessment modelling of sea level rise and estimates of subsidence rates from the EU IMPACT2C project suggest that sea level in the GBM delta region may rise by 0.63 to 0.88 m by 2090, with some studies suggesting this could be up to 0.5 m higher if potential substantial melting of the West Antarctic ice sheet is included. These sea level rise scenarios lead to increased frequency of high water coastal events. Any effect of climate change on the frequency and severity of storms can also have an effect on extreme sea levels. A shelf-sea model of the Bay of Bengal has been used to investigate how the combined effect of sea level rise and changes in other environmental conditions under climate change may alter the frequency of extreme sea level events for the period 1971 to 2099. The model was forced using atmospheric and oceanic boundary conditions derived from climate model projections and the future scenario increase in sea level was applied at its ocean boundary. The model results show an increased likelihood of extreme sea level events through the 21st century, with the frequency of events increasing greatly in the second half of the century: water levels that occurred at decadal time intervals under present-day model conditions occurred in most years by the middle of the 21st century and 3-15 times per year by 2100. The heights of the most extreme events tend to increase more in the first half of the century than the second. The modelled scenarios provide a case study of how sea level rise and other effects of climate change may combine to produce a greatly increased threat to life and property in the GBM delta by the end

    Effective risk analysis and the management of complex coastal systems require that the scale of interest be well defined. Here we present recent research from the Ganges-Brahmaputra river delta (GBD) that highlights different, if not divergent, perspectives on the current status of this system and its potential response to future environmental change. The contrasts emerge from viewing the GBD at different temporal and spatial scales, raising the question of how scientists, stakeholders, and decision makers might most effectively develop a shared understanding of large, at-risk delta systems. Among the world's deltas, the GBD is often cited as being highly vulnerable to future sea-level rise and environmental change, owing to its vast low-lying landscape and large human population. Taking a broad perspective, however, it is not coincident that the GBD, the world's largest delta system, is fed by immense water and sediment discharge from the Asian monsoon and Himalayan orogen - simply, the size of the GBD reflects the robust processes that have constructed and maintained it. At the regional scale, the deltaplain itself is interconnected by a labyrinth of fluvial and tidal channels that effectively convey sediment to most areas of the landscape, through overbank flooding, distributaries, and tidal transport. Together, the sediment supply, water discharge, and dense channel network bless the GBD with potential basinwide accretion rates >5 mm/yr. More locally, modern sedimentation rates >10 mm/yr are observed in many areas of the tidal delta plain, which are sufficient to maintain land-surface elevations under a variety of sea-level rise scenarios, or at least to mitigate whatever effects do occur. The long-term stratigraphic record of the GBD also reflects a system in dynamic equilibrium, with major landforms persisting through changes in sea level, sediment loading, river avulsion, and delta lobe switching - together providing an encouraging outlook in the face of

    Full Text Available Ottoman Empire has considerably struggled with the matter of minorities in the political area since the second half of the 19th century. Moreover, this matter has continued until Treaty of Lausanne. An artificial problem of Pontus was created in Ottoman Empire by influences of especially French Revolution and the great powers that had aspirations on Ottoman Empire. However, there is no relationship between the Pontus State in the history and the Pontus State which is put forth and desired to be carried out. In the 19th century, Ottoman Empire, which was multilateral, multi-religious and multicultural, had entered the duration of disintegration because of the effect of both internal and external forces due to the property of the age. While the minorities in the Ottoman Empire were gradually splitting from it by the supports of the big nations, the Greeks lived together with the Turks in the Anatolia for centuries started to imagine establishing a Pontus State ranging from the west of İnebolu to Batum. They chose Samsun as the capital city of the state. Therefore, they started to gang activities in and around Samsun. The religious men have active roles in provoking these gangs. Against all of these, by taking various precautions, Ottoman Empire tried to stop these destructive and cruel activities against the Muslim community Osmanlı Devleti, XIX. yüzyılın ikinci yarısından itibaren siyasî alanda azınlıklar meselesiyle oldukça meşgul olmuştur. Hatta bu konu Lozan Antlaşmasına kadar devam etmiştir. Bilhassa Fransız İhtilali’nin ve Osmanlı Devleti üzerinde emelleri olan büyük güçlerin etkisiyle Osmanlı içerisinde yapay bir Pontus meselesi ortaya çıkartılmıştır. Oysaki tarihteki Pontus Devleti ile ortaya atılan ve gerçekleştirilmek istenen Pontus Devleti arasında hiçbir bağlantı yoktur.

    Full Text Available While violence directed at Indian students in Australian cities has been highlighted in the Indian and Australian press, far less attention has been paid to the violence directed at Indians in rural areas. This has most often involved Indians employed in contract labour in seasonal industries like fruit or vegetable picking. This article reviews various media accounts, both urban and rural, of violence directed at Indians from 2009 to 2012. It draws attention to the far longer history of labour exploitation which has taken place in rural and urban Australia in contract labour conditions and the particular invisibility of rural settings for such violence. Racial minorities, like Aboriginal and Chinese workers, and women in agriculture and domestic work, have seldom had adequate power to respond industrially or politically. This means that in the past, these groups been particularly vulnerable to such structural exploitation. The paper concludes by calling for greater attention not only to the particular vulnerability of Indians in rural settings but to the wider presence of racialised and gendered exploitation enabled by contract labour structures.

This paper shows that SSS can enhance water supply, and provide benefits for irrigation and other water use sectors. In addition, it can buffer the inherent variability in water supply and mitigate extreme flooding, especially in the downstream parts of the basin. It can also increase river flow during low-flow months via baseflow or enable the re-allocation of irrigation canal water. Importantly, SSS can mitigate the negative effects of both flooding and water scarcity in the same year, which often affects the most vulnerable segments of society – women and children, the poor and other disadvantaged social groups.

  20. Social adaptation of Latin American youth gangs in Spain: Gangs and street youth organisations

    Directory of Open Access Journals (Sweden)

    Juan Pablo Soriano Gatica

    2008-04-01

    Full Text Available This article carries out a brief summary of the evolution of the phenomenon of what are known as “Latino gangs” in Spain since the late 1990s. The upsurge of these new street youth organisations is closely linked with the mass arrival of thousands of young Latin Americans in Spain during the past decade, and the consequent integration challenges that this has brought for both the welcoming society and for the young newcomers. In the sphere of public policy inSpain, there have been two main approaches to the phenomenon: one which is more oriented towards repression than prevention, and the other, known as the “Barcelona model”, which has promoted a process of normalisation and integration of these groups into Spanish society. The second option makes it possible for different social actors to carry out coordinated actions, and may serve as a guideline for developing similar initiatives in different countries in Europe and Latin America.

    Objective To investigate the change laws of blood pressure-temperature ganged fluctuation and TCM four examination information in the patients with acute cerebral infarction (ACI), and find out its syndrome characteristics. Methods The information of body temperature, blood pressure, TCM four examinations and NIHSS scores were collected dynamically from the patients. The correlation among the data was analysed, logistic regression equation and principal component analysis (PCP) were set up, and the score values of them were compared dynamically. The scores of comprehensive evaluation were counted. Results There was a correlation between blood pressure-temperature ganged fluctuation (increase of temperature and sudden changes of blood pressure) and NIHSS scores. The information of TCM four examinations in a group of symptoms (coma, dysphasia or aphasia and mucopurulent eye secretion) were closely related to the blood pressure-temperature ganged fluctuation. The results of PCP showed that the proportion of all principal components as follows: pricipal component 1 (coma,polypnea, bad breath, swift pulse and dull complexion) accounted for 34.655%, principal component 2 (aphasia, mucopurulent eye secretion and yellow sputum), 16.575%, and total proportion of component 1 and 2, 51.23%. The scores of comprehensive evaluation were counted according to the equation of (principal component 1 × 34.655% + principal component 2 × 16.575 ) ÷ 51.23%, and the result showed that the scores of comprehensive evaluation of principal components changed from negative value to positive value. The information of TCM four examinations changed most radically on the 3rd to 5th day of ACI with different endpoints. The changes of the information of TCM four examinations were different with sensitivity and specificity in this group of symptoms. Conclusion The information of TCM four examinations collected dynamically reflects the characteristics of fire-toxin syndrome of brain

    2008-04-01

    Full Text Available This work presents an approach of what have become known as “Latino gangs”, and has been carried out in Barcelona since this reality first came to light, in late 2002. The approach is based onone of the criteria that Barcelona City Council has defined as a basic element of its urban policy, that is, to develop interventions that facilitate the integration of new emerging urban realities, even those that may result in the generation of conflict in the city’s social and political life. Meanwhile, one sine qua non condition is the acceptance of the rule of common law, and of the very diversityof the city’s community life. In the case under study, the aim has been to encourage groups of young Latinos who have been “branded” as dangerous to commence processes of normalisation, by exploring the associational route as a democratic resource for functioning socially.

    This study presents an easy, modular, user-friendly, and flexible software package for processing of Landsat 7 ETM and Landsat 8 OLI-TIRS data for estimating suspended particulate matter concentrations in the coastal waters. This package includes 1) algorithm developed using freely downloadable SCILAB package, 2) ERDAS Models for iterative processing of Landsat images and 3) ArcMAP tool for plotting and map making. Utilizing SCILAB package, a module is written for geometric corrections, radiometric corrections and obtaining normalized water-leaving reflectance by incorporating Landsat 8 OLI-TIRS and Landsat 7 ETM+ data. Using ERDAS models, a sequence of modules are developed for iterative processing of Landsat images and estimating suspended particulate matter concentrations. Processed images are used for preparing suspended sediment concentration maps. The applicability of this software package is demonstrated by estimating and plotting seasonal suspended sediment concentration maps off the Bengal delta. The software is flexible enough to accommodate other remotely sensed data like Ocean Color monitor (OCM) data, Indian Remote Sensing data (IRS), MODIS data etc. by replacing a few parameters in the algorithm, for estimating suspended sediment concentration in coastal waters.

    Although the front-fanged venom delivery system of the Elapidae is believed to be derived from an aglyphous or opisthoglyphous colubroid ancestor, opinion is divided as to the end of the maxilla on which the proteroglyph fang originated. This study was undertaken to determine whether the evolutionary precursor of the proteroglyph fang was (a) a grooved posterior fang which migrated anteriorly, or (b) an enlarged anterior tooth which secondarily developed a groove for the conduction of venom. The surface morphology of the maxillary teeth of colubrid genera was examined using scanning electron microscopy. Ridges present on the lingual and labial surfaces of anterior maxillary teeth and on the anterior and posterior surfaces of posterior maxillary teeth were identified as morphological markers of potential value in distinguishing the anterior and posterior maxillary teeth of colubrid snakes, and in determining the origin of the proteroglyph fang. Patterns of ridges on the surfaces of elapid fangs examined were found to be consistent with the hypothesis that the evolutionary precursor of the proteroglyph fang was an opisthoglyph fang which migrated anteriorly.

  14. Pathogenic functions of B cells in autoimmune diseases: IFN-γ production joins the criminal gang.

    2015-04-01

    B-cell depletion therapy has emerged as a powerful strategy to intercept the progression of T-cell-mediated autoimmune diseases such as rheumatoid arthritis, type 1 diabetes, or relapsing remitting multiple sclerosis. However, its mode of action remains incompletely defined, reflecting our incomplete understanding of the pathogenic functions of B cells in such pathologies. B cells can contribute to immune responses through the production of antibodies, presentation of antigen to T cells, and production of cytokines. In this issue of the European Journal of Immunology [Eur. J. Immunol. 2015. 45: 988-998], Olalekan et al. demonstrate that IFN-γ production by B cells is essential for the development of arthritis in mice. Lack of IFN-γ expression in B cells results in reduced autoimmune T-cell responses and autoantibody levels, impacting the arthritogenic reaction akin to that in B-cell depletion therapy. Together with other reports, the article by Olalekan et al. emphasizes the importance of cytokine-producing B cells in the pathogenesis of autoimmune diseases. In this commentary, I discuss how these findings shed new light on the roles of B cells as drivers of autoimmune pathogenesis, and how they more generally contribute to our understanding of the role of B cells in immunity.

  1. A review of arsenic and its impacts in groundwater of the Ganges-Brahmaputra-Meghna delta, Bangladesh.

    Science.gov (United States)

    Edmunds, W M; Ahmed, K M; Whitehead, P G

    2015-06-01

    Arsenic in drinking water is the single most important environmental issue facing Bangladesh; between 35 and 77 million of its 156 million inhabitants are considered to be at risk from drinking As-contaminated water. This dominates the list of stress factors affecting health, livelihoods and the ecosystem of the delta region. There is a vast literature on the subject so this review provides a filter of the more important information available on the topic. The arsenic problem arises from the move in the 1980s and 1990s by international agencies to construct tube wells as a source of water free of pathogens, groundwater usually considered a safe source. Since arsenic was not measured during routine chemical analysis and also is difficult to measure at low concentrations it was not until the late 1990s that the widespread natural anomaly of high arsenic was discovered and confirmed. The problem was exacerbated by the fact that the medical evidence of arsenicosis only appears slowly. The problem arises in delta regions because of the young age of the sediments deposited by the GBM river system. The sediments contain minerals such as biotite which undergo slow "diagenetic" reactions as the sediments become compacted, and which, under the reducing conditions of the groundwater, release in the form of toxic As(3+). The problem is restricted to sediments of Holocene age and groundwater of a certain depth (mainly 30-150 m), coinciding with the optimum well depth. The problem is most serious in a belt across southern Bangladesh, but within 50 m of the coast the problem is only minor because of use of deep groundwater; salinity in shallow groundwater here is the main issue for drinking water. The Government of Bangladesh adopted a National Arsenic Policy and Mitigation Action Plan in 2004 for providing arsenic safe water to all the exposed population, to provide medical care for those who have visible symptoms of arsenicosis. There is as yet no national monitoring program in place. Various mitigation strategies have been tested, but generally the numerous small scale technological remedies have proved unworkable at village level. The current statistics show that use of deep groundwater (below 150 m) is the main source of arsenic mitigation over most of the arsenic affected areas as well as rainwater harvesting in certain location.

    Over the last several decades, much of population of Bangladesh and West Bengal switched their water supply from surface water to groundwater. Tragically, much of the region's groundwater is dangerously contaminated by arsenic, and consumption of this water has already created severe health effects. Here we consider how groundwater flow may affect arsenic biogeochemistry and we compare the vertical patterns of groundwater chemistry at our intensive study site with the average values across the country. Detailed hydraulic data are presented from our field site that begins to characterize the groundwater flow system. To cite this article: C.F. Harvey et al., C. R. Geoscience 337 (2005).

    2007-01-01

    Detailed rock magnetic investigations were carried out on two 23-m-long sediment cores from Erlongwan maar lake, NE China. The completely laminated sediment sequence of the lake is interrupted by 410 graded layers with thicknesses between 0.1 and 150 cm. Magnetite of PSD-size was identified as the main magnetic carrier mineral by temperature-dependent measurements of the saturation magnetization and determination of hysteresis parameters. The minerogenic components in the laminated sediments and the graded layers are nearly identical, and their rock magnetic characteristics reflect the prevailing conditions, anoxic or oxic, during deposition. The most reliable criteria for estimating the availability of oxygen is whether an increase in minerogenic influx is linked to a shift in the magnetic grain size spectrum to coarser (oxic) or finer (anoxic) grains. Comparison of different rock magnetic parameters indicative for magnetic grain size and coercitivity revealed, that the S-ratio which is known to reflect the presence of high coercive minerals, is grain size indicative in sediments with a monomineralic magnetic composition.

Such relationships have been evolving since the end of the last century as a result of the increasing expansion of the tequila agro-industry. It is of particular interest to address issues that deal with labor and social relations in the environments migrants arrive, because these relationships are based on a negative appreciation of the difference. This attitude leads the native people of Jalisco to discriminate, segregate, marginalize and exploit, not only strangers or foreigners (even in the same country, but also who, by his indigenous status, is positioned in a lower stratum and whose phenotype is far from the idealized Altos del Jalisco native: the Caucasian type, Catholic, rancher.

Even if the geographical distances were long, there are clear signs of connections between inhabitants of northern Norway and the Roman world during the Roman era. In order to understand these connections scholars also need to study Roman history in its own right. To make this point the article investigates the possible Roman connections of a well-known warrior grave from Steigen (Nordland County, North Norway, dated to the middle of the third century CE. The investigation yields no stunning new discoveries, but aims to contribute to a broader and more well-founded understanding of the buried man and the experiences he might have had, as well as a cautious and informed view of broader connections between the North and the Roman world.

    The 1950s-- and perhaps also the 1960s-- were very special times for the development of solid-state/condensed-matter physics. The University of Illinois at Urbana was at the center of these activities. In areas like NMR and superconductivity, methods were developed which would form the basis for the next half century of science and technology. Experimentalists, including Charlie and John Wheatley, worked hand in hand with theorists, including the incomparable John Bardeen. They worked cooperatively to develop ideas, often born in Urbana, but with godparents at Harvard and Moscow and Paris. A characteristic style of broad collaboration and spirited exchange developed and spread from Illinois. This development was not an accident but the result of the vision of leaders like Wheeler Loomis, Fred Seitz, and later Gerald Almy1. The strong leadership saved the other scientists from expending their time on departmental decision-making. The style of the scientific activity was set by Fred, who strongly encouraged joi...

    Policy-making in social-ecological systems increasingly looks to iterative, evolutionary approaches that can address the inherent complexity of interactions between human wellbeing, agricultural and aquacultural production, and ecosystem services. Here we show how an analysis of available time-series in delta regions over past decades can provide important insight into the social-ecological system dynamics that result from the complexity. The presentation summarises the recent changes for major elements of each social-ecological system, for example demography, economy, health, climate, food, and water. Time-series data from official statistics, monitoring programmes and sequential satellite imagery are analysed to define the range of trends, the presence of change points, slow and fast variables, and the significant drivers of change. For example, in the Bangladesh delta zone, increasing gross domestic product and per capita income levels since the 1980s mirror rising levels of food and inland fish production. In contrast, non-food ecosystem services such as water availability, water quality and land stability have deteriorated. As a result, poverty alleviation is associated with environmental degradation. Trends in indicators of human wellbeing and ecosystem services point to widespread non-stationary dynamics governed by slowly changing variables with increased probability of systemic threshold changes/tipping points in the near future. We conclude by examining how the findings could feed into new management tools, such as system dynamic models and assessments of safe operating spaces. Such tools have the potential to help create policies that deliver alternative and sustainable paths for land management while accommodating social and environmental change.

However facing the today’s gigantic surpluses of grains, and the worrisome budget deficit of the central government and the Indian states, India ha come under pressure from various national and international institutions to shift state support from grain production to other productions. For the indo-gangetic plains, current grain basket of India, dairy is considered among the best alternatives. Grain producers of these regions are already the one contributing most, with producers form the North West (Gujarat, Maharastra, to the national dairy production and they are the ones with the better chances to respond to the increasing national demand for dairy products. The simulations developed in this study show that there is an important potential for crop livestock integration and that this integration can maintain agricultural incomes; partially compensate the likely reduction of subsidies and contribute to a better management of soil fertility. Whether national production will be able to respond to the demand in grain from both humans and animals, is a hot debate in India. On one hand, dairy production system is so extensive that production can be increased easily without much additional feeding of grain or concentrates but with cheaper sources of forages. On the other hand, the rapidly increasing poultry industry depends heavily upon maize, which is still a marginal production in India.

    Rutherford and Bohr discovered the nuclear atom 100 years ago. Roughly 50 years ago a theory of this basic structure of matter was inspired by the work of Peter Higgs and others. In July 2012 the discovery "beyond reasonable doubt" of Higgs's boson, and the experimental proof of the theory, was announced and speculations about Nobel prizes mushroomed. The Economist said of Frank Close's book, The Infinity Puzzle (OUP,2012): "The Nobel Committee would be well advised to read Mr Close’s book before making their decision." This pedagogic talk reviews the ideas and the history, and assesses how the credits should be shared. The conclusions may not be what you anticipate

  7. Distribution and Mobilization of Arsenic in the Ganges plain sedimentary deposits of South-western Bangladesh; implications from field and laboratory observations

    Science.gov (United States)

    Rahman, M.; Mano, A.; Udo, K.; Ishibashi, Y.; Han, Y.

    2011-12-01

    The variation of arsenic concentration depending on sediment size and its depositional age in a variety of sediments extracted from four As contaminated sites of the southwestern Bangladesh were studied to elucidate the aquifer geological parameters that controls the vertical As distribution and mobilization in the sediment-water interface. It was found that sediment size, reactive surface area, relative depositional age and presence of other carrier minerals having higher affinity to adsorb As, may greatly dominate the arsenic accumulation. Sorption of As onto sediment surfaces was found to vary based on the variation of the particle diameters (2 to 250 μm), which eventually reflects the role of geological materials in controlling the As distribution in various depositional layers. Medium sands commonly found in the deeper aquifer (~150m), being older in age (> 7000 yrs BP) and having relatively larger diameter (φ~250 μm) were found to contain relatively low amount of As (0.8 μg/g) whereas higher As (5 to 25 μg/g) was identified noticeably in the recently deposited and reasonably younger (100 to 1000 yrs BP) sediment particles including clay and finer sands that commonly have moderately smaller diameter (φ~2 to 90 μm). These observations were supported strongly by the findings obtained from the laboratory batch adsorption tests conducted with those sediments. Presence of As was also observed to be greatly dependent on the availability of its carrier minerals particularly Fe and Al oxide/hydroxide along the aquifer depths. Clay particles with relatively moderate Fe and Al oxide minerals was found to adsorb as much as 70 μg/g As whereas medium sand with less Fe and Al oxide minerals were noticed to capture only 4 μg/g of As in the batch adsorption test. In laboratory leaching test, significant amount of As (12 μg/g) coupled with Fe (4.8 mg/g) were found to be leached out from the shallower brown clay by using sodium bicarbonate (pH~9) as the leaching agent. This implies that bicarbonate may play a key role in triggering the desorption of As in the upper shallower aquifers that explains the high As pollution there, whereas insignificant As that was desorbed from the deeper medium sand suggests that the As mobilization is not an usual phenomena in the later one.

    This paper draws upon international research evidence that suggests a relationship between protest masculinity and the manifestation of violent crime among young males, and that criminal desistance may be linked to (inter-) subjective processes such as the reconstruction of masculine identity...... an ethnographic study conducted in a boxing rehabilitation centre on the outskirts of Copenhagen, Denmark, the paper reports on data gleaned from participant observation and qualitative interviews with 22 ethnic minority young men. Findings suggest that the masculine context within the rehabilitation programme...... provided the young men with a safe space to perform broader versions of locally dominated views on masculinity and to reflect on their current situations and dilemmas.

    Mian, M A K; Hossain, J

    2014-07-01

    A field experiment was conducted at the Regional Agricultural Research Station of Bangladesh Agricultural Research Institute, Jessore during early kharif season of 2009 and 2010 to observe the effect of nitrogen on the physiological basis of yield of mungbean at varying plant population. In the experiment, four nitrogen levels (N0, N40, N60 and N80 kg ha(-1)) were assigned in the main plots and three plant population (P30, P35 and P40 m(-2)) in the sub plots. The results revealed that mungbean showed better growth in N60 and N80 kg ha(-1) representing higher values of CGR, TDM, LAI and plant height while N40 exhibited intermediate growth. Again, growth of mungbean was better in higher plant population (35-40 m(-2)) representing higher values of growth parameters. Seed yield of mungbean was obtained the highest (1908 kg ha(-1)) associated with the highest No. of pods plant(-1) (29.98), seeds pod(-1) (10.41) and 1000-seed weight (37.70 g) in N40 kg ha(-1). Further, seed yield of mungbean was the highest (1919 kg ha(-1)) in plant population of 40 m(-2). In interaction, seed yield was the highest (1963 kg ha(-1)) in N40 kg ha(-1) with plant population of 40 m(-2). The effect of applied nitrogen on the seed yield of mungbean can be explained 78% (R2 = 0.78) by this function (Y = 1540.70+16.069x-0.173x2). The optimum nitrogen level was 46 kg ha(-1) by using the developed functional model and then the predicted seed yield of mungbean would be 1944 kg ha(-1).

    Science.gov (United States)

    Cooley, Will

    2011-01-01

    In the 1960s and 1970s African American “supergangs” emerged in Chicago. Many scholars have touted the “prosocial” goals of these gangs but fail to contextualize them in the larger history of black organized crime. Thus, they have overlooked how gang members sought to reclaim the underground economy in their neighborhoods. Yet even as gangs drove out white organized crime figures, they often lacked the know-how to reorganize the complex informal economy. Inexperienced gang members turned to extreme violence, excessive recruitment programs, and unforgiving extortion schemes to take power over criminal activities. These methods alienated black citizens and exacerbated tensions with law enforcement. In addition, the political shelter enjoyed by the previous generation of black criminals was turned into pervasive pressure to break up street gangs. Black street gangs fulfilled their narrow goal of community control of vice. Their interactions with their neighbors, however, remained contentious.

  17. Determining the background levels of bismuth in tissues of wild game birds: a first step in addressing the environmental consequences of using bismuth shotshells.

    Jayasinghe, R; Tsuji, L J S; Gough, W A; Karagatzides, J D; Perera, D; Nieboer, E

    2004-11-01

    Bismuth shotshells have been approved as a "nontoxic" alternative to lead in North America. Approval was based on a limited number of studies; even background levels of bismuth in wildfowl were unknown. We report on the concentration of bismuth (and lead) in muscle and liver tissues of wildfowl (Anas platyrhynchos, Anas acuta, Anas crecca, Branta canadensis, Chen caerulescens) harvested with lead shotshell. Average liver-bismuth levels detected in the present study (e.g., teal, 0.05 microg/g dw; mallard, 0.09 microg/g dw) suggest analytical error in other studies examining the effects of bismuth in birds. Significant positive relationships between bismuth- and lead-tissue levels for muscle when all species were combined (and for B. canadensis and C. caerulescens separately) can be explained by noting that bismuth is a contaminant of lead. Thus, more research is recommended to confirm the appropriateness of bismuth as a "nontoxic" shot alternative.

  18. Lesser snow geese and ross's geese form mixed flocks during winter but differ in family maintenance and social status

    Jonsson, J.E.; Afton, A.D.

    2008-01-01

    Smaller species are less likely to maintain families (or other forms of social groups) than larger species and are more likely to be displaced in competition with larger species. We observed mixed-species flocks of geese in southwest Louisiana and compared frequencies of social groups and success in social encounters of Lesser Snow Geese (Chen caerulescens caerulescens; hereafter Snow Geese) with that of the smaller, closely- related Ross's Geese (C. rossii). Less than 7% of adult and social encounters and had higher odds of success against Ross's Geese than against individuals of their own species. The larger Snow Geese maintain families longer than Ross's Geese, which probably contributes to their dominance over Ross's Geese during winter. Predator vigilance probably is an important benefit of mixed flocking for both species. We suggest the long-standing association with Snow Geese (along with associated subordinate social status) has selected against family maintenance in Ross's Geese.

    1993-01-01

    The coastal plain of the Arctic National Wildlife Refuge (ANWR) is used by lesser snow geese (Chen caerulescens caerulescens) in autumn for premigratory staging. To better understand the potential impacts of human disturbance on snow geese, we investigated species composition of, and temporal and age-related variation in, their diet during staging. Depending on age and time of collection, between 35.2 and 94.1% of the diet (aggregate percent wet mass, n = 75) consisted of 2 species of plants; underground stems of tall cotton-grass (Eriophorum angustifolium), and aerial shoots of northern scouring rush (Equisetum variegatum). The diet varied between August and September (P = 0.0089), morning and afternoon (P freezing, interspecific differences in nutritional quality, and plant senescence likely constrained the diet of snow geese to a small number of food items. Because alternative foods may not be available, human disturbance should be minimized in areas that provide these forage species.

    In this work, the γ-ray spectrometry is introduced to measure the activity concentration of 210 Pb in the environmental samples .By measuring the γ-ray of 210 Pb at 46.5 keV, the activity concentration of 210 Pb is determined in aerosol sample collected by cellulose acetate membranes filter and in water sample in Marinelli Beaker .The great advantage of this method is rapid , non-destructive , without preliminary chemical separation and sample preparation , but it is limited by the low emission and high self -absorption probability of this line at such low energy .The key point in the analysis is the efficiency calibration of this line .The experimental results show that the gamma ray spectrometry can be employed to determine the 210 Pb activity in the environmental sample.%介绍了用γ谱仪测量环境中210 Pb的分析方法。用醋酸纤维滤膜采集气溶胶样品,或用马林杯直接封装环境水样,在γ谱仪上测量210 Pb发射的46.5 keV射线,通过解谱分析技术获得210 Pb的放射性活度。该方法具有快速、非破坏性、无需化学分离及样品处理等优点,但存在低γ发射几率及射线能量低导致的高自吸收等不足,分析的关键在于γ谱仪效率刻度。实验结果表明:γ谱法可用于环境样品中210 Pb的放射性活度测量。

    In Africa about 133 million people lived with disabilities which were mainly the sequelae of infectious disease, war or trau-ma accidents, single organ dysfunction, refractive error and some others. Medical rehabilitation and community-based rehabilitation could only meet 5%~55%of their rehabilitation needs. Weak infrastructure, poverty and lack of funds, negative attitudes and the monotonous hu-man and culture environments restricted the development of rehabilitation medicine in Africa. Chinese model of rehabilitation medicine seemed to be suitable for Africa. Chinese medical teams in Africa could do a lot in admissions of the disabled, improving hardware condi-tions, training of professionals, developing new technology and expanding the prestige of rehabilitation medicine.%非洲约有1.33亿残疾人,多由感染性疾病、战争创伤事故、单器官功能障碍、屈光不正等引起。非洲的医学康复与社区康复只能满足其康复需求的5%~55%,基础设施薄弱、贫穷及资金匮乏、工作不落实、人文环境单调等是制约康复医学发展的因素。中国康复医学模式适合非洲,医疗队在接诊康复患者、改善硬件条件、培训专业人员、开展新技术、制定新流程及扩大康复医学的影响上可以做很多工作。

    2012-01-01

    We study the well-known sociological phenomenon of gang aggregation and territory formation through an interacting agent system defined on a lattice. We introduce a two-gang Hamiltonian model where agents have red or blue affiliation but are otherwise indistinguishable. In this model, all interactions are indirect and occur only via graffiti markings, on-site as well as on nearest neighbor locations. We also allow for gang proliferation and graffiti suppression. Within the context of this model, we show that gang clustering and territory formation may arise under specific parameter choices and that a phase transition may occur between well-mixed, possibly dilute configurations and well separated, clustered ones. Using methods from statistical mechanics, we study the phase transition between these two qualitatively different scenarios. In the mean-field rendition of this model, we identify parameter regimes where the transition is first or second order. In all cases, we have found that the transitions are a co...

    Full Text Available This article reexamines cultural curriculum and marginalized youth at-risk for gang involvement. While the literature expresses various approaches to addressing the gang problem in the United States, including comprehensive gang initiative models, get tough policies, and comprehensive peace campaigns to stop the violence. All of these initiatives have seemingly done little to stop gang membership among school age youth. Education has proven to be the most significant means to improve an individual’s life chances, but African American students, in particular, are performing worse than Whites on an average. If society is to reach these youth through education, we argue that a new classroom pedagogy is needed. To this aim, creating a culturally responsive classroom through hip hop may be the answer to engage troubled youth in the classroom.
