    Children's work and schooling - does gender matter? : evidence from the Peru LSMS panel data

    Get PDF
    Using panel data from Peru, the author investigates the determinants of the allocation of boys'and girls'time to schooling, housework, and income-generating activities. Specifically, she explores whether sickness, female headship, access to infrastructure, and employment of women in the household have different impacts on the time use of boys and girls. Girls mostly engage in housework, and boys mostly work outside the home. As a work activity, housework responds to economic incentives and constraints. The author's econometric findings suggest that changes in household welfare affect girls'work and schooling more than boys'. Even though boys'and girls'educational attainment rates are the same, girls'education responds more to changes in household welfare than does boys'. Similarly, girls are more likely than boys to adjust their home time in response to changes in adult female employment and to sickness of household members. Lack of access to energy infrastructure lowers the educational attainment of both boys and girls but has little affect on their labor. The traditional approach to the determinants of child labor and education excludes housework and may understate children's time use, particularly that of girls. It may therefore also overlook an important gender dimension of education policy. Safety nets that protect household incomes from employment shocks and sickness, and childcare programs that allow women to work, would reduce the likelihood of girls being pulled out of school.Scientific Research&Science Parks,Health Monitoring&Evaluation,Gender and Development,Public Health Promotion,Children and Youth,Youth and Governance,Health Monitoring&Evaluation,Adolescent Health,Street Children,Children and Youth

    Modelling the intermixing effects in highly strained asymmetric InGaAs/GaAs quantum well

    Full text link
    In this work, we have theoretically investigated the intermixing effect in highly strained In0.3_{0.3}Ga0.7_{0.7}As/GaAs quantum well (QW) taking into consideration the composition profile change resulting from in-situ indium surface segregation. To study the impact of the segregation effects on the postgrowth intermixing, one dimensional steady state Schrodinger equation and Fick's second law of diffusion have been numerically solved by using the finite difference methods. The impact of the In/Ga interdiffusion on the QW emission energy is considered for different In segregation coefficients. Our results show that the intermixed QW emission energy is strongly dependent on the segregation effects. The interdiffusion enhanced energy shift is found to be considerably reduced for higher segregation coefficients. This work adds a considerable insight into the understanding and modelling of the effects of interdiffusion in semiconductor nanostructures.Comment: 6 pages, 4 figure

    You gotta fight for your right(s): street harassment and its relationship to gendered violence, civil society , and gendered negotiations

    Get PDF
    This Thesis explores particular dimensions of street harassment against women in Cairo, Egypt investigated in three ways: Paying attention to how gender, race and class intersect, I found Egyptian and foreign women utilize various strategies in order to cope with street harassment such as verbal silence, modifications their bodily movements and appropriated styles of dress which in turn strives to maintain a sort of mobile private space that maintains their respectability. However, paying attention to the discontinuities found within normative ideas of gender, I argue that women at times transgress the boundaries of it and fight back to the harassment they unwillingly receive by employing violence and class-motivated forms of protectionism. Secondly, I explored the relationship between street harassment and masculinity. I identify how social constructs of gender in Egyptian society are used to reinforce and at times encourage particular behaviors among men and women. Those notions normalize violent behaviors of men unto women and restate an ideal women\u27s subjectivity to simultaneously remain silent and honorable. Arguably, street harassment against women is a form of violence, which, enacted by men serves to reinforce notions of a hegemonic masculinity. I like others, argue that the preoccupation with women\u27s bodies in and outside of the Middle East, de-limits both their rightful access to public space and to safety. Lastly, I examined civil society\u27s role in particular feminist desires of space. Focusing on an Egyptian NGO, The Egyptian Center for Womenâ s Rights-ECWR, I examined their relationship to the Egyptian state and their role in aligning themselves with particular Western feminist ideals. I grapple with their overarching platform of naming harassment, \u27Sexual Harassment.\u27 I maintain that although they champion women\u27s rights, they must be careful in how they construct particular terminologies. I argue that the problem needs to be understood and tackled in cultural-specific terms designed by Egyptian women themselves. If not done carefully, we fall into the theoretical trap of representational politics of non-Western women and Egyptian society will continue to be split in believing that harassment is a problem worth solvin

    Metabarcoding identification of botanical origin of bee-collected pollen samples: comparison of ITS2 reference database performance before and after enrichment with sequences of bee plant species

    Mestrdo de dupla diplomação com a High Institute of Biotechnology of MonastirSequence analysis of complex DNA samples is an important approach to monitoring species distribution in biodiversity and population studies. Although many traditional methods can be used to identify bee plant resources (e.g., direct observations, microscopy), high-throughput sequencing technologies have transformed our ability to explore more complex plant communities without necessity of experts and in a time cost effective-manner, in comparison with the classical techniques. Recently, metabarcoding, which combines DNA barcoding with high-throughput sequencing, of bee pollen has been used to successfully identify which plants bees are foraging on. This is achieved most commonly by sequencing short, conserved marker genes amplified with universal PCR primers. The ITS region has already been proposed and mainly used as universal barcode marker for plants. ITS sequences are often compared against an annotated reference sequence database to identify the likely taxonomic origin of each sequence with as much specificity as possible. So, accurate and specific taxonomic information is an important step in pollen metabarcoding analysis. The aim of this study was to assess performance of the ITS2 reference database before and after enrichment with sequences of bee plant species collected from across Europe. A total of 100 plant samples were collected in six countries and were identified morphologically at the species level. The DNA of these plant samples was extracted and then Sanger-sequenced for the ITS2 region. The sequences were curated and blasted against ITS2 sequences in GenBank to obtain taxonomic identification and assess similarity with the morphological identification. Next, a reference database of ITS2 sequences was generated using the 100 sequences. The newly-developed sequences were added to a comprehensive ITS2 reference database publicly available and the performance of the two databases (with and without the 100 sequences generated herein) was compared on a set of 108 mixed pollen samples that were identified by metabarcoding and classical palynology. The analyses of the data showed a positive correlation (r>0.7; P<0.05) between the two methods at both family (most countries) and genus levels (one third of countries), even though metabarcoding identified 12 families and 26 genera and palynology 13 families and 22 plant genera. Classification of mixed pollen samples, using the ITS2 database before enrichment with the new sequences developed herein, retrieved (i) 76 and 67 families before and after removing taxa that are not present in Europe, respectively, and (ii) 69 families after enrichment. At the genus level, before database enrichment, there were 230 and 214 genera identified before and after removing taxa that are not present in Europe, respectively, and 216 genera after enrichment. Results showed a positive correlation (r>0.9; P<0.001) between the different databases, but variation in the number of families and genera was noticed, which indicates an increase in the resolution and accuracy of classification. This study thus offers improvements in the ITS2 metabarcoding with more available sequences in the reference dataset providing heightened sensitivity and resolution.A análise de sequências de amostras complexas de DNA é uma abordagem importante na monitorização da distribuição de espécies em estudos populacionais e de biodiversidade. Embora possam ser utilizados métodos tradicionais como meio de identificar plantas melíferas, como por exemplo, observações diretas, microscopia, entre outros, as tecnologias de sequenciação de última geração transformaram a nossa capacidade de explorar floras mais complexas sem que haja a necessidade de recorrer a especialistas, tornando se também numa técnica mais económica, quando comparada às tecnologias clássicas. O metabarcoding, uma técnica que combina DNA barcode com sequenciação de última geração, tem sido usado para a identificação das espécies botânicas mais visitadas pelas abelhas forrageiras através da análise de pólen colhido pelas mesmas. Esta técnica baseia-se na sequenciação de marcadores genéticos de tamanho curto e que se localizem em zonas de DNA conservadas. A amplificação destes fragmentos é feita recorrendo a primers universais, para uma maior abrangência botânica. O ITS, uma região intergénica ribossomal, foi proposta e largamente utilizada, principalmente, como marcador genético universal em plantas. As sequências deste fragmento são, frequentemente, comparadas com uma base de dados de referência para que se estabeleça a identificação mais provável, e com a máxima especificidade possível, da origem taxonómica de cada fragmento sequenciado. Assim, informações taxonómicas precisas e específicas são um passo importante na análise de misturas de pólen colhidas pelas abelhas forrageiras através do metabarcoding. O objetivo deste estudo foi avaliar o desempenho da base de dados ITS2 de referência antes e depois do enriquecimento com sequências de espécies de plantas melíferas colhidas pela Europa. Um total de 100 amostras de plantas foram colhidas em seis países e foram identificadas morfologicamente ao nível da espécie. Procedeu-se à extração do DNA e sequenciação pelo método de Sanger da região ITS2. As sequências foram curadas e alinhadas com sequências do GenBank, através de um BLAST, para obter a identificação taxonómica e avaliar a similaridade com a identificação morfológica. Em seguida, uma base de dados ITS2 de referência foi gerada usando as 100 recém-desenvolvidas sequências. Estas foram adicionadas a uma vasta base de dados da região ribossomal, que está publicamente disponível, e o desempenho das duas (com e sem as 100 sequências geradas aqui) foi comparado num conjunto de 108 amostras de pólen colhido por abelhas, e previamente identificadas por metabarcoding e palinologia clássica. As análises mostraram uma correlação positiva (r> 0,7; P <0,05) entre os dois métodos para dois níveis taxonómicos, família (maioria dos países) e género (um terço dos países), embora o metabarcoding tenha identificado 12 famílias e 26 géneros e a palinologia 13 famílias e 22 géneros de plantas. A classificação das amostras de pólen, usando a base de dados ITS2 antes do enriquecimento com as novas sequências aqui desenvolvidas, recuperou (i) 76 e 67 famílias antes e depois da remoção dos táxons que não estão presentes na Europa, respetivamente, e (ii) 69 famílias após o enriquecimento. Ao nível do género, antes do enriquecimento da base de dados, havia 230 e 214 géneros identificados antes e depois da remoção dos táxons que não estão presentes na Europa, respetivamente, e 216 géneros após o enriquecimento. Os resultados mostraram uma correlação positiva (r> 0,9; P <0,001) entre as diferentes bases de dados, mas foi observada uma variação no número de famílias e géneros, o que indica um aumento na resolução e precisão da classificação. Este estudo oferece, assim, melhorias no metabarcoding da região ITS2 com mais sequências disponíveis no conjunto de dados de referência, proporcionando uma maior sensibilidade e resolução.This study was developed in the framework of the international project “INSIGINA: Pilot study on environmental monitoring of pesticide use through honey bees”, SANTE/E4/SI2.788418-SI2.788452-INSIGINIA-PP-1-1-2018, financed by the Health and Food Safety Directorate General, European Commission

    How does working as a child affect wage, income, and poverty asan adult?

    The authors use a unique data set on adult earnings in Brazil to study how child labor affects adult earnings through its impacts on work experience, years of schooling, and human capital attained per year of schooling. Adding up these positive and negative effects, their empirical findings suggest that adults who entered the labor market before age 13 earn 20 percent less per hour, have 26 percent lower incomes, and are 14 percent more likely to be in the lowest two income quintiles. Overall, child labor raises the probability of being poor later in life by 13 percent to 31percent. These magnitudes are large. On the other hand, while child labor reduces the productivity of schooling, the net effect of an additional year of schooling on adult wages is still positive, even if the child works while in school. Consequently, policies which delay dropping out of school, even as the child works, appear to be effective at mitigating adult poverty. This report is a promising first step toward a better understanding of the theoretically ambiguous impact of early labor market entry on lifetime labor market outcomes and the dynastic poverty traps discussed below.
