Can a small social pension promote labor force participation? Evidence from the Colombia mayor program

One of the primary motivations behind the establishment of noncontributory pension programs is to allow beneficiaries to retire from the labor force. Yet their aggregate effects may be more complex. One such program, Colombia Mayor, stands out for its low eligibility age. Given that beneficiaries are not required to leave the labor force, it practically constitutes a fixed income—an unconditional cash transfer of sorts—to a still economically active population. Using panel data and instrumental variable techniques, this paper shows that the effect of this program has been to raise the labor force participation of relatively younger, particularly male, beneficiaries. This increase occurred precisely in the occupations with characteristics that are likely to require some up-front investment and for the comparatively poorer. We conclude that the transfer effectively loosened the liquidity constraints to remaining in these occupations. No such effect is found for older beneficiaries

High incidence of violent crime may drive geographic chronic poverty

Exposure to crime disproportionately affects poorer communities. In the case of Mexico, poorer municipalities have fewer resources for comping with the associated risks of high incidence of crime, leaving them trapped in poverty

Association between the serum concentration of triiodothyronine with components of metabolic syndrome, cardiovascular risk, and diet in euthyroid post-menopausal women without and with metabolic syndrome

PURPOSE: To determine the association between the serum concentration of triiodothyronine (T3) with components of metabolic syndrome (MetS), cardiovascular risk (CVR), and diet in euthyroid post-menopausal women without and with MetS. METHODS: A cross-sectional study was performed in 120 voluntary women of an indigenous population from Tlaxcala-México. Euthyroid status was assessed measuring the serum concentration of thyrotropin (TSH) and thyroid hormones, while that of estradiol was measured to confirm the postmenopausal condition. MetS was diagnosed using the American Heart Association/National Heart, Lung, and Blood Institute Scientific Statement (AHA/NHLBI) criterion. Estimation of CVR was calculated based on the Framingham scale. Diet components were evaluated based on survey applications. Correlations, logistic regression analyses, ANOVA or Kruskall-Wallis, and chi-square tests were used to determine significant differences (P ≤ 0.05) between women without MetS and women with MetS having different serum concentrations of T3. RESULTS: Triiodothyronine was positively correlated with insulin but negatively correlated with glucose, high-density lipoprotein cholesterol (HDL-C), and CVR. Compared to women without MetS, women with MetS and low-normal T3 concentration showed a high risk for hyperglycemia and moderate/high risk for CVR. In contrast, a high-normal T3 concentration increased the risk to have a big waist circumference, a high concentration of HDL-C, and insulin resistance. Diet analysis showed a high grade of malnutrition in women from all groups. The intake of calories was positively affected by the T3 concentration, albeit it did not affect the extent of malnutrition. CONCLUSIONS: In contrast to concentrations of TSH, total thyroxin (T4), and free T4, the concentration of serum T3 was strongly correlated with cardio-metabolic variables in euthyroid postmenopausal women. In comparison to women without MetS, a high-normal serum concentration of T3 in women with MetS is positively associated with reduced glycaemia and CVR but negatively related to body mass index (BMI), insulin, insulin resistance, and HDL-C. Although the analyzed population had a nutritional deficiency, both calories and iron intake were positively affected by the T3 concentration. Our results suggest the necessity of health programs monitoring T3 in old people in order to treat hyperglycemia, cardio-metabolic components, and the ageing anorexia

Tracing the Local Impacts of Exports on Poverty and Inequality: The Case of Mexico

Evidence about the effect of exports on welfare at the local level is scarce. Using a unique dataset of international trade and poverty maps for almost 2,000 Mexican municipalities between 2004 and 2014, the study presented in this paper provides new evidence on the impact of a significant rise in exports on poverty and inequality at the local level. The analysis implements an instrumental variable approach that combines the initial structure of exports across municipalities with global trends in exports from developing to developed countries by sector. The results show that a 10 percent increase in the ratio of exports to workers reduces income inequality measured by the Gini coefficient by 0.17 points (using a 0 to 100 scale), but no significant effects on poverty reduction or average household incomes are identified. The lack of impacts on average incomes is driven by a rise in the supply of labor at the local level because municipalities with higher export growth experienced an increase in labor force participation and attracted more net migration, particularly of unskilled workers. Therefore, while total labor incomes grew in response to an increase in exports, average labor incomes per worker did not change. Declining remittances also blunted the effect of growing exports on household incomes.Centro de Estudios Distributivos, Laborales y Sociale

Labor informality and market segmentation in Senegal

Understanding the selection of workers into informality is a policy priority to design programs to increase formalization across Sub-Saharan Africa, where nine out of ten workers are informal. This paper estimates a model of self-selection with entry barriers into the formal sector to identify the extent of involuntary informality in Senegal, a representative country in terms of levels of informality in West Africa and with one of the most rigid labor markets in the world. Results show that the desire of being formal is greater for workers with formal education, married and with a lower proportion of children under the age of 5 living in the household. The individual's preference for the formal sector also grows with age at a decreasing rate. Results also show that labor informality is mainly a voluntary phenomenon with 30 percent of informal workers being involuntarily displaced into the informal sector. Results are robust to different model specifications, definitions of labor informality and heterogenous groups of workers.Centro de Estudios Distributivos, Laborales y Sociale

Evaluación de un consorcio microbiano en la remoción de Cr (VI) en agua sintética

La biorremediación es una técnica cada vez más utilizada para la remoción de metales pesados como el cromo hexavalente Cr (VI) en agua, este metal es de gran prioridad ya que principalmente se incorpora en el agua debido a la descarga de desechos industriales, es de gran persistencia y altamente tóxico. Debido a lo anterior en este trabajo se presentan los resultados de un proceso de biorremediación de Cr (VI) en agua sintética donde se compara la eficiencia de Pseudomonas putida contra Saccharomyces cerevisiae por separado mediante biosorción y bioacumulación, en donde las remociones más altas se obtuvieron con el proceso de bioacumulación, siendo de 39.03% y 75.17%, respectivamente. Por lo que posteriormente se utilizó esta técnica para la evaluación de los microorganismos en conjunto, donde se removió un 94.06% de Cr (VI). La cuantificación del metal se realizó mediante espectrofotometría de ultravioleta visible (UV-vis).Bioremediation is an increasingly adopted technique used in the removal of heavy metals, such as hexavalent chromium (Cr (VI)) in water, which is a high priority metal, since it is incorporated mainly in water due to the discharge of industrial waste. It is considerably persistent and highly toxic. Therefore, in this work the results of a bioremediation process of Cr (VI) in synthetic water are presented, where Pseudomonas putida against Saccharomyces cerevisiae through biosorption and bioaccumulation are compared separately. The highest removal was obtained with the bioaccumulation process, being 39.03% and 75.17%, respectively. Consequently, this technique was used for the evaluation of both microorganisms together, where 94.06% of the Cr (VI) was removed. The quantification of metal was done by using ultraviolet-visible spectrophotometry (UV-vis)

High Estradiol Differentially Affects the Expression of the Glucose Transporter Type 4 in Pelvic Floor Muscles of Rats

Purpose To characterize the relationship between serum estradiol levels and the expression of glucose transporter type 4 (Glut4) in the pubococcygeus and iliococcygeus muscles in female rats. Methods The muscles were excised from virgin rats during the metestrus and proestrus stages of the estrous cycle, and from sham and ovariectomized rats implanted with empty or estradiol benzoate–filled capsules. The expression of estrogen receptors (ERs) was inspected in the muscles at metestrus and proestrus. Relative Glut4 expression, glycogen content, and serum glucose levels were measured. Appropriate statistical tests were done to identify significant differences (P≤0.05). Results The pubococcygeus and iliococcygeus muscles expressed ERα and ERβ. Glut4 expression and glycogen content in the pubococcygeus muscle were higher at proestrus than at metestrus. No significant changes were observed in the iliococcygeus muscle. In ovariectomized rats, the administration of estradiol benzoate increased Glut4 expression and glycogen content in the pubococcygeus muscle alone. Conclusions High serum estradiol levels increased Glut4 expression and glycogen content in the pubococcygeus muscle, but not in the iliococcygeus muscle

Compromising between European and US allergen immunotherapy schools: Discussions from GUIMIT, the Mexican immunotherapy guidelines

Background: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice. In other parts of the world, extracts from both regions and local ones are commercialized, as in Mexico. Here, local experts developed a national AIT guideline (GUIMIT 2019) searching for compromises between both schools. Methods: Using ADAPTE methodology for transculturizing guidelines and AGREE-II for evaluating guideline quality, GUIMIT selected 3 high-quality Main Reference Guidelines (MRGs): the European Academy of Allergy, Asthma and Immunology (EAACI) guideines, the S2k guideline of various German-speaking medical societies (2014), and the US Practice Parameters on Allergen Immunotherapy 2011. We formulated clinical questions and based responses on the fused evidence available in the MRGs, combined with local possibilities, patient's preference, and costs. We came across several issues on which the MRGs disagreed. These are presented here along with arguments of GUIMIT members to resolve them. GUIMIT (for a complete English version, see Supplementary data) concluded the following: Results: Related to the diagnosis of IgE-mediated respiratory allergy, apart from skin prick testing complementary tests (challenges, in vitro testing and molecular such as species-specific allergens) might be useful in selected cases to inform AIT composition. AIT is indicated in allergic rhinitis and suggested in allergic asthma (once controlled) and IgE-mediated atopic dermatitis. Concerning the correct subcutaneous AIT dose for compounding vials according to the US school: dosing tables and formula are given; up to 4 non-related allergens can be mixed, refraining from mixing high with low protease extracts. When using European extracts: the manufacturer's indications should be followed; in multi-allergic patients 2 simultaneous injections can be given (100% consensus); mixing is discouraged. In Mexico only allergoid tablets are available; based on doses used in all sublingual immunotherapy (SLIT) publications referenced in MRGs, GUIMIT suggests a probable effective dose related to subcutaneous immunotherapy (SCIT) might be: 50–200% of the monthly SCIT dose given daily, maximum mixing 4 allergens. Also, a table with practical suggestions on non-evidence-existing issues, developed with a simplified Delphi method, is added. Finally, dissemination and implementation of guidelines is briefly discussed, explaining how we used online tools for this in Mexico. Conclusions: Countries where European and American AIT extracts are available should adjust AIT according to which school is followed
