Thus, first the Social Economy is presented as an important alternative to creating and promoting employment, which seeks to combine economic and social objectives in the development of activities. Subsequently, focusing on labor companies, updated its importance in the regional economy for later data and through the analysis of two samples are available, set the attributes or most significant characteristics of these entrepreneurs.

Capacidades institucionales y ejecución de políticas sociales: Programas de salud y nutrición materno-infantil en Argentina y Chile (1930-2000)

Este artículo compara los programas de salud materno-infantil en Argentina y Chile, prestándole especial atención a las características institucionales de largo plazo y las tendencias neoliberales presentes en la organización de las reformas sociales de las décadas de 1980 y 1990. Objetivo: Llevar a cabo un estudio comparativo sobre las transformaciones de los programas de salud y nutrición materno-infantil, teniendo en cuenta tres aspectos conectados entre sí: las políticas sociales, las capacidades institucionales y la ejecución de políticas. Metodología: El análisis documental realizado en este artículo se enmarca en el modelo de fuerza estructural de Carmelo Mesa-Lago y en el modelo de la estructura centrada en el estado de Theda Skocpol. Conclusiones: A pesar de la relativa similitud en los lineamientos de las políticas de salud aplicadas en ambos países, los contrastes en las características institucionales a largo plazo (los programas chilenos abordaron la salud materno-infantil de forma más eficiente que los argentinos) representan la mayor parte de la variación en el proceso general de aplicación de las reformas y el desempeño de las políticas de salud materna e infantil.

How often parametrial involvement leads to post-operative adjuvant treatment in locally advanced cervical cancer after neoadjuvant chemotherapy and type C radical hysterectomy?

OBJECTIVE Parametrial involvement (PMI) is one of the most important factors influencing prognosis in locally advanced stage cervical cancer (LACC) patients. We aimed to evaluate PMI rate among LACC patients undergoing neoadjuvant chemotherapy (NACT), thus evaluating the utility of parametrectomy in tailor adjuvant treatments. METHODS Retrospective evaluation of consecutive 275 patients affected by LACC (IB2-IIB), undergoing NACT followed by type C/class III radical hysterectomy. Basic descriptive statistics, univariate and multivariate analyses were applied in order to identify factors predicting PMI. Survival outcomes were assessed using Kaplan-Meier and Cox models. RESULTS PMI was detected in 37 (13%) patients: it was associated with vaginal involvement, lymph node positivity and both in 10 (4%), 5 (2%) and 12 (4%) patients, respectively; while PMI alone was observed in only 10 (4%) patients. Among this latter group, adjuvant treatment was delivered in 3 (1%) patients on the basis of pure PMI; while the remaining patients had other characteristics driving adjuvant treatment. Considering factors predicting PMI we observed that only suboptimal pathological responses (OR: 1.11; 95% CI: 1.01, 1.22) and vaginal involvement (OR: 1.29 (95%) CI: 1.17, 1.44) were independently associated with PMI. PMI did not correlate with survival (HR: 2.0; 95% CI: 0.82, 4.89); while clinical response to NACT (HR: 3.35; 95% CI: 1.59, 7.04), vaginal involvement (HR: 2.38; 95% CI: 1.12, 5.02) and lymph nodes positivity (HR: 3.47; 95% CI: 1.62, 7.41), independently correlated with worse survival outcomes. CONCLUSIONS Our data suggest that PMI had a limited role on the choice to administer adjuvant treatment, thus supporting the potential embrace of less radical surgery in LACC patients undergoing NACT. Further prospective studies are warranted.

From mundane to smart: Exploring interactions with ‘smart' design objects

In addition to functional and technological features, the role of augmented objects should also be seen in terms of how effectively they fit into the everyday practices of users and how they enhance users' experiences. In this article, the authors introduce a low-tech, internet-of-things technology called CAM (Cooperative Artefact Memory) that is used as a collaborative tool in design studio environments. CAM works as an object memory technology and allows industrial and product designers to collaboratively store relevant information onto their physical design objects, such as sketches, collages, storyboards, and physical mock-ups in the form of messages, annotations and external web links. In the context of this study, CAM serves as an important probing device to understand designers' interaction and experiences with augmented design objects, in their natural environment. The authors carried out a small-scale field trial of CAM in an academic design studio, over three student design projects. In this article, they discuss the findings of their field trial and show how CAM was used by the participants, how it was integrated into the design process and how it was appropriated for different purposes. The authors also found that CAM supported coordination and awareness within the design teams, yet its serendipitous and asynchronous nature facilitated creative and playful interactions between team members. In general, the results show how CAM transformed mundane design objects into “smart” objects that made the creative and playful side of cooperative design visible.

稠油污染土壤高级氧化-生物耦合修复研究

稠油中的胶质和沥青质是导致稠油污染土壤难以彻底降解的关键要素，而目前传统的生物修复方法很难满足其处理要求。针对这一难题，本文研究了高级氧化-生物耦合修复方法处理稠油污染土壤，达到了使稠油中胶质和沥青质高效去除的目的。 本文采用蛭石模拟土壤，研究稠油污染土壤的高级氧化（臭氧、芬顿）-生物耦合处理方法。分析了氧化时间、水土比、污染土壤陈化时间和污染浓度对臭氧氧化效率的影响，以及H2O2加入量和H2O2/Fe2+摩尔比对芬顿预处理效率的影响；同时优化了高级氧化与微生物混合菌之间的耦合条件；并根据稠油成分的变化，探讨了稠油降解机制。 实验结果表明，模拟稠油污染土壤的最佳臭氧-生物耦合条件为：臭氧氧化30min，生物段采用混合菌1降解14d，此时，土壤中总石油烃、饱和烃、芳烃、胶质和沥青质的降解率分别为60.78%、65.59%、82.74%、26.61％；芬顿-生物耦合处理的最佳条件为：H2O2 加入量为27ml，H2O2与Fe2+的摩尔比为10：1，此时，模拟土壤中稠油总石油烃、饱和烃、芳烃、胶质和沥青质的降解率分别为35.41%，9.33%，49.82%，45.19%。 高级氧化预处理不仅能够减小生物段负荷，而且能够提高胶质和沥青质的生物可利用性，微生物可将胶质和沥青质降解为饱和烃、芳烃或其他物质，降解效率取决于预处理的程度。高级氧化-生物耦合处理降解效率高于单独采用氧化预处理、生物处理效率，因而高级氧化-生物耦合修复方法是一种可行的稠油污染土壤修复方法。

青藏高原青稞淀粉资源的评价

青稞（Hordeum vulgare L.var．nudum Hook．f.），即裸大麦，是兼食用、饲用和酿造于一体的作物，有着重要的利用价值。淀粉是青稞籽粒中含量最多、最重要的碳水化合物，淀粉含量、直支淀粉比将会直接影响淀粉的功能特性，进而影响淀粉的应用领域。我国青藏高原青稞的栽培和食用历史悠久，特色青稞资源极其丰富。目前关于青藏高原青稞淀粉特性的报道还不多见，筛选和培育特色淀粉青稞利于拓展青稞的应用领域, 从而提高其经济价值。 本研究以114份青藏高原青稞品种(系)为实验材料，通过SDS-PAGE对材料的胚乳淀粉颗粒结合蛋白（SGAPs）进行分离，确定各蛋白的分子量大小、组合类型和多态性等。然后按照国标法测试材料的籽粒总淀粉含量和直链淀粉含量，通过微型糊化粘度仪分析相应的淀粉糊化特性，最后使用显微镜观察比较了青稞的淀粉颗粒形态特征。主要结果如下： 1、114种青稞中共分离出20种不同的SGAP条带，条带分子量为35.00～112.39 KDa，分布频率为12.28～97.37%。材料含有的SGAPs条带数从10到14不等，超过一半的材料含11种SGAP条带。20种条带形成16种组合类型，其中西藏地区青稞包含所有16个组合类型，四川地区青稞包含其中12个组合类型。青藏高原青稞籽粒淀粉颗粒结合蛋白的差异很大，遗传多样性丰富。 2、114份青稞的总淀粉含量、直链淀粉含量、直支淀粉比、峰值粘度、糊化温度和峰值温度的变幅分别为51.26～66.70%、14.64～29.74%、0.17～0.42、194～1135BU、58.8～65.2℃和81.4～92.4℃，相应的平均值分别为59.82%、23.60%、0.31、722.30BU、62.1℃和88.8℃。群体在总淀粉含量、直链淀粉含量、直支淀粉比、峰值粘度、糊化温度和峰值温度上的分布具有明显的正态性；所有胚乳淀粉体的淀粉粒都呈复粒结构。对西藏和四川的材料进行了分组比较， 两地区的青稞在直链淀粉含量和直支淀粉比上的差异达到显著水平。 3、筛选出18份具有特殊淀粉特性的青稞品种，其中5份材料的总淀粉含量超过65%，包括NB63-1、NB67、甘孜白六棱、98221-1和NB63；3份材料的直链淀粉含量大于29%，包括藏青85、藏青3号和喜马拉6号；8份材料的直支淀粉比小于0.25，包括99033-6、春青稞、阿坝330、Jan-03、米麦114、396、NB63-1和92013；7份材料的糊化温度低于60℃，同时材料的峰值粘度大于1000BU,并且峰值温度低于90℃，包括足捉春、Jan-03、阿坝330、米麦114、春青稞、20003和阿青5号。 4、各淀粉特性间存在高度相关性。直链淀粉含量和直支淀粉比与糊化温度成极显著正相关，与峰值粘度成极显著负相关，与A型淀粉粒数量和大小呈负相关。不同SGAPs组合的品种之间，淀粉含量和淀粉糊化特性间差异均达显著水平。SGAP2、SGAP5、SGAP6和SGAP7可能对籽粒直链淀粉含量、直支淀粉比和糊化温度有正向效应；SGAP3、SGAP9∼SGAP20可能对峰值粘度有正向效应。 本研究对青藏高原青稞淀粉资源进行了较为全面的评价，对该区青稞淀粉特性有了系统的认识。研究筛选出的特殊青稞品种可作为青稞育种和青稞淀粉工业应用的潜在资源，淀粉特性差异巨大的众多青稞品种也为拓宽青稞应用领域提供了丰富的资源保障。本研究对部分SGAPs在性质上的鉴定和功能上的初步推断为青稞材料的筛选提供了指导，也为品质育种提供了理论参考。 Hulless barley (naked barley, Hordeum vulgare L.) is a short- season, early maturing crop with a wide range of adaptation. It has been attracting more and more attention due to its superior nutrition and extensive industrial applications. Starch is the main ingredient in hulless barley seeds which makes up 65 percent of hulless barley’s dry weight. The ratio of the amylose/amylopectin and the size, shape, distribution of starch granules can affect the physico-chemical and functional properties of starch, which may turn affect its utilizations. The Qinghai-Tibet Plateau, which is located in southwestern China, is a typical area of vertical agricultural ecosystem and one of the barley origin centers with abundant hulless barley resources. There are little reports about hulless barley in Qinghai-Tibet Plateau at present. To screen and cultivate some characteristic hulless barley can improve its value. An improved SDS-PAGE was used to identify SGAPs combination of 114 hulless barley varieties. Starch content (total starch and amylose starch) was determined according to the standard methods GB5006-85 and GB/T 15683 using PerkinElmer M341 Precision Automatic Polarimeter and UV spectrophotometer 755B respectively. The pasting properties were measured by BRABENDER Micrio Visco-Amylo- Graph 803201. The morphology of starch granules were observed and compared with Axioplan 2 Imaging light microscopy. The following were the results obtained: 1. There were 20 major SGAPs presented in 114 varieties, with the molecular weight ranged from 35.00 to 112.39 KDa, and the frequencies ranged from 12.28% to 97.37%. The number of SGAP bands in each accession varied from 10 to 14, more than half of the population had 11 bands. There were 16 distinct SGAP patterns in the 114 varieties, the Tibet hulless barley had all of the 16 types and the Sichuan hulless barley had 12 types. The results indicated the Qinghai-Tibet Plateau hulless barley had a polymorphism of the SGAPs. 2. The ranges of the total starch content, amylose content, Am/Ap, peak viscosity, pasting temperature and peak temperature of the 114 hulless barley were 51.26～66.70%,14.64～29.74%,0.17～0.42,194～1135BU,58.8～65.2 and 81.4℃～92.4, with an average of ℃59.82%, 23.60%, 0.31, 722.30BU, 62.1 and 88.8,℃℃ respectively. The distributions of the total starch content, amylose content, Am/Ap, peak viscosity, pasting temperature and peak temperature were visibly normal school. All of the amyloplasts in endosperm of varieties showed bimodal size distributions.The main starch properties of hulless barley from Tibet and Sichuan were separated and compared, the differences on amylose content and Am/Ap were obvious. 3. Eighteen accessions which had special starch properties were screened out. Five accessions with total starch content beyond 65%, including NB63-1, NB67, Ganzibailiuleng, 98221-1 and NB63; three accessions, Zangqing85, Zangqing3 and Ximala6, with the highest amylose content (>29%); five accessions with Am/Ap less than 0.25, including 99033-6, Chun Qingke, A Ba 330, Jan-03, Mi Mai114, 396, NB63-1 and 92013; seven accessions had a pasting temperature under 60, ℃meanwhile their peak viscosity beyond 1000BU and their peak temperature under 90℃，including Zu Cuochun, Jan-03, A Ba 330, Mi Mai 114, Chun Qingke, 20003 and A Qing 5. 4. There were high correlations between starch properties. Amylose content and Am/Ap were positively correlated to pasting temperature, negatively correlated to peak viscosity, negatively correlated to the number and granule size of A-type granule. Different SGAP combinations caused significant diversities in starch content and pasting properties. SGAP2, SGAP5, SGAP6 and SGAP7 may have positive effect on amylose content, Am/Ap and pasting temperature; SGAP3, SGAP9∼SGAP20 may have positive effect on peak viscosity. Our research made a comprehensive evaluation on the hulless barley starch from the Qinghai-Tibet Plateau, we can get a systemic understanding. Some special accessions were screened out can be used on the hulless barley breeding lines and industries utilization.The combination of the SGAPs may become a criterion to evaluate the hulless barley endosperm starch quality. Consequently, the results will be good information for further studies on the hulless barley.

Cambios en el régimen de pensiones en Colombia y su efecto en el margen intensivo de la oferta laboral

En Colombia, como en muchos países de América Latina, en los años 80 y 90 se hicieron cambios importantes en los regímenes de pensiones. Este trabajo hace un análisis de uno de esos cambios en Colombia. El cambio consistió en aumentar el tiempo de cotización necesario para reclamar los beneficios pensionales y la inclusión del salario dentro de la fórmula del monto de pensiones. Para este propósito se estudia el impacto sobre la oferta laboral de un cambio exógeno en estas condiciones usando un diseño de regresión discontinua. Se encuentra un efecto positivo sobre las horas promedio trabajadas en la semana.

Parametric pension reform and the intensive margin of labor supply, evidence from Colombia

We analyze the effect of a parametric reform of the fully-funded pension regime in Colombia on the intensive margin of the labor supply. We take advantage of a threshold defined by law in order to identify the causal effect using a regression discontinuity design. We find that a pension system that increases retirement age and the minimum weeks during which workers must contribute to claim pension benefits causes an increase of around 2 hours on the number of weekly worked hours; this corresponds to 4% of the average number of weekly worked hours or around 14% of a standard deviation of weekly worked hours. The effect is robust to different specifications, polynomial orders and sample sizes.
