Workers'task specialization and division of labor are critical features of social insects'ecological success.It has been proposed that the division of labor relies on response threshold models:individuals varying their sensitivity(and responsiveness)to biologically relevant stimuli and performing a specific task when a stimulus exceeds an internal threshold.In this work,we study carbohydrate and protein responsiveness and their relation to worker task specialization in Vespula germanica,an invasive social wasp.The sucrose and peptone responsiveness of two different subcastes,preforagers and foragers,was determined by stimulating the antenna of the wasps with increasing concentrations of the solution and quantifying whether each concentration elicited a licking response.We studied responsiveness in five different ways:(1)response threshold,(2)concentration 50(concentration to which at least 50%of wasps responded),(3)maximum response,(4)mean scores and(5)median scores.Our results suggest that V germanica foragers are more sensitive to sucrose(lower thresholds)than preforager workers.However,we found no differences for peptone thresholds(i.e.,a protein resource).Nonetheless,this is the first study to investigate response thresholds for protein resources.The intercaste variation in sucrose responsiveness shown in our work contributes to the existing knowledge about response threshold theory as a mechanism for task specialization observed in V germanica.

Climate Change and Green Growth:A Perspective of the division of labor

引用

China & World Economy 2014年第5期22卷 93-116页

作者： Yongsheng Zhang Development Research Center of the State Council of China

This paper presents a new research agenda on climate change and green growth from the perspective of the division of labor in classical economics. The paper covers three major dimensions of green growth （i.e. carbon emissions, environmental proteetion and material resources use） and some related important topics, as well as the fresh policy implications of the new research agenda, Typical marginal analysis in a given structure of the division of labor suggests that ＂green＂ action is a burden to economic development. Therefore, climate negotiation has become a burden-sharing game and has reached a stalemate. New thinking is badly needed to rescue these negotiations and to drive a shift to a new ＂green growth＂ paradigm. The proposed new research agenda represents an effort to create a new narrative on climate change and green growth. Because the new research agenda can theoretically predict the possibility that a more competitive structure of the division of labor could be triggered by ＂＇green ＂＇ policy, it has promising policy implications for various important challenges facing us in the 21st century.

division of labor, perceived labor-related stress and well-being among European couples

引用

Open Journal of Preventive Medicine 2012年第4期2卷 452-460页

作者： Emma Hagqvist Katja Gillander Gadin Mikael Nordenmark Department of Health Sciences Mid Sweden UniversityOstersundSweden

Background: The objective of this study was to analyze how involvement in paid and unpaid work and perceived labor-related stress are related to the well-being of married or cohabiting men and women in Europe. Methods: Data from the European Social Survey round two has been used. The sample consists of 5800 women and 6952 men, aged between 18-65 years. Exposure variables were divided into labor involvement, time spent on paid and unpaid work, and labor-related stress. Multiple logistic regressions with 95 % confidence interval were used. Results: Women spent more hours on housework than men did, but fewer hours on paid work. Women tended to perceive higher degrees of housework-related stress than men did. Furthermore, women who experienced houseworkrelated stress tended to have higher odds of reporting a low level of perceived well-being than men, while men had higher odds of reporting a low level of perceived well-being when they experienced work/family conflicts. Conclusion: For both men and women, the perceptions of labor involvement are of more importance for the well-being than the actual time spent on paid and unpaid work. This implies that, when studying the relationship between labor involvement and well-being, perceived stress should be considered.

Brain transcriptional regulatory network for behavior demonstrates that brain gene expression in the honey bee can be accurately predicted from the expression transcription factors(TFs),but roles for specific TFs are less understood.Mushroom bodies(MBs)are important for learning,memory and sensory integration in the honey bee brain.A TFs,Mblk-1,expressed preferentially in the large-type Kenyon cells of the honeybee MBs is predicted to be involved in brain function by regulating transcription of its target genes in honey bee.However,its function and the mechanism of regulation in behavior of honey bee is still obscure.Here we show that Mblk-1 had significantly higher expression in the brains of forager bees relative to nurse bees.Mblk-1 was significantly inhibited in bees fed small interfering RNA.In addition,inhibition of Mblk-1 decreased sucrose responsiveness in foragers.Finally,we determined that Mblk-1 regulated the messenger RNA of AmGRl.These findings suggest that Mblk-1 may target AmGRl to regulate the sucrose responsiveness of foragers.

Eusocial insects display a caste system in which different castes are morpho-logically and physiologically specialized for different tasks.Recent studies have revealed that epigenetic modifications,including DNA methylation and histone modification,me-diate caste determination and differentiation,longevity,and polyethism in eusocial insects.Although there has been a growing interest in the relationship between epigenetic mech-anisms and phenotypic plasticity in termites,there is ltte information about differential expression levels among castes and expression sites for these genes in termites.Here we show royaltissuc-specific expression of epigenetic modification genes in the termite Reticulitermes speratus.Using RNA-seq,we identified 74 genes,including three DNA methyltransferases,seven sirtuins,48 Trithorax group proteins,and 16 Polycomb group proteins.Among these genes,15 showed king-specific expression,and 52 showed age-dependent differential expression in kings and queens.Quantitative real-time PCR revealed that DNA methyltransferase 3 is expressed specifically in the king's testis and fat body,whereas some histone modification genes are remarkably expressed in the king's testis and queen's ovary.These findings imply that epigenetic modification plays important roles in the gamete production process in termite kings and queens.

Aims in heterantherous plants,‘division of labor’among structurally dif-ferent stamens,i.***.pollinating and feeding functions,has been thought to reduce the evolutionary conflict of relying on pollen both as the carrier of male gametes and as the food for pollinators.The key to successful division of labor among different sets of stamens is the size match between stamens and legitimate pollinators,which results in the precise deposition of pollen onto specific locations on pollinator’s body and facilitates cross pollination.However,the potential impact of small illegitimate insects that are ubiquitous dur-ing the pollination process on the plant reproduction in heteranth-erous species has been largely neglected in previous studies and never been demonstrated experimentally.Methods Here,we investigated the functions of three different types of sta-mens in Commelina communis.The pollinator visitation,pollen removal and deposition were compared among flowers with dif-ferent types of anthers emasculated at two natural populations.moreover,the mating systems of C.communis in wild populations were estimated using microsatellite markers.Important Findingsour data showed that the main floral visitors for C.communis at the two studied populations were small illegitimate bees rather than legitimate pollinators,accounting for 77.5 and 92.2%of total flower visits,respectively.Flower manipulations in C.communis demon-strated that the two types of brightly yellow stamens separately func-tioned as‘deceptive attraction’and‘feeding’functions.although the brown inconspicuous stamens of C.communis with the largest amount of fertile pollen had the potential function in offering pollen for cross pollination,the high ratio of illegitimate visitation by small bees significantly affected the dispersal and deposition of pollen from the pollinating anthers,and subsequently decreased the levels of outcrossing(tm=0.23-0.32)in wild populations.our work further confirmed that the size match between pollinators and the floral morphology is the

This book review provides a multi-dimensional discussion on how the text(two editions)delivers not only factual information regarding European economic history,but focuses on the relevance and constructive uses of economic concepts,theories,and statistical analyses on issues regarding industrial economics.One major concern within industrial economics is the failure to recognize past experiences(the importance of history).Accordingly,the book contains a considerable amount of discussion about the problems and changes in the history of economic distribution associated with specific locations of economic activities,income,resources,production,international economic integration,and spatial economic activities in Europe.Furthermore,economic issues related to the international relationship between Europe and some developing countries are also elaborated.This book review serves as more than a summary:it highlights several intellectual and research-oriented aspects of the book that may benefit studies of economic industrialization and the humanities and social sciences more broadly.In particular,several aspects are evaluated,suggesting the extent of its comprehensiveness and the important data provided in the book.Finally,certain differences observed between the first and second editions of the book are also acknowledged and explained.

Gender Issues in Household-based Bamboo Industries:A Case Study of Two Villages in Xinping County,Yunnan Province of China

引用

Chinese Forestry Science and Technology 2004年第4期 54-62页

作者： HUANG Shineng YANG Lingyun (Elsie YANG) Research Institute of Tropical Forestry, Chinese Academy of ForestryGuangzhou 510520, P.R.China International Tropical Timber Organization, Yokohama, Japan

A qualitative gender assessment of household-based bamboo industries was conducted in Zhuyuan and Lagadi villages in Laochang Township, Xinping County in Southwest China’s Yunnan Province. Results showed that both women and men were actively involved in the production and marketing of bamboo products in the two villages. There were gender differences in bamboo-based rural industries that were closely associated with the ethnic habits, traditional norms of the rural society, the differences of educational levels that women and men achieved, and the gender blind-spots in the enforcement of laws and policies. It is evident that women were "equal" partners in the production of bamboo products, but "unequal" when the rights of access to and control over resources and personal independence are concerned. Suggestions are made to achieve a gender-balanced production system of bamboo products in rural areas of bamboo producing counties in Yunnan Province, China.

台湾银行自1899年于台北成立后，便不断向邻近的华南地区扩张势力。伴随业务的推进，1906年台湾银行开始谋划在上海设立营业点，企图将势力进一步向华东地区和长江流域扩展。但此计划却意外地遭到日本大藏省的极力反对。直至1911年，因台湾出现严重的糖业过剩危机，借助台糖外销中国大陆的“机遇”，上海分行才最终得以成立。通过探究上海分行设立的曲折经历，可发现其背后深受近代日本对国策银行的“分业主义”指导方针、以及日本在东亚“北进南守”扩张政策等多重因素的影响。上海分行的创立，成为日据殖民地的台湾银行向中国大陆金融侵略过程中的一个重大转折点。
