气候的历史与历史气候研究

寨堡是我国古代重要的军事防御性聚落，其修筑的时间、空间皆与区域的战争形势有着较大关系。清代四川省由于多次大规模战乱，迫使乡民修筑了数以千计的寨堡。寨堡的命名主要可分为因自然地理条件和因人文社会因素两大类，前者包括地形、水文、土石、植物等，后者包括姓氏、寺观、神祇、嘉名、人物、神话、形象、纪事等。寨名包含了丰富的文化内涵，体现出了寨堡的选址、用材、作用、历史、精神等内容。     

Reflections on grounding firm innovation and viability

Entrepreneurial activity unfolds in a dynamic environment that challenges business viability. We utilize grounded theory as a novel type of reflection to explain and interpret whether and how innovation can afford survival benefits to firms. The premise is the application of a methodological approach with reflexive properties to advance scientific rigor in “reflections.” The idea underlying our reflection was to use innovation as the point of departure, review the literature, conceptualize ideas, and finally link the concepts that emerged as components of a framework. Our view of the firm resembles a viable entity that changes, constantly striving to meet and balance internal potentials and external complexities, while innovation per se involves change that is made possible by entrepreneurship. We bring together our personal and professional backgrounds and implement the European scholarly tradition on innovation and Viable Systems approach to scrutinize innovation’s interactions and relations. We linked boundary conditions, opportunities, and complementary assets to innovation. Effectively, our analysis conceptualizes innovation as autopoiesis in entrepreneurship and demonstrates its central role as the vehicle to exploit changes that ensure firm viability.     

Travail et normes comptables internationales: une question de justice sociale

En tant que garante internationale de la justice sociale, l'OIT se trouve confrontée à une révolution comptable mondiale, parachevée par les normes comptables internationales (IAS-IFRS). La comptabilité mesurait autrefois l'économie en rapport avec les capacités et les responsabilités des travailleurs et de ceux qui en disposent. C'est aujourd'hui l'exact opposé: les normes IAS-IFRS ont perdu le sens de la mesure du travail et de l'entreprise en se référant au concept abstrait d'une entité cybernétique capable d'incessantes réorganisations, au prix d'inégalités sans limites. L'auteur en dénonce les incohérences et démontre la nécessité de redonner au travail toute sa valeur comptable.     

Labour and international accounting standards: A question of social justice

As the international guardian of social justice, the ILO is witnessing a global revolution in accounting, which has culminated in international accounting standards (IAS-IFRS). Previously, accounting measured the economy in relation to the capacities and responsibilities of workers and their employers. Today, the exact opposite is the case: the IAS-IFRS no longer measure work and enterprises, referring instead to the abstract concept of a cybernetic entity capable of constant restructuring, at the cost of unprecedented inequality. The author points to the incoherence of this system and to the need to restore the full carrying value of labour.     

Call centres and job satisfaction in Italy: employment conditions and socio-biographical patterns

ABSTRACT

The article examines job satisfaction in 21 Italian call centres. The results of research carried out on 1715 handlers indicate how dissatisfaction prevails among call centre representatives (CCRs) and how it is influenced by aspects related to some organisational characteristics (service delivered, size and organisational typology), on one side, and to different aspects of working conditions (contract, wage and tenure) and participants’ biographical and working profiles of CCRs (gender, age, educational attainment), on the others. However, the most interesting finding emerges by distinguishing different dimensions of job satisfaction (extrinsic and intrinsic-relational). In particular, the relationship between type of contract and job satisfaction is rather interesting. For non-permanent workers, in fact, the probability of being dissatisfied is decidedly greater if we consider the extrinsic dimension of job satisfaction. Instead, when the intrinsic-relational dimension is taking into account, atypical workers are no more dissatisfied than the permanent ones. Job insecurity and limited perspectives in terms of work alternatives, safeguards and rewards, seem to be the source of greatest dissatisfaction for Italian CCRs. This certainly does not surprise considering the Italian development model and its dualistic labour market, highly segmented between insiders and outsiders.     

Public school accountability,workplace culture,and teacher morale

Educational scholars claim that teacher morale has suffered from accountability pressures and constrained professionalism, but exactly what is most diminished by these pressures remains unclear. Drawing on recent theoretical work on public school organizational culture, we hypothesize that accountability pressures hurt teacher morale and increase the risk of turnover by undermining the professional culture of the school and by diminishing teacher cooperation and trust. We find support for this hypothesis in a national sample of teachers in 2011–12, and a follow-up survey from 2012–13. The analyses test whether a collective pedagogical teacher culture, comprised of professional culture and teacher collaboration, buffers the impact of these pressures that diminish teacher morale. Counter to past research, we find that a strong collective pedagogical teacher culture does not buffer teachers from the ill effects of negative workplace conditions in the form of accountability pressures. We also find that accountability pressures in the form of district dismissals are associated with a higher likelihood of teachers leaving their school, and this relationship is not mitigated by strong professional culture. We conclude that accountability pressures partly undermine goals of improving performance and equity in public schools by sowing seeds of teacher dissatisfaction and contributing to teacher turnover, thus thwarting student achievement in struggling schools.     

国际制裁的目的、条件、方式及其对中国参与国际制裁的启示

国际制裁作为发起主体实现政治目标的手段，旨在说服或迫使一个国家停止参与不被接受的行为，达到惩罚目标国行为、削弱目标国实力、宣传自身价值观或表明本国立场的目的。相比代价高昂的军事行动，国际制裁具有低成本的特点，成为冷战以来越来越多的国家和国际组织解决国际争端的工具。作为大国对外政策工具，实施国际制裁需要具备一定的条件，如双方的相互依存度、力量对比、利益权衡和国内外支持等。根据不同的制裁目的和条件，制裁国可以灵活选择多边制裁或单边制裁、复合制裁或单一制裁、全面制裁或目标制裁等制裁方式。中国作为一个举足轻重的大国，已具备利用国际制裁来维护国际正义和本国利益的能力，支持在联合国框架下参与国际制裁。在制裁参与中，中国需要根据国家利益及本国国情，建立和完善相关的制裁执行机制，合理选择制裁方式，使国际制裁更好地服务于国家利益。     

Public sector managers: the decision to leave or remain in a job

The public sector faces a grave problem as far as managerial retention as the result of the increasing number of retirements and of voluntary resignations. Despite the vital interest in managerial turnover in the public sector, research is scarce. This study, which increases our understanding of why public sector managers leave their positions, takes a qualitative and narrative research approach in examining voluntary turnover. Interviews were conducted with operations managers (in education, social care, and technical activities) at three Swedish municipalities. We identify a multitude of environment push and pull factors with a focus on administrative support, supervisory support and illegitimate tasks. The narratives of managerial turnover reveal the complexity of the decision to leave or remain in a job, containing a mixture of push and pull factors, negative feelings, unmet expectations and extraordinary events. Three possible HRD actions to decrease undesirable managerial turnover are identified: re-work organizational structures; re-model job characteristics; and re-examine managerial turnover decisions as a long and complex process. Our hope is that the findings are used for ultimately create healthy organizations.     

Elementary renewal theorems for widely dependent random variables with applications to precise large deviations

Abstract

On the basis of Wang and Cheng (J. Math. Anal. Appl. 384 (2011) 597–606), this paper further investigates elementary renewal theorems for counting processes generated by random walks with widely orthant dependent increments. The obtained results improve the corresponding ones of the above-mentioned paper mainly in the sense of weakening the moment conditions on the positive parts of the increments. Meanwhile, a revised version of strong law of large numbers for random walks with widely orthant dependent increments is established, which improves Theorem 1.4 of Wang and Cheng (2011 Wang, Y., and D. Cheng. 2011. Basic renewal theorems for a random walk with widely dependent increments and their applications. Journal of Mathematical Analysis and Applications 384 (2):597–606. doi:10.1016/j.jmaa.2011.06.010.[Crossref], [Web of Science ®] , [Google Scholar]) by enlarging the regions of dominating coefficients. Finally, by using the above results, some precise large deviation results for a nonstandard renewal risk model are established, in which the innovations are widely orthant dependent random variables with common heavy tails, and the inter-arrival times are also widely orthant dependent.     

La qualité de l'emploi en Amérique latine: théorie et faits

Traditionnellement, la littérature sur le développement consacrée aux marchés du travail d'Amérique latine s'est concentrée sur le nombre d'emplois et la productivité. Mais, étant donné la persistance d'une forte proportion d'emplois informels ou précaires, pour que l'analyse ait du sens, il faut aussi considérer des implications du statut professionnel sur la qualité de l'emploi. Partant d'observations faites ces dernières décennies, les auteurs concluent que la plupart des aspects de cette qualité – protection sociale comprise – dépendent de la signature d'un contrat écrit. Ce constat les conduit à formuler quelques suggestions pour stabiliser l'emploi formel et assurer un financement suffisant de la protection sociale.
