Reference model for implementing ERP systems: an analytical innovation networks perspective

The process for implementing ERP systems is related with the identification of a large range of variables (organisational goals, business rules, business processes, actors, resources and specifics and unique concepts to support these variables). The main agents related to the implementation are the solution supplier, the customer company and the consulting service. If the implementation process is addressed as an organisational innovation, the question is: How to coordinate the ERP implementation resources from an innovation agents network? In order to answer this question, a reference model is proposed for the formation and management of an innovation agent’s network for ERP implementation. The research method is based on a multi-case study for identifying the requirements and to elaborate the reference model applying a modelling method the Enterprise Knowledge Development (EKD). As results, the reference model in an analytical perspective of innovation networks and their drivers, enables to identify, understand and support the process of implementing ERP systems under the EKD models they are: goals; business rules; business processes; actors and resources; concepts; technical components and requirements.     

Routing in a queueing system with two heterogeneous servers in speed and in quality of resolution

Heterogeneous servers, in manufacturing and service systems, may have different speeds and different quality levels for the provided service or good For a two-server queueing model, we formulate the job routing problem for minimizing the stationary weighted sum of the expected time spent in the system and the number of unsatisfied customers per time unit. Using a Markov decision process approach, we prove that the optimal routing policy of jobs to service is a threshold policy that depends on the queue length. When the number of waiting jobs in the queue is below a certain threshold, only one server should work and the other one remains idle. At or above this threshold, both servers should serve jobs. This is an extension of the known result where only the heterogeneity in speed is considered.     

Using an Initial Clinical Interview to Assess the Coparenting Relationship: Preliminary Examples From the Supporting Father Involvement Program

The current study uses an initial intake interview as an assessment tool in the Supporting Father Involvement (SFI) intervention and considers it from a family systems theoretical perspective. SFI includes a 32-hour group for parents with young children that aims to reduce child abuse and promote family well-being through a curriculum focused on enhancing positive father involvement and coparenting. For this study, the initial clinical interview assessed partners’ synchronies and dissonance in parenting, coparenting, and relationship satisfaction domains. Using thematic analysis, we qualitatively analyzed interviews with 15 committed, heterosexual couples, exploring themes that correspond with higher versus lower couple satisfaction measured by the Quality of Marital Satisfaction Index. Results showed a strong concordance between partners’ satisfaction scores, with fathers less satisfied than mothers. Thematic differences between higher and lower satisfaction parents centered on approach to discipline, coparenting communication, and quality of support systems. The importance of father involvement and fathers as “learning” parents and coparents were recurring themes for mothers and fathers, especially among higher satisfaction couples. Higher substance abuse and employment/financial stress were indicative of lower satisfaction couples. Discussion reflects on the utility of an initial clinical interview as an assessment and intervention planning tool and future directions for research.

意识形态、非正式制度与凉山彝区精准扶贫

意识形态作为非正式制度的核心,以及其具有的“地方性知识”特征,对精准扶贫的推行和取得的绩效产生了极大的影 响。从意识形态是否与现行的正式制度取得内在一致性,继而对社会经济活动产生正面或负面影响的思路出发,基于交易费 用的视角分析了意识形态如何对精准扶贫产生影响,并进一步揭示了意识形态在凉山彝区精准扶贫中产生消极作用的机理。 认为加强教育事业的发展,提高民众的认知能力和培养正确的价值观;以包容性发展的理念对当地元素进行取舍,形成大格局 信念共享的氛围,是减小意识形态与扶贫政策制度“摩擦力”的最好的途径。     

Pension Reforms,Working Patterns and Gender Pension Gaps in Europe

European pension reforms are dominated by the principles of privatization and individualization. Privatizing and individualizing pension entitlements call for a redefinition of the responsibilities of states and individuals. Moreover, statutorily introducing individualization calls for equal opportunities to be guaranteed. However, the implementation of equal opportunities is a long way off because pension‐determining factors are still subject to gender distinctions, among other things. Gender distinction is inherent in life courses as well as in welfare arrangements. Welfare arrangements determine the legitimate reasons for gaining pension rights, how the measures of different entitlements are interrelated and which factors hamper a person's ability to fulfil the pension norm. This article analyses the link between welfare arrangements and women's life courses for a better understanding of the gendered norms of pension entitlements by focusing on gendered wages and life expectancies, gendered working patterns, and the connection between care and pensions.     

Habitat fragmentation and conservation strategies for a rare forest habitat in the Florida Keys archipelago

Habitat loss and fragmentation are principal causes for population declines and the loss of biodiversity across the globe. In the United States, tropical hardwood hammock is a threatened forest ecosystem that occurs only in extreme south Florida, primarily on the Florida Keys archipelago. This rare forest type is characterized by high plant diversity that is strongly influenced by tropical, mast-producing trees and shrubs of West Indian origin. Tropical hardwood hammocks in the Florida Keys provide important habitat for resident and migratory birds, particularly Neotropical species that rely on suitable stopover habitat during migration. The Florida Keys are under intense development pressure, particularly in higher elevation sites where tropical hardwood hammock occurs. With exception of a survey completed during 1991 in the Upper Keys, information regarding habitat loss and current coverage, conservation status, and how best to conserve remaining patches of this rare forest habitat are lacking. We used a Geographic Information Systems approach to assess the extent of loss and fragmentation of tropical hardwood hammock in the upper Keys during 1991–2004, quantify area and number of hammock patches under private ownership and in conservation status throughout the Florida Keys as of 2004, and evaluate strategies to most effectively conserve large blocks of remaining tropical hardwood hammock. Total remaining hammock habitat throughout the Keys encompassed 3,712 ha and hammock habitat declined by 31% in the upper Keys during 1991–2004. Hammock habitat in the upper Keys encompassed 1,962 ha among 124 habitat patches (median = 1.5 ha, range = 0.1–205.7 ha), of which 1,066 ha (54%) were under conservation status. Hammock habitat in the lower Keys encompassed 1,750 ha among 102 patches (median = 4.4 ha, range = 0.3–96.3 ha), of which 1,283 ha (73%) were protected under conservation status. Approximately 37% of total remaining hammock habitat remained unprotected. However, our analyses revealed that many unprotected areas >20 ha were contiguous with protected hammocks. Safeguarding 22 partially protected patches >20 ha (17% of remaining patches) would protect an additional 750 ha of hammock habitat, which represents 55% of all remaining unprotected hammock habitat in the Keys, and would increase the mean patch size of these larger forest patches from 55 to 89 ha. Consequently, strategically focusing conservation efforts on remaining forest patches of tropical hardwood hammock >20 ha in size and contiguous to existing protected areas represents the most effective use of conservation dollars and would provide greater ecological benefits than conservation of small patches of highly fragmented habitat.     

An Integrated Approach to Managing Change

Complex systems often involve a huge number of variables whose interdependence must be taken into account. This makes the adoption of an integrated approach essential for the proper management of a wide range of aspects related to human life, from social matters to the environment. In particular, this paper takes into consideration three different experiences in which the use of an integrated approach represented the most effective response for managing the evolving realities we took into consideration. We focused on the issue of land management, with particular attention to the problem of monoculture in Brazil. Then we analyzed the attempted cooperation between the States of the Aral Sea area for efficient water management of the basin and, finally, we dealt with the matter of energy efficiency and how the production of home integrated systems could lead to a better rationalization of energy consumption in the near future.
