Grass roots movements in relationships of cooperation and conflict between firms, communities, and government have an important role to stop a living city from disappearing. This chapter describes and analyzes the implications of the collective action used by grass roots movements in the defense of an old mining town, Cerro de San Pedro, of being disappeared due to the pollution of fresh watersheds by the operations of a mining company and the effects on the living city of San Luis Potosì, in the center of Mèxico.

The aim of this paper is to analyze relationships of cooperation and conflict between a mining company and the involved communities, focusing on the presence of the mining company (MSX) in Cerro de San Pedro, Mexico.
The paper focuses on the co‐operation and conflict between firms, communities, new social movements and the role of government.
The presence of the mining company has caused a severe social conflict among the inhabitants of San Pedro, Soledad y San Luis, alerting all who are concerned with historic heritage, cultural and environmental issues. At the center of the controversy is the cheap and efficient technology. Federal and state laws were violated. It is quite evident that there was a lack of sensitivity of foreign mining companies toward the consequences of their activities upon the communities and environment. This case also shows the lack of negotiation between firms, communities, new social movements and governments. Information about externalities and future costs of company activities is crucial but more crucial is formulation and implementation of more sensitive policies to avoid damage to the environment, biodiversity and health of the population. Governmental institutions must be aware that their decisions may affect the quality of life of present and future generations for the sake of a small increment in economic growth and large increase in private benefits of a small group of investors. More informed citizens tend to be more active protestors, such as the case of the students in San Luis. Contact between informed individuals of diverse groups and organizations helps to exchange experiences and create public opinion in favor of mobilization. Community participation and involvement in decision‐making of community development planning is quite limited by the lack of critical information. This fact is critical when the local government cannot provide the right information because there are other interests affecting the process.
The paper highlights the lack of sensitivity of foreign mining companies towards local communities.

In the twenty-first century, the family has been turning towards a greater plurality of training paths, situations, family and parental arrangements. However, despite changes in legislation, values, representations and practices, the word family remains inexorably associated with the heterosexual bi-parental model. This paper aims to contribute to the knowledge of the family dynamics of non-heterosexual people, mainly concerning the process of transition to parenting, in relation to family changes in Portuguese society. To do so this study aims to analyze four in-depth interviews1 with young adults, women and men who have a homoconjugality relationship and a project of parenting in mind.
Based on a qualitative methodology the study intends to discuss issues related to the challenge of heteronormativity, equality within the couple, projects and gender representations of parenthood and in particular what it means for the men and women interviewed, to be a father and to be a mother in a same sex couple and how they project themselves as fathers and mothers.
The study discusses all these issues always in relation to the biographical trajectories, the history and life as a couple and the structural and individual resources, such as school and professional qualifications. It also analyzes the main difficulties experienced in revealing their sexuality to the significant others and the difficulties / strategies they anticipate in relation to the parenting project.
The authors conclude that female interviewees show greater independence of a male figure in relation to their parental projects and anticipate less difficulty in their parental skills compared with the gay man interviewed.
To analyze the dynamics of parenting in same-sex couples, this study also points out to the need to construct a model of analysis capable of articulating structural factors, such as job insecurity and heteronormativity, biographies and individual resources and profiles of conjugal interactions.

The purpose of this paper is to highlight how data from marine protected area (MPA) surveys can be used to facilitate the development of systematic approaches to monitoring biodiversity within local government development plans and across marine bioregions.
The study focussed on coastal Barangays of the Municipality of San Luis, Aurora Philippines. A Participatory Coastal Resource Assessment (PCRA) was conducted to gather information on corals and reef fishery resources. Resultant Simpson’s biodiversity indices were calculated and compared to other MPA sites. Linkages to enhanced marine curriculum in a San Luis high school were evaluated by utilizing cultural consensus theory (CCT) on previously reported local student perception surveys as a further effort on defining pathways for localized transformation.
San Luis MPA biodiversity indices ranged from 0.56-0.8 on a scale of 0-1. This initial analysis demonstrates how local monitoring can be connected to resource assessment through biodiversity considerations and in developing local plans for site improvement linked to local economies. Results are used to demonstrate the potential for further development of an integrated approach to biodiversity monitoring across and between bioregions as a step forward in strengthening science for MPAs and biodiversity conservation for the Philippines.
The study could be used to pilot study strengthening of coastal resource management (CRM) at Municipal and Barangay levels and as well through application of CCT to the topics. The results will be used to reinforce the formulation of San Luis local development plans to better consider marine resource assessment.
This paper provides a new perspective on the use of quantitative measures of biodiversity to assist with local development plans. Projecting integrated biodiversity monitoring across and between bioregions is considered as a potential tool for facilitating climate change mitigation.

Russ Clark is a successful NAPA Auto Parts franchisee in Yuma County, Arizona. He sees opportunity in the neighboring Mexican city of San Luis Rıo Colorado. But crossing the border with an after-market auto parts store will require building relationships with others, lots of learning to overcome the significant barriers, and some savvy decision-making in addition to the usual evaluation of business opportunities. Clark must consider a location decision, product mix, human resource issues, and how to promote the new business in an uncertain and unfamiliar context. Clearly, his current American business model will require a great degree of adaptation to make the venture a success. This case was developed from extensive field interviews and shadowing Mr. Clark for a day. In addition, Mr. Clark and his store manager, Rigoberto made classroom presentations describing their experiences surrounding the case situation.

The impetus was to assess pluses and minuses of a national mandate with specific paratransit guidelines per “the” 1990 Americans with Disabilities Act (ADA) model. Two European countries were chosen to explore other ways to serve persons with disabilities, not driven by ADA.
This research compared mandates in each area (via a tri-lingual survey) both as related to ADA’s most common practices and the European model of “Persons with Reduced Mobility” (PMRs). After data collection, analysis compared and contrasted ADA and PMR schemes.
Even in California, differences were found among survey sites; for instance, the organization type and mix of services varied greatly, despite a national framework. In Europe, there were more similar approaches among regions where, without a national framework, there was flexible, regional decision-making. In Europe, the national focus is on more regular transit accessibility, maximizing transit use rather than special services.
Five recommendations resulted and apply most directly to California and equally for agencies with or without ADA. The strengths of the PMR approach are transferable to California and the trend among a few California partners to go beyond ADA, while only a local option, reinforces the strength of the PMR solution.
How to improve service and financial performance and enlarge the private sector role are put forward. Existing methods, whether Federal or California-driven, need revisiting to achieve true benefits of coordination.

The purpose of this paper is to present a new vision-based control method, which enables delta-type parallel robots to track and manipulate objects moving in arbitrary trajectories. This constitutes an enhanced variant of the linear camera model-camera space manipulation (LCM-CSM).
After obtaining the LCM-CSM view parameters, a moving target’s position and its velocity are estimated in camera space using Kalman filter. The robot is then commanded to reach the target. The proposed control strategy has been experimentally validated using a PARALLIX LKF-2040, an academic delta-type parallel platform and seven different target trajectories for which the positioning errors were recorded.
For objects that moved manually along a sawtooth, zigzag or increasing spiral trajectory with changing velocities, a maximum positioning error of 4.31 mm was found, whereas objects that moved on a conveyor belt at constant velocity ranging from 7 to 12 cm/s, average errors between 2.2-2.75 mm were obtained. For static objects, an average error of 1.48 mm was found. Without vision-based control, the experimental platform used has a static positioning accuracy of 3.17 mm.
The LCM-CSM method has a low computational cost and does not require calibration or computation of Jacobians. The new variant of LCM-CSM takes advantage of aforementioned characteristics and applies them to vision-based control of parallel robots interacting with moving objects.
A new variant of the LCM-CSM method, traditionally used only for static positioning of a robot’s end-effector, was applied to parallel robots enabling the manipulation of objects moving along unknown trajectories.

Brazil has been increasing its participation in the international trade market, mainly due to agricultural and forestry products, as in the case of soybeans and cellulose. This growth led to the expansion of the logistics infrastructure and its use. An important example of this trend is the port of São Luís, MA, in northern Brazil, which saw an increase in exports via rail (more than 200% growth in 6 years) and, consequently, an increase in the circulation of trains within its port complex.
This work proposes a mixed-integer linear programming model for the daily train scheduling problem at this port. All trains operated by VLI, a logistics company, are scheduled to minimize the departure times in order to improve the dwell time of freight train cars.
The railroad system in this Brazilian port consists of two classification yards, five terminals and a double-track railway for circulation. Different products such as grains, minerals, cellulose, and fuels are transported. The model also incorporates different operations at terminals and occupation restrictions due to maintenance and the physical flow of other third-party logistics companies. These features are modeled through a preprocessing step. In this phase, a series of auxiliary sets are defined to simplify constraints, circulation options are mapped, and the double-track is divided into segments based on the transit time with the objective to control track occupation.
This preprocess step also reduces the model complexity and, consequently, the computational time to solve it, as shown in the numerical tests using real-world operational data.
The main gains of the project were a reference train timetable for peak days, standardization of train crossing options, and a support tool for traffic adjustments with other rail operators.

Purpose – To examine how youth appropriate and resist elements of the developmental discourse as they construct and enforce dating norms.
Methodology – In 2007, we conducted participant observation at a middle school summer camp for youth in sixth, seventh, and eighth grades. Youth ranged in age from 11 to 17 years old.
Findings – Youth borrowed the idea of a normative sequence of behaviors arranged by age from the developmental discourse to establish a set of age-appropriate dating norms for all campers, regardless of chronological age. Youth enforced these norms by treating other dating actions as too young or too old. By tying this linear trajectory to social age instead of chronological age, youth creatively altered the apparently rigid developmental discourse and established dating norms which addressed their own values and concerns. Youth established dating norms and maximized opportunities for pleasurable, collective discussions about dating and romantic relationships. Although the developmental discourse influenced the norms in this peer culture, we argue that the small, heterogeneous composition of the camp facilitated youths' ability to appropriate, refashion, and resist the developmental discourse.
