Abstract: Choosing between Less Than Truckload (LTL) and Full Truckload (FTL) is based on a multicriteria decision because it takes into account aspects such as costs and operational efficiency in transportation, handling and stock of goods. The aim of this article is to provide a detailed analysis of the criteria that comprise the LTL and FTL transport decision using a multicriteria methodology that considers decision makers´ preferences. The SMARTS method was applied in a telecommunications company that outsources its logistics operation. Results show that the main criteria for choosing LTL shipment are related to the relationship with the customer and the efficiency in the delivery of the freight (reliability of the delivery time). On the other hand, choosing FTL transport requires a high weight given to the criteria regarding benefits and cost of transit inventory. The contribution of the research is to provide a structured and flexible analysis to choose the types of shipment (FTL and FLT) when taking into account the risk aversion of decision makers using a non-optimal approach, but with approximate solutions encompassing several qualitative and quantitative criteria in this choice.

El objetivo del estudio consiste en aportar el conocimiento de los efectos generados por la actividad deportiva y la recreación en alta montaña, para fortalecer la gestión y la disminución de los impactos indeseables. El método ha consistido en la aplicación de una herramienta cualitativa y una cuantitativa: una encuesta a los actores relevantes dentro del mundo actividades recreativas de alta montaña y una adaptación de la Matriz de Leopold en senderos, campamentos y cumbres de dos sectores de práctica del deporte de alta montaña en la zona central de Chile; la revisión bibliográfica permite comprender, por otra parte, el fenómeno y destacar las iniciativas de las federaciones internacionales de actividades deportivas de montaña para la gestión ambiental. Llama la atención, como conclusión de la encuesta, la percepción del deporte de alta montaña como una actividad inocua que genera impactos despreciables y, por otra parte, destaca en los resultados de la Matriz de Leopold la concentración de desperdicios, los efectos de las tiendas de campaña y los baños improvisados, afectando principalmente a las fuentes de agua y al suelo. Lo que conlleva una situación donde los tomadores de decisión no son conscientes de los efectos y, por lo tanto, no están tomando las medidas adecuadas para su control.Abstract. The objective of the study is to provide knowledge about the effects generated by sports and recreation in high altitude mountains, to strengthen their management and decrease their undesirable impacts. The method consisted in the application of qualitative and quantitative tools: a survey to stakeholders, and an adaptation of the Leopold Matrix on trails, camps and summits in two areas for high altitude sport in the central region of Chile; on the other hand, bibliographic review allows to understand this phenomenon, and highlight the initiatives of international federations of mountain sports for better environmental management. As a conclusion of the survey, a surprising finding is that high mountain sports are perceived as innocuous activities that generate negligible impacts; on the other hand, concentration of waste, and effects of tents and improvised toilets stand out as main results from the Leopold Matrix, mainly affecting water sources and soil. This demonstrates that decision makers are not aware of the effects of mountain sports and, therefore, they are not taking appropriate measures to control them.

Abstract This article clarifies the ongoing confusion in doctrine and practice about both the actual and optimal interaction between international counterterrorism law (CTL) and international humanitarian law (IHL) in armed conflict. It discusses the advantages and disadvantages of the co-application of CTL with IHL, before considering a variety of techniques for mutually accommodating the interests of both regimes, particularly through partial exclusion clauses in counterterrorism instruments or laws. It concludes by identifying the optimal approach to the relationship between CTL and IHL, which recognizes the legitimate interests of both fields of law while minimizing the adverse impacts of each on the other.

People’s risky decisions can be highly influenced by the social context in which they take place. Across three experiments we investigated the influence of three social factors upon participants’ decisions: the recipient of the decision-making outcome (self, other, or joint), the nature of the relationship with the other agent (friend, stranger, or teammate), and the type of information that participants received about others’ preferences: none at all, information about how previous participants had decided, or information about a partner’s preference. We found that participants’ decisions about risk did not differ according to whether the outcome at stake was their own, another agent’s, or a joint outcome, nor according to the type of information available. Participants were, however, willing to adjust their preferences for risky options in light of social information.

A qualitative and quantitative analysis of the environmental damages occurrences was conducted through the lawful documents established for charging at the State Prosecution Service of São Carlos city, State of São Paulo, during 1991 - 2000, to understand the relationship between environmental problems and the current development actions. The environmental damage identified were grouped into nine classes, where deforestation was prevailing in each year along the period of study. Of the total number of deforestation occurrences, 180 was related to areas smaller than 5 ha. It corresponded to 110.35 ha of the total deforested area. The other 37 were associated with areas higher than 5 ha, equivalent to 1,013.27 ha. The registers of environmental damages in the period in a rough estimate, corresponded to a mediam loss of 5.91 ± 4.14 ha/occurrence and of 112.36 ± 91.73 ha/year of deforested area.

Background: The relationship between suicidal thinking and adolescent dating violence has not been previously explored in a sample of adolescent abortion patients. Aims: This paper highlights a study where the relationship between dating violence and severity of suicidal thinking was examined in a sample of 120 young women ages 14–21 seeking to terminate an unintended pregnancy. Methods: The Multidimensional Adolescent Assessment Scale and the Conflict in Adolescent Relationships Scale was used to gather information about psychosocial problems and dating violence so that the relationship between the two problems could be examined, while controlling for the other psychosocial problems. Results: The results suggest that dating violence was related to severity of suicidal thinking, and that the magnitude of this relationship was moderated by the severity of problems with aggression. Conclusions: Specifically, as the severity of participant’s general problems with aggression increased, the magnitude of the relationship between dating violence and severity of suicidal thinking increased. Limitations of the study and implications for practice are discussed.

When people are told that their negative memories are worse than other people’s, do they later remember those events differently? We asked participants to recall a recent negative memory then, 24 h later, we gave some participants feedback about the emotional impact of their event – stating it was more or less negative compared to other people’s experiences. One week later, participants recalled the event again. We predicted that if feedback affected how participants remembered their negative experiences, their ratings of the memory’s characteristics should change over time. That is, when participants are told that their negative event is extremely negative, their memories should be more vivid, recollected strongly, and remembered from a personal perspective, compared to participants in the other conditions. Our results provide support for this hypothesis. We suggest that external feedback might be a potential mechanism in the relationship between negative memories and psychological well-being.

SummaryThe relationship between haematocrit and cardiovascular risk factors, particularly blood pressure and blood lipids, has been examined in detail in a large prospective study of 7735 middle-aged men drawn from general practices in 24 British towns. The analyses are restricted to the 5494 men free of any evidence of ischaemic heart disease at screening.Smoking, body mass index, physical activity, alcohol intake and lung function (FEV1) were factors strongly associated with haematocrit levels independent of each other. Age showed a significant but small independent association with haematocrit. Non-manual workers had slightly higher haematocrit levels than manual workers; this difference increased considerably and became significant after adjustment for the other risk factors. Diabetics showed significantly lower levels of haematocrit than non-diabetics. In the univariate analysis, haematocrit was significantly associated with total serum protein (r = 0*18), cholesterol (r = 0.16), triglyceride (r = 0.15), diastolic blood pressure (r = 0.17) and heart rate (r = 0.14); all at p <0.0001. A weaker but significant association was seen with systolic blood pressure (r = 0.09, p <0.001). These relationships remained significant even after adjustment for age, smoking, body mass index, physical activity, alcohol intake, lung function, presence of diabetes, social class and for each of the other biological variables; the relationship with systolic blood pressure was considerably weakened. No association was seen with blood glucose and HDL-cholesterol. This study has shown significant associations between several lifestyle characteristics and the haematocrit and supports the findings of a significant relationship between the haematocrit and blood lipids and blood pressure. It emphasises the role of the haematocrit in assessing the risk of ischaemic heart disease and stroke in individuals, and the need to take haematocrit levels into account in determining the importance of other cardiovascular risk factors.

The review outlines the connection between E. Reinert’s book and the tradition of structural analysis. The latter allows for the heterogeneity of industries and sectors of the economy, as well as for the effects of increasing and decreasing returns. Unlike the static theory of international trade inherited from the Ricardian analysis of comparative advantage, this approach helps identify the relationship between trade, production, income and population growth. Reinert rehabilitates the “other canon” of economic theory associated with the mercantilist tradition, F. Liszt and the German historical school, as well as a reconside ration of A. Marshall’s analysis of increasing returns. Empirical illustrations given in the book reveal clear parallels with the path of Russian socio-economic development in the last twenty years.

Is it possible to transform stone into a technological and innovative device? The meeting with one of the main stone transformers in Europe produced the intention of a disruptive operation that could affect the strategy of the whole company. A contagious singularity. By intertwining LEAN methodologies and the human-centric approach of design thinking, we mapped the value creation in the company activating a dialogue with the workers and the management, listening to people, asking for ambitions, discovering problems and the potential of production. This qualitative and quantitative analysis conducted with a multidisciplinary approach by designers, architects and marketing strategists allowed us to define a new method. We used it to design a platform that could let all the players express their potential to the maximum. This is how the group's research laboratory was born, with the aim of promoting the relationship between humans and stone through product innovation. With this goal, we coordinated the new team, developing technologies that would allow creating a more direct relationship between man and surface, making the stone reactive. The result was the first responsive kitchen ever.
