Influence activity and the organization of research and development

The organizational design of research and development conditions theincentives of the researchers of the research project. In particular,the organizational form determines the allocation of effort of theresearcher between time spent on research and time spent lobbying management. Researchers prefer to spend their time on research. However,the researchers only get utility from performing research if theproject is approved for its full duration. Spending time lobbyingmanagement for the continuation of the researcher s project increasesthe probability that the management observes a favorable signal aboutthe project. Organizing a research joint venture increases theflexibility of the organizational form with respect to the continuationdecision. For low correlation between the signals of the partners aboutthe expected profitability of the project, we find that the organizationof a research joint venture reduces influence activity by the researchersand increases expected profits of the partners. For high correlationbetween the signals, internal research projects lower influence activityby the researchers. We try to relate the correlation of the partnerssignals to the characteristics of basic research versus more appliedresearch projects, and find that the model is consistent with theobservation that research joint ventures seem involved in more basicresearch projects compared to internal R&D departments, whichconcentrate on more applied research.

Building an honest microfinance organization: Embezzlement and the optimality of rigid repayment schedules and joint liability

We consider the agency problem of a staff member managing microfinancing programs, who can abuse his discretion to embezzle borrowers' repayments. The fact that most borrowers of microfinancing programs are illiterate and live in rural areas where transportation costs are very high make staff's embezzlement particularly relevant as is documented by Mknelly and Kevane (2002). We study the trade-off between the optimal rigid lending contract and the optimal discretionary one and find that a rigid contract is optimal when the audit cost is larger than gains from insurance. Our analysis explains rigid repayment schedules used by the Grameen bank as an optimal response to the bank staff's agency problem. Joint liability reduces borrowers' burden of respecting the rigid repayment schedules by providing them with partial insurance. However, the same insurance can be provided byborrowers themselves under individual liability through a side-contract.

Corporate criminal law and organization incentives: A managerial perspective

Corporate criminal liability puts a serious challenge to the economictheory of enforcement. Are corporate crimes different from other crimes?Are these crimes best deterred by punishing individuals, punishing corporations, or both? What is optimal structure of sanctions? Shouldcorporate liability be criminal or civil? This paper has two majorcontributions to the literature. First, it provides a common analyticalframework to most results presented and largely discussed in the field.In second place, by making use of the framework, we provide new insightsinto how corporations should be punished for the offenses committed bytheir employees.

Optimal law enforcement and criminal organization

In this paper, we take an organizational view of organized crime. In particular, we study the organizational consequences of product illegality attending at the following characteristics: (i) contracts are not enforceable in court, (ii) all participants are subject to the risk of being punished, (iii) employees present a major threat to the entrepreneur having the most detailed knowledge concerning participation, (iv) separation between ownership and management is difficult because record-keeping and auditing augments criminal evidence.

El desplegament curricular de les competències bàsiques. Una proposta real d’intervenció

Les competències bàsiques han entrat a formar part dels currículums del país per donar resposta a les finalitats educatives que s'han descrit en l'àmbit internacional per definir les capacitats i els sabers que s'han d'haver adquirit al final de l'educació secundària obligatòria. A més dels tradicionals continguts relacionats amb les disciplines del saber, els canvis socials i culturals que estem vivim, les noves relacions personals i la complexitat en l'àmbit laboral han provocat que el currículum inclogui altres continguts relacionats amb la formació integral de la persona mitjançant les competències metadisciplinàries. El fet d'introduir les competències bàsiques en un currículum organitzat per àrees i amb una descripció quasi nul·la dels objectius i continguts de cada competència n'ha dificultat molt la comprensió i la posada en pràctica. Actuar de manera competent vol dir saber resoldre amb èxit un problema o una qüestió de la realitat a partir de la mobilització de diferents tipus de saber que s'ajustin a la selecció d'un esquema per resoldre'ls. La proposta presentada del desplegament curricular de les competències és una eina que aporta tres avantatges. Primerament, permet seqüenciar i garantir el treball de totes les competències des de totes les àrees. En segon lloc, permet incorporar continguts metodològics competencials dins de les àrees disciplinàries. En tercer lloc, facilita que es donin les condicions necessàries per ensenyar i aprendre les competències a través de la creació de l'àmbit comú.

Las Competencias profesionales de los educadores sociales como punto de partida para el diseño curricular de la formación universitaria. Un estudio mediante el método Delphi

En estos últimos años, la universidad española ha estado inmersa en un proceso de transformación de las titulaciones universitarias como consecuencia de la adaptación al espacio europeo de educación superior. Esta transformación se concreta en un cambio de estructura de los ciclos universitarios a la vez que supone una modificación del modelo pedagógico: de un modelo centrado en la enseñanza se pasa a un modelo centrado en el aprendizaje del estudiante. Los planes de estudio de las titulaciones deben estructurarse partiendo de las competencias profesionales que se atribuyen a una determinada profesión. Por ello, la identificación correcta de dichas competencias se convierte en un elemento esencial para el diseño de los títulos. En este artículo presentamos el proceso seguido en la Universidad de Girona (España) para identificar las competencias profesionales de los educadores sociales. Una parte de dicho proceso fue la realización de un estudio en el que, mediante el método Delphi, un panel de expertos valoró y llegó a un consenso sobre cuáles son las competencias profesionales que los educadores sociales en ejercicio desarrollan. El listado ordenado de las competencias de los educadores sociales sirvió como punto de partida para la elaboración del plan de estudios de Educación social de dicha universidad. El propósito del artículo es explicar el proceso seguido y exponer las ventajas de esta información como referente para el diseño de las nuevas titulaciones universitarias

Self-organization mechanisms for the formation on nearshore crescentic and transverse sand bars

The formation and development of transverse and crescentic sand bars in the coastal marine environment has been investigated by means of a nonlinear numerical model based on the shallow-water equations and on a simpli ed sediment transport parameterization. By assuming normally approaching waves and a saturated surf zone, rhythmic patterns develop from a planar slope where random perturbations of small amplitude have been superimposed. Two types of bedforms appear: one is a crescentic bar pattern centred around the breakpoint and the other, herein modelled for the rst time, is a transverse bar pattern. The feedback mechanism related to the formation and development of the patterns can be explained by coupling the water and sediment conservation equations. Basically, the waves stir up the sediment and keep it in suspension with a certain cross-shore distribution of depth-averaged concentration. Then, a current flowing with (against) the gradient of sediment concentration produces erosion (deposition). It is shown that inside the surf zone, these currents may occur due to the wave refraction and to the redistribution of wave breaking produced by the growing bedforms. Numerical simulations have been performed in order to understand the sensitivity of the pattern formation to the parameterization and to relate the hydro-morphodynamic input conditions to which of the patterns develops. It is suggested that crescentic bar growth would be favoured by high-energy conditions and ne sediment while transverse bars would grow for milder waves and coarser sediment. In intermediate conditions mixed patterns may occur.

Deciphering the global organization of clustering in real complex networks

We uncover the global organization of clustering in real complex networks. To this end, we ask whether triangles in real networks organize as in maximally random graphs with given degree and clustering distributions, or as in maximally ordered graph models where triangles are forced into modules. The answer comes by way of exploring m-core landscapes, where the m-core is defined, akin to the k-core, as the maximal subgraph with edges participating in at least m triangles. This property defines a set of nested subgraphs that, contrarily to k-cores, is able to distinguish between hierarchical and modular architectures. We find that the clustering organization in real networks is neither completely random nor ordered although, surprisingly, it is more random than modular. This supports the idea that the structure of real networks may in fact be the outcome of self-organized processes based on local optimization rules, in contrast to global optimization principles.

The complex organization of human cognitive domains and their heritability: a systematic review

Una revisión sistemática de la organización compleja de los dominios cognitivos humanos y su heredabilidad. Antecedentes: se ha propuesto que la estructura de la cognición humana respondería a un sistema jerárquico, donde las secuencias propias a una acción se organizarían desde sub-unidades de análisis hasta funciones de nivel superior relativamente complejas. Esta estructura organizacional estaría reflejada en las representaciones neurales que subyacen al comportamiento humano, así como también en sus sustratos genéticos. El objetivo del presente estudio fue explorar la posible organización jerárquica de las influencias genéticas subyacentes a los dominios cognitivos humanos. Método: se revisaron treinta y cuatro estudios de la heredabilidad de la cognición en muestras de la población general, que incluyeron medidas de inteligencia, habilidades verbales y manipulativas, memoria, memoria de trabajo y velocidad de procesamiento. Resultados: diversos dominios cognitivos mostraron distintas proporciones de influencias genéticas, con las mayores estimaciones de heredabilidad halladas para las funciones cognitivas de nivel superior y las menores estimaciones para las funciones de orden medio o inferior. Conclusiones: tomando como referencia los conocimientos actuales acerca del neurodesarrollo humano, las contribuciones genéticas de las habilidades cognitivas parecen organizarse paralelamente al crecimiento ontogénico del cerebro. Se discuten estos resultados en relación a la interacción entre el control genético de las funciones cognitivas y sus influencias ambientales.

Work Organization Practices for Lean Production: A Study in Spanish and Brazilian Manufacturers

This work aims to discuss particular work organization practices in human resources reported as successful by companies adopting lean production principles, and investigate them through real examples observed on manufacturing plants in Spain and Brazil. A set of work organization practices was previously established by one of the authors, through interviews with practitioners of lean production and review of the literature. A series of visits and informal interviews at Spanish and Brazilian automotive parts manufacturers that follow lean production were conducted to verify that the set of policies are indeed practiced.
