Do Our Conservation Programs Work? A Spatially Explicit Estimate Of Avoided Forest Loss, Jordi Honey-Roses, Kathy Baylis, Maria Isabel Ramirez Dec 2010

Do Our Conservation Programs Work? A Spatially Explicit Estimate Of Avoided Forest Loss, Jordi Honey-Roses, Kathy Baylis, Maria Isabel Ramirez

Kathy Baylis

With the potential expansion of forest conservation programs spurred by climate-change agreements, there is a need to measure the extent to which such programs achieve their intended results. Conventional methods for evaluating conservation impact tend to be biased because they do not compare like areas nor do they account for spatial relations. We assess the effect of a conservation initiative that combined designation of protected areas with payments for environmental services to conserve overwintering habitat for the monarch butterfly (Danaus plexippus) in Mexico us a spatial-matching estimator which matches covariates among polygons and their neighbors, to. We measured avoided forest …

An Empathetic Psychological Perspective Of Police Deadly Force Training, Rodger E. Broome Dec 2010

An Empathetic Psychological Perspective Of Police Deadly Force Training, Rodger E. Broome

Rodger E. Broome

Police officers must be able to make an accurate appraisal of a lethal encounter and respond with appropriate force to mitigate the threat to their own lives and to the lives of others. Contemporary police deadly force training places the cadet in mock lethal encounters, which are designed to simulate those occurring in the real lives of law enforcement officers. This Reality Base Training (RBT) is designed to provide cadets with experiences that require their reactions to be within the law, policies and procedures, and ethics while undergoing a very stressful, emotional, and physically dynamic situation (Artwohl & Christensen, 1997; …


The First Two Years Of Independence In Kosovo: Links Between Political Systems And Business Enterprises, John R. Fisher, Baki Koleci, Muhaedin Bela Dec 2010

The First Two Years Of Independence In Kosovo: Links Between Political Systems And Business Enterprises, John R. Fisher, Baki Koleci, Muhaedin Bela

Dr. John R. Fisher

External conflict has impact on business and commerce and appears to be highly dependent on the political system. The connection between the political systems and business enterprises is more important in a new, developing country like Kosovo.


Measuring Performance In A Complex Problem Solving Task: Reliability And Validity Of The Tailorshop Simulation, Daniel Danner, Dirk Hagemann, Daniel V. Holt, Marieke Hager, Andrea Schankin, Sascha Wüstenberg, Joachim Funke Dec 2010

Measuring Performance In A Complex Problem Solving Task: Reliability And Validity Of The Tailorshop Simulation, Daniel Danner, Dirk Hagemann, Daniel V. Holt, Marieke Hager, Andrea Schankin, Sascha Wüstenberg, Joachim Funke

Joachim Funke

The Tailorshop simulation is a computer based complex problem solving task in which participants have to lead a fictional company for twelve months. The present study investigated if the performance in the Tailorshop simulation can be measured reliably and validly. The participants were 156 employees from different companies. Structural equation models were used to test tau-congeneric and tau-equivalent measurement models. The results indicate that the trends of the total capital between the second and the twelfth month are reliable measurements. Furthermore, this measure can predict real-life job performance ratings by superiors and is associated with the performance in another complex …


Beyond Iq. A Latent State-Trait Analysis Of General Intelligence, Dynamic Decision Making, And Implicit Learning, Daniel Danner, Dirk Hagemann, Andrea Schankin, Marieke Hager, Joachim Funke Dec 2010

Beyond Iq. A Latent State-Trait Analysis Of General Intelligence, Dynamic Decision Making, And Implicit Learning, Daniel Danner, Dirk Hagemann, Andrea Schankin, Marieke Hager, Joachim Funke

Joachim Funke

The present study investigated cognitive performance measures beyond IQ. In particular, we investigated the psychometric properties of dynamic decision making variables and implicit learning variables and their relation with general intelligence and professional success. N=173 employees from different companies and occupational groups completed two standard intelligence tests, two dynamic decision making tasks, and two implicit learning tasks at two measurement occasions. We used structural equation models to test latent-state-trait measurement models and the relation between constructs. The results suggest that dynamic decision making and implicit learning are substantially related with general intelligence. Furthermore, general intelligence is the best predictor for …


The Challenge Of Complexity For Cognitive Systems, Ute Schmid, Marco Ragni, Cleotilde Gonzalez, Joachim Funke Dec 2010

The Challenge Of Complexity For Cognitive Systems, Ute Schmid, Marco Ragni, Cleotilde Gonzalez, Joachim Funke

Joachim Funke

Complex cognition adresses research on (a) high-level cognitive processes – mainly problem solving, reasoning, and decision making – and their interaction with more basic processes such as perception, learning, motivation and emotion and (b) cognitive processes which take place in a complex, typically dynamic, environment. Our focus is on AI systems and cognitive models dealing with complexity and on psychological findings which can inspire or challenge cognitive systems research. In this overview we first motivate why we have to go beyond models for rather simple cognitive processes and reductionist experiments. Afterwards, we give a characterization of complexity from our perspective. …


Optimization As An Analysis Tool For Human Complex Decision Making, Sebastian Sager, Carola M. Barth, Holger Diedam, Michael Engelhart, Joachim Funke Dec 2010

Optimization As An Analysis Tool For Human Complex Decision Making, Sebastian Sager, Carola M. Barth, Holger Diedam, Michael Engelhart, Joachim Funke

Joachim Funke

We present a problem class of mixed-integer nonlinear programs (MINLPs) with nonconvex continuous relaxations which stem from economic test scenarios that are used in the analysis of human complex problem solving. In a round-based scenario participants hold an executive function. A posteriori a performance indicator is calculated and correlated to personal measures such as intelligence, working memory, or emotion regulation. Altogether, we investigate 2088 optimization problems that differ in size and initial conditions, based on real-world experimental data from 12 rounds of 174 participants. The goals are twofold. First, from the optimal solutions we gain additional insight into a complex …


The Plan-A-Day Approach To Measuring Planning Ability In Patients With Schizophrenia, Daniel V. Holt, Katlehn Rodewald, Mirjam Rentrop, Joachim Funke, Matthias Weisbrod, Stefan Kaiser Dec 2010

The Plan-A-Day Approach To Measuring Planning Ability In Patients With Schizophrenia, Daniel V. Holt, Katlehn Rodewald, Mirjam Rentrop, Joachim Funke, Matthias Weisbrod, Stefan Kaiser

Joachim Funke

Deficits in executive functioning are closely related to the level of everyday functioning in patients with schizophrenia. However, many existing neuropsychological measures are limited in their ability to predict functional outcome. To contribute to closing this gap, we developed a computer-based test of planning ability (“Plan-a-Day”), that requires participants to create daily activity schedules in a simulated work setting. Eighty patients diagnosed with schizophrenia were tested with Plan-a-Day and a battery of cognitive ability tests. Plan-a-Day showed satisfactory psychometric properties in terms of consistency, reliability and construct validity. Compared to other neuropsychological tests used in this study, it also demonstrated …

De La Búsqueda De Empleo Al Ascenso. Experiencias De Las Minorías Étnicas En Pekín, Reza Hasmath Dec 2010

De La Búsqueda De Empleo Al Ascenso. Experiencias De Las Minorías Étnicas En Pekín, Reza Hasmath

Reza Hasmath

Valiéndose de datos del censo y de entrevistas personales, el autor estudia las experiencias laborales de los trabajadores y solicitantes de empleo de Pekín pertenecientes a minorías étnicas. Los datos del mercado de trabajo indican que estas personas se hallan en desventaja respecto de la etnia han, que es la dominante, sobre todo en el acceso a los puestos más cualificados y mejor remunerados. Las comprobaciones del autor dejan entrever que ello puede achacarse a las lagunas de que adolece el orden laboral y que fomentan la dependencia de las redes sociales en este terreno.

Recherche D’Emploi, Embauche Et Promotions Le Vécu Des Minorités Ethniques Sur Le Marché Du Travail De Beijing, Reza Hasmath Dec 2010

Recherche D’Emploi, Embauche Et Promotions Le Vécu Des Minorités Ethniques Sur Le Marché Du Travail De Beijing, Reza Hasmath

Reza Hasmath

S'appuyant sur les microdonnées d'un recensement et les entretiens qu'il a menés auprès de travailleurs et d'employeurs, l'auteur examine la recherche d'emploi, l'embauche et la promotion des personnes issues des minorités ethniques à Beijing. Les données indiquent que les minorités ethniques sont défavorisées par rapport à l'ethnie dominante Han, notamment en ce qui concerne les emplois qualifiés offrant un salaire élevé. Les entretiens individuels menés par l'auteur montrent que ce handicap peut être dû aux failles de la structure institutionnelle qui favorisent le recours aux réseaux sociaux lors de la recherche d'emploi, de l'embauche et des promotions.

Determination Of Import Demand In Pakistan: The Role Of Expenditure Components, Muhammad Irfan Chani, Zahid Pervaiz, Amatul R. Chaudhary Dec 2010

Determination Of Import Demand In Pakistan: The Role Of Expenditure Components, Muhammad Irfan Chani, Zahid Pervaiz, Amatul R. Chaudhary

Muhammad Irfan Chani

The paper uses imperfect substitution approach to derive the aggregate import demand function on the basis of disaggregated expenditure components. This derived import demand function is then empirically tested for Pakistan by using co-integration and error correction mechanism. The empirical results show that elasticity of import demand with respect to different macro components of final expenditure is different. The import demand in Pakistan is affected positively and significantly by all expenditure components. The relative prices have negative but insignificant relationship with import demand in Pakistan. The findings indicate that use of aggregate expenditure variable in the aggregate import demand function …


Poverty, Inflation And Economic Growth: Empirical Evidence From Pakistan, Muhammad Irfan Chani, Zahid Pervaiz, Sajjad Ahmad Jan, Amjad Ali, Amatul R. Chaudhary Dec 2010

Poverty, Inflation And Economic Growth: Empirical Evidence From Pakistan, Muhammad Irfan Chani, Zahid Pervaiz, Sajjad Ahmad Jan, Amjad Ali, Amatul R. Chaudhary

Muhammad Irfan Chani

This study aims to investigate the role of economic growth and inflation in explaining the prevalence of poverty in Pakistan. ARDL bound testing approach to co-integration confirms the existence of long run relationship among the variables of poverty, economic growth, inflation, investment and trade openness over the period of 1972-2008. Empirical results show that economic growth and investment have negative and inflation has positive impact on poverty. The effect of trade openness on poverty is insignificant in this study. The short run analysis reveals that economic growth has negative and inflation has positive impact on poverty whereas the role of …

The purpose of this research is to investigate causal relationship between economic growth and major indicators of financial crisis -- inflation rate, interest rate and the volume of foreign debt-- in Pakistan. This study also highlights the stability of the relationship between indicators of financial crisis and economic growth. The annual time series data ranging from 1972 to 2010 is used for the analysis. Johansen's co-integration test is used to check the stability of long nm equilibrium relationship between the variables used in the study. The results indicate that is long nm stable equilibrium relationship between economic growth and the …


Gender Inequality And Economic Growth: A Time Series Analysis For Pakistan, Zahid Pervaiz, Muhammad Irfan Chani, Sajjad Ahmad Jan, Amatul R. Chaudhary Dec 2010

Gender Inequality And Economic Growth: A Time Series Analysis For Pakistan, Zahid Pervaiz, Muhammad Irfan Chani, Sajjad Ahmad Jan, Amatul R. Chaudhary

Muhammad Irfan Chani

This paper attempts to analyze the impact of gender inequality on economic growth of Pakistan. An annual time series data for the period of 1972-2009 has been used in this study. We have regressed growth rate of real gross domestic product (GDP) per capita on labour force growth, investment, trade openness and a composite index of gender inequality. The results reveal that labour force growth, investment and trade openness have statistically significant and positive impact whereas gender inequality has a significant and negative effect on economic growth of Pakistan.

Teenage Marriage And The Socioeconomic Status Of Hmong Women, Pa Der Vang Dec 2010

Teenage Marriage And The Socioeconomic Status Of Hmong Women, Pa Der Vang

Pa Der Vang, PhD, MSW, LICSW

The Hmong, who began migration to the United States in the latter half of the 1970's, represent a largely unstudied segment of the Asian-American population. Traditional practices such as teenage marriage were widely reported in the early years after migration began, but have been left relatively unexamined more recently. Explicit focus on Hmong women has been largely absent in recent research. This paper carmines the relationships between marriage patterns, education and earnings among Hmong women in the United States. Using results from a survey of 186 Hmong women, the results of this study indicate high rates of teenage marriage, as …


The Canonical Econophysics Approach To The Flash Crash Of May 6, 2010, Joao Mazzeu, Thiago Otuki, Sergio Da Silva Dec 2010

The Canonical Econophysics Approach To The Flash Crash Of May 6, 2010, Joao Mazzeu, Thiago Otuki, Sergio Da Silva

Sergio Da Silva

We carry out a statistical physics analysis of the flash crash of May 6, 2010 using data from the Dow Jones Industrial Average index sampled at a one-minute frequency from September 1, 2009 to May 31, 2010. We evaluate the hypothesis of a non-Gaussian Levy-stable distribution to model the data and pay particular attention to the distribution-tail behavior. We conclude that there is non-Gaussian scaling and thus that the flash crash cannot be considered an anomaly. From the study of tails, we find that the flash crash followed a power-law pattern outside the Levy regime, which was not the inverse …


Overconfidence And Excess Entry: A Comparison Between Students And Managers, A. Felipe Rodrigues, Newton Da Costa Jr, Sergio Da Silva Dec 2010

Overconfidence And Excess Entry: A Comparison Between Students And Managers, A. Felipe Rodrigues, Newton Da Costa Jr, Sergio Da Silva

Sergio Da Silva

Overconfidence can lead to excessive business entry. Here we replicate the pioneer experiment finding this nexus (Camerer and Lovallo 1999) and extend it in two major directions: (1) to consider managers as well as student subjects and (2) to explicitly take into account selected characteristics of the manager subjects. We find that managers are more prone to the nexus overconfidence-excess entry than students are. In particular, we find that left-handed, married, and emotionally aroused managers are more prone to excess entry.

A Log-Periodic Fit For The Flash Crash Of May 6, 2010, Raul Matsushita, Sergio Da Silva

Sergio Da Silva

We show that a two-harmonic log-periodic formula fits the high-frequency data from the Dow Jones Industrial Average index, which encompass the recent episode known as the “flash crash” of May 6, 2010.


Impacts Of China's Growth On The Brazilian Trade, Tatiana Ferrari, Milton Biage, Sergio Da Silva Dec 2010

Impacts Of China's Growth On The Brazilian Trade, Tatiana Ferrari, Milton Biage, Sergio Da Silva

Sergio Da Silva

We evaluate whether the presence of China in world trade is ultimately beneficial or whether it is a threat to Brazil. Using a gravitational model and a panel data method, we find that the Chinese exports to countries other than Brazil are not hurting the Brazilian exports, although the exports of Brazilian manufactured goods have been displaced by commodities as a result of its commerce with China.


Revisiting Staggered Wages To Consider Discounting, Patricia Bonini, Sergio Da Silva Dec 2010

Revisiting Staggered Wages To Consider Discounting, Patricia Bonini, Sergio Da Silva

Sergio Da Silva

In the literature of staggered wages, the discount factor is neglected in the workers’ loss function. Yet, discounting is to be viewed as an extra piece of microfoundation with implications for discretionary monetary policy. We revisit the issue and show that discounting in the model of staggered wages actually lowers the time-consistent steady inflation.
