Newton-like phasor extremum seeking control with application to cooling data centers
No full textWe design a Newton-like phasor-based Extremum Seeking Control (ESC) aimed at multi-variable nonlinear control systems. We first augment the derivative estimator underlying the phasor approach to capture the Hessian of the plant index. Then we use these estimates to steer the system along a Newton-like direction. We assess the closed-loop stability of the proposed scheme and demonstrate its effectiveness in a data center cooling scenario.</p
Energy‐efficient operation of indirect adiabatic data center cooling systems via Newton‐like phasor extremum seeking control
No full textThis paper considers the problem of optimizing the operation of Indirect Adiabatic Cooling (IAC) systems with application to data centers. Optimal operation is achieved when the required cooling demand is satisfied at the minimum energy cost. For this purpose, we design a supervisory control system, where the higher layer determines the optimal set‐points for the local controllers by employing an Extremum Seeking Control (ESC) scheme. In particular, we consider a Newton‐like phasor ESC, which augments the derivative estimator underlying the phasor approach to capture also the Hessian of the plant index and then it uses these estimates to steer the system along a Newton‐like direction. The effectiveness of the considered approach is tested in simulation by exploiting a Matlab‐based simulation environment including an IAC system and a computer room.</p
Is microfinance the answer?: VISACA interventions in The Gambia
No full textThe primary goal of this exploratory study was to investigate how microfinance affects the lives of the rural men and women in The Gambia. Additionally, the study also investigated whether the institutional capacity of the Village Savings and Credit Associations (VISACAs) played any role in enhancing or inhibiting the microfinance intervention scheme. Using a mixed- methods approach, the study was conducted using several data collection tools. Questionnaires were completed by five national experts, and eight microfinance Technical Service Providers (TSPs) in the area of microfinance to gain a broad understanding of microfinance in the Gambia. Semi-structured interviews were conducted with a random sample of 120 microloan recipients and 50 VISACA employees. The questionnaires and interviews were augmented with existing secondary data, participant observations, and field notes. A combination of descriptive statistics, regression, and chi-square analysis was used to examine the quantitative data. Qualitative data was analyzed by pulling themes and making sense of the themes. The study found that participation in microfinance leads to an increase in individual and household income and savings. The ability to better provide for one’s family also increased. While a number of the recipients accumulated some assets, a considerable number reported that acquiring those assets resulted from their participation in the microfinance program. The results of the regression analysis suggest that there was no significant relationship between changes in income and savings (dependent variables) and the strength of the VISACA. Furthermore, chi-square results indicated no significant relations between women’s empowerment and the strength of the VISACA. The themes that emerged from the qualitative analysis, for the most part complement the statistical findings. The need to strengthen the VISACAs through capacity building emerged as a central issue that needs to be addressed to ensure long-term sustainability.Ph.

I molteplici livelli dell’interazione nella comunicazione terapeutica: teoria e ricerca di base
No full textA partire dal racconto dell’esperienza personale che l’ha portata a sviluppare il suo modello l’Autrice presenta i capisaldi della sua teoria del codice multiplo, integrata ed aggiornata con le più recenti acquisizioni provenienti dalle scienze cognitive e dal campo dei modelli psicoterapeutici. Vengono descritte le qualità che caratterizzano i tre principali livelli dell’elaborazione dell’informazione emotiva umana – sub-simbolico, simbolico non verbale, simbolico verbale – e la molteplicità dei codici modalità-specifici attraverso i quali viene esperita l’interazione con il mondo. All’interno di questa nuova teoria della mente vengono definiti concetti e processi clinici cruciali quali quello di schema dell’emozione, le sequenze interattive tipiche che portano alla loro formazione e alla loro riattivazione nella comunicazione terapeutica, i processi interattivi e soggettivi che portano alla persistenza degli schemi dell’emozione dolorosi o alla continua modificazione di quelli che creano benessere. Infine l’Autrice descrive il processo referenziale che connette i vari livelli dell’elaborazione dell’informazione emotiva sia nel contesto quotidiano sia durante la psicoterapia, dove si alternano circolarmente la fase dell’attivazione, della simbolizzazione e della riorganizzazione/riflessione. L’Autrice conclude mettendo in luce la natura eminentemente incarnata e relazionale di tale processo, come anche i suoi rischi e paradossi.Starting from a description of the personal experience that prompted her to develop her model the Author presents the cornerstones of her multiple code theory, revised and updated with the most recent findings from cognitive sciences and psychotherapeutic models field. The qualities characterizing the three main levels of the human emotional information processing – sub-symbolic, symbolic non-verbal, symbolic verbal – and the multiple modality specific codes through which is experienced the interaction with the world are described. Within this new theory of mind crucial clinical concepts and processes are defined as the emotion schemas, the typical interactive sequenc- es from which they emerge and their reactivation in the therapeutic communication, the interactive and internal processes that conduct to the persistence of the painful emotion sche- mas or to the continuous modification of those promoting the subject’s wellbeing. Finally, the Author describes the referential process that connects the various levels of emotional information processing in the everyday contexts as well as during psychotherapy, where circularly three typical phases follow one other – activation, symbolization and reorganization/reflection. The Author concludes by highlighting the eminently embodied and relational nature of this process, as well as its risks and paradoxes
Note del terapeuta e misure del processo referenziale. Un possibile "terzo analitico"
No full textViene proposta un’analisi delle note riportate dal terapeuta sul lavoro clinico con un paziente, condotta attraverso l’applicazione delle misure linguistiche computerizzate elaborate all’interno della teoria del codice multiplo. I risultati, in accordo con la letteratura, hanno evidenziato una forte relazione tra le qualità linguistiche degli appunti del terapeuta e l’efficacia del lavoro clinico. L’analisi linguistica delle note del terapeuta può quindi, oltre ad ampliare le possibilità della ricerca clinica, essere un utile supporto per comprendere e prevedere in una certa misura l’andamento del caso e il tipo di relazione che si instaura nella coppia durante il lavoro terapeutico. Il clinico che adotta questa metodologia nella propria prassi professionale può disporre di uno strumento di analisi che facilita la supervisione e la riflessione sul caso, divenendo così un “terzo analitico” che contribuisce a monitorare e potenziare il processo referenziale che lo connette con l’esperienza emozionale che sta vivendo e con il paziente.The Author presents an analysis of a therapist’s notes on the clinical work with a patient by means of Multiple Code Theory computerized linguistic measures. In accordance with literature the results show a strong connection between the linguistic properties of the therapist’s notes and the effectiveness of treatment. Thus, the linguistic analysis of the therapist’s notes not only expands the possibilities of clinical research, but also could be a useful support to understand and predict the evolution of a case and the type of relationship developed by the therapeutic couple. Clinicians that adopt this methodology in their professional practice have a useful tool facilitating supervision and reflection on the case. This tool can be considered as an “analytic third” monitoring and strengthening the referential process that connects therapists to their lived emotional experience and to patients

I molteplici livelli dell’interazione nella comunicazione terapeutica: applicazioni cliniche della teoria
No full textAttraverso la ripresa di alcuni passaggi salienti di quattro casi clinici l’Autrice fornisce una descrizione iconica e microanalitica del procedere delle tre fasi del processo referenziale – attivazione, simbolizzazione, riflessione – durante la seduta analitica. La fase finale dell’analisi di Katy, così come descritta da Bromberg, esemplifica la natura congiunta ed emotiva del processo di creazione di nuovi significati che avviene nelle tre fasi; le due psicoterapie senso-motorie, descritte da Ogden, mettono in risalto la natura eminentemente corporea, sensoriale e motoria degli schemi dell’emozione dissociati che è necessario ed utile attivare durante la terapia; infine il caso di Ann, descritto da Cornell, fornisce un esempio dell’imprescindibilità dell’attivazione nella relazione analitica dei vissuti corporei, sensoriali e motori che creano sofferenza nel paziente per poterli poi farli accedere al livello simbolico e con ciò favorire un cambiamento reale. A conclusione vengono evidenziati i molteplici ruoli che il linguaggio assume all’interno di ciascuna fase del processo referenziale.Reporting some salient passages of four clinical cases the Author provides an iconic and micro-analytical description of the proceeding of the three phases of the referential process – activation, symbolization, reflection – during the analytic session. The final stage of the analysis of Katy, as described by Bromberg, exemplifies the joint and emotional nature of the process creating new meanings in the three phases; the two sensorimotor psychotherapies, described by Ogden, highlight the nature inherently bodily, sensory and motoric of the dissociated emotion schemas that is necessary and useful to activate during the therapy; finally the case of Ann, described by Cornell, provides an example of the indispensability of the activation in the analytic relationship of the bodily, sensory and motoric experiences afflicting the patient to be able to connect them to the symbolic level and thereby to bring about a actual change. At the end are stressed the multiple roles taking the language in each phase of the process referential
Biomass and carbon forage by Atta laevigata (Hymenoptera: Formicidae) in eucaliptals in the cerrado
No full textEucalyptus plantations in Brazil have been growing in recent years, as they are raw materials for products of great global importance, such as cellulose, paper and energy. These plantations are also important for carbon storage, encouraging the market for carbon credits by companies and governments. However, wood production and carbon storage expectations can be compromised by insect pest herbivory, with emphasis on leaf-cutting ants. Many studies have addressed the role of these ants on wood production, but few have linked them to carbon foraging and its relationship to the climatic factors of the Cerrado biome, where most Brazilian eucalyptus is cultivated and the occurrence of Atta laevigata, one of the most economically important species for eucalyptus, predominates. Understanding this relationship is important to know the role of these herbivores in the accumulation of carbon in plants and soil and their contribution to the greenhouse effect. Therefore, the objective of this work was to evaluate how the temperature and relative humidity of the air influence the foraging of carbon biomass by Atta laevigata in eucalyptus in the Cerrado biome. The work was divided into three chapters. The first reviewed the role of leaf-cutting ants at each stage of the carbon cycle in the plant and soil. The second evaluated how the temperature and relative humidity of the air influence the foraging activity of A. laevigata in different seasons of the year in eucalyptus plantations. The third estimated the biomass and carbon foraged by leaf-cutting ants, depending on the temperature and air humidity in eucalyptus trees in the Cerrado. The results allowed to conclude that the foraging activity is predominantly daytime in three seasons, contrary to what is reported, being more intense in temperatures between 15 to 26°C and relative humidity between 66 to 80%. The accumulation of dry biomass and carbon varies throughout the year, with greater value in the summer and less in the spring. The annual amount of carbon foraged by a single active trail from a 72.87 m² Atta laevigata nest was 17 kg of carbon, corresponding to the amount of stored carbon of 6.96 trees per year.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)As plantações de eucalipto no Brasil têm se mantido crescente nos últimos anos, pois é matéria prima para produtos de grande relevância mundial, como celulose, papel e energia. Além desses produtos, tais plantações são importantes para a estocagem de carbono, fomentando o mercado de créditos de carbono por empresas e governos. No entanto, as expetativas de produção de madeira e estocagem de carbono podem ser comprometidas pela herbivoria de inseto-praga, com destaque para as formigas cortadeiras. Muitos estudos abordaram o papel da herbivoria dessas formigas sobre a produção de madeira, mas poucos os relacionaram com o forrageamento de carbono e sua relação com os fatores climáticos do bioma Cerrado, onde é cultivada a maioria dos eucaliptais brasileiros e predomina a de ocorrência de Atta laevigata; uma das espécies mais importantes economicamente para os eucaliptais. Entender essa relação é importante para conhecer o papel desses herbívoros na acumulação de carbono nas plantas e no solo e sua contribuição no efeito estufa. Portanto, o objetivo deste trabalho foi avaliar como a temperatura e umidade relativa do ar influenciam o forrageamento de biomassa carbono por Atta laevigata em eucaliptais no bioma Cerrado. O trabalho foi dividido em três capítulos. O primeiro revisou o papel das formigas cortadeiras em cada etapa do ciclo do carbono na planta e no solo. O segundo avaliou como a temperatura e umidade relativa do ar influenciam a atividade de forrageamento da A. laevigata em diferentes estações do ano em plantios de eucalipto. O terceiro estimou a biomassa e o carbono forrageados pelas formigas cortadeiras, em função da temperatura e umidade do ar em eucaliptais no Cerrado. Os resultados permitiram concluir que a atividade de forrageamento é predominantemente diurna em três estações do ano, ao contrário do que é relatado, sendo mais intensa em temperaturas entre 15 a 26°C e umidade relativa entre 66 a 80%. A acumulação de biomassa seca e de carbono varia ao longo do ano, com maior valor no verão e menor na primavera. A quantidade anual de carbono forrageado para uma única trilha ativa de um ninho de Atta laevigata de 72.87 m² foi de 17kg de carbono, correspondendo á quantidade de carbono estocado 6.96 árvores por ano
Collateral and Credit Supply
No full textThe author examines the role of collateral in an environment where lenders and borrowers possess identical information and similar beliefs about its future value. Using option-pricing techniques, he shows that a secured loan contract is equivalent to a regular bond and an embedded option to the borrower to default. He finds that the lender will not advance to the borrower a loan that exceeds the market value of the collateral, and that the supply of loans increases with a rise in the market value of the collateral. Increases in the volatility of the value of the collateral, interest rate, and dividend rate of the collateral independently depress the loan supply. The author also derives the cost of a third-party guarantee of a loan and an implied risk premium.Credit and credit aggregates; Economic models
GENDER-BASED VIOLENCE IN AMA ATTA AIDOO’S NO SWEETNESS HERE
No full textThe aim of this study is to offer a critical analysis of No Sweetness Here by Ama Atta Aidoo to identify forms of gender violence which is a violence intentionally perpetrated by husbands or male partners-people known to be intimate associates in the text. The feminist approach has been adopted as our theoretical framework. The text offers interesting representations of the complex ways in which female characters feature as gender abuse victims in situations where gender violence is prevalent. Descriptive analysis is the main method of data analysis in this study. The study revealed that the protagonist, Maami Ama suffered several forms of gender-based violence such as emotional, economic, marital, and social and discrimination in her matrimonial home. The author portrayed her as struggling against gender–based violence from her husband, her mother- in-law and sister-in-laws.
