ESTUDO DA EFICÁCIA ADAPTATIVA DE HERDEIROS DE EMPRESA FAMILIAR

O presente trabalho visa estudar a eficácia adaptativa dos herdeiros de empresa familiar, segundo a teoria da adaptação de Ryad Simon. Os objetivos foram: 1. investigar a eficácia adaptativa dos herdeiros de empresa familiar; 2. descrever aspectos da dinâmica adaptativa dos herdeiros; 3. descrever aspectos da dinâmica familiar internalizada pelos herdeiros de cada família; 4. investigar as repercussões obtidas pela análise da eficácia adaptativa de cada herdeiro no contexto da empresa familiar. O método utilizado foi clínico e a técnica, a entrevista clínica preventiva. Foram entrevistados sete herdeiros de duas diferentes empresas familiar, todos os herdeiros atuam profissionalmente nelas. Os dados das entrevistas foram avaliados clinicamente por meio da Escala Diagnóstica Adaptativa Operacionalizada (EDAO), e análise dos fatores, segundo Teoria da Evolução da Adaptação, de Ryad Simon. Os resultados encontrados foram: 72% (5 herdeiros) encontraram-se classificados no grupo 4 Adaptação Ineficaz Severa, 14% (1 herdeiro) no grupo 5 Adaptação Ineficaz Grave, e 14% (1herdeiro) no grupo 3 Adaptação Ineficaz Moderada em CRISE. Na análise destes resultados verificou-se a importância central do setor Afetivo-Relacional, 100% dos herdeiros foram classificados com respostas pouquíssimo adequadas, e o que mesclou as diferentes classificações, descritas acima, foi no setor Produtividade. Frente a este diagnóstico percebemos a importância das relações com a figura paterna, presente tanto no lar como na empresa. Na análise dos herdeiros e da dinâmica das duas famílias concluímos que quando a figura paterna comporta-se de forma onipotente e insubstituível, não permite que os filhos cresçam e busquem satisfação no que produzem. Diferente de quando este pai consegue colocar limites, mas gradativamente delega responsabilidades aos filhos, demonstrando confiar neles. Esta postura facilita o encontro da satisfação na área produtiva. Neste estudo ficou evidente que a dinâmica familiar estende-se até a empresarial, desta forma em uma das famílias, cujo pai foi capaz de delegar aos filhos o poder na empresa, a dinâmica na empresa parece ser saudável, permeada por impulsos construtivos. Enquanto a outra, cujo pai mantém o poder na empresa, parece estar muito doente, predominando os impulsos destrutivos na família com repercussão, também, na empresa.

ESTUDO DA EFICÁCIA ADAPTATIVA DE ESTUDANTES DE CURSO DE PSICOLOGIA E INDICAÇÃO TERAPÊUTICA COMO MEDIDA PREVENTIVA

O trabalho emocionalmente desgastante dos profissionais das áreas de saúde implica não só a necessidade de uma habilitação acadêmica, mas, acima de tudo, uma adaptação, um equilíbrio emocional satisfatório, premissa básica para um serviço eficaz à saúde da população. Preocupando-se com o futuro profissional de Psicologia, esta pesquisa teve por finalidade verificar o grau de eficácia adaptativa de alunos do curso de Psicologia da Universidade Metodista de São Paulo, São Bernardo do Campo SP e, quando necessário, fazer-lhes indicação terapêutica. Este trabalho foi desenvolvido com a utilização da EDAO (Escala Diagnóstica Adaptativa Operacionalizada). Durante os anos de 1999 e 2000, foram feitas entrevistas diagnósticas individuais no NEPAP (Núcleo de Estudos, Pesquisa e Atendimento Psicológico), da UMESP, em 10% dos alunos do curso de Psicologia, dos períodos matutino e noturno. Os resultados foram analisados individualmente e inter-grupos com a finalidade de se obter um panorama geral do grau de eficácia adaptativa desses alunos. Com base nos resultados obtidos, verificou-se que embora alguns alunos apresentassem dificuldades nos setores Afetivo-Relacional e Produtividade, a grande maioria foi considerada normal .(AU)

ANSIEDADE E CONSUMO DE SUBSTÂNCIAS PSICOATIVAS EM ADOLESCENTES

Os objetivos deste estudo foram: relacionar o consumo de substâncias psicoativas e ansiedade, verificar os níveis de ansiedade e as substâncias psicoativas mais consumidas, e associar consumo de substâncias psicoativas e ansiedade entre estudantes do ensino médio de escolas públicas e particulares da cidade de Maceió. Os estudantes e as instituições que participaram da pesquisa foram selecionados por meio de amostragem não-probabilística por conveniência. Tratou-se de um estudo de delineamento correlacional. A amostra foi de 407 estudantes, com idade de 14 a 18 anos. A pesquisa foi realizada em sete escolas, sendo quatro da rede pública estadual e três da rede particular. Os participantes responderam a um questionário sóciodemográfico; à Escala de Ansiedade do Adolescente (EAA); e a um questionário sobre o consumo de substâncias psicoativas. Foi feita a análise das relações entre consumo de substâncias psicoativas e ansiedade por meio do teste qui-quadrado e exato de Fisher. O álcool foi a substância lícita mais consumida pelos estudantes, enquanto o solvente, a substância ilícita mais consumida por esse grupo. Os participantes apresentaram maior percentual no nível moderado: 28%. Verificou-se diferença estatisticamente significativa entre o consumo de substâncias psicoativas e ansiedade nos adolescentes. O uso na vida de solventes (p=0,037) e energéticos (p=0,023); uso no ano de cigarro (p=0,043) e bebidas alcoólicas (p=0,007); e uso freqüente de bebidas alcoólicas (p<0,001) relacionou-se com ansiedade moderada. Houve diferença significativa entre consumo de substâncias psicoativas e ansiedade nos tipos de escola: Na escola pública, houve relação entre estudantes que disseram consumir cigarro na vida e no ano, e entre os que fizeram uso na vida de solventes e energéticos com ansiedade grave (p=0,022; p=0,003; p=0,010;p=0=0,44, respectivamente); e entre estudantes que afirmaram ter feito consumo freqüente de bebidas alcoólicas com ansiedade moderada (p=0,007). Na escola particular, houve relação entre estudantes consumiram bebidas alcoólicas no ano com ansiedade moderada (p=0,011). A pesquisa verificou a necessidade de se realizarem projetos de prevenção de drogas e promoção de saúde que visem aumentar a reflexão sobre o estilo de vida e ansiedade.

Compatibilisation of heterogeneous polymer blends by reactive processing

Functionalisation of polystyrene, PS, and ethylene-co-propylene-co-cyclopentadiene terpolymer, EPDM, with acrylic acid, AA, in a melt reactive processing procedure, in the presence of peroxide, trigonox 101, and coagents, Divinyl benzene, DVB (for PS), and trimethylolpropane triacrylate, TRIS (for EPDM), were successfully carried out. The level of grafting of the AA, as determined by infrared analysis, was significantly enhanced by the coagents. The grafting reaction of AA takes place simultaneously with homopolymerisation of the monomers, melt degradation and crosslinking reactions of the polymers. The extent of these competing reactions were inferred from measurements of melt flow index and insoluble gel content. Through a judicious use of both the peroxide and the coagent, particularly TRIS, unwanted side reactions were minimized. Five different processing methods were investigated for both functionalisation experiments; the direct addition of the pre-mixed polymer with peroxide and reactive modifiers was found to give optimum condition for grafting. The functionalised PS, F-PS, and EPDM, F-EPD, and maleinised polypropylene carrying a potential antioxidant, N-(4-anilinophenyl maleimide), F-PP were melt blended in binary mixtures of F-PS/F-EPD and F-PP/F-EPD in the presence (or absence) of organic diamines which act as an interlinking agent, e.g, Ethylene Diamine, EDA, and Hexamethylene Diamine, HEMDA. The presence of an interlinking agent, particularly HEMDA shows significant enhancement in the mechanical properties of the blend, suggesting that the copolymer formed has acted as compatibiliser to the otherwise incompatible polymer pairs. The functionalised and amidised blends, F and A-PSIEPDM (SPOI) and F and A-PPIEPDM (SPD2) were subsequently used as compatibiliser concentrates in the corresponding PSIEPDM and PPIEPDM blends containing various weight propotion of the homopolymers. The SPD1 caused general decreased in tensile strength, albeit increased in drop impact strength particularly in blend containing high PS content (80%). The SPD2 was particularly effective in enhancing impact strength in blends containing low weight ratio of PP (<70%). The SPD2 was also a good thermal antioxidant albeit less effective than commercial antioxidant. In all blends the evidence of compatibility was examined by scanning electron microscopy.

Transition metal ion coordination in hydrophilic polymer membranes

The research described within this thesis is concerned with the investigation of transition metal ion complexation within hydrophilic copolymer membranes. The membranes are copolymers of 4-methyl-4'-vinyl-2,2'-bipyridine, the 2-hydroxyethyl ester of 4,4'- dicarboxy-2,2'-bipyridine & bis-(5-vinylsalicylidene)ethylenediamine with 2-hydroxyethyl methacrylate. The effect of the polymer matrix on the formation and properties of transition metal iron complexes has been studied, specifically Cr(III) & Fe(II) salts for the bipyridyl- based copolymer membranes and Co(II), Ni(II) & Cu(II) salts for the salenH2- based copolymer membranes. The concomitant effect of complex formation on the properties of the polymer matrix have also been studied, e.g. on mechanical strength. A detailed body of work into the kinetics and thermodynamics for the formation of Cu(II) complexes in the salenH2- based copolymer membranes has been performed. The rate of complex formation is found to be very slow while the value of K for the equilibrium of complex formation is found to be unexpectedly small and shows a slight anion dependence. These phenomena are explained in terms of the effects of the heterogeneous phase provided by the polymer matrix. The transport of Cr(III) ions across uncomplexed and Cr(III)-pre-complexed bipyridyl-based membranes has been studied. In both cases, no Cr(III) coordination occurs within the time-scale of an experiment. Pre-complexation of the membrane does not lead to a change in the rate of permeation of Cr(III) ions. The transport of Co(II), Ni(II) & Cu(II) ions across salenH2- based membranes shows that there is no detectable lag-time in transport of the ions, despite independent evidence that complex formation within the membranes does occur. Finally, the synthesis of a number of functionalised ligands is described. Although they were found to be non-polymerisable by the methods employed in this research, they remain interesting ligands which provide a startmg pomt for further functionalisation.

Synthetic, crystallographic, and computational study of copper(II) complexes of ethylenediaminetetracarboxylate ligands

Copper(II) complexes of hexadentate ethylenediaminetetracarboxylic acid type ligands Heda3p and Heddadp (Heda3p = ethylenediamine-N-acetic-N,N',N'-tri-3-propionic acid; H eddadp = ethylenediamine-N,N'-diacetic-N,N'-di-3- propionic acid) have been prepared. An octahedral trans(O) geometry (two propionate ligands coordinated in axial positions) has been established crystallographically for the Ba[Cu(eda3p)]·8HO compound, while Ba[Cu(eddadp)]·8HO is proposed to adopt a trans(O ) geometry (two axial acetates) on the basis of density functional theory calculations and comparisons of IR and UV-vis spectral data. Experimental and computed structural data correlating similar copper(II) chelate complexes have been used to better understand the isomerism and departure from regular octahedral geometry within the series. The in-plane O-Cu-N chelate angles show the smallest deviation from the ideal octahedral value of 90°, and hence the lowest strain, for the eddadp complex with two equatorial ß-propionate rings. A linear dependence between tetragonality and the number of five-membered rings has been established. A natural bonding orbital analysis of the series of complexes is also presented.

Novel pH‐and temperature‐responsive methacrylamide microgels

A novel transition temperature in MeAM copolymer microgels is reported. Despite the fact that MeAM homopolymers do not show thermosensitive properties, a specific synthetic strategy leads to a thermo-responsive swelling behavior that could be potentially useful in medical and/or industrial applications. The pH and temperature-dependent swelling response of microgels of MeAM copolymerized with 2-aminomethylpyridine and ethylenediamine is reported. The changes in particle sizes, which depend on the nature of the surrounding environment, are recorded by QELS. The relation between copolymer structure and its novel behavior is analyzed by several techniques (1H NMR, TGA).

Copper(II) complexes with unsymmetrical pentadentate ed3a-type diamino-tricarboxylate ligands. Crystal structures, configurational analysis and DFT study of complexes

The O–O–N–N–O-type pentadentate ligands H3ed3a, H3pd3a and H3pd3p (H3ed3a stands ethylenediamine-N,N,N′-triacetic acid; H3pd3a stands 1,3-propanediamine-N,N,N′-triacetic acid and H3pd3p stands 1,3-propanediamine-N,N,N′-tri-3-propionic acid) and the corresponding novel octahedral or square-planar/trigonal-bipyramidal copper(II) complexes have been prepared and characterized. H3ed3a, H3pd3a and H3pd3p ligands coordinate to copper(II) ion via five donor atoms (three deprotonated carboxylate atoms and two amine nitrogens) affording octahedral in case of ed3a3− and intermediate square-pyramidal/trigonal-bipyramidal structure in case of pd3a3− and pd3p3−. A six coordinate, octahedral geometry has been established crystallographically for the [Mg(H2O)6][Cu(ed3a)(H2O)]2 · 2H2O complex and five coordinate square-pyramidal for the [Mg(H2O)5Cu(pd3a)][Cu(pd3a)] · 2H2O. Structural data correlating similar chelate Cu(II) complexes have been used for the better understanding the pathway: octahedral → square-pyramidal ↔ trigonal- bipyramid geometry. An extensive configuration analysis is discussed in relation to information obtained for similar complexes. The infra-red and electronic absorption spectra of the complexes are discussed in comparison with related complexes of known geometries. Molecular mechanics and density functional theory (DFT) programs have been used to model the most stable geometric isomer yielding, at the same time, significant structural data. The results from density functional studies have been compared with X-ray data.

Examining the influence of fame in the presence of beauty:an electrodermal 'neuromarketing' study

The use of famous and/or attractive models in brand marketing is ubiquitous yet little work, if any, has been carried out examining differences in their efficiency in driving subsequent consumer behaviour. Such brand platforms have an emotional selling proposition (ESP) that refers to the unique personality and image attributes that a particular endorsement generates. However, celebrity endorsers are also more than likely to be considered attractive and thus differences in the ESP (if any) would be very small. Such differences in an emotional response could be measured by a participant's electrodermal activity (EDA). This is a psychophysiological response, measurement of which is sensitive enough to detect differences engendered by a particular brand platform's ESP. In the present study, EDA measurements were recorded from participants who were shown advertisements containing a target product within four different types of endorsement platforms depicting models who were either famous/non-famous or attractive/average looking. The results showed that average looking celebrity endorsers produced a greater EDA response than any of the other conditions including the attractive looking celebrity endorsers. Furthermore, this effect was only revealed from recordings taken from the left hand side of the participants. Given that the right side of the brain would orchestrate any EDA responses recorded from the subjects' left side, the current results suggest a dedicated neural response for celebrity endorsed brand platforms. Future work examining the relationship between the specific EDA signature and consumer preferences is discussed.

Crystal structure of [{Cu(H2O)(en)2}{Cu(en)2}Re6Te8(CN)6]·3H2O

The reaction of Cs4[Re6Te8(CN)6]·2H2O with Cu(en)2Cl2 in water affords crystals of a cluster complex [{Cu(H2O)(en) 2}{Cu(en)2}Re6Te8(CN)6]·3H2O. The structure of the compound is determined by single crystal X-ray diffraction (a = 10.8082(4) Å, b = 16.5404(6) Å, c = 24.6480(7) Å, β = 92.696(1)°, V = 4401.5(3) Å3, Z = 4, space group P21/n, R 1 = 0.0331, wR 2 (all data) = 0.0652). In the complex, cluster [Re6Te8(CN)6]4- anions are linked by Cu2+ cations into zigzag chains through cyanide bridges. The coordination environment of the copper cations is complemented by ethylenediamine molecules. Each of the cluster anions is additionally coordinated by a terminal fragment {Cu(H2O)(en)2}. © 2014 Pleiades Publishing, Ltd.

Cardiac Neural Crest Cells Affect the Development of the Myocardium and Conduction System in the Mouse

Neural crest cells originate from the dorsal most region of the embryonic neural tube. These cells migrate into several embryonic locations and differentiate into a variety of cell types. Cardiac neural crest (CNC) cells are a set of neural crest progenitors that aid in the proper formation of the cardiac septum, which separates the pulmonary from the systemic circulation. We have used Splotch mice to investigate whether the murine CNC cells play a role during the development oft he myocardium and the conduction system. Splotch mice carry a mutation in the P AX3 transcription factor, and display a problem in CNC cell migration. A scanning-electron-microscopy analysis of Splotch mutant-embryonic-hearts reveals abnormalities in the interventricular septum. In addition, the right and left ventricular cavities appear dilated relative to a wild type heart. Hoechst nuclei staining of Splotch heart cryosections demonstrates a decreased number of cardiomyocytes and a corresponding thinner ventricular wall. The absence of Connexin 40 in the ventricles of Splotch mutants, suggests conduction system defects. These results support the evidence that CNC cell signaling plays a role in modulating the growth and development of murine cardiomyocytes and their differentiation into conductile cells.
