Réactions du chef de PME après utilisation d'un système d'évaluation multi-source

Résumé : Dans une ère de concurrence économique accrue, les organisations éprouvent de plus en plus le besoin de mesurer le rendement de leurs employés, y compris celui de leurs dirigeants. À cette fin, l'évaluation demeure un outil de gestion privilégié. Au nombre des systèmes d'évaluation existants, le feed-back multi-source (FMS) — ou feed-back 360°— est en progression. Malheureusement, on ne connaît pas encore très bien l'incidence de ce type de système, la littérature étant plutôt muette sur ce qu'il donne concrètement et, particulièrement, sur la réaction des évalués subséquemment à l'obtention de leur rapport d'évaluation. Il ressort néanmoins de certaines études que les dirigeants, et surtout, les chefs se sentent laissés à eux-mêmes quant à l'évaluation de leurs compétences. Il y a quelques années, à la demande du Groupement des chefs d'entreprise du Québec (GCEQ), un instrument de type multi-source a été conçu par le Laboratoire de recherche sur la performance des entreprises (LaRePe), afin de mesurer spécifiquement la performance des chefs d'entreprise comme leader. À ce stade-ci, les promoteurs désirent mieux comprendre l'incidence de l'utilisation de leur outil : le PDG-Leadership. Pour combler les lacunes de la littérature, et aussi pour répondre au besoin du GCEQ, la présente thèse porte sur la réaction des chefs à la suite de la réception de leur rapport d'évaluation. L'objet de la recherche est double : il s'agit d'examiner les variables qui influencent le fait que les évalués entreprennent des actions à la suite de leur feed-back (considération théorique) et, d'autre part, de connaître davantage ces actions entreprises bref, ce que le système de feed-back multi-source XFMS) donne vraiment (considération pratique). Afin de mener à bien la recherche, une résidence a été réalisée. Elle a fourni le contexte pour élaborer un questionnaire d'enquête s'appliquant particulièrement aux chefs d'entreprise. L'enquête a permis de rejoindre 351 dirigeants ayant été évalués au moins une fois par l'entremise du PDG-Leadership. De ce nombre, 87 répondants, membres du Groupement se sont manifestés. Le cadre conceptuel utilisé consiste en une adaptation du modèle proposé par Smither, London et Reilly (2005a). comporte sept variables, desquelles ont été tirées cinq hypothèses de recherche. Quatre hypothèses ont été rejetées alors qu'une autre ne s'est avérée supportée que pour le groupe constitué des femmes faisant partie de l'échantillon. De plus, il est intéressant de constater que ce n'est pas le feed-back (rapport) qui déclenche l'acceptation puis les actions, mais une attitude personnelle représentée par la possibilité d'un changement perçue (V4). Chez les chefs, il ne se produit donc pas de réaction en chaîne comme le suppose le modèle théorique utilisé. Il semble que ce soit plutôt la possibilité de changement perçu qui est à la base du fait d'entreprendre des actions, laquelle s'apparente au sentiment d'auto-efficacité défini par Bandura (2007). Les données recueillies auront aussi servies à générer de nouvelles connaissances et à faire ressortir une liste de 112 actions que les chefs disent avoir engagées à la suite de l'obtention de leur rapport d'évaluation. Cette liste a permis de faire une catégorisation des actions posées. Les actions qu'ils entreprennent sont toutefois davantage dirigées vers l'amélioration de l'organisation que vers leur propre amélioration. Il s'agit là, d'une des contributions de la présente thèse.||Abstract : In a context of intense economic competition, organizations are increasingly using instruments of performance evaluation. The multi-source feedback or 360 [degrees] is one of those. The literature seems still silent on what type of evaluation is really about the reaction it generates among evaluated. In response to a request from the Groupement des chefs d'entreprise du Québec (GCEQ), a System of multi-source assessment was designed by the Laboratoire de recherche sur la performance des entreprises (LaRePe). The PDG-Leadership, specifically used to measure the skills of managers of SMLs as a leader. After some years of use, developers want to better understand its impact in order to improve it and make it even better. To address these theoretical and practical considérations, a survey was conducted among 87 business leaders from Quebec who had already been assessed using this tool. This research bas the purpose, the validation of a preliminary model proposed by Smither, London, and Reilly, 2005a, to examine the variables that influence that evaluated undertake actions as a result of their feedback and the other, to know these actions, in short, that the System of feed-back multi-source (FMS) really. From the analysis of data collected, a list of 112 shares was established. In turn, this led to a categorization of actions taken. Although the FMS system is effective, it should be noted that entrepreneurs seem to react differently from other catégories assessed.

O Contributo dos Sistemas de Informação para a Eficácia da Liderança e para a Mudança do Comportamento Organizacional

O presente trabalho debruça-se sobre os constructos da liderança e do comportamento de auto-eficácia da liderança nas organizações. Reflecte-se sobre a importância dos sistemas de informação no clima organizacional, com efeitos sobre a eficácia na liderança. Trata-se de uma perspetiva pertinente na conjuntura organizacional atual, dado que incide sobre valores patrimoniais intangíveis que, quando dinamizados, dão suporte à performance organizacional. A nossa preocupação central é a auto-eficácia. Através dela pretende-se melhorar a eficiência organizacional, porque minimiza prejuízos e desperdícios. Também se relaciona a eficácia com o desempenho da liderança organizacional e com o capital ‘confiança’. Dessa forma, os novos caminhos passam por auscultar a percepção dos colaboradores sobre a importância da cultura organizacional face ao desempenho e à eficácia de longo prazo na organização. Com a presente reflexão, evidencia-se que a espiritualidade no local de trabalho é um factor de apoio ao desenvolvimento holístico dos colaboradores. Fica sublinhado que é fundamental que os líderes tenham noção e consciência de “si” e dos seus papéis, e como estes se reflectem no seu comportamento quotidiano na organização. O estudo assenta num trabalho de campo, elaborado numa organização intensiva em informação e que presta serviços de consultoria e informática. Os resultados apurados tentam dizer que, globalmente, no estudo longitudinal das hetero-percepções dos gestores directos e indirectos, o gap cultural diminuiu em todas as dimensões relativas às competências dos papéis, sendo vital destacar o quadrante designado por Apoio. As hetero-percepções dos gestores directos demonstram que o menor gap cultural mantem-se no quadrante de Objectivos Racionais e Competir no modelo de CVF, caracterizado por uma cultura de mercado, e relacionado com a fase da Combinação no modelo de SECI (processos que fomentam os relacionamentos e intercâmbios informais – conversão do conhecimento explícito para o explícito). Enquanto que o maior gap cultural reside no quadrante Apoio e Colaborar no modelo CVF, relacionado com a fase da Socialização no modelo de SECI (processos que fomentam os relacionamentos e intercâmbios informais – conhecimento tácito para tácito). Como o gap cultural diminuiu em todas as dimensões, pode realçar uma melhoria das percepções do desempenho organizacional. Contudo, um resultado inesperado está associado ao quadrante Apoio com a cultura de clã, uma vez que são os gestores indirectos na empresa em estudo que fomentam esta cultura, e não os gestores directos, conforme seria desejável. Um resultado favorável para o estudo da auto-eficácia da liderança demonstra que as médias são mais elevadas para atributos de Gestão e Resolução de Problemas. Os resultados que não corresponderam às expectativas iniciais estão associados às médias baixas relativamente aos atributos Sociais/de Comunicação, o que pode ser uma debilidade porque seria desejável que a equipa de gestão tivesse maior sensibilidade perante os capitais sociais, emocionais e espirituais, os quais estão relacionados com estes atributos.

Intervenção Precoce com Jovens Mães

A Formação Parental poderá ser a chave para o sucesso de muitas famílias, principalmente para aquelas que se encontram menos preparadas para este novo papel, que é ser mãe ou pai, sobretudo quando ainda são jovens. Desta forma, o presente estudo tem como objetivos identificar quais as necessidades de formação de mães com filhos com idades compreendidas entre os 3 e 6 anos apoiadas pelo Centro da Mãe do Funchal; aplicar um programa de formação parental adequado às necessidades das mães; avaliar a evolução das competências e estilos parentais e comparar os resultados com outros estudos. Como já supramencionado, este estudo desenvolveu-se no Centro de Mãe do Funchal, Instituição Particular de Solidariedade Social, que tem como objetivo apoiar e/ou acolher grávidas adolescentes e jovens mães, com os seus filhos, em situação de risco. As participantes do estudo foram três assistentes sociais, uma psicóloga e seis jovens mães de crianças em idade pré-escolar, apoiadas pelo Centro de Mãe. A identificação das necessidades de formação das mães foi concretizada recorrendo a entrevistas semiestruturadas. Posteriormente, procedemos à adaptação de um programa de formação parental, baseando-o no programa “Escola de Mães” do estudo de Bernardo (2013). Após as alterações necessárias ao programa de formação parental, este foi aplicado às mães. Com o objetivo de avaliar a evolução das competências e estilos parentais, foi efetuada também uma entrevista antes e após a frequência da formação parental. De forma a consubstanciar esta avaliação foram utilizados três instrumentos validados para a população portuguesa, designadamente o Questionário de Estilos Parentais – Pais adaptado de Parental Authority Questionnaire PAQ, de Buri (1991, cit in Pires et al.,2011), a Escala de Estima de Si - S.E.R.T.H.U.A.L. adaptado de Tap et al., (2009) e a Escala de Autoeficácia Parental de Brites (2010). As alterações do estilo parental praticado antes e após a frequência do programa indicam que o Programa de formação parental teve um impacto positivo junto da maioria das participantes neste estudo. É de realçar ainda a evolução das competências parentais das mães, manifestadas na sua autoestima e na relação com os seus filhos.

Perceção da autoeficácia do terapeuta e aliança terapêutica na perspetiva do cliente

Estudos recentes apontam para a necessidade de explorar o processo psicoterapêutico, na perspetiva do cliente e do terapeuta. Apesar da importância reconhecida do estudo dos mecanismos de transformação terapêutica, existe uma lacuna na investigação no que respeita à associação entre a autoeficácia dos terapeutas e a aliança terapêutica. Com efeito, o objetivo principal do presente estudo foi analisar de que forma a perceção de autoeficácia do terapeuta se relaciona com o modo como o cliente perceciona a aliança terapêutica. Participaram neste estudo 128 participantes, distribuídos por 32 terapeutas e 96 clientes, numa proporção de três clientes para cada terapeuta. A autoeficácia dos terapeutas foi avaliada através do Counselor Activity Self-Efficacy Scales (CASES-G) e a aliança terapêutica percecionada pelos clientes através do Inventário de Aliança Terapêutica (IAT; versão C reduzida). O resultados revelaram que os terapeutas percecionaram-se como eficazes em relação ao processo psicoterapêutico e que os clientes reportaram uma forte aliança terapêutica. As análises de correlação indicaram que a subescala “gestão de sessão” do CASES-G se associou negativamente à subescala “tarefas” do IAT. Estes dados sugerem que um terapeuta mais confiante na sua capacidade para desempenhar competências técnicas específicas no que respeita à gestão da sessão, poderá ter mais dificuldade em investir no cliente e no processo psicoterapêutico, o que se poderá traduzir numa menor sincronia entre ambos e num indicador de perda da qualidade da aliança terapêutica.

Key factors affecting purchase intention in Russian online context

Russian e-commerce has drawn a lot of attention in academic publications as well as in public media lately. The market is growing with a speed of rocket offering companies enormous business opportunities. However, combination of Russian culture, consumer online purchasing and decision-making process forms a subject yet completely unknown. From international online business perspective it is vital for companies to know how a culture affects consumer’s purchase decision and what are the key elements that need to be modified in order to successfully expand online operations to Russian market. Here, the main purpose is to define the key factors affecting Russian consumer’s online purchase intention. In order to answer the main research question, firstly the role of culture in purchase intention context is researched. Secondly, focus is drawn to the factors that affect online purchase intention. Lastly, it is researched how Russian culture is affecting e-commerce attributes modification. The objective is not only to expand the theoretical understanding of the subject but also to provide companies with a clear vision on how the online operations should be conducted in Russian online market. Ranganathan’s and Jha’s conceptual framework was chosen as a ground theory in this study. Here, three main categories Computer Self-Efficacy and Past Online Experience, Website Quality and Costumer Concerns form basis for the study. Various articles and academic literature supplemented this theoretical approach. Qualitative research method was adapted and the study was conducted through five expert interviews. As a conclusion it can be stated that culture forms a ground for entire purchase decision-making process in online context. Results from the interviews were grouped according to main three theoretic categories and placed with Ranganathan’s and Jha’s original framework. This formed a new theoretical framework that defines diverse factors affecting specifically Russian consumer’s online purchase intention. This study suggests that following factors need to be taking into serious consideration in Russian online context: photography style, detailed product and company information, colors, language, product variety, reviews, recommendations, strong social media presence, fast check out and minimalistic order information, counterfeit fear, cash on delivery payment, training and guidance, extensive customer service, consumers’ insecurity, inexperience, high interest for technology and their individualistic personality.

The relationship between personal cognition, social context, and knowledge sharing in global communities of practice

The purpose of this study was to identify the structural pathways of personal cognition and social context as they influence knowledge sharing behaviors in communities of practice. Based on the existing literature, ten hypotheses and a conceptual model built on the basis of the social cognitive theory were developed regarding the interrelationships of the five constructs: self-efficacy for knowledge sharing, outcome expectations, sense of community, leadership of a community, and knowledge sharing. The data were collected through an online questionnaire from the employees who have participated in communities of practice in a Fortune 100 corporation. A total of 438 usable questionnaires were collected. Overall, three analyses were conducted in order to prove the given hypotheses: (a) hypothesized measurement model fit, (b) relational and influential associations among the constructs, and (c) structural equation model analysis (SEM). In addition, open-ended responses were analyzed. The results presented that (a) hypothesized measurement models were valid and reliable, (b) personal cognitive factors, self-efficacy and outcome expectations for knowledge sharing, were found to be significant predictors of community members’ sense of community and knowledge sharing behaviors, (c) sense of community had the most significant impact on the knowledge sharing, (d) as the perceived social context, sense of community mediated the effects of personal cognition on knowledge sharing behaviors, and (e) personal cognition and social context jointly contributed to knowledge sharing. In brief, all of the hypotheses were positively supported. A conclusive summary is provided along with contributive discussion. Implications and contributions to HRD researchers and practitioners are discussed, and recommendations are provided.

Understanding what drives informal learning at work: A resource-based view.

The resource-based view identifies a number of factors that may influence employees’ informal learning. In a cross-sectional survey of 113 German employees in the energy sector, we examined a number of potential predictors of informal learning and a more positive informal learning attitude. The results showed that proactive help-seeking and professional self-efficacy were positive predictors of informal learning. Employees who were older, who enjoyed learning, sought help and were self-efficacious learners had a more positive attitude towards formal learning. Employees who had a more positive attitude about informal learning rated organisational learning provisions as less important, potentially due to being proactive help-seekers. Managers rated organisational learning resources as less important than non-managerial employees. However, managers also reported higher professional self-efficacy. These circumstances may also influence their decision-making regarding the need to provide learning resources to others in the workplace.

Cultural and Social Cognitive Predictors of Academic Satisfaction in Southeast Asian American College Students

This study examined the predictive utility of Lent’s (2004) social cognitive model of well-being in the context of academic satisfaction with a sample of Southeast Asian American college students using a cross-sectional design. Path analysis was used to examine the role of perceived parental trauma, perceived parental acculturative stress, intergenerational family conflict, and social cognitive predictors to academic satisfaction. Participants were 111 Southeast Asian American and 111 East Asian American college students who completed online measures. Contrary to expectations, none of the contextual cultural variables were significant predictors of academic satisfaction. Also contrary to expectations, academic support and self-efficacy were not directly linked to academic satisfaction and outcome expectation was not linked to goal progress. Other social cognitive predictors were related directly and indirectly to academic satisfaction, consistent with prior research. Limitations and implications for future research and practice are addressed.

Der Zusammenhang der Theorie des geplanten Verhaltens mit der selbstberichteten Individualisierungspraxis von Lehrpersonen

Einstellungen stellen als Teil der professionellen Handlungskompetenz von Lehrpersonen eine wichtige handlungsleitende Determinante des Unterrichtsgeschehens dar. Hierzu wird auf Basis der Theorie des geplanten Verhaltens ein Erwartungs-mal-Wert-theoretisches Einstellungsinstrument faktoriell validiert und der Zusammenhang der inklusiven Einstellung, Normvorstellung und Lehrerselbstwirksamkeitsüberzeugung mit der selbstberichteten Individualisierungspraxis von Lehrpersonen betrachtet. Die Ergebnisse einer exploratorischen Faktorenanalyse zeigen in Studie I drei Einstellungsfaktoren, die in Studie II konfirmatorisch bestätigt wurden. Studie III zeigt, dass die selbstberichtete Individualisierungspraxis durch die Normvorstellung und die Intention, sich den Herausforderungen eines inklusiven Unterrichtes anzunehmen, vorhergesagt werden kann. Die Intention mediiert dabei den Zusammenhang der selbstberichteten Individualisierungspraxis mit der Einstellung vollständig und mit der Normvorstellung partiell. Die Lehrerselbstwirksamkeitsüberzeugung sagt demgegenüber die selbstberichtete Individualisierungspraxis weder direkt noch indirekt vorher. (DIPF/Orig.)

The relationship between health literacy and indicators of informed decision making for colorectal cancer screening among African Americans

African Americans are disproportionately affected by colorectal cancer (CRC) incidence and mortality. CRC early detection leads to better treatment outcomes and, depending on the screening test, can prevent the development of CRC. African Americans, however, are screened less often than Whites. Aspects of decision making (e.g., decisional conflict, decision self-efficacy) can impact decision making outcomes and may be influenced by social determinants of health, including health literacy. However the relationship between social determinants of health and indicators of decision making in this population is not fully understood. Additionally, individuals have a choice between different CRC screening tests and an individual’s desire to use a particular screening test may be associated with social determinants of health such as health literacy. This study aimed to examine the relationship between social determinants of health and indicators of decision making for CRC screening among African Americans. A total of 111 participants completed a baseline and 14-month follow-up survey assessing decisional conflict, decision self-efficacy, decisional preference (shared versus informed decision making), and CRC test preference. Health literacy was negatively associated with decisional conflict and positively associated with decision self-efficacy (ps < .05). Individuals who were unemployed or working part-time had significantly greater decisional conflict than individuals working full-time (ps < .05). Individuals with a first-degree family history of CRC had significantly lower decision self-efficacy than individuals without a family history (p < .05). Women were significantly more likely to prefer making a shared decision rather than an informed decision compared to men (p < .05). Lastly, previous CRC screening behavior was significantly associated with CRC test preference (e.g., individuals previously screened using colonoscopy were significantly more likely to prefer colonoscopy for their next screening test; ps < .05). These findings begin to identify social determinants of health (e.g., health literacy, employment) that are related to indicators of decision making for CRC among African Americans. Furthermore, these findings suggest further research is needed to better understand these relationships to help with the future development and improvement of interventions targeting decision making outcomes for CRC screening in this population.

ADVANCES AND CHALLENGES OF BREASTFEEDING IN BRAZIL: AN INTEGRATIVE REVIEW

Objective: To analyze the panorama of breastfeeding in Brazil through an integrative literature review highlighting its advances and challenges. Methods: We carried out an integrative literature review in the SciELO and PubMed databases and in booklets published on the websites of the Ministry of Health and the International Baby Food Action Network (IFBAN) using the following Portuguese and English descriptors: aleitamento materno (breastfeeding), autoeficácia (self-efficacy), promoção da saúde (health promotion) and desmame (weaning) in the period from 2002 to 2015. Results: We identified at first 43 articles, 33 booklets, 1 thesis and 3 dissertations, including in the study 17 articles, 3 dissertations and 19 booklets due to information saturation. It was verified that breastfeeding rates have reduced significantly over time with direct implications in infant mortality rates, being associated with early weaning and the lack of promotion of maternal self-efficacy in the prenatal and postpartum. To change this situation, Brazil imposed a number of public policies aimed at breastfeeding success, which advocated to raise rates. Conclusion: Despite the advances, the Brazilian panorama of breastfeeding shows that the country remains below the recommendations of international organizations, and overcoming the obstacles to successful breastfeeding constitutes a major challenge for the Brazilian public health.

Substance Use and Academic Outcomes among High School Seniors: Examining the Influence of Emotional Academic Engagement

Substance use is prevalent among adolescents, with two-thirds trying alcohol and half trying an illicit drug by twelfth grade (Miech et al., 2015). Substance use is known to affect academic performance. This study utilized nationally representative data from the 2013 Monitoring the Future twelfth grade survey to examine the relationships between substance use, skipping school, grades, and academic engagement. One-quarter of respondents (26%) had never used a substance. The majority (67%) had used at least one substance during the past year. Substance use during their lifetime but not during the past year was uncommon (7%). Lifetime non-users were less likely than past-year users to skip school during the past month and to have low grades. Lifetime non-users also had greater academic self-efficacy and emotional academic engagement relative to past-year users. These findings underscore the importance of screening and intervention for substance use to promote academic achievement and adolescent wellbeing.

Individual and group antecedents of job satisfaction: a one-lab multilevel study

This study examines the simultaneous effect of individual (selfefficacy) and group variables (cohesion and gender diversity) on satisfaction. A laboratory study was conducted involving 373 college students randomly distributed across 79 small groups, who performed a laboratory task in about five hours. Two-level Hierarchical Linear Modeling (HLM) method was used. Results show the main effect from individual selfefficacy to satisfaction (both level 1), the cross-level effect from group cohesion (level 2) to individual satisfaction (level 1), and the interaction effect between self-efficacy and gender diversity to satisfaction. These results suggest that in a work group, satisfaction has a background in individual and group variables. Group cohesion and gender diversity have important effects on satisfaction. The article concludes with practical strategies and with limitations and suggestions for future research.

Locus of Control revisited: development of a new bi-dimensional measure

Locus of control (LOC) has a long tradition in Psychology, and various instruments have been designed for its measurement. However, the dimensionality of the construct is unclear, and still gives rise to considerable controversy. The aim of the present work is to present new evidence of validity in relation to the dimensionality of LOC. To this end, we developed a new measurement instrument with 23 items. The sample was made up of 697 Spanish participants, of whom 57.5% were women (M=22.43; SD= 9.19). The results support the bi-dimensionality of LOC: internal (α=.87) and external (α=.85). Furthermore, both subscales have shown adequate validity evidence in relation to self-efficacy, achievement motivation and optimism (r xy> .21). Statistically significant differences were found by sex (p < .05): men scored higher in external LOC and women in internal LOC. The validity evidence supports a two-dimensional structure for the LOC, and the measurement instrument developed showed adequate psychometric properties.
