The relationship between self-esteem and job performance

The purpose of this study was to conduct a meta-analysis of the relationship between self-esteem and job performance. Overall, 49 studies were gathered and coded by their sample size, correlation estimate, and the reliability of the two measures being correlated. The data was processed using the interactive meta-analysis program called INTNL, which takes into account interactive effects between the artifacts (i.e., unreliability in the independent and dependent measures as well as sampling error). Analyses of four potential moderators were examined--type of self-esteem, the source of job performance, the type of setting and the type of self-esteem measures. Results indicated that the relationship between self-esteem and job performance is positive. However, there was only a weak support for moderating influences. Procedures to enhance employees' self-esteem are recommended. ^

A comparison of the self -esteem of freshman community college students enrolled in remedial and regular academic programs

This study examined relationships among self-esteem, remedial academic placement, ethnicity, gender, and enrollment status, using a nonexperimental, ex post facto research design. Participants were 113 freshman community college students attending Broward Community College in South Florida. The Coopersmith Self-Esteem Inventory (Adult Form) was used to measure the self-esteem of the participants. The results of this study indicate a significant difference between the mean self-esteem levels of the students enrolled in remedial academic classes (m = 66.08) and those enrolled in regular academic classes (m = 73.97). An independent samples t-test at the.05 significance level indicated that regular students were found to have higher levels of self-esteem than remedial students (t(112) = 2.14, p =.03). Two-way analyses of variance of placement status by ethnicity, of placement status by gender, and of placement status by enrollment status on self-esteem were also conducted. Interactions between placement status and the other factors were not found to be significant (p $>$.05). However, a significant main effect for ethnicity was found (p $<$.05). The results indicated that white students had a mean self-esteem level (m = 75.30) significantly higher than non-white students (m = 62.76, p =.002).^ The results of this study suggests that many community college students have problems related to self-esteem. Further research should be conducted on remedial and minority college students using a larger sample size and additional variables, such as socio-economic status. ^

Ethnic identity, self-esteem and academic factors in second -generation post-1970 Jamaican immigrants

Immigrants from Jamaica represent the largest number of migrants to the United States from the English speaking Caribbean. Research indicates that of all Caribbean immigrants they are most likely to retain the ethnic identity of their home country for the longest period of time. This dissertation explored the nature of ethnic identity and sought to determine its impact upon the additional variables of self-esteem and academic factors. A secondary analysis was carried out using data collected in the Spring of 1992 by Portes and Rumbaut on the children of immigrants attending the eighth and ninth grades in local schools in San Diego and southern Florida. A sample of 151 second-generation Jamaican immigrants was selected from the data set. ^ Six hypotheses yielded mixed results. Both parents who have a Jamaican ethnic identity present in the household are the best predictor Jamaican youth who retain a Jamaican ethnic identity. It was expected that ethnic identity would be a predictor of positive academic factors. The study showed that ethnic identity was not associated with one of the academic factors which were examined: help given with homework. ^ Neither family economic status nor parents' level of education played a significant role in the retention of Jamaican identity. Other findings were that there was no mean difference in the self-esteem scores of respondents who had similar ethnic identities to their parents and those who did not. There was also no difference found in the academic factors of either group. The study also showed that there was a small correlation between parent-child conflict and self-esteem. Specifically, the study found that the higher the conflict between youth and their parents, the lower the self-esteem of the youth. Finally it found that time lived in the U.S. was the best predictor of a higher GPA and it was also related to lower self-esteem. ^ Surprisingly, the study found that the relationship between ethnic identity and SES was the opposite of what was expected in that it found that SES was higher when there was no Jamaican identity. ^

Empowerment, social support, and self -esteem of parents involved in an elementary school program

Parent involvement (PI) in schooling has consistently been correlated with improved academic achievement in children. However, despite the apparent benefits of parent involvement, many schools serving low-income communities report consistent difficulty in facilitating the involvement of parents in their children's schooling. ^ The purpose of this exploratory pilot study was to examine key variables associated with a PI program at a school that served a low-income community. The program was selected because it sustained the involvement of parents for a prolonged period of time. It was also selected because the program was facilitated by social workers. ^ Derived from the literature, four lines of inquiry were examined: (a) the relationship between PI and parent strengths and development; (b) the relationship between PI and children's academic achievement; (c) facilitators for PI; and (d) barriers to PI. These lines of inquiry yielded the study's four primary research questions. The study employed a cross-sectional research design to address them. ^ Thirty-three parents, representing 16 school-involved (SI) parents and 17 non-school involved (NSI) parents, served as study participants. All 33 parents resided in a high poverty community. ^ Quantitative methods were selected to examine differences between study participants and PI. Measures of parental empowerment, social support, self-esteem, and direct and indirect measures of their children's academic achievement were utilized. Qualitative methods were developed to identify and describe SI and NSI parents' perceptions of facilitators for and barriers to PI. ^ This study's findings suggest that PI may yield important benefits for SI parents. These benefits include parents' perceptions of their empowerment, social support, and self-esteem. This study's findings also suggest a relationship between PI and reduced rates of children's school suspensions. This study did not, however, support relationships between PI and children's standardized test scores. This study concludes that despite the apparent benefits of PI for SI parents, PI may nonetheless be a proxy for several unspecified interventions that effect parents, children, schools and communities alike. More precise specifications and robust measures of PI are needed. ^

Development and Evaluation of a Computer-Based, Self-Management Tool for People Recently Diagnosed with Type 2 Diabetes

Aim. The purpose of this study was to develop and evaluate a computer-based, dietary, and physical activity self-management program for people recently diagnosed with type 2 diabetes. 
Methods. The computer-based program was developed in conjunction with the target group and evaluated in a 12-week randomised controlled trial (RCT). Participants were randomised to the intervention (computer-program) or control group (usual care). Primary outcomes were diabetes knowledge and goal setting (ADKnowl questionnaire, Diabetes Obstacles Questionnaire (DOQ)) measured at baseline and week 12. User feedback on the program was obtained via a questionnaire and focus groups. Results. Seventy participants completed the 12-week RCT (32 intervention, 38 control, mean age 59 (SD) years). After completion there was a significant between-group difference in the “knowledge and beliefs scale” of the DOQ. Two-thirds of the intervention group rated the program as either good or very good, 92% would recommend the program to others, and 96% agreed that the information within the program was clear and easy to understand. 
Conclusions. The computer-program resulted in a small but statistically significant improvement in diet-related knowledge and user satisfaction was high. With some further development, this computer-based educational tool may be a useful adjunct to diabetes self-management.

Diferenças no Funcionamento Emocional, Comportamental e Social (Roberts Apperception Test for Children) e na Autoestima (Rosenberg Self Esteem Scale) entre Jovens Institucionalizados e Não Institucionalizados

Objetivos: A institucionalização é, habitualmente, um momento gerador de sentimentos negativos, tais como a perda e o abandono, fragilizando os jovens envolvidos neste processo e, eventualmente, condicionando o seu funcionamento emocional, comportamental e social. O nosso estudo tem como objetivos: 1) verificar a existência de diferenças entre uma amostra de jovens institucionalizados e uma amostra de jovens não institucionalizados nas dimensões de um instrumento que avalia o funcionamento social, comportamental e emocional (Roberts Apperception Test for Children/RATC) e na autoestima (Rosenberg Self Esteem Scale/RSES); 2) explorar se existem diferenças entre as duas amostras ao nível de diferentes variáveis sociodemográficas, familiares e clínicas (e.g. história de sintomas depressivos em toda a vida e atual). Método: A amostra é composta por 60 jovens, 30 não institucionalizados (subamostra de controlo) e 30 institucionalizados (entre os 10 e os 15 anos de idade). A amostra de controlo respondeu a um questionário sociodemográfico e à Rosenberg Self Esteem Scale (RSES). Os jovens institucionalizados responderam a esta escala e a algumas perguntas do questionário sociodemográfico, tendo outras sido completadas com base nos processos da instituição. O autor administrou, junto das duas subamostras, o Roberts Apperception Test for Children (RATC). Resultados: Não foram encontradas diferenças estatisticamente significativas entre as duas amostras, no que diz respeito à RSES. Quanto ao RATC, foram encontradas diferenças estatisticamente significativas no que diz respeito apenas a quatro dimensões: Suporte aos outros, Identificação de problemas, Resolução 2 e Problema não resolvido. Verificaram-se associações significativas entre a pertença a uma ou outra subamostra e algumas variáveis sociodemográficas e clínicas, por exemplo, a escolaridade do pai e da mãe e a vivência de sintomatologia depressiva em toda a vida. Conclusões: No geral, o funcionamento emocional, social e comportamental, assim como a autoestima de jovens institucionalizados parece não se diferenciar grandemente dos de jovens não institucionalizados. Ainda assim, os jovens institucionalizados parecem apresentar resultados menos adaptativos em algumas dimensões, por comparação com os jovens institucionalizados.

Age and gender differences in the relation between self-concept facets and self-esteem

This study tested whether the gender intensification hypothesis applies to relations between multiple domain-specific self-concept facets and self-esteem. This hypothesis predicts gender-stereotypic differences in these relations and assumes they intensify with age. Furthermore, knowledge about gender-related or age-related differences in self-concept-self-esteem relations might provide valuable knowledge for designing effective self-esteem enhancement interventions. We investigated grade and gender differences in the relations between domain-specific self-concept facets and self-esteem within a sample of 1958 German students in Grades 3 to 6. Results indicated no difference in the self-concept - self-esteem relations between the subsamples of third and fourth graders and fifth and sixth graders or between boys and girls. These relations also did not differ between boys and girls in the subsamples of third and fourth graders and fifth and sixth graders. These results suggest self-concept-self-esteem relations to be invariant across grade levels and gender and thus did not support the gender intensification hypothesis.

Assessment of student engagement among junior high school students and associations with self-esteem, burnout, and academic achievement

The aim of the study was to investigate the structure of affective and cognitive engagement using the Student Engagement Instrument (SEI; Appleton, Christenson, Kim, & Reschly, 2006) and to examine the associations to behavioral engagement, as well as student-reported self-esteem, burnout, and academic achievement among Finnish junior high school students. The analyses were carried out in the main sample of 2,485 students, as well as in an independent sample of 821 students. The results showed that the original five-factor structure of the SEI construed along three affective and two cognitive engagement factors fit the current data relatively well. Affective and cognitive student engagement correlated positively with an independent measure of behavioral engagement. Furthermore, affective and cognitive engagement were positively associated with student-reported self-esteem and academic achievement, and negatively with school burnout. The findings provided corroborating evidence for the psychometric properties and utilization of the SEI instrument for assessing the engagement of junior high school students. (DIPF/Orig.)

Intrusion Detection Systems in SDN-based Self-Healing PMU Networks

Nowadays, Power grids are critical infrastructures on which everything else relies, and their correct behavior is of the highest priority. New smart devices are being deployed to be able to manage and control power grids more efficiently and avoid instability. However, the deployment of such smart devices like Phasor Measurement Units (PMU) and Phasor Data Concentrators (PDC), open new opportunities for cyber attackers to exploit network vulnerabilities. If a PDC is compromised, all data coming from PMUs to that PDC is lost, reducing network observability. Our approach to solve this problem is to develop an Intrusion detection System (IDS) in a Software-defined network (SDN). allowing the IDS system to detect compromised devices and use that information as an input for a self-healing SDN controller, which redirects the data of the PMUs to a new, uncompromised PDC, maintaining the maximum possible network observability at every moment. During this research, we have successfully implemented Self-healing in an example network with an SDN controller based on Ryu controller. We have also assessed intrinsic vulnerabilities of Wide Area Management Systems (WAMS) and SCADA networks, and developed some rules for the Intrusion Detection system which specifically protect vulnerabilities of these networks. The integration of the IDS and the SDN controller was also successful. \\To achieve this goal, the first steps will be to implement an existing Self-healing SDN controller and assess intrinsic vulnerabilities of Wide Area Measurement Systems (WAMS) and SCADA networks. After that, we will integrate the Ryu controller with Snort, and create the Snort rules that are specific for SCADA or WAMS systems and protocols.

Psykologinen omistajuus etätyöskentelyssä

Tämän tutkimuksen tavoitteena oli kuvata ja selittää etätyöntekijöiden työhönsä kokemaa omistajuuden tunnetta sekä sen syntymismekanismeja ja seurauksia. Lisäksi tavoitteena oli selvittää kuinka etätyön eri muodot korostuvat etätyöskentelyn oletetuissa eduissa ja ongelmissa. Etätyön muotojen osalta oli tavoitteena myös selvittää niden yhteyttä itsenäisyyden tunteeseen. Tutkielman tutkimusmenetelmä on kvantitatiivinen ja määrällistä aineistoa analysoitiin SPSS-ohjelmiston avulla. Tutkielman tutkimuskontekstina on etätyö. Tutkimuksen perusteella etätyöntekijät kokevat työnsä keskimäärin melko paljon omakseen. Tutkimustulokset osoittivat, että työtä kohtaan koettu psykologinen omistajuus syntyy kolmen ”reitin” kautta, joita ovat kohteen hallinta, kohteen perusteellinen tunteminen ja voimavarojen käyttäminen kohteeseen. Näiden ”reittien” syntymiseen taas oli positiivinen yhteys seuraavilla työn ulottuvuuksilla: työn vaatimat taidot, työn hahmottaminen, työn merkitsevyys, itsenäisyys sekä palaute työstä. Tutkimustulokset todistivat, että psykologinen omistajuus oli positiivisessa yhdeydessä työperäiseen itsetuntoon, työtyytyväisyyteen, työmotivaatioon, yksilön kehittymiseen työssään, vastuuntuntoon työtään kohtaan sekä rehtiyteen. Voimakkain yhteys psykologisella omistajuudella oli työtyytyväisyyden kanssa. Tutkimuksen perusteella voidaankin sanoa, että mitä enemmän henkilö kokee työnsä omakseen, niin sitä tyytyväisempi hän on työhönsä. Tutkimustulokset osoittivat, että etätyön muodolla on merkitystä etätyöskentelyssä koettuihin etuihin ja ongelmiin. Täysipäiväisen etätyön tekijät kokivat edut kaikista positiivisimmin ja ongelmat taas kaikista negatiivisimmin. Mobiilit työntekijät kokivat työssään alhaisempaa itsenäisyyden tunnetta kuin muiden etätyön muotojen edustajat.

Severity of malocclusion in adolescents: populational-based study in the north of Minas Gerais, Brazil

ABSTRACT OBJECTIVE To identify the factors associated with severity of malocclusion in a population of adolescents. METHODS In this cross-sectional population-based study, the sample size (n = 761) was calculated considering a prevalence of malocclusion of 50.0%, with a 95% confidence level and a 5.0% precision level. The study adopted correction for the effect of delineation (deff = 2), and a 20.0% increase to offset losses and refusals. Multistage probability cluster sampling was adopted. Trained and calibrated professionals performed the intraoral examinations and interviews in households. The dependent variable (severity of malocclusion) was assessed using the Dental Aesthetic Index (DAI). The independent variables were grouped into five blocks: demographic characteristics, socioeconomic condition, use of dental services, health-related behavior and oral health subjective conditions. The ordinal logistic regression model was used to identify the factors associated with severity of malocclusion. RESULTS We interviewed and examined 736 adolescents (91.5% response rate), 69.9% of whom showed no abnormalities or slight malocclusion. Defined malocclusion was observed in 17.8% of the adolescents, being severe or very severe in 12.6%, with pressing or essential need of orthodontic treatment. The probabilities of greater severity of malocclusion were higher among adolescents who self-reported as black, indigenous, pardo or yellow, with lower per capita income, having harmful oral habits, negative perception of their appearance and perception of social relationship affected by oral health. CONCLUSIONS Severe or very severe malocclusion was more prevalent among socially disadvantaged adolescents, with reported harmful habits and perception of compromised esthetics and social relationships. Given that malocclusion can interfere with the self-esteem of adolescents, it is essential to improve public policy for the inclusion of orthodontic treatment among health care provided to this segment of the population, particularly among those of lower socioeconomic status.
