Background: Adolescents spend a large percentage of their time at school, where learning and achievement are important activities that are vital to their future educational success and subsequent career opportunities. However, studies reveal a significant drop in satisfaction and performance during the teenage years.

Aim: Based on the ecological model, this study aims to explore the relationship dynamics between contextual (school climate) and psychological (emotional intelligence and resilience) variables, life satisfaction and perceived academic performance, analysing, to this end, four theoretical models grounded in previous research.

Results: School climate and life satisfaction were found to directly influence perceived academic performance, whereas emotional intelligence and resilience did so indirectly, with the full mediation of life satisfaction.

A performance is an act or process of staging or presenting a play, concert, or other form of entertainment. It is also defined as the action or process of carrying out or accomplishing an action, task, or function. [1]

In the work place, job performance is the hypothesized conception or requirements of a role. There are two types of job performances: contextual and task. Task performance is dependent on cognitive ability, while contextual performance is dependent on personality.[2] Task performance relates to behavioral roles that are recognized in job descriptions and remuneration systems. They are directly related to organizational performance, whereas contextual performances are value-based and add additional behavioral roles that are not recognized in job descriptions and covered by compensation; these are extra roles that are indirectly related to organizational performance.[3] Citizenship performance, like contextual performance, relates to a set of individual activity/contribution (prosocial organizational behavior) that supports organizational culture.[4][5]

In performing arts, a performance generally comprises an event in which a performer, or group of performers, present one or more works of art to an audience. In instrumental music and drama, a performance is typically described as a "play".[6] Typically, the performers participate in rehearsals beforehand to practice the work.

An effective performance is determined by the achieved skills and competency of the performer, also known as the level of skill and knowledge. In 1994, Spencer and McClelland defined competency as "a combination of motives, traits, self-concepts, attitudes, cognitive behavior skills (content knowledge) that helps a performer to differentiate themselves as superior from the average performer".[7] A performance also describes the way in which an actor performs. In a solo capacity, it may also refer to a mime artist, comedian, conjurer, magician, or other entertainer.

Another aspect of performance that grew in popularity in the early 20th century is performance art. The origins of Performance art started with Dada and Russian constructivism groups, focusing on avant-garde poetry readings and live paintings meant to be viewed by an audience. It can be scripted or completely improvised and includes audience participation if desired.[8]

At the New School for Social Research in New York, John Cage and Allan Kaprow became involved in developing happening performance art. These carefully scripted one-off events incorporated the audience into acts of chaos and spontaneity. These happenings challenged traditional art conventions and encouraged artists to carefully consider the role of an audience.[11] In Japan, the 1954 Gutai group led by Yoshihara Jiro, Kanayma Akira, Murakami Saburo, Kazuo Shiraga, and Shimamoto Shozo made the materials of art-making come to life with body movement and blurring the line between art and theater. Kazuo Shiraga's Challenging Mud (1955) is a performance of the artist rolling and moving in mud, using their body as the art-making tool, and emphasizing the temporary nature of performance art.

Valie Export, an Austrian artist born Waltraud Lehner, performed "Tap and Touch Cinema" in 1968. She walked around the streets in Vienna during a film festival wearing a Styrofoam box with a curtain over her chest. Bystanders were asked to put their hands inside the box and touch her bare chest. This commentary on women sexualization in film focused on the sense of touch rather than sight.[12] Adrian Piper and her performance Catalysis III (1970) featured the artist walking down New York City streets with her outfit painted white and a sign across her chest that said "wet paint." She was interested in the invisible social and racial dynamics in America and was determined to encourage civic-mindedness and interruption of the system.[13][14] Carolee Schneemann, American artist, performed Interior Scroll in 1975, where she unrolls Super-8 film "Kitsch's Last Meal" from her genitals. This nude performance contributes to a discourse on femininity, sexualization, and film.

Theatrical performances, especially when the audience is limited to only a few observers, can lead to significant increases in the performer's heart rate. This increase takes place in several stages relative to the performance itself, including anticipatory activation (one minute before the start of subject's speaking role), confrontation activation (during the subject's speaking role, at which point their heart rate peaks) and release period (one minute after the conclusion of the subject's speech).[20] The same physiological reactions can be experienced in other mediums such as instrumental performance. When experiments were conducted to determine whether there was a correlation between audience size and heart rate (an indicator of anxiety) of instrumental performers, the researcher's findings ran contrary to previous studies, showing a positive correlation rather than a negative one.[21]

Heart rate shares a strong, positive correlation with the self reported anxiety of performers.[22] Other physiological responses to public performance include perspiration, secretion of the adrenal glands, and increased blood pressure.[23]

At the Trivadis CBO Days in June, well-known speakers (Tom Kyte, Jonathan Lewis, Christian Antognini, Mohamed Zait and Markus Winand) talked about different aspects of SQL performance tuning and the Oracle cost-based optimizer.

The performance then began nearly an hour after the scheduled start time and ended after only about an hour because of a curfew the city of Indio, California and Coachella organizer Goldenvoice agreed to.

Ocean was difficult to see throughout the performance, some fans and media outlets said: Variety reported he was at times blocked from view by onstage dancers, seated too far back on the stage and sometimes not shown on the large video screens.

Ocean seldom spoke to the crowd while performing, but at one point explained he decided to headline Coachella because he and his brother, who died in a car accident in 2020, used to attend the festival together.

Although the terms are sometimes used interchangeably, a company's Form 10-K is not the same as its annual report. Both include information about the company and its financial performance over the last year. But the annual report is more of a polished publication, lavishly illustrated and describing various projects and initiatives the company undertakes. The 10-K lacks such photos and graphics but generally goes into more financial details and calculations.

Other specialized financial performance indicators are more specific to certain industries. For example, companies whose sales of goods and services vary depending on the time of the year might use seasonality as a metric, measuring how a certain period or season affects the figures and outcomes.

Our previous research, based on a similar range of ESG funds, found that the performance of many of the funds deviated from that of the broader market and that part of the performance difference could be explained by exposures to style factors.1 What we did not explore in that study was the role of industry allocations.

The effect of industry allocations on performance varied significantly from year to year: Depending on the time period, the effect was positive or negative, accounting for the majority of return differences between the ESG market portfolio and the broader market in some periods and for the minority in others.

But we noticed variability not only for the entire industry allocation effect but also for the contribution of individual industries (see the right-hand side of the chart below). The 2008 global financial crisis and the response by policymakers produced particularly hefty gyrations. As might be expected, the overweight in financials hurt relative performance in 2008. This overweight then contributed positively in the following years as markets rebounded. The opposite was true for energy. The underweight in energy had a positive impact on relative performance in 2008 and a negative impact in the following years.

Among these, energy was one of the most persistent. The relationship between the performance of the energy sector and the performance of our ESG market portfolio was negative. Hence, when the energy sector outperformed the broader market, the ESG market portfolio underperformed, and vice versa. This makes intuitive sense, given that the energy sector was underweighted in the ESG market portfolio compared with the market.

In terms of performance, we found similarly diverse results across the various ESG funds. When some funds underweight an industry and others overweight the same industry in a given year, it is not surprising that these positions have opposing effects on performance.

So what are investors to take from our findings? Our results revealed that deviations in industry allocations between ESG funds and the broader market did have an impact on relative ESG fund performance. However, the impact is very time-dependent and less systematic than many investors may expect. be457b7860
