Características do trabalho e desempenho adaptativo: O papel da satisfação com o trabalho e do suporte organizacional percebido
O presente estudo tem o propósito de aprofundar o conhecimento científico acerca do
desempenho adaptativo e os seus preditores.
A globalização, a inovação tecnológica e a volatilidade dos mercados representam alguns
dos maiores desafios sentidos pelas organizações, tornando-se imprescindível compreender o
modo como os colaboradores evidenciam a sua capacidade para desempenhar comportamentos
adaptativos, à luz das características de trabalho (especificamente, complexidade, feedback da
chefia e dos colegas e workload) e da satisfação com o trabalho. Igualmente pertinente foi
averiguar o papel do suporte organizacional percebido na relação das características do trabalho
com o desempenho adaptativo.
Os dados foram recolhidos através de um inquérito online, no qual participaram 125
indivíduos.
Os resultados revelaram-se coerentes com as hipóteses formuladas, constatando-se que o
desempenho adaptativo é influenciado positivamente pelas características do trabalho
averiguadas. Verificou-se ainda que a satisfação com o trabalho medeia a relação entre o
feedback da chefia e colegas e o desempenho adaptativo. Finalmente, confirmou-se que o
suporte organizacional percebido modera a relação entre o workload e o desempenho adaptativo
no sentido em que quando a perceção de suporte organizacional é elevada, o workload elevado
está associado uma menor frequência de desempenho adaptativo dos colaboradores. Já em
níveis de suporte organizacional inferiores, o efeito do workload sobre o desempenho
adaptativo aumenta.
Em termos teóricos e práticos esta investigação pode contribuir para que instituições de
ensino e organizações criem estratégias que lhes permitam melhorar o desenvolvimento da
satisfação com o trabalho e das características do trabalho essenciais para o desempenho
adaptativo.This study aims to deepen scientific knowledge about adaptive performance and its predictors.
Globalization, technological innovation and market volatility represent some of the biggest
challenges faced by organizations, making it essential to understand how employees show their
ability to perform adaptive behaviors, in light of work characteristics (specifically, complexity,
feedback from management and colleagues and workload) and job satisfaction. Equally
important was to investigate the role of perceived organizational support in the relationship
between work characteristics and adaptive performance.
The data were collected through an online survey, in which 125 individuals participated.
The results proved to be consistent with the hypotheses formulated, showing that the
adaptive performance is positively influenced by the work characteristics investigated. It was
also found that job satisfaction mediates the relationship between feedback from management
and colleagues and adaptive performance. Finally, it was confirmed that the perceived
organizational support moderates the relationship between the workload and adaptive
performance in the sense that when the perception of organizational support is high, the high
workload is associated with a lower frequency of adaptive performance of employees; At lower
organizational support levels, the effect of workload on adaptive performance increases.
In theoretical and practical terms, this research can contribute for educational institutions
and organizations to create strategies that allow them to improve the development of job
satisfaction and work characteristics essential for adaptive performance
Selecting Shots for Demographic Fairness in Few-Shot Learning with Large Language Models
Recently, work in NLP has shifted to few-shot (in-context) learning, with
large language models (LLMs) performing well across a range of tasks. However,
while fairness evaluations have become a standard for supervised methods,
little is known about the fairness of LLMs as prediction systems. Further,
common standard methods for fairness involve access to models weights or are
applied during finetuning, which are not applicable in few-shot learning. Do
LLMs exhibit prediction biases when used for standard NLP tasks? In this work,
we explore the effect of shots, which directly affect the performance of
models, on the fairness of LLMs as NLP classification systems. We consider how
different shot selection strategies, both existing and new demographically
sensitive methods, affect model fairness across three standard fairness
datasets. We discuss how future work can include LLM fairness evaluations
The Semantic Reader Project: Augmenting Scholarly Documents through AI-Powered Interactive Reading Interfaces
Scholarly publications are key to the transfer of knowledge from scholars to
others. However, research papers are information-dense, and as the volume of
the scientific literature grows, the need for new technology to support the
reading process grows. In contrast to the process of finding papers, which has
been transformed by Internet technology, the experience of reading research
papers has changed little in decades. The PDF format for sharing research
papers is widely used due to its portability, but it has significant downsides
including: static content, poor accessibility for low-vision readers, and
difficulty reading on mobile devices. This paper explores the question "Can
recent advances in AI and HCI power intelligent, interactive, and accessible
reading interfaces -- even for legacy PDFs?" We describe the Semantic Reader
Project, a collaborative effort across multiple institutions to explore
automatic creation of dynamic reading interfaces for research papers. Through
this project, we've developed ten research prototype interfaces and conducted
usability studies with more than 300 participants and real-world users showing
improved reading experiences for scholars. We've also released a production
reading interface for research papers that will incorporate the best features
as they mature. We structure this paper around challenges scholars and the
public face when reading research papers -- Discovery, Efficiency,
Comprehension, Synthesis, and Accessibility -- and present an overview of our
progress and remaining open challenges
