The role of behaviour‐change theory in sleep interventions with emerging adults (aged 18–29 years): a systematic review and meta‐analysis
CICPSI Investigation and Development Unit of Faculdade de Psicologia, Universidade de Lisboa, Grant/Award Number: FPUL/BI/2020/12Previous systematic reviews and meta-analysis of sleep interventions with young
adults have not reached consensus on what contributes to their efficacy. Behaviourchange theories may influence the efficacy of interventions; hence, the aim of this
research was to investigate the role of such theories in sleep interventions with this
population. Six electronic databases and reference lists were searched (April–May
2021) for published sleep behaviour-change interventions with emerging adults (aged
18–29 years) that used control groups. A selection of 20 studies fulfilled the inclusion
criteria, but only six were based on behaviour-change theories. Meta-analysis was
run with eight studies, as the others had a high risk of bias or did not present the necessary data to calculate Hedges’ g. The estimation of a random effects model for the
studies showed a small effect in the sleep quality of the participants in the experimental group (g = 0.26; 95% confidence interval 0.42 to 0.09), with low levels
of heterogeneity (I
2 = 21%), and a small 95% prediction interval ( 0.59 to 0.08).
Although we could not examine theory or any other moderators of the effect, a qualitative analysis of the behaviour-change techniques present in the interventions leads
us to hypothesise that there is not a direct link between behaviour-change techniques and the success of the intervention. Other characteristics of the interventions
may be linked to their variable levels of efficacy and should be investigated in the
future, as for now there are no answers as to what the key is for successful sleep

Still Striving After All These Years: Between Normality of Conduct and Normativity of Evaluation in Casual Relationships among College Students
This work was supported by the Portuguese Science Foundation (FCT), under Grant (number PTDC/PSI-GER/28530/2017). This work received national funding from FCT – Fundação para a Ciência e a Tecnologia, I.P, through the Research Center for Psychological Science of the Faculty of Psychology, University of Lisbon (UIDB/04527/2020; UIDP/04527/2020).Gender similarities have been detected in various sexual behaviors and attitudes in young adults, but persistent diferences
remain regarding casual sexual relationships (CSRs), with women feeling diferent external pressures than men. We set out
to study the spontaneous references made to gender similarities and diferences towards CSRs in eight focus group interviews (N=35 college-students, aged 18–28) about the characteristics of CSRs within a social-role framework. The thematic
analysis led us to the interpretation that there is an ongoing change in the acceptability of these relationships, leading to
the emergence of a single sexual standard – mostly liberal, but at times also conservative. However, diferent expectations
remain, derived from a deep-rooted traditional sexual double standard still perceived in society. Challenges to the unequal
standards and social constraints in CSRs is desired by many women, defended by men, and admired in those women whose
striving contributes to the normalization of this conduct and of how it is evaluated.info:eu-repo/semantics/publishedVersio

Integrated Scheduling of Vessels, Cranes and Trains to Minimize Delays in a Seaport Container Terminal
The multiple processes taking place on a daily basis at an intermodal container terminal are often considered individually, given the complexity of their joint consideration. Nevertheless, the integrated planning and scheduling of operations in an intermodal terminal, including the arrivals and departures of trains and vessels, is a very relevant topic for terminal managers, which can benefit from the application of Operations Research (OR) techniques to obtain near-optimal solutions without excessive computational cost. Applying the functional integration technique, we present here a mathematical model for this terminal planning process, and solve it using heuristic procedures, given its complexity and size. Details on the benchmark comparison of a genetic algorithm, a simulated annealing routine and a tabu search are provided for different problem instances
Gestão de bloco operatório : modelos de gestão e monitorização
RESUMO - A consciência de uma necessidade clara em rentabilizar a capacidade instalada e os meios tecnológicos e humanos disponíveis no Bloco Operatório e face ao imperativo
de um cabal desempenho e de uma adequada efectividade nestes serviços levou-nos
à realização deste estudo.
Objectivos: O trabalho de projecto centrou-se em quatro objectivos concretos:
Elaboração de uma grelha de observação de Modelos de Gestão de Bloco Operatório;
Observação de seis Modelos de Gestão de Blocos Operatórios em experiências
nacionais e in-loco, de acordo com a grelha de observação; Avaliação da qualidade
gestionária na amostra seleccionada à luz dos modelos existentes; Criação de uma
grelha de indicadores para a monitorização e avaliação do Bloco Operatório.
Metodologia: Na elaboração da grelha de observação dos Blocos Operatórios
recorremos a um grupo de peritos, à bibliografia disponível e à informação recolhida
em entrevistas. Aplicámos a grelha de observação aos seis Blocos Operatórios e
analisámos as informações referentes a cada modelo com a finalidade de encontrar os
pontos-chave que mais se destacavam em cada um deles. Para a elaboração da
grelha de indicadores de monitorização do Bloco Operatório realizámos uma reunião
recorrendo à técnica de grupo nominal para encontrar o nível de consenso entre os
peritos.
Resultados: Criámos uma grelha de observação de Modelos de Gestão de Bloco
Operatório que permite comparar as características de gestão. Esta grelha foi aplicada
a seis Blocos Operatórios o que permitiu destacar como elementos principais e de
diferenciação: o sistema de incentivos implementado; o sistema informático, de
comunicação entre os serviços e de débito directo dos gastos; a existência de uma
equipa de gestão de Bloco Operatório e de Gestão de Risco; a importância de um
planeamento cirúrgico semanal e da existência de um regulamento do Bloco
Operatório. Desenhámos um painel de indicadores para uma monitorização do Bloco
Operatório, de onde destacamos: tempo médio de paragem por razões técnicas,
tempo médio de paragem por razões operacionais, tempo médio por equipa e tempo
médio por procedimento.
Considerações finais: Os Blocos Operatórios devem ponderar a existência das
componentes mais importantes dos Modelos, bem como recolher exaustivamente
indicadores de monitorização. A investigação futura deverá debruçar-se sobre a
relação entre os indicadores de monitorização e os Modelos de Gestão, recorrendo à
técnicas de benchmarking. -------------------ABSTRACT - This study was driven by the need to optimise available capacity, technology and
human resources in the Operating Room and to address the corresponding goals
of adequate performance and effectiveness.
Objectives: This project focuses on four specific objectives: development of an
observation grid of operating room management models; in-loco observation and
documentation of six national operating room, according to the grid; assess the
quality of management in the selected sample relative to existing management
models; create a set of indicators for monitoring and evaluating operating rooms.
Methodology: The design of the observation grid was based on experts’
consultation, a literature survey and information gathered in various interviews. The
observation grid was applied to six operating rooms and the information for each
management model was analysed in order to find its key characteristics. We used
the Nominal Group Technique in order to develop a set of indicators for monitoring
and evaluating operating rooms.
Results: An observation grid was created for operating rooms management
models, which allowed comparing management characteristics. This grid was
applied to six operating rooms allowing disentangle its main features and
differentiating characteristics: implementation of incentive systems; IT systems
including information flow between services; inventory and expense management;
existence of a management team and effective risk management; importance of
weekly planning and regulations. We designed a set control indicators, whose
major characteristics are the following: the average down time due to technical
reasons, the average down time due to operational reasons, the average time per
team and the average time per procedure.
Final Conclusions: Operating rooms should consider the most relevant
characteristics of management models and collect exhaustive information on control
indicators. Future research should be devoted to assessing the operating room
performance according to management models, using control indicators and
benchmarking techniques
Multiple Casual Sex Scripts: Shared Beliefs about Behavior among Portuguese Emerging Adults
Objective: Empirical research to differentiate casual sex scripts is still limited. We aimed to
ascertain the sexual scripts for three main types of casual sexual relationships: hookup,
friends with benefits and one-night stands.
Methods: Through a mixed-method approach, we performed a study consisting in two
sequential tasks to (1) complete three lists of script actions, and (2) identify the most
agreed-upon actions for each casual sexual relationship.
Results: An important number of actions and events were identified for the three casual sexual
scripts, reflecting a high level of elaboration and structure. Following a cognitive-script
methodology, the actions retained for the content of the script for each casual sexual relationship
were those obtaining at least 60% in respect to the mean of their centrality to the
encounter. Only 16.5% of actions were shared among the three scripts, demonstrating their
distinctiveness.
Conclusion: Knowledge about the different casual sex scripts can be used to develop relational
and personal skills within CSRs and decrease unwanted experiences such as condomless

Effects of motor imagery training of Parkinson's disease: a protocol for a randomized clinical trial
Background
Gait disorders in individuals with Parkinson’s disease (PD) may be associated with alterations in the motor control system and aggravated by psychoemotional and cognitive issues. Therapeutic strategies aimed at self-perception and motor regulation seem to be promising. Motor imagery (MI) has been shown to be one of these strategies, but there is still no clear evidence of its applicability in this population. The aim of this trial is to determine the effects of motor-imagery training on the gait and electroencephalographic activity of individuals with PD.
Methods/design
The sample will consist of 40 individuals, aged between 45 and 75 years, in the mild and moderate phase of the disease, with the ability to generate voluntary mental images. They will be assessed for cognitive level, degree of physical disability, mental-image clarity, kinematic gait variables, electroencephalographic activity and mobility. Next, subjects will be randomly assigned to an experimental group (EG) and a control group (CG). The EG will perform motor imagery and gait, while the CG will only engage in gait exercises. Twelve training sessions will be conducted lasting up to 90 min each, three times a week, for 4 weeks. The subjects will be reassessed on the kinematic variables of gait, electroencephalographic activity and mobility at 1, 7 and 30 days after the final training session.
Discussion
The results may provide an important advance in neurological rehabilitation where an easy-access and low-cost intervention may help to improve gait, electroencephalographic activity and mobility in individuals with PD
