Happy, and they know it? The roles of positive affectivity, intrinsic motivation and network building on LinkedIn on employment predictions
PurposeDrawing on trait activation theory, this study examines the influence of positive affectivity on employment predictions (e.g. the probability of obtaining an interview and being hired) via intrinsic motivation and network building on LinkedIn.Design/methodology/approachMultisource field data were collected from student job seekers (n = 179) searching for an internship over two points with a six-month time separation between the first and second data collection.FindingsStructural equation modeling (SEM) analyses revealed marginal support for the mediating roles of intrinsic motivation and network building in positive affectivity’s indirect effect on employment predictions about the probability of obtaining an interview and being hired.Research limitations/implicationsThis study extends research on job search networking/selection by demonstrating the sequential process through which job seekers’ positive affectivity influences employment predictions, emphasizing the intermediary roles of intrinsic motivation and network building on LinkedIn.Practical implicationsJob seekers, recruiters and career counselors should consider network building on LinkedIn as a relevant expression of positive affectivity.Originality/valueWe apply trait activation theory as an overarching framework to examine how an affective between-person difference is expressed via intrinsic motivation and network building and is, at the same time, perceived and valued by employers on LinkedIn.

Supervisors’ self-disclosure enhances subordinates’ trust: the mediating role of subordinates’ charismatic attributions
PurposeDrawing on a cognitive attribution approach to charismatic leadership, this study identifies an overlooked influence behavior – supervisor self-disclosure of a traumatic loss as contributing to subordinate charismatic attributions (e.g. idealized influence) and trust toward their supervisor.Design/methodology/approachEmploying an experimental vignette method, participants (n = 201) were assigned to one of two conditions: (1) supervisor self-disclosure of traumatic loss or (2) control condition, and then reported on charismatic attributions about the supervisor in the scenario and trust toward the supervisor.FindingsThe results revealed that supervisors’ self-disclosure to subordinates influences subordinate attributions of charisma toward their supervisors and affective-based, cognitive-based trust.Research limitations/implicationsWhile an experimental approach supports causal inference, future research may consider the long-term effects of supervisors’ self-disclosure on subordinates’ attributions and trust.Practical implicationsSelf-disclosure may be used authentically but cautiously to build relationships with subordinates and potentially benefit management development programs.Originality/valueThis study provides the first empirical insights into how a supervisor’s disclosure of a traumatic loss – an uncharted territory – affects subordinates’ perceptions of the supervisor’s charisma and subsequent trust.

Plant uptake of nitrogen and phosphorus among grassland species affected by drought along a soil available phosphorus gradient
Aims
Here we assessed N and P uptake of four grassland species grown together in response to a short-term drought event along a soil P gradient.
Methods
We used
15
N and
32
P tracers to examine uptake of N and P by the grasses
Bothriochloa macra
,
Themeda triandra
,
Lolium perenne
and
Microlaena stipoides
grown together in pots with initial available P levels of 3, 8, 12, 20 mg P kg
−1
soil. Soil moisture in half the pots was reduced from 60 to 30% water holding capacity during a 7-day period to simulate drought.
Results
Plant P uptake was strongly reduced by drought in all species across all P levels, much more so than N uptake, indicating decoupling in N and P uptake. Soil available P (Bray method) was not affected by drought, suggesting that the reduced P uptake with drought was due to reduced soil P mobility. Plant competition for N and P changed with drought and soil P levels, where relatively more N and P was taken up with drought by
M. stipoides
at the lowest soil P level.
Conclusions
We showed that greater reductions in P than in N uptake and shifts in N and P uptake among species caused by a short-term drought have strong consequences for plant growth.

Assessment scales in stroke: clinimetric and clinical considerations
As stroke care has developed, there has been a need to robustly assess the efficacy of interventions both at the level of the individual stroke survivor and in the context of clinical trials. To describe stroke-survivor recovery meaningfully, more sophisticated measures are required than simple dichotomous end points, such as mortality or stroke recurrence. As stroke is an exemplar disabling long-term condition, measures of function are well suited as outcome assessment. In this review, we will describe functional assessment scales in stroke, concentrating on three of the more commonly used tools: the National Institutes of Health Stroke Scale, the modified Rankin Scale, and the Barthel Index. We will discuss the strengths, limitations, and application of these scales and use the scales to highlight important properties that are relevant to all assessment tools. We will frame much of this discussion in the context of \"clinimetric\" analysis. As they are increasingly used to inform stroke-survivor assessments, we will also discuss some of the commonly used quality-of-life measures. A recurring theme when considering functional assessment is that no tool suits all situations. Clinicians and researchers should chose their assessment tool based on the question of interest and the evidence base around clinimetric properties.

Bouncing back: HR professionals' experiences during times of disruption
PurposeThis study investigates human resource (HR) professionals' experiences during the COVID-19 pandemic.Design/methodology/approachThe study involves in-depth, semi-structured interviews with 37 HR professionals purposefully selected based on their prior involvement in managing pandemic-related challenges.FindingsThe findings reveal that HR professionals faced intensified organizational demands, leading to expanded job roles, increased workload, a change in pace and emotional pressures. However, participants exhibited resilience by drawing from and creating various job resources to cope with these demands. Our findings also show that despite HR professionals being central to creating workplace support and wellness initiatives, their well-being needs were often overlooked as they prioritized supporting others.Research limitations/implicationsThe study contributes to research on the experiences of HR professionals during the pandemic and to job-demands resources (JD-R) theory by incorporating context-specific demands, resources and coping strategies specific to HR professionals.Practical implicationsLessons learned for organizations and HR professionals are discussed in relation to creating conditions of organizational support and resource availability for HR professionals.Originality/valueThis study extends research on the mental health and well-being of HR professionals during the pandemic by providing a novel lens on linkages between job demands, job resources and self-regulation strategies.

Clinical impact of early diagnosis of autism on the prognosis and parent-child relationships
Autism spectrum disorder (ASD) refers to a lifelong condition that usually appears in late infancy or early childhood, and is characterized by social and communication deficits that impede optimal functioning. Despite widespread research and greater public awareness, ASD has an unclear etiology and no known cure, making it difficult to acquire accurate and timely diagnoses. In addition, once an ASD diagnosis is made, parents find it challenging to navigate the healthcare system and determine which interventions are most effective and appropriate for their child. A growing body of evidence supports the value of early diagnosis and treatment with evidence-based interventions, which can significantly improve the quality of life of individuals with ASD as well as of their carers and families. Particularly noteworthy are early interventions that occur in natural surroundings and can be modified to address age-related goals throughout the lifespan. Therefore, the purpose of this review is to: 1) provide readers with a brief background related to ASD; 2) describe commonly used screening instruments and tools for early diagnosis; 3) describe early interventions that have empirical support; and 4) discuss how the parent-child and family relationships can be affected through this process. This information can provide professionals with information they can use to assist families who make critical and potentially life-changing decisions for children with ASD.
