Abstract Although responses to stressors have both adverse and positive consequences on health, many believe that stress is entirely negative. Research revealed that negative beliefs about stress can hinder well‐being and result in the avoidance of stressors. Stress‐optimizing interventions that target various stress appraisal processes may be a useful tool to reframe how individuals understand and respond to stressors. The current study extends previous findings on stress reframing and sought to examine the extent to which the presentation of information about stress outcomes may influence the individual to respond to subsequent stressors. Seventy‐seven undergraduate students (96% female) were randomized into one of four reframing conditions (balanced stress outcomes, negative stress outcomes, positive stress outcomes, and control) and underwent a psychosocial stressor. Results highlight similarities between balanced and positive framings of stress across measures of heart rate and blood pressure, whereas subjective ratings of stress and electrodermal activity suggest balanced framing may be efficacious in attenuating stress. Findings are discussed in the context of differing stress‐optimizing interventions and consider the complexities of the individual stress response.

Combat stress is an occupational hazard of the military. Soldiers who become job-ineffective due to combat stress are termed ``battle-fatigued.'' Occupational therapy, in the form of work hardening, is an important part of the management of these soldiers. Occupational therapists possess specialized knowledge and skills which make them uniquely qualified for this role. These assets include knowledge of neuromuscular and psychosocial aspects of occupational performance; the ability to do task analyses; the ability to assess occupational performance deficits; the ability to synthesize appropriate therapeutic occupations to rehabilitate functional deficits and match these to the needs of dysfunctional soldiers. These same resources serve occupational therapists equally well in civilian work hardening settings. This paper reviews the management of combat stress casualties, describes the Army units which minimize the impact of combat stress reactions, and delineates the Army occupational therapists' roles of soldier, mental health practitioner, and work hardening coordinator.

Organizations have increasingly sought to adopt innovative interventions to prevent stress-related issues. In the field of manufacturing, however, the effectiveness of these interventions remains unclear because a systematic and specific review of existing primary evidence has not been undertaken. The present systematic literature review sought to address the foregoing limitation in the literature by summarizing the main source of stress and effectiveness of stress management interventions as grounded in the context of manufacturing. Our review was limited to only randomized clinical trials (RCTs) and quasi-experimental studies and concerned employees from the manufacturing sector. Twenty-two studies on primary, secondary and tertiary interventions across four continents (Asia, Europe, USA and South America) were selected and analyzed in terms of stress factors, methodological properties and outcomes. Most of these were RCT studies (68% Vs 32%) with a majority of secondary interventions ( N ?=?11, 50%), followed by primary ( N ?=?5, 22%), tertiary ( N ?=?3, 13%), and two (9%) mixed interventions. The main outcomes included an improvement of psychological wellbeing, decreased stress reactivity and an increment of general health. There was a predominance of interventions utilizing skills programs and/or cognitive-behavioral techniques. The main source of stress reported related to professional identity, organizational deficiencies, interpersonal conflicts, physical complaints and poor work environment. Taken together, the findings provide important theoretical and practical implications for advancing the study of stress factors and the use of stress management interventions in the workplace. The prerequisite for a successful intervention is to address the real problems experienced by professionals and help them to cope with their difficult situations. The strategy of “bottom-up” offers a potential means of enhancing employees’ health and well-being; however, the most effective means of implementing these interventions needs to be understood better.

Traditionally, the components of the stress with respect to a relevant coordinate system are used for the purpose of stress visualisation and interpretation. A case for using a flow dependent measure to interpret and visualise stress is made for two dimensional flow, together with a suggestion for extending the idea to three dimensions. The method is illustrated for Newtonian and Oldroyd B fluids in both the eccentrically rotating cylinder and flow past a cylinder benchmark problems. In the context of a generalised Newtonian fluid, the relation between the flow-dependent stress measure to other field variables under certain flow conditions, is examined and is indicative of its importance in complex flow.

Abstract Under natural conditions plants are generally subjected to complex scenarios of combined or sequential environmental stresses. Among the various components of plant biochemistry modulated by abiotic variables, a pivotal role is played by antioxidant systems, including specialized metabolites and their interaction with central pathways. To help address this knowledge gap, a comparative analysis of metabolic changes in leaf tissues of the alkaloid accumulating plant Psychotria brachyceras Müll Arg. under individual, sequential, and combined stress conditions was carried out. Osmotic and heat stresses were evaluated. Protective systems (accumulation of the major antioxidant alkaloid brachycerine, proline, carotenoids, total soluble protein, and activity of the enzymes ascorbate peroxidase and superoxide dismutase) were measured in conjunction with stress indicators (total chlorophyll, ChA/ChB ratio, lipid peroxidation, H2O2 content and electrolyte leakage). Metabolic responses had a complex profile in sequential and combined stresses compared to single ones, being also modified over time. Different stress application schemes affected alkaloid accumulation in distinct ways, exhibiting similar profile to proline and carotenoids, constituting a complementary triad of antioxidants. These complementary non-enzymatic antioxidant systems appeared to be essential for mitigating stress damage and re-establishing cellular homeostasis. The data herein provides clues that may aid the development of a key component framework of stress responses and their appropriate balance to modulate tolerance and yield of target specialized metabolites.

Transcript expression profiles of rice seedlings were analyzed in response to (a) prior exposure with oxidative stress followed by heat or cold stress and (b) simultaneous exposure to oxidative stress along with heat stress or cold stress. The numbers of genes differentially regulated during stress combination of cold and oxidative stress as well as heat and oxidative stress treatments were higher when compared with the number of genes differentially regulated in response to individual stress conditions. A large number of transcript changes were noted unique to the stress combination mode as compared with when individual stresses were applied. Specific differences in the transcript expression profiles of OsHsf and OsClp gene family members were noted during combination of stresses as against individual stresses. For instance, OsHsf26 induction was specific to stress combinations, while OsHsfA2a, OsHsfA2f, and OsHsfA3 transcript levels were additively affected during combination of stresses. Unique promoter models and transcription factor binding sites (i.e. P$KNOX3_01, P$OSBZ8_Q6) were noted in the promoters of differentially regulated genes during combination of stresses. It is proposed that stress combinations represent a novel state of abiotic stresses for rice seedlings that might involve a different type of molecular response.

Brassinosteroids are found in a wide range of organisms from lower to higher plants. They are steroidal plant hormones implicated in the promotion of plant growth and development. Brassinosteroid metabolism has long been known to be altered in plants responding to abiotic stresses and to undergo profound changes in plants interacting with bacterial, fungal and viral pathogens. This review describes the role of brassinosteroids in response to various kinds of stresses via activation of different mechanisms.

Mediterranean plants are usually exposed to a combination of stresses, which may occur simultaneously or at different times throughout their life. Here, the hormonal response to high temperatures was compared in plants of three Labiatae species, including rosemary {Rosmarinus officinalis L), sage [Salvia officinalis L) and lemon balm {Melissa officinalis L). Plants exposed to increasing temperatures for 5 days were subsequently exposed to heat stress and compared to plants experiencing heat stress for the first time (controls). Despite the three species showing a similar tolerance to a single heat stress event, stress recurrence had a different impact on each species. Lemon balm was the most sensitive species to stress reiteration, showing decreasedrelative water content upon heat stress repetition, together with enhanced levels of a-tocopherol and salicylic acid (SA). Some acclimation responses were observed in rosemary and sage, including improved water contents and reduced jasmonic acid levelsin rosemary, and reduced abscisic acid (ABA) and malondialdehyde (MDA) levels in sage plants previously exposed to high temperatures. Furthermore, the response of plants to a combination of heat stress and water deficit was evaluated in plants previouslyexposed to heat stress and compared to controls. Rosemary and sage were much more resistant than lemon balm, which died when stresses were combined. Despite stress pre-exposure not having any effect on plant performance in terms of F_v/F_m, MDA and relative water content in rosemary and sage, it resulted in higher a-tocopherol levels in both species. The hormonal response differed between species: while the hormonal content did not change in sage, rosemary showed increased ABA and decreased SA levels as a result of repeated stress exposure. Overall, different stress imprints particular to each species and stress scenario were found in a-tocopherol and hormone levels, which led to similar protective effects in rosemary and sage.
