Snow sampling strategy can bias estimation of meltwater fractions in isotope hydrograph separation

The Isotope based Hydrograph Separation (IHS) has been instrumental in understanding the partitioning of streamflow sources and processes. However, uncertainties persist in the accuracy of IHS estimations and the appropriate definition and sampling of endmembers. To address these uncertainties, we used field data of snowpack, snowfall, and snow meltwater isotopes (δ18O) from Pallas, Northern Finland to estimate the total meltwater contribution during the snowmelt period. We investigated the biases resulting from the application of different sampling strategies for event water endmember. The total meltwater contribution to streamflow was 59.6 % (±2% uncertainty) using the time-variant rolling runoff-corrected melt flux-weighted meltwater 18O isotope value. However, replacing it with either snowfall or winter snowpack 18O isotope weighted average values underestimated the meltwater contribution by 17.8 % or 22.6 %, respectively. Conversely, using time-variant instantaneous meltwater 18O isotope values overestimated the meltwater contribution by only 1.5 %. These discrepancies highlight the importance of choosing the appropriate endmember isotopes in IHS. The large differences in meltwater contribution for a 2-week peak discharge period based on different endmembers can lead to different interpretations of hydrological, ecohydrological, and biogeochemical processes. Thus, to better understand streamflow generation processes, we suggest using rolling runoff-corrected meltwater 18O or 2H isotope values in the IHS. In the absence of meltwater samples, the 18O or 2H isotope values of snowpack samples during the peak melt season may provide reasonable estimates of the meltwater contribution, with some minor underestimations. Our study highlights the importance of appropriate event meltwater endmember selection and sampling methodology for the IHS.

How mood is affected by environment and upsetting events: The moderating role of psychological flexibility

ABSTRACT Objective: Patients suffering from psychological disorders report decreased quality of life and low mood. The relationship of these symptoms to daily upsetting events or environments, and in the context of active coping mechanisms is poorly understood. The present study thus investigates the association between mood, psychological flexibility, upsetting events, and environment in the daily life of outpatients. Method: We investigated 80 outpatients at the beginning of treatment, using event sampling methodology (ESM). Patients’ mood, occurrence of upsetting events, current environment, and psychological flexibility were sampled six times per day during a one-week intensive longitudinal examination. Data were analyzed using linear mixed models (LMMs). Results: Participants reported worse mood the more upsetting events they experienced. Further, participants reported better mood when in private environments (e.g., with friends), and worse mood when at the hospital, compared to being at home. Higher levels of psychological flexibility, however, were associated with better mood, irrespective of the occurrence of upsetting events or current environment. Conclusion: Results suggest that mood is positively associated with psychological flexibility, not despite, but especially during the dynamic and context-specific challenges of daily life. Psychological flexibility may thus potentially act as a buffer against distress-provoking situations as patients go about their daily lives.

Is helping you helping me? The assessment of helping others using event sampling methodology in a clinical and a non-clinical sample.

Individuals diagnosed with major depressive disorder (MDD) and social phobia (SP) have difficulties in social interactions. It is unknown, however, whether such difficulties prevent them from helping others, thereby depriving them of the natural benefits of helping, such as receiving gratitude. Using event sampling methodology (ESM), individuals (MDD, n= 118; SP, n= 47; and control group, n= 119) responded to questions about the frequency of helping, in total at 5333 time points, and their well-being. Contrary to our hypothesis, individuals in the MDD, SP and control group did not differ in their helping frequency. Results did show an association between helping and well-being, such that helping is related to well-being and well-being to helping. Understanding the complex relation of helping others and well-being and how this might be used during therapy and prevention programmes are discussed.

Is giving receiving? The influence of autonomy on the association between prosocial behavior and well-being

BackgroundProsocial behavior represents an evolutionary advantage for individuals. In line with this claim, several studies showed a positive relation between prosocial behavior and well-being. However, negative relations were also reported in the literature. MethodsThis study aimed to assess the relation between prosocial behavior and well-being using an event sampling methodology. Further, we were interested in two contextual factors (closeness of the receiver and autonomy) that are believed to impact this relationship. Ninety couples (180 individuals) answered questions about their helping behavior and well-being during one week. ResultsOverall, prosocial behavior was not associated with well-being and this association was also not observed when the recipient was a close rather than a distant individual. However, prosocial behavior was positively related to well-being when individuals experienced a sense of autonomy when deciding to act prosocially. ConclusionsInterventions aiming to promote prosocial behavior should ensure that behaviors are autonomously implemented.

Automated Targeted Sampling of Waterborne Pathogens and Microbial Source Tracking Markers Using Near-Real Time Monitoring of Microbiological Water Quality

Waterborne pathogens are heterogeneously distributed across various spatiotemporal scales in water resources, and representative sampling is therefore crucial for accurate risk assessment. Since regulatory monitoring of microbiological water quality is usually conducted at fixed time intervals, it can miss short-term fecal contamination episodes and underestimate underlying microbial risks. In the present paper, we developed a new automated sampling methodology based on near real-time measurement of a biochemical indicator of fecal pollution. Online monitoring of β-D-glucuronidase (GLUC) activity was used to trigger an automated sampler during fecal contamination events in a drinking water supply and at an urban beach. Significant increases in protozoan parasites, microbial source tracking markers and E. coli were measured during short-term (<24 h) fecal pollution episodes, emphasizing the intermittent nature of their occurrence in water. Synchronous triggering of the automated sampler with online GLUC activity measurements further revealed a tight association between the biochemical indicator and culturable E. coli. The proposed event sampling methodology is versatile and in addition to the two triggering modes validated here, others can be designed based on specific needs and local settings. In support to regulatory monitoring schemes, it should ultimately help gathering crucial data on waterborne pathogens more efficiently during episodic fecal pollution events.

Having versus not having social interactions in patients diagnosed with depression or social phobia and controls

Humans need meaningful social interactions, but little is known about the consequences of not having them. We examined meaningful social interactions and the lack thereof in patients diagnosed with major depressive disorder (MDD) or social phobia (SP) and compared them to a control group (CG). Using event-sampling methodology, we sampled participants’ everyday social behavior 6 times per day for 1 week in participants’ natural environment. We investigated the quality and the proportion of meaningful social interactions (when they had meaningful social interactions) and degree of wishing for and avoidance of meaningful social interactions (when they did not have meaningful social interactions). Groups differed on the quality and avoidance of meaningful social interactions: Participants with MDD and SP reported perceiving their meaningful social interactions as lower quality (in terms of subjective meaningfulness) than the CG, with SP patients reporting even lower quality than the MDD patients. Further, both MDD and SP patients reported avoiding meaningful social interactions significantly more often than the CG. Although the proportion of meaningful social interactions was similar in all groups, the subjective quality of meaningful social interactions was perceived to be lower in MDD and SP patients. Future research might further identify what variables influenced the reinforcement of the MDD and SP patients so that they engaged in the same number of meaningful social interactions even though the quality of their meaningful social interactions was lower. Increasing awareness of what happens when patients do or do not have meaningful social interactions will help elucidate a potentially exacerbating or maintaining factor of the disorders.

How Response Styles Moderate the Relationship between Daily Stress and Social Interactions in Depression, Social Phobia, and Controls

Introduction: Stress and social isolation are potent predictors of negative health outcomes and are impacted in mood and anxiety disorders. Difficulties in social interactions have been particularly noted in people diagnosed with major depression disorder (MDD) and social phobia (SP). It remains poorly understood, however, how these variables interact on a moment-to-moment basis and which variables moderate this relationship. Psychological flexibility, or the ability to be open to experiences while maintaining engagement in valued activities, may help moderate the relationship between stress and social interaction. Objective: This study examined these variables in participants diagnosed with MDD and SP and compared them to a control group. Methods: Participants were diagnosed with a mental disorder (n = 118 MDD; n = 47 SP) or were in the control group consisting of participants without MDD or SP (n = 119). Using the event sampling methodology (ESM), participants were queried six times per day for 7 days about stress, social interactions, and emotional response (rigid vs. flexible). Results: Higher current stress levels were related to more social interactions. This relationship was even stronger in situations when response flexibility was increased, especially in the clinical groups. Conclusions: Data suggest that a healthy psychological process (flexible emotional responding) buffers the relationship between stress and social interactions. We discuss how these variables interact and whether these patterns may paradoxically contribute to the maintenance of psychopathology.

Increasing prosocial behavior and decreasing selfishness in the lab and everyday life

The tension between selfishness and prosocial behavior is crucial to understanding many social interactions and conflicts. Currently little is known how to promote prosocial behaviors, especially in naturally occurring relationships outside the laboratory. We examined whether a psychological micro-intervention would promote prosocial behaviors in couples. Across two studies, we randomized dyads of couples to a micro-intervention (15 min), which increased prosocial behaviors by 28% and decreased selfish behaviors by 35% a week later in behavioral games in a dose–response manner. Using event sampling methodology, we further observed an increase in prosocial behaviors across one week that was most pronounced in participants who received the intervention. These results from the laboratory and everyday life are important for researchers interested in prosocial behavior and selfishness and have practical relevance for group interactions.

Using Event Diaries and In-Depth Interviews for Understanding Shared Understanding in Headquarters-Subsidiary Cooperation

The paper describes the application of a qualitative diary method combined with in-depth interviews in the context of headquarters-subsidiary cooperation. We examine the distinct requirements of studying shared understanding in the case of distributed teams and argue that further research is necessary in order to explain inter-team conflicts arising from incongruent understandings and divergent expectations. Building on this research gap, we perform a case study in the headquarters of a multinational technology company and one of its subsidiaries. With the help of Event Sampling Methodology (ESM) and in-depth interviews, we were able to identify, analyze and comprehend situations characterized by lacking shared understanding. By this, our research contributes to the methodical discussion on event sampling methods and proposes new fields of application. Furthermore, it contributes to the international management literature by analyzing misunderstandings in international R&D cooperation.

The everyday lives of in- and outpatients when beginning therapy: The importance of values-consistent behavior

Background/ObjectiveThe manifestation of functional impairment in patients’ daily lives and interference with things they value is poorly understood. If values are compromised in patients, as theory suggests, social contexts (and the lack thereof) are especially important – though this is currently unexplored. We therefore examined whether daily values-consistent behavior was associated with the importance of a value and whether it involved social or non-social activity. MethodUsing Event Sampling Methodology, we examined daily values-consistent behavior in 57 transdiagnostic inpatients and 43 transdiagnostic outpatients at the beginning of treatment. Patients’ values-consistent behavior, its importance, and (social vs non-social) context was sampled six times per day during a one-week intensive longitudinal examination. ResultsAcross both groups, the probability of subsequent values-consistent behavior increased if (1) it was judged as more important by the patient or (2) if it was embedded in a social context. The probability of reporting values-consistent behavior was higher for outpatients than inpatients. ConclusionsClinicians are encouraged to examine the values of their patients more closely and to especially monitor important and/or social values. Incorporating these into clinical work might increase patients’ values-consistent behavior, which can play a role in reducing suffering.

Social Interaction in Major Depressive Disorder, Social Phobia, and Controls: the Importance of Affect

Objective: Social interactions are crucial to human beings. As technology advances, new possibilities of interaction emerge, bringing both opportunities and risks, especially when interpersonal behaviors are impaired (e.g., depression) or associated with strong fear (e.g., social phobia). The authors investigated whether technological social interactions (i.e., phone and internet/chat) are used equally as often as face-to-face social interactions in participants with mental disorders and in controls and whether differences are associated with unpleasant emotions, that is, whether the association between negative affect (NA) or positive affect (PA) differed by type of social interaction. Methods: The self-chosen social interactions of participants diagnosed with major depressive disorder (MDD) or social phobia (SP) were compared with participants without these diagnoses (control group, CG). Using event sampling methodology (ESM), participants’ everyday social behavior was sampled six times per day for one week in their natural environment. Findings/Results: The CG engaged more often in face-to-face social interactions, while participants diagnosed with MDD or SP engaged more often in phone social interactions. Across all groups, there was a positive relationship between NA and the frequency of technological social interactions, and a positive relationship between PA and the frequency of face-to-face social interactions. Conclusions: The propensity to experience higher levels of PA during face-to-face social interactions and NA during technological social interactions is important to consider when selecting and planning social interactions. Clinicians may consider exploring the social interaction patterns of their patients in the light of these findings. Likewise, developers of technological interventions and clinicians using them should consider the potential that technological social interactions may increase NA.

Measuring task conflicts as they occur: a real-time assessment of task conflicts and their immediate affective, cognitive and social consequences

When two or more individuals with different values, interests, and experiences work together, interpersonal conflicts are inevitable. Conflicts, in turn, can hinder or delay successful task completion. However, certain types of conflicts may also have beneficial effects. The literature differentiates between task conflicts (TCs) and relationship conflicts (RCs). Whether TCs are detrimental or beneficial for performance largely depends on the simultaneous occurrence of RCs. However, the reasons for the differential effects of TCs with and without RCs remain largely unknown. Therefore, we explored the underlying fine-grained mechanisms of the conflict-performance relationship in two studies. We used event-sampling methodology to track employees’ conflicts in the field (study 1) and we examined conflicts in a controlled laboratory setting (study 2). We found that RCs during TCs made participants feel disrespected and thereby increased negative affect. Further, RCs during TCs impaired knowledge gain, which decreased positive affect. In turn, low positive affect explained why TCs with RCs led to poorer performance than TCs without RCs. However, neither of the two studies supported the assumption that high negative affect from RCs during TCs—by itself—had adverse effects on performance. Our results confirm previous findings of the destructive character of RCs during TCs and additionally provide new insights into the nature and complexity of workplace conflicts by introducing positive affect as a missing piece of the puzzle.

\u201cChoose change\u201d: design and methods of an acceptance and commitment therapy effectiveness trial for transdiagnostic treatment-resistant patients

BackgroundAcceptance and Commitment Therapy (ACT) has been successfully established in hundreds of efficacy trials. It is less understood, however, how ACT works in real-world settings. Furthermore, little is known about how contextual variables such as treatment setting (inpatient vs. outpatient), social network and environment of the patient impact outcome.MethodsThis paper describes the methods of the Choose Change study that compares transdiagnostic inpatients (n = 85) and outpatients (n = 85) with varying degrees of treatment experience and treatment success (i.e., no previous treatment vs. previous remission vs. treatment-resistant). Patients received ACT during an intensive treatment phase lasting approximately twelve treatment sessions, and were accompanied up to twelve months following intensive treatment. Main outcomes include symptoms, functioning, and well-being. Multiple levels of data are investigated, including treatment context, weekly assessments, a behavioral approach test, multiple follow-up phases, and ambulatory assessment using Event Sampling Methodology, to examine patients’ daily context.DiscussionWe aim to investigate antecedents, consequences, and inherent processes that contribute to the maintenance or fluctuations of psychological disorders and the efficacy of ACT treatment. Furthermore, this study intends to increase understanding of how accurately participants can report on their own experiences, in order to expand our knowledge of how to probe for such information in the future. The results of Choose Change will provide basic clinical theory and clinical care with important and meaningful insights into the effectiveness of ACT, trans diagnostically, in in- and outpatients, and in a naturalistic setting.Trial registrationThis study was retrospectively registered in the ISRCTN Registry (registration number ISRCTN11209732) on May 20th 2016.

Confronting methodological challenges in studying school leader time use through technological advancements

Among the multitude of studies that have examined an array of variables related to school leadership, only a small percentage have rigorously examined how school leaders spend their time. The complex role of school leaders poses challenges to common methods of collecting data about school leader time use, which subsequently threaten the validity of researchers’ claims. In this study we identified three prevalent challenges to studying school leader time use, and applied technological advancements in an event sampling methodology framework to mitigate the challenges associated with studying school leader time use. We used new technology and event sampling methodology to collect data, between the hours of 8 a.m. and 8 p.m. during 28 consecutive days, on the time use of 11 school leaders. Our system of notification and response achieved an overall response rate of 85% and enabled the collection of school leaders’ perceptions of their time use as they worked in multiple locations over an extended period of time. Finally, we have proposed a research agenda to study rigorously the time use of school leaders.

A multilevel investigation of antecedents of employee positive affective displays: the roles of customer negative affective displays and employee perceived supervisory support

ABSTRACTMuch past research on employee positive affective displays have explored their antecedents using a single level of analysis. The present study extends previous research by capturing the complex phenomenon of employee affective displays from a multilevel perspective. We used an event-sampling methodology to address a gap in the literature by examining affective displays at the intra-individual level and inter-individual level. Results based on 67 postal clerks completing 420 transactions in post offices in Taiwan show that customer negative affective displays were negatively correlated with employee positive affective displays. Moreover, employee perceived instrumental supervisory support had a cross-level moderating effect on the within-individual relationship between customer-displayed negative emotions and employee-displayed positive emotions. Specifically, those with perceived higher levels of instrumental supervisory support tended to express friendlier emotions while interacting with unhappy or angry customers than those with perceived lower levels of instrumental supervisory support. At the inter-individual level, results show that employee perceived emotional supervisory support was positively related to their affective displays at the aggregated employee level.

Real-time sampling of reasons for hedonic food consumption: further validation of the Palatable Eating Motives Scale.

Highly palatable foods play a salient role in obesity and binge-eating, and if habitually eaten to deal with intrinsic and extrinsic factors unrelated to metabolic need, may compromise adaptive coping and interpersonal skills. This study used event sampling methodology (ESM) to examine whether individuals who report eating palatable foods primarily to cope, to enhance reward, to be social, or to conform, as measured by the Palatable Eating Motives Scale (PEMS), actually eat these foods primarily for the motive(s) they report on the PEMS. Secondly this study examined if the previously reported ability of the PEMS Coping motive to predict BMI would replicate if the real-time (ESM-reported) coping motive was used to predict BMI. A total of 1691 palatable eating events were collected from 169 college students over 4 days. Each event included the day, time, and types of tasty foods or drinks consumed followed by a survey that included an abbreviated version of the PEMS, hunger as an additional possible motive, and a question assessing general perceived stress during the eating event. Two-levels mixed modeling confirmed that ESM-reported motives correlated most strongly with their respective PEMS motives and that all were negatively associated with eating for hunger. While stress surrounding the eating event was strongly associated with the ESM-coping motive, its inclusion in the model as a predictor of this motive did not abolish the significant association between ESM and PEMS Coping scores. Regression models confirmed that scores on the ESM-coping motive predicted BMI. These findings provide ecological validity for the PEMS to identify true-to-life motives for consuming palatable foods. This further adds to the utility of the PEMS in individualizing, and hence improving, treatment strategies for obesity, binge-eating, dietary nutrition, coping, reward acquisition, and psychosocial skills.

Gone But Not Forgotten: Virginity Loss and Current Sexual Satisfaction

Although loss of virginity remains a salient experience throughout a person's lifetime, little is known about whether this experience has implications for later sexual functioning (e.g., sexual satisfaction). Previous research tends to ask participants about their first time and their current sexual functioning concurrently, which may lead to spillover effects. The authors investigated the relation between first-time sexual intercourse and current sexual satisfaction using an event-sampling methodology. Participants were 331 undergraduate students who answered questions about their first-time sexual encounter and their current sexual functioning (e.g., sexual satisfaction, sexual depression). Participants then described and rated each of their sexual interactions for 2 weeks. Results show that participants who had more positive first-time sexual experiences (e.g., intimacy, respect) report greater feelings of sexual satisfaction and esteem and less sexual depression. A series of multilevel random coefficient modeling analyses revealed that positive first-time experiences were predictive of physical and emotional satisfaction in their current sexual interactions, even when controlling for global sexual satisfaction. These results suggest that one's first-time sexual experience is more than just a milestone in development. Rather, it appears to have implications for their sexual well-being years later.

Joy and Challenges in Improving Chronic Illness Care: Capturing Daily Experiences of Academic Primary Care Teams

Two chronic care collaboratives (The National Collaborative and the California Collaborative) were convened to facilitate implementing the chronic care model (CCM) in academic medical centers and into post-graduate medical education. We developed and implemented an electronic team survey (ETS) to elicit, in real-time, team member's experiences in caring for people with chronic illness and the effect of the Collaborative on teams and teamwork. The ETS is a qualitative survey based on Electronic Event Sampling Methodology. It is designed to collect meaningful information about daily experience and any event that might influence team members' daily work and subsequent outcomes. Forty-one residency programs from 37 teaching hospitals participated in the collaboratives and comprised faculty and resident physicians, nurses, and administrative staff. Each team member participating in the collaboratives received an e-mail with directions to complete the ETS for four weeks during 2006 (the National Collaborative) and 2007 (the California Collaborative). At the team level, the response rate to the ETS was 87% with team members submitting 1,145 narrative entries. Six key themes emerged from the analysis, which were consistent across all sites. Among teams that achieved better clinical outcomes on Collaborative clinical indicators, an additional key theme emerged: professional work satisfaction, or "Joy in Work". In contrast, among teams that performed lower in collaborative measures, two key themes emerged that reflected the effect of providing care in difficult institutional environments-"lack of professional satisfaction" and awareness of "system failures". The ETS provided a unique perspective into team performance and the day-to-day challenges and opportunities in chronic illness care. Further research is needed to explore systematic approaches to integrating the results from this study into the design of improvement efforts for clinical teams.

Mood spillover and crossover among dual-earner couples: A cell phone event sampling study.

In this study, the authors examined affective experiences of dual-earner couples. More specifically, the authors explored how momentary moods can spill over between work and family and cross over from one spouse to another. Fifty couples used their cell phones to provide reports of their momentary moods over 8 consecutive days. Results show significant spillover and crossover effects for both positive and negative moods. Work orientation moderated negative mood spillover from work to home, and the presence of children in the family decreased negative mood crossover between spouses. Crossover was observed when spouses were physically together and when the time interval between the spouses' reports was short. With this study, the authors contribute to the work and family research by examining the nature of mood transfers among dual-earner couples, including the direction, valence, and moderators of these transfers across work and family domains. The authors also contribute to the event sampling methodology by introducing a new method of using cell phones to collect momentary data.

Social Support and Well-Being in Contemporary Greek Society: Examination of Multiple Indicators at Different Levels of Analysis

An extensive and coherent body of social and psychological research has identified social ties and supportive relationships as important predictors of well-being and quality of life. This paper examines the relationships between structural and functional indicators of supportive relations and well-being in Greece at different levels of analysis based on results from three studies: (a) the European Social Survey (Study 1); (b) a cross sectional community study in Greece (Study 2); and (c) a social interactions study in Greece and the UK using an event sampling methodology (Study 3). Structural indicators of social support and life satisfaction and happiness in the first study were moderately associated. This finding was partly supported by results from the second study which revealed connections between some structural aspects of social support and well-being (happiness, anxiety, irritability) but not others. Functional aspects of social support and psychological indicators of well-being (happiness, anxiety, mental health) at the individual (Study 2) and social interaction (Study 3) levels were not associated. Cross-cultural comparisons of structural indicators of social support in Studies 1 and 3 revealed low frequency of social interactions. Also functional aspects of social support in everyday social interactions in Greece showed significantly lower levels in comparison to the UK. These findings suggest that structural and functional aspects of social support in Greece may not have the same palliative role as usually observed in the international literature and are discussed with particular attention to the level of analysis, the method, and the aspect of well-being being assessed.
