Abstract WP166: Bleeding Risks Among Hemorrhagic Stroke Patients Started on Serotonergic Antidepressants During Subacute Recovery

Background: Early initiation of antidepressants (ADs) are associated with improved functional recovery, but are associated with an increased risk of major bleeds among hemorrhagic stroke (HS) patients. Our objectives were to determine if increased bleeding risk remained if ADs were initiated during subacute recovery and if bleed risks were comparable between AD classes. Methods: A cohort of AD naive first time HS patients (ICD-10 codes 160-162) were identified from Electronic Medical Records of 70 large healthcare organizations (2003-2023). Patients without AD use were considered “No AD” whereas patients started on ADs during subacute recovery (i.e., at least 3 months after the indexed HS) were grouped as Selective Serotonin/Serotonin & Norepinephrine Reuptake Inhibitors (SSRI/SNRI) or “Other AD” (i.e., Mirtazapine, bupropion, trazodone, or tricyclic ADs). Baseline differences were adjusted for using 1:1 matched propensity score (PS). Outcomes included the 1-year risk of a major bleeding event (e.g., gastrointestinal/intracranial bleed or shock), recurrent HS, fall, ischemic stroke (IS) and death Results: The cohort consisted of n=257,595 patients split into 3 groups: No AD (n=250,103), SSRI/SNRI (n=4,180) or Other AD (n=3,312). Matching resulted in good covariate balance for both the SSRI/SNRI vs. No AD (n=8,250 patients) and Other AD vs. SSRI/SNRI (n=6,380 patients) comparisons. SSRI/SNRIs (vs. No AD) were associated with a 33% increase in the risk of a major bleed (RR: 1.33, 95%CI: 1.22-1.45) and significantly higher risks of recurrent HS, fall, IS and death. There were no significant differences in adverse outcomes between AD classes. Discussion: Increased risk of major bleeds and recurrent HS remains if ADs are started during subacute recovery, a time period which aligns with community-based recovery. Our findings may inform care practices of primary care providers and rehabilitation professionals to decrease preventable adverse outcomes.

A method for optimizing text preprocessing and text classification using multiple cycles of learning with an application on shipbrokers emails

Optimizing text preprocessing and text classification algorithms is an important, everyday task in large organizations and companies and it usually involves a labor-intensive and time-consuming effort. For example, the filtering and sorting of a large number of electronic mails (emails) are crucial to keeping track of the received information and converting it automatically into useful and profitable knowledge. Business emails are often unstructured, noisy, and with many abbreviations and acronyms, which makes their handling a challenging procedure. To overcome those challenges, a two-step classification approach is proposed, along with a two-cycle labeling procedure in order to speed up the labeling process. Every step incorporates a heuristic classification approach to assign emails to predefined classes by comparing several classification and text vectorization algorithms. These algorithms are compared and evaluated using the F1 score and balanced accuracy. The implementation of the proposed algorithm is demonstrated in a shipbroker agent operating in Greece with excellent performance, improving organization and administration while reducing expenses.

An ethical norm of long-term human survival with universal dignity

PurposeThe purpose of this study is to create an ethical norm that will help guide the human race toward long-term survival.Design/methodology/approachThe project posits a new societal ethical norm designed around a fundamental principle: the long-term survival of the human race with individual dignity. This study examines the requirements of the new norm and what is needed to achieve that goal.FindingsThere are three types of organizations that have the organizational and economic capacity to be responsible for future outcomes: governments, religions and corporations. These three types of organizations must act as if they have a moral compass that will compel them to develop and uphold the requirements for the survival of humanity with individual dignity.Research limitations/implicationsThe analysis shows that a new, broader ethical norm must be established, and this norm implies that large organizations must act with a future embracing ethical behavior.Practical implicationsThis study generates specific pathways for example: governments should adopt the just war principles and prohibitions on governments or other institutions from teaching any form of class superiority. These and other pathways are designed to diffuse threats to the fundamental principle.Social implicationsThe fundamental principle includes universal human dignity. This means that the notion of individual dignity must be defined or understood, and the requirements to attain this goal must be identified.Originality/valueThis project takes concepts from long-termism, forward-looking collective responsibility, corporate social responsibility and the global catastrophic risk institute to advocate for a new ethical norm.

Evaluation of the cyber security models implemented across common attack vectors: A review of literature

Cybersecurity is an organizational issue that should be looked at through the lens of various stakeholders. However, it is often treated as a siloed issue in which more is always seen as better. The CISOs, CIOs, and the key decision-makers struggle to understand how much security is enough. Cybersecurity solutions, referred to as controls, more often than not result in a residual risk. To assess this risk better, the security controls should be studied in further detail. The objective of this paper is to educate the audience with the various cyber security controls being used in the academia and in the industry. In order to circumvent the security issues faced by large organization, the tradeoffs of each controls should be studied further. The paper is meant to provide a balanced view providing the positive and the critical aspect of implementing some of the known security solutions. There is no one perfect formula when it comes to selecting security controls. However, picking a security control that are in line with the users’ needs will help reduce some of the risks associated with implementing the controls. An optimal solution requires a balanced approach towards the risk, cost, and benefit of the solution. The aim of the paper is to help the reader assess some of risks and the tradeoff associated with the security controls being practiced in the industry today.

Understanding the potential of market and brand orientations: An empirical investigation of the mediating role of brand equity on business performance

Brand Orientation and Market Orientation have been demonstrated to exert a significant impact on brand equity. Moreover, brand equity serves as a crucial link connecting these orientations to company performance. However, the existing literature presents a substantial gap in understanding this relationship, particularly within the context of India. To address this gap, this study proposes an innovative framework for examining the interplay between brand orientation, market orientation, business performance, and brand equity. A survey was done in northern India using a causal study design to determine cause-and-effect correlations among the components. The participants were asked to respond to an English-language questionnaire. The outcomes of the structural equation modeling (SEM) analysis support all of the proposed hypotheses. The findings of this study carry significant implications for businesses aiming to optimize their brand and market orientations while capitalizing on their brand equity to enhance their overall performance. This research offers fresh insights for businesses operating in diverse cultural and economic contexts through its innovative methodology and empirical evidence. Businesses can enhance their brand and reputation, launch tailored offerings, and gain a competitive advantage through market and brand orientation. The framework developed in this study can be adapted to other emerging economies or even larger organizations. For both businesses and academics, this research serves as a valuable resource, providing a deeper comprehension of the intricate relationship between brand orientation, market orientation, company performance, and brand equity in India and beyond.

Mitigating the adverse impact of coworker incivility on organizational deviance: The self‐regulatory roles of trait conscientiousness and gender

AbstractDespite the current knowledge about the influence of peers in the workplace, we still know relatively little about the boundary conditions that may strengthen or weaken the adverse impact of coworker‐initiated incivility on targets' behavioral outcomes. Drawing upon self‐regulation impairment theory, this study aims to shed light on the impact of coworker incivility on targets' organizational deviance (e.g., working slower and taking longer breaks) and proposes that trait conscientiousness and gender can serve as self‐regulatory resources that jointly buffer its adverse impact. Survey data were collected from 401 employees nested in 83 teams in a large public organization in Thailand. The hypotheses were tested using multilevel structural equation modeling. Two‐way interaction analyses revealed that the effect of coworker incivility on supervisor‐rated organizational deviance was less pronounced among those with high levels of conscientiousness and among female targets. Three‐way interaction effects on both self‐rated and supervisor‐rated organizational deviance were also observed. Specifically, the results showed that targets with high levels of conscientiousness, regardless of gender, showed lower tendencies to engage in organizational deviance. Conversely, among targets with low conscientiousness levels, men were most likely to engage in organizational deviance, while women were also prone to do so, albeit to a lesser extent. The present findings emphasize the importance of considering individual differences in self‐regulation when addressing the detrimental effects of incivility.

Inclusive management in a diversified cultural environment

The aim of this article is to diagnose the level of inclusion in the management of representatives of other cultures. This article introduces the idea of inclusive management, develops a model of inclusive management of an organisation in a cultural aspect, and applies the Inclusive Management Scale – an original research tool which can be used to diagnose the level of inclusion in management in the following dimensions: cognitive, affective and behavioural, and enables precise indication of strengths and weaknesses in a given area. The results of research conducted in 452 organisations based in Poland are presented. The research shows that Polish managers, with regard to the behavioural and affective dimensions, are at the first level of ethnorelativism. It should be noted that they tend to accept representatives of other cultures and undertake cooperation in spite of differences but do not have sufficient knowledge and determination on how to manage in a fully inclusive manner. Their knowledge of how to adapt and integrate foreigners should be improved. On a cognitive level, they are in a transitional phase between ethnocentric and ethnorelativist approaches to managing culturally different people. It has also been observed that managers of large organisations are more willing and better prepared to manage inclusively than managers of smaller entities.

Multiple Objective Hub Locations Problem for Medical Supply Chain Optimization (Solving Sample Problems in Large Sizes with MOPSO and NSGA II Algorithms)

Today, the problem of facility location planning is mainly from the long-term and strategic operational level of large private organizations. Based on the hub location model for the green supply chain of medical and pharmaceutical equipment, it is possible to investigate the current condition of the facilities and significantly improve the demand coverage by spending acceptable costs. Therefore, after presenting the mathematical model, validation was performed in small dimensions and then sensitivity analysis was performed on the main parameters of the model. Next, Bender's analysis algorithm was used to analyze the NP-hardness of the model. Finally, by comparing the model solving time without implementing the Benders decomposition algorithm and by using it, it is clear that in high-dimensional example problems, the Benders decomposition algorithm reaches the solution in much less time than the normal case, and according to the answers, the performance can be acceptable. In addition, to show the efficiency of the model, two meta-heuristic algorithms NSGAII and MOPSO were developed. Then, based on the analysis, it can be seen that the computational time increases exponentially with the increase in the size of the sample problems, which is a reason for the NP-Hard of the problem. However, the MOPSO algorithm is better than the NSGA II algorithm in terms of computational time up to medium size problems.

Relationship of shift work with liver enzyme abnormalities and nonalcoholic fatty liver disease: A retrospective cohort study of Thai workers in Bangkok, Thailand

Shift work, particularly night shift work, has several detrimental health outcomes. This retrospective study investigated the associations of shift work with the incidence rates of liver enzyme abnormalities and nonalcoholic fatty liver disease (NAFLD) using the annual health check-up database between 2009 and 2016 and self-administered questionnaires from two large organizations in Thailand. Among 10,205 participants, 3620 eligible participants, classified into three subgroups by their shift work status, were followed up until abnormal liver outcomes were observed. The incidence rate of abnormal outcomes was calculated, and Cox proportional hazard models were used to assess the associations. Current shift work was not associated with abnormal liver outcomes, including elevated alanine aminotransferase and aspartate aminotransferase levels, elevated lipid accumulation product (e-LAP), and elevated hepatic steatosis index (e-HSI). However, when the frequencies and duration of shift work were investigated, the duration of shift work was associated with NAFLD outcomes. Healthcare personnel with 10–20 years of shift work experience had a higher risk of e-LAP (adjusted hazard ratio [HR] = 1.31, 95% confidence interval [CI] = 1.04–1.65), while workers with more than 20 years of shift work had a lower risk of e-LAP (adjusted HR = 0.77, 95% CI–0.62–0.97). Nonhealthcare shift workers with fewer than 10 years of work exposure had a higher risk of e-HSI (adjusted HR = 4.30, 95% CI = 1.28–14.47). In summary, the shift work status was not associated with liver abnormalities, but the duration of shift work was associated with NAFLD.

The Interplay Between Helping Behavior and Absenteeism in Teams: A Longitudinal Examination of Their Reciprocal Relationship in a Public Organization.

This study employed a longitudinal model to investigate the reciprocal relationships between interpersonal citizenship behavior (OCB-I) and absenteeism at the team level. The research utilized four waves of data from a sample comprising over 5,000 employees in 168 teams within a large Canadian public organization. Drawing upon the focus theory of normative conduct and the collective identity perspective, our findings indicated that a positive change in OCB-I, which encompasses helping behaviors, led to a subsequent decrease in team absenteeism. In addition, emphasizing the identity perspective and allocation of time perspective, our study demonstrated that increased absenteeism within a given period was associated with a subsequent reduction in team OCB-I.

Enhancing resilience, coping and self-talk of employees in large organisations; the development and mixed methods piloting of an online mental health and well-being toolkit

PurposeThe mental health and well-being of employees is negatively impacted by stress, anxiety and depression. There is a need to address these issues at an organisational level to enhance workforce welfare and to decrease the number of days lost due to mental health/well-being concerns. This study aimed to evaluate a mental health and well-being toolkit designed to enhance the resilience, coping and self-talk of employees.Design/methodology/approachThe intervention was derived from counselling psychology and composed of an 8-hour programme, which was delivered over four consecutive weeks. A mixed methods approach was adopted, with the quantitative element assessing an intervention group (n = 10) and control group (n = 14) at baseline and at the end of the programme on measures of mental health and well-being. The qualitative aspect of the study involved interviews with the intervention group, which were thematically analysed..FindingsQuantitatively, the experimental group showed statistically significant improvements in elements of resilience and well-being and a reduction in stress and anxiety. Qualitatively, participants experienced a positive effect on their well-being, benefited from the learning process, applied the taught strategies widely and found the session experience positive.Research limitations/implicationsThis was a small pilot study, nevertheless, the mixed methods nature of this investigation indicates that a counselling derived online training programme can enhance the well-being of employees within large organisations.Originality/valueA remotely delivered mental health and well-being toolkit could be a useful resource to enhance the well-being of employees in all organisations.

Employees’ experiences of a large-scale implementation in a public care setting: a novel mixed-method approach to content analysis

BackgroundResearch for evidence-based interventions and strategies for implementation continues. Yet there is a continued shortage of qualified health care staff while stress and burnout are common. Health care professionals’ individual perceptions towards change needs to be considered to succeed in organisational change. It is therefore relevant to investigate how implementation processes affect employees within the health care sector. Challenges to implementation are especially large in the field of disability care. The present study aims to investigate employees’ experiences of an ongoing large-scale implementation, and what they perceived as important to succeed in a complex clinical setting.MethodsSemi-structured focus group interviews were conducted with a self-selected sample of employees from a large and complex health care organisation responsible for public disability care in a centrally located Swedish region. A mixed-method approach adapted to content analysis was performed in a three-step process. In the first round, each unit of analysis was selected and then colour coded. In a second round, the coloured units were coded according to content analysis, and categories and concepts were compared and adjusted until the two researchers reached consensus. Finally, to further complement the content analysis, a quantitative analysis of the colour categories was made.ResultsIn general, employees experienced the implementation as being insufficient, yet opinions of the process of implementation were mixed. Most positive experiences were found in relation to the outcomes that the new method had on work effectiveness and patient care. Closely related topics like time constraints, uncertainties concerning the method and the need for supportive functions reoccurred in several concepts suggesting a relationship between differing contextual factors, implementation activities and fidelity. Also evident in the results were the strain on organisational and social work environment and the importance of managers’ active leadership.ConclusionsImplementation processes are experienced as challenging for employees. Key facilitators are available support functions, clear leadership and time that is sufficient and kept sacrosanct. Leaders need to communicate how and why employees may experience implementation processes differently. The impact that organisational change has on work environment should be considered.

IT Risk Management: Towards a System for Enhancing Objectivity in Asset Valuation That Engenders a Security Culture

In today’s technology-centric business environment, where organizations encounter numerous cyber threats, effective IT risk management is crucial. An objective risk assessment—based on information relating to business requirements, human elements, and the security culture within an organisation—can provide a sound basis for informed decision making, effective risk prioritisation, and the implementation of suitable security measures. This paper focuses on asset valuation, supply chain risk, and enhanced objectivity—via a “segregation of duties” approach—to extend and apply the capabilities of an established security culture framework. The resultant system design aims at mitigating subjectivity in IT risk assessments, thereby diminishing personal biases and presumptions to provide a more transparent and accurate understanding of the real risks involved. Survey responses from 16 practitioners working in the private and public sectors confirmed the validity of the approach but suggest it may be more workable in larger organisations where resources allow dedicated risk professionals to operate. This research contributes to the literature on IT and cyber risk management and provides new perspectives on the need to improve objectivity in asset valuation and risk assessment.

Finger Vein Authentication using Neural Network

In today's rapidly evolving world, security has become a paramount concern. Biometric-based methods have emerged as a reliable and accurate means of authentication, with hand-based biometric traits being easily accessible for data collection. In this paper, we present a novel approach for authentication utilizing finger-vein images, addressing the challenges of collecting and processing biometric trait images for large organizations. However, the collection, storage, and processing of biometric trait images for a large number of employees pose significant challenges. To overcome these challenges, our proposed approach leverages deep learning techniques to authenticate individuals based on finger-vein images. The rise in technological advancements has brought about an elevated risk to both personal data and national security. Existing methods designed to safeguard crucial information from external threats were found to be insufficient. There emerged a necessity to implement more advanced technologies that could ensure a higher level of efficiency in protecting our data from unauthorized access. In this proposed method we use Sobel filter , open cv and gaussian blur for image pre-processing, sequential model with transfer learning for feature extraction and finally, Adam optimizer for decision making. The proposed model has shown 98% accuracy in authenticating finger veins. Keywords: Sobel Filter, Open CV, Sequential Model, Transfer Learning, Adam Optimiser.

Perilaku Kelompok Dalam Organisasi

Groups are part of human life. Every day people will be involved in group activities. Likewise, groups are part of organizational life. In organizations you will find many of these groups. Almost in general, people who are members of large or small organizations have a very strong tendency to seek familiarity in certain groups. Starting from the similarity of work tasks carried out, the closeness of the place of work, the frequency of meeting each other, and perhaps the similarity of shared pleasures, then closeness to each other arises. Start them grouping in certain organizations. To continue the material, we will discuss it with the following problem formulation.

From intra-team conflict to interpersonal strain: the role of leader’s interpersonal modulation of emotional responses and sex

PurposeBy integrating the conservation of resources and the emotion-as-social-information theories, this study aims to question whether the leader’s effort to calm down when team members perceive intra-team conflict (ITC) may have a counterproductive effect on their interpersonal functioning. Specifically, the authors investigated whether team members with higher individual perceptions of ITC would be more likely to experience interpersonal strain (ISW) when their team leaders downregulate or suppress their emotional responses (i.e. high interpersonal modulation of emotional responses [MER]). A further objective of the study was to examine whether this exacerbating effect would be conditional on the leader’s sex.Design/methodology/approachData were collected from 236 white collars nested in 48 teams (Msize = 6.23; SDsize = 2.69) and their respective team leaders (56.7% men) of a large organization providing financial services.FindingsMultilevel model results showed that team members confronted with higher ITC experienced higher ISW levels, especially when the leader’s interpersonal modulation of team members’ emotional responses was high (vs low). This effect was stronger when the interpersonal modulation was enacted by women (vs men) team leaders.Originality/valueThis study moves an important step forward in the conflict and ISW literature, as it is the first to identify a leader’s MER and sex as key boundary conditions under which ITC is related to team members’ ISW. The implications of these findings for theory and practice are discussed.

Antibiotic exposure is associated with decreased risk of psychiatric disorders.

Objective: This study sought to investigate the relationship between antibiotic exposure and subsequent risk of psychiatric disorders. Methods: This retrospective cohort study used a national database of 69 million patients from 54 large healthcare organizations. We identified a cohort of 20,214 (42.5% male; 57.9 ± 15.1 years old [mean ± SD]) adults without prior neuropsychiatric diagnoses who received antibiotics during hospitalization. Matched controls included 41,555 (39.6% male; 57.3 ± 15.5 years old) hospitalized adults without antibiotic exposure. The two cohorts were balanced for potential confounders, including demographics and variables with potential to affect: the microbiome, mental health, medical comorbidity, and overall health status. Data were stratified by age and by sex, and outcome measures were assessed starting 6months after hospital discharge. Results: Antibiotic exposure was consistently associated with a significant decrease in the risk of novel mood disorders and anxiety and stressor-related disorders in: men (mood (OR 0.84, 95% CI 0.77, 0.91), anxiety (OR 0.88, 95% CI 0.82, 0.95), women (mood (OR 0.94, 95% CI 0.89,1.00), anxiety (OR 0.93, 95% CI 0.88, 0.98), those who are 26-49 years old (mood (OR 0.87, 95% CI 0.80, 0.94), anxiety (OR 0.90, 95% CI 0.84, 0.97)), and in those ≥50 years old (mood (OR 0.91, 95% CI 0.86, 0.97), anxiety (OR 0.92, 95% CI 0.87, 0.97). Risk of intentional harm and suicidality was decreased in men (OR 0.73, 95% CI 0.55, 0.98) and in those ≥50 years old (OR 0.67, 95% CI 0.49, 0.92). Risk of psychotic disorders was also decreased in subjects ≥50 years old (OR 0.83, 95 CI: 0.69, 0.99). Conclusion: Use of antibiotics in the inpatient setting is associated with protective effects against multiple psychiatric outcomes in an age- and sex-dependent manner.
