Come Together, Right Now? An Empirical Study of Collaborations in the Music Industry
Authors: Deshmane Abhishek , Martínez-de-Albéniz Victor 
Published: March 2023

Artist collaborations in music have been on the rise, and they tend to produce commercially and critically successful songs. We seek to uncover the effect of these collaborative projects on career trajectories and identify the factors that lift an artist’s profile in the short and long term. We develop a theory of collaboration based on the transfer of capital between the collaborating artists that facilitates spillovers across time. To validate the theory, we use weekly radio plays of individual songs across 25 European countries between the years 2011 to 2018, together with a multiattribute Spotify data set of songs and Hofstede’s cultural dimensions in relation to artist origins. We create pairs of similar artists who released a collaboration and a solo song in the same week and measure the impact of collaborations based on the difference-in-differences methodology. We find that releasing a collaboration song, in comparison with a solo song, increases the number of plays of an artist in the future by +4.6%. This lift can be broken down into +9.6% for the current song and +7.7% for subsequently released songs, whereas past songs are unaffected. The effect is moderated by the difference in economic, social, and cultural capitals and is significantly larger when one’s partner has higher economic and social capital or is highly dissimilar along the cultural dimension. Our theoretical and empirical exploration of such strategic alliances uncovers several underlying mechanisms at play in the success of these pairings and can serve as the basis for future work targeted at prescriptive contributions.

Accounts and Accountability: On Organizational Purpose, Organizational Identity, and Meaningful Work
Authors: Pratt Michael G. , Hedden Luke N. 
Published: March 2023

The recent rediscovery of corporate purpose has illuminated how much more we still need to understand about purpose and its role in organizations. After tracing the historical roots of purpose and conceptualizing its unique value in bridging the mundane and the moral in organizational life, we propose links among purpose and organizational identity, image and reputation, as well as with meaningful work. These linkages suggest two core functions of purpose: a vehicle for accountability (internal and external) and a source of accounts and justifications. These functions serve as mechanisms connecting purpose to different levels of analysis both within and outside of the organization. We also highlight potential impediments to maximizing the benefits of purpose: stakeholder cynicism and employee disillusionment. We conclude by suggesting new areas of research to overcome these impediments and to better establish purpose as a root construct in organizational scholarship. History: This paper has been accepted for the Strategy Science Special Issue on Corporate Purpose.
Joint precoding and power allocation in a FSO channel with signal-dependent noise
Authors: Feng Renhai , Kong Jingtian , Guo Xinchun , Wang Jiang , Xie Sheng 
Published: March 2023

To enhance the throughput of visible light communication (VLC), this
paper investigates precoding and power allocation jointly in a free
space optical channel with signal-dependent noise (SDN-FSO). With the
presence of SDN from a light source, a more realistic multi-user
multiple-input single-output (MU-MISO) VLC channel model is
introduced. First, based on the entropy power inequality, a capacity
bound for the SDN-FSO channel is derived under a MU-MISO scenario.
Second, due to the nonnegativity of SDN-FSO input, a zero forcing
constraint is introduced to alleviate multi-user interference. Third,
from the perspective of resource allocation, min-max and total power
budget constraints are taken into consideration. A non-convex joint
optimization problem is formulated and divided into two subproblems,
i.e., the precoding subproblem and power allocation subproblem.
Moreover, an iterative algorithm based on a concave and convex program
and a simplified high signal-to-noise ratio approximation method are
iteratively implemented in the precoding subproblem. For the power
allocation subproblem, successive convex approximation is employed to
ensure its optimality. Simulation results indicate that the proposed
joint optimization methods can converge after about two iterations and
accomplish a throughput improvement of up to 1∼3nats/s/Hz as compared with the benchmarks for
four different spacing scenarios. When channel state information is
interfered with noise, the proposed methods still demonstrate their
superior performance with varying degrees of noise.
Bewältigungsstrategien von Videoconference Fatigue
Authors: Bauer Victoria , Riedl René 
Published: March 2023

ZusammenfassungDie COVID-19 Pandemie veränderte global das Berufs- und Privatleben der Menschen und führte zu einer zunehmenden Nutzung von Digitaltechnologien, insbesondere von Videokonferenzsystemen (z. B. Zoom, Webex, Teams, Skype). Trotz der möglichen Vorteile dieser Systeme (z. B. Einsparung von Emissionen durch Reiseverzicht) wird in Wissenschaft und Praxis zunehmend über ein negatives Phänomen berichtet: Videoconference Fatigue (VCF) (synonym oft als Zoom Fatigue bezeichnet). Damit wird die Erschöpfung und Ermüdung beschrieben, die aus der Nutzung von Videokonferenzsystemen resultiert. Im vorliegenden Beitrag berichten wir über eine Analyse der Fachliteratur, deren Ziel es ist, den Stand der Forschung zu Bewältigungsstrategien zu dokumentieren. Die Analyse der Bewältigungsstrategien hilft, das Phänomen VCF besser zu verstehen sowie die Ermüdung und Erschöpfung zu verhindern bzw. zu reduzieren. Weiter sind die hier berichteten Ergebnisse eine Grundlage für zukünftige Arbeiten. Konkret haben wir mit Stand Mai 2022 48 wissenschaftliche Artikel zu VCF identifiziert, von denen sich 37 auch mit Bewältigungsstrategien befassen. Wir gliedern diese Strategien in organisatorische (z. B. Pausen während und zwischen Meetings), persönliche (z. B. Vermeidung von Multitasking) und technologische (z. B. Nutzung des „together mode“ in Teams) Maßnahmen. Ein wesentlicher Befund unserer Analyse ist zudem, dass die Wirksamkeit der Bewältigungsstrategien – mit einer Ausnahme – bislang nicht direkt empirisch untersucht und somit auch nicht nachgewiesen wurde. Dies eröffnet großes Forschungspotenzial für die Zukunft.

Published: March 2023

Background
Colombia is currently the world’s main recipient country for Venezuelan migrants, and women represent a high proportion of them. This article presents the first report of a cohort of Venezuelan migrant women entering Colombia through Cúcuta and its metropolitan area. The study aimed to describe the health status and access to healthcare services among Venezuelan migrant women in Colombia with irregular migration status, and to analyze changes in those conditions at a one-month follow-up.

Methods
We carried out a longitudinal cohort study of Venezuelan migrant women, 18 to 45 years, who entered Colombia with an irregular migration status. Study participants were recruited in Cúcuta and its metropolitan area. At baseline, we administered a structured questionnaire including sociodemographic characteristics, migration history, health history, access to health services, sexual and reproductive health, practice of early detection of cervical cancer and breast cancer, food insecurity, and depressive symptoms. The women were again contacted by phone one month later, between March and July 2021, and a second questionnaire was applied.

Results
A total of 2,298 women were included in the baseline measurement and 56.4% could be contacted again at the one-month follow-up. At the baseline, 23.0% of the participants reported a self-perceived health problem or condition in the past month and 29.5% in the past 6 months, and 14.5% evaluated their health as fair or poor. A significant increase was found in the percentage of women who reported a self-perceived health problem during the past month (from 23.1% to 31.4%; p<0.01); as well as in the share who reported moderate, severe, or extreme difficulty working or performing daily chores (from 5.5% to 11.0%; p = 0.03) and who rated their health as fair (from 13.0% to 31.2%; p<0.01). Meanwhile, the percentage of women with depressive symptoms decreased from 80.5% to 71.2% (p<0.01).

Conclusion
This report presents initial information on the health status of Venezuelan migrant women in Colombia, and is a starting point for further longer longitudinal follow-ups to assess changes over time in health conditions.

Published: March 2023

Background
Determining a thyroid hormone cutoff value in pregnancy is challenging issue and several approaches have been introduced to optimize a utility function. We aimed to estimate the cutoff value of TSH using Bayesian method for prediction of preterm-birth.

Methods
This study was a secondary-analysis of the population-based data collected prospectively within the framework of the Tehran Thyroid and Pregnancy Study. A total of 1,538 pregnant women attending prenatal clinics.

Results
Using Bayesian method resulted a TSH-cutoff of (3.97mIU/L,95%CI:3.95–4.00) for distinguishing pregnant women at risk of preterm-birth. The cutoff was associated with acceptable positive predictive and negative predictive values (0.84,95% CI:0.80–0.88) and 0.92 (95%CI: 0.91–0.94), respectively). In women who were negative for thyroid peroxides antibody (TPOAb) with sufficient urinary iodine concentration (UIC), the TSH cutoff of 3.92 mIU/L(95%CI:3.70–4) had the highest predictive value; whereas in TPOAb positive women with insufficient UIC, the cutoff of 4.0 mIU/L(95%:CI 3.94–4) could better predict preterm birth. Cutoffs estimated in this study are close to the revised TSH value of 4.0mIU/L which is currently recommended by the American Thyroid Association.

Conclusion
Regardless of TPOAb status or iodine insufficiency, risk of preterm labor is increased in pregnant women with TSH value of > 3.92 mIU/L; these women may benefit from Levothyroxine (LT4) therapy for preventing preterm birth.
What are the modifiable factors of treatment burden and capacity among people with Parkinson’s disease and their caregivers: A qualitative study
Authors: Tan Qian Yue , Roberts Helen C. , Fraser Simon D. S. , Amar Khaled , Ibrahim Kinda 
Published: March 2023

BackgroundPeople with long-term conditions must complete many healthcare tasks such as take medications, attend appointments, and change their lifestyle. This treatment burden and ability to manage it (capacity) is not well-researched in Parkinson’s disease.ObjectiveTo explore and identify potentially modifiable factors contributing to treatment burden and capacity in people with Parkinson’s disease and caregivers.MethodsSemi-structured interviews with nine people with Parkinson’s disease and eight caregivers recruited from Parkinson’s disease clinics in England (ages 59–84 years, duration of Parkinson’s disease diagnosis 1–17 years, Hoehn and Yahr (severity of Parkinson’s disease) stages 1–4) were conducted. Interviews were recorded and analyzed thematically.ResultsFour themes of treatment burden with modifiable factors were identified: 1) Challenges with appointments and healthcare access: organizing appointments, seeking help and advice, interactions with healthcare professionals, and caregiver role during appointments; 2) Issues obtaining satisfactory information: sourcing and understanding information, and satisfaction with information provision; 3) Managing medications: getting prescriptions right, organizing polypharmacy, and autonomy to adjust treatments; and 4) Lifestyle changes: exercise, dietary changes, and financial expenses. Aspects of capacity included access to car and technology, health literacy, financial capacity, physical and mental ability, personal attributes and life circumstances, and support from social networks.ConclusionsThere are potentially modifiable factors of treatment burden including addressing the frequency of appointments, improving healthcare interactions and continuity of care, improving health literacy and information provision, and reducing polypharmacy. Some changes could be implemented at individual and system levels to reduce treatment burden for people with Parkinson’s and their caregivers. Recognition of these by healthcare professionals and adopting a patient-centered approach may improve health outcomes in Parkinson’s disease.
How do group workers respond to suicidal behavior? Experiences and perceptions of suicidal female adolescents residing in secure residential youth care in the Netherlands

Published: March 2023

Background
Adolescent suicidal behavior, including non-suicidal self-injury, is increasingly prevalent in Secure Residential Youth Care (SRYC) in the Netherlands. Group workers play a vital role in the well-being and functioning of adolescents in SRYC as they interact with adolescents on a daily basis. However, we have little understanding of how adolescents perceive group workers’ responses to suicidal behavior and we lack knowledge about the impact of these responses on adolescents and the group climate.

Aim
The aim of this study is to explore (a) how adolescents value group workers responses towards suicidal behavior and (b) the impact of these responses on adolescents, as well as (c) on the group climate. The results can be used to develop care-policy to improve care for suicidal adolescents in SYRC.

Method
Eleven suicidal female adolescents residing in SRYC were interviewed. All adolescents had previously displayed suicidal behavior, including non-suicidal self-injury. Interviews were analyzed using grounded theory.

Conclusion
This study presents the perceptions of suicidal female adolescents residing in SRYC about group workers’ responses on suicidal behavior. Adolescents prefer group workers who react responsive to suicidal behavior. Responsive care, trust and connectedness help adolescents disclose their suicidal thoughts. Participants criticize group workers who are non-responsive as being distant, and their relationship with these group workers lacked trust, communication, a sense of connection, or personal depth. All adolescents underline the devastating impact of involuntary seclusion, and stress the importance of being able to disclose without fear of coercive consequences. Findings indicate that non-responsive reactions contribute to an increase in suicidal distress as well as a closed group climate.
Ending the HIV epidemic PrEP equity recommendations from a rapid ethnographic assessment of multilevel PrEP use determinants among young Black gay and bisexual men in Atlanta, GA
Authors: Hill Miranda , Smith Justin , Elimam Dena , Mustafaa Genetha , Wortley Pascale , Taylor Brittany , Harris Orlando 
Published: March 2023

Background
Efforts to mitigate HIV transmission among gay and bisexual men have not been sufficient to level persistent racial inequities which now extend to the use of daily oral pre-exposure prophylaxis (PrEP) for HIV prevention. Community-involved ethnographic research is crucial to galvanizing collaboration between patients, researchers, and policymakers to identify the social determinants of emerging PrEP inequities. In partnership with community key informants, we conducted a Rapid Ethnographic Assessment (REA) of multilevel PrEP use determinants among young Black gay and bisexual (YBGBM) men in the metropolitan Atlanta area to inform the development and coordination of local HIV programs.

Methods
In the assessment, we drew upon the perspectives of local clinicians, community-based organization leaders, health educators, and PrEP clients to identify barriers and facilitators to PrEP use among YBGBM through interviews (N = 23). Data were collected from September 2020 –to January 2021 and were analyzed through a staged deductive-inductive thematic analysis. The themes were later summarized and presented to community stakeholder participants to facilitate member-checking.

Results
Our analyses revealed structural, cultural, relationship, and developmental factors which shaped PrEP use. The most prominent being “ease of access to PrEP” (structural level), “provider support” (interpersonal), and “life-stage traits” (individual). Our results also contribute novel information concerning the axes of intersectional stigma (spatial, racial, sexual identity, and HIV) among YBGBM in Atlanta and its divergent effects on PrEP use.

Conclusion
Increased PrEP use among YBGBM, particularly among those living in the south, is essential to ending the domestic HIV epidemic. Altogether, our results emphasize the need for PrEP program modifications, which increase flexibility in methods and modes of access and are culturally adapted to the needs of YBGBM. There is also a need for resources that holistically focus on mental health, trauma, and racism as critical components of support.

Published: March 2023

AbstractThis study aims to investigate the impact of different facets of corruption on domestic investment (DI) in the Middle East and North Africa (MENA) economies. The main purpose of this empirical research to assess the influence of bribes, abuse of public office and nepotism on domestic investment in 14 MENA countries over the period 2005–2022. The results of 2SLS model indicate that corruption could affect negatively on domestic investments through two channels, namely: illegal payments (bribes) and the abuse of public office for private gain. In this case, the regulators and decision makers have to formulate new strategies that aimed particularly to fight these kinds of corruption to increase domestic investment.

Dispersion braiding and band knots in plasmonic arrays with broken symmetries
Authors: Yin Shixiong , Alù Andrea 
Published: March 2023

Abstract
Periodic arrays can support highly nontrivial modal dispersion, stemming from the interplay between localized resonances of the array elements and distributed resonances supported by the lattice. Recently, intentional defects in the periodicity, i.e., broken in situ symmetries, have been attracting significant attention as a powerful degree of freedom for dispersion control. Here we explore highly nontrivial dispersion features in the resonant response of linear arrays of plasmonic particles, including the emergence of braiding and band knots caused by band folding. We show that these phenomena can be achieved within simple dipolar arrays for which we can derive closed-form expressions for the dispersion relation. These phenomena showcase powerful opportunities stemming from broken symmetries for extreme dispersion engineering, with a wide range of applications, from plasma physics to topological wave phenomena. Our theoretical model can also be generalized to higher dimensions to explore higher-order symmetries, e.g., glide symmetry and quasi-periodicity.
