Abstract A further growth in the Norwegian aquaculture industry might potentially be hampered by the conclusion that it is not environmentally sustainable. As direct measurements of the lice induced mortality on wild salmonids are impossible, the management is based on a set of high-quality and well-documented sustainability indicators. These indicators combine observations from the national Norwegian salmon lice monitoring programme with salmon lice models. Here, we have documented the quality of one of these models used to identify areas where the impact from farmed to wild salmonids is over the prescribed limit. The Hardangerfjord area has been used as a test area, but the model is general and, therefore, suitable for the rest of the coast. It is shown that the model system is robust and also can be used to test whether new knowledge gained from laboratory experiments improves the model. New findings on salmon lice behaviour at low salinities have been incorporated and the new model, consisting of a high-resolution hydrodynamic model coupled with an individual-based salmon lice model and forced with realistic input of salmon lice larvae from aquaculture farms, represents the best realization of the local potential infestation pressure on wild fish.

Abstract Nursing homes (NHs) faced an unprecedented crisis during the rapid spread of COVID-19. This pandemic has had a devastating impact on both NH residents and workers who are often on the frontlines providing hands-on care. These workers are vulnerable to the health risks of COVID-19 due to daily exposure to residents with COVID-19, residence in areas with high infection rates, and challenges specific to low-income workers (e.g. reliance on mass transportation). Research has highlighted the experiences of NH workers during the pandemic to learn how to better support them now and during future pandemics. This symposium will add to this research and present new findings from studies conducted in the United States to capture the unique experiences of NH employees. First, Bryant illustrates specific COVID-19-related challenges that NH frontline workers faced and how these workers’ experiences compare to workers in other long-term services and support settings. Reinhardt reports findings from a qualitative study examining the multi-level challenges experienced by nursing assistants during the pandemic. Cimarolli examines if quality of employer communication and workers’ perceived COVID-19-related preparedness mitigate the impact of work-related stress on NH workers’ decision to resign. Franzosa shares recommendations based on priorities identified by nursing assistants and administrators to build future resilience based on lessons learned. Finally, Simpson identifies factors associated with states’ decisions to adopt COVID-19 testing mandates for workers in NHs. Dr. Zimmerman discusses study findings and their contributions for creating supportive NH work environments to ensure most optimal NH worker and resident quality of life.

Abstract Due to the increased tendency to use private transport in urban areas of Manizales and Villamaría municipalities, it is intended to include alternative modes of transport that are more time-efficient and environmentally sustainable to improve the inhabitants’ quality of life. This article aims to analyse the inclusion impact of a sustainable public transport system, such as a new cableway line in the city connecting the Central Business District (CBD) with Ciudadela del Norte district, measuring overall average accessibility for the current and future scenario. This establishes the average travel time and the savings in terms of time shown as a percentage that these modes of transport would create in the population displacement and also which inhabitants are the most likely to benefit.

Based on the global debate on the development of executive pay as well as the lack of transparent information that has prompted the implementation of far-reaching legal reforms, this paper aims to determine the quality of voluntary remuneration reporting of top management in Germany. To investigate the impact of ownership and remuneration structure on voluntary remuneration reporting, an OLS regression analysis is used. To assess the quality of remuneration reporting, we calculate a total score for 160 listed companies on the basis of a scoring model derived from four criteria. The criteria are individualized remuneration disclosure, use of the German Corporate Governance Code model table, information on the say-on-pay vote and on the role of the compensation consultant. This study comes to the result that reporting quality in Germany differs heavily and depends on ownership and remuneration structure. On the one hand, a high share of fixed remuneration shows a significant negative and the existence of family shareholders a simple negative impact on reporting quality. In contrast to this, a high percentage of the free float as well as highly variable compensation influence voluntary remuneration reporting in a positive way. Simultaneously, the company’s performance correlates significant negative while company size and leverage ratio show no effect at all. This paper extends upon prior research that has identified determinants of the voluntary individual disclosure of management remuneration in Germany (Andres and Theissen, 2007; Chizema, 2008). The new findings of this paper partly differ from former research and help to derive statements that are more current, comprehensive and go beyond the results of the previous studies. Furthermore, the insights offer implications for firms, theory, and new opportunities regarding future empirical research.

Purpose The purpose of this study was to identify levels of self-compassion in adults who do and do not stutter and to determine whether self-compassion predicts the impact of stuttering on quality of life in adults who stutter. Method Participants included 140 adults who do and do not stutter matched for age and gender. All participants completed the Self-Compassion Scale. Adults who stutter also completed the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed for self-compassion differences between and within adults who do and do not stutter and to predict self-compassion on quality of life in adults who stutter. Results Adults who do and do not stutter exhibited no significant differences in total self-compassion, regardless of participant gender. A simple linear regression of the total self-compassion score and total Overall Assessment of the Speaker's Experience of Stuttering score showed a significant, negative linear relationship of self-compassion predicting the impact of stuttering on quality of life. Conclusions Data suggest that higher levels of self-kindness, mindfulness, and social connectedness (i.e., self-compassion) are related to reduced negative reactions to stuttering, an increased participation in daily communication situations, and an improved overall quality of life. Future research should replicate current findings and identify moderators of the self-compassion–quality of life relationship.

Lung cancer is one of the most commonly diagnosed cancers across Northern America and Europe. Treatment options offered are dependent on the type of cancer, the location of the tumor, the staging, and the overall health of the person. When surgery for lung cancer is offered, difficulty swallowing is a potential complication that can have several influencing factors. Surgical interaction with the recurrent laryngeal nerve (RLN) can lead to unilateral vocal cord palsy, altering swallow function and safety. Understanding whether the RLN has been preserved, damaged, or sacrificed is integral to understanding the effect on the swallow and the subsequent treatment options available. There is also the risk of post-surgical reduction of physiological reserve, which can reduce the strength and function of the swallow in addition to any surgery specific complications. As lung cancer has a limited prognosis, the clinician must also factor in the palliative phase, as this can further increase the burden of an already compromised swallow. By understanding the surgery and the implications this may have for the swallow, there is the potential to reduce the impact of post-surgical complications and so improve quality of life (QOL) for people with lung cancer.
