Social response to population change and migration: the impact of population change on individuals and institutions

Population change over the last 40 years has greatly redistributed Midwest populations. Migration has long been a social response to change—both to changing capacities in the agricultural system and to socio-cultural attractions and opportunities in the urban-industrial areas. Some of the surplus agricultural population has moved to cities and suburbs. The result is a selective dismembering of many communities and an inordinate growth of others.https://lib.dr.iastate.edu/specialreports/1037/thumbnail.jp

The distinctiveness of employment relations within multinationals: political games and social compromises within multinationals’ subsidiaries in Germany and Belgium

This work makes a theoretical contribution to our understanding of the strategic mechanisms that enable subsidiary management and union agency to exploit ambiguities in the subnational competitive context impacting labour flexibility-security concerns. In so doing, the article contributes to the distinctiveness of employment relations through scrutiny of the internal regime competition that fosters political games in MNCs. Studying the dynamics, we identify the set of structuring conditions governing political games, and explain why some workplace regimes generate social compromises whilst others do not. We reveal a set of strategic conditions (i.e. technology, embeddedness and MNC control) upon which compromise is built in six German and Belgian subsidiaries of four MNCs. Our analysis suggests that subsidiary control modes through expatriates and local embeddedness act as key mechanisms through which the effects of wider strategic drivers influence the form of social compromise

Hospitality entrepreneurs managing quality of life and business growth

The hospitality industry is dominated by small- and medium-sized enterprises (SMEs).They are often led by entrepreneurs who face the challenge of simultaneously managing business decisions and their own wellbeing. The competitiveness of tourism destinations often depends on these entrepreneurs and therefore understanding their motivations and work patterns is critical. Research on individual wellbeing increasingly builds on the concept of quality of life (QoL). Hospitality and tourism literature so far predominantly focused on investigating QoL for tourists and residents, rather than for entrepreneurs’ QoL, even though being key stakeholders in the hospitality industry. Therefore, this study explores the factors influencing hospitality entrepreneurs’ quality of life (“HE-QoL”) and how these relate to business growth. Results of a 380 hospitality entrepreneurs’ survey identify six distinct factors of HE-QoL. Two groups of HE-QoL are identified with significant differences in fitness level activity, entrepreneurial competencies and business growth. Findings lead to recommendations to reduce stress to improve HE-QoL, and to develop entrepreneurial competencies, which help to cope with entrepreneurial challenges. Tourism destinations and politics can support hospitality entrepreneurs in these actions by creating conditions that foster social exchange in regional communities and trust in political and economic stability

Flexible Usage and Interconnectivity of Diverse Cell Death Pathways Protect against Intracellular Infection.

Programmed cell death contributes to host defense against pathogens. To investigate the relative importance of pyroptosis, necroptosis, and apoptosis during Salmonella infection, we infected mice and macrophages deficient for diverse combinations of caspases-1, -11, -12, and -8 and receptor interacting serine/threonine kinase 3 (RIPK3). Loss of pyroptosis, caspase-8-driven apoptosis, or necroptosis had minor impact on Salmonella control. However, combined deficiency of these cell death pathways caused loss of bacterial control in mice and their macrophages, demonstrating that host defense can employ varying components of several cell death pathways to limit intracellular infections. This flexible use of distinct cell death pathways involved extensive cross-talk between initiators and effectors of pyroptosis and apoptosis, where initiator caspases-1 and -8 also functioned as executioners when all known effectors of cell death were absent. These findings uncover a highly coordinated and flexible cell death system with in-built fail-safe processes that protect the host from intracellular infections.Wellcome Trus

MARK4 controls ischaemic heart failure through microtubule detyrosination.

Myocardial infarction is a major cause of premature death in adults. Compromised cardiac function after myocardial infarction leads to chronic heart failure with systemic health complications and a high mortality rate1. Effective therapeutic strategies are needed to improve the recovery of cardiac function after myocardial infarction. More specifically, there is a major unmet need for a new class of drugs that can improve cardiomyocyte contractility, because inotropic therapies that are currently available have been associated with high morbidity and mortality in patients with systolic heart failure2,3 or have shown a very modest reduction of risk of heart failure4. Microtubule detyrosination is emerging as an important mechanism for the regulation of cardiomyocyte contractility5. Here we show that deficiency of microtubule-affinity regulating kinase 4 (MARK4) substantially limits the reduction in the left ventricular ejection fraction after acute myocardial infarction in mice, without affecting infarct size or cardiac remodelling. Mechanistically, we provide evidence that MARK4 regulates cardiomyocyte contractility by promoting phosphorylation of microtubule-associated protein 4 (MAP4), which facilitates the access of vasohibin 2 (VASH2)-a tubulin carboxypeptidase-to microtubules for the detyrosination of α-tubulin. Our results show how the detyrosination of microtubules in cardiomyocytes is finely tuned by MARK4 to regulate cardiac inotropy, and identify MARK4 as a promising therapeutic target for improving cardiac function after myocardial infarction.BHF fellowship grant (FS/14/28/30713), Issac Newton Trust Grant (18.40u), and Cambridge BHF Centre of Research Excellence grants (RE/13/6/30180 and RE/18/1/34212)

The Moral Duty of Self-Preservation

UIDB/00183/2020 UIDP/00183/2020This chapter provides an in-depth examination of Kant’s view of suicide. After a contextualization of Kant’s prohibition of suicide (§2.1), seven different arguments against the moral permissibility of suicide are identified: three from the Lectures on Ethics (§2.2) and four from the published writings (§2.3). Each argument is presented (with possible variations) and explained. Strengths and flaws are pointed out, and possible objections and counter-objections are discussed, taking into consideration the abundant bibliography on the subject. The conclusion is that, against a recent trend in secondary literature, which tends to read Kant as justifying not only a right, but even a duty to suicide, Kant does not allow for any exception to his strict prohibition of suicide.authorsversionpublishe

The interaction between vaginal microbiota, cervical length, and vaginal progesterone treatment for preterm birth risk

© The Author(s) 2017. Background: Preterm birth is the primary cause of infant death worldwide. A short cervix in the second trimester of pregnancy is a risk factor for preterm birth. In specific patient cohorts, vaginal progesterone reduces this risk. Using 16S rRNA gene sequencing, we undertook a prospective study in women at risk of preterm birth (n = 161) to assess (1) the relationship between vaginal microbiota and cervical length in the second trimester and preterm birth risk and (2) the impact of vaginal progesterone on vaginal bacterial communities in women with a short cervix. Results: Lactobacillus iners dominance at 16 weeks of gestation was significantly associated with both a short cervix < 25 mm (n = 15, P < 0.05) and preterm birth < 34+0 weeks (n = 18; P < 0.01; 69% PPV). In contrast, Lactobacillus crispatus dominance was highly predictive of term birth (n = 127, 98% PPV). Cervical shortening and preterm birth were not associated with vaginal dysbiosis. A longitudinal characterization of vaginal microbiota (< 18, 22, 28, and 34 weeks) was then undertaken in women receiving vaginal progesterone (400 mg/OD, n = 25) versus controls (n = 42). Progesterone did not alter vaginal bacterial community structure nor reduce L. iners-associated preterm birth (< 34 weeks). Conclusions: L. iners dominance of the vaginal microbiota at 16 weeks of gestation is a risk factor for preterm birth, whereas L. crispatus dominance is protective against preterm birth. Vaginal progesterone does not appear to impact the pregnancy vaginal microbiota. Patients and clinicians who may be concerned about "infection risk" associated with the use of a vaginal pessary during high-risk pregnancy can be reassured

The BARRIERS scale -- the barriers to research utilization scale: A systematic review

<p>Abstract</p> <p>Background</p> <p>A commonly recommended strategy for increasing research use in clinical practice is to identify barriers to change and then tailor interventions to overcome the identified barriers. In nursing, the BARRIERS scale has been used extensively to identify barriers to research utilization.</p> <p>Aim and objectives</p> <p>The aim of this systematic review was to examine the state of knowledge resulting from use of the BARRIERS scale and to make recommendations about future use of the scale. The following objectives were addressed: To examine how the scale has been modified, to examine its psychometric properties, to determine the main barriers (and whether they varied over time and geographic locations), and to identify associations between nurses' reported barriers and reported research use.</p> <p>Methods</p> <p>Medline (1991 to September 2009) and CINHAL (1991 to September 2009) were searched for published research, and ProQuest^®digital dissertations were searched for unpublished dissertations using the BARRIERS scale. Inclusion criteria were: studies using the BARRIERS scale in its entirety and where the sample was nurses. Two authors independently assessed the study quality and extracted the data. Descriptive and inferential statistics were used.</p> <p>Results</p> <p>Sixty-three studies were included, with most using a cross-sectional design. Not one study used the scale for tailoring interventions to overcome identified barriers. The main barriers reported were related to the setting, and the presentation of research findings. Overall, identified barriers were consistent over time and across geographic locations, despite varying sample size, response rate, study setting, and assessment of study quality. Few studies reported associations between reported research use and perceptions of barriers to research utilization.</p> <p>Conclusions</p> <p>The BARRIERS scale is a nonspecific tool for identifying general barriers to research utilization. The scale is reliable as reflected in assessments of internal consistency. The validity of the scale, however, is doubtful. There is no evidence that it is a useful tool for planning implementation interventions. We recommend that no further descriptive studies using the BARRIERS scale be undertaken. Barriers need to be measured specific to the particular context of implementation and the intended evidence to be implemented.</p
