This paper aims to investigate the effect of L-citrulline supplementation on blood pressure (BP) in middle-aged and elderly populations.

Three electronic databases, namely, Google Scholar, PubMed and Scopus, were searched from 1990 to November 2020. Random effects model analysis was applied for quantitative data synthesis, and 6 trials with 150 participants were identified and included in the analysis.

Results showed an overall non-significant effect of L-citrulline supplementation on both systolic BP (SBP) and diastolic BP (DBP) in middle-aged and elderly participants. However, stratified analysis indicated a significant reduction in SBP (SMD: −0.41, 95% CI: −0.84, 0.02; p = 0.06, heterogeneity p = 0.41; I2 = 10%) but not in DBP (SMD:−0.15, 95% CI: −0.57, 0.28; p = 0.51, heterogeneity p = 0.60; I2 = 0%), following longer-term (= 8 weeks) supplementation of L-citrulline. Additionally, higher doses of L-citrulline (= 6 grams) showed a marginally significant reduction in DBP (SMD: −0.38, 95% CI: −0.78, 0.02; p = 0.06, heterogeneity p = 0.50; I2 = 0%).

In conclusion, a higher dosage and longer duration of supplementation with L-citrulline may have potential BP lowering effects in populations at an increased risk of hypertension

While the literature has focused on the benefits granted by Deferred Action for Childhood Arrivals to undocumented youths in the USA, the purpose of this paper is to focus on the challenges encountered during the application process.

This paper is based on 60 semi-structured interviews with Latino undocumented youths living in the New York City and northern New Jersey metropolitan area.

The policy was intended to improve the inclusion of some undocumented youths in the USA by temporarily shielding them from deportation and providing them with a social security number. Analyses indicate great variation in youths’ experiences while applying for DACA, including program knowledge, financial impact, and application assistance – some of which was alleviated by respondents’ political engagement. This paper shows that participants suffered from anxiety due to the manner of implementation of the program.

This research is based on the self-disclosure of participants as undocumented youths. Fieldwork also took place in the New York/New Jersey metropolitan area, which is traditionally considered as more “immigrant-friendly” context than other areas of the USA.

This paper provides much needed information on the ways in which undocumented youths navigate the federal immigration system and the anxiety associated with it. This paper demonstrates the possibility that a federal policy whose goal is inclusionary could be implemented at the local level in such a way as to promote anxiety and alienation. It also highlights the role of political engagement in shaping immigrant youth’s experiences in the USA.

This article aims to provide a theoretical unifying framework for flexible organizational forms, such as so-called adhocracies and network organizations.

In this article, organization practices that are typical of the software industry are analyzed and re-interpreted by means of foundational concepts of organization science. It is shown that one and the same logic is at work in all flexible organizations.

Coordination modes can be fruitfully employed to characterize flexible organizations. In particular, standardization is key in order to obtain flexibility, provided that a novel sort of coordination by standardization is added to those that have been conceptualized hitherto.

This article highlights one necessary condition for organizations to be flexible. Further aspects, only cursorily mentioned in this paper, need to be addressed in order to obtain a complete picture.

A theory of organizational flexibility constitutes a guide for organizational design. This article suggests the non-obvious prescription that the boundary conditions of individual behavior must be standardized in order to achieve operational flexibility.

This theoretical framework can be profitably employed in management classes.

Currently, flexible organizations are only understood in terms of lists of instances. This article shows that apparently heterogeneous case-studies share common features in fact.

The purpose of this paper is to empirically examine the relationship between psychological diversity climate (PDC) and organizational identification (OID) when influenced by racial dissimilarity between the subordinate and supervisor.

Ordinary least squares hierarchical regression analysis was run for hypotheses testing.

Three of the four hypothesized relationships were supported. Support was found for the direct relationship between PDC and OID. The moderator race was significant thus also supported. The moderator of dissimilarity was not supported. Finally the three-way interaction with race and dissimilarity was supported.

OID is an important variable for overall organizational success. OID influences a wealth of organizationally relevant outcomes including turnover intentions. Considering higher turnover exists for minority employees, understanding how diversity climate perceptions vary by employee race and therefore impact OID differently, helps managers when making decisions about various initiatives.

This study is the first the authors know of to investigate the impact of dissimilarity on the PDC-OID relationship.

The purpose of this paper is to understand several key issues regarding technology strategies for the lodging industry, including the use and impact of technology, technology adoption and implementation, the role of organization technology environment in technology use, channel management strategies, as well as future trends of technology development.

Qualitative interviews are conducted with hotel practitioners to gain knowledge in order to help explore issues and generate hypotheses for future research regarding information and communications technology (ICT) applications in the lodging industry.

The research finds that technology will continue to impact guest service and customer relationship management in the lodging industry, and that companies vary in their implementation and use of the technology applications.

Using qualitative research limited the number of hotels that could be interviewed; as a result, the findings cannot be generalized to every hotel.

Hotel owners and managers can look at the various trends and determine which can help their guest service, focusing on providing added value to guests.

The paper provides insight from the viewpoints of practitioners rather than just from technology experts.

This paper recovers some theoretical elements of the sociology of childhood in the Anglo-Saxon field, to discuss their contributions, scopes and limits about child agency in children living in poor and urban contexts, in Latin America. The objective is to contribute to the debates within the field of childhood from a sociological perspective that accentuate the capacity of action and resistance of children even in the framework of structural restrictions, without assuming a decontextualized and ideal approach about the agency.
