Jellyfish are known to carry various epibionts, including many of the subphylum Crustacea. However, the associations between gelatinous zooplankton and other invertebrates have been chronically overlooked. Crustacea, a massive clade of economically, ecologically, and culturally important species, includes many taxa that utilize gelatinous zooplankton for food, transport, and protection as both adults and juveniles. Here we compile 211 instances of epifaunal crustaceans recorded on Hydromedusae and Scyphomedusae from a century of literature. These include 78 identified crustacean species in 65 genera across nine orders found upon 37 Hydromedusa species and 48 Scyphomedusae. The crustacean life stage, location, nature of the association with the medusa, years, months, and depths are compiled to form a comprehensive view of the current state of the literature. Additionally, this review highlights areas where the current literature is lacking, particularly noting our poor understanding of the relationships between juvenile crabs of commercially valuable species and medusae.

✓In an effort to help clarify the current state of medical therapy for cerebral vasospasm, the authors reviewed the relevant literature on the established medical therapies used for cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH), and they discuss burgeoning areas of investigation. Despite advances in the treatment of aneurysmal SAH, cerebral vasospasm remains a common complication and has been correlated with a 1.5- to threefold increase in death during the first 2 weeks after hemorrhage. A number of medical, pharmacological, and surgical therapies are currently in use or being investigated in an attempt to reverse cerebral vasospasm, but only a few have proven to be useful. Although much has been elucidated regarding its pathophysiology, the treatment of cerebral vasospasm remains a dilemma. Although a poor understanding of SAH-induced cerebral vasospasm pathophysiology has, to date, hampered the development of therapeutic interventions, current research efforts promise the eventual production of new medical therapies.

Fueled by socioeconomic trends that changed the composition of organizational workforces, the term workforce diversity was coined in the 1990s. Since then, both researchers and practitioners have strived (and struggled) to understand the concept, its effects in and on organizations, and strategies for managing such effects. In this article, I provide an overview and interpretation of the current literature to examine its purpose, progress, and direction. Highlighting key conceptualizations of the construct, theoretical foundations, and empirical findings on diversity and diversity management, I discuss the evolution and current state of the field and synthesize this information to propose a future research agenda. In doing so, I seek to identify theoretical, empirical, and practice areas of opportunity for advancing scientific knowledge about the meaning, substance, and outcomes of diversity as well as the implementation of diversity science in organizations.

The transfer of anesthesia patient information within a perioperative setting is susceptible to many barriers that prevent effective communication. Several studies have aimed to combat these barriers by successfully developing and implementing structured communication protocols. The purpose of this review is to provide a synthesis of the current state of literature in order to guide practice and future research into the development, implementation, and evaluation of anesthesia patient handoff protocols. Four databases were searched based on inclusion criteria, resulting in 33 studies that were reviewed for this analysis. Results show there are many methods used in current literature to design, implement, and evaluate anesthesia handoff protocols, suggesting little consensus for best practice. Future handoff studies should ensure they fully report all details associated with the development and evaluation of their anesthesia handoff protocols to promote replicability and guidance for other practitioners.

Purpose There are countless factors that affect where an entrepreneur chooses to open a business that have been studied in the literature, including local socio-economic conditions, government policy, and agglomeration economies. One important aspect to the location decision that has not received as much attention from researchers thus far is the impact of crime on entrepreneurship. The purpose of this paper is to discuss the current literature on this topic, with a particular emphasis on the empirical issues present that have likely caused the research in this area to be scarce. Design/methodology/approach The authors conduct an analysis of the current state of the literature examining the relationship between crime and entrepreneurship. Looking at what has been done in the past, as well as improvements in the data, the authors discuss what has been done and what can be done in the future. Findings The authors discuss areas related to entrepreneurship and crime that the authors see as an emerging literature, based largely on the improvements in data and identification strategies that allow the authors to answer questions that the authors previously could not. Originality/value This paper is a review of the current literature, which also discusses areas that future researchers should consider and analyze further.

The current operational environment for organizations is changing, which has effects on IT functions and IT activities. Various forms of networks, collaborations, and alliances are operational models, which organizations are using to an increasing extent. This reality has brought with it a need for improved IT governance (ITG). ITG research for inter-organizational arrangements will be needed. In the research, the target is to identify the current state of the inter-organizational ITG research among the information systems (IS) domain. The literature review covers academic articles and conference proceedings during this millennium. The findings of the current literature review reveal that interest towards ITG research is still quite limited. The future view of inter-organizational ITG research is quite clear: more research will be needed in the inter-organizational area, which is the current playground for several organizations today.

Phytotechnologies are often shown as an emerging tool to remediate contaminated soils. Research in this field has resulted in many important findings relating to plant and soil sciences. However, there have been scant private and public investments and little commercial success with this technology. Here, we investigate the barriers to the adoption of phytotechnologies and determine whether it is still a fertile area for future research. The terminology used in phytotechnologies includes a confusing mish-mash of terms relating to concepts and processes increasing the difficulty of developing a unique commercial image. We argue that the commercial success of phytotechnologies depends on the generation of valuable biomass on contaminated land, rather than a pure remediation technique that may not compare favourably with the costs of inaction or alternative technologies. Valuable biomass includes timber, bioenergy, feedstock for pyrolosis, biofortified products, or ecologically important species.

Clovers (Trifoliumspecies) are a large and widespread genus of legumes. Recent work supports the Mediterranean origin of the genus in the Early Miocene period, and centres of diversity for clovers occur in the Eastern Mediterranean, East Africa and South America. A number of clovers are of agricultural importance as forage species in grassland agriculture around the world, particularly in temperate areas. White clover (Trifolium repensL.) is the most important legume of grazed pastures, and red clover (T. pratense) is widely cut and conserved as a winter feed. We consider the current state of collected resources in clovers, which have been collated in the most important databases. These are European Internet Search Catalogue (EURISCO), germplasm resources information network and system-wide information network for genetic resources together with the collection held at AgResearch, New Zealand. In total, collections have been made of 204 species with 48 species having more than 100 accessions in these databases. As expected, the majority of accessions are of the agriculturally important species. The geographical origin of collected material is outlined and, for the major species, accessions are broken down according to their status, e.g. wild population, breeders' lines. We then describe some of the ways in which genetic resources of white and red clovers and their relatives have been used in the breeding of these species. These include introgression of stress tolerance traits, targetting improvements in resource use efficiency and increasing seed yield.

The ever-increasing pace of development, experienced in all aspects of life, has become a major factor of our times. Public administration is no exception to this tendency. I have chosen the government windows (and other miscellaneous administrative bodies operating alongside them) established in the past five years as the topic of my study exactly because of this – their development is expected to remain unbroken in the future as well. During my research, I paid special attention to past and current legal changes, aiming to provide a comprehensive view on the establishment, operation, and evolution of the integrated administration points in Hungary. My study also covers the current state and the expected developments of domestic e-Administration solutions. Finally, I also offer some conclusions and recommendations regarding the large-scale deployment of the planned single-window administrative system.

With the growth of online learning, the number of remote adjunct faculty has increased. Like their traditional counterparts, these faculty members need and benefit from professional development. However, remote faculty have distinct needs due to geographic separation, motivational differences, and being a part-time employee, often while holding another full-time job. This chapter reviews the current state of professional development offerings for remote faculty and the current literature on the needs and barriers faced by remote faculty. It also discusses this author's perception of barriers to and recommendations for remote faculty professional development and recommends best practices for delivering enriching opportunities for remote faculty.

This essay considers the current state of the pedagogical auditing literature using a theoretical lens proposed by philosopher and literary critic René Girard. In extant pedagogical auditing cases that are based on historical events, auditors are often portrayed as villains. Presently, there are few pedagogical cases in which auditors are depicted as heroes. Appending the current literature with real world illustrations and accounts of auditors behaving virtuously would help balance the literature and improve the classroom experience for students. Moreover, these positive accounts should be memorialized in the auditing profession's history.
