ABSTRACT The June sucker Chasmistes liorus is endemic to Utah Lake, Utah. Abundant when first described in the 19th century, the species declined precipitously in the 20th century, leading to it being listed as endangered in 1986. The wild population size at time of listing was estimated to be less than 1,000 and may be even smaller at present. A multi-partner cooperative program was formally established in 2002 with the dual goals of recovering the June sucker and allowing continued operation of water facilities for human use. One recovery action of the program has been collection and artificial propagation of June sucker, yielding more than 46,000 June sucker of varying ages currently being held outside of Utah Lake. Mature fish held in captivity are beginning to contribute to recovery as they and their offspring are released into the lake. Dwindling numbers of wild fish combined with the increasing proportions of stocked fish returning to spawn in the Provo River indicates barriers to recruitment that are being addressed by other program recovery actions. While actions being taken to address environmental threats to June sucker, especially controlling nonnative fishes and habitat alteration, must continue if artificially and naturally produced June sucker are to survive in Utah Lake, the ability of this species to thrive and reproduce in habitats outside of Utah Lake will likely be important to its persistence. Habitat recovery and conservation efforts will be critical for maintaining a diverse environment where both June sucker and Utah sucker Catostomus ardens can survive. Environmental influences in Utah Lake appear to have been important for the evolution of sucker feeding habits and the observed morphologies of the two species. June sucker have been kept from going extinct, but should remain listed as endangered. The goal of this paper is to present information regarding the current status of June sucker and the status of actions to recover this endangered species, currently dominated by the captive propagation efforts.

Sericulture involves the rearing of silk-producing insects in captivity or collecting their silk cocoons in the field for production offabrics. The majority of the world’s silk is mulberry obtained from the domesticated silkworm, Bombyx mori L. (Lepidoptera:Bombycidae). Sericulture was formally introduced into Ghana in 1992 leading to the establishment of the Silk FarmersAssociation, and later a silk factory in 2002 with support from the FAO. This boost led to an increase in raw cocoon production,but is now dwindling due to numerous challenges facing the silk industry. A survey was carried out in the Eastern, BrongAhafo and Northern Regions of Ghana to establish the current status of sericulture. The survey revealed that farmers aremostly engaged in mulberry sericulture with wild silk being minimal, restricted to the rearing of the Eri silkworm, Philosamiaricini (Donovan) (Lepidoptera: Saturniidae) on castor oil and cassava leaves. Another important wild silkmoth, Gonometa sp.(Lepidoptera: Lasiocampidae) was found on Acacia sp. in northern Ghana. Brong-Ahafo region had the highest number ofsilk farmers. Farmers’ participation in sericulture has decreased over the years as a result of many setbacks. The prospectsand challenges confronting the sericulture industry in Ghana are discussed.

Glass ionomer cements and resin-based composites are promising materials in restorative dentistry. However, their limited mechanical properties and the risk of bulk/marginal fracture compromise their lifespan. Intensive research has been conducted to understand and develop new materials that can mimic the functional behavior of the oral cavity. Nanotechnological approaches have emerged to treat oral infections and become a part of scaffolds for tissue regeneration. Carbon nanotubes are promising materials to create multifunctional platforms for dental applications. This review provides a comprehensive survey of and information on the status of this state-of-the-art technology and describes the development of glass ionomers reinforced with carbon nanotubes possessing improved mechanical properties. The applications of carbon nanotubes in drug delivery and tissue engineering for healing infections and lesions of the oral cavity are also described. The review concludes with a summary of the current status and presents a vision of future applications of carbon nanotubes in the practice of dentistry.

Institutional repositories are powerful tools to facilitate global access to intellectual output by members of the institution, particularly in assisting them to preserve and maximize access to their research output globally. This exploratory study of the status of institutional repositories implementation in African countries using the global Directory of Open Access Repositories (OpenDOAR) and Transparent Ranking: All Repositories by Google Scholar, reports on the operational status and the performance of repositories. Factor analysis and cluster analysis are used to analyze the operational level of institutional repositories in African countries. The analysis showed that the typical performance of institutional repositories remains below average. The possibility of global open access to research results through institutional repositories in South Africa, Kenya, Nigeria, Algeria, Sudan, and Egypt appeared to be relatively more feasible than other African countries. This study concludes that many organizations, institutions, and societies spend great efforts in support of open access implementation in Africa, however, the widespread implementation of institutional repositories is still very slow paced, and the performance of the implemented repositories was below expectation. Suggestions for regaining the intended direction of African institutional repositories are given based on the current status.

Purpose – Recent literature emphasizes the application of lean manufacturing practices to food processing industries in order to improve operational efficiency and productivity. Only a very limited number of studies have focused on the implementation of lean manufacturing practices within small and medium-sized enterprises (SMEs) operating in the food sector. The majority of these studies used the case study method and concentrated on individual lean manufacturing techniques geared towards resolving efficiency issues. This paper aims to analyze the status of the lean manufacturing practices and their benefits and barriers among European food processing SMEs. Design/methodology/approach – A structured questionnaire was developed to collect data. A total of 35 SMEs' representatives, mostly CEOs and operations managers, participated in the survey. The study investigated the role of two control variables in lean implementation: size of the company and country of origin. Findings – The findings show that lean manufacturing practice deployment in food processing SMEs is generally low and still evolving. However, some lean manufacturing practices are more prevalent than others; e.g. flow, pull and statistical process control are not widely used by the food processing SMEs, whereas total productive maintenance, employee involvement, and customer association are more widespread. The key barriers encountered by food SMEs in the implementation of lean manufacturing practices result from the special characteristics of the food sector, such as highly perishable products, complicated processing, extremely variable raw materials, recipes and unpredictable demand. In addition, lack of knowledge and resources makes it difficult for food processing SMEs to embark on the lean journey. Originality/value – The gap in the literature regarding the application of lean manufacturing in the food sector is identified and addressed in this study. The originality of this paper lies in analyzing the current status of the use of lean manufacturing practices among food SMEs in Europe and identifying potential barriers.

The Status

The members of the profession of audiology often express concern that the services and products that have been developed to provide benefit to the hearing impaired are not sought after or delivered to the majority of those diagnosed with hearing loss. A critical look at the status quo of hearing care delivery in the United States is needed to verify this assumption and to develop strategies to improve the situation. A key concern is the lack of a comprehensive high-quality scientific database upon which to build continuous improvements in the effectiveness of the services and products that are provided to the hearing impaired.

Changes Over Time

The article examines the dynamics of social status self-evaluations of the Ukrainians based on two waves (2009 and 2019) of the Social Inequality module of International Social Survey Programme. Three types of social status self-evaluation in different biographical situations were noted: the current one (at the time of the survey), the retrospective one (of the parents’ family status) and the perspective one (status of oneself in 10 years’ time). They were measured through the respondents’ self-determination of their appropriate status on an imaginary 10-step social ladder. The noticeable changes for the better in the current social status self-evaluations of the Ukrainians are stated, which is visualized in changing the diagram of their distribution from pyramidal shape (where the lower-middle and the lowest positions are the basic ones) to the close to rhombus shape (where the majority is concentrated on the middle levels). The retrospective self-evaluations still demonstrate negative situation: the respondents mostly perceive the social status of parents’ families as higher than their current status. At the same time, the perspective self-evaluations of the Ukrainians are rather optimistic: majority of them hope to significantly increase their own status in the social hierarchy in the next decade. A connection between the class positions (both objectively and subjectively determined) and the status self-evaluations of three kinds was also studied. It is recorded that in both years of the survey this connection remains quite significant and expected in nature. Regarding EGP-classes: representatives of service classes and small owners had significantly higher current, retrospective and prospective self-evaluations than working-class people, primarily unskilled workers and farm labours. Regarding the subjective classes defined by nominal categories (upper middle, middle, lower middle, working, lower class): the higher the subjective class position a person has, the higher he/she evaluates his/her social status.

Context Monitoring populations of long-lived species requires continuous long-term efforts. This is especially applicable for species that have experienced declines range-wide. Aims Our study assessed the current status of a population of wild Macrochelys temminckii and compared the present results to those from a survey conducted nearly a decade ago. Methods Trapping in 2010–2011 was conducted on two creeks within the refuge, during the months of May–July. Capture data were compared with data collected by similar methods in 1997–2001. Key results The population structure of M. temminckii was dominated by juveniles, with few large adults or small juveniles detected and a missing size class was evident. Retrospective analysis of 1997–2001 data revealed that the population was likely to be in decline even then, despite high capture rates. Conclusions The M. temminckii population showed significant declines that indicated that the population had experienced stressors of unknown origin. The status of M. temminckii at the refuge is concerning, given the protection afforded this remnant population. Implications Short-term data from 1997–2001 indicated a healthy M. temminckii population, whereas longer-term data showed that the population has declined, resulting in significant demographic changes. Continued monitoring will be necessary to develop management recommendations and track the impact of implemented management practices. Longer-term monitoring of long-lived vertebrates is required to identify population trends.

AbstractMultiple myeloma (MM) is a treatable plasma cell cancer with no cure. Clinical evidence shows that the status of minimal residual disease (MRD) after treatment is an independent prognostic factor of MM. MRD indicates the depth of post-therapeutic remission. In this review article, we outlined the major clinical trials that have determined the prognostic value of MRD in MM. We also reviewed different methods that were used for MM MRD assessment. Most important, we reviewed our current understanding of MM MRD biology. MRD studies strongly indicate that MRD is not a uniform declination of whole MM tumor population. Rather, MM MRD exhibits unique signatures of cytogenetic aberration and gene expression profiles, unlike those of MM cells before therapy. Diagnostic high-risk MM and low-risk MM exhibited a diversity of MRD features. Clonal evaluation may occur at the MRD stage in MM. The dynamics from the diagnostic MM to MRD correlate with the disease prognosis. Lastly, on the aspect of omics, we performed data-based analysis to address the biological features underlying the course of diagnostic-to-MRD MM. To summarize, the MRD stage of disease represents a critical step in MM pathogenesis and progression. Demonstration of MM MRD biology should help us to deal with the curative difficulties.
