High world sugar prices: is Asia’s production cycle to blame?
Authors: Todd Martin
Published: December 2019

The current high world sugar prices reflect a major imbalance between global supply and demand, which has reduced stocks to very low levels. Although it remains to be seen whether prices will rise much above current values, it is clear that the supply chain will remain stretched throughout 2010 and this will help to maintain prices at a high level.

Published: December 2019

The aim of this work was to study the possibility of valorization of the carbonatation lime from the sugarbeet industry by production of compost using in the same time the excess of bagasse from the cane sugar industry together with household waste (organic materials). Three experiments were conducted: in the first experiment the carbonatation lime (dry substance content 83.7%) at a content of 32% was composted with bagasse (DS 89.3%) and household waste (DS 13.4%), while in the second experiment the compost did not contain the carbonatation lime (only bagasse and household waste in the same proportions). In the third experiment the concentration of carbonatation lime in the mixture (carbonatation lime – bagasse – household waste) was increased to 50%. After 75 days of composting with natural aeration, a good evolution of the temperature for all the composts was observed. In the final step of composting, all composts have pH values of 8.0–8.5 and the ratio of carbon/nitrogen was reduced to the recommended value. The compost with carbonatation lime could be used as fertilizer for the Moroccan soils.

BALLOON TRAWL; A SAFE AND EFFECTVE WAY OF REMOVING COMMON BILE DUCT (CBD) EMBEDDED STENTS
Authors: Mehmood Shafqat , Zeb Faisal
Published: December 2019

Biliary stenting has been used since the 1970s to relieve biliary obstruction for a variety of causes including benign and malignant biliary strictures. Migration of stents proximally into the biliary tree or distally into the intestinal tract is relatively uncommon. We report a case of a 64-year-old female with a peri-ampullary tumour, who had symptomatic obstructive jaundice following endoscopic retrograde cholangiopancreatography and plastic stent insertion. Follow-up imaging showed proximal migration of the plastic stent and blockage of the distal common bile duct (CBD) secondary to the periampullary tumour. The biliary stent was safely removed endoscopically using balloon trawl. This case highlights that, while biliary stenting for strictures is generally safe and effective, stent migration to proximal CBD can occur. Balloon trawl is safe and effective way of removing such stents. Key words: Biliary stricture, common bile duct, endoscopic retrograde cholangiopancreatography, periampullary tumour, stents

NEOADJUVANT WEEKLY NAB-PACLITAXEL PLUS CARBOPLATIN FOLLOWED BY DOXORUBICIN PLUS CYCLOPHOSPHAMIDE WITH BEVACIZUMAB ADDED CONCURRENTLY TO CHEMOTHERAPY FOR OPERABLE TRIPLE-NEGATIVE INVASIVE BREAST CANCER
Authors: Sachdev Jasgit C. , Snider Jessica N. , Allen Jeffrey W. , Schwartzberg Lee S. , Young Robyn R. , Javed Ahmed Y. , Smeltzer Matthew P. , Yunus Furhan , Verrier Carmel S. , Jahanzeb Mohammad
Published: December 2019

Purpose: This phase II neoadjuvant study investigated whether nab paclitaxel, carboplatin and bevacizumab given before neoadjuvant doxorubicin/cyclophosphamide (AC) produced higher pathologic complete response (pCR) rates in triple- negative breast cancer (TNBC) compared with historical results achieved with standard anthracycline/taxane regimens. Patients and Methods: Eligible patients with operable TNBC ≥2 cm received four cycles of carboplatin (area under the curve 6, day 1) plus nab-paclitaxel (100 mg/m2, days 1, 8 and 15) every 28 days, followed by four 14-day cycles of AC neoadjuvantly, with bevacizumab 10 mg/kg every 14 days for the rst 6 cycles of neoadjuvant chemotherapy, resuming postoperatively to complete 1 year of antibody treatment. In breast pCR and pCR (breast + nodes) were primary and secondary endpoints, respectively. Results: Due to slow accrual, the study was closed after enrollment of 42 of 60 planned patients. Of the 38 patients who underwent surgery (ef cacy population), 22 (58%) achieved an in-breast pCR and 19 (50%) achieved a pCR (breast + nodes). Neutropenia was the most common Grade 3/4 adverse event (57% Grade 3 and 31% Grade 4), but only 1 patient required hospitalisation and IV antibiotics for neutropenic fever. Other Grade 3/4 events included anaemia (24%), thrombocytopenia (29%) and peripheral neuropathy (Grade 3, 5%). Conclusion: Our results demonstrate a substantially higher pCR rate, both in-breast and breast + nodes, with the combination of nab paclitaxel plus carboplatin followed by AC, with concurrent bevacizumab, versus historic pCR rates with anthracycline-taxane regimens alone, supporting further investigation of this regimen, preferably in molecularly driven subsets, for the neoadjuvant treatment of patients with TNBC. Key words: Bevacizumab, breast cancer, carboplatin, nab-paclitaxel, neoadjuvant, triple-negative

AN UNUSUALLY PROLONGED SURVIVAL IN METASTATIC PERIAMPULLARY PANCREATIC ADENOCARCINOMA
Authors: Maqsood Shafaq , Ahmad Usman
Published: December 2019

Periampullary cancer is the term used for neoplasms arising from the head of pancreas, ampulla of Vater, distal bile duct and periampullary region of duodenum. Of these, the pancreatic adenocarcinoma carries the worst prognosis with majority of mortalities within the 1st year. The overall 5-year survival is <3%. Studies have shown that pancreatic carcinoma has the shortest median survival of 17.1 months of all periampullary carcinomas. With the development of metastasis, the median survival tends to reduce to 3–6 months. We are reporting a case of metastatic periampullary pancreatic adenocarcinoma that received minimal and interrupted chemotherapy due to poor tolerance and yet managed to survive far beyond the reported median survival. Key words: Adenocarcinoma, pancreas, periampullary, prognosis

Published: December 2019

Purpose: Laryngeal cancers are amongst the most common cancers affecting head and neck region. In this study, we analyse the overall survival (OS) following hypofractionated radiotherapy (RT) in early stage glottic carcinoma treated at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore. Methods: Between October 2003 and June 2009, 87 patients with early stage glottic carcinoma were treated with hypofractionated RT. All patients were included in the study. The ratio of male: female is 94%:6%. Mean age was 62 years (range 31–83 years). 66% of the patients were smokers. AJCC stage was T1a in 76%, T1b 20% and T2 in 4% of the patients. Histological distribution was; squamous cell carcinoma 97%, verrucous carcinoma 2% and squamous cell spindle variant 1%. Median follow-up time was 59 months (range 4–122 months). RT dose was 55 Gy in 20 fractions over a period of 4 weeks. Median RT treatment time was 28 days (range 23–35 days). Patients that lost to follow-up were contacted through telephone. Results: The 10-year OS was 83%. Patterns of failure was 7 local and 1 distant while 1 patient had persistent disease. 15 patients were dead at the time of study. Cause of death; 13 patients died due to Ischemic heart disease and 2 due to primary disease. Conclusion: Hypofractionated RT 55 Gy in 20 fractions seems to achieve good OS while offering potential for optimizing resources usage. Key words: Glottic carcinoma, hypofractionated, overall survival, radiotherapy

Published: December 2019

It is critical to identify the cell of origin of cancer and the genes/proteins/transcriptional/epigenetic factors of that cell. Here, we review studies on head and neck cancer stem cells (CSC) in the hope of developing better understanding of their role highlighting their importance as novel drug targets. CSC model has introduced a hierarchical conceptual framework for the interpretation of intratumour heterogeneity within tumour. This, in turn, has culminated in a major paradigm shift in terms of how different types of cancers can be targeted for treatment. Several malignancies conform to the CSC model of tumour growth yet identification of CSC markers remains a profound challenge.Key words: Chemo- and radio-resistance, head and neck cancer stem cells, proteomics, treatment modalities

Published: December 2019

Multiple myeloma (MM) is a plasma cell disorder primarily involving bone marrow. Extramedullary involvement is less common, with central nervous system (CNS) myelomatosis being a rare entity and such presentation carries extremely dismal prognosis. We present case of a 40 years old male with MM who was initially treated with 6 cycles of Cyclophosphamide, Thalidomide and Dexamethasone resulting in complete response. 2 years later he presented with CNS myelomatosis and scrotal involvement and was initially treated with Bortezomib and dexamethasone, cranial irradiation and intrathecal Methorexate, Cytarabine, Hydrocortisone (TRIO IT), along with radical orchiectomy and testicular radiation during the course of treatment. However, after initial response his disease showed clinical and radiological progression after 4 months of therapy. He was switched to high dose Methotrexate (HD-MTX) with TRIOITand later Lenalidamide and dexamethasone (Len/dex) was added to the above regimen. He continued to show good clinical response but his cytology remained persistently positive, therefore, HD-MTX was discontinued in the later course of treatment. Subsequently he was started on best supportive care only, when his neurological status deteriorated further. He survived almost 9 months after a diagnosis of CNS myelomatosis. Patients with multiple myeloma, presenting with neurological symptoms should always be investigated for the possibility of CNS MM. CNS relapse is a fatal disease with poor prognosis. Recommended treatment must include a systemic anti-MM regimen that crosses the BBB (ideally Immunomodulatory drugs (IMiDs) IMiDs-dexamethasone based therapy), CNS irradiation and intrathecal chemotherapy.Key words: Multiple myeloma, central nervous system myelomatosis, therapy

Published: December 2019

Solitary fibrous tumours (SFTs) are fibroblastic mesenchymal tumour primarily identified in the pleura but are now being reported in other anatomic sites as well. SFT is generally characterised as a radiologically confined neoplasm composed of a proliferated spindle cells arranged in patternless manner. Intervening tissue shows prominent haemangiopericytoma-like vessels. Stroma is usually fibrous. Tumour is positive for CD34. SFT has a specific translocation representing fusion NAB2 with STAT6 genes. This translocation can be highlighted with very good specificity and sensitivity using STAT6 immunohistochemical stain. Some cases of SFTs have also been described in the breast. Rarely, SFT can show aggressive behaviour. SFT enters the differential diagnoses of benign and malignant spindle cell tumours of breast and it is, therefore, important that its clinical, radiological and pathological features are known to clinicians and diagnosticians.

The Effect of Land Fraction and Host Star Spectral Energy Distribution on the Planetary Albedo of Terrestrial Worlds
Authors: Rushby Andrew J. , Shields Aomawa L. , Joshi Manoj
Published: December 2019

The energy balance and climate of planets can be affected by the reflective properties of their land, ocean, and frozen surfaces. Here we investigate the effect of host star spectral energy distribution (SED) on the albedo of these surfaces using a one-dimensional energy balance model. Incorporating spectra of M-, K-, G-, and F-dwarf stars, we determined the effect of varying fractional and latitudinal distribution of land and ocean surfaces as a function of host star SED on the overall planetary albedo, climate, and ice-albedo feedback response. While noting that the spatial distribution of land masses on a given planet will have an effect on the overall planetary energy balance, we find that terrestrial planets with higher average land/ocean fractions are relatively cooler and have higher albedo regardless of star type. For Earth-like planets orbiting M-dwarf stars, the increased absorption of water ice in the near-infrared, where M-dwarf stars emit much of their energy, resulted in warmer global mean surface temperatures, ice lines at higher latitudes, and increased climate stability as the ice-albedo feedback became negative at high land fractions. Conversely, planets covered largely by ocean, and especially those orbiting bright stars, had a considerably different energy balance due to the contrast between the reflective land and the absorptive ocean surface, which in turn resulted in warmer average surface temperatures than land-covered planets and a stronger potential ice-albedo feedback. While dependent on the properties of individual planetary systems, our results place some constraints on a range of climate states of terrestrial exoplanets based on albedo and incident flux.
A Robust and Efficient Deep Learning Method for Dynamical Mass Measurements of Galaxy Clusters
Authors: Ho Matthew , Rau Markus Michael , Ntampaka Michelle , Farahi Arya , Trac Hy , Póczos Barnabás
Published: December 2019

We demonstrate the ability of convolutional neural networks (CNNs) to mitigate systematics in the virial scaling relation and produce dynamical mass estimates of galaxy clusters with remarkably low bias and scatter. We present two models, CNN1D and CNN2D, which leverage this deep learning tool to infer cluster masses from distributions of member galaxy dynamics. Our first model, CNN1D, infers cluster mass directly from the distribution of member galaxy line-of-sight velocities. Our second model, CNN2D, extends the input space of CNN1D to learn on the joint distribution of galaxy line-of-sight velocities and projected radial distances. We train each model as a regression over cluster mass using a labeled catalog of realistic mock cluster observations generated from the MultiDark simulation and UniverseMachine catalog. We then evaluate the performance of each model on an independent set of mock observations selected from the same simulated catalog. The CNN models produce cluster mass predictions with lognormal residuals of scatter as low as 0.132 dex, greater than a factor of 2 improvement over the classical M–σ power-law estimator. Furthermore, the CNN model reduces prediction scatter relative to similar machine-learning approaches by up to 17% while executing in drastically shorter training and evaluation times (by a factor of 30) and producing considerably more robust mass predictions (improving prediction stability under variations in galaxy sampling rate by 30%).

Redang Islands Marine Park consists of nine islands in the state of Terengganu, Malaysia. Redang Island is one of the largest off the east coast of Peninsular Malaysia, which is famous for its crystal-clear waters and white sandy beaches. The ichthyofauna of the Redang archipelago was surveyed by underwater visual observations between August 2016 and May 2018. Census data were compiled with existing records into the checklist of the marine fish of the Redang archipelago presented herein. A total of 314 species belonging to 51 families were recorded. The most speciose families (Pomacentridae, Labridae, Scaridae, Serranidae, Apogonidae, Carangidae, Gobiidae, Chaetodontidae, Lutjanidae, Nemipteridae and Siganidae) were also amongst the most speciose at the neighbouring Tioman archipelago (except Chaetodontidae). The coral fish diversity index value for the six families of coral reef fishes (Chaetodontidae, Pomacanthidae, Pomacentridae, Labridae, Scaridae and Acanthuridae) of the study sites was 132. We estimated that there were 427 coral reef fish species in the Redang archipelago. According to the IUCN Red List, eight species are Near Threatened (Carcharhinus melanopterus, Chaetodon trifascialis, Choerodon schoenleinii, Epinephelus fuscoguttatus, E. polyphekadion, Plectropomus leopardus, Taeniura lymma and Triaenodon obesus), eleven are Vulnerable (Bolbometopon muricatum, Chaetodon trifasciatus, Chlorurus sordidus, Dascyllus trimaculatus, Epinephelus fuscoguttatus, E. polyphekadion, Halichoeres marginatus, Heniochus acuminatus, Nebrius ferrugineus, Neopomacentrus cyanomos and Plectropomus areolatus) and three are Endangered (Amphiprion clarkia, Cheilinus undulatus and Scarus ghobban) in the Redang archipelago.

Five species are new records for Malaysia (Ctenogobiops mitodes, Epibulus brevis, Halichoeres erdmanni, H. richmondi and Scarus caudofasciatus) and 25 species are newly recorded in the Redang archipelago.
Siberian weasel Mustela sibirica Pallas, 1773 predatism on bats during winter period
Authors: Zhigalin Alexander
Published: December 2019

This work presents the results of a three-year natural environment experiment in a cave in Barsukovskaya, Siberia), aimed at assessing the possible impact of mammals preying on a wintering group of bats. The average consumed biomass amount per year was about 2108 g and the estimated number of prey animals was 214, which is about 20% of the maximum number of animals observed. The biomass consumed poorly correlates with the number of animals in the cave. The proportion of the various species remaining in the excrement of predators is strongly determined by the number of these species in the accessible part of the cave. The amount of excrement indicates the regular predatism on bats and, therefore, the presence of specific behavioural adaptation in Mustela sibirica.

The Hydradephaga (Coleoptera, Haliplidae, Gyrinidae, and Dytiscidae) fauna of Cape Breton Island, Nova Scotia, Canada: new records, distributions, and faunal composition
Authors: Alarie Yves
Published: December 2019

The Haliplidae, Gyrinidae, and Dytiscidae (Coleoptera) of Cape Breton Island, Nova Scotia, Canada were surveyed during the years 2006–2007. A total of 2027 individuals from 85 species was collected from 94 different localities, which brings to 87 the number of species recorded for this locality. Among these,Heterosternuta allegheniana(Matta & Wolfe),H. wickhami(Zaitzev),Hydroporus appalachiusSherman,H. gosseiLarson & Roughley,H. nigellusMannerheim,H. puberulusLeConte,Ilybius picipes(Kirby), andI. wasastjernae(C.R. Sahlberg) are reported for the first time in Nova Scotia. The Nearctic component of the fauna is made up of 71 species (81.6%), the Holarctic component of 16 species (18.4%). Most species are characteristic of both the Boreal and Atlantic Maritime Ecozones and have a transcontinental distribution but 19 species (21.8%), which are generally recognized as species with eastern affinities. In an examination of the Hydradephaga of insular portions of Atlantic Canada, it was shown that the island faunas of Cape Breton Island and Prince Edward Island are very similar (87 and 84 species, respectively) despite differences in composition suggesting that more Hydradephaga species have yet to be found on Cape Breton Island.

ECHO: A Pilot Health Literacy Intervention to Improve Hypertension Self-Care
Authors: Warren-Findlow Jan , Coffman Maren J. , Thomas Erin Vinoski , Krinner Lisa M.
Published: December 2019

Background:

Medication adherence and diet and weight control are essential contributors to blood pressure management. Low health literacy is also associated with poor health behaviors and outcomes among adults with hypertension.

Objective:

This study aims to pilot test the acceptability and feasibility of a brief health literacy intervention focused on hypertension self-care and to assess changes in self-care activities.

Methods:

We recruited patients with hypertension who were treated at a low-cost clinic. A 2-hour evidence-based class was delivered in Spanish and English, and a telephone follow-up survey was conducted 1 month later. Intervention content included health literacy activities, nutrition education, and medication use. Participants engaged in reading, writing, a group activity, and critical discussion. Health literacy was measured using the Newest Vital Sign and the Test of Functional Health Literacy in Adults.

Key Results:

The intervention was delivered to 52 English- (52%) and Spanish-speaking adults (48%) with a mean age of 52.3 years (
SD
7.9). More than one-half had Stage 1 or 2 hypertension (54%), and 56% had inadequate health literacy. At 1-month follow-up, participants showed improvement on all self-care measures with significant mean differences (
p
< .05) on diet adherence and weight management activities. These improvements were largely among Hispanics and those with low health literacy.

Conclusions:

Results suggest that teaching targeted self-care skills in a brief health literacy intervention can be effective in improving self-care activities relating to diet and weight management among vulnerable populations.

HLRP: Health Literacy Research and Practice
. 2019;3(4):e259–e267.]

Plain Language Summary:

This study explored the effects of a 2-hour health education class on self-care behaviors. At the follow-up, participants reported better self-care behaviors. Effects were more pronounced among those with low health literacy, suggesting brief exposure to health education may improve high blood pressure in this population.
Using Relative Tie Strength to Identify Core Teams of Scientific Research
Authors: Zhang Meishu , Jia Yu , Wang Nianxin , Ge Shilun
Published: December 2019

In China, it has long become imperative for the management of education and science and technology to build high-level scientific and technological innovation teams. Scientifically and accurately identifying core scientific research teams is an important condition for cultivating and building such teams. The absolute threshold method (e.g., c-level clique at, n- clique, k-core) is the prevailing means of identifying core teams and their core members. In fact, effects such as “the preference-dependent effect”, “the apostle effect” and “the star effect”, the cooperative relationship between the researchers is not even. This study, based on the co-authorship network, found that not choosing the absolute threshold properly can easily lead to poor identification of core members of some teams. Even worse, when the absolute threshold is too large, this “uniform” evaluation criterion of tie strength results in the elimination of some core teams in some disciplines. This paper uses relative tie strength to identify core scientific research teams from a new perspective, which can effectively avoid the situation of some core team members being ignored because of the mandatory requirements of the absolute tie strength among members, and can also solve the challenge of threshold selections for identifying different teams.

Mapping and Modeling the Distribution, Abundance, and Habitat Associations of the Endangered Fat Threeridge in the Apalachicola River System
Authors: Kaeser Adam J. , Smit Reuben , Gangloff Michael
Published: December 2019

Large, Coastal Plain rivers of the southeastern United States contain some of the most diverse freshwater communities in North America; however, surveying the fauna of these large rivers presents numerous logistical and statistical challenges. We assessed the contemporary distribution, abundance, and habitat associations of the endangered fat threeridge mussel Amblema neislerii throughout the Apalachicola River system in northwestern Florida. To achieve this goal, we used side scan sonar to map the distribution of mesohabitats and conducted a system-wide, quantitative survey to define mussel habitat associations. We then used habitat and mussel data to develop predictive models of spatial distribution and to estimate the abundance of fat threeridge across the entire Apalachicola River system. Findings revealed a broadly distributed (i.e., 128 river kilometers occupied), robust population of approximately 9 million individuals (95% CI = 5–12 million), with a center of distribution (i.e., where abundance and occurrence were highest) approximately 45–80 river kilometers upstream of the river mouth. Fat threeridge primarily occupy fine sediment mesohabitats characterized by smooth/plane bedforms that are clearly definable via sonar habitat mapping. We hypothesize that this species may be particularly sensitive to the availability of stable, fine sediments during one or more critical life history phases and that the availability of this habitat may explain its restricted distribution in tributary rivers. Our study provides a quantitative, replicable foundation upon which future population and habitat monitoring can be based.

Published: December 2019

Habitat restoration and enhancement objectives for wintering waterfowl are typically derived by a bioenergetics modeling approach. This approach has been developed as a planning tool to identify the amount of foraging habitat required to meet North American Waterfowl Management Plan population objectives. Our objective was to provide the energetic supply component of the bioenergetics model at an important wintering area for American black ducks Anas rubripes in the Atlantic Flyway, the Eastern Shore of Virginia. We estimated food availability among four main wetland cover types used by overwintering American black ducks: brackish water, freshwater, mudflat, and salt marsh. Mudflat (221 ± 50 kg/ha) and salt marsh (728 ± 175 kg/ha) had the highest amounts of available invertebrate food density, and freshwater (42 ± 9 kg/ha) had the highest amounts of available seed biomass. Our results suggest that seed density found in freshwater wetlands on the Eastern Shore of Virginia is considerably lower than densities found in inland freshwater cover types used by dabbling ducks. We also found that levels of invertebrate density found in Virginia mudflat and salt marsh are considerably lower than levels on Long Island, New York, and in southern New Jersey. Lower levels of food density compared with both more inland and northern wintering areas suggest that American black ducks wintering in Virginia are more likely to be limited by forage availability than American black ducks and other dabbling ducks wintering both inland and in the northern portion of the wintering range.
Increased Probability and Efficiency of Gar Capture Using Multi- vs. Monofilament Gill Nets
Authors: Richardson Bradley M. , Flinn Michael B.
Published: December 2019

Monofilament gill nets have increased in popularity in recent decades and are often considered to be superior to multifilament gill nets; however, this claim is still contested by many researchers. Target species, habitat characteristics, and mesh characteristics can all affect the efficacy and selectivity of these nets. Increased angling interest and declining home ranges have led to increased management efforts for gars (Lepisosteidae) among state and federal agencies. However, the sampling of gar species is notoriously difficult and has hindered subsequent management actions in some cases. This study aimed to compare probability and incidence rate of gar capture between net constructions (multi- vs. monofilament), net length (75 vs. 46 m length), sampling habitat (run vs. bend), and deployment orientation (parallel vs. perpendicular vs. diagonal in relation to river channel). We also assessed mode of capture investigate the effects of small mesh sizes (50.8 mm) on capture and potential retention of gars captured in gill nets. Results showed that the use of multifilament gill nets were three times more likely to capture at least one gar (1.3–6.3, 95% CI) than monofilament nets. Multifilament gill nets also averaged approximately twice as many gars per net than monofilament gill nets. Increasing water temperature also significantly increased the probability of gar capture, particularly above 15°C. In addition to mesh type and water temperature, habitat and gill net orientation also had significant effects on the incidence rate of gar capture. We primarily captured gars captured in the gill nets by entanglement (63%), which may have allowed for the wide range of length frequencies sampled in this study. Our study highlights the importance of considering multiple gill net constructions, deployments, and habitats when designing a research project or management plan for gar species. The use of multifilament gill nets can help resource managers to sample gar populations more effectively, resulting in better management strategies and practices.

Aberrant patches of white skin or fur known as hypopigmented marks have been observed in many mammal species worldwide, but they are typically limited to only a few individuals in a population. Hypopigmented marks were documented in only two museum specimens of the federally endangered Florida bonneted bat (Eumops floridanus) as early as 1950, but recent observations suggest that these marks may be more common in this species than previously believed. To better understand the occurrence and persistence of hypopigmented marks in Florida bonneted bats, we evaluated the variation in frequency, compared effects on survival, and assessed spatial and temporal differences of specimens at an intensively studied site and across the species range. From 2014 through 2017, we regularly captured Florida bonneted bats for demographic studies at Babcock–Webb Wildlife Management Area in Charlotte County and we observed hypopigmented marks on 172 (80.8%) of 213 individuals, the highest incidence known for bats. The proportion of hypopigmented marks did not differ with sex, age at first capture, or reproductive status, and importantly, we documented the persistence of hypopigmented marks in individuals over multiple months. We also found no difference in survival or capture probability between hypopigmented and solid-colored individuals. Using data from concurrent mist-net studies, we assessed the proportion of Florida bonneted bats with hypopigmented marks across the species range and found a higher proportion of individuals with hypopigmented marks in the two northern counties (80.8% in Charlotte County and 61.5% in Polk County) compared with the two southern counties (21.1% in Miami–Dade County and 16.7% in Collier County). Additionally, we compared the proportion of hypopigmented individuals in Miami–Dade County between recently captured/collected bats (post-2004) and historically (pre-1965) collected museum specimens and found more hypopigmented marks in recently captured bats. The persistence of hypopigmented marks over time, the presence of marks on bats from different locations, and our finding of no effect of age on the presence of marks all strongly suggest that the hypopigmented marks in Florida bonneted bats are the result of genetic rather than environmental factors. Further study is required to understand the mechanism underlying the high incidence of hypopigmented marks and to determine whether the prevalence of hypopigmented marks indicates low genetic diversity that could threaten Florida bonneted bats.
Les généalogies polynésiennes, une mise en récit du monde sociocosmique, de son origine et de son ordre
Authors: Chave-Dartoen Sophie , Saura Bruno
Published: December 2019

Une des caractéristiques des traditions orales polynésiennes tient à l’importance qu’y occupent les récitations généalogiques, dont certaines s’étendent sur plus de cent générations. Celles de chefs ou de groupes sociaux éminents sont souvent enchâssées dans des cosmologies mettant en scène des forces naturelles présentées comme des ancêtres. Inversement, c’est souvent sous une forme généalogique que se déclinent les anciennes cosmogonies polynésiennes. L’étude de ces divers récits généalogiques polynésiens, menée principalement ici sur la base d’exemples des îles Tonga, Marquises et Hawai’i, permet de dégager certaines caractéristiques importantes de ces sociétés. Ces textes, généralement sacrés et poétiques, sont des constructions sociales et historiques qui renforcent l’ordre sociocosmique et, dans de nombreux cas, légitiment la position des groupes sociaux en mesure de faire valoir une prééminence.
« Et maintenant, nous allons marcher dans les pas du chemin qui vient de Tamoa… » Un cas d’usage du récit généalogique à Tabiteuea, Kiribati
Authors: Camus Guigone
Published: December 2019

Les atolls de Kiribati, dans le Pacifique central, ont produit des récits des plus saisissants. Prenant parfois l’aspect de petits livres, nombre d’entre eux, conservés dans des archives d’ethnologues, de missionnaires ou d’administrateurs coloniaux, relatent la naissance et l’organisation du cosmos, l’histoire des migrations des ancêtres des habitants des atolls, ainsi que les modalités de l’organisation territoriale et sociale de ces ancêtres. Offrant une place conséquente à l’énumération onomastique et toponymique, ils constituent des supports de la mémoire orale et peuvent être utilisés par des individus qui, confrontés à un litige foncier ou statutaire, s’y référeront pour rappeler que leur filiation, étreinte dans un maillage généalogique attestant de droits fonciers multilocaux hérités en double ligne, leur permet de jouir de ces droits en toute légitimité. Nous suivons ici la plume d’un auteur, Kambati Roteman, originaire de l’atoll de Tabiteuea. En 1948, il confie à Katharine Luomala, ethnologue du Bishop Museum qui y effectue un terrain de quelques mois, un cahier d’écolier sur les pages duquel il se raconte, au travers d’un long récit dont la structure généalogique apparaît de manière plus ou moins ostensible. Tout au long de son récit, l’auteur joue sur la quantité et le rythme et, alternant entre prose longue et détaillée et listes généalogiques, instaurant une discontinuité littéraire, il recourt habilement à des variations narratives qui placent ses ancêtres à des niveaux hiérarchiques qui lui permettent de situer son identité dans des dimensions philosophiques et temporelles variables.
Implications of Mixing Methods
Authors: Cosgrove Preston B.
Published: December 2019

Much like a jigsaw puzzle box top guides one in how to connect the pieces, a research paradigm operates as a conscious or subconscious influence in conducting a research project. The promise—and challenge—of mixed methods research is that it involves the use of two box tops, and this chapter discusses the subsequent implications on the researcher. The first effect is through the need to balance the paradigmatic distinctives, requiring the researcher to identify one of four broad ways to address the paradigm divide at the heart of qualitative and quantitative research. The second effect is through the need to balance the validation distinctives. Making research credible is an essential component of any study, and the issues magnify given the stark differences between qualitative and quantitative validity orientations. Both implications reveal the level of sophistication required for the researcher when conducting a mixed methods project.
Analyzing Qualitative Data
Authors: Jones Janice E.
Published: December 2019

This chapter provides an introduction to the process of qualitative analysis and uses step-by-step examples to provide an idea of how the process of qualitative analysis actually works. This chapter is intended to give the researcher a place to begin and to inspire a deeper dive into this rewarding form of data analysis. While qualitative data analysis can be time consuming, the rewards that come from immersion in the data far outweigh the time spent doing so.
To Whose Benefit? At What Cost?
Authors: Baker Aaliyah A.
Published: December 2019

This chapter takes a conceptual approach to addressing issues of ethics in research with human participants. The author proposes preliminary questions at the onset of a research study that deal with the issue of addressing researcher responsibility. The chapter argues ethical considerations surround epistemology and impact when conducting mixed methods research. Moreover, defining the interaction between researchers and participants is crucial. The author challenges early career practitioners to ask the question ‘To whose benefit is the research?' but more importantly ‘At what cost when conducting research?' Recommendations for engaging in an applied social science methodology include understanding critical epistemological and philosophical perspectives and grappling with the potential impact and outcomes of research. This level of critical awareness enables research to display complex processes that address social, political, and moral ideals that resonate with and value human experience as knowledge.
Social Loafing

Published: December 2019

The performance of an employee is quite important for the organizations encountering a severe competition in today's conditions. For the tourism establishments, in which the number of the employees is quite high, providing innovative and quality service, meeting the customer satisfaction, is directly related to the performance of the employee. However, a part of the employees cannot display the expected performance. In literature, this situation is explained as social loafing. In literature, social loafing is the tendency of individuals to expend less effort when working in groups than when working alone. This undesirable situation for the tourism establishments decreases productivity and performance of the business. In the study, firstly the concept of social loafing, the approaches explaining social loafing, the first researches in the literature, and social loafing in the workplace are summarized. Then, the social loafing phenomenon in tourism industry, the studies carried out regarding this subject, and the preventive suggestions for social loafing are given place.
