Authors: Alegret Laia , Kaminski Michael A.
Published: May 2022

The International Workshops on Agglutinated Foraminifera (IWAF) are part of a long-term effort to understand the taxonomy, classification, ecology, and biostratigraphy of this ancient and diverse group of microfossils. Since 1981, the IWAF meetings have been held approximately every four years in a different European country, and have produced a remarkable body of scientific literature. The 9th IWAF in Zaragoza, Spain hosted 53 scientists who gave a total of 56 contributions. The current Micropaleontology issue contains the scientific results of eight presentations given at the IWAF-9.
A new methodological approach to evaluate the mass and volume distributions of grains in an agglutinated foraminiferal test
Authors: du Chatelet Eric Armynot , Frontalini Fabrizio , Guillot Francois
Published: May 2022

Chemical maps and images were made of the test of Textularia earlandi, an agglutinated foraminifera, by ESEM-EDS (Environmental Scanning Electron Microscopy-Energy Dispersive Spectrometer). The specimen is about 300μm long, comprising 17 imbricated growth chambers. In order to evaluate themass distribution along the test, mineral grain densities, as deduced through chemical mapping, as well as the volumes of 650 grains, were treated by geostatistical methods. The volume of the imbricated spheres was 3D-modelled using theMonte-Carlo method. It is calculated that the volume of the chamber grows regularly. The mass of the chambers undergo some variation due to occurrence of various proportions of minerals with different densities. The mass distribution within each chamber is smoothly distributed. Further development on other protists with various shape and geometry could be easily imagined.
A standard SEM-EDS methodology to determine the test microstructure of fossil agglutinated foraminifera
Authors: Mancin Nicoletta , Basso Elena , Kaminski Michael A. , Dogan A. Umran
Published: May 2022

We propose a methodology as a possible standard approach for micropaleontological studies addressed to detect test microstructure and the chemical/mineralogical composition of grains used by agglutinated foraminifera. Themethodology was tested on over 200 specimens of fossil agglutinated foraminifera, mostly belonging to the textulariid group, collected from Cenozoic successions of theMediterranean region. The approach assesses the internal morphological and compositional features of agglutinated foraminifera by Scanning ElectronMicroscopy (SEM) and Energy Dispersive Spectroscopy (EDS) analyses, performed on representative specimens that were embedded in epoxy resin and subsequently sectioned and polished.With respect to similar techniques that perform SEM and EDS analyses mostly on the agglutinated wall surface of free specimens or broken tests, this methodology provides the preparation of cross sections of isolated individuals. The use of cross sections has the advantages of: (i) documenting the internal chamber arrangement and other morphological elements (such as alcoves or canaliculi), even considering if the recognized features remain constant or change during ontogeny; (ii) measuring the testwall thickness and the grain distributionwithin the testwalls; (iii) detecting the chemical composition of the agglutinated grains and the cement in order to highlight mineralogical grain selectivity and arrangement; (iv) studying the agglutinated grains in their original position within the test wall and during test growth; and (v) the elemental compositional data collected from polished sections are more accurate than those collected on the rough surface of specimens.
The Eocene-Oligocene turnover of Deep-Water Agglutinated Foraminifera at ODPSite 647, Southern Labrador Sea (North Atlantic)
Authors: Kaminski Michael A. , Ortiz Silvia
Published: May 2022

We present a new record of deep-water agglutinated foraminifera (DWAF) across the Eocene-Oligocene Transition (EOT) in the southern Labrador Sea (ODP Site 647). We studied 82 samples from Cores 647A-37R to -27R, and recovered over 100 species and generic groups. The EOT represents an interval of rapid climatic change connected with global cooling, Antarctic glaciation, a substantial decrease in atmospheric CO2, and concurrent changes in the composition of deep waters in the world ocean. Our high-resolution quantitative study of the DWAF faunal succession in abyssal Hole 647A confirms earlier findings that the EOT was an interval of significant faunal turnover. The faunal succession in Hole 647A is subdivided into two assemblages based on the stratigraphic ranges of characteristic benthic foraminiferal species: late Eocene Spiroplectammina trinitatensis-Reticulophragmium amplectens Zone and early Oligocene Ammodiscus latus-Turrilina alsatica Zone. The boundary between these zones, i.e., the Eocene/Oligocene (E/O) boundary, is characterized by the disappearance of 11 DWAF taxa, most of them organically-cemented taxa. The boundary interval was also characterized by a striking sharp decrease in DWAF abundance and diversity. Organically-cemented DWAF taxa increased in abundance in the early Oligocene, but their diversity and abundance never recovered to Eocene values. These data suggest a deepening of the calcite compensation depth and associated changes, such as more vigorous ocean circulation in coincidence with the E/O boundary interval. The analysis of DWAF morphogroups reveals an acme in robust suspension-feeding tubular forms previous to the extinction, suggesting increased bottom water activity. The E/O boundary interval is characterized by an increase in DWAF infaunal taxa and Spiroplectammina species, probably related to increased productivity, as already suggested by the analysis of benthic elongate-cylindrical foraminifera at the same locality. The faunal turnover across the EOT at Hole 647A suggests more vigorous deep-ocean circulation in the latest Eocene and across the E/O boundary interval in the Labrador Sea. It seems reasonable to link the disappearance of DWAF at the E/O boundary at Site 647 to more than one mechanism, including inferred higher productivity, possible competition from calcareous benthic foraminifera, changes in the CO2 content of the atmosphere and ocean, the deepening of the calcite compensation depth, and concurrent changes in taphonomic conditions caused by changes in the water masses in the North Atlantic.
Transitional forms in the Eprolithus-Lithastrinus lineage: a taxonomic revision of Turonian through Santonian species
Authors: Corbett Matthew J. , Watkins David K.
Published: May 2022

The evolution of Lithastrinus from Eprolithus is observed in Turonian through Santonian material via variation in the number and morphology of wall elements. Previously, the shape of projections off the wall elements (rays) the size of the diaphragm, and inclination and twisting about the central area of the wall elements have been used to separate the genera, but these criteria are too general to consistently separate transitional 7-rayed forms. The more reliable criteria we have defined for distinguishing two different taxa, Eprolithus moratus and Lithastrinus septenarius, provides a more accurate biostratigraphic placement for these intermediate forms. The younger late Turonian to middle Santonian form, L. septenarius, is separated from the older form, E. moratus, through reduced central depression size (<50% the width of the entire central area) and rays that are generally longer (>50% the width of the central area) and angled away from the ring of elements (>15°). In Lithastrinus the rays only project from the proximal and distal sides of the wall elements, while in E. moratus they extend as a single ridge between the two sides. When in the focal plane of the diaphragm the wall elements appear as a rounded collar in L. septenarius, which can also be used to differentiate between the two taxa, especially in poorly preserved material.

Published: May 2022

Benthic foraminifera are single-celled organisms abundantly found in all kind of marine environments from brackish estuaries to the deep ocean basins at all latitudes. Foraminifera are covered with an organic test which accumulate in the sediment and make up a significant amount of sedimentary rock. Many species have well defined salinity and temperature preferences making them particularly useful for reconstructing ecological changes occured in the past. The fossil tests not only used for paleoenvironmental interpretition, but also for biostratigraphy and age-dating. Anthropogenic pollution or environmental factors may cuase abnormal development of the test, such as aberrant chamber shape and size, twisted or distorted chamber arrangement, multiple apertures, twin, triplet and even quadruplet forms. These abnormalities are commonly used as indicators of pollution. Many researchers have studied the recent benthic and planktic foraminifera of the Mediterranean fauna. The studies have investigated the distribution and abundance of the species, composition of the foraminiferal assemblages, ecological factors and interractions of tests with the substrate. Recent studies, mainly focused on the alien species and their ecological impact. Despite the numerous researches, there is a lack of a comprehensive illustrated guide to the Mediterranean foraminifeal fauna, except the “Mediterranean Foraminifera” (Cimerman and Langer 1991), which included samples from Adriatic and Tyrrhenian Seas, representing mostly the western Mediterranean fauna. With the presented SEM photos of 299 species in 84 plates, the aim of the present Atlas is to fill the gap and provide an updated checklist of foraminiferal fauna of the Turkish coastline, representing the majority of the Levantine Basin.

Published: May 2022

Taxonomic revision of deep-sea Ostracoda from the Arctic Ocean was conducted to reduce taxonomic uncertainty that will improve our understanding of species ecology, biogeography and relationship to faunas from other deep-sea regions. Fifteen genera and 40 species were examined and (re-)illustrated with high-resolution scanning electron microscopy images, covering most of known deep-sea species in the central Arctic Ocean. Seven new species are described: Bythoceratina lomonosovensis n. sp., Cytheropteron parahamatum n. sp., Cytheropteron lanceae n. sp.,Cytheropteron irizukii n. sp., Pedicythere arctica n. sp., Cluthiawhatleyi n. sp., Krithe hunti n. sp. This study provides a robust taxonomic baseline for application to paleoceanographical reconstruction and biodiversity analyses in this climatically sensitive region.
Bulbobaculites gorlicensis n. sp. – a new agglutinated foraminifera from Eocene of flysch Carpathians
Authors: Waskowska Anna
Published: May 2022

A new foraminiferal species, Bulbobaculites gorlicensis n. sp., is described from the Bartonian (Middle Eocene) succession of the Hieroglyphic beds deposited in the Silesian Basin, Outer Carpathians (South Poland). It occurs in association with deep-marine bathyal and abyssal assemblages dominated by agglutinated forms. The test of Bulbobaculites gorlicensis is relatively large, free, and elongated, consisting of 3-4 spherical chambers quickly increasing in size and composed of coarse quartz sand grains. The initial part of the test is in low trochospiral coil, terminally uniserial with terminal aperture on the last, largest chamber.
Prymnesium neolepis (Prymnesiaceae), a siliceous Haptophyte from the Southern Indian Ocean
Authors: Patil Shramik , Mohan Rahul , Shetye Suhas , Gazi Sahina , Jafar Syed A.
Published: May 2022

Prymnesium neolepis was collected from surface and sub-surface waters of the Southern Indian Ocean. It is characterized by the presence of broad 0.6 ym-1ym, recurved poreless brim (collar), and small sized numerous pores (0.1-0.2ym size, 180-240 pores) in the bulging central area of hat-shaped siliceous scale. It was observed in the subtropical and subantarctic frontal regions (0-110m depth) and in surface waters up to 60°S. It is neither recognizable in the fossil record nor bottom sediments and also shows close affinity with siliceous scales of extant Petasaria heterolepis. Further studies focusing on culture, accessory pigments and phylogenetic-molecular aspects could reveal better understanding of this rare siliceous and other unmineralized scale bearing Haptophyte.
Late 20th Century benthic foraminiferal distribution in Central San Francisco Bay, California: Influence of the Trochammina hadai invasion
Authors: McGann Mary
Published: May 2022

The distribution of foraminifera in most of San Francisco Bay is well documented, but this is not the case for the subembayment known as Central Bay. To resolve this, 55 grab samples obtained in 199 were analyzed to characterize the foraminiferalfauna in the surface sediments of the area. Thirty-five species were identified, including the invasive Japanese species Trochammina hadai that was introduced into the bay in the early 1980s. A cluster analysis of the samples from Central Bay produced three groups (biofacies) and one outlier. The Shallow Subtidal Biofacies is characterized by a marsh to shallow-subtidal agglutinated fauna, dominated by T. hadai but also including T. inflata, T. macrescens, Haplophragmoides subinvolutum, and Miliammina fusca. The Intermediate Subtidal Biofacies, the Intermediate Subtidal Outlier, and the Deep Subtidal Biofacies are dominated by calcareous taxa, most notably Ammonia tepida, Elphidium excavatum, and Elphidiella hannai. Ammonia tepida is most abundant in the warmer, intermediate depths of eastern Central Bay, abundances of E. excavatum peak in the cooler estuarine water near Alcatraz Island, and E. hannai thrives in the cold water west of Angel Island in a transitional setting between the deep subtidal estuarine and the nearshore marine environments. The recovery of oceanic species as far east as Angel Island indicate that western Central Bay is the most marine-influenced region of San Francisco Bay. Samples collected from 1965 onward were also compared with those from 1998 to investigate how the distribution of benthic foraminifera in Central Bay has changed over the latter half of the 20th Century, particularly in response to the invasion by Trochammina hadai. In 1998, T. hadai was recovered at 46 of 55 sites in Central Bay, comprising from 0.3 to 97% (mean = 23%) of the foraminiferal fauna. With the species’ affiliation for shallow environments, it is not unexpected that it dominated the fauna of the Shallow Subtidal Biofacies (68-97%, mean = 77%) and was also a significant component of the Intermediate Subtidal Biofacies (7-51%, averaging 28%). In the deeper waters west of Alcatraz Island, the abundance of T. hadai was significantly less (mean = 8%), most likely reflecting allochthonous specimens that were the result of post-mortem transport. A cluster analysis clearly distinguishes pre- and post-invasion biofacies, illustrating how dominant T. hadai has become in Central Bay.

Published: May 2022

Pteropods and heteropods (holoplanktonic gastropods) are an important component of the modern oceans; however, detailed information on their distribution in the fossil record is often based on poorly preserved specimens. This study presents the micropaleontological analysis of three exceptionally well-preserved Late Pleistocene marine sediment cores from the eastern Caribbean Sea, western Mediterranean Sea and the Indian Ocean. This study presents the first stratigraphical record of heteropods in the Caribbean Sea and extends the known zonation of pteropods in the Mediterranean Sea. Distributions of pteropods, heteropods and planktonic foraminifera are presented with abundance and species richness data, as well as stratigraphical dates inferred from the oxygen isotope stratigraphy, argon-argon dating and biostratigraphy. The findings of this study greatly improve our understanding of holoplanktonic gastropod stratigraphy and ecology. Results reveal that the geographical range of heteropods, thought to be restricted to sub-tropical warm waters, may be much greater, including waters of sub-polar temperature. Heteropods were also found to be surprisingly abundant, potentially representing a more important part of the ocean food web than previously thought. Analysis revealed two species of holoplanktonic gastropod that are previously undescribed and indicate that the pteropod Heliconoides mermuysi (Cahuzac and Janssen 2010), known exclusively from the Moulin de Cabanes (Miocene), may have lived in the Caribbean Sea and Indian Ocean as recently as 4 kyr ago. These findings highlight the urgent need for increased research on holoplanktonic gastropods. The threat that current climate change and ocean acidification poses, particularly to the delicately shelled forms, means that some species may become extinct before they have even been fully ‘discovered'.
Abrupt Quaternary Ocean-ice Events in the Arctic: Evidence from the Ostracode Rabilimis
Authors: Cronin Thomas M. , Gemery Laura , Olds Baylee M. , Regnier Alexa M. , Poirier Robert K. , Sui Sienna
Published: May 2022

The Arctic Ocean has experienced orbital and millennial-scale climate oscillations over the last 500 kilo-annum (ka) involving massive changes in global sea level and components of the Arctic cryosphere, including sea-ice cover, land-based ice sheets and ice shelves. Although these climate events are only partially understood, micropaleontological studies utilizing ostracodes and benthic foraminifera have demonstrated that major changes in faunas have occurred at different timescales that signify ecosystem regime changes linked to sea-ice cover, surface productivity, bottom temperature and other factors. In addition to faunal changes characterizing glacial-interglacial cycles, Arctic sediments contain several unusual faunal events that cannot be explained by orbital-scale sea level and cryospheric changes. One indicator of such events involves the ostracode Rabilimis mirabilis (Brady 1868), a shallow-water species that inhabits continental shelves in the modern Arctic. We conducted studies of the stratigraphic distribution of R. mirabilis in cores from the Northwind, Mendeleev, Lomonosov, and Alpha Ridges; the Siberian and North American (Beaufort Sea) continental margins; and the Lincoln Sea off North Greenland and in the northern Greenland Sherard Osborn Fjord. Evidence from these records suggests that this species occurs as a fossil in deeper water sediment cores on the upper parts of submarine ridges (mainly 700-900 meters water depth, mwd), in significant numbers (from 1%to 50% of total ostracodes) during Marine Isotope Stages (MIS) 5a (125-109 ka), MIS 4 (71-57 ka), and MIS 3 (57-29 ka). Furthermore, it occurs in cores from various depths on the Siberian margin, the Beaufort and Lincoln Seas during MIS 1 (the Holocene, approx. 11-0 ka). These occurrences involve well-preserved, stratigraphically consistent adult and juvenile populations, which are autochthonous in nature and not caused by downslope transport or ice rafting. Based on their age and associated paleoceanographic conditions in the Arctic, we interpret these R. mirabilis events as signifying basin-ward migration during abrupt changes in growth and decay of massive ice shelves and may be useful as biostratigraphic markers.
Poseidonamicus (Ostracoda) from the North Atlantic Ocean
Authors: Huang Huai-Hsuan May , Yasuhara Moriaki , Cronin Thomas M. , Okahashi Hisayo , Hunt Gene
Published: May 2022

Poseidonamicus is one of the most intensively studied genera among marine fossil ostracods due to its common occurrence in the world deep oceans and its distinctive morphological features. Many studies using Poseidonamicus have contributed to our understanding in a wide range of research topics, from evolutionary developmental biology to paleoenvironmental reconstruction. However, taxonomic confusion with Poseidonamicus species remains widespread because of subtle interspecific differences within this genus and limited taxonomic work on deep-sea faunas. The objectives of this paper are to update taxonomic information about Poseidonamicus species in the Plioceneâ€“Quaternary North Atlantic, and to summarize paleobiogeographical distribution of all known Poseidonamicus species.We describe one new species, Poseidonamicus parasculptus n. sp., and present high-resolution scanning electron microscope images of North Atlantic Poseidonamicus major for the first time. Our distributional compilation shows that many Poseidonamicus species are confined to either the Indo-Pacific, theAtlantic, or the Southern Oceans. This information may provide identification guidance for future regional studies.

Published: May 2022

With the advent of Covid-19, the educational system in Nigeria was thrown into comatose as education at all levels was shutdown to curtail the spread of the virus. The closure lasted for a period of time while disrupting the academic activities across the country. Though, the Federal Government directed all tertiary institutions to switched to virtual teaching and learning as alternative form of learning for the achievement of educational programmes, the transition was slow due to the unpreparedness of Nigerian education system among other factors. To this end, this opinion paper proposes technoducation model which incorporates various technological innovations for enhancing access to higher education in Nigeria. Also, it x-rays the challenges constraining technoducation in expanding access to higher education in post Covid era.

Published: May 2022

Nigeria Colleges of Education have been conducting regular and steady internal assessments in order to determine the progress of learning and strengths of students achievement via continuous assessment. This study correlate the performance of internal assessment termed continuous assessment with the final assessment scores called semester examination in Mathematics courses in Colleges of Education in South-west, Nigeria. Ten public colleges of education in south-west, Nigeria comprising of four federal colleges of Education and six state Colleges of Education were randomly sampled for the study. The instruments were pilot tested and the reliability indices attained were r=0.87, r=0.91, r=0.92 and r=0.90 using Crombach Alpha statistical instrument. Researcher-designed questionnaire and the last three years results in Mathematics courses were the instruments that were employed for the collections of data. Three research questions and two hypotheses were formulated and guided the study. The results showed that there was no significant relationship between continuous assessment and final examination grade scores of students in mathematics based on gender. However, there was significant relationship between continuous assessment and final examination grade scores of students in mathematics based on institution ownership. Among others, it was recommended that high premium should be given to continuous assessments irrespective of students’ gender and institution ownership. Also, intensive seminar should be conducted for lecturers in Nigerian colleges of education on the relevance and impact of continuous assessment in determining students’ academic strengths and progress for making better decision.

Nowadays, mental stress is posing a threat to people's health. People are becoming increasingly stressed as the speed of life quickens. It is difficult to recognise consumers' stress early enough to safeguard them. Because of the popularity of web-based social networking, people are accustomed to sharing their daily activities and communicating with friends via web-based networking media platforms, allowing for the use of online social network data for stress detection. We discovered that a user's stress level is closely related to that of his or her social media friends in our system, and I used a large-scale dataset from real-world social platforms to comprehensively investigate the relationship between user stress levels and social interactions. In our system, we discover that a user's stress level is closely related to that of his or her social media friends, and we use a large-scale dataset from real-world social platforms to comprehensively investigate the link between user stress levels and social interactions. After defining a collection of stress-related textual, visual, and social variables from multiple perspectives, I suggested a system for doing sentiment analysis of Facebook posts using SVM after topic formation. We can determine whether or not a user is stressed. After determining whether or not users are stressed, a hospital advice can be made on a map, and the administrator can send an email with a precaution list to the user so that they can live a healthy and happy life.

Authors: Chigurupati Pragnya , Barathi G. , Arulappan T. , Rajendiran S. , D'Cruze Lawrence , Susruthan M.
Published: May 2022

Introduction and Aim: Diagnosis of gastric cancer continues to remain a challenge, considering the widespread prevalence of precancerous lesions. The local progression and systemic spread are significantly influenced by tumor angiogenesis and lymphangiogenesis. This study aimed to evaluate the immunohistochemical expression of VEGF and  its relationship to tumor grade and stage.
 
Materials and Methods: This cross sectional study was carried out among 30 patients with gastric carcinoma. The specimens were fixed in buffer formalin, embedded in paraffin, sections were stained with Hematoxylin–Eosin and immunohistochemistry was performed for VEGF as per the standard operating procedure. Evaluation was performed using the VEGF score, based on the intensity of reaction and percent of positive cells.
 
Results: The reaction for VEGF was positive in 27 from 30 cases (90%). VEGF expression was observed in the cytoplasm of tumor cells, with granular pattern. A strong correlation was found between VEGF expression and lymph node status and grade of the primary (p value <0.014), but not with the stage of the tumor.
 
Conclusion: VEGF over expression has significance with respect to only site and grade of the tumor and hence the usefulness of targeted therapy in such cases has to be evaluated by molecular studies.
PD-L1 expression in gastric carcinoma – a biomarker for immunotherapy
Authors: Menon Dhanya , Sekhar Ganthimathy
Published: May 2022

Introduction and Aim: Immunotherapy is now being widely used for targeted therapy in several cancers. The PD-1/ PD-L1 (programmed cell death receptor/programmed cell death ligand) axis inhibits the expansion of tumour specific T cells and prevents the immune response against tumours. PD-L1 expression is seen in many cancers including gastric carcinomas and anti PDL1 antibodies are being used to produce tumour regression. This study was done to evaluate PD-L1 expression in gastric carcinomas and correlate this with the different histological types, grades and stages of these tumours
 
Materials and Methods: In this study, 50 cases of gastric adenocarcinoma were analysed for PD-L1 expression using immunohistochemistry. PD-L1 expression was correlated with histopathological factors including histological type, differentiation, grade and stage using statistical methods.
 
Results: A positive PD-L1 expression was observed in 52% of the cases. A positive correlation between PD-L1 positivity and tumour depth to which the tumour was invading the stomach was observed. No correlation was noted with expression of PD-L1 and histological type, differentiation, histological grade and presence/absence of nodal metastasis.
 
Conclusion: PD-L1 expression was seen in more than half of the patients in our study. Hence it is suggested that anti PD-L1 inhibitors can be used as an adjunct in the treatment of gastric cancers, especially those with a greater depth of invasion.

Published: May 2022

Introduction and Aim: Fever patterns in various infections can give important clues in arriving at an early diagnosis. As most recordings of temperature are not continuous the full utility of this parameter has never been given its due importance. The infections that occur in HIV individuals have varied presentations and hence leads to a delay in its diagnosis and necessitating many investigations. If 24 hours’ temperature monitoring could give reliable patterns of temperature in these various diseases, it would be an inexpensive tool that could be used in these patients as the initial diagnostic approach of these patients.
 
Materials and Methods: In this study on patients with HIV and fever, continuous tympanic temperature monitoring was done. The visual characteristics patterns were compared with the various categories of infections that occurred in these HIV individuals. Results were expressed using mean (standard deviation), median (inter quartile range) and proportion. ANOVA was used to find the statistical difference between various opportunistic infections and a P value <0.05 was considered to be statistically significant.
 
Results: A total of 65 HIV patients were included in the study. The type of jerky temperature pattern could differentiate between bacterial, intracellular, tuberculosis and parasitic infections (Pearson Chi-Square =16.4, P= 0.058). The type of plateau phase could also distinguish these categories of diseases. The Pearson Chi-Square value for plateau phase was 10.511 with p-value 0.015.
 
Conclusion: When these temperature patterns were applied for diagnosing the various categories of diseases in HIV their accuracies were as follows: For bacterial diseases (62.5%); intra-cellular (50%); tuberculosis (82.1%); parasitic (64.3%). The overall accuracy was 71%, showing that the temperature patterns could be used as an important starting point in the diagnostic approach in these patients.

Signaling Sustainability: Exploring Consumer Perspectives on Communicating Apparel Sustainability Information
Authors: Williams Annie , Hodges Nancy
Published: May 2022

The fashion industry is characterized by unsustainable production and consumption. However, a consistently noted barrier to sustainable and responsible apparel consumption is a lack of consumer knowledge. A potential solution to mitigate this barrier is to use apparel labeling to signal the sustainability of an item to consumers. Thus, the purpose of this study is to employ signaling theory to explore the aspects of sustainability that resonate with consumers and why, the modes of communication preferred by consumers, and how such information would affect their apparel consumption decisions. In-depth interviews were conducted with a diverse sample of twenty participants. Analysis of the data resulted in the identification of three emergent themes related to communicating information about sustainability that were used to structure the interpretation: Its Importance is Relative, Signal Mode vs. Message, and Increasing the Interest Level. Overall, participants preferred simple, yet detailed messages on apparel labels to communicate aspects of an apparel item’s sustainability. Ultimately, such labeling signals sustainability to consumers, enabling them to differentiate between sustainable and unsustainable apparel.
Minimizing Packet Drop Due to Black Hole Attack in Wireless Ad-Hoc Network Using Intrusion Detection System

Published: May 2022

A black hole attack is a place in computer networking whereby incoming and outgoing traffic are silently discarded or dropped without notifying the source that the data sent was unable to reach its destination. A highly successfully black hole attack can prevent all data from reaching its destination and are undetectable. This attack is a significant threat to any wireless Ad-hoc Network because it causes isolation in the Network and does that untraced. The aim of this research work focus on minimizing black hole attack in wireless Ad-hoc Network. To do this, the effect of black hole attack on wireless Ad-hoc Network in terms of packet delivery ratio was first determined. This was done by comparing the packet delivery ratio when intrusion detection system was activated and when it was not activated. Next was to reduce the rate of packet loss as a result of black hole attack this was achieved by generating a packet transmission scheme, which will enable the nodes to gain authentication in the network before packets will be sent to them, thereby reducing the rate of packet loss. After this an intrusion detection system was implemented in all the node. Then a sequence number model and Wi-Fi mini point adapter method was used in modeling intrusion detection system and the corresponding throughput was achieved by calculating the amount of data transferred from source to destination in a given amount of time. All the above work was performed by simulation using PHP-MYSQL and MATLAB. The results obtained showed that the packet loss in ad-hoc wireless network under attack was reduced by 1% when compared by the work done by other researchers.

A mobile application, sometimes known as an app, is a form of software designed to operate on a mobile device such as a mobile phone or tablet and is commonly used to deliver user services similar to those accessible on PCs. Mobile applications have become an important part of our lives, allowing us to communicate with people all over the world while sitting at home. However, these applications do more than just connect people; they also provide information, entertainment, and a way to learn new things at any time and from any location. Mobile application testing is very important before releasing any apps. However, since multimode mobile platforms such as handsets, smartphones, tablets, pads, and wearable electronics are now available, various device fragmentations, iOS platforms, and various customer specifications, mobile application testing has recently become incredibly challenging. This article provides an overview of several mobile testing approaches as well as the most recent mobile app testing challenges. In addition, we provide a testing cycle in which mobile apps are sent to clients for feedback. In this article, we also performed a survey of current mobile app users on various bugs in real-world mobile applications, which will be used as a factor in future development.
