Suala la ukame limeanza kupata umakini mwingi kwa sababu ya kuongezeka kwa hivi karibuni kwa marudio na makali yake. Mathalani, ni mwanzo wa maafa yanayoaminika kuwa chanzo cha kimsingi cha baa la njaa kwa ajili ya uharibifu wa mazao. Kadhalika, ni kutokana na makali ya ukame katika mataifa mbalimbali Barani Afrika na ulimwenguni kwa jumla, ambapo kumeibuka mijadala mizito miongoni mwa washikadau mbalimbali wa masuala ya kimazingira kote ulimwenguni. Tangu kuvumbuliwa kwa uwanja wa fasihi mazingira miaka ya tisini, waandishi wa kifasihi wamejihusisha katika masuala ya kimazingira ili kuchangia katika utatuzi wa matatizo yanayotokana na uharibifu wa mazingira. Kwa msingi huu, makala hii inajadili namna watunzi wa tamthilia za Janga la Werevu (Mohamed, 2011) na Majira ya Utasa (Arege, 2015) wamesawiri motifu ya ukame kama suala mojawapo la kimazingira kwa lengo la kuweka wazi chanzo na athari zake katika jamii. Makala hii iliongozwa na nadharia ya Uhakiki wa Kiekolojia iliyoasisiwa na Glotferty (1996). Nadharia hii hujikita katika uchambuzi wa kazi za kifasihi kwa kuonyesha uhusiano na utegemeano baina ya binadamu na mazingira. Utafiti ulifanyiwa maktabani ambapo uteuzi wa sampuli wa kimakusudi ulitumiwa kuteua matini teule. Data ya utafiti ilikusanywa kupitia usomaji wa kina wa matini teule. Kutokana na matokeo ya makala hii, ilibainika kwamba, waandishi wa tamthilia teule wamesawiri suala la ukame kwa namna mbalimbali kwa kuangazia chanzo na athari zake. Hivyo, makala hii imethibitisha kwamba, fasihi ya Kiswahili ni nyenzo muhimu ambayo inaweza kutumika katika kuangazia masuala yanayoathiri jamii. Vilevile, utafiti huu ni muhimu kwa washikadau wote wa masuala ya kimazingira Barani Afrika na ulimwengu kwa jumla.

Authors: Laababid Younes , El Khadiri Karim , Tahiri Ahmed
Published: July 2022

Wearable biomedical devices for recording electrocardiograms (ECG) are becoming more and more popular as they provide clinicians with a comprehensive view of a patient's diagnosis. ECG signals are characterized by low amplitude and are susceptible to many kinds of noise, so high gain and high common mode rejection ratio (CMRR) are essential to suppress them, while ultra-low power low noise (AFE) is used for Analog front-end for ECG signal acquisition, based on a Drive Right Leg (DRL) circuit that combines common-mode feedback with high CMRR and a notch filter band with a cutoff frequency of 50, implemented in CMOS 180 nm technology. According to the simulation results, this front-end circuit can yield a mid-band gain of 50.75 dB at -3dB bandwidth from 100mHz to 100 Hz, a Power Supply Rejection Ratio (PSRR) of 113 dB, and a Common Mode Rejection Ratio (CMRR) of 102 dB, exhibit an input-referred noise (IRN) of 1.47 μVrms from 0.1 Hz to 1kHz，corresponding to a noise efficiency factor (NEF) of 2.74. The AFE consumes 1.08 μW from the 1.8V supply voltage.
How Women’s Community Shape Social Enterprise and it’s Impact?
Authors: Rofiah Chusnul
Published: July 2022

This paper aims to present how the strength of the women's community is to solve the problems of economic and nutritional adversity through social enterprises established by the women's community. Moreover women are described as motivated not by reasons of money but rather by a desire to act as what can only be described as the mother of the community: women exist to help, to build, for others but never for themselves, and are rarely valued or rewarded for they job. The methods used in data collection are observation, interviews, and photo documentation. The analysis refers to the hermeneutic phenomenological approach by Van Manen (2001), which describes that researchers "mediate" between the meanings of different life experiences. The result of this analysis is the identification of the meaning of success for the women's community through social enterprises. The results of the study indicate that in establishing a women's social enterprise and staying focused on impact, it is necessary to include (1) Women's Leadership Style; (2) Identification with the Community; (3) Participation Process: Listening And Collaborative Atmosphere; (4) Networking. The contribution given from this research is in the fields of economics and business, especially in the strategy of establishing social enterprises for women in the third sector. The implication of this research is the selection of a social business establishment strategy and the focus of solving the problems to be solved.

POSIBILIDAD DE APLICACIÓN DE TÉCNICAS DE CORRECCIÓN NO INTERVENCIONISTA PARA ERRORES ORALES A LA ENSEÑANZA DE IDIOMAS
Authors: Estrada Chichón José Luis
Published: July 2022

En el presente trabajo se reflexiona acerca de la ausencia de intervención correctiva como una posibilidad de técnica de corrección per se para errores orales en la enseñanza de idiomas. Esta propuesta encuentra su justificación en los resultados obtenidos tras la aplicación de tres herramientas de investigación (observación de clases, cuestionarios y entrevistas) en un contexto de educación superior. Se registraron diferencias significativas en la gestión docente del tratamiento de errores orales entre cursos de idiomas (ELE) y cursos de contenido (ANL) o de enseñanza bilingüe en español (lengua extranjera). Respecto al tratamiento de errores orales mediante técnicas de corrección intervencionistas, el estudio tiene en consideración dos variables: los tiempos de intervención pedagógica y las propias técnicas de corrección.  Según esta distinción, ambos grupos de profesores optan por intervenir de forma inmediata, lo que conlleva casi necesariamente el uso de técnicas de corrección explícitas. Con todo, para ambos contextos (ELE y ANL) también queda manifiesta la posibilidad de no intervenir sobre los errores orales, sobre todo en los cursos ANL. Por último, se presenta una serie de recomendaciones para profesores de idiomas sobre el tratamiento de errores orales en relación con la posibilidad de aplicar técnicas de corrección no intervencionista.

Influence of Mother-Tongue On English Language Use Selected Mother-Tongue Factors Affecting English Language Usage, A Case Study of Ikom Local Government Area
Authors: Ochagu Kaka A. , Agban Joy Obim
Published: July 2022

Over the years, English Language has been accorded a very high prestige in Nigeria.The status and functions given to English in Nigeria has made it become imperative for every Nigerian citizen to learn how to speak, read and write the language. This is as a result of the pluralistic linguistic situation of Nigeria which has made it impossible for national language. This accounts for why English has been allotted prestigious domains of use in Nigeria. This study was undertaken to investigate and shed more light on the effect that mother-tongue influence has on spoken English in Nigeria. The focus of this study is on selected mother-tongue factors affecting English language in Nigeria. In order to manipulate variables properly to achieve tenable results, this study will focus on the phonetic and phonological levels of mother-tongue interference. 150 Ikom learners/users of English were sampled from SSS3 students selected from three secondary schools in Ikom Local Government Area, Cross-River State, where Ikom is their native language. Tape recorders and smart recorders were instruments of data collection alongside (phonetic) articulation tests. The technique employed in the analysis of data was descriptive and quantitative. The sources of data were relevant textbooks, magazines, journals, libraries (online and offline) and the internet. The findings revealed that, the mother-tongue of Ikom learners/and users of English negatively influences their spoken English, significantly in their articulation of English consonants, vowels and consonant clusters; and suprasegmentals such as stress and intonation.

Published: July 2022

В статье приведен анализ применения светодиодного освещения животноводческих помещений, которое может быть не только энергоэффективным, но и помочь увеличить продуктивность ферм. Сельское хозяйство является крупнейшим потребителем электрической энергии в виде оптического излучения. Рациональное использование и экономия электроэнергии в осветительно-облучательных установках имеет громаднейшее значение в общем балансе электропотребления. Продукцией осветительно-облучательных установок в сельском хозяйстве является поток, создающий требуемую освещенность для выполнения зрительных работ, либо ультрафиолетовую облученность для воздействия на животных с целью сохранения и повышения продуктивности. Затратами являются капитальные единовременные затраты на осветительные установки (оборудование, монтаж) и эксплуатационные расходы на содержание осветительно-облучательных установок, в первую очередь на замену источников излучения, их чистку, а также на оплату электроэнергии. Учитывая, что стоимость электроэнергии очень сильно возросла, то вопрос о снижении затрат на освещение и облучение имеет большую актуальность. Таким образом, задача осветительно-облучательных установок сводится к сокращению как непосредственно капитальных затрат, так и эксплуатационных расходов, т.е. в основном к сокращению расхода электроэнергии и относятся к важнейшим проблемам.

Application of low height noise barriers to reduce railway noise
Authors: Sarpalius Domininkas , Grubliauskas Raimondas
Published: July 2022

Railway noise is growing a global problem and the low height barrier may be the future for reducing noise from railways. Railroads are usually designed in cities, near buildings. Every day, in the European Union, some 12 million people are exposed to railway noise. Long term noise exposure can increase human health problems. At a lower level it may cause lower concentration at work, harder relaxation at home or even in the nature. In the worst cases, noise pollution may contribute to serious health issues including hearing damage, hypertension, headache and insomnia. Low height barriers may have high efficiency, but distance between source and barrier should always be the same. This type of barrier has a limited perspective of usage, one of the best situations – near railways. High barriers usually cover the view, and their installation has a large cost. But there are more disadvantages to high walls: they effect reflection sunlight, and frequently high barriers (which are 5 metres or more) may provoke claustrophobia in drivers while they are passing through. Low height barriers never cover the view, they have half the cost of installation, and may be constructed in a variety of shapes: such as Y, T, pearl, cylindrical, and arrows. The use of low-height barriers involves 50% less investment than high barriers. Low-height barriers effectively contain noise levels, with an effectiveness of 4 dB for a 1-metre barrier and 8 dB for a 2-metres barrier.
Dažiklių šalinimo iš nuotekų eksperimentiniai tyrimai naudojant iš automobilių padangų atliekų pagamintas devulkanizuotos gumos granules

Published: July 2022

Darbe nagrinėjama tekstilės pramonėje naudojamų dažiklių šalinimo iš nuotekų problema. Darbo tikslas – iš automobilių padangų atliekų pagamintų devulkanizuotos gumos granulių naudojimo naftolio žaliojo B dažikliui šalinti iš dirbtinai užteršto vandens galimybių įvertinimas. Eksperimente naudota 1–2 mm dydžio gumos granulių frakcija. Eksperimentiniai sorbcijos tyrimai atlikti siaurame pH verčių intervale, kuris kito nuo 6,0 iki 7,0. Dažiklio sorbcijos procesas tirtas 1 valandą nuolat maišant magnetine maišykle vandeninius dažiklio tirpalus su gumos granulių mėginiais. Tirpalo spalvotumo pokyčiui po sorbcijos įvertinti pasirinktas spektrofotometrinis analizės metodas, matuojant tirpalų optinį tankį, kai bangos ilgis – 484 nm. Prieš atliekant matavimus su fotokolorimetru, sudaryta kalibracinė kreivė. Ištirpusios anglies kiekis vandeniniuose tirpaluose nustatytas naudojant anglies analizatorių „Shimadzu TOC“. Adsorbcijos efektyvumo vertės svyravo nuo 9,88 % iki 94,68 %. Mėginiuose ištirpusios anglies koncentracija po sorbcijos proceso nesumažėjo, nes gumos granulės tapo antrinės taršos priežastimi. Didinant pH reikšmę nuo 6,0 iki 8,5 buvo pastebėta, kad nedaug padidėjo dažiklio naftolio žaliojo B vandeninio tirpalo optinis tankis. Remiantis rezultatais galima manyti, jog tirpalo pH pasikeitimas po sorbcijos proceso neturėjo reikšmingos įtakos procesui.

Diffusion Activation Energy and Desorption Activation Energy for Astrochemically Relevant Species on Water Ice Show No Clear Relation
Authors: Furuya Kenji , Hama Tetsuya , Oba Yasuhiro , Kouchi Akira , Watanabe Naoki , Aikawa Yuri
Published: July 2022

The activation energies for desorption (E
des) and for surface diffusion (E
sd) of adsorbed molecules on dust grains are two of the most important parameters for the chemistry in the interstellar medium. Although E
des is often measured by laboratory experiments, the measurement of E
sd is sparse. Due to the lack of data, astrochemical models usually assume a simple scaling relation, E
sd = f
E
des, where f is a constant, irrespective of the adsorbed species. Here, we experimentally measure E
sd for CH4, H2S, OCS, CH3OH, and CH3CN on water-ice surfaces using an ultrahigh-vacuum transmission electron microscope. Compiling the measured E
sd values and E
des values from the literature, we find that the value of f ranges from ∼0.2 to ∼0.7, depending on the species. Unless f (or E
sd) for the majority of species is available, a natural alternative approach for astrochemical models is running multiple simulations, varying f for each species randomly. In this approach, ranges of molecular abundances predicted by multiple simulations, rather than abundances predicted by each simulation, are important. We here run 10,000 simulations of astrochemical models of molecular clouds and protostellar envelopes, randomly assigning a value of f for each species. In the former case, we identify several key species whose E
sd most strongly affects the uncertainties of the model predictions; E
sd for those species should be investigated in future laboratory and quantum chemical studies. In the latter case, uncertainties in the E
sd of many species contribute to the uncertainties in the model predictions.

Published: July 2022

BACKGROUND: Inflammatory bowel disease (IBD) diagnosis remains a challenge accompanied with high numbers of misdiagnosis causing suboptimal management. Tons of trials have been conducted to improve the diagnostic accuracy, one of which is the use of biomarker such as calprotectin. Calprotectin can be detected in tissue (intramucosal) and is becoming a potential marker of IBD. AIM: This study aims to determine intramucosal calprotectin expression in IBD, non-IBD colitis, and control. METHODS: This analytic retrospective study included consecutively sampled IBD and non-IBD colitis colorectal biopsy specimens, and control group obtained from Cipto Mangunkusumo Hospital registered from 2017 to 2019. Cases were included in the study if specimens were indicative of IBD and non-IBD clinically and histopathologically and no abnormality were found histopathologically in the control group. Specimens with non-adequate data from the hospital medical records or with missing tissue slides were excluded from the study. Calprotectin immunostaining was conducted to evaluate mean intramucosal calprotectin expression (cell/HPF) in each group. RESULTS: Most of the samples from IBD and non-IBD group (45 samples each) showed mild active inflammation. Mucosal calprotectin expression in aforementioned groups was higher than that of control group (p < 0.001). Subjects with active inflammation showed higher calprotectin expression compared to those with inactive inflammation (p < 0.001). Calprotectin expression was also related to activity grade. CONCLUSION: Higher calprotectin expression showed significant association with the presence of inflammation and disease activity. However, the application of intramucosal calprotectin immunohistochemistry test to determine inflammatory etiology (IBD vs. non-IBD) still needs to be further evaluated.
Les réfugiés LGBTI
Authors: Hamila Ahmed
Published: July 2022

Depuis la reconnaissance des persécutions du fait de l’orientation sexuelle et de l’identité de genre en tant que motif d’octroi du statut de réfugié en France et au Royaume-Uni, on a vu apparaître une nouvelle catégorie d’action publique au sein des autorités asilaires de ces pays : les réfugiés LGBTI. Cette catégorie d’action publique se matérialise par des instruments spécifiques qui ont été mis en place pour le traitement des demandes d’asile liées à l’orientation sexuelle et l’identité de genre et notamment pour établir la crédibilité de ces requérants. S’inscrivant dans une approche socio-historique de l’analyse de l’action publique, cet article retrace l’émergence de cette nouvelle catégorie d’action publique en s’intéressant aux acteurs administratifs, associatifs et judiciaires du droit d’asile ainsi qu’à leurs logiques interprétatives. J’y démontre que bien que censée représenter le même groupe d’individus, la catégorie de réfugiés LGBTI n’a pas connu la même trajectoire de traduction en France et au Royaume-Uni, ce qui s’explique notamment par un paradigme de traduction propre à chaque pays.
Making the most use of boredom in organisations: A study of the ambivalent nature of boredom in business meetings
Authors: Simon Thomas
Published: July 2022

Les réunions sont essentielles pour structurer l’espace social à tel point qu’elles se sont imposées dans le paysage managérial comme lieux privilégiés de diffusion d’informations et de prise de décision. Que ce soit par tradition, par élan de management participatif ou par absence d’alternative, les réunions sont là, s’accumulant parfois jusqu’à l’excès pathologique de la « réunionite ». Alors que nombreux sont ceux qui attaquent les réunions en questionnant leur utilité ou leur efficacité, cet article vise à étudier le vécu de ces réunions par leurs participants. Souvent inévitable, du moins en partie, l’ennui est un des principaux états affectifs qui surgit dans les réunions mal gérées. Dans cet article, l’ennui est notamment envisagé du point de vue de ses conséquences potentielles, qui vont au-delà d’un simple impact sur l’efficacité de la réunion elle-même. En nous appuyant sur des entretiens avec leurs participants dans des cadres organisationnels divers, cette recherche nous permet d’avancer trois contributions. Premièrement, en identifiant les différentes conditions d’apparition de l’ennui en réunion, on développe une approche de l’ennui vécu, dépassant ainsi son caractère tabou qui reste difficile à avouer et encore plus à verbaliser. Deuxièmement, on met en lumière le caractère profondément ambivalent de l’ennui : lorsque l’ennui est ressenti pendant de longs moments, il devient néfaste et destructeur alors qu’en advenant sur de courtes périodes, l’ennui se fait moment de respiration et de créativité. Ensemble, ces deux points nous permettent troisièmement de tirer des implications managériales pour proposer un « bon usage de l’ennui » dans la conduite des réunions.
Effets de l’onboarding à distance sur la socialisation organisationnelle : une étude comparative sur les nouveaux entrants d’une ecole de management hôtelier
Authors: de Boer Charlotte , Delobbe Nathalie
Published: July 2022

Cette étude s’intéresse aux effets de l’onboarding à distance vécus par les nouveaux entrants d’une école de management hôtelier pendant la pandémie de Covid-19 et aux ressources mobilisables pour y faire face. En comparant deux cohortes de 200 nouveaux entrants, l'une enrôlée avant la pandémie de Covid-19 et la seconde démarrant dans un fonctionnement organisationnel largement à distance, elle met en évidence les effets délétères de l'onboarding à distance sur la satisfaction, l'épuisement émotionnel et l'intention de poursuivre, mais pas sur l'identification et l'implication organisationnelle. Les conditions d'entrée modulent les effets bénéfiques des comportements proactifs, dans la mesure où ces derniers sont moins profitables lorsque le processus de socialisation se fait à distance. Notre étude montre enfin que les comportements proactifs médient la relation entre l'expression de soi versus le conformisme de façade et les indicateurs d'ajustement au travail. Cette étude offre des pistes pour minimiser les risques que comporte l’onboarding à distance pour l'organisation et pour les nouveaux entrants.
A multimodal parallel method for left ventricular dysfunction identification based on phonocardiogram and electrocardiogram signals synchronous analysis

Published: July 2022

Heart failure (HF) is widely acknowledged as the terminal stage of cardiac disease and represents a global clinical and public health problem. Left ventricular ejection fraction (LVEF) measured by echocardiography is an important indicator of HF diagnosis and treatment. Early identification of LVEF reduction and early treatment is of great significance to improve LVEF and the prognosis of HF. This research aims to introduce a new method for left ventricular dysfunction (LVD) identification based on phonocardiogram (ECG) and electrocardiogram (PCG) signals synchronous analysis. In the present study, we established a database called Synchronized ECG and PCG Database for Patients with Left Ventricular Dysfunction (SEP-LVDb) consisting of 1046 synchronous ECG and PCG recordings from patients with reduced (n = 107) and normal (n = 699) LVEF. 173 and 873 recordings were available from the reduced and normal LVEF group, respectively. Then, we proposed a parallel multimodal method for LVD identification based on synchronous analysis of PCG and ECG signals. Two-layer bidirectional gate recurrent unit (Bi-GRU) was used to extract features in the time domain, and the data were classified using residual network 18 (ResNet-18). This research confirmed that fused ECG and PCG signals yielded better performance than ECG or PCG signals alone, with an accuracy of 93.27%, precision of 93.34%, recall of 93.27%, and F1-score of 93.27%. Verification of the model's performance with an independent dataset achieved an accuracy of 80.00%, precision of 79.38%, recall of 80.00% and F1-score of 78.67%. The Bi-GRU model outperformed Bi-directional long short-term memory (Bi-LSTM) and recurrent neural network (RNN) models with a best selection frame length of 3.2 s. The Saliency Maps showed that SEP-LVDPN could effectively learn features from the data.

We report the results of 3-years of Radon-222 monitoring in six show caves across Europe, selected with the feature of having only one, or no natural entrance, defined as dead-end caves. The caves are located in Spain, Slovakia, Slovenia, and Czechia. The consecutive monitoring was performed between January 2017 and January 2020. Continuous measurements of the radon activity concentration using spectrometry detection and analysis of the α-particles of 222Rn progeny were performed. Meteorological parameters influencing gas flow were recorded inside and outside of the caves. Although the radon activity concentrations differed from one cave to another, all six of the studied caves revealed very similar trends, showing evident seasonal variability with higher values in summer and lower values in winter. The measured values of radon activity concentrations ranged between 633 and 26,785 Bq/m3. The temperature differences between the inside and outside of the caves is the main radon movements driving force. The results of this study have significant practical implications, making it possible to provide cave administrators with recommendations regarding employee or visitor time-limited access to the investigated caves. Ours is the first comparative study encompassing the most interesting dead-end caves in Europe.
Development and persistence of hazardous atmospheres in a glaciovolcanic cave system—Mount Rainier, Washington, USA

Published: July 2022

Glaciovolcanic cave systems, including fumarolic ice caves, can present variable atmospheric hazards. The twin summit craters of Mount Rainier, Washington, USA, host the largest fumarolic ice cave system in the world. The proximity of fumarole emissions in these caves to thousands of mountaineers each year can be hazardous. Herein we present the first assessment and mapping of the atmospheric hazards in the Mount Rainier caves along with a discussion on the microclimates involved in hazard formation and persistence. Our results are compared to applicable life-safety standards for gas exposure in ambient air. We also describe unique usage of Self-Contained Breathing Apparatus (SCBA) at high altitude. In both craters, subglacial CO2 traps persist in multiple locations due to fumarole output, limited ventilation, and cave morphology. CO2 concentrations, calculated from O2 depletion, reached maximum values of 10.3 % and 24.8 % in the East and West Crater Caves, respectively. The subglacial CO2 lake in West Crater Cave was persistent, with atmospheric pressure as the main factor influencing CO2 concentrations. O2 displacement exacerbated by low O2 partial pressure at the high summit altitude revealed additional cave passages that can be of immediate danger to life and health (IDLH), with O2 partial pressures as low as 68.3 mmHg. Planning for volcanic research or rescue in or around similar cave systems can be assisted by considering the implications of atmospheric hazards. These findings highlight the formation mechanisms of hazardous atmospheres, exploration challenges, the need for mountaineering and public awareness, and the broader implications to volcanic hazard assessment and research in these environments.
Welding a New Approach to the Study of Ancient Metals
Authors: Pearce Mark , Stöllner Thomas
Published: July 2022

Two communities have emerged in archaeometallurgy: the archaeologists, largely educated in the humanities, and the material scientists. Killick (2015; Pearce, 2016) has illustrated the non-communication and mutual lack of interest in the debates between the two traditions, one focused on the social and symbolic aspects of metalwork, the other interested in techniques of analysis and chemical and mineralogical processes. This session aims to build bridges the two approaches, encouraging collaborative research goals, and thereby to fuse the two in a new understanding.
Tin Provenance and Raw Material Supply – Considerations about the Spread of Bronze Metallurgy in Europe
Authors: Nessel Bianka , Brügmann Gerhard , Frank Carolin , Marahrens Janeta , Pernicka Ernst
Published: July 2022

The paper focuses on isotopic data of bronzes from the 3rd and 2nd millennium BC. The sample sets comprise bronzes from hoards, graves, and settlements from Central and Southeastern Europe as well as the Aegean and Mesopotamia. The analytical determination of tin isotopic compositions and a possible use of tin from different ore sources between the Carpathian Basin, the Aegeo-Balkan-Complex and tin bearing regions in Central and Western Europe will be discussed. Since the 2nd millennium bronzes show in general a different isotopic composition than those of the 3rd millennium, the presented analyses indicate a possible reorientation of exchange routes in Europe during the 2nd millennium BC. This is supported by the composition of a few Aegean samples from the turn of the millennia, which have heavier tin isotopic compositions than all other sample sets. This suggests that different tin sources might have been used to manufacture these bronzes.
In Search of Frequency: Glass-induced Metal Corrosion in the Deutsches Bergbau-Museum Bochum
Authors: Schorpp Alexandra , Braun Miriam , Fischer Andrea , Eggert Gerhard
Published: July 2022

Together with humidity and oxygen from the air, electrolytes that form during glass decay can induce corrosion in neighbouring metals. The presence of sodium, potassium, and formate ions on glass leads to the formation of special metal corrosion compounds. The late discovery of this phenomenon in museum collections pointed to its rareness, but a survey in the cultural history collection of the Swiss National Museum discovered the proportion of affected objects was more than 20 %. The question arose whether this is a common phenomenon or if it only occurs in exceptional cases. For a new investigation and for an  independent test on the frequency of this phenomenon, the collection of the Deutsches Bergbau-Museum Bochum (DBM) was selected. The museum has large collections of miners’ lamps and surveying instruments, which exhibit glass-metal contact. In fact, severe cases of corrosion have rarely been detected, but light cases are in the order of 10 %. The compounds identified in the DBM technical heritage collection were the same as those found before in decorative arts collections.

Published: July 2022

This study analyzes the implementation of the KiVa Antibullyiing program in Spain with 10 pioneer schools.
This research has two aims. The first is a preliminary evaluation of the KiVa program’s implementation in the pioneer schools in Spain. To do so, the perceived levels of bullying and victimization have been analyzed through the surveys done anonymously by the students of 10 KiVa schools before and after the program’s implementation. The second is to identify the factors which explain the phenomenon with a view to knowing the background of the victims and the bullies and proposing courses of action. To do so, the school environment (atmosphere in the classroom and in the school), the perception of the students concerning teachers and parents in relation with the phenomenon (attitude, capacity and behavior) and the communication of the victims were analyzed in their environment in the case of bullying. In the empirical study, analyses were performed of the prevalence of bullying before and after the first year of program’s implementation, as well as an analysis of independence and multiple correspondences. This enables identifying the key variables and drawing conclusions about how the children surveyed live out school bullying in the pioneer Spanish KiVa schools, and what aspects should guide other schools interested in preventing bullying.
