This article is the second in a two-part series that analyzes current research on harassment in archaeology. Both qualitative and quantitative studies, along with activist narratives and survivor testimonials, have established that harassment is occurring in archaeology at epidemic rates. These studies have also identified key patterns in harassment in archaeology that point to potential interventions that may prevent harassment, support survivors, and hold perpetrators accountable. This article reviews five key obstacles to change in the disciplinary culture of archaeology: normalization, exclusionary practices, fraternization, gatekeeping, and obstacles to reporting. Two public health paradigms—the social-environmental model and trauma-informed approaches—are used to identify interventions that can be taken at all levels of archaeological practice: individual, relational, organizational, community, and societal.

Our aim is to give a representation of the modal contribution of sentence adverbs in comparison to other forms conveying modal meaning, such as tenses and modal verbs. Our analysis will focus on modal sentence adverbs conveying epistemic meaning. These will be compared with the modal verbs pouvoir (can) and devoir (must) as well as with some uses of the future tense (called epistemic uses), with the purpose to present a model allowing to apprehend modal meanings transmitted by lexical and grammatical forms in order to differentiate their functioning. We will then substantiate our qualitative analysis by quantitative studies on the collocates that the modal sentence adverbs co-occur with in contemporary corpora constituted of 21st century newspapers, as well as in two other corpora representing two different genres and time periods: Universalis Encyclopedia and the digital edition of the Encyclopedia of Diderot and d’Alembert.

Resumen: En los últimos años se ha avanzado notablemente en el estudio cuantitativo y especialmente cualitativo de la represión de las mujeres durante el franquismo. Se han publicado numerosos testimonios, investigaciones rigurosas e incluso novelas, películas y documentales, a los que hay que añadir actualmente el entorno digital. En este marco, este trabajo plantea un estudio que confronta el estado de la cuestión en la historiografía con su presencia en las plataformas sociales a fin de comprobar el tratamiento que se le confiere en el contexto de las expresiones digitales de la represión franquista.Palabras clave: Represión de mujeres, represión franquista, historia digital, historia pública digital, redes de relatos.Abstract: In recent years has advanced greatly in qualitative and quantitative studies about women repression during the Franco regime. In addition to the publication of several testimonies, there are rigorous research on the Francoist prisons for women, and novels, films and documentaries. Along with these new scenarios of diffusion, the digital environment currently sets a field where also express and disseminate content of this phenomenon of our most traumatic past. Within this framework, this paper proposes a comparative perspective among the state of arts with the presence of women prosecution in social platforms in order to verify the treatment conferred in the context of digital expressions of the Francoist repression.Key words: women repression, Franco’s repression, digital history, digital public history, network stories.

BACKGROUND Digitalization and the increasing availability of online information have changed the way in which information is searched for and retrieved by the public and by health professionals. The technical developments in the last two decades have transformed the methods of information retrieval. Although systematic evidence exists on the general information needs of specialists, and in particular, family physicians (FPs), there have been no recent systematic reviews to specifically address the needs of FPs and any barriers that may exist to accessing online health information. OBJECTIVE This review aims to provide an up-to-date perspective on the needs of FPs in searching, retrieving, and using online information. METHODS This systematic review of qualitative and quantitative studies searched a multitude of databases spanning the years 2000 to 2020 (search date January 2020). Studies that analyzed the online information needs of FPs, any barriers to the accessibility of information, and their information-seeking behaviors were included. Two researchers independently scrutinized titles and abstracts, analyzing full-text papers for their eligibility, the studies therein, and the data obtained from them. RESULTS The initial search yielded 4541 studies for initial title and abstract screening. Of the 144 studies that were found to be eligible for full-text screening, 41 were finally included. A total of 20 themes were developed and summarized into 5 main categories: <i>individual needs</i> of FPs before the search; <i>access needs</i>, including factors that would facilitate or hinder information retrieval; <i>quality needs</i> of the information to hand; <i>utilization needs</i> of the information available; and <i>implication needs</i> for everyday practice. CONCLUSIONS This review suggests that searching, accessing, and using online information, as well as any pre-existing needs, barriers, or demands, should not be perceived as separate entities but rather be regarded as a sequential process. Apart from accessing information and evaluating its quality, FPs expressed concerns regarding the applicability of this information to their everyday practice and its subsequent relevance to patient care. Future online information resources should cater to the needs of the primary care setting and seek to address the way in which such resources may be adapted to these specific requirements.

Using unbalanced panel data from the small and medium enterprise surveys in 2005, 2007, 2009, 2011, 2013, and 2015, this chapter investigates factors associated with informality in Vietnam. We assume that household businesses, especially the top tier firms, become formal either because they perceive benefits of formalization such as an increase in the household performance, or because they want to escape bribes and harassment. Using the random effects model with controlling for the pre-formalization trends, our results show that productive household businesses stay informal because net costs from tax payment may surpass net benefits from formalization. Moreover, government controls do not promote formalization, especially among the ‘upper’ tiers of informal households. Our findings raise suspicions of collusion corruption between informal households in top tiers and officials. Future steps could be qualitative and quantitative studies to investigate collusion corruption as a determinant of informality in developing countries.

This study focused on benthic algae (epipelic and attached algae on concrete lining stream) in Bani-Hassan stream in Holly Karbala, Iraq. The qualitative and quantitative studies of benthic algae were done by collecting 240 samples from five sites in the study area for the period from December 2012 to November 2013. Also, the environmental variables of the stream were examined in term of temporary and spatial. The results showed that the stream was alkaline, hard, oligohaline and a well aerated. The total nitrogen to the total phosphorus (TN: TP) ratio indicates nitrogen limitation. 129 species of benthic algae belonging to 57 genera were identified. Bacillariophyceae (diatoms) was the predominant taxon (95 species) followed by Chlorophyceae (16 species), Cyanophyceae (14 species), Euglenophyceae (3 species) and Pyrophyceae (one species). Some genera were found throughout the study period: Nitzschia, Navicula, Cymbella, Gomphonema, Surirella, Cocconeis, Aulacoseira, Oscillatoria, Lyngbya, Spirulina, and ? Scenedesmus. Site 3 recorded the highest total number of algae in spring 2013, and the lowest total number was at site 5 in Autumn 2013. The chlorophyll-a concentration did not match the total number of algae.
