Tissue Chemistry

We investigated the impact of watershed liming on elemental concentrations in the shrubs Myrica gale and Chamaedaphne calyculata and the sedge Carex stricta. We analyzed tissues from plants co-occurring in 1-m2 plots in limed and unlimed portions of an Adirondack poor fen for Al, B, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, N, Na, Ni, P, Pb, Se, V, and Zn. Within 2 years of liming, we found higher concentrations of Ca, Ni, and Zn and lower N, Na, and Mn in Chamaedaphne foliage; higher Fe, K, Mg, Ni, Pb, and Zn and lower Co and Mn in Chamaedaphne twigs; higher Mo and lower Al, B, Mn, and Ni in Myrica foliage; higher Al, Cr, and Mo and lower Cd, Mn, and Se in Myrica twigs; and higher Al and lower Co and Cr in Carex foliage. Clearly, each species was unique in its uptake and allocation of elements, which will influence the rate these elements cycle in this watershed after liming. Elements in Carex foliage changed the least after watershed liming, while those in Chamaedaphne twigs changed the most. However, the slow decay of Chamaedaphne litter will likely inhibit the release of accumulated elements, including Ca. Key words: peatlands, poor fens, liming, watershed, tissue chemistry, Adirondacks.

The deciduous N-fixing shrub Myrica gale L. and the evergreen sclerophyllous shrub Chamaedaphne calyculata (L.) Moench sometimes intermingle in small patches in boreal peatlands. The mineral element composition of adjacent plants and plant parts may differ owing to the distinctive morphology and physiology of each species. We compared the elemental composition and allocation patterns of Myrica and Chamaedaphne co-occurring in 1-m2 plots in a western Adirondack peatland. Current foliage and twigs of each species were analyzed for Al, B, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, Se, V, and Zn. Fourteen elements differed significantly among tissues. Chamaedaphne foliage was highest in Al, Mn, and P, and Chamaedaphne twigs were highest in Cu, whereas Myrica foliage was highest in K and Ni, and Myrica twigs were highest in Mo and Zn. Elemental differences were interpreted with respect to possible physiological roles in each species. Additionally, a multivariate discriminant function analysis yielded two canonical variables: (i) a structural – functional component correlated with Al, B, Ca, Cu, Fe, and K that distinguished Myrica from Chamaedaphne, and (ii) a metabolic component correlated with Al, B, Mo, P, and Zn that separated foliage from twigs. Key words: peatland, sclerophylly, nitrogen fixer, tissue chemistry, Chamaedaphne calyculata, Myrica gale.

The majority of plant communities within the peatland near Lake Édouard belongs to the poor fen group. They are containing poor fen species such as <i>Myrica gale</i>, <i>Carex rostrata</i>, <i>Glyceria canadensis</i>, <i>Calamagrostis canadensis</i>, <i>Carex canescens</i>, <i>Carex stricta</i>, <i>Alnus rugosa</i> and <i>Sphagnum subsecundum</i>. Members of these taxa grow in association with a group of marsh species and with <i>Chamaedaphne calyculata</i> and <i>Sphagnum majus</i>, species characteristic of bogs. The soil are of the humisol great group, being well decomposed and relatively rich in nutrient elements but ranging from extremely to strongly acidic. Four new associations are noted: <i>Sphagno-Juncetum brevicaudati</i>, <i>Sphagno-Hypericetum boreale</i>, <i>Sphagno-Glycerietum canadensis</i> and <i>Carici canescenti</i>-<i>Sphagnetum maji</i>. The distribution of vegetation appears dependent on ground relief and, consequently, on the level and quality of water in the peatland.

The Way

Job (Ayyūb) is a byword for patience in the Islamic tradition, notwithstanding only six Qur'anic verses are devoted to him, four in Ṣād (vv.41-4), and two in al-Anbiyā' (vv.83-4), and he is mentioned on only two other occasions, in al-Ancām (v.84) and al-Nisā' (v.163). In relation to the space devoted to him, he could be accounted a ‘lesser’ prophet, nevertheless his significance in the Qur'an is unambiguous. The impact he makes is achieved in a number of ways. One is through the elaborate intertext transmitted from the Companions and Followers, and recorded in the exegetic tradition. Another is the way in which his role and charisma are highlighted by the prophets in whose company he is presented, and the shifting emphases of each of the sūras in which he appears. Yet another is the wider context created by these sūras in which key words and phrases actualize a complex network of echoes and resonances that elicit internal and transsūra associations focusing attention on him from various perspectives. The effectiveness of this presentation of him derives from the linguistic genius of the Qur'an which by this means triggers a vivid encounter with aspects of the rhythm of divine revelation no less direct than that of visual iconography in the Western Tradition.

The Impact

Adolescents experience alarmingly high rates of sexual violence, higher than any other age-group. This is concerning as sexual violence can have detrimental effects on teens’ personal and relational well-being, causing long-term consequences for the survivor. Still, adolescents are hesitant to report the assault or seek out services and resources. When an adolescent survivor does seek out services, they may interact with a provider who is a mandatory reporter. This scoping review sought to synthesize the current U.S.-based research on the role, challenges, and impact of mandatory reporting (MR) in the context of adolescent sexual assault. Database searches using key words related to MR, sexual assault, and adolescence identified 29 peer-reviewed articles. However, none of these articles reported on empirical investigations of the phenomenon of interest and instead consisted of case studies, commentaries, and position papers. The scoping review was expanded to provide a lay of the land of what we know about the intersection of adolescent sexual assault and MR. Results of the review indicate that though implemented broadly, MR policies vary between individuals, organizations, and states and have historically been challenging to implement due to this variation, conflicts with other laws, tension between these policies and providers’ values, and other factors. Based on the available literature, the impact of MR in the context of adolescent sexual assault is unknown. There is a critical need for research and evaluation on the implementation and impact of MR policies, especially in the context of adolescents and sexual violence.

Abstract This project focuses on the conflict in Indian administered Jammu and Kashmir (J&K). This conflict is characterised by the militarised occupation of the region and resistance for self- determination by indigenous populations. In 2019, there were over 500,000 military and police force stationed in the state of J&K and over the years the forces have become a permanent fixture of the day-to-day life of people in the region. The use of civilian infrastructure by the military apparatus to control the rhythms of everyday life has evolved to its current form as an integral aspect of the conflict itself. This paper is focused on two interrelated aspects i.e., the impact of militarisation, magnified by Covid-19 pandemic on the fieldwork itself and its relationship to the larger impact of militarisation on everyday life in Srinagar. The methodology is inspired by rhythmanalysis which focuses on space of interaction. The rhythmanalysis is in two parts, it explores the rhythms as viewed and investigated by the researcher as opposed to the rhythms of everyday life for research participants. The aim here is to contextualise the questions of ethics and positionality as a researcher, conducting fieldwork during covid 19, in a militarised conflict region.

Abstract Objectives: to identify bibliographically disorders related to excess weight, dyslipidemia and their complication during pregnancy and in the fetus and newborn. Methods: a systematic review including observational and interventional studies and reviews, based on MEDLINE, LILACS, Embase and the Cochrane Library between 2000 and 2015. The key-words "lipids, pregnancy, obesity and newborn" were used to establish a selective stage for inclusion/exclusion of titles, repeated studies, key-words, abstracts, methodological incompatibility and correlation with objectives. Results: 58 studies were selected, of which 36 (62%) addressed prevention and the risk in pregnancy of excess weight and lipid disorders and 19 (32.7%) suggestions and/or consequences for the fetus and newborn. Conclusions: excess weight and lipidemic disorders in pregnancy are causes for concern in scientific studies, posing risks both for the mother and the newborn. Higher prevalence of caesarian and pre-eclampsia were the two most noteworthy complications for gestational outcomes. In short, the impact on care of maternal habits and excess weight during pregnancy is highly significant, owing to the different degrees of complication in obstetric outcomes and their influence on the clinical characteristics of the newborn.

  La investigación de mercados resulta beneficiosa en diversas situaciones; sin embargo, la decisión de realizarla no es automática, esta decisión debe sustentarse en consideraciones previas de muchos aspectos, entre los cuales se puede mencionar, la comparación entre costos y beneficios, los recursos disponibles para realizarla y para llevarla a la práctica, así como la actitud de la gerencia hacia su realización. Por lo cual, debería efectuarse cuando el valor de la información que se genera, supera los costos de llevarla a cabo. Cuanto más importante sea la decisión frente a la que se enfrenta la administración y mayor sea la incertidumbre o el riesgo que ésta implica, mayor será el valor de la información obtenida. La investigación de mercados, suele realizarse, por empresas comerciales que son organizaciones independientes (proveedores externos) o departamentos dentro de las corporaciones (proveedores internos). La motivación en las utilidades en ocasiones hace que los investigadores o los clientes pongan en riesgo la objetividad o profesionalismo asociados con el proceso. Como investigadores, esto despierta nuestro interés y mediante encuestas realizadas en varias empresas dentro de la provincia de Manabí, se pretende dar a conocer el impacto que genera la investigación de mercados en la toma de decisiones por la gerencia, es decir, una vez realizado un análisis previo de la situación de la empresa, cuán importante es aplicar o no aplicar la investigación de mercados.   Palabras clave: Planificación, análisis, empresas, consumidores, competencia, estrategias.   ABSTRACT Market research is beneficial in various situations; however, the decision to make it is not automatic, this decision must be based on previous considerations of many aspects, among which we can mention, the comparison between costs and benefits, the resources available to carry it out and to put it into practice, as well as the attitude of management towards its realization. Therefore, it should be done when the value of the information generated, exceeds the costs of carrying it out. The more important the decision faced by management and the greater the uncertainty or the risk involved, the greater the value of the information obtained. Market research is usually carried out by commercial companies that are independent organizations (external suppliers) or departments within corporations (internal suppliers). Motivation in profits sometimes causes researchers or clients to put at risk the objectivity or professionalism associated with the process. As researchers, this arouses our interest and through surveys carried out in several companies within the province of Manabí, it aims to publicize the impact that generates the market research in decision making by the management, namely, once a previous analysis of the situation of the company, how important it is to apply or not to apply market research.   Key words: Planning, analysis, companies, consumers, competition, strategies.

The Impact

Using a proprietary dataset of meta-orders and prediction signals, and assuming a quasi-linear impact model, we deconvolve market impact from past correlated trades and a predictable return component to elicit the temporal dependence of the market impact of a single daily meta-order, over a 10-day horizon in various equity markets. We find that the impact of single meta-orders is to a first approximation universal and slowly decays to zero (or to a small value), possibly as a power-law. We show that autocorrelated order-flows and trade information contents fully accounts for the apparent plateau observed in the raw data. We discuss the possible bias introduced by the quasi-linear assumption.
