Identidades cristãs e práxis judaizante na Ásia Menor romana do século II d.C.: Um exame das epístolas de Inácio de Antioquia
Authors: Selvatici Monica
Published: October 2020

Este artigo se insere no quadro maior dos estudos sobre as identidades no cristianismo antigo. A questão central é compreender de que formas as práticas populares se relacionam com o desenvolvimento e a manifestação das identidades cristãs (ênfase no plural). Como práticas populares elegemos as práticas de judaização, entre os não judeus adeptos da fé em Cristo, existentes no contexto das comunidades cristãs. A judaização é assim compreendida porque foge à instrução/controle das autoridades e da elite intelectual cristã. O recorte espaço-temporal do presente estudo são as comunidades cristãs da província da Ásia Proconsular, no território imperial romano, no século II d.C. O conceito de etnicidade é empregado no exame das cartas do bispo Inácio de Antioquia a comunidades cristãs da Ásia Menor de forma a iluminar possíveis motivações para uma manutenção da judaização entre não judeus crentes em Jesus em detrimento da forte recomendação de seu abandono pelas autoridades cristãs.
Repressão além das fronteiras: O CIEx e a espionagem brasileira em Portugal (1974-1979)
Authors: Trevisan Samways Daniel
Published: October 2020

O presente artigo busca analisar o estabelecimento de uma comunidade de informações no exterior, com destaque para o Centro de Informações do Exterior (CIEx) em Portugal, após a Revolução dos Cravos, em abril de 1974. O CIEX estava vinculado ao Ministério das Relações Exteriores e tinha como objetivo repassar informações sobre a atividade de brasileiros exilados ou banidos residentes no exterior. Com o fim da ditadura em Portugal, muitos brasileiros que residiam em outras localidades migraram para aquele país. Tal movimentação preocupou as autoridades brasileiras e instalaram uma unidade do CIEx na embaixada em Lisboa.

Authors: Lima-Pereira Rosuel
Published: October 2020

As regiões ultraperiféricas, RUP, são fronteiras externas da União europeia, UE. Essas fronteiras se situam na região do Caribe, no Oceano Atlântico e no Oceano Índico. Este estudo propõe abordar o lugar da Guiana como região ultraperiférica francesa sob três aspectos. Do ponto de vista jurídico, quais são os tratados, convenções, protocolos adotados pela União europeia, e por conseguinte pela França, em que a Guiana como Região ultraperiférica está incluída. Sob o aspecto econômico e da segurança nacional, quais são as relações de vizinhança entre a Guiana, o Brasil e o Suriname. Finalmente, que tipo de integração a Guiana pode almejar no Platô das Guianas dado seu passado histórico e sua localização geopolítica. Em resumo, nosso estudo propõe analisar os desafios que a Guiana tem de enfrentar em um mundo globalizado e em mutação social em pleno século XXI.
Le Dichiarazioni anticipate di trattamento del Comitato Nazionale per la Bioetica: l’ispirazione alla Convenzione sui diritti dell’uomo e la biomedicina

L’Autore riporta le successive formulazioni che, in seno al Comitato di bioetica del Consiglio d’Europa, ha subito il testo dell’art. 9 della Convenzione sui diritti dell’uomo e la biomedicina (cosiddetta Convenzione di Oviedo, 1997), che tratta delle indicazioni che la persona può esprimere, in forma di desideri, in merito ai trattamenti sanitari applicabili in condizioni vitali in cui può essere impossibile esprimere consenso o dissenso.

Il documento del comitato Nazionale di Bioetica, dal titolo Dichiarazioni anticipate di trattamento, è conforme alle indicazioni del Consiglio d’Europa.
La presa in carico del paziente con sclerosi laterale amiotrofica: questioni etiche nelle varie fasi della malattia
Authors: Pasetti Carlo , Zanini Giovanna
Published: October 2020

Molti sono stati i cambiamenti che si sono verificati in questi ultimi anni nella prassi clinica e nella presa in carico del paziente con sclerosi laterale amiotrofica, nonostante la perdurante assenza di terapie farmacologiche efficaci.

Tali cambiamenti possono essere così riassunti: a) sul piano clinico: l’istituzione di unità interdisciplinari di trattamento alla SLA; la possibilità di impiego di nuove procedure terapeutiche in grado non di modificare la prognosi della malattia ma di prolungarne la sopravvivenza; una sempre maggiore attenzione per la riabilitazione e le malattie croniche progressive; b) sul piano etico: il progressivo affermarsi del principio di autonomia; l’evoluzione di nuovi modelli di relazione medico-paziente.

Questi fattori hanno comportato per gli operatori coinvolti nella presa in carico la irrinunciabile necessità di confrontarsi con nuove questioni etiche, solo pochi anni or sono ritenute del tutto impensabili: 1. la comunicazione della diagnosi e della prognosi; 2. i processi decisionali nelle fasi più avanzate della malattia; 3. l’accompagnamento alla morte e al morente.

Vengono discusse in dettaglio le singoli questioni etiche, arrivando alle seguenti considerazioni conclusive:

1. in tutti i punti nodali della presa in carico del paziente con SLA una corretta informazione e una buona capacità di comunicazione dei terapeuti sono considerati elementi chiave per una gestione clinica che eviti nel paziente rischi di comportamenti autolesivi o di fughe nella medicina alternativa e nel medico rischi di disimpegno terapeutico, angoscia decisionale, burn out;

2. è indispensabile fare evolvere nuovi modelli di relazione medico-paziente, diversi da quelli di tipo paternalistico ma anche da quelli di tipo contrattualistico o utilitaristico, ritenuti più adeguati in questo contesto, come il modello dell’alleanza terapeutica;

3. il rispetto del principio di autonomia e degli strumenti che ne derivano (consenso informato e direttive anticipate in particolare) vengono ritenuti certo un punto forte, ma non l’unico télos etico dell’azione, che deve comunque sempre tendere ad ispirarsi anche, e soprattutto, al principio di beneficenza;

4. un accompagnamento farmaco-protetto alla morte e al morente, calato in un’attenta presenza e in un elevato livello relazionale, secondo un’etica delle virtù che valorizzi le buone intenzioni, può configurarsi come una terza via tra i due opposti errori etici costituiti dall’eutanasia e dall’accanimento terapeutico, terza via che consente di superare annose diatribe tra differenti orientamenti e appare più in linea con paradigmi universalmente accettati e accettabili.
L’impotenza generandi e coeundi nell’uomo e nella donna: humano modo e verum semen
Authors: Picardi Roberto
Published: October 2020

Nel presente articolo viene affrontato il tema dell’impotenza secondo tre prospettive: giuridico-canonica, giuridico-civile, medica.

Per il Diritto Canonico, l’impotenza a compiere la copula (impotentia coeundi), a differenza della sterilità, costituisce un impedimento dirimente e rende nullo il matrimonio, ed è così un ostacolo alla validità del matrimonio. Tale impotenza può essere di due tipi: organica o funzionale. Essa deve essere inoltre antecedenti il contratto matrimoniale e perpetue.

Nel Diritto Civile, l’impotenza, come disagio o anomalia o malattia, può sollevare numerosi problemi, tra questi è prevalente la richiesta d’accertamento e di disconoscimento di paternità.

Per quanto riguarda, infine, il momento medico, esso viene affrontato nell’articolo in funzione degli aspetti utili al Diritto canonico. In questo senso, l’Autore specifica la differenza tra sterilità e impotenza e chiarisce il significato di alcuni termini che spesso vengono utilizzati per descrivere situazioni relative alla procreazione nella coppia.
Personalismo e personalismi. Storia e significati
Authors: Galeazzi Giancarlo
Published: October 2020

Ripercorrendo la storia dell’idea di persona e delle filosofie che l’hanno posta al centro della loro riflessione, l’Autore mostra che il personalismo è un concetto al plurale sia dal punto di vista diacronico che da quello sincronico. In particolare evidenzia come questa caratterizzazione pluralistica sia evidente nel nostro tempo, quando la persona è centrale non solo in filosofie di ispirazione religiosa, ma anche in alcune a connotazione laica, nonché in alcune scienze psicologiche e sociali.

Tuttavia, secondo l’Autore, le diverse forme di personalismo possono essere ricondotte a due orientamenti principali: uno di carattere umanistico (ontologico o etico) e l’altro di carattere naturalistico (funzionalistico o analitico). Una tale distinzione si rivela efficace anche nel campo della bioetica in sostituzione di altre, che si sono rivelate discutibili, come quelle che contrappongono le impostazioni laica e religiosa, della qualità e della sacralità della vita, della disponibilità e della non disponibilità della vita.

Di fronte al diversificato uso del termine persona, l’Autore, pur riconoscendo che ciò ha determinato una certa equivocità, sostiene l’opportunità non di abbandonarlo, bensì di conservarlo: con l’obbligo, però, di qualificare chiaramente le diverse impostazioni, in modo da favorire sia la presa di coscienza dell’attuale conflitto di visioni, sia l’utilità di un confronto tra queste teorie rivali. Solo puntualizzando quanto le accomuna e quanto le differenzia sarà possibile mettere in dialogo i diversi orientamenti, nella consapevolezza che sul tema della persona va cercata la risposta all’interrogazione antropologica, che, dopo l’antropocentrismo moderno e l’antiumanesimo postmoderno, si è resa impellente dal punto di vista teoretico ed etico.
Bioetica e teologia: quale legame?
Authors: May William E.
Published: October 2020

L’Autore intende mettere a tema nel suo contributo il fondamentale tema del rapporto tra la bioetica - che si interessa in particolare di determinare il carattere morale degli atti umani riguardanti la generazione, lo sviluppo e la cura della vita e della salute della persona umana - e la teologia, ossia lo studio disciplinato di Dio e di tutti gli altri esseri nella loro relazione con Dio. L’approccio alla questione muove dal riconoscimento della crucialità del tema del significato della persona umana.

Ad una posizione solistica di stampo teologico e cattolica, la bioetica contemporanea oppone spesso una concezione dualistica, che ha nell’idea del corpo come strumento, piuttosto che come bene intrinseco della persona, il suo punto cruciale. l’Autore propone una critica di quest’ultima impostazione.

La seconda parte dell’articolo è dedicata alla moralità degli atti umani, tema ancora una volta sviluppato a partire dal confronto tra la posizione della teologia cattolica e quella di gran parte della bioetica contemporanea, mal disposta verso gli assoluti morali e gli atti intrinsecamente cattivi, e teorizzatrice di un consequenzialismo etico di chiaro stampo individualistico. Ed è proprio il rischio dell’arbitrarietà ad essere oggetto di critica di una simile concezione, incapace di aprirsi al reale significato della libertà umana.
La questione del metodo nella prospettiva della bioetica di stampo personalista
Authors: Pessina Adriano
Published: October 2020

L’Autore affronta la questione del metodo nella prospettiva personalista. Dopo aver chiarito che non esiste un metodo specifico della bioetica, se non nel senso che la bioetica non fa altro che assumere il metodo di indagine che è specifico della riflessione etica dalla quale dipende, l’Autore sottolinea che l’originalità della bioetica rispetto all’etica sta nell’insieme dei contenuti che essa affronta, ossia azioni e processi mediati dalla conoscenza scientifica e dalla prassi tecnologica.

In particolare, viene proposta una riflessione su come è articolato il metodo triangolare proposto da Elio Sgreccia nel suo noto Manuale di Bioetica. Questo metodo si distingue dal proceduralismo di altre prospettive, sia per la sua connotazione contenutistica, che ha il suo perno in una concezione sostanzialistica della persona umana, sia per la sua struttura critica o dialettica. Nella connessione tra il dato medico-scientifico, il dato antropologico e il momento etico emerge il significato analogo della verità, concetto non confinato soltanto nel campo delle scienze sperimentali ma efficace anche sul piano etico.

In tal senso, la bioetica emerge come una disciplina che si costituisce attraverso un percorso (il itriangolo) che ha il suo esito laddove il giudizio di coscienza è formulato in base alle verità acquisite ed integrate, in base ai diversi beni messi in gioco. Il momento prescrittivo, quello decisivo dell’indagine bioetica, non è assimilabile ad una pura deduzione dai principi morali ma si costituisce all’interno di un complesso itinerario teorico che tiene conto dei diversi approcci alla realtà.
La dimensione socio-culturale della “procreazione medicalmente assistita”
Authors: Belardinelli Sergio
Published: October 2020

Prendendo lo spunto dalla recente legge italiana sulla “procreazione medicalmente assistita” recentemente approvata dal Parlamento italiano, l’autore muove una serie di considerazioni che possono essere sintetizzate in due punti fondamentali.

Anzitutto l’affermazione della dimensione sociale della procreazione, cioè il riconoscimento della necessità di riscoprire nella procreazione, più che una faccenda da relegare alla sfera dell’intimo, un forte significato relazionale (rapporto genitori-figli; rapporto famiglia-società).

Il secondo punto argomentato dall’autore è l’idea per cui la salvaguardia delle condizioni naturali della procreazione riveste per l’umana libertà un’importanza decisiva.
Nephrocalcinosis in genetically proved dopa-responsive dystonia due to sepiapterin reductase deficiency in a Libyan Girl
Authors: Etarhuni Samira , Zeglam Adel , Elbouaishi Awatef , Sharfddin Abdulbast
Published: October 2020

Dopa-responsive dystonia (DRD) encompasses clinically and genetically heterogeneous disorders that typically manifest as limb-onset, diurnally fluctuating dystonia and exhibit a robust and sustained response levodopa treatment. GCH1 gene mutations are the most frequent cause of DRD. Mutations in the TH or SPR gene less often cause this condition. The index case is a 12-year-old young girl presented to the pediatric neurology clinic at the age of 8 years with tiptoes walking and deterioration of her gait. She is the product of first-degree consanguineous marriage with insignificant history. The index case has two sisters, one of whom suffers from learning difficulties, epilepsy, and bilateral nephrocalcinosis. Her two uncles had severe axonal polyneuropathy and died in their forties of unknown cause. Her magnetic resonance imaging of the brain demonstrated agenesis of the corpus callosum. Renal ultrasound studies showed bilateral nephrocalcinosis. Genetic DNA evaluation (whole-exome sequencing) identified the heterozygous variant c.207C>G,p. (Asp69Glu) in the SPR gene (OMIM: 182125), which leads to an amino acid exchange. Nine out of ten bioinformatic in silica programs predict a pathogenic effect for this variant. Treatment with levodopa\ benserazide 4:1 (Madopar) has not made any changes to the girl's condition.

Authors: Bongsebandhu-phubhakdi Chansuda , Wacharasindhu Suttipong
Published: October 2020

Aims: To determine the prevalence and severity of endocrine and metabolic derangements in childhood-onset alL survivors from Thailand and to describe the associated risk factors. Settings and Design: Paediatric department in medical school hospital, cross-sectional study. Methods: Insulin Tolerance Test (ITT), IGF-I and IGFBP-3 levels, Thyroid and gonadal function, serum sodium and metabolic profiles were investigated in 30 childhood onset alL survivors. (16 males, 14 females, mean age: 14.66 ± 7.16 years). Results: Endocrine abnormalities were displayed in 73.33 % of patients, 46.7% had two or more abnormalities. Grade3 of severity were present in 16.67%. Growth hormone deficiency (GHD) was detected in 10 patients (33%). Early onset of ALL was the potential risk factor of GHD. Adult height was more deteriorated in the female group. Twenty percent of patients were found with subnormal cortisol responses. Gonadal failure was evidenced in one case that experienced testicular irradiation. No diabetes insipidus was detected. Among 6 obese patients, 2 patients developed metabolic syndrome. Moreover, one patient was diagnosed with insulin-depleted diabetes mellitus. Conclusion: Our results highlighted various endocrine and metabolic sequelae occurring in childhood-onset alL survivors after completion of their therapy. The prevalence of GHD was higher than the one previously described in Japan population. Subclinical hormonal abnormalities may affect health outcomes. Biochemical and hormonal abnormalities should be carefully monitored for immediate treatment.

Context: We describe the treatment of cancer patients carried out in a Government of India-designated, dedicated coronavirus disease (COVID) hospital (DCH) in a COVID hotspot in India. Aims: The aim was to study the change and delay in the management of cancer patients during the pandemic and its complications. Settings and Design: This was an observational cohort study conducted at a tertiary care center, which was also a DCH. Subjects and Methods: Cancer patients receiving cancer surgery, chemotherapy, and radiotherapy in our DCH, during the lockdown, were studied. Results: A total of 864 patients received treatment for cancer in our hospital during the period of March 20, 2020 – May 31, 2020. There were no COVID-related complications. The treatment of 109/864 patients (12.61%) was delayed due to the pandemic and lockdown situation and the treatment plan was changed for 84/864 (9.72%) patients. There were 21 deaths in these 864 patients (2.43%), but only two deaths were COVID related. Symptomatic patients were tested for COVID, and 3/864 patients (0.34%) were detected to be COVID positive.Conclusions: We successfully delivered cancer treatment to patients in our DCH. The percentage of adverse effects, symptomatic COVID infection, and related mortality has been very low in our study. Cancer care can be continued with due diligence even during this pandemic.

Authors: Rathore Vatsna , Taluja Ankit , Arora Puneet Rana , Bagai Poonam , Kapoor Gauri , Seth Rachna , Arora Ramandeep Singh
Published: October 2020

Background: Continuum of care is an important concern for childhood cancer survivors. Studies from high-income countries indicate a significant development in services to these survivors. Similar information is unavailable from India. Methods: An online survey form was developed and sent to 86 centers. Data were collected over a 6-month period in 2017. Results: Fifty nine centers responded (44.1% private sector, 33.9% public, and 22.0% charitable trust). The services are mainly provided (91%) within routine oncology clinics. There is no upper age limit (61%) or time period limit (63%) for follow-up at most of the centers. The major barriers for follow-up are distance, lack of knowledge, lack of adequate facilities, and patient priority for follow-up. Conclusion: This survey provides baseline information on current service provided to childhood cancer survivors in India. There is a need to inform, educate, and sensitize the survivor and their family as well as improving services.
Growth of Sobolev norms for abstract linear Schrödinger equations

Published: October 2020

We prove an abstract theorem giving a

\langle t\rangle^\epsilon

bound (for all

\epsilon > 0

) on the growth of the Sobolev norms in linear Schrödinger equations of the form

\mathrm i \dot \psi = H_0 \psi + V(t)\psi

as

t \to \infty

. The abstract theorem is applied to several cases, including the cases where (i)

H_0

is the Laplace operator on a Zoll manifold and

V(t)

a pseudodifferential operator of order smaller than 2; (ii)

H_0

is the (resonant or nonresonant) Harmonic oscillator in

mathbb \R^d

and

V(t)

a pseudodifferential operator of order smaller than that of

H_0

depending in a quasiperiodic way on time. The proof is obtained by first conjugating the system to some normal form in which the perturbation is a smoothing operator and then applying the results of [MR17].

Green and facile synthesis of cerium doped Ni3Fe electrocatalyst for efficient oxygen evolution reaction
Authors: Kanwal F. , Batool A. , Akbar R. , Asim S. , Saleem M.
Published: October 2020

Electrochemical water splitting is the most promising pathway to produce high-purity hydrogen to alleviate global energy crisis. This reaction demands inexpensive, efficient and robust electrocatalyst for its commercial use. Herein, we demonstrate an effective, facile and scalable method for the synthesis of cerium doped Ni3Fe nanostructures as an electrocatalyst for oxygen evolution reaction (OER) by following simple chemical bath deposition route. The different molar ratios (3, 6 and 12 mM) of cerium in the chemical bath were used to study its effect on the structural and the electrochemical properties of the Ni3Fe nanostructured films. Doping of cerium contents induced variations in the morphology of deposited Ni3Fe nanostructures. The optimized electrocatalyst Ni3Fe/Ce-6 yielded high surface area catalyst nanosheets uniformly deposited on three-dimensional conductive scaffold to ensure increase in the exposure of doped Ni3Fe catalytic sites with high electrical conductivity. As a result, this earth-abundant electrocatalyst affords high OER performance with a small overpotential of 310 mV versus reversible hydrogen electrode (RHE) at 10 mA cm-2 and retains good stability up to ~ 10 h in alkaline electrolyte. This scalable strategy has great potential in future advancement of efficient and low-cost electrocatalysts for their large-scale application in energy conversion systems.

Spectroscopic and thermal studies of cyano bridged hetero-metallic polymeric complexes derived from ligands containing N and S donor atoms
Authors: Karaağaç D.
Published: October 2020

The new cyano bridged hetero-metallic polymeric complexes [Cu(dmtu)2Pd(CN)4]∙H2O and [Cu(H2O)2(detu)2Pd(CN)4]∙2H2O (dmtu = N,N'-dimethylthiourea, detu = N,N'-diethylthiourea; abbreviated henceforth as Cu–Pd–dmtu and Cu–Pd–detu) have been synthesized for the first time in powder form and their structures have been determined by vibrational (FT-IR and Raman) spectroscopy, thermal and elemental analysis techniques. Using vibration spectra of the complexes, it has been discussed whether the ligands are bound to metal atoms or not. According to the results obtained from the spectra of the complexes, the palladium atom is four coordinated with four cyano groups in a square planar geometry whereas the copper(II) atom of Cu–Pd–detu is six coordinated with two bridging cyano groups, two aqua and two detu ligands (four bridging cyano groups and two dmtu ligands for Cu–Pd–dmtu) in a distorted octahedral geometry. In addition, complex Cu–Pd–dmtu is similar to structure of the Hofmann type complexes and its structure consists of polymeric layers of |Cu–Pd(CN)4|∞ with the dmtu ligand bounded to the copper(II) atom. Thermal stabilities and decomposition products of the complexes were also investigated in the range of 30–1000 ºC in the static air atmosphere using TG, DTG and DTA techniques.

Authors: Armoogum V. , Boodhoo K.
Published: October 2020

Five HPLC methods were employed for the quantitative analysis of three natural sugars namely fructose, glucose and sucrose in soft drinks. HPLC-refractive index detector (RID)-AMINO proved to be the most suitable HPLC method to carry out the latter task. For the optimum separation and response of the natural sugars the best conditions employed were column oven temperature 30 oC, flow rate 0.1 mL/min, mobile phase ratio acetonitrile:water 75:25 and they were determined by studying all possible interactions among these three parameters. Full validation of HPLC-RID-AMINO was performed in terms of system suitability test, precision check, accuracy check and robustness.

The title compound, N-(2-pyridylmethyl)-L-alanine) zinc(II), [Zn(C10H11N3O2S)], a coordination polymer derived from the mixed ligands, N-(2-pyridylmethyl)-L-alanine (HL1) and ammonium thiocyanide (L2) has been synthesized and characterized by IR spectroscopy, 1H-NMR, elemental analysis, thermogravimetric analysis and single crystal x-ray structure determination.The single crystal X-ray structure analysis of the title compoundreveals a molecular polymeric compound that crystallizes in the orthorhombic crystal system and P2(1)2(1)2(1) space group. The ligand acts as a bridge between adjacent zinc(II) centres, each of which adopts a five-coordinate geometry.  Zinc bonds to two N atoms and one O atom of HL1, one N atom of L2 and one O atom of another HL1 ligand. This is confirmed by IR spectroscopy. Thermogravimetric analysis shows a one-step decomposition of the complex to leave a zinc sulfide residue.

Value chain analysis of mangrove forests in central Mozambique: Uses, stakeholders and income
Authors: Machava-António Vilma , Bandeira Salomão O. , Macamo Célia C. , Mahanzule Rosalina
Published: October 2020

This study aims at documenting the value chain derived from mangrove forests in selected sites in central Mozambique (Zambezi Delta, Nhangau and Chiveve River), through the identification of the services delivered by mangrove forests and assessment of stakeholder’s engagement within the value chain. Furthermore, this work evaluates the income pathways as well as the current and potential benefits of different stakeholders and the socio-economic sustainability of mangroves in the three regions. Zambezi Delta is one of largest mangrove swamps in Africa and Chiveve is located in Beira City, impacted by Cyclone Idai in 2019. The main benefits obtained by the communities both in the Zambezi Delta and Nhangau were derived from commercially important wood extraction and honey production for domestic use. Within the Zambezi Delta, profit for small mangrove poles accrued at the wholesale level (82.6%), while that for large poles accrued to harvesters (125.0%), after a small initial direct investment. At Nhangau, small poles fetched profits of 17%, medium poles 11.5%, and large poles 24%; for charcoal, the greatest portion of profits went to retailers at 50%. Men were mostly involved in mangrove wood harvesting for commercial purposes, while women collected firewood mainly for domestic use. At the Chiveve, the community benefited predominantly from non-extractable services such as flooding control, water purification, nursery grounds for fisheries and aesthetic beauty. It is suggested that Mozambique mangrove forests are valued at USD 2 400 per hectare per year. This monetary accounting can be used to inform decision making on mangrove management and to improve the performance of the value chain and the wellbeing of local communities.
Characterisation of artisanal catches in selected fishing areas of the Lower Tana Delta and Malindi-Ungwana Bay, Kenya
Authors: Dzoga Mumini , Simatele Danny , Munga Cosmas
Published: October 2020

Shore-based assessment of fisheries resources in Ngomeni, Kipini and Ozi fishing areas of Malindi-Ungwana Bay and the Lower Tana Delta on the north coast of Kenya was conducted from January to December 2017 to establish catch composition, species richness, and fishing effort (catch-rate, number and types of fishing gears and crafts) in the marine, estuarine and riverine habitats. Distinct catch composition (R = 0.27, P < 0.05) was observed across the three habitats. Catch composition differed significantly spatially and seasonally across the three fishing areas, and between the north east (NE) and south east (SE) monsoon seasons (R = 0.332, P < 0.05). The wolf herring, Chirocentrus dorab, was the most abundant fish species in Ngomeni, centrally located in Malindi-Ungwana Bay, while the catfishes, Arius africanus and Clarias gariepinus, were the most abundant species in Kipini and Ozi, respectively. Gillnets operated from dhows (mashua) and fibre-reinforced plastic (FRP) boats in Ngomeni (marine), and canoes using-basket traps in Ozi (riverine), landed significantly larger Spanish mackerel, Scomberomorus commerson, and sea catfish, Arius africanus (Kruskal Wallis test: Df = 2; F = 197.141; p < 0.001; Df = 2, F = 490, p < 0.001), respectively. Species diversity by area in combination with habitat and type of fishing craft showed higher diversity for Ngomeni in the marine habitat with mashua fishing crafts than in Kipini. Significantly different catch rates (Df = 2, F = 10.43, p<0.001; Df = 1, F = 5.897, p < 0.021) were observed in the three (3) fishing areas and during the NE monsoon and the SE monsoon, respectively. Canoes were the most common fishing craft used, especially in Ngomeni, accounting for 37.1%, and 97.5% in Ozi, while mashua crafts accounted for 44.5% of the total fishing craft in Kipini. Monofilament nets were most common in Ngomeni (34.0%) while basket traps dominated the Ozi site at 63.6%. The Kipini area was dominated by handlines (28.8%). It is therefore evident that the three (3) fishing areas of the Malindi-Ungwana Bay and Lower Tana Delta showed significant differences in catch composition and size of fish caught, attributed partly to the variation in habitat types and fishing methods between the sites. Overall, the Ngomeni area was characterized by more advanced fishing craft with the majority powered by engines, including mashua and FRP boats, compared to Kipini and Ozi fishing areas where canoes were dominant.

Published: October 2020

One hallmark of Polish unemployment regulations introduced gradually from the early 1990s is that apart from protective actions i.e. unemployment benefits they make provision for instruments supporting professional activation of the unemployed. Throughout time the regulations concerning this matter evolved and new forms of support for the unemployed were introduced, taking into account the needs of the changing labour market. The necessity of tackling the challenges of the labour market in post-industrial economy, especially in terms of increasing employment flexibility, led to development and rise in significance of atypical employment forms. Such solutions are also used in encouraging professional activation of the unemployed. This study comprises analysis of three atypical employment practises: part-time employment, telework and temporary employment which apply to the unemployed in accordance with the rules of the Act of 20 April 2004 on employment promotion and on labour market institutions, regulations about job market instruments.

In spite of its obligation-based nature, the contractual employment relationship of university teachers still has some properties that make it similar to the structure of a public law service relationship. Here, the specificity of the employment of university teachers is determined by the elements of content of their employment relationship that are closely linked to the realisation of the government’s duties related to science and higher education. The different employment status of university teachers is in fact a heterogeneous solution, where the obligation-based nature of the employment relationship is complemented with elements that are characteristic for public law service relationships.

The Islamic economy is not really a new discourse on whether its roots have evolved since the early days of Islamic civilization. Discussions on economic issues from an Islamic perspective started early and have flourished in the Islamic golden age since. However, economic issues are mainly solved by different branches and schools of economics. This raises a wide variety of methodological issues and several problems have been central to methodological reflection concerning economics. However, not much research attempts have been done to survey the origin of Islamic economic thought and portray its evolution towards becoming a discipline in contemporary times with its own body of knowledge and methodology. Therefore, this study is likely to fill this gap and chart the future direction of the discipline will also be highlighted with some evaluations of the current state of the arts.

This systematic review explores the international postgraduate education and training programmes designed to provide or develop knowledge or skills focused on enabling pharmacists to work in a general practice setting. Four thousand, eight hundred and seventy-one (4,871) articles were identified from database searches of SCOPUS, EMBASE, Medline, CINAHL, IPA, Web of Science and ERIC. After removal of duplicates and article screening, seven articles were included. Educational content, setting, contact time and methods of assessment varied across all studies. There is paucity of published literature relating to the development and evaluation of education programmes directed at pharmacists entering into general practice. A combination of work and classroom-based education provided by general practitioners and pharmacists already working in primary care is deemed most beneficial coupled with systematic debriefing sessions at the completion of training courses. The findings suggest future training should focus on specific disease states.

Objective: The goal of this study was to determine what students need to know about biochemistry in order to practice pharmacy.
Methods: With reference to a list of learning objectives, educators interviewed students during their advanced clinical rotations, asking if they had used each item in practice. Each item was then rated according to the number and strength of affirmative responses. The ratings were used to identify the elements of biochemistry most strongly recognised as relevant to clinical practice.
Results: All of the learning objectives received affirmative responses, indicating that each was recalled or used by some respondent(s). The most highly rated objectives indicate aspects of biochemistry most closely related to clinical practice.
Conclusion: The results provide guidance to educators for designing biochemistry courses, highlighting recognisable connections between biochemistry and clinical practice, and areas where relevance may need to be made clearer or re-evaluated.
