Published: April 2021

Introduction: Hypertensive disorders of pregnancy is one of the major complications of pregnancy. It forms the fatal triad along with the
haemorrhage and infection that contributes greatly to fetal and maternal morbidity and mortality.Of the various parameters used, platelet count is
the most simple and cost effective method for prediction of PIH(Pregnancy induced hypertension).This study soughts the importance of platelet
count as the most consistent and reliable method in early detection of PIH cases.
Materials and methods: A prospective study was conducted on 164 cases and 70 controls over a period of 2 years. The bleeding time, clotting
time, hemoglobin estimation and platelet count were performed.The patients were classied into mild preeclamptic, severe preeclamptic and
eclamptic based on the clinical and haematological parameters.
Observations: The platelet count in severe preeclampsia and eclampsia was signicantly lower than in mild pre eclampsia and controls.
Thrombocytopenia was seen in total 35 cases of severe pre-eclampsia and eclampsia combined,out of which 30 (85.7%) had poor maternal
outcome and 34 (97.1%) poor fetal outcome.
Conclusion:The frequency of thrombocytopenia is found to be directly related with the severity of disease. So routine test like platelet count can be
used as a simple and cost effective tool to monitor the progression of preeclampsia and and plan preemptive management strategies that has been
proven to have a crucial role in reducing the morbidity and mortality of both mother and fetus

Published: April 2021

The exponential growth of traffic in mobile networks is leading to an increased pressure on the infrastructure of mobile networks and in particular on their backhaul networks. It is more critical than ever to carefully plan backhaul networks. In this paper, we formulate and solve the problem of hierarchical wireless backhaul network design. In our problem, we cover different requirements, namely: topology simplicity, network resiliency and link reliability. We formulate the problem as an Integer Linear Programming (ILP) problem, allowing us to solve the problem to optimality. Furthermore, we provide a graph theory based algorithm that allows to solve the problem overlarge scale. The proposed algorithm exploits the properties of the graph representing the network. The results of our evaluations in various network scenarios demonstrate the efficiency of our ILP formulation and the provided algorithm in keeping the backhaul network simple, resilient and reliable. Using a practical channel propagation model and different node densities that are representative of small-scale and large-scale urban environments, our results also show that even with high resiliency requirements, the network traffic can be backhauled with only5−10%of the nodes for the considered densities. Our results also demonstrate that our algorithm leads to near-optimal solutions in different scenarios.

Some physicochemical properties of five brands of sachet and five brands of bottled water sold/produced in Abraka; Ethiope East Local Government Area of Delta State was investigated. Amounts of heavy in the water samples were also determined. The results were compared with World Health Organization (WHO) standards and Nigerian Standard for Drinking Water Quality (NSDWQ) respectively. Seventy percent of the samples had pH levels below the minimum level of 6.50 recommended by WHO and NSDWQ, suggesting that the water samples are acidic. The slight acidity of the water samples may not be unconnected to impurities from poor treatment techniques. Results for other physicochemical parameters: EC (78.60 ± 34.06 µs/cm), TDS (42.80 ± 18.46 mg/L), Temperature (30.02 ± 0.46 OC), Cl- (16.88 ± 7.01 mg/L), NO3- (0.12 ± 0.05 mg/L), NO2- (<0.001 mg/L), TH(10.60 ± 7.09 mg/L), Cu(0.05 ± 0.00 mg/L), Fe(0.34 ± 0.19 mg/L), Zn(0.11 ± 0.02 mg/L) and Mn (0.03 ± 0.00 mg/L) for sachet water samples; EC (99.60 ± 76.18 µs/cm), TDS (54.20 ± 41.84 mg/L), Temperature (29.96 ± 0.21 OC), Cl- (20.85 ± 17.44 mg/L), NO3- (0.12 ± 0.03 mg/L), NO2- (0.01 ± 0.01 mg/L), TH(15.00 ± 16.36 mg/L), Cu(0.04 ± 0.01 mg/L), Fe(0.20 ± 0.15 mg/L), Zn(0.11 ± 0.03 mg/L) and Mn (0.09 ± 0.01 mg/L) for bottled water samples; were within permissible limits, indicating that the water samples are good enough for human consumption.
Design Mix Formulation and Optimization of Metakaolin Based Alkali Activated Geopolymer Concrete with the Taguchi Method
Authors: Okovido J.O. , Yahya I.A.
Published: April 2021

Concrete mix formulation is the science of deciding relative proportions of ingredients of concrete, to achieve desired properties in the most economical way. Formulation of concrete mix requires adequate knowledge of the properties of its constituents. Aluminosilicate materials have recently found applications in construction industry due to their unique and flexible properties. The metakaolin used for this study was the locally sourced kaolin calcined at 750oC. The alkali activating reagents include a fixed concentration of sodium silicate solution and sodium hydroxide solutions of three different concentrations. Strength development of metakaolin – based geopolymer concrete is quite different from that of ordinary Portland cement concrete due to differences in their constituents, hence, the need for special formulation, most especially when high strength is required. Taguchi method was adopted in this study to formulate mix proportion for high compressive strength of geopolymer concrete at ambient curing condition. Four parameters were selected that are more likely to influence the compressive strength of metakaolin – based geopolymer concrete, these include aggregate content, alkali – binder ratio, alkali reagent ratio and alkali reagent concentration. The effect of these parameters on the density, workability and compressive strength at 3, 7 and 28 days are determined. The result showed that an optimum mix obtained from a formulation formula (2.75SiO2 * Al2O3 * 0.55Na2O * 6.8H2O) produced a compressive strength of 62MPa at 28 days of open air curing. It was revealed that the molar concentration of the alkali reagent (sodium hydroxide) should be kept within 10M range for an open air curing, the alkali reagents to binder ratio should be kept at 0.7 or less with no addition of water to achieve reasonable workability. Also, it has been observed that the bulk density of metakaolin – based geopolymer concrete that yielded substantial strength fall within 2250kg/m3 and 2350 kg/m3.
The Bimbot: mediating technology for enacting coordination in teamwork collaboration
Authors: Mutis Ivan , Ramachandran Adithya
Published: April 2021

Today, BIM technologies in collaborative practice are widespread among construction project stakeholders. However, embracing either distributed or collocated tasks in collaborative practices is a complex, challenging activity. Each team member (actor) views collaborative design problems from a different ‘lens’, framed by the realities of their disciplines, experiences, and levels of engagement on tasks. The effect is a practice prone to conflict generation and misunderstandings among actors. BIM technologies and teamwork should be configured to adapt to one another in practice dynamically. The configuration should enable the effective performance of distributed and collocated work tasks. The presented study investigates these configurations to reveal constitutive aspects of how work should be executed in practice. The study focuses on adapting technology and teamwork to reveal a more effective way of delivering distributed and collocated work tasks. To explore the research question, two components were developed: a theoretical framework and a technology conceptualization. The framework presents fundamental constitutive elements in the coordination process. It illustrates the key aspects that draw the configurations of technology and teamwork. The technology concept is a design to assist in the execution of the tasks for coordination activities. It addresses the constitutive aspects of coordination for BIM processes in practice. The technology concept, named BIMbot, is a cognitive assistant that informs and advises on activities, engages team members together in a task, and facilitates fundamental actions for shared understandings, physical support, and informed advice. This paper contributes to shedding light on the difficulties for team members to reach a shared understanding of knowledge when they use BIM technologies. It presents the first development of the design of technology that provides actionable information to coordinate activities.

On the Non-Inflationary effects of Long-Term Unemployment Reductions
Authors: Paternesi Meloni Walter , Romaniello Davide , Stirati Antonella
Published: April 2021

The paper critically examines the New Keynesian explanation of hysteresis based on the role of long-term unemployment. We first examine its analytical foundations, according to which rehiring long-term unemployed individuals would not be possible without accelerating inflation. Then we empirically assess its validity along two lines of inquiry. First, we investigate the reversibility of long-term unemployment. Then we focus on episodes of sustained long-term unemployment reductions to check for inflationary effects. Specifically, in a panel of 25 OECD countries (from 1983 to 2016), we verify by means of local projections whether they are associated with inflationary pressures in a subsequent five-year window. Two main results emerge: i) the evolution of the long-term unemployment rate is almost completely synchronous with the dynamics of the total unemployment rate, both during downswings and upswings; ii) we do not find indications of accelerating or persistently higher inflation during and after episodes of strong declines in the long-term unemployment rate, even when they occur in country-years in which the actual unemployment rate was estimated to be below a conventionally estimated Non-Accelerating Inflation Rate of Unemployment (NAIRU). Our results call into question the role of long-term unemployment in causing hysteresis and provide support to policy implications that are at variance with the conventional wisdom that regards the NAIRU as an inflationary barrier.

Published: April 2021

The costs of the organization are the assets of the organization, including material values, labor re-sources, which transfer their value to finished products, work, services. In modern economic conditions of economic activity of an economic entity, the simple assignment of costs to the cost of production has lost its significance. This is due to the fact that it is necessary to satisfy the request of the end consumer through a price offer for the product, as well as the request of the state through the payment of taxes to the treasury. Consequently, management is required to implement measures to manage the costs of an economic entity. This article discusses the question of what methods can be used to implement cost management, and in addition, it presents a basic conceptual model for managing production processes of an economic entity and a model of a production cost management system using the example of the coal industry.

Krisendiagnostik einer kritischen Stadtforschung
Authors: Kip Markus
Published: April 2021

Höhne und Michel (2021) beschreiben Symptome einer „Krise der Städte“, die im Zuge der Coronapandemie deutlicher zum Vorschein kommen. Mit ihren Thesen legen sie nahe, dass es auf ein Ende des Städtischen – as we know it – hinauslaufen könnte. Im Grunde genommen bezeichnen viele der Thesen Entwicklungen, die schon vor der Pandemie zu beobachten waren. Gerne gehe ich auf die Einladung ein, über die Krisendiagnostik einer sich als kritisch verstehenden Stadtforschung zu reflektieren. Anstoß nehme ich daran, dass die Perspektive der Krisendiagnostik im Debattenaufschlag ungeklärt bleibt. Aus wessen Sicht wird hier eine Krise diagnostiziert und mit welchem Zweck? „Kritisch“ im von mir vorgeschlagenen Sinne ist eine Stadtforschung, die sich in der Krise zu verorten und (Ent-)Scheidungen herbeizuführen weiß. Dieser Beitrag argumentiert für eine kritische Stadtforschung als konsequente Fortsetzung des Erbes der Frankfurter Schule. Er baut auf Kernideen aus „What is Critical about Critical Urban Theory?“ von Neil Brenner (2009) auf.

Le projet Lumieau-Stra est un des lauréats de l’appel à projets « Micropolluants et innovation »,
lancé en 2013 par le ministère de la Transition écologique, l’Office français de la biodiversité et les agences
de l’eau, dont l’objectif principal était d’aider les collectivités à agir pour mieux connaître et réduire l’impact
des micropolluants sur les milieux et les ressources aquatiques de leur territoire. Un outil innovant d’aide
à l’identification des sources et à l’élaboration d’un plan d’actions de réduction des émissions de
micropolluants à l’échelle d’un territoire urbain a été développé dans le cadre de ce projet porté par
l’Eurométropole de Strasbourg et réunissant huit partenaires. L’outil développé se base sur une approche
évolutive en deux modules. Dans sa partie « diagnostic », l’outil permet d’identifier les bassins versants et
émetteurs (industries, artisans, particuliers, eaux pluviales) qui contribuent potentiellement aux rejets aux
exutoires du réseau d’assainissement (déversement vers les milieux récepteurs en temps de pluie et
déversoir en tête de station de traitement des eaux usées (STEU)) et en entrée de station d’épuration. Les
actions de réduction à mettre en place peuvent être priorisées sur la base de cette identification. Dans la
partie « plan d’actions », une boîte à outils de solutions de réduction des micropolluants permet d’identifier
celles qui sont adaptées au contexte local. L’outil permet alors de simuler des scénarios de mise en place
d’actions sur le territoire étudié. L’outil permet ainsi d’évaluer l’impact de la mise en place d’un plan
d’actions sur les sources d’émissions de micropolluants, sur les milieux récepteurs et sur l’effluent en
entrée de STEU. Il a été développé puis appliqué au territoire de l’Eurométropole de Strasbourg. L’outil
peut, dans une version adaptée, être utilisé pour accompagner la réalisation des diagnostics vers l’amont
des STEU demandés réglementairement par la note technique du 12 août 2016.

Cold chain processes of horticultural products in tropical countries is very urgent to maintain product quality. In Indonesia, the temperature and humidity are relatively high, so that the deterioration of horticultural products is very fast. Because of the high humidity, this condition can highly possibly use a natural humidifier for a cold room by purging humid ambient air to the refrigerator cabin with the best certain time. Meanwhile, as a tropical country, solar energy has good reliability to be developed. This study aims to determine the performance of the medium temperature refrigerator with a natural humidifier using solar energy as energy source. This research was conducted as an experimental investigation. The rig has been built completely with measurements and instrumentation for precise temperature and humidity control. The results showed that the system reached a quite good coefficient of performance (COP), with the thermodynamically COP of 3.6. However, humidifiers contribute a cooling load which can affect the temperature increase of 1o C - 1.5o C in the cooling system. Further studies will examine the optimization of the refrigerator system with natural humidifiers with low electricity consumption and eco-operating conditions with the best combination of temperature and humidity to keep the product of good quality in a long storage time.

In this paper we establish the existence and uniqueness of a coupled fixed point for operators F : X × X → X satisfying a new type of contractive condition, which is weaker than all the corresponding ones studied in literature so far. We also provide constructive features to our coupled fixed point results by proving that the unique coupled fixed point of F can be approximated by means of two distinct iterative methods: a Picard type iterative method of the form xn+1 = F(xn, xn), n ≥ 0, with x0 ∈ X, as well as a two step iterative method of the form yn+1 = F(yn−1, yn), n ≥ 0, with y0, y1 ∈ X. We also give appropriate error estimates for both iterative methods. Essentially we point out that all coupled fixed point theorems existing in literature, that establish the existence and uniqueness of a coupled fixed point with equal components, could be derived in a much more simpler manner.

Published: April 2021

Assessing the impact of methods of corporate social responsibility management on financial performance is one of the key aspects to implement strategic management into practices. There are contradictory results of this impact’s study in the literature due to the difference in the applied methods of measuring variables, errors in models etc. The available literature is still inconclusive about this aspect, in particular, for the metallurgical industry, which plays a significant role in Ukrainian and world economy. The purpose of the paper is to evaluate the impact of corporate social responsibility on the company financial performance and to determine the financial efficiency of socially responsible initiatives for the metallurgical industry in particular. It proposes methodology for assessing the impact of corporate social responsibility on the corporate financial performance, and it uses data from a socially oriented balanced scorecard. The research methodology includes correlation and regression analysis with panel data techniques based on data from a balanced scorecard for a sample of four dominant market participants in the Ukrainian metallurgy in 2010-2018. Authors assess the level of corporate social responsibility by indicators of four perspectives, such as: internal processes, learning and growth, environmental, and relational perspective that characterizes the level of satisfaction of various stakeholder groups with the company’s activities in the field of corporate social responsibility. The initial data for the analysis have been taken from the financial and non-financial statements and results of expert assessment. The study uses linear and panel regression models with fixed and random effects in order to demonstrate the impact of four independent variables (internal processes, learning and growth, environmental, and relational perspectives) on the financial perspective as a dependent variable. The panel effects made it possible to obtain more accurate model’s parameters compared to simple linear regression model. The empirical finding from the study illustrates a strong and statistically significant relationship between the relational perspective, which is a corporate social responsibility indicator, and the financial perspective in the socially oriented balanced scorecard. This means that the costs of creating and maintaining a positive image of metallurgical companies are fully justified by improving their bottom line. Future research directions compare the effectiveness of statistical methods evaluating the impact of corporate social responsibility on the company financial performance with alternative methods, e.g. data mining techniques, in terms of forecasting accuracy.

An English-Spanish glossary for the study of the artificial pancreas in medical translation
Authors: Jiménez Garro Belen
Published: April 2021

Type 1 diabetes is a malady that affects millions of people around the world. The latest scientific and technological advancements have designed a device that aims at improving patient’s quality of life: the artificial pancreas enables them to control and manage this illness in a more automated and efficient way. Nevertheless, as a consequence of the influence of English worldwide and, in particular, in the field of science, the information available in Spanish is scarce, which also limits the dissemination of knowledge to a wider public. In the field of scientific and technical translation terminological units play a pivotal role, since they concentrate a huge part of the knowledge regarding the subject topic. However, these units are not free from synonyms and univocity is not their characteristic, which may lead to confusion. Therefore, the standardization of terms is essential so as to elaborate an adequate translation that will serve to spread knowledge, as well as to facilitate communication among experts. The present work seeks to develop a glossary of terms in English and Spanish related to the artificial pancreas that could be of great use for diverse profiles: translators, experts, patients, and people interested in the topic.

The exceptional migratory flows in 2015-2016 have entailed several challenges for the Flemish public service interpreting sector, including a mismatch in supply and demand, a shortage of interpreters for lesser-used language varieties, and government budget constraints. In order to meet these challenges head-on, the Flemish Government Integration Agency, responsible for certifying public-service interpreters, has set up a research project designed to determine whether, and under what circumstances, briefly trained volunteer “language assistants” (LAs) could offer a valid additional form of language mediation. First, participants were trained and evaluated when interacting, mainly through role plays, with fellow trainees. Second, their interpreting performances during real-life service provision interactions were video-recorded and assessed. The LAs’ interpreting performances were assessed predominantly as unsatisfactory, with the main risks being linked to low interpreter competence, language proficiency, and deontological awareness. Those findings have been addressed in a follow-up project, by increasing the required CEFR level of Dutch and by changing the content of the training.

Many studies suggest that information about past experience, or episodic memory, is divided into discrete units called “events.” Yet we can often remember experiences that span multiple events. Events that occur in close succession might simply be linked because of their proximity to one another, but we can also build links between events that occur farther apart in time. Intuitively, some kind of organizing principle should enable temporally distant events to become bridged in memory. We tested the hypothesis that episodic memory exhibits a narrative-level organization, enabling temporally distant events to be better remembered if they form a coherent narrative. Furthermore, we tested whether post-encoding memory consolidation is necessary to integrate temporally distant events. In three experiments, participants learned and subsequently recalled events from fictional stories, in which pairs of temporally distant events involving side characters (“sideplots”) either formed one coherent narrative or two unrelated narratives. Across participants, we varied whether recall was assessed immediately after learning, or after a delay: 24 hours, 12 hours between morning and evening (“wake”), or 12 hours between evening and morning (“sleep”). Participants recalled more information about coherent than unrelated narrative events, in most delay conditions, including immediate recall and wake conditions, suggesting that post-encoding consolidation was not necessary to integrate temporally distant events into a larger narrative. Furthermore, post hoc modeling across experiments suggested that narrative coherence facilitated recall over and above any effects of sentence-level semantic similarity. This reliable memory benefit for coherent narrative events supports theoretical accounts which propose that narratives provide a high-level architecture for episodic memory.

Multilabel Text Classification Menggunakan SVM dan Doc2Vec Classification Pada Dokumen Berita Bahasa Indonesia
Authors: Gunawan Kristian Indradiarta , Santoso Joan
Published: April 2021

Seiring dengan berkembangnya informasi yang ada di sekitar dengan pesat, maka jenis informasi yang ada pun menjadi sangat bervariasi dan sangat banyak jumlahnya, dan akan semakin terus bertambah. Dengan kondisi tersebut, kita akan mengalami kesulitan untuk mengenali jenis dari informasi tersebut satu persatu. Oleh karena itu dengan adanya proses klasifikasi teks dan dokumen sangatlah membantu untuk memilah dan mengenali informasi-informasi apa saja yang ada, baik informasi yang lama maupun informasi yang baru dan belum pernah ditemui sebelumnya. Bertujuan untuk dapat mengidentifikasi dan mengklasifikasikan dokumen-dokumen berita dalam bahasa Indonesia ke dalam beberapa kategori sekaligus, maka dibuatlah sebuah penelitian berupa sistem untuk menangani klasifikasi dokumen teks dalam bahasa Indonesia. Sistem tersebut akan memproses berita-berita yang diberikan, dan kemudian akan memberikan 2 kategori yang paling mendekati terhadap isi dari berita tersebut. Sistem dibuat dengan menggunakan Python, memanfaatkan Doc2Vec untuk mengambil fitur dataset, dan SVM untuk melakukan klasifikasi terhadap banyak kelas. Dataset yang digunakan adalah kumpulan dokumen berupa berita-berita yang diperoleh dari CNN Indonesia tahun 2016-2017, dan terbagi dalam 5 kategori berita utama, yaitu: Politik, Ekonomi, Teknologi, Olahraga, dan Hiburan. Dikarenakan sedikitnya literatur untuk klasifikasi text dalam bahasa Indonesia, maka pada penelitian ini hanya menargetkan akurasi sebesar 70% saja. Namun dari hasil ujicoba, akurasi yang diperoleh melebihi 90%. Hasil prediksi untuk kelas dokumen pun memiliki tingkat keberhasilan yang tinggi. Dengan penggunaan dataset dan penanganan preprocessing yang tepat untuk dokumen bahasa Indonesia, maka hasil yang dicapai bisa lebih bagus dan akurat.
Studi Analisa Kalman Filter Sebagai State Estimator Untuk Meningkatkan Akurasi Pengukuran Kecepatan Motor DC

State estimator merupakan sebuah teknik yang digunakan untuk mengestimasi besarnya suatu sinyal dari suatu data yang telah tercampur dengan noise. Noise tersebut dapat terjadi pada proses di dalam suatu plant (motor DC) maupun pada pembacaan oleh sensor, yang menyebabkan nilai yang sesungguhnya dari suatu sinyal tidak dapat diketahui dengan akurat. Sinyal yang tercampur dengan noise tersebut dapat direduksi dengan berbagai cara, di antaranya adalah dengan menggunakan Kalman Filter. Kalman Filter merupakan sebuah state estimator yang merupakan filter linier terbaik (bila semua syarat terpenuhi) dengan menggunakan konsep Minimum Mean Square Error (MMSE).

Dalam tugas akhir ini akan diuji coba dan diamati manfaat Kalman Filter untuk mengestimasi nilai kecepatan motor DC yang sesungguhnya bila sistem tersebut bekerja pada kondisi yang bernoise. Sebagai pembanding, dalam tugas akhir ini akan diuji coba juga teknik pemfilteran data yang lain untuk dibandingkan performansinya terhadap Kalman Filter.

Pengujian dilakukan dengan menggunakan program Matlab dengan cara memberikan noise ke dalam sistem. Hasil uji coba menunjukkan bahwa Kalman Filter mampu mereduksi error pada pengukuran kecepatan motor DC hingga kurang dari 0.5 rad/sec hanya dalam waktu 0.025 detik.
« Taxer la richesse ! »

Cet article, basé sur des entretiens, des observations et l’analyse de documents officiels, étudie la contribution des partis allemands à l’élaboration des politiques publiques fiscales. L’analyse des propositions d’un nouvel impôt sur la fortune par certains partis de gauche entre 2010 et 2017 permet de comprendre pourquoi ces organisations s’apparentent à des espaces d’intermédiation entre élus et acteurs extra-partisans. L’analyse se concentre à la fois sur les propriétés d’élus intervenant dans ces processus d’intermédiation et sur les effets des structures partisanes caractérisées par l’institutionnalisation des intérêts sociaux au sein d’organisations intrapartisanes. Nous constatons que les partis allemands parviennent à se présenter comme des forums politiques où s’élaborent à la fois des dispositifs fiscaux et des prises de position face aux politiques publiques engagées par leurs adversaires.
Où se construit la ligne du parti ?
Authors: Martinache Igor
Published: April 2021

À partir d’une analyse du traitement des enjeux liés au sport au sein du Parti communiste français (PCF) depuis sa création, cet article propose d’interroger les représentations communes qui envisagent la construction doctrinale au sein des organisations partisanes comme un processus centralisé impliquant un nombre réduit de dirigeants et dont le résultat se diffuserait ensuite de manière descendante. Ce cas doublement limite, du fait de la relégation des enjeux sportifs et de la place particulière du PCF dans le champ politique, suggère au contraire qu’un tel travail ne s’élabore pas simplement au sein des commissions dédiées, qui peuvent du reste représenter elles-mêmes des espaces assez ouverts aux influences extérieures, mais aussi et peut-être surtout à travers les politiques publiques mises en œuvre par des exécutifs nationaux ou locaux dont les agents portent les couleurs du parti concerné, en fonction de leurs propres dispositions militantes et de la configuration socio-politique où elles se déploient.
La fabrique des biens programmatiques au parti socialiste
Authors: Cos Rafaël
Published: April 2021

La manière dont les partis dits « de gouvernement » anticipent le fait d’avoir à conduire des réformes d’action publique constitue un angle mort de la littérature. En croisant l’exploitation d’archives et de données prosopographiques avec des entretiens conduits auprès de cadres du Parti socialiste et des « experts » ayant collaboré avec celui-ci, cet article explore les dimensions du travail programmatique partisan. En interrogeant la manière dont les politiques publiques s’articulent aux objectifs, contraintes et ressources d’une entreprise de gouvernement , l’article montre d’une part que les politiques publiques existent à la fois comme un horizon légitimateur encastré dans l’ordinaire des pratiques partisanes, et comme une échéance virtuelle orientant la mobilisation des ressources en campagne. Il souligne d’autre part combien ce double ressort se réfracte selon les multiples valeurs d’usage (récolte des suffrages, compétitions intra- puis inter-partisane, mise en jeu de sa crédibilité gestionnaire, fixation de coalitions réformatrices, préparation technique de l’échéance gouvernementale, etc.) dont sont investies les mobilisations programmatiques. C’est à l’intérieur de l’écart pratique entre ces différentes dimensions que les acteurs partisans s’ajustent – en bricolant – à la perspective de gouverner.
