Prospective observational study of single- or multi-compartment pressure ulcer prevention cushions: PRESCAROH project
Authors: Meaume S. , Marty M. , Colin D.
Published: September 2017

Objective:

In patients with reduced mobility, specialised pressure-relieving supports (mattresses, beds and cushions) are widely used to reduce or relieve the interface pressure between the skin and support surfaces to prevent incidence of pressure ulcers (PUs). The primary objective of these two observational studies was to assess the incidence of PUs in patients at high risk of PUs, seated in a wheelchair using a single- or multi-compartment air cushion. The level of patient satisfaction with the comfort and the views of the care team that used the air cushions were considered as secondary objectives.

Method:

The PRESCAROH project was two prospective observational studies conducted in patients free of PUs at baseline and at high risk of PUs (Braden score ≤13 or ≤16 for people with spinal cord injury). Patients had to spend more than eight hours a day in a wheelchair and use either a single-compartment air cushion (patient without asymmetry of support) for the first study or a multi-compartment air cushion (patient with asymmetry of support) for the second study. The primary end point was the percentage of patients in whom a PU (sacrum and/or ischium) developed over a 35-day period. The analysis was performed on the full-analysis set (FAS) of patients included with at least a second assessment.

Results:

We recruited 152 patients, 78 seated on a single-compartment air cushion (SiCAC group) and 74 on a multi-compartment air cushion (MuCAC group), in the two independent studies. All patients were included in the FAS (n=152). Most patients had spinal cord injuries. The average time spent sitting was 10.2 (standard deviation (SD): 2.3) hours a day in the SiCAC group and 9.1 (SD: 1.9) hours a day in the MuCAC group. In the SiCAC group, 6.4% (5/78) of patients dropped out of the study (one patient because of pulmonary infection and four patients for cushion installation problems). In the MuCAC group, 8.1% (6/74) of patients dropped out of the study (three patients because of adverse events not related to cushions, two for onset of PU, one for cushion-related problem). Over the study period of 35 days, 2.6% (2/78) [95% confidence interval (CI): 0.3–9.0%] of patients in the SiCAC group and 4.0% (3/74) [95%CI: 0.8–11.4%] in the MuCAC group developed a PU.

Conclusion:

These two observational studies showed that in patients at high risk of PUs and seated for more than eight hours a day in a wheelchair, the use of a single-compartment or multi-compartment air cushion with telescopic cells was associated with a low incidence of PUs.
Affect, aliens, and crisis in Nacho Vigalondo’s Extraterrestre
Authors: Divine Susan
Published: September 2017

This article will analyse how Nacho Vialgondo’s Extraterrestre (2011) first deploys and then intentionally confuses genre tropes as a way to comment on the housing crisis in Spain that was reaching its apex at the time of the film’s release. Specifically, Extraterrestre, marketed as a science fiction thriller, tells the story of an alien invasion in Madrid through the emotional arc of a melodrama. While staying away from overtly political commentary, Extraterrestre’s focus on romance and the home emphasizes how individuals respond in moments of crisis. Rather than focus on heroes who fight a spatial invasion and deterritorilization, the writer-director follows four protagonists who decide to isolate themselves from the outside danger, too absorbed in their romantic trysts to react rationally. This generic juxtaposition creates emotional dissonance in the spectator that allows for a consideration of affect as tool of hegemony. Social geographer Nigel Thrift refers to the relationship between affect and power as an ‘emotional regime’ that is manipulated by political, spatial and economic actors. To this end, my reading of the film is primarily informed by urban theory, especially how affect is produced and, in turn, produces space.

Published: September 2017

Education is an important factor in human resource investment. Education is also expected to increase income as well as decrease income inequality among workers. This paper analyzes returns to education in Indonesia. By processing the National Labor Force Survey data from six regions in Indonesia in 2013, we suggest a robust stylised fact: returns to education are higher for the more skilled individuals (workers who have high schooling). In other words, education can reduce income inequality. Income inequality occures because of over-education, ability–schooling interactions and school quality or different fields of study. Based on gender, returns to education for men is lower than for women. Education can reduce gender based income gap. Therefore, government can increase investment in education sector to reduce income inequality, including gender based income gap.

A large number of population that not followed by the quality of human resources will burden the development of a country. Thus, some efforts are needed to reduce the fertility level. One solution to this issue is to delay the first birth. This study aims to assess the delayed first child birth in rural Indonesia and the affecting factors. This study analyzed secondary data using descriptive approach to have a general description of the delayed first birth. Moreover, a binary logistic regression model was fitted to determine the associated factors.  The results show that a socioeconomic variable that significantly associated with the delayed first child birth is husband’s job in the non-agricultural sector. Furthermore, the significant demographic variables are the age of first marriage age and the perception of an ideal number of children.

Published: September 2017

The development of postsurgical hypoparathyroidism is the most frequent complication of thyroidectomy and radical surgical procedures on the neck. Hypoparathyroidism is a disorder characterized by hypocalcemia, parathyroid hormone (PTH) deficiency, and abnormal bone remodeling. Standard treatment of hypoparathyroidism consists of oral calcium and active forms of vitamin D. However, some patients fail to achieve the normalization of calcium levels with this therapy. We present a clinical case of postsurgical hypoparathyroidism with severe clinical presentation of hypocalcaemia treated with recombinant human PTH 1-34 - teriparatide.
Leveraging set relations in exact set similarity join
Authors: Wang Xubo , Qin Lu , Lin Xuemin , Zhang Ying , Chang Lijun
Published: September 2017

Exact set similarity join, which finds all the similar set pairs from two collections of sets, is a fundamental problem with a wide range of applications. The existing solutions for set similarity join follow a filtering-verification framework, which generates a list of candidate pairs through scanning indexes in the filtering phase, and reports those similar pairs in the verification phase. Though much research has been conducted on this problem, set relations, which we find out is quite effective on improving the algorithm efficiency through computational cost sharing, have never been studied. Therefore, in this paper, instead of considering each set individually, we explore the set relations in different levels to reduce the overall computational costs. First, it has been shown that most of the computational time is spent on the filtering phase, which can be quadratic to the number of sets in the worst case for the existing solutions. Thus we explore index-level set relations to reduce the filtering cost to be linear to the size of the input while keeping the same filtering power. We achieve this by grouping related sets into blocks in the index and skipping useless index probes in joins. Second, we explore answer-level set relations to further improve the algorithm based on the intuition that if two sets are similar, their answers may have a large overlap. We derive an algorithm which incrementally generates the answer of one set from an already computed answer of another similar set rather than compute the answer from scratch to reduce the computational cost. Finally, we conduct extensive performance studies using 21 real datasets with various data properties from a wide range of domains. The experimental results demonstrate that our algorithm outperforms all the existing algorithms across all datasets and can achieve more than an order of magnitude speedup against the state- of-the-art algorithms.

This is in response to recent feedback from some readers, which requires some clarifications regarding our IEJ

algorithm published in [1]. The feedback revolves around four points: (1) a typo in our illustrating example of the join process; (2) a naming error for the index used by our algorithm to improve the bit array scan; (3) the sort order used in our algorithms; and (4) a missing explanation on how duplicates are handled by our self join algorithm.
Flexible online task assignment in real-time spatial data

Published: September 2017

The popularity of Online To Offline (O2O) service platforms has spurred the need for online task assignment in real-time spatial data, where streams of spatially distributed tasks and workers are matched in real time such that the total number of assigned pairs is maximized. Existing online task assignment models assume that each worker is either assigned a task immediately or waits for a subsequent task at a fixed location once she/he appears on the platform. Yet in practice a worker may actively move around rather than passively wait in place if no task is assigned. In this paper, we define a new problem
Flexible Two-sided Online task Assignment
(FTOA). FTOA aims to guide idle workers based on the prediction of tasks and workers so as to increase the total number of assigned worker-task pairs. To address the FTOA problem, we face two challenges: (i) How to generate guidance for idle workers based on the prediction of the spatiotemporal distribution of tasks and workers? (ii) How to leverage the guidance of workers' movements to optimize the online task assignment? To this end, we propose a novel two-step framework, which integrates
offline prediction
and
online task assignment.
Specifically, we estimate the distributions of tasks and workers per time slot and per unit area, and design an online task assignment algorithm,
Prediction-oriented Online task Assignment in Real-time spatial data
(POLAR-OP). It yields a 0.47-competitive ratio, which is nearly twice better than that of the state-of-the-art. POLAR-OP also reduces the time complexity to process each newly-arrived task/worker to O(1). We validate the effectiveness and efficiency of our methods via extensive experiments on both synthetic datasets and real-world datasets from a large-scale taxi-calling platform.
Distributed trajectory similarity search

Published: September 2017

Mobile and sensing devices have already become ubiquitous. They have made tracking moving objects an easy task. As a result, mobile applications like Uber and many IoT projects have generated massive amounts of trajectory data that can no longer be processed by a single machine efficiently. Among the typical query operations over trajectories, similarity search is a common yet expensive operator in querying trajectory data. It is useful for applications in different domains such as traffic and transportation optimizations, weather forecast and modeling, and sports analytics. It is also a fundamental operator for many important mining operations such as clustering and classification of trajectories. In this paper, we propose a distributed query framework to process trajectory similarity search over a large set of trajectories. We have implemented the proposed framework in Spark, a popular distributed data processing engine, by carefully considering different design choices. Our query framework supports both the Hausdorff distance the Fréchet distance. Extensive experiments have demonstrated the excellent scalability and query efficiency achieved by our design, compared to other methods and design alternatives.
Privacy-preserving network provenance

Published: September 2017

Network accountability, forensic analysis, and failure diagnosis are becoming increasingly important for network management and security.
Network provenance
significantly aids network administrators in these tasks by explaining system behavior and revealing the dependencies between system states. Although resourceful, network provenance can sometimes be too rich, revealing potentially sensitive information that was involved in system execution. In this paper, we propose a cryptographic approach to preserve the confidentiality of provenance (sub)graphs while allowing users to query and access the parts of the graph for which they are authorized. Our proposed solution is a novel application of searchable symmetric encryption (SSE) and more generally structured encryption (SE). Our SE-enabled provenance system allows a node to enforce access control policies over its provenance data even after the data has been shipped to remote nodes (
e.g.
, for optimization purposes). We present a prototype of our design and demonstrate its practicality, scalability, and efficiency for both provenance maintenance and querying.
Query-able Kafka

Published: September 2017

Due to their promise of delivering real-time network insights, today's streaming analytics platforms are increasingly being used in the communications networks where the impact of the insights go beyond sentiment and trend analysis to include real-time detection of security attacks and prediction of network state (i.e., is the network transitioning towards an outage). Current streaming analytics platforms operate under the assumption that arriving traffic is to the order of kilobytes produced at very high frequencies. However, communications networks, especially the telecommunication networks, challenge this assumption because some of the arriving traffic in these networks is to the order of gigabytes, but produced at medium to low velocities. Furthermore, these large datasets may need to be ingested in their entirety to render network insights in real-time. Our interest is to subject today's streaming analytics platforms --- constructed from state-of-the art software components (Kafka, Spark, HDFS, ElasticSearch) --- to traffic densities observed in such communications networks. We find that filtering on such large datasets is best done in a common upstream point instead of being pushed to, and repeated, in downstream components. To demonstrate the advantages of such an approach, we modify Apache Kafka to perform limited
native
data transformation and filtering, relieving the downstream Spark application from doing this. Our approach outperforms four prevalent analytics pipeline architectures with negligible overhead compared to standard Kafka. (Our modifications to Apache Kafka are publicly available at https://github.com/Esquive/queryable-kafka.git)
Resumable online index rebuild in SQL server

Published: September 2017

Azure SQL Database and the upcoming release of SQL Server enhance Online Index Rebuild to provide fault-tolerance and allow index rebuild operations to resume after a system failure or a user-initiated pause. SQL Server is the first commercial DBMS to support pause and resume functionality for index rebuilds. This is achieved by splitting the operation into incremental units of work and persisting the required state so that it can be resumed later with minimal loss of progress. At the same time, the proposed technology minimizes the log space required for the operation to succeed, making it possible to rebuild large indexes using only a small, constant amount of log space. These capabilities are critical to guarantee the reliability of these operations in an environment where a) the database sizes are increasing at a much faster pace compared to the available hardware, b) system failures are frequent in Cloud architectures using commodity hardware, c) software upgrades and other maintenance tasks are automatically handled by the Cloud platforms, introducing further unexpected failures for the users and d) most modern applications need to be available 24/7 and have very tight maintenance windows. This paper describes the design of "Resumable Online Index Rebuild" and discusses how this technology can be extended to cover more schema management operations in the future.

Executing domain specific workloads from a relational data warehouse is an increasingly popular task. Unfortunately, classic relational database management systems (RDBMS) are suboptimal in many domains (e.g., graph and linear algebra queries), and it is challenging to transfer data from an RDBMS to a domain specific toolkit in an efficient manner. This demonstration showcases the EmptyHeaded engine: an interactive query processing engine that leverages a novel query architecture to support efficient execution in multiple domains. To enable a unified design, the EmptyHeaded architecture is built around recent theoretical advancements in join processing and automated in-query data transformations. This demonstration highlights the strengths and weaknesses of this novel type of query processing architecture while showcasing its flexibility in multiple domains. In particular, attendees will use EmptyHeaded's Jupyter notebook front-end to interactively learn the theoretical advantages of this new (and largely unknown) approach and directly observe its performance impact in multiple domains.

Recently, exploratory search has received much attention in information retrieval and database fields. This search paradigm assists users who do not have a clear search intent and are unfamiliar with the underlying data space. Specifically, query formulation evolves iteratively as the user becomes more familiar with the content. Despite its growing importance, exploratory search on graph-structured data has received little attention in the literature. We demonstrate a system called
picasso
to realize exploratory
sub-structure search
on a graph database containing a set of small or medium-sized data graphs.

Published: September 2017

New data has been generated in an unexpected high speed. To get insight of those data, data analysts will perform a thorough study using state-of-the-art big data analytical tools. Before the analysis starts, a preprocessing is conducted, where data analyst tends to issue a few ad-hoc queries on a new dataset to explore and gain a better understanding. However, it is costly to perform such ad-hoc queries on large scale data using traditional data management systems, e.g., DBMS, because data loading and indexing are very expensive. In this demo, we propose a novel visual data explorer system, FlashView, which omits the loading process by directly querying raw data. FlashView applies approximate query processing technique to achieve real-time query results. It builds both in-memory index and disk index to facilitate the data scanning. It also supports tracking and updating multiple queries concurrently. Note that FlashView is not designed as a replacement of full-fledged DBMS. Instead, it tries to help the analysts quickly understand the characteristics of data, so he/she can selectively load data into the DBMS to do more sophisticated analysis.

Community retrieval (CR) algorithms, which enable the extraction of subgraphs from large social networks (e.g., Facebook and Twitter), have attracted tremendous interest. Various CR solutions, such as
k
-core and
codicil
, have been proposed to obtain graphs whose vertices are closely related. In this paper, we propose the
C-Explorer
system to assist users in extracting, visualizing, and analyzing communities.
C-Explorer
provides online and interactive CR facilities, allowing a user to view her interesting graphs, indicate her required vertex
q
, and display the communities to which
q
belongs. A seminal feature of
C-Explorer
is that it uses an
attributed graph
, whose vertices are associated with labels and keywords, and looks for an
attributed community
(or AC), whose vertices are structurally and semantically related. Moreover,
C-Explorer
implements several state-of-the-art CR algorithms, as well as functions for analyzing their effectiveness. We plan to make
C-Explorer
an open-source web-based platform, and design API functions for software developers to test their CR algorithms in our system.

Allocation and usage of memory in modern data-processing platforms is based on an interplay of algorithms at multiple levels: (i) at the resource-management level across containers allocated by resource managers like Mesos and Yarn, (ii) at the container level among the OS and processes such as the Java Virtual Machine (JVM), (iii) at the framework level for caching, aggregation, data shuffles, and application data structures, and (iv) at the JVM level across various pools such as the Young and Old Generation as well as the heap versus off-heap. We use Thoth, a data-driven platform for multi-system cluster management, to build a deep understanding of different interplays in memory management options. Through multiple memory management
apps
built in Thoth, we demonstrate how Thoth can deal with multiple levels of memory management as well as multi-tenant nature of clusters.

Causal inference from observational data is a subject of active research and development in statistics and computer science. Many statistical software packages have been developed for this purpose. However, these toolkits do not scale to large datasets. We propose and demonstrate ZaliQL: a SQL-based framework for drawing causal inference from observational data. ZaliQL supports the state-of-the-art methods for causal inference and runs at scale within PostgreSQL database system. In addition, we built a visual interface to wrap around ZaliQL. In our demonstration, we will use this GUI to show a live investigation of the causal effect of different weather conditions on flight delays.
Summarizing static and dynamic big graphs

Published: September 2017

Large-scale, highly-interconnected networks pervade our society and the natural world around us, including the World Wide Web, social networks, knowledge graphs, genome and scientific databases, medical and government records. The massive scale of graph data often surpasses the available computation and storage resources. Besides, users get overwhelmed by the daunting task of understanding and using such graphs due to their sheer volume and complexity. Hence, there is a critical need to summarize large graphs into concise forms that can be more easily visualized, processed, and managed. Graph summarization has indeed attracted a lot of interests from various research communities, such as sociology, physics, chemistry, bioinformatics, and computer science. Different ways of summarizing graphs have been invented that are often complementary to each other. In this tutorial, we discuss algorithmic advances on graph summarization in the context of both classical (e.g., static graphs) and emerging (e.g., dynamic and stream graphs) applications. We emphasize the current challenges and highlight some future research directions.

At SYSU, the introduction occurred in three stages: leading edge (2001–2003); beginning (2004–2008); and comprehensive development (2009–). Following these stages, SYSU launched a full range of programs offering education and training in preservation and conservation, and has formed the SYSU Model, which relies on the first-level discipline, Science of Library, Information and Archive Management.

China's Ministry of Education stipulates that in the establishment of the graduate education system of colleges and universities, the first-level discipline is the major discipline and the second-level discipline is a subclass of it. In total, there are 110 first-level disciplines. The science of Library, Information and Archive Management is one of them.

In the process, it has also developed unique characteristics, such as effective integration of Chinese and Western theories; attaching equal importance to preservation and conservation; and an effective combination of theory and practice.

T-Cell Mediation of Pregnancy Analgesia Affecting Chronic Pain in Mice
Authors: Rosen Sarah F. , Ham Boram , Drouin Shannon , Boachie Nadia , Chabot-Dore Anne-Julie , Austin Jean-Sebastien , Diatchenko Luda , Mogil Jeffrey S.
Published: September 2017

It has been reported consistently that many female chronic pain sufferers have an attenuation of symptoms during pregnancy. Rats display increased pain tolerance during pregnancy due to an increase in opioid receptors in the spinal cord. Past studies did not consider the role of non-neuronal cells, which are now known to play an important role in chronic pain processing. Using an inflammatory (complete Freund's adjuvant) or neuropathic (spared nerve injury) model of persistent pain, we observed that young adult female mice in early pregnancy switch from a microglia-independent to a microglia-dependent pain hypersensitivity mechanism. During late pregnancy, female mice show no evidence of chronic pain whatsoever. This pregnancy-related analgesia is reversible by intrathecal administration of naloxone, suggesting an opioid-mediated mechanism; pharmacological and genetic data suggest the importance of δ-opioid receptors. We also observe that T-cell-deficient (nudeandRag1-null mutant) pregnant mice do not exhibit pregnancy analgesia, which can be rescued with the adoptive transfer of CD4+or CD8+T cells from late-pregnant wild-type mice. These results suggest that T cells are a mediator of the opioid analgesia exhibited during pregnancy.

SIGNIFICANCE STATEMENTChronic pain symptoms often subside during pregnancy. This pregnancy-related analgesia has been demonstrated for acute pain in rats. Here, we show that pregnancy analgesia can produce a complete cessation of chronic pain behaviors in mice. We show that the phenomenon is dependent on pregnancy hormones (estrogen and progesterone), δ-opioid receptors, and T cells of the adaptive immune system. These findings add to the recent but growing evidence of sex-specific T-cell involvement in chronic pain processing.
Kaldor after Ricardo, Keynes, and Kalecki: Perspectives on theory and policies
Authors: Holland Stuart
Published: September 2017

Nicholas Kaldor was a progressive force in economics who made several major contributions, which are well covered by other contributors to this issue in his memory. Yet, like most first generation Keynesians, he stayed within the paradigm of The Concluding Notes to the General Theory, in which Keynes claimed that provided the State intervened to manage the level of demand, the supply side of an economy could be left to the processes of perfect or imperfect competition, whereas Kalecki realised that oligopoly could influence both macroeconomic aggregates and policies. Like Keynes, he also assumed, with Ricardo, that trade was between different firms in different countries rather than recognising that capital already was multinational and that this could qualify both exchange rate changes such as that of the sterling in 1967 and his regional employment premium and selective employment tax.
KETAHANAN DALAM AIR DAN PELEPASAN NITROGEN & FOSFOR KE AIR MEDIA DARI BERBAGAI PAKAN IKAN AIR TAWAR
Authors: Sukadi M. Fatuchri
Published: September 2017

Limbah dan sisa pakan ikan yang tidak termakan dan lepas ke lingkungan air budidaya bisa memberikan kontribusi terhadap penambahan unsur nitrogen (N) dan fosfor (P) ke lingkungan perairan budidaya. Ada 17 jenis pakan ikan komersial yang beredar dan digunakan pembudidaya khususnya oleh pembudidaya keramba jaring apung di Waduk Cirata dan Jatiluhur. Pakan yang beredar tersebut belum diketahui performanya terkait dengan ketahanan dalam air (water stability) serta pelepasan N dan P dari pakan tersebut ke air media. Penelitian ini menentukan ketahanan pakan dalam air dari ke-17 pakan tersebut yang dikaitkan dengan pelepasan N dan P dari pakan setelah 10, 20, dan 30 menit pakan direndam dalam air. Hasil penelitian menunjukkan bahwa hubungan kandungan total P dalam pakan berkorelasi linier dengan pelepasan unsur P ke dalam air. Bila kandungan P pakan rendah (<2%) maka rendah pula P yang dilepas ke air media. Makin baik ketahanan pakan dalam air, makin rendah P yang dilepas ke dalam air. Ketahanan pakan dalam air yang tinggi masih memberikan kecenderungan tingginya pelepasan N ke dalam air. Hasil analisis proksimat dari 17 pakan tersebut kandungan proteinnya berkisar antara 26,00%–29,83%; total N 4,04%–4,77%; dan total P antara 1,38%–5,18%.

Purpose: The purpose of this study is to describe the characteristics of the newborn and its surgical pathologies managed in the service of pediatric surgery of the National Hospital of Lamordé. Patients and Methods: It is a retrospective and descriptive study within a period of 10 years (from January 1st 2007 till December 31st 2016). The epidemiological, diagnostic, therapeutic, and evolutionary aspects were also studied. Results: The surgical pathologies of the newborn child represented 12.8 % of the hospitalized patients. The average annual incidence was 47.5 newborn children a year. The average age was of 8.71 days. The newborn children were especially old from 0 to 7 days (60,2 %) and were male (66.1 %). The most frequent pathologies were the malformations anorectales (32,2 %), the omphalocele (18.3 %), and the gastrochisis (6.5 %). The surgical operations, realized for 67.7 % patients, were especially emergencies (58.2 %). The colostomy was the most realized intervention (41.9 %). The mortality rate was 25.8 % (n=123). The post-operative mortality was 16.9 % and the nonoperative mortality was 45%. The premature mortality established 70 % of deaths (n=75). The omphalocele was the main pathology supplier of death (26 %). Conclusion: The neonatal surgical pathologies are characterized by their frequency, their diversity, the predominance of digestive system pathologies, and a high mortality. An evaluation of pronostic factors which determines the morbi-mortality is necessary.
Influence of Height‐Based Management on Forage Nutritive Value of Four Warm‐Season Forage Grasses

Core Ideas

Change in nutritive value was analyzed based on height for warm‐season grasses.

Herbage mass was estimated for each species at designated height.

Predictive models based on herbage mass may be helpful for producers.

Harvest timing is an influential factor in providing animals with high quality forage. Height‐based management is commonly practiced to determine timing of cutting or grazing. This study aimed to observe nutritive value changes in tall‐ and short‐growing warm‐season grasses with repeated cuttings. The experiment was conducted at the University of Tennessee Plateau AgResearch and Education Center in Crossville, TN, from 2013 to 2015. Four forages were evaluated, each for 2 yr: switchgrass [Panicum virgatum (L.) cv. Alamo], bermudagrass [Cynodon dactylon (L.) Pers. cv. Vaughn's #1], a sorghum × sudangrass hybrid [Sorghum bicolor (L.) Moench × Sorghum sudanese (P.) Stapf, cv. FSG208BMR], and crabgrass [Digitaria sanguinalis (L.) cv. Quick‐N‐Big]. Height‐prescribed cutting treatments were established for each species, replicated four times, and arranged in a randomized complete block design. The regrowth forage was sampled weekly for nutritive value analysis using near‐infrared spectroscopy and morphological composition on a dry mass basis. Most nutritive value variables did not differ between first and second cut at 1 and 2 wk postcutting (P < 0.05) but often differed at 3 wk postcutting. Similar patterns were observed for morphological components. In all cases, crude protein (CP) was positively correlated with proportion of lamina (r > 0.50). A negative linear relationship was observed between CP and herbage mass in switchgrass, sorghum × sudangrass, and bermudagrass (r2 > 0.20, P < 0.05). This information can be used by producers to determine appropriate cutting frequency and estimate forage nutritive value in the field from herbage mass (HM).

Identification of outstanding maize (Zea mays L.) hybrids for target environments is complicated by genotype × environment interactions. Thirty‐two early‐maturity maize hybrids were evaluated at eight locations in Nigeria and six locations in Ghana for 2 yr to (i) identify high‐yielding, stable hybrids across locations and/or hybrids specifically adapted to different locations, and (ii) identify ideal test sites for selection of superior hybrids in the two countries. Genotype, country, year, location (country), and their interactive effects were significant (P < 0·01) for grain yield, days to anthesis and silking, anthesis‐silking interval, plant and ear aspects, and ears per plant. Mean grain yield of the hybrids ranged from 3177 kg ha−1 for EWH‐5 to 4596 kg ha−1 for EWH‐29. The genotype main effects plus genotype × environment interaction (GGE) biplot analysis revealed that EWH‐29, EWH‐8, and EWH‐30 did not differ significantly in grain yield and were the most stable hybrids in both countries, whereas EWH‐26 and EWH‐32 were the most stable hybrids only in Ghana. The GGE biplot analysis identified Samaru, Kafin Soli, and Minjibir in Nigeria and Nyankpala, Damongo, and Fumesua in Ghana as the most discriminating locations. Minjibir (Nigeria) and Nyankpala (Ghana), being most discriminating and representative locations, were considered the ideal testing sites for the respective countries. The type of cultivars evaluated determined the most suitable locations for multilocation testing within Ghana and Nigeria. Whereas hybrids EWH‐29, EWH‐8, and EWH‐30 should be suitable for production in Nigeria, EWH‐26 and EWH‐32 should be promoted for production in Ghana.
Negative factors of beliefs toward advertising on Facebook and their effect on attitudes
Authors: Bongazana Dondolo Hilda
Published: September 2017

Previous research has studied the effects of materialism, value corruption and falsity, which were identified by Pollay and Mittal (1993) as negatively impacting the beliefs about advertising. Few, if any, assessed negative beliefs about Facebook advertising. This paper assesses such beliefs and how these beliefs influence attitudes toward advertising on Facebook. To meet the objectives of the study, 269 undergraduate students completed the questionnaire. Regression analysis was used to examine a relationship between the beliefs about Facebook advertising and attitudes. In line with hypotheses developed for this study, results showed that respondents of this study view Facebook advertising as promoting materialism, corrupting society’s values and misleading and thus negatively impacting their attitudes toward Facebook advertising. This paper concludes with the discussion of results and offers the limitation of the study. The study also provides directions for future research.

Fokus penelitian pada pemberitaan penggunaan jilbab bagi polisi wanita dalam Surat Kabar Harian Republika, dengan jenis berita straight news. Penelitian bertujuan untuk menge­tahui, mendeskripsikan, dan menganilisis konstruksi wacana Surat Kabar Harian Republika mengenai pem­beritaan peng­­­­gunaan jilbab bagi polisi wanita. Penelitian ini meng­guna­­kan jenis penelitian kualitatif dengan metode analisis wacana Teun A van Dijk. Teknik pengumpulan data pe­nelitian meng­gunak­an dokumentasi teks berita dalam Surat Kabar Harian Republika edisi Juni-Desember 2013. Penelitian menghasilkan simpulan mengenai konstruksi wacana dalam pemberitaan peng­gunaan jilbab polwan yaitu, pertama, Re­publika tidak se­tuju saat Kapolri belum mengizinkan penggunaan jilbab polwan, alasannya bertolak belakang dengan Undang-Undang Dasar 1945 dan perintah agama untuk menutup aurat. Kedua, Republika mendukung sikap Kapolri saat memberi izin secara lisan kepada polwan untuk berjilbab dan menghendaki segera ada peraturan yang memperkuat kebijakan. Ketiga, Republika tidak setuju adanya peraturan penundaan penggunaan jilbab polwan, menganggap ganjil ke­bijakan tersebut, dan me­mandang terdapat kelompok anti­jilbab di tubuh kepolisian. Republika terlihat mengharap­kan polwan dapat bebas ber­jilbab saat bertugas tanpa perlu mengkhawatirkan adanya teguran. Hal tersebut terlihat dari pemilihan narasumber berita yang kebanyakan memiliki harap­an sama dengan Republika. Kutipan wawancara narasumber yang menginginkan polwan berjilbab diberi porsi lebih banyak dan ada yang diletakkan pada awal serta akhir berita. Penulis memberikan saran bagi wartawan untuk lebih berimbang dalam meyajikan berita, baik dari pemilihan narasumber, peletakan kutipan wawan­cara, maupun pengambilan sudut pandang, agar tidak terlihat berpihak dan menjadi berita provokasi. Penulis memberi rekomendasi kepada Polri untuk memasukkan jilbab dalam standard operating procedure seragam dinas kepolisian. Hal tersebut dimaksudkan agar polisi wanita tidak terlalu lama me­­nunggu Parlemen me­nye­tujui anggaran penyediaan jilbab, karena menutup aurat menjadi hak yang dilindungi konstitusi. Bagi DPR, seharusnya membuat kebijakan atau undang- undang yang menjamin penggunaan jilbab dan berlaku di ting­kat nasional
FAKTA POLIGAMI SEBAGAI BENTUK KEKERASAN TERHADAP PEREMPUAN
Authors: Hikmah Siti
Published: September 2017

Poligami merupakan suatu jalan yang diambil per­empu­an karena keterpaksaan. Poligami menjadi suatu dilema, di­terima ataupun tidak tetap memiliki konse­kuensi terjadi­­nya kekerasan ter­hadap per­empu­an. Istri pertama maupun kedua, sama sama terjerat dan tertindas dalam sistem kemasyarakatan yang di­kuasai oleh sistem masya­rakat patriarkhi. Berangkat dari ana­lisa tersebut, maka segala argumen yang menyatakan bahwa poligami telah menyelamatkan per­empuan tidak benar sama sekali.
Praktek perkawinan poligami lebih berdampak ke­madharatan daripada kemaslahatan. Dalam per­kawin­an poligami banyak terjadi pengabaian hak-hak kemanusia­an yang semestinya didapatkan oleh seorang istri dan anak dalam keluarga. Hal ini yang kemudian sering muncul adalah adanya permusuhan di antara keluarga para istri dalam perkawinan poli­gami. Realitasnya banyak kasus poligami yang me­micu bentuk-bentuk kekerasan dalam rumah tang­ga (KDRT) lainnya, meliputi kekeras­an fisik, psikis, seksual dan ekonomi dan sebagai­nya yang dialami oleh perempuan dan anak-anak men­jadi bukti bahwa semestinya ada peninjauan dan pertimbangan kembali tentang adanya praktek per­kawinan poli­gami.
