Peningkatan Hasil Belajar IPS dan Self Esteem Siswa SD melalui Multimedia dalam Pembelajaran IPS

Penelitian ini bertujuan untuk membandingkan peningkatan hasil belajar IPS dan self esteem siswa yang pembelajarannya menggunakan multimedia dan konvensional. Penelitian ini adalah penelitian kuantitatif dengan metode kuasi eksperimen dan desain yang digunakankelompok kontrol non ekivalendengan instrumen penelitian yang digunakan berupa tes hasil belajar IPS dan non-tes (self esteem). Data yang dianalisis adalah data pretes, postes, dan n-gain. Hasil penelitian menunjukkan bahwa peningkatan hasil belajar IPSdan self esteem siswa setelah mendapatkan pembelajaran dengan multimedia lebih baik dibandingkan dengan siswa yang mendapatkan pembelajaran IPS secara konvensional; Tidak terdapat hubungan yang positif antara hasil belajar IPS siswa dan self esteem siswa dalam pembelajaran yang menggunakan pembelajaran dengan multimedia

Perilaku Pemeriksaan Kesehatan Ibu Hamil Dan Pemilihan Penolong Persalinan Di Kabupaten Sukabumi

Maternal mortality and infant mortality are important indicators to state the social welfare andpublic health status of country. The both are correlated with health status of pregnant woment, knowledgeof women and family of antenatal care; delivery assistant and accessibility of health facility. The objectiveof this study is to identify the practice of ANC and utilization of delivery assisstant. The study usedqualitative methode with indepth interview and focus group discussion (FGD) to pregnant women,neonatus\u27s mother, key persons, traditional birth attendants (TBA) and midwife villages. The result of thisstudy showed that the community have the ANC awareness but some of them still prefer to ask TBA whendelivery. Factors influence TBA\u27s preference were 1) economics; 2) culture; 3) geography reason; 4)psycology; 5) pragmatis; 6) Service satifaction

Perception of Neighborhood Around the Real Estate Physical Boundary

The presence of real estate in South Tangerang cannot be separated from a surrounding settlement or new settlements that grew later. Regulation and design are more set-in real estate planning so that real estate tends to form an enclave for security and social image. Forming some type of physical boundary with surrounding residential of real estate perceived vary both by residents and outside the real estate. This study aims to map out how the perception of the surrounding community to the physical boundaries of real estate on a cluster pattern made by the developer, with research sites in Bintaro Jaya, South Tangerang. The method used observation and structured interviews with communities. The surrounding community has very positively responded to the presence of real estate, but the relationship with the institution is perceived as not useful because of the boundary design is more detrimental for them. Their participation in the plan has not been well accommodated so that access is closed unilaterally by the developer.The presence of real estate in South Tangerang cannot be separate from a surrounding settlement or new settlements that grew later.

Why is Polygyny More Prevalent in Western Africa?: An African Slave Trade Perspective

Polygyny rates are higher in Western Africa than in Eastern Africa. The African slave trades explain this difference. More male slaves were exported in the trans-Atlantic slave trades from Western Africa, while more female slaves were exported in the Indian Ocean and Red Sea slave trades from Eastern Africa. The slave trades led to prolonged periods of abnormal sex ratios, which impacted the rates of polygyny across Africa. In order to assess these claims, we construct a unique ethnicity-level data set linking current rates of polygyny with historical trade flow data from the African slave trades. Our OLS estimates show a positive correlation between the trans-Atlantic slave trades and polygyny. An IV approach shows the relationship is causal and statistically signicant. We also provide cross-country evidence corroborating our findings.slave trades; polygyny; Africa; development

Secrecy performance of TAS/SC-based multi-hop harvest-to-transmit cognitive WSNs under joint constraint of interference and hardware imperfection

In this paper, we evaluate the secrecy performance of multi-hop cognitive wireless sensor networks (WSNs). In the secondary network, a source transmits its data to a destination via the multi-hop relaying model using the transmit antenna selection (TAS)/selection combining (SC) technique at each hop, in the presence of an eavesdropper who wants to receive the data illegally. The secondary transmitters, including the source and intermediate relays, have to harvest energy from radio-frequency signals of a power beacon for transmitting the source data. Moreover, their transmit power must be adjusted to satisfy the quality of service (QoS) of the primary network. Under the joint impact of hardware imperfection and interference constraint, expressions for the transmit power for the secondary transmitters are derived. We also derive exact and asymptotic expressions of secrecy outage probability (SOP) and probability of non-zero secrecy capacity (PNSC) for the proposed protocol over Rayleigh fading channel. The derivations are then verified by Monte Carlo simulations.Web of Science195art. no. 116

Rapidly Rotating Fermi Gases

We show that the density profile of a Fermi gas in rapidly rotating potential will develop prominent features reflecting the underlying Landau level like energy spectrum. Depending on the aspect ratio of the trap, these features can be a sequence of ellipsoidal volumes or a sequence of quantized steps.Comment: 4 pages, 1 postscript fil

Approximation by finite mixtures of continuous density functions that vanish at infinity

Given sufficiently many components, it is often cited that finite mixture models can approximate any other probability density function (pdf) to an arbitrary degree of accuracy. Unfortunately, the nature of this approximation result is often left unclear. We prove that finite mixture models constructed from pdfs in $\mathcal{C}_{0}$ can be used to conduct approximation of various classes of approximands in a number of different modes. That is, we prove approximands in $\mathcal{C}_{0}$ can be uniformly approximated, approximands in $\mathcal{C}_{b}$ can be uniformly approximated on compact sets, and approximands in $\mathcal{L}_{p}$ can be approximated with respect to the $\mathcal{L}_{p}$, for $p\in\left[1,\infty\right)$. Furthermore, we also prove that measurable functions can be approximated, almost everywhere

The Effect of Family Interaction and Decision-Making Toward Marital Quality of Family with Migrant Husband

Lagging economic conditions, especially in rural areas cause residents leave their hometown or become a migrant to get a job in order to meet the family needs. This study aimed to analyze the influence of family characteristics, family interaction, and decision-making on marital quality in families with migrant husband. The design of this study was cross sectional study involving wives, who had migrant husbands and teenage children (age 12-18), as respondents. The study was conducted in Banyuresmi Village, Garut Regency, West Java, Indonesia which were selected purposively. Data were collected through interview using questionnaire. The results showed that family income and conjugal interaction were the factors that allowed an increase in marital quality. On the other hand, decision-making did not have a significant effect on marital quality of the family with migrant husban
